Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to winding and unwinding of interlayer paper inserted between layers of a strip coil, and in particular to winding of interlayer paper in synchronization with the traveling speed of a metal plate. This invention relates to intermediate paper winding and unwinding machines suitable for taking up and unwinding.

[Background of the invention]

A winding machine that separates and winds the intermediate paper inserted between the layers of the strip to prevent scratches when unwinding the strip, which is a metal plate, from a coiled state, was developed in 1973. It is publicly known as described in Japanese Patent No. 219. It is also known, as described in Japanese Patent Publication No. 50-39617, to insert intermediate paper when winding a strip into a coil in order to prevent damage between the layers of the next strip. By the way, the method described in the above-mentioned Japanese Patent Publication No. 50-39617 is advantageous in automatically winding the leading edge of the intermediate paper around the paper winding machine, but the paper winding shaft and the strip unwinding shaft are separate bodies. Therefore, an electric control device is required to synchronize the speed of the winding shaft with the unwinding speed of the intermediate paper, that is, the running speed of the IJ strip, which changes from moment to moment. There is a problem that the device needs to be equipped with a tension control circuit, an electric detector, and a tension control circuit to prevent the device from becoming stuck.

[Purpose of the invention]

An object of the present invention is to provide a simple means for changing the winding speed of an interlayer insert that is wound from between the layers of a metal sheet or the unwinding speed of an interlayer insert that is unwound between the layers of a metal sheet. An object of the present invention is to provide an unwinding and winding device for a metal plate interlayer insert, which can be easily tuned and prevents defects such as cutting and wrinkling of the insert.

[Summary of the invention]

To easily loosen the interlayer paper inserted between the layers of the metal plate, and to allow winding or feeding without cutting it during winding or unwinding.
To take it out, it is enough to completely synchronize with the feed speed of the metal plate and take it up or send it out at nine speeds.

A method for achieving complete synchronization is to directly contact the metal coil being unwound or wound, but since the metal plate itself does not have sufficient rigidity to withstand the pressure of the intermediate paper coil, the contact between the two is sufficient. power cannot be secured.

Therefore, in order to obtain such synchronized speed between the intermediate paper and the metal plate, the present invention utilizes a differential V-ctor roll that guides the metal plate, and uses a simple method of pressing the intermediate paper coil against this through the metal plate. The object of the present invention is to realize an unwinding and winding device for interlayer inserts of nine metal plates, which measures the synchronized feeding and eliminates the need for special control for speed synchronization.

That is, the present invention is characterized by a metal processing machine that processes metal continuously while running, and at least one of a metal unwinding machine and a metal winding machine disposed on the entry side and the metal winding machine on the exit side of the metal processing machine, respectively. In addition, in a metal unwinding machine, an interlayer insertion part is inserted between the layers to prevent the metal surface from bottoming out, and then a coil of the metal plate is unwound, and in a metal winding machine, when winding the metal plate, In the metal processing equipment configured to wind up the interlayer insert while putting it therein, the metal unwinding machine is provided with an insert winding machine for winding up the interlayer insert and a roller, and the metal plate is sandwiched between the two. and press the insert winder against the metal plate on the roller;
By providing a drive device for separating the insert, the coil circumferential speed of the insert wound around the insert winder is synchronized with the feeding speed of the metal plate while winding is performed.

In addition, the metal winding machine of the present invention is further provided with an insert unwinding machine and another roller, both of which are disposed at a position to sandwich the metal plate, and By providing a second drive device which is attached to the insert unwinder and presses the outer periphery of the next coiled insert against the metal plate on the other roller and performs a separation operation, the insert is unwound from the insert unwinder and then inserted. The object is to unwind while synchronizing the peripheral speed of the object with the feed speed of the metal plate.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An intermediate paper unwinding and winding device for a metal plate, which is an embodiment of the present invention, will be described below with reference to FIG. The figure shows an embodiment applied to rolling equipment having a reversible rolling mill 1, in which 2' is a metal plate unwinder, 3' is an entrance deflector roll, and 4' is an intermediate paper winder. The figure shows the passing direction of the metal plate 5 from right to left, but if the rolling mill 1 is a reversible type, the next bus will pass in the opposite direction from left to right, and both the metal plate and the intermediate paper will be unwound. The machine becomes a winding machine, and the winding machine becomes an unwinding machine.

The metal plate unwinding machine 2' unwinds a coil 6' containing intermediate paper 7 between the layers of the plate. Intermediate paper 7' on metal plate 5 (shown by dotted line)
When the intermediate paper 7' is unwound to the vicinity of the differential V controller 3' with the paper on it, the winding device 11' of the intermediate paper reel 4' separates only the intermediate paper 7' from the metal plate 5 and reels the intermediate paper reel. 4
Wrap it around the winding cylinder of '' and wind it up. Therefore, only the metal plate 5 is supplied to the rolling mill 1 and rolling is performed. The intermediate paper reel is supported by the arm 12' on the stand of the rolling mill main body 4', and the deflector roll 3 is supported by the cylinder 8'.
′, then it can be released upwards. The metal plate 5 rolled by the rolling mill 1 is wound up again by the winding machine 2, and at the same time, the intermediate paper 7 is supplied from the intermediate paper reel 4 on the deflector roll 3 installed on the exit side of the rolling machine, and the metal plate 5 It rides on the top surface of the metal plate and enters between the layers of the metal plate. Intermediate paper 7
The reason why the is pressed against the metal plate 5 is to obtain a rotating force that synchronizes the speed of the intermediate paper reel 4 and the metal plate, and to press the intermediate paper reel 4 on the winding side.
' is intended to control the winding force of the winding intermediate paper 7'. The pressing position of the intermediate paper reels 4' and 4 is the metal plate 5.
It is best to press it directly onto the deflector rolls 3', 3 holding the metal plate coils 6', 6 themselves. For example, the ratio of the outer diameter to the inner diameter of the intermediate paper reel 4ζ and 4 is usually 3~
Since the bearing of the intermediate paper reel is a rolling bearing and the rolling resistance is small, and the coefficient of friction between the metal plate and the outer diameter of the intermediate paper coil is large, only a small pressing force is required, but the flatness of the intermediate paper reel Since it may be difficult to rotate the intermediate paper reels 4, 4', it is preferable to auxiliarily drive the winding cylinders of the intermediate paper reels 4, 4' using a pneumatic motor or the like. (In the figure, 9 indicates an auxiliary motor, and lO indicates a unipart joint.) The pressing pressure can be controlled, for example, by calculating the change in the outer diameter of the intermediate paper reel 4.4' using the tachometer 13. The pressure of the pressing cylinders 8', 8 against the deflector roll 3.degree. 3' may be controlled in accordance with the reel diameter. It is preferable to reduce the pushing force as the outer diameter increases.

The winding device 11 may be an automatic type using an installed spray device or an adhesive tape pasting device, or it may be a simple manual type device for the first time, which grasps the leading edge of the intermediate paper.

According to the nine embodiments of the present invention described above, l) Since the intermediate sheets 7 and 7' are pressed against the deflector roll 3.3 through the metal plate 5, the intermediate sheets 7 and 7' are unwound or unrolled at the same speed as the metal plate 5. Since it is rolled up, there is no need to worry about running out of paper.

2) Since the intermediate paper 7, 7' is fed or wound up on the pattern of the metal plate 5, the paper does not get wrinkled.

3) When collecting the intermediate paper 7, 7', the intermediate paper rests on the surface of the metal plate 5, so that it can be wrapped at a low position. (The position of the deflector roll is usually about 1 meter from the work floor.) 4) When the deflector rolls 3 and 3' are pressed, frictional force acts between the rainbow metal plate 5 and the deflector rolls 3 and 3'.
Since the roll 3' can be rotated easily, the risk of slipping defects between the metal plate 5 and the rolls 3 and 3' is also reduced.

In addition to the above-mentioned improvements in performance and efficiency, the 4-way intermediate paper reel 4.4' is driven by the transfer of the metal plate 5, so the driving device can be powered by auxiliary IIX power, and there is no need to worry about running out of paper. Since there is no such thing, you can use a simple motor, or if you keep one, you can use a pneumatic motor, etc., which will greatly reduce costs.

〔Effect of the invention〕

According to the present invention, there is a simple means to adjust the winding speed of the interlayer insert that is wound from between the layers of the metal sheet, or the unwinding speed of the interlayer insert that is rolled out from between the layers of the metal sheet to the feeding speed of the metal sheet. cutting of the insert from the following, which allows for easy tuning by:
This has the effect of reliably preventing the occurrence of defects such as wrinkles.
