DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] In the description of the utility model, please note that terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like are based on the positional relationship shown in the drawings, and are intended to simplify the description and facilitate understanding, and not to limit the actual orientation or construction mode of the device or element, therefore should not be regarded as a constraint on the utility model.

[0026] Please refer to Figure 1 A finished product warehouse stacking machine, its structure is consistent with prior art device, mainly contains a bearing tray 5 for placing box type finished product material.

[0027] It is particularly noteworthy that in practical application, one side of the bearing tray 5 is provided with a mechanical hand (usually located at the rear side or front side, not specifically shown in the present application), which can stack the scattered and stacked box type finished product materials on the upper side of the bearing tray 5.

[0028] In view of this, in order to ensure that the bearing tray 5 can smoothly carry out subsequent operation after placing a sufficient number of box type finished product materials, the device is provided with a material moving mechanism 4 at the lower side of the bearing tray 5. The material moving mechanism 4 includes a ring-shaped transmission belt and a transmission member matched with the inner side of the transmission belt. When the bearing tray 5 is placed above the ring-shaped transmission belt, the ring-shaped transmission belt is responsible for transferring the bearing material. Usually, after the box type finished product material is transferred by the ring-shaped transmission belt, a forklift is ready at the tail end in order to further transport.

[0029] In addition, it needs to be clear that in actual operation, since the bearing tray 5 has a number of box type finished product materials stacked and placed thereon, the bearing tray 5 needs to be fixed at a position first, and then placed on the ring-shaped transmission belt for driving by the transmission belt. Therefore, the device is provided with a jacking mechanism 3 at the front and rear ends of the lower side of the bearing tray 5, which can push the bearing tray 5 upward, so that the lower end face height of the bearing tray 5 is greater than the upper end face height of the ring-shaped transmission belt. At this time, the ring-shaped transmission belt and the bearing tray 5 are in a separated state. After the box type finished product material is stacked on the bearing tray 5, the jacking mechanism 3 moves the bearing tray 5 downward so that it contacts the ring-shaped transmission belt, and then the ring-shaped transmission belt starts to bear and transfer the material.

[0030] Please refer to Figure 1 , Figure 2 Different from the prior art, a shaping mechanism is arranged on one side of the bearing tray 5. The shaping mechanism can push multiple box type finished product materials stacked on the upper end of the bearing tray 5 (in actual application, the tray is usually provided with multiple layers, and each layer contains several box bodies) to stack with each other, so as to avoid damage caused by separation of the box bodies near the edge of the tray.

[0031] As Figure 2 , Figure 3As shown, specifically, the shaping mechanism is composed of four head-to-tail driven plates 6, and the projections of the four driven plates 6 on the vertical plane jointly form a rectangular structure.

[0032] In addition, a rectangular frame 7 is arranged between the four driven plates 6, and four clamping plates 8 are arranged on the inner side of the frame.

[0033] Therefore, by fixing a slide rod 13 on each clamping plate 8 on the side close to the corresponding driven plate 6, and constraining the slide rods 13 to be in sliding connection with the rectangular frame 7, and by connecting each slide rod 13 on the side close to the corresponding driven plate 6 to the driven plate 6 in a movable manner, the distance between the clamping plate 8 and the side end of the rectangular frame 7 can be changed simultaneously by changing the distance between the driven plate 6 and the side end of the rectangular frame 7 in practice, and at this time, the clamping plate 8 can push the box-shaped finished materials by the shrinkage effect to reduce the gap between the single-layer materials.

[0034] It should be emphasized that in practice, the robot continuously places the scattered box-shaped finished materials on the bearing tray 5, and according to a preset program, once the number of single-layer box-shaped finished materials on the bearing tray 5 reaches the standard, the robot adjusts the falling height to stack the materials of the previous layer. After the robot changes the falling height, the device can control the rectangular frame 7 and the driven plate 6 to change their own height so that they are at the same height as the box-shaped finished materials that have just been stacked in a single layer, and at this time, by changing the distance between the clamping plate 8 and the side end of the rectangular frame 7, the clamping plate 8 can be used to force the gap between the expected layer of box-shaped finished materials to be reduced.

[0035] Therefore, the device is further provided with an up-down displacement member 1 on one side of the rectangular frame 7, and the up-down displacement member 1 is in movable connection with the driven plate 6, and by using the up-down displacement member 1, the height of the rectangular frame 7 and the driven plate 6 can be flexibly adjusted.

[0036] As shown in Figure 2 , Figure 3 The up-down displacement member 1 includes a follower plate, limit shafts are arranged on the front and rear sides of the follower plate, a lead screw is screwed in the middle segment of the follower plate, and a driving motor is key-connected to the upper end of the lead screw. Therefore, by limiting the limit shafts and the lead screw by using the shell of the up-down displacement member 1, the technical effect of controlling the height of the follower plate by the driving motor can be achieved.

[0037] In practice, the follower plate is fixedly connected with the rectangular frame 7, and the rectangular frame 7 is movably connected with the driven plate 6, so that the height of the rectangular frame 7 and the driven plate 6 can be changed by the up-down displacement member 1.

[0038] In addition, the device ensures that the vertical center line of the rectangular structure composed of the four driven plates 6 is completely coincident with the center line of the bearing tray 5 and the rectangular frame 7, so as to effectively avoid any stroke conflict between the rectangular frame 7 and the clamping plate 8 and the box-shaped finished material when the rectangular frame 7 moves up and down.

[0039] In practice, the robot will place the box-shaped finished material above the bearing tray 5 as much as possible during the box-shaped finished material stacking process, and ensure that the distance between the single-layer multiple box-shaped finished materials is appropriate. By constraining the vertical center line of the rectangular structure composed of the four driven plates 6 to be coincident with the vertical center line of the bearing tray 5 and the rectangular frame 7, it can be ensured that the horizontal distance between the multiple clamping plates 8 and the corresponding side box-shaped finished materials is almost the same, which can avoid the stroke conflict caused by the too small distance between the single clamping plate 8 and the corresponding box-shaped finished material.

[0040] Please refer to Figure 3 and Figure 4 , one side of the four driven plates 6 is configured with a driving member. Through the driving member, the distance between the four driven plates 6 and the side end of the rectangular frame 7 in the horizontal direction can be adjusted, so as to realize the adjustment of the distance between the clamping plate 8 and the side end of the rectangular frame 7.

[0041] Further, the device is rotatably connected with a synchronous part 9 at the four corners of the rectangular frame 7 through a positioning shaft 10, and each synchronous part 9 is rotatably connected with two adjacent driven plates 6 through a pivot 11. By using the synchronous part 9, the height between the rectangular frame 7 and the driven plate 6 can be relatively fixed, so as to ensure that the up-down displacement member 1 can drive the driven plate 6 to realize height transfer through the rectangular frame 7.

[0042] At the same time, the design of the device ensures that the two positioning shafts 10 and the two pivots 11 corresponding to each driven plate 6 form a parallelogram structure. By virtue of the characteristics of the parallelogram, as shown in Figure 7 , only the position of a single driven plate 6 needs to be adjusted, and the synchronous adjustment of the positions of multiple driven plates 6 can be realized.

[0043] Therefore, the device ensures that the four driven plates 6 and the side end of the rectangular frame 7 are equidistant in the horizontal direction. This design enables the four driven plates 6 to move synchronously, thereby avoiding the problem of too short distance between a single driven plate 6 and the rectangular frame 7, and further ensuring that the clamping plate 8 has sufficient range of motion.

[0044] Please refer to Figure 3 , Figure 4 and Figure 5 , the driving member is mainly composed of a cylinder 2, and the fixed end of the cylinder 2 is rotatably connected with the up-down displacement member 1.

[0045] Meanwhile, the movable end of the cylinder 2 is rotationally connected with a matching piece 12, and the matching piece 12 is fixedly connected with one of the driven plates 6.

[0046] Please refer to Figure 3 and Figure 6 Specifically, each slide rod 13 is fixedly connected with a contact block 15 at one end close to the corresponding driven plate 6, and the contact block 15 is in close contact with the driven plate 6 at one end close to the driven plate 6. Figure 7 As shown in Figure 3 , the movement direction of the driven rod in the device is positively correlated with the movement direction of the clamping plate 8, so that, by virtue of the close contact effect between the contact block 15 and the driven plate 6, when the distance between the driven rod and the rectangular frame 7 is reduced, the distance between the clamping plate 8 and the side end of the rectangular frame 7 is increased.

[0047] In addition, the end of the contact block 15 close to the driven plate 6 is designed to be spherical, aiming to reduce the contact area with the driven plate 6, and thus reduce the frictional resistance.

[0048] Meanwhile, since the diameter of the contact block 15 is greater than that of the slide rod 13, the device is provided with a compression spring 14 between the contact block 15 and the outside of the rectangular frame 7, and the two ends of the spring are in close contact with the contact block 15 and the rectangular frame 7 respectively, so as to make the clamping plate 8 have a tendency to move to the side of the rectangular frame 7, thereby achieving the reset function.

[0049] In the actual application process of the utility model:

[0050] Firstly, the upper end height of the jacking mechanism 3 is used to position the bearing tray 5 above the jacking mechanism 3, so as to ensure that the bearing tray 5 is completely aligned with the vertical center line of the rectangular frame 7 (this step can be completed by a mechanical arm), at this time, the bearing tray 5 and the material moving mechanism 4 are in a non-contact state;

[0051] Then, the mechanical arm grasps and transfers the scattered box-shaped finished product materials to the upper end of the bearing tray 5 according to the predetermined program;

[0052] Subsequently, after the mechanical arm completes the placement of the expected number of single-layer box-shaped finished product materials on the upper end of the bearing tray 5, the mechanical arm places the newly grasped box-shaped finished product materials above the lower layer of box-shaped finished product materials according to the program, and at the same time, the upper and lower displacement member 1 drives the rectangular frame 7 to move to the height of the single-layer placed box-shaped finished product materials;

[0053] Subsequently, the cylinder 2 starts to contract, and the distance between the multiple driven plates 6 and the rectangular frame 7 is synchronously reduced, and at the same time, the distance between the clamping plate 8 and the rectangular frame 7 is synchronously increased, and they work together to push the box-shaped finished product materials to be closely attached, effectively reducing the gap between adjacent materials.

[0054] Finally, through continuously performing the above steps, the clamping plate 8 clamps and pushes the box-shaped finished materials layer by layer. When the box-shaped finished materials on the upper side of the single carrying tray 5 reach the expected number, the jacking mechanism 3 drives the carrying tray 5 to descend and make it contact with the material moving mechanism 4, and under the action of the material moving mechanism 4, the carrying tray 5 continues to be transferred.

[0055] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
