[0003] [Patent Document 1] Japanese Patent Publication No. 2022-130833 Summary of the Invention [Problem to be solved by the invention]

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

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tape cassette supplying device or the like that can more stably feed out a carrier tape. [Means for solving the problem]

[0006] (1) A tape cassette supplying device according to one aspect of the present invention is a tape cassette supplying device for supplying a tape cassette containing a carrier tape to a component mounting device, and includes a tape support unit that supports the carrier tape and a control unit that controls the tape support unit, wherein the tape support unit includes a pair of gripping members that sandwich the carrier tape in the width direction of the carrier tape, and a regulating unit that regulates movement of the carrier tape in the thickness direction of the carrier tape, and the control unit controls the tape support unit to grip the carrier tape with the pair of gripping members and then regulate movement of the carrier tape in the thickness direction with the regulating unit.

[0007] According to the tape cassette supply device described in (1), after the pair of gripping members grip the carrier tape, the restricting portion restricts the movement of the carrier tape in the thickness direction, thereby suppressing misalignment of the carrier tape in the width direction and the thickness direction. Therefore, the position of the carrier tape can be stabilized, and the carrier tape can be fed out stably.

[0008] (2) In the carrier tape supply device described in (1) above, the tape support unit may include a tape feed unit that feeds the carrier tape in the direction of travel, and the control unit may control the tape support unit so that the tape feed unit feeds the carrier tape in the direction of travel while the pair of gripping members grip the carrier tape and the regulating unit regulates the carrier tape.

[0009] According to the tape cassette supply device described in (2), the carrier tape is gripped by the pair of gripping members and regulated by the regulating unit, and the carrier tape is fed in the direction of travel by the tape feeding unit. In other words, when the carrier tape is fed, positional deviation in the width direction and thickness direction is suppressed, enabling more stable feeding of the carrier tape.

[0010] (3) In the carrier tape supply device described in (2) above, the tape feed section may be a sprocket having a plurality of teeth that engage with feed holes in the carrier tape, and the carrier tape may be fed by rotating the sprocket.

[0011] According to the tape cassette supply device described in (3), 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, thereby further suppressing misalignment of the carrier tape.

[0012] (4) In the carrier tape supplying device described in (2) above, the tape feeding section may be a roller that feeds the carrier tape by rotating in contact with the surface of the carrier tape.

[0013] According to the tape cassette supplying device described in (4), even when the tape feeding section is a roller, positional deviation in the width direction and thickness direction is suppressed, so that stable feeding of the carrier tape is possible.

[0014] (5) In the carrier tape supplying device described in any one of (2) to (4) above, the tape support unit may include a plurality of the tape feed units.

[0015] According to the tape cassette supplying device described in (5), the carrier tape is fed by a plurality of tape feeding sections, so that the carrier tape can be fed more stably.

[0016] (6) In the carrier tape supplying device described in (5) above, the plurality of tape feeding sections may be arranged side by side in the width direction.

[0017] According to the tape cassette supply device described in (6), even when multiple tape feed sections are arranged side by side in the width direction, positional deviation in the width direction and thickness direction is suppressed, thereby enabling stable feeding of the carrier tape.

[0018] (7) In the carrier tape supplying device described in (5) above, the plurality of tape feeding units may be arranged side by side in the traveling direction.

[0019] According to the tape cassette supply device described in (7), even when multiple tape feed sections are arranged side by side in the direction of travel, positional deviation in the width and thickness directions is suppressed, thereby enabling stable feeding of the carrier tape.

[0020] (8) In the carrier tape supplying device described in any one of (2) to (7) above, the pair of gripping members may include curved portions that are curved along the traveling direction.

[0021] According to the tape cassette supply device described in (8), the pair of gripping members have curved portions that are curved along the direction of travel, so that the carrier tape can be stably fed even along a curved path.

[0022] (9) In the carrier tape supplying device described in any one of (1) to (8) above, a detection unit that detects the carrier tape may be provided, and the control unit may control the tape support unit to support the carrier tape based on the detection of the carrier tape by the detection unit.

[0023] According to the tape cassette supplying device described in (9), the tape support section supports the carrier tape based on the detection of the carrier tape by the detection section, so that the carrier tape can be reliably supported.

[0024] (10) Another aspect of the present invention provides a component mounting system comprising: a component mounting device that supports a tape cassette containing a carrier tape; and a tape cassette supply device that supplies the tape cassette to the component mounting device. The tape cassette supply device comprises a tape support unit that supports the carrier tape; and a control unit that controls the tape support unit. The tape support unit has a pair of gripping members that clamp the carrier tape in the width direction of the carrier tape, and a regulating unit that regulates movement of the carrier tape in the thickness direction of the carrier tape. The control unit controls the tape support unit to grip the carrier tape with the pair of gripping members and then regulate movement of the carrier tape in the thickness direction with the regulating unit.

[0025] According to the component mounting system described in (10), after the pair of gripping members grip the carrier tape, the restricting portion restricts the movement of the carrier tape in the thickness direction, thereby suppressing misalignment of the carrier tape in the width direction and the thickness direction. Therefore, the posture of the carrier tape can be stabilized, and the carrier tape can be fed out stably.

[0026] (11) Another aspect of the present invention is a tape feeding method executed by a tape cassette supplying device for supplying a tape cassette containing a carrier tape to a component mounting device, the tape cassette supplying device comprising a pair of gripping members that clamp the carrier tape in the width direction of the carrier tape, and a regulating unit that regulates movement of the carrier tape in the thickness direction of the carrier tape, and the tape feeding method grips the carrier tape with the pair of gripping members and then regulates movement of the carrier tape in the thickness direction with the regulating unit.

[0027] According to the tape feeding method described in (11), after the pair of gripping members grip the carrier tape, the restricting portion restricts the movement of the carrier tape in the thickness direction, thereby suppressing misalignment of the carrier tape in the width direction and the thickness direction. Therefore, the posture of the carrier tape can be stabilized, and the carrier tape can be fed out stably. [Effects of the Invention]

[0028] According to the present invention, the carrier tape can be fed more stably. [Brief explanation of the drawings]

[0030] Hereinafter, with reference to the drawings, a component mounting system according to an embodiment of the present invention and its modified examples will be described. The embodiments and their modified examples described below are comprehensive or specific examples. The numerical values, shapes, materials, components, component placement positions, and connection configurations shown in the following embodiments and their modified examples are merely examples and are not intended to limit the present invention. Furthermore, each figure is a schematic diagram, and dimensions are not necessarily accurately depicted. Furthermore, 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) included in the component mounting system 10, the Y-axis direction is the arrangement direction of each device, 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 attitudes, such as "parallel" and "orthogonal," also include cases where the directions or attitudes are not strictly the same. For example, "two directions are parallel" does not only mean that the two directions are completely parallel, but also means that the two directions are substantially parallel, i.e., that there is a difference of, for example, a few percent. Furthermore, simply referring to the "X-axis direction" means both directions or either one of the directions parallel to the X-axis. The same applies to terms related to the Y-axis and Z-axis.

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

[0033] Component mounting device 20 is a device that mounts components supplied by component supply units 31 provided on carriage 30 onto board 50. Specifically, component mounting device 20 includes component mounting device main body 20a and carriage 30. Component mounting device main body 20a includes head 21 that picks up components 87 (see FIG. 5) on component supply unit 31 of carriage 30 and transfers and mounts them onto board 50, board transport section 22 that transports board 50 on which components 87 have been mounted by head 21 to a downstream reflow device (not shown), and positioning device 23 that positions carriage 30.

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

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

[0036] [Cart] Next, the dolly 30 will be described in detail. Fig. 2 is a plan view showing the dolly 30 and the positioning device 23 according to the first embodiment. Fig. 2 shows a state in which the dolly 30 is separated from the positioning device 23. Fig. 3 is a perspective view showing the dolly 30 according to the first embodiment. Fig. 4 is an explanatory diagram showing a state in which a first tape cassette 61, which is an example of a tape cassette 60, and a second tape cassette 65, which is also an example of a tape cassette 60, have been removed from the dolly 30 according to the first embodiment. Fig. 4 also shows a state in which a first guide 110 provided on the dolly 30 has been removed.

[0037] As shown in FIGS. 2 to 4, the carriage 30 has a component supply unit 31, a plurality of first tape cassette support portions 70, and a carriage body 32 that supports these. The component supply unit 31 has a plurality of feeders 311 (component supply devices) that are arranged in the X-axis direction so as to form pairs with each first tape cassette support portion 70. In FIG. 3, only the feeders 311 at both ends in the X-axis direction are shown. Each feeder 311 pulls out the carrier tape 83 from the tape cassette 60 (first tape cassette 61 or second tape cassette 65) held by the corresponding first tape cassette support portion 70, and transports the components stored on the carrier tape 83 to a pick-up position by the head 21.

[0038] The cart body 32 has a base 300 and a plurality of casters 33 attached to the underside of the base 300, and the plurality of casters 33 allow the cart body 32 to move freely on the floor surface.

[0039] On the base 300, the component supply unit 31 is disposed in the positive direction of the Y axis, and a plurality of first tape cassette support parts 70 are disposed in an array in the X axis direction in the negative direction of the Y axis. For example, a pair of holding walls 34 are erected on the base 300 in the positive direction of the Y axis. Unit holding parts 312 that hold the component supply unit 31 are provided on the pair of holding walls 34 so as to be able to move up and down. Positioning rollers 313 are provided on both ends of the unit holding part 312 in the X axis direction to position each of the holding walls 34 with respect to the positioning device 23.

[0040] A support base 35 that supports a plurality of first tape cassette support portions 70 is disposed on the base 300 in the negative Y-axis direction. A pair of support pillars 351, 352 that are aligned in the Y-axis direction are provided at both ends of the support base 35 in the X-axis direction. A first roller 353 that is positioned relative to the positioning device 23 is provided at the upper end of the support pillar 351 in the positive Y-axis direction. A second roller 354 that is positioned relative to the positioning device 23 is provided at the upper end of the support pillar 352 in the negative Y-axis direction. The first roller 353 and the second roller 354 are aligned along the connection direction of the carriage 30 to the component mounting device 20 (the Y-axis direction).

[0041] The plurality of first tape cassette support parts 70 supported by the support base 35 are each configured to detachably hold the first tape cassette 61 or the second tape cassette 65. The height position of the first tape cassette support parts 70 can be adjusted depending on the tape cassette 60 (first tape cassette 61 or second tape cassette 65) that it supports.

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

[0043] For example, when a first tape cassette 61 is attached to a specific first tape cassette support portion 70, a first receiving device is attached to the specific first tape cassette support portion 70. At this time, in the specific first tape cassette support portion 70, the first tape cassette 61 is disposed in the negative direction of the Y axis, and the first receiving device is disposed in the positive direction of the Y axis.

[0044] On the other hand, when a second tape cassette 65 is attached to a predetermined first tape cassette support portion 70, a second receiving device is attached to that first tape cassette support portion 70. At this time, in the predetermined first tape cassette support portion 70, the second tape cassette 65 is disposed in the negative direction of the Y axis, and the second receiving device is disposed in the positive direction of the Y axis.

[0045] A height adjustment unit (not shown) that adjusts the height position of the support base 35 relative to the base 300 may be provided between the base 300 and the support base 35. In other words, the height adjustment unit adjusts the height of the support base 35, thereby indirectly adjusting the height of the first tape cassette support portion 70.

[0046] [Carrier tape] Fig. 5 is a perspective view showing a schematic configuration of carrier tape 83 constituting roll body 80 according to embodiment 1. As shown in Fig. 5, carrier tape 83 has a tape body 85 having a plurality of component pockets 84, and a cover tape 86 attached to tape body 85 and covering each component pocket 84. Components 87 are stored in component pockets 84. A plurality of feed holes 88 that engage with sprockets of feeder 311 are formed in tape body 85 at positions exposed from cover tape 86. This carrier tape 83 is wound to form roll body 80 (see Fig. 6, etc.).

[0047] [Tape cassette] Next, the tape cassette 60 will be described in detail. The first tape cassette 61 and the second tape cassette 65, which are examples of the tape cassette 60, are different types of tape cassettes. Specifically, the first tape cassette 61, which is a first type, and the second tape cassette 65, which is a second type, differ in that they store rolls 80 with different diameters. For example, the first tape cassette 61 is designed to store a roll 80 with a larger diameter than the second tape cassette 65. Therefore, the first tape cassette 61 itself is also larger than the second tape cassette 65. The size of the roll 80 differs depending on the type of components stored in the carrier tape 83.

[0048] Here, the first tape cassette 61 will be described as an example of 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 section 62, which will be described later, and therefore will not be described again.

[0049] Fig. 6 is an exploded perspective view of a portion of the first tape cassette 61 according to Embodiment 1. As shown in Fig. 6, the first tape cassette 61 includes a storage section 62 and a feeding section 93. The feeding section 93 is a section that feeds the leading end of the carrier tape 83 to the component supply unit 31.

[0050] The first tape cassette 61 has a flat outer shape with its thickness oriented in the X-axis direction, with a feeding section 93 disposed in the positive direction of the Z-axis and a storage section 62 disposed in the negative direction of the Z-axis. The first tape cassette 61 is an example of a tape holding device that holds a carrier tape.

[0051] The storage section 62 has a storage space H1 that stores the roll body 80. Specifically, the storage section 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 generally U-shaped frame that is open in the positive direction of the Y axis when viewed in the X axis direction. The pair of cover bodies 622 are formed as flat plates and are attached to the frame body 621 so as to sandwich the frame body 621 in the X axis direction. As a result, each cover body 622 covers a 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 form the storage space H1. When an unused roll 80 is stored in the storage space H1, the pair of cover bodies 622 completely cover the roll 80. The storage space H1 is open in the positive direction of the Y axis. That is, an opening 623 is provided at the end of the storage section 62 near the component supply unit 31. This opening 623 allows the roll 80 to move freely forward and backward in the Y axis direction relative to the storage space H1. A fall prevention part 624 that prevents the roll 80 from falling out of the opening 623 is provided at the lower end of the frame body 621.

[0053] The distance between the pair of cover bodies 622, i.e., the width (length in the X-axis direction) of the storage space H1, can be freely adjusted according to the width (length in the X-axis direction) of the roll body 80 stored in the storage space H1. For example, the distance between the pair of cover bodies 622 may be adjusted by disposing a spacer (not shown) between each cover body 622 and the frame body 621 so as to avoid the storage space H1. Alternatively, the distance between the pair of cover bodies 622 may be adjusted by interchanging frame bodies 621 with different thicknesses (length in the X-axis direction).

[0054] Fig. 7 is a plan view showing the shape of the lower end portion of the first tape cassette 61 according to the first embodiment. Specifically, as shown in Fig. 7, the lower end portion (the end portion in the negative Z-axis direction) of the frame body 621 of the first tape cassette 61 has a shape that tapers toward the negative Z-axis direction. Furthermore, at the lower end portion of the frame body 621, a first end portion 625 in the positive Y-axis direction has a shape that tapers toward the positive Y-axis direction. In other words, the first end portion 625 is formed in a tapered shape along the facing direction.

[0055] Fig. 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 the first embodiment. Specifically, as shown in Figs. 6 and 8, the end portion of the first tape cassette 61 in the negative Y-axis direction is formed in a stepped shape. Starting from the positive Z-axis direction, these are referred to as a first step portion 626 and a second step portion 627. The first step portion 626 protrudes further 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 each have a shape that tapers toward the negative Y-axis direction (see Fig. 8).

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

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

[0058] 6, 9, and 10, the feed unit 93 is attached to a base unit 930 that is fixed by being sandwiched between the grasped portion 628 and the frame body 621. Specifically, the base unit 930 is a plate-like member that is long in the Y-axis direction, and the feed unit 93 is fixed to the end of the base unit 930 in the positive direction of the Y-axis.

[0059] The feed unit 93 includes 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 of the main body 94 in the X-axis direction. A cam mechanism 96 is also built in the main body 94 so that it can move up and down. An upper end of the cam mechanism 96 protrudes from the top surface of the main body 94. The cam mechanism 96 is slidable back and forth in a direction inclined toward the Z-axis direction (corresponding to the Z1-axis direction described later: see Figure 17). The cam mechanism 96 slides along the normal direction of the carrier tape 83 when the carrier tape 83 is being fed out.

[0060] Furthermore, cam openings 941 that expose a portion of the cam mechanism 96 are formed on both side surfaces of the main body 94 in the X-axis direction. An accommodating recess 942 that accommodates a locking member 97 is formed at the end of the side surface of the main body 94 in the negative X-axis direction, in the positive Y-axis direction, and the locking member 97 is attached within the accommodating recess 942 so as to be able to swing freely.

[0061] The pair of holding members 95 are each made of a single sheet metal. Each holding member 95 includes a fixed portion 951 and a deformable portion 952.

[0062] The fixed portion 951 is a portion fixed to a side surface of the main body portion 94, and is formed in an inverted U shape in a plan view. The deforming portion 952 includes a first portion 953 extending downward from an intermediate portion in the Y-axis direction of the fixed portion 951, a second portion 954 extending in the traveling direction from a lower end portion of the first portion 953, and a third portion 955 extending upward from a tip portion of the second portion 954.

[0063] The first part 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, below the second opening 957, a first support protrusion 959 is provided which is cut and raised toward the carrier tape 83. In this manner, the first support protrusion 959 is disposed below the second opening 957. The first support protrusion 959 has a shape which extends along the traveling direction.

[0065] The second portion 954 is a portion that connects the first portion 953 and the third portion 955, and extends along the traveling direction.

[0066] The third portion 955 is provided with a second support protrusion 960 that is cut and raised toward the carrier tape 83. The second support protrusion 960 has a shape that extends along the traveling direction.

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

[0068] Cam mechanism 96 has cam protrusions 961 on both sides in the X-axis direction, protruding from first opening 956 or second opening 957 (see FIG. 11A, etc.). Cam protrusions 961 are parts for pushing and deforming each holding member 95.

[0069] The following describes the operations of the cam mechanism 96 and each holding member 95. Figures 11A to 11C are explanatory diagrams showing the operations of the cam mechanism 96 and each holding member 95 according to the first embodiment.

[0070] In the state shown in FIG. 11A , the cam protrusions 961 of the cam mechanism 96 are disposed within the first openings 956 and do not push apart the holding members 95. In other words, the holding members 95 are not deformed, and the carrier tape 83 is supported by the first support protrusions 959 of each holding member 95. In this state, the second support protrusions 960 of each holding member 95 also support the carrier tape 83. At this time, the pair of holding members 95 are in a support state in which the support protrusions (the two first support protrusions 959 and the two second support protrusions 960) support the carrier tape 83. In the support state, the fixing portion 951 is not deformed, and therefore the front and rear ends of the fixing portion 951 restrict the movement and rotation of the carrier tape 83 in the width direction. This makes it difficult for the carrier tape 83 to become misaligned. Therefore, external forces from the carrier tape 83 caused by misalignment are suppressed. In other words, the external force that deforms the deforming portion 952 and causes the carrier tape 83 to unexpectedly fall off are suppressed.

[0071] Thereafter, when the drive source operates to lower the cam mechanism 96, the cam protrusions 961 of the cam mechanism 96 contact the partition portions 958 and push the partition portions 958 apart, as shown in FIG. 11B . The cam protrusions 961 are tapered outward to smoothly push the partition portions 958 apart, and the upper and lower surfaces of the cam protrusions 961 are inclined. Pushing the partition portions 958 apart causes the first portions 953 to elastically deform. As a result, the distance between the two first support protrusions 959 becomes wider than 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, and the distance between the two second support protrusions 960 also becomes wider than the width of the carrier tape 83. As a result, the carrier tape 83 falls off. At this time, the pair of holding members 95 are wider in the width direction than the pair of holding members 95 in the supporting state, and are in a released state in which they release their support for the carrier tape 83.

[0072] Here, in the first portion 953, the portion rearward of the first opening 956 in the traveling direction is referred to as a rear portion 9531, and the portion forward is referred to as a front portion 9532. Furthermore, the cross-sectional area of ​​the rear portion 9531 along the traveling direction is referred to as a first cross-sectional area, and the cross-sectional area of ​​the forward portion 9532 along the traveling direction is referred to as a second cross-sectional area. If the first cross-sectional area is larger than the second cross-sectional area, uneven deformation of the first portion 953 occurs, and therefore 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 allows the carrier tape 83 to be more reliably removed.

[0073] Thereafter, when the drive source is operated to further lower the cam mechanism 96, the cam protrusion 961 of the cam mechanism 96 is positioned in the second opening 957, as shown in FIG. 11C . This causes the first portion 953 to elastically return to its original shape. In other words, the pair of holding members 95 return to the supporting state. In this manner, while the cam mechanism 96 slides in one direction, the pair of holding members 95 are transformed from the supporting state to the released state, and then transformed back to the supporting state. Note that the cam mechanism 96 may rise after the released state so that the cam protrusion 961 is positioned in the first opening 956. In this case, the pair of holding members 95 also return to the supporting state. Once the pair of holding members 95 has returned to the supporting state, the carrier tape 83 can be fed again.

[0074] The cam mechanism 96 may also include a push-out portion 962 (shown by the two-dot chain line in FIG. 11B) that pushes out the carrier tape 83 when the pair of holding members 95 are deformed to the released state. The push-out portion 962 is a portion provided 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 push-out portion 962 pushes out the carrier tape 83, allowing the carrier tape 83 to fall off smoothly.

[0075] As shown in FIG. 9 , the locking member 97 is supported in the accommodating recess 942 so as to swing along the traveling direction. The locking member 97 is a generally L-shaped member in a plan view, with its corners serving as the center of swing. The lower end of the locking member 97 enters the feed holes 88 of the carrier tape 83 and locks the feed holes 88. This prevents the carrier tape 83 from shifting in the width direction and traveling direction. Furthermore, the wall 943 of the accommodating recess 942 restricts the lower end of the locking member 97 from swinging in the direction opposite to the traveling direction. In other words, even if the carrier tape 83 attempts to move backward, the locking member 97, which has locked the feed holes 88, does not swing due to the wall 943. In this way, the locking member 97 prevents the carrier tape 83 from moving backward. Furthermore, the locking member 97 has a step 971 located above the lower end that faces the upper surface of the carrier tape 83 when locked in the feed holes 88. This step portion 971 can suppress positional deviation (floating) of the carrier tape 83 in the thickness direction.

[0076] Furthermore, a protruding biasing portion 972 is formed at a corner of the locking member 97. This biasing portion 972 comes into contact with the wall portion 943 of the accommodation recess 942 when the locking member 97 swings in response to the advancement of the carrier tape 83 and its leading end exits the feed hole 88. This contact causes the biasing portion 972 to apply a biasing force to the locking member 97 in the direction opposite to the advancement direction. This causes the locking member 97 to return to its original position, so that the lower end of the locking member 97 enters another feed hole 88 and locks that feed hole 88. The biasing portion 972 may have any shape as long as it biases the locking member 97 in the direction opposite to the advancement direction. An elastic member such as a spring or rubber may also be used as the other biasing portion 972.

[0077] Note that the cam mechanism may have any configuration as long as it can switch between the support state and the release state of the pair of holding members. Fig. 12 is an exploded perspective view of a feed section 93a according to a modified example. Fig. 13 is a cross-sectional perspective view of the feed section 93a according to a modified example. Fig. 13 is a cross-sectional view taken along the direction of travel of the carrier tape 83. In the following description, parts equivalent to those in the configuration described above may be assigned the same reference numerals and their description may be omitted.

[0078] 12 and 13, the feed unit 93a includes 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 the pair of holding members 95a are attached to both side surfaces in the X-axis direction. A cam mechanism 96a is also built into the main body 94a so as to be slidable in the direction of travel.

[0079] The pair of holding members 95a are each made of a single sheet of metal, and each holding member 95a has a fixed portion 951a and a deformable portion 952a.

[0080] The fixed portion 951a is a linear portion fixed to the side surface of the main body portion 94a. The deforming portion 952a includes a first portion 953a that is U-shaped in plan view and extends from both ends of the fixed portion 951a, a second portion 954a that extends in the direction of travel from the lower end of the first portion 953a, and a third portion 955a that extends upward from the tip of the second portion 954a.

[0081] The first part 953a has an opening 956a, and a pair of cam protrusions 966a protruding toward the fixed part 951a is formed on the lower edge of the opening 956a. The pair of cam protrusions 966a are aligned along the traveling direction.

[0082] In the first portion 953a, a first support protrusion 959 that is cut and raised toward the carrier tape 83 is provided below the pair of cam protrusions 966a.

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

[0084] In the cam mechanism 96a, a plurality of cam recesses 967a that accommodate the respective cam protrusions 966a are formed on both side surfaces in the X-axis direction. When each cam protrusion 966a is accommodated in each cam recess 967a, the pair of holding members 95a is in a supported state.

[0085] On the other hand, when the cam mechanism 96a slides and the cam recesses 967a attempt to disengage from the cam protrusions 966a, the cam recesses 967a push the cam protrusions 966a apart, thereby bringing the pair of holding members 95a into the released state.

[0086] Fig. 14 is a front view of a feeding section 93b according to another modified example. As shown in Fig. 14, each holding member 95b has a lifting suppression protrusion 963b arranged above the second support protrusion 960. Specifically, each lifting suppression protrusion 963b is a protrusion cut and raised toward the carrier tape 83. Each lifting suppression protrusion 963b is arranged in a position where it sandwiches the carrier tape 83 together with each second support protrusion 960 in the thickness direction. Each lifting suppression protrusion 963b can suppress lifting of the carrier tape 83 (misalignment in the normal direction).

[0087] [Guide section] 3 and 4, the first guide 110 is an example of a guide portion that guides the tape cassette 60 transferred by the holding portion 43 of the tape cassette supply device 40. In the following description, the first tape cassette 61 is exemplified as the tape cassette 60, but the same applies to the second tape cassette 65.

[0088] The first guide 110 is disposed along the Y-axis direction (the opposing direction of the component mounting device 20 and the tape cassette supply device 40). A plurality of first guides 110 are provided so as to sandwich the first tape cassette 61 supported by the carriage 30 in the X-axis direction. The first guides 110 are detachably attached to the carriage 30. This allows each first guide 110 to be attached at an appropriate position depending on 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 top of the first guide 110, allowing an operator to easily attach and detach the first guide 110. From the viewpoint of workability, it is preferable that the handle 111 be disposed at a position away from both the first tape cassette 61 supported by the first tape cassette support unit 70 and the feeder 311.

[0089] The first guide 110 is a plate-like member that is parallel to the YZ plane and elongated in the Y-axis direction. When attached to the component mounting device 20, the first guide 110 has a size that corresponds to at least the range from the end of the component mounting device 20 in the negative Y-axis direction to the middle of the Y-axis direction. In this embodiment, when attached to the component mounting device 20, the first guide 110 has a size that corresponds to the range from the end of the component mounting device 20 in the negative Y-axis direction to at least the middle of the Y-axis direction. The first guide 110 is also formed to a size that can cover more than half of the range of the first tape cassette 61 and the second tape cassette 65 supported by the first tape cassette support unit 70 as viewed in the X-axis direction. Because the first guide 110 is formed to such a size, it is possible to stably guide the first tape cassette 61 transferred by the holder 43.

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

[0091] The tape cassette supply device 40 has an open end on the positive side of the Y axis, and a pair of connection guides 41 that protrude in the positive direction of the Y axis are provided at this end. These connection guides 41 are members that guide the movement of the tape cassette supply device 40 when the tape cassette supply device 40 is connected to the positioning device 23. Specifically, the connection guides 41 have rollers that roll on the wall surface of the positioning device 23, thereby guiding the movement of the tape cassette supply device 40 when connected.

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

[0093] The support section 42 has a plurality of second tape cassette support sections 421 that individually support each first tape cassette 61, and a mounting base 422 on which the plurality of second tape cassette support sections 421 are placed. Each second tape cassette support section 421 is a slot that extends in the Y-axis direction, and is arranged along the X-axis direction relative to the mounting base 422. In the connected state, each second tape cassette support section 421 faces each first tape cassette support section 70 of the dolly 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), whereby the second tape cassette support portion 421 is aligned with the first tape cassette support portion 70.

[0095] The mounting table 422 is a box-shaped body that is open in the positive Z-axis direction and the positive Y-axis direction, and multiple second tape cassette support units 421 are placed on its bottom. A pair of walls of the mounting table 422 that face each other in the X-axis direction each form 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 when the first tape cassette 61 accommodated therebetween 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 spacing between the pair of second guides 423, only one first tape cassette 61 is accommodated between the pair of second guides 423. Furthermore, in the case of a thin first tape cassette 61, multiple first tape cassettes 61 are accommodated between the pair of second guides 423. The spacing between the pair of second guides 423 may be set so that only one thin first tape cassette 61 is accommodated therebetween. In this case, a plurality of mounting tables 422 may be provided on the support portion 42.

[0096] In the present embodiment, the case where the mounting base 422 made of a box body is provided with a pair of second guides 423 has been exemplified. However, the second guides may be detachable from the tape cassette supplying device 40. In this case, the detachable second guides may be disposed 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] Fig. 16 is a schematic diagram showing a state in which a first tape cassette 61 according to an embodiment is transferred between the tape cassette supplying device 40 and the component mounting device 20. Fig. 16 illustrates the first tape cassette 61, a pair of first guides 110, and a pair of second guides 423 from the positive direction of the Z axis. Fig. 16 illustrates a case in which one first tape cassette 61 is disposed between the pair of first guides 110, and one first tape cassette 61 is disposed between the pair of second guides 423.

[0098] The tape cassette supply device 40 and the component mounting device 20 are preferably arranged along the Y-axis direction. However, due to individual differences between the devices, vibrations during 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. In Figure 16, the misalignment is exaggerated. Even if such misalignment occurs, the first tape cassette 61 is stably guided by the first guide 110 and the second guide 423.

[0099] 16 , for example, suppose that the pair of second guides 423 are arranged along the Y-axis direction, while the pair of first guides 110 are inclined with respect to the Y-axis direction. In this state, the holder 43 transfers the first tape cassette 61 from the component mounting device 20 to the tape cassette supplying device 40. During the transfer, the first tape cassette 61 is guided in the Y-axis direction by the pair of second guides 423, and the first end 625 of the first tape cassette 61 enters the pair of first guides 110. At this time, because the first end 625 has a tapered shape, it smoothly enters the pair of first guides 110. 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 the pair of first guides 110, and the first stage portion 626 and the second stage portion 627 (not shown in FIG. 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 smoothly enter the pair of second guides 423. 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 FIG. 15 , the holding unit 43 is disposed above the support unit 42. The holding unit 43 is moved by a movement mechanism 45 provided in the tape cassette supplying device 40. The movement mechanism 45 moves the holding unit 43 in the X-axis direction, Y-axis direction, and Z-axis direction, and rotates the holding unit 43 around the Z-axis direction. In cooperation with the movement mechanism 45, the holding unit 43 holds the first tape cassette 61 supported by each second tape cassette support unit 421 and supplies it to the component mounting device 20. In cooperation with the movement mechanism 45, the holding unit 43 also holds the first tape cassette 61 supported by each first tape cassette support unit 70 of the component mounting device 20, moves it to the tape cassette supplying device 40, and collects it.

[0102] FIG. 17 is an explanatory diagram showing a schematic configuration of the holding unit 43 according to the first embodiment. As shown in FIG. 17, the holding unit 43 includes a cassette gripping unit 400, a tape support unit 500, and a control unit 600 that controls these. The cassette gripping unit 400 and the tape support unit 500 are integrally configured and aligned in the Y-axis direction. Specifically, the cassette gripping unit 400 is disposed in the positive direction of the Y-axis from the tape support unit 500. The control unit 600 includes a CPU, RAM, and ROM, and the CPU loads a program in the ROM into the RAM and executes it to control the cassette gripping unit 400, the tape support unit 500, the movement mechanism 45, and the drive source of the cam mechanism 96.

[0103] [Cassette gripping part] The cassette gripping portion 400 is a portion that grips the first tape cassette 61. Specifically, the cassette gripping portion 400 includes a gripping main body 410 and a pair of opening / closing members 420. The gripping main body 410 is connected to the moving mechanism 45 and supports the pair of opening / closing members 420. The gripping main body 410 is provided with a cassette sensor (not shown) that detects the first tape cassette 61, and an opening / closing drive unit (not shown) that rotates and slides 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] The pair of open / close members 420 are rotatably and slidably supported by the grip main body 410, and grip the gripped portion 628 of the first tape cassette 61 by rotating and sliding. The pair of open / close members 420 are arranged side by side in the Y-axis direction, and one end of each member is rotatably supported by the grip main body 410. The other end of each pair of open / close members 420 is provided with a pair of pin members 424 that engage with recesses 629 (see FIG. 24, etc.) of the gripped portion 628. As shown in FIG. 17, the state of each open / close member 420 in which each pin member 424 faces upward is the standby position. When each open / close member 420 rotates from the standby position and each pin member 424 faces the Y-axis direction, it is in the grippable position.

[0105] The pair of open / close members 420 are slidable in the Y-axis direction by guide rails 411 provided on the grip main body 410. When in the grippable position, the open / close members 420 are movable in a separating direction in which they move away from each other and in a approaching direction in which they move closer to each other by the guide rails 411. When each open / close member 420 moves in the separating direction in the grippable position, the pin members 424 engage with the recesses 629 of the gripped portion 628, and grip the gripped portion 628 (see FIG. 24).

[0106] [Tape support part] The tape support portion 500 is a portion that supports the carrier tape 83. The tape support portion 500 includes a support connection portion 510 and a support portion 520. The support connection portion 510 is connected to the grip main body portion 410 and supports the support portion 520. An operation drive source (not shown) for operating each operating portion of the support portion 520 is installed in the support connection portion 510. The operation drive source is controlled by the control portion 600. There may be one or more operation drive sources as long as they can operate each operating portion of the support portion 520.

[0107] The support portion 520 is a portion that supports the carrier tape 83 while feeding it out. FIG. 18 is a perspective view showing the support portion 520 according to the first embodiment. FIG. 19 is a cross-sectional view that schematically shows the support portion 520 according to the first embodiment. In FIGS. 18 and 19, the Y1-axis direction is the traveling direction of the carrier tape 83, which is inclined with respect to the Y-axis direction. Strictly speaking, the positive direction of the Y1-axis is the traveling direction, and the negative direction of the Y1-axis is the rear of the traveling direction. The Z1-axis direction is the normal direction of the carrier tape 83, which is inclined with respect to the Z-axis direction (see FIG. 17). The traveling direction and the normal direction are based on a state in which the carrier tape 83 is supported by the support portion 520.

[0108] As shown in FIGS. 18 and 19, the support section 520 includes a pair of gripping members 530, a restricting section 540, a tape feeding section 550, and a detecting section 560.

[0109] The pair of gripping members 530 are members that sandwich 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 is moved in the X-axis direction by an operation drive source (not shown). This causes the distance between the pair of gripping members 530 to vary. Each gripping member 530 is formed from sheet metal, and its lower end is bent inward to form a flat plate portion 531. The flat plate portion 531 is a flat plate that extends along the Y1-axis direction (see FIG. 17). Each flat plate portion 531 supports the carrier tape 83 from below.

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

[0111] The pair of regulating members 541 are capable of moving up and down freely along the Z1-axis direction. The pair of regulating members 541 are raised and lowered by an operation drive source (not shown). When lowering, the flat plate portions 542 of each regulating member 541 approach the carrier tape 83 supported by the flat plate portions 531 of the pair of gripping members 530. This restricts movement (floating) of the carrier tape 83 in the positive direction of the Z1 axis.

[0112] Furthermore, of the pair of regulating members 541, one regulating member 541 in the negative X-axis direction has a support pillar 545 that supports the tape feeding section 550 attached via an elastic member 543 (for example, a spring or rubber). The support pillar 545 is configured to rise and fall together with the one regulating member 541. Furthermore, the support pillar 545 is lowered by a force from an operation drive source (not shown) while resisting the biasing force of the elastic member 543. When the force from the operation drive source is released, the support pillar 545 rises due to the biasing force of the elastic member 543.

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

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

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

[0116] [Tape feeding method] Next, a description will be given of a tape feeding method using the support part 520. Figures 20 to 22 are explanatory diagrams showing the steps of the tape feeding method according to the first embodiment.

[0117] 20, before supporting carrier tape 83, the pair of gripping members 530 are spaced apart to such an extent that they cannot support carrier tape 83. The pair of regulating members 541 are also arranged at a distance corresponding to the distance between the pair of gripping members 530, and are in a raised state.

[0118] When the time comes to support the carrier tape 83, the control unit 600 controls the operating drive source to narrow the gap between the pair of gripping members 530 and the pair of regulating members 541. As a result, the carrier tape 83 is gripped in the width direction (X-axis direction) by the pair of gripping members 530, as shown in Fig. 19. In other words, positional deviation of the carrier tape 83 in the X-axis direction is regulated. The carrier tape 83 is supported from below by the flat plate portions 531 of each gripping member 530.

[0119] Next, the control unit 600 controls the operating drive source to lower the pair of regulating members 541 as shown in FIG. 21 . This brings the flat plate portions 542 of the pair of regulating members 541 closer to the carrier tape 83 supported by the pair of gripping members 530. This restricts movement (floating) of the carrier tape 83 in the positive direction of the Z1 axis. At this time, each flat plate portion 542 is positioned with a slight gap from the upper surface of the carrier tape 83, making it less likely that each flat plate portion 542 will interfere with the feeding of the carrier tape 83. At this time, the control unit 600 may receive a detection signal from the detection unit 560 while controlling the movement mechanism 45 to move the tape support unit 500 along the Y1 axis direction. This allows the control unit 600 to recognize the positions of the feed holes 88 in the carrier tape 83 and position the teeth 551 of the tape feeding unit 550 at positions corresponding to the recognized feed holes 88.

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

[0121] Next, control unit 600 controls the operation drive source to rotate belt 552. This rotates disk 555 and tape feeding unit 550, and carrier tape 83 engaged with teeth 551 is fed in the forward direction. In this manner, with carrier tape 83 gripped by pair of gripping members 530 and carrier tape 83 regulated by regulating unit 540, tape feeding unit 550 feeds carrier tape 83 in the forward direction.

[0122] In this way, in the tape feeding method, the carrier tape 83 is gripped by a pair of gripping members 530, and then the carrier tape 83 is fed in the forward direction while the regulating portion 540 regulates the movement of the carrier tape 83 in the thickness direction.

[0123] [Tape cassette gripping method] Next, a description will be given of a method for holding a tape cassette, which is executed by the holding unit 43. Figures 23 to 26 are explanatory diagrams showing the steps of the method for holding a tape cassette according to the first embodiment.

[0124] Here, a description will be given of the process from when the first tape cassette 61 in the tape cassette supply device 40 is supplied to the carriage 30 to when the carrier tape 83 is then fed from the first tape cassette 61 to the feeder 311.

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

[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 and closing members 420 are positioned above the gripped portion 628 of the first tape cassette 61.

[0127] Next, as shown in FIG. 24, the control unit 600 controls the movement mechanism 45 to lower the holding unit 43 so that the pair of open / close members 420 are positioned within the gripped portions 628. Thereafter, the control unit 600 controls the opening / closing drive unit to slide the pair of open / close members 420 in the separating direction. When each open / close member 420 moves in the separating direction in the grippable position, each pin member 424 engages with each recess 629 of the gripped portion 628, gripping the gripped portion 628 (see FIG. 24). The position of the cassette gripping unit 400 here is the gripping position. The gripping position is the position at which the cassette gripping unit 400 grips the first tape cassette 61. At the gripping position, the tape support unit 500 is separated from the carrier tape 83 held by the feeding unit 93 of the first tape cassette 61.

[0128] After gripping, the control unit 600 controls the movement mechanism 45 to transfer the first tape cassette 61 to the dolly 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, while its first end 625 enters the pair of first guides 110. After entering, the first tape cassette 61 moves to a predetermined position on the dolly 30 while being guided by the pair of first guides 110 (see FIG. 16 ).

[0129] Here, because the cassette gripping portion 400 simply grips the gripped portion 628 of the first tape cassette 61 with the pair of open / close members 420, the first tape cassette 61 may assume an unstable position during transfer. However, because the first tape cassette 61 is guided by the first guides 110 and the second guides 423, the position of the first tape cassette 61 is stabilized. Therefore, it is possible to more stably transfer the first tape cassette 61.

[0130] In particular, when gripped, the first tape cassette 61 is likely 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 be designed to withstand swinging, and the structure of the first tape cassette 61 can be simplified.

[0131] Next, as shown in FIG. 25 , the control unit 600 controls the opening / closing drive unit to slide the pair of opening / closing members 420 in the direction toward each other to release the grip on the gripped portion 628, and then place each opening / closing member 420 in a standby position. After that, the control unit 600 controls the movement mechanism 45 to lower the holding portion 43 so that the tape support portion 500 is positioned so that it can support the carrier tape 83. The position of the cassette gripping portion 400 here is the retracted position. The retracted position is a 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 operating the tape support unit 500 to cause the support unit 520 to grip the carrier tape 83. 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 holding members 95. This causes the carrier tape 83 to fall off the pair of holding members 95 (see FIGS. 11A to 11C). After the carrier tape 83 falls off, the control unit 600 controls the drive source for the cam mechanism 96 to raise the cam mechanism 96 and return the pair of holding members 95 to the supported state.

[0133] Thereafter, the control unit 600 controls the movement mechanism 45 to move the holding unit 43 so that the leading end of the carrier tape 83 is positioned near the feeder 311 (see FIG. 26). In this way, the tape support unit 500 moves while supporting the carrier tape 83, thereby pulling out the carrier tape 83 from the first tape cassette 61. As a result, the carrier tape 83 is pulled out from the first tape cassette 61 to the feeder 311. Note that the carrier tape 83 may be pulled out while still supported by the pair of holding members 95.

[0134] [effect] As described 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 deviation in the width direction and positional deviation in the thickness direction of the carrier tape 83. Therefore, the posture of the carrier tape 83 can be stabilized, and the carrier tape 83 can be fed out stably.

[0135] With the carrier tape 83 gripped by the pair of gripping members 530 and regulated by the regulating unit 540, the carrier tape 83 is fed in the forward direction by the tape feeding unit 550. In other words, since positional deviation in the width direction and thickness direction is suppressed when the carrier tape 83 is fed, the carrier tape 83 can be fed more stably.

[0136] When the carrier tape 83 is fed by the rotation of the sprocket, which is the tape feeding section 550, the teeth 551 of the sprocket engage with the feed holes 88 of the carrier tape 83, thereby further preventing the carrier tape 83 from shifting out of position.

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

[0138] The pair of holding members 95 are configured to be deformable between a supporting state and a releasing state, so that in the supporting state they can support the carrier tape 83, and in the releasing state they can release the support of the carrier tape 83. 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 holding members 95 to deform the pair of holding members 95 between the supported state and the released state, so that the cam mechanism 96 can smoothly deform the pair of holding members 95.

[0140] Since the first cross-sectional area of ​​the portion (rear portion 9531) located rearward of the openings (first opening 956 and second opening 957) of the holding member 95 is larger than the second cross-sectional area of ​​the portion (front portion 9532) located forward of the openings, the amount of deformation of the portion forward of the openings can be made larger than the amount of deformation of the rear portion. This makes it possible to prevent the second support protrusion 960 from interfering with the carrier tape 83 in the released state.

[0141] The sliding movement of the cam mechanism 96a in the direction of advancement allows the pair of holding members 95a to be smoothly switched between the supporting state and the releasing state.

[0142] The sliding movement of the cam mechanism 96 in the normal direction allows the pair of holding members 95 to be smoothly switched between the supporting state and the releasing state.

[0143] While the cam mechanism 96 slides in one direction, the pair of holding members 95 transforms from a supporting state to a releasing state and then transforms again to a supporting state, so that the supporting state can be switched to the releasing state and vice versa by the sliding movement in one direction.

[0144] As the pair of holding members 95 are deformed to the released state, the pushing portions 962 push out the carrier tape 83, so that the carrier tape 83 can be smoothly released from the pair of holding members 95.

[0145] The locking member 97 can prevent misalignment of the carrier tape 83 in the traveling direction. Because the locking member 97 is biased by the biasing portion 972 in the direction opposite to the traveling direction, when the carrier tape 83 is stopped, misalignment in the direction opposite to the traveling direction can be prevented. When the carrier tape 83 advances, the locking member 97 swings against the bias of the biasing portion 972 and disengages from the feed holes 88, so the advancement of the carrier tape 83 is not easily impeded. In other words, the advancement of the carrier tape 83 is permitted while preventing misalignment of the carrier tape 83 in the traveling direction and the opposite direction.

[0146] Since the step portion 971 of the locking member 97 faces the upper surface of the carrier tape 83, it is possible to suppress positional deviation of the carrier tape 83 in the thickness direction.

[0147] The pair of holding members 95 restricts 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), thereby suppressing positional deviation of the carrier tape in the width direction.

[0148] Since the lifting suppression protrusions 963b are disposed at positions where they sandwich the carrier tape 83 together with the second support protrusions 960 in the thickness direction, the lifting of the carrier tape 83 can be suppressed by the lifting suppression protrusions 963b.

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

[0150] Since the cassette gripping portion 400, which has a pair of rotary opening / closing members 420, can also be moved to the retracted position, it is possible to prevent the cassette gripping portion 400 from interfering with the first tape cassette 61 unnecessarily.

[0151] Even in a structure in which the pair of opening and closing members 420 of the cassette gripping portion 400 grip the gripped portion 628 of the first tape cassette 61, it is possible to prevent the cassette gripping portion 400 from interfering unnecessarily with the first tape cassette 61.

[0152] By engaging a pair of pin members 424 with a pair of recesses 629, even in a structure in which a pair of opening / closing members 420 grip the gripped portion 628 of the first tape cassette 61, it is possible to prevent the cassette gripping portion 400 from interfering unnecessarily with the first tape cassette 61.

[0153] When the first tape cassette 61 is supplied to the component mounting device 20, the posture of the first tape cassette 61 is stable. This allows the tape support unit 500 to more accurately support the carrier tape 83. Furthermore, when the first tape cassette 61 is transferred to the component mounting device 20, the tape support unit 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 makes it possible to prevent damage to the carrier tape 83.

[0154] The carrier tape 83 is pulled out from the first tape cassette 61 by the tape support portion 500 moving while supporting the carrier tape 83, so that the carrier tape 83 can be pulled out more stably.

[0155] The first guide 110 and the second guide 423 (guide section) arranged along the Y-axis direction (opposing direction) guide the first tape cassette 61 (tape cassette) transferred by the holding section 43, so that the first tape cassette 61 can be transferred smoothly 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, the first guide 110 and the second guide 423 can be attached at appropriate positions depending on the width of the first tape cassette 61. This makes it possible to improve the convenience of the first guide 110 and the second guide 423.

[0157] The first guide 110 and the second guide 423 are plate-shaped members provided along the Y-axis direction, which increases the contact area between the first guide 110 and the second guide 423 and the first tape cassette 61 during guiding. This allows the first tape cassette 61 to be transferred more stably.

[0158] Since a plurality of first guides 110 and a plurality of second guides 423 are provided so as to sandwich the first tape cassette 61 therebetween, it is possible to transfer one first tape cassette 61 stably.

[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 first tape cassette 61 on the tape cassette supply device 40 side is guided by the second guide 423. Since each movement is stabilized in this way, the transfer of the first tape cassette 61 can be made more stable.

[0160] The pair of open / close members 420 of the cassette gripping portion 400 provided in the holding portion 43 grip the gripped portion 628 of the first tape cassette 61, thereby holding the first tape cassette 61. In this state, the first tape cassette 61 may assume an unstable position during transfer, but the first guide 110 and the second guide 423 guide the first tape cassette 61, so the position of the first tape cassette 61 is stabilized. Therefore, the first tape cassette 61 can be transferred more stably.

[0161] The first tape cassette 61 is held by a pair of pin members 424 provided on the pair of open / close members 420 engaging with a pair of recesses 629 provided in the gripped portion 628. In this case, the first tape cassette 61 is likely to swing around the pair of pin members 424, but the position 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 be designed to withstand swinging, and 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 direction, the first end 625 is less likely to get caught on the guide portion, and the first tape cassette 61 can be guided smoothly.

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

[0164] Fig. 27 is a plan view showing a schematic configuration of a support unit 520b according to embodiment 2. As shown in Fig. 27, the pair of gripping members 530b of the support unit 520b have curved portions 532b at their lower ends that curve along the direction of travel. The curved portions 532b have a convex curved surface that is convex in the positive direction of the Z1 axis. The curved portions 532b of each gripping member 530b support the carrier tape 83 from below.

[0165] In this way, the pair of gripping members 530b has curved portions 532b that curve along the traveling direction, so it is possible to stably feed out the carrier tape 83 even along a curved path. In particular, the bent portion of the carrier tape 84 between the component pockets 84 can easily pass over the ends of the pair of gripping members 530b, allowing for stable feeding.

[0166] (Embodiment 3) Next, a third embodiment of the present disclosure will be described. Fig. 28 is a cross-sectional view schematically showing a support part 520c according to the third embodiment. As shown in Fig. 28, a tape feeding part 550c provided in the support part 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] In this way, even when the tape feeding section 550c is a roller, positional deviation in the width direction and thickness direction is suppressed, so that the carrier tape 83 can be fed out stably.

[0168] (Fourth embodiment) Next, a fourth embodiment of the present disclosure will be described. Fig. 29 is a cross-sectional view schematically showing a support member 520d according to the fourth embodiment. As shown in Fig. 29, the support member 520d is provided with a plurality of tape feed members 550d. The tape feed members 550d are arranged side by side in the width direction of the carrier tape 83d. Each tape feed member 550d is a sprocket. Therefore, the carrier tape 83d is provided with two rows of feed holes 88d with which the sprocket teeth 551d of each tape feed member 550d engage.

[0169] In this way, since the carrier tape 83d is fed by a plurality of tape feeding units 550d, the carrier tape 83d can be fed more stably.

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

[0171] (Embodiment 5) Next, a fifth embodiment according to the present disclosure will be described. Fig. 30 is a plan view schematically showing a support member 520e according to the fifth embodiment. As shown in Fig. 30, a plurality of tape feed members 550e are arranged in the support member 520e in a line in the direction of travel of the carrier tape 83. Each tape feed member 550e is a sprocket, and teeth 551e of the sprocket engage with feed holes 88d of the carrier tape 83.

[0172] In this way, even when multiple tape feed units 550e are arranged side by side in the traveling direction, misalignment in the width and thickness directions is suppressed, enabling stable feeding of the carrier tape 83. Furthermore, the teeth 551 of each tape feed unit 550e engage with the feed holes 88d of the carrier tape 83, suppressing misalignment of the carrier tape 83 around the Z1 axis. These factors enable stable feeding.

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

[0174] The gripped portion 628f is a portion provided on the upper portion of the first tape cassette 61. Specifically, the gripped portion 628f is a portion that is gripped by the pair of open / close members 420f. In other words, the gripped portion 628f is gripped by the pair of open / close members 420f as the pair of open / close members 420f approach each other in the approaching direction. The gripped portion 628f has L-shaped notches formed on both sides in the Y-axis direction, and each open / close member 420f is inserted into this notch.

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

[0176] The gripped portion 628g is a rectangular cutout that is long in the Y-axis direction and is formed in the upper end of the first tape cassette 61. A pair of pin members 629g is formed in the gripped portion 628g. Specifically, each pin member 629g is formed on both end surfaces of the gripped portion 628g in the Y-axis direction. Each pin member 629g extends along the Y-axis direction. When each open-close member 420g moves in the separating direction in the grippable posture, each recess 423g engages with the corresponding pin member 629g of the gripped portion 628g, thereby gripping the gripped portion 628g.

[0177] (Embodiment 8) Next, an eighth embodiment according to the present disclosure will be described. FIG. 33 is a plan view showing a cassette gripping unit 400h according to the eighth embodiment. As shown in FIG. 33, a pair of opening / closing members 420h provided in the cassette gripping unit 400h are provided on a gripping main body 410h so as to be able to move up and down. Each opening / closing member 420h assumes a grippable position by descending, and assumes a standby position by ascending. Each opening / closing member 420h supports a gripped portion 628 in the grippable position, and then moves to a gripping position. Meanwhile, each opening / closing member 420h moves to a retracted position in the standby position.

[0178] In this way, even the cassette gripping portion 400h having the liftable opening / closing member 420h can be moved to the retracted position, so that the cassette gripping portion 400h can be prevented from interfering with the first tape cassette 61 unnecessarily.

[0179] (others) Although the 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 within the meaning and scope of the claims.

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