Specific embodiment

As seen in Figure 1, puncher 1 includes magnet drum 2, counter-pressure cylinders 3 and magnetically in preferred embodiments It is fastened on magnet drum 2 and is flexible pressing sheet material 4.The cutting schematically indicated is configured on pressing sheet material 4 Line 5, for being punched to along transporting direction 6a operation by the film tube 6 of puncher 1.

Obvious in as shown in schematically exaggerating in Fig. 1, film tube 6 is in axial direction folded flat and therefore exists With the wall towards pressing sheet material 4 and towards the wall of counter-pressure cylinders 3 when operation is by puncher 1.

In addition, obvious such as in Fig. 1, at least magnet drum 2 drives by electric motor 7, which preferably watches Take motor.Such as form of magnet drum 2 be angular speed revolving speed DG can by by control unit 8 for motor 7 control come Targetedly influence.

Such as from Fig. 2 in the diagram as it can be seen that can be the previously given different revolving speed in each turned position of magnet drum 2 DG1, DG2, in continuous work operation thus as every circle of magnet drum 2 rotates, angular speed DG is all between these revolving speeds Fluctuate to phase property.

Pressing sheet material 4 flexible includes at least one first area 4a, wherein, the first cutting line 5a Q in transverse direction And longitudinal direction L extends.It is especially understood to, the first cutting line 5a can also obliquely, i.e. with transverse direction Q and longitudinal direction The mode of direction L combination extends.

Addedly or as an alternative, it is configured at least one second area 4b on pressing sheet material 4 flexible, there is only edge The second cutting line 5b that transverse direction Q extends.

In the example shown, there are two second area 4b for construction on pressing sheet material, they have each other in circumference On the identical second cutting line 5b that is evenly distributed, to be beaten for manufacturing tearing for spacing having the same in film tube 6 Hole portion.

In the example shown, two first area 4a are also configured on pressing sheet material, they have each other in circle The identical first cutting line 5a being evenly distributed on week, for constructing tearing tongue piece.First cutting line 5a can be at this It is arbitrarily arranged on pressing sheet material 4, that is, is arranged between the second cutting line 5b under part.

The peripheral speed UGb of the peripheral speed UGa of first cutting line 5a and the second cutting line 5b are in the work with counter-pressure cylinders 3 With in region, or in other words when being contacted with operation by the film tube 6 of puncher 1, the substantially travelling speed with film tube 6 6a is identical.Magnet drum is thus with the first revolving speed DG1 rotation.

In contrast, except the zone of action 9, i.e., when first cutting line 5a, 5b does not touch film tube 6, first is cut Peripheral speed UGa, UGb of secant 5a, 5b can be changed.This is preferably by slowing down or accelerating to the second revolving speed magnet drum 2 DG2 is carried out.

Depending on the quantity of first cutting line 5a, 5b and position, control unit 8 is therefore by revolving speed DG in the first revolving speed It is periodically adjusted between DG1 and the second revolving speed DG2.Between the first revolving speed and the second revolving speed, revolving speed is arbitrary in principle Change curve is possible.

The circumference for passing through the zone of action 9 with the first revolving speed DG1 movement of pressing sheet material 4 is identified with hacures in Fig. 2 On section.Gone out with logos with the revolving speed DG different from the first revolving speed, for example with the second revolving speed DG2 movement and passes through active region Section on the circumference in domain.This is only used for schematic view.

Therefore adjustable, between each drill process of the first cutting line 5a and the second cutting line 5b progress Film tube 6 transported how far.Under conditions of the travelling speed 6a of film tube 6 is substantial constant, therefore obtain cutting with first Between the transverse direction that secant 5a and the second cutting line 5b are manufactured on film tube 6/longitudinal direction punching portion 10a and lateral punching portion 10b Spacing.

In the example shown, the wall towards magnet drum 2 across film tube 6 is only produced respectively with the first cutting line 5a Transverse direction/longitudinal direction punching portion the 10a for being used to tear tongue piece of 6b.In contrast, with the second cutting line 5b in the entire of film tube 6 The lateral punching portion 10b for being each passed through two walls 6b, 6c of film tube 6 is produced on width.The height Ha of first cutting line 5a It is lower than the height Hb of the second cutting line 5b in this case.

But the two of film tube 6 is had passed through it is also possible that having manufactured using the cutting line 5a with suitable height Ha Transverse direction/longitudinal direction punching the portion for being used to tear tongue piece or the like of a wall 6b, 6c.

Lateral punching portion 10b is used to draw film tube 6 section into the label cover of the still mutual company of extension, and label cover is for example by punching The suitable longitudinal tension force in the downstream of machine 1 is successively torn from film tube 6 for labelling for container etc..

Lateral punching portion 10b is preferably constituted as follows, that is, compared to the transverse direction for tearing tongue piece/longitudinal direction punching portion 10a, in the lower situation of longitudinal tension force in film tube 6 under just pull off.Laterally/longitudinal punching portion should only complete The product of labelling is just torn as when defined use, rather than is torn when film tube 6 is separated into label.

Depending on tag length to be regulated, it can be by changing revolving speed DG except the zone of action 9 come neatly Match peripheral speed UGa, UGb of cutting line 5a, 5b.For this purpose, can store corresponding periodic turn in control unit 8 Speed distribution general provisions.Then revolving speed distribution general provisions are transferred for each tag types to be manufactured with may rely on specification.

Fig. 3 is schematically shown in the top view of the pressing sheet material 4 of flattening in the affiliated region of pressing sheet material 4 The possible arrangement of the first cutting line 5a and the second cutting line 5b in 4a, 4b.

Furthermore Fig. 3 is explained beats by the way that transverse direction/longitudinal direction punching portion 10a of the change progress of revolving speed DG is mutual with lateral Hole portion 10b mutual location matches relationship.Therefore, the spacing 12b between lateral punching portion 10b targetedly with cutting line Spacing 11b between 5b is different.In this example, thus respectively in couples with the first revolving speed DG1 punching press transverse direction/longitudinal punching portion 10a and lateral punching portion 10b, and magnet drum 2 is briefly braked to the second revolving speed DG therebetween.Spacing 12b is corresponding herein In the tag length after transversely punching portion 10b separation.

Fig. 4 schematically explains first cutting line 51a, 52a and the second cutting line 51b soft in flat Possible arrangement in the affiliated first area 41a and second area 41b of the pressing sheet material 41 of property.

First cutting line 51a, 52a is preferably constructed to two walls 6b, 6c for passing through film tube 6 and punches.It is specific First cutting line 51a, 52a of pressing sheet material 41 can be configured to the punching for different width and/or length.This It is schematically indicated in Fig. 4.But in principle it is also possible that with different height Ha in other words with the difference of pressing sheet material 41 Overall thickness construct first cutting line 51a, 52a.

Therefore, the transverse direction for tilting extension in this example/longitudinal direction punching portion 101a and the use for tearing tongue piece be can produce In the transverse direction being orthogonally oriented in this example/longitudinal direction punching portion 102a of tear line.Tear line is in order in the production for completing labelling Torn on product and substantially in a transverse direction Q construct.Tear line and the area for tearing punching portion (i.e. lateral punching portion 101b) It does not essentially consist of, tear line is configured for transversely/longitudinal direction punching portion 102a gradually tearing.Tear line can be such as Also obliquely extend.

Second tear line 51b of pressing sheet material 41 is also configured to punch simultaneously across two walls 6b, 6c of film tube 6 And it is therefore configured for manufacturing lateral punching portion 101b.The transverse direction punching portion, which is used as, tears punching portion to be used for film tube 6 are separated into label.

Cutting line 51b, 51a and 52a are configured as follows, that is, so that it is generated tear punching portion with it is generated Tear line and/or tearing tongue piece in the lower situation of longitudinal tension force in film tube 6 compared to being just torn, to make tear line And/or tearing tongue piece is remained intact in separation.

As in Fig. 4 schematically as it can be seen that first cutting line 51a, 52a and the second cutting line 51b are constructed as follows, That is, making the folding seamed edge 6d of the lateral limit of film tube 6 is outer not to be perforated.Nevertheless, transverse direction punching portion 10b is in function Can on still extend on the entire width of film tube 6.On the one hand this can realize satisfactory separation, and on the other hand It prevents the damage of the film tube 6 in the film tube 6 that transmission is had openning hole in the region for folding seamed edge 6d and/or asks Topic.

Fig. 4 by be similar to Fig. 3 in a manner of explain by change revolving speed DG come carry out transverse direction/longitudinal direction punching portion 101a, The length matching of 102a and lateral punching portion 101b.Therefore, lateral punching portion is adjusted by periodically matching revolving speed DG Spacing 121b between 101b.Spacing 121b also corresponds to the tag length after transversely punching portion 101b separation herein.

And the spacing 122b between transverse direction punching portion 101b and adjacent transverse direction/longitudinal direction punching portion 102a be it is constant, this It is because the two is by transverse direction/longitudinal direction punching portion 101a connection of inclination extension and in the travelling speed for corresponding to film tube 6 By the common punching press of the two in the case where the first revolving speed DG1 of 6a.

In order to manufacture different labels and/or in order to process the film tube 6, Ke Yiti that thickness is different and/or material is different For different pressing sheet materials 4,41.Pressing sheet material 4,41 can be in first cutting line 5a, 51a, 52a and second cutting line 5b, 51b Move towards aspect, and/or in terms of the height of each cutting line 5a, 51a, 52a, 5b, 51b, and/or each pressing sheet material 4, The quantitative aspects of cutting line 5a, 51a, 52a, 5b, 51b of 41 same type, and/or in terms of the thickness of pressing sheet material 4,41 It is different.

Different pressing sheet materials 4,41 can be used as relatively inexpensive suite to provide.It can phase with low equipment cost Installation to simply and accurately realizing on magnet drum 2.For this purpose, there are multiple known in itself on magnet drum 2 Pressing sheet material 4,41 is respectively relative to magnet drum 2 and kept in anti-relative rotation and in work by magnetic area (not shown), magnetic area It is servo-actuated to friction lock in running.

Following work can be for example carried out with puncher 1.

It is preferably continuously conveyed along the film tube 6 that seamed edge 6d is folded is folded from reel with constant travelling speed 6a To puncher 1.

Magnet drum 2 drives as follows by motor 7 and control unit 8, that is, so that being present on pressing sheet material 4,41 Cutting line 5a, 51a, 52a, 5b, 51b be respectively provided with and substantially correspond to (in the zone of action 9) when being contacted with film tube 6 Peripheral speed UGa, UGb of the travelling speed 6a of film tube 6.Cutting line 5a, 51a, 52a, 5b, 51b then with film tube 6 together It advances.

Depending on the height of cutting line 5a, 51a, 52a, 5b, 51b more than pressing sheet material 4,41, herein targetedly Ground generates laterally/longitudinal punching portion 10a, 101a, 102a, these laterally/longitudinal punching portions extend only through the direction of film tube 6 The wall 6b of pressing sheet material or two wall 6b, 6c being stacked for extending through film tube 6, and/or generate lateral punching portion 10b, 101b, these lateral punching portions extend through two wall 6b, 6c being stacked of film tube 6 and herein functionally especially Extend on the entire width of film tube 6.Here, punching hole or punching have skipped over the folding seamed edge 6d of film tube 6.
