Transverse lane labeling method and labeller
View Patent ↗A method for applying labels on articles, which are guided in parallel lanes, for which in each case a row of labels is dispensed by a label dispenser from a backing, taken up by a transfer path guided transversely over the lanes and transferred in a transfer step onto the articles, the transfers step comprising the moving of a lifting tool, extending along a section of the transfer path onto article lanes for pressing the labels onto the articles and the return of the lifting tool into its starting position. The dispensed labels are taken up at a point of the transfer path, which is at a distance from the lifting tool, and the dispending of a row of labels is commenced before the step of transferring a previous row of labels is concluded.
1. A method for the multi-lane and multi-row application of labels on articles which are guided in parallel article lanes, the method comprising the steps of:
dispensing a row of labels by a label dispenser, disposed at a side of the lanes, from a backing such that the dispensed row of labels is taken up by a transfer path guided transversely relative to the lanes; and
transferring the dispensed row of labels by a transfer device from the transfer path to the articles, the step of transferring comprising the steps of:
moving a lifting tool extending along a section of the transfer path onto the article lanes for pressing the labels onto the articles; and
returning the lifting tool into a starting position thereof;
wherein the dispensed labels are taken up at one point of the transfer path, which is at a distance from the lifting tool, and the step of dispensing of a row of labels is commenced before the step of transferring a previous row of labels is concluded, with the time of starting the dispensing of a row of labels being determined as a function of:
a transporting path of the labels from a taking-up point on the transfer path up to a point at which the labels reach the lifting tool,
speed of the transfer path, and
speed of the lifting tool.
2. The method of claim 1 , further comprising the step of optimizing the time at which the dispensing of a row of labels is commenced, so that the time between the return of the lifting tool into its starting position and the arrival of a leading label of the row of labels at the lifting tool is minimized.
3. The method of claim 1 , further comprising the steps of:
measuring the speed of the lifting tool and adjusting the time at which the dispensing of a row of labels is commenced as a function of a preceding measurement of the speed of the lifting tool.
4. The method of claim 1 , further comprising the step of continuously driving the backing and the transfer path with driving speeds thereof in the same ratio as center-to-center distances of the labels on the backing and lateral center-to-center distances of the article lanes.
5. The method of claim 1 wherein the transfer path comprises first and second belt arrangements positioned end to end, and wherein the method further comprises moving the row of labels with the first belt arrangement to the second belt arrangement.
6. The method of claim 5 wherein the step of dispensing a row of labels comprises dispensing the row of labels onto the first belt arrangement.
7. The method of claim 6 wherein the first belt arrangement is oriented at an angle with respect to the second belt arrangement such the that first and second belt arrangements are not coplanar.
8. A method for multi-lane application of labels onto articles that are guided in parallel article lanes, the method comprising the steps of:
a) dispensing a row of labels by a label dispenser from a backing and onto a transfer path;
b) transferring the dispensed row of labels from the transfer path to the articles, wherein step b) comprises moving a lifting tool, which extends along a section of the transfer path, relative to the article lanes to press the row of labels onto the articles, and returning the lifting tool to a starting position thereof; and
c) repeating steps a) and b) such that step a) is commenced before the step of returning the lifting tool is concluded in connection with step b) for the preceding row of labels.
9. The method of claim 8 further comprising optimizing time at which the dispensing of a row of labels is commenced, so that time between the return of the lifting tool into its starting position and arrival of a leading label of the row of labels at the lifting tool is minimized.
10. The method of claim 8 further comprising measuring speed of the lifting tool, and adjusting a time at which the dispensing of a row of labels is commenced as a function of a preceding measurement of the speed of the lifting tool.
11. The method of claim 8 further comprising continuously driving the backing and the transfer path with driving speeds thereof in the same ratio as center-to-center distances of the labels on the backing and lateral center-to-center distances of the article lanes.
12. The method of claim 8 wherein the transfer path comprises first and second belt arrangements positioned end to end, and wherein the method further comprises moving the row of labels with the first belt arrangement to the second belt arrangement.
13. The method of claim 12 wherein step a) comprises dispensing the row of labels onto the first belt arrangement.
14. The method of claim 13 wherein the first belt arrangement is oriented at an angle with respect to the second belt arrangement such the that first and second belt arrangements are not coplanar.
