Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) 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.

(Prior art and its problems) Conventionally, as a general method for bundling small-diameter coils that cannot be bundled on a coil car, as shown in FIG. The coil holder 13 of the coil car is raised according to the diameter, and the tail end of the strip is pressed against the coil holder 13 with the bottom surface of the coil to prevent it from being unwound.
Two workers stand on both sides of B, one side (A side)
The operator on the opposite side (side B) passes the tip of the binding hoop 14 through the conduction groove 15 drilled in the coil holder 13 from the lower side of the coil, and the operator on the opposite side (side B)
was passed around the outer circumference of the coil and returned to the worker on side A, and both ends of the binding hoop were tied together.

However, this coil binding method requires at least two workers, is inefficient, and has problems from the viewpoint of work safety since the binding work must be performed in a narrow and dangerous place.

The purpose of the present invention is to solve the above-mentioned problems.
To provide a method for safely and efficiently bundling coils on a mandrel.

(Means to Solve the Problems) In order to achieve the above object, the present invention makes a hoop conductive to a hoop conduction groove provided along the circumferential direction of the coil on the upper surface of the coil holder, and
After inserting into each hoop conduction groove of the presser roll having an annular hoop conduction groove on the circumferential surface and the lower winding guide plate having a hoop conduction groove on the upper surface and having a hoop guide plate attached so as to be able to rise and fall, the above hoop guide While the plate is erected, the tip of the hoop protruding upward is guided by an upper winding guide plate, thereby winding the hoop around a coil and binding the coil on a mandrel.

In other words, one worker conducts the hoop through the hoop conduction groove provided in the coil holder, and then connects the hoop to the hoop guide plate of the lower winding guide plate of the presser roll.
By operating the upper guide plates, the hoop is automatically wound into a coil, making it possible to easily bundle the coils on a mandrel.

(Example) Hereinafter, the present invention will be explained in detail with reference to the drawings which are one example.

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 around a bearing 5 that is pivotally 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 moving.

A strip tail end presser roll 7 is rotatably supported at the tip of the lower winding guide plate 2.

This presser roll 7 is used to prevent the tail end of the strip being wound from losing tension when it passes through a mill (not shown) that applies tension to the strip being rolled, making winding impossible. When near the end, the hydraulic cylinder 6 is actuated to press the presser roll 7 against the outer peripheral surface of the coil to prevent the coil 8 from loosening and wind it to the end.

The winding guide plate 3 has its base end supported via a shaft pin 11 on a bracket 10 at the upper end of a machine stand 9 that is erected, and a hydraulic cylinder 1 attached to the back.
2, the winding is guided while swinging in response to changes in the coil diameter.

A coil holder 13 of a coil car is disposed below the coil 8 wound by the mandrel 4, and the coil 8 is placed in a hoop by raising and lowering the coil holder according to the coil diameter. They are tied together by a coil car and then transported by a coil car.

Next, a method of bundling the coil 8 wound up as described above will be explained.

The coil 8 is bound by winding a hoop 14 around the outer periphery of the coil, and tightening both ends of the hoop 14.The binding hoop is wound by passing the hoop 14 through the lower side of the coil from the direction A on the side of the coil. It is made to project in the B direction, then sent upward, and is carried out by going 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 is for inserting the binding hoop 14 through the lower surface of the coil placed on the coil holder 13, and the tip of the hoop is passed from this groove 15 to the opposite side.

Next, in order to wind the tip of the binding hoop inserted on the opposite side upwardly along the outer periphery of the coil, a presser roll 7 supported on the tip of the lower winding guide plate 2 is used.
An annular conduction groove 16 is bored in one or several places on the same line as the conduction groove 15 of the coil holder 13 described above, and the binding hoop 14 passes upward through this annular conduction groove 16. However, the tip of the hoop separates from the outer peripheral surface of the coil and bends from the presser roll 7 onto the upper surface of the lower winding guide plate 2 and rides on it.

In order to guide this upward along the outer peripheral surface of the coil, one or more bundling hoop guide plates 17 are attached to the lower winding guide plate 2 .

The binding hoop guide plate 17 has a hoop conduction groove 18 on its upper surface, is fitted into a cutout hole 19 bored in the upper surface of the lower winding guide plate 2, and has a front end with a shaft pin 20 that connects the lower winding. 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.

Therefore, during the strip winding operation, the binding hoop guide plate 17 is placed face down in the cutout hole 19 so that the winding can be guided without any support. The binding hoop 14 is erected and rests on this upper surface.
While pushing back toward the outer circumferential side of the coil, it is further sent upward.

In this way, the binding hoop 14 is sent upward while being guided counterclockwise along the outer circumference of the coil, and in order to further pass over the upper surface of the coil and wind it around the coil 8, the binding hoop 14 is sent upward by the upper winding guide plate 3. By lowering the hoop to a position slightly away from the outer circumferential surface of the coil as shown by the shaded line, the tip of the binding hoop can be
It comes into contact with this and is guided along the outer periphery of the coil, passing over the upper surface of the coil.

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 coil holder 13 due to its own weight.

In this way, both ends of the binding hoop wound around the outer periphery of the coil are tightly tied to complete the coil binding.

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.

(Effects of the Invention) As described above, according to the present invention, since the upper and lower winding guide plates can be used as binding devices for coils on a mandrel, the binding work is extremely efficient, and moreover, only a small amount is required using the existing winding device. This is possible by modifying the .

Moreover, these coil bindings can be done by one person by simply feeding the binding hoop from the outside to the bottom of the coil, winding the coil once, and then tying both ends of the binding hoop, which greatly improves work efficiency. Moreover, since the tightening work is performed at a safe position without upper and lower winding guide plates, the work is also safe.
