Description

The present invention relates to a supply roll having a roll core and flat and / or strip material which is supported by a plurality of windings of the roll core.

Such stock rolls can be used for example in the field of packing technology. Devices are known which provide uninterrupted flat and / or strip material from a supply of material in order to wrap articles with the flat and / or strip material and mechanically combine them. Thus, the flat and / or strip material, for example, be formed as a shrink film, wherein a plurality of beverage containers are wrapped by means of the shrink film and combined into containers.

If the stock of flat and / or strip material of a roll is exhausted, the roll must be replaced by another roll with new flat and / or strip material in order to continue an embarked packaging process and preferably perform uninterrupted.

Devices that have an uninterruptible packaging process allow appropriate supply rolls that can be used for a seamless packaging process, are, for example, from DE 195 22 110 A1 known. In this known device two parallel shafts are provided, sit on which supply rolls. From the supply rolls shrink film is unwound and placed around articles. The articles then pass through a shrink tunnel. If the stock of shrink film of a roll is exhausted, then shrink film of another roll is connected to the strip supply of the first roll by means of welding.

If the shrink films of two rolls are to be joined by means of welding, a free end region of a new roll is first to be removed from this and, for the purpose of welding, to be moved in the direction of the further roll. Frequently, the position of the free end portion is unknown, so that the new role must first be manually rotated or oriented, whereupon the free end portion is moved in the direction of the other role to this with shrink film to the other role weld. With automated implementation, this can be associated with problems. Manual alignments are cumbersome and associated with human resources.

A primary object of the present invention can therefore be seen to provide a supply roll, can be replaced in a simplified manner and while avoiding problems already used up supply roll. A further object of the invention is to provide an at least partially automated device or a method for handling flat and / or strip material, by means of which supply rolls can be simplified and exchanged while at least largely avoiding problems.

These stated objects are achieved by a supply roll, a method and an apparatus which comprise the features of the respective independent claims. Further advantageous embodiments are described by the dependent claims.

To achieve the stated object, the invention proposes a supply roll comprising a roll core and flat and / or strip material, which is supported by a plurality of windings of the roll core. The roll core can in principle consist of almost any material and, for example, be formed by cellulose or plastic and also have a cylindrical or hollow cylindrical shape in particular. If the supply roll is used in the field of packaging technology, the flat and / or strip material may, for example, be formed by shrink film or stretch film, i. by shrinkage under the effect of temperature film or by stretchable film.

Next, the supply roll has at least one adhesive mark which is connected to an outer free end region of the flat and / or strip material and at least partially connected to the free end region adjacent outer layer of the flat and / or strip material by an adhesive bond.

It can be provided that information about the relative position of the free end region can be visually recognized via the adhesive marking. The adhesive marking may, for example, be in the form of an adhesive marking or comprise at least one broadside surface proportionately or completely an adhesive agent application. Thus, an adhesive bond can be formed between the adhesive marking and the outer free end region and the outer layer adjacent to the outer free end region.

However, the invention is not limited to embodiments with only one adhesive mark. Thus, it is also conceivable that in various embodiments two adhesive markings or more than two adhesive markings are provided which are each connected in a defined relative position with the free end region of the flat and / or strip material of a supply roll.

Since the adhesive marking can be applied in a defined relative position to the outer free end region of the flat and / or strip material and the outer layer adjacent to the free end region, it is conceivable that conclusions about the actual position or the actual position can be obtained by optical recognition of the adhesive marking. Alignment of the outer free end region are taken.

The adhesive marking or the adhesive marking can be glued both to the outer free end region and to the outer layer of the flat and / or band material. If more than one adhesive mark is present, then all adhesive markings of the respective supply roll can fix the free end region to an outer layer of the flat and / or strip material which is adjacent to the free end region. Advantageously, the free end region can retain its relative position on the roll as a result of the bonding. The risk of unintentional unwinding of flat and / or sheet material from the supply roll is thereby reduced.

It may also be expedient that the adhesive marking has at least one marking which assigns the adhesive marking a specific rotational position and / or rotational direction with respect to the terminal edge of the outer free area. In this case, the at least one marking can be designed and positioned in such a way that the course of the terminal edge of the outer free end region can be detected optically or in another way by means of the at least one identification, for example by means of ultrasound scanning and detection. Practice has shown that in principle such adhesive markings can also be applied by hand or manually to the outer free end region, without thereby having to lack the necessary precision of the positioning. In addition, it may be that the bonding of the adhesive marker with the respective free end region is automated and / or machined.

The adhesive marking also comprises a region without an adhesive bond and / or a non-adhesive region, which region without adhesive bond and / or non-adhesive area is at the level of a terminal edge of the outer free end region. It is also provided that in the area without adhesive bond and / or in the non-adhesive area, a perforation is introduced into the adhesive marking over which perforation the adhesive mark for releasing the free end portion of the free end region adjacent outer layer is separable.

In addition to the variants mentioned further meaningful modifications and / or additions of the markings or optical markings or markings into consideration, to assign the adhesive marking a certain rotational position with respect to the end edge of the outer free end portion. For example, a symbolism, such as an arrow representation or the like may be provided which refers to the corresponding specific rotational position for the adhesive marking with the aid of the end edge.

The supply roll may also comprise a so-called RFID transponder on which information about the supply roll is stored. Thus, for example, information about the number of turns, the nature of the respective flat and / or strip material, the amount of the longitudinal extent of the supply roll and / or further information can be stored on the RFID transponder. The information from the RFID transponder can then be read out via a corresponding RIFD transceiver and, if appropriate, displayed on a display or on a display and / or used for setting and / or working parameters of the packaging machine. The RFID transceiver can be arranged in the region of an installation position for the supply roll or in the region of a holding mandrel. It is also conceivable that a handling device, which places the respective supply roll on a retaining pin, carries the RFID transceiver.

The RFID transponder can be fixed on the flat and / or strip material of the respective supply roll and, for example, adhesively bonded to the flat and / or strip material of the respective supply roll. In particularly preferred embodiments, the RFID transponder can optionally also be designed as part of the adhesive marking and / or attached or integrated therewith.

It is also conceivable that the adhesive marking has an optosensory detectable QR code, which in coded form corresponding information, as previously mentioned, may contain the supply roll. In addition, further codings such as so-called barcodes or barcodes are suitable for supplementing the Adhesive marking, with the help of such information carrier or encodings contain more or the above-mentioned information about the supply roll, transmitted and recorded.

Furthermore, the invention relates to a method for handling wound on stock rolls flat and / or strip material, in which method at least one adhesive mark with an outer free end portion and at least partially adjacent to the outer free end portion outer layer of flat and / or Band material is connected to a supply roll and the supply roll is placed on a retaining pin. The method further provides for optical recognition of the location of the adhesive mark and alignment of the outer free end region depending on the optical detection performed. Following this time, the outer free end region is gripped and pulled off the supply roll. Upon removal of the outer free end region, the adhesive marking is separated at a perforation, as a result of which a part of the adhesive mark remains on the outer free end region and another part of the adhesive marker remains on the outer layer adjacent the outer free end region of the supply roll.

The adhesive marking can be applied or glued onto the supply roll in a previous step, for example, so that the perforation lies at the level of a terminal edge.

As mentioned above, the position of the adhesive mark is optically recognized in a process step. For this purpose, optical sensors and / or, for example, at least one camera system with downstream image evaluation can be provided in order to optically recognize the position or position of the adhesive marking. It is conceivable, for example, that the position or position of the adhesive marking is optically recognized and the supply roll is then placed on the holding mandrel. Thus, for example, a suitable and appropriately equipped handling device can be provided which has an optical sensor or a camera system which detects the position or position of the adhesive marking and, in terms of time, places the supply roll on the holding mandrel, so that the outer free end region or the adhesive marker has a specific orientation or position.

However, it is also conceivable that one or more optical sensors in the region of the retaining pin or in the region of a respective installation position for the supply roll are positioned and recognize a position of the adhesive marker after placing the supply roll on the retaining mandrel. If the position of the adhesive marker does not coincide with a predetermined desired position, the retaining mandrel can rotate the supply roll until the position of the adhesive marker coincides with a predetermined desired position. Thus, in a further method step, the outer free end region is aligned as a function of the optical recognition. The outer free end region can be aligned by a rotation of the retaining mandrel, on which the respective supply roll is seated.

Furthermore, it is conceivable that an optical sensor or else a plurality of optical sensors in the region of the packaging machine or of the retaining pin or on the handling device recognize the actual condition of a marking of the adhesive marking on the supply roll. As a result, conclusions about the temperature, humidity, etc., of the supply roll can be concluded, for example.

Practice has shown that adhesive markings can be readily recognized when the adhesive marker has areas of high contrast on a broadside surface facing away from the supply roll. Thus, at least one first recognizable region of the adhesive marking may be formed black and at least one further region, which optionally adjoins or directly adjoins the first region, is white and / or transparent.

In a further method step, the outer free end region, as already explained above, gripped and withdrawn from the supply roll. For this purpose, for example, a suction and / or gripping device or a suction rod may be provided which detects the outer free end region via negative pressure and leads away in the direction of the supply roll. Since this step takes place after the adhesive marking or the outer free end region has been aligned, the outer free end region can be selectively and problem-free picked up by the suction and / or gripping device and pulled off in the direction of the respective supply roll or in the opposite direction of the respective supply roll become. In the case of packaging machines, the outer free end region can subsequently be connected to flat and / or strip material already running in the packaging machine, which if necessary is unwound from a further supply roll of a further installation position. For this purpose, for example, a vertically movable welding rod can be provided, which moves the outer free end region against the already guided in the packaging machine flat and / or strip material.

The invention also relates to an adhesive marker for attachment to a supply roll. The adhesive marking comprises at least two adhesive areas and at least one non-adhesive area lying between the adhesive areas. It is envisaged that the adhesive marking comprises a perforation and / or perforation line which lies in the non-adhesive region of the adhesive marking and over which the adhesive marking can be separated into two separate parts.

It is also conceivable that the adhesive marking is connected at least approximately centrally with respect to a terminal edge of the outer free end region with the outer free end region and the outer layer adjacent to the outer free end region. As already mentioned above, the adhesive marking for this purpose may have one or more markings to connect the adhesive marking at least approximately centrally and / or with a specific position or rotational position with the outer free end region. In particular, embodiments have proven in which the at least one marking is formed by a marked or colored, in particular black formed, triangular shape, wherein within the triangle shape, in turn, a T-shape is introduced, which deposed in color of the triangular shape is or is transparent in particular.

The adhesive marking is connected to an outer, free end region of the flat and / or strip material and to an outer layer of the flat and / or strip material adjacent to the outer free end region, so that the adhesive marking matches the outer free end region on the outer fixed and fixed adjacent position of the flat and / or strip material.

The non-adhesive portion of the above-described adhesive mark may be particularly formed in an area without adhesive or adhesive agent or without other adhesives or bonding agents.

The adhesive marking may have a marking, by way of which at least one information about the direction of rotation of a supply roll is provided.

In addition, the adhesive marking may have a marking, via which at least information about the position of the at least one perforation is provided. The adhesive mark can be attached to the supply roll in such a way that the at least one perforation lies at the height of the previously mentioned closing edge.

In addition, the adhesive marking may have a marking, via which at least information about the actual condition of a supply roll is provided. For example, the actual condition can be represented by a mark, which changes its property, in particular its color in the wet, heat, humidity or age.

Furthermore, the adhesive marking may be formed such that the perforation and / or the non-adhesive area are colored or shaded or the like. Marked or are deposited.

In addition, information or markings above and / or below the perforation attached, printed, glued and / or integrated.

Optionally, it may also be useful to provide adhesive markings in which the respective perforations and / or the perforation lines and / or the non-respective adhesive area are marked in a sensory detectable manner and / or prepared with for a sensory recognition, so that they, for example . Detected by optical sensors and thus their position can be determined exactly.

The following statements again summarize some aspects of the invention previously explained in various embodiments, concretizing some aspects, but should not be contradicted by the statements already made, but in synopsis, if necessary, as more specific embodiments and / or modifications. Thus, the supply rolls according to the invention can be handled in particular by means of so-called film roll modules, which can normally be parts of a packaging machine, not specifically explained here, in particular a shrink wrapping machine. A supply roll is usually used in this case by a suitably equipped and suitable handling device in the mentioned film roll module. The film roll module may, for example, have two or more installation positions for the rolls. Thus, for example, one of the supply rolls can be placed on a rotatable mandrel, while another supply roll can be in or in a second installation position. During the insertion of one of the supply rolls flat and or strip material is withdrawn from the other or at least one further supply roll and supplied to the packaging machine not specified here.

As the invention provides, for example, two adhesive marks may be mounted on the supply roll, which is a direction of rotation compliant alignment of Display the supply roll and an end edge of a free end portion of the sheet material wound on the supply roll. The direction of rotation compliant alignment and the end edge are usefully sensed respectively by sensors or jointly by a sensor. In particular, the adhesive marking can fix or fix the free end region of the flat and / or strip material to an outer layer of the flat and / or strip material which is adjacent to the free end region. The adhesive marking is thus adhered both to the free end region and to the outer layer, so that the free end region or the flat and / or strip material is fixed to the roll and can not be unintentionally unwound.

In the area of the installation position of a roller, an optical detection device can furthermore be arranged which, for example, can be designed as a camera system. About such an optical detection device, a position of the adhesive mark can be detected. The handling device, an actuator and the optical detection device or the camera system are preferably connected to a control device which is likewise not specified here. If the position of the adhesive marking has been recognized by the optical detection device or by the camera system, the control device optionally provides a rotating movement of the retaining mandrel, so that the adhesive marking is thereby brought into a predetermined or defined desired position. An optional existing movable suction and / or gripping device or a suction bar can then detect the free end of the supply roll and remove. Following this, the flat and / or strip material or the shrink film of the supply roll can be welded to a flat and / or strip material or a shrink film of the further supply roll in a non-detailed process.

The roll cores of the rolls may be formed, for example, from cellulose or plastic or other suitable material and are normally formed as a hollow cylinder. Due to the hollow-cylindrical shape of the roll core, each supply roll or the roll core can be placed on a holding mandrel or taken up by a handling device and attached to a holding mandrel. The roll core carries flat and / or strip material with a plurality of windings. The flat and / or strip material may be formed, for example, as a shrink film or stretch film. Furthermore, the supply roll comprises an adhesive mark. Stock rolls may have a different longitudinal extent or width according to need and processing programs, and may have a different number of sticky marks. While with relatively narrow supply rolls, for example, only one Adhesive marking may be present, have slightly wider stock rolls if necessary, two or more juxtaposed and each spaced-apart adhesive marks.

In the region of the perforation, the adhesive markings may optionally not be adhesively bonded to the free end region and to the layer adjacent to the free end region, but may be applied only to the supply roll. The bonding and fixation can instead be achieved via two adhesive areas in the upper and lower areas of the adhesive marking.

The adhesive markings may each have two adhesive or self-adhesive areas on the rear side and a non-adhesive or non-adhesive area. The front side of the adhesive marking may have, for example, an identification in the form of a triangle or the like, wherein a T-shape rotated by 180 ° may be included in the triangular shape. The triangular shape can also be color-coded from the adhesive label to ensure sensory recognition or recognition. The rotated by 180 ° T-shape can optionally be transparent or transparent.

In addition, it can be provided that the adhesive marking has a perforation or perforation line which extends over the longitudinal extent of the adhesive marking or width of the adhesive marking in the non-adhesive or in the non-adhesive region. When the free end region is removed from the supply roll, the adhesive marking separates at the perforation or at least partially along the perforation line. The upper adhesive portion of the split upper adhesive marker half remains joined to the peeled free end portion and the lower adhesive portion of the split lower adhesive marker half is connected to the outer layer adjacent the free end portion.

The tip of the optional triangular shape indicates the position of the perforation or perforation line of the adhesive marker. The adhesive marking is applied to the supply roll in such a way that the perforation or perforation line lies at the level of the terminal edge of the free end region and a partial region of the free end region and a partial region of the outer layer adjacent to the free end region lie in the adhesive regions of the adhesive label. The adhesive areas are preferably self-adhesive. The non-adhesive or non-adhesive area around the perforation ensures removal of the free end area even if the perforation or perforation line is not exactly level the terminal edge is positioned. Preferably, the non-adhesive or non-adhesive region has a height of a few millimeters (eg about 3 mm) and for example about 30 mm. The perforation or perforation line is located in or at least approximately in the middle of the height of the non-adhesive or non-adhesive region.

In a further embodiment variant, the triangular shape with the integrated transparent T-shape rotated by 180 ° can also be designed as an adhesive strip, which can be glued onto the adhesive marking. Alternatively, however, the triangular shape may be printed on the adhesive marker, wherein the T-shape rotated by 180 ° is formed as a non-printed part in the triangular shape and thus the adhesive mark in this area not printed or not in the same color as the Triangle shape is printed. The mentioned perforation can optionally be formed by recesses or holes or slots in the adhesive marking. The recesses or holes or slots can be introduced by punching, laser cutting or the like. In the adhesive marker.

The non-adhesive area or non-self-adhesive area can be marked or marked on the front side of the adhesive marking, for example by a marking or marking. This allows a user or user a reliable application of the adhesive mark on or on the supply roll. The adhesive marking is applied in such a way that the non-adhesive region at least partially covers the free end region and the outer layer adjacent the free end region, so that the adhesive marking in the region of the perforation is not adhesively bonded to the free end region and the outer layer adjacent to the free end region ,

If the position of the adhesive mark is detected, conclusions about the position of the free end region as well as the position or dimensioning of the supply roll can be made. A detection of the free end region after optical recognition of the adhesive mark and a deduction of the free end portion of the supply roll are then easily possible.

The front side of the adhesive marker can optionally be provided with an additional information surface or marking, which can be arranged in particular on the lower part of the adhesive marker. On such a label further information on the nature of the supply roll can be deposited, including information about the number of turns, the nature of the respective flat and / or Band material, the amount of the longitudinal extent or width of the supply roll and / or other information. By means of a corresponding sensor or a camera sensor, it is then possible to read out the information and make it available to a control device of the packaging machine not specified here.

On the front side of an adhesive marking information on the nature of the supply roll can also be optionally provided by means of a QR code. Inter alia, information on the number of turns, the nature of the respective flat and / or strip material, the amount of the longitudinal extent or width of the supply roll and / or other information is deposited. By means of a suitably equipped and configured QR-camera sensor, it is then possible to read out the information and make it available to a control device of the packaging machine. Alternatively, the QR code can also be read out with an operator device of an operator or user. Furthermore, the front of the adhesive marker optionally contains a further information or marking for the direction of rotation compliant alignment, which may be applied there in the form of an arrow.

The perforation line and the attachment of the adhesive marking on the terminal edge of the free end area is indicated by the optionally color-coded or color-contrasted or marked areas at the level of the perforation line.

In a further variant of the adhesive marking markings or markings can be provided on opposite sides of the perforation line on the front, which make the position of the perforation line or the area around the perforation visible. This enables a user to reliably apply the adhesive marking to the respective film roll.

The front side of a further embodiment variant of the adhesive marking can, for example, have or carry an RFID transponder which is firmly connected to the adhesive marking. On the RIFD transponder information about the respective supply roll, to which the adhesive label is affixed, can be deposited. It is conceivable here that information about the number of turns, the type of the respective flat and / or strip material, the amount of the longitudinal extent of the supply roll and / or further information are stored on the RFID transponder, for example. By means of a corresponding RFID reader, which can be arranged, for example, in the region of an installation position for the rollers, it is then possible to use the RFID transponder read. If information on the number of turns of the supply roll is stored on the RFID transponder, it can be provided that a packaging machine is controlled after reading the RFID transponder, taking into account the stored information. By optionally deposited number of windings, the packaging machine may possibly indicate a necessary replacement of the supply roll or cause an exchange or replacement of the almost completely applied supply roll or perform automated. The mentioned embodiment of the adhesive label with an RFID transponder is to be understood as an example. Thus, it can be provided that the adhesive label instead of the RFID transponder or in addition to the RFID transponder by means of suitable codes provides information on the supply roll available. The codings can be formed, for example, as a QR code, as a bar code and / or further coding.

According to a further embodiment, the perforations or perforation lines may be colored on a front side of the adhesive marker. In addition, other markings are possible to indicate the corresponding relative position for the adhesive mark and the perforation of the adhesive mark on the free end region and possibly its central alignment on the supply roll. Further embodiments for the markings can be provided to refer to the corresponding relative position for the adhesive marking and the perforation of the adhesive marking at the free end region and possibly its central alignment on the supply roll.

In an alternative embodiment of a perforation of the adhesive marking with marking can be provided that the perforation over the longitudinal extent or width of the adhesive marker tapers in one direction. The taper may, for example, be formed by two aligned perforation lines. Alternatively, the entire surface between the perforation lines may be perforated. The perforation is usefully arranged in a non-adhesive area of the adhesive label.

Optionally, the adhesive marking on the sides, at the level of the perforation line, may have additional indentations, e.g. to facilitate the separation along the perforation line and ensure.

Optionally, two perforation lines may extend over the length of the adhesive marker. The area around the perforations may preferably be marked to visually identify the non-adhesive area on the front of the adhesive marker.

A suitable suction and / or gripping device or a suitable suction rod may be provided to separate the free end region of the adjacent outer layer and deduct from the supply roll or unwind or tap. The sticking or gripping force of the suction bar separates the adhesive marking on the perforation along the perforation line.

Finally, it should be emphasized at this point that all aspects and variants, in connection with the supply roll according to the invention with its at least one attached there adhesive marking equally on the inventive method for handling wound on supply rolls flat and / or strip material and / or a can refer to the aforementioned and explained variants of the method. In addition, all aspects and variants relating to the supply roll according to the invention with its at least one adhesive marking applied there may equally refer to the adhesive marking according to the invention itself and / or to a variant of the adhesive marking associated therewith. The same applies in the reverse direction, so that all aspects mentioned in connection with the method according to the invention for handling flat and / or strip material wound up on supply rolls and / or in connection with one of the previously mentioned and explained variants of the method are equally applicable to one Embodiment of the supply roll according to the invention and / or refer to a variant of the invention adhesive label and may be related to it, without this had to be separately mentioned above.

For identical or equivalent elements of the invention, identical reference numerals are used. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are merely examples of how the invention may be configured and are not an exhaustive limitation.

The schematic view of Fig. 1 shows a variant of a so-called. Film roll module 1, which may be part of a not completely shown here packaging machine, in particular a shrink wrapping machine. A supply roll 5 is inserted by a handling device 10 into the film roll module 1. The film roll module 1 has two installation positions 14 and 14 *. The supply roll 5 is placed on a rotatable mandrel 15, while another supply roll 5 * is in the second installation position 14 *. During the onset of the Stock roll 5 is subtracted from the supply roll 5 * flat and or strip material 8 and fed to the packaging machine not shown here.

On the supply roll 5 two adhesive marks 2 are mounted, which indicate a direction of rotation conformal alignment of the supply roll 5 and a terminal edge 18 of the free end portion 7 of the supply roll 5. The direction of rotation conforming alignment and the end edge 18 are each or together sensory detected by a sensor 30, 30 *.

The schematic view of Fig. 1 shows, moreover, that the adhesive marking 2 fixes or fixes the free end region 7 of the flat and / or band material 8 at an outer layer 11 of the flat and / or band material 8 which is adjacent to the free end region 7. The adhesive marking 2 is thus adhered both to the free end region 7 and to the outer layer 11, so that the free end region 7 or the flat and / or strip material 8 is fixed to the roll 5 and can not be unintentionally unwound.

According to Fig. 1 is in the field of installation position EB an optical detection device 30 * arranged, which may be formed, for example, as a camera system 32. By way of the optical detection device 30, 30 *, a position of the adhesive marking 2 can be detected. The handling device 10, the actuator 40 and the optical detection device 30 or the camera system 32 are connected to a control device S only indicated here. If the position of the adhesive marker 2 has been detected by the optical detection device 30, 30 * or by the camera system 32, then the control device S possibly provides a rotating movement of the retaining mandrel 15, so that the adhesive marker 2 is thereby translated into a predetermined or defined nominal position. Position is brought. One in the explained below Figures 8 and 8A illustrated suction and / or gripping device 34 and a suction rod 34 * can then detect the free end portion 7 of the supply roll 5 and subtract. Subsequently, the flat and / or strip material 8 or the shrink film 9 of the supply roll 5 with a flat and / or strip material or a shrink film of the other supply roll 5 * are welded in a method not shown.
