Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and particularly relates to an adaptive pallet stacking positioning device. Background Art

[0002] Pallet stacking refers to the operation of stacking multiple pallets together to maximize storage space and improve material efficiency. Pallet stacking is usually used in the warehousing and material industries, which can effectively utilize vertical space. When stacking pallets, a pallet stacking positioning device is needed to position them to ensure neat stacking.

[0003] During the use of the existing adaptive pallet stacking positioning device, although a portal-shaped structure is formed by the support frame and the support plate to position the pallets during stacking, since the support frame and the support plate are fixed and non-adjustable, the positioning device can only be used to position pallets of a single size, resulting in low practicability and flexibility. Therefore, a new type of adaptive pallet stacking positioning device is urgently needed to solve these problems. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] As Figures 1-4As shown in the figure, an adaptive pallet stacking and positioning device in this embodiment includes an adjusting plate 1. A sliding groove 2 is centrally formed on one side wall of the adjusting plate 1, and fixing holes 3 are equidistantly arranged in the sliding groove 2. Two groups of support frames 4 are symmetrically arranged on one side wall of the adjusting plate 1. At the position of the sliding groove 2, two groups of support frames 4 are fixed with connecting blocks 5. The cooperation between the sliding groove 2 and the connecting blocks 5 can make it more convenient for the support frames 4 to slide on the adjusting plate 1, facilitating the adjustment of the width of the positioning device according to the size of the pallet body 15. The support frames 4 can fix the connecting blocks 5 more firmly. A fixing bolt 6 is connected to the connecting blocks 5. Adjusting members 7 are installed on both side walls of the two groups of support frames 4. The adjusting member 7 is composed of an adjusting block 8 and an adjusting cover 9. The fixing bolt 6 can make it more convenient for the support frames 4 to be fixed on the adjusting plate 1 through the connecting blocks 5, facilitating the staff to flexibly adjust the size of the positioning device. The support frames 4 can fix the adjusting blocks 8 and the adjusting covers 9 more firmly. On one side wall of each group of support frames 4, two groups of strengthening blocks 10 are fixed. On each group of strengthening blocks 10, a rotating rod 11 is installed. A connecting plate 12 is arranged on the rotating rod 11. A positioning plate 13 is fixed at the top of the connecting plate 12. The strengthening blocks 10 can improve the strength of the bottom support frames 4. The strengthening blocks 10 can make it more convenient for the rotating rod 11 to rotate on the support frames 4. When the pallet body 15 is stacked and lifted, the positioning plate 13 can slightly rotate on the support frames 4 under the cooperation of the connecting plate 12 and the rotating rod 11 by the force of the pallet body 15 being lifted.

[0028] As Figures 1-4 shown in the figure, in this embodiment, a spring 14 is installed between the positioning plate 13 and the top of the support frame 4. A pallet body 15 is connected to the positioning plate 13. At the bottom end of each group of support frames 4, a support base 16 is fixed. The spring 14 can make it more convenient to connect the positioning plate 13 and the support frame 4. The spring 14 is convenient to pull the lifted positioning plate 13 back onto the support frame 4. The support frame 4 can better support the positioning plate 13 to prevent the positioning plate 13 from descending due to the weight of the pallet body 15. The sliding groove 2 is formed on one side wall of the adjusting plate 1. The support frame 4 and the connecting block 5 are welded. Each group of support frames 4 has two. Both the positioning plate 13 and the support frame 4 are bolted to the spring 14. The support frame 4 and the support base 16 are bolted. The support frame 4 can fix the support base 16 more stably. The support base 16 can improve the stability of the positioning device. The fixing bolt 6 passes through the connecting block 5 and is threadedly connected to the fixing hole 3. Both the adjusting block 8 and the adjusting cover 9 are welded to the support frame 4. Adjusting holes are equidistantly arranged on the adjusting block 8. An adjusting bolt is arranged on the adjusting cover 9 and is threadedly connected to the adjusting hole. The cooperation between the adjusting hole and the adjusting bolt can better fix the adjusting block 8 in the adjusting cover 9. The adjusting member 7 can conveniently connect the two support frames 4 stably together. The support frame 4 and the strengthening block 10 are welded. Each group of strengthening blocks 10 is composed of a large one and a small one. The rotating rod 11 is rotatably connected to the strengthening block 10. Both the rotating rod 11 and the positioning plate 13 are bolted to the connecting plate 12.

[0029] In the present invention, the support frame 4 is welded to the reinforcing block 10.

[0030] In the present invention, a scale mark is provided on the adjusting plate 1. The scale mark corresponds to the length direction of the sliding groove 2, and the scale accuracy is 1 mm.

[0031] In the present invention, a pressure sensor is installed on the positioning plate 13. The pressure sensor is electrically connected to an external control device. When the tray body 15 is placed on the positioning plate 13, the pressure sensor monitors the weight of the tray in real time and transmits the data to the external control device. The external control device determines whether the tray stacking is stable according to the pressure data. If the pressure is abnormal, an alarm is issued.

[0032] The specific implementation process of this embodiment is as follows: During use, first, the staff uses a forklift to move the tray body 15 to be stacked between the two support frames 4, and raises the tray body 15 through the forklift. The upward force generated by raising the tray body 15 can cause the positioning plate 13 to rotate the rotating rod 11 on the reinforcing block 10 through the connecting plate 12. When the positioning plate 13 is located in the slot provided on the side wall of the tray body 15, the spring 14 can automatically reset the raised positioning plate 13. The top of the support frame 4 can support the positioning plate 13 to prevent the tray body 15 stacked on the positioning plate 13 from falling. By repeating this process, the stacking of the tray body 15 can be achieved. By providing the sliding groove 2 on one side wall of the adjusting plate 1, it is convenient for the two support frames 4 to move in the sliding groove 2 through the connecting block 5. Turn the fixing bolt 6 so that it passes through the connecting block 5 and is threadedly connected to the fixing hole 3, and the two support frames 4 after adjusting the position can be fixed on the adjusting plate 1, which is convenient for adjusting the width that the positioning device can position. By providing the adjusting member 7, the cooperation between the adjusting block 8 and the adjusting cover 9 is convenient for extending the length of the two support frames 4, and can be adjusted according to the size of the tray body 15 during use, improving the practicability and flexibility of the positioning device.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
