Description

Technical Field

[0001] This invention relates to the field of logistics pallet technology, specifically to a logistics pallet positioning device. Background Technology

[0002] Logistics pallets are horizontal platform devices used for the unitization, stacking, handling, and transportation of goods and products as unit loads. They play a significant role in modern logistics. Used in conjunction with forklifts, they enable the unitization, standardization, and normalization of goods packaging, protecting goods and facilitating logistics and commerce. Existing logistics pallets, including those for cargo transportation, suffer from the following problems: they cannot locate goods during transport, leading to loss and damage during transit, and they cannot guarantee the stability of goods, affecting the safety and stability of transportation.

[0003] According to the description in the patent publication on the Internet of Things (authorization announcement number: CN114229177A), the logistics transportation pallet includes "base, pallet platform, guide telescopic rod", etc., to place goods.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This logistics transportation pallet uses a base, pallet platform, and guide telescopic rods to place goods. During use, the pallet's elastic support components can absorb shock waves and reduce the vibration of the goods, but it can only play a buffering role and cannot fix the goods. This leads to the loss and damage of goods during transportation and cannot guarantee the stability of the goods, affecting the safety and stability of transportation. Therefore, this pallet needs to be improved. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. This logistics pallet positioning device, through its positioning components, enables the placement of goods on a pallet body for transportation. When goods are placed on a placement platform, the weight of the goods causes the platform to move downwards. This movement of the platform drives a rack and pinion mechanism, which in turn rotates a gear. This rotation, in turn, rotates a support column, clamping plate, and limiting plate, positioning the support column and clamping plate on either side of the goods. When the clamping plate contacts the goods, the first and second springs deform, thus securing the goods. Simultaneously, the device can adjust the positioning mechanism based on the weight of the goods. The position of the clamping plate is automatically adjusted according to the amount of goods, ensuring the clamping plate is stable and securing the goods. Based on the stacking height of the goods, the rectangular frame can be pulled, moving the limiting plate and causing the telescopic rod and third spring to deform. This further positions the top of the goods via the limiting plate, ensuring stability on the top of the placement platform. The support column and rotating block are secured with bolts, facilitating installation and removal of the support column. During the movement of the placement platform, the pressing block moves, creating a linkage with the limiting components, which in turn limits the position of the limiting plate via the insert rod.

[0021] 2. This logistics pallet positioning device, through its limit components, enables the following operation: When goods are placed on the pallet body for transportation, the goods are placed on the top of the placement platform. Under the pressure of the weight, the placement platform moves downwards. Simultaneously, the support columns and clamps rotate under the action of gears and racks, securing the goods to the left and right sides. The placement platform drives the pressing block to move, which in turn drives the inclined block. The inclined block then moves the connecting rod, moving plate, and insert rod, allowing the insert rod to insert into the limit plate. When the placement platform moves downwards and contacts the top of the pallet body, and the support columns and clamps rotate under the action of gears and racks, the insert rod simultaneously inserts into the limit plate, thus limiting the position of the limit plate. The limiting plate limits the rotation rod and gears, preventing gear rotation caused by external factors during cargo positioning under the action of the support column and clamping plate, thus affecting the stability of the support column and clamping plate. It can also achieve a linkage effect with the positioning component. The limiting ensures that the support column and clamping plate are in a stable state. When the placement platform moves, it will drive the squeezing block to move. When it moves to a certain position, it will squeeze the squeezing block, causing the squeezing block to drive the connecting rod, moving plate and insert rod to move, and causing the fourth spring to deform. When the support column and clamping plate have completed positioning the left and right sides of the cargo, the insert rod can be inserted into the limiting plate at the same time to limit the gears. When the squeezing block releases the squeezing of the inclined block, the fourth spring resets, which can reset the moving plate, insert rod, inclined block and connecting rod to start the next limiting operation.

[0022] 3. This logistics pallet positioning device, through its rotating mechanism, enables the pallet body and the fixed goods to rotate around the fixed plate when goods are placed on the pallet body for transportation. The worm gear, worm wheel, and rotating plate drive the L-shaped seat and casters to rotate. This rotation makes it easier for forklifts or other loading / unloading equipment to grasp the goods, especially when space is limited or goods need to be moved in different directions. Furthermore, in confined environments where goods stacked on the pallet body need to be inspected for damage, rotation allows workers to visually inspect the goods, avoiding the complex process of moving back and forth in limited spaces. This improves inspection efficiency and comprehensiveness. In warehouses and transportation vehicles, rotating pallet bodies help to utilize space more effectively, especially when compact stacking or rapid changes in goods orientation are required, thus improving usability.

[0023] 4. This logistics pallet positioning device, through its buffer mechanism, allows for the placement of goods on the pallet body during transport. The weight of the goods presses down on the placement platform and the support frame, causing the connecting shaft to change angle within the support frame and the moving seat. Furthermore, the sliding rod compresses the fifth spring, which in turn provides cushioning to the moving seat. This cushioning helps to protect the goods during placement, preventing damage to the bottom of the goods. During transport, especially on bumpy roads, the fifth spring absorbs some of the impact, reducing damage caused by vibration or collision and further ensuring the stability of the goods during transport.

[0050] Furthermore, a movable groove is provided around the fixed disk 33, and the rotating disk 34 is rotatably connected to the movable groove, so that the rotating disk 34 can drive the L-shaped seat 39 and the universal wheel 391 to rotate under the action of the movable groove. Example 4

[0051] See Figure 1-13Based on Examples 1, 2, and 3, the buffer mechanism 4 further includes a slide rod 41, which is fixedly connected to the inner side of the tray body 1. A movable seat 42 is slidably connected to the outer side of the slide rod 41. The front side of the movable seat 42 is slidably connected to the inside of the tray body 1. A fifth spring 43 is sleeved around the slide rod 41. The left side of the fifth spring 43 is fixedly connected to the right side of the movable seat 42. The right side of the fifth spring 43 is fixedly connected to the inside of the tray body 1. A first round rod 44 is fixedly connected inside the movable seat 42. A connecting shaft 45 is rotatably connected to the outer side of the first round rod 44. A second round rod 46 is rotatably connected inside the connecting shaft 45. A load-bearing frame 47 is fixedly connected to the outer side of the second round rod 46. The load-bearing frame 47 is fixedly connected to the bottom of the placement platform 211.

[0052] Furthermore, a movable groove is provided inside the tray body 1, and the front side of the movable seat 42 is slidably connected to the movable groove, so that the movable seat 42 can slide more stably around the slide rod 41 under the action of the movable groove.

[0053] In actual operation, when this device is used, and goods need to be placed on the pallet body 1 for transportation, the goods are first stacked on top of the placement platform 211. Under the weight of the goods, the placement platform 211 can move downwards. When the placement platform 211 moves, it will squeeze the support frame 47, causing the support frame 47 to move downwards. This also causes the connecting shaft 45 to change angle around the first round rod 44 and the second round rod 46, and drives the moving seat 42 to slide around the slide rod 41, squeezing the fifth spring 43. The elasticity of the fifth spring 43 can then buffer the moving seat 42. This buffering can cushion the goods when they are placed, preventing damage to the bottom goods during the lowering process. This creates compression, thus protecting the goods. As the placement platform 211 moves downwards, it drives the rack 213 via the connecting block 212, causing the rack 213 to rotate the gear 218. Under the action of the gear 218, the rotating rod 219 rotates the rotating block 2191, support column 214, clamping plate 2197, and limiting plate 2198, positioning the support column 214 and clamping plate 2197 on the left and right sides of the goods. When the clamping plate 2197 contacts the goods, the first spring 2194 and the second spring 2196 deform, thus securing the goods under the action of the clamping plate 2197. Simultaneously, the position of the clamping plate 2197 can be automatically adjusted according to the amount of goods, ensuring the clamping plate 2197... While maintaining a stable state, the goods are secured. Simultaneously, based on the stacking height of the goods, the rectangular frame 2199 is pulled, causing the limiting plate 2198 to move. This causes the telescopic rod 21992 and the third spring 21993 to deform, bringing the inner side of the limiting plate 2198 into contact with the top of the goods. This further positions the top of the goods via the limiting plate 2198, ensuring the goods are stable on the top of the placement platform 211. As the placement platform 211 moves, when its bottom contacts the top of the pallet body 1 and the top of the top plate 216, the support column 214, clamping plate 2197, and limiting plate 2198 rotate, completing the positioning of the goods. When the placement platform 211 moves, the... When the pressure block 221 moves to a certain position, it will press the inclined block 222, causing the pressure block 221 to drive the connecting rod 223, the moving plate 226, and the insert rod 227 to move, and causing the fourth spring 225 to deform. When the support column 214 and the clamping plate 2197 have completed positioning the left and right sides of the goods, the insert rod 227 can be simultaneously inserted into the limiting plate 2192 to limit the gear 218. This prevents the gear 218 from rotating due to external factors when positioning the goods under the action of the support column 214 and the clamping plate 2197, thus affecting the stability of the support column 214 and the clamping plate 2197. When it is necessary to inspect the goods or for other work that requires rotating the pallet body 1 and the goods,First, the second cylinder 32 drives the fixed plate 33 to move, which in turn moves the rotating plate 34 and the caster 391, bringing the caster 391 into contact with the ground. Once contact is established, the servo motor 37 drives the worm wheel 36, which meshes with the worm gear 38 on the right side, to rotate. The worm wheel 36 then drives the rotating plate 34 to rotate around the fixed plate 33, which in turn drives the caster 391 to rotate. Under the action of the caster 391, the pallet body 1 and the goods rotate for inspection and other tasks. During the lifting and lowering process of the caster 391, it is only necessary to keep the caster 391 in contact with the ground, slightly lifting the bottom of the pallet body 1 off the ground to ensure stability during rotation. This allows for the inspection of the goods. During the inspection process, when the transportation is complete and the goods need to be unloaded, the first cylinder 215 drives the top plate 216 to rise and fall, causing the top plate 216 to press against the placement platform 211. This causes the placement platform 211 to move the pressing block 221, releasing the pressing block 221 from the inclined block 222. When the pressing block 221 releases its pressure on the inclined block 222, the fourth spring 225 resets, allowing the moving plate 226, insert rod 227, inclined block 222, and connecting rod 223 to reset, releasing the limit on the limiting plate 2192. This allows the rack 213 to drive the gear 218 to rotate again, moving the support column 214, clamping plate 2197, and limiting plate 2198 away from the left and right sides of the goods, releasing the positioning of the goods, and allowing them to be unloaded.
