    Apparatus and method for machining the main cut and at least substantially for viscous liberated fish transported with the tail at the front in the transport direction T on a transport section
    Description
    BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device designed and adapted for machining of main cut and at least substantially entrapped fish transported with the tail at the front of the conveying direction T on a conveying line, comprising a conveying means transporting the fish along the conveying section, and a cutting device. for loosening the meat from the flank bones of a fish's skeleton after cutting the abdominal and spinal bones, the cutting device comprising a pair of circular knives rotatably rotatable about a pivot point, which are disposed on opposite sides of the conveying section and are adjustable for position in relation to the fish and thus in relation to the bone skeleton.
    Furthermore, the invention includes a method for machining head-cut and at least substantially entrapped-released fish, in which the tug bones and back bobbins have already been cut, comprising the steps of: transporting the fish with the tail at the front in the conveying direction T by means of a conveying line. conveying means and detaching the meat from the flank legs of the fish's skeleton by means of a cutting device, in which case, on each side of the fish between the flank legs and the meat to be loosened, a rotating circular knife of the cutting device is introduced into the fish in each case. respectively. the middle leg of the bone skeleton. Such devices and methods are used in the fish processing industry to process fish which have already been severed and substantially free of viscera, and where the tug legs and back bobbins have already been cut free. Put another way, the device and method serve to loosen respectively. fresh meat, respectively. more precisely the fillets from the flank bone of the bone skeleton. For this, the rotatable drive circular knives are positioned at a suitable angle to the natural structure of the flanks. Due to the transport of the fish along the transport line on which the round knives lie, the round knives from both sides penetrate the fish, namely between the flank legs and the fillets to be loosened, over the flank legs, so that the fillets are loosened to the main respectively. middle leg.
    As flank legs, such legs are referred to respectively. coil legs surrounding the arch space, respectively. abdominal cavity, respectively. extends arcuate around the abdominal cavity. The flank legs are located at the main and the other. the middle leg of the bone skeleton. Flank legs are predominantly on either side of the head or the other. the middle leg firmly associated with this. In this type of flank bone extends a so-called stem bone, which is firmly connected with the head and the head respectively. middle leg, first cross this, as the stalk goes into a so-called rib. Simply put, a stalk bone and a rib form a solid at the head, respectively. middle leg located flank leg. Such flank bones extending from the region of head and neck respectively. the middle leg, which faces the tail, to the area of the head and. the middle leg facing the head has a slight rounding that corresponds to the rounding of the abdominal cavity, respectively. surrounds this one. The area facing the tail is also called the tail area for simplicity. Similarly, the area facing the head is also called the head area. In the main area of the fish respectively. main and in the middle leg, additional flank legs are located, which are only connected to the head and the head respectively. middle leg with some kind of joint. These flank bones, which occur especially in whitefish species, such as e.g. kabliau, has one in relation to those fixed with the main respectively. the middle leg connected flank legs a stronger rounding, so that because of the upright shape they are also called "spider bones". These strongly rounded or curved flank legs tend to be pushed beyond the cutting edge of the round knives during the loosening process. More precisely, when the fillets are detached from the flank legs by means of the circular knives, there is a risk that the cutting edge of the circular knife cuts the leg arches extending beyond the cutting edge, ie in the work or cutting area, in some fragments, especially in the following (main -) area of the main or middle leg, thereby leaving fragments or residues of the bones in the fillet, which necessitates a further processing of the fillet.To avoid the risk of tearing the flanks, the cutting edge of the circular knives can be started higher, thus, however, the risk of tearing the flanks. Such a cut is undoubtedly leading to a significant reduction in yield as more meat of the fillet including the whole flank bone remains on the bone skeleton, respectively. on main respectively. center pin.
    Such a device with the corresponding method is known in principle, for example, from DE 10 2007 053 905. This document originating from the reviewer's house describes a device with all the characteristics of the preamble of claim 1.
    Accordingly, it is the object of the invention to provide a simple device by which filets can be loosened from the bone skeleton sparingly and efficiently. The purpose also consists in proposing a similar approach.
    This object is accomplished by a device having the characteristics mentioned at the outset in that a circular knife is attached to each round knife which is designed and arranged to hold down at least some of the flanks during the detachment process of the bone from the bone. By means of the additional means attached to each round knife, flank legs projecting into the working knife of the round knife can be used. cutting area, in particular the so-called '' spider bones '', or parts thereof are effectively protected against the rotary cutting edge of the circular knife. Put another way, cutting or tearing off the flanks - at maximum meat yield - is effectively prevented by the loosening process. The pieces of meat obtained by the loosening process, respectively. fillets are in the area of the tail side and especially also in the area of the main side free of fragments of the flanks, so that an expensive after-work can be avoided.
    A particularly preferred embodiment of the invention is characterized in that the means is designed and arranged to actively hold down flank legs located in the main area of the fish and comprises a diverting element located on the upper side of the circular knife facing away from the flank legs. and which is formed and arranged movably from a waiting position which releases the cutting edge of the circular knife to a bypass position which at least partially covers the cutting edge of the circular knife and runs prior to the cutting edge towards the direction of transport T and return. Active describes that the diverting element for holding down the flank legs respectively. pushing them down is movable towards the flanks. In contrast, a passive hold-down motion must be understood without such own diversion movements. By means of the movement of the diverting element and in particular the position of the diverting element in the diverting position, it is ensured that the sharp cutting edge of the circular knife is covered on one side and the flank legs transported by the circular knife are thus protected and the flank legs of the cutting device in the other side of the cutting device are covered. main area is pressed downwards under the cutting edge before hitting the circular knife respectively. its cutting edge.
    Advantageously, the diverting member is disc-shaped and comprises a base member and a diverting member formed integrally with the base member, the diverting member being formed by a detached, finger-like projection oriented towards the conveying direction T. By means of the finger-like projection , which can also protrude beyond the cutting edge's work, respectively. sectional area in a nose or hook-shaped manner against the conveying direction T, it is ensured in a simple and secure manner that the flank legs are in each case pressed downwards before they strike, respectively. enters the work of the circular knife respectively. sectional area. This projection, pointing towards the direction of transport T, has the further advantage that in fish where there is no fixed connection between the meat to be loosened and the flank legs in the main area, since the meat is separated from the flank legs by a kind of membrane, without cutting, but rather by scraping can loosen the meat from the bone skeleton respectively. more accurately from the flank legs. As this kind of release is more product-friendly in terms of cutting, a further improvement in quality is achieved.
    A suitable further development of the invention is characterized in that the plane of the diverting element and the circular knife is parallel to one another and the diverting element is movable relative to the circular knife. This ensures a fast and precise and at the same time stable movement of the diverting element between said positions. Conveniently, the diverting element is pivotal about a pivot point which is outside the pivot point of the circular knife. Thus, with the help of small and. For minor swing movements, a sufficient adjustment of the diverting element between the positions is achieved.
    Advantageously, a pneumatic cylinder unit is attached to the bypass element to exert the pivotal movement about the pivot point. With the pneumatic cylinder unit, a simple as reliable possibility of moving the diverting element has been created.
    A further particularly preferred embodiment of the invention is characterized in that the means is designed and arranged to hold down flank legs located in the main area of the fish and comprises a diverting element disposed on the underside of the round knife facing the flanks, the cutting edge of the circular knife has a larger circumference than the diverting element such that the circular knife with the cutting edge extends beyond the diverting element. This diverting element provided alternatively and preferably cumulatively to the diverting element disposed on the upper side of the circular knife facing away from the flank legs supports the diverting of the flank legs below the cutting edge of the circular knife. This diverting element consequently causes the flank legs to be held down passively, as it stands in the way of the upright and upright respectively. into the working knife of the circular knife. sectional area protruding from the flanks, forcing these to divert downwards below the cutting edge.
    Advantageously, the diverting element has a greater thickness than the circular knife. Thus, it is achieved that the flank legs strike the diverting element as early as possible and are accordingly directed downwards.
    A suitable further development of the invention is characterized in that the diverting element is an integral part of the circular knife so that the diverting element can be rotated about the pivot point together with the circular knife. By forming into one of the circular knife and diverting element, it is ensured that the diverting element is permanently and accurately positioned to keep the flank legs down in the correct position relative to the circular knife. Alternatively, the diverting element may also be formed stationary in relation to the rotary circular separately, so that the circular knife rotates over the diverting element.
    Preferably, the diverting member is plate-shaped and concentrically arranged with the circular knife, a circular, ramp-shaped transition being formed between the circular knife and the diverting element to form a diverting angle a. This ramp-shaped transition rises from the circular knife, respectively. the plane defined by the circular knife radially inwardly towards the diverting element respectively. toward the plane of the diverting element. The term '' plane '' in this context is not a two-dimensional plane in the strict mathematical sense, since the diverting element has a material strength / thickness and consequently many planes, however, all run parallel to each other and also parallel to the circular knife. Due to the radially inward course, the flank legs are reliably controlled under the cutting edge of the circular knife.
    The object is also met by a method of the steps mentioned at the outset in that at least some of the flank legs are pressed downwards by a means for holding the flank legs down during the loosening process for the meat from the bone skeleton. The special feature of the method according to the invention consists in that the flank legs which are in the direction of the head of the head respectively. the middle leg, and especially the so-called '' spider bones '', which would stand upright in particular, crossing the circular knife, respectively. sectional area, is guided below the cutting edge before hitting the cutting edge of the circular knife, thereby protecting all flank legs from damage / tearing. The additional resulting advantages have already been described in connection with the device, so that, in order to avoid repetition, reference is made to the relevant passages.
    Preferably, flank legs located in the main area of the fish are actively directed downwardly below the cutting edge of the circular knife by means of holding down, as a deflection member disposed on the upper side of the circular knife facing away from the flank legs moves from a waiting position which releases the cutting edge of the circular knife. , to a bypass position which at least partially covers the cutting edge of the circular knife and runs prior to the cutting edge towards the direction of transport T and return. In this connection, the return movement back to the waiting position preferably occurs only after complete completion of the loosening process for the fillets from the flanks to prepare the device and especially the cutting device for the next loosening process.
    Advantageously, the diverting element is pivotally controlled by a pivot point which is outside the pivot point of the circular knife. As a result of the clock control, the diverting element is only in the working position when necessary. As a result of the aforementioned displacement of the pivot point, the circular knife is held respectively. the cutting edge by means of simple and short movements of the diverting element for the first sharp and second blunt, according to the condition just needed.
    A preferred further development of the invention is characterized in that flank legs located in the main area of the fish are guided downwards below the cutting edge by means of the holding down, these flank legs, as a result of the transport along the transport section, are diverted downwards by means of a diverting element which is placed on the underside of the circular knife facing the flanks.
    The additional advantages resulting from the process steps of the invention have already been described in connection with the device which is particularly suitable for carrying out the method according to the invention, and therefore the relevant passages are also referred to herein.
    Further advantageous and / or appropriate features and further developments of the invention are set forth in the subclaims and description. Particularly preferred embodiments are explained in more detail with the aid of the attached drawing.

    The invention is described by means of a device for loosening the fillets from the flank legs of whitefish species. However, the invention, of course, relates generally to devices for loosening meat from the flanks of a fish of various fish species. The device according to the invention is shown as a single machine. However, the device is in principle a component of a fish filleting machine.
    The device 10 shown in the drawing is designed and arranged for machining of main cut and at least substantially for viscous liberated fish which are transported with the tail at the front in the direction of transport T on a transport section. By "substantially" it is expressed that the viscera are in principle removed manually or mechanically, but that there may be residues of the viscera and / or blood residues in the abdominal cavity which do not affect the invention. The device 10 comprises a transport means 11 which transports the fish along the transport line, and a cutting device 12 for releasing the meat from the flank legs 13 and 13a of a fish's leg skeleton 14 after cutting the abdominal and spool legs 15, 16. The transport means 11 comprises at least one circulating driven support body. 17. Preferably, several support members 17, also known as transport saddles, are circulating on a chain or the like. The fish rests with the bow downwards and the tail at the front in the transport direction T with its head respectively. the middle legs 18 of the support body 17 so that the flank legs 13 extend obliquely to the side respectively. slightly rounded down. Along the transport line, devices such as machine housings, control and / or drive units or the like for processing units are arranged on a frame or stand. A machining unit is the cutting device 12 comprising a pair of circular knives 19, 20 which can be rotatably rotated about a pivot point D and located on opposite sides of the conveying line and are adjustable by means of the control and / or drive assemblies with respect to position relative to the fish and thus relative to the bone skeleton 14. Optionally, processing units are provided in front of the cutting device 12 for cutting the tug legs and the back bobbins.
    This device 10 is characterized by the invention in that a circular knife 19, 20 is attached to each round knife 19, 22 which is designed and arranged to hold at least some of the flank legs 13a during the detachment process for the meat from the bone skeleton 14. Flank legs 13, which are fixedly connected to the main and the main respectively. the middle leg 18, runs through on the transport section under the circular knives 19, 20 and 20, respectively. their work respectively. sectional area. The flank legs 13a on the side of the fish respectively. the bone skeleton 14 facing away from the tail, that is, at the end of the bone skeleton 14 on the main side, and which is connected only to the head and the tail, respectively. the middle leg 18 via a kind of joint, rises in relation to the firmly connected flank legs 13 and is pressed by means 21, 22 under the circular knives 19, 20 so that the circular knives 19, 20 can completely dislodge the fillets from flank legs 13, 13a.
    The characteristics and further developments described below are seen individually or in combination with preferred embodiments. It is explicitly mentioned that features summarized in the claims and / or description or described in a common embodiment can also functionally independently further develop the device 10 described above.
    Preferably, the member 21,22 is formed and arranged to actively hold down the flank legs 13a located in the main area of the fish and comprises a bypass member 23, 24 disposed on the upper side of the circular knife 19, 20 facing away from the flank legs 13, 13a, and formed and arranged movably from a waiting position releasing the cutting edge 25, 26 of the circular knife 19, 20 (see, for example, Fig. 1), to a bypass position at least partially covering the cutting edge 25, 26 of the circular knife 19, 20 and runs ahead of the cutting edge 25, 26 towards the transport direction T (see, for example, Fig. 5), and returns. The member 21, 22 is referred to as active as it is self and separately movable against the flank legs 13, 13a and movable away from these to hold them down. The bypass element 23, 24 partially covers the circular knives 19, 20 and is disc-shaped. The outer edges of the deflector 23, 24 are blunt. Each diverting member 23, 24 comprises a base member 27, 28 and a diverting member 29, formed in a base body 27, 28. Preferably, the diverting elements 23, 24 are formed in one. However, a design of the diverting elements 23, 24 in several parts is also possible. The diverting body 29, 30 is formed of a finger-like projection 31, 32 released against the basic body 27, 28 which is oriented towards the conveying direction T. In another way, the diverting element 23, 24 has a basic shape which differs from a circular shape with an exemplary V-shape. shaped or U-shaped recess 33, 34. The recess 33, 34 may also have a different shape. Crucial to the shaping of the diverting element 23, 24 parallel to the circular knife 19, 20 is the provision of the protruding and projecting section T, namely the finger-like projection 31, 32, which can preferably be moved over the base body 28, 29 so that the section reaches the flank legs 13a, before the circular knife 19, 20 and 20, respectively. its cutting edge 25, 26 engages the meat respectively. in the flank legs 13a.
    Since both the circular knife 19, 20 and the diverting element 23, 24 are formed disc-like, the said components in each case tension a plane. These planes of circular knife 19, 20 and diverting element 23, 24 for each pairing of circular knife 19 / diverting element 23 and circular knife 20 / diverting element 24 are preferably parallel to each other in each case. The diverting element 23, 24 is movable relative to the circular knife 19, 20, namely that the pivot plane, that is, the plane in which the diverting element 23, 24 is moved, is also parallel to the plane of the circular knife 19, 20 and the diverting element 23, 24. The diverting element 23, 24 is pivotally about a pivot point S, the pivot point S being outside the pivot point of the circular knives 19, 20. the pivot axis perpendicular to the pivot plane also extends outside the circular knives 19, 20, so that a pivot torque arm which is larger, respectively, is formed. longer than the 19, 20 radius of the circular knives. For preferably clockwise triggering of the swing motion, a swing mechanism is associated with each bypass element 23, 24. In the illustrated embodiment, the pivot mechanism comprises a pneumatic cylinder unit 35, 36. However, this can also be supplemented or replaced by other conventional actuation mechanisms. Optionally, restriction means not shown for limiting the pivot path may also be provided. In further embodiments not shown, the circular knife 19, 20 and the diverting element 23, 24 may optionally also be at an angle to each other. The relative movement between circular knives 19, 20 and diverting element 23, 24 may also be realized by a linear motion. In a preferred further development of the invention, the means 21, 22 are designed and arranged to hold down the flank legs 13a located in the main area of the fish and comprise a bypass element 37, 38 disposed on the underside of the circular knife 19, 20 facing the flank legs 13, 13a. The cutting edge 25, 26 of the circular knife 19, 20 has a larger circumference than the diverting element 37, 38 such that the circular knife 19, 20 with the cutting edge 25, 26 extends beyond the diverting element 37, 38. This diverting element 37, 38, which is stationary or rotating with the circular knife 19, 20 is formed disc-like, respectively. plate-shaped and having a thickness which is preferably thicker, respectively. greater than the thickness of the circular knife 19, 20. In a preferred embodiment, the diverting element 37, 38 is an integral component of the circular knife 19, 20, the circular knives 19, 20 and the diverting elements 37, 38 being assembled respectively. connected to one another into a unit into one. This unit can be rotatably rotated about the pivot point D. plate-shaped diverting elements 37, 38 are arranged concentrically with the circular knife 19, 20. By means of the different diameters of circular knife 19, 20 and diverting elements 37, 38, a shoulder is formed, over which preferably a stepless bridge is formed by means of a circulating ramp-shaped transition 39, 40. This transition 39, 40 is made ramp-shaped to form a bypass angle a. Expressed in another way, the transition 39, 40 from the cutting edge 25, 26 increases radially inwardly, the starting point of the transition 39, 40 forming the round knife. 19, 20 projection L1 over the diverting element 37, 38 can be displaced relative to the outer circumference of the cutting edge 25, 26. The size of the angle α is variable and depends on the species of fish to be processed, respectively. of the anatomy of his leg bone 14. It is dependent on preselection between 15Q and 75Q and preferably between 30Q and 60Q. The size of the protrusion LI of the cutting edge 25, 26 against the diverting element 37, 38 is small in comparison with the diameter of the circular knife 19, 20 and the diverting element 37, 38 and is preferably a few mm. Of course, the size of the stretch LI may also be chosen arbitrarily differently. In the following, the method principle of the invention is described by the preferred embodiment, wherein the means 21, 22 comprise both the diverting elements 23, 24 and the diverting elements 37, 38.
    Preferably, the fish are placed manually on the support body 17, namely with the tail at the front in the direction of transport T and the bow downwards, so that the fish with its middle leg 18 rests on the support body 17. Thus oriented, the main cut and at least substantially for viscera-released fish are carried, where the bowling legs. 15 and the spindle legs 16 are already cut free, in the conveying direction T along a conveying line by means of the conveying means 11. Upon passage of the cutting device 12 lying on the conveying leg, the meat is released from the flank legs 13, 13a of the fish's leg 14 by the cutting device 12, on each of both sides of the fish at a suitable angle to the bone skeleton 14 between the flank legs 13, 13a and the meat to be loosened, over each flank legs 13, 13a, in each case, a rotary circular knife 19, 20 of the cutting device 12 is inserted into the the fish to the bone of the bone skeleton 14 respectively. middle legs 18. In this way the two fillets are cut free from the flank legs 13, 13a.
    In order to prevent the flank legs 13, 13a, in particular such flank legs 13a which, because of their rounding, are cut into the cut area of the circular knives 19, 20, according to the invention, at least some of the flank legs 13a are pressed downwards during the loosening process for the meat from bone skeleton 14 by means of means 21, 22 for holding down flank legs 13a. The flank legs 13a are pressed so far down that they are guided under the rotating cutting edge 25, 26 of the circular knives 19, 20.
    To hold respectively. press the flank legs 13a, which in the main region are rounded upwards into the sectional area of the circular knives 19, 20, respectively. Down can happen in different ways. Preferred is a combination of an influence of the respective flank legs 13a with a hold-down and, respectively. diverting force over the circular knife 19, 20 and below the circular knife 19, 20. At the inlet of the fish lying on the supporting body 17, the diverting element 23, 24, which is placed over the circular knives 19, 20, is in a waiting position (see, in particular, Figs. 1 to 4). In this waiting position, the cutting edge 25, 26 of the circular knife 19, 20 on the side facing the bone skeleton 14 is free and detaches the meat from the flank bones 13 located in the tail area. At the further passage of the fish along the transport section - shortly before the fish with its flank legs 13, 13a in the main area reaches the area of the cutting device 12 - the diverting element 23, 24 about the pivot axis S is pivoted so that the diverting element 23, 24 first covers the cutting edge 25, 26 on that side. facing the bone skeleton 14, and secondly with its finger-like projection 31, 32 '' 'runs towards the transport direction T along the flank legs 13, 13a. In that the projection 31, 32 in the deflection position (see in particular Figures 5 to 8) extends beyond the cutting edge 25, 26 towards the direction of transport T, the upright flank legs 13a first strike the projection 31, 32 which forces the flank legs 13a downwards so that they are guided below the cutting edge 25, 26, before it can break the flank legs 13a. If the flank legs 13a are only once below the cutting edge 25, 26, the flank legs 13a are held without exception below the cutting edge 25, 26 outside the sectional area of the circular knives 19, 20. Thus, this withholding movement is effected by means of a hold-down, respectively. diverting force over the circular knife 19, 20. By means of the movement of the projection 31, 32 into the fish towards the direction of transport T, the effect can be obtained that the projection 31,32 with the firm and blunt edge detaches the meat from the bone skeleton 14 and especially from the flank legs 13a. , since in this area of some fish species such as e.g. cabliau, there is no fixed connection between the meat and the flank legs 13, 13a, because in this area the meat and flank legs 13, 13a are separated from each other by a membranous layer.
    Further, a hold-down motion is followed by a hold-down, respectively. diverting force under the circular knives 19, 20, the flank legs 13a being rounded upwardly in the sectional area of the circular knives 19, 20 are pressed downwardly by the diverting element 37, 38, before the flanking legs 13a strike the cutting edge 25, 26. By means of the diverting elements 37, 38 projecting downwards starting from the circular knife 19, 20, there is a kind of '' clearing '' of the sectional area, with the projecting flank legs 13a forcibly directed downwards.
    However, the method can also be practiced only with one of the two diverting elements 23, 24 or 37, 38. The previously described device 10 according to the invention is particularly suitable for carrying out the method.
    The active bypass elements 23, 24 are controlled clockwise, respectively. is pivoted about the pivot point S, namely between the waiting position and the diverting position. Only when approx. two thirds of the bone skeleton 14 have passed the circular knives 19, 20, the diverting elements 23, 24 are pivoted from the waiting position to the diverting position. In order to find the optimal time for swinging in the divert position, the control of the diverting elements 23, 24 can be connected to an overall control which can communicate information e.g. about the size of the fish, about the transport speed and about other parameters that influence the loosening process.
