Abstract

Device which automatically cuts out the black parts from potato chips, beans and other similar shaped vegetables includes a vibrating conveyor belt which singles out the vegetables via V-shaped channels and supplies them to an electronic scanning head and double cutting head which is driven pneumatically to cut off and/or cut out the damaged part. Scanning head can be a reflex photocell which on detecting a dark or discoloured area, sends a pulse to the blade which instantly cuts out the relevant spot. The vegetables can hten pass back into the sorting appts. and be added to the other goods, thereby reducing waste to a minimum whilst keeping labour costs low.

Description

Automatische Fl eckenschnei demaschi ne insbesondereAutomatic patch cutting machines in particular

zum Ausschneiden von Schadstellen an Pommes frites und gleichgeartetem Gemüse Erfindungsgemäßer Gegenstand ist eine Maschine, mit der Flecken, Augen oder schwarze unansehnliche Stellen aus Pomnes frites, Karotten, Spargel, Bohnen u.ä. entfernt werden können.For cutting out damaged areas on French fries and the like Vegetables The subject of the invention is a machine with which spots, eyes or black unsightly spots from french fries, carrots, asparagus, beans etc. can be removed.

Pomnes frites oder ähnlich geformte Gemüsearten werden von Hand oder auch maschinell verlesen. Dieses ist erforderlich, da unansehnliche Stellen, Augen oder Flecken den Verkauf der Ware behindern. Die Auslese beträgt im Schnitt etwa 90 %, so daß 10 Prozent der Ware unbrauchbar wären. Diese aussortierte schlechte Ware ließe sich aber wieder verwenden, wenn die Schadstellen herausgeschnitten würden. Manuell würde diese Tätigkeit zu umständlich und langwierig sein, weshalb das schlechte Produkt bisher aus dem Verkehr gesogen wird. Die benannte Maschine behebt diese Mängel, indem das aussortierte Schlechtprodukt rationell und automatisch behandelt wird und zum Gutprodukt zugegeben werden kann.French fries or similarly shaped vegetables are made by hand or also read by machine. This is necessary because of unsightly spots, eyes or stains hinder the sale of the goods. The selection is on average about 90%, so that 10 percent of the goods would be unusable. This sorted out bad ones However, the goods could be used again if the damaged areas were cut out. Manually this activity would be too cumbersome and tedious, which is why the bad product has been withdrawn from circulation so far. The named Machine remedies these deficiencies by removing the rejected product efficiently and is automatically treated and can be added to the good product.

Aufgabe der Erfindung ist es, das Produkt zu sammeln, in Bahnen zu vereinzeln, dann die schlechten Stellen zu sichten und mittels eines pwamatisch mechanisch betätigten Messers die Schadstellen herauszustanzen.The object of the invention is to collect the product in lanes isolate, then sift through the bad spots and use a pwamatic mechanically operated knife to punch out the damaged areas.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Vlbrationsförderrinne das Produkt, beispielsweise die aussortierten schlechten Pommes frites,aufnimmt. Die Förderrinne ist hierfür mit einer Plattform, auf die das Produkt geschüttet oder geleitet wird, versehen In Auslaufrichtung wird diese Plattform in beispielsweise 6 V-Rinnen so verändert, daß das Produkt über entsprechende Schikanen dort hineinläuft. In den Rinnen sind die Pommes frites nunmehr hintereinandergereiht. An der ausläufigen Seite der Förderrinne sind die V-Rinnen in Form eines Querschlitzes unterbrochen. In diese Unterbrechungen ragen von unten her galgenförmige Messer herein, die die Pommes frites abköpfen.This object is achieved according to the invention in that a Vlbrationsförderrinne the product, for example the rejected bad French fries, takes up. The conveyor trough is for this purpose with a platform on which the product is poured or is directed, provided In the outlet direction, this platform is in for example 6 V-channels changed so that the product runs into them via appropriate baffles. The French fries are now lined up one behind the other in the channels. At the expansive On the side of the conveyor trough, the V-troughs are interrupted in the form of a transverse slot. Gallows-shaped knives protrude into these interruptions from below Skim off the french fries.

Oberhalb des Ausbruches ist eine Reflexfotozelle angebracht, die, sobald eine dukle oder verfärbte Stelle am Pommes frites gesichtet wird, einen Impuls auf das Messer gibt, welches augenblicklich die dunkle Stelle ausschneidet.A reflex photo cell is attached above the eruption, which, as soon as a ducked or discolored area is seen on the french fry, an impulse on the knife, which instantly cuts out the dark spot.

Die so ausgeschnittenen Pommes frites können dann in den Verlesevorgang wieder eingefügt und damit dem Gutprodukt zugeschlagen werden. Solche Pommes frites, die unterseitig noch nicht erfasst wurden, gelangen erneut in die Schneidemaschine, um entsprechend ausgeschnitten zu werden.The French fries cut out in this way can then be used for the sorting process reinserted and thus added to the good product. Such fries which have not yet been captured on the underside are returned to the cutting machine, to be cut out accordingly.

In der Beschreibung ist ein Ausführungsbei9iel der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigt: Fig. 1 - einen Längsschnitt der gesamten Maschine mit der Förderri nne Fig. 2 - einet Draufsicht auf die Maschine Fig. 3 - einen Querschnitt an der Messermechanik.In the description, an embodiment of the invention is under Referring to the drawings explained in more detail. It shows: Fig. 1 - a longitudinal section the entire machine with the conveyor belt Fig. 2 - a top view of the machine Fig. 3 - a cross section on the knife mechanism.

Nach den in Fig. 1 und 2 dargestellten Ansichten werden die Pommes frites auf die Plattform 1 eines Vibrationsförderers 2 z.B. über eine Schütte 3 aufgegeben. Hier liegen die Pommes frites wahllos durcheinander und marschieren in Pfeilrichtung durch die Fördervibration über Schikanen 4 in V-Rinnen 5 zum Durchbruch 6. Oberhalb des Durchbruches 6 -sind Fotozellen bzw. Farbmarkiertastköpfe 7 angebracht, die die Fleckenauf den Pommes frites erkennen und einen Impuls an ein Ventil oder Schalter 8 abgeben. Dieser Impuls bewirkt, daß ein Doppel messer 9 heruntergezogen und das Produkt von hinten oder Mitte, wie von der Fotozelle 7 erkannt, ab- oder ausgeschnitten wird.According to the views shown in Fig. 1 and 2, the fries fries on platform 1 of a vibratory conveyor 2, e.g. via a chute 3 given up. Here the french fries are randomly mixed up and marching in the direction of the arrow by the conveying vibration via baffles 4 in V-grooves 5 to the breakthrough 6. Above the opening 6 - photocells or color marking probe heads 7 are attached, who recognize the stains on the french fries and an impulse a Release valve or switch 8. This pulse causes a double knife 9 pulled down and the product from behind or in the middle, as recognized by the photocell 7, from or is cut out.

Die abgeschnittenen Teile, das sind die Flecken oder Augen werden mittels Auswerfer 10 (Fig. 3) in den Durchbruch 6 geworfen. Hier werden die Stückchen durch Sprührohre 11 in die Rinne 13 ausgespült.The cut off parts, these are the spots or eyes thrown into the opening 6 by means of the ejector 10 (FIG. 3). Here are the bits rinsed through spray pipes 11 into the channel 13.

Die von den Flecken befreiten Pommes frites wandern in der V-Rinne 5 zum Auslauf 14. Gleichzeitig wandern zu kurze Pommes frites-Stückchen in ddn Durchbruch 6 und werden somit aussortiert. Diese zu kurzen Ende entstehen, wenn die Messer vorm Ende der Pommes frites eine Schadstelle heraustrennen. Damit ganze Pommes frites, die durch Spannungen leicht gebogen sein können, nicht verklemmen, ist die hintere V-Rinne 15 etwas tiefer angebracht als die vordere V-Rinne 5.The French fries freed from the stains move in the V-groove 5 to the outlet 14. At the same time, pieces of French fries that are too short move into the opening 6 and are thus sorted out. This too short end occurs when the knife Cut out a damaged area before the end of the french fries. So that whole french fries, which can be easily bent by tension, do not jam, is the rear one V-channel 15 installed a little lower than the front V-channel 5.

Ein Verhaken oder Bremsen ist dadurch ausgeschlossen. Um eine gute Vereinzelung zu gewährleisten, sind in der V-Rinne 5 Schleppen 16 angebracht, die nur immer ein Pommes frites am Grund der V-Rinne durchlassen. Die Schleppen können aus Kunststoff oder Metall sein und sind auf einer Achse 17 zwecks Anpassung an die Pommes frites-Dicke schwenkbar gelagert.This rules out getting stuck or braking. To be good To ensure isolation, 5 tows 16 are attached in the V-channel, the only ever let one french fry through at the bottom of the V-channel. The tow can Be made of plastic or metal and are on an axis 17 for the purpose of adaptation the thickness of the French fries can be pivoted.

In Fig. 3 ist die Messermechanik dargestellt. Diese Messer 9 sind in einem Bock 18 so angebracht, daß sie über eine Schraube 19 von oben her leicht ausgewechselt werden können. Der Bock 18 ist an einem Pneumatikzylinder oder auch Elektromagneten 20 befestigtdCommt der Zylinder über das Ventil 8 seinen Impuls, so wird der Bock 18 heruntergezogen und das in den V-Rinnen 5 und 15 liegende Pommes frites wird ausgeschnitten oder vorn bzw.hinten geköpft.In Fig. 3 the knife mechanism is shown. These knives 9 are Mounted in a bracket 18 so that it can be easily accessed via a screw 19 from above can be exchanged. The bracket 18 is on a pneumatic cylinder or else Electromagnet 20 attached. If the cylinder receives its impulse via valve 8, so the block 18 is pulled down and the french fries lying in the V-grooves 5 and 15 fries are cut out or decapitated at the front or back.

Jeweils wo die Schadstelle liegt. Mit dem Abwärtsgang des Messers wird ebenfalls ein zwischen den Messern liegender Auswerfer 10, gelagert in derFührungsstange 22, über Feder 23 heruntergezogen, stößt dabei durch die Messer 9 hindurch gegen das ausgestanzte Stück Pommes frites und schlägt dieses in die Abflußrinne 13. Wogegen die nun untenstehenden Messer das andere in den V-Rinnen 5 und 15 liegende Produkt absperren, indem die Messer noch bis zur Hälfte in die Rinnen hineinragen. Die Führungsstange 22 dient nicht nur als Lagerung des Auswerfers, sondern gleichzeitig wird der Bock 18 mit dieser Stange gegen Verdrehen in der Weise gesichert, daß die Führungsstange 22 durch einen paßgerechten Ausschnitt in den Bock 18 eintaucht. Die Bewegung des Auswerfers ;Ff nach oben erfolgt durch den Bock 18, indem dleser gegen den Auswerferhebel stößt, der sich damit hochhebt und die Feder 23 spannt.In each case where the damaged area is. With the downward gear of the knife an ejector 10, located between the knives, is also stored in the guide rod 22, pulled down via spring 23, pushes through the knife 9 through it the punched-out piece of French fries and hits this into the drainage channel 13. Against this the knives below the other product lying in the V-grooves 5 and 15 shut off by the knives sticking halfway into the gutters. The guide bar 22 not only serves as a storage for the ejector, but also serves as the bracket 18 with this rod secured against rotation in such a way that the guide rod 22 dips into the bracket 18 through a fitting cutout. The movement of the Ejector; Ff upwards is carried out by the bracket 18 by pushing the reader against the ejector lever who lifts himself up with it and the spring 23 tensions.

Die Messer 9 sind doppelt ausgeführt, so daß sie einmal als Stanzwerkzeug schneiden und zum anderen vorn oder jeweils hinten mit nur einem Messer schneiden können. Dabei ist es gleich, ob die Messer je einen Einzel- oder gemeinsamen Antrieb haben.The knives 9 are designed twice so that they can be used once as a punching tool cut and cut to the other at the front or at the back with just one knife can. It does not matter whether the knives each have a single drive or a common drive to have.

Ob die Maschine nach Fig. 1 und 2 ein eigenes Grundgestell hat, ist für die Funktion ohne Bedeutung, sie kann sowohl als Einbaugerät wie auch als Sologerät verwendet werden.Whether the machine according to FIGS. 1 and 2 has its own base frame is irrelevant for the function, it can be used as a built-in device or as a stand-alone device be used.
