Abstract

PCT No. PCT/CH96/00018 Sec. 371 Date Nov. 18, 1996 Sec. 102(e) Date Nov. 18, 1996 PCT Filed Jan. 16, 1996 PCT Pub. No. WO96/22243 PCT Pub. Date Jul. 25, 1996An apparatus and method of preparing bundles for binding, where the method is carried out at a high processing frequency and the device is of a compact construction, where bundles of sheets are raised from the upper end of a supply stack of a punching device in a continuous manner by means of an engagement tool and the respective bundle is displaced by a pusher, with the result that its opposite border region projects into a punching device and is processed there. Lifting edges of two rotating disc segments then engage beneath the opposite border of the bundle, the border being retained by the pusher, and raise the border until the region adjoining it is clamped between partially cylindrical clamping surfaces of the disc segments, the clamping surfaces adjoining the lifting edge, and a likewise rotating clamping roller, and the bundle is fed, counter to the displacement direction, to a transportation device, where the bundles are clamped between two pairs of transporting belts and are transported to an end stack. The bundles are turned at the same time they are transported. The bundles follow one after the other at a distance which is smaller than the width of a bundle, with the result that they overlap in an imbricated manner.

Description

Die Erfindung betrifft ein Verfahren gemäss dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens. Derartige Verfahren und Vorrichtungen werden vor allem zur Bearbeitung von Papierblättern eingesetzt, welche, z. B. zwecks Vorbereitung zur Broschierung, gestanzt werden oder welche mit einer Prägung versehen werden. Dabei werden die Blätter in Bündeln einer bestimmten Dicke - z. B. einige Millimeter - automatisch einem Vorratsstapel entnommen, bearbeitet, gewendet und einem Zielstapel zugeführt.The invention relates to a method according to the preamble of claim 1 and a device for performing the Procedure. Such methods and devices are proposed all used for processing sheets of paper, which, e.g. B. to prepare for pamphlet punching or which are embossed. In doing so the leaves in bundles of a certain thickness - e.g. B. some Millimeters - automatically taken from a stack of stocks, processed, turned and fed to a target stack.

Es sind gattungsgemässe Vorrichtungen bekannt (s. z. B. Prospekt der Lloyd Machinery Ltd.: Automatic Punching Machine, Model 340), bei welchen ein zu bearbeitendes Bündel jeweils zu einer Stanzeinrichtung hin vollständig vom Vorratsstapel abgezogen, mittels einer Transporteinrichtung gewendet, in einem Randbereich gestanzt und schliesslich auf einem Zielstapel abgelegt wird.Devices of the generic type are known (see e.g. Brochure from Lloyd Machinery Ltd .: Automatic Punching Machine, Model 340), in which a bundle to be processed each to a punching device completely from Stack of supplies pulled off by means of a transport device turned, punched in an edge area and finally on is placed in a target stack.

Bei dieser Vorgehensweise folgt ein Bündel jeweils dem voraufgehenden in einem Abstand, der mindestens - abhängig von der Ausrichtung der Stanzeinrichtung - der Länge oder Breite des voraufgehenden Bündels entspricht. Dies hat zur Folge, dass die Bearbeitungseinrichtung wegen transportbedingter Verzögerungen nicht mit der prinzipiell möglichen Frequenz arbeitet und der Durchsatz der Vorrichtung verhältnismässig tief bleibt. Ausserdem erfordert der Aufbau derselben viel Raum.With this approach, a bundle follows each preceding at a distance that is at least - dependent on the alignment of the punching device - the length or Corresponds to the width of the preceding bundle. This has to Consequence that the processing device because transport-related delays not with the principle possible frequency works and the throughput of the Device remains relatively deep. Furthermore building it requires a lot of space.

In der DE-A-24 47 601 ist eine weitere gattungsgemässe Vorrichtung beschrieben. Die neben der Stapelauflage angeordnete Versetzungseinrichtung umfasst eine Abhebevorrichtung zum Anheben eines Bündels und einen Halter mit einer Klammer, welche mittels eines von oben auf eine Klemmbacke einwirkenden Stössel schliessbar ist, zum Fassen und Versetzen desselben. Das Bündel wird dann von einer Aufnahmevorrichtung übernommen und zu einer Stanzeinrichtung überführt. Auch hier erfolgt also offenbar ein längerer Transport der einzelnen Bündel vor der Bearbeitung derselben. Es ist davon auszugehen, dass die Vorrichtung prinzipiell gleich arbeitet wie die weiter oben beschriebenen. DE-A-24 47 601 is another generic type Device described. The next to the stacking pad arranged displacement device comprises a Lifting device for lifting a bundle and a holder with a clamp, which is attached to a The plunger acting on the jaw is closable, for gripping and moving it. The bundle is then from one Received device and to a punching device transferred. So here, too, apparently there is a longer one Transport of the individual bundles before processing the same. It is assumed that the device works basically the same as the one above described.

Hier soll die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, schafft ein Verfahren, bei welchem das zu bearbeitende Bündel jeweils um nicht wesentlich mehr als die Breite des zu bearbeitenden Randbereichs gegenüber dem Vorratsstapel versetzt wird, um bearbeitet zu werden. Ebenso wird es nur um etwa die gleiche Distanz zurückgezogen, um die Bearbeitungseinrichtung für das darauffolgende Bündel frei zu machen, das daraufhin seinerseits in die Bearbeitungsposition gebracht wird, ohne dass das erstgenannte Bündel vorgängig vollständig entfernt würde. Da aufeinanderfolgende Bündel so nur über kurze Distanzen gleitend gegeneinander verschoben werden müssen, ist ausserdem die Gefahr elektrostatischer Aufladung, die sonst vor allem bei bestimmten Folien sehr störend sein kann, stark reduziert.The invention is intended to remedy this. The invention how it is characterized in the claims creates one Process in which the bundle to be processed in each case not much more than the width of the work to be done Edge area is offset in relation to the supply stack to be processed. Likewise, it will only be about the same Distance retracted to the machining facility for to release the following bundle, the next one is in turn brought into the processing position without that the first-mentioned bundle is completely removed beforehand would. Because successive bundles only last for a short time Distances have to be shifted smoothly against each other, is also the risk of electrostatic charge, the otherwise be very annoying, especially with certain foils can, greatly reduced.

Oberhalb der Schubeinrichtung 5 ist eine Abzugseinrichtung 8 angebracht, an welche eine Transporteinrichtung 9 unmittelbar anschliesst. Sie umfasst zwei geschlossene, über eine Transportstrecke, welche einen Bogen von ca. 180° beschreibt, parallel geführte Riemenpaare 10a,b. Das Riemenpaar 10a läuft längs der Transportstrecke über eine konvex gebogene Führung, z. B. aus Aluminiumblech. Unterhalb des Endes der Transportstrecke ist eine weitere, vertikale Führungsschiene 11 angeordnet, längs welcher eine weitere Stapelauflage 12 zur Aufnahme eines Zielstapels 13 vertikal verschieblich ist. Die Stapelauflage 12 ist mit Rädern versehen.A trigger device 8 is located above the pushing device 5 attached to which a transport device 9 immediately connects. It includes two closed, over a transport route which has an arc of approximately 180 ° describes, parallel pairs of belts 10a, b. The Belt pair 10a runs along the transport route over a convex curved guide, e.g. B. made of aluminum sheet. Below at the end of the transport route is another vertical one Guide rail 11 arranged, along which another Stack support 12 for receiving a target stack 13 vertically is movable. The stacking pad 12 is with wheels Mistake.

In groben Zügen wird das erfindungsgemässe Verfahren mittels der erfindungsgemässen Vorrichtung wie folgt durchgeführt:The process according to the invention is broadly described by means of of the device according to the invention carried out as follows:

Die Stapelauflage 3 wird jeweils um die Dicke eines zu bearbeitenden Bündels nach oben verschoben, dann das oberste Bündel des Vorratsstapels 4 mittels der Schubeinrichtung 5 derart versetzt, dass sein zu bearbeitender Randbereich in der Stanzeinrichtung 6 liegt, derselbe gestanzt und das Bündel von der Abzugseinrichtung 8 ergriffen und von der Transporteinrichtung 9 dem Zielstapel 13 zugeführt, wobei es zur Beibehaltung der Blattfolge gewendet wird. Die beschriebene Ausbildung der Transporteinrichtung 9 erlaubt den Transport auch verhältnismässig steifer Blätter, da die Transportstrecke einen grossen Krümmungsradius aufweist, wie er mit herkömmlichen, auf Trommeln beruhenden Transporteinrichtungen nur mit unvergleichlich höherem Platzbedarf erzielt werden könnte. Aufeinanderfolgende Bündel werden überlappend bearbeitet und transportiert. Die Stapelauflage 12 wird dabei derart abgesenkt, dass das obere Ende des Zielstapels 13 stets knapp unter der Höhe des Ausgangs der Transporteinrichtung 9 bleibt. Sobald die Stapelauflage 12 Bodennähe erreicht, hält die Stanzvorrichtung an. Die Stapelauflage 12 kann dann auf den Boden abgesenkt, ausgeklinkt und mit dem Zielstapel 13 weggerollt werden.The stack support 3 is increased by the thickness of one editing bundle shifted up, then the top one Bundle of the supply stack 4 by means of the pusher 5 offset in such a way that its edge area to be machined in the punching device 6 lies, the same punched and the Bundle gripped by the trigger device 8 and by the Transport device 9 fed to the target stack 13, wherein it is turned to maintain the sheet sequence. The described design of the transport device 9 allowed the transport of relatively stiff leaves, because the Transport route has a large radius of curvature, such as he with conventional drum-based ones Transport equipment only with incomparably higher Space could be achieved. Consecutive Bundles are processed and transported overlapping. The Stacking support 12 is lowered in such a way that the upper one End of the target stack 13 always just below the level of Exit of the transport device 9 remains. As soon as the Stacking surface 12 reaches the ground, holds the Punching device. The stack pad 12 can then on the Lowered floor, released and with the target stack 13 to be rolled away.

Vor allem bei Blättern kleinen Formats wird (Fig. 1b) der Abstand der Stanzeinrichtung 6 von der Schubeinrichtung 5 entsprechend verkleinert. Da sich solche Blätter in der Regel schlecht in der oben beschriebenen Weise stapeln lassen, ist ein an die Transporteinrichtung 9 anschliessendes Förderband 14 vorgesehen, das z. B. über Zahnräder an die Transporteinrichtung 9 ankuppelbar ist. Es weist am von der Transporteinrichtung 9 abgewandten Ende eine Auffangplatte 15 auf, an welcher sich die Bündel stauen und aufgerichtet werden. Wenn das Förderband 14 voll ist, wird es abgeräumt. Im übrigen läuft die Bearbeitung der Blätter wie oben geschildert ab. Die Blätter können durch das Förderband 14 auch zwecks weiterer Bearbeitung unmittelbar zu einer weiteren Vorrichtung transportiert werden. In diesem Fall entfällt die Auffangplatte 15.Especially with small format sheets (Fig. 1b) Distance between the punching device 6 and the pushing device 5 reduced accordingly. Since such leaves are in the Usually stack poorly as described above is a to the transport device 9th subsequent conveyor belt 14 is provided, the z. B. about Gears can be coupled to the transport device 9. It has at the end facing away from the transport device 9 a collecting plate 15 on which the bundles jam and be erected. When the conveyor belt 14 is full, it will be cleared. Otherwise the processing of the Leaves as described above. The leaves can go through the conveyor belt 14 also for further processing transported directly to another device become. In this case, the collecting plate 15 is omitted.

Wie am besten aus Fig. 2 ersichtlich ist, umfasst die Schubeinrichtung 5 einen Schieber 16, welcher quer zum Vorratsstapel 4 derart, dass er in der Endlage über die Stapelauflage 3 vorsteht, vorschiebbar und zurückziehbar ist. Am Vorderende ist er mit einer konkaven Stossfläche 17 versehen. Sie wird von zwei vom oberen bzw. unteren Ende her etwas nach innen geneigten Streifen gebildet, die einen stumpfen Winkel einschliessen. Weiters umfasst die Schubeinrichtung 5 einen Vorgreifer 18 mit einem auswechselbaren Schnabel 19 zum Eingriff in den Vorratsstapel 4, welcher wie der Schieber 16 vorschieb- und zurückziehbar ist. Der Schnabel 19 weist gemäss Fig. 2 an seinem vorderen Ende eine Schneidkante 20 auf. Diese Ausbildung eignet sich für die Bearbeitung von Blättern aus verhältnismässig dünnem Material wie Papier, da die Schneidkante 20 dann ohne weiteres zwischen zwei aufeinanderliegende Blätter eindringen kann. Bei dickerem Material wie Karton könnte eine Schneidkante jedoch in den Seitenrand eines der Blätter einschneiden, was den Ablauf der Bearbeitung stören und auch zur Beschädigung des Kartons führen könnte. Für die Bearbeitung derartigen Materials wird daher ein Schnabel 19' mit einer niedrigen Stirnfläche 20' mit Querrillen in den Vorgreifer 18 eingesetzt, wie in Fig. 2a dargestellt.As best seen in FIG. 2, the Push device 5 a slide 16 which is transverse to Storage stack 4 such that it in the end position on the Stacking pad 3 protrudes, can be pushed forward and retracted is. At the front end it has a concave butt surface 17 Mistake. It is made up of two from the top and bottom slightly inward sloping stripes formed one Include obtuse angle. Furthermore, the Push device 5 a pre-gripper 18 with a interchangeable beak 19 for engagement in the Storage stack 4, which feeds like the slider 16 and is retractable. The beak 19 indicates according to FIG. 2 a cutting edge 20 at its front end. This Training is suitable for editing sheets relatively thin material like paper, because the Cutting edge 20 then easily between two sheets lying on top of each other can penetrate. With thicker ones However, material such as cardboard could have a cutting edge in the Cut in the side margin of one of the sheets, causing the drain interfere with processing and damage to the carton could lead. For processing such material hence a beak 19 'with a low end face 20' with transverse grooves in the pre-gripper 18, as in Fig. 2a shown.

Der Vorgreifer 18 ist in einer Halterung 21, welche an der Unterseite des Schiebers 16 befestigt ist, in Vorschubrichtung begrenzt verschiebbar gelagert. Die Halterung 21 umfasst eine zum Schieber 16 parallele Bodenplatte 22, welche am vorderen Rand eine Vorderwand 23 trägt mit einer mittigen, von ihrem oberen Rand her eingeschnittenen Ausnehmung 24, durch welche der Vorgreifer 18 ragt, und weiter hinten eine Zwischenwand 25, welche sie mit dem Schieber 16 verbindet und eine Durchführung 26 aufweist. Eine abschliessende doppelte Rückwand 27 bildet eine senkrecht zur Vorschubrichtung ausgerichtete Nut 28, in welche eine Mitnehmerrolle 29 einer Kurbel 30 eingreift. Die seitlich offene Halterung 21 ist an zwei zur Vorschubrichtung parallelen Tragstangen 31a,b verschiebbar aufgehängt. Durch den Raum zwischen der Zwischenwand 25 und der Rückwand 27 ragt ein an den Tragstangen 31a,b befestigter Balken 32 mit einem von seinem oberen Rand her eingeschnittenen Schlitz 33.The pre-gripper 18 is in a holder 21 which on the Bottom of the slider 16 is attached in The feed direction can be moved to a limited extent. The Bracket 21 includes a parallel to the slider 16 Base plate 22, which has a front wall 23 at the front edge bears with a central, from its upper edge incised recess 24 through which the pre-gripper 18 protrudes, and further behind an intermediate wall 25, which they connects to the slide 16 and a bushing 26 having. A final double rear wall 27 forms a groove 28 oriented perpendicular to the feed direction, in which engages a driver roller 29 of a crank 30. The laterally open bracket 21 is on two Feed direction parallel support rods 31a, b slidable hung up. Through the space between the partition 25 and the rear wall 27 protrudes on the support rods 31a, b attached beam 32 with one from its upper edge incised slot 33.

Der Vorgreifer 18 weist (s. auch Fig. 2a) ein Vorgreifergehäuse 34 auf, an dessen Vorderseite der Schnabel 19 an einem mittig nach unten vorspringenden Fortsatz angeschraubt ist. Durch das Vorgreifergehäuse 34 läuft in Vorschubrichtung eine Bohrung 35, welche mit Abstand einen Bolzen 36 umgibt, der an seinem vordersten Abschnitt drehbar und unverschieblich im Vorgreifergehäuse 34 gelagert ist. Sein Vorderende ist von der Vorderseite des Vorgreifers 18 her zugänglich und mit einem Schlitz für den Eingriff eines Schraubenziehers versehen. Der durch die Bohrung 35 ragende Abschnitt des Bolzen 36 trägt ein Gewinde, das mit einer Einstellmutter 37 eingreift. Sie ist gegenüber dem Vorgreifergehäuse 34 verschiebbar, aber wegen eines Zapfens 38, der in einen die Bohrung 35 mit der Oberseite des Vorgreifergehäuses 34 verbindenden Schlitz 39 eingreift, nicht verdrehbar. Der hintere Teil des Bolzen 36 ragt durch die Durchführung 26 in der Zwischenwand 25 und durch den Schlitz 33 im Balken 32. In der Durchführung 26 ist der Bolzen 36 verschiebbar und mindestens vertikal beschränkt kippbar, aber im übrigen praktisch spielfrei geführt, der Schlitz 33 lässt ihm seitlich geringes Spiel.The pre-gripper 18 has (see also FIG. 2a) Pre-gripper housing 34, on the front of which the beak 19 on a centrally projecting projection is screwed on. Through the pre-gripper housing 34 runs in Feed direction a bore 35 which is a distance Surrounds bolt 36 which is rotatable at its foremost portion and is immovably mounted in the pre-gripper housing 34. Its front end is from the front of the pre-gripper 18 accessible and with a slot for engaging one Screwdriver. The protruding through the bore 35 Section of the bolt 36 carries a thread with a Adjusting nut 37 engages. It is opposite to that Gripper housing 34 slidable, but because of a pin 38, which in a bore 35 with the top of Gripper housing 34 engages slot 39, not rotatable. The rear part of the bolt 36 protrudes the implementation 26 in the intermediate wall 25 and through the Slot 33 in the bar 32. In the bushing 26 is the Bolt 36 slidably and at least vertically limited tiltable, but otherwise practically free of play, the Slot 33 leaves little play to the side.

Zwischen der Einstellmutter 37 und einem vor der Zwischenwand 25 verschiebbar auf dem Bolzen 36 sitzenden Abstützring 40 ist eine den Bolzen 36 umgebende Spiralfeder 41 angeordnet. Die Einstellmutter 37 bildet eine erste Federabstützung für die Spiralfeder 41 und die Zwischenwand 25 über den an ihrer Vorderseite anliegenden Abstützring 40 eine zweite. Zwischen der Zwischenwand 25 und dem Balken 32 ist ein Anschlagring 42 unverschieblich am Bolzen 36 befestigt, der mit der Rückseite der Zwischenwand 25 einen Mitnehmeranschlag bildet. An seinem hinteren Ende ist der Bolzen 36 wiederum mit einem Gewinde versehen und trägt hinter dem Balken 32 eine Anschlagmutter 43.Between the adjusting nut 37 and one in front of the Partition 25 slidably seated on the bolt 36 Support ring 40 is a spiral spring surrounding the bolt 36 41 arranged. The adjusting nut 37 forms a first one Spring support for the spiral spring 41 and the intermediate wall 25 via the support ring 40 resting on its front side a second. Between the partition 25 and the beam 32 a stop ring 42 is immovable on the bolt 36 attached to the back of the partition 25 a Driver stop forms. At its rear end is the Bolt 36 in turn is threaded and carries a stop nut 43 behind the bar 32.

Die Spiralfeder 41, welche wie erwähnt über den Abstützring 40 an der Zwischenwand 25 der Halterung 21 abgestützt ist, übt über die Einstellmutter 37 auf den Vorgreifer 18 eine in Vorschubrichtung wirkende Kraft aus. Der Vorgreifer 18 ist daher in der in Fig. 2 gezeigten zurückgezogenen Stellung des Schiebers 16 gegenüber demselben so weit vorgeschoben, wie es der Mitmehmerring 42 erlaubt. Stösst der Vorgreifer 18 beim Vorschub auf einen testen Widerstand, so ist er gegenüber der Halterung 21 gegen die Kraft der Spiralfeder 41 zurückschiebbar. Die Federkraft ist einstellbar, da die Einstellmutter 37 durch Drehung des Bolzen 36 mittels eines an dessen Vorderende angesetzten Schraubenziehers in Vorschubrichtung verschoben werden kann. Verschiebung der Einstellmutter 37 nach vorn entspannt die Spiralfeder 41 und vermindert die Federkraft, Verschiebung nach hinten verstärkt sie.The spiral spring 41, which, as mentioned, on the support ring 40 is supported on the intermediate wall 25 of the holder 21, exercises a via the adjusting nut 37 on the pre-gripper 18 Force acting from the feed direction. The pre-gripper 18 is therefore in the retracted position shown in FIG. 2 of the slider 16 advanced so far relative to the same, as the driver ring 42 allows. Pushes the pre-gripper 18 when feeding on a test resistor, so it is against the bracket 21 against the force of the coil spring 41 retractable. The spring force is adjustable because the Adjusting nut 37 by rotating the bolt 36 by means of a at the front end attached screwdriver in Feed direction can be shifted. Shift of Setting nut 37 forward relaxes the spiral spring 41 and reduces the spring force, displacement to the rear reinforces it.

Die Anschlagmutter 43, deren Durchmesser grösser ist als die Breite des Schlitzes 33, bildet mit der Rückseite des Balken 32 einen Vorgreiferanschlag, welcher den Vorschub des Vorgreifers 18 beschränkt. Wenn der Vorschub des Schiebers 16 diesen Punkt erreicht hat, welcher durch Drehen der Anschlagmutter 43 und entsprechende Längsverschiebung derselben am Bolzen 36 einstellbar ist, setzt daher eine Relativbewegung zwischen dem Schieber 16 und der Halterung 21 einerseits und dem Vorgreifer 18 andererseits ein.The stop nut 43, the diameter of which is larger than that Width of the slot 33, forms with the back of the bar 32 a pre-gripper stop, which advances the Claw 18 limited. When the slide feeds 16 has reached this point, which is achieved by turning the Stop nut 43 and corresponding longitudinal displacement the same on the bolt 36 is adjustable, therefore sets one Relative movement between the slider 16 and the bracket 21 on the one hand and the pre-gripper 18 on the other.

Das Vorgreifergehäuse 34 weist nun an seiner Unterseite ein im wesentlichen in Vorschubrichtung verlaufendes Profil 44 auf mit einem zur Vorschubrichtung parallelen ersten Profilabschnitt 45 sowie weiter vorn einem gleichartigen, aber bezüglich des Schiebers 16 etwas höher liegenden zweiten Profilabschnitt 46, welche durch einen nach unten weisenden Zacken 47 getrennt sind. Das Profil 44 wird durch eine an der Unterseite des Schiebers 16 befestigte Andrückfeder 48, welche als Blattfeder ausgebildet ist und gleitend gegen die Oberseite des Vorgreifergehäuses 34 drückt, an eine am unteren Rand der Ausnehmung 24 in der Vorderwand 23 des Vorgreifergehäuses 34 angeordnete nach oben weisende Nase 49 angedrückt. Die Nase 49 kann von einem mit der Vorderwand 23 verschraubten abriebfesten Austauschteil gebildet werden und z. B. aus Messing bestehen. Sie ist durch eine mittige Ausnehmung zweigeteilt. Die Kraft der Andrückfeder 48 ist mittels einer Einstellschraube 50 regelbar. Die Wechselwirkung zwischen dem Profil 44 und der Nase 49 regelt die Höhenposition des Vorgreifers 18 gegenüber dem Schieber 16 während des letzten Abschnitts des Vorschubs des letzteren. Wie weiter unten noch näher erläutert werden wird, ist der Vorgreifer 18 so in der Halterung 21 geführt, dass er, nachdem er erst parallel mit dem Schieber 16 vorgeschoben wurde, am Ende seiner Vorschubbewegung angehoben und dann wieder auf eine Position abgesenkt wird, die mindestens der vor dem Anheben eingenommenen entspricht und vorzugsweise etwas tiefer ist.The pre-gripper housing 34 now has on its underside Profile 44 running essentially in the feed direction on with a first parallel to the feed direction Profile section 45 and further ahead a similar, but are somewhat higher with respect to the slider 16 second profile section 46, which by a down pointing prongs 47 are separated. The profile 44 is by one attached to the underside of the slider 16 Pressure spring 48, which is designed as a leaf spring and sliding against the top of the pre-gripper housing 34 presses to one at the bottom of the recess 24 in the Front wall 23 of the pre-gripper housing 34 arranged after nose 49 pressed above. The nose 49 can be from one abrasion-resistant screwed to the front wall 23 Exchange part are formed and z. B. made of brass consist. It is divided into two by a central recess. The force of the pressure spring 48 is by means of a Adjustable screw 50 adjustable. The interaction between the profile 44 and the nose 49 regulates the height position of the Gripper 18 against the slider 16 during the last Section of the feed of the latter. As below will be explained in more detail, the pre-gripper 18 is so guided in the bracket 21 that he, after he was advanced in parallel with the slide 16, at the end its feed motion is raised and then back to one Position is lowered, which is at least that before lifting taken corresponds and is preferably somewhat deeper.

Die Abzugseinrichtung 8 weist (s. auch Fig. 3) zwei Klemmelemente auf, welche als Scheibensegmente 51a,b ausgebildet sind. Sie sind an einer gemeinsamen angetriebenen Welle 52 befestigt. Die teilzylindrischen äusseren Abschnitte der Scheibensegmente 51a,b bilden eine Klemmfläche 53, welche einseitig von einer Hebekante 54 begrenzt wird. An der Innenseite sind die Scheibensegmente 51a,b anschliessend an die Hebekante 54 etwas gekehlt. Die Klemmfläche 53 wirkt mit einem als Klemmwalze 55 ausgebildeten Gegenelement zusammen, welches oberhalb der Scheibensegmente 51a,b parallel zur Welle 52 in einer schwenkbaren Halterung 56 drehbar gelagert ist. Die Halterung 56 ist mittels einer Spiralfeder 57 mit einer elastischen Kraft beaufschlagt, welche mittels einer Rändelmutter 58 einstellbar ist und die Klemmwalze 55 gegen die Scheibensegmente 51a,b drückt. Ausserdem ist ein Schalter 59 vorgesehen, der, wenn der Abstand zwischen der Klemmwalze 55 und den Klemmelementen 51a,b einen Grenzwert erreicht, von der Halterung 56 betätigt anspricht und die Stanzvorrichtung anhält. Auf diese Weise können Störungen des Papiertransports wie z. B. Papierstaus in der Transporteinrichtung 9 vermieden werden. Der Grenzwert des Schalters 59 kann einstellbar sein.The trigger device 8 has two (see also FIG. 3) Clamping elements, which act as disc segments 51a, b are trained. You are at a common driven shaft 52 attached. The partially cylindrical outer sections of the disk segments 51a, b form a Clamping surface 53, which is on one side of a lifting edge 54 is limited. The disc segments are on the inside 51a, b then slightly raised to the lifting edge 54. The The clamping surface 53 acts as a clamping roller 55 trained counter element together, which above the Disc segments 51a, b parallel to shaft 52 in one pivotable bracket 56 is rotatably mounted. The Bracket 56 is by means of a spiral spring 57 with a applied elastic force, which by means of a Knurled nut 58 is adjustable and the pinch roller 55 against the disc segments 51a, b presses. In addition, is a Switch 59 provided the when the distance between the Pinch roller 55 and the clamping elements 51a, b a limit reached, actuated by the holder 56 and the Punching device stops. This can cause glitches of paper transport such as B. paper jams in the Transport device 9 can be avoided. The limit of the Switch 59 can be adjustable.

Die Welle 52 trägt weiter aussen Hebeelemente 60a,b, welche im wesentlichen den Scheibensegmenten 51a,b entsprechend ausgebildet, jedoch ihnen gegenüber um gegen 90° entgegen der Drehrichtung der Welle 52 versetzt sind, so dass ihre Hebekanten 54 denjenigen der Scheibensegmente 51a,b nachlaufen.The shaft 52 further carries lifting elements 60a, b, which essentially corresponding to the disk segments 51a, b trained, but opposite them by about 90 ° the direction of rotation of the shaft 52 are offset so that their Lifting edges 54 those of the disc segments 51a, b run after.

Die Transporteinrichtung 9 weist im Bereich der Abzugseinrichtung 8 zwei an einer gemeinsamen angetriebenen Welle 61 angebrachte Rollen 62a,b auf, über welche jeweils flache Transportriemen 63a,b laufen, die das erste Riemenpaar 10a (Fig. 1a,b) bilden, ausserdem zwei weitere an einer weiteren angetriebenen Welle 64 befestigte Rollen 65a,b, über welche Transportriemen 66a,b runden Querschnitts geführt sind, die das zweite Riemenpaar 10b bilden. Unterhalb der Rollen 65a,b sind zwei Führungsrollen 67a,b an einer federnd gelagerten Welle 68 vorgesehen.The transport device 9 has in the area of Trigger device 8 two driven on a common Shaft 61 attached rollers 62a, b, over each of which flat conveyor belts 63a, b run which are the first Belt pair 10a (Fig. 1a, b) also form two more another driven shaft 64 attached rollers 65a, b, via which transport belts 66a, b round cross-section are guided, which form the second pair of belts 10b. Below the rollers 65a, b are two guide rollers 67a, b a spring-mounted shaft 68 is provided.

Die Wirkungsweise des oben beschriebenen Teils der Stanzvorrichtung wird im folgenden vor allem anhand der Fig. 4a-f erklärt, in denen z. T. zur Erleichterung des Ueberblicks für das Verständnis nicht notwendige Teile - abhängig vom dargestellten Stadium des Verfahrens - weggelassen wurden:The operation of the part of the above described The punching device is described below, primarily with reference to FIG. 4a-f explains in which e.g. T. to facilitate the Overview of parts not necessary for understanding - depending on the stage of the procedure presented - were omitted:

Aus der in Fig. 2 dargestellten Position wird die Halterung 21 zusammen mit dem Schieber 16 durch Drehung der Kurbel 30 vorgeschoben, wobei der Vorgreifer 18 mitgenommen wird und mit der Schneidkante seines Schnabels 19 in den Vorratsstapel 4 einsticht und so ein Bündel 69 von einem Reststapel 70 trennt. Der Einstich wird durch die gefederte Führung des Vorgreifers 18 in der Halterung 21 etwas gedämpft. Zugleich erreicht die Anschlagmutter 43 den Balken 32. Der Vorgreiferanschlag wird wirksam und verhindert, dass der Vorgreifer 18 beim weiteren Vorschub des Schiebers 16 mitgenommen wird (Fig. 4a).From the position shown in Fig. 2, the bracket 21 together with the slide 16 by turning the crank 30 advanced, the pre-gripper 18 is taken along and with the cutting edge of his beak 19 in the Stack of sticks 4 and so a bundle 69 of one Remaining stack 70 separates. The puncture is spring-loaded Guiding the pre-gripper 18 in the holder 21 somewhat subdued. At the same time, the stop nut 43 reaches the beam 32. The pre-gripper stop takes effect and prevents the pre-gripper 18 as the slide 16 is advanced is taken along (Fig. 4a).

Beim weiteren Vorschub gleitet daher die Nase 49 am ersten Abschnitt 45 des Profils 44 an der Unterseite des Vorgreifergehäuses 34 entlang und stösst schliesslich an den Zacken 47, was eine rasche Anhebung des Vorgreifers 18 bewirkt. Er hebt dabei gleichzeitig den der Schubeinrichtung 5 zugewandten Randbereich des Bündels 69 von Blättern am oberen Ende des Vorratsstapels 4 etwas an, so dass der Rand desselben - im folgenden Gegenrand 71 genannt - von der Stossfläche 17 des Schiebers 16, welcher über den Vorratsstapel 4 vorgeschoben wird und in diesem Moment den Vorgreifer 18 einholt, erfasst wird (Fig. 4b).With further advance, the nose 49 therefore slides on the first one Section 45 of the profile 44 at the bottom of the Vorackerergehäuses 34 and finally comes up against the Prongs 47, which means that the pre-gripper 18 is raised quickly causes. At the same time, it lifts that of the pusher 5 facing edge region of the bundle 69 of leaves on top of the supply stack 4 slightly so that the edge the same - hereinafter called the opposite edge 71 - from the Butt surface 17 of the slider 16, which over the Storage stack 4 is advanced and at that moment Pre-gripper 18 catches up, is detected (Fig. 4b).

Wird, etwa zur Bearbeitung von Karton, der Schnabel 19' eingesetzt, so wird die Federung des Vorgreifers 18 mittels der Einstellmutter 37 verhältnismässig weich eingestellt, derart, dass die Stirnfläche 20', wenn sie seitlich an den Vorratsstapel 4 anstösst, nicht eindringt, aber angedrückt wird, so dass beim Anheben des Vorgreifers 18 der Gegenrand eines Bündels durch Reibung mitangehoben wird.If, for example, for processing cardboard, the beak 19 ' used, the suspension of the pre-gripper 18 is by means of the adjusting nut 37 is set relatively soft, such that the end face 20 'when it is laterally connected to the Stack of 4 pushes, does not penetrate, but is pressed becomes, so that when the pre-gripper 18 is raised, the opposing edge a bundle is also lifted by friction.

Beim weiteren Vorschub wird die Nase 49 über den Zacken 47 hinaus geschoben, so dass der Vorgreifer 18 von der Andrückfeder 48 wieder nach unten gedrückt wird und eine geringfügig tiefere Position einnimmt als vor dem Anheben. Er liegt dadurch mit der Unterseite des Schnabels 19 auf dem obersten Blatt des Reststapels 70 auf und klemmt dasselbe fest, so dass keine Blätter des Reststapels 70 mitgezogen werden, wenn das Bündel 69 durch weiteren Vorschub des Schiebers 16 derart versetzt wird, dass sein zu bearbeitender Randbereich 72 in die Stanzeinrichtung 6 zu liegen kommt, während der verbleibende Teil des Bündels 69 überwiegend auf dem Reststapel 70 aufliegt (Fig. 4c).As the feed continues, the nose 49 becomes over the prongs 47 pushed out so that the pre-gripper 18 from the Pressure spring 48 is pressed down again and one takes a slightly lower position than before lifting. It lies with the underside of the beak 19 on the top sheet of the remaining stack 70 and clamps the same firmly so that no sheets of the remaining stack 70 are pulled along be when the bundle 69 by further feeding the Slider 16 is offset so that its to machining edge area 72 into the punching device 6 lies while the remaining part of the bundle 69 predominantly rests on the remaining stack 70 (FIG. 4c).

Während mittels der Stempel 7 Löcher in den Randbereich 72 gestanzt werden, greifen die gleichmässig im Gegenuhrzeigersinn rotierenden Scheibensegmente 51a,b der Abzugseinrichtung 8 mit den Hebekanten 54 unter den Gegenrand 71 des versetzten Bündels 69 und heben den daran anschliessenden Bereich desselben weiter an (Fig. 4d).While 7 holes are made in the edge area 72 by means of the stamp are punched, they grip evenly in the Counterclockwise rotating disc segments 51a, b of the Trigger device 8 with the lifting edges 54 under the Opposing edge 71 of the offset bundle 69 and lift it subsequent area of the same on (Fig. 4d).

Während die Stempel 7 zurückgezogen werden, wird der an den Gegenrand 71 anschliessende Bereich des bearbeiteten Bündels 69 von der Hebekante 54 bis zur Klemmwalze 55 gehoben und zwischen derselben und der an die Hebekante 54 anschliessenden Klemmfläche 53 der Scheibensegmente 51a,b geklemmt und so das Bündel 69 abgezogen und entgegen der Versetzungsrichtung der Transporteinrichtung 9 zugeführt (Fig. 4e). Die Eckbereiche des Bündels 69 werden etwas später als die Mitte des Gegenrandes 71 von den Hebeelementen 60a,b (Fig. 2) erfasst, welche so das Anheben des Bündels 69 unterstützen. Durch weitere Drehung der Kurbel 30 wurde währenddessen der Schieber 16 zurückgezogen, wobei, sobald die Zwischenwand 25 den Anschlagring 42 erreichte, der Mitnehmeranschlag wirksam und der Vorgreifer 18 mitgezogen wurde.While the stamps 7 are withdrawn, the stamp is sent to the Opposing edge 71 adjoining area of the processed bundle 69 raised from the lifting edge 54 to the pinch roller 55 and between the same and that on the lifting edge 54 subsequent clamping surface 53 of the disc segments 51a, b clamped and thus pulled the bundle 69 and against the Direction of displacement of the transport device 9 supplied (Fig. 4e). The corner areas of the bundle 69 become something later than the center of the opposite edge 71 of the Lifting elements 60a, b (Fig. 2) detected, which thus the lifting of bundle 69 support. By further turning the Crank 30, the slide 16 has been withdrawn, whereby as soon as the intermediate wall 25 the stop ring 42 reached, the driver stop effective and the pre-gripper 18 was pulled.

Bereits während das abgezogene Bündel 69 noch teilweise auf dem Reststapel 70 aufliegt, wird (Fig. 4f) der Vorratsstapel 4 mittels der Stapelauflage 3 (Fig. 1a,b) um eine Bündeldicke gehoben und ein weiteres Bündel 69' durch den wieder vorgeschobenen Vorgreifer 18 im Bereich des Gegenrandes 71 angehoben und durch die Stossfläche 17 des Schiebers 16 verschoben, so dass sein zu bearbeitender Randbereich 72 in die Stanzeinrichtung 6 ragt, womit das Bündel 69' eine der des Bündels 69 in Fig. 4c entsprechende Position erreicht hat.Already during the withdrawn bundle 69 still partially open rests on the remaining stack 70, the supply stack becomes (FIG. 4f) 4 by means of the stack support 3 (Fig. 1a, b) Bundle thickness lifted and another bundle 69 'through the again advanced pre-gripper 18 in the area of Counter edge 71 raised and by the abutment surface 17 of the Slider 16 moved so that its to be machined Edge region 72 protrudes into the punching device 6, which means that Bundle 69 'corresponds to that of bundle 69 in FIG. 4c Has reached position.

Es sei in diesem Zusammenhang darauf hingewiesen, dass in Fig. 4a-f zwecks Vermeidung einer Ueberladung der Figuren der Beginn der Bearbeitung dargestellt ist. Andernfalls wären auch einige der vor dem Bündel 69 bearbeiteten Bündel sichtbar.In this context it should be noted that in 4a-f in order to avoid overloading the figures the beginning of the processing is shown. Otherwise would also be some of the bundles processed before bundle 69 visible.

Aufeinanderfolgende Bündel 69, 69' werden in einem Abstand, der deutlich geringer ist als die Bündelbreite, durch die Abzugseinrichtung 8 abgezogen und der Transporteinrichtung 9 zugeführt, wo sie zuerst zwischen den Transportriemen 66a,b einerseits und den Führungsrollen 67a,b andererseits und in der Folge zwischen den ersteren und den Transportriemen 63a,b geklemmt und schuppenartig überlappend zum Zielstapel 13 transportiert werden. Dabei werden die Bündel 69 zur Beibehaltung der Blattreihenfolge gewendet. Durch die Klemmung zwischen den Transportriemen 66a,b und den etwas versetzten Führungsrollen 67a,b eingangs der Transporteinrichtung 9 werden die einzelnen Blätter eines Bündels jeweils etwas gegeneinander verschoben, wodurch die durch das Stanzen oft ziemlich starke Haftung zwischen unmittelbar aufeinanderliegenden Blättern gelöst wird.Successive bundles 69, 69 'are spaced which is significantly smaller than the bundle width through which Trigger device 8 is withdrawn and the transport device 9 fed where they first between the conveyor belts 66a, b on the one hand and the guide rollers 67a, b on the other hand and in the sequence between the former and the conveyor belts 63a, b clamped and overlapping like scales to the target stack 13 can be transported. The bundles 69 become Maintaining the sheet order turned. Through the Clamp between the conveyor belts 66a, b and the something offset guide rollers 67a, b at the beginning of the Transport device 9, the individual sheets one Bundles each shifted slightly against each other, whereby the through punching often quite strong adhesion between immediately lying sheets is solved.

Die beschriebene Art des Abzugs aus dem Bearbeitungsbereich und des Transports können zusammen oder für sich genommen auch bei erfindungsgemässen Verfahren, bei denen die Abfolge der Schritte eine andere ist als oben dargestellt oder die Versetzung der zu bearbeitenden Bündel auf eine andere Weise erfolgt sowie auch bei weiteren gattungsgemässen Verfahren und Vorrichtungen, insbesondere Stanz- oder Prägevorrichtungen, mit Gewinn angewandt werden. Andererseits kann auch die Art der Versetzung von Bündeln gegenüber dem verbleibenden Reststapel in anderem Zusammenhang, insbesondere einem anderen Ablauf der Verfahrensschritte, angewandt werden. Die geschilderte Kombination ist jedoch äusserst günstig in Bezug auf Raschheit und Zuverlässigkeit der Bearbeitung und Kompaktheit der Vorrichtung.The described type of deduction from the processing area and transportation can be taken together or on their own also in the case of methods according to the invention in which the sequence the steps are different from the ones shown above or the Moving the bundles to be processed in a different way takes place and also in other generic methods and devices, in particular punching or Embossing devices to be applied at a profit. On the other hand, the type of transfer of bundles can also compared to the remaining batch in another Context, in particular a different process of Process steps are applied. The one described However, combination is extremely cheap in terms of Speed and reliability of processing and Compactness of the device.

Die Stanzeinrichtung 6 umfasst (Fig. 5a,b, 6) einen Träger 73, in welchem die Stempel 7 gehaltert sind. Eine Führung 74 und eine Matrize 75, welche zwischen sich einen Spalt 76 zur Aufnahme der zu bearbeitenden Randbereiche 72 von Bündeln 69 bilden, weisen Bohrungen 77 bzw. 78 zur Aufnahme der Stempel 7 auf. An der dem Vorratsstapel 4 abgewandten Seite ist der Spalt 76 durch einen einstellbaren Anschlag begrenzt. Er wird von Fingern eines verschiebbaren Einstellbalken 79 gebildet, die in den Spalt 76 ragen. Der Träger 73 ist mit einer Halterung 80 verschraubt, welche in einer Gleitführung 81 quer zum Spalt 76 verschiebbar gelagert ist.The punching device 6 comprises (FIGS. 5a, b, 6) a carrier 73, in which the stamp 7 are held. A guide 74 and a die 75, which has a gap 76 between them Recording of the edge areas 72 to be processed by bundles 69 form, have holes 77 and 78 for receiving the stamp 7 on. On the side facing away from the stack 4 is the Gap 76 limited by an adjustable stop. He is by fingers of a sliding adjustment bar 79th formed, which protrude into the gap 76. The carrier 73 is with a bracket 80 screwed, which in a sliding guide 81 is slidably mounted transversely to the gap 76.

Zum Antrieb der Stanzvorrichtung 6 ist eine intermittierend drehende Welle 82 vorgesehen, welche zwei Antriebsteile trägt, die als eiförmige Antriebsscheiben 83a,b ausgebildet sind und jeweils an der der anderen Antriebsscheibe zugewandten Innenseite eine geschlossenen Antriebsnut 84 tragen, welche die Welle 82, der Randlinie der jeweiligen Antriebsscheibe folgend, in wechselndem Abstand umgibt. In die Antriebsnuten 84 greifen parallel zur Welle 82 von Laschen 85a,b an der Oberseite der Halterung 80 abragende Rollen 86 ein.One is intermittent for driving the punching device 6 rotating shaft 82 provided which two drive parts carries, which are designed as egg-shaped drive disks 83a, b are and each on the other drive pulley facing inside a closed drive groove 84th wear which the shaft 82, the edge line of the respective Following the drive pulley surrounds at an alternating distance. In the drive grooves 84 engage parallel to the shaft 82 Tabs 85a, b protruding from the top of the bracket 80 Roll 86.

Ausgehend von der Grundstellung (Fig. 5a), in welcher sich die Stempel 7 in ihrer oberen Grenzposition befinden - die Schubeinrichtung 5 nimmt die in Fig. 2 dargestellte zurückgezogene Position ein - wird, nachdem in der im Zusammenhang mit den Fig. 4a-c beschriebenen Weise der Randbereich 72 eines Bündels 69 von zu bearbeitenden Blättern in den Spalt 76 geschoben wurde, die Welle 82 gedreht und die Rollen 86 jeweils durch die nockenartige Ausbuchtung der Innenwand der Antriebsnut 84 nach unten gedrückt. Dies zieht eine entsprechende Bewegung der Halterung 80, des Trägers 73 und der Stempel 7 nach sich, so dass die letzteren den im Spalt 76 liegenden Randbereich 72 des Bündels 69 durchstossen und ihre untere Grenzposition erreichen (Fig. 5b). Starting from the basic position (Fig. 5a), in which the stamps 7 are in their upper limit position - the Thrust device 5 takes the one shown in FIG. 2 retracted position - will be after in the im Connection with the Fig. 4a-c described the Edge region 72 of a bundle 69 of those to be processed Scroll was pushed into the gap 76, the shaft 82 rotated and the rollers 86 each by the cam-like Bulge of the inner wall of the drive groove 84 downwards pressed. This draws a corresponding movement of the Bracket 80, the carrier 73 and the stamp 7 itself, so that the latter the edge region 72 lying in the gap 76 of the bundle 69 pierced and its lower limit position reach (Fig. 5b).

Durch weitere Drehung der Welle 82 werden die Rollen 86 jeweils durch die Aussenwand der Antriebsnut 84 angehoben. Der Rückzug der Stempel 7 in ihre obere Grenzposition wird somit durch die Bewegung der Welle 82 erzwungen. Das Bündel 69 kann nun wie im Zusammenhang mit Fig. 4d-f erläutert zurückgezogen werden.By further rotation of the shaft 82, the rollers 86 each raised by the outer wall of the drive groove 84. The retraction of the stamp 7 in its upper limit position will thus forced by the movement of the shaft 82. The bundle 69 can now as explained in connection with Fig. 4d-f be withdrawn.

Ein ebenfalls den Rückzug der Stempel 7 erzwingender, einfacherer, aber weniger genau steuerbarer Antrieb kann mit als Kurbeln ausgebildeten Antriebsteilen erzielt werden, welche mit der Halterung über beidseits drehbar verankerte Pleuel verbunden sind.A also the retraction of the stamp 7, simpler, but less precisely controllable drive can be used drive parts designed as cranks can be achieved, which anchored to the bracket via rotatable on both sides Connecting rods are connected.

In jedem Fall kann die gleiche Antriebsart natürlich auch in Prägevorrichtungen verwendet werden, welche überhaupt, von der unterschiedlichen Ausbildung der Stempel 7 abgesehen, praktisch genau gleich aufgebaut sein können, desgleichen im Zusammenhang mit Verfahren und Vorrichtungen, insbesondere zum Stanzen oder Prägen, in denen der Ablauf der Bearbeitung oder Versetzung und Transport der Bündel auf andere Weise als weiter oben dargestellt gelöst ist.In any case, the same type of drive can of course also be used in Embossing devices are used, which, at all apart from the different design of the stamp 7, can be constructed practically exactly the same, as in Relation to methods and devices, in particular for punching or embossing, in which the processing sequence or moving and transporting the bundles in another way is solved as shown above.

Die beschriebenen Vorgänge laufen durchwegs automatisch ab. Die sehr kurzen Wege, die ein Bündel vom Vorratsstapel zur Bearbeitung und beim Rückzug aus der Bearbeitungseinrichtung zurücklegt, um dieselbe für das nächste Bündel freizumachen, erlauben eine Bearbeitungsfrequenz, die mindestens 50% über denjenigen bekannter gattungsgemässer Vorrichtungen liegt.The processes described are carried out automatically throughout. The very short distances that a bundle from the stockpile to Processing and when withdrawing from the processing facility to clear it for the next bundle, allow a machining frequency that is at least 50% above those of known generic devices.
