Description

Technical Field

[0001] This invention relates to the field of warehousing and logistics technology, and in particular to a four-way bin shuttle elevator. Background Technology

[0002] Elevators are used in the logistics industry and other applications requiring lifting, such as automated parking systems and freight elevators. They serve to lift and retrieve materials, greatly improving storage efficiency and space utilization while significantly reducing manpower and material costs. With the widespread application of intelligent logistics warehousing, more and more industries are building their own unmanned warehouses. Material retrieval from warehouse shelves requires connection to elevators. Four-way pallet shuttles remove palletized materials from the shelves and place them at the conveyor mechanism, where they connect with the elevator's conveyor system. The palletized materials then enter the elevator, which moves up and down to deliver the materials to the required height.

[0003] In existing technology, the conveying mechanism of a hoist typically employs a rectangular frame structure lifting platform, including a fixed frame, a lifting device, a lifting platform, and a horizontal conveying device. The lifting device comprises four sets of power components, a double-row sprocket assembly, a double-row chain, and a counterweight assembly. The four sets of power components are installed at the four corners of the bottom of the lifting platform, along with four sets of motor reducers and fixed gears on the reducer output shafts. The gears on the power components mesh with rack and pinion assemblies. The double-row sprocket assembly is fixed to the top frame and serves as the transmission structure for the double-row chain. The double-row chain runs parallel to the left and right sides of the top frame and meshes with the double-row chain. One end of the double-row chain connects to the lifting platform, and the other end connects to the counterweight assembly. Guide wheel assemblies are installed on the four corner sides of the lifting platform. During lifting, the platform is guided by the guide wheel assemblies sliding up and down along the column assembly. However, when handling materials with large volume and mass, due to the limitations of the aforementioned lifting platform and guide wheel assembly structure, the lifting platform is prone to swaying during lifting, and its stability needs improvement.

[0004] Therefore, in certain situations, such as applications involving the lifting of heavy objects or applications where objects inside the cargo box are swaying, existing lifting mechanisms cannot meet the stability requirements of cargo lifting and transportation. Thus, it is necessary to propose a four-way cargo box shuttle lift to solve the above problems. Summary of the Invention

Mounting frame 766, the buffer pad mounting frame 766 and the first crossbeam 761 of the trapezoidal support frame are both equipped with trapezoidal frame middle guide devices 79 and the second crossbeam 762 of the trapezoidal support frame and the third crossbeam 765 of the trapezoidal support frame; the four-way material box shuttle elevator of the present invention includes: a base drive component, a column frame component, a profile column component, a top frame component, a belt lifting component, a counterweight component and a bracket conveying component. By setting trapezoidal support frames above both ends of the bottom crossbeam of the bracket conveying component, and setting a pair of rubber-coated guide wheels above and below the outer side of the trapezoidal support frame, it can run up and down along the profile column component, avoiding the shaking caused by the lifting and lowering of the bracket conveying component when handling some large-volume and large-weight materials. The design of the trapezoidal support frame, by utilizing the structural characteristics of the trapezoidal support frame being narrow at the top and wide at the bottom, makes more of the weight of the trapezoidal support frame concentrated at the bottom, further improving the stability when handling large-volume and large-weight materials.

[0145] Specifically, an intermediate rod bearing plate 46 is installed on the intermediate rod 43. The intermediate rod bearing plate 46 is used to provide support at the contact point between the profile column component 3 and the intermediate rod bearing plate 46, so as to prevent the top of the profile column component 3 from deforming.

[0146] Specifically, both the long rod 41 and the short rod 42 are provided with rod bottom connectors 47 at their bottoms. The rod bottom connectors 47 are used to connect the plate column frame component 2. The outer wall contour of the rod bottom connectors 47 matches the outer wall contour of the plate column frame component 2.

[0151] Specifically, the counterweight 63 is rectangular, and the length of the counterweight 63 is less than the length of the counterweight guide beam 622. In actual use, the rectangular counterweight 63 can effectively avoid collisions between the outer wall of the counterweight 63 and other structures during its up-and-down movement due to the neat shape of its outer wall.

[0159] This application presents a four-way pallet shuttle lift, which functions to lift palletized materials, transport shuttles, and connect with other conveying equipment. With the widespread application of intelligent logistics warehousing, more and more industries are building their own intelligent automated warehouses. Material retrieval from warehouse shelves requires connection via a lift. The four-way pallet shuttle removes palletized materials from the shelves, places them at the conveying mechanism, and connects with the lift's conveying mechanism. The palletized materials enter the lift, which moves up and down to deliver the materials to the required height. The four-way pallet shuttle lift solves the problem of multi-level shelf access and the handling of large, heavy materials, achieving more efficient space utilization. The four-way pallet shuttle lift also functions as a load-bearing unit for four-way pallet shuttles. For multi-level automated warehouses, equipping each level with a shuttle increases operating costs. The four-way pallet shuttle lift can switch shuttles between levels, delivering them to designated storage levels, solving the problem of one shuttle handling multiple levels and significantly reducing user operating costs.

[0160] The four-way hopper shuttle elevator has a simple structure. The overall frame is mostly constructed using profile welding and sheet metal bending processes, making processing easy. Its symmetrical design facilitates installation and maintenance, and also contributes to equipment stability. The transmission and counterweight traction utilize synchronous belts or steel wire belts, resulting in smooth operation, low vibration, and virtually no noise compared to chains or gears.

Double steel wire connection for the counterweight, with each steel wire having a safety factor of six times; 3. Anti-collision and shock-absorbing blocks at the lower end of the counterweight and the upper end of the bracket and conveying components; 4. A protective net is installed at the front end of the elevator to prevent materials or shuttle cars from falling; 5. A cover is installed on the outside of the whole machine to avoid accidental injury during the operation of the counterweight; 6. Multiple safety photoelectric detectors, and the equipment cannot be started if any one of them is detected abnormally.

[0162] The four-way bin shuttle elevator of this invention is specifically designed to connect to a four-way pallet automated warehouse and work with a four-way pallet shuttle to complete the storage and retrieval of materials. This four-way bin shuttle elevator is designed for storing and transporting large-volume, high-mass materials, specifically meeting the requirements of a volume ≤1200mm×1100mm×1200mm (length×width×height), but not limited to these dimensions; and a load capacity ≤2.0T. The equipment can operate in environments ranging from -25°C to +40°C. This invention features multiple safety protections to enhance the safety factor of the device. The overall structure is simple and easy for operators to install and adjust. The four-way bin shuttle elevator of this invention adopts a symmetrical design, resulting in a stable and reliable overall structure. It can adapt to various height requirements, and the height can be adjusted according to actual usage needs. When increased height is required, the height of each component in this application's technical solution can be increased, along with the corresponding extension. Due to its stable structural design, this application's technical solution features heavy load capacity and large load volume.

[0163] The installation method of the four-way material box shuttle elevator of the present invention is as follows: First, install the column frame component 2 onto the base drive component 1, and install all fastening connectors in place; install the lower end of the profile column component 3 onto the base drive component 1, and fix the side to the column frame component 2; install the top frame component 4 onto the top of the column frame component 2; install the belt lifting component 5 in place, and adjust the tension by the screw to ensure consistent tension as much as possible; fix the bracket conveying component 7 to the belt lifting component 5 through connectors, and ensure the bracket is level by a leveling instrument, and adjust and clamp the side rubber-coated rollers to the profile column component 3; install the counterweight component 6 onto the side of the column frame component 2, and connect the other end of the counterweight component to the bracket conveying component 7 through a traction belt, and adjust by the adjusting screw to ensure that the counterweight is level and the traction belt is under consistent force. When splicing the guide rails on both sides of the counterweight, ensure that the joints are flat and without steps, and apply lubricating oil to the guide rails. Finally, assemble the safety photoelectric sensor group 9, the cover assembly 10, etc. in sequence.

[0164] The main functions of this invention are divided into three parts: storage, retrieval, and layer switching.

[0165] Storage: Upon receiving the command, the four-way pallet shuttle elevator starts its motor, and the tray conveyor component 7 descends. Through servo precision control and photoelectric assistance, it reaches the same height as the matching conveyor line, and the pallet material is conveyed to the elevator. The elevator receives the pallet material via the conveyor chain on its own tray, and the photoelectric control controls the material's stopping position. The elevator then ascends, aligning its height with the storage layer. The elevator conveyor mechanism delivers the material, which is then picked up by the four-way pallet shuttle and transported to the designated storage location.

[0166] Retrieve: the reverse operation of deposit.

[0167] Layer change: If palletized materials need to be stored in the fourth-level rack, but the four-way pallet shuttle is on the second level, the shuttle needs to be moved to the fourth level first by the four-way pallet shuttle elevator. The elevator runs to the second level and aligns with the second-level shuttle track. The shuttle then enters the elevator.
