The doffer controller and each winder controller are connected in the same way, and as shown in fig. 1, the doffer controller and one of the winder controllers 1 are connected in the following specific way: three output points (such as Q0.0, Q0.1 and Q0.2) of the doffer controller 1 are correspondingly connected one by one and control three relays K 11 、K 12 、K 13 Input terminals of, the three relays K 11 、K 12 、K 13 Are connected to the three input points of the winder controller 1 in a one-to-one correspondence. Wherein, the output point Q0.0 of the doffer controller controls the relay K 11 Q0.1 control relay K 12 Q0.2 control relay K 13 . Three output points (for example, Q3.1, Q3.2 and Q3.3) of the winder controller 1 are correspondingly connected one by one to control three relays K 14 、K 15 、K 16 An input terminal of (1); these three relays K 14 、K 15 、K 16 The output ends of the three input points are correspondingly connected with the three input points of the doffer controller one by one. Wherein the output point Q3.1 of the winder controller 1 controls the relay K 14 Q3.2 control relay K 15 Q3.3 control relay K 16 . The connection between the other winder controllers and the doffer controller is described with reference to fig. 1 and the above connection, and will not be described again.
In the specific implementation process, a plurality of doffers can be arranged on the same winder production line, and the same doffer controller is configured on the plurality of doffers so as to improve the doffing and transportation efficiency on the production line. The electrical connection between each doffer controller and the winder controller is the same, and is not described in detail here.
In an alternative embodiment, another input point (such as input point I4.7) of each winder controller may be used to access the doffing mode selection signal, where the input signal at input point I4.7 is 0: a manual doffing mode; the input signal at input point I4.7 is 1: automatic doffing mode. When the lower chuck of the winder has a package spinning cake, the signal is changed from 0 (manual doffing mode) to 1 (automatic doffing mode), and automatic doffing is carried out regardless of whether the winder is in a stopped state or in an operating state.
Specifically, another output point (for example, the output point Q3.7) of each winder controller is used for connecting a doffing status indicator lamp, and is used for indicating the current doffing mode of the winder, for example, the indicator lamp flashes corresponding to the manual doffing mode, the indicator lamp is normally on when the automatic doffing mode corresponds, and the other states are off.
In any of the winders on the winder line, after the winder forms a package cake requiring doffing, the corresponding winder controller first sends a doffing call signal to the doffer controller to call the doffer. And then, after receiving the winding doffing calling signal, the doffing machine controller feeds back an answer signal to the winding machine controller sending the doffing calling signal and controls the doffing machine to move to the position of the winding machine sending the doffing calling signal so as to wait for the chuck below the winding machine to stop running. The winder controller sends a ready signal to the winder until the chuck under the winder stops. And then, after receiving the ready signal of the winding machine, the doffer controller controls the wire shaft of the doffer to be positioned with the lower chuck of the winding machine, and sends the ready signal of the doffer after the positioning is finished. Then, the winding machine controller controls the winding machine to perform the bobbin releasing action and the bobbin pushing action after receiving the doffer ready signal, and cancels the doffer calling signal. And then, after the winding machine finishes the pushing cylinder action, the winding machine controller sends out a pushing cylinder finishing signal. And after the doffer controller receives the push-out completion signal, canceling the doffer preparation signal.
Based on the same inventive concept, an embodiment of the present invention provides a doffing control method for a winder production line, which is applied to a winder production line, wherein the winder production line includes doffers and M winders, and as shown in fig. 2, the doffing control method includes the following steps:
s201, when a target winding machine is in an automatic doffing mode and the doffing machine is in a working state, the target winding machine sends a doffing calling signal to the doffing machine, wherein the target winding machine is any one of the M winding machines which needs to doff a package spinning cake currently;
s202, the doffer feeds back a response signal to the target winding machine, the doffer is moved to the position of the target winding machine to wait for the target winding machine to stop running, and the target winding machine feeds back a winding machine ready signal to the doffer after the target winding machine stops running;
s203, the doffer responds to the ready signal of the winding machine, the filament shaft of the doffer and the lower clamping head of the target winding machine are positioned, and after the positioning is finished, the target winding machine feeds back the ready signal of the doffer to the doffer;
and S204, responding to the doffer ready signal by the target winding machine, and executing a bobbin loosening action and a bobbin pushing action on the coiled spinning cake on the target winding machine.
S205, after the target winding machine finishes the pushing action on the coiled spinning cake, the target winding machine feeds back a pushing completion signal to the doffer, and cancels the doffer calling signal and the winding machine ready signal;
s206, resetting the target winding machine and canceling the push cylinder completion signal.
By configuring the winder controller for each winder on the winder production line and the doffer controller for the doffer, the full-automatic doffing of the package spinning cake produced by each winder on the winder production line onto the doffer for conveying is realized, and the doffing and conveying efficiency of the spinning cake can be improved.

Otherwise, canceling the winding machine doffing call signal (Q3.1 is equal to 0) so as to enable the winding machine to enter a manual doffing mode; after receiving the doffing calling signal and giving an answer signal, the doffing machine moves to a winding machine which sends the doffing calling signal; after a lower clamping head of the winding machine stops running (zero speed), the winding machine gives a ready signal (Q3.2 is 1) of the winding machine to the doffer; after receiving the ready signal of the winding machine, the doffer positions a wire shaft of the doffer and a lower chuck of the winding machine, and after the positioning is finished, the doffer gives the ready signal of the doffer (Q0.2 is 1); the winding machine loosens the bobbin and pushes the bobbin after receiving the ready signal of the doffer; after the bobbin of the winding machine is in place, a bobbin pushing completion signal (Q3.3 is equal to 1) is given, and a bobbin falling calling signal (Q3.1 is equal to 0) and a winding machine ready signal (Q3.2 is equal to 0) are reset at the same time; after the push cylinder returns to the original position, the push cylinder completion signal is reset (Q3.3 is equal to 0), and the automatic cylinder dropping is completed.
