AI Technical Summary
[0002]一些批量生产中小件产品的企业已经开始采用周转料箱存储产品，并通过自动输送线将装有产品的周转料箱存储到立体货架上；周转料箱具有易分类和可叠放的特点；随着自动化生产能力的不断提升，存储料箱的货架的规模也越来越大，出现了大型的存储周转料箱的自动化立体仓库；这些自动化料箱存储库是通过高速料箱堆垛机和多层横梁式立体货架组成的，在货架巷道内设置有地轨，在巷道顶端货架连接梁上设置有天轨，高速料箱堆垛机行走在天、地轨道之间，在立体库货架横梁上可叠放若干周转料箱；由于立体库货架上的周转料箱是高密度存放的，相邻周转料箱相互之间预留的货叉取货间隙均很小；当料箱堆垛机在巷道内高速运行时，会产生较大的振动，振动通过天轨与立体库货架会传导到货架横梁上，就会导致放置在横梁上的周转料箱由于振动而出现歪斜现象，被振动歪斜的周转料箱，在堆垛机取货时就会出现货叉与周转料箱配合不到位，造成货叉顶货的现象，甚至会发生周转料箱掉落现象；由于料箱堆垛机在巷道内运行时随着不同时间段的加、减速，振动频率不规则也不确定，这种共振很难被超前抑制，如何在保证料箱堆垛机正常运行的情况下抑制货架振动幅度，减少货架上的周转料箱发生歪斜概率，就成为自动化料箱库在使用中需要解决的一个技术难题
[0007]本发明通过在自动化料箱库货架立柱侧与横梁侧各固定连接一组阻尼装置，阻尼装置通过设置在阻尼弹簧消振杆两侧的重力阻尼锤相互抵消料箱库货架立柱与横梁在料箱堆垛机运行通过时产生的连带振动，使横梁上的周转料箱不再出现振动歪斜的现象。

Abstract
Description
Technical Field
[0001] This invention relates to an automated storage and retrieval system (AS / RS), and more particularly to an automated storage and retrieval system with a damping mechanism for storing turnover bins. Background Technology
[0002] Some companies that mass-produce small and medium-sized products have begun using storage bins to store their products, and these bins are then stored on automated storage and retrieval systems (AS / RS) via automated conveyor lines. These storage bins are easy to categorize and stack. With the continuous improvement of automated production capabilities, the scale of storage bin racks is also increasing, leading to the emergence of large-scale automated storage and retrieval systems (AS / RS). These automated storage and retrieval systems consist of high-speed stacker cranes and multi-layer beam-type AS / RS. Ground rails are installed within the rack aisles, and overhead rails are installed on the connecting beams at the top of the aisles. The high-speed stacker cranes move between these ground and overhead rails, and several storage bins can be stacked on the beams of the AS / RS racks. Because the storage bins on the AS / RS racks are stored at high density, forklifts are pre-installed between adjacent storage bins. The retrieval gaps are very small. When the stacker crane operates at high speed in the aisle, it generates significant vibration. This vibration is transmitted through the overhead rails and the automated warehouse racks to the rack beams, causing the turnover boxes placed on the beams to tilt due to the vibration. When the stacker crane retrieves the turnover boxes, the forks may not align properly with the turnover boxes, resulting in the forks pushing the boxes, or even the turnover boxes falling off. Because the stacker crane's vibration frequency is irregular and uncertain due to acceleration and deceleration at different times during operation in the aisle, this resonance is difficult to suppress in advance. How to suppress the vibration amplitude of the racks and reduce the probability of turnover boxes tilting on the racks while ensuring the normal operation of the stacker crane has become a technical problem that needs to be solved in the use of automated bin warehouses. Summary of the Invention
[0003] This invention provides an automated storage and retrieval system (AS / RS) for turnover bins that can effectively suppress the vibration of the storage location. It solves the technical problem of how to suppress the vibration amplitude of the racks while ensuring the normal operation of the bin stacker crane, thus ensuring the stable and safe operation of the high-density turnover bin AS / RS.
[0004] The present invention solves the above technical problems through the following technical solutions: An automated storage and retrieval system (AS / RS) capable of effectively suppressing vibrations in the storage locations of turnover boxes includes a left-side AS / RS rack and a right-side AS / RS rack for turnover boxes. A stacker crane aisle is provided between the left-side and right-side AS / RS racks. A ground rail is installed in the stacker crane aisle. A top rail is installed on the underside of the rack connecting beam directly above the ground rail. A high-speed stacker crane for transporting turnover boxes is installed between the ground rail and the top rail. A top rack is installed at the top of the left-side AS / RS rack. A transverse damper mounting base is installed on the horizontal beam frame at the bottom of the top rack. The middle part of a horizontally positioned transverse damping spring rod is connected to the transverse damper mounting base. A first transverse damping hammer is connected to one end of the transverse damping spring rod, and a second transverse damping hammer is connected to the other end of the transverse damping spring rod.
[0005] A vertical damper mounting base is installed on the vertical column of the top shelf. The middle part of the vertical damping spring rod, which is set along the vertical direction, is connected to the vertical damper mounting base. A third vertical damping hammer is connected to one end of the vertical damping spring rod, and a fourth vertical damping hammer is connected to the other end of the vertical damping spring rod.
[0006] The transverse damper mounting base is set on the crossbeam inside the aisle of the bottom horizontal beam frame of the top shelf; the vertical damper mounting base is set on the outer side column of the three-dimensional shelf on the left side of the turnover bin on the top shelf; the turnover bin is placed on the top shelf.
[0007] This invention fixes a set of damping devices to the uprights and beams of the automated bin storage rack. The damping devices use gravity damping hammers on both sides of the damping spring vibration damping rod to counteract the vibrations generated by the uprights and beams of the bin storage rack when the bin stacker passes by, so that the turnover bins on the beam no longer vibrate and tilt.

Figure 3 This is a structural schematic diagram of the top shelf 7 of the present invention. Detailed Implementation
[0009] The present invention will now be described in detail with reference to the accompanying drawings: An automated storage and retrieval system (AS / RS) for effectively suppressing vibrations in the storage locations of turnover boxes includes a left-side AS / RS 1 and a right-side AS / RS 2. A stacker crane aisle 3 is provided between the left-side AS / RS 1 and the right-side AS / RS 2. A ground rail 4 is installed in the stacker crane aisle 3. A top rail 5 is installed on the underside of the rack connecting beam directly above the ground rail 4. A high-speed stacker crane 6 for transporting turnover boxes is installed between the ground rail 4 and the top rail 5. A top rack 7 is installed at the top of the left-side AS / RS 1. A lateral damper mounting seat 9 is installed on the horizontal crossbeam frame 8 at the bottom of the top rack 7. Due to the dense arrangement of the racks, the lateral damper mounting seat 9 is generally installed on the beam inside the aisle or on the crossbeam outside the rack. The middle of the damping spring rod 10 is connected to the transverse damper mounting base 9. A first transverse damping hammer 11 is connected to one end of the transverse damping spring rod 10, and a second transverse damping hammer 12 is connected to the other end of the transverse damping spring rod 10. When the high-speed stacker crane 6 runs back and forth along the stacker crane traveling aisle 3, the high-speed stacker crane 6 itself will generate mechanical vibrations of different frequencies. These vibrations will be transmitted to the bottom horizontal beam frame 8 on the top rack 7 through the overhead rail 5, causing the bottom horizontal beam frame 8 to also generate vibrations of the same frequency. The transverse damping spring rod 10 installed on the transverse damper mounting base 9 has a certain degree of flexibility. The interaction between the transverse damping spring rod 10 and the first transverse damping hammer 11 and the second transverse damping hammer 12 connected to it will cancel out the up and down vibrations of the bottom horizontal beam frame 8 itself.
[0010] A vertical damper mounting base 14 is provided on the vertical column 13 of the top shelf 7. The middle part of the vertical damping spring rod 15, which is arranged in the vertical direction, is connected to the vertical damper mounting base 14. A third vertical damping hammer 16 is connected to one end of the vertical damping spring rod 15, and a fourth vertical damping hammer 17 is connected to the other end of the vertical damping spring rod 15. The vertical damping device connects the vertical damping spring rod 15, the third vertical damping hammer 16 and the fourth vertical damping hammer 17 on it to the vertical column 13 through the vertical damper mounting base 14. When the high-speed stacker 6 runs back and forth along the aisle, the mechanical vibrations of different frequencies generated by the high-speed stacker 6 itself are transmitted to the vertical column 13 through the overhead rail 4. The third vertical damping hammer 16 and the fourth vertical damping hammer 17 on the vertical damping device suppress the back-to-back and left-to-right swaying vibrations of the column by swinging back and forth and by the vibration damping effect of the vertical damping spring rod 15.
[0011] The lateral damper mounting base 9 is set on the crossbeam inside the aisle of the horizontal crossbeam frame 8 at the bottom of the top shelf 7, and the vertical damper mounting base 14 is set on the outer side column of the three-dimensional shelf 1 on the left side of the turnover box on the top shelf 7; multiple lateral damping devices and multiple vertical damping devices can be set according to the vibration conditions; turnover boxes 18 are placed on the top shelf 7, and the boxes can be stacked in multiple layers in the three-dimensional warehouse.
