Abstract

A label applicator, system, and method for applying labels to curved sides of objects, such as cell culture dishes, is provided. In an aspect, the label applicator includes a body having a first side and a second side, the second side comprising a curved surface; a base; at least one first resilient member having a defined length between a first end and a second end; and at least one second resilient member engaging the body and the base, wherein the second end of the at least one first resilient member is configured to removably attach to a label and, when the label is in contact with the second end and an object, to apply a pressure to the label that increases as the at least one first resilient member and at least one second resilient member are compressed. The system may also include a label verifier and/or label verification system.

First claim

The invention claimed is:

1. A method of applying a label to a curved surface of an object, the method comprising:
providing a label applicator comprising:
a body having a first side and a second side, the second side comprising a curved surface, wherein at least one pathway extends from the first side of the body to the curved surface on the second side of the body;
a base positioned proximate to the first side of the body;
at least one first resilient member having a defined length between a first end and a second end, wherein the at least one first resilient member extends through the at least one pathway, the first end of the at least one first resilient member engages with the base, and the second end of the at least one first resilient member extends beyond the curved surface; and
at least one second resilient member engaging the body and the base,
wherein the second end of the at least one first resilient member is configured to removably attach to a label;

attaching the label to the second end of the at least one first resilient member;
moving the label applicator towards an object having a curved surface;
adhering the label to the curved surface using an increasing application force based at least on the first resilient member and the second resilient member, wherein the at least one first resilient member moves independently of the body such that pressure initially applied to the label as the label is attached to the second end compresses the second end toward the curved surface of the body, and wherein, upon the pressure causing the second end to reach the curved surface, further pressure compresses the body toward the base; and
detaching the label from the second end of the at least one first resilient member.

2. The method of applying a label to a curved surface of claim 1 , further comprising
scanning the label using a scanner; and
confirming that the object has been labeled.

3. The method of applying a label to a curved surface of claim 1 , further comprising
monitoring the increasing application force; and
responsive to monitoring the increasing application force, halting movement of the label applicator towards the object when the increasing application force exceeds a predetermined limit.

4. The method of applying a label to a curved surface of claim 1 , wherein the increasing application force is further based on:
a suction cup attached to the second end of the at least one first resilient member, and
a resilient surface attached to the second side.

5. The method of applying a label to a curved surface of claim 1 , wherein the at least one pathway comprises two channels defined by the body, the two channels positioned on opposite sides of a midpoint of the curved surface.

6. The method of applying a label to a curved surface of claim 1 , wherein the label applicator further comprises an adhesive member on the second end of the at least one first resilient member.

7. The method of applying a label to a curved surface of claim 6 , wherein the adhesive member is selected from the group consisting of a suction cup, an adhesive surface, a magnet, and a vacuum tube.

8. The method of applying a label to a curved surface of claim 1 , wherein the label applicator further comprises a resilient surface attached to the curved surface.

9. The method of applying a label to a curved surface of claim 8 , wherein the resilient surface is selected from the group consisting of a foam pad, a spring-loaded surface, and a bladder.

10. The method of applying a label to a curved surface of claim 1 , wherein the at least one first resilient member is selected from the group consisting of a spring and a pneumatic device.

11. The method of applying a label to a curved surface of claim 1 , wherein the at least one second resilient member is selected from the group consisting of a spring, a compressive polymer, a pneumatic device, foam, and a bladder.

12. The method of applying a label to a curved surface of claim 1 , wherein moving the label applicator towards the object is carried out with a movable arm that is configured to move the base of the label applicator.

13. The method of applying a label to a curved surface of claim 12 , wherein a step motor is operably connected to the movable arm and configured to move the movable arm in at least one plane.

14. The method of applying a label to a curved surface of claim 13 , wherein a pressure sensor is configured to monitor the increasing application force of the label applicator by the step motor and halt movement of the label applicator when a predetermined limit is exceeded.

15. The method of applying a label to a curved surface of claim 1 , further comprising capturing information on the label using a scanner.

16. The method of applying a label to a curved surface of claim 15 , wherein capturing information on the label is carried out after adhering the label to the curved surface of the object.

17. The method of applying a label to a curved surface of claim 15 , wherein capturing information on the label comprises using a scanner controller to sweep the scanner in a vertical direction to capture the information on the label.
