FIG. 1 is a front view showing a frozen fish cutting apparatus 1 according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. The frozen fish cutting device 1 includes a base 5, a processing table 6, a cutting unit 10, and a feeding device 7. The processing table 6 is provided on the base 5 and mounts and processes the frozen fish 9 to be cut. The front end of the processing table 6 is a cutting position P, and a notch 1
2 are formed. The cutting means 10 includes a support rod 10 fixed to the base 5 and extending vertically, a pair of pulleys 2 and 3 provided at both ends of the support rod 10,
An endless cutting wire 4 that is stretched and wound over the gap, and a motor 8 that drives one pulley 3 to rotate. Each of the pulleys 2 and 3 has a horizontal rotation axis, and is arranged at intervals vertically in the vertical direction. One stretched portion of the cutting wire 4 wound around the pulleys 2 and 3 is stretched vertically between the notches 12 at the cutting position P in a tensioned state. The pulley 3 disposed below is driven by a motor 8 provided on the base 5 to rotate the pulley 3 so that the cutting wire 4 is directed downward at the cutting position, as indicated by an arrow A in FIG. The cutting wire 4 is driven to circulate.

On the processing table 6, a delivery device 7 for the frozen fish 9 is provided. The feeding device 7 holds the frozen fish 9 to be cut upright and sandwiches the frozen fish 9 from both sides to send the frozen fish 9 toward the cutting position of the cutting wire 4.

The frozen fish 9 is a large fish such as a skipjack or a tuna.
It was frozen rapidly. The delivery device 7 is driven by the motor 8 described above, and the frozen fish 9 is gradually moved forward (toward the paper surface in FIG. 1 and downward in FIG. 2) toward the cutting position P by the delivery device 7. By being sent out, it is cut by the cutting wire 4 in the craniocaudal direction along the medial bone.

FIG. 3 is an enlarged front view of the cutting wire 4.
FIG. 4 is a sectional view of the cutting wire 4. The cutting wire 4 is
It is composed of a flexible steel wire rope 15 and a cutting layer 16 that covers the wire rope 15 and forms a cutting blade. The wire rope 15 has an outer diameter φ1
= 1.5 to 2.5 mm, and the cutting layer 16 is fixed to the outer surface of the wire rope 15 by electroplating.

The cutting layer 16 has a particle diameter D1 = 50-100 μm.
The cutting layer has a thickness T of about 200 to 250 μm.
As the binder, for example, a nickel-based metal bond made of a silver-nickel-cobalt alloy is used. As the powder 17, fine diamond particles are used. When these are coated on the wire rope 15, diamond fine particles are sufficiently mixed in a nickel plating bath, and the wire rope 15 is coated on the wire rope 15 by eutectoid plating under strong stirring.

Since the wire rope 15 is formed by twisting a plurality of strands, the surface becomes uneven, so that the coating layer 16 having the powder 17 is easily fixed. The cutting wire 4 is roughened by the coating layer 16 containing such a hard granular material, and the frozen fish 9 can be cut by being driven in the stretching direction.

The cutting wire 4 can be cut in any direction in the radial direction with respect to the cutting wire 15 because the hard granular material 17 is fixed over the entire outer surface. Therefore, even if the frozen fish 9 to be cut is twisted and frozen, it is possible to cut the frozen fish 9 accurately along the bent frozen fish 9.

The powder 17 is made of diamond.
When diamond is crushed, a sharp tip appears, has a spontaneous cutting action that maintains the cutting action, and has excellent wear resistance. The cutting wire 4 is connected to the wire rope 15 by the hard powder 1
Since the wire 7 is formed so as to be covered, it is difficult to bend as compared with a normal wire rope. Therefore, the pulleys 2 and 3 around which the cutting wire 4 is stretched need to have a diameter at least 250 times the outer diameter of the wire rope 15. For example, when the wire rope 15 has a diameter φ1 = 2 mm, the pulleys 2 and 3 The diameter is 50 cm or more.

The powder 17 is not limited to diamond, but may be ceramic or a powder made of tungalloy (trade name) which is a cemented carbide obtained by sintering tungsten carbide.

Since the cutting wire has the cutting blade on the outer periphery as described above, it can be cut from any direction of 360 °. Therefore, even if the direction in which the frozen fish 9 is sent out by the sending device 7 changes greatly,
The frozen fish 9 can be cut accurately along the middle bone.

The front roller 23 has a radius smaller than the radius of curvature of the curved portion of the frozen fish to be cut so that the curved frozen fish can be accurately guided. When cutting the frozen fish 9 that is curved as shown in FIG.
The belt means 21 and 22 are arranged so that their rear portions are opened in a C-shape so that even if the tail portion 38 is greatly swung in this manner, the belt means 21 does not interfere with the swing.

Further, in such a feeding device 7, since the pair of front rollers 23 for sandwiching the frozen fish 9 are urged by the spring members 29 in directions approaching each other,
Irrespective of the size and the degree of bending of the frozen fish 9 to be cut, it is possible to securely pinch and send out. Further, the delivery device 7 may be configured such that the frozen fish 9 is delivered only by the front roller 23 without providing the belt 30.

By shifting the cutting position P,
The frozen fish 9 can be cut in the head-to-tail direction at a position shifted from the middle bone. As described above, a configuration may be adopted in which an adjustment unit that can adjust the cutting position P is provided. In addition,
Since the cutting wire 4 has a cutting blade on the outer periphery, it can cut into the frozen fish from any angle.

As shown by the imaginary line in FIG. 1, a part of the cut wire 4 after cutting is immersed in water in a water tank 40,
Thus, clogging of the cutting blade of the cutting wire 4 may be eliminated. At this time, high-frequency vibration such as ultrasonic waves may be applied to the water in the water tank 40 to efficiently eliminate clogging.

Also, instead of cutting the frozen fish 9 into two,
For example, when cutting into four pieces, the cutting means 45 is used as shown in FIG. The cutting means 45 has pulleys 46 and 47 having three grooves.
Then, the cutting wires 4 are respectively stretched. Such a cutting means 45 is arranged such that the horizontal rotation axis of each pulley 46, 47 is perpendicular to the center line L1 of the feeding device 7, and the cutting area of the three cutting wires 4 is It is arranged to be in front. By such a cutting means 45, the frozen fish 9 sent from the sending device 7 is cut into four pieces along the middle bone. Each pulley 4
By stretching two cutting wires 4 on 6, 47, the frozen fish 9 can be reduced to three pieces.
