Method for controlling slitter-scorer apparatus

Abstract

A method for controlling a slitter-scorer apparatus in which a feed line for a paperboard sheet does not need to be stopped when order specification of cutting or scoring for the paperboard sheet has been changed, thereby reducing a setup time, is proposed. A method for controlling a slitter-scorer apparatus including steps of supplying a paperboard sheet along a feed line, and moving a slitter or a scorer in a vertical and / or a widthwise direction to a operative level where the surface of said paperboard sheet is processed thereby wherein: movement of said slitter and / or scorer is controlled such that said slitter and / or scorer either come into sliding contact with or is apart slightly from said surface of the paperboard sheet.

Description

Technical field [0001] The present invention relates to a control method of a slitting and marking machine, and more specifically, to a control method of the slitting and marking machine, that is, the method can prevent the supplied corrugated board from snaking when the order instruction of the corrugated board is changed , To ensure the qualified rate of corrugated cardboard and shorten the time required for adjustment. Background technique [0002] In the prior art, corrugated cardboard such as single-sided corrugated cardboard, double-sided corrugated cardboard, or multi-layer double-sided corrugated cardboard is continuously supplied along the supply line, and is cut (cut) along the supply direction by a slitting and marking machine. If necessary, they should also be scored along the supply direction, so that they can be assembled as cardboard in the box-making process of the subsequent process. [0003] The slitting and marking machine is equipped with multiple slitting mac...

AI Technical Summary

Problems solved by technology

According to this technology, although the corrugated cardboard that cannot be discarded as a product before the adjustment is damaged, the supplied corrugated cardboard will meander, and this meandering will affect the processing after the adjustment, and the processing must be interrupted.

Therefore, in this technique, in order to prevent said meandering, the speed of movement of the slitter has to be controlled in relation to the feeding speed of the cardboard

[0014] Second, there is a problem of low yield of finished products of corrugated cardboard

[0015] Especially recently, with the increase in the supply speed of corrugated cardboard, the problem of low yield of finished products has become more and more serious.

[0016] The third point is that it is difficult to implement by processing the slitting machine or the scribing machine for the fluctuation of the processing conditions accompanying the change of the order instruction, and the external disturbance generated on the processing device side during processing or on the corrugated cardboard side as the processed product. Highly fine-tuned for flexible handling
