Device for skinning fish fillets

The invention relates to a device for skinning fish fillets with a pair of the Skin-transporting rollers and one brought into intersection by the fish fillet Skinning knife,

A device is known in which the boned fish fillets by means of pines Pair of rollers pulled past a stationary knife attacking between the fish meat and the skin are and the skin cutting knife via a gear with the control member in such a way is connected that the control member of the leading end of the fish fillet directly is moved after passing the attack point of the Hessers and via the gearbox that Hesser, which is initially in an inoperative position, moves into the cutting position. It is also a method and apparatus for mechanically skinning fish fillets known to have a «pair of rollers grasping the farthest end of the fish fillet, one? Skinned tea eater and a mechanism for moving the skinning knife substantially perpendicular to , and so close to the transporting surface that the distance between the cutting edge of the skinning eater » of this is approximately equal to the skin thickness and for the subsequent pivoting of the same into a shallower slope for cutting between meat and skin. In both devices, the skinning knife is driven by the skinning rollers in the drive when the end of the fillet enters its feed gap, there is resistance in the cutting position and the resistance caused by the leg clamping of the skin between the rollers Drive held in the cutting position. This must be done by the respectively arranged Zuafeder generated Rückstellmcment be overcome. For small fish fillets with thin skin oriql, the resistance that occurs when clamping between the rollers is sufficient after switching on not enough to maintain a moment sufficient to overcome the spring force, so that the skinning itself during the skinning process, but at least before its Feendiqimq,

stands out from the transporting surface.

or at least be severely frayed. ". '

The purpose of the invention is to skin small and / or thin-skinned fish fillets » The technical task is to create a skinning machine for fish fillets,

by which small and thin-skinned fish fillets are not eaten. ■

The invention relates to a device for skinning fish fillets mit.einem Pair of rollers rotating in opposite directions, one swiveling against one of the rollers

inesser and a control device, which the skinning knife by the inlet of the

Fillet end in the nip of the roller pair in 'its drive occurring resistance

turns on, which is characterized in that the skinning knife after Bring, in

Cutting position is kept locked in this until the skinning process is finished. . · The effect of locking the skinning knife after it has been brought into cutting

Position according to the invention is so striking that it is possible to skin thin-skinned and small fish fillets without the fish fillets fraying or being eaten up.

Locking can be achieved in a number of ways. For example, according to claim 2, a holding magnet can be arranged on the skinning knife itself, on the mechanism controlling the skinning knife or the mechanism triggering the control, but you can also generate the cutting pressure acting on the cutting edge of the skinning knife around its Hesserträqer 'H Use moment to lock by using the control for the skinning knife, qemä8 claim 5, not positively but non-positively, whereby then - qemä8 claim 6, the tension spring is to be dimensioned accordingly. The holding magnet can, according to claim 3, be actuated by a button reaching into the path of the fish, it can be switched on, according to claim k, but also by a member that brings the skinning knife into the cutting position, and can be switched off by a button.

The invention is shown schematically in drawings and will be described on the basis of these,

■ Fig. 1 shows a device according to claim 3 before switching on,

Fig. 2 shows the same device after the finschal th,. Fig. 3 'shows the electrical-Iiechanische scheme for the same device. Fig. K shows a device according to claim 5.

On the loading side is the feed belt 1, which runs in the direction of the arrow. Behind the infeed belt, the skinning roller 3 runs around a machine-fixed axis. arranges, which is the opposite with the same circumferential speed rotating pinch roller-5 assigned. The high-speed transfer roller is located between the skinning roller and the feed belt 2 arranged. In bearings fixed to the machine, the one carrying the skinning knife 10 is Water carrier 11 stored, which at least at one end has a pivot lever 1? träqt. In the device according to Figs. 1 to 3, the clamping roller 5 is in the and the M'se der EnthXutevalz 3 pivotable swivel arms 6 mounted, which by the spring 7, against the ' Stop 8 must be held in the starting position. Such a 9 is located above the stop 8 provided as a limit for the deflection of the swivel arm 6 upwards, the animal drive Pinch roller 5 takes place through skinning roller 3.

In front of the draw-in wedge between the rollers 3 and 5 there is a button 14 which a tension spring 15 resting against the stop 16 just above the dumbbell of the skin roller 3 is held. In addition to the spring 7, the core of the holding magnet 19, which is fixed to the machine, is connected to the Pivoting »6 connected. In addition to the stop 9, the working contact 18 is located in the cock of the upper lever frame of the button 14 of the normally open contact 17 with the interposition of a not illustrated compression spring acted upon by this. ■ The mode of action is as follows: '

The tail tip of the feeder belt 1 fed in front with its skin soap below fish fillets lying down, runs over the transfer roller 2 carried by the skinning roller 3 and taken into the gap between rollers 3 and 5. Pure enema of the fillet top in this gap the Schwenkarn 6 is pivoted counterclockwise, takes the Pinch roller doesn’t and, by actuating the pivot lever 12, brings about the cutting process

of the skinning eater 10..

Here, the working contact 1fl is closed. Oa previously the work contact 17 was already closed by lifting the 4ns button, the winding of the holding magnet 19 is traversed by current and holds the swivel arm 6 against the stop 9 until the outgoing filleting - lets the button H fall again, thereby opening the Arheitkontaktaki 17 again the winding of the holding magnet 19 has become de-energized and causes it to fall off, the oil device according to Fig. k differs from the previous one in that the pinch roller 5 is also fixed to the machine, underneath it is a pinion wheel, which is also fixed to the machine and can be moved between these, mounted on the switching rocker 13, the ratchet wheel k is arranged »the rocker arm 13 is pushed by the spring 7 against the stop. 8 held. "The pivoting lever 12 carried by the knife carrier 11, which is fixedly mounted on the machine, is held against the uppermost part of the switching rocker 13 by the tension spring 20. When the leading tail of the fish fillet enters between the rollers 3 and 5, the switching rocker 13 is pivoted clockwise and brings the skinning knife into cut position .- · "-.:*_-
