Summary of the Invention

Problem to be Solved by the Invention

[0004] However, if the roll body stops while moving from the storage device to the feeding position, tape feeding may not be performed.

[0005] Therefore, an object of the present invention is to provide a component mounting system or the like that can cope even if the tape roll body stops while moving from the storage device to the feeding position.

Means for Solving the Problem

[0006] (1) A component mounting system according to one aspect of the present invention comprises a component supply device for supplying components, a tape supply device for supplying a storage device for storing a roll of carrier tape to the component supply device, and a component mounting device for mounting the components supplied by the component supply device onto a substrate, wherein the component supply device includes a component supply unit for supplying components by pulling in a carrier tape containing the components, a device holding unit for detachably holding the storage device, and a receiving device for receiving the roll that has moved from the storage device due to the pulling in of the component supply unit, and the tape supply device includes a detection unit for detecting the roll along the movement path of the roll from the storage device to the receiving device.

[0007] According to these findings, the detection unit detects the roll body along its movement path, and based on the detection result, it can determine whether or not the roll body is stopped along its movement path. Therefore, if it is determined that the roll body is stopped along its movement path, it can be addressed accordingly.

[0008] (2) In the component mounting system described in (1) above, the detection unit may be an optical sensor, and the optical axis of the optical sensor may intersect the movement path of the roll body moving between the storage device and the receiving device.

[0009] According to this, since the optical axis of the optical sensor intersects with the movement path of the roll body as it moves between the storage device and the receiving device, it is possible to easily detect when the roll body has stopped midway along its movement path using the optical sensor.

[0010] (3) In the component mounting system described in (2) above, the optical sensor may be a length measuring sensor.

[0011] According to this, since the detection unit is a length measuring sensor, it is possible to easily detect the stopping of the roll without using a camera or the like.

[0012] (4) In the component mounting system described in (3) above, the tape supply device may include a determination unit that determines whether the distance to the object to be detected, as measured by the length measuring sensor, is greater than or equal to a predetermined value, and a notification unit that notifies an error when it is determined that the distance is not greater than or equal to a predetermined position.

[0013] According to this system, if the judgment unit determines that the distance to the object being detected, as measured by the length measuring sensor, is not equal to or greater than a predetermined value, the notification unit will notify the operator of the roll stopping. This allows for a quick response to the roll stopping.

[0014] (5) In the component mounting system described in (4) above, the tape supply device may have a recovery unit that recovers an empty storage device from the component supply device when it is determined that the distance is greater than or equal to a predetermined position.

[0015] According to this, if the judgment unit determines that the distance is greater than a predetermined position, the retrieval unit retrieves the empty storage device from the trolley, so that the empty storage device can be retrieved even when the roll body is not stopped. In other words, it is possible to prevent the stopped roll body from getting in the way while the empty storage device is being retrieved.

[0016] (6) In the component mounting system described in (4) or (5) above, the predetermined value may vary depending on the size of the storage device or the outer diameter of the roll body.

[0017] According to this, the predetermined value differs depending on the size of the storage device or the outer diameter of the roll body, so an appropriate predetermined value is set for each storage device of different size or roll body of different outer diameter. This makes it possible to reliably determine when to stop roll bodies of different sizes.

[0018] (7) A tape supply device according to one aspect of the present invention is a tape supply device that supplies a storage device for storing a roll of carrier tape to a parts supply device that supplies parts, wherein the parts supply device comprises a device holding unit that detachably holds the storage device and a receiving device that receives the roll that has moved from the storage device when the parts supply device pulls it in, and the tape supply device has a detection unit that detects the roll along the movement path of the roll from the storage device to the receiving device.

[0019] According to this, the detection unit detects the roll body along its movement path, and based on the detection result of the detection unit, it is possible to determine whether or not the roll body is stopped along its movement path. Therefore, if it is determined that the roll body is stopped along its movement path, it is possible to take appropriate action.

[0020] (8) A component mounting system according to one aspect of the present invention comprises a component supply device for supplying components, a tape supply device for supplying a storage device for storing a roll of carrier tape to the component supply device, and a component mounting device for mounting the components supplied by the component supply device onto a substrate, wherein the component supply device includes a component supply unit for supplying components by pulling in a carrier tape containing the components, a device holding unit for detachably holding the storage device, a receiving device for receiving the roll that has moved from the storage device due to the pull-in of the component supply unit, and a detection unit for detecting the roll along the movement path of the roll from the storage device to the receiving device.

[0021] According to this, the detection unit detects the roll body along its movement path, and based on the detection result of the detection unit, it is possible to determine whether or not the roll body is stopped along its movement path. Therefore, if it is determined that the roll body is stopped along its movement path, it is possible to take appropriate action.

[0022] (9) In the component mounting system according to (9) above, the component supply device may include a moving unit that moves the detection unit in the arrangement direction of the plurality of device holding units.

[0023] According to this configuration, since the component supply device includes the moving unit that moves the detection unit in the arrangement direction of the plurality of device holding units, a single detection unit can detect a roll body that has stopped midway along the movement path to each device holding unit.

[0024] (10) A trolley according to one aspect of the present invention is a component supply device for supplying components, comprising: a device holding unit that detachably holds a storage device storing a roll of carrier tape; a component supply unit that draws in the carrier tape storing the components to supply the components; a receiving device that receives the roll body moved from the storage device by the drawing operation of the component supply unit; and a detection unit that detects the roll body midway along the movement path of the roll body from the storage device to the receiving device.

[0025] According to this configuration, since the detection unit detects the roll body midway along the movement path of the roll body, it can be determined whether the roll body stops midway along the movement path based on the detection result of the detection unit. Therefore, when it is determined that the roll body stops midway along the movement path, measures can be taken to deal with this situation. Effects of the Invention

[0026] According to the present invention, even if a tape roll body stops while moving from the storage device to the feeding position, countermeasures can be taken. Brief Description of the Drawings

[0028] Hereinafter, an embodiment of the present invention and a component mounting system according to its modifications will be described with reference to the drawings. The embodiments and modifications described below are all general or specific examples. The numerical values, shapes, materials, components, arrangement positions of components, and connection configurations shown in the following embodiments and modifications are examples and are not intended to limit the present invention. Furthermore, each figure is a schematic diagram, and dimensions, etc., are not necessarily shown precisely. In addition, the same or similar components are denoted by the same reference numerals in each figure. In the following description, the X-axis direction is the width direction of each device (component mounting device 20, trolley 30, and tape supply device 40) provided in the component mounting system 10, the Y-axis direction is the direction in which each device is arranged, and the Z-axis direction is the height direction (vertical direction) of each device. The Y-axis direction is also the connection direction of the trolley 30 to the component mounting device 20.

[0029] Furthermore, expressions indicating relative directions or orientations, such as parallel and orthogonal, include cases where the direction or orientation is not strictly accurate. For example, two directions being parallel does not only mean that the two directions are perfectly parallel, but also that they are substantially parallel, meaning that there may be a difference of, for example, a few percent. Moreover, simply saying "in the X-axis direction" means either the bidirectional or unidirectional direction parallel to the X-axis. The same applies to terminology related to the Y-axis and Z-axis.

[0030] (First embodiment) Figure 1 is an explanatory diagram showing the schematic configuration of a component mounting system 10 according to the first embodiment. As shown in Figure 1, the component mounting system 10 according to the first embodiment comprises a component mounting device 20, a trolley 30, and a tape supply device 40. The component mounting system 10 is an example of a component supply system.

[0031] The component mounting device 20 is a device that mounts components supplied by a component supply unit 31 on a trolley 30 onto a substrate 50. Specifically, the component mounting device 20 includes a head 21 that takes components 87 (see Figure 5) from the component supply unit 31 and transfers and mounts them onto the substrate 50, a substrate transport unit 22 that transports the substrate 50 with the components 87 mounted by the head 21 to a subsequent reflow apparatus (not shown), and a positioning device 23 that positions the trolley 30.

[0032] The trolley 30 is a trolley equipped with a parts supply unit 31 that pulls in a carrier tape 83 (see Figure 5) for storing parts 87 and supplies the parts 87, and a device holding unit 70 (see Figure 2, etc.) that detachably holds a plurality of storage devices 60 for storing the roll body 80 of the carrier tape 83.

[0033] The tape supply device 40 is a device that supplies the storage device 60 to the device holding section 70 of the trolley 30, and removes an empty storage device 60 from the device holding section 70.

[0034] [Cart] Next, the details of the trolley 30 will be described. The trolley 30 is an example of a parts supply device. Figure 2 is a side view showing the trolley 30 and the positioning device 23 according to the first embodiment. In Figure 2, the trolley 30 is shown separated from the positioning device 23. Figure 3 is a perspective view showing the trolley 30 according to the first embodiment. Figure 4 shows the trolley 30 according to the first embodiment with the first storage device 61, which is an example of a storage device 60, and the second storage device 65, which is an example of a storage device 60, removed. In Figure 4, both the first receiving device 38 and the second receiving device 39 provided on the trolley 30 are shown removed.

[0035] As shown in Figures 2 to 4, the trolley 30 includes a parts supply unit 31, a plurality of device holding units 70, and a trolley body 32 that supports them. The parts supply unit 31 has a plurality of feeders 311 arranged in the X-axis direction in pairs with each device holding unit 70, but in Figure 3 only the feeders 311 at both ends in the X-axis direction are shown. Each feeder 311 pulls out a carrier tape 83 from a storage device 60 (first storage device 61 or second storage device 65) held by each device holding unit 70, and transports the parts stored on the carrier tape 83 to the retrieval position by the head 21.

[0036] The trolley body 32 has a base 300 and a plurality of casters 33 attached to the underside of the base 300, and these casters 33 allow it to move freely on the floor surface.

[0037] On the base 300, a parts supply unit 31 is positioned in the positive Y-axis direction, and multiple device holding parts 70 are arranged in the X-axis direction in the negative Y-axis direction. For example, a pair of holding wall parts 34 are erected on the base 300 in the positive Y-axis direction. A unit holding part 312 for holding the parts supply unit 31 is provided on the pair of holding wall parts 34 so as to be able to move up and down. Positioning rollers 313 are provided at both ends of the unit holding part 312 in the X-axis direction for positioning each of the holding wall parts 34 with respect to the positioning device 23.

[0038] On the base 300, in the negative Y-axis direction, there is a support base 35 and a height adjustment section 36 (described later: see Figure 18, etc.) which connects the support base 35 and the base 300 and adjusts the height position of the support base 35.

[0039] The support base 35 is the part that supports multiple device holding parts 70. At both ends of the support base 35 in the X-axis direction, a pair of support columns 351 and 352 are provided, arranged in the Y-axis direction. A first roller 353, which is positioned relative to the positioning device 23, is provided at the upper end of the support column 351 in the Y-axis positive direction. A second roller 354, which is positioned relative to the positioning device 23, is provided at the upper end of the support column 352 in the Y-axis negative direction. The first roller 353 and the second roller 354 are aligned along the connection direction (Y-axis direction) of the trolley 30 to the component mounting device 20, and the first roller 353 is positioned higher than the second roller 354. The first roller 353 and the second roller 354 are examples of rollers and move together with each device holding part 70.

[0040] Multiple device holders 70 supported by the support base 35 are each designed to detachably hold either a first storage device 61 or a second storage device 65. Similarly, each device holder 70 is designed to detachably hold either a first receiving device 38 or a second receiving device 39. For example, when the first storage device 61 is attached to a predetermined device holder 70, the first receiving device 38 is attached to the same device holder 70. In this case, the first storage device 61 is positioned in the negative Y-axis direction, and the first receiving device 38 is positioned in the positive Y-axis direction.

[0041] On the other hand, when a second storage device 65 is attached to a predetermined device holding section 70, a second receiving device 39 is attached to the device holding section 70. In this case, the second storage device 65 is positioned in the negative Y-axis direction, and the second receiving device 39 is positioned in the positive Y-axis direction.

[0042] [Carrier Tape] Figure 5 is a perspective view showing the schematic configuration of a carrier tape 83 that constitutes a roll body 80 according to the first embodiment. As shown in Figure 5, the carrier tape 83 has a tape body 85 having a plurality of component pockets 84, and a cover tape 86 that is attached to the tape body 85 and covers each component pocket 84. Component pockets 84 contain components 87. In the tape body 85, a plurality of feed holes 88 are formed at positions exposed from the cover tape 86, into which the sprocket 314 of the feeder 311 (see Figure 13A, etc.) engages. By winding this carrier tape 83, a roll body 80 (see Figure 6, etc.) is formed.

[0043] [Storage device] Next, the details of the storage device 60 will be described. The storage device 60 is also an example of a supply device that supplies carrier tape 83 to the parts supply unit 31. The first storage device 61 and the second storage device 65, which are examples of the storage device 60, differ in that they store rolls of different sizes. For example, the first storage device 61 is designed to store larger rolls 80 than the second storage device 65. For this reason, the first storage device 61 itself is also larger than the second storage device 65. The size of the rolls 80 varies depending on the type of parts that the carrier tape 83 stores. Hereinafter, the rolls 80 stored in the first storage device 61 will be referred to as the first rolls 81, and the rolls 80 stored in the second storage device 65 will be referred to as the second rolls 82.

[0044] First, as an example of the storage device 60, the first storage device 61 will be described. Figure 6 is an exploded perspective view showing a part of the first storage device 61 according to the first embodiment. As shown in Figure 6, the first storage device 61 comprises a first main body 63, a first tape feeding unit 93, and a first holding unit 94. The first main body 63 is an example of a main body, the first tape feeding unit 93 is an example of a tape feeding unit, and the first holding unit 94 is an example of a holding unit.

[0045] The first storage device 61 has a flattened outer shape with the X-axis direction as the thickness direction. In the first storage device 61, the upper surface 611 is formed parallel to the XY plane, and the base end surface 612 in the negative Y-axis direction is formed parallel to the XZ plane. When the first storage device 61 is held by the device holding part 70, the upper surface 611 is approximately equal to the first reference plane parallel to the XY plane, and the base end surface 612 is approximately equal to the second reference plane parallel to the XZ plane.

[0046] The first main body 63 is the main part of the first storage device 61 and comprises a first storage section 62 and a first housing section 64. The first storage section 62 is an example of a storage section, and the first housing section 64 is an example of a housing section.

[0047] The first storage section 62 is located below the first storage section 64. The first storage section 62 has a first storage space H1 (storage space) for storing the first roll body 81. Specifically, the first storage section 62 is composed of a first frame body 621 and a pair of first cover bodies 622, and the space formed by these is the first storage space H1.

[0048] The first frame body 621 is a substantially U-shaped frame with the positive Y-axis direction open when viewed in the X-axis direction. A pair of first cover bodies 622 are formed in a flat plate shape and are attached to the first frame body 621 so as to sandwich it in the X-axis direction. As a result, each first cover body 622 covers the recess of the first frame body 621 in the X-axis direction. The recess of the first frame body 621 and the pair of first cover bodies 622 constitute the first storage space H1. When the unused first roll body 81 is stored in the first storage space H1, the pair of first cover bodies 622 completely cover the first roll body 81. The first storage space H1 is open in the positive Y-axis direction. That is, an opening 623 is provided at the end of the first storage section 62 that is close to the parts supply unit 31. The opening 623 is an example of a first opening. This opening 623 allows the first roll body 81 to move back and forth along the Y-axis direction relative to the first storage space H1. The first roll body 81 passes through the opening 623 when exiting the first storage space H1. The lower tip of the first frame body 621 is provided with a fall prevention part 624 to prevent the first roll body 81 from falling out of the opening 623. Details of the fall prevention part 624 will be described later.

[0049] A first housing section 64 is positioned above the first frame body 621. The first housing section 64 houses the first tape feeding section 93 and the first holding section 94. The upper part of the first housing section 64 is the gripped section 625. The first housing section 64 is formed by the first frame body 621, a pair of first cover bodies 622, and the gripped section 625, and is a concave section extending in the Y-axis direction with its end in the Y-axis positive direction open.

[0050] A pair of leaf springs 621a and 621b are attached to the upper part of the first frame body 621 to restrict the movement of the first holding part 94. In other words, the pair of leaf springs 621a and 621b are located inside the first housing part 64. The pair of leaf springs 621a and 621b are arranged along the Y-axis direction, and their ends in the positive Y-axis direction protrude upward.

[0051] The gripped portion 625 is the part that is gripped by the tape supply device 40. In other words, when the first storage device 61 is supplied to the device holding portion 70 by the tape supply device 40, or when it is removed from the device holding portion 70, the gripped portion 625 is gripped by the gripping portion 42 (see Figure 28) of the tape supply device 40. The gripped portion 625 has recesses formed on both sides in the Y-axis direction, into which the gripping portion 42 of the tape supply device 40 is inserted. A tag 626 that stores information about the components housed in the first roll body 81 is provided on the upper surface of the gripped portion 625. This tag 626 is read by a tag reader 43 (see Figure 28) provided on the gripping portion 42.

[0052] Next, a second storage device 65 will be described as an example of the storage device 60. Figure 7 is an exploded perspective view of a part of the second storage device 65 according to the first embodiment. As shown in Figure 7, the second storage device 65 comprises a second main body 67, a second tape feeding unit 293, and a second holding unit 294. The second main body 67 is an example of a main body, the second tape feeding unit 293 is an example of a tape feeding unit, and the second holding unit 294 is an example of a holding unit.

[0053] The second storage device 65 has a flattened outer shape with the X-axis direction as the thickness direction. In the second storage device 65, the upper surface 651 is formed parallel to the XY plane, and the base end surface 652 in the negative Y-axis direction is formed parallel to the XZ plane. When the second storage device 65 is held by the device holding part 70, the upper surface 651 is approximately equal to the first reference plane parallel to the XY plane, and the base end surface 652 is approximately equal to the second reference plane parallel to the XZ plane.

[0054] The second main body 67 is the main part of the second storage device 65 and includes a second storage section 66 and a second housing section 68. The second storage section 66 is an example of a storage section, and the second housing section 68 is an example of a housing section.

[0055] The second storage device 65 differs from the first storage device 61 in that the second storage section 66 is smaller than the first storage section 62, but the basic structure is generally the same. Therefore, this section will describe the parts of the second storage device 65 that differ from the first storage device 61, and other parts will be given the same reference numerals as the first storage device 61 and described accordingly. For example, the gripped portion 625 of the first storage device 61 and the second storage device 65 have the same structure. Therefore, the gripped portion 625 of the first storage device 61 is an example of the first gripped portion, and the gripped portion 625 of the second storage device 65 is an example of the second gripped portion.

[0056] The second storage section 66 is located below the second storage section 68. The second storage section 66 has a second frame body 661 and a pair of second cover bodies 662 that form a second storage space H2 (storage space) for storing the second roll body 82. The second storage space H2 is smaller than the first storage space H1. When the unused second roll body 82 is stored in the second storage space H2, the pair of second cover bodies 662 completely cover the second roll body 82. The second roll body 82 is able to move back and forth along the Y-axis direction relative to the second storage space H2 through the opening 663 of the second storage section 66. When the second roll body 82 exits the second storage space H2, it passes through the opening 663. The opening 663 is an example of a first opening.

[0057] [Tape feeding and holding section] Next, the tape feeding section and the tape holding section will be described. Here, the first tape feeding section 93 will be given as an example of the tape feeding section, and the first holding section 94 will be given as an example of the holding section, while the description of the second tape feeding section 293 and the second holding section 294 will be omitted.

[0058] Figure 8 is a perspective view showing the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment. In Figure 8, the first cover body 622 in the positive X-axis direction is omitted from the illustration. Figures 9 and 10 are exploded perspective views showing the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment. Figures 9 and 10 are perspective views of the first tape feeding unit 93 and the first holding unit 94 viewed from different directions.

[0059] As shown in Figures 8 to 10, the first tape feeding section 93 and the first holding section 94 are located between the first frame body 621 and the gripped section 625, that is, within the first housing section 64. The first tape feeding section 93 is the part that feeds the leading edge of the carrier tape 83 to the parts supply unit 31. The first holding section 94 is the part that holds the first tape feeding section 93 so that it can slide freely in the Y-axis direction.

[0060] First, let's describe the first holding part 94. The first holding part 94 has a holding body part 941, a first support part 942, and a second support part 943.

[0061] The retaining body portion 941 is a plate-like body with a tapered tip in the Y-axis positive direction. Specifically, the tip of the retaining body portion 941 has an inclined surface 944 at its lower edge, which slopes in the Z-axis positive direction toward the Y-axis positive direction. The inclination of the inclined surface 944 is referred to as the inclination direction. A guide groove 945 parallel to the inclined surface 944 is formed at the tip. In the guide groove 945, the portion from the center toward the Y-axis positive direction is closed in the X-axis positive direction, while the portion from the center toward the Y-axis negative direction is open in the X-axis direction. A convex groove portion 946 protruding in the Z-axis positive direction is formed in the center of the guide groove 945. The convex groove portion 946 is closed in the X-axis negative direction. A support shaft 947 protruding in the X-axis positive direction is formed on the inner surface of the convex groove portion 946. A torsion spring 948 is attached to the support shaft 947.

[0062] The tip of the holding body portion 941 has a thinned portion on the surface in the negative X-axis direction. This thinned portion is a housing recess 941a that movably accommodates the first tape feeding portion 93 (see Figure 11).

[0063] A groove-shaped contact portion 949 extending in the Z-axis direction is formed on the tip surface of the retaining body portion 941. A rectangular notch portion 950 is formed in the lower center of the retaining body portion 941. Above the notch portion 950 in the retaining body portion 941, a pair of elongated holes 951 and 952 extending in the Y-axis direction are formed. The pair of elongated holes 951 and 952 are positioned in the negative Y-axis direction relative to the convex groove portion 946.

[0064] The first support portion 942 and the second support portion 943 are sheet metal members that sandwich the holding body portion 941 in the X-axis direction. Specifically, the first support portion 942 is positioned in the positive X-axis direction of the holding body portion 941, and the second support portion 943 is positioned in the negative X-axis direction of the holding body portion 941.

[0065] Since the first support portion 942 and the second support portion 943 are basically the same shape, the specific shape of the first support portion 942 will be described here, and the part of the second support portion 943 corresponding to the first support portion 942 will be given the same reference numeral and its description will be omitted.

[0066] The first support portion 942 is a plate that is thinner than the holding body portion 941, and its external shape when viewed in the X-axis direction generally corresponds to that of the holding body portion 941. Specifically, the first support portion 942 has a tapered shape at the tip in the positive Y-axis direction, and the lower edge of the tip extends along the direction of inclination. An elongated hole 953 is formed in the tip along the direction of inclination.

[0067] A support piece 954 projecting downward is provided at the lower edge of the tip of the first support portion 942, and the lower end of this support piece 954 is bent toward the holding body portion 941. Furthermore, a protruding piece 955, also bent toward the holding body portion 941, is provided at the tip of the first support portion 942. A rectangular notch 956 is formed in the lower center of the first support portion 942. The first support portion 942 and the second support portion 943 are screwed together and integrated with the holding body portion 941.

[0068] Figure 11 is an exploded perspective view of the first tape feeding unit 93 according to the first embodiment. As shown in Figure 11, the first tape feeding unit 93 comprises a first member 96, a second member 97, and a third member 98, each made of sheet metal. These are assembled to the holding body 941 in the order of the first member 96, second member 97, and third member 98, starting from the negative X-axis direction. The second support unit 943 is positioned further in the negative X-axis direction than the first member 96 (see Figure 10).

[0069] The first member 96 has a pair of through holes 961 at the upper part of its end in the negative Y-axis direction, and is screwed to the holding body 941 through this pair of through holes 961. Specifically, a stepped portion 939 is formed in the receiving recess 941a of the holding body 941, and the pair of through holes 961 of the first member 96 are screwed to this stepped portion 939. The first member 96 has a pair of elongated holes 962 and 963 formed along the inclined direction.

[0070] The second member 97 is a long plate in the Y-axis direction, with its tip tapering in the Y-axis positive direction. A pair of claw portions 971 protrude from the Y-axis positive tip of the second member 97. The pair of claw portions 971 are inserted into and engage with a plurality of feed holes 88 of the carrier tape 83. In other words, the pair of claw portions 971 is an example of an engaging part.

[0071] A projection 972 is formed at the lower center of the second member 97, projecting in the negative direction of the X-axis. Three through-holes 973, 974, and 975 are formed in the second member 97. Specifically, the through-holes 973 and 974 are arranged along the Y-axis direction, and the through-holes 974 and 975 are arranged along the inclined direction. Bosses 973a, 974a, and 975a are attached to the through-holes 973, 974, and 975, respectively.

[0072] The third member 98 has a locking portion 981 that protrudes in the positive X-axis direction from the center of its upper part. The locking portion 981 is inserted into the upper of a pair of elongated holes 951 and 952 in the holding body 941, specifically the elongated hole 951. A coil spring 957 is housed in the elongated hole 951. The end of the coil spring 957 in the negative Y-axis direction is fixed to the holding body 941 within the elongated hole 951, and the end in the positive Y-axis direction is locked to the locking portion 981. This coil spring 957 biases the third member 98 and the holding body 941 relative to each other in the Y-axis direction.

[0073] In the third member 98, a pair of through-holes 982 are formed below the locking portion 981, arranged in the Y-axis direction. A boss 982a is attached to each through-hole 982. The boss 982a is inserted into the lower of the pair of elongated holes 951 and 952 in the holding body portion 941, specifically the elongated hole 952. As these bosses 982a are guided by the elongated holes 952, the third member 98 is able to move freely along the Y-axis direction while receiving a biasing force from the coil spring 957.

[0074] The third member 98 has a guide hole 983 extending in the Z-axis direction at its Y-axis positive end. The boss 973a of the second member 97 is inserted into the guide hole 983. The boss 973a is inserted into the Y-axis negative direction elongated hole 962 of the pair of elongated holes 962, 963 of the first member 96. On the other hand, the bosses 974a and 975a of the second member 97 are inserted into the Y-axis positive direction elongated hole 963 of the pair of elongated holes 962, 963 of the first member 96, and are also inserted into the guide groove 945 of the holding body 941. Therefore, when the second member 97 slides in the Y-axis direction relative to the holding body 941, it slides in an inclined direction due to the pair of elongated holes 962, 963, the guide hole 983, and the guide groove 945.

[0075] In this state, if the second member 97 is in the negative Y-axis direction from its predetermined position, the bosses 974a and 975a are in contact with the torsion spring 948 within the guide groove 945. In this state, the bosses 974a and 975a receive a biasing force in the positive Y-axis direction from the torsion spring 948, causing the second member 97 to move in the positive Y-axis direction relative to the holding body 941.

[0076] The following describes the method of supplying the carrier tape performed by the first tape feeding unit 93 and the first holding unit 94.

[0077] Figure 12 is an explanatory diagram showing the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment in a standby state. The position of the first holding unit 94 in the standby state is defined as the retracted position. Here, the first tape feeding unit 93 and the first holding unit 94 are housed slidably in the Y-axis direction between a pair of first cover bodies 622. In the standby state, the notch 950 of the first holding unit 94 abuts against the leaf spring 621a of a pair of leaf springs 621a and 621b, which is in the negative Y-axis direction. This restricts the movement of the first tape feeding unit 93 and the first holding unit 94. The leaf spring 621a is an example of a state-holding unit that holds the first holding unit 94 in the retracted position, that is, the first holding unit 94 in the standby state. In the standby state, the tip of the first holding unit 94 (the end in the positive Y-axis direction) protrudes from the first housing unit 64. In other words, in the retracted position, at least a part of the first holding unit 94 is housed by the first housing unit 64.

[0078] Figures 13A to 13D are explanatory diagrams showing the operation of the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment. Figures 14A to 14C are explanatory diagrams showing the internal operation of the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment. Figures 15A to 15C are explanatory diagrams showing the state of the first storage device 61 during the operation of the first tape feeding unit 93 and the first holding unit 94 according to the first embodiment. In Figures 14A to 14C, the holding body 941 is shown with a dashed line, and the first support unit 942 is not shown.

[0079] When the tape supply device 40 supplies the first storage device 61 to the device holding section 70 of the trolley 30, the tape supply device 40 pulls out the first tape feed section 93 and the first holding section 94, which are in a standby state, in the positive Y-axis direction. As shown in Figure 13A, the position of the first holding section 94 in the pulled-out state is defined as the extended position. Thus, the first holding section 94 is provided on the first main body 63 so as to be movable between the extended position and the retracted position, which is a position retracted from the extended position. In the extended position, the first holding section 94 protrudes more from the first storage section 64 than when it is in the retracted position.

[0080] At this time, the notch 950 of the first holding part 94 is in contact with the leaf spring 621b of the pair of leaf springs 621a and 621b, the leaf spring in the positive Y-axis direction. As a result, the first tape feeding part 93 and the first holding part 94 cannot move any further in the positive Y-axis direction. In this state, the pair of claws 971 of the first tape feeding part 93 are inserted into and engaged with the feed hole 88 at the leading edge of the carrier tape 83.

[0081] Subsequently, as shown in Figure 15A, the tape supply device 40 moves the first storage device 61 so that the tip of the first holding portion 94 contacts the feeder 311. Specifically, as shown in Figures 13B and 14A, the tape supply device 40 moves the first storage device 61 so that the contact portion 949 of the holding body portion 941 is pressed against the sprocket 314 of the feeder 311. At this time, the contact portion 949 is positioned in contact with the sprocket 314.

[0082] As the pressing progresses, the holding body 941 slides in the negative Y-axis direction relative to the first tape feeding unit 93, as shown in Figures 13C and 14B. In other words, the first holding unit 94 retracts from its extended position as its contact portion 949 is pressed against the sprocket 314. Relatively speaking, the first storage device 61 and the feeder 311 are shown that the sprocket 314 moves the first holding unit 94 from its extended position to its retracted position. In other words, the sprocket 314 is an example of a position-changing unit that moves the holding unit from its extended position to its retracted position. The position-changing unit may also be provided on the trolley 30 or the tape supply device 40.

[0083] As the contact portion 949 retracts, the second member 97, under the biasing force from the torsion spring 948, moves in the positive Y-axis direction relative to the retaining body portion 941. As a result, the pair of claw portions 971 of the second member 97 also slide gradually closer to the sprocket 314. Specifically, the pair of claw portions 971 slide diagonally downwards to diagonally upwards relative to the first retaining portion 94. Figure 14C shows the second member 97 in its most protruding state, that is, the state in which it is closest to the sprocket 314.

[0084] In this state, as shown in Figure 13D, the leading edge of the carrier tape 83, which is engaged with the pair of claws 971, is fed to the sprocket 314 based on the sliding of the pair of claws 971. The direction in which the carrier tape 83 is fed is along the Y-axis direction. In this way, the first tape feeding unit 93 feeds the leading edge of the carrier tape 83 to the sprocket 314 of the feeder 311 as the first holding unit 94 moves back from its extended position.

[0085] During this feeding process, the leading edge of the carrier tape 83 is supported up to a certain point by the support pieces 954 of the first support section 942 and the second support section 943, but this support is released partway through.

[0086] Figure 16 is an explanatory diagram showing the state in which the support pieces 954 of the first support portion 942 and the second support portion 943 of the first embodiment support the carrier tape 83, and the state in which the support is released. The carrier tape 83 is not shown in Figure 16.

[0087] In the state in which the carrier tape 83 is supported, the first support portion 942 and the second support portion 943 are not elastically deformed, and the distance H between the lower ends of each support piece 954 is narrower than the width of the carrier tape 83. The tip of the carrier tape 83 rests on the lower ends of each support piece 954 and is supported.

[0088] As the feed progresses, the second member 97 slides in the positive Y-axis direction, causing the projection 972 of the second member 97 to contact the support piece 954 of the second support portion 943, elastically deforming the second support portion 943. At this time, the tip of the second member 97 contacts the projection 955 of the second support portion 943, elastically deforming the second support portion 943. As a result, the distance H between the lower ends of each support piece 954 widens beyond the width of the carrier tape 83, thus releasing the support for the carrier tape 83. Thus, the second member 97 is an example of a support release member that releases the support for the carrier tape 83. After release, the tip of the carrier tape 83 descends from the lower ends of each support piece 954 and is fed to the sprocket 314.

[0089] Subsequently, as shown in Figure 15B, the tape supply device 40 further presses the first storage device 61 against the feeder 311 so that the first holding unit 94 moves to the retracted position. Here, the retracted position is defined as a position where the first tape feeding unit 93 and the first holding unit 94 do not interfere with the carrier tape 83 being pulled out by the feeder 311.

[0090] Subsequently, as shown in Figure 15C, the tape supply device 40 lowers the first storage device 61 and places it on the device holding section 70. Even after placement, the carrier tape 83 continues to be fed to the sprocket 314. Details of the device holding section 70 will be described later.

[0091] [Falling prevention part] Next, the fall prevention unit 624 will be described. Figure 17 is an explanatory diagram showing the fall prevention unit 624 according to the first embodiment. Figure 17 shows the fall prevention ON state and the fall prevention OFF state.

[0092] As shown in Figure 17, the fall prevention part 624 is located at the lower end of the first frame body 621. The fall prevention part 624 includes a first support column 627, a second support column 628, and a torsion spring 629. The first support column 627 is located in the negative Y-axis direction relative to the second support column 628, and its end in the negative Y-axis direction is rotatably supported by the first frame body 621. The second support column 628 is located below the first support column 627, and its end in the positive Y-axis direction is rotatably supported by the first frame body 621. The torsion spring 629 is located below the second support column 628 and biases the second support column 628 in an upright direction.

[0093] When the first storage device 61 is separated from the device holding part 70 of the trolley 30, the second support column 628 is in an upright position due to the torsion spring 629. As a result, the first support column 627 is also pushed up by the second support column 628 and supported in an upright position. This causes the first support column 627 to act as a barrier, preventing the first roll body 81 in the first storage space H1 from falling out of the opening 623 (anti-fall ON state). In the anti-fall ON state, the position of the anti-fall part 624 is the prevention position that prevents the first roll body 81 from falling out.

[0094] When the first storage device 61 is held by the device holding part 70, a convex switching member 79 provided on the device holding part 70 pushes down the second support column 628. For example, at the lower end of the first storage device 61 in the positive Y-axis direction, a slit-shaped insertion part 619 is formed, with the end in the positive Y-axis direction being open. The switching member 79 is formed from a block body. When this switching member 79 is inserted into the insertion part 619, it comes into contact with the second support column 628 and pushes down the second support column 628. As a result, the first support column 627 also falls over, allowing the first roll body 81 in the first storage space H1 to move through the opening 623 (fall prevention OFF state). In the fall prevention OFF state, the position of the fall prevention part 624 is an allowable position that permits the fall of the first roll body 81. In this state, since the switching member 79 is engaged with the insertion part 619, the movement of the first storage device 61 is restricted. In other words, the switching member 79 is an example of a restricting part.

[0095] [First receptor device and second receptor device] Next, the first receiving device 38 and the second receiving device 39 will be described. As shown in Figures 3 and 4, the first receiving device 38 is positioned in the Y-axis positive direction of the first storage device 61 held by the device holding section 70. The first receiving device 38 is a device that receives the first roll body 81 that has moved from the first storage device 61. The first receiving device 38 has a flattened outer shape with the X-axis direction as the thickness direction. The upper part of the first receiving device 38 is provided with a locking piece 382 that is locked to a support shaft 321 on the trolley body 32 that is parallel to the X-axis direction. The first receiving device 38 has an opening 381 formed at its end in the Y-axis positive direction, and the first roll body 81 is received by the first receiving device 38 through this opening 381. Thus, the first receiving device 38 is an example of a receiving device, and the opening 381 is an example of a second opening.

[0096] The second receiving device 39 is positioned in the Y-axis positive direction of the second storage device 65, which is held by the device holding section 70. The second receiving device 39 is a device that receives the second roll body 82 that has moved from the second storage device 65. The second receiving device 39 has a flattened outer shape with the X-axis direction as the thickness direction. A locking piece 392 is provided on the upper part of the second receiving device 39, which is locked to the support shaft 321 of the trolley body 32. The second receiving device 39 has an opening 391 formed at its end in the Y-axis positive direction, and the second roll body 82 is received by the second receiving device 39 through this opening 391. Thus, the second receiving device 39 is an example of a receiving device, and the opening 391 is an example of a second opening.

[0097] [Device holding part] Next, the device holding section 70 will be described. Figure 18 is a plan view showing the device holding section 70 according to the first embodiment. Figures 19A to 19C are plan views showing the operation of the device holding section 70 according to the first embodiment. Figure 19A shows the first posture in which the device holding section 70 holds the first storage device 61 in the first position. Figures 18 and 19C show the second posture in which the device holding section 70 holds the second storage device 65 in the second position. As shown, the second position is higher in height than the first position. Figure 19B shows the state in which the device holding section 70 is changing between the first and second postures.

[0098] The device holder 70 is provided so as to be able to move up and down relative to the trolley 30, and as shown in Figures 18 to 19C, the device holder 70 has a mounting section 71, a pair of legs 72, and a beam section 73.

[0099] The mounting section 71 is the area on which the first storage device 61 or the second storage device 65 is mounted, and is supported by a pair of legs 72. The mounting section 71 is formed in a rail shape with an open top, and the first storage device 61 or the second storage device 65 is inserted into this open section and mounted.

[0100] At the mounting portion 71, a fixing portion 711 is provided at the end in the negative Y-axis direction, projecting upward. Figure 20 is a perspective view showing the fixing portion 711 according to the first embodiment. Figure 20 shows the fixing portion 711 in the first or second posture. As shown in Figure 20, the fixing portion 711 has a shape that extends in the Z-axis direction, and is open in the positive Z-axis direction and the positive Y-axis direction. The first storage device 61 or the second storage device 65 is inserted into the open portion of the fixing portion 711 from the positive Z-axis direction, and the first storage device 61 or the second storage device 65 is fixed in place. In the middle portion of the fixing portion 711 in the Z-axis direction, a projection 712 is formed that projects in the negative Y-axis direction. A groove 713 extending in the Y-axis direction is formed in the projection 712.

[0101] As shown in Figures 18 to 19C, each pair of legs 72 has an upper limb 721 and a lower limb 722. The end of the upper limb 721 in the positive Z-axis direction rotatably supports the mounting section 71. The end of the lower limb 722 in the negative Z-axis direction rotatably supports the support base 35. The end of the upper limb 721 in the negative Z-axis direction and the end of the lower limb 722 in the positive Z-axis direction are rotatably connected. A beam section 73 is rotatably connected to the connection point between the upper limb 721 and the lower limb 722 in each of the two legs 72. In other words, the beam section 73 spans between the pair of legs 72.

[0102] As shown in Figure 19A, when the device holder 70 is in the first position, the upper limbs 721 and lower limbs 722 of each leg 72 are folded, and the mounting section 71 is in its lowest position. In this first position, the first storage device 61 is placed on the mounting section 71 and fixed by the fixing section 711. At this time, the first storage device 61 is held in the first position by the device holder 70. Thus, the device holder 70 holding the first storage device 61 in the first position is an example of the first device holder. In the first position, the device holder 70 holds the first storage device 61 on the Y-axis minus side and holds the first receiving device 38 on the Y-axis plus side. In other words, the first storage device 61 and the first receiving device 38 are held side by side along the Y-axis direction.

[0103] As shown in Figure 19C, when the device holder 70 is in the second position, the upper limbs 721 and lower limbs 722 of each leg 72 are extended in a straight line, and the mounting section 71 is at its highest position. In this second position, the second storage device 65 is placed on the mounting section 71 and fixed by the fixing section 711. At this time, the second storage device 65 is held in the second position by the device holder 70. Thus, the device holder 70 holding the second storage device 65 in the second position is an example of the second device holder. Also in this state, the end of the beam section 73 in the negative Y-axis direction protrudes from the leg 72. In the second position, the device holder 70 holds the second storage device 65 on the negative Y-axis side and the second receiving device 39 on the positive Y-axis side. In other words, the second storage device 65 and the second receiving device 39 are held side by side along the Y-axis direction.

[0104] The first storage device 61 held in the first position and the second storage device 65 held in the second position have upper surfaces 611 and 651 that are approximately equal to a first reference plane parallel to the XY plane, and base end surfaces 612 and 652 that are approximately equal to a second reference plane parallel to the XZ plane. Here, "approximately equal" means that the objects do not only coincide perfectly, but also that they are within a range of 3 mm or less. Furthermore, it is more preferable that they are within a range of 1.5 mm or less.

[0105] Switching between the first and second postures is performed by extending or retracting each leg 72, as shown in Figure 19B. Specifically, when switching from the first posture to the second posture, the folded legs 72 are extended (in the order of Figures 19A, 19B, and 19C). When switching from the second posture to the first posture, the extended legs 72 are folded (in the order of Figures 19C, 19B, and 19A).

[0106] The first storage device 61, held in the first position, and the second storage device 65, held in the second position, are fixed in place by a fixing device 37 (see Figure 21).

[0107] [Fixing fixture] Next, the fixing device 37 will be described. Figure 21 is a perspective view showing the installation location of the fixing device 37 according to the first embodiment. Figure 22 is a perspective view showing the fixing device 37 according to the first embodiment. In Figure 22, two fixing devices 37 are shown, with the fixing device 37 in the negative X-axis direction indicating the state in which the device holding part 70 is fixed in the first position, and the fixing device 37 in the positive X-axis direction indicating the state in which the device holding part 70 is fixed in the second position.

[0108] As shown in Figure 21, a shaft 359 extending in the X-axis direction is provided at the end of the support base 35 in the negative Y-axis direction, and a plurality of fasteners 37 are rotatably supported on this shaft 359. Each fastener 37 is provided in a one-to-one relationship with each device holding part 70.

[0109] As shown in Figure 22, the fixing device 37 is made of sheet metal. When the fixing device 37 is in a state where it is fixing the device holder 70 in the first position, it has a first stopper 371 that protrudes from the top in the positive Y-axis direction. The first stopper 371 fixes the device holder 70 in the first position by engaging with the groove 713 of the projection 712 of the device holder 70. When the first stopper 371 disengages from the groove 713, the device holder 70 becomes movable.

[0110] Furthermore, when the device holder 70 is fixed in the first position, the fixing device 37 has a handle portion 372 that protrudes downward and a second stopper 373 that is positioned away from the shaft 359 relative to the handle portion 372 and bent in the positive X-axis direction. When the handle portion 372 is operated manually or by the tape supply device 40, the fixing device 37 rotates around the shaft 359. The second stopper 373 fixes the device holder 70 in the second position by contacting the end of the beam portion 73 that protrudes from the leg portion 72 in the device holder 70 in the second position. When the second stopper 373 disengages from the end of the beam portion 73, the device holder 70 becomes movable.

[0111] [Height adjustment section] Next, the height adjustment section 36 provided on the support base 35 will be described. As shown in Figure 18, the height adjustment section 36 is positioned between the base 300 and the support base 35 and adjusts the height position of the support base 35 relative to the base 300 by extending and retracting in the Z-axis direction. In other words, the height adjustment section 36 indirectly adjusts the height of the device holding section 70 by adjusting the height of the support base 35. A pair of height adjustment sections 36 are provided at a predetermined interval in the X-axis direction, but since the basic structure is the same, the height adjustment section 36 in the X-axis positive direction will be described here.

[0112] Specifically, the height adjustment section 36 includes a vertical wall 361, a pair of first link members 362, a pair of second link members 363, and a beam section 364. The vertical wall 361 is a wall that rises from the upper surface of the base 300 and extends in the Y-axis direction. The pair of first link members 362 are arranged in the Y-axis direction, and the lower ends of each are rotatably connected to the vertical wall 361. The lower ends of the pair of second link members 363 are rotatably connected to the upper ends of each first link member 362, and the upper ends of each are rotatably connected to the support base 35. The beam section 364 is a beam that extends in the Y-axis direction and is rotatably connected to the connection positions of each first link member 362 and each second link member 363.

[0113] Figures 23A to 23C are explanatory diagrams showing the operation of the height adjustment section 36 according to the first embodiment. Figure 23A shows the height adjustment section 36 when the support base 35 is in its lowest position. In this case, each first link member 362 and each second link member 363 are in their most folded state.

[0114] Figure 23C shows the height adjustment section 36 when the support base 35 is at its highest position. In this case, each first link member 362 and each second link member 363 are in their most extended state.

[0115] Figure 23B shows the transition from the state shown in Figure 23A to the state shown in Figure 23C, or from the state shown in Figure 23C to the state shown in Figure 23A. In other words, when the support base 35 rises, the most folded first link members 362 and second link members 363 gradually extend (in the order of Figures 23A, 23B, and 23C). On the other hand, when the support base 35 lowers, the most extended first link members 362 and second link members 363 gradually fold (in the order of Figures 23C, 23B, and 23A).

[0116] In this process, the device holder 70 on the support base 35 is also height-adjusted, so the height position between the device holder 70 and the component mounting device 20 is also adjusted. In other words, the height adjustment unit 36 ​​adjusts the height position of the device holder 70 relative to the component mounting device 20.

[0117] [Positioning device] Next, the positioning device 23 of the component mounting device 20 will be described. The positioning device 23 is a device for positioning the trolley 30. Figure 24 is a perspective view of the positioning device 23 according to the first embodiment. As shown in Figure 24, the positioning device 23 has a pair of first positioning parts 230 arranged at a predetermined distance in the X-axis direction. The pair of first positioning parts 230 position the device holding part 70 in the height direction and horizontal direction relative to the component mounting device 20. The trolley 30 is housed between the pair of first positioning parts 230. Each first positioning part 230 has a guide base 231, a rail part 232, and a stopper 236.

[0118] The guide base 231 guides the height position of the device holding section 70 when the trolley 30 is connected to the parts mounting device 20. The guide base 231 supports the rail section 232 and the stopper 236. Furthermore, the upper surface of the guide base 231 in the negative Y-axis direction relative to the rail section 232 is a groove-shaped guide path 231a that guides the first roller 353 and the second roller 354 of the trolley 30.

[0119] The rail section 232 is a rail extending in the Y-axis direction, and its upper surface guides the first roller 353 of the trolley 30. The upper surface of the rail section 232 has a first inclined surface 234 and a second inclined surface 235 with different inclines. Specifically, the first inclined surface 234 is provided from the negative Y-axis direction to the central part of the rail section 232 and has an inclination toward the positive Z-axis direction toward the positive Y-axis direction. The second inclined surface 235 is provided at the end of the rail section 232 in the positive Y-axis direction and has an inclination toward the negative Z-axis direction toward the positive Y-axis direction.

[0120] Here, of the pair of first positioning parts 230, the second inclined surface 235 of the first positioning part 230 in the negative X-axis direction is flat overall. In contrast, the second inclined surface 235 of the first positioning part 230 in the positive X-axis direction has a pair of protrusions 237 formed at both ends in the X-axis direction.

[0121] The stopper 236 is positioned to be continuous with the end of the rail section 232 in the positive Y-axis direction, and is a column that is taller than the rail section 232.

[0122] [Connection operation between positioning device and trolley] Next, the connection operation between the positioning device 23 and the trolley 30 will be described. Figures 25A to 25D are explanatory diagrams showing the connection operation between the positioning device 23 and the trolley 30 according to the first embodiment. Figures 25A to 25D omit some parts from the illustration in order to make the operation of each part easier to understand.

[0123] Figure 25A shows the trolley 30 separated from the positioning device 23. In this state, when the operator pushes the trolley 30 and moves it in the connection direction (positive Y-axis direction), the trolley 30 enters between the pair of first positioning parts 230. At this time, the first roller 353 of the trolley 30 moves along the guide path 231a of the guide base 231 and then enters the first inclined surface 234 of the rail section 232.

[0124] As shown in Figure 25B, as this progresses, the first roller 353 receives a force in the height direction (Z-axis direction), causing the support base 35 to rise and the height adjustment section 36 to gradually extend. At this time, the second roller 354 enters the guide path 231a of the guide base 231.

[0125] Next, as shown in Figure 25C, when the first roller 353 reaches the boundary between the first inclined surface 234 and the second inclined surface 235, the support base 35 is in its highest position, and the height adjustment section 36 is also in its most extended position.

[0126] Next, as shown in Figure 25D, as the first roller 353 moves along the second inclined surface 235, the support base 35 gradually descends, and the height adjustment section 36 also gradually folds down. Finally, the first roller 353 comes into contact with the stopper 236 and stops.

[0127] In this manner, when the trolley 30 approaches the positioning device 23 from the negative Y-axis direction, the first roller 353 of the trolley 30 moves along the first inclined surface 234 of the rail section 232 and rides up onto it. Subsequently, the first roller 353 moves along the second inclined surface 235, descending and contacting the rail section 232, thereby restricting further movement. This restricts the position of the trolley 30 in the height direction (Z-axis direction) and the position in the positive Y-axis direction.

[0128] On the second inclined surface 235 of the first positioning section 230 in the positive X-axis direction, the first roller 353 enters between a pair of protrusions 237 (see Figure 24), thus restricting the position of the first roller 353 in the X-axis direction. In other words, the horizontal position is restricted by the stopper 236 and the pair of protrusions 237.

[0129] Furthermore, the positioning device 23 is provided with a rail-shaped second positioning section 315 that runs along the Y-axis. This second positioning section 315 is the part that positions the positioning roller 313 of the unit holding section 312. When the positioning roller 313 is guided by the second positioning section 315, the unit holding section 312 is positioned (see Figure 25D). In other words, the position of the unit holding section 312 relative to the component mounting device 20 is restricted.

[0130] [Movement of the roll body between the storage device and the receiving device] Next, the movement of the roll body 80 between the storage device 60 (first storage device 61 or second storage device 65) and the receiving device (first receiving device 38 or second receiving device 39) will be described. Here, the movement of the roll body 80 between the first storage device 61 and the first receiving device 38 will be illustrated, but the movement between the second storage device 65 and the second receiving device 39 is generally similar.

[0131] Figures 26A to 26C are explanatory diagrams showing the movement of the roll body 80 between the first storage device 61 and the first receiving device 38 according to the first embodiment. Figure 26A shows the state in which the leading edge of the carrier tape 83, which forms the roll body 80 to be stored in the first storage device 61, has begun to be fed out by the sprocket 314 of the feeder 311. As the carrier tape 83 is gradually pulled out from the roll body 80 from this state, the propulsion force causes the roll body 80 to move toward the first receiving device 38. Figure 26B shows the state in which the roll body 80 is in the process of moving. As the roll body 80 moves further, the first receiving device 38 receives the roll body 80. Figure 26C shows the state in which the roll body 80 has been received by the first receiving device 38.

[0132] The feeder 311 is equipped with a pair of sprockets 314 mounted coaxially. One sprocket 314 feeds out the carrier tape 83 unwound from the roll body 80 in the first receiving device 38, and the other sprocket 314 feeds out the carrier tape 83 unwound from the roll body 80 in the first storage device 61. Therefore, if there is still a roll body 80 remaining in the first receiving device 38, one sprocket 314 continues to feed out the carrier tape 83 from that roll body 80, and when that roll body 80 is depleted, the other sprocket 314 feeds out the carrier tape 83 from the roll body 80 in the first storage device 61. At this time, since the first receiving device 38 is empty, the roll body 80 in the first storage device 61 moves to the first receiving device 38, as shown in Figures 26A to 26C. Within the first receiving device 38, the carrier tape 83 is stably fed from the roll body 80 to the feeder 311. In other words, the first receiving device 38 is the feeding position of the roll body 80.

[0133] Incidentally, when the roll body 80 is moving, it may stop on its path due to some malfunction. A detection unit 403 (see Figure 27) is provided in the tape supply device 40 to determine if this stop is occurring.

[0134] [Detection unit] Next, the detection unit 403 will be described. Figure 27 is a schematic diagram showing the detection unit 403 according to the first embodiment. The detection unit 403 is an optical length measuring sensor. Examples of length measuring sensors are laser length measuring sensors and LED length measuring sensors. The detection unit 403 is positioned in the tape supply device 40 such that the movement path of the roll body 80 intersects its optical axis L. Specifically, when the first storage device 61 and the first receiving device 38 are held by the device holding unit 70, the optical axis L of the detection unit 403 is positioned with respect to the first movement path (an example of a movement path) of the roll body 80 moving between them. When the roll body 80 is stopped in the first movement path, the roll body 80 is on the optical axis L of the detection unit 403, so the detection result of the detection unit 403 is a first predetermined value (an example of a predetermined value). On the other hand, if the roll body 80 is not stopped in the first movement path, the roll body 80 is not on the optical axis L of the detection unit 403, and the detection unit 403 detects members below it, so the detection result of the detection unit 403 is greater than or equal to the first predetermined value.

[0135] Furthermore, when the second storage device 65 and the second receiving device 39 are held by the device holding unit 70, the optical axis L of the detection unit 403 is positioned relative to the second movement path (an example of a movement path) of the roll body 80 moving between them. When the roll body 80 is stopped in the second movement path, the roll body 80 is on the optical axis L of the detection unit 403, so the detection result of the detection unit 403 becomes the second predetermined value (an example of a predetermined value). On the other hand, when the roll body 80 is not stopped in the second movement path, the roll body 80 is not on the optical axis L of the detection unit 403, and the unit detects a member below it, so the detection result of the detection unit 403 becomes a value greater than or equal to the second predetermined value. In this way, by using the detection result of the detection unit 403, it is possible to determine whether or not the roll body 80 is stopped in the first or second movement path.

[0136] The detection unit 403 is mounted on the tape supply device 40 so as to be scannable in the X-axis direction, and this allows one detection unit 403 to detect the roll bodies 80 on each device holding unit 70. The number of detection units 403 can be any number; for example, multiple units may be provided so as to be one-to-one with each device holding unit 70.

[0137] [Control configuration of component mounting system] Next, the control configuration of the component mounting system 10 will be described. Figure 28 is a block diagram showing the control configuration of the component mounting system 10 according to the first embodiment. As shown in Figure 28, the component mounting system 10 includes a component mounting device 20, a trolley 30, a tape supply device 40, and a management computer 100, which are connected by a communication network, and the entire system is controlled by the management computer 100.

[0138] The component mounting device 20 comprises a head 21, a substrate transport unit 22, a communication unit 201, and a control unit 202 that controls these. The communication unit 201 is a communication module for communicating with the management computer 100, the tape supply device 40, and the trolley 30 wirelessly or via wired connection, and is freely connected to a communication network. The control unit 202 has a CPU, RAM, and ROM, and controls each part of the component mounting device 20 by having the CPU load programs from ROM into RAM and execute them. The control unit 202 may also control each part based on commands from the management computer 100.

[0139] The trolley 30 comprises each feeder 311, a communication unit 301, and a control unit 302 that controls them. The communication unit 301 is a communication module for communicating with the management computer 100, the tape supply device 40, and the component mounting device 20 wirelessly or via wired connection, and is freely connected to a communication network. The control unit 302 has a CPU, RAM, and ROM, and controls each part of the trolley 30 by having the CPU load a program from ROM into RAM and execute it. The control unit 302 may also control each part based on commands from the management computer 100. Each feeder 311 is provided with a rear end detection unit 311a that detects the rear end of the carrier tape 83 being supplied. When the rear end detection unit 311a detects the rear end of the carrier tape 83, it is detected that the roll body 80 in the receiving device is empty. Therefore, the feeder 311 winds up the carrier tape 83 of the next roll body 80 from the storage device corresponding to the receiving device and moves the next roll body 80 to the receiving device.

[0140] The tape supply device 40 includes a detection unit 403, a gripping unit 42, a tag reading unit 43, a supply unit 44, a retrieval unit 45, a notification unit 46, a moving unit 404, a communication unit 401, and a control unit 402 that controls these units.

[0141] The gripping unit 42 is the part that grips the gripped part 625 of the first storage device 61 or the second storage device 65. The tag reading unit 43 is a tag reader that reads the tag 626 provided on the gripped part 625 of the first storage device 61 or the second storage device 65. The supply unit 44 is the part that supplies the first storage device 61 or the second storage device 65 gripped by the gripping unit 42 to the device holding unit 70 of the trolley 30. The retrieval unit 45 is the part that retrieves the first storage device 61 or the second storage device 65 gripped by the gripping unit 42 from the device holding unit 70 of the trolley 30. The notification unit 46 is the part that provides various information visually or audibly. For example, a display device can be used as a notification unit 46 that provides visual notification, and a speaker can be used as a notification unit 46 that provides audible notification. The moving unit 404 is the part that scans the detection unit 403 in the X-axis direction. The communication unit 401 is a communication module that communicates with the management computer 100, the component mounting device 20, and the trolley 30 wirelessly or via wired connection, and is freely connected to the communication network. The control unit 402 has a CPU, RAM, and ROM, and controls each part of the tape supply device 40 by having the CPU load the program in ROM into RAM and execute it. The ROM stores a first predetermined value and a second predetermined value. The control unit 402 may also control each part based on commands from the management computer 100.

[0142] The control unit 402 determines whether the roll body 80 is stopped along its movement path based on the detection result of the detection unit 403. Specifically, the control unit 402 is an example of a determination unit that determines whether the distance to the object to be detected, as measured by the length measuring sensor (detection unit 403), is greater than or equal to a predetermined value. If the measured distance to the object to be detected is greater than or equal to the predetermined value, the control unit 402 determines that the roll body 80 is not stopped along its movement path. If the measured distance to the object to be detected is less than the predetermined value, the control unit 402 determines that the roll body 80 is stopped along its movement path and causes the notification unit 46 to notify an error. Note that even if the roll body 80 does not stop along its movement path, the detection result of the detection unit 403 will temporarily be greater than or equal to the predetermined value while it is moving along the path. Therefore, it is sufficient to determine that the roll body 80 has stopped along its movement path only when the detection result of the detection unit 403 remains greater than or equal to the predetermined value for a certain period of time or longer.

[0143] Here, the control unit 402 identifies which storage device 60 (first storage device 61 and second storage device 65) and receiving device (first receiving device 38 and second receiving device 39) the roll body 80 will move between, based on the information read by the tag reading unit 43 and the drive information of each feeder 311 obtained from the trolley 30 via the management computer 100. In other words, the control unit 402 controls the moving unit 404 to move the detection unit 403 to the space between the identified storage device 60 and receiving device. Furthermore, if the identified storage device 60 is the first storage device 61, the control unit 402 uses a first predetermined value to determine whether the roll body 80 has stopped midway, and if the identified storage device is the second storage device 65, it uses a second predetermined value to determine whether the roll body 80 has stopped midway.

[0144] If the control unit 402 does not determine that the roll body 80 should stop midway after it has moved, it determines that the identified storage device 60 is empty. Therefore, it controls the recovery unit 45 to recover the storage device 60, and then controls the supply unit 44 to supply a new storage device to the same location.

[0145] [effect] As described above, the storage device 60 (first storage device 61 and second storage device 65) stores a carrier tape 83 containing parts 87 and supplies the carrier tape 83 to a parts supply unit 31, and comprises a main body (first main body 63 and second main body 67) including storage sections (first storage section 62 and second storage section 66) having storage spaces (first storage space H1 and second storage space H2) for storing the carrier tape 83, a tape feeding section (first tape feeding section 93 and second tape feeding section 293), and a holding section (first holding section 94 and second holding section 294) that is provided on the main body so as to be movable between an extended position and a retracted position retracted from the extended position, and the tape feeding section feeds the leading edge of the carrier tape 83 to the parts supply unit 31 as the holding section moves back from the extended position.

[0146] Furthermore, there is a supply method for supplying a carrier tape 83 to a parts supply unit 31 using a supply device 60, wherein the supply device comprises a main body, a tape feeding unit, and a holding unit that is provided on the main body so as to be movable between an extended position and a retracted position moved back from the extended position and holds the tape feeding unit, and in the supply method, as the holding unit moves back from the extended position, the tape feeding unit sends the leading edge of the carrier tape to the parts supply unit.

[0147] According to these instructions, as the holding unit retracts from its extended position, the tape feeding unit sends the leading edge of the carrier tape 83 to the parts supply unit 31. Therefore, the carrier tape 83 can be sent to the parts supply unit 31 in conjunction with the retraction movement of the holding unit. Consequently, the insertion operation of the carrier tape 83 can be simplified.

[0148] Furthermore, the storage device 60 (first storage device 61 and second storage device 65) stores a carrier tape 83 containing parts 87 and supplies the carrier tape 83 to a parts supply unit 31, and includes a main body (first main body 63 and second main body 67) including storage sections (first storage section 62 and second storage section 66) having storage spaces (first storage space H1 and second storage space H2) for storing the carrier tape 83, a tape feeding section (first tape feeding section 93 and second tape feeding section 293) that moves toward the parts supply unit 31 to feed the leading edge of the carrier tape 83 to the parts supply unit 31, and a support section (first support section 942 and second support section 943) that supports the carrier tape 83, wherein the support section releases its support for the carrier tape 83 when the tape feeding section reaches a predetermined position.

[0149] According to this, when the tape feeding unit reaches a predetermined position, the support unit releases its support from the carrier tape 83, allowing the carrier tape 83 to be smoothly fed to the parts supply unit 31. Therefore, the insertion operation of the carrier tape 83 can be simplified.

[0150] Furthermore, the main body has a housing section (first housing section 64 and second housing section 68) that accommodates at least a part of the holding section in the retracted position.

[0151] According to this, at least a portion of the retaining part located in the retracted position is housed in the housing, so at least a portion of the retaining part can be protected by the housing.

[0152] Furthermore, the storage compartment is located below the storage compartment.

[0153] According to this, since the storage unit is located below the housing unit, the storage unit and the housing unit are aligned vertically. In other words, the storage unit and the housing unit do not overlap, so the storage device can be made thinner.

[0154] Furthermore, when the retaining portion is in the extended position, it protrudes more from the housing portion than when it is in the retracted position.

[0155] According to this, the retaining part in the extended position protrudes more from the storage part than when it is in the retracted position, making it easier to apply external force to the retaining part when retracting it to the retracted position. Therefore, the retraction operation can be performed smoothly, and the insertion work of the carrier tape 83, which is linked to the retraction operation, can be further simplified.

[0156] Furthermore, the retracted position is a position in which the tape feeding unit and the holding unit do not interfere with the carrier tape 83 that is pulled in by the parts supply unit 31.

[0157] According to this, the tape feeding unit and holding unit, which are located in the retracted position, do not interfere with the carrier tape 83 that is being pulled into the parts supply unit 31, so the carrier tape 83 can be pulled in smoothly.

[0158] Furthermore, the holding portion is slidable, swingable, or expandable in the direction of feeding the carrier tape 83, and the holding portion retracts from its extended position when a part of the holding portion is pressed against the parts supply unit 31.

[0159] According to this design, pressing a portion of the holding part against the parts supply unit 31 causes the holding part to retract from its extended position. As this retraction occurs, the tape feeding unit feeds the leading edge of the carrier tape 83 to the parts supply unit 31. In other words, the carrier tape 83 can be easily inserted into the parts supply unit 31 simply by pressing a portion of the holding part against the parts supply unit 31. Therefore, the insertion process for the carrier tape 83 can be simplified.

[0160] Furthermore, the holding part is biased in the feeding direction.

[0161] According to this, since the holding part is biased in the feeding direction, the holding part attempts to maintain its extended state. This maintains the initial position of the tape feeding part relative to the holding part.

[0162] Furthermore, the tape feeding unit has an engaging portion (claw portion 971) that engages with the feed hole 88 of the carrier tape 83, and when the tape feeding unit slides with the engaging portion engaged with the feed hole 88, the leading edge of the carrier tape 83 is fed to the parts supply unit 31.

[0163] According to this, with a simple structure in which the engaging part of the tape feeding unit engages with the feeding hole 88 of the carrier tape 83, the leading edge of the carrier tape 83 can be fed to the parts supply unit 31 by the sliding of the tape feeding unit.

[0164] Furthermore, the engaging portion slides diagonally downwards to diagonally upwards relative to the holding portion, thereby feeding the tip of the carrier tape 83 to the parts supply unit 31.

[0165] According to this, by simply pressing the holding part against the parts supply unit 31, the engaging part can be slid from diagonally downward to diagonally upward, thereby feeding the tip of the carrier tape 83 to the parts supply unit 31.

[0166] Furthermore, a portion of the holding part is the tip of the holding part.

[0167] According to this design, since a portion of the holding part is the tip of the holding part, it is easy to press a portion of the holding part against the parts supply unit 31. This makes it easy to perform the retraction movement of the holding part.

[0168] Furthermore, the tip of the holding portion has a contact portion 949 that is positioned by contacting the component supply unit 31.

[0169] According to this, the tip of the holding part is provided with a contact part 949 that is positioned by contacting the parts supply unit 31, and the holding part is positioned by this contact part 949. Therefore, it is possible to stably feed the carrier tape 83 to the parts supply unit 31.

[0170] Furthermore, the holding portion has a first support portion 942 that supports one end of the carrier tape 83 in the width direction and a second support portion 943 that supports the other end of the carrier tape 83 in the width direction, with the first support portion 942 facing the second support portion 943.

[0171] According to this, the first support portion 942 and the second support portion 943, which are opposite to each other, support the carrier tape 83 in the width direction, so that the carrier tape 83 can be stabilized when it is fed out.

[0172] Furthermore, the tape feeding unit has a support release member (second member 97) that releases the support of the carrier tape 83 by the first support part 942 and the second support part 943. The support release member moves between the first support part 942 and the second support part 943 as the tape feeding unit slides, thereby increasing the distance between the first support part 942 and the second support part 943 and releasing the support.

[0173] According to this, the support release member moves between the first support part 942 and the second support part 943 by the sliding of the tape feed part, thereby increasing the distance between the first support part 942 and the second support part 943 and releasing the support from the carrier tape 83. In other words, the support from the carrier tape 83 can be released in conjunction with the sliding of the tape feed part, making it possible to perform the release operation smoothly.

[0174] Furthermore, the storage section stores the roll body 80 of the carrier tape 83, and openings 623 and 663 for inserting and removing the roll body 80 are provided at the end of the storage section closest to the parts supply unit 31.

[0175] According to this, since openings 623 and 663 for inserting and removing the roll body 80 are provided at the end of the storage section closest to the parts supply unit 31, the roll body 80 can be smoothly moved from these openings 623 and 663 to the parts supply unit 31. In other words, such a storage device is suitable for a configuration in which the roll body 80 is moved between the storage section and the parts supply unit 31.

[0176] Furthermore, the storage section has a fall prevention section 624 that prevents the roll body 80 from falling out of the openings 623 and 663.

[0177] According to this, the fall prevention part 624 prevents the roll body 80 from falling out of the openings 623 and 663, thus preventing the roll body 80 from falling out of the openings 623 and 663 when transporting the storage device.

[0178] Furthermore, the fall prevention part 624 is provided to be movable between a prevention position that prevents the roll body 80 from falling and an allowable position that allows the roll body 80 to fall. When the storage device is not held by the trolley 30, the fall prevention part 624 is biased to be in the prevention position and moves from the allowable position to the second position by contacting a part of the trolley 30.

[0179] According to this, when the storage device is not held by the trolley 30, the fall prevention part 624 is biased to be in the prevention position. Therefore, before the storage device is held by the trolley 30, the fall prevention part 624 in the prevention position can prevent the roll body 80 from falling out. On the other hand, when the storage device is held by the trolley 30 and the fall prevention part 624 comes into contact with a part of the trolley 30 and moves from the prevention position to the allowable position, the fall of the roll body 80 is permitted. In other words, it becomes possible to move the roll body 80 to the parts supply unit 31.

[0180] The device also includes a tag 626 that stores information about the component 87 contained in the carrier tape 83.

[0181] According to this, the tag 626 provided in the storage device stores information about the component 87 stored in the carrier tape 83, so by reading the tag 626, the tape supply device 40 can be made to acquire information about the component 87.

[0182] Furthermore, the parts supply device (cart 30) has a parts supply unit 31 that supplies parts 87 by sending a carrier tape 83 containing parts 87 in the outward direction, and comprises a first device holding part (device holding part 70 in the first position) that holds a first storage device 61 that stores the carrier tape 83 in a first position, and a second device holding part (device holding part 70 in the second position) that stores a second storage device 65 that stores the carrier tape 83 and is smaller than the first storage device 61, and holds it in a second position.

[0183] According to this, the first storage device 61, which stores the carrier tape 83, is held by the first device holding section, and the second storage device 65, which stores the carrier tape 83 and is smaller than the first storage device 61, is held by the second device holding section. In other words, the relatively large first roll body 81 is stored in the first storage device 61, and the relatively small second roll body 82 is stored in the second storage device 65. This makes it possible to supply parts 87 simultaneously from multiple roll bodies 80 of different sizes.

[0184] Furthermore, the first storage device 61 is placed and held at the first position of the first device holding section, and the second storage device 65 is placed and held at the second position of the second device holding section, with the second position being higher than the first position.

[0185] According to this configuration, the first storage device 61 is placed in the first position, and the second storage device 65, which is smaller than the first storage device 61, is placed in the second position, which is higher than the first position. This reduces the height difference between the first storage device 61 and the second storage position 65. This improves handling when installing the first storage device 61 in the first position and the second storage device 65 in the second position. This is particularly suitable when the first storage device 61 and the second storage device 65 are supplied by the tape supply device 40.

[0186] Furthermore, the second device holding section holds the second storage device 65 and the second receiving device 39, which receives the second roll body 82 of the carrier tape 83, side by side along the feeding direction.

[0187] According to this, since the second device holding unit holds the second storage device 65 and the second receiving device 39 side by side in the delivery direction, the second roll body 82 pulled out from the second storage device 65 can be smoothly received by the second receiving device 39.

[0188] Furthermore, when the first storage device 61 is held in the first position and the second storage device 65 is held in the second position, the height of at least a portion of the upper surface 611 of the first storage device 61 is approximately equal to the height of at least a portion of the upper surface 651 of the second storage device 65, and in the delivery direction, the position of at least a portion of the base end surface 612 of the first storage device 61 is approximately equal to the position of at least a portion of the base end surface 652 of the second storage device 65.

[0189] According to this, when the first storage device 61 is held in the first position and the second storage device 65 is held in the second position, the height of at least a portion of the upper surface 611 of the first storage device 61 is approximately equal to the height of at least a portion of the upper surface 651 of the second storage device 65. In the same state, the position of at least a portion of the base end surface 612 of the first storage device 61 in the sending direction is approximately equal to the position of at least a portion of the base end surface 652 of the second storage device 65. In other words, on the trolley 30, the reference portion of the first storage device 61 (at least a portion of the upper surface 611 and at least a portion of the base end surface 612) and the reference portion of the second storage device 65 (at least a portion of the upper surface 651 or at least a portion of the base end surface 652) are positioned approximately equal to each other. Therefore, when setting the first storage device 61 in the first position and the second storage device 65 in the second position, the handling of the first storage device 61 and the second storage device 65, which are of different sizes, can be improved. This is preferable when the tape supply device 40 supplies the first storage device 61 and the second storage device 65 to the trolley 30.

[0190] Furthermore, the first storage device 61 has a first gripping portion (the gripping portion 625 of the first storage device 61) that is gripped, and at least a part of the upper surface 611 of the first storage device 61 is included in the first gripping portion. The second storage device 65 has a second gripping portion (the gripping portion 625 of the second storage device 65) that is gripped, and at least a part of the upper surface 651 of the second storage device 65 is included in the second gripping portion.

[0191] According to this, at least a portion of the upper surface 611 of the first storage device 61 is included in the first gripping portion, and at least a portion of the upper surface 651 of the second storage device 65 is included in the second gripping portion. In other words, the reference portion of the first storage device 61 is included in the first gripping portion, and the reference portion of the second storage device 65 is included in the second gripping portion, so that the reference portions which are arranged approximately equally are gripped. Therefore, it is possible to improve handling when gripping the first gripping portion to set the first storage device 61 in the first position, and when gripping the second gripping portion to set the second storage device 65 in the second position.

[0192] Furthermore, the device holder 70 is provided so as to be able to change its orientation between the first position and the second position.

[0193] According to this, since the device holder 70 is provided so as to be able to change its orientation between the first position and the second position, the orientation of the device holder 70 can be switched between the first position and the second position.

[0194] Furthermore, the trolley 30 is equipped with a fixing device 37 for fixing the device holding section 70 in the first or second position.

[0195] According to this, the fixing device 37 fixes the device holding part 70 in the first or second position, so the posture of the device holding part 70 can be stabilized by the fixing device 37.

[0196] The component mounting system 10 also includes a component supply unit 31 that supplies components 87 by sending a carrier tape 83 containing components 87, and a component mounting device 20 that mounts the components 87 supplied from the component supply unit 31 onto a substrate 50, wherein the component supply unit 31 is held by a trolley 30, the trolley 30 having a base 300 and a device holding part 70 that is provided to be vertically movable relative to the base 300 and holds a storage device 60 that stores the carrier tape 83, and the component mounting device 20 has a first positioning part 230 that positions the height of the device holding part 70 relative to the component mounting device 20.

[0197] Furthermore, the component mounting device 20, which mounts the component 87 onto the substrate 50, has a trolley 30 that holds a component supply unit 31 that supplies the component 87 by sending a carrier tape 83 containing the component 87, and the trolley 30 comprises a base 300 and a device holding section 70 that is provided to be vertically movable relative to the base 300 and holds a storage device 60 that stores the carrier tape 83, and the device holding section 70 is positioned by a first positioning section 230 provided on the component mounting device 20 to position its position in the height direction.

[0198] Furthermore, the component mounting device 20 mounts components 87 supplied by a component supply unit 31 held on a trolley 30 onto a substrate 50, wherein the trolley 30 has a base 300 and a device holding part 70 that holds a storage device 60 for storing a carrier tape 83 for storing components 87, which is provided to be vertically movable relative to the base 300, and the component mounting device 20 is provided with a first positioning part 230 that positions the height direction of the device holding part 70 relative to the component mounting device 20.

[0199] According to these findings, the first positioning unit 230 of the component mounting device 20 positions the device holding unit 70 in the height direction relative to the component mounting device 20, thereby improving the height-direction positioning accuracy between the trolley 30 and the component mounting device 20.

[0200] Furthermore, the first positioning unit 230 positions the device holding unit 70 in both the height and horizontal directions relative to the component mounting device 20.

[0201] According to this, the first positioning unit 230 positions the device holding unit 70 in the height and horizontal directions relative to the component mounting device 20, thereby improving the positioning accuracy of the trolley 30 and the component mounting device 20 in the height and horizontal directions.

[0202] Furthermore, the first positioning unit has a guide base that guides the height position of the device holding unit when the trolley is connected to the component mounting device, the trolley has rollers that move integrally with the device holding unit, and the rollers are guided by the guide base so as to ride on the guide base.

[0203] According to this, the rollers of the trolley 30 (first roller 353 and second roller 354) are guided by the guide base 231 of the first positioning unit 230 so that they ride up onto the guide base 231, thereby restricting the height position of the device holding unit 70. Therefore, even if there is vibration during position restriction, the trolley 30 is in a state where it is difficult to move, thus achieving stable positioning.

[0204] The roller also includes a first roller 353 and a second roller 354 aligned along the direction of connection of the trolley 30 to the parts mounting device 20, and the guide base 231 guides the first roller 353 and the second roller 354.

[0205] According to this, the guide base 231 guides the first roller 353 and the second roller 354 of the trolley 30, so that they can be smoothly guided by the rolling motion of the first roller 353 and the second roller 354.

[0206] Furthermore, the guide base 231 has an inclined surface (first inclined surface 234) on which the first roller 353 and the second roller 354 ride when the trolley 30 is connected to the parts mounting device 20.

[0207] According to this, since the guide base 231 is provided with an inclined surface on which the first roller 353 and the second roller 354 ride, they can smoothly ride up the inclined surface through the rolling motion of the first roller 353 and the second roller 354.

[0208] Furthermore, the trolley 30 has a height adjustment section 36 that adjusts the height of the device holding section 70 relative to the component mounting device 20 by contacting the roller guide base 231 and receiving a force in the height direction from the component mounting device 20.

[0209] According to this, the height adjustment unit 36 ​​adjusts the height of the device holding unit 70 relative to the component mounting device 20 by receiving a force in the height direction from the component mounting device 20 when the roller contacts the guide base 231, so the height of the device holding unit 70 can be adjusted independently by the height adjustment unit 36.

[0210] Furthermore, the trolley 30 is provided so as to be able to move up and down relative to the base 300 and has a unit holding part 312 for holding the parts supply unit 31, and the parts mounting device 20 has a second positioning part 315 for positioning the unit holding part 312 relative to the parts mounting device 20.

[0211] According to this, the second positioning unit 315 positions the unit holding unit 312 relative to the component mounting device 20, thereby improving the positioning accuracy between the unit holding unit 312 and the component mounting device 20.

[0212] Furthermore, the component mounting system 10 includes a component supply device (cart 30) for supplying components 87, a tape supply device 40 that supplies a storage device 60 for storing the roll body 80 of the carrier tape 83 to the component supply device, and a component mounting device 20 that mounts the components 87 supplied by the component supply device onto the substrate 50. The component supply device includes a component supply unit 31 that pulls in the carrier tape 83 containing the components 87 and supplies the components 87, a device holding unit 70 that detachably holds the storage device 60, and receiving devices (first receiving device 38 and second receiving device 39) that receive the roll body 80 that has moved from the storage device 60 due to the pull-in of the component supply unit 31. The tape supply device 40 has a detection unit 403 that detects the roll body 80 along the movement path of the roll body 80 from the storage device 60 to the receiving device.

[0213] Furthermore, the tape supply device 40 supplies a storage device 60 for storing the roll body 80 of the carrier tape 83 to a parts supply device that supplies parts 87, wherein the parts supply device comprises a device holding unit 70 that detachably holds the storage device 60 and a receiving device that receives the roll body when it moves from the storage device 60 due to the pull-in of the parts supply device, and the tape supply device 40 has a detection unit 403 that detects the roll body 80 along the movement path of the roll body 80 from the storage device 60 to the receiving device.

[0214] According to these findings, the detection unit 403 detects the roll body 80 along its movement path, and based on the detection result of the detection unit 403, it is possible to determine whether or not the roll body 80 is stopped along its movement path. Therefore, if it is determined that the roll body 80 is stopped along its movement path, an appropriate action can be taken.

[0215] Furthermore, the detection unit 403 is an optical sensor, and the optical axis L of the optical sensor intersects the movement path of the roll body 80 as it moves between the storage device and the receiving device.

[0216] According to this, since the optical axis L of the optical sensor intersects with the movement path of the roll body 80 moving between the storage device and the receiving device, it is possible to easily detect when the roll body 80 has stopped in the middle of its movement path using the optical sensor.

[0217] Furthermore, optical sensors are length-measuring sensors.

[0218] According to this, since the optical sensor is a length-measuring sensor, it is possible to easily detect the stopping of the roll body 80 without using a camera or the like.

[0219] Furthermore, the tape supply device 40 includes a determination unit (control unit 402) that determines whether the distance to the object to be detected, as measured by the length measuring sensor, is greater than or equal to a predetermined value, and a notification unit 46 that notifies an error if it is determined that the distance is not greater than or equal to a predetermined position.

[0220] According to this, if the judgment unit determines that the distance to the object to be detected, as measured by the length measuring sensor, is not equal to or greater than a predetermined value, the notification unit 46 will notify the operator of the stoppage of the roll body 80. This makes it possible to respond quickly to the stoppage of the roll body 80.

[0221] Furthermore, the tape supply device 40 has a recovery unit 45 that recovers an empty storage device 60 from the parts supply device when it is determined that the distance is greater than a predetermined position.

[0222] According to this, if the determination unit determines that the distance is greater than a predetermined position, the retrieval unit 45 retrieves the empty storage device 60 from the parts supply device, so that the empty storage device 60 can be retrieved while the roll body 80 is not stopped. In other words, it is possible to prevent the stopped roll body 80 from getting in the way while the empty storage device 60 is being retrieved.

[0223] Furthermore, the predetermined value varies depending on the size of the storage device 60 or the outer diameter of the roll body 80.

[0224] According to this, the predetermined value differs depending on the size of the storage device 60 or the outer diameter of the roll body 80, so an appropriate predetermined value is set for each storage device 60 of different sizes or roll body 80 of different outer diameters. This makes it possible to reliably determine when to stop a roll body 80 of different sizes.

[0225] Furthermore, the parts supply system (parts mounting system 10) includes a supply device (first storage device 61 and second storage device 65) that supplies the carrier tape 83 to the parts supply unit 31, and a position change unit (sprocket 314). The supply device has a main body (first main body 63 and second main body 67), a tape feeding unit (first tape feeding unit 93 and second tape feeding unit 293) that sends the leading edge of the carrier tape 83 to the parts supply unit 31, and a holding unit (first holding unit 94 and second holding unit 294) that holds the tape feeding unit. The holding unit is provided on the main body so as to be movable between an extended position and a retracted position. The position change unit moves the holding unit from the extended position to the retracted position by contacting the holding unit.

[0226] According to this, the repositioning unit moves the holding unit from the extended position to the retracted position by contacting the holding unit, so that the holding unit can be positioned in the retracted position. In a supply device, the retracted position is a position where the holding unit does not protrude beyond the extended position, so if the holding unit is positioned in the retracted position, the supply device can be made smaller. As the supply device can be made smaller in this way, it is possible to miniaturize the entire parts supply system.

[0227] Furthermore, the position change section is provided in the parts supply unit 31, the trolley 30 that holds the parts supply unit 31, or the tape supply device 40 that supplies the supply device to the trolley 30.

[0228] According to this, since the position-changing section is provided in the parts supply unit 31, the trolley 30, or the tape supply device 40, the position-changing section can be standardized across the parts supply unit 31, the trolley 30, or the tape supply device 40. In other words, it is not necessary to provide a dedicated position-changing section, so the entire parts supply system can be made more compact.

[0229] Furthermore, the holding portion moves from the extended position to the retracted position when its tip is pressed against the position-changing portion.

[0230] According to this, the holding part can be moved from the extended position to the retracted position with a simple action of pressing the tip of the holding part against the position change part.

[0231] Furthermore, the holding portion is slidable, swingable, or expandable in the direction of feeding the carrier tape 83.

[0232] According to this, even when the holding part is slidable, swingable, or expandable in the feeding direction of the carrier tape 83, the entire component supply system can be made smaller.

[0233] Furthermore, the supply device has a state-holding part (leaf spring 621a) that holds the holding part in the retracted position.

[0234] According to this design, the holding part, which is located in the retracted position, is held by the state-holding part, thus allowing the holding part to be maintained in the retracted position. This makes it possible to maintain a compact state-of-the-art supply device.

[0235] Furthermore, the main body has a storage section equipped with a storage space for storing the carrier tape 83.

[0236] According to this, even in the case of a supply device with a storage compartment, the holding part can be positioned in a retracted position, thus making the supply device more compact.

[0237] Further, the cart 30 includes a restricting portion (switching member 79) that restricts movement of the storage device.

[0238] According to this configuration, since the restricting portion restricts movement of the storage device, positional displacement of the storage device can be suppressed.

[0239] (Second Embodiment) In the first embodiment described above, the case where the tape feeder 40 includes the detection unit 403 and the moving unit 404 is exemplified. However, the detection unit and the moving unit may be provided on the cart.

[0240] FIG. 29 is a block diagram showing a control configuration of a component mounting system 10A according to the second embodiment. In the following description, portions different from the first embodiment will be described, and identical portions may be denoted by the same reference symbols and description thereof may be omitted.

[0241] As shown in FIG. 29, in a component mounting system 10A according to another embodiment, the detection unit and the moving unit are omitted from a tape feeder 40A, and a detection unit 303 and a moving unit 304 are provided on a cart 30A. The cart 30A is an example of a component feeder.

[0242] The detection unit 303 is basically equivalent to the detection unit 403, but differs in that it is installed on the cart 30A. The detection unit 303 is an optical length measurement sensor, and is disposed on the cart 30A such that the movement path of the roll body 80 is positioned on the optical axis thereof. The moving unit 304 is basically equivalent to the moving unit 404, but differs in that it is installed on the cart 30A. The detection unit 303 and the moving unit 304 are controlled by a control unit 302 of the cart 30A. The control unit 302 determines whether the roll body 80 is stopped in the middle of the movement path based on a detection result of the detection unit 303.

[0243] As described above, the component mounting system 10A includes: a component supply device (cart 30A) that supplies a component 87; a tape supply device 40 that supplies, to the component supply device, a storage device 60 that stores a roll 80 of carrier tape 83; and a component mounting device 20 that mounts the component 87 supplied by the component supply device onto a substrate 50. The component supply device includes: a component supply unit 31 that pulls in a carrier tape 83 storing the component 87 to supply the component 87; a device holding portion 70 that detachably holds the storage device 60; a receiving device (a first receiving device 38 and a second receiving device 39) that receives the roll 80 moved from the storage device 60 by the pulling-in of the component supply unit 31; and a detection unit 303 that detects the roll 80 in the middle of a movement path of the roll 80 from the storage device 60 to the receiving device.

[0244] The present invention also relates to a component supply device (cart 30A) that supplies a component 87, the component supply device including: a device holding portion 70 that detachably holds a storage device 60 that stores a roll 80 of carrier tape 83; a component supply unit 31 that pulls in a carrier tape 83 storing the component 87 to supply the component 87; a receiving device (a first receiving device 38 and a second receiving device 39) that receives the roll 80 moved from the storage device 60 by the pulling-in of the component supply unit 31; and a detection unit 303 that detects the roll 80 in the middle of a movement path of the roll 80 from the storage device 60 to the receiving device.

[0245] According to these configurations, since the detection unit 303 detects the roll 80 in the middle of the movement path of the roll 80, it can be determined whether or not the roll 80 has stopped in the middle of the movement path based on the detection result of the detection unit 303. Therefore, when it is determined that the roll 80 has stopped in the middle of the movement path, it is possible to take measures against such a situation.

[0246] Further, the component supply device includes a moving portion 304 that moves the detection unit 303 in an arrangement direction of the plurality of device holding portions 70.

[0247] According to this, the parts supply device has a moving unit 304 that moves the detection unit 303 in the direction of the arrangement of the multiple device holding units 70, so that a single detection unit 303 can detect a roll body 80 that has stopped along the moving path to each device holding unit 70.

[0248] Furthermore, the detection unit for detecting the roll body along the movement path can be located anywhere within the component mounting system. In other words, the detection unit may be located anywhere other than the tape supply device or the trolley. The same applies to the moving part.

[0249] (Third embodiment) In the first embodiment described above, we illustrated the case in which only the second support portion 943 is elastically deformed when the carrier tape 83 is fed out. In this third embodiment, we will describe the case in which the first support portion is also elastically deformed.

[0250] Figure 30 is an exploded perspective view showing the first tape feeding unit 93b and the first holding unit 94 according to a third embodiment. As shown in Figure 30, the first tape feeding unit 93b further comprises a fourth member 99. The fourth member 99 is positioned in the X-axis positive direction of the holding body 941b. Here, in the holding body 941, a guide groove 945b penetrates through the entire length in the X-axis direction.

[0251] The fourth member 99 is a long plate in the Y-axis direction, tapering towards the tip in the Y-axis positive direction. A projection 992 protruding in the X-axis positive direction is formed at the lower center of the fourth member 99. Two through-holes 994 and 995 are formed in the fourth member 99. The through-holes 994 and 995 are arranged at an inclination in the Y-axis direction. Bosses 974b and 975b attached to the second member 97 are mounted to the through-holes 994 and 995 via guide grooves 945b. As a result, the fourth member 99 slides in the Y-axis direction relative to the holding body 941b together with the second member 97.

[0252] Figure 31A is a bottom view showing the state in which the support pieces 954 of the first support portion 942 and the second support portion 943 support the carrier tape 83 according to the third embodiment. Figure 31B is a bottom view showing the state in which the support of the carrier tape 83 by the support pieces 954 of the first support portion 942 and the second support portion 943 has been released according to the third embodiment. The carrier tape 83 is not shown in Figures 31A and 31B.

[0253] As shown in Figure 31A, in this state, the projection 972 of the second member 97 is not in contact with the support piece 954 of the second support portion 943, and the projection 992 of the fourth member 99 is not in contact with the support piece 954 of the first support portion 942. In other words, the first support portion 942 and the second support portion 943 are not elastically deformed, and the distance H between the lower ends of each support piece 954 is narrower than the width of the carrier tape 83. The tip of the carrier tape 83 rests on and is supported on the lower ends of each support piece 954.

[0254] As the feed progresses, the second member 97 and the fourth member 99 slide in the positive Y-axis direction. As a result, the projection 972 of the second member 97 contacts the support piece 954 of the second support part 943, causing the second support part 943 to elastically deform, and the projection 992 of the fourth member 99 contacts the support piece 954 of the first support part 942, causing the first support part 942 to elastically deform. As a result, the distance H between the lower ends of each support piece 954 becomes wider than the width of the carrier tape 83, and the support for the carrier tape 83 is released.

[0255] (Fourth embodiment) In the fourth embodiment, a modified example of the device holding portion will be described. Figure 32 is a plan view showing the device holding portion 70c in the first position according to the fourth embodiment. Figure 33 is a plan view showing the device holding portion 70c in the second position according to the fourth embodiment.

[0256] As shown in Figures 32 and 33, the device holder 70c according to the fourth embodiment differs from the device holder 70 according to the first embodiment in that it has only one leg portion 72c. The leg portion 72c has an upper limb 721c and a lower limb 722c. One end of the upper limb 721c rotatably supports the mounting portion 71. The other end of the lower limb 722c is rotatably supported by the support base 35. The other end of the upper limb 721c and one end of the lower limb 722c are rotatably connected. As a result, the upper limb 721c and the lower limb 722c are foldable.

[0257] As shown in Figure 32, when the device holding section 70c is in the first position, the first storage device 61 is placed on the mounting section 71 and is held in the first position.

[0258] As shown in Figure 33, when the device holder 70c is in the second position, a position-regulating block 790 is installed between the mounting section 71 and the support base 35. The mounting section 71 is supported by this regulating block 790, so that the second position of the device holder 70c is maintained. In the second position, the second storage device 65 is placed on the mounting section 71 and is held in the second position.

[0259] In this case as well, the upper surfaces 611 and 651 of the first storage device 61 held in the first position and the second storage device 65 held in the second position are approximately equal to a first reference plane parallel to the XY plane, and the base end surfaces 612 and 652 of the first storage device 612 and 652 are approximately equal to a second reference plane parallel to the XZ plane.

[0260] Thus, as long as the first storage device 61 can be held in the first position and the second storage device 65 can be held in the second position, the configuration of the device holding part can be anything. For example, the device holding part does not need to move up or down.

[0261] FIG. 34A is a schematic diagram showing a state where a first storage device 61 is held by a device holding portion 70d according to a modified example of the fourth embodiment. As shown in FIG. 34A, the device holding portion 70d has only a mounting portion 71 fixed to a support base 35. The first storage device 61 and a first receiving device 38 are mounted on the mounting portion 71. Accordingly, the first storage device 61 is held at a first position.

[0262] FIG. 34B is a schematic diagram showing a state where a second storage device 65 is held by the device holding portion 70d according to the modified example of the fourth embodiment. In this case, a height-raising block 791 for height raising is attached to the mounting portion 71, and the second storage device 65 and a second receiving device 39 are mounted on the height-raising block 791. Accordingly, the second storage device 65 is held at a second position.

[0263] (Fifth Embodiment) In the first embodiment, the sprocket 314 of the feeder 311 is a position changing portion that moves the holding portion of the storage device from the advanced position to the retracted position. In this case, the position of the sprocket 314 is fixed, and the holding portion is moved from the advanced position to the retracted position by pressing the storage device against the sprocket 314. In the fifth embodiment, a case where the holding portion is moved from the advanced position to the retracted position by driving the position changing portion will be described.

[0264] FIG. 35A is a plan view showing a state immediately after a position changing portion 500 according to the fifth embodiment contacts a first holding portion 94. FIG. 35B is a plan view showing a state where the position changing portion 500 according to the fifth embodiment moves the first holding portion 94 to the retracted position.

[0265] As shown in Figures 35A and 35B, the repositioning unit 500 is located near the feeder 311 and is reciprocated in the Y-axis direction by the drive unit 510. The repositioning unit 500 and the drive unit 510 are installed in either the parts supply unit 31, the trolley 30, or the tape supply device 40. The drive unit 510 is a drive source such as a motor or solenoid and is connected to the repositioning unit 500 via a power transmission mechanism (not shown). The driving force of the drive unit 510 causes the repositioning unit 500 to reciprocate in the Y-axis direction. The drive unit 510 is controlled by a control unit provided in the device it is installed in, or by a management computer 100.

[0266] As shown in Figure 35A, when the tape supply device 40 moves the first storage device 61 and the first holding part 94 comes into contact with the position change part 500, the tape supply device 40 maintains that state. At this time, the first holding part 94 is in the extended position. Subsequently, as shown in Figure 35B, the drive unit 510 moves the position change part 500 in the negative Y-axis direction, pushing in the first holding part 94 and moving it from the extended position to the retracted position.

[0267] Thus, the parts supply system further includes a drive unit 510 that drives a position changing unit 500 to move the holding unit from an extended position to a retracted position.

[0268] According to this, the holding unit can be moved from the extended position to the retracted position by driving the position changing unit 500 with the drive unit 510 without having to move the supply device.

[0269] As described above, the tape supply device may be provided with a position change unit 500. That is, a tape supply device that supplies a supply device to a trolley that holds a supply device that supplies a carrier tape to a parts supply unit, wherein the supply device has a main body, a tape feeding unit that sends the leading edge of the carrier tape to the parts supply unit, and a holding unit that holds the tape feeding unit, the holding unit is provided on the main body so as to be movable between an extended position and a retracted position which is retracted from the extended position, and the tape supply device has a position change unit that moves the holding unit from the extended position to the retracted position by contacting the holding unit.

[0270] According to this, the position-changing unit in the tape supply device moves the holding unit from the extended position to the retracted position by contacting the holding unit, so that the holding unit can be positioned in the retracted position. In the supply device, the retracted position is a position where the holding unit does not protrude beyond the extended position, so if the holding unit is positioned in the retracted position, the supply device can be made smaller. As the supply device can be made smaller in this way, it is possible to miniaturize the supply device and the entire component supply system having the tape supply device.

[0271] Furthermore, as described above, a trolley 30, which is an example of a parts supply device, may be provided with a position change unit 500. In other words, a parts supply device that supplies a carrier tape to a parts supply unit and a parts supply device that holds the parts supply unit, wherein the supply device has a main body, a tape feeding unit that sends the leading edge of the carrier tape to the parts supply unit, and a holding unit that holds the tape feeding unit, the holding unit is provided on the main body so as to be movable between an extended position and a retracted position which is retracted from the extended position, and the parts supply device has a position change unit that moves the holding unit from the extended position to the retracted position by contacting the holding unit.

[0272] According to this, the position-changing unit in the parts supply device moves the holding unit from the extended position to the retracted position by contacting the holding unit, so that the holding unit can be positioned in the retracted position. In the supply device, the retracted position is a position where the holding unit does not protrude beyond the extended position, so if the holding unit is positioned in the retracted position, the supply device can be made smaller. As the supply device can be made smaller in this way, it is possible to miniaturize the entire parts supply system, which includes a parts supply device and a tape supply device.

[0273] (Sixth Embodiment) In the first embodiment, an example was given in which the first tape feeding unit 93 and the first holding unit 94 are slidable in the Y-axis direction. In the sixth embodiment, a case in which the first tape feeding unit 93e and the first holding unit 94e are rotatable will be described.

[0274] Figure 36A is a plan view showing the state immediately after the position-changing part 500e according to the sixth embodiment comes into contact with the first holding part 94e. Figure 36B is a plan view showing the state after the position-changing part 500e according to the sixth embodiment has moved the first holding part 94e to the retracted position.

[0275] As shown in Figures 36A and 36B, the first retaining portion 94e is rotatably mounted on the first main body portion 63e, with the end opposite to the tip of the first retaining portion 94e as its center. A slit portion 959e is formed on the upper part of the first retaining portion 94e, with the tip end of the first retaining portion 94e being open. The position changing portion 500e is driven after entering the slit portion 959e, causing the first retaining portion 94e to rotate.

[0276] As shown in Figure 36A, when the first holding unit 94e maintains a horizontal position, the first holding unit 94e and the first tape feeding unit 93e are positioned in the extended position. In this state, when the first holding unit 94e is rotated by the position changing unit 500e, the first holding unit 94e and the first tape feeding unit 93e are moved to the retracted position, as shown in Figure 36B.

[0277] Thus, the holding portion (first holding portion 94e) is rotatably mounted on the main body portion (first main body portion 63e) with respect to the end opposite to the tip of the holding portion.

[0278] According to this, even when the holding part is rotatably mounted relative to the main body, the entire parts supply system can be made smaller.

[0279] (Seventh Embodiment) In the seventh embodiment, a preferred detachment operation for detaching the first tape feed unit 93 from the carrier tape 83 engaged with the sprocket 314 will be described. Figure 37 is an explanatory diagram showing the detachment operation of the first tape feed unit 93 according to the seventh embodiment. In Figure 37, the first tape feed unit 93 after detachment is shown by a dashed line. The subsequent detachment operation of the first tape feed unit 93 is achieved by the tape supply device 40 moving the first storage device 61. Furthermore, the detachment operation is initiated by the tape supply device 40 based on a detection signal from a sensor that detects that a pair of claws 971 have engaged with the feed holes 88 of the carrier tape 83. In other words, the detachment operation starts after the leading edge of the carrier tape 83 has been fed to the component supply unit 31.

[0280] When disengaging the first tape feed unit 93 from the carrier tape 83 engaged with the sprocket 314, it is possible to do so simply by moving the pair of claws 971 of the first tape feed unit 93 in the negative Y-axis direction. However, in this case, the pair of claws 971 may get caught in the feed holes 88 of the carrier tape 83, preventing smooth disengagement. To suppress this, there are first and second disengagement operations.

[0281] The first detachment operation, as shown in Figure 37, involves raising a pair of claw portions 971 and then moving them in the negative direction of the Y-axis. The pair of claw portions 971 disengage from the feed hole 88 when raised. When raised, they should be raised within a range of 1 mm to 1.5 mm. In this way, after the leading edge of the carrier tape 83 is fed to the parts supply unit 31, each claw portion 971 (engaging portion) rises to disengage from the feed hole 88 and moves away from the parts supply unit 31.

[0282] According to this, by raising the pair of claw portions 971, they can be smoothly detached from the feed holes 88 of the carrier tape 83.

[0283] The second detachment operation involves moving the pair of claw portions 971 diagonally upward in the negative Y-axis direction. In this way, after the leading edge of the carrier tape 83 is fed to the parts supply unit 31, each claw portion 971 (engaging portion) moves diagonally backward and upward to disengage from the feed hole 88 and move away from the parts supply unit 31.

[0284] According to this, by moving the pair of claw portions 971 diagonally upward and backward, they can be smoothly detached from the feed hole 88 of the carrier tape 83.

[0285] Furthermore, to improve the straightness of the carrier tape 83's feed, there may be three or more claw portions 971.

[0286] (Eighth embodiment) In the eighth embodiment, a structure for suppressing misalignment between the storage device and the receiving device will be described. Here, the first storage device 61f is given as an example of a storage device, and the first receiving device 38 is given as an example of a receiving device, but similar structures may be adopted for the second storage device and the second receiving device.

[0287] Figure 38 is a plan view showing the lower structure of the first storage device 61f according to the eighth embodiment. As shown in Figure 38, an expansion member 690f is attached to the lower part of the first storage device 61f, which is wider (in length in the X-axis direction) than the pair of first cover bodies 622. The expansion member 690f is provided at the end of the first storage device 61f on the opening 623 side (the end in the positive Y-axis direction). The expansion member 690f has a fitting portion 691f that fits between the pair of first cover bodies 622, and a protrusion 692f that is continuous with the fitting portion 691f and protrudes from the pair of first cover bodies 622 in the positive Y-axis direction. The protrusion 692f has a trapezoidal shape that tapers outward on both sides in the X-axis direction. In other words, a pair of guide surfaces 693f are formed at the lower part of the protrusion 692f, which are inclined so as to widen in the negative Y-axis direction. The maximum thickness t1 of the protrusion 692f is greater than the spacing t2 of the opening 623.

[0288] Next, the installation method for the first storage device 61f being installed on the first receiving device 38 will be described. Figures 39A to 39D are perspective views showing the operation when the first storage device 61f according to the eighth embodiment is installed on the first receiving device 38. Figures 40A to 40D are plan views showing the operation when the first storage device 61f according to the eighth embodiment is installed on the first receiving device 38. Figures 39A and 40A correspond to each other, Figures 39B and 40B correspond to each other, Figures 39C and 40C correspond to each other, and Figures 39D and 40D correspond to each other. These correspond to the operations from Figure 15B to Figure 15C described above.

[0289] Figures 39A and 40A show the state immediately after the first storage device 61f has begun to descend and is separated from the first receiving device 38. Here, the first receiving device 38 has a pair of plate-shaped second cover bodies 383 that form part of the outer casing of the first receiving device 38. The second cover bodies 383 are an example of a cover body. The pair of second cover bodies 383 are spaced apart in the X-axis direction (thickness direction), and this spacing constitutes an opening 381 (second opening). The opening 381 leaves open the Z-axis positive end and the Y-axis negative end of the first receiving device 38.

[0290] When the first storage device 61f is separated from the first receiving device 38, the pair of second cover bodies 383 are not elastically deformed. At this time, the distance t3 (distance of the opening 381) between the pair of second cover bodies 383 is smaller than the maximum thickness t1 of the protrusion 692f of the first storage device 61f.

[0291] Figures 39B and 40B show the state immediately after the first storage device 61f begins to engage with the first receiving device 38. Figures 39C and 40C show the state as the descent progresses and the first storage device 61f is engaged with the first receiving device 38 to some extent. In this way, as the first storage device 61f descends, the protrusion 692f of the expansion member 690f enters into the pair of second cover bodies 383 of the first receiving device 38. At this time, each guide surface 693f of the expansion member 690f elastically deforms while guiding each second cover body 383. As a result, the distance t3 between each second cover body 383 is smoothly widened, and the distance t3 of the opening 381 is expanded.

[0292] Figures 39D and 40D show the first storage device 61f installed in the first receiving device 38. In this state, the protrusion 692f of the expansion member 690f passes through the pair of second cover bodies 383 of the first receiving device 38. As a result, the elastic deformation of the pair of second cover bodies 383 is released and they return to their original state. At this time, at least a part of the first storage device 61f is located inside the opening 381.

[0293] Thus, the component mounting system comprises a component supply device (cart 30) that supplies component 87, and a component mounting device 20 that mounts the component 87 supplied by the component supply device onto a substrate 50. The component supply device comprises a component supply unit 31 that pulls in a carrier tape 83 that stores component 87 and supplies component 87, a storage device (first storage device 61f) that has a first opening (opening 623) through which the roll body 80 of the carrier tape 83 passes and stores the roll body 80, and a receiving device (first receiving device 38) that has a second opening (opening 381) and receives the roll body 80 that has moved from the first opening due to the pull-in of the component supply unit 31. The storage device has an expansion member 690f that expands the distance t3 of the second opening in the thickness direction of the receiving device when the storage device is installed relative to the receiving device.

[0294] Furthermore, the installation method involves installing a storage device, which has a first opening through which a roll body 80 of the carrier tape 83 passes and which stores the roll body, relative to a receiving device, which has a second opening for receiving the roll body 80. When the storage device is installed relative to the receiving device, the storage device expands the distance t3 between the second openings in the thickness direction of the receiving device.

[0295] According to these findings, when the storage device is installed in the receiving device, the expansion member 690f expands the spacing t3 of the second opening in the receiving device, making it easier to install the storage device within the expanded second opening. This helps to suppress misalignment between the storage device and the receiving device.

[0296] Furthermore, the expansion member 690f is provided at the end of the storage device on the first opening side, and the receiving device has a pair of cover bodies (second cover body 383) that form a second opening and are provided with a gap t3 in the thickness direction, and when the storage device is installed relative to the receiving device, the expansion member 690f contacts the pair of cover bodies from the inside and widens the gap t3.

[0297] According to this, the expansion member 690f contacts the pair of cover bodies constituting the second opening from the inside of the pair of cover bodies to widen the gap t3, which allows for a simpler configuration than when the gap t3 between the pair of cover bodies is widened from the outside.

[0298] The thickness (maximum thickness t1) of the portion of the expansion member 690f that contacts the pair of cover bodies (protrusion 692f) is greater than the distance t3 before contact.

[0299] According to this, since the thickness of the portion of the expansion member 690f that contacts the pair of cover bodies is greater than the distance t3 before contact, the distance t3 can be widened simply by bringing the contact portion of the expansion member 690f into contact with the inside of the pair of cover bodies.

[0300] Furthermore, the thickness of the portion of the expansion member 690f that contacts the pair of cover bodies may be greater than the spacing t2 in the thickness direction of the opening 623.

[0301] According to this, since the thickness of the portion of the expansion member that contacts the pair of cover bodies is greater than the distance t2 in the thickness direction of the first opening, the distance t3 between the pair of cover bodies can be reliably widened to greater than the distance t2 between the first opening simply by bringing the contact portion of the expansion member into contact with the inside of the pair of cover bodies.

[0302] Furthermore, when the storage device is installed relative to the receiving device, at least a portion of the storage device is located inside the second opening.

[0303] According to this, at least a portion of the storage device is located inside the second opening, so the storage device is positioned by the second opening. Therefore, misalignment between the storage device and the receiving device can be further suppressed.

[0304] (Ninth Embodiment) In the first embodiment, a switching member 79 formed from a block was described as an example of a limiting portion. However, the limiting portion may take any form as long as it can restrict the movement of the storage device. In the ninth embodiment, a modified example of the limiting portion will be described. Figures 41A and 41B are perspective views showing the limiting portion 79g according to the ninth embodiment. Figure 41A shows the first storage device 61g separated from the device holding portion 70g, and Figure 41B shows the first storage device 61g held by the device holding portion 70g.

[0305] The device holding portion 70g is formed from sheet metal, and a portion of the portion corresponding to each first storage device 61g is cut and bent to form a limiting portion 79g. The limiting portion 79g is a plate-shaped projection with a bent tip. As shown in Figure 41A, when the first storage device 61g is separated from the device holding portion 70g, the limiting portion 79g is not inserted into the insertion portion 619g of the first storage device 61g. Therefore, the fall prevention portion 624 is in the fall prevention ON state. Subsequently, when the first storage device 61g descends and is held by the device holding portion 70g, the limiting portion 79g is inserted into the insertion portion 619g. As a result, the limiting portion 79g comes into contact with the second support column 628 of the fall prevention portion 624, and the second support column 628 is pushed down. As a result, the first support column 627 also falls over, and the fall prevention portion 624 is in the fall prevention OFF state. Here, the insertion portion 619g of the first storage device 61g is a through-hole that penetrates in the Z-axis direction, and the end in the Y-axis positive direction is closed. In other words, the limiting portion 79g can restrict the movement of the first storage device 61g in the Y-axis direction as well as the X-axis direction.

[0306] (others) Although a component mounting system 10 according to an embodiment of the present invention has been described above, the present invention is not limited to this embodiment. In other words, the embodiments disclosed herein are illustrative in all respects, and the scope of the present invention includes all modifications in the sense and scope equivalent to the claims.

[0307] For example, in the first embodiment described above, the contact portion 949 is shown as being formed in a groove shape, but the shape of the contact portion can be anything as long as it is positioned by contacting the parts supply unit. For example, a groove may be provided on the parts supply unit side, and the contact portion may be made into a convex shape that fits into the groove.

[0308] Furthermore, in the first embodiment described above, an example was given in which at least a portion of the upper surface 611 of the first storage device 61 is included in the first gripping portion, and at least a portion of the upper surface 651 of the second storage device 65 is included in the second gripping portion. However, at least a portion of the base end surface 612 of the first storage device 61 may be included in the first gripping portion, and at least a portion of the base end surface 652 of the second storage device 65 may be included in the second gripping portion.

[0309] In the first embodiment described above, an example was given in which the first storage device 61 is held in a first position and the second storage device 65 is held in a second position by a single device holding section 70. However, the trolley may also be equipped with a dedicated first device holding section for holding the first storage device 61 in a first position and a dedicated second device holding section for holding the second storage device 65 in a second position.

[0310] In the first embodiment described above, an example was given in which the upper surface 611 of the first storage device 61 and the upper surface 651 of the second storage device 65 are at approximately the same height, and the base end surface 612 of the first storage device 61 and the base end surface 652 of the second storage device 65 are at approximately the same position in the delivery direction. However, it is also acceptable for the upper surface 611 of the first storage device 61 and the upper surface 651 of the second storage device 65 to be at approximately the same height. Alternatively, it is also acceptable for the base end surface 612 of the first storage device 61 and the base end surface 652 of the second storage device 65 to be at approximately the same position in the delivery direction.

[0311] In the first embodiment described above, a trolley 30 was given as an example of a parts supply device. However, the parts supply device may be a device that does not have a trolley function. In other words, the parts supply device may be a device in which a parts supply unit and a plurality of device holding parts are fixed on the floor.

[0312] In the first embodiment described above, a storage device 60 was given as an example of a supply device. However, the supply device can be any device that supplies carrier tape to a parts supply unit. For example, the end effector of an articulated robot can be used as an example of a supply device. In other words, the supply device does not need to have a storage section.

[0313] In the first embodiment described above, the holding portion is shown to be slidable in the feeding direction of the carrier tape 83, but the holding portion may also be swingable in the feeding direction or be expandable and contractible.
