Description

[Detailed description of the invention] [Industrial application field] The invention consists of an uncoiler that unwinds coiled material,
The present invention relates to a device for guiding the coil material from the uncoiler to the leveler, which is disposed between the coil material and a leveler which eliminates distortion and sends the coil material to a press machine.

[Conventional technology]

When the material to be pressed by the press machine is a coil material, the coil material is set on the coil material mounting shaft of the uncoiler, and the coil material is fed out from the uncoiler by the rotation of this mounting shaft.After this, the coil material is leveled. The strain is removed by a group of work rolls and then fed to a press machine.

Conventionally, the coil material mounting shafts of the uncoiler rotate in the same direction, and as a result, the coil material is always fed out from the uncoiler, for example, in a downward direction.For this reason, there is a gap between the uncoiler and the leveler as shown in Japanese Patent Laid-Open No. 55-31778. A guide member such as a guide apron is provided, and the coil material uncoiled from the uncoiler is guided to the leveler by this guide member, so that the coil material can be reliably introduced into the leveler.

[The problem that the idea aims to solve]

As mentioned above, conventional devices placed between the uncoiler and the leveler to guide the coil material to the leveler have a structure based on the premise that the coil material is fed out from the uncoiler in the same direction. was.

However, if the coil material is, for example, a steel plate coated on one side and the surface to be pressed by the press machine is determined, the feeding of the coil material from the uncoiler is also specified as, for example, upward feeding. In order to be able to work on various types of coil materials, the uncoiler's coil material mounting shaft should be able to rotate forward and backward so that the coil material can be brought out both downwards and upwards. Additionally, a device disposed between the uncoiler and the leveler for guiding the coil material to the uncoiler needs to be configured so that it can deal with both lowering and raising the coil material.

An object of the present invention is to provide a coil material guiding device that can reliably guide the coil material to a leveler regardless of whether the coil material is fed out from an uncoiler either downward or upward.

[Means to solve the problem]

For this reason, the coil material guiding device according to the present invention is
The coil material is placed between an uncoiler that feeds out the coil material by rotation of the coil material mounting shaft and a leveler that sends the coil material to the press machine without distortion. The device guides the coil material that is unwound and unwound to the leveler, and has a length extending from the leveler side to the uncoiler side, and has a posture angle that corresponds to the lowering and upward unwinding of the coil material. Equipped with a vertical swinging body that can be changed,
The coil material is guided to the leveler by passing between these oscillating bodies.

Each of the rocking bodies may be provided with blades that can move forward and backward toward the uncoiler, and these blades may substantially extend the length of the rocking body.

[Effect]

Since the feeding angle is different when the coil material is fed out from the uncoiler in the downward direction and when it is fed out in the upward direction, the attitude angle of the upper and lower rocking bodies is changed according to the downward movement and upward movement, and the coil material is The tip of the coil material is received by the upper swinging body, the tip of the coil material is received by the lower swinging member during lifting, and thereafter the coil material is passed between the upper and lower swinging bodies and guided to the leveler.

When each oscillator is provided with the blade, the blade is moved forward or backward in accordance with the coil diameter of the coil material set on the coil material mounting shaft of the uncoiler, and if the coil diameter is small, the blade is moved forward. This compensates for the lack of length of the oscillator up to the coil material.

The lower swinging body 14 is a guide table. Fourth
As shown in Fig. 5, the width dimensions of the opener 13 and the guide table 14 are different, but these 13, 1
4 has a length extending from the leveler 3 side to the uncoiler 1 side as shown in FIG. The guide table 14 is vertically swingable around a shaft 15 at the end on the leveler 3 side.
As a result, the guide table 14 swings up and down. Further, a shaft 15 is attached to the end of the opener 13 on the leveler 3 side.
A connecting member 17 extending from the opener 1 is connected to the opener 1.
3 is also vertically swingable about a shaft 15, and the opener 13 is caused to swing vertically by the cylinder 18.

As shown in FIG. 4, a blade 19 with a box-shaped cross section is installed inside the opener 13.
Guide grooves 2 formed in side members 19A, 19B of
A roller 21 rotatably attached to the side members 13A, 13B of the opener 13 is fitted into the blade 19, and the blade 19 is moved by the cylinder 22 shown in FIG. It is designed to move forward and backward toward the side. As shown in FIG. 3, a roller 23 is provided at the obliquely downwardly bent tip of the blade 19, and this roller 23 is rotated by a hydraulic motor 24 and a chain 25.

As shown in FIG. 5, a blade 26 made of a narrow rectangular material is installed in the center of the guide table 14 in the width direction.

Therefore, even if the opener 13 and the guide table 14 both swing up and down about the shaft 15, the coil unwound from the uncoiler 1 by these rollers 23 and 31 The material 8 can be reliably clamped.

Next, the effect will be explained.

As shown in FIG. 6, when the coil material mounting shaft 9 of the uncoiler 1 is rotated in the forward direction to feed out the coil material 8 from the uncoiler 1, first the opener 13
is placed in a horizontal position, the guide table 14 is placed in a downward position, and the blade 19 of the opener 13 is advanced. Next, the coil material mounting shaft 9 is rotated in the forward direction, whereby the coil material 8 that has been fed out is received by the V-shaped pedestal 7 of the coil car 6, and the coil material 8 that has been reversed upward is received by the V-shaped pedestal 7 of the coil car 6. The tip 8A of the blade 19 is received by the roller 23 of the blade 19. When the coil material 8 is continuously fed out from the uncoiler 1 and the amount of this feeding reaches a predetermined amount,
The blade 19 is moved back and the guide table 14 is swung upward to take a horizontal position, thereby moving the coil material 8 between the two rollers 2 as shown in FIG.

Thereafter, the coil material 8 is introduced between the opener 13 and the guide table 14 by the forward rotation of the coil material mounting shaft 9 and the roller 23 rotated by the hydraulic motor 24 and the chain 25, and the coil material 8 is introduced between the opener 13 and the guide table 14. The coil material 8 is passed through while being supported by the guide roller 30.
In this way, the leveler 3 is guided by the guide device 2.
Thereafter, the coil material 8 fed into the coil material 8 is deformed by a leveler 3 and then supplied to a press machine 4.

In the above, the rotation speed of the hydraulic motor 24 that rotates the roller 23 is set to be slightly faster than the speed at which the coil material 8 is fed out from the uncoiler 1.
Therefore, the coil material 8 is fed from the uncoiler 1 to the guide device 2 without being bent by this hydraulic motor 24, which has the function of a torque limiter.

As shown in FIG. 7, when the coil material mounting shaft 9 is reversely rotated to feed out the coil material 8 from the uncoiler 1 in an upward direction, the opener 13 is first swung to its upward swing limit and the guide table 14 is placed in an upward position. At the same time, the blade 26 of the guide table 14 is moved forward. Next, the coil material 8 is fed out from the uncoiler 1 in an upward direction, and the tip 8A of the coil material 8 is received by the blade 26. The coil material 8 is then fed out from the uncoiler 1, and when the amount of this feeding reaches a predetermined amount, the blade 26 is moved back. At the same time, the opener 13 is swung downward, whereby the coil material 8 is clamped by the two rollers 23 and 31. After this, the process is similar to the case of lowering the coil material 8 in FIG. The coil material is passed between 13 and 14 and the strain is removed by the leveler 3, and then the coil material is supplied to the press machine 4.

As described above, in this embodiment, the guide device 2 is provided with the opener 13 and the guide table 14 as vertically swinging bodies, and since these 13 and 14 are vertically swingable, the coil material from the uncoiler 1 is Regardless of whether the coil material 8 is fed out downwardly or upwardly, the attitude angle of the opener 13 and the guide table 14 can be changed according to the feeding angle of the coil material 8, and both downward feeding and upward feeding can be handled. become able to.

Further, the opener 13 and the guide table 14 are provided with a blade 1 that can freely move forward and backward toward the uncoiler 1.
9 and 26, when the coil diameter of the coil material 8 set on the coil material mounting shaft 9 of the uncoiler 1 is small, the blade 1
9 and 26 can be moved forward to compensate for the lack of length of the opener 13 and guide table 14 up to the coil material 8, and the opener 13 and guide table 14 can be substantially extended.

Although the rollers 23 and 31 were used in the embodiment described above, these rollers 23 and 31 may be omitted. However, as in the above embodiment, the roller 23,
31, it is possible to introduce the coil material 8 between the opener 13 and the guide table 14 reliably and safely.
