Description

Technical Field

[0001] The invention belongs to the technical field of tobacco shred processing, and in particular relates to a method and a system for marking, identifying and transmitting information on cut tobacco blocks. Background Art

[0002] In the feeding section of the existing tobacco silk production line, the raw materials are carton cigarette packs sent from the leaf beating and re-drying line. After the packaging of the carton cigarette packs is removed by the pack opener, a slicer or a slicing machine is used to cut the dense cigarette packs into tobacco blocks to meet the size required for subsequent processing.

[0003] At present, the better-designed electronic control device for silk-making wire adopts corresponding technical means to track the information of cigarette packs to the slicer or slicing machine. However, on the one hand, after the carton cigarette pack is opened and the packaging is removed, the material information (such as origin, grade, etc.) is lost along with the packaging; on the other hand, after the cigarette pack is cut into cigarette blocks by the slicer or slicing machine, the information is completely lost because the cigarette blocks need to be lined up one by one on the downstream belt conveyor, which cannot be identified by the existing technical means. The electronic control device cannot identify the cut cigarette blocks, and thus cannot transmit the information of the cigarette blocks to the subsequent processing equipment (such as the drum-type leaf rehumidification machine). The formula of a certain brand of a cigarette factory generally contains different weights of tobacco leaves of different origins, different grades and other specifications. For example, when processing brand X cigarettes, its formula contains 10% Yunnan Honghe C1F, 10% Yunnan Honghe C3F, 20% Yunnan Yuxi CXF, 20% Fujian Sanming C4F, 20% Guizhou Meitan C1F, 10% Guangxi Wuming C2F, and 10% Guangdong Shaoguan C4F. These different tobacco leaves have different mechanical qualities and inherent physical and chemical qualities, such as the material's processing resistance and hygroscopicity. In actual production, these different tobacco leaves are fed according to their component proportions, and the processing procedures such as rehumidification and feeding are carried out in sequence, and finally mixed in the leaf storage cabinet to form a brand. Since the existing technology lacks the tracking of different tobacco leaf information, the drum leaf rehumidification machine cannot process a certain specification of tobacco leaves in a targeted manner according to its properties.

[0004] In view of this, it is necessary to provide a method and system for marking, identifying and transmitting information of cut tobacco blocks, so as to identify the information of incoming tobacco blocks and carry out targeted processing using corresponding processing parameters according to their properties, which is conducive to maintaining or stimulating the aroma substances in tobacco leaves, highlighting their flavor style and obtaining better processing effects. Summary of the invention

[0005] The invention aims to solve the problem of information transmission of cut tobacco blocks from a slicer or a slicing machine to a drum-type blade rehumidifying machine.

[0006] In view of the deficiencies existing in the above-mentioned background technology, the invention object of the present application is to provide a method and system for marking, identifying and transmitting information of the cut tobacco blocks, so as to identify the cut tobacco blocks and transmit their information to downstream processing equipment, so that the downstream processing equipment can perform targeted processing on the tobacco blocks according to the tobacco block information.

[0007] In order to achieve the invention purpose of this application, the present invention adopts the following technical solutions:

[0008] A method for marking, identifying and transmitting information of a cut cigarette block, comprising:

[0009] The method uses a visual recognition and laser engraving device, a visual recognition device, and an electronic control device; the visual recognition and laser engraving device is installed above a belt conveyor below a discharging port of a slicer or a slicing machine; the visual recognition device is installed above an electronic belt scale in front of a drum-type blade rehumidifying machine; and the electronic control device is respectively connected to the visual recognition and laser engraving device, the visual recognition device, and a production line control device.

[0010] The visual recognition and laser engraving device identifies the range of the cigarette block and engraves a frame slightly smaller than the range on the surface of the cigarette block, and numbers, characters or patterns are engraved in the frame. The frame on the cigarette block is the dividing line of the cigarette block, and the numbers, characters or patterns in the frame are the codes of the formula components of different origins, different grades and different water absorption. The visual recognition and laser engraving device can also only engrave numbers, characters or patterns on the surface of the cigarette block, such as: 88 or 888 or AA or ABC or QR code, etc.

[0011] The electronic control device transmits the identified information to the production line control device.

[0012] The method comprises the following steps:

[0013] (1) Relevant process preparations must be made in advance, such as analyzing the formula composition of the brand, pre-compilation of different processing parameter rules corresponding to different materials, and pre-coding of formula materials of different origins, grades, and water absorption according to brand formula and other information. For example, 001 or AA or a cat pattern can represent Yunnan Honghe C3F, 002 or ABC or a dog pattern can represent Yunnan Yuxi CXF, 003 or AC or a horse pattern can represent Guizhou Meitan C3F. For another example, if a two-digit code is used, the brand or specification can represent 00-99, a total of 100 specifications; if a three-digit code is used, the brand or specification can represent 000-999, a total of 1000 specifications. For some specifications with a small total amount of the formula, due to their small amount, they cannot be processed separately. According to their properties, they can be processed with the same processing parameters as specifications with similar properties, that is, the same code is used for both;

[0014] (2) After slicing, the tobacco block is visually identified by a visual recognition and laser engraving device, and information is engraved on the surface of the cut tobacco block using a laser. Specifically, the visual recognition and laser engraving device identifies each tobacco block, visually determines its range, and engraves a frame slightly smaller than its range on the tobacco block, and engraves numbers, characters, or patterns in the frame. The frame on the tobacco block is the dividing line of the tobacco block, and the numbers, characters, or patterns in the frame are the codes of the formula components of different origins, different grades, and different water absorption;

[0015] (3) The cigarette block is transported by the belt conveyor to the top of the electronic belt scale. The visual recognition device identifies the frame and code laser engraved on the surface of the cigarette block, and the electronic control device interprets the brand or specification represented by the corresponding code. At the same time, the range of the cigarette block is determined based on the frame on the cigarette block, and the time it will enter the drum is calculated based on the running speed of the electronic belt scale;

[0016] (4) The electronic control device uses the corresponding processing parameters to control the equipment to perform moisture rehydration according to the decoded information of the tobacco block. For example, code 16 means that the tobacco block is low-grade lower tobacco from a certain place, and its hygroscopicity is relatively weak. Therefore, during the processing period of this kind of material, the electronic control device needs to appropriately increase the temperature and humidity in the cylinder, increase the injection amount of humidifying water, and promote the material's absorption of humidifying water. For another example, code 22 means that the tobacco block is low-grade tobacco from a certain place, and its quality is relatively poor. Therefore, during the processing period of this kind of material, the electronic control device needs to appropriately increase the processing temperature to temper it, remove its green impurities, and promote the conversion of aroma substances;

[0017] (5) Better processing quality can be achieved by carrying out targeted processing on materials with different origins, grades, water absorption and qualities.

[0018] Furthermore, by marking and identifying the information of the cut tobacco blocks, the information is transmitted to the downstream drum-type blade rehumidifier, so that the downstream processing equipment can carry out targeted processing of the tobacco blocks according to the tobacco block information. During the production process, the appropriate drum speed is selected according to the processing resistance of the incoming materials to reduce crushing.

[0019] Furthermore, by marking and identifying the information of the cut tobacco blocks, the information is transmitted to the downstream drum blade rehumidification machine, so that the downstream processing equipment can carry out targeted treatment of the tobacco blocks according to the tobacco block information. During the production process, according to the hygroscopicity of the incoming materials, humidifying water is applied in a targeted manner to control the moisture content of the material outlet within a better range, thereby improving the processing quality.

[0020] Furthermore, by marking and identifying the information of the cut tobacco blocks, and transmitting the information to the downstream drum blade rehumidifier, the downstream processing equipment can carry out targeted processing of the tobacco blocks according to the information of the tobacco blocks. In the production process, according to the intrinsic physical and chemical quality of the incoming materials, the appropriate processing temperature is used to achieve the conditioning of the corresponding incoming materials. It is avoided that the same processing temperature is used for different materials, resulting in incomplete removal of green impurities in low-quality materials, and excessive volatilization of aroma substances in high-quality materials, which affects the taste of cigarettes.

[0021] A computer-readable storage medium stores a computer program, which is executed by a processor to implement the steps of a method for marking, identifying and transmitting information of cut tobacco blocks according to the present invention.

[0022] A system for marking, identifying and transmitting information on cut tobacco blocks, the system comprising a visual recognition and laser engraving device 6, a visual recognition device 7 and an electronic control device 8; the visual recognition and laser engraving device 6 is installed above a belt conveyor 2 below a discharge port of a slicer or slicer 1; the visual recognition device 7 is installed above an electronic belt scale 3 in front of a drum-type blade rehumidifier 5; the electronic control device 8 is electrically connected to the visual recognition and laser engraving device 6, the visual recognition device 7 and a production line control device 13 respectively;

[0023] The visual recognition and laser engraving device 6 recognizes the range of the cigarette block 10 and carves a frame on the surface of the cigarette block 10, and numbers, characters or patterns are engraved in the frame; the frame on the cigarette block 10 serves as a dividing line of the cigarette block, and the numbers, characters or patterns in the frame serve as codes for the formula components of different origins, different grades and different water absorption; the electronic control device 8 transmits the recognized information to the production line control device 13; the system also includes a computer-readable storage medium described in the present invention.
