Problems solved by technology

However, since the take-up shaft is rotated in the opposite direction in order to increase the size of the take-up portion, it is necessary to use a reversible motor for the drive motor of the take-up shaft or provide a clutch mechanism that can change the direction of rotation. The mechanism that transmits the rotation of the motor to the take-up shaft is changed according to the transmission path, and the structure may become complicated
Moreover, when forming an enlarged take-up portion, it is necessary to rotate at a speed much lower than that at the time of forming a film roll, so the rotation control of the driving motor becomes complicated.
In addition, when a paper tube is used for the winding shaft, there is a possibility that the end of the paper tube may be damaged or broken due to a change in the direction of rotation.

Embodiment Construction

[0041] Next, according to the preferred embodiment shown in the drawings, the tail processing device of the resin film roll according to the present invention will be described, together with the tail processing method of the resin film roll and the tail processing device formed by the processing method. Resin film rolls and the resin film roll products.

[0042] Figure 4 It is a figure which shows the outline|summary of the manufacturing apparatus 1 of the resin-made film roll suitably equipped with the tail processing apparatus 10 of the resin-made film roll which concerns on this invention. The film sheet to be produced is wound up and supplied to a winding device, cut into the width at the time of shipment, wound up, processed into a raw material roll P, and supplied to the manufacturing device 1 . In addition, in order to provide for the manufacture of the next film roll, prepare the raw material roll P 1 standby.

[0043] The film sheet unwound from the raw material ...

Abstract

The trailing end-processing device (10) comprises a turret plate (3a), a film roll rotation roller (11), and a trailing end-contacting plate (12a). Just prior to completion of winding of a film sheet (S) on a paper tube (4) at a roll formation position (42), the turret plate (3a) transfers the film roll (R) to the trailing end-processing position (43). In the process thereof, the roll (R) is severed from the succeeding sheet (S) and a trailing end is formed on the roll (R). At the processing position (43), the roller (11) contacts the roll (R) by the pivoting of a pivot arm (11b) to stop the rotation of the roll (R). Moreover, the plate (12a) contacts the roll (R) by the forward movement of a piston rod (13a). When the roller (11) then rotates the roll (R) in the unwinding direction, the plate (12a) prevents the movement of the unwound trailing end and the trailing end is rounded and forms a rolled grip (20).

Description

technical field [0001] This invention relates to a resin film roll tail processing device for easily unwinding the film roll by processing the winding end of a film roll on which a resin film sheet is wound, that is, the tail, and A tailing treatment method, a resin film roll provided with a tail formed by the treatment method, and the resin film roll product. Background technique [0002] For example, a sheet of plastic film for food packaging is provided as a roll-up film roll. This film for food packaging is extremely thin, with a thickness of 5 to 20 μm, colorless and transparent, so that the inside can be visually recognized in the state of covering the food, and in order to seal the food inside, it has adhesiveness so that it can be combined with the food containing the food. Trays and dishes stick together. For this reason, when the film roll is used, even if it is intended to be unwound or to be peeled off from the end of the roll, it may not be easily peeled off. ...
