Abstract
Container washing apparatus arranged for controlling the handling of the labels as they detach from the containers and for collecting the labels in spaced zones which are in communication through a system of transfer passages and baffles so that fluid flow directing nozzles will be effective to move the labels in an orderly and substantially non-turbulent manner to an outlet connected to apparatus for separating out the labels and returning the washing solution for reuse.
Claims11
Label removal apparatus for washing machines for containers bearing removable labels and for removing the detached labels from the machine, comprising:
- a washing solution containing compartment formed by and between side walls and walls transverse to said side walls;
- guide means extending downwardly in said compartment;
- label collecting trough means connected to said guide means and spaced above the bottom of said compartment, said guide means directing labels into said trough means, container conveying means movable through said compartment in descending and ascending paths outside of said guide means so as to have a path of travel beneath said trough means from the descending path to the descending path;
- an assembly of baffle means spaced below the path of travel of said conveyor means and above the compartment bottom to define a bottom space below said trough means;
- washing solution and label transfer passage means forming a communication between said trough means and said bottom space;
- fluid directing nozzle means in said trough means adjacent said transfer passage means to create a flow current for moving washing solution burdened with labels from said trough through said transfer passage means into said bottom space, and outlet means for washing solution burdened with labels connected into said bottom space.
Label removal apparatus for washing machines for containers bearing adhesively applied labels and for removing the labels from the containers and from the apparatus, comprising:
- at least one washing solution containing compartment open at the top, closed at the bottom and defined between side and transverse walls of said machine;
- container conveyor means following a path extending downwardly into said compartment from the top thereof and having a return path after forming a bottom loop above the compartment bottom, said conveyor including track means, chains following said track means, and container carriers having open ended pockets to receive the containers;
- guide means extending along said conveyor track means and around the return bottom loop and forming a label collecting trough in the bottom loop;
- transfer passage means opening between said bottom loop label collecting trough and the bottom of said compartment;
- an outlet for washing solution and entrained labels from the bottom of said compartment;
- washing solution flow directing means in said label collecting trough and in said compartment bottom below said trough, said washing solution flow directing means in said collection trough flushing the labels accumulating in said trough through said transfer passage means toward said compartment bottom through said transfer passage means, and baffle means adjacent said trough and passage forming means, said flow directing means in said compartment below said baffle means flushing the labels toward and into said compartment outlet and said baffle means being in position to substantially suppress the washing solution currents from rising above said compartment bottom and thereby reducing the migration of labels away from the area of said compartment bottom and said compartment outlet.
