Abstract

Pour pouvoir bobiner ensemble les articles individuels (9), tels que les sacs d'ordures en matière synthétique, une bande sans fin (1) amène les articles dans un plan d'alimentation (8) à la bobine (19). La bande sans fin (1) entoure la majeure partie de la périphérie de la bobine (19) pour garantir un bobinage convenable. La bande sans fin (1) et la bobine (19) sont entraînées par une poulie (33). Indépendamment du rayon momentané de la bobine, les rapports entre bobine (19) et poulie (33) restent constants dans le plan d'alimentation (8) et dans la zone d'alimentation (11). Des pivots (41) pénétrant latéralement maintiennent la bande sans fin (1) au diamètre d'enroulement minimal initial lorsqu'on commence une nouvelle bobine. Le premier article (9) est bobiné autour de cet enroulement. L'axe de bobinage avançant vers le haut est fixé (A) par le bobinage du premier article. Le bobinage s'effectue avec ou sans noyau de bobinage.In order to be able to wind individual articles (9), such as plastic garbage bags, together, an endless belt (1) feeds the articles in a feed plane (8) to the bobbin (19). The endless belt (1) surrounds most of the periphery of the spool (19) to ensure proper winding. The endless belt (1) and the spool (19) are driven by a pulley (33). Independently of the momentary radius of the coil, the relationships between coil (19) and pulley (33) remain constant in the feed plane (8) and in the feed zone (11). Laterally penetrating pivots (41) maintain the endless belt (1) at the initial minimum winding diameter when starting a new reel. The first article (9) is wound around this winding. The winding axis advancing upwards is fixed (A) by the winding of the first article. Winding is carried out with or without a winding core.

Description

Verfahren zum gemeinsamen Wickeln von Stückgütern aus flexiblem Material und Vorrichtung hierzu Process for the common winding of piece goods made of flexible material and device therefor
Die vorliegende Erfindung betrifft ein Verfahren zum gemeinsamen Wickeln von Stückgütern aus flexiblem Material um eine Wickelachse, bei dem man den Wickel auf einem Grossteil seines Umfangs mittels mindestens eines endlos umlaufenden Bandes umschlauft, und das Stückgut auf einer durch das Band gebildeten Zuführ¬ bahn, in einer Zuspeiseebene unmittelbar vor dem Wik- kel, letzterem zuspeist sowie eine Vorrichtung zum gemeinsamen Wickeln von Stückgütern aus flexiblem Material um eine Wickelachse mit einer den Wickel auf einem Grossteil seines Umfanges umschlingenden, umlaufenden Endlosbandanordnung, auf welcher das Stück¬ gut dem Wickel, entlang einer Zuspeiseebene, zugespie- sen wird.The present invention relates to a method for the common winding of piece goods made of flexible material around a winding axis, in which the loop is looped over a large part of its circumference by means of at least one endless belt, and the piece goods on a feed path formed by the belt, in a feed level directly in front of the winding, feeds the latter as well as a device for the common winding of piece goods made of flexible material around a winding axis with a continuous endless belt arrangement that wraps around the roll on a large part of its circumference, on which the piece feeds the roll along a Feed level, is fed.
Ein derartiges Verfahren ist aus der FR-PS 1 207 049 bekannt. Gemäss dieser Schrift wird zum gemeinsamen Wickeln von Stückgütern aus flexiblem Material ein endlos umlaufendes Band vorgesehen, welches einen Wickel während der Bildung zu einem Grossteil umschlauft. Das endlos umlaufende Band dient dabei gleichzeitig der Zuführung des Stückgutes zum Wickel hin, entlang einer Zuführbahn. Die Zuführbahn ist durch Umlenkrol¬ len gegeben und geht in eine Zuspeiseebene unmittelbar vor Eintritt in den Wickelbereich über. In einer Aus¬ führungsvariante des dann dargestellten Verfahrens wirkt eine Anpressrolle mit dem Wickel zusammen, wo¬ bei die Zuspeiseebene der Zuführbahn zwischen Wickel und Anpressrolle durchläuft. Die Achse des Wickels ist zur Aufnahme des sich zunehmend vergrössernden Wik- kelradius verschieblich gelagert. Bei unabhängig vom Wickelradius in ihrer Lage konstant geführter Zuspeise¬ ebene, unmittelbar vor dem Wickel und sich verändern- dem Wickelradius, verändert sich auch der Winkel, unter welchem die Zuspeiseebene dem Wickel zuläuft, d.h. der Winkel zwischen der Zuspeiseebene und einer Ebene, gebildet durch die Wickelachse und diejenige WickeImantellinie, an welcher die Zuspeiseebene die Wickelperipherie berührt bzw. schneidet. Dadurch wer¬ den mit zunehmendem Wickelradius die Einlaufverhält¬ nisse von Zuspeiseebene zum Wickel laufend verändert: Besagte Ebene ist nur in einem bestimmten Wickelradius Wickeltangentialebene. Für das Wickeln hochflexiblen Materials, wie von Kunststoffolie, ist dies ausser- ordentlich nachteilig, denn gerade die Einlaufzone an den Wickel ist für eine kontinuierliche, reibungs¬ lose Stückguteinrollung von wesentlicher Bedeutung.Such a method is known from FR-PS 1 207 049. According to this document, an endless circulating belt is provided for the common winding of piece goods made of flexible material, which wraps around a roll to a large extent during formation. The endlessly circulating belt also serves to feed the piece goods to the winding, along a feed path. The feed path is provided by deflecting rollers and merges into a feed level immediately before entering the winding area. In an embodiment variant of the method then presented, a pressure roller interacts with the winding, the feed plane of the feed path passing between the winding and pressure roller. The axis of the wrap is slidably supported to accommodate the increasingly increasing radius of the coil. If the position of the feed plane is constant, regardless of the winding radius, directly in front of the winding and changing winding radius, the angle at which the feeding plane approaches the winding also changes, ie the angle between the feeding plane and a plane formed by the winding axis and the WickeImantellinie at which the feed level touches or intersects the winding periphery. As a result, as the winding radius increases, the run-in conditions from the feed level to the winding are continuously changed: said level is only in a certain winding radius at the winding tangential level. This is extremely disadvantageous for the winding of highly flexible material, such as plastic film, because the run-in zone on the roll is of particular importance for a continuous, smooth piece goods rolling.
in einer zweiten Ausführungsvariante gemäss dieser Schrift wird wohl sichergestellt, dass, unabhängig von der Radiusänderung des Wickels, die Zuführebene immer Tagentialebene an den Wickel bleibt. Hingegen wird hierzu die Stückgutzuführbahn unmittelbar vor Eintreten in den Wickelbereich nach Massgabe des mo¬ mentanen Wickelradius mehr oder weniger umgelenkt, d.h. die Neigung der Zuspeiseebene verändert, was wiederum, insbesondere unmittelbar am Wickeleinlass, zu Problemen in der Zuführung und Einrollung sich folgender Stückgüter führt. 'In a second embodiment variant according to this document, it is probably ensured that, regardless of the change in radius of the roll, the feed plane always remains at the tag plane on the roll. On the other hand, the piece goods feed path is deflected more or less immediately before entering the winding area in accordance with the current winding radius, i.e. The inclination of the feed level changes, which in turn leads to problems in the feeding and curling of the following piece goods, especially directly at the winding inlet. '
Die vorliegende Erfindung setzt sich nun zum Ziel, ein Verfahren eingangs genannter Art zu schaffen,The present invention now aims to provide a method of the type mentioned at the outset,
OMPI bei welchem konstant definierte Einlaufverhältnisse für die Stückgüter unabhängig vom momentanen Wickel¬ radius gegeben sind.OMPI at which there are constantly defined run-in conditions for the piece goods regardless of the current winding radius.
Dies wird dadurch erreicht, dass man die Stückzuspei¬ seebene unabhängig vom Wickelradius lage-konstant hält und tangential an dem Wickel führt.This is achieved by keeping the piece feed plane constant in position, irrespective of the winding radius, and guiding it tangentially to the winding.
In einer AusführungsVariante,, bei der man das Band auf bekannte Art und Weise mittels einer Antriebsrol¬ lenanordnung treibt und mit dem Band auch den Wickel, wird die Antriebsrollenanordnung so ausgelegt, dass" eine Verbindungsebene von Rollenanordnungsachse und Wickelachse wickelradius-unabhängig- mit der Zuspeise- ebene wenigstens nahezu einen rechten Winkel bildet," vorzugsweise exakt.In an embodiment variant, in which the belt is driven in a known manner by means of a drive roller arrangement and with the belt also the winding, the drive roller arrangement is designed in such a way that " a plane of connection of the roller arrangement axis and the winding axis is independent of the winding radius - with the feed - plane forms at least almost a right angle, " preferably exactly.
Ein weiteres Problem, das sich im Zusammenhang mit obgenanntem Verfahren stellt, ist, dass herkömmlicher- weise derartige Wickel entweder auf Wickelkernen, die' in den Wickeln verbleiben oder daraus ausgezogen werden, oder- mittels" seitlicher Greifdornen gewickelt werden, welch letztere ein erstes Stückgut eines z bildenden Wickels frontseitig erfassen und einrollen. Solche Kerne' oder Dornen sind" zusätzliche Organe, die entwe¬ der als im Wickel verbleibendes Verbrauchsmaterial deren" Kosten steigern oder die, gesteuert beweglich, in den Wickelprozess eingreifen." Letzteres ergibt einen höheren" Maschinenherstellungsaufwand und ist eine zusätzliche Fehlerquelle"." Gerade bei derAnother problem that arises in connection with the above-mentioned method is that conventionally such windings are wound either on winding cores which remain in the windings or are pulled out of them, or by means of "lateral gripping mandrels, the latter being a first piece good Such cores or thorns are "additional organs that either increase their " costs as consumables remaining in the winding or that, in a controlled manner, intervene in the winding process in a controlled manner. " The latter results in a higher " machine production effort and is an additional source of error " . " Especially with the
O PI Grundsatz verfolgt werden, dass möglichst wenig Or¬ gane während des Prozesses auf die Stückgüter ein¬ greifen sollen , jeder derartige Eingriff bildet eine mögliche Störquelle. Um nun diese Problematik zu be- heben, wird in einem Ausführungsbeispiel des genann¬ ten Verfahrensvorgeschlagen, dass man die Achse des Wickels durch Vorgabe einer Initial-Minimalbandum- schlingung festlegt. Durch eine solche Vorgabe einer kleinen vorgegebenen Umschlingungsschlaufe wird das erste Stückgut eines zu erstellenden Wickels ohne Zusatzorgane entsprechend der kleinen Umschlingung eingerollt und diese eingerollte Partie bildet für nächstfolgende Stückgüter die Wickelachse.O PI The principle to be followed is that as few organs as possible should intervene in the piece goods during the process, each such intervention constitutes a possible source of interference. In order to remedy this problem, it is proposed in one exemplary embodiment of the above-mentioned method that the axis of the winding is determined by specifying an initial minimum band wrap. By specifying a small predetermined looping loop in this way, the first piece goods of a roll to be created are rolled up without additional organs in accordance with the small looping and this rolled-up part forms the winding axis for the next piece goods.
Eine Vorrichtung zum gemeinsamen Wickeln von Stück¬ gütern aus wickelbar flexiblem Material um eine Wickelachse mit einer den Wickel auf einem Grossteil seines Umfanges umschlingenden, umlaufenden, Endlos¬ bandanordnung, auf welcher das Stückgut dem Wickel auf einer Zuspeiseebene zugespiesen wird, zeichnet sich zur Lösung der genannten Aufgaben dadurch aus, dass die Zuspeiseebene in ihrer Lage bis zur Wickel¬ berührung unabhängig vom Wickelradius ist und tan- gential an den Wickel läuft.A device for the common winding of piece goods made of flexible material that can be wound around a winding axis with an endless belt arrangement that wraps around the roll on a large part of its circumference and on which the piece goods are fed to the roll on a feed level, is a solution to the problem mentioned tasks characterized in that the feed level is independent of the winding radius in its position up to the winding contact and runs tangentially to the winding.
Ist eine Antriebsrollenanordnung für die Bandanord¬ nung vorgesehen, so stehen die Zuspeiseebene und eine Verbindungsebene zwischen Wickelachse und Antriebs- rollenanordnungs-Achse mindestens nahezu, vorzugswei- se genau, senkrecht aufeinander. In einer Ausbildung der Vorrichtung zum kern- und dornlosen Wickeln wird weiter vorgeschlagen, dass die Wickelachse durch eine vorgegebene Initial-Minimalumschlingung der Bandan¬ ordnung gegeben ist. Um dies auf einfache Art und Weise zu realisieren, wird die Bandanordnung den Wickel mindestens einseitig überragend ausgebildet und es wird mindestens auf dieser Seite eine Zapfen¬ anordnung, gegen den Wickel einragend, vorgesehen, um, ohne Wickel, die Initial-Minimalumschlingung festzulegen.If a drive roller arrangement is provided for the belt arrangement, the feed plane and a connection plane between the winding axis and the drive roller arrangement axis are at least almost, preferably exactly, perpendicular to one another. In an embodiment of the device for coreless and mandrel-less winding, it is further proposed that the winding axis be replaced by a predetermined initial minimum wrap of the band arrangement is given. In order to achieve this in a simple manner, the belt arrangement is designed to protrude at least on one side of the winding and a pin arrangement is provided at least on this side, projecting against the winding, in order to fix the initial minimum wrap without a winding.
Weitere erfinderische Merkmale des Verfahrens und der Vorrichtung werden aus der nachfolgenden Be¬ schreibung ersichtlich, die sich auf Figuren stützt, die beispielsweise die Erfindung darlegen.Further inventive features of the method and the device can be seen from the following description, which is based on figures which, for example, explain the invention.

In Fig. 1 ist ein Endlosband 1 dargestellt, das um stationär gelagerte Umlenkrollen 3 sowie um mittels eines schematisch dargestellten Kipp-Mechanismus 5 hochschwenkbare Führungsrollen 7 umläuft. In Pfeil¬ richtung fortschreitend, geht das Endlosband 1 in eine Zuspeiseebene 8 über, worauf die zu wickelnden Stückgüter 9 aufgebracht werden. Die Zuspeiseebene 8 läuft mit den Stückgütern 9 in einen Wickeleinlass¬ bereich 11 ein. Zur Bildung des Wickels ist bei die- sem Ausführungsbeispiel ein Kern 13 oder ein Paar darunter gestrichelt eingetragene seitliche Greif¬ dorne 15 vorgesehen. Ein erstes Stückgut eines zu bildenden Wickels wird entweder über den Kern 13 ein¬ gerollt oder seitlich von den Greifdornen 15 ergrif- fen und ebenfalls eingerollt. Das Endlosband 1 geht nach Bildung der Zuspeiseebene 8 in einen Umschlin¬ gungsbereich 17 über und umschlingt auf einem Gross¬ teil des sich verändernden Umfanges den Wickel 19 mit den sukzessiv aufgewickelten Stückgütern 9. Hat der Umschlingungsbereich 17 des Endlosbandes 1 nahezu den Wickeleinlassbereich 11 wieder erreicht, so wird das Endlosband 1 scharfwinklig vom Wickel abgehoben, mit Hilfe einer relativ dünnen Umlenkachse 21 , die mit Hilfe einer Feder 23 gegen den momentanen Mantel des Wickels 19 angepresst wird. Die Feder 23 ist da¬ bei mitsamt der Umlenkachse 21 derart geführt, z.B. parallel zur Zuspeiseebene 8, dass die Achse 21 nie mit dem Stückgut 9 in Berührung kommt. Bei der Um¬ lenkachse 21 kann es sich um eine drehbar abgestützte Achse handeln oder um einen Umlenkstab aus geeignetem Material, um Reibungsverluste und Verschleisserschei- nungen möglichst gering zu halten, wie aus Teflon, wobei die Anordnung der Federn 23 in entsprechenden, gegenlagerbildenden Büchsen 25 beidseits der Umlenk- achse 21 vorgesehen ist. Die Anordnung der Büchsen 25 mit den Federn 23 sowie der Umlenkachse 21 ist, wie dargestellt, ebenfalls mit dem KippmechanismusIn Fig. 1, an endless belt 1 is shown, which rotates around stationary guide pulleys 3 and 5 by means of a schematically illustrated tilt mechanism 5 pivotable guide rollers 7. Continuing in the direction of the arrow, the endless belt 1 goes in a feed level 8 over which the piece goods 9 to be wound are applied. The feed level 8 runs with the piece goods 9 into a winding inlet area 11. In this exemplary embodiment, a core 13 or a pair of lateral gripping spikes 15 shown in dashed lines below are provided to form the winding. A first piece good of a roll to be formed is either rolled over the core 13 or gripped laterally by the gripping mandrels 15 and also rolled up. After formation of the feed level 8, the endless belt 1 merges into a wrapping area 17 and wraps the winding 19 with the successively wound piece goods 9 over a large part of the changing circumference. The wrapping area 17 of the endless belt 1 has almost reached the winding inlet area 11 again , the endless belt 1 is lifted off the winding at a sharp angle, with the aid of a relatively thin deflection axis 21, which is pressed against the current jacket of the winding 19 with the aid of a spring 23. The spring 23 is guided together with the deflection axis 21 in such a way, for example parallel to the feed plane 8, that the axis 21 never comes into contact with the piece goods 9. The deflection axis 21 can be a rotatably supported axis or a deflection rod made of a suitable material in order to keep friction losses and wear and tear as low as possible, such as made of Teflon, the arrangement of the springs 23 in corresponding bushes 25 forming counter bearings is provided on both sides of the deflection axis 21. The arrangement of the bushes 25 with the springs 23 and the deflection axis 21 is, as shown, also with the tilting mechanism
O PI 5 auf ippbar, um einerseits einen fertiggestellten Wickel herauszunehmen und um, bei Wickeln mit Kern, einen neuen Kern 13 einzulegen bzw. allenfalls si¬ cherzustellen, dass das erste Stückgut eines neu zu erstellenden Wickels von den vorgesehenen seitlichen Greifdornen 15 sauber ergriffen wird. Anstatt des Vorsehens einer Umlenkachse 21 , die auch aus beid- seitig in den Bahnbereich einragenden Bolzen gebildet sein kann, kann die Umlenkung gegen den Druck eines Gas- bzw. Luftstrahls 27 erfolgen, der durch eine schematisch dargestellte, ebenfalls mit dem Kipp¬ mechanismus 5 verbundene Düsenanordnung 29 gebildet wird. Vorzugsweise ist dabei die Düsenanordnung 29, wie mit dem Doppelpfeil dargestellt, exakt positionier- bar, um einen möglichst grossen Umschlingungsbereich 17 zu bilden. Der Kern 13 bzw. die beiden seitlichen Dornen 15 sind, allenfalls gegen die Kraft einer ein- oder beidseitig vorgesehenen Federanordnung 31 , senk¬ recht zur Zuspeiseebene 8, verschiebliσh gelagert. Eine Antriebsrolle 33 durch einen Antrieb, wie einen Elektromotor 35, getrieben, liegt in der Verlängerung der Verschiebungsbahn von Kern 13 bzw. Greifdornen 15. Die Zuspeiseebene 8 des Endlosbandes 1 bildet auch zur Antriebsrolle 33 eine Tagentialebene, die Antriebsrolle 33 berührt das Endlosband 1 , entlang einer Linie, die, abgesehen von der Trennung, durch ein jeweils zugeführtes Stückgut 9 mit der Mantelli¬ nie am Wickel 19 übereinstimmt, woran sich die Zu¬ speiseebene 8 tangential schmiegt. Wie nun ersicht- lieh, ist erfindungsgemäss die Zuspeiseebene 8 in ihrer Ausbildung unabhängig vom Wickelradius lage¬ konstant, beispielsweise horizontal und tangentialO PI 5 on ippbar, on the one hand to take out a finished winding and, in the case of winding with a core, to insert a new core 13 or at most to ensure that the first piece goods of a new winding to be created are gripped neatly by the provided lateral gripping spikes 15. Instead of providing a deflection axis 21, which can also be formed from bolts projecting into the web area on both sides, the deflection can take place against the pressure of a gas or air jet 27, which is represented by a schematically illustrated mechanism 5, also with the tilting mechanism 5 connected nozzle assembly 29 is formed. In this case, the nozzle arrangement 29 can preferably be positioned exactly, as represented by the double arrow, in order to form the largest possible wrap area 17. The core 13 or the two lateral mandrels 15 are, at most against the force of a spring arrangement 31 provided on one or both sides, mounted displaceably perpendicular to the feed plane 8. A drive roller 33 driven by a drive, such as an electric motor 35, lies in the extension of the displacement path of the core 13 or gripping mandrels 15. The feed plane 8 of the endless belt 1 also forms a tagential plane to the drive roller 33, the drive roller 33 touches the endless belt 1, along a line which, apart from the separation, coincides with the Mantelli¬ never on the winding 19 by a piece goods 9 fed in each case, to which the feed plane 8 nestles tangentially. As can now be seen, according to the invention, the feed plane 8 is positionally constant in its design, regardless of the winding radius, for example horizontally and tangentially

O PI b WIPO an den Wickel 19 herangeführt. Um sicherzustellen,dass bei zunehmendem Wickelradius, wie gestrichelt darge¬ stellt, genügend Länge des Endlosbandes 1 zur Verfügung steht, ist eine Bandreserve vorgesehen, indem in einer Reserveschlaufe 37, eine Freilauf-Umlenkrolle 3a, bei¬ spielsweise mit einem Gewicht 39 belastet, hängt. Bei zu¬ nehmend benötigter Länge des Endlosbandes 1 für den Um¬ schlingungsbereich 17, wird die Reserveschlaufe 37 ver¬ ringert, wobei das Gewicht 39 die Spannung des Endlos- bandes sicherstellt. Der Umschlingungsbereich 17 übt, wie mit F dargestellt, unabhängig von der Lage des Wickel¬ kernes 13 bzw. der Greifdorne 15, generell der Wickel¬ achse A, einen wenigstens nahezu konstanten Anpressdruck auf die jeweils oberste Stückgutlage des Wickels 19 aus. Zwischen den auf dem Wickel 19 jeweils wirkenden Kräften sucht sich stets eine Gleichgewichtslage einzustellen. Da¬ bei kann sich die Wickelachse A aus ihrer Lage in der Senkrechtebene durch die Achse der Antriebsrolle 33 nach links (Fig. 2) verschieben, was aber den Wickelvorgang grundsätzlich nicht berührt. Es ist ferner möglich, die Umlenkachse 21 durch ihr Eigengewicht, d.h. ohne Kraft der Feder 23," an den Wickel 19 zu pressen. Dazu könnte eine schwenkbare Aufhängung der Achse 21, wie strich¬ punktiert angegeben, Verwendung finden. Der Winkelpunkt kann fest oder schwenkbar sein. In diesem Falle uss die Achse 21 entsprechend zusätzlich geführt werden, um die Zuspeiseebene 8 freizuhalten.O PI b WIPO brought up to the winding 19. In order to ensure that with increasing winding radius, as shown in dashed lines, there is sufficient length of the endless belt 1, a belt reserve is provided in that a free-wheel deflection roller 3a, for example loaded with a weight 39, hangs in a reserve loop 37 . As the length of the endless belt 1 for the looping area 17 increases, the reserve loop 37 is reduced, the weight 39 ensuring the tension of the endless belt. As shown with F, the wrap area 17 exerts an at least almost constant contact pressure on the uppermost piece goods layer of the winding 19, regardless of the position of the winding core 13 or the gripping mandrels 15, generally the winding axis A. An equilibrium position is always sought between the forces acting on the winding 19. The winding axis A can shift from its position in the vertical plane through the axis of the drive roller 33 to the left (FIG. 2), but this does not fundamentally affect the winding process. It is also possible, the deflecting axle 21 by its own weight, that is to say without force of the spring 23 'to press on the winding 19th This could a pivotable mounting of the axle 21, as indicated dotted dash-, be used. The angular point can be fixed or In this case, the axis 21 must be additionally guided in order to keep the feed level 8 clear.
In Fig. 2 ist die Anordnung gemäss Fig. 1 für kern- bzw. dornloses Wickeln dargestellt. Sie entspricht weitgehendst der Darstellung von Fig. 1 und es sind deshalb dieselben Bezugszeichen für gleiche Teile eingesetzt. Es wird auf eine nochmalige Beschreibung der Anordnung verzichtet, bis auf die nachfolgende Beschreibung des prinzipiellen Unterschiedes der hier dargestellten AusführungsVariante. Wie bereits er¬ wähnt wurde, ist anzustreben, die Stückgüter ohne Vorsehen eines Kernes bzw. ohne Einsatz von seitli- chen Greifdornen zu wickeln. Es soll nach einer Ein¬ rollung der Frontpartie eines ersten zugeführten Stückgutes für einen zu bildenden Wickel, dieses erste Stückgut mit seiner eingerollten Frontpartie die Wickelachse A bilden. Nebst einer wesentlichen Vereinfachung der Anordnung und der Reduzierung ihrer Störanfälligkeit, ist mit diesem Vorgehen eine dich¬ tere Wicklung möglich, d.h. bei vorgegebenem Wickel¬ durchmesser werden mehr Stückgüter gewickelt als ins¬ besondere beim Vorsehen eines Wickelkernes.2 shows the arrangement according to FIG. 1 for coreless or mandrelless winding. It corresponds largely to the representation of Fig. 1 and therefore the same reference numerals are used for the same parts. There is no further description of the arrangement, except for the following Description of the basic difference between the versions shown here. As has already been mentioned, the aim is to wind the piece goods without providing a core or without using lateral gripping mandrels. After the front part of a first supplied piece good has been rolled in for a roll to be formed, this first piece goods with its rolled-up front part should form the winding axis A. In addition to a significant simplification of the arrangement and the reduction of its susceptibility to faults, this procedure enables a denser winding, ie more piece goods are wound with a given winding diameter than in particular when a winding core is provided.
Gemäss Fig. 2 und Fig. 3 ragen beidseits Umlenkbolzen 41 in den Bereich des Endlosbandes 1 ein, welch letz¬ teres mindestens auf einer Seite, vorzugsweise aber auf beiden, das Stückgut 9 überragt, wie insbesondere in Fig. 3 ersichtlich. Die Bolzen 41 ragen nur soweit in den Bereich des Endlosbandes 1 ein, als sie nicht in den Breitenbereich des Stückgutes 9 einragen. Zu Beginn des Wickelprozesses ist gemäss Fig. 2 die Umlenkachse 21 in der strichpunktiert eingetragenen Position 21 ' und liegt an den Umlenkbolzen 41 an.According to FIGS. 2 and 3, deflection bolts 41 protrude on both sides into the area of the endless belt 1, the latter projecting beyond the piece goods 9 on at least one side, but preferably on both, as can be seen in particular in FIG. 3. The bolts 41 protrude into the area of the endless belt 1 only to the extent that they do not protrude into the width area of the piece goods 9. At the beginning of the winding process, according to FIG. 2, the deflection axis 21 is in the position 21 ′ shown in broken lines and lies against the deflection bolt 41.
Das Endlosband schlingt sich, ohne dass ein Stückgut vorhanden wäre, um die Umlenkbolzen 41 und läuft, rückgebogen an der Umlenkachse 21 , entlang des ge¬ zeigten Verlaufs. Wird ein erstes Stückgut 9 zuge- spiesen, so wird es, wie aus Fig. 3 ersichtlich, in dieser Initial-Minimalschlauf 17' des Endlosbandes 1 um die Bolzen 41 , ohne letztere zu berühren, ein- gerollt und die nachfolgenden Stückgüter 9 darüber gerollt. In Fig. 3 ist strichpunktiert die Konstel¬ lation bei bereits gewachsenem Wickel dargestellt. Auf diese Art und Weise erübrigt sich, wie erwähnt, das Vorsehen von Wickelkernen und das exakt gesteuer¬ te Zuführen von seitlichen Greifdornen.The endless belt loops around the deflection bolts 41 and runs without a piece goods being present, bent back on the deflection axis 21, along the course shown. If a first piece good 9 is fed in, then, as can be seen from FIG. 3, it is inserted in this initial minimal loop 17 'of the endless belt 1 around the bolts 41 without touching the latter. rolled and the following piece goods 9 rolled over it. 3, the configuration is shown with a dash-dot line when the winding has already grown. In this way, as mentioned, the provision of winding cores and the precisely controlled feeding of lateral gripping mandrels are unnecessary.
Mit dem beschriebenen Verfahren bzw. der beschrie¬ benen Vorrichtung, gemäss dem Verfahren arbeitend, wird es möglich, heikle Stückgüter, wie Kehrichtsäcke und andere aus höchstflexiblem Kunststoffmaterial gefertigte Güter, einzeln zu wickeln, allenfalls ohne Kerne bzw. Dornen, womit ein Wickel realisiert wird, von welchem der Verbraucher mühelos ein benötigtes Stückgut, wie ein einzusetzender Kehrichtsack, nach dem andern abziehen kann. Dasselbe Verfahren bzw. dieselbe Vorrichtung eignet sich auch für eine Viel¬ zahl ähnlich kritisch zu wickelnder Güter, wie von Schutzüberzügen für Autositze aus Kunststoffolie, Haushaltbeuteln, Aluminiumfolienabschnitten, Haus¬ haltfolienabschnitten etc. With the described method or the described device, working according to the method, it becomes possible to individually wind up delicate piece goods, such as rubbish bags and other goods made of highly flexible plastic material, at most without cores or thorns, with which a winding is realized , from which the consumer can easily pull off a required piece of goods, such as a garbage bag to be used, after the other. The same method or the same device is also suitable for a large number of similarly critical goods to be wound, such as protective covers for car seats made of plastic film, household bags, aluminum foil sections, household film sections etc.
