Summary of Invention

Problems to be Solved by the Invention

[0004] In recent years, there has been a demand for more stable feeding of carrier tapes.

[0005] Accordingly, an object of the present invention is to provide a tape support device capable of feeding a carrier tape in a more stable manner.

Means for Solving the Problems

[0006] (1) A tape support device according to one aspect of the present invention comprises a tape support section for supporting a carrier tape, a detection section for detecting the carrier tape, a moving mechanism for moving the tape support section, and a control unit for controlling the tape support section and the moving mechanism, wherein the control unit controls the moving mechanism to move the tape support section along the direction of travel of the carrier tape, and causes the tape support section to support the carrier tape based on the detection of the carrier tape by the detection section.

[0007] According to the tape support device described in (1), the tape support unit supports the carrier tape based on the detection unit detecting the carrier tape, so the carrier tape can be reliably supported. This makes it possible to feed the carrier tape more stably.

[0008] (2) In the tape support device described in (1) above, the tape support portion may be provided with a pair of gripping members that sandwich the carrier tape in the width direction of the carrier tape.

[0009] (3) In the tape support device described in (2) above, the tape support portion may be provided with a restricting portion that restricts the movement of the carrier tape in the thickness direction of the carrier tape.

[0010] (4) In the tape support device described in (3) above, the control unit may, after gripping the carrier tape with the pair of gripping members, control the tape support unit to restrict the movement of the carrier tape in the thickness direction with the restricting unit.

[0011] According to the tape support device described in (4), the pair of gripping members grip the carrier tape, and then the restricting portion restricts the movement of the carrier tape in the thickness direction, thereby suppressing both the width direction and thickness direction displacement of the carrier tape. Therefore, the posture of the carrier tape can be stabilized, and stable feeding of the carrier tape becomes possible.

[0012] (5) In the tape support device described in (4) above, the tape support section may include a tape feeding section for feeding the carrier tape in the direction of travel, and the control section may control the tape support section so that the tape feeding section feeds the carrier tape in the direction of travel while the carrier tape is gripped by the pair of gripping members and the carrier tape is restricted by the restricting section.

[0013] According to the tape support device described in (5), the carrier tape is fed in the direction of travel by the tape feeding unit while the carrier tape is gripped by a pair of gripping members and restricted by a restricting unit. In other words, positional displacement in the width and thickness directions is suppressed when the carrier tape is fed, so more stable feeding of the carrier tape is possible.

[0014] (6) In the tape support device described in (5) above, the tape feeding unit may be a sprocket having a plurality of teeth that engage with the feeding holes of the carrier tape, and the carrier tape may be fed by the rotation of the sprocket.

[0015] According to the tape support device described in (6), when the carrier tape is fed by the rotation of the sprocket, the teeth of the sprocket engage with the feed holes of the carrier tape, so that displacement of the carrier tape can be further suppressed.

[0016] (7) In the tape support device described in (5) above, the tape feeding unit may be a roller that feeds the carrier tape by rotating in contact with the surface of the carrier tape.

[0017] According to the tape support device described in (7), even when the tape feeding section is a roller, positional displacement in the width direction and thickness direction is suppressed, so that stable feeding of the carrier tape is possible.

[0018] (8) In the tape support device according to any one of the above (5) to (7), the tape support portion may include a plurality of the tape feeding portions.

[0019] According to the tape support device described in (8), since the carrier tape is fed by the plurality of tape feeding portions, the carrier tape can be fed out more stably.

[0020] (9) In the tape support device according to the above (8), the plurality of the tape feeding portions may be arranged side by side in the width direction.

[0021] According to the tape support device described in (9), even when the plurality of tape feeding portions are arranged side by side in the width direction, positional deviation in the width direction and the thickness direction is suppressed, so that the carrier tape can be stably fed out.

[0022] (10) In the tape support device according to the above (8), the plurality of the tape feeding portions may be arranged side by side in the traveling direction.

[0023] According to the tape support device described in (10), even when the plurality of tape feeding portions are arranged side by side in the traveling direction, positional deviation in the width direction and the thickness direction is suppressed, so that the carrier tape can be stably fed out.

[0024] (11) In the tape support device according to any one of the above (5) to (10), the pair of gripping members may include a curved portion that curves along the traveling direction.

[0025] According to the tape support device described in (11), since the pair of gripping members are provided with the curved portion curved along the traveling direction, the carrier tape can be stably fed out even on a curved path.

[0026] (12) In the tape supporting apparatus according to any one of the above (1) to (11), the detection unit may detect a start point position of the carrier tape or feed holes formed in the carrier tape.

[0027] (13) In the tape supporting apparatus according to the above (2), the detection unit may output a detection signal to the control unit upon detecting the carrier tape, and the control unit may cause the tape supporting portion to support the carrier tape by narrowing an interval between the pair of gripping members based on the detection signal. Effects of the Invention

[0028] According to the present invention, the carrier tape can be fed out more stably. Brief Description of the Drawings

[0030] Hereinafter, embodiments of the present invention and modified versions thereof, including component mounting systems, will be described with reference to the drawings. Note that the embodiments and modified versions described below are either comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions of components, and connection configurations shown in the following embodiments and modified versions are examples only and are not intended to limit the present invention. Furthermore, each figure is a schematic diagram, and dimensions are not necessarily precisely represented. Additionally, 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 and tape cassette 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 the direction in which the component mounting device 20 and the tape cassette supply device 40 face each other.

[0031] 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.

[0032] (Embodiment 1) Figure 1 is an explanatory diagram showing the schematic configuration of the component mounting system 10 according to Embodiment 1. As shown in Figure 1, the component mounting system 10 according to Embodiment 1 comprises a component mounting device 20 and a tape cassette supply device 40.

[0033] 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 comprises a component mounting device body 20a and a trolley 30. The component mounting device body 20a includes a head 21 that takes components 87 (see Figure 5) from the component supply unit 31 on the trolley 30 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.

[0034] The trolley 30 is a trolley that is positioned by the positioning device 23 and connected to the main body of the parts mounting device 20a. The trolley 30 includes a parts supply unit 31 that pulls in a carrier tape 83 (see Figure 5) that stores parts 87 and supplies the parts 87, and a first tape cassette support section 70 (see Figure 2, etc.) that detachably holds a plurality of tape cassettes 60 that store the roll body 80 of the carrier tape 83.

[0035] The tape cassette supply device 40 is a device that supplies tape cassettes 60 to the first tape cassette support section 70 of the trolley 30 and retrieves empty tape cassettes 60 from the first tape cassette support section 70.

[0036] [Cart] Next, the details of the trolley 30 will be described. Figure 2 is a plan view showing the trolley 30 and the positioning device 23 according to Embodiment 1. 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 Embodiment 1. Figure 4 is an explanatory diagram showing the state in which the first tape cassette 61, which is an example of a tape cassette 60, and the second tape cassette 65, which is another example of a tape cassette 60, have been removed from the trolley 30 according to Embodiment 1. In Figure 4, the state in which the first guide 110 provided on the trolley 30 has also been removed.

[0037] As shown in Figures 2 to 4, the trolley 30 has a parts supply unit 31, a plurality of first tape cassette support sections 70, and a trolley body 32 that supports them. The parts supply unit 31 has a plurality of feeders 311 (parts supply devices) arranged in the X-axis direction so as to be paired with each first tape cassette support section 70. In Figure 3, the feeders at both ends in the X-axis direction Only the feeder 311 is shown. Each feeder 311 pulls out a carrier tape 83 from a tape cassette 60 (first tape cassette 61 or second tape cassette 65) held by each first tape cassette support section 70, and transports the components stored in the carrier tape 83 to the position where the head 21 will remove them.

[0038] 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.

[0039] On the base 300, a parts supply unit 31 is positioned in the positive Y-axis direction, and a plurality of first tape cassette support sections 70 are arranged in the X-axis direction in the negative Y-axis direction. For example, a pair of retaining wall sections 34 are erected on the base 300 in the positive Y-axis direction. A unit holding section 312 for holding the parts supply unit 31 is provided on the pair of retaining wall sections 34 so as to be able to move up and down. Positioning rollers 313 are provided at both ends of the unit holding section 312 in the X-axis direction for positioning each of the retaining wall sections 34 with respect to the positioning device 23.

[0040] On the base 300, a support base 35 is arranged in the negative Y-axis direction to support multiple first tape cassette support sections 70. At both ends of the support base 35 in the X-axis direction, a pair of support columns 351 and 352 are provided, which are 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 positive Y-axis 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 negative Y-axis 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.

[0041] Multiple first tape cassette support units 70, supported on the support base 35, are each designed to detachably hold either a first tape cassette 61 or a second tape cassette 65. The height position of the first tape cassette support units 70 can be adjusted according to the tape cassette 60 (first tape cassette 61 or second tape cassette 65) being supported.

[0042] Similarly, each first tape cassette support section 70 is configured to detachably hold either a first receiving device (not shown) or a second receiving device (not shown). The first receiving device is a device for receiving the roll body 80 provided in the first tape cassette 61, and the second receiving device is a device for receiving the roll body 80 provided in the second tape cassette 65.

[0043] For example, when a first tape cassette 61 is attached to a predetermined first tape cassette support section 70, a first receiving device is attached to the first tape cassette support section 70. In this case, the first tape cassette 61 is positioned in the negative Y-axis direction and the first receiving device is positioned in the positive Y-axis direction in the predetermined first tape cassette support section 70.

[0044] On the other hand, when a second tape cassette 65 is attached to a predetermined first tape cassette support section 70, a second receiving device is attached to the first tape cassette support section 70. In this case, the second tape cassette 65 is positioned in the negative Y-axis direction and the second receiving device is positioned in the positive Y-axis direction on the predetermined first tape cassette support section 70.

[0045] Furthermore, a height adjustment section (not shown) may be provided between the base 300 and the support base 35 to adjust the height position of the support base 35 relative to the base 300. In other words, the height adjustment section indirectly adjusts the height of the first tape cassette support section 70 by adjusting the height of the support base 35.

[0046] [Carrier Tape] Figure 5 is a perspective view showing the schematic configuration of the carrier tape 83 that constitutes the roll body 80 according to Embodiment 1. 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. Components 87 are stored in the component pockets 84. 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 of the feeder 311 engages. When this carrier tape 83 is wound, a roll body 80 (see Figure 6, etc.) is formed.

[0047] [Tape Cassette] Next, we will explain the details of the tape cassette 60. The first tape cassette 61 and the second tape cassette 65, which are examples of tape cassette 60, are different types of tape cassettes. Specifically, the first tape cassette 61, which is the first type, and the second tape cassette 65, which is the second type, differ in that they house roll bodies 80 of different diameters. For example, the first tape cassette 61 is designed to house a roll body 80 with a larger diameter than the second tape cassette 65. For this reason, the first tape cassette 61 itself is also larger than the second tape cassette 65. The size of the roll body 80 varies depending on the type of components that the carrier tape 83 houses.

[0048] Here, the first tape cassette 61 is used as an example to explain the tape cassette 60. The second tape cassette 65 has the same basic structure as the first tape cassette 61, except for the size of the storage compartment 62 which will be described later, so its explanation will be omitted.

[0049] Figure 6 is an exploded perspective view showing a part of the first tape cassette 61 according to Embodiment 1. As shown in Figure 6, the first tape cassette 61 comprises a storage section 62 and a feed section 93. The feed section 93 is the part that feeds the leading edge of the carrier tape 83 to the component supply unit 31.

[0050] The first tape cassette 61 has a flattened outer shape with the X-axis direction as the thickness direction, a feed unit 93 is arranged in the Z-axis positive direction, and a storage unit 62 is arranged in the Z-axis negative direction. The first tape cassette 61 is an example of a tape holding device that holds a carrier tape.

[0051] The storage unit 62 has a storage space H1 for storing the roll body 80. Specifically, the storage unit 62 has a frame body 621 and a pair of cover bodies 622, which together form the storage space H1.

[0052] The frame body 621 is a roughly U-shaped frame with the positive Y-axis direction open when viewed in the X-axis direction. The pair of cover bodies 622 are formed in a flat plate shape and are attached to the frame body 621 so as to sandwich it in the X-axis direction. As a result, each cover body 622 covers the recess of the frame body 621 in the X-axis direction. The recess of the frame body 621 and the pair of cover bodies 622 constitute the storage space H1. When an unused roll body 80 is stored in the storage space H1, the pair of cover bodies 622 completely cover the roll body 80. The storage space H1 is open in the positive Y-axis direction. That is, an opening 623 is provided at the end of the storage section 62 closest to the parts supply unit 31. This opening 623 allows the roll body 80 to move back and forth along the Y-axis direction relative to the storage space H1. A fall prevention part 624 is provided at the lower tip of the frame body 621 to prevent the roll body 80 from falling out of the opening 623.

[0053] The spacing between the pair of cover bodies 622, that is, the width (length in the X-axis direction) of the storage space H1, can be adjusted according to the width (length in the X-axis direction) of the roll body 80 housed in the storage space H1. For example, the spacing between the pair of cover bodies 622 may be adjusted by placing spacers (not shown) between each cover body 622 and the frame body 621 so as to avoid the storage space H1. Alternatively, the spacing between the pair of cover bodies 622 may be adjusted by swapping frame bodies 621 with different thicknesses (length in the X-axis direction).

[0054] Figure 7 is a plan view showing the shape of the lower end of the first tape cassette 61 according to Embodiment 1. Specifically, as shown in Figure 7, the lower end (the end in the negative Z-axis direction) of the frame body 621 of the first tape cassette 61 tapers towards the negative Z-axis direction. In addition, at the lower end of the frame body 621, the first end 625 in the positive Y-axis direction tapers towards the positive Y-axis direction. In other words, the first end 625 is formed in a tapered shape along the opposing direction.

[0055] Figure 8 is a plan view showing the shape of the end portion of the first tape cassette 61 in the negative Y-axis direction according to Embodiment 1. Specifically, as shown in Figures 6 and 8, the end portion of the first tape cassette 61 in the negative Y-axis direction is formed in steps. These are referred to as the first step portion 626 and the second step portion 627, respectively, starting from the positive Z-axis direction. The first step portion 626 protrudes more in the negative Y-axis direction than the second step portion 627. The ends of the first step portion 626 and the second step portion 627 in the negative Y-axis direction taper towards the negative Y-axis direction (see Figure 8).

[0056] As shown in Figure 6, a gripping portion 628 is provided at the upper end of the first tape cassette 61. The gripping portion 628 is the part that is gripped by the tape cassette supply device 40. In other words, when the first tape cassette 61 is supplied to the first tape cassette support 70 by the tape cassette supply device 40, or when it is removed from the first tape cassette support 70, the gripping portion 628 is gripped by the holding portion 43 (see Figure 17, etc.) of the tape cassette supply device 40. The gripping portion 628 is a rectangular notch that is long in the Y-axis direction and formed at the upper end of the first tape cassette 61. A pair of recesses 629 are formed in the gripping portion 628. Specifically, each recess 629 is formed on both end faces of the gripping portion 628 in the Y-axis direction. Each recess 629 has a recessed shape along the Y-axis direction.

[0057] Next, the feed unit 93 will be described. Figures 9 and 10 are exploded perspective views of the feed unit 93 according to Embodiment 1. Figures 9 and 10 are exploded perspective views taken from different directions. Figures 9 and 10 also show the carrier tape 83 that is fed by the feed unit 93. The direction of travel of the carrier tape 83 is inclined with respect to the Y-axis direction (corresponding to the Y1-axis direction, which will be described later: see Figure 17).

[0058] As shown in Figures 6, 9, and 10, the feed unit 93 is attached to a base unit 930 which is sandwiched and fixed between the gripped unit 628 and the frame body 621. Specifically, the base unit 930 is a long plate-shaped member in the Y-axis direction, and the feed unit 93 is fixed to its end in the Y-axis positive direction.

[0059] The feed unit 93 comprises a main body 94, a pair of holding members 95, a cam mechanism 96, and a locking member 97. The main body 94 is a block body fixed to the base 930, and a pair of holding members 95 are attached to both sides in the X-axis direction. The cam mechanism 96 is also built into the main body 94 so as to be able to move up and down. The upper end of the cam mechanism 96 protrudes from the upper surface of the main body 94. The cam mechanism 96 is able to reciprocate and slide in a direction inclined in the Z-axis direction (corresponding to the Z1 axis direction described later: see Figure 17). The cam mechanism 96 slides along the direction normal to the carrier tape 83 when it is being fed.

[0060] Furthermore, cam openings are provided on both sides of the main body 94 in the X-axis direction to expose a portion of the cam mechanism 96. A portion 941 is formed. On the side surface of the main body portion 94 in the negative X-axis direction, a receiving recess 942 for accommodating the locking member 97 is formed at the end in the positive Y-axis direction, and the locking member 97 is pivotably mounted within the receiving recess 942.

[0061] Each of the pair of retaining members 95 is made from a single sheet of metal. The retaining member 95 includes a fixing portion 951 and a deformable portion 952.

[0062] The fixing portion 951 is a part that is fixed to the side of the main body portion 94 and is formed in an inverted U shape in plan view. The deformation portion 952 comprises a first portion 953 extending downward from the middle portion of the fixing portion 951 in the Y-axis direction, a second portion 954 extending in the direction of travel from the lower end of the first portion 953, and a third portion 955 extending upward from the tip of the second portion 954.

[0063] Part 1 953 has a first opening 956 and a second opening 957 that extend along the sliding direction of the cam mechanism 96, and are aligned in the sliding direction. A partition 958 is provided between the first opening 956 and the second opening 957.

[0064] In the first part 953, a first support projection 959 is provided below the second opening 957, which is cut and bent toward the carrier tape 83. Thus, the first support projection 959 is positioned below the second opening 957. The first support projection 959 has a shape that extends along the direction of travel.

[0065] Part 2, section 954, connects Part 1, section 953, and Part 3, section 955, and extends along the direction of travel.

[0066] The third section 955 is provided with a second support projection 960 that is cut and bent toward the carrier tape 83. The second support projection 960 has a shape that extends along the direction of travel.

[0067] The cam mechanism 96 is a rod-shaped member oriented in the normal direction, and a drive source is connected to its upper end. The drive source is provided in the holding section 43, and when the holding section 43 holds the first tape cassette 61, the cam mechanism 96 is operated by the drive source.

[0068] In the cam mechanism 96, cam projections 961 are provided on both sides in the X-axis direction, protruding from the first opening 956 or the second opening 957 (see Figure 11A, etc.). The cam projections 961 are parts that expand and deform each retaining member 95.

[0069] The operation of the cam mechanism 96 and each retaining member 95 will be described below. Figures 11A to 11C are explanatory diagrams showing the operation of the cam mechanism 96 and each retaining member 95 according to Embodiment 1.

[0070] In the state shown in Figure 11A, the cam projection 961 of the cam mechanism 96 is positioned within the first opening 956 and does not push apart each of the holding members 95. In other words, each holding member 95 is not deformed, and the carrier tape 83 is supported by the first support projection 959 of each holding member 95. In this state, the second support projection 960 of each holding member 95 also supports the carrier tape 83. At this time, the pair of holding members 95 are in a supported state in which each support projection (two first support projections 959 and two second support projections 960) supports the carrier tape 83. In the supported state, the fixing part 951 is not deformed, and the front and rear ends of the fixing part 951 restrict the movement and rotation of the carrier tape 83 in the width direction. As a result, the carrier tape 83 is less likely to shift position. Therefore, external forces from the carrier tape 83 caused by positional shift are suppressed. In other words, deformation of the deformable part 952 due to the external force and the unexpected detachment of the carrier tape 83 are suppressed.

[0071] Subsequently, when the drive source operates and lowers the cam mechanism 96, as shown in Figure 11B, the cam projection 961 of the cam mechanism 96 contacts the partition portion 958 and pushes it open. The cam projection 961 is tapered outwards to smoothly push the partition portion 958 open, and its upper and lower surfaces are inclined. As the partition portion 958 is pushed open, the first portion 953 undergoes elastic deformation. As a result, the distance between the two first support projections 959 widens beyond the width of the carrier tape 83. Due to this deformation, the distance between the second portions 954 and the distance between the third portions 956 also widens, so the distance between the two second support projections 960 also widens beyond the width of the carrier tape 83. As a result, the carrier tape 83 falls off. At this time, the pair of retaining members 95 are wider in the width direction than when they were in the supporting state, and are in a released state that releases their support from the carrier tape 83.

[0072] Here, in the first part 953, the portion behind the first opening 956 in the direction of travel is designated as the rear portion 9531, and the portion in front of it is designated as the rear portion 9531. Furthermore, the cross-sectional area of ​​the rear portion 9531 along the direction of travel is designated as the first cross-sectional area, and the cross-sectional area of ​​the front portion 9532 along the direction of travel is designated as the second cross-sectional area. If the first cross-sectional area is larger than the second cross-sectional area, an imbalance occurs in the deformation of the first part 953, so the distance between the two second support protrusions 960 in the released state becomes larger than the distance between the two first support protrusions 959. This makes it possible to more reliably detach the carrier tape 83.

[0073] Subsequently, when the drive source operates and lowers the cam mechanism 96 further, the cam projection 961 of the cam mechanism 96 is positioned in the second opening 957, as shown in Figure 11C. This causes the first part 953 to elastically return to its original shape. In other words, the pair of retaining members 95 return to the supported state. Thus, while the cam mechanism 96 slides in one direction, the pair of retaining members 95 deform from the supported state to the released state, and then deform again to the supported state. The cam mechanism 96 may also rise after the released state so that the cam projection 961 is positioned in the first opening 956. In this case as well, the pair of retaining members 95 return to the supported state. Once returned to the supported state, the carrier tape 83 can be fed out again.

[0074] The cam mechanism 96 may also include an extrusion section 962 (the dashed-dot line in Figure 11B) that pushes out the carrier tape 83 when the pair of retaining members 95 deform into a released state. The extrusion section 962 is located at the lower end of the cam mechanism 96 and comes into contact with the upper surface of the carrier tape 83 as the cam mechanism 96 descends, pushing out the carrier tape 83. The extrusion section 962 pushes out the carrier tape 83, allowing the carrier tape 83 to fall out smoothly.

[0075] As shown in Figure 9, the locking member 97 is supported so as to swing along the direction of travel within the housing recess 942. The locking member 97 is a substantially L-shaped member in plan view, with its corner serving as the pivot point. The lower end of the locking member 97 enters the feed hole 88 of the carrier tape 83 and locks the feed hole 88. This suppresses misalignment of the carrier tape 83 in the width direction and the direction of travel. Furthermore, the lower end of the locking member 97 is restricted from swinging in the opposite direction to the direction of travel by the wall portion 943 of the housing recess 942. In other words, even if the carrier tape 83 tries to move backward, the locking member 97, which is locked to the feed hole 88, will not swing due to the wall portion 943. In this way, the locking member 97 suppresses the backward movement of the carrier tape 83. In addition, the locking member 97 has a stepped portion 971 located above its lower end that faces the upper surface of the carrier tape 83 when locked to the feed hole 88. This stepped portion 971 helps to suppress positional displacement (lifting) of the carrier tape 83 in the thickness direction.

[0076] Furthermore, a protruding biasing portion 972 is formed at the corner of the locking member 97. When the locking member 97 swings in accordance with the advance of the carrier tape 83 and its tip exits the feed hole 88, this biasing portion 972 contacts the wall portion 943 of the housing recess 942. This contact causes the biasing portion 972 to impart a biasing force to the locking member 97 in the opposite direction to the direction of advancement. As the locking member 97 returns to its original position, the lower end of the locking member 97 enters the other feed hole 88 and locks it in place. The biasing part 972 can take any form as long as it biases the locking member 97 in the opposite direction to the direction of travel. Other biasing parts 972 may be elastic members such as springs or rubber.

[0077] Furthermore, the form of the cam mechanism can be any as long as it is possible to switch between the supported state and the released state of the pair of retaining members. Figure 12 is an exploded perspective view of the feed section 93a according to a modified example. Figure 13 is a cross-sectional perspective view of the feed section 93a according to a modified example. In Figure 13, the plane along the direction of travel of the carrier tape 83 is the cut surface. In the following description, parts equivalent to those in the above-described configuration may be given the same reference numerals and their descriptions may be omitted.

[0078] As shown in Figures 12 and 13, the feed unit 93a comprises a main body 94a, a pair of holding members 95a, a cam mechanism 96a, and a locking member 97. The main body 94a is a block body fixed to the base 930, and a pair of holding members 95a are attached to both sides of it in the X-axis direction. The cam mechanism 96a is also built into the main body 94a so as to be slidable in the direction of travel.

[0079] Each of the pair of retaining members 95a is made from a single sheet of metal. Each retaining member 95a includes a fixing portion 951a and a deformable portion 952a.

[0080] The fixing portion 951a is a part that is fixed to the side surface of the main body portion 94a and is formed in a straight line. The deformable portion 952a comprises a first portion 953a provided in a U-shape in plan view from both ends of the fixing portion 951a, a second portion 954a extending in the direction of travel from the lower end of the first portion 953a, and a third portion 955a extending upward from the tip of the second portion 954a.

[0081] The first part 953a has an opening 956a, and a pair of cam projections 966a are formed on its lower edge, projecting toward the fixing part 951a. The pair of cam projections 966a are arranged along the direction of travel.

[0082] In part 953a, below the pair of cam projections 966a, a first support projection 959 is provided, which is cut and bent toward the carrier tape 83.

[0083] The cam mechanism 96a is a plate-shaped member oriented in the direction of travel, and a drive source is connected to one of its two ends. The cam mechanism 96a slides back and forth along the direction of travel by the power source. Specifically, the cam mechanism 96a has two elongated holes 961a that are aligned along the direction of travel. Each elongated hole 961a is connected to two cylindrical columnar parts 944a provided on the main body 94a. When power is transmitted to the cam mechanism 96a by the power source, each elongated hole 961a is guided by each columnar part 944a and slides along the direction of travel.

[0084] In the cam mechanism 96a, a plurality of cam recesses 967a are formed on both sides in the X-axis direction, each of which accommodates a cam projection 966a. When each cam projection 966a is accommodated in each cam recess 967a, the pair of retaining members 95a are in a supported state.

[0085] On the other hand, when the cam mechanism 96a slides and each cam recess 967a attempts to detach from each cam projection 966a, each cam recess 967a pushes open each cam projection 966a. As a result, the pair of retaining members 95a are released.

[0086] Figure 14 is a front view of the feeding section 93b according to another modified example. As shown in Figure 14, each holding member 95b has a float suppression projection 963b positioned above the second support projection 960. Specifically, each float suppression projection 963b is a projection cut and bent toward the carrier tape 83. Each float suppression projection 963b, together with each second support projection 960, is positioned to sandwich the carrier tape 83 in the thickness direction. Each float suppression projection 963b can suppress the float (positional displacement in the normal direction) of the carrier tape 83.

[0087] [Guide Section] As shown in Figures 3 and 4, the first guide 110 is an example of a guide that guides the tape cassette 60 being transferred by the holding part 43 of the tape cassette supply device 40. In the following description, the first tape cassette 61 is used as an example of the tape cassette 60, but the same applies to the second tape cassette 65.

[0088] The first guide 110 is arranged along the Y-axis direction (the direction in which the component mounting device 20 and the tape cassette supply device 40 are facing each other). Multiple first guides 110 are provided so as to sandwich the first tape cassette 61, which is supported by the trolley 30, in the X-axis direction. The first guides 110 are detachably attached to the trolley 30. Therefore, it is possible to attach each first guide 110 to an appropriate position according to the thickness (length in the X-axis direction) of the first tape cassette 61. In particular, in this embodiment, a handle 111 is formed on the upper part of the first guide 110, so that the operator can easily attach and detach the first guide 110. From the viewpoint of workability, it is preferable that the handle 111 is positioned away from both the first tape cassette 61 supported by the first tape cassette support part 70 and the feeder 311.

[0089] The first guide 110 is a plate-shaped member that is parallel to the YZ plane and elongated in the Y-axis direction. When the first guide 110 is attached to the component mounting device 20, it is sized to cover at least the area from the end of the component mounting device 20 in the negative Y-axis direction to the middle part in the Y-axis direction. In this embodiment, when the first guide 110 is attached to the component mounting device 20, it is sized to cover an area from the end of the component mounting device 20 in the negative Y-axis direction to the middle part or more in the Y-axis direction. Furthermore, the first guide 110 is sized to cover more than half of the area of ​​the first tape cassette 61 and the second tape cassette 65 supported by the first tape cassette support part 70 in an X-axis view. Because the first guide 110 is sized in this way, it is possible to stably guide the first tape cassette 61 that is transferred by the holding part 43.

[0090] [Tape cassette feeder] Next, the tape cassette supply device 40 will be described. Figure 15 is a perspective view showing the schematic configuration of the tape cassette supply device 40 according to Embodiment 1. As shown in Figure 15, the tape cassette supply device 40 is a movable device that is transported on the floor surface by a transport vehicle 490, for example, an AGV (Automatic Guided Vehicle), and is a device that supplies and collects the first tape cassette 61 to the component mounting device 20. In other words, the tape cassette supply device 40 is a device that moves between multiple component mounting devices 20 by the transport vehicle 490 and transfers the first tape cassette 61 to each component mounting device 20.

[0091] The tape cassette feeder 40 has an open end in the positive Y-axis direction, and a pair of connecting guide portions 41 protruding in the positive Y-axis direction are provided at this end. These connecting guide portions 41 are members that guide the movement of the tape cassette feeder 40 when it is connected to the positioning device 23. Specifically, the connecting guide portions 41 have rollers, and these rollers roll along the wall surface of the positioning device 23 to guide the movement of the tape cassette feeder 40 during connection.

[0092] Inside the tape cassette supply device 40 are a support section 42 that supports the first tape cassette 61 and a holding section 43 (see Figure 17, etc.) that holds the first tape cassette 61 supported by the support section 42.

[0093] The support unit 42 has a plurality of second tape cassette support units 421 that individually support each first tape cassette 61, and a mounting base 422 on which the plurality of second tape cassette support units 421 are placed. Each second tape cassette support unit 421 is a slot extending in the Y-axis direction and is arranged along the X-axis direction with respect to the mounting base 422. In the connected state, each second tape cassette support unit 421 faces each first tape cassette support unit 70 of the trolley 30 in the Y-axis direction.

[0094] The support portion 42 is moved in the X-axis direction by a support portion moving mechanism (not shown). This aligns the second tape cassette support portion 421 with the first tape cassette support portion 70.

[0095] The mounting base 422 is a box-shaped body with openings in the Z-axis positive direction and the Y-axis positive direction, and a plurality of second tape cassette support units 421 are mounted on its bottom. In the mounting base 422, each of a pair of opposing walls in the X-axis direction is a second guide 423. Each second guide 423 is arranged along the Y-axis direction (the direction in which the component mounting device 20 and the tape cassette supply device 40 face each other). Each second guide 423 guides the first tape cassette 61 housed between them when it is transferred to the component mounting device 20 by the holding unit 43. In the case of a first tape cassette 61 having a thickness corresponding to the distance between the pair of second guides 423, only one first tape cassette 61 is housed between the pair of second guides 423. In the case of a thin first tape cassette 61, multiple first tape cassettes 61 are housed between the pair of second guides 423. The distance between the pair of second guides 423 may be set so that only one thin first tape cassette 61 is housed. In this case, multiple mounting bases 422 may be provided on the support portion 42.

[0096] In this embodiment, an example is shown in which the mounting base 422, which is made up of a box, is equipped with a pair of second guides 423. However, the second guides may be detachable from the tape cassette supply device 40. In this case, it is also possible to place the detachable second guides between the pair of second guides 423. If the second guides are detachable, it is possible to attach each second guide to an appropriate position according to the thickness (length in the X-axis direction) of the first tape cassette 61.

[0097] Figure 16 is a schematic diagram showing the state when the first tape cassette 61 according to the embodiment is transferred between the tape cassette supply device 40 and the component mounting device 20. In Figure 16, the first tape cassette 61, a pair of first guides 110, and a pair of second guides 423 are shown from the Z-axis positive direction. Figure 16 illustrates the case in which one first tape cassette 61 is placed between the pair of first guides 110 and one first tape cassette 61 is placed between the pair of second guides 423.

[0098] It is desirable that the tape cassette supply device 40 and the component mounting device 20 be arranged along the Y-axis. However, due to individual differences in each device, vibrations during the movement of the tape cassette supply device 40, and vibrations caused by the operation of each drive unit, the tape cassette supply device 40 and the component mounting device 20 may become misaligned. Figure 16 illustrates this misalignment in an exaggerated manner. Even if such misalignment occurs, the first tape cassette 61 is stably guided by the first guide 110 and the second guide 423.

[0099] For example, as shown in Figure 16, suppose that a pair of second guides 423 are arranged along the Y-axis, while a pair of first guides 110 are inclined with respect to the Y-axis. In this state, the holding unit 43 transfers the first tape cassette 61 from the component mounting device 20 to the tape cassette supply device 40. During the transfer, the first tape cassette 61 is guided along the Y-axis by the pair of second guides 423, and its first end 625 enters the pair of first guides 110. At this time, because the first end 625 has a tapered shape, it enters the pair of first guides 110 smoothly. After entering, the first tape cassette 61 moves to a predetermined position while being guided by the pair of first guides 110.

[0100] On the other hand, when the holding unit 43 retrieves the first tape cassette 61 from the tape cassette supply device 40 to the component mounting device 20, the first tape cassette 61 is guided by a pair of first guides 110, and the first stage portion 626 and the second stage portion 627 (not shown in Figure 16) enter the pair of second guides 423. At this time, because the first stage portion 626 and the second stage portion 627 have a tapered shape, they enter the pair of second guides 423 smoothly. After entering, the first tape cassette 61 moves to a predetermined position while being guided by the pair of second guides 423.

[0101] [Holding part] As shown in Figure 15, the holding unit 43 is positioned above the support unit 42. The holding unit 43 is moved by a moving mechanism 45 provided in the tape cassette supply device 40. The moving mechanism 45 moves the holding unit 43 in the X-axis, Y-axis, and Z-axis directions, and also rotates the holding unit 43 around the Z-axis direction. In cooperation with the moving mechanism 45, the holding unit 43 holds the first tape cassettes 61 supported by each second tape cassette support unit 421 and supplies them to the component mounting device 20. Also, in cooperation with the moving mechanism 45, the holding unit 43 holds the first tape cassettes 61 supported by each first tape cassette support unit 70 of the component mounting device 20, moves them to the tape cassette supply device 40, and retrieves them.

[0102] Figure 17 is an explanatory diagram showing the schematic configuration of the holding unit 43 according to Embodiment 1. As shown in Figure 17, the holding unit 43 comprises a cassette gripping unit 400, a tape support unit 500, and a control unit 600 that controls them. The cassette gripping unit 400 and the tape support unit 500 are integrally configured side by side in the Y-axis direction. Specifically, the cassette gripping unit 400 is positioned in the Y-axis positive direction of the tape support unit 500. The control unit 600 has a CPU, RAM, and ROM, and the CPU loads a program in ROM into RAM and executes it to control the cassette gripping unit 400, the tape support unit 500, the moving mechanism 45, and the drive source of the cam mechanism 96.

[0103] [Cassette gripping section] The cassette gripping section 400 is the part that grips the first tape cassette 61. Specifically, the cassette gripping section 400 comprises a gripping body section 410 and a pair of opening / closing members 420. The gripping body section 410 is connected to the moving mechanism 45 and supports the pair of opening / closing members 420. The gripping body section 410 is equipped with a cassette sensor (not shown) for detecting the first tape cassette 61 and an opening / closing drive unit (not shown) for rotating and sliding the pair of opening / closing members 420. The control unit 600 controls the moving mechanism 45 and the opening / closing drive unit based on the detection result of the cassette sensor.

[0104] A pair of opening / closing members 420 are rotatably and slidably supported by a gripping body 410, and grip the gripped portion 628 of the first tape cassette 61 by rotating and sliding. The pair of opening / closing members 420 are arranged side by side in the Y-axis direction, and one end of each is rotatably supported by the gripping body 410. The other end of the pair of opening / closing members 420 is provided with a pair of pin members 424 that engage with a recess 629 (see Figure 24, etc.) of the gripped portion 628. As shown in Figure 17, the state in which each opening / closing member 420 has its pin members 424 facing upward is the standby position. When each opening / closing member 420 rotates from the standby position and its pin members 424 face in the Y-axis direction, it is the gripping position.

[0105] The pair of opening / closing members 420 are slidable in the Y-axis direction by guide rails 411 provided on the gripping body 410. When each opening / closing member 420 is in a gripping position, it is movable toward each other in the direction of separation and toward each other by the guide rails 411. When each opening / closing member 420 moves toward each other in the direction of separation in the gripping position, each pin member 424 engages with each recess 629 of the gripped portion 628, and grips the gripped portion 628 (see Figure 24).

[0106] [Tape support section] The tape support section 500 is the part that supports the carrier tape 83. The tape support section 500 comprises a support connecting section 510 and a support section 520. The support connecting section 510 is connected to the gripping body section 410 and supports the support section 520. The support connecting section 510 is equipped with an operating drive source (not shown) for operating each operating part of the support section 520. The operating drive source is controlled by the control unit 600. There may be one or more operating drive sources, as long as they can operate each operating part of the support section 520.

[0107] The support portion 520 is the part that supports the carrier tape 83 while it is being fed out. Figure 18 is a perspective view showing the support portion 520 according to Embodiment 1. Figure 19 is a schematic cross-sectional view showing the support portion 520 according to Embodiment 1. In Figures 18 and 19, the Y1 axis direction is the direction of travel of the carrier tape 83 inclined with respect to the Y axis direction. More precisely, the positive Y1 axis direction is the direction of travel, and the negative Y1 axis direction is the rear of the direction of travel. The Z1 axis direction is the normal direction of the carrier tape 83 inclined with respect to the Z axis direction (see Figure 17). The direction of travel and the normal direction are based on the state in which the carrier tape 83 is supported by the support portion 520.

[0108] As shown in Figures 18 and 19, the support unit 520 includes a pair of gripping members 530, a regulating unit 540, a tape feeding unit 550, and a detection unit 560.

[0109] The pair of gripping members 530 are members that grip the carrier tape 83 in the width direction (X-axis direction) of the carrier tape 83. The pair of gripping members 530 are arranged side by side in the X-axis direction, with one gripping member 530 in the negative X-axis direction being fixed, and the other gripping member 530 in the positive X-axis direction being movable in the X-axis direction. The other gripping member 530 moves in the X-axis direction by a drive source (not shown). This causes the distance between the pair of gripping members 530 to vary. Each gripping member 530 is made of sheet metal, and its lower end is a flat plate portion 531 that is bent inward. The flat plate portion 531 is a flat plate along the Y1 axis direction (see Figure 17). Each flat plate portion 531 supports the carrier tape 83 from below.

[0110] The restricting portion 540 is a part that restricts the movement of the carrier tape 83 in the thickness direction (normal direction: Z1 axis direction). The restricting portion 540 is located between a pair of gripping members 530. The restricting portion 540 has a pair of restricting members 541 arranged side by side in the X axis direction. Each restricting member 541 is made of sheet metal and has a flat plate portion 542 at its lower end that is bent inward. The flat plate portion 542 is a flat plate along the Y1 axis direction.

[0111] The pair of restricting members 541 are capable of moving up and down along the Z1 axis. The pair of restricting members 541 are moved up and down by a drive source (not shown). When lowered, the flat plate portion 542 of each restricting member 541 approaches the carrier tape 83 supported by the flat plate portion 531 of the pair of gripping members 530. This restricts the movement (floating) of the carrier tape 83 in the positive Z1 axis direction.

[0112] Furthermore, of the pair of regulating members 541, one regulating member 541 in the negative X-axis direction is attached to a support column 545 that supports the tape feed unit 550 via an elastic member 543 (e.g., a spring or rubber). The support column 545 moves up and down together with the regulating member 541. The support column 545 also moves downward against the biasing force of the elastic member 543 due to a force from an operating drive source (not shown). When the force from the operating drive source is released, the support column 545 moves upward due to the biasing force of the elastic member 543.

[0113] Of the pair of restricting members 541, the other restricting member 541 in the positive X-axis direction is movable in the X-axis direction in conjunction with the other gripping member 530.

[0114] The tape feed unit 550 is the part that feeds the carrier tape 83 in the direction of travel. Specifically, the tape feed unit 550 is a sprocket having a plurality of teeth 551 that engage with the feed holes 88 of the carrier tape 83. The tape feed unit 550 is rotatably supported with respect to the support column 545. A disc 555 is provided coaxially with the tape feed unit 550, and a belt 552 is attached to this disc 555. When the belt 552 is rotated by an operating drive source (not shown), the tape feed unit 550 rotates together with the disc 555, and the carrier tape 83, which is engaged with the teeth 551, is fed in the direction of travel.

[0115] The detection unit 560 is positioned in the positive Y1 axis direction relative to the support unit 520 and is an optical sensor that detects the carrier tape 83. Specifically, when the detection unit 560 detects the feed holes 88 of the carrier tape 83, it outputs a detection signal to the control unit 600. Based on the detection signal, the control unit 600 controls the drive source and operates each of the operating parts of the support unit 520 (a pair of gripping members 530, a regulating unit 540, and a tape feed unit 550). The detection unit 560 can also detect the starting position of the carrier tape 83.

[0116] [Tape feeding method] Next, the tape feeding method using the support part 520 will be described. Figures 20 to 22 are explanatory diagrams showing each step of the tape feeding method according to Embodiment 1.

[0117] As shown in Figure 20, in the state before supporting the carrier tape 83, the pair of gripping members 530 are spread apart to the point where they cannot support the carrier tape 83. The pair of regulating members 541 are also positioned at an interval corresponding to the interval of the pair of gripping members 530 and are in an elevated position.

[0118] When it is time to support the carrier tape 83, the control unit 600 controls the drive source to narrow the distance between the pair of gripping members 530 and the pair of restricting members 541. As a result, as shown in Figure 19, the carrier tape 83 is gripped in the width direction (X-axis direction) by the pair of gripping members 530. In other words, the X-axis positional displacement of the carrier tape 83 is restricted. The carrier tape 83 is supported from below by the flat plate portion 531 of each gripping member 530.

[0119] Next, the control unit 600 controls the drive source to lower the pair of restricting members 541, as shown in Figure 21. This causes the flat plate portions 542 of the pair of restricting members 541 to approach the carrier tape 83 supported by the pair of gripping members 530. This restricts the movement (floating) of the carrier tape 83 in the positive Z1 axis direction. At this time, each flat plate portion 542 is positioned with a small gap from the upper surface of the carrier tape 83, so that each flat plate portion 542 does not easily obstruct the feeding of the carrier tape 83. At this time, the control unit 600 may control the movement mechanism 45 to move the tape support portion 500 along the Y1 axis direction while receiving a detection signal from the detection unit 560. This allows the control unit 600 to recognize the position of the feed holes 88 of the carrier tape 83 and position the teeth 551 of the tape feeding unit 550 at the position corresponding to the recognized feed holes 88.

[0120] Next, as shown in Figure 22, the control unit 600 controls the drive source to lower the support column 545 to resist the biasing force of the elastic member 543, thereby engaging the teeth 551 of the tape feeding unit 550 with the feed holes 88 of the carrier tape 83.

[0121] Next, the control unit 600 controls the drive source to rotate the belt 552. This causes the disc 555 and the tape feeding unit 550 to rotate, and the carrier tape 83, which is engaged with the teeth 551, is fed in the direction of travel. In this way, with the carrier tape 83 being gripped by the pair of gripping members 530 and restricted by the restricting unit 540, the tape feeding unit 550 feeds the carrier tape 83 in the direction of travel.

[0122] In this tape feeding method, the carrier tape 83 is first gripped by a pair of gripping members 530, and then the carrier tape 83 is fed forward in the direction of travel while the movement of the carrier tape 83 in the thickness direction is restricted by the restricting section 540.

[0123] [Method for gripping tape cassettes] Next, the method for gripping the tape cassette performed by the holding unit 43 will be described. Figures 23 to 26 are explanatory diagrams showing each step of the tape cassette gripping method according to Embodiment 1.

[0124] This section describes the process from supplying the first tape cassette 61 from the tape cassette supply device 40 to the trolley 30, to then feeding the carrier tape 83 from the first tape cassette 61 to the feeder 311.

[0125] As shown in Figure 23, in the state before gripping the first tape cassette 61 in the tape cassette supply device 40, the cassette gripping section 400 is in a standby position with a pair of opening / closing members 420 that are closest to each other in the Y-axis direction.

[0126] The control unit 600 controls the moving mechanism 45 while monitoring the detection results of the cassette sensor to move the holding unit 43 so that the pair of opening / closing members 420 are positioned above the gripping portion 628 of the first tape cassette 61.

[0127] Next, the control unit 600 controls the moving mechanism 45 as shown in Figure 24 to lower the holding unit 43 so that the pair of opening / closing members 420 are positioned within the gripped portion 628. After that, the control unit 600 controls the opening / closing drive unit to slide the pair of opening / closing members 420 in the separation direction. When each opening / closing member 420 moves in the separation direction in a gripping position, each pin member 424 engages with each recess 629 of the gripped portion 628, gripping the gripped portion 628 (see Figure 24). The position of the cassette gripping unit 400 at this point is the gripping position. The gripping position is the position in which the cassette gripping unit 400 grips the first tape cassette 61. In the gripping position, the tape support unit 500 is separated from the carrier tape 83 held by the feed unit 93 of the first tape cassette 61.

[0128] After gripping, the control unit 600 controls the moving mechanism 45 to transfer the first tape cassette 61 to the trolley 30. During transfer, as described above, the first tape cassette 61 is guided in the Y-axis direction by the pair of second guides 423, and its first end 625 enters the pair of first guides 110. After entering, the first tape cassette 61 is guided by the pair of first guides 110 to a predetermined position on the trolley 30 (see Figure 16).

[0129] Here, the cassette gripping section 400 only grips the gripped portion 628 of the first tape cassette 61 with a pair of opening / closing members 420, so the first tape cassette 61 is not secure during transfer. It can assume a fixed position. However, since the first tape cassette 61 is guided by each first guide 110 and each second guide 423, the position of the first tape cassette 61 is stabilized. Therefore, it is possible to make the transfer of the first tape cassette 61 more stable.

[0130] In particular, when gripping, the first tape cassette 61 tends to swing around the pair of pin members 424, but the posture of the first tape cassette 61 is stabilized by the first guide 110 and the second guide 423. In other words, the first tape cassette 61 itself does not need to have a structure that can withstand swinging, so the structure of the first tape cassette 61 can be simplified.

[0131] Next, as shown in Figure 25, the control unit 600 controls the opening / closing drive unit to slide the pair of opening / closing members 420 toward each other, releasing their grip on the gripped portion 628, and then sets each opening / closing member 420 to a standby position. After that, the control unit 600 controls the moving mechanism 45 to lower the holding portion 43 so that the tape support portion 500 is positioned to support the carrier tape 83. At this point, the cassette gripping portion 400 is in the retracted position. The retracted position is the position where the cassette gripping portion 400 is retracted from the first tape cassette 61. In this way, the cassette gripping portion 400 moves between the gripping position and the retracted position.

[0132] Next, the control unit 600 controls the drive source for the tape support unit 500 to grip the carrier tape 83 with the support unit 520. Once gripping is complete, the control unit 600 controls the drive source for the cam mechanism 96 to lower the cam mechanism 96 and release the pair of retaining members 95. As a result, the carrier tape 83 falls off the pair of retaining members 95 (see Figures 11A to 11C). After the fall, the control unit 600 controls the drive source for the cam mechanism 96 to raise the cam mechanism 96 and return the pair of retaining members 95 to the supported state.

[0133] Subsequently, the control unit 600 controls the movement mechanism 45 to move the holding unit 43 so that the leading edge of the carrier tape 83 is positioned near the feeder 311 (see Figure 26). In this way, the tape support unit 500 moves while supporting the carrier tape 83, thereby pulling the carrier tape 83 out of the first tape cassette 61. This pulls the carrier tape 83 out of the first tape cassette 61 to the feeder 311. Alternatively, the carrier tape 83 may be pulled out while being supported by the pair of holding members 95.

[0134] [effect] As explained above, after the pair of gripping members 530 grip the carrier tape 83, the restricting portion 540 restricts the movement of the carrier tape 83 in the thickness direction, thereby suppressing positional displacement of the carrier tape 83 in both the width direction and the thickness direction. Therefore, the posture of the carrier tape 83 can be stabilized, and stable feeding of the carrier tape 83 becomes possible.

[0135] With the carrier tape 83 gripped by a pair of gripping members 530 and restricted by the restricting section 540, the carrier tape 83 is fed in the direction of travel by the tape feeding section 550. In other words, positional displacement in the width and thickness directions is suppressed when the carrier tape 83 is fed, so more stable feeding of the carrier tape 83 is possible.

[0136] When the carrier tape 83 is fed by the rotation of the sprocket, which is the tape feed unit 550, the teeth 551 of the sprocket engage with the feed holes 88 of the carrier tape 83, thereby further suppressing misalignment of the carrier tape 83.

[0137] When the tape support unit 500 moves in the Y1 axis direction, the detection unit 560 detects the carrier tape 83, and based on this, the tape support unit 500 supports the carrier tape 83, thus ensuring reliable support of the carrier tape 83.

[0138] Since the pair of retaining members 95 are configured to be deformable between a supported state and a released state, the carrier tape 83 can be supported in the supported state, and the support for the carrier tape 83 can be released in the released state. In this way, the structure for releasing the support for the carrier tape 83 can be simplified.

[0139] The cam mechanism 96 engages with the pair of retaining members 95, causing the pair of retaining members 95 to deform between a supported state and a released state, thus allowing the pair of retaining members 95 to deform smoothly.

[0140] Since the first cross-sectional area of ​​the portion of the holding member 95 located behind the openings (first opening 956 and second opening 957) (rear portion 9531) is larger than the second cross-sectional area of ​​the portion located in front of the openings (front portion 9532), the amount of deformation of the portion in front of the openings can be made larger than the amount of deformation of the rear portion. This prevents the second support projection 960 from interfering with the carrier tape 83 when the release state is achieved.

[0141] The sliding motion of the cam mechanism 96a in the direction of travel allows for a smooth switching between the supported state and the released state of the pair of retaining members 95a.

[0142] The sliding motion of the cam mechanism 96 in the normal direction allows for a smooth switching between the supported state and the released state of the pair of retaining members 95.

[0143] As the cam mechanism 96 slides in one direction, the pair of retaining members 95 deform from a supported state to a released state, and then deform back to a supported state. Therefore, switching from the supported state to the released state and from the released state to the supported state can be performed with a one-way sliding motion.

[0144] As the pair of retaining members 95 deform to a released state, the extrusion unit 962 pushes out the carrier tape 83, allowing the carrier tape 83 to be smoothly detached from the pair of retaining members 95.

[0145] The locking member 97 can suppress misalignment of the carrier tape 83 in the direction of travel. Since the locking member 97 is biased in the opposite direction to the direction of travel by the biasing part 972, when the carrier tape 83 is stopped, misalignment in the opposite direction to the direction of travel can be suppressed. When the carrier tape 83 moves, the locking member 97 swings against the biasing of the biasing part 972 and disengages from the feed hole 88, so it does not easily obstruct the movement of the carrier tape 83. In other words, it is possible to allow the movement of the carrier tape 83 while suppressing misalignment of the carrier tape 83 in the direction of travel and in the opposite direction.

[0146] Since the stepped portion 971 of the locking member 97 faces the upper surface of the carrier tape 83, positional displacement of the carrier tape 83 in the thickness direction can be suppressed.

[0147] Since the pair of retaining members 95 restrict the movement of the carrier tape 83 in the width direction at positions different from the support protrusions (first support protrusion 959 and second support protrusion 960), misalignment of the carrier tape in the width direction can be suppressed.

[0148] Since the lifting suppression projection 963b is positioned to sandwich the carrier tape 83 in the thickness direction together with the second support projection 960, the lifting suppression projection 963b can suppress the lifting of the carrier tape 83.

[0149] When the tape support section 500 supports the carrier tape 83, the control unit 600 moves the cassette gripping section 400 to a retracted position, thereby preventing the cassette gripping section 400 from unnecessarily interfering with the first tape cassette 61.

[0150] The cassette gripping section 400, which has a pair of rotatable opening and closing members 420, can also be moved to a retracted position, thereby preventing the cassette gripping section 400 from unnecessarily interfering with the first tape cassette 61.

[0151] Even in a structure where a pair of opening / closing members 420 of the cassette gripping portion 400 grip the gripped portion 628 of the first tape cassette 61, it is possible to suppress unnecessary interference between the cassette gripping portion 400 and the first tape cassette 61.

[0152] The engagement between the pair of pin members 424 and the pair of recesses 629 prevents the cassette gripping portion 400 from unnecessarily interfering with the first tape cassette 61, even in a structure where the pair of opening / closing members 420 grip the gripped portion 628 of the first tape cassette 61.

[0153] When the first tape cassette 61 is supplied to the component mounting device 20, the orientation of the first tape cassette 61 is stable. This makes it possible to more accurately support the carrier tape 83 with the tape support section 500. Furthermore, when the first tape cassette 61 is transferred to the component mounting device 20, the tape support section 500 does not support the carrier tape 83, so vibrations from the first tape cassette 61 are less likely to be transmitted to the carrier tape 83. This helps to suppress damage to the carrier tape 83.

[0154] As the tape support unit 500 moves while supporting the carrier tape 83, the carrier tape 83 is pulled out from the first tape cassette 61, allowing the carrier tape 83 to be pulled out more stably.

[0155] The first guide 110 and the second guide 423 (guide section), which are arranged along the Y-axis direction (opposite direction), guide the first tape cassette 61 (tape cassette) that is transferred by the holding section 43, so that the first tape cassette 61 can be smoothly transferred from the tape cassette supply device 40 to the component mounting device 20.

[0156] Since the first guide 110 and the second guide 423 are detachably provided on at least one of the component mounting device 20 and the tape cassette supply device 40, the first guide 110 and the second guide 423 can be removed when they are not needed. Furthermore, it is possible to install the first guide 110 and the second guide 423 in appropriate positions according to the width of the first tape cassette 61. These features enhance the convenience of the first guide 110 and the second guide 423.

[0157] Since the plate-shaped members provided along the Y-axis are the first guide 110 and the second guide 423, the contact area between the first guide 110 and the second guide 423 and the first tape cassette 61 during guiding can be increased. Therefore, the first tape cassette 61 can be transferred more stably.

[0158] Since multiple first guides 110 and second guides 423 are provided to sandwich the first tape cassette 61, it is possible to stably transfer one first tape cassette 61.

[0159] Since the first guide 110 is provided on the component mounting device 20, the movement of the first tape cassette 61 on the component mounting device 20 side is guided by the first guide 110. On the other hand, since the second guide 423 is provided on the tape cassette supply device 40, the movement of the tape cassette supply device 40 side The movement of the first tape cassette 61 is guided by the second guide 423. Since each movement is stabilized in this way, it is possible to make the transfer of the first tape cassette 61 more stable.

[0160] A pair of opening and closing members 420 of the cassette gripping portion 400 provided on the holding portion 43 hold the first tape cassette 61 by gripping the gripped portion 628 of the first tape cassette 61. In this state, the first tape cassette 61 may be in an unstable position when transferred, but the position of the first tape cassette 61 is stabilized because it is guided by the first guide 110 and the second guide 423. Therefore, it is possible to make the transfer of the first tape cassette 61 more stable.

[0161] The first tape cassette 61 is held in place by a pair of pin members 424 provided on a pair of opening / closing members 420 engaging with a pair of recesses 629 provided on a gripping portion 628. In this case, the first tape cassette 61 is prone to swinging around the pair of pin members 424, but the posture of the first tape cassette 61 is stabilized by the first guide 110 and the second guide 423. In other words, the first tape cassette 61 does not need to have a structure that can withstand swinging, so the structure of the first tape cassette 61 can be simplified.

[0162] Since the first end 625 of the first tape cassette 61 is tapered along the Y-axis, the first end 625 is less likely to get caught on the guide, allowing the first tape cassette 61 to be guided smoothly.

[0163] (Embodiment 2) Next, Embodiment 2 of the present disclosure will be described. In the following description, parts equivalent to those in Embodiment 1 may be denoted by the same reference numerals and their descriptions may be omitted.

[0164] Figure 27 is a plan view showing the schematic configuration of the support portion 520b according to Embodiment 2. As shown in Figure 27, the pair of gripping members 530b of the support portion 520b have a curved portion 532b at their lower end that curves along the direction of travel. The curved portion 532b is a convex curved surface that is convex in the Z1 axis plus direction. The curved portion 532b of each gripping member 530b supports the carrier tape 83 from below.

[0165] Thus, since the pair of gripping members 530b are equipped with curved portions 532b that curve along the direction of travel, the carrier tape 83 can be fed out stably even along a curved path. In particular, the bent portions of the carrier tape 84 that occur between the component pockets 84 can easily pass over the ends of the pair of gripping members 530b, enabling stable feeding.

[0166] (Embodiment 3) Next, Embodiment 3 of the present disclosure will be described. Figure 28 is a schematic cross-sectional view showing the support portion 520c according to Embodiment 3. As shown in Figure 28, the tape feeding portion 550c provided on the support portion 520c is a roller that feeds the carrier tape 83 by rotating in contact with the surface (upper surface) of the carrier tape 83.

[0167] Thus, even when the tape feeding section 550c is a roller, positional misalignment in the width and thickness directions is suppressed, enabling stable feeding of the carrier tape 83.

[0168] (Embodiment 4) Next, Embodiment 4 of the present disclosure will be described. Figure 29 is a schematic cross-sectional view showing the support portion 520d according to Embodiment 4. As shown in Figure 29, the support portion 520d is provided with a plurality of tape feeding portions 550d. Each tape feeding portion 550d is arranged in the width direction of the carrier tape 83d. Each tape feeding portion 550d is a sprocket. For this reason, the carrier tape 83d is provided with two rows of feeding holes 88d into which the teeth 551d of the sprocket of each tape feeding portion 550d engage.

[0169] In this way, the carrier tape 83d is fed by multiple tape feed units 550d, making it possible to feed the carrier tape 83d more stably.

[0170] In particular, even when multiple tape feed units 550d are arranged side by side in the width direction, positional misalignment in both the width and thickness directions is suppressed, enabling stable feeding of the carrier tape 83d. Furthermore, the driving force can be averaged in the width direction of the carrier tape 83d. In addition, since the teeth 551d of each tape feed unit 550d engage with the feed holes 88d of each row of the carrier tape 83, positional misalignment of the carrier tape 83 around the Z1 axis can be suppressed. As a result, stable feeding is possible.

[0171] (Embodiment 5) Next, Embodiment 5 of the present disclosure will be described. Figure 30 is a schematic plan view showing the support portion 520e according to Embodiment 5. As shown in Figure 30, a plurality of tape feeding portions 550e are arranged in the direction of travel of the carrier tape 83 on the support portion 520e. Each tape feeding portion 550e is a sprocket, and the teeth 551e of the sprocket engage with the feed holes 88d of the carrier tape 83.

[0172] Thus, even when multiple tape feed units 550e are arranged in a line in the direction of travel, positional misalignment in the width and thickness directions is suppressed, enabling stable feeding of the carrier tape 83. Furthermore, since the teeth 551 of each tape feed unit 550e engage with the feed holes 88d of the carrier tape 83, positional misalignment of the carrier tape 83 around the Z1 axis can be suppressed. As a result, stable feeding is possible.

[0173] (Embodiment 6) Next, Embodiment 6 of the present disclosure will be described. Figure 31 is a plan view showing the cassette gripping portion 400f and the gripped portion 628f according to Embodiment 6. As shown in Figure 31, the pair of opening and closing members 420f provided on the cassette gripping portion 400f are L-shaped members and are provided on the gripping body portion 410f in a position facing each other. The pair of opening and closing members 420f are slidable in the Y-axis direction.

[0174] The gripped portion 628f is a part located on the upper part of the first tape cassette 61. Specifically, the gripped portion 628f is a part that is gripped by a pair of opening / closing members 420f. In other words, the gripped portion 628f is gripped by the pair of opening / closing members 420f as they move closer to each other. The gripped portion 628 has L-shaped notches formed on both sides in the Y-axis direction, and each opening / closing member 420f is inserted into these notches.

[0175] (Embodiment 7) Next, Embodiment 7 of the present disclosure will be described. Figure 32 is a plan view showing the cassette gripping portion 400g and the gripped portion 628g according to Embodiment 7. As shown in Figure 32, each opening and closing member 420g of the cassette gripping portion 400g has a recess 423g formed on its outer surface.

[0176] The gripping portion 628g is a rectangular notch that is elongated in the Y-axis direction and formed at the upper end of the first tape cassette 61. A pair of pin members 629g are formed on the gripping portion 628g. Specifically, each pin member 629g is formed on both end faces of the gripping portion 628g in the Y-axis direction. Each pin member 629g extends along the Y-axis direction. When each opening / closing member 420g moves in the separation direction in a gripping position, each recess 423g engages with each pin member 629g of the gripping portion 628g, and grips the gripping portion 628g.

[0177] (Embodiment 8) Next, Embodiment 8 of the present disclosure will be described. Figure 33 is a plan view showing the cassette gripping section 400h according to Embodiment 8. As shown in Figure 33, a pair of opening / closing members 420h provided on the cassette gripping section 400h are mounted on the gripping body section 410h so as to be able to move up and down. Each opening / closing member 420h becomes a gripping position when it is lowered and a standby position when it is raised. Each opening / closing member 420h supports the gripped section 628 in the gripping position and then moves to the gripping position. On the other hand, each opening / closing member 420h moves to a retracted position in the standby position.

[0178] In this way, even the cassette gripping section 400h, which has a lifting and lowering opening / closing member 420h, can be moved to the retracted position, thus preventing the cassette gripping section 400h from unnecessarily interfering with the first tape cassette 61.

[0179] (others) Although embodiments of the present invention have been described above, the present invention is not limited to these embodiments. 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.

[0180] For example, in each of the above embodiments, the first guide 110 is provided on the component mounting device 20 and the second guide 423 is provided on the tape cassette supply device 40. However, the guide portion may be provided on only one of the component mounting device 20 or the tape cassette supply device 40.

[0181] In the above embodiment, an example was given in which multiple first guides 110 and second guides 423 are provided so as to sandwich one first tape cassette 61. However, one first guide 110 and one second guide 423 may be provided for one first tape cassette 61.
