The present invention relates to a method for marking identity codes. More specifically, the present invention relates to a method for marking identity codes on a cartridge.
Generally, cartridges have been used in various industries such as mining, chemical, construction, food processing, manufacturing and road construction etc. The cartridges are available in cylindrical shapes. The cartridges are used for storing materials. For effective tracking of every filled cartridge starting from the manufacturer to the end-user on a real-time basis throughout the supply chain or for tracking the last legal source of the cartridge, it is essential to mark each cartridge with a unique identification code and verify the marking of this code for quality check and/or verification of data integrity for serialization.
In the existing process, no unique identity code is marked, or the unique identity codes such as barcode/2D Code/QR code/human-readable data/Alphanumeric code/Alphabetic code are marked on the cartridges. The unique identity code includes identification information and/or other information regarding the cartridge. The printing location is not appropriate and not at the same distance from the edge of the cartridge. Hence, the marked identity code is not readable during online quality check and/or verification of data integrity for serialization by camera or any such automated equipment or scanning device. The code verification is done on the production line at substantial speed, resulting in the rejection of the cartridges.
Also, in existing methods, a camera system is installed to check the unique identity code on each cartridge while cartridges are moving. A sensor is used to sense the leading edge of the cartridge, the camera is triggered at a specific distance from this edge, so the unique identity code must be printed at the exact location on the cartridge, but in the existing process, there is a shift in this printing due to which the camera is unable to scan the identity code resulting into the rejection of these cartridges.
Also, due to the further processes, external impurities such as dust, oil, dirt, water etc., are present on the cartridges. Hence, the marked identity code is not readable during quality check and/or verification of data integrity for serialization, resulting in the rejection of these cartridges.
Also, existing cartridges have poor colour contrast between the unique identity code and the surface on which the unique identity code is marked. Hence, the marked code is not readable during quality check and/or verification of data integrity for serialization.
Further, one more challenge while scanning the unique identity code is that the cartridges tend to rotate around their own axes. Due to this rotation, the identity code loses its position and gets shifted on either side. Due to such a problem, the overhead scanning device or reading device cannot read the marked identity code.
Due to frequent rejection, the problems such as production loss, financial loss, reduction in the required quantity, risk of data mismatch in case of any malfunction and delay in delivery of the goods may occur. Hence, there is a requirement for a method for marking identity codes on a cartridge that can overcome one or more drawbacks of the existing methods.
An object of the present invention is to provide a method for marking identity codes on a cartridge.
An object of the present invention is to provide a method for marking identity codes on a cartridge, which provides a defined location for printing identity codes on the cartridge.
An object of the present invention is to provide a method for marking identity codes on a cartridge, which removes the external impurities from the surface of the cartridge.
Another object of the present invention is to provide a method for marking identity codes on a cartridge, which enables scanning devices to scan the identity codes marked on the cartridge efficiently for quality check and/or verification of data integrity for serialization.
Further object of the present invention is to provide a method for marking identity codes on a cartridge, which ensures accurate online reading or scanning or verification of the code to avoid rejection or production loss.
The present invention relates to a method for marking identity codes on a cartridge and online authentication scanning of identity codes on cartridges at a defined location on the cartridge with the help of an eye mark and better contrast and readability. The method involves marking unique identity codes multiple times on the cartridge so that the unique identity codes get clearly scanned by scanning devices to avoid rejection during quality check and/or verification of data integrity for serialization. Also, the method can provide a clear colour contrast between the identity codes and the surface of the cartridge to provide proper visibility of the identity codes.
At the first step, a polymeric film is selected for printing the identity codes based on the product or brand of the cartridge. In an embodiment, the polymeric film can be a High-Density Polyethylene (HDPE) or a Low-Density Polyethylene (LDPE) material or any other material, including paper. The polymeric film may have a white background thereon for providing a colour contrast between the background and the identity code thereon. The geometrical dimension of the polymeric film can be configured according to the geometrical dimensions of the cartridge.
The polymeric film has an eye mark marked on a definite location of the polymeric film. The eye mask is a black-coloured mark to enable external scanning devices (such as an optical sensor, cameras) to identify a start position of a portion on a packaging to be scanned. The scanning device (not shown in the figure) get triggered when the eye mark on the starting position is detected, and the scanning device scans the identity codes.
Further, an identity code is printed multiple times in two or more rows in an asymmetric manner in a definite location along the width direction of the polymeric film. Each identity code contains equal information regarding the cartridge (i.e. each identity code is equal). In an embodiment, the location of the identity codes is close to the centre of the cartridge along the length of the cartridge. The identity codes are marked on the cartridge from a predefined distance from the eye mark.
The identity codes are marked so that the botheration of non-scan ability of the identity code due to shifting in position and rotation of the cartridge around the axis of the cartridge is resolved. The identity code is a machine-readable code that stores the information data of the cartridge such as a batch number and/or manufacturing date and/or expiry date and/or a lot number and/or a manufacturing code and/or a unique identification number and/or any such information linked with the cartridge in an encrypted form and/or non-encrypted form.
The identity codes can be two-dimensional or quick response codes or data matrix codes or barcodes or a human-readable data or alphanumeric codes or alphabetic codes or numeric codes. In an embodiment, the unique identity codes are printed on the polymeric film by a solvent-based or water-based or UV curable ink or thermal transfer overprint or any other suitable print option for preventing smudging of the identity codes. In addition, the white background on the polymeric film may provide clear visibility between the black-coloured identity codes and the white background on the polymeric film.
In further step, the polymeric film is rolled along a length direction for configuring a hollow cylindrical body with edges/end attached to form a closing edge/end. The hollow cylindrical body may have two open ends.
In the next step, one of the open ends of the hollow cylindrical body is sealed with folded crimps or rolled crimps or wire ties or any other such sealing methods. Further, the material such as a chemical or a water gel or an emulsion or a slurry or a food item etc., is filled in the cartridge with the help of a manual/automatic/semiautomatic filling machine or any type of filling machine. In the end, the other open end of the hollow cylindrical body is sealed with folded crimps or rolled crimps or wire ties or glue or an adhesive tape such as a packing tape or a Teflon tape, or a staple machine etc. to form the cartridge.
After forming the cylindrical cartridge, the cartridge moves for further processes if necessary. The cartridge is carried for further processing on a conveyer. In these processes, external impurities may get deposited on the surface of the cartridges. To remove the external impurities such as dust, oil, dirt, and other external particles, a hot air blower can be configured over the conveyor. The hot air blower may remove external solid impurities by blowing the air over the surface of the cartridge. Further, the moisture or water particles deposited on the surface of the cartridge are removed by a 360-degree circular air knife or air curtain before scanning the identity codes. Further, the printed identity codes get scanned by two or more scanning devices (such as a camera) mounted over the conveyor.
