[0011] Hereinafter, a carrier tape supplying device Y1, a component mounting system X1, and a carrier tape supplying method according to an embodiment will be described with reference to the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, each figure described in the following embodiment is a schematic diagram, and the size and thickness ratios of each component in the figure do not necessarily reflect the actual dimensional ratios.

[0012] (1) Overall Overview First, the carrier tape supplying device Y1 and the component mounting system X1 of the present embodiment will be described with reference to FIGS.

[0013] The carrier tape supplying device Y1 includes a carrier tape supplying device main body Y10 and a moving body M10. The moving body M10 transports the carrier tape supplying device main body Y10. The carrier tape supplying device main body Y10 of this embodiment includes all of the components of the carrier tape supplying device Y1 except for the moving body M10.

[0014] The component mounting system X1 includes a carrier tape supplying device Y1 and a component mounting device Z1.

[0015] The carrier tape supplying device main body Y10 is used together with the component mounting device Z1 and the moving body M10. In addition, the carrier tape supplying device main body Y10 of this embodiment is one device that is moved integrally by the moving body M10. In the following description, the direction in which the carrier tape supplying device Y1 and the component mounting device Z1 are lined up is defined as the left-right direction, the component mounting device Z1 side is defined as the right side as viewed from the carrier tape supplying device Y1, and the carrier tape supplying device Y1 side is defined as the left side as viewed from the component mounting device Z1. In addition, the direction in which multiple feeders 8 (two in FIG. 3) are lined up is defined as the front-rear direction. Furthermore, the direction in which the carrier tape supplying device main body Y10 and the moving body M10 are lined up is defined as the up-down direction, the moving body M10 side is defined as the bottom side as viewed from the carrier tape supplying device main body Y10, and the carrier tape supplying device main body Y10 side is defined as the top side as viewed from the moving body M10. The up and down defined here coincide with the up and down of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 during use.

[0016] The component mounting device Z1 includes a feeder device Z10 and a component mounting device main body Z20 (see FIG. 16). The feeder device Z10 includes a plurality of feeders 8. That is, the component mounting device Z1 includes a plurality of feeders 8. The carrier tape replenishing device Y1 replenishing the carrier tape 6 to each of the plurality of feeders 8. The carrier tape 6 holds components 602 (see FIG. 14B) such as electronic components. The carrier tape 6 is stored in a tape cassette 5. Each feeder 8 has a standby tape holding section 81 that holds a leading end 61 of the carrier tape 6. Each feeder 8 pays out the carrier tape 6. Note that "paying out the carrier tape 6" means to wind the carrier tape 6 and pull it out in order. In other words, "paying out the carrier tape 6" means to perform the reverse operation of winding up the carrier tape 6.

[0017] The carrier tape supplying device main body Y10 is used, for example, in a manufacturing line for manufacturing a circuit board on which a circuit is mounted. The carrier tape supplying device main body Y10 includes a cassette holder 14. The tape cassette 5 taken out from a predetermined storage location and the carrier tape 6 contained in the tape cassette 5 are placed in the cassette holder 14. With the tape cassette 5 and the carrier tape 6 placed in the cassette holder 14, the moving body M10 transports the carrier tape supplying device main body Y10 to the installation location of the component mounting device Z1. Then, the carrier tape 6 is supplied to the feeder 8. The feeder 8 unwinds the carrier tape 6 to supply the component 602 (see FIG. 16) to the component mounting device main body Z20 (see FIG. 16). The component mounting device main body Z20 holds the component 602 held on the carrier tape 6 by means of vacuum suction or the like, and mounts it on the substrate 204 (see FIG. 16) or the like.

[0018] Furthermore, as a result of the carrier tape 6 being supplied to the feeder 8, the tape cassette 5 is left without the carrier tape 6. A tape cassette 5 in this state in which no carrier tape 6 is contained therein is hereinafter referred to as an "empty tape cassette 5." The moving body M10 transports the carrier tape supplying device main body Y10 with the empty tape cassette 5 placed in the cassette holder 14 to a prescribed collection location. At the prescribed collection location, the empty tape cassette 5 is removed from the carrier tape supplying device main body Y10.

[0019] The carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 are used to automatically supply the tape cassette 5 and the carrier tape 6 from the carrier tape supplying device main body Y10 to the component mounting device Z1, supply the components 602 to the component mounting device main body Z20, and collect the empty tape cassette 5. Each of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 includes, for example, a computer system. Each of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 receives a command signal from a management device that manages a manufacturing plan in a factory by wireless communication using radio waves as a medium. Each of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 is controlled in operation by the computer system in response to the command signal from the management device.

[0020] Each of the computer systems of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 has one or more processors and memories. At least some of the functions of the carrier tape supplying device main body Y10, the component mounting device Z1, and the moving body M10 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided through a telecommunication line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0021] (2) Carrier tape supply device (2-1) Overview As shown in Figs. 1 to 3, the carrier tape supplying device Y1 includes a base 11, a positioning unit 2, a carrier tape transfer mechanism TT1, and a floating mechanism 16. The positioning unit 2 regulates the positional relationship between the base 11 and the component mounting device Z1 in the vertical direction. The carrier tape transfer mechanism TT1 is held by the base 11. The carrier tape transfer mechanism TT1 sets the leading end 61 of the carrier tape 6 in the standby tape holding unit 81. The floating mechanism 16 holds the base 11 so that it is movable in the vertical direction.

[0022] According to such a carrier tape supply device Y1, the floating mechanism 16 and the positioning unit 2 can correct an error in the positional relationship between the base 11 and the component mounting device Z1 in the vertical direction. Therefore, the accuracy of the operation of setting (holding) the leading end 61 of the carrier tape 6 in the standby tape holding unit 81 can be improved. In other words, the possibility of failing to set the leading end 61 of the carrier tape 6 in the standby tape holding unit 81 can be reduced.

[0023] Moreover, it is preferable that the carrier tape supply device Y1 further includes a moving body M10. The moving body M10 moves the base 11 to the front of the component mounting device Z1 that requires supply of the carrier tape 6. The floating mechanism 16 holds the base 11 so as to be movable up and down relative to the moving body M10.

[0024] The carrier tape supplying device Y1 supplies the carrier tape 6 to the component mounting device Z1. The component mounting device Z1 has a mounting section (component mounting device main body Z20), a tape cassette holding section 76, and a feeder 8. The mounting section takes out the components 602 from the carrier tape 6 and mounts them on the board 204. The tape cassette holding section 76 detachably holds the tape cassette 5. The tape cassette 5 stores the carrier tape 6. The feeder 8 has a standby tape holding section 81. The feeder 8 pulls in the leading end 61 of the carrier tape 6 set in the standby tape holding section 81 and transports it to a position where the mounting section can take out the components 602. The carrier tape supplying device Y1 has a cassette holder 14, a cassette transfer mechanism TC1, a carrier tape transfer mechanism TT1, and a moving body M10. The cassette holder 14 can hold a plurality of tape cassettes 5. The cassette transfer mechanism TC1 moves the tape cassette 5 storing the carrier tape 6 from the cassette holder 14 to the tape cassette holding section 76. The cassette transfer mechanism TC1 moves the tape cassette 5 that has run out of the carrier tape 6 from the tape cassette holding section 76 to the cassette holder 14. The carrier tape transfer mechanism TT1 sets the leading end 61 of the carrier tape 6 stored in the tape cassette 5 in the standby tape holding section 81. The moving body M10 moves the cassette holder 14, the cassette transfer mechanism TC1, and the carrier tape transfer mechanism TT1 to the front of the component mounting device Z1 that requires replenishment of the carrier tape 6.

[0025] According to such a carrier tape supply device Y1, the leading end 61 of the carrier tape 6 is moved to a fixed position (i.e., to the standby tape holding section 81), thereby improving the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding section 81.

[0026] The carrier tape supply device Y1 includes a cassette holder 14, a cassette transport head 37, a leading end transport head V1, an intermediary unit 151, a first moving mechanism, a second moving mechanism, and a moving body M10. The cassette holder 14 can hold a plurality of tape cassettes 5. The cassette transport head 37 captures the tape cassette 5. The leading end transport head V1 captures the leading end 61 of the carrier tape 6. The intermediary unit 151 relays the tape cassette 5 moving between the cassette holder 14 and the tape cassette holding unit 76. The first moving mechanism moves the cassette transport head 37 and the leading end transport head V1 in the extending direction of the intermediary unit 151 (left-right direction). The second moving mechanism moves the intermediary unit 151 and the first moving mechanism along the arrangement direction of the plurality of tape cassettes 5 in the cassette holder 14 (front-rear direction). The moving body M10 moves the cassette holder 14, the cassette transport head 37, the leading end transport head V1, the relay section 151, the first transport mechanism and the second transport mechanism to the front of the component mounting device Z1 which requires replenishment of the carrier tape 6.

[0027] According to such a carrier tape supply device Y1, the leading end 61 of the carrier tape 6 is moved to a fixed position (i.e., to the standby tape holding section 81), thereby improving the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding section 81.

[0028] The first moving mechanism includes at least the second arm 33, which will be described later, among the components of a first cassette transport mechanism U10 and a first tip transport mechanism W10, which will be described later. The second moving mechanism includes at least the connecting member 154, a slide device 38, and a first arm 32, which will be described later, among the components of a tape transport mechanism T1, which will be described later.

[0029] The component mounting device Z1 also includes a tape cassette holding section 76. A tape cassette 5 that houses a carrier tape 6 is disposed in the tape cassette holding section 76. The carrier tape replenishing device Y1 includes a tape moving mechanism T1 and a cassette holder 14. The tape moving mechanism T1 moves the tape cassette 5. The tape cassette 5 is disposed in the cassette holder 14. The tape moving mechanism T1 transports the carrier tape 6 housed in the tape cassette 5 disposed in the cassette holder 14, and moves the leading end 61 of the carrier tape 6 to the standby tape holding section 81. In this disclosure, "transporting the carrier tape 6" includes directly transporting the carrier tape 6 and indirectly transporting the carrier tape 6 by transporting the tape cassette 5 that houses the carrier tape 6.

[0030] According to such a carrier tape supply device Y1, the leading end 61 of the carrier tape 6 is moved to a fixed position (i.e., to the standby tape holding section 81), thereby improving the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding section 81.

[0031] The carrier tape supplying device Y1 supplies the carrier tape 6 to the component mounting device Z1. The component mounting device Z1 has a mounting section (component mounting device main body Z20), a tape cassette holding section 76, and a feeder 8. The mounting section takes out the components 602 from the carrier tape 6 and mounts them on the board 204. The tape cassette holding section 76 detachably holds the tape cassette 5. The tape cassette 5 stores the carrier tape 6. The feeder 8 has a standby tape holding section 81. The feeder 8 pulls in the leading end 61 of the carrier tape 6 set in the standby tape holding section 81 and transports it to a position where the mounting section can take out the components 602. The carrier tape supplying device Y1 has a cassette holder 14, a cassette transfer mechanism TC1, a carrier tape transfer mechanism TT1, and a moving body M10. The cassette holder 14 can hold a plurality of tape cassettes 5. The cassette transfer mechanism TC1 moves the tape cassette 5 containing the carrier tape 6 from the cassette holder 14 to the tape cassette holding section 76. The cassette transfer mechanism TC1 moves the tape cassette 5 that has run out of the carrier tape 6 from the tape cassette holding section 76 to the cassette holder 14. The carrier tape transfer mechanism TT1 sets the leading end 61 of the carrier tape 6 contained in the tape cassette 5 in the standby tape holding section 81. The moving body M10 moves the cassette holder 14, the cassette transfer mechanism TC1, and the carrier tape transfer mechanism TT1 to the front of the component mounting device Z1 that requires replenishment of the carrier tape 6. The tape cassette 5 has a case 51 and a holding structure 52. The case 51 stores the rolled carrier tape 6. The holding structure 52 holds the leading end 61 of the carrier tape 6. The carrier tape transfer mechanism TT1 takes out the leading end 61 of the carrier tape 6 from the holding structure 52 of the tape cassette 5 replaced by the cassette transfer mechanism TC1, and sets it in the standby tape holding portion 81.

[0032] According to such a carrier tape supply device Y1, when the leading end 61 of the carrier tape 6 is held by the holding structure 52, it becomes easier to perform an operation on the carrier tape 6 (such as clamping or gripping the leading end 61 of the carrier tape 6) to align the leading end 61 of the carrier tape 6, compared to when the leading end 61 is not held by the holding structure 52. Therefore, it is possible to improve the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding part 81.

[0033] The carrier tape supply device Y1 includes a cassette holder 14, a cassette transport head 37, a leading end transport head V1, a guide (relay unit 151), a first moving mechanism, a second moving mechanism, and a moving body M10. The cassette holder 14 can hold a plurality of tape cassettes 5. The cassette transport head 37 captures the tape cassette 5. The leading end transport head V1 captures the leading end 61 of the carrier tape 6. The guide (relay unit 151) extends from the cassette holder 14 to the tape cassette holding unit 76 to guide the movement of the tape cassette 5. The first moving mechanism moves the cassette transport head 37 and the leading end transport head V1 in the extending direction of the guide (relay unit 151) (left-right direction). The second moving mechanism moves the guide (relay unit 151) and the first moving mechanism along the arrangement direction (front-rear direction) of the plurality of tape cassettes 5 in the cassette holder 14. The moving body M10 moves the cassette holder 14, the cassette transport head 37, the leading edge transport head V1, the guide (relay section 151), the first moving mechanism, and the second moving mechanism to the front of the component mounting device Z1 that requires replenishment of the carrier tape 6. The tape cassette 5 has a case 51 and a holding structure 52. The case 51 stores the rolled carrier tape 6. The holding structure 52 holds the leading edge 61 of the carrier tape 6. The leading edge transport head V1 takes out the leading edge 61 of the carrier tape 6 from the holding structure 52 of the tape cassette 5 that is replaced by the cassette transport head 37, and sets it in the standby tape holding section 81.

[0034] According to such a carrier tape supply device Y1, when the leading end 61 of the carrier tape 6 is held by the holding structure 52, it becomes easier to perform an operation on the carrier tape 6 (such as clamping or gripping the leading end 61 of the carrier tape 6) to align the leading end 61 of the carrier tape 6, compared to when the leading end 61 is not held by the holding structure 52. Therefore, it is possible to improve the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding part 81.

[0035] The carrier tape supply device Y1 also includes a tape cassette 5, a cassette holder 14, and a tape movement mechanism T1. The tape cassette 5 accommodates a carrier tape 6. The tape cassette 5 is disposed in the cassette holder 14. The tape movement mechanism T1 transports the carrier tape 6 accommodated in the tape cassette 5 disposed in the cassette holder 14, and moves the carrier tape 6 to a position where it is held by the standby tape holding section 81. The carrier tape 6 has a tape body 60. The tape body 60 is a portion of the carrier tape 6 that is wound around a predetermined portion (a hollow portion in the center). The tape cassette 5 has a case 51 and a holding structure 52. The case 51 accommodates the tape body 60. The holding structure 52 holds a tip portion 61 of the carrier tape 6.

[0036] According to such a carrier tape supply device Y1, when the leading end 61 of the carrier tape 6 is held by the holding structure 52, it becomes easier to perform an operation on the carrier tape 6 (such as clamping or gripping the leading end 61 of the carrier tape 6) to align the leading end 61 of the carrier tape 6, compared to when the leading end 61 is not held by the holding structure 52. Therefore, it is possible to improve the accuracy of the operation of setting the leading end 61 of the carrier tape 6 in the standby tape holding part 81.

[0037] (2-2) Foundation The base 11 of the carrier tape supply device Y1 has a plate-like shape. The base 11 has a rectangular shape in a plan view. The thickness direction of the base 11 is along the up-down direction. The longitudinal direction of the base 11 is along the left-right direction. The lateral direction of the base 11 is along the front-rear direction.

[0038] (2-3) Housing The carrier tape supplying device Y1 further includes a housing 12 and an operation unit 13. The housing 12 is attached to the upper surface of the base 11. The housing 12 has a length in the up-down direction. The housing 12 houses, for example, a computer system that controls the operation of the carrier tape supplying device main body Y10.

[0039] (2-4) Operation section The operation unit 13 is disposed on the outer surface (left side surface) of the housing 12. The operation unit 13 includes a user interface such as a button. A computer system of the carrier tape supplying device main body Y10 controls the operation of the carrier tape supplying device main body Y10 in response to an operation on the operation unit 13.

[0040] (2-5) Tape movement mechanism The carrier tape supply device Y1 includes a tape moving mechanism T1. The tape moving mechanism T1 moves the carrier tape 6 to a position where it is held by the standby tape holding unit 81. The tape moving mechanism T1 includes a cassette transfer mechanism TC1 and a carrier tape transfer mechanism TT1. The cassette transfer mechanism TC1 includes a cassette transfer head 37 and a cassette transport mechanism U1. The carrier tape transport mechanism TT1 includes a leading end transport head V1 and a leading end transport mechanism W1.

[0041] The cassette transport head 37 captures the tape cassette 5. Capturing includes, for example, holding by gripping or the like, and engaging. In this embodiment, the cassette transport head 37 and the tape cassette 5 engage with each other. That is, the tape cassette 5 is captured by the cassette transport head 37 by inserting the holding protrusions 372 of the cassette transport head 37 into the holding holes 5130 formed in the tape cassette 5.

[0042] The cassette transport mechanism U1 moves the cassette transport head 37. The leading edge transport head V1 captures the leading edge 61 of the carrier tape 6. In this embodiment, the leading edge transport head V1 holds the leading edge 61 by pinching it. The leading edge transport mechanism W1 moves the leading edge transport head V1 to move the leading edge 61 of the carrier tape 6 to the standby tape holding section 81. Since the leading edge transport head V1 captures the leading edge 61, the accuracy of the operation of moving the leading edge 61 to the standby tape holding section 81 can be improved compared to the case where the leading edge transport head V1 does not move and pushes out the leading edge 61 to the standby tape holding section 81. Also, the accuracy of the operation of moving the leading edge 61 to the standby tape holding section 81 can be improved compared to the case where the leading edge transport head V1 does not move and pushes out the leading edge 61 to the standby tape holding section 81.

[0043] As shown in FIG. 2, the cassette transport mechanism U1 includes a first cassette transport mechanism U10 and a second cassette transport mechanism U20. The first cassette transport mechanism U10 moves the cassette transport head 37 in a first direction D1. The first direction D1 is the direction in which the base 11 and the component mounting device Z1 are aligned. In this embodiment, the first direction D1 is the left-right direction. The first direction D1 is also the direction in which the cassette holder 14 and the tape cassette holding unit 76 are aligned. The first direction D1 is also the direction in which the cassette holder 14 and the component mounting device Z1 are aligned. The second cassette transport mechanism U20 moves the cassette transport head 37 in a second direction D2 (see FIG. 3). The second direction D2 is a direction that intersects with the first direction D1 and is along a horizontal plane. In this embodiment, the second direction D2 is the front-rear direction.

[0044] The leading edge transport mechanism W1 includes a first leading edge transport mechanism W10 and a second leading edge transport mechanism W20. The first leading edge transport mechanism W10 moves the leading edge transport head V1 in a first direction D1. The second leading edge transport mechanism W20 moves the leading edge transport head V1 in a second direction D2.

[0045] As shown in Figures 3 and 4, the tape movement mechanism T1 has two rails 30, a first slider 31, a first arm 32, a second arm 33, a second slider 34, a third slider 35 (see Figure 8), a fourth slider 36, a cassette transport head 37, a tip transport head V1, a slide device 38, a relay portion 151, and a connecting member 154.

[0046] The cassette transfer mechanism TC1 has a cassette transport mechanism U1 and a cassette transport head 37. The cassette transport mechanism U1 includes two rails 30, a first slider 31, a first arm 32, a second arm 33, a fourth slider 36, a slide device 38, a relay portion 151, and a connecting member 154.

[0047] The cassette transfer mechanism TC1 also functions as at least a part of the carrier tape transfer mechanism TT1. The carrier tape transfer mechanism TT1 has a leading end transfer head V1 and a leading end transport mechanism W1. The leading end transport mechanism W1 includes two rails 30, a first slider 31, a first arm 32, a second arm 33, a second slider 34, a third slider 35, a slide device 38, and a connecting member 154.

[0048] Two rails 30 are attached to the top surface of the housing 12. The two rails 30 each have a length in the front-rear direction. A groove having a length in the front-rear direction is formed in each of the two rails 30. The two rails 30 are arranged in parallel such that the distance between them in the left-right direction is constant.

[0049] The first slider 31 is attached to the two rails 30. That is, a protrusion formed on the first slider 31 is inserted into a groove formed in each rail 30. Therefore, the first slider 31 can move in the front-rear direction while being guided by the two rails 30. The connecting member 154 is connected to the first slider 31. The sliding device 38 is attached to the connecting member 154. The sliding device 38 has a drive mechanism that moves the first slider 31 in the front-rear direction.

[0050] The first arm 32 is attached to the first slider 31. The second arm 33 is attached to the first arm 32, and the second slider 34 is attached to the second arm 33. The tip transfer head V1 is attached to the second slider 34 via the third slider 35. The cassette transfer head 37 is attached to the second arm 33 via the fourth slider 36. Therefore, when the first slider 31 moves in the front-rear direction, the first arm 32, the second arm 33, the second slider 34, the third slider 35, the tip transfer head V1, the fourth slider 36, and the cassette transfer head 37 also move in the front-rear direction together. In other words, at least the first slider 31 is one component of the second cassette transport mechanism U20 that moves the cassette transfer head 37 in the second direction D2 (front-rear direction). At least the first slider 31 is one component of a second leading end transport mechanism W20 that moves the leading end transport head V1 in the second direction D2.

[0051] The first slider 31 is connected to an intermediate portion 151 (guide) that guides the tape cassette 5 via a connecting member 154. Therefore, when the first slider 31 moves in the front-rear direction, the intermediate portion 151 also moves in the front-rear direction together with the first slider 31. The intermediate portion 151 will be described in detail later.

[0052] The positional relationship between the first arm 32 and the first slider 31 is fixed. The first arm 32 has a length in the left-right direction. The first arm 32 extends to the right from the first slider 31. A groove having a length in the left-right direction is formed in the first arm 32. A protrusion provided on the second arm 33 is inserted into this groove. Therefore, the second arm 33 can move in the left-right direction while being guided by the groove. The first arm 32 has a built-in drive mechanism that moves the second arm 33 in the left-right direction. When the second arm 33 moves in the left-right direction, the second slider 34, the third slider 35, the tip transport head V1, the fourth slider 36, and the cassette transport head 37 also move in the left-right direction together. For example, the tip transport head V1 etc. move from the position shown in FIG. 5 to the position shown in FIG. 6. That is, at least the second arm 33 is a component of the first cassette transport mechanism U10 that moves the cassette transport head 37 in the first direction D1 (left-right direction). Also, at least the second arm 33 is a component of the first tip transport mechanism W10 that moves the tip transport head V1 in the first direction D1.

[0053] The second arm 33 has a length in the vertical direction. The second arm 33 extends downward from the first arm 32. A groove having a length in the vertical direction is formed in the second arm 33. A protrusion provided on the second slider 34 is inserted into this groove. Therefore, the second slider 34 can move in the vertical direction while being guided by the groove. When the second slider 34 moves in the vertical direction, the third slider 35 and the tip transport head V1 also move in the vertical direction together. For example, the tip transport head V1 etc. move from the position shown in FIG. 4 to the position shown in FIG. 5.

[0054] The second slider 34 has a rail member 341 (see FIG. 8). The third slider 35 is attached to the rail member 341. More specifically, a groove having a length in the front-rear direction (second direction D2) is formed in the rail member 341. A protrusion provided on the third slider 35 is inserted into this groove. Therefore, the third slider 35 can move in the front-rear direction while being guided by the groove. When the third slider 35 moves in the front-rear direction, the leading end transport head V1 also moves in the front-rear direction together. That is, at least the third slider 35 is one component of the second leading end transport mechanism W20 that moves the leading end transport head V1 in the second direction D2.

[0055] A fourth slider 36 is attached to the second arm 33 (see FIG. 4). The cassette transport head 37 has a main body 371 and a holding protrusion 372. The main body 371 is attached to the fourth slider 36. The positional relationship between the fourth slider 36 and the main body 371 is fixed. The holding protrusion 372 protrudes from the lower end of the main body 371. A groove having a length in the vertical direction is formed in the fourth slider 36. A protrusion provided on the second arm 33 is inserted into this groove. Therefore, the fourth slider 36 can move in the vertical direction together with the cassette transport head 37 while being guided by the groove. When the cassette transport head 37 moves from top to bottom, the holding protrusion 372 is inserted into a holding hole 5130 (see FIG. 15) formed in the tape cassette 5. As a result, the tape cassette 5 is captured by the cassette transport head 37. Conversely, when the cassette transport head 37 moves from bottom to top, the holding protrusion 372 comes out of the holding hole 5130. As a result, the tape cassette 5 is released from the cassette transport head 37.

[0056] The force for driving the first slider 31, the first arm 32, the second arm 33, the second slider 34, the third slider 35 and the fourth slider 36 of the tape movement mechanism T1 can be, for example, the power of a motor and air pressure.

[0057] As described above, the operation of the cassette transport mechanism U1 allows the cassette transfer head 37 to move in three axial directions: up / down, left / right, and front / rear. That is, as the first slider 31 and first arm 32 of the cassette transport mechanism U1 move back and forth, the cassette transfer head 37 moves back and forth. As the second arm 33 moves left and right, the cassette transfer head 37 moves left and right. As the fourth slider 36 moves up and down, the cassette transfer head 37 moves up and down.

[0058] In addition, the tip transfer head V1 can move in three axial directions, up and down, left and right, and front and back, by the operation of the tip transfer mechanism W1. That is, as the first slider 31 and first arm 32 of the tip transfer mechanism W1 move back and forth, the tip transfer head V1 moves back and forth. As the second arm 33 moves left and right, the tip transfer head V1 moves left and right. As the second slider 34 moves up and down, the tip transfer head V1 moves up and down. As the third slider 35 moves back and forth, the tip transfer head V1 moves back and forth. The maximum forward and backward movement distance of the tip transfer head V1 associated with the forward and backward movement of the third slider 35 is shorter than the maximum forward and backward movement distance of the tip transfer head V1 associated with the forward and backward movement of the first slider 31 and first arm 32.

[0059] (2-6) Tip transfer head 7 does not show the front half of the feeder body 80 (housing) of the feeder 8. As shown in FIGS. 7 and 8, the leading end transport head V1 includes a gripping mechanism 41, a feeding mechanism 42, and a motor 43.

[0060] The gripping mechanism 41 includes an upper member 411, a lower member 412, and a driving unit 413. The driving unit 413 includes, for example, an actuator, and moves the lower member 412 up and down. The leading end 61 of the carrier tape 6 is sandwiched between the upper member 411 and the lower member 412. That is, the gripping mechanism 41 sandwiches the leading end 61 of the carrier tape 6 in the thickness direction of the leading end 61. In this way, the gripping mechanism 41 holds the leading end 61 of the carrier tape 6. The upper member 411 has a through hole 4110 for passing the unwinding mechanism 42 therethrough. The lower member 412 has a recess 4120 (see FIG. 15). The space inside the recess 4120 is connected to the space inside the through hole 4110.

[0061] The unwinding mechanism 42 unwinds the leading end 61 of the carrier tape 6 to the standby tape holding section 81 of the feeder 8. The unwinding mechanism 42 moves the leading end 61 relative to the unwinding mechanism 42 by unwinding the leading end 61. As an example, the unwinding mechanism 42 in this embodiment is a sprocket. The unwinding mechanism 42 includes a disk portion 421 and a plurality of teeth 422. The plurality of teeth 422 are arranged at equal intervals on the outer circumferential surface of the disk portion 421. The unwinding mechanism 42 is passed through the through hole 4110 of the upper member 411. In this state, some of the teeth 422 are inserted into some of the feed holes 600 of the plurality of feed holes 600 of the carrier tape 6. Furthermore, the unwinding mechanism 42 rotates by the driving force of the motor 43, whereby the carrier tape 6 is unwound. With leading end 61 of carrier tape 6 facing insertion opening 812 (see FIG. 7) of feeder 8, pay-out mechanism 42 pays out carrier tape 6, thereby inserting leading end 61 into insertion opening 812. Then, carrier tape 6 is held by standby tape holding section 81. Upper member 411 and lower member 412 of gripping mechanism 41 function as guide members that limit the direction of movement of carrier tape 6 to a predetermined direction (to the right).

[0062] The carrier tape supply device Y1 includes an operating body 44 and a support portion 45. The operating body 44 and the support portion 45 are attached to the second arm 33. As an example, the operating body 44 is fixed to the second arm 33 via the support portion 45 so as not to move up and down relative to the second arm 33.

[0063] The operating body 44 includes an arm portion 441, an operating portion 442, and a connecting portion 443. The arm portion 441 has a shape of a long rectangular parallelepiped. The operating portion 442 is attached to one end of the arm portion 441. The other end of the arm portion 441 is supported by the connecting portion 443. The connecting portion 443 is supported by a support portion 45. The support portion 45 is fixed to the second arm 33. The operating portion 442 comes into contact with a release portion 82 (described later) of the feeder 8 and pushes up the release portion 82, thereby releasing the holding of the carrier tape 6 in the standby tape holding portion 81.

[0064] (2-7) Positioning part 9A to 10B, the positioning unit 2 has two insertion arms 21, a plurality of upper rollers 22, and a plurality of lateral rollers 23. Since two upper rollers 22 and two lateral rollers 23 are attached to each of the two insertion arms 21, the positioning unit 2 has a total of four upper rollers 22 and a total of four lateral rollers 23.

[0065] When viewed from the front-rear direction, each of the two insertion arms 21 has an L-shape. The length of each of the two insertion arms 21 in the left-right direction is longer than the length of each of the two insertion arms 21 in the up-down direction. Each of the two insertion arms 21 extends downward from the base 11 and further extends to the right. The two insertion arms 21 are lined up in the front-rear direction. Two upper rollers 22 and two lateral rollers 23 are rotatably attached near the right end of each of the two insertion arms 21. That is, the two upper rollers 22 are lined up on the left and right on the upper surface of each of the two insertion arms 21. In addition, the two lateral rollers 23 are lined up on the left and right on the front surface of the front insertion arm 21 of the two insertion arms 21. The two lateral rollers 23 are lined up on the left and right on the rear surface of the rear insertion arm 21 of the two insertion arms 21.

[0066] (2-8) Power supply unit and air receiving unit 11, the carrier tape supply device Y1 further includes an air receiving unit 171 (receiving unit) and a power receiving unit 172 (receiving unit) that receive a power source supply from the component mounting device Z1. Each of the air receiving unit 171 and the power receiving unit 172 is, for example, a connector connected to the feeder device Z10 of the component mounting device Z1. The air receiving unit 171 provides air (compressed air) supplied from the component mounting device Z1 to, for example, the tape moving mechanism T1 as a power source. The power receiving unit 172 provides power supplied from the component mounting device Z1 to, for example, the tape moving mechanism T1 as a power source.

[0067] (2-9) Floating mechanism An example of the configuration of the floating mechanism 16 will be described with reference to Fig. 12. The floating mechanism 16 is disposed on a moving body M10. The floating mechanism 16 holds the base 11 of the carrier tape supply device Y1 so that it can move in the vertical direction. In other words, the floating mechanism 16 holds the base 11 so that it can move in the vertical direction relative to the moving body M10. More specifically, the floating mechanism 16 supports the base 11 placed on the floating mechanism 16.

[0068] The floating mechanism 16 includes a spring 161 and a spring force adjustment unit 162. The spring 161 is, for example, a compression spring. More specifically, the spring 161 is, for example, a compression coil spring. The direction of expansion and contraction of the spring 161 is along the vertical direction. The spring 161 is sandwiched between the moving body M10 and the base 11 arranged on the moving body M10 via the spring force adjustment unit 162. The spring 161 is compressed by the load of the base 11 and the tape moving mechanism T1 etc. placed on the base 11. When the spring 161 reaches a predetermined length, the load of the base 11 and the tape moving mechanism T1 etc. and the spring force of the spring 161 are balanced. That is, when the height of the base 11 with respect to the floor surface reaches a predetermined height, the load of the base 11 and the tape moving mechanism T1 etc. and the spring force of the spring 161 are balanced.

[0069] The spring force adjustment unit 162 has, for example, an adjustment screw. The adjustment screw is attached to the spring 161. More specifically, the adjustment screw is attached to the lower end of the spring 161. When an operator tightens or loosens the adjustment screw, the spring 161 expands or contracts. This changes the length of the spring 161 when the load of the base 11, the tape moving mechanism T1, etc. and the spring force of the spring 161 are balanced. The adjustment screw may be attached to the upper end of the spring 161.

[0070] (2-10) Cassette holder As shown in FIG. 13, the cassette holder 14 has a support base 140, a plurality of guide rails 141 (first guide rails), a plurality of fixing pins 142, and an attachment member 143.

[0071] The support base 140 includes two legs 1401 and a top plate 1402. The two legs 1401 are attached to the upper surface of the base 11. The top plate 1402 is attached to the upper surfaces of the two legs 1401. The support base 140 is disposed to the right of the housing 12. The multiple guide rails 141 are attached to the upper surface of the top plate 1402. The multiple fixing pins 142 are fixed to the support base 140 via mounting members 143. The multiple fixing pins 142 are disposed on the multiple guide rails 141.

[0072] A tape cassette 5 is placed on each of the multiple guide rails 141. That is, the tape cassette 5 fits into each of the multiple guide rails 141, and the tape cassette 5 is held on the guide rails 141. When the carrier tape supply device Y1 is actually used, it is assumed that tape cassettes 5 are placed on all (or most) of the multiple guide rails 141, but only one tape cassette 5 is shown in the drawing. That is, multiple tape cassettes 5 are placed in the cassette holder 14. And, multiple carrier tapes 6 are housed in the multiple tape cassettes 5.

[0073] The multiple fixing pins 142 correspond one-to-one to the multiple guide rails 141. Each fixing pin 142 is disposed on the corresponding guide rail 141. Each fixing pin 142 is inserted into a fixing hole 5140 (see FIG. 17 ) provided on the left side surface of a tape cassette 5 disposed on the corresponding guide rail 141. In this way, the tape cassette 5 is fixed to the fixing pin 142.

[0074] The carrier tape supplying device Y1 includes a relay portion 151 (second guide rail), a rail 152, a slider 153, and a connecting member 154.

[0075] The relay portion 151 is disposed to the right of the multiple guide rails 141. The rail 152 is attached to the upper surface of the base 11. The rail 152 has a length in the front-rear direction. A groove having a length in the front-rear direction is formed in the rail 152. The slider 153 is attached to the rail 152. That is, a protrusion formed on the slider 153 is inserted into the groove formed in the rail 152. Therefore, the slider 153 is movable in the front-rear direction while being guided by the rail 152.

[0076] Further, the connecting member 154 connects the first slider 31 arranged on the housing 12 to the slider 153. Furthermore, the relay portion 151 is attached to the connecting member 154. Therefore, when the first slider 31 moves in the front-rear direction, the connecting member 154, the slider 153, and the relay portion 151 also move in the front-rear direction together. When the cassette transport head 37 captures the tape cassette 5, the relay portion 151 is located to the right of the guide rail 141 on which the tape cassette 5 captured by the cassette transport head 37 is located, among the multiple guide rails 141. The cassette transport mechanism U1 moves the cassette transport head 37 to move the tape cassette 5 between the guide rail 141 and the relay portion 151.

[0077] Moreover, the tape cassette holding section 76 (see FIG. 10A) of the feeder device Z10 is disposed to the right of the relay section 151. That is, the relay section 151 is disposed between the cassette holder 14 and the tape cassette holding section 76. The cassette transport mechanism U1 moves the tape cassette 5 between the cassette holder 14 and the tape cassette holding section 76 via the relay section 151. In other words, the relay section 151 relays the tape cassette 5 moving between the cassette holder 14 and the tape cassette holding section 76. That is, the tape cassette 5 can be supplied to and collected from the feeder device Z10 via the relay section 151. Furthermore, as described above, the first slider 31 (second cassette transport mechanism U20) moves the relay section 151 together with the cassette transfer head 37 in the second direction D2 (front-rear direction). This allows the tape cassette 5 placed in the relay section 151 to be aligned with respect to the feeder 8 in the second direction D2 (front-rear direction).

[0078] (3) Tape cassette As shown in FIGS. 14A, 15 and 17, the tape cassette 5 has a case 51 and a holding structure 52.

[0079] The case 51 has a first support member 511 (support member), a second support member 512, a first connection portion 513, a second connection portion 514, and a restricting portion 515. The first support member 511 and the second support member 512 are shaped like a plate. The thickness direction of the first support member 511 and the second support member 512 is along the front-rear direction. The first support member 511 and the second support member 512 have a substantially U-shape, for example, formed by providing a recess on one side (right side) of a square.

[0080] The holding structure 52 has two holding parts 520. The two holding parts 520 are supported by the first support member 511. More specifically, the two holding parts 520 are provided at the upper end of the first support member 511. The two holding parts 520 are lined up on the left and right. Each of the two holding parts 520 has a holding part main body 521 and two pins 522. The two pins 522 protrude upward from the holding part main body 521. The two pins 522 are lined up on the left and right. Each of the four pins 522 of the holding structure 52 is inserted into a feed hole 600 formed in the tip part 61. As a result, the two holding parts 520 hold the tip part 61 of the carrier tape 6. In addition, when each of the four pins 522 is removed from the feed hole 600, the holding of the tip part 61 is released. That is, the holding of the tip portion 61 by the holding structure 52 is temporary (temporary fixation). In other words, the holding structure 52 holds the tip portion 61 of the carrier tape 6 in a state in which it can be removed from the holding structure 52.

[0081] The first support member 511 and the second support member 512 face each other in the front-rear direction. Compared to the first support member 511, the second support member 512 has a shape in which a region facing the holding structure 52 in the front-rear direction is removed. Except for the region around the holding structure 52, the first support member 511 and the second support member 512 have approximately the same shape.

[0082] The first supporting member 511 (supporting member) has a recess 5110 at least in a portion between the two holding portions 520. The recess 5110 in this embodiment is a notch formed in the first supporting member 511. The first supporting member 511 does not have an actual structure in an area of ​​the first supporting member 511 that corresponds to the recess 5110. In this embodiment, the recess 5110 is provided between the two holding portions 520, extending from an area adjacent to one holding portion 520 to an area adjacent to the other holding portion 520.

[0083] The first connecting portion 513 and the second connecting portion 514 connect the first supporting member 511 and the second supporting member 512, respectively. The first connecting portion 513 connects the left ends of the first supporting member 511 and the second supporting member 512. The second connecting portion 514 connects the lower ends of the first supporting member 511 and the second supporting member 512. As a result, the shape of the case 51 is a box whose top and right side are open. A fixing hole 5140 into which the fixing pin 142 (see FIG. 13) is inserted is formed on the left side of the second connecting portion 514.

[0084] 17, a holding hole 5130 is formed so as to recess downward from the upper end of the first connecting portion 513. The tape cassette 5 is captured by the cassette transport head 37 by inserting the holding protrusion 372 of the cassette transport head 37 into the holding hole 5130.

[0085] The regulating portion 515 is disposed to the right of the center of the second connecting portion 514. The regulating portion 515 is rotatably attached to the second connecting portion 514. When no force is applied to the regulating portion 515, one end of the regulating portion 515 protrudes into the space between the first supporting member 511 and the second supporting member 512, as shown by the two-dot chain line in FIG. 17. At this time, since the one end of the regulating portion 515 is located to the right of the carrier tape 6, the regulating portion 515 regulates the carrier tape 6 from moving to the right. On the other hand, when a force is applied to the regulating portion 515 from the regulating pin 77 of the component mounting device Z1, the regulating portion 515 is accommodated inside the second connecting portion 514, as shown by the solid line in FIG. 17. This releases the regulation of the carrier tape 6 from moving to the right.

[0086] (4) Carrier tape The carrier tape 6 is formed by winding a strip-shaped member made of paper, polystyrene resin, or the like. The carrier tape 6 does not include a core material (such as a reel) around which the carrier tape 6 is wound, and the carrier tape 6 is stored in the case 51 of the tape cassette 5 by itself. The length direction of the strip-shaped member when the strip-shaped member is stretched in a straight line is defined as the length direction of the carrier tape 6. As shown in FIGS. 14A and 14B, the carrier tape 6 is formed with a plurality of feed holes 600. The plurality of feed holes 600 are arranged at equal intervals in the length direction of the carrier tape 6. The plurality of feed holes 600 are provided from one end to the other end in the length direction of the carrier tape 6. The carrier tape 6 includes a plurality of pockets 601. Each of the plurality of pockets 601 accommodates a component 602 such as an electronic component. The plurality of pockets 601 are arranged at equal intervals in the length direction of the carrier tape 6. The plurality of pockets 601 are provided from one end to the other end in the length direction of the carrier tape 6. A plurality of pockets 601 are arranged in parallel to the plurality of feed holes 600. The carrier tape 6 has a three-layer structure including, for example, a first layer made of a strip-shaped base material having a plurality of pockets 601, a second layer made of a first cover that sandwiches the base material from one side in the thickness direction, and a third layer made of a second cover that sandwiches the base material from the other side in the thickness direction.

[0087] The carrier tape 6 has a tape body 60, a tip portion 61, and an intermediate portion 62. The tape body 60 is a portion of the carrier tape 6 that is wound around a predetermined portion (a hollow portion in the center). The tip portion 61 is a portion that includes one end of the carrier tape 6. The tip portion 61 has a length that is, for example, approximately the same as the distance between the two holding portions 520 of the holding structure 52. The intermediate portion 62 is a portion between the tip portion 61 and the tape body 60. The tip portion 61 and the intermediate portion 62 are unwound from the tape body 60 in advance. In this state, the tip portion 61 is held by the holding structure 52. More specifically, each of the four pins 522 of the holding structure 52 is inserted into a feed hole 600 formed in the tip portion 61. As a result, the tip portion 61 is held by the holding structure 52. Therefore, the position of the portion between the two holding portions 520 of the tip portion 61 is fixed. In particular, the tip portion 61 is held such that the portion between the two holding portions 520 of the holding structure 52 is linear. That is, the tip portion 61 is held in a taut state. The carrier tape 6 is supplied to the carrier tape supply device Y1 with the tip portion 61 held in this manner and the tape body 60 housed in the case 51.

[0088] The tip transport head V1 removes the tip 61 of the carrier tape 6 from the holding structure 52. That is, the gripping mechanism 41 of the tip transport head V1 first clamps the portion of the tip 61 between the two holding parts 520 (see FIG. 15). Since the holding structure 52 holds the tip 61, the position of the portion of the tip 61 between the two holding parts 520 is fixed, so that the gripping mechanism 41 can easily clamp that portion. Thereafter, the tip transport head V1 moves upward, and each of the four pins 522 of the holding structure 52 is disengaged from the feed hole 600, so that the tip 61 is removed from the holding structure 52.

[0089] Before shipping, the carrier tape 6 is wound around a reel R10 (see FIG. 18). As shown in FIG. 18, the reel R10 has two flanges R11 and a core R12. Each of the two flanges R11 is disk-shaped. The core R12 is cylindrical. The two flanges R11 are connected by the core R12. The carrier tape 6 is disposed between the two flanges R11 and wound around the core R12.

[0090] The case 51 stores a roll body (tape body 60) without a reel, with the reel R10 on which the carrier tape 6 was wound at the time of shipment removed. The width L4 of the case 51 is narrower than the width L3 of the reel R10. Therefore, the distance in the front-rear direction between the multiple cases 51 arranged in the cassette holder 14 can be shortened. Therefore, more cases 51 (tape cassettes 5) can be arranged in the cassette holder 14. Moreover, the width L1 of the internal space 500 of the case 51 is narrower than the width L3 of the reel R10. Therefore, the possibility that the carrier tape 6 is mistakenly attached to the reel R10 and stored in the case 51 can be reduced. Moreover, the width L4 of the case 51 is greater than the width L2 of the carrier tape 6.

[0091] The width L1 of the internal space 500 of the case 51 is larger than the width L2 of the carrier tape 6. More specifically, it is desirable that the width L1 of the internal space 500 of the case 51 is slightly larger than the width L2 of the carrier tape 6 so as not to impede the transportation of the carrier tape 6. However, in order to generate friction by contacting the carrier tape 6 with the case 51, the width of the entire or part of the internal space 500 of the case 51 may be slightly smaller than the width L2 of the carrier tape 6. In this case, it is necessary to set the internal space 500 to an appropriate width in consideration of the holding of the tape cassette 5 by the cassette transport head 37.

[0092] (5) Mobile The moving body M10 in this embodiment is an unmanned guided vehicle. A floating mechanism 16 is attached to the upper surface of the moving body M10 (see FIG. 1). On the floating mechanism 16, the components of the carrier tape supply device Y1 other than the floating mechanism 16 and the moving body M10 are placed.

[0093] The moving body M10 includes a motor for generating a driving force and a battery for supplying power to the motor. The moving body M10 may supply the battery power not only to the motor but also to the carrier tape supply device main body Y10.

[0094] The moving body M10 further includes a position detection unit. The position detection unit includes, for example, a receiver that receives a signal from a beacon (transmitter) installed on the travel route of the moving body M10. The position detection unit may also include, for example, a GPS (Global Positioning System) sensor, an obstacle sensor, a camera, and the like. The moving body M10 determines its own position based on information detected by the position detection unit. The moving body M10 transports the carrier tape supplying device main body Y10 in response to a command signal from the management device. As a result, the moving body M10 moves the carrier tape supplying device main body Y10 to the front of the component mounting device Z1 that needs to be replenished with the carrier tape 6. That is, the moving body M10 moves at least the base 11, the positioning unit 2, the carrier tape transport mechanism TT1, and the floating mechanism 16 to the front of the component mounting device Z1 that needs to be replenished with the carrier tape 6.

[0095] (6) Feeder device As shown in Fig. 3 and Fig. 16, the feeder device Z10 includes a plurality of feeders 8 (two in Fig. 3), a supply body 71, a plurality of casters 72 (four in Fig. 3), an intermediate member 73, two connecting members 74, two end tape cassettes 75, two tape cassette holding parts 76, two regulating pins 77, and a position guide member 9. In reality, the feeder device Z10 is assumed to include more than two feeders 8 (for example, 10 or more or 20 or more), but only two feeders 8 are shown in the drawings. In reality, the feeder device Z10 is assumed to include the same number of end tape cassettes 75, tape cassette holding parts 76, and regulating pins 77 as the feeders 8 (for example, 10 or more or 20 or more), but only two end tape cassettes 75, two tape cassette holding parts 76, and two regulating pins 77 are shown in the drawings.

[0096] The supply body 71 occupies the majority of the structural parts of the feeder device Z10. The multiple casters 72 are attached near the lower end of the supply body 71. The multiple casters 72 are the parts of the feeder device Z10 that come into contact with the floor surface. The multiple casters 72 are attached to the supply body 71 by, for example, screwing. By adjusting the screwing position, the height of the supply body 71 (the vertical distance from the floor surface) can be adjusted. In other words, the multiple casters 72 are configured to adjust the height of the supply body 71.

[0097] The multiple feeders 8 are placed on the supply body 71 via intermediate members 73. That is, the intermediate member 73 is disposed on the supply body 71, and the multiple feeders 8 are disposed on the intermediate member 73. Two connecting members 74 are attached to the intermediate member 73. Each of the two connecting members 74 has an L-shape. A position guide member 9 is attached to the two connecting members 74. As a result, the position guide member 9 is fixed to the supply body 71.

[0098] (6-1) Position guide member The positioning portion 2 of the carrier tape supply device Y1 is inserted into a predetermined portion of the position guide member 9. This allows the position guide member 9 to guide the positioning portion 2. This also allows the carrier tape supply device Y1 to be connected to the component mounting device Z1. As shown in FIGS. 9A and 9B, the position guide member 9 has a base portion 90, two first guide members 91, and a second guide member 92.

[0099] The base portion 90 has a plate-like shape. The base portion 90 has a rectangular shape in a plan view. The thickness direction of the base portion 90 is aligned with the up-down direction.

[0100] The two first guide members 91 are disposed at an interval in the front-rear direction. When viewed from the front-rear direction, each of the two first guide members 91 has an L-shape. Each of the two first guide members 91 includes a first member 911 and a second member 912. The first member 911 protrudes upward from the base portion 90. The second member 912 is provided on the first member 911. The second member 912 has a length in the left-right direction. The length of the second member 912 in the front-rear direction is longer than the length of the first member 911 in the front-rear direction.

[0101] The second guide member 92 is disposed between the two first guide members 91. As shown in FIG. 9B, the shape of the second guide member 92 is trapezoidal when viewed from above. The second guide member 92 has two tapered surfaces 920. When viewed from above, the two tapered surfaces 920 are provided in two regions of the second guide member 92 that face the two first guide members 91. More specifically, the two tapered surfaces 920 are provided at the left end of the second guide member 92. Due to the tapered surfaces 920 being provided, the length of the second guide member 92 in the front-rear direction is shorter on the left side when viewed from above.

[0102] When viewed from above, the second member 912 of each of the two first guide members 91 has a tapered surface 9120 in a region facing the second guide member 92. The tapered surface 9120 is provided on the left end of the second member 912. Due to the tapered surface 9120 being provided, when viewed from above, the length of the second member 912 in the front-to-rear direction around the tapered surface 9120 is shorter on the left side.

[0103] 9A, the second member 912 has a tapered surface 9121 in a region (lower surface) facing the base portion 90. The tapered surface 9121 is provided at the left end of the second member 912. Due to the provision of the tapered surface 9121, the vertical length of the second member 912 around the tapered surface 9121 is shorter on the left side when viewed from the front and rear.

[0104] As the movable body M10 moves, the carrier tape supply device main body Y10 approaches the feeder device Z10. As a result, as shown in Figs. 10A and 10B, the positioning unit 2 of the carrier tape supply device main body Y10 is inserted between the two first guide members 91 and the second guide member 92. More specifically, the two insertion arms 21 of the positioning unit 2 correspond one-to-one to the two first guide members 91. Each insertion arm 21 is inserted between the corresponding first guide member 91 and second guide member 92 together with the two upper rollers 22 and the two lateral rollers 23 attached to the insertion arm 21.

[0105] Here, each upper roller 22 is inserted between the second member 912 and the second guide member 92. In the specified region R1 (near the right end of the position guide member 9) where the upper roller 22 is inserted, the distance in the front-rear direction between the second member 912 and the second guide member 92 is slightly longer than the width of the upper roller 22 in the front-rear direction. Therefore, by inserting each upper roller 22 between the second member 912 and the second guide member 92, the positional relationship in the front-rear direction between the base 11 and the feeder device Z10 (component mounting device Z1) is regulated. That is, the positioning unit 2 regulates the positional relationship in the front-rear direction (direction perpendicular to the up-down direction) between the base 11 and the component mounting device Z1.

[0106] Also, when the carrier tape supply device main body Y10 moves to the right so as to approach the feeder device Z10, if the front-rear positioning between the carrier tape supply device main body Y10 and the feeder device Z10 has been performed accurately in advance, the upper roller 22 moves to the specified area R1 without contacting either the tapered surface 9120 or the tapered surface 920. On the other hand, the front-rear positional relationship between the carrier tape supply device main body Y10 and the feeder device Z10 may be shifted, causing the upper roller 22 to contact the tapered surface 9120 or the tapered surface 920. In this case, as the carrier tape supply device main body Y10 moves further to the right, the upper roller 22 moves diagonally forward or backward along the tapered surface 9120 or the tapered surface 920, and moves to the specified area R1. Therefore, the front-rear positional relationship between the base 11 and the feeder device Z10 is the same as that in the case where the front-rear positioning between the carrier tape supply device main body Y10 and the feeder device Z10 has been performed accurately in advance.

[0107] Further, each of the lateral rollers 23 is inserted between the second member 912 and the base portion 90. In the specified region R2 (near the right end of the position guide member 9) into which the lateral rollers 23 are inserted, the vertical distance between the second member 912 and the base portion 90 is slightly longer than the vertical width of the lateral rollers 23. Therefore, by inserting each of the lateral rollers 23 between the second member 912 and the base portion 90, the vertical positional relationship between the base 11 and the feeder device Z10 (component mounting device Z1) is regulated. That is, the positioning unit 2 regulates the vertical positional relationship between the base 11 and the feeder device Z10 (component mounting device Z1).

[0108] Also, when the carrier tape supply device main body Y10 moves to the right so as to approach the feeder device Z10, if the vertical positioning between the carrier tape supply device main body Y10 and the feeder device Z10 has been accurately performed in advance, the horizontal roller 23 moves to the specified area R2 without contacting the tapered surface 9121. On the other hand, the vertical positional relationship between the carrier tape supply device main body Y10 and the feeder device Z10 may be shifted, causing the horizontal roller 23 to contact the tapered surface 9121. In this case, as the carrier tape supply device main body Y10 moves further to the right, the horizontal roller 23 moves obliquely downward along the tapered surface 9121 and moves to the specified area R2. Here, since the floating mechanism 16 holds the base 11 so as to be vertically movable, the base 11 moves vertically relative to the feeder device Z10 due to the contact pressure between the positioning unit 2 and the position guide member 9. Therefore, the vertical positional relationship between the base 11 and the feeder device Z10 is the same as when the vertical positional alignment between the carrier tape supplying device main body Y10 and the feeder device Z10 has been performed accurately in advance.

[0109] In short, the positioning unit 2 includes an adjustment unit. In this embodiment, the multiple horizontal rollers 23 correspond to the adjustment unit. The adjustment unit applies a force to the base 11 to move it vertically before the positional relationship between the base 11 and the component mounting device Z1 in the vertical direction is regulated by the positioning unit 2. In this way, the adjustment unit adjusts the height of the base 11 relative to the component mounting device Z1 to a predetermined reference height. The predetermined reference height is a height determined by the respective structures of the carrier tape supply device Y1 and the component mounting device Z1.

[0110] The adjustment unit is also provided in the positioning unit 2. The adjustment unit moves in one direction (first direction D1) so as to approach the component mounting device Z1. The one direction is a direction along a horizontal plane. One of the adjustment unit and the component mounting device Z1 has a tapered surface that intersects with the horizontal plane, and the other has a contact portion that contacts the tapered surface in the one direction. In this embodiment, the position guide member 9 of the component mounting device Z1 has a tapered surface 9121, and the adjustment unit (horizontal roller 23) has a contact portion (surface of the horizontal roller 23). When the tapered surface 9121 comes into contact with the contact portion, a force in the vertical direction along the tapered surface 9121 is generated between the tapered surface 9121 and the contact portion, and this force moves the base 11 in the vertical direction.

[0111] (6-2) Supply section As shown in FIG. 11, the feeder device Z10 further includes a supply unit 78. The supply unit 78 is attached to the second guide member 92 of the position guide member 9. The supply unit 78 is, for example, a connector connected to the air receiving unit 171 and the power receiving unit 172 of the carrier tape supply device Y1. When the carrier tape supply device Y1 moves to the right so as to approach the feeder device Z10 and the positioning unit 2 is inserted into the position guide member 9, the air receiving unit 171 and the power receiving unit 172 are connected to the supply unit 78 by the kinetic energy of the carrier tape supply device Y1. The component mounting device Z1 supplies air (compressed air) and power to the tape moving mechanism T1 via the supply unit 78, the air receiving unit 171, and the power receiving unit 172.

[0112] (6-3) Termination tape cassette As shown in FIG. 16 and FIG. 17, the end tape cassette 75 is attached to the supply main body 71. A plurality of end tape cassettes 75 (two in this embodiment) are provided. Each end tape cassette 75 is formed in a box shape with a small thickness in the front-rear direction. The end tape cassette 75 has an opening 750 on the left side. The end tape cassette 75 accommodates the carrier tape 6. More specifically, the carrier tape 6 is taken out from the tape cassette 5 transported to the tape cassette holding section 76 by the tape moving mechanism T1. Then, the carrier tape 6 is accommodated in the end tape cassette 75 through the opening 750. The carrier tape 6 transferred from the tape cassette 5 to the end tape cassette 75 is kept in the end tape cassette 75 until it is used up. The feeder 8 supplies the components 602 (see FIG. 14B) held by the carrier tape 6 in the end tape cassette 75 to the component mounting device main body Z20.

[0113] Moreover, it is preferable that the width of the terminating tape cassette 75 is narrower than the width L3 (see FIG. 18) of the reel R10 (see FIG. 18). In this case, it is possible to shorten the distance in the front-rear direction between the multiple feeders 8 provided in one-to-one correspondence with the multiple terminating tape cassettes 75. This allows the component mounting device Z1 to be equipped with a larger number of feeders 8.

[0114] In addition, since the component mounting device Z1 is supplied with a carrier tape 6 without a reel, the distance between the multiple feeders 8 in the front-to-rear direction can be made shorter than when a carrier tape 6 with a reel is supplied.

[0115] (6-4) Tape cassette holder The tape cassette holding portion 76 protrudes from the left end of the last tape cassette 75. Therefore, the same number of tape cassette holding portions 76 as the last tape cassette 75 are provided. The tape cassette holding portions 76 are guide rails, similar to the guide rails 141 of the cassette holder 14. The tape cassette 5 is placed in the tape cassette holding portions 76. That is, the tape cassette holding portions 76 and the tape cassette 5 fit together, and the tape cassette 5 is held on the tape cassette holding portions 76.

[0116] When the carrier tape supply device Y1 and the feeder device Z10 are coupled together by inserting the positioning portion 2 into the position guide member 9 (see FIG. 10A), the guide rail 141 of the cassette holder 14, the relay portion 151, and the tape cassette holding portion 76 are aligned left and right as shown in FIG 2. Therefore, the tape movement mechanism T1 can move the tape cassette 5 left and right to move the tape cassette 5 between the guide rail 141, the relay portion 151, and the tape cassette holding portion 76.

[0117] (6-5) Regulatory pin As shown in Figs. 16 and 17, the regulating pin 77 protrudes from the left end of the terminal tape cassette 75. Therefore, the same number of regulating pins 77 as the terminal tape cassette 75 are provided. The regulating pin 77 operates the regulating portion 515 of the tape cassette 5 moved from the relay portion 151 to the tape cassette holding portion 76. In other words, when the tape cassette 5 moves from the relay portion 151 to the tape cassette holding portion 76, the regulating portion 515 rotates by coming into contact with the regulating pin 77, and as shown by the solid line in Fig. 17, the regulating portion 515 is accommodated inside the second connecting portion 514. This releases the restriction on the carrier tape 6 inside the tape cassette 5 from moving to the right (towards the tape cassette holding portion 76).

[0118] (6-6) Feeder As shown in FIG. 19, the feeder 8 has a feeder body 80, a standby tape holding section 81, a release section 82, a tape running path 83, a discharge port 84, and an outlet 85.

[0119] The standby tape holding section 81 includes a first feed mechanism 811 and an insertion port 812. The first feed mechanism 811 is attached to the feeder body 80. The first feed mechanism 811 is, for example, a sprocket. The first feed mechanism 811 includes a disk portion 8110 and a plurality of teeth 8111. The plurality of teeth 8111 are arranged at equal intervals on the outer circumferential surface of the disk portion 8110. Some of the teeth 8111 are inserted into some of the feed holes 600 (see FIG. 14B) of the carrier tape 6. Furthermore, the leading end 61 of the carrier tape 6 is inserted into the insertion port 812. As a result, the carrier tape 6 is held by the first feed mechanism 811. In addition, the first feed mechanism 811 rotates by the driving force of the motor of the feeder 8. As a result, the first feed mechanism 811 feeds the carrier tape 6. In other words, the first feed mechanism 811 sequentially feeds the carrier tape 6 unwound from the tape main body 60 to the rear (right) of the tape running path 83.

[0120] The insertion port 812 is an opening formed in the feeder body 80. The insertion port 812 is provided near the first feed mechanism 811. The insertion port 812 and the first feed mechanism 811 are provided at the left end of the feeder body 80. The discharge port 84 is provided at the right end of the feeder body 80. The tape running path 83 is a passage inside the feeder body 80. The tape running path 83 connects the insertion port 812 and the discharge port 84. The carrier tape 6 fed by the first feed mechanism 811 is passed through the tape running path 83. The carrier tape 6 enters the tape running path 83 from the insertion port 812 and is discharged to the outside of the feeder body 80 from the discharge port 84. An outlet 85 is provided between the insertion port 812 and the discharge port 84 in the tape running path 83. The outlet 85 is an opening formed in the feeder body 80. The component mounting apparatus main body Z20 (see FIG. 16) takes out the component 602 (see FIG. 16) from the carrier tape 6 through the outlet 85.

[0121] The feeder 8 further includes a second feed mechanism 86 disposed on the tape running path 83. The second feed mechanism 86 is, for example, a sprocket. The second feed mechanism 86 feeds the carrier tape 6.

[0122] The operation unit 442 of the carrier tape supply device Y1 operates the release unit 82 of the feeder 8. The release unit 82 moves the carrier tape 6 held by the standby tape holding unit 81 (first feed mechanism 811) away from the standby tape holding unit 81 (first feed mechanism 811) in response to an operation from the operation unit 442. More specifically, the second arm 33 of the tape moving mechanism T1 and the operation unit 442 fixed to the second arm 33 move to the right, causing the operation unit 442 to push up the release unit 82. The operation of pushing up the release unit 82 causes the first feed mechanism 811 connected to the release unit 82 to move up. As a result, the first feed mechanism 811 moves away from the carrier tape 6, and the holding of the carrier tape 6 by the first feed mechanism 811 is released.

[0123] In short, the release unit 82 releases the leading carrier tape 6 held in the standby tape holding unit 81 from the standby tape holding unit 81. The "leading carrier tape 6" refers to the carrier tape 6 that is held in advance in the standby tape holding unit 81. The operation unit 442 of the carrier tape supply device Y1 operates the release unit 82 before the leading end transport mechanism W1 causes the standby tape holding unit 81 to hold the carrier tape 6 captured by the leading end transport head V1.

[0124] (7) Component mounting device body 16, the component mounting device main body Z20 includes a housing 200, a mounting head 201, a board transport mechanism 202, and a mounting control unit 203. The component mounting device main body Z20 picks up components 602 from a carrier tape 6 fed from a feeder 8, and mounts the components 602 on a board 204.

[0125] The feeder device Z10 is detachably attached to the housing 200. Here, the feeder device Z10 is attached (fixed) to the housing 200. The housing 200 accommodates a mounting head 201, a board transport mechanism 202, and a mounting control unit 203. The board transport mechanism 202 holds a board 204 and transports it to a predetermined position. The mounting head 201 holds a component 602 held on a carrier tape 6 by means of vacuum suction or the like, and mounts the component 602 on the board 204 arranged at the predetermined position. The mounting control unit 203 includes, for example, a computer system. The mounting control unit 203 controls the operation of the mounting head 201 and the board transport mechanism 202.

[0126] (8) Example of operation An example of the operation of a system using the carrier tape supplying device Y1 and the component mounting device Z1 will be described below.

[0127] (8-1) Overview The operations of the carrier tape supplying device Y1 and the component mounting device Z1 are controlled by a management device based on a manufacturing plan for the board 204 on which the components 602 are mounted. For example, a plurality of types of carrier tapes 6 are prepared, and the carrier tapes 6 hold different types of components 602 for each type of tape. The management device then determines which type of carrier tape 6 is to be supplied to which of the plurality of feeders 8. The management device also calculates the remaining length of the carrier tape 6 in each feeder 8 based on, for example, operation information (such as a value obtained by integrating the number of rotations over time) of the first feed mechanism 811 and the second feed mechanism 86 in each feeder 8. The management device instructs the carrier tape supplying device Y1 to perform an operation to supply the carrier tape 6 to the feeder 8 before (or after) the carrier tape 6 is used up.

[0128] The management device, for example, instructs the carrier tape supply device main body Y10 of the coordinates of the destination of each movable component in the tape moving mechanism T1. The origin of the above coordinates is set, for example, on a fixed component (such as the base 11) in the carrier tape supply device main body Y10. Each movable component in the tape moving mechanism T1 is moved to the instructed coordinates.

[0129] (8-2) Adjustment of the floating mechanism Before using the carrier tape supply device Y1 and the component mounting device Z1, the worker uses the spring force adjustment unit 162 to adjust the length of the spring 161 when the load of the base 11 and the tape moving mechanism T1, etc., and the spring force of the spring 161 are balanced. This adjusts the height of the positioning unit 2 from the floor surface so that the positioning unit 2 can be inserted into the position guide member 9 in the next process of "(8-3) Connection". The height of the positioning unit 2 and the base 11 from the floor surface depends on the length of the spring 161, and the length of the spring 161 is finely adjusted in the next process of "(8-3) Connection", so the adjustment using the spring force adjustment unit 162 may be relatively rough. As an example, in the process of "(8-3) Connection", the height can be changed by a maximum of 20 mm. The worker uses the spring force adjustment unit 162 to make the error equal to or smaller than the maximum adjustment width (20 mm). The worker may also adjust the height of the supply body 71 using the multiple casters 72 of the feeder device Z10 as appropriate.

[0130] (8-3) Consolidation As shown in Fig. 1, the initial state is a state in which the carrier tape supplying device Y1 is separated from the component mounting device Z1. The moving body M10 moves so as to approach the component mounting device Z1 with the carrier tape supplying device main body Y10 placed thereon. As a result, the positioning unit 2 is inserted into the position guide member 9 as shown in Fig. 10A and Fig. 10B. That is, the carrier tape supplying device Y1 is connected to the component mounting device Z1 as shown in Fig. 2.

[0131] At this time, when the upper roller 22 of the positioning unit 2 comes into contact with the tapered surface 9120 or the tapered surface 920, the position of the positioning unit 2 is adjusted in the front-rear direction along the tapered surface 9120 or the tapered surface 920. At the same time, the position of the base 11 connected to the positioning unit 2 and the positions of components such as the tape moving mechanism T1 held by the base 11 are adjusted in the front-rear direction.

[0132] Furthermore, when the horizontal roller 23 of the positioning unit 2 comes into contact with the tapered surface 9121, the spring 161 (see FIG. 12) of the floating mechanism 16 expands and contracts, and the position of the positioning unit 2 is adjusted in the vertical direction along the tapered surface 9121. At the same time, the position of the base 11 connected to the positioning unit 2 and the positions of components such as the tape moving mechanism T1 held by the base 11 are adjusted in the vertical direction.

[0133] As a result, the positions of the components such as the base 11 and the tape moving mechanism T1 are fixed. For example, the height of the components such as the tape moving mechanism T1 relative to the feeder device Z10 can be made constant regardless of an error in the height of the moving body M10 or an error in the height of the base 11 relative to the moving body M10.

[0134] (8-4) Moving the tape The tape moving mechanism T1 captures the tape cassette 5 that is placed in the cassette holder 14 and contains the carrier tape 6 with the cassette transport head 37, and moves it to the tape cassette holding section 76 with the cassette transport mechanism U1. More specifically, the cassette transport mechanism U1 removes a specified tape cassette to be removed from the cassette holder 14 among the multiple tape cassettes 5 placed in the cassette holder 14, and moves the specified tape cassette to the tape cassette holding section 76. This operation will be described below.

[0135] When the tape moving mechanism T1 (cassette transport mechanism U1) is operated from a state in which the carrier tape supply device Y1 is connected to the component mounting device Z1, first, as shown in FIG. 2, the holding protrusion 372 (see FIG. 15) of the cassette transport head 37 is inserted into the holding hole 5130 (see FIG. 15) of the tape cassette 5. That is, the cassette transport head 37 captures the tape cassette 5. More specifically, the tape moving mechanism T1 first moves the cassette transport head 37 back and forth so that the holding protrusion 372 is positioned above the tape cassette 5 designated by the management device among the multiple tape cassettes 5 arranged in the cassette holder 14. Thereafter, the tape moving mechanism T1 moves the fourth slider 36 downward to insert the holding protrusion 372 into the holding hole 5130 of the tape cassette 5.

[0136] When the cassette transport head 37 moves back and forth, the relay section 151 also moves back and forth. As a result, the relay section 151 is positioned to the right of the tape cassette 5 captured by the cassette transport head 37 (hereinafter referred to as the "tape cassette 5 during movement").

[0137] Next, the tape moving mechanism T1 moves the second arm 33 to the right. As a result, the tape moving mechanism T1 places the moving tape cassette 5 on the relay section 151. Furthermore, the tape moving mechanism T1 moves the second slider 34 downward as shown in FIG. 4. As a result, the leading end transport head V1 moves to the vicinity of the moving tape cassette 5. In parallel with the operation of moving the second slider 34 downward, the tape moving mechanism T1 moves the third slider 35 (see FIG. 8) back and forth. The upper member 411 and the lower member 412 of the gripping mechanism 41 are separated from each other in advance, and the tape moving mechanism T1 moves the leading end transport head V1 so that the leading end 61 of the carrier tape 6 is positioned between the upper member 411 and the lower member 412. Then, the gripping mechanism 41 drives the lower member 412 to sandwich the leading end 61 between the upper member 411 and the lower member 412 (see FIG. 15). At this time, the lower member 412 passes through the clearance portion 5110 (see FIG. 15) formed between the two holding portions 520 of the moving tape cassette 5 in the front-rear direction, and moves to a position where it sandwiches the leading end portion 61.

[0138] The gripping mechanism 41 of the leading end transport head V1 holds the leading end 61 of the carrier tape 6 arranged in the relay section 151. That is, the operation of the gripping mechanism 41 to clamp (hold) the leading end 61 is performed in a state where the moving tape cassette 5 is in the relay section 151. The reason for this is that if the operation of the gripping mechanism 41 to clamp (hold) the leading end 61 is performed in a state where the tape cassette 5 is in the cassette holder 14, there is a possibility that the cassette transport head 37 will interfere with the tape cassette 5 adjacent to this tape cassette 5 in the front-rear direction. According to this embodiment, it is possible to reduce the possibility of interference between the multiple tape cassettes 5 in the cassette holder 14 and the cassette transport head 37. In addition, since it is not necessary to consider interference by the cassette transport head 37, it is possible to shorten the interval in the front-rear direction between the multiple tape cassettes 5 in the cassette holder 14.

[0139] With the leading end 61 held by the gripping mechanism 41 of the leading end transport head V1, the tape transport mechanism T1 moves the leading end transport head V1 upward, as shown in Fig. 5. This action moves the leading end 61 upward, and the leading end 61 is removed from the two holding parts 520 of the holding structure 52 of the tape cassette 5 being moved. In other words, from a state in which a total of four pins 522 of the two holding parts 520 are inserted into the feed hole 600 of the leading end 61, as the leading end 61 moves upward, the four pins 522 are separated from the feed hole 600.

[0140] Next, the cassette transport mechanism U1 moves the tape cassette 5 to the tape cassette holding section 76 in front of the feeder 8 designated from among the multiple feeders 8. As a result, the tape moving mechanism T1 moves the carrier tape 6 to a position where it is held by the standby tape holding section 81 of the feeder 8 designated from among the multiple feeders 8. More specifically, the tape moving mechanism T1 moves the leading end transport head V1 in the front-rear direction to move the leading end 61 held by the leading end transport head V1 to a position that faces the feeder 8 designated by the management device in the left-right direction among the multiple feeders 8. Next, the tape moving mechanism T1 moves the leading end transport head V1 to the right as shown in FIG. 6. As a result, the tape cassette 5 being moved is disposed above the tape cassette holding section 76. Also, as shown in FIG. 7, the leading end 61 of the carrier tape 6 is disposed near the insertion opening 812.

[0141] The tape moving mechanism T1 causes the carrier tape 6 held by the leading end transport head V1 (hereinafter referred to as the "new carrier tape 6") to be held by the first feed mechanism 811 of the feeder 8. However, the first feed mechanism 811 may hold a carrier tape 6 (hereinafter referred to as the "preceding carrier tape") that is passed through the tape running path 83 of the feeder 8 before the new carrier tape 6. In this case, the tape moving mechanism T1 operates the release section 82 by moving the operation unit 442 to the right, and removes the preceding carrier tape from the first feed mechanism 811. The removed preceding carrier tape is moved to the take-out port 85 and the discharge port 84 by the second feed mechanism 86 (see FIG. 19). After the preceding carrier tape is removed, the tape moving mechanism T1 ends the operation on the release section 82 by moving the operation unit 442 to the left.

[0142] The tape moving mechanism T1 causes the new carrier tape 6 to be held by the first feed mechanism 811 as follows. That is, by rotating the payout mechanism 42 (see FIG. 8) and paying out the carrier tape 6, the leading end 61 of the new carrier tape 6 is moved to the position of the first feed mechanism 811 and is held by the first feed mechanism 811. The new carrier tape 6 held by the first feed mechanism 811 is fed by the first feed mechanism 811 and enters the tape running path 83 (see FIG. 19) from the insertion opening 812.

[0143] Next, the gripping mechanism 41 releases the hold of the new carrier tape 6. That is, the gripping mechanism 41 drives the lower member 412 to separate from the upper member 411.

[0144] When new carrier tape 6 is fed in feeder 8, a force is generated that pulls tape body 60 of the new carrier tape 6. This force causes carrier tape 6 housed in tape cassette 5 arranged in tape cassette holding unit 76 to move to terminal tape cassette 75 (see arrow A1 in FIG. 17), as shown in FIG. 17. In FIG. 17, the carrier tape 6 housed in tape cassette 5 on tape cassette holding unit 76 is shown by a solid line, and the carrier tape 6 housed in terminal tape cassette 75 is shown by a two-dot chain line.

[0145] The empty tape cassette 5 after the carrier tape 6 has been moved to the last tape cassette 75 is moved to the cassette holder 14 by the tape moving mechanism T1. That is, when the carrier tape 6 contained in the tape cassette 5 (the removed tape cassette removed from the cassette holder 14) arranged in the tape cassette holding section 76 runs out, the tape moving mechanism T1 (cassette transport mechanism U1) moves the removed tape cassette to the cassette holder 14. More specifically, the tape moving mechanism T1 (cassette transport mechanism U1) captures the removed tape cassette, which has become an empty tape cassette 5, with the cassette transfer head 37, and moves it to the cassette holder 14 by the cassette transport mechanism U1. More specifically, the tape moving mechanism T1 moves the removed tape cassette from the tape cassette holding section 76 to the cassette holder 14 via the relay section 151.

[0146] (9) Carrier tape supply method A carrier tape supplying method according to the present disclosure will be described with reference to FIG. 20. In one aspect, the carrier tape supplying method using the carrier tape supplying device Y1 includes a positioning step (see "(8-3) Connection") and a moving step (see "(8-4) Tape Movement"). In the positioning step, the positional relationship between the base 11 and the component mounting device Z1 in the vertical direction is regulated. In the moving step, the leading end 61 of the carrier tape 6 is set in the standby tape holding section 81. More specifically, in the moving step, the carrier tape 6 housed in the tape cassette 5 arranged in the cassette holder 14 is moved to move the leading end 61 of the carrier tape 6 to the standby tape holding section 81.

[0147] The positioning step includes step ST1 of moving the carrier tape supply device Y1 to approach the component mounting device Z1, and step ST2 of inserting the positioning unit 2 into the position guide member 9. The moving step includes the following steps ST3 to ST7. In step ST3, the cassette transport head 37 captures the tape cassette 5. In step ST4, the tape cassette 5 is moved together with the cassette transport head 37. As a result, the tape cassette 5 is moved from the cassette holder 14 to the tape cassette holding unit 76. In step ST5, the leading end 61 of the carrier tape 6 is held by the leading end transport head V1. In step ST6, the leading end 61 is moved together with the leading end transport head V1. In step ST7, the leading end 61 is paid out to the standby tape holding unit 81 by the pay-out mechanism 42.

[0148] In one aspect, the carrier tape supply method includes the following first cassette transfer step, second cassette transfer step, carrier tape transfer step, and transport step. In the first cassette transfer step, the tape cassette 5 containing the carrier tape 6 is moved from the cassette holder 14 to the tape cassette holding section 76 (steps ST2 to ST4). The second cassette transfer step is realized by an operation in which the moving direction of the tape cassette 5 is reversed with respect to the first cassette transfer step. In the second cassette transfer step, the tape cassette 5 from which the carrier tape 6 has run out is moved from the tape cassette holding section 76 to the cassette holder 14. In the carrier tape transfer step, the leading end 61 of the carrier tape 6 contained in the tape cassette 5 is set in the standby tape holding section 81 (steps ST5 to ST7). In the transport step, the cassette holder 14 is moved to the front of the component mounting device Z1 that requires the supply of the carrier tape 6 (step ST1).

[0149] In one aspect, the carrier tape supply method includes the following first, second, and third movement steps. In the first movement step, the cassette transport head 37 and the leading end transport head V1 are moved in the extension direction (left-right direction) of the relay portion 151 (steps ST2 to ST4). In the second movement step, the relay portion 151 is moved along the arrangement direction (front-back direction) of the multiple tape cassettes 5 in the cassette holder 14 (step ST4). In the third movement step, the cassette holder 14, the cassette transport head 37, the leading end transport head V1, and the relay portion 151 are moved to the front of the component mounting device Z1 that requires the supply of the carrier tape 6 (step ST1).

[0150] (Variation 1) Hereinafter, the carrier tape supplying device Y1 according to the first modification will be described with reference to Fig. 21. The same components as those in the embodiment will be denoted by the same reference numerals and the description thereof will be omitted.

[0151] In this first modified example, the holding structure 52 of the tape cassette 5 holds the leading end 61 of the carrier tape 6 in a state in which the leading end 61 protrudes to the right beyond the two holding portions 520. Furthermore, when the tape cassette 5 is placed in the relay portion 151 and the tape cassette holding portion 76, the leading end 61 faces the standby tape holding portion 81 in the left-right direction.

[0152] When the leading end 61 is to be held by the first feed mechanism 811 of the standby tape holding section 81, the tape moving mechanism T1 (cassette transfer mechanism TC1) maintains the state in which the leading end 61 is held by the holding structure 52 and moves the leading end 61 to the standby tape holding section 81. More specifically, the tape moving mechanism T1 moves the tape cassette 5 together with the second arm 33 to the right, thereby moving the leading end 61 to the first feed mechanism 811 (see arrow A2). In other words, the leading end 61 can be moved to the standby tape holding section 81 by moving the tape cassette 5, without the need to hold the leading end 61 by the leading end transfer head V1 (see FIG. 1).

[0153] Here, as an example, a case will be described in which the leading end 61 moves to the standby tape holding section 81 as a result of the tape cassette 5 moving in the relay section 151 and the tape cassette holding section 76. However, the leading end 61 may also move to the standby tape holding section 81 as a result of the tape cassette 5 moving in the relay section 151.

[0154] As the tape cassette 5 moves through the relay section 151 and the tape cassette holding section 76, the leading end 61 moves to the standby tape holding section 81, and then the holding of the carrier tape 6 by the holding structure 52 is released. For example, by lowering the tape cassette holding section 76 by the power of a motor or the like, each of the four pins 522 (see FIG. 14A) comes out of the feed holes 600 (see FIG. 14A) of the carrier tape 6, and the holding of the leading end 61 is released. Alternatively, the leading end transport head V1 lifts up a portion of the carrier tape 6 between the two holding sections 520, thereby releasing the holding of the leading end 61.

[0155] In another embodiment, the tape cassette 5 containing the carrier tape 6 may be held in the feeder device Z10 until the carrier tape 6 is used up. Furthermore, the state in which the carrier tape 6 is held in the holding structure 52 may be maintained until the carrier tape 6 is used up. In this embodiment, each of the two holding units 520 is formed of, for example, a payout mechanism such as a sprocket. The carrier tape 6 is held in the holding unit 520 (sprocket) by inserting a plurality of teeth of the holding unit 520 (sprocket) into a plurality of feed holes 600 of the carrier tape 6. The holding unit 520 (sprocket) rotates, and the carrier tape 6 is supplied to the feeder 8 while being held in the holding unit 520 (sprocket).

[0156] Furthermore, when each of the two holding parts 520 is configured with a payout mechanism such as a sprocket, the leading end 61 can be moved to the standby tape holding part 81 as follows. First, the tape moving mechanism T1 brings the tape cassette 5 closer to the standby tape holding part 81. Thereafter, the holding part 520 (sprocket) rotates to pay out the leading end 61 of the carrier tape 6, thereby moving the leading end 61 to the standby tape holding part 81. The holding part 520 (sprocket) may be rotated by being powered, or the leading end transport head V1 may move the leading end 61 to the right, thereby rotating the holding part 520 (sprocket).

[0157] Furthermore, instead of configuring the two holding parts 520 with a pay-out mechanism such as a sprocket, a pay-out mechanism may be provided separately from the two holding parts 520. The carrier tape 6 may be maintained in a state held by the two holding parts 520, and the leading end 61 may be moved to the standby tape holding part 81 by the pay-out mechanism. Alternatively, the leading end 61 of the carrier tape 6 may be removed from the two holding parts 520, and then the leading end 61 may be moved to the standby tape holding part 81 by the pay-out mechanism.

[0158] Furthermore, in this modified example 1, the leading end transport head V1 may remove the leading end 61 of the carrier tape 6 from the holding structure 52, and then move the leading end 61 to the standby tape holding section 81. In this case, compared to the embodiment, the difference in height from the floor surface between the leading end 61 held in the tape cassette 5 and the standby tape holding section 81 is small (a predetermined value or less), so that the accuracy of the operation of moving the leading end 61 to the standby tape holding section 81 can be improved.

[0159] In addition, the carrier tape supply device Y1 may be capable of both removing the tip portion 61 of the carrier tape 6 from the holding structure 52 and then moving the tip portion 61 to the standby tape holding section 81, and maintaining the tip portion 61 held in the holding structure 52 and moving the tip portion 61 to the standby tape holding section 81.

[0160] (Other Modifications of the Embodiments) Other variations of the embodiment are listed below. The following variations may be implemented in appropriate combination. The following variations may also be implemented in appropriate combination with the above-mentioned variation 1.

[0161] The cassette transport mechanism U1 that moves the cassette transport head 37 may be provided separately from the leading end transport mechanism W1 that moves the leading end transport head V1. To achieve this, for example, the carrier tape supply device Y1 may include the following first tape transport mechanism and second tape transport mechanism. The first tape transport mechanism is a configuration in which the cassette transport head 37 is omitted from the configuration of the tape transport mechanism T1 of the embodiment. The second tape transport mechanism is a configuration in which the leading end transport head V1 is omitted from the configuration of the tape transport mechanism T1 of the embodiment. In this case, the first tape transport mechanism includes the leading end transport head V1 and the leading end transport mechanism W1. The second tape transport mechanism includes the cassette transport head 37 and the cassette transport mechanism U1. For example, the first tape transport mechanism and the second tape transport mechanism may be arranged in front and behind on the base 11.

[0162] The number of holding portions 520 that the holding structure 52 has is not limited to two, and may be one, or three or more.

[0163] In the embodiment, the moving body M10 is included in the configuration of the carrier tape supplying device Y1, but the moving body M10 does not have to be included in the configuration of the carrier tape supplying device Y1.

[0164] In the embodiment, the carrier tape 6 and the tape cassette 5 are not included in the configuration of the carrier tape supplying device Y1, but at least one of the carrier tape 6 and the tape cassette 5 may be included in the configuration of the carrier tape supplying device Y1.

[0165] The carrier tape 6 may be wound on a reel. The reel may be fixed to the tape cassette 5, or may be detachable from the tape cassette 5.

[0166] The holding structure 52 may be configured as a gripping mechanism that clamps the tip portion 61 of the carrier tape 6 by the spring force of a spring or the like. Alternatively, the holding structure 52 may be configured as a crimping portion to which the tip portion 61 of the carrier tape 6 is crimped. Alternatively, the holding structure 52 may be configured as an adhesive portion that is bonded to the tip portion 61 of the carrier tape 6 via an adhesive.

[0167] Rollers may be used instead of sprockets as components of the payout mechanism 42, the first feed mechanism 811, and the second feed mechanism 86 that pay out the carrier tape 6. The rollers transmit power to the carrier tape 6 by frictional force generated between the rollers and the carrier tape 6, and pay out the carrier tape 6.

[0168] The tape cassette 5 may be distributed on the market as a single tape cassette 5, separate from other components of the carrier tape supply device Y1. Therefore, the configuration of the tape cassette 5 of the present disclosure may be realized in a state where it is not incorporated into the carrier tape supply device Y1.

[0169] The feeder apparatus Z10 may be distributed on the market as a single feeder apparatus Z10, separate from the component mounting apparatus main body Z20. Alternatively, the feeder apparatus Z10 may be distributed on the market together with at least a part of the configuration of the carrier tape supply apparatus Y1, separate from the component mounting apparatus main body Z20. Therefore, the configuration of the feeder apparatus Z10 of the present disclosure may be realized independently of the component mounting apparatus main body Z20. The spring 161 of the floating mechanism 16 is not limited to a coil spring, and may be, for example, an air spring.

[0170] The carrier tape supply device Y1 may be provided with a remote operation mechanism for remotely operating the spring force adjustment unit 162 of the floating mechanism 16. The remote operation mechanism includes, for example, an actuator for tightening or loosening the adjustment screw of the spring force adjustment unit 162, a control circuit for controlling the operation of the actuator, and a receiving unit for receiving an instruction signal related to the remote operation and transmitting the signal to the control circuit.

[0171] The positioning unit 2 of the embodiment regulates the positional relationship between the base 11 and the component mounting device Z1 in the up-down and front-rear directions. Here, "regulating the positional relationship" does not mean that the base 11 is fixed so as not to move, but only that the distance over which the base 11 can move is limited to a predetermined distance or less. The predetermined distance is, for example, about 1 mm or a few mm.

[0172] The moving body M10 of the embodiment is an unmanned guided vehicle that has wheels and moves on a floor surface by rotating the wheels. However, the moving body M10 may be, for example, an unmanned guided vehicle that moves on rails. Furthermore, the moving body M10 is not limited to an unmanned guided vehicle. The moving body M10 may be, for example, a conveyor device that transports the carrier tape supply device main body Y10. Furthermore, the moving body M10 is not limited to a self-propelled device, and may be a device (cart) that can move by being towed.

[0173] In the embodiment, the floating mechanism 16 is provided in the carrier tape supply device Y1, but the component mounting device Z1 may also be provided with the floating mechanism 16. That is, the component mounting device Z1 may also be provided with the floating mechanism 16 that holds the feeder 8 movably in the vertical direction.

[0174] (summary) The above-described embodiments and the like disclose the following aspects.

[0175] The carrier tape supply device (Y1) according to the first aspect supplies a carrier tape (6) to a component mounting device (Z1). The component mounting device (Z1) has a mounting unit (component mounting device main body (Z20)), a tape cassette holding unit (76), and a feeder (8). The mounting unit removes a component (602) from the carrier tape (6) and mounts it on a board (204). The tape cassette holding unit (76) detachably holds a tape cassette (5). The tape cassette (5) stores the carrier tape (6). The feeder (8) has a standby tape holding unit (81). The feeder (8) pulls in a leading end (61) of the carrier tape (6) set in the standby tape holding unit (81) and transports it to a position where the mounting unit can remove the component (602). The carrier tape supply device (Y1) includes a cassette holder (14), a cassette transfer mechanism (TC1), a carrier tape transfer mechanism (TT1), and a moving body (M10). The cassette holder (14) is capable of holding a plurality of tape cassettes (5). The cassette transfer mechanism (TC1) moves the tape cassette (5) containing the carrier tape (6) from the cassette holder (14) to the tape cassette holding section (76). The cassette transfer mechanism (TC1) moves the tape cassette (5) from which the carrier tape (6) has run out from the tape cassette holding section (76) to the cassette holder (14). The carrier tape transfer mechanism (TT1) sets the leading end (61) of the carrier tape (6) contained in the tape cassette (5) in the standby tape holding section (81). The moving body (M10) moves the cassette holder (14), the cassette transfer mechanism (TC1), and the carrier tape transfer mechanism (TT1) to the front of the component mounting device (Z1) that requires replenishment of the carrier tape (6). The tape cassette (5) has a case (51) and a holding structure (52). The case (51) stores the rolled carrier tape (6). The holding structure (52) holds the leading end (61) of the carrier tape (6). The carrier tape transfer mechanism (TT1) takes out the leading end (61) of the carrier tape (6) from the holding structure (52) of the tape cassette (5) replaced by the cassette transfer mechanism (TC1) and sets it in the standby tape holding section (81).

[0176] According to the above configuration, when the leading end (61) of the carrier tape (6) is held by the holding structure (52), it is easier to perform operations on the carrier tape (6) (such as clamping or gripping the leading end (61) of the carrier tape (6)) compared to when the leading end (61) is not held by the holding structure (52). This makes it possible to improve the accuracy of the operation of setting the leading end (61) of the carrier tape (6) in the standby tape holding section (81).

[0177] In the carrier tape supply device (Y1) according to the second aspect, in the first aspect, the cassette transfer mechanism (TC1) has a cassette transfer head (37) and a cassette transport mechanism (U1). The cassette transfer head (37) captures the tape cassette (5). The cassette transport mechanism (U1) moves the cassette transfer head (37).

[0178] According to the above configuration, the carrier tape (6) can be moved together with the tape cassette (5).

[0179] In the carrier tape supply device (Y1) according to the third aspect, in the second aspect, the cassette transport mechanism (U1) includes a first cassette transport mechanism (U10) and a second cassette transport mechanism (U20). The first cassette transport mechanism (U10) moves the cassette transport head (37) in a first direction (D1). The first direction (D1) is the direction in which the cassette holder (14) and the tape cassette holding portion (76) are aligned. The second cassette transport mechanism (U20) moves the cassette transport head (37) in a second direction (D2). The second direction (D2) is a direction that intersects with the first direction (D1) and is along a horizontal plane.

[0180] According to the above configuration, the tape cassette (5) can be moved in two directions, the first direction (D1) and the second direction (D2).

[0181] Moreover, the carrier tape supply device (Y1) according to the fourth aspect is the third aspect, and further includes an intermediate portion (151). The intermediate portion (151) is disposed between the cassette holder (14) and the tape cassette holding portion (76). The cassette transport mechanism (U1) moves the tape cassette (5) between the cassette holder (14) and the tape cassette holding portion (76) via the intermediate portion (151). The second cassette transport mechanism (U20) moves the intermediate portion (151) together with the cassette transport head (37) in the second direction (D2).

[0182] According to the above configuration, the tape cassette (5) placed in the relay section (151) can be aligned with respect to the feeder (8) in the second direction (D2).

[0183] In addition, in the carrier tape supply device (Y1) according to a fifth aspect, in any one of the first to fourth aspects, the carrier tape transfer mechanism (TT1) has a leading end transfer head (V1) and a leading end transport mechanism (W1). The leading end transfer head (V1) captures the leading end (61) of the carrier tape (6). The leading end transport mechanism (W1) moves the leading end transfer head (V1) to move the leading end (61) of the carrier tape (6) to the standby tape holding section (81).

[0184] According to the above configuration, the leading end (61) of the carrier tape (6) can be moved.

[0185] In addition, in the carrier tape supply device (Y1) according to the sixth aspect, in the fifth aspect, the leading edge transport mechanism (W1) includes a first leading edge transport mechanism (W10) and a second leading edge transport mechanism (W20). The first leading edge transport mechanism (W10) moves the leading edge transport head (V1) in a first direction (D1). The first direction (D1) is the direction in which the cassette holder (14) and the tape cassette holding section (76) are aligned. The second leading edge transport mechanism (W20) moves the leading edge transport head (V1) in a second direction (D2). The second direction (D2) is a direction that intersects with the first direction (D1) and is along a horizontal plane.

[0186] According to the above configuration, the tip portion (61) can be moved in two directions, that is, the first direction (D1) and the second direction (D2).

[0187] In addition, in the carrier tape supply device (Y1) according to a seventh aspect, in the fifth or sixth aspect, the leading end transport head (V1) includes a payout mechanism (42). The payout mechanism (42) pays out the leading end (61) of the carrier tape (6) to the standby tape holding section (81).

[0188] According to the above configuration, the tip portion (61) can be moved relative to the tip transport head (V1).

[0189] In addition, in the carrier tape supply device (Y1) according to an eighth aspect, in any one of the fifth to seventh aspects, the holding structure (52) has a holding portion (520). The holding portion (520) holds the leading end (61) of the carrier tape (6).
