Description

Cigarette finished product box error correction device

Technical Field

The invention relates to the technical field of online sorting of finished cigarette boxes, and in particular to an error correction device for finished cigarette boxes.

Background technique

Finished cigarette box sorting is an essential part of the automatic logistics system for cigarette manufacturing. After the finished cigarette box is packaged, the national unified white "No. 1 engineering code" needs to be stamped on the lower right corner of the front of the cigarette box, which is called the "white code". It contains product information, proving that the product cigarettes are qualified and can be put into storage, and then stored in the finished product storage area. If the product is a re-inspected product, it is necessary to enter the re-inspected product storage area. On the side of the cigarette box, there is also a "product code" containing brand information. Finished cigarette boxes with different identification codes need to pass through the finished cigarette box sorting system to identify the engineering code category, and enter different storage areas after sorting.

At present, the domestic sorting system mainly scans the finished cigarette boxes with engineering codes for storage. During the storage process, the finished product brand information contained in the engineering code affixed to the front of the cigarette box is not compared with the brand information contained in the product code on the side of the cigarette box. There was a serial number accident in which the operator mistakenly added brand A to the brand B coding machine, resulting in brand A being mistakenly printed with brand B's "No. 1 engineering code" for storage. In production, re-inspected products without engineering codes are sometimes produced. Because the re-inspected products do not have engineering codes on the front of the cigarette box, but only product codes are printed on the side, they cannot be stored by scanning. Although some cigarette factories have realized the function of scanning the "factory identification code" (yellow code) for re-inspected products to enter the warehouse through technical transformation, there is still a hidden danger of serial number accidents due to the failure to compare the "factory identification code" with the product code information.

Therefore, in order to avoid the occurrence of serial number accidents, a cigarette finished product cigarette box error correction device is urgently needed.

Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

The current error correction device for finished cigarette boxes mainly consists of a scanning terminal, a mounting bracket, a PLC (Programmable Logic Controller) module, an electric cabinet, and a diversion solenoid valve. When the automatic logistics system delivers the finished cigarette box to the scanning station, the scanning terminal scans the finished cigarette box, identifies the brand information from the engineering code and transmits it to the PLC. The PLC identifies the barcode information to determine whether the cigarette box belongs to the "No. 1 engineering code" (white code) or the "factory identification code" (yellow code), and controls the diversion device to allow the finished cigarette boxes with different codes to enter the corresponding storage channel.

The current error correction device for finished cigarette boxes has the following problems: First, in the sorting of finished cigarette boxes, only the "No. 1 engineering code" and the "factory identification code" are distinguished, so that the cigarette boxes enter the finished product area and the re-inspection product area respectively, but the product code on the side of the finished cigarette box is not identified. If the product code on the finished cigarette box is different from the No. 1 engineering code on the cigarette box, it will cause serial numbers, but the current error correction device for finished cigarette boxes cannot identify it, so it cannot realize the error correction of serial number products. Secondly, in the production process, cigarettes are manually packed, and the packed cigarette boxes need to be put on the coding machine for coding. This means that the operator mistakenly adds the cigarette box of brand A to the coding machine of brand B, and brands brand A with the "No. 1 engineering code" of brand B, resulting in product serial numbers. The current error correction device for finished cigarette boxes does not have the function of comparing and identifying the product code and the "No. 1 engineering code", so there is no error correction for human error operation of serial numbers. If serial number products flow into the market, it will cause great harm to the brand image.

As shown in FIG1 , an embodiment of the present invention provides a cigarette finished product box error correction device, which includes a color mark sensor 12, an engineering code scanning terminal 1, an engineering code scanning terminal controller 2, a commodity code scanning terminal 4, a commodity code scanning terminal controller 3 and a programmable logic controller (PLC) 7, wherein, as shown in FIG2 , the output end of the color mark sensor 12 is connected to the input end of the programmable logic controller 7; the output end of the engineering code scanning terminal 1 is connected to the input end of the engineering code scanning terminal controller 2, and the output end of the engineering code scanning terminal controller 2 is connected to the input end of the programmable logic controller 7; the output end of the commodity code scanning terminal 4 is connected to the input end of the commodity code scanning terminal controller 3, and the output end of the commodity code scanning terminal controller 3 is connected to the input end of the programmable logic controller 7;

The color code sensor 12 is used to perform color code recognition on the engineering code on the front of the cigarette box 10, so as to distinguish the engineering code into a No. 1 engineering code and an in-factory identification code according to the recognized color; the engineering code scanning terminal 1 is used to recognize the No. 1 engineering code or the in-factory identification code on the front of the cigarette box 10; the engineering code scanning terminal controller 2 is used to convert the engineering code information recognized by the engineering code scanning terminal into a signal that can be recognized by the programmable logic controller 7; the commodity code scanning terminal 4 is used to recognize the commodity code on the side of the cigarette box 10; the commodity code scanning terminal controller 3 is used to convert the commodity code information recognized by the commodity code scanning terminal 4 into a signal that can be recognized by the programmable logic controller 7; The programmable logic controller 7 is used to write a control program, and the control program is used to compare the engineering code information recognized by the engineering code scanning terminal 1 with the commodity code information recognized by the commodity code scanning terminal 4 to determine whether the engineering code information is consistent with the commodity code information, and control the cigarette box 10 whose engineering code information is consistent with the commodity code information and corresponds to the No. 1 engineering code to enter the finished product warehouse, the cigarette box 10 whose engineering code information is consistent with the commodity code information and corresponds to the factory identification code to enter the re-inspection product warehouse, and the cigarette box 10 whose engineering code information is inconsistent with the commodity code information to enter the rejection channel.

The color mark sensor 12 can effectively identify the color of the engineering code on the front of the cigarette box 10, and convert it into an electrical signal that can be recognized by the programmable logic controller, effectively ensuring that the finished products and re-inspected products are stored in different channels. Specifically, there are two colors of the engineering code on the front of the cigarette box 10, namely white and yellow. If the color of the engineering code on the front of the cigarette box 10 identified by the color mark sensor 12 is white, it is determined that the engineering code corresponding to the cigarette box is the No. 1 engineering code. If the programmable logic controller 7 compares the engineering code information of the cigarette box with the commodity code information and the result is consistent (match), the cigarette box 10 finally enters the finished product warehouse; if the color of the engineering code on the front of the cigarette box 10 identified by the color mark sensor 12 is yellow, it is determined that the engineering code corresponding to the cigarette box is the factory identification code. If the programmable logic controller 7 compares the engineering code information of the cigarette box with the commodity code information and the result is consistent (match), the cigarette box 10 finally enters the re-inspected product warehouse.

The finished cigarette box error correction device also includes an alarm 5, which is connected to the programmable logic controller 7 and is used to output an alarm signal when the engineering code information is inconsistent with the commodity code information. Specifically, the alarm is installed on the top of the electric cabinet box at the cigarette box rejection port, and is used to remind the operator to manually recheck the commodity code and engineering code of the cigarette box when the cigarette box is rejected. As an example but not limitation, the alarm 5 can be an audible and visual alarm, which can remind manual recheck through the alarm signal to prevent serial number products from flowing into the next process. Exemplarily, the sound and light alarm indicates the status of the cigarette box through indicator lights of three different colors. In one implementation of the present invention, three indicator lights of green, red and yellow are used. If the color of the engineering code on the front of the cigarette box identified by the color mark sensor 12 is white, and the engineering code information of the cigarette box is consistent with the product code information, the sound and light alarm lights up green, and the cigarette box enters the finished product warehouse; if the color of the engineering code on the front of the cigarette box identified by the color mark sensor 12 is yellow, and the engineering code information of the cigarette box is consistent with the product code information, the sound and light alarm lights up yellow, and the cigarette box enters the re-inspection product warehouse; if the engineering code information of the cigarette box is inconsistent with the product code information, regardless of whether the color of the engineering code on the front of the cigarette box identified by the color mark sensor 12 is white or yellow, the sound and light alarm lights up red and flashes, and the cigarette box enters the rejection channel through the rejection port and is transported to the rejection point.

The programmable logic controller 7 can be a Siemens S7-300 programmable logic controller. The programmable logic controller 7 receives information transmitted by the engineering code scanning dock controller 2, the commodity code scanning dock controller 3 and the color code sensor 12, and controls the transportation and rejection of the cigarette box in real time through program writing. When the engineering code and the commodity code are inconsistent, the rejection solenoid valve is controlled to reject the cigarette box, and the alarm is controlled to sound an alarm to remind manual re-inspection.

The finished cigarette box error correction device also includes a human-machine interface 6, which is connected to the programmable logic controller 7, and is used to display alarm information and process faults according to the alarm information. At the same time, through the human-machine interface 6, the defect categories of the cigarette boxes entering the rejection channel can be viewed, and the defect categories specifically include incorrect cigarette boxes and incorrect engineering codes. Incorrect cigarette boxes refer to when the robot grabs the cigarette box or the human takes the cigarette box, the cigarette box of brand A is mistaken for the cigarette box of brand B. Incorrect engineering codes refer to when the packed cigarette box is placed on the coding machine for coding, the cigarette box of brand A is mistakenly added to the coding machine of brand B, which will cause brand A to be marked with the engineering code of brand B, resulting in product serial numbers.

Fig. 3 is a flow chart of the working state of the embodiment of the error correction device for finished cigarette boxes provided by the present invention. In operation, first, the color code sensor 12 performs color code recognition on the engineering code on the front of the cigarette box in place to determine the color of the engineering code. If it is white, the engineering code is the No. 1 engineering code; if it is yellow, the engineering code is the factory identification code. Next, if the color of the engineering code of the cigarette box is white, the engineering code scanning terminal 1 and the commodity code scanning terminal 4 are used to scan the No. 1 engineering code and commodity code respectively; then, the programmable logic controller 7 determines whether the two code information (No. 1 engineering code information and commodity code information) match through program control and calculation. If they match, the cigarette box enters the finished product warehouse; if they do not match, the cigarette box enters the rejection channel, the sound and light alarm gives a sound and light alarm, and then a manual re-inspection is performed. If the color of the engineering code of the cigarette box is yellow, the engineering code scanning terminal 1 and the commodity code scanning terminal 4 are used to scan the factory engineering code and commodity code respectively; then, the programmable logic controller 7 determines whether the two code information (factory engineering code information and commodity code information) are consistent through program control and calculation. If they are consistent, the cigarette box enters the re-inspection product warehouse; if they are not consistent, the cigarette box also enters the rejection channel, the sound and light alarm performs sound and light alarm, and then manual re-inspection is performed. Therefore, the cigarette finished product cigarette box error correction device of the present invention can solve the problem that the existing cigarette finished product cigarette box cannot compare and identify the re-inspection, the No. 1 engineering code and the commodity code, ensure that the products can be automatically sorted into different warehouses as needed, and increase the recognition of the commodity code, can identify and correct the cigarette box with the wrong engineering code, and remind manual re-inspection to avoid the serial number products from flowing into the next process.

Therefore, compared with the prior art, the finished cigarette box error correction device provided in this embodiment can effectively distinguish between the No. 1 engineering code and the factory identification code by identifying the engineering code through the color code sensor, and then can effectively distinguish between the finished products and the re-inspected products, and send the cigarette boxes with different engineering codes to the corresponding storage area, avoiding manual classification and reducing labor costs; by simultaneously scanning the engineering code on the front of the cigarette box and the product code on the side, and comparing the two codes, the cigarette boxes with inconsistent product information in the two code segments can be effectively identified and discarded, so that the cigarette boxes with inconsistent codes can be effectively corrected; and the cigarette boxes with erroneous engineering codes can be identified, avoiding the serial number of cigarette boxes, preventing unqualified products from flowing into the next process, and avoiding the waste of raw and auxiliary materials caused thereby; and the finished cigarette box error correction device operates stably, efficiently, reliably, and with high precision, has good detection performance, and is easy to adjust and maintain.

The finished cigarette box error correction device further comprises a rejection solenoid valve 8 connected to the programmable logic controller 7 and used for pushing the cigarette box 10 into the rejection channel when the engineering code information is inconsistent with the commodity code information.

The finished cigarette box error correction device also includes a mounting bracket 9, which is used to provide support for the color mark sensor 12, the engineering code scanning terminal 1, the engineering code scanning terminal controller 2, the commodity code scanning terminal 4, and the commodity code scanning terminal controller 3. Specifically, as shown in FIG1, the mounting bracket 9 includes a horizontal frame located at the top and vertical frames located at both sides to provide strong support for the color mark sensor 12, the engineering code scanning terminal 1, the engineering code scanning terminal controller 2, the commodity code scanning terminal 4, and the commodity code scanning terminal controller 3. Therefore, the finished cigarette box error correction device of the present invention can ensure the effectiveness of detection and the safety and orderliness of the cigarette box transportation channel.

Further, as shown in Figure 1, the engineering code scanning terminal controller 2 and the commodity code scanning terminal controller 3 are arranged on the side of the mounting bracket 9, and are respectively connected to the engineering code scanning terminal 1 and the commodity code scanning terminal 4, and can effectively process the engineering code information transmitted from the engineering code scanning terminal 1 and the commodity code information transmitted from the commodity code scanning terminal 4, convert the graphic signal into a digital signal, for example, a high level corresponds to 1, and a low level corresponds to 0, and transmit it to the programmable logic controller 7. The specific processing method can refer to the prior art, and the present invention will not repeat it.

The finished cigarette box error correction device also includes a box conveyor belt 11 for conveying the box 10. When the color of the engineering code on the front of the box 10 identified by the color mark sensor 12 is white, and the comparison result determined by the programmable logic controller 7 is consistent, the output signal of the programmable logic controller 7 controls the box conveyor belt 11 driven by the motor to push the box 10 into the finished product warehouse channel; when the color of the engineering code on the front of the box 10 identified by the color mark sensor 12 is yellow, and the comparison result determined by the programmable logic controller 7 is consistent, the output signal of the programmable logic controller 7 controls the box conveyor belt 11 driven by the motor to push the box 10 into the re-inspection product warehouse channel.
