[0027] Example 1

[0028] In conjunction Figures 1 to 4 As shown, a stacking apparatus of the present application is schematically shown, including a frame 10, a lifting mechanism 20, and a transverse movement mechanism 30.

[0029] The lifting mechanism 20 comprises a lifting slider 21 connected to the frame 10 and a lifting guide rail 22 vertically arranged and slidably connected to the lifting slider 21, which enables the lifting guide rail 22 to ascend or descend relative to the frame 10. The bottom end of the lifting guide rail 22 is provided with a lifting fork 23 capable of forking up materials. The lifting mechanism 20 further comprises a lifting piston cylinder 24 connected to the frame 10, and the piston of the lifting piston cylinder 24 is connected to the lifting fork 23. When the lifting piston cylinder 24 extends, the lifting fork 23 descends relative to the frame 10 through the lifting guide rail 22 and the lifting slider 21, and when the lifting piston cylinder 24 retracts, the lifting fork 23 ascends relative to the frame 10 through the lifting guide rail 22 and the lifting slider 21.

[0030] The transverse movement mechanism 30 comprises a transverse movement guide rail 31 horizontally fixedly connected to the frame 10 and a plurality of transverse movement sliding tables 32 slidably connected to the transverse movement guide rail 31, which enables the plurality of transverse movement sliding tables 32 to transversely move relative to the frame 10. The transverse movement sliding table 32 is provided with a horizontal conveying device 321, which is preferably a chain and plate line conveyor, to horizontally convey materials. The production equipment at the front end of the stacking device can convey materials to the horizontal conveying device 321, and the horizontal conveying device 321 has horizontal conveying power to drive the materials.

[0031] The movement trajectory of the lifting fork 23 intersects with the movement trajectory of the transverse movement sliding table 32, which enables the lifting fork 23 to lift the materials on the transverse movement sliding table 32.

[0032] The transverse movement sliding table 32 has a lifting position state and a standby position state. When the transverse movement sliding table 32 is in the lifting position state, the transverse movement sliding table 32 is located at the lifting mechanism 20, and at this time, the production equipment at the front end of the stacking device can directly convey materials to the horizontal conveying device 321 of the transverse movement sliding table 32 in the lifting position state through the conveying line, and the lifting fork 23 of the lifting mechanism 20 can be lowered to fork up the materials on the horizontal conveying device 321. When the transverse movement sliding table 32 is in the standby position state, the transverse movement sliding table 32 slides relative to the transverse movement guide rail 31 and moves away from the lifting mechanism 20, and at this time, the horizontal conveying device 321 of the transverse movement sliding table 32 is out of position with the conveying line at the front end of the stacking device. Among the plurality of transverse movement sliding tables 32 on the transverse movement guide rail 31, only one transverse movement sliding table 32 can be in the lifting position state.

[0033] The stacking device has multiple stacking paces, and the working principle of one stacking pace is as follows: one of the horizontal sliding tables 32 is switched to a lifting position, the conveying line at the front end of the stacking device conveys a first material to the horizontal conveying device 321 of the horizontal sliding table 32, and the lifting fork 23 lifts the first material and suspends it above the horizontal conveying device 321. The conveying line at the front end of the stacking device conveys a second material to the horizontal conveying device 321 of the horizontal sliding table 32, and the lifting fork 23 lowers the first material above the second material to realize rapid stacking of the two materials.

[0034] The working principle of another stacking pace is as follows: taking two horizontal sliding tables 32 and two materials as an example, the two horizontal sliding tables 32 are respectively named as a first horizontal sliding table 32 and a second horizontal sliding table 32, and the two materials are respectively named as a first material and a second material. The first horizontal sliding table 32 is switched to a lifting position, the conveying line at the front end of the stacking device conveys the first material to the horizontal conveying device 321 of the first horizontal sliding table 32, the first horizontal sliding table 32 carries the first material and is switched to a standby position, the second horizontal sliding table 32 is switched to a lifting position, the conveying line at the front end of the stacking device conveys the second material to the horizontal conveying device 321 of the second horizontal sliding table 32, the lifting fork 23 lifts the second material and suspends it above the horizontal conveying device 321 of the second horizontal sliding table 32, the second horizontal sliding table 32 is switched to a standby position, and the first horizontal sliding table 32 carries the first material and is switched to a lifting position. At this time, the second material is located directly above the first material, the lifting fork 23 is lowered and the second material is stacked on the first material.

[0035] Specifically, as Figure 3 The lifting mechanism 20 further comprises an adjusting guide rail 25 horizontally arranged and fixedly connected to the rack 10 and an adjusting sliding table 26 slidably connected to the adjusting guide rail 25, the adjusting guide rail 25 is arranged perpendicularly to the horizontal sliding rail 31, and the lifting sliding block 21 is fixedly connected to the adjusting sliding table 26. The arrangement of the adjusting guide rail 25 and the adjusting sliding table 26 enables the lifting guide rail 22 to move relative to the rack 10 in a horizontal plane, so that the lifting fork 23 can extend into or exit the bottom of the material under the adjustment of the adjusting guide rail 25 and the adjusting sliding table 26, thereby achieving the picking of the material. In order to drive the adjusting sliding table 26 to slide on the adjusting guide rail 25, the lifting mechanism 20 further comprises a lifting rack 27 fixedly connected to the rack 10, and the lifting rack 27 is parallel to the adjusting guide rail 25. The adjusting sliding table 26 is provided with a first driving motor 28, and a lifting gear meshing with the lifting rack 27 is arranged on the main shaft of the first driving motor 28. The rotation of the lifting gear driven by the first driving motor 28 can drive the adjusting sliding table 26 to move relative to the rack 10 on the adjusting guide rail 25.

[0036] Embodiment 2

[0037] In combination Figures 1 to 4As shown, the stacking device of this embodiment is schematically shown, including a frame 10, a lifting mechanism 20 and a transverse movement mechanism 30.

[0038] The lifting mechanism 20 includes a lifting block 21 and a lifting guide rail 22. The lifting block 21 is connected to the frame 10. The lifting guide rail 22 is vertically arranged and slidably connected to the lifting block 21, allowing the lifting guide rail 22 to rise or fall relative to the frame 10. A lifting fork 23 is provided at the bottom end of the lifting guide rail 22, which can fork up materials. The lifting mechanism 20 also includes a lifting piston cylinder 24. The lifting piston cylinder 24 is connected to the frame 10, and the piston of the lifting piston cylinder 24 is connected to the lifting fork 23. When the lifting piston cylinder 24 extends, the lifting fork 23 descends relative to the frame 10 via the lifting guide rail 22 and the lifting block 21. When the lifting piston cylinder 24 retracts, the lifting fork 23 rises relative to the frame 10 via the lifting guide rail 22 and the lifting block 21.

[0039] The transverse mechanism 30 includes a transverse guide rail 31 and multiple transverse slides 32. The transverse guide rail 31 is horizontally fixedly connected to the frame 10, and the transverse slides 32 are slidably connected to the transverse guide rail 31. This allows each of the multiple transverse slides 32 to move laterally relative to the frame 10. A horizontal conveying device 321 is installed on the transverse slides 32. The horizontal conveying device 321 is preferably a chain plate line conveyor for horizontal material transportation. The production equipment at the front end of the stacking equipment can convey materials to the horizontal conveying device 321, which has a horizontal conveying power to move the materials.

[0040] The movement trajectory of the lifting fork 23 intersects with the movement trajectory of the transverse slide 32 , which enables the lifting fork 23 to lift the material on the transverse slide 32 .

[0041] The transverse slide 32 has a lifting position and a standby position. When the transverse slide 32 is in the lifting position, it is located at the lifting mechanism 20. At this time, the production equipment at the front end of the stacking equipment can directly transport materials to the horizontal conveying device 321 of the transverse slide 32 in the lifting position via the conveyor line. The lifting fork 23 of the lifting mechanism 20 descends to fork the materials on the horizontal conveying device 321. When the transverse slide 32 is in the standby position, the transverse slide 32 slides relative to the transverse guide rail 31 and away from the lifting mechanism 20. At this time, the horizontal conveying device 321 of the transverse slide 32 is misaligned with the conveyor line at the front end of the stacking equipment. Of the multiple transverse slides 32 on the transverse guide rail 31, only one transverse slide 32 can be in the lifting position.

[0042] The stacking equipment has multiple stacking cycles, one of which operates as follows: When one of the transverse slides 32 is switched to the lifting position, the conveyor line at the front of the stacking equipment delivers the first material to the horizontal conveying device 321 of the transverse slide 32. The lifting fork 23 lifts the first material and suspends it above the horizontal conveying device 321. The conveyor line at the front of the stacking equipment delivers the second material to the horizontal conveying device 321 of the transverse slide 32. The lifting fork 23 lowers the first material above the second material, allowing the two materials to be quickly stacked.

[0043] The working principle of another stacking rhythm is as follows: taking two transverse slides 32 and two materials as an example, the two transverse slides 32 are named the first transverse slide 32 and the second transverse slide 32 respectively, and the two materials are named the first material and the second material respectively. The first transverse slide 32 switches to the lifting position state, and the conveyor line at the front end of the stacking equipment transports the first material to the horizontal conveying device 321 of the first transverse slide 32. The first transverse slide 32 switches to the standby position state with the first material, and the second transverse slide 32 switches to the lifting position state. The conveyor line at the front end of the stacking equipment transports the second material to the horizontal conveying device 321 of the second transverse slide 32. The lifting fork 23 lifts the second material and selects it above the horizontal conveying device 321 of the second transverse slide 32. The second transverse slide 32 switches to the standby position state, and the first transverse slide 32 switches to the lifting position state with the first material. At this time, the second material is located directly above the first material, and the lifting fork 23 descends and stacks the second material on the first material.

[0044] Specifically, the lifting mechanism 20 further includes an adjustment rail 25 that is horizontally arranged and fixedly connected to the frame 10 and an adjustment slide 26 that is slidably connected to the adjustment rail 25. Figure 3 As shown, the adjustment guide rail 25 is arranged perpendicular to the transverse guide rail 31, and the lifting slider 21 is fixedly connected to the adjustment slide 26. The arrangement of the adjustment guide rail 25 and the adjustment slide 26 allows the lifting guide rail 22 to move relative to the frame 10 in a horizontal plane, so that the lifting fork 23 can extend into or out of the bottom of the material under the adjustment of the adjustment guide rail 25 and the adjustment slide 26, thereby achieving the forked material. In order to drive the adjustment slide 26 to slide on the adjustment guide rail 25, the lifting mechanism 20 also includes a lifting rack 27 fixedly connected to the frame 10, and the lifting rack 27 is parallel to the adjustment guide rail 25. The adjustment slide 26 is provided with a first drive motor 28. The main shaft of the first drive motor 28 is provided with a lifting gear that meshes with the lifting rack 27. The first drive motor 28 drives the lifting gear to rotate, thereby driving the adjustment slide 26 to move on the adjustment guide rail 25 relative to the frame 10.

[0045] Furthermore, two lifting mechanisms 20 are provided, and the lifting forks 23 of the two lifting mechanisms 20 are arranged opposite each other. The two lifting forks 23 are moved by their respective lifting gears and lifting racks 27. The two lifting forks 23 move toward each other to jointly pick up the material from both sides, and the two lifting forks 23 move away from the material to the sides of the material. The two lifting mechanisms 20 can effectively increase the liftable weight and ensure the stability of the material during lifting.

[0046] The lifting fork 23 comprises a connecting rod 231 and multiple fork plates 232. Both the fork plates 232 and the connecting rod 231 are arranged horizontally. The fork plates 232 and the connecting rod 231 are perpendicular to each other. The connecting rod 231 is fixedly connected to the lifting rail 22. The multiple fork plates 232 are parallel to each other and arranged sequentially on the same side of the fork plates 232. The connecting rod 231 is used to connect the fork plates 232 to the lifting rail 22. The multiple fork plates 232 can support materials simultaneously to prevent them from shaking during the lifting or lowering process.

[0047] Furthermore, a transverse sliding member 322 is provided at the bottom of the transverse slide 32. The transverse sliding member 322 is slidably connected to the transverse guide rail 31. The transverse sliding member 322 may be a plurality of sliders, and its function is to achieve a slidable connection between the transverse slide 32 and the transverse guide rail 31. To improve the movement stability of the transverse slide 32, there are two transverse guide rails 31. Transverse sliding members 322 are provided at both ends of the bottom of the transverse slide 32. The two transverse sliding members 322 are slidably connected to the two transverse guide rails 31, respectively.

[0048] Combine Figure 2 and Figure 4 As shown, a horizontally mounted transverse rack 33 is provided on the frame 10, parallel to the transverse guide rail 31. A second drive motor 323 is provided at the bottom of the transverse slide 32. The main shaft of the second drive motor 323 is equipped with a transverse gear that engages with the transverse rack 33. The second drive motor 323 drives the transverse gear to rotate, thereby driving the transverse slide 32 to move along the transverse rack 33 (and transverse guide rail 31) relative to the frame 10. In this embodiment, the transverse guide rail 31 is located below the lifting mechanism 20.

[0049] To sum up, the transverse slide 32 can move transversely relative to the frame 10 after receiving the material, and the lifting fork 23 can lift the material through the lifting guide rail 22 and the lifting slider 21 so that two materials can be stacked, and multiple transverse slides 32 are connected to the frame 10 through the transverse guide rail 31, so that the material stacking rhythm can be adaptively adjusted with the production rhythm or the subsequent transportation rhythm of the stacking equipment, and the applicability is wider.
