Definitions
- the invention relates to a method of producing napkin-loaded pouches, wherein two web-shaped layers of a flat, flexible material are moved along a transport path and held apart in a portion of the transport path, napkins are separated from a stack and between the layers brought, in the web direction after the portion of the napkins adjacent portions of the layers are brought into contact and connected together and the pockets thus formed are separated from the web-like layers (see JP-A-10 316108 ).
- napkins is intended to include absorbent, flat, flexible structures including those with low rigidity, in particular folded and / or multi-layer structures of fiber-containing and / or textile material.
- bag is to be understood in the present context as meaning a flat sheath open in the region of at least one side edge.
- Bags stocked with napkins are enjoying increasing popularity. With them, especially in the hospitality industry tables can be covered faster and easier, the napkin must not be touched by the staff. Often the bags are also equipped with cutlery, which further simplifies the work of the table cover. Especially in the outdoor area, such as in garden or terrace restaurants, the bags have the further advantage that the napkin can not be blown by the wind from the table. In addition, the bags can be printed with decorative elements and / or colors and / or advertising.
- the document WO 1999/23984 A1 describes individually packaged absorbent articles and a method of making them.
- the absorbent articles such as underwear liners are completely enclosed in packaging material.
- the articles are brought between the layers in the web direction and the layers are joined together so that the articles are completely enclosed by the packaging material.
- Individual packaging units are finally separated from the web.
- the invention is based on the object to provide a method by which populated with napkins bags can be easily and inexpensively manufactured in large quantities, the napkins between the layers are accurately positioned.
- this solution has the advantage that pockets equipped with napkins are much simpler, faster and thus less expensive to produce than in known methods, wherein in particular the napkins are positioned precisely between the layers.
- the two web-shaped layers are formed by folding in the web direction from a single web of flat, flexible material. This offers advantages in handling because only one single web has to be fed. In addition, this saves a connection seam at the bottom of the pockets.
- Another embodiment provides that on the side from which the napkin is placed between the layers, the longitudinal edge of one layer is offset from the longitudinal edge of the other layer. This provides the opportunity to let the napkin stick out of the opening of the bag, but without overhanging the bag. As a result, the napkin is recognized by the guest immediately and can also be easily removed.
- the longitudinal edge of the other layer is folded over and the folded-over part projects below the longitudinal edge of the one layer.
- contour is meant that the longitudinal edge is not straight.
- the contour is directed in the respective area of a napkin against this, so that the napkin is even better visible and can be easily removed.
- incisions are present in the one layer at a distance from its longitudinal edge. These are used in the finished bag for inserting utensils, especially cutlery, which is then clearly visible on the napkin.
- the flat, flexible material is a film or paper, which is preferably provided at least in regions with a sealable layer.
- a sealable layer can be made of polyethylene, for example, which allows a connection of the layers by heat sealing.
- the napkins are aligned in the stack at least approximately parallel to at least one of the two sheet-like layers. Thus they can be brought in a movement parallel to their level on the slide mentioned below.
- the napkins in the stack are aligned at least approximately at right angles to at least one of the two web-shaped layers. This offers the possibility to bring the napkins by a pivotable separating element on the slide mentioned below.
- the napkins are separated from the stack by a movable, vacuum-applied separating element.
- the separation by means of vacuum is particularly well with less rigid napkins.
- a particular embodiment provides that the separating element is pivotable about 90 degrees.
- a pivotable separating element is particularly favorable in terms of mechanical complexity and ease of storage on the slide mentioned below.
- a napkin is deposited by the separating element on a reciprocable slider which brings the napkin between the layers in each case. Since napkins usually have a low bending stiffness, such a slide ensures trouble-free operation.
- the napkins are stored properly without having to control the vacuum by valves or the like.
- a further embodiment of the method provides that at least one empty pocket is formed in each case in the web direction adjacent to a pocket provided with a napkin and that in each case a group of pockets is separated from the web-shaped layers.
- the invention also relates to a device for producing napkin-loaded pockets, comprising means for transporting two web-shaped layers of a flat, flexible material in the web direction along a transport path, a spacer for spacing the layers in a region of the transport path at a distance from each other a napkin holder in which napkins are stored in a stack, singulating means for singulating the napkins from the stack, inserting means for inserting a napkin between the plies, means for contacting and patching the plies into pockets, and means for separating the pockets from the web-shaped layers, wherein the means for contacting and area-wise connecting the layers to pockets are arranged in the web direction after the introduction means.
- This aspect of the invention has for its object to propose a device with which With a napkin equipped bags can be easily, automatically and inexpensively produced in a large series, with the napkins are positioned exactly between the layers.
- the insertion means have a substantially oriented parallel to the web direction pad and in a direction oriented substantially at right angles to the web direction between a position in which the pad is located next to the layers and a position in which the support at least partially located between the layers, are movable back and forth.
- This solution has the considerable advantage that can be dispensed with the subsequent seizure or holding finished bags and spreading their opening for the introduction of a napkin and that in particular the napkins between the layers are accurately positioned.
- FIGS. 1 and 2 To illustrate an embodiment of the method according to the invention schematically show some components of a plant for producing each equipped with a napkin bags and the materials used and an example of an end product.
- a stored on a roll not shown, for example, one-side printed web is withdrawn from the roll and folded longitudinally, so that form two web-shaped layers 1 and 2.
- the two layers 1 and 2 could also be separate paper webs.
- the arrows 3 in Fig. 1 show the transport path of the layers 1, 2.
- the layers 1, 2 are guided substantially horizontally and the transport is preferably carried out intermittently.
- Folded napkins 5 are held in a stack in a napkin holder 6 in such a manner that the plane of the napkins is oriented substantially vertically approximately at right angles to the plane of the plies 1, 2 and the longitudinal axis of the napkins.
- Retaining plate 7 on the napkin holder 6 prevent the napkins 5 fall out of the holder 6.
- a pressing device 8 makes sure that the napkin stack always bears against the holding plate 7.
- the pressing device 8 is mounted on rollers and the bottom of the napkin holder 6 is slightly inclined to the layers 1, 2 out.
- a tapping device 9 for shaking the napkin holder 6 can be provided under the napkin holder 6, which in FIG Fig. 2 drawn in the form of a stylized piston-cylinder unit. Incidentally, care should be taken in this arrangement of the napkin holder 6 that the folded edge of the napkins 5 is in the holder above.
- a slider 10 is arranged, which is movable from the initial position shown in the figures in the direction of the double arrow 11 between the layers 1, 2 and back again.
- a vertically projecting from the slider 10 legs 12 is disposed on the side facing away from the layers 1, 2 of the slider 10 and on both sides of the slider 10 fixed side guides 14 are provided.
- a pivotable about a parallel to the transport direction of the layers 1, 2 pivot axis 16 is arranged suction tube 15 which is pivotable in the direction of the double arrow 17 by about 90 degrees back and forth .
- the suction tube 15, to which a vacuum is applied has two suction openings 18 and 19, with which the respective foremost napkin 5 of the stack is sucked in and deposited on the slider 10 after the pivoting movement of the suction tube 15.
- the suction tube 15 emerges during this pivoting movement through a slide 10 provided for this purpose longitudinal slot 13, wherein the path of the suction pipe 15 is dimensioned such that the suction openings 18 and 19 after placing the napkin 5 on the slider 10 is still a piece of remove the napkin 5.
- a control device and a valve for the vacuum applied to the suction pipe 15 is superfluous.
- the napkin 5 stored on the slider 10 is brought by the said movement of the slider 10 in the direction of the double arrow 11 between the layers 1 and 2 and left there upon retraction of the slider 10 there.
- a folded web of the space between the layers 1, 2 is wedge-shaped, so that the napkin 5 is easily clamped in the region of the bottom edge 24 and the napkin 5 is thereby not pulled back with the slide back out.
- the clamping force of the layers 1, 2 itself should be insufficient, which may be the case in particular when using two separate layers 1, 2, it is possible to provide a clamping device 20 for holding the napkin 5, which in FIG Fig. 2 drawn in the form of a stylized piston-cylinder unit.
- the layers 1, 2 are preferably stopped. So that during the gradual further transport of the layers 1, 2, the napkin 5, which has just been deposited between them, does not slip, the following measures can be provided.
- a pressure roller 21, which can be moved perpendicular to the layers 1, 2, can compress the layers during the subsequent transport step and thus hold the napkins 5 between the layers 1, 2.
- a sealing device can be arranged, which connects the layers 1, 2 between two napkins 5 at least temporarily together.
- these measures can be dispensed with, in particular when using a folded web and when the acceleration of the layers 1, 2 during further transport is not too great.
- the two layers 1, 2 are advantageously offset from each other, so that the napkin 5 always remains visible and can be easily removed for use.
- the upper layer 1 limiting opening edge 26 may have an arcuate contour, for example, as in Fig. 1 is apparent. Since the paper web used for the production of the bags is advantageously printed on one side, in the in Fig. 2 illustrated embodiment, the web at the opening side provided with a fold 25, so that in the finished pockets, the free end of the folded leg is covered by the upper layer 1. This is also particularly advantageous when using, for example, a polyethylene-coated paper which is weldable on the coated side but poorly printable.
- the layers 1, 2 are approximated to each other and connected to each other in the area between each two consecutive napkins 5.
- This is preferably done by known thermal sealing methods. Since these sealing methods themselves and the corresponding devices are not subject of the present patent application, is in Fig. 1 only the area in question is referred to as seal area 22.
- the sealing area 22 is made so wide that during the subsequent separation process a strip can be cut out of the layers and still leave a sealing edge at the side edges of the resulting pockets. Cutting out a strip, in Fig. 1 indicated by the separation region 23, is preferred because when printing the web in the rotary printing process, the entire circumference of the printing cylinder can not be utilized and the non-printed material strip is cut out of the web.
- FIG. 1 shows bags, as in Fig. 1 are shown below. Rather, multiple pockets can be produced with adjacent pockets that can be used, for example, as a placemat, as described below with reference to the Figures 3 and 4 is described.
- the representation according to Fig. 3 shows schematically the production of placemats, wherein the same reference numerals are used for the same parts as in the on hand of the FIGS. 1 and 2 described Embodiment.
- a single web with folded bottom edge 24 can also be used here.
- not every pocket is stocked with a napkin 5.
- the additional, unequipped pockets are in Fig. 3 designated by the reference numeral 30 and are wider than the respective napkin 5 containing pockets. Further, in this example, in the upper layer, in the region of each pocket containing a napkin 5, at a distance from the opening edge 26, there is an indentation 27, the purpose of which is described below with reference to FIG Fig. 4 illustrated embodiment will be explained.
- the opening edge 26 may be straight or as shown in FIG Fig. 1 be executed contoured.
- Fig. 4 an embodiment of a placemat 1 is shown in perspective. Subsequently, the placemat is described as it sees a person sitting at a table, that is, the person facing this edge is referred to as bottom edge 24 as in the examples described above. On the right edge 8 of the placemat 1 you can see a first bag 28 in which a folded napkin 5 is partially received, so that it protrudes upwards by a few inches and thus is clearly visible at first glance.
- the placemat typically has a width of about 40 centimeters and a height of about 25 centimeters. The height of the pockets measured from the bottom edge 24 of the set, for example, about 18 centimeters.
- the above-mentioned recess 27 is arranged in the first pocket, which may have a curved course as shown in the figure and is received in the cutlery 31, in particular a fork and a knife.
- both a napkin 5 and cutlery 31 are added to each other to save space in the first pocket and yet at least optically separated from each other by the upper part of the first pocket 28, which gives the whole an attractive appearance.
- a second pocket 29 and a third pocket 30 are arranged. All three pockets 28, 29 and 30 preferably have a common upper edge which corresponds to the aforementioned opening edge 26, and extend from this to the lower bottom edge 24 of the table set.
- the second pocket 29 is equipped with a window 32 through which a part of a in the Bag 29 existing object, such as a present on a menu 33 image 34 is visible.
- the window 32 may be provided with a cling film, for example.
- a drinks menu 35 may be inserted in the third pocket 30 adjacent to the left edge of the table set.
- connecting seams 36 and 37 are attached, which connect the material forming the pockets.
- the connecting seams do not have to run continuously from the bottom edge 24 of the table set to the opening edge 26 of the pockets, but can extend or be interrupted only over a part of this distance.
- the menu 33 and / or the drinks card 35 can be put into pockets between the layers 1, 2, like the napkin 5 in the manufacturing process prior to uniting the layers 1, 2, or subsequently inserted into the pockets 29, 30 of the finished placemats.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von mit einer Serviette bestückten Taschen, wobei zwei bahnförmige Lagen eines flachen, flexiblen Materials längs eines Transportweges bewegt und in einem Abschnitt des Transportweges in einem Abstand voneinander gehalten, Servietten ab einem Stapel vereinzelt und zwischen die Lagen gebracht, in Bahnrichtung nach dem Abschnitt den Servietten benachbarte Bereiche der Lagen miteinander in Kontakt gebracht und miteinander verbunden und die derart gebildeten Taschen von den bahnförmigen Lagen abgetrennt werden (siehe
Der Begriff Servietten soll dabei saugfähige, flächige, flexible Gebilde einschließlich solcher mit geringer Steifigkeit, insbesondere gefaltete und/oder mehrlagige Gebilde aus faserhaltigem und/oder textilem Material umfassen. Unter dem Ausdruck Tasche soll im vorliegenden Zusammenhang eine im Bereich mindestens einer Seitenkante offene, flache Umhüllung verstanden werden.The term napkins is intended to include absorbent, flat, flexible structures including those with low rigidity, in particular folded and / or multi-layer structures of fiber-containing and / or textile material. The term bag is to be understood in the present context as meaning a flat sheath open in the region of at least one side edge.
Mit Servietten bestückte Taschen erfreuen sich zunehmender Beliebtheit. Mit ihnen lassen sich insbesondere im Gastgewerbe Tische schneller und einfacher decken, wobei die Serviette vom Personal nicht berührt werden muss. Oft werden die Taschen zusätzlich mit Besteck bestückt, was die Arbeit des Tischdeckens weiter vereinfacht. Insbesondere im Außenbereich, wie beispielsweise in Garten- oder Terrassen-Gaststätten haben die Taschen den weiteren Vorteil, dass die Serviette nicht vom Wind vom Tisch geweht werden kann. Zudem lassen sich die Taschen mit dekorativen Elementen und/oder Farben und/oder Werbung bedrucken.Bags stocked with napkins are enjoying increasing popularity. With them, especially in the hospitality industry tables can be covered faster and easier, the napkin must not be touched by the staff. Often the bags are also equipped with cutlery, which further simplifies the work of the table cover. Especially in the outdoor area, such as in garden or terrace restaurants, the bags have the further advantage that the napkin can not be blown by the wind from the table. In addition, the bags can be printed with decorative elements and / or colors and / or advertising.
Es ist bekannt, zuerst Taschen herzustellen und diese danach mit jeweils einer Serviette zu bestücken. Dieser Vorgang des Bestückens ist aufwändig, weil jede Tasche einzeln erfasst, ihre Öffnung gespreizt und dann eine Serviette, meist durch Schwerkraft, eingeführt werden muss. Durch dieses arbeitsintensive Befüllen wird das Endprodukt relativ teuer und verliert dadurch teilweise seine Attraktivität.It is known to first make bags and then to equip each with a napkin. This process of assembly is complex, because each pocket seized individually, spread their opening and then a napkin, usually by gravity, must be introduced. This labor-intensive filling makes the end product relatively expensive, thereby partially losing its appeal.

Aus der Patentanmeldung
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren vorzuschlagen, mit dem mit Servietten bestückte Taschen einfach und kostengünstig in große Stückzahlen hergestellt werden können, wobei die Servietten zwischen den Lagen exakt positioniert werden.The invention is based on the object to provide a method by which populated with napkins bags can be easily and inexpensively manufactured in large quantities, the napkins between the layers are accurately positioned.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in dem Abschnitt jeweils eine Serviette in einer im Wesentlichen parallel zur Bahnrichtung orientierten Lage in einer im Wesentlichen rechtwinklig zur Bahnrichtung orientierten Bewegungsrichtung zwischen die Lagen gebracht wird.This object is achieved in that in each case a napkin is placed in a substantially oriented parallel to the web direction position in a direction oriented substantially perpendicular to the web direction of movement between the layers.
Diese Lösung hat insbesondere den Vorteil, dass mit Servietten bestückte Taschen viel einfacher, schneller und dadurch kostengünstiger herstellbar sind als bei bekannten Verfahren, wobei insbesondere die Servietten zwischen den Lagen exakt positioniert werden.In particular, this solution has the advantage that pockets equipped with napkins are much simpler, faster and thus less expensive to produce than in known methods, wherein in particular the napkins are positioned precisely between the layers.
Nach einer Ausführungsart werden die beiden bahnförmigen Lagen durch Umfalten in Bahnrichtung aus einer einzigen Bahn des flachen, flexiblen Materials gebildet. Dies bietet Vorteile im Handling, weil nur eine einzige Bahn zugeführt werden muss. Darüber hinaus wird dadurch eine Verbindungsnaht am Boden der Taschen eingespart.According to one embodiment, the two web-shaped layers are formed by folding in the web direction from a single web of flat, flexible material. This offers advantages in handling because only one single web has to be fed. In addition, this saves a connection seam at the bottom of the pockets.
Eine andere Ausführungsart sieht vor, dass an der Seite, von der die Serviette zwischen die Lagen gebracht wird, der Längsrand der einen Lage gegenüber dem Längsrand der anderen Lage zurück versetzt wird. Dies bietet die Möglichkeit, die Serviette aus der Öffnung der Tasche heraus ragen zu lassen, ohne jedoch die Tasche zu überragen. Dadurch wird später die Serviette vom Gast sofort erkannt und kann zudem leicht entnommen werden.Another embodiment provides that on the side from which the napkin is placed between the layers, the longitudinal edge of one layer is offset from the longitudinal edge of the other layer. This provides the opportunity to let the napkin stick out of the opening of the bag, but without overhanging the bag. As a result, the napkin is recognized by the guest immediately and can also be easily removed.
Nach einer weiteren Ausführungsart wird der Längsrand der anderen Lage umgefaltet und der umgefaltete Teil ragt unter den Längsrand der einen Lage. Auf diese Weise entsteht aus einer einseitig bedruckten Bahn eine allseits bedruckte Tasche, weil die unbedruckte Seite vollständig im Inneren der Tasche verborgen wird.According to a further embodiment, the longitudinal edge of the other layer is folded over and the folded-over part projects below the longitudinal edge of the one layer. In this way, from a one-sided printed web creates a well-printed bag, because the unprinted side is completely hidden inside the bag.
Noch eine Ausführungsart zeichnet sich dadurch aus, dass der Längsrand der einen Lage eine Kontur aufweist. Mit Kontur ist dabei gemeint, dass der Längsrand nicht gerade verläuft. Vorzugsweise ist dabei die Kontur im jeweils Bereich einer Serviette gegen diese gerichtet, so dass die Serviette noch besser sichtbar wird und noch leichter entnommen werden kann.Another embodiment is characterized in that the longitudinal edge of the one layer has a contour. By contour is meant that the longitudinal edge is not straight. Preferably, the contour is directed in the respective area of a napkin against this, so that the napkin is even better visible and can be easily removed.
Nach einer weiteren Ausführungsart sind in der einen Lage in einem Abstand von deren Längsrand Einschnitte vorhanden. Diese dienen bei der fertigen Tasche zum Einstecken von Utensilien, insbesondere Besteck, das dann gut sichtbar über der Serviette liegt.According to another embodiment, incisions are present in the one layer at a distance from its longitudinal edge. These are used in the finished bag for inserting utensils, especially cutlery, which is then clearly visible on the napkin.
Gemäß weiteren Ausführungsarten ist das flache, flexible Material eine Folie oder Papier, welches vorzugsweise mindestens bereichsweise mit einer siegelfähigen Schicht versehen ist. Eine solche Schicht kann beispielsweise aus Polyethylen sein, welches eine Verbindung der Lagen durch Heißsiegeln erlaubt.According to further embodiments, the flat, flexible material is a film or paper, which is preferably provided at least in regions with a sealable layer. Such a layer can be made of polyethylene, for example, which allows a connection of the layers by heat sealing.
Nach einer Ausführungsart sind die Servietten im Stapel mindestens annähernd parallel zu mindestens einer der zwei bahnförmigen Lagen ausgerichtet. So lassen sie sich in einer Bewegung parallel zu ihrer Ebene auf den weiter unten erwähnten Schieber bringen.According to one embodiment, the napkins are aligned in the stack at least approximately parallel to at least one of the two sheet-like layers. Thus they can be brought in a movement parallel to their level on the slide mentioned below.
Alternativ zur vorangehend erwähnten Ausführungsart sind die Servietten im Stapel mindestens annähernd rechtwinklig zu mindestens einer der zwei bahnförmigen Lagen ausgerichtet. Dies bietet die Möglichkeit, die Servietten durch ein schwenkbares Vereinzelungselement auf den nachstehend erwähnten Schieber zu bringen.As an alternative to the above-mentioned embodiment, the napkins in the stack are aligned at least approximately at right angles to at least one of the two web-shaped layers. This offers the possibility to bring the napkins by a pivotable separating element on the slide mentioned below.
Nach einer Ausführungsart des Verfahrens werden die Servietten vom Stapel durch ein bewegliches, mit Vakuum beaufschlagtes Vereinzelungselement vereinzelt. Die Vereinzelung mittels Vakuum eignet sich bei wenig biegesteifen Servietten besonders gut.According to one embodiment of the method, the napkins are separated from the stack by a movable, vacuum-applied separating element. The separation by means of vacuum is particularly well with less rigid napkins.
Eine besondere Ausführungsart sieht vor, dass das Vereinzelungselement um etwa 90 Grad schwenkbar ist. Ein schwenkbares Vereinzelungselement ist hinsichtlich des mechanischen Aufwandes und der einfachen Ablage auf dem nachstehend erwähnten Schieber besonders günstig.A particular embodiment provides that the separating element is pivotable about 90 degrees. A pivotable separating element is particularly favorable in terms of mechanical complexity and ease of storage on the slide mentioned below.
Gemäß einer zusätzlichen Ausführungsart wird jeweils eine Serviette durch das Vereinzelungselement auf einem hin- und her bewegbaren Schieber abgelegt, der die Serviette zwischen die Lagen bringt. Da Servietten in der Regel eine geringe Biegesteifigkeit haben, sichert sich ein solcher Schieber einen störungsfreien Betrieb.According to an additional embodiment, a napkin is deposited by the separating element on a reciprocable slider which brings the napkin between the layers in each case. Since napkins usually have a low bending stiffness, such a slide ensures trouble-free operation.
Wenn nach einer weiteren Ausführungsart im Schieber eine Aussparung vorhanden ist, durch welche sich das Vereinzelungselement beim Ablegen einer Serviette hindurch bewegt und das Vereinzelungselement dauernd mit Vakuum beaufschlagt ist, werden die Servietten einwandfrei abgelegt, ohne dass das Vakuum durch Ventile oder dergleichen gesteuert werden muss.If, according to a further embodiment, there is a recess in the slide through which the separating element moves when depositing a napkin and the separating element is permanently exposed to vacuum, the napkins are stored properly without having to control the vacuum by valves or the like.
Schließlich sieht eine weitere Ausführungsart des Verfahrens vor, dass jeweils in Bahnrichtung benachbart zu einer mit einer Serviette bestückten Tasche mindestens eine leere Tasche gebildet wird und dass jeweils eine Gruppe von Taschen von den bahnförmigen Lagen abgetrennt wird. Dadurch lassen sich vielfach verwendbare Taschen-Kombinationen herstellen, die besonders bevorzugt als Tischset Verwendung finden.Finally, a further embodiment of the method provides that at least one empty pocket is formed in each case in the web direction adjacent to a pocket provided with a napkin and that in each case a group of pockets is separated from the web-shaped layers. As a result, multipurpose pocket combinations can be produced which are particularly preferably used as placemat.
Die Erfindung betrifft auch eine Vorrichtung zum Herstellen von mit einer Serviette bestückten Taschen, enthaltend Mittel zum Transportieren von zwei bahnförmige Lagen eines flachen, flexiblen Materials in Bahnrichtung längs eines Transportweges, einen Abstandhalter, um die Lagen in einem Bereich des Transportweges in einem Abstand voneinander zu halten, eine Serviettenhalterung, in der Servietten in einem Stapel gelagert sind, eine Vereinzelungseinrichtung zum Vereinzeln der Servietten vom Stapel, Einbringmittelmittel zum Einbringen jeweils einer Serviette zwischen die Lagen, Mittel zum Kontaktieren und bereichsweisen Verbinden der Lagen zu Taschen und Mittel zum Abtrennen der Taschen von den bahnförmigen Lagen, wobei die Mittel zum Kontaktieren und bereichsweisen Verbinden der Lagen zu Taschen in Bahnrichtung nach den Einbringmitteln angeordnet sind.The invention also relates to a device for producing napkin-loaded pockets, comprising means for transporting two web-shaped layers of a flat, flexible material in the web direction along a transport path, a spacer for spacing the layers in a region of the transport path at a distance from each other a napkin holder in which napkins are stored in a stack, singulating means for singulating the napkins from the stack, inserting means for inserting a napkin between the plies, means for contacting and patching the plies into pockets, and means for separating the pockets from the web-shaped layers, wherein the means for contacting and area-wise connecting the layers to pockets are arranged in the web direction after the introduction means.
Dieser Aspekt der Erfindung hat zur Aufgabe, eine Vorrichtung vorzuschlagen, mit der sich mit einer Serviette bestückte Taschen einfach, automatisch und kostengünstig in großer Serie herstellen lassen, wobei die Servietten zwischen den Lagen exakt positioniert werden.This aspect of the invention has for its object to propose a device with which With a napkin equipped bags can be easily, automatically and inexpensively produced in a large series, with the napkins are positioned exactly between the layers.
Die Aufgabe wird dadurch gelöst, dass die Einbringmittel eine im Wesentlichen parallel zur Bahnrichtung orientierten Auflage aufweisen und in einer im Wesentlichen rechtwinklig zur Bahnrichtung orientierten Richtung zwischen einer Position, in der sich die Auflage neben den Lagen befindet und einer Position, in der sich die Auflage mindestens teilweise zwischen den Lagen befindet, hin und her bewegbar sind.The object is achieved in that the insertion means have a substantially oriented parallel to the web direction pad and in a direction oriented substantially at right angles to the web direction between a position in which the pad is located next to the layers and a position in which the support at least partially located between the layers, are movable back and forth.
Diese Lösung bringt den erheblichen Vorteil mit sich, dass auf das nachträgliche Ergreifen oder Halten fertiger Taschen und Spreizen ihrer Öffnung zum Einführen einer Serviette verzichtet werden kann und dass insbesondere die Servietten zwischen den Lagen exakt positioniert werden.This solution has the considerable advantage that can be dispensed with the subsequent seizure or holding finished bags and spreading their opening for the introduction of a napkin and that in particular the napkins between the layers are accurately positioned.

Einführend sei festgehalten, dass in den unterschiedlich beschriebenen Ausführungsformen gleiche Teile mit gleichen Bezugszeichen bzw. gleichen Bauteilbezeichnungen versehen werden, wobei die in der gesamten Beschreibung enthaltenen Offenbarungen sinngemäß auf gleiche Teile mit gleichen Bezugszeichen bzw. gleichen Bauteilbezeichnungen übertragen werden können. Auch sind die in der Beschreibung gewählten Lageangaben, wie z.B. oben, unten, seitlich usw. auf die unmittelbar beschriebene sowie dargestellte Figur bezogen und sind bei einer Lageänderung sinngemäß auf die neue Lage zu übertragen.By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information selected in the description, such as above, below, laterally, etc. related to the immediately described and illustrated figure and are to be transferred to a new position in a change in position.
Die
Zwischen der Serviettenhalterung 6 und den Lagen 1, 2 ist ein Schieber 10 angeordnet, der von der in den Figuren dargestellten Ausgangslage in Richtung des Doppelpfeils 11 zwischen die Lagen 1, 2 und wieder zurück bewegbar ist. Zur Führung jeweils einer Serviette 5, die in noch zu beschreibender Weise auf dem Schieber 10 gelangt, ist an der von den Lagen 1, 2 abgewandten Seite des Schiebers 10 ein vertikal vom Schieber 10 abragenden Schenkel 12 angeordnet und beiderseits des Schiebers 10 sind ortsfeste Seitenführungen 14 vorgesehen.Between the
Zum Vereinzeln der Servietten 5 und Ablegen jeweils einer Serviette 5 auf dem Schieber 10 ist ein um eine parallel zur Transportrichtung der Lagen 1, 2 angeordnete Schwenkachse 16 schwenkbares Saugrohr 15 angeordnet, das in Richtung des Doppelpfeils 17 um etwa 90 Grad hin und her schwenkbar ist. Das Saugrohr 15, an dem ein Vakuum angelegt wird, weist zwei Saugöffnungen 18 und 19 auf, mit denen jeweils die vorderste Serviette 5 des Stapels angesaugt und nach der Schwenkbewegung des Saugrohrs 15 auf dem Schieber 10 abgelegt wird. Das Saugrohr 15 taucht bei dieser Schwenkbewegung durch einen im Schieber 10 zu diesem Zweck vorgesehenen Längsschlitz 13, wobei der Weg des Saugrohrs 15 derart bemessen ist, dass sich die Saugöffnungen 18 und 19 nach dem Ablegen der Serviette 5 auf dem Schieber 10 noch ein Stück von der Serviette 5 entfernen. Auf diese Weise wird eine Steuervorrichtung und ein Ventil für das am Saugrohr 15 angelegte Vakuum überflüssig.For separating the
Die auf dem Schieber 10 abgelegte Serviette 5 wird durch die genannte Bewegung des Schiebers 10 in Richtung des Doppelpfeils 11 zwischen die Lagen 1 und 2 gebracht und beim Zurückziehen des Schiebers 10 dort zurückgelassen. Bei der Verwendung einer gefalteten Bahn ist der Zwischenraum zwischen den Lagen 1, 2 keilförmig, so dass die Serviette 5 im Bereich der Bodenkante 24 leicht geklemmt wird und die Serviette 5 dadurch nicht mit dem zurück fahrenden Schieber wieder heraus gezogen wird. Falls die Klemmkraft der Lagen 1, 2 selbst ungenügend sein sollte, was insbesondere bei der Verwendung von zwei separaten Lagen 1, 2 der Fall sein kann, ist es möglich, zum Festhalten der Serviette 5 eine Klemmvorrichtung 20 vorzusehen, die in
Während des Einschiebens der Serviette 5 werden die Lagen 1, 2 vorzugsweise angehalten. Damit beim schrittweisen Weitertransport der Lagen 1, 2 die gerade zwischen ihnen abgelegte Serviette 5 nicht verrutscht, können folgende Maßnahmen vorgesehen werden. Eine senkrecht zu den Lagen 1, 2 bewegbare Andruckrolle 21 kann die Lagen während des nachfolgenden Transportschritts zusammendrücken und damit die Servietten 5 zwischen den Lagen 1, 2 festhalten. An Stelle der Andruckrolle 21 kann auch eine Siegelvorrichtung angeordnet werden, welche die Lagen 1, 2 zwischen zwei Servietten 5 zumindest provisorisch miteinander verbindet. In der Regel kann aber auf diese Maßnahmen verzichtet werden, insbesondere bei der Verwendung einer gefalteten Bahn und wenn die Beschleunigung der Lagen 1, 2 beim Weitertransport nicht zu groß ist.During the insertion of the
An der Öffnungsseite der Tasche werden die beiden Lagen 1, 2 vorteilhaft gegeneinander versetzt, damit die Serviette 5 immer sichtbar bleibt und zum Gebrauch leicht entnommen werden kann. Zusätzlich kann die die obere Lage 1 begrenzende Öffnungskante 26 eine beispielsweise bogenförmige Kontur aufweisen, wie dies in
Nach dem Einschieben der Serviette 5 werden die Lagen 1, 2 einander angenähert und im Bereich zwischen jeweils zwei nacheinander folgenden Servietten 5 miteinander verbunden. Dies geschieht vorzugsweise durch bekannte thermische Siegelverfahren. Da diese Siegelverfahren selbst und die entsprechenden Vorrichtungen nicht Gegenstand der vorliegenden Patentanmeldung sind, ist in
Mit dem erfindungsgemäßen Verfahren lassen sich nicht nur Taschen herstellen, wie sie in

Die Speisekarte 33 und/oder die Getränkekarte 35 können übrigens wie die Serviette 5 im Herstellungsverfahren vor dem Vereinigen der Lagen 1, 2 zu Taschen zwischen die Lagen 1, 2 gebracht oder nachträglich in die Taschen 29, 30 des fertigen Tischsets gesteckt werden.Incidentally, the
Der Ordnung halber sei abschließend darauf hingewiesen, dass zum besseren Verständnis des Aufbaus der Vorrichtung, der Tasche und des Tischsets diese bzw. deren Bestandteile teilweise unmaßstäblich und/oder vergrößert und/oder verkleinert dargestellt wurden.For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the device, the bag and the placemats, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
