Description

Technical Field

[0001] This invention belongs to the field of material stacking technology, specifically relating to a lift for stacking box-shaped materials in batches for packing. Background Technology

[0002] When packing boxed materials, the materials first need to be stacked in a vertical row, and then an external pushing mechanism (such as a forklift) is used to push the stacked materials into the box. Currently, materials are generally stacked manually or by mechanical equipment. Even when using mechanical equipment, human assistance is still needed to ensure that the materials are stacked neatly so that the pushing mechanism can push the stacked materials into the box. However, when dealing with large-scale material production and transportation, relying solely on human assistance to ensure stacking quality is far from meeting production needs. Therefore, a device that can achieve fully automated material stacking is needed, and in view of this, the present invention is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting machine for stacking box-shaped materials in batches for packing materials, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a lifting platform for stacking box-shaped materials in batches for packing, comprising a first conveying trolley and a second conveying trolley, each having a conveying device correspondingly arranged on one side; an automatic stacking mechanism is arranged between the first and second conveying trolleys; each of the first and second conveying trolleys includes a driving mechanism and a loading mechanism disposed on top of the driving mechanism; the loading mechanism includes a transmission plate, and three electric rollers are mounted on the top of the transmission plate; the three electric rollers are driven by a motor. The wheel assembly drives the chain to rotate synchronously; the automatic stacking mechanism includes a fixed base, with a left stacking plate and a right stacking plate symmetrically arranged on both sides below the fixed base, and the left and right stacking plates can be raised and lowered in a crisscross manner in the vertical direction. Four support plates are fixedly connected to the bottom opposite sides of the left and right stacking plates, and the three gaps formed between the four support plates are adapted to three electric rollers. The inner side of the left and right stacking plates is connected to a push plate that can reciprocate in the horizontal direction, and the height of the push plate is the same as the height of the left or right stacking plate.

[0005] Preferably, the fixing base has a rectangular frame structure, with a second motor fixedly installed in the middle of its inner side. A second shaft is fixedly connected to the motor shaft of the second motor. The end of the second shaft is rotatably connected to the inner wall of the fixing base. A connecting rod is fixedly sleeved in the middle of the second shaft. Slide grooves are provided on both sides of the connecting rod. The tops of the left and right stacking plates extend into the corresponding slide grooves on both sides of the connecting rod and are hinged and slidably connected thereto. Limiting rods are connected vertically to the outer sides of the tops of the left and right stacking plates. The limiting rods pass through the fixing base and are slidably connected thereto.

[0006] Preferably, a fixing plate is fixedly connected to the outer wall of both the left and right stacking plates. An electric telescopic rod is provided inside the fixing plate. The movable end of the electric telescopic rod passes through the corresponding left and right stacking plates in the horizontal direction and is fixedly connected to the push plate.

[0007] Preferably, an end face gear is fixedly connected to the bottom of the transmission plate. The teeth of the end face gear are distributed in a 90-degree ring at the bottom. A fixed ring is rotatably connected to the outer side of the end face gear. Multiple fixed rods are fixedly connected to the bottom end of the fixed ring in the vertical direction. A connecting plate is provided below the transmission plate. The bottom end of the fixed rod is fixedly connected to the upper surface of the connecting plate. The drive mechanism includes an electric trolley. The connecting plate is placed on the electric trolley. A first shaft is provided below the end face gear. A baffle is fixedly sleeved in the middle of the first shaft. Mounting plates are rotatably connected to both ends of the first shaft. The two mounting plates are fixedly connected to the two connecting plates respectively. A gear is also fixedly sleeved on one side of the first shaft located on the baffle. The gear meshes with the end face gear. A first motor is provided on the outer side of any mounting plate. The motor shaft of the first motor is fixedly connected to the first shaft. The bottom of the first motor is fixedly connected to the connecting plate through a connector. A stop block that cooperates with the baffle is fixedly installed on the top of the electric trolley. When the first and second conveying trolleys move, the baffle is always located on the side of the forward direction of the stop block.

[0008] This invention also proposes a method for stacking boxed materials in batches, using the aforementioned elevator for stacking boxed materials in batches. The method is as follows: the first material carried on the conveying device is conveyed forward to three electric rollers in the carrying mechanism. The first conveying trolley carrying the first material moves towards the automatic stacking mechanism to the bottom of the right stacking plate. As the right stacking plate moves upward, its bottom support plate passes through the gap between the three electric rollers, causing the first material to separate from the first conveying trolley. When the left and right stacking plates move to the point where their bottoms are level, the first conveying trolley starts to return to the initial position. When the first conveying trolley moves beyond the left stacking plate, the right stacking plate continues to move upward, and the left stacking plate continues to move downward to the limit position.

[0009] As the first conveyor trolley returns to its initial position, the second conveyor trolley carrying the second material moves toward the automatic stacking mechanism to the bottom of the left stacking plate. At this time, the pusher plate on the right stacking plate pushes the first material onto the second material. Then the pusher plate returns to its initial position. The left stacking plate carrying the first and second materials moves upward, while the right stacking plate moves downward. When the left and right stacking plates move to the same level at their bottoms, the second conveyor trolley starts to return to its initial position. When the second conveyor trolley moves past the right stacking plate, the left stacking plate continues to move upward, and the right stacking plate continues to move downward to its limit position.

[0010] When the first conveyor trolley carrying the third material moves toward the bottom of the right stacking plate in the direction of the automatic stacking mechanism, the pusher plate on the left stacking plate pushes the first and second materials together onto the third material. Then the pusher plate returns to the initial position, and the above steps are repeated to gradually stack the goods into a vertical row.

[0011] Compared with the prior art, the present invention provides a lifting platform for stacking box-shaped materials in batches for packing materials, which has the following advantages:

[0012] (1) In this invention, the first and second conveying trolleys cross-convey materials to the right and left stacking plates respectively, increasing the material stacking speed. The drive mechanism and the electric trolley are detachably connected, allowing the electric trolley to be removed for repair if it malfunctions. Simultaneously, the baffle on the transport trolley must rotate to align with the direction of movement before the electric trolley can move the upper carrying mechanism and materials. That is, after the first conveying trolley is loaded with goods, the electric roller must rotate 90 degrees to align with the support plate before the electric trolley can move the upper carrying mechanism and materials. This prevents damage to the device caused by the electric roller directly contacting the support plate without rotating 90 degrees after contacting the goods on the conveying device, thus ensuring safety. The entire device in this invention can efficiently stack materials sequentially, operates reliably, and ensures the stacking efficiency and quality, improving the automation level of material stacking and meeting production needs.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0024] Please see Figures 1-15 This invention proposes a lifting machine for stacking box-shaped materials in batches for packaging. It includes a first conveying trolley 1 and a second conveying trolley 2. A conveying device 3 is provided on one side of both the first conveying trolley 1 and the second conveying trolley 2. An automatic stacking mechanism 4 is provided between the first conveying trolley 1 and the second conveying trolley 2. Both the first conveying trolley 1 and the second conveying trolley 2 include a driving mechanism 5 and a carrying mechanism 6 provided on the top of the driving mechanism 5. The carrying mechanism 6 includes a transmission plate 9. Three electric rollers 10 are installed on the top of the transmission plate 9. The three electric rollers 10 rotate synchronously by a motor driving a gear set to drive a chain. The three electric rollers 10 are at the same height as the conveying device 3. The material is conveyed onto the electric rollers 10 by the friction generated between the electric rollers 10 and the material. The automatic stacking mechanism 4 includes a fixed base 20. A left stacking plate 21 and a right stacking plate 22 are symmetrically arranged on both sides of the lower part of the fixed base 20. The left stacking plate 21 and the right stacking plate 22 can be raised and lowered in a cross manner in the vertical direction. Four support plates 23 are fixedly connected to the bottom opposite sides of the left stacking plate 21 and the right stacking plate 22. The three gaps formed between the four support plates 23 are adapted to the three electric rollers 10. When the left stacking plate 21 or the right stacking plate 22 moves upward, the four support plates 23 pass through the gaps between the three electric rollers 10 to transfer the material to the stacking plate. The inner side of the left stacking plate 21 and the right stacking plate 22 is connected to a push plate 24 that can reciprocate in the horizontal direction. The height of the push plate 24 is the same as the height of the left stacking plate 21 or the right stacking plate 22. Through the cross-movement of the push plate 24 with the two stacking plates, the material on the left stacking plate 21 or the right stacking plate 22 can be pushed and stacked together.

[0025] Specifically, such as Figure 6As shown, the fixed base 20 in this embodiment has a rectangular frame structure. A second motor 31 is fixedly installed in the middle of its inner side. A second shaft 30 is fixedly connected to the motor shaft of the second motor 31. The end of the second shaft 30 is rotatably connected to the inner wall of the fixed base 20. A connecting rod 28 is fixedly sleeved in the middle of the second shaft 30. Slide grooves 29 are provided on both sides of the connecting rod 28. The tops of the left stacking plate 21 and the right stacking plate 22 extend into the corresponding slide grooves 29 on both sides of the connecting rod 28 and are hinged and slidably connected thereto. Limiting rods 27 are vertically connected to the outer top of both stacked plate 21 and right stacked plate 22. The limiting rods 27 pass through the fixed base 20 and are slidably connected to it. When the second motor 31 drives the second shaft 30 to rotate, the connecting rod 28 rotates synchronously with the second shaft 30. Under the action of the limiting rods 27, the left stacked plate 21 and right stacked plate 22 move vertically along the fixed base 20. At the same time, the top of the left stacked plate 21 and right stacked plate 22 slides along the groove 29 of the connecting rod 28.

[0026] Furthermore, in this embodiment, the reciprocating motion of the push plate 24 in the horizontal direction is driven by the electric telescopic rod 25. Specifically, a fixing plate 26 is fixedly connected to the outer wall of the left stacking plate 21 and the right stacking plate 22. The electric telescopic rod 25 is provided inside the fixing plate 26. The movable end of the electric telescopic rod 25 passes through the corresponding left stacking plate 21 and right stacking plate 22 in the horizontal direction and is fixedly connected to the push plate 24.

[0027] like Figures 3-5As shown, an end face gear 11 is fixedly connected to the bottom of the transmission plate 9. The teeth of the end face gear 11 are distributed in a 90-degree ring at the bottom. A fixing ring 12 is rotatably connected to the outer side of the end face gear 11. Multiple fixing rods 13 are fixedly connected to the bottom end of the fixing ring 12 in the vertical direction. A connecting plate 14 is provided below the transmission plate 9. The bottom end of the fixing rods 13 is fixedly connected to the upper end face of the connecting plate 14. The drive mechanism 5 includes an electric trolley 7. The connecting plate 14 is placed on the electric trolley 7. The drive mechanism 5 and the loading mechanism 6 are connected in a detachable manner. When the electric trolley 7 malfunctions, it can be directly removed for repair. A first shaft 15 is provided below the end face gear 11. A baffle 17 is fixedly sleeved in the middle of the first shaft 15. Mounting plates 16 are rotatably connected to both ends of the first shaft 15. The two mounting plates 16 are fixedly connected to two connecting plates 14 respectively. A gear 18 is also fixedly sleeved on the first shaft 15 on one side of the baffle 17. The gear 18 meshes with the end face gear 11. A first motor 19 is provided on the outside of any mounting plate 16. The motor shaft of the first motor 19 is fixedly connected to the first shaft 15. The bottom of the first motor 19 is fixedly connected to the connecting plate 14 through a connector. A stop block 8 that cooperates with the baffle 17 is fixedly installed on the top of the electric trolley 7. When the first conveying trolley 1 and the second conveying trolley 2 move, the baffle 17 is always located on the side of the forward direction of the stop block 8. In the application, the three electric rollers 10 on the loading mechanism 6 are initially parallel to the rollers on the conveying device 3. When the material is conveyed to the stacking plate, the three electric rollers 10 need to be rotated 90 degrees. In order to prevent the electric rollers 10 from directly docking with the support plate 23 without rotating 90 degrees after docking with the goods on the conveying device 3, causing damage to the device, this application fixes a stop block 8 that cooperates with the baffle 17 on the top of the electric trolley 7. Only when the first motor 19 drives the three electric rollers 10 to rotate 90 degrees will the position of the support plate 23 be corresponding, and the baffle 17 will also rotate to the side of the forward direction of the stop block 8 due to the drive of the first motor 19. The electric trolley 7 drives the stop block 8 to move, and the stop block 8 pushes the baffle 17 to push the loading mechanism 6 to move.

[0028] This invention discloses a lifting machine for stacking box-shaped materials in batches for packing materials. In specific use, the fixed base 20 can be fixed to the external crossbeam through the mounting holes on the outside. Figure 1 This represents the initial position of each structure in the device. Figure 2The initial positions of the first conveying trolley 1 and the second conveying trolley 2 are shown. The electric roller 10 in the first conveying trolley 1 is started, and the first material 32 is conveyed onto the electric roller 10 via the conveying device 3 on one side of the first conveying trolley 1. The electric roller 10 in the first conveying trolley 1 is then turned off. Next, the first motor 19 in the first conveying trolley 1 is started. The first motor 19 drives the first shaft 15 to rotate via the motor shaft. The first shaft 15 drives the baffle 17 and gear 18 to rotate 180 degrees clockwise. The first motor 19 is then turned off. The inner side of the baffle 17 contacts the side of the stop block 8 closest to the forward direction. The gear 18 drives the transmission plate 9 and the electric roller 10 to rotate via the end face gear 11, thereby rotating the first material 32 90 degrees (at this point, the state is as follows). Figure 7 (As shown).

[0029] Then, the electric trolley 7 in the first conveying trolley 1 is started. The electric trolley 7 drives the stop block 8 to move towards the automatic stacking mechanism 4. The stop block 8 pushes the baffle 17 to move, which in turn pushes the carrying mechanism 6 to move, thus carrying the first material 32 towards the automatic stacking mechanism 4. After the first material 32 is located at the bottom of the right stacking plate 22, the electric trolley 7 is turned off. At this time, the electric roller 10 is located in the gap formed by the support plate 23, and the height of the electric roller 10 is slightly greater than that of the support plate 23 (the state at this time is as follows). Figure 8 , 9 (As shown).

[0030] Then, the second motor 31 is started. The second motor 31 drives the second shaft 30 and connecting rod 28 to rotate via the motor shaft, thereby moving the left stacking plate 21 and the right stacking plate 22. The left stacking plate 21 and the right stacking plate 22 slide up and down within the fixed seat 20 via the limiting rod 27. The left stacking plate 21 moves downward, and the right stacking plate 22 moves the first material 32 upward, causing the first material 32 to detach from the first conveying trolley 1. When the bottom ends of the left stacking plate 21 and the right stacking plate 22 are flush (at this time, the state is as follows...), the second motor 31 is started. Figure 10 (As shown), temporarily shut down the second motor 31.

[0031] Start the first motor 19 in the first conveying trolley 1, causing the first shaft 15 to drive the baffle 17 and gear 18 to rotate 180 degrees counterclockwise, and then turn off the first motor 19. At this time, the inner side of the baffle 17 contacts the side of the stop block 8 closest to the forward direction, and the gear 18 drives the transmission plate 9 and the electric roller 10 to rotate 90 degrees through the end face gear 11, returning to the initial state. Then start the electric trolley 7 in the first conveying trolley 1, and the electric trolley 7 drives the stop block 8 to move to the left. The stop block 8 pushes the baffle 17 to move, which in turn pushes the loading mechanism 6 to move, so that the electric roller 10 approaches the corresponding conveying device 3, that is, returns to the initial position, and then turns off the electric trolley 7, waiting to load the next material. At the same time, when the first conveying trolley 1 moves to the left and passes the left stacking plate 21, the second motor 31 is started again, so that the left stacking plate 21 and the right stacking plate 22 continue to move a certain distance before turning off (at this time the state is as follows). Figure 11 (As shown). Simultaneously, as the first conveyor trolley 1 moves to the left, the second conveyor trolley 2 will operate in the same manner as the first conveyor trolley 1 to load the second material 33, and the material will be moved between the left stacking plate 21 and the right stacking plate 22. Figure 11 At the position shown, the second conveying trolley 2 carries the second material 33 and moves it towards the automatic stacking mechanism 4, conveying the second material 33 to the bottom end of the left stacking plate 21 (at this time, the state is as shown). Figure 12 (As shown).

[0032] Then activate the electric telescopic rod 25 on one side of the right stacking plate 22, causing the pusher plate 24 to push the first material 32 onto the second material 33 (at this time, the state is as follows). Figure 13 (As shown), the electric telescopic rod 25 then moves the pusher plate 24 back to its original position. Then, the second motor 31 is started, causing the left stacking plate 21 to carry the second material 33 and the first material 32 upwards, and the right stacking plate 22 to move downwards. Similarly, when the bottom ends of the left and right stacking plates 21 and 22 are aligned, the second motor 31 is temporarily shut off. Using the same operation as the first conveyor trolley 1, the inner side of the baffle 17 in the second conveyor trolley 2 contacts the side of the stop block 8 closest to the forward direction. The electric roller 10 rotates 90 degrees, returning to the initial state. Then, the second conveyor trolley 2 moves towards the corresponding conveying device 3, returning to its initial position. Simultaneously, when the second conveyor trolley 2 moves to the right and passes the right stacking plate 22, the second motor 31 is started again, causing the left and right stacking plates 21 and 22 to continue moving a certain distance before shutting off. Afterwards, the first and second conveyor trolleys 1 and 2 will continue to convey materials into the right stacking plate 22 and left stacking plate 21 using the above operating procedure, which will not be repeated below.

[0033] The first conveyor trolley 1 carries the third material 34 and positions it at the bottom of the right-side stacking plate 22 (at this point, the state is as follows). Figure 14As shown), activate the electric telescopic rod 25 on one side of the left stacking plate 21, causing the pusher plate 24 to push the second material 33 and the first material 32 onto the third material 34 (at this time, the state is as shown). Figure 15 (As shown in the figure), then the electric telescopic rod 25 drives the push plate 24 to move back to its original position. Then, the above operation process is repeated to gradually stack the goods into a vertical row. Then, using an external pushing mechanism (not shown in the figure), the stacked materials are pushed from one side into the large outer box (not shown in the figure). The above process is repeated until the large outer box is full.
