Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and specifically to an AGV transportation device for a logistics supply chain and its usage method. Background Technique

[0002] AGV is usually also called an AGV cart. It refers to a transport vehicle equipped with automatic navigation devices such as electromagnetic or optical ones, capable of traveling along a specified navigation path, having safety protection and various transfer functions. In industrial applications, it is a forklift truck that does not require a driver, and its power source is a rechargeable battery. Generally, its traveling path and actions can be controlled by a computer, or an electromagnetic track (electromagnetic path-following system) can be used to set up its traveling path. The electromagnetic track is adhered to the floor, and the driverless transport vehicle moves and acts relying on the information brought by the electromagnetic track;

[0003] When an AGV cart transports goods, it generally needs to lift the carrier plate with goods and then move it to achieve the purpose of transportation. Since the existing devices basically rely on the contact area between the carrier plate with goods and the tray to achieve balance and stability during transportation, when transporting and turning with a large amount of goods piled up high on the carrier plate, the piled-up goods are prone to shift in the center of gravity under the action of inertia during turning, and it is easy to have the situation of goods shifting or tilting during turning, affecting the stability during transportation.

[0020] Further, a method for using an AGV transport device in a logistics supply chain. For the AGV transport device in the logistics supply chain, the method includes the following steps:

[0021] S1: Moving the device: When it is necessary to transport goods, start the main body and control the main body to drive the pallet to slide to the bottom of the bearing plate with goods;

[0022] S2: Lifting and raising: Subsequently, the main body controls the pallet to lift at the bottom of the carrier plate. When the pallet is lifted under the control of the main body, it will support the bottom of the carrier plate and lift the carrier plate with the goods.

[0023] S3: Lifting and conveying: Subsequently, the main body conveys the lifted goods with the materials.

[0024] The present invention has the following beneficial effects:

[0025] 1. In the present invention, when the main body controls the pallet to lift at the bottom of the carrier plate, when the pallet is lifted, the top of the square plate of the main body on the pallet will be squeezed by the carrier plate, thereby compressing the spring shaft and moving downward. When the square plate moves downward, it will push the sliding plate to slide through the two push plates on both sides of the square plate. When the sliding plate slides, the limit shaft on the sliding plate will slide obliquely upward in the inclined groove on one of the two right-angled triangular blocks. When the sliding plate slides, it will push the flip plate. After being pushed by the sliding plate, the flip plate will rotate on the multiple rotating telescopic plates. At the same time, when the sliding plate drives the limit shaft to continue sliding, the limit shaft will generate a downward extrusion force on the two spring telescopic rods at the bottom of the flip plate when sliding. At this time, after being squeezed by the limit shaft, the two spring telescopic rods will rotate between the two right-angled triangular blocks through the limit rod and squeeze the flip plate to slide downward on the side walls of the two right-angled triangular blocks when rotating. When the flip plate slides downward, it will drive the right-angled triangular block three to slide downward. When the two right-angled triangular blocks three slide downward, they will squeeze the right-angled triangular block two and, under the reaction of the right-angled triangular block two, pull the rotating telescopic plate to stretch through the movable plate. When the rotating telescopic plate is stretched, it will drive the rotating rod to slide on the side wall of the right-angled triangular block one. When the two sliding plates slide, they will support the bottom of the carrier plate, increasing the contact area between the square plate and the carrier plate. At the same time, when the right-angled triangular block three and the flip plate slide on the side wall of the right-angled triangular block one, they will push the inner wall of the carrier plate and form a multi-point supporting force on the inner wall of the carrier plate. This multi-point support can limit the situation of position deviation when the goods on the carrier plate turn during transportation, enabling the goods to be stably transported when turning, thereby reducing the inclination risk caused by the deviation of the center of gravity distribution due to the position deviation of the goods when turning, and thus improving the stability during transportation.

[0026] 2. In the present invention, when the sliding plate slides on one of the two right-angled triangular blocks, the sliding of the two sliding plates will pull the moving plate to slide inside the rectangular groove towards the bearing plate through the rotating rod. When the moving plate slides, it will drive the two moving plates to squeeze the side wall of the bearing plate. When the lifting plate slides and squeezes the side wall of the bearing plate, the sliding bar will slide in the lifting plate in the opposite direction of the bearing plate under the reaction force when squeezing the bearing plate. When the sliding bar slides, it will drive the two covering plates to move backward synchronously. When the two covering plates slide along with the sliding bar, the semi-circular plate will push the side wall of the covering plate when the sliding bar slides. When the covering plate is pushed by the semi-circular plate, it will form a certain squeezing and covering on the side wall of the bearing plate. At the same time, when the turning plate rotates and slides downward on the side wall of the right-angled triangular block one, it will drive the baffle plate to rotate synchronously and block the connecting plate on the side wall of the connecting plate. Subsequently, when turning to transport goods and the goods drive the bearing plate to tilt and slide due to the inertial force, the tilt of the bearing plate will push the sliding plate two through the connecting plate to make it slide. When the sliding plate two slides, the insertion rods on the two support plates will be guided by the undulating grooves on the sliding plate two to present a front-back movement state. When the support plate slides backward, it will drive the obtuse-angle plate to slide upward at one end inside the through-hole plate through the through-hole plate. At this time, the end of the obtuse-angle plate far from the through-hole plate will drive the lifting plate to slide downward through the sliding guide plate. When the lifting plate slides downward, it will drive the covering mechanism wrapped on the side wall of the bearing plate to pull down the tilted side of the bearing plate. At the same time, the support plate sliding forward will play an upward supporting role on the tilted side of the bearing plate through the covering mechanism to offset part of the inertial force, keep the goods stable, reduce the situation of tipping and falling during the transportation of goods, and improve the transportation efficiency of the goods.

[0027] 3. In the present invention, when the sliding bar squeezes the side wall of the bearing plate, the two semi-circular elastic plates on the sliding bar will deform with both ends expanding outward under the reaction force of the side wall of the bearing plate. When both ends of the two semi-circular elastic plates slide, they will push the auxiliary plate to slide inside the inclined groove. When the auxiliary plate slides, it will be guided by the inclined part inside the inclined groove and then extend outward on the side wall of the covering plate. When the auxiliary plate extends outward, it will slide on the outer walls of both the top and bottom sides of the bearing plate. At the same time, when the two auxiliary plates slide and extend outward, they will drive the tensile elastic rubber plate and slide synchronously in the opposite direction of the side wall of the bearing plate and tightly squeeze and fit the side wall of the bearing plate. Thus, the friction area and friction force between the two covering plates and the side wall of the bearing plate can be increased, and the slippage between the covering plate and the bearing plate caused by pushing or pulling the bearing plate during transportation can be reduced, thereby improving the stability during goods transportation and further reducing the risk of the goods tipping or falling due to slippage.

[0028] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

When the body 1 controls the lifting of the support plate 101 at the bottom of the bearing plate 9, when the support plate 101 is lifted, the top of the square plate 202 of the main body 1 on the support plate 101 will be squeezed by the bearing plate 9, thereby compressing the spring shaft 201 and moving downward.

[0047] The two groups of right-angled triangular blocks 103 are symmetrically distributed with the rectangular groove 102 as the center. Sliding grooves 105 are provided on both the left and right sides of the right-angled triangular block 103. An inclined groove 104 is provided on one side of the right-angled triangular block 103 close to the middle of the rectangular groove 102.

[0050] A flipping mechanism 4 is provided at the top of the first right-angled triangular block 103. The flipping mechanism 4 includes a flipping plate 401 provided at the top of two first right-angled triangular blocks 103. Two spring telescopic rods 402 are rotatably connected to the side of the flipping plate 401 close to the first right-angled triangular block 103.

At the same time, when the sliding plate 301 drives the limiting shaft 302 to continue sliding, the limiting shaft 302 will generate a downward extrusion force on the two spring telescopic rods 402 at the bottom of the flipping plate 401 during sliding.

[0051] The end of the rotating telescopic plate 403 away from the flipping plate 401 is slidably connected to the inside of the sliding groove 105.

The extended end of the sliding bar 701 is rotatably connected with two covering plates 702. The two covering plates 702 are symmetrically distributed with the sliding bar 701 as the center. An inclined groove 703 is formed on the side wall of the covering plate 702. One side of the covering plate 702 close to the lifting plate 603 is rotatably connected with a semi-circular plate 704. One end of the two semi-circular plates 704 away from the covering plate 702 is rotatably connected to the side wall of the lifting plate 603.

When the sliding bar 701 slides, it will drive the two covering plates 702 to move backward synchronously. When the two covering plates 702 slide along with the sliding bar 701, the semi-circular plate 704 will push against the side wall of the covering plate 702 when the sliding bar 701 slides.

[0056] An auxiliary mechanism 8 is arranged on the side wall of the covering plate 702. The auxiliary mechanism 8 includes two semi-circular elastic plates 801 arranged between the two covering plates 702. One end of the two semi-circular elastic plates 801 close to the covering plate 702 penetrates through the side wall of the inclined groove 703 and extends to the inside. The extended ends of the two semi-circular elastic plates 801 are rotatably connected with an auxiliary plate 802. The auxiliary plate 802 is slidably connected inside the inclined groove 703. An elastic rubber plate 803 is rotatably connected between the two auxiliary plates 802. When the two ends of the two semi-circular elastic plates 801 slide, they will push the auxiliary plate 802 to slide inside the inclined groove 703. When the auxiliary plate 802 slides, it will be guided by the inclined part inside the inclined groove 703 and extend outward on the side wall of the covering plate 702.

When the pallet 101 is lifted under the control of the main body 1, it will support the bottom of the carrier plate 9 and lift the carrier plate 9 with goods. Subsequently, the main body 1 transports the lifted goods with materials.

[0062] When the main body 1 controls the pallet 101 to lift under the bottom of the carrier plate 9, when the pallet 101 is lifted, the top of the square plate 202 of the main body 1 on the pallet 101 will be squeezed by the carrier plate 9, thereby compressing the spring shaft 201 and moving downward. When the square plate 202 moves downward, it will push the sliding plate 301 to slide through the two push plates 203 on both sides of the square plate 202. When the sliding plate 301 slides, the limit shaft 302 on the sliding plate 301 will slide obliquely upward in the inclined groove 104 on the two right-angled triangular blocks 103. When the sliding plate 301 slides, it will push the flip plate 401. After being pushed by the sliding plate 301, the flip plate 401 will rotate on the multiple rotating telescopic plates 403. At the same time, when the sliding plate 301 drives the limit shaft 302 to continue sliding, the limit shaft 302 will generate a downward squeezing force on the two spring telescopic rods 402 at the bottom of the flip plate 401 when sliding. At this time, after being squeezed by the limit shaft 302, the two spring telescopic rods 402 will rotate between the two right-angled triangular blocks 103 through the limit rod and squeeze the flip plate 401 to slide downward on the side walls of the two right-angled triangular blocks 103 when rotating. When the flip plate 401 slides downward, it will drive the right-angled triangular block 405 downward. When the two right-angled triangular blocks 405 slide downward, they will squeeze the right-angled triangular block 106 and, under the reaction of the right-angled triangular block 106, pull the rotating telescopic plate 403 to stretch through the movable plate 404. When the rotating telescopic plate 403 is stretched, it will drive the rotating rod 601 to slide on the side wall of the right-angled triangular block 103. When the two sliding plates 301 slide, they will support the bottom of the carrier plate 9, increasing the contact area between the square plate 202 and the carrier plate 9. At the same time, when the right-angled triangular block 405 and the flip plate 401 slide on the side wall of the right-angled triangular block 103, they will push the inner wall of the carrier plate 9 and form a multi-point supporting force on the inner wall of the carrier plate 9. This multi-point support can limit the position offset of the goods on the carrier plate 9 during turning in the transportation process, enabling the goods to be transported stably during turning, thereby reducing the tilting risk caused by the offset of the center of gravity distribution due to the position offset of the goods during turning, and thus improving the stability during transportation.

[0063] When the sliding plate 301 slides on the two right-angled triangular blocks 103, the sliding of the two sliding plates 301 will pull the moving plate 602 to slide inside the rectangular groove 102 towards the bearing plate 9 through the rotating rod 601. When the moving plate 602 slides, it will drive the two moving plates 602 to squeeze the side wall of the bearing plate 9. When the lifting plate 603 slides and squeezes the side wall of the bearing plate 9, the sliding bar 701 will slide in the lifting plate 603 in the opposite direction of the bearing plate 9 due to the reaction force when squeezing the bearing plate 9. When the sliding bar 701 slides, it will drive the two covering plates 702 to move backward synchronously. When the two covering plates 702 slide along with the sliding bar 701, the semi-circular plate 704 will push the side wall of the covering plate 702 when the sliding bar 701 slides. When the covering plate 702 is pushed by the semi-circular plate 704, it will form a certain squeezing and covering on the side wall of the bearing plate 9. At the same time, when the turning plate 401 rotates and slides downward on the side wall of the right-angled triangular block 103, it will drive the baffle 406 to rotate synchronously and block the connecting plate 501 on the side wall of the connecting plate 501. Subsequently, when transporting goods around a turn and the goods drive the bearing plate 9 to tilt and slide due to the inertial force, the tilt of the bearing plate 9 will push the second sliding plate 502 through the connecting plate 501 to make it slide. When the second sliding plate 502 slides, the insertion rods on the two support plates 503 will be guided by the undulating grooves on the second sliding plate 502 to present a front-back movement state. When the support plate 503 slides backward, it will drive the end of the obtuse plate 505 located inside the through-hole plate 504 to slide upward through the through-hole plate 504. At this time, the end of the obtuse plate 505 far from the through-hole plate 504 will drive the lifting plate 603 to slide downward through the sliding guide plate. When the lifting plate 603 slides downward, it will drive the covering mechanism 7 wrapped on the side wall of the bearing plate 9 to pull down the tilted side of the bearing plate 9. At the same time, the support plate 503 sliding forward will play an upward supporting role on the tilted side of the bearing plate 9 through the covering mechanism 7 to offset part of the inertial force, keep the goods stable, reduce the situation of tipping and falling during the transportation of goods, and improve the transportation efficiency of the goods.

[0064] When the slider 701 squeezes the side wall of the bearing plate 9, the two semi-circular elastic plates 801 on the slider 701 will undergo deformation with both ends expanding and sliding outwards due to the reaction force from the side wall of the bearing plate 9. When the two ends of the two semi-circular elastic plates 801 slide, they will push the auxiliary plate 802 to slide inside the inclined groove 703. When the auxiliary plate 802 slides, it will be guided by the inclined part inside the inclined groove 703 and then extend outwards on the side wall of the covering plate 702. When the auxiliary plate 802 extends outwards, it will slide on the outer walls of the top and bottom sides of the bearing plate 9. At the same time, when the two auxiliary plates 802 slide and extend outwards, they will drive the tensile elastic rubber plate 803 and synchronously slide in the opposite direction of the side wall of the bearing plate 9 and tightly squeeze and fit the side wall of the bearing plate 9. Thereby, the friction area and friction force between the two covering plates 702 and the side wall of the bearing plate 9 can be increased, and the slippage between the covering plate 702 and the bearing plate 9 caused by pushing or pulling the bearing plate 9 during transportation can be reduced, so as to improve the stability during cargo transportation and further reduce the risk of the cargo tipping or falling due to slippage.

[0065] It should be noted that: sliding backward means sliding in the direction of the main body 1, and sliding forward means sliding in the direction away from the main body 1.
