Embodiment approach 1
[0025] figure 1 It is a block diagram showing the configuration of the inter-roller conveyance control device 100 according to Embodiment 1 of the present invention.
[0026] The inter-roller conveying mechanism 1 is a mechanism that conveys a belt-shaped or linear conveying material 11 formed of materials such as paper, resin, metal, etc. between a plurality of rollers. By using the tension shaft motor 12 to drive the tension shaft roller 13 to rotate, The conveyance material 11 is thus wound up. In addition, the speed shaft roller 15 is driven to rotate by the speed shaft motor 14 so that the conveyance material 11 is wound out. Thereby, the conveyance material 11 is conveyed between the tension-shaft roller 13 and the speed-shaft roller 15 .
[0027] A tension control amount detector 20 is attached to the inter-roller conveyance mechanism 1 , and the tension control amount detector 20 outputs a tension detection value Tfb which is a tension control amount obtained by dete...
Embodiment approach 2
[0064] In the description of the roller-to-roll conveyance control device 100 according to the first embodiment, the roller-to-roll conveyance control device 100 adjusts the gain of the tension control computing unit 24 in a short period of time in an operation state at an arbitrary conveyance speed. In the embodiment, the adjustment of the gain of the tension control calculation unit is automatically performed before the start of the inter-roller conveyance operation at the time of initial startup.

Embodiment approach 3
[0083] In Embodiment 2, it is assumed that the amplitude of the added value D, that is, the amplitude of the tension axis velocity, is set in advance, and the added value amplitude D is the amplitude of the added value Vd at the time of adjustment as the output value of the binary output unit 125. However, it may also be configured to operate so that the oscillation amplitude of the tension deviation Te coincides with a value set in advance when the adjustment is performed.

Abstract
The inter-roller conveying control device has: a tension control amount detector, which detects the tension control amount; a speed axis speed controller, which performs control to make the conveying speed consistent with the speed axis speed command; a tension axis speed controller, which performs control to make the conveying speed Control consistent with the tension axis speed command; synchronous speed command generation unit that synchronizes the speed axis speed command with the tension axis reference speed command; tension control calculation unit based on the proportional compensation obtained by multiplying the proportional gain and multiplying the integral gain And the integral compensation obtained by integrating is output to the tension control correction value; the adjustment execution command generation part, which outputs the adjustment execution command during the automatic adjustment; One of the positive and negative values of the added value amplitude; the tension axis speed command generation part, which outputs the tension axis speed command based on the tension axis reference speed command, the tension control correction value, and the added value during adjustment; and the gain calculation part, based on The period and amplitude of the tension control deviation during automatic adjustment are calculated by proportional gain and integral gain.
Description
technical field [0001] The present invention relates to an inter-roller conveyance control device that keeps a belt-like or linear conveyance material formed of metal, resin, paper, etc. between rollers driven by a plurality of motors while maintaining the conveyance Material tension while conveying. Background technique [0002] In the conventional roller conveyance control device, as described in Patent Document 1, in order to convey the conveyed material between the two rollers stably and with a predetermined tension applied, there is a counter-roller rotational speed corresponding to each roller. The speed controller that performs control supplies a speed command corresponding to the speed of the line to each speed controller. At the same time, the tension of the conveyed material between the two rollers is detected by the tension control amount detector, and the tension controller for PI (Proportional-Integral) control or PID (Proportional-Integral-Derivative) control ...
