Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment, and in particular to a gantry conveyor for connecting AGV tobacco boxes. Background Technology

[0002] In the tobacco re-drying process, some of the tobacco processing steps are moved forward to the re-drying workshop. 200kg / boxes of tobacco are packed and transported to stainless steel boxes, then automatically conveyed to a vacuum re-humidification zone. After re-humidification, the boxes lack auxiliary equipment between the re-humidification machine and the box-turning machine; instead, they are transported by AGV (Automated Guided Vehicle) carts to the conveyor belt at the box-turning machine entrance. After turning, the empty boxes are removed and transported to a temporary storage line. Therefore, it is necessary to solve the turnover problem of the boxes from the AGV carts to the box-turning track, and the empty boxes from the box-turning track back to the AGV carts.

[0003] The re-drying equipment is outdated, with unusual dimensions and considerable weight. Each frame of tobacco leaves weighs 400 kg, and the frame itself weighs approximately 300 kg. Smooth and stable lifting is required to meet the demands of assembly line operations. However, the existing lifting system's connection process is not smooth and stable enough, easily causing the tobacco and empty boxes to shake or tilt. Therefore, a solution is urgently needed to improve the connection stability of the lifting system. Utility Model Content

[0018] The beneficial effects of this utility model are:

[0019] This utility model proposes a gantry conveyor for connecting AGV cigarette boxes, comprising a gantry frame, a first driving component, a first drive shaft, and a first drive sprocket. The first driving component is disposed at the upper end of the gantry frame, and the first drive shaft is rotatably disposed at the upper end of the gantry frame. The first driving component and the first drive shaft are connected by a transmission. Two first drive sprockets are provided, one-to-one corresponding to each other at both ends of the first drive shaft. Two first driven sprockets are rotatably disposed at the lower end of the gantry frame, one-to-one corresponding to each of the two first drive sprockets. A first transmission chain meshes between each corresponding first drive sprocket and first driven sprocket. The gantry conveyor for connecting AGV cigarette boxes also includes a lifting platform, with one drive sprocket on each side. The system should be connected to two first transmission chains. The rotation of the first drive shaft can drive the first transmission chains to move, thereby driving the lifting platform to rise and fall. The lifting platform is equipped with a second drive component, a second drive shaft, and a second drive sprocket. The second drive component and the second drive shaft are connected in a transmission manner. There are two second drive sprockets, which are correspondingly set at both ends of the second drive shaft. The lifting platform is also rotatably equipped with two second driven sprockets, which are correspondingly set at both ends of the second drive sprockets. A second transmission chain is meshed between the corresponding second drive sprockets and second driven sprockets. The second transmission chain is horizontally set and used to transport the cigarette box. The lifting platform has a docking notch for AGV trolleys to enter. The AGV (Automated Guided Vehicle) carries cigarette boxes from the rehumidifier section to the flipping machine section, stopping at the designated stopping point. At this point, the first drive unit activates, rotating the first drive shaft. The first drive sprocket moves the first transmission chain, which in turn raises the lifting platform connected to the first transmission chain. The second transmission chain on the lifting platform carries the cigarette boxes upwards until it is level with the track conveyor at the flipping machine's entrance. Then, the second drive unit rotates, rotating the second drive shaft. The second drive sprocket moves the second transmission chain, transporting the cigarette boxes to the track conveyor. The track conveyor then transports the cigarette boxes to the flipping machine for flipping and other processes. After flipping, the track conveyor returns the cigarette boxes to the second transmission chain. The second drive unit reverses, and the second transmission chain moves the cigarette boxes above the AGV. At this point, the first drive unit reverses, and the first transmission chain lowers the lifting platform until the cigarette boxes are completely carried by the AGV, which then transports the cigarette boxes away. The entire transportation process is relatively smooth. A single first drive component synchronizes the first transmission chains on both sides of the lifting platform, resulting in high stability during the lifting of the cigarette box and minimizing imbalance. Furthermore, a single second drive component synchronizes the two second transmission chains, preventing the cigarette box from rotating when transported to the rail conveyor, thus ensuring high stability. Therefore, the gantry conveyor for AGV cigarette box connection proposed in this invention provides high stability during both lifting and horizontal movement of the cigarette box, improving its reliability.

[0029] This embodiment proposes a gantry conveyor for connecting AGV cigarette boxes, which solves the problem of poor stability of elevator connections in the prior art.

[0030] like Figures 1-2 As shown, a gantry conveyor for connecting AGV cigarette boxes includes a gantry frame 1, a first drive component 2, a first drive shaft 3, and a first drive sprocket 4. The first drive component 2 is located at the upper end of the gantry frame 1, and the first drive shaft 3 is rotatably located at the upper end of the gantry frame 1. The first drive component 2 and the first drive shaft 3 are connected by transmission. There are two first drive sprockets 4, which are correspondingly located at both ends of the first drive shaft 3. Two first driven sprockets 5 are rotatably located at the lower end of the gantry frame 1, and the two first driven sprockets 5 are correspondingly located at both ends of the two first drive sprockets 4. A first transmission chain 6 is meshed between each of the corresponding first drive sprockets 4 and first driven sprockets 5. The gantry conveyor for connecting AGV cigarette boxes also includes a lifting platform 7. The two sides of the lifting platform 7 are correspondingly connected to the two first transmission chains 6. The rotation of the first drive shaft 3 can drive the first transmission chains 6 to move, thereby driving the lifting platform 7 to rise and fall.

[0031] The lifting platform 7 is equipped with a second drive component 8, a second drive shaft 9, and a second drive sprocket 50. The second drive component 8 and the second drive shaft 9 are connected by a transmission. There are two second drive sprockets 50, which are respectively located at both ends of the second drive shaft 9. The lifting platform 7 is also rotatably equipped with two second driven sprockets, which are respectively located at both ends of the second drive sprocket 50. A second transmission chain is meshed between the corresponding second drive sprocket 50 and the second driven sprocket. The second transmission chain is horizontally set and used to transport the smoke box.

[0032] The lifting platform 7 has a docking notch 60, which is used for AGV trolleys to enter.

[0033] Understandably, the AGV trolley carries the cigarette box from the rehumidifier section to the flipping machine section. After arriving at the flipping machine section, it stops at the stopping gap 60. At this time, the first drive component 2 starts, driving the first drive shaft 3 to rotate. The first drive sprocket 4 drives the first transmission chain 6 to move, which in turn drives the lifting platform 7 connected to the first transmission chain 6 to rise. The second transmission chain on the lifting platform 7 carries the cigarette box to rise until the second transmission chain is level with the track conveyor at the entrance of the flipping machine. At this time, the second drive component 8 rotates, driving the second drive component 2 to rotate. The drive shaft 9 rotates, causing the second drive sprocket 50 to rotate and drive the second transmission chain to move, transporting the cigarette box to the rail conveyor. The rail conveyor then transports the cigarette box to the flipping machine for flipping and other processes. After flipping, the rail conveyor returns the cigarette box to the second transmission chain. The second drive component 8 reverses, and the second transmission chain moves the cigarette box above the AGV trolley. At this time, the first drive component 2 reverses, and the first transmission chain 6 drives the lifting platform 7 to descend until the cigarette box is completely carried by the AGV trolley, which then transports the cigarette box away. The entire transportation process is relatively smooth, and the first drive chain 6 on both sides of the lifting platform 7 can be synchronized by a single first drive component 2, resulting in high stability during the lifting of the cigarette box and reducing the likelihood of imbalance. Furthermore, the second drive component 8 can synchronize the movement of two second transmission chains, preventing the cigarette box from rotating when transporting it to the rail conveyor, thus ensuring high stability. Therefore, the gantry conveyor for AGV cigarette box connection proposed in this embodiment provides high stability during both lifting and horizontal movement of the cigarette box, improving its reliability.

[0034] For example, both the first drive component 2 and the second drive component 8 are electric motors. Electric motors are a mature and inexpensive technology, improving the reliability and economy of the gantry conveyor used for AGV cigarette box connection. Of course, the types of the first drive component 2 and the second drive component 8 are not limited to this; they can be flexibly set according to actual conditions, and no further restrictions are imposed here.

[0035] In some optional embodiments, first mounting seats 10 are installed on both sides of the upper end of the gantry frame 1, and the two ends of the first drive shaft 3 are rotatably mounted on the two first mounting seats 10 respectively. This arrangement improves the rotational stability of the first drive shaft 3, thereby improving the reliability of the gantry conveyor used for AGV cigarette box connection.

[0036] In some optional embodiments, a second mounting base is installed on both sides of the lifting platform 7, and the two ends of the second drive shaft 9 are rotatably mounted on the two second mounting bases respectively. This arrangement improves the rotational stability of the second drive shaft 9, thereby improving the reliability of the gantry conveyor used for AGV cigarette box docking.

[0037] In some optional embodiments, auxiliary mounting seats 20 are installed on both sides of the upper end of the gantry frame 1. The two auxiliary mounting seats 20 are arranged one-to-one with the two first mounting seats 10 and are located between the two first mounting seats 10. The auxiliary mounting seats 20 have rotating holes, through which the first drive shaft 3 rotatably passes. This arrangement further improves the rotational stability of the first drive shaft 3, avoids vibration of the first drive shaft 3, and improves the reliability of the gantry conveyor used for AGV cigarette box connection.

[0038] In some alternative embodiments, the first drive sprocket 4 is located between the corresponding auxiliary mounting base 20 and the first mounting base 10. This arrangement improves the rotational stability of the first drive sprocket 4, thereby enhancing the reliability of the gantry conveyor used for AGV cigarette box docking.

[0039] In some optional embodiments, driven mounting assemblies are installed on both sides of the lower end of the gantry frame 1. Each driven mounting assembly includes two driven mounting seats 30 and a rotating rod 40. The rotating rod 40 is rotatably mounted between the two driven mounting seats 30, and a first driven sprocket 5 is mounted on the rotating rod 40. This arrangement improves the rotational stability and installation firmness of the first driven sprocket 5, thereby enhancing the reliability of the gantry conveyor used for AGV cigarette box connection.

[0040] In some optional embodiments, auxiliary mounting components are installed on both sides of the lifting platform 7 away from the second drive member 8. Each auxiliary mounting component includes two auxiliary mounting seats 20 and a rotating shaft, which is rotatably mounted between the two auxiliary mounting seats 20. The second driven sprocket is mounted on the rotating shaft. This arrangement improves the rotational stability and installation firmness of the second driven sprocket, thereby enhancing the reliability of the gantry conveyor used for AGV cigarette box connection.

[0041] In some optional embodiments, a transmission wheel is provided on the first drive shaft 3, and a first power wheel is provided on the drive shaft of the first drive component 2. The first power wheel and the transmission wheel are connected by a belt drive. This arrangement achieves the transmission connection between the first drive component 2 and the first drive shaft 3 through belt drive, which is simple in structure and reliable in operation, improving the reliability of the gantry conveyor used for AGV cigarette box docking.

[0042] In some optional embodiments, a transfer wheel is provided on the second drive shaft 9, and a second power wheel is provided on the transmission shaft of the second drive component 8. The second power wheel and the transfer wheel are connected by belt drive. This arrangement achieves the transmission connection between the second drive component 8 and the second drive shaft 9 through belt drive, which is simple in structure and reliable in operation, improving the reliability of the gantry conveyor used for AGV cigarette box docking.

[0043] In some optional embodiments, guide blocks are provided on both sides of the lifting platform 7, and guide grooves are vertically provided on both sides of the gantry frame 1, with the two guide blocks corresponding to each other in the two guide grooves. This arrangement improves the lifting stability of the lifting platform 7, prevents the lifting platform 7 from shaking, and improves the connection stability of the gantry conveyor used for AGV cigarette box connection.

[0044] For example, the guide block is wheel-shaped, with its wheel edge abutting against the sidewall of the guide groove. This arrangement reduces the friction between the guide block and the guide groove, thereby improving the smoothness of the lifting platform 7.

[0045] In some optional embodiments, the lifting platform 7 includes a base 71 and connecting plates 72 vertically disposed on both sides of the base 71, with the two connecting plates 72 corresponding to two first transmission chains 6. This arrangement improves the stability of the connection between the lifting platform 7 and the first drive sprocket 4 through the connecting plates 72.

[0046] For example, each of the two connecting plates 72 is provided with a connecting block 73, which is located on the side of the connecting plate 72 away from the other connecting plate 72. The two connecting blocks 73 are connected to the two first transmission chains 6 in a one-to-one correspondence. This arrangement avoids interference between the first transmission chains 6 and the base 71, and improves the structural rationality of the gantry conveyor used for AGV cigarette box connection.

[0047] In some alternative embodiments, the base 71 is U-shaped, with a central notch forming a docking notch 60. This arrangement facilitates the installation of the docking notch 60 and also reduces the weight of the lifting platform 7, improving portability.

[0048] In some optional embodiments, a second drive sprocket 50, a second driven sprocket, and a second transmission chain are provided on each of the two parallel sidewalls of the U-shaped base 71. This arrangement allows the cigarette box to move along the length of the two parallel sidewalls of the base 71, facilitating cooperation with the AGV trolley parked at the parking notch 60, and also facilitating contact between the second transmission chain and the edge of the cigarette box, thus improving the structural rationality of the gantry conveyor used for AGV cigarette box connection.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
