Description

  The present invention relates to a method and an apparatus for peeling a laminate laminated on the surface of a sheet material, and more specifically, peeling off the laminate with an adhesive roller after peeling off the leading end of the laminate in a pretreatment step In addition, the present invention relates to a laminate peeling method and apparatus in which the peeled laminate is separated from the adhesive roller and stored.

  Conventionally, a method of peeling a laminate laminated on various sheet materials such as a polarizing plate from the sheet material has been proposed.

For example, an adhesive tape is applied to a laminate laminated on a sheet material, and the adhesive tape is wound together with the laminate, or the adhesive roller is pressed against the laminate and the adhesive roller is rotated, and the laminate is wound around the outer periphery of the adhesive roller. The method etc. are performed (for example, refer patent document 1).
JP-A-5-273508

  However, at the start of peeling of the laminate with the adhesive tape or adhesive roller, the laminate and the sheet material do not peel off well, so that the peeling may fail or the sheet material may be caught in the adhesive tape or the adhesive roller. This problem became more prominent when the size was increased.

  In the peeling method using the adhesive tape, when the unnecessary laminate is discarded, the entire adhesive tape must be replaced, and the operation is interrupted at the time of replacement, resulting in a decrease in work efficiency.

  When a laminate or the like to be peeled is formed on both surfaces of the sheet material, two peeling mechanisms are required, or a sheet material reversing mechanism is necessary to perform the peeling mechanism in one machine, It takes time because it must be peeled off one by one.

  In addition, the method of winding with an adhesive roller has a problem that the winding diameter increases according to the laminated laminate and the pressing force of the adhesive roller changes to prevent stable peeling.

  Furthermore, since the adhesive surface is not exposed until the laminate is discharged from the adhesive roller, multiple laminates cannot be peeled as they are, and when disposing of the laminated laminate, a separate peeling device is prepared and wound. There is a problem that it takes time to work because the laminated laminate that has been taken out is discarded while being unwound.

  Accordingly, the problem of the present invention is that there is no failure in peeling the laminate with the adhesive roller, and the laminate can be peeled off continuously, so that the work efficiency can be improved and the laminate to be peeled off on both sides. It is an object of the present invention to provide a laminate peeling method and apparatus which can be peeled at the same time even when the above are formed.

  In order to solve the above-mentioned problems, the invention of claim 1 is a peeling method for peeling a laminate from a sheet material, and an adhesive roll is brought into contact with the peeling leading end portion of the laminate before starting to peel the laminate from the sheet material. The sheet material is run in the width direction of the sheet material, and the front end of the laminate is peeled off to give a trigger for separation, and the sheet material processed in the pretreatment step is opposed to at least one using an adhesive roller. A configuration is adopted in which a peeling process is performed in which the laminate is supplied from the leading end portion of the laminate which gives a trigger for peeling between the arranged rollers, and the laminate is peeled off from the sheet material by the adhesive roller.

  Invention of Claim 2 employ | adopted the structure which added the isolation | separation process which isolate | separates a laminate from an adhesive roller by the separation nail | claw arrange | positioned in the part of an adhesive roller immediately after the peeling process in the invention of the said Claim 1. Is.

  The invention according to claim 3 is a sheet material storage portion that stores the sheet material in a stack, and a sheet material take-out mechanism that is located above the sheet material storage portion, takes out the sheet material from the sheet material storage portion, and sends it forward. A sheet material feeding mechanism that forwards the sheet material received from the sheet material take-out mechanism, and a sheet material that is positioned in front of the sheet material feeding mechanism and is sent to stop at a fixed position by the sheet material feeding mechanism. On the other hand, a pretreatment mechanism that runs in the width direction of the sheet material in a state where the adhesive roll is in contact with the peeling leading end of the laminate, peels off the leading end of the laminate and gives a trigger for peeling, and is positioned in front of the preprocessing mechanism. Then, when the sheet material is supplied from the leading edge of the laminate given the trigger for peeling between the rollers arranged in an opposing manner using an adhesive roller on at least one side, In wearing the roller is obtained by adopting the configuration that is formed by a sheet material and a release mechanism for peeling the laminate.

  The invention of claim 4 employs a configuration in which, in the invention of claim 3 above, a separation claw for separating the laminate from the adhesive roller is disposed in the adhesive roller portion of the peeling mechanism.

  Here, by using both of the rollers used in the peeling step as adhesive rollers, both sides of the sheet material can be peeled off simultaneously when a laminate or the like to be peeled is formed.

  According to the present invention, before starting the peeling of the sheet material, it is run in the width direction of the sheet material in a state where the adhesive roll is in contact with the peeling leading end portion of the laminate, and before the peeling tip is given off by peeling off the leading end portion of the laminate. After applying the treatment process, the laminate was peeled off from the sheet material with the adhesive roller, so that the laminate was peeled off with the adhesive roller in the peeling process because the leading edge of the laminate was peeled off in the pretreatment process. By eliminating the failure of peeling, the adhesive roller does not entrain the sheet material, and damage to the sheet material can be prevented.

  In addition, the laminate is peeled off from the sheet material by the adhesive roller in the peeling process, and the laminate is separated from the adhesive roller by the separation claw disposed in the adhesive roller portion, so that the peeling of the laminate can be performed without the need to replace the adhesive roller. Can be performed continuously, and there is no interruption, so work efficiency can be improved.

  Furthermore, by using both adhesive rollers as the rollers used in the peeling process, when a laminate to be peeled is formed on both sides of the sheet material, both sides can be peeled off simultaneously with a single peeling device. It is possible to reduce the cost, simplify the apparatus, and improve the peeling efficiency.

  Further, since the laminate separated from the adhesive roller by the separation claw is transported to the take-out side end portion by the transport belt and the laminate is stored or discarded in the laminate storage portion, the peeled laminate can be easily processed.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.
