Der Gegenstand vorliegender Erfindung istThe object of the present invention is

eine Entfleischungsmaschine zur Gewinnung der zum Verspinnen nutzbaren Fasern von Tropenpflanzen, wie Ramie oder Chinagras, Aloeblätter, Agavenblätter und dergl.a meat removal machine to obtain the fibers that can be used for spinning Tropical plants such as ramie or Chinese grass, aloe leaves, agave leaves and the like.

. Bekanntlich muß zur Gewinnung der nutzbaren Fasern dieser Pflanzen von den Stengeln die Pflanzenrinde, von den Blättern das Blattfleisch entfernt werden. Bei den bis. It is well known that in order to obtain the usable fibers of these plants from the stems the bark of the plant and the flesh of the leaves removed. With the up

ίο jetzt bekannten Anordnungen, den sogenannten Dekortikatoren, geschieht dies auf einem hin- und hergehenden Tisch mit darüber befindlichen Messern.ίο now known arrangements, the so-called Decorators, this is done on a reciprocating table with a table above it Knives.

Das Auf- und Ablegen der Blätter erfordert aber Zeit, und während dieser Zeit arbeiten die Messer nicht. Der Betrieb ist also ein unterbrochener. Bei anderen Dekortikatoren erfolgt die Aussonderung der nicht benutzten Pflanzenteile durch Stoß und Schlag, und die Zuführungsvorrichtung bedingt ein Umspannen der Blätter.Putting the sheets on and off takes time, and work during this time the knives don't. The operation is therefore interrupted. With other decorators the unused parts of the plant are separated out by impact and blow, and the feeding device causes the sheets to be reclamped.

Durch vorliegende Erfindung ist nun eine Entfleischungsmaschine geschaffen, bei der ein ununterbrochener, schlag- und stoßfreier Betrieb stattfindet, und zwar unter Verwendung einer als Auflegetisch dienenden breiten Trommel mit beliebig groß wählbarer Aufnahmefläche, an deren Umfang Messerwalzen arbeiten.By the present invention there is now provided a meat removing machine in which uninterrupted, impact-free and shock-free operation takes place, namely using a wide drum that can be used as a support table and can be of any size, knife rollers are working on their circumference.

Ein Ausführungsbeispiel einer derartigen Maschine ist auf beiliegender Zeichnung dargestellt, und zwar ist Fig. 1 eine Seitenansicht der Maschine mit zum Teil im Quer-. schnitt gezeichneter Auflagetrommel, Fig. 2 eine Hinteransicht, zum Teil im Längsschnitt, Fig. 3 ein Teil des Grundrisses.An embodiment of such a machine is shown in the accompanying drawing, namely Fig. 1 is a side view of the machine with partly transverse. Section of drawn support drum, Fig. 2 is a rear view, partly in longitudinal section, 3 shows part of the floor plan.

In einem kräftigen Rahmen 1 ist die beliebig anzutreibende Welle der breiten Auflegetrommel 3 gelagert, welcher ein Tuch ohne Ende 8 unter Vermittelung einer schräg gestellten Rinne 17 die Blätter zuführt. Diese Rinne ist entsprechend der Anzahl der auf die Trommel in einer Reihe aufzugebenden Blätter eingeteilt. An den Mantel 12 der Trommel 3 schließen sich zu beiden Seiten hervorstehende Flansche H an (Fig. 2). Zwischen diesen Flanschen, die dazu dienen, einer seitlichen Verschiebung der Blätter von der Trommeloberfläche herab vorzubeugen, bewegen sich die Messer der Entfleischungswalzen 4. Fast über die ganze Breite des Mantels reichen Schlitze 13, welche in Aussparungen 29 'übergehen, deren Querschnitt in Fig. ι ersichtlich ist. In diesen Aussparungen bewegen sich Klemmstücke 14, welche im Trommelmantel 12 um Zapfen 15 drehbar gelagert sind und nach dem einen Ende zu in ein schweres Gewicht 16 auslaufen. In a sturdy frame 1 is the arbitrarily driven shaft of the wide lay-up drum 3 stored, which is a cloth without an end 8 through an oblique provided channel 17 feeds the leaves. This gutter is according to the number of on the drum is divided into a series of sheets to be fed. To the coat 12 of the Drum 3 adjoin projecting flanges H on both sides (FIG. 2). Between these flanges, which serve to allow lateral displacement of the sheets of To prevent the drum surface from coming down, the knives of the deflashing rollers move 4. Slits 13, which are in recesses, extend almost over the entire width of the jacket 29 'pass, the cross-section of which can be seen in FIG. In these recesses Clamping pieces 14 move, which in the drum shell 12 around pins 15 are rotatably mounted and run out to one end in a heavy weight 16.

Diese Gewichte 16 beeinflussen die Lage. der Klemmstücke derart, daß jedes Klemmstück in Tätigkeit kommt, sobald die zu behandelnden Blätter bezw. Stengel mit ihren Enden in den Schlitz 13 eingeführt sind, und sich wieder löst, wenn die entfleischten Blätter über das Abführtuch 23 gelangen (Fig. 1). Die Bewegung der Gewichte 16 wird von Schwinghebeln 18 beeinflußt, welcheThese weights 16 influence the position. the clamping pieces such that each clamping piece comes into action as soon as the leaves to be treated respectively. Stems are inserted with their ends into the slot 13, and loosens again when the fleshed leaves pass over the removal cloth 23 (Fig. 1). The movement of the weights 16 is influenced by rocker arms 18, which

Claims

have their fulcrum on the spokes of the drum and their position is adjusted by springs 19 (Fig. 1 and 2). Each weight can only come into its own when a transverse pin 25 attached to the corresponding rocker arms 18 strikes against the fixed stop 26 of the machine frame (FIGS. 1 and 2). Two-part tie rods 2 can be precisely adjusted in their length. Two inclined brushes 21 (FIG. 2) are arranged between the two knife rollers 4, which are used to push the leaves, which have already been partially deflashed by the first deflashing roller 4, towards the center of the drum surface. The removed and thrown away leaf meat is caught by the hoods 22 and then carried away from the machine. Before the stalks and fibers are carried away on the transport cloth 23, any remaining leaf meat is removed by the cylindrical brush 5. The working process is briefly summarized as follows: The worker lays the sheets on the feed cloth 8, in rows next to one another, so that the tips of the sheets are turned backwards. The leaves then fall onto the inclined groove 17, which, as mentioned, is divided according to the width of the leaves, so that the ends of the leaves, separated from one another, reach one of the slots 13 as soon as one of them is rotating during the rotation of the drum 3 has arrived under the channel 17. A moment later the pin 25 strikes the stop 26 and consequently the weight 16 swings around the pin 15 and presses the nose of the clamping piece 14 and thus the sheet ends into the recess 29. The drum 3 continues to rotate slowly, the sheets 31 lay down smoothly down to the circumference against which they are pressed by the pressure roller IO. The leaves 31 now pass the upper pulping roller 4 and are fleshed out almost entirely. The resiliently arranged, inclined brushes 21 then come into operation, which slide over the thicker, already defleaged parts of the leaves, but push the thinner parts at the tips of the leaves together somewhat towards the center of the drum surface. When walking past the lower deflashing roller, these areas are now deflated, because the layer has become a little thicker due to the sweeping together. The fibers and stalks, which have now been completely removed from the meat, are cleaned by the brush drum 5 to remove any meat particles that may still adhere. As the drum continues to rotate, the center of gravity of the clamping piece finally finds a lever arm in a clockwise direction. This position is indicated by the number 24 in FIG. The weight drops on the lever 18 and releases the stem ends. The coil springs 28 brake the movement. In addition, rubber buffers for canceling the impact of the vibrating weight can be arranged on the inner side of the drum shell. As a result of the friction on the cloth 23, the stalks will now remain on the same and be continued with the cloth. In the embodiment of the machine shown here, the rotating drum 3 is set up to accommodate four sets of sheets one behind the other, but of course it can also be set up for more or fewer sets. The circumference of the drum in the present example is four times the length of a "leaf or stem. Patent-A ν Proverbs:
