Description

Technical Field

[0001] The invention relates to an automatic reel-changing device and method for an enameling machine wire take-up, belonging to the technical field of enameled wire production. Background Art

[0002] When a traditional enameled production line takes up the wire on a take-up reel, the wire needs to be manually threaded to the wire entry incision position of the take-up reel. After the wire end is manually threaded, the take-up reel is started, and the take-up reel rotates to take up the wire. After the wire has been wound to the set number of meters, a dedicated operator needs to manually wrap a protective film around the enameled wire to protect it. The enameled wire and the protective film are then manually cut off, and the take-up reel stops rotating to complete the wire winding and coating operations. When it is necessary to change the reel, the enameled wire needs to be manually pulled onto another empty take-up reel to be used, and the wire end needs to be manually threaded again. After confirming that the wire end is threaded, the take-up reel is started, and the above-mentioned wire winding and coating operations are repeated. The existing technology is relatively simple in structure and has low manufacturing costs. However, manual operation by the operator is labor-intensive and has low production efficiency, which is particularly evident for high-speed enameling machines.

[0003] In order to adapt to the high-speed production of the production line, improve production efficiency and reduce the labor intensity of workers, the field urgently needs to propose an automatic reel-changing device and method for enameling machine wire taking-up that can automatically recognize wires, automatically change reels and automatically coat films.

The intelligent controller is a well-known and commonly used technology in the art, such as a single-chip microcomputer, PLC, and host computer. The structures of the first and second take-up reels are the same as those of conventional take-up reels.

[0019] A method for automatically changing reels for taking up wires of an enameling machine is provided, which is performed using the above-mentioned automatic reel-changing device for taking up wires of an enameling machine, and the steps are as follows:

[0020] ①Put the enameled flat wire into the intelligent machine head, the intelligent machine head moves to the set position on the left, the intelligent machine head automatically captures the wire entry incision position of the take-up reel 1, the intelligent machine head swings to the left to the set position, and the driving motors of the two crawler traction mechanisms of the intelligent machine head rotate synchronously. The crawlers of the two crawler traction mechanisms simultaneously pull the enameled flat wire to the wire entry incision position of the take-up reel 1 and feed the set length of enameled flat wire. After the wire recognition device 1 on the wire entry incision position of the take-up reel 1 confirms the successful recognition of the wire, the take-up reel 1 is started, the take-up reel 1 rotates, and the enameled flat wire is fixed at the incision position and wound normally; at the same time, the intelligent machine head is linked, and the intelligent machine head returns to the winding working position at a reasonable speed and posture; after the wire is taken up to the set number of meters, the take-up reel 1 continues to rotate, and the pressure wheel 1 of the coating component 1 rotates with the swing arm 1 around the support shaft 1 under the drive of the cylinder 1, The pressure wheel presses the protective film against the take-up reel, and the film blowing device starts to blow the protective film toward the take-up reel. The protective film falls off the film blowing device and is placed on the take-up reel. The cylinder drives the pressure wheel to stick the protective film to the outer surface of the enameled flat wire on the take-up reel. After coating with several layers of protective film, the take-up reel stops rotating, completing the film coating operation of the left take-up reel. The protective film is cut off by a manual or electric shearing device, and then the protective film is set to a place on the film blowing device. The take-up reel is removed after winding up, and waits for the next coating operation.

[0021] ② After the wire lamination of the left take-up reel 1 is completed, the intelligent machine head moves to the set position on the right, and the intelligent machine head automatically captures the wire entry incision position of the take-up reel 2. The intelligent machine head swings to the right to the set position, and the driving motors of the two crawler-type traction mechanisms of the intelligent machine head rotate synchronously. The crawlers of the two crawler-type traction mechanisms simultaneously pull the enameled flat wire to the wire entry incision position of the take-up reel 2, and feed the enameled flat wire of the set length. After the wire recognition device 2 on the wire entry incision position of the take-up reel 2 confirms the successful recognition of the wire, it starts the take-up reel 2, and the take-up reel 2 rotates. The enameled flat wire is fixed at the incision position and then wound normally; at the same time, the intelligent machine head is linked and returns to the winding work position at a reasonable speed and posture; After the wire is taken up to the set number of meters, the take-up reel 2 continues to rotate, and the pressure wheel 2 of the film coating component 2 rotates along with the swing arm 2 around the support shaft 2 under the drive of the cylinder 2. The pressure wheel 2 presses the protective film 2 toward the take-up reel 2, and the film blowing device 2 starts to blow the protective film 2 toward the take-up reel 2. The protective film 2 falls off the film blowing device 2 and is transferred to the take-up reel 2. The cylinder 2 drives the pressure wheel 2 to attach the protective film 2 to the outer surface of the enameled flat wire on the take-up reel 2. After coating several layers of protective film 2, the take-up reel 2 stops rotating, completing the wire coating of the take-up reel 2 on the right side. The protective film 2 is cut off by a manual or electric shearing device, and then the protective film 2 is set to the film blowing device 2. The take-up reel 2 after taking up the wire is removed and waits for the next coating operation.

[0022] ③ Repeat steps ① and ② to complete the reel changing, take-up and laminating operations.

[0023] Furthermore, before each wire winding and lamination, it is necessary to cut the enameled flat wire to take a sample line. The intelligent machine head moves to above the opening of the sample collection tube, and the drive motors of the two crawler traction mechanisms rotate synchronously. The tracks of the two crawler traction mechanisms simultaneously pull the enameled flat wire into the sample collection tube. When the wire cutting drive cylinder is actuated, the wire cutting top block 1 and the wire cutting top block 2 are driven to move simultaneously. The wire cutting top block 1 and the wire cutting top block 2 push the wire cutting block 1 and the wire cutting block 2 to move relative horizontally, and the enameled flat wire is cut at the shearing position. The cut enameled flat wire falls into the sample collection tube, and the cut sample wire is manually taken out for inspection to check whether the enameled flat wire is qualified.

[0024] The positive effects of the present invention are as follows: the wire take-up machine of the enameled production line can realize automatic wire recognition, wire breaking, reel replacement and film coating during wire take-up, thereby effectively improving work efficiency and reducing labor costs.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] Combined with attachment Figure 1-3 This embodiment provides an automatic reel-changing device for an enameling machine, comprising a reel-1 4 and a reel-2 9 that are rotatably mounted on a reel frame 1. The reel frame 1 is a rectangular frame structure, with a traction guide wheel 7 provided on the outer side of the upper crossbeam of the reel frame 1, a laminating assembly 3 provided on the left side of the reel-1 4, and a laminating assembly 2 10 provided on the right side of the reel-2 9; a transverse movable guide rail pair 6 is fixedly mounted on the inner side of the upper crossbeam of the reel frame 1, and a longitudinal movable guide rail pair 8 is mounted on a transverse movable guide rail slider on the transverse movable guide rail pair 6. The longitudinal movable guide rail pair 8 can reciprocate left and right along the transverse movable guide rail pair 6. The intelligent machine head 5 is mounted on the longitudinal movable guide rail pair 8 via a swing mechanism, can move up and down along the longitudinal movable guide rail pair 8, and can swing left and right according to the reel position.

[0035] The intelligent machine head 5 is composed of a wire holding and traction device 14 and a wire cutting device 13 arranged above and below. The enameled rectangular wire 31 outside the wire take-up frame 1 is turned by the traction guide wheel 7 and then extends into the wire holding and traction device 14 and the wire cutting device 13. The wire gripping and pulling device 14 is used to clamp and pull the enameled flat wire 31 to the wire entry incision position of the wire take-up reel 1 4 or the wire take-up reel 2 9. The wire entry incision positions of the wire take-up reel 1 4 and the wire take-up reel 2 9 are respectively provided with a wire recognition device 1 and a wire recognition device 2. The wire recognition device 1 and the wire recognition device 2 are used to confirm whether the enameled flat wire 31 enters the wire entry incision position and whether the length of the enameled flat wire 31 fed in reaches the preset length. The wire take-up reel 1 4 and the wire take-up reel 2 9 are used to take up the enameled flat wire 31. The coating component 1 3 and the coating component 2 10 are used to coat the enameled flat wire 31 after winding. The wire cutting device 13 is used to shear the enameled flat wire 31 after coating. The cut enameled flat wire 31 is also clamped by the mobile head 5. The mobile head 5 carries the enameled flat wire 31 to the other side for winding and coating of another empty wire take-up reel.

[0036] Before each winding, it is necessary to cut the sample line of the enameled flat wire 31, so a sample collecting tube 12 is set between the winding reel 1 4 and the winding reel 2 9. The sample collecting tube 12 is an L-shaped tube. The intelligent head 5 moves to the top of the opening of the sample collecting tube 12, and the driving motors 16 of the two crawler traction mechanisms 15 rotate synchronously. The crawlers of the two crawler traction mechanisms 15 simultaneously pull the enameled flat wire 31 into the sample collecting tube 12. When the wire cutting drive cylinder 25 is actuated, the wire cutting top block 1 23 and the wire cutting top block 2 38 are driven to move synchronously. The wire cutting top block 1 23 and the wire cutting top block 2 38 push the wire cutting block 1 22 and the wire cutting block 2 37 to move relative horizontally, and the enameled flat wire 31 is cut at the shearing position. The cut enameled flat wire 31 falls into the sample collecting tube 12.

[0037] Combined with attachment Figure 4In this embodiment, the wire gripping traction device 14 includes a crawler traction mechanism 15, a drive motor 16, a fixed connecting plate 17, a double-link mechanism 18, a clamping cylinder 19 and a base 11. The base 11 is arranged on the longitudinal movable guide rail pair 8 through a swing mechanism. The swing mechanism drives the base 11 to swing left and right, and the swing mechanism slides up and down on the longitudinal movable guide rail pair 8; a clamping cylinder 19 is provided on the base 11, and there are two crawler traction mechanisms 15, which are respectively installed on the two fixed connecting plates 17 arranged on the left and right. The enameled flat wire 31 passes between the two crawler traction mechanisms 15, and the two fixed connecting plates 17 are hinged to the base 11 and the lever of the clamping cylinder 19 through their respective double-link mechanisms 18; the lever action of the clamping cylinder 19 drives the two double-link mechanisms 18 to drive the corresponding crawler traction mechanisms 15 to clamp the enameled flat wire 31, and the drive motors 16 of the two crawler traction mechanisms 15 rotate synchronously, and the crawlers of the two crawler traction mechanisms 15 simultaneously pull the enameled flat wire 31 to move, thereby realizing the traction and transportation of the enameled flat wire 31.

The intelligent controller controls the movement and swing of the intelligent machine head, automatically searches for the line entry incision position, and starts the crawler traction mechanism after moving to the set position. The enameled flat wire is a relatively stiff material. The enameled flat wire between the intelligent machine head 5 and the take-up reel 1 4 or the take-up reel 2 9 is in a straight line, so the crawler traction mechanism 15 can directly feed the enameled flat wire 31 into the line entry incision position and feed the set length of enameled flat wire. The camera transmits the image information of the line entry incision position to the intelligent controller. After the intelligent controller confirms that the line is successfully identified, the intelligent controller controls the take-up reel 1 to start and rotate. The enameled flat wire is normally wound after the incision position is fixed. When the wire is wound to the set length, the intelligent controller controls the take-up reel 1 to stop. Preferably, an alarm device can also be provided. When the enameled flat wire is not accurately fed into the wire incision position or the feeding length does not reach the preset value, the camera transmits the image information to the intelligent controller, and the intelligent controller controls the alarm device to emit a warning sound, etc., at which time the wire take-up reel stops moving.

[0041] Preferably, the swing mechanism is a motor, the output shaft of the motor is connected to the base 11, the motor is arranged in a housing, and the housing is slidably arranged on the longitudinal movable guide rail pair 8.

A second buffer spring 39 is provided between the second trimming block mounting plate 35 and the fixed plate 36. The second trimming block mounting plate 35 is connected to the output shaft 2 of the trimming drive cylinder 25 through the second trimming top block 38.

[0046] A space is left between the blade ends of shearing block 1 (22) of shearing mechanism 1 and shearing block 2 (37) of shearing mechanism 2 for the enameled flat wire 31 to pass through, forming a shearing notch through which the enameled flat wire 31 extends. When the lever of the clamping cylinder 19 is actuated, driving the two fixed connecting plates 17 to open, shearing mechanisms 1 and 2 also open, widening the shearing notch. When the lever of the clamping cylinder 19 is actuated, driving the two fixed connecting plates 17 to close, shearing mechanisms 1 and 2 also close, narrowing the shearing notch. When the enameled flat wire 31 needs to be sheared, the shearing drive cylinder 25 actuates, synchronously driving shearing block 1 (23) and shearing block 2 (38) according to the command to set the length of the enameled flat wire 31.

The other end is arranged on the film blowing device 2 44, and the air outlet of the film blowing device 2 44 is directed toward the protective film 2 45; the lever of the cylinder 2 42 is connected to the swing arm 2 46, and the swing arm 2 46 is rotatably arranged on the support shaft 2 41. The end of the swing arm 2 46 is provided with a pressure wheel 2 43. The action of the cylinder 2 42 drives the swing arm 2 46 to rotate along the support shaft 2 41, and the film blowing device 2 44 blows air toward the protective film 2 45, so that the protective film 2 45 falls off from the film blowing device 2 44, and the pressure wheel 2 43 presses down the protective film 2 45 between the film blowing device 2 44 and the film unwinding shaft 2 40, and presses the protective film 2 45 to the outside of the enameled flat wire 31 on the take-up reel 2 9.

[0049] A method for automatically changing the reel of an enameling machine is provided, which is performed using the above-mentioned automatic reel-changing device for enameling machine, and the specific steps are as follows:

[0050] ① The pressing cylinder 19 of the intelligent machine head 5 is actuated, driving the two fixed connecting plates 17 to open, and the shearing mechanism 1 and the shearing mechanism 2 are also opened, the shearing opening becomes larger, and the end of the enameled flat wire 31 passes through the shearing opening and extends out of the mobile machine head 5. The pressing cylinder 19 is actuated, driving the two fixed connecting plates 17 to close, clamping the enameled flat wire 31; the driving motors 16 of the two crawler-type traction mechanisms 15 rotate synchronously, and the crawlers pull the enameled flat wire 31 into motion;

[0051] ② Before each winding, the enameled flat wire 31 needs to be cut to take a sample. The intelligent machine head 5 moves to the top of the opening of the sample collection tube 12, and the driving motors 16 of the two crawler traction mechanisms 15 rotate synchronously. The crawlers of the two crawler traction mechanisms 15 simultaneously pull the enameled flat wire 31 into the sample collection tube 12. After the sampling length reaches the set requirement, according to the instructions of the intelligent controller, the wire cutting drive cylinder 25 is actuated to synchronously drive the wire cutting top block 1 23 and the wire cutting top block 2 38 to move. The wire cutting top block 1 23 and the wire cutting top block 2 38 push the wire cutting block 1 22 and the wire cutting block 2 37 to move horizontally relative to each other, and the enameled flat wire 31 is cut at the shearing position. The cut enameled flat wire 31 falls into the sample collection tube 12.

[0052] ③ The intelligent machine head 5 moves to the set position on the left, and the intelligent machine head 5 automatically captures the wire entry incision position of the take-up reel 4. The intelligent machine head 5 swings to the left to the set position, and the driving motors 16 of the two crawler traction mechanisms 15 of the intelligent machine head 5 rotate synchronously. The crawlers of the two crawler traction mechanisms 15 simultaneously pull the enameled flat wire 31 to the wire entry incision position of the take-up reel 4, and feed the enameled flat wire 31 of the set length. After confirming that the wire is successfully recognized, the wire recognition device on the wire entry incision position of the take-up reel 4 starts the take-up reel 4, and the take-up reel 4 rotates. The enameled flat wire 31 is wound normally after being fixed at the incision position; at the same time, the intelligent machine head 5 is linked, and the intelligent machine head returns to the winding work position at a reasonable speed and posture. After the wire has been taken up to the set number of meters, the take-up reel 4 continues to rotate, and the pressure wheel 28 of the film coating assembly 3 rotates around the support shaft 26 along with the swing arm 34 under the drive of the cylinder 27. The pressure wheel 28 presses the protective film 30 against the take-up reel 4, and the film blowing device 29 starts to blow the protective film 30 toward the take-up reel 4. The protective film 30 falls off the film blowing device 29 and onto the take-up reel 4. The cylinder 27 drives the pressure wheel 28 to attach the protective film 30 to the outer surface of the enameled rectangular wire 31 on the take-up reel 4. After coating with several layers (the number of layers can be set) of protective film 30, the take-up reel 4 stops rotating, completing the take-up and coating operation of the left take-up reel 4. The protective film 30 is cut off by a manual or electric shearing device, and then the protective film 30 is set to the film blowing device 29. The take-up reel 4 after the wire is taken up is removed and waits for the next coating operation.

[0053] ④ After the wire coating of the left wire reel 4 is completed, the reel needs to be changed. First, the intelligent head 5 moves to the sample wire cutting position to carry out the sample wire cutting process. After the sample wire cutting is completed, the intelligent controller controls the intelligent head 5 to move to the set position on the right. The intelligent head 5 automatically captures the wire entry incision position of the wire reel 2 9. The intelligent head 5 swings to the right to the set position. The driving motors 16 of the two crawler traction mechanisms 15 of the intelligent head 5 rotate synchronously. The crawlers of the two crawler traction mechanisms 15 simultaneously pull the enameled flat wire 31 to the wire entry incision position of the wire reel 2 9 and feed in the set length of the enameled flat wire 31. After confirming that the wire is successfully recognized, the wire recognition device 2 on the wire entry incision position of the wire reel 2 9 starts the wire reel 2 9, and the wire reel 2 9 rotates. The enameled flat wire 31 is wound normally after the incision position is fixed; at the same time, the moving head 5 is linked, and the head returns to the winding working position at a reasonable speed and posture. After the wire is taken up to the set number of meters, the wire take-up reel 29 continues to rotate, and the pressure wheel 243 of the film coating assembly 210 rotates with the swing arm 246 around the support shaft 241 under the drive of the cylinder 242, and the pressure wheel 243 presses the protective film 245 toward the wire take-up reel 29, and the film blowing device 244 starts to blow the protective film 245 toward the wire take-up reel 29, and the protective film 245 falls off from the film blowing device 244 to the wire take-up reel 29, and the cylinder 242 drives the pressure wheel 243 to attach the protective film 245 to the outer surface of the enameled flat wire 31 on the wire take-up reel 29. After coating several layers (the number of layers can be set) of the protective film 245, the wire take-up reel 29 stops rotating, completing the wire coating of the right wire take-up reel 29, and cutting the protective film 245 by a manual or electric shearing device, and then setting the protective film 245 to the film blowing device 244. The wire take-up reel 29 after taking up the wire is removed and waits for the next coating operation.

[0054] The present invention, through a series of actions of the intelligent machine head, laminating components, etc., can automatically complete the processes of wire gripping and pulling, wire identification through incision, wire identification, winding, laminating, wire cutting, wire sample cutting, reel movement, etc. after reaching the set number of meters, thereby completing automatic reel change and automatic laminating. Finally, it is only necessary to manually remove the reel after the laminating and winding is completed, put down a new empty reel, and reinstall one end of the cut protective film on the film blowing device. This solves the problem that the original reel change of the wire take-up machine can only be completed manually through the processes of reel change, wire identification, and laminating, and realizes automated production. It greatly improves the working efficiency of the enameled production line equipment, reduces the labor intensity of enameled wire production, accelerates and promotes the technological progress of the enameled production line equipment, and lays the foundation for the subsequent intelligent development of enameled production line equipment.
