DETAILED DESCRIPTION OF THE INVENTION FIG.
1 generally illustrates an apparatus according to the present invention.
The inventive apparatus generally includes a rotating glue gun assembly 2 driven by a pulley assembly 4 which is powered by a drive assembly 6.
The gun and pulley assemblies 2 and 4 are secured upon a moving gun platform 46 which is supported and vertically movable by a vertical support assembly 10.
The support assembly 10 is vertically moved along its axis by a drive means 11 in order to move the gun assembly 2 between a glue applying position proximate an open end of a container 7 and a transition position.
The longitudinal axis of the support assembly 10 is aligned along the direction of linear movement of the gun assembly 2 when moved between the glue applying and transition positions.
This movement effects insertion and removal of the gun from the open end of the container.
The drive assembly 6 includes a motor 12 aligned such that the longitudinal axis of its drive shaft 20 extends in a direction parallel to the longitudinal axis of the vertical support assembly 10
