Description

Technical Field

[0001] The present invention belongs to the technical field of tobacco technology. Specifically, it relates to a control method for a blending machine of tobacco flavor groups and an automatic blending machine. Background Art

[0002] Tobacco flavor is a mixture that is prepared by blending various flavors, has a certain fragrance type, and can be used for flavoring and adding materials to tobacco to improve the aroma or taste of tobacco products. Tobacco flavor is composed of various components such as sweeteners, acidulants, flavor enhancers, humectants, and mold inhibitors according to different requirements of tobacco leaf quality, flavor, etc., and is used to make the smoke soft and delicate, reduce irritation, improve aftertaste, and physical properties, etc.

[0003] Currently, cigarette production enterprises regard the technology of tobacco flavor as a key technology. Even, the flavor technology is regarded as an important technology that determines the product style and quality. The flavor formula is one of the core technical secrets of tobacco enterprises. In order to ensure the quality of flavor products and ensure stable product supply, the investment in flavor blending production equipment by each cigarette enterprise has become an important part of the major investments of the enterprise.

[0004] When the existing tobacco flavor groups are being blended, multiple simple devices are required to cooperate to complete the blending work. Manual transfer and manual batching are needed in the middle, which affects the work efficiency of batching. However, there are small-flow automatic batching devices abroad that use a conveyor chain structure to transport the blending containers. The conveyor chain shuttles between the container carrying and transferring device on the frame and the batching weighing line. When the mechanism carrying the container on the batching weighing line runs below the nozzle of the batching system, the corresponding raw materials are added. However, they are expensive and the applicability of the products is also difficult to meet the industry requirements and are not seen in application in China.

[0005] After the above equipment finishes batching, the liquid in the barrel is sufficient, and there is a risk of shaking or even jolting and tipping over, making it difficult to reciprocate smoothly and quickly between the weighing equipment and the transferring device; the inertial displacement of the barrel caused by the movement of the weighing device makes it difficult to ensure that the raw materials are reliably added to the barrel, resulting in problems such as inaccurate formula dosage, which is not conducive to the research and development and production of tobacco flavor groups.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0051] Currently, the blending of tobacco flavor groups is generally carried out in the form of manual batching, and this blending method has problems such as low work efficiency, low automation level, and difficult product quality control, and cannot meet the future needs of the tobacco industry for group blending equipment.

[0052] Embodiment 1

[0053] To solve the above problems, as Figures 1 to 8 shown, this embodiment provides a control method for a tobacco flavor group blender, and the blender includes:

[0054] A conveying device 13, which is arranged to extend in the horizontal direction or the vertical direction;

[0055] A weighing device 11, which is arranged on the conveying device 13;

[0056] A batching device 12, which is arranged on one side of the weighing device 11.

[0057] In this embodiment, the tobacco flavor is composed of a combination of various formulated fragrance raw materials. And the formulated fragrance raw materials are made by mixing various monomer fragrance raw materials in proportion.

[0058] The blender is provided with a batching line 1, a raw material transfer line 2, and a finished product discharge line 3. The batching line 1 extends in the horizontal direction or the batching line 1 extends in the vertical direction; the raw material transfer line 2 is arranged on one side of the batching line 1 and is arranged parallel to the batching line 1; the finished product discharge line 3 is arranged on one side of the batching line 1.

[0059] In this embodiment, the blender includes a weighing device 11 and a batching device 12. The weighing device 11 is arranged on the batching line 1 and is used to weigh the weight of the raw material barrel and the weight of the raw material barrel after adding raw materials, so as to control the addition process of the monomer fragrance raw materials. The batching device 12 is arranged on one side of the weighing device 11. When the raw material barrel is transferred under the batching device 12, quantitative filling is carried out according to the formula information, thereby forming the above-mentioned formulated fragrance raw materials.

[0060] The dispensing machine includes a conveying device 13, which is horizontally arranged and extends on the batching line 1. The conveying device 13 is connected to the finished product batching line 1. The raw material barrel can move on the conveying device 13 and is transferred to the batching device 12 for filling with various different monomer fragrance raw materials. After mixing, it is transported to the finished product batching line 1 to form the finished formulated fragrance raw material, thus realizing the dispensing process of the above groups.

[0061] The control method includes:

[0062] S1. Place the raw material barrel on the conveying device 13 and move it;

[0063] S2. When the raw material barrel moves to the weighing device 11, weigh the total weight of the raw material barrel;

[0064] S3. According to the total weight of the raw material barrel, judge the proportion of the ingredients to be filled, and control the batching device 12 to execute the filling program.

[0065] In the specific implementation process, when formulating the formulated fragrance raw material, the raw material barrel on the raw material transfer line 2 is placed on the batching line 1, and the raw material barrel is movable on the batching line 1. When it is detected that the raw material barrel moves to the weighing device 11, the weighing device 11 weighs the raw material barrel. Combining the weight information of various monomer fragrance raw materials required for the current formulated fragrance raw material, control the batching device 12 to add the corresponding monomer fragrance raw materials into the raw material barrel and mix them. Finally, the raw material barrel is transferred to the finished product discharge line 3 to produce the required finished formulated fragrance raw material.

[0066] With such a setting, it is possible to automatically add raw materials for dispensing according to the user's requirements for the fragrance and flavor groups. Moreover, the above dispensing process can be automatically processed, realizing the automated production of the groups, which is beneficial to meeting the different production needs of different users, helping to increase the output of the groups and improve the dispensing efficiency.

[0067] In this embodiment, the conveying device 13 may include a slide rail, which is arranged on the batching line 1 and extends along its horizontal direction. The raw material barrel can slide on the slide rail to realize the movement process of the raw material barrel, which is convenient for adding different raw materials. Moreover, the movement form using the slide rail has higher stability, avoiding the raw material barrel from tilting during the movement process and preventing the raw material from spilling.

[0068] In this embodiment, the movement form of the conveying device 13 can be adaptively adjusted according to specific usage requirements, which will not be elaborated here.

[0069] Embodiment 2

[0070] This embodiment is a further description of the above Embodiment 1.

[0071] In this embodiment, the batching device 12 includes a plurality of peristaltic pumps and batching valves, and each batching valve is correspondingly provided with a separate batching channel.

[0072] In this embodiment, the group formula generally has a small amount, the conveying pipelines are all relatively thin, and the raw materials are generally directly taken from the product packaging containers instead of being transferred to fixed raw material tanks. Therefore, it is difficult to use the gravity flow method for batching, and it is also very difficult to ensure a relatively consistent feeding flow rate by using the gravity flow method, and the production efficiency is also difficult to guarantee. In addition, some of the raw materials in the group formula have a relatively high viscosity and basically cannot flow by gravity. Therefore, a transfer pump with a small flow rate, controllable, and meeting the sanitary requirements is needed, so a peristaltic pump is used as the power source for raw material transfer.

[0073] At present, the conveying accuracy of the peristaltic pump can reach ±0.5%, and it can convey fluids with various viscosities, which is very suitable for the characteristic of a wide viscosity range of the raw materials for the tobacco essence and flavor group formula. Therefore, it can meet the needs of quantitative transfer and quantitative distribution in the formula production process. The flow rate range can be controlled by the rotation speed of the motor, which is convenient for controlling the group blending.

[0074] Specifically, the batching device 12 includes a peristaltic pump and a plurality of batching channels. The batching channels are correspondingly provided with separate batching valves, and the batching valves control the opening or closing of the batching channels.

[0075] Further, step S3 further includes: S31. Obtain the formula information of the group, and control the raw material barrel to move to the corresponding batching valve for quantitative filling.

[0076] Specifically, after the weighing device 11 weighs the raw material barrel, control the raw material barrel to be moved under the corresponding batching valve, and control the opening of the batching valve according to the weight information to add the corresponding proportion of raw materials into the raw material barrel.

[0077] Further, control the rotation speed of the motor of the peristaltic pump to adjust the flow rate of the peristaltic pump for batching and filling.

[0078] As Figure 8 shown, in this embodiment, the batching device 12 further includes an operation panel, a PLC module, a driver, and a stepping motor. The PLC module is communicatively connected to the PC terminal.

[0079] Specifically, the operation panel is provided with speed regulation, forward rotation, reverse rotation, and start / stop buttons. Select speed regulation and send an instruction to the PLC module. The PLC module sends a pulse signal to the driver, and then controls the rotation speed of the stepping motor to adjust the discharge speed of the peristaltic pump accordingly.

[0080] Further, step S31 includes: S311. According to the obtained formula information of the group, analyze and obtain the addition amount required for each batching, and control the motor of the peristaltic pump to rotate the corresponding number of turns.

[0081] Specifically, according to the obtained formulation information of the groups, the proportion of each monomer fragrance raw material is analyzed, and the corresponding number of turns of the stepper motor is controlled to achieve the control of the addition amount of each ingredient, so as to achieve the purpose of precise control.

[0082] Furthermore, the step S31 further includes: S312, controlling the forward or reverse rotation of the motor of the peristaltic pump to control the peristaltic pump for filling or cutting off the flow.

[0083] Specifically, select forward or reverse rotation, send an instruction to the PLC module, and the PLC module sends a direction signal to the driver, thereby controlling the rotation direction of the stepper motor, so as to realize the discharging or reverse suction of the peristaltic pump.

[0084] In another solution of this embodiment, the PLC module is communicatively connected to the PC terminal. Instructions can be directly issued through the PC terminal, and pulse signals or direction signals are sent through the PLC module, so as to adjust the rotation speed or rotation direction of the stepper motor, and realize the adjustment of the discharging speed of the peristaltic pump.

[0085] For the group blending process, the above control process is open-loop. Only the rotation number of the pump is used to estimate the feeding amount of the raw materials, which is not enough to meet the blending accuracy requirements of the group blending. Therefore, the weighing method is also adopted in the blending to control the amount of the formulated raw materials of the blending formula, and a closed-loop blending control system is formed with the peristaltic pump to meet the blending accuracy requirements.

[0086] Therefore, the peristaltic pump batching system has the following advantages: (1) During the process of pumping raw materials by the peristaltic pump, the raw materials flow in the hose and do not contact the pump body, avoiding the pollution of the pump body to the raw materials, reducing the influence of impurities on the product, and at the same time avoiding problems such as moldy stored materials. At the same time, the mechanical components of the pump body will not be damaged due to the corrosiveness of the raw materials. (2) The peristaltic pump does not require priming when starting, has strong self-priming ability, can generate enough vacuum suction to suck the raw materials from the raw material barrel into the hose, and the installation position of the peristaltic pump can be made flexible by adjusting the hose length. (3) The peristaltic pump has a simple structure and strong adaptability, and is suitable for transporting liquid raw materials with high viscosity and large specific gravity. (4) The pump body has no special requirements for leakage and sealing, eliminating the losses and pollution caused by raw material leakage. When the pump stops, the pressure roller itself acts as a valve to prevent backflow. (5) The peristaltic pump is sensitive in action, stable in suction and discharge, can be used for continuous pumping of raw materials, and is also convenient for automatic control. (6) The peristaltic pump has high flow accuracy, and is easy to realize micro and ultra-micro liquid pumping, adding and dripping. It is accurate in quantitative measurement during the transportation and preparation of various raw materials, simple and reliable. (7) Each raw material is independently controlled by a peristaltic pump, and the pumping of each raw material does not interfere with each other, and it is easy to synthesize solutions with various proportions.

[0087] Embodiment III

[0088] This embodiment is a further description of the above-mentioned Embodiments 1 to 2.

[0089] As Figures 2 to 7 shown, further, step S2 further includes: S21. Before detecting that the raw material barrel moves to the weighing device 11, controlling the weighing device 11 to move upward to the same horizontal height as the conveying device 13.

[0090] In a further solution of this embodiment, both ends of the weighing device 11 are respectively connected to the conveying device 13 and are arranged at the same horizontal height as the conveying device 13.

[0091] Specifically, the weighing device 11 is arranged on the batching line 1 and is arranged between the conveying devices 13. That is, both ends of the weighing device 11 are respectively connected to two parts of the conveying device 13, so that the raw material barrel can be conveyed to the weighing device 11 through the conveying device 13, realizing the weighing control process of the raw material barrel.

[0092] More specifically, the weighing device 11 is arranged at the same horizontal height as the conveying device 13, that is, the weighing device 11 is flush with the conveying device 13, in order to ensure the movement of the raw material barrel, improve the stability of its movement, prevent the raw material barrel from shaking or jolting and tipping over, and improve the conveying efficiency of the raw material barrel.

[0093] Further, the weighing device 11 can move up and down between adjacent conveying devices 13.

[0094] Specifically, the weighing device 11 is arranged between the conveying devices 13 and can move up and down. Before the raw material barrel is conveyed to the weighing device 11, control the weighing device 11 to rise, so that the weighing device 11 is flush with the conveying device 13, and the raw material barrel moves onto the weighing device 11 for weighing. According to the weighed weight information, control the batching device 12 to add the corresponding proportion of monomer fragrance raw materials to the raw material barrel. With such a setting, the weighing device 11 can move up and down, which can avoid the raw material barrel spilling onto the weighing device 11, resulting in inaccurate weighed weight and affecting the finished product quality of the formulated raw fragrance.

[0095] In this embodiment, precision control adopts the closed-loop control formula weighing production of METTLER TOLEDO high-precision small platform scales to meet the requirements of formula control precision. The weighing device 11 can be adjusted adaptively according to specific usage requirements, which will not be elaborated here.

[0096] Embodiment 4

[0097] This embodiment is a further description of the above-mentioned Embodiments 1 to 3.

[0098] As Figures 2 to 7As shown, further, the batching machine further includes a stirring device 14, and the stirring device 14 is arranged on one side of the batching device 12. The control method further includes: S4. After detecting that the raw material barrel has completed batching, control the raw material barrel to move to the stirring device 14 for stirring and mixing.

[0099] Specifically, a stirring device 14 is provided on the batching line 1. The stirring device 14 is arranged on one side of the batching device 12. After the raw material barrel is filled with different raw materials at the batching device 12, it is conveyed under the stirring device 14, and the stirring device 14 stirs and mixes various raw materials to reach the state required for the finished product's formulated fragrance raw materials.

[0100] Further, the batching machine further includes a filling device 31. The filling device 31 is arranged on one side of the stirring device 14 and is connected to the conveying device 13. The control method further includes: S5. The stirred raw material barrel is conveyed to the filling device 31 for corresponding filling according to the requirement of the finished product weight.

[0101] Specifically, a filling device 31 is provided on the finished product discharge line 3. The filling device 31 is arranged on one side of the batching device 12. The filling device 31 is connected to the conveying device 13. When the raw material barrel containing various raw materials is stirred and mixed, the raw material barrel is conveyed to the filling device 31, and the filling device 31 fills to form finished product formulated fragrance raw materials of different weights according to the required weight of the finished product to meet the needs of different users and improve applicability.

[0102] Further, the raw material transfer line 2 includes a filling device 21, and the filling device 21 is arranged at one end of the raw material transfer line 2. Before performing step S1, it includes: S0. According to the obtained weight of the required raw materials, control the seasoning device to add raw materials to the raw material barrel.

[0103] Specifically, a filling device 21 is provided on the raw material transfer line 2. The filling device 21 is arranged on one side of the raw material transfer line 2. The raw material barrel is placed under the filling device 21, and the filling device 21 adds raw materials to the raw material barrel. The raw material barrel after adding raw materials is conveyed onto the conveying device 13 and finally conveyed through the raw material transfer line 2.

[0104] In one solution of this embodiment, the raw material barrel is conveyed to the conveying device 13, including: the raw material transfer line 2 further includes an industrial robot, and the industrial robot can carry the raw material barrel after adding raw materials onto the conveying device 13, so that the raw material barrel is conveyed to the corresponding station through the raw material transfer line 2 for the process of related processes.

[0105] In another solution of this embodiment, one end of the conveying device 13 extends under the filling device 21. After the filling device 21 adds raw materials to the raw material barrel, the raw material barrel is conveyed to the corresponding station through the conveying device 13 to complete the related process flow.

[0106] In this embodiment, a shifting device is further included. The shifting device is arranged on one side of the batching device 12, and the shifting device can transfer the raw material barrel to the corresponding batching device 12 for filling.

[0107] Specifically, a shifting device is provided on the batching line 1, and the shifting device is arranged on one side of the batching device 12. When the raw material barrel is transported to the batching device 12, according to the required batching information, the shifting device grabs the raw material barrel to the lower part of the batching channel of the corresponding batching device 12 to fill the corresponding monomer fragrance raw material, so as to facilitate the setting of multiple batching channels, improve the ability of the batching device 12 to load multiple raw materials, and meet the user's needs to the greatest extent.

[0108] In the above solution, the filling volume of the peristaltic pump filling equipment can be as low as 30 μL; the filling efficiency can reach 120 bottles / minute / channel. Flow range: 0 ml / min - 1178 ml / min; maximum number of channels: 32. It supports desktop small bench-top dispensing and can be matched with automated / semi-automated filling machinery. Therefore, the above equipment can meet small-flow filling, with high enough control precision, and the effect will be better when combined with the high-precision scale of METTLER TOLEDO. The complexity of the formula can also be solved, and a maximum of 32 raw materials can be configured simultaneously.

[0109] Using the above equipment, the corresponding technical indicators can be completed. For example: (1) One-time batching amount: 5 - 20 kg; (2) Number of formula raw materials: 5 - 15; (3) Production efficiency: 80 kg / h; (4) Single production cycle: ≤50 min; (5) Group formula accuracy: higher than 5%. The above five technical indicators can all be verified in the simulated production mode. The one-time batching amount is a key design input in the product design stage. According to this design input, the volume of the batching container, the capabilities of handling and stirring equipment, etc. are designed. This indicator can be confirmed and guaranteed in the design stage and is very easy to verify the batching amount during the simulated formula production process after the product development is completed.

[0110] Therefore, the accuracy of group batching is a very important indicator. In the design stage, this technical indicator is ensured by measures such as selecting a high-precision weighing system, a closed-loop control pump, and two-stage small-flow titration batching. In the simulated production process, the dispensing accuracy of the formula can be verified by recording the weighing of each formula during feeding, and the formula accuracy can also be verified by analyzing the final composition of the product in actual production.
