Abstract
Description
[0001] Cutting device for cutting a substantially V-shaped strip from meat products fed in the transport direction T, and method and device for removing a substantially V-shaped strip from meat products fed in the transport direction T with such a
[0002] Cutting device
[0003] Description
[0004] The invention relates to a cutting device, designed and configured for cutting a substantially V-shaped strip of meat products fed in the transport direction T, with a knife carrier to which two knife units are assigned, wherein each knife unit comprises a circular knife and a drive for rotating the circular knife about a central axis of rotation Mi, M2, wherein the two circular knives are positioned substantially in a V-shape relative to each other in a position enclosing an angle a and the size of the angle a is adjustable by an adjustable arrangement of the knife units on the knife carrier.
[0005] The invention also relates to a device for removing substantially V-shaped strips from meat products fed in the transport direction T, comprising a transport conveyor for transporting the meat products to be processed in the transport direction T, means for recognizing specific characteristics of the
[0006] Meat products, a cutting device for cutting an essentially V-shaped strip from the meat product, and a control device for controlling the cutting device depending on the determined characteristics.
[0007] The invention further relates to a method for removing essentially V-shaped strips from materials fed in the transport direction T.
[0008] Meat products, in particular with a device according to claim 14, comprising the steps of: transporting the meat products in the transport direction T by means of a transport conveyor, recognizing specific characteristics of the meat products by means of recognizing the specific characteristics of the meat products, cutting a substantially V-shaped strip from the meat product by means of a cutting device having two circular blades, wherein the two circular blades are set in a position enclosing an angle a in a substantially V-shaped manner relative to each other and the size of the angle a is adjusted depending on the characteristics, wherein the cutting device, when cutting the V-shaped
[0009] Strips depending on the determined characteristics by means of a
[0010] The control device is controlled.
[0011] Such cutting devices and equipment are used in the food processing industry in processes where a preferably V-shaped strip is to be cut from a meat product. Particularly in the processing of meat, which explicitly includes fish, such cutting devices are used to cut product strips, for example, from a fish fillet lying on a transport surface or conveyor. This is done by...
[0012] Relative movement between the meat products being processed and the
[0013] Cutting device. It is possible for the meat product to remain stationary while the cutting device, e.g., a handheld device, is moved over the meat product. However, the meat product usually and preferably lies on a
[0014] Conveyor by means of which the meat product is transported in the transport direction T, along a transport path on which the cutting device (in the transport direction) is fixedly placed, so that the cutting device can be brought into contact with the meat product.
[0015] A continuously driven conveyor belt, typically used as a transport device, carries the meat products, preferably flat products such as fish fillets or the like. A means for determining specific product characteristics is used to identify these characteristics before the products reach the cutting device. Determining these characteristics means, for example, identifying fat strips, strips of dark meat, bones, or other components.
[0016] Bone strips or other unwanted strips, such as bloodstains in meat, are detected and identified with regard to their size, location, direction, and orientation within the meat product. This detection is typically performed using devices such as cameras, X-ray machines, sensors, measuring arms, or similar equipment. The collected data / information is then processed and evaluated by the control unit to individually control the cutting device based on the identified characteristics, particularly during the cutting process. The cutting device therefore plays a crucial role in removing these unwanted V-shaped strips.
[0017] In known cutting devices, e.g. from DK 2004 00450 L, the
[0018] Circular blades are arranged one behind the other, offset from each other, in the transport direction T. In other words, the circular blades lie with their axes of rotation in
[0019] Viewed from the transport direction T, the circular blades are positioned sequentially, meaning they strike the meat product being transported in transport direction T one after the other, i.e., with a time offset. This results in staggered cuts, creating the risk of the product's position / orientation changing during cutting. In other words, the spatially and temporally staggered entry of the circular blades into the meat product being processed causes the product to twist on the conveyor, as the staggered arrangement of the circular blades applies a moment to the product. This ultimately impairs the cutting pattern and thus the cutting quality. Furthermore, in the known solution, the circular blades are independent.
[0020] The circular blades can pivot independently of each other. This leads, firstly, to variations in the position / orientation of the contact point B of the circular blades, resulting in an asymmetrical V due to different settings / adjustments of the circular blades. The contact point B of the circular blades is the point where the two V-shaped circular blades, or the planes E1 and E2 spanned by the circular blades, intersect. It is therefore not an actual point of contact, but rather the point of smallest distance. Secondly, the independent pivoting of the two circular blades is difficult to reproduce, so the result of the adjustment depends on the individual operator. A further disadvantage of the known cutting device is that the drives for adjusting the blade carrier and the blade units are located on the blade carrier itself, which ultimately necessitates the movement of additional masses.
[0021] The invention is therefore based on the objective of creating a compact cutting device that ensures symmetrical and precise cutting of the products. The objective further includes proposing a corresponding device and a method.
[0022] This task is solved by a cutting device of the type mentioned above in that the offset V of the two rotary axes M1, M2 from each other in the transport direction T is zero, and the two knife units are designed and set up to be adjustable exclusively synchronously with each other. An offset V of zero means that the rotary axes M1, M2 of the two
[0023] The circular blades are perfectly aligned with respect to the transport direction T, meaning they lie side-by-side with zero distance in the transport direction T, such that the circular blades strike the meat product being processed synchronously and simultaneously. "Exclusively synchronous" means that the two blade units are directly or indirectly coupled or operatively connected, ensuring that both blade units always adjust identically and uniformly with regard to timing and control variable. Adjusting one blade unit inevitably leads to...
[0024] Adjustment of the other knife unit and vice versa. However, "synchronous" does not necessarily mean that the adjustment is symmetrical, e.g., to a vertical axis.
[0025] The center axis or the vertical axis of rotation D must be involved. Through this
[0026] The combination of features avoids or at least greatly reduces the risk of twisting or shifting the meat products being processed, resulting in symmetrical and precise cuts that can be reproduced as desired.
[0027] In a particularly preferred embodiment, each knife unit is arranged on a separate actuating body for the synchronous pivoting of both knife units, wherein each actuating body has an arc-shaped actuating rail with a toothed section, and the two actuating bodies with their arc-shaped actuating rails and their respective toothed sections are mounted on the knife carrier facing each other. Through the
[0028] The adjusting elements, with their arc-shaped adjusting rails, enable synchronous adjustment of the circular blades with a constant contact point B in a particularly simple and compact manner. This ensures the cutting of symmetrical V-cuts.
[0029] Advantageously, there is an interlocking connection between the two parts.
[0030] A common drive pinion is arranged on curved adjusting rails, which is operatively connected to both adjusting rails, with a drive unit assigned to the drive pinion. The drive unit can be driven in both directions, thus enabling precise and synchronous adjustment of the angle 'a' for symmetrical cuts. The common, central drive pinion ensures synchronous adjustment of the cutting units.
[0031] According to the invention, the two actuating elements, and thus the knife units, have a common pivoting axis S. Due to the common pivoting axis S as an imaginary pivoting axis, the contact point B of the circular knives is reliably and necessarily held in a constant position, namely on the
[0032] Swivel center axis S.
[0033] A preferred embodiment is characterized in that the actuating elements have bearing bodies with which the actuating elements move along an arc-shaped
[0034] The tracks are guided by a guide, with the tracks being arranged on the knife carrier. This design ensures safe and precise adjustment of the angle 'a'.
[0035] According to the invention, the radius of the arc-shaped raceways corresponds to the radius of the arc-shaped guide rails. This geometric adaptation ensures the precise and synchronous pivoting of the two knife units in a particularly simple and safe manner.
[0036] Advantageously, the bearing bodies for each actuator comprise four roller elements, two of which are guided on the top and two on the underside of the curved raceway. This ensures secure and wobble-free bearing / guiding of the actuators on the knife carrier for precise operation.
[0037] Setting and adjustment of the angle a is guaranteed.
[0038] Preferably, the contact point B of the two circular blades is constant with respect to its position, regardless of the size of the angle α. Particularly preferably, the contact point B of the two circular blades lies on the pivot axis S of the arcuate guide rails and the central axis of the arcuate raceways. This further enhances the advantages already described.
[0039] A preferred further education program is characterized by the fact that it offers additional
[0040] Guide rollers are provided, which are arranged on the knife carrier and bear against the adjusting elements or the adjusting rails on the side opposite the toothing. "Bearing" refers not only to the contact of the guide rollers against the
[0041] Guide rails also refer to the guiding of the guide rollers at a small distance from the guide rails. This ensures the safe and precise guidance of the guide elements and thus precise and symmetrical cutting of the products. A particularly advantageous feature is that the circular blades can be driven independently of each other via their drives. This allows both the cutting speeds and the directions of rotation of the two circular blades to be varied individually.
[0042] The knife carrier is particularly preferably attached to a robot mechanism that has several axes of movement, such that the knife carrier can be rotated about a vertically directed axis of rotation D and / or vertically perpendicular to the
[0043] The transport plane E is designed to be movable up and down and / or horizontally back and forth, transverse to the transport direction T and parallel to the transport plane E.
[0044] Robot mechanics can be, for example, a robot arm. Other mechanisms, such as so-called delta robots or the like, can also be used. The cutting device according to the invention, i.e., the combination of the cutting device with a robotic mechanism, allows individual cuts to be executed simply and precisely, thus ensuring reproducible symmetrical V-cuts.
[0045] Particularly preferably, the robot mechanism additionally includes a shaft for driving the drive pinion, with the drive for the drive pinion being assigned to the shaft. This means that all (positioning) drives are fixed to the frame, i.e., not to the knife carrier itself, so that less mass needs to be moved.
[0046] The problem is also solved by a device of the type mentioned above in that the cutting device is designed and set up according to one or more of claims 1 to 13.
[0047] The task is further solved by a method with the steps mentioned at the outset, whereby the two circular knives simultaneously hit the meat product transported in the transport direction T, such that the cutting of the meat product is carried out simultaneously by both circular knives, and that the adjustment of the size of the angle a is carried out exclusively by the synchronous adjustment of both circular knives.
[0048] The resulting advantages have already been described in connection with the cutting device, therefore reference is made to the relevant passages to avoid repetition.
[0049] Further suitable and / or advantageous features and further developments of the cutting device as well as of the device and method for removing substantially V-shaped strips from material fed in the transport direction T
[0050] Meat products are derived from the dependent claims and the description. Particularly preferred embodiments of the cutting device and the apparatus are explained in more detail with reference to the accompanying drawing. The drawing shows:
[0051] Fig. 1 shows a schematic representation of a cutting device in a perspective view from an oblique angle above and from the front,
[0052] Fig. a front view of the cutting device according to Figure 1 viewed in transport direction T with a steep angle of the circular blades (small angle a),
[0053] Fig. 3 shows a front view of the cutting device according to Figure 1 viewed in the transport direction T with a shallow angle of the circular blades (large angle a), Fig. 4 shows a top view of the cutting device according to Figure 1 ,
[0054] Fig. 5 shows a bottom view of the cutting device according to Figure 1.
[0055] Fig. 6 shows a side view of the cutting device according to Figure 1, and
[0056] Fig. 7 shows the cutting device according to Figure 1, arranged on a robot mechanism.
[0057] The cutting device shown in the drawing is used to remove dark strips of meat (so-called dark meat) from skinned fish fillets, e.g., pink salmon or tuna. The cutting device according to the invention is also used in the same way to remove strips of fat, bones, meat, or other unwanted product strips from other
[0058] Meat products, such as poultry or the like.
[0059] The illustrated cutting device 10 is designed and configured for cutting a substantially V-shaped strip 50 of meat products 1 1 fed in the transport direction T and has a knife carrier 12 to which two
[0060] Knife units 13, 14 are assigned, with each knife unit 13, 14 having a
[0061] Circular blades 15, 16 and a drive 17, 18 for rotating the
[0062] circular knives 15, 16 about a rotational axis M1, M2, wherein the two circular knives 15, 16 are arranged in a position enclosing an angle a in a substantially V-shaped manner relative to each other and the size of the angle a is adjustable by an adjustable arrangement of the knife units 13, 14 on the knife carrier 12.
[0063] This cutting device 10 is characterized according to the invention in that the offset V of the two rotary axes M1, M2 from each other in the transport direction T is zero, and the two knife units 13, 14 are designed and configured to be adjustable exclusively synchronously with each other. The offset-free arrangement of the two rotary axes M1, M2 is shown in particular in Figure 5. In their basic position, the two rotary axes M1, M2 lie next to each other on one axis, this axis being ideally oriented transversely to the transport direction T. The synchronous adjustability of the two knife units 13, 14 results in
[0064] Expression that a single knife unit 13, 14 cannot function without the other
[0065] The knife unit 13, 14 is adjustable.
[0066] The features and further developments described below represent preferred embodiments, either individually or in combination. It is expressly pointed out that features summarized in the claims and / or the description and / or the drawing, or described in a common embodiment, can also functionally and independently further develop the cutting device 10 described above.
[0067] The two circular blades 15, 16 are particularly preferably always and in every position (see especially Figures 2 and 3) symmetrical to the axis of rotation D of the
[0068] Knife carrier 12. The angle α is divided equally into a1 = a2. The axis of rotation D forms the angle bisector for angle α. Optionally, the two circular knives 15, 16 can also be aligned asymmetrically with respect to the axis of rotation D. That is, a1 is not equal to a2. The synchronous adjustment with respect to the angle bisector, which is then no longer formed by the axis of rotation D, remains unaffected.
[0069] In the illustrated embodiment, the knife carrier 12 is a flat profile 19 with a support plate 20. Other designs of the knife carrier 12, e.g., in the form of a frame or the like, are also possible. The knife units 3, 14 arranged on the knife carrier 12, which are preferably detachably attached, each comprise a circular knife 15, 16 and a drive 17, 18. The drives 17, 18 for the circular knives 15, 16 can be, for example, pneumatic motors or
[0070] Electric motors. The power transmission from the drive 17, 18 to the circular blades 15,
[0071] 16 can be achieved, for example, via timing belts or gear transmissions. Others
[0072] Drive concepts and transmission concepts can also be used.
[0073] The adjustable arrangement of the knife units 13, 14 on the knife carrier 12 allows the angle α to be adjusted, preferably between 170° and 45°, and particularly preferably between 160° and 85°. The adjustment is preferably stepless. The diameter of the circular knives 15, 16 is chosen to be as small as possible in order to reduce the influence of the circular knives 15, 16 on the meat product 11 when they pivot, thus minimizing displacement and / or rotation of the meat product 11.
[0074] Optionally, each knife unit 13, 14 can be used for synchronous swiveling of both
[0075] Knife units 13, 14 are arranged on a separate actuating body 21, 22, each actuating body 21, 22 having an arcuate actuating rail 23, 24 with a toothing 25, 26 and the two actuating bodies 21, 22 with their arcuate actuating rails 23,
[0076] The knife units 24, with their respective teeth 25, 26 facing each other, are mounted on the knife carrier 12. In this embodiment, the knife carrier 12 is sandwiched between the two adjusting bodies 21, 22. The knife units 13, 14 are detachably attached to the adjusting bodies 21, 22, e.g., by means of screws. Instead of the
[0077] Adjusting rails 23, 24 with the toothed sections 25, 26 can also be used for other purposes.
[0078] Actuating mechanisms, e.g. gear constructions or actuating levers or the like, are used.
[0079] Between the two arc-shaped [parts] having the toothing 25, 26
[0080] A common drive pinion 27 is arranged between the adjusting rails 23 and 24, and is operatively connected to both adjusting rails 23 and 24. A drive 28 is associated with the drive pinion 27. The drive 28 can be directly connected to the drive pinion 27 or indirectly, e.g., via a toothed belt or gear transmission. In a preferred embodiment, which is described below, the drive 28 is connected to the drive pinion 27 via a shaft 29 for power transmission.
[0081] The teeth of the drive pinion 27 engage directly with the teeth 25, 26 of the
[0082] Adjusting rails 23, 24. The adjusting rails 23, 24 are detachably attached to the adjusting body 21, 22, e.g. by means of screws 30. This allows for easy replacement of the
[0083] Adjustable rails 23, 24 possible, e.g. in case of wear or for different applications
[0084] Gears with modified pitches. The two adjusting elements 21, 22, and thus the knife units 13, 14, have a common pivot axis S. The pivot axis S is particularly visible in Figures 2 and 3. The adjustment of the circular knives 15, 16 is synchronized due to the common pivot axis S. The pivot axis S coincides with the point of contact B of the two circular knives 15, 16. In other words, the point of contact B of the circular knives 15, 16 lies on the
[0085] Swivel center axis S. The point of contact B of the two circular blades 15, 16 is the point of smallest distance that just prevents a collision between the two circular blades 15, 16. Swivel center axis S and point of contact B are oriented with respect to their
[0086] The position / location is independent of the position of the circular knives 15, 16 and thus independent of the size of the angle a, and in the embodiment shown lies on the axis of rotation D of the cutting device 10 (see in particular Figures 2 and 3).
[0087] As mentioned, the actuating elements 21, 22 are mounted on the knife carrier 12. For this purpose, the actuating elements 21, 22 have bearing bodies 31, 32, with which the actuating elements 21, 22 are guided along an arcuate raceway 33, 34, the raceways 33, 34 being arranged on the knife carrier 12. Preferably, the arcuate
[0088] The raceways 33 and 34 are detachably attached to the knife carrier 12, for example by means of screws 35. The knife carrier 12 is again arranged in a sandwich-like configuration between the raceways 33 and 34. The curvature of the arcuate raceways 33 and 34 corresponds to the curvature of the arcuate guide rails 23 and 24. The curved tracks St and L run parallel to each other. Starting from the pivot axis S, the radius of the guide rails 23 and 24 is R. St , while the radius of the raceways 33, 34 starting from a central axis MR L is, where R St >R L (see
[0089] (especially Figure 2). The point of contact B of the two circular knives 15, 16 lies both on the pivoting central axis S of the arc-shaped adjusting rails 23, 24 and on the central axis M of the arc-shaped raceways 33, 34.
[0090] Each bearing body 31, 32 comprises four roller elements 36, 37; 38, 39 for each adjusting body 21, 22, of which two roller elements 36, 38 are on the top and two
[0091] Roller elements 37, 39 are guided on the underside of the curved raceways 33, 34. The number and arrangement of the roller elements 36, 37; 38, 39 ensure that the actuating bodies 21, 22 are securely and precisely mounted and guided on the knife carrier 12. The roller elements 36, 37; 38, 39 are preferably detachably attached to the actuating bodies 21, 22, e.g., by means of screws. Optionally, additional guide rollers 40, 41 are provided. Preferably, the guide rollers 40, 41 are arranged on the knife carrier 12, e.g., in the area of the support plate 20. The guide rollers 40, 41 bear against the adjusting elements 21, 22 or the adjusting rails 23, 24 on the side opposite the toothing 25, 26, whereby guiding with a small distance between the guide rollers 40, 41 and the adjusting rails 23, 24 is also referred to as "bearing against". The number of roller elements 36 to 39 can also vary. For example,Two roller elements are guided on the upper side of raceways 33, 34 and one roller element on the lower side of raceways 33, 34, or vice versa. Instead of the.
[0092] Roller elements 36 to 39 can also be used, for example, as plain bearings.
[0093] It was already described above that each circular blade 15, 16 is assigned a drive 17, 18. This means that the circular blades 15, 16 can be driven independently of each other by means of their drives 17, 18. Therefore, the circular blades 15, 16 can be driven in the same direction or, preferably, in opposite directions.
[0094] The drive speed can also be selected differently. Preferably, however, the drive speed for both circular knives 15, 16 is selected to be identical.
[0095] Preferably, the cutting device 10 has a (not explicitly shown) suction unit for extracting the strips 50 cut from the meat product 11. The suction unit comprises, among other things, a suction tube whose suction opening is directed approximately towards the point of contact B of the circular blades 15, 16, and a
[0096] Vacuum unit to which the suction pipe is connected.
[0097] Particularly preferably, the knife carrier 12 is attached to a robot mechanism 42 which has several axes of movement, such that the knife carrier 12 can be rotated about a vertically directed axis of rotation D and / or vertically perpendicular to the
[0098] Transport plane E can be moved up and down (in the Y direction, e.g., according to Figures 2 and 3) and / or horizontally back and forth, transverse to the transport direction T, parallel to the
[0099] The transport plane E (in the X-direction, e.g., according to Figures 2 to 5) is designed. The robot mechanism 42 has several drives 43, 44, 45 for executing the
[0100] Adjustment movement for positioning the cutting device 10 along the axes of movement. Additionally, the robot mechanism 42 can also include the drive 28, by means of which the shaft 29 is driven to drive the drive pinion 27 for the adjustment movement of the knife units 13, 14. The knife carrier 12 can also be arranged on a serial actuator or a parallel kinematic system to, for example, realize an additional movement in the transport direction T (Z-direction).
[0101] As already mentioned, the cutting device 10 can be used as a separate component. Preferably, the cutting device 10 is, as described above, i.e., with or without robot mechanics 42, but is part of a device 46 for
[0102] Removal of substantially V-shaped strips 50 from meat products 11 fed in the transport direction T, comprising a transport conveyor 47 for
[0103] Transporting the meat products to be processed 1 1 in the direction of transport T, means 48 for recognizing specific characteristics of the meat products 11 , a
[0104] Cutting device 10 for cutting an essentially V-shaped strip 50 from the meat product 11, and a control device 49 for controlling the cutting device 10 depending on, i.e., based on the determined
[0105] Characteristics.
[0106] According to the invention, the device 46 is characterized in that the
[0107] Cutting device 10 is designed and configured according to one or more of claims 1 to 13, i.e., according to the preceding description for
[0108] Cutting device 10 in different embodiments.
[0109] The transport conveyor 47 is preferably a continuously driven conveyor.
[0110] Conveyor belt. The conveyor belt is driven intermittently or preferably continuously by means of the drive (not shown). The meat products 11 are aligned with their longitudinal extent in the transport direction T, such that the strips 50 to be removed, which are made of dark meat (e.g., pink salmon or tuna), run lengthwise along the fillets, are also aligned approximately in the transport direction T. In this orientation, the meat products 11 are fed to the cutting device 10. Upstream of the cutting device 10 in the transport direction T is the means 48 for detecting the specific
[0111] Characteristics of meat products are arranged in 11.
[0112] Determining characteristics means that, for example, streaks of fat, strips of dark meat, bones or bone lines, or other undesirable streaks, such as bloodstains, are identified and determined with regard to size, location, course, and orientation within the meat product. This identification is typically carried out using, for example, cameras, X-ray machines, sensors, measuring arms, or similar devices, with the collected data / information being processed by the...
[0113] Control device 49 processes and evaluates in order to
[0114] Cutting device 10 can be individually controlled on the basis of the determined characteristics or depending on the determined characteristics, particularly also during the execution of the cut.
[0115] The robot mechanism 42 is preferably mounted on a housing or a
[0116] The frame is attached. Accordingly, in the preferred embodiment, all drives 43, 44, 45, and 28 for positioning the cutting device 10 on the one hand and for adjusting the knife units 13, 14 on the other are also fixedly arranged in the frame. Preferably, all drives 43 to 45 and 28 are connected to the
[0117] The control unit 49 is connected, which may optionally also include an evaluation unit and / or a storage unit. The means 48 for recognizing the characteristics is also connected to the control unit 49.
[0118] Additionally, there is still the possibility that the drive for the
[0119] The transport conveyor 47 is connected to the control device 49.
[0120] The method according to the invention is described in more detail below with reference to the drawing:
[0121] The method is used to remove substantially V-shaped strips 50 from meat products 11 fed in the transport direction T. The method is particularly preferably used to remove / cut out a strip 50 of dark meat from a fish fillet. The method comprises the following steps:
[0122] The meat products 11 are transported by means of a conveyor belt 47 into
[0123] The meat products 11 are transported in the direction of transport T. For this purpose, the meat products 11 lie flat on the conveyor 47 and are transported with their longitudinal extension in the direction of transport T. During transport, the meat products 11 are guided under a device 48 for recognizing the specific characteristics of the meat products 11. The device 48 determines the specific characteristics of the meat products 11. Subsequently, a substantially V-shaped strip 50 is extracted from the
[0124] Meat product 1 is cut using a cutting device 10 comprising two circular blades 15, 16, wherein the two circular blades 15, 16 are positioned in a substantially V-shape relative to each other, enclosing an angle α, and the size of the angle α is adjusted depending on the characteristics. The adjustment can be made before and / or during the cutting process. Accordingly, the cutting device 10 is controlled by a control unit 49 when cutting the V-shaped strip 50, depending on the determined characteristics. The method is characterized according to the invention in that the two
[0125] Circular knives 15, 16 simultaneously onto the object transported in the direction of transport T
[0126] Meat product 1 1 is cut in such a way that the cutting of the meat product 11 is carried out simultaneously by both circular knives 15, 16, and that the adjustment of the size of the angle a is carried out exclusively by the synchronous adjustment of both circular knives 15, 16. Ultimately, the two knife units 13, 14 or the circular knives 15,
