Description

Die Erfindung betrifft eine Vorrichtung zum Überführen einer Drahtkammbindung aus einer ersten in eine zweite Position mit einer ersten, die Drahtkammbindung für die Überführung bereithaltenden Station, einer zweiten, die Drahtkammbindung aufnehmenden Station, einer die erste und die zweite Station verbindenden Förderstrecke und Überführungsmitteln zum queraxialen Bewegen der Drahtkammbindung aus der ersten Station über die Förderstrecke in die zweite Station, wobei während der Bewegung der Drahtkammbindungen aus der ersten in die zweite Station eine Änderung der Winkellage der Drahtkammbindung bezüglich ihrer Längsachse erfolgt.The invention relates to a device for transferring a wire comb binding from a first to a second position with a first, the wire comb binding for the transfer ready station, a second, the wire comb binding receiving station, a connecting the first and the second station Conveyor line and transfer means for moving the wire comb binding transversely axially from the first station via the conveyor line to the second station, whereby during the movement of the wire comb bindings from the first into the second station regarding a change in the angular position of the wire comb binding their longitudinal axis.

Das Verbinden von zu Stapeln aufgeschichteten Blättern aus Papier oder der gleichen, die an einem Rand entlang perforiert sind, zu Heften oder Blöcken durch Einsetzen von Drahtkammbindungen ist seit langem bekannt. Hierzu wird aus einem endlosen Draht zunächst ein endloser Drahtkamm gebildet, der C-förmig geformt wird. Von diesem C-förmig geformten Drahtkamm werden für jeden zu bindenden Blattstapel ein oder mehrere Drahtkammabschnitte, sogenannte Drahtkammbindungen, abgeschnitten. Bei einer derartigen Vorrichtung nach dem Stand der Technik wird jede Drahtkammbindung auf einen mit einem Magneten versehenen Halter geschoben und dann durch Schwenken des Halters um eine parallel zu ihrer Längsachse verlaufende Schwenkachse in eine Bindestation geschwenkt. Dort wird die Drahtkammbindung mittels einer Zange in die Perforierung des Blattstapels eingeführt und geschlossen (DE 24 03 154 C3). Jeder Blattstapel kann mit einer einzigen Drahtkammbindung passender Länge oder - bei der sogenannten Skip-Bindung - mit mehreren beabstandeten kürzeren Drahtkammbindungen gebunden werden (DE 31 41 686 C2). Die C-förmigen Drahtkammbindungen können auch zunächst an Tragleisten oder Tragbändern aufgereiht und so zu Matten zusammengefaßt werden. In dieser Form können sie gelagert und transportiert werden, um später ihrer Verwendung zum Binden von Blattstapeln zugeführt zu werden (GB-PS 987 117, GB 2 257 070 A).Joining sheets of paper or paper stacked up in stacks same, which are perforated along an edge, through to booklets or blocks Inserting wire comb bindings has been known for a long time. This is done from an endless wire, an endless wire comb is first formed, which is C-shaped is formed. This C-shaped wire comb will be bound for everyone Sheet stack one or more wire comb sections, so-called Wire comb bindings, cut off. In such a device according to the State of the art, each wire comb binding on one with a magnet provided holder and then by pivoting the holder by one parallel to its longitudinal axis pivot axis in a binding station pivoted. There the wire comb binding is inserted into the perforation using pliers the sheet stack inserted and closed (DE 24 03 154 C3). Every stack of sheets can with a single wire comb binding of appropriate length or - at the so-called skip binding - with several shorter ones spaced apart Wire comb bindings are bound (DE 31 41 686 C2). The C-shaped Wire comb bindings can also initially on support strips or support straps lined up and combined into mats. In this form they can be stored and transported for later use for binding Sheet stacks to be fed (GB-PS 987 117, GB 2 257 070 A).

In vielen Fällen ist es erforderlich, die Drahtkammbindungen nach dem Abschneiden vom endlosen Drahtkamm in eine für die gewünschte weitere Verarbeitung geeignete Lage und Ausrichtung zu bringen. Gemäß der DE 24 03 154 C3 und der GB 1 209 940 geschieht dies mittels eines Schwenkarms, der die Drahtkammbindungen nacheinander auf einer Kreisbahn entlang bewegt und dabei um 90° schwenkt. Das erfordert größeren konstruktiven Aufwand und Bauraum in der Maschine.In many cases, it is necessary to remove the wire comb bindings after cutting them off from the endless wire comb into one for the desired further processing bring appropriate location and orientation. According to DE 24 03 154 C3 and GB 1 209 940 this is done by means of a swivel arm that binds the wire combs successively moved along a circular path and thereby by 90 ° pivots. This requires greater design effort and space in the Machine.

Der Erfindung liegt die Aufgabe zugrunde, eine weitere Vorrichtung der eingangs beschriebenen Art anzugeben.The invention has for its object a further device of the beginning Specify the type described.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß wenigstens ein Abschnitt der Förderstrecke als Gleitbahn ausgebildet ist, daß die Überführungsmittel einen Schieber aufweisen, welcher die Drahtkammbindung queraxial entlang der Gleitbahn verschiebt und daß die Gleitbahn als Mittel zum Ändern der Winkellage der Drahtkammbindung einen Streckenabschnitt mit Mitteln zum Ausüben einer einseitigen Rückhaltekraft auf die Drahtkammbindung aufweist, welche zusammen mit der die Drahtkammbindung über die Gleitbahn bewegenden Kraft des Schiebers ein die Winkellage der Drahtkammbindung veränderndes Kippmoment bewirkt.According to the invention, this object is achieved in that at least one section the conveyor track is designed as a slideway that the transfer means have a slider, which the wire comb binding transverse axially along the Slideway moves and that the slideway as a means of changing the angular position the wire comb binding a route section with means for exercising one-sided retention force on the wire comb binding, which together with the force of the slide moving the wire comb binding over the slideway causes a tilting moment that changes the angular position of the wire comb binding.

Gemäß der Erfindung ist die Förderstrecke also als im wesentlichen geradlinige Gleitbahn ausgebildet, über welche die Drahtkammbindung queraxial geschoben wird und auf der die Veränderung der Winkellage der Drahtkammbindungen während ihrer Bewegung entlang der Förderstrecke gemäß der Erfindung bewerkstelligt wird.According to the invention, the conveyor line is therefore essentially straight Slideway formed over which the wire comb binding is pushed transversely axially and the change in the angular position of the wire comb bindings accomplished during their movement along the conveyor line according to the invention becomes.

Weitere Fortführungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 5 enthalten. Dabei betrifft Anspruch 2 eine besonders bevorzugte Variante. Hiernach wird einfach mit Hilfe eines Magnetfeldes eine Rückhaltekraft auf die Drahtkammbindungen ausgeübt, die zusammen mit der Schubwirkung des Schiebers das für die Drehung erforderliche Kippmoment an der Drahtkammbindung bewirkt. Für nichtmagnetische Drahtkammbindungen sind die Maßnahmen nach dem Anspruch 3 vorgesehen. Die Merkmale der Ansprüche 4 und 5 betreffen Maßnahmen zum Begrenzen der Kippbewegung der Drahtkammbindungen in der Förderstrecke, die sicherstellen, daß die Drahtkammbindungen tatsächlich die vorgesehene Winkelorientierung erreichen und einhalten.Further developments and advantageous embodiments of the invention are in the Subclaims 2 to 5 included. Claim 2 is particularly relevant preferred variant. After that, simply with the help of a magnetic field Retaining force exerted on the wire comb bindings, which together with the Thrust effect of the slide the tilting moment required for the rotation on the Wire comb binding causes. For non-magnetic wire comb bindings they are Measures provided according to claim 3. The features of claims 4 and 5 relate to measures to limit the tilting movement of the wire comb bindings in the conveyor line which ensure that the wire comb bindings actually achieve and maintain the intended angular orientation.

Die Erfindung bietet den Vorteil, daß von einem C-förmigen Drahtkamm abgetrennte Drahtkammbindungen ohne großen Aufwand bezüglich ihrer Achse in eine neue Winkelposition gekippt werden. Das geschieht im engen Bereich einer ohnehin erforderlichen Förderstrecke, so daß die Änderung der Winkelposition keinen zusätzlichen Bauraum in der Maschine beansprucht. Die für die Änderung der Winkelposition eingesetzten Mittel sind einfach und kostengünstig und dabei weitgehend verschleiß- und wartungsfrei. Besonders einfach und wirksam ist die Vorrichtung für Drahtkammbindungen aus ferromagnetischem Draht zu verwenden, weil dabei die Kippbewegung allein durch das Feld eines oder mehrerer Magneten bewirkt wird. Aber auch unmagnetische Drahtkammbindungen können gemäß der Erfindung auf ähnlich einfache Weise beim Quertransport in eine neue Winkelposition gekippt werden. The invention has the advantage that separated from a C-shaped wire comb Wire comb bindings with little effort regarding their axis in one new angular position can be tilted. That happens in the narrow area anyway required conveyor line, so that the change in the angular position is none additional space is required in the machine. The one for changing the Angular position means are simple and inexpensive and largely wear and maintenance free. The device is particularly simple and effective to be used for wire comb bindings made of ferromagnetic wire, because the tilting movement occurs solely through the field of one or more magnets is effected. However, non-magnetic wire comb bindings can also be made according to the Invention in a similarly simple manner when transversely transporting to a new angular position be tilted.

Die Erfindung wird nun anhand der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the drawing.

In Figur 1 ist eine typische Drahtkammbindung 1 perspektivisch dargestellt. Es handelt sich dabei um einen Abschnitt vorgegebener Länge eines C-förmig gebogenen Drahtkammes. Die Drahtkammbindung weist an ihrer offenen Seite einander gegenüberliegend Spitzen 2 und Stege 3 auf. Mit 4 ist der Rücken der Drahtkammbindung bezeichnet.A typical wire comb binding 1 is in perspective in FIG shown. It is a section of predetermined Length of a C-shaped wire comb. The wire comb binding points opposite each other on its open side Tips 2 and webs 3. At 4 is the back of the wire comb binding designated.

Zum Binden eines Blattstapels werden die Spitzen 2 mittels einer Zange in entsprechende Perforationen der Blätter eingeführt, dann wird die Bindung geschlossen. Dieser Vorgang ist bekannt und nicht Gegenstand der vorliegenden Erfindung.To bind a sheet stack, the tips 2 are by means of a pair of pliers is inserted into corresponding perforations in the leaves, then the bond is closed. This process is known and not the subject of the present invention.

Figur 2 zeigt ein Ausführungsbeispiel der Vorrichtung nach der Erfindung in einer schematischen Vorderansicht. Diese Vorrichtung weist auf einem Gestell 6 eine erste Station 7 auf, in welcher die Drahtkammbindungen 1 nacheinander für die Weiterverarbeitung bereitgehalten werden. Diese erste Station 7 kann eine Schneidstation sein, in welche ein C-förmig gebogener Drahtkamm längsaxial vorgeschoben wird, von dem nacheinander die als Drahtkammbindung 1 vorgesehenen Abschnitte abgetrennt werden. Dieses längsaxiale Fördern des Drahtkammes erfolgt mittels eines Förderers 8, der an seiner Oberfläche Klammern 9 zum positionsgerechten Halten des Drahtkammes bzw. der abgetrennten Drahtkammbindungen 1 aufweist. Unter dem Förderer 8 ist ein Magnet 11 angeordnet, der Schwingungen des Drahtkammes bzw. der Drahtkammbindungen 1 verhindert.Figure 2 shows an embodiment of the device according to the Invention in a schematic front view. This device has a first station 7 on a frame 6, in which the wire comb bindings 1 in succession for further processing be kept ready. This first station 7 can be a cutting station into which a C-shaped curved Wire comb is advanced axially, one after the other the sections provided as wire comb binding 1 separated become. This longitudinal axial conveying of the wire comb takes place by means of a conveyor 8 which has clips 9 on its surface for holding the wire comb or the separated ones in the correct position Wire comb bindings 1. Under conveyor 8 a magnet 11 is arranged, the vibrations of the wire comb or the wire comb bindings 1 prevented.

Eine Förderstrecke 12 verbindet die erste Station 7 mit einer zweiten Station 13. Sie wird von einer Gleitbahn 14 mit aufgesetzten, in Förderrichtung verlaufenden Führungsleisten 16 gebildet. Unterhalb der Gleitbahn 14 ist ein Magnet 17 angeordnet. Quer zur Förderrichtung können nebeneinander auch mehrere solche Magneten 17 vorgesehen sein. Das Magnetfeld erstreckt sich in die Bewegungsbahn der Drahtkammbindung 1 entlang der Gleitbahn hinein. Die Gleitbahn ist hierzu für das Magnetfeld durchlässig. Ein Schieber 18 ist in Richtung eines Doppelpfeiles 19 in Förderrichtung parallel zur Gleitbahn 14 verschiebbar angeordnet, um in der ersten Station 7 bereitgestellte Drahtkammbindungen 1 über die Gleitbahn 14 zur zweiten Station 13 zu bewegen.A conveyor line 12 connects the first station 7 with one second station 13. It is by a slideway 14 with attached, guide strips 16 running in the conveying direction educated. A magnet 17 is arranged below the slideway 14. At the same time, several can also run parallel to the conveying direction such magnets 17 may be provided. The magnetic field extends into the path of movement of the wire comb binding 1 along the Slideway in. The slideway is for the magnetic field permeable. A slide 18 is in the direction of a double arrow 19 displaceable parallel to the slideway 14 in the conveying direction arranged to wire comb bindings provided in the first station 7 1 via the slideway 14 to the second station 13 move.

In der Förderstrecke 12 schließt sich an die Gleitbahn 14 die Vorderseite eines Stößels 21 an, die auf der Höhe der Gleitbahn liegt und mit den Führungsleisten 16 fluchtende Führungsleisten 22 trägt. Der Stößel 21 ist in Pfeilrichtung 23 senkrecht zur Förderstrecke 12 bewegbar angeordnet.In the conveyor section 12, the slideway 14 adjoins the Front of a plunger 21 at the level of the slide lies and with the guide strips 16 aligned guide strips 22 carries. The plunger 21 is perpendicular to the arrow 23 Conveyor track 12 is movably arranged.

Ein Endanschlag 24 ist aus einer vorgeschobenen ersten Position P1 (vgl. Figur 3) synchron mit dem die Drahtkammbindung auf der Gleitbahn bewegenden Schieber 18 in eine zurückgezogene zweite Position P2 (vgl. Figur 2) und zurück entsprechend einem Pfeil 26 verfahrbar. Die zweite Position P2 des Anschlags 24 definiert gleichzeitig das Ende der Förderstrecke 12 in Förderrichtung.An end stop 24 can be moved from an advanced first position P 1 (see FIG. 3) synchronously with the slide 18 moving the wire comb binding on the slideway to a retracted second position P 2 (see FIG. 2) and back according to an arrow 26. The second position P 2 of the stop 24 simultaneously defines the end of the conveying path 12 in the conveying direction.

Im Betrieb wird ein C-förmig gebogener Drahtkamm mittels des Förderers 8 längsaxial in die erste Station 7 vorgeschoben, wo ein Drahtkammabschnitt vorgegebener Länge von dem Drahtkamm abgetrennt wird. Dabei befindet sich der Schieber 18 in seiner zurückgezogenen Position und kann im Stegbereich 3 an der Drahtkammbindung anliegen. Der Anschlag 24 befindet sich in der zurückgezogenen Position P2 und die Oberfläche des Stößels 21 schließt mit der Gleitfläche fluchtend ab. Während nun die bereitgestellte Drahtkammbindung 1 vom Schieber 18 in Pfeilrichtung 19 nach links auf die Gleitbahn 14 der Förderstrecke 12 geschoben wird, wobei ihre seitliche Ausrichtung durch die Führungsleisten 16 gewährleistet bleibt, bewegt sich der Anschlag 24 in Pfeilrichtung 26 nach rechts in seine erste Position P1.In operation, a C-shaped wire comb is fed longitudinally axially into the first station 7 by means of the conveyor 8, where a wire comb section of a predetermined length is separated from the wire comb. The slider 18 is in its retracted position and can rest against the wire comb binding in the web area 3. The stop 24 is in the retracted position P 2 and the surface of the plunger 21 is flush with the sliding surface. While the wire comb binding 1 provided is now pushed from the slider 18 in the arrow direction 19 to the left onto the slideway 14 of the conveyor path 12, its lateral alignment being ensured by the guide strips 16, the stop 24 moves in the arrow direction 26 to the right into its first position P. 1st

Sobald die Orahtkammbindung 1 unter der Schubwirkung des Schiebers 18 den Magneten 17 erreicht, übt dessen Magnetfeld eine Rückhaltekraft auf die Drahtkammbindung aus, was unter der Wirkung der Schubkraft des Schiebers 18 zu einem Kippmoment führt, das eine Drehung der Drahtkammbindung in Richtung des Pfeiles 27 in Figur 3 bewirkt. Unter der Wirkung des Kippmomentes wird der Rücken 4 der Drahtkammbindung 1 von der Gleitfläche abgehoben, so daß sich die offene Seite der Drahtkammbindung entgegen dem Uhrzeigersinn zum Anschlag 24 hin verschwenkt. Zwei Winkelpositionen W1 und W2 dieses Schwenkvorganges sind in der Figur3 schematisch gezeigt. Dabei ist zu erkennen, daß unter der rückhaltenden Wirkung des Magnetfeldes des Magneten 17 auf die spitze Seite der Drahtkammbindung 1 ihr Rücken 4 von der Gleitfläche 14 abgehoben wird, so daß die Drahtkammbindung 1 gewissermaßen auf ihrer spitzen Seite abrollt und ihre offene Seite gegen den Anschlag 24 wendet. Diese Kippbewegung endet in dem Moment, in dem sowohl die Spitze als auch der Steg der Drahtkammbindung 1 an dem Anschlag 24 anliegen. Dies ist die Position W2 in Figur 3. Nun bewegen sich der Schieber 18 und der Anschlag 24 synchron in Pfeilrichtung 26 bzw. 19 nach links, wobei sie die Drahtkammbindung 1 in ihrer Position W2 zwischen sich festhalten. Dies ist in Figur 4 dargestellt. In Figur 5 hat der Anschlag 24 seine zurückgezogene zweite Position P2 erreicht, und der Schieber 18 ist bereits in seine Ausgangsposition zurückgekehrt, um der nächsten Drahtkammbindung in der ersten Station 7 Platz zu machen. Aus der zweiten Station 13 hat der Stößel 21 die Drahtkammbindung 1 an dem Anschlag 24 entlang in Pfeilrichtung 23 nach oben in Richtung auf die nächste Bearbeitungsstation verschoben. Dabei kann, was in der Zeichnung nicht dargestellt, aber üblich ist, die Drahtkammbindung 1 an eine Zange zum Einführen in die Perforation eines Papierstapels übergeben werden oder sie kann an einen Träger zum Bilden von Matten für die Bevorratung von vorbereiteten Drahtkammbindungen aufgereiht werden.As soon as the wire comb binding 1 reaches the magnet 17 under the pushing action of the slider 18, its magnetic field exerts a retaining force on the wire comb binding, which, under the action of the pushing force of the slider 18, leads to a tilting moment which causes the wire comb binding to rotate in the direction of arrow 27 in Figure 3 causes. Under the effect of the tilting moment, the back 4 of the wire comb binding 1 is lifted off the sliding surface, so that the open side of the wire comb binding pivots counterclockwise towards the stop 24. Two angular positions W 1 and W 2 of this pivoting process are shown schematically in FIG. It can be seen that under the restrained effect of the magnetic field of the magnet 17 on the pointed side of the wire comb binding 1, its back 4 is lifted off the sliding surface 14, so that the wire comb binding 1 rolls to a certain extent on its pointed side and its open side against the stop 24 turns. This tilting movement ends at the moment when both the tip and the web of the wire comb binding 1 rest against the stop 24. This is the position W 2 in FIG. 3. Now the slide 18 and the stop 24 move synchronously to the left in the direction of the arrow 26 and 19, respectively, holding the wire comb binding 1 in position W 2 between them. This is shown in Figure 4. In FIG. 5, the stop 24 has reached its retracted second position P 2 , and the slide 18 has already returned to its starting position in order to make room for the next wire comb binding in the first station 7. From the second station 13, the plunger 21 has shifted the wire comb binding 1 along the stop 24 in the direction of arrow 23 upward in the direction of the next processing station. What is not shown in the drawing, but is common, the wire comb binding 1 can be passed to a pair of pliers for insertion into the perforation of a paper stack or it can be lined up on a carrier for forming mats for the storage of prepared wire comb bindings.

Sofern die Drahtkammbindung nicht aus magnetischem Material besteht, kann anstelle eines Magneten 17 in der Förderstrecke die Reibung der Gleitbahn 14 partiell erhöht werden, wodurch ebenfalls eine Rückhaltekraft auf die Drahtkammbindung bewirkt werden kann, welche zu einer Drehung in der Drahtkammbindung im beschriebenen Sinne führt.Unless the wire comb binding is not made of magnetic material exists, can instead of a magnet 17 in the conveyor line the friction of the slideway 14 can be partially increased, whereby also causes a retention force on the wire comb binding can be, which leads to a rotation in the wire comb binding in the described sense leads.

Apparatus for transferring a wire comb binding from a first position to a second position, having a first station which holds the wire comb binding in readiness for the transfer, a second station which receives the wire comb binding, a conveying path which connects the first and the second station, and transfer means for moving the wire comb binding transversely to its axis from the first station by way of the conveying path to the second station, a change in the angular position of the wire comb binding (1) with respect to its longitudinal axis taking place during the movement of the wire comb bindings from the first station (7) to the second station (13), characterized in that at least a section of the conveying path (12) is constructed as a slideway (14), in that the transfer means include a pusher (18) which displaces the wire comb binding (1) transversely to its axis along the slideway and in that the slideway (14) includes, as the means for changing the angular position of the wire comb binding, a path section having means (17) for exerting a one-sided retaining force on the wire comb binding (1) which, together with the force of the pusher (18) moving the wire comb binding over the slideway (14), causes a tilting moment which changes the angular position of the wire comb binding.
  2. Apparatus according to Claim 1, characterized in that a magnet (17) aligned, beneath the slideway, with the movement path of the wire comb binding (1) is provided as the means for producing a retaining force.
  3. Apparatus according to Claim 1 or 2, characterized in that the slideway (14) includes a path section of increased friction as the means for changing the angular position of the wire comb binding.
  4. Apparatus according to one of Claims 1 to 3, characterized in that a stop (24) which is movable along the conveying path (12) and limits the tilting movement of the wire comb binding (1) is provided.
  5. Apparatus according to Claim 4, characterized in that the stop (24) is movable from an advanced first position (P1), in which it terminates the tilting movement of the wire comb binding (1), substantially synchronously with the pusher (18) moving the wire comb binding on the slideway (14), into a retracted second position (P2), in which the wire comb binding (1) tilted about its axis is transferred to a further conveyor (21).
