CN102560773A - Method for controlling bobbin discharging motor of doffing machine - Google Patents

Abstract

A method for controlling a bobbin discharging motor of a doffing machine includes: firstly, a FPGA (field programmable gate array) master controller drives a bobbin push motor to rotate positively to push a bare bobbin into a tray and then rotate reversely to an initial position; secondly, the FPGA master controller drives a tray motor to rotate positively to an assigned angle, a sensor outputs signals to a relay, the relay picks up and turns on an electromagnet on a tray, the electromagnet opens a bare bobbin guard, and the bare bobbin slips onto a spike of a spinning machine along the tray under the action of gravity; and thirdly, the FPGA master controller drives the tray motor to rotate reversely, and the tray returns to the initial position and awaits next discharge of a bare bobbin. The method has the advantages that automatic bobbin discharge is achieved, productivity is improved, operating environment is improved, labor can be saved, and enterprise competiveness can be improved.

Description

A kind of doffer is put the control method of pipe motor

Technical field

The present invention relates to a kind of control method of motor, relate in particular to the control method that a kind of doffer is put the pipe motor.

Background technology

Now, domestic a large amount of old-fashioned short spindle spinning frames still adopt manual work that full spool is taken off from spindle, change empty spool again.Because full spool and spindle bonding force closely need very big tube drawing power, also will change empty spool simultaneously.Thereby certainly will make cost increase with reduction production efficiency very greatly by doffer's labour intensity like this; On the other hand, because the spinning workshop noise is big, temperature is high, air pollution is serious and abominable production environment, make that the workman who is ready to be engaged in the work of doffing is fewer and feweri, enterprise faces very big recruitment pressure.Therefore, very urgent for the old-fashioned short spindle spinning frame demand that process automation transforms of doffing.

Summary of the invention

The object of the present invention is to provide a kind of doffer to put the control method of pipe motor, realized that doffer puts pipe automatically, raised the efficiency, saved human resources.

The present invention realizes like this, realizes that the device of this method comprises FPGA master controller, ejector sleeve motor, pallet motor, electromagnet and sensor, and the FPGA master controller connects ejector sleeve motor, pallet motor, electromagnet and sensor respectively; It is characterized in that method is:

(1) FPGA master controller driving ejector sleeve motor is rotated in the forward empty spool is pushed in the pallet, and then initial position is got back in reverse rotation;

(2) after FPGA master controller driving tray motor is rotated in the forward specified angle; Sensor output signal is given relay; The electromagnet on the pallet has been connected in the relay adhesive, and electromagnet is opened the blank pipe guardrail, and empty spool is because gravity is slipped on the nail of spinning machine along pallet;

(3) FPGA master controller driving tray motor reverse rotation, pallet is got back to initial position, waits for blow-down pipe next time.

Technique effect of the present invention is: realized that automation puts pipe, not only increased productivity, improved working environment, also can save manpower, improved enterprise competitiveness.
