Description

Technical Field

[0001] The invention relates to a pallet device suitable for transporting wheeled box cargo and a transport method thereof, belonging to the field of logistics and warehousing. Background Art

[0002] Pallet conveyors are a common unit carrier in the cargo storage and sorting operations of the e-commerce and logistics express delivery industries. Currently, these conveyors are primarily suitable for box packaging and bulk materials, and there are no pallet conveyors specifically designed for transporting wheeled boxes.

[0003] Due to the growing diversity of cargo shapes and sizes, the packaging and transportation of goods in wheeled containers has become commonplace, typically using cage trucks and carts. However, due to the limitations of existing wheeled container transfer conveyor lines, manual assistance is often required during the transfer process, resulting in low efficiency and high operating costs.

[0004] For example, the prior patent application that discloses the following content, application number CN201520253295.3, is titled "A Transfer Bracket for Wheeled Goods," and includes a pallet, a fence, and a movable ramp. The pallet is provided with fences on three sides, and the movable ramp is provided on the side of the pallet without a fence. One side of the movable ramp is hinged to the pallet via a movable hinge, and the ends of the fences on both sides of the pallet near the movable ramp are connected to the two ends of the movable ramp via chains. Multiple slots for placing movable rods are symmetrically provided on both sides of the pallet surface, and the fences are also provided with an upper fixed cross bar. By providing a movable ramp at one end of the pallet of the bracket and a slot for placing movable rods on the surface of the pallet, goods can be conveniently transported into the bracket via the movable ramp and secured therein.

[0005] Although the above application scheme can fix and limit the wheeled box, the manual fixing method of the slot and the movable rod requires on-site workers to assist in pushing the goods into the bracket and inserting the movable rod into the slot to limit the position, so it has many disadvantages: First, the degree of transfer automation is low, and manual assistance is required for the entire transfer process, and the transfer efficiency is low; second, the number of slots and the spacing density cannot be applicable to all box dimensions, which limits the types and volumes of the transferred goods; third, the transfer is limited to the same vertical height, which limits the design and application of the conveyor line structure and transfer method.

[0006] In view of this, this application is hereby filed. Summary of the Invention

[0007] The wheeled box transfer device and method described in this invention address the aforementioned existing problems by proposing a novel pallet conveyor design suitable for transporting a wide variety of wheeled boxes. This transfer device implements vertical lifting and positioning of the box and horizontal transport, thereby meeting the requirements for transferring goods between conveyor lines with vertical drop differences.

[0008] In order to achieve the above design objectives, the transfer device of the wheeled box includes a fixed tray, a lifting tray, a transverse conveying component and a lifting component.

[0009] The fixed tray has a stopper for limiting the parking position of the wheeled box, and a number of evenly and symmetrically distributed perforations;

[0010] A plurality of symmetrically mounted lifting rods are provided on the lifting tray, and each lifting rod is connected to a through hole through a guide rail;

[0011] The transverse conveying assembly comprises a frame assembly and a driving assembly. A double-row chain is installed on the frame assembly, and the lifting tray is integrally connected to the double-row chain.

[0012] Furthermore, an anti-slip pad is provided on the top end of the jacking rod.

[0013] Furthermore, the lifting assembly comprises a cargo platform at the top, a chassis at the bottom, and a lifting arm installed therebetween and a connecting rod mechanism consisting of an oil cylinder and a hydraulic station.

[0014] Furthermore, the frame assembly of the transverse conveying assembly includes an integral frame consisting of a crossbeam weldment and a connecting beam, a double-row chain and an end sprocket assembly for winding the double-row chain are installed on the crossbeam weldment, and a guide rod is installed on the side of the crossbeam weldment.

[0015] Furthermore, the drive assembly of the transverse conveying assembly includes a drive motor, and a motor sprocket, chain, and conveying shaft connected by the drive motor. The drive sprocket and the tensioning sprocket at the end of the conveying shaft are entangled and drive the double-row chain to run.

[0016] Based on the above-mentioned structural improvements of the transfer device, this application also proposes a method for transferring a wheeled box. The method includes the following steps:

[0017] 1) Loading the pallet

[0018] In the initial state of transport, the wheeled box is transported to the fixed pallet, and the stopper on the fixed pallet limits the parking position of the box;

[0019] 2) Lifting and positioning

[0020] The hydraulic mechanism of the lifting assembly lifts the lateral conveying assembly and the lifting tray to the maximum height at the same time, and the lifting rod supports and positions the wheeled box;

[0021] 3) Horizontal conveying

[0022] The horizontal conveying component can transport the lifting pallet, fixed pallet and box body horizontally to the next workstation;

[0023] 4)Transshipment

[0024] The wheeled box is transferred to another conveyor line, the lifting assembly descends, and the transverse conveying assembly returns horizontally to the initial position, waiting for the next transfer process.

[0025] In the above steps, the fixed tray has several evenly and symmetrically distributed through-holes, and the lifting tray is provided with several symmetrically installed lifting rods, each of which is connected to the through-hole through a guide rail, and an anti-slip pad is provided at the top of the lifting rod.

[0026] In the above-mentioned horizontal conveying step, the driving motor of the driving assembly transmits the motor torque to the double-row chain, and the lifted wheeled box and the fixed pallet are transported horizontally to the next workstation together under the drive of the lifting pallet.

[0027] In the above-mentioned horizontal conveying step, the lateral conveying component, the driving sprocket at the end of the conveying long axis of the driving component and the tensioning sprocket are wrapped around and drive the double-row chain to run, and the lateral conveying component carries the lifting pallet, the fixed pallet and the wheeled box together for conveying and transferring in the horizontal direction.

[0028] In summary, the transfer device and transfer method of the wheeled box described in this application have the following advantages:

[0029] 1. The entire process of cargo loading, positioning, and transportation is automated without manual intervention or assistance, which not only improves the efficiency of on-site transportation operations, but also saves labor and reduces operating costs to the greatest extent.

[0033] 5. The overall structure is simple and easy to operate, and the equipment is easy to inspect and maintain on site. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The fixed tray 10 is arranged vertically above the lifting tray 20, and the transverse conveying assembly 30 is installed vertically above the lifting assembly 40. The transverse conveying assembly 30 is driven and connected to the lifting tray 20;

[0042] The fixed tray 10 has a stopper 6 for limiting the parking position of the wheeled box 50, and a plurality of evenly and symmetrically distributed through-holes 1;

[0043] A plurality of symmetrically mounted lifting rods 2 are provided on the lifting tray 20 . Each lifting rod 2 is connected to the through-hole 1 via a guide rail 4 . The guide rail 4 provides a vertical path guide for the lifting rod 2 during its passage through the through-hole 1 .
