Abstract

A supporting device for a product (13) for splicing on a carriage (1) of a slicing machine includes, near the cutting plane, a slide (12) on a slideway (sleeve 11), which is mounted on a rail (10) so as to be displaceable by means of an electrical drive (15). The electrical drive (15), especially with a belt drive (16), engages with the slideway (sleeve 10), which tilts when subjected to a load and counteracts a push backwards in a self-locking manner. The point of application (17) of the drive on the slideway introduces restoring forces to the latter, which counterbalance the self-locking and align the slideway so that it is parallel on the rail (10). The rail (10) can be folded upwards and can be arranged horizontally or vertically. A position indicator, for example a pulse generator which counts the revolutions of the motor (15), is connected to a control system for a distributing device for determination of the diameter. …<IMAGE>…

Description

Die Erfindung betrifft eine Abstützeinrichtung für Schnittgut auf einem Schnittgutwagen einer Aufschnittschneidemaschine mit einem Schieber, der auf einer Schiene nahe der Schnittebene den Abmessungen zur Lagefixierung des Schnittgutes im Schnittbereich einstellbar angeordnet ist.The invention relates to a support device for clippings on a clippings wagon of a slicing machine with a slide which is arranged on a rail near the cutting plane, the dimensions for fixing the clippings in the cutting area are adjustable.

Bei händisch betätigten Schnittgutwagen sind Schnittguthalter bekannt, die einen Schwenkarm mit einer Halteplatte und einein Restehalter umfassen. Der Schwenkarm wird hochgeschwenkt, ein Schnittgut wird auf dem Schnittgutwagen aufgelegt und bei Zurückschwenken des Schwenkarmes durch die Halteplatte lagefixiert. Das Schnittgut wir sodann gegen eine verstellbare Anschlagplatte geschoben, an die das Kreismesser anschließt. Es sind ferner automatische Aufschnittschneidemaschinen bekannt, bei welchem der Schnittgutwagen durch einen elektromechanischen Reversierantrieb längs der Anschlagplatte hin- und hergeführt wird. Ein Schnittgut, z.B. eine Wurststange, wird durch die oben beschriebene Einspannung mittels Schwenkarm und Halteplatte festgehalten, allerdings bewegt sich der unmittelbar im Schnittbereich befindliche Teil des Schnittgutes, der die Reaktionskräfte des Kreismessers und allenfalls die Reibungskräfte der Schnittfläche des Schnittgutes auf der Anschlagplatte aufnimmt. Je weicher das Schnittgut und je länger der die Einspannung überragende Teil desselben, ist, umso drastischer wirkt sich die Eigenbewegung des Schnittgutes trotz der beschriebenen Einspannung aus. Eine Abhilfe kann eine bekannte Abstützeinrichtung schaffen, die eine auf dem Schnittgutwagen nahe dem Schnitt-bereich angeordnete Schiene oberhalb der Auflagefläche des Schnittgutwagens umfaßt, die einen seitlich gegen das Schnittgut preßbaren Schieber trägt. Mit Hilfe dieses Schiebers, kann das Schnittgut im Schnittbereich so festgehalten werden, daß es den Schnittkräften nicht ausweichen kann und sich dadurch auch bei relativ weichem Schnittgut geometrisch exakte geschnittene Scheiben ergeben. Als nachteilig hat sich allerdings erwiesen, daß diese Abstützeinrichtung händisch eingestellt und dem jeweiligen Schnittgut angepaßt werden muß und daß sich Verzerrungen des Schnittgutes infolge des gleichzeitig erforderlichen Vorschubes des Schnittgutes ergeben.In the case of manually operated clippings wagons, clippings holders are known which comprise a swivel arm with a holding plate and a rest holder. The swivel arm is swiveled up, a clippings are placed on the clippings wagon and fixed in position when the swivel arm is swiveled back by the holding plate. The clippings are then pushed against an adjustable stop plate to which the circular knife connects. Automatic slicers are also known, in which the cut wagon is moved back and forth along the stop plate by an electromechanical reversing drive. A clippings, e.g. a sausage stick, is held in place by the above-described clamping using a swivel arm and holding plate, but the part of the clippings located directly in the cutting area moves, which absorbs the reaction forces of the circular knife and, if necessary, the frictional forces of the cut surface of the clippings on the stop plate. The softer the clippings and the longer the part of the clipping projecting above them, the more drastic is the movement of the clippings despite the described clamping. This can be remedied by a known support device, which comprises a rail arranged on the clippings wagon near the cutting area above the support surface of the clippings wagon, which carries a slide that can be pressed laterally against the clippings. With the help of this slider, the clippings can be held in the cutting area in such a way that they cannot avoid the cutting forces and this results in geometrically exact cut slices even with relatively soft clippings. It has proven disadvantageous, however, that this support device must be adjusted manually and adapted to the respective clippings and that the clippings are distorted as a result of the simultaneously required advancement of the clippings.

Die Erfindung zielt darauf ab, eine automatische Abstützeinrichtung für Schnittgut im Schnittbereich zu schaffen, deren Schieber sich selbsttätig an die jeweiligen Schnittgutgrößen anpaßt und der das Schnittgut beim Schnitt klemmend festhält, jedoch beim Vorschub des Schnittgutes öffnet. Dies wird dadurch erreicht, daß der Schieber als ein von einer Gleitführung, insbesondere Hülse, auskragender Ausleger ausgebildet und die Gleitführung unter Last selbsthemmend auf der Schiene gelagert ist und daß die Gleitführung mit einem elektrischen Antrieb, insbesondere mit einem Riementrieb, über einen die Selbsthemmung aufhebenden Angriffspunkt auf der Gleitführung verbunden ist. Durch Verkanten der Gleitführung, bedingt durch die Reaktionskraft des festzuhaltenden Schnittgutes, ist die Abstützeinrichtung unter Last selbstklemmend. Dieses Verkanten wird durch eine Einleitung der Antriebskräfte, die den Reaktionskräften der Last entgegenwirken, aufgehoben. Wenn die Schiene horizontal oberhalb der Auflagefläche des Schnittgutwagens und der Schieber in Richtung auf die Auflagefläche des Schnittgutwagens auskragend angeordnet sind, dann wird das Schnittgut gegen die Schulter des Schnittgutwagens gedrückt und ist somit von zwei starren Flächen sowie von zwei einstellbaren Halte- bzw. Klemmeinrichtungen innerhalb eines Rechteckes eingeschlossen. Eine andere Ausführung sieht vor, daß die Schiene in vertikaler Richtung und rechtwinkelig zur Auflagefläche des Schnittgutwagens und der Schieber in paralleler Richtung zur Auflagefläche auskragend angeordnet sind. Auf diese Weise werden Lageabweichungen des Schnittgutes in vertikaler Richtung unterbunden. Es können auch Schieber in beiden vorgenannten Richtungen und bzw. oder auch in einer 45° Lage zur Auflagefläche des Schnittgutes vorgesehen sein. Schließlich ist es zweckmäßig, wenn die Schiene hochklappbar oder seitlich wegklappbar ausgebildet ist. Diese Position dient dem Beladen des Schnittgutwagens mit Schnittgut. Eine konkrete Ausführungsform der Erfindung ist dadurch gekennzeichet, daß ein Elektromotor für den Riementrieb vorgesehen ist, der strombegrenzt beim Auflaufen des Schiebers auf ein Schnittgut abschaltbar und bzw. oder auf eine reduzierte Haltespannung umschaltbar ist. Wenn der Schieber auf dem Schnittgut aufläuft, erhöht sich der Motorstrom des Antriebs, der überwacht wird und der bei Erreichen eines einstellbaren Schwellenwertes zum Abschalten bzw. Umschalten des Motors auf eine schonende Haltespannung umgeschaltet wird. Ferner ist es zweckmäßig, wenn eine Steuerung für den Antrieb des Schiebers vorgesehen ist, die beim Einschalten eines Vorschubantriebs des Schnittguts den Schieberantrieb reversiert und beim Abschalten des Vorschubantriebes den Schieberantrieb in die Abstützposition führt. Damit arbeiten Vorschubantrieb und Antrieb der Klemmeinrichtung abwechselnd. Ein Vorschub gegen die Klemmkräfte kann so vermieden werden. Bei einer Aufschnittschneidemaschine mit Ablegesystem ist es zweckmäßig, wenn der Schieber, bzw. die Schieber, mit einem Stellungsmelder in Verbindung stehen, wobei insbesondere der Antrieb an einen Impulszähler zur Zählung von Impulsen proportional dem Vorschub angeschlossen ist, und wenn das Signal des Stellungsmelders zur Größenermittlung, insbesondere Durchmesserermittlung des Schnittgutes einer Steuerung für ein Ablegesystem von geschnittenen Scheiben des Schnittgutes zuführbar ist. Ablegesysteme arbeiten vielfach unter Berücksichtigung der Schnittgutabmessungen, damit gegenseitige Abstände von Schnittgutscheiben und randseitige Überstände auf einem Tablett, beispielsweise einem Schnittgutdurchmesser, angepaßt werden können. Dazu sind Meßeinrichtungen meist auf optischer Basis vorgesehen. Wenn eine erfindungsgemäße Abstützeinrichtung verwendet wird, dann kann diese die Aufgabe der Durchmesser- bzw. Schnittgutgrößenerfassung mitübernehmen.The invention aims to provide an automatic support device for clippings in the clipping area, the slider of which automatically adapts to the respective clippings sizes and which holds the clippings in place during the clipping, but opens when the clippings are fed. This is achieved in that the slide is designed as a cantilever projecting from a slide guide, in particular a sleeve, and the slide guide is mounted on the rail in a self-locking manner under load, and in that the slide guide with an electric drive, in particular with a belt drive, via a self-locking device which cancels the self-locking Attack point is connected to the sliding guide. By tilting the sliding guide, due to the reaction force of the clippings to be held, the support device is self-locking under load. This tilting is eliminated by the introduction of the driving forces, which counteract the reaction forces of the load. If the rail is arranged cantilevered horizontally above the contact surface of the clippings wagon and the slide in the direction of the contact surface of the clippings wagon, then the clippings are pressed against the shoulder of the clippings wagon and are thus within two rigid surfaces and two adjustable holding or clamping devices enclosed in a rectangle. Another embodiment provides that the rail in the vertical direction and at right angles to the support surface of the clippings wagon and the slide in the parallel direction to the support surface are arranged cantilever. In this way, deviations in position of the material to be cut in the vertical direction are prevented. Sliders can also be provided in both of the aforementioned directions and / or also in a 45 ° position to the contact surface of the material to be cut. Finally, it is expedient if the rail is designed to be folded up or folded away to the side. This position is used to load the clippings wagon with clippings. A specific embodiment of the invention is characterized in that an electric motor is provided for the belt drive, which can be switched off in a current-limited manner when the slider runs onto a clippings and / or can be switched over to a reduced holding voltage. If the slider hits the clippings, it increases Motor current of the drive, which is monitored and which is switched to a gentle holding voltage when an adjustable threshold value for switching off or switching over the motor is reached. Furthermore, it is expedient if a control is provided for driving the slide, which reverses the slide drive when a feed drive of the clippings is switched on and leads the slide drive into the supporting position when the feed drive is switched off. The feed drive and the drive of the clamping device work alternately. A feed against the clamping forces can be avoided in this way. In a slicer with a filing system, it is expedient if the slide or the slides are connected to a position indicator, the drive in particular being connected to a pulse counter for counting pulses proportional to the feed, and if the signal from the position indicator is used to determine the size , in particular determining the diameter of the clippings a controller for a depositing system of cut slices of the clippings can be fed. Laying systems often work taking into account the clippings dimensions so that mutual distances between clippings slices and overhangs on the edge can be adapted on a tray, for example a clippings diameter. For this purpose, measuring devices are usually provided on an optical basis. If a support device according to the invention is used, then it can also take on the task of detecting the diameter or material size.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Zeichnungen dargestellt. Fig. 1 zeigt schematisch einen Schnitt durch einen Schnittgutwagen nach der Linie I-I in Fig.2, und Fig. 2 eine Stirnansicht des Schnittgutwagens.An embodiment of the subject of the invention is shown in the drawings. 1 schematically shows a section through a clippings wagon along the line I-I in FIG.

Ein Schnittgutwagen 1 ist in Pfeilrichtung (Pfeil 2) auf einer Aufschnittschneidemaschine gegenüber einer Anschlagplatte 3 und einer Messerscheibe 4 hin- und her beweglich. Bei automatischen Maschinen besorgt diesen Hub des Schneidevorganges ein elektrischer Reversierantrieb. Auf dem Schnittgutwagen 1 sind Führungsstangen 5, 6 vorgesehen, auf welchen ein Führungsschlitten 7 für einen schwenkbaren Schnittguthalter 8 gelagert ist. Wie Fig. 2 zeigt, sitzt auf der Führungsstange 5 (mit dieser drehfest verbunden) ein Träger 9 mit einer Schiene 10, auf der eine Hülse 11 verschiebbar gelagert ist. Die Hülse 11 trägt einen weit ausladenden Schieber 12, welcher gemäß Fig. 1 ein Schnittgut 13 gegen die Schulter 14 des Schnittgutwagens 1 drückt und dieses auf diese Weise im Schnittbereich nahe der unmittelbaren Schnittebene festhält.A clippings wagon 1 can be moved back and forth in the direction of the arrow (arrow 2) on a slicing machine relative to a stop plate 3 and a knife disk 4. In automatic machines, this stroke of the cutting process is provided by an electric reversing drive. Guide rods 5, 6 are provided on the clippings wagon 1, on which a guide carriage 7 for a pivotable clippings holder 8 is mounted. 2 shows, sits on the guide rod 5 (with this rotatably connected) a carrier 9 with a rail 10 on which a sleeve 11 is slidably mounted. The sleeve 11 carries a widely protruding slide 12 which, according to FIG. 1, presses a clippings 13 against the shoulder 14 of the clippings wagon 1 and in this way holds it in the cutting region near the immediate cutting plane.

Ein Elektromotor 15 ist auf der Schiene 10 vorgesehen, der über einen Zahnriementrieb 16 mit der Hülse 11 in Verbindung steht. Der Angriffspunkt 17 auf der Hülse 11 ist so gewählt, daß einer Schrägstellung der Hülse 11, bedingt durch das Schnittgut 13 nach Auflaufen des Schiebers 12 auf derselben, beim Zurückziehen der Hülse 11 entgegengewirkt wird. Durch die Schrägstellung der Hülse 11 auf der Schiene 10 ergibt sich eine Selbsthemmung die ein Zurückweichen des Schiebers 12 verhindert. Erst wenn der Zahnriementrieb 16 an dem Angriffspunkt in Freigaberichtung anzieht, dann löst sich die Selbsthemmung und das Schnittgut 13 ist im Schnittbereich, z.B. für den Vorschub, freigegeben. Der Schieber 12 kann in die Position 12′ zurückgefahren werden.An electric motor 15 is provided on the rail 10, which is connected to the sleeve 11 via a toothed belt drive 16. The point of attack 17 on the sleeve 11 is chosen so that an inclination of the sleeve 11, due to the clippings 13 after the slider 12 has run thereon, is counteracted when the sleeve 11 is withdrawn. The inclined position of the sleeve 11 on the rail 10 results in a self-locking which prevents the slide 12 from retracting. Only when the toothed belt drive 16 picks up at the point of application in the release direction does the self-locking release and the clippings 13 are in the cutting area, e.g. for the feed, released. The slider 12 can be moved back to the position 12 '.

Der Träger 9 sitzt formschlüssig und unverschiebbar auf der Führungsstange 5, die an ihren Enden drehbar gelagert ist (Fig. 2). Ein Elektromotor 18 bewirkt die Verdrehung des Trägers 9 und damit der Schiene 10 zusammen mit der Hülse 11 und dem Schieber 12. Diese Verdrehung ist in Fig. 1 durch die strichlierte Lage des Trägers 9′ und der Schiene 10′ dargestellt. Im ausgeschwenkten Zustand kann der Schnittgutwagen 1 beladen werden.The carrier 9 sits positively and immovably on the guide rod 5, which is rotatably supported at its ends (Fig. 2). An electric motor 18 causes the rotation of the carrier 9 and thus the rail 10 together with the sleeve 11 and the slide 12. This rotation is shown in Fig. 1 by the broken line position of the carrier 9 'and the rail 10'. In the swung-out state, the clippings wagon 1 can be loaded.

Eine Steuerung 19 koordiniert die Ein- bzw. Umschaltung des Elektromotors 15 für den Riementrieb 16, des Elektromotors 18 für das Ein- und Ausschwenken der gesamten Abstützeinrichtung und verfügt über einen Ausgang 20 für den Reversierantrieb des Schnittgutwagens 1 und einen weiteren Ausgang 21 für den Vorschubantrieb des Schnittgutes 13.A controller 19 coordinates the switching on or switching over of the electric motor 15 for the belt drive 16, of the electric motor 18 for pivoting the entire support device in and out, and has an output 20 for the reversing drive of the clippings wagon 1 and a further output 21 for the feed drive the clippings 13.

Wenn ein Schnittgut 13 auf dem Schnittgutwagen 1 aufgelegt und der Schneidevorgang gestartet wird, aktiviert die Steuerung 19 vorerst den Vorschubantrieb für das Schnittgut 13, damit es in die Schneideposition gelangt. Sodann wird der Motor 15 über die Steuerung 19 eingeschaltet. In der mit vollen Linien in Fig. 1 gezeichneten Position des Schiebers 12 läuft dieser auf das Schnittgut 13 auf und blockiert den Motor 15, sodaß der Motorstrom steigt. Die Steuerung 19 stellt das Überschreiten eines voreinstellbaren Grenzwertes fest und schaltet die Motorspannung (z.B. 24 V) auf die schonende Haltespannung (z.B. 12 V) um. Damit drückt der Schieber 12 mit konstanter Kraft seitlich auf das Schnittgut 13 und hält dieses im Schnittbereich fest. Infolge der Toleranzen zwischen Hülse 11 und Schiene 10 kippt diese beim Auflaufen des Schiebers 12 auf das Schnittgut 13 und nimmt eine selbstklemmende Schräglage ein, die erst wieder beim Zurückfahren des Riementriebes 16 aufgehoben wird.When a clippings 13 is placed on the clippings wagon 1 and the cutting process is started, the controller 19 first activates the feed drive for the clippings 13 so that it reaches the cutting position. The motor 15 is then switched on via the controller 19. In the with full lines 1 drawn position of the slide 12 this runs onto the clippings 13 and blocks the motor 15, so that the motor current increases. The controller 19 detects that a preset limit value has been exceeded and switches the motor voltage (for example 24 V) to the gentle holding voltage (for example 12 V). Thus, the slider 12 presses laterally on the clippings 13 with constant force and holds them in the cutting area. As a result of the tolerances between the sleeve 11 and the rail 10, it tilts when the slider 12 runs onto the clippings 13 and assumes a self-locking inclined position, which is only released when the belt drive 16 moves back.

Nach dem Festklemmen des Schnittgutes in der Schnittebene schaltet die Steuerung 19 den Reversierantrieb für den Schneidevorgang ein. Nach jedem Hub wird die Klemmung des Schnittgutes 13 in der Schnittgutebene gelöst, so daß ein der Schnittstärke entsprechender Vorschub des Schnittgutes 13 erfolgen kann. Nach jedem Vorschub führt der Riementrieb 16 den Schieber 12 gegen das Schnittgut 13 in die selbstklemmende Position. Am Ende des Schneidevorganges führt die Steuerung 19 über den Motor 15 und den Zahnriementrieb 16 die Hülse 11 und damit den Schieber 12 zurück in die Position 12′ bzw. noch weiter weg vom Schnittgut 13 und aktiviert den Schwenkantrieb (Motor 18). Es wird die Schiene 10 bzw. die gesamte Abstützeinrichtung in die Position 10′ weggeschwenkt, wodurch die Auflagefläche des Schnittgutwagens 1 frei für das Auflegen eines neuen Schnittgutes 13 ist. Je nach Bauart kann auch auf einen Schwenkarm verzichtet werden.After the cut material has been clamped in the cutting plane, the control 19 switches on the reversing drive for the cutting process. After each stroke, the clippings of the clippings 13 are released in the clippings plane, so that the clippings 13 can be fed according to the cutting thickness. After each advance, the belt drive 16 guides the slider 12 against the clippings 13 into the self-locking position. At the end of the cutting process, the control 19 leads via the motor 15 and the toothed belt drive 16, the sleeve 11 and thus the slider 12 back into position 12 'or even further away from the clippings 13 and activates the swivel drive (motor 18). It is the rail 10 or the entire support device in the position 10 'pivoted away, whereby the support surface of the clippings wagon 1 is free for placing a new clippings 13. Depending on the design, a swivel arm can also be dispensed with.

Die Schiene 10 kann auch so ausgebildet sein, daß sie durch den Motor 18 bis zur Anlage auf dem Schnittgut 13 herabgeschwenkt werden kann. Dabei schaltet der Motor 18 strombegrenzt auf eine Haltespannung um. Beim Herabschwenken der Schiene 10 läuft der Schieber 12 auf der Auflagefläche des Schnittgutwagens 1 auf und weicht entgegen Federkraft in einer Führung der Hülse 11 zurück. Über den Antrieb 15 und den Zahnriementrieb 16 erfolgt der Vorschub des Schiebers 12 in die Halteposition. Die Schwenklage der Schiene 10 und bzw. oder wie bei der Ausführung nach Fig. 1, ist die Stellung des Schiebers 12 ein Maß für die Größe des Schnittgutes (z.B. den Durchmesser einer Wurst im Schnittbereich). Stellungsmelder 22 zählen die Impulse des Antriebsmotors 15 bis zum Klemmen des Schnittgutes 13 und führen diesen Wert als Maßzahl für die Schnittgutgröße einer Steuerung für das Ablegesystem zu.The rail 10 can also be designed so that it can be pivoted down by the motor 18 to rest on the clippings 13. The motor 18 switches to a holding voltage in a current-limited manner. When the rail 10 is pivoted down, the slide 12 runs on the support surface of the clippings wagon 1 and backs away against the spring force in a guide of the sleeve 11. Via the drive 15 and the toothed belt drive 16, the slide 12 is fed into the holding position. The pivot position of the rail 10 and / or as in the embodiment according to FIG. 1, the position of the slide 12 is a measure of the size of the material to be cut (for example the diameter a sausage in the cutting area). Position indicators 22 count the pulses of the drive motor 15 until the clippings 13 are clamped and supply this value as a measure of the clippings size to a controller for the depositing system.
