Abstract

An apparatus and method for inhibiting the peeling of labels from a web is disclosed. A web with a plurality of labels is pulled towards a peeling edge. An antenna examines at least one of the labels. Based at least in part on the antenna'"'"'s examination of at least one label, one or more of a peel inhibiting device and a peeling edge is moved towards or away from the other. The combination of the edge and device forms a rounded surface over which the web and labels are pulled. As the web and label(s) pass across the combination of the edge and device, the separation of at least one of the labels from the web is inhibited.

Claims

1. A peel inhibiting apparatus for inhibiting peeling of labels from a web, said apparatus comprising:

a peeling edge including an elongated acute corner surface and a first half-cylinder bar having a first radius, said elongated acute corner surface configured to separate said labels from said web when said web is pulled across said elongated acute corner surface; and

a peel inhibiting device including a second half-cylinder bar having a second radius, wherein at least one of said peeling edge and said peel inhibiting device is configured to move towards the other so that said first and second half-cylinder bars form a peel inhibiting surface, said peel inhibiting surface configured to prevent said labels from separating from said web when said web is pulled across at least a portion of said first and second radii of said first and second half-cylinder bars.

2. The apparatus of claim 1, wherein said peel inhibiting device includes a rounded surface and a cavity, said peeling edge capable of residing within said cavity,

wherein said device and said edge form said peel inhibiting surface when said peeling edge is located within said peel inhibiting device.

3. The apparatus of claim 1, wherein said peel inhibiting device is configured to be driven towards and/or away from said peeling edge based on a determination of whether one or more of said labels has been properly encoded.

4. The apparatus of claim 3, wherein said determination is made by the following steps:

transmitting an encode signal to one or more of said labels;

transmitting a read signal to one or more of said labels, said labels transmitting a response signal when said read signal is received at one or more of said labels;

receiving said response signal; and

verifying whether said response signal includes one or more indications of proper encoding of one or more of said labels.

5. The apparatus of claim 3, wherein said peel inhibiting device is configured to be linearly driven towards and/or away from said peeling edge by at least one of a solenoid and a spring.

6. The apparatus of claim 1, wherein said peeling edge is configured to be driven towards and/or away from said peel inhibiting device based on a determination of whether one or more of said labels has been properly encoded.

7. The apparatus of claim 6, wherein said determination is made by the following steps:

transmitting an encode signal to one or more of said labels;

transmitting a read signal to one or more of said labels, said labels transmitting a response signal when said read signal is received at one or more of said labels;

receiving said response signal; and

verifying whether said response signal includes one or more indications of proper encoding of one or more of said labels.

8. The apparatus of claim 6, wherein said peel inhibiting device is configured to be linearly driven towards and/or away from said peeling edge by at least one of a solenoid and a spring.

9. A method for inhibiting peeling of one or more labels from a web, said method comprising:

pulling said web towards a peeling edge, said web including a plurality of said labels adhered to said web, said peeling edge including an upper surface; and

inhibiting separation of one or more of said labels from said web by forming a peel inhibiting surface, at least a portion of said peel inhibiting surface positioned between said upper surface of said peeling edge and said web.

10. The method of claim 9, wherein said inhibiting step includes moving a peel inhibiting device to said peeling edge to form said peel inhibiting surface.

11. The method of claim 10, wherein said peeling edge includes a first half-cylinder bar forming a first radius and said peel inhibiting device includes a second half-cylinder bar forming a second radius, said first and second bars configured to form said peel inhibiting surface when said second bar is driven to said first bar.

12. The method of claim 9, further including examining one or more of said labels for proper encoding.

13. The method of claim 12, wherein said examining step includes:

transmitting an encode signal to one or more of said labels;

transmitting a read signal to one or more of said labels, said labels transmitting a response signal when said read signal is received at one or more of said labels;

receiving said response signal; and

verifying whether said response signal includes one or more indications of proper encoding of one or more of said labels.

14. The method of claim 13, wherein said inhibiting step occurs when one or more of said labels are determined to not have proper encoding during said examining step.

15. A method for inhibiting peeling of one or more labels from a web, said method comprising:

pulling said web towards a peeling edge, said web including a plurality of said labels adhered to said web; and

inhibiting separation of one or more of said labels from said web by forming a peel inhibiting surface at said peeling edge, wherein said inhibiting step includes retracting said peeling edge within a peel inhibiting device to form said peel inhibiting surface, said peel inhibiting device including a rounded surface and a cavity.

16. A system for applying labels, said system comprising:

an antenna configured to examine at least one of said labels adhered to a web for proper encoding; and

a peel inhibit apparatus configured to separate properly encoded labels from said web and to prevent improperly encoded labels from said web based on an examination of said labels by said antenna, said peel inhibit apparatus including a peel inhibiting device and a peeling edge, said peeling edge including an upper surface,

wherein at least one of said device and said edge is configured to move towards the other in order create a rounded surface capable of preventing improperly encoded labels from separating from said web, at least a portion of said rounded surface being positioned between said upper surface of said peeling edge and said web.

17. The system of claim 16, wherein said device is configured to move towards said edge in order to create said rounded surface.

18. The system of claim 16, wherein said antenna is configured to encode said labels with identification information.

19. A system for applying labels, said system comprising:

an antenna configured to examine at least one of said labels adhered to a web for proper encoding; and

a peel inhibit apparatus configured to separate properly encoded labels from said web and to prevent improperly encoded labels from said web based on an examination of said labels by said antenna, said peel inhibit apparatus including a peel inhibiting device and a peeling edge,

wherein at least one of said device and said edge is configured to move towards the other in order create a rounded surface capable of preventing properly encoded labels from separating from said web, wherein said edge is configured to move towards said device in order to create said rounded surface.
