Description

Technical Field

[0001] The present invention relates to the technical field of cigarette product quality detection, and in particular to a tumbling multi-stage cigarette sorting device and a cigarette sorting method. Background Art

[0002] In the cigarette production process, after the tobacco passes through the tobacco-rolling machine suction and forming system, the moisture density and weight distribution of the tobacco bundle of the cigarette changes, which in turn affects the release of harmful substances in the cigarette smoke, and also affects the sensory quality during the cigarette consumption process, and thus affects consumers' recognition of cigarette products. At present, domestic cigarette manufacturers have begun to pay attention to the moisture density and weight distribution of cigarettes. In the comprehensive screening instrument for the moisture density and weight distribution characteristics of cigarettes, for testing cigarettes, after completing the moisture density and weight test, how to put the sample with the highest similarity into the designated container and how to sort out the cigarette samples of different standards and how to fall into the corresponding area is of great significance.

[0003] In the existing cigarette sorting device, cigarettes are weighed by the weighing mechanism and fall directly into the receiving box of the sorting device. Due to the effect of gravity, tobacco shreds may fall off during the falling process. In addition, cigarettes often fail to fall smoothly into the corresponding receiving box during the falling process and require manual assistance. The sorted cigarettes are messy and need to be sorted manually, which is inefficient. In addition, the cigarettes will be damaged during the falling or manual sorting process. This results in the cigarettes with high moisture density and weight similarity determined in the previous detection process not having the same indicators after they actually fall into the receiving box, which affects the next test use. Summary of the invention

[0004] In the comprehensive screening instrument for the moisture density and weight distribution characteristics of cigarettes, it is necessary to quickly and automatically find the sample with the closest three-factor distribution characteristics from a number of cigarette samples and put the sample with the highest similarity into a designated container. The instrument has a total of 6 screening containers for holding samples with different characteristics, and how to design the sorting device has become an important issue for the instrument.

[0005] According to the overall layout, the present invention takes into account the convenience of user operation and high maintainability, and adopts a design in which the sorting mechanism is arranged in a single row and a unit. At the same time, the entire sorting mechanism is arranged in a forward drawer, which can be easily pulled out to expose the mechanism, making operation and maintenance convenient.

[0006] At the same time, a partition board is added inside the large storage box to divide it into 6 grids, and the entire storage box is located under the sorting unit for receiving materials.

[0007] The purpose of the present invention is to provide a tumbling multi-stage cigarette sorting device and a cigarette sorting method with stable working performance and simple maintenance, so as to solve the technical problem of quickly and automatically placing the cigarette samples with the highest similarity into a designated container.

[0042] (9) When the picker is connected to negative pressure, the cigarette can be adsorbed on its inner wall, and when the negative pressure is cut off, the cigarette will fall naturally under the action of gravity.

[0043] The present invention has the following advantages over the prior art:

[0044] 1. The tumbling multi-stage cigarette sorting device of the present invention comprises a cigarette picker 1, a screening panel 2, a partition panel 3 and a storage box 4. The storage box 4 comprises N receiving boxes 41, each receiving box 41 corresponds to an independent screening channel that does not affect each other. The cigarette picker 1 is connected to a negative pressure device to absorb cigarettes from the previous process. The negative pressure device is cut off, and the cigarettes absorbed by the cigarette picker 1 fall into the corresponding receiving box 41 through the independent screening channel opening. The screening panel 2 of the sorting device of the present invention has multiple screening channel baffles 21.

DETAILED DESCRIPTION

[0054] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0055] like Figure 1 As shown, a rolling multi-stage cigarette sorting device comprises a cigarette picker 1, a screening panel 2, a partition panel 3 and a storage box 4;

[0056] The cigarette picker 1 is arranged at the front end of the screening panel 2. The cigarette picker 1 is composed of a left picker 11 and a right picker 12 which can rotate separately. One end of the left (right) picker is a semi-tubular structure, and the other end is a tubular channel. Negative pressure adsorption holes 121 are opened inside the semi-tube. The semi-tube of the left picker 11 and the semi-tube of the right picker 12 are spliced ​​to form a tubular channel running through both ends of the cigarette picker 1.

[0057] When loading cigarettes, the tubular channel of the cigarette picker 1 is in a vertical state, and the cigarettes fall vertically into the tubular channel of the cigarette picker 1. The negative pressure adsorption hole 121 is connected to the negative pressure gas source through a pipeline, and the cigarettes are adsorbed on the inner wall of the semi-tubular structure 111 of the left (right) picker;

[0058] The screening panel 2 is arranged perpendicularly to the partition panel 3. Four screening channel baffles 21 marked as No. 1, No. 2, No. 4 and No. 5 are distributed on the screening panel 2, two on the left and two on the right. Six cigarette drop openings 31, No. 1 to No. 6, are evenly arranged on the partition panel 3. The No. 3 and No. 6 cigarette drop openings 31 of the partition panel 3 also serve as No. 3 and No. 6 screening channel baffles 21; the No. 1, No. 2, No. 4 and No. 5 screening channels on the screening panel 2 correspond to the No. 1, No. 2, No. 4 and No. 5 cigarette drop openings 31 on the partition panel 3, respectively. When the half-tubes of the left picker 11 and the right picker 12 are in a horizontal position, the lower parts of the half-tubes are respectively facing the No. 3 and No. 6 cigarette drop openings 31. The No. 1 to No. 6 cigarette drop openings 31 on the partition panel 3 correspond to a receiving box 41, respectively.

[0059] During sorting, the left (right) picker is controlled so that the half tube of the left (right) picker is in a horizontal position, the negative pressure is cut off, and the cigarettes fall, and fall into the corresponding receiving box 41 from the cigarette drop port 31 just below the half tube of the left (right) picker.

[0060] The sorting device also includes a rotating cylinder 5, which can control the rotation of the left picker 11 and the right picker 12, so that the half tubes of the left picker 11 and the right picker 12 can be freely switched between the horizontal and vertical states. By turning the half tubes of the left picker 11 and the right picker 12 from a vertical setting to a horizontal setting, the cigarettes can be placed horizontally, thereby reducing the loss of falling cigarettes.

[0061] The tubular passages passing through the two ends of the cigarette picker 1 have a limiting and guiding function. When a cigarette falls vertically into the picker 1, it can be automatically limited, thereby realizing automatic clamping of the workpiece.

[0062] The storage box 4 is in the shape of a drawer, and the material receiving box 41 can be pushed in and pulled out to facilitate taking out materials.

[0063] The screening channel baffles 21 can be opened and closed individually.

[0064] A material guide plate 23 is connected to the bottom of the screening channel baffle 21, and the material guide plate 23 is located at the rear end of the screening panel 2. When the screening channel baffle 21 is opened, the screening channel baffle 21 is inclined at a large angle, and the material guide plate 23 at the bottom extends to the corresponding cigarette dropping port 31. When the cigarette falls, it slides along the material guide plate 23 and falls into the corresponding material receiving box 41.

[0065] The cigarette sorting method of the tumbling multi-stage cigarette sorting device of the present invention comprises the following steps:

[0066] A. The tubular channel of the cigarette picker 1 is in a vertical position, and the left (right) picker tubular channel is connected to negative pressure;

[0067] B. When loading cigarettes, the cigarettes are adsorbed on the inner wall of the left (right) semi-tubular picker under the action of negative pressure;

[0068] C. Control the left (right) picker by rotating the cylinder 5 so that the half pipe is in a horizontal position;

[0069] D. The cigarettes pass through the screening channel baffle 21 or directly fall into the corresponding receiving box 41 through the cigarette drop opening 31 .

[0070] like Figure 5 When the baffle plate 21 of screening channel No. 1 is opened, the half pipe of the left picker is in a horizontal position by rotating the cylinder 5, and the negative pressure of the left picker 11 is cut off. The cigarettes fall into the baffle plate 21 of screening channel No. 1 due to gravity, slide into the cigarette drop port 31 of No. 1 along the guide plate 23, and fall into the corresponding receiving box 41 of No. 6.

[0071] The sorting device is arranged below the microwave measuring mechanism. In order to facilitate operation and maintenance, the sorting device is made into a drawer-type structure.

[0072] Two cigarette pickers are arranged on both sides of the microwave mechanism. They are in a specific semi-tubular shape. The two pickers are combined to form a tubular channel, which plays a role in guiding and limiting cigarettes. The two pickers are respectively equipped with a rotating cylinder, which can change the picker from a vertical state to a horizontal state. Negative pressure adsorption holes are opened on the inner wall of the tubular, and the cigarettes are adsorbed on the inner wall of the tubular picker by negative pressure.

[0073] The sorting device is located below the microwave mechanism. There are 4 channel doors on the sorting panel, which can be opened when needed. The cigarettes dropped from the picker will be caught by the channel doors, and then roll down the channel into the corresponding storage compartment under gravity.

[0074] The 6-compartment storage box is located below the sorting device, and each compartment corresponds to a sorting channel.

[0075] The device is equipped with 6 screening channels. The entrances of channel 2 are located on the isolation plate, vertically facing the picker, and the cigarettes fall directly into the corresponding partition of the storage box below the channel entrance; channel 4 is located on the screening panel and falls into the storage box through a large-angle slope rolling channel.

[0076] When the sample needs to be placed in channel 1, the cover of channel 1 will open as shown in the figure below. After the left picker turns the cigarette to a horizontal state, the control system cuts off the adsorption negative pressure. The cigarette sample falls under gravity and is caught by the cover of channel 1. Then the sample rolls along the guide slope into the target storage box partition.

[0077] When the sorting mechanism is in standby state, the two pickers are closed. Figure 1 As shown. After the microwave measurement of cigarettes is completed, the upper computer controls the left (right) picker to connect to negative pressure, and the cigarette is firmly adsorbed on the tubular inner wall of the picker under the action of negative pressure, and then the rotating cylinder moves the cigarette to a horizontal state. At the same time, the corresponding channel door will open, and the negative pressure will be cut off. The cigarette will fall and be directly caught by the channel door, and then the cigarette will roll along the channel guide plate into the corresponding storage box compartment.

[0078] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
