Automatic hot melt adhesive depositing machine

Apparatus for automatically controlling the gravitational deposition of hot glue or the like dispensed from the nozzle of a dispensing machine and along a circuitous path upon the upper surface of a flat work-piece having an irregular curvilinear peripheral contour preparatory to its gluing assembly to a complemental member, the dispensing machine included electrical means for starting and stopping the dispensing flow of hot glue, comprising, in combination, a work table having a substantially horizontal support surface for seating the work-piece, means for positionally locating a work-piece upon said support surface, means for rotating said work table about a vertical axis, mechanism for supporting the nozzle of a hot glue dispensing machine vertically above a work-piece located on said support table, a cam fixed with respect to said work table and rotatable in unison therewith, a cam follower cooperative with said cam, said nozzle support mechanism comprising means slidably supporting said cam follower for rectilinear movement upon rotation of said cam, means for simultaneously initiating a rotative cycle of said work table and starting the flow of hot glue dispensd from the nozzle of the hot glue dispensing machine, and means controlled by the completion of a rotative cycle of operation of said work table for automatically stopping both the rotation of said work table and the flow of hot glue from said hot glue dispensing nozzle, said cam having the same peripheral contour as that of the work-piece upon which glue is to be deposited, and said work-piece locating means being operative to positionally constrain the work-piece so that its peripheral contour is in rotative registration with respect to the peripheral contour of said cam.
