Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for making fish fillets by which fish of any size and shape can be cut at a predetermined angle and size.

Conventionally, in this type of fish filleting method, it is extremely difficult to cut frozen fish and raw fish with the same device. For example, a vertically vibrating blade is used for frozen fish, and a rotary round blade is used for raw fish. In many cases, it was necessary to provide a separate cutting device, resulting in a lot of waste. In addition, especially when using a rotary blade to cut raw fish, the cutting blade frictionally pulls the fish flesh under pressure in the direction of rotation of the blade, making it difficult to cut as the fish escapes and the position of the fish also shifts, making it difficult to cut accurately. This is difficult, especially when the cross-sectional structure of the fish body is complex, and the deviation is significant, making it impossible to completely separate the fish body. Furthermore, when the rotary blade is a saw blade, the fish body vibrates back and forth, making it impossible to obtain a smooth cut cross section and also causing tissue destruction on the surface layer of the cross section, causing problems in terms of appearance and taste. It also had In addition, the size and cross-sectional inclination angle of the obtained fillets are often constant or simple even if they can be changed, so we invented a method to automatically obtain good-looking fillets that increase the commercial value of the fish. This has been a long-standing issue in the industry.

The present invention was developed in consideration of the above situation, and by cutting the fish body with a long blade that advances while reciprocating horizontally in the width direction, it is possible to cut both frozen fish and raw fish, and it can also be cut in any size and at any inclination angle. The purpose is to provide a method to easily obtain good-looking fillets by making it possible to cut the fish at any angle. A stopping means and a cutting means capable of cutting the fish at an arbitrary inclination angle are provided, and the fish is transferred to an appropriate position by the holding means and fixed by the conveying means,
The cutting means has a long blade placed at an appropriate location, and while moving it forward toward the fish body, repeats horizontal reciprocating motion in a direction perpendicular to the forward direction several times to cut and separate the fish at an appropriate inclination angle, and then retreat the long blade. Then, the long blade is released from the fish body, and the locking means is released from the fish body.Then, the fish is moved forward in appropriate pitches by the conveying means to complete the process of making one fillet, and the above process is repeated an appropriate number of times. It is characterized by the fact that it is made from a large number of fillets.

Next, a detailed explanation of the fish fillet preparation method according to the present invention will be explained using FIG. In the figure, a is a conveying means, b is a locking means, c is a cutting means, and e is a fish body. Any device can be used as the conveying means a, as long as it is easy to start and stop and can be transferred in pitch as appropriate, and the width of the conveying means a is determined depending on the size of the fish to be placed and the number of fish to be arranged in parallel. good. The locking means b is used to stably place the fish e in a predetermined position so that the fish e does not shift due to the movement of the blade during cutting. At the same time, there are methods of holding the fish body by placing a retaining wall in contact with the head, or applying appropriate pressure to the fish body with a flat plate or curved plate, but especially when the fish is raw, the fish body can be held. It is preferable to use a locking means that applies pressure evenly to the entire fish body so as not to damage the surface layer. Furthermore, the cutting means c has a long blade c1 that is elongated in the width direction of the fish body, and has a structure that allows it to horizontally reciprocate in the width direction of the fish body and move forward at an inclination angle with respect to the cutting location. The angle and forward speed can be set appropriately depending on the hardness and surface condition of the fish body to be cut.

To create fish fillets using the above method, proceed as follows. When one or more frozen fish or raw fish are placed side by side on the transport means a with the head toward the front in the direction of travel, a transport start signal is automatically or manually transmitted to the transport means a, and the transport means a The operation is started, the fish body e is transferred to the initial position for cutting, and the operation is stopped. This initial position differs depending on the shape of the fish body, and for example, the position will be different depending on whether the fish is a whole body, a half body fish, or a fish whose head has been cut off. Next, the fish body e stopped at a predetermined position is appropriately moved by the locking means b.
It is locked with a gap that the long blade c1 can cut into. When the fish body e is locked, the cutting means c is started automatically or manually, and after setting the long blade c1 to a predetermined cutting angle, the cutting means c is cut into the fish body e while making a reciprocating forward movement at a speed suitable for the fish body properties. . At this time, the long blade c1 makes a horizontal reciprocating motion while pressing the fish e, so the fish e moves due to frictional traction by the long blade c1, and the placement position of the fish e is temporarily shifted. Since c1 is reciprocating, the fish body e is followed by the subsequent movement in the opposite direction and is shifted, so that it almost returns to the predetermined position. When the long blade c1 completely cuts and separates the fish body, after retreating the long blade c1 to the rear of the fish body and extracting it from the fish body e,
It is then stopped at a predetermined position in preparation for cutting the next location. When cutting a single fillet, the long blade repeats its horizontal reciprocating motion multiple times, but the specific number of times depends on the type and size of the fish to be cut, as well as the degree of hardness of the fish meat. Set as appropriate. In the method according to the present invention, the fish body e is cut by the long blade c1 that reciprocates horizontally, so even if the fish body is wide, it can be completely cut off without leaving a part uncut unlike a rotary blade. Even when a plurality of fish bodies are arranged side by side and cut at the same time, it is possible to easily cut them without having to pay attention to the addition of blades or the positional relationship. While the long blade c1 is in a standby state above the fish body while stopping or continuing its reciprocating motion, the locking means b is released from the fish body e, and in synchronization with this, the conveying means a is moved forward by an appropriate pitch to move it to the next position after the fish body e. After the cut point is moved to a predetermined position, the fish body e is locked again to prepare for the cut by the long blade c1. During this time, the angle at which the cutting means c cuts into the fish body e is adjusted manually or automatically. It is preferable to change the cutting angle between the head and the tail so that the cutting angle becomes larger. Once the cutting angle is set, the long blade c1 can be advanced to cut into the fish body e, as described above. The above-mentioned connecting operations of each means are repeated until the entire length of the fish body is cut off, and the fish body e that has been cut over its entire length is completely unlatched, transferred to the outside by the conveyance means a, and taken out by appropriate means. , and will be provided for the next processing step. In addition, when cutting, if a plurality of fish bodies are arranged not only in the width direction but also in the length direction, it is possible to cut the fish bodies continuously, and further efficiency can be achieved. becomes.

Next, a detailed description will be given of a specific device for carrying out the present invention. FIG. 2 is a perspective view showing the main parts of a fish fillet manufacturing apparatus embodying the present invention. The fish fillet manufacturing apparatus connects a fish feeding device at the front stage and various processing devices at the rear stage to perform a series of processing steps. It is used to form a fish body or to be used as a single unit, and is equipped with a transport device A that transports fish bodies at a constant speed and arbitrary pitch, and a water-resistant and corrosion-resistant manaita device D, etc. is placed on the top. Furthermore, a fish holding device B is provided opposite to the transport device A to move up and down in synchronization with the movement of the transport device A to appropriately press and hold the fish E, and also to hold the fish E held under pressure at a predetermined inclination angle. It is constructed by providing a cutting device C for cutting and separating in the width direction. The conveyance device A carries the fish body E, which is the object to be cut,
This is for transferring the open end of the fish holding device B to the lower part of the cutting device C at arbitrary pitches in conjunction with the vertical movement, and for example, in the illustrated embodiment, it is composed of an endless rotating chain conveyor; The sprocket wheel A2 axis extends through the side plate A5, and the driving wheel A3 is fixed to the axis, and a drive source (not shown) disposed at the bottom of the device, such as an electric motor, is connected via a belt A4, etc. rotational force is transmitted. In addition, the side plate A5 is arranged in parallel so that a manaitor device D which is optionally placed on the upper part can be slid, and a guide guide guides the trajectory of the manaitor device D when the manaitor device D moves forward with the rotation of the chain conveyor A1 at the lower part. The width is set so that The chain conveyor A1 can also be mechanically or electrically controlled by a control unit provided outside or inside the conveyor A. For example, in this embodiment, the chain conveyor A1 can be controlled mechanically or electrically by a control unit provided outside or inside the conveyor A. By arranging one or more proximity sensors magnetically coupled to the transport path side plate A5, it is possible to manage the position of the fish on the transport device. In addition, although not shown, a reverse rotation mechanism is provided to the chain conveyor A1 so that the manaiter device D that has passed through the device and reached the terminal exit can be automatically reinstalled at the start end entrance, and the lower part is provided with a return path for the manaitor device. It is also possible to optionally include a roller conveyor, and it is also possible to use a belt conveyor instead of the chain conveyor A1.

As shown in FIGS. 2 and 3, the fish holding device B is installed close to the cutting device C, which will be described later. For example, in the illustrated embodiment, it consists of a front holding part 10 and a rear holding part 11, both of which are made of flexible and corrosion-resistant material such as stainless steel or hard plastic. It is constructed as a set of adjacent separation pieces 1 and 2 formed into vertically long flat plates. The separation piece 1 of the front holding part 10 increases the contact area with the surface layer of the fish body, and also increases the pressure force in the vertical direction.
In order to stably hold the fish body, the middle part is bent upward, and the distal end part is further bent upward to prevent the fish from being scratched by protrusions on the surface layer of the fish body. In addition, one end of each separation piece 1, 2 is connected to the supporting rod 4a, 4b with a communicating shaft, and the other end is left open so that it can be moved up and down individually according to the shape of the fish body, without destroying the structure of the fish body. In addition, it is configured to have an appropriate pressing force so that the fish body does not follow the movement of the cutting blade, and can wrap and hold the fish body E from the upper part. Furthermore, each separation piece 1, 2 has a beveled leading edge to prevent it from getting caught on the surface of the fish body, and also to prevent the fish body E which is enclosed and held.
In order to more securely fix the holder, substantially hemispherical small protrusions 3a and 3b are provided on the lower surface of the open end. Further, the support rods 4a, 4b are provided with side casing togs 12a,
12b, and the supporting rods 4a, 4b are rotatably attached to the side casings 12a, 12b.
It extends through and has slide grooves 8a, 8b and is fixed at right angles to arms 5a, 5b which are arranged opposite to each other. Further, the arms 5a, 5b are provided with slide grooves 8a, 8b for one end of the pistons 6a, 6b of the cylinders 7a, 7b fixed to the side casings 12a, 12b, in order to apply appropriate rotational force to the support rods 4a, 4b. The front holding part 10 and the rear holding part 11 can be pressed onto and released from the fish body E by loosely engaging the front holding part 10 and the rear holding part 11.

Further, as shown in FIG. 4, the cutting device C moves forward and cuts the fish body from the rear in the direction of travel while horizontally reciprocating in the width direction and cuts the fish body, and the cutting angle of the cutting part C1 into the fish body is determined based on the control signal. For example, in the illustrated embodiment, the configuration is as follows.

The cutting section C1 includes a movable cutting section C1' which moves forward while horizontally reciprocating the long blade 25, and a movable cutting section C1.
1' from the side and supports the inclination of the movable cutting section C1' when changing the cutting angle of the long blade 25 into the fish body.The movable cutting section C1 ' is mainly composed of a pedestal 21, a support 22, a slide plate 23, and a long blade mount 24 stacked vertically, and the pedestal 21 and support 22 are fixed together with screws etc. 23, the long blade mounting base 24 is fixed and integrated, and the bottom surface of the support base 22 has a long blade 25
A dovetail groove 61 is carved in the vibration direction of the slide plate 2.
A raised part 62 that engages with the dovetail groove 61 is provided on the upper surface of the blade 3 so that the long blade mount 24 can slide toward the fish body with respect to the pedestal 21. Incidentally, the long blade mount 24 and the pedestal 21 are slidably engaged by the dovetail groove 61 and the raised portion 62 slidably interlocking, and the long blade mount 24 vibrates at a high speed with respect to the pedestal 21. Although a lubricant or the like is applied to the contact surfaces and occlusal surfaces between the two, a member whose surface has been treated to prevent heat generation and wear may be interposed. Long blade mounting stand 24
is opened in a U-shape with respect to the direction of movement of the fish body, and a long blade attachment mechanism is provided at the tip of the opening, and in this embodiment, the structure is as follows. One tip 50b of the opening is cut out stepwise, and a protrusion 28b is provided so that the long blade 25 can be fixed by fitting into the attachment hole 38b provided at the end of the long blade.
After installing the long blade 25, remove the plate 26b from above.
By crimping the long blade 25, one end of the long blade 25 is clamped and fixed. Furthermore, as shown in FIG. A tension member 27 having a protrusion 28a on the upper surface and a threaded portion 31 protruding in the length direction of the long blade 25 is loosely fitted into the recess 44 so as to be slidable in the length direction of the long blade 25. The portion 31 is configured such that the long blade 25 can be tensioned and fixed by tightening a nut through a washer 43 having a diameter larger than that of the side portion of the recess 44 . At this time, the tension member 27 has the protruding end surface of the threaded portion 31 inside the side surface of the tip portion 50a, and the washer 43 is placed in close contact with the side wall of the tip portion.
Since the long blade 25 is also fitted with a gap 46 in the inner wall of the tip portion 50a, by tightening the nut 29, the long blade 25
It is now possible to apply tension to the Note that in this embodiment, a washer 43 is interposed on the threaded portion 31, but this washer 43 may be made of an elastic member such as a spring washer in order to make tensioning and fixing more effective. Furthermore, the tension member 27 fitted in the recess 44 is slidably fitted loosely within the recess 44 by crimping the plate 26a or the like on the upper part, but the plate 26a may be integrated with the tip 50a. It is also possible to arbitrarily replace the entire tensioning mechanism with another tensioning mechanism.
With this mechanism, the long blade 25 is stretched and fixed in a state where it can be replaced as appropriate, so it can be used appropriately depending on the hardness, surface, and cross-sectional structure of the fish, such as using a thick split blade for frozen fish and a sharp thin blade for fresh fish. In particular, when a thin blade is used, the tensioning and fixing mechanism prevents the thin blade from deflecting, making the thin blade even more effective in cutting. In addition, a shaft hole 41 is provided in the rear central part of the long blade mount 24, and one end of an arm 42 is rotatably attached thereto.The other end of the arm 42 is placed on the base 21 and extends through the base 21. It is connected via a cam 39 to the rotating shaft of a motor 37 with a drive section exposed at the bottom thereof, and is configured to convert the rotational motion of the motor 37 into horizontal reciprocating motion and transmit it to the long blade mount 24. . On the other hand, the inclined table C1'' is mainly constructed by connecting one end of a pair of side rods 33a and 33b, which are arranged parallel to the direction of fish movement with a gap of the above-mentioned pedestal width, by a horizontal member 34, and the other end is connected with a horizontal member 34. Relay rods 40a, 4 connected to the angle adjustment mechanism C2 of the inclined table C1''
0b is extended. Further, the inclined table C1'' and the movable cut-off portion C1' are attached to the side rods 32a and 32b arranged below both sides of the pedestal 21.
The cylinders 3 are connected to each other by slidably inserting the cylinders 3a and 33b, and are fixed to the horizontal member 34.
By connecting the tip of the piston 35 of No. 6 and the pedestal 21 and expanding and contracting the piston 35, the movable cutting section C
1' is guided by side rods 33a and 33b to enable reciprocating movement in the lengthwise direction of the fish body. The inclination angle of the tilting table C1'' is adjusted as follows. A support shaft 30 serving as a rotating shaft is horizontally fixed to the relay rods 40a and 40b, and the support shaft 30 is attached to the side casings 12a and 12b. Gas cylinder-shaped balancers 60a and 60b are attached to the tips of the relay rods 40a and 40b, which are supported rotatably through the support shaft 30 and are spaced a certain distance from the support shaft 30, respectively, so that the piston can be stopped at any position. As a result, the cutting device C can rotate around the support shaft 30 with the side of the horizontal member 34 in a free end state, and can be brought into a balanced state at an arbitrary inclination angle by the balancers 60a and 60b arranged at the other end. Also, a gear 73 is attached to the support shaft 30 across the side casing 12a.
is arranged, and a large-diameter gear 72 meshing with the gear 73 is used to transmit rotational force from a motor 71 provided at an appropriate position on the lower table via a belt 70.
By controlling the rotation of the motor 71, the inclination angle of the cutting device C can be adjusted. In this way, in this embodiment, the reciprocating movement of the long blade 25 and the adjustment of the cutting angle are realized.Although not shown in the drawings, by incorporating a mechanism for detecting the inclination angle at an appropriate position in the cutting device C, the conveying device A. It is possible to sequentially change the cutting angle of the fish body E in conjunction with the fish holding device B, and furthermore, the manipulator device D described later, which is optionally adopted, and it is possible to automate the creation of a wide variety of fillets. Furthermore, although not shown in the drawings, it is possible to change the configuration of the conveying device A and the fish holding device B to tilt the fish body E in the longitudinal direction and retain the fish body E, and to cut the fish body E in this state.

The manaita device D is optionally employed for transporting fish on the transport device A by placing fish thereon. For example, in the illustrated embodiment, synthetic resin,
For example, it is a vertically long, approximately rectangular flat plate in plan view made of a material such as polyethylene that is water resistant, corrosion resistant, and has an appropriate hardness to accept a partial cut of a long blade. A locking wall 8 having a width that allows fitting and sliding, and at the front of the upper short side in the direction of movement, prevents displacement in the length direction of the fish body during cutting.
2 are provided. In addition, in this embodiment, a small cylindrical iron material 83 is buried in the front side wall and works in conjunction with a magnetic proximity sensor 84 attached to the conveyance device A, transmitting its position information to the control section and controlling the coordinated operation of each device. It is possible. Although not shown, it is also possible to integrate the manaita device D with the conveyance device A, so that the conveyance path of the conveyance device A can be formed in an endless manner with simplified manaita, or the entire conveyance path can be formed in place of the manaita device. It is also possible to optionally replace the belt with a thick rubber belt or the like that can withstand partial cuts by a long blade for a certain period of time.

Next, the operation mode of the above-mentioned fish fillet manufacturing apparatus, which is a specific embodiment of the present invention, will be described. In the initial state, the manaita apparatus D is stopped at the entrance of the conveying apparatus with the locking wall 82 at the front in the direction of movement, and is manually operated. Or, by using a fish feeding device that is arbitrarily placed in the front stage,
A series of processes of this device starts when a fish E is placed on the manipulator device D in a lying position with the head in contact with the locking wall. When a fish is placed on the manaitor device D, the chain conveyor A1 is fixed in a certain direction by transmitting driving force from a motor installed on the lower stage, for example, via a belt A4, manually or by an automatic detection mechanism (not shown). It rotates at high speed and transports the fish body forward with the manaita device D placed thereon. In this embodiment, an iron piece 83 or the like is buried in the side of the manaita device, and the position of the fish is determined by a magnetic proximity sensor 84 placed at an appropriate position on the side wall of the transport device. Since it is managed, the subsequent operation timing of each device can be specified.

Information indicating that the fish body E has been transferred to a predetermined position is transmitted to the drive source of the fish holding device B, and the front and rear holding parts 10 and 11 are set so that the open ends are at the uppermost position, and then the holding parts are The fish body E is transferred to the space below the parts 10 and 11, and for example, in the illustrated embodiment, the movement during this time is as follows.

The information is output to the cylinders 7a, 7b fixed to the side casing 12b, for example, via a control unit disposed inside or outside, and controls the air supply and exhaust in the cylinders 7a, 7b to control the pistons 6a, 6a, 7b. 6b is shortened and raised, and while sliding the tip engaging portions 9a, 9b within the slide grooves 8a, 8b, applying rotational force in opposite directions to the support rods 4a, 4b fixed to the starting ends of the arms 5a, 5b, respectively. , lift the free ends of the holding parts 10 and 11,
The separation pieces 1 and 2 are aligned in the same plane and raised to the uppermost position, and then stopped after a space is provided at the bottom to serve as a passage for transferring the fish body. At this time, the inclination angle of the cutting device C is set in the initial state, but this angle can be set manually or automatically, and is controlled by the control unit above as well as the automatic setting of the inclination angle when cutting the fish body. It is also possible.
On the other hand, the manaitor device D, which has been transferred to a predetermined position below the fish holding device B by the chain conveyor A1, stops accurately at the predetermined position, and then the cylinders 7a and 7b
The pistons 6a and 6b are extended and lowered by controlling the air supply and exhaust, and the front and rear holding parts 10 and 11 are rotated using the support rods 4a and 4b as spindles so that their free ends descend, creating a gap that the long blade 25 can cut into. The fish body E is pressed appropriately, and the respective separation pieces 1 and 2 are individually moved up and down in response to the shape of the fish body at the bottom, and are pressed and held so as to wrap around them. At this time, the lower surface of each open end has approximately hemispherical small protrusions 3a and 3b that bite into the skin and engage with the fish body without damaging the surface layer of the fish body.
, the fish body E is stably held without swinging even during the reciprocating movement of the long blade 25. In addition, since each of the separation pieces 1 and 2 is made of a flexible material with elasticity, they move up and down independently, applying appropriate and even pressure to the surface layer of the fish body, and fitting and holding the fish body shape. Therefore, it does not damage the surface layer of the fish body and can be applied to various shapes and sizes. In particular, the separating piece 1 of the front holding part 10 is bent upward at the center to increase the area of contact with the fish body E, so that the fish body E does not follow vibrations when cutting the fish body.

Simultaneously with the lowering of the fish holding device B, a drive command is also transmitted to the cutting device C, and the motor 37 rotates in a fixed direction.
This is converted by the arm 42 into horizontal reciprocating motion to the left and right with respect to the direction of movement of the fish body, and is transmitted to the long blade mount 24. The long blade mount 24 and the pedestal 21 have dovetail grooves 6.
1, so that the long blade 25 starts horizontal reciprocating motion and controls the supply and exhaust of the cylinder 36 fixedly arranged on the horizontal member 34 to extend the piston 35. , the rod guides 32a, 32 on the side rods 33a, 33b.
The pedestal 21 is continuously advanced through the angle b, and cuts into the fish body E while vibrating in the width direction at the initial inclination angle. At this time, when the object to be cut is a raw fish, the fish body E is soft and the long blade 25 comes into pressure contact with the cut surface, so the fish body E and the long blade 25 are frictionally engaged, and the fish body position is pulled by the long blade 25. However, since the long blade 25 is reciprocating horizontally, the fish E will be pulled even in the subsequent movement in the opposite direction, so the fish E will not shift in only one direction. It will be located in the center on average. The long blade 25 performs horizontal reciprocating motion multiple times to create one fillet, but the specific number of reciprocating motions is determined depending on the type and size of the fish and the degree of hardness of the fish meat. Set. In addition, this cutting device C
Since the fish body E is cut by the horizontal reciprocating motion of the long blade 25, it is possible to completely separate the fish body E without leaving any part uncut, unlike when cutting with a round blade. If the long blade 25 cuts the fish body E and comes into contact with the lower manaita device D,
The piston 35 is shortened and the pedestal 21 is attached to the side rod 3.
The pistons 7a, 7b are removed from the fish body E by sliding backward on the pistons 7a, 7b.
is shortened to release the front and rear holding parts 10 and 11 above the fish body E. At the same time, the chain conveyor is rotated by a certain amount, and the manaitor device D is advanced by a pitch corresponding to the cutting interval of the fish body E, and the next fish body is cut. The fish holding device B is moved to a predetermined position and stopped, and the fish holding device B is lowered to hold the fish in the same manner as described above. Meanwhile, the cutting device C automatically changes and sets the inclination angle during this time, and the operation mode is as follows.

When the motor 71 is rotated by a certain amount based on an appropriate command, the rotational force is transmitted to the gear 73 via the chain belt 70 and the gear 72 to rotate the support shaft 30, but the horizontal member 34 side of the inclined table C1'' is at the free end. Since it is rotatably supported by the device main body, the rotation of the support shaft 30 causes the free end side of the inclined table C1'' to rise or fall in accordance with the amount of rotation, and the set angle of the long blade 25 changes. That's what happened. Furthermore, since the cutting device C is always in a balanced state by the balancers 60a and 60b disposed at one end, the inclination angle of the cutting device C can be increased or decreased with a small amount of torque. The range of increase/decrease in the angle of inclination determines the appearance of the fillet to be created, and can be determined appropriately depending on the shape of the fish. By registering the method, it is possible to automatically produce fillets suitable for the shape of the fish body. After setting the angle, lower the front and rear holding parts 10 and 11 again, repeat the above process, change the angle each time, and cut the entire fish body using the above method to obtain good-looking fish fillets. It happens. The filleted fish body E is transferred to the exit of the conveying device A while being placed on the manaita device D, and is taken out of the device by appropriate means.

In this embodiment, the holding parts made up of the separation pieces 1 and 2 are arranged at the front and back, but it is also possible to use only one holding part and replace the other with another simple locking mechanism. Similarly to extending the length of the long blade 25, by increasing the number of separation pieces 1 and 2 to appropriately widen the width of the holding part, it is also possible to hold multiple fish bodies E arranged side by side. It is something. In addition, the above-mentioned conveyance device A, fish holding device B, cutting device C, manaita device D
For example, magnetic sensors, optical sensors, etc. are attached to appropriate locations in the equipment, and operational information is sent in real time to a control mechanism such as a computer placed externally or internally, and the operation of each device is managed using software. For example, the operation of each device can be made flexible and organic, and a wide variety of fish cutting processes can be performed with a single device.

According to the method for making fish fillets according to the present invention, since the fish body is cut by horizontal reciprocating motion of the long blade, the same device can be used to cut all kinds of fish bodies, such as frozen fish and raw fish, and the fish body position is maintained at a predetermined level on average. Due to its location, it is now possible to cut raw fish with high precision, which was previously considered difficult. At the same time, since there is no shift in the position of the fish body due to fish meat traction, the cutting is smooth and beautiful, and there is very little tissue destruction, so it is possible to improve the quality visually and tastefully, and the cutting inclination angle and cutting pitch can also be set appropriately. Therefore, it is possible to easily create a variety of fillets according to the type and shape of the fish, and it is possible to significantly increase the commercial value of the fish. In addition, since the long blade makes a horizontal reciprocating motion, even if the fish body is wide, it will not leave a part uncut like a conventional rotary blade. It is also possible to cut the tail fish bodies in parallel in the width direction of the fish body, which can be expected to significantly improve production efficiency.
