Abstract

The adjuster and/or fixer are fixed relative the toolholder for the pre-slit rolls (23,25) by means of permanent magnets here for use in an envelope machine. The magnets and a control element serve a row of suction holes round the circumference of the pre-slitter (28,29) rolls (23,25), with the suction hole row acting as holder and the pre-slit rolls as toolholders. The control element and magnets thus set and fix the positions and the hole row or other roll (23 or 25) has an adjustable holder (31). Magnets and suction holes are placed on different roll radii. The magnets stand like poles facing one another or vice versa and the group of magnets can be replaced by a single magnet.

Bei der Herstellung von Briefumschlägen 1, 101 gemäß den Figuren 8 bzw. 11 ist es notwendig, in der noch zusammenhängenden Papierbahn oder in den bereits vereinzelten Briefumschlagzuschnitten 2, 102 gemäß den Figuren 9 bzw. 10 in Längsrichtung, d. h. in Transportrichtung liegende (siehe Pfeil in Fig. 9 bzw. 10) Längsvorbrüche 3, 103 und 4, 104 und quer dazu Quervorbrüche 5, 105 und 6, 106 vorzusehen, damit aus dem Briefumschlagzuschnitten 2, 102 ein Briefumschlag 1, 101 durch Umfalten und Verkleben der Seitenteile 7, 107 und 8, 108 mit dem Rückenteil 9, 109 hergestellt werden kann. Der Briefumschlag 1 gemäß Fig. 8 weist noch einen zusätzlichen, dritten Quervorbruch 10 für eine zunächst umgelegte Gegenklappe 11 auf. Der Briefumschlag 101 gemäß Fig. 11 weist ebenfalls einen dritten Vorbruch zum Wiederaufrichten der Schließklappe 112 auf. Der Quervorbruch 10, 110 wird auf einer Seite des Briefumschlagzuschnittes 2, 102 eingebracht, die der Seite der Quervorbrüche 5, 105 bzw. 6, 106 gegenüber liegt. Bis auf die Schließklappen stimmen die Briefumschläge 1, 101 weitgehend überein. So sind die Seitenteile 7, 107 und 8, 108 um Längsvorbrüche 3, 103 und 4, 104 und die Schließklappe 12, 112 um den Quervorbruch 6, 106 sowie das Vorderteil 13, 113 und das Rückenteil 9, 109 um den Quervorbruch 5, 105 aufeinander faltbar.In the production of envelopes 1, 101 according to FIGS. 8 or 11 it is necessary in the still contiguous Paper web or cut into the already isolated envelope 2, 102 according to Figures 9 and 10 in the longitudinal direction, d. H. in Transport direction lying (see arrow in Fig. 9 or 10) Longitudinal breaks 3, 103 and 4, 104 and transverse transverse breaks 5, 105 and 6, 106 to be cut out of the envelope 2, 102 an envelope 1, 101 by folding and gluing the Side parts 7, 107 and 8, 108 made with the back part 9, 109 can be. The envelope 1 according to FIG. 8 also has one additional, third transverse advance 10 for an initially folded Counter flap 11 on. The envelope 101 according to FIG. 11 has also a third advance to rebuild the Flap 112 open. The transverse advance 10, 110 is on one side of the envelope blank 2, 102 introduced that the side of the Cross breaks 5, 105 and 6, 106 opposite. Except for the Envelopes 1, 101 are largely correct match. So the side parts 7, 107 and 8, 108 are longitudinal breaks 3, 103 and 4, 104 and the closing flap 12, 112 around the transverse advance 6, 106 and the front part 13, 113 and the back part 9, 109 around the Cross advance 5, 105 foldable on top of each other.

Zur Herstellung der Quervorbrüche 5, 105 bzw. 6, 106 und 10, 110 ist eine Quervorbruchstation 21 in einer Briefumschlagmaschine vorgesehen und umfaßt mehrere Walzen und Rollen, bei denen es sich gemäß dem in Fig. 1 schematisch dargestellten Ausführungsbeispiel um eine Zuführwalze 22 und in Transportrichtung um eine erste Quervorbruchwalze 23 mit einer Gegenwalze 24 sowie um eine zweite Quervorbruchwalze 25 mit einer zugehörigen Gegenwalze 26 und ferner um eine ebenfalls nur schematisch dargestellte Transportwalze 27 handelt. Ein Briefumschlagzuschnitt 2 ist in Fig. 1 strichpunktiert auf Teilen des Umfanges der beiden Quervorbruchwalzen 23 und 25 dargestellt.For the production of the transverse incisions 5, 105 or 6, 106 and 10, 110 a cross pre-break station 21 in an envelope machine provided and includes several rollers and rollers, which are according to the embodiment shown schematically in FIG. 1 around a feed roller 22 and in the transport direction around a first one Cross advance roller 23 with a counter roller 24 and a second Cross advance roller 25 with an associated counter roller 26 and also a transport roller, also shown only schematically 27 acts.

Die Quervorbruchwalzen 23 und 25 tragen Vorbruchmesser 28, 29 und 30. Dabei gilt grundsätzlich, dass ein Vorbruchmesser wie z. B. das Vorbruchmesser 28 auf der zugehörigen Quervorbruchwalze 25 starr angeordnet ist, während das andere Vorbruchmesser 29 in Umfangsrichtung verstellbar ist. Dies ist im Einzelnen in Fig. 1 nicht dargestellt.The transverse pre-break rollers 23 and 25 carry pre-break knives 28, 29 and 30. The basic rule is that a pre-break knife such as B. that Vorbruchmesser 28 rigidly on the associated transverse preliminary roller 25 is arranged while the other pre-breaking knife 29 in Circumferential direction is adjustable. This is not the case in detail in FIG. 1 shown.

Die Lage des in Fig. 1 schematisch strichpunktiert dargestellten Briefumschlagzuschnittes bezogen auf die Lage der Vorbruchmesser 28, 29 und 30 entspricht ebenfalls nicht der tatsächlichen Arbeitsposition. Die beiden Quervorbruchwalzen 23 und 25 mit dem/den jeweils starr angeordneten Vorbruchmesser 28 und ihre Halteeinrichtungen 31 und 31' für den Briefumschlagzuschnitt 2 müssen gegenüber der Darstellung in Fig. 1 noch eingestellt und fixiert werden.The position of the one shown schematically in dash-dot lines in FIG. 1 Envelope cut based on the position of the pre-break knife 28, 29 and 30 also do not correspond to the actual one Working position. The two transverse advance rollers 23 and 25 with the respective rigidly arranged pre-breaking knife 28 and their Holding devices 31 and 31 'for the envelope blank 2 must still be set and fixed compared to the representation in Fig. 1 become.

In der Regel wird ein Briefumschlagzuschnitt 2, 102 durch die Quervorbruchstation 21 von den verschiedenen, dort befindlichen Walzen und Rollen gezogen. Dazu übernimmt die Halteeinrichtung 31' auf der ersten Quervorbruchwalze 23 den Briefumschlagzuschnitt 2 von der Zuführwalze 22 und gibt ihn beim Durchlauf an die zweite Quervorbruchwalze 25 ab, wozu deren Halteeinrichtung 31 ebenfalls das vorlaufende Ende 32 des Briefumschlagzuschnittes taktgenau übernimmt. Die beiden Halteeinrichtungen 31 und 31 'bestehen aus einer grundsätzlich bekannten, mit Unterdruck arbeitenden Saugeinrichtung, die Sauglochreihen 33, 33a, 33b usw. mit am Umfang 34 einer jeden Quervorbruchwalze 23, 25 angeordneten Saugöffnungen 35 umfaßt. Die Saugöffnungen 35 einer jeden Sauglochreihe 33 sind durch Bohrungen 36 miteinander verbunden. Die Bohrungen 36 enden jeweils an einer Stirnseite 37 einer jeden Quervorbruchwalze 23 bzw. 25.As a rule, an envelope blank 2, 102 is cut through the Cross pre-break station 21 of the various located there Rolls and rolls drawn. For this purpose, the holding device 31 ' the envelope blank 2 on the first transverse advance roller 23 from the feed roller 22 and passes it to the second as it passes Cross pre-break roller 25, for which their holding device 31 also the leading end 32 of the envelope blank precisely to the clock takes over. The two holding devices 31 and 31 'consist of a basically known, working with negative pressure Suction device, the suction hole rows 33, 33a, 33b etc. with am Circumference 34 of each transverse advance roller 23, 25 arranged Suction openings 35 includes. The suction openings 35 each Row of suction holes 33 are connected to one another by bores 36. The bores 36 each end on an end face 37 of each Cross advance roller 23 or 25.

Stirnseitig schließt an die Vorbruchwalze 23 bzw. 25 ein Steuerventil 38 an und ist an eine Unterdruckleitung 39 angeschlossen. In dem Steuerventil 38 befindet sich ein koaxial gerichteter Saugluftkanal 40 und eine sich in Umfangsrichtung erstreckende Saugluftstrecke 41. Die Verwendung derartiger Halteinrichtungen 31 mit Sauglochreihen am Umfang 34 der Quervorbruchwalzen sowie mit Steuerventilen 38, die Saugluftkanäle 40 und Saugluftstrecken 41 aufweisen, ist grundsätzlich Stand der Technik und bedarf aus diesem Grund keiner weiteren Erläuterung. Das Steuerventil 38 dreht sich jeweils nicht mit der Quervorbruchwalze 23 bzw. 25, die über eine Welle 42 in einem Maschinengestell 43 gelagert und über ein Antriebselement 44 in Drehung versetzt wird.At the end, a control valve connects to the pre-break roller 23 or 25 38 and is connected to a vacuum line 39. By doing Control valve 38 is a coaxially directed suction air duct 40 and a suction air path 41 extending in the circumferential direction Use of such holding devices 31 with rows of suction holes on Scope 34 of the transverse pre-break rollers and with control valves 38, the Have suction air channels 40 and suction air paths 41 is fundamental State of the art and therefore requires no further Explanation. The control valve 38 does not rotate with the Cross pre-break roller 23 or 25, which via a shaft 42 in one Machine frame 43 supported and via a drive element 44 in Rotation is offset.

An dem die Stirnseite 37 aufweisenden Ende 45 der Quervorbruchwalze 23, 25 befindet sich zusätzlich noch ein Steuerelement 46, das relativ zu dem etwa zylindrischen Walzenkörper 47 der Quervorbruchwalze 23, 25 verstellbar ist. Es ist auf dem Walzenkörper 47 geführt bzw. verschwenkbar angeordnet. Es dient zum Öffnen oder Verschließen der Bohrungen 36, die zu den Saugöffnungen 35 am Umfang der Quervorbruchwalze 23, 25 führen.At the end 45 of the end 37 of the Cross advance roller 23, 25 is also a Control element 46, which is relative to the approximately cylindrical roller body 47 of the transverse advance roller 23, 25 is adjustable. It is on the Rolled body 47 guided or pivotally arranged. It serves to open or close the bores 36, which to the Guide suction openings 35 on the circumference of the transverse pre-break roller 23, 25.

Wie aus den Figuren 1, 3 und 5 hervorgeht, weist jede Quervorbruchwalze 23, 25 eine Vielzahl parallel zueinander sowie auf gleichem Radius angeordnete Sauglochreihen 33, 33a, 33b usw. auf. Zu jeder Sauglochreihe 33 usw. gehört eine Bohrung 36. Mit Hilfe des Steuerelementes 35 wird erreicht, dass jeweils nur eine Bohrung 36 oder zwei direkt oder indirekt benachbarte Bohrungen 36 über das Steuerventil 38 an den Unterdruck in der Unterdruckleitung 39 angeschlossen sind. Mit Hilfe des verstellbar am stirnseitigen Ende der Vorbruchwalze 23, 25 angeordneten Steuerelementes 46 werden daher je nach Bedarf die zu der einen oder anderen Sauglochreihe 33, 33a usw. gehörende Bohrung 36 über das Steuerventil 38 an den Unterdruck in der Unterdruckleitung 39 angeschlossen. Dazu weist das Steuerelement 46 mindestens eine Bohrung 48, 49 auf, die auf dem gleichen Radius liegen wie die Bohrungen 36 bzw. wie die sich in Umfangsrichtung im Steuerventil 38 erstreckende Saugluftstrecke 41. In den Bohrungen 36 der angeschlossenen Sauglochreihen herrscht aufgrund der Bohrungen 48 bzw. 49 derselbe Unterdruck wie längs der Saugluftstrecke 41 bzw. wie in der Unterdruckleitung 39.As can be seen from FIGS. 1, 3 and 5, each has Cross advance roller 23, 25 a plurality parallel to each other and on Suction hole rows 33, 33a, 33b etc. arranged at the same radius. A hole 36 belongs to each row of suction holes 33, etc. With the help of the Control element 35 is achieved in that only one bore 36 at a time or two directly or indirectly adjacent holes 36 over the Control valve 38 to the negative pressure in the negative pressure line 39 are connected. With the help of the adjustable at the front end of the Pre-break roller 23, 25 arranged control element 46 are therefore depending on the need for one or the other row of suction holes 33, 33a etc. belonging bore 36 via the control valve 38 to the Vacuum connected in the vacuum line 39. That points to Control element 46 at least one bore 48, 49 on the are the same radius as the bores 36 or as in Suction air path 41 extending in the circumferential direction in the control valve 38. The bores 36 of the connected rows of suction holes prevail due to the holes 48 and 49 the same negative pressure as along the Suction air path 41 or as in the vacuum line 39.

Die Saugluftstrecke 41 erstreckt sich nur über ein begrenztes Bogenstück bis zu einer Zwischenwand. Sodann ist eine Kammer 50 vorgesehen, in der Atmosphärendruck herrscht. Sobald das Steuerelement 46 in den Bereich der Kammer 50 gelangt, bricht der Unterdruck in der/den Bohrungen 36 und somit an den beaufschlagten Sauglochreihen 33 zusammen, mit der Folge, dass die Halteeinrichtung 31, 31' ihre Wirkung verliert.The suction air path 41 extends only over a limited range Elbow piece up to a partition. Then there is a chamber 50 provided in which atmospheric pressure prevails. As soon as that Control element 46 reaches the area of the chamber 50, the breaks Vacuum in the / the bores 36 and thus on the acted upon Suction hole rows 33 together, with the result that the holding device 31, 31 'loses its effect.

Das drehbar oder schwenkbar auf dem Walzenkörper 47 gelagerte Steuerelement 46 dient einerseits zum Anwählen der einen oder anderen Sauglochreihe und andererseits zugleich auch zum Fixieren der angewählten Position. Dies geschieht mit Hilfe von Magneten 51 auf dem Steuerelement 46 und mit Hilfe von Magneten 52 am stirnseitigen Ende 45 des Walzenkörpers 47.That which is rotatably or pivotably mounted on the roller body 47 Control element 46 serves on the one hand to select one or the other another row of suction holes and on the other hand also for fixing the selected position. This is done with the help of magnets 51 on the control element 46 and with the help of magnets 52 on end 45 of the roller body 47.

Gemäß dem in Figuren 3 und 4 dargestellten Ausführungsbeispiel sind die Magnete 51 auf dem Steuerelement 46 ringförmig angeordnet. Grundsätzlich Gleiches gilt für die Magnete 52 am stirnseitigen Ende 45 des Walzenkörpers 47.According to the embodiment shown in Figures 3 and 4 the magnets 51 are arranged in a ring on the control element 46. Basically the same applies to the magnets 52 at the end 45 of the roller body 47.

Die Magnete 51 befinden sich fluchtend in einer ringförmigen Stirnfläche 53 des Steuerelementes 46, das gemäß Ausführungsbeispiel mit einer Bohrung 54 (Fig. 4) auf einem ringförmigen Endstück 55 des Walzenkörpers 47 (Fig. 1) drehbar gelagert ist. Die Magnete 52 befinden sich ebenfalls in einer ringförmigen Stirnfläche 56 am freien Ende 45 des Walzenkörpers 47 derart, dass sie auf demselben Radius liegen wie die Magnete 51 des Steuerelementes 46.The magnets 51 are aligned in a ring End face 53 of the control element 46, which according to Embodiment with a bore 54 (Fig. 4) on a annular end piece 55 of the roller body 47 (Fig. 1) rotatable is stored. The magnets 52 are also in one annular end face 56 at the free end 45 of the roller body 47 such that they lie on the same radius as the magnets 51 of the Control element 46.

Die Anzahl und Lage der Magnete 51 bzw. 52 ist derart gewählt, dass die erwünschten Einstellpositionen erzielbar sind. Dazu können die Magnete 51 und 52 entweder mit entgegengesetzten Polen gemäß Figur 6 unmittelbar in den Einstellpositionen einander gegenüberliegen oder sie können auch mit entgegengesetzten Polen einander gegenüberliegen bzw. relativ zueinander versetzt sein, wie dies in Fig. 7 dargestellt ist.The number and position of the magnets 51 and 52 is selected such that the desired setting positions can be achieved. You can do that Magnets 51 and 52 either with opposite poles as per Figure 6 are directly opposite each other in the setting positions or they can also use opposite poles to each other opposite or offset relative to each other, as shown in Fig. 7 is shown.

Liegen die Magnete 51 und 52 mit entgegengesetzten Polen (Fig. 6) einander gegenüber, so ziehen die Magnete sich gegenseitig und auch die sie tragenden Teile 46 bzw. 47 an. Ein Verstellen der Teile 46 und 47 relativ zueinander ist daher mit einem gewissen Kraftaufwand verbunden. Liegen die Magnete 51 und 52 jedoch mit entgegengesetzten Polen gemäß Fig. 7 einander gegenüber bzw. in ihren jeweiligen Stirnflächen 53 bzw. 56, so stoßen sie sich voneinander ab mit der Folge, dass das Steuerelement 46 relativ leicht zu dem Walzenkörper 47 verstellbar ist, insbesondere wenn die Magnete 51 und 52 zusätzlich in den jeweiligen Einstell- und Rastpositionen zueinander versetzt sind (Fig. 7). Das Steuerelement 46 springt dann von Einstellposition zu Einstellposition und ist in jeder dieser Positionen sicher fixiert.Are the magnets 51 and 52 with opposite poles (Fig. 6) opposite each other, so the magnets pull each other and also the parts 46 and 47 supporting them. An adjustment of the parts 46 and 47 relative to each other is therefore with a certain effort connected. However, the magnets 51 and 52 lie with them opposite poles according to FIG. 7 opposite each other or in their respective end faces 53 and 56, they collide from each other with the result that the control element 46 is relatively light is adjustable to the roller body 47, especially if the Magnets 51 and 52 additionally in the respective setting and Rest positions are offset from each other (Fig. 7). The control 46 then jumps from set position to set position and is in everyone of these positions securely fixed.

Gemäß der Darstellung in Fig. 5 sind die Sauglochreihen 33 und 33b mit Unterdruck beaufschlagt. Außerhalb des Briefumschlagzuschnittes 2 befindliche Saugöffnungen 35 sind jeweils mit einem Klebestreifen 57 abgedeckt, damit Falschluft dort nicht angesaugt wird.As shown in Fig. 5, the suction hole rows 33 and 33b pressurized with vacuum. Outside the envelope blank 2 suction openings 35 are each with an adhesive strip 57 covered, so that false air is not sucked in there.

Fig. 1 zeigt schließlich noch eine Halteeinrichtung 61 für das Steuerventil 38, damit es seine Lage im Maschinengestell 43 nicht verändern kann.1 shows a holding device 61 for the Control valve 38 so that it is not its location in the machine frame 43 can change.

Ferner geht aus Fig. 1 die Lage der Saugluftstrecke 41 hervor, die an der Übergabestelle der Zuführwalze 22 beginnt und kurz vor der Abgabestelle an die zweite Vorbruchwalze 25 endet. 1 shows the position of the suction air path 41, the the transfer point of the feed roller 22 begins and shortly before Delivery point to the second pre-break roller 25 ends.

Das Steuerelemente 46 ist gemäß Ausführungsbeispiel ringförmig und bildet zusammen den an ihm fluchtend angeordneten Magneten 51 und mit den auf demselben Radius stirnseitig in dem Walzenkörper 47 angeordneten Magneten 52 eine Verstell- und Rasteinrichtung 62. Die Magnete 51 und 52 sind zweckmäßigerweise Dauermagnete.The control element 46 is annular and according to the embodiment together forms the magnet 51 and with those on the same radius on the end face in the roller body 47 arranged magnet 52 an adjustment and locking device 62. Die Magnets 51 and 52 are expediently permanent magnets.

Die Magnete 51 bzw. 52 bilden jeweils eine Gruppe in dem Steuerelement 46 bzw. stirnseitig in dem Walzenkörper 47 der Quervorbruchwalze 23 bzw. 25. Eine der beiden Gruppen kann auch aus nur zwei oder gegebenenfalls auch aus einem einzigen Magnet bestehen.The magnets 51 and 52 each form a group in the Control element 46 or the end face in the roller body 47 of the Cross advance roller 23 or 25. One of the two groups can also from only two or possibly from a single magnet consist.

Die Erfindung ist schließlich nicht auf die Verwendung in einer Vorbruchstation einer Briefumschlagmaschine beschränkt. Sie kann auch in anderem Zusammenhang verwendet werden, wenn es darum geht, eine Halteeinrichtung für ein Werkstück und/oder ein Werkzeug relativ zu einem Werkzeugträger in auswählbaren Positionen einzustellen und in der jeweils ausgewählten Position zu fixieren.Finally, the invention is not for use in any Crushing station of an envelope machine limited. she can also be used in another context when it comes to that goes, a holding device for a workpiece and / or a tool relative to a tool carrier in selectable positions adjust and fix in the selected position.
