Description

[Technical Field]

[0001] The present invention relates to a conveying device for an object to be sliced, which is particularly useful for cutting fillets for sushi from food, particularly fillets 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 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 automation of sushi topping processing has not progressed is that it is not enough to simply make the weight of the fillets the same as with sliced frozen fish or sashimi; when the soft fillets are placed on top of the rice, they bend to cover it, so unlike sashimi, they need to be sliced to a fixed size, with relatively large length and width dimensions compared to the thickness of the fillets.

[0007] That is, while fish bodies vary in size, as shown in Figures 12(a) and (b), if cutter b is normally inserted into fence A, that is, cut at a right angle to the length of fence A, the longitudinal dimension L of the fillet a may not be enough for the required sushi size. In such cases, the cutting method must be changed depending on the shape of fence A, but this type of sushi material processing relies solely on the skill of a craftsman, and until now, such craftsmanship has not been realized by machine.

[0008] Therefore, as shown in FIG. 12(c), it is conceivable to mechanically change the slice angle θ formed by the blade length direction X of the blade b and the direction V of the fence A, which is the object to be sliced.

[0009] In this way, even if the longitudinal dimension L of the fillet a cut off at a right angle is less than the size required for the fillet a (longitudinal dimension L0) due to an insufficient width of the fence A, the fillet a can be cut out to the specified dimension L0 by cutting it off at an angle.

[0010] However, when employing such a method, a particular problem arises when the object to be sliced is a very soft fillet A, such as fresh salmon.

[0011] To realize the above-mentioned slicing device, as shown in Figure 13, it is conceivable to use a belt conveyor 100 to transport the fence A, and rotate the entire belt conveyor 100 from (a) to (b) while the fence A is still on the belt conveyor 100. However, the belt conveyor 100 does not reach the areas of the belt conveyor 100 that are far from the blade passing line CL (gap S in the figure), so the fence A is not supported from below, and the tip of the soft fence A hangs down into the gap S, preventing it from reaching the blade passing line CL, making slicing difficult. In particular, in this state, it is difficult to reliably cut the grain and skin of the fence A.

[0012] 14, it is conceivable to leave the belt conveyor 100 as it is and apply a pressing force to the side A1 of the fence A using some kind of pressing mechanism 200 to adjust the angle of the fence in the yaw direction (the horizontal direction perpendicular to the conveying direction) as shown in (a) → (b) on the belt conveyor 100. However, with this method, if the fence A is soft, the shape of the fence A will be deformed.

[0013] The amount of yaw angle adjustment θ of fence A can be determined from the shape of fence A measured in advance by some means, but if an external force is applied to fence A to adjust the angle θ, fence A will be deformed from its measured state, making it difficult to achieve an appropriate fixed-width slice.

[0014] The present invention has been made with a focus on these problems, and aims to realize a new slicing object conveying device that can adjust the relative angle of the object to be sliced, particularly for soft objects such as fillets of fresh fish, and can reliably convey the object to near the blade passing position line, and can perform the angle adjustment without deforming the object to be sliced. [Means for solving the problem]

[0015] In order to achieve the above object, the present invention takes the following measures.

[0016] In other words, the slicing object conveying device of the present invention is used to sequentially slice the slicing object conveyed on a conveying path with a blade and cut out fillets with a longitudinal dimension along the blade length direction from a fence, and is characterized in that it has a slice angle changing unit that changes the slice angle between the blade length direction of the blade and the direction of the slicing object, and is configured to be able to change the relative conveying angle of the conveying path main body with respect to the blade passing line while maintaining a predetermined gap between the blade passing line along which the blade passes and the end of the conveying path main body adjacent to the blade passing line.

[0017] In this way, even if the conveying angle of the slicing object is changed, the conveying path main body can reliably convey the slicing object close to the blade passing line. Moreover, because the conveying angle of the slicing object can be changed without forcibly pressing the slicing object, deformation of the fence can be prevented even if the slicing object is a soft fence.

[0018] In a specific embodiment, the conveying path main body comprises a start pulley row in which multiple start pulleys are arranged, a terminal pulley row in which multiple terminal pulleys are arranged, and a conveying surface consisting of a collection of wire belts wound between the start pulleys and the terminal pulleys, and the slice angle change unit is configured to allow the angle of the conveying surface to be changed relative to the blade passing line, and to cause each terminal pulley to follow with a swinging motion while maintaining a predetermined gap between the terminal pulley row and the blade passing line as the angle is changed.

[0019] In this way, the filament belt can transport the object up to just before the blade passing line, and the transport surface simply changes angle while the object is placed on top, so the object is not forcibly pressed.

[0020] In this case, if the slice angle change unit is configured so that the starting pulley row and the conveying surface are integrated and rotate relative to the ending pulley row, then simply by setting the rotation axis, the starting pulley row and the conveying surface can be rotated appropriately, and the angle of the object to be sliced can be changed.

[0021] Alternatively, if the slice angle change unit is configured so that a blade groove forming member is provided on the blade passing line and the blade groove forming member and the terminal pulley row are integrated and rotate relative to the conveying surface, the slice angle can be changed simply by rotating the blade groove forming member, which is effective in cases where there are conveying surfaces on both the upstream and downstream sides of the blade passing line.

[0022] Another embodiment of the present invention is one in which the conveying path main body is provided with a blade groove forming member on the blade passing line, and the end of the conveying path main body is overlapped with the blade groove forming member so that it can rotate relatively.

[0023] In this way, the object to be transported slides on the upper surface of the blade groove forming member at the transition section between the main conveying path and the blade groove, but if the sliding resistance at this section is kept below the allowable value, no gap will be created between the end of the main conveying path and the blade groove, and the angle can be changed without forcibly pressing the object to be transported.

[0024] More preferably, the slice angle change unit further includes a speed adjustment mechanism, and the speed adjustment mechanism is configured to interpose a third pulley midway along the return path of the filament belt that is wound around the starting pulley and the ending pulley and rotates in the forward and return paths, and to maintain a constant rotational speed of each filament belt by changing the distance of the return path in accordance with changes in the conveying distance of the filament belt on the forward path as the starting pulley row and the ending pulley row rotate relative to each other.

[0025] When there is a change in the conveying distance of the wire belts wound around each pulley on the outward path, the tension between each wire belt becomes uneven, which causes the object being conveyed to change position and the lifespan of the wire belts to vary, making parts management difficult.However, the above-mentioned configuration can effectively solve these problems. [Effects of the Invention]

[0026] According to the present invention as described above, it is possible to provide a new slicing object conveying device that can adjust the relative angle of the fence, particularly for soft slicing objects such as fresh fish fences, to reliably convey the object close to the blade passing position line, and that can perform the angle adjustment without deforming the object.

DETAILED DESCRIPTION OF THE INVENTION

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

[0029] FIG. 1(a) shows a slicing system SS for sushi toppings that incorporates a slicing object conveying device TD according to this embodiment. This slicing system SS is designed to automatically cut sushi-sized fillets from fillets A obtained from fresh fish. The fillets A in this embodiment are, for example, fresh salmon that has been filleted and processed into blocks. Of course, the type of fish that becomes the fillets A to be sliced is not limited to salmon (fresh salmon), and the process for obtaining the fillets A is not limited to filleting.

[0030] The conveying path 1, which forms an endless track, is driven by a motor M1, and the fence A placed on the conveying surface 1a is conveyed in the direction of the arrow V0 towards the slicing section 2, where it is sliced. Every time the slicing section 2 operates and cuts out a fillet a, the conveying path 1 intermittently feeds the fence A by an amount equivalent to the thickness of the fillet a, in preparation for slicing the next fillet a. Control of the motor M1 and the slicing section 2 is managed by a 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 data. The CPU sequentially reads the programs and works with peripheral hardware resources to execute various controls in this embodiment.

[0032] In the slicing section 2, a blade 21 is arranged so that a direction intersecting with the conveying direction V of the conveying path 1 is a blade length direction (blade length direction) X.

[0033] As shown in Figures 1(b), 2(a) and (b), a slice angle change unit 4 is provided to change the slice angle θ formed between the blade length direction X of the blade 21 and the direction (conveying direction) V of the fence A, which is the object to be sliced.

[0034] When changing the slice angle, a camera 5 that photographs the fence A is installed on the transport path 1 shown in Figure 1, and the image captured by the camera 5 is input into the control unit 3, where information regarding the dimensions and orientation of the fence A is collected.

[0035] On the other hand, the slice angle change unit 4 is configured so that even if the conveying direction V of the fence A, which is the object to be sliced, is changed, as shown in Figure 2(a) → (b), a predetermined gap Δ is maintained between the blade passing line CL along which the blade 21 passes and the end 10a of the conveying path main body 10 (i.e., so that they do not separate), and the conveying angle θ (slice angle θ) of the conveying path main body 10 relative to the blade passing line CL can be changed without pressing the side A1 of the fence A.

[0036] Specifically, the conveying path main body 10 is made up of a plurality of conveying lines 10L. Each conveying line 10L has a round belt 13a, which is a linear belt, wound between a start pulley 11a and a terminal pulley 12a, and a conveying surface 13 made up of a collection of the plurality of round belts 13a is formed between the start pulley row 11 and the terminal pulley row 12.

[0037] Of course, the filament belt is not limited to a round belt, but may be a V-belt, a flat belt, or the like.

[0038] The start pulley 11a is axially mounted around a common axis m1 between the vertical frames 41, 41 of the movable frame 40, which is made up of vertical and horizontal frames 41, 42. The movable frame 40 is configured to rotate horizontally together with the start pulley row 11 around a fulcrum n1 located near the center of the width direction, slightly toward the blade passing line CL from one of the horizontal frames 42. Here, the individual start pulleys 11a are integrated as a whole to form the start pulley row 11. The slice angle θ of the slice angle change unit 4 is input to the motor M2 as a command from the control unit 3 (see Figure 1), and is realized by the motor M2 rotating the movable frame 40. A conveying force is applied to the start pulley 11a from the motor M1.

[0039] As shown in Fig. 3(a), the terminal pulley row 12 is mounted on a fixed frame 60 arranged facing the blade passing line CL along which the blade 21 passes. As shown in Fig. 3(b), a holder 62 is rotatably attached to the fixed frame 60 via an upright rotating shaft 61, and each terminal pulley 12a is rotatably attached to the holder 62 via a substantially horizontal shaft m2. The rotation of each terminal pulley 12a on the rotating shaft 61 and the rotation in the belt feed direction are not linked to each other.

[0040] 2 rotates from (a) to (b), the distance between the start pulley 11a and the end pulley 11b of each conveyor line 10L increases the farther it is from fulcrum n1. If the round belt 13a is simply wound between the start pulley 11a and the end pulley 11b, a uniform tension is applied to the round belt 13a when it is not rotating as shown in FIG. 2(a), but the tension and circumference of each round belt 13a when it is rotating as shown in FIG. 2(b) become uneven.

[0041] Specifically, the farther the start pulley 11a is from the end pulley 12a, the greater the tension applied to the round belt 13a and the longer its circumference becomes. However, because the rotation speed of the start pulley 11a, which applies a conveying force to the round belt 13a, is constant, the fence A cannot be conveyed straight in the conveying direction.

[0042] Therefore, the slice angle change unit 4 is provided with a speed adjustment mechanism 7 shown in Figure 4 to maintain constant rotational speed and tension of the round belt 13a. The speed adjustment mechanism 7 includes an upper outgoing path 10L1 and a lower returning path 10L2 that make up each conveyor line 10L. The speed adjustment mechanism 7 includes a third pulley 71 interposed midway along the returning path 10L2. Each third pulley 71 is individually supported by the movable frame 40 via an arm 72, which is tensioned by a return spring 73. When the movable frame 40 rotates, the conveying distance of the round belt 13a, which is wound between the start pulley 11a and the end pulley 12a, on the outgoing path 10L1 increases. This causes the arm 72 to rotate, moving the position of the third pulley 71 closer to the outgoing path 10L1 and reeling out the round belt 13a on the returning path 10L2 toward the outgoing path, thereby maintaining constant rotational speed and tension.

[0043] 4(b), the initial position of the arm 72 should be perpendicular to the conveying surface (position A) or tilted toward the slicing side (for example, position B). If the arm 72 is positioned closer to the loading side (for example, position C), the pulley 71 must overcome position A, which may result in unstable speed and tension adjustments.

[0044] Data Z relating to specifications such as a predetermined dimension LO (a width dimension required in advance for the fence A) is input to the control unit 3 shown in FIG.

[0045] FIG. 5 is a flowchart showing an outline of the control performed by the control unit 3 in this embodiment.

[0046] When a fence A to be sliced is inserted (step S1), the fence A is photographed by the camera 5 (step S2), and the shape of the fence A is acquired (step S3). For example, in the case of a fence A of fresh salmon as shown in Fig. 6, slicing starts from a leading position near the head (located on the left side in the figure) to a terminal position near the tail (closer to the right side in the figure). At which slicing position should the blade 21 be rotated by how many degrees to ensure a predetermined dimension L0 with respect to the width L of the fence A? The rotation amount of the fence A is determined in relation to the feed amount of the fence A (step S4) and stored in advance.

[0047] Then, the fence A, which is the object to be sliced, is rotated (step S5), and the fence A, which is the object to be sliced, is transported (step S6). When the fence A reaches a predetermined position, the blade 21 is actuated to slice the fence (step S7). Of course, step S5 also includes the case where the amount of rotation is 0.

[0048] The sliced fillets a are carried out by a carrying-out mechanism 100 such as a separate conveyor provided at a position beyond the blade passing line CL, as shown in FIG. 1 (step S8).

[0049] Normally, about 50 fillets a can be taken from fence A, but the number of fillets that can be taken from fence A is calculated in the first photograph and calculation, and the number of slicing operations is counted to determine whether slicing is complete (step S9).

[0050] If the answer is NO in step S9, it is determined whether rotation is required for the next slice (whether the slice angle needs to be changed) (step S10). If the answer is NO, the process returns to step S6 with the current amount of rotation, whereas if the answer is YES, the process returns to step S5 and starts from rotating the object to be sliced.

[0051] If the answer is YES in step S9, the slicing process ends (step S11).

[0052] In this way, it is possible to continuously and appropriately cut out fillets a of a predetermined dimension L0 from the rail A as shown in FIG.

[0053] As described above, the slicing object conveying device of this embodiment is used to sequentially slice the slicing object, i.e., the fence A, conveyed on the conveying path 1, with the blade 21 to cut out fillets a having a longitudinal dimension L along the blade length direction (X direction) of the blade 21 from the fence A, and has a slice angle changing unit 4 that changes the slice angle θ between the blade length direction (X direction) of the blade 21 and the direction (V direction) of the slicing object, i.e., the fence A.

[0054] This slice angle change unit 4 can change the relative conveying angle θ of the conveying path main body 10 with respect to the blade passing line CL without pressing the side A1 of the fence A, simply by applying a posture changing force from the conveying surface 13 to the bottom surface of the fence A, while maintaining a predetermined gap Δ between the blade passing line CL along which the blade 21 passes and the end 10a of the conveying path main body 10 adjacent to the blade passing line CL.

[0055] In this way, even if the conveying angle θ of the fence A, which is the object to be sliced, is changed, the conveying path main body 10 can reliably convey the fence A close to the blade passing line CL. Moreover, because the conveying angle θ of the fence A can be changed without pressing the side surface A1 of the fence A, deformation of the fence A can be effectively prevented even if the fence A is soft, such as fresh salmon.

[0056] Specifically, the conveying path main body 10 comprises a start pulley row 11 in which a plurality of start pulleys 11a are arranged, a terminal pulley row 12 in which a plurality of terminal pulleys 12a are arranged, and a conveying surface 13 consisting of a collection of wire belts 13a wound between the start pulleys 11a and the terminal pulleys 12a, and the slice angle change unit 4 is configured to allow the angle of the conveying surface 13 to be changed relative to the blade passing line CL, and as the angle is changed, each terminal pulley 12a is caused to follow with a swinging motion while maintaining a predetermined gap Δ between the terminal pulley row 12a and the blade passing line CL.

[0057] In this way, the filament belt 13a can transport the fence A up to just before the blade passing line CL, and the transport surface 13a simply changes its angle while the fence A is placed on it, so it does not press against the side A1 of the fence A.

[0058] In particular, the slice angle change unit 4 is configured so that the starting pulley row 11 and the conveying surface 13 are integrally rotated relative to the terminal pulley row 12, so that simply by setting a rotation axis n1 on the movable frame body 41 and driving it, the starting pulley row 11 and the conveying surface 13 can be rotated appropriately and the angle of the fence A can be changed.

[0059] Furthermore, the slice angle change unit 4 is equipped with a speed adjustment mechanism 7, which has a third pulley 71 interposed in the middle of the return path 10L2 of the filament belt 13a, which is wound around the starting pulley 11a and the ending pulley 12a and rotates in the outgoing path 10L1 and the return path 10L2, so that the rotational speed of each filament belt 10a is kept constant by changing the distance of the return path 10L2 in accordance with changes in the conveying distance on the outgoing path 10L1 of the filament belt 13a as the starting pulley row 11 and the ending pulley row 13 rotate relative to each other.

[0060] Therefore, even if the conveying surface 13 shown in Figure 2 rotates from (a) to (b), the tension and circumference of each round belt 13a are always constant, which eliminates the adverse effect on the conveying direction of the fence A, and also makes the lifespan of the round belts uniform, making parts management easier.

[0061] 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.

[0062] For example, in the above embodiment, the fulcrum n1 was set at the center in the width direction of the movable frame 41, so it was possible to accommodate whether the movable frame 40 rotated to the left or right, but if the main rotation was to the left, for example, the fulcrum n1 could be set near the tip of one of the vertical frames 41 as shown in Fig. 7. The same applies when the main rotation was to the right.

[0063] <Variation 1> Alternatively, in the slice angle changing unit 4 of the above embodiment, the conveying surface 13 side is rotated, but as in the slice angle changing unit 104 of Figures 8 and 9, a blade groove forming member 8 for forming a groove for receiving the blade 21 on the blade passing line CL may be provided, and the blade groove forming member 8 may be rotated relative to the conveying surface 13 integrally with the terminal pulley row 12.

[0064] The cutting groove forming member 8 is in the form of a movable frame that can rotate around a fulcrum n2, and a holder 82 is rotatably attached to a movable frame portion 80 of the cutting groove forming member 8 with a rotation shaft 81 standing upright, and each of the terminal pulleys 12a is rotatably attached to the holder 82 via a substantially horizontal shaft m2. The rotation of each of the terminal pulleys 12a on the shaft m2 and the rotation in the belt feed direction themselves are not linked to one another.

[0065] Then, by rotating the movable frame portion 80 of the cutting groove forming member 8 around the fulcrum n2, the cutting line CL is inclined with respect to the moving direction (X direction) of the fence A, and the fence A is cut obliquely.

[0066] In the example of Figure 8, a discharge conveying path 1' is also provided downstream of the blade passing line CL, consisting of a starting pulley row 11', a terminal pulley row 12', and a conveying surface 13' made of a round belt, and pulley 11a' of the starting pulley row 11' has a swivel structure similar to that of the terminal pulley 12a of the upstream conveying path 1.

[0067] In this way, the slice angle of the fence A relative to both conveying surfaces 13, 13' can be changed simply by rotating the cutting groove forming member 8 together with the slicing section 2 while keeping the upstream conveying surface 13 and the downstream conveying surface 13' fixed, which is effective when it is not desired to rotate the conveying surfaces 13, 13'.

[0068] <Variation 2> Also, as shown in Figures 10(a) to (c), the slice angle change unit 204 may be provided with a blade groove forming member 208 having a groove 208a on the blade passing line CL, and the end 10a of the conveying path main body 10 may be configured to overlap the blade groove forming member 208 and be able to rotate relatively.

[0069] In this example, the conveying path main body 10 includes a start roller 10m, a finish roller 10n, and a belt conveyor 10r that rotates between the rollers 10m and 10n. On the other hand, the cutting edge forming member 208 is an inverted L-shaped member whose width is larger than that of the belt conveyor 10r, and the end of the belt conveyor 10r is located under the horizontal portion of the cutting edge forming member 208.

[0070] In this way, at the transition point between the belt conveyor 10r of the conveying path main body 10 and the groove 208a, the fence A, which is the object to be conveyed, slides on the upper surface 281 (the surface that comes into contact with the fence A) of the horizontal part of the blade groove forming member 208, and if there is no problem with the sliding resistance here, it is possible to realize the function of not creating a gap between the end 10a of the conveying path main body 10 and the groove 208a and changing the angle without pressing on the side of the fence A.

[0071] In cases where there is a problem with sliding resistance, in order to smoothly transport the fence A when it passes through the blade groove forming member 208 from the transport surface, a slope 281a may be provided on the upper surface 281 of the horizontal part on the loading side of the blade groove forming member as shown in Figure 10(d).

[0072] In this case, if a belt conveyor 10r is used with protrusions or the like on its surface and a recess or the like is provided at the corresponding position on the cutting groove forming member 208 to receive the protrusions, the conveying accuracy can be improved when the fence A rides on the cutting groove forming member 208.

[0073] <Variation 3> Furthermore, as shown in Figure 11, when overlapping the conveying path main body 10 with the blade groove forming member 308 having a groove 308a on the blade passing line CL, the conveying path main body 10 may be composed of a start pulley 311a, a end pulley 312a, and a round belt 313a, as shown in Figure 2, and the end pulley 312a may be integral with the blade groove forming member 308 and be swivelable, so that the end of the round belt 313a overlaps the blade groove forming member 308.

[0074] In this way, the distance that the fence A slides on the cutting groove forming member 308 can be minimized or eliminated as compared with the case of the belt conveyor 10r shown in FIG.

[0075] To achieve this, when the edge of the groove of the cutting groove forming member is L3 and the end of the conveying section is L4 with respect to the blade passing line CL, the end of the conveying section is arranged so that it can be seen from the groove edge. Distance between CL and L3 > Distance between CL and L4 (Δ in Figure 2(b)) It is recommended to set it to .

[0076] Other configurations can also be modified in various ways without departing from the spirit of the present invention. [Explanation of symbols]
