A labeling machine in a container filling plant, said container filling plant comprising:
- a first conveyor arrangement being configured and disposed to convey empty containers to be filled;
- a container filling machine being configured and disposed to receive empty containers from said first conveyor arrangement and fill containers;
- a second conveyor arrangement being configured and disposed to receive filled containers from said container filling machine and convey filled containers to be closed;
- a container closing machine configured to receive filled containers from said second conveyor arrangement and close filled containers;
- a third conveyor arrangement being configured and disposed to receive closed containers from said container closing machine and convey closed containers to be labeled;
- said labeling machine configured to receive closed containers from said third conveyor arrangement and place labels onto containers, said labeling machine comprising:
- a label supply configured to supply uncut labels in strip form;
- a feeding arrangement configured to receive uncut labels in strip form from said label supply and supply uncut labels in strip form;
- a cutting station configured to receive uncut labels in strip form from said feeding arrangement and cut uncut labels into individual labels, said cutting station comprising:
- a rotatable vacuum drum comprising:
- a plurality of vacuum openings in an outer circumferential surface thereof configured to be in flow communication with a vacuum source;
- at least one anvil disposed on said vacuum drum and comprising an outer surface radially extending beyond said outer circumferential surface of said vacuum drum;
- said at least one anvil longitudinally extending parallel to the axis of rotation of said vacuum drum;
- a cutting arrangement comprising:
- a knife shaft comprising an axle and at least one knife extending from said axle;
- said axle comprising an axis of rotation substantially parallel with said axis of rotation of said vacuum drum and configured to provide movement of said at least one knife;
- said at least one knife having edges extending away from said axle of said knife shaft and having an axial length substantially equal to the axial length of a corresponding one of said at least one anvil;
- said at least one knife configured to cooperate with its corresponding anvil to cut uncut labels in strip form into individual labels;
- a knife gap adjusting apparatus comprising:
- a movable stop comprising at least one adjusting surface;
- an adjusting apparatus configured to cooperate with said axle of said knife shaft and to rest against said adjusting surface of said movable stop and move said at least one knife in a first direction and a second direction upon movement of said moveable stop;
- said adjusting apparatus and said adjusting surface being configured such that upon movement of said adjusting surface in a first direction, said adjusting apparatus moves said at least one knife in said first direction, with respect to a stationary frame portion, increasing a minimum gap between said at least one knife and its corresponding anvil, during rotation of said at least one anvil with said vacuum drum;
- said adjusting apparatus and said adjusting surface being configured such that upon movement of said adjusting surface in a second direction, said adjusting apparatus moves said at least one knife in said second direction, with respect to said stationary frame portion, decreasing a minimum gap between said at least one knife and its corresponding anvil, during rotation of said at least one anvil with said vacuum drum;
- said at least one knife and its corresponding anvil, upon adjusting the desired minimum gap therebetween with said knife gap adjusting apparatus, being configured to cut uncut labels in strip form into individual labels during rotation of said vacuum drum;
- said labeling machine further comprising:
- a transfer drum configured to transfer cut labels from the outer surface of said vacuum drum to containers, during rotation of said vacuum drum;
- and
- a carousel configured to receive filled and closed containers from said third conveyor arrangement and dispose containers to receive cut labels from said transfer drum.
