Description

Technical Field

[0001] The present invention relates to the technical field of tobacco equipment, and in particular to a method for distributing materials in a tobacco cache cabinet. Background Art

[0002] On the tobacco shredding production line, in order to ensure the continuous production and stable material supply of the subsequent processes of the shredding process, the production capacity of the shredding machine is greater than the production capacity of the subsequent processes. A small cache cabinet will be installed after shredding to cache the produced tobacco.

[0003] Existing buffer cabinets use a stacking feed method, distributing tobacco starting at the outlet and working backwards, with the overall operation mode being a simultaneous feed and discharge. In actual production, this stacking method is used along the central axis of the buffer cabinet, resulting in tobacco being stored higher in the middle and lower on the sides. This uneven distribution of tobacco reduces the buffer cabinet's storage efficiency. This uneven distribution also causes fluctuations in the buffer cabinet's discharge flow rate, affecting the flow stability of subsequent processes and compromising process quality.

[0004] Therefore, there is an urgent need for a tobacco cache cabinet fabric method to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a tobacco cache cabinet distributing method, which can evenly distribute the tobacco material in the cache cabinet, ensure the storage efficiency of the tobacco material, reduce the fluctuation of the cache cabinet discharge flow rate, and ensure the flow stability of the subsequent process.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A method for distributing material in a tobacco cache cabinet, comprising:

[0008] S1. Divide the fabric area of ​​the fabric car into three areas according to the width of the fabric car. The width of each area is one-third of the width of the fabric car. The three areas are Area I, Area II, and Area III. The diffuse reflection photoelectric switch in Area I, the diffuse reflection photoelectric switch in Area II, and the diffuse reflection photoelectric switch in Area III are installed at the center points of Area I, Area II, and Area III, respectively.

[0009] S2. Setting the position of the guide plate, wherein the guide plate is rotatably arranged at the material outlet of the material distribution vehicle, and the guide plate can be rotated to the area I, the area II, and the area III;

[0010] S3, feeding process and feeding priority: when the material distribution vehicle reaches the material distribution position, it distributes the material to the three areas. When the material distribution in the three areas reaches the set height at the same time, the material distribution vehicle moves backward to the next material distribution position. The distribution order priority of the three areas is area II > area I > area III;

[0011] S4. The transmitting end of the laser rangefinder assembly is installed on the cabinet body at the discharge end of the cache cabinet, and the reflector of the laser rangefinder assembly is installed at the head position of the material distribution vehicle feeding. The laser rangefinder assembly measures the real-time position of the material distribution vehicle feeding;

[0012] S5. Establishing a data table of the counting variable M and the height of the position points of the material distribution vehicle in a database;

[0013] S6. According to each sub-position in the position point height data table of the database, the tobacco material is laid in the area where the tobacco material collapses and the height does not reach the set height, and the order is from front to back. After the material replenishment in the current area is completed and the tobacco material in the current area reaches the set height, the corresponding data in the position point height data table is reset.

[0014] Optionally, in step S2, the guide plate is connected to a servo via a connecting shaft, and the rotation angle of the servo determines the blanking angle of the guide plate.

[0015] Optionally, the mounting surface of the servo is used as a reference surface to divide the feeding angles into three zones, and the three zone feeding angles are respectively the feeding angle of zone I, the feeding angle of zone II and the feeding angle of zone III. The feeding angle of zone II is the axial middle position of the cache cabinet, the feeding angle of zone II is 90°, the initial setting angle of the feeding angle of zone I is 45°, and the initial setting angle of the feeding angle of zone III is 135°.

[0016] Optionally, when the tobacco material in zone I approaches the tobacco material in zone II, the feeding angle of zone I is reduced by 5°; when the tobacco material in zone III approaches the tobacco material in zone II, the feeding angle of zone III is increased by 5°.

[0017] Optionally, in the S3 step:

[0018] When the diffuse reflection photoelectric switch of zone I, the diffuse reflection photoelectric switch of zone II, and the diffuse reflection photoelectric switch of zone III detect that the height of the tobacco material in the corresponding area has not reached the set height, the distribution vehicle will give priority to feeding the tobacco material into zone II. When the tobacco material in zone II reaches the set height, the distribution vehicle will sequentially feed the tobacco material into zones I and III.

[0019] When the tobacco distribution vehicle is feeding the tobacco material in area I or area III, and the tobacco material level in area II drops below the set level, the guide plate rotates to area II, and the tobacco distribution vehicle feeds the tobacco material into area II; after the tobacco material in area II reaches the set level, the guide plate rotates to area I, and the tobacco distribution vehicle feeds the tobacco material into area I; if the tobacco material in area I is at the set level, the guide plate rotates to area III, and the tobacco distribution vehicle feeds the tobacco material into area III;

[0020] When the distribution vehicle is feeding the zone III, if the height of the tobacco material in the zone I drops and does not reach the set height, the guide plate rotates to the zone I and the distribution vehicle feeds the zone I; after the height of the tobacco material in the zone I reaches the set height, the guide plate rotates to the zone III and the distribution vehicle feeds the zone III.

[0021] Optionally, in step S4, the material distribution area of ​​the cache cabinet is mapped to an XY coordinate system, wherein the X-axis represents the positions of the diffuse reflection photoelectric switch in zone I, the diffuse reflection photoelectric switch in zone II, and the diffuse reflection photoelectric switch in zone III, respectively; the position of the diffuse reflection photoelectric switch in zone I is set to 1, the position of the diffuse reflection photoelectric switch in zone II is set to 2, and the position of the diffuse reflection photoelectric switch in zone III is set to 3; and the Y-axis direction represents the axial running distance of the material distribution vehicle.

[0022] Optionally, the cloth starting position of the cloth cart is taken as the origin position with coordinates (0,0), and 100 mm is used as the graduation position to divide the cloth cart into corresponding areas. The specific number of positions is calculated based on the cloth distance of the cache cabinet. The calculation formula is: cache cabinet cloth distance S / 100, in mm, and a grid position table is established.

[0023] Optionally, in step S5, after the material distribution vehicle completes feeding at the current position, the counting variable M is increased by 1. When the value of the counting variable M is equal to 20, the current material distribution is stopped, and the material distribution vehicle moves to position 0 in the Y-axis direction.

[0024] Optionally, during the movement of the cloth vehicle, the position where the height of the tobacco material does not reach the set height is recorded, and the corresponding data setting operation is performed in the corresponding position point height data table, which is stored in the database. 0 or 1 is filled in the table. Filling in 1 indicates that the height does not reach the set height; filling in 0 indicates that the height reaches the set height.

[0025] Optionally, in step S6, after completing all the material replenishment operations in the position point height data table in the database, the material distribution vehicle searches for the next material distribution position to continue distribution, and the counting variable M of the material distribution vehicle is reset to zero.

[0026] Beneficial effects of the present invention:

[0027] The present invention provides a method for distributing material in a tobacco cache cabinet. A diffuse reflection photoelectric switch for Zone I, a diffuse reflection photoelectric switch for Zone II, and a diffuse reflection photoelectric switch for Zone III are respectively provided at the center points of Zone I, Zone II, and Zone III of a distributing vehicle. The diffuse reflection photoelectric switches for Zone I, Zone II, and Zone III detect the height of tobacco material in the corresponding zones. When the tobacco material does not reach the set height, the guide plate rotates to the corresponding zone. When the material in the three zones reaches the set height simultaneously, the distributing vehicle moves backward to the next distributing position. The distributing order priority for the three zones is Zone II > Zone I > Zone III. Distributing material is performed in the zone where the tobacco material collapses and does not reach the set height, in a front-to-back order. This method for distributing material in a tobacco cache cabinet can evenly distribute tobacco material within the cache cabinet, ensure tobacco material storage efficiency, reduce fluctuations in the discharge flow of the cache cabinet, and ensure flow stability in subsequent processes.

[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] like Figures 1 to 5 As shown, this embodiment provides a method for distributing materials in a tobacco cache cabinet, comprising:

[0043] S1. Divide the fabric distribution area of ​​the fabric distribution vehicle 100 into three areas according to the width of the fabric distribution vehicle 100. The width of each area is one-third of the width of the fabric distribution vehicle 100. The three areas are Area I, Area II, and Area III. The diffuse reflection photoelectric switch 200 in Area I, the diffuse reflection photoelectric switch 300 in Area II, and the diffuse reflection photoelectric switch 400 in Area III are installed at the center points of Area I, Area II, and Area III, respectively.

[0044] S2. Setting the position of the guide plate 500. The guide plate 500 is rotatably arranged at the material outlet of the material distribution vehicle 100. The guide plate 500 can be rotated to areas I, II, and III.

[0045] S3. Material feeding process and feeding priority. When the material feeding vehicle 100 reaches the material feeding position, it performs material feeding operations on the three areas. When the material feeding in the three areas reaches the set height at the same time, the material feeding vehicle 100 moves backward to the next material feeding position. The material feeding order priority of the three areas is Area II > Area I > Area III.

[0046] S4. The transmitting end 600 of the laser rangefinder assembly is installed on the cabinet body at the discharge end of the buffer cabinet 800, and the reflecting plate 700 of the laser rangefinder assembly is installed at the head position of the material distribution vehicle 100. The laser rangefinder assembly measures the real-time position of the material distribution vehicle 100;

[0047] S5. Establishing a counting variable M and a position point height data table of the material distribution vehicle 100 in the database;

[0048] S6. According to the various positions in the position point height data table of the database, the tobacco material is laid in the area where the height of the collapsed tobacco material does not reach the set height, and the order is from front to back. After the filling of the current area is completed and the tobacco material in the current area reaches the set height, the corresponding data in the position point height data table is reset.

[0049] The present embodiment provides a method for distributing tobacco cache materials. A diffuse reflection photoelectric switch 200 for Zone I, a diffuse reflection photoelectric switch 300 for Zone II, and a diffuse reflection photoelectric switch 400 for Zone III are respectively positioned at the center points of Zone I, Zone II, and Zone III of a distribution vehicle 100. The diffuse reflection photoelectric switches 200, 300, and 400 detect the height of tobacco material within the corresponding zones. If the tobacco material does not reach the set height, the guide plate 500 rotates to the corresponding zone. When the tobacco material in all three zones reaches the set height simultaneously, the distribution vehicle 100 moves backward to the next distribution position. The distribution order for the three zones is Zone II > Zone I > Zone III. Distribution is performed in the zone where the tobacco material collapses and does not reach the set height, in a forward-to-backward order. This method for distributing tobacco cache materials evenly within the cache 800, ensuring tobacco material storage efficiency, reducing fluctuations in the discharge flow rate of the cache 800, and ensuring flow stability in subsequent processes.

[0050] For example, the width of the material distribution vehicle 100 is L, which is divided into three areas, each of which is 1 / 3 L. The center point of each area is the specific position of the diffuse reflection photoelectric switch. The function of each partition diffuse reflection photoelectric switch is to measure the height of the tobacco material in its respective area.

[0051] In some specific embodiments, in step S2, the guide plate 500 is connected to the steering gear 520 via the connecting shaft 510. The rotation angle of the steering gear 520 determines the blanking angle of the guide plate 500, and the steering gear 520 drives the guide plate 500 to rotate. The mounting surface of the steering gear 520 is used as a reference plane to divide the feed angle into three zones: Zone I, Zone II, and Zone III. The Zone II feed angle is located at the axial center of the cache 800. The Zone II feed angle is 90°. The initial setting angles for Zone I and Zone III are 45° and 135°, respectively. The specific adjustment method is as follows: when the tobacco material in Zone I approaches the tobacco material in Zone II, the Zone I feed angle is reduced by 5°; when the tobacco material in Zone III approaches the tobacco material in Zone II, the Zone III feed angle is increased by 5°.

[0052] Optionally, in the S3 step:

[0053] In case 1, when the diffuse reflection photoelectric switch 200 of zone I, the diffuse reflection photoelectric switch 300 of zone II, and the diffuse reflection photoelectric switch 400 of zone III detect that the tobacco material height in the corresponding areas has not reached the set height, the material distribution vehicle 100 will first feed the tobacco material into zone II. When the tobacco material in zone II reaches the set height, it will then feed into zones I and III in sequence.

[0054] Case 2: When the tobacco distribution vehicle 100 is feeding into Zone I or Zone III, and the tobacco material level in Zone II drops below the set height, the guide plate 500 rotates to Zone II, and the distribution vehicle 100 feeds into Zone II. After the tobacco material in Zone II reaches the set height, the guide plate 500 rotates to Zone I, and the distribution vehicle 100 feeds into Zone I. If the tobacco material in Zone I is at the set height, the guide plate 500 rotates to Zone III, and the distribution vehicle 100 feeds into Zone III.

[0055] Case 3: When the tobacco distribution vehicle 100 is feeding into Zone III, and the tobacco material level in Zone I drops below the set level, the guide plate 500 rotates to Zone I, and the tobacco distribution vehicle 100 feeds into Zone I. After the tobacco material level in Zone I reaches the set level, the guide plate 500 rotates to Zone III, and the tobacco distribution vehicle 100 feeds into Zone III.

[0056] Case 4: When the distribution vehicle 100 is feeding into zone III, if the height of the tobacco material in zone II drops and does not reach the set height, refer to case 2. Thus, the tobacco material that has not reached the set height is replenished during the distribution process of the distribution vehicle 100.

[0057] In some specific embodiments, in step S4, the fabric area of ​​the cache cabinet 800 is mapped to an XY coordinate system, where the X-axis represents the positions of the diffuse reflection photoelectric switch 200 in zone I, the diffuse reflection photoelectric switch 300 in zone II, and the diffuse reflection photoelectric switch 400 in zone III, respectively; the position of the diffuse reflection photoelectric switch 200 in zone I is set to 1, the position of the diffuse reflection photoelectric switch 300 in zone II is set to 2, and the position of the diffuse reflection photoelectric switch 400 in zone III is set to 3; and the Y-axis direction represents the axial running distance of the fabric cart 100.

[0058] The cloth starting position of the cloth cart 100 is taken as the origin position with coordinates (0,0), and 100 mm is used as the division position to divide the cloth cart 100 into corresponding areas. The specific number of positions is calculated according to the cloth distance of the cache cabinet 800. The calculation formula is: the cloth distance of the cache cabinet 800 S / 100, in mm, and a grid position table is established. The grid position table is as shown in the following table.

[0059] x / y 1 2 3 100 (1,100) (2,100) (3,100) 200 (1,200) (2,200) (3,200) 300 (1,300) (2,300) (3,300) 400 (1,400) (2,400) (3,400) 500 (1,500) (2,500) (3,500)

[0060] In step S5, after the distribution vehicle 100 completes loading at the current position, the counter variable M is incremented by 1. When the counter variable M reaches 20, the current distribution process is stopped and the distribution vehicle 100 moves along the Y axis to position 0. During the movement of the distribution vehicle 100, the locations where the tobacco material height does not reach the set height are recorded. The corresponding data in the corresponding position height data table is set and stored in the database. The table is filled with 0 or 1. A value of 1 indicates that the height has not reached the set height; a value of 0 indicates that the height has reached the set height. The position height data table is shown below.

[0061] x / y 1 2 3 100 0 / 1 0 / 1 0 / 1 200 0 / 1 0 / 1 0 / 1 300 0 / 1 0 / 1 0 / 1 400 0 / 1 0 / 1 0 / 1 500 0 / 1 0 / 1 0 / 1

[0062] Specifically, in step S6, after completing all the material replenishment operations in the position point height data table in the database, the material distribution vehicle 100 searches for the next material distribution position to continue distribution, and the counting variable M of the material distribution vehicle 100 is reset to zero.

[0063] For example, after the distribution vehicle 100 reaches position 0 along the Y axis, it distributes tobacco to areas where the tobacco material has collapsed and has not reached the set height, according to the locations in the database's position point height data table. This order is from front to back, i.e., from position 0. After refilling at that location and the tobacco material at that location reaches the set height, the corresponding data in the position point height data table is reset, with the table being filled with 0. If multiple feeding areas at the same location do not reach the set height, the feeding order of these feeding areas (Zones I, II, and III) is adjusted based on the priority in step S3. After completing all refill operations in the database's position point height data table, the distribution vehicle 100 searches for the next feeding location, selects the next location based on the selection in S3, and continues distributing tobacco. The distribution vehicle 100's counter variable M is reset to zero.

[0064] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
