Abstract

There is disclosed a device for applying a liquid adhesive onto the surface of bottles moving in upright seriatim fashion on a horizontal moving conveyor at an adhesive applying station. The device includes a container for liquid adhesive and a pivoted frame supported over the container which supports a beveled feed wheel on an inclined shaft driven by its connection to an electric motor. The beveled feed wheel rotates partly submersed in the adhesive and engages a cylindrical applicator roller freely rotatable on a vertical axis at the applying station. The outer periphery of the roller is comprised of a porous, resilient layer, e.g. a spongy urethane layer which receives adhesive from the beveled facing of the feed wheel. The beveled facing of the latter is non-porous and smooth, e.g. a steel facing. The roller is properly loaded with adhesive transferred by the feed wheel and is also driven by the wheel in a direction corresponding with movement of the bottles in the applying station; whereat the roller surface layer engages the bottle surface and applies adhesive thereto.

Dependent claims

The combination comprising

a horizontal power driven conveyor span supporting a plurality of bottles in vertical upright position in a spaced apart series for movement in a single file succession past an adhesive applying station,
a lateral frame at said applying station,
an adhesive application device supported on said frame comprising
a container for a body of liquid adhesive supported on said frame,
a generally horizontal support means pivotally connected to said frame overlying said adhesive body in said container and rotatable between an active adhesive applying position and a rotated remote position,
a feed wheel including a beveled outer peripheral surface,
a shaft connected to said wheel for rotation of the latter about its central axis, said shaft being supported in a vertically inclined position on said horizontal support means, said feed wheel being similarly inclined in adhesive applying position for rotation of a portion of its peripheral surface in the adhesive body,
a motor drive means mounted on said support means and connected to rotate said shaft,
an applicator roller including a substantially cylindrical outer peripheral surface and a central vertical shaft supporting said roller for free rotation, said vertical shaft being rotably supported on said horizontal support means, and
a support for said vertical roller shaft connected to said overlapping pivotal horizontal support means to maintain the peripheral surface of said roller in running engagement with the beveled surface of the feed wheel and engageable while in the active adhesive applying position with the exterior surface of bottles at the adhesive applying station.
