Definitions

  • a bacon derinding machine comprises a knife which is preferably adjustable to different derinding thicknesses and to total derinding of a material to be derinded; a traction roller for conveying the material up to said knife, the arrangement being such that a gap is left between the cutting edge of the knife and the traction roller, and a feed table having a supporting surface which is generally on a level somewhat lower than that of the gap between said cutting edge and said traction roller, the supporting surface of the feed table having within range of its end extending up to a position close to the cutting edge of the knife an end section which extends upwardly and away from the traction roller.
  • This invention relates generally to bacon derinding machines with a knife, a traction roller for carrying the material to be derinded onto the knife, and a feed table having a supporting surfaces which is generally on a level somewhat lower than the gap between the cutting edge of the knife and the traction roller, the material to be derinded being brought within range of the traction roller on the said supporting surface and the knife of the bacon derinding machine being preferably adjustable to different derinding thicknesses or to total derinding.
  • the supporting surface of the feed table is plane and substantially horizontal; in front of the traction roller it terminates at a slightly lower level than the edge of the derinding knife thus leaving, between the edge of the supporting surface adjacent to the traction roller and the knife edge, a zone along the traction roller, the size of which is in the region of 30 mm measured in the peripheral direction of the traction roller.
  • the areas of the ball of the thumb of the op erator are particularly endangered.
  • the operator may e.g., feed a piece of bacon which is to be derinded to the traction roller or the drinding knife while at the same time pressing it onto the supporting surface of the feed table, and at the same time introduce the lateral edges of the ball of the thumb within range of the traction roller directly in front of the edge of the derinding knife, e.g., owing to lack of concentration but possibly also because of unfortunate circumstances, so that the traction roller grips parts of the hand drawing them over the derinding knife, which may give rise to considerable injuries.
  • the object of the invention to provide a machine for derinding pieces of bacon, meat or other material to be derinded, in which, on the one hand, the risk of accidents is considerable reduced, while, on the other hand, the operation of the above-mentioned bacon derinding machine undergoes no impairment or no significant impairment.
  • the latter should apply also to derinding of partly dried bacon, total derinding and bacon derinding machines or the like, in which the knife can be adjusted to different derinding thicknesses.
  • a bacon derinding machine which comprises a derinding knife with a cutting edge and preferably arranged to be adjustable to different derinding thicknesses and to total derinding of a material to be derinded; a traction roller for conveying said material up to said knife, the arrangement being such that a gap is left between said cutting edge and said traction roller, and a feed table having a supporting surface on which the said material is conveyed within range of the traction roller, and which is generally on a level somewhat lower than that of the gap between said cutting edge and said traction roller, said supporting surface of the feed table having within range of its end extending up to a position close to the cutting edge of the knife an end section which extends upwardly and away from the traction roller.
  • the end section pointing upward and away from the traction roller and hence also from the knife greatly favours the situation, in which the hand or the hands of an operator, if they slip from the piece of baconwithin range of the traction roller and carry out a movement not desired by the operator, is or are led from this part of the feed table over the traction roller.
  • the end of the supporting surface at least if the knife is in its operating position for derinding, may preferably reach at least to about the level of the cutting edge of the derinding knife and may advantageously reach somewhat beyond this level.
  • a specially advantageous further development consists in the fact that the supporting surface viewed in the direction in which the material to be derinded is fed has a slanting portion shortly before its end facing the traction roller, and an end section located in an approximately tangential direction in relation to the traction roller joins the said slanting portion, said end section being at a small distance from the traction roller and leaving only a small gap between its free edge and the cutting edge of the knife.
  • an end region of the stopping face is brought about which is relatively wide viewed in the direction in which the material to be derinded is fed and which has an end zone pointing upward and away from the knife edge. This is well suited to lift a slipping hand over the free zone of the traction roller and possibly also over the edge of the knife so that injuries can be avoided, at least to a large extent.
  • FIG. I is a partial side view of a bacon derinding machine in the region of the knife, the traction roller and the feed table;
  • FIG. 2 is a plan view thereof
  • FIG. 3a is a side view, on an enlarged scale, ofa detail of FIG. 3;
  • FIG. 4 is a partial side view of a somewhat modified design of the feed table
  • FIG. 5 is a plan view of FIG. 4, and
  • FIG. 6 is a side view, on an enlarged scale, of a detail of FIG. 4.
  • FIGS. 1 to 3a show a machine for the removal of rind, skin or the like from pieces of bacon, meat or the like
  • FIG. 3 shows by dash and dot lines the knife 4 and its cutting edge 6 in positions 4' and 6' slightly further away from the traction roller 3. Hence, the cutting edge 6 can pass through different positions, between a lower position shown by full lines in FIG. 3 and the position 6' shown by dash and dot lines, and it may possibly go even beyond this position 6'.
  • a feed table 9 Mounted on the side of the feed roller 3 from which the material to be derinded is fed, is a feed table 9 carrying a supporting surface 8 which has a somewhat slanting portion 10 within the area of its ends facing the traction roller 3, which slanting portion 10 is followed in the direction of feed by an end section 11 located in approximately tangential direction in relation to the traction roller 3.
  • the end section 11 is at a small distance from the traction roller 3 and reaches so far that only a relatively small gap Sp remains between its free edge 12 and the cutting edge 6 of the knife 4.
  • a length l of the end section 11 amounting to about 20 to 28 and preferably about 24 mm has proved advantageous.
  • the gap Sp between the free edge 12 of the end section 11 and the cutting edge 6 of the knife 4 should amount in the normal derinding position of the knife 4 to about 12 to 18 mm. With the above design narrowing of the gap Sp is possible to about half the gap width hitherto usual in the case of machines with flat feed table supporting surfaces, without any practically noticeable impairment of the operation of the bacon derinding machine 1.
  • the knife 4 is shown by full lines in the normal derinding position, i.e., in its lower position. In this position of the knife 4, the free edge 12 of the end section 11 of the supporting surface 8 reaches slightly above the level of the cutting edge 6 of the knife 4, i.e., by the distance h, e.g., approximately 1 millimetre.
  • FIG. 3 also shows that in the upper position 6' of the cutting edge 6, e.g., with total derinding, a very high degree of protection is likewise achieved. Since the free edge 12 of the edge section 11 of the supporting surface 8 and the cutting edge 6 in its position 6' are close to one another, the gap between the cutting edge 6 and the free edge 12 of the end section 11 is so narrow that it is no longer possible to insert ones fingers into the range of the traction roller 3.
  • the cutting edge 6 is in an intermediate position between its lower position and position 6, it is at a lower level than the free edge 12, whereby however the gap between the cutting edge 6 and the free edge 12 is enlarged. Owing to the lower position of the cutting edge 6 and because of the angle of rise a of the end section 11 amounting to about 30 (FIG. 1) a high degree of protection is ensured also in that case.
  • a bacon derinding machine 1a is provided with a supporting surface 18 of which the end section Ila near the traction roller 3 and at a short distance therefrom is slightly bent upwards, whereupon it continues in the form of a zone 22 brought up to the traction roller 3 approximately horizontally or parallel to the direction of the portion 18a of the supporting surface 18 which is remote from the traction roller 3, as can be seen particularly clearly from FIG. 6. Also in this case it is brought about by the design of the end section 11a which is directed upwards and away from the traction roller that slipping hands, the movement of which is momentarily not controlled by the operator, are guided away from the traction roller 3 and the derinding knife 4.
  • the approximately horizontal zone (FIG.
  • a bacon derinding machine comprising a. a derinding knife with a cutting edge and preferably arranged to be adjustable to different derinding thicknesses and to total derinding of a material to be derinded;
  • a traction roller for conveying said material up to said knife, the arrangement being such that a gap is left between said cutting edge and said traction roller, and
  • a feed table having a supporting surface on which the said material is conveyed within range of 'the traction roller, and which is generally on a level somewhat lower than that of the gap between said cutting edge and said traction roller, said supporting surface of the feed table having within range of its end extending up to a position close to the cutting edge of the knife an end section which extends upwardly and away from the traction roller.
