Description

Technical Field

[0001] This utility model belongs to the field of automated warehouse racking technology, specifically relating to an automated warehouse racking double-layer adjustable foot device, an automated warehouse racking unit, and an automated warehouse racking. Background Technology

[0002] When designing automated warehouse (AS / RS) racking, considering the unevenness of the site ground and the possibility of uneven ground settlement in the future, as well as the extremely high installation precision requirements of AS / RS racking, adjustable foot devices are generally used for adjustment.

[0003] like Figure 1 As shown, the commonly used adjustable foot device (10) in the prior art includes a base plate (11) installed on the ground, multiple vertically arranged screws (12) fixed to the base plate (11), a union seat (13) located above the base plate (11) and passing through the multiple screws (12), and several adjusting nuts (14) threadedly connected to the screws (12). The union seat (13) is fixed to the two screws (12) by the adjusting nuts (14), and the lower end of the upright (20) is fixedly connected to the union seat (13). For the existing double-layer automated storage and retrieval system (AS / RS), the first and second layer sub-rails (30) are both installed on shuttle beams (40) bolted to the uprights (20), and goods are stored on the sub-rails (30).

[0004] The existing technology adjusts the height of the first-layer sub-track (30) of the automated storage and retrieval system (AS / RS) by rotating the adjusting nut (14) on the screw (12). The distance between the two layers of sub-tracks (30) can only be adjusted by the standard pitch of the upright (20), and the adjustment gap is limited, making it a single-layer adjustable foot device. With the development of the AS / RS market, the height of old factory buildings is limited, and the requirements for compressing the height of the racks are increasing. The existing method of installing the two layers of sub-tracks (30) on the upright (20) has a certain height from the ground for the first layer of sub-tracks (30), and the adjustment gap of the second layer of sub-tracks (30) is limited, which affects the overall height of the AS / RS racks and makes it difficult to meet the increased requirements for compressing the rack height.

[0005] A search revealed no publicly available technical solutions similar to this utility model. Utility Model Content

[0006] To address the technical problems existing in the prior art, the first aspect of this utility model is to provide a double-layer adjustable foot device for automated storage and retrieval systems (AS / RS). The second aspect, based on the same inventive concept, is to provide an AS / RS unit based on the aforementioned adjustable foot device. The third aspect, based on the same inventive concept, is to provide an AS / RS based on the aforementioned AS / RS unit.

[0007] In this embodiment of the utility model, the double-layer adjustable foot device for the automated storage and retrieval system includes a base plate installed on the ground, a plurality of vertically arranged screws fixed to the base plate, a support plate located above the base plate and passing through the plurality of screws for installing the first layer of sub-tracks, and a movable joint seat located above the support plate and passing through the plurality of screws for installing the uprights. Each screw is threaded with a first adjusting nut located on both sides of the support plate for fixing the support plate, and a second adjusting nut located on both sides of the movable joint seat for fixing the movable joint seat.

[0008] The automated storage and retrieval system (AS / RS) unit of this utility model includes two rows of adjustable feet installed on the ground at intervals, two rows of opposing columns fixedly installed on the adjustable feet on the adjustable feet, several shuttle beams connected to the two columns at both ends by bolts, and at least two layers of sub-tracks installed on the two columns at intervals along the height direction. The two sub-tracks of each layer are respectively installed on the two columns and are opposite to each other. Goods are stored on the two sub-tracks of each layer. The bottom first layer of sub-tracks is fixedly connected to several first mounting brackets that are spaced apart along its length and correspond one-to-one with the support plates. The second and above sub-tracks are fixedly connected to several second mounting brackets that are spaced apart along their length and fixed to the shuttle beams.

[0009] The automated storage and retrieval system (AS / RS) rack of this utility model includes several AS / RS rack units, which are arranged side by side along the width direction of the AS / RS rack units.

[0010] Compared with the prior art, the beneficial effects of the superior technical solution of this utility model include:

[0011] 1. This utility model sets up a support plate and installs the first layer of sub-tracks on the support plate, so that the adjustable foot device can not only adjust the height of the first layer of sub-tracks, but also adjust the height of the second layer of sub-tracks, thus constructing a double-layer adjustable foot device and a double-layer cascaded height adjustment system.

[0012] 2. The height of the first layer of sub-rails can be adjusted by rotating the first adjusting nut, achieving the lowest adjustment value for the first layer of sub-rails. The height of the second layer of sub-rails can be adjusted by the standard pitch of the uprights and rotating the second adjusting nut, realizing a composite function of micro-distance coordinated adjustment between the two layers of sub-rails. Compared with the traditional single-layer adjustment scheme, this scheme saves the height space of the double-layer automated storage and retrieval system, bringing convenience to customers' storage.

[0013] 3. The first-layer sub-track is installed on the support plate of the adjustable foot device. The shuttle beam that traditionally supports the first-layer sub-track is integrated into the foot adjustment device, reducing the original shuttle beam of the first-layer sub-track and saving costs.

[0014] 4. The two adjacent uprights of two adjacent racking units are installed on the same adjustable foot device's joint seat, and the two adjacent first-layer sub-rails of two adjacent racking units are installed on the same adjustable foot device's support plate. That is, the adjacent nodes of two adjacent racking units are installed on the same adjustable foot device, forming a continuous load-bearing system and improving the overall rigidity of the racking.

[0015] 5. The first mounting brackets of the two adjacent first-layer sub-rails of two adjacent automated storage and retrieval system units are integrated. Compared with the two first mounting brackets being fixed to the support plate separately, the integrated installation can improve the connection strength and the overall rigidity of the automated storage and retrieval system.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] This embodiment provides a double-layer adjustable foot device for automated storage and retrieval systems, such as... Figure 2As shown, in a preferred embodiment, the double-layer adjustable foot device 10 includes a base plate 11 installed on the ground (the base plate 11 can be fixed to the ground by expansion bolts), a plurality of vertically arranged screws 12 fixed to the base plate 11, a support plate 15 located above the base plate 11 and passing through the plurality of screws 12 for installing the first layer sub-track 30, and a union seat 13 located above the support plate 15 and passing through the plurality of screws 12 for installing the column 20. Each screw 12 is threaded with a first adjusting nut 16 located on the upper and lower sides of the support plate 15 for fixing the support plate 15, and a second adjusting nut 17 located on the upper and lower sides of the union seat 13 for fixing the union seat 13. For example, each screw 12 has three first adjusting nuts 16 and three second adjusting nuts 17. The support plate 15 has two first adjusting nuts on the lower side and one first adjusting nut on the upper side. The union seat 13 has two second adjusting nuts 17 on the lower side and one second adjusting nut 17 on the upper side.

[0024] For double-layer automated storage and retrieval systems (AS / RS), the adjustable foot device 10 uses a support plate 15. The first-layer sub-rail 30 is mounted on the support plate 15. The height of the first-layer sub-rail 30 can be adjusted by rotating the first adjusting nut 16 on the screw 12, thus lowering the height of the first-layer sub-rail 30 from the ground. The distance between the two layers of sub-rails 30 can be adjusted not only by the standard pitch of the uprights 20, but also by rotating the second adjusting nut 17 on the screw 12, achieving fine-tuning of the distance between the two layers of sub-rails 30. During adjustment, based on the flatness of the ground, the lowest horizontal height of the first-layer sub-rail 30 is first adjusted. Then, based on the height of the goods on the first-layer sub-rail 30, the lowest height of the second-layer sub-rail 30 is adjusted to compress the height distance between the two layers of sub-rails 30 to the optimal gap, thereby better compressing the overall height of the double-layer AS / RS.

[0025] The adjustable foot device 10 of this utility model can adjust the height of the first layer sub-track 30 and the height of the second layer sub-track 30, making it a double-layer adjustable foot device 10.

[0026] In this utility model, the adjustable foot device 10 has two or four screws 12. When there are two screws 12, the two screws 12 are located diagonally opposite each other on the base plate 11. The first mounting bracket 31 of the first layer sub-track 30 can pass through the two screws 12 and be fixedly connected to the support plate 15.

Figure 3 The diagram shows a setup with two layers of sub-tracks 30. The two sub-tracks 30 of each layer are installed on two columns 20 and are positioned opposite each other. Goods are stored on the two sub-tracks 30 of each layer.

[0029] The bottommost first-layer sub-track 30 is fixedly connected to a number of first mounting brackets 31 that are spaced apart along its length and correspond one-to-one with the support plate 15. The second and above sub-tracks 30 are fixedly connected to a number of second mounting brackets 32 that are spaced apart along their length and fixed to the shuttle beam 40.

[0030] Figure 3 The diagram shows an adjustable foot device 10 consisting of two sets of adjustable foot devices 10, and an upright column 20 consisting of two upright columns 20, each supporting one end of a sub-rail 30. Therefore, a single automated storage and retrieval system (AS / RS) unit includes four adjustable foot devices 10 and four upright columns 20. Correspondingly, each sub-rail 30 has only one first mounting bracket 31 or a second mounting bracket 32 ​​fixed to each end. Each layer of sub-rail 30 has two shuttle beams 40, with the first mounting bracket 31 / second mounting bracket 32 ​​at each end of the sub-rail 30 fixed to the two shuttle beams 40 respectively. In practice, when the sub-rail 30 is long, an adjustable foot device 10 and an upright column 20 can be added in the middle of the sub-rail 30 for support to improve strength.
