Description

Technical Field

[0001] The utility model relates to the technical field of pallet depalletizing equipment, in particular to a depalletizing mechanism for a pallet maintenance line. Background Art

[0002] Pallets are the medium that transforms static goods into dynamic goods, a cargo platform, and an active platform, or a movable ground. Even if the goods are placed on the ground and lose their flexibility, they will immediately become active and become flexible mobile goods once they are loaded on the pallet, because the goods loaded on the pallet are ready to be put into motion at any time.

[0003] During the production process, pallets need to be inspected to check whether the nails on the other side of the pallet are in place. Therefore, the stacked pallets need to be depalletized and turned over so that the side of the pallet that needs inspection faces up. When depalletizing, the horizontally placed pallet on the conveyor line is first turned 90 degrees, and then the pushing mechanism pushes the pallet to the distribution mechanism. The distribution of the distribution mechanism flips the pallet again 90 degrees, so that the inspection side of the pallet is in an upward position. However, when depalletizing and turning, the pushing mechanism needs to wait for the distribution mechanism to complete the distribution of the pallets one by one before it can come back to push the next batch of pallets. This results in a long back and forth travel of the pushing mechanism, which is more time-consuming, thereby reducing the depalletizing efficiency of the pallets.

[0004] Therefore, there is an urgent need for a destacking mechanism for a pallet maintenance line to improve the efficiency of destacking the pallets. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a destacking mechanism for a pallet maintenance line, which is used to solve the problem of low destacking efficiency of the existing pallet destacking mechanism.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] See attached Figure 1-3 , shown is a depalletizing mechanism for a pallet repair line, comprising a distribution unit 1, a transfer unit 2, a push unit 3 and a receiving unit 4 arranged in sequence, wherein the distribution unit 1 comprises a first frame 5, on which a first transfer plate 6 is arranged, in order to reduce the friction force when the pallet 33 slides on the first transfer plate 6, a plurality of ribs are arranged in parallel on the first transfer plate 6, and the contact area between the pallet 33 and the first transfer plate 6 is reduced by the ribs, thereby making the pallet 33 slide more smoothly, and a connecting beam 7 is respectively arranged on both sides of the first frame 5, and the distribution unit 1 is connected to the transfer unit 2 through the connecting beam 7;

[0034] The transfer unit 2 includes two first linear slide rails 8 fixed on the connecting beam 7, and a first door frame 9 is slidably provided on the two first linear slide rails 8. A pulley is provided at one end of the first door frame 9 corresponding to the first linear slide rail 8, and the pulley slides in cooperation with the first linear slide rail 8. A clamping arm 10 is rotatably provided on both sides of the first door, and a first driving cylinder 11 is hinged between each clamping arm 10 and the first door frame 9. The two clamping arms 10 make circular arc motions towards each other under the action of the first driving cylinder 11, and the tray 33 from the pushing unit 3 can be clamped and fixed by the clamping arms 10. At the same time, the transfer unit 2 also includes a first driving motor 12 arranged at the bottom of one end of the first frame 5, and the output end of the first driving motor 12 is provided with a first driving shaft 13 through a chain. The first driving shaft 13 is rotatably arranged at the end of the first frame 5, and first driving gears 14 are provided at both ends of the first driving shaft 13. The wheel 14 is provided with a first driving belt 15, the other end of the first driving belt 15 is connected to one end of the connecting beam 7 through a follower gear, and the first driving belt 15 is connected to the first door frame 9 through a tensioner. It can be seen that the first driving motor 12 uses the first driving belt 15 to drive the first door frame 9 equipped with the clamping arm 10 to slide along the first linear slide rail 8, and then the pallet 33 from the pushing unit 3 is pushed to the distribution unit 1 for distribution. By adding a transfer unit 2 between the distribution unit 1 and the pushing unit 3, the pushing unit 3 no longer needs to push the pallet 33 to the distribution unit 1 over a long distance to wait for distribution one by one, thereby shortening the travel and pushing time of the pushing unit 3. The pushing unit 3 is only responsible for the first 90-degree flip of the pallet 33 from the receiving unit 4 and pushing the flipped pallet 33 into the first door frame 9, thereby improving the efficiency of destacking the pallet 33;

[0035] See also Appendix Fig. 9 As shown, the distribution unit 1 also includes a second door frame 16 arranged at one end, and a distribution arm 18 is rotatably provided on the top of the second door frame 16. At the same time, a second driving cylinder 17 for controlling the arc swing of the distribution arm 18 is provided on the top of the second door frame 16. When in use, the tray 33 is pushed to the second door frame 16 by the clamping arm 10 and the first driving motor 12, and the second driving cylinder 17 controls the opening and closing of the distribution arm 18 to turn the trays 33 90 degrees one by one, and put the maintenance side in an upward position;

[0036] Also, see Attachment Figure 5-7The pushing unit 3 shown includes a second frame 20, one end of which is provided with a hinge seat 28, and the second frame 20 is hinged with a second transfer plate 21 through the hinge seat 28, and the middle part of the second transfer plate 21 is symmetrically provided with two second linear slides 22 along the length direction, and a flap 23 is slidably provided on the two second linear slides 22, and at the same time, a second driving motor 24 is installed at the bottom of one end of the second transfer plate 21 close to the first transfer plate 6, and the output end of the second driving motor 24 is provided with two second driving belts 25 through a second driving gear 26, and the second driving belt 25 is connected to the flap 23. When in use, the second driving motor 24 uses the second driving belt 25 to drive the flap 23 to move along the second linear slide 22 to push the tray 33 into the first door frame 9;

[0037] In addition, the second frame 20 is located below the second transfer plate 21 and is hinged with two third drive cylinders 27. The output end of the third drive cylinder 27 is hinged to one end of the second transfer plate 21. When in use, the third drive cylinder 27 acts on the second transfer plate 21 and the flap 23 to rotate 90 degrees along the hinge seat 28 as a whole, so that the tray 33 placed horizontally on the receiving unit 4 is turned 90 degrees for the first time.

[0038] Also, see Attachment Figure 8 , the receiving unit 4 includes a third frame 29, a third drive motor 30 is installed on the third frame 29, the output end of the third drive motor 30 is provided with a third drive belt 31 through a third drive gear 32, and the third drive belt 31 is installed on the third frame 29. When in use, the whole stack of pallets 33 is conveyed to the receiving unit 4 through the conveyor line, and then the pallet 33 is moved to the top of the flap 23 by the third drive belt 31 for the first flip from horizontal to vertical;

[0039] Also, see Attachment Figure 4 , the height of the first frame 5 decreases from one end of the second door frame 16 to one end of the second frame 20. This design ensures that when the tray 33 in the vertical rotation state is pushed, the tray 33 is always in a backward state, thereby preventing the tray 33 from tipping forward;

[0040] Also, see Attachment Figure 2 The length of the two connecting beams 7 is greater than the length of the first transfer plate 6. At the same time, a connecting port 19 is formed at one end close to the first door frame 9. When the second transfer plate 21 is flipped, it can fall into the connecting port 19, which can ensure the continuity of pushing the pallet 33.

[0041] When using, see the attached Fig.10As shown, first, the third driving cylinder 27 acts on the second transfer plate 21 and the flap 23 to rotate 90 degrees clockwise along the hinge seat 28 as a whole. At this time, the flap 23 is horizontally placed between the two third driving belts 31 and is lower than the position of the third driving belt 31. In this way, the tray 33 can reach the top of the flap 23 under the action of the third driving belt 31. Then, the third driving cylinder 27 drives the second transfer plate 21 and the flap 23 to rotate 90 degrees counterclockwise. At this time, the tray 33 changes from the original horizontal state to the vertical state under the action of the flap 23. Then, the second driving motor 24 uses the second driving belt 25 to drive the flap 23 to push the tray 33 into the first door frame 9. Then, the first driving cylinder 11 drives the two clamping arms 10 realizes clamping of the pallet 33, and then the first drive motor 12 uses the first drive belt 15 to drive the first door frame 9 holding the pallet 33 to slide along the first linear slide rail 8 to the second door frame 16. When the pallet 33 is flipped for the second time, the second drive cylinder 17 controls the distribution arm 18 to open, and then the first drive motor 12 controls the first door frame 9 to push the pallet 33 forward, and the pushing distance is equal to the height of one pallet 33. At this time, the pallet 33 is flipped 90 degrees from the first transfer plate 6 under the action of the thrust and falls off. When the first pallet 33 is flipped, the distribution arm 18 is closed, and then the first drive motor 12 drives the first door frame 9 and cooperates with the distribution arm 18 to open and push the pallets 33 one by one to realize flipping and distribution.

[0042] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
