Abstract

PROBLEM TO BE SOLVED: To easily guide a hoop and to improve productivity by providing a hoop tip straightening device, which is arranged with plural rolls connected to a drive device above/under a transfer route, between a slit device and tension device. SOLUTION: A strip recoiled by a recoiling machine 1 is sent to a slit device 3, the strip is cut/separated in strip like shape by making plural slits to produce a hoop 5. The hoop tip is sent into between the upper/lower roll 11 of a straightening device 10, deformation such as bulging, twisting, etc., at hoop tip is straightened by the upper/lower rolls 11 rotated with the drive device. Successively, the hoop is sent to a coiling machine through a tension device 6 by feeding action of the roll 11 rotated by the drive device, the hoop 5 is coiled by the coiling machine 8. By making whole length of the hoop 5 pass between upper/lower rolls 11 of straightening device 10, deburring and straightening can be executed over the whole length of the hoop.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoop manufacturing facility equipped with a hoop tip straightening device for straightening a plurality of strips of hoop tips slit by a slitter.

[0002]

2. Description of the Related Art Narrow strips, that is, hoops (steel strips) are manufactured by dividing a wide strip into a plurality of slits by a slit device and dividing the strip into strips.

FIG. 3 is a conventional production line diagram of a hoop, in which a strip 2 rewound from a wide coil mounted on a rewinding machine 1 has a slit device 3 having a plurality of rotary blades 4.
Insert multiple slits with. The tip of the hoop 5 which is sheared and separated into strips by a plurality of slits is guided to a winder 8 through a tension device 6 and a deflector roll 7 and wound up. The tension device 6 applies tension to the hoop 5 wound by the winder 8, and a pad system, a belt bridle system, or a roll system is used.

Since the tip of the hoop is bulged and twisted during shearing and the tip of the hoop is not aligned, smooth guidance to the tension device is not possible. It is guided to the winder through the device.

However, although it is easy to manually correct the deformation of the thin hoop, it is troublesome to correct the deformation of the thick hoop.

Therefore, in order to facilitate the guidance of the tip of the hoop, it has been put to practical use to guide the tip of the hoop with a plate carrier (see Japanese Patent Publication No. 57-4479).

FIG. 2 is a manufacturing line diagram in which the tip of the hoop is guided by using a threading truck. The strip 2 rewound by the rewinding machine 1 is sheared into a strip shape by a plurality of slits by the slit device 3, and the tip of the hoop 5 separated is clamped by the plate passing cart 9. The plate carrier 9 having the hoop tip clamped moves on the rail and passes through the tension device 6 in which a tension applying portion such as a pad, a belt or a roll is opened to allow the plate carrier 9 to pass, and the hoop 5 is removed. Guide to the winder 8.

[0008]

However, in the case of using the above-mentioned plate passing cart, since the plate passing cart is passed between the tension devices, means or transfer for forming an opening for passing the plate passing cart in the tension device is required. Since the means is required, the tension device becomes large.

Therefore, the present invention provides a hoop manufacturing facility which can easily guide the hoop in a hoop manufacturing line equipped with a slit device without enlarging the tension device.

[0010]

SUMMARY OF THE INVENTION The present invention is a hoop manufacturing facility in which a strip rewinder, a slit device, a tension device, a deflector roll, and a winder are sequentially arranged, and between the slit device and the tension device. A hoop tip straightening device is provided in which a plurality of rolls connected to a driving device are provided above and below a hoop conveyance path.

The hoop tip straightening device may be movably arranged between the slit device and the tension device.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a hoop manufacturing line diagram incorporating a hoop tip straightening device of the present invention. In the hoop production line, a rewinding machine 1, a slit device 3, a hoop tip straightening device 10, a deflector roll 7, and a winding machine 8 are sequentially arranged.

The slit device 3 has a plurality of rotary blades above and below the strip running passage in order to form a plurality of slits in the strip 2 rewound from the wide coil mounted on the rewinding machine 1.

The hoop tip straightening device 10 comprises a plurality of rolls 11. Since the hoop tip straightening device 10 needs to straighten the deformation of the hoop tip and forcibly feed the hoop 5, each roll 11 is rotated by a driving device (not shown).

The tension device 6 applies tension to the hoop 5 wound on the winder as in the conventional tension device, and uses a pad system, a belt bridle system or a roll system.

Next, the hoop tip straightening device 10 of the present invention.
The operation of the hoop manufacturing line incorporating the is explained. The strip 2 rewound by the rewinding machine 1 is sent to the slit device 3, and a plurality of slits are inserted to shear the strip into strips and separate the strips into hoops 5.

The tip of the hoop is fed between the upper and lower rolls 11 of the straightening device 10, and the upper and lower rolls 11 rotated by the driving device correct the deformation of the hoop tip such as bulge and twist.

The straightened hoop tip is tensioned by the feeding action of the roll 11 which is rotated by a driving device.
And the hoop 5 is wound up by the winder 8. The entire length of the hoop 5 is the upper and lower rolls 11 of the straightening device 10.
Deburring and straightening can be performed over the entire length of the hoop by passing it between the two.

Next, another embodiment of the present invention will be described. In the above-mentioned embodiment, the straightening device is fixed after the slit device, but in order to surely insert the hoop 5 into the tension device 6, the straightening device 11 can be moved by a carriage as shown by a broken line in FIG. 1 (see FIG. 1). From position A to position B).

[0020]

【The invention's effect】

(1) In the straightening device, the deformation of the tip of the hoop is straightened by the roll rotated by the driving device, and the hoop is conveyed, so that the hoop can be easily guided and the productivity is improved.

(2) By making the correction device movable, the hoop can be reliably inserted into the slit device.

(3) If the entire length of the hoop is passed between the rolls of the straightening device, deburring and straightening can be performed over the entire length of the hoop.
