Description

Technical Field

[0001] This invention relates to automatic cigarette tray loading equipment, and particularly to an automatic cigarette tray loading device. Background Technology

[0002] In the offline integrated quality testing process for tobacco, inspectors need to take samples from finished cigarettes and sequentially test multiple physical indicators, including cigarette weight, circumference, draw resistance, hardness, end powder content, empty ends, filter tip, and cigarette surface. After testing, the tested cigarettes need to be neatly stacked back into the empty cigarette tray for retesting, sample retention, or batch archiving. Currently, laboratories generally use manual tray loading, where operators must straighten the orientation of each cigarette and neatly stack them into the tray. Because offline testing involves multiple batches and specifications of samples, and while the quantity tested per session is moderate, the frequency is high. Manual tray loading not only consumes a significant amount of testing time, but also easily leads to uneven cigarette arrangement, end damage, or sample confusion due to prolonged repetitive manual work. Existing automated tray loading equipment is mostly designed for production lines, is bulky, and cumbersome to change, making it difficult to meet the actual needs of limited laboratory space, frequent sample turnover, and high requirements for cigarette integrity. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automatic cigarette tray loading device, specifically designed for sample handling scenarios after offline comprehensive quality inspection. It aims to solve the problems of low efficiency, fragile cigarettes, and sample confusion associated with manual tray loading. This device achieves stable collection and orderly stacking of tested cigarettes through the coordinated operation of a cigarette storage bin mechanism, a belt-driven cigarette dropping mechanism, and a cigarette collection and tray loading mechanism.

[0004] The automatic cigarette tray loading device provided by this invention has the following technical solution: An automatic cigarette tray loading device includes a cigarette storage bin mechanism (1), a left belt conveyor cigarette dropping mechanism (2), a right belt conveyor cigarette dropping mechanism (3), a horizontal cigarette collection and tray loading mechanism (4), a vertical cigarette collection and tray loading mechanism (5), a cigarette receiving plate (6), and a cigarette tray (7). The cigarette storage bin mechanism (1) is the cigarette inlet of the entire device; the cigarette receiving plate (6) is fixed on the belt of the right belt conveyor cigarette dropping mechanism (3), and can carry the cigarettes down with the belt. The right belt conveyor cigarette dropping mechanism (3) is driven by a servo motor to rotate counterclockwise from the cigarette receiving position. The cigarette receiving position is determined by the zero position sensor (201); the cigarette receiving plate (6) stops rotating after reaching the bottom position of the right belt conveyor cigarette dropping mechanism (3). During the cigarette loading process, the cigarette receiving plate (6) is kept at the bottom of the right belt conveyor cigarette dropping mechanism (3) and plays the role of blocking the smoke when the cigarettes are placed on the tray; when the right belt conveyor cigarette dropping mechanism (3) stops rotating after it reaches the bottom position, the transverse cigarette collection and tray mechanism (4) drives the second lead screw (30) through the forward or reverse rotation of the motor. 2) Rotate to move the cigarette tray (7) left and right to fill the cigarette tray (7) with cigarettes; after each left and right stroke of the horizontal cigarette collection and loading mechanism (4), the vertical cigarette collection and loading mechanism (5) drives the first lead screw (301) to rotate by the motor to rotate forward or reverse, which drives the cigarette tray (7) to descend and maintain its position. Then the horizontal cigarette collection and loading mechanism (4) repeats the left and right stroke to fill the cigarette tray (7) with the next layer of cigarettes until the cigarette tray (7) is full; during the cigarette loading process, the left belt conveyor cigarette dropping mechanism (2) is driven by the servo motor to rotate the belt clockwise, which can ensure that the cigarettes fall smoothly and steadily. If there is a jam, the clockwise rotation of the belt can move the cigarettes to make them neat; an acrylic door panel (202) is added in the middle of the belt to make the cigarette ends flat.

[0005] Furthermore, the cigarette storage bin mechanism (1), the left belt conveyor cigarette dropping mechanism (2), the right belt conveyor cigarette dropping mechanism (3), the horizontal cigarette collection and loading mechanism (4), the vertical cigarette collection and loading mechanism (5), and the cigarette receiving plate (6) are fixed on the bracket.

[0006] Furthermore, a smoke baffle (8) is provided at the bottom of the left belt conveyor cigarette dropping mechanism (2). The function of the smoke baffle (8) is to make the cigarettes fall neatly into the cigarette tray (7).

[0007] Furthermore, the cigarette tray (7) is locked and fixed by clamps at both ends, and can be removed after being filled with cigarettes.

[0008] Furthermore, the cigarette storage bin mechanism (1) includes an arc-shaped guard plate (101), a storage rotating plate (102), a cigarette inlet baffle (103), a counterweight (104), a storage bin back plate (105), an arc-shaped plate (106), and three feeding sensors (107). The arc-shaped guard plate (101), the storage rotating plate (102), the cigarette inlet baffle (103), the arc-shaped plate (106), and the three feeding sensors (107) are all mounted on the storage bin back plate (105). The counterweight (104) and the storage rotating plate (102) form a lever structure, which can realize the rotation of the storage plate under the pressure of the cigarette. (102) is raised or lowered; three feeding sensors (107) are set at intervals; initially, the cigarettes enter from between the arc-shaped guard plate (101) and the smoke inlet baffle (103), and slowly accumulate until the storage rotating plate (102) is raised. When the first sensor from left to right has a signal, the left belt conveyor cigarette dropping mechanism (2) and the right belt conveyor cigarette dropping mechanism (3) start to transport the cigarettes downward. When the second sensor has a signal, the horizontal cigarette collection tray mechanism (4) and the vertical cigarette collection tray mechanism (5) start to distribute the cigarettes. When the third sensor has a signal, the cigarette storage bin is too full and the cigarette feeding is suspended.

[0009] The implementation of this invention has the following technical effects: 1. Ensure sample integrity: Through the linkage control of the feeding sensor and the belt conveyor, the cigarette receiving plate is slowly lowered and the cigarette is smoothly transferred, avoiding end dents or filter deformation caused by the free fall of the cigarette. This ensures that the cigarette shape is intact after comprehensive quality inspection and meets the requirements for re-inspection and sample retention.

[0010] 2. Adaptable to the characteristics of multiple specifications and high frequency of offline testing: The device has a compact structure and is easy to arrange flexibly on the laboratory table; the cigarette collection tray mechanism can automatically fall and move left and right, which can quickly adapt to different specifications of cigarettes, and is suitable for the use scenario of multiple sample batches and frequent switching in offline testing.

[0011] 3. Improved efficiency and standardization: Automated tray loading replaces manual stacking of cigarettes one by one, greatly reducing repetitive labor for quality inspectors. At the same time, it reduces direct contact between hands and cigarettes, avoids cross-contamination of samples, and ensures the standardization of the quality inspection process and the traceability of samples.

[0016] The present invention will now be described in detail with reference to the embodiments and accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention and do not constitute any limitation thereof.

[0017] See Figures 1 to 4As shown, this embodiment of an automatic cigarette tray loading device includes a cigarette storage bin mechanism 1, a left belt conveyor cigarette dropping mechanism 2, a right belt conveyor cigarette dropping mechanism 3, a horizontal cigarette collection and tray loading mechanism 4, a vertical cigarette collection and tray loading mechanism 5, a cigarette receiving plate 6, and a cigarette tray 7. The cigarette storage bin mechanism 1 is the cigarette inlet of the entire device. The cigarette receiving plate 6 is fixed on the belt of the right belt conveyor cigarette dropping mechanism 3 and can carry cigarettes and move downward with the belt. The right belt conveyor cigarette dropping mechanism 3 is driven by a servo motor to rotate counterclockwise from the cigarette receiving position. The cigarette receiving position is determined by a zero-position sensor 201. The cigarette receiving plate 6 stops rotating after reaching the bottom position of the right belt conveyor cigarette dropping mechanism 3. During the cigarette loading process, the cigarette receiving plate 6 remains at the bottom of the right belt conveyor cigarette dropping mechanism 3 and plays a role in blocking smoke when loading cigarettes onto the tray. After the cigarette dropping mechanism 3 stops rotating, the horizontal cigarette collecting and loading mechanism 4 drives the second lead screw 302 to rotate via the forward or reverse rotation of the motor, causing the cigarette tray 7 to move left and right to load cigarettes into the tray 7. After each left and right stroke of the horizontal cigarette collecting and loading mechanism 4, the vertical cigarette collecting and loading mechanism 5 drives the first lead screw 301 to rotate via the forward or reverse rotation of the motor, causing the cigarette tray 7 to descend a certain distance and maintain its position. Then, the horizontal cigarette collecting and loading mechanism 4 repeats the left and right strokes to load the next layer of cigarettes into the cigarette tray 7 until the tray 7 is full. During the loading process, the left-side belt conveyor cigarette dropping mechanism 2 is driven by a servo motor to rotate the belt clockwise, which can ensure that the cigarettes fall smoothly and steadily. If jamming occurs, the clockwise rotation of the belt can move the cigarettes to make them neat. An acrylic door panel 202 is installed in the middle of the belt to make the cigarette ends flat. The cigarette storage bin mechanism 1, the left belt conveyor cigarette dropping mechanism 2, the right belt conveyor cigarette dropping mechanism 3, the horizontal cigarette collection and tray mechanism 4, the vertical cigarette collection and tray mechanism 5, and the cigarette receiving plate 6 are all fixed on the bracket. A smoke baffle 8 is installed at the bottom of the left belt conveyor cigarette dropping mechanism 2. The function of the smoke baffle 8 is to ensure that the cigarettes fall neatly into the cigarette tray 7. The cigarette tray 7 is locked in place by clamps at both ends and can be removed after being filled with cigarettes. When the device starts loading cigarettes, the zero-position sensor 201 determines that the cigarette receiving plate 6 is at the top and in the cigarette receiving position (zero position). The cigarettes in the cigarette storage bin mechanism 1 enter the cigarette receiving plate 6. The cigarette receiving plate 6 carrying the cigarettes is brought to the bottom position by the right belt conveyor cigarette dropping mechanism 3 and stops rotating. Then, the cigarettes are smoothly and steadily conveyed downward by the left belt conveyor cigarette dropping mechanism 2, which is constantly rotating, to realize the loading of the tray. The horizontal cigarette collecting and loading mechanism 4 and the vertical cigarette collecting and loading mechanism 5 drive the cigarette tray 7 to move left and right and descend to distribute the cigarettes layer by layer, so as to realize the automatic cigarette loading function of this device.

[0018] See Figure 2As shown, the cigarette storage bin mechanism 1 includes an arc-shaped guard plate 101, a storage rotating plate 102, a cigarette inlet baffle 103, a counterweight 104, a storage bin back plate 105, an arc-shaped plate 106, and three discharge sensors 107. The arc-shaped guard plate 101, the storage rotating plate 102, the cigarette inlet baffle 103, the arc-shaped plate 106, and the three discharge sensors 107 are all mounted on the storage bin back plate 105. The counterweight 104 and the storage rotating plate 102 form a lever structure, which can raise or lower the storage rotating plate 102 under the pressure of the cigarette. Three feeding sensors 107 are spaced apart. Initially, cigarettes slowly enter between the arc-shaped guard plate 101 and the smoke inlet baffle 103, gradually accumulating until the storage rotating plate 102 is lifted. When the first sensor from left to right receives a signal, the left belt conveyor cigarette dropping mechanism 2 and the right belt conveyor cigarette dropping mechanism 3 start transporting cigarettes downwards. When the second sensor receives a signal, the horizontal cigarette collection and tray mechanism 4 and the vertical cigarette collection and tray mechanism 5 start distributing cigarettes. When the third sensor receives a signal, the cigarette storage bin is too full, and cigarette feeding is suspended. Three feeding sensors 107 are installed on the back plate of the cigarette storage bin mechanism 1 to control the left belt conveyor cigarette dropping mechanism 2 and the right belt conveyor cigarette dropping mechanism 3 to transport cigarettes downwards, which has the functions of preventing cigarette shortage and cigarette jamming when the bin is full.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
