A delabeler (11) provides a conveyor (12) which sandwiches a series of containers (13) to positively rotatably move such containers through a plurality of processing stations. A strip brush section (31) includes a series of stations (32-35) each including a plurality of rotating brushes (53-55) located within specific planes and operated to completely remove the container labels. A scrub brush section (101) includes a similarly constructed series of scrub brush stations (102-105) which completely remove adhesive residue from the containers. A series of stations (27, 28, 100, 106) spaced throughout the delabeler provide a series of vertically spaced pulsating jets (29) of non-caustic fluid to the containers while an initial drenching station (25) preconditions the labels prior to further processing and a drying station (107) provides a completely dry and clean container following the delabeling.
A delabeler for removing one or more labels and associated adhesive from a container, comprising means to move a series of the containers through a plurality of processing stations, a strip brush station including a plurality of first brushes each including a plurality of circumferentially spaced, radially extending coarse bristles rotating about an axis spaced adjacent to said moving means and support means connected to said first brushes to position said coarse bristles against each moving container to remove the label, and a scrub brush station including a plurality of second brushes each including a plurality of circumferentially spaced, radially extending fine bristles having a greater flexibility than said coarse bristles and rotating about an axis spaced adjacent to said moving means and support means connected to said second brushes to position said fine bristles against each moving container to remove the adhesive.
A delabeler for use with labeled containers, comprising means to move a series of the containers through at least one processing station, and a series of spaced fluid jets located adjacent to said moving means and operable to provide a series of spaced pulsating jets of non-caustic fluid to facilitate the removal of at least a portion of each label.
A delabeler for removing one or more labels from a container, comprising means to move a series of the containers through a plurality of processing stations, a plurality of label abrading stations with each station including first and second label abrading members each rotating about a generally horizontal axis, support means connected to support said first and second label abrading members in radially spaced relationship with respect to each other within each station to simultaneously engage said first and second abrading members against the moving containers to remove a portion of the label from each container, said first and second abrading member axes within one of said stations located in separate planes spaced from the separate planes containing said first and second abrading member axes of another station to substantially remove the label from the container.
A delabeler for removing one or more labels from a container providing a labeled base portion of a wide diameter and a labeled neck portion of a narrow diameter, comprising means to move a series of the containers through a processing station, first and second label abrading members each rotating about a generally horizontal axis, support means connected to said first and second label abrading members to position said first member axis in a first plane to engage and remove at least a portion of the label from the container neck portion and to position said second member axis in a second plane spaced from said first plane to simultaneously engage and remove at least a portion of the label from the container base portion.
A delabeler for removing labels from containers, comprising means to move a series of the containers through a processing station, a plurality of brushes each including a plurality of circumferentially spaced, radially extending bristles rotating about a generally horizontal axis spaced adjacent to said moving means, and support means connected to said brushes to radially space said brushes with respect to each other and to simultaneously engage the brushes against a moving container to remove at least a portion of the label from each container.
A delabeler for removing labels from containers, comprising means to move a series of the containers through a processing station, label abrading means including first and second label abrading members each rotating about an axis, support means connected to support said first and second label abrading members in spaced relationship along said moving means and in separate spaced planes to engage said first and second abrading members against different portions of the moving containers to remove at least a portion of the label from each container, and coupling means interconnecting said first and second abrading members for simultaneous rotation and including a pair of facing nipples fixedly connected to axial ends of said first and second abrading members for rotation therewith and a coupler providing spaced cavities each pivotally coupled to one of the nipples for rotation therewith to provide simultaneous rotation between said first and second abrading members while operating in separate spaced planes.
A delabeler for removing labels from containers, comprising means to move a series of the containers through a processing station including a rail to slidably support the containers in an upstanding position, movable means including a movable member operable to move along one side of said supporting rail while engaging the containers and stationary means including a stationary member extending along another side of said supporting rail and oppositely disposed with respect to said movable member to maintain a positive sandwiching engagement of the containers between said stationary member and said movable member to positively rotatably slide the containers along said supporting rail in response to said movable member, and a label abrading member rotating about a generally horizontal axis spaced adjacent said supporting rail and operatively stripping at least a portion of the label as the containers rotatably slide along said rail.
A delabeler for removing labels from containers, comprising means to move a series of the containers through a processing station including a rail to slidably support the containers in an upstanding position, movable means including a movable member operable to move along one side of said supporting rail while engaging the containers and stationary means including a stationary member extending along another side of said supporting rail and oppositely disposed with respect to said movable member to maintain a positive sandwiching engagement of the containers between said stationary member and said movable member to positively rotatably slide the containers along said supporting rail in response to said movable member, said stationary member is connected to a fixed support through a biasing spring operatively applying clamping pressure to the rotatably sliding containers, and a label abrading member rotating about an axis spaced adjacent said supporting rail and operatively stripping at least a portion of the label as the containers rotatably slide along said rail.
