Abstract

The invention discloses a control system and control method of an automatic cut-off machine; the control system of the automatic cut-off machine comprises a single-chip microcomputer, a switch plate, a knife-edge sensor, a cutter sensor, a cutter magnetic valve, a stepping motor driver and a stepping motor, wherein the switch plate, the knife-edge sensor and the cutter sensor are respectively connected at a corresponding input end of the single-chip microcomputer; the cutter magnetic valve and the stepping motor driver are respectively connected at a corresponding output end of the single-chip microcomputer; and the stepping motor is connected with an output end of the stepping motor driver. As the control system adopts the single-chip microcomputer technology, when the knife-edge sensor induces a lower knife edge, the single-chip microcomputer is triggered to control the stopping of a strip and the cutting-off of an upper knife edge; after the cutter sensor induces that a cutting mechanism finishes cutting-off operation, the cutter sensor sends out a control signal to the single-chip microcomputer so that a remaining zipper continues to move forward under the pulling of a strip pulling mechanism; and simultaneously, the single-chip microcomputer controls the strip pulling mechanism to pull the zipper by a knife-edge length and then stop pulling the strip and cut off the lower knife edge, thereby cutting out a special zipper product without strip ends at the two ends.

Description

The control system of automatic cutting off table and control method

Technical field

The present invention relates to slide fastener production equipment, specifically a kind of control system and control method of the automatic cutting off table for Zipper-cutting.

Background technology

Existing slide fastener, its structure before not cutting off as shown in Figure 1, article two, long ribbon shape strap A is side by side upper, is arranged at intervals with the chain tooth B of the corresponding engagement of multistage, and the upper blank strap between the chain tooth of each section of corresponding engagement of strap A is called takes the lead C (being the edge of a knife).In Cutting process, taking the lead C is upper edge of a knife C1 corresponding to the front end of slide fastener throughput direction, corresponding to the rear end of slide fastener throughput direction, is lower edge of a knife C2.

Automatic cutting off table generally comprises strap mechanism, cutter mechanism, and for controlling the control system of strap mechanism and cutter mechanism work.Existing automatic cutting off table, its control system mainly comprises power supply, strap mechanism driver, cutting knife solenoid valve, inductor and controller, by power supply, provide power supply for whole control system, inductor is installed near cutter mechanism and is electrically connected on the input end of controller, and strap mechanism driver and cutting knife solenoid valve are connected to the corresponding output end of controller.During work, controller starts, output enabling signal is to strap mechanism driver, the work of strap mechanism driver drives strap mechanism, long ribbon shape slide fastener under the pulling of strap mechanism to moving ahead, current line is during to edge of a knife inductor place, edge of a knife inductor first senses the negative edge of the upper edge of a knife C1 of slide fastener, then slide fastener continues to move ahead, edge of a knife inductor senses the rising edge of lower edge of a knife C2 again, now edge of a knife inductor sends signal to controller, controller output control signal is to cutting knife solenoid valve and strap mechanism driver, strap mechanism quits work, cutting knife solenoid valve is opened, the work of control cutter mechanism, cutter mechanism cuts a cutter between the upper edge of a knife of slide fastener and the lower edge of a knife, by cutting knife inductor induction cutter mechanism, finish and cut off after action, then cutting knife inductor is given signal of controller again, controller is exported control signal again to strap mechanism driver, residue long ribbon shape slide fastener continues to move ahead under the pulling of strap mechanism, until inductor senses the edge of a knife on the next one of slide fastener, so periodic cycle work.

In zipper product, be generally that the common zipper product of taking the lead is left at two ends, also have two ends all not stay the special zipper product of taking the lead.Will cut out one end from long ribbon shape slide fastener and leave the common zipper product of taking the lead, for every zipper product, shut-off mechanism only need move once, and shut-off mechanism only need cut just passable between the upper and lower edge of a knife of each edge of a knife of slide fastener; And will cut out two ends from long ribbon shape slide fastener, all do not stay the special zipper product of taking the lead, for every zipper product, shut-off mechanism need move twice, and on slide fastener, the upper edge of a knife of each edge of a knife and the lower edge of a knife all will cut off.

Because existing Zipper-cutting eedle can only partial application to each edge of a knife of slide fastener, for all special zipper products with taking the lead not of this two ends, existing Zipper-cutting equipment cannot be produced, so the present invention has designed a kind of stapling machine of controlling, cuts out all not control method of the special zipper product with taking the lead and control system used of two ends.

Summary of the invention

The object of this invention is to provide a kind of control system of automatic cutting off table, it can be controlled automatic cutting off table and cut out two ends and all do not stay the special zipper product of taking the lead.
