- the clippings wagon 2 has the shape of a channel with a base-side support surface 8 which is delimited by the side walls 9, 10 (FIG. 5).
- Support surface 8 and side walls 9, 10 are made in one piece from stainless steel sheet.
- the seamless training is particularly advantageous in terms of hygiene.
- Drive elements are each provided in the form of a belt drive 11, 12 in the side walls 9, 10 (FIG. 3).

- a controller 22 is connected upstream of the electric motor 14.
- the electric motor 14 is controlled in the exemplary embodiment to a constant speed, so that the slide 19 continues at the same feed speed when it comes from the basic position at the rear end of the clippings wagon, reaches the clippings 21 and advances them.
- the electronic circuit 22 for regulating the electric motor 14 also provides a threshold value generator for the rotational speed of the electric motor 14, if this threshold value is exceeded, for example, by the cut material 21 hitting an obstacle, such as the stop plate 3, then the electric motor 14 is switched off. Then a feed takes place accordingly the cutting thickness set on the cutting thickness switch 23 with each stroke of the clippings wagon 2, that is to say shortly before each cutting process.
- the feed of the material to be cut 21 can be limited by the position of the stop plate to ensure the desired cutting thickness, but it can also move the stop plate further than the cutting thickness. Then the cutting thickness is determined solely by the exact advance of the material to be cut, which can be done very precisely by the electric motor 14 in the creeping process.
- a device for fixing the cut material in the cutting area can be provided.
- the machine control 24 issues the command to the electric motor 14 to reset the slide 19 to the starting position shown in FIG , so that the cutting edge of the knife disc 4 is covered and there is no risk of injury.
- the machine control 24 switches on the electric motor 14, which pushes the clippings into the cutting position by means of the slide 19 .

- the electric motor 14 is briefly activated and the clippings 21 are advanced by the measure of the cutting thickness (arrows 28).
- the feed can also take place against the stop plate 3 and, due to this obstacle and the resulting drop in speed of the electric motor, that is to say when the threshold value of the controller 22 is undershot, the electric motor 14 can switch off automatically in each case.
- the command for reversing the electric motor 14 and for switching on the servo motor 25 for resetting the stop plate 3 into the plane of the knife disk 4 can be given via the machine control 24.
- Fig. 2 shows rollers 29 on the support surface 8, which reduce the friction of the clippings 21 during feed.
- the rollers can be encased in a rectangular frame which is designed as a separate component which can be removed from the support surface 8.

Description
Die Erfindung betrifft eine Aufschnittschneidemaschine mit einer Messerscheibe, einem Schnittgutwagen, und einem ersten, automatische Antrieb zum hin- und hergehenden Bewegen des Schnittgutwagens längs der Messerscheibe, wobei der Schnittgutwagen eine selbsttätige Schnittgutzuführung durch Vorschub des Schnittgutes auf einer Auflagefläche des Schnittgutwagens aufweist, wobei die Schnittgutzuführung einen die Auflagefläche überbrückenden Schieber und einen zweiten Antrieb aufweist, der zum schrittweisen Vorschub des Schiebers in Richtung auf die Messerscheibe geeignet ist.The invention relates to a slicing machine with a knife disc, a clippings wagon, and a first, automatic drive for reciprocating movement of the clippings wagon along the knife disc, the clippings wagon having an automatic clippings feed by advancing the clippings on a support surface of the clippings wagon, the clippings feeder has a slide bridging the bearing surface and a second drive which is suitable for the gradual advancement of the slide in the direction of the knife disc.
Bei automatischen Aufschneidemaschinen wird das Schnittgut meist selbstätig vorgeschoben. Dazu sind Schnittguthalter vorgesehen, die längs einer Führungsstange auf dem Schnittgutwagen laufen und von einem Antrieb vorgeschoben bzw. zurückgezogen werden. Zur Positionierung, also zum Vorschub in die Schneideposition kann ein Eilgang und für den Vorschub beim Schneidevorgang ein Schleichgang vorgesehen sein.In automatic slicers, the clippings are usually fed automatically. For this purpose, clippings holders are provided, which run along a guide rod on the clippings wagon and are advanced or withdrawn by a drive. A rapid traverse can be provided for positioning, that is to say for advancing into the cutting position, and a creeping trajectory can be provided for advancing during the cutting process.
Aus der US-A-2 096 212 ist ein Kreuzschlittensystem bei Aufschnittschneidemaschinen bekannt. Auf einem Schnittgutwagen, der längs der Messerscheiben reversierend angetrieben ist, bewegt sich ein Schieber in Richtung auf die Messerscheibe und führt dadurch das Schnittgut der Messerscheibe zu. Der Antrieb des Schnittgutwagens sowie der Antrieb zum Vorschub des Schnittgutes mittels des Schiebers erfolgen mechanisch. Der Schieber wird von einer mittig angeordneten Spindel vorgeschoben. Durch eine außermittige Positionierung des Schnittgutes auf dem Schnittgutwagen kann der Schieber verkanten. Bei einer anderen Ausführung kragt ein Schnittguthalter von der Seite über die Auflagefläche des Schnittgutes, sodaß es zu Asymmetrie beim Vorschub, zu Schrägstellungen und zum Klemmen der Führungen kommen kann.From US-A-2 096 212 a cross slide system in slicing machines is known. On a clippings wagon, which is reversibly driven along the cutting discs, a slide moves in the direction of the cutting disc and thereby feeds the clippings to the cutting disc. The drive of the clippings wagon and the drive for feeding the clippings by means of the slide are done mechanically. The slide is pushed forward by a central spindle. The slide can tilt due to an off-center positioning of the clippings on the clippings wagon. In another embodiment, a clippings holder protrudes from the side over the contact surface of the clippings, so that asymmetry in the feed, inclined positions and jamming of the guides can occur.
Die Erfindung zielt darauf ab, diese Nachteile zu beseitigen und einen Schnittgutwagen der eingangs beschriebenen Art so auszustatten, daß die Krafteinwirkung auf das Schnittgut symmetrisch erfolgt. Dies wird dadurch erreicht, daß der Schnittgutwagen der eingangsgenannten Aufschnittschneidemaschine zum Vorschub des Schnittgutes beiderseits der Auflagefläche für das Schnittgut jeweils miteinander synchronisierte Antriebselemente, insbesondere je einen Zahnriementrieb mit einem gegebenenfalls gemeinsamen Elektromotor als Antrieb für den die Auflagefläche überbrückenden Schieber aufweist. Infolge der synchronisierten Antriebselemente und der symmetrischen Krafteinwirkung auf das Schnittgut erfolgt auch unter Last ein störungsfreier Vorschub und ein exakter Schneidevorgang. Der zwischen den beiden Antriebselementen (Zahnriemen) auf Mitnehmern links und rechts an seinen Enden lösbar gelagerte, die Ablagefläche überbrückende Schieber, kann zur Reinigung leicht abgenommen werden. Es ist zweckmäßig, wenn der Schnittgutwagen als einstückige, gegen die Messerscheibe gerichtete Rinne mit Auflagefläche und mit parallelen Seitenwänden ausgebildet ist, in deren Innerem die Antriebselemente, insbesondere die Zahnriementriebe, vorgesehen sind. Die Auflagefläche geht einstückig in die randseitigen Seitenwände über. Die gesamte Baueinheit kann aus einem Stück eines rostfreien Stahlbleches gebogen werden und daher fugenlos ausgebildet sein; dies ist im Hinblick auf die Hygiene und den Reinigungsvorgang von ganz besonderem Vorteil. Zur Reinigung wird der Schnittgutwagen um eine horizontale, parallel zu seiner Bewegungsrichtung seitlich an der Maschine angeordnete Achse hochgekippt und mit einem üblichen Dampfstrahlgerät behandelt.The invention aims to eliminate these disadvantages and to equip a clippings wagon of the type described in the introduction in such a way that the force exerted on the clippings takes place symmetrically. This is achieved in that the Cutter car of the above-mentioned slicing machine for feeding the cuttings on both sides of the support surface for the cuttings each has synchronized drive elements, in particular a toothed belt drive each with a possibly common electric motor as a drive for the slide bridging the support surface. As a result of the synchronized drive elements and the symmetrical application of force to the clippings, there is a trouble-free feed and an exact cutting process even under load. The slide between the two drive elements (toothed belt), which is detachably mounted at the ends on the left and right at drivers, bridging the storage surface, can be easily removed for cleaning. It is expedient if the clippings wagon is designed as a one-piece channel directed against the cutter disc with a support surface and with parallel side walls, inside which the drive elements, in particular the toothed belt drives, are provided. The contact surface merges in one piece into the side walls on the edge. The entire assembly can be bent from a piece of stainless steel sheet and can therefore be designed without joints; this is of particular advantage in terms of hygiene and the cleaning process. For cleaning, the clippings wagon is tipped up around a horizontal axis, which is arranged on the side of the machine parallel to its direction of movement, and treated with a conventional steam jet device.
Eine spezielle Ausführungsform sieht vor, daß unterhalb der Auflagefläche der Elektromotor vorgesehen ist, der über ein Getriebe eine Antriebswelle antreibt, deren beide Enden mit Umlenkrollen jeweils eines Zahnriemenantriebes verbunden ist. Es ist zweckmäßig, wenn dem Elektromotor ein Regler vorgeschaltet ist, der bei lastseitiger Geschwindigkeitsänderung und Unterschreiten eines Schwellenwertes, insbesonders bei Auflaufen des Schiebers bzw. des vorgeschobenen Schnittgutes auf ein Hindernis wie etwa die Anschlagplatte oder die Hand einer Bedienungsperson, der Elektromotor abschaltbar ist. Es kann ein Schnittgut an beliegiger Stelle auf die Auflagefläche des Schnittgutwagens aufgelegt werden. Nach Einschalten der Maschine fährt der Schieber aus seiner zur Gänze zurückgeschobenen Position in Richtung auf die Anschlagplatte. Dabei gelangt er in Berührung mit dem Schnittgut und nimmt es zur Anschlagplatte mit. Der Motor ist geschwindigkeitsgeregelt, das heißt , er wird bis zu einer Grenzschwelle auf konstante Geschwindigkeit gebracht. Wird aber dieser Schwellenwert unterschritten, dann schaltet die Steuerung bzw. der Regler den Elektromotor ab. Auf diese Weise ist es möglich, das Schnittgut etwa im Eilgang bis in die Schneideposition zu führen. Während des Schneidevorganges, also während der Hubbewegung des Schnittgutwagens,erfolgt der Vorschub des Schnittgutes präzise jeweils um die Schnittstärke bzw. bis zur Anschlagplatte. Es ist zweckmäßig, wenn auf der Auflagefläche Rollen bzw. Walzen zum reibungsverminderten Vorschub, insbesonders ein entnehmbarer Rahmen mit Rollen oder Walzen, vorgesehen sind. Eine als Rahmen ausgebildete Baueinheit mit Rollen kann als separater Bauteil von der Auflagefläche des Schnittgutwagens entnommen und separat gereinigt werden.A special embodiment provides that below the support surface the electric motor is provided, which drives a drive shaft via a gearbox, the two ends of which are connected to deflection rollers of a toothed belt drive. It is expedient if the electric motor is preceded by a controller which, when the speed changes at the load and falls below a threshold value, in particular when the slide or the cut material being pushed onto an obstacle such as the stop plate or the hand of an operator, the electric motor can be switched off. A clippings can be placed on the support surface of the clippings wagon at any point. After switching on the machine drives the slide from its fully retracted position towards the stop plate. It comes into contact with the clippings and takes them to the stop plate. The motor is speed-controlled, which means that it is brought to constant speed up to a limit threshold. If, however, the temperature falls below this threshold, the controller or controller switches off the electric motor. In this way it is possible to move the clippings to the cutting position in rapid traverse. During the cutting process, that is to say during the lifting movement of the clippings wagon, the clippings are advanced precisely by the cutting thickness or up to the stop plate. It is expedient if rollers or rollers for friction-reduced feed, in particular a removable frame with rollers or rollers, are provided on the support surface. A structural unit with rollers designed as a frame can be removed as a separate component from the support surface of the clippings wagon and cleaned separately.
Ein Ausführungsbeispiel ist in den Zeichnungen schematisch dargestellt. Fig. 1 zeigt eine Draufsicht auf eine Aufschnittschneidemaschine in ihren Grundzügen mit einem Schnittgutwagen gemäß der Erfindung, Fig. 2 einen Schnittgutwagen nach der Linie II-II in Fig. 1, Fig. 3 einen Schnitt nach der Linie III-III in Fig. 2, Fig. 4 eine Ansicht des Schnittgutwagens von unten und Fig. 5 eine Schrägrißdarstellung des Schnittgutwagens von der Anschlagplatte aus gesehen.An embodiment is shown schematically in the drawings. 1 shows a plan view of a slicing machine in its basic features with a clippings wagon according to the invention, FIG. 2 shows a clippings wagon along the line II-II in FIG. 1, FIG. 3 shows a section along the line III-III in FIG. 2 4 shows a view of the clippings wagon from below, and FIG. 5 shows an oblique view of the clippings wagon from the stop plate.
Eine Aufschnittschneidemaschine nach Fig. 1 umfaßt einen Gehäuserahmen 1 auf dem ein Schnittgutwagen 2 längs einer Anschlagplatte 3 und einer Messerscheibe 4 durch einen als erster automatischer Antrieb bezeichneter Reversierantrieb 27 in Richtung der Pfeile 2' hin und her verschiebbar ist. Eine geschnittene Scheibe gelangt in bekannter Weise über Förderketten 5 auf ein Ablegetablett 6. Der Schnittgutwagen 2 sitzt auf einem Träger (nicht dargestellt) der im Gehäuse durch einen Riementrieb, Kurbeltrieb oder eine Spindel über einen Elektromotor angetrieben wird. Der Schnittgutwagen ist nach Lösen einer Verriegelung gegenüber dem Träger um eine Achse, die mit der Schnittlinie II-II in Fig. 1 etwa zusammenfällt, kippbar. Wie Fig. 2 zeigt, hat der Schnittgutwagen 2 die Form einer Rinne mit einer bodenseitigen Auflagefläche 8, die von den Seitenwänden 9, 10 begrenzt wird (Fig. 5). Auflagefläche 8 und Seitenwände 9, 10 sind einstückig aus rostfreiem Stahlblech gefertigt. Die fugenlose Ausbildung ist im Hinblick auf die Hygiene besonders vorteilhaft. In den Seitenwänden 9, 10 sind Antriebselemente jeweils in Form eines Riementriebes 11, 12 vorgesehen (Fig. 3). Die Riementriebe 11, 12 liegen auf einer unterhalb der Auflagefläche 8 angeordneten, gemeinsamer Achse 13 (Fig. 4) und werden von einem als zweiter Antrieb bezeichneten Elektromotor 14 über ein Getriebe synchron angetrieben. Jeder Riementrieb 11, 12 trägt einen Mitnehmer 15, 16. In diesen greift ein beiderseits vorgesehenes Kupplungsstück 17, 18 ein, das starr mit einem Schieber 19 verbunden ist. Der Schieber 19 ist längs der Seitenwände 9, 10 geführt und wird von den Riementrieben 11, 12 über die Mitnehmer 15, 16 und die Kupplungsstücke 17, 18 in Längsrichtung des Schnittgutwagens 2 je nach Drehrichtung des Elektromotors 14 vorlaufend oder rücklaufend mitgenommen. Der Schieber 19 verfügt über eine Stirnplatte 20, die mit Spitzen besetzt ist. Ein Schnittgut 21 wird gemäß Fig. 1 von dem in Richtung zur Anschlagplatte 3 angetriebenen, vorlaufenden Schieber 19 bzw. dessen Stirnplatte 20 erfaßt und um Eilgang gegen die Anschlagplatte 3 geschoben. Ein Regler 22 ist dem Elektromotor 14 vorgeschaltet. Der Elektromotor 14 wird im Ausführungsbeispiel auf konstante Drehzahl geregelt, sodaß der Schieber 19 mit gleicher Vorschubgeschwindigkeit weiterfährt, wenn er aus der Grundstellung am hinteren Ende des Schnittgutwagens kommend, das Schnittgut 21 erreicht und dieses vorschiebt. Die elektronische Schaltung 22 zur Regelung des Elektromotors 14 sieht ferner einen Schwellenwertgeber der Drehzahl des Elektromotors 14 vor, wenn dieser Schwellenwert etwa durch Auflaufen des Schnittgutes 21 auf ein Hindernis, wie die Anschlagplatte 3, unterschritten wird, dann wird der Elektromotor 14 abgeschaltet. Danach erfolgt ein Vorschub entsprechend der am Schnittstärkeschalter 23 eingestellten Schnittstärke bei jedem Hub des Schnittgutwagens 2, also kurz vor jedem Schneidevorgang. Der Vorschub des Schnittgutes 21 kann zur Gewährleistung der gewünschten Schnittstärke durch die Position der Anschlagplatte begrenzt werden, es kann aber auch die Anschlagplatte weiter als der Schnittstärke entsprechend zurückfahren. Dann wird die Schnittstärke allein durch den exakten Vorschub des Schnittgutes, der im Schleichvorgang sehr präzise über den Elektromotor 14 erfolgen kann, bestimmt. Eine Vorrichtung zur Lagefixierung des Schnittgutes im Schnittbereich kann vorgesehen sein. Nach Ende eines Aufschneidevorganges gibt die Maschinensteuerung 24 den Befehl an den Elektromotor 14 zum Zurückstellen des Schiebers 19 in die Ausgangsposition nach Fig. 1. Ferner wird ein elektrischer Servoantrieb 25 für die Anschlagplatte 3 eingeschaltet, der die Anschlaplatte 3 in die Ebene der Messerscheibe 4 vorschiebt, sodaß die Schneidekante der Messerscheibe 4 abgedeckt ist und keine Verletzungsgefahr besteht.1 comprises a
Die Maschinensteuerung 24 schaltet nach Auflegen des Schnittgutes, Einstellen der Schnittstärke am Schnittstärkeschalter 23 und des Ablegeprogrammes (Stapeln, Fächern, konzentrische Kreise usw.) sowie nach Betätigen einer Starttaste 26 den Elektromotor 14 ein, der das Schnittgut mittels des Schiebers 19 in die Schneideposition vorschiebt. Der Servomotor 25 fährt die Anschlagplatte 3 z.B. dabei um das Maß der eingestellten Schnittstärke zurück. Der Hauptantrieb 26 für die Messersch be 4 und der Antrieb 27 für den Schnittgutwagen 2 in Richtung der Pfeile 2' wird eingeschaltet. Vor jedem Hub des Schnittgutwagens 2 gegen die Messerscheibe 4 wird der Elektromotor 14 kurz aktiviert und das Schnittgut 21 um das Maß der Schnittstärke vorgeschoben (Pfeile 28). Der Vorschub kann auch jeweils gegen die Anschlagplatte 3 erfolgen und aufgrund dieses Hindernisses und des dadurch bedingten Drehzahlabfalles des Elektromotors, also bei Unterschreiten des Schwellenwertes des Reglers 22, kann der Elektromotor 14 jeweils selbsttätig abschalten. Wenn das gewünschte Ablegeprogramm durchlaufen oder ein Schnittgut zur Gänze aufgeschnitten ist, dann kann über die Maschinensteuerung 24 der Befehl zum Reversieren des Elektromotors 14 und zum Einschalten des Servomotors 25 zur Rückstellung der Anschlagplatte 3 in die Ebene der Messerscheibe 4 erfolgen.After placing the clippings, setting the slice thickness at the
Fig. 2 zeigt Walzen 29 auf der Auflagefläche 8, die die Reibung des Schnittgutes 21 beim Vorschub vermindern. Die Walzen können in einem Rechteckrahmen gelangert sein, der als separater, von der Auflagefläche 8 entnehmbarer Bauteil ausgebildet ist.Fig. 2 shows
