Definitions
- the invention relates to a drivable cloth winding roll according to the preamble of claim 1.
- a drivable cloth winding roll of this kind is from the EP-A-0 795 402 known. It contains a sleeve which is completely severed by a passage slot, so that the sleeve (2) has opposite end portions. The one end portion is an angled from the sleeve circumference to the sleeve center attachment portion which is provided with projections to which the perforated end portion of a cloth is suspended. The angled end portion of the sleeve extends into a longitudinal groove of a core, upon rotation of the cloth is wound onto the sleeve, wherein the tension of the cloth reduces the diameter of the sleeve and thereby biases the sleeve on the core.
- the DE 195 43 518 A1 shows a drivable winding roll of this type, in which the sleeve is formed by a tube which is attachable to a shaft. For winding a washing cloth on the tube this is rotatably connected to the shaft and the shaft is rotatably mounted in bearings of a device which is used for washing cylinder jacket surfaces in rotary printing presses.
- a washing device of this kind is for example from the US 4,344,361 ( DE 30 05 469 C2 ) known.
- Rotary bodies to be cleaned in printing machines are in particular blanket cylinders, plate cylinders, impression cylinders, dampening rollers and guide rollers. Instead of cleaning, the invention can also be used only for moistening be used by surfaces.
- the invention can be used both as a cleaning cloth winding roll and as a dirty cloth winding roll. It has special advantages as a dirty cloth winding roll.
- the dirty cloth or cloth must be removed from the winding roll at the end of the winding process for cleaning or disposal as a disposable product.
- an unwinding process is required.
- the unwinding is often done by a worker in the printing plant in that he puts the dirty cloth winding roll on the floor and rolls there. This not only takes time and space, but also creates environmental pollution, as the ink dust from the dirt cloth falls to the ground and is also whirled into the air.
- the unrolled protective cloth has a much larger volume than the wound soiled cloth, which is disadvantageous in the storage or disposal of the wash cloth.
- Bobbins have a small outer diameter, for example less than 3 cm, in relation to a large length, for example more than 200 cm. They must be connectable to a rotating drive device.
- the invention enables the problem to be solved, a cloth roll form such that a cloth without slip on them can be wound up, and that after winding the winding roll in a simple manner and can be removed quickly from the cloth roll axially without the cloth roll to be unwound needs. Furthermore, the cloth winding roll to be produced in a simple manner, inexpensive and easy to use.
- the invention has the advantage that the winding roll is simple and inexpensive to produce and can be used in a simple manner, without causing pollution.
- the "adjustment of the core relative to the sleeve" is realized in that by axial insertion of the core into the sleeve, the sleeve is expandable against its spring tension to its expanded diameter, and that by axial removal of the core from the sleeve, the sleeve by its own spring tension on its reduced diameter is independently contractible.
- This embodiment is particularly simple and inexpensive to produce and can be positioned in a particularly simple way as a winding roll in a cloth roll and axially removable therefrom without the cloth roll must be handled.
- the core could be multi-part and its parts relative to each other adjustable to change its Druchmesseriere.
- the cloth entrainment means extends at least at the enlarged diameter of the sleeve to a larger sleeve radius than the rest of the sleeve peripheral region.
- a preferred embodiment is that the sleeve has the shape of a spiral spring at least at reduced diameter. This avoids extending through the entire sleeve longitudinal gap, which could lead to accidents, such as skin injury to an operator.
- the cloth-engaging means of the radially inner end section is covered by the radially outer end section only when the diameter of the sleeve is reduced, but with expanded diameter of the sleeve, by this cloth-engaging means from the previously radially outer end section in the sleeve circumferential direction is distanced and exposed for contacting the cloth.
- the cloth entrainment means is formed so that it protrudes from the otherwise preferably smooth outer peripheral surface of the sleeve and has edges, hooks, tips or other protrusions on which the cloth to be wound hangs and thereby by the sleeve in the direction of rotation, ie in the winding, is taken, so that the cloth is wound on the sleeve.
- the cloth entrainment means may by an attached to the sleeve element, for. As an anti-slip coating, or be formed by a part of the sleeve itself, for. B.
- the sleeve may be formed such that the end portions of the sleeve at extended Diameter of the sleeve lie on the same sleeve radius and define a circumferentially open sleeve gap between them, and lie at a reduced diameter of the sleeve on a different same sleeve radius.
- the required for driving the winding roll rotatable connection between the core and the sleeve can be formed in that the sleeve is clamped with a particularly strong spring force on the core.
- the extraction and also the insertion of the core into the sleeve can be carried out with much less force when the sleeve is only slightly stretched on the core, only to expand the sleeve in the required manner, and the non-rotatable connection between the sleeve and core is formed by a positive rotation lock, by which both are connected together for common rotational movement.

Zu reinigende Rotationskörper sind in Druckmaschinen insbesondere Gummituchzylinder, Plattenzylinder, Gegendruckzylinder, Feuchtwerkswalzen und Leitwalzen. Anstatt zum Reinigen kann die Erfindung auch lediglich zum Befeuchten von Oberflächen verwendet werden.Rotary bodies to be cleaned in printing machines are in particular blanket cylinders, plate cylinders, impression cylinders, dampening rollers and guide rollers. Instead of cleaning, the invention can also be used only for moistening be used by surfaces.
Die Erfindung ist sowohl als Saubertuch-Wickelrolle als auch als Schmutztuch-Wickelrolle verwendbar. Besondere Vorteile hat sie als Schmutztuch-Wickelrolle. Das schmutzige Tuch oder Schmutztuch muß am Ende des Aufwickelvorganges von der Wickelrolle entfernt werden zur Reinigung oder zum Wegwerfen als Wegwerfprodukt. Hierzu ist ein Abwickelvorgang erforderlich. Das Abwickeln erfolgt häufig durch einen Arbeiter in der Druckerei dadurch, daß er die Schmutztuch-Wickelrolle auf den Boden legt und dort abrollt. Dies benötigt nicht nur Zeit und Platz, sondern erzeugt auch eine Umweltverschmutzung, da der Druckfarbenstaub aus dem Schmutztuch auf den Boden fällt und auch in die Luft aufgewirbelt wird. Das abgerollte Schutztuch hat ein wesentlich größeres Volumen als das gewickelte Schmutztuch, was nachteilig ist bei der Aufbewahrung oder Entsorgung des Waschtuches.The invention can be used both as a cleaning cloth winding roll and as a dirty cloth winding roll. It has special advantages as a dirty cloth winding roll. The dirty cloth or cloth must be removed from the winding roll at the end of the winding process for cleaning or disposal as a disposable product. For this purpose, an unwinding process is required. The unwinding is often done by a worker in the printing plant in that he puts the dirty cloth winding roll on the floor and rolls there. This not only takes time and space, but also creates environmental pollution, as the ink dust from the dirt cloth falls to the ground and is also whirled into the air. The unrolled protective cloth has a much larger volume than the wound soiled cloth, which is disadvantageous in the storage or disposal of the wash cloth.
Aus der
Wickelrollen haben einen kleinen Außendurchmesser, beispielsweise weniger als 3 cm, im Verhältnis zu einer großen Länge, beispielsweise mehr als 200 cm. Sie müssen mit einer sie drehenden Antriebsvorrichtung verbindbar sein.Bobbins have a small outer diameter, for example less than 3 cm, in relation to a large length, for example more than 200 cm. They must be connectable to a rotating drive device.
Durch die Erfindung soll die Aufgabe gelöst werden, eine Tuchwickelrolle derart auszubilden, daß ein Tuch schlupffrei auf sie aufwickelbar ist, und daß nach dem Aufwickeln die Wickelrolle auf einfache Weise und schnell aus dem Tuchwickel axial herausgenommen werden kann, ohne daß der Tuchwickel abgewickelt zu werden braucht. Ferner soll die Tuchwickelrolle auf einfache Weise herstellbar, preiswert und auf einfache Weise benutzbar sein.The invention enables the problem to be solved, a cloth roll form such that a cloth without slip on them can be wound up, and that after winding the winding roll in a simple manner and can be removed quickly from the cloth roll axially without the cloth roll to be unwound needs. Furthermore, the cloth winding roll to be produced in a simple manner, inexpensive and easy to use.
Diese Aufgabe wird gemäß der Erfindung durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is achieved according to the invention by the characterizing features of claim 1.
Die Erfindung hat den Vorteil, daß die Wickelrolle auf einfache Weise und preiswert herstellbar ist und auf einfache Weise benutzbar ist, ohne daß eine Umweltverschmutzung entsteht.The invention has the advantage that the winding roll is simple and inexpensive to produce and can be used in a simple manner, without causing pollution.
Weitere Merkmale der Erfindung sind in den Unteransprüchen enthalten.Further features of the invention are contained in the subclaims.
Gemäß der bevorzugten Ausführungsform der Erfindung ist das "Verstellen des Kerns relativ zur Hülse" dadurch realisiert, daß durch axiales Einsetzen des Kerns in die Hülse die Hülse entgegen ihrer Federspannung auf ihren erweiterten Durchmesser expandierbar ist, und daß durch axiales Herausnehmen des Kerns aus der Hülse die Hülse durch ihre eigene Federspannung auf ihren reduzierten Durchmesser selbständig zusammenziehbar ist. Diese Ausführungsform ist besonders einfach und preiswert herstellbar und auf besonders einfache Weise als Wickelrolle in einem Tuchwickel positionierbar sowie daraus axial herausnehmbar, ohne daß der Tuchwickel abgewickelt werden muß. Gemäß einer anderen, nicht gezeigten Ausführungsform der Erfindung könnte der Kern mehrteilig und seine Teile relativ zueinander verstellbar sein, um seine Druchmessergröße zu verändern.According to the preferred embodiment of the invention, the "adjustment of the core relative to the sleeve" is realized in that by axial insertion of the core into the sleeve, the sleeve is expandable against its spring tension to its expanded diameter, and that by axial removal of the core from the sleeve, the sleeve by its own spring tension on its reduced diameter is independently contractible. This embodiment is particularly simple and inexpensive to produce and can be positioned in a particularly simple way as a winding roll in a cloth roll and axially removable therefrom without the cloth roll must be handled. According to another, not shown embodiment of the invention, the core could be multi-part and its parts relative to each other adjustable to change its Druchmessergröße.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß das Tuchmitnahmemittel mindestens beim erweiterten Durchmesser der Hülse sich auf einen größeren Hülsenradius erstreckt als der restliche Hülsenumfangsbereich. Dadurch genügen geringe radiale Expansionen und Kontraktionen der Hülse, um sie mit dem Tuch in Eingriff bzw. außer Eingriff zu bringen.According to a further feature of the invention it is provided that the cloth entrainment means extends at least at the enlarged diameter of the sleeve to a larger sleeve radius than the rest of the sleeve peripheral region. As a result, small radial expansions and contractions of the sleeve are sufficient to engage and disengage from the cloth.
Ferner besteht eine bevorzugte Ausführungsform darin, daß die Hülse mindestens bei reduziertem Durchmesser die Form einer Spiralfeder hat. Dadurch wird ein sich durch die gesamte Hülse erstreckender Längsspalt vermieden, welcher zu Unfällen, beispielsweise Hautverletzungen einer Bedienungsperson, führen könnte.Furthermore, a preferred embodiment is that the sleeve has the shape of a spiral spring at least at reduced diameter. This avoids extending through the entire sleeve longitudinal gap, which could lead to accidents, such as skin injury to an operator.
Die Unfallgefahr wird weiter reduziert, wenn gemäß der Erfindung vorgesehen wird, daß nur bei reduziertem Durchmesser der Hülse das Tuchmitnahmemittel des radial inneren Endabschnittes von dem radial äußeren Endabschnitt überdeckt ist, jedoch bei erweitertem Durchmesser der Hülse dieses Tuchmitnahmemittel von dem zuvor radial äußeren Endabschnitt in Hülsenumfangsrichtung distanziert ist und freiliegt zur Kontaktierung des Tuches.The risk of accidents is further reduced if, according to the invention, it is provided that the cloth-engaging means of the radially inner end section is covered by the radially outer end section only when the diameter of the sleeve is reduced, but with expanded diameter of the sleeve, by this cloth-engaging means from the previously radially outer end section in the sleeve circumferential direction is distanced and exposed for contacting the cloth.
Das Tuchmitnahmemittel ist derart ausgebildet, daß es aus der ansonsten vorzugsweise glatten Außenumfangsfläche der Hülse herausragt und Kanten, Haken, Spitzen oder andere Vorsprünge hat, an welchen das aufzuwickelnde Tuch hängen bleibt und dadurch von der Hülse in Drehrichtung, d.h. in Aufwickelrichtung, mitgenommen wird, so daß das Tuch auf die Hülse gewickelt wird. Das Tuchmitnahmemittel kann durch ein an der Hülse befestigtes Element, z. B. einen Anti-Rutsch-Belag, oder durch einen Teil der Hülse selbst gebildet sein, z. B. durch einen gerändelten Außenumfangsbereich an der Hülse oder durch Materialabwinkelungen oder Durchbrüche mit nach außen wegragenden Durchbruchspitzen des Hülsenmaterials, wie dies beispielsweise von Lebensmittel-Reibelementen, beispielsweise Kartoffelreibern und Käsereibern, bekannt ist.The cloth entrainment means is formed so that it protrudes from the otherwise preferably smooth outer peripheral surface of the sleeve and has edges, hooks, tips or other protrusions on which the cloth to be wound hangs and thereby by the sleeve in the direction of rotation, ie in the winding, is taken, so that the cloth is wound on the sleeve. The cloth entrainment means may by an attached to the sleeve element, for. As an anti-slip coating, or be formed by a part of the sleeve itself, for. B. by a knurled outer peripheral portion of the sleeve or by Materialabwinkelungen or breakthroughs with outwardly projecting breakthrough tips of the sleeve material, as is known for example from food friction elements, such as potato drippers and Käsereibern.
Hautverletzungen an Personen und Verkratzen von anderen Gegenständen kann auch dadurch vermieden werden, daß nur der radial innere Endabschnitt mit dem Tuchmitnahmemittel versehen ist, daß der radial äußere Endabschnitt an seinem in Umfangsrichtung zeigenden Rand Einschnitte aufweist, in welche das Mitnahmemittel in Hülsenumfangsrichtung hinein- und herausbewegbar ist, so daß das Mitnahmemittel bei reduziertem Durchmesser in den Einschnitten positioniert ist, wohingegen das Mitnahmemittel bei erweitertem Durchmesser von den Einschnitten in Hülsenumfangsrichtung distanziert ist und freiliegt zur Kontaktierung des Tuches. Verletzungen und Verkratzungen werden bei einer solchen Lösung besonders dann vermieden, wenn das Tuchmitnahmemittel (Anti-Rutsch-Belag, Vorsprünge, etc.) nicht höher ist als die Dicke des Hülsenmaterials.Skin injury to persons and scratching of other objects can also be avoided by providing only the radially inner end portion with the cloth entrainment means that the radially outer end portion has cuts at its circumferentially facing edge into which the entrainment means can be moved in and out of the sleeve circumferential direction is, so that the driving means is positioned at a reduced diameter in the incisions, whereas the extended diameter driving means of the incisions in the sleeve circumferential direction is distant and exposed for contacting the cloth. Injuries and scratches are avoided in such a solution, especially when the cloth-engaging means (anti-slip coating, projections, etc.) is not higher than the thickness of the sleeve material.
Wenn das Tuchmitnahmemittel so ausgebildet ist, daß Verletzungen von Personen oder Kratzer an anderen Gegenständen damit nicht zu befürchten sind oder vernachlässigbar klein sind, so daß es mehr auf eine preiswerte Herstellmöglichkeit ankommt, kann die Hülse derart ausgebildet sein, daß die Endabschnitte der Hülse bei erweitertem Durchmesser der Hülse auf gleichem Hülsenradius liegen und zwischen sich einen in Umfangsrichtung offenen Hülsenspalt begrenzen, und bei reduziertem Durchmesser der Hülse auf einem anderen gleichen Hülsenradius liegen.If the cloth entrainment means is designed so that injury to persons or scratches on other objects are not to be feared or negligible, so that it depends more on a low-cost manufacturing option, the sleeve may be formed such that the end portions of the sleeve at extended Diameter of the sleeve lie on the same sleeve radius and define a circumferentially open sleeve gap between them, and lie at a reduced diameter of the sleeve on a different same sleeve radius.
Die zum Antreiben der Wickelrolle erforderliche drehfeste Verbindung zwischen dem Kern und der Hülse kann dadurch gebildet sein, daß die Hülse mit besonders starker Federkraft auf den Kern aufgespannt ist. Je stärker die Hülse auf den Kern federelastisch gespannt ist, desto schwerer ist es aber, den Kern aus der Hülse herauszuziehen, nachdem ein Tuchwickel auf die Hülse aufgewickelt wurde. Das Herausziehen und auch das Einsetzen des Kerns in die Hülse kann mit wesentlich weniger Kraftaufwand dann durchgeführt werden, wenn die Hülse nur schwach auf den Kern aufgespannt ist, lediglich um die Hülse in der erforderliche Weise zu expandieren, und die drehfeste Verbindung zwischen Hülse und Kern durch eine formschlüssige Drehsicherung gebildet ist, durch welche beide zur gemeinsamen Drehbewegung miteinander verbunden sind.The required for driving the winding roll rotatable connection between the core and the sleeve can be formed in that the sleeve is clamped with a particularly strong spring force on the core. The stronger the sleeve is stretched resiliently on the core, the harder it is, however, to pull the core out of the sleeve after a cloth wrap has been wound onto the sleeve. The extraction and also the insertion of the core into the sleeve can be carried out with much less force when the sleeve is only slightly stretched on the core, only to expand the sleeve in the required manner, and the non-rotatable connection between the sleeve and core is formed by a positive rotation lock, by which both are connected together for common rotational movement.
