Label applying system
A label applying system includes a conveyance path for moving an item in a conveyance direction, and a label applying arm, including a free end with an associated tamp pad, the label applying arm linearly movable toward the conveyance path for applying a label to the moving item on the conveyance path. A connection between the tamp pad and the label applying arm comprises at least one rubber damper between the tamp pad and the label applying arm for enabling pivot of the tamp pad and absorbing impact force when the tamp pad contacts the moving item to apply the label to the moving item.
1. A label applying system, comprising:
a conveyance path for moving an item in a conveyance direction;
a label applying arm, including a free end with an associated tamp pad, the label applying arm linearly movable toward the conveyance path for applying a label to the moving item on the conveyance path;
wherein a connection between the tamp pad and the label applying arm comprises at least one rubber damper between the tamp pad and the label applying arm for enabling pivot of the tamp pad and for absorbing impact force when the tamp pad contacts the moving item to apply the label to the moving item.
2. The label applying system of claim 1 , wherein the connection comprises a structural plate rigidly connected to the free end of the label applying arm, and the at least one rubber damper interconnects the structural plate and the tamp pad.
3. The label applying system of claim 2 , wherein the at least one rubber damper includes a first end rigidly connected to the structural plate and a second end rigidly connected to the tamp pad.
4. The label applying system of claim 2 , wherein the at least one rubber damper comprises a first rubber damper interconnecting the structural plate and the tamp pad and a second rubber damper interconnecting the structural plate and the tamp pad, the second rubber damper spaced apart from the first rubber damper.
5. The label applying system of claim 4 , wherein an axis of each rubber damper is axially offset from an axis of the label applying arm.
6. The label applying system of claim 4 , wherein the first rubber damper includes a first central axis, wherein the second rubber damper includes a second central axis substantially parallel to the first central axis, wherein a plane in which both the first central axis and the second central axis lie runs substantially perpendicular to the conveyance direction.
7. The label applying system of claim 1 , wherein a shape of the at least one rubber damper changes when the tamp pad pivots.
8. The label applying system of claim 7 , wherein the at least one rubber damper bends when the tamp pad pivots.
9. The label applying system of claim 1 , wherein the at least one rubber damper comprises a cylindrical damper.
10. The label applying system of claim 1 , wherein the at least one rubber damper is formed of a rubber material having a durometer of between 40 A and 60 A.
11. The label applying system of claim 1 , wherein the at least one rubber damper is configured such that it will axially compress no more than 15%.
12. The label applying system of claim 1 , wherein a total mass of all rubber dampers that interconnect the label applying arm to the tamp pad is less than 1.30 ounces.
13. The label applying system of claim 1 , wherein the label applying arm is moved toward the conveyance path at a set operating speed and a total energy dissipation capacity of all rubber dampers that interconnect the label applying arm to the tamp pad is at least as great as a kinetic energy of the moving label applying arm.
14. A label applying system, comprising:
a label applying arm, including a free end with an associated tamp pad, the label applying arm having a length and being linearly movable in a direction along the length for applying labels;
wherein a connection between the tamp pad and the label applying arm comprises at least one rubber damper between the tamp pad and the label applying arm for enabling pivot of the tamp pad when the tamp pad contacts the moving item to apply the label to the moving item.
15. The label applying system of claim 14 , wherein the connection comprises a structural plate rigidly connected to the free end of the label applying arm, the at least one rubber damper interconnecting the structural plate and the tamp pad.
16. The label applying system of claim 15 , wherein the at least one rubber damper includes a first end rigidly connected to the structural plate and a second end rigidly connected to the tamp pad.
17. The label applying system of claim 14 , wherein an axis of the at least one rubber damper is axially offset from an axis of the label applying arm.
18. The label applying system of claim 14 , wherein the at least one rubber damper bends when the tamp pad pivots.
19. The label applying system of claim 1 , wherein the at least one rubber damper is formed of a rubber material having a durometer of between 45 A and 55 A.
20. The label applying system of claim 14 , wherein the label applying arm is moved at a set operating speed and a total energy dissipation capacity of all rubber dampers that interconnect the label applying arm to the tamp pad is at least as great as a kinetic energy of the moving label applying arm.
