Description

Technical Field

[0001] This utility model relates to a loading device, and more particularly to a loading device used in the process of loading tobacco leaves in a tobacco curing barn, for loading tobacco leaves clamped on tobacco clips into the tobacco curing barn. Background Technology

[0002] In the tobacco processing industry, curing barns are needed to process harvested green tobacco leaves, dehydrating them until they turn yellow and dry. During curing, a series of chemical changes occur, altering the flavor of the tobacco. The cured leaves are then shredded to obtain tobacco shreds. The curing barn is equipped with frame-like hanging bars for arranging the tobacco leaves in layers. To improve efficiency, the tobacco leaves are often woven or clipped onto rod-shaped clips. After the tobacco leaves are loaded and hung in the curing barn, the ends of the clips rest on the hanging bars, thus securing the clips with the tobacco leaves hanging naturally.

[0003] Chinese patent document (publication number: CN221489072U) provides a tobacco loading and unloading system for a tobacco curing barn, including a fixed groove on the inner side wall of the horizontal section at the bottom of the curing barn. An automatic loading and unloading mechanism for loading and unloading iron tobacco stalks bound with tobacco leaves is installed within the fixed groove. The automatic loading and unloading mechanism includes a movable platform installed within the fixed groove, a lifting platform installed on the movable platform, and loading and unloading components installed on the lifting platform. This invention enables automatic loading and unloading of iron tobacco stalks bound with tobacco leaves through the automatic loading and unloading mechanism, eliminating the need for frequent device movement and operator entry into the curing barn, making operation simpler and more convenient.

[0004] This loading and unloading system is installed inside the tobacco curing barn. A fixed trough is located at the bottom of the barn, and a loading and unloading mechanism is installed at the trough. The mechanism moves along the length of the trough to accommodate the loading and unloading requirements of tobacco leaves within the depth of the barn. This loading and unloading mechanism remains permanently inside the barn, which not only occupies space but also presents significant challenges due to the harsh environment of the barn during operation. The mechanism is prone to damage, and the lubricating oil or similar grease injected into it can vaporize and contaminate the tobacco leaves. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tobacco leaf loading device for a tobacco curing barn. This loading device can realize automatic loading of tobacco leaves, reduce labor intensity, and the working environment inside the tobacco curing barn will not have a significant impact on the loading device.

[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: a tobacco leaf loading device for a tobacco curing barn, used to load tobacco clips with attached tobacco leaves into the curing barn. The curing barn has several layers of hanging positions, each layer including two parallel and spaced horizontal bars for supporting the two ends of the tobacco clips. The device is characterized by comprising:

[0007] The loading machine is equipped with a support frame for arranging and placing the cigarette clips, and the support frame has gaps;

[0008] The carrier has wheels at the bottom and a load-bearing structure on the upper side. The load-bearing structure is used to support the tobacco clips on the support frame at the gaps on the support frame. In the tobacco curing barn, the lower hanging crossbar is adapted to support the movement of the wheels.

[0009] The elevator is located on the outside of the upper loading machine. The elevator is equipped with a lifting mechanism, which is used to lift the vehicle so that the position of the vehicle matches the different hanging positions. By traveling on the lower hanging crossbar through the wheels, the cigarette clips carried by the load-bearing structure are delivered to the target position of the corresponding upper hanging crossbar.

[0010] A passageway is formed between the loading machine and the elevator, allowing vehicles to move between them.

[0011] The aforementioned traveling wheels are arranged in two rows, with one row resting on a connecting crossbar for movement. When loading tobacco clips containing tobacco leaves into the tobacco curing barn, a supporting structure on the carrier provides support and lift. This supporting structure can be a horizontally positioned rod that abuts against the end of the tobacco clip; alternatively, it can be a thin vertical pole with a receiving interface at its upper end, allowing the pole to pass through the middle of the tobacco leaf. The carrier can be propelled manually or automatically. The tobacco clips can be manually pushed onto the corresponding connecting crossbar, or a lifting mechanism can be installed on the carrier. Driven by the carrier, the tobacco clips move forward on the upper side of the connecting crossbar at the appropriate height. Once in position, the lifting mechanism lowers, and the tobacco clips naturally rest on the connecting crossbar.

[0012] Furthermore, the carrier is equipped with a lifting mechanism, and the supporting structure is mounted on the lifting mechanism. The lifting mechanism is used to raise and lower the supporting structure. By setting up the lifting mechanism, the receiving structure can be lifted or lowered to achieve a high degree of automation and facilitate the loading or lowering of the cigarette clip.

[0013] Furthermore, the supporting structure consists of two horizontally arranged top rods, which are used to support the ends of the cigarette clips. The top rods can be individual rod-shaped structures or formed by U-shaped lifting members. By setting the top rods, the presence of tobacco leaves can be well accommodated, facilitating the loading of the cigarette clips.

[0014] Furthermore, the vehicle is equipped with a battery that provides power to the wheels. By incorporating the battery, the vehicle can achieve automatic power-driven movement, further improving the level of automation, effectively reducing workload, and increasing work efficiency.

[0015] Furthermore, the travel aisle is equipped with segmented guide rails, including fixed rails and movable rails. The fixed rails are located at the loader position, and the movable rails are connected to the lifting mechanism. By using segmented guide rails, the vehicle's position can be easily accommodated when changing positions between the loader and the lifting mechanism. Moreover, the movable rails on the lifting mechanism facilitate positional changes of the vehicle between the connecting crossbar and the lifting mechanism.

[0016] Furthermore, the movable rail extends towards the tobacco curing barn, and its extended end is used to connect with the end of the corresponding connecting crossbar. This eliminates the need for the connecting crossbar to extend outside the tobacco curing barn, and also eliminates the need for additional structures to facilitate the transition of the vehicle between the connecting crossbar and the elevator. This allows the vehicle to smoothly enter the connecting crossbar, simplifying the structure of the loading device.

[0017] Furthermore, a clamping system is provided on the outside of the loading machine. The clamping system, the loading machine, and the elevator are fixed to the traveling frame. A wheeled traveling mechanism is provided on the lower side of the traveling frame. The traveling channel is formed inside the traveling frame, and the fixed rail is fixed to the traveling frame. This makes the loading device structurally compact, functionally integrated, and easy to move, and it can adapt well to loading tobacco leaves into different hanging spaces in the tobacco curing barn.

[0018] Furthermore, the interval between two adjacent hanging positions corresponds to the height of the carrier; two parallel and spaced support rails are provided at the bottom of all hanging positions. The support rails are adapted to support the movement of the wheels, and the interval between the support rails and the hanging crossbars at adjacent hanging positions corresponds to the height of the carrier. No tobacco clips need to be attached to the support rails; the wheels only travel on the support rails when tobacco leaves are loaded onto the bottommost hanging crossbar, thus well meeting actual working requirements and facilitating full loading of tobacco leaves in the curing barn.

[0019] Compared with existing technologies, this utility model has the following advantages: The loader in this loading device can accommodate the parallel loading of multiple tobacco clips, allowing the carrier to transport multiple clips at once during operation. The lifting mechanism accommodates multi-layered hanging positions within the tobacco curing barn, resulting in a high degree of automation. After entering the tobacco curing barn, the carrier uses the hanging crossbars provided inside as support, utilizing the existing conditions of the barn without requiring significant technical modifications to older facilities, thus facilitating the loading of tobacco leaves into ordinary curing barns. This loading device requires minimal manual intervention when loading tobacco leaves into the barn, effectively reducing labor intensity and improving operational efficiency.

[0024] Referring to the accompanying drawings, this tobacco leaf loading device for a tobacco curing barn is used to load tobacco clips 12 with tobacco leaves 9 attached into the tobacco curing barn 7, so that the tobacco clips 12 can be attached to the target attachment position, thereby automatically completing the loading of tobacco leaves 9 into the tobacco curing barn 7.

[0025] The tobacco curing barn 7, as a building, has an interior space for loading tobacco leaves 9. A heating chamber 10 is located on the outside of the tobacco curing barn 7, and the heat generated by the heating chamber 10 is introduced into the tobacco curing barn 7 to cure the tobacco leaves 9 inside. The tobacco curing barn 7 has several layers of hanging positions, where tobacco clips 12 are hung. Each hanging position includes two parallel, spaced-apart hanging crossbars 8, with at least some of the crossbars 8 protruding from the inner wall of the tobacco curing barn 7. Alternatively, the hanging positions can be formed by creating grooves on the side wall of the tobacco curing barn; these grooves act as the hanging crossbars 8. There is a gap between the two hanging crossbars 8, and the tobacco leaves 9 on the tobacco clips 12 hang naturally within this gap, with both ends of the tobacco clips 12 hooked and supported on the two hanging crossbars 8 respectively.

[0026] This mounting device includes a loading machine 2, a carrier 6, and a lift 3. A clamping system 1 is also installed on the outside of the loading machine 2. At this clamping system 1, the tobacco clamps 12 clamp the ends of the tobacco leaves 9, changing the tobacco leaves 9 from a horizontal to a vertical position. The operation at the clamping system 1 can be done manually or mechanically. In mechanized operation, the degree of human involvement is low; only the human hand needs to arrange the green tobacco leaves 9, while the mechanized clamps 12 clamp the tobacco leaves 9. A conversion device then transports the tobacco leaves 9 along with the tobacco clamps 12 towards the loading machine 2. During this transport process, the tobacco leaves 9 change from a horizontal to a vertical position.

[0027] The loading machine 2 is equipped with a support frame, which has gaps on its inside or outside to allow the receiving structure on the carrier 6 to receive the tobacco clips 12 at the gaps. The support frame has horizontally arranged resting positions, on which the tobacco clips 12 with tobacco leaves 9 are placed horizontally. Several tobacco clips 12 are arranged horizontally on the resting positions of the support frame.

[0028] The carrier 6 is used to carry tobacco clips 12 with tobacco leaves 9. The carrier 6 typically carries several tobacco clips 12 at a time, and the number of tobacco clips 12 fully loaded in the aforementioned resting position is the same as the carrying capacity of the carrier 6 at one full load. The carrier 6 has wheels 61 at its bottom and a load-bearing structure on its upper side. The load-bearing structure supports the tobacco clips 12 on the support frame through gaps in the support frame. When the carrier 6 enters the tobacco curing barn 7 to load tobacco leaves 9 onto a certain layer of hanging crossbars 8, the wheels 61 roll forward on the adjacent lower hanging crossbars 8.

[0029] The elevator 3 is located between the upper loading machine 2 and the tobacco curing barn 7. The elevator 3 is equipped with a lifting mechanism, which can be a chain-type lifting mechanism, a lifting cylinder, or a screw mechanism. The lifting mechanism is used to raise and lower the carrier 6 that enters the elevator 3, matching the position of the carrier 6 with the corresponding hanging positions on different layers. This can be achieved by setting sensors and limit switches on the corresponding structure to raise and lower the carrier 6 to the corresponding hanging crossbar 8 position. The traveling wheels 61 on the carrier 6 use the lower hanging crossbar 8 as support, and by moving along the lower hanging crossbar 8, the tobacco clips 12 carried by the supporting structure are delivered to the target position on the corresponding upper hanging crossbar 8.

[0030] A passageway is formed between the loading machine 2 and the elevator 3, allowing the vehicle 6 to move between them. The passageway is set towards the ground, with the height of the loading machine 2 being less than that of the elevator 3. The height of the elevator 3 is adapted to the height of the tobacco curing barn 7, and it must meet the requirements of the loading height of the tobacco leaves 9 on the uppermost horizontal bar 8 inside the tobacco curing barn 7.

[0031] A lifting mechanism is provided on the carrier 6. The lifting mechanism can be a lifting cylinder or a screw mechanism. The supporting structure is set on the lifting mechanism, which is used to raise and lower the supporting structure. When the carrier 6 is in the position of the upper loading machine 2, the lifting mechanism moves the supporting structure upward, causing the supporting structure to lift the tobacco clips 12 on the support frame. Then, the carrier 6 transports the tobacco clips 12 towards the elevator 3. After the carrier 6 transports the tobacco clips 12 to the target position of the target hanging crossbar 8, the lifting mechanism lowers so that the end of the tobacco clips 12 rests on the hanging crossbar 8. After the tobacco clips 12 are placed on the corresponding hanging crossbar 8, the carrier can be used to push the horizontal position of the tobacco clips 12 on the hanging crossbar 8 forward, so that the tobacco clips 12 are close together, thereby increasing the loading capacity of tobacco leaves 9 in the tobacco curing barn 7. The supporting structure consists of two horizontally arranged top rods 62. The top rods 62 are used to receive the ends of the cigarette clip 12, and the tobacco leaf 9 hanging on the cigarette clip 12 is located between the two top rods 62.

[0032] The vehicle 6 is a self-propelled AGV (Automated Guided Vehicle) equipped with a battery that powers the wheels 61. The lifting mechanism is also typically powered by the battery. A lidar sensor can be installed on the vehicle 6 to detect obstacles in its direction of travel. Alternatively, the vehicle 6's movement direction and distance can be programmed. Other sensors can be used to detect the vehicle 6's position.

[0033] The walking passage is equipped with segmented guide rails, including fixed rails 4 and movable rails 5. The fixed rails 4 are located at the loading machine 2, and the movable rails 5 are connected to the lifting mechanism. There are two guide rails, and the interval between the two guide rails is adapted to the interval between the two rows of walking wheels 61 on the carrier 6. The walking wheels 61 move on the two guide rails to realize the position change of the carrier 6 between the loading machine 2 and the lifting machine 3. The end of the movable rail 5 facing the tobacco curing barn 7 extends towards the tobacco curing barn 7. This loading device is located outside the door of the tobacco curing barn 7, and the doorway provides vertical movement space for the extended end of the movable rail 5. Driven by the lifting mechanism, the carrier 6 moves to the corresponding height, and the extended end of the movable rail 5 connects with the end of the corresponding hanging crossbar 8, so that the carrier 6 can move from the movable rail 5 in the lifting machine 3 to the corresponding hanging crossbar 8 to transport the tobacco clips 12 to the upper hanging crossbar 8.

[0034] The clamping system 1, the loading machine 2, and the elevator 3 are fixed to the traveling frame 13, thus connecting these structures into a whole. A wheeled traveling mechanism is provided on the lower side of the traveling frame 13, the traveling channel is formed within the traveling frame 13, and the fixed rail 4 is fixed to the traveling frame 13. The wheeled traveling mechanism uses the ground as support and can move the clamping system 1, the loading machine 2, and the elevator 3 as a whole to adapt to the different hanging spaces within the tobacco curing barn 7.

[0035] The interval between two adjacent hanging positions corresponds to the height of the carrier 6. The carrier 6 uses the lower hanging crossbar 8 as support, and the receiving structure moves the cigarette clip 12 above the adjacent upper hanging crossbar 8. After reaching the target position, the lifting mechanism descends, placing the cigarette clip 12 onto the upper hanging crossbar 8, with both ends of the cigarette clip 12 resting on the two hanging crossbars 8 of the same layer. At the bottom of all hanging positions, there are two parallel and spaced support rails 11. The support rails 11 are adapted to the movement of the traveling wheels 61. The support rails 11 and the hanging crossbars 8 have the same structure, except that the support rails 11 only provide support for the traveling wheels 61. Since the support rails 11 are close to the ground, cigarette clips 12 cannot be hung on the support rails 11. The interval between the support rails 11 and the hanging crossbars 8 at adjacent hanging positions corresponds to the height of the carrier 6. The support rails 11 and all the hanging crossbars 8 are arranged at equal intervals in the vertical direction within the tobacco curing barn 7.
