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
Technical field
The present invention relates to the slide fastener production equipment, specifically is a kind of control system and control method that is used for the automatic cutting off table of Zipper-cutting.
Background technology
Existing slide fastener, its structure before not cutting off is as shown in Figure 1, on two long ribbon shape strap A side by side, is arranged at intervals with the chain tooth B of the corresponding engagement of multistage, and the blank strap on the strap A between the chain tooth of the corresponding engagement of each section is called takes the lead C (being the edge of a knife).In cutting off technology, taking the lead C is last edge of a knife C1 corresponding to the front end of slide fastener throughput direction, is edge of a knife C2 down corresponding to the rear end of slide fastener throughput direction.
Automatic cutting off table generally comprises drawstring mechanism, cutter mechanism, and the control system that is used to control drawstring mechanism and cutter mechanism work.Existing automatic cutting off table; Its control system mainly comprises power supply, drawstring mechanism driver, cutting knife solenoid valve, inductor and controller; By power supply is that The whole control system provides power supply; Inductor is installed near the cutter mechanism and is electrically connected on the input end of controller, and drawstring mechanism driver and cutting knife solenoid valve are connected to the corresponding output end of controller.During work, controller starts, and the output enabling signal is given drawstring mechanism driver; Driver drives drawstring mechanism of drawstring mechanism work, long ribbon shape slide fastener under the pulling of drawstring mechanism to moving ahead, during current line to edge of a knife inductor place; Edge of a knife inductor is sensed the negative edge of the last edge of a knife C1 of slide fastener earlier, and slide fastener continues to move ahead then, and edge of a knife inductor is sensed down the rising edge of edge of a knife C2 again; This moment, edge of a knife inductor sent signal to controller, and controller output control signal is given cutting knife solenoid valve and drawstring mechanism driver, and drawstring mechanism quits work; The cutting knife solenoid valve is opened, the work of control cutter mechanism, and cutter mechanism downcuts a cutter between the edge of a knife on the slide fastener and the following edge of a knife; Through cutting knife inductor induction cutter mechanism finish cut off action after; The cutting knife inductor is given signal of controller more then, and controller is exported control signal once more and given drawstring mechanism driver, and residue long ribbon shape slide fastener continues to move ahead under the pulling of drawstring mechanism; Sense the edge of a knife on the next one of slide fastener until inductor, so periodic cycle work.
In the slide fastener product, generally be that the common slide fastener product of taking the lead is left at two ends, the special slide fastener product that also has two ends all not stay to take the lead.Will cut out an end from the long ribbon shape slide fastener and leave the common slide fastener product of taking the lead, to every slide fastener product, shut-off mechanism only need move once, and promptly only need cutting-out between the upper and lower edge of a knife of each edge of a knife of slide fastener is just passable for shut-off mechanism; All do not stay the special slide fastener product of taking the lead and will cut out two ends from the long ribbon shape slide fastener, then to every slide fastener product, shut-off mechanism need move twice, and promptly the last edge of a knife of each edge of a knife all will cut off with the following edge of a knife on the slide fastener.
Because existing Zipper-cutting eedle can only partial application to each edge of a knife of slide fastener; For this two ends all not with the special slide fastener product of taking the lead; Existing Zipper-cutting equipment can't be produced, and cuts out two ends all not with the control method of the special slide fastener product of taking the lead and used control system so the present invention has designed a kind of stapling machine of controlling.
Summary of the invention
