Description
Technical Field
The present disclosure relates to the field of control, and more particularly, to a transmission control system.
Background
At present, the two-dimension code technology is widely applied to the tobacco industry, especially in the production, storage and delivery links of finished cigarette pieces. For example, each finished cigarette must have a unique 32-bit one-dimensional code (referred to as "one-dimensional engineering code" in the industry) for tracking the information of cigarette commodities by taking the finished cigarette as a unit, thereby realizing code fetching, warehousing and delivery logistics tracking of a finished cigarette production plan, realizing industrial and commercial data integration of the tobacco industry and timely, accurate and comprehensive monitoring and management of cigarette production, and further improving scientific management of industrial production and operation decisions.
The conventional process of applying the engineering code I in the cigarette industry is as follows:
1. before the cigarette factory workshop is produced, the national tobacco monopoly bureau is required to repeat and issue a number of engineering code sections, and the workshop can produce the cigarette.
2. In the cigarette production link of the cigarette rolling workshop, the labeling machine acquires the copied first engineering code through the computer system, pastes the paper first engineering code label at the fixed position of the cigarette box, and then enters the warehousing and logistics conveying link.
3. After the cigarette pieces are conveyed to a sorting line of a logistics system, the sorting line utilizes a bar code recognizer to recognize a first engineering code, and cigarettes of different brands are automatically sorted. Of course, manual sorting may also be performed.
4. After the cigarette pieces enter different brand channels through sorting, the cigarette pieces are stacked on the tray by a robot (or manually stacked), and the engineering code information of each cigarette piece on the tray is bound with the tray. And then entering a warehouse for storage.
5. When a delivery order is available, the logistics scheduling computer system finds the corresponding tray according to the number and quantity of the order, generates a tray placing task, and the system automatically delivers and places the tray.
6. After the cigarettes are put off the shelf, unstacking the cigarettes in each stack through a robot or manually to a logistics telescopic conveyor, wherein a bar code identification system is arranged on the telescopic conveyor and used for identifying the bar codes on the cigarettes passing through and reporting the bar codes to an engineering code management system through serial port connection. Finally, the carrier carries the scanned cigarette pieces to a carriage butted with the scanned cigarette pieces from the telescopic conveyor.
SUMMERY OF THE UTILITY MODEL
The inventor notices that the following defects exist in the link of unloading and code scanning of cigarette cartons:
1. the scanned bar code is directly sent to the management system by the scanner arranged on the telescopic conveyor, and the management system can prompt an alarm when acquiring repeated codes or wrong codes. However, since there is no interaction between the management system and the telescopic conveyor, the telescopic conveyor does not stop, in which case manual intervention is required in order to hold the cigarettes in duplicate or wrong codes. If the alarm is not timely, the handler needs to carry the cigarettes stacked on the carriage again and then scan the cigarettes by the telescopic conveyor again, so that the cigarettes with the overlapped codes or the wrong codes can be found out.
2. In some cases, the scanner successfully scans the bar code, but due to communication failure, the management system does not receive the bar code information, so that the delivery quantity recorded by the system is inconsistent with the delivery quantity of the warehouse management system. If the data difference is not found in time and the telescopic machine is not stopped, the cigarette carton is directly conveyed to the carriage. When the single delivery is finished, if the number of the cigarettes is not consistent, the carrying workers need to re-count the cigarettes already loaded in the carriage.
In a word, in the ex-warehouse scanning process, the first engineering code management system and the telescopic machine do not interact, so that repeated carrying can often occur due to the fact that the first engineering code management system and the telescopic machine are not easy to find in time when repeated codes, wrong codes and unreceived codes occur, and certain influence is caused on accuracy and timeliness of manpower, material resources and finished product delivery.
Therefore, the technical scheme capable of timely finding out the bar code abnormality and controlling the conveyor to stop is provided.

Fig. 1 is a schematic structural diagram of a transmission control system according to an embodiment of the present disclosure. As shown in fig. 1, the transfer control system includes a photodetector 11, a conveyor controller 12, a scanner 13, a management controller 14, and a conveyor 15.
The photodetector 11 is used to detect whether a cigarette piece is present on the conveyor 15.
For example, if the piece of cigarette blocks the light emitted by the photodetector during the conveying process of the piece of cigarette on the conveyor, the photodetector determines that the piece of cigarette arrives, and if the piece of cigarette does not block the light emitted by the photodetector any more, the piece of cigarette is indicated to have passed through the photodetector.
The conveyor controller 12 is configured to set the indication information to a first value when the photodetector 11 switches from a state in which a cigarette is not detected to a state in which a cigarette is detected.
For example, when the photodetector 11 is switched from a state in which a cigarette is not detected to a state in which a cigarette is detected, the conveyor controller 12 sets the db0.dbw0 data to 0.
In some embodiments, the conveyor controller 12 initiates the start of the conveyor operation at the direction of the user.
The scanner 13 is configured to scan barcode information on a cigarette piece when the photodetector 11 can detect the cigarette piece, and send the obtained barcode information to the management controller 14.
In some embodiments, the barcode information includes a one-dimensional barcode, a two-dimensional code, or other types of barcode information.
The management controller 14 is configured to verify the received barcode information, and if the verification fails, the indication information in the conveyor controller 12 is not updated.
When the photodetector 11 is switched from a state in which a cigarette is detectable to a state in which no cigarette is detectable, the conveyor controller 12 controls the conveyor to stop operating if the current value of the instruction information is still the first value.
Here, under the trigger that the photodetector 11 can detect a cigarette, the scanner 13 scans the barcode information on the cigarette and sends the obtained barcode information to the management controller 14. In order to enable the scanner 13 to successfully scan the barcode information, the scanner 13 may continue to scan the barcode until the barcode information is successfully scanned if the photodetector 11 can detect a cigarette. The management controller 14 verifies the received barcode information. If the management controller 14 does not receive the barcode information, or the received barcode information is repeated and is an error code, it is determined that the verification fails. In this case, the indication information in the conveyor controller 12 is not updated. I.e., db0.dbw0 data is still 0.
When the photodetector 11 is switched from a state in which a cigarette is detectable to a state in which no cigarette is detectable, the conveyor controller 12 controls the conveyor to stop operating if the current value of the instruction information is still the first value.
Here, when the photodetector 11 is switched from a state in which a cigarette can be detected to a state in which a cigarette cannot be detected, the scanner does not scan the barcode any more. If the current value of the indicator information is still the first value (for example, db0.dbw0 data is still 0), the conveyor is controlled to stop working, so that the staff can perform corresponding manual processing to prevent the problematic cigarette pieces from performing the next process.
In some embodiments, the management controller 14 is further configured to update the indication information in the conveyor controller 12 to a second value if the verification is successful. For example, DB0.DBW0 data is modified to 1.
When the photodetector 11 is switched from a state in which a cigarette can be detected to a state in which no cigarette can be detected, the conveyor controller 12 controls the conveyor to continue operating if the current value of the instruction information is the second value.
For example, if the photodetector 11 is switched from a state in which a cigarette is detected to a state in which no cigarette is detected, and the db0.dbw0 data is changed from 0 to 1, it indicates that the barcode of the cigarette currently passing through the photodetector 11 is successfully verified. In which case the conveyor controller 12 will maintain the conveyor in operation.
In some embodiments, scanner 13 is communicatively coupled to management controller 14 via a serial port line. The management controller 14 is communicatively coupled to the conveyor controller 12 via ethernet.
In the transmission control system provided by the above embodiment of the present disclosure, the conveyor controller 12 and the management controller 14 are in communication connection, so that the conveyor controller 12 can timely control the conveyor to stop working under the condition that the barcode information is abnormal according to the barcode verification result of the management controller 14, thereby effectively preventing the problematic cigarette carton from entering the next processing link.
In some embodiments, the conveyor controller 12 counts the time when the current value of the indicator is the second value, and controls the conveyor to stop if the current value of the indicator remains at the second value for a predetermined time period.
For example, the conveyor controller 12 counts the time when the db0.dbw0 data is 1. If the photodetector 11 detects a cigarette again, the conveyor controller 12 resets the db0.dbw0 data to 0, and continues processing according to the scheme described in the above embodiment. If the db0.dbw0 data is kept at 1 in the predetermined time range, it indicates that no cigarette is detected by the photodetector 11 in the time range, which indicates that the cigarette processing of the current batch is completed. In this case, the conveyor controller 12 controls the conveyor to stop operating.
Fig. 2 is a schematic structural diagram of a transmission control system according to another embodiment of the present disclosure.
As shown in fig. 2, in the transmission control system, the photodetector 11 includes a transmitting section 111 and a receiving section 112. The transmitting portion 111 is located on one side of the conveyor 15, and the receiving portion 112 is located on the other side of the conveyor 15. The transmitter 111 transmits an optical signal, and the receiver 112 receives an optical signal. When there is no cigarette on the conveyor 15, the optical signal transmitted by the transmitting unit 111 is received by the receiving unit 112. When a cigarette pallet is present on the conveyor 15, if the cigarette pallet moves between the transmitting unit 111 and the receiving unit 112, the receiving unit 112 is blocked, and the receiving unit 112 switches from a state in which it can receive an optical signal to a state in which it cannot receive the optical signal. In this case, it is determined that the state in which the cigarette is never detected is currently switched to the state in which the cigarette is detected.
Furthermore, if the cigarette pieces on the conveyor 15 continue to move forward, the receiving portion 112 is no longer shielded. In this case, the receiving unit 112 can receive the optical signal transmitted by the transmitting unit 111. In this case, the receiving unit 112 switches from a state in which the optical signal cannot be received to a state in which the optical signal can be received, thereby determining that the current state is switched from a state in which the cigarette is detectable to a state in which the cigarette is not detectable.
Through implementing the above-mentioned embodiment of this disclosure, under the condition that the bar code on the cigarette piece is repeated, has the error, the management controller can be through carrying out the verification to the bar code information of scanner conveying, and conveyer controller can in time control conveyer stop work under the condition of verification failure to the cigarette piece that has the problem gets into next processing link.
In addition, when communication between the scanner and the management controller is failed, the management controller cannot receive barcode information transmitted by the scanner. In this case, the conveyor controller can also control the conveyor to stop working in time, so that staff can maintain the conveyor in time, and the condition that the counted delivery quantity is inconsistent with the actual delivery quantity is avoided.
In some embodiments, the functional unit modules described above may be implemented as a general purpose Processor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable Logic device, discrete gate or transistor Logic, discrete hardware components, or any suitable combination thereof for performing the functions described in this disclosure.
The description of the present disclosure has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the disclosure in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the disclosure and the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various embodiments with various modifications as are suited to the particular use contemplated.
