Description

Technical Field

[0001] The present invention relates to a pay-off mechanism for spools, and more particularly to a double-wheel pay-off automatic switching device and method thereof. Background Art

[0002] When electroplating a steel wire, there will be a pay-off end and a take-up end. The pay-off end is to pay off the steel wire to be electroplated from the spool, and the take-up end is to rewind the electroplated steel wire onto a new spool. For the pay-off end of the steel wire, a lot of manual participation was required before. Before the end of the steel wire pay-off, workers had to stand on the site in advance. Once the pay-off was completed, manual switching between the empty spool and the full spool after pay-off was required. If the workers were negligent and forgot to switch in time, wire breakage would occur, greatly affecting the production quality and efficiency, and also consuming a great deal of labor. Summary of the Invention

[0003] In order to solve the problem that untimely switching of the steel wire pay-off leads to wire breakage, affecting production quality and efficiency, the present invention provides a double-wheel pay-off automatic switching device and method to solve this problem.

[0004] The double-wheel pay-off automatic switching device of the present invention includes a frame, a fixed wheel system, a movable device and a switching device. The fixed wheel system is installed below the top of the frame. The movable device is arranged below the fixed wheel system. The movable device includes a rocker arm and a mounting bracket. One end of the rocker arm is fixedly connected to the frame, and the other end is fixedly connected to the mounting bracket. The mounting bracket is provided with a first wire-passing wheel, an encoder and an induction switch for sensing whether the first wire-passing wheel is working. Below one side of the rocker arm away from the frame, there is a rotary wire-pulling mechanism for peeling the steel wire from the spool. The rotary wire-pulling mechanism has a bearing seat, a bearing and a hollow wire-passing rotating shaft arranged in the bearing. The rotary wire-pulling mechanism is sleeved on the rocker arm through the bearing seat. The fixed part of the encoder is fixedly connected to the mounting bracket, and the rotating part of the encoder is connected to the hollow wire-passing rotating shaft. The switching device is a cylinder. The cylinder body of the cylinder is fixedly connected to the frame, and the extending end of the cylinder is hinged to the rocker arm. The rocker arm can be driven by the cylinder to switch back and forth above the first spool station and above the second spool station.

[0005] Further, specifically, the fixed wheel system includes a wire-passing drum, a circular mounting plate and a plurality of second wire-passing wheels circumferentially arranged on the circular mounting plate. The wire-passing drum is installed on the frame, and the circular mounting plate is also installed on the frame. The wrap angle formed by the plurality of second wire-passing wheels should simultaneously meet the wire-passing requirements for pay-off from the first spool and pay-off from the second spool, and the smaller the distance between the second wire-passing wheels, the better. The smaller the distance, the smoother and straighter the steel wire during the pay-off process.

[0006] Furthermore, specifically, it also includes a PLC control system, and the encoder and the induction switch are both electrically connected to the PLC control system.

[0007] A control method for a double-wheel pay-off automatic switching device,

[0008] a. The first spool is placed on the first spool station, and the second spool is placed on the second spool station. Assuming that the first spool is laying out wire, and the second spool is a spool with full wire waiting to be laid out, the end of the rotating wire-drawing mechanism rotates around the first spool to draw wire. The worker can connect the end of the steel wire on the first spool with the beginning of the steel wire on the second spool at any time before the first spool finishes laying out wire;

[0009] b. When the wire pay-off on the first spool wheel is finished, the rotating wire-drawing mechanism stops rotating, and the encoder transmits this signal to the PLC control system. At the same time, the induction switch senses that the first wire-passing wheel is still rotating, and also transmits the signal to the PLC control system. The output end of the PLC control system sends an execution signal, and the extended end of the cylinder moves to push the rocker arm from the first spool wheel position to the second spool wheel position to continue to pay off the wire on the second spool wheel;

[0010] c. The worker can fork the first spool after the wire laying is completed at any time before the second spool is finished, and place the new first spool with full wire on the first spool position, and connect the end of the steel wire of the second spool with the beginning of the steel wire of the new first spool with full wire, and repeat the wire laying work over and over again;

[0011] d. When the rotary wire pulling mechanism is rotating, the first wire passing wheel is also rotating, and the cylinder does not move; when the rotary wire pulling mechanism is not rotating, the first wire passing wheel is not rotating, and the cylinder does not move.

[0012] The invention has the following beneficial effects: during the wire-laying process, when the I-shaped wheel on one station finishes laying the wire, the PLC control system pushes the rocker arm to the full-line I-shaped wheel on another station to continue laying the wire through the monitoring and control cylinder, and repeats this process. The labor intensity of the workers is greatly reduced, and the product quality and production efficiency are improved; more importantly, the whole process reserves a long operation time for the workers, and it is not easy for the workers to break the wire due to negligence and forgetfulness, thereby affecting the product quality and efficiency.

Below one side of the rocker arm 2 away from the frame 1, there is a rotary wire-pulling mechanism 7 for peeling the steel wire from the spool. The rotary wire-pulling mechanism 7 has a bearing seat 14, a bearing 15, and a hollow wire-passing rotating shaft 16 arranged in the bearing 15. The rotary wire-pulling mechanism 7 is sleeved on the rocker arm 2 through the bearing seat 14, and the bearing 15 is fixed on one side of the bearing seat 14. The fixed part of the encoder 5 is fixedly connected to the mounting bracket 3, and the rotating part of the encoder 5 is connected to the hollow wire-passing rotating shaft 16.

[0026] A control method for an automatic double-wheel wire-releasing switching device

[0027] a. A first spool is placed on the first spool station 12, and a second spool is placed on the second spool station 13. Assume that the first spool is releasing wire, and the second spool is a full-line spool waiting to release wire. The end of the rotary wire-pulling mechanism 7 rotates around the first spool to pull the wire. The worker can connect the end of the steel wire on the first spool to the beginning of the steel wire on the second spool at any time before the first spool finishes releasing wire.

[0028] b. When the wire release on the first spool ends, the rotary wire-pulling mechanism 7 stops rotating. The encoder 5 feeds back this signal to the PLC control system. At the same time, the induction switch 6 senses that the first wire-passing wheel 4 is still rotating and also feeds back the signal to the PLC control system. The output end of the PLC control system issues an execution signal, and the extending end of the cylinder 8 acts to push the rocker arm 2 from above the first spool station 12 to above the second spool station 13 to continue releasing wire for the second spool.

[0029] c. The worker can remove the first spool after the wire pay-off is completed at any time before the second spool finishes wire pay-off, place the new full-line first spool on the first spool station 12, connect the end of the steel wire of the second spool to the start of the steel wire of the new full-line first spool, and carry out the wire pay-off work in a cycle.

[0030] d. When the rotary wire pulling mechanism 7 is rotating and working, the first wire passing wheel 4 is also rotating and working, and the cylinder 8 does not act. When the rotary wire pulling mechanism 7 is not rotating and working, the first wire passing wheel 4 is not rotating and working either, and the cylinder 8 does not act.

[0031] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
