Bundled load corner edge protector cutting system

1. A non-contact cutter for a polymer corner protector disposed on a load, comprising:

an air manifold having an air passage between an inlet and an outlet and defining an air passage; and

a heating element disposed at least in part in the air passage, wherein the heating element is configured to heat a compressed gas in the air passage to a temperature greater than or equal to the melting temperature for the polymer and wherein the heated gas is discharged through the outlet to melt the polymer corner protector at a desired location to separate the corner protector at the desired location.

2. The non-contact cutter in accordance with claim 1 including a housing having the heating element disposed therein, the air manifold disposed at least in part in the housing.

3. The non-contact cutter in accordance with claim 2 wherein the housing has a generally L-shaped body having a back and a leg, and the heating element is disposed at least in part in the back and leg, wherein the air passage includes a portion configured to direct air to the back and leg for contact with the heating element.

4. The non-contact cutter in accordance with claim 1 wherein the heater is an electric heater.

5. The non-contact cutter in accordance with claim 1 wherein the heater is a ceramic heater.

6. The non-contact cutter in accordance with claim 1 wherein the cutter is disposed in a head and-wherein the head is movable toward and away from the polymer corner protector.

7. The non-contact cutter in accordance with claim 6 wherein the head is operably mounted to a rail for linear movement toward and away from the corner protector.

8. The non-contact cutter in accordance with claim 6 wherein the head is mounted for pivotal movement toward and away from the corner protector.

9. The non-contact cutter in accordance with claim 7 wherein the head is mounted to a carriage.

10. A non-contact cutter system for a polymer corner protector disposed on a load, the load resting on a horizontally oriented support, the system comprising:

a frame having an upper horizontally oriented rail;

at least one carriage mounted to the rail for horizontal movement along the rail;

a head mounted to each of the at least one carriages for vertical movement toward and

away from the carriage, the head including

an air manifold having an air passage between an inlet and an outlet, and

a heating element disposed at least in part in the air passage,

wherein each carriage is movable toward and away from the load and the head is movable toward and away from the carriage, the carriage and head being moved, toward the load to bring the head into proximity to the load and the heating element is configured to heat a compressed gas in the air passage to a temperature greater than or equal to the melting temperature for the polymer, and wherein the heated gas is discharged through the outlet to melt the polymer corner protector at a desired location to separate the corner protector at the desired location.

11. The non-contact cutter system in accordance with claim 10 wherein each head includes a housing having the heating element disposed therein, the air manifold disposed at least in part in the housing.

12. The non-contact cutter system in accordance with claim 11 wherein the housing has a general L-shape having a back and a leg, the heating element disposed at least in part in the back and leg, and wherein the air passage includes a portion configured to direct air to the back and leg for contact with the heating element.

13. The non-contact cutter system in accordance with claim 10 wherein the heater is an electric heater.

14. The non-contact cutter system in accordance with claim 10 wherein the heater is a ceramic heater.

15. The non-contact cutter system in accordance with claim 10 including two carriages, each carriage including a head and including two lower heads, each disposed on opposites sides of the load and at horizontally oriented support.

16. The non-contact cutter system in accordance with claim 15 wherein the lower heads include a housing having a heating element disposed therein, the air manifold disposed at least in part in the housing, and wherein each housing has a generally L-shaped body having a back and a leg, the heating element disposed at least in part in the back and leg, and wherein the air passage includes a portion configured to direct air to the back and leg for contact with the heating element.

17. The non-contact cutter system in accordance with claim 10 wherein the heater is an electric heater.

18. A method for non-contact cutting of a polymer corner protector disposed on a load, comprising:

positioning a non-contact cutter proximal to the polymer corner protector;

directing air through a manifold having an inlet and an outlet and defining an air passage;

heating the air within the manifold to a temperature greater than or equal to the melting temperature for the polymer;

discharging, the heated air from the manifold through the outlet, directing the heated air onto the polymer corner protector at a heated region; and

separating the heated polymer corner protector at the heated region.

19. The method in accordance with claim 18 wherein the air is heated by an electric heater.

20. The method in accordance with claim 18 wherein the non-contact cutter is positioned in a head and the head is moved to a position proximal to the corner protector for heating.
