Problems solved by technology

As a result, the stamping line is significantly longer in the case of thick materials compared to thin materials
[0011] And, considering that the conventional system described above has a section where the material becomes free during the flow of the coil 1 from the uncoiler 2 to the intermittent feeder 7, a slight jump of the material in this section can damage the quality of the material
in such as Figure 8 In the device of the above-mentioned patent publication shown, since the material is suspended from an upstream portion of the ring control device 4, there will be a long period of time before the start of the feeding operation. Risk of remaining, thus recurring deflection, and slight jumps in the material at the moment of starting and stopping the feed, and thus chafing

Embodiment Construction

[0036] figure 1 It is a schematic diagram of a main structure of a stamping production line according to an embodiment of the present invention. Reference numeral 11 denotes a coil. The coil 11 is unwound by an uncoiler 12 . Reference numeral 13 denotes a coil supply device according to an embodiment of the present invention. The coil supply device 13 is provided with a coil supply section 22 as described below, and position sensors 23 and 24 for detecting the loop length of the coil 11, and these sections are mounted on a frame 25 in such a manner that it can be operated by A height adjustment device 20 adjusts its height. After the coil material 11 passes through the coil supply device 13 and forms a loop, the coil material 11 is fed through a batch supply device 28 to a mechanical press 27 to perform a stamping.

[0037] In the coil supply device 13, the coil supply section 22 includes a pair of supply rollers 14 and 15 for conveying the coil 11, a servo motor 16 for r...

Abstract

In a coil material feeding apparatus which has a reduced bouncing in spite of a high speed operation, can lower the load of the intermittent feeding apparatus, and can shorten the line length of the press stamping line, a position sensor for detecting a loop amount of a coil material and a coil material feeding portion are provided, the coil material feeding portion is provided with feeding rollers and a material correcting portion, and a mounting angle of the coil material feeding portion can be changed in correspondence to a thickness of the coil material and the like.

Description

technical field [0001] The present invention relates to a coil supply device for an intermittent supply device for supplying coil material to a mechanical press in a stamping line. Background technique [0002] Such as Figure 7 As shown, in a conventional stamping line, a coil 1 is fed from an uncoiler 2, passes through a straightener 3 for straightening the material and for producing a loop 5, known as a looper (looper), to an intermittent supply device 7 for supplying the coil 1 to a mechanical press 6. The straightener 3 is a device for straightening the coiled state in the coil, and presses the upper and lower rolls arranged alternately against each other, usually by pressing the upper roll down on the lower roll, thereby The material is continuously stretched and compressed so as to flatten the web. The straightener 3 generally consists of a pinch roll and a straightening roll. The pinch rollers serve as a part of pulling in the material, and the straightening rolle...
