Description

Technical Field

[0001] The invention relates to the field of manipulators, and in particular to a holding and dragging manipulator for airport luggage handling. Background Art

[0002] With the development of tourism, the number of luggage bags flowing in airports in a single day is very large. At present, most of the luggage handling at airports is done manually. Passenger luggage is transported to the handling warehouse through a conveyor belt and loaded onto trucks. However, with the gradual development of science and technology, manipulators are gradually applied to the handling of luggage bags to reduce the burden of manual handling. For example, a multifunctional luggage grabbing and folding manipulator with application number CN202110597921.0 in the prior art is a transport lifting mode that uses a suction cup and a bag grabbing mechanism. However, the suction cup is only suitable for some hard materials with flat surfaces. As for suitcases, this system is not suitable for leather or fabric luggage because the fabric has pores and is not suitable for suction by suction cups, which may cause the luggage to fall. As for grabbing suitcases, hard metal or plastic suitcases may have scratches on their surface when they are clamped by the robot, which may cause trouble to passengers. As for luggage bags, some bags may contain electrical appliances or musical instruments, which are fragile items. For luggage bags that are not full, the robot needs a larger stroke and force to pick up the luggage, which may cause damage to the fragile items inside the luggage bags and bring unnecessary losses to passengers.

[0035] Method of use of the present invention:

[0036] In the initial state: the user is required to control the present invention to enter between the shipping vehicle and the conveyor belt, and make the side of the present invention provided with the rotating plate 21 face the direction of the conveyor belt, and make the rotating plate 21 be located directly above the conveyor belt, the push plate 26 is on the side of the No. 1 slide rail 35 farthest from the lifting plate 38, the electric push rod 32 is in a fully extended state, the No. 1 slider 23 and the No. 2 slider 22 are on the No. 2 slide rail 36 and the No. 3 slide rail 37 on the side farthest from the No. 1 motor 28 and the No. 2 motor 29, the No. 2 air groove 44 is in contact with the top end of the No. 3 screw rod 46, and the limit plate 30 is located on the side close to the No. 2 motor 29, as shown in FIG. Figure 1 shown.

[0037] When the present invention is needed, the user only needs to start the present invention. After the present invention is started, the camera 34 will remain in the started state to monitor the conveyor belt. When a suitcase passes under it, it will be detected, so that the control terminal 27 drives the second robot arm 14 and the first robot arm 15 to cooperate with each other, thereby driving the rotating plate 21 to move. After the second robot arm 14 and the first robot arm 15 move, the push plate 26 will be parallel to the long side of the detected suitcase, and Under the action of the control terminal 27, the electric slider is driven to slide on the first slide rail 35 toward the lifting plate 38, thereby pushing the luggage. When the luggage is in a good position, during the movement of the push plate 26, the lifting surface of the lifting plate 38 should be on the same horizontal plane as the top surface of the conveyor belt, and as the push plate 26 moves, the luggage is pushed onto the lifting plate 38. If the luggage is in a bad position, the control terminal 27 will drive the electric push rod 32 to retract, thereby driving the connecting plate The first distance sensor 40 detects that the luggage is in contact with the lifting plate 38, and at this time, the control terminal 27 temporarily stops the push plate 26 from moving further, and at the same time, drives the motor in the connecting block 20 to drive the rotating plate 21 to rotate, so that the direction of the rotating plate 21 returns to the initial state. At this time, the first machine The robot arm 15 and the second robot arm 14 will continue to move until the bottom surface of the lifting plate 38 is out of the range of the conveyor belt. At this time, it should be recognized by the camera 34, so that the control terminal 27 drives the electric push rod 32 to reset, so that the connecting plate 33 moves downward, so that the top surface of the lifting plate 38 is again on the same horizontal plane with the bottom surface of the conveyor belt. At this time, the electric slider on the push plate 26 will be started again under the action of the control terminal 27, so as to push the suitcase onto the lifting plate 38.

[0038] As the push plate 26 continues to push until the luggage is detected by the No. 2 distance sensor 41, and when the No. 2 distance sensor 41 detects the luggage, the auxiliary suction cup 42 has been compressed, and the No. 2 distance sensor 41 will transmit a signal to the control terminal 27, and the control terminal 27 will drive the No. 1 air pump 53 to start, thereby pumping air into the No. 1 air groove 31, so that the auxiliary suction cup 42 can adsorb the surface of the luggage. If the material is a breathable material, it cannot be adsorbed. At the same time, the control terminal 27 will stop the push plate 26 from continuing to move. At this time, the control terminal 27 will drive the No. 3 motor 51 to start. After the No. 3 motor 51 is started, its motor shaft will The third screw 46 will be driven to rotate, thereby driving the second air groove 44 to descend, thereby driving the main suction cup 52 to descend, and the depth of the descent of the main suction cup 52 is determined by the camera 34, until the main suction cup 52 is attached to and compressed with the luggage, the continued driving of the third motor 51 will be stopped, and at the same time the control terminal 27 will drive the second air pump 48 to start, thereby exhausting air in the second air groove 44, so that the main suction cup 52 can adsorb the surface of the luggage. If the material cannot be adsorbed, the main suction cup 52 will also provide a certain pressure to maintain the stability of the luggage during transportation. After the luggage is lifted, the fifth motor 18 will drive the luggage under the action of the control terminal 27. The fixed platform 19 rotates, so that it is convenient for the second robot arm 14 and the first robot arm 15 to place the luggage inside the consignment vehicle with the lifting mechanism 61. When the lifting mechanism 61 is to unload the luggage, the motor in the connecting block 20 will be started under the action of the control terminal 27, and first rotate ninety degrees, so that the long side of the rotating plate 21 is parallel to the long side of the consignment vehicle. At the same time, under the cooperation of the first robot arm 15 and the second robot arm 14, the bottom surface of the lifting plate 38 is in contact with the top surface of the consignment vehicle (if stacked, it is in contact with the luggage below), and the limit plate 30 will face the direction of the conveyor belt. At this time, under the drive of the control terminal 27, the first air pump 5 3 will stop operating, so that the auxiliary suction cup 42 stops adsorbing the luggage, and at the same time controls the limit plate 30 to move in the direction away from the conveyor belt until the third distance sensor 49 detects the luggage, and at the same time the third distance sensor 49 detects the luggage, the limit plate 30 is in contact with the luggage, so that the limit plate 30 stops moving under the action of the control terminal 27. At this time, the first motor 28 and the second motor 29 will be started under the action of the control terminal 27, so as to drive the first slider 23 and the second slider 22 to move in the direction of the conveyor belt, and due to the suction or pressure of the main suction cup 52, the luggage can be out of the range of the lifting plate 38, but will not move.Thus, the luggage is unloaded. After the luggage is unloaded, the second mechanical arm 14, the first mechanical arm 15 and the rotating plate 21 will be reset at the control terminal 27 and return to the initial state. At the same time, the second motor 29 and the first motor 28 are also reset during the reset process of the other components. Before being used again, the present invention will be restored to the initial state, which is convenient for subsequent use. In this way, the luggage is transported back and forth.
