The invention relates to a device for skinning fish fillets, in which the pivotable The skinning knife is swiveled against the fillet, which is lying with the skin side on the skinning roller when the fillet end enters the gap between the skinning roller and the pressure roller the tooth pressure in the roller gear is increased, and the purpose of the operation of the device to be improved by the fact that a considerably higher switching speed for switching on the skinning knife is available.

Devices of the type described are known and work normally so that the increased tooth pressure the pivoting of a gear causes the in one under the action of a return spring standing shift rocker is mounted, wherein the gear causing the shift on the pressure roller lies. But this has the disadvantage that the switching speed is relatively low, so that the Skinning knife is only moved slowly into the fish meat and only long after it has entered the fish of the fish in the gap between the skinning roller and pressure roller begins to skinning, so that the proportion of valuable fish meat leaving the skin at the end of the tail is very large.

It has now been found that this disadvantage can be eliminated in a simple manner if one the ratchet in the drive gear of the skinning roller in front of the gear connected to the pressure roller arranges. This ensures that the skinning knife immediately after the fish has entered into the gap between the skinning roller and pressure roller with high switching speed into the fish penetrates and gets into its working position. The rapid onset of the knife cut has the consequence that on the skin at the tail end only a negligibly small part of fish meat remains as waste.

The inventive design of the skinning device, d. H. thus relieving the pressure roller from the switching process, there is also the possibility of To arrange the skinning roller and pressure roller stationary to one another, creating an absolutely exact Guidance of the fillets during the skinning is guaranteed.

If the knife carrier is pivoted in pendulum arms, which in turn pivot around fixed bearing points are suspended, the rocker arm advantageously engages via a double lever on the axis of the Knife carrier to rotate it to pivot the knife from the rest position into the cutting position and back, and there are two stops opposite one another on a bow arm of the rocker arm Device for skinning fish fillets

arranged, which in the further movement of the rocker arm after rotation of the knife carrier axis these to advance the knife into the working position and to retract the knife take with you to the starting position.

In the drawings, an embodiment of the invention is shown schematically; it shows

F i g. 1 the control kinematics of the knife,

Fig. 2 is an elevation of the device from FIG Working side.

In Fig. 1 shows the movement of the cutting edge of the skinning knife α , indicated by dashed lines, in a four cycle in the form of a square 1, 2, 3, 4, with the four cycles with 1-2, 2-3, 3-4 and 4-1. The circles shown in solid lines in FIG. 1 denote the skinning roller b ' and the pressure roller c', while in FIG. 2 the roller gear drive driving these rollers is shown. The closer details about the processes in the individual clocks emerge from a consideration of FIG. 2.

The skinning roller b ' receives its drive via the gears b, c, d and e, of which the wheel d represents the ratchet wheel, which is mounted in a switch rocker g that can pivot about the bearing point /. A bow arm h is attached to the rocker arm g , one end of which carries a double-jointed lever i, i with the pivot axes u and ν , which engages the axis w of the knife carrier k , while the other end of the bow arm h carries an adjustable stop Z. There is also an adjustable stop m on the part of the bow arm h that supports the double joint lever /, i . The knife carrier k is pivotably mounted in pendulum arms η , which in turn are suspended pivotably about fixed bearing points ο and are limited in their pivoting movement by adjustable stops r and 5 . The rocker arm g is under the action of a return spring t.

The mode of operation of the device is as follows: When a resistance occurs in the transmission, the wheel d shifts to the right between the wheels c and e , thereby pivoting the shift rocker g. This means that the arch

arm h and the double joint lever i, i the knife carrier k with the knife pivoted about its axis w , with which the cycle 1-2 is carried out. At the end of cycle 1-2, the stop I strikes against the knife carrier k and pushes the entire knife carrier with the knife in a small arc to the right. At the end of this shift, cycle 2-3 is ended and the knife is in the working position. This position of the parts is shown in the drawing, since the pendulum arms η rest with their free end on the stops r .

If the skinning work is finished and the resistance in the gear stops, then the return spring t pulls the rocker arm g back into its starting position, whereby first the bow arm h via the double joint lever i, i the knife carrier k and thus the knife about the axis w in the reverse Swiveled direction until the knife carrier k meets the stop m of the bow arm h coming towards it. This ends cycle 3-4, and cycle 4-1 now takes place, since the stop m now moves the knife carrier k to the left. As soon as the pendulum arms hit the stop, cycle 4-1 is ended and the knife is back in its original position.

Claims (3)

Patent claims: 1. Device for skinning fish fillets, in which the pivotably mounted skinning knife is pivoted against the fillet lying with the skin side on the skinning roller, when the tooth pressure in the roller gear is increased by running the fillet end into the gap between the skinning roller and the pressure roller increased tooth pressure causes the pivoting of a ratchet wheel, which is mounted in a rocker arm under the action of a return spring, characterized in that the ratchet wheel (d) in the drive gear (e, d, c, b) of the skinning roller (&') in front of the the pressure roller (c ') connected gear (c) is arranged. 2. Apparatus according to claim 1, characterized in that the skinning roller (& ') and the Pressure roller (c ') are fixedly mounted to one another. 3. Apparatus according to claim 1 or 2, in which the knife carrier is pivotably mounted in pendulum arms, which in turn are suspended pivotably about fixed bearing points, characterized in that the rocker arm (g) via a double joint lever (i, i) on the axis (w ) of the knife carrier (k) engages in order to pivot the knife from the rest position into the cutting position and back, and that on a bow arm Qi) the rocker arm (g) opposite each other two stops (I, m) are arranged, which in the Further movement of the switching rocker (g) after the knife carrier axis (w) has been rotated, take it with you to advance the knife into the working position and to retract the knife into the starting position.
