Proceeding and arrangement to apply labels
A method and an arrangement to apply labels on marking objects which are transported on a track. By only two swinging arms, the output printed label is transported away from the label printer, in a first direction of travel, so that the adhesive side of the label is facing the first direction of travel of the label applicator plate, and in an opposite second direction of travel, so that the printed side of the printed label is faces the second direction of travel of the label applicator plate. Continued motion actuation of the label applicator plate by turning the swinging arm carrying the applicator plate and, where appropriate, rotation of the applicator plate provides transportation of the label to and delivery of the label at and application of the label on the marking object with the adhesive side of the label facing the marking object.
1. A label applicator for applying labels on objects that are movable along a conveyor track, comprising:
a label printer;
a label applicator plate;
a primary swinging arm; and
a secondary swinging arm;
wherein the secondary swinging arm carries the label applicator plate; the primary swinging arm and the secondary swinging arm are articulatedly turnable around a common pivot joint; the primary swinging arm is carried by the label applicator and is turnable 360° around a rear pivot joint; and the secondary swinging arm is turnable about the common pivot joint by at least 200°, and wherein pivots of the common pivot joint and rear pivot joint extend substantially vertically.
2. The label applicator of claim 1 , wherein the label applicator plate is resiliently freely turnable around a third pivot joint.
3. The label applicator of claim 1 , wherein the primary and secondary swinging arms are vertically displaced from each other.
4. The label applicator of claim 1 , wherein the label applicator plate is configured to operate by suction.
5. The label applicator of claim 4 , wherein the label applicator plate operates by vacuum or by fan.
6. A label applicator for applying labels on objects that are movable along a conveyor track, comprising:
a label printer;
a label applicator plate;
a primary swinging arm; and
a secondary swinging arm;
wherein the secondary swinging arm carries the label applicator plate; the primary swinging arm and the secondary swinging arm are articulatedly turnable around a common pivot joint; the primary swinging arm is carried by the label applicator and is turnable about a rear pivot joint; and the secondary swinging arm is turnable about the common pivot joint, and wherein pivots of the common pivot joint and rear pivot joint extend substantially vertically.
7. The label applicator set forth in claim 6 , wherein the conveyor track is constructed to move along a direction that is substantially perpendicular to the common pivot joint and the rear pivot joint.
