Abstract
A heater for drying printed material and the like is provided which includes a mounting frame for mounting the heater on a press and the like. The heater is movable on the mounting frame between operating and storage positions. A heat deflector assembly deflects heat away from the impression cylinder of the press. A heat lamp assembly is mounted on the heat deflector assembly and includes an enclosure with a pair of quartz tube, infrared heat lamps therein.
Claims12
In combination with a printing press having an impression cylinder and a path for workpieces comprising printed materials, the improvement of a heater for drying printed materials which comprises:
- (a) mounting means adapted for movably mounting said heater whereby said heater is transversely movable between operative and storage positions;
- (b) a heat lamp assembly connected to said mounting means and including:
- (1) an enclosure with upstream, downstream and top panels comprising reflective material and opposite ends;
- (2) a heat lamp extending between said enclosure opposite ends;
- and
- (c) a heat deflector assembly connected to said heat lamp assembly in a heat exchange relationship therewith, said heat deflector assembly being adapted to deflect heat from said heat lamp in a downstream direction away from said impression cylinder.
A heater, which comprises:
- (a) a mounting frame including:
- (1) first and second clevis legs positioned in transversely opposed relation;
- (2) a transverse guide bar extending between said clevis legs;
- (3) a stop collar slidably receiving said guide bar and positioned in proximity to said first clevis leg and having a set screw for securing said stop collar to said guide bar;
- (4) a slide tube pivotably and slidably receiving said guide bar;
- and
- (5) a pair of slide tube legs mounted on said slide tube and extending therefrom in parallel, spaced relation;
- (b) a heat deflector assembly including:
- (1) a main heat deflector panel mounted on said slide tube legs and having upper and lower ends, upstream and downstream faces and a central opening;
- (2) an exhaust fan mounted on said main heat deflector panel downstream face in communication with said central opening;
- (3) an auxiliary heat deflector panel connected to said main heat deflector panel and extending in a downstream direction from said main heat deflector panel downstream face in proximity to the main heat deflector panel upper end, said auxiliary heat deflector panel forming a dihedral angle with said main heat deflector panel;
- and
- (c) a heat lamp assembly including;
- (1) a heat lamp enclosure with upstream, downstream and top panels comprising reflective material and opposite ends;
- (2) a layer of insulation placed over said enclosure top panel;
- (3) a reflector panel placed over said insulation layer and comprising reflective material;
- (4) a transverse quartz tube heat lamp positioned in said enclosure and extending between said opposite ends thereof;
- and
- (5) said enclosure being mounted on said main heat deflector panel downstream face in proximity to the lower end thereof.
