[0040] The invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0041] The embodiment of the present invention takes a three-layer warehouse with multiple rows and columns of shelves, and an automated warehouse with only one input and one output port in the middle of each shelf as an example:

[0042] like Figures 1 to 3 As shown, a multi-channel automated warehouse for rapid storage and retrieval includes: a storage section 1, a handling section 2, an entry / exit section 3, and a control section 4; the storage section 1 includes: automated racking 11, longitudinal aisles 12, vertical shafts 13, entry / exit aisles 14, and a storage location mechanism 40.

[0043] The aforementioned three-dimensional rack 11 is a high-density, aisle-type integrated three-dimensional frame. Apart from the rack itself, the upright trusses, longitudinal and transverse load-bearing beams and other supporting components, and the necessary peripheral gaps during the transport of goods, adjacent goods in all columns of the rack are close together. It includes: truss plates 111, longitudinal beams 112, and base bolts 113. According to the requirements of the size of the goods and the number of storage locations, many truss plates 111 and longitudinal beams 112 are vertically connected and combined to form the overall structure of the truss plate 111. The base bolts 113 are installed under each upright of the truss plate 111 to adjust the height of the three-dimensional rack 11 and the overall longitudinal and transverse horizontality.

[0044] The longitudinal aisle 22 is a straight passageway for the longitudinal transport of goods on each floor, with at least one such passageway on each floor. The longitudinal aisles 12 on adjacent floors are staggered and increase in height according to the floor level. Because longitudinal handling equipment is placed in the longitudinal aisle 12, the longitudinal width of the row containing it is greater than the longitudinal width of the original cargo row. It includes longitudinal rails 211 and sliding contact lines 212. The longitudinal rails 211 are typically installed below both sides of the longitudinal aisle 22. The sliding contact lines 212 are installed longitudinally below one of the longitudinal rails 211. The sliding contact lines 212 of the lowest aisle can be installed longitudinally on the ground. This provides a route for the equipment operating within the longitudinal aisle 22. The system is equipped with a power supply. The vertical shaft 13 is located on the same side of the same column of each layer of longitudinal aisle 12, that is, below the upper layer of longitudinal aisle 12. It is a vertical transport channel for the goods of that layer. Since vertical handling equipment is placed in the vertical shaft 13, the horizontal width of the column is greater than the horizontal width of the original cargo position column. The entry and exit aisle 14 is a horizontal transport channel for goods to enter or exit the warehouse. It is located at the bottom of the column where each vertical shaft 13 is located. The number of aisles and their positions in the racking system 11 are determined according to the quantity of goods stored in the warehouse and the required access speed.

[0045] like Figures 4 to 5 As shown, the cargo storage mechanism 40 is a non-powered mechanism for storing goods, horizontally mounted on both sides of each column of cargo compartments in the longitudinal aisle 12 of each floor. It consists of a first drive shaft 41 and a first chain drive 42. The first chain drive 42 includes: a first slot frame 421, a first chain 422, a drive sprocket 423, a driven sprocket group 424, and a connecting mechanism 01. The first slot frame 421 is a long support frame with a C-shaped or rectangular tube cross-section supporting the chain drive. Several longitudinal beams 1 in each column on both sides of each longitudinal aisle 22... At least two first slot frames 421 are vertically installed on the 12th floor. At one end of each first slot frame 421 near the longitudinal aisle 22, a first drive shaft 41 is longitudinally installed. On the first drive shaft 421 located at the same vertical position on the first slot frame 421, each keyway is fitted with a drive sprocket 423. At the other end of each first slot frame 421, a driven sprocket set 424 is installed. A first chain 422 passes over the driven sprockets on each set of straight-line drive sprockets 423 and driven sprocket sets 424, forming a closed-loop, unpowered transverse conveying chain mechanism.

[0046] The connecting mechanism 01 includes: an extension plate 011, a short shaft 012, a first synchronous belt 013, a first synchronous pulley 014, and a gear synchronous combination pulley 015. The specific installation method is as follows: the first synchronous pulley 014 is keyed and installed on the end of the first transmission shaft 41. The extension plate 011, which is vertically installed on one side of the short shaft 012, is installed on the outer end of the first slot frame 421 on the same side. The gear synchronous combination pulley 015 is rotatably mounted on the short shaft 012. The second synchronous belt 73 is mounted on the synchronous pulleys on the first synchronous pulley 014 and the gear synchronous combination pulley 015 to form a synchronous transmission state.

[0047] The stereoscopic shelf form has the advantages that each layer of goods has a non-interfering transportation channel, and the overall frame structure is strong, light in weight, small in size, and low in cost. The non-powered form of the goods location mechanism saves a large number of power components and reduces the corresponding number of electric control accessories.

[0048] As shown in Figures 4 to 5 The conveying part 2 includes a shuttle car 50, a vertical elevator 60, and a transition conveyor 70, which are respectively placed in the longitudinal lane 12, the vertical shaft 13, and the access cross aisle 14,

Two sets of walking passive wheel sets 53 are symmetrically installed at the other end of the trolley frame 51 on both sides, and four wheels are straddled on the longitudinal rails 211 of the longitudinal lane 12 to become a powered trolley that can run along the longitudinal rails 211. The horizontal moving device 54 includes a second transmission shaft 541, a second chain 542, a horizontal motor 543, and a driving sprocket 423. Two second transmission shafts 541 are symmetrically longitudinally installed on both sides of the trolley frame 51, at least two driving sprockets 423 are symmetrically keyed on the shaft middle segments, and a closed-loop second chain 542 is wound on the two driving sprockets 423 in a horizontal line. One end of one of the second transmission shafts 541 is connected with the horizontal motor 543 to form a horizontal chain transmission device. Two sets of synchronization devices 20 are symmetrically installed at the same end of the trolley frame 51,

When the sliding plate 26 moves laterally, the center distance of the two synchronization wheels changes, and the second synchronization belt 24 is automatically adjusted by the tension wheel 22 under the action of the elastic support 23.

[0051] Therefore, the transverse moving device 54 and the synchronization devices 20 on both sides have the beneficial effects of moving the goods into or out of the longitudinal shuttle car 50, and using one transverse power on the shuttle car 50 to drive the displacement of all goods on the same layer.

[0052] The vertical lifting machine 60 is a vertical lifting machine installed in the vertical shaft 13 of each layer, which has the functions of horizontal and vertical transmission of goods. Different layers are configured with vertical lifting machines 60 of different lifting heights, which comprise a lifting door frame 61, a lifting device 62, a lifting hanger 63 and a translation device 64. The lifting door frame 61 is a rectangular plane frame composed of door frame channel steel 611, lower cross beam 612, middle cross beam 613 and upper cross beam 614. Two lifting door frames 61 are erected on the longitudinal sides of the vertical shaft 13, and the plane space is basically overlapped with the plane space of the two sides of the truss piece column 111, and the space stress members on the two sides of the truss piece column 111 are replaced by the lifting door frame 61.

[0053] The lifting hanger 63 is a concave structure frame composed of two vertical end frames 631 and a middle horizontal frame 632, and four groups of channel steel rollers 633 symmetrically installed on both sides of the two vertical frames, which are embedded in the portal channel steel 611 and can roll up and down; the lifting device 62 comprises lifting oil cylinders 621, lifting wheel sets 622 and lifting chains 623, two lifting oil cylinders 621 are vertically placed in the center of the portal channel steel 611 on both sides, the bottom end of the oil cylinder barrel is supported on the lower cross beam 612, the lifting wheel set 622 with two guide wheels is installed at the top end of the piston rod, and two lifting chains 623 pass through the two guide wheels of the lifting wheel set 622, one end is connected to the middle cross beam 613, and the other end is connected to the lower edge of the vertical frame 631, so that the two lifting oil cylinders 621 are supplied with hydraulic oil at the same time, and the lifting hanger 63 vertically rises at a speed twice that of the piston rod rising speed, and the lifting height of the vertical elevator 60 arranged on each layer corresponds to the height of the layer;

[0054] The translation device 64 is a non-powered square frame horizontal transmission device, which comprises a third chain 641, a transmission drum 642 and a linkage mechanism 01, the transmission drum 642 is structured as follows: a certain length of drum section in the middle, a long and short center shaft extending from both ends, after symmetrically keying a driving sprocket 423 on the two end center shafts of the two transmission drums 642, the two driving sprockets 423 are longitudinally installed at the positions of the two longitudinal edges of the middle horizontal frame 632 of the lifting hanger 63, two closed loop third chains 641 pass through the two linear driving sprockets 423 on the transmission drums 642, and form a quadrilateral transmission square frame with the middle drum section of the two transmission drums 642, a set of linkage mechanisms 01 is installed at the long center shaft end of the transmission drum 642 close to the longitudinal tunnel 12, the first synchronous wheel 014 is keyed to the long center shaft end, the extension plate 011 with a vertical short shaft 012 is installed on the outer side of the same end plate of the middle horizontal frame 632 of the lifting hanger 63 by screws, the gear synchronous joint wheel 015 is rotatably sleeved on the short shaft 012 of the cantilever of the extension plate 73, and the second synchronous belt 73 is sleeved on the synchronous wheels of the first synchronous wheel 014 and the gear synchronous joint wheel 015, forming a synchronous transmission state;

[0055] As Figures 6 to 8As shown, the transition conveyor 70 is placed in the bottom layer of the access aisle 14, and has two forms: one, for the transition conveyor 70 placed in the middle of the bottom layer access aisle 14 under the vertical lift 60, generally uses a roller continuous conveyor, the horizontal outer dimension is smaller than the inner cavity horizontal dimension of the middle of the non-powered frame form translation device 64 of the vertical lift 60, the upper plane of the transition conveyor 70 is higher than the moving plane of the translation device 64, and one transition conveyor 70 is placed in the center of each of the vertical lifts 60 under the bottom layer access aisle 14, so that the goods originally on the translation device 64 can be vertically transferred to the transition conveyor 70, and can be horizontally transported to the left or right by the transition conveyor 70, and vice versa, the goods horizontally input to the transition conveyor 70 can be transferred to the translation device 64 of the vertical lift 60, and then vertically lifted into the upper layer aisle, and at the same time, after the translation device 64 is lifted, the transition conveyor 70 still continues to bear the horizontal conveying function of the goods in the access aisle 14, and this form of structure is that at least four adjusting feet 71 are installed below the rack of the transition conveyor 70; the other, for the transition conveyor 70 in the space of the bottom layer longitudinal aisle 12, which is not installed on the ground, and this form is that two pairs of free rollers 72 are installed on the lateral sides of the rack of the transition conveyor 70, and placed in the longitudinal track of the layer, and the return spring 73 is installed on the ground, so that when the bottom layer shuttle 50 runs to the access aisle 14 on the longitudinal two sides, the transition conveyor 70 can be vertically opened when transferring the goods carried by itself, and after the shuttle 50 leaves, the transition conveyor 70 can automatically return to the original position to continue to realize the function of horizontal transfer and conveying of goods in the access part 3;
