Problems solved by technology

[0004] The signal of the spindle encoder needs to be amplified by an external amplifier before being input to each tension control servo. The more tension control servos, the more amplifiers are needed that correspond to the tension control servos one by one. The wiring becomes very complicated and the failure rate high
Since the tension needs to be set for each axis and the real-time tension needs to be fed back, when the number of axes is large, the traditional Modbus communication bandwidth is limited, the communication speed becomes very slow, and the real-time performance of tension feedback is poor

Embodiment Construction

[0020] The present invention is further described in conjunction with the following examples.

[0021] The multi-axis servo tension control system includes a main shaft 1 and a plurality of unwinding shafts (unwinding shaft F1, unwinding shaft F2...unwinding shaft Fn) respectively arranged on both sides of the main shaft 1, multiple winding shafts (rewinding shaft S1, winding shaft S2 ...rewinding shaft Sn), the materials released from all unwinding shafts are integrated by the automatic roll changing mechanism 3 and then passed through the same unwinding tension sensor T2 to detect the tension, and then enter the main shaft 1 after being processed by the leveling mechanism and other processing mechanisms. The materials coming out of the main shaft 1 all go through the same winding tension sensor T1 to detect the tension, and then are separated by the automatic roll changing mechanism 3 and enter the corresponding winding shafts respectively.

[0022] All servo axes (spindle 1...

Abstract

The invention relates to the technical field of multi-shaft servo tension control systems, in particular to a multi-shaft servo tension control system based on CANopen buses. According to the multi-shaft servo tension control system based on the CANopen buses, a main shaft, multiple unwinding shafts and multiple winding shafts are provided with CANopen bus interfaces and achieve communication withone another through the CANopen buses, the connection is simple, the access priority is high, the message utilization rate is extremely high, and the transmission speed of signals is increased. All the winding / unwinding shafts can quickly obtain the rotation speed of the main shaft and the signals of a tension sensor, the calculation of the shaft speed of the system is completed in a servo, the shaft speed of the system is adjusted in real time according to a calculation result, and therefore the speed of each servo shaft is quickly adjusted.

Description

technical field [0001] The invention relates to the technical field of multi-axis servo tension control systems, in particular to a multi-axis servo tension control system based on CANopen bus. Background technique [0002] When the tension control accuracy is high, the tension control servo generally adopts the speed mode for control. This control mode needs to connect the encoder signal line of the spindle to the tension control servo, and the tension control servo is calculated by the encoder signal output from the spindle. The rotation speed of the main shaft, with the rotation speed of the main shaft as the feed-forward coefficient, combined with the winding diameter of the reel, calculates the feed-forward speed of the reel; at the same time, internally calculates the compensation speed according to the given tension and feedback tension, and the compensation speed and feed-forward The speed is superimposed and given as the rotation speed command of the winding and unw...
