Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fish fillet manufacturing device, and more specifically, a fish fillet manufacturing device in which a cutting device can be rotated to appropriately set the cutting angle into the fish. By always maintaining the position where the cutting blade cuts into the surface layer of the fish body and the position where the holding device presses the fish body at a constant close position, it is possible to eliminate the escape of the fish when cutting the fish body, and to make it possible to cut the fish body with higher precision. The present invention relates to a fish fillet manufacturing device that can provide fillets with high commercial value.

[Conventional technology]

Traditionally, fish fillet manufacturing equipment uses a rotary round blade or a saw blade as a cutting device, and as a holding device, the sides and top of the fish body are clamped and fixed with a flat plate or a curved plate having a curved part that conforms to the shape of the fish body. It has been known. However, when cutting with this cutting device and holding device, the fish body is pulled by the cutting blade and shifts, making it difficult to cut with high precision.
The cut surface of the obtained fillet was also not smooth and had a poor appearance. In order to solve these problems, there is a fish fillet manufacturing apparatus filed by the same applicant as Utility Model Application No. 104221/1982. What is shown in Figure 5 is an outline of this device, in which A in the figure is a conveying device, B in the figure is a holding device, C in the figure is a cutting device, D in the figure is a manaita device, and E in the figure is a fish body. . The transport device A has the function of intermittently transporting the manait device D and the fish E placed thereon at arbitrary pitches, and the holding device B is placed before and after the cutting device C, respectively. As shown in FIG. 6, the structure is such that one end of a plurality of separation pieces a, which move up and down independently according to the shape of the fish body, is fixed by a support rod a'. Further, the cutting device C mainly consists of a side rod b arranged in parallel as shown in FIG. The moving cutting section d
is moved back and forth in the longitudinal direction on the side rod b by the cylinder f fixed to the horizontal member e located on the free end side of the side rod b, and the cylinder is expanded to the maximum extent. When this happens, the long blade g attached to the tip of the movable cutting part d is configured to come into contact with the upper surface of the manaitor device D. And this long blade g
is attached to the pedestal h of the movable cutting part d via a slidable engagement part i so that the side rod b can move back and forth in the longitudinal direction and at the same time can reciprocate in a direction perpendicular to said direction. There is. Further, at a position one step before the starting end side k of the relay rod j extended to the side rod b and approximately coincident with the upper surface side of the manaitor device D, there is a rotation support that allows the cutting device C to rotate. The shaft m is horizontally fixed with a drive means l associated with one end, and a balancer n is associated with the starting end side k for receiving the weight of the cutting device C in a buffer manner and smoothing the rotation of the cutting device C. ing.

The fish fillet manufacturing apparatus constructed in this way holds the fish E being transported by wrapping it in the holding device B disposed before and after the cutting device C, and also holds the fish E being carried at right angles to the transport direction of the fish E. This device cuts the fish E with a long blade g that moves forward while reciprocating in the direction.It eliminates deviation in the placement position of the fish E, enables highly accurate cutting, and also allows the cutting angle to be adjusted around the spindle m as the center of rotation. It is possible to create a wide variety of fillets by appropriately changing the .

[Problem that the invention seeks to solve]

In the above device, the fish body E is held under pressure so as to wrap around the cutting device C at the front and back, so the fish body E is stably held even with the reciprocating movement of the long blade g. There was a problem in that when the device C was tilted, the cutting position of the long blade g into the fish body E changed and the distance from the holding device B could not be kept constant.
To explain this in more detail, as shown in Figure 8A, with this device, the fish body E is completely cut and at the same time the long blade g comes into contact with the upper surface of the manaita device D. In order to avoid the load, it is preferable that the moving distance of the movable cutting part d is always constant, and the contact position r of the long blade g with the manaiter device D is always constant regardless of the inclination angle of the cutting device C. And in order to satisfy this condition, the cutting device C
The arrangement position of the rotational support shaft m is approximately aligned with the upper surface of the manaitor device D, as shown in FIG. 8B. However, conversely, at a position a certain distance upward from the upper surface of the manaita device D, the horizontal position of the long blade g shifts according to the inclination angle of the cutting device C. For example, the cutting position s into the surface layer of the fish body E is It means a shift in the horizontal direction according to the inclination angle. For example, the inclination angle of cutting device C is α1
The cutting position s is shifted by β between the case of and α2, but this naturally limits the horizontal arrangement position of the presser device B, and the presser device B is moved within the above deviation range in order to avoid collision with the long blade g. This means that it cannot be placed in This makes it impossible to press and hold the fish body E at close range with the long blade g, causing so-called play and making it unstable to hold the fish body E during cutting. This made it difficult to make the amputation. The previous application attempted to avoid this problem by arranging the presser device B before and after the cutting device C, but this method made the device complicated and did not allow for miniaturization of the device. There was also a problem with the timing of lowering the presser device B, and this was considered to be a problem that needed to be solved.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and achieves a much simpler device that presses and holds the fish body more stably than the above-mentioned holding device, and eliminates the shift of the fish body during cutting. The purpose of the present invention is to provide a fish fillet manufacturing device that can quickly produce large quantities of fish fillets with good appearance.This is achieved by moving the horizontal position of the holding device in accordance with the inclination of the cutting device. The main points are: a transport device for transporting fish, a manaita device for placing fish, a cutting device for cutting fish, and a device for holding fish. The cutting device has a long blade that cuts into the fish while reciprocating and moves forward until it comes into contact with the upper surface of the manaita device. The holding device is constructed by providing a rotating support shaft associated with a rotational drive means at an appropriate position that substantially coincides with the side position of the upper surface of the device; and a horizontal moving part that moves horizontally as the rotation angle changes; the holding part has a pressing plate that is elastically biased in the vertical direction and can be moved up and down individually, on a horizontal crossbar supported by a lifting mechanism. A large number of horizontal moving parts are arranged in parallel in the width direction of the fish; the horizontal moving part supports the presser part via the lifting mechanism and has a sliding part that can be slid back and forth in the length direction of the fish; At a proper position on the sliding part, the other end of an arm is pivoted, one end of which is pivoted in the vicinity of the rotational support shaft of the cutting device and at a position where the component force of the rotational operation of the cutting device can be transmitted to the sliding part. The device is rotatably mounted to constitute a fish fillet manufacturing device.

[Effect]

In such a fish fillet production device, the pressing plates that make up the holding device move up and down independently with appropriate pressing force according to the shape of the fish body, so the fish body can be wrapped around the shape without being damaged. In this way, the holding part receives component force from the rotating operation of the cutting device so that the horizontal position at which the pressing plate presses the fish body is always near the position where the cutting blade cuts into the fish body. Since the fish body is moved horizontally, the fish body is always stably pressed and held, and the fish body does not vibrate during cutting, making it possible to cut with high precision.

〔Example〕

Next, details of the present invention will be explained focusing on the presser device. What is shown in FIG. 1A and B is an embodiment showing a method of horizontally moving the presser device in accordance with the inclination angle of the cutting device, and C in the figure shows the cutting device,
D is the manaita device, E is the fish body, F1 is the holding part, F
Reference numeral 2 denotes a horizontal moving section, and the presser device F is composed of both F1 and F2. The horizontal moving part F2 is positioned as a device that mediates the cutting device C and the holding part F1, and is arranged in a symmetrical shape on the outside of the casing 1 on both sides, but only the structure of one of them will be described here. A slide base 5 having a recess 4 that engages with the protrusion 2 is abutted and engaged with a base 3 having a protrusion 2 fixed to the side casing 1 in a horizontally slidable state, and A sliding portion 8 is formed by fixing to the outer surface of the slide table 5 a movable plate 7 on which a lifting cylinder 6 of a presser portion F1, which will be described later, is fixed to one side. A protruding rod 9 is provided on the other side of the movable plate 7 at a certain distance from the mounting position of the lifting cylinder 6, and an arm 10 for transmitting driving force is rotatably provided at the tip of the protruding rod 9. Attached to the shaft,
Further, the other end of the arm 10 is rotatably attached to a shaft support 11 on the relay rod j of the cutting device C and set at a position above at least the rotational support shaft m of the cutting device C. . Further, the structure of the holding portion F1 horizontally moved by the horizontal moving portion F2 constructed in this manner is shown in FIGS. 2 and 3, for example. The presser part F1 has a plurality of through holes 15 provided at regular intervals in a horizontal rod 14 which is supported on both sides of the piston 12 in the vertical direction via an extending rod 13, and a plurality of through holes 15 are provided in the through holes 15. A press rod 17 having a head 16 with a larger diameter than the inner diameter of the through hole 15 is passed through it via a washer 18, and the lower end of the press rod 17 is extended in the direction of transporting the fish body and has grooves on both sides in the length direction. A pressing plate 19 having a U-shaped cross section and having a saw-shaped bent portion 20 is fixed thereto, and a spring 21 is interposed between the pressing plate 19 and the horizontal rod 14 to moderately push the pressing plate 19 downward. It has a configuration in which it is pressed down. The press rod 17 and the press plate 19 are attached in a loosely fitted state as shown in FIG. It is also possible to have a swingable configuration. Further, in the front of the pressing plate 19 in the direction of transporting the fish body, there is a bent part 22 which is bent slightly upward.
is provided, and when the long blade g and the pressing plate 19 come closest to each other, the long blade g touches the bent portion 2 as shown in FIG.
It is set so that it slides under 2.

An outline of the operating mode of the presser device F constructed in this manner is as follows. FIG. 4 is a diagram showing the movement of the horizontal moving part F2, where D is the manaitor device, the part indicated as o is the rotational support shaft m of the cutting device C, and u1, u2, and u3 are the support shafts of the relay rod j. m
Corresponds to the shaft support 11 at the upper position, θ1, θ2, θ
3 indicates the inclination angle of the cutting device C. The portions indicated as x1, x2, and x3 are the movable plate 7.
z1, z2, and z3 correspond to the set positions of the protruding rod 9 of the movable plate 7. For example, when the angle between the cutting device C and the manipulator device D is θ1, the shaft support is located at u1 and the arm position is x1. Similarly, when the angle is θ2, the shaft support is located at u2 and the arm position is x2, and during this time the position of the protruding rod 9 at the other end of the arm shifts from z1 to z2, taking a deviation of Δz. Become. That is, as the inclination angle of the cutting device C increases, the shaft support 11 rotates counterclockwise in the figure around the support shaft m, and as a result, the arm 10 pivotally attached to the shaft support 11 moves to the left side in the figure. You will be under pressure. And this arm 10
The movement is caused by the shaft attachment part 23 with the protruding rod 9 at the other end of the arm.
is pushed to the left in the figure, and the movable plate 7 to which the sliding part 8 is associated is guided by the engagement mechanism of the sliding part 8 and moves horizontally to the left in the length direction of the side casing 1. . As the movable plate 7 moves horizontally, the presser foot F1 supported via the lifting cylinder 6 also moves horizontally in the same direction, so the distance between the long blade g and the pressing plate 19 is
Despite the rotation, it always remains almost constant. The presser foot F1, which moves horizontally as the cutting device C rotates, takes the following operating mode. When the cutting device C is set at a desired angle and the holding part F1 is moved horizontally by the method described above, the fish E placed on the manaita device D is moved to the holding part by the conveying device A. F
1 is transferred to the lower part. The position of this fish E is managed by a position management mechanism (not shown), etc., and after being transported to a predetermined position, it stops, and the position management mechanism transmits the position information to a control mechanism (not shown). Next, the lifting cylinder 6, which has received this information, shortens the piston 12 by a predetermined distance, and lowers the horizontal rod 14, which is horizontally suspended from the piston 12 via the extending rod 13, by a predetermined distance. As the crosspiece 14 descends, a large number of press rods 17 arranged in parallel on the crosspiece 14 also descend, but the press rods 17 are configured to be able to move up and down with the press plate 19 at the lower end being biased vertically downward by a spring. Therefore, each pressing rod 17 is
As shown in Figure B, the fish body shape is individually and independently transformed, and the fish body is held together with an appropriate pressing force.
This pressing force is set to a level that does not damage the surface layer of the fish body, and varies depending on the number of pressing rods 17, but in general, the larger the number of pressing rods 17, the more it is possible to hold the pressure in accordance with the shape of the fish body. The size and shape of the pressing plate 19 are set in consideration of the above. Further, in this embodiment, since a saw-shaped bent portion 20 is provided on the side of the pressing plate 19, the bent portion 20 is
0 partially bites into the surface layer of the fish body, causing the fish body E.
The holding of fish becomes more effective, and both fresh fish with elastic surfaces and frozen fish with rigid surfaces can be held securely with the same device. Furthermore, a bent portion 22 that is bent slightly upward is provided at the front of the pressing plate 19 in the direction of transporting the fish body, so that the long blade g can be tilted toward the bottom of the pressing plate 19 even when cutting a fish body that is thin and lacks rigidity. By entering the fish body E in this state, the long blade g holds the fish body E at a close distance, and even thin fish bodies can be reliably cut.

〔Effect of the invention〕

In the fish fillet manufacturing apparatus constructed as described above, the presser device corresponds to the inclination angle of the cutting device.
Since it moves in the horizontal direction, it is possible to always press and hold the fish body near the position where the cutting blade cuts into the fish body, which eliminates the so-called play between the cutting blade and the holding device, and the cutting operation of the cutting blade is controlled. This device can effectively suppress the accompanying vibrations of the fish body and stably hold the fish body, making it possible to cut the fish body as if a chef were cutting the fish with a knife while holding the fish in the palm of his hand. It is something. In addition, since the holding part of this holding device is composed of a plurality of pressing plates that move up and down independently, the fish body is stably held in place with an appropriate pressing force, and there is no damage to its external shape. This not only makes it possible to cut with high precision, but also to create fillets with good appearance, and together with the versatile use of cutting angles, it is possible to increase the commercial value of the fillets. In addition, the driving force for horizontal movement of this holding device is obtained from the rotational movement of the cutting device, so there is no need for a special drive source, and the holding device itself is placed in two, front and back of the cutting device, as in the past. There is no need to do this, and the fish body can be held stably by simply placing one in front of the cutting device, so the fish fillet manufacturing device can be made smaller and the manufacturing cost can also be reduced.
