Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a storage system, which includes an automatic guided vehicle 10 and a shelf 20. Referring to fig. 2 and 3 together, the shelf 20 includes a frame body 21 and a plurality of first engaging members 22, and the first engaging members 22 are fixedly connected to the frame body 21 and extend in a vertical direction. The shelf body 21 is provided with a plurality of placing holes 23 for placing the goods 201, the placing holes 23 are distributed in a matrix, and each column of placing holes 23 is located between two adjacent first engaging pieces 22. The number of the goods shelves 20 is more than two, any two adjacent goods shelves 20 are oppositely arranged, a channel for automatically guiding the transport vehicle 10 to walk is arranged between every two adjacent goods shelves 20, and the first engaging member 22 is positioned on one side of the frame body 21 close to the channel. As shown in fig. 5, the two racks 20 are spaced apart in the X-axis direction, and the automatic guided vehicle 10 can move between the two racks 20 in the Y-axis direction.

Referring collectively to fig. 4-7, the automated guided vehicle 10 includes a frame 100, a climbing device 200, and a telescoping drive 300. The climbing device 200 includes a telescopic connection member 210, a second engaging member 220 and a climbing driving mechanism 230, wherein the second engaging member 220 and the climbing driving mechanism 230 are both connected to the telescopic connection member 210, and the telescopic connection member 210 can move a predetermined distance along the X-axis direction relative to the frame 100. The number of climbing devices 200 is two, and two climbing devices 200 are spaced apart in the X-axis direction, and for ease of description, one of the climbing devices 200 is designated as a climbing device 200a and the other climbing device 200 is designated as a climbing device 200 b. The telescopic driving means 300 is capable of driving the telescopic links 210a of the climbing devices 200a to move a preset distance in the negative X-axis direction and simultaneously driving the telescopic links 210b of the other climbing device 200b to move a preset distance in the positive X-axis direction, so that the second engagement members 220 of both climbing devices 200 are engaged with the first engagement members 22. The climbing driving mechanism 230 can drive the second engaging member 220 to rotate when the first engaging member 22 is engaged with the second engaging member 220, so that the automatic guided vehicle 10 climbs along the first engaging member 22 to move the cargo 201 to a preset height position.

In this way, the storage system using the automated guided vehicle 10 described above can make full use of the height space. Further, the automated guided vehicles 10 can be arbitrarily moved in the passage between the racks 20, and a plurality of the automated guided vehicles 10 can be simultaneously operated independently of each other, thereby improving the storage and pickup efficiency. Moreover, when one of the automatic guided vehicles 10 fails, the operation of the other automatic guided vehicles 10 is not affected, and the redundancy of the warehousing system can be improved.

Specifically, the telescopic driving device 300 includes a telescopic driving member 310, a driving gear 320, a first rack 330 and a second rack 340. The first rack 330 is fixedly connected to the telescoping connection 210a of the climbing device 200a and the second rack 340 is fixedly connected to the telescoping connection 210b of the climbing device 200 b. The first rack 330 and the second rack 340 are disposed along the X-axis direction, and the first rack 330 and the second rack 340 are disposed at an interval in the Z-axis direction. The driving gear 320 is located between the first rack 330 and the second rack 340, and is engaged with the first rack 330 and the second rack 340.

The automatic guided vehicle 10 moves between two adjacent shelves 20 by the navigation device, when the automatic guided vehicle 10 moves to the position where the second engaging member 220 faces the first engaging member 22, the telescopic driving member 310 drives the first rack 330 to move in the negative X-axis direction, and when the first rack 330 moves, the driving gear 320 engaged with the first rack 330 rotates to drive the second rack 340 engaged with the driving gear 320 to move in the positive X-axis direction. When the first rack 330 and the second rack 340 both move a preset distance, the second engaging members 220 of the two climbing devices 200 respectively engage with the first engaging members 22 of the two opposite racks 20. The climb drive mechanism 230 then drives rotation of the second engagement member 220. Since the first engaging member 22 is fixedly coupled to the frame body 21, the automatic guided vehicle 10 can ascend along the first engaging member 22 while the second engaging member 220 rotates.

In the present embodiment, each set of climbing devices 200 includes two second engagement members 220, and the two second engagement members 220 are spaced apart along the Y-axis direction. The climbing driving mechanism 230 comprises a climbing driving element 231, a driving wheel 232, a driven wheel 233, a synchronous belt 235 and a climbing connecting element 234, wherein the synchronous belt 235 is meshed with the driving wheel 232 and the driven wheel 233, and the driven wheel 233 and the two second meshing elements 220 are connected with the climbing connecting element 234. The climbing driving member 231 can drive the driving wheel 232 to rotate, and the driving wheel 232 drives the driven wheel 233 to rotate through the timing belt 235, so that the climbing connecting member 234 and the two second engaging members 220 fixedly connected with the climbing connecting member 234 rotate.

By adopting the telescopic driving device 300, only one telescopic driving piece 310 is needed to simultaneously drive the second engaging pieces 220 of the two climbing devices 200 to simultaneously extend out in opposite directions, so that the structure and the control program of the automatic guided transport vehicle 10 can be effectively simplified. Of course, in other embodiments, the telescopic driving device 300 may also include two telescopic driving members 310, and the two telescopic driving members 310 respectively drive the second engaging members 220 of the two climbing devices 200 to extend in opposite directions.

In this embodiment, as shown in fig. 3 and 5, the first engaging member 22 is a chain, and the second engaging member 220 is a sprocket. Of course, in other embodiments, the first engaging member 22 may be a rack, and correspondingly, the second engaging member 220 is a gear.

Further, referring primarily to FIG. 5, the climbing device 200 also includes a first guide 240, the first guide 240 being coupled to the telescoping connection 210. The shelf 20 further includes a second guide 24 and a third guide 25, the second guide 24 and the third guide 25 are both connected to the shelf body 21, and the second guide 24 and the third guide 25 are spaced apart from each other along the Y-axis direction. The first guide 240 can contact at least one of the second guide 24 and the third guide 25 when the telescopic link 210 moves to position the automatic guided vehicle 10 such that the second engaging member 220 can engage with the first engaging member 22 when the telescopic link 210 moves a preset distance.

Specifically, the first guide member 240 is a guide wheel, and the guide wheel is rotatably connected to the telescopic link 210. The second guide 24 includes a first connecting section 241 and a first inclined section 242 connected in sequence, and the third guide 25 includes a second connecting section 251 and a second inclined section 252 connected in sequence. The first connecting section 241 and the second connecting section 251 are both fixedly connected to the frame body 21, and a distance between the first inclined section 242 and the second inclined section 252 gradually decreases along a direction from the second engaging member 220 to the first engaging member 22.

When the automated guided vehicle 10 moves to a position where the second engaging member 220 faces the first engaging member 22, the automated guided vehicle 10 stops traveling. Then, the telescopic driving devices 300 drive the telescopic links 210 of the two climbing devices 200 to move in opposite directions, and the first guide 240 is not in contact with the second guide 24 and the third guide 25 during the movement of the telescopic links 210. If the position where the automated guided vehicle 10 stops deviates, for example, the automated guided vehicle 10 is biased in a direction approaching the second guide 24, that is, the automated guided vehicle 10 is shifted in the positive Y-axis direction. At this time, the first guide 240 contacts the first slope section 242 during the movement of the telescopic link 210. Since the distance between the first inclined surface section 242 and the second inclined surface section 252 is gradually reduced along the direction from the second engaging member 220 to the first engaging member 22, the telescopic connection member 210 enables the automatic guided vehicle 10 to move towards the direction close to the third guide member 25 in the moving process, that is, the automatic guided vehicle 10 moves along the negative direction of the Y axis until the second engaging member 220 is opposite to the first engaging member 22, so as to realize secondary positioning, thereby improving the engaging precision of the first engaging member 22 and the second engaging member 220. In addition, when the first engaging member 22 is engaged with the second engaging member 220, the guide wheels of both the climbing devices 200 are abutted against the frame body 21 to restrict the movement of the automatic guided vehicle 10 in the X-axis direction, thereby ensuring that the first engaging member 22 and the second engaging member 220 are always engaged when the automatic guided vehicle 10 climbs along the first engaging member 22.

Further, referring mainly to fig. 6, the automated guided vehicle 10 further includes a traveling device 400, a traveling driving device 500, and a lifting device 600, and the number of the traveling device 400 and the number of the lifting device 600 are two. The walking device 400 comprises a swing arm 410, a walking wheel 420 and a supporting wheel 430, wherein the swing arm 410 is rotatably connected with the frame 100, and the walking wheel 420 is rotatably connected with the swing arm 410. The number of the walking driving devices 500 is two, the two walking driving devices 500 respectively drive the walking wheels 420 of the two walking devices 400 to rotate, and the transportation vehicle 10 can be automatically guided to turn by controlling the rotating speed of the two walking driving devices 500. The supporting wheels 430 are connected with the frame 100, and the lifting device 600 can drive the swing arm 410 to swing when the telescopic connection 210 moves so as to lift the travelling wheels 420. At this time, the automated guided vehicle 10 is supported by the support wheels 430. In this way, the friction of the road wheels 420 with the ground during the secondary positioning of the automated guided vehicle 10 can be reduced.

Specifically, the lifting device 600 is fixedly connected to the telescopic connection member 210, and the lifting device 600 includes a lifting inclined plane 610, and a distance between the lifting inclined plane 610 and the swing arm 410 in the Z-axis direction gradually decreases along a direction in which the telescopic connection member 210 moves. The lifting ramp 610 can abut the swing arm 410 when the telescopic link 210 moves to swing the swing arm 410 upward, thereby separating the road wheel 420 from the ground.

It should be noted that in the present embodiment, the supporting wheels 430 are universal wheels, which can further reduce the resistance of the automatic guided vehicle 10 during the secondary positioning process.

In addition, in this embodiment, as shown in fig. 4 and 6, the walking device 400 further includes a shock absorber 440, one end of the shock absorber 440 is connected to the frame 100, and the other end is connected to the swing arm 410. In this way, it is possible to avoid dropping of the goods 201 on the automatic guided vehicle 10 due to uneven ground or large vibration when the automatic guided vehicle 10 encounters an obstacle.

Further, referring mainly to fig. 6 and 8, in the present embodiment, the automatic guided vehicle 10 further includes a placement device 700, and the placement device 700 includes a power mechanism 710 and a telescopic mechanism 720. The telescopic mechanism 720 includes a fixed slide 721 fixedly connected to the frame 100, a first-stage slide 722 slidably connected to the fixed slide 721, and a second-stage slide 723 slidably connected to the first-stage slide 722. The power mechanism 710 can drive the first-stage slide rail 722 to move relative to the fixed slide rail 721 and drive the second-stage slide rail 723 to move relative to the first-stage slide rail 722, and the first-stage slide rail 722 and the second-stage slide rail 723 have the same movement direction. The goods 201 are placed on the secondary slide rail 723, and the goods 201 move together with the secondary slide rail 723 to place the goods 201 into the placing hole 23 or remove the goods 201 from the placing hole 23.

Specifically, the power mechanism 710 includes a power source 711, a driving synchronizing wheel 712, a driven synchronizing wheel 713, a double-sided timing belt 714, a driving wheel 715, a first transmission member 716, and a second transmission member 717. The double-sided synchronous belt 714 includes a first transmission surface and a second transmission surface, the first transmission surface is engaged with the driving synchronous wheel 712, the driven synchronous wheel 713 and the transmission wheel 715, and the transmission wheel 715 is located between the driving synchronous wheel 712 and the driven synchronous wheel 713 and connected to the primary sliding rail 722 through the first transmission member 716. The second transmission surface is engaged with the second transmission member 717, and the second transmission member 717 is connected to the secondary slide rail 723.

When the driving synchronizing wheel 712 is driven by the power source 711 to rotate, the driving wheel 715 moves between the driving synchronizing wheel 712 and the driven synchronizing wheel 713 due to the engagement of the first transmission surface with the driving wheel 715, and drives the primary sliding rail 722 and the secondary sliding rail 723 to move through the first transmission member 716. Meanwhile, since the second transmission surface is engaged with the second transmission member 717, when the double-sided synchronous belt 714 rotates, the second transmission member 717 is driven to move, so that the secondary slide rail 723 is driven to move relative to the primary slide rail 722. That is, while the first transmission member 716 drives the first-stage sliding rail 722 and the second-stage sliding rail 723 to move, the second transmission member 717 drives the second-stage sliding rail 723 to move along the same direction relative to the first-stage sliding rail 722, so as to increase the moving speed of the second-stage sliding rail 723 and increase the moving stroke of the second-stage sliding rail 723. Also, the direction in which the secondary slide 723 moves may be determined by changing the direction in which the power source 711 drives the driving synchronizing wheel 712 to rotate, so that the telescopic mechanism 720 can be extended in both directions. In this embodiment, as shown in fig. 8, the number of the telescopic mechanisms 720 is two, the two telescopic mechanisms 720 are disposed opposite to each other, the article placing device 700 further includes a linkage member 730, and the linkage member 730 is connected to the primary slide rails 722 of the two telescopic mechanisms 720. By providing two telescoping mechanisms 720, the cargo 201 can be better supported, so that the cargo 201 is more stable when moving along with the secondary slide rail 723. In addition, in the present embodiment, only one power mechanism 710 is required to drive the two telescopic mechanisms 720 to move, so that the structure and control procedure of the automated guided vehicle 10 can be simplified.

Further, the telescopic mechanism 720 further includes a first slide rail connector 740 and a second slide rail connector 750, and the first slide rail connector 740 and the second slide rail connector 750 are both connected to the first-stage slide rails 722 of the two telescopic mechanisms 720. The driving synchronizing wheel 712 and the power source 711 are both connected to the first slide rail connector 740, and the driven synchronizing wheel 713 is connected to the second slide rail connector 750. On one hand, the first slide rail connector 740 and the second slide rail connector 750 are both connected with the first-stage slide rails 722 of the two telescopic mechanisms 720, so that the first-stage slide rails 722 of the two telescopic mechanisms 720 can move synchronously; on the other hand, the driving synchronizing wheel 712 and the power source 711 are connected to the first slide rail connector 740, and the driven synchronizing wheel 713 is connected to the second slide rail connector 750, so that the installation space can be saved.
