[0037] like Figure 1-4 , a storage and retrieval device for a shelf, comprising: a storage and retrieval rack 12, a lifting mechanism 13 and a conveying device 11;

[0039] The conveying device 11 is installed on the storage and retrieval station 10 and the landing gear 131 respectively; the conveying end of the conveying device 11 moves along the horizontal arrangement direction of the storage and retrieval station 10.

[0040] The present solution provides a storage and retrieval device for shelves, which includes a plurality of storage and retrieval stations 10 arranged in height and in horizontal directions, and a lifting mechanism 13 is provided at the end of the storage and retrieval stations 10 arranged in the horizontal direction. The lifting mechanism 13 receives shelves output from a certain height layer, so that the storage and retrieval rack 12 can cooperate with the landing gear 131 to store shelves, and the aligned layers other than the landing gear 131 can be taken out by other shelves. The storage and retrieval rack 12 can synchronously store and retrieve shelves at different height positions, thus solving the problem of low utilization efficiency and low flexibility of the storage and retrieval rack 12 due to the fact that shelves can only be stored or taken out in one direction in the storage and retrieval rack 12.

[0041] The access rack 12 is provided with a plurality of access stations 10 in the height direction, and the access stations 10 are also arranged in the horizontal direction; each access rack 12 is provided with a conveying device 11; the conveying devices 11 of the access stations 10 on the same layer convey the shelves in the same direction, so that the shelves move in the direction of the access port 121 or the direction of the lifting mechanism 13; the access port 121 can expose the conveying device 11 at the end of the arrangement, and the shelf transfer device 16 can place the shelf in the access station 10 from the middle layer to the lower layer through the access port 121, or directly place the shelf in the access station 10 on the top layer; when different shelves need to be accessed at the same time, the landing gear 131 can be pre-lifted to the access station 10 on the layer where the shelf is located, and after the conveying device 11 of the landing gear 131 outputs the shelf to the access station 10 at the height, the shelf is started There are multiple conveying devices 11 on the same layer, and the multiple conveying devices 11 sequentially output the shelves to the direction of the access port 121 to the landing gear 131, thereby realizing the input of the shelves; at the same time, the shelf transfer device 16 takes out other shelves from the shelf concentration point, and then outputs them to the access stations 10 on the remaining layers. Since the lifting mechanism 13 is in a standby state after outputting the shelves, the lifting mechanism 13 can respond to the lifting and alignment with the access station 10 outputting the shelves by the shelf transfer device 16, and the conveying device 11 of the access station 10 on this layer outputs the shelves to the landing gear 131, thereby realizing the output of the shelves; in this way, the access rack 12 can synchronously access the shelves at different heights, which solves the problem that the shelves can only be stored or taken out in one direction in the access rack 12, resulting in low utilization efficiency and low flexibility of the access rack 12.

[0042] Optimally, the conveying device 11 includes: a conveying plate 111, a conveying driving wheel 112, a conveying driven wheel 113, a conveying synchronous belt 114 and a conveying driving assembly 115;

[0043] The conveying plate 111 is installed on the storage and retrieval station 10; the conveying driving wheel 112 and the conveying driven wheel 113 are rotatably installed on the conveying plate 111; the conveying synchronous belt 114 connects the conveying driving wheel 112 and the conveying driven wheel 113 for synchronous rotation; the output end of the conveying drive assembly 115 is connected to the conveying driving wheel 112 for driving the conveying driving wheel 112 to rotate.

[0044] When it is necessary to drive the shelf to move, the conveying drive assembly 115 can be started, and the conveying drive assembly 115 drives the conveying driving wheel 112 to rotate, and under the synchronous action of the conveying synchronous belt 114, drives the conveying driven wheel 113 to rotate, thereby driving a section of the conveying synchronous belt 114 to move in a straight line, driving the conveying synchronous belt 114 and the shelf to move in a straight line, and the shelf can be moved between the lifting mechanism 13 and the access port 121. The number and position of the conveying driven wheel 113 can be set as needed, and is mainly used to open the conveying synchronous belt 114 and perform a driven rotation function.

[0045] Optimally, the conveying plate 111, the conveying driving wheel 112, the conveying driven wheel 113 and the conveying synchronous belt 114 form a storage and retrieval conveying unit 110; a plurality of the storage and retrieval conveying units 110 are installed in the same storage and retrieval station 10;

[0048] The provision of multiple access conveying units 110 allows the conveying synchronous belt 114 to contact the bottom surface of a single shelf, thereby improving the support capacity of the shelf, so that the pressure of the shelf is evenly distributed on the multiple conveying synchronous belts 114, and the stability of the horizontal transmission of the shelf is improved. At the same time, the coaxial rotating shaft 1151 connects the conveying driving wheels 112 of multiple access conveying units 110 in synchronous rotation. The rotation of the coaxial rotating shaft 1151 can drive the multiple conveying driving wheels 112 to rotate synchronously, thereby driving the conveying driven wheel 113 to rotate through the conveying synchronous belt 114, so that the shelf moves in a straight line, realizing the single power source drive of each access station 10, reducing the driving cost of multiple access stations 10, and making the structure of the access device 1 more concise.

[0049] Optimally, the conveying driving wheel 112 and the conveying driven wheel 113 are gears; the conveying synchronous belt 114 is a toothed chain; and the conveying synchronous belt 114 is meshed with the conveying driving wheel 112 and the conveying driven wheel 113 respectively.

At the same time, in order to improve the contact stability of the toothed chain with the shelf, a plate-like object can be set on the lower side of the straight section of the toothed chain, and the plate-like object can be installed on the conveying plate 111, so as to support the straight section of the toothed chain, provide an upward support force for the shelf, and improve the stability of the toothed chain transmission.

[0051] In some embodiments, the access opening 121 may be located on the opposite side of the lifting mechanism 13 from the access rack 12, and the access to the rack occurs between the straight line position of the lifting mechanism 13 and the access opening 121; in some embodiments, the access opening 121 is located on both sides of the access station 10, as follows:

[0054] The support frame 14 is arranged at the access station 10 and is arranged close to the access port 121, while the access port 121 is far away from the lifting mechanism 13, so that the support stability of the goods can be improved when the access device 1 receives or outputs the shelf to the shelf transfer device 16.

[0055] Preferably, the support frame 14 is provided with a positioning plate 142, and the positioning plate 142 is installed on the horizontal support plate 141; the upper end of the positioning plate 142 is higher than the conveying end of the conveying device 11; a plurality of the support frames 14 are installed on the access station 10, and the positioning plates 142 of the plurality of the support frames 14 are arranged along a conveying direction perpendicular to the conveying direction of the conveying device 11, and the access port 121 is located at both ends of the arrangement direction of the positioning plates 142.

[0056] The support frame 14 is provided with a positioning plate 142. The positioning plates 142 of the plurality of support frames 14 are arranged along a conveying direction perpendicular to the conveying device 11. The conveying device 11 at the end position can output the shelf to the positioning plate 142. The positioning plate 142 blocks the shelf from continuing to move, thereby positioning the shelf. The access opening 121 is located at both ends of the arrangement direction of the positioning plates 142, that is, the shelf transfer device 16 can take out the shelf at both ends of the arrangement direction of the positioning plates 142.

[0060] Optimally, it also includes: a weighbridge 15;

[0061] The lifting mechanism 13 is installed on the upper surface of the floor scale 15 .

[0062] The lifting mechanism 13 can serve as the starting point for storing shelves or the end point for taking shelves out; the floor scale 15 can be used to detect the mass of the lifting mechanism 13 when storing or taking shelves out, so as to adjust the configuration corresponding to the mass of the shelf as needed, for example, shelves with heavier weight can be arranged to be stored in a lower position later.

[0063] Optimally, the storage and retrieval rack 12 is provided with two layers of the storage and retrieval stations 10 along the height direction, and two storage and retrieval stations 10 are arranged in sequence along the horizontal direction at the same height.
