Description

Technical Field

[0001] The invention belongs to the technical field of garbage can transmission, and in particular relates to an automatic garbage can transmission system. Background Art

[0002] Trash can, also known as waste bin or trash can, refers to a container for garbage. Most are made of metal or plastic. Trash can is a container for "hiding dirt and filth" in people's lives, and it is also a reflection of social culture. Most trash cans have lids to prevent the odor of garbage from spreading, and some trash cans can be opened with a foot pedal.

[0003] Trash cans are set up in hospitals and other places. Hospital waste treatment is generally centralized, that is, the trash cans are first transported to the garbage cleaning station for centralized treatment. At present, the transportation method of trash cans is usually manual transportation, which requires a lot of manpower and is labor-intensive. On the other hand, since the trash cans in hospitals are usually filled with medical waste, more germs will breed on the trash cans, and manual direct transportation is easy to be infected with these germs, thus causing infection to the staff carrying the trash cans. In addition, the manual transportation route is not fixed, which is easy to cause certain pollution to the surrounding environment.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making any creative work should all fall within the scope of protection of this application.

[0033] like Figure 1 As shown, the automatic garbage can transmission system provided in this specific embodiment includes a garbage can transmission line 30 arranged in the garbage cleaning station, a garbage can transfer device 10 for transferring garbage cans filled with garbage to the garbage can cleaning station or transferring empty garbage cans from the garbage can cleaning station back to the garbage can placement location, a garbage can lifting and transferring device 20 arranged at the garbage can cleaning station for lifting and transferring garbage cans on the garbage can transfer device 10 to the garbage can transmission line 30, and a garbage can transfer and lowering device 50 for transferring empty garbage cans from the garbage can transmission line 30. The garbage can transmission line 30 is provided with a garbage can dumping device 40. After receiving the instruction, the device 10 transfers the trash can filled with garbage to the trash can lifting and transferring device 20. The trash can lifting and transferring device 20 lifts and transfers the trash can to the trash can transmission line 30. The trash can transmission line 30 transfers the trash can to the trash can dumping device 40 to dump the trash in the trash can. After the trash can dumps the trash, it is transferred to the trash can transfer and lowering device 50 along the trash can transmission line 30. The trash can transfer and lowering device 50 transfers the empty trash can to the trash can transfer device 10 on standby at the trash can transfer and lowering device 50. The trash can transfer device 10 transfers the trash can back to the placement location of the trash can to realize automatic transportation of the trash can.

[0034] like Figure 2 As shown, the trash can transfer device 10 includes a rack 200 for placing a trash can 300 and an AGV cart 100 for transferring the rack 200. The AGV cart 100 is provided with a plurality of retractable connecting parts, and the rack 200 is provided with a matching part 250 for matching with the connecting part. The AGV cart 100 can move to the bottom of the rack 200 according to instructions and extend the connecting part to match with the matching part 250 to realize the connection between the AGV cart 100 and the rack 200. After being connected with the rack 200, the AGV cart 100 can drag the rack 200 to a specified position.

[0035] like Figure 3 As shown, the storage rack 200 includes a storage platform 210 for placing a trash can 300, a plurality of legs 220 disposed on the lower end surface of the storage platform 210, and a fence disposed on the upper end surface of the storage platform 210, and a universal wheel 230 is disposed at the lower end of the legs 220. In this specific embodiment, the legs 220 are provided in four numbers and are respectively disposed at the four corners of the storage platform 210, and the universal wheels 230 are disposed on the legs 220 to facilitate the AGV trolley 100 to drag the storage rack 200 to move.

[0036] A plurality of limit members 240 for limiting the position of the trash can 300 are provided on the storage platform 210. As a preferred embodiment of this specific embodiment, there are four limit members 240, and the four limit members 240 are arranged in two rows and two columns on opposite sides of the trash can 300. The trash can 300 is placed between two groups of opposite limit members 240. The setting of the limit members 240 prevents the movement of the trash can 300 on the storage platform 210, and the limit members 240 can ensure that the trash can 300 is always placed in the middle position of the storage platform 210 when placed on the storage platform 210, ensuring that the force on the AGV trolley 100 is balanced when the AGV trolley 100 drags the storage rack 200 to move, which is beneficial for the AGV trolley 100 to transport the trash can 300 along a specific path.

[0037] The limiting member 240 is composed of a U-shaped structure of a horizontal plate, a vertical plate and an inclined plate. The vertical plate is arranged between the horizontal plate and the inclined plate. The horizontal plate is fixedly connected to the storage platform 210. The inclined plate is inclined upward in the direction away from the trash can 300. A first reinforcing plate is arranged between the horizontal plate and the inclined plate. The inclined arrangement of the inclined plate facilitates the placement of the trash can 300. The first reinforcing plate supports the inclined plate to ensure that the structure of the limiting member 240 remains stable and is not easily deformed.

[0038] The fence includes two U-shaped tubes 260 arranged opposite to each other and two connecting tubes 270 for connecting the two U-shaped tubes 260. The U-shaped tubes 260 are arranged upside down on the two ends opposite to the storage platform 210. The end of the U-shaped tube 260 away from the storage platform 210 is inclined toward the storage platform 210. The two U-shaped tubes 260 are located on the two opposite sides of the trash can 300 and these two sides are the same as the two opposite sides of the stopper 240 located on the trash can 300. This arrangement ensures that the position of the trash can 300 is relatively stable and the trash can 300 is easily placed on the storage platform 210. The two ends of the connecting tube 270 are respectively connected to the opposite sides of the two U-shaped tubes 260. The fence surrounds the four sides of the trash can 300, so that the trash can 300 is placed on the storage platform 210 more stably, and the trash can 300 is prevented from tipping over. Especially in the process of transferring the trash can 300, if the trash can 300 tips over and the trash falls on the ground, it not only pollutes the environment but also causes adverse effects.

[0039] In this specific embodiment, Figure 4 As shown, there are two connecting members, which are arranged on opposite sides of the AGV trolley 100, and two matching members 250 are also arranged corresponding to the connecting members. The connecting member includes a retractable pin shaft 120 and a driving assembly for driving the pin shaft 120 to retract. The matching member 250 has a hole for the matching pin shaft 120 to be inserted. The matching member 250 can be a hole directly opened on the storage platform 210 to match the pin shaft 120, or a matching member 250 matching the pin shaft 120 can be separately provided on the storage platform 210. As a preferred embodiment of this specific embodiment, two through holes are provided on the storage platform 210 corresponding to the two connecting members on the AGV trolley 100, and the matching member 250 is a matching connection block provided with a pin hole. The matching member 250 is provided at the through hole, and the pin hole on the matching member 250 is connected with the through hole, and the pin shaft 120 can be extended into or out of the through hole and the pin hole. When the AGV trolley 100 receives the instruction to move to the bottom of the storage platform 210, the driving component drives the pin shaft 120 to extend and insert into the through hole and the pin hole to complete the connection between the AGV trolley 100 and the storage rack 200, and then drags the storage rack 200 to the trash can lifting and transferring device 20. When arriving at the trash can lifting and transferring device 20, the trash can lifting and transferring device 20 operates to lift the trash can and operate it to the trash can transmission line 30. After the trash can is transferred by the trash can lifting and transferring device 20, the AGV trolley 100 carries the storage rack 200 to the trash can transfer and lowering device 50 to receive the empty trash can. After the AGV trolley 100 receives the empty trash can, the driving component drives the pin shaft 120 to extend and insert into the through hole and the pin hole to complete the connection between the AGV trolley 100 and the storage rack 200, and then drags the storage rack 200 to the trash can placement location, and then the AGV trolley 100 releases the connection with the storage rack 200, and then proceeds to the next task.

[0040] like Figure 5 As shown, the driving assembly includes an electric cylinder 130 and a connecting rod 140 connected to the output end of the electric cylinder 130. The connecting rod 140 is an L-shaped structure. One end of the connecting rod 140 is connected to the output end of the electric cylinder 130, and the other end is connected to the pin 120. The electric cylinder 130 and the pin 120 are both located on the upper side of the side where the connecting rod 140 is connected to the electric cylinder 130. This arrangement saves installation space for the driving assembly and can adapt to matching installation with the AGV trolley 100. Furthermore, the AGV trolley 100 is provided with a fixing seat 110 for installing a connecting piece. The fixing seat 110 is a hollow shell. There are two fixing seats 110. The two fixing seats 110 are relatively arranged on both sides of the AGV trolley 100. The electric cylinder 130 is fixedly connected in the fixing seat 110. A sliding sleeve 160 is arranged in the fixing seat 110. The pin 120 is retractably placed in the sliding sleeve 160. The sliding sleeve 160 guides the pin 120 so that the pin 120 can be accurately inserted into the pin hole. The pin 120 is connected to the connecting rod 140 through a fisheye joint 150. The fisheye end of the fisheye joint 150 is hinged to the connecting rod 140. When the AGV trolley 100 drags the storage rack 200 to move, the hinged connection method protects the pin 120, avoids its deformation due to force, and prolongs the service life of the pin 120.

[0041] like Figure 6-8 As shown, the garbage bin lifting and transfer device 20 includes a bracket 600, two lifting and transfer parts 400 that are relatively arranged and synchronously perform a circular circulation, a driving component that drives the lifting and transfer parts 400 to circulate, and a lifting hook 700 that is rotatably arranged on the lifting and transfer parts 400 for hooking the garbage bin 300. The lifting hook 700 hooks the upper edge of the garbage bin 300 during the process of rising with the lifting and transfer parts 400, so that the garbage bin 300 rotates together with the lifting hook 700. The lifting hook 700 lowers the hooked garbage bin 300 during the process of descending with the lifting and transfer parts 400, so as to lift and transfer the garbage bin 300 from the garbage bin transfer device 10 to the garbage bin transmission line 30.

[0042] As a preferred embodiment of this specific embodiment, the lifting and transporting member 400 is in a square shape and circulates. Of course, the lifting and transporting member 400 of the present invention is not limited to being in a square shape and circulates. It can also be in a polygonal shape and circulates, such as a hexagon, an octagon or a circle, as long as it can lift the trash can 300 through the lifting hook 700 on the lifting and transporting member 400 and transfer it to the trash can transmission line 30 as the lifting and transporting member 400 operates. The trash can lifting and transporting device 20 can lift and transport the trash can 300 located at one end of the trash can lifting and transporting device 20 to the other end and put it down. The trash can lifting and transporting device 20 has a relatively small requirement on the height of the position for picking up and putting down the trash can 300, and it also has a low requirement on the height difference between the positions for picking up and putting down the trash can 300. The height difference between the two positions can be less than the vertical height of the lifting and transporting member 400. Therefore, the trash can lifting and transporting device 20 has a wide range of applications and can be used for the transportation of trash cans 300 in different scenarios.

[0043] As a preferred embodiment of this invention, the lifting and transporting member 400 is a chain, and the driving assembly is a sprocket chain transmission drive. The chain driving mechanism has a relatively simple structure, high applicability, stable operation, and low maintenance cost. Of course, the lifting and transporting member 400 is not limited to a chain, and it can also be a linear object with certain strength and flexibility, such as a belt.

[0044] The driving assembly includes a motor 510, a transmission sprocket group 520 connected to the output end of the motor 510, a first transmission shaft 530 connected to the transmission sprocket group 520, a first driven sprocket group 540 and a second driven sprocket group respectively connected to the first transmission shaft 530, and a third sprocket group and a fourth sprocket group respectively connected to the first driven sprocket group 540 and the second driven sprocket group, the first driven sprocket group 540 and the second driven sprocket group are arranged opposite to each other and have the same structure, the third sprocket group and the fourth sprocket group are arranged opposite to each other and have the same structure, two oppositely arranged lifting and transporting components 400 are respectively connected to the third sprocket group and the fourth sprocket group, and the lifting and transporting components 400 realize circular circulation operation through the transmission of the sprocket chain.

[0045] Furthermore, the bracket 600 includes an upper frame and two side brackets 600 relatively arranged at the lower end of the upper frame for supporting the upper frame, and a space for the trash can 300 to pass through is reserved between the two side brackets 600. The side bracket 600 includes two legs and an upper beam 620 and a lower beam 610 connecting the two legs.

[0046] The transmission sprocket group 520 includes a first transmission wheel, a second transmission wheel and a transmission chain for connecting the first transmission wheel and the second transmission wheel. The first transmission wheel is connected to the output end of the motor 510, and the second transmission wheel is connected to the first transmission shaft 530. The motor 510 and the first transmission shaft 530 are both arranged on the upper frame at the upper end of the bracket 600. The two ends of the first transmission shaft 530 are respectively fixedly connected to the upper frame through bearing seats. The first transmission shaft 530 is rotatably arranged on the bearing seat. The transmission sprocket group 520 drives the first transmission shaft 530 to rotate under the drive of the motor 510.

[0047] The first driven sprocket set 540 and the second driven sprocket set are respectively arranged at both ends of the first transmission shaft 530. The first driven sprocket set 540 includes a first driven wheel, a second driven wheel and a driven chain connecting the first driven wheel and the second driven wheel. The first driven wheel is connected to the first transmission shaft 530, and the second driven wheel is connected to the third sprocket set through a second rotating shaft. The second driven sprocket set has the same structure as the first driven sprocket set 540, which will not be described in detail. The rotation of the first transmission shaft 530 drives the first driven sprocket set 540 and the second driven sprocket to rotate, thereby driving the fourth sprocket set and the third sprocket set to operate.

[0048] The fourth sprocket group and the third sprocket group are respectively arranged on the two opposite side surfaces of the bracket 600, that is, the fourth sprocket group and the third sprocket group are respectively arranged on the two side brackets 600, and a space for the operation of the trash can 300 is reserved between the fourth sprocket group and the third sprocket group. The fourth sprocket group and the third sprocket group have the same structure, and the third sprocket group is taken as an example for introduction. The third sprocket group includes a plurality of sprockets 550. In this specific embodiment, the third sprocket group includes 4 sprockets 550. The lifting and transporting member 400 sequentially passes around the 4 sprockets 550 to form a square structure. The 4 sprockets 550 are rotatably connected to the bracket 600 through a rotating shaft. The second driven wheel is connected to the rotating shaft of one of the sprockets 550. The operation of the third sprocket group drives the lifting and transporting member 400 to circulate.

[0049] A limiting support member is provided on the lower cross beam 610 for installing one side of the third sprocket group, and the limiting support member includes a support frame 630 connected to the lower cross beam 610, a plurality of support blocks 640 connected to the support frame 630, a connecting plate 650 provided on the plurality of support blocks 640, and a limiting guide member 660 provided on both ends of the connecting plate 650. Two of the sprockets 550 of the third sprocket group are rotatably connected to the upper cross beam 620 via a rotating shaft, a bearing seat is provided on the upper cross beam 620, and the rotating shaft is rotatably installed in the bearing seat, and the other two sprockets 550 are rotatably connected to the two support blocks 640 located at both ends of the support frame 630 via rotating shafts. One end of the limiting guide member 660 is connected to the connecting plate 650, and the other end is provided on the inner side of the lifting and transporting member 400 in the vertical direction and is provided along the running direction of the lifting and transporting member 400.

[0050] The lifting hook 700 includes an L-shaped plate composed of a horizontal plate 710 and a vertical plate 720, and a hook plate 730 disposed on one end of the horizontal plate 710 away from the vertical plate 720. A second reinforcing plate 740 is disposed between the vertical plate 720 and the horizontal plate 710, and a space for placing the upper edge of the trash can 300 is reserved between the second reinforcing plate 740 and the hook plate 730. The vertical plate 720 is connected to the lifting and transporting member 400 through a connecting shaft 750, and the connecting shaft 750 is fixedly connected to the lifting and transporting member 400, and the vertical plate 720 is rotatably connected to the connecting shaft 750. Furthermore, a fixing block is disposed at one end of the connecting shaft 750 connected to the lifting and transporting member 400, and the connecting shaft 750 is fixedly connected to the fixing block and the lifting and transporting member 400, so as to enhance the connection stability and protect the lifting and transporting member 400. The lifting hook 700 is rotatably connected to the lifting and transporting member 400 so that the lower end of the lifting hook 700 is always located at the lower end and will not change with the operation of the lifting and transporting member 400. This setting ensures that after the extraction hook hooks the trash can 300, the extraction hook can always stably hook the trash can 300.

[0051] The structure of the garbage bin transfer and lowering device 50 is the same as that of the garbage bin lifting and transferring device 20 , and the running direction of the lifting and transferring parts of the garbage bin transfer and lowering device 50 is opposite to the running direction of the lifting and transferring parts of the garbage bin lifting and transferring device 20 .

[0052] Furthermore, the trash can transmission line 30 can be in the form of common belt transmission, chain transmission, chain plate transmission, roller transmission, etc., and the trash can dumping device 40 can be Fig. 9 A conventional garbage bin dumping device 40 is shown on a garbage truck 60 .

[0053] The automatic transfer system for trash cans can be applied to places such as hospitals to achieve full automation of trash treatment in places such as hospitals that have high requirements for hygiene. When the automatic transfer system for trash cans is in use, one AGV trolley 100 corresponds to multiple racks 200. After the trash cans 300 are placed on the racks 200, they are placed together with the racks 200 in the place where the trash cans 300 need to be placed. The AGV trolley is connected to the hospital's control system for communication. The hospital's control system issues control instructions, which can centrally process the trash cans on a regular basis. The control system issues instructions to the AGV trolley to transport the trash cans of various departments of the hospital. The AGV trolley 100 moves to the corresponding rack 200 according to the instructions issued by the control system and passes through the connector. The AGV trolley 100 is connected to the matching piece 250 to realize the connection between the AGV trolley 100 and the rack 200. After being connected to the rack 200, the AGV trolley 100 drags the rack 200 to move to the trash can lifting and transferring device 20. The trash can lifting and transferring device 20 is provided with a detection device. When the detection device detects the transferred trash can, the trash can lifting and transferring device 20 operates the lifting hook 700 on the lifting and transferring part 400 to operate with the lifting and transferring part 400. When the lifting hook 700 rises in the vertical direction, the lifting hook 700 passes through the upper edge of the trash can 300 and hooks The upper edge of the trash can 300 is held, and then the trash can 300 is lifted and pulled, so that the trash can 300 is lifted in the vertical direction under the action of the lifting and transporting member 400, and then transported to the top of the trash can transmission line 30 in the horizontal direction, and then descends to the trash can transmission line 30 as the lifting and transporting member 400 descends in the vertical direction. The lifting hook 700 continues to descend in the vertical direction as the lifting and transporting member 400 separates the lifting hook 700 from the trash can 300. After the trash can 300 is placed on the trash can transmission line 30, the trash can transmission line 30 moves forward for a distance. The garbage can is placed in a space provided for the next garbage can. When the garbage can is transferred to the garbage dumping area by the garbage can transmission line 30, the garbage collection device dumps the garbage in the garbage can and then puts the garbage can back to the garbage can transmission line 30. After the garbage can is put back to the garbage can transmission line 30, the garbage can is transferred to the garbage can transfer and lowering device 50 by the garbage can transmission line 30. The garbage can transfer and lowering device 50 transfers and lowers the garbage can to the garbage can transfer device 10 that has been moved to the garbage can transfer and lowering device 50. The garbage can transfer device 10 sends the garbage can back to the place where the garbage can is placed. After the garbage can on the garbage can transfer device 10 is transferred away by the garbage can lifting and transferring device 20, the garbage can transfer device 10 moves to the garbage can transfer and lowering device 50 and waits.
