Problems solved by technology

However, the repeatability of continuous feed units is lower than that of batch units
In addition, there is a little drawback that when the operation speed is increased, the reduction in the accuracy of the repetition becomes very significant

Embodiment Construction

[0034] Fig. 1 is a view showing a compaction processing line 1, which is an example of the plastic processing system of the present invention.

[0035] The compaction processing line 1 includes two sets of compaction devices 2 for carrying out predetermined compaction processing on a coil C (ie, a workpiece). These two sets of compression devices 2 are referred to as the first compression device 2a and the second compression device 2b below.

[0036] In other words, the compaction processing line 1 includes: an uncoiler 3, that is, a conveying device for conveying the coil C; a first feeding device 4; an intermittent feeding mechanism 5a; a first compacting device 2a, that is, the previous compacting device tightening device; feeding regulating device 6; second feeding device 7; intermittent feeding mechanism 5b;

[0037] The first and second pressing devices 2a, 2b each have a metallic mold for performing a predetermined pressing process. In this connection, the basic const...

Abstract

The invention discloses a plastic working method and plastic working system. Particularly, a plurality of press devices (2) are arranged in a plastic working system. The plastic working system includes: a loop correction sensor (13) for watching a slack of a coil material (C) intermittently delivered from a preceding first press device (2a); and a second slack watching means (19) for watching a slack of the coil material (C) generated at the time of sending the coil material (C) to a succeeding second press device (2b). According to the slack generated by intermittent feeding of the coil material (C) sent from the first press device (2a), intermittent feeding is converted to continuous feeding by the feeding means (15). At the same time, the continuous feeding speed is subjected to speed increasing / decreasing control. On the other hand, by the second slack watching means (19), a slack of the coil material (C) is watched at the time of feeding the coil material (C) to the second press device (2b) and the preceding first press device (2a) is subjected to speed increasing / decreasing control.

Description

technical field [0001] The present invention relates to a plastic processing method and a plastic processing system in which a plurality of plastic processing devices are arranged in a processing line, workpieces can be stably supplied to the processing devices, and high-speed operation can be performed. Background technique [0002] In conventional plastics processing installations, for example, a conventional press device is incorporated in a press working line to which coil material (i.e. workpiece) is fed such that Coils can be processed by compaction, where the coil is fed from an uncoiler that supports and uncoils it, passes it through a leveler that straightens the coil, and passes the coil through a The area where the coil forms a loop (slack or loosening), and then the coil is sent to the compaction device via an intermittent feeding mechanism, so that the coil can be processed for compaction. [0003] In this case, the feeding operation of the coil to the pressing...
