Description

Am rückwärtigen Ende greift in das Produkt eine sogenannte Kralle ein, die aus einem intermittierend angetriebenen Gehäuseblock besteht, an dessen vorderem Ende Greifer angeordnet sind, die mechanisch betätigbar in die rückwärtige Stirnseite des Produkts eingreifen und dieses halten. Der Greifer wird hierbei von einem Antrieb in Längsrichtung des Produktes gesehen intermittierend oder kontinuierlich angetrieben, so daß mit jedem Vorschub der Kralle das Produkt um einen bestimmten Weg auf der Rollenbahn gegen das Kreismesser verschoben wird und hierdurch dann eine Scheibe genau definierter Dicke vom Produkt abgeschnitten wird.At the rear end, a so-called claw engages in the product, which consists of an intermittently driven housing block the front end of which are arranged grippers that can be actuated mechanically reach into the rear end of the product and hold it. The gripper is driven by a drive in the longitudinal direction Seen product intermittently or continuously, so that with each advance of the claw the product moves a certain way on the roller conveyor against the circular knife and thereby then cut a slice of precisely defined thickness from the product becomes.

Mit derartigen Schneidemaschinen werden Produktgrößen bis zu einer Länge von 1,20 m verarbeitet. Bei der Verarbeitung derartig langer Produkte, insbesondere auch wenn diese Produkte eine relativ weiche Konsistenz haben, besteht der Nachteil, daß bei dem intermittierenden Antrieb des Produkts auf der Rollenbahn in Richtung auf das Kreismesser das Produkt zum Schwingen neigt, wobei dann die Scheibenstärken ungleichmässig werden. With such cutting machines, product sizes are up to a length of 1.20 m processed. When processing such long products, especially when these products have a relatively soft consistency have the disadvantage that the intermittent drive of the Product on the roller conveyor towards the circular knife the product tends to vibrate, the disc thickness then being uneven become.

Es kommt also zu unerwünschten Schwingungen im Produkt aufgrund des intermittierenden Vorschubantriebs dieses Produkts gegen das Kreismesser, wodurch es dann zu den erwähnten ungleichmässigen Scheiben kommt.So there are undesirable vibrations in the product due to the intermittent feed drive of this product against the Circular knife, which then leads to the aforementioned uneven slices is coming.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, den Vorschubantrieb einer Schneidemaschine der eingangs genannten Art so weiterzubilden, daß auch bei langen und relativ weichen Produkten Scheiben mit genau gleichbleibender Dicke geschnitten werden können.The present invention is therefore based on the object Feed drive of a cutting machine of the type mentioned above to train that even with long and relatively soft products Slices of exactly the same thickness can be cut.

Die Lösung der gestellten Aufgabe erfolgt durch die Merkmale des Patentanspruchs 1.The problem is solved by the features of claim 1.

Wesentliches Merkmal der vorliegenden Erfindung ist also, daß zwangsgekoppelt mit dem Antrieb der Kralle, die ja nur am hinteren Teil des Produkts ansetzt, nun auch am vorderen, nächst dem Kreismesser angeordneten Ende des Produkts ein weiterer Antrieb für das Produkt in Vorschubrichtung vorgesehen ist, wobei dieser Antrieb mit dem Antrieb der Kralle formschlüssig gekoppelt ist.An essential feature of the present invention is that positively coupled with the drive of the claw, which is only on the rear part of the product, now also on the front, next to the circular knife arranged end of the product another drive for the product in Feed direction is provided, this drive with the drive the claw is positively coupled.

Der kraft- und formschlüssige Antrieb in der Nähe des Kreismessers, der an der Unterseite des Produkts angreift, ist als Vorschubwalze ausgebildet, die an ihrem Außenumfang noch eine Zahnung aufweist, welche an der Unterseite in das Produkt eingreift.The non-positive and positive drive near the circular knife, the at the bottom of the product formed as a feed roller, which on her Outer circumference still has a toothing, which on the underside in the Product intervenes.

Die Zahnung ist vorzugsweise so gewählt, daß entsprechende Zahnmarken mit den später abgeschnittenen Scheiben korrespondieren, so daß man derartige Zahnmarken dann später beim abgeschnittenen Produkt nicht mehr sieht.The toothing is preferably chosen so that corresponding tooth marks with the later cut slices correspond, so that one such Then tooth marks will no longer be seen when the product is cut off.

Eine Kopplung des Antriebs der Vorschubwalze mit dem Antrieb für die Kralle ist in einer bevorzugten Ausbildung der Erfindung dadurch verwirklicht, daß die Vorschubwalze drehfest mit einem Antriebsrad verbunden ist, über welches Antriebsrad ein Zahnriemen läuft, der als geschlossenes Trum über eine Umlenkrolle geführt ist. Dieser Zahnriemen ist nun mit der Kralle unmittelbar über eine Klemmung gekoppelt, so daß bei einem entsprechenden Antrieb der Kralle der Zahnriemen mitgenommen wird und über das Antriebsrad die Vorschubwalze drehend in Vorschubrichtung antreibt.A coupling of the drive of the feed roller with the drive for the Claw is thereby in a preferred embodiment of the invention realizes that the feed roller rotatably with a drive wheel is connected via which drive wheel runs a toothed belt, which as closed run is guided over a pulley. This timing belt is now coupled to the claw directly via a clamp, so that if the claw is driven appropriately, the toothed belt is carried along and the feed roller turns in via the drive wheel Feed direction drives.

Vorteil dieser Ausführung ist, daß man auf einen eigenen Antriebsmotor für die Vorschubwalze verzichten kann und einen absolut synchronen Antrieb zwischen der Kralle und der Vorschubwalze erhält.The advantage of this version is that you have your own drive motor can dispense with the feed roller and an absolutely synchronous Drive between the claw and the feed roller receives.

In einer Weiterbildung der vorliegenden Erfindung ist es jedoch auch vorgesehen, daß der Vorschubwalze ein eigener Antrieb zugeordnet ist, der mit dem Antrieb der Kralle entsprechend synchronisiert ist.In a further development of the present invention, however, it is also provided that the feed roller is assigned its own drive, which is synchronized with the drive of the claw accordingly.

Mit der gegebenen technischen Lehre wird der wesentliche Vorteil erzielt, daß das Produkt nun praktisch an zwei Enden angetrieben wird, nämlich an seinem rückwärtigen Ende und an seinem nächst dem Kreismesser liegenden Ende. Das Produkt wird somit zwischen diesen beiden Antrieben, die absolut synchron laufen, stabilisiert und neigt deshalb nicht mehr zum Schwingen, auch wenn Produkte relativ weicher Konsistenz verwendet werden. Damit ist es nun erstmals möglich, auch bei sehr großen Produktlängen und sehr weichen Produkten einen absolut gleichmässigen Schnitt zu erreichen, so daß auch bei derartigen schwierig zu bearbeitenden Produkten eine gleichmässige Scheibenstärke beim Abschneiden mit dem Kreismesser erreicht wird.With the given technical teaching, the main advantage achieved that the product is now practically driven at two ends, namely at its rear end and at its closest to the circular knife lying end. The product is thus between these two drives, which run absolutely in sync, stabilize and therefore no longer incline for swinging, even when using products with a relatively soft consistency become. It is now possible for the first time, even with very large ones Product lengths and very soft products are absolutely uniform To achieve cut, so that even with such difficult processing products a uniform slice thickness Cutting with the circular knife is achieved.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere Merkmale und Vorteile der Erfindung hervor.

Hinsichtlich der Funktion des Vorschubantriebs, des Aussehens der Kralle und weiterer Einzelheiten wird auf das ältere Patent DE 32 49 925 C2 des gleichen Anmelders verwiesen.Regarding the function of the feed drive, the appearance of the claw and further details are based on the older patent DE 32 49 925 C2 referenced by the same applicant.

Das zu schneidende Produkt 1 liegt auf einer Rollenbahn 2 auf, die beispielsweise im Winkel von 45° nach unten zur Horizontalen geneigt ist, wobei die Rollenbahn aus einzelnen Rollen 18 bestehen, die parallel zueinander in gegenseitigem Abstand drehbar angeordnet sind. Das Produkt 1 wird mit seinem vorderen Stirnende gegen ein Kreismesser 4 geführt, welches über eine Antriebswelle 8 mit einem Exzenter 7 verbunden ist, der dem Kreismesser 4 eine exzentrische Schnittbewegung zuordnet.The product 1 to be cut rests on a roller conveyor 2 which for example inclined at an angle of 45 ° down to the horizontal is, the roller conveyor consist of individual rollers 18, which are parallel are rotatably spaced from each other. The product 1 is guided with its front end against a circular knife 4, which is connected to an eccentric 7 via a drive shaft 8, which assigns an eccentric cutting movement to the circular knife 4.

Gehäusefest ist dem Kreismesser 4 ein Gegenmesser 5 zugeordnet, welches auf einem ebenfalls gehäusefesten Messerbalken 6 gelagert ist.Fixed to the housing, the circular knife 4 is assigned a counter knife 5, which is mounted on a knife bar 6 which is also fixed to the housing.

Das Produkt kann ggf. an seiner Oberseite durch einen Niederhalter 10 gegen das Gegenmesser 5 gepresst werden, wobei die hierzu erforderliche Preßkraft durch einen Pneumatikzylinder 9 aufgebracht wird.The product can optionally be held at the top by a hold-down device 10 are pressed against the counter knife 5, the required for this Pressing force is applied by a pneumatic cylinder 9.

Der Vorschubantrieb des Produkts 1 wird durch eine sogenannte "Kralle 11" bewerkstelligt, welche Kralle im wesentlichen als Antriebsgehäuse ausgebildet ist, in dessen Innenraum auf jeweils parallel zueinander und übereinanderliegenden Wellen 13 Greifer 12 angeordnet sind. Jede Welle 13 trägt entsprechend der Figur 1 eine Reihe von einen gegenseitigen Abstand zueinander einnehmenden und parallel zueinander angeordneten Greifern 12, wobei die beiden Wellen über entsprechende Zahnräder miteinander in Eingriff sind und ihrerseits von einem Zahnrad 17 in den Pfeilrichtungen 14 drehangetrieben sind.The feed drive of the product 1 is by a so-called "claw 11 "accomplished, which claw essentially as a drive housing is formed, in the interior of each parallel to each other and superimposed shafts 13 grippers 12 are arranged. Every wave 13 carries a series of one another according to FIG Spacing and parallel to each other Grippers 12, the two shafts via corresponding gears are in engagement with each other and in turn from a gear 17 in the Arrow directions 14 are driven in rotation.

Der Antrieb des Zahnrades 17 erfolgt hierbei über eine Schubstange 16, die von einem Pneumatikzylinder 15 beaufschlagt wird.The gear 17 is driven via a push rod 16, which is acted upon by a pneumatic cylinder 15.

Mit der Betätigung des Pneumatikzylinders 15 wird somit die Schubstange 16 verschoben; damit wird das Zahnrad 17 verdreht, und nachdem das Zahnrad 17 mit mindestens einem Zahnrad einer Welle 13 kämmt, werden die Wellen 14 in einer der eingezeichneten Pfeilrichtungen 14 verdreht, wodurch die Greifer 12 in die rückwärtige Stirnseite des Produkts 1 eingreifen und das Produkt derart festhalten. With the actuation of the pneumatic cylinder 15, the push rod 16 postponed; so that the gear 17 is rotated, and after that Gear 17 meshes with at least one gear of a shaft 13, the Shafts 14 rotated in one of the indicated arrow directions 14, whereby the grippers 12 into the rear end face of the product 1 intervene and hold the product in this way.

Der Vorschubantrieb der Kralle 11 erfolgt dadurch, daß die gesamte Kralle 11 auf einer Krallenschiene 21 gelagert ist, die ihrerseits in einem Lagergehäuse 22 befestigt ist. Im Lagergehäuse 22 sind Linearlager 23 angeordnet, so daß das Lagergehäuse 22 über diese Linearlager 23 auf einer Prismenschiene 24 in Vorschubrichtung (Pfeilrichtung 3) und ggf. in Gegenrichtung hierzu bewegbar ist.The feed drive of the claw 11 takes place in that the entire Claw 11 is mounted on a claw rail 21, which in turn in a bearing housing 22 is attached. Linear bearings are in the bearing housing 22 23 arranged so that the bearing housing 22 on this linear bearing 23 a prism rail 24 in the feed direction (arrow direction 3) and possibly is movable in the opposite direction.

Zur leichten Auswechselbarkeit der Kralle 11 auf der Krallenschiene 21 ist es vorgesehen, daß gemäss Figur 1 an der Unterseite der Kralle 11 eine Ausnehmung 37 angeordnet ist, in welche die Krallenschiene 21 eingeschoben und in nicht näher dargestellter Weise festgeklemmt ist. Auf diese Weise kann die Kralle 11 leicht von der Krallenschiene 21 abgezogen werden.For easy interchangeability of the claw 11 on the claw rail 21 it is provided that according to FIG. 1 on the underside of the claw 11 a recess 37 is arranged, into which the claw rail 21 inserted and clamped in a manner not shown. In this way, the claw 11 can be easily removed from the claw rail 21 subtracted from.

Damit besteht der Vorteil, daß die Kralle 11 leicht ausgewechselt und gereinigt werden kann.This has the advantage that the claw 11 easily replaced and can be cleaned.

In Figur 1 ist lediglich angedeutet, während in Figur 2 die entsprechende zeichnerische Darstellung fehlt, daß der Vorschub des Lagergehäuses 22, an dem die Krallenschiene 21 befestigt ist, über eine Kugelspindel 19 erfolgt, wobei die Kugelspindel eine nicht näher dargestellte Spindelmutter im Lagergehäuse 22 durchgreift und von einem Drehantrieb intermittierend in Pfeilrichtung 20 angetrieben ist.In Figure 1 is only indicated, while in Figure 2 the Corresponding graphic representation is missing that the feed of the Bearing housing 22, on which the claw rail 21 is attached, via a Ball spindle 19 takes place, the ball spindle not one closer shown spindle nut engages in the bearing housing 22 and by one Rotary drive is driven intermittently in the direction of arrow 20.

Mit Hilfe dieses Antriebs wird also die Kralle 11 in Vorschubrichtung 3 intermittierend derart angetrieben, daß ein genau definierter Vorschub in Richtung auf das Kreismesser 4 stattfindet und das Kreismesser eine genau definierte Scheibe von dem Produkt 1 abschneidet.With the help of this drive, the claw 11 is thus in the feed direction 3 intermittently driven in such a way that a precisely defined feed takes place in the direction of the circular knife 4 and the circular knife one cuts precisely defined slice from product 1.

Erfindungsgemäss ist nun vorgesehen, daß auch am vorderen Ende in der Nähe des Kreismessers 4 das Produkt 1 von einer zusätzlichen Vorschubeinrichtung angetrieben wird. Die Vorschubeinrichtung besteht aus einer Vorschubwalze 33, die an ihrem Außenumfang eine Zahnung 35 aufweist. Diese Zahnung 35 gräbt sich mindestens teilweise in die Unterseite des Produkts 1 ein.According to the invention it is now provided that at the front end in the Near the circular knife 4 the product 1 of an additional one Feed device is driven. The feed device consists of a Feed roller 33, which has a toothing 35 on its outer circumference. This toothing 35 digs at least partially in the bottom of the Product 1 a.

Die Vorschubwalze 33 ist drehbar auf einer Achse 32 gelagert, wobei das Antriebsrad 29 mit der Vorschubwalze 33 gekuppelt ist. Das Antriebsrad 29 wird von einem endlosen Zahnriemen 25 umschlungen, welcher an seiner anderen Seite über eine hintere Umlenkrolle 27 läuft. Die Umlenkrolle ist hierbei in einem gehäusefesten Halter 28 drehbar gelagert.The feed roller 33 is rotatably mounted on an axis 32, which Drive wheel 29 is coupled to the feed roller 33. The drive wheel 29 is wrapped by an endless toothed belt 25, which on its other side runs over a rear pulley 27. The pulley is rotatably mounted in a housing-fixed holder 28.

Erfindungsgemäss ist nun die Krallenschiene 21 über eine Klemmung 26 mit dem oberen oder unteren Trum des Zahnriemens 25 verklemmt und damit kraftschlüssig gekoppelt. Somit wird bei einem entsprechenden Antrieb des Lagergehäuses 22 in Vorschubrichtung 3 über die Kopplung der Krallenschiene 21 mit dem Zahnriemen 25 auch das Antriebszahnrad 29 angetrieben, welches seinerseits drehfest mit der Vorschubwalze 33 gekoppelt ist.According to the invention, the claw rail 21 is now connected via a clamp 26 the upper or lower run of the toothed belt 25 and thus jammed non-positively coupled. Thus, with a corresponding drive of the bearing housing 22 in the feed direction 3 via the coupling of the Claw rail 21 with the toothed belt 25 and the drive gear 29 driven, which in turn rotatably with the feed roller 33rd is coupled.

Es wird noch erwähnt, daß die Lagerung der Achse 32 auf jeweils seitlichen Lagerplatten 30 erfolgt, wobei die Lagerplatten ggf. unter Zwischenschaltung eines Distanzblocks 31 am Gehäuse befestigt sind.It is also mentioned that the bearing of the axis 32 on each lateral bearing plates 30 takes place, the bearing plates possibly under Interposition of a spacer block 31 are attached to the housing.

Es kann zusätzlich vorgesehen sein, das Produkt noch über seitlich am Produkt 1 ansetzende Seitenführungen 38 noch zusätzlich zu führen.It can also be provided that the product is still on the side To add product 1 side guides 38 additionally.

Aufgrund der kraftschlüssigen Kopplung zwischen dem Vorschub der Kralle 11 und der Drehung der Vorschubwalze 33 können keine Schwingungen mehr im Produkt im Zwischenraum zwischen der Vorschubwalze 33 und der Kralle 11 auftreten, weil dieser Bereich exakt in Vorschubrichtung synchron angetrieben ist. Die Scheibestärke des geschnittenen Produkts ist damit absolut gleichmässig. Damit wird im übrigen gewährleistet, daß die Zustellbewegung (Vorschubbewegung) der Kralle nicht nur am hinteren Teil des Produkts eingeleitet wird, sondern zusätzlich noch am vorderen Teil des Produkts wirkt. Due to the non-positive coupling between the feed of the claw 11 and the rotation of the feed roller 33 can no longer vibrate in the product in the space between the feed roller 33 and the claw 11 occur because this area is synchronous exactly in the feed direction is driven. The slice thickness of the cut product is now absolutely even. This also ensures that the Infeed movement (feed movement) of the claw not only on the rear part of the product is introduced, but also on the front part of the product works.
