Description

Technical Field

[0001] This utility model relates to the field of material handling device technology, and in particular to a tobacco leaf bundling device. Background Technology

[0002] The tobacco-making process generally includes tobacco leaf harvesting, processing, and rolling into tobacco products. After harvesting, the tobacco leaves are wrapped in burlap and packaged into tobacco bales for easy transportation and storage. In the processing step, the tobacco bales are first opened to expose the pile of tobacco leaves inside. The tobacco leaves are then separated and sorted according to their parts, colors, maturity, and other characteristics. They are then subjected to subsequent processing such as drying, smoking, curing, and sun-drying to ultimately form the raw tobacco leaves.

[0003] In existing technologies, the general process for separating and unbundling tobacco leaves is as follows: a forklift transports tobacco leaf bales to the unbundling station, workers unpack the bales, and separate the tobacco leaves from each other. This process requires multiple workers and takes a long time, resulting in high efficiency and low productivity. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] The present invention will now be described in detail.

[0040] The tobacco-making process generally includes tobacco leaf harvesting, processing, and rolling into finished tobacco products. After harvesting, the tobacco leaves are wrapped in burlap and packaged into tobacco bales for easy transportation and storage. In the processing step, the tobacco bales are first opened to expose the piles of tobacco leaves inside. The tobacco leaves are then separated and sorted according to their parts, colors, sizes, maturity, and other characteristics. They are then subjected to four processing steps: air-drying, smoking, curing, and sun-drying. This process involves the tobacco leaves going through four stages: wilting, yellowing, color fixing, and drying, forming the raw tobacco leaves. Based on the temperature and humidity requirements of subsequent processes, the leaves, stems, and spices are mixed according to the formula and cut into shreds. The shredded tobacco leaves are then re-moistened and dried (re-cured).

[0041] In existing technology, when purchasing tobacco bales wrapped in burlap shavings from local tobacco stations, the burlap shavings need to be unwrapped and loosened before the tobacco can be processed into tobacco products. The specific process is generally as follows: warehouse staff stack the tobacco bales onto pallets, multiple forklifts transport the tobacco bales to the loosening station for buffering, and the staff at the loosening station unwrap the tobacco bales and, according to the tobacco sorting speed at the back end, lift the stacked tobacco bales to the loosening table in a timely manner to unwrap the burlap shavings and loosen the bales, so that each tobacco leaf is separated from the others.

[0042] Clearly, for large-scale, automated tobacco production, the existing loose-bundle system has many drawbacks: First, for large-scale production processes, manual loosening is inefficient, requiring two to three workers to unpack and loosen each tobacco bale, which is time-consuming, labor-intensive, and costly; Second, to improve production efficiency, multiple loosening stations are usually used to unpack and loosen the tobacco bales simultaneously, but currently, tobacco bales are transported to the loosening station by forklift, resulting in a complex and crowded production site with high safety risks.

[0043] Therefore, it is essential to develop a tobacco leaf sorting device that can effectively reduce the labor intensity of workers, lower labor costs, and ensure uniform sorting of tobacco leaves.

[0044] This utility model addresses the problems existing in the prior art by proposing a tobacco leaf loosening device. The tobacco leaf loosening device includes: a feeding mechanism for conveying a tobacco leaf pile to a support plate; a dispersing mechanism including a vibrating device and a support plate, the support plate being configured to vibrate under the drive of the vibrating device, thereby dispersing the tobacco leaf pile on the support plate; and a separating mechanism adjacent to the dispersing mechanism, the separating mechanism including a first gripper and a first conveyor belt, the first gripper being disposed on the surface of the first conveyor belt and capable of grasping or releasing the dispersed tobacco leaves; wherein, the support plate has an opening on the side facing the separating mechanism, and the first gripper contacts and grasps the dispersed tobacco leaves through the opening, the tobacco leaf pile comprising multiple tobacco leaves.

[0045] Because of the vibrating support plate, the tobacco leaf pile is initially dispersed by vibration, making the arrangement of the tobacco leaves more loose. With a first gripper and a first conveyor belt capable of gripping or releasing the tobacco leaves, a single tobacco leaf can be independently gripped from the initially dispersed pile. The first conveyor belt then separates the individual leaves from the others. The first conveyor belt drives the first gripper in a cyclical operation, enabling continuous loosening of the pile. This highly automated process saves significant manpower, and the controllable and constant work cycle helps improve the efficiency of loosening and separating the tobacco leaves, saving time and effort.

[0046] The following is combined with Figures 1 to 6 This invention describes a tobacco leaf bundling device.

[0047] An embodiment of this utility model provides a tobacco leaf bundling device, such as... Figure 1 and Figure 6 As shown, the device includes: a feeding mechanism 10 for conveying a pile of tobacco leaves to a support plate 22; a dispersing mechanism 20, including a vibration device 21 and a support plate 22, the support plate 22 being configured to vibrate under the drive of the vibration device 21, the pile of tobacco leaves on the support plate 22 being dispersed under vibration; and a separation mechanism 30, adjacent to the dispersing mechanism 20, the separation mechanism 30 including a first gripper 31 and a first conveyor belt 32, the first gripper 31 being disposed on the surface of the first conveyor belt 32, the first gripper 31 being able to grab or release the dispersed tobacco leaves; wherein, the support plate 22 has an opening 221 on the side facing the separation mechanism 30, the first gripper 31 contacting and grabbing the dispersed tobacco leaves through the opening 221, the pile of tobacco leaves including multiple tobacco leaves.

[0048] The tobacco leaf unpacking device includes a feeding mechanism 10, a dispersing mechanism 20, and a separating mechanism 30. The dispersing mechanism 20 is adjacent to the feeding mechanism 10, and the separating mechanism 30 is adjacent to the dispersing mechanism 20. The feeding mechanism 10 provides a tobacco leaf pile to the separating mechanism 30, which fluffs the tobacco leaf pile and separates each tobacco leaf in the fluffed tobacco leaf pile from each other.

[0049] The feeding mechanism 10 refers to the mechanism used to convey tobacco leaf stacks to the carrier plate 22 of the dispersing mechanism 20. The feeding mechanism 10 continuously supplies tobacco leaf stacks to the carrier plate 22, enabling the tobacco leaf unpacking equipment to continuously perform separation operations.

[0050] The feeding mechanism 10 can be a conveyor line such as a conveyor belt, or a conveyor trolley, etc. This utility model does not limit this. Figure 1 The example of a conveyor belt is given.

[0051] Furthermore, an infrared sensor can be installed on the feeding mechanism 10 to determine the position of the tobacco pile relative to the feeding mechanism 10.

[0052] The dispersing mechanism 20 refers to the mechanism used to fluff up the tobacco pile.

[0053] The dispersing mechanism 20 includes a vibration device 21 and a support plate 22. The vibration device 21 provides continuous vibration, and the support plate 22 supports the tobacco pile. The vibration device 21 abuts against or connects to the support plate 22, and the vibration of the vibration device 21 is transmitted to the tobacco pile through the support plate 22, thus loosening the tobacco pile.

[0054] Specifically, the dispersing mechanism 20 also includes a base, which is placed on the ground or a workbench. A vibration device 21 is mounted on the base. A support plate 22 is disposed at the vibration output end of the vibration device 21. The support plate 22 has a bottom wall for support and side walls for limiting movement; tobacco leaves are stacked on the bottom wall, and the side walls prevent the tobacco leaves from being shaken out of the support plate 22 during vibration.

[0055] An opening 221 is provided on the side wall of the support plate 22, facing the separation mechanism 30. Under the action of vibration, the tobacco leaves are piled up loosely and evenly on the support plate 22, and some tobacco leaves are exposed from the opening 221.

[0056] For example, the vibration device 21 is a magnetic vibrator. The magnetic vibrator works on the principle of electromagnetic induction. When the electromagnetic coil is energized, an electromagnetic field is generated. The magnetic field causes the connected magnetic core and the vibrating spring to generate tension, which causes the vibrating spring to deform and generate high-frequency vibration, thereby driving the bearing plate 22 to move in multiple degrees of freedom.

[0057] When the tobacco leaves are oily and highly adhesive, the binding force between the leaves is strong. The manual tearing action simulated by the separation mechanism 30 alone is insufficient to completely separate the tobacco bundles. The dispersing mechanism 20 is quite effective in dealing with the extreme case of clump-forming tobacco. Therefore, the raw tobacco needs to be fluffed up at the beginning of the loosening process to ensure the smooth implementation of the subsequent loosening process.

[0058] The separation mechanism 30 refers to a mechanism capable of separating individual tobacco leaves from the tobacco pile.

[0059] The separating mechanism 30 includes a first gripper 31 and a first conveyor belt 32. The first gripper 31 has two states: closed and open. In the closed state, the first gripper 31 can grasp tobacco leaves; in the open state, the first gripper 31 can release tobacco leaves. The extension direction of the first conveyor belt 32 is parallel to the opening direction of the support plate 22. The surface of the first conveyor belt 32 is provided with the first gripper 31. When the first conveyor belt 32 is running, it drives the first gripper 31 to alternately move closer to the support plate 22 and away from the support plate 22.

[0060] In operation, the first conveyor belt 32 moves the first gripper 31 closer to the support plate 22 until the first gripper 31 faces the opening 221, where it grabs the exposed tobacco leaves. The first conveyor belt 32 then moves the gripper 31 away from the support plate 22, and after reaching a designated position, it releases the tobacco leaves, completing the separation of loose tobacco leaves. The cooperation between the first conveyor belt 32 and the first gripper 31 simulates the action of manual tearing.

[0061] Furthermore, multiple first grippers 31 can be spaced along the first conveyor belt 32. The first conveyor belt 32 rotates periodically, thereby driving each first gripper 31 to pass through the opening 221 in sequence, achieving uninterrupted hand gripping.

[0062] The tobacco leaf unpacking device provided by this utility model has a vibrating support plate 22, which allows the tobacco leaf pile to be initially dispersed under vibration, making the arrangement of the tobacco leaves more loose. Because it has a first gripper 31 capable of gripping or releasing tobacco leaves and a first conveyor belt 32, it can independently grab a single tobacco leaf from the initially dispersed pile. The first conveyor belt 32 then separates the individual tobacco leaves from the others. The first conveyor belt 32 drives the first gripper 31 in a cyclical operation, enabling continuous unpacking. This device has a high degree of automation, saves a significant amount of manpower, and provides a controllable and constant operating cycle, thus improving unpacking efficiency and saving time and effort.

[0063] In some embodiments, the dispersing mechanism 20 further includes a driving device and a dispersing element; the dispersing element is configured to pass through the support disk 22 under the drive of the driving device for dispersing tobacco leaves through a pile or pile.

[0064] The dispersing mechanism 20 also includes a drive unit and a dispersing element. The dispersing element can move under the drive of the drive unit, causing it to periodically pass through the tobacco pile on the support plate 22. The dispersing element's striking and agitating action on the tobacco pile makes it more fluffy.

[0065] Furthermore, the dispersing component can have a blade, which cuts the tobacco leaves each time it passes through the tobacco pile, thus separating the tobacco leaves from each other and reducing the size of the tobacco leaves, making it easier for subsequent processing.

[0066] In some embodiments, such as Figure 1 and Figure 4 As shown, the driving device includes a first rotary motor (not shown in the figure), and the dispersing component includes a dispersing blade 23. One end of the dispersing blade 23 is connected to the driving end of the first rotary motor. The dispersing blade 23 is located at the opening 221 of the support plate 22, and the rotation plane of the dispersing blade 23 is perpendicular to the direction of the opening 221.

[0067] The dispersing component includes a dispersing blade 23, which has a cutting edge. Along the direction of gravity, the dispersing blade 23 is positioned above the support plate 22 and at the opening 221 of the support plate 22. One end of the dispersing blade 23 is connected to the drive end of a first rotary motor, which faces the opening 221, causing the plane of rotation of the dispersing blade 23 to be perpendicular to the direction of the opening 221. The other end of the dispersing blade 23 periodically passes through the tobacco leaves at the opening 221 during rotation.

[0068] In actual use, by controlling the running speed of the first conveyor belt 32 and the rotation speed of the first rotary motor, the working rhythm of both can be kept constant and coordinated. After the first gripper 31 grabs the tobacco leaves and moves them a certain distance, some tobacco leaves may be too long and cross the first gripper 31 and the carrier plate 22. This will affect the gripping action of the next gripper. The first rotary motor can drive the dispersing blade 23 to cut the excessively long tobacco leaves, so that the length of each tobacco leaf grabbed and transported by the first gripper 31 does not exceed a certain value, thereby ensuring the stability and reliability of the overall operation.

[0069] In some embodiments, such as Figure 1 and Figure 4 As shown, the dispersing mechanism 20 also includes a baffle 24, which is located in the middle of the opening 221. A first rotary motor is located on the baffle 24, and two dispersing blades 23 are located on both sides of the baffle 24.

[0070] The dispersing mechanism 20 also includes a baffle 24, which has a wall surface that contacts and blocks the tobacco pile. The baffle 24 is located in the middle of the opening 221, dividing the opening 221 into two. Two dispersing blades 23 are located on both sides of the opening 221 of the baffle 24, so that the opening 221 corresponds to the dispersing blade 23 one-to-one.

[0071] One first rotary motor can be installed on the baffle 24, which can drive two dispersing blades 23 at the same time, so that the dispersing blades 23 rotate simultaneously; or two first rotary motors can be installed on the baffle 24, with each first rotary motor corresponding to a dispersing blade 23, and the corresponding first rotary motor independently drives the dispersing blade 23 to rotate.

[0072] The first rotary motor has a first gear at its output end, and one end of the dispersing blade 23 is coaxially connected to a second gear. The second gear meshes with the first gear, thereby enabling the first rotary motor to drive the dispersing blade 23 to rotate.

[0073] Furthermore, multiple baffles 24 are provided, which are evenly distributed at the opening 221, dividing the opening 221 into multiple independent openings. Multiple dispersing blades 23 are respectively arranged corresponding to the openings 221. A first rotary motor is arranged between two adjacent dispersing blades 23, and / or each dispersing blade 23 is mounted on a first rotary motor.

[0074] In an optional embodiment, the support plate 22 has at least two openings 221 on its sidewall facing the separation mechanism 30, with a sidewall separating adjacent openings 221. The first rotary motor is disposed on the sidewall near the separation mechanism 30.

[0075] In some embodiments, a first gripper group is provided corresponding to the dispersing blade 23, and the first gripper group includes a plurality of first grippers 31 arranged along the extension direction of the first conveyor belt 32.

[0076] Multiple first grippers 31 are arranged along the first conveyor belt 32, with each first gripper 31 spaced apart from the others by a certain distance. The multiple first grippers 31 arranged along the extension direction of the first conveyor belt 32 are considered as a first gripper group. During the cyclic operation of the first conveyor belt 32, the first grippers 31 in the first gripper group pass through the opening 221 in sequence.

[0077] The first gripper group is set corresponding to the opening 221. When there are multiple openings 221, the first gripper group is set on the first conveyor belt 32 for each opening 221. The first gripper groups can be set symmetrically.

[0078] In an optional embodiment, the first conveyor belt 32 is provided corresponding to the opening 221. When multiple openings 221 are provided, a first conveyor belt 32 is provided for each opening 221, and each first conveyor belt 32 is provided with a first gripper group.

[0079] For example, the first conveyor belt 32 is a tracked mechanical structure as shown in the figure.

[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, the feeding mechanism 10 includes a conveyor line 11 and a handling device 12; the conveyor line 11 is used to convey tobacco leaf piles to the handling device 12; the handling device 12 includes a second gripper 121 and a moving component 122, the second gripper 121 is connected to the moving component 122, and the second gripper 121 is capable of gripping or releasing the tobacco leaf pile; wherein, the second gripper 121 is configured to be able to rise and fall under the drive of the moving component 122 and move between the conveyor line 11 and the carrier plate 22.

[0081] Taking a linear conveyor line as an example, the tobacco leaf pile is placed on the conveyor line 11 and moves together with the conveyor line 11. A robot arm can be set up on the upstream side of the conveyor line 11 to load the tobacco leaf pile onto the conveyor line 11; alternatively, a loading station can be set up on the upstream side of the conveyor line 11, where workers unpack the tobacco leaf bales to form a tobacco leaf pile.

[0082] The conveying device 12 includes a second gripper 121 and a moving assembly 122. The first gripper 121 has two states: closed and open. In the closed state, the second gripper 121 can grasp the tobacco pile; in the open state, the second gripper 121 can release the tobacco pile. The moving assembly 122 is configured to drive the second gripper 121 to rise and fall and move between the conveyor line 11 and the carrier plate 22.

[0083] In one embodiment, the moving component 122 can be a highly flexible robotic arm, such as a six-axis robot; of course, other structures capable of performing the functions of the moving component 122 in the embodiments of this utility model can also be used.

[0084] In use, the moving component 122 drives the second gripper 121 to move above the conveyor line 11. When the tobacco pile moves below the second gripper 121 along with the conveyor line 11, the moving component 122 drives the second gripper 121 to descend, and the second gripper 121 grabs the tobacco pile. The moving component 122 drives the second gripper 121 to rise, moving it above the support tray 22, where the second gripper 121 releases the tobacco pile, causing it to fall into the support tray 22.

[0085] Furthermore, a weighing component is installed on the second gripper 121 or the moving component 122, allowing the second gripper 121 to collect the weight information of the tobacco pile when gripping it. Based on this weight information, statistical data such as production flow and efficiency can be calculated. Engineering managers can then use this statistical data to monitor, control, and manage the production site. Simultaneously, in subsequent research, the analysis of abnormal data can be used to optimize and modify corresponding process equipment, thereby improving production capacity.

[0086] In some embodiments, the tobacco leaf pile conveyed by the conveyor line 11 is supported in the feeding tray; the handling device 12 also includes a rotating component (not shown in the figure), and the second gripper 121 is connected to the moving component 122 through the rotating component. The second gripper 121 can grip or release the feeding tray; wherein, when the moving component 122 drives the second gripper 121 to move to the support tray 22, the rotating component flips the second gripper 121 to tilt the tobacco leaf pile on the feeding tray onto the support tray 22.

[0087] To reduce spillage, a feeding tray can be placed on the conveyor line 11, and the tobacco leaves can be piled in the feeding tray for conveying. The handling device 12 also includes a rotating component, and the second gripper 121 is connected to the moving component 122 through the rotating component. The second gripper 121 is configured to rotate under the drive of the rotating component.

[0088] In use, the moving component 122 drives the second gripper 121 to move above the conveyor line 11. When the feeding tray carrying the tobacco pile moves below the second gripper 121 along the conveyor line 11, the moving component 122 drives the second gripper 121 to descend, and the second gripper 121 grabs the feeding tray. The moving component 122 drives the second gripper 121 to rise, moving the second gripper 121 above the support tray 22. The rotating component drives the second gripper 121 to rotate, thereby causing the feeding tray to flip, causing the tobacco pile to tilt into the support tray 22. The rotating component drives the second gripper 121 to reset, the moving component 122 moves the second gripper 121 back to the conveyor line 11, the second gripper 121 releases the feeding tray, and the feeding tray leaves with the conveyor line 11.

[0089] In some embodiments, the moving component 122 includes a bracket, a moving frame, a slide rail, a sliding seat, a first motor, and a second motor; the first motor is mounted on the bracket, the moving frame is connected to the drive end of the first motor and is capable of moving up and down, the slide rail is disposed on the moving frame and spans the conveyor line 11 and the carrier plate 22, the sliding seat is disposed on the slide rail in a manner that allows it to move along the slide rail, the sliding seat is connected to the drive end of the second motor, and the second gripper 121 is connected to the sliding seat through a rotating component.

[0090] The moving component 122 includes a bracket, a moving frame, a slide rail, a sliding seat, a first motor, and a second motor. The bracket can be fixed to the ground or a workbench. The first motor is mounted on the bracket, and the drive end of the first motor is connected to the moving frame. Driven by the first motor, the moving frame can reciprocate along the direction of gravity, i.e., lift and lower.

[0091] The movable frame is equipped with a slide rail, which is located above and spans the conveyor line 11 and the support plate 22. A sliding seat is slidably connected to the slide rail. The frame is also equipped with a second motor, the drive end of which is connected to the sliding seat, allowing the sliding seat to reciprocate along the slide rail under the drive of the second motor. The sliding seat is equipped with a rotating component, and a second gripper 121 is connected to the rotating component.

[0092] In some embodiments, the rotating assembly includes a second rotating motor, and the second gripper 121 is connected to the output end of the second rotating motor.

[0093] In some embodiments, the rotating assembly includes a second rotary motor, an output gear and a transmission gear meshing with each other; the output end of the second rotary motor is connected to the output gear, the transmission gear is rotatably connected to the sliding seat, and the transmission gear is connected to the second gripper 121.

[0094] The rotating assembly includes a second rotary motor, an output gear, and a transmission gear. The second rotary motor is mounted on a sliding base, and its output end is coaxially connected to the output gear. The transmission gear is mounted on the sliding base and meshes with the output gear. The second gripper 121 can be coaxially connected to the transmission gear or eccentrically connected to it, allowing the second gripper 121 to rotate with the transmission gear.

[0095] In some embodiments, such as Figure 5 As shown, the separation mechanism 30 also includes a second conveyor belt 33, which is located below the first conveyor belt 32 and is disposed at least on the downstream side of the first conveyor belt 32.

[0096] The separation mechanism 30 also includes a second conveyor belt 33. In the same projection plane perpendicular to the direction of gravity, the projections of the first conveyor belt 32 and the second conveyor belt 33 at least partially overlap, and the overlapping portion of the first conveyor belt 32 relative to the second conveyor belt 33 is at least located downstream of the first conveyor belt 32. The tobacco leaves conveyed by the first conveyor belt 32 fall onto the second conveyor belt 33 from the downstream side.

[0097] The side of the first conveyor belt 32 closest to the carrier plate 22 is the upstream side, and the side furthest from the carrier plate 22 is the downstream side.

[0098] In some embodiments, such as Figure 6 As shown, the separation mechanism 30 also includes a storage box 40 for storing the separated tobacco leaves.

[0099] The storage box 40 has an opening on one side, through which the separated tobacco leaves enter. The storage box 40 can be positioned downstream of the second conveyor belt 33, so that the separated tobacco leaves are transported into the storage box 40 along with the second conveyor belt 33. Alternatively, a transfer device for handling can be provided between the storage box 40 and the second conveyor belt 33.

[0100] For further details, please refer to [link / reference]. Figure 6 The separation mechanism 30 also includes a compaction device 50, which has a compaction element that can move along the direction of gravity. The compaction element can enter or exit the storage box 40 from the opening to compact the tobacco leaves in the storage box 40. Optionally, the compaction element has rollers that can rotate and move from one side of the storage box 40 to the other, thereby compacting the tobacco leaves. This increases the loading capacity of a single storage box 40, thereby improving warehouse utilization. Compared with manual compaction, the compaction degree is higher, improving warehouse utilization, saving labor costs, and increasing production profits.

[0101] In this utility model, the feeding mechanism 10, the dispersing mechanism 20, and the separating mechanism 30 work together and are interconnected, forming an integrated system of warehouse discharge, loose tobacco bundles and feeding tray recycling. While achieving the goals of reducing the labor intensity of workers, lowering labor costs, and building an intelligent production management model, it also fully ensures the uniformity of loose bundles and the looseness rate of tobacco leaves, reduces the difficulty of production process control, and improves production capacity.

[0102] The separation mechanism 30 in this utility model can also work in conjunction with the compaction device 50 to form a complete production mode of feeding loose bundles and automatic packing, which effectively improves the production efficiency of loose bundles and other processes in the factory.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
