Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to an automated warehouse. Background Technology

[0002] With the rapid development of casting 3D printing technology and the increasing demand for automated production, higher requirements are being placed on the allocation of sand core locations, storage management, retrieval efficiency, and the intelligentization of the core assembly process. Currently, sand cores on production lines are mostly stored using automated racking systems for classification. However, the process of storing and retrieving sand cores still mainly relies on manual searching and forklift operation. This not only results in a serious waste of human resources, but also the storage location strategy is not effectively linked to the 3D printing process parameters, leading to low overall scheduling efficiency. In existing technologies, automated racking systems are generally quite tall, making storage and retrieval operations difficult and requiring high performance from forklift equipment and skilled driving techniques from operators, posing certain safety risks. At the same time, because sand cores themselves have low strength and are prone to moisture absorption or breakage, existing storage systems lack specific protective measures such as moisture-proofing and impact-proofing designed for their material characteristics. Summary of the Invention

[0003] In view of the problems of low automation in sand core storage and high risk of sand core access, it is necessary to propose an automated storage and retrieval system and its operation process to realize the automated storage and retrieval of sand cores.

[0004] An automated storage and retrieval system (AS / RS) includes a main frame, storage compartments, and a drive mechanism. The main frame is fixed to the ground to ensure overall stability. The drive mechanism is mounted on the main frame, which provides support for it. The storage compartments are positioned on the drive mechanism, which moves them vertically relative to the main frame, thus adjusting their position. Each storage compartment can hold one sand core, providing an independent storage location for each sand core and facilitating its loading and unloading.

[0005] Furthermore, the main frame includes a first main frame and a second main frame. The first main frame includes four first columns and two first beams. The two first beams span the two opposing first columns, forming two opposing truss structures. The second main frame is installed on the first main frame. Specifically, the two second main frames are respectively installed on the two opposing truss structures through the two first beams. The second main frame is also used to improve the overall strength of the main frame and prevent the automated warehouse from shaking during operation.

[0006] Furthermore, the driving device is mounted on the second main frame. The driving device includes a first annular guide rail, a second annular guide rail, two sets of sliding components, several storage location support mechanisms, and two sets of power components. The two sets of sliding components and the two sets of power components are respectively mounted on the first annular guide rail and the second annular guide rail. The driving device is mounted on the second main frame via the power components, and the first and second annular guide rails are connected by the power components to form a fixed-distance, opposing structure. The storage location support mechanisms are fixedly mounted on the sliding components, and the power components drive the sliding components to rotate along the first and second annular guide rails. This structural arrangement enables the adjustment of the storage location's height within the automated storage and retrieval system.

[0007] Furthermore, the first annular guide rail has the same structure as the second annular guide rail. The first annular guide rail is composed of two annular structures, forming a groove to accommodate the sliding component.

[0008] Furthermore, the sliding assembly includes several connecting rods that are connected end to end and sliders at the hinge points of the connecting rods. The sliding assembly is rotatably connected to the first annular guide rail or the second annular guide rail via the sliders.

[0009] Furthermore, the power assembly includes a motor, a reducer, a first bearing housing, a drive wheel, a drive shaft, a second bearing housing, a driven wheel, a driven shaft, and a turntable. Two sets of the first and second bearing housings are symmetrically arranged. The two sets of first bearing housings are connected by the drive shaft and are mounted on the second main frame. The two sets of second bearing housings are connected by the driven shaft and are mounted on the second main frame. The first bearing housing is vertically positioned above the second bearing housing. Two drive wheels are located at both ends of the drive shaft, and two driven wheels are located at both ends of the driven shaft. A turntable is provided between the driving wheel and the second bearing seat. Both the turntable and the driven wheel are mounted on the driven shaft. The outer edge of the turntable is evenly provided with several grooves. The grooves cooperate with the slider to drive the sliding assembly to rotate along the second annular guide rail and the second annular guide rail. The reducer is located outside the first bearing seat and on the driving shaft. The motor is located outside the reducer and on the driving shaft, thereby realizing that the motor drives the driving shaft to rotate, the driving shaft drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate via a chain, the driven wheel drives the turntable to rotate, and the turntable drives the sliding assembly to rotate along the first annular guide rail and the second annular guide rail.

[0010] Furthermore, the storage location support mechanism is set between any two adjacent sliders and is fixedly connected to the two sliders, so that the sliders drive the storage location support mechanism to slide along the first annular guide rail and the second annular guide rail, which means that the position of the storage location in the automated storage and retrieval system can be adjusted and changed.

[0011] Furthermore, the storage support mechanism is also provided with a storage space, which is a cuboid or cubic space in whole, including a support crossbar, an outer frame and a base. The outer frame forms the accommodating space of the storage space, the support crossbar is set on the upper part of the outer frame, and the base is set on the bottom of the outer frame in the direction of the accommodating space. The base is used to support the tray that holds the sand core, so as to facilitate the placement and removal of the sand core.

[0012] An automated storage and retrieval system (AS / RS) operation process includes a sand core inbound process and a sand core outbound process. The inbound process is used to store sand cores prepared by the molding production line into the AS / RS, realizing the sand core inbound process. The outbound process is used to remove the sand cores stored in the AS / RS for the next process, realizing the sand core outbound process.

[0013] Furthermore, the warehousing process includes, S01, a gantry robot is used to place the sand core with assembled chills onto the sand core buffer platform; S02, the AGV transfer equipment transfers the sand core to the entrance and exit of the automated warehouse according to the warehousing instruction, and the automated warehouse rotates the storage position to the entrance and exit of the automated warehouse according to the warehousing instruction, so as to achieve the purpose of storing the specific sand core in the designated location; S03, Once the storage location of the automated warehouse is in position relative to the entrance / exit of the automated warehouse, the AGV transfer equipment will transfer the sand core to the designated location of the sand core in the automated warehouse along with the pallet and sand core according to the planned path. S04. After binding the sand core to the storage location of the automated warehouse, the sand core storage is completed.

[0014] Furthermore, in S01, the sand core buffer platform is provided with a tray for placing sand cores. The tray is provided with a sand core QR code, which allows the sand core to be placed on the designated tray, facilitating the recording of the sand core's position and the removal of the sand core.

[0015] Furthermore, the outbound process includes, S11, the automated storage system rotates the sand cores stored in the automated storage system to the automated storage system entrance and exit according to the outbound command; S12. After the sand cores are in position relative to the entrance and exit of the automated warehouse, the AGV transfer equipment will transfer the pallet together with the sand cores to the sand core buffer platform of the next process. S13, the gantry robot picks up the sand core and moves it to the next process, such as the core assembly process.

[0016] A molding production line includes several three-dimensional warehouses, which are set at the end of the sand core preparation process based on minimizing the transfer distance after sand core preparation.

[0017] Furthermore, the molding production line also includes a gantry robot, an AGV transfer device, and a sand core buffer platform. The gantry robot is used to transfer sand cores from the sand core preparation line to the sand core buffer platform or from the sand core buffer platform to the core assembly production line. The AGV transfer device is used to transfer sand cores to a designated location in the automated warehouse or from a designated location in the automated warehouse to the sand core buffer platform, thereby completing the warehousing and retrieval of sand cores.

[0018] The beneficial effects of the technical solution of this invention are as follows: By implementing the technical solution of this invention, automatic and location-based storage and retrieval of sand cores in an automated storage and retrieval system is achieved. Using an automated storage and retrieval system to store sand cores effectively saves storage and retrieval space. Furthermore, the rotational setting of the sliding component allows for real-time adjustment of the sand core position, facilitating random retrieval of sand cores. Attached Figure Description

Each storage location 3 can accommodate one sand core, providing each sand core with an independent storage position, facilitating the storage and retrieval of sand cores. In this embodiment, six storage locations 3 are provided on one AS / RS, meaning each AS / RS can store six sand cores, and the position of each sand core is fixed, allowing for random retrieval of stored sand cores based on a bound location code.

The slider 402 of the sliding component extends through the groove into the inner side of the first annular guide rail 401 and the second annular guide rail. One end of the slider 402 is fixedly connected to the connection of the two hinged connecting rods 404. The part protruding from the inner side of the first annular guide rail 401 and the second annular guide rail is used to connect the storage position support mechanism 403.
