Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for bundling strip coils that are continuously fed out from a leveler or other various processing devices and wound around a mandrel.

Conventional method: A common method for bundling small-diameter coils that cannot be bundled on a coil car is to raise the coil A holder of the coil car in line with the coil diameter at the same time as the strip winding is completed, and then move the tail end of the strip into the coil. In addition to pressing the coil with the bottom side against the coil cradle to prevent it from unwinding, two workers stand on both sides holding the coil, and the worker on one side holds the end of the binding hoop from the bottom of the coil into the coil cradle. The worker on the opposite side wrapped the hoop around the outer circumference of the coil, returned it to the previous worker, and tied both ends of the binding hoop.

However, this method of bundling coils requires at least two workers, which is inefficient, and also poses problems in terms of work safety since the bundling work must be carried out in a narrow and dangerous place.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for safely and efficiently bundling coils on a mandrel in order to solve the above-mentioned problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below with reference to drawings which are one embodiment.

First, to explain the winding of the strip, the strip 1 carried out from the rolling mill (not shown) is guided by the lower winding guide plate 2 and the upper winding guide plate 3, and is coiled around the mandrel 4. It is designed to be wrapped around. □ The lower winding guide plate 2 is swingably mounted on a bearing 5 supported by the guide roll 2a, and is swung by a lower hydraulic cylinder 6 as the coil diameter increases. It is designed to guide winding while

At the tip of the lower winding guide plate 2, an IJ lug tail end pushing tail end rule 7 is rotatably supported.

When this presser roll passes through a mill (not shown) that applies tension to the IJ whirl during rolling, the tension disappears and prevents the winding from becoming impossible. To do this, when the tail end is near, the oil field cylinder 6 is operated to press the presser roll 7 against the outer peripheral surface of the coil, and the coil 8 is pressed against the outer peripheral surface of the coil.
This is to prevent the thread from loosening and wind it all the way to the end.

The lower winding guide plate 3 is attached to the bracket 1 at the upper end of the machine stand 9 which is installed upright.
The base end of the coil is supported by a shaft pin 11, and the winding is guided by swinging in response to changes in the coil diameter by the operation of a hydraulic cylinder 12 attached to the back. .

A coil pedestal 13 of the coil car is arranged below the coil 8 wound by the mandrel 4, and the coil 8 is bound by a hoop by raising and lowering the coil pedestal according to the coil diameter. It is now being transported by coil car.

Next, a device for bundling the eight coils wound as described above will be explained.

The coil 8 is bound by wrapping the hoop 14 around the outer circumference of the coil.
The binding hoop is wound by pushing the coil through the lower side of the coil from the side of the coil in the direction (A) shown in the figure, and then protruding in the opposite direction (B).
Next, it is sent upward and is carried out around the outer circumference of the coil.

To guide the winding of the binding hoop 14, first, one or more hoop conduction grooves 15 are bored on the upper surface of the coil holder 13. This connects the binding hoop 14 to the coil cradle 1
It is passed from the groove 15 under the coil placed on the coil to the opposite side.

Next, in order to wind the end of the binding hoop inserted on the opposite side upwardly along the outer periphery of the coil, the previously described coil holder 1 is mounted on the presser roll 7 supported on the end of the lower winding guide plate 2.
An annular conduction groove 16 is bored at one or several places on the same line as the conduction groove 15 of No. 3, and the binding hoop 14 is sent upward through this annular conduction groove 16.
- The tip of the coil is bent away from the outer circumferential surface of the coil and bent from the presser roll 16 to the upper surface of the lower winding guide plate 2, and in order to guide it upward along the outer circumferential surface of the coil, the lower winding guide One or more binding hoop guide plates 17 are attached to the plate 2.

The binding hoop guide plate 17 has a hoop conduction groove 18 on its upper surface, and is fitted into a cutout hole 19 bored in the upper surface of the lower winding guide plate 2, and has a front end connected to the lower winding guide plate with a shaft pin 20. It is pivotally supported by the guide plate 2 and can be raised and lowered toward the outer peripheral surface of the coil by a hydraulic cylinder 21 attached to the lower surface.

During the strip winding operation, the strip is placed face down in the cutout hole 19 so that winding guidance can be performed without any trouble, and
When guiding the binding hoop, the binding hoop 14 which is raised up as shown by the shaded line in the figure and riding on the upper surface of the binding hoop 14 is pushed back toward the outer periphery of the coil and sent further upward.

In this way, the bundle 7-p14 is fed upward while being guided counterclockwise along the outer circumference of the coil. By lowering the plate 3 to a position a little apart from the outer circumferential surface of the coil as shown by the shaded line in the figure, the tip of the binding hoop is guided into contact with the plate 3 and is sent along the outer circumference of the coil and passes over the upper surface of the coil. become.

After passing over the upper surface of the coil, the binding hoop descends along the outer periphery of the coil to the position of the L-shaped support 13 due to its own weight.

. Yo, 3ii 2. □□. 5. ,! Ah, I will finish the binding by tying both ends of the nib.

If the coils are to be bound at several locations, the coils can be bound at the same time by providing a plurality of conductive grooves in which the binding hoops are drilled on the same line and a plurality of undulating binding hoop guide plates at predetermined intervals.

As described above, according to the present invention, since the upper and lower winding guide plates for the coils on the mandrel can be used as a binding device, the binding work is extremely efficient, and moreover, it is possible to make the binding work possible with an existing winding device with a slight modification. .

What's more, these coil bindings can be done by one person by simply feeding the binding hoop from the bottom of the coil from the outside and winding the coil around the coil once.Then, all that is left to do is to tie both ends of the binding hoop, making the work extremely efficient. Moreover, the work is safe because the work is done at a safe position without upper and lower winding guide plates.
