The supply means 40 is supported by the slider 41A of the rail 41, and includes a support base 42 that supports on its upper surface the support shaft 42A into which the third support tube RS3P fits, a linear motor 44 as a driving device supported by the slider 43A of the linear motor 43 as a driving device, a pair of lift arms 45 supported on each of the two sliders 44A of the linear motor 44, a linear motor 47 as a driving device supported by the slider 46A of the linear motor 46 as a driving device, a suction pad 48 that is supported by the output shaft 47A of the linear motor 47 via a frame material 48A and can be suctioned and held by a pressure reduction means (holding means) such as a pressure reduction pump or a vacuum ejector (not shown), and a linear motor 49 as a driving device that supports the linear rotation motor 11A with the first slider 49A and supports the linear rotation motor 21A with the second slider 49B.

The application control means 50 includes a first detection device 51 composed of various sensors, a second detection device 52 equivalent to the first detection device 51, and a control device 53 such as a computer or sequencer capable of controlling the operation of the first and second detection devices 51, 52 and each of the means constituting the sheet application device EA. The first and second detection devices 51, 52 count (number) the first substrate WK (the same substrate WK) detected by each of them as 1 for the substrate WK conveyed from the left to the right of the first detection device 51 by the substrate conveying means 60, and thereafter, each of them counts sequentially with the same integer number following 1 each time it detects all the subsequent substrates WK. The control device 53 recognizes and identifies substrates WK whose count numbers by the first detection device 51 and the second detection device 52 are the same as one another. As a result, the operation of the first and second attachment means 10, 20 is controlled so as to prevent the first and second adhesive sheets AS1, AS2 from being left unattached or overlapped on the adherend WK identified by the control device 53.

The operation of the sheet sticking apparatus EA will now be described.
First, a user of the sheet application device EA (hereinafter simply referred to as the "user") sets the first and second webs RS1, RS2 and the fourth web RS4 on the sheet application device EA, in which each component is arranged in the initial position shown by the solid lines in Fig. 1(A). The user also pulls out the support base 42, fits the third support tube RS3P onto the support shaft 42A, stacks the third web RS3 on the support base 42, and then returns the support base 42 to its 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 to start automatic operation via an operation means (not shown) such as an operation panel or a personal computer. Then, the first and second attaching means 10, 20 drive the rotating motors 15A, 25A to pay out the first and second original rolls RS1, RS2, and when the leading end of the leading first and second adhesive sheets AS1, AS2 in the payout direction is peeled off a predetermined length by the peeling edges 13A, 23A of the peeling plates 13, 23, the driving of the rotating motors 15A, 25A is stopped. In addition, the connecting means 30 drives the rotating motor 32K to pay out the fourth original roll RS4, and when the leading end of the leading connection tape CT in the payout direction reaches a predetermined position near the peeling edge 32D of the peeling plate 32C, the driving of the rotating motor 32K is stopped.

Next, when the adherend WK transported by the adherend transport means 60 is detected and counted by the first detector 51 and reaches a predetermined position relative to the first attaching means 10, the first attaching means 10 drives the rotary motor 15A to pay out the first original roll 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 by the pressure roller 14 onto the adherend WK and attached thereto, as shown by the two-dot chain line in FIG. 1A. After that, the entire first adhesive sheet AS1 at the top is attached to the adherend WK, and when the leading end of the next first adhesive sheet AS1 following the first adhesive sheet AS1 in the payout direction is peeled off by a predetermined length at the peeling edge 13A of the peeling plate 13, the first attachment means 10 stops driving the rotating motor 15A, and the same operation as above is repeated thereafter.

After that, the transport of the adherend WK by the adherend transport means 60 continues, and when the adherend WK is detected and counted by the second detection device 52, the control device 53 identifies the adherend WK from the count numbers by the first detection device 51 and the second detection device 52, and determines whether the first adhesive sheet AS1 has been attached by the first attachment means 10 or not. Next, for the adherend WK identified by the control device 53 as having the first adhesive sheet AS1 attached, the control device 53 outputs a drive stop signal to the second attachment means 20, so that the second attachment means 20 does not attach the second adhesive sheet AS2. On the other hand, for adherends WK that are determined by the control device 53 to not have the first adhesive sheet AS1 attached, the control device 53 outputs a drive signal to the second attachment means 20, causing the second attachment means 20 to attach the second adhesive sheet AS2 in the same manner as the first attachment means 10, and the same operations as described above are then repeated.

The above operation is repeated, and when the final end RS1E of the first original roll RS1 comes off the first support tube RS1P as shown in FIG. 1B and the final end RS1E is detected by the final end detector 17, the first attaching means 10 stops attaching the first adhesive sheet AS1 and the second attaching means 20 starts attaching the second adhesive sheet AS2. The first attaching means 10 drives the rotary motor 15A to unroll the first original roll RS1, and when the detector (not shown) composed of various sensors detects that the center between the first adhesive sheets AS1 is located to the right of the cutting blade 11M as shown in FIG. 1B, the first attaching means 10 stops driving the rotary motor 15A. At this time, the first attaching means 10 may drive a decompression means (holding means) such as a decompression pump or a vacuum ejector (not shown) to suction and hold the first original web RS1 with the original web guide plate 11H. Next, the first attaching means 10 drives the linear motor 11K to cut the first original web RS1 with the cutting blade 11M as shown by the solid line in Fig. 1 (B) to form a connection rear end portion RS1R on the first original web RS1, and then returns the cutting blade 11M to its initial position. The portion of the first original web RS1 including the final end portion RS1E cut off by the cutting blade 11M is removed by the user or a conveying means (not shown). Thereafter, the first attachment means 10 drives the rotary motor 15A to pay out the first original web RS1, and when a detection means (not shown) composed of various sensors detects that the connection rear end RS1R has reached the connection reference position 11E as shown in FIG. 2C, the first attachment means 10 stops driving the rotary motor 15A. At this time, the first attachment means 10 may drive a pressure reduction means (holding means) (not shown) such as a pressure reduction pump or vacuum ejector, and the original web guide plate 11H may suction and hold the connection rear end RS1R.

Next, the connection means 30 drives the articulated robot 31H and the linear motor 31K to grip the first support tube RS1P with the chuck arm 31M, and inserts the first receiving plate RS1B and the first support tube RS1P into the recovery case 11N. Then, the first attachment means 10 and the supply means 40 drive the linear rotation motor 11A and the linear motor 49 to lower the support plate 11C so that it passes under the original fabric guide plate 11H, and move the support plate 11C directly below the linear motor 46, as shown by the two-dot chain line in FIG. 1(A). Next, the supply means 40 drives the linear motors 43, 44 to move the lift arm 45 below the uppermost third receiving plate RS3B fitted on the support shaft 42A as shown by the two-dot chain line in Fig. 1(C), and then raises the lift arm 45 to lift the third original web RS3 together with the third receiving plate RS3B to a predetermined height. Thereafter, the supply means 40 drives the linear motor 46, the direct-acting motor 47, and a pressure reducing means (not shown) to bring the suction pad 48 into contact with the upper surface of the third receiving plate RS3B as shown by the two-dot chain line in Fig. 1(C), and the suction pad 48 begins to suction and hold the third receiving plate RS3B. Next, the supply means 40 drives the linear motors 43 and 44 to return the lift arm 45 to its initial position, and drives the linear motor 46 and the linear motor 47 to fit the third support tube RS3P onto the support shaft 11D as shown by the two-dot chain line in FIG. 2A, and place the third original roll RS3 on the support plate 11C. Then, the supply means 40 stops driving the decompression means (not shown) and releases the suction hold of the third support plate RS3B by the suction pad 48, and then drives the linear motor 46 and the linear motor 47 to return the suction pad 48 to its initial position.

Next, the first attachment means 10 drives the linear motor 11A to rotate the support plate 11C at a predetermined speed, and when the lead end detector 31A detects the lead end RS3T as shown by the two-dot chain line in Fig. 2B, it outputs the detection result to the first attachment means 10, and when the vicinity of the lead end RS3T is located at the suction position of the suction pad 31D as shown by the two-dot chain line in the same figure, it stops driving the linear motor 11A. After that, the connection means 30 drives the linear motor 31B and the pressure reducing means (not shown), and after the vicinity of the lead end RS3T is suction-held by the suction pad 31D as shown by the two-dot chain line in Fig. 2B, the third original roll RS3 is pulled out as shown in the figure, and when the detection means (not shown) composed of various sensors detects that the center between the third adhesive sheets AS3 is located directly above the cutting blade 31G, it stops driving the linear motor 31B. Next, the connecting means 30 drives the articulated robot 31H and the linear motor 31K, and as shown in FIG. 2A, the chuck arm 31M grips the third original roll RS3, and then drives the linear motor 31E, and as shown in FIG. 2B, the cutting blade 31G slides along the cutting reference side 31N of the chuck arm 31M to cut the third original roll RS3, forming a connection tip RS3F on the third original roll RS3. Then, the connecting means 30 drives the linear motors 31B and 31E to return the suction pad 31D and the cutting blade 31G to their initial positions, and then stops driving the pressure reducing means (not shown), and releases the suction and holding of the third adhesive sheet AS3 by the suction pad 31D. The portion of the third original roll RS3 including the lead end RS3T cut off by the cutting blade 31G is removed by the user or by the conveying means (not shown).

Next, the first attachment means 10 and the supply means 40 drive the linear motor 11A and the linear motor 49 to pass the support plate 11C under the original roll guide plate 11H and return it to the initial position. At this time, the connection means 30 drives the articulated robot 31H to guide the pulled-out third original roll RS3 so that it does not get caught on the original roll guide plate 11H, etc. When the support plate 11C returns to the initial position, the connection means 30 drives the articulated robot 31H to move the chuck arm 31M holding the third original roll RS3 into the connection notch 11F as shown in FIG. 2(C), bringing the cutting reference edge 31N into close contact with the connection reference position 11E, and butting and positioning the connection rear end RS1R of the first original roll RS1 and the connection front end RS3F of the third original roll RS3. Thereafter, the connecting means 30 drives the rotating motor 32K and the pressure reducing means (not shown), pays out the fourth original roll RS4, and the leading connecting tape CT is peeled off at the peeling edge 32D of the peeling plate 32C. When the leading end of the next connecting tape CT following the leading connecting tape CT in the payout direction reaches a predetermined position near the peeling edge 32D of the peeling plate 32C, the driving of the rotating 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, and as shown by the two-dot chain lines in Figs. 2(C) and (D), the connecting tape CT is pressed against the first release sheet RL1 and the third release sheet RL3 to be affixed, and then the driving of the pressure reducing means (not shown) is stopped to return the holding member 32J to its initial position, and the connecting means 30 drives the articulated robot 31H and the linear motor 31K to return the pair of chuck arms 31M to their initial positions. This connects the third original roll RS3 to the first original roll RS1 using the connection tape CT, and the third original roll RS3 connected to the first original roll RS1 becomes the first original roll RS1, and the associated third support plate RS3B and third support tube RS3P become the first support plate RS1B and first support tube RS1P.

After this, the second bonding means 20 continues to bond the second adhesive sheet AS2, and when the final end RS2E of the second original roll RS2 comes off the second support tube RS2P and the final end RS2E is detected by the final end detector 27, the bonding operation by the first bonding means 10 is started and then the bonding operation by the second bonding means 20 is stopped. With this switching, the adherend WK to which the first adhesive sheet AS1 is bonded by the first bonding means 10 is identified by the above-mentioned determination by the control device 53, so that the control device 53 outputs a drive stop signal to the second bonding means 20 for the adherend WK identified as having the first adhesive sheet AS1 bonded thereto, and the second bonding means 20 does not bond the second adhesive sheet AS2. This prevents the first adhesive sheet AS1 or the second adhesive sheet AS2 from being left unbonded or being bonded in duplicate to the adherend WK.
The operation of connecting the connection tip end RS3F of the third original roll RS3 to the connection rear end end RS2R of the second original roll RS2 is the same as the operation of connecting the connection tip end RS3F of the third original roll RS3 to the connection rear end end RS1R of the first original roll RS1, except that, as shown by the dotted line in Figure 2 (D), the holding member 32J that adsorbs and holds the connection tape CT descends once, passes under the original roll guide plate 11H, and then rises again to attach the connection tape CT it is holding to the second release sheet RL1 and the third release sheet RL3. Therefore, a description of this operation will be omitted.

According to the embodiment described above, a single supply means 40 capable of supplying the third original roll RS3 to both the first attachment means 10 and the second attachment means 10 is provided, which prevents the device from becoming too large.
