Description

Technical Field

[0001] This utility model relates to the field of four-sided shaping devices, specifically a four-sided shaping device for pallet stacking. Background Technology

[0002] In the logistics and warehousing sector, pallets serve as the core carrier for goods transport and turnover, and their stacking regularity directly affects the smoothness of subsequent automated warehousing processes. Currently, pallet stacking operations in the industry largely rely on manual labor. Due to factors such as the skill level of operators and the intensity of their work, manual pallet stacking is prone to problems such as uneven placement of goods, resulting in an uneven overall shape of the pallet stack.

[0003] To ensure that pallet stacks are neatly entered into the warehousing process, they can be shaped using a shaping device. However, existing pallet stack shaping devices require rotating the pallet stack 90° after clamping and shaping the left and right sides of the pallet stack before clamping and shaping the front and rear sides. This results in low shaping efficiency and the need to add a rotating mechanism to drive the pallet stack to rotate, leading to high shaping costs.

[0004] The research objective of this utility model is to design a four-sided shaping device for pallet stacking that addresses the problems existing in the prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a four-sided shaping device for pallet stacking, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is: A four-sided shaping device for pallet stacking includes: The frame is equipped with a feeding area for inputting pallet stacks; A transverse shaping mechanism is provided on the frame and includes a plurality of shaping rollers and a transverse driving device. The plurality of shaping rollers are all arranged to rotate laterally and are respectively located on both sides of the transverse side of the feeding area. The transverse driving device is used to drive the shaping roller on at least one side to transversely shape. A longitudinal shaping mechanism is provided on the frame and includes a plurality of shaping parts and a longitudinal movement drive device. The plurality of shaping parts are driven to move laterally by the transverse movement drive device and are respectively corresponding to the longitudinal sides of the feeding area. The longitudinal movement drive device is used to drive the shaping parts on at least one side to move longitudinally for shaping. When the shaping rollers have completed transverse shaping and the shaping parts have completed longitudinal shaping, the transverse sides of the pallet stack are limited by the transverse rolling of the plurality of shaping rollers and move linearly along the longitudinal direction.

[0007] Furthermore, the frame includes a first frame and a second frame that are laterally spaced and form the feeding area between them. The lateral movement drive device includes a lateral movement frame that is laterally movably disposed on the second frame and a drive assembly disposed on the second frame for driving the lateral movement frame to move laterally. The plurality of shaping rollers include a plurality of fixed rollers disposed on the first frame and a plurality of movable rollers disposed on the lateral movement frame. The plurality of shaping parts are longitudinally movably disposed on the lateral movement frame. The longitudinal movement drive device is disposed on the lateral movement frame and is used to drive the shaping parts on both sides to be squeezed and shaped towards each other.

[0008] Furthermore, the shaping roller extends vertically, and the number of fixed rollers and movable rollers is two, which are longitudinally spaced apart. The driving assembly includes a conveyor chain that extends laterally between the two movable rollers and is sleeved on the sprocket, and a first motor for driving the sprocket to rotate. The longitudinal sides of the transverse frame are laterally slidably connected to the second frame through transverse pulleys and transverse grooves, and the middle side is connected to the upper side of the conveyor chain.

[0009] Furthermore, the number of shaping components is set to two, and they are located on one side of the feed area together with the movable roller. The movable roller is mounted on the side of the transverse frame near the feed area and forms a drive area with the transverse frame. The transverse frame is provided with two vertically distributed longitudinal slide rails located in the drive area. The opposing sides of the two shaping components are respectively provided with drive plates located in the drive area and distributed vertically. The two shaping components are respectively longitudinally slidably connected to the two longitudinal slide rails by longitudinal sliding sliders. The two drive plates are respectively longitudinally slidably connected to the two longitudinal slide rails by longitudinal sliding sliders and are provided with vertically symmetrical racks on the opposing sides. The longitudinal drive device includes a gear rotatably mounted on the transverse frame and meshing with the two racks on the upper and lower sides respectively, and a second motor for driving the gear to rotate.

[0010] Furthermore, the two shaping components extend vertically and their ends protrude laterally from the side of the movable roller near the feeding area.

[0011] Furthermore, the two shaping parts are designed as longitudinally symmetrical and oppositely shaped groove plates. The groove depth of the shaping parts gradually increases towards the transverse moving frame. Several reinforcing ribs are vertically fixed on opposite sides of the two shaping parts and are arranged laterally. The area of ​​the reinforcing ribs is adapted to the cross-section of the groove depth of the shaping parts.

[0012] Therefore, the beneficial effects of this utility model are: 1. By configuring several shaping rollers and several shaping components that can move laterally and longitudinally, when the shaping rollers complete the lateral shaping and the shaping components move laterally to the longitudinal sides of the pallet stack for longitudinal shaping, the lateral sides of the pallet stack are limited by the lateral rolling of the shaping rollers and move linearly along the longitudinal direction. Thus, by configuring several shaping rollers, not only can the pallet stack be laterally shaped, but the pallet stack can also be limited during the longitudinal shaping of the shaping components, ensuring the effectiveness of both lateral and longitudinal shaping and guaranteeing the shaping effect. Furthermore, when the lateral drive device drives at least one side of the shaping roller to press and shape towards the inside of the feeding area, it simultaneously drives the shaping components to move inward into the feeding area and correspond to the longitudinal sides of the pallet stack. This allows the shaping components to be laterally moved to the outside of the feeding area during longitudinal feeding of the pallet stack, avoiding obstruction of the longitudinal feeding of the pallet stack. The lateral shaping of the shaping rollers, driven by the lateral drive device, drives the shaping components to move inward for shaping, eliminating the need for an additional lateral drive device to drive the lateral movement of the shaping components, thus reducing drive costs.

[0013] 2. By designing fixed and movable rollers, the lateral movement drive device only needs to drive the movable roller on one side for lateral compression and shaping during transverse forming. This allows the lateral and longitudinal movement drive devices to be concentrated on the second frame on one side of the transverse direction, with only the tall and narrow first frame and forming roller on the other side. This improves the structural compactness of the drive device, significantly reduces the space occupied by the four-sided forming device, avoids spatial conflicts with parallel conveyor lines in the warehousing system, and significantly enhances the adaptability of the four-sided forming device in dense warehousing and conveying systems. Furthermore, traditional double-sided drive equipment has a complex structure and many parts, resulting in high initial installation costs and requiring separate maintenance of both drive systems, which is time-consuming and labor-intensive. The single-sided power design simplifies the overall structure, reduces the number of drive components, lowers equipment manufacturing costs and failure rates, and only requires operation on one side of the power system during maintenance, significantly shortening maintenance time, reducing the operating costs of the warehousing system, and improving the practicality of the four-sided forming device.

[0014] 3. By distributing the conveyor chain between the two movable rollers, the space between the two movable rollers is fully utilized, further improving the structural compactness of the four-sided shaping device.

[0015] 4. By meshing the symmetrically distributed racks and gears, the gears can precisely and synchronously drive the two drive plates to move towards or away from each other when they rotate, thereby precisely and synchronously driving the two forming parts to move towards or away from each other. This avoids movement deviations between the two forming parts, improves the longitudinal forming effect, and, through the setting of the drive area, can improve the structural compactness while avoiding interference between the two forming parts moving towards each other and the movable roller.

[0016] 5. By protruding the shaping components, it is ensured that while the transverse frame drives the movable roller to move laterally inward for shaping, it can also move the two shaping components laterally inward to both sides of the pallet stack, thereby ensuring that the two shaping components can perform longitudinal shaping on the pallet stack. By setting the two shaping components as grooved plates with opposite groove openings, not only can the overall center of gravity of the shaping components be lowered, reducing the driving load of the first drive device, but also several reinforcing ribs with gradually increasing width towards the transverse frame can be fixedly set in the groove by utilizing the change in groove depth, thereby improving the overall structural strength of the shaping components.

[0022] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-5 A four-sided shaping device for pallet stacking, comprising: The frame 1 is provided with a feeding area 11 for inputting pallet stacks. Specifically, the feeding area 11 is used for longitudinally inputting pallet stacks. The transverse shaping mechanism 2 (not shown in the figure) is located on the frame 1 and includes a plurality of shaping rollers 21 and a transverse driving device 22. The plurality of shaping rollers 21 are all arranged to rotate laterally and are respectively located on both sides of the feed area 11. The transverse driving device 22 is used to drive at least one side of the shaping roller 21 to transversely shape. The longitudinal shaping mechanism 3 (not shown in the figure) is located on the frame 1 and includes a plurality of shaping parts 31 and a longitudinal movement drive device 32. The plurality of shaping parts 31 are driven to move laterally by the transverse movement drive device 22 and are respectively corresponding to the longitudinal sides of the feeding area 11. The longitudinal movement drive device 32 is used to drive the shaping parts 31 on at least one side to move longitudinally and shape them.

[0023] The above structure, through the arrangement of several shaping rollers 21 and several shaping components 31 that can move laterally and longitudinally, ensures that when the shaping rollers 21 have completed the lateral shaping and the shaping components 31 have moved laterally to the longitudinal sides of the pallet stack and moved longitudinally for shaping, the lateral sides of the pallet stack are limited by the lateral rolling of the several shaping rollers 21 and move linearly along the longitudinal direction. Thus, by setting up several shaping rollers 21, not only can the pallet stack be shaped laterally, but the pallet stack can also be limited during the longitudinal shaping of the shaping component 31, ensuring the effectiveness of both lateral and longitudinal shaping and ensuring the shaping effect. Furthermore, when the lateral movement drive device 22 drives at least one side of the shaping roller 21 to press and shape towards the inside of the feeding area 11, it simultaneously drives the shaping component 31 to move inward into the feeding area 11 and correspond to the longitudinal sides of the pallet stack. This allows the shaping component 31 to be laterally moved to the outside of the feeding area 11 during the longitudinal feeding of the pallet stack, so as to avoid obstructing the longitudinal feeding of the pallet stack. The lateral movement drive device 22 drives the shaping roller 21 to move the shaping component 31 inward for shaping, eliminating the need to install an additional lateral movement drive device 22 to drive the lateral movement of the shaping component 31, thus reducing the driving cost.

[0024] To improve the overall structural compactness of the four-sided shaping device, the frame 1 includes a first frame 12 and a second frame 13 that are laterally spaced and form the feeding area 11 between them. The transverse drive device 22 includes a transverse frame 221 that is laterally movable on the second frame 13 and a drive assembly that is mounted on the second frame 13 and used to drive the transverse frame 221 to move laterally. The plurality of shaping rollers 21 include a plurality of fixed rollers 211 mounted on the first frame 12 and a plurality of movable rollers 212 mounted on the transverse frame 221. The plurality of shaping parts 31 are longitudinally movable on the transverse frame 221. The longitudinal drive device 32 is mounted on the transverse frame 221 and used to drive the shaping parts 31 on both sides to be squeezed and shaped towards each other. The aforementioned structure, through the design of fixed roller 211 and movable roller 212, allows the lateral movement drive device 22 to drive only one side of the movable roller 212 for lateral compression and shaping during lateral forming. This enables the lateral movement drive device 22 and longitudinal movement drive device 32 to be concentrated on the second frame 13 on one side of the lateral movement, while only the tall and narrow first frame 12 and shaping roller 21 are set on the other side of the lateral movement. This improves the structural compactness of the drive device, significantly reduces the space occupied by the four-sided shaping device, avoids spatial conflicts with parallel conveyor lines in the warehousing system, and significantly improves the adaptability of the four-sided shaping device in dense warehousing and conveying systems. Furthermore, traditional double-sided drive equipment has a complex structure and a large number of parts, resulting in high initial installation costs and the need for separate maintenance of both drive systems, which is time-consuming and labor-intensive. The single-sided power design not only simplifies the overall structure but also reduces the number of drive components, lowering equipment manufacturing costs and failure rates. Maintenance only requires operation on one side of the power system, significantly shortening maintenance time, reducing the operating costs of the warehousing system, and improving the practicality of the four-sided shaping device.

[0025] To further improve the structural compactness of the four-sided shaping device, the shaping roller 21 extends vertically, and the number of fixed rollers 211 and movable rollers 212 is two each, spaced longitudinally apart. The driving assembly includes a conveyor chain 222 extending laterally between the two movable rollers 212 and sleeved on a sprocket 224, and a first motor 223 for driving the sprocket 224 to rotate. The longitudinal sides of the transverse frame 221 are laterally slidably connected to the second frame 13 via transverse pulleys 23 and transverse grooves 131, and the middle side is connected to the upper side of the conveyor chain 222. This structure, by distributing the conveyor chain 222 between the two movable rollers 212, fully utilizes the space between the two movable rollers 212, further improving the structural compactness of the four-sided shaping device.

[0026] To improve the longitudinal shaping effect, the number of shaping components 31 is set to two and is located on the transverse side of the feeding area 11 together with the movable roller 212. The movable roller 212 is mounted on the side of the transverse frame 221 near the feeding area 11 and forms a driving area 24 between the transverse frame 221 and the transverse frame 221. The transverse frame 221 is provided with two longitudinal sliding rails 25 distributed vertically and located in the driving area 24. The opposing sides of the two shaping components 31 are respectively provided with driving plates 33 located in the driving area 24 and distributed vertically. The two shaping components 31 are respectively longitudinally slidably connected to the two longitudinal sliding rails 25 by longitudinal sliding sliders. The two driving plates 33 are respectively longitudinally slidably connected to the two longitudinal sliding rails 25 by longitudinal sliding sliders and are provided with symmetrical racks 331 on the opposing sides. The longitudinal driving device 32 includes a gear 321 rotatably mounted on the transverse frame 221 and meshing with the two racks 331 on the upper and lower sides respectively, and a second motor 322 for driving the gear 321 to rotate. The above structure uses symmetrically distributed racks 331 and gears 321 to mesh, so that when the gears 321 rotate, they can precisely and synchronously drive the two drive plates 33 to move towards each other or in opposite directions. This, in turn, precisely and synchronously drives the two shaping parts 31 to move towards each other or in opposite directions, avoiding movement deviations between the two shaping parts 31 and improving the longitudinal shaping effect. Furthermore, the setting of the drive area 24 can improve the structural compactness while avoiding interference between the two shaping parts 31 moving towards each other and the movable roller 212.

[0027] To ensure that the two shaping components 31 correspond to the longitudinal sides of the pallet stack after moving inward, the two shaping components 31 are arranged vertically and horizontally with their ends protruding laterally from the side of the movable roller 212 near the feeding area 11. Thus, by protruding the shaping components 31, it is ensured that while the transverse frame 221 moves the movable roller 212 laterally inward for shaping, it can also move the two shaping components 31 laterally inward to the longitudinal sides of the pallet stack, thereby ensuring that the two shaping components 31 can perform longitudinal shaping on the pallet stack.

[0028] To improve the structural strength of the shaping components 31, the two shaping components 31 are designed as longitudinally symmetrical, grooved plates with opposite groove openings. The groove depth of the shaping components 31 gradually increases towards the transverse frame 221. Several vertically spaced, transversely arranged reinforcing ribs 311 are vertically fixed on opposite sides of the two shaping components 31, with the area of ​​the reinforcing ribs 311 matching the cross-sectional area of ​​the groove depth of the shaping component 31. By designing the two shaping components 31 as grooved plates with opposite groove openings, not only can the overall center of gravity of the shaping components 31 be lowered, reducing the driving burden on the first driving device, but the variation in groove depth also allows for the fixed installation of several reinforcing ribs 311 with gradually increasing width towards the transverse frame 221, thereby improving the overall structural strength of the shaping components 31.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
