Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The invention aims at increasing the function of color code cutting on the basis of the original cross-cutting machine, and proposes a solution to the problem of missing marks during the color code cutting process.

[0025] like figure 1 As shown, it is a cross-cutting machine system with color code cutting function. When working, employees input parameters such as mechanical size and actual given cutting length L from man-machine interface 1. When servo controller 2 receives these parameters , planning the cutting electronic cam curve table inside it. When the cardboard 3 starts to be tra...

Abstract

The invention relates to a color mark shearing method implemented by a transverse cutting machine, and belongs to the field of movement control. The color mark shearing method includes implementing a color mark shearing function by the aid of compensation for a spindle when detected color marks are normal; setting a compensation value as 0 after loss of a certain color mark is discovered, and switching into a fixed-length shearing working mode; judging the relation between a set judgment distance xi*L and the distance L2 from the position of a new color mark to the position of a last shorn point after a signal of the new color mark is detected, directly using the L2 as a given cut length when the L2 is larger than or equal to the xi*L, using the xi*L as a given cut length when the L2 is smaller than the xi*L, repeating the procedure until the L2 is larger than or equal to the xi*L, and implementing a mark searching function. The color mark shearing method has the advantages that the color mark shearing function and the automatic mark searching function are implemented, the automatic mark searching function is implemented after the certain mark is lost, accordingly, functions of the transverse cutting machine are increased, and the labor cost is reduced during corrugation paper production.

Description

technical field [0001] The invention relates to a control method for a corrugated paper cross-cutting machine, in particular to a control function of a cross-cutting machine capable of realizing color-mark cutting, and in particular to a control system for a cross-cutting machine with a color-mark cutting function. The method of finding the color mark after the color mark is lost. Background technique [0002] The cross-cutting machine is the throat of the corrugated paper production line, and its working performance directly affects the efficiency of the corrugated paper production line. In order to increase the overall production speed of corrugated paper, corrugated paper production is now gradually integrated with printing, and printing is carried out at the same time as production. This requires the cross-cutting machine to be able to accurately cut according to the color code on the cardboard. At present, some cross-cutting machines have realized the function of color...
