| (54) | Dispenser for self-sticking mark-strips |
| (57) A dispenser is composed by supply-, transportation- (1,2) and cutting-rolls (5) which
is applied to supply self-sticking tape, to cut and then deliver self-sticking strip
to the teartape and/or packing material, at the starting point of the teartape of
in packing-foil packed articles like packages of cigarettes. The applicated packing
material can be of different types of material, as long as the self-sticking strip
can attach itself to this material. |
[0001] The invention relates to the application of self-sticking marking-strips positioned at the beginning of the tear-tape of an in packing-foil packed article like a pack op cigarettes, what by means of an in-line working machine, assembled to and driven by a packing-machine, will be realised.
[0002] Teartape will be applicated at an in packing-foil packed article like a pack of cigarettes to strip of the relevant article of it's packing-foil by the user. After the self-sticking strip has been attached to the packing foil, the u-shape knive will cut the packing foil and the tape at regular distances, by which a place of application arises, what will serve later on as a starting point when user will strip of the article from it's packing-foil.
[0003] Normally the teartape will be attached by means of an in-line placed teartape dispenser which continuously attaches the tape to the packing-foil. By this packing-method the above mentioned starting point will remain unmarked.
[0004] Another method to attache teartape to the packing-foil is to use the "cross feed-system". With this method a strip will be cut of from a roll, which is provided with a marking-line on one side, and be delivered to the packing-foil and by means of a heating machine attached to the packing-foil. This cross-feed system knows a lot of disadvantages:
- The system is only applyable to one type packingmachine
- For every length of packing-foil one needs a matchable width of the roll with the marking-line
- Quality-problems in connection with the possition of the tape and the heating during attachment.
- Limited speed
- Becomes quickly filthy
- Requires lots of maintenance and is difficult to advance
[0005] The advantage of this invention can be reached by delivering self-sticking marking-tape at the starting position by means of an in-line working machine. By application of self-sticking marking-tape the heating-element can fall into decay.
[0006] By keeping the proces of "adding the marking-tape" seperately from "the supply of the proper teartape" the last-mentioned can be supplied in-line and also continuously. If than self-sticking tape will be applicated, the heating-machine will be superfluous.
[0007] By replacement of the cross-feed system higher production-speed can be reached and the maintenance will for the biggest part fall into decay.
[0008] By using the driving gear of the packing-machine and a transportation-proportion of 1:1 between this packing-machine and the dispenser, the marking strips will automaticaly be delivered with an equal interval independent from the length of these intervals.
[0009] The invention will be illustrated on the basis of this drawings with this operation-principle:
Figure 1 is the front-view
Figure 2 is a cross-section
The mechanism operates as follows:The self-sticking marking-tape is continuously supplied by means of the roll "1" and a press-roll "2". After the driving rolls the marking tape will be pulled at the vacuum-disk by vacuum. A stationary timing-disk "4" at the back-side of the vacuum-disk "3" will appoint the position where vacuum is present.
The outline speed of the vacuum-disk "3" on which the marking strip with the not-sticking side of the tape is sucked onto, has the same speed as the one of the packing-foil.
The transportation-proportion of the vacuum-disk "3" and the supply-roll "1" appoints the transportation-length of the tape. Halfway vacuum-disk "3" a rotating knive "5", which has the same number of revolutions as the disk "3", will cut the tape. The cut tape will by means of the vacuum-power remain at the disk and be accelerated equally to the speed of the vacuum-disk "3". At the upper point the self-sticking side of the marking-strip gets in contact with the packing-foil, by which the timing-disk "4" will take care of releasing the vacuum. Herethrough the marking-strip will be taken over by the packing-foil, right at the position where the U-shape knife cuts later on a starting point.
With a transportation-proportion of approximately 1:8 the supply-roll "1" will continuously supply marking-tape to the vacuum disk "3".
1. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packingmaterial with this feature that this will be continuously
supplied, made at length and attached to the extending part of the pull-strip and/or
packing-foil.
2. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 1 with this feature that the
marking-part will be acquired by cutting of the endless strip which is supplied from
a spool.
3. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 2 with this feature that the
endless strip is on one-side self-sticking.
4. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 2 and 3 with this feature that
this strip will be supplied from a spool via two supply-rolls to a vacuum wheel.
5. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 2, 3 and 4 with this feature
that the not sticking side of the strip will be brought in contact with the vacuum-wheel.
6. operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 4 and 5 with this feature that
the stich to the vacuum-wheel is caused by little openings at the outline of the wheel,
which at regular times will be brought in contact with the vacuum.
7. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 6 with this feature that the
regular junction at the vacuum is achieved by means of a timing-disk, which achieves
the vacuum with the right openings in the vacuum wheel.
8. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 5, 6 and 7 with this feature
that the mark-strip at the vacuum-wheel will be cut at any desired length by means
of a contra cutting-knive.
9. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
packing-foil of the packing material as per conclusion 8 with this feature that the
cutting-knive is attached to a rotating disk, which turns the same number of revolutions
as the vacuum disk.
10. Operation-methode, as well as machines for applying a mark at the pull-strip and/or
