Abstract
An apparatus for automatic cleaning of silk screen printing frames, comprising a chamber (1), a vertical nozzle holder (4) being adapted to move in a horizontal direction throughout the entire width of said chamber (1) and a plurality of nozzles (5) arranged in separate groups and serving to spray a variety of liquids, being pumped from reservoirs (6, 7, 8) associated with said chamber (1), successively onto said frame (2). The reservoirs 6 and 7 are provided with rotating lids 9, 10 repectively which can assume overlapping positions to prevent the flow of return fluid into the reservoirs or generally upright positions to direct the flow of return liquid into the respective reservoir.
Claims3
A silk screen printing frame cleaning apparatus comprising:
- a closeable chamber in which a silk screen printing frame is adapted to be held;
- a plurality of liquid applying means mounted in said chamber and movable with respect to said frame;
- a plurality of means for containing liquids to be applied by said liquid applying means to the frame;
- means for conveying the liquids from one of said containing means to an associated one of said plurality of applying means;
- means for returning applied liquid to the containing means from which said applied liquid was conveyed;
- said plurality of liquid containing means being disposed below said chamber and formed by walls of said apparatus in cooperation with a series of partitions of decreasing height, each of said liquid containing means having a substantially planar lid having an upper and lower end, each of said lids being pivotally attached intermediate said upper and lower ends and adjacent to an upper edge of one of said partitions, the lower end of each of said lids overlapping an adjacent lid, said closed lids forming a downwardly sloping surface whereby the liquids flow down said sloping surface and into a containing means whose associated lid is open.
