The adherend WK (the same adherend WK) is counted (numbered) as 1, and thereafter every time all subsequent adherends WK are detected, they are sequentially counted with the same integer number following 1. It's becoming Then, the control device 53 recognizes and identifies the adherend WK having the same count number by the first detection device 51 and the same count number by the second detection device 52 as the same object. As a result, the first and second sticking means 10 and 20 operate to eliminate non-sticking and double sticking of the first and second adhesive sheets AS1 and AS2 to the adherend WK specified by the control device 53. is controlled.

The operation of the above sheet sticking apparatus EA will be described.
First, a user of the sheet sticking device EA (hereinafter simply referred to as the "user") moves the sheet sticking device EA in which the respective members are arranged at the initial positions indicated by the solid lines in FIG. , the first and second raw fabrics RS1, RS2 and the fourth raw fabric RS4 are set. Also, after the user pulls out the support base 42 and fits the third support pipe RS3P on the support shaft 42A to stack the third raw fabric RS3 on the support base 42, the support base 42 is returned to the initial position. . The lead end RS3T of RS3 is temporarily fixed with an adhesive tape (not shown).
When the above work is completed, the user inputs a signal for starting automatic operation via an operation means (not shown) such as an operation panel or a personal computer. Then, the first and second pasting means 10 and 20 drive the rotating motors 15A and 25A to feed the first and second original sheets RS1 and RS2, thereby feeding the leading first and second adhesive sheets AS1 and AS2. When the direction leading edge is peeled off by the peeling edges 13A, 23A of the peeling plates 13, 23 for a predetermined length, the rotation motors 15A, 25A are stopped. Further, when the connecting means 30 drives the rotating motor 32K to feed the fourth material RS4 and the leading end of the leading connecting tape CT in the feeding direction reaches a predetermined position near the peeling edge 32D of the peeling plate 32C, the rotating motor 32K rotates. Stop driving 32K.

Next, after the adherend WK conveyed by the adherend conveying means 60 is detected by the first detection device 51 and counted, when it reaches a predetermined position with respect to the first sticking means 10, the first sticking means 10 drives the rotating motor 15A, and feeds out the first web RS1 in accordance with the moving speed of the adherend WK. As a result, the first adhesive sheet AS1 is peeled off from the first release sheet RL1, and the first adhesive sheet AS1 peeled off from the first release sheet RL1 is pressed as indicated by the chain double-dashed line in FIG. The roller 14 presses and adheres to the adherend WK. After that, the entire first adhesive sheet AS1 at the head is attached to the adherend WK, and the leading end of the first adhesive sheet AS1 next to the first adhesive sheet AS1 in the delivery direction is the release edge 13A of the release plate 13. After peeling for a predetermined length, the first sticking means 10 stops driving the rotating motor 15A, and the same operation as described above is repeated thereafter.

After that, the transport of the adherend WK by the adherend transport means 60 is continued, and when the adherend WK is detected by the second detection device 52 and counted, the control device 53 detects the number counted by the first detection device 51. , and the number counted by the second detector 52 to identify the adherend WK, and determine whether the first adhesive sheet AS1 has been applied by the first applying means 10 or not. Next, the control device 53 outputs a drive stop signal to the second sticking means 20 for the adherend WK to which the first adhesive sheet AS1 has been stuck, determined by the control device 53. By doing so, the second adhesive sheet AS2 is not stuck by the second sticking means 20 . On the other hand, the control device 53 outputs a driving signal to the second sticking means 20 for the adherend WK that is determined to not have the first adhesive sheet AS1 stuck thereon by the control device 53. Thus, the second adhesive sheet AS2 is stuck by the second sticking means 20 in the same manner as the first sticking means 10, and the same operation as described above is repeated thereafter.

The above operation is repeated, and as shown in FIG. Then, the sticking operation by the first sticking means 10 is stopped, and the sticking operation by the second sticking means 20 is started. Due to this switching, the adherend WK to which the first adhesive sheet AS1 has not been attached by the first attaching means 10 is specified by the determination by the control device 53 described above. Non-application and duplicate application do not occur. Then, the first pasting means 10 drives the rotary motor 15A to feed out the first substrate RS1, and as shown in FIG. When detecting means (not shown) composed of various sensors or the like detects this, the first pasting means 10 stops driving the rotating motor 15A. At this time, the first sticking means 10 may drive a decompressing means (holding means) (not shown) such as a decompression pump or a vacuum ejector, and the first material RS1 may be adsorbed and held by the material guide plate 11H. Next, the first pasting means 10 drives the direct-acting motor 11K, and as shown by the solid line in FIG. After forming the end portion RS1R, the cutting blade 11M is returned to the initial position. A portion of the first raw fabric RS1 including the final end RS1E cut off by cutting with the cutting blade 11M is removed by the user or a conveying means (not shown). After that, the first pasting means 10 drives the rotating motor 15A to let out the first material sheet RS1, and as shown in FIG. When the detecting means (not shown) composed of a sensor or the like detects this, the first pasting means 10 stops driving the rotation motor 15A. At this time, the first pasting means 10 may drive a decompressing means (holding means) (not shown) such as a decompressing pump or a vacuum ejector, and the original fabric guide plate 11H may adsorb and hold the connection rear end portion RS1R.

Next, the connecting means 30 drives the articulated robot 31H and the linear motor 31K, the chuck arm 31M grips the first support pipe RS1P, and the first receiving plate RS1B and the first support pipe RS1P are moved into the collection case 11N. throw into. Then, the first pasting means 10 and the supply means 40 drive the linear motor 11A and the linear motor 49 to lower the support plate 11C to pass under the original fabric guide plate 11H. The support plate 11C is moved directly below the linear motor 46 as indicated by the two-dot chain line. Next, the supply means 40 drives the linear motors 43 and 44, and as shown by the two-dot chain line in FIG. 45 is moved, the lift arm 45 is raised to lift the third raw fabric RS3 together with the third receiving plate RS3B to a predetermined height. After that, the supply means 40 drives the linear motor 46, the direct-acting motor 47, and the decompression means (not shown), and as indicated by the two-dot chain line in FIG. Then, suction holding of the third receiving plate RS3B by the suction pad 48 is started. Next, the supply means 40 drives the linear motors 43 and 44 to return the lift arm 45 to the initial position, and drives the linear motor 46 and the direct-acting motor 47, which are indicated by two-dot chain lines in FIG. 2(A). , the third support pipe RS3P is fitted onto the support shaft 11D, and the third raw fabric RS3 is placed on the support plate 11C. Then, after the supplying means 40 stops driving the depressurizing means (not shown) and releases the suction holding of the third receiving plate RS3B by the suction pad 48, the linear motor 46 and the direct-acting motor 47 are driven to move the suction pad 48. return to the initial position.

Next, the first pasting means 10 drives the direct-acting rotary motor 11A to rotate the support plate 11C at a predetermined speed, and as shown by the two-dot chain line in FIG. When the end RS3T is detected, the detection result is output to the first sticking means 10, and as indicated by the chain double-dashed line in FIG. The driving of the linear motion rotation motor 11A is stopped. After that, the connection means 30 drives the direct-acting motor 31B and the decompression means (not shown), and as indicated by the chain double-dashed line in FIG. As shown in , when the detection means (not shown) composed of various sensors or the like detects that the center of the third adhesive sheet AS3 is positioned directly above the cutting blade 31G after pulling out the third material sheet RS3, the linear motion motor 31B is stopped. Next, the connection means 30 drives the multi-joint robot 31H and the linear motor 31K, and as shown in FIG. As shown in FIG. 2B, the cutting blade 31G is slid along the cutting reference side 31N of the chuck arm 31M to cut the third material RS3, thereby forming the connecting tip portion RS3F on the third material RS3. do. Then, after the connecting means 30 drives the direct-acting motors 31B and 31E to return the suction pad 31D and the cutting blade 31G to their initial positions, the driving of the decompression means (not shown) is stopped, and the suction pad 31D performs the third adhesion. The suction holding of the sheet AS3 is released. A portion of the third raw fabric RS3 including the lead end RS3T cut off by cutting with the cutting blade 31G is removed by the user or a conveying means (not shown).

Next, the first pasting means 10 and the supply means 40 drive the linear motor 11A and the linear motor 49 to cause the support plate 11C to pass under the material guide plate 11H and return to the initial position. At this time, the connecting means 30 drives the articulated robot 31H to guide the pulled-out third material RS3 so that it does not get caught on the material guide plate 11H or the like. When the support plate 11C returns to the initial position, the connection means 30 drives the articulated robot 31H, and as shown in FIG. It is moved to bring the cutting reference side 31N into close contact with the connection reference position 11E, and the connection rear end RS1R of the first raw material RS1 and the connection front end RS3F of the third raw material RS3 are aligned and positioned. After that, the connecting means 30 drives the rotation motor 32K and the decompressing means (not shown) to let out the fourth raw material RS4, and the leading connecting tape CT is peeled off by the peeling edge 32D of the peeling plate 32C. When the leading end of the next connecting tape CT in the delivery direction reaches a predetermined position near the peeling edge 32D of the peeling plate 32C, the rotation motor 32K is stopped. As a result, the connecting tape CT is sucked and held by the holding member 32J, as shown in FIG. 2(C). Next, the connecting means 30 drives the linear motor 32E to press the connecting tape CT against the first release sheet RL1 and the third release sheet RL3 as indicated by the two-dot chain lines in FIGS. 2(C) and 2(D). After affixing, the depressurizing means (not shown) stops driving to return the holding member 32J to the initial position, and the connecting means 30 drives the articulated robot 31H and the linear motor 31K to move the pair of chuck arms 31M to the initial position. return to As a result, the third web RS3 is connected to the first web RS1 by the connecting tape CT, and the third web RS3 connected to the first web RS1 becomes the first web RS1. The accompanying third receiving plate RS3B and third support pipe RS3P become the first receiving plate RS1B and first support pipe RS1P.

After that, the operation of attaching the second adhesive sheet AS2 by the second attaching means 20 is performed, the final edge RS2E of the second raw fabric RS2 is separated from the second support pipe RS2P, and the final edge RS2E is detected. When detected by the device 27, the sticking operation by the second sticking means 20 is stopped after the sticking action by the first sticking means 10 is started. As a result of this switching, the adherend WK to which the first adhesive sheet AS1 is attached by the first attaching means 10 is specified by the determination by the control device 53, and therefore it is specified that the first adhesive sheet AS1 is attached. The control device 53 outputs a drive stop signal to the second sticking means 20 for the adherend WK, and the second sticking means 20 does not stick the second adhesive sheet AS2. As a result, the first adhesive sheet AS1 or the second adhesive sheet AS2 is not adhered to the adherend WK and is not adhered repeatedly.
The operation of connecting the connection front end portion RS3F of the third raw material RS3 to the connection rear end portion RS2R of the second raw material RS2 is performed by sucking and holding the connection tape CT as indicated by the two-dot chain line in FIG. 2(D). The holding member 32J descends once, passes under the material guide plate 11H, and then rises again to adhere the held connecting tape CT to the second release sheet RL1 and the third release sheet RL3. Since the operation is the same as the operation of connecting the connecting rear end portion RS1R of the first raw material RS1 to the connecting front end portion RS3F of the third raw material RS3, the explanation of the operation is omitted.
