Technical Field

[0001] This utility model relates to the field of plastic tray recognition and flipping technology, specifically a plastic tray front and back recognition and flipping device. Background Technology

[0002] Plastic pallets are widely used in logistics, warehousing and other industries. After the collected plastic pallets are placed on the conveyor mechanism by the feeding device, the plastic pallets on the conveyor mechanism can be either upright or upside down. In order to facilitate the direct use of the plastic pallets later, personnel are often arranged on the conveyor mechanism to find the upside-down plastic pallets and turn them over. Due to the large demand for plastic pallets and the fact that the plastic pallets have a certain weight, the manual identification and turning of plastic pallets puts a lot of work pressure on the staff and results in low work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a plastic tray front and back recognition and flipping device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The plastic tray front and back recognition and flipping device includes a conveyor belt, a mounting frame on the conveyor belt, a photoelectric sensor module on the mounting frame, a mounting platform on one side of the conveyor belt, a top plate above the mounting platform, a guide rod between the top plate and the mounting platform, a partition plate, guide cylinders at both ends of the partition plate, sleeves slidably connected to the guide rods on the outer surface of the guide cylinders, a first cylinder on the upper surface of the top plate, the output end of the first cylinder passing through the top plate and fixedly connected to the partition plate, a fixing plate, two crossbars slidably connected to the guide cylinders on one side of the fixing plate, a support groove on one side of the fixing plate and between the two crossbars, a motor inside the support groove, a movable plate on the side of the fixing plate, the output end of the motor passing through the fixing plate and fixedly connected to the movable plate, fork teeth at both ends of one side of the movable plate, a mounting plate between the two guide cylinders, a second cylinder on the mounting plate, the output end of the second cylinder fixedly connected to the support groove.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a plastic tray front / back recognition and flipping device includes a conveyor belt 1, a mounting frame 2 on the conveyor belt 1, a photoelectric sensor module 3 on the mounting frame 2, a mounting platform 4 on one side of the conveyor belt 1, a top plate 5 above the mounting platform 4, a guide rod 6 between the top plate 5 and the mounting platform 4, a partition 7, guide cylinders 8 at both ends of the partition 7, a sleeve 9 slidably connected to the guide rod 6 on the outer surface of the guide cylinder 8, a first cylinder 10 on the upper surface of the top plate 5, the output end of the first cylinder 10 passing through the top plate 5 and fixedly connected to the partition 7, and a fixed... A fixed plate 11 is provided. Two crossbars 12 are slidably connected to the guide cylinders 8 on one side of the fixed plate 11. A support groove 13 is provided on one side of the fixed plate 11 and between the two crossbars 12. A motor 14 is provided inside the support groove 13. A movable plate 15 is provided on the side of the fixed plate 11. The output end of the motor 14 passes through the fixed plate 11 and is fixedly connected to the movable plate 15. Fork teeth 16 are provided at both ends of one side of the movable plate 15. An installation plate 22 is provided between the two guide cylinders 8. A second cylinder 17 is provided on the installation plate 22. The output end of the second cylinder 17 is fixedly connected to the support groove 13.

[0018] The photoelectric sensor module 3 determines the orientation of the plastic tray 21 based on the intensity of reflected light. When the front of the plastic tray 21 is facing up, the intensity of reflected light is stronger, and when the back of the plastic tray 21 is facing up, the intensity of reflected light is weaker. The photoelectric sensor module 3 transmits the detected intensity signal of reflected light to the control mechanism PLC. The control mechanism PLC determines the orientation of the plastic tray 21 based on the signal. When the conveyor belt 1 transports the plastic tray 21 with the back facing up to one side of the mounting platform 4, the control mechanism PLC controls the conveyor belt 1 to stop running and then flips the plastic tray 21 so that the front of the plastic tray 21 is facing up.

[0019] When adjusting the orientation of the plastic support 21, the second cylinder 17 is first activated. The second cylinder 17 pushes the support groove 13 to move through its output end. The support groove 13 drives the motor 14 and the fixed plate 11 to move. Since the crossbar 12 and the guide cylinder 8 are slidably connected, the stability of the movement of the fixed plate 11 can be improved. When the two fork teeth 16 on the movable plate 15 on one side of the fixed plate 11 are inserted into the plastic support 21 a certain distance, the output end of the second cylinder 17 stops extending. Then the first cylinder 10 is activated, and the output end of the first cylinder 10 retracts. Through the partition 7, the two guide cylinders 8 are moved. Through the cooperation of the sleeve 9 and the guide rod 6, the stability of the guide cylinders 8 when moving up and down can be improved. When the guide cylinders 8 move upward with the partition 7, the fork teeth 16 and the plastic support 21 on the fork teeth 16 move upward synchronously. When the fork teeth 16 move upward a certain distance, the output end of the first cylinder 10 stops retracting. Then the motor 14 is activated, and the output of the motor 14... The output end drives the movable plate 15 and the fork 16 on the movable plate 15 to rotate 180°, and the plastic tray 21 located on the fork 16 also rotates 180°, thereby adjusting the plastic tray 21 from the reverse side facing up to the front side facing up. After the plastic tray 21 is adjusted, the motor 14 stops working, and then the first cylinder 10 drives the fork 16 and the plastic tray 21 to move downward until the plastic tray 21 is completely lowered onto the conveyor belt 1. When the plastic tray 21 is completely lowered onto the conveyor belt 1, the first cylinder 10 needs to drive the fork 16 to continue to descend a certain distance so that the fork 16 does not contact the plastic tray 21. When the fork 16 is in a state of not contacting the plastic tray 21, the first cylinder 10 stops working, and then the second cylinder 17 is started. The output end of the second cylinder 17 retracts, moving the fork 16 out of the plastic tray 21. Then the conveyor belt 1 continues to work and transport the plastic tray 21. When the fork 16 is reset, the second cylinder 17 stops working to facilitate the subsequent flipping of the plastic tray 21.

[0020] Furthermore, a through groove is provided on the mounting plate 22, and a fixed cylinder 18 is provided inside the through groove. The second cylinder 17 is located inside the fixed cylinder 18. The stability of the second cylinder 17 can be improved by the fixed cylinder 18.

[0021] Furthermore, a reinforcing cylinder 19 is provided on the upper surface of the top plate 5, and the first cylinder 10 is located inside the reinforcing cylinder 19. The reinforcing cylinder 19 can improve the stability of the first cylinder 10.

[0022] Furthermore, a stop block 20 is provided at the end of the crossbar 12 away from the fixed plate 11, which helps to confine the crossbar 12 inside the guide cylinder 8 and prevent the crossbar 12 from separating from the guide cylinder 8.

[0023] Furthermore, when the movable plate 15 is stationary, the two fork teeth 16 on the movable plate 15 are at the same horizontal height. The shortest distance between the fork teeth 16 and the upper surface of the mounting platform 4 when stationary is equal to the shortest distance between the fork teeth 16 and the upper surface of the mounting platform 4 after the motor 14 drives the movable plate 15 to rotate 180°. After the fork teeth 16 complete the adjustment and reset of the plastic support 21, the height and position of the reset fork teeth 16 are always fixed and do not require additional adjustment, such as forward or reverse adjustment, thereby improving the convenience of use.
