Description

Technical Field

[0001] This utility model relates to the field of wear-resistant technology for sorting equipment, specifically a wear-resistant structure for a sorting trolley. Background Technology

[0002] The AGV (Automated Guided Vehicle) sorting trolley carries packages on a pallet. The trolley moves the packages to a predetermined location and then flips the pallet to transfer the packages to the corresponding sorting channel. Because the pallet is made of plastic, the surface and edges of the pallet become rough and burr-like as the packages slide down it. The worn surface and edges increase friction, causing the packages to not slide smoothly on the pallet. This can cause packages to get stuck, requiring manual intervention, thus reducing sorting speed and efficiency. Utility Model Content

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, a wear-resistant structure for a sorting cart includes: Vehicle body 1, vehicle body 1 is movable; Pallet 2 is mounted on vehicle body 1 and can be flipped on vehicle body 1. A support portion is provided on the pallet 2, and the support portion is used to reduce the contact area between the pallet 2 and the package 14; The lubrication section is used to lubricate the support section.

[0019] The vehicle body 1 has a movement module, a control module, a power storage module, and other functional modules. Through these various functional modules, the movement of the vehicle body 1 can be controlled. When the vehicle body 1 is moving, it can carry the package 14 to a predetermined position via the pallet 2, and then deliver the package 14 on the pallet 2 by flipping the pallet 2. Since the vehicle body 1 and the above-mentioned functional modules are all existing technologies, such as AGV handling robots, their specific structures and principles will not be described in detail.

[0020] Furthermore, a fixing plate 4 is provided at one end of the lower surface of the tray 2. The fixing plate 4 is rotatably connected to the vehicle body 1. A through groove for the fixing plate 4 to swing is provided on the upper surface of the vehicle body 1. The lower end of the fixing plate 4 is arc-shaped and has teeth evenly arranged on the lower end. A motor 5 is provided inside the vehicle body 1. The output end of the motor 5 is provided with a gear 6. The gear 6 meshes with the teeth on the fixing plate 4. A fixing block 3 is provided on the vehicle body 1, and the tray 2 can be placed on the fixing block 3.

[0021] When transferring package 14 via vehicle body 1, package 14 needs to be placed on pallet 2. When placing package 14 on pallet 2 into the designated position, pallet 2 needs to be controlled to flip. Specifically, by starting motor 5, gear 6 is driven to rotate. Gear 6 meshes with the teeth on fixed plate 4, driving fixed plate 4 to rotate. The rotation angle of fixed plate 4 is in the range of 40°-50°. After fixed plate 4 rotates, it will drive pallet 2 to rotate, so that package 14 on pallet 2 slides down along pallet 2 to the predetermined position, thereby transferring package 14 on pallet 2 out.

[0022] Motor 5 can be a servo motor. The fixed plate 4 can be rotated at an appropriate angle by a servo driver, PLC, encoder, PID algorithm, etc., thereby controlling the tilt angle of the tray 2. As long as the package 14 on the tray 2 can slide off the tray 2, the rotation angle does not need to be very precise.

[0023] The fixing block 3 is used to support the pallet 2. The fixing block 3 and the fixing plate 4 can support the pallet 2 to ensure that the surface of the pallet 2 remains level, which facilitates the safe and stable transportation of the package 14.

[0024] The size of the package 14 transported by pallet 2 must not exceed the edge of pallet 2 to ensure stable and efficient transport of package 14.

[0025] The weight of the lower end of the fixing plate 4 is greater than the weight of the upper end of the fixing plate 4, so as to provide a balancing effect on the rotation of the pallet 2, making the flipping of the pallet 2 more stable.

[0026] After the package 14 on the tray 2 is transferred out by controlling the flipping of the tray 2, the gear 6 is rotated in reverse by the motor 5 to reset the tray 2 so that the package 14 can be transferred again. At the same time, the forward and reverse rotation, start and stop, and movement speed of the motor 5 are controlled by the corresponding control module.

[0027] Furthermore, the support includes semi-circular protrusions 7 evenly distributed on the upper surface of the tray 2, and an installation groove is reserved in the middle of the tray 2.

[0028] The protrusions 7 reduce the contact area between the package 14 and the pallet 2, thereby reducing the friction when the package 14 slides off the pallet 2. This helps protect the pallet 2 and the package 14, and allows the package 14 to slide off the pallet 2 in one go, avoiding the need for repeated flipping of the pallet 2 or manual intervention to transfer the package 14 off the pallet 2.

[0029] Furthermore, the lubrication unit includes an atomizer 8, which is disposed inside the vehicle body 1. The atomizer 8 has a liquid storage chamber 9, which has a liquid inlet 10 disposed outside the vehicle body 1. The atomizer 8 also has an atomizing nozzle 11, which is disposed in a mounting groove on the tray 2. The atomizing nozzle 11 is connected to the atomizer 8 via a flexible pipe 12.

[0030] The liquid storage chamber 9 contains colorless and transparent lubricating oil. The atomizer 8 has a pressure balance port to balance the air pressure in the liquid storage chamber 9, so that the lubricating oil in the liquid storage chamber 9 can be effectively extracted.

[0031] Specifically, the atomizer 8 and atomizing nozzle 11 can spray the lubricating oil in the reservoir 9 vertically upward in a spray manner. When the lubricating oil is sprayed upward, the vehicle body 1 is in a stopped state and in a windless state, so that the sprayed atomized lubricating oil can fall back onto the tray 2 after being sprayed and adhere to the surface of the protrusion 7 on the tray 2. The lubricating oil sprayed on the protrusion 7 can further reduce the friction between the package 14 and the tray 2, thereby further reducing the wear of the package 14 and the tray 2.

[0032] Lubricating oil can be added to the protrusion 7 at regular intervals or in fixed frequency.

[0033] Each spray of lubricating oil has a volume of approximately 2 ml and a spray height of 30 cm. The atomized lubricating oil, after falling, can completely cover the upper surface of tray 2.

[0034] Furthermore, the vehicle body 1 is provided with an observation window 13, through which the liquid level in the liquid storage chamber 9 can be observed.

[0035] It is convenient to observe the level of lubricating oil in the reservoir 9, and lubricating oil can be easily added to the reservoir 9 through the inlet 10.

[0036] Furthermore, the height of protrusion 7 is higher than the height of atomizing nozzle 11.

[0037] Try to avoid direct contact between the package 14 and the atomizing nozzle 11 to reduce the possibility of the atomizing nozzle 11 becoming clogged.

[0038] Furthermore, both tray 2 and protrusion 7 are made of plastic, and tray 2 and protrusion 7 are integrally injection molded.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
