Abstract

The invention relates to a device for producing a strip with self-adhesive labels (12) or other materials with parts (22) placed underneath. According to the invention, the labels are detached from a first carrier strip (11) at a first removal station (13) and placed onto a second carrier strip (14). The other parts (22) are delivered intermittently on a third carrier strip (21). A second removal station (23) detaches said other parts and places them on a fourth carrier strip (24) in the desired position. Said fourth carrier strip (24) may act as the second carrier strip (14). The original carrier strip (11) may also act as the second or fourth carrier strip. The other parts (22) can be placed in any position under the labels (12) using an appropriate control system. Security elements can be used advantageously as other parts. This provides a simple means of producing a strip of security labels. The security element is transferred onto the item being labelled at the same time, i.e. during the same operation as the self-adhesive label is peeled off of the carrier strip, said security element then protecting said item. The invention also relates to a device for laterally controlling and regulating the guiding of lines and strips, especially lines of labels and their carrier strips, the edge of the line being identified by means of a line-edge control device with a sensor. The regulating process takes place by changing the direction of the control rolls over which the line is guided. According to the invention, a sliding is also provided, the line being guided in said sliding. The sliding has a straight edge which conveys a reference edge to the sensor for determining the edge of the line, and is arranged in the area of the sensor. The sliding is easy-running and floats along with the laterally guided line.

Description

Device for producing a strip with self-adhesive labels or other materials with underlaid parts and for lateral edge guidance

State of the art

The invention relates to a device for producing a strip with self-adhesive labels or other materials with underlying parts, in particular a label strip, in which removable, self-adhesive labels are applied to a carrier tape, in which other parts, such as in particular security elements, are applied under the actual label , are provided which, when the self-adhesive label is removed from the carrier tape, can be transferred together with the latter to a thing to be provided with the label, according to the type defined in the preamble of claim 1.

Self-adhesive labels are produced in a known manner in such a way that individual labels are punched out in the desired shape and size from a label material which is carried by a band-shaped carrier and is detachably bonded to the latter by punching out with a suitable punching tool. The carrier with the self-adhesive labels adhering to it is then wound up into a roll of labels after removal of the unnecessary residues of the label material, that is to say after so-called off or weeding. This is later inserted into a label dispenser, with the aid of which the detached labels are transferred to an object or article to be labeled. In practice there is a great desire for other parts to be placed under such self-adhesive labels, which can be transferred or glued to the object to be labeled with the self-adhesive label in a single work step.

A method known from EP 0 682 333 AI for producing a security label strip, in which a cover layer and electromagnetically active or activatable security elements are put together, provides that the security elements are glued to a sealing learning tape and that the security elements are attached to a dispensing edge separated from the securing element carrier tape and laminated together with the cover layer. In this publication, no device details are given from which it emerges how this method is or can be put into practice. Although general information has been given, its practical implementation is neither specified nor even hinted at.

It is an object of the present invention to provide a device with the aid of which various materials such as metal, plastics, paper, cardboard, composites or the like, which are in the form of, essentially continuously, with high speed, great precision and high flexibility during a rotational movement of punched-out labels or an endless tape lie on a carrier tape, to be transferred to a delaminated tape, either above or below.

Advantages of the invention

The device according to the invention for producing a label strip or the like with underlying parts with the characterizing features of claim 1 solves this problem. Compared to the prior art and the method for producing a security label strip described at the outset, it has the advantage of a practical machine that is built in reality and that is functional the help of which, during a rotational movement, is placed essentially continuously, with high speed, great precision and high flexibility, parts such as security elements under, in particular, self-adhesive labels. A finished label strip is then available, from which the individual labels with the other part placed below can be transferred to items to be provided in one work step.

According to the invention, this is principally achieved in that a first supply roll with associated transport device is provided, from which a first carrier tape with labels is unwound, a first removal station is provided, on which the labels are detached from this first carrier tape and after transporting advancement an area that is free of carrier tape is placed on a second carrier tape, a first winding roller with associated transport device is provided, on which the first carrier tape is wound, a second supply roll with associated transport device is provided, of which a third carrier tape is attached to it other parts, which are to be arranged under the label, is unwound, a second removal station is provided, at which the other parts are detached from this third carrier tape and, after transporting advancement over an area that is free of carrier tape, au f a fourth carrier tape is placed, a second take-up reel with associated transport device is provided, on which the third carrier tape is wound, a controlled intermittent drive is provided for the third carrier tape with the other parts thereon, with the aid of which it is localized guided, controlled advanced and intermittently driven that the other parts can be placed on the fourth carrier tape at the desired location, a third winding roll with associated transport device is provided, on which the second carrier tape can be wound, the winding speed corresponding approximately to the unwinding speed , with which the first carrier tape is unwound from the first supply roll, the fourth carrier tape provided with the attached parts can function as the second carrier tape, onto which the labels detached at the first acceptance station are placed at the desired location, precisely and in time, and thus completely or partially cover the other parts.

Advantageous further developments and improvements of the device specified in claim 1 are possible due to the features laid down in the further claims.

Thus, according to an advantageous and very expedient embodiment of the invention, the first carrier tape, from which the self-adhesive labels are removed at the first removal station, is used as the second carrier tape or the fourth carrier tape, onto which the other parts and then the labels are placed , a corresponding, suitable guidance and feeding of the first carrier tape being provided. In this embodiment of the device according to the invention, the labels are detached from the carrier tape and later put back on the same carrier tape, the other part, e.g. a security element has been applied, which is then covered exactly at the desired location by the label.

Both together, that is to say the label and another part placed underneath, are then transferred together to the thing to be labeled when the label strip is finally used, namely when labeling things. This also has the particular advantage that, for example when labeling glass bottles, when removing the label, the security element must be removed together with the label, since the adhesive effect between the security element and the label is greater than that between the label with the security element and the glass bottle. So far, this has been a particular problem in practice because the security elements are placed on the glass bottles in a separate labeling process and then the labels covering them were applied in a second separate labeling process with additional equipment. On the one hand, the exact placement is problematic on the one hand, and on the other hand, it has been found in practice that, due to the different adhesive behavior, it is hardly possible to remove both parts from the glass bottle together.

According to a further particularly expedient embodiment of the invention, the second removal station is arranged essentially perpendicular to the first removal station. This has proven to be a very beneficial arrangement for functional as well as spatial reasons.

According to a further particularly expedient embodiment of the invention, web edge controls are provided for the carrier tapes for lateral control and regulation of the tape guide. By means of these web edge controls, the carrier tapes are both guided and held individually individually on their transport route on their desired route and, on the other hand, a very expedient device is thus provided, by means of which the carrier tapes can be laterally aligned with one another. This greatly increases the flexibility and accuracy in the placement and mutual arrangement of labels and the other parts to be placed below or above them.

According to a particularly advantageous embodiment of the invention, an infinitely variable electric motor for pulling and braking the respective carrier tape, in particular via a potentiometer, is provided for each carrier tape. With this configuration, the machine is very flexible with regard to its working speed, accuracy and possible application and is adaptable to different task profiles. This configuration is further improved in a particularly expedient manner in that a central servomotor with a programmable converter for the coordinated ned driving and braking process of all transport devices is provided. Depending on the use of the machine, different motors with the possible specification of different speeds and directions can be provided for the different carrier belts. Different master motors can be used.

In a further advantageous embodiment of the invention, a detection circuit for incorrect labels is provided, preferably for each individual carrier tape provided with labels or other parts. In an improvement or as an alternative to this, a control device for detecting cracks in the carrier tape is expediently provided, preferably for each individual carrier tape provided with labels or other parts.

According to a further very advantageous embodiment of the invention, expansion shafts that can be ventilated and vented are provided automatically, on which the supply and take-up rolls are stretched. These expansion shafts, which secure the rollers on their hub in a rotationally fixed manner, can have different diameters corresponding to the occurring inner hub diameters, for example 40 mm or 3 ″ diameter. The expansion waves are also easy to replace with a suitable closure that temporarily closes the air duct. This is of decisive advantage for handling in daily practice.

A further advantageous embodiment of the invention, which is particularly important for the carrier tape advancing intermittently in another cycle, for example in the economy cycle, provides an adjustable detection circuit for the reel end of the carrier tape for the other parts, which in particular uses flashing light to detect the End of the role reports.

According to a particularly advantageous embodiment of the device according to the invention, stop and drive rollers, so-called te stop and go rollers, intended for the intermittent feed of the third carrier tape with the other parts thereon. In a particularly expedient development of this embodiment, the stopping and drive rollers are made from a special rubber. This ensures a gentle way of working that is gentle on the material and carrier tape. When using different hardness for the rubber, different hardnesses and thicknesses of the other parts can be flexibly taken into account and compensated. On the one hand, this contributes significantly to a smoother and faster machine run and thus to an increased work cycle, and on the other hand it increases the applicability of the machine. To further improve this embodiment, an advantageous development of the invention provides that the stopping and drive rollers can be replaced and / or automatically and / or pneumatically fed.

According to a further particularly advantageous embodiment of the device according to the invention, a special quick-action coupling is provided, by means of which the stop and drive rollers, the so-called stop and go rollers, are switched on or off by the drive motor. With this configuration, the working speed is further increased.

The device designed according to the invention can advantageously be used very flexibly. Thus, according to a particularly expedient embodiment, security elements can be placed under the labels as other parts, the security elements being excitable, for example, electromagnetically or acoustically or with radio frequencies. With the help of the present invention, a considerable simplification has been made for the securing of goods, which in particular consists in the fact that the security elements, already placed under the labels to be stuck on, can be delivered to the labeling points on strips in rolls in the form of rolls. There, in a single operation, things can be transferred to the thing by transferring the combined label to the thing. well secured as well as labeled. If this is already done during the manufacture or filling of the goods or items, i.e. at the source of a chain of goods, a substantial prerequisite for the so-called source tagging is created.

As already mentioned, the device designed according to the invention can advantageously be used very flexibly. Thus, according to a particularly expedient alternative embodiment, sales flags or information flags or grip loops or similar parts can be placed under the labels or stickers in such a way that parts of interest protrude under the label.

To further increase the flexibility of the device designed according to the invention, according to a further advantageous embodiment it is provided that the control is provided with a microcontroller and that different positions can be carried out with the aid of it, in particular under each or only under every 2nd, 3rd, 7th ., or a different part is placed under every 2nd, 5th, 9th label or sticker. This also makes it possible to use a different sequence of labels or stickers than the specified one.

In an advantageous embodiment of the invention, sensors are provided at different positions of the transport paths of the various carrier belts, with the aid of which the control generates corresponding position signals for the correct placement of the other parts on the fourth carrier belt, for timely operation of the stopping and drive systems. Rolling, the stop and go rolling, to advance the third carrier belt with the other parts intermittently, as well as to find, adjust and control the different speeds of the individual carrier belts.

As already emphasized several times, the device according to the invention is very flexible and versatile. According to a further advantageous embodiment, it is provided that the the other parts are placed on the fourth carrier tape in such a way that their adhesive side comes together or is laminated together with the adhesive side of the label or sticker covering them, thereby forming a removable label or label with an adhesive-free zone. This is a very popular feature in many applications in the labeling, packaging and packaging industries.

According to a particularly advantageous and expedient further development of this embodiment of the invention, it is provided that the second removal station is arranged in the immediate vicinity of the first removal station and is inclined in the transport direction of the labels detached from the first carrier web in such a way that the third carrier web passes through the second removal station loosened other parts come with their adhesive side directly on the adhesive side of the transported label, which was removed from the first carrier web immediately before by the first removal station, the two adhesive surfaces enclosing an acute angle with one another, and then both are placed together on the second carrier tape and with the other side not glued

Sometimes comes to lie directly on the second carrier tape or the fourth carrier tape.

The device according to the invention can process not only labels but also other materials to strip strips underlaid with other parts, but in an advantageous and expedient further embodiment, instead of self-adhesive labels or self-adhesive stickers, under which other parts are placed, cardboard strips or strips of plastic or others Materials or parts already punched out in the form and arranged on a carrier tape may be provided, under or above which other parts are placed with the aid of the device according to the invention. It is also possible that endless webs are processed, between which other parts are inserted and laminated. Here is, for example to think of the rotational production of laminated credit cards, chip cards or the like.

As mentioned above, the use of a web edge control is provided as a special development.

The object of the present invention relating to web edge control is to provide a device by means of which the known web edge control can also be used for diffuse edge contours, as well as for strips whose edge is not directly or only particularly difficult to recognize due to the particularly small web width. This device should be simple in construction, reliable in function and inexpensive.

Advantages of web edge control according to the invention

The device according to the invention for lateral control and regulation of the guidance of webs and strips with the characterizing features of claim 1 solves this problem. Compared to the prior art, it has the advantage of providing a device which is simple and inexpensive, by means of which the web edge control does not encounter control difficulties despite diffuse edge contours.

According to the invention, this is principally achieved in that a link guide is provided in which the web is guided, the link guide is provided with a straight edge which provides the sensor with a reference edge for web edge detection, the link guide is arranged in the region of the sensor which The slide guide is smoothly guided and floats with the laterally controlled track.

Advantageous further developments and improvements of the device specified in claim 1 are possible due to the features laid down in the further claims. Thus, according to an advantageous and very expedient embodiment of the invention, it is provided that the web rests with its one lateral edge against a first lateral stop of the link guide and with its opposite lateral edge rests against a second lateral stop that is distant according to the web width, with little play between the track and the side stops is provided. This play can be up to approx. 2/10 mm, for example. In an advantageous development, the two lateral stops can be adjusted relative to one another in accordance with the web width. In a particularly expedient embodiment, the link guide has a base part and a cover part covering it or the web lying on it.

According to a further very advantageous embodiment of the invention, the link guide is mounted on rollers, and the rollers slide on a guide which is arranged in front of the sensor transversely to the transport direction of the web and seen in the transport direction. This ensures that the slotted guide is safe and very easy to walk along or swim along with the laterally controlled track. In a further expedient embodiment of the invention, the link guide consists of a lightweight material, in particular aluminum.

In a preferred embodiment, the link guide has a web guide length in the transport direction of the web which corresponds at least to the length between two projecting areas with a larger web width. This ensures reliable guidance of webs with diffuse edges.

According to a special, very advantageous further development of

According to the invention, at least one further link guide is provided next to the first link guide and is firmly connected to it, so that at least one further web is transported next to the first and in the same way remaining distance from the first of the common reference edge is laterally adjustable.

The arrangement according to the invention is used in a very advantageous manner for the control of the web edge of webs which have diffuse, corrugated or edges provided with projections and recesses. According to an alternative use which avoids other problems of edge detection, the link guide according to the invention is used in a corresponding embodiment for controlling the web edge of one or a large number of particularly narrow strips, in particular metal strips such as security strips for banknotes.

Description of the execution and application examples

1 shows a three-dimensional schematic representation of a first exemplary embodiment of the device according to the invention for producing a label strip. The term label is used throughout the description below. However, this term label should not only be understood to mean the actual label, but also things such as stickers or the like. So these things can be printed or unprinted. They can consist of various materials, such as in particular paper, cardboard strips or strips made of plastic or other materials. You can parts that have already been punched out and weed and arranged on a carrier tape or also strip-shaped parts. The possible variations are very diverse. An essential feature of the labels is that they are self-adhesive and are applied to a carrier tape before they are used for their actual purpose, the labeling of things or goods or the transfer to a thing.

In the device designed according to the invention, a first supply roll 10 with associated transport device is provided, from which a first carrier tape 11 with labels 12 is unwound thereon. A first removal station 13 is provided, at which the labels 12 are detached from this first carrier tape 11 and, after transport or advancement, are placed on a second carrier tape 14 over an area that is free of carrier tape. A first winding roller 15 with associated transport device is provided, on which the first carrier tape 11 is wound. Furthermore, a second supply roll 20 with associated transport device is provided, from which a third carrier tape 21 with other parts 22 applied thereon, which are to be arranged under the label 12, is unwound. At a second provided removal station 23, the other parts 22 are detached from this third carrier tape 21 and, after being transported or pushed forward, placed on a fourth carrier tape 24 over an area that is free of carrier tape. A second winding roller 25 with associated transport device is provided, on which the third carrier tape 21 is wound. There is a controlled intermittent drive for the third carrier belt 21 with the other parts 22 thereon, with the aid of which it is guided locally, controlled, and intermittently driven in such a way that the other parts 22 are placed on the fourth carrier belt 24 at the desired location. Furthermore, a third take-up roll 15 with associated transport device is provided, on which the second carrier tape 14 can be taken up, the take-up speed roughly corresponding to the take-up speed. with which the first carrier tape 11 is unwound from the first supply roll 10. The fourth carrier tape 24 provided with the attached other parts 22 can function as the second carrier tape 14, onto which the labels 12 detached at the first removal station 13 are placed at the desired location precisely and in time and thus completely or partially cover the other parts 12 .

In the embodiment shown in FIG. 1, no separate fourth carrier tape 24 is provided. Furthermore, no separate second carrier tape 14 is provided in the exemplary embodiment shown. Rather, in a very practical embodiment, the second carrier tape 14, onto which the other parts 22 are placed first in the removal station 23 and then the labels 12, is the first carrier tape 11, from which the self-adhesive labels 12 are removed at the first removal station 13. used. A corresponding, suitable guiding and feeding of the first carrier tape 11 is provided. In the exemplary embodiment shown, this leads again from the supply roll 10 via the first removal station 13 and by means of correspondingly arranged deflection rollers 16 around the second removal station 23 except for one free of carrier tape

Back to the first take-off station 13 and from there, referred to as carrier tape 14, to the take-up roll 15.

Depending on requirements, up to four carrier tapes can thus be used in the device according to the invention. The first carrier tape 11 carries the labels 12 to the take-off station 13 and is then wound up on a separate winding roll and can be disposed of. The second carrier tape 14 takes over the detached labels 12 at the first removal station 13. It is fed from a supply roll (not shown in FIG. 1) and wound up on a take-up roll, the take-up roll designated 15 in FIG. The third carrier tape 21 is provided with the other parts 22, is unwound from the supply roll 20, leads the other parts 22 to the second removal station 23 and is then empty on the take-up roll 25. wraps and can be disposed of. The fourth carrier tape 24 can be fed from a separate supply roll, not shown in FIG. 1. It takes over the other parts 22 detached at the second removal station 23 and brings them together with the underside of the labels 12 on the second carrier tape 14. The use of a separate fourth carrier tape 24 is certainly advantageous if the other parts 22 and the labels 12 are also to be covered by a layer from below. This can be the case, for example, in the production of laminates such as credit cards or the like. If the second carrier band 14 is used as the fourth carrier band 24, and for this purpose is guided past the second removal station 23 to take over the other parts 22, then the separate fourth carrier band or the second carrier band 14 acts as the fourth carrier band 24. The use of such a separate carrier tape 14 = 24 by the device according to the invention simplifies it. It also offers the advantage that a special carrier tape with desired properties can be provided for receiving the finished labels 12 with underlying parts 22. In the case as shown in the exemplary embodiment of FIG. 1, the carrier tape 11 is used again for receiving the finished labels 12 with underlying parts, and thus serves both as a second carrier tape 14 and as a carrier tape 24. This means that after the other has been removed Parts 22 of the third carrier tape 21 only to be disposed of. As can be seen from this illustration, the invention provides a multitude of possibilities.

As shown in FIGS. 1 and 2, the second removal station 23 is arranged essentially perpendicular to the first removal station 13. This corresponds to the essential directions of transport of the first carrier tape 11 and third carrier tape 21 during the feeding of the labels 12 or other parts 22 in the area immediately before the respective detachment. As shown in Fig. 1, the carrier tapes 11 and 21 are each provided with a web edge control 17 and 27, respectively. The lateral position of the carrier tapes is thus determined individually and in relation to one another and the tape guide is adjusted to the set position during the run. For each carrier belt 11 or 21 there is an infinitely variable electric motor for pulling and braking the respective carrier belt, in particular via a potentiometer. These motors are not shown in the figures. A central servo motor with a programmable converter for the coordinated drive and braking process of all transport devices is also provided, also not shown in the figures. This allows a very flexible design of drive profiles, which means that a wide variety of tasks can be mastered. Depending on the use of the machine, different motors with the possible specification of different speeds and directions can be provided for the different carrier belts. Different master motors can be used to drive at different speeds.

In a further embodiment, which is not shown in the figures, the device designed according to the invention contains a detection circuit for incorrect labels, preferably for each individual carrier tape 11 or 21 provided with labels 12 or other parts 22, and a control device for detecting cracks in the Carrier tape, preferably for each individual carrier tape 11 or 21 provided with labels 12 or other parts 22. To complete the ease of use of the machine, an adjustable detection circuit for the roll end of the carrier tape 21 is provided for the other parts 22, which in particular uses flashing light to detect the device reports.

The first supply roll 10 and first or third take-up roll 15 for the carrier tape 11 shown in FIG. 1 are applied to expansion shafts 18. In the same way, the supply roll 20 and second Winding roll 25 applied to expansion shafts 28. These expansion shafts 18 and 28 can be automatically aerated and vented, ie if the hubs of the supply rollers 10 and 20 or the hubs of the winding rollers 15 and 25 are pushed onto the expansion shafts 18 and 28 when the reel is changed, this expands when compressed air is supplied for clamping the hubs. Before the rollers are removed from the expansion shafts 18 and 28, they are vented, the diameter shrinks and the hubs can be removed. The expansion shafts can have different diameters, for example 40 mm or 3 ″ (3 inches or 3 inches), depending on the hub diameter usually used, and can be easily replaced. The air supply is automatically blocked when it is removed and opened again when it is put on successfully. Bayonet locks can be used to easily change the expansion waves of different sizes.

For the intermittent feed of the carrier tape 21 with the other parts 22 thereon, that is to say the third carrier tape, stop and drive rollers, so-called stop and go rollers, are provided. In the illustration of the exemplary embodiment shown in FIG. 1, a roller 29 is shown, which is arranged in front of the second removal station 23, seen in the transport path. the associated other roller 29 is not recognizable. In the exemplary embodiment shown, supply roll 20 and take-up roll 25 for the third carrier tape 21 are arranged perpendicular to the supply roll 10 and winding roll 15 for the first carrier tape 11. The carrier tape 21 penetrates a carrier wall 30, of which a large part of the transport devices is held, and is deflected via 45 ° deflecting rollers 26 into the alignment suitable for the carrier tapes 11, 14, 24 and is guided back to the winding roller 25. It is clear that it is possible to arrange all the supply and take-up rolls in a single plane.

The other parts 22 to be placed under the labels 12 can be different parts which have different strengths and have properties. This is also reflected in the running behavior during operation. In order to ensure the best possible intermittent feed performance, according to a further expedient embodiment of the invention, the stopping and drive rollers 29 are made from a special rubber. Furthermore, the stop and drive rollers 29 can be exchangeable and / or automatically and / or pneumatically adjustable. Furthermore, a special quick-action coupling is provided, which is not shown in the figures, by means of which the stopping and drive rollers 29 are switched on or off by the drive motor. This ensures a particularly rapid sequence of the intermittent feeds of the third carrier belt 21 with the other parts 22 thereon.

FIG. 2 schematically shows a simplified representation of the first acceptance station 13 and the second acceptance station 23 and their assignment and their functions according to the present invention. The removal stations 13 and 23 essentially consist of a wedge-shaped guide part 130 or 230 with an acute-angled deflection edge 131 or 231 at the tip. This can also be called the dispensing edge. At the take-off station 13, the first carrier tape 11 with the labels 12 thereon is transported in the direction of the arrow 100 onto the deflection edge 131 and then, after the labels 12 have been detached, removed in the direction of the arrow 101. In a comparable manner, the third carrier tape 21 with the other parts 22 arranged tightly thereon is transported in the direction of the arrow 200 onto the deflection edge 231 and is then transported away in the direction of the arrow 201 after the other part 22 has been detached. The movement of the carrier belt 11 takes place continuously, while the movement of the carrier belt 21 takes place intermittently in steps which correspond approximately to the length of the other parts. The pause in motion determines the distance between the other parts 22 transferred to the carrier tape 24, 14. The fourth carrier tape 24 with the other individual part 22 on top of it runs somewhat perpendicularly to the plane of the motion path according to the arrows 100 and 140, respectively, in which the first carrier tape 11 up to the deflecting edge 131 and then the second or fourth carrier tape 14 or 24 moved to the right of the upper deflection roller 16. The right label 12 already covers another part 22, while the middle label 12 is still above the area free of the carrier tape and the next other part 12 on the carrier tape 24 is still in front of the upper deflection roller 16. The area free of carrier tape at the first removal station 13 is between the deflecting edge 131 and the upper deflecting roller 16. The area free of carrier tape at the second removal station 23 is between the deflection edge 231 and the lower deflection roller 16. In any case, this area is dimensioned shorter than it corresponds to the length of the labels 12 or other parts 22 spanning them in the transport direction 100 or 200.

With the device designed according to the invention can than others

Parts 22 security elements are placed under the labels 12, the security elements being electromagnetically or acoustically or with radio frequencies excitable. As other parts 22, sales flags or information flags or grip loops or similar parts can also be placed under the labels 12 in such a way that parts of interest protrude under the label 12. In order to be able to control this in an advantageous manner, the control is provided with a microcontroller in an embodiment of the invention. With its help, different placements can be carried out. In particular, a different part 22 can be placed under each or only under every 2nd, 3rd, 7th or under every 2nd, 5th, 9th label Control another advantageous sequence of labels or stickers can be selected.

A first application example for the device according to the invention is shown in FIG. 3. In the illustrated finished label strip 300, a different part 22 is placed under every second label 12. In the further application example of a finished label strip 40 shown in FIG. 4, there is 12 under each label another part 22 placed. The other parts 22 shown in these two application examples are completely covered by the labels 12 arranged above them.

5 schematically shows a third application example for a finished label strip 50, in which a different part 22 is placed under each label 12, of which a part 522 looks out laterally under the label, for example a handle loop. Instead of a grip loop, the protruding parts 522 can also be sales or information flags.

6 schematically shows a fourth application example for a finished label strip 60, in which under each label 12 a different part in the form of a continuous strip 612, an endless tape, for example a magnetic tape for use in special cash registers and parking garages, is placed. Instead of the magnetic tape or the strip 612, a metal strip in the form of a string, a thread of a rope or a thin thin film can also be used. It is possible to apply this metal tape endlessly or in sections. For example, it can be fed endlessly on the third carrier tape 21, cut into individual sections by cutting, and these cut parts can be placed intermittently under the labels 12. Another variant is to make the individual section of the metal thread only so long that no end looks out from under the finished label 12 and could possibly be pulled out. Such a section can be arranged transversely to or in the longitudinal direction of the label strip 60.

In the machine designed according to the invention, sensors are provided at different positions of the transport paths of the various carrier belts 11, 14, 21 and 24, with the aid of which the control generates corresponding position signals for the correct placement of the other parts 22 on the fourth carrier belt 24 or 14 or 11, for timely operation of the stop and drive rollers 29, the so-called stop and go rollers, in order to advance the third carrier belt 21 with the other parts 22 intermittently, and to find, adjust and regulate the different speeds of the individual carrier belts. These sensors, like the control system, are not shown in detail in the figures.

According to a second very advantageous exemplary embodiment, which is shown schematically in FIG. 7 and the enlarged detailed illustration according to FIG. 8, the invention can be used in a simple manner to produce a strip with self-adhesive labels or with self-adhesive stickers which have an adhesive-free zone. For this purpose, according to this embodiment, the other parts 22 to be placed are placed on the fourth carrier tape 24 in such a way that their adhesive side 722 comes together or is laminated together with the adhesive side 122 of the label 12 covering them, whereby a peelable label 127 with a non-adhesive one Zone 128 is formed.

In order to produce a label 127 with an adhesive-free zone 128, the second removal station 73 is designed somewhat differently than the removal station 23 shown in FIG. 1. This removal station 73 is arranged in the immediate vicinity of the first removal station 13 and in the transport direction 100 is that of the first carrier web 11 detached labels 12 are inclined so that the other parts detached from the third carrier web 21 by the second removal station 73 with their adhesive side 722 directly onto the adhesive side 122 of the label 12 transported above them and detached from the first carrier web 11 immediately before that by the first removal station 13 lie, the two adhesive surfaces 122 and 722 enclosing an acute angle with one another, and then both are placed and pressed together onto the second carrier tape 14, the side 128 of the other part 22 not provided with adhesive directly on the second carrier tape 14 or the fourth carrier ba nd 24 comes to rest. In the exemplary embodiment shown, the feed directions 100 of the labels 12 form and 700 of the other parts form an acute angle with one another at 90 °.

It also seems possible that when the other part 22 detached from the third carrier tape 21 is transferred to the fourth carrier tape 24, it takes over and transports it with a slightly adhesive surface until it comes together with the adhesive surface 722 with the adhesive surface 127 and is more firmly glued there. The tack-free zone 128 must then possibly be detachable from the fourth carrier tape 24.

FIG. 9 schematically shows a third essential embodiment of the device according to the invention with the first removal station 13 and the removal and supply of the first carrier tape 11 and the second carrier tape 14, this embodiment for converting the labels 12 from the old 11 to one new 14 or offset on the old carrier tape 11 is used. In this embodiment or application of the device according to the invention, which is shown schematically in FIG. 1, the second removal station is not required for this application or application. The intermittent feed of the third carrier belt 21 does not take place.

FIG. 10 schematically shows an application example for a label strip 110, in which each label 12, by means of the embodiment or mode of operation of the device according to the invention shown schematically in FIG. 9, of the first carrier tape 11 from its original position indicated by dashed lines 12 ′ is loosened and offset in the lateral direction as well as in the longitudinal direction again on the same carrier tape 11.

FIG. 11 schematically shows a second application example for a label strip 111, in which each original label 12 produced butt-to-butt is detached from the first carrier tape 11 by means of the embodiment or mode of operation of the device according to the invention shown schematically in FIG. 9 and offset again in the longitudinal direction the same carrier tape 11 or a second carrier tape 14 is placed again with an increased distance between the labels 12. In the upper part of FIG. 11, the original label strip 1 with the labels 12 arranged abutting one another is shown, and in the lower part of FIG. 11 the label strip 111 produced with the separated labels 12 is shown. The distance between the individual labels can be up to 0.5 mm small and of course larger.

Instead of labels, under which other parts are placed, cardboard strips or strips of plastic or other materials can also be processed in the present invention. It is also possible to use parts made of these materials, which have already been punched out in the form and arranged on a carrier tape, and under which other parts can be placed with the aid of the device. The possible applications are very diverse.

Advantageously, the invention allows the simple production of strips or endless tapes with self-adhesive labels, stickers or the like applied to them, under or on which other parts are placed, which is to be transferred with the self-adhesive label to the item to be labeled . Other advantageous configurations and applications are possible and have been shown in part in the description above.

A device for the lateral control and regulation of the guidance of webs and tapes is described below, which is particularly advantageous to use in the context of the invention with regard to the production of strips with labels and has been designed accordingly in accordance with the invention.

This invention is based on a device for lateral control and regulation of the guidance of webs and tapes, in particular label webs and their carrier tapes, the edge of the web being recognized by a web edge control by means of a sensor, and the control intervention takes place via change of direction of control rollers over which the web is guided, in accordance with the type defined in the preamble of claim 22.

In a known web edge control, such as that offered by Erhardt + Leimer, D-86136 Augsburg, under the designation of the rotating frame DR 21, the side of the web is controlled and regulated to detect the edge of the web by means of a sensor and to carry out the control intervention by changing the direction of control rollers over which the web is guided. The regulating rollers are arranged on a rotating frame which is controlled by a motor in accordance with the detected deviations in the edge. In this known path control, the edge is read directly and immediately by the sensor, in particular an optical sensor. In the case of webs and tapes which have diffuse, wavy or provided with projections and recesses, this known web edge control comes into difficulties particularly when the irregularities of the edge contour have a small repeat, i.e. the change in the edge contour occurs very shortly after one another. As a result, the web edge control can get completely out of step.

Self-adhesive labels are produced in a known manner in such a way that individual labels are punched out in the desired shape and size from a label material which is carried by a band-shaped carrier and is detachably bonded to the latter by punching out with a suitable punching tool. The carrier with the self-adhesive labels adhering to it is then wound up into a roll of labels after removal of the unnecessary residues of the label material, that is to say after so-called off or weeding. This is later inserted into a label dispenser, with the aid of which the detached labels are transferred to an object or article to be labeled. In practice there is a great desire for other parts to be placed under such self-adhesive labels. those that can be transferred or glued to the item to be labeled with the self-adhesive label in a single step. This can be, for example, security labels made from a security label strip which is provided with a diffuse edge contour and is to be merged with the cover sheet in the correct position.

The invention is explained in more detail in the following description with reference to exemplary embodiments of the device according to the invention shown in the drawing in FIGS. 12-13.

12, the invention is shown in perspective in connection with a known web edge control. The web edge control contains a rotating frame 1 'on which two regulating rollers 2' and 3 'are mounted. A web 4 'is guided in the direction of arrow 5' over the regulating rollers 2 'and 3', deflected on them and pulled by drive rollers, not shown. Below the regulating roller 2 ', in the middle and perpendicular to the regulating roller 2', there is a pivot point (not shown) for the rotating frame 1 ', about which it is thus rotated transversely to the transport direction. As a result, in particular the part of the web 4 'which rests on the regulating roller 3' is deflected transversely to the transport direction 5 'and shifted for lateral control and regulation. A sensor 7 'is provided to determine the position of the edge 6' of the web 4 '. This preferably optical sensor 7 'is optionally adjustable transversely to the direction of transport 5' on a rail 8 'running across the width of the web 4', which in turn is attached to the rotating frame 1 '. As a result, the sensor 7 'can be laterally adjusted to the desired position of the edge 6'. How the sensor 7 'cooperates with its signals, the drive of the rotating frame for the lateral adjustment of the track 4', and other assemblies is not shown and executed here since it is not the subject of the invention. It should also be noted that the web labeled 4 'with its edge 6' lying under the sensor 7 'and the edge 6''lying opposite it, represents the largest possible width of such a web, which can be operated by the web edge control shown. For reasons of better illustration with regard to the invention, this web 4 'is shown in FIG. 1. The associated edges 6 'and 6''are straight edges.

1 schematically shows a link guide 20 'designed according to the invention, which can be moved with smooth-running rollers 21' and 22 'on the rail 8' fastened to the rotating frame 1 'transversely to the transport direction 5', as indicated by the double arrow. The link guide 20 'can also be guided transversely to the transport direction 5' on a completely separate rail which is attached to the rotating frame 1 '. A track 41 'is guided in the link guide 20', the edges 410 'of which have projecting parts 411' with a greater width and recessed parts 412 'with a smaller width. This type of edge contour can generally be described as diffuse or more precisely as a stepped wave edge. This track 41 'is inserted into the link guide 20' in such a way that it is pulled through the opening formed by the link guide 20 'at the top and bottom and at the edges 410' with only little play. As a result, when the web 41 'is laterally displaced, the link guide 20' is also moved laterally with it. One can say that the slide guide '20' swims with the track 41 ', i.e. whose lateral movements are compulsory. The link guide 20 'has a straight edge 23' which provides the sensor 7 'with a reference edge. Instead of the diffuse edge 410 'of the web 41' with the protruding and recessed parts 411 'and 412', the sensor 7 'scans the straight edge 23' of the link guide 20 'which serves as a reference edge. This reference edge follows the movement of the web 41 'due to the forced movement of the link guide 20', and can therefore be used for lateral control and guidance of the web 41 '.

With reference to FIGS. 13 and 14, the structure of the link guide is shown schematically in front view and top view. The Rollers 21 'and 22' are attached to a bracket 24 'to which a holding frame 25' with a base part 26 'is attached. A recess 27 'is machined into the base part 26', in which on the one hand the web 41 'and on the other hand a part 30' which is adjustable transversely to the transport direction lies within the link guide 20 ', corresponding to the double arrow in FIG. 12. Both the track 41 'and the adjustable part 30' are covered with respect to the recess 27 'by a cover 28' which is fastened, for example, to the base part 26 'and the holding frame 25' with four screws 280 '. The web 4 'with its projecting parts 411' lies on the right in FIG. 12 on a first fixed lateral stop 29 ', on the left in FIG. 12 on a second lateral stop 31' which is adjustable according to the adjustability of the part 30 ' , with its underside in the recess 27 'of the base part 26' and is covered and held on the upper side by the cover 28 '. The space formed between these delimiting parts 29 ', 27', 31 'and 28' is dimensioned such that the web 41 'can slide well on the one hand without much frictional loss and on the other hand nevertheless forms a sufficiently dimensioned lateral restraint for the link guide 20'. For example, the lateral play can each be approximately 0.2 mm and the height play approximately 0.5 mm.

As already stated above, the adjustable part 30 'forms a laterally adjustable stop 31' which can be adjusted from the maximum web width, as shown in FIGS. 13 and 14, to a smaller web width towards the fixed lateral stop 29 '. For this purpose, two elongated holes 281 'are provided in the cover 28'. Locking screws 328 'are guided in these elongated holes 281'. These locking screws 328 'are connected to the adjustable part 30', hold it to the cover 28 ', can be displaced with it transversely to the transport direction 5' and hold it in the new position after tightening. Thus, an adjustable side stop 31 'is formed within the link guide 20' in a simple manner. The link guide 20 'is made of a lightweight material, in particular aluminum, in order to support the easy movement with the lateral movement of the web guided in it with a low weight.

According to a further exemplary embodiment of the invention, a plurality of webs, even with differently shaped diffuse edge contours, can be transported next to one another and guided in an aligned manner. A second path 42 'is shown in dashed lines in FIG. 12 parallel to path 41'. This web 42 'has corrugated edges 420' with protruding bellies 421 'and recessed cuts 422'. A second link guide 202 'is provided for this track 42', which is indicated by dashed lines in FIG. 12. This second link guide 202 'is mechanically connected to the first link guide 20' by means not shown. For both webs 41 'and 42' then running side by side, the straight edge 23 'of the first link guide 20' located at the sensor 7 'serves as a reference edge. In this way, two, possibly also three or more webs aligned laterally parallel to one another can be controlled and regulated in this way.

The backdrop guide according to the invention can also be designed in a further embodiment such that one or preferably a plurality of very narrow strips, such as in particular only one mm or a few mm wide metal strips, which are incorporated for example as security strips in banknotes and in which the direct detection of the straight edge because of the small web width makes considerable difficulties in edge detection by the sensor, is or are guided in the link guide in one or a plurality of passages.

Advantageously, the backdrop guide designed in accordance with the invention creates an inexpensive part which, in all conventional web edge controls, avoids the flutter problem during processing. of webs with diffuse edges in a simple, reliable and inexpensive way. Furthermore, the invention creates the possibility of guiding one or a plurality of particularly narrow strips next to one another and laterally controlling them by means of the common reference edge.
