[0023] See also Figure 1 In this embodiment, a liftable cigarette package transfer vehicle specifically includes a vehicle body 1, a lifting mechanism 2, a transfer platform 3, wheels 4 and a driving motor 5.

[0024] The fixed end of the lifting mechanism 2 is installed on the vehicle body 1, which is specifically a rectangular structure, and the driving end of the lifting mechanism 2 is connected to the transfer platform 3, so that the height of the transfer platform 3 can be adjusted through the lifting mechanism 2, so that the transfer platform 3 can be adjusted to a suitable height according to actual needs, which is convenient for the rapid movement of cigarette packages.

Of course, this is only a preferred solution of the utility model. Those skilled in the art can also select other types of lifting mechanisms 2 according to actual needs in other embodiments of the utility model.

[0026] In combination with the actual application environment of this embodiment, the vehicle body 1 needs to meet the following conditions when being specifically selected: 1. Affordable price; 2. High strength; 3. Easy to weld. Through comprehensive analysis of existing vehicle body 1 materials (such as stainless steel profiles, aluminum profiles, and machine-made rectangular steels, etc.), in this embodiment, the material of the vehicle body 1 is machine-made rectangular steel, and a plurality of machine-made rectangular steels of different lengths are welded to obtain the desired body.

[0027] The wheels 4 specifically include two straight front wheels 41 and two steering rear wheels 42. The two straight front wheels 41 are respectively installed on both sides of the front end of the vehicle body 1, and the drive motor 5 is installed on the lower side of the vehicle body 1 and located at the straight front wheels 41. Its output end is respectively connected to the two straight front wheels 41, so that the two straight front wheels 41 can be driven to rotate, thereby driving the entire transfer vehicle to move. The two steering rear wheels 42 are respectively installed on both sides of the rear end of the vehicle body 1, and a control handle 7 is provided at the rear end of the vehicle body 1, so that it is convenient to manually drive the control handle 7 to adjust the driving direction of the transfer vehicle through the steering rear wheels 42.

[0028] Combined with the actual application environment of this embodiment, the wheels 4 need to meet the following conditions when they are specifically selected: 1. Load-bearing ≥ 1t; 2. Safe and reliable; 3. Strong front wheel stability and grip; Strong rear wheel steering flexibility; Through comprehensive analysis of existing wheels 4 (such as rubber-plastic solid tires, rubber-plastic hollow tires and nylon wheels), in this embodiment, the straight-moving front wheel 41 adopts a rubber-plastic solid wheel, and the steering rear wheel 42 adopts a nylon wheel. Of course, this is only a preferred solution of the utility model, and those skilled in the art can also select other types of wheels 4 according to actual needs in other embodiments of the utility model.

[0029] In combination with the actual application environment of this embodiment, the drive motor 5 needs to meet the following conditions when being specifically selected: 1. Low price; 2. Convenient charging; 3. Safe and reliable. Through a comprehensive analysis of existing motors (such as servo motors, ordinary motors and special motors), in this embodiment, the drive motor 5 is specifically selected as a special motor.

[0030] The transfer platform 3 specifically includes a transfer frame 31 , a plurality of transfer rollers 32 and two groups of guide rollers 33 .

[0031] Combined with the actual application environment of this embodiment, the transfer roller 32 and the two sets of guide rollers 33 need to meet the following conditions when they are specifically selected: 1. The cost is less than 1,000 yuan; 2. The difficulty of pulling the cigarette pack; 3. High stability; 4. Short operation time. Through a comprehensive analysis of existing rollers (such as stainless steel rollers and rubber-coated rollers, etc.), in this embodiment, the transfer roller 32 and the guide roller 33 are both self-rotating stainless steel rollers - rolling bearings are provided at both ends, and the fixed end of the rolling bearing is installed on the mounting plate 34 or the transfer frame 31 to achieve the installation of the transfer roller 32 or the guide roller 33. Of course, this is only a preferred solution of the utility model. Those skilled in the art can also choose other types of rollers according to actual needs in other embodiments of the utility model.

[0032] Among them, the lower side of the transfer frame 31 is connected to the driving end of the lifting mechanism 2; the transfer rollers 32 are installed side by side on the upper side of the transfer frame 31 along the width direction of the transfer frame 31, and a gap is arranged between two adjacent transfer rollers 32 along the width direction of the transfer frame 31, and the axial direction of each transfer roller 32 is arranged along the length direction of the transfer frame 31; two groups of guide rollers 33 are respectively installed on the two side walls in the length direction of the transfer frame 31, and are arranged parallel to the transfer rollers 32, and the horizontal plane where the axis thereof is located is lower than the horizontal plane where the axis of the transfer roller 32 is located, so that when transporting cigarette packages, the guide rollers 33 can be located at the lower side of the cigarette packages, and the cigarette packages can be pulled along the direction from the guide rollers 33 to the transfer rollers 32 by manual force, so that the cigarette packages can be moved very quickly, thereby eliminating the need for manpower to lift the height of the cigarette packages, reducing the work intensity of workers, and improving the transfer speed.

[0033] Friction calculation: f (friction) = μ (friction coefficient) * N (normal pressure);

[0034] During the existing cigarette package transportation process, N (positive pressure) is equal to the cigarette package gravity 490N.

[0035] The surface of the sorting table is painted. According to the information, the friction coefficient of the paint surface is 0.05.

[0036] Paint surface of transfer vehicle f (friction force) = μ (friction coefficient) * N (normal pressure) = 0.05 * 490N = 24.5N;

[0037] Therefore, the f (friction force) of the paint surface of the transfer vehicle is 24.5N.

[0038] After the transfer vehicle was installed, a single-pack isolation experiment was conducted in the sorting workshop. The transfer vehicle was loaded with cigarette packs (50kg / pack) and raised to a height of 80cm on the sorting table. The transfer roller 32 was used to push the pack onto the sorting table. The required thrust is equal to the friction force generated when the cigarette pack is pushed from the roller surface of the transfer vehicle to the sorting table surface (painted surface). The calculation process is as follows:

[0039] According to the data, the friction coefficient of the paint surface is μ = 0.05, and the friction coefficient of the rolling bearing is μ = 0.004. When the cigarette pack is pushed from the roller surface of the transfer vehicle to the sorting table (paint surface), the friction force is the average friction force of the roller surface and the paint surface.

[0040] f1 (roller surface friction) = μ1 (friction coefficient) * N (normal pressure) = 0.004 * 490N = 1.96N;

[0041] f2 (friction force on the paint surface) = μ2 (friction coefficient) * N (normal pressure) = 0.05 * 490 N = 24.5 N;

[0042] f = (f1 (roller surface friction) + f2 (paint surface friction)) ÷ 2 = 13.23N;

[0043] N (thrust used by a 50kg cigarette pack) = f (average friction force of a 50kg cigarette pack on the roller surface and the painted surface) = 13.23N.

[0044] From the above calculation results, it can be seen that the labor intensity of cigarette package transportation is greatly reduced, which is significantly better than the set target value of 24.5N.

[0045] Specifically, in order to facilitate the simultaneous transfer of multiple cigarette packs, multiple transfer rollers 32 are divided into N groups, N≥2; N groups of transfer rollers 32 are arranged in parallel along the length direction of the transfer frame 31; N-1 mounting plates 34 are arranged on the transfer frame 31, and the N-1 mounting plates 34 are arranged at intervals along the length direction of the transfer frame 31, and the interval between two adjacent mounting plates 34 or between the side wall of the transfer frame 31 in the width direction and the corresponding mounting plate 34 is adapted to the length of the transfer roller 32; the two ends of the N groups of transfer rollers 32 are respectively installed on the side wall of the transfer frame 31 in the width direction and the corresponding mounting plate 34, or are respectively installed on two adjacent mounting plates 34; the number of guide rollers 33 in each group is N, and the N guide rollers 33 are arranged in parallel along the length direction of the transfer frame 31, and correspond one-to-one to the N groups of transfer rollers 32, so that during transfer, the N cigarette packs can be quickly transferred through the N guide rollers 33 and the corresponding group of transfer rollers 32, respectively, so as to further improve the transfer efficiency and realize the simultaneous transfer of multiple cigarette packs.

[0046] In a preferred embodiment of the present invention, see Figure 1, multiple transfer rollers 32 are divided into two groups; the two groups of transfer rollers 32 are arranged in parallel along the length direction of the transfer frame 31; a mounting plate 34 is provided on the transfer frame 31, and the interval between the side wall of the transfer frame 31 in the width direction and the mounting plate 34 is adapted to the length of the transfer roller 32; the two ends of the two groups of transfer rollers 32 are respectively installed on the side wall of the transfer frame 31 in the width direction and the mounting plate 34; the number of guide rollers 33 in each group is 2, and the two guide rollers 33 are arranged in parallel along the length direction of the transfer frame 31, and correspond one by one to the two groups of transfer rollers 32.

[0047] Considering that when pulling cigarette packs, a certain driving force will be applied to the transfer vehicle itself, which will cause the transfer vehicle to deviate relative to the frame and move with the cigarette packs, making it inconvenient to transfer the cigarette packs. In this embodiment, a hook 6 is installed at each of the four corners of the vehicle body 1, and the long straight section of each hook 6 extends along the width direction of the vehicle body 1; two hooks 6 adjacent along the length direction of the vehicle body 1 are defined as the same group; the bent parts of the two hooks 6 in the same group are arranged back to back, and are used to be connected to the frame respectively, so that the vehicle body 1 can be connected to the frame as a whole when pulling the cigarette packs, avoiding the problem of difficulty in transferring cigarette packs caused by the shaking of the vehicle body 1.
