Processing device and use thereof for the production of covers with a film which can be torn off
The invention relates to a processing device for covers ( 20 ), wherein processing stations are embodied as individual processing stations ( 47 ) provided with, respectively, one tool for one cover. Several of said stations work in parallel for the simultaneous processing of several covers. If need be, stations can also be used wherein several tools form groups which are functionally separate from each other. As a result, the processing precision and production speed of the objects can be increased.
1. A processing device comprising:
an advancing mechanism; and
a plurality of processing stations arranged in succession along an advancement direction,
wherein the advancing mechanism is adapted to advance a single row succession of objects along the advancement direction and comprises two conveyor belts arranged parallel to one another and driven in synchronism by a common drive, wherein a plurality of individual object receivers comprising opposed means for fixing an object about its perimeter are formed on the conveyor belts, and
wherein each of the plurality of processing stations is equipped to process a single object at a time, and
wherein the device is adapted to produce metal covers with tear-off foils, and
wherein one of the plurality of processing stations is a stamping processing station comprising an upper work tool and a lower work tool for the stamping of at least one hole.
2. The processing device according to claim 1 , wherein one of the plurality of processing stations is a drawing processing station for drawing the edge of the at least one hole, and
wherein one of said processing stations is a sealing processing station for applying a tear-off foil over the at least one hole.
3. The processing device according to claim 2 , wherein the sealing processing station is adapted to stamp at least one tear-off cover from a foil and place the at least one tear-off cover over the at least one hole.
4. A processing device according to claim 2 further characterized in that the sealing processing station is one equipped to apply a previously stamped out tear-off cover.
5. A processing device according to claim 2 further characterized in that the sealing processing station is connected in series with a stamping out station for the tear-off cover or in series with a station for taking a tear-off cover from a stack of such covers.
6. A processing station according to claim 5 further characterized in that the sealing processing station is connected in series with an adhesion station and/or a pre-warming station.
7. A processing device according to claim 1 , wherein one of the plurality of processing stations is a coining station for coining at least one tear-off foil, and
wherein one of the processing stations is a bending station for bending an edge of at least one hole.
8. The processing device according to claim 1 ,
wherein the plurality of processing devices further comprises a sealing processing station which is connected to the stamping processing station by way of the advancing mechanism.
9. The processing device according to claim 1 , wherein the opposed means are magnetic holding means.
10. A processing device comprising: an advancing mechanism; and
a plurality of processing stations arranged in succession along an advancement direction,
wherein the advancing mechanism is adapted to advance a single row succession of objects along the advancement direction,
wherein each of the plurality of processing stations is equipped to process a single object at a time,
wherein the advancing mechanism comprises two conveyor belts arranged parallel to one another and driven in synchronism by a common drive,
wherein a plurality of individual object receivers comprising opposed means for fixing an object about its perimeter are formed on the conveyor belts,
wherein the device is adapted to produce metal covers with tear-off foils,
wherein at least one of the plurality of processing stations is a stamping processing station comprising an upper work tool and a lower work tool for the stamping of at least one hole, said stamping processing station further comprising an upper work tool carrier and a plurality of columns for supporting the upper work tool;
wherein one of the plurality of processing stations is a drawing processing station for drawing the edge of the at least one hole, and
wherein one of the plurality of processing stations is a sealing processing station for applying a tear-off foil over the at least one hole.
