[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] As Figures 1 - 5 , an intelligent access device proposed by the present invention includes an access mechanical rack, a running rack, and a retrieving and transporting roller belt 1;

[0026] The retrieving and transporting roller belt 1 is arranged on the corridor floor between the placement racks in the goods warehouse, and the retrieving and transporting roller belt 1 is at least the height of one goods below the ground surface; so that the access mechanical rack is at a certain height (5 - 10 cm, or slightly higher, because the bottom layer of the shelf is generally 5 - 10 cm higher than the ground) above the ground.

[0027] The running rack includes two rows of support frames symmetrically arranged on both sides of the retrieving and transporting roller belt. The support frames include multiple support legs 20 and support cross beams 2. The support legs 20 are equally spaced and fixed on the side wall of the retrieving and transporting roller belt 1. At the top of the same row of support legs 20, a support cross beam 2 is fixed. A striped toothed belt 22 is arranged inside the support cross beam 2; it slides on the support cross beam 2. Since the bottom of the T-shaped running slide box 3 is heavy, it is not easy to tilt.

[0028] The access mechanical rack includes a T-shaped running sliding box 3, a rotating assembly, a lifting box 5, a lifting plate 6 and an inserting rack structure. The two side boxes of the T-shaped running sliding box 3 are placed on two supporting cross beams 2. The width of the vertical box body of the T-shaped running sliding box 3 is 15-25 mm smaller than the distance between the two supporting cross beams 2. Driving gear discs 32 are installed at the side wall positions on both sides of the vertical box body of the T-shaped running sliding box 3. Part of the driving gear discs 32 protrude from the side wall of the vertical box body of the T-shaped running sliding box 3 to the outside and are engaged with corresponding strip tooth belts 22. The driving gear discs 32 are sleeved on the rotating shafts of driving motors 321, and the driving motors 321 are fixed in the vertical box body of the T-shaped running sliding box 3. A storage battery 9 is arranged in the vertical box body of the T-shaped running sliding box 3. A rotating assembly is arranged at the top of the transverse box body of the T-shaped running sliding box 3. A lifting box 5 is fixed at the top of the rotating assembly. A lifting plate 6 is installed on one side of the lifting box 5. An inserting rack structure capable of lifting is installed on the lifting plate 6. First positioning scanners 30 are installed on the two side walls of the transverse box body of the T-shaped running sliding box 3. Second positioning scanners are embedded near the two side corners at the front side of the lifting plate 6. A controller 10 is arranged in the T-shaped running sliding box 3. The bottom of the inserting rack structure can drop downward on the lifting plate 6 to be close to the upper surface of the fetching and returning roller belt 1 and place the fetched goods on the fetching and returning roller belt 1.

[0029] The lifting box 5 adopts an existing lifting device, which can lift a board and is used in many places, such as forklifts, vehicle repair support platforms, and intelligent warehouse trolleys.

[0030] The driving motor 321 drives the driving gear disc 32 to rotate, and the driving gear disc 32 moves on the strip tooth belt 22, thereby driving the T-shaped running sliding box 3 to move. During the movement, the first positioning scanner 30 continuously identifies the barcodes or QR codes at the bottom position of the shelf. When the position is identified, the lifting box 5 is rotated through the rotating assembly to realize the turning of the inserting rack structure. When loading goods, the goods are lifted to the required height, and the second positioning scanner scans the shelf positions at different heights to push the goods in. The inserting rack structure is inserted into the wooden frame at the bottom of the goods. After loading, the inserting rack structure is withdrawn. The operation for fetching goods is the opposite. The inserting rack structure is inserted into the wooden frame at the bottom of the goods on the shelf, lifted a little and then withdrawn to fetch the goods. Then, the lifting box is turned, and the goods are lowered onto the fetching and returning roller belt 1 and transported away. Multiple goods can be fetched continuously in this way. The purpose of doing this is that goods are generally fetched at regular time intervals, but the storage time is relatively long (within one day, goods can be stored one by one).

[0031] The insertion rack structure includes a U-shaped insertion rack 7, a U-shaped lifting rack 8, a telescopic insertion rod 83 and a telescopic cylinder 831. The U-shaped lifting rack 8 movably penetrates the lifting plate 6 downward. The tails of two said telescopic insertion rods 83 are perpendicularly fixed to the bottom ends of the two vertical frames of the U-shaped lifting rack 8. The two telescopic insertion rods 83 are respectively movably inserted into the tails of the two side racks of the U-shaped insertion rack 7. A telescopic cylinder 831 is installed in the telescopic insertion rod 83, and the end of the cylinder shaft of the telescopic cylinder 831 is fixed at the front position inside the two side racks of the U-shaped insertion rack 7. A lifting assembly for lifting the U-shaped lifting rack 8 is installed on the lifting plate 6.

[0032] When pushing the goods in or taking them out, the U-shaped insertion rack 7 needs to be pushed out, which is pushed out by the telescopic cylinder 831. When putting the goods in, the goods are pushed into the shelf. When taking the goods, the U-shaped insertion rack 7 is inserted into the wooden frame under the goods and then lifted appropriately to take them out.

[0033] The lifting assembly includes a lifting lead screw 82, an inverted L-shaped mounting rod and a servo motor 81. The bottom end of the inverted L-shaped mounting rod is fixed on the lifting plate 6. A servo motor 81 is fixed on the horizontal bar of the inverted L-shaped mounting rod. A lead screw 82 is connected to the rotating shaft of the servo motor 81. The lead screw 82 spirally penetrates through the middle position of the horizontal frame of the U-shaped lifting rack 8. A bearing is sleeved at the bottom end of the lead screw 82 and the bearing is embedded and fixed in the lifting plate 6.

[0034] When it is necessary to place the goods on the pickup return roller belt 1, the U-shaped insertion rack 7 below is needed. The servo motor 81 drives the lifting lead screw 82 to lower the U-shaped lifting rack 8, so that the wooden frame at the bottom of the goods is placed on the pickup return roller belt 1, and then the goods can be transported out.

[0035] Micro-pushing components are provided at the middle positions of the rear halves of the two side racks of the U-shaped insertion rack 7. The micro-pushing components include a connecting rod, a vertical mounting rod 71, a micro-pushing cylinder 712 and a push plate 711. The two ends of the connecting rod are fixedly connected to the inner sides of the two side racks of the U-shaped insertion rack 7. The vertical mounting rod 71 is perpendicularly fixed at the middle position of the connecting rod and is arranged upward. A micro-pushing cylinder 712 is fixed at the top end of the vertical mounting rod 71, and a push plate 711 is fixed on the cylinder shaft of the micro-pushing cylinder 712.

[0036] When rotating, the telescopic insertion rod 83 is outside the shelf. That is to say, the goods may not be completely pushed into the shelf. The micro-pushing cylinder 712 can be used to push a certain distance. When taking the goods, the wooden frame of the U-shaped insertion rack 7 is pulled outwards by 10 - 15, and then inserted inwards continuously, and then lowered. Since the goods do not move downwards, the wooden frame can be placed on the U-shaped insertion rack 7.

[0037] Two lifting lead screws are provided inside the lifting box. The two ends of the lifting lead screws are fixed by bearings. The top end of the lifting lead screw is connected to the rotating shaft of the lifting servo motor. Two inserting plates are fixed on the rear side edge of the lifting plate 6. The inserting plates are movably inserted into the lifting box 5 and are helically sleeved on the lifting lead screws. Vertical strip holes are provided at the front side of the lifting box 5 at the lifting positions of the inserting plates. That is, two inserting plates are synchronously driven by the two lifting lead screws to rise or fall, so as to realize the lifting of the lifting plate.

[0038] The rotating assembly includes a large gear turntable 4, a support cylindrical shaft 41 and a rotating servo motor 401. A support cylindrical shaft 41 is fixed at the center position of the lower surface of the large gear turntable 4. A stable bearing is sleeved on the support cylindrical shaft 41 and the stable bearing is embedded and fixed in the T-shaped running slide box 3. The bottom end of the support cylindrical shaft 41 is semi-circular and is placed on the support semi-circular groove. The rotating servo motor 401 is installed on the top wall of the T-shaped running slide box 3 and a steering gear disc 40 is sleeved on the rotating shaft of the rotating servo motor 401. The steering gear disc 40 meshes with the large gear turntable 401. The rotating servo motor 401 is a braking motor.

[0039] The rotating servo motor 401 drives the steering gear disc 40 to rotate a certain number of turns, so as to drive the large gear turntable 4 to rotate a certain angle (generally 90° or 180°).

[0040] Support strip rails 31 are provided at the bottom of the two side boxes of the T-shaped running slide box 3. Support rollers 311 are equidistantly provided at the bottom of the support strip rails 31. A chute 21 is provided on the upper surface of the support cross beam 2. The support strip rails 31 are inserted into the chute 21. The support rollers 311 are placed on the bottom of the chute 21, and the two side boxes of the T-shaped running slide box 3 do not contact the upper surface of the support cross beam 2. The support rollers 311 are easy to roll and are convenient to push. The support strip rails 31 can be limited in the chute 21 and are not easy to swing.

[0041] One end of the support frame is outside one end of the placement rack in the goods warehouse, and the other end extends to the position of the other end of the placement rack in the goods warehouse. The upper surface of the support cross beam 2 on the support frame is 5 - 10 cm from the ground.

[0042] Set according to the height of the bottom layer of the shelf.

[0043] The two ends of the fetching and transporting roller belt 1 do not correspond to the two ends of the support cross beam 2 and are set at the fetching position as required. The initial inventory position and the shipping position can be not set together, or in two completely different directions.

[0044] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
