Blow-off sprocket

A can blow-off system comprising:

• a pin chain comprising a plurality of evenly spaced pin supports each adapted to support a can;
• a rotating toothed sprocket, said pin chain cooperatively mating with said sprocket over a portion of its circumference;
• a plurality of compressed air nozzles positioned on said sprocket, said nozzles spaced so as to match the spacing between said pin supports and each said nozzle synchronized with one of said pin supports as said pin support moves with said sprocket so as to deliver compressed air toward said pin support;
• each of said nozzles having a valving device and an air conduit connecting said nozzle to a distribution manifold for delivery of compressed air;
• whereby for each said pin support compressed air is delivered through one of said nozzles synchronized with said pin support in response to activation of said valving device so as to eject a can disposed on said pin support.

• a rotating toothed sprocket mounted on a shaft, said pin chain cooperatively mating with said sprocket over a portion of its circumference;
• a plurality of compressed air nozzles positioned on said sprocket, said nozzles spaced so as to match the spacing between said pin supports and each said nozzle synchronized with one of said pin supports as said pin support moves with said sprocket so as to deliver compressed air toward said pin support;
• each of said nozzles having a valving device and an air conduit connecting said nozzle to a distribution manifold for delivery of compressed air to each of said air nozzles independently;
• whereby for one of said pin supports compressed air is delivered through one of said nozzles synchronized with said pin support in response to activation of said valving device so as to eject a can disposed on said pin support.
