Abstract
The invention discloses an electric control system of printing head with position and speed teaching functions, comprising teaching panel with accelerating and decelerating buttons and direction control keys. The teaching panel is connected with PLC with power-down holding register and the PLC is connected with transducer. The transducer is connected with the motor driving working table of lead screw move and the working table of lead screw is connected with code machine. The cod machine is connected with high speed counting module of PLC. The invention is provided with reasonable structure and it can adjust position and speed of printing head conveniently. It can decrease sensor damage.
Description
Technical field:
The present invention relates to a kind of parts that are applied to rotary automatic printing machine.
Background technology:
The stamp operation to dress material is finished in the general reciprocating motion of adopting pneumatic or electronic realization doctor of printing head on the automatic printing machine.At present, the movement position adjustment of domestic printing head all adopts the method for manual adjustment sensing station to determine, adjusts difficulty, repeatedly adjusts the position, also causes sensor to damage easily.By regulating pneumatic circuit valve openings size or regulating motor speed control squeegee speed, adjustment process needs repeatedly repeatedly, and non-cutting time is long.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructurely, can adjust the printing head electric control system that has position, speed tutorial function that the position of printing head and speed, minimizing sensor damage easily.
Technical solution of the present invention is:
A kind of printing head electric control system that has position, speed tutorial function, it is characterized in that: comprise the teaching panel that is provided with acceleration button and direction operating key, the teaching panel is connected with the PLC that is provided with power down maintenance register, PLC is connected with frequency converter, frequency converter is connected with the motor that drives the action of leading screw workbench, the leading screw workbench is connected with code machine, and code machine is connected with the high speed counting module of PLC.
Operation principle of the present invention is:
The speed teaching:
By tutorial function key and acceleration on the teaching panel, deceleration key, change the numerical value that the inner power down of PLC keeps register, and by the RS485 communication, the numerical value of revising is sent in the frequency converter, change frequency converter running frequency, thus motor rotation speed adjusted, and then change stamp speed.After arriving satisfied stamp speed, the speed teaching finishes, and stored parameter keeps register to the PLC power down, each start operation, and the allocating register data are carried out initialization to speed automatically.
The position teaching:
By tutorial function key on the teaching panel and direction of motion operating key, printing head moves forwards or backwards by the speed of setting, rotary encoder output pulse is to high speed counting module, after arriving the target location, unclamp direction of motion operating key, write down current umber of pulse, deposit the PLC power down in and keep register.Same quadrat method, the umber of pulse of record other direction target location is preserved data.During stamp, the data that PLC reads according to high speed counting module and the position data of teaching are relatively determined the printing head operation interval.
The present invention is rational in infrastructure, in order to overcome existing printing head in the deficiency aspect position and the speed adjusting, the invention provides a kind of printing head, realize tutorial function, need not the manual adjustment sensing station position, speed with tutorial function, realize position, speed setting by the teaching panel fully, realize What You See Is What You Get, in case set, parameter is promptly preserved, automatically access parameter during each the start, realize initialization position and speed parameter.The position and the speed of the adjustment printing head that the present invention is more succinct reduce sensor and damage.Owing to do not regulate mechanical part, regulate more quick simultaneously.Occasion for frequent variation printing flower type needs frequent stamp interval and speed, the particularly suitable of the present invention of changing.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is a software flow pattern.
The specific embodiment
Adopted altogether among Fig. 1 with lower member: the high speed counting module 2 of PLC1, PLC, encoder 3, motor 4, frequency converter 5, leading screw workbench 6.
A kind of printing head electric control system that has position, speed tutorial function, comprise the teaching panel 7 that is provided with acceleration button and direction operating key, teaching panel 7 is connected with the PLC1 that is provided with power down maintenance register, PLC1 is connected with frequency converter 5, frequency converter 5 is connected with the motor 4 that drives 6 actions of leading screw workbench, leading screw workbench 6 is connected with code machine 3, and code machine 3 is connected with the high speed counting module of PLC.
PLC is the core of system, operation control program, memory location, speed parameter; Encoder is connected with motor and leading screw workbench as sensor, measures motor rotation revolution and is converted to pulse signal; The umber of pulse of high-speed counter record rotary encoder output is determined current scraper present position; Frequency converter and PLC communication realize the speed adjusting of motor and the control of the direction of motion; Driven by motor leading screw workbench and the scraper that is mounted thereon realize back and forth scraping motion; All operations is realized by the teaching panel, be need not to adjust hardware parameter and frame for movement.
Fig. 2 software judges at first whether the teaching button is in teach mode, if not, move back and forth in the operation interval that teaching is determined by the controlled seal carving flower of directionkeys scraper, can move freely doctor position this moment.
If be in teach mode, judgement is speed teaching or position teaching.If acceleration, retard button are pressed in the speed teaching, the frequency converter output frequency increases, reduces 0.01Hz every 10ms, after arriving satisfied speed, unclamp the teaching key, the power down that then current running frequency value is saved in PLC keeps in the register, will be with this speed operation during doctor work.
If position teaching, after one in pressing the both direction operating key, scraper moves in the direction, the rotary encoder output pulse signal feeds back to the high-speed counter module of PLC, determines the doctor current location, after arriving desired location, unclamp directionkeys, preserve the current location value and keep register to the PLC power down, other direction extreme position value adopts with quadrat method to be determined.
