Description

Technical Field

[0001] The invention relates to an automated management system for mold storage management, in particular to an automated mold library based on a shunting stacker. Background Art

[0002] The stereoscopic warehouse system is a combination of storage devices and control methods for efficient space utilization in the site. The stereoscopic warehouse not only plans the space in the horizontal direction but also makes reasonable use of the space in the height direction. The goods or other devices that need to be stored are reasonably placed in the space, which improves the storage space density and effectively utilizes the site space. In addition, in order to effectively utilize the space for the stored items, it is necessary to cooperate with the control device and its system to reasonably manage the storage information of the space and items, and call and clarify the process direction in time when necessary to improve the management level; molds are indispensable production equipment in industrial production. In mass production, molds have Excellent molding efficiency and molding accuracy, so the mold is closely related to product production. At the same time, due to the diversification of products, there are also a large number of supporting molds, and the molds need to be maintained and repaired, and the working time of the molds also needs to be recorded. If the molds are not managed well, it will increase the loss of the molds and affect normal production. The molds can be managed through a three-dimensional warehouse, but because of the large number of molds and the increase in the scale of storage shelves, the supporting control devices need to be increased accordingly, which not only increases the equipment investment cost, but also increases the floor area, which is not conducive to the reasonable management of the site. Therefore, there is a need for a mold library with a large number of suitable management, reasonable equipment investment and effective use of the site. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide an automated mold library based on a shunting stacker.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: the mold warehouse includes shelves, stackers, tracks, in / out warehouse conveyor lines and warehouse management software. The shelves are arranged in three dimensions in the site and are partitioned with a number of lanes for storing molds. At least two working channels are arranged between the shelves. A "U"-shaped track is connected between the two working channels. The straight part of the track is arranged in parallel in the working channel, and the arc part connects the two straight parts. The stacker moves on the "U"-shaped track and stacks goods in the two working channels. The in / out warehouse conveyor line is arranged at one end of the "U"-shaped track. The stacker moves to the in / out warehouse conveyor line and transports the molds in or out of the warehouse. The warehouse management software controls and manages the mold warehouse.

[0005] This design mainly arranges the shelves densely and reserves at least two working channels. Both sides of the working channels are directly connected to the lanes for storing molds. The working channels are connected by "U"-shaped tracks. The stacker moves on the track and can move freely in the two working channels. It is realized that one stacker can work in two working channels, which reduces the investment in stackers and reduces the floor space, and improves the storage density of the mold library. If there are more than two working channels, they can be connected end to end to form a coherent track structure. At the same time, since one stacker can work in all lanes, when the stacker needs to be shut down for maintenance, the spare stacker can be used to continue passing through without affecting normal work.

[0006] Furthermore, the stacker includes an upper crossbeam, a lower crossbeam, a vertical beam, a lifting device, a lifting rail, a cargo platform, a fork and a walking device. The upper crossbeam and the lower crossbeam are respectively arranged horizontally up and down and form a rectangular frame structure with the vertical beam. The frame structure moves and works on the lifting rail. The walking device drives the frame structure to move on the lifting rail. A cargo platform is arranged in the frame structure. The cargo platform changes its height in the frame structure through the lifting device. A lifting rail is arranged on the vertical beam. The cargo platform moves in a straight line along the lifting rail. The fork is connected to the cargo platform and extends horizontally to the side based on the cargo platform and extends into the lane.

[0007] The stacker is mainly used to transfer and stack the molds on the shelves. Since the shelves have many different aisles in the height and horizontal directions, the stacker can move in two directions through the walking device and the lifting device, so as to realize stacking at various positions. The work efficiency is high. The frame structure is formed by a rigid structure and forms a working space for the cargo platform. The cargo platform is used to load the molds for movement. The fork extends horizontally from the cargo platform into the aisle to realize stacking of goods in the aisle or taking goods out of the aisle.

[0008] Furthermore, the track is a sky-and-ground track structure, specifically comprising a supporting rail fixed on the ground and a corresponding guide rail fixed on the top of the space. The supporting rail and the guide rail are overlapped on the top projection plane, and the top and bottom of the stacker are in contact with and move between the supporting rail and the guide rail at the same time. The supporting rail is a solid "I"-shaped rail, and the guide rail is a strip structure with equal cross-section extension.

[0009] The track is a ground-rail structure with upper and lower lines set up, which guides and corrects the stacker at the same time. The support rail at the bottom has load-bearing and guiding functions, while the guide rail at the top provides more guidance and correction functions, allowing the stacker to run safely on the track and avoid deviation during operation.

[0010] Furthermore, the in / out warehouse conveyor line includes a lower conveyor platform, a pick / place workbench and an upper workbench, and all are composed of a roller table structure. A pick / place workbench is set at the end of the conveying direction of the lower conveyor platform, and an upper workbench is set at the end of the conveying direction of the pick / place workbench. The roller table drives the conveyed objects to run unidirectionally along the working direction. An inventory sensor is set on the pick / place workbench to sense the conveyed objects passing through it.

[0011] The in / out conveyor line is mainly used to manage, record and move in and out of the goods. The in / out conveyor line runs in one direction. The objects taken out from the shelf by the stacker are placed on the lower conveyor table and moved to the pick / place workbench. The pick / place workbench can take out or put in the mold. At the same time, the inventory sensor will sense whether the mold is taken out or placed, and detect whether the shape exceeds the limit, as well as other safety inspections. After passing the inspection, it enters the upper shelf workbench. The stacker transfers the objects from the upper shelf workbench and enters the shelf.

[0012] Furthermore, the shelves include shelf plates, cross beams, columns, vertical tie rods, horizontal tie rods and hanging beams. The columns are regularly arranged in a rectangular shape and fixed in the site. The columns are evenly spaced and set corresponding to the spacing between the aisles. Cross beams of different heights are set on the columns. The cross beams are set in the vertical direction of the columns corresponding to the height of the aisles. Shelf plates are installed between the cross beams. The shelf plates are set corresponding to the specifications of single storage units in the aisles. Vertical tie rods and horizontal tie rods are set on the back sides of the columns and the cross beams. The vertical tie rods and the horizontal tie rods fix the overall structure of the shelf in a perpendicular direction to each other. The hanging beam is set on the top of the shelf and serves as a fixed base for the guide rails.

[0013] The shelves are connected and fixed to each other through multiple structural parts to form a storage space, which effectively improves the storage efficiency of the shelves. The structure is stable and reliable, providing a structural foundation for the operating tracks and ensuring the overall safety of the equipment.

[0014] Furthermore, the warehouse management software manages data information such as the number of times the mold is issued, the number of times it is used, the inventory status, the usable life, and the physical photos. There are at least two storage units in each lane of the shelf. The warehouse management software uses the storage unit as the management unit and records the management data in the storage unit.

[0015] The warehouse management software can record a variety of mold data, which can effectively improve management efficiency. At the same time, it can detect mold loss, reasonably arrange production efficiency, and improve management efficiency.

[0016] Compared with the prior art, the present invention has the following advantages and effects: the equipment mainly arranges the shelves densely to leave at least two working channels, all the lanes of the shelves for storing molds are directly connected to the working channels, and the working channels are connected by a "U"-shaped track. The stacker moves on the track and can move freely in the two working channels, so that one stacker can work in two working channels, reducing the investment in the stacker and the floor space, and can also improve work efficiency, perform work backup, and avoid the problem of being unable to pass continuously.
