Description

Technical Field

[0001] The invention relates to the field of sorting devices, in particular to a falling dispersion mechanism and a sorting device. Background Art

[0002] In the traditional material handling process, especially for materials of various shapes such as tobacco leaves, there are often problems of material accumulation and overlap. In particular, in the tobacco leaf grading process, the piles of tobacco leaves are tightly packed and difficult to accurately read the size, which affects the grading efficiency and accuracy. Traditional solutions mostly rely on manual dispersion or use simple mechanical vibration for preliminary dispersion, but these methods are often inefficient and have poor dispersion effects, and cannot meet the needs of large-scale automated production. Summary of the invention

[0003] The purpose of the present invention is to provide a falling dispersion mechanism to solve the problem that the dispersion of piled tobacco leaves in the prior art mainly relies on manual labor, which has low efficiency and poor dispersion effect.

[0004] The technical solution of the present invention is: a falling dispersion mechanism, having an inlet and an outlet lower than the inlet, a falling channel for materials is formed between the inlet and the outlet, and a posture corrector is arranged in the falling channel; The posture corrector has an extension direction that is inclined downward; When the material falls, the end of the material close to the center of gravity abuts against the posture corrector, and this abutting action enables the material to continue falling in an unstable equilibrium posture after breaking away from the contact with the abutting surface.

[0005] Preferably, the posture corrector is provided in plurality, and the corresponding abutment surfaces of the plurality of posture correctors have different absolute heights; and the projections of the posture correctors with adjacent absolute heights on the same horizontal plane have overlapping parts, so that the material sliding down from any posture corrector can fall onto another abutment surface located at the adjacent absolute height below after a falling process of a preset stroke.

[0006] Preferably, posture correctors with adjacent absolute heights are staggered to form a zigzag structure.

[0007] Preferably, posture correctors having adjacent absolute heights extend in the same direction.

[0008] Preferably, the falling channel is closed along the circumferential direction, and a plurality of the posture correctors are staggeredly arranged on the parallel inner walls of the falling channel.

[0009] The sorting device comprises a first dispersing mechanism and a feeding mechanism; Preferably, the first dispersing mechanism comprises a loading bin, which has an absolute height lower than the feeding port and is connected to the feeding port via a lifting track; The unloading mechanism is arranged corresponding to the discharge port, and is used for conveying the material dropped from the discharge port in a direction away from the discharge port.

[0010] Preferably, partitions are provided on the lifting track, and multiple partitions are evenly arranged along the length direction of the lifting track and at preset intervals. The arrangement of multiple partitions forms a stacking area for accommodating a certain amount of materials between adjacent partitions.

[0011] Preferably, it includes a second dispersing mechanism, which is arranged at one end of the lifting track close to the feed port, and the second dispersing mechanism includes a feed plate that is higher than the feed port and inclined toward the feed port, and the feed plate can carry the material output by the lifting track and is connected to a vibrating table.

[0012] Preferably, the unloading mechanism includes a conveyor, and a guide is provided at one end of the conveyor away from the discharge port. The guide has a guiding end that can abut against the material, and the material abutting the guiding end is unloaded in a posture basically perpendicular to the running direction of the conveyor.

[0013] Compared with the prior art, the advantages of the present invention are: (1) The falling dispersion mechanism provided in the present application can make multiple tobacco leaves that enter in a concentrated manner fall as straight as possible during the falling process through a specially set posture corrector. This setting not only makes tobacco leaves of different sizes have different falling speeds when subjected to different air resistances, thereby achieving the dispersed laying of tobacco leaves and reducing overlapping, but also enables the non-overlapping tobacco leaves to be more accurately read by the visual camera photographed from top to bottom in the subsequent grading process.

[0014] (2) The present application further improves the dispersion of tobacco leaves by providing multiple posture correctors at different absolute heights and maintaining a preset vertical distance between them. This design enables tobacco leaves to maintain a straight posture and present a repeated correction process from leaving any posture corrector to entering the next posture corrector, thereby ensuring uniform dispersion of tobacco leaves throughout the entire drop channel.

[0015] (3) The present application also provides a sorting device formed by a combination of a falling dispersion mechanism, other dispersion mechanisms and a feeding mechanism. The sorting device can achieve the initial, secondary and final dispersion of tobacco leaves, and convey the dispersed tobacco leaves toward one end through the feeding mechanism. At the same time, a guide is provided to correct the skewness of the tobacco leaves so that they meet the requirements of subsequent grading equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with specific embodiments: like Figure 1 As shown, the present application provides a drop dispersion mechanism 100 for dispersing piled materials, having an inlet 111 at the top and an outlet 112 at the bottom. Its main working principle is: Combination Figure 1 , Figure 2As shown, multiple materials (hereinafter taking tobacco leaves 500 as an example) concentrated into the feed inlet 111 will fall under the action of gravity, and under the action of the specially arranged posture corrector 120, they will fall as straight as possible when falling, or it is called floating. Such arrangement enables multiple tobacco leaves 500 of different sizes to be subjected to different air resistances accordingly, and thus have different falling speeds. Therefore, they will fall successively into the horizontally operating unloading mechanism 400, achieving the effect that the tobacco leaves 500 concentrated into the feed inlet 111 are laid in a dispersed form in the unloading mechanism 400. In addition, the overlap between the tobacco leaves 500 is reduced, so that in the subsequent tobacco leaf 500 grading process, the non-overlapping tobacco leaves 500 can be better accurately read by the visual camera photographed from top to bottom.

[0018] Specifically, Figure 2 As shown, the drop dispersing mechanism 100 includes a drop channel 110, the top of which is configured as a material inlet 111, and the bottom of which is configured as a material outlet 112. Naturally, the outlet 112 has a height lower than the inlet 111, so that the tobacco leaves 500 entering the inlet 111 can move toward the outlet 112 under the action of gravity.

[0019] Here, some characteristics of the tobacco leaf 500 in the main application scenarios of this application are introduced in order to better understand the role of the posture corrector 120 in this application.

[0020] like Figure 3 As shown, the tobacco leaf 500 has a leaf surface 510 that occupies most of the volume, and a petiole 520 protruding at one end. Most of the moisture in the fresh tobacco leaf 500 is stored in the leaf surface 510. In the application scenario of the present application, the tobacco leaves 500 dispersed into the feed inlet 111 are tobacco leaves 500 after drying, and the internal moisture has been lost, so that the leaf surface 510 has a lighter weight while retaining a large volume. The petiole 520 is mainly composed of fibers, which loses less water relatively speaking. Therefore, the center of gravity of the tobacco leaf 500 after drying will move toward the petiole 520 compared to before drying.

[0021] Therefore, when the tobacco leaf 500 freely falls from the inlet 111 to the outlet 112, its petiole 520 will undergo a natural adjustment process: in the initial state, the petiole 520 and the leaf surface 510 are in the same plane, and gradually adjust to a vertical downward state during the falling process. This posture adjustment results in a significant reduction in the difference in the horizontal projection area of ​​tobacco leaves 500 of different sizes. Since the projection areas are similar, the air resistance they encounter is also similar, so it is difficult for large-sized and small-sized tobacco leaves 500 to form a significant speed difference when falling, which ultimately results in the tobacco leaves 500 falling into the feeding mechanism 400 The time interval is too short, and the dispersion effect is not ideal.

[0022] In order to solve this problem, the present application provides a posture corrector 120 in the falling channel 110 . Figure 5 The corrective effect of the posture corrector 120 on the same tobacco leaf 500 is demonstrated. When the tobacco leaf 500 falls, the petiole 520 in an inclined posture can contact the posture corrector 120 before the leaf surface 510, and the inclination of the petiole 520 is alleviated to make it flush with the leaf surface 510.

[0023] In this embodiment, if Figure 4 As shown, the posture corrector 120 is formed by bending a sheet metal structure, and in other embodiments, it can also be formed by milling or a plastic part made by injection molding. The side of the posture corrector 120 that abuts against the tobacco leaf 500 is set as an abutment surface 121, and the abutment surface 121 has an extension direction that is inclined downward. In this embodiment, the inclination angle of the abutment surface 121 is set between 40°-80°, so that the tobacco leaf 500 attached to the abutment surface 121 can continue to slide down with a straight posture as the initial posture. In other embodiments of the present application, a hinge with damping can be used between the abutment surface 121 and its supporting end (bracket, base or wall surface), so that the inclination angle of the abutment surface 121 is adjustable. In addition, in a preferred embodiment of the present application, the abutment surface 121 is set to a smooth and uniform surface, so that the tobacco leaf 500 attached to the abutment surface 121 is easier to fall off.

[0024] Based on this concept, the material used for dispersion in the present application is not limited to tobacco leaves 500, but can also be other materials with the same or similar structural characteristics as the tobacco leaves 500 after drying, that is, there are both materials with larger weight but smaller wind resistance (high-density part) and other materials with smaller weight but higher wind resistance (low-density part).

[0025] In order to improve the dispersion of tobacco leaves 500, a simple method is to increase the falling height of tobacco leaves 500 so that the falling time caused by different resistances is more discrete. To this end, it is necessary to increase the number of posture correctors 120, and arrange the increased posture correctors 120 at different absolute heights, and ensure that the preset vertical distance is maintained between the posture correctors 120 at adjacent absolute heights. The purpose of this arrangement is to prevent the tobacco leaves 500 from leaving any posture corrector 120 and entering the next posture corrector 120, so that the petiole 520 will not be completely facing downward due to the long falling stroke, that is, the tobacco leaves 500 are easy to abut against the posture corrector 120 before the petiole 520 is completely vertically downward, presenting the posture of the tobacco leaves 500 as a whole in the falling channel 110, which is repeated as follows Figure 5 As shown: straightening - sliding down - free falling - tobacco leaf 500 tilting - petiole 520 abutting - straightening.

[0026] Under this concept, there are at least two configurations of the plurality of posture correctors 120: In some implementation methods of this application, Figure 6 As shown, the posture correctors 120 with adjacent absolute heights are arranged in a step-like manner in one direction, and the abutment surfaces 121 are fixed to the base through an independently arranged bracket, and the abutment surfaces 121 extending in the same direction are on different planes with decreasing heights. After the tobacco leaf 500 enters the falling channel 110 from the feeding port 111 at the top, it falls on the first posture corrector 120 by free fall, and then slides to the abutment surface 121 of the second posture corrector 120 by free fall toward the lower right in the figure, and then falls to the abutment surface 121 of the third posture corrector 120 by free fall in the same direction to the lower right. Overall, in this embodiment, taking the figure as an example, the falling trajectory of the tobacco leaf 500 is presented as a curve extending roughly toward the lower right.

[0027] In a preferred embodiment of the present application, Figure 7 As shown, the posture correctors 120 with adjacent absolute heights are staggered, so that a plurality of abutment surfaces 121 form a zigzag structure. Specifically, the drop channel 110 is arranged as a rectangular structure surrounded by sheet metal folding, and the posture correctors 120 with adjacent absolute heights are staggered and fixed on a pair of parallel inner walls of the drop channel 110, and the abutment surfaces 121 of the posture correctors 120 with adjacent absolute heights and located above extend toward the abutment surface 121 located below. Among them, the fixing method can adopt common methods such as welding, riveting or bolt connection. When the tobacco leaf 500 enters from the feed port 111, taking the figure as an example, it falls on the first abutment surface 121, and then falls toward the lower right to the second abutment surface 121 fixed on another wall surface. The second abutment surface 121 is staggered with the first abutment surface 121, so that the tobacco leaf 500 slides toward the third abutment surface 121 located at the lower left. Overall, in this embodiment, the falling trajectory of the tobacco leaf 500 is roughly a zigzag line.

[0028] Compared with the previous embodiment, the drop channel 110 in this embodiment occupies a smaller area and does not need to separately provide a supporting structure for the abutment surface 121 , which can effectively save the volume and cost of the equipment.

[0029] In other embodiments of the present application, the above two embodiments may be combined, so that a portion of the posture correctors 120 are arranged in a stepped manner, and another portion of the posture correctors 120 are arranged in a zigzag manner, or in a zigzag and stepped manner.

[0030] It should be noted that in the above various embodiments, in order to avoid the situation where the tobacco leaves 500 do not abut against any posture corrector 120 during the falling process. The projections on the same horizontal plane between the abutment surface 121 of any posture corrector 120 and the abutment surface 121 on the posture corrector 120 at the adjacent absolute height below it have overlapping parts. In this way, taking the embodiment of the staggered arrangement of posture correctors 120 with adjacent absolute heights preferred in this application as an example: when any abutment surface 121 fixed to the side wall of the falling channel 110 extends to the center line in the thickness direction of the falling channel 110, the tobacco leaves 500 will not enter from the feed port 111 and directly fall freely along the center line to the discharge port 112 without being received by the posture corrector 120.

[0031] The present application also provides a sorting device, such as Figure 1 and Figure 8 As shown, the sorting device is formed by at least combining the above-mentioned falling dispersion mechanism 100 with the first dispersion mechanism 200 and the unloading mechanism 400.

[0032] Specifically, the first dispersing mechanism 200 includes a loading bin 210 , which is closed along the circumference and has openings 431 at the top and bottom ends, or is provided with openable and closable cover plates at the top and bottom ends, so that the operator can put tobacco leaves 500 in piles into the loading bin 210 .

[0033] To facilitate the feeding work of the operator, the upper bin 210 is placed on the ground, and its absolute height is lower than the feeding port 111 of the drop dispersing mechanism 100. In order to be able to feed the tobacco leaves 500 in the upper bin 210 into the feeding port 111 of the drop dispersing mechanism 100, a lifting track 220 is provided corresponding to the upper bin 210 and the feeding port 111 of the drop dispersing mechanism 100.

[0034] The lifting track 220 includes a track base 221, which is set on the ground and on which a belt conveyor line 222 is laid. The belt conveyor line 222 can transport tobacco leaves 500 from the upper bin 210 to the drop dispersing mechanism 100. The belt conveyor line 222 is bent to form an initial section, a lifting section, and a lowering section. The initial section and the lowering section are arranged straight and are respectively located at the bottom end of the upper bin 210 and the feed inlet 111 of the drop dispersing mechanism 100. The tobacco leaves 500 falling from the upper bin 210 into the initial section are sent to the inclined lifting section and lifted into the drop dispersing mechanism 100.

[0035] In detail, a partition 223 is vertically arranged on the belt conveyor line 222, and the length direction of the partition 223 is perpendicular to the length direction of the belt conveyor line 222. The partition 223 can stop a certain number of accumulated tobacco leaves 500 on the belt conveyor line 222 in the lifting section, and the partition 223 is evenly arranged in multiple numbers along the length direction of the belt conveyor line 222 and at preset intervals. The arrangement of multiple partitions 223 allows a stacking area for accommodating a certain number of tobacco leaves 500 to be formed between adjacent partitions 223. If the number of tobacco leaves 500 in the stacking area is too large, the excess tobacco leaves 500 will roll down in the lifting section and enter the stacking area formed by other partitions 223. In addition, in order to prevent the tobacco leaves 500 from falling from both sides of the stacking area, baffles (not shown) fixed to the track base 221 are arranged on both sides of the belt conveyor line 222.

[0036] Such arrangement enables the first dispersing mechanism 200 formed by the belt conveyor line 222 to perform the first step of dispersing the tobacco leaves 500 carried thereon, so that the tobacco leaves 500 initially enter the feed port 111 of the falling dispersing mechanism 100 in the form of small piles.

[0037] And in a preferred embodiment of the present application, the sorting device also includes Figure 1 The second dispersing mechanism 300 shown is arranged near the unloading section of the lifting track 220, and is used to receive the tobacco leaves 500 transported by the lifting track 220. The second dispersing mechanism 300 includes an inlet plate 310 arranged higher than the inlet port 111, the middle of the inlet plate 310 corresponds to the end of the unloading section of the lifting track 220, and one end of the inlet plate 310 corresponds to the inlet port 111. In addition, a vibration table 320 is installed at the bottom end of the inlet plate 310, and one end of the inlet plate 310 corresponding to the inlet port 111 is inclined toward the direction of the inlet port 111, and the inclination angle will not cause the tobacco leaves 500 falling thereon to fall into the inlet port 111 by their own gravity when the vibration table 320 is not started. After the vibration table 320 is started, the tobacco leaves 500 piled on the feed inlet 111 will be further divided into smaller tobacco leaf piles, and fall into the feed inlet 111 of the drop dispersion mechanism 100 in this form, thereby achieving the second step of dispersion before the tobacco leaves 500 enter the drop dispersion mechanism 100.

[0038] The unloading mechanism 400 is arranged corresponding to the discharge port 112 of the falling dispersion mechanism 100 , and is used to immediately transport the tobacco leaves 500 that have fallen from the discharge port 112 in a direction away from the discharge port 112 , and thus the tobacco leaves 500 with different falling times have different positions on the unloading mechanism 400 .

[0039] Specifically, Figure 8As shown, the unloading mechanism 400 includes an unloading base 410, on which a conveyor 420 is laid in the horizontal direction, and one end or the middle of the conveyor 420 is arranged corresponding to the discharge port 112 of the drop dispersion mechanism 100. The conveyor 420 can be the belt conveyor line mentioned above, or a roller conveyor line, or other equipment that can convey materials to one side.

[0040] In order to prevent the tobacco leaves 500 falling on the conveyor 420 from being skewed, that is, the length direction of the tobacco leaves 500 is greatly different from the width direction of the falling channel 110, a guide 430 is provided at one end of the conveyor 420 away from the discharge port 112 of the falling dispersion mechanism 100. Fig. 9 As shown, the guide 430 is configured as a hollow structure formed by bending a sheet metal, and has an opening 431 and an outlet 432 formed in cooperation with the conveyor 420, and a guide channel connecting the opening 431 and the outlet 432. The opening 431 is arranged toward the end of the conveyor 420, and the inner wall connecting the opening 431 and the outlet 432 has a bend, which is configured as a guide end 433. Fig.10 As shown, at any cross section passing the guiding end 433 and parallel to the width direction of the conveyor 420, the guiding channel has a width dimension A slightly larger than the width of the tobacco leaf 500, and this width dimension will correspond to the distance B between the two farthest points of the tobacco leaf 500 in the conveying direction.

[0041] When the tobacco leaf 500 with a large degree of skewness is conveyed by the conveyor 420, its front end in the conveying direction will first abut against the guiding end 433, and this end of the tobacco leaf 500 after abutment will be stopped by the guiding end 433, so the other parts of the tobacco leaf 500 will continue to move toward the guiding device 430 under the drive of the conveyor 420, thereby reducing the distance B between the two farthest points of the tobacco leaf 500 in the conveying direction, and the degree of skewness of the corresponding tobacco leaf 500 is reduced. When the distance B between the two farthest points of the tobacco leaf 500 in the conveying direction is less than the width dimension A of the guiding channel, the tobacco leaf 500 will pass through the guiding device 430 and finally enter the subsequent grading equipment.

[0042] When working: The operator puts the pile of tobacco leaves 500 into the upper bin 210 of the first dispersing mechanism 200, and the tobacco leaves 500 in the upper bin 210 fall into the lifting track 220 below and are lifted and transported toward the falling dispersing mechanism 100. During the lifting process, part of the pile of tobacco leaves 500 is stopped by the partition 223 on the belt conveyor line 222, and the other part rolls down to other accumulation areas, thereby achieving preliminary dispersion of the tobacco leaves 500.

[0043] After the tobacco leaves 500 have been initially dispersed, they reach the end of the lifting track 220 and enter the second dispersion mechanism 300 , where the vibration table 320 and the feed plate 310 perform a second dispersion step, and then enter the drop dispersion mechanism 100 for final dispersion.

[0044] After the tobacco leaves 500 fall from the second dispersing mechanism 300 into the feed port 111 of the falling dispersing mechanism 100, they will continuously restore to a straight falling state under the action of the posture corrector 120 arranged in the falling channel 110, so that tobacco leaves 500 of different sizes are subject to different air resistances, resulting in corresponding inconsistent falling speeds, thereby achieving the purpose of falling into the unloading mechanism 400 one after another.

[0045] The unloading mechanism 400 conveys the received tobacco leaves 500 toward one end, and a guide 430 is provided at the end of the conveying direction to correct the skewness of the tobacco leaves 500 so that they meet the requirements of subsequent grading equipment.

[0046] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
