Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-4 , an automatic goods stacking device, including a main conveyor belt 1 and a side conveyor belt 27. The transmission direction of the side conveyor belt 27 is opposite to that of the main conveyor belt 1, and the side conveyor belt 27 is located below the main conveyor belt 1 in the vertical direction. A load-carrying plate 2 is provided at the end of the main conveyor belt 1. Supporting plates 3 are symmetrically provided on both sides of the load-carrying plate 2. Sliding holes 4 are formed on the side surfaces of the supporting plates 3. Clamping blocks 5 are slidably connected inside the sliding holes 4. A first lifting cylinder 6 is installed through the top end of the supporting plate 3. One end of the output shaft of the first lifting cylinder 6 is fixedly connected with a movable plate 7. A first clamping cylinder 8 is installed on the side surface of the movable plate 7. The telescopic end of the first clamping cylinder 8 movably penetrates through the movable plate 7 and is fixedly connected with the side surface of the clamping block 5. Guide rods 9 are fixedly connected to both sides of the top end of the supporting plate 3. Both ends of the movable plate 7 are respectively slidably sleeved outside the two guide rods 9. The surface of the load-carrying plate 2 is flush with the surface of the main conveyor belt 1;

[0024] In the technical solution adopted above, the items on the main conveyor belt 1 are intermittently conveyed onto the loading plate 2. When the first item is conveyed onto the loading plate 2, at this time, the clamping blocks 5 are located at the bottommost end of the sliding holes 4. The first clamping cylinders 8 on both sides are started to drive the clamping blocks 5 on both sides to move closer to the item until the item is clamped and fixed. Then, the first lifting cylinder 6 is started to drive the movable plate 7 and the clamping blocks 5 to move upward, lifting the item to a certain height. After lifting, the next item can be conveyed onto the loading plate 2 through the main conveyor belt 1. This item is located below the lifted item at this time, and there is a gap in height between the two. Then, the first clamping cylinder 8 is retracted to make the clamping blocks 5 return to the inside of the sliding holes 4 again. At this time, the item above is not under the clamping force and will fall onto the top of the item below, and the two are stacked together. Finally, the first lifting cylinder 6 is reset to drive the clamping blocks 5 to move down to the bottommost end, and the item below is clamped and lifted again. This process is repeated to stack and palletize the items.

[0025] The main conveyor belt 1 is installed at the inner bottom end of the fixed frame 10. The bottom end of the support plate 3 is fixedly connected with support legs 11, and the side surface of the support legs 11 is fixedly connected with the fixed frame 10 through connecting rods 12.

[0026] In the technical solution adopted above, the position of the support plate 3 is fixed through the action of the support legs 11 and the connecting rods 12. The two support plates 3 are in an L-shaped structure below, and the two sides at the bottom end of the loading plate 2 are just placed inside the two support plates 3.

[0027] Guide plates 13 are symmetrically installed on both sides at the top end of the fixed frame 10, and the width of the end of the guide plate 13 is the same as the width of the loading plate 2.

[0028] In the technical solution adopted above, as shown in the attached drawing, the front end of the guide plate 13 is inclined, so as to conveniently guide the items on the main conveyor belt 1 onto the loading plate 2 exactly and prevent the items from running off.

[0029] A first guide rail 14 is provided at the bottom end of the loading plate 2. A first guide groove is opened at the top end of the first guide rail 14, and a first lead screw 15 is rotatably installed inside the first guide groove. One end of the first guide rail 14 is provided with a first motor 16, and one end of the output shaft of the first motor 16 is fixedly connected with the end of the first lead screw 15. A first movable seat 17 is fixedly connected to the middle of the bottom end of the loading plate 2. The first movable seat 17 is slidably connected in the first guide groove, and the first movable seat 17 is threadedly sleeved outside the first lead screw 15.

[0030] In the technical solution adopted above, by driving the first lead screw 15 to rotate forward or backward through the first motor 16, the loading plate 2 will be driven to slide horizontally along the direction of the first guide rail 14 through the action of the first movable seat 17. Thus, when the items on the loading plate 2 are palletized to a certain height, the loading plate 2 slides outwards, facilitating the transfer of the items on the loading plate 2 in the following process.

[0031] There is a second guide rail 18 vertically arranged behind the first guide rail 14. A second guide groove is provided at the top of the second guide rail 18, and a second movable seat 21 is slidably connected through the second guide groove. A second lifting cylinder 22 is installed at the top of the second movable seat 21. The top of the telescopic end of the second lifting cylinder 22 is fixedly connected with a fixing plate 23. Fixed arms 24 are symmetrically installed at both ends of the side surface of the fixing plate 23. A second clamping cylinder 25 is installed at one end of the side surface of the fixed arm 24, and the telescopic end of the second clamping cylinder 25 movably penetrates through the fixed arm 24 and is fixedly connected with a clamping plate 26;

[0032] In the above technical solution, when the load plate 2 slides outwards to the corresponding position, the second clamping cylinders 25 on both fixed arms 24 are started, so that the clamping plates 26 on both sides are driven to move closer to each other until all the items on the load plate 2 are clamped and fixed, which is convenient for the transfer of the items. The bottom end of the clamping plate 26 is flush with the placement surface of the load plate 2 or slightly higher than the surface of the load plate 2.

[0033] A second motor 20 is installed at the end of the second guide rail 18. A second lead screw 19 is rotatably installed inside the second guide groove, and one end of the second lead screw 19 is connected to the output shaft of the second motor 20. The second movable seat 21 is threadedly sleeved outside the second lead screw 19;

[0034] In the above technical solution, the second motor 20 drives the second lead screw 19 to rotate, thereby driving the second movable seat 21 to translate along the direction of the second guide rail 18. Thus, the items clamped by the clamping plates 26 also translate until the items translate above the side conveyor belt 27. Then, the second lifting cylinder 22 is started to drive the items to move down until they are placed on the side conveyor belt 27, and the items are released by the second clamping cylinder 25. Thus, the stacked items will be conveyed out by the side conveyor belt 27 for the next process or packing into boxes. As shown in the attached drawing, the load plate 2 has an L-shaped structure to prevent the items conveyed by the main conveyor belt 1 from running out due to inertia, and the structural design height of the load plate 2 does not affect the translation of the fixed arm 24.

[0035] Two positioning rods 29 are fixedly connected to the upper and lower positions of the outer side surface of the clamping plate 26. Positioning blocks 28 are fixedly connected to the upper and lower surfaces of the end of the fixed arm 24, and the two positioning rods 29 respectively movably penetrate through the two positioning blocks 28;

[0036] In the above technical solution, through the action of the positioning rods 29 and the positioning blocks 28, not only can the movement of the clamping plate 26 be guided, but also the gravity of the clamping plate 26 can be borne, preventing the accident that the telescopic end of the second clamping cylinder 25 is stressed alone and breaks.

[0037] Working principle:

[0038] The articles are gradually fed onto the loading plate 2 via the main conveyor belt 1. When a single article is fed onto the loading plate 2, the article is clamped and fixed by the clamping block 5, and the article is lifted to a certain height by the first lifting cylinder 6, so as not to affect the feeding of the next article onto the loading plate 2. When the next article reaches the loading plate 2, the clamping block 5 is released, so that the upper article is stacked on the lower article. Then, the lower article is clamped and lifted again by the clamping block 5 and the first lifting cylinder 6, and so on, to achieve the palletizing effect of the articles. When the articles are palletized to a certain extent, the loading plate 2 is driven by the first guide rail 14 to slide outwards to a corresponding distance, and the articles on the loading plate 2 are clamped and fixed by the clamping plate 26. Then, the clamped articles are driven by the second guide rail 18 to translate perpendicular to the direction of the main conveyor belt 1 until they are translated above the side conveyor belt 27. At this time, the loading plate 2 returns to the initial position to palletize new articles again. The stacked articles translated above the side conveyor belt 27 are placed on the side conveyor belt 27 by the second lifting cylinder 22, and the clamping plate 26 is released, so that the palletized articles are conveyed to the next process.

[0039] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
