it should be noted that the pressure roller 30 is in a normal state, may be in a normal speed range, or may be in a rotating process, and is preset according to actual needs. The pressing roller 30 is in a normal state, that is, the conveying assembly 20 is in a normal operating state, and therefore, a command for continuing the operation is given to the conveying assembly 20, and the conveying assembly 20 continues the operation.
If the press roller 30 is not in a normal state, a command to stop the operation is issued to the conveyance unit 20.
It should be noted that the pressure roller 30 is not in a normal state, may be in an abnormal speed range (too slow), may be in a rotation stopping process, or may be still in an abnormal state after being adaptively controlled, for example: after the speed of the press roller 30 is slowed down, the conveying speed of the conveying assembly is improved through adaptability, and the normal conveying condition still cannot be maintained, and the condition is preset according to actual needs. The press roller 30 is not in a normal state, that is, the conveying assembly 20 is abnormal, so that an instruction for stopping the operation is sent to the conveying assembly 20, and in order to avoid the damage of the conveying assembly 20, the conveying assembly 20 stops the operation and waits for the maintenance of a worker.
Still further, if the pressing roller 30 is not in the normal state, the step of instructing the stopping operation of the conveying assembly 20 includes:
after the state of the pressing roller 30 continues for a predetermined time, a stop instruction is issued to the feeding unit 20.
It should be noted that the threshold of the preset time is preset in the controller, and may be a value from 3s to 5s, preferably 3s, and after the preset time, that is, the conveying assembly 20 continues to be abnormal for 3s, the operation stop is sent to the conveying assembly 20, so as to avoid the erroneous judgment caused by the abnormality due to the small fault.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
