    in DK 2012 00080 U4 D-cut cutting apparatus
    FIELD OF THE INVENTION
    The present invention relates to a cutting apparatus of the kind used for cutting especially fish fillets and a set of knives for use in such cutting apparatus, and further to a method of cutting fish using both an apparatus and a set of knives according to the present invention. .
    BACKGROUND OF THE INVENTION
    Within the area, a number of different cutting devices of the type mentioned above are known. Manufacturers of such cutting machines are CP Food Machinery, GEBA Maschinentechnik, and others. Common to all of these known apparatus is the fact that the fillet to be processed is placed on a conveyor which will pass the fish fillet past a cutting arrangement where the fish fillet is cut according to predetermined parameters. As the fillet passes through the cutting arrangement, the cutouts will be more or less preserved in the shape of the original fish fillet and eventually transferred to a plate, typically a piece of cardboard covered with a silver or gold-like surface treatment. After that, the sliced fillet is vacuum packed and sold for consumption.
    Although a wide variety of meat products can be used with the cutting apparatus described above, they find widespread use when cutting fish fillets, and especially salmon and halibut fillets, which may have been pre-processed prior to the cutting process.
    A common problem with the known machines is that the working speed has been relatively low and that the cutter bar was exposed to deflection. When relatively wide fillets were cut, or in structures where two conveyor systems were arranged in parallel, two fillets had to be cut at the same time and the cutter bar was bent, whereby the cutting quality and the thickness of the cut varied. This, in turn, led to a decline in the quality of the finished product.
    2 DK 2012 00080 U4
    In addition, to be able to cut fish products quickly enough, a set of reciprocating blades is forced which is forced through the fillet meat towards a cutting table. The cutting table is typically a plastic structure in which a groove is formed such that when the knife passes through the fish meat it will be able to penetrate slightly into the cutting table due to the presence of the groove. When the angle between the cutting plane of the knife and the table is initially adjusted, a zero point is created. This zero point is the optimal position / angle of the blades relative to the cutting table, where the blades of the cutting device are closest to the cutting table, so that a clear, clean and finished cut can be obtained during production. However, during the process of cutting fillets, it is desirable to be able to change the cutting angle. When the cutting angle is changed, the ratio of the cutting table to the blades also changes, making the zero point no longer achievable, thereby achieving a poorer cutting result.
    In order to optimize the result of the individual fillet, it is desirable to be able to change the cutting angle during cutting of a single fillet, and it has therefore been customary to adjust the zero point so that most of the cut pieces, typically cuts in a center area of the fish fillet, have optimal cutting conditions.
    Objects of the Invention
    It is therefore an object of the present invention to increase the cutting quality, improve the hygienic conditions around the machine and provide increased performance without impairing the quality of the product.
    Description of the Invention
    It is achieved by a cutting apparatus of the kind used to cut especially fish fillets, the apparatus comprising a conveying path and cutting means arranged in the conveying path, the cutting means comprising a set of movable reciprocating knives and a cutting table, the cutting means further comprising means for moving the blades in relative to the cutting table and the surface of the conveying web, wherein the cutting means are arranged on a common element rotatable through a predetermined arc about a horizontal axis and perpendicular to the conveying path of the conveying path.
    With this inventive construction, both the knives and the cutting table are arranged on a common element, which will typically take the form of a relatively large disc, such that as the angle of the blades changes, the cutting table will be rotated to exactly the same when turning the disc. manner. In this way, the zero point is preserved, ie. the optimum cutting point between the blades and the cutting table, regardless of the cutting angle between the blades and the fish fillet located on the transport path. The predetermined arc will be discussed in more detail below, but typically the rotation of the common element should be allowed to be such that any desired cutting angle, ie. the angle between the plane of the blades and the surface of the conveying path can be obtained.
    In a further advantageous embodiment, the conveying path is substantially linear and the web comprises first, second and third separate conveyors arranged end to end, and the cutting means are arranged between the second and third conveyors seen in the direction of movement of the conveying path.
    The reason for providing first, second and third separate conveyors is that different conditions are present along the conveyor path. On the first conveyor, the surface of the conveyor must be such that it is suitable for receiving the fish fillets as they are transferred either manually or automatically to the cutting apparatus.
    The second separate conveyor usually comprises means for increasing the friction between the fish fillet and the conveyor, the second conveyor pushing the fish fillet through the cutting means and as such being able to interact firmly with substantially the entire surface of the fish fillet which is in contact with the conveyor and be able to advance the fish fillet through the cutting means so that the desired cutting operation can be performed. The surface of the conveyor belt will typically be provided with small spikes which will be introduced into the fish meat as the fish fillet is transferred from the first conveyor to the second conveyor. By having a significant amount of spikes distributed in the surface of the other conveyor, a relatively firm connection is created between the fish fillet and the conveyor, thereby minimizing any distortion that could occur due to the cutting means' engagement with a fish fillet.
    4 DK 2012 00080 U4
    The third conveyor is suitable for receiving the cut fish fillet and transferring the fish fillet for further handling, e.g. on a cardboard blank, which is then packed for transport, etc.
    In a still further advantageous embodiment of the invention, means are provided perpendicular to the thickness of the conveyor path to record the thickness of a fish fillet conveyed on the first conveyor and these means provide input to the cutting means.
    By recording the thickness of the fish fillet, it is possible, by angling the cutting means as described above, to achieve that the finished fish fillets have a desired size. For example, by tilting the cutting means such that the cutting angle relative to the surface of the conveying web is relatively flat, relatively large cut pieces can be obtained.
    In the art, cutting apparatus to which the present invention is directed is also known as D-cut cutting apparatus, in that the side of the fish fillet facing the conveyor belt will typically be relatively linear, while the upwardly facing surface of the fish fillet will be slightly round as the round part of a D. By cutting the fish fillet into pieces as described above, the individual cut or piece will therefore have a D-shape.
    The thickness of the fish fillet determines the optimal distribution in terms of area, cutting angle and cut thickness and is therefore an important parameter in deciding how to cut the fish fillets. For example, when salmon fillets are to be processed, they will typically have a more or less standardized size, since most salmon are raised under conditions similar to use, such that length, width, etc. will be more or less constant. By further determining the thickness of the fish fillet, it is possible to very accurately cut pieces which will have a predetermined weight or predetermined size.
    In an even further advantageous embodiment, the means for moving the blades relative to the cutting table comprises active movable guide means arranged at both ends of the blades, where the active guide means are coupled to a common actuator.
    One of the problems with the known apparatus was that when cutting thick, very solid or slightly frozen fish fillets, it happened that the beam on which the blades were placed bends when the blades engage the fish fillet. Therefore, the resulting cut of the fish fillet would not be very accurate and the overall quality would leave something to be desired. In order to avoid bending the blades, the present invention has provided active movable guide members at both ends of the blades such that the risk of the blades being deflected is much less. The fact that the guide members are active, which in this context is understood as being capable of transferring forces to the blades, as such allows the transfer of forces to the blades at both ends of the blades, such that a significantly greater amount of force can be applied to the blades without bending.
    Furthermore, by connecting the active movable guide members at both ends of the blades to a common actuator, a completely homogeneous movement of the blades relative to the cutting table is achieved. In this way, a completely straight and uniform cut will be obtained with the blades along the entire cutting egg, since the guide means at each end of the blades will perform exactly the same relative movement. In the description below regarding a particular embodiment, this movement will be further explained.
    In yet another advantageous embodiment, one, two or more conveying paths are arranged in parallel and the cutting means extend over all the conveying paths.
    As most of the fish fillets as described above will have a more or less uniform size, it is possible to arrange several parallel transport paths side by side so that the apparatus can cut two, three or more pieces in one movement, depending on the number of parallel arranged transport lanes. Particularly in the embodiment where active movable guide members are arranged at both ends of the blades as already described above, the forces created, with relatively long blades spanning two or three conveyor paths, will be substantially reduced due to the 6 DK 2012 00080 U4 active guide members at each end of the blades. Therefore, it is possible to maintain a high production speed with a high quality even when several transport lanes are arranged in parallel.
    In an even further advantageous embodiment, a computer-based system is preprogrammed with information relating to theoretical data on fish fillets, where input means are available, so that an operator can select a first, second and / or third fixed parameter, after which the computer responds to it. Inputs received from the thickness sensing means control the cutting means so that the desired cut of the fish fillet occurs.
    As already mentioned above, fish fillets can have a substantially uniform size at least for batch processing, so that when storing information regarding typical weight, length and width, it is possible to program the machine with very little input to reach the optimal cutting process.
    As an example, the length of the fillet can be divided into e.g. three distinct sections, one tail section, one center section and one front section where the cutting parameters may be different. It can for example. may be desirable to cut thinner pieces in tail sections and anterior sections and relatively thicker pieces in the middle section, and to obtain substantially equal pieces in all sections, the cutting angle may be different from tail section to middle section, the tail section usually being relatively thinner, i. the height between the surface of the conveyor belt and the top of the fillet is smaller in the tail section than it is in the center section. Any of these values can be inputs, or just a few of them, e.g. the desired cut thickness. If the input is the desired cut thickness, the computer will use this input in connection with already stored inputs regarding the type of fish, the size of fish fillets, etc., thus generating the other necessary parameters to obtain a cut as desired.
    In yet another advantageous embodiment, instead of the thickness detection means or in addition to the thickness detection means, a vision system is arranged upstream of the cutting means, the vision system detecting any of the following characteristics of the fish fillet: size, circumference, thickness, color, fat, irregularities, where these characteristics are optionally combined are inputs to the computer based system which produces the control of the cutting means.
    The vision system is typically connected to the computer such that, based on recorded characteristics of a fish fillet passing the vision system, an appropriate set of preprogrammed data related to input from the vision system can be selected such that individual cutting parameters for exactly this particular fish fillet passing the vision system, can be communicated to the cutting means. In this way it becomes possible to cut fish fillets of different sizes and even of different species at random. It is well known in the art that the fish meat and thus the species can be determined by the color and density of the fish meat, so that by programming the vision system in a similar way these types of characteristics can also be determined. Furthermore, the vision system is connected to a control system such that irregularities, high fat content or color variations are detected at this stage and that the fish fillet containing such trigger points can be filtered off and moved to another location. The vision system can, of course, be simply programmed to detect the thickness and / or color of the fish fillet passing under the vision system to control the cutting means to optimize the cutting process.
    In more advanced systems and also in systems where the fish fillets have greater variation in species, size, weight, etc., the vision system is programmed in a more advanced way.
    In a further advantageous embodiment, the reciprocating set of knives comprises two mirrored knives, each knife having a first end and a second end, and a cutting egg along an edge at a predominant portion of the length between the first and second ends where means are provided for. releasably attaching the blades to a reciprocating holder, the means at the first end comprising a pin arranged adjacent the end and perpendicular to the plane of the knife, the pin extending between 5 mm and 30 mm, preferably between 10 mm and 15 mm from the blade blade, and the member at the other end comprising a flat section where the edges are blunt.
    It is known in the art to use reciprocating blades for cutting apparatus of this type. However, a known problem here is that as the production increases, they wear out fairly quickly. Especially when used to cut hard or semi-hard items such as e.g. partially or completely frozen fillets, the wear on the blades is relatively large.
    Furthermore, the blades must be in a state where they are very sharp, especially when cutting tail sections of e.g. Salmon or skin, where the fish skin is left on the fillets, requires very sharp knives. This is due to the fact that the tail section of a fish fillet usually includes tendons and nerves, which makes it relatively more difficult to cut these sections than, for example, the middle section, where most tendons and nerves have been removed during the boning and filleting process. Also, for hygienic reasons, it is very important to be able to remove the blades very quickly so that a thorough cleaning of the apparatus can be achieved.
    With the inventive method of mounting the blades in the reciprocating holder by inserting a pin into a preformed hole and holding the opposite end of the knife loose, but guiding this end very precisely, it is possible to replace the blades very quickly so that production stops can be kept at a minimum.
    In a further advantageous embodiment of the invention, the common element on which the cutting means is arranged rotates through a predetermined arc about a horizontal axis and perpendicular to the conveying direction of the conveying path, where the arc changes the cutting angle from 5 ° to 90 °, more preferably from 7 ° to 75 °, and most preferably from 10 ° to 35 ° relative to the plane of the conveying surface of the conveying path.
    Since the rotation of the common element determines the cutting angle, it is important that the arc through which the common element is allowed to rotate take care of all desirable cutting angles.
    The invention is also directed to a set of knives for use in a cutting apparatus as described above, where the advantages of the knife set are to be found especially in the fact that each knife has a first end and a second end as well as a cutting egg along an edge of a predominant part. of the length between the first and second ends where there are means for releasably attaching the blades to a reciprocating holder, the means of the first end comprising a pin arranged adjacent the end and perpendicular to the plane of the knife where the pin extends between 5 mm and 30 mm, preferably between 10 mm and 15 mm from the blade of the knife, and the member at the other end comprising a flat section where the edges are blunt.
    The inventive apparatus as well as the knife set are particularly useful in a method of cutting fish fillets in a cutting apparatus as described above, wherein the apparatus comprises a conveying path and cutting means arranged in the conveying path, the cutting means comprising a set of movable reciprocating knives and a cutting table, further comprising means for moving the blades relative to the cutting table and the surface of the conveying web, and wherein the cutting means are arranged on a common element rotatable through a predetermined arc about a horizontal axis and perpendicular to the conveying direction of the conveying web where the fillet to be cut is located. on the first conveyor and wherein the conveying web is substantially linear, and the web comprises first, second and third separate conveyors arranged end-to-end for conveying the fillet through the apparatus and wherein the cutting means are arranged between the second and third transp. in the direction of movement of the conveying path, and wherein means for detecting the thickness of a fish fillet perpendicular to the thickness of the conveying path conveyed on the first conveyor provide input to the cutting means where the input is forwarded to a preprogrammed computer, where information regarding fillet size, fillet weight, cut thickness, the condition of the fillet meat and the speed of the conveyor are used by the computer to provide the cutting means with optimal parameters according to the desired output, where the output related to each fillet can be defined as a number of cut pieces, area of each piece, weight of each piece and the like, and the input is further used to control the blade movement relative to the cutting table, such as keeping the distance as short as possible.
    The process steps describe the utilization of the various features of the apparatus as already discussed above, and it is clear that the utilization of an inventive and advantageous apparatus as described above also provides a production method with all the advantages already enumerated above.

    Description of the drawing
    The invention will now be described with reference to the accompanying drawing, in which 1 FIG. 2 FIG. 3 FIG. 4 FIG. 5 FIG. 6 FIG. 7a FIG. 8 FIG. 9 shows an embodiment of the invention in a production ready state, shows the invention from an angle viewed slightly from above and with the covers 10, 11 removed, shows a close-up view of the cutting means, shows a rear view of the apparatus inside the housing, shows the cutting angle arrangement and the mechanism for adjust the cutting angle, show the details of the blades and the cutting table, show a knife held by the knife holder, show the attachment of the blades at the opposite end, show how the touch-screen layout 7 can look to the operator.
    In FIG. 1 shows an embodiment of the invention. The apparatus 1 shown is in a ready state of production, the moving parts except the conveyor belts being enclosed within protective covers 10, 11. The conveyor belt 2 is shown here as apparently continuous, but which, as described below, actually consists of three separate conveyor belts. A mechanism 3 for recording the thickness of the fish fillets arranged on the conveying web 2 is arranged upstream of the cutting mechanisms hidden by the covers 10, 11. In this embodiment, the height measuring mechanism 3 acts so that when a fish fillet is laid on the conveying web 2, it will engage with tab 4, which causes the shaft 5 to rotate, which rotation is recorded and converted to a height measurement.
    The apparatus 1 is further equipped with a control station 6 which in this embodiment comprises a touch-screen 7. Various functionalities of the touch-screen 7 will be discussed below.
    After placing fillets on the conveying web 2 and passing the height measuring device 3 and the cutting means hidden behind the covers 10, 11, the cut fillet will eventually be transferred to a package conveyor 8 arranged completely at the downstream end of the conveying web 2.
    11 DK 2012 00080 U4 In fig. 2, the apparatus 1 is shown at an angle from above and with the cover members 10, 11 removed. In this way, it is possible to see the three conveyors, where a first conveyor 9 arranged upstream of the cutting mechanism guides the fish fillets towards the thickness measuring device 3 and finally the cutting means. In this embodiment, the second conveyor 12 is shown without a conveyor belt, but it will bridge the gap between the first and third conveyors 13. The second conveyor 12 is particular in that it comprises means, e.g. in the form of spikes protruding from the surface of the conveyor belt, which spikes will be introduced into the fish meat to establish a very firm and stable connection between the conveyor belt and the fish fillet. This is necessary as the cutting means 20 will act upon the fish fillet with some force, whereby it is necessary to ensure a firm hold on the fish fillet to produce the necessary quality. The mechanism for operating and operating the cutting means 20 is partially visible, but will be explained in more detail below, and the non-visible part is enclosed in the housing 14.
    In this particular embodiment, parallel sets of conveyors 9, 9 'are arranged such that two fish fillets can be cut simultaneously by the cutting means 20. The packing station 8 comprises means under the third conveyor 13 for placing e.g. a piece of cardboard in the feed direction of the third conveyor 13 such that the cut fish fillet conveyed on the conveyor 13 will be delivered to the carton 13 for further processing, e.g. vacuum packing etc.
    In FIG. 3, a close-up view of the cutting means is shown in which certain elements are hidden.
    The cutting means 20 comprise a set of blades 40 releasably held in knife holders 41, 42 arranged at each end of the blades. Therefore, in this example, where two conveyor belts 9, 9 'are arranged in parallel, the blades 40 have relatively long cutting edges and a supporting structure 43 is provided to minimize deflection, bending, etc. of the blades 40 during operation. Since the load from the engagement with the fish along the cutting egg can be considered as evenly distributed, the fact that the blades are attached and driven at both ends of the blades will significantly reduce the load. The load depends on the square of the length, so by reducing the free length the load is reduced by the square root. The knife holders 41 are arranged in guide means 44, 45 arranged at each end of the blades 40. In this embodiment, the guide means 44 comprises two shafts 46, 46 'as well as a slider 47 which is arranged to slide upwards. and down the shaft 46, 46 '. A base plate 48 is arranged so that it can rotate about the shaft 50. The rotation occurs when the shaft 51 is moved in an arc, as will be explained below. As the shaft 51 moves along an arc, the shafts 46, 46 'will change their angle with respect to the surface 9, 9' of the conveyors.
    The slider 47 is engaged by the arms 49, 49 'to the shaft 50. As the shaft 50 is rotated back and forth as explained below, the arms 49, 49' cause the slider to move up and down along the guide shafts 46, 46 'and in turn move the blades 40 to and from the cutting table 52.
    At the opposite end of the blades, the housing cover has been removed to show the mechanism. The guiding means 45 are provided in a substantially circular plate member 53 which can be rotated back and forth as shown by arrow 54. Shafts 50, 51 are attached to this circular plate 53 so that when circular plate member 53 is rotated as shown by arrow 54 the base plate 48 is also rotated, thereby changing the angle between the blades relative to the conveyor belt surfaces.
    now seen in FIG. 4 to view the apparatus from the rear, the movement of the circular plate element 53 is restricted by the stops 55. In practice, the movement 54 of the element 53 is reciprocated by an electric stepper motor located on the back plate 100 with a gear / rack engagement with the plate 53.
    Motor means 56 exist to drive the blades 40 back and forth. The motor means 56 are mounted on a plate element 57 which in turn can be displaced along the rails 58, 58 '. The rails 58, 58 'are parallel to the guide shafts 46, 46', and the guide means 45 (see Fig. 3) provide motor means 56 with access to the knives 40 on the other side of the cover plate 45 'which are arranged in the guide means 45 and the plate member 53. For moving the plate member 57 back and forth along the rails 58, 58 'and thereby causing the blades to move with respect to the surface of the conveyor belts, the motor 60 is provided, which motor is connected to the plate 57 by means of articulated arms 6f. motor 60 by means of two arms 6f, 62 (62 is visible in Fig. 5). As the motor rotates, the arms will cause the plate member 57 to move back and forth, thereby moving the motor means up and down along the rails 58, 58 ', and in the same way the opposite end of the knife / cutting member along the guide shaft 46, 46 ', such that the blades 40 will cut into e.g. a fish fillet conveyed by the conveyors into the cutting means 20 as described above.
    The arms 63, 64 will transmit the movement of the plate member 57 to the shaft 50, which will manipulate the arms 49, 49 'such that the slider member 47 will slide along the guide shaft 46, 46' at exactly the same speed as the plate member 57. In this way, the blades 40 will be actively moved at both ends of the blades with relatively rigid sliding and guide members such that a uniform and very stable construction achieves a very accurate cutting action of increased quality.
    As already discussed earlier, it is very important to obtain a perfect cut that the blades 40 engage the cutting table 70 (see Fig. 6). When the cutting table 70 is fixedly fixed to the base plate 48 by means of the arm 71, see fig. 3, the blades 40 will always have the same angle with respect to the cutting table 70, such that the zero point, i.e. the point at which the optimal cutting is achieved is always kept at the optimum angle.
    Referring to FIG. 7a, 7b, 8a and 8b, the inventive principles relating to how the knives are fastened in the apparatus and the knives themselves are discussed. In FIG. 7a shows a knife 40 held by the knife holder 42. In addition, the guide shafts 46, 46 'and the slider element 47 are also seen.
    The knife holder 42 comprises a first portion 81 which is more or less identical to the supporting structure 43 already mentioned above. The member 81 is attached to the arm 90, which in turn is rigidly connected to the slider member 47. The end 110 of the blades 40 is provided with blunt edges so that they do not wear on the member 81. The member 82 will, after the end 110 is placed in the slot. in the member 81 being overlaid such that the member 82 will hold the end 110 in the slot present in the member 81. By further placing the screw 80 (see Fig. 7b) in superimposed openings in the members 82 and 81 and securing it, f. eg. with an internal thread provided in the member 81 or with a nut, it is impossible for the knife end 110 to be released from the knife holder 42.
    14 DK 2012 00080 U4
    However, the arrangement allows the two knives 40 to reciprocate in the direction indicated by arrow 91.
    The attachment 41 of the blades 40 at the opposite end will be described with reference to FIG. 8a and 8b.
    Since there are two reciprocating knives 40, two knife holders 92, 93 are needed for the two knives to be independently attached to reciprocating means 56. Knife holders 92, 93 comprise a main body 111 as well as a closure member 112 for holding knife. The closure element 112 has been removed in FIG. 8b, and as shown in the explosion drawing, the closure member may be pivotally mounted on the main body 111 and when closed, a screw may be inserted to provide an open holder as shown with reference to Figs. 8a and 8b. Adjoining the end of the knife 40, a projection 115 is welded in the form of a short cylinder, e.g. made of the same material as the blades so that it protrudes at a 90 ° angle to the plane of the blade 40.
    The holder 92, 93 will be arranged for loose engagement with the projection 115 such that the double holders 92, 93 will hold the blades in the holders due to the relatively short distance between the two holders 92, 93. At the same time, the blades will be held for reciprocating reciprocating motion. When replacing the blades, the open element 112 is aligned, and then the blades as explained with reference to FIG. 7a and 7b are only loosely held at the opposite end, it is very easy to remove the blades, insert a new set of knives and simply place the screws in the open member 112 close, thereby fixing the blades in the holder 92, 93, and the machine is ready for to work again.
    Since the holders 92, 93 are further arranged in a position where they are accessible without having to remove the conveyor belts, it is quite easy to replace the blades, whereby short operating stops can only be expected should a knife fail or need to be replaced due to wear.
    In FIG. 9 shows how the touch-screen layout 7 can look to the operator. A longitudinal cross-section of a fish fillet 120 is shown schematically in longitudinal cross-section. The cross section is 15 DK 2012 00080 U4 divided into four sections 121-124. For each section, it is possible to adjust the length by selecting the values in the first row 125 such that e.g. the section 121 of this example is shown as being from 0 to 20 mm, the second section 122 from 20 to 175 mm, and so on.
    Initially, the average size of the fish fillets in this case is chosen to be about 500 mm as indicated in window 126. The thickness of the cut pieces in each section can be selected in row 127. In this example, the first section 121 will have a cut thickness of 2.8 mm and the third section will have a cut thickness of 3, for example. mm.
    In the third row 128, the angle of the blades relative to the surface of the conveyor can be selected. In this example, the angles in the different sections can vary between 12 and 15 °. Each of these parameters can be set manually or a pre-programmed set of data can be selected, e.g. the value in 126 could be selected, ie a fillet of 500 mm length and the desired cut thickness in row 127. Based on this, the computer will refer to stored data and the preprogrammed data to select the correct length of sections 121-124 and the correct cutting angles in row 128.
    The system can also be programmed such that a desired weight of each cut piece is optionally entered into each section, after which the software determines the cutting parameters. In fact, any input can be used to make the software perform the desired cutting process.
