Die Erfindung betrifft eine Maschine zum Schneiden von Brot, Fleisch u. dgl. mit einem langsam hin- und schnell zurückschwingenden, sich drehenden Kreismesser.
Das Wesen der Erfindung besteht darin, daß das Messer selbst während des Schneidganges eine raschere Drehbewegung um seine eigene Achse ausführt als beim Rückgang. Hierdurch wird die Schneidkraft der Maschine erhöht und erreicht, daß die Maschine so rasch schneidet, wie wenn die Schneide sowohl während des Schneidganges als auch beim Rückgang gleich rasch bewegt würde.The invention relates to a machine for cutting bread, meat and the like with a rotating circular knife that swings slowly back and forth.
The essence of the invention consists in the fact that the knife itself executes a more rapid rotary movement about its own axis during the cutting process than during the return. This increases the cutting force of the machine and ensures that the machine cuts as quickly as if the cutting edge were moved at the same speed both during the cutting pass and during the decrease.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt.The subject of the invention is shown in the drawing.

Fig. ι ist eine Seitenansicht der Schneidmaschine, wobei das Kurbelrad und die von Hand aus zu bewegenden Teile weggelassen sind und das Messer am Ende des Schneidganges steht.Fig. Ι is a side view of the cutting machine, The crank wheel and the parts to be moved by hand are omitted and the knife at the end of the cutting pass stands.

Fig. 2 ist eine gleiche Seitenansicht, zeigt aber das Messer zu Beginn des Schneidganges. Fig. 2 is a similar side view, but shows the knife at the beginning of the cutting pass.

Fig. 3 zeigt die Maschine in lotrechtem Querschnitt nach Linie x-x der Fig. 2. ,Fig. 3 shows the machine in a vertical cross section along line xx of Fig. 2.,

Die Grundplatte 1 ist mit einem aufwärts reichenden Rahmen 7 versehen, welcher das Getriebe für die Schneidvorrichtung usw. trägt. Der Rahmen 7 ist verbreitert und auf einer Seite mit einer Öffnung 8 versehen, durch welche das Schneidgut von dem Zuführungsschlitten geschoben wird. Die Unterkante der Öffnung 8 liegt mit dem den Zuführungsschlitten tragenden Tisch- 5 in. einer Wagerechten, ist mit einem nach außen stehenden wagerechten Flansch 9 aus hartem Stahl versehen und bildet jene Fläche, gegen welche das sich drehende Messer beim Schneiden wirkt. Seitlich von der Öffnung 8 ist der Rahmen. 7 mit einem Arm 10 versehen, in welchem die Welle 11 gelagert ist, die auf der Innenseite des Armes IO ein Triebrad 12 trägt. An der Außenseite des Armes 10 ist die Welle 11 mit einem Kurbelrade 13 versehen, das mittels des Handgriffes 14 gedreht wird, um das Messer zu bewegen. Der Arm 10 ist oben mit dem aufwärts reichenden gekrümmten Ansatz 15 versehen (Fig. 2), in dem eine Welle 16 gelagert ist-, auf die an der Außenseite des Ansatzes ein Zahnrad 17 aufgekeilt ist, das in das Triebrad 12 eingreift. Das Zahnrad 17 trägt auf seiner Innenseite ein größeres Zahnrad 18, das mit einem Trieb- rad 19 in Eingriff steht, welches lose auf der Welle 20 sitzt. Die Welle 20 (Fig. 3) ist in einem länglichen Lager 21 gelagert, das einen Teil des oberen Endes des Rahmens 7 bildet. Das Triebrad 19 ist mit einer länglichenThe base plate 1 is provided with an upwardly reaching frame 7, which Gear for the cutting device, etc. carries. The frame 7 is widened and on a Side provided with an opening 8 through which the material to be cut is pushed from the feed carriage. The lower edge of the Opening 8 is on the horizontal plane with the table 5 carrying the feed carriage, is provided with an outwardly horizontal flange 9 made of hard steel and forms the surface against which the rotating knife acts when cutting. The side of the opening 8 is the Frame. 7 is provided with an arm 10 in which the shaft 11 is mounted on the inside of the arm IO carries a drive wheel 12. On the outside of the arm 10 is the shaft 11 is provided with a crank wheel 13, which is rotated by means of the handle 14 to move the knife. The arm 10 is provided at the top with the upwardly extending curved extension 15 (Fig. 2), in which a shaft 16 is mounted on which a gear 17 is keyed on the outside of the extension is that engages the drive wheel 12. The gear 17 carries on its inside a larger gear 18, which is in engagement with a pinion 19, which loosely on the Shaft 20 is seated. The shaft 20 (Fig. 3) is mounted in an elongated bearing 21, the one Forms part of the upper end of the frame 7. The drive wheel 19 is elongated with an

Claims

Sleeve 22 connected, which carries at its inner end a sprocket 23 releasably fastened on its flange 24 by means of screws 25. A downwardly directed arm 26 is seated on the shaft 20 between the chain wheel 23 and the elongated bearing 21 and is held on the shaft 20 by means of a screw 261 and a pin 202 seated on the shaft. The arm is curved outwards at 27 for the free passage of the knife. Its lower end 28 is bent outwards and provided with an opening for receiving the shaft 29, which can be adjusted in this opening as a result of eccentric mounting so that the shaft 29 can be moved closer to or removed from the axis of rotation 20 of the arm 26 for the purpose of tension or loosening of the chain 33 running over the sprockets 23, 32. At the inner end of the sleeve 30, a disk-shaped knife holder 31 is attached, which carries the cutting disk. The knife is set in rapid rotation by the chain 33 by means of the sprocket 32 and the sleeve 30. On the inside of the approach 15 is the. Shaft 16 is provided with a crank arm 34, "the outer end of which is articulated to a link 35 which is connected to the arm 26, specifically at 36. The arm 26 is moved back and forth in front of the opening 8 by this crank mechanism. According to FIG 1, the knife is at the end of the cutting pass and the continued rotation of gear 17 causes the pivot point between arms 34 and 35 to come out of dead center position so that link 35 allows arm 26 to fall back the arm 26 with the knife back more quickly and past the opening 8 than it was moving forward one that the knife will rotate more slowly during its retreat than during its forward movement, whereby the cutting effect of the knife is increased during the forward movement Godfather νϊ-Αν spokes:

1. Machine for cutting meat, bread and other fabrics with a slow rotating circular knife that swings back and forth quickly, characterized in that that the knife executes a faster rotary movement about its own axis even during the cutting process than when going back.

2. Machine according to claim 1, characterized in that the arm (26) to which its free end the sprocket (32) carries itself during the decline in the same direction, on the other hand during the Cutting gear in the opposite direction as the sprocket rotates, so that in the former case the rotary motion of the Knife is slowed down, in the latter case is accelerated.

3. Machine according to claim 1 and 2, characterized in that the the Knife carrying swing arm (26), the crank (34) and the link (35) are arranged to one another in such a way that the swing arm is in its outermost position when the crank and the connecting link are at dead center so that continued movement of the crank allows the swing arm to fall back so as to cause a rapid retraction of the cutting disc.
