Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a method for associating cigarette carton and strip two-dimensional code information with multi-point verification function. Background Art

[0002] The auxiliary machine of the tobacco packaging machine is responsible for processes such as adding small transparencies to small boxes, packing small boxes into strips, and adding strip transparencies to strip boxes. The equipment has a high degree of automation and good integration. At present, the State Tobacco Monopoly Administration is organizing technical forces to track tobacco products by adding two-dimensional codes to tobacco product packaging. Therefore, it is necessary to transform the existing tobacco packaging machines to achieve the reading of two-dimensional codes on the production line. Due to the limitations of the existing equipment and working conditions on the production line, in addition to installing barcode readers, a series of data recovery and verification are also required to improve the data reading rate and ensure accuracy.

[0003] In the actual existing test solutions, the data repair function is not used. Due to the influence of the recognition rate, a large number of goods are rejected, resulting in a decrease in the actual finished product rate. Chinese Patent Document CN2021106475822 discloses a method and device for associating cigarette carton and strip two-dimensional code information with verification function, which is different in the verification position, the data recovery method, and the method of pulling small box data corresponding to strip cigarettes.

[0004] The present invention provides a method for associating cigarette carton and strip two-dimensional code information with multi-point verification function, which reduces the rejection of strips caused by the failure of associating strip information due to the existence of unreadable records in the carton code queue and the failure of reading at the carton code verification station, increases the finished product rate, and uses phase insertion delimiters without the need to reduce the decoding time. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for associating cigarette carton and strip two-dimensional code information with multi-point verification function, which reduces the rejection of strips caused by the failure of associating strip information due to the existence of unreadable records in the carton code queue and the failure of reading at the carton code verification station, and increases the finished product rate.

[0006] To achieve the above technical purpose and reach the above technical effect, the present invention discloses a method for associating cigarette carton and strip two-dimensional code information with multi-point verification function.

[0007] First, before the carton code reading station, there will be a carton code inspection station. The carton code inspection station is usually located before the small carton is wrapped in the small transparent film. It is used to verify the quality of the two-dimensional code and reject it when the reading fails. The small cartons after being read by the carton code inspection station may be rejected due to unreadable two-dimensional codes or other reasons (failed appearance inspection, hot start). For the vacancies generated by the rejection, the equipment body will fill them through a supplementary packer before the carton code reading station. The barcodes read by the carton code inspection station (Item information: where State.Decoded is set, BarCode stores the recognized barcode, the same below, or the position where the recognition fails: Item information, where State.Decoded is not set, the same below) are put into the "pre-reading queue". For those rejected due to non-software reasons (such as failed equipment appearance detection, hot start, etc.) after being scanned by the carton code inspection station, the ToBeEjected corresponding to the small carton data should be set. If the carton code reading station is designed to read one barcode each time: the read barcode (or the position where the recognition fails) is put into the "main reading queue"; if the carton code reading station is designed to read two barcodes in a stacked package each time, there will be three possibilities. 1. If two barcodes can be successfully read or it can be confirmed which small cartons the unread barcodes belong to: in the order consistent with the pre-reading queue according to the stacking order, the two barcode information (or the positions where the recognition fails) are put into the "main reading sequence". 2. If one barcode can be read: an ItemWithMissingPair information (where State.Decoded is set and BarCode stores the recognized barcode) is put into the "main reading sequence". 3. If no barcode can be read: an ItemWithMissingPair information (where State.Decoded is not set) is put into the "main reading sequence"; or two Item information (where State.Decoded is not set) are put into the "main reading sequence".

[0008] Secondly, when the carton code reading station of the packaging machine can determine that the current scanning position is the first pack (or the first two packs) of a strip based on the phase, before triggering the scanning, a Splitter object is inserted into the "main reading queue". This object will be used to split the small carton data. This splitting method is called the delimiter method below. When associating the carton and strip data, the delimiter method and the split code method are two mutually exclusive methods;

[0009] When using the delimiter method,

[0010] S1. At an appropriate trigger position (such as the generation moment of the 25 - flat package, the trigger moment at the barcode reading station, etc.), extract the data in the box code queue, form a box code package, and place it in the "box code package queue". The rule for forming a data package is to continuously extract multiple box codes from the "box code queue" until a Splitter object is extracted. The Validated property of the package uses late binding (calculating the value of the expression each time it is obtained), and its expression is:

[0011] a. When the number of small box barcode elements in the package is 10 and the Validated of each element is true, set it to True;

[0012] b. In other cases, set it to False;<s

[0013] c. This method does not set the Pending state;

[0014] S2. When data is added to the "barcode reading queue", extract the data as the barcode to be bound, extract a package (containing multiple box codes) from the "box code package queue", and bind the barcode and the box code as box - barcode associated data. Its state uses late binding (calculating the value of the expression each time it is obtained), and its expression is:

[0015] a. When the barcode's Validated is true and the box code package's Validated is True, set it to True;

[0016] b. In other cases, set it to False;

[0017] c. This method does not set the Pending state;

[0018] S3. Due to the difference in the number of workstations between the packing trigger moment and the barcode reading station, it is necessary to manually count the number of small boxes (accurate to the number of strips) between the two, and insert a Splitter object at the head of the "box code queue" according to the number of strips (rounded up) for workstation alignment;

[0019] When using the separator code method,

[0020] W1. It is necessary to add a box code verification workstation. According to the model limitations, it can usually be installed at a position suitable for reading the barcode of the first stack (the 1st / 2nd package) of the 25 - flat package or at a position suitable for reading the barcode of the fifth stack (the 9th / 10th package) of the 25 - flat package;

[0021] W2. The box code verification workstation reads two barcodes of one stack (two boxes) at a time, and the value returned each time is packed and placed in the "box code verification queue". The acceptable return values are:

[0022] a. When two barcodes are successfully read: Return two barcode elements (BarCodeWithLocation objects) with Location attribute values (location numbers, such as 1 / 2 / 9 / 10).

[0023] b. When one barcode is successfully read: Return one barcode element (BarCodeWithLocation object) without a Location attribute value.

[0024] c. When no barcode is read: Return an empty array.

[0025] W3. At appropriate trigger positions (such as the generation moment of the 25-piece flat package, the trigger moment of the barcode reading station, the trigger moment of the box code verification station, etc.), extract the data in the box code queue, form a box code package, and place it in the "box code package queue".

[0026] W4. After data is added to the "barcode reading queue", extract its data as the barcode to be bound, extract one package (containing multiple box codes) from the "box code package queue", and bind the barcode and the box code as box-barcode associated data. Its status adopts late binding (calculate the value of the expression each time it is obtained), and its expression is:

[0027] a. When the barcode Validated is true and the Validated of the box code package is True, set it to True.

[0028] b. When the barcode Validated is true and the Validated of the box code package is Pending, set it to Pending.

[0029] c. In other cases, set it to False.

[0030] W5. At the packing trigger moment, there is a difference in the number of workstations between the barcode reading station. It is necessary to manually count the number of small boxes between the two (accurate to the number of strips), and insert an empty package object at the head of the "box code package queue" according to the number of strips (rounded up) for workstation alignment.

[0031] The present invention has the following beneficial effects: At reasonable verification positions and with better data repair, it greatly reduces the rejection of strips caused by the failure of reading records in the box code queue and the failure of reading at the box code verification station, increasing the yield. Using phase insertion delimiters does not require reducing the decoding time. Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments.

[0033] The present invention discloses a method for associating cigarette carton and strip two-dimensional code information with a multi-point verification function, characterized in that:

[0034] First, before the carton code reading station, there is also a carton code inspection station, which is usually located before the small box is inserted into the small transparent film, used to verify the quality of the two-dimensional code and reject it when the reading fails. The small box after being read by the carton code inspection station may be rejected due to unreadable two-dimensional code or other reasons (failed appearance inspection, hot start). For the vacancies generated by the rejection, the equipment body will make up for them through a replenishing device before the carton code reading station. The barcodes read by the carton code inspection station (Item information: where State.Decoded is set, BarCode stores the recognized barcode, the same below, or the position where recognition fails: Item information, where State.Decoded is not set, the same below) are put into the "pre-reading queue". If the small box is rejected due to non-software reasons (such as failed equipment appearance inspection, hot start, etc.) after being scanned by the carton code inspection station, the ToBeEjected corresponding to the small box data should be set. If the carton code reading station is designed to read one barcode each time: the read barcode (or the position where recognition fails) is put into the "main reading queue"; if the carton code reading station is designed to read two stacked barcodes each time, there are three possibilities: 1. If two barcodes can be successfully read or the small box to which the unread barcode belongs can be confirmed: in the order consistent with the pre-reading queue according to the stacking order, the two barcode information (or the position where recognition fails) are put into the "main reading sequence"; 2. If one barcode can be read: an ItemWithMissingPair information (where State.Decoded is set and BarCode stores the recognized barcode) is put into the "main reading sequence"; 3. If no barcode can be read: an ItemWithMissingPair information (where State.Decoded is not set) is put into the "main reading sequence"; or two Item information (where State.Decoded is not set) are put into the "main reading sequence";

[0035] Secondly, when the carton code reading station of the packaging machine can judge that the current scanning position is the first pack (or the first two packs) of a strip according to the phase, before triggering the scanning, a Splitter object is inserted into the "main reading queue", and this object will be used to split the small box data. This splitting method is hereinafter referred to as the delimiter method. When associating the carton and strip data, the delimiter method and the split code method are two mutually exclusive methods;

[0036] When using the delimiter method,

[0037] S1. At an appropriate trigger position (such as the generation moment of the 25-ping package, the trigger moment of the barcode reading station, etc.), extract the data in the box code queue, form a box code package, and place it in the "box code package queue". The rule for forming the data package is to continuously extract multiple box codes from the "box code queue" until a Splitter object is extracted. The Validated attribute of the package uses late binding (calculating the value of the expression each time it is obtained), and its expression is:

[0038] a. When the number of small box barcode elements in the package is 10 and the Validated of each element is true, set it to True;

[0039] b. In other cases, set it to False;

[0040] c. This method does not set the Pending state;

[0041] S2. When data is added to the "barcode reading queue", extract the data as the barcode to be bound, extract a package (containing multiple box codes) from the "box code package queue", and bind the barcode and the box code as box-barcode associated data. Its state uses late binding (calculating the value of the expression each time it is obtained), and its expression is:

[0042] a. When the barcode Validated is true and the Validated of the box code package is True, set it to True;

[0043] b. In other cases, set it to False;

[0044] c. This method does not set the Pending state;

[0045] S3. Due to the difference in the number of workstations between the packing trigger moment and the barcode reading station, it is necessary to manually count the number of small boxes between the two (accurate to the number of strips), and insert a Splitter object at the head of the "box code queue" according to the number of strips (rounded up) for workstation alignment;

[0046] When using the separator code method,

[0047] W1. It is necessary to add a box code verification workstation. According to the model limitations, it can usually be installed at a position suitable for reading the barcode of the first stack (the 1st / 2nd package) of the 25-ping package or at a position suitable for reading the barcode of the fifth stack (the 9th / 10th package) of the 25-ping package;

[0048] W2. The box code verification workstation reads two barcodes of one stack (two boxes) at a time, and the value returned each time is packed and placed in the "box code verification queue". The acceptable return values are:

[0049] a. When two barcodes are successfully read: Return two barcode elements (BarCodeWithLocation objects) with Location attribute values (location numbers, e.g., 1 / 2 / 9 / 10).

[0050] b. When one barcode is successfully read: Return one barcode element (BarCodeWithLocation object) without a Location attribute value.

[0051] c. When no barcode is read: Return an empty array.

[0052] W3. At an appropriate trigger position (e.g., the generation moment of the 25-piece flat package, the trigger moment of the barcode reading station, the trigger moment of the box barcode verification station, etc.), extract the data in the box barcode queue, form a box barcode package, and place it in the "box barcode package queue".

[0053] W4. After data is added to the "barcode reading queue", extract its data as the barcode to be bound, extract a package from the "box barcode package queue" (containing multiple box barcodes), and bind the barcode and the box barcode as box-barcode association data. Its status uses late binding (calculate the value of the expression each time it is obtained), and its expression is as follows:

[0054] a. When the barcode Validated is true and the Validated of the box barcode package is True, set it to True.

[0055] b. When the barcode Validated is true and the Validated of the box barcode package is Pending, set it to Pending.

[0056] c. In other cases, set it to False.

[0057] W5. At the packing trigger moment, there is a difference in the number of workstations between the barcode reading station. It is necessary to manually count the number of small boxes between the two (accurate to the number of strips), and insert an empty package object at the head of the "box barcode package queue" according to the number of strips (rounded up) for workstation alignment.
