Description

Technical Field

[0001] The invention belongs to the technical field of drip irrigation tape production, in particular to a double-wheel automatic winding machine for a drip irrigation tape. Background Art

[0002] Drip irrigation is an advanced agricultural irrigation method that supplies water through a drip tape (or drip pipe) placed at the roots of crops. The drip tape has many small water outlets, and the water overflowing from the outlets slowly moistens the soil around the roots of the crops. After processing, the drip tape needs to be rolled up and packaged.

[0003] The double-wheel winder, such as patent announcement number CN106395464B, discloses an automatic winder for drip irrigation tape, which can realize automatic roll change in the production process of drip irrigation tape through two rotatable wheels. However, the winder in the patent still has the following problems:

[0004] 1. The patent adopts a method of fixing the reel with a detachable outer baffle and an inner baffle. After the reel is wound, the outer baffle needs to be removed manually, and a new empty reel needs to be installed and fixed after the full reel is removed, which makes the replacement of the empty reel more troublesome.

[0005] 2. The patent uses two winding motors to drive two winding wheels to rotate respectively. Due to the limitation of the cutting knife, the rotating arm assembly in the device can only drive the two winding motors to rotate in one direction. In order to prevent the wiring harness from being entangled, an electric slip ring needs to be set to power the two winding motors. However, this will undoubtedly increase the complexity of the circuit. When a circuit fails, it is difficult to determine the location of the fault.

[0060] How it works

[0061] When in use, the present invention needs to be used with a robot (not shown) to load the empty material tray. The present invention includes some structures that are partially the same as those in the patent with announcement number CN106395464B (such as the movable clamping plate, clamping cylinder, positioning clamping assembly, cutting knife, pipe control rod and wire arrangement device for arranging the drip irrigation tape in the patent). Its operating principles and effects are the same as those in the patent, so they are not repeated here. During use, the present invention controls the operation of each mechanism through a program set in the PLC controller 102.

[0062] like Figure 1-5 When the drip irrigation tape is wound up, the empty reel is fixed between the winding reel 203 and the clamping disc 304, and the servo motor 502 drives the driving sleeve 501 to rotate through the chain, so that the truss arm 201 rotates. When the truss arm 201 rotates, the driving sleeve 501 drives the cam plate 701 to rotate until the cam pin 704 moves to the tightening portion 7031 of the cam groove 703. Since the tightening portion 7031 is closer to the driving sleeve 501 than the other positions of the cam groove 703, the cam pin 704 is connected to the cam The rod 702 pulls the movable seat 602 toward the driving sleeve 501. When the movable seat 602 moves, it drives the driving shaft 603 and the driving gear 604 to approach the driving sleeve 501 until the driving gear 604 engages with the driven gear 204 located on the truss arm 201. Then, the servo motor 2 605 drives the driving shaft 603 and the driving gear 604 to rotate, and the driving gear 604 drives the driven gear 204 engaged therewith to rotate, and the driven gear 204 drives the winding shaft 202 and the winding disk 203 to rotate, so as to realize the winding of the drip irrigation tape.

[0063] like Figure 1-5 As shown, after the winding is completed, the servo motor 2 605 stops, and then the servo motor 1 502 drives the driving sleeve 501 and the truss arm 201 to rotate 180 degrees through the chain. During the rotation, the cam pin 704 pushes the movable seat 602 away from the driving sleeve 501 as the cam groove 703 rotates, thereby separating the driving gear 604 from the driven gear 204. After the cam pin 704 moves to the other tightening part 7031 of the cam groove 703, the driving gear 604 approaches the driving sleeve 501 again and meshes with the other driven gear 204. Then, the servo motor 2 605 is started again to rotate the other winding disk 203 to wind the drip irrigation tape.

[0064] like Figure 3 , 4As shown in Figure 7, after the truss arm 201 flips 180 degrees, the robot grabs the full reel, and then the servo motor 3 410 on the side away from the driving gear 604 is started and drives the threaded rod 401 to rotate, and the threaded rod 401 drives the semicircular movable plate 402 on the side away from the driving gear 604 to move away from the truss arm 201, and the semicircular movable plate 402 drives the clamping piece 405 on the side away from the driving gear 604 to move away from the truss arm 201 at the same time, so that the movable seat 303 drives the clamping disk 304 on the side away from the driving gear 604 to move away from the winding disk 203, and after the robot moves the full reel to the packaging station, it grabs a new empty reel and moves it between the clamping disk 304 and the winding disk 203, and then moves away from the driving gear The servo motor 3 410 on the 604 side is started again and drives the threaded rod 401 to rotate in the opposite direction, and the threaded rod 401 drives the semicircular movable plate 402 to move back to its original position. Position sensors are provided on the two semicircular movable plates 402, so that after the semicircular movable plate 402 returns to its original position, its surface can be parallel to the other semicircular movable plate 402, so that during the flipping of the truss arm 201, the two clamping parts 405 can rotate around the periphery of the circular plate formed by the two semicircular movable plates 402. After the clamping parts 405 move and drive the clamping disk 304 on the movable seat 303 to fix the empty reel, the manipulator is reset, and the unloading of the full reel and the loading of the empty reel can be carried out synchronously with the winding of the drip irrigation tape, thereby improving the efficiency of winding the drip irrigation tape.

[0065] like Figure 4-6 As shown, in the process of the moving seat 602 approaching the driving sleeve 501 to make the driving gear 604 mesh with the driven gear 204, the arc-shaped top plate 11 on the moving seat 602 pushes the roller 10 to move the arc-shaped stop plate 804 toward the driving sleeve 501, so as to achieve the effect of making the arc-shaped top plate 11 away from the driven gear 204. At this time, the arc-shaped stop plate 804 is separated from the driven gear 204 and does not affect the rotation of the driven gear 204. In the process of the truss boom 201 turning over, the moving seat 602 drives the arc top plate 11 away from the driving sleeve 501, and the arc stop plate 804 approaches the driven gear 204 under the elastic force of the spring 806. When the driven gear 204 rotates during the flipping process, it will be stuck in the stop groove 805, thereby limiting the rotation of the driven gear 204 and preventing the drip irrigation tape wound on the reel surface from loosening during the flipping of the truss arm 201. There are multiple stop grooves 805, which can effectively improve the locking effect of the arc stop plate 804 on the driven gear 204.

[0066] like Figure 4 , 7As shown, when replacing empty reels of different widths, first start the two servo motors 3 410, and the two servo motors 3 410 respectively drive the two threaded rods 401 to rotate, and the two threaded rods 401 respectively drive the two semicircular movable plates 402 to move, so that the two clamping disks 304 are respectively away from the two winding reels 203, and then the reels of the previous batch are removed, and then the robot grabs the empty reels of the new batch and moves them between the winding reel 203 and the clamping disk 304 away from the side of the driving gear 604, and first the servo motor 3 410 away from the side of the driving gear 604 is started and drives the winding reel 203 and the clamping disk 304 to fix the empty reel, and then the servo motor 3 410 close to the side of the driving gear 604 is started to drive the threaded rods 401 to move. The threaded rod 401 rotates, thereby adjusting the position of the semicircular movable plate 402 threadedly connected to the threaded rod 401, so that it is flush with the surface of the other semicircular movable plate 402, and then the servo motor 1 502 is started to drive the driving sleeve 501 to rotate, so that the truss arm 201 is flipped, and the empty reel is moved to a position close to the driving gear 604 to reel the drip irrigation tape. After the truss arm 201 is flipped 180 degrees, the servo motor 3 410 on the side away from the driving gear 604 is started again to rotate the clamping disk 304 on the side away from the driving gear 604 away from the winding reel 203, and then the manipulator grabs another empty reel and moves it between the winding reel 203 and the clamping disk 304, and the clamping disk 304 completes the fixation of the empty reel.
