In the present embodiment, the folding angle changing means 30 is configured to change the tension applied to the peeling sheet RL folded by the peeling plate 20 based on the detection result of the tip detecting means 40. Further, the folding angle changing means 30 is in the initial stage of peeling in which the tip portion ASF in the feeding direction of the adhesive sheet AS is peeled from the peeling sheet RL during the sheet peeling operation in which one adhesive sheet AS is peeled from the peeling sheet RL.

The moving means 60 is a support table 62 supported by a linear motor 61 as a drive device and a support surface 62A supported by the slider 61A and capable of being sucked and held by a decompression means (holding means) (not shown) such as a decompression pump or a vacuum ejector. And have.

The operation of the above sheet pasting device SA will be described.
First, with respect to the sheet affixing device SA in which each member is arranged at the initial position shown by the solid line in FIG. 1, the user of the sheet affixing device SA (hereinafter, simply referred to as “user”) is folded back by the release plate 20. As the tension applied to the release sheet RL, a first tension capable of peeling the adhesive sheet AS from the release sheet RL without imposing a burden on the release sheet RL as much as possible and a second tension larger than the first tension are used. Input is performed via an operation means (not shown) such as an operation panel or a personal computer. Next, after the user sets the raw fabric RS as shown in the figure, when a signal for starting operation is input via an operating means (not shown), the feeding means 10 and the turning angle changing means 30 rotate the rotary motors 13A and 14A. The original fabric RS is fed while applying the first tension to the release sheet RL that is driven and folded back by the release plate 20. Then, as shown in FIG. 1 (B), the leaf spring 32B is bent by a predetermined amount, and the folding angle θ folded back by the release plate 20 becomes the first folding angle θ1, and the original fabric RS is maintained while the first folding angle θ1 is maintained. When the raw fabric stop sensor 16 detects a step behind the seat, the feeding means 10 and the folding angle changing means 30 stop driving the rotation motors 13A and 14A, and the feeding of the raw fabric RS is stopped. In this embodiment, assuming that a release sheet RL that is easily cut is adopted, the first tension applied to the release sheet RL is set so that the first folding angle θ1 is as gentle as possible. It is set.
Here, when the original fabric RS is fed out in the same manner as described above and the feeding is stopped, normally, as shown in FIG. 1A, the leading end portion ASF of the leading adhesive sheet AS in the feeding direction is the release plate 20. The peeling edge 20A is peeled off, the tip ASF in the feeding direction is detected by the tip detecting means 40, and the sheet sticking device SA is put into a standby state.

On the other hand, when the original fabric RS is fed out in the same manner as described above and the feeding is stopped, as shown in FIG. When the tip ASF in the feeding direction is not detected by the tip detecting means 40, the sheet sticking device SA (sheet supply device EA) performs the following re-peeling operation.
In this re-peeling operation, first, the feeding means 10 drives the rotation motors 13A and 14A, and the leading end portion ASF of the adhesive sheet AS in the feeding direction reaches the position before being folded back by the peeling edge 20A of the peeling plate 20. Pull back the original RS until. Next, the feeding means 10 and the folding angle changing means 30 drive the rotation motors 13A and 14A to apply a second tension to the peeling sheet RL folded back by the peeling plate 20, and as shown in FIG. 1C, the second tension is applied. The leaf spring 32B is flexed more than when the leaf spring 32B is flexed by one tension, and the peeling sheet RL is folded back with the folding angle θ as the second folding angle θ2 smaller than the first folding angle θ1, and the second folding angle. The original fabric RS is delivered while maintaining θ2. As a result, a large tension is applied to the release sheet RL, and the folding angle θ of the release sheet RL is reduced, so that the adhesive sheet AS can be easily peeled off from the release sheet RL, and the original fabric RS is as described above. When the feeding is stopped, the tip ASF of the leading adhesive sheet AS in the feeding direction is peeled off by the peeling edge 20A of the peeling plate 20 as shown in FIG. 1 (C). Then, when the tip ASF in the feeding direction is detected by the tip detecting means 40, the folding angle changing means 30 drives the rotation motors 13A and 14A, and the peeling sheet RL is pulled out from the recovery roller 15 side while being pulled out by the peeling plate 20. After applying the first tension to the peeling sheet RL to be folded and setting the folding angle θ of the peeling sheet RL to the first folding angle θ1, the sheet attaching device SA is put into the standby state.

After the sheet sticking device SA is in the standby state, when the user or a transporting means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the support table 62, the moving means 60 reduces the pressure (not shown). It drives the means and starts adsorbing and holding the adherend WK on the support surface 62A. After that, the moving means 60 drives the linear motor 61 to move the support table 62 to the left, and when the adherend WK reaches a predetermined position, the feeding means 10 and the turning angle changing means 30 move the rotating motor 13A, 14A is driven, and the original fabric RS is delivered according to the moving speed of the adherend WK. At this time, the feeding means 10 and the folding angle changing means 30 apply a first tension to the peeling sheet RL folded by the peeling plate 20 so that the folding angle θ folded by the peeling plate 20 maintains the first folding angle θ1. While doing so, the original anti-RS is delivered. As a result, the adhesive sheet AS is pressed from the release sheet RL by the release edge 20A of the release plate 20 and pressed against the upper surface of the adherend WK by the pressing roller 50, as shown by the alternate long and short dash line in FIG. 1 (A). And pasted. At this time, since the adhesive sheet AS can be peeled from the peeling sheet RL without imposing a burden on the peeling sheet RL as much as possible, it is possible to prevent the peeling sheet RL from being cut.

After the entire adhesive sheet AS is attached to the adherend WK, when the original fabric stop sensor 16 detects the step behind the sheet again, the feeding means 10 and the folding angle changing means 30 stop driving the rotation motors 13A and 14A. , Stop the feeding of the original fabric RS. Also at this time, if the feeding direction tip ASF is not detected by the tip detecting means 40, the feeding means 10 and the folding angle changing means 30 perform the above-mentioned re-peeling operation, and the feeding direction tip ASF becomes the tip detecting means 40. When it is detected, the sheet sticking device SA goes into the standby state again.

Next, when the adherend WK to which the entire adhesive sheet AS is attached reaches a predetermined position on the left side of the pressing roller 50, the moving means 60 stops driving the linear motor 61 and the decompression means (not shown). Then, after the user or the conveying means (not shown) conveys the adherend WK to which the adhesive sheet AS is attached to the next step, the moving means 60 drives the linear motor 61 and returns the support table 62 to the initial position. After that, the same operation as described above is repeated.

According to the above embodiment, by changing the tension applied to the release sheet RL, the folding angle θ of the release sheet is changed, so that it is possible to suppress the device from becoming large and adhere to the release sheet RL. The sheet AS can be reliably peeled off and supplied.

The means and processes in the present invention are not limited as long as they can perform the operations, functions or processes described for the means and processes, much less the constituents of the mere embodiment shown in the above-described embodiment. It is not limited to the process at all. For example, the feeding means is limited as long as it is possible to feed the original fabric with the adhesive sheet temporarily attached to the release sheet, as long as it is within the technical range in light of the common general technical knowledge at the time of filing. Nothing (same for other means and processes).

For example, the feeding means 10 has a band-shaped adhesive sheet base material temporarily attached to the release sheet RL by forming a closed loop-shaped or short cut in the entire width direction, so that a predetermined region partitioned by the cut is formed. May feed out the raw fabric RS as the adhesive sheet AS, or when the raw fabric RS in which the strip-shaped adhesive sheet base material is temporarily attached to the release sheet RL is adopted, the adhesive sheet base material is used by a cutting means. A closed loop-shaped or short cut in the entire width direction may be formed, and a predetermined area partitioned by the cut may be used as an adhesive sheet AS. In these cases, the original fabric stop sensor 16 can detect a step behind the sheet. In addition, a removing means for removing the portion of the adhesive sheet base material other than the adhesive sheet AS from the release sheet RL may be adopted in front of the detection unit 16A, or the cut may be detected even if there is no step behind the sheet. A suitable sensor may be provided.
The feeding means 10 may support or guide the raw fabric RS or the release sheet RL with a plate-shaped member, a shaft member, or the like instead of the rollers such as the support roller 11 and the guide roller 12, or the raw fabric RS. It may be supported by folding it in a fan fold without winding it, or by adopting an imaging means such as a camera or a projector, or various sensors such as an optical sensor or an ultrasonic sensor, as the original fabric stop sensor. Alternatively, the release sheet RL may be collected by folding it into a fan fold without winding it, or by chopping it with a shredder or the like, or it may not be necessary to collect the release sheet RL. The sheet rear step of the sheet AS may be detected by the detection unit 16A, or the sheet front step between the leading end portion ASF in the feeding direction other than the leading adhesive sheet AS and the release sheet RL may be detected by the detection unit 16A. However, the sheet step at another position may be detected by the detection unit 16A.

The folding angle changing means 30 does not have to change the folding angle θ between the initial peeling stage and another stage, and the folding angle θ at the initial peeling stage is larger than the folding angle θ at the other stages. When the tip ASF in the feeding direction of the adhesive sheet AS is not detected by the tip detecting means 40, the rotation motor 14A is driven without pulling back the original RS, and the adhesive sheet AS is folded back by the release plate 20. A re-peeling operation without re-feeding may be performed a predetermined number of times (once or a plurality of times) by applying a tension larger than the tension previously applied to the peel-off sheet RL and reducing the folding angle θ.

A configuration may be adopted in which tension is applied to the release sheet RL folded back by the release plate 20 by pushing up or down the sheet RL, or the tension applied to the release sheet RL folded back by the release plate 20 is changed. By doing so, any configuration may be used as long as the folding angle θ can be changed.
As shown in FIG. 2A, the folding angle changing means 30 is configured as a folding posture forming member 32 by a roller 32D rotatably supported by a spring 32C as an urging means, and is folded by a release plate 20. By changing the tension applied to the release sheet RL, the spring 32C may be expanded and contracted, and a folding angle θ may be changed. As shown in FIG. 2B, a predetermined air pressure or torque may be used. A release sheet that is composed of an urging means 32E such as an air cylinder or a linear motion motor that applies an urging force to the output shaft 32F, and a roller 32G that is rotatably supported by the output shaft 32F, and is folded back by the release plate 20. By changing the tension applied to the RL, the output shaft 32F may be recessed and the folding angle θ may be changed, or as shown in FIG. 2C, the output shaft 32F may be retracted with a predetermined torque. It is composed of an urging means 32H such as a rotating motor that applies an urging force to the output shaft 32J and a blade member 32K rotatably supported by the output shaft 32J, and is applied to the release sheet RL folded back by the release plate 20. By changing the tension, the blade member 32K may be rotated and the folding angle θ may be changed, or as shown in FIG. 2D, the notch 20B formed in the release plate 20 may be adopted. A peeling sheet RL composed of a rotary blade member 32M rotatably supported inside via a support shaft 32L and urged in a counterclockwise rotation direction by a spring (not shown) as a urging means, and folded back by a peeling plate 20. By changing the tension applied, a spring (not shown) may be expanded and contracted, and a folding angle θ may be changed. By changing the tension applied to the release sheet RL folded by the release plate 20, the tension applied to the release sheet RL may be changed. Any configuration may be used as long as the folding angle θ can be changed.

The tip detecting means 40 may employ various contact-type sensors that are in contact with the feeding direction tip ASF of the adhesive sheet AS and can detect that the feeding direction tip ASF is peeled from the peeling sheet RL. The sheet supply device EA and the sheet sticking device SA of the present invention may not be provided, and if the tip detecting means 40 is not provided in the sheet supply device EA or the sheet sticking device SA of the present invention, the release plate 20 is newly used. At the timing when the tip ASF of the adhesive sheet AS in the feeding direction is peeled from the peeling sheet RL, the above-mentioned re-peeling operation or the re-peeling operation without re-feeding may be performed a predetermined time (once or a plurality of times). ..

The pressing means may also be configured to include a drive device in which the adhesive sheet AS supplied from the sheet supply device EA is held by a holding member from the opposite side of the adhesive surface, and the held adhesive sheet AS is pressed against the adherend WK and attached. Alternatively, a drive device as a pressing member contacting / detaching means for bringing the pressing roller 50 away from and approaching the adherend WK may be provided to prevent the adherend WK from being stressed or damaged. As such a pressing member contacting / detaching means, the pressing roller 50 may be manually moved in addition to the driving device.

One or more may be set, and various tensions may be applied each time the re-peeling operation is repeated, and the peeling sheet RL may be folded back by the peeling plate 20 at various folding angles θ. The tension applied to the peeling sheet RL folded back by the plate 20 may be constant, and the peeling sheet RL may be folded back a plurality of times by the peeling plate 20 at a constant folding angle θ, or even if the peeling operation is performed a predetermined number of times, the tip is detected. When the means 40 does not detect the tip ASF in the feeding direction, after stopping the driving of the rotary motors 13A and 14A, a warning means (not shown) such as a lamp or a buzzer is driven to notify the user, and the user is notified. The tip ASF in the feeding direction may be peeled off from the peeling sheet RL, or the tension applied to the peeling sheet RL folded back by the peeling plate 20 each time the re-peeling operation is repeated is higher than the tension applied earlier. The folding angle θ may be decreased or increased by increasing or decreasing it, or the tension applied to the peeling sheet RL folded by the peeling plate 20 is randomly reduced each time the re-peeling operation is repeated. The folding angle θ may be randomly decreased or increased by increasing or decreasing, or the re-peeling operation or the re-peeling operation without re-feeding may not be performed, and the peeling sheet RL, adhesion may be performed. The user is folded back by the release plate 20 in consideration of the characteristics, characteristics, properties, materials, composition, composition, shape, dimensions and weight of the sheet AS or the raw fabric RS, the atmospheric conditions, and other factors. The tension applied to the peeling sheet RL and the folding angle θ of the peeling sheet RL may be arbitrarily set. For example, the folding angle θ (folding angle set to θ1, θ2 or others) is 179 degrees, 90 degrees, 45. The tension applied to the release sheet RL folded back by the release plate 20 may be set so as to be degrees, 10 degrees, 1 degree, 1 degree or less, or any combination of the first tension and the second tension.
