Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention uses dried bonito flakes, mackerel flakes, or artificial fish flakes made by drying and solidifying livestock meat, fish meat, etc. to form bonito flakes. This invention relates to a method for cutting fish flakes that can cut flakes of a constant thickness.

(Prior art) The rotary blades used in the conventional cutting method for fish joints are roughly divided into those using a planer-like plate blade and those using a blade roller with a helical blade formed on the outer periphery of the roller. There was something there.

The former cutting method using a rotating blade includes the following methods.

A method of cutting by pressing against the

As shown in FIG. 4, a plate-shaped blade a is attached to the mortar-shaped surface h of a rotary plate d, and the bonito flakes are pressed against the plate-shaped blade a to cut the dried bonito flakes.

As for the latter cutting method using a rotary blade, as shown in Fig. 5, two blade rollers j having helical blades i formed on the outer periphery of the rollers are arranged in parallel, and while they are rotated, the two blade rollers j are There was a method in which the fish c was pressed by a spring k to cut it.

(Problems to be Solved by the Invention) However, among the various methods described above, the former four methods using the plate-shaped blade a all have the following common drawbacks.

(1) During cutting, the ichthyophores c are bitten into the plate-shaped blade a, and the impact at that time may cause the ichthyophores to chip off, resulting in chunks of ichthyophores being mixed into the scraped pieces.
This becomes a cause of irregular shapes, and when put in the mouth, it hits the teeth and feels like a foreign body, impairing the taste.

(2) It is easy for shavings and powder to become clogged between the rotary plate d and the plate-shaped blade a installed by being inserted into the blade insertion hole, and if the blockage occurs, the protrusion dimension of the plate-shaped blade changes, so it is difficult to maintain a constant thickness. This is not desirable in terms of food hygiene, as it cannot be scraped quickly, and during the rainy season or in a hot and humid working environment, this can cause the growth of bacteria.

(3) With a plate-shaped blade, the cutting resistance is large, so the blade is subject to severe wear. Therefore, the protruding dimension of the blade must be adjusted frequently or the blade must be changed, and the cutting operation must be stopped each time. As a result, work efficiency and productivity deteriorate.

(4) Among the cutting methods shown in Figures 1 to 4, in the one shown in Figure 2, the dried bonito flakes c are pressed by a spring e, so the bonito flakes are thinner before and after being cut. In the case of drying, the pressing force of the spring e changes, causing variations in the pressing force, and as a result, the thickness of the cut joints to be cut tends to be non-uniform.

(5) Since the fish pieces c are pressed by the spring e, the fish pieces c are constantly pressed against the rotating plate d and heated, which may cause the fish pieces to oxidize, lose flavor, or become discolored. It gets worse.

(6) In the cutting method shown in Figure 3, the bonito flakes are not pressed by a spring, but are fed a fixed amount by a feed screw g, so the above-mentioned drawbacks of the cutting method shown in Figure 2 are alleviated to some extent; Since the cutting tool used for cutting is a plate-shaped blade, if the feed amount of the fish c is reduced so that it only contacts the plate-shaped blade a without contacting the rotating plate d, the fish It becomes unstable and cannot be cut. Therefore, in order to cut the fish c, it is necessary to press it not only against the plate-shaped blade a but also against the rotary plate d as shown in FIG. For this reason, it is still unavoidable that the fish and fish may become overcooked or lose their luster.

(7) When the fish joint c is pressed against the rotary plate d, the thickness of the shaved joint to be cut is determined by the protruding dimension of the plate-shaped blade a (the thickness will be the same as the protruding dimension, and it will not be thicker or thinner than that). Even if you adjust the rotational speed of the rotary plate d or the feed rate of the fish flakes c, the thickness of the shaved flakes cannot be adjusted.

(8) In order to adjust the thickness of the shavings, it is necessary to stop the rotation of the rotary plate d and adjust the protruding dimension of the plate-like blade a, which is troublesome. Moreover, in this case, the greater the number of plate-shaped blades a attached to the rotary plate d, and the longer the length of the plate-shaped blades a, the longer the adjustment takes, which significantly reduces work efficiency and productivity. descend.

(9) If the plate-shaped blade a is long, it is difficult to make it protrude uniformly over its entire length, and if there are many blades, only one blade may protrude excessively.
In that case, the fish c is strongly pressed only by that blade, and the other blades are not sufficiently pressed, resulting in a decrease in cutting speed. Moreover, unreasonable force is inevitably applied to the extremely protruding blade, which distorts the rotary plate d, resulting in uneven thickness and shape of the cut joints.

(10) It takes a long period of skill to be able to uniformly adjust all of the many plate-shaped blades a, and even for an experienced person, it takes approximately 3. It takes about 5 minutes. Furthermore, even experts make adjustments based on their intuition, so there is considerable variation depending on the time of adjustment and the sharpening machine used. What's more, if the person making the adjustment changes, there will be variations even with the same shaving machine, and as a result, the thickness of the shavings will also vary.

(11) In the case of Fig. 4, the rotating body d is mortar-shaped, so the stability of the ichthyophores is improved compared to the case of Fig. 2, but the blade used is a plate-shaped blade a. Therefore, the drawbacks caused by its use still remain. Moreover, since the rotary plate d is mortar-shaped, the center of the tip of the ichnos is inevitably guided to the mortar-shaped center (the part without the plate-like blade), and the center of the ichnos There is also the disadvantage that some parts remain uncut.

(12) Among the conventional cutting methods, in the cutting method using the blade roller j as shown in Fig. 5, the fish pieces c are pressed against the blade roller j by a spring k, so the fish pieces are pressed against the blade roller j. Therefore, whether or not it is being cut, it is constantly pressed against the blade roller, and more pressing force than necessary is applied to the helical blade i. Therefore, the cutting resistance increases, the blade becomes more likely to wear out, and the quality deteriorates, such as heating, loss of flavor, and poor color luster.

(13) When the two blade rollers are both rotated inward as shown in Figure 5 B, when they are both rotated inward as shown in Figure 5 C, one is rotated outward and the other is rotated inward as shown in Figure 5 D. In any case when rotating, if the pressing force of spring k is weak, fish c.
is pushed back by the rotational force of the two blade rollers i and becomes difficult to cut, so the pressing force of the spring k must be at least equal to or slightly stronger than the rotational force of the two blade rollers j.
However, if the pressure is too strong, excessive force will be applied to the blade roller j, making it difficult for the blade roller j to rotate. If you dare to rotate it, the fish joint c may chip or crack, and in some cases the blade roller j may
The helical blade i may even chip.

(14) In the case of Fig. 5 B, since the rotation directions of the double-edged rollers j are opposite to each other, the ichnoclage c is easily cracked, chipped, or torn, and its shape, thickness, etc. are almost constant. It is difficult to obtain shaved bonito flakes. Furthermore, it is impossible to cut the material as thin as several microns.

(15) When two blade rollers j are used, it is not possible to make them contact each other, so it is necessary to separate them. If they are separated, the fish joints will not be cut by that much, and they will enter between the blade rollers. The blade roller may stop rotating.

(16) In the case of Fig. 5 C, the two blade rollers j rotate inward, so if the double-edged rollers j are placed close together, the cut knots will get stuck between the blade rollers. This prevents the shavings from being discharged to the outside. In order to solve this problem, the double-edged roller j must be spaced a little apart, and if this is done, the fish pieces c will remain uncut by that distance, and the remaining pieces will be drawn between the double-edged rollers j. The blade roller j
The rotation of the roller stops, as if it were a double-edged roller.
The situation is like that of a crusher that crushes the fish flakes c between them, causing the fish flakes c to chip, crack, or crumble, making it impossible to obtain shaved flakes of a very constant thickness.

(17) In the case of Fig. 5 D, one blade roller j rotates inward and the other blade roller j rotates outward, so that the cut surface of fish c is slightly left L from the center 0. A cutting force directed downward to the right is applied by the left blade roller, but a cutting force directed upward to the right is applied by the right blade roller to a portion R slightly to the right of the center portion 0. For this reason, cutting forces in completely opposite directions are applied to the central part of the fish joints c, causing chipping or cracking of the fish joints c, making it difficult to obtain shaved joints of a constant shape.
Also in this case, if the two blade rollers j are not separated, the shavings cut by the left blade roller j will not be discharged, so the double-edged roller j must be kept a certain distance apart. The rotation of the blade roller j may stop due to the unsharpened pieces of fish getting stuck in between.

(Object of the invention) The object of the present invention is to avoid the various drawbacks mentioned above,
It is possible to cut kerifobushi with a constant thickness, and by adjusting the rotational speed of the rotary blade and/or the feed rate of the fish to be cut, the thickness of the cut bonito flakes can be adjusted. An object of the present invention is to provide a method for cutting fish joints that allows adjustment of the amount of fish.

(Means for Solving the Problems) As shown in FIGS. 6 to 8, the method for cutting fish joints of the present invention is as follows: Rotate only one rotary blade 4 having a cutting edge 3 formed on the outer circumferential surface 2 in a fixed direction, and clamp the rear end of the fish segment A with the clamping jig 11. The jig 11 is transferred along the guides 9 and 10 by the transfer body 5, and the outer circumferential surface of the fish segment A is brought into contact with the cutting blade 3 of the rotary cutter 4. At the time of cutting, the transfer body 5 is transferred to the rotary cutter 4 side at a speed corresponding to the amount of rotation of the rotary cutter 4, and the same fish A is continuously transferred in the same direction. The outer periphery of the cutter A is brought into continuous contact with the rotary cutter 4 while the shake of the tip side of the cutter A is prevented by the shake stopper 6.

(Function) To cut the fish A by the fish cutting method of the present invention, turn the knob 20 in FIG.
Open it and insert the ichthyophore A between the receiving recesses 21 and 22 in Fig. 9.
, and then turn the knob 20 in the opposite direction to close the presser body 13 and clamp the fish A.

Next, turn the knob 29 in FIG. 9 to tilt the movable piece 24 toward the Y′ side in the same figure, and align the screw groove 30 in FIG.
The meshing of the feed shaft 8 with the feed screw 7 is released. In this state, the clamping jig 11 shown in FIGS. 7 to 9 is manually transferred to the rotary cutter 4 side along the two guides 9 and 10, and the tip of the fish segment A is moved to the side shown in FIGS. 7 and 8. It is inserted into the steady rest hole 31 of the steady rest 6 shown in the figure and brought into contact with the rotary cutter 4.

Thereafter, the knob 29 in FIG. 9 is turned in the opposite direction to the previous direction to raise the movable piece 24 in the Y direction in the figure and engage the thread groove 30 with the feed screw 7. If the rotary cutter 4 shown in FIGS. 7 and 8 is rotated in this state, the fish pieces A that come into contact with the cutting blade 3 on the outer peripheral surface of the rotary cutter 4 are cut. As the cutting progresses and the outer shape of the fish A becomes smaller, the rotary knife 4 and/or the fish A become smaller (in the case of Fig. 8, the rotary knife 4 is moved to the fish A side). , so that the ichthyophore A can be cut after that.

(Example) The one shown in FIGS. 6 to 10 is an example of a shaving machine used in the method for cutting fish and fish of the present invention.

This is done by rotating a rotary cutter 4 manually or automatically by a motor, and using a cutting edge 3 formed on its outer circumferential surface 2, the outer circumferential surface of a round rod-shaped fish A with a diameter of 2 to 3 cm is brought into contact with it. At the same time as cutting B, the transfer body 5 is moved by the rotation of the rotary knife 4, so that the fish pieces A are continuously transferred to the rotary knife 4 side.

The rotary cutter 4 has a cutting edge 3 formed on the outer circumferential surface 2 of a rod-shaped, cylindrical or disc-shaped base material 1 in which no blade protrusion hole is formed. Figures 6 to 8
In the case of the figure, the spiral cutting edge 3 is the base material 1.
Two pieces are formed integrally from the outer periphery to the tip.

The transfer body 5 has a feed shaft 8 having a feed screw 7 formed on its outer periphery, and when the feed shaft 8 rotates, it moves toward the rotary cutter 4 side along round bar-shaped guides 9 and 10 at a speed corresponding to the amount of rotation. It consists of a clamping jig 11 that is continuously transferred.

As shown in FIGS. 9 and 10, the clamping jig 11 includes a jig main body 12 through which the guides 9, 10 and the feed shaft 8 pass, and a presser foot that overlaps with the main body 12 and presses the fish A. As shown in FIG. 9, the presser body 13 has an upper end 14 attached to the main body 12 with a bolt 16 via a spring 15, and a lower end 1.
7 is attached to the main body 12 with a bolt 19 via a spring 18, and when the knob 20 of the bolt 19 is turned, the presser body 13 moves in the direction indicated by the arrow X-- in FIG.
It is designed to open and close in the X′ direction. By opening and closing, the fish A is inserted between the triangular receiving recesses 21 and 22 that are formed to face the main body 12 and the presser body 13, and the fish A is made to be clamped and released. It is set as.

In addition, the clamping jig 11 has a movable piece 24 disposed in a storage portion 23 shown in FIG. is rotatable in the direction of arrow Y-Y'.

Furthermore, a screw hole 2 opened at the upper end of the movable piece 24
6, the threaded part 28 of the bolt 27 inserted from the presser body 13 side is screwed in, and by rotating the knob 29 of this bolt 27, the movable piece 24 is tilted in the Y-Y' direction with the pin 25 as a fulcrum. Try to stand up.
When the movable piece 24 stands up in the Y direction, the thread groove 30 formed thereon and the feed screw 7 on the outer periphery of the feed shaft 8 mesh with each other, and when the rotary cutter 4 is rotated in this state, the feed shaft 8 rotates, and accordingly. The clamping jig 11 is transferred to the rotary cutter 4 side. Conversely, when the movable piece 24 is tilted in the Y' direction, the engagement between the thread groove 30 and the feed screw 7 (FIG. 7) is released, and even if the rotary cutter 4 is rotated, the clamping jig 11 is not transferred. It is also designed so that it can be pulled back to the right side in the drawing by hand.

In the present invention, when the fish A is cut by the rotary cutter 4 and its outer diameter becomes smaller, the rotary cutter 4 shown in FIGS. 7 and 8 can be moved toward the fish A by a drive body (not shown). There is. In the present invention, the rotary cutter 4 may be fixed and the fish pieces A may be moved toward the rotary cutter 4, or both the rotary cutter 4 and the fish pieces A may be brought closer to each other. The key is to make the rotary cutter 4 and the fish A relatively close to each other. The mechanism for this approach is not particularly limited.

The run-out stopper 6 shown in FIGS. 7 and 8 is used to prevent vibration, lateral wobbling, vertical runout, etc. of the fish-like material A during cutting. A steady rest hole 31 into which A can be inserted is formed. The swing stopper 6 may be of a type other than the one shown in the figure for the purpose of preventing the fish A from lateral swinging or vibration. It may be something that is forced. Moreover, it is sufficient if it is provided on the front side of the rotary cutter 4.

Although the fish segment A shown in the figure has a round bar shape, the fish segment A is not limited to this, and may be a conventionally existing spindle-shaped bonito flake, or any other suitable shape.

(Effects of the Invention) The fish cutting method of the present invention has the following effects.

Since a rotary blade 4 is used in which a cutting blade 3 is formed on the outer peripheral surface 2 of a rod-shaped, cylindrical, or disk-shaped base material 1 in which no blade protrusion hole is formed, cutting is performed using a conventional plate-shaped blade. Various drawbacks of the case are wiped out. In particular, in the present invention, since no blade protrusion hole is formed in the base material 1, there are various drawbacks of conventional cutting methods using a rotary cutter in which the cutting edge of a plate-shaped blade is protruded from the blade protrusion hole in the base material 1, for example. If the blade protrusion hole becomes clogged with shavings, powder, etc., it will be cleared away.

Since only one rotary blade 4 is rotated in a fixed direction, if the fish joint A is chipped, cracked, or torn, as in the case where two blade rollers j are arranged in parallel as shown in FIG. It is possible to cut extremely smoothly, and the above-mentioned drawbacks when using two blade rollers side by side are completely eliminated.

The rotary blade 4 that is rotated individually is a rotary blade 4 that has a cutting blade 3 formed on the outer peripheral surface 2 of a rod-shaped, cylindrical, or disk-shaped base material 1 in which no blade protrusion hole is formed. , as shown in Fig. 4, the planer blade a is attached to the plane holder d, which is recessed in the center, and is not rotated. It has never happened that it hits the central part of the fixture d that is not recessed and remains uncut.

Since the rear end of the fish A is clamped by the clamping jig 11 when the fish A is transferred, the fish A can be easily transferred continuously at a speed corresponding to the amount of rotation of the rotary blade 4. In addition, the fish A is stable during transportation and cutting with the rotary blade 4, and in particular, the shake and vibration of the fish A during cutting are reduced, making it easier to cut into a uniform shape. There is almost no chance that the knot A will be chipped and its fragments will get mixed into the thin shaved knot.

As the clamping jig is transported along the guide,
The transfer of the jig is stable, which in turn stabilizes the transfer of the fish flakes, and it is possible to obtain shaved flakes of a constant shape and thickness.

The transport body 5 moves at a speed corresponding to the amount of rotation of the rotary cutter 4.
Since the fish flakes A are continuously transferred and pressed against the cutting blade 3 of the rotary knife 4, the thickness of the shaved flakes to be cut is equal to that of the fish flakes. Feed amount S (cm/min) of A and rotary knife 4
It is determined by the relationship S/R with the rotation speed R (rpm). Therefore, by adjusting the S/R relationship, the thickness of the shavings can be easily adjusted to a desired thickness. Note that when the number of cutting edges 3 formed on the side end surface 2 of the base material 1 is n, the thickness of the cut knot is determined by S/R·n.

The outer circumferential surface B of the fish A is brought into contact with the cutting blade 3 of the rotary blade 4 formed on the outer circumferential surface 2 of the base material 1, and the outer circumferential surface B is cut. A shaved knot having a different shape from that in the case where the rotary cutter 4 is brought into contact with the rotary cutter 4 can be obtained.

Since the shake of the fish flakes A is prevented while cutting with the shake stopper 6, it is easier to obtain shaved flakes of a constant thickness and shape, and it is difficult for powder to come out and the fish flakes A to be chipped. Yield improves.
