[0002] Material stacking stations are widely used in manufacturing, logistics, retail and other fields. In the manufacturing industry, material stacking stations are used to store raw materials, semi-finished products and finished products to ensure the continuous supply of production lines. In the logistics industry, as an important part of the warehousing and sorting center, material stacking stations are responsible for the reception, storage, sorting and outbound delivery of goods. In the retail industry, material stacking stations are used to store and manage various types of goods to meet the replenishment needs of stores. The development of material stacking stations has undergone a transformation from manual operation to automation and intelligence. In the early days, material stacking mainly relied on manual operation, which was inefficient and prone to errors. With the continuous advancement of logistics technology, advanced equipment such as automated stereoscopic warehouses and stackers have gradually been applied to material stacking stations, greatly improving storage and handling efficiency. In recent years, with the rapid development of technologies such as the Internet of Things, big data, and artificial intelligence, material stacking stations are gradually developing in the direction of intelligence and networking, achieving more efficient and accurate material management.

[0032] Embodiment 2: This embodiment is intended to promote the solution of the problem that there is no restriction on the right side of the cargo box 61, which may cause the cargo box 61 to tilt to the right during the lifting process. This embodiment is an improvement made on the basis of embodiment 1.

[0033] A second hydraulic oil tank 2 is provided inside the support arm 12, and a second sealing block 23 is slidably connected inside the second hydraulic oil tank 2.

A hose 35 is connected to one end of the second hydraulic oil tank 2, and the other end of the hose 35 is connected to the first hydraulic oil tank 32. Through the design of the hose 35, the first hydraulic oil tank 32 and the second hydraulic oil tank 2 can be connected, so that the hydraulic oil in the second hydraulic oil tank 2 can enter the first hydraulic oil tank 32 through the hose 35.
[0034] A first slide rail 13 is provided on one side of the limiting slide groove 11, one end of the first slide rail 13 is connected to a first inclined slide rail 14, the other end of the first inclined slide rail 14 is connected to a second slide rail 15, the other end of the second slide rail 15 is connected to a second inclined slide rail 16, the other end of the second inclined slide rail 16 is connected to a third slide rail 17, the other end of the third slide rail 17 is connected to a third inclined slide rail 18, the other end of the third inclined slide rail 18 passes through the second slide rail 15 and is connected to a fourth slide rail 19, the other end of the fourth slide rail 19 is connected to the first slide rail 13; A sliding column 25 is provided on one side of the left end of the first rack rod 21 , and the sliding column 25 is used for sliding connection with the first slide rail 13 , the first inclined slide rail 14 , the second slide rail 15 , the second inclined slide rail 16 , the third slide rail 17 , the third inclined slide rail 18 and the fourth slide rail 19 .
[0035] A first guide rod 118 is provided at the junction of the first slide rail 13, the first inclined slide rail 14 and the fourth slide rail 19, one end of the first guide rod 118 is rotatably connected to the inside of the stacker 1, one end of the first guide rod 118 is provided with a first torsion spring 119, and the other end of the first guide rod 118 abuts against a first stop block 120; When the other end of the first guide rod 118 abuts against one side of the first stopper 120 , the sliding post 25 slides from the first slide rail 13 into the first inclined slide rail 14 .
[0036] A second guide rod 111 is provided at the junction of the second slide rail 15 and the third inclined slide rail 18 , one end of the second guide rod 111 is rotatably connected to the inside of the stacker 1 , one end of the second guide rod 111 is provided with a second torsion spring 112 , and the other end of the second guide rod 111 abuts against a second stop block 113 .
[0037] A limiting block 115 is provided in the third inclined slide rail 18, one end of the limiting block 115 abuts against a fourth spring 117, the fourth spring 117 is located in the stacker 1, one end of the limiting block 115 is fixedly connected to an abutting inclined rod 116, the limiting block 115 and the abutting inclined rod 116 are slidably connected to the inside of the stacker 1, the inclined surface of one end of the abutting inclined rod 116 is used to abut against the second guide rod 111, a third abutting block 114 is provided on one side of the inclined surface of the abutting inclined rod 116, the third abutting block 114 is fixedly installed in the inside of the stacker 1, and the third abutting block 114 is used to limit the position of the second abutting block 113; When one end of the second guide rod 111 collides with the inclined surface of one end of the oblique rod 116, the limiting block 115 opens the restriction on the third inclined slide rail 18. Through the design of the second guide rod 111 and the limiting block 115, the sliding column 25 will not slide into the third inclined slide rail 18 when sliding through the third inclined slide rail 18 in the second slide rail 15, thereby preventing the sliding column 25 from deviating from the predetermined track.
[0038] The right end of the resistance arm 4 is slidably connected to a sliding resistance block 42, one end of the sliding resistance block 42 is in resistance to a first spring 43, the first spring 43 is located inside the resistance arm 4, and the other end of the sliding resistance block 42 is used to resist the other side of the cargo box 61. The design of the resistance arm 4 and the sliding resistance block 42 to resist the right side of the cargo box 61 ensures that the cargo box 61 will not tilt to the right during the lifting process.
[0039] See Figure 3 When the support arm 12 drives the support frame 6 and the cargo box 61 to lift upward, the sliding column 25 at one end of the first rack rod 21 will first slide in the first slide rail 13. Figure 5 When the sliding column 25 slides to the junction of the first slide rail 13, the first inclined slide rail 14 and the fourth slide rail 19, under the guidance of the first guide rod 118, the sliding column 25 slides into the first inclined slide rail 14. As the support arm 12 continues to lift up, the sliding column 25 slides to the right in the first inclined slide rail 14. When the sliding column 25 slides, it drives the first rack rod 21 to slide to the right. When the first rack rod 21 slides to the right, the rack at the right end of the first rack rod 21 drives the first gear 31, so that the first gear 31 rotates. When the first gear 31 rotates, it drives the auxiliary arm 3 and the interference arm 4 to rotate together. See Figure 8When the first rack rod 21 slides to the right, it drives the connecting rod 22 to slide together. When the connecting rod 22 slides, it drives the second sealing block 23 to slide in the second hydraulic oil tank 2, squeezes the hydraulic oil in the second hydraulic oil tank 2, and makes the hydraulic oil in the second hydraulic oil tank 2 enter the first hydraulic oil tank 32 through the hose 35. As the hydraulic oil continues to push the first sealing block 33, the first sealing block 33 drives the fixed rod 34 to slide together, so that the fixed rod 34 drives the interference arm 4 to extend to the right together, and drives the interference arm 4 to move to the right, so that the second gear 41 is meshed with the second rack rod 36, so that the second gear 41 drives the interference arm 4 is rotated, and the design of the resistance arm 4 extending and rotating at the same time makes the resistance arm 4 drive the sliding resistance block 42 to move to the upper right side of the cargo box 61, so that the sliding resistance block 42 can resist as far as possible to the upper right side of the cargo box 61, and the same resistance force acts on the upper right side of the cargo box 61 as far as possible. Compared with the direct resistance method to the bottom of the cargo box 61, under the condition of the same resistance force, the method of resisting as far as possible to the upper part of the cargo box 61 is adopted, which effectively improves the support stability of the cargo box 61, and both sides of the cargo box 61 are restricted, which can make the position of the cargo box 61 more stable, and make the cargo box 61 more stable during the lifting process.
[0040] See Figure 4 After the sliding block 42 restricts the right side of the cargo box 61, as the support arm 12 continues to rise, the sliding column 25 slides in the second slide rail 15. When the sliding column 25 slides to the junction of the second slide rail 15 and the third inclined slide rail 18, the sliding column 25 is prevented from sliding into the third inclined slide rail 18 under the restriction of the second guide rod 111 and the limiting block 115, and the sliding column 25 is prevented from deviating from the predetermined track.
[0041] In this embodiment, the sliding of the first rack rod 21 drives the auxiliary arm 3 and the abutment arm 4 to rotate, so that the sliding abutment 42 can abut the right side of the cargo box 61, and the fixed column 110 and the sliding abutment 42 simultaneously restrict both sides of the cargo box 61, which can prevent the cargo box 61 from shaking during the lifting process, prevent the position of the cargo box 61 from being offset, and make the cargo box 61 more stable during the lifting process; Moreover, the sliding column 25 slides into the first inclined slide rail 14 when the support arm 12 is just lifted up. Through such a design, the position of the cargo box 61 can resist the right side of the cargo box 61 as soon as it is lifted up, thereby preventing the cargo box 61 from shaking and deviating when it is lifted too high, and further preventing the cargo box 61 from shaking during the lifting process.
[0042] Embodiment 3: This embodiment is intended to promote the solution of the problem that the contact between the support arm 12 and the groove of the support frame 6 is not stable enough. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 11 , transverse support blocks 5 are slidably arranged on both sides of the support arm 12, one side of the transverse support block 5 is used to contact the support frame 6, and the second springs 51 are contacted on both sides inside the transverse support block 5, and the other side of the second spring 51 contacts the inside of the support arm 12, and a contact inclined surface 52 is opened on one side inside the transverse support block 5.
[0043] The first rack rod 21 is provided with an interfering inclined block 24 , and the inclined surface of the interfering inclined block 24 is used to interfere with the interfering inclined surface 52 .
[0044] A limiting slide rail 55 is provided inside the transverse support block 5, and a resistance block 53 is slidably connected to the limiting slide rail 55. The resistance block 53 is slidably connected to the inside of the transverse support block 5. One side of one end of the resistance block 53 is in resistance to a longitudinal support block 56. A third spring 54 is provided at one end of the longitudinal support block 56. The third spring 54 is located inside the transverse support block 5. The longitudinal support block 56 is slidably connected to the transverse support block 5. An inclined surface is provided on one side of the resistance block 53 that is in resistance to the longitudinal support block 56.
[0045] See Fig.10 and Fig.11 When the first rack rod 21 slides to the right, it will drive the oblique block 24 to slide together. When the oblique block 24 slides to the cross support block 5, the inclined surface of the oblique block 24 will conflict with the oblique surface 52, so that the cross support block 5 slides to both sides, and at the same time, the second spring 51 will be deformed. The second spring 51 can assist the subsequent cross support block 5 to return to its original position. Since the oblique block 53 is located inside the cross support block 5 and the two are slidably connected, the cross support block 5 can slide to both sides at the same time. , will drive the resistance block 53 to slide together. When the horizontal support block 5 drives the resistance block 53 to resist the two sides of the groove of the support frame 6, the resistance block 53 will contact the groove wall of the support frame 6 before, so that the resistance block 53 slides into the horizontal support block 5 through the limiting slide rail 55. The design of the limiting slide rail 55 can limit the position of the resistance block 53 to prevent the position of the resistance block 53 from being offset. At the same time, the third spring 54 can subsequently drive the longitudinal support block 56 and the resistance block 53 to return to their original positions. The third spring 54 is a tension spring. When the resistance block 53 slides into the transverse support block 5, the inclined surface at one end of the resistance block 53 resists the inclined surface at one end of the longitudinal support block 56, so that the longitudinal support block 56 can slide out of the transverse support block 5. At this time, the longitudinal support block 56 has slid out of the support arm 12, so that the longitudinal support block 56 can slide to be flush with one side of the support arm 12, thereby increasing the contact area with the groove of the support frame 6. At the same time, the transverse support block 5 supports the groove of the support frame 6 laterally, so that the transverse support block 5 on the support arm 12 can be stuck in the groove of the support frame 6.
[0046] When the cargo box 61 is lifted and needs to be put down, the support arm 12 needs to be slightly lifted first, so that the sliding post 25 can slide into the second inclined slide rail 16, so that the sliding post 25 can slide into the third slide rail 17 through the second inclined slide rail 16, and at the same time, the first rack rod 21 will continue to slide to the right. It should be noted that a second guide rod 111 for allowing the sliding post 25 to slide in one direction is provided between the second inclined slide rail 16 and the third slide rail 17. The same structure as that at the second guide rod 111 is used to allow the sliding post 25 to slide in one direction, so that the sliding post 25 can only slide from the second inclined slide rail 16 into the third slide rail 17, and cannot slide in the opposite direction, thereby increasing the resistance force of the sliding stop block 42 on the right side of the cargo box 61. At this time, the sliding stop block 42 will slide into the resistance arm 4 to prevent damage to the surface of the cargo box 61. Then the support arm 12 starts to slide downward, and the sliding post 25 slides in the third slide rail 17. When the sliding post 25 slides into the third inclined slide rail 18, Figure 4 At this time, the sliding column 25 will resist the second guide rod 111, causing the second guide rod 111 to rotate. While the second guide rod 111 rotates, it resists the inclined surface of the resisting inclined rod 116, causing the resisting inclined rod 116 to slide into the interior of the stacker 1. Figure 6 , while the oblique rod 116 slides, the limiting block 115 is driven to slide together, so that the limiting block 115 opens the restriction on one side of the third inclined slide rail 18, so that the sliding column 25 can slide into the other end of the third inclined slide rail 18. At the same time, the design of the second torsion spring 112 can provide power for the second guide rod 111 to return to its original position later. The design of the fourth spring 117 can enable the limiting block 115 to return to its original position later. The third blocking block 114 can prevent the second guide rod 111 from excessive rotation. It should be noted that the elastic force of the second torsion spring 112 is sufficient to restore the second guide rod 111 to its original position, and can prevent the oblique rod 116 from jamming the second guide rod 111.
[0047] As the support arm 12 continues to slide down, the sliding column 25 slides from the third inclined slide rail 18 into the fourth slide rail 19. At this time, the auxiliary arm 3 and the resistance arm 4 have returned to their original positions, and the sliding resistance block 42 no longer resists the right side of the cargo box 61. When the sliding column 25 slides to the first guide rod 118, the first guide rod 118 opens the channel through the resistance of the sliding column 25 to the first guide rod 118, so that the sliding column 25 slides back into the first slide rail 13.
[0048] In the present embodiment: by the interference of the horizontal support block 5 on both sides of the groove of the support frame 6 and the increase of the contact area with the groove of the support frame 6 by the longitudinal support block 56, the support frame 6 can be stably fixed on the support arm 12, and the support frame 6 can be prevented from shifting during the lifting process. By fixing the support frame 6, the stability of the cargo box 61 when being lifted can be further increased, and the safety during stacking can be further increased.
