Description

Detection system and detection method for lamina tobacco packets and tobacco making equipment

Technical Field

The disclosure relates to the field of tobacco automation control, in particular to a detection system and a detection method for a sheet tobacco package and a tobacco making device.

Background

At present, the preparation link of the tobacco throwing workshop production of domestic tobacco industry enterprises is that tobacco packets with different specifications required by recent production are transferred from each tobacco mellowing warehouse to a throwing area to be warehoused and stored in a tobacco lamina formula warehouse. The tobacco sheet packets are put on the tray to be put in storage. The trays are attached with tray bar codes to represent information of each tray. In order to manage the information of the cigarette packets with different specifications in the warehouse area, labels are attached to the cigarette packets to store the information of the cigarette packets. Fig. 1 is a schematic diagram showing a label on a packet of lamina cigarettes in the prior art. As shown in fig. 1, the tag 100 comprises: origin, code, date, name, net weight, bar code, etc.

Since the labels are attached when the cigarette packets are packed in a tobacco redrying factory and the cigarette packets are stored in a tobacco alcoholization warehouse for years, the label damage rate is high due to operations such as moving the warehouse, checking and killing insects, or part of the label bar codes are blocked due to improper binding positions of the binding bands, so that the label information is not easy to read by using a bar code reader in the traditional situation. The bar code information is manually input, or a marking machine is additionally arranged in a warehousing link, and the bar code reader can read and store the bar code information by manually marking and labeling again. Both the two modes waste time and labor, and cause lower working efficiency. Moreover, because the cards are manually input, the probability of errors exists, and the cards are easy to be mistaken.

Fig. 2 is a schematic diagram illustrating a detection system for cigarette packets in lamina form according to some embodiments of the present disclosure. As shown in fig. 2, the detection system includes: a trigger device 210, a label imaging detection device 220, a pallet bar code reader 230 and a warehouse management control device 240. The triggering device 210 is electrically connected with the label imaging detection device 220 and the tray barcode reader 230 respectively. The label imaging detection device 220 and the tray barcode reader 230 are electrically connected to the warehouse management control device 240 respectively. For example, the triggering device 210, the label imaging detection device 220, and the pallet barcode reader 230 may be installed on a cigarette warehousing passage of a tobacco lamina formula library.

The triggering device 210 is configured to send a first triggering signal to the label imaging detection device 220 and send a second triggering signal to the pallet barcode reader 230 after detecting the pallet carrying the sheet cigarette packets. For example, the triggering device may comprise a capacitive proximity sensor. When the tray approaches the capacitive proximity sensor, the magnetic force changes, triggering a signal. Of course, it will be appreciated by those skilled in the art that the triggering means may take the form of other sensors, such as photoelectric sensors, etc.

The label imaging detection device 220 is configured to perform imaging detection on a label of the sheet tobacco bale after receiving the first trigger signal, identify label information of the sheet tobacco bale if the label detection is successful, and send the label information to the warehousing management control device 240. For example, as shown in fig. 1, the tag information may include: at least one of the numerical information converted from the cigarette packet bar code image 101, the cigarette packet bar code numerical information 102, and the cigarette packet code information 103. For example, the cigarette packet barcode image information may correspond to binary digital information, i.e., each digit of the cigarette packet barcode may correspond to "0" or "1". After the label imaging detection device identifies the binary digital information corresponding to the cigarette packet bar code image, the binary digital information can be converted into decimal digital information, and then the decimal digital information is sent to the warehousing management control device.

The cigarette packet barcode digital information 102 is digital information below the cigarette packet barcode image. The cigarette packet bar code digital information 102 can be directly obtained from a cigarette packet label. For example, the cigarette packet barcode digital information 102 is equal to the digital information converted from the cigarette packet barcode image 101.

The tray barcode reader 230 is configured to detect barcode information of the tray after receiving the second trigger signal, read the barcode information of the tray when the tray barcode detection is successful, and send the barcode information to the warehousing management control device 240.

The warehousing management control device 240 is configured to obtain cigarette packet information of the sheet cigarette packet according to the tag information, bind and mark the cigarette packet information and the barcode information of the tray, and store the bound cigarette packet information and the barcode information of the tray.

In some embodiments, the warehouse management control device may be implemented in the form of a controller, and implemented in the form of a control circuit. For example, the control circuit may include a comparison circuit, an amplification circuit, a memory, and the like.

In some embodiments, the warehousing management control device is configured to compare the label information with the delivery note to obtain the cigarette packet information of the corresponding sheet cigarette packet. For example, the warehousing management control device may receive a delivery order sent by the upper system. The delivery note comprises cigarette packet information of all the lamina cigarette packets to be put in storage at this time. For example, the delivery slip may be calculated on a daily basis, i.e. including the information on the packets of all lamina tobacco packets that arrive at the delivery throughout the day. For example, the cigarette packet information may include: production place, code information, production date, product name, net weight, cigarette packet bar code digital information and the like.

To this end, a detection system for packets of lamina tobacco cigarettes according to some embodiments of the present disclosure is provided. In the detection system, after a trigger device detects a tray carrying a sheet tobacco packet, a label imaging detection device and a tray bar code reader are respectively triggered to detect; the label imaging detection device carries out imaging detection on the label of the sheet tobacco package and sends the label information to the warehousing management control device; the tray bar code reader detects bar code information of the tray and sends the bar code information of the tray to the storage management control device; the warehousing management control device obtains cigarette packet information of the sheet cigarette packets according to the label information, binds and marks the cigarette packet information and the bar code information of the tray, and stores the bound cigarette packet information and the bar code information of the tray. Like this, through the automated inspection to slice tobacco bale label and tray bar code, can be so that the system of typeeing that the relevant information of slice tobacco bale can be accurate rapidly, improve work efficiency. In addition, the condition of wrong cards can be reduced. Moreover, the cigarette packet information and the bar code information of the tray are bound, so that the cigarette packet position can be conveniently positioned in the subsequent process.

Fig. 3 is a schematic diagram illustrating a detection system for cigarette packets in sheet form according to further embodiments of the present disclosure. As shown in fig. 3, the detection system may include: a trigger device 210, a label imaging detection device 220, a pallet bar code reader 230 and a warehouse management control device 240.

In some embodiments, as shown in fig. 3, the detection system may further include a cigarette packet transport actuator 350. The cigarette packet conveying executing mechanism 350 is electrically connected with the warehouse management control device 240. The cigarette packet conveying executing mechanism 350 is configured to convey the lamina cigarette packets to a lamina formula library shelf after receiving the first transportation instruction. The warehouse management control device 240 may be further configured to send the first transportation instruction to the cigarette packet conveying actuator 350 (e.g., to a controller of the cigarette packet conveying actuator 350) after the cigarette packet information and the barcode information of the tray are bound and marked.

In the above embodiment, the warehousing management control device sends the first transportation instruction to the cigarette packet conveying execution mechanism after binding and marking the cigarette packet information and the barcode information of the tray, so that the cigarette packet conveying execution mechanism conveys the lamina tobacco packets to the lamina tobacco formula warehouse shelf. Thus, the operation of warehousing the lamina tobacco packets is realized.

In some embodiments, as shown in fig. 3, the detection system may further include a first alarm unit 360. The first alarm unit 360 is electrically connected to the warehouse management control device 240. The first alarm unit 360 is used for alarming (e.g. sound alarm or indicator light alarm) after receiving the first alarm signal. The label imaging detection device 220 may also be configured to send information that the label detection is unsuccessful to the warehouse management control device 240 if the label information of the lamina tobacco bale cannot be identified. The warehouse management control device 240 may be further configured to send a second transportation instruction to the cigarette packet conveying executing mechanism 350, send a first alarm signal to the first alarm unit 360, and receive manually input cigarette packet information after receiving the information that the tag detection is unsuccessful. The cigarette packet conveying executing mechanism 350 may be further configured to convey the lamina cigarette packets to an abnormal cigarette packet processing station (not shown in fig. 3) after receiving the second transportation instruction.

In the above embodiment, the label imaging detection device sends information that the label detection is unsuccessful to the warehouse management control device in a case where the label information of the lamina tobacco bale cannot be identified. And after receiving the information that the label detection is unsuccessful, the warehousing management control device sends a second transportation instruction to the cigarette packet conveying execution mechanism, so that the cigarette packet conveying execution mechanism conveys the sheet cigarette packets to the abnormal cigarette packet processing platform. The warehouse management control device also sends a first alarm signal to the first alarm unit, so that the first alarm unit gives an alarm to remind workers. The staff can carry out manual identification to the tobacco bale label information that the system can not discern at unusual tobacco bale processing station platform, inputs the tobacco bale information to storage management controlling means through the mode of manual entry. Therefore, processing of cigarette packet label information which cannot be identified by the system is realized, the label information of the cigarette packet is identified, and then warehousing operation is carried out on the cigarette packet.

In some embodiments, as shown in fig. 3, the detection system may further include a second alarm unit 370. The second alarm unit 370 is electrically connected to the stocker management control device 240. The second alarm unit 370 is used for alarming (e.g. sound alarm or indicator light alarm) after receiving the second alarm signal. The tray barcode reader 230 may also be configured to send a message that the detection of the tray barcode is unsuccessful to the warehouse management control device 240 in case that the barcode information of the tray cannot be read out. The warehouse management control device 240 may be further configured to send a second transportation instruction to the cigarette packet conveying executing mechanism 350 and send a second alarm signal to the second alarm unit 370 after receiving the information that the barcode detection of the tray is unsuccessful, and to receive the manually input barcode information of the tray. The cigarette packet conveying executing mechanism 350 may be further configured to convey the sheet cigarette packets to the abnormal cigarette packet processing station after receiving the second transportation instruction.

In the above embodiment, when the barcode information of the tray cannot be read out, the tray barcode reader sends information that the detection of the tray barcode is unsuccessful to the warehouse management control device. And after receiving the information that the tray bar code detection is unsuccessful, the warehousing management control device sends a second transportation instruction to the cigarette packet conveying executing mechanism, so that the cigarette packet conveying executing mechanism conveys the sheet cigarette packets to the abnormal cigarette packet processing platform. The warehouse management control device also sends a second alarm signal to the second alarm unit, so that the second alarm unit gives an alarm to remind workers. Staff can carry out manual identification to the tray bar code information that the system can not discern at unusual tobacco bale processing station platform, inputs the bar code information of tray to storage management controlling means through the mode of artifical input. Therefore, the processing of the bar code information of the tray which can not be identified by the system is realized, the bar code information of the tray is identified, and then the cigarette packet is put into storage by using the tray.

The detection system of the above-described embodiment of the present disclosure can implement coexistence of two modes, an automatic mode and a manual mode. The detection system can realize that most of the sheet tobacco package labels are detected and stored in an automatic mode, and manual mode recording is carried out when a small amount of the sheet tobacco package labels cannot be detected.

Fig. 4 is a schematic diagram illustrating a structure of a label imaging detection apparatus according to some embodiments of the present disclosure. Fig. 5 is a schematic diagram illustrating segmentation of a label image into multiple regions according to some embodiments of the present disclosure. Label imaging detection devices according to some embodiments of the present disclosure are described in detail below in conjunction with fig. 4 and 5.

In some embodiments, as shown in fig. 4, the label imaging detection apparatus may include: an optical imaging unit 221, an image acquisition unit 222, and an image processing unit 223. The optical imaging unit 221 is electrically connected to the image pickup unit 222. The image acquisition unit 222 is electrically connected to the image processing unit 223. For example, the image acquisition unit 222 may include an image acquisition card.

The optical imaging unit 221 is configured to image a label of the sheet cigarette packet to obtain a label image.

The image capturing unit 222 is configured to capture a label image and transmit the label image to the image processing unit 223.

The image processing unit 223 is configured to divide the label image into a plurality of regions, detect the plurality of regions respectively, determine that the label detection is successful when information in at least one of the plurality of regions is detected, send the information in the at least one region to the warehousing management control device 240 as label information of a tobacco lamina packet, and send information that the label detection is unsuccessful to the warehousing management control device when none of the information in the plurality of regions is detected.

For example, the image processing unit may employ a threshold-based image segmentation method. Of course, it will be understood by those skilled in the art that the image processing unit may also employ other image segmentation methods, such as a region-based image segmentation method, an edge-based image segmentation method, or an image segmentation method based on a particular theory, etc.

In some embodiments, as shown in fig. 5, the plurality of regions may include: a first region 510, a second region 520, and a third region 530. The first region 510 may include cigarette packet barcode image information 101. This second region 520 may include cigarette packet barcode digital information 102. The third field 530 may include cigarette packet code information 103.

It should be noted that the above-described "detecting information in at least one of the plurality of areas" indicates that the complete information in the at least one area is detected. For example, the detection of the first region information refers to the detection of complete information of the cigarette packet bar code image in the first region, and does not refer to the detection of only partial information of the cigarette packet bar code image. Other regions are similar.

To this end, a label imaging detection apparatus according to some embodiments of the present disclosure is provided. In the label imaging detection device, an optical imaging unit and an image acquisition unit are used for obtaining an integral image of a label of a cigarette packet; then, the image processing unit divides the whole cigarette packet label image into a plurality of areas and performs subarea detection. Therefore, through the partition detection, the detection speed and the detection precision can be improved, and the fault tolerance rate can be reduced.

For example, the following information of 3 areas can be detected: cigarette packet bar code image information, cigarette packet bar code digital information and cigarette packet code information. For the information of the 3 areas, at least one acquisition is successful, and the label information is acquired successfully.

In some embodiments, one code may correspond to one or more cigarette packets, one cigarette packet corresponding to a unique cigarette packet barcode. Since a plurality of cigarette packets with the same code are different in shift generally, the cigarette making formula is not influenced, and therefore, the code information can be used as the label information for detection.

In some embodiments, the image processing unit 223 is configured to determine that the tag detection is successful if at least one of the following three conditions is satisfied, and otherwise determine that the tag detection is unsuccessful. The three conditions include: the number of bar code digits of the cigarette packet bar code image information is equal to the number of preset cigarette packet bar codes; the number digit of the cigarette packet bar code digital information is equal to the preset number digit of the cigarette packet bar code; and the code bit number of the cigarette packet code information is equal to the preset cigarette packet code bit number.

In the above embodiment, the number of bits of the information in each region is compared with the respective predetermined correct number of bits. If the number of bits is equal, it indicates that the corresponding information is successfully acquired.

For example, for a certain cigarette packet label, the preset lowermost bar code is 50 digits, if the label imaging detection device recognizes 50 digits at the position of the bar code, the reading is determined to be successful, and if only 49 digits are recognized, the reading of the bar code is determined to be failed. Similarly, the number below the bar code is also predetermined to be 50 bits and the code is predetermined to be 6 bits. As long as the corresponding number of bits is correct at the time of reading, it is determined that the reading is successful. It should be noted that the embodiments of the present disclosure ignore the situation of reading a digit in a bit by mistake.

In some embodiments, the image processing unit 223 may be configured to cut the characters in each region to obtain each character in each region, and compare each character with preset word stock data, so as to identify character information in each region. This realizes a recognition function for the characters in each region.
