However, it is obvious to those skilled in the art that the technical solution provided by the present invention can be implemented without one or more of these details.

[0059] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their combinations.

[0060] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0061] As Figures 1 to 3 shown, according to the first aspect of the embodiments of the present application, a device for non-steady small-flow material conveying is proposed, including: a base 110; a discharge conveying unit 120, the discharge conveying unit 120 includes a weighing sensor 121 and a discharge conveyor 122, the weighing sensor 121 is arranged on the base 110, and the discharge conveyor 122 is arranged on the weighing sensor 121; a material receiving conveying unit 130, the material receiving conveying unit 130 includes a material receiving conveyor 131 and a support 132, one end of the support 132 is connected to the base 110, the other end is connected to the material receiving conveyor 131, and the output end of the material receiving conveyor 131 is located at the top of the discharge conveyor 122.

[0062] The device for unsteady small-flow material conveying provided by the embodiment of the present application includes a base 110, a discharging conveying unit 120 and a receiving conveying unit 130. The discharging conveying unit 120 includes a weighing sensor 121 and a discharging conveyor 122, and the receiving conveying unit 130 includes a receiving conveyor 131 and a bracket 132. Based on this, when conveying unsteady small-flow materials, such as when conveying cut tobacco, the cut tobacco can be conveyed by the receiving conveyor 131, and the cut tobacco output via the receiving conveyor 131 can fall on the discharging conveyor 122. As the cut tobacco is continuously conveyed, the detection result of the weighing sensor 121 will change until the detection result of the weighing sensor 121 is equal to the weight required by the process. In this case, the receiving conveyor 131 can be controlled to temporarily stop, the discharging conveyor 122 can be started, and the cut tobacco can be conveyed to the next operation section, and then the receiving conveyor 131 can be started again. In this way, the stable and quantitative conveying of steady small-flow materials can be realized, the quality of the product is guaranteed, and the yield rate of the product is guaranteed.

[0063] In this technical solution, through the setting of the base 110, it is convenient for the assembly of the device for unsteady small-flow material conveying, especially for setting the device for unsteady small-flow material conveying in the process line of tobacco production. And through the setting of the bracket 132, the receiving conveyor 131 is connected to the base 110 through the bracket 132, which can modularize the device for unsteady small-flow material conveying and is convenient for the assembly and maintenance of the device for unsteady small-flow material conveying.

[0064] As Figures 1 to 3 shown, in a feasible implementation manner, the device for unsteady small-flow material conveying further includes: a first material baffle 140, and the first material baffle 140 is arranged on both sides of the discharging conveyor 122; a second material baffle 150, and the second material baffle 150 is arranged on both sides of the receiving conveying unit 130.

[0065] In this technical solution, the device for unsteady small-flow material conveying may further include a first material baffle 140 and a second material baffle 150. Such a setting is considered because the weight of the cut tobacco is light. Through the setting of the first material baffle 140, the discharging conveyor 122 can better receive the cut tobacco output via the receiving conveyor 131, which can reduce the probability of the cut tobacco falling outside the device, guarantee the cleanliness of the production space, and avoid waste of raw materials at the same time.

[0066] In this technical solution, through the setting of the second material baffle 150, the receiving conveying unit 130 can better receive the cut tobacco output from the previous operation section, which can also reduce the probability of the cut tobacco falling outside the device, guarantee the cleanliness of the production space, and avoid waste of raw materials at the same time.

[0067] It can be understood that assuming the transportation direction of the material on the receiving conveyor 131 is the first direction, then the first material baffle 140 provided on the discharging conveyor 122 will be perpendicular to or intersect with the first direction to ensure that the first material baffle 140 can block the material output via the receiving conveying unit 130.

[0068] As Figures 1 to 3 shown, in a feasible implementation, the device for transporting unsteady small-flow materials further includes: a slide rail provided on the base 110, and the bracket 132 is slidably connected to the slide rail; wherein, the slide rail includes a dovetail chute, and one end of the bracket 132 connected to the slide rail is formed with a dovetail slider.

[0069] In this technical solution, a connection method between the bracket 132 and the base 110 is further provided. A slide rail can also be provided on the base 110, and the bracket 132 is slidably connected to the base 110. Based on this, the position between the receiving conveying unit 130 and the discharging conveying unit 120 can be adjusted, which can ensure that the material output via the receiving conveying unit 130 is supplied into the discharging conveyor 122, so that the device for transporting unsteady small-flow materials can be used to transport materials with different densities, increasing the application range of the device for transporting unsteady small-flow materials.

[0070] As Figures 1 to 3 shown, in a feasible implementation, the discharging conveyor 122 includes: a first frame 1221; a first conveyor plate 1222 detachably connected to the first frame 1221 by a buckle; a first motor 1223 and a first belt 1224, the first motor 1223 is provided in the first frame 1221, the first belt 1224 is sleeved on the first conveyor plate 1222, and the first motor 1223 is used to drive the first belt 1224 to rotate.

[0071] In this technical solution, the structural composition of the discharging conveyor 122 is further provided. The discharging conveyor 122 can include a first frame 1221, a first conveyor plate 1222, a first motor 1223 and a first belt 1224. The first conveyor plate 1222 is detachably connected to the first frame 1221 by a buckle, and the first belt 1224 is sleeved on the first conveyor plate 1222. Only by starting the first motor 1223, the first belt 1224 can be driven to move relative to the first conveyor plate 1222, and the transportation of materials can be realized.

[0072] In this technical solution, the first conveyor plate 1222 is connected to the first frame 1221, providing a receiving space for the first motor 1223, facilitating the isolation of the first motor 1223 from the conveyed unsteady small-flow materials, and being able to protect the first motor 1223.

[0073] In this technical solution, the first conveyor plate 1222 is detachably connected to the first frame 1221, facilitating the maintenance and repair of the discharge conveyor 122.

[0074] As Figures 1 to 3 shown, in a feasible implementation, the receiving conveyor 131 includes: a second frame 1311; a second conveyor plate 1312, which is detachably connected to the second frame 1311 by a buckle; a second motor 1313 and a second belt 1314. The second motor 1313 is disposed within the second frame 1311, the second belt 1314 is sleeved on the second conveyor plate 1312, and the second motor 1313 is used to drive the second belt 1314 to rotate.

[0075] In this technical solution, the structural composition of the receiving conveyor 131 is further provided. The receiving conveyor 131 may include a second frame 1311, a second conveyor plate 1312, a second motor 1313, and a second belt 1314. The second conveyor plate 1312 is detachably connected to the second frame 1311 by a buckle, and the second belt 1314 is sleeved on the second conveyor plate 1312. By only turning on the second motor 1313, the second belt 1314 can be driven to move relative to the second conveyor plate 1312, and the conveying of materials can be achieved.

[0076] In this technical solution, the second conveyor plate 1312 is connected to the second frame 1311, providing a receiving space for the second motor 1313, facilitating the isolation of the second motor 1313 from the conveyed unsteady small-flow materials, and being able to protect the second motor 1313.

[0077] In this technical solution, the second conveyor plate 1312 is detachably connected to the second frame 1311, facilitating the maintenance and repair of the discharge conveyor 122.

[0078] It can be understood that the receiving conveyor 131 and the discharge conveyor 122 may adopt the same structure to improve the versatility of the equipment.

[0079] As Figures 1 to 3 shown, in a feasible implementation, the material conveying direction of the discharge conveyor 122 is different from the conveying direction of the receiving conveyor 131.

[0080] In this technical solution, a layout mode of the discharge conveyor 122 and the material receiving conveyor 131 is further provided. The material conveying direction of the discharge conveyor 122 is different from the conveying direction of the material receiving conveyor 131. With such a setting, the discharge conveying unit 120 can better receive the materials output by the material receiving conveying unit 130 and can change the conveying direction of the materials, making it easier to arrange the device for conveying non-steady small-flow materials in the production line.

[0081] As Figures 1 to 3 shown, in a feasible implementation manner, the material conveying direction of the discharge conveyor 122 is the same as the conveying direction of the material receiving conveyor 131.

[0082] In this technical solution, the material conveying direction of the discharge conveyor 122 is the same as the conveying direction of the material receiving conveyor 131. With such a setting, the structure of the device for conveying non-steady small-flow materials can be made more compact, and the floor area occupied by the device for conveying non-steady small-flow materials can be reduced.

[0083] As Figure 4 shown, according to the second aspect of the embodiments of the present application, a method for conveying non-steady small-flow materials is proposed, which is applied to the device in any of the above technical solutions. The method includes:

[0084] Step 201: Set the target discharge weight;

[0085] Step 202: Start the material receiving conveying unit and convey materials to the discharge conveyor through the material receiving conveyor;

[0086] Step 203: When the detection result of the weighing sensor reaches the target threshold, control the material receiving conveyor to stop conveying;

[0087] Step 204: Output materials to the production operation section through the discharge conveying unit;

[0088] Wherein, the target threshold is determined based on the target discharge weight.

[0089] The method for conveying non-steady small-flow materials provided by the embodiments of the present application is applied to the device for conveying non-steady small-flow materials in any of the above technical solutions. Therefore, the method for conveying non-steady small-flow materials has all the beneficial effects of the device for conveying non-steady small-flow materials in the above technical solutions.

[0090] As Figures 1 to 4As shown in the figure, the method for unsteady small-flow material transportation provided by the embodiment of the present application first sets the target discharge weight, and then starts the material receiving and conveying unit 130 to convey the material to the discharge conveyor 122 through the material receiving and conveying unit 130. When the detection result of the weighing sensor 121 reaches the target threshold, it indicates that the material on the discharge conveyor 122 has reached the target discharge weight. After that, the material receiving conveyor 131 is controlled to stop, and the material receiving conveyor 131 stops outputting the material to the discharge conveying unit 120. At the same time, the material receiving conveyor 131 can receive the material output from the previous operation section and play a role of temporary storage; then the discharge conveying unit 120 is started, and the material can be quantitatively output to the next operation section through the discharge conveying unit 120. For example, the cut tobacco can be quantitatively conveyed to the next operation section, which is convenient for the quantitative storage of the cut tobacco, convenient for counting the supply amount of the cut tobacco, and can improve the product quality.

[0091] It can be understood that the production operation section can be a process for further processing the cut tobacco or an operation section for storing the cut tobacco.

[0092] Such as Figures 1 to 4 As shown in the figure, in a feasible implementation manner, the method for unsteady small-flow material transportation further includes: when the detection result of the weighing sensor 121 reaches the target discharge weight, controlling the material receiving conveyor 131 to stop conveying; weighing the actual weight of the material on the discharge conveyor 122; determining a correction parameter based on the difference between the actual weight and the target discharge weight; and determining the target threshold based on the correction parameter and the target discharge weight.

[0093] In this technical solution, a specific method for determining the target threshold is further provided. The target threshold can be determined before the specific execution method, and there may be a certain difference between the target threshold and the target discharge weight. Specifically, the actual production state can be simulated. The material can be output from the material receiving conveyor 131 to the discharge conveyor 122. When the detection result of the weighing sensor 121 reaches the target discharge weight, the material receiving conveyor 131 is controlled to stop conveying. Then, the actual weight of the material on the discharge conveyor 122 is weighed. Since the material receiving conveyor 131 is controlled to stop conveying only when the detection result of the weighing sensor 121 reaches the target discharge weight, there may be a delay in the control. Therefore, the actual weight may be greater than the target discharge weight. In this case, the correction parameter is determined based on the difference between the actual weight and the target discharge weight, and then the target threshold is determined based on the correction parameter. When the detection result of the weighing sensor 121 reaches the target threshold, the weight of the material on the discharge conveyor 122 will be exactly equal to or very close to the target discharge weight, which can ensure that the device for unsteady small-flow material transportation can accurately output the material after combining with the method for unsteady small-flow material transportation, can ensure the accuracy of material weight statistics, improve the product quality, and is convenient for monitoring the production and processing process.

[0094] As Figures 1 to 3 shown, according to the third aspect of the embodiments of the present application, a tobacco production system is provided, including: a supply unit; a device for non-steady small-flow material transportation as described in any of the above technical solutions, and the supply unit is connected to a material receiving and transportation unit 130; a storage unit, and an output end of an outgoing material transportation unit 120 is connected to the storage unit.

[0095] Since the tobacco production system provided by the embodiments of the present application includes a device for non-steady small-flow material transportation as described in any of the above technical solutions, the tobacco production system has all the beneficial effects of the device for non-steady small-flow material transportation in the above technical solutions.

[0096] The tobacco production system provided by the embodiments of the present application includes a supply unit, a device for non-steady small-flow material transportation, and a storage unit. Based on this, during the working process, the supply unit can output cut tobacco, and the cut tobacco can be quantitatively output to the storage unit once through the device for non-steady small-flow material transportation. The storage unit can store the cut tobacco. By only counting the output times of the cut tobacco, the total weight of the cut tobacco can be counted, which is convenient for monitoring the production process of tobacco preparation.

[0097] In some examples, the tobacco production system may further include multiple waste tobacco machines and multiple cut tobacco foreign matter removal machines. The multiple waste tobacco machines are used to process unqualified cigarettes to separate and obtain cut tobacco. The output end of one waste tobacco machine is connected to the cut tobacco foreign matter removal machine, and the output end of the cut tobacco foreign matter removal machine is connected to the supply unit. The supply unit can then output cut tobacco to the device for non-steady small-flow material transportation. The device for non-steady small-flow material transportation can quantitatively output the output cut tobacco, which is convenient for counting the weight of waste tobacco cut tobacco and for counting the yield rate of tobacco product production and processing. Then the cut tobacco is stored in the storage unit, and the cut tobacco in the storage unit can be used to process cigarettes.

[0098] In a feasible implementation manner, the tobacco production system further includes: a sampling inspection unit, and another output end of the outgoing material transportation unit 120 is connected to the sampling inspection unit.

[0099] In this technical solution, the structural composition of the tobacco production system is further provided. The tobacco production system may further include a sampling inspection unit. When the outgoing material conveyor 122 of the outgoing material transportation unit 120 outputs along the first direction, the cut tobacco will be output to the storage unit. When the outgoing material conveyor 122 outputs along the second direction, the cut tobacco will be supplied to the sampling inspection unit. Through the setting of the sampling inspection unit, the quality of the cut tobacco can be sampled and inspected, which can further ensure the quality of tobacco products.
