Complete cutting station and method for separating packaging units
View Patent ↗A complete cutting station for separatingly cutting out packaging units from a film composite, the cutting station having a movable complete cutting tool configured for severing the film composite. The complete cutting station further comprises a conveying system having a plurality of conveyor elements for conveying a respective separated packaging unit, wherein each conveyor element in turn comprises a head portion for engaging with a respective packaging unit. The head portions of the conveyor elements may be movable between a first position in which the gripped packaging units are at a first distance relative to each other, and a second position in which the packaging units are at a second, smaller distance from each other or at least partially overlap in at least one spatial direction.
1. A complete cutting station for separatingly cutting out packaging units from a film composite, said cutting station comprising:
a complete cutting tool disposed for vertical movement and configured for severing said film composite, said cutting tool comprising using a plurality of cutting edges disposed to separatingly cut out a plurality of packaging units from a film composite, each cutting edge defining an outer contour of one of said plurality of packaging units; and
a conveying system having a plurality of conveyor elements for conveying a respective separated packaging unit, each said conveyor element comprising a head portion for engaging with a packaging unit, wherein said conveyor elements are disposed for vertical movement independent of said complete cutting tool and movable between a retracted and an extended position, and wherein each said head portion of said conveyor elements is located within the outer contour defined by one of said plurality of said cutting edges and laterally adjacent to the cutting edges in said retracted position;
wherein said head portions of at least some conveyor elements are movable between a first position in which packaging units that they engage are at a first distance to each other defined by said film composite, and a second position in which said packaging units are one of at a second smaller distance from each other or vertically overlap in at least one horizontal spatial direction; and wherein said conveyor elements are vacuum grippers, and said head portions are suction heads.
2. The complete cutting station according to claim 1 , wherein at least some of said conveyor elements are translationally movable and/or pivotable for moving the respective head portion of said at least some of said conveyor elements between said first position and said second position.
3. The complete cutting station according to claim 1 , wherein when each of said head portions of said plurality of conveyor elements are engaging said packaging units and at least some of said head portions are disposed in said second position of said respective head portions, at least some of said packaging units vertically overlap with at least two other adjacent packaging units.
4. The complete cutting station according to claim 1 , wherein said complete cutting tool is disposed vertically above the film composite during operation of said complete cutting station.
5. The complete cutting station according to claim 1 , wherein said complete cutting tool comprises a bridge connecting several cutting edges.
6. The complete cutting station according to claim 1 , wherein at least some of said conveyor elements are mounted to a gripper bridge and disposed for one of pivotal or translational motion.
7. The complete cutting station according to claim 1 , wherein said complete cutting station is a component in a packaging machine.
8. The complete cutting station according to claim 1 wherein said head portions hold and fix a position of said packaging units during separation of said packaging units from said film composite when said head portions are disposed in said first position.
