Abstract
Description
Die Erfindung betrifft ein Gatter zum Schneiden von Speck, Fleisch, Wurst und dergleichen Waren mit zwei Gruppen von in gleichmäßigem Abstand parallel zueinander angeordneten Messern unterschiedlicher Länge. Jede Gruppe aus Messern der gleichen Länge ist innerhalb eines Spannrahmens aus zwei Querschenkeln und zwei diese auf Abstand haltenden Längsschenkeln so eingespannt, daß einem längeren Messer der einen Gruppe jeweils ein kürzeres Messer der anderen Gruppe folgt. Die Spannrahmen sind mit mindestens einem Antrieb versehen, durch den die längeren Messer der einen Gruppe gegenläufig zu den kürzeren Messern der anderen Gruppe bewegbar sind.The invention relates to a creel for cutting bacon, meat, sausage and the like goods with two groups of knives of different lengths arranged parallel and at equal intervals from one another. Each group of knives of the same length is clamped within a stenter frame made up of two cross legs and two longitudinal legs that keep these at a distance such that a longer knife in one group is followed by a shorter knife in the other group. The clamping frames are provided with at least one drive, by means of which the longer knives of one group can be moved in opposite directions to the shorter knives of the other group.
Für eine Speckwürfelschneidmaschine ist ein derartiges Gatter aus der DE-A-145 710 bekannt. Durch die einzeln oder paarweise in entgegengesetzter Bewegungsrichtung arbeitenden Messer einer Messergruppe soll das Schneiden des Specks erleichtert und dabei dessen seitliche Verschiebung vermieden werden. Zur unbehinderten Hin- und Herbewegung der längeren Messer der einen Gruppe, die zwangsläufig die Querschenkel des Spannrahmens der kürzeren Messer der anderen Gruppe überragen, sind die beiden Messergruppen des bekannten Gatters in unterschiedlichen, in Vorschubrichtung aufeinanderfolgenden Ebenen angeordnet. Auch wenn der senkrechte Abstand zwischen diesen Ebenen nicht wesentlich größer sein muß als die Flankenbreite der längeren Messer bzw. als die Breite der Querschenkel, an denen die Messer befestigt sind, um eine unbehinderte Hin- und Herbewegung zu gewährleisten, bewirkt diese Anordnung, daß die erste Messergruppe, worauf das zu schneidende Gut auftrifft, dieses jeweils in die eine Richtung verschiebt, während die zweite Messergruppe das zu schneidende Gut jeweils in die andere Richtung verschiebt. Abgesehen von den je nach Labilität unerwünscht großen Hin- und Herverschiebungen der Scheiben bzw. der Streifen des Schneidguts besteht dabei die Tendenz, daß die zweite Verschiebung die erste überkompensiert, da die Scheiben bzw. Streifen von der in Vorschubrichtung zweiten Messergruppe weiter unterteilt werden und daher ihre etwa zuvor noch vorhandene, ohnehin begrenzte Eigensteifigkeit zunehmend einbüßen. Sollen sodann aus den Scheiben Streifen oder aus den Streifen Würfel geschnitten werden, fehlt es diesen an einer Geometriegenauigkeit, welche als Qualitätsmerkmal angesehen wird. Jede Hin- und Herverlagerung des zu schneidenden Guts beeinträchtigt aber auch die Schneidleistung und bewirkt schließlich auch eine Verzerrung der Fasern eines empfindlichen Schneidguts.Such a gate is known from DE-A-145 710 for a bacon cube slicer. The knives of a group of knives, which work individually or in pairs in opposite directions of movement, are intended to facilitate the cutting of the bacon and thereby to avoid its lateral displacement. For the unobstructed reciprocation of the longer knives of one group, which inevitably protrude beyond the transverse legs of the tenter frame of the shorter knives of the other group, the two knife groups of the known gate are arranged in different, successive planes in the direction of advance. Even if the vertical distance between these planes does not have to be significantly larger than the flank width of the longer knives or the width of the cross legs to which the knives are attached in order to ensure an unobstructed back and forth movement, this arrangement causes that the first group of knives, whereupon the good to be cut, shifts it in one direction, while the second group of knives shifts the good to be cut in the other direction. Apart from the undesirable large back and forth displacements of the disks or strips of the material to be cut, there is a tendency that the second displacement overcompensates for the first, since the disks or strips are further subdivided by the second knife group in the direction of advance and therefore increasingly lose their inherent stiffness, which was already there and was already limited. If strips are then to be cut from the slices or cubes, these lack a geometric accuracy, which is regarded as a quality feature. Any back and forth movement of the material to be cut also impairs the cutting performance and ultimately also distorts the fibers of a sensitive material to be cut.
Aus der US-A-2 036 403 ist eine Brotschneidemaschine bekannt, die gleichfalls mit in entgegengesetzten Bewegungsrichtungen arbeitenden Messern ausgestattet ist. Während die Messer der einen Gruppe in die eine Richtung bewegt werden, werden die Messer der anderen Gruppe in die entgegengesetzte Richtung bewegt. Bei dieser bekannten Schneidmaschine lassen sich jedoch die Messer zu Reinigungs- und Wartungszwecken nur mit erheblichem Aufwand de- und remontieren.From US-A-2 036 403 a bread slicer is known which is also equipped with knives working in opposite directions of movement. While the knives of one group are moved in one direction, the knives of the other group are moved in the opposite direction. In this known cutting machine, however, the knives can only be removed and reassembled for cleaning and maintenance purposes with considerable effort.
Der Erfindung liegt die Aufgabe zugrunde, ein Gatter der eingangs beschriebenen Art so auszubilden, daß die aus der Bewegung eines jeden Messers infolge der Reibung zwischen den Flanken des Messers und den Schnittflächen des Schneidguts resultierende Verschiebungskraft unmittelbar durch eine entgegengesetzte Verschiebekraft kompensiert wird, die aus einer zeitgleichen Bewegung gleicher Größe und Geschwindigkeit benachbarter Messer resultiert, wobei das Gatter so ausgebildet sein soll, daß der Spannrahmen für die Messer mit diesen in einfacher Weise bestückt und davon zu Reinigungs- und Wartungszwecken befreit werden kann.The invention has for its object to form a gate of the type described in such a way that the displacement force resulting from the movement of each knife as a result of the friction between the flanks of the knife and the cut surfaces of the material to be cut is compensated directly by an opposing displacement force resulting from a simultaneous movement of the same size and speed of adjacent knives results, the gate being designed so that the clamping frame for the knives can be fitted with them in a simple manner and freed from them for cleaning and maintenance purposes.
Zur Lösung dieser Aufgabe wird von einem Gatter der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welches erfindungsgemäß die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale aufweist.To achieve this object, a gate of the generic type mentioned in the preamble of
Durch die entsprechend dem Abstand der längeren Messer in den Querschenkeln des Spannrahmens der kürzeren Messer vorgesehenen Schlitze kann die Gruppe der längeren Messer in der gleichen Ebene der Gruppe der kürzeren Messer angeordnet werden, ohne daß sich die gegenläufig angetriebenen Messergruppen oder ihre Spannrahmen behindern. Die Schlitze in den Querschenkeln des Spannrahmens der kürzeren Messer definieren quaderförmige, in die Zwischenräume der längeren Messer hineinragende Vorsprünge. Diese bieten sich dazu an, ihrerseits jeweils mit einem Schlitz versehen zu werden, worin sich ein kürzeres Messer mit einem Endstück einführen und durch einen den Schlitz kreuzenden Spannbolzen fixieren läßt, der in einer Bohrung des quaderförmigen Vorsprunges sitzt. Während die längeren Messer der einen Gruppe an ihren Enden jeweils in Schlitzen der Querschenkel ihres Spannrahmens durch einen die Schlitze kreuzenden durchgehenden Spannbolzen gehalten sein könnten, ist es unerläßlich, die kürzeren Messer der anderen Gruppe an ihren beiden Enden jeweils in den Schlitzen der quaderförmigen Vorsprünge durch jedem Messer für sich zugeordnete Spannbolzen zu halten. Ein durchgehender, der Gruppe der kürzeren Messer gemeinsamer Spannbolzen würde dagegen die Gruppe der längeren Messer kreuzen und in diesen zu ihrer unbehinderten Hin- und Herbewegung langgestreckte Durchbrüche erfordern. Abgesehen vom dazu erforderlichen Fertigungsaufwand verbieten es die hohen Spannkräfte, welchen die Messer ausgesetzt sind, darin derartige Durchbrüche vorzusehen. Der gemeinsame Führungsrahmen für die Messer beider Gruppen stellt sicher, daß alle Messer unabhängig von ihrer Länge in den Schlitzen der Querschenkel des Führungsrahmens nicht nur in der gleichen Ebene, sondern auch im gleichen Längenabstand hinreichend sicher geführt sind und dadurch die längeren Messer die gleiche Formstabilität beibehalten können wie die kürzeren Messer. Durch die Zusammensetzung des Führungsrahmens aus lösbar miteinander verbundenen Rahmenteilen läßt sich der Führungsrahmen und damit das Gatter insgesamt insbesondere zu Reinigungszwecken in einfacher Weise zerlegen und wieder zusammensetzen. Dies erleichtern die winkelförmigen Schlitze in der Nähe der Messerenden, wodurch die Messer bajonettverschlußartig mit den Verriegelungsbolzen verbindbar sind, welche die Aufnahmeschlitze in den Querschenkeln der Spannrahmen kreuzen.Due to the slots provided in accordance with the distance between the longer knives in the transverse legs of the tenter frame of the shorter knives, the group of longer knives can be arranged in the same plane of the group of shorter knives without the counter-driven knife groups or their tenter frames being impeded. The slots in the transverse legs of the clamping frame of the shorter knives define cuboid projections that protrude into the spaces between the longer knives. These lend themselves, in turn, to be provided with a slot, in which a shorter knife with an end piece can be inserted and fixed by a clamping bolt crossing the slot, which sits in a bore in the cuboid projection. While the longer knives of one group could be held at their ends in slots in the cross legs of their tenter frame by a continuous clamping bolt crossing the slots, it is essential to pass the shorter knives of the other group at both ends in the slots of the cuboid projections to hold each knife for its own clamping bolts. A continuous clamping bolt common to the group of shorter knives would, on the other hand, cross the group of longer knives and require elongated openings in them for their unobstructed back and forth movement. Apart from the manufacturing effort required for this, the high clamping forces to which the knives are exposed prohibit such openings. The common guide frame for the knives of both groups ensures that all knives, regardless of their length in the slots of the cross legs of the guide frame, are sufficiently securely guided not only in the same plane, but also at the same length spacing, and thereby the longer knives maintain the same dimensional stability can like the shorter knives. Due to the composition of the guide frame from releasably connected The guide frame and thus the gate as a whole can be dismantled and reassembled in a simple manner, in particular for cleaning purposes. This facilitates the angular slots in the vicinity of the knife ends, as a result of which the knives can be connected in a bayonet-like manner to the locking bolts which cross the receiving slots in the transverse legs of the clamping frame.
Nach einer Ausgestaltung der Erfindung kann der Führungsrahmen mit Bohrungen versehen sein, in welchen die als Spannsäulen ausgebildeten Längsschenkel der Spannrahmen hin- und herverschiebbar sind.According to one embodiment of the invention, the guide frame can be provided with bores in which the longitudinal legs of the clamping frame, which are designed as tensioning columns, can be pushed back and forth.
Der vorzugsweise aus zwei kongruenten, sich überdeckenden Rahmenteilen bestehende Führungsrahmen kann in an sich bekannter Weise leicht lösbar am Ausgang eines Führungsschachtes einer Schneidmaschine so befestigt sein, daß das Spannrahmenpaar zusammen mit dem Führungsrahmen als Baueinheit in einfacher Weise de- und remontierbar ist.The guide frame, which preferably consists of two congruent, overlapping frame parts, can be fastened in a manner known per se at the outlet of a guide shaft of a cutting machine in such a way that it can be easily removed and dismantled together with the guide frame as a structural unit.
Je nach den Platzverhältnissen und dem Erfordernis, das erfindungsgemäße Gatter mit einem ebenso ausgebildeten Gatter so zu kombinieren, daß sich jeweils die beiden Messergruppen des einen Gatters mit den beiden Messergruppen des anderen Gatters kreuzen, um das Schneidgut zunächst in Scheiben und sodann in Streifen zu schneiden, kann es vorteilhaft sein, die als Spannsäulen ausgebildeten Längsschenkel beider Spannrahmen in der Ebene der Messergruppen jeweils nebeneinander oder senkrecht zur Ebene der Messergruppen hintereinander anzuordnen.Depending on the space available and the need to combine the gate according to the invention with a gate of the same design so that the two knife groups of one gate cross with the two knife groups of the other gate to cut the material to be cut first into slices and then into strips , It can be advantageous to arrange the longitudinal legs of the two clamping frames, which are designed as clamping columns, in the plane of the knife groups next to one another or perpendicular to the plane of the knife groups one behind the other.
Bei einer Anordnung der Längsschenkel beider Spannrahmen senkrecht zur Ebene der Messergruppen hintereinander müssen die Querschenkel des Spannrahmens, dem die kürzeren Messer zugeordnet sind, mit einem Einspannbereich für die Messer in die Ebene des Spannrahmens hineinragen, dem die längeren Messer zugeordnet sind. Dadurch entsteht infolge der Messerspannung an den Querschenkeln des Spannrahmens der kürzeren Messer ein Drehmoment um die Längsachse dieser Querschenkel. Zur Kompensation dieses Drehmoments sieht eine weitere Ausgestaltung der Erfindung vor, daß jedem auf Druck beanspruchten Längsschenkel des Spannrahmens der kürzeren Messer ein auf Zug beanspruchter, gleichfalls als Spannsäule ausgebildeter Längsschenkel zugeordnet ist. Dabei sind die auf Druck beanspruchten Längsschenkel in einer Ebene angeordnet, die zwischen den Ebenen liegt, in welchen die auf Zug beanspruchten Längsschenkel bzw. die Messer angeordnet sind.If the longitudinal limbs of both clamping frames are arranged one behind the other perpendicular to the plane of the knife groups, the transverse limbs of the clamping frame, to which the shorter knives are assigned, must protrude into the plane of the clamping frame, to which the longer knives are assigned, with a clamping area for the knives. As a result of the knife tension on the cross legs of the clamping frame of the shorter knives, a torque arises around the Longitudinal axis of this cross leg. To compensate for this torque, a further embodiment of the invention provides that each longitudinal leg of the tensioning frame of the shorter knife which is subjected to pressure is assigned a longitudinal leg which is also subjected to tension and is designed as a tensioning column. The longitudinal legs that are subjected to pressure are arranged in a plane that lies between the planes in which the longitudinal legs or the knives that are subjected to tension are arranged.
Schließlich können die beiden Spannrahmen eines Gatters mit je einem Einzelantrieb oder aber auch mit einem gemeinsamen Antrieb versehen sein. Zur Übertragung der Antriebskraft weist je ein Querschenkel der beiden Spannrahmen ein Lagerauge auf, in das ein Kupplungsbolzen eines Kurbeltriebes oder dergleichen eingreift.Finally, the two clamping frames of a gate can each be provided with an individual drive or else with a common drive. To transmit the driving force, one cross leg of each of the two clamping frames has a bearing eye into which a coupling pin of a crank mechanism or the like engages.

Das Gatter besteht im wesentlichen aus einem Spannrahmen 1 und einem Spannrahmen 2 sowie einem Führungsrahmen 3.The gate essentially consists of a
Der Spannrahmen 1 ist aus zwei Querschenkeln 4 und aus zwei als längenveränderliche Spannsäulen ausgebildeten Schenkeln 5 zusammengesetzt. Der in Vorschubrichtung des zu schneidenden Guts dem Spannrahmen 1 nachgeordnete Spannrahmen 2 besteht aus zwei Querschenkeln 6 und zwei gleichfalls als längenveränderliche Spannsäulen ausgebildeten Längsschenkeln 7. Die Längsschenkel 7 des Spannrahmens 2 überragen die Längsschenkel 5 des Spannrahmens 1 an beiden Enden.The
Der Spannrahmen 1 ist mit Messern 8 bestückt, die in gleichmäßigen Abständen verteilt über die Länge der Querschenkel 4 angeordnet und senkrecht zu diesen ausgerichtet sind, wobei die Messer 8 mit Endstücken in Aufnahmeschlitze 9 der Querschenkel 4 eingeführt sind und darin durch Verriegelungsbolzen 10 gehalten werden.The
Der Spannrahmen 2 ist mit Messern 11 bestückt, welche zwischen den Messern 8 in gleichmäßiger Verteilung über die Länge der Querschenkel 6 gleichfalls senkrecht zu diesen angeordnet sind, wobei die Messer wiederum mit Endstücken in Aufnahmeschlitze 12 der Querschenkel 6 eingeführt sind und darin durch Verriegelungsbolzen 13 gehalten werden.The
Die Messer 11 überragen die Enden der Messer 8 und kreuzen folglich die Querschenkel 4 des Spannrahmens 1.The
Um dennoch die Messer 8 und 11 in der gleichen Ebene anordnen zu können, sind die Querschenkel 4 des Spannrahmens 1 im Kreuzungsbereich der Messer 11 mit Schlitzen 14 versehen, durch welche die Messer 11 unbehindert hindurchbewegbar sind.In order nevertheless to be able to arrange the
Der an einer nicht dargestellten Schneidmaschine anschließbare Führungsrahmen 3 kreuzt mit zwei Querschenkeln 15 die Messer 8 und 11, weswegen die Querschenkel 15 gleichfalls mit Schlitzen 16 für die Messer 8 und 11 versehen sind. Der Führungsrahmen 3 ist mit Bohrungen 17 ausgestattet, worin die zylindrischen Längsschenkel 5 und 7 der Spannrahmen 1 bzw. 2 auf- und abbewegbar sind.The

Da die Längsschenkel 5 des Spannrahmens 1 nicht in der gleichen Ebene wie die Längsschenkel 7 des Spannrahmens 2, sondern in Vorschubrichtung des zu schneidenden Guts hintereinanderangeordnet sind, stehen die Querschenkel 4 des Spannrahmens 1 mit einer Längshälfte so in die Ebene des Spannrahmens 2 vor, daß die Verriegelungsbolzen 10 der Messer 8 in der gleichen Ebene liegen, wie die Verriegelungsbolzen 13 der Messer 11.Since the
Jedem infolge der Messerspannung auf Druck beanspruchten Längsschenkel 5 des Spannrahmens 1 ist auf seiner den Messern 8 abgewandten Seite ein zusätzlicher, gleichfalls zylindrischer Längsschenkel 5' zugeordnet, der auf Zug beansprucht ist.
