Description

There is therefore the task of designing the device mentioned at the beginning in such a way that the meat

can be removed from the bone as completely as possible without damage, without bone loss or fragments of bone develop and remain in the meat.

The invention relates to a device for removing of bones from pieces of meat with elastic according to the provision that the Trenneiemente to braids resting on the bone and encircling it and engaging with the bones Separating elements, wherein between bones and surfaces are formed blunt.

In this device, the separating elements, which can elastically adapt to the cross-sectional shape of the bone as it revolves around it and at the same time are moved in the longitudinal direction of the bone relative to the latter, have a blunt area which engages with the bone to be removed. This design of the device enables the meat to be peeled off from the bone by the blunt separating elements instead of scraping or cutting it off, as has been customary up to now. Characterized that a plurality of elastically pressed against the bone separating elements during their I mlaufs gelaugen rcnnbereich around the bone to act on the 1 between the bone and the JE "cils foremost meat ring of the piece of meat, the Heish is peeled from the bone or peeled off without Remnants of meat remain on the bone and one that the detached meat has bone parts in the form of bone abrasion, bone splinters or the like.

An advantageous embodiment of the invention is characterized in that the separating elements in Are arranged in the form of a diaphragm. This increases the adaptability of the elastically arranged Separation elements are still increased, resulting in a complete adaptation of those formed by the separation elements opening to the respective cross-sectional shape of the

The design of the separating elements is advantageously such that the separating elements have, on the side facing the inner bone, a slot provided for the ^{lower part and the tendons, fle} . ^{r Ul} "· '

The motor 98 can ben ak the drive belt 158, so that the inner ring can be provided with a switching device which is used to reverse the direction of rotation of the drive to a greater extent than the outer ring, so that it revolves at speed. The direction of rotation of the nut 71 and coupling 152 can in this way be reversed in the end position with the direction of the longitudinal movement of the support arm of the separating elements 74 when they are reversed with the 58 relative to the base housing 54.

Opposite is the ring 108, the direction of the relative rotation of the ring Wl is counterclockwise (FIG. 4). As a result, the separating elements 74 together with the levers 76 are pulled into the middle area within the rings W1, 108, and in this way the separating elements come to rest on the bone 94. Since there is now no further relative rotation of the rings 1§7, ItS is more possible, the slip clutch 152 now allows a relative rotation between the shafts 116 and 116α (FIG. 7), so that the inner ring 107 rotates in this position at the same speed as the outer ring 108. This acts on the inner ring 107 a torque which produces a pressing force on the separating elements 74 when they engage with the bone 94. The effect of the separating elements 94 rotating around the bone 94 under elastic pressure is such that the bone 94 is always centered within the ring formed by the separating elements 94. The centering is greatly promoted by the fact that the bone 94 is suspended so that it can swing.

In this way, the bones surrounding and facing the bones under elastic pressure follow Separating elements also moved in the longitudinal direction elements 74 of a helical path on the circumferential surface of the bone, the separating elements 74 depending on the bone cross-sectional profile with which they are currently come into engagement, relative to the longitudinal center axis of the rings 107,108 more or less far from -45 soft, so that under all circumstances the engagement between the separating elements 74 and the bone 94 is retained. Because a constant pressing force is also achieved due to the constant torque is and the separating elements 74 only with their 5 ° blunt area 75 in engagement with the bone come, they loosen the flesh from the bone that is doing it is pushed away from the bone, peeled off or peeled off without damaging the bone. 9 illustrates a location of the bracket 82 55 compared to the stripping device 56 during the is the processing, while Fig. 10 illustrates an in which a considerable part of the meat 93 has already been detached from the bone 94 is and the stripping device 56 is consequently 6 ° already a considerable distance from the support arm Has reached 50.
