Description

The present invention relates to a component mounter that replaces a reel holding device.

Equipment for producing boards on which many components are mounted includes solder printing machines, component mounting machines, reflow machines, and board inspection machines. It is common to link these machines together to form a board production line. Of these, the component mounting machine includes a board transport device, a component supply device, a component transfer device, and a control device. A representative example of a component supply device is a feeder device that pays out a component storage tape in which components are stored in multiple component storage sections. In combination with this feeder device, a reel holding device is used that rotatably and replaceably holds a component supply reel around which the component storage tape is wound. Examples of technology related to this type of reel holding device are disclosed in Patent Documents 1 and 2.

The tape reel support device for electronic component supply cassettes in Patent Document 1 includes a frame body with an approximately U-shaped cross section that is open at the top, and a support arm that rotates around a pivot point located at the other end of the frame body and supports the center of the tape reel at the rotating end. With this, even when multiple electronic component supply cassettes (feeder devices) are mounted in parallel on the component mounter, the tape reel can be replaced at the other end of the frame body, eliminating the hassle of having to reach out from a distance.

Patent Document 2 also discloses a batch exchange cart that holds a large number of feeder devices in a row and is configured to be detachable from the main body of a component mounter. This batch exchange cart is equipped with a reel holding section that holds a reel so that the tape can be fed out, and a reel stock section that holds a spare reel to be used when the tape is consumed. According to this, when the tape held in the reel holding section is consumed, the spare reel from the reel stock section can be simply attached to the reel holding section, which is said to improve the operability of reel replacement.

JP 2004-228192 A JP 2004-228207 A

When changing the type of board (board type) produced by a component mounter, a changeover is required to change the type of components (component type) to be supplied. With the tape reel support device disclosed in Patent Document 1, there is no need to remove the feeder device from the component mounter during changeover work; only the reels need to be replaced (in-machine changeover). However, with this in-machine changeover method, the reels must be replaced for each component type to be changed, which lengthens the changeover time and prevents the production of boards during the changeover time. In other words, both work efficiency and production efficiency decrease.

On the other hand, with the batch exchange cart disclosed in Patent Document 2, reels corresponding to the component type required for the next type of board to be produced can be held in advance in the reel holding section of the replacement feeder device (external setup change). When changing the type of board to be produced, multiple feeder devices can be replaced at once using the batch exchange cart, improving work efficiency and production efficiency. However, with this method of external setup change, a large number of feeder devices are required to perform the batch replacement, which increases equipment costs.

The present invention was made in consideration of the problems in the background art described above, and aims to provide a component mounter that can achieve both high work efficiency and production efficiency during changeover work to change the type of components supplied, and reduced equipment costs.

The component mounting machine of the present invention, which solves the above problems, comprises an automatic feeder device that automatically pays out a component storage tape inserted into a tape insertion port to supply components, a reel holding device that rotatably and replaceably holds a component supply reel around which the component storage tape is wound, a feeder mounting section that detachably holds the automatic feeder device and a reel mounting section that detachably holds the reel holding device, and the feeder mounting section and reel mounting section are detachably mounted on a base.
The reel mounting section has a front mounting seat and a rear mounting seat, and a reel holding device that is detachably held by a self-propelled and transportable reel exchange device can be mounted on the upper side of the rear mounting seat.

According to the component mounter of the present invention, reels corresponding to multiple component types required for the next type of board to be produced can be held in advance in a replacement reel holding device. As a result, it is only necessary to replace a smaller number of reel holding devices than the number of reels during a changeover operation, and changeover time can be shortened compared to conventional techniques in which multiple individual reels are replaced. The number of feeder devices required during changeover can be reduced compared to conventional techniques in which multiple feeder devices are replaced all at once. Therefore, it is possible to achieve both high work efficiency and production efficiency during changeover operations and reduced equipment costs.

FIG. 2 is a side view of the reel changing device according to the embodiment.

(1. Overall configuration of parts supply unit)
A reel holding device 1 according to a first embodiment of the present invention will be described with reference to Figs. 1, 2, 5, and 6. The reel holding device 1 is mounted on a machine base 19, which is a part of a component mounter, together with an automatic feeder device 9, which is a feeder device, and plays a role in supplying components. Fig. 1 is a side view showing the overall configuration of a component supply unit in which the reel holding device 1 according to the first embodiment is combined with the automatic feeder device 9 and mounted on a common pallet 5. In Fig. 1, the front side (right side of the paper) of the automatic feeder device 9 is disposed in close proximity to a component mounting head (not shown) of the component mounter. In addition, the reel holding device 1 is disposed on the rear lower side of the automatic feeder device 9. Fig. 2 is a view of the reel holding device 1 according to the first embodiment as seen from the rear. The component mounter is a device for mounting components on a board, and includes the reel holding device 1, the common pallet 5, and the automatic feeder device 9.

The common pallet 5 is detachably mounted on the machine base 19 of the component mounting machine. The common pallet 5 is not limited to this, and may be fixedly mounted on the machine base 19. The common pallet 5 has a feeder mounting section 51 and a reel mounting section 55, and detachably holds the automatic feeder device 9 and the reel holding device 1. The feeder mounting section 51 is formed with an upright section 53 provided on the front side of a substantially rectangular flat section 52, and is substantially L-shaped in side view. The flat section 52 is engraved with slots 54 extending in the front-rear direction and aligned in the width direction. A plurality of automatic feeder devices 9 that are thin in the width direction are each mounted in the slot 54 and aligned in the width direction. In the first embodiment, 20 slots 54 are provided, and 20 automatic feeder devices 9 are aligned in a row.

The automatic feeder device 9 has a tape insertion port 91 near the mid-height of the rear end, and an insertion lever 92 near the upper part of the rear end. By lifting the insertion lever 92, the first and second component storage tapes 85, 86 can be inserted in order into the tape insertion port 91. A payout rail 93 is disposed from the tape insertion port 91 of the automatic feeder device 9 toward the upper part of the front end. A supply position 94 is set on the upper surface of the payout rail 93 near the front end. A standby position 96 is set on the upper surface of the payout rail 93 near the rear, close to the tape insertion port 91. The inserted first and second component storage tapes 85, 86 advance to the standby position 96 and stop temporarily.

A tape control unit 95 is provided above the standby position 96. The tape control unit 95 allows the first component storage tape 85 to be unwound from the standby position 96, and keeps the second component storage tape 86 on standby. Furthermore, when the first component storage tape 85 runs out, the tape control unit 95 automatically allows the second component storage tape 86 to be unwound from the standby position 96. Therefore, no splicing work is required to connect the first and second component storage tapes 85, 86. A specific configuration of the tape control unit 95 is disclosed, for example, in JP 2014-82454 A.

The automatic feeder device 9 further includes a tape unwinding mechanism (not shown) that is composed of a servo motor, a sprocket, and the like. When the first component storage tape 85 is inserted up to the standby position 96, the automatic feeder device 9 drives the servo motor in the forward direction. As a result, the automatic feeder device 9 automatically unwinds and loads the first component storage tape 85, and preparations for production of the board K are completed. In other words, the automatic feeder device 9 has an automatic loading function. The second component storage tape 86 may be inserted immediately after the first component storage tape 85 is inserted, or may be inserted while production is being performed using the first component storage tape 85.

When the automatic feeder device 9 receives an ejection command, it drives the servo motor in the reverse direction. As a result, the automatic feeder device 9 ejects the cut end of the first or second component storage tape 85, 86 from the supply position 94 toward the tape insertion port 91. In other words, the automatic feeder device 9 has an automatic ejection function. The ejection command is issued from the control device 16, or is issued when an operator presses an unillustrated ejection button attached to the automatic feeder device 9. The automatic feeder device 9 is equipped with a tape control unit 95 and has an automatic loading function and an automatic ejection function, which greatly reduces the effort required for reel replacement work. The applicant of the present application has already filed detailed configuration examples of the automatic feeder device 9 in International Application JP2014/064443 and International Application JP2014/083619, etc.

The reel mounting section 55 of the common pallet 5 is composed of two arm members 56 and a connecting member 59. The two arm members 56 are fixed to the rear of both sides of the feeder mounting section 51 in the width direction. The arm members 56 are formed to initially extend horizontally backward, then extend at an angle downward and rearward, and finally extend horizontally backward. The two arm members 56 are connected at their rear ends by a connecting member 59, ensuring that they are arranged in parallel. A small plate-shaped front mounting seat 57 is provided on the upper side of the inclined portion of each of the two arm members 56. A plate-shaped rear mounting seat 58 that is long in the front-rear direction is provided on the upper side of the horizontal portion at the rear of each of the two arm members 56 (see FIG. 2). The reel holding device 1 is detachably attached to the upper side of the front mounting seat 57 and the rear mounting seat 58.

(2. Configuration of the reel holding device 1 of the first embodiment)
Next, the configuration of the reel holding device 1 of the first embodiment will be described. The reel holding device 1 is made up of a reel holding section 2 and an attachment section 3. The reel holding section 2 is made up of two sets of front side plates 21 and rear side plates 22, a number of partition plates 24, and a number of outer periphery support rollers 26. The front side plate 21 is formed of a plate material that is higher at the front and has an upper edge that gradually drops toward the rear.

A tilted front mounting plate 31 is provided near the lower front side of the front side plate 21. A rear mounting plate 32, which is long in the front-to-rear direction, is provided at the bottom of the front side plate 21. The front mounting plate 31 is attached to the front mounting seat 57 of the reel mounting part 55, and the rear mounting plate 32 is attached to the rear mounting seat 58 of the reel mounting part 55. An example of a mounting method is a fixing method using screws, but is not limited to this. The front mounting plate 31 and the rear mounting plate 32 correspond to the mounting part 3.

The rear side plate 22 is connected to and positioned directly behind the front side plate 21, and is smaller than the front side plate 21. The rear side plate 22 is formed of a plate material that is low at the front and the upper edge gradually rises toward the rear. The two sets of front side plates 21 and rear side plates 22 are positioned parallel to each other and spaced apart by the width dimension in which the 20 automatic feeder devices 9 are arranged in a row.

A number of partition plates 24 are arranged parallel and at equal intervals between two sets of parallel front side plates 21 and rear side plates 22. The spacing dimension D (see FIG. 2) between adjacent partition plates 24 matches the row pitch of the automatic feeder device 9. In addition, the spacing dimension D between the end partition plate 24 and the front side plate 21 and rear side plate 22 also matches the row pitch of the automatic feeder device 9.

A first reel support portion 41 is formed near the front of the space between adjacent partition plates 24, and a second reel support portion 42 is formed near the rear of the space. Similarly, a first reel support portion 41 and a second reel support portion 42 are formed between the end partition plates 24 and the front side plate 21 and the rear side plate 22. In the first embodiment, 19 partition plates 24 are arranged to accommodate the 20 automatic feeder devices 9, and there are 20 first reel support portions 41 and 20 second reel support portions 42.

Two outer peripheral support rollers 261, 262 (shown by broken lines) are arranged at a distance from each other on the lower front and rear sides of the first reel support portion 41. The outer peripheral support rollers 261, 262 are rotatably supported by shaft members 271, 272, respectively. The shaft members 271, 272 are suspended between the front side plates 21 on both sides and pass through the partition plate 24. Similarly, two outer peripheral support rollers 263, 264 are arranged at a distance from each other on the lower front and rear sides of the second reel support portion 42. The outer peripheral support rollers 263, 264 are rotatably supported by shaft members 273, 274, respectively. The shaft member 273 is suspended between the front side plates 21 on both sides and passes through the partition plate 24. The shaft member 274 is suspended between the rear side plates 22 on both sides and passes through the partition plate 24.

The first and second component supply reels 81, 82 are set on the upper side of the two outer periphery support rollers 261-264 of the first reel support portion 41 and the second reel support portion 42, respectively. Each of the two outer periphery support rollers 261-264 rotatably holds the outer periphery of the first and second component supply reels 81, 82, respectively. The first and second reel support portions 41, 42 can hold first and second component supply reels 81, 82 of different sizes. However, the outer diameter dimensions of the first and second component supply reels 81, 82 are limited to a range that is larger than the separation distance between the two outer periphery support rollers 261-264 and does not contact the reels 81, 82 arranged in front and behind each other.

The four shaft members 271-274 support each partition plate 24. This determines the shape of the reel holding device 1. Each shaft member 271-274 may be divided into multiple members, and the position of each divided shaft member may be changed. This allows for a configuration suitable for multiple component supply reels 81, 82 with different outer diameter dimensions. Alternatively, the outer periphery support rollers 261-264 may be omitted, and the shaft members 271-274 may directly hold the outer peripheries of the first and second component supply reels 81, 82 for rotation.

(3. Configuration of the reel holding device 10 of the second embodiment)
Next, the configuration of the reel holding device 10 of the second embodiment will be described. In the second embodiment, the component mounter is large in the width direction, and 40 automatic feeder devices 9 are arranged in a row on the feeder mounting section 51 of the common pallet 5. FIG. 3 is a rear view of the reel holding device 10 of the second embodiment. In the reel holding device 10 of the second embodiment, the component holding section is divided into two parts in the width direction, a first component holding section 2A and a second component holding section 2B. In addition, the common pallet 5 has two sets of reel mounting sections 55A and 55B so that the first and second component holding sections 2A and 2B can be individually and detachably mounted. Since the reel holding device 10 of the second embodiment is structurally roughly the same as two reel holding devices 1 of the first embodiment arranged in the width direction, detailed description will be omitted.

The number of first and second reel support parts 41, 42 in the reel holding parts 2, 2A, 2B of the first and second embodiments can be increased or decreased. For example, a configuration with only the first reel support part 41 without the second reel support part 42 may be used. Also, as shown in FIG. 4, a reel holding device 11 of the third embodiment having only one first and second reel support part 41, 42 in the width direction is also conceivable. FIG. 4 is a rear view of the reel holding device 11 of the third embodiment. This reel holding device 11 does not have a partition plate 24, and the first and second reel support parts 41, 42 are formed between two sets of front side plates 21 and rear side plates 22.

(4. Method of Using the Reel Holding Devices 1, 10 of the First and Second Embodiments)
Next, a method of using the reel holding devices 1 and 10 of the first and second embodiments will be described. As a prerequisite, the common pallet 5 is in a state where it is mounted on the machine base 19. Prior to the operation of the component mounter, an operator first mounts a plurality of automatic feeder devices 9 on the common pallet 5. FIG. 5 is a diagram showing a method of mounting the automatic feeder devices 9. As shown in the figure, in the initial state, neither the automatic feeder devices 9 nor the reel holding devices 1 and 10 are mounted on the common pallet 5. In this state, an operator inserts the plurality of automatic feeder devices 9 from the rear of each slot 54 of the flat portion 52 of the feeder mounting portion 51 toward the front upright portion 53 as shown by the arrow M1, and mounts them. After this, the automatic feeder devices 9 are not removed from the common pallet 5 in principle.

Next, the worker sets the first and second component supply reels 81, 82 on the first and second reel support parts 41, 42 of the reel holding device 1, 10 outside the component mounting machine. Generally, the order of component types allocated to the multiple automatic feeder devices 9 arranged on the common pallet 5 is optimized according to the type of board to be produced. Therefore, the worker determines the order of the multiple first and second component supply reels 81, 82 in accordance with the optimized order of component types. In addition, the first and second component supply reels 81, 82 on which first and second component storage tapes 85, 86 containing the same component type are wound are set on the first reel support part 41 and the second reel support part 42 arranged in front and behind each other.

Next, the worker carries the reel holding devices 1, 10, on which the first and second component supply reels 81, 82 are set, to the component mounting machine. Furthermore, the worker attaches the front mounting plate 31 and rear mounting plate 32 (mounting section 3) of the reel holding devices 1, 10 to the upper side of the front mounting seat 57 and rear mounting seat 58 of the reel mounting section 51. This results in the arrangement shown in FIG. 1.

Next, the worker pulls out the first component storage tape 85 from the first component supply reel 81 of the first reel support portion 41, and inserts it from the tape insertion port 91 of the automatic feeder device 9 to the standby position 96. Next, the worker pulls out the second component storage tape 86 from the second component supply reel 82 of the second reel support portion 42, and inserts it from the tape insertion port 91 to the standby position 96. This activates the automatic loading function of the automatic feeder device 9, which then starts unwinding the first component storage tape 85, and starts the production of the board.

When changing the type of board to be produced, the worker prepares replacement reel holding devices 1C, 10C. FIG. 6 is a diagram explaining a method of changeover work for changing the type of components to be supplied when changing the type of board to be produced. The worker pre-loads the first and second component supply reels 81C, 82C corresponding to the multiple component types required for the next type of board to be produced in the replacement reel holding devices 1C, 10C. In this case, too, the worker determines the order of the multiple first and second component supply reels 81C, 82C in correspondence with the order of the component types optimized for the next board to be produced.

Meanwhile, the automatic feeder device 9 mounted on the common pallet 5 uses its automatic discharge function to discharge the partially used first or second component storage tape 85, 86. If necessary, the worker reverses the first and second component supply reels 81, 82 to wind up the partially used first and second component storage tapes 85, 86. Then, as shown by arrow M2, the worker removes the mounted reel holding devices 1, 10 and mounts replacement reel holding devices 1C, 10C. After that, the component storage tape is pulled out from the first and second component supply reels 81C, 82C of the replacement reel holding devices 1C, 10C and inserted from the tape insertion port 91 of the automatic feeder device 9 to the standby position 96. This completes the changeover operation.

In addition, in the reel holding device 10 equipped with the first and second component holding units 2A and 2B of the second embodiment, there are three types of changeover methods, as shown below.

1) Replace the first component holder 2A and the second component holder 2B at the same time. This method is used when there are few common component types between the board currently being produced and the next board to be produced, and the number of component types to be changed exceeds 20.

2) The first component holding unit 2A and the second component holding unit 2B are alternately replaced. This method can be implemented when 20 or fewer component types are required for each of the multiple types of boards to be produced. For example, components are supplied from the first component holding unit 2A to board type A, and components are supplied from the second component holding unit 2B to the next board type B. Then, for the next board type C, the first component holding unit 2A is replaced and the setup is changed. Furthermore, for the next board type D, the second component holding unit 2B is replaced and the setup is changed, and for the next board type E, the first component holding unit 2A is replaced again and the setup is changed. With this method, there is no need to replace the entire component holding unit when changing the setup, improving work efficiency.

3) The first component holding unit 2A is fixedly attached, and only the second component holding unit 2B is replaced. This method can be implemented when there are 20 or less types of common generic components and 20 or less types of components specific to each board type in the multiple types of boards being produced. In this case, the first and second component supply reels 81, 82 corresponding to the generic components are set in the first component holding unit 2A, which is fixedly attached. Meanwhile, the first and second component supply reels 81, 82 corresponding to the unique components are set in the second component holding unit 2B, which is replaced sequentially. With this method, there is no need to replace the entire component holding unit during a changeover operation, improving work efficiency.

When a certain component type runs out during the production of a board, it is sufficient to replace only the first and second component supply reels 81, 82 in question while the reel holding devices 1, 10 are attached to the common pallet 5. In this case, too, the automatic ejection and loading functions reduce the burden on the worker.

(5. Aspects and Effects of the Reel Holding Devices 1, 10 of the First and Second Embodiments)
The reel holding device 1, 10 of the first and second embodiments is a reel holding device 1, 10 used in combination with a plurality of automatic feeder devices 9 having an automatic loading function that automatically loads component storage tapes 85, 86 when the component storage tapes 85, 86 containing components are inserted into a plurality of component storage sections, and includes reel holding units 2, 2A, 2B that rotatably and interchangeably hold a plurality of component supply reels 81, 82 around which the plurality of component storage tapes 85, 86 are wound, and an attachment unit 3 that detachably attaches the reel holding units 2, 2A, 2B to a common pallet 5 on which the plurality of automatic feeder devices 9 are arranged in a row and which is equipped to a component mounting machine.

In the first and second embodiments, each component supply reel 81C, 82C corresponding to a plurality of types of components required for the next board type to be produced can be held in advance in the replacement reel holding device 1C, 10C. This allows a smaller number of reel holding devices 1C, 10C to be replaced during the changeover work than the number of reels, and the changeover time can be shortened compared to the conventional technology in which a large number of individual reels are replaced. In addition, although it is necessary to prepare replacement reel holding devices 1C, 10C, a replacement automatic feeder device 9 is not required. This allows the number of automatic feeder devices 9, which are more expensive than the reel holding devices 1, 10, to be reduced compared to the conventional technology in which a plurality of feeder devices are replaced at once. Therefore, it is possible to achieve both high work efficiency and production efficiency during the changeover work and suppression of equipment costs.

Furthermore, in the first and second embodiments, the arrangement order of the multiple component supply reels 81, 82 held in the reel holding units 2, 2A, 2B corresponds to the arrangement order of the component types allocated to the multiple automatic feeder devices 9 arranged in a row on the common pallet 5. This automatically associates the arrangement order of the component supply reels 81, 82 with the arrangement order of the component types, reducing the risk of operational errors. In addition, the verification process of confirming that the allocated component types match the actual component types of the component supply reels 81, 82 is easy and can be performed in a short time.

Furthermore, in the second embodiment, the reel holding section is divided into multiple sections, and the mounting section 3 mounts the multiple divided reel holding sections 2A, 2B in an individually detachable manner. This allows the efficient use of the multiple reel holding sections 2A, 2B in accordance with the type of board being produced. For example, any of the following methods can be adopted: a method of simultaneously replacing the first component holding section 2A and the second component holding section 2B all at once, a method of replacing them alternately, or a method of fixing one and replacing only the other. This further improves the efficiency of work during changeover work.

Furthermore, in the first and second embodiments, the automatic feeder device 9 can insert a first component storage tape 85 and a second component storage tape 86 that store the same type of components, and automatically pays out the inserted first component storage tape 85 while keeping the inserted second component storage tape 86 on standby, and when the first component storage tape 85 runs out, automatically starts paying out the second component storage tape 86, and the reel holding unit 3 holds two component supply reels 81, 82 on which the first component storage tape 85 and the second component storage tape 86 are wound, respectively, for each automatic feeder device 9.

This allows the reel holding devices 1, 10 to be used in combination with the automatic feeder device 9, which does not require splicing work. With this combination, it is only necessary to line up multiple component supply reels 81C, 82C on the replacement reel holding devices 1C, 10C during off-machine changeover. In addition, during on-machine changeover when the reel holding devices 1C, 10C are attached to the common pallet 5, the automatic loading and discharging functions of the automatic feeder device 9 are activated. This further significantly improves the work efficiency during changeover work.

(6. Reel exchange device 6 of embodiment)
Next, the reel changing device 6 of the embodiment will be described. Fig. 7 is a side view of the reel changing device 6 of the embodiment. The reel changing device 6 supports the changing work of the reel holding devices 1 and 10 of the first and second embodiments. The reel changing device 6 is generally in the shape of a cart, and is composed of a cart main body 61, a mounting table 66, and the like.

The cart main body 61 consists of a bottom plate 611 and a body 612 that stands up from the rear of the bottom plate 611. A pair of front wheels 613, whose direction of travel is fixed, are provided near the front of the underside of the bottom plate 611 (on the right side in FIG. 7). A pair of rear wheels 614, whose direction of travel can be changed, are provided near the rear of the underside of the bottom plate 611 (on the left side in FIG. 7). A slide holder 62 is provided on the top of the body 612. A height adjustment lever 63 protrudes from the rear side of the body 612 toward the rear and upward. The height adjustment lever 63 has a function of adjusting the height of the slide holder 62. A handle 64 with a brake extends upward from the rear side of the body 612.

The mounting table 66 is held by the slide holder 62 so that it can slide forward and backward and cannot fall off. The upper surface of the mounting table 66 is designed to be able to mount the reel holding devices 1, 1C, 10, and 10C, as shown by the dashed line in FIG. 7. The height H of the upper surface of the mounting table 66 from the floor surface FL is approximately equal to the height of the rear mounting seat 58 of the reel mounting section 55 of the common pallet 5. If they do not match, the operator can adjust the height H of the mounting table 66 by operating the height adjustment lever 63. The operator pushes the handle 64 to move the reel exchange device 6 and transport the reel holding device 1, 1C, 10, and 10C on the mounting table 66.

In the replacement work of the reel holding devices 1, 1C, 10, and 10C, the worker prepares the first reel exchange device 6 with nothing placed on the top surface of the mounting base 66, and the second reel exchange device 6 with the replacement reel holding devices 1C and 10C placed on the top surface of the mounting base 66. The worker first moves the first reel exchange device 6 to the rear of the common pallet 5 of the component mounting machine. The worker then removes the mounted reel holding devices 1 and 10 from the common pallet 5 and places them on the mounting base 66 of the first reel exchange device 6. The worker moves the first reel exchange device 6 away from the common pallet 5 and moves the second reel exchange device 6 to the rear of the common pallet 5 instead. The worker then mounts the replacement reel holding devices 1C and 10C placed on the mounting base 66 of the second reel exchange device 6 to the common pallet 5. This completes the replacement work for reel holding devices 1, 1C, 10, and 10C.

It is also possible to adopt a configuration in which one reel exchange device 6 is provided with two sets of slide holding parts 62 and mounting tables 66.
