Die Anschlagschienen (2,3) sind mit Gleitzapfen (9,11) in Lagerböcken (13,15) gelagert und über ein Getriebe aus Hebelarmen (26,27), Steuerwellen (20,21) und Lenkern (28,29) derart miteinander gekuppelt, daß sie gegen die Kraft sie beaufschlagender Federn gleichmäßig auseinanderspreizbar sind, so daß Körper beliebiger Breite zentriert den Trennelementen zugeführt werden. <IMAGE>The invention relates to a separating device for essentially cuboid bodies made of frozen food or feed. For the purpose of centering supply of the body (4) to be separated to separating elements, stop rails (2, 3) which can be moved towards it are arranged on both sides of the body (4) to be guided. The stop rails (2, 3) are mounted with slide pins (9, 11) in bearing blocks (13, 15) and are connected to one another in this way via a gear consisting of lever arms (26, 27), control shafts (20, 21) and links (28, 29) coupled that they can be spread apart evenly against the force of the springs acting on them, so that bodies of any width are centered and fed to the separating elements. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Trennvorrichtung für im wesentlichen quaderförmige Körper aus tiefgefrorenen Lebens- oder Futtermitteln, bestehend aus einem Fördertisch mit seitlichen Anschlagschienen, die einen zu einem oder mehreren Trennelementen führenden Führungskanal für die Körper bilden und die über ein Getriebe miteinander derart gekuppelt sind, daß sie gegen die Kraft einer Feder gleichmäßig auseinanderspreizbar sind.The invention relates to a separating device for essentially cuboid bodies made of deep-frozen food or feed, consisting of a conveyor table with lateral stop rails, which form a guide channel for the bodies leading to one or more separating elements and which are coupled to one another via a gear, that they can be spread apart evenly against the force of a spring.

Bei einer bekannten Trennvorrichtung dieser Art (DE-PS 24 44 139) sind die seitlichen Anschlagschienen von jeweils einer Parallelogrammführung getragen. In den ortsfesten Schwenkachsen eines verschwenkbaren Hebelarms einer jeden Parallelogrammführung ist ein Zahnsegment gelagert, das starr mit dem verschwenkbaren Hebelarm gekuppelt ist. Die Zahnsegmente gegenüberliegender Parallelogrammführungen stehen miteinander im Eingriff und bilden das Getriebe, das die gleichmäßige entgegengesetzte Bewegung der beiden Anschlagschienen gewährleistet. Dadurch wird erreicht, daß jeder zu trennende quaderförmige Körper beliebiger Breite zentriert den Trennelementen zugeführt wird.In a known separating device of this type (DE-PS 24 44 139), the side stop rails are each carried by a parallelogram guide. In the fixed pivot axes of a pivotable lever arm of each parallelogram guide, a toothed segment is mounted, which is rigidly coupled to the pivotable lever arm. The tooth segments of opposing parallelogram guides are in engagement with one another and form the gearbox, which ensures the uniform opposite movement of the two stop rails. This ensures that each cuboid body of any width to be separated is fed centered to the separating elements.

Eine solche Trennvorrichtung hat sich in der Praxis in mehr als einem Jahrzehnt bewährt. Nachteilig ist allein der nicht unerhebliche konstruktive Aufwand für die Parallelogrammführungen und das die Paralellogrammführungen kuppelnde Getriebe.Such a separation device has proven itself in practice in more than a decade. The only disadvantage is the not inconsiderable design effort for the parallelogram guides and the gear coupling that couples the parallelogram guides.

Der Erfindung liegt die Aufgabe zugrunde, eine Trennvorrichtung der eingangs genannten Art zu schaffen, die mit geringerem konstruktiven Aufwand als bei der bekannten Trennvorrichtung die Zentrierung der den Trennelementen zuzuführenden quaderförmigen Körper gewährleistet.The invention has for its object to provide a separating device of the type mentioned, which ensures the centering of the cuboid bodies to be supplied to the separating elements with less design effort than in the known separating device.

Diese Aufgabe wird bei einer Trennvorrichtung der eingangs genannten Art dadurch gelöst, daß jede seitliche Anschlagschiene mit Gleitzapfen in Lagerböcken quer zum Führungskanal verschiebbar gelagert ist, daß die Gleitzapfen einer jeden Anschlagschiene über Kupplungsglieder mit einer längs der Anschlagschiene verlaufenden Steuerwelle verbunden sind und die Steuerwellen beider Anschlagschienen zur gemeinsamen gegensinnnigen Bewegung miteinander gekuppelt sind.This object is achieved in a separating device of the type mentioned above in that each side stop rail with sliding pins is mounted in bearing blocks in a manner transverse to the guide channel, that the sliding pins of each stop rail are connected via coupling members to a control shaft running along the stop rail and the control shafts of both stop rails are coupled together to move in opposite directions.

Bei der Erfindung ist die im Stand der Technik aufwendige Parallelogrammführung durch eine einfache lineare Parallelführung ersetzt. Durch die Kupplung der Gleitzapfen an die Steuerwelle ist gewährleistet, daß ohne Verkantung jede Anschlagschiene exakt parallel verschoben wird.In the invention, the parallelogram guidance, which is complex in the prior art, is replaced by a simple linear parallel guidance. The coupling of the sliding pins to the control shaft ensures that each stop rail is moved exactly parallel without tilting.

Nach einer Ausgestaltung der Erfindung sind die Kupplungsglieder auf der Steuerwelle drehfest sitzende Hebel. Die gegensinnige Bewegung der beiden Steuerwellen läßt sich auf einfache Art und Weise dadurch erreichen, daß die Hebel der einen Steuerwelle über Lenker mit dem einen Arm eines zweiarmigen Hebels und die Hebel der anderen Steuerwelle über Lenker mit dem anderen Arm des zweiarmigen Hebels verbunden sind.According to one embodiment of the invention Coupling links on the control shaft are non-rotatable levers. The opposite movement of the two control shafts can be achieved in a simple manner in that the levers of one control shaft are connected to one arm of a two-armed lever via link and the levers of the other control shaft are connected to the other arm of the two-armed lever via link.

Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert, die eine Trennvorrichtung in schematischer Darstellung zeigt. Im einzelnen zeigen:

die Trennvorrichtung gemäß Figur 1 im Querschnitt nach der Linie I-I der Figur 1.
The invention is explained in more detail below with reference to a drawing, which shows a separation device in a schematic representation. In detail show:
Fig. 1
a separator in supervision and
Fig. 2
1 in cross section along the line II of Figure 1.

Die Trennvorrichtung weist einen Fördertisch 1 auf, auf dem zwei Anschlagschienen 2,3 abstandsveränderlich gelagert sind. Die beiden Anschlagschienen 2,3 bilden zwischen sich einen Führungskanal für einen im wesentlichen quaderförmigen Körper 4, insbesondere aus tiefgefrorenem Lebensmittel. Dieser Körper 4 wird bei seinem Transport in Pfeilrichtung 5 von im Transportweg zwischen den Anschlagschienen 2,3 liegenden Trennelementen 6,7, zum Beispiel Bandsägen, längsgeteilt. Dabei sorgen in noch zu beschreibender Weise die seitlichen Anschlagschienen 2,3 dafür, daß jeder Körper 4 beliebiger Breite zentriert den Trennelementen 6,7 zugeführt wird.The separating device has a conveyor table 1 on which two stop rails 2, 3 are mounted so as to be variable in distance. The two stop rails 2, 3 form between them a guide channel for an essentially cuboid body 4, in particular made of frozen food. This body 4 is longitudinally divided during its transport in the direction of arrow 5 by separating elements 6, 7, for example band saws, located in the transport path between the stop rails 2, 3. The side stop rails 2, 3, to be described below, ensure that each body 4 of any width is centered and fed to the separating elements 6, 7.

Jede Anschlagschiene 2,3 ist von zwei rückseitigen Gleitzapfen 8-11 getragen, die in auf dem Fördertisch 1 positionierten Böcken 12-15 verschiebbar gelagert sind. Die Anschlagschienen 2,3 sind rückseitig von Druckfedern 16,17 beaufschlagt, die an Widerlagern 18,19 abgestützt sind.Each stop rail 2, 3 is supported by two sliding pegs 8-11 on the back, which are slidably mounted in blocks 12-15 positioned on the conveyor table 1. The stop rails 2,3 are on the back of compression springs 16,17 acted on, which are supported on abutments 18,19.

Unterhalb des Fördertisches 1 parallel zu jeder Anschlagschiene 2,3 erstreckt sich eine Steuerwelle 20,21, die in Böcken 22-25 drehbar gelagert ist. Auf jeder Steuerwelle 20,21 sitzt im Bereich der Lagerböcke 12,14 ein einarmiger und im Bereich der Böcke 13,15 ein zweiarmiger Hebel 26, der mit dem zugehörigen Gleitzapfen 8-11 gekuppelt ist. Die zweiarmigen Hebel 26,27 sind außerdem über Lenker 28,29 mit einem zweiarmigen Hebel 30 verbunden, der in einem Lagerbock 31 an der Unterseite des Fördertisches 1 gelagert ist.A control shaft 20, 21 extends below the conveyor table 1 parallel to each stop rail 2, 3 and is rotatably supported in blocks 22-25. On each control shaft 20, 21 there is a one-armed lever 26 in the area of the bearing blocks 12, 14 and a two-armed lever 26 in the area of the brackets 13, 15, which is coupled to the associated sliding pin 8-11. The two-armed levers 26, 27 are also connected via links 28, 29 to a two-armed lever 30, which is mounted in a bearing block 31 on the underside of the conveyor table 1.

Durch die Druckfedern 16,17 wird auf die Anschlagschienen 2,3 eine Kraft ausgeübt, die die Tendenz hat, die beiden Anschlagschienen 2,3 aufeinanderzu zu bewegen. Über die antriebsmäßige Kupplung der beiden Anschlagschienen 2,3 können diese aber nur gemeinsam und gleichmäßig eine Bewegung durchführen, so daß jeder Körper 4 zentriert wird.A force is exerted on the stop rails 2, 3 by the compression springs 16, 17 which tends to move the two stop rails 2, 3 towards one another. Via the drive coupling of the two stop rails 2, 3, however, they can only move together and evenly, so that each body 4 is centered.

Die Länge der Anschlagschienen 2,3 richtet sich nach der Länge der zu trennenden Körper. Wenn die Körper regelmäßig über ihre Länge unterschiedlich breit sind, ist es von Vorteil, die Anschlagschienen 2,3 kürzer als die Länge der Körper auszubilden, weil dann eine individuellere Anpassung an die Körper und damit eine bessere Zentrierung erreicht wird.The length of the stop rails 2,3 depends on the length of the body to be separated. If the bodies are regularly of different widths over their length, it is advantageous to make the stop rails 2.3 shorter than the length of the bodies, because then a more individual adaptation to the body and thus better centering is achieved.
