Window component stock indexing

摘要

A stock supply station for use in a insulated glass unit component production line includes a plurality of rotatable sheet stock coils, an indexing mechanism, and an uncoiling mechanism. The indexing mechanism is coupled to the sheet stock coils for indexing a selected one of the sheet stock coils to an uncoiling position. The uncoiling mechanism selectively uncoils sheet stock from a sheet stock coil indexed to the uncoiling position to thereby provide sheet stock to a downstream processing station.

主权项

1. An insulated glass unit spacer production line, comprising:
a) a stock supply station comprising:
i) a plurality of rotatable sheet stock coils wherein each of said coils is mounted to a rotatable disk;ii) an indexing mechanism coupled to the sheet stock coils for indexing a selected one of the sheet stock coils to an uncoiling position;iii) a single uncoiling mechanism for selectively uncoiling sheet stock from a selective one of said plurality of sheet stock coils indexed to the uncoiling position by the indexing mechanism, said uncoiling mechanism further comprising a drive wheel for selectively engaging the rotatable disk at the uncoiling position to uncoil sheet stock and a selectively engageable engagement actuator for controllably moving the drive wheel into and out of engagement with the rotatable disk supporting said selected one of the plurality of coils to rotate said selected one of the plurality of coils to thereby provide sheet stock to a downstream processing station; b) a stamping station that stamps the sheet stock uncoiled from the selected one sheet stock coil; c) a roll forming station that receives stamped stock and forms rigid linearly extending spacer frame element having opposite side walls and a base wall; and d) a dispensing station for applying sealant material to external surfaces of the spacer frame element.
