Description

Description: TECHNICAL FIELD The present invention relates to a method for shaping a roll wound material, which is obtained by cutting thin paper such as aluminum foil into a strip having a constant width and winding the thin paper into a roll. .

(Prior Art) Conventionally, in order to obtain a roll wound article as described above, a cutting roll having a cutting blade at a desired interval in the length direction while pulling out an original sheet made of a wide sheet or film. It is fed to a shaft, cut into multiple strips of tape, and then continuously wound around a core material consisting of a small-diameter paper tube or the like to form a uniform diameter. In the case of foil, when it is formed with a constant thickness by a pair of upper and lower spreading rolls, despite the fact that the crown caused by the weight of the spreading roll is corrected,
A gap error is slightly generated at both end portions, and a slight thickness change occurs in the tape body on both end sides in the width direction. When the tape body is wound, a roll formed by the tape end faces is formed. On the side surface of the winding material, a warp that is bent to one side occurs as it goes from the inner diameter to the outer diameter.

Also, in the tape body, due to subtle swings in the width direction during winding, a portion where the end surface of the tape that forms the side surface of the roll-wound material projects or is recessed, and the side surface of the roll-wound material has an uneven surface. When such warpage or unevenness occurs, not only the commercial value is lowered, but also accurate feeding cannot be performed during use.

For this reason, conventionally, the roll wound product obtained as described above is manually placed on one base plate, and a flat plate of an appropriate size is stacked on the side surface of the roll wound product facing upward. After that, the flat plate is shaped by hitting it with a hammer.

(Problems to be Solved by the Invention) However, in such a manual shaping operation, not only is the work efficiency deteriorated due to fatigue in a short time, but also a certain amount of force is applied to a certain roll wound material. There is a problem in that it may be tapped or may be tapped with an extremely weak force, and it is not possible to tap all the roll wound products with a constant force, resulting in a roll wound product with insufficient shaping.

An object of the present invention is to solve such a problem, and a method for shaping a roll-wound material which can sequentially mechanically shape the roll-wound material with a constant tapping force at regular time intervals. Is provided.

(Means for Solving the Problem) In order to achieve the above object, a method for shaping a roll wound article of the present invention is a roll wound article obtained by winding a tape body having a constant width into a desired diameter. In this state, the tape body of the roll-wound material is fed on the horizontal conveyor on a fixed table at fixed time intervals, and the press platen is shockedly dropped on the fixed table in synchronization with the feeding of the roll-wound material. It is characterized in that the winding end face of (1) is shaped flush, and after that, the press board is raised and the shaped roll-wound material is sent out.

(Operation) The roll wound material is mechanically subjected to the steps from the supply to the press processing and the delivery at regular time intervals.

During this process, after the roll material is fed onto the fixed table arranged below the press platen, the roll is wound by the flat surface facing the press platen when the press platen is dropped. Objects are shocked and pinched.

At this time, the end surface of the tape portion of the roll-wound material protruding toward the fixed base is pushed upward, while the end surface of the tape portion of the roll-wound material protruding toward the press board is moved downward by the press board. The side surface of the roll-wound material formed by the end surface of the tape that is pressed into and is wound is instantly flushed. Further, even if the side surface of the rolled material is warped, it is shaped flush with the impact pressure of the press machine in the same manner as above.
