An inductive cap sealer () for sealing an inner seal over an opening () in container () includes a vented sealing head (). The sealing head () contains an induction coil () for producing an electromagnetic field when energized by a power supply. Field focusing elements () contain the coil () and direct the electromagnetic field to a sealing region beneath the sealing head (). The housing () has a central inlet vent () flanked by two outlet vents () aligned with a vent plate () inside the housing () having a plurality of small openings () which allow a fan () to blow cooling air through the sealing head from only one side of the sealing head () in a generally U-shaped flow pattern, preferably from the side opposite the sealing region. The field focusing elements () are spaced to allow the cooling air to flow around the field focusing elements () and past the coil ().

U-flow ventilated sealing head

An inductive cap sealer for sealing an inner seal over an opening in a container includes a vented sealing head. The sealing head contains an induction coil for producing an electromagnetic field when energized by a power supply. Field focusing elements contain the coil and direct the electromagnetic field to a sealing region beneath the sealing head. The housing has openings and the field focusing elements are spaced to allow cooling air to flow around the field focusing elements and past the coil.

Ventilated sealing head for induction sealer

A sealing head for an inductive cap sealing apparatus includes a outer housing containing a coil bobbin supporting a wire coil wound about a magnetic isolator. The coil bobbin and the magnetic isolator can be axially repositioned independently to vary the magnetic field with respect to a container being sealed placed below the sealing head. The housing has a pair of axial apertures containing spring and push rod assemblies connected to a cap plate. The cap plate is spring loaded away from the outer housing so as to clamp the cap and/or seal against the container being sealed.

Adjustable cap sealer head

A cap sealing unit for securing foil-polymer laminate innerseals to containers has an air cooled electronics cabinet that may be sealed in accordance with NEMA 4 standards. Heat sinks in the bottom of the electronics cabinet and the top of the sealing head are cooled by two external, wash-down safe fans disposed between the cabinet and the sealing head. The fans draw air in opposite directions, one toward the cabinet and the other toward the sealing head. The cap sealer can be operated with interchangeable flat or tunnel sealing heads of various sizes and coil windings that can be connected to the power supply with plug-in shielded connector assemblies.

Spray washable air cooled cap sealer

A control system for an industrial inverting type power supply is disclosed which provides for both operational control and a diagnostic capability for the power supply. The operational control aspects includes measuring and displaying a plurality of operational signals from within the power supply, and for providing several automatic modes of operation for the power supply. The diagnostic aspects of the control system include measuring and displaying a plurality of diagnostic values, particularly the measurement of several waveform characteristic values of the switching waveform of the power supply. Other diagnostic capabilities include a set of remote inputs, each of which, when activated, triggers an entry into a history table, thereby maintaining a record of remote input activations. Each remote input may also be configured with a descriptive message to be displayed on an operator display and a code which specifies the action that is to be taken by the control system when that remote input is activated. A short detection circuit is also included which operates when the power supply is stopped to test the switching elements of the power supply for shorts.
