Abstract
Description
Technical Field
[0001] This application relates to the field of warehousing and transfer equipment technology, specifically to a stacking and transfer device. Background Technology
[0002] Corrugated cardboard factories require substantial storage space for raw materials and finished cardboard, making automated storage and retrieval systems (AS / RS) the ideal carrier for high-level, high-density storage. Current technologies, employing double-decker trolleys and conveyor belts to transport corrugated paper, can only achieve 2-3 layers of transfer, failing to meet the industry's demands for multi-layer buffering and high-level storage in AS / RS. Furthermore, traditional equipment suffers from limited functionality; warehouse cranes only perform storage, and transfer vehicles only perform transfer, making them inflexible in adapting to different operational scenarios and unable to meet the diverse logistics needs of corrugated cardboard production lines. Summary of the Invention
[0003] In view of this, the present application provides a stacking and transfer device, including a stacker crane and a conveyor. The conveyor is located on the loading platform of the stacker crane, and the loading platform is also equipped with forks. The stacking and transfer device has a first working mode and a second working mode. The first working mode is: the stacker crane docks with the automated warehouse rack structure, the forks extend, and the conveyor completes the storage and retrieval of materials on the rack. The second working mode is: the stacker crane disengages from the automated warehouse rack structure, the forks retract, and the conveyor realizes multi-level receiving and delivery of materials.
[0004] In one possible implementation of the first aspect described above, a control system is also included, which controls the stacker crane and the conveyor to work together and switches between a first working mode and a second working mode.
[0005] In one possible implementation of the first aspect described above, the conveyor includes a tracked conveyor, a roller conveyor, a chain conveyor, and / or a mesh belt conveyor.
[0006] In one possible implementation of the first aspect described above, the stacker crane further includes a traveling unit for driving it to travel along the track and a lifting unit for driving the cargo platform and the conveyor to lift synchronously.
[0007] In one possible implementation of the first aspect described above, the two-way / four-way shuttle can pick up and place goods on the loading platform using forks; the two-way / four-way shuttle is equipped with an execution unit for picking up and placing materials; the stacker crane and the two-way / four-way shuttle work together to realize the changing of layers and the storage and retrieval of goods by the two-way / four-way shuttle.
[0008] Based on the technical solution of this application, when connected to the steel structure racks of an automated warehouse, the stacking and transfer device can function as a professional stacking equipment to complete high-level storage and retrieval of cardboard and dense warehousing; when matched with a cardboard logistics module with a conveyor line, the stacking and transfer device can directly transform into a multi-level lifting trolley to complete workshop transfers; neither mode requires additional modification to the main equipment, and switching is convenient, completely breaking the single-function barrier of traditional equipment where "warehouse machines can only store, and transfer vehicles can only transfer". Furthermore, the single / double-track stacker crane in this application can be quickly switched according to the cardboard size and the width of the automated warehouse aisles, adapting to the multi-specification logistics needs of corrugated cardboard production lines. Attached Figure Description
[0009] Figure 1 According to some embodiments of this application, a schematic diagram of a monorail stacking and transfer device is shown. Detailed Implementation
[0010] This application includes, but is not limited to, a stacking and transfer device. The specific solutions of this application's embodiments will be described below with reference to the accompanying drawings.
[0011] The conveyors described in this application include, but are not limited to, tracked conveyors. For example, roller conveyors can be used for unit materials requiring precise position control; chain conveyors can be used for heavy-duty pallets. These alternatives can all achieve integration and synchronous lifting with stacker cranes, falling within the scope of protection of this application. For ease of description, this application uses tracked conveyors as an example. Example 1
[0012] Figure 1 A schematic diagram of a monorail stacking and transfer device is shown. Figure 1 As shown, the stacking and transfer device includes a monorail stacker 1 and a tracked conveyor 2. The stacker 1's traveling unit 12 drives its entire assembly to move along a single track 3 laid on the ground. A lifting unit 13 (such as a chain or wire rope) drives the loading platform 11 and the tracked conveyor 2 fixed thereon to move vertically and synchronously. The loading platform 11 includes forks 21 that can extend to both sides. The tracked conveyor 2 includes tracks 22. The forks 21 and tracks 21 are arranged alternately, and the combination of the forks 21 and tracks 22 is not limited here. The stacking and transfer device also includes a control system, which controls the collaborative operation of the stacker 1 and the conveyor 2 and switches between a first working mode and a second working mode.
[0013] When it is necessary to enter the automated warehouse racking structure for operation, drive the stacker transfer device into the aisle to align the stacker crane 1 with the rack column. The control system switches to the first working mode, i.e., the storage mode. The lifting unit 13 lifts the conveyor 2 to the target storage layer, and the forks 14 extend to retrieve the cardboard from the storage location onto the conveyor 2, or vice versa, to send the cardboard from the conveyor 2 into the storage location.
[0014] When transfer is required within the workshop, the control system switches to the second working mode, namely the transfer mode. The lifting unit 13 adjusts the conveyor 2 to the height of the corresponding layer of the module belt. The conveyor 2 starts, and the cardboard can be received or sent out. The stacker 1 can move along the track to different stations for operation.
[0015] It is understood that the stacking and transfer devices provided in this application include, but are not limited to, single-track stacking and transfer devices, double-track stacking and transfer devices, and multi-track stacking and transfer devices. For ease of description, this application will use the single-track stacking and transfer device as an example. In some embodiments, the stacker crane 1 has a double-track structure, and its walking unit 12 drive device runs along two parallel tracks 3. The double-track structure provides better stability and load-bearing capacity, and is suitable for handling wider and heavier large corrugated cardboard stacks.
[0016] Thus, when connected to the steel structure racks of an automated warehouse, the stacking and transfer device can function as a professional stacking equipment for high-level storage and retrieval of cardboard and dense warehousing. When matched with a cardboard logistics module with a conveyor line, the stacking and transfer device can directly transform into a multi-level lifting trolley to complete workshop transfers. Neither mode requires additional modifications to the main equipment, and switching is convenient, completely breaking the traditional single-function barrier of "warehouse cranes can only store, and transfer vehicles can only transfer." Furthermore, the single / double-rail stacker crane in this application can be customized according to the cardboard size and the width of the automated warehouse aisles, adapting to the multi-specification logistics needs of corrugated cardboard production lines. Example 2
[0017] Building upon Example 1, to further improve access efficiency and flexibility, a bidirectional shuttle can be integrated into the stacker crane's cargo platform. For example... Figure 1 As shown, a fork 21 is provided on the loading platform 11. A two-way / four-way shuttle (not shown in the figure) is placed on the loading platform by extending and retracting the fork 21. The two-way / four-way shuttle is equipped with a pallet lifting unit, a cargo conveying unit, or a telescopic fork as its execution unit.
[0018] In the first operating mode, i.e., the warehousing mode, the stacker crane 1 carries the shuttle car to the target cargo column and elevates it to the target height. Subsequently, the stacker crane 1 remains stationary, and the forks 21 on the loading platform 11 place the shuttle car onto the shuttle track on the rack. The shuttle car then enters the designated track to complete the picking and placing of goods. It can be understood that a single stop by the stacker crane 1 can serve multiple consecutive storage locations at that height, as well as multiple consecutive storage locations across multiple levels of the same column, significantly reducing the number of times the stacker crane's main carriage travels and elevates, thus improving operational efficiency.
[0019] In the second working mode, namely the transfer mode, the stacker crane 1 is responsible for switching between different floor heights, and the shuttle car is responsible for storing and retrieving different cargo locations within each floor. The two work together to achieve fully automated management of this buffer area.
[0020] Thus, by integrating bidirectional / four-directional shuttles on the loading platform, the stacker crane 1 only needs to carry the shuttles to the target layer and precisely stop them in front of the corresponding cargo area. Subsequently, the forks 21 on the loading platform place the shuttles on the predetermined tracks, precisely aligning them with and serving multiple consecutive cargo locations on that layer, thereby improving the overall efficiency of the stacking and transfer device.
