Technisches GebietTechnical area

Die Erfindung betrifft eine Schneidemaschine für Lebensmittel wie Wurst, Käse oder dergleichen, mit einem Gehäuse, einem Kreismesser, einer die Schnittstärke bestimmenden in Achsrichtung des Kreismessers verschiebbaren Anschlagplatte, einem parallel zur Anschlagplatte verfahrbaren Schnittgutwagen, auf welchem das Schnittgut gelagert ist, sowie einem abnehmbaren Kettenrahmen mit über zwei Drehachsen umlaufenden Ketten mit Spitzen zum Transport der Schnittgutscheiben vom Kreismesser zu einem Schläger, mittels welchem die Schnittgutscheiben in Richtung eines Ablegebereichs abwerfbar sind, wobei der Kettenrahmen im eingesetzten Zustand mit einer Drehachse mit einer Antriebswelle an der Schneidemaschine verbunden ist und mit zumindest einem weiteren Auflagepunkt am Gehäuse der Schneidemaschine gelagert ist.The invention relates to a cutting machine for food such as sausage, cheese or the like, with a housing, a circular knife, a stop plate which determines the thickness of the slice and which can be displaced in the axial direction of the circular knife, a cut goods carriage that can be moved parallel to the stop plate and on which the cut goods are stored, and a removable chain frame with chains with points rotating over two axes of rotation for transporting the cut slices from the circular knife to a hammer, by means of which the cut slices can be thrown in the direction of a deposit area, the chain frame in the inserted state being connected to a rotary axis with a drive shaft on the cutting machine and with at least one further support point is mounted on the housing of the cutting machine.

Stand der TechnikState of the art

Derartige Schneidemaschinen sind im Frischethekenbereich seit langem bekannt. Neben den einfachen Maschinen mit manueller Ablage des Aufschnitts sind viele Maschinen auch mit einem Kettenrahmen und Schläger ausgestattet. Am Kettenrahmen befinden sich über zwei Drehachsen umlaufende Ketten mit Spitzen. Mittels einer Transportrolle wird die jeweils abgeschnittene Scheibe vom Kreismesser übernommen und auf die Spitzen aufgespießt. Die Scheibe kann so über die Ketten vom Kreismesser weg transportiert werden. Mittels eines Schlägers, der mit seinen einzelnen Armen zwischen den umlaufenden Ketten durchgreifen kann, wird die transportierte Scheibe dann von den Spitzen in Richtung eines Ablegebereichs abgeworfen. Um die laufende Hygiene der Schneidemaschine sicherzustellen, ist es notwendig, den Kettenrahmen regelmäßig gründlich zu reinigen. Zu diesem Zweck kann der gesamte Kettenrahmen von der Schneidemaschine abgenommen werden. Üblicherweise ist der Kettenrahmen an drei Punkten an der Maschine befestigt, nämlich an einer Antriebswelle für die Drehachse der Ketten und an zwei weiteren Punkten zur Lagerung. Der Kettenrahmen hat ein nicht unbeträchtliches Gewicht von mehreren Kilogramm. Speziell bei der Montage des Kettenrahmens nach der Reinigung bedeutet dies, dass die schwere Komponente weit von der Körperachse der Bedienperson weg über den Ablegebereich gehoben werden muss, um anschließend in dieser sehr anstrengenden Lage präzise an den drei Montagepunkten eingesetzt und fixiert zu werden. Da diese Tätigkeit für den Benutzer sehr umständlich und kräfteraubend ist, kommt es in der Praxis dazu, dass die notwendigen Reinigungen für den Kettenrahmen nicht immer ordnungsgemäß durchgeführt werden, was dazu führt, dass die Hygiene der Maschine nicht mehr gewährleistet ist.Such cutting machines have long been known in the fresh food counter area. In addition to the simple machines with manual storage of the slices, many machines are also equipped with a chain frame and beater. On the chain frame there are rotating chains with spikes via two axes of rotation. The slice that has been cut is taken over by the circular knife by means of a transport roller and impaled on the tips. The disc can be transported away from the circular knife via the chains. The transported disc is then thrown from the tips in the direction of a depositing area by means of a mallet, which can reach through between the circulating chains with its individual arms. In order to ensure the ongoing hygiene of the cutting machine, it is necessary to thoroughly clean the chain frame regularly. For this purpose the entire chain frame can be removed from the cutting machine. The chain frame is usually attached to the machine at three points, namely to a drive shaft for the axis of rotation of the chains and at two other points for storage. The chain frame has a no insignificant weight of several kilograms. Especially when assembling the chain frame after cleaning, this means that the heavy component has to be lifted far away from the operator's body axis over the storage area in order to then be precisely inserted and fixed in this very strenuous position at the three assembly points. Since this activity is very cumbersome and exhausting for the user, in practice the necessary cleanings for the chain frame are not always carried out properly, which means that the hygiene of the machine is no longer guaranteed.

Kurzbeschreibung der ErfindungBrief description of the invention

Ziel der vorliegenden Erfindung soll es sein, das Einsetzen des Kettenrahmens für die Bedienperson deutlich zu vereinfachen, wodurch der Komfort bei der Handhabung der Schneidemaschine, im Speziellen was die Reinigung der einzelnen Komponenten betrifft, deutlich verbessert wird. Die entsprechenden Einrichtungen zur Verbesserung des Komforts sollen möglichst einfach gehalten werden, damit die Produktionskosten gering gehalten werden und die Reinigung der einzelnen Elemente an der Maschine einfach ist. Außerdem soll es möglich sein, auch bestehende Schneidemaschinen mit entsprechenden Elementen für die vereinfachte Handhabung des Einsetzens des Kettenrahmens nachzurüsten.The aim of the present invention should be to simplify the insertion of the chain frame for the operator significantly, whereby the comfort in handling the cutting machine, in particular with regard to the cleaning of the individual components, is significantly improved. The corresponding devices for improving comfort should be kept as simple as possible so that production costs are kept low and the individual elements on the machine can be cleaned easily. In addition, it should also be possible to retrofit existing cutting machines with appropriate elements for the simplified handling of inserting the chain frame.

Diese Aufgabe wird durch die vorliegende Erfindung dadurch gelöst, dass zum Einsetzen des Kettenrahmens am Gehäuse zumindest eine im Wesentlichen senkrecht angeordnete Führungsleiste vorgesehen ist, welche an beiden Längsseiten hinterschnittene Führungsbahnen aufweist, die jeweils eine in Richtung des Kreismessers hin versetzte Kröpfung aufweisen, und dass am Kettenrahmen zumindest zwei Führungszapfen mit entsprechenden im eingesetzten Zustand in die Hinterschneidungen der Führungsbahnen eingreifenden seitlichen Vorsprüngen vorgesehen sind. Das Aufsetzen des Kettenrahmens wird dadurch wesentlich erleichtert, da die Bedienperson nur ganz zu Beginn beim Aufsetzen von oben den Kettenrahmen ungefähr mit den beiden Führungszapfen auf die Führungsleiste aufsetzen muss. Durch die beiden Führungszapfen zentriert sich der Kettenrahmen auf der Führungsleiste und wird dann beim weiteren Absenken korrekt in seine endgültige Position bewegt, in welcher dann die weiteren Lagerungspunkte immer korrekt getroffen werden, sowie die Verbindung zur Antriebswelle hergestellt wird. Im endgültig montierten Zustand muss der Kettenrahmen sehr nahe am Kreismesser liegen, da eine Anpressrolle sowie Übernahmekrallen, welche ebenfalls am Kettenrahmen vorhanden sind, unmittelbar im Übernahmebereich der Aufschnittscheibe vom Kreismesser positioniert sein müssen. Durch die Führungsleiste ist es möglich, den Kettenrahmen ohne Gefahr von Kollisionen mit anderen Maschinenteilen von oben aufzusetzen, wonach die Kröpfung dafür sorgt, dass beim Absenken der Kettenrahmen kurz vor der Endlage gezielt in Richtung des Kreismessers verlagert wird.This object is achieved by the present invention in that at least one essentially vertically arranged guide bar is provided for inserting the chain frame on the housing, which has undercut guide tracks on both longitudinal sides, each of which has an offset offset in the direction of the circular knife, and that on the Chain frame at least two guide pins are provided with corresponding lateral projections engaging in the undercuts of the guide tracks in the inserted state. The placement of the chain frame is made much easier because the operator only has to place the chain frame with the two guide pins on the guide bar at the very beginning when placing it from above. Through the two guide pins the chain frame is centered on the guide bar and is then correctly moved into its final position during further lowering, in which the further bearing points are always correctly hit and the connection to the drive shaft is established. In the finally assembled state, the chain frame must be very close to the circular knife, since a pressure roller and transfer claws, which are also available on the chain frame, must be positioned directly in the area where the slice is transferred from the circular knife. The guide bar makes it possible to put the chain frame on from above without the risk of collisions with other machine parts, after which the crank ensures that the chain frame is shifted in the direction of the circular knife shortly before the end position when it is lowered.

Dabei ist es ein weiteres vorteilhaftes Merkmal, dass die hinterschnittenen Führungsbahnen im oberen Endabschnitt, welcher den Einführbereich für die Führungszapfen darstellt, zueinander geneigt ausgebildet sind. Dies erleichtert zusätzlich das Zentrieren des Kettenrahmens an der Führungsleiste. Beim Einsetzen muss nur ungefähr mit den Führungszapfen gezielt werden, sodass die seitlichen Vorsprünge in die Hinterschneidungen der Führungsbahnen eingreifen. Beim weiteren Absenken werden die Führungszapfen dann in die korrekte Bahn gedrängt.A further advantageous feature here is that the undercut guide tracks in the upper end section, which represents the insertion area for the guide pins, are designed to be inclined to one another. This also makes it easier to center the chain frame on the guide rail. When inserting, the guide pins only need to be approximately aimed so that the lateral projections engage in the undercuts of the guideways. When lowering further, the guide pins are then pushed into the correct path.

Gemäß einer bevorzugten Ausführungsform ist es vorgesehen, dass parallel zu den beiden an der Führungsleiste angeordneten Führungsbahnen von diesen beabstandete äußere hinterschnittene Führungsbahnen vorgesehen sind, sodass die Führungszapfen beim Einsetzen des Kettenrahmens innerhalb einer beidseitig hinterschnittenen Nut geführt sind. Dies ermöglicht eine noch sicherere Führung, insbesondere bei besonders schweren oder ausladenden Kettenrahmen, da die Führungszapfen Nuten jeweils beidseitig geführt sind.According to a preferred embodiment, it is provided that parallel to the two guide tracks arranged on the guide rail, outer undercut guide tracks spaced therefrom are provided so that the guide pins are guided within a groove undercut on both sides when the chain frame is inserted. This enables even more secure guidance, especially in the case of particularly heavy or protruding chain frames, since the guide pin grooves are guided on both sides.

Schließlich ist es ein weiteres Merkmal der Erfindung, dass die Kröpfung der Führungsbahnen für den im eingesetzten Zustand näher dem Kreismesser liegenden Führungszapfen in ihrer Höhe gegenüber der Kröpfung der Führungsbahnen für den anderen Führungszapfen weiter nach unten versetzt ist, und dass die beiden Führungszapfen am Kettenrahmen ebenfalls entsprechend in ihrer Höhe versetzt sind, sodass sie bei senkrechtem Absenken des Kettenrahmens nacheinander in die Führungsbahnen aber gleichzeitig in die gekröpften Abschnitte eintreten. Bei der Ausführungsform mit nur einer mittigen Führungsleiste ohne äußere Führungsbahnen ist es vorteilhafter, wenn die Führungszapfen auf der gleichen Höhe liegen, da dann das Aufsetzen und Zentrieren des Kettenrahmens vereinfacht ist. Wenn jedoch die Führungsbahnen in Form von zwei beidseitig hinterschnittenen Nuten ausgebildet sind, dann ist es vorteilhaft, wenn die beiden Führungszapfen in zueinander versetzter Höhe angeordnet sind. Dies erleichtert das Einführen des Kettenrahmens, da nur ein einzelner Führungszapfen zuerst in die betreffende hinterschnittene Nut eingeführt werden muss. Beim Eintauchen des zweiten Führungszapfens findet dann bereits eine gewisse Führung durch die erste hinterschnittene Nut statt, weshalb der zweite Führungszapfen leichter in die korrekte hinterschnittene Nut einführbar ist. Damit der Kettenrahmen beim weiteren Absenken dann auch korrekt in Richtung der Kreismessers hin versetzt wird, sind auch die Kröpfungen der beiden hinterschnittenen Nuten jeweils in ihrer Höhe versetzt, sodass beim Absenken die beiden Führungszapfen gleichzeitig in die Kröpfung eintreten und der Kettenrahmen parallel in Richtung Kreismesser versetzt wird.Finally, it is a further feature of the invention that the height of the offset of the guide tracks for the guide pin, which is closer to the circular knife in the inserted state, is in relation to the height The cranking of the guideways for the other guide pin is further offset downwards, and that the two guide pins on the chain frame are also correspondingly offset in their height so that when the chain frame is lowered vertically, they enter the guideways one after the other but simultaneously enter the cranked sections. In the embodiment with only one central guide bar without outer guide tracks, it is more advantageous if the guide pins are at the same height, since the placement and centering of the chain frame is then simplified. However, if the guideways are designed in the form of two grooves undercut on both sides, then it is advantageous if the two guide pins are arranged at a height offset from one another. This facilitates the insertion of the chain frame, since only a single guide pin first has to be inserted into the relevant undercut groove. When the second guide pin is immersed, a certain amount of guidance takes place through the first undercut groove, which is why the second guide pin can be more easily inserted into the correct undercut groove. So that the chain frame is then correctly offset in the direction of the circular knife when it is lowered further, the crankings of the two undercut grooves are each offset in their height, so that when lowering the two guide pins enter the crank at the same time and the chain frame is offset parallel in the direction of the circular knife becomes.

Beschreibung der AusführungsartenDescription of the types of execution

Bei der in Fig. 1 schematisch dargestellten Schneidemaschine sind der Kettenrahmen und der Schläger zur besseren Ansicht nicht eingezeichnet. Die Schneidemaschine besitzt ein Gehäuse 1, in dem ein Kreismesser 2 zum Schneiden von Stangenware montiert ist. Eine Anschlagplatte 3 ist in Achsrichtung des Kreismessers 2 verschiebbar, um die Schnittstärke der Aufschnittscheiben zu bestimmen. Die aufzuschneidene Stangenware wird auf einem Schnittguwagen 4 platziert, welcher parallel zum Kreismesser 2 verfahrbar ist. Weiters ist am Gehäuse 1 die Antriebswelle 8 zu erkennen, auf welcher der Kettenrahmen 5 (siehe Fig. 2) im eingesetzten Zustand gelagert ist. Zur Stabilisierung wird der Kettenrahmen 5 ferner an einer weiteren Lagerposition 16 gelagert und gesichert. Zum einfachen und gezielten Einsetzen des Kettenrahmens 5 ist am Gehäuse 1 ferner eine Führungsleiste 10 vorgesehen, welche zu beiden Seiten hin jeweils hinterschnittene Führungsbahnen 11 aufweist. In der Ausführungsform gemäß Fig. 1 sind zusätzlich zu den an der Führungsleiste 10 vorgesehenen Führungsbahnen 11 äußere Führungsbahnen 15 vorgesehen, wodurch zwei nebeneinander angeordnete beidseitig hinterschnittene Nuten ausgebildet werden. Die Führungsbahnen weisen jeweils eine Kröpfung 12,13 auf, wodurch beim Einsetzen des Kettenrahmens dieser in Richtung Kreismesser 2 hin versetzt wird. Bei der in Fig. 1 dargestellten Ausführungsform sind die Kröpfungen 12 der näher am Kreismesser liegenden beiden Führungsbahnen 11,15 weiter unten angeordnet als die Kröpfungen 13 der beiden weiter außen gelegenen Führungsbahnen 11,15.At the in Fig. 1 schematically shown cutting machine, the chain frame and the racket are not shown for a better view. The cutting machine has a housing 1 in which a circular knife 2 for cutting bar goods is mounted. A stop plate 3 is displaceable in the axial direction of the circular knife 2 in order to determine the cutting thickness of the slices. The bar goods to be cut are placed on a cutting trolley 4, which can be moved parallel to the circular knife 2. In addition, the drive shaft 8 can be seen on the housing 1, on which the chain frame 5 (see Fig. 2 ) is stored in the inserted state. For stabilization, the chain frame 5 is also stored and secured in a further storage position 16. For the simple and targeted insertion of the chain frame 5, a guide bar 10 is also provided on the housing 1, which has undercut guide tracks 11 on both sides. In the embodiment according to Fig. 1 Outer guideways 15 are provided in addition to the guideways 11 provided on the guide bar 10, whereby two undercut grooves arranged next to one another are formed on both sides. The guideways each have an offset 12, 13, whereby when the chain frame is inserted, it is offset in the direction of the circular knife 2. At the in Fig. 1 In the illustrated embodiment, the crankings 12 of the two guide tracks 11, 15 located closer to the circular knife are arranged further down than the crankings 13 of the two guide tracks 11, 15 located further out.

In Fig. 2 ist schematisch ein Kettenrahmen 5 dargestellt. Zur besseren Ansicht der Drehachse 6 sind nicht alle Ketten 7 eingezeichnet. In der Ansicht ist die Rückseite des Kettenrahmens 5 dargestellt, welche im montierten Zustand am Gehäuse 1 der Schneidemaschine anliegt. Der Kettenrahmen wird im montierten Zustand über die eine Drehachse 6 an der Antriebswelle 8 gehalten und liegt mit einem weiteren Auflagepunkt 9 auf der Lagerposition 16 am Gehäuse 1 auf. Über die Führungszapfen 14, welche seitliche Vorsprünge aufweisen, wird der Kettenrahmen beim Einsetzen in die Führungsbahnen 11,15 am Gehäuse 1 der Schneidemaschine eingeführt. Die beiden Führungszapfen 14 sind bei dieser Ausführungsform in ihrer Höhe versetzt, wodurch zu Beginn des Einsetzvorgangs nur einer der beiden Führungszapfen 14 in die entsprechende hinterschnittene Nut eingeführt werden muss. Beim Eintauchen des zweiten Führungszapfens 14 ist bereits eine gewisse Führung durch die Führungsbahnen 11,15 gegeben, was den weiteren Bewegungsablauf erleichtert. Die inneren Kröpfungen 12 sind zu den äußeren Kröpfungen 13 ebenfalls entsprechend zu den Führungszapfen 14 in ihrer Höhe versetzt, damit der gesamte Kettenrahmen 5 beim Absenkvorgang parallel in Richtung Kreismesser 2 verlagert wird und anschließend mit seiner Drehachse 6 an der Antriebswelle 8 und mit seinem Auflagepunkt 9 und der Lagerposition 16 koppelt.In Fig. 2 a chain frame 5 is shown schematically. For a better view of the axis of rotation 6, not all chains 7 are shown. In the view, the rear side of the chain frame 5 is shown, which in the assembled state rests on the housing 1 of the cutting machine. In the assembled state, the chain frame is held on the drive shaft 8 via one axis of rotation 6 and rests with a further support point 9 on the bearing position 16 on the housing 1. About the guide pins 14, which have lateral projections, the chain frame at Insertion introduced into the guideways 11, 15 on the housing 1 of the cutting machine. In this embodiment, the two guide pins 14 are offset in height, so that only one of the two guide pins 14 has to be inserted into the corresponding undercut groove at the beginning of the insertion process. When the second guide pin 14 is immersed, a certain amount of guidance is already provided by the guide tracks 11, 15, which facilitates the further sequence of movements. The inner crankings 12 are also offset in height from the outer crankings 13, corresponding to the guide pins 14, so that the entire chain frame 5 is displaced parallel in the direction of the circular knife 2 during the lowering process and then with its axis of rotation 6 on the drive shaft 8 and with its support point 9 and the storage position 16 couples.

In der Fig. 3 ist schematisch eine vereinfachte Auführungsform der Führungsleiste 10 dargestellt. Punktiert eingezeichnet sind die beiden hinterschnittenen Führungsbahnen 11 sowie die Führungszapfen 14 in der Position zu Beginn des Einsetzvorgangs. In dieser Ausführungsform mit nur den Führungsbahnen 11 an der Führungsleiste 10 sind die Führungszapfen 14 auf gleicher Höhe montiert, damit ein Aufsetzen auf die Führungsleiste 10 besonders einfach ist. Die Führungsbahnen 11 sind im Einführbereich zueinander geneigt, wodurch sich der Kettenrahmen 5 beim Einsetzen leicht auf die Führungsleiste 10 zentriert. Die Kröpfungen 12,13 der beiden Führungsbahnen 11 sind entsprechend ebenfalls auf der gleichen Höhe angeordnet, damit der Kettenrahmen 5 parallel in Richtung Kreismesser 2 versetzt wird.In the Fig. 3 a simplified embodiment of the guide bar 10 is shown schematically. The two undercut guide tracks 11 and the guide pins 14 in the position at the beginning of the insertion process are shown in dotted lines. In this embodiment with only the guide tracks 11 on the guide bar 10, the guide pins 14 are mounted at the same height so that it is particularly easy to place them on the guide bar 10. The guide tracks 11 are inclined to one another in the insertion area, as a result of which the chain frame 5 is easily centered on the guide bar 10 when it is inserted. The crankings 12, 13 of the two guide tracks 11 are correspondingly also arranged at the same height so that the chain frame 5 is offset parallel in the direction of the circular knife 2.
