Description

Technical Field

[0001] The invention relates to an automatic cigarette package unloading vehicle framing device and a loading and unloading method thereof, belonging to the technical field of cigarette package unloading equipment. Background Art

[0002] There are two types of cigarette packs involved in tobacco redrying plants. One is the post-cured tobacco leaves collected by tobacco leaf purchasing stations in various regions. The tobacco leaf purchasing stations perform preliminary grading and pack the initial cured tobacco packs with hemp slices. The other is the redrying tobacco packs sent to the cigarette production base after the tobacco leaf redrying plant screens, threshes and redryes the tobacco leaves. The existing loading and unloading of cigarette packs usually adopts manual operations, which requires manual unloading of cigarette packs from trucks and stacking them into original tobacco baskets with nets on two sides and openings on the other two sides. Then, the original tobacco baskets are placed on trailers by manual forklifts, and finally moved by trailers to warehouses for storage or transported to production stations. Since the cigarette packs themselves are heavy and the transport trucks are high, generally more than 10 workers are required to operate them, and the handling personnel are easily fatigued. The whole process is time-consuming, labor-intensive and inefficient. In addition, during the unloading and handling process, the cigarette packs are easily trampled and collided, which causes a large secondary crushing of the tobacco raw materials, and there is a problem of low efficiency. At the same time, due to the high loading height of the cigarette pack transport vehicle, it belongs to the category of high-altitude operations, which further affects the loading and unloading vehicle operation due to safety considerations. Summary of the invention

[0010] The aforementioned cigarette package unloading equipment is that the butt ends of the conveyor belt support frames of the second conveyor belt and the third conveyor belt are hinged on the truck chassis, and one end of the conveyor belt support frames of the first conveyor belt and the second conveyor belt are hinged to each other and share a conveyor belt.

[0011] The aforementioned cigarette package unloading equipment further comprises a gantry support, and the other end of the first hydraulic cylinder is connected to a column of the gantry support.

[0012] The aforementioned cigarette package unloading equipment is characterized in that the height of the upper end surface of the gantry support is the same as the height of the lower end surface of the telescopic rotating arm when it is retracted to the lowest point.

[0013] The loading and unloading method using the cigarette packaging and unloading equipment is to set a control device that can be remotely wirelessly operated on the truck chassis, telescopic rotating arm, mechanical arm and multi-section conveyor belt, so that during the loading and unloading process, the cigarette dangerous area can be remotely unmanned to ensure the efficiency and safety of the cigarette loading and unloading process.

[0014] Compared with the prior art, the present invention uses a truck chassis as the base of the cigarette packaging unloading equipment, which has the advantages of easy movement and installation of the equipment. By arranging a telescopic rotating arm, a mechanical arm and a multi-section conveyor belt with adjustable angle on the truck chassis, when unloading or loading, the present invention is parked next to the vehicle to be loaded and unloaded, and the telescopic rotating arm is rotated to above the loading and unloading vehicle. In this way, the mechanical arm moving on the rotating arm can grab or place the goods from the multi-section conveyor belt to complete the loading and unloading of the goods. Because the telescopic rotating arm and the mechanical arm can both achieve angle and height adjustment, and the truck chassis can move forward and backward, it can fully cover the truck compartment. It has the advantages of simple structure, low cost and convenient operation.

[0015] After adopting the present invention, since the loading and unloading personnel do not need to step on the cigarette bales during the whole process, the secondary damage to the tobacco leaves and the mixing of hemp fibers in the cigarette bales can be reduced. At the same time, the operation of the present invention can be remotely controlled, which can avoid the high standard requirements for high-altitude operations and further improve efficiency.

Figure 1 as shown).

[0025] Loading operation: Figure 3 As shown, the cigarette pack unloading equipment (the present invention) is parked on the side of the truck 17, the crossbeam 5 rotates clockwise to a position perpendicular to the parking direction, the telescopic column 19 rises or falls to adjust the crossbeam 5 to a suitable height, the first hydraulic cylinder 10 extends, and one end of the third conveyor belt 11 drops to a suitable position. The cigarette pack 16 is placed on the third conveyor belt 11 from here, transferred via the second conveyor belt 9, and finally reaches the first conveyor belt 4, then the gripper 13 moves to the top of the cigarette pack and opens to grab the cigarette pack, and then moves horizontally along the guide rail 7 to a suitable position above the truck, and then the gripper 13 drops to release the cigarette pack, and this cycle completes the cigarette packing truck operation.

[0026] Unloading operation: When unloading and framing cigarette packs, first adjust the height of the third conveyor belt 11 so that the cigarette frame 18 can be placed at its end. When unloading, the cigarette packs on the truck 17 are grabbed by a gripper and placed on the first conveyor belt 4, and then transferred to the cigarette frame 18.
