Abstract

PURPOSE:To coil a steel strip under tension without forming a steel strip loop before a coiling machine by rotating a coiling shaft through an intermediate shaft while reciprocating a sliding base in the shaft direction of the coiling shaft. CONSTITUTION:A coiling shaft 11 having a horizontal shaft body 11a projecting concentrically from one end of an expansion/reduction part 11b having a horizontal axis on which the steel strip A1 is coiled is arranged on the sliding base 22. A spline intermediate shaft 41 is arranged in parallel and at an interval with the coiling shaft 11 on the ground side. It is rotated by a drive motor 1 whose intermediate shaft 41 is arranged on the ground side. A rotation transmitting means is connected between a sliding cylinder 44 put on the intermediate shaft and the coiling shaft 11. While the sliding base 22 is reciprocating in the shaft direction of the coiling shaft 11, the coiling shaft 11 is rotated through the intermediate shaft 41. In this way, dispersion of coiling is prevented and in transport, handling of the coil after the strip is coiled, the need for the special purpose core having a disc flange can be diminished.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip winding method and device.

[0002]

2. Description of the Related Art In order to increase the unit weight (unit weight) of a steel strip coil, that is, to lengthen the length of one strip plate and wind it into a cylindrical shape, a narrow strip plate is unwound from the coil. ,
Oscillate the bobbin of the winder. Conventionally, the strip is wound by simply swinging the strip in the width direction and rotating the winder.

[0003]

However, in order to shake the strip, it is necessary to take a loop (free the strip) in front of the winder, which requires a long equipment. Also, since tension cannot be applied to the strip,
The winding machine needed a dedicated core (bobbin) with a disk collar. Since the bobbin and the coil are integrated and carried after the winding, there is a disadvantage that only the bobbin must be returned after the coil is delivered at the delivery destination.

The present invention solves the above problems, and provides a method and apparatus for winding a strip that can be wound by applying tension to the strip without forming a loop on the strip before the winder. The purpose is to

[0005]

In order to solve the above problems, the structure of the present invention is as follows. That is, in the method of the first configuration, the winding shaft having the horizontal shaft main body protruding concentrically from one end of the expansion / contraction portion having the horizontal axis around which the strip is wound is installed on the slide base, and the winding shaft is parallel to and spaced from the winding shaft. The spline intermediate shaft is installed on the ground side, and the intermediate shaft is rotated by a drive motor installed on the ground side, and rotation transmission is performed between the sliding cylinder fitted on the intermediate shaft and the winding shaft. The means is connected, and the winding shaft is rotated through the intermediate shaft while reciprocating the slide base in the axial direction of the winding shaft.

In the apparatus of the second structure, the shaft main body extends horizontally concentrically from one end of the expansion / contraction part having a horizontal shaft around which the strip is wound, and the winding part is rotatably supported by the bracket.
A slide base on which the winding unit is mounted is reciprocally movable in the axial direction of the winding shaft, and a feed screw rod is screwed into a feed nut member fixed to the slide base. , A reciprocating drive unit having a double clutch connected to its end, a reciprocating power transmission unit connected to the reciprocating drive unit, and a spline shaft rotatable parallel to the sliding path of the slide base and horizontally separated from each other. And a connecting piece fixed between the sliding base slidably fitted on the spline shaft and the sliding base to rotate between the sliding cylinder and the winding shaft body. It is intended to include a rotary power transmission unit to which a transmission unit is connected, and a drive motor connected to the rotary power transmission unit and the reciprocating power transmission unit.

In addition to the second structure, the device of the third structure is such that the reciprocating power transmission section is parallel to the rotation axis of the double clutch.
A first intermediate shaft rotatably provided at intervals in the horizontal direction, forward and reverse rotation transmission means provided between the first intermediate shaft and the rotary shaft of the double clutch, and the first intermediate shaft And a continuously variable transmission connected to the.

[0008]

When the drive motor is rotated, the first intermediate shaft is rotated by the transmission means in the reciprocating power transmission section, whereby the forward and reverse transmission means are simultaneously rotated. For example, in the case of normal rotation, the feed screw rod rotates, the slide base moves forward through the feed nut member, the double clutch is replaced by the signal from the position detection means, and the feed screw rod stops and the forward screw rod moves forward. The rolling clutch is released and the reverse clutch is engaged. This causes the feed screw rod to start reversing. Then, the slide base is retracted, the feed screw rod is stopped again by the signal of the position detecting means, and the feed screw rod starts forward rotation again by the reverse operation.

At the same time, in the rotary power transmission section, the spline shaft is rotated by the drive motor, and while the sliding cylinder and the drive sprocket are rotated, they are moved together with the slide base by the connecting piece. As a result, the winding shaft is rotated via the rotation transmission means.

Means 33 are connected. The chain transmission means 34 and the continuously variable transmission 35 are connected to the intermediate shaft 31.
Are connected.

In the rotary power transmission section 40, the sliding base 22 is
A second intermediate shaft spline shaft 41 is rotatably provided in parallel with the sliding path of the above, and is slidably fitted and inserted into the spline shaft and the slide base 22. A connecting piece 45 is provided between the sliding cylinder 44 and the winding shaft body 11a, and a rotation transmitting means is connected between the sliding cylinder 44 and the winding shaft body 11a. That is, the second intermediate shaft 41 is provided via the bracket 42, and one end of this intermediate shaft is connected to the chain transmission means 43 and is connected to the drive motor 1 described later. A sliding cylinder 44 having a splined inner surface is axially slidably fitted into the second intermediate shaft 41, and a drive sprocket 46 is fixed to the sliding cylinder 44 concentrically with the sliding cylinder 44. A driven sprocket 47, which is concentrically fixed to the main body 11a, is concentrically fixed to the boss portion 11c.
8 is suspended. In addition, the circumferential groove 44 on the outer periphery of the sliding cylinder 44
The forked portion of the connecting piece 45 fits inside a, and the guide roller 45a is provided at the tip of the forked portion. The other end of the connecting piece 45 is fixed to the side surface of the slide base 22. With this configuration,
As the connecting piece 45 moves linearly, the sliding cylinder 44 moves in the axial direction while rotating.

The drive motor 1 is connected to the rotary power transmission section 40 and the reciprocating power transmission section 30 through chain transmission means. That is, the first chain transmission means 1 a is provided between the drive motor 1 and the spline shaft 41, and the second chain transmission means 1 b is provided between the spline shaft 41 and the continuously variable reduction gear 35.

A disc 49a is fixed concentrically to one end of the boss 11c, and an air brake shoe 49b for the disc 49a is mounted on the slide base 22.

The operation state will be described above. Insert the core cylinder and the two discs (perforated) into the winding shaft expansion / contraction part 11b,
A bobbin is constructed by disassembling the two discs with tie bolts and nuts. Then, the winder is rotated, and the handle of the continuously variable transmission 35 sets the movement amount per one rotation according to the width of the strip. The turn position is determined by adjusting the distance between the strikers 28 while looking at the contact of the strip on the end face of the disc. Next, the tip of the strip is inserted into the groove of the expansion / contraction part 11b through the cutout of the core tube.

When the drive motor 1 is rotated, in the reciprocating power transmission section 30, the first intermediate shaft 31 moves to the chain transmission means 3.
It is rotated by 4 and thereby the forward and reverse transmission means 3
2, 33 gears rotate simultaneously. In the case of normal rotation, the feed screw rod 24 rotates and the feed nut member 2 is rotated.
When the slide base 22 moves forward via 3 and the proximity switch 27 protruding on the side surface of the slide base approaches the front end striker 28, the double clutch 25 with brake is replaced by the signal, and the feed screw rod 24 is When stopped, the forward clutch is released and the reverse clutch is engaged. This causes the feed screw rod to start reversing. When the slide base 22 moves backward and the proximity switch 27 approaches the rear end striker 28, the feed screw rod 24 is stopped again, and the feed screw rod 24 starts to rotate forward again by the reverse operation.

At the same time, in the rotary power transmission section 40, the second intermediate shaft 41 is rotated by the drive motor 1 and the sliding cylinder 44 and the drive sprocket 46 are rotated, while the connecting piece 44 moves together with the slide base 22. As a result, the driven sprocket 47 rotates via the chain 48, which causes the winding shaft 11 to rotate.

The brake means 49 is for preventing the coil from being dislocated when the winder is stopped (when the line is stopped). The brake means 49 presses the brake shoe 49b against the disc 49a by air, and the friction force is applied. , Stop the rotation of the winder.

After winding the strip having a required weight, the expansion / contraction portion 11b of the winding shaft is contracted, the coil is extracted by the stripper cylinder and placed on the unloader. On the unloader, remove the tie rod, remove the disc, and disassemble the assembly bobbin, and then band-tie the coil and core tube with a sealer to prevent coil dislocation. It will be shipped in this state.

In the above embodiment, one drive motor 1
Since it reciprocates with the rotation of the winding shaft 11,
It is reliable and inexpensive to synchronize the moving speed per rotation. Uses an electromagnetic double clutch with a brake for quick turn response. Since the continuously variable transmission is used, it is easy to adjust the movement amount of the winding shaft per one rotation according to the width of the strip plate.

The present invention is not limited to the examples and embodiments described above, but includes various modifications without departing from the spirit and scope of the claims.

[0024]

According to the first structure of the present invention, it is not necessary to form a strip loop in front of the winding machine, and the apparatus can be shortened. In addition, since the steel sheet is wound under tension and there is no coil deviation, there is no need for a dedicated core (bobbin) with a disk collar when transporting and handling the coil after winding.

With the second structure, in addition to the effects of the first structure,
Especially, since the double clutch and the spline shaft are used, the rotation and axial movement of the winding shaft can be performed by one drive motor.
Therefore, the rotation speed and the movement speed per one rotation are surely synchronized, and the cost is low.

With the third structure, in addition to the effects of the second structure,
The amount of movement of the take-up reel per rotation according to the plate width can be set arbitrarily and easily.
