On-line laser coding Weighing system uses a laser marking machine (laser coding machine) to print a two-dimensional code for a single bottle product on the packaging line of the production line. Through the control of field software, after each single bottle with a specified specification and quantity (for example, 4 bottles per box) is printed, it enters the weighing conveyor metering system, and then the bar code printer automatically prints the box code label, which is pasted when packing, forming the relevant data of this box.

When the weighing system of laser dynamic coding and marking machine is packing, an industrial fixed collector is placed at the back end of the box sealing machine to scan and collect the bar codes after sealing. After scanning the bar codes of the specified number of boxes (for example, 75 boxes per tray), the bar code printer will automatically print the label of the tray and paste it at the designated position to form the relevant data of this tray.

The control system adopts color image display and "touch screen computer integrated workstation" to control respectively. And networking by means of communication, realizing the coordination of data acquisition, processing and feedback control. Achieve reasonable, timely, accurate and perfect automatic control of the whole production process.

The industrial computer adopts modularized real-time monitoring instrument hardware, and uses the powerful function of programmable logic controller (PLC) to realize full-automatic control, "monitoring of weighing and metering system", "automatic control of stacking unit", "recording and saving production data" and "networking with upper computer 485 or TCPIP communication and data transmission".

Action flow of laser dynamic

The realization method of code Measurement system association of laser on-line coding and assigning machine

1. On-line laser inkjet printer weighing system production line is equipped with on-site industrial control, loading industrial control computer, on-site coding related software, PLC controller, two-dimensional code identification system, weighing conveyor, handheld wireless terminal, board card, etc., which are integrated into one. Coordinate the programmed actions of each part of hardware, and the distribution, correlation and arrangement of field data.

2. On-line laser marking machine metering system A laser marking machine is installed in the front of the packaging line of the production line, and the single bottle on the assembly line is printed with anti-channeling code, which is generated by software encryption.

3. The metering system of the online laser code printer is equipped with a chain clamping device after the laser code spraying is completed, so that the products in each box can be separated by a certain distance to ensure the accuracy of data association.

4. The weighing system of online laser code printer is equipped with a bar code printer to print the bar code of each box after the laser code spraying is completed, which forms an association with a single bottle at this time. Printed labels are placed on every specified quantity of products.

5. The manual packaging of the weighing system of the online laser inkjet printer will be carried out in groups, and each group will package each box of products. When it is placed in the assembly line again, it should be placed in sequence, and each box should be kept at a certain distance. Products damaged in the packaging process will be replaced or centralized.

6. When the products of the weighing system of the online laser marking machine are packed, the attached bar code label of the outer box is pasted to the designated position, and the industrial fixed collector is placed at the back end of the sealing machine, and the bar codes are scanned and collected in turn. The customer display screen at the scene will show the number of full pallets and the current scanned and collected quantity.

7. On-line laser bottle capping machine weighing system When the bar code of the specified number of cartons is scanned, the bar code printer automatically prints the label of the tray and pastes it at the designated position to form the relevant data of this tray. Export the related data of each batch and upload it to the software database.
