Die auf der Zeichnung dargestellte Aufschnitt-Schneidemaschine für Nahrungsmittel, insbesondere Fleisch, Wurst, Käse und dgl. umfaßt in herkömmlicher Weise ein Maschinengestell 1, auf dem ein von einem Motor 2 drehend angetriebenes Kreismesser 3 gelagert ist. Statt des um eine gehäusefeste Achse rotierenden Kreismessers 3 können bei anderen Ausführungsformen der Erfindung auch oszillierende Schneidwerkzeuge, Bandmesser od. dgl. vorgesehen werden. Auf dem Maschinengestell 1 ist ferner ein Schlitten 4 gleitverschieblich, welcher der Aufnahme des Schneidgutes 5, beispielsweise einer Wurst (Fig. 2),sowie der Zuführung des Schneidgutes zum Messer 3 dient. Der Schlitten 4 ist auf Gleitführungen 6 in Richtung des Doppelpfeils S hin-und herverschieblich.The slicer for foodstuffs, in particular meat, sausage, cheese and the like shown in the drawing, comprises in a conventional manner a machine frame 1 on which a circular knife 3 driven by a motor 2 is mounted. Instead of the circular knife 3 rotating about an axis fixed to the housing, oscillating cutting tools, band knives or the like can also be provided in other embodiments of the invention. On the machine frame 1, a slide 4 can also be slid, which serves to receive the material to be cut 5, for example a sausage (FIG. 2), and to feed the material to be cut to the knife 3. The slide 4 can be pushed back and forth on slide guides 6 in the direction of the double arrow S.

Auf der dem Schlitten 4 gegenüberliegenden Seite des Messers 3 ist auf dem Maschinengestell 1 eine Fördervorrichtung 7 zur Abförderung der vom Messer abge schnittenen Schneidgutscheiben 8 zu einer Ablegefläche 9 angeordnet. Die Förderrichtung ist in Fig. 2 mit dem Pfeil T bezeichnet. Die Fördervorrichtung umfaßt in an sich bekannter Weise mehrere vertikal übereinander angeordnete Kettenbänder 11, von denen Spitzen 12 zur Aufnahme der Scheiben 8 abstehen. Die Kettenbänder 11 sind über eine Antriebswalze 13 und Spannräder 14 geführt. Die Antriebswalze 13 steht mit einem Antriebsmotor 15, z. B. über ein Schneckengetriebe 16, in Antriebsverbindung. Eine Zuführwalze 17 lenkt die durch das Messer 3 vom Schneidgut 5 abgeschnittenen Scheiben 8 auf die Spitzen 12 der Kettenbänder 11.On the side of the knife 3 opposite the carriage 4, a conveyor device 7 is arranged on the machine frame 1 for conveying the slices of cut material 8 cut from the knife to a depositing surface 9. The direction of conveyance is indicated by the arrow T in FIG. 2. The conveyor device comprises, in a manner known per se, a plurality of chain belts 11 arranged vertically one above the other, from which tips 12 protrude for receiving the disks 8. The chain belts 11 are guided over a drive roller 13 and tensioning wheels 14. The drive roller 13 is with a drive motor 15, for. B. via a worm gear 16, in drive connection. A feed roller 17 directs the disks 8 cut off from the material to be cut 5 by the knife 3 onto the tips 12 of the chain belts 11.

Auf dem Maschinengestell 1 ist ferner um eine Welle 18 schwenkbar ein Abschläger 20 gelagert, der in bekannter Weise eine um die Welle 18 verschwenkbare, normalerweise vertikal stehende Stütze 19 umfaßt, von welcher horizontale Stäbe 21 zwischen die einzelnen Kettenbänder 11 so abstehen, daß die Stäbe in Ruhelage des Abschlägers hinter den Spitzen 12 liegen. Dem Abschläger 20 ist schließlich ein Antrieb 40 in Gestalt eines handelsüblichen Hub- oder Drehmagneten zugeordnet, der die nach abwärts gerichtete Schwenkbewegung des Abschlägers 20 auslöst, um so die auf den Spitzen 12 von der Fördervorrichtung 7 mitgeführten Scheiben 8 abzuschlagen und auf die Ablegefläche 9 zu überführen.On the machine frame 1, a striker 20 is also pivotally mounted about a shaft 18 and, in a known manner, comprises a normally vertical support 19 which can be pivoted about the shaft 18 and from which horizontal bars 21 project between the individual chain belts 11 such that the bars in the rest position of the racket behind the tips 12. Finally, the striker 20 is assigned a drive 40 in the form of a commercially available lifting or rotating magnet, which triggers the downward swiveling movement of the striker 20, so as to knock off the disks 8 carried on the tips 12 by the conveying device 7 and towards the depositing surface 9 convict.

Die Ablegefläche ist bei der dargestellten Ausführungsform als Tisch ausgebildet, der in Richtung des Doppelpfeils U hin- und herverschieblich ist, so daß nacheinander abgelegte Scheiben 8, wie in Fig. 2 dargestellt, schuppenförmig übereinander angeordnet werden können.The storage surface is formed in the embodiment shown as a table which can be pushed back and forth in the direction of the double arrow U, so that successively deposited disks 8, as shown in FIG. 2, can be arranged in a scale-like manner one above the other.

Wesentlicher Bestandteil der Fördervorrichtung 7 ist deren Motor 15, welcher an die Stelle einer mechanischen Antriebsverbindung mit dem Schlitten 4 tritt. Um den Motor 15 der Fördervorrichtung 7 synchron mit dem Schlitten 4 anzutreiben, was für eine ordnungsgemäße Überleitung der abgeschnittenen Scheiben auf die Fördervorrichtung 7 vorteilhaft ist, ist folgende Anordnung getroffen:An essential component of the conveyor device 7 is its motor 15, which takes the place of a mechanical drive connection to the carriage 4. In order to drive the motor 15 of the conveying device 7 in synchronism with the carriage 4, which is advantageous for a proper transfer of the cut-off slices to the conveying device 7, the following arrangement is made:

Der Schlitten ist über einen Mitnehmer 24 an einen Antriebsriemen 25 angeschlossen, der über zwei Umlenkrollen 26,27 geführt ist. Somit werden die Umlenkrollen 26,27 bei hin- und hergehender Schlittenbewegung in Umlauf versetzt. Mit der Umlenkrolle 26 ist antriebsmäßig ein an sich bekannter Drehgeber 28 verbunden, beispielsweise dadurch, daß der Drehgeber 28 unmittelbar auf einer Welle 29 der Umlenkrolle 26 sitzt. Der Drehgeber 28 fühlt somit wegen seiner getriebemäßigen Verbindung mit dem Schlitten 4 dessen Position ab. Die vom Drehgeber 28 erzeugten Positionssignale werden über eine Steuerleitung 30 zu einer Nachführ-Steuereinrichtung 31 übertragen und dort ausgewertet. Die Steuereinrichtung 31 ist andererseits über eine weitere Steuerleitung 32 mit dem Motor 15 sowie dessen Geber verbunden, so daß aufgrund der aus dem Drehgeber 28 stammenden Positionssignale die Fördervorrichtung in Abhängigkeit von der Stellung des Schlittens 4 eingeschaltet, synchron nachgeführt und wieder abgeschaltet werden kann. Auf diese Weise können die abgeschnittenen Scheiben 8 ordnungsgemäß von der Fördervorrichtung 7 übernommen, abgefördert und über der Ablegefläche 9 abgelegt werden. Für die Ablage ist die Steuereinrichtung 31 über eine weitere Steuerleitung 33 mit dem Antrieb 40 des Abschlägers 20 verbunden. Über eine weitere, von der Steuereinrichtung 31 zum nicht gezeigten Antrieb der Ablegefläche 9 hinführende Steuerleitung 34 kann die Ablegefläche in Pfeilrichtung U entsprechend verstellt werden, wenn eine geschuppte Ablage der Scheiben 8 erwünscht ist.The carriage is connected via a driver 24 to a drive belt 25 which is guided over two deflection rollers 26, 27. Thus, the guide rollers 26, 27 are rotated during a reciprocating carriage movement. A known rotary encoder 28 is connected to the deflection roller 26 in terms of drive, for example in that the rotary encoder 28 is seated directly on a shaft 29 of the deflection roller 26. The encoder 28 thus senses the position of the carriage 4 because of its transmission connection. The position signals generated by the rotary encoder 28 become a tracking control device 31 via a control line 30 transferred and evaluated there. The control device 31, on the other hand, is connected via a further control line 32 to the motor 15 and its encoder, so that, based on the position signals coming from the rotary encoder 28, the conveying device can be switched on, synchronously adjusted and switched off again depending on the position of the carriage 4. In this way, the cut slices 8 can be properly taken over by the conveying device 7, conveyed away and placed over the depositing surface 9. For storage, the control device 31 is connected to the drive 40 of the striker 20 via a further control line 33. Via a further control line 34 leading from the control device 31 to the drive of the depositing surface 9, which is not shown, the depositing surface can be adjusted accordingly in the direction of the arrow U if a flaky depositing of the disks 8 is desired.

Die Anordnung arbeitet praktisch geräuschlos und ermöglicht eine präzise Scheibenablage. Wegen des einfachen Aufbaus können kaum Störungen auftreten. Die Wartung und Reinigung ist außerdem leicht und bequem ausführbar.The arrangement works practically noiselessly and enables precise disc placement. Due to the simple structure, hardly any faults can occur. Maintenance and cleaning can also be carried out easily and conveniently.

Bei der dargestellten Ausführungsform arbeitet die Nachführ-Steuereinrichtung 31 elektrisch. Bei anderen Ausführungsformen kann die beschriebene Nachführ-Steuerung auch auf pneumatischem oder hydraulischem Weg erfolgen.In the embodiment shown, the tracking control device 31 operates electrically. In other embodiments, the tracking control described can also be carried out pneumatically or hydraulically.

Der bei der dargestellten Ausführungsform vorgesehene, mit dem Schlitten 4 gekuppelte Drehgeber 28 kann auch durch ein anderes Abfühlmittel der Schlittenbewegung ersetzt werden, beispielsweise durch einen Winkelgeber oder einen Tachogenerator, die ebenfalls auf der Welle 29 der Umlenkrolle 26 angeordnet werden können. Ferner kann die Position des Schlittens 4 in ebenfalls bekannter Weise durch Ultraschallgeber, Magnetstreifen, Glasmaßstäbe, Widerstandsbahnen oder Lichtmeßstrecken entlang den Schlittenführungen 6 abgefühlt werden, wobei entsprechende Signale der Nachführ-Steuereinrichtung 31 zugeleitet werden.The rotary encoder 28 provided in the illustrated embodiment and coupled to the slide 4 can also be replaced by another sensing means of the slide movement, for example by an angle encoder or a tachometer generator, which can also be arranged on the shaft 29 of the deflection roller 26. Furthermore, the position of the carriage 4 can also be sensed in a known manner by means of ultrasound transmitters, magnetic strips, glass scales, resistance tracks or light measurement sections along the carriage guides 6, with corresponding signals being fed to the tracking control device 31.

Bei der dargestellten Ausführungsform treibt der Motor 15 die Fördervorrichtung 7 über ein Schneckengetriebe 16 an. Bei der erfindungsgemäßen Ausführungsform ist der Motor 15 direkt auf einer Antriebswelle der Fördervorrichtung 7, beispielsweise auf der Welle der Antriebswalze 13, angeordnet, wobei der Motor 15 auch innerhalb der Walze 16 liegen kann.In the embodiment shown, the motor 15 drives the conveyor device 7 via a worm gear 16. In the embodiment according to the invention, the motor 15 is arranged directly on a drive shaft of the conveying device 7, for example on the shaft of the drive roller 13, wherein the motor 15 can also lie within the roller 16.

Desweiteren ist bei der erfindungsgemäßen Ausführungsform vorgesehen, daß der Motor 15 der Fördervorrichtung 7 nach seiner Abschaltung als Bremse für die Fördervorrichtung wirkt, so daß diese augenblicklich abschaltet, sobald die abgeförderte Scheibe diejenige Position erreicht hat, in welcher sie von dem Abschläger 20 auf die Ablegefläche 9 überführt wird. Die Bremswirkung kann in an sich bekannter Weise durch Umpolen der Drehrichtung des Motors erreicht werden. Der Stillstand des Motors 15 kann in üblicher Weise an die Steuereinrichtung 31 zurückgemeldet werden, die dann den Abschläger 20 auslöst.Furthermore, it is provided in the embodiment according to the invention that the motor 15 of the conveying device 7 acts as a brake for the conveying device after it is switched off, so that this switches off immediately as soon as the disc which has been removed has reached the position in which it is transferred from the striker 20 to the depositing surface 9. The braking effect can be achieved in a manner known per se by reversing the polarity of the direction of rotation of the motor. The standstill of the motor 15 can be reported back to the control device 31 in a conventional manner, which then triggers the striker 20.

Ab einer voreinstellbaren Position des Schneidgutschlittens 4 kann die Fördervorrichtung 7 einen zusätzlichen Förderschnitt ausführen, d.h. eine zusätzliche Förderstrecke zurücklegen, so daß die abgeschnittene Scheibe unabhängig von der Schlittenbewegung aus dem Überleitbereich der Teile 3, 13 und 14 heraustransportiert und in Abschlagposition gebracht werden kann. Die Größe der im zusätzlichen Förderschritt zurückgelegten Förderstrecke kann durch übliche Zeitschaltglieder, Zählimpulsgeber, Wegmeßeinrichtungen oder ähnliches vorgegeben werden. Die voreinstellbare Position, ab welcher der zusätzliche Förderschritt eingeleitet wird, kann durch berührungslose oder kontaktbehaftete Schalter, die bestimmten Positionen des Schlittens 4 und/oder der Fördervorrichtung 7 zugeordnet sind, erkannt werden.From a pre-adjustable position of the product carriage 4, the conveying device 7 can carry out an additional conveying cut, ie cover an additional conveying path, so that the cut disc can be transported out of the transfer area of parts 3, 13 and 14 and brought into the knock-off position regardless of the carriage movement. The size of the conveying path covered in the additional conveying step can be specified by conventional timer elements, counting pulse generators, distance measuring devices or the like. The preset position from which the additional Conveying step is initiated, can be recognized by contactless or contact switches, which are assigned to certain positions of the carriage 4 and / or the conveyor device 7.

Aufgrund des erwähnten zusätzlichen Förderschritts ist es möglich, eine bestimmte Fördergeschwindigkeit der Fördervorrichtung 7 auch dann beizubehalten, wenn die Geschwindigkeit des Schlittens 4 nach Beendigung des Schneidhubes geändert wird. Hierdurch können die abgeschnittenen Scheiben besonders schonend in Ablegeposition überführt werden. Ein derartiger zusätzlicher Förderschritt kann, bequem von dem ohnehin vorhandenen Motor 15 der Fördervorrichtung abgeleitet werden.Due to the mentioned additional conveying step, it is possible to maintain a certain conveying speed of the conveying device 7 even if the speed of the carriage 4 is changed after the cutting stroke has ended. As a result, the cut-off slices can be transferred particularly gently into the storage position. Such an additional conveying step can be conveniently derived from the motor 15 of the conveying device which is present anyway.

Der zusätzliche Förderschritt kann auch so groß gewählt werden, daß die Gesamtförderstrecke der Fördervorrichtung 7 größer als die vom Schlitten 4 zurückgelegte Wegstrecke oder auch größer als die Breite der in Fig. 2 dargestellten Ablegefläche 9 ist. Hierdurch können bei entsprechender Länge der Fördervorrichtung 7 auch Ablegevorgänge in weiter entfernten Bereichen durchgeführt werden, beispielsweise können in größerem Abstand vorgesehene Förderbänder od. dgl. mit abgeschnittenen Scheiben beschickt werden. Insbesondere können die Scheiben während des zusätzlichen Förderschritts durch den Abschläger 20 auch von der umlaufenden Fördervorrichtung abgeschlagen werden.The additional conveying step can also be chosen so large that the total conveying distance of the conveying device 7 is greater than the distance traveled by the carriage 4 or also greater than the width of the placement surface 9 shown in FIG. 2. In this way, with the corresponding length of the conveying device 7, depositing operations can also be carried out in more distant areas, for example conveyor belts or the like provided at a greater distance can be loaded with cut-off slices. In particular, the discs can also be knocked off by the rotating conveying device during the additional conveying step by the striker 20.

Außerdem kann bei einer wiederum anderen Ausführungsform ebenso wie die Position des Schlittens 4 auch die Position der Fördervorrichtung 7 abgefühlt werden, um durch Vergleich eine synchrone Bewegung des Schlittens und der Fördervorrichtung festzustellen und nötigenfalls einzuregeln. Als Abfühlmittel eignen sich an der Fördervorrichtung 7 insbesondere Drehgeber od. dgl., die vorteilhafterweise auf der Achse des Motors 15 angeordnet werden können.In addition, in yet another embodiment, just like the position of the carriage 4, the position of the conveying device 7 can also be sensed in order to ascertain by comparison a synchronous movement of the carriage and the conveying device and, if necessary, to regulate them. Rotary encoders or the like, which can advantageously be arranged on the axis of the motor 15, are suitable as sensing means on the conveying device 7.

Ferner kann es vorteilhaft sein, die Fördergeschwindigkeit der Fördervorrichtung während des zusätzlichen Förderschritts in Abhängigkeit von der bei Einleitung des zusätzlichen Förderschrittes erreichten Schlittengeschwindigkeit einzusteuern.Furthermore, it can be advantageous to control the conveying speed of the conveying device during the additional conveying step as a function of the carriage speed reached when the additional conveying step is initiated.
