Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft eine Schneidmaschine, mit der sich Brot, Käse und dergleichen strangförmige Lebensmittel in beliebig dicke Scheiben maschinell schneiden lassen.The invention relates to a cutting machine with which bread, cheese and the like string-shaped food can be cut into any desired thicknesses by machine.

STAND DER TECHNIKSTATE OF THE ART

Aus der DE 198 20 004 C2 ist eine gattungsgemäße Maschine der eingangs genannten Art zum Schneiden eines Gutsstranges in Scheiben bekannt. Diese Schneidmaschine besitzt ein kreisförmiges Schneidmesser, das um seine zentrale Achse rotieren und zusätzlich in einer Kreisbahn umhergeschwenkt werden kann. Bei dieser Schwenkbewegung wird es durch das in Scheiben zu schneidende strangförmige Lebensmittel hindurchgeführt. Das strangförmige Lebensmittel wird in einem kanalartigen Schacht dem Schneidmesser zugeführt und in Scheiben zerschnitten. Die geschnittenen Scheiben werden auf einer dem Schneidmesser in Förderrichtung nachgeordneten Lagerfläche stehend gespeichert. Das Lebensmittel ist also vor und nach seinem Zerschneiden als Strang vorhanden mit dem Unterschied, dass der Strang nach dem Zerschneiden sich aus entsprechend vielen Scheiben zusammensetzt.From the DE 198 20 004 C2 is a generic machine of the type mentioned for cutting a Gutsstranges in slices known. This cutting machine has a circular cutting blade, which rotate about its central axis and can also be swung around in a circular path. In this pivoting movement, it is passed through the sliced food to be cut in slices. The rope-shaped food is supplied to the cutting blade in a channel-like shaft and cut into slices. The cut slices are stored standing on a downstream of the cutting blade in the conveying direction bearing surface. The food is therefore present as a strand before and after its cutting with the difference that the strand after cutting composed of correspondingly many slices.

Das Schneiden selber erfolgt ohne Zuführen von Öl. Dies birgt die Gefahr, dass Bestandteile des Lebensmittels an dem Schneidmesser haften bleiben können, was die Qualität des Schnittes beeinträchtigt. Um dieser Gefahr zu begegnen ist bei dieser vorbekannten Schneidmaschine der Boden, auf dem die geschnittenen Scheiben auflagern, in Förderrichtung geneigt ausgebildet gegenüber dem kanalartigen Boden, auf dem das ungeschnittene, noch als Strang vorhandene Lebensmittel während seines Zuführens zu dem Schneidmesser aufruht. Durch diese abgewinkelte Ausrichtung der Lagerfläche für die geschnittenen Scheiben gegenüber der Lagerfläche für den noch nicht geschnittenen Strang soll erreicht werden, dass die jeweils geschnittene Brotscheibe von dem Schneidmesser wegkippt und dadurch möglichst nicht am Schneidmesser anhaften bleibt. Zur Sicherstellung dieses Effektes ist es an sich seit langem bekannt, die den geschnittenen Scheiben zugewandte Fläche des Schneidmessers leicht keilförmig auszubilden. Allerdings lässt sich durch diese winkelförmige Ausbildung der Lagerflächen für das zu schneidende Lebensmittel nicht verhindern, dass die jeweils geschnittene Scheibe gegenüber dem Lebensmittelstrang seitlich wegkippt und schräg zu demselben nach dem Schneidvorgang vorhanden ist. Dadurch lässt sich ein schuppenartiges Aneinanderliegen der geschnittenen Scheiben nicht vollständig verhindern.The cutting itself is done without supplying oil. This entails the risk that constituents of the food may adhere to the cutting blade, which impairs the quality of the cut. In order to counteract this risk, in this prior art cutting machine the bottom on which the cut slices are mounted is inclined in the conveying direction relative to the channel-like bottom on which the uncut foodstuff still rests during its feeding to the cutting knife. By this angled orientation of the bearing surface for the cut slices relative to the bearing surface for the not yet cut strand is to be achieved that the sliced bread slice tilts away from the cutting blade and thus does not stick as possible to the cutting blade. To ensure this effect, it has long been known that the sliced facing surface of the cutting blade slightly wedge-shaped form. However, this angular design of the bearing surfaces for the food to be cut does not prevent the respective cut slice from tilting laterally with respect to the food strand and being present at an angle to it after the cutting process. As a result, a scale-like abutment of the cut slices can not be completely prevented.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Scheibenschneidmaschine der eingangs genannten Art anzugeben, mit der sich qualitätsmäßig gute Ergebnisse erzielen lassen und die sich auch in ihrer Bedienung und Wartung möglichst einfach dem Bediener darstellt.Based on this known prior art, the present invention seeks to provide a slicing machine of the type mentioned above, with the quality results can be achieved and is as simple as possible to the operator in their operation and maintenance.

Die erfindung ist im Anspruch 1 definiert.The invention is defined in claim 1.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass die Lagerfläche für die geschnittenen Scheiben und die Lagerfläche für den noch nicht in Scheiben geschnittenen Lebensmittel-Strang in einer Ebene liegen und nicht abgeknickt sind, dass aber die Ausrichtung dieser beiden Lagerflächen schräg im Raum, aber mit gleichem Neigungswinkel, ausgerichtet ist. Das Schneidmesser ist senkrecht zu den beiden Lagerflächen ausgerichtet. Diese in Fallrichtung geneigte Ausrichtung der Lagerflächen, auf der das strangförmige Lebensmittel der Schneidvorrichtung zugeführt wird und auf der es die Schneideinrichtung in Scheibenform verlässt, hat den Vorteil, dass die jeweils geschnittene Scheibe weniger stark nach ihrem Zerschneiden an dem Schneidmesser anliegt, als wenn sie senkrecht stehend ausgerichtet wäre. Trotzdem kann der noch einteilig vorhandene Lebensmittel-Strang bei seinem Bewegen in Richtung auf das Schneidmesser zu und durch dasselbe hindurch vollflächig gegen die bereits geschnittene Scheibe drücken. Ein gegenseitiges räumliches, schuppenförmiges Versetzen zwischen der noch nicht geschnittenen Stirnseite des Lebensmittel-Stranges und den bereits geschnittenen Scheiben findet dadurch nicht statt. Das strangförmige Lebensmittel wird ohne Versatz nach unten oder zur Seite in Scheiben durchtrennt, ohne dass die Strangform dabei verloren geht.According to a preferred embodiment, it is provided that the bearing surface for the cut slices and the bearing surface for the not yet sliced food strand are in a plane and not kinked, but that the orientation of these two bearing surfaces obliquely in space, but with the same Tilt angle, is aligned. The cutting blade is aligned perpendicular to the two bearing surfaces. This inclined in the fall direction orientation of the bearing surfaces on which the strand-shaped food is supplied to the cutting device and on which it leaves the cutter in disc form, has the advantage that the respective cut disc rests less strongly after their cutting on the cutting blade, as if vertically would be aligned standing. Nevertheless, when still moving in the direction of the cutting blade, the food strand, which is still in one piece, can press against the already cut slice to and through the entire surface. A mutual spatial, scale-like displacement between the not yet cut end side of the food strand and the already cut slices does not take place. The strand-shaped food is cut without offset downwards or sideways into slices, without losing the strand shape is lost.

Es hat sich herausgestellt, dass durch ein Vibrieren des Schneidmessers und durch ein Vibrieren der Lagereinrichtung für die geschnittenen Scheiben sich der Effekt verstärken lässt, dass sich die jeweils geschnittene Scheibe leicht von dem Schneidmesser löst und nicht an demselben anhaftet.It has been found that by vibrating the cutting blade and vibrating the sliced disk bearing device, it is possible to enhance the effect that the respective cut disk easily separates from and does not adhere to the cutting blade.

Eine weitere bevorzugt erfindungsgemäße Lösung, um das Anhaften von geschnittenen Scheiben an dem Schneidmesser zu verhindern, ist erfindungsgemäß dadurch gegeben, dass die Lagerfläche für die geschnittenen Scheiben ein endlos umlaufendes Transportband besitzt. Durch Antreiben insbesondere taktweises Antrieben dieses Transportbandes kann das Wegbewegen der jeweils geschnittenen Scheibe und damit auch der insgesamt geschnittenen Scheiben weg von der Schneideinrichtung aktiv gefördert werden.Another preferred solution according to the invention to prevent the adhesion of cut slices on the cutting blade, according to the invention is given by the fact that the storage area for the cut slices has an endless circulating conveyor belt. By driving in particular cyclically driving this conveyor belt, the moving away of each cut slice and thus also the total cut slices away from the cutting device can be actively promoted.

Die vorstehend erwähnte Relativbewegung zwischen Schneidmesser und geschnittenen Scheiben kann nach einer weiteren erfindungsgemäßen Lösung wie folgt bewirkt werden. Der Transportschieber, der an dem Lebensmittel-Strang hinten angreift und den Strang in Richtung Schneidmesser bewegt, greift zug- und druckfest an dem Lebensmittel-Strang an. Während des taktweisen Transportes des Transportschiebers in Richtung Schneidmesser wird der Lebensmittel-Strang entsprechend taktweise durch die Schneideinrichtung und damit an dem Schneidmesser vorbeigeführt. Es kann nun erfindungsgemäß vorgesehen werden, den Transportschieber auch in Gegen-Förderrichtung verfahrbar auszubilden, damit er bei seiner Bewegung in Gegen-Förderrichtung den Lebensmittelstrang ebenfalls in Gegen-Förderrichtung ein Stück weit zurücknehmen kann. Dadurch wird der Druck, mit dem der Lebensmittelstrang an dem Schneidmesser anliegt und damit auch der Druck, mit dem er an den geschnittenen Scheiben drückend anliegt, vermindert.The above-mentioned relative movement between the cutting blade and cut slices can be effected according to a further solution according to the invention as follows. The transport slider, which engages behind the food strand and moves the strand in the direction of the cutting blade, acts on the food strand in a manner that is resistant to tension and pressure. During the cyclic transport of the transport slide in the direction of the cutting blade, the food strand is passed cyclically through the cutting device and thus on the cutting blade accordingly. It can now be inventively provided to form the transport slide movable in the counter-conveying direction, so that he can take back the food strand in its counter-conveying direction also in the counter-conveying direction a piece far. As a result, the pressure with which the food strand rests against the cutting blade and thus also the pressure with which it presses against the cut disks is reduced.

Um zu verhindern, dass die geschnittenen Scheiben in Förderrichtung umfallen, was durch die geneigte Ausrichtung der Lagerflächen sonst der Fall wäre, kann nach einer weiteren erfindungsgemäßen Lösung eine Halteeinrichtung für die geschnittenen Scheiben des Lebensmittel-Stranges vorgesehen werden. Diese Halteeinrichtung, gegen die sich der geschnittene Scheibenstrang anlehnen kann, kann taktweise verfahren werden. Dadurch braucht nicht unbedingt der noch nicht in Scheiben geschnittene Lebensmittel-Strang zum Verschieben der geschnittenen Scheiben benutzt zu werden. Im Ergebnis werden die geschnittenen Scheiben mit geringerer Druckbelastung beaufschlagt, was der Schnittfläche und damit der Qualität der Scheibenoberfläche zugute kommt.In order to prevent the cut slices falling over in the conveying direction, which would otherwise be the case due to the inclined orientation of the bearing surfaces, according to a further inventive solution, a holding device for the sliced slices of the food strand can be provided. This holding device, against which the cut disk strand can lean, can be moved intermittently. This does not necessarily use the not yet sliced food strand to move the cut slices. As a result, the cut discs are subjected to a lower pressure load, which benefits the cut surface and thus the quality of the disc surface.

Die geneigte Ausrichtung der Lagerflächen für das in Scheiben zu schneidende strangförmige Lebensmittel hat den Vorteil, dass das Schneidmesser leicht gekippt angeordnet werden kann. Die Drehachse des Schneidmessers verläuft in aller Regel parallel zu den Lagerflächen, so dass die kreisförmige Fläche des Schneidmessers und damit die Achse leicht schräg nach oben sich einer in die Maschine hineinbückenden Bedienperson sehr bedienungsfreundlich entgegenstreckt. Diese Zugänglichkeit zu der Schneideinrichtung wird noch dadurch wesentlich erleichtert, und das gilt grundsätzlich für alle Ausrichtungen einer solchen Schneideinrichtung, dass die Vorderwand der Schneidmaschine, das heißt die Vorderwand des Gehäuses dieser Scheibenschneidmaschine, leicht entfernbar ist. Nach dem in der Zeichnung dargestellten Ausführungsbeispiel kann die Vorderwand des Gehäuses der entsprechenden Scheibenschneidmaschine im Bereich der Lagerflächen, in der das Lebensmittel noch strangförmig ungeschnitten vorhanden ist, sogar zusammen mit diesen Lagerflächen entfernt werden. Diese entfernten Teile bestehen einmal aus der Frontseite des Auffangbehälters für Krümel, der regelmäßig bei solchen Scheibenschneidmaschinen vorhanden ist, und gegebenenfalls ferner auch aus einem Gehäuseteil, das einteilig mit den Lagerflächen im Bereich des noch nicht geschnittenen strangförmigen Lebensmittels verbunden ist. Durch Wegnehmen dieser oberen Vorderwand kann dann gleichzeitig auch die Lagerfläche in dem Zuführbereich zu dem Schneidmesser mit entfernt werden. Dadurch lässt sich eine besonders große Öffnung und damit eine leichte Zugänglichkeit zu dem Schneidmesser der Schneideinrichtung schaffen.The inclined orientation of the bearing surfaces for the sliced food to be sliced has the advantage that the cutting blade can be easily tilted. The axis of rotation of the cutting blade usually runs parallel to the bearing surfaces, so that the circular surface of the cutting blade and thus the axis slightly obliquely upwards extends an operator hunched into the machine very easy to use. This accessibility to the cutting device is still greatly facilitated thereby, and this is true in principle for all orientations of such a cutting device that the front wall of the cutting machine, that is, the front wall of the housing of this disc cutting machine is easily removable. According to the embodiment shown in the drawing, the front wall of the housing of the corresponding disc cutting machine in the region of the bearing surfaces, in which the food is still present strandless uncut, even be removed together with these bearing surfaces. These removed parts once consist of the front of the container for crumbs, which is regularly present in such slicing machines, and optionally also of a housing part which is integrally connected to the bearing surfaces in the region of the not yet cut strand-shaped food. By removing this upper front wall can then be removed at the same time also the bearing surface in the feed to the cutting blade. As a result, a particularly large opening and thus easy accessibility to the cutting blade of the cutting device can be created.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Die in Fig. 1 dargestellte Scheibenschneidmaschine 10 ist im vorliegenden Beispielsfall zum Schneiden von insbesondere Brot ausgebildet. Die danach dargestellte Brotschneidmaschine 10 besitzt ein äußeres Gehäuse 12 mit einem etwa rechteckigen Grundriss. Das Gehäuse 12 ruht auf vier Doppelrollen 14 auf, so dass es leicht hin und her verschoben werden kann.In the Fig. 1 illustrated slicing machine 10 is formed in the present example case for cutting bread in particular. The bread slicer 10 shown thereafter has an outer housing 12 with an approximately rectangular floor plan. The housing 12 rests on four double rollers 14, so that it can be easily moved back and forth.

Zur Sicherheit kann die Brotschneidmaschine 10 durch einen Schiebedeckel 16, der durch einen Griff 18 ähnlich einem Rollladen hin und her geschoben werden kann, verschlossen werden. In den Fig. 1 und 2 ist der Schiebedeckel 16 zurückgeschoben, so dass ein Brot in die Brotschneidmaschine 10 eingelegt beziehungsweise die geschnittenen Scheiben entnommen werden können.For safety, the bread slicer 10 can be closed by a sliding lid 16, which can be pushed back and forth by a handle 18 similar to a roller shutter. In the Fig. 1 and 2 the sliding lid 16 is pushed back so that a bread can be inserted into the bread slicer 10 or the cut slices can be removed.

Im Inneren der Brotschneidmaschine 10 ist eine rückwärtige Führungswand 20 vorhanden, die die Rückseite eines das zu zerschneidende Brot aufnehmenden Kanals bildet. Der Kanalboden 22 ist nur in seinem in Fig. 1 linken Bereich dargestellt. In dem - bezogen auf die Fig. 1 - rechten Bereich ist dieser Kanalboden 22, der in Fig. 2 mit dem Bezugszeichen 22.2 bezeichnet ist, aus dem Gehäuse 12 herausgenommen, wie dies später näher beschrieben wird. Der gesamte Kanalboden 22 (22.2) ist leicht geneigt vorhanden, so dass das geschnittene beziehungsweise zu schneidende Lebensmittel einerseits auf dem Kanalboden 22 (22.2) und andererseits an der vorderen Kanalwand 24 beziehungsweise 24.2 anliegt. Der Neigungswinkel 25 liegt vorzugsweise zwischen 5 Grad und 50 Grad und liegt im vorliegenden Beispielsfall etwa zwischen 5 Grad und 15 Grad. Kanalboden und Kanalwand sind etwa rechtwinklig zueinander ausgerichtet. Dies bedeutet, dass die Kanalwand 24, 24.2 von der Vorderseite her in das Innere des Gehäuses 12 hineingeneigt ist. Kanalboden und Kanalwand bilden damit eine nach unten - im vorliegenden Fall rechtwinklig - zulaufende V-förmige Lagerfläche einerseits für das noch nicht geschnittene, noch als Strang vorliegende Lebensmittel, und andererseits für die geschnittenen Scheiben des betreffenden Lebensmittels wie beispielsweise eines Brotes.Inside the bread slicer 10 there is a rear guide wall 20 which forms the back of a channel receiving the bread to be sliced. The channel bottom 22 is only in his in Fig. 1 left area shown. In which - based on the Fig. 1 - Right area is this channel floor 22, the in Fig. 2 designated by the reference numeral 22.2, from the housing 12th taken out, as will be described later. The entire channel bottom 22 (22.2) is slightly inclined, so that the cut or to be cut food on the one hand on the channel bottom 22 (22.2) and on the other hand on the front channel wall 24 and 24.2 abuts. The angle of inclination 25 is preferably between 5 degrees and 50 degrees and in the present example case is approximately between 5 degrees and 15 degrees. Channel bottom and channel wall are aligned approximately at right angles to each other. This means that the channel wall 24, 24.2 is inclined into the interior of the housing 12 from the front side. Channel bottom and channel wall thus form a downward - in the present case at right angles - tapered V-shaped bearing surface on the one hand for not yet cut, still present as strand food, and on the other hand for the slices of the relevant food such as a bread.

Der Kanalboden 22 und die vordere Kanalwand 24 werden auf der Vorderseite des Gehäuses 12 teilweise von einer Vorderwand 26 begrenzt. Auf der - bezogen zur Fig. 1 - rechten Hälfte dieses Gehäuses 12 ist diese Vorderwand nicht vorhanden. Dieser rechte Bereich der Vorderwand setzt sich zusammen aus einer rechten oberen Vorderwand 26.2 und einer rechten unteren Vorderwand 26.3 (Fig. 2).The channel bottom 22 and the front channel wall 24 are partially bounded on the front side of the housing 12 by a front wall 26. On the - related to Fig. 1 - Right half of this housing 12, this front wall is not present. This right area of the front wall is composed of a right upper front wall 26.2 and a right lower front wall 26.3 (FIG. Fig. 2 ).

Die rechte obere Vorderwand 26.2 besitzt eine abgeknickte Form und schließt bündig an der ebenfalls abgeknickten Kontur der linken Vorderwand 26 an. An dem oberen Rand 28 der rechten oberen Vorderwand 26.2 schließt sich nach hinten, in das Gehäuse 12 hinein, die bereits erwähnte Kanalwand 24.2 mit dem daran einteilig angeformten Kanalboden 22.2 an. Der Kanalboden 22.2 fluchtet im in die Öffnung 30 eingesetzten Zustand dieser rechten oberen Vorderwand 26.2 mit dem Kanalboden 22. Ebenso fluchtet die Kanalwand 24.2 der rechten oberen Vorderwand 26.2 mit der vorderen Kanalwand 24. Im eingesetzten Zustand liegen der Kanalboden 22.2 und die Kanalwand 24.2 in einer vergleichbaren V-förmig geformten Abstützung 32, die von vorne nach hinten quer durch das Gehäuse 12 hindurch verläuft. Zwischen der Abstützung 32 und dem (linken) Kanalboden 22 ist ein Schlitz 33 für das freie Bewegen eines Kreismessers 66 ausgebildet.The upper right front wall 26.2 has a bent shape and is flush with the also bent contour of the left front wall 26 at. At the upper edge 28 of the upper right front wall 26.2 is closed to the rear, in the housing 12, the already mentioned channel wall 24.2 with the integrally formed thereon channel bottom 22.2. The channel bottom 22.2 is aligned in the inserted state in the opening 30 of this upper right front wall 26.2 with the channel bottom 22. Likewise, the channel wall 24.2 of the right upper front wall 26.2 is aligned with the front channel wall 24. In the inserted state of the channel bottom 22.2 and the channel wall 24.2 lie in one comparable V-shaped support 32 which extends transversely through the housing 12 from front to back. Between the support 32 and the (left) channel bottom 22, a slot 33 for the free movement of a circular blade 66 is formed.

Die rechte obere Vorderwand 26.2 liegt im eingesetzten Zustand das Gehäuse 12 unten an einem Querriegel 34 an. Dieser Querriegel 34 ist zwischen der linken Vorderwand 26 und der rechten Seitenwand 36 des Gehäuses 12 vorhanden. Der Querriegel 34 besitzt einen Anschlag 38, an dem die eingesetzte rechte obere Vorderwand 26.2 mittels eines Drehgriffes 40 in ihrem eingesetzten Zustand verriegelt werden kann.The upper right front wall 26.2 is in the inserted state, the housing 12 at the bottom of a cross bar 34 at. This cross bar 34 is present between the left front wall 26 and the right side wall 36 of the housing 12. Of the Cross bar 34 has a stop 38 on which the inserted upper right front wall 26.2 can be locked by means of a rotary handle 40 in its inserted state.

Unterhalb des Querriegels 34 kann die auf der Vorderseite noch vorhandene Öffnung des Gehäuses 12 durch die rechte untere Vorderwand 26.3 verschlossen werden. Diese rechte untere Vorderwand 26.3 bildet die vordere Seite eines Auffangbehälters 42, in dem die beim Zerschneiden des Lebensmittels anfallenden Krümel aufgefangen werden. Der Auffangbehälter 42 besitzt eine linke und rechte Seitenwand 44, 46 sowie eine hintere Seitenwand 48. Diese Seitenwände rahmen zusammen mit der rechten unteren Vorderwand 26.3 einen Boden 50 ein. Die Seitenwände 44, 46, 48 sind im vorliegenden Beispielsfall niedriger als die rechte untere Vorderwand 26.3. Die rechte Seitenwand 46 schließt von innen bündig an der rechten Seitenwand 36 des Gehäuses 12 an. Die linke Seitenwand 44 schließt seitlich an einer Mittelwand 52 an, die die motorischen und elektrischen Antriebs- und Steuerungseinrichtungen, die hinter der linken Vorderwand 26 vorhanden sind, seitlich begrenzt. Mit seinem obenauf, parallel zur Aufstandsfläche der Doppelrollen 14 ausgerichteten Boden 50 liegt der Krümel-Auffangbehälter 42 im eingesetzten Zustand auf dem Boden 58 des Gehäuses 12 auf.Below the cross bar 34, the still existing on the front opening of the housing 12 can be closed by the lower right front wall 26.3. This right lower front wall 26.3 forms the front side of a collecting container 42, in which the crumbs obtained when cutting the food are collected. The collecting container 42 has a left and right side wall 44, 46 and a rear side wall 48. These side walls frame together with the right lower front wall 26.3 a bottom 50 a. The side walls 44, 46, 48 are lower in the present example than the right lower front wall 26.3. The right side wall 46 connects flush with the right side wall 36 of the housing 12 from the inside. The left sidewall 44 adjoins the side of a center wall 52 which laterally defines the motor and electrical drive and control means provided behind the left front wall 26. With his on top, parallel to the footprint of the double rollers 14 aligned bottom 50 of the crumb collection container 42 is in the inserted state on the bottom 58 of the housing 12.

Oberhalb der linken Seitenwand 44 und der rechten Seitenwand 46 des Auffangbehälters 42 ist jeweils ein Abweisblech 54 (Fig. 1) beziehungsweise 56 (Fig. 2) vorhanden, die sicherstellen, dass beim Schneiden entstandene Krümel sicher in den Auffangbehälter 42 hineinfallen.Above the left side wall 44 and the right side wall 46 of the collecting container 42 is in each case a deflecting plate 54 (FIG. Fig. 1 ) or 56 ( Fig. 2 ), which ensure that crumbs resulting from cutting fall safely into the collecting container 42.

In Fig. 1 ist gut eine Antriebsscheibe 60 zu erkennen, die mit ihrer zentralen Drehachse 62 die Mittelwand 52 durchstößt. Durch den in der Zeichnung nicht dargestellten motorischen Antrieb kann diese Antriebsscheibe 60 in Rotation versetzt werden. An der Antriebsscheibe 60 ist exzentrisch, um eine Drehachse 64 herum, ein Kreismesser 66 gelagert. Das Kreismesser 66 kann im vorliegenden Beispielsfall im Gegenuhrzeigersinn 68 rotierbar angetrieben werden. Zusätzlich kann auch die Antriebsscheibe 60 ebenfalls im Gegenuhrzeigersinn 70 gedreht werden. Durch diese doppelte Rotation wandert das Kreismesser 66 wie ein Satellit um die Drehachse 62 der Antriebsscheibe 60 herum. Das Kreismesser 66 wandert bei seiner Bewegung durch den neben der Abstützung 32 vorhandenen Schlitz 84 hindurch. Das im Bereich des Schlitzes 84 vorhandene strangförmige Lebensmittel wie beispielsweise ein Brot, wird an dieser Stelle dann zertrennt. Bezogen auf die Fig. 1 entsteht dann links von diesem Schlitz 84 eine Scheibe wie beispielsweise eine Brotscheibe. Rechts von dem Schlitz 84 ist der Lebensmittel-Strang wie beispielsweise das Brot noch als Strang vorhanden. Die Antriebsscheibe 60 bewegt sich bei den Rotationen nicht durch den Schlitz 84 hindurch; sie ist ausreichend weit unterhalb dieses Schlitzes 84 vorhanden.In Fig. 1 is good to recognize a drive pulley 60, which pierces the central wall 52 with its central axis of rotation 62. By the motor drive, not shown in the drawing, this drive pulley 60 can be set in rotation. On the drive pulley 60 is mounted eccentrically, about a rotation axis 64 around, a circular blade 66. The circular blade 66 can be rotatably driven counterclockwise 68 in the present example case. In addition, the drive pulley 60 can also be rotated counterclockwise 70. As a result of this double rotation, the circular blade 66 moves around the axis of rotation 62 of the drive pulley 60 like a satellite. The circular blade 66 travels through the slot 84 adjacent to the support 32 as it moves. The existing in the region of the slot 84 strand-shaped food such as bread, is then cut at this point. Related to the Fig. 1 then arises to the left of this slot 84 a disc such as a slice of bread. To the right of the slot 84, the food strand such as the bread is still present as a strand. The drive pulley 60 does not move through the slot 84 during the rotations; it is sufficiently far below this slot 84 available.

Im Bereich des Kanalbodens 22 ist eine Abstützplatte 90 vorhanden. Diese kann über einen motorischen Antrieb längs einer schienenartigen Führung 120 (Fig. 3), die durch eine haubenartige Abdeckung 88 geschützt ist, hin und her (Doppelpfeil 92) bewegt werden. Die Abstützplatte 90 wird so bewegt, dass die eine oder die mehreren geschnittenen Scheiben an ihr nach dem Abschneiden von dem Lebensmittel-Strang abstützend anliegen und nicht auf den Kanalboden 22 umfallen können. Entsprechend des Schneidvorganges wird diese Abstützplatte 90 sich dabei insbesondere taktweise nach - Fig. 1 - links bewegen.In the region of the channel bottom 22, a support plate 90 is present. This can be driven by a motor drive along a rail-like guide 120 (FIG. Fig. 3 ) protected by a hood-like cover 88, are moved back and forth (double arrow 92). The support plate 90 is moved so that the one or more cut slices rest against it after cutting from the food strand and can not fall over the channel bottom 22. According to the cutting process, this support plate 90 is thereby in particular cyclically after - Fig. 1 - move left.

Zum Zerschneiden wird der Lebensmittel-Strang, beispielsweise ein Brot, durch einen Transportschieber 94 in Richtung auf den Schlitz 84 geschoben. Dazu besitzt der Transportschieber 94 mehrere nebeneinander liegende Krallen 96, die beim Schneidvorgang von oben in das Ende des Lebensmittel-Stranges ausreichend fest hineinstechen. Im vorliegenden Fall ist vorgesehen, dass der Transportschieber 94, der sich in Fig. 1 und 2 in seiner rückwärtigen Parkstellung befindet, jeweils bei einem Schneidvorgang taktweise in Richtung dieser Parkstellung ein kleines Stück weit zurückbewegen lässt beziehungsweise dass er zurückbewegt wird und dass er dabei den Lebensmittel-Strang nach - in Fig. 1,2 - rechts ein Stück weit mitnimmt. Dadurch ist die flächige Druckkraft, mit der der Strang an dem Kreismesser 66 flächig anliegt, nach dem Zerschneiden geringer, als es ohne dieses Zurückbewegen der Fall wäre. Um die Druckkraft an dem Kreismesser 66 zu verringern, kann das Zurückbewegen sehr gering sein. Die Gefahr, dass das Lebensmittel sich an der in Fig. 1 sichtbaren Seite des Kreismessers 66 anlegt und dort anhaftet, kann somit ganz wesentlich verringert werden.For cutting, the food strand, for example a bread, is pushed by a transport slider 94 in the direction of the slot 84. For this purpose, the transport slider 94 has a plurality of adjacent claws 96, which penetrate sufficiently sufficiently in the cutting process from above into the end of the food strand. In the present case it is provided that the transport slide 94, located in Fig. 1 and 2 is located in its rear parking position, each time in a cutting operation in the direction of this parking position moves back a little way or that he is moved back and that he doing the food strand after - in Fig. 1 . 2 - takes a bit to the right. As a result, the two-dimensional compressive force with which the strand rests flat against the circular blade 66, after cutting, is less than would be the case without this backward movement. In order to reduce the pressure force on the circular blade 66, the return movement can be very small. The danger that the food will adhere to the in Fig. 1 visible side of the circular blade 66 creates and adheres there, can thus be significantly reduced.

Nach einer in der Zeichnung nicht näher dargestellten Art und Weise kann das Kreismesser 66 in Vibration versetzt werden. Auch dadurch kann ein Anhaften des Lebensmittels sowohl an der dem Transportschieber 94 zugewandten Seite als auch der der Abstützplatte 90 zugewandten Seite verhindert werden.After a manner not shown in the drawing, the circular blade 66 can be vibrated. Also, thereby adhering of the food can be prevented on both the transport slider 94 side facing as well as the support plate 90 side facing.

Es hat sich herausgestellt, dass das Anhaften des Lebensmittels an der der Abstützplatte 90 zugewandten Seite des Kreismessers 66 wirkungsvoll auch dadurch vermieden werden kann, dass nicht nur das Kreismesser 66, sondern insbesondere auch der Kanalboden 22 und die vordere Kanalwand 24 in Vibration versetzt werden.It has been found that the adhesion of the food to the support plate 90 facing side of the circular blade 66 can be effectively avoided by not only the circular blade 66, but in particular the channel bottom 22 and the front channel wall 24 are vibrated.

Dieser Effekt des nicht Anhaftens des Lebensmittels an dem Kreismesser wird ganz entscheidend durch die geneigte Ausrichtung des Zuführkanals verstärkt. Das Vibrieren der Lagerfläche für geschnittene Scheiben setzt vorzugsweise erst nach einer vorbestimmbaren Anzahl von geschnittenen Scheiben ein. Es hat sich herausgestellt, dass zumindest beim Schneiden der ersten zwei Scheiben diese Lagerflächen nicht vibrieren sollen.This effect of non-adherence of the food to the circular knife is greatly enhanced by the inclined orientation of the feed channel. The vibrating of the sliced bearing surface preferably starts after a predeterminable number of cut slices. It has been found that at least when cutting the first two discs, these bearing surfaces should not vibrate.

Durch das Vibrieren der Lagerfläche für die geschnittenen Scheiben ist es möglich, diese Lagerfläche auch horizontal oder sogar leicht ansteigend, gleichsam bergauf, anzuordnen. Nach wie vor kann dabei die Neigung dieser Lagerfläche die Gleiche sein wie die Neigung der Lagerfläche von der Zuführeinrichtung.By vibrating the bearing surface for the cut slices, it is possible to arrange this storage area also horizontally or even slightly rising, as it were uphill. As before, the inclination of this bearing surface may be the same as the inclination of the bearing surface of the feeder.

In Fig. 3 sind die Antriebseinrichtungen und Führungseinrichtungen dargestellt, mit denen ein Lebensmittel beziehungsweise ein Brot und dessen geschnittene Scheiben in einer erfindungsgemäßen Scheibenschneidmaschine transportiert werden. Die in Fig. 3 dargestellte Scheibenschneidmaschine 10.3 entspricht im Wesentlichen der vorstehend beschriebenen Scheibenschneidmaschine 10. Insoweit wird auf die vorstehenden Ausführungen ausdrücklich hingewiesen.In Fig. 3 the drive means and guide means are shown, with which a food or a bread and its cut slices are transported in a disc cutting machine according to the invention. In the Fig. 3 illustrated slicing machine 10.3 substantially corresponds to the disc cutting machine 10 described above. In this regard, the above statements expressly.

Der Transportschieber 94 der Scheibenschneidmaschine 10.3 ist über eine Tragplatte 102, mit der er fest verbunden ist, an einem Antriebsband 104 befestigt. An der - bezogen auf die Fig. 3 - Unterseite der Tragplatte 102 sind in der Zeichnung nicht näher dargestellte Führungsrollen 106, 108 drehbar gelagert, mittels derer sie längs einer schienenartigen Führung 110 hin und her verfahrbar ist. Die Führung 110 ist parallel zur Förderrichtung 112 und damit auch zur Gegen-Förderrichtung 114 hinter der rückwärtigen Führungswand 20 vorhanden. Im - bezogen auf die Fig. 3 - linken Bereich der Scheibenschneidmaschine 10.3 ist eine weitere schienenartige Führung 120 vorhanden, die parallel zur Führung 110 ausgerichtet ist und seitlich versetzt zu der Führung 110 vorhanden ist. Im rechten Bereich der Scheibenschneidmaschine 10.3, d.h. in dem Bereich, wo das zu zerschneidende Lebensmittel, wie im vorliegenden Fall das zu zerschneidende Brot, noch ungeschnitten vorhanden ist, überlappen sich die beiden Führungen 110,120 in einem Bereich 122, um die Abstützplatte 90 möglichst dicht an die durch das Kreismesser 66 definierten Schnittebene von - Fig. 3 - links her heranführen zu können. In der in Fig. 3 dargestellten Situation kann die Abstützplatte 90 aus ihrer strichpunktiert dargestellten Lage noch ein Stück weit in Gegen-Förderrichtung 114 an das Kreismesser 66 herangeschoben werden.The transport slide 94 of the disc cutting machine 10.3 is attached to a drive belt 104 via a support plate 102 with which it is firmly connected. At the - related to the Fig. 3 - Bottom of the support plate 102 are not shown in the drawing guide rollers 106, 108 rotatably supported, by means of which it is along a rail-like guide 110 movable back and forth. The guide 110 is present parallel to the conveying direction 112 and thus also to the counter-conveying direction 114 behind the rear guide wall 20. In relation to the Fig. 3 - Left portion of the slicing machine 10.3, a further rail-like guide 120 is present, which is aligned parallel to the guide 110 and laterally offset from the guide 110 is present. In the right area of the slicing machine 10.3, ie in the area where the food to be cut, as in the present case, the to be cut Bread, still uncut is present, overlap the two guides 110,120 in an area 122 to the support plate 90 as close as possible to the section plane defined by the circular blade 66 of -. Fig. 3 - to be able to introduce you to the left. In the in Fig. 3 shown situation, the support plate 90 can be moved from its position shown in phantom a while in the counter-conveying direction 114 to the circular blade 66.

Das Antriebsband 104 läuft mit einem kanalseitigen Bandabschnitt 104.2 parallel zur Förderrichtung 112 beziehungsweise Gegen-Förderrichtung 114. Am Ende dieses Bandabschnittes 104.2 läuft das Antriebsband 104 um zwei Umlenkrollen 130,132 herum. Das Band 104 ist ferner um eine Spannrolle 134 und um eine motorisch angetriebene weitere Umlenkrolle 136 endlos herumgeführt.The drive belt 104 runs with a channel-side belt section 104.2 parallel to the conveying direction 112 or counter-conveying direction 114. At the end of this belt section 104.2, the drive belt 104 runs around two deflection rollers 130,132. The belt 104 is further guided around a tensioning roller 134 and around a motor-driven further deflection roller 136 endlessly.

Die Tragplatte 102 des Transportschiebers 94 ist nah am Bereich der rechten Umlenkrolle 132 fest an dem Bandabschnitt 104.2 angebracht. Durch motorisches Antreiben der Umlenkrolle 136 kann nun durch entsprechendes Verfahren des Antriebsbandes 104 und damit auch des Bandabschnittes 104.2 der Transportschieber 94 aus seiner in Fig. 3 gezeigten Parkstellung ein vor ihm liegendes Brot in Förderrichtung 112 bewegen. Das Brot kann dann durch das Kreismesser 66 in Scheiben geschnitten werden, so wie es vorstehend bereits beschrieben ist. Die Endstellung des Transportschiebers 94 ist strichpunktiert mit dem Bezugszeichen 94.2 dargestellt. Zwischen diesen Stellungen 94, 94.2 wird das Antriebsband 104 hin und her bewegt, so wie das bereits vorstehend beschrieben ist.The support plate 102 of the transport slide 94 is mounted close to the region of the right deflection roller 132 fixed to the belt section 104.2. By motor driving the guide roller 136 can now by appropriate process of the drive belt 104 and thus also the belt section 104.2 of the transport slide 94 from his in Fig. 3 shown park position in front of him lying bread in the conveying direction 112 move. The bread may then be sliced by the circular knife 66, as previously described. The end position of the transport slide 94 is shown in phantom by the reference numeral 94.2. Between these positions 94, 94.2, the drive belt 104 is moved back and forth, as already described above.

Die Abstützplatte 90 ist fest an einer Tragplatte 140 befestigt. Diese Tragplatte 140 ist ihrerseits fest mit einem Mitnehmer 142 verbunden. Ein an dem Mitnehmer 142 fest angebrachter Schlitten 154 besitzt in der Zeichnung nicht näher dargestellte Führungsrollen, mit denen er längs der schienenartigen Führung 120 in Förderrichtung 112 und in Gegen-Förderrichtung 114 hin und her verstellbar geführt ist.The support plate 90 is fixedly attached to a support plate 140. This support plate 140 is in turn firmly connected to a driver 142. A fixed to the driver 142 carriage 154 has not shown in the drawing guide rollers, with which it is guided along the rail-like guide 120 in the conveying direction 112 and in the counter-conveying direction 114 back and forth adjustably.

Der Mitnehmer 142 besitzt eine elektromagnetische Klaue 144, zwischen deren beiden Klauen der Bandabschnitt 104.2 des Antriebsbandes 104 frei geführt ist. Durch elektromagnetische Betätigung kann die Klaue 144 geschlossen werden. Dabei klemmt sie das Antriebsband 104 fest zwischen sich ein. Auf diese Weise kann der Mitnehmer 142 und damit letztendlich die Abstützplatte 90 fest an dem Antriebsband 104 befestigt werden. Beim motorischen Antrieb des Antriebsbandes 104 kann sich also die Abstützplatte 90 gleichförmig mit dem Transportschieber 94 in Förderrichtung 112 mit bewegen. Beim Antreiben des Antriebsbandes 104 in Gegen-Förderrichtung 114 kann der Mitnehmer 142 und damit die elektromagnetische Klaue 144 geöffnet werden, so dass der Transportschieber 94 motorisch in seine in Fig. 3 dargestellte rechte Parkstellung zurück geschoben werden kann, ohne dass dabei auch die Abstützplatte 90 mit in Gegen-Förderrichtung 114 bewegt wird. Beim Bewegen des Antriebsbandes 104 und damit des Transportschiebers 94 während des eigentlichen Scheibenschneidvorganges jeweils ein kleines Stück weit in Gegen-Förderrichtung 114 kann die Klaue 144 geschlossen bleiben.The driver 142 has an electromagnetic claw 144, between the two claws of the belt portion 104.2 of the drive belt 104 is guided freely. By electromagnetic actuation, the claw 144 can be closed. It clamps the drive belt 104 firmly between them. In this way, the driver 142 and thus ultimately the support plate 90 can be firmly attached to the drive belt 104. For motor drive of the drive belt 104 so the support plate 90 can move uniformly with the transport slide 94 in the conveying direction 112 with. When driving the drive belt 104 in the counter-conveying direction 114, the driver 142 and thus the electromagnetic claw 144 can be opened, so that the transport slide 94 motor in his in Fig. 3 shown right parking position can be pushed back without causing the support plate 90 is moved in the counter-conveying direction 114. When moving the drive belt 104 and thus the transport slide 94 during the actual slicing process each a small distance in the counter-conveying direction 114, the claw 144 may remain closed.

Es ist im vorliegenden Beispielsfall vorgesehen, die Abstützplatte 90 nach dem vollständigen Zerschneiden eines Brotes manuell in Gegen-Förderrichtung 114 zurück zu bewegen, und zwar erst dann, wenn die geschnittenen Brotscheiben aus der Scheibenschneidmaschine herausgenommen worden sind.It is provided in the present example case to manually move the support plate 90 in the counter-conveying direction 114 after the complete cutting of a bread, and that only when the sliced bread slices have been removed from the slicer.

Beim Beginn des Zerschneidens eines Brotes oder eines sonstigen Lebensmittels muss sichergestellt sein, dass die Abstützplatte 90 sich im vorgegebenen, dichten Abstand zum Kreismesser 66 befindet, also nach rechts verschoben worden ist und sich nicht in ihrer in Fig. 3 durchgezogen gezeichneten linken Stellung befindet. Wenn beim Starten des Antriebsbandes 104 die Klaue 144 geschlossen wird und die Abstützplatte 90 sich infolgedessen synchron mit dem Transportschieber 94 in Förderrichtung 112 bewegt, darf sich die Abstützplatte 90 nicht in ihrer in Fig. 3 gezeigten linken Endstellung befinden. Durch einen Endschalter, der sich beispielsweise im Bereich zwischen der Abstützplatte 90 und der linken Seitenwand 150 befinden kann, wird sichergestellt, dass beim Anstoßen der Abstützplatte 90 oder auch der Tragplatte 140 oder eines sonstigen mit der Abstützplatte 90 fest verbundenen Teils an diesem Endschalter, der in der Zeichnung nicht dargestellt ist, der elektromotorische Antrieb der Umlenkrolle 136 gestoppt wird. Vergleichbares kann auch erreicht werden, wenn durch entsprechende Endschalter der - bezogen auf die Fig. 3 - rechte Startbereich der Abstützplatte 90 überwacht wird.At the beginning of cutting a bread or other food must be ensured that the support plate 90 is at a predetermined, close distance to the circular blade 66, that has been moved to the right and not in their in Fig. 3 drawn solid left position. If when starting the drive belt 104, the claw 144 is closed and the support plate 90 moves as a result synchronously with the transport slide 94 in the conveying direction 112, the support plate 90 is not in their in Fig. 3 shown left end position. By a limit switch, which may be located for example in the area between the support plate 90 and the left side wall 150, it is ensured that when abutment of the support plate 90 or the support plate 140 or other firmly connected to the support plate 90 part of this limit switch, the not shown in the drawing, the electromotive drive of the guide roller 136 is stopped. Comparable can also be achieved if by appropriate limit - the - related to the Fig. 3 - Right start area of the support plate 90 is monitored.
