DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] Example: See Figure 1 - Figure 4 In the present embodiment, a pallet destacking device for a pallet destacking machine is provided, which is specifically used for XXXX and specifically comprises: a lifting platform 11, a conveyor 12 and a destacking mechanism 13, wherein the destacking mechanism 13 comprises two groups of destacking units 14 arranged symmetrically, wherein the destacking unit 14 comprises a plurality of groups of destacking components 15 arranged up and down, wherein the destacking components 15 comprise an insert block 16 and an articulated seat 17, wherein the insert block 16 is articulated on the articulated seat 17, wherein the articulated seat 17 is provided with a first driving component 18, wherein the first driving component 18 is a motor, and the first driving component 18 drives the insert block 16 to swing and insert the insert block 16 under the groove 19 of the pallet, wherein the destacking components 15 of different heights all support the stack formed by the pallets, and a gap is left between the top of the lower stack and the bottom of the upper stack.

[0024] Specifically, in this embodiment, the lifting platform 11 is a hydraulic lifter, which is driven by hydraulic pressure to lift the pallet, and the conveyor 12 is a chain conveyor 12, which is driven by a motor to convey the pallet. Specifically, the destacking unit 14 of this embodiment is provided with four layers of destacking groups, which are respectively a first layer destacking group 21, a second layer destacking group 22, a third layer destacking group 23 and a fourth layer destacking group 24 from bottom to top, wherein each layer is provided with four groups of destacking components 15. Before unstacking, the pallets need to be layered, the lifting platform 11 is in a low position, and the pallets are stacked and placed on the lifting platform 11. The lifting platform 11 drives the pallets to rise. When the pallets are lifted to a high position, the fourth-layer unstacking group 24 is started, and the first driving component 18 drives the insert block 16 to be inserted into the groove 19 of the pallet. At this time, the pallets supported by the fourth-layer unstacking group 24 form a first stack 25, and the lifting platform 11 drives the remaining pallets to move downward, so that the uppermost pallet in motion is disengaged from the bottom of the first stack 25. Similarly, the third-layer unstacking group 23 separates some pallets to form a second stack 26. Similarly, the pallets supported by the second-layer unstacking group 22 form a third stack 27. The pallets supported by the first-layer unstacking group 21 form a third stack 28. The pallets form a fourth stack 28. At this time, all the pallets are divided into a first stack 25, a second stack 26, a third stack 27 and a fourth stack 28 from bottom to top. Each group of stacks is supported by a layer of stacking group. Compared with the traditional method of using a single stacking component 15 and an insert block 16 to support the weight of all pallets, the utility model divides the pallets into multiple groups of stacks, which are supported by different layers of stacking components 15. The insert block 16 is against the bottom of the groove 19. The groove 19 is the load-bearing part of the pallet and has a relatively weak structure. The design of multiple layers of insert blocks 16 sharing the weight of the pallet in this embodiment can reduce the pressure between a single insert block 16 and the pallet, thereby effectively reducing the possibility of damage to the pallet and increasing the service life of the pallet.

[0025] After the layering is completed, the pallets need to be destackered. The destacking process starts from the bottom pallet of the first stack 25. Specifically, the first stack 25 is supported by the lifting platform 11. At this time, the insert block 16 of the first-layer destacking group 21 retreats, and the lifting platform 11 drives the first stack 25 to drop by one pallet thickness. At this time, the insert block 16 of the first-layer destacking group 21 is inserted into the groove 19 of the second pallet from bottom to top again, and the lifting platform 11 continues to drive a pallet to descend and place it on the conveyor 12, and the conveyor 12 then outputs the pallet. In the same way, the remaining first stack 25, second stack 26, third stack 27 and all pallets in the third stack 27 can be destackered and output.

[0026] In this embodiment, the stacking component 15 further includes a second driving component 29 for driving the articulated seat 17 to rise and fall. The second driving component 29 adopts a linear driving module such as a hydraulic cylinder and a screw motor. The second driving component 29 is used to adjust the vertical distance between adjacent stacking groups. In actual work, pallets of different thicknesses are designed for production needs, and the stacking heights of pallets of different thicknesses after stacking are also inconsistent. The design of the second driving component 29 allows the spacing of each stacking group to be adjusted according to the stacking height to adapt to the stacking of pallets of different thicknesses, which has universal applicability.

[0027] See also Figure 4 and Figure 5 The left and right sides of the unpacking mechanism 13 are provided with guard plates 3, the guard plates 3 are provided with notches 31 for the insert block 16 to swing, a first flexible pad 34 is provided above the notch 31, a retaining ring 32 is connected and fixed to the notch 31, a second flexible pad 35 is provided on the retaining ring 32, a baffle 33 is connected and fixed to the insert block 16, and a third flexible pad 36 and a fourth flexible pad 37 are provided on both sides of the baffle 33 respectively, which are adapted to the first flexible pad 34 and the second flexible pad 35. When the unpacking component 15 is in operation, its insert block 16 swings around the hinge seat 17, and the insert block 16 needs to provide a corresponding force to realize the process from swinging to stopping the swinging, and the force is generated when the baffle 33 contacts the retaining ring 32, and the baffle 33 contacts the guard plate 3 of the unpacking mechanism 13. Specifically, when the insert block 16 is extended (the insert block 16 is inserted into the groove 19 of the tray), the baffle 33 contacts the guard plate 3, and the first flexible pad 34 collides with the third flexible pad 36 to form a buffer, so that the insert block 16 stops extending; when the insert block 16 retracts (the insert block 16 is extended from the groove 19 of the tray), the baffle 33 contacts the retaining ring 32, and the second flexible pad 35 collides with the fourth flexible pad 37, so that the insert block 16 stops retracting. Through the arrangement of the first flexible pad 34, the second flexible pad 35, the third flexible pad 36 and the fourth flexible pad 37, the insert block 16 of the stacking component 15 forms an effective buffer in the process of swinging to stop. On the one hand, it can avoid the impact caused by hard contact affecting the service life of the stacking mechanism 13, and on the other hand, it can reduce the noise during the collision. The flexible pad in this embodiment can be made of rubber and other materials.

[0028] The plug block 16 adopts a hollow structure and has a rounded corner structure at its end, which includes two sets of side plates 41 and a set of arc plates 42. The convex arc surface 43 of the arc plate 42 constitutes the rounded corner structure part of the end of the plug block 16. The design of the hollow structure can reduce the mass of the plug block 16, thereby reducing the load of the first driving component 18, making the plug block 16 more flexible and light when driven. The design of the rounded corner structure can reduce the scratches caused by the friction of the plug block 16 on the groove 19 when it is inserted.

[0029] The rear side of the unstacking mechanism 13 is provided with a main limit plate 51, and the front side is symmetrically provided with two groups of auxiliary limit plates 52. The upper end of the auxiliary limit plate 52 is provided with a bending portion 53. The main limit plate 51 is located on the rear side of the unstacking mechanism 13, and is used to prevent the pallet from falling. The auxiliary limit plate 52 is located on the front side of the unstacking mechanism 13, and takes effect during the stacking process. The upper end thereof is provided with a bending portion 53. When the pallet is stacked, one end thereof slides along the bending portion 53, and the other end is blocked by the main limit plate 51, so that the pallets stacked at the bottom are better aligned, effectively avoiding the pallet from falling when it is stacked too high.

[0030] See also Figure 6 The destacking mechanism 13 includes four groups of legs 61, and a bottom plate 63 is welded and fixed to the bottom of the legs 61 through triangular ribs 62, and a through hole 64 is provided in the bottom plate 63. The through hole 64 can be fixedly connected to the ground through bolt fasteners, so as to realize the installation of the destacking mechanism 13. The legs 61 are square in cross section, and a rib 62 is welded around them. The arrangement of the rib 62 can enhance the stability of the destacking mechanism 13.

[0031] A height-limiting cross bar 7 is provided on the top of the unstacking mechanism 13. By providing the height-limiting cross bar 7, the stacking height of the pallets is limited, which can effectively avoid the occurrence of falling accidents caused by the pallets being stacked too high, and is regarded as a reasonable design for safe operation.

[0032] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
