Abstract

The method involves punching out labels (6) from a label strip (8) on a paper or foil material in a roll gap between two rotating rollers. The punched out labels are drawn in against one of the rollers. Chads or punching wastes are produced during the punching out of the labels from the label strip, and are discharged separately from the punched out labels in a roller gap (18). The chads or punching wastes in the roller gap are cut through and discharged in the form of individual separate cuts from the roller gap. An independent claim is also included for a device for labeling articles, comprising two rotating rollers.

Description

The The invention relates to a method and a device for labeling of items, such as bottles or other packaging containers, according to the preamble of claims 1 or 10 and 22.

A method and an apparatus of the type mentioned for labeling of cylindrical containers, such as cans, bottles or cans with rotating labels are from the DE 20 2005 002 793 U1 known. In the known method, the label tape is cut between a rotating vacuum roller and a rotating cutting element of the device in pairs adjacent rectangular labels whose dimensions transversely to the direction of movement of the tape correspond to the width of the tape, so that no punching residues or punching waste are generated.

While it with the labeling of cylindrical containers with circulating labels is common, rectangular labels This is when labeling cylindrical containers with non-circulating labels and especially with the labeling from other packaging containers of aesthetic Reasons often undesirable. Instead There are often round labels, rectangular labels with rounded ones Corners or labels used with other shapes. These labels So far, they are usually processed in the form of loose labels, the one by one from a stack of labels removed and then with the help an adhesive glued to the items to be labeled become. However, the use of loose labels makes a number required by additional processing steps, such as the punching of the label stack in a flatbed punch and the insertion of the label stacks into a label magazine, what with relatively small quantities is uneconomical. On the other hand, especially labels with round, oval or other non-rectangular shape only with additional effort trouble-free from a label magazine remove.

outgoing This is the object of the invention, a labeling method and a labeling device of the type mentioned above To improve that even labels punched out of the label tape can be a shape other than a rectangle or transverse to the direction of movement of the label tape smaller dimensions as this possess, without the resulting fit of Puncture residues or punching waste when labeling to malfunction can lead.

These The object is achieved by the features of claims 1 and 10 solved. After that are facilities intended to be generated when punching the labels out of the tape Punched or punched waste separated from the punched Remove labels from the nip.

advantageously, are the punching or punching waste in another Direction as the labels are removed from the nip, for a clean separation of labels on the one hand and stamping residues or punching waste on the other hand cause.

A first preferred alternative provides, the punching residues or sucking punching waste against a circumference of the punching roller and remove in the course of the rotation of the punching roller from the nip. For this purpose, the punching roller preferably has at its periphery Air openings on during part of each revolution of the punching roller, namely in the direction of rotation behind the nip, through radial channels with an inside the punching roller arranged stationary vacuum chamber communicate, in which a negative pressure is maintained, around the blanks against the air openings at the mouths of Aspirate channels.

Preferably The punching residues or punching waste are already in the nip cut transversely to the direction of movement of the label tape to them on the circumference of the punching roll in the form of individual separate blanks transport away later easier from the punching roller can be sucked off and / or blown off. To cut through the punching residues or punching waste are preferred over the punching roll used protruding punching knife, the transverse to the direction of movement of the tape from the punching of the labels used label punches across the adjacent ones Side edge of the respective label tape out in the direction of a Extend the end face of the punching roller.

The Remove the punching residue or punching waste from the circumference of the Punching roll is preferably carried out at a predetermined angular distance from the nip, adding the punching residue or punching waste by means of an external suction device from the peripheral surface sucked the punching roller and at the same time in the peripheral surface the punching roller opening channels from the vacuum chamber separated and possibly with a compressed air chamber inside the punching roller get connected.

Where the labels do not extend transversely to the direction of movement of the label tape over its entire width, but are formed after punching the labels openings in a continuous punching waste tape, this punching waste strip can also be withdrawn from the nip according to a second alternative be either to wind on a take-up reel or transport by means of transport rollers to a waste container.

Further The invention is based on the object, a labeling device of the type mentioned above to improve that the punched Labels also on flexible surfaces and on surfaces glued with circumferential protruding edges can be.

These Task becomes according to another invention alternative and preferred embodiment of the invention solved by that the transfer roller on its circumference protruding elastic pads has, which are provided with the air openings. The Upholstery can be on the one hand according to the compliance deform the surfaces to be labeled something and allow it because of their supernatant also, surfaces to label, which are surrounded by a protruding edge.

About that In addition, the elastic material of the pad during punching slightly deformed and compressed in the area of the edges of the pad, so that the narrow edges of the labels resting on them the surface of the padding away towards the middle of the pad Transfer roller to be bent and the subsequent glue application remained insignificant. In this way, a gluing near the edge can be ensured with no glue on the front of the labels.

Possibly The upholstery can be bevelled or rounded Have edges to support this process.

in the Following is the invention with reference to some shown in the drawing Embodiments explained in more detail. Show it:

7 : An enlarged perspective view of a portion of the circumference of a transfer roller of the labeling device 5 ;

8th : an enlarged detail view of the section VIII in 3 ,

The illustrated labeling devices 2 serve for labeling of packaging containers 4 , for example for sticking labels 6 on rectangular ( 1 and 2 ) or round ( 3 and 4 ) Film closures of deep-drawn containers with pet food or on bottles ( 5 to 7 ), which are indicated in the drawing only schematically.

As in the 2 . 4 and 6 shown are the labels 6 Part of an elongated label tape 8th from a paper or foil material with parallel longitudinal side edges 10 , on whose one broadside surface images (not shown) of the labels 6 printed side by side. The edges 12 the illustrated labels 6 have a shape deviating from the rectangular shape and / or have transversely to the longitudinal direction of the band 8th a dimension deviating from its width. For example, it can be rectangular labels 6 with rounded corners that act without spacing next to each other on the tape 8th are arranged as in 2 or round labels 6 at a distance from each other on the tape 8th are arranged as in 4 represented, or even in pairs differently shaped labels 6 For example, square or round labels 6 , as in 6 shown on the front or back of a bottle 4 ( 5 ) and therefore also at a distance from each other on the tape 8th are arranged.

The labeling devices 2 include a supply roll 14 for the label tape 8th , a transport mechanism 16 for feeding the label tape 8th in a nip 18 between a punching roller 22 and a transfer roller 24 where the labels 6 with the help of protruding label punches 20 on the punching roller 22 from the label tape 8th punched out and then from the transfer roller 24 be transported further, a Beleimungsstation 26 for applying an adhesive to the back of the labels 6 before sticking on the objects 4 , possibly an activation station 28 for activating the adhesive when using a contact adhesive, as well as a means of transport 32 containing the items to be labeled 4 for sticking the labels 6 at the transfer roller 24 ( 3 ) or at one between the transfer roller 24 and the means of transport 32 arranged further transfer roller 30 ( 1 and 5 ) transported by.

The transport mechanism 16 includes a pair of drive rollers 34 for removing the label tape 8th from the supply roll 14 , a security camera 36 , the marks on the label tape 8th captured and the drive rollers 34 such controls that the label punching knife 20 the punching roller 22 the labels 6 in the direction of movement of the tape 8th exactly along the intended edges 12 from the tape 8th punch out, and one between the supply roll 14 and the drive rollers 34 arranged side edge control 38 holding the label tape 8th aligned transversely to the direction of movement so that the punching knife 20 in this direction also just above the edges 12 the labels 6 to come to rest.

The over a cylindrical peripheral surface of the punching roller 22 protruding label puncher 20 , a total of four in the embodiment in 1 , ten in the embodiment in 3 and eight in the embodiment in FIG 5 , each have one with the outline of the label edges 12 Matching shape, so that the labels 6 be singulated during punching and in this state of the transfer roller 24 can be transported. For this purpose, the transfer roller rotates 24 at the same peripheral speed as the punching roller 22 , wherein the peripheral speed of the feed rate of the label tape 8th equivalent.

For further transport of the labels 6 is the transfer roller 24 at its periphery with a plurality of air openings 40 ( 7 ) provided during one revolution of the transfer roller 24 in the direction of rotation behind the nip 18 over a predetermined angle of rotation through radial bores or channels with one inside the transfer roller 24 arranged stationary vacuum chamber (not shown) communicate. The vacuum chamber is connected to a vacuum pump or other vacuum source, such that over the rotation angle of about 180 degrees at the air openings 40 a negative pressure is applied, as through the roll center directed towards arrows in 1 . 3 and 5 shown. This negative pressure sucks the labels 6 against the circumference of the transfer roller 24 and holds them against these adjacent. To the labels 6 in support of gluing on the objects 4 ( 3 ) or for transfer to the further transfer roller 30 ( 1 and 5 ) easier again from the circumference of the transfer roller 24 To solve, the inner junctions of the channels move on the objects 4 or the transfer roller 30 facing side of the transfer roller 24 by a compressed air chamber connected to a compressed air source, so that at this point the air openings 40 be acted upon with compressed air, as directed by the roll circumference towards the arrows in the 1 . 3 and 5 displayed.

Where the printed broad side surface of the label tape 8th , as in 3 , in the direction of the transfer roller 24 points and the labels 6 directly from the transfer roller 24 on the objects 4 are glued, is the transfer roller 24 with protruding elastic pads 42 whose outline corresponds to the outline of the respective labels 6 corresponds, as exemplified in 7 shown. There, where the upholstery 42 on the transfer roller 24 are provided, which are communicating with the vacuum or compressed air chamber air openings 40 on the tops of the upholstery 42 arranged as well in 7 exemplified. The gluing station 26 and possibly the activation station 28 are in this case in the direction of rotation of the transfer roller 24 behind the nip 18 at a small distance from the circumference of the transfer roller 24 arranged.

If the printed broad side surface of the label tape 6 , as in 1 and 5 , in the direction of the punching roller 22 points, becomes the further transfer roller 30 needed, which the labels 6 from the transfer roller 24 on the items to be labeled 4 transferred. The transfer roller 30 in 1 and 5 has substantially the same construction as the transfer roller 24 in 3 ie it is also with overlapping cushions 42 provided, whose air openings 40 over a predetermined angle of rotation of the transfer roller 30 can be acted upon by a negative pressure or compressed air. However, the diameter of the transfer roller can be 30 larger than that of the transfer roller 24 be like in 5 shown. The gluing station 26 and possibly the activation station 28 are in this case at a small distance from the circumference of the transfer roller 30 arranged.

Through the elastic upholstery 42 on the transfer roller 24 ( 3 ) or the transfer roller 30 ( 5 ) can the labels 6 also on compliant and / or surrounded by a protruding edge surfaces of the objects 4 glued, as is often the case for example with film closures of containers with pet food, such as dog or cat food. As in 8th is also shown when punching the labels 6 in the nip 18 between the punching roller 22 and the transfer roller 24 a circumferential edge 39 the upholstery 42 from the label punches 20 something in the direction of a metallic peripheral surface 41 the transfer roller 24 pressed as the counter surface for the punching knife 20 serves. This also causes the edges of the labels 6 over the edges 39 the upholstery 42 something in the direction of the peripheral surface 41 bent so that in the subsequent gluing station ( 3 ) no lei on these narrow label edges 39 is applied. This allows edge-to-edge gluing of the labels 6 without the risk of contamination of the front sides of the labels 6 with glue.

At the gluing station 26 The adhesive can be applied to the back of the labels by rolling it up, spraying it on in any other way over the entire surface or over part of the area 6 be applied. The gluing station 26 and the activation station required if needed 28 have a known structure and should therefore not be described in detail here.

As in 1 and 5 shown opposite the gluing or activating station 26 respectively. 28 Missing labels, ie not properly on the items 4 glued labels 6 or because of the lack of objects 4 not glued labels 6 by means of a suction device 44 from the cushions 42 the transfer roller 30 be sucked off. To assist the suction can be at the air openings 40 in the top of the upholstery 42 opening channels opposite the suction device 44 be acted upon with compressed air.

All of the in 2 . 4 and 6 illustrated labels 6 is common that when replacing the labels 6 from the label tape 8th Punches or punching waste incurred. These stamping remnants can either take the form of individual separate blanks in the form of gussets 46 accept if the edges 12 adjacent labels as in the in 2 illustrated label tape 8th adjoin one another without spacing and partly with the side edges 10 of the label tape 8th coincide or may take the form of a continuous perforated punching waste band 48 accept if the edges 12 adjacent labels 6 as with the in 3 and 6 illustrated label tapes 8th at a distance from each other and from the two side edges 10 the label tapes 8th are arranged. Alternatively, the stamping scraps or punching scraps may also take the form of two separate narrow bands as the edges 12 adjacent labels 8th adjacent to each other, but at a distance from the side edges 10 of the label tape 8th are arranged (not shown).

To malfunction due to the resulting punching residues or punching waste 46 . 48 To avoid these, they are in the labeling devices shown in the drawing 2 separated from the labels 6 in another direction out of the nip 18 dissipated.

At the in 1 illustrated labeling device 2 For this purpose, not only is the scope of the transfer rollers 24 and 30 but also the scope of the punching roller 22 with air openings 40 provided during each revolution of the punching roller 22 by corresponding radial channels over a predetermined angle of rotation in the direction of rotation behind the nip 18 , in the present case about 180 degrees, with a stationary vacuum chamber inside the punching roller 22 communicate.

Unlike the transfer rollers 24 . 30 are the air openings 40 the punching roller 22 but outside of the label punches 20 surrounded areas of the roll circumference, for example, in the in 2 illustrated label tape 8th below the gusset 46 , which thereby against the circumference of the punching roller 22 be adhered to.

The vacuum chamber is with the same vacuum source as the vacuum chambers of the transfer rollers 24 . 30 connected to the punching scraps or punching scraps until reaching one above the punching roller 22 arranged suction device 50 as indicated by the arrows directed towards the roller center in 1 shown. The suction device 50 is the same as the suction device 44 connected to a suction fan or the vacuum source communicating with the vacuum chambers to the punching residues or punching waste 46 . 48 on the circumference of the punching roller 22 suck. Opposite the suction device 50 then the channels communicate with a stationary compressed air chamber inside the punching roll 22 to the punching residue or punching waste 46 . 48 for supporting the suction with the help of the outflowing compressed air from the circumference of the punching roller 22 blow off.

When processing in the 4 or 6 illustrated label tapes 8th and similar label tapes where the labels are 6 do not extend over the entire bandwidth, so that continuous perforated punching waste bands 48 are generated, the punching roller has 22 next to the punching out of the labels 6 serving label punching knives 20 additional punching knives (not shown) extending from the label punches 20 from parallel to the axis of rotation of the punching roller 22 over the side edges 10 of the label tape 8th extend out and serve that into the nip 18 incoming label tape 8th along transverse cutting lines 52 on both sides of the labels 6 perpendicular to its direction of movement in a variety of individual blanks 54 to cut up. In the 4 and 6 by dashed lines shown cutting lines 52 are preferably arranged at the narrowest points and / or equidistant from each other, but may, in addition to the illustrated cutting lines 52 include more cutting lines to the from the nip 18 emerging punching waste tape 48 continue to shred. The resulting blanks 54 can be lighter than a continuous punching waste tape 48 on the circumference of the punching roller 22 aspirate and also need after their passage through the suction device 50 less space in a downstream waste container (not shown).

Alternatively, however, can also be provided, a continuous punching waste tape 48 uncut from the nip 18 to avoid malfunctions caused by stamping residues or punching waste. The punching roller 22 does not need air openings 40 provided and be acted upon with negative pressure and the suction device 50 is dispensable, but instead is either a take-up reel 56 for winding the emerging from the nip punching waste strip 48 needed, as in 5 represented, or one behind the nip 18 in extension of the label tape 8th arranged pair of transport rollers 58 . 60 , as in 3 shown from opposite sides against that between the rollers 58 . 60 passed through punching tape 48 be pressed and of which at least one with the feed rate of the label tape 8th is driven. The transport wheels 58 . 60 may also be designed as cutting rollers to the punching waste strip 48 cut into smaller pieces, which are then alternative to the tape 48 from behind and under the pair of rollers 58 . 60 arranged waste container 62 can be included.

To the band 48 in the largest possible distance from the labels 6 on the transfer roller 24 and from the cutting knives 20 on the punching roller 22 it is the same as the label tape 8th preferably tangential to the two rolls 22 . 24 aligned.
