Description

Technical Field

[0001] This disclosure pertains to the field of logistics sorting, specifically relating to an integrated dynamic weighing and sorting device for logistics and its usage method. Background Technology

[0002] With the continuous development of technology, during the production and packaging process, it is necessary to weigh the packaged products to identify defective ones. Currently, weighing devices are commonly used on factory production lines, and defective products are then manually removed. However, existing technology cannot seamlessly integrate with current production lines, resulting in low automation and low efficiency. Summary of the Invention

[0003] The purpose of this disclosure is to provide an integrated dynamic weighing and sorting device for logistics.

[0004] The objective of this disclosure can be achieved through the following technical solutions:

[0005] An integrated dynamic weighing and sorting device for logistics includes a base plate. A first conveyor and a second conveyor are placed parallel to each other on the base plate, with the end of the first conveyor close to the beginning of the second conveyor. The height of the upper surface of the first conveyor is higher than that of the upper surface of the second conveyor. A support plate is provided at the position where the first and second conveyors are close to each other. A telescopic component is fixed to the lower surface of the support plate. The lower end of the telescopic component is fixed to the base plate. A spring is placed coaxially on the telescopic section of the telescopic component. The upper end of the spring is fixed to the support plate, and the lower end of the spring is fixed to the upper end of the fixed section of the telescopic component.

[0006] The first conveyor has a fixed stop bar at its end, with one end of the stop bar extending directly above the pallet.

[0007] The first support plate is fixed on the end side wall of the second conveyor. The first support plate is provided with a first screw that is rotatably connected. One end of the first screw extends toward the end of the support plate. A push shaft that is threadedly connected is fitted on the first screw. A pair of first sliding grooves that are symmetrically placed on the periphery of the push shaft are opened.

[0008] A rectangular frame is fixed on one side of the support plate, through which the push shaft can pass. A pair of symmetrically placed support bars are fixed on the side of the rectangular frame near the first support plate. Card plates are fixed on the sides of the two support bars that are close to each other. Both card plates can be inserted into the first slide groove and can slide along the first slide groove.

[0009] When no object is placed on the pallet, the lower plate is located in the lower first slide groove, and the upper plate is located directly above the upper first slide groove. There is a gap between the upper plate and the upper peripheral wall of the push shaft, and this gap is greater than the depth to which the lower plate is inserted into the first slide groove.

[0010] The beneficial effects of this disclosure are:

[0011] This invention sorts and discharges express boxes that are underweight or exceed the standard range, improving the automation of weighing and sorting and increasing work efficiency. Attached Figure Description

[0019] like Figures 1 to 7 As shown, an integrated dynamic weighing and sorting device for logistics includes a base plate 1. A first conveyor 2 and a second conveyor 3 are arranged in parallel on the base plate 1. The end of the first conveyor 2 is close to the beginning of the second conveyor 3. The height of the upper surface of the first conveyor 2 is higher than the height of the upper surface of the second conveyor 3. A support plate 4 is provided at the position where the first conveyor 2 and the second conveyor 3 are close to each other. A telescopic member 41 is fixed to the lower surface of the support plate 4. The lower end of the telescopic member 41 is fixed to the base plate 1. A spring 42 is placed on the telescopic section of the telescopic member 41 and is placed on the same axis. The upper end of the spring 42 is fixed to the support plate 4, and the lower end of the spring 42 is fixed to the upper end of the fixed section of the telescopic member 41.

[0020] The end of the first conveyor 2 is fixed with a baffle 43, one end of which extends to the top of the pallet 4.

[0021] The first support plate 5 is fixed on the end side wall of the second conveyor 3. The first support plate 5 is provided with a first screw 6 that is rotatably connected. One end of the first screw 6 extends toward the end of the support plate 4. A push shaft 7 that is threadedly connected is sleeved on the first screw 6. A pair of first sliding grooves 71 that are symmetrically placed on the side wall of the push shaft 7 are opened.

[0022] A rectangular frame 8 is fixed on one side of the support plate 4. The push shaft 7 can pass through the rectangular frame 8. A pair of support bars 81 placed symmetrically on the upper and lower sides are fixed on the side of the rectangular frame 8 near the first support plate 5. The two support bars 81 are fixed with a card plate 82 on the side close to each other. The card plate 82 can be inserted into the first slide groove 71 and can slide along the first slide groove 71.

[0023] When no object is placed on the tray 4, the lower plate 82 is located in the first slide groove 71 directly below the push shaft 7, and the upper plate 82 is located directly above the first slide groove 71 directly above the push shaft 7. There is a gap between the upper plate 82 and the upper peripheral wall of the push shaft 7, and this gap is greater than the depth to which the lower plate 82 is inserted into the first slide groove 71.

[0024] The packaged logistics box is placed at the head of the first conveyor 2. The logistics box is driven by the first conveyor 2 to approach the baffle 43. After the logistics box contacts the baffle 43, it is pushed to move towards the second conveyor 3. When the logistics box moves onto the pallet 4, the pallet 4 compresses the spring 42 and the telescopic component 41 under the action of the logistics box's gravity. The degree of extension and retraction of the spring 42 and the telescopic component 41 is controlled by the weight of the logistics box. The pallet 4 moves the rectangular frame 8, the support bar 81, and the clamping plate 82 downwards, while rotating the first screw 6.

[0025] If the weight of the logistics box is within the standard range, and the lower card plate 82 is just moved out of the first slide groove 71, while the upper card groove has not moved down to engage with the first slide groove 71 on the upper peripheral wall of the push shaft 7, then the push shaft 7 will only rotate with the first screw 6, and the logistics box with the weight within the standard range can be detected, and the qualified logistics box will be pushed from the pallet 4 to the second conveyor 3 for transport and collection.

[0026] If the weight of the logistics box is less than the standard range, the lower pallet 82 moves down only slightly and does not completely move out of the first groove 71. In this case, the first screw 6 drives the push shaft 7 to perform threaded gear transmission, causing the push shaft 7 to move towards the logistics box end. The push shaft 7 pushes the logistics box off the pallet 4. Similarly, if the weight of the logistics box is greater than the standard range, the upper pallet 82 inserts into the first groove 71, and the push shaft 7 rotates with the first screw 6 to perform threaded gear transmission. Through the above process, the logistics boxes can be detected and sorted according to their weight. Boxes that are underweight or exceed the standard range can be sorted and discharged, improving the automation level of weighing and sorting and increasing work efficiency. At the same time, the depth of the lower pallet 82 inserted into the first groove 71 and the size of the gap between the upper pallet 82 and the upper peripheral wall of the push shaft 7 can be adjusted to control the accuracy of the required standard range for sorting express delivery.

[0027] A pair of support columns 9 are fixed on the base plate 1, and a connecting plate 10 is fixed between the two support columns 9. The connecting plate 10 is located directly above the first conveyor 2 and the second conveyor 3. The connecting plate 10 and the baffle 43 are placed coaxially. A coaxially placed shaft rail 11 is fixedly installed on the connecting plate 10. A coaxially placed second slide groove 111 is opened on the shaft rail 11. A rotatably connected second screw 121 is provided in the second slide groove 111. A threaded slider 13 is provided on the second screw 121. The slider 13 is slidably engaged with the second slide groove 111. A first rotating motor 12 is fixedly installed at one end of the shaft rail 11. The rotating motor 12 and the second screw 121 are placed on the same axis. The output end of the first rotating motor 12 is fixed to one end of the second screw 121. A hanging plate is fixed to the lower end face of the slider 13. A connecting rod 14 is provided on the hanging plate. The connecting rod 14 is placed on the same axis as the first screw 6. A lever 141 is fixedly sleeved on one end of the connecting rod 14. The lever 141 is placed vertically downward. When the first rotating motor 12 is turned on, the output end of the first rotating motor 12 sequentially drives the second screw 121, the slider 13, the hanging plate, the connecting rod 14, and the lever 141. The lever 141 pushes the logistics box to move towards the second conveyor 3.

[0028] The end of the second screw 121 away from the first rotating motor 12 is fixedly fitted with a first transmission wheel 15 placed coaxially. The other end of the first screw 121 is fixed with a first gear 16. A second support plate 173 is fixed on the base plate 1. A rotating rod 17 is rotatably connected to the second support plate 173. The rotating rod 17 is placed coaxially with the second screw 121. A gear disc 171 is fixedly fitted on the end of the rotating rod 17 near the first gear 16. The gear disc 171 meshes with the first gear 16. The end of the rotating rod 17 away from the first gear 16 is fixed with a second transmission wheel 172. A first annular transmission belt 18 is fitted between the first transmission wheel 15 and the second transmission wheel 172. The first rotating motor 12 drives the second screw 121. The second screw 121 drives the slider 13, the hanging plate, the connecting rod 14, and the lever 141 to move. At the same time, the second screw 121 drives the first transmission wheel 15. The first transmission wheel 15 drives the first annular transmission belt 18, the second transmission wheel 172, the rotating rod 17, the gear plate 171, the first gear 16, and the first screw 6 in sequence. Before the logistics box moves onto the pallet 4, the lower clamping plate 82 is inserted into the first sliding groove 71, so that the first screw 6 and the push shaft 7 engage in threaded transmission and move closer to the logistics box, realizing the selective movement of the push shaft 7 and the orderly linkage control of the movement of the logistics box.

[0029] During the resetting process of the deflector plate 141 moving from the second conveyor 3 to the first conveyor 2, the logistics box on the first conveyor 2 may move to the stop bar 43 before the deflector plate 141 is reset. At this time, due to the restriction effect of the logistics box, the deflector plate 141 cannot automatically reset. To solve this problem, the connecting rod 14 and the hanging plate are rotatably connected. A third sliding groove 101, coaxially positioned, is provided on the connecting plate 10. The end of the connecting rod 14 away from the deflector plate 141 passes through the third sliding groove 101 and is connected to the third sliding groove 101. The slot 101 is slidably connected; when a logistics box moves to the stop bar 43 before the turn plate 141 is reset, the connecting rod 14 is rotated to make the turn plate 141 rotate and flip. First, the turn plate 141 is rotated to a horizontal position, and with the action of the first rotating motor 12 and the second screw 121, the turn plate 141 passes through the top of the logistics box from the horizontal position. After the turn plate 141 passes through the logistics box, the connecting rod 14 is rotated again to make the turn plate 141 rotate to a vertical position.

[0030] A second gear 19 is fixedly sleeved at the end of the connecting rod 14 away from the lever plate 141. The second gear 19 is located on the side of the connecting plate 10 away from the shaft rail 11. A first rack 20 is coaxially placed above the third slide groove 101. The first rack 20 is located directly above the support plate 4 and can mesh with the upper end of the second gear 19. A first mounting component is fixed to the upper end of the connecting plate 10, and a first telescopic cylinder 201 is mounted on the first mounting component. The telescopic rod of the first telescopic cylinder 201 is fixed to the upper end face of the first rack 20, and the first rack 20 can move up and down along the side of the connecting plate 10. A coaxially placed... The second rack 21 is located directly above the first conveyor 2. The second rack 21 can mesh with the lower end of the second gear 19. A second mounting component is fixed on the connecting plate 10, and a vertically upward-placed second telescopic cylinder 211 is fixed on the second mounting component. The telescopic rod of the second telescopic cylinder 211 is fixed to the lower end face of the second rack 21. When the first rack 20 or the second rack 21 meshes with the second gear 19, both the first rack 20 and the second rack 21 can rotate the second gear 19 by 90°. First, the first telescopic cylinder 201 and the second telescopic cylinder 211 are activated. The telescopic rod of the first telescopic cylinder 201 retracts, driving the first… As rack 20 moves upward, the telescopic rod of the second telescopic cylinder 211 retracts, causing the second rack 21 to move downward, thus moving both rack 20 and rack 21 away from the second gear 19. At this time, when the turntable 141 moves from the first conveyor 2 to the second conveyor 3, the second gear 19 does not mesh with either rack 20 or rack 21, keeping the turntable 141 vertically downward and pushing the logistics box to move. When the turntable 141 returns to its original position towards the first conveyor 2, the first telescopic cylinder 201 and the second telescopic cylinder 211 are activated first, causing rack 20 and rack 21 to move closer to the second gear 19 until both mesh with it. Then, when the slider 13 moves the hanging plate, connecting rod 14, dial plate 141, and second gear 19, the second gear 19 moves to mesh with the first rack 20. The first rack 20 causes the second gear 19 to rotate 90°. The second gear 19 drives the connecting rod 14, and the connecting rod 14 drives the dial plate 141 to flip to a horizontal position. It continues to move and slide. When it slides above the first conveyor 2, the second gear 19 meshes with the second rack 21 below, thereby driving the dial plate 141 to rotate and flip to a vertically downward position. This achieves the purpose of automatically controlling the multiple rotations of the connecting rod 14 during the reset process of the dial plate 141.

[0031] A strip frame 22 is fixed around the periphery of the third slide groove 101. The inner peripheral wall of the strip frame 22 is in contact with the inner groove wall of the third slide groove 101. The connecting rod 14 passes through the strip frame 22 and can slide along the strip frame 22. A square bushing 23 placed coaxially is fixedly sleeved on the connecting rod 14. The square bushing 23 is located on the side of the connecting plate 10 near the strip frame 22. The side length of the square bushing 23 is equal to the diameter of the connecting rod 14. The upper and lower side walls of the square bushing 23 are in contact with the inner wall of the strip frame 22. The square bushing 23 can slide along the strip frame 22. A notch 2 is opened in the strip frame 22 at the position directly below the first rack 20. 21. A notch 221 is also provided in the strip frame 22 located directly above the second rack 21. When the connecting rod 14 does not need to be rotated, the sliding and flipping of the connecting rod 14 during movement can be reduced by the cooperation between the square bushing 23 and the strip frame 22. When the connecting rod 14 needs to be rotated to flip the lever 141, the first rack 20 or the second rack 21 meshes with the second gear 19, and the square bushing 23 is located in the notch 221 at the corresponding position of the first rack 20 or the second rack 21. At this time, rotation and flipping can be performed to improve the stability of the connecting rod 14 during movement.

[0032] The first conveyor 2 and the second conveyor 3 are both fixedly supported on the base plate 1 by mounting blocks. The first conveyor 2 and the second conveyor 3 each include a pair of parallel drive rollers. An annular conveyor belt 31 is sleeved between the drive rollers. A second rotating motor 32 is fixedly mounted on the mounting block. The output end of the second rotating motor 32 is provided with a rotating shaft. The rotating shaft is placed coaxially with the second screw 121. A third drive wheel 33 is fixedly sleeved on the rotating shaft and placed coaxially. The third drive wheel 33 is connected to the drive roller at the head end of the corresponding conveyor through a second annular drive belt.

[0033] A collection box 24 is provided on the base plate 1. The collection box 24 is located on the side of the pallet 4 away from the push shaft 7. The upper end of the collection box 24 is open. The logistics box pushed down by the push shaft 7 falls into the collection box 24 for collection.
