Description

The present invention relates to a labeling machine with a labeling device, which has a supply device for supplying a carrier strip, which is provided with detachable labels, and a transfer device for transferring the labels from the carrier strip to an object to be labeled. Furthermore, the invention relates to a method for labeling articles such as goods or packaging, in which at least one object to be labeled is provided, a carrier strip, which is provided with removable labels, is fed in a transport direction of a transfer device and on the at least one object to be labeled in the transfer device detached labels from the carrier strip, whereby a liberated from labels (completely or partially freed) carrier strip portion is obtained.

Such a labeling and a corresponding method of the type mentioned is from the DE 10 2007 034 698 A1 known. Such a device has one or more conveyor sections for the transport of the articles to be labeled, for example a product or packaging. Further, a transfer device is provided, are glued in the individual labels on the object to be labeled. The labels can according to an embodiment of the device on a carrier strip, also called carrier paper supplied from which they are replaced in the transfer facility. According to a described alternative, carrier paper-free labels can be applied in the said device.

The problem with a labeling machine of the former type, in which labels are supplied via a carrier strip, is the collection of the label strip carrier strip section, ie the part of the carrier strip which is transported out of the transfer device after the labeling process, and the removal of the collected material. This carrier strip portion must be collected in containers, which containers must be regularly taught or replaced when they are full. A labeling machine according to the preamble of claim 1 is in WO 2012/097906 disclosed.

It is therefore an object of the present invention to further develop a labeling machine and a corresponding method for labeling objects of the type mentioned in that with relatively little technical effort and with the greatest possible ease of use removal of the liberated from labels carrier strip portion is made possible. This object is achieved according to the invention by a labeling machine according to claim 1, which further comprises a take-up device for winding a liberated from labels (ie completely or partially exempted) portion of the carrier strip, comprising at least one guide device with a guide element to which the carrier strip portion in a transport direction is run along, and a winding device, the at least one guide element is connected downstream and has the fixing means on which a loose end portion of the carrier strip portion is fixable, wherein the fixing means are arranged on a rotatable about a rotation axis spool core and follow a rotational movement of the spool core.

By providing a take-up device, first of all, the label strip (completely or partially) released from the carrier strip section can be collected by simple means. Preferably, this can even be done automatically. Due to the rotatable coil core of the take-up device, the carrier strip section is wound into a roll, referred to below as the carrier strip roll, which forms a particularly space-saving possibility of receiving carrier strip material, since unused gaps between individual sections of the collected carrier strip material can be avoided by the winding and a correspondingly high Packing density can be achieved. The recording of the carrier strip portion after labeling by means of a winding device or by means of a rotatable bobbin also represents a particularly simple method to collect strip material and in particular to pack as tightly as possible. Yet another advantage is that pins are arranged as fixing means on or on the rotatable spool core, as will be described in more detail below, whereby a loose end portion of the liberated from labels carrier strip portion - meaning in the transport direction front end of the carrier strip or Carrier strip section - can be fixed to the spool core at the beginning of the winding process, which turn the start of the winding particularly simple.

As used, the loose end section means the part or the end of the carrier strip section which points away from the transfer device in the direction of transport or points towards the takeup device. The loose end portion is either the production-related front or outer portion of a labeled carrier strip after the labels have been peeled off, or an end portion formed by severing the carrier strip portion, for example, after the carrier strip roll in the take-up by the Winding has a certain diameter or a certain weight received, which makes the removal of the roll from the winder required.

In the aforementioned guide element, on which the carrier strip section is guided before it is detected by the takeup device, it is, for example, a deflection element such as a deflection roller, deflection edge or the like, in the simplest case only around the end of a support surface or rail or like. In other words, the surface of the guide element forms an optionally rounded edge, pointing away from the transfer device, on which the carrier strip section is guided along and, if necessary, can be deflected. Depending on the arrangement of the spool core relative to the guide element, however, a deflection of the carrier strip portion is not always necessary; Rather, it is also conceivable that the carrier strip section from the guide element straight, that is in particular horizontal direction, to the rotatable spool core, which is in the case at the same height as the guide element, is continued. For technical reasons and / or space reasons, however, it may be desirable if the spool core or the axis of rotation of the spool core lies vertically below the guide element in a horizontal plane, in which case the guide element has a deflection function. The terms vertical and horizontal refer to the direction of gravity, that is vertical means in the direction of gravity, horizontally means transverse to it.

If it is mentioned that one device is connected downstream of another device, this is always based on the transport direction of the carrier strip section. In other words, if it is said that the winding device is connected downstream of the guide element, this means that the carrier strip section, when it moves as intended in the transport direction, first reaches the guide element and then the take-up device.

According to one embodiment of the labeling machine according to the invention, the take-up device further comprises a blower device with at least one air outlet opening, that is, an opening which is suitable for allowing air to flow out. The latter can be designed in particular as a blowing nozzle, which has the advantage that the exiting blow jet or air flow is bundled and has a correspondingly higher pressure. In particular, the air outlet opening is oriented such that an air flow exiting therefrom separates the carrier strip section after this has passed the guide element, directs in the direction of the bobbin. The air outlet opening is thus arranged in particular so that the part of the carrier strip section, which has already passed the guide element, can be pressed by the air flow in the direction of the spool core. In other words, the air outlet opening is directed to a space area, which the carrier strip section inevitably passes through due to gravity, after it has passed the guide element. In particular, the air outlet opening is aligned in the direction of an imaginary straight line which extends through the axis of rotation of the spool core and bears tangentially against the surface of the guide element. By said surface is meant the location of the guide member at which the carrier strip portion contacts the guide member during the winding operation.

Such a blower device has the advantage that the loose end portion of the carrier strip portion can be moved by means of the air flow before the winding operation in the area of action or rotation of the fixing means, thereby allowing the end portion of the fixing means is automatically detected and clamped. By the said range of action or rotation range of the fixing means is thus meant the area which is enclosed by the outside of the fixing means during a rotation of the coil core.

According to a further embodiment of the labeling machine according to the invention, the winding device further comprises a separating device with a separating element, in particular with one or more knives or blades, with one or a plurality of saw blades, with one or more needles (meaning spiked pins), with a laser cutting head or with one or more rotatable cutting discs, wherein the separating element is movable to a position in which a severing of the carrier strip portion can take place. Such severing is necessary when the carrier strip roll has reached a certain diameter or weight which makes it necessary to remove the roll from the spool core. Subsequently, a rewinding process can be started. Thus, the separating element can be brought into a position which traverses the carrier strip section either in the form of the outer layer of the carrier strip roll or in the form of a section which has not yet been wound onto the carrier strip roll. The separating element thus cuts through the carrier strip section, as a result of which the carrier strip roll is separated from the remaining carrier strip section and can be removed from the spool core.

In principle, there are various possibilities for forming the separating device and the separating element. As mentioned, the separating element can be a single separating element (eg a single knife, a saw blade, a single needle, etc.) or a two-part separating element (eg in the form of several knives, saw blades, needles, etc.). Especially in the case where the separating element is intended to sever the outer layer of the carrier strip roll, the separating element, for example a saw blade, may be spring-mounted. This has the advantage that when cutting a certain bearing force of the separating element is not exceeded on the surface to be cut, which ensures that only the upper layer of the Carrier strip role is severed and underlying layers, at least as far as possible, remain intact. In this way, the carrier strip roll can be easily disposed of after cutting as a coherent whole. The severing does not necessarily have to take place on the surface of the roll, but can also take place in the region between the roll and the labeling device and in particular in the region between the roll and the guide device, preferably between the roll and the guide element. In this area, the carrier strip portion to be cut is under tension by the tensile force generated by the driven bobbin, which makes cutting particularly easy; In particular, the carrier strip section only has to be partially cut or torn by the separating element in order then to tear through on its own. A perforation by the described needle or the described plurality of needles as a separating element is sufficient to cause a tearing of the carrier strip portion in the desired area. As already mentioned, a laser cutting head can also be provided, that is to say a component producing a laser beam, in which case the laser beam causes the cut or the partial cut by heating the carrier strip section.

The stroke carried out by the separating element between the position in which the separating element contacts the surface to be cut and the rest position spaced therefrom is preferably a maximum of a few millimeters. In particular, the stroke is in a range of less than 5 mm, preferably less than 3 mm, and more preferably in a range of 0.1 to 2 mm.

In order to enable a severing, the separating element performs a movement which has a component of movement parallel to the surface to be cut. This transverse movement can be effected by various types of drives, for example by an electric, mechanical, hydraulic or pneumatic drive, preferably by an electromagnetic drive, in particular with an electric coil and a guided therein magnet, which is mechanically connected to the separating element. Such a drive is characterized by a particularly low friction. Preferably, the magnet and / or the separating element is additionally connected to a spring, which supports the oscillating movement. The one- or multi-part separator may also be suspended eccentrically and in particular be designed as eccentric knife. Additionally or alternatively, as stated, the separating element can also be designed in several parts, for example comprising two mutually opposite saw blades or knives, in which case the carrier strip section has to be passed between the two knives or saw blades for severing the carrier strip section. When cutting then cuts a cutting edge on the underside, the other on the upper side, which is preferably done in a section in which the carrier strip portion is not yet wound on the carrier strip roll. Such a so-called parallel blade or such a so-called parallel saw, especially when suspended eccentrically, has the advantage that no part of the separating element blocks the transport path. Thus, when the carrier strip section is severed, the new loose end of the carrier strip section then formed may retract and, in the case of parts protruding into the transport path (cutting edge sections) of the carrier strip section Could catch separating element. A separating element in the form of a parallel blade (or a parallel saw), which is designed as an eccentric blade (or eccentric saw), but can be arranged so that retract both edges relative to the transport path, so that the loose end or the loose end portion can pass unhindered through the gap between the two separator elements.

In the case of using a two-part separating element, for example a parallel blade, where it is therefore necessary to pass the carrier strip section between the two separator elements, it is preferred if the slot width or opening of the separator, through which the carrier strip section must be passed, only a few millimeters is great. In this way, it can be prevented that a person inadvertently gets his fingers in the separator and in the area of action of the separating element. In particular, the slit width is in a range of 1 to 8 mm, preferably in a range of 3 to 8 mm, particularly preferably in a range of 3 to 5 mm. Finally, as flat as possible construction of the housing of the separator is advantageous, especially the lower housing part. The flatter this is, the shorter is the loose end to be led through the air.

According to yet another embodiment of the labeling machine according to the invention, the winding device further comprises a sensor device with at least one sensor for determining the position of the outer layer and / or the diameter or the radius of the carrier strip roll. Such a sensor can be used as a capacitive switch, ultrasonic sensor, laser or be executed mechanical limit switch. In principle, however, the sensor can also be designed to determine the weight of the carrier strip roll, that is to say for example in the form of a weighing cell; this (r) could then be arranged in the rotary shaft or the spool core. The sensor can then generate a corresponding signal or send it to a control device, which can then trigger corresponding follow-up actions (in particular severing and / or removing the label strip carrier strip section), as will be explained in more detail below. A sensor device is not mandatory. Thus, it is also conceivable that the control device is configured so that it can calculate from the known carrier strip thickness (which can be programmed or automatically measured) the time or the time window (time range) at which the said follow-up actions are to be triggered.

First, but again, the take-up device will be described in more detail. This has according to the invention as a fixing at least two, preferably at least three, more preferably at least four, parallel to the axis of rotation of the spool and parallel to each other, spaced apart in the radial direction pins. Radial is seen in relation to the axis of rotation of the spool core. In this case, all fixing means are preferably also spaced from this axis of rotation.

One or more of the fixing means or pins, preferably all fixing means or pins, may be between a protruding position and a retracted position to be moved. By the protruding position is meant a position in which the respective fixing means protrudes so far from the surface of the spool core that a fixing of the carrier strip portion, that is the loose end portion of the spool core is possible. Preferably, the respective fixing means protrudes in the protruding position at least as far as the carrier strip portion is wide. In other words, the length of the respective fixing means in the protruding position corresponds to at least the width of the carrier strip portion. By the retracted position is meant a position in which the respective fixing means protrudes less than in the protruding position or even not at all.

• Gemäß einer vorteilhaften Ausgestaltung sind vier Fixiermittel vorgesehen, die alle versenkbar sind, also zwischen einer hervorstehenden und einer zurückgezogenen Position bewegbar sind. Die Fixiermittel bzw. Stifte ragen vorzugsweise stirnseitig aus dem Spulenkern hervor und erstrecken sich parallel zur Rotationsachse des Spulenkerns. Die Fixiermittel bzw. Stifte haben alle denselben Abstand voneinander und haben auch den gleichen Abstand von der Rotationsachse des Spulenkerns. Die Stifte können einzeln oder paarweise oder alle zusammen versenkt werden, also in die zurückgezogene Position gebracht werden. Entsprechendes gilt auch für die Bewegung in die hervorstehende Position.

Various configurations and scenarios are conceivable, such as the fixing means or pins being movable between the protruding and the retracted position:

• According to an advantageous embodiment, four fixing means are provided, which are all retractable, that are movable between a protruding and a retracted position. The fixing means or pins preferably protrude from the end face of the spool core and extend parallel to the axis of rotation of the spool core. The fixing means or pins are all the same distance from each other and also have the same distance from the axis of rotation of the spool core. The pins can be individually or in pairs or all sunk together, so be brought into the retracted position. The same applies to the movement in the protruding position.

The above-mentioned fixing means or pins can also protrude different lengths or in the protruding position to different heights, in particular a pair of mutually opposite (with respect to the axis of rotation of the spool core) fixing means or pins of the same length.

In order to automatically fix the loose end portion of the carrier strip portion to the spool core at the beginning of the winding operation, it is conceivable that of the four fixing means or pins, two are initially sunk, that is, in the retracted position, and the other two are in the protruding position , In the event that the pins in the protruding position protrude different distances from the bobbin, the later less protruding pins initially sunk and protrude the more protruding pins out of the bobbin. The countersunk pins face each other with respect to the axis of rotation of the spool core, that is, the axis of rotation is located between the two recessed fixing means or pins. The same applies accordingly for the protruding fixative or pins. In this state, it is possible for the air outlet port to direct an air flow onto the carrier strip section and deflect it against the protruding fixation means or pins.

In this case, the position of the coil core, for the exemplary application that the coil core should not rotate at this moment, be chosen so that the protruding fixing means or pins are arranged on an imaginary line that is parallel or in an acute Angle of preferably less than 30 °, more preferably less than 15 °, to a straight line extending through the axis of rotation of the spool core and which bears tangentially on the surface of the guide element. If the position of the coil core at this time does not meet these requirements, the coil core is preferably rotated to a position that corresponds to the specifications, or the protruding fixing means or pins are sunk and the sunk fixing means or pins moved out. Once a suitable position of the bobbin and fixing means is set, the air outlet port can direct an air flow onto the carrier strip section and direct it against the two protruding fixation means or pins, whereby the carrier strip section passes through the area of action or rotation of the fixing means.

By the two previously sunk fasteners or pins are moved, it is achieved that the loose end portion of the carrier strip portion extends between at least two fixing means or on each side of the carrier strip portion at least one fixing protrudes.Durch the rotation of the spool core, the carrier strip portion jammed after one half turn of the spool so that a fixation of the loose end portion is achieved. In principle, it would also be possible to use only three or even two fixatives instead of four fixatives, whereby a comparable clamping effect would be achieved. In principle, and not according to the invention, it would also be conceivable to use only a single but slit fixing means, but in this case the loose end of the carrier strip section would have to be manually introduced into the fixing means slot.

Alternatively, it is also conceivable that at the beginning of the winding process to fix the loose end portion of the spool initially, all fixing or pins (four fixatives so all four fixing) are first sunk and with the help of an air flow from an air outlet of the Carrier strip portion is brought into the area of action or rotation of the fixing means. In order to simplify the positioning of the carrier strip section, an abutment element may be provided on the opposite side of the guide element, the surface of which preferably bears against an imaginary straight line passing through the area of action (rotation area) of the fixation means and in particular through the axis of rotation of the Spool core runs and bears tangentially on the surface of the guide element. The distance between the guide element and the coil core is smaller than the distance between the guide element and contact element. In other words, the axis of rotation of the spool core or of the spool core lies between the guide element and the abutment element. The air flow from the air outlet opening directs the carrier strip section against the contact element, so that the carrier strip section abuts both the contact element and the guide element and consequently extends through the effective region (rotation region) of the fixation means arranged between contact element and guide element. Then, when the fixing means or pins are moved to the protruding position, the carrier strip portion always extends between at least two of the fixing means. Jammed by the rotation of the spool core Accordingly, also in this case, the carrier strip section automatically.

In addition or as an alternative to the abutment element, provision can also be made for the air outlet opening to be oriented parallel to an imaginary straight line passing through the axis of rotation of the spool core and tangent to the surface of the guide element.

In addition or as an alternative, a plurality of air outlet openings of the type mentioned can also be provided for positioning the carrier strip section within the effective range (rotation area) of the fixing means, so that the carrier strip section is guided between two air streams or blow blasts.

Also additionally or alternatively, for positioning the carrier strip portion within the effective range (rotation range) of the fixing means may be provided that said area of action (rotation area) vertically below the outer edge (deflecting edge) of the guide element is arranged, so that alone by gravity of the carrier strip portion in the direction the area of action (rotation range) of the fixing means or in the direction of the axis of rotation of the spool core is directed. This can then be additionally supported by one or more directed air streams.

The use of a blower device with one or more air outlet openings may also be used for the loose end portion of the carrier strip section to steer in the slot or in the opening of the separator. Accordingly, according to one embodiment of the labeling machine according to the invention, the take-up device has a blower device with at least one air outlet opening, which is oriented such that a stream of air emerging therefrom separates the carrier strip section, in particular the loose end section thereof, into an inlet - meaning said slot or opening - the separating device directs. For this purpose, at least two air outlet openings of the type mentioned are preferably provided, which are aligned at an angle to one another and guide the carrier strip section between two air streams.

  • ∘ die Fixiermittel von der zurückgezogenen in die hervorstehende Position bewegen kann und/oder
  • ∘ die Rotation des Spulenkerns starten oder beschleunigen kann und/oder
  • ∘ die Gebläseeinrichtung ausschalten kann.

Finally, according to yet another embodiment of the labeling machine according to the invention, as already mentioned, a control device is provided. In particular, the takeup device has a control device that is configured in such a way that

• depending on a signal generated by the sensor or on a programmed or automatically measured carrier strip thickness value
  • o slow down a rotation of the spool core (in particular to adapt to the necessary transport speed) or stop and / or
  • o can operate the separator and / or
  • o can move the fixing from the protruding to the retracted position and / or
  • o the blower device can turn on
  and or
• that it depends on the throughput of the labeling machine
  • ∘ can move the fixing means from the retracted to the protruding position and / or
  • Starten can start or accelerate the rotation of the spool core and / or
  • ∘ can switch off the blower device.

In other words, in the case where it is determined by the sensor or by the calculation based on the known carrier strip thickness that the carrier strip roll needs to be exchanged at a certain time or within a certain time window, the control means is suitable at that time This time window to slow down or stop the rotation of the spool, to cause a severing of the carrier strip portion, sink the fixing means, whereby the role of the spool is released, and / or turn on the fan means, thereby to position the carrier strip portion before a new winding process can begin.

It should be noted that the rotation of the spool core does not necessarily have to be stopped in order to allow the roller to be released from the spool core or to cut through the carrier strip section. Rather, the spool core can continue to rotate at a constant or reduced speed. In this case, accordingly, no restart of the rotation of the spool core is necessary to initiate the rewinding process. In particular, the control device may be configured to match the rotational speed of the spool core to the necessary transport speed of the carrier strip portion and / or to the outer diameter of the wound carrier strip roll adapts; Thus, in the course of the winding process, the outer diameter and consequently the circumference of the winding carrier strip roll increases, whereby it is advantageous if the rotational speed of the coil core, in particular uniformly with increasing outer diameter), is reduced. Accordingly, the outer diameter and consequently the circumference of the roll is minimal at the beginning of a new winding operation, so that then the rotational speed is advantageously increased.

The control means may also, before starting the winding operation, move the fixing means from the retracted position to the protruding position thereby effecting fixation of the carrier strip portion at the beginning of the winding operation, by starting or accelerating the rotation of the spool core, starting the winding operation and / or the blower means for positioning of the support strip section within the effective range (rotation range) of the fixing means was turned off again.

It is also conceivable that the control device is configured to effect the severing of the carrier strip portion and / or the release of the carrier strip roll until a time when carrier strip is inserted into the labeling device. In this case, the control device must also check to what extent carrier paper in the device is postponed, and then initiate the process of severing and / or loosening accordingly.

• Zuführen eines Trägerstreifens (beispielsweise als Rollenware oder Liporello), der mit ablösbaren Etiketten versehen ist, in einer Transportrichtung zu einer Transfereinrichtung,
• Übertragen von in der Transfereinrichtung vom Trägerstreifen abgelösten Etiketten auf den mindestens einen zu etikettierenden Gegenstand, wodurch ein von Etiketten befreiter (vollständig oder teilweise befreiter) Trägerstreifenabschnitt erhalten wird,

• Durchtrennen des von Etiketten befreiten Trägerstreifenabschnitts, wodurch die Trägerstreifenrolle von dem übrigen Trägerstreifenabschnitt abgetrennt wird, und
• Lösen der abgetrennten Trägerstreifenrolle von der Aufwickeleinrichtung.

The object indicated above is also achieved by a method according to claim 10 for labeling articles such as goods or packaging, in particular using the previously described labeling machine, in which inter alia the following steps are carried out:

• Providing at least one object to be labeled,
• Supplying a carrier strip (for example as a roll product or Liporello) provided with detachable labels in a transport direction to a transfer device,
• Transferring labels detached from the carrier strip in the transfer device to the at least one article to be labeled, thereby obtaining a label strip section (completely or partially freed) that is freed of labels,
• Feeding a loose end portion of the label-removed carrier strip portion to a take-up device of a take-up device downstream of the transfer device,
• Winding the label-removed carrier strip section in the take-up device, thereby obtaining a carrier strip roll,
• Severing the label-removed carrier strip section, whereby the carrier strip roll is separated from the remaining carrier strip section, and
• Releasing the separated carrier strip roll from the take-up device.

Also by the inventive method is achieved that with relatively little technical effort and ease of use, the removal of the carrier strip or carrier paper is made possible, due to the achieved high (packing) density of the wound carrier tape role even under very economic conditions.

According to one embodiment of the method according to the invention, the loose end portion of the completely or partially liberated label carrier strip portion is automatically fixed in the winding device, in particular clamped. This is done in particular in the manner described above using the movable fixing means or pins.

According to yet another embodiment of the method according to the invention, as also described, the position of the outer layer and / or the diameter or radius or the weight of the carrier strip roll is determined during the winding process and a signal is generated when a predetermined reference value or reference value range is reached by a sensor. whereupon, preferably automatically, the severing of the carrier strip section is performed. However, as stated, the optimal time or window of severance can also be calculated by the controller based on a programmed or automatically measured carrier strip thickness value. For cutting the rotation of the carrier strip roll or the spool core must not be stopped as explained. The reference value or reference value range is chosen in particular such that a maximum number of windings (layers) of the carrier strip roll can be achieved without this with the outer layer abuts a part of the labeling machine and in particular the take-up device. The reference value range for the radius can be, for example, between 60 and 200 mm, preferably between 90 and 180 mm, particularly preferably between 150 and 160 mm. If the sensor detects such a radius, a signal can be generated which either indicates to an operator that the carrier strip roll has reached its desired size or automatically terminates the winding process, for example by severing the carrier strip section.

According to a further embodiment of the method according to the invention can also be provided that in the step of releasing (discarding) the separated carrier strip roll this is automatically released from the take-up device and in particular a subsequent winding automatically starts, as already explained. In principle, however, it is also conceivable for an operator to remove the carrier strip roll by hand. The same applies to the severing of the carrier strip section, which preferably takes place automatically, but in principle can also be carried out by hand.

It should also be pointed out once again that the rotation of the carrier strip roller is not necessarily stopped and accordingly the rotation of the spool core does not necessarily have to be started after the removal of the carrier strip roller, since the release or ejection of the carrier strip roller and also the severing of the carrier strip section during the process Rotation of the bobbin can be done.

Fig. 1 shows a schematic diagram of a labeling machine 1 according to the present invention, which has a labeling device 2 and a winding device 6. The labeling device 2 has a Feeding device 2.1 for supplying a carrier strip 3, which is provided with detachable labels 4, and a transfer device 2.2 for transferring the labels 4 from the carrier strip 3 to an object 5 to be labeled. The object to be labeled 5 is transported, as shown by arrows, on a conveyor belt 8 or the like by the transfer device 2.2, wherein, as in Fig. 1 is shown, before entering the transfer device of the article 5 (left object in Fig. 1 ) yet bears no intended label 4, whereas after passing through the transfer device 2.2 of the article 5 (right object in Fig. 1 ) is covered with a label 4.

As stated, the labels 4 are detachably applied to a carrier strip 3, which is provided here as an endless roll 3.3. The carrier strip 3 is unrolled from this endless roll 3.3, guided by the transfer device 2.2 and then, after the carrier strip 3 is completely or partially freed from the labels 4, fed to a take-up device 6.

Embodiments of a winding device 6 show the FIGS. 2a to f).

Basically, in the take-up device 6 of the liberated from the label 4 section 3.1 of the carrier strip 3 is wound, whereby a carrier strip roll 3.2 is formed. In order to be able to automatically fix a loose end section 3.11 of the carrier strip section 3.1 in a take-up device 6.2 of the take-up device 6, a blower device 6.3 is used as auxiliary device provided that can direct a directed air flow S for the exact positioning of the end portion 3.11 on the carrier strip section 3.1. A sensor device 6.5 recognizes when the carrier strip roll 3.2 has reached a predetermined size, whereupon the carrier strip section 3.1 can be severed via a separating device 6.4. The carrier strip roll 3.2 can then be released and removed from the take-up device 6, whereupon a new winding process can begin. The removed from the take-up 6 carrier strip roll 3.2 can then be disposed of.

The embodiments in the FIGS. 2a ) to f) have in common that the winding device 6 has a guide device 6.1 with a guide element 6.11, on which the carrier strip section 3.1 in a transport direction T is guided along, and a winding device 6.2, which is connected downstream of the at least one guide element 6.11 and 6.21 has the fixing means, in which a loose end section 3.11 of the carrier strip section 3.1 is fixable, wherein the fixing 6.21 are arranged on a rotatable about a rotation axis X spool 6.22 and follow a rotational movement of the bobbin 6.22.

Furthermore, the take-up device 6 according to the schematically illustrated embodiments in the FIGS. 2a ) to f) a blower 6.3 with at least one air outlet opening 6.31, which is oriented such that an air flow S exiting therefrom the carrier strip section 3.1, after this Guide element 6.11 has happened, in the direction of the bobbin 6.22 directs.

In addition, the individual embodiments of the winding device 6 also have a separating device 6.4 with a separating element 6.41, for example a knife, a saw blade or a rotatable cutting disk, wherein the separating element 6.41 is movable to a position in which a severing of the carrier strip portion 3.1 can be carried out , The separating element may also be formed as a laser cutting head in the illustrated embodiments, wherein the section is then effected by heating the carrier strip portion 3.1 by means of the laser beam.

Finally, the take-up device 6 in all the examples shown on a sensor device 6.5, which is provided with at least one sensor 6.51, which is suitable for determining the position of the outer layer 3.12 and / or the diameter or radius of a carrier strip roll 3.2 by means of the winding 6.2 from the carrier strip section 3.1 has been generated. It is also conceivable to provide a sensor which determines the weight of the carrier strip roller 2.3; this could then be arranged in the rotary shaft or the bobbin 6.22.

According to Fig. 2a ) are arranged as fixing 6.21 four pins 6.21 6.22 on the bobbin, which extend parallel to the axis of rotation X of the bobbin 6.22 and parallel to each other and which are spaced from each other in the radial direction r. The pins 6.21 have all the same distance to each other and also have to the rotation axis X all the same distance. The pins 6.21 are all movable between a protruding position and a retracted position. Of the four pins 6.21 can, in order to start a winding process, initially two each opposite each other, between which thus the axis of rotation X runs, be arranged in the protruding position (pins in Fig. 2a each symbolized by dark dots), while the other two pins, which are also opposite, are in the retracted position (pins in Fig. 2a each symbolized by bright dots).

The two protruding pins 6.21 serve as an abutment for the end of the spool core 6.22 3.11 of the carrier strip portion 3.1. Thus, the end section 3.11, after it has passed the guide member 6.11, directed by an air flow S from the air outlet opening 6.31 in the direction of the bobbin 6.22 and the two protruding pins 6.21 until the end portion 3.11 comes to rest on the two protruding pins (this initial position of the end section 3.11 before the beginning of the fixing and the winding process is in the FIGS. 2a ) to f) (shown in dashed lines). In this particular case, at the moment when the end portion 3.11 contacts the pins 6.21, the bobbin 6.22 has a position such that the protruding pins 6.21 are disposed on an imaginary line G parallel to a line G 'passing through the Rotation axis X of the bobbin 6.22 runs and which bears tangentially on the surface of the guide element 6.11.

The two previously sunk pins are then also moved to the protruding position, whereby the end portion 3.11 jammed between the pins 6.21. The blower 6.3 is then turned off. As soon as the sensor 6.51 determines a certain thickness of the carrier strip roll 3, a corresponding signal is transmitted to a control device 6.6. The separating device 6.4 then severed the upper layer 3.12 of the wound to a roll 3.2 carrier strip portion 3.1. For cutting, the rotation of the bobbin 6.22 can be stopped or slowed down. However, the bobbin 6.22 can also rotate at a constant speed during the cutting.

The severing takes place, for example, by means of a separating device, as in Fig. 3a ) is shown. In the Fig. 3a ) has a saw blade 6.41, which is mounted eccentrically and thereby performs a movement having a vertical and a horizontal component. The vertical component of motion is referred to herein as stroke H. The stroke H is for example 1 to 2 mm. In the lower lifting position, the saw blade 6.41 touches the surface of the carrier strip section 3.1 to be severed. In this case, the saw blade 6.41 in the vertical direction, ie in the direction of the lifting movement, resiliently suspended (not shown), so that a certain pressure force of the saw blade 6.41 is not exceeded at the surface to be cut. The horizontal movement component is caused by a horizontally oscillating drive, in Fig. 3a ) For example, by an electromagnetic drive 6.44 with a guided in an electric coil magnet. The severing can also be done by means of a parallel knife 6.41, as it is in Fig. 3b ) is shown and will be described below. Alternatively, a separating device 6.4 with several needles 6.45 may be provided ( Fig. 3c ), which serve to perforate the carrier strip portion 3.1, so that it tears at this point independently.

In the embodiment according to Fig. 2a ) are, after the cutting is done, sunk all four pins 6.21, whereby the carrier strip roller 3.2 is released and can be disposed of.

The non-inventive embodiment of a winding device 6 in Fig. 2b ) is similar. However, here are the four pins 6.21 always moved simultaneously in the retracted or in the protruding position. In order to be able to fix the end section 3.11 to the pins 6.21 before starting the winding process, all the pins 6.21 are initially sunk, whereupon the air flow S from the air outlet opening 6.31 directs the still loose end section 3.11 in the direction of a straight line G passing through the axis of rotation X of the coil core 6.22 runs and which bears tangentially on the surface of the guide element 6.11. In this case, the end section 3.11 comes to a contact element 7 to the plant whose surface is also applied to the imaginary straight line G. In this way it is ensured that the carrier strip portion 3.1 passes through the rotation range of the pins 6.21 and is automatically jammed by the pins 6.21 in the extended state.

Another difference between Fig. 2a) and Fig. 2b ) is that according to Fig. 2a ) of the bobbin 6.22 vertically below the outer edge of the guide element 6.11 is located, so that the gravity supports the positioning of the still loose end section 3.11 in the region of the bobbin 6.22. According to Fig. 2b ), the spool 6.22, however, is not vertically below the outer edge of the guide member 6.11, but offset laterally to the labeling device 2 out. The offset can also be provided in the other direction, that is, away from the labeling device 2.

Both in the case of Fig. 2a ) as well as in the case of Fig. 2b ), the air flow S is oriented at an angle to an imaginary straight line which runs through the axis of rotation X and bears tangentially on the guide element 6.11. According to Fig. 2c ), the air flow S, however, is parallel to an imaginary line G, which passes through the axis of rotation X and tangentially abuts the surface of the guide member 6.11. In the latter embodiment, is achieved by the parallel orientation of the air flow S, that the still loose end section 3.11 moves without the need of a contact element 7 in the rotation range of the pins 6.21. The embodiment according to Fig. 2c ) agrees with the in Fig. 2b ), where in Fig. 2c ) has been dispensed with said abutment element 7.

Fig. 2d ) shows an embodiment of a winding device 6, which with the in Fig. 2a ) substantially matches. However, it is also according to Fig. 2d ) provided a parallel flow of the still loose end section 3.11, whereas the flow in Fig. 2a ) is selected angularly.

In the embodiment in Fig. 2e ) takes place as in the embodiment in Fig. 2d ) also a parallel flow of the loose end portion 3.11 by the air flow S, but here the separator 6.4 is not arranged laterally on the roller 3.2, but vertically above the roller in a region in which the carrier strip section 3.1 is not yet wound on the roll , therefore not yet the guide element 6.11 has happened. The latter forms here the exit from the separator 6.4, so that in this embodiment, the guide member 6.11 part of the housing of the separator 6.4.

The separator 6.4 has according to Fig. 2e ) a two-part separator 6.41 in the form of a parallel blade on. This is schematic in Fig. 3b ). The two blades of the parallel blade 6.41 are each mounted eccentrically and perform a mutually synchronous movement with a vertical component and a horizontal component, wherein as in Fig. 3a ) Here, too, the horizontal component is effected by an electromagnetic drive 6.44 with a guided in an electric coil magnets. The latter is additionally connected to support the oscillating movement with a spring 6.43. Such a parallel blade has the advantage that the blades severing the carrier strip section 3.1 from above and below can be withdrawn so far from the transport path that after severing the new end section 3.11 without the risk of getting caught by the gap between the cutting edges can be performed.

In order to further support the guidance of the end section, an additional blower device 6.3 'in the Embodiment according to Fig. 2e ), which has two air outlet openings 6.31 ', one of which is arranged below and above the carrier strip section 3.1. The two exiting air streams S 'are aligned at an angle to the transport direction T and allow a previously separated loose end portion of the carrier strip section 3.1 in the opening or the inlet 6.42, which is funnel-shaped here, to direct the separator 6.4.

In addition, according to the embodiment as well Fig. 2e ) a sensor device 6.5 is provided with a sensor 6.51, which can determine the position of the outer layer 3.12 of the carrier strip roll 3.2.

Fig. 2f ) shows yet another embodiment, which substantially with the in Fig. 2e ), but in the embodiment in FIG Fig. 2f ) of the bobbin 6.22, in particular its axis of rotation, lies in the same plane in which the carrier strip section 3.1 is supplied from the labeling device 2. In this specific example, this plane, in which the lower edge of the guide element 6.11 extends, extends in the horizontal direction. Here, therefore, the carrier strip section 3.11 of the guide element 6.11 at the moment when a new winding process begins, just continued in the horizontal direction to the bobbin 6.22. In order to ensure the guidance of the end section 3.11 from the guide element 6.11 to the coil core 6.22, two air outlet openings 6.31 are provided in this embodiment, one of which is arranged below and one above the carrier strip section 3.1. The air streams S occur in the same direction and at the same angle to the transport direction T as the air streams S 'of the air outlet openings 6.31' from.

The FIGS. 4a ) and b) show in perspective a bobbin 6.22 respectively in the state in which all the pins 6.21 protrude completely. It shows Fig. 4a ) An embodiment in which the pins 6.21 all protrude equally far while Fig. 4b ) shows an embodiment in which the pins protrude to different extents in the fully protruding position. The protruding in this position pins 6.21 then serve to abut the end portion of the carrier strip portion 3.1, the less protruding pins serve to fix this end portion for the purpose of winding.
