Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a storage pallet. Background Art

[0002] In the modern warehousing and logistics system, storage pallets are the basic tools for cargo storage and handling, and their performance and efficiency directly affect the operation quality of the entire logistics chain. Traditional storage pallets are mostly fixed in design, that is, once the height, shape and size of the pallet are determined, it is difficult to adjust according to actual needs, which to a certain extent limits its applicability in different storage environments and handling equipment.

[0003] In order to overcome the limitations of traditional pallets, some height-adjustable storage pallets have gradually appeared on the market. These pallets usually achieve height adjustment through mechanical structures or pneumatic devices. Although they improve flexibility to a certain extent, they often have problems such as complex structures, high maintenance costs, and insufficient adjustment accuracy. In addition, these pallets still require manual participation in the handling process of goods, and cannot achieve automated movement of goods, thus affecting handling efficiency and accuracy.

[0004] On the other hand, with the continuous development of automation technology, more and more automation equipment has been introduced into the field of warehousing and logistics, such as automated handling robots, unmanned forklifts, etc. These devices have put forward higher requirements for storage pallets, not only requiring pallets to be able to adapt to different storage heights, but also requiring pallets to be able to seamlessly connect with automation equipment to achieve automated handling of goods. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, an object of the present invention is to provide a storage pallet having the function of carrying and pushing away goods.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a storage pallet, including a base plate, a pallet panel and a height adjustment mechanism, wherein the pallet panel is arranged above the base plate as a direct bearing surface for the goods; the base plate is the bottom supporting structure of the pallet panel.

[0007] The height adjustment mechanism is arranged between the base plate and the tray panel to adjust the distance between the two.

[0008] Among them, a plurality of rotating wheels are rotatably installed on the surface of the substrate, the rotating directions of the plurality of rotating wheels are the same, and the axes of the plurality of rotating wheels are parallel to the surface of the substrate, and an arc groove adapted to the rotating wheel is opened inside the tray panel.

[0009] When the pallet panel is located away from the base plate, the bearing surface of the pallet panel is higher than the highest point of the upper end of the rotating wheel, and part of the rotating wheel is located inside the arc groove; when the pallet panel is located close to the base plate, the bearing surface of the pallet panel is lower than the highest point of the upper end of the rotating wheel, and the rotating wheel is a supporting component for carrying goods.

[0010] Preferably, a plurality of supports that rotate in the horizontal direction are installed on the surface of the substrate, the rotating wheel is rotatably installed inside the supports, a plurality of circular holes that match the rotating wheel one by one are opened inside the tray panel, a turntable is rotatably installed in the circular hole, and the arc groove is opened inside the turntable.

[0011] Preferably, a plurality of the supports are arranged inside the substrate along the X-axis direction and the Y-axis direction, a gear ring is fixed on each of the supports, any two adjacent gear rings in the X-axis direction are meshed with a gear, and in the Y-axis direction, at least one row of gear rings are meshed with gears, the gears are rotatably installed inside the substrate, and a motor for driving any gear to rotate is installed inside the substrate.

[0012] Preferably, a motor for driving the rotating wheel to rotate is installed inside each of the supports.

[0013] Preferably, the tray panel comprises a transverse plate and a skirt plate, wherein the skirt plate is connected to the periphery of the transverse plate, and the tray panel is sleeved on the base plate through the skirt plate.

[0014] Preferably, the height adjustment mechanism includes an oil chamber arranged inside the base plate, a slide plate is slidably installed in the oil chamber, a sealing ring is provided on the surface of the slide plate in contact with the inner wall of the oil chamber, a connecting shaft is fixed to the bottom of the cross plate, the lower end of the connecting shaft passes through the shell of the base plate and is connected to the slide plate, an oil inlet pipe and an oil outlet pipe are connected to the oil chamber, and valves are installed on the oil inlet pipe and the oil outlet pipe.

[0016] Preferably, there are multiple coupling shafts, and the multiple coupling shafts are inserted into the gaps inside the substrate.

[0017] The beneficial effects of the present invention are: The wheels of the present invention are rotatably mounted inside the support, and can collectively act on the goods on the pallet panel, generating thrust in the same direction to push the goods away from the storage pallet. This design realizes the automatic movement of goods without manual direct handling, greatly improving the handling efficiency.

[0018] The support has a rotation function, which can drive the wheel to achieve synchronous rotation and flexibly adjust the conveying direction of the wheel according to actual needs. This feature allows operators to change the parking position of goods at will, and only by adjusting the conveying direction of the wheel, the goods can be effectively transported. It is suitable for various types of cargo handling devices, such as forklifts, carts, etc.

[0019] When the pallet panel is in a high position, it is used as a support plate without affecting its load-bearing function.

[0031] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0032] Embodiment 1 like Figure 1-Figure 8 As shown, in this embodiment, a storage pallet is provided, including a base plate 1, a pallet panel 2 and a height adjustment mechanism. The pallet panel 2 is arranged above the base plate 1 as a direct bearing surface for the goods. The material, size and shape of the pallet panel 2 can be selected and designed according to the nature of the goods and storage requirements; the base plate 1 is the bottom supporting structure of the pallet panel 2 and has sufficient strength and stability to carry the pallet panel 2 and the goods thereon.

[0033] A height adjustment mechanism is disposed between the base plate 1 and the pallet panel 2 for adjusting the distance therebetween. By operating the height adjustment mechanism, the height of the pallet panel 2 can be conveniently adjusted to meet the requirements of different storage environments or handling equipment. Under the action of the height adjustment mechanism, the height of the pallet panel 2 relative to the base plate 1 can be flexibly adjusted.

[0034] Among them, a plurality of rotating wheels 3 are rotatably mounted on the surface of the substrate 1, and the rotation directions of the plurality of rotating wheels 3 are the same, and the axes of the plurality of rotating wheels 3 are parallel to the surface of the substrate 1. When each rotating wheel 3 rotates, it can use the contact surface above it to push the goods to move along a specific direction. In the storage pallet panel 2 of the present invention, the directions of the plurality of rotating wheels 3 are designed to be the same, that is, their pushing directions extend along the same path. This design enables the rotating wheels 3 to collectively act on the goods on the pallet panel 2 when they rotate, generating thrust in the same direction, thereby effectively pushing the goods away from the pallet panel 2, realizing the automatic movement of the goods, without the need for manual direct handling, and the interior of the pallet panel 2 is provided with arc grooves adapted to the rotating wheels 3, which are grooves that penetrate the pallet panel 2, and these arc grooves provide a penetration path for the rotating wheels 3, and the upper end portion of the rotating wheels 3 can pass through these arc grooves, extend to the top of the pallet panel 2, and form contact with the goods placed on the pallet panel 2, and when the goods contact the rotating wheels 3, the rotating wheels 3 are rotated manually or mechanically, and the friction between the rotating wheels 3 and the goods will drive the goods to move in the horizontal direction. Since the pushing directions of the multiple rotating wheels 3 are the same, they can work together to push the goods along a predetermined path until the goods are completely pushed out of the pallet panel 2 .

[0035] When the pallet panel 2 is located far away from the base plate 1, the bearing surface of the pallet panel 2 is higher than the highest point of the upper end of the wheel 3, and part of the wheel 3 is located inside the circular arc groove; when the pallet panel 2 is located close to the base plate 1, the bearing surface of the pallet panel 2 is lower than the highest point of the upper end of the wheel 3. At this time, the wheel 3 is a supporting component for carrying goods, and whether the wheel 3 is in contact with the goods is determined by the up and down movement position of the pallet panel 2 relative to the base plate 1. When the storage pallet panel 2 is used to place goods, the pallet panel 2 is supported at a position far away from the base plate 1. At this time, the pallet panel 2 acts as a support plate. Although multiple circular arc grooves are designed inside to accommodate the wheel 3, these notches do not affect the function of the pallet panel 2 as a supporting surface. When the goods need to be moved away from the pallet panel 2, by releasing the supporting force of the support structure of the pallet panel 2, the pallet panel 2 will automatically move downward until the upper end of the wheel 3 passes through the circular arc groove and contacts the goods. Once the wheel 3 contacts the goods, the friction between the wheel 3 and the goods can be used to achieve horizontal movement of the goods by rotating the wheel 3. This design makes the cargo handling process automated and simple, eliminating the need for direct manual handling.

[0036] Embodiment 2 like Figure 1-Figure 8 As shown, based on the first embodiment, this embodiment provides a connection method between the substrate 1 and the tray panel 2, which is as follows: The surface of the base plate 1 is provided with a plurality of supports 4 that rotate in the horizontal direction, and the rotating wheel 3 is rotatably installed inside the support 4. The support 4 has a rotation function, and can drive the rotating wheel 3 to realize synchronous rotation, and flexibly adjust the transmission direction of the rotating wheel 3 according to actual needs, so that the goods can be guided to move in different directions without moving the storage pallet itself. This feature is mainly used in various types of cargo handling devices, such as forklifts, carts, etc. When using these devices to carry the goods on the pallet panel 2, the operator can change the parking position at will, and only needs to adjust the transmission direction of the rotating wheel 3 to align it with the handling device to achieve effective handling of the goods. The interior of the pallet panel 2 is provided with a plurality of circular holes that are matched with the rotating wheel 3 one by one, and a turntable 7 is rotatably installed in the circular hole, and a circular arc groove is provided inside the turntable 7. The turntable 7 can rotate freely in the circular hole, but it does not have the driving ability itself. When the support 4 drives the rotating wheel 3 to rotate, since part of the structure of the rotating wheel 3 is arranged inside the circular arc groove, this design makes the rotating movement of the rotating wheel 3 further drive the turntable 7 to rotate together.

[0037] Multiple supports 4 are arranged along the X-axis and Y-axis directions inside the base plate 1. By arranging multiple supports 4 along the X-axis and Y-axis directions on the base plate 1, the modular structure is realized, which is convenient for assembly and maintenance. A gear ring 5 is fixed on each support 4. A gear 6 is meshed and connected between any two adjacent gear rings 5 ​​in the X-axis direction. In the Y-axis direction, at least one row of gear rings 5 ​​is meshed and connected with a gear 6. The meshing connection between the gear rings 5 ​​and the gear 6 realizes effective transmission between the supports 4, which can ensure the precise and synchronous rotation of the rotating wheel 3 on the base plate 1. The gear 6 is rotatably installed inside the base plate 1. A motor driving any gear 6 to rotate is installed inside the base plate 1. By driving any gear 6 to rotate through the motor, the rotation state of the support 4 and the rotating wheel 3 in the whole system can be flexibly controlled to realize the multi-directional movement of the goods. When the motor is started, it will drive one or more gears 6 inside the base plate 1 to start rotating. Since these gears 6 are meshed and connected with the gear rings 5, they will drive the support 4 and the gear ring 5 connected thereto to rotate together. Since the gear ring 5 is fixed on the support 4, the rotation of the support 4 will further drive the rotating wheel 3 connected thereto to rotate.

[0038] Each support 4 is internally installed with a motor that drives the rotating wheel 3 to rotate. The function of the motor driving the rotating wheel 3 to rotate makes the rotating wheel 3 itself have a driving force, so that no manual intervention is required, and the goods above can be moved only by the rotation of the rotating wheel 3. The motor can be connected to the controller, and the controller is further connected to the automation equipment. The rotation of the rotating wheel 3 is precisely controlled by the programming software, and the rotating wheel 3 moves according to the programming instructions, thereby realizing the automatic operation. It should be noted that the specific controller and control software belong to the scope of the prior art and are not the innovation of the present invention, so the present invention will not elaborate on this aspect.

[0039] The pallet panel 2 includes a transverse plate and a skirt plate, the skirt plate is connected to the periphery of the transverse plate, and the pallet panel 2 is sleeved on the base plate 1 through the skirt plate, so that the pallet panel 2 can be stably sleeved on the base plate 1, and the skirt plate plays a role of fixing and supporting, ensuring the stability and load-bearing capacity of the pallet panel 2 during use. At the same time, the sleeve connection method also facilitates the disassembly and replacement between the pallet panel 2 and the base plate 1.

[0040] Embodiment 3 like Fig. 9 As shown, based on the first and second embodiments, this embodiment provides a driving method of the height adjustment mechanism, which is as follows: The height adjustment mechanism includes an oil chamber arranged inside the base plate 1, in which a slide plate 9 is slidably installed, and a sealing ring is provided on the surface where the slide plate 9 contacts the inner wall of the oil chamber. A connecting shaft 8 is fixed to the bottom of the cross plate, and the lower end of the connecting shaft 8 passes through the shell of the base plate 1 and is connected to the slide plate 9. An oil inlet pipe 10 and an oil outlet pipe 11 are connected to the oil chamber, and valves are installed on the oil inlet pipe 10 and the oil outlet pipe 11. Hydraulic oil is injected into the oil chamber through the oil inlet pipe 10 to push the slide plate 9 to move up and down, and the tray panel 2 is driven up and down by the slide plate 9 and the connecting shaft 8, thereby adjusting the height of the tray panel 2.

[0041] A flow limiting valve 12 is installed on the oil outlet pipe 11. A plurality of oil holes are arranged inside the flow limiting valve 12. The diameter of the oil holes is relatively small. The main function of the flow limiting valve 12 is to slow down the flow rate of the hydraulic oil, thereby controlling the descending speed of the pallet panel 2 and preventing rapid descent caused by carrying heavy objects. This can effectively reduce the impact force on the substrate 1 below the panel and avoid damage to the substrate 1.

[0042] There are multiple coupling shafts 8 , which are inserted into the gaps inside the base plate 1 . The multiple coupling shafts 8 support the tray panel 2 , increase the force range of the tray panel 2 , and protect the tray panel 2 .

[0043] Working principle: The design of the storage pallet integrates a base plate 1, a pallet panel 2, a height adjustment mechanism, and a rotating wheel 3 and a support 4 system, which together realize the automatic handling and height adjustment functions of the goods.

[0044] The pallet panel 2 is arranged above the base plate 1 as the direct bearing surface of the goods. Its material, size and shape are customized according to the characteristics of the goods. The base plate 1 provides a stable bottom support to ensure the safety of the pallet panel 2 and the goods thereon; the height adjustment mechanism is connected to the pallet panel 2 through the slide plate 9 and the connecting shaft 8 in the oil chamber. When hydraulic oil is injected into the oil chamber, the slide plate 9 moves up and down by the thrust, and drives the pallet panel 2 to adjust its height through the connecting shaft 8. The flow limiting valve 12 on the oil outlet pipe 11 controls the flow rate of the hydraulic oil, thereby adjusting the descending speed of the pallet panel 2 to protect the base plate 1 from impact.

[0045] The wheel 3 is rotatably installed inside the support 4, and the support 4 is arranged along the X-axis and Y-axis directions to realize a modular structure. A gear ring 5 is fixed on each support 4, and effective transmission between the supports 4 is realized through the meshing of gears 6 to ensure that the wheel 3 rotates synchronously. The motor drives the gear 6 to rotate, thereby driving the support 4 and the wheel 3 to rotate, pushing the goods to move in a specific direction. The turntable 7 is designed in the circular hole inside the pallet panel 2, and rotates with the wheel 3 but does not have driving ability, but enhances the flexibility of the structure.

[0046] When the pallet panel 2 is in a high position, it is used as a support plate and does not affect its load-bearing function. When the goods need to be moved, the pallet panel 2 is lowered, and the upper end of the wheel 3 passes through the arc groove to contact the goods, and the wheel 3 is rotated to use friction to push the goods to move in the horizontal direction until they are completely pushed out of the pallet panel 2.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
