It will be appreciated that the method for controlling unreeling of the diaphragm during the work station changing process of the present embodiment may be applied to other devices besides the winder, and the present embodiment is not limited thereto.
The control method of the embodiment of the present invention may include, but is not limited to, including step S100, step S200, step S300, and step S400.
Step S100, first starting information for indicating a work station changing operation is received.
Specifically, when the winder meets the station change permission conditions, for example: the winder completes a series of working procedures, and when the working procedure needs to be restarted, for example, when the first electronic cam is successfully generated and then enters a rapid generation mode; the controller of the winder receives first start information for indicating a work position changing operation, and the work position changing of the winder can be started. The changing station of different winding machines is allowed to be different, and the changing station is set according to actual conditions.

Specifically, before the first electronic cam and the work position changing driving module are coupled, in the work position changing process of the work position changing driving module at a first speed, the controller collects and processes position relation data of the diaphragm encoder and the work position changing driving module, and the first electronic cam is generated according to the position relation, and then the first electronic cam and the work position changing driving module are coupled. It will be appreciated that the first speed is typically set to a relatively slow speed at which the encoder roller does not overshoot, and that the positional relationship data of the diaphragm encoder and the change position drive module acquired by the controller during the change position operation is relatively accurate, and that the first electronic cam is relatively reliable. Moreover, it can be understood that the smaller the speed of the work position changing driving module is, the smoother the curve of the position relation data of the diaphragm encoder and the work position changing driving module acquired by the controller is, the more the reality represented by the curve is enhanced, and the better the generated electronic cam is.
In an embodiment, the generating of the first electronic cam may include: receiving second starting information for indicating the work position changing operation, wherein the second starting information is one starting information before the first starting information, and the second starting information and the first starting information are different in effect, the second starting information is the starting information for starting the work position changing work performed by the information control diaphragm unreeling driving module of the diaphragm encoder matched with the work position changing driving module, and the first starting information is the starting information for starting the work position changing work performed by the coupled electronic cam control diaphragm unreeling driving module matched with the work position changing driving module; then the controller controls the station changing driving module to work at a first speed according to the second starting information, wherein the first speed is a slower speed preset according to the condition of the winding machine, namely a speed slower than the speed required by normal production; and then acquiring the acquired pulling parameters of the material belt of the diaphragm encoder, controlling the diaphragm unreeling driving module to unreel the material belt according to the pulling parameters of the material belt, acquiring the position relation data of the diaphragm encoder and the work position changing driving module in the process of controlling the diaphragm unreeling driving module by the encoder, and generating a first electronic cam according to the position relation data of the diaphragm encoder and the work position changing driving module. It will be appreciated that after the first electronic cam is generated, the first electronic cam needs to be detected, and if the detection indicates that the electronic cam is generated successfully, the reset station is required to be changed to perform relearning from the learning selection button, and a new electronic cam is generated. Wherein, it should be noted that the pulling parameters of the material belt include at least one of the following: the pulling amount of the material belt; the pulling speed of the material belt.
In an embodiment, the coupling process of the first electronic cam may be to determine the virtual axis as the slave axis and determine the axis of the work position changing driving module as the master axis according to the first start information, and then perform the coupling process of the virtual axis and the work position changing driving module through the first electronic cam.

It should be noted that there is no necessary relation between the first speed and the second speed, and if efficiency needs to be improved, the second speed may be set to a speed higher than the first speed, and if the production period is not urgent, the second speed may be set to a speed lower than the first speed, so as to ensure the yield of the produced product, which is not particularly limited in this embodiment.
And step S400, controlling a diaphragm unreeling driving module to unreel the material belt according to the first electronic cam and the second speed.
Specifically, the speed of the diaphragm unreeling driving module is calculated according to the first electronic cam and the second speed, then the diaphragm unreeling driving module is controlled according to the speed, the operation of changing the work position is carried out according to the first electronic cam, the stability of diaphragm unreeling synchronous speed control can be improved, and the occurrence probability of unstable problems such as diaphragm dislocation, diaphragm unreeling tension buffering sporadic reaching limit value alarm and the like caused by unreeling deviation correction abnormality due to large diaphragm tension fluctuation in the work position changing process is avoided.

In one embodiment, the controller in the winder is configured in two modes, one for learning the electronic cam generation mode and one for the fast production mode. Before a proper electronic cam is generated, a learning generation electronic cam mode can be started and generated firstly, in the mode, synchronous control processing is carried out on a diaphragm unreeling driving module according to data of an encoder, namely, second starting information for indicating station changing operation is received, then the controller controls the station changing driving module to work at a first speed according to the second starting information, the first speed is a relatively slow speed preset according to the condition of a winding machine, pulling parameters of a material belt collected by the diaphragm encoder are acquired, the diaphragm unreeling driving module is controlled to unreel the material belt according to the pulling parameters of the material belt, in the process of changing the position of the diaphragm unreeling driving module controlled by the encoder, position relation data of the diaphragm encoder and the position relation data of the station changing driving module are collected, after the first electronic cam is generated, the generated first electronic cam is detected, whether the first electronic cam is successful in generation, if the first electronic cam is successful in generation, the first electronic cam can be quickly shifted to a production mode if the first electronic cam is unsuccessful, and the first electronic cam can be newly generated again through the first learning mode again. Under the condition that the first electronic cam is successfully generated, a quick production mode is entered, first starting information for indicating work position changing operation is received, then the first electronic cam is coupled with the work position changing driving module, under the condition that the first electronic cam is successfully coupled with the work position changing driving module, the work position changing driving module is controlled to work at a second speed which is much higher than the first speed, the speed of the diaphragm unreeling driving module is calculated according to the first electronic cam and the second speed, the diaphragm unreeling driving module is controlled according to the speed, the stability of unreeling synchronous speed control can be improved through work position changing operation according to the first electronic cam, further diaphragm tension fluctuation in the work position changing process is reduced, and the occurrence probability of unstable problems such as diaphragm dislocation, diaphragm unreeling tension buffering sporadic reaching a limit value alarm and the like caused by unreeling deviation correcting abnormality due to large diaphragm tension fluctuation is reduced.
