DETAILED DESCRIPTION

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] Example 1:

[0055] like Figures 1 to 10 As shown, the first embodiment of the present invention provides a logistics through-type three-dimensional warehouse, including at least one shelf 1 and a track wall 3. According to actual needs, the shelf 1 is provided with multiple horizontally distributed storage layers, each storage layer is divided into multiple columns of cargo locations 2, and each cargo location 2 is given a corresponding number according to its vertical and horizontal position on the shelf 1. A track wall 3 is fixedly installed on one side of the shelf 1, and a plurality of horizontal tracks 4 and a plurality of longitudinal tracks 5 are provided on the track wall 3. The horizontal tracks 4 and the longitudinal tracks 5 are crisscrossed like a chessboard. The intersection of the horizontal track 4 and the longitudinal track 5 forms an intersection node 6.

[0056] The logistics through type stereoscopic warehouse designed in the present application has higher storage and taking capacity compared with the prior art. In the prior art, a sky rail and a ground rail are arranged between the shelves 1, a transversely movable lifting rail is slidably arranged between the sky rail and the ground rail, and a fork mechanism 12 is arranged on the lifting rail. When two or more lifting rails are arranged on the ground rail, the lifting rails will interfere with each other when moving on the ground rail, so that only one lifting rail and one fork mechanism 12 can be arranged beside the shelf 1. This results in that only one fork mechanism 12 can be used for taking and placing goods for the whole row of shelves 1. However, the logistics through type stereoscopic warehouse of the present application creatively designs a rail wall 3. As shown in Figure 2 , two or more stacking machines 7 can be arranged on the rail wall 3, the stacking machines 7 can move along the transverse rails 4 or the longitudinal rails 5, and can change the route at the intersection nodes 6 to switch the transverse rails 4 or the longitudinal rails 5, so that the taking and placing of goods can be simultaneously performed by the stacking machines 7, thereby greatly improving the taking and placing efficiency.

[0057] As shown in Figure 3 and Figure 4 , the stacking machine 7 designed in the first embodiment of the present application comprises a base 8, a transverse moving unit 10 arranged on one side of the base 8 close to the rail wall 3, and a longitudinal moving unit 9, and a fork mechanism 12 is fixedly arranged on the side of the base 8 away from the rail wall 3. The fork mechanism 12 can use the structure in the prior art, which generally comprises telescopic forks and a driving system, one end of the telescopic forks is fixed on the base 8 in the present application, and the other end is telescopic through the driving system. Since the present application does not improve the fork mechanism 12, only the mounting position of the fork mechanism 12 is shown in Figure 3 , and no more description is made in the present application.

[0058] As shown in Figures 4 to 6 , the transverse moving unit 10 designed in the present application has a first working state and a second working state. In the first working state, the transverse moving unit 10 is connected to the transverse rail 4, at this time, the transverse moving unit 10 has the freedom to move along the transverse rail 4, and the stacking machine 7 can move along the transverse rail 4. In the second working state, the transverse moving unit 10 can be disconnected from the transverse rail 4, at this time, the stacking machine 7 can move along the longitudinal rail 5, and the transverse moving unit 10 will not interfere with the transverse rail 4.

[0059] The longitudinal moving unit 9 also has a first working state and a second working state. In the first working state, the longitudinal moving unit 9 can be connected to the longitudinal rail 5, at this time, the longitudinal moving unit 9 has the freedom to move along the longitudinal rail 5, and the stacking machine 7 can move along the longitudinal rail 5. In the second working state, the longitudinal moving unit 9 can be disconnected from the longitudinal rail 5, at this time, the stacking machine 7 can move along the transverse rail 4, and the longitudinal moving unit 9 will not interfere with the longitudinal rail 5.

[0060] The base 8 is provided with a switching unit 11 for switching the operating states of the transverse moving unit 10 and the longitudinal moving unit 9. When the palletizer 7 needs to move along the transverse track 4, the switching unit 11 places the transverse moving unit 10 in the first operating state and the longitudinal moving unit 9 in the second operating state. When the palletizer 7 needs to move along the longitudinal track 5, the switching unit 11 places the longitudinal moving unit 9 in the first operating state and the transverse moving unit 10 in the second operating state.

[0061] Through the above design, the palletizer 7 can move along the transverse track 4 and can be changed to move along the longitudinal track 5 through the switching unit 11 at the intersection node 6, thereby solving the problem in the prior art that multiple palletizers 7 cannot work simultaneously due to path interference when picking up and delivering goods, thereby improving the efficiency of automated picking and delivery in the high-bay warehouse.

[0062] Example 2:

[0063] Based on the first embodiment, the second embodiment of the present invention proposes a more specific design scheme. Figure 4 As shown, in this embodiment, a groove 51 is formed on the inner walls of both the transverse track 4 and the longitudinal track 5. The groove 51 has two guide surfaces 512 arranged in an "eight" shape, and a rack 511 is fixed to the groove 51 between the two guide surfaces 512. The longitudinal movement unit 9 and the transverse movement unit 10 each have two moving modules 91, which can slide in conjunction with the groove 51 and move along the groove 51 through the cooperation of the gear rack 511.

[0064] The structure of the transverse moving unit 10 is basically the same as that of the longitudinal moving unit 9. Due to their different positions, adaptive changes are made in part of the structure.

[0065] Take the longitudinal moving unit 9 as an example. Figures 6 to 10 As shown, the longitudinal movement unit 9 of the present invention includes two movement modules 91. Each movement module 91 includes a base 911. Sliders 912 are designed on both sides of the base 911 and can be retracted toward the base 911. The slides 912 are provided with wedge-shaped surfaces that mate with the guide surfaces 512, and a plurality of rollers 9121 are rotatably mounted on the wedge surfaces. Because the slides 912 can move relative to the base 911, when the switching unit 11 places the movement module 91 into the transverse track 4 or the longitudinal track 5, the two slides 912 move away from each other, and the rollers 9121 are then pressed against the guide surfaces 512 of the sink 51, achieving a sliding fit between the movement module 91 and the sink 51.

[0066] Two gear shafts 913 are rotatably installed on each of the two sliders 912, and a walking gear 914 is installed on each of the gear shafts 913. When the rollers 9121 on the sliders 912 abut against the guide surface 512, the walking gears 914 are engaged with the corresponding toothed strips 511. At this time, only the walking gears 914 need to be driven to rotate, and the moving module 91 can be moved along the sink groove 51.

[0067] The two base bodies 911 on the two moving modules 91 are fixedly connected through the connecting plate 92. The connecting plate 92 is rotatably installed with a linkage shaft 93 through a bearing seat, and the two base bodies 911 are rotatably installed with a transmission shaft 915. The two ends of the linkage shaft 93 are respectively connected to the transmission shaft 915 through two spur gear sets 95. The base body 911 is also rotatably installed with a connecting shaft 916, the middle part of the connecting shaft 916 is connected to the transmission shaft 915 through a second bevel gear set 918, and the two ends of the connecting shaft 916 are respectively connected to the two gear shafts 913 through two first bevel gear sets 917. The driving motor 94 is fixedly installed on the connecting plate 92, and the driving motor 94 is drivingly connected to the linkage shaft 93 through a speed reducer. In this way, when the driving motor 94 drives the linkage shaft 93 to rotate through the speed reducer, the four walking gears 914 on the two moving modules 91 can be simultaneously driven to rotate. It should be noted that the transmission directions of the second bevel gear sets 918 on the two moving modules 91 are opposite, and the final transmission effect needs to meet the following conditions: when the four walking gears 914 are engaged with the corresponding toothed strips 511, the longitudinal moving unit 9 can be driven to move in one direction on the longitudinal rail 5.

[0068] As shown in Figure 7 Since the connecting plate 92 in the transverse moving unit 10 needs to give way to the connecting plate 92 in the longitudinal moving unit 9, the linkage shaft 93 in the transverse moving unit 10 is drivingly connected to the transmission shaft 915 at its two ends through a chain transmission mechanism 96.

[0069] In combination with Figure 6 and Figure 4It can be seen that the switching unit 11 designed in the present invention mainly includes four first guide rods 111 and four second guide rods 112. The first guide rods 111 and the second guide rods 112 are parallel and slidably plugged into the base 8. The ends of the four first guide rods 111 are fixedly connected to the longitudinal movement unit 9, while the ends of the four second guide rods 112 are fixedly connected to the transverse movement unit 10. A first hydraulic cylinder 113 and a second hydraulic cylinder 114 are fixed to the base 8. The first hydraulic cylinder 113 and the second hydraulic cylinder 114 are parallel to the first guide rod 111. The movable ends of the first hydraulic cylinder 113 and the second hydraulic cylinder 114 are fixedly connected to the connecting plate 92 in the longitudinal movement unit 9 and the connecting plate 92 in the transverse movement unit 10, respectively. In this way, by activating the first hydraulic cylinder 113 and the second hydraulic cylinder 114 respectively, the longitudinal movement unit 9 can be controlled to disengage from the longitudinal track 5 or the transverse movement unit 10 can be controlled to disengage from the transverse track 4, thereby achieving the switching of the working states of the longitudinal movement unit 9 and the transverse movement unit 10.

[0070] Example 3:

[0071] like Figures 8 to 10 As shown, based on Example 1 and Example 2, the present invention proposes Example 3. In this embodiment, a telescopic mechanism is designed on the base 911 to control the movement of the slider 912 relative to the base 911, and then cooperates with the switching unit 11 to realize the detachment or docking of the moving unit and the track.

[0072] Take the longitudinal moving unit 9 as an example. A plurality of reset springs 9116 are fixed on the base 911 of the moving module 91 in the longitudinal moving unit 9, and the movable end of the reset spring 9116 is fixedly connected to the slider 912. A slide groove 9112 is provided on the base 911, and a support arm 9111 that slides in cooperation with the slide groove 9112 is fixed on the side of the slider 912 close to the base 911. Under the action of the reset spring 9116, the slider 912 can be dragged toward the base 911, so that the two sliders 912 shrink toward the base 911, thereby disengaging the slider 912 from the sink 51 in the longitudinal track 5. At this time, the switching unit 11 is used to control the longitudinal moving unit 9 to move away from the track wall 3, so that the longitudinal moving unit 9 can be disengaged from the longitudinal track 5.

[0073] When the longitudinal moving unit 9 needs to be docked with the longitudinal rail 5, the switching unit 11 is used to drive the longitudinal moving unit 9 to move into the longitudinal slide rail, so that the sliding blocks 912 are opposite to the sink grooves 51. The third hydraulic cylinder 9117 is fixed in the base 911, and a driving groove communicating with the sliding groove 9112 is formed in the base 911. The driving rod 9113 is slidably installed in the driving groove, and one end of the driving rod 9113 is fixedly connected with the movable end of the third hydraulic cylinder 9117. The third hydraulic cylinder 9117 can control the movement of the driving rod 9113 in the driving groove. The driving slope 9114 is arranged on the driving rod 9113, and the driven slope 9115 is arranged at the end of the supporting arm 9111. When the driving rod 9113 moves and the driving slope 9114 pushes against the driven slope 9115, the supporting arm 9111 can be driven to move away from the driving rod 9113, so that the two sliding blocks 912 can overcome the elasticity of the reset tension spring 9116 and move away from each other, the sliding connection of the two sliding blocks 912 with the two sink grooves 51 is realized, and finally the docking of the longitudinal moving unit 9 with the longitudinal rail 5 is realized.

[0074] As shown in Figure 10 When the driving slope 9114 completely lifts the driven slope 9115, the end of the supporting arm 9111 can be arranged on the driving rod 9113, so as to maintain the state of the two sliding blocks 912 being separated.

[0075] Embodiment four:

[0076] On the basis of the embodiments one to three, the application provides the embodiment four. In the embodiment, the connecting plate 92 in the longitudinal moving unit 9 is fixed with the longitudinal supporting frame 116, and the longitudinal supporting frame 116 is rotatably installed with the supporting wheel 117. The connecting plate 92 of the transverse moving unit 10 is fixed with the transverse supporting frame 115, and the transverse supporting frame 115 is also rotatably installed with the supporting wheel 117. When the longitudinal moving unit 9 is docked with the longitudinal rail 5, the supporting wheel 117 on the longitudinal supporting frame 116 can be arranged on the surface of the rail wall 3, so as to provide a certain supporting force for the base 8.

[0077] Obviously, those skilled in the art can make various modifications and variations to the application without departing from the spirit and scope of the application. Thus, if these modifications and variations of the application belong to the scope of the claims of the application and their equivalent technologies, the application also intends to include these modifications and variations.
