Description

Technical Field

[0001] This utility model relates to the field of logistics warehousing and automation technology, and in particular to a pallet sorting machine. Background Technology

[0002] In the fields of logistics warehousing and automated production, pallets serve as the core carrier for cargo storage and transfer, and their palletizing and splitting efficiency directly affects the stability and safety of the overall operation process. Pallet sorting machines are a type of automated equipment widely used in warehouses, distribution centers, and production lines. Their core function is to automatically stack individual pallets or split entire pallets through mechanical structures or control systems, thereby optimizing space utilization and improving material flow efficiency.

[0003] However, traditional pallet sorting machines generally suffer from a technical bottleneck during operation: due to slight deviations in pallet size, weight distribution, and input position, insufficient positioning accuracy during stacking can lead to accumulated alignment errors between pallets. Specifically, when a pallet is placed in the target position, if there is a misalignment, the edges of adjacent pallets cannot fully fit together, resulting in a stepped misalignment; the contact area between layers of misaligned pallet stacks is reduced, decreasing load-bearing capacity, and especially in multi-layer stacks, uneven local stress can easily cause tilting; skewed pallet stacks may collapse during subsequent handling or storage due to vibration, external impact, or shift in center of gravity, causing damage to goods or even personal injury.

[0004] Therefore, there is an urgent need for a pallet coder that can guide and prevent offset. Utility Model Content

[0005] The purpose of this utility model is to provide a pallet sorting machine to ensure that pallets do not shift during the stacking process, thereby reducing the risk of pallets falling due to instability caused by skewed pallets.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A pallet sorting machine includes:

[0008] First rack;

[0009] The second rack, together with the first rack, forms a space for stacking multiple trays. The first rack and the second rack are slidably connected to adjust the size of the space.

[0010] The clamping assembly includes two opposing clamping members, which are respectively disposed on the first frame and the second frame. The two clamping members can be brought close to each other so that multiple trays can be neatly stacked by clamping action.

[0011] As an optional solution for a pallet sorting machine, the clamping assembly includes two first driving members disposed on the first frame and the second frame. The clamping member is strip-shaped and extends along the stacking direction of the pallet. The first driving members are pulsatorically connected to the clamping member. The two first driving members are respectively used to drive the two clamping members to move closer to each other or further away from each other.

[0012] As an optional solution for a pallet barcode scanner, the clamping assembly further includes two guide members extending along the relative movement direction of the clamping members, with the two clamping members slidably connected to the two guide members respectively.

[0013] As an optional solution for a pallet barcode scanner, the first frame and the second frame together form a U-shaped structure. The first frame is provided with a first connecting part, and the second frame is provided with a second connecting part. The first connecting part and the second connecting part are slidably connected.

[0014] As an alternative solution for a pallet barcode scanner, one of the first connecting part and the second connecting part is provided with a groove, and the other of the first connecting part and the second connecting part slides in the groove.

[0015] As an optional solution for a pallet barcode sorting machine, a second driving component is provided on one of the first frame and the second frame. The second driving component is connected to a first screw, and the first screw is threadedly connected to the other of the first frame and the second frame. The second driving component is used to drive the first screw to rotate so that the first frame and the second frame are relatively closer or relatively farther apart.

[0016] As an optional solution for a pallet sorting machine, guide wheels are respectively provided on the inner walls of the first frame and the second frame, and the pallet can be rotated and guided into the space by the guide wheels.

[0017] As an optional solution for a pallet sorting machine, the pallet sorting machine further includes two lifting components, which are respectively mounted on the first frame and the second frame. Each lifting component includes a third drive member and a platform that is pulsatorically connected to the third drive member. The third drive member is used to drive the platform to move along the stacking direction of the pallets. The platform is provided with rollers that can be supported on the ground and can roll along the relative movement direction of the first frame and the second frame.

[0018] As an alternative to a pallet sorting machine, the lifting assembly includes a second screw extending along the stacking direction of the pallets, a third drive unit being drivenly connected to the second screw, and a platform being drivenly connected to the second screw.

[0019] As an optional solution for a pallet sorting machine, the pallet sorting machine further includes two oppositely arranged tray insertion assemblies. Each tray insertion assembly includes a fourth drive member and a claw. The fourth drive member can drive the claw to extend and retract within the space, and the claw is used to insert the tray.

[0020] As an optional solution for a pallet sorting machine, the inserter includes an engaging part and a claw head. The engaging part engages with the fourth driving member for transmission. The fourth driving member is used to drive the engaging part to rotate, so that the claw head extends and retracts in the space. The claw head is used to insert the pallet.

[0021] As an optional solution for a pallet coding machine, the pallet coding machine further includes two oppositely arranged tray insertion assemblies, which are used to insert and pick up the pallet and are located on the platform.

[0022] Beneficial effects:

[0023] In this invention, the first and second frames are joined together to form a space for stacking multiple pallets. Pallets can be stacked sequentially within this space. The width of the space can be adjusted by moving the first and second frames closer together or further apart to accommodate pallets of different sizes. This relative movement not only adapts to pallets of different sizes but also allows for initial adjustments to the space to prevent excessive adjustment distances of the clamping components. Furthermore, clamping components are respectively installed on the inner walls of the first and second frames. By bringing the two clamping components closer together and clamping an entire row of pallets, the pallets are prevented from shifting during stacking, thus reducing the risk of instability and falling due to pallet tilting.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] Please see the appendix Figure 1 and attached Figure 2 This embodiment relates to a pallet sorting machine, which is particularly suitable for larger pallets, and is used to prevent pallets from deviating during stacking. The pallet sorting machine includes a first frame 1, a second frame 2, and a clamping assembly 3; wherein, the first frame 1 and the second frame 2 together form a space 100 for stacking multiple pallets, the first frame 1 and the second frame 2 are slidably connected to adjust the size of the space 100, and the clamping assembly 3 includes two opposing clamping members 31, which are respectively disposed on the first frame 1 and the second frame 2, and the two clamping members 31 can be brought close to each other so that multiple pallets are neatly stacked through clamping action.

[0047] Specifically, both the first frame 1 and the second frame 2 are L-shaped plate structures. When they are joined together, they form a U-shaped structure. The inner cavity of the U-shape is used to form a space 100 for stacking multiple pallets. The pallets can be stacked sequentially in the space 100. The width of the space 100 can be changed by the first frame 1 and the second frame 2 being relatively close or relatively far apart, so as to accommodate pallets of different sizes. The probability of pallet offset can be reduced by decreasing the distance between the first frame 1 and the second frame 2.

[0048] In this embodiment, a protective pad 8 is also provided at the connection part of the U-shaped structure. The protective pad 8 can be made of elastic material to prevent the tray from being damaged by impact after entering the space 100, thereby improving the protection.

[0049] Furthermore, clamping members 31 are respectively provided on the inner walls of the first frame 1 and the second frame 2. The two clamping members 31 are finely adjusted and clamped by being relatively close to each other, thereby ensuring that the pallets are not shifted during the stacking process and reducing the risk of falling due to instability caused by pallet tilting.

[0050] It should be noted that the relative movement of the first frame 1 and the second frame 2 can not only adapt to pallets of different sizes, but also make preliminary adjustments to the space 100 to avoid the adjustment distance of the clamping parts 31 being too long.

[0051] Optionally, the clamping assembly 3 includes two first driving members 32 disposed on the first frame 1 and the second frame 2. The clamping member 31 is strip-shaped and extends along the stacking direction of the tray. The first driving members 32 are connected to the clamping member 31 in a transmission manner. The two first driving members 32 are used to drive the two clamping members 31 to move closer to each other or further away from each other.

[0052] In this embodiment, the first driving member 32 can be an electric push rod, which can directly drive the clamping member 31 to extend and retract in the space 100. At the same time, the clamping member 31 is strip-shaped and extends along the stacking direction of the pallets, ensuring that the pallets stacked in the row can be effectively pushed and prevented from shifting.

[0053] Specifically, when a whole row of pallets is placed into space 100, the two first driving members 32 respectively drive the clamping members 31 to move closer to each other, thereby contacting the side of the pallet to push the pallet and align the protruding side walls of the pallet. After the above actions are completed, the two first driving members 32 respectively drive the clamping members 31 to move away from each other, thereby maintaining the stable stacking of the whole row of pallets.

[0054] Please see the appendix Figure 3 and attached Figure 4 Optionally, the clamping assembly 3 further includes two guide members 33 extending along the relative movement direction of the clamping member 31, with the two clamping members 31 slidably connected to the two guide members 33 respectively.

[0055] Specifically, the two first driving members 32 are respectively disposed inside the opposing plates of the first frame 1 and the second frame 2. The guide member 33 is a cylindrical rod. In this embodiment, two guide members 33 are disposed on each side. The guide member 33 passes through the opposing wall surfaces of the first frame 1 and the second frame 2. At the same time, the guide member 33 is slidably connected to the clamping member 31.

[0056] In this embodiment, by providing multiple guide members 33, support can be provided for the clamping member 31, while ensuring the stability of the movement.

[0057] Optionally, the first frame 1 is provided with a first connecting part 11, and the second frame 2 is provided with a second connecting part 21, wherein the first connecting part 11 and the second connecting part 21 are slidably connected. One of the first connecting part 11 and the second connecting part 21 is provided with a sliding groove 211, and the other of the first connecting part 11 and the second connecting part 21 is slidably disposed in the sliding groove 211.

[0058] Specifically, a slide groove 211 is provided on the second connecting part 21, and the first connecting part 11 is inserted into the slide groove 211 and can slide along the slide groove 211. The slide groove 211 can provide guidance for the sliding of the first connecting part 11, thereby ensuring that the first frame 1 moves stably relative to the second frame 2.

[0059] Optionally, a second driving member 41 is provided on one of the first frame 1 and the second frame 2. The second driving member 41 is connected to the first screw 42 in a transmission connection. The first screw 42 is threadedly connected to the other of the first frame 1 and the second frame 2. The second driving member 41 is used to drive the first screw 42 to rotate so that the first frame 1 and the second frame 2 are relatively closer or relatively farther apart.

[0060] Specifically, a second driving member 41 is fixed on the outward-facing wall of the second connecting part 21. The second driving member 41 can be a rotary motor, with its output end connected to the first screw 42. A connecting block 111 is protruding on the outward-facing wall of the first connecting part 11. The connecting block 111 can be integrally formed on the first frame 1, and the first screw 42 is screwed into the connecting block 111. When the second driving member 41 rotates clockwise, it drives the first screw 42 to rotate clockwise, thereby causing the first frame 1 to gradually move away from the second frame 2. When the second driving member 41 rotates counterclockwise, it drives the first screw 42 to rotate counterclockwise, thereby causing the first frame 1 to gradually move closer to the second frame 2.

[0061] Optionally, guide wheels 5 are respectively provided on the inner walls of the first frame 1 and the second frame 2, and the tray can be rotated and guided into the space 100 by the guide wheels 5.

[0062] Specifically, guide wheels 5 are protruding on the inner walls of the first frame 1 and the second frame 2. When a forklift pushes a pallet into the space 100, the guide wheels 5 will contact the pallet first, thus guiding multiple pallets into pre-positioning, making it easier for the pallet and the forklift to enter the space 100. During the process of pushing the pallet in, the forklift can stop and activate the first drive component 32 to push the clamping component 31 out, allowing the clamping component 31 to move along the direction of the guide component 33. This allows multiple pallets to be neatly arranged by the pushing of the clamping component 31, so that when the pallets are stacked later, they can be stacked neatly. The neat arrangement of the pallets reduces the chance of the pallets tipping over, making the pallets more stable when stacking.

[0063] In this embodiment, the guide wheel 5 helps the pallet enter the space 100 more smoothly, ensuring smooth operation and improving loading efficiency; in addition, it can further prevent the pallet from being squeezed and damaged due to misalignment with the space 100.

[0064] Please see the appendix Figure 5 and attached Figure 6 Optionally, the pallet sorting machine also includes two lifting components 6, which are respectively mounted on the first frame 1 and the second frame 2. Each lifting component 6 includes a third drive member 61 and a platform 62 that is pulsatorically connected to the third drive member 61. The third drive member 61 is used to drive the platform 62 to move along the pallet stacking direction. The platform 62 is provided with rollers 63 that can be supported on the ground. The rollers 63 can roll along the relative movement direction of the first frame 1 and the second frame 2.

[0065] Specifically, the third drive unit 61 can be an electric actuator to move the platform 62 along the stacking direction of the pallets. Rollers 63 are respectively provided on the underside of the two platforms 62. When the first frame 1 and the second frame 2 are aligned, the third drive unit 61 can first move the rollers 63 to press them against the ground, thus supporting the first frame 1 and the second frame 2. Then, by activating the second drive unit 41, the first frame 1 moves relative to the second frame 2. After the position is adjusted, the third drive unit 61 can move the platform 62 upwards to retract the rollers 63 into the first frame 1 and the second frame 2.

[0066] In this embodiment, platform 62 is used to move the tray.

[0067] In this embodiment, by setting rollers 63, the first frame 1 can be moved relative to the second frame 2 in a rolling manner, which is more conducive to the movement of the first frame 1 relative to the second frame 2. The movement and adjustment can be carried out without the need for lifting tools, which improves the convenience of moving the first frame 1 relative to the second frame 2.

[0068] Optionally, multiple support feet 9 are also provided at the bottom of the first frame 1 and the second frame 2. After the positions of the first frame 1 and the second frame 2 are adjusted, the rollers 63 are retracted into the first frame 1 and the second frame 2. The multiple support feet 9 support the ground to achieve stable support for the first frame 1 and the second frame 2.

[0069] Optionally, the lifting assembly 6 includes a second screw 66 extending along the pallet stacking direction, a third drive member 61 being drivenly connected to the second screw 66, and a platform 62 being drivenly connected to the second screw 66.

[0070] Specifically, the second screw 66 extends along the stacking direction of the pallets. The third drive unit 61 is a rotary motor, and its drive end is connected to a worm gear 64, which can drive the worm gear 64 to rotate. A worm wheel 65 is fixed to the end of the second screw 66. The worm gear 64 and worm wheel 65 mesh and transmit power, thereby enabling the third drive unit 61 to drive the second screw 66 to rotate. The second screw 66 is then further threadedly connected to the platform 62, thus achieving the lifting and lowering of the platform 62. It should be noted that the two lifting components 6 move synchronously, ensuring that the two platforms 62 maintain the same height during movement. Simultaneously, the self-locking property of the worm gear 64 and worm wheel 65 prevents the pallets from shifting during vertical movement, improving the stability of the platform 62 during ascent and descent and ensuring safety.

[0071] Optionally, the pallet counter also includes two oppositely arranged tray insertion assemblies 7. The tray insertion assembly 7 includes a fourth drive member 71 and a claw 72. The fourth drive member 71 can drive the claw 72 to extend and retract within the space 100. The claw 72 is used to insert and pick up the tray.

[0072] Specifically, the fourth driving component 71 is an electric actuator, and the driving end of the electric actuator is connected to a rack 73. The rack 73 engages with the meshing part 721 of the inserter 72. When the fourth driving component 71 pushes the rack 73 to move, the rack 73 will drive the meshing part 721 to rotate, thereby allowing the claw head 722 to extend out of the space 100 and be inserted into the corresponding tray, so that it can move flexibly in the vertical direction under the action of the lifting component 6 and the platform 62.

[0073] Furthermore, the insert plate assembly 7 is located on platform 62.

[0074] In this embodiment, the fourth drive member 71, rack 73 and claw 72 are all connected to the platform 62. The rack 73 is slidably mounted on the platform 62, and the claw 72 is rotatably connected to the platform 62. Since the claw 72 needs to extend and retract in the space 100, a strip hole for the claw 72 to pass through is provided on the first frame 1 and the second frame 2, and the strip hole extends along the moving direction of the claw 72, which is vertical in this embodiment.

[0075] When the inserter 72 is damaged, broken, or worn, it can be removed from the lifting platform 62, thus facilitating the maintenance and replacement of the consumable inserter 72.

[0076] In this embodiment, the pallet coder also includes a control terminal 10, which is signal-connected to the first drive unit 32, the second drive unit 41, the third drive unit 61 and the fourth drive unit 71, and is used to control the opening and closing of the corresponding drive units.

[0077] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
