Guarantee for correctly labelled boxes with correct weight.
The speed is high in the packing departments when the boxes are packed, sealed, weighed and labelled, so the risk for errors is evident. The errors may be of various kinds; the weight may be incorrect, the barcode may be illegible, the sealing-label may be placed wrong or there may be divergences between the text on the label and the content of the box.
Scanvaegt's weighing and labelling station eliminates all these errors – in addition to weighing and labelling the box, it also controls, that the weight as well as the information on the label is correct, that the sealing label is placed correctly and the the barcode is clear and readable. In case the box deviates from the specifications, it will be rejected out to a separate conveyor for re-packaging.
One system - multiple functions
The weighing and labelling station consists of:
- label applicator for application of the sealing label
- colour scanner for control of correctly applied sealing label
- belt weigher for weighing the box and industry computer for data-handling
- conveyor with centering unit
- label printer in stainless steel cabinet and label applicator
- scanner for quality control of labels and box.
Flexible label applicators
The label applicators of the system have have a flexible design, enablinng several placements of the label on the box; the label can be applied to the side of the box (on one or both sides), to the front or the end, on the top-side or across the edge of the box.
The applicators can also label boxes of different sizes and shapes at the same time.
The label applicators require only very short distance between the individual boxes – this, combined with their high application speed, enables the applicators to handle up to 20 boxes per minute (variable weight) and up to 40 boxes per minute (fixed weight).
Integrated control functions eliminate errors
When the box has been strapped, the sealing label is applied across the strap and the checked by a colour scanner.
The weighing and labelling station has a stop function, which ensures, that only one box at a time is on the weighing unit - this prevents errors in the weighing process. Once the box has been weighed, the industry computer couples the weight result to the order information, tranferred from the own IT-system. The box is then moved forward to the labelling unit, where weight and order information is printed on a label, which automatically is applied to the box.
Text and layout on the label is defined by the user.
Then a scanner reads the barcode on the label and checks, that it is readable and that the information complies with the data, generated in the industry computer at the registration of the weighing unit. |
