After gripping, the gripping means is moved horizontally by the gripping means transfer device to draw out the resin sheet, the drawn resin sheet is cut at a predetermined position by the resin sheet cutting device, and the cut resin sheet is supported by the supporting member. In addition, there is a structure in which both end portions of the resin sheet on the support member are pushed down by a holding mechanism.

[0003]

However, in the conventional resin sheet cutting device having such a structure, since the drawn resin sheet is biased in the width direction, the resin sheet is formed so as to be perpendicular to the edge of the resin sheet. There is a problem that the sheet cannot be cut, and furthermore, there is a problem that the resin sheet is sent to the molding station as defective and is molded. The present invention has been made in order to solve the above problems, and cuts a resin sheet to be pulled out so as to be substantially perpendicular to this edge, and prevents a defective resin sheet from being fed to a molding station. The purpose is to provide equipment.

[0004]

Means for Solving the Problems To achieve the above object, a resin sheet cutting facility of the present invention is a resin sheet cutting facility for drawing a resin sheet from a resin sheet roll and cutting it into a predetermined length.

A one-shot stocker mechanism that temporarily holds the resin sheet and applies an appropriate amount of tension to the resin sheet, a gripping means that can grip the tip of the resin sheet from the one-shot stocker mechanism, and move the gripping means in the horizontal direction. A gripping means transfer device for drawing out a resin sheet from the one-shot stocker mechanism, and the one-shot stocker mechanism Measuring means for measuring the length of the resin sheet pulled out from the one-shot stocker mechanism, a resin sheet cutting device for cutting the resin sheet pulled out from the one-shot stocker mechanism at a predetermined position, and the resin sheet pulled out from the one-shot stocker mechanism. A bias correction device that corrects a bias in the width direction of the resin sheet in the vicinity of the resin sheet cutting device, and a detection unit that detects a mark for indicating the quality of the drawn resin sheet are provided.

[0005]

In the equipment constructed as described above, the resin sheet previously fed from the resin sheet roll set in the resin sheet roll rotating device is passed through the one-shot stocker mechanism and then the leading end is grasped by the grasping means. Then, while the length of the pulling-out means is measured by the measuring means, it is pulled out by the movement of the gripping means by the gripping means transfer device. The drawn-out resin sheet corrects the deviation in the width direction of the resin sheet near the resin sheet cutting device by the deviation correction means, and then the resin sheet drawn out by a predetermined length is cut at a predetermined position by the resin sheet cutting device. The Rukoto. Then, when a defect of the resin sheet is found by the detecting means, the resin sheet having a predetermined length plus the defective portion is cut and removed.
