Utility Model Content

[0003] Traditional pallet frames typically consist of multiple bases sequentially inserted into a rectangular frame. This makes assembly and disassembly complex and lacks flexibility. Furthermore, customizing a pallet to a specific size requires redesigning the entire frame, increasing production and maintenance costs. Therefore, a more convenient and cost-effective pallet design is needed that can adapt to different needs without having to re-manufacture the entire pallet frame.

[0004] Based on this, the present invention proposes a novel pallet design. This design utilizes truncated side frames and L-shaped corner pieces for assembly, enabling rapid adjustment of pallet size to meet varying needs and reducing manufacturing and maintenance costs. Furthermore, friction strips at the bottom of the rectangular frame enhance wear resistance, while slots in the center of the side frames secure the pallet with screws and nuts, further enhancing the pallet's stability. By providing clearance openings, the stopper can pass through any of the clearance openings, effectively preventing the pallet from moving, enhancing control precision, and ensuring efficient, flexible, and stable operation of the pallet on automated conveyor lines.

[0006] Furthermore, a friction strip is provided in the middle area of ​​the bottom of the side frame, and the cross-sectional shape of the friction strip is the same as the bottom cross-sectional shape of the two ends of the L-shaped corner piece. The side frame and the friction strip are arranged in parallel and plug-fitted.

[0007] Furthermore, the bottom lengths of both ends of the L-shaped corner piece are longer than the top length of the L-shaped corner piece.

[0008] Furthermore, when the L-shaped corner piece is docked with the side frame, the top of the side frame and the top of the L-shaped corner piece together form a receiving groove for plugging with the support plate.

[0009] Furthermore, a placement groove for placing nuts is provided in the middle of the side frame, and the side frame and the supporting plate are fixed by screws and nuts.

[0010] Furthermore, a sensor sheet is provided on the side of the rectangular frame.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0026] Example 1: Figures 1 to 8As shown, this embodiment provides a pallet for a logistics conveyor line, comprising a rectangular frame and a pallet 4, wherein the pallet 4 is located within the rectangular frame. The rectangular frame is composed of a rectangular first frame composed of four side frames 1 and an L-shaped corner piece 3 connecting two adjacent side frames 1. The top of the side frame 1 is provided with a slot 11 for plugging into the pallet 4, the notch of the slot 11 faces the inside of the rectangular frame and the slot 11 is provided along the outer edge of the rectangular frame; the cross-section of the bottom of the side frame 1 is formed on both sides with an L-shaped groove 12, and the bottom cross-section of the two ends of the L-shaped corner piece 3 is concave 34, which is plugged into the cross-section of the bottom of the side frame 1. The bottoms of the two ends of the L-shaped corner piece 3 are longer than the top of the L-shaped corner piece 3. In other words, a step 31 is formed between the two ends of the bottom of the L-shaped corner piece 3 and the top of the L-shaped corner piece 3. When the L-shaped corner piece 3 is docked with the side frame 1, the end of the L-shaped groove 12 is inserted into the concave shape 34, and the end of the placement groove 13 rests on the step 31. The top of the side frame 1 and the top of the L-shaped corner piece 3 together form a receiving groove 32 for plugging into the pallet 4. The side frame 1 and the friction strip 2 are both die-extruded parts and can be cut into any length as needed to adapt to different pallet requirements.

[0027] A sensing sheet 5 is provided on the side of the rectangular frame, and the sensing sheet 5 serves to complete the position detection and control of the pallet. The upper edge of the sensing sheet 5 is lower than the upper surface of the rectangular frame, which can prevent the sensing sheet 5 from contacting and rubbing with the conveyor line, thereby ensuring the accuracy of the sensing detection.

[0028] A plurality of positioning pin sleeves 6 are provided at the bottom of the support plate 4, which facilitates the replacement and maintenance of the positioning pin sleeves 6. For workstations with lifting and rotation, it is convenient to arrange the positions of the positioning pins, making the lifting and rotation structure simpler. The pallet is driven to rotate by inserting the lifting and rotating positioning pins into the positioning pin sleeves 6, making the pallet rotation smoother.

[0029] On this basis, a friction strip 2 is provided in the middle area of ​​the bottom of the side frame 1. The cross-sectional shape of the friction strip 2 is the same as the bottom cross-sectional shape of the two ends of the L-shaped corner piece 3. The side frame 1 and the friction strip 2 are arranged parallel and plug-fit together. The friction strip 2 is made of PE plastic to improve the wear resistance of the bottom of the rectangular frame in contact with the conveyor line.

[0030] In order to enhance the stability of the support plate 4 and the rectangular frame, a placement groove 13 for placing the nut 8 is provided in the middle of the side frame 1. After the screw 7 passes through the support plate 4 and the side frame 1 in sequence, the screw 7 is connected and matched with the nut 8 to fix the support plate 4 and the side frame 1.

[0031] Furthermore, if Figure 1 and Figure 2As shown, each of the four side frames 1 has a clearance opening 33 at the bottom, and the clearance openings 33 are staggered relative to each other on the rectangular frame. The purpose of providing the clearance openings 33 and each clearance opening 33 is to facilitate the passage of the stopper through any of the clearance openings 33 during the movement of the pallet on the conveyor line. After the stopper passes through the side frame 1 where the clearance opening 33 is located, the stopper prevents the side frame 1 parallel to the side frame 1 passing through from passing through.

[0032] In this embodiment, the rectangular frame is composed of a side frame 1 and an L-shaped corner piece 3. The top of the side frame 1 is provided with a slot 11 that plugs into the pallet 4, and the bottom is provided with an L-shaped groove 12 that plugs into the L-shaped corner piece 3. This allows the pallet to be cut into the side frame 1 as needed to accommodate different size requirements, improving flexibility and applicability. The combined design of the rectangular frame and the pallet 4 solves the problem of the existing technology requiring customized production for special pallet sizes, significantly reducing costs. By using the cuttable side frame 1 and L-shaped corner piece 3 to achieve assembly, the pallet size can be quickly adjusted according to different needs, reducing manufacturing and maintenance costs. In addition, the friction strip 2 at the bottom of the rectangular frame enhances wear resistance, while the placement groove 13 in the middle of the side frame 1 secures the pallet 4 with screws 7 and nuts 8, further enhancing the stability of the pallet. By providing a clearance opening 33, the stopper can pass through any of the clearance openings 33, effectively preventing the movement of the pallet, enhancing control accuracy, and achieving efficient, flexible, and stable operation of the pallet on the automated conveyor line.
