Description

[Detailed description of the invention] This invention relates to a method for suspending and feeding a long coil to be cut into a roll forming machine, etc., and in particular, provides a flexible portion as a certain play width in the feeding coil, To avoid the inconvenience of over-traction of coils in a roll forming machine, and to automate the suspension of supplied coils and continuously drive the roll forming machine itself, effectively avoiding work loss due to stoppage of drive of the roll. The present invention relates to a flexible supply device for cutting coils which is adapted to provide a flexible cutting coil.

Conventionally, this type of cut coil was supplied to the roll forming machine directly from the coil cutting machine to the roll forming machine, so the feed speed of the cutting machine was affected by the amount of time the roll was taken back by the forming machine. This is due to the expansion or tearing of the coil when the speed is high.

In addition, the roll forming machine was started and stopped in conjunction with the cutter's constant operation for stopping and cutting the coil, which significantly reduced the workability of roll forming. That is, the weight of the rolls in the roll forming machine was large, which required a long time to stop the operation and made it extremely difficult to start and stop the rolls at the correct position, significantly reducing the work efficiency and causing unevenness in the product.

In order to solve the disadvantages of the conventional precedent, various configurations have been developed to bend the cut coil when feeding it to the roll forming machine, but these bending devices generally A device that is equipped with a guide roller that guides the coil to the roll forming machine and a support whose one end is a free end that supports the guide roller, and that operates the support that supports the guide roller. However, the machine is complicated and large-scale, lacks speed, and is difficult to operate, significantly shortening the service life of the machine.

The present invention was devised especially in view of the inconveniences in the prior art, and includes a pair of side frames extending from the roll forming machine side toward the cutting machine side, and a coil guide section provided on the side frames. A separate coil feeding device is configured with a coil feeding device, and this feeding device appropriately controls the supply of coils, and the roll forming machine itself is not driven, stopped, or changed speed at all. , the coil feeding device itself can be simplified, the roll forming machine can be made smaller and simpler, the durability of the roll forming machine can be improved, and buck crushing or excessive winding in the roll forming machine can be reliably prevented. It is something.

In addition, generally speaking, a gap equivalent to the length of the cutting coil is required between the cutting machine and the forming roll, but in the present invention, the cutting coil is bent and pooled above the frame, so that the distance between the cutting coil and the forming roll is equal to the long width of the cutting coil. In addition to supplying smooth coils, this installation space is not required, and the forming roll cutting machine can be installed in a relatively narrow space.

In order to achieve appropriate and purposeful effects on these characteristics, the present invention provides a gist of the structure of a coil installed between a fixed-length continuous cutting machine a for the coil 1 and a roll processing machine for the cutting coil 1. The coil feeding device b includes a pair of side frames 4, 4 extending from the fixed-length continuous cutting machine a side toward the roll processing machine side, and extending over the side frames 4, 4. It consists of a pair of upper and lower pinch rolls 5, 5 provided on the side of the roll processing machine, and the side frames 4, 4 have an upper surface guide 9 in contact with the upper surface of the coil 1 to be supplied;
A guide plate 7 supports the lower surface of the coil 1, and the upper guide 9 and the guide plate 7 constitute a running guide groove S supporting the side edge of the coil 1. A guide plate 7 constituting S is rotatably supported by the side frames 4, 4, and the coil 1 held by the pinch rolls 5, 5 is bent and dropped between the side frames 4, 4. The following embodiments and corresponding design changes are planned.

Hereinafter, details of the present invention will be explained with reference to a typical embodiment shown in the drawings. A is a coil cutting machine, and b is a roll forming machine (not shown) that uses the cutting machine a to cut the coil 1. This relates to a coil supply device for delivery to (omitted).

Therefore, the coil cutting machine a is planned to be of all types that are used for cutting the general coil 1 to a fixed length,
The coil 1, which is transported with rolls 2, 2, is cut with shear rings 3, 3.

Next, the feeding device b is a pair of side frames 4 installed between the coil cutting machine a and the roll forming machine which are usually installed, and is detachably fixed to each machine.

The supply device b is equipped with a pair of upper and lower pinch rolls 5 mounted near the end of the side frame 4 where the roll forming machine is attached, and the pinch rolls 5 are driven by a motor 6. At the same time, a signal device for regulating the opening and closing of the circuit of the motor 6 is installed slightly toward the end of the roll forming machine by means of a pinch roll 5. In particular, this signal device is installed at the top of the side frame 4 in the direction in which the coil 1 is transferred. A pair of photoelectric elements 10, 10 are provided on the lower surface and are installed in such a manner that they are cut off by the coil 1.

The drive motor 6 of the pinch roll 5 opens the motor switch with a signal input by the coil 1 cutting off the photoelectric elements 10, 10, and at the same time closes the TR circuit.
When the TR circuit is closed, the running motor circuit is closed to drive the motor 6 again, and the amount of deflection of the coil is ensured during this time.

Next, a guide plate 7 is rotatably supported on both sides of the side frame 4, and a running guide groove S for the supply coil is formed between the guide plate 7 and the upper surface guide 9 of the side frame 4. The guide plate 7 is rotated by photoelectric elements 10, 10 provided on the pinch roll 5.

In one example, the supply coil is connected to the photoelectric element 1.
0 and 10 is used as an input signal to open the circuit path of the solenoid 8 used to drive the guide plate 7, and at the same time open the roll drive circuit of the cutting machine a. The input signal is the release of the cut-off accompanying the end of supply, and is used as an input signal to complete the operation.

These circumstances are exactly the same in direct circuit opening and closing when the photoelectric elements 10, 10 are replaced with micro switches or the like.

The present invention has a unique structure as described above, and in particular, when the pinch roll 5 is driven and stopped, the coil 1 is bent and remains below the side frame 4, so that it can effectively cope with the traction of the forming roll. The drive stop of the pinch roll 5 and the movement of the roll forming machine are completely eliminated, and rather the operation is planned to be linked with the cutting machine a, which can be easily controlled.

Therefore, in the coil supply device b according to the present invention, the coil cutting machine a and the roll forming machine are not directly connected, and the coil 1 as a buffer structure is deflected, thereby preventing overwinding of the coil by the roll forming machine. Alternatively, it reliably prevents forming defects due to changes in drive and stop positions, bump crushing, etc., as well as various losses associated with stopping the drive of large rolls, especially significant deterioration in work efficiency.

Further, in the coil supply device b according to the present invention, the cut end of the coil 1 to be transferred to the pinch rolls 5, 5 provided on the side of the roll processing machine is provided on the side frames 4, 4, and the cut end of the coil 1 is provided on the side frames 4, 4, and 1, and a guide plate 7 that supports the lower surface of the coil 1. This prevents lateral protrusion and lateral slippage, and eliminates the inconveniences caused by these.

It should be noted that even by using the method of rotating the guide plate 7 described above and pulling the guide plate 7 laterally at a horizontal level, the lower part of the coil guide surface could be made into a deflection gap. 7 can be directly retracted using a hydraulic cylinder or solenoid rod, or it can be slid freely using a suitable driving medium such as a lever.

Thus, at the same time that the coil 1 is held between the pair of upper and lower pinch rolls 5, 5, the guide plate 7 is released so that the coil 1 is bent by its own weight, and the coil 1 and the pinch rolls 5, 5 are not forced. After bending the coil by a certain length without generating excessive force, the cutting machine is activated, and the cut coil 1 is immediately sent to the roll forming machine by re-driving the pinch rolls 5, 5. This is how it was done.

In addition, as mentioned above, the space that should be interposed between the cutting device a and the roll forming machine is minimized by using the space below the coil supply surface three-dimensionally, thereby increasing the installation efficiency and operating efficiency of these devices. In addition, the interposition of such a feeding device b makes it possible to connect the cutting device a and the roll forming machine, regardless of differences in conditions between the individual cutting devices a and the roll forming machine. It is something.

That is, when a roll forming machine is directly connected to the cutting device a as in the prior art, it is required to adjust and connect the drive speeds of each machine according to the respective feed speeds or take-up speeds.
If it was necessary to change the roll forming machine from time to time, it would be necessary to adjust the rotational speed of both machines and correct the rotational unevenness each time, and such setting errors would immediately cause molding defects. It is something.

The supply device b according to the present invention has the amount of deflection of the coil 1 by itself, and can eliminate the disadvantages of the prior art.

As mentioned above, the present invention enables relatively long cut coils to be supplied to a roll forming machine easily and reliably from a cutting device, and is a cut coil that promises to improve the forming efficiency and significantly improve the forming standard quality. This invention relates to the disclosure of a flexible feeding device.
