Embodiment 1

[0079] On the man-machine interface 15, the time t used by the cutting and pressing rollers from receiving the signal to pressing to receiving the new roll is respectively set. 1 =0.16, unit s; the time t used by the cutting knife from receiving the signal to cutting the material 2 = 0.08, unit s; the circumference of the new roll of receiving material C = 1055, unit mm; during cutting, the length L of the cutting pressure roller before the cutting tape is L = 300, unit mm; during cutting, the length of the tail of the cutting material Length S=200, unit mm;

[0080] The printing equipment runs at the highest line speed V max =300, m / min; set the equipment to accelerate from zero speed to the highest line speed time T=60, unit s.

[0081] The acceleration time of the preset printing equipment is t=50, the unit is s, and the line speed is calculated by formula (1)

[0082] V=(50×300) / 60=250, unit m / min.

[0083] During the cutting process, calculate C-L=1055-300=755, unit m...

Abstract

The invention discloses a discharging small tail length cutting control method for printing equipment. The method specifically comprises the following steps that before the printing equipment runs, parameters are set on a human-computer interface; the printing equipment is started and accelerated, the linear velocity V of a host is calculated, and an old material collecting roll runs according to the velocity V; discharging cutting preparation is made; the cutting press roller discharging time T<press> and the cutter discharging time T<cutter> in the discharging cutting process are calculated, and the average unit of T<press> and T<cutter> is s; and discharging small tail length cutting is achieved according to obtained T<press> and T<cutter>. When a discharging part of the printing equipment is used for roll replacement material collecting, the pressing distance of a material collecting press roll on a new roll and the cutting tail length are small, and therefore the aims of improving the overprinting precision and lowering printing waste losses in the discharging cutting process are achieved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment control, and relates to a control method for discharging short tail and long cutting of printing equipment. Background technique [0002] Cutting tail length: after the cutting is completed, the length from the tape of the new reel to the old reel. In the existing double-station discharging printing equipment, the cutting action of the discharging unit is as follows: press the "preparation for material receiving" button, the rotary frame will automatically rotate, and the cam on the rotary shaft acts on the travel switch during the rotary process, so that the cutting The cutting arm falls, and the slewing frame stops rotating after reaching the material receiving position. At this time, the new roll is at the material receiving position, and the pre-drive starts after a delay of 2S. When the axis speed of the new and old materials is synchronized, the synchronization indicator light is ...
