Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment, specifically to a piano key type pallet positioning device and a shelf pallet positioning system. Background Technology

[0002] In today's era of booming efficient logistics and intelligent warehousing, automated storage and retrieval systems (AS / RS) pallets, as an indispensable key element, are playing an increasingly important role. AS / RS pallets are specifically designed for automated storage and retrieval systems. Compared to traditional pallets, they have higher requirements in terms of dimensional accuracy, load-bearing capacity, and stability. Precise dimensions ensure smooth adaptation between automated handling equipment and racking, preventing jamming or deviation, thereby guaranteeing the continuity and efficiency of the entire warehousing operation process.

[0003] Currently, pallets placed on automated warehouse shelves are often moved or fallen due to external forces (such as earthquakes), causing unnecessary losses. Utility Model Content

[0004] The purpose of this utility model is to provide a piano key type pallet positioning device and a shelf pallet positioning system to solve the technical problem that existing pallets placed on automated warehouse shelves often move or fall due to external forces (such as earthquakes).

[0005] In view of the above objectives, in the first aspect, this application provides a piano key type tray positioning device, including a connecting plate, a first support plate, a second support plate and a baffle;

[0006] The connecting plate is arranged laterally, and one end of it is used to connect to the crossbeam of the shelf. When the connecting plate is subjected to downward pressure, it can bend downward to deform and can self-reset after the pressure is removed.

[0007] The first support plate is arranged vertically, and its bottom is connected to the other end of the connecting plate.

[0008] The second support plate is arranged laterally, and its two ends are connected between the first support plate and the baffle.

[0009] The baffle is arranged vertically, and the top of the baffle is higher than the bottom surface of the tray, for preventing horizontal movement of the tray.

[0010] Furthermore, the connecting plate is provided with mounting holes for bolting to the crossbeams of the shelf.

[0011] Furthermore, the connecting plate, the first support plate, the second support plate, and the baffle are integrally bent from stainless steel plates.

[0012] Furthermore, the thickness of the connecting plate, the first support plate, the second support plate, and the baffle is 1-3mm.

[0013] Furthermore, the distance between the top surface of the second support plate and the top surface of the crossbeam of the shelf is 5-10mm.

[0014] Furthermore, the width of the second support plate is smaller than the width of the connecting plate.

[0015] Furthermore, the height of the baffle is 5-15mm.

[0016] Secondly, this application provides a rack pallet positioning system, including several crossbeams for placing pallets, and the aforementioned piano key type pallet positioning device.

[0017] Among the crossbeams around the pallet, at least one crossbeam is connected to at least one of the piano key type pallet positioning devices, which limit the position of at least one side of the pallet.

[0018] Furthermore, in the crossbeams located on the front and rear sides of the tray, each crossbeam is connected to at least one of the piano key type tray positioning devices.

[0019] Furthermore, in the crossbeams located on the left and right sides of the tray, each crossbeam is connected to at least one of the piano key type tray positioning devices.

[0020] By adopting the above technical solution, the piano key type tray positioning device provided in this application has the following technical advantages compared with the prior art:

[0021] In this design, one end of the connecting plate is used to connect to the crossbeam of the shelf. When the connecting plate is subjected to downward pressure, it can bend downward and deform, and it can self-reset after the pressure is removed. The bottom of the first support plate is connected to the other end of the connecting plate, and the two ends of the second support plate are connected between the first support plate and the baffle. The baffle is arranged vertically, and the top of the baffle is higher than the bottom surface of the pallet, which is used to prevent the pallet from moving horizontally. This product can be installed on the crossbeams around the pallet (front, back, left, and right directions) to prevent the pallet from moving horizontally. Alternatively, it can be pressed down and rendered ineffective. Because the connecting plate is elastic, the top of the second support plate will be automatically pressed down by the pallet without affecting the normal operation of the pallet. It is particularly suitable for pallets of different specifications. Attached Figure Description

[0033] Example 1

[0034] Figure 1 The schematic diagram illustrates the structure of the piano key type tray positioning device provided in this embodiment. Figure 2 This diagram illustrates the structure of the piano key type tray positioning device under pressure.

[0035] like Figure 1 and Figure 2 As shown, the piano key type tray positioning device provided in this embodiment includes a connecting plate 100, a first support plate 200, a second support plate 300, and a baffle 400.

[0036] Among them, the connecting plate 100 is arranged in the transverse direction, and one end of it is used to connect to the crossbeam 1 of the shelf. However, when the connecting plate 100 is subjected to downward pressure, it can bend downward and deform. After the pressure is removed, it can self-reset.

[0037] The first support plate 200 is arranged vertically, and the bottom of the first support plate 200 is connected to the other end of the connecting plate 100.

[0038] The second support plate 300 is arranged in a transverse direction, that is, the second support plate 300 is parallel to the connecting plate 100, and the two ends of the second support plate 300 are connected between the first support plate 200 and the baffle 400.

[0039] The baffle 400 is arranged vertically, and the top of the baffle 400 is higher than the bottom surface of the tray 2, in order to prevent the horizontal movement of the tray 2.

[0040] In application, the connecting plate 100 can be horizontally installed on the crossbeams 1 around the pallet 2 (in the four directions of front, back, left, and right) and the baffle 400 can block the horizontal movement of the pallet 2; it can also be pressed down and rendered ineffective. Because the connecting plate 100 is elastic, the top of the second support plate 300 will be automatically pressed down by the pallet 2 without affecting the normal operation of the pallet. It is particularly suitable for pallets of different specifications.

[0041] As a preferred embodiment, the connecting plate 100 is provided with mounting holes for bolting to the crossbeam 1 of the shelf. Specifically, it can be assembled with the mounting holes pre-set at the bottom of the crossbeam 1 by bolts.

[0042] As a preferred embodiment, the connecting plate 100, the first support plate 200, the second support plate 300 and the baffle 400 are integrally bent from stainless steel plates.

[0043] In this embodiment, the plates are straight. In actual processing and application, each plate can be bent multiple times to increase strength. In addition, it should be noted that the overall shape of the piano key type pallet positioning device in this embodiment can also be modified in other similar ways, including bending one or more of the connecting plate 100, the first support plate 200, the second support plate 300 and the baffle 400 once or multiple times to increase the overall strength, changing the geometric dimensions of the steel plate (such as changing the distance between the top surface of the baffle 400 and the second support plate 300 relative to the bottom surface of the pallet 2, or adopting an irregular shape, or adopting a folded edge, rolled edge, etc.), changing the installation method (such as installing on a special support beam), changing the connection method (such as changing the number of bolts), etc. At the same time, the protection of this solution is not affected by changes in the material and thickness of the steel plate.

[0044] In addition, the preferred thickness of the connecting plate 100, the first support plate 200, the second support plate 300 and the baffle 400 is 1-3mm; it can also be adjusted according to actual needs.

[0045] Please refer to Figure 5 The distance L between the top surface of the second support plate 300 and the top surface of the crossbeam 1 of the shelf is 5-10mm, and the height of the baffle 400 is 5-15mm.

[0046] In this embodiment, since the top of the baffle 400 is connected to the second support plate 300, the baffle 400 can block the side of the pallet 2, thereby preventing the horizontal movement of the pallet 2. Of course, the second support plate 300 can also be pressed down by the large pallet 2 and lose its function. Since the steel plate is elastic, the second support plate 300 will be automatically pressed down by the pallet 2 without affecting the normal operation of the pallet. This is particularly suitable for pallets of different sizes.

[0047] As a preferred embodiment, the width of the second support plate 300 is smaller than the width of the connecting plate 100, which facilitates the installation of the connecting plate 100 on the crossbeam 1, and the width of the crossbeam 1 will not cause interference.

[0048] Example 2

[0049] Figure 3 This is a front view of the pallet positioning system provided in this embodiment (the crossbeams on both sides of the pallet are omitted). Figure 4 yes Figure 3 Side view, Figure 5 yes Figure 4 Enlarged view of point A in the middle;

[0050] Please combine Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a rack pallet positioning system, including several beams 1 for placing pallets, and the piano key type pallet positioning device 3 in the above embodiment 1.

[0051] Among them, at least one of the crossbeams 1 around the pallet is connected to at least one piano key type pallet positioning device 3, which limits at least one side of the pallet 2.

[0052] Please refer to Figures 3-5 In a preferred embodiment, each of the crossbeams 1 located on the front and rear sides of the pallet 2 is connected to at least one piano-key type pallet positioning device 3. For example, if three piano-key type pallet positioning devices 3 are configured on each crossbeam 1, the pallet positioning devices are fixed to the corresponding crossbeams 1 at preset intervals, thereby limiting the front and rear sides of the pallet. Of course, the number of piano-key type pallet positioning devices on each crossbeam 1 can be increased or decreased depending on the actual usage.

[0053] In a preferred embodiment, each of the crossbeams 1 located on the left and right sides of the pallet 2 is connected to at least one piano-key type pallet positioning device 3. Taking three piano-key type pallet positioning devices on each crossbeam 1 as an example, the pallet positioning devices are fixed to the corresponding crossbeams 1 at preset intervals, thereby limiting the left and right sides of the pallet. Of course, the number of piano-key type pallet positioning devices 3 on each crossbeam 1 can be increased or decreased depending on the actual usage. It should be noted that since the installation method of the piano-key type pallet positioning devices on the left and right crossbeams 1 of the pallet 2 is the same as that on the front and rear crossbeams 1, the installation diagram of the left and right crossbeams 1 and the piano-key type pallet positioning devices 3 is omitted in this embodiment.

[0054] By installing the piano-key type pallet positioning device 3 in the front, back, left, and right directions of the pallet, the movement of the pallet can be effectively restricted. When the pallet 2 has only one size, the piano-key type pallet positioning device 3 can be used to move the pallet in all four horizontal directions. When the pallet 2 has multiple sizes, by setting multiple sets of piano-key type pallet positioning devices 3, it can adapt to various pallet sizes. This device is more commonly used for situations where pallets have multiple sizes.

[0055] Figure 6 This diagram illustrates the assembly of a pallet positioning system using large-sized pallets (the crossbeams on both sides of the pallet are omitted).

[0056] Reference Figure 6 When using a large-sized pallet 2, when pallet 2 presses down on the upper surface of the second support plate 300 (generally required to be within the range of 5~10kg), the second support plate 300 will sink under pressure due to the external force, thus not affecting the normal storage of pallet 2. When the external force is released, the second support plate 300 will return to its initial state due to elasticity. The steel plate material should have high elasticity to ensure automatic recovery after deformation, preventing permanent deformation, and be able to withstand long-term and repeated pressure. General high-elasticity steel is sufficient. The thickness of the steel plate is very important; it must have a certain horizontal resistance capacity, and its size should be designed according to the operating conditions, such as seismic loads. If one set is insufficient when the external force is too large, multiple sets can be designed. It is necessary to avoid steel plates that are too thin, resulting in insufficient resistance, and steel plates that are too thick, causing permanent plastic deformation or failing to meet requirements. The pressure applied should not exceed 25% of the empty pallet's own weight to ensure that the empty pallet is not affected during storage.

[0057] In addition, it should be noted that when the shelving is not designed with beams for installing piano-key pallet positioning devices, or when the shelving is of another type that makes installation impossible, beams should be considered. Beams can be made of rectangular tubing or angle steel, requiring a certain degree of rigidity but not necessarily high load-bearing capacity.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
