Abstract

PURPOSE:To miniaturize the whole device by attaching a touch roll to a cutting and holding head of a coil binding band and allowing it to execute a function of a pinch roll device. CONSTITUTION:First of all, an oscillation driving mechanism 2 operates, an oscillating arm 1 oscillates, and a touch roll 4 comes into contact with the outside surface of a coil C (two-point chain line position). Subsequently, an expansion/contraction driving mechanism 5 operates, a cutting an holding head 3 comes into contact with a binding band B of the coil C, and the head 3 cuts the band B and holes the end part. Next, the oscillating arm 1 oscillates counterclockwise, and the band B which is cut is unwound from the coil C (full line and dotted line positions). Thereafter, the expansion/contraction driving mechanism 5 operates, and the touch roll 4 presses the end part of the cut band B against a feed roll 6. The cut band B is inserted and held by the touch roller 4 and the feed roll 6, and fed into a band processor 8. Since a pinch roll is unnecessary, the device is miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a coil binding band cutting device that cuts a band binding coils, removes the cut band, and processes it as scrap. .

(B) Prior Art] The coiled belt is tied with a band to prevent loosening from the outer periphery of the coil when it is sent to the next process. When this coil is subjected to processing such as rolling or plating in the next step, it is necessary to cut and extract the band.

Conventionally, as one of this type of device,
There is a "strap cutting and removing device" disclosed in Publication No. 21. Its basic configuration is to cut and grip a band bound to a coil with a band cutting and gripping head provided at the tip of a swinging arm, and then remove the arm. A pinch roll device consisting of upper and lower rolls that swing rearward and open and close in a crocodile-like manner sends the binding band to a processing device located at the rear.

However, since the upper and lower rolls that open and close in a crocodile-like shape are pinch rolls, the height of the binding band cutting device increases, making the entire device large. Therefore, a problem arises when incorporating it into a limited open space such as an existing rolling mill.

(c) Problems to be Solved by the Invention The problem to be solved by the present invention is to make the entire device smaller by only slightly improving the existing device.

(d) Means for Solving the Problems The coil binding band cutting device of the present invention cuts the binding band from the coil placed on the coil mounting table and sends it to the band processing device. A swinging arm swinging between a coil mounting table and a band processing device, a mechanism for swinging the swinging arm, and a mechanism attached to the swinging arm so as to be extendable and retractable to cut the coil binding band. and a cutting/gripping head for gripping, a touch roller swingably and rotatably attached to the cutting/gripping head, and a telescoping drive mechanism for expanding and contracting the cutting/gripping head along the longitudinal direction of the swinging arm. and,
By means comprising a feed roller rotatably attached to the entrance of the band processing device and selectively engaging the touch roller, and a mechanism attached to the band processing device for rotationally driving the feed roller. , which solves the above problems.

(E) Embodiment An embodiment of the coil binding band cutting device of the present invention will be described with reference to FIG.

The main components of the device of the present invention are a swing arm 1, a swing drive mechanism 2, a cutting/gripping head 3, a touch roller 4, a telescopic drive mechanism 5, a feed roller 6, a rotation drive mechanism 7, and a band processing device 8. It consists of

The coil C bound with a band is placed on a coil mounting table 9.

The swinging arm 1 is rotatably attached to a fulcrum 11 and swings between the coil mounting table 9 and the band processing device 8. A swing drive mechanism 2 such as a fluid pressure cylinder is a swing arm 1
to drive the swing.

A telescopic drive mechanism 5 such as a fluid pressure cylinder is attached to the swing arm 1 . The tip of the telescoping drive mechanism 5 is cut and
A gripping head 3 is attached and is telescopically moved along the longitudinal direction of the swinging arm 1 by a mechanism 5. A touch roller 4 is rotatably attached to the cutting/gripping head 3.

A feed roller 6 is rotatably attached to the entrance of the band processing device 8, and is rotationally driven by a rotation drive mechanism 7.

(F) Function The function of the coil binding band cutting device of the present invention will be explained with reference to the drawings.

The swing drive mechanism 2 is operated to swing the swing arm 1 clockwise in the drawing, and the touch roller 4 is brought into contact with the outer surface of the coil C (the position indicated by the two-dot chain line). The telescopic drive mechanism 5 is operated to bring the cutting/gripping head 3 into contact with the binding band B of the coil C, and the head 3 cuts the band B and grips the end thereof.

Next, the swing drive mechanism 2 is operated again to swing the swing arm l counterclockwise, and the cut band B is unwound from the coil C (solid line and dotted line positions).

The telescopic drive mechanism 5 is activated again and the touch roller 4 presses the end of the cutting band B against the feed roller 6. The rotational drive mechanism 7 operates to rotationally drive the feed roller 6.

The cutting band B is held between the touch roller 4 and the feed roller 6, and is sent to the band processing device 8 by the feed roller. Band B is cut into an appropriate length by a cutting machine 10 and placed in a packet 11.

After band processing is completed, all mechanisms return to their initial positions and wait for the next processing.

(G) Effect The feature of the present invention is that the touch roller 4 is connected to the cutting/gripping head 3.
The point is that the roller C is brought into contact with the surface of the coil C reliably in parallel, and acts as one of the pinch rolls for sending out the binding band. As a result, the entire device can be made more compact than the conventional two-pinch roll system, which was provided separately. Therefore, if the present invention is applied when a coil binding band processing device is to be installed in a limited open space such as an existing rolling mill, effects can be obtained.
