Abstract

In a paddle wheel for laying out folded products from a folding device, the aim is to match the paddle wheel pockets to the particular thickness of the printed products to be laid out. According to the invention, this is done by arranging a guide strip along each paddle, the strip at its end close to the pocket floor being capable of rising and falling along its entire width under the action of a drive.

Description

Beschrei bungDescription
Schaufelrad zum Auslegen von FalzproduktenPaddle wheel for laying folded products
Die Erfindung betrifft ein Schaufelrad zum Auslegen von Falzprodukten entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a paddle wheel for laying folded products according to the preamble of claim 1.
Durch die EP 01 64 440 B1 ist eine Vorrichtung zum Aufnehmen von Druckprodukten aus einem Falzapparat und zur Auslage auf einem Transportband bekanntgeworden, bei welcher die Druckprodukte jeweils zwischen zwei Schaufeln mehrerer in axialer Richtung beabstandeter Schaufelräder aufgenommen werden. In der Nähe des Grundes einer zwischen zwei Schaufeln befindlichen Schaufe l radtasche ist nabenfest jewei ls ein vorgespannter Hebelarm gelenkig angeordnet, um ein einlaufendes Druckprodukt abzubremsen.EP 01 64 440 B1 has disclosed a device for receiving printed products from a folder and for displaying them on a conveyor belt, in which the printed products are each taken up between two blades of a plurality of blade wheels spaced in the axial direction. A prestressed lever arm is arranged in an articulated manner in the vicinity of the base of a wheel bag located between two blades in order to brake an incoming printed product.
Nachtei lig bei dieser Vorrichtung ist jedoch, daß insbesondere dünne Druckprodukte infolge ihrer geringen Masse schwierig zwischen Hebelarm und Schaufel sowohl einbringbar als auch ausbringbar sind, was zu Unregelmäßigkeiten auf dem Auslegeband führt.Nachtei lig in this device is, however, that especially thin printed products are difficult to insert and remove between the lever arm and the shovel due to their small mass, which leads to irregularities on the delivery belt.
Durch die gattungsgemäße EP 01 04 383 B1 ist eine Vorrichtung zum Stapeln von blattförmigen Gegenständen bekannt, bei welcher zumindest eine der untereinander beabstandeten identischen Schaufe l radschei ben so zu den anderen Schaufe l radsche i ben verdreht ist, so daß die Räume zwischen den Schaufe l radtaschen der verschiedenen Schaufe l radschei ben nicht mehr miteinander fluchten und insbesondere die Vorderkante des blattförmigen Gegenstandes we l len l i ni enförmi g ausgebi ldet und somit festgeklemmt wird. Dies ist jedoch nur für dünne Produkte machbar, wobei diese dünnen Produkte an ihrer Vorderkante ggf. in unerwünschter Weise bleibend deformiert werden.The generic EP 01 04 383 B1 discloses a device for stacking sheet-like objects, in which at least one of the identical, spaced-apart shovels l wheel discs ben to the others Blade l wheel disc is twisted, so that the spaces between the blade wheel pockets of the various blade l wheel discs are no longer in alignment with one another and in particular the front edge of the sheet-like object is formed and thus clamped in place. However, this is only feasible for thin products, these thin products possibly being permanently deformed in an undesirable manner on their front edge.
Nach einer anderen Ausführungsvariante in o. g. EP 01 04 383 B1 weisen die Schaufe l radtaschen mindestens einer Schaufe l radschei be elastische Begrenzungswände, z. B. Blattfedern auf, um die Produkte an der Vorderseite festzuklemmen. Hierbei ist ebenso wie der EP 01 64 440 B1 nachtei lig, daß insbesondere dünne Produkte infolge ihrer geringen Masse schwierig in einem Spalt zwischen der vorgespannten Blattfeder und einer Schaufel zu führen bzw. lagerichtig abzugeben sind. Mit dieser Vorrichtung ist es nicht möglich, Produkte variabler Dicke lagerichtig auszulegen.According to another embodiment variant in the above. EP 01 04 383 B1 have the bucket l wheel pockets of at least one bucket l wheel disk be elastic boundary walls, z. B. leaf springs to clamp the products on the front. Here, like EP 01 64 440 B1, it is disadvantageous that, in particular, thin products are difficult to guide in a gap between the prestressed leaf spring and a blade or are to be dispensed in the correct position due to their low mass. With this device it is not possible to design products of variable thickness in the correct position.
Der Erfindung liegt die Aufgabe zugrunde, ein Schaufelrad zum Auslegen von Falzprodukten zu schaffen.The invention has for its object to provide a paddle wheel for laying folded products.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.
Die mit der Erfindung erzielbaren Vortei le bestehen insbesondere darin, daß die an die Dicke des auszulegenden Falzproduktes anpaßbare Weite der Öffnung der Schaufelradtaschen in der Nähe des Grundes der Schaufelradtaschen selbsttätig arretierbar ist. Dadurch wird eine stets dem Falzprodukt und der Maschinendrehzahl angepaßte Weite bzw. Breite des Taschengrundes eingestellt, so daß in jedem Falle eine lagerichtige übernähme bzw. Ausgabe von Falzprodukten erfolgen kann. Eine Verjüngung des Spaltes zwischen Schaufel und Leitstreifen verhindert ein Zurückprallen der Falzprodukte nach Erreichen des Schaufe lradgrundes . Insbesondere dünne Falzprodukte können nach dem Auftreffen ihrer Vorderkante auf dem Schaufelgrund ihre kinetische Energie gezieLt dadurch abbauen, daß sich die hintere Hälfte des Falzproduktes infolge des Anlegens in die sich in Richtung Schaufelspitze verbreitende Schaufe l radtasche zwischen Schaufel und Leitstreifen we l lenli ni enförmig verformt und nachfolgend wieder seine längsgestreckte Lage einnimmt. Die Schaufelradtaschen sind sowohl zur sicheren Aufnahme als auch zur lagerichtigen Abgabe von dicken oder dünnen Falzprodukten geeignet.The Vortei le achievable with the invention exist in particular in that the width of the opening of the paddle-wheel pockets, which can be adapted to the thickness of the folded product to be designed, can be locked automatically in the vicinity of the base of the paddle-wheel pockets. As a result, a width or width of the pocket base which is always adapted to the folded product and the machine speed is set, so that in any case a correct takeover or output of folded products can take place. A tapering of the gap between the blade and the guide strip prevents the folded products from rebounding after reaching the blade wheel base. In particular, thin folded products can reduce their kinetic energy after the impact of their front edge on the blade base by the fact that the rear half of the folded product deforms due to the application into the blade pocket, which spreads in the direction of the blade tip, between the blade and the guide strip subsequently resumes its elongated position. The paddlewheel bags are suitable both for secure pick-up and for the correct delivery of thick or thin folded products.

Ein Schaufelrad 1 ist mit seiner Nabe 2 drehfest auf einer sei tengeste l lfest gelagerten Antriebswelle 3 angeordnet. Die Nabe 2 weist radial nach außen gerichtete Speichen 5 auf, die an ihren Enden einen ringförmigen Schaufelhalter 10 tragen. Der Schaufelhalter 10 nimmt an seinem Umfang etwa in tangentialer Richtung verlaufende, gekrümmte Schaufeln 4 auf, die an ihrem Schaufelende 6 formschlüssig mit dem Schaufelhalter 10 verbunden sind. Für gleiche Teile werden jewei ls gleiche Tei lenummern verwendet. Die Schaufeln 4 überlappen einander, wobei in Uhrzeigerdrehrichtung A gesehen, zwischen der Außenseite 7, d. h. nabenfernen Seite einer Schaufel 4 und der Innenseite 8, d. h. nabennahen Seite einer vorangehenden Schaufel 4 jewei ls eine sich zum Taschengrund 9 hin verjüngende Schaufelradtasche 11 gebildet ist. Der Taschengrund 9 wird durch die Nabe 2 und einer Innenseite 8 einer Schaufel 4 gebi ldet. In Nähe der Schaufelspitze 12 jeder Schaufel 4 befindet sich ein Durchbruch 13, z. B. in rechteckiger Form, in welchem ein erstes Ende 14 eines Lei tst rei fens 16 schwenkbar befestigt, z. B. gelagert ist. Der Leitstreifen 16 erstreckt sich auf der Außenseite 7 d. h. der nabenfernen oder einer der Nabe 2 des Schaufelrades 1 abgewandten Seite einer jeden Schaufel 4 in Richtung Taschengrund 9 und endet vor dem Taschengrund 9, d. h. in der Nähe des Taschengrundes 9, ohne diesen mit seinem zweiten Ende 17 zu berühren. Der Leitstreifen 16 kann aus Federstahl bestehen, weist in etwa die Breite einer Schaufel 4 auf und liegt im Ruhezustand mit seinem zweiten Ende 17 an der nabennahen Innenseite 8 der benachbarten Schaufel 4 an, so daß die Breite b des Taschengrundes 9 gegen Null geht. An der nabennahen Innenseite 18 sowie in der Nähe des zweiten Endes 17 des blattfederartigen Leitstreifens 16 ist der Leitstreifen 16 gelenkig mit dem Betätigungsorgan eines Stellmittels, z. B. der Kolbenstange 19 eines pneumatischen Kurzhubzylinders 21, verbunden. Somit ist der Leitstreifen 16 an seinem zweiten Ende 17 in der Nähe des Taschengrundes 9 mittels eines Antriebes oder Stellmittels, z. B. der Kolbenstange 19, in radialer Richtung c des Schaufelrades 1 heb- und senkbar angeordnet. Jeder der jewei ls mit dem zweiten Ende 18 des Lei tst rei fens 16 verbundenen Kurzhubzylinder 21 befindet sich in einer in radialer Richtung zur Nabe 2 verlaufenden Bohrung 22, so daß die Hubrichtung C der Kolbenstange 19 des Kurzhubzylinders 21 ebenfalls in radialer Richtung der Nabe 2 bzw. des Schaufelrades 1 verläuft. Das Ende der Kolbenstange 19 ist mittels einer Gelenklasche 23, z. B. in Form eines Kettengliedes, mit dem Leitstreifen 16 verbunden. Das erste Ende 14 des Leitstreifens 16 ist abgewinkelt und halbkreisförmig ausgebi ldet, so daß das Ende 14 einen im Durchbruch 13 sich in achsparalleler Richtung zur Antriebswelle 3 erstreckenden Bolzen 24 hintergreift und somit ein Lager gebi ldet wird (Fig. 1 und 2).A paddle wheel 1 is arranged with its hub 2 in a rotationally fixed manner on a drive shaft 3 mounted on a fixed shaft. The hub 2 has radially outwardly directed spokes 5 which carry an annular blade holder 10 at their ends. The blade holder 10 accommodates curved blades 4 which run approximately in the tangential direction and which are connected to the blade holder 10 in a form-fitting manner at their blade end 6. The same part numbers are used for the same parts. The blades 4 overlap one another, as seen in the clockwise direction of rotation A, between the outside 7, ie the side of a blade 4 remote from the hub and the inside 8, ie the side of a preceding blade 4 near the hub, a blade wheel pocket 11 tapering toward the pocket base 9 is formed. The pocket base 9 is through the hub 2 and one Formed inside 8 of a blade 4. In the vicinity of the blade tip 12 of each blade 4 there is an opening 13, e.g. B. in a rectangular shape in which a first end 14 of a Lei tst rei fens 16 pivotally attached, for. B. is stored. The guide strip 16 extends on the outer side 7, ie the side of each blade 4 remote from the hub or one side facing away from the hub 2 of the impeller wheel 1, in the direction of the pocket base 9 and ends in front of the pocket base 9, ie in the vicinity of the pocket base 9, without the latter with its second Touch late 17. The guide strip 16 can be made of spring steel, has approximately the width of a blade 4 and, in the idle state, lies with its second end 17 on the inner side 8 of the adjacent blade 4 near the hub, so that the width b of the base 9 of the pocket approaches zero. On the inner side 18 near the hub and in the vicinity of the second end 17 of the leaf spring-like guide strip 16, the guide strip 16 is articulated with the actuating member of an adjusting means, eg. B. the piston rod 19 of a pneumatic short-stroke cylinder 21 connected. Thus, the guide strip 16 is at its second end 17 in the vicinity of the pocket base 9 by means of a drive or adjusting means, for. B. the piston rod 19, arranged in the radial direction c of the impeller 1 can be raised and lowered. Each of the short-stroke cylinders 21 connected to the second end 18 of the lead tire 16 is located in a bore 22 extending in the radial direction to the hub 2, so that the stroke direction C of the Piston rod 19 of the short-stroke cylinder 21 also extends in the radial direction of the hub 2 or the impeller 1. The end of the piston rod 19 is by means of a hinge plate 23, for. B. in the form of a chain link, connected to the guide strip 16. The first end 14 of the guide strip 16 is angled and semicircular, so that the end 14 engages behind a bolt 24 which extends in the opening 13 in the axis-parallel direction to the drive shaft 3 and thus forms a bearing (FIGS. 1 and 2).
Alle Kurzhubzylinder 21 weisen jewei ls einen Anschluß 26 für Druckluft auf, der mit einer Ringleitung 27 verbunden ist, die wiederum über eine Zuführ lei tung 28 mit einer Bohrung eines Achszapfens der Antriebswelle 3 in Verbindung steht. Dabei erfolgt die Druckluftzufuhr in den Kurzhubzylinder 21 vom Anschluß 26 zu einer Einströmöffnung 30, von welcher sie in den kolbenstangennahen Tei l des Kurzhubzylinders 21 einströmt. Auf dem Achszapfen befindet sich eine in Fig. 1 und 2 angedeutete bekannte Dreheinführung 29 für Druckluft. Die Dreheinführung 29 wird über ein bekanntes Druckregelventi l 31 mit Druckluft von einer zentralen Druckluftversorgung 32 versorgt, wobei das Druckregelventi l 31 mittels elektrischer Leitungen 33, 34 mit einem Vorei nste 11 rechne r 36, z. B. einem PC verbunden ist. Weiterhin ist der Vorei nste l l rechner 36 sowohl mit einem am Antrieb des Schaufelrades 1 befindlichen Drehzahlmesser 37, z. B. einem Tachogenerator als auch mit einer z. B. aus der DE 38 38 314 A1 bekanntenAll short-stroke cylinders 21 each have a connection 26 for compressed air, which is connected to a ring line 27, which in turn is connected via a feed line 28 to a bore of an axle of the drive shaft 3. The compressed air is supplied into the short-stroke cylinder 21 from the connection 26 to an inflow opening 30, from which it flows into the part of the short-stroke cylinder 21 near the piston rod. On the journal there is a known rotary introduction 29 for compressed air indicated in FIGS. 1 and 2. The rotary inlet 29 is supplied with compressed air from a central compressed air supply 32 via a known pressure regulating valve 31, the pressure regulating valve 31 using electrical lines 33, 34 with a preliminary 11 compute 36, e.g. B. is connected to a PC. Furthermore, the Vorei nste ll computer 36 with both on the drive of the impeller 1 tachometer 37, z. B. one Tachogenerator as well as with a z. B. from DE 38 38 314 A1 known

Auf der Antriebswelle 3 sind mehrere, voneinander beabstandete, jedoch ni chtdargeste l Ite Schaufelräder angeordnet. Die Schaufe l radtaschen 11 eines jeden Schaufelrades nehmen von einem nichtdargestellten Falzklappenzylinder oder einem Räderfalzwerk kommende Falzprodukte auf. Die zu transportierenden Falzprodukte variieren in ihrer Dicke zwischen vier und 160 Zeitungsseiten und bei Tabloi d-Produkten zwischen acht und 160 Seiten. Um eine störungsfreie Aufnahme in die Schaufe l radtaschen 11 und ein störungsfreie Abgabe aus den Schaufelradtaschen zu gewährleisten, ist die Breite b des Taschengrundes 9 der Schaufe l radtaschen 11 wie nachfolgend beschrieben einstellbar und arretierbar. In Abhängigkeit von der Dicke der durch die Schaufelräder 1 zu transportierenden Falzprodukte und in Abhängigkeit von der Drehzahl der Schaufelräder 1 wird der Luftdruck zur Betätigung der Kurzhubzylinder 21 festgelegt und z. B. eine Breite b des Taschengrundes 9 in radialer Richtung c des Schaufelrades 1 eingestellt (Fig. 2). Der drehzahlabhängige Wert wird zur Kompensation der Zentrifugalkraft der Leitstreifen 16 benötigt. Die Eingabe von Daten zum Falzprodukt kann über die Tastatur 39 erfolgen. Es ist jedoch auch möglich, bei NichtVorhandensein eines Vorei nste 11 rechners 36 sowie einer Falzprodukt-Dickenmeßeinrichtung 38 den Luftdruck mittels eines Fei nrege Iventi les von Hand an einer zentralen Bedieneinrichtung einzustellen, so daß dadurch die Breite b des Taschengrundes 9 ebenfalls einstellbar ist.A plurality of paddle wheels, which are spaced apart from one another but are not shown, are arranged on the drive shaft 3. The blade wheel pockets 11 of each blade wheel receive folding products coming from a folding jaw cylinder (not shown) or a wheel folding unit. The thickness of the folding products to be transported varies between four and 160 newspaper pages and between eight and 160 pages for tabloid products. In order to ensure trouble-free inclusion in the bucket l wheel bags 11 and trouble-free delivery from the bucket wheel bags, the width b of the pocket base 9 of the bucket l bike bags 11 can be adjusted and locked as described below. Depending on the thickness of the folded products to be transported by the paddle wheels 1 and depending on the speed of the paddle wheels 1, the air pressure for actuating the short-stroke cylinders 21 is determined and z. B. a width b of the pocket base 9 in the radial direction c of the impeller 1 is set (FIG. 2). The speed-dependent value is required to compensate for the centrifugal force of the guide strips 16. Data about the folded product can be entered via the keyboard 39. However, it is also possible, in the absence of a prior 11 computer 36 and a folded product thickness measuring device 38, to set the air pressure by means of a Fei nrege Iventi les by hand on a central control device, so that the width b of the pocket base 9 is also adjustable.
Weiterhin ist es möglich, als Stellmittel 21 statt eines Kurzhubzylinders zur Verstellung des zweiten Endes 17 des Leitstreifens 16 einen bekannten Stellspindelmotor einzusetzen. Der Stellspindelmotor besteht jewei ls aus einem nabenfesten Stator und einem ste l Ispi nde lfesten Rotor. Die Stellspindel wirkt in einer Führung dann jewei ls auf das zweite Ende 17 des Leitstreifens 16, wobei die Spindelstellung jeweils von einem Linearpotentiometer gemeldet wird. Stromleitungen können über den Achszapfen, z. B. über Schleifringe, hergestellt werden.Furthermore, it is possible to use a known adjusting spindle motor as the adjusting means 21 instead of a short stroke cylinder for adjusting the second end 17 of the guide strip 16. The adjusting spindle motor consists of a hub-fixed stator and a stationary isp-fixed rotor. The adjusting spindle then acts in a guide on the second end 17 of the guide strip 16, the spindle position being reported by a linear potentiometer. Power lines can over the journal, z. B. via slip rings.
Schließlich ist es auch noch möglich, das zweite Ende 17 des Leitstreifens 16 jewei ls mittels eines als Stellmittels wirkenden Nockens zu verstellen, welcher jewei ls fest mit einem Planetenrad verbunden ist. Ein nabengroßes, vom Schaufelrad getrennt antreibbares und am Schaufelrad 1 drehbar gelagertes Sonnenrad kämmt mit an seinem Umfang befindlichen Planetenrädern, wobei jedem Leitstreifen 16 ein Planetenrad mit Nocken zugeordnet ist Finally, it is also possible to adjust the second end 17 of the guide strip 16 by means of a cam which acts as an adjusting means and which is firmly connected to a planet gear. A hub-sized sun gear that can be driven separately from the impeller and rotatably mounted on the impeller 1 meshes with planet gears located on its circumference, each guide strip 16 having a planet gear with cams assigned
