Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the wheel unloading control device of the stranding machine comprises a take-up spool 2, a telescopic cylinder 3, an electromagnetic valve 4, an electrical transfer switch 5 and a machine tool control system PLC6, wherein the electromagnetic valve 4 is connected with the telescopic cylinder 3, the electromagnetic valve 4 and the electrical transfer switch 5 are respectively connected with the machine tool control system PLC, when the electrical transfer switch 5 is started, the machine tool control system PLC judges whether a preset condition is met, if the preset condition is met, the electromagnetic valve 4 is controlled to be switched on, the telescopic cylinder 3 retracts, and the take-up spool 2 can be detached from a machine tool 10 of the stranding machine.

In a preferred embodiment, a meter counting device (not shown) is arranged on the machine tool 10, and is connected with a machine tool control system PLC6, and the meter counting device calculates the actual meter number of the steel cord wound by the take-up spool through the machine tool control system PLC; the machine tool control system PLC6 judges whether the actual meter number meets the preset condition through the acquired actual meter number of the steel cord at the take-up side, and when the preset condition is met, the machine tool control system PLC6 controls the electromagnetic valve 4 to be conducted. After the electromagnetic valve 4 is switched on, the piston of the telescopic cylinder 3 retracts, so that the wire take-up spool 2 can be detached from the machine tool 10.

In a preferred embodiment, the telescopic cylinder 3 is fixed on the machine tool 10 and disposed at one side of the wire take-up spool 2, and when the electromagnetic valve 4 is in an unpowered state, a piston of the telescopic cylinder 3 extends out and presses against one side of the wire take-up spool 2.

In addition, a rotating part is arranged at the joint of the piston and the wire take-up spool 2, and the rotating part can rotate along with the rotation of the wire take-up spool 2, so that the piston of the telescopic cylinder 3 is tightly pressed and connected with the wire take-up spool 2, and the rotation of the wire take-up spool 2 around the transmission shaft 1 is not influenced.

The transmission shaft 1 is arranged on the machine tool 10, and the take-up spool 2 is sleeved on the transmission shaft 1.

The wheel unloading control device of the strander further comprises a key switch (not shown), the key switch is connected to a PLC of a machine tool control system, the key switch can be forcibly conducted with an electromagnetic valve 4 connected with a telescopic cylinder 3 through PLC program execution, the telescopic cylinder 3 retracts, and the take-up spool 2 can be detached from the machine tool.

It should be noted that, when the key switch is used, the machine tool control system PLC directly goes beyond the step of determining whether the actual number of meters meets the preset condition, that is, after the key switch is started, the electromagnetic valve 4 is forcibly powered on by changing the condition of program execution in the machine tool control system PLC. The key switch is to avoid the problem that the wire-receiving spool 2 cannot be disassembled when the wire-receiving spool needs to be disassembled forcibly.

As shown in fig. 2, the present invention further provides a control method 100 for wheel unloading of a strander, the control method 100 comprising:

s0, starting an electrical change-over switch;

s1, judging whether the actual meter number of the steel cord wound by the take-up spool meets a preset condition;

s2, if the preset condition is met, controlling the electromagnetic valve to be conducted;

s3, disassembling the wire take-up spool.

In a preferred embodiment, before the step S1 of determining whether the actual number of meters of the steel cord wound by the take-up spool meets the preset condition, the step S0 is further included, the electrical switch 5 is turned on, and a request signal for detaching the take-up spool 2 is output to the machine tool control system PLC 6.

In addition, after receiving the request signal, the machine tool control system PLC6 determines whether the actual number of meters satisfies a preset condition. The actual number of meters is calculated by the machine control system PLC6 from the pulse signals of the meter device on the machine tool 10.

In a preferred embodiment of the present invention, when the machine tool control system PLC6 determines that the actual number of meters meets the preset condition, it sends a prompt signal to prompt the operator to turn on the electrical transfer switch 5, and after the electrical transfer switch 5 is turned on, the machine tool control system PLC6 controls the electromagnetic valve 4 to be turned on, the telescopic cylinder 3 retracts, and the wire-rewinding spool is dismounted.

The prompt signal includes but is not limited to a text prompt or a voice prompt or a combination of text and voice prompts.

In addition, when the machine tool control system PLC6 determines that the preset condition is not satisfied, the solenoid valve 4 remains in the original state and does not operate, and the take-up spool 2 cannot be detached from the take-up machine on the machine tool 10.

The step of controlling the electromagnetic valve to be conducted in S2 further includes: the piston of the telescopic cylinder 3 is retracted.

Compared with the prior art, the wheel unloading control device and the control method of the stranding machine control system control the conduction of the electromagnetic valve through the machine tool control system PLC to control the retraction of the telescopic cylinder connected with the electromagnetic valve, solve the problem that an operator of the stranding machine mistakenly takes a semi-finished steel cord with insufficient take-up length as a finished product to unload a wheel, ensure the product quality stability of the finished steel cord and reduce the feedback of an external user.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. Furthermore, the technical features mentioned in the different embodiments of the present invention described above may be combined with each other as long as they do not conflict with each other. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, modifications and adaptations of the present invention are within the scope and spirit of the present invention.
