Stand-up membrane roofing induction heating tool

摘要

A portable induction heating tool is provided as a membrane roofing tool for use in sealing anchor plates with a heat-activated adhesive to a membrane roofing member. The tool uses two different audible tones so two tools can be used simultaneously on a single roof, while allowing a user to easily distinguish between the operation of both tools. The main housing containing electronics is weather-tight, and requires no forced-cooling devices. The controller automatically performs data logging functions, such as counting the number of anchor plates per job or per day that have been properly placed, counting the number of activation events for a tool's life, tracking the number of faults which occur as the tool is being used, and the controller can identify the type of fault that occurs during operation of the tool. The controller also stores energy setting changes in memory.

主权项

1. An induction heating apparatus for initiating a series of heating cycles of activation followed by deactivation, comprising:
a lower base portion; a middle body portion; a power supply, coil driver circuit, and controller having a processing circuit, positioned within at least one of said body portion and said base portion; and an induction coil operatively connected to the power supply via the coil driver circuit for activation thereof, the induction coil positioned in said base portion; wherein said processing circuit is configured to log data for multiple cycles of activations of said induction coil and detect the occurrence of at least one predetermined fault condition during operation of the apparatus, and thereafter identify the type of fault condition detected.
