Description

Roll body manufacturing apparatus and roll body manufacturing method

The present invention relates to a roll body manufacturing device and a roll body manufacturing method.

　Conventionally, a tape feeder is known as a component supply unit in a component mounting device that mounts components on a board, which supplies components to a component removal position by transporting a carrier tape containing components. The carrier tape used in the tape feeder is wound around a reel that serves as the carrier tape holder, and when winding the carrier tape, for example, the carrier tape is wound using a carrier tape processing device (roll body manufacturing device) as shown in Patent Document 1.

JP 2021-153153 A

However, the winding process can place excessive stress on the carrier tape, which can cause the strength of the carrier tape to decrease.

The object of the present invention is to provide a roll body manufacturing device that can reduce the load on the carrier tape.

(1) A roll body manufacturing apparatus according to one aspect of the present invention is a roll body manufacturing apparatus for manufacturing a roll body in which carrier tape is wound into a roll, and includes a pull-out section that pulls out the carrier tape from an original reel around which the carrier tape is wound to an end portion, a first motor that is a drive source for the pull-out section, and a rewinding section that rewinds the carrier tape pulled out from the original reel by the pull-out section from the end portion, the rewinding section including a take-up body to which the end portion of the carrier tape is attached, a rotating shaft to which the take-up body is connected, and a second motor that is a drive source for rotating the rotating shaft, and the first motor is in a free state when the rotating shaft is rotated by the second motor to rewind the carrier tape onto the take-up body.

　A roll body manufacturing method according to another aspect of the present invention is a roll body manufacturing method executed by a roll body manufacturing apparatus that manufactures a roll body in which carrier tape is wound into a roll, the roll body manufacturing apparatus comprising: a pull-out section that pulls out the carrier tape from an original reel on which the carrier tape is wound to an end portion, a first motor that is a drive source for the pull-out section, and a rewinding section that rewinds the carrier tape pulled out from the original reel by the pull-out section from the end portion, the rewinding section comprising a take-up body to which the end portion of the carrier tape is attached, a rotating shaft to which the take-up body is connected, and a second motor that is a drive source for rotating the rotating shaft, and the roll body manufacturing method includes rotating the rotating shaft by the second motor, and setting the first motor in a free state when the rotating shaft is rotated by the second motor to rewind the carrier tape onto the take-up body.

With these, the second motor rotates the rotating shaft, and the first motor is in a free state when the carrier tape is rewound onto the winding body. Therefore, torque from the first motor is unlikely to be applied to the carrier tape during rewinding. Therefore, the load on the carrier tape can be reduced.

(2) The roll body manufacturing device described in (1) above may have a clutch unit that switches the first motor between a power transmission state and a free state.

In this way, the clutch section switches between the power transmission state of the first motor and the free state, so this switching can be performed smoothly. The smoother the switching, the smoother the load on the carrier tape can be reduced.

(3) In the roll body manufacturing apparatus described in (1) or (2) above, the pull-out section may have a limiting section that limits the widthwise position of the carrier tape.

As a result, the limiting portion limits the widthwise position of the carrier tape, so the carrier tape can be rewound while minimizing positional deviation in the widthwise direction, thereby minimizing winding deviation.

(4) In the roll body manufacturing apparatus described in (3) above, the limiting portion may be a rod-shaped body.

As a result, because the limiting portion is a rod-shaped body, the space consumed by the limiting portion can be reduced. This makes it possible to prevent the roll body manufacturing device itself from becoming too large.

(5) In the roll body manufacturing apparatus described in any one of (1) to (4) above, the pull-out section and the rewinding section may be arranged along a horizontal plane.

For example, if the pull-out section and rewinding section are arranged along the vertical direction, the carrier tape may sag under its own weight when rewinding stops, which may increase the load on the carrier tape. In this embodiment, the pull-out section and rewinding section are arranged along a horizontal plane, so the carrier tape also moves horizontally and is less likely to sag. In other words, the load on the carrier tape can be reduced.

(6) In the roll body manufacturing apparatus described in any one of (1) to (5) above, a storage section is provided that stores the roll body of the carrier tape rewound by the rewinding section in a container, and the pull-out section, the rewinding section, and the storage section may be arranged along a horizontal plane.

With this, the pull-out section, rewind section, and storage section are arranged along a horizontal plane, so the carrier tape also moves horizontally and is less likely to sag. In other words, the load on the carrier tape can be reduced.

(7) In the roll body manufacturing apparatus described in (6) above, a control unit that controls the second motor is provided, and the pull-out unit includes a reading unit that reads information about the carrier tape from an ID tag attached to the master reel and notifies a host system of the information, and the control unit may obtain information corresponding to the roll body stored in the container from the host system and control the second motor based on the information.

In this way, the control unit obtains information corresponding to the roll body stored in the container from a higher-level system, and controls the second motor based on that information. This allows the roll body to be formed under conditions suitable for the carrier tape.

(8) In the roll body manufacturing apparatus described in any one of (1) to (7) above, the winding body may be freely switched between a first form in which the carrier tape is wound and a second form that is smaller than the first form.

As a result, the winding body can be freely switched between the first and second configurations, so that after the roll body is completed, the winding body can be smoothly removed from the roll body by switching it to the second configuration.

(9) In the roll body manufacturing device described in (8) above, the winding body may have a clamping portion that clamps the end portion of the carrier tape, and the first form and the second form may be switched in conjunction with the operation of the clamping portion.

As a result, the clamp section can be operated to switch between the first and second configurations, making it possible to perform these operations all at once. This can improve work efficiency.

A roll body manufacturing apparatus according to another aspect of the present invention is a roll body manufacturing apparatus that manufactures a roll body in which carrier tape is wound into a roll, and includes a pull-out section that pulls out the carrier tape from an original reel on which the carrier tape is wound to an end portion, a first motor that is a drive source for the pull-out section, and a rewinding section that rewinds the carrier tape pulled out from the original reel by the pull-out section from the end portion, and the pull-out section and the rewinding section are arranged along a horizontal plane.

With this, the pull-out section and the rewind section are arranged along a horizontal plane, so the carrier tape also moves horizontally and is less likely to sag. In other words, the load on the carrier tape can be reduced.

The present invention reduces the load on the carrier tape.

Below, the roll body manufacturing apparatus and the like according to the embodiment of the present invention will be described with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, the arrangement and connection of the components, steps, and the order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, each figure is a schematic diagram, and the dimensions are not necessarily illustrated precisely. Furthermore, in each figure, the same or similar components are given the same reference numerals. In the following description, the X-axis direction is the width direction of the roll body manufacturing apparatus 10, the Y-axis direction is the arrangement direction of each part (the original reel support part 20, the pull-out part 30, the rewinding part 40, and the storage part 50) of the roll body manufacturing apparatus 10, and the Z-axis direction is the height direction (vertical direction) of the roll body manufacturing apparatus 10.

Furthermore, expressions indicating relative directions or attitudes, such as parallel and perpendicular, also include cases where the direction or attitude is not strictly that. For example, saying that two directions are parallel does not only mean that the two directions are completely parallel, but also means that the directions are substantially parallel, that is, that there is a difference of, for example, about a few percent. Furthermore, simply saying "X-axis direction" means both directions parallel to the X-axis, or either one of the directions. The same applies to terms related to the Y-axis and Z-axis.

(Embodiment)
Fig. 1 and Fig. 2 are perspective views showing a roll body manufacturing apparatus 10 according to an embodiment. Fig. 3 is a top view showing the roll body manufacturing apparatus 10 according to an embodiment. Fig. 4 is a front view showing the roll body manufacturing apparatus 10 according to an embodiment. Fig. 1 shows a state in which the lid portions (first lid portion 22, second lid portion 32, third lid portion 42) of the roll body manufacturing apparatus 10 are closed, and Figs. 2 and 3 show a state in which the lid portions are open. In Fig. 4, the lid portions are not shown.

As shown in Figures 1 to 4, the roll body manufacturing apparatus 10 includes an original reel support section 20, a pull-out section 30, a rewinding section 40, and a storage section 50, which are arranged in this order from the negative Y-axis direction to the positive Y-axis direction. Specifically, the roll body manufacturing apparatus 10 has a rectangular parallelepiped device main body 11, on whose upper portion the original reel support section 20, the pull-out section 30, and the rewinding section 40 are arranged. At the end of the device main body 11 in the positive Y-axis direction, a storage section 50 is provided that protrudes from the device main body 11 in the positive Y-axis direction.

The roll body manufacturing apparatus 10 pulls out the carrier tape 55 (see FIG. 26) from the original reel 56 supported by the original reel support section 20 at the pull-out section 30 and winds it up once. After that, in the roll body manufacturing apparatus 10, the rewinding section 40 rewinds the carrier tape 55 from the pull-out section 30 to produce a roll body 57, and the roll body 57 is stored in the storage container 70 at the storage section 50.

Here, carrier tape 55 is a tape that houses multiple components at a predetermined interval. Carrier tape 55 includes a tape body and a cover tape attached to the tape body. The tape body has multiple component pockets arranged at a predetermined interval in the longitudinal direction of the tape body. A component is stored in each component pocket. The cover tape is attached to the tape body to cover each component pocket. Carrier tape 55 is wound around master reel 56. When carrier tape 55 is wound around master reel 56, the end of carrier tape 55 on the center side is referred to as terminal end 551, and the end of carrier tape 55 on the outermost peripheral side is referred to as tip end 552.

Furthermore, the master reel 56 is provided with an ID tag 550 (see FIG. 3) that stores information about the carrier tape 55. The information about the carrier tape 55 includes, for example, the part numbers of the parts stored on the carrier tape 55, the total number of parts, the width of the carrier tape 55, etc.

The master reel support section 20 is a section that supports the master reel 56. Specifically, the master reel support section 20 has a first support section 21, a first cover section 22, and a reading section 23. The first support section 21 is a section that supports the master reel 56, and has a first installation surface 211 on which the master reel 56 is installed, a rotating shaft 212 that supports the master reel 56, and an idler 213. The first installation surface 211 is disposed along a horizontal plane (XY plane). The rotating shaft 212 is disposed in the center of the first installation surface 211 when viewed from above, and protrudes upward. When the master reel 56 is attached to the rotating shaft 212, the master reel 56 becomes freely rotatable around the rotating shaft 212. The idler 213 is disposed at the corners of the first installation surface 211 in the negative X-axis direction and the positive Y-axis direction.

The first lid portion 22 is a portion that covers the upper part of the first support portion 21. The first lid portion 22 is a rectangular box body that is open in the positive Y-axis direction and the negative Z-axis direction. The first lid portion 22 is rotatably connected to the end of the first support portion 21 in the negative X-axis direction.

The reading unit 23 is an ID tag reader that reads information about the carrier tape 55 from the ID tag 550 attached to the original reel 56 and notifies the host system 100 (see FIG. 15) via the control unit 15. The reading unit 23 is a handy type, and is detachably installed on the first installation surface 211. When an operator holds the reading unit 23 and brings it close to the ID tag 550 on the original reel 56, the information in the ID tag 550 is read by the reading unit 23.

The pull-out section 30 is a section where the carrier tape 55 is pulled out from the original reel 56 to the terminal end 551 and temporarily wound around it. Specifically, the pull-out section 30 has a second support section 31, a second cover section 32, and a pair of limiting sections 33.

The second support portion 31 is a portion that supports the carrier tape 55 to be temporarily wound, and has a second installation surface 311 on which the carrier tape 55 is installed, a first shaft portion 61 that is the winding center of the carrier tape 55, and an idler 313. The second installation surface 311 is arranged along a horizontal plane (XY plane). The first shaft portion 61 is formed in a cylindrical shape and has a clamp portion that clamps the tip portion 552 of the carrier tape 55. The first shaft portion 61 is arranged in the center of the second installation surface 311 when viewed from above, and protrudes upward. The first shaft portion 61 is connected to a rotating shaft 312 provided on the second installation surface 311. By rotating the first shaft portion 61, the carrier tape 55 is wound around the first shaft portion 61 with the tip portion 552 as the center. At this time, the terminal end portion 551 of the carrier tape 55 is arranged on the outermost circumference. The idler 313 is disposed at the corners of the second installation surface 311 in the positive X-axis direction and the positive Y-axis direction.

The second lid portion 32 is a portion that covers the upper part of the second support portion 31. The second lid portion 32 is a rectangular box body that is open in the positive Y-axis direction, the negative Y-axis direction, and the negative Z-axis direction. The second lid portion 32 is rotatably connected to the end of the second support portion 31 in the negative X-axis direction.

The pair of limiting portions 33 are portions that limit the position of the carrier tape 55 in the width direction (Z-axis direction) while it is being wound by the pull-out portion 30. The base end of one limiting portion 33 is disposed at a corner of the second installation surface 311 in the negative X-axis direction and the positive Y-axis direction. The base end of the other limiting portion 33 is disposed at the center of the second installation surface 311 in the positive X-axis direction and the positive Y-axis direction. Details of the limiting portions 33 will be described later.

The rewinding section 40 is a section that rewinds the carrier tape 55 from the terminal end 551 that has been pulled out from the original reel 56 by the pull-out section 30 and temporarily wound around it. Specifically, the rewinding section 40 has a third support section 41, a third cover section 42, and a pair of limiting sections 43.

The third support portion 41 is a portion that supports the carrier tape 55 to be rewound, and has a third installation surface 411 on which the carrier tape 55 is installed, and a second shaft portion 62 that is the winding center of the carrier tape 55. The third installation surface 411 is arranged along a horizontal plane (XY plane). The second shaft portion 62 is an example of a winding body to which the end portion 551 of the carrier tape 55 is attached. The second shaft portion 62 is arranged in the center of the third installation surface 411 when viewed from above, and protrudes upward. The second shaft portion 62 is detachable from the rotating shaft 412 provided on the third installation surface 411. By rotating the second shaft portion 62, the carrier tape 55 is wound around the second shaft portion 62 with the end portion 551 as the center, and becomes a roll body 57. At this time, the tip portion 552 of the carrier tape 55 is arranged on the outermost circumference of the roll body 57. The second shaft portion 62 will be described in detail later.

The third lid portion 42 is a portion that covers the upper part of the third support portion 41. The third lid portion 42 is a rectangular box body that is open in the negative Y-axis direction and the negative Z-axis direction. The third lid portion 42 is rotatably connected to the end of the third support portion 41 in the negative X-axis direction.

The pair of limiting sections 43 are sections that limit the position of the carrier tape 55 in the width direction (Z axis direction) while it is being rewound by the rewinding section 40. The base end of one limiting section 43 is located at a corner of the third installation surface 411 in the negative X-axis direction and negative Y-axis direction. The base end of the other limiting section 43 is located at a corner of the third installation surface 411 in the positive X-axis direction and negative Y-axis direction. Details of the limiting sections 43 will be described later.

In the device body 11, a first shutter 112 that can appear and disappear in the Z-axis direction is provided between the first installation surface 211 and the second installation surface 311. The first shutter 112 is a wall parallel to the XZ plane and is movable in the Z-axis direction. In the device body 11, a second shutter 113 that can appear and disappear in the Z-axis direction is provided between the second installation surface 311 and the third installation surface 411. The second shutter 113 is a wall parallel to the XZ plane and is movable in the Z-axis direction. Note that FIG. 2 shows a state in which the first shutter 112 is buried and the second shutter 113 is emerged. The first shutter 112 and the second shutter 113 may be manual or automatic.

The storage section 50 is a section that stores the roll body 57 formed in the rewinding section 40 in the storage container 70. The storage section 50 has a storage container support section 51 that supports the storage container 70. The storage container support section 51 has an installation surface 511 on which the storage container 70 is installed. The installation surface 511 is arranged along a horizontal plane (XY plane) so as to be flush with the third installation surface 411. Here, the storage container 70 is a flat rectangular box body that is open in the negative Y-axis direction. Therefore, the roll body 57 can be slid from the third installation surface 411 to the installation surface 511 and smoothly stored in the storage container 70 from the open portion of the storage container 70.

Next, the restricting portion 43 will be described. Note that the pair of restricting portions 33 and the pair of restricting portions 43 have the same basic configuration, so here, the specific structure of only one restricting portion 43 will be described, and a description of the other restricting portions will be omitted.

FIG. 5 is a perspective view showing the limiting portion 43 according to the embodiment. Specifically, FIG. 5 illustrates one of the limiting portions 43 of the rewinding portion 40. As shown in FIG. 5, the limiting portion 43 is a rod-shaped body extending along the XY plane. The limiting portion 43 in FIG. 5 is cylindrical, but may be prismatic. The base of the limiting portion 43 is supported by a support 431 protruding in the positive direction of the Z axis from the third installation surface 411. The limiting portion 43 may rotate along the XY plane around the support 431. The limiting portion 43 contacts the carrier tape 55 wound below it, suppressing misalignment of the carrier tape 55 in the Z axis direction. The support position of the limiting portion 43 relative to the support 431 is adjustable. In other words, since the position of the limiting portion 43 in the Z axis direction can be adjusted, the position of the limiting portion 43 can be adjusted to a position according to the width of each of the different types of carrier tapes 55.

Next, we will explain the second shaft portion 62.

FIG. 6 is a perspective view showing the second shaft portion 62 according to the embodiment in an unclamped state. FIG. 7 is a perspective view showing the second shaft portion 62 according to the embodiment in a clamped state. FIG. 8 is a perspective view showing the second shaft portion 62 according to the embodiment in an expanded state. Note that the carrier tape 55 is omitted from FIGS. 7 and 8.

The unclamped state is the state before the carrier tape 55 is clamped. The clamped state is the state in which the carrier tape 55 is clamped. The expanded state is a state in which the outer shape is larger than the unclamped state and the clamped state. In other words, the expanded state is the first form according to the present invention, and the unclamped state and the clamped state are the second form according to the present invention.

As shown in Figures 6 to 8, the second shaft portion 62 has a main body portion 63, multiple outer peripheral walls 64, and a clamp portion 65. The main body portion 63 is a shaft extending in the Z-axis direction, and its lower portion is detachably connected to the rotating shaft 312 (or rotating shaft 412) provided on the second installation surface 311 (or third installation surface 411). The multiple outer peripheral walls 64 are walls formed in an arc shape when viewed in the Z-axis direction, and are arranged at intervals in the circumferential direction. The multiple outer peripheral walls 64 form the outer peripheral surface of the second shaft portion 62, and the carrier tape 55 is wound around the outer peripheral surfaces of the multiple outer peripheral walls 64. A roller 641 is provided on the upper portion of the multiple outer peripheral walls 64.

The multiple outer peripheral walls 64 expand outward and contract inward in response to the operation of the clamping portion 65. To achieve this operation, a link mechanism (not shown) is provided between each outer peripheral wall 64 and the main body portion 63 to connect them. The link mechanism biases the multiple outer peripheral walls 64 inward.

The clamp unit 65 has a rotation operation unit 651, a first clamping unit 652, and a second clamping unit 653. The rotation operation unit 651 is rotatably provided on the upper part of the main body unit 63. A pair of gripping units 654 is provided on the upper part of the rotation operation unit 651. When an operator grips and rotates the pair of gripping units 654, the rotation operation unit 651 itself rotates. A number of protrusions 655 corresponding to the rollers 641 of each outer wall 64 are provided on the outer circumferential surface of the rotation operation unit 651. Each protrusion 655 moves toward or away from each roller 641 as the rotation operation unit 651 rotates.

The first clamping portion 652 and the second clamping portion 653 are portions that clamp the carrier tape 55. The first clamping portion 652 and the second clamping portion 653 are disposed between a pair of adjacent outer peripheral walls 64. The first clamping portion 652 is fixed to the main body portion 63, but the second clamping portion 653 moves closer to and away from the first clamping portion 652 as the rotation operation portion 651 rotates. By disposing the carrier tape 55 between the first clamping portion 652 and the second clamping portion 653 and bringing the second clamping portion 653 closer to the first clamping portion 652, the first clamping portion 652 and the second clamping portion 653 clamp the carrier tape 55.

The operation of the second shaft portion 62 will be described in detail. The second shaft portion 62, which does not hold the carrier tape 55, is in an unclamped state as shown in FIG. 6. After that, when the operator holds the pair of gripping portions 654 and rotates the rotation operation portion 651 clockwise, each protrusion 655 comes into contact with each roller 641 as shown in FIG. 7. At this time, the first clamping portion 652 and the second clamping portion 653 are closest to each other. In this state, the carrier tape 55 can be clamped. Furthermore, when the rotation operation portion 651 is rotated clockwise, each roller 641 moves outward along each protrusion 655. As a result, each outer peripheral wall 64 spreads outward and enters an expanded state as shown in FIG. 8. In this expanded state, the carrier tape 55 is wound around the second shaft portion 62.

When winding is complete, the worker grasps the pair of gripping portions 654 and rotates the rotation operation portion 651 counterclockwise, causing each protrusion 655 to release the pressure on each roller 641 as shown in FIG. 7. This causes each outer peripheral wall 64 to shrink inward. When the rotation operation portion 651 is further rotated counterclockwise, the second clamping portion 653 separates from the first clamping portion 652, releasing the clamping of the carrier tape 55. This makes it possible to smoothly remove the second shaft portion 62 from the carrier tape 55 after winding.

The winding body is not limited to the configuration described above. Here, we will explain modified examples of the winding body.

First, the winding body 80 according to the modified example 1 will be described. Fig. 9 is a perspective view showing the second form of the winding body 80 according to the modified example 1. Fig. 10 is a cross-sectional view showing the second form of the winding body 80 according to the modified example 1. Fig. 11 is a perspective view showing the first form of the winding body 80 according to the modified example 1. Fig. 12 is a cross-sectional view showing the first form of the winding body 80 according to the modified example 1.

As shown in Figures 9 to 12, the winding body 80 has a main body 83, multiple outer peripheral walls 84, and a clamp portion 85. The main body 83 is a shaft extending in the Z-axis direction, and its lower portion is detachably connected to the rotating shaft 312 (or rotating shaft 412) provided on the second installation surface 311 (or the third installation surface 411). The multiple outer peripheral walls 84 are walls whose outer peripheral surfaces are formed in an arc shape when viewed in the Z-axis direction, and are arranged at intervals in the circumferential direction. The multiple outer peripheral walls 84 form the outer peripheral surface of the winding body 80, and the carrier tape 55 is wound around the outer peripheral surfaces of the multiple outer peripheral walls 84.

The multiple outer walls 84 expand outward and contract inward in conjunction with the operation of the clamping portion 85. To achieve this operation, rollers 841 are attached to the inner surface of each outer wall 84.

The clamp unit 85 has a rotation operation unit 851, a first clamping unit 852, a second clamping unit 853, and a cam member 855. The rotation operation unit 851 is connected to the upper part of the main body unit 83. A gripping unit 854 is provided on the upper part of the rotation operation unit 851. A plurality of recesses 856 are formed on the outer periphery of the rotation operation unit 851. When an operator grips the gripping unit 854 or hooks their fingers into the plurality of recesses 856 to rotate the rotation operation unit 851 and the main body unit 83, the rotation operation unit 851 and the main body unit 83 rotate relative to the plurality of outer periphery walls 84.

The cam member 855 is connected to the main body 83 below the rotation operation part 851. The outer peripheral edge of the cam member 855 has multiple recesses and multiple protrusions formed such that the recesses and protrusions are repeated in the circumferential direction. The rollers 841 of each outer peripheral wall 84 contact the outer peripheral edge of the cam member 855. When the rotation operation part 851 and the main body 83 rotate, the cam member 855 also rotates, pushing the rollers 841 of each outer peripheral wall 84 outward and releasing the pushing force.

The first clamping portion 852 and the second clamping portion 853 are portions that clamp the carrier tape 55. The first clamping portion 852 and the second clamping portion 853 are disposed between a pair of adjacent outer peripheral walls 64. The first clamping portion 852 is fixed in a predetermined position, while the second clamping portion 853 is connected to the main body portion 83 and moves toward and away from the first clamping portion 852 as the main body portion 83 rotates. By disposing the carrier tape 55 between the first clamping portion 852 and the second clamping portion 853 and bringing the second clamping portion 853 closer to the first clamping portion 852, the first clamping portion 852 and the second clamping portion 853 clamp the carrier tape 55.

The operation of the winding body 80 will be specifically described. The winding body 80, which does not hold the carrier tape 55, is in the second form (unclamped state) as shown in Figures 9 and 10. After that, when the operator rotates the rotation operation part 851 clockwise, the main body part 83 also rotates, and as shown in Figures 11 and 12, the first clamping part 852 and the second clamping part 853 are closest to each other. In this state, the carrier tape 55 can be clamped. During this rotation, the cam member 855 also rotates in conjunction with the rotation of the main body part 83, pushing the rollers 841 of each outer peripheral wall 84 outward. As a result, each outer peripheral wall 84 also expands outward, and the winding body 80 is in the first form (expanded body). In this first form, the carrier tape 55 is wound around the winding body 80.

When winding is complete, the worker rotates the rotary operation unit 851 counterclockwise, which also rotates the main body 83 and cam member 855, releasing the pressing force of each outer peripheral wall 84 against the roller 841, as shown in Figures 9 and 10. This causes the worker to shrink each outer peripheral wall 84 inward. At this time, the second clamping unit 853 separates from the first clamping unit 852, releasing the clamping of the carrier tape 55. This makes it possible to smoothly remove the take-up body 80 from the carrier tape 55 after winding.

Next, we will explain the winding body 90 according to the modified example 2. Figure 13 is a perspective view showing the second form of the winding body 90 according to the modified example 2. Figure 14 is a perspective view showing the first form of the winding body 90 according to the modified example 2.

13 and 14, the winding body 90 has a main body 93, a pair of outer peripheral walls 94a, 94b, and a clamp portion 95. The main body 93 is a shaft extending in the Z-axis direction, and its lower portion is detachably connected to the rotating shaft 312 (or the rotating shaft 412) provided on the second installation surface 311 (or the third installation surface 411). The pair of outer peripheral walls 94a, 94b are each a wall body formed in a semi-cylindrical shape, and the other outer peripheral wall 94b is disposed inside one outer peripheral wall 94a. The other outer peripheral wall 94b is slidable in the circumferential direction relative to the one outer peripheral wall 94a. When the pair of outer peripheral walls 94a, 94b become cylindrical and assume a first form, the carrier tape 55 is wound along the outer peripheral surfaces of the pair of outer peripheral walls 94a, 94b. When the other outer peripheral wall 94b fits within the one outer peripheral wall 94a, the second form is smaller than the first form.

The clamp portion 95 has a rotation operation portion 951, a first clamping portion 952, and a second clamping portion 953. The rotation operation portion 951 is provided on the upper portion of the main body portion 93. The rotation operation portion 951 includes a top plate portion 954 that covers the upper portion of the main body portion 93, and a rotor 955 that is disposed below the top plate portion 954. The top plate portion 954 is provided with a first gripping portion 956 and has an arc-shaped slit 957 formed therein.

The rotating body 955 has a second gripping portion 958 protruding from the slit 957. The rotating body 955 is connected to the other outer peripheral wall 94b. In other words, when an operator grips the first gripping portion 956 and the second gripping portion 958 and rotates the second gripping portion 958 along the slit 957, the rotating body 955 and the other outer peripheral wall 94b rotate in conjunction with the rotation.

The first clamping portion 952 and the second clamping portion 953 are portions that clamp the carrier tape 55. The first clamping portion 952 is provided at one end of one outer peripheral wall 94a. The second clamping portion 953 is provided at one end of the other outer peripheral wall 94b. As the other outer peripheral wall 94b rotates, the second clamping portion 953 moves closer to or away from the first clamping portion 952. By placing the carrier tape 55 between the first clamping portion 952 and the second clamping portion 953 and bringing the second clamping portion 953 closer to the first clamping portion 952, the first clamping portion 952 and the second clamping portion 953 clamp the carrier tape 55.

The operation of the winding body 90 will be described in detail. The winding body 90, which does not hold the carrier tape 55, is in the second form (unclamped state) as shown in FIG. 13. When the operator then rotates the rotating body 955 of the rotation operation unit 951 counterclockwise, the other outer peripheral wall 94b also rotates, and the first clamping portion 952 and the second clamping portion 953 are closest to each other as shown in FIG. 14. In this state, the carrier tape 55 can be clamped. Furthermore, because this state is the first form, the carrier tape 55 held by the first clamping portion 952 and the second clamping portion 953 can be wound onto the winding body 90.

When winding is complete, the operator rotates the rotating body 955 of the rotation operating unit 951 clockwise, which causes the other outer peripheral wall 94b to rotate as well, and the winding body 90 assumes the second form as shown in FIG. 13. At this time, the second clamping portion 953 separates from the first clamping portion 952, and clamping of the carrier tape 55 is also released. This makes it possible to smoothly remove the winding body 90 from the carrier tape 55 after winding.

Next, the control configuration of the roll body manufacturing apparatus 10 will be described. FIG. 15 is a block diagram showing the control configuration of the roll body manufacturing apparatus 10 according to the embodiment. As shown in FIG. 15, the roll body manufacturing apparatus 10 is connected to a higher-level system 100 consisting of a management computer via a communication network. In other words, the roll body manufacturing apparatus 10 is controlled by the higher-level system 100.

The roll body manufacturing device 10 has a reading unit 23, a first motor 38, a clutch unit 39, a second motor 48, a communication unit 12, and a control unit 13.

The first motor 38 is a drive source for rotating the rotating shaft 312 of the drawer section 30. The first motor 38 is disposed below the second installation surface 311 of the drawer section 30, and is connected to the rotating shaft 312 of the drawer section 30 via a power transmission mechanism (not shown). When the first shaft section 61 is connected to the rotating shaft 312 of the drawer section 30, the power of the first motor 38 is transmitted to the first shaft section 61 via the power transmission mechanism and the rotating shaft 312, causing the first shaft section 61 to rotate.

The clutch unit 39 switches between the power transmission state of the first motor 38 and a free state. Specifically, the clutch unit 39 is incorporated in a power transmission mechanism that connects the rotating shaft 312 of the drawer unit 30 and the first motor 38. The clutch unit 39 switches between the power transmission state and the free state by switching between connection and disconnection of mechanical elements in the power transmission mechanism. Any clutch unit 39 may be used as long as it can switch between the power transmission state and the free state. Examples of the clutch unit 39 include a mesh clutch, a friction clutch, a centrifugal clutch, and an electromagnetic friction clutch.

The second motor 48 is a drive source for rotating the rotating shaft 412 of the rewinding unit 40. The second motor 48 is disposed below the third installation surface 411 of the rewinding unit 40, and is connected to the rotating shaft 412 of the rewinding unit 40 via a power transmission mechanism (not shown). When the second shaft portion 62 is connected to the rotating shaft 412 of the rewinding unit 40, the power of the second motor 48 is transmitted to the second shaft portion 62 via the power transmission mechanism and the rotating shaft 412, causing the second shaft portion 62 to rotate.

The communication unit 12 is a communication module for communicating with the host system 100 wirelessly or via a wired connection, and is freely connected to a communication network. The control unit 13 has a CPU, RAM, and ROM, and the CPU expands a program in the ROM into the RAM and executes it to control each part of the roll body manufacturing apparatus 10. The control unit 13 may also control each part based on commands from the host system 100.

Next, the roll body manufacturing method executed by the roll body manufacturing apparatus 10 will be described. Figures 16 to 39 are explanatory diagrams showing each step of the roll body manufacturing method according to the embodiment. Figures 16 to 39 show schematic top views of the roll body manufacturing apparatus 10. Also, each lid portion (first lid portion 22, second lid portion 32, and third lid portion 42) is shown only in the closed state, and is not shown in the open state.

FIG. 16 shows the carrier tape 55 being rewound from the pull-out section 30 to the rewinding section 40. Specifically, the control section 13 drives the second motor 48 to rotate the rotating shaft 412 and the second shaft section 62, and wind the carrier tape 55 around the second shaft section 62. At this time, the control section 13 controls the clutch section 39 to put the first motor 38 in a free state. Therefore, torque from the first motor 38 is not easily applied to the carrier tape 55 during rewinding. This makes it possible to reduce the load on the carrier tape 55.

In the state shown in FIG. 16, the first lid 22 is open, while the second lid 32 and third lid 42 are closed. The first shutter 112 is exposed, and the second shutter 113 is recessed. This prevents foreign matter from entering the pull-out section 30 and the rewinding section 40. In the pull-out section 30, the limiting section 33 limits the position of the carrier tape 55 within the pull-out section 30, and in the rewinding section 40, the limiting section 43 limits the position of the carrier tape 55 within the rewinding section 40. In addition, the empty master reel 56 has been removed from the master reel support section 20, and an empty container 70 has been installed in the container section 50.

Next, as shown in FIG. 17, the worker sets the new master reel 56 on the master reel support portion 20.

Next, as shown in FIG. 18, the worker uses the reading unit 23 to read information about the carrier tape 55 from the ID tag 550 of the original reel 56. The information read by the reading unit 23 is output to the host system 100 via the communication unit 12. Based on the acquired information, the host system 100 creates appropriate conditions for winding the carrier tape 55 of the original reel 56 in the rewinding unit 40.

Next, as shown in FIG. 19, the worker pulls out the tip 552 of the carrier tape 55 from the master reel 56 set on the master reel support 20 and cuts it into the specified shape.

Next, as shown in FIG. 20, the worker temporarily sets the tip 552 of the carrier tape 55 on the idler 213.

Next, as shown in FIG. 21, when rewinding is completed and the roll body 57 is formed on the second shaft portion 62, the worker opens the second lid portion 32 and the third lid portion 42. At this time, the first shutter 112 is buried.

Next, as shown in FIG. 22, the worker removes the tip 552 of the carrier tape 55 from the first shaft portion 61 and temporarily sets it on the idler 313.

Next, as shown in FIG. 23, the worker clamps the tip 552 of the carrier tape 55 of the original reel 56 with the first shaft portion 61 via the idler 213.

Next, as shown in FIG. 24, the worker adjusts the position of one of the limiting portions 33 of the pull-out section 30 so that it corresponds to the carrier tape 55 clamped by the first shaft portion 61.

Next, as shown in FIG. 25, the operator closes the first lid portion 22 and the second lid portion 32 while leaving the third lid portion 42 open. At this time, the first shutter 112 is recessed and the second shutter 113 is exposed. This prevents foreign objects from entering the original reel support portion 20 and the pull-out portion 30.

Next, as shown in FIG. 26, the control unit 13 controls the clutch unit 39 to put the first motor 38 into a power transmission state, and then drives the first motor 38 to rotate the rotating shaft 312 and the first shaft portion 61, thereby winding the carrier tape 55 around the first shaft portion 61.

Next, as shown in FIG. 27, when winding the first shaft portion 61, the worker cuts the tip portion 552 of the roll body 57 formed on the second shaft portion 62 into the specified shape.

Next, as shown in Figure 28, the worker adjusts the excess length of the roll body 57.

Next, as shown in FIG. 29, the worker places the second shaft portion 62 in an unclamped state (second configuration) and removes the second shaft portion 62 from the roll body 57 while removing the terminal end 551 of the roll body 57 from the second shaft portion 62.

Next, as shown in FIG. 30, the worker slides the roll body 57 in the positive direction of the Y axis to accommodate the roll body 57 in the container 70 on the storage section 50.

Next, as shown in FIG. 31, the operator sets the tip 552 of the roll body 57 in a predetermined position in the container 70.

Next, as shown in FIG. 32, the operator attaches the second shaft portion 62 to the rotating shaft 412 of the rewinding section 40.

Next, as shown in FIG. 33, the worker removes the container 70 containing the roll body 57 from the storage section 50.

Next, as shown in FIG. 34, since the winding of the carrier tape 55 around the first shaft portion 61 is complete, the worker opens the first lid portion 22 and the second lid portion 32 while leaving the third lid portion 42 open. At this time, the first shutter 112 and the second shutter 113 are submerged.

Next, as shown in FIG. 35, the worker cuts the end portion 551 of the carrier tape 55 wound around the first shaft portion 61 and removes it from the original reel 56.

Next, as shown in FIG. 36, the worker clamps the end portion 551 of the carrier tape 55 wound around the first shaft portion 61 with the second shaft portion 62 via the idler 313.

Next, as shown in FIG. 37, the operator adjusts the position of one of the limiting portions 43 of the rewinding section 40 so that it corresponds to the carrier tape 55 clamped by the second shaft portion 62.

Next, as shown in FIG. 38, the operator closes the second cover 32 and the third cover 42 while leaving the first cover 22 open. At this time, the first shutter 112 appears, and the second shutter 113 is recessed. This prevents foreign matter from entering the pull-out section 30 and the rewind section 40. The control section 13 controls the clutch section 39 to set the first motor 38 in a free state, and then drives the second motor 48 to rotate the rotating shaft 412 and the second shaft section 62, thereby winding the carrier tape 55 around the second shaft section 62. At this time, the control section 13 has acquired the appropriate conditions created by the upper system 100, and controls the second motor 48 based on these conditions. This allows the carrier tape 55 to be appropriately wound around the second shaft section 62.

Next, as shown in FIG. 39, the worker sets an empty container 70 on the storage section 50. In this manner, the steps in FIG. 16 to FIG. 39 are repeated, and the roll body 57 is repeatedly stored in the container 70.

[effect]
As described above, when the rotary shaft 412 is rotated by the second motor 48 and the carrier tape 55 is rewound onto the second shaft portion 62 (the winding body), the first motor 38 is in a free state. Therefore, during rewinding, torque is not easily applied from the first motor 38 to the carrier tape 55. Therefore, the load on the carrier tape 55 can be suppressed.

The clutch section 39 switches the first motor 38 between a power transmission state and a free state, so this switching can be performed smoothly. The smoother the switching, the smoother the load on the carrier tape 55 can be reduced.

The limiting section 43 limits the widthwise position of the carrier tape 55, so the carrier tape 55 can be rewound while suppressing misalignment in the widthwise direction, thereby suppressing misalignment. This is also true for the limiting section 33.

Because the limiting portion 43 is a rod-shaped body, the space consumed by the limiting portion 43 can be reduced. Therefore, the size of the roll body manufacturing apparatus 10 itself can be reduced. This is also true for the limiting portion 33.

For example, if the pull-out section 30 and the rewinding section 40 are arranged along the vertical direction, the carrier tape 55 may sag under its own weight when rewinding stops, which may increase the load on the carrier tape 55. In this embodiment, the pull-out section 30 and the rewinding section 40 are arranged along a horizontal plane, so the carrier tape 55 also moves horizontally and is less likely to sag. In other words, the load on the carrier tape 55 can be reduced.

The control unit 13 obtains information corresponding to the roll body 57 stored in the container 70 from the host system 100, and controls the second motor 48 based on the information. This allows the roll body 57 to be formed under conditions suitable for the carrier tape 55.

Since the second shaft portion 62 (winding body) can be freely switched between the first and second configurations, after the roll body 57 is completed, the second shaft portion 62 can be smoothly removed from the roll body 57 by switching the second shaft portion 62 to the second configuration.

By operating the clamp section 65, the winding body (second shaft section 62) can be switched between the first and second configurations, so these operations can be performed all at once. This improves work efficiency.

(others)
The roll body manufacturing apparatus 10 and the roll body manufacturing method according to the embodiment of the present invention have been described above, but the present invention is not limited to this embodiment. In other words, the embodiment disclosed here is an example in all respects, and the scope of the present invention includes all modifications that are equivalent to the meaning and scope of the claims. Forms constructed by arbitrarily combining the components included in each of the above embodiments and their modified examples are also included in the scope of the present invention.

For example, in the above embodiment, the clutch unit 39 that switches between the power transmission state of the first motor 38 and a free state has been described, but another clutch unit that switches between the power transmission state of the second motor 48 and a free state may be provided. In this case, when the carrier tape 55 is wound from the rewinding unit 40 onto the pull-out unit 30, the second motor 48 can be put into a free state by the other clutch unit. During this winding, torque from the second motor 48 is unlikely to be applied to the carrier tape 55. Therefore, the load on the carrier tape 55 can be suppressed.

The present invention can be applied to roll body manufacturing equipment that manufactures roll bodies made of carrier tape.
