Description

[Technical Field]

[0001] The present invention relates to a slicing device that is particularly useful for cutting fillets such as sushi toppings from a fillet of fresh fish. [Background technology]

[0002] In the seafood processing industry, processes such as removing scales from fish, filleting fish, and slicing fish meat into sashimi are being increasingly mechanized.

[0003] For example, Patent Document 1 proposes a device that, when cutting fillets from a stock, makes it possible to divide and cut the fish body into multiple pieces of the desired weight when the fish body to be cut is irregular. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 56-18539 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, the demand for sushi has been increasing both domestically and internationally. However, the preparation of sushi ingredients is still done entirely by hand, and mechanization has not progressed. The sushi industry in particular is facing a labor shortage due to a decline in the working population and a shortage of craftsmen, and is struggling to produce the desired amount of processed food even outside of peak seasons. Sushi chains also face the same challenge of securing personnel.

[0006] One reason why sushi ingredients are not being automated is that they must be particularly fresh, so the fish cannot be sliced ​​in a frozen or semi-thawed state, and they are difficult to slice because they are soft. In addition, unlike sashimi, sushi ingredients must bend to cover the rice when placed on top, so the length and width dimensions of the fillets must be relatively large compared to the thickness. Also, the cutting method must change depending on the shape of the sashimi.

[0007] In particular, if there are tough parts near the tendons or skin inside the fillet, it will be difficult to cut, and the quality of the fillets will be affected when cutting.

[0008] Due to these circumstances, it has not been possible to effectively mechanize the processing of soft fillets such as those used for sushi toppings.

[0009] One solution to this problem is to swing the blade in the blade length direction while lowering it to cut the fillets from the fence. The method of swinging the blade horizontally while lowering it to cut the fence has the advantage of reducing the amount of blade movement and making the device more compact.

[0010] However, if a groove for the blade to fit into is provided on the conveying surface that conveys the fence in order to cut the fillets from the fence, the fillets will sink into the groove when the blade moves back and forth within the groove, resulting in an inconvenience that the fillets will not be cut properly. Also, if a rubber sheet is used on the conveying surface to cut the fillets without creating a cut-out groove, the rubber sheet will be scraped off and mixed in with the fillets as foreign matter, making them unsuitable for sale.

[0011] Considering the above, one effective solution to cutting fillets from soft stock is to use movements similar to those of a craftsman using a knife.

[0012] SUMMARY OF THE INVENTION An object of the present invention is to realize a new slicing device that incorporates a pulling and cutting action that is closer to the knife handling of a craftsman when slicing an object to be sliced ​​that has the above-mentioned circumstances. [Means for solving the problem]

[0013] In order to achieve the above object, the present invention takes the following measures.

[0014] In other words, the slicing device of the present invention uses a blade to sequentially slice the slicing object transported on a conveying surface, and is equipped with a pull-cutting mechanism that moves the blade in the blade length direction while cutting into the slicing object.The pull-cutting mechanism is characterized in that a single movement of the blade in one direction is the basic slicing operation, and the cutting angle between the blade length direction of the blade and the conveying surface during this operation can be set.

[0015] In this way, the blade moves in the direction of the blade length at a certain cutting angle, achieving an action similar to that of a craftsman's pull-cutting technique. In other words, the area where the blade comes into close proximity to the conveying surface is limited, and deformation of the fence or fillet due to the force applied from the blade to the sliced ​​material is minimized, and it is possible to properly slice pieces with a short stroke while preventing any uncut pieces.

[0016] In this case, it is preferable to provide a cutout groove on the conveying surface side into which the blade near the end in the blade length direction can enter.

[0017] Even if the cutting blade is inserted, the actual cutting into the material to be sliced ​​begins near the middle of the blade length, and the material to be sliced ​​is only cut off in the groove when the blade passes the end of the blade length. This prevents the blade from scraping the conveying surface and reduces the risk of the material to be sliced ​​becoming embedded in the cutout groove.

[0018] In a preferred embodiment, the blade has a cutting edge that is approximately linear at an angle, and by keeping the cutting angle constant and moving the cutting edge approximately horizontally with the cutting edge partially inserted into the cutout groove, the blade cuts into the object to be sliced ​​from midway along the blade length, and the slicing operation ends at the position where the terminal end of the blade length crosses the object to be sliced.

[0019] In this way, cutting can be achieved by simply moving the blade.

[0020] In another preferred embodiment, the blade has a curved cutting edge, and the entire blade rotates and moves downward in the blade length direction, cutting into the object to be sliced ​​halfway along the blade length, gradually increasing the cutting angle until the end of the blade length enters the groove and finishes slicing at a position where it has crossed the object to be sliced.

[0021] In this way, the cutting angle is not so deep that the fence or the cut piece moves and becomes displaced, and the stroke in the blade length direction of the blade is made as small as possible, so that the cutting can be performed by pulling the blade.

[0022] Alternatively, it is preferable that the device further includes a slice angle change mechanism that changes the slice angle between the blade width direction of the blade and the conveying surface, and that a pull-cutting mechanism be provided on the movable part of the slice angle change mechanism, or that a slice angle change mechanism be provided on the movable part of the pull-cutting mechanism.

[0023] In this way, the width of the fillet can be set at the same time.

[0024] In this case, it is preferable that the position of the cutting edge when the blade is at its lowest position is set to be the center point of the angle change.

[0025] In this way, no matter what angle is changed, the position at which the bottom of the fence is cut remains the same, and it is possible to reliably prevent any part of the fence from being left uncut. [Effects of the Invention]

[0026] According to the present invention as described above, it is possible to provide a new slicing device that incorporates a pulling and cutting action that is closer to the knife skills of a chef when slicing an object to be sliced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0029] As shown in Fig. 2, the slicing device of this embodiment is for automatically cutting sushi-sized fillets a from a fillet A obtained from the body of a fresh fish. The fillets A in this embodiment are, for example, filleted salmon processed into blocks. Of course, the type of fish to be sliced ​​into fillets A is not limited to salmon (fresh salmon), and the process for obtaining the fillets A is not limited to filleting.

[0030] FIG. 1 is a schematic diagram showing a slicing device 2 that produces fillets from a fence A. A conveyor 1, which forms an endless track, is driven by a motor M1, and fence A placed on the conveying surface 1a of the conveyor 1 is transported in the direction of arrow V0 toward the slicing device 2, where it is sliced ​​by the slicing device 2. Each time the slicing device 2 operates and cuts out a fillet a, the conveyor 1 intermittently feeds fence A by an amount equivalent to the thickness of the fillet a, in preparation for slicing the next fillet a. Control of motor M1 and slicing device 2 is managed by control means 3.

[0031] The control means 3 includes a microcomputer unit consisting of a CPU, memory, and interface, and the memory stores required programs and necessary data. The CPU sequentially reads the programs and executes various controls in this embodiment in cooperation with peripheral hardware resources. Setting values ​​Z for various slicing conditions and the like are input to the control means 3 through a setting unit 30.

[0032] In the slicing device 2, the blade 21 is arranged so that the direction intersecting the conveying direction of the conveyor 1 is the blade length direction (blade length direction).

[0033] 2(a) shows the fence A and the blade 21, FIG. 2(b) is a view of the fillet a being cut by the blade 21 as seen from above the conveying surface 1a, and FIG. 2(c) is a view of the fillet a being cut by the blade 21 as seen from the side of the conveying surface 1a. The arrow V in FIG. 2(b) indicates the longitudinal direction of the fence A, which normally coincides with the conveying direction V0 of the conveying surface 1a. As shown in these figures, the blade length direction (blade length direction, X direction) of the blade 21 is the longitudinal direction (longitudinal dimension L) of the fillet a, the blade width direction (blade width direction, cutting edge direction, Y direction) of the blade 21 is the lateral direction (lateral dimension W) of the fillet a, and the feed pitch of the fence A for each pass is the thickness dimension D of the fillet a. The length L, width W and thickness D of fillet a must satisfy the specified dimensions L0, W0 and D0 as the fixed weight size, since fillet a must bend to cover and conceal sushi rice B when placed on top of it, as shown in Figure 2(d).

[0034] Therefore, in case the dimensions are insufficient, the slicing device 2 is configured to achieve the appropriate longitudinal dimension L0 of the fillet a by setting a first relative angle θ1 between the conveying direction V of the fence A and the blade length direction (X direction) of the blade 21, to achieve the appropriate transverse dimension W0 of the fillet a by setting a second relative angle θ2 between the conveying direction V of the fence A and the blade width direction Y of the blade 21, and to achieve the appropriate thickness dimension D0 of the fillet a by setting the conveying pitch of the fence A.

[0035] However, even if a setting can be made to obtain the appropriate size of fillet a, because the sashimi A that will be used as sushi topping is fresh and soft, there is a problem that when cutting thin fillet a from sashimi A, sashimi A and fillet a tend to move and become unstable.Furthermore, if there is any sinew or skin inside sashimi A, it will be difficult to cut, and the condition of fillet a will be easily affected when cutting.

[0036] In addition, when the blade is lowered while swinging it horizontally, the fillets are likely to get caught between the blade and the cutout groove, and if the cutout groove is eliminated and the conveying surface is made of a rubber sheet, the rubber can be scraped off and get mixed into the product, which is an inconvenience.

[0037] Therefore, as shown in Fig. 3, the slicing device 2 of this embodiment employs a pull-cutting mechanism 4 that provides a distinctive movement of the blade 21. The pull-cutting mechanism 4 is configured so that the blade 21 moves in the blade length direction (X direction) while cutting into the fence A, and basically cuts out a fillet a from the fence A with one sweep of the blade 21 per slice of one fillet a, and it is possible to set the cutting angle α between the blade length direction (X direction) of the blade 21 and the conveying surface 1a during one movement of the blade 21 along the blade length direction (X direction).

[0038] As shown in FIG. 7, a slice angle changing mechanism 5 is also used to change the slice angle (the second relative angle) θ2 between the blade width direction (Y direction) of the blade A and the conveying surface 1a.

[0039] When constructing the pull-cutting mechanism 4, the shape of the blade 21 is not limited; the cutting angle α and cutting edge length T are important. The cutting edge length T is the actual length of the blade 21 when projected onto the conveying surface 1a. In this embodiment, as shown in FIG. 4, a cutout groove 1c is provided on the conveying surface 1a, and the cutting edge portion 210 of the blade 21 partially penetrates into the groove to perform the pull-cutting. The cutting edge portion 210 is approximately linear at an angle and includes a cutting edge and a cutting edge boundary, similar to a typical Japanese knife. First, if the cutting angle α is small, the fillet a will be caught between the blade 21 and the groove 1c, making it difficult to cut. In addition, the cutting edge length T will be long, resulting in a larger system size. Furthermore, if the cutting angle α is large, the cutting edge length T can be shortened, but the resistance during cutting will be greater, causing the soft fresh salmon fillet A to move significantly in the direction of movement of the blade 21. For this reason, the setting of the cutting angle is important.

[0040] First, regarding the effectiveness of the cutout groove 1c, as shown in Figure 5(a), if there were no cutout groove and the tip of the blade came into contact with the conveying surface, not only would it scrape the conveying surface, but the reaction force Fa would reduce the vertical component of the force F applied to the fence during the cut, which is thought to affect the accuracy of the cut.In contrast, if the cutting edge of the blade is inserted into the groove to slice, the effect of the reaction force Fa is reduced and a sharp cut can be made.

[0041] Next, it is difficult to uniformly define the cutting angle α because the optimum angle varies slightly depending on the device configuration, the object to be sliced, etc. Therefore, in this embodiment, the relationship between the cutting angle α and the cutting edge length T shown in Figure 5(b) is expressed as follows, where L is the longitudinal dimension of the fillet, T is the cutting edge length, and T1 is the cutting edge effective length (the distance from the support point 44 to the end of the blade): T1>L T1=(T / 2)*(1 / cosα) Based on this, the cutting angle α and cutting edge length T are set.

[0042] When cutting the fence A with a pull cutter, it is effective to hold down the top and sides of the fence A and the front and sides of the fillet a in the direction of movement of the blade, as shown in Figure 6, with an appropriate holding mechanism.However, in order to prevent the fence A and fillet a from losing their shape when cutting with a pull cutter, it is important to hold them down so that deformation due to the force applied to them by the blade 21 does not occur as much as possible.

[0043] The pull-cutting mechanism 4 shown in Fig. 3 has a horizontal rail 41, which serves as a blade mounting section, that can be raised and lowered on a frame structure F consisting of a vertical frame f1 and a horizontal frame f2, and a blade holder 42 that can move along the horizontal rail 41. A flat blade 21, which serves as a blade, is rotatably held by the blade holder 42. The horizontal rail 41 can be raised and lowered by a lifting motor 40, which is a first driving means, the blade holder 42 can be moved on the horizontal rail 41 by a movement motor 43, which is a second driving means, and the cutting angle α of the flat blade 21 can be changed by a cutting angle adjustment motor 44, which is a third driving means, and these are controlled by the control unit 3 shown in Fig. 1.

[0044] The blade 21 shown in FIG. 4 has a cutting edge 210 that is diagonally and approximately linear, and the closer it is to the conveying surface 1a, the closer it is to the longitudinal starting end 210a (the side where cutting begins) and the closer it is to the longitudinal end 210c (the side where cutting ends). The dashed line indicates the opening position of the cutout groove 1c on the conveying surface 1a, and the groove bottom is below the dashed line. The cutting edge 210 near the end 210c enters the groove 1c but does not reach the groove bottom. The blade slides at a constant cutting angle α, cutting at the intermediate part 210b in the blade length direction and finishing the cut at the end 210c.

[0045] Regarding cutting with the middle part of the blade, for example, if the fulcrum P of the blade 21 is located at the midpoint of the cutting edge length T, if the cutting is performed behind the fulcrum P as shown in the right blade 21 in Fig. 5(c), the reaction force Fb from the object A to be sliced ​​acts in the direction of rotating the blade 21, thereby reducing the vertical and horizontal components of the force F applied to the object A, which is thought to affect the accuracy of the cutting stroke. In contrast, if the cutting is performed with the middle part MD set in a position leading the fulcrum P as shown in the left blade 21 in Fig. 5(c), the reaction force from the object A to be sliced ​​is received by the fulcrum P, which reduces the effect on the vertical and horizontal components of the force F applied to the object A, making it possible to perform a sharp cutting stroke.

[0046] 1 is configured to calculate parameters such as the positions of the start and end points where the blade 21 crosses the conveying path a, the cutting angle α of the blade 21, and the slicing angle θ2 for each fillet a (or for each fence A) based on information about the fence A to be sliced ​​acquired in advance by the camera 9 and information such as the dimensions required for the fillet a input from the setting unit 30, and to send control signals to the motors M1, 40, 43, 44, etc. The same applies to motor 51, which will be described later.

[0047] In this embodiment, as described above, the blade 21 has a cutting edge portion 210 that is obliquely and approximately linear, and is controlled to move approximately horizontally while maintaining a constant cutting angle α and with the vicinity of the terminal end 210c in the blade length direction (X direction) partially inserted into the cutout groove 1c. That is, when the blade 21 moves in Fig. 4, the cutting edge portion 210 enters the fence A from the middle portion 210b in the blade length direction, and slicing is completed at the position where the terminal end 210c in the blade length direction (X direction) crosses the fence A.

[0048] After slicing one fillet a, the control unit 3 raises the blade 21 via the motors 40, 41, and 43 to a position where it will not interfere with the fence A or the fillet a (the position shown by the dashed line in the figure), returns it to the home position, and then moves on to the slicing process for the next fillet a.

[0049] 7, the slice angle change mechanism 5 is configured so that the frame structure F that holds the blade 21 can rotate around a fulcrum n, and is driven by a slice angle adjustment motor 51, which is a driving means, in response to a command from the control unit 3. That is, in this embodiment, the pull-cutting mechanism 4 is assembled to the frame structure F, which is the movable part of the slice angle change mechanism 5.

[0050] At this time, the fulcrum n of the frame structure F is set so as to substantially coincide with the position of the cutting edge of the most lowered blade 21. Alternatively, the fulcrum n may coincide with the position of the cutout groove 1c.

[0051] The blade 21 repeats the above operation, for example, one second per slice, and cuts out a predetermined number of fillets a from the block A, completing the slicing operation for one block A.

[0052] As described above, the slicing device 2 of this embodiment uses a blade to sequentially slice the fences A that are transported on the transport surface 1a and are to be sliced, to cut out fillets a. It is provided with a pull-cutting mechanism 4 that moves the blade 21 in the blade length direction (X direction) while cutting into the fences A to cut out fillets a from the fences A. The pull-cutting mechanism 4 operates by moving the blade 21 along the blade length direction (X direction) as a basic operation when slicing one fillet a, and the cutting angle α between the blade length direction (X direction) of the blade 21 and the transport surface 1a during this operation can be set.

[0053] In this way, by moving the blade 21 in the blade length direction (X direction) at a certain cutting angle α, an action similar to that of a craftsman's pull-cutting can be realized. In other words, while limiting the area where the conveying surface 1a and the blade 21 are close to each other, it is possible to minimize deformation of the fence A and the fillet a due to the force applied to them from the blade 21, and to properly cut out the fillet a with a short stroke while preventing any uncut portions.

[0054] In this case, a cutout groove 1c is provided on the conveying surface 1a side, into which the vicinity of the terminal end 210c of the blade 21 in the blade length direction (X direction) enters. Even if the cutting edge 210 of the blade 21 enters, the actual cutting into the fence A starts near the middle 210b of the blade 21 in the blade length direction (X direction), and the fence A is cut off within the cutout groove 1c only when the terminal end 210c of the blade 21 in the blade length direction (X direction) passes. For this reason, the blade 21 does not scrape the conveying surface 1a, and the risk of the fillet a sinking into the cutout groove 1c can be reduced.

[0055] Specifically, the blade 21 has a cutting edge portion 210 that is diagonally and approximately linear, and by keeping the cutting angle α constant and moving the cutting edge portion 210 approximately horizontally while it is partially inserted into the cutout groove 1c, the blade enters the fence A from the middle portion 210b halfway in the blade length direction (X direction), and the slicing operation ends at the position where the terminal portion 210c crosses the fence A.

[0056] In this way, the cutting operation can be achieved by simply moving the blade 21.

[0057] In addition, this embodiment further includes a slice angle change mechanism 5 that changes the slice angle θ2 between the blade width direction (Y walk) of the blade 21 and the conveying surface 1a, and a pull-cutting mechanism 4 is provided on the frame F, which is the movable part of the slice angle change mechanism 5, so that the width dimension W of the fillet a can be set at the same time, and fillets a of an appropriate size can be cut out.

[0058] At that time, the cutting edge position when the blade 21 is at its lowest point becomes the fulcrum n for changing the slicing angle, so no matter what angle is changed, the position for cutting the bottom surface of the fence A remains unchanged, and it is possible to reliably prevent any part of the fence A from remaining uncut.

[0059] Although one embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment.

[0060] <Variation 1> For example, as shown in Fig. 8, the blade 21X may have a cutting edge portion 210X curved in a crescent shape, and the entire blade 210X may be rotated and moved in the blade length direction while being lowered. It is diagonally and approximately straight, and like a typical Japanese knife, it includes a cutting edge and edge boundary.

[0061] To achieve this, the cutting angle adjustment motor 44X is driven together with the movement motor 43X to change the holding angle of the blade holder 42X (i.e., the cutting angle α) during movement, and the linear guide 41X that guides the blade holder 42X is configured to gradually approach the conveyance surface. That is, when movement starts from the home position, the blade 21X descends obliquely while maintaining the cutting angle of 0° and approaches the fence A, and then begins to rotate so that the cutting angle α gradually deepens as it descends further obliquely from the cutting position, and near the end of the sliding cut, the terminal end 210cX of the cutting blade portion 210X enters the groove 1c as shown in Figure 9, and the sliding operation ends at a position where it crosses the fence A.

[0062] In this way, the cutting angle α is not set to a deep angle that would cause the fence A or the fillet a to move and become misaligned, and the above-mentioned presser foot is not required. Also, since the cutting can be performed by making the stroke of the blade 21X in the blade length direction (X direction) as small as possible, it is possible to miniaturize the system.

[0063] The linear guide 41X rotates through the return section, and when the blade 21X returns from the cutting end position, the blade 21X is lifted up so that it can return to the home position without coming into contact with the fence A.

[0064] <Variation 2> In Figure 10, instead of a motor for adjusting the cutting angle, a support shaft 301 set at one end of the blade length of the blade 21Y is rotatably supported by a slider 302, and a shaft 303 set at the other end is slidably engaged with a fixed guide portion 304. By moving the support shaft 301, the shaft 303 is gradually guided diagonally downward, and the cutting angle α of the blade 21Y deepens as it slides.

[0065] With this configuration, the motor for moving the slider 302 can also serve as the motor for adjusting the cutting angle, which simplifies the control.

[0066] <Variation 3> The slicing device shown in FIG. 11 is an example in which a slicing angle changing mechanism 405 is provided on a frame F4, which is a movable part of a pulling and cutting mechanism 404, thereby reducing the total weight of the tilting object.

[0067] Here, the movable part of the pull-off mechanism 404 is composed of a first frame 441 that supports the fulcrum n of the slice angle change mechanism 405, and a second frame 442 that has an arc-shaped guide part 442a that supports the rotation circumference of the slice angle change mechanism 405, and these frames 441, 442 are supported together on the linear guide 400 so that they can move back and forth.

[0068] The slice angle change mechanism 405 mainly comprises a blade fixing frame 451 whose base end 451a is supported by a motor M4 attached to the fulcrum n of the first frame 441 and whose rotating end 451b is engaged with a guide portion 442a of the second frame 442, and the blade 21 is fixed to this blade fixing frame 451.

[0069] According to this, when changing the slice angle, it is only necessary to tilt the blade fixing frame 451 and the blade 21, and there is no need to tilt the frames 441, 442 of the pull-cutting mechanism 404, etc., so the total weight of the tilting object is lighter, the slice angle control time is shortened, and ultimately the cycle time required for slicing can be shortened.

[0070] Here too, the axis m of the motor M4 and the position of the cutting edge portion 210 or the cutout groove 1c are aligned, making it possible to avoid interference of the cutting edge portion 210 with the drawing groove 1c while minimizing the cutout groove width.

[0071] Other configurations can also be modified in various ways without departing from the spirit of the present invention. [Explanation of symbols]
