[0002]

2. Description of the Related Art Most commonly, food wrap sheets are sold in rolls and stored in paper cases. That is, the roll of the wrap sheet is housed in the case, and when used, the seal of the integral lid portion of the paper case is opened, and the required length of the wrap sheet is pulled out by grasping the tip of the wrap by opening the lid. The wrap sheet was cut by a metal, plastic or paper saw blade provided along the case lid.

[0003] Conventional paper cases are premised on being disposable, and when the roll of the wrap sheet runs out, the paper case is discarded. Therefore, there is a problem that the cost of the case is added to the cost of the wrap sheet. Further, as a case, even if it is still usable, it has to be discarded, which is not preferable from the viewpoint of resource saving.

[0004] Japanese Patent Application Laid-Open No. 2000-62842 discloses a sheet roll packaged article formed by wrapping a long sheet wound up in a roll form in a roll form from the outer periphery in a paper wrapping band. The inner end side of the paper wrapping band is adhered to the winding end of the outermost layer portion of the wrap sheet with an adhesive tape, and the wrapping band is wound on a wrap sheet roll, and both sides of the wrapping band connected by ribbon tape. The wrap sheet package is completed by folding the folded part and attaching and closing the folded ends of the wrapping band with a disk-shaped sheet. At the time of use (at the time of replacement when the wrap sheet is exhausted), the ribbon tape is pulled to separate both ends of the wrapping band, and the tab at the front end of the wrapping band is pulled out to draw out the wrap sheet from the roll. In a case.

Is arranged.

Next, a series of procedures (a) to (b) in FIGS.
The method of manufacturing the wrap sheet roll of the present invention according to (h) will be described step by step. In FIG. 1 (a), the peripheral surface of the winding drum 10 is located on the upstream side (left side in the figure) which is not shown. A wrap sheet R such as a polyethylene film from a raw roll is engaged, and the rotary drum 10 is rotated by a rotary drive motor.
The wrap sheet is wound into a roll 13 around the winding shaft 12 (in an expanded state as shown in FIG. 5A) that comes into contact with the wrap sheet. When the wrap sheet roll 13 reaches a predetermined winding diameter,
The drum 10 is stopped.

When the holding state of the winding shaft 12 is released at both ends, the winding shaft 12 rolls together with the wrap sheet roll 13 wound thereon as shown by an arrow a, and finally rolls. 13 reaches the state shown in FIG. 1B seated on the pair of support rollers 20. At this time, the roll is still connected to the web, and the wrap sheet R extends from the roll via the winding drum 10 to the web.

Next, FIG. 2C shows a state in which the pressure roller 22 descends as indicated by an arrow b and abuts against the lap sheet roll 13 seated on the support roller 20 with an appropriate pressing force. In this state, the pressure roller 22 is slightly rotated in the direction of arrow c, and accordingly the wrap sheet roll 13 is slightly rotated in the winding direction as shown by arrow d. Is somewhat strained to extend in the tangential direction.

FIG. 2D shows the next stage, in which the cutter assembly 16 is lowered as indicated by the arrow e, and the wrap sheet holder 16A presses the extended portion of the wrap sheet R against the chute 14. Then, the cutter blade 16B is lowered,
The lap sheet R is cut to pass through the slit 14-1 of the chute 14. In the figure, R 'indicates the remaining extension of the wrap sheet from the roll 13 after cutting. Before and after the cutting of the wrap sheet, the feeding roller 30 is rotated as shown by the arrow f, the wrapping paper P is fed from the raw roll 32, and the leading end thereof extends from the roll 13 via the guide 24. It is engaged with the lap sheet R 'in the cross direction.

The next stage is shown by (e) in FIG. 3. The cutter assembly 16 moves up (retreats) as shown by an arrow e ', and the glue is ejected from the nozzle 26 as shown by g. Therefore, the glue is applied to one side of the wrapping paper P. The glue application area is spaced at intervals in the width direction of the wrapping paper P (in the direction perpendicular to the paper surface).
There are three places, and in (), N indicates the glue adhered.

In the next step (f), the wrapping paper cutter 28 is advanced as shown by an arrow h, and a cutting line is formed on the wrapping paper P. In this embodiment, the cutting line is perforated, and the wrapping paper P is not completely separated, but the wrapping paper P can be cut and separated along the perforation by pulling lightly.

The next stage is (g) in FIG. 4, in which the pressure roller 22 starts rotating in the direction of arrow c again. for that reason,
At the upper end of the wrapping paper P, the perforation formed by the cutter 22 is torn off and separated, while the lower end is engaged with the wrap sheet extension R ', so that the wrapping paper P moves as indicated by the arrow i. Arrow j on the roll 13 by the same portion R '
And rolled into the roll 13.

The final stage is shown by (h) in FIG.
Turns around, the wrapping paper P is adhered to the wrapping paper P because the glued portion of the glue N is opposed to the wrapping paper P, and the roll 13 of the wrap sheet R is surrounded by the wrapping paper P including the winding end portion R '. Completely enclosed, thereby completing the wrapped sheet roll package. Finally, the outer diameter of the winding shaft 12 is contracted as shown in FIG. 5 (b) by releasing air pressure from the expansion / contraction mechanism of the winding shaft 12, and the winding shaft 12 is pulled out in a direction perpendicular to the sheet of FIG. The sheet roll package is completed. In FIGS. 4 (g) and 4 (h), the winding state of the wrapping paper P and the wrap sheet R 'is exaggerated from a regular roll state to an irregular shape in order to clarify the winding state. Since the sheet has a thickness of 0.1 mm or less, it goes without saying that the sheet has a regular roll shape in an actual wound state.

In the above embodiment, the width of the wrapping paper is equal to the width of the wrap sheet R (the axial length of the roll). However, FIGS. 6 and 7 show another embodiment. The width of the paper P is larger than the width of the wrap sheet R. Also in this embodiment, the end of the wrapping paper P is engaged with the sheet extending portion R 'from the roll 13 as shown by P', and then the roll 13 is rotated as shown by the arrow, whereby the roll 13 is inserted into the roll 13. Involve the wrapping paper.

In FIG. 7A, the wrapping paper P is wound around a roll, and the wrapping paper P is adhered to the opposing surface by a glue N applied in advance by the same means as the nozzle 26 in FIG. You. Thereafter, as shown in FIG. 7C, the ear portion P1 of the wrapping paper P protruding from the roll 13 is folded into the center hole of the coreless roll 13 to complete a wrap sheet roll package. In addition, when the width of the wrapping paper P is not so large with respect to the roll axis length (wrap sheet width), the blank portion of the wrapping paper P is simply folded inward, and only partially covers the roll end surface. This variation is also included in the present invention.
