Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slip sheet inserting device in a steel plate winding device, and more specifically, it can automatically and safely insert a slip sheet between steel plates regardless of the winding method of any steel plate. The present invention relates to a slip sheet insertion device that can supply a slip sheet without cutting it even when the diameter of the slip sheet coil around which the slip sheet is wound becomes small.

[0002]

2. Description of the Related Art Conventionally, when stainless steel materials, surface-treated materials, and other steel plates are wound by a winding reel of a coil winder, in order to prevent deterioration of quality due to scratches caused by slip between the steel plates. A paper called interleaving paper is inserted between the steel plates.

The task of inserting the slip sheet between the steel plates is extremely difficult, and normally the operator manually inserts the slip sheet.

In addition, although it is a difficult work as described above, recently, a machine or an apparatus in which the insertion of the slip sheet is automated has been proposed, and an example thereof is disclosed in Japanese Patent Laid-Open No. 3-52712.

However, even with this device, the slip sheet cannot always be inserted safely and reliably automatically, and the assistance of the worker is required, and the slip sheet is interrupted during the line operation, which is not preferable.

That is, in the apparatus disclosed in Japanese Patent Laid-Open No. 3-52712, a strip such as a steel plate is wound on a winding reel, and when the steel plate is first wound on the winding reel, the winding reel is used. -A belt wrapper that is endlessly driven and circulated at a speed substantially equal to the peripheral speed of the winding reel is brought into contact with the outer periphery of the lower half of the reel, and the steel sheet is wound around several turns.
After that, a slip sheet hanging from above is inserted between the steel plates.

With this device, the insertion of the slip sheet can be automated, but since the slip sheet is sandwiched between the steel plates with its tip hanging down by its own weight, the place where the slip sheet is inserted faces upward. It is necessary to be open to the above, and applicable steel plate winding methods are limited to this range.

Further, in the above apparatus, it is required for the operator to assist in order to give the directionality of the slip sheet at the start of inserting the slip sheet, and the slip sheet supplied from the slip sheet coil meanders on the way. In many cases, the slip sheet cannot always be inserted safely and securely.

[0009]

As described above, when the steel sheet is wound by the coil winding machine by the method of upper winding or lower winding, the winding reel of the coil winding machine is used by using the belt wrapper.
At the same time as guiding the tip of the steel plate of the winder around the reel and winding it,
Insert a slip sheet.

However, in such a case, the conventional device,
For example, even the device described in the above publication cannot automatically insert a steel plate and thus requires the assistance of a worker.

It is also conceivable to dispose two interleaving paper rolls in order to achieve continuous insertion of interleaving paper. However, in the paper supply device in which two interleaving papers are arranged in this way, the roll diameter becomes smaller as the interleaving paper is paid out from the interleaving paper roll, and the interleaving paper is contacted with the inlet guide or the like. Has the drawback of breaking.

An object of the present invention is to solve the above-mentioned drawbacks. Specifically, two or more interleaving paper rolls can be arranged, and even if the roll diameter becomes small, the interleaving paper can be provided without breaking. We propose a slip-sheet loading device that can feed the sheet and can automatically insert a slip sheet at the start of winding regardless of the winding method.

[0013]

That is, the insertion device according to the present invention travels in the width direction of a steel plate on the upper part of a winding line for winding a steel plate sent through a pair of pinch rolls with a winding reel. A trolley to be installed, a pair of interleaf paper coils formed by wrapping a slip sheet to be inserted between the steel plates being wound on the trolley, and the trolley to be placed between the pair of interleaf paper coils. The slip-sheet is passed through downward to form a slip-sheet passage through which the slip-sheet passes downward, a tension device for tensioning the slip-sheet is provided under the slip-sheet passage, and the slip-sheet is wound under the tensioner. A guide roll for guiding in the direction of the take-up reel is arranged so as to be able to move up and down, and a cutting shear for cutting a slip sheet is provided between the tensioning device and the guide roll. Suspend the paper path, interleaf path and tension device from the trolley Characterized in that it comprises integrated Te.

More specifically, a steel plate is wound on a reel.
In order to guide the front end of the slip sheet to a position where it can be easily inserted when winding up or down the roll, a guide roll is provided at the lower part of the slip sheet passage through which the slip sheet passes downward.

Further, at the start of winding, in order to give directionality to the front end of the interleaf sheet, it is brought close to a vertically movable guide roll, and above all, an air injection hole is provided on the rear surface and blown out from this air injection hole. Directionality is given to the tip of the slip sheet by air.

Further, since the interleaf sheet roll is movably arranged in the steel sheet feed direction on the carriage, even if the diameter of the interleaf sheet roll is reduced, the interleaf sheet roll is correspondingly interleaved. Since the entrance of the passage can be approached, breakage of the slip sheet can be reliably prevented.

Further, since the carriage on which the slip sheet roll is arranged can move in the width direction of the steel sheet, the slip sheet can follow the meandering of the steel sheet.

The structure and operation of this means will be described more specifically with reference to the drawings.
