Definitions
- the disc support is manually moved back to the starting position after completion of the cutting process and removal of the cut disc package, which is usually done in practice by a pushing back of the slidingly mounted on a guide rod disc support.
- Such a cutting machine in which, in order to facilitate the work for the operator on the one hand, the storage area of the receiving area in the course of opening a cover to the operator is pivotable to facilitate the packaging of the disc pack in foil bag.
- a further relief for the operator is that with the opening of the cover to the other also a pivoting of the guide rails of the disk support is coupled, whereby the latter is removed both from the feed cross section for the disk package as well as in an elevated position, out of the them due to gravity due to sliding on the guide rods down automatically moves back to the starting position. After closing the cover, therefore, the machine is ready to cut open a next loaf of bread without restriction.
- a coupling of the disk return as described above with the operation of the cover is particularly advantageous if such machines are to be operated by customers.
- This concept is increasingly practiced in recent times for reasons of personnel savings both in bakery shops, especially those with a self-service by the customer, or in stores of food discounters, in which increasingly also bread makers are set up and the There, baked bread can be cut open by the customer using the bread slicing machines described above, if desired.
- the invention has for its object to provide a bread slicer with a return of the disc support from its final position to the starting position, which is easy to manufacture, is characterized by their robustness and variable in terms of both the starting position of the disc support and on a Return of the disc support triggering restoring force is.
- the underlying object is achieved in that the disc support is moved back by means of the weight of a counterweight device from the end position to the starting position, wherein a counterweight of the counterweight device is disposed outside of the receiving area and within a machine housing.
- the bread slicer according to the invention thus dispenses, on the one hand, with a mechanical coupling between any safety devices or operating elements and the disk support, which simplifies the construction of the machine.
- a separate arrangement of a counterweight device on the other hand allows a targeted adjustment of the force acting on the disc support force.
- the restoring device for the disc support can thus be constructed as separate from selbiger present assembly, executed and for the sole determination of the return movement of the disc support in the start position - for example, with respect to the restoring force - optimized. In this way it is much easier to achieve the robustness demanded by customers in the field of self-service. Furthermore, the probability of incorrect operation by the customer is almost completely eliminated.
- Retraction of the disc support from the end position to the start position is ultimately accomplished by "charging" the resetting device or counterweight device with potential energy supplied by the advancing device during transfer of the counterweight device from the start position to the end position.
- a separate powered by external energy drive for the counterweight device is not required.
- the disc support is rotatably mounted about a preferably perpendicular to the storage surface of the receiving area aligned axis of rotation and rotates in its movement from the start position to the end position and vice versa about this axis of rotation.
- a rotational movement of the disc support allows a very simple storage, which is also characterized by its low friction.
- the risk of contamination caused by the cutting process crumbs or flour dust is not given, so that such storage requires no cleaning and thus virtually maintenance-free.
- the two arms arranged on opposite sides of the axis of rotation make it possible to arrange the restoring device outside the receiving area in order to exclude obstacles when advancing the disk package.
- the disc support When the axis of rotation of the disc support is at an angle to the vertical and the counterweight device is a counterweight rigidly coupled to the return arm, the disc support will always seek to rotate under the weight of the counterweight so that the counterweight is at the lowest possible position. ie the position with the lowest energy level - occupies. In this way, or by a correspondingly previously effective stop, the starting position of the disc support can be defined.
- a distance of the center of gravity of the counterweight should be adjustable from the axis of rotation.
- a particularly advantageous embodiment is that the surface normal of the footprint of the receiving area is parallel to the axis of rotation of the disc support.
- the axis of rotation, and in particular the physical pivoting joint embodying it can then preferably be arranged in or on a side wall of the receiving area, the support arm then being located in the receiving area, in particular within a receiving shaft, and the return arm with the counterweight device being located inside a behind the receiving shaft Machine housing is located and thus not accessible to the user and is well protected against the ingress of dirt.
- the Supporting element have a aligned in the starting position of the disc support parallel to a knife plane center area, in particular in the critical phase in which the first discs - possibly even a tail with a convex surface - must be supported.
- the safe interception of the first disc is favored when the support member has a subsequent to the central region, the knife inclined end capture section, since in particular a lateral deflection of the first cut disc in a direction parallel to the knife plane or the central region is prevented.
- the axis of rotation of the disc support should be arranged on the same side of the cutting cross section as the at least one axis of rotation of the cutting device, ie the axis of rotation of a sickle blade or the axis of rotation of a knife rocker of a circular knife with orbital drive. Furthermore, the support element should still have a on the catch portion opposite side of the central region of this subsequent and the knife averse to late support area. This is due to the rotational movement of the support member together with the entire disc support with increasing distance of the support member from the knife level, ie with increasing number of cut discs, effective.
- the transition between the central region and the late support region can - like the transition between the central region and the catching section - be designed in the form of a bend or a rounding.
- a preferably made of a rubber elastic material stop element should be present, which is able to prevent the rotational movement of the counterweight device and consequently also the disc support in a position of a minimum potential energy level.
- the stop element is arranged in a particularly advantageous manner on the return arm and cooperates with a receiving area facing away from a side wall of the receiving area.
- a counterweight device may be embodied, for example, in the form of a cable pull, which is connected at one end to the disk support and at the other end to a counterweight, which is preferably freely suspended.
- FIG. 1 An in FIG. 1 Cutting machine 1 shown in a front view has a box-shaped machine housing 2, which is slidably mounted on a four rotatably mounted about a vertical axis rollers 3 on a floor.
- the cutting machine 1 has a feed region 4, which is of a shaft-shaped design and serves for inserting a loaf of bread to be cut.
- the cutting machine 1 has a receiving area 5 arranged linearly adjacent to the feed area 4, which in a vertical section in FIG FIG. 3 and in a plan view in FIG FIG. 2 is shown enlarged.
- a non-visible cutting device in the form of a known orbital gear in which a circular blade rotating about its own axis is arranged on a knife rocker likewise rotating about a rocker axis.
- An end portion of the knife rocker covers a portion of the circular blade and is wedge-shaped in cross-section, since this end portion penetrates during the cutting process in the cross section of the loaf and the new disc from this deflects.
- a feed device in a known form with a feed element in the form of a feed plate or feed claw is executed.
- the loaf of bread inserted in the feed region 4 can be advanced progressively onto the knife of the cutting device in operation, depending on the set slice thickness, in order to produce successive slices of bread, which are then approximately in the form of the uncut loaf as slice package in the receiving region 5 accumulate and there in the feed direction (arrow 6) are pushed on.
- the basic structure of the cutting machine 1 described above is well known.
- the receiving area 5 comprises a receiving shaft 7, the bottom of which is formed by a crumb tray 8, which in turn acts with an upwardly facing surface as a storage area for the cut slices or the disk pack formed therefrom.
- a crumb tray 8 which in turn acts with an upwardly facing surface as a storage area for the cut slices or the disk pack formed therefrom.
- Through longitudinal slots 10 crumbs can fall through the crumb tray 8 through and collect in an underlying crumb tray, which must be emptied occasionally.
- a cutting plane of the blade of the cutting device In the plan view according to FIG. 2 is defined by a line 12 a cutting plane of the blade of the cutting device. At a small distance 13 from the cutting plane is an existing sheet metal support member 14 of a disk support 15. This is used to catch and support the cut slices or the successive building up disk package while it is advanced in the receiving area 5 in the feed direction.
- the disc support 15 is rotatably mounted about an axis of rotation 16 which extends within the plane of a side wall 17 of the receiving shaft 7.
- a two-part bracket 18 of the disk support 15 is bolted to the side wall 17. While a package of cut-off disks forms in the receiving region 5, the disk-supported support 15, in particular its support element 14 coming into contact with the first cut-off wheel, makes a circular movement about the axis of rotation 16, illustrated by a FIG. 2 As the axis of rotation 16 extends at a right angle to the shelf 9, a lower edge 20 of the support member 14 always retains the same minimum distance from the shelf 9 during the pivoting movement.
- the disc support 15 has a support arm 21 and a return arm 22 which are arranged on opposite sides of the axis of rotation 16.
- the support arm 21 is connected at its free end to the support member 14, whereas the free end of the return arm 22 is provided with a counterweight means 23 in the form of a barrel-shaped counterweight 24 and a stop member 25 disposed thereon.
- the support arm 21 with the support element 14 is located within the receiving area 5, whereas the return arm 22 with the counterweight device 23 in a space behind the side wall 17, that is covered within the machine housing 2, is located.
- the support element 14 - in particular its front side facing the cutting device - consists of three sections, namely a middle section 27, a catch section 28 and a late support section 29.
- the middle section 27 extending parallel to the knife plane, the support arm 21 closes against the support element 14 at.
- the catching portion 28 connects, which extends at an angle of about 15 ° to 25 ° inclined to the knife plane.
- the central portion 27 extends in the start position parallel to the knife plane, its orientation changes in the course of the rotation of the disk support 15 about the rotation axis 16 continuously.
- the late support portion 29 is inclined at an angle of about 25 ° to 30 ° to the blade plane and directed away from this.
- the "automatic" of the return pivoting of the disc support 15 - after the disc package was removed from the receiving shaft 7 after completion of the cutting process - is due to the inclination of the side wall 17 and thus also the axis of rotation 18 of the disc support 15 with respect to a vertical arrangement.
- the counterweight 24 is always endeavored, in the Figures 1 and 2 assumed starting position in which the support member 14 of the disc support 15 is arranged in the start position and the stop element 25 rests against the back of the side wall 17.
- the amount of counterforce applied to the forming disk pack by the counterweight during the cutting operation can be adjusted by varying the distance of the counterweight 24 from the axis of rotation 16 by displacement.
- the counterweight 24 determines, in particular, the force component exerted during the return, which exerts a restoring torque about the axis of rotation 16 on the disk support 15.

- einer Schneideinrichtung, die ein um mindestens eine Drehachse rotierbares Messer aufweist,
- einem Zuführbereich, in den ein Laib eines zu schneidenden Brots einlegbar ist,
- eine Vorschubeinrichtung, mit der ein in dem Zuführbereich angeordneter zu schneidender Laib so auf die Schneideinrichtung zu vorschiebbar ist, dass sukzessive von einem vorderen Ende des Laibs mit der Schneideinrichtung Scheiben abschneidbar sind,
- einem Aufnahmebereich, in dem die abgeschnittenen Scheiben so aufnehmbar sind, dass sich im Laufe des Abschneidens einer Mehrzahl von Scheiben aus diesen in dem Aufnahmebereich ein Scheibenpaket bildet, das ungefähr die Form des ungeschnittenen Laibs aufweist, wobei die abgeschnittenen Scheiben jeweils mit einer Unterseite auf eine Abstellfläche des Aufnahmebereichs aufstehen und
- einer Scheibenstütze, mit der die erste abgeschnittene Scheibe und das jeweils aus dieser und weiteren nachfolgend abgeschnittenen Scheiben gebildete Scheibenpaket abstützbar ist, wobei die Scheibenstütze von einer Startposition, in der sie in der Nähe der Schneideinrichtung angeordnet ist, in Folge des fortlaufenden Abschneiden des Laibs von dem sich in Vorschubrichtung vorschiebenden Scheibenpaket in eine Endposition bewegbar ist, in der der Laib vollständig aufgeschnitten ist.
- a cutting device which has a knife rotatable about at least one axis of rotation,
- a feed area into which a loaf of bread to be cut can be inserted,
- a feed device, with which a loaf to be cut arranged in the feed region can be advanced toward the cutting device in such a way that slices can be cut successively from a front end of the loaf with the cutting device,
- a receiving region in which the cut-off discs are receivable so that in the course of cutting a plurality of discs of these in the receiving area forms a disc package having approximately the shape of the uncut loaf, the cut discs each with a bottom on a Stand up the storage area of the storage area and
- a disk support with which the first cut-off disk and the disk package formed respectively from this and further subsequently cut-off disks can be supported, the disk support being arranged from a starting position in which it is arranged in the vicinity of the cutting device as a consequence of the continuous cutting of the loaf the advancing in the feed direction disc pack is movable into an end position in which the loaf is completely cut.
Brotschneidemaschinen der vorgenannten Art sind allgemein bekannt und werden häufig in Verkaufslokalen von Bäckereifilialbetrieben aufgestellt und dort von Fachpersonal bedient. Die in den Maschinen vorhandene Scheibenstütze hat die Aufgabe, die Bildung eines geordneten, d.h. geometrisch exakt gebildeten, Scheibenpakets im Aufnahmebereich zu unterstützen. Insbesondere bei der ersten abzuschneidenden Scheibe besteht die große Gefahr, dass diese ohne entsprechende Abstützung auf ihrer dem Messer abgewandten Seite durch die beim Schneiden auftretenden und in Vorschubrichtung sowie senkrecht hierzu wirkenden Querkräfte unkontrolliert weggeschleudert wird. Dies gilt insbesondere bei Broten mit harter Kruste und bei Verwendung von Schneideinrichtungen mit einem Kreismesser, das nach Art eines Planetenrads umlaufend an einer rotatorisch angetriebenen Messerschwinge rotiert. Da meist kreisförmig angeschrägte Abschnitte der Messerschwinge in den Brotlaib eindringen, wird eine nicht unerhebliche Keilwirkung auf die gerade im Entstehen begriffene Scheibe ausgeübt, so dass die Anforderungen an die Scheibenstütze entsprechend hoch sind.Bread slicers of the aforementioned type are well known and are often placed in sales outlets of bakeries and operated there by qualified personnel. The existing in the machines disc support has the task of supporting the formation of an orderly, ie geometrically formed exactly, disc package in the receiving area. Particularly in the case of the first slice to be cut off, there is a great risk that it will be thrown out uncontrollably without appropriate support on its side facing away from the knife by the transverse forces which occur during cutting and in the feed direction and perpendicular thereto. This is especially true for breads with a hard crust and when using cutting devices with a circular blade that rotates circumferentially on a rotatably driven knife rocker in the manner of a planetary gear. Since most circular bevelled portions of the knife rocker penetrate into the loaf, a significant wedge effect is exerted on the just emerging disc, so that the requirements for the disc support are correspondingly high.
Insbesondere bei Bedienung durch Fachpersonal ist es bei den bekannten Maschinen Standard, dass die Scheibenstütze nach Beendigung des Schneidvorgangs und Entnahme des geschnittenen Scheibenpakets manuell in die Startposition zurückbewegt wird, was in der Praxis meist durch ein Zurückschieben der gleitend an einer Führungsstange gelagerten Scheibenstütze erfolgt.In particular, when operated by professionals, it is standard in the known machines that the disc support is manually moved back to the starting position after completion of the cutting process and removal of the cut disc package, which is usually done in practice by a pushing back of the slidingly mounted on a guide rod disc support.
Aus der
Eine wie vorstehend beschriebene Kopplung der Scheibenrückstellung mit der Betätigung der Abdeckhaube ist insbesondere dann vor Vorteil, wenn solche Maschinen von Kunden bedient werden sollen. Dieses Konzept wird in jüngerer Vergangenheit aus Gründen der Personaleinsparung zunehmend praktiziert und zwar sowohl in Bäckereifilialgeschäften, insbesondere solchen mit einer Selbstbedienung durch den Kunden, oder aber auch in Filialen von Lebensmitteldiscountern, in denen zunehmend auch Brotbackautomaten aufgestellt werden und das dort gebackene Brot vom Kunden unter Verwendung der vorstehend beschriebenen Brotschneidemaschinen eigenständig aufgeschnitten werden kann, falls dies gewünscht ist.A coupling of the disk return as described above with the operation of the cover is particularly advantageous if such machines are to be operated by customers. This concept is increasingly practiced in recent times for reasons of personnel savings both in bakery shops, especially those with a self-service by the customer, or in stores of food discounters, in which increasingly also bread makers are set up and the There, baked bread can be cut open by the customer using the bread slicing machines described above, if desired.
Auch wenn sich die Maschine gemäß der
Eine Alternative für eine selbstgängige Rückführung der Scheibenstütze in eine Startposition geht aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Brotschneidemaschine mit einer Rückführung der Scheibenstütze von deren Endposition in die Startposition bereit zu stellen, die sich einfach herstellen lässt, sich durch ihre Robustheit auszeichnet und variabel im Hinblick sowohl auf die Startposition der Scheibenstütze als auch auf eine die Rückführung der Scheibenstütze auslösende Rückstellkraft ist.The invention has for its object to provide a bread slicer with a return of the disc support from its final position to the starting position, which is easy to manufacture, is characterized by their robustness and variable in terms of both the starting position of the disc support and on a Return of the disc support triggering restoring force is.
Ausgehend von einer Brotschneidemaschine der eingangs beschriebenen Art wird die zugrunde liegende Aufgabe dadurch gelöst, dass die Scheibenstütze mittels der Gewichtskraft einer Gegengewichtseinrichtung von der Endposition in die Startposition zurückbewegbar ist, wobei ein Gegengewicht der Gegengewichtseinrichtung außerhalb des Aufnahmebereichs und innerhalb eines Maschinengehäuses angeordnet ist.Based on a bread slicer of the type described above, the underlying object is achieved in that the disc support is moved back by means of the weight of a counterweight device from the end position to the starting position, wherein a counterweight of the counterweight device is disposed outside of the receiving area and within a machine housing.
Die erfindungsgemäße Brotschneidemaschine verzichtet somit einerseits auf eine mechanische Kopplung zwischen etwaigen Sicherheitseinrichtungen oder Bedienelementen und der Scheibenstütze, wodurch der Aufbau der Maschine vereinfacht wird. Neben weiteren Vorteilen wie der Einfachheit und Verschleißarmut einer solchen Vorrichtung, ermöglicht eine separate Anordnung einer Gegengewichtseinrichtung andererseits ein gezieltes Einstellen der auf die Scheibenstütze wirkenden Kraft. Die Rückstelleinrichtung für die Scheibenstütze kann somit als getrennt von selbiger vorliegende Baugruppe konstruiert, ausgeführt und für die alleinige Bestimmung der Rückbewegung der Scheibenstütze in die Startposition - beispielsweise hinsichtlich der Rückstellkraft - optimiert werden. Auf diese Weise lässt sich sehr viel leichter die im Bereich der Selbstbedienung durch Kunden geforderte Robustheit erzielen. Ferner ist die Wahrscheinlichkeit einer Fehlbedienung seitens des Kunden nahezu vollständig ausgeräumt.The bread slicer according to the invention thus dispenses, on the one hand, with a mechanical coupling between any safety devices or operating elements and the disk support, which simplifies the construction of the machine. In addition to other advantages such as the simplicity and low wear of such a device, a separate arrangement of a counterweight device on the other hand allows a targeted adjustment of the force acting on the disc support force. The restoring device for the disc support can thus be constructed as separate from selbiger present assembly, executed and for the sole determination of the return movement of the disc support in the start position - for example, with respect to the restoring force - optimized. In this way it is much easier to achieve the robustness demanded by customers in the field of self-service. Furthermore, the probability of incorrect operation by the customer is almost completely eliminated.
Ein Zurückbewegen der Scheibenstütze von der End- in die Startposition erfolgt letztendlich über eine "Aufladung" der Rückstelleinrichtung beziehungsweise der Gegengewichtseinrichtung mit potentieller Energie, die von der Vorschubeinrichtung während einer Überführung der Gegengewichtseinrichtung von der Start- in die Endposition geliefert wird. Ein separater, mit Fremdenergie betriebener Antrieb für die Gegengewichtseinrichtung ist nicht erforderlich.Retraction of the disc support from the end position to the start position is ultimately accomplished by "charging" the resetting device or counterweight device with potential energy supplied by the advancing device during transfer of the counterweight device from the start position to the end position. A separate powered by external energy drive for the counterweight device is not required.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist die Scheibenstütze um eine vorzugsweise senkrecht zu der Abstellfläche des Aufnahmebereichs ausgerichteten Drehachse drehbar gelagert und dreht sich bei ihrer Bewegung von der Startposition in die Endposition und umgekehrt um diese Drehachse. Eine derartige Drehbewegung der Scheibenstütze ermöglicht eine ganz besonders einfache Lagerung, die sich zudem durch ihre Reibungsarmut auszeichnet. Im Gegensatz zu Linearführungen ist insbesondere die Gefahr von Verschmutzungen durch beim Schneidvorgang entstehende Krümel oder durch Mehlstaub nicht gegeben, so dass eine derartige Lagerung keinerlei Reinigung bedarf und somit quasi wartungsfrei ist.According to a particularly advantageous embodiment of the invention, the disc support is rotatably mounted about a preferably perpendicular to the storage surface of the receiving area aligned axis of rotation and rotates in its movement from the start position to the end position and vice versa about this axis of rotation. Such a rotational movement of the disc support allows a very simple storage, which is also characterized by its low friction. In contrast to linear guides in particular the risk of contamination caused by the cutting process crumbs or flour dust is not given, so that such storage requires no cleaning and thus virtually maintenance-free.
Die Erfindung weiter ausgestaltend ist vorgesehen, dass die Scheibenstütze bei drehbarer Lagerung
- einen Stützarm, der sich in dem Aufnahmebereich befindet und an einem der Drehachse abgewandten Ende ein Stützelement aufweist, mit dem die abgeschnittenen Scheiben abstützbar sind, und
- einen Rückstellarm aufweist, der an einem der Drehachse abgewandten Ende mit der Federeinrichtung verbunden ist.
- a support arm, which is located in the receiving area and at a side facing away from the axis of rotation has a support element with which the cut-off discs can be supported, and
- a return arm, which is connected at an end remote from the axis of rotation with the spring means.
Die zwei auf gegenüber liegenden Seiten der Drehachse angeordneten Arme ermöglichen es, die Rückstelleinrichtung außerhalb des Aufnahmebereichs anzuordnen, um Behinderungen beim Vorschieben des Scheibenpakets auszuschließen.The two arms arranged on opposite sides of the axis of rotation make it possible to arrange the restoring device outside the receiving area in order to exclude obstacles when advancing the disk package.
Wenn die Drehachse der Scheibenstütze unter einem Winkel zur Vertikalen verläuft und die Gegengewichteinrichtung ein Gegengewicht ist, das starr mit dem Rückstellarm gekoppelt ist, ist die Scheibenstütze stets bestrebt, sich unter Einwirkung der Gewichtskraft des Gegengewichts so zu drehen, dass das Gegengewicht die tiefstmögliche Position - also diejenige Position mit dem geringsten Energieniveau - einnimmt. Auf diese Weise, oder durch einen entsprechend vorher wirksamen Anschlag, kann die Startposition der Scheibenstütze definiert werden. Um Justierungen bei der auf das Scheibenpaket im Zuge seines Vorschiebens ausgeübten Gegenkraft vornehmen zu können, sollte ein Abstand des Schwerpunkts des Gegengewichts von der Drehachse einstellbar sein.When the axis of rotation of the disc support is at an angle to the vertical and the counterweight device is a counterweight rigidly coupled to the return arm, the disc support will always seek to rotate under the weight of the counterweight so that the counterweight is at the lowest possible position. ie the position with the lowest energy level - occupies. In this way, or by a correspondingly previously effective stop, the starting position of the disc support can be defined. In order to make adjustments in the force exerted on the disk package in the course of its advancing counterforce, a distance of the center of gravity of the counterweight should be adjustable from the axis of rotation.
Eine besonders günstige Ausgestaltung besteht darin, dass die Flächennormale der Aufstandsfläche des Aufnahmebereichs parallel zu der Drehachse der Scheibenstütze verläuft. Die Drehachse und insbesondere das diese verkörpernde physische Drehgelenk kann dann vorzugsweise in oder an einer Seitenwand des Aufnahmebereichs angeordnet werden, wobei der Stützarm sich dann in dem Aufnahmebereich, insbesondere innerhalb eines Aufnahmeschachts, und der Rückstellarm mit der Gegengewichtseinrichtung sich im Inneren eines hinter dem Aufnahmeschacht befindlichen Maschinengehäuses befindet und damit für den Benutzer nicht zugänglich ist und auch vor dem Eindringen von Verschmutzungen gut geschützt ist.A particularly advantageous embodiment is that the surface normal of the footprint of the receiving area is parallel to the axis of rotation of the disc support. The axis of rotation, and in particular the physical pivoting joint embodying it, can then preferably be arranged in or on a side wall of the receiving area, the support arm then being located in the receiving area, in particular within a receiving shaft, and the return arm with the counterweight device being located inside a behind the receiving shaft Machine housing is located and thus not accessible to the user and is well protected against the ingress of dirt.
Um trotz der Drehbewegung der Scheibenstütze während des gesamten Aufschneidevorgangs eines Brotlaibs - beginnend mit der ersten bis hin zur letzten Scheibe - gute Abstützergebnisse und insbesondere eine geometriegenaue Scheibenanordnung zu erreichen, kann das Stützelement einen in der Startposition der Scheibenstütze parallel zu einer Messerebene ausgerichteten Mittelbereich besitzen, der insbesondere in der kritischen Phase, in der die ersten Scheiben - möglicherweise noch ein Endstück mit konvexer Oberfläche - abgestützt werden müssen. Insbesondere das sichere Abfangen der ersten Scheibe wird begünstigt, wenn das Stützelement einen sich an den Mittelbereich anschließenden, dem Messer zugeneigten Fangabschnitt aufweist, da hiermit insbesondere ein seitliches Ausweichen der ersten abgeschnittenen Scheibe in eine Richtung parallel zu der Messerebene bzw. dem Mittelbereich verhindert wird. Die Drehachse der Scheibenstütze sollte auf derselben Seite des Schneidquerschnitts angeordnet sein, wie die mindestens eine Drehachse der Schneideinrichtung, d.h. die Drehachse eines Sichelmessers oder die Drehachse einer Messerschwinge eines Kreismessers mit Orbitalantrieb. Ferner sollte das Stützelement noch einen sich an der dem Fangabschnitt gegenüber liegenden Seite des Mittelbereichs an diesen anschließenden und dem Messer abgeneigten Spätstützbereich aufweisen. Dieser wird infolge der Drehbewegung des Stützelements zusammen mit der gesamten Scheibenstütze mit zunehmendem Abstand des Stützelements von der Messerebene, d.h. mit zunehmender Anzahl der abgeschnittenen Scheiben, wirksam. Der Übergang zwischen dem Mittelbereich und dem Spätstützbereich kann - ebenso wie der Übergang zwischen dem Mittelbereich und dem Fangabschnitt - in Form eines Knicks oder einer Rundung ausgestaltet sein.In spite of the rotational movement of the disc support during the entire slicing process of a loaf of bread - starting with the first to the last slice - to achieve good support results and in particular a geometriegenaue disc arrangement, the Supporting element have a aligned in the starting position of the disc support parallel to a knife plane center area, in particular in the critical phase in which the first discs - possibly even a tail with a convex surface - must be supported. In particular, the safe interception of the first disc is favored when the support member has a subsequent to the central region, the knife inclined end capture section, since in particular a lateral deflection of the first cut disc in a direction parallel to the knife plane or the central region is prevented. The axis of rotation of the disc support should be arranged on the same side of the cutting cross section as the at least one axis of rotation of the cutting device, ie the axis of rotation of a sickle blade or the axis of rotation of a knife rocker of a circular knife with orbital drive. Furthermore, the support element should still have a on the catch portion opposite side of the central region of this subsequent and the knife averse to late support area. This is due to the rotational movement of the support member together with the entire disc support with increasing distance of the support member from the knife level, ie with increasing number of cut discs, effective. The transition between the central region and the late support region can - like the transition between the central region and the catching section - be designed in the form of a bend or a rounding.
Um die Startposition der Scheibenstütze genau definieren zu können, sollte ein vorzugsweise aus einem gummielastischem Material bestehendes Anschlagelement vorhanden sein, das die Drehbewegung der Gegengewichtseinrichtung und folglich auch der Scheibenstütze in eine Position eines minimalen potentialen Energieniveaus zu unterbinden vermag. Das Anschlagelement wird in besonders vorteilhafter Weise an dem Rückstellarm angeordnet und wirkt mit einer dem Aufnahmebereich abgewandten Seite einer Seitenwand des Aufnahmebereichs zusammen.In order to accurately define the starting position of the disc support, a preferably made of a rubber elastic material stop element should be present, which is able to prevent the rotational movement of the counterweight device and consequently also the disc support in a position of a minimum potential energy level. The stop element is arranged in a particularly advantageous manner on the return arm and cooperates with a receiving area facing away from a side wall of the receiving area.
Wird eine lineare Bewegung des Stützelements bevorzugt, so kann eine Gegengewichteinrichtung beispielsweise in Form eines Seilzugs ausgeführt sein, der mit einem Ende an der Scheibenstütze und mit dem anderen Ende mit einem Gegengewicht, das vorzugsweise frei hängend angeordnet ist, verbunden ist.If a linear movement of the support member is preferred, then a counterweight device may be embodied, for example, in the form of a cable pull, which is connected at one end to the disk support and at the other end to a counterweight, which is preferably freely suspended.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels einer Brotschneidemaschine, die in der Zeichnung dargestellt ist, näher erläutert.The invention will be explained in more detail with reference to an embodiment of a bread slicing machine, which is shown in the drawing.

Im Inneren des Maschinengehäuses 2 befindet sich eine nicht sichtbare Schneideinrichtung in Form eines bekannten Orbitalgetriebes, bei dem ein um seine eigene Achse rotierendes Kreismesser an einer gleichfalls um eine Schwingenachse rotierenden Messerschwinge angeordnet ist. Ein Endbereich der Messerschwinge überdeckt einen Teil des Kreismessers und ist im Querschnitt keilförmig ausgebildet, da dieser Endbereich beim Abschneidevorgang in den Querschnitt des Brotlaibs eindringt und die neu entstehende Scheibe von diesem ablenkt.Inside the
Ebenfalls nicht sichtbar im Inneren des Maschinengehäuses 2 befindet sich eine Vorschubeinrichtung, die in bekannter Form mit einem Vorschubelement in Form einer Vorschubplatte oder Vorschubkralle ausgeführt ist. Mittels der Vorschubeinrichtung lässt sich der in den Zuführbereich 4 eingelegte Brotlaib - je nach eingestellter Scheibendicke - schrittweise auf das Messer der in Betrieb befindlichen Schneideinrichtung vorschieben, um sukzessive Brotscheiben zu erzeugen, die sich sodann ungefähr in der Form des ungeschnittenen Laibs als Scheibenpaket in dem Aufnahmebereich 5 ansammeln und dort in Vorschubrichtung (Pfeil 6) weitergeschoben werden. Der vorstehend beschriebene grundsätzliche Aufbau der Schneidmaschine 1 ist allgemein bekannt.Also not visible in the interior of the
