However, in an apparatus like patent document 1, the peeling board which has a big width | variety is employ | adopted in many cases in order to respond | correspond to the original fabric of various width sizes. For this reason, as shown in FIG. 5, the protruding width H from the side edge of the adhesive sheet S to the side edge of the peeling plate P is increased. As a result, when the adhesive sheet S is affixed to the side surface W1 of the adherend W, the peeling plate P becomes an obstacle, and the adhering position of the adhesive sheet S cannot be brought close to the lower side of the adherend W. There is an inconvenience of being restricted.
Here, it is conceivable that a notch is provided on the lower tip side of the peeling plate P to bring the sticking position closer to the lowermost part of the adherend W. Inconvenience that the performance is reduced.

  By the way, in an apparatus like patent document 1, since the peeling characteristic of an adhesive sheet improves when the peeling sheet is folded back rapidly, the peeling area of the peeling plate is formed thinly or sharply. In this way, the peeling failure at the peeling plate is suppressed. However, when the tip of the release plate is formed thinly or sharply in this way, if the release sheet is made of thin paper or a thin resin sheet, the release sheet is cut by rubbing against the tip of the release plate. There is an inconvenience that it becomes easy to cause a sticking failure of the adhesive sheet.

[Object of invention]
An object of the present invention is to provide a sheet feeding device and a feeding method, a sheet sticking device, and a sticking method that can deal with originals of various width sizes and can increase the degree of freedom of the sticking position of an adhesive sheet.
Another object of the present invention is to provide a sheet feeding device and a feeding method, and a sheet pasting device and a pasting method capable of suppressing the peeling failure of the adhesive sheet due to the shape of the peeling plate and the poor pasting of the adhesive sheet. There is to do.

  In order to achieve the above object, the present invention provides a feeding means for feeding out an original fabric in which an adhesive sheet is temporarily attached to a strip-shaped release sheet, and folding back the release sheet in the course of feeding out the original fabric to remove the adhesive sheet from the release sheet. A configuration is adopted in which a peeling unit that peels off and a displacement unit that relatively moves the feeding unit and the peeling unit in a direction crossing the feeding direction of the original fabric.

  In the present invention, it is preferable that the peeling means includes a peeling plate that folds the peeling sheet at the tip, and the peeling plate has a plurality of folding regions having different thicknesses at the tip.

Further, the supply method of the present invention is a sheet supply method for supplying an adhesive sheet from an original fabric in which the adhesive sheet is temporarily attached to a strip-shaped release sheet.
A step of feeding the original fabric by a feeding means;
A step of folding the rolled-out original peel sheet with a peeling means and peeling the adhesive sheet;
A method is adopted in which a step of moving the feeding means and the peeling means relative to each other in a direction crossing the feeding direction of the original fabric before or during the feeding of the original fabric is employed.

  Furthermore, the sheet sticking device of the present invention comprises the sheet feeding device according to claim 1 or 2 and pressing means for pressing and sticking the adhesive sheet supplied from the sheet feeding device to the adherend. Is adopted.

Further, the sticking method of the present invention is a sheet sticking method for sticking an adhesive sheet of an original fabric in which an adhesive sheet is temporarily attached to a strip-shaped release sheet to an adherend,
A step of feeding the original fabric by a feeding means;

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3, the sheet sticking device 10 includes a sheet feeding device 11 and a pressing unit 13 that presses and sticks the adhesive sheet S supplied from the sheet feeding device 11 to the adherend W. Has been. The pressing means 13 is composed of a press roller, and can be applied to the adherend W by applying a pressing force to the adhesive sheet S.

  The sheet supply apparatus 11 includes a feeding unit 15 that feeds a strip-shaped original fabric R in which an adhesive sheet S is temporarily attached to a strip-shaped release sheet RL, and folds the release sheet RL in the middle of feeding the original fabric R to return the release sheet RL A peeling means 16 for peeling the adhesive sheet S and a displacement means 17 for moving the peeling means 16 are provided, and the adhesive sheet S can be supplied toward the pressing means 13.

  The feeding means 15 is supported by a frame F fixedly arranged above the conveying means CV via a stand (not shown). The feeding means 15 supports the original fabric R, and includes a support shaft 21 that can be rotated by the motor M1, guide rollers 22 and 23 around which the original fabric R is wound, and a release sheet RL after passing through the release means 16. A driving roller 25 that is wound around and is rotatably provided by the motor M2, a pinch roller 26 that sandwiches the release sheet RL between the drive roller 25, and a winding that winds the release sheet RL with a predetermined torque by the motor M3. A take-up shaft 27 is provided. Each of the motors M1 to M3 can adjust the rotation direction, the rotation speed, and the tension of the release sheet RL.

  The peeling means 16 includes a peeling plate 29 made of a metal plate or the like capable of folding the peeling sheet RL at the tip. The peeling plate 29 has a plurality of folded regions with different thicknesses at the tip. Specifically, as shown in FIGS. 2 and 3, the sharp region A1 (the region where the folded edge is thin) provided with a sharp shape in the folded region is duller than the sharp region A1. A non-sharp region A3 (a region where the folded edge is thick) provided in the shape, and an intermediate region A2 is provided between the sharp region A1 and the non-sharp region A3. In the present embodiment, the release plate 29 is made of a stainless steel plate having a thickness of 3 mm, and the sharp region A1 is ground so that the release plate 29 has a tapered shape with a tip thickness of 0.5 mm, and the tip has a radius of 0.25 mm. Arc-shaped chamfering is applied. In addition, the non-sharp area A3 has an arc-shaped chamfer with a radius of 1.5 mm at its tip without being tapered, in order to dull the sharpness of the non-sharp area A3. The intermediate region A2 is ground so that the sharp region A1 and the non-sharp region A3 are connected by a slope-like gentle inclined surface.

  The displacement means 17 is composed of a linear motion motor 18 supported by the frame F via the bracket B. Then, the peeling plate 29 is fixed to the slider 18A of the linear motor 18 so that the peeling plate 29 can move in the direction crossing the feeding direction of the original fabric R, that is, the vertical direction in FIG.

  Next, the overall operation of this embodiment will be described.

  As an initial operation, the original fabric R supported by the support shaft 21 is pulled out by a predetermined length, and as shown in FIG. The original fabric R is passed between the pinch roller 26 and the lead end of the original fabric R is fixed to the winding shaft 27.

When an operation signal is input from an operation panel or the like (not shown), the displacement means 17 operates to move the peeling plate 29 downward in the drawing as shown in FIG. Then, the motors M1 to M3 are driven to feed out the original fabric R, and the leading end side (initial peeling area) of the adhesive sheet S is partially peeled from the peeling sheet RL in the sharp area A1 of the peeling plate 29, and a sensor (not shown) Thus, the leading edge of the adhesive sheet S is detected, and the feeding of the original fabric R is stopped. Next, as shown in FIG. 2 (A), the displacing means 17 is operated to move the peeling plate 29 upward in FIG. As described above, the adhesive sheet S is peeled off from the release sheet RL, and the initial release area of the adhesive sheet S is peeled off at the sharp area A1, so that the adhesive sheet S can be partly peeled and the peeling failure is prevented. can do.
Thereafter, the adherend W is transported leftward in FIG. 1 by the transport means CV, and the motors M1 to M3 are activated when it is detected by a sensor (not shown) that the adherend has reached the application position of the adhesive sheet S. Then, the raw fabric R is fed out at the same speed as the conveyance speed of the adherend W. By feeding the original fabric R, the adhesive sheet S is peeled from the release sheet RL in the non-sharp area A3 of the release plate 29. Then, the peeled adhesive sheet S is supplied between the adherend W and the pressing means 13, pressed by the pressing means 13, and attached to the upper surface of the adherend W. In this way, by peeling off the region other than the initial release region of the adhesive sheet S in the non-sharp region A3, the release sheet RL is rubbed and cut by the sharp tip, resulting in a defective sticking of the adhesive sheet S. Can be resolved.

  When the application of the adhesive sheet S is completed, the feeding of the original fabric R is stopped again, and then the displacement means 17 is operated to move the peeling plate 29 downward in FIG. 2, and the same operation as described above is repeated. .

  2A, the distance D1 between the lower end edge of the release sheet RL and the lower end edge of the release plate 29 is set to 0, or the upper end edge of the release sheet RL and the upper end edge of the release plate 29 in FIG. Alternatively, the peeling plate 29 may be displaced by the displacing means 17 so that the distance D2 is zero. According to this, even if there is an obstacle or the like on the upper side or the lower side of the peeling plate 29 in the figure, the adhesive sheet S can be supplied and pasted as close as possible to the obstacle. Moreover, by adjusting the vertical position of the peeling plate 29 in FIG. 2 according to the change in the width size of the original fabric R, the width size that is the same as the horizontal width in FIG. 3 of the sharp region A1 and the non-sharp region A3 at the maximum. The versatility which makes the raw fabric R available can be provided.

Therefore, according to such an embodiment, when the adhesive sheet S is peeled off, only the initial peeled area of the adhesive sheet S, which is likely to cause a peeling failure, is peeled off in the sharp tip-shaped area A1, and other areas are sharpened. Since it peels in the non-sharp area A3 whose sharpness is duller than area | region A1, the sticking defect resulting from a release sheet being rubbed and cut | disconnected can be prevented.
Further, as shown in FIG. 3, the intermediate region A2 is formed as a slope-like gentle inclined surface so that the tip shape gradually changes between the sharp region A1 and the non-sharp region A3. When the release sheet RL and the release plate 29 are relatively moved while the release sheet RL is wound around the release sheet RL, the release sheet RL is caught by a step between the sharp region A1 and the non-sharp region A3. Further, it is possible to prevent the movement of the peeling plate 29 (up and down movement in FIG. 2) from being performed smoothly.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
In other words, the present invention has been illustrated and described mainly with respect to specific embodiments, but without departing from the scope of the technical idea and object of the present invention, the shape, position, or With respect to the arrangement and the like, those skilled in the art can make various changes as necessary.
Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

  For example, the arrangement of the sheet sticking device 10 may be changed, and the sticking position of the adhesive sheet S may be set to the side surface or the bottom surface of the adherend W.

  Further, the sheet supply device 11 is used in a device other than the sheet sticking device, for example, a sheet peeling device using the adhesive sheet S or the tip of the peeling plate 29 is directed obliquely upward as shown in FIG. In addition, the displacement means 17 may be connected to the lower surface side, and the sheet feeding device 11 may be used alone as a configuration in which the guide rollers 22 and 23 of the feeding means 15 are omitted.

The peeling means 16 can be variously modified as long as the peeling sheet RL can be folded back and the adhesive sheet S can be peeled off. The peeling means 16 can be used as a peeling roller or provided with a sharp region or a non-sharp region on the peeling plate 29. It is also possible to enlarge the width size of the original fabric R that can be dealt with, such as a release plate that does not occur. However, the tip shape of the release plate 29 as in the above-described embodiment is advantageous in that the folding mode of the release sheet RL can be easily changed.
Furthermore, the thickness and chamfering dimensions of the release plate 29 are not limited to the above embodiment, and chamfering may not be performed. In other words, when the release sheet RL is made of a material that is thin and easily cut, the release plate 29 has a thickness of more than 3 mm, or the sharp area A1 has a thickness of more than 0.5 mm. Also, when the release sheet RL is made of a material or property that is thick and difficult to cut, it is possible to prevent chamfering.
Moreover, in the said embodiment, although the folding | turning area | region of peeling sheet RL was made into 2 divisions of sharp area A1 and non-sharp area A3, you may form 3 or more divisions, for example, peeling sharp area A1 and non-sharp area A3 There is no limitation on the number of sections so that an intermediate sharp region having an arc-shaped chamfer with a tip thickness of 2 mm and a radius of 1 mm is provided.

  Furthermore, the timing at which the peeling means 16 is moved by the displacing means 17 may be during the feeding of the original fabric R.

The displacement means 17 may be replaced with driving means such as a single-axis robot, an air cylinder, or a hydraulic cylinder.
Furthermore, you may comprise the press means 13 with the gas to eject, a blade material, etc. other than a press roller.
In the above embodiment, the feeding means 15 is fixedly arranged above the conveying means CV, and the peeling plate 29 is moved by the displacing means 17. However, the peeling plate 29 is fixedly arranged above the conveying means CV and is displaced. 17, the feeding means 15 may be moved, or both the feeding means 15 and the peeling plate 29 may be moved.
Furthermore, in the said embodiment, although the peeling board 29 which has the sharp area | region A1 and the non-sharp area | region A3 was demonstrated as several folding area | regions from which thickness differs, a stainless steel board is not made into a taper shape as a folding area | region with thin thickness. A portion of this may be thinly ground.
