Description

Technical Field

[0001] The utility model relates to the technical field and relates to a tray automatic positioning device. Background Art

[0002] Pallets are often used in the process of loading logistics goods. The pallet mainly plays the role of supporting goods and facilitating the loading and unloading of goods by trailers or forklifts. The function of the pallet is relatively single, and the structure of the pallet is also relatively simple. Generally, it is a support plate with slots and is mostly an integrated structure, mainly injection molded parts. The manufacturing process is simple and the manufacturing cost is low.

[0003] In the actual use process of the pallet, in order to prevent the goods from sliding on the pallet, anti-slip pads are often added to the pallet to increase the friction between the pallet and the goods. The existing methods of adding anti-slip pads are mainly divided into two types: one is to manually embed the anti-slip pad into the pallet; the other is to use a manipulator to embed the anti-slip pad into the pallet. For the above two schemes, manual installation is time-consuming and laborious, which greatly affects the production efficiency. And the method of using a manipulator for installation requires positioning the pallet before installation. The existing positioning methods are usually manual positioning or using a positioning table for positioning. The manual positioning method still affects the production efficiency of the pallet, and the positioning table can usually only position a single pallet. When the size of the pallet changes, the positioning platform needs to be replaced. In this case, the manufacturing cost of the new platform and the inventory cost of the old platform both greatly increase the production cost. Summary of the Utility Model

[0004] The utility model provides a tray automatic positioning device to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A tray automatic positioning device includes a positioning table. A load-bearing column is arranged on the positioning table. A bearing plane for carrying the tray is arranged on the load-bearing column. Two groups of limiting mechanisms and a pushing mechanism are arranged on the positioning table. Each group of the limiting mechanism and the pushing mechanism are correspondingly arranged at both ends of the positioning table. The limiting mechanism includes a limiting base and a limiting plate slidably arranged on the limiting base. A locking structure is arranged between the limiting plate and the limiting base. The pushing mechanism includes a pushing cylinder fixedly arranged on the positioning table and a pushing plate arranged at the end of the piston rod of the pushing cylinder.

[0006] Further improvement, the limiting base includes a limiting seat and a sliding rod. The limiting plate is slidably arranged on the sliding rod and a locking bolt is arranged at the lower end. The locking bolt is threadedly connected with the limiting plate and the lower end abuts against the upper surface of the sliding rod.

[0007] For further improvement, a guiding mechanism is arranged outside the pushing cylinder. The guiding mechanism includes a guiding seat and guiding rods arranged between the guiding seats. A connecting block is arranged at the lower end of the pushing plate. The middle part of the connecting block is fixedly arranged at the end of the piston rod of the pushing cylinder, and the two sides are slidably sleeved on the guiding rods.

[0008] For further improvement, an avoidance groove is arranged on the bearing plane, and the avoidance groove is arranged corresponding to the limiting mechanism and the pushing mechanism.

[0009] For further improvement, multiple groups of load-bearing columns are provided.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. During the actual use of the utility model, the manipulator places the tray that needs to be assembled with the anti-slip pad on the bearing plane. By applying forces to both ends of the tray through two groups of pushing mechanisms, the tray is moved on the bearing plane towards the limiting mechanism to achieve positioning, which is convenient for the later direct assembly of the anti-slip pad by the manipulator. The positioning mechanism replaces manual positioning of the tray, improving the automation degree of the equipment and the production efficiency.

[0022] Embodiment 1

[0023] An automatic pallet positioning device includes a positioning table 1. A load-bearing column 11 is arranged on the positioning table 1. A bearing plane 2 for carrying the pallet is arranged on the load-bearing column 11. Two groups of limiting mechanisms 3 and a pushing mechanism 4 are arranged on the positioning table 1. Each group of the limiting mechanisms 3 and the pushing mechanism 4 are correspondingly arranged at both ends of the positioning table 1. The limiting mechanism 3 includes a limiting base 31 and a limiting plate 32 slidably arranged on the limiting base 31. A locking structure is arranged between the limiting plate 32 and the limiting base 31. The pushing mechanism 4 includes a pushing cylinder 41 fixedly arranged on the positioning table 1 and a pushing plate 42 arranged at the end of the piston rod of the pushing cylinder 41.

[0024] As Figures 1 to 5 shown, during the actual use of the present utility model, the manipulator places the pallet to be assembled with an anti-slip pad on the bearing plane 2. By applying forces to both ends of the pallet through the two groups of pushing mechanisms 4, the pallet moves on the bearing plane 2 towards the limiting mechanism 3 to achieve positioning, which is convenient for the subsequent direct assembly of the anti-slip pad by the manipulator. The positioning mechanism replaces manual positioning of the pallet, improving the automation degree of the equipment and the production efficiency.

[0025] The limiting plate 32 for positioning can be adjusted in position on the limiting base 31 according to the actual size of the pallet to meet the positioning requirements of pallets of different sizes, expanding the applicability of the equipment and saving production costs.

[0026] As a further preferred embodiment, the limiting base 31 includes a limiting seat 311 and a sliding rod 312. The limiting plate 32 is slidably arranged on the sliding rod 312, and a locking bolt 321 is arranged at the lower end thereof. The locking bolt 321 is threadedly connected to the limiting plate 32, and the lower end abuts against the upper surface of the sliding rod 312.

[0027] Specifically, as Figure 3 shown, the limiting plate 32 is slidably arranged on the sliding rod 312. When positioning pallets of different sizes is required, only by loosening the locking bolt 321 can the locking between the limiting plate 32 and the sliding rod 312 be released. The structure is simple and the operation is convenient.

[0028] As a further preferred embodiment, a guiding mechanism 5 is arranged outside the pushing air cylinder 41. The guiding mechanism 5 includes a guiding seat 51 and guiding rods 52 arranged between the guiding seats 51. A connecting block 421 is arranged at the lower end of the pushing plate 42. The middle part of the connecting block 421 is fixedly arranged at the end of the piston rod of the pushing air cylinder 41, and both sides are slidably sleeved on the guiding rods 52.

[0029] Specifically, as Figure 4 shown, the piston rod of the pushing air cylinder 41 is guided by the guiding mechanism 5, so as to prevent the pushing plate 42 from shifting during the movement process, and further improve the positioning accuracy.

[0030] As a further preferred embodiment, an avoidance groove 21 is arranged on the bearing plane 2. The avoidance groove 21 is arranged corresponding to the limiting mechanism 3 and the pushing mechanism 4, so as to prevent the limiting mechanism 3 and the pushing mechanism 4 from interfering with the bearing plane 2.

[0031] As a further preferred embodiment, multiple groups of load-bearing columns 11 are provided.

[0032] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
