Description

Technical Field

[0001] This application belongs to the field of casting production, and in particular relates to a casting turnover pallet suitable for automated production lines. Background Technology

[0002] In the process of transforming the foundry industry into a smart factory, the introduction of intelligent conveying systems has reduced the production cycle to ≤90s / piece. However, traditional casting turnover pallets have exposed the following defects in conveying on the conveyor line: Traditional pallets adopt a flat or frame structure, and the number of stacking layers is generally ≤3 layers. If the stacking is high, the overall transportation is unstable. Under the combined load of the casting weight and the vibration of the conveyor belt, traditional pallets are prone to deformation, which leads to the positioning of the castings being misaligned and the entire pallet becoming unusable after deformation. While simply increasing the thickness of the pallet can solve the deformation problem, it also increases the energy consumption of the conveying mechanism. Therefore, it is evident that the existing technology needs further improvement and enhancement. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: A casting turnover pallet suitable for automated production lines includes a bottom pallet and an upper pallet. A support structure is provided between the bottom pallet and the upper pallet. The bottom pallet has slot notches at its four corners. The upper pallet has four positioning blocks around its perimeter corresponding to the slot notches. Vertical guard plates are provided between adjacent positioning blocks. When the pallets are stacked, the positioning blocks are positioned into the slot notches to achieve stacking stability. In a preferred embodiment, the bottom support plate includes a rectangular closed bottom frame plate with bottom stiffeners arranged longitudinally and laterally inside the frame plate; a rectangular closed middle frame plate is provided below the upper support plate with middle stiffeners arranged longitudinally and laterally inside the frame plate; the bottom frame plate and the middle frame plate correspond to each other and the bottom stiffeners and the middle stiffeners correspond to each other; and a support structure is provided between the bottom frame plate and the middle frame plate and between the bottom stiffeners and the middle stiffeners.

[0005] In a preferred embodiment, the support structure includes a first hollow square tube and a second hollow square tube, wherein the first hollow square tube is disposed between the middle frame plate and the bottom frame plate, and the second hollow square tube is disposed between the middle stiffening plate and the bottom stiffening plate.

[0006] In a preferred implementation, the thickness of the first hollow square tube and the second hollow square tube are adapted to the length of the positioning block, the width of the first hollow square tube is adapted to the width of the middle frame plate / bottom frame plate, and the width of the second hollow square tube is adapted to the width of the middle stiffening plate / bottom stiffening plate.

[0007] In a preferred embodiment, the first hollow square tube is provided with a groove, and the groove is provided with a mounting hole. The sign is connected to the first hollow square tube by rivets passing through the mounting hole.

[0008] In a preferred implementation, the upper tray has multiple through holes, which are spaced equally to form a matrix array.

[0009] In a preferred implementation, a hanger is provided at the center of the adjacent positioning block, and the hanger includes a connecting column and a lifting ring on the connecting column.

[0010] In the preferred implementation, the positioning block and the hanging connecting column are both connected to the middle frame plate, and the upper support plate is provided with the corresponding positioning block and connecting column clearance groove.

[0015] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0016] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; 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. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0018] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0019] The present invention will now be described with reference to the accompanying drawings.

[0020] The specific solution adopted is as follows: like Figure 1-4 As shown, this utility model provides a casting turnover pallet suitable for automated production lines, including a bottom pallet 1 and an upper pallet 2. A support structure 4 is provided between the bottom pallet 1 and the upper pallet 2. The bottom pallet 1 has slot notches 10 at its four corners. The upper pallet 2 has four positioning blocks 3 around its perimeter corresponding to the slot notches 10. Vertical guard plates 5 are provided between adjacent positioning blocks 3. When the pallet is stacked, the positioning blocks 3 are positioned into the slot notches 10. The structure of the positioning blocks 3 and the slot notches 10 makes the stacking and disassembly of the pallet faster and more accurate, and can be seamlessly connected with automated equipment. Through the cooperation and limiting of the positioning blocks 3 and the slot notches 10, as well as the limiting effect of the vertical guard plates 5, the stability of stacking can be significantly improved. During transportation, the castings can be placed stably on the pallet, reducing casting damage and production line failures caused by unstable stacking.

[0021] As a preferred embodiment of this application, see [link to application]. Figure 3 The bottom support plate 1 includes a rectangular closed bottom frame plate 11, with bottom stiffeners 12 arranged longitudinally and laterally inside the frame plate; a rectangular closed middle frame plate 6 is provided below the upper support plate 2, with middle stiffeners 7 arranged longitudinally and laterally inside the frame plate; the bottom frame plate 11 and the middle frame plate 6 correspond to each other, and the bottom stiffeners 12 and the middle stiffeners 7 correspond to each other; the support structure 4 is provided between the bottom frame plate 11 and the middle frame plate 6 and between the bottom stiffeners 12 and the middle stiffeners 7.

[0022] Both the bottom frame plate 11 and the middle frame plate 6 are rectangular closed structures, providing a stable basic support frame for the entire pallet. The rectangular closed structure has high resistance to deformation, capable of withstanding forces and torques from all directions, effectively preventing the pallet from twisting or deforming during stacking and transportation. The bottom stiffening plates 12 and middle stiffening plates 7, arranged longitudinally and laterally, further enhance the structural strength of the pallet. The stiffening plates can distribute the forces acting on the pallet over a larger area, reducing local stress concentration. When castings are placed on the pallet, the stiffening plates can bear part of the weight of the castings and transfer it to the frame plates, thereby improving the pallet's load-bearing capacity. The frame plate and stiffening plate structure avoids the use of large areas of solid sheet metal. While a single sheet of metal has high strength, it is also heavy, increasing the energy consumption of the conveyor mechanism. The combined design of the frame plates and stiffening plates reduces material usage while ensuring pallet strength, thus reducing the pallet's weight. The frame plates and corresponding stiffening plates can be connected by welding.

[0023] The pallet can stably and safely stack at least four identical pallets vertically under full load, and the stacked structure is stable with no deformation, cracking or tipping tendency.

[0024] See Figure 1-3 The supporting structure 4 includes a first hollow square tube 40 and a second hollow square tube 41. The first hollow square tube 40 is located between the middle frame plate 6 and the bottom frame plate 11, and the second hollow square tube 41 is located between the middle stiffening plate 7 and the bottom stiffening plate 12.

[0025] The first hollow square tube 40 between the middle frame plate 6 and the bottom frame plate 11, and the second hollow square tube 41 between the middle stiffening plate 7 and the bottom stiffening plate 12, form a three-dimensional support network. When the upper pallet 2 holds the casting, the weight of the casting is transferred to the middle frame plate 6 and the middle stiffening plate 7 through the upper pallet 2, and then the first and second hollow square tubes 41 evenly distribute the load to the bottom frame plate 11 and the bottom stiffening plate 12. This even load distribution avoids local stress concentration and prevents the pallet from deforming or being damaged due to excessive local stress. The hollow square tube design allows for a significant reduction in material usage while ensuring load-bearing capacity. Compared to solid support columns 30, the hollow square tube, through its reasonable hollow structure design, eliminates unnecessary material while meeting strength requirements, reducing pallet manufacturing costs and energy consumption during transportation.

[0026] Furthermore, the thickness of the first hollow square tube 40 and the second hollow square tube 41 are adapted to the length of the positioning block 3, so that the depth of the notch formed matches the positioning block 3. The width of the first hollow square tube 40 is adapted to the width of the middle frame plate 6 / bottom frame plate 11, and the width of the second hollow square tube 41 is adapted to the width of the middle stiffening plate 7 / bottom stiffening plate 12. By designing the size of the square tube, unnecessary material usage is reduced. The adaptable design can minimize material usage and reduce the weight of the pallet while ensuring load-bearing capacity.

[0027] See Figure 1 and Figure 2 The first hollow square tube 40 has a recess 400 with mounting holes. The identification plate is connected to the first hollow square tube 40 via rivets 401 passing through the mounting holes. The recess 400 on the first hollow square tube 40 for mounting the identification plate makes full use of the structural space of the square tube without increasing the overall size of the pallet. This compact design allows the pallet to better adapt to the storage requirements of automated equipment and warehouses within limited space. The identification plate can carry a wealth of information, such as the pallet number, batch number, purpose, and type of casting it supports. In automated production lines or warehouse management, workers can quickly distinguish different pallets by checking the identification plates.

[0028] See Figure 4 The upper support plate 2 has multiple through holes 20, which are evenly spaced to form a matrix array. When castings produced in high-temperature environments are placed on the support plate with through holes 20, air can circulate around the castings through the through holes 20, carrying away heat, reducing the casting temperature, and preventing overheating from affecting the quality of the castings. The matrix arrangement of the through holes 20 makes the heat dissipation effect on the support plate better and the stress distribution more uniform.

[0029] See Figure 1 and Figure 3 The center of the adjacent positioning block 3 is also provided with a hanging 8. The hanging 8 includes a connecting column 80 and a lifting ring 81 on the connecting column 80. The positioning block 3 and the connecting column 80 of the hanging 8 are both welded to the middle frame plate 6. The upper support plate 2 is provided with a relief groove 21 corresponding to the positioning block 3 and the connecting column 80. The upper support plate 2 is movably placed on the upper side of the middle frame plate 6 and the middle stiffening plate 7.

[0030] The connecting column 80 and positioning block 3 of the hanging 8 are both connected to the middle frame plate 6. When lifting the moving pallet and castings, the lifting equipment applies tension through the lifting ring 81. This tension acts directly on the middle frame plate 6 instead of the upper pallet 2. Since the middle frame plate 6 is one of the important load-bearing components in the pallet structure, it can more effectively bear and transmit the lifting force. In this way, the upper pallet 2, which is in direct contact with the castings, is not subjected to tension and is not easily damaged or deformed. The upper pallet 2 is movably installed on the middle frame plate 6 and the middle stiffening plate 7. When the upper pallet 2 is worn or damaged due to long-term use or needs to be replaced according to the requirements of different castings, the upper pallet 2 can be easily removed for replacement.

[0031] In a preferred embodiment of this application, the positioning block 3 includes a support column 30 and a guide block 31 at the end of the support column 30. The guide block 31 is narrower at the top and wider at the bottom. This narrower-at-the-top structure makes it easier for the guide block 31 to be inserted into the slot notch 10. Operators or automated equipment do not need to precisely align the positioning slot; they only need to bring the guide block 31 approximately close to the positioning area. The narrower part can easily enter the entrance of the slot notch 10, and then the positioning is completed naturally as the pallet moves. This greatly reduces the difficulty of the positioning operation and improves stacking efficiency.

[0032] In a preferred embodiment of this application, the bottom support plate 1, the upper support plate 2, the support structure 4, and the positioning block 3 are made of carbon structural steel.

[0033] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
