Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cutter for cutting fish flakes such as bonito flakes and mackerel flakes, which is used when cutting large quantities of fish flakes such as bonito flakes and mackerel flakes in a factory.

(Conventional technology) When used in cooking, shavings affect the quality of soup stock,
It is desired that the food be as thin as possible in terms of texture when eaten, and that be uniform in thickness and shape.

Recently, kerifobushi is packaged in several grams (the amount that is consumed at one time in a typical household), but in this case as well, the shape, size,
It is desired that the thickness etc. be uniform. Furthermore, in this case, it is desirable that the once cut bonito flakes be of a size that can be immediately packaged in bags without the need for secondary processing.
If shaved bonito flakes can be packaged as is, the time that bonito flakes are exposed to the air will be shortened, and the flavor of bonito flakes will be less likely to be lost due to oxidation.

Furthermore, in order to prevent the flavor of the dried bonito flakes from being impaired, it is necessary to minimize the frictional heat generated during cutting of the dried bonito flakes.

Conventionally, there have been cutting devices of this type as shown in FIGS. 1 and 2.

The cutting device shown in FIG. 1 has a planer blade c attached to a cutting table a, and the cutting device shown in FIG. 2 has a planer blade c attached to a rotary plate b.

To cut the fish flakes d using the cutting device shown in Figure 1, press the fish flakes d against the planer blade c, move the fish flakes d back and forth, and to cut the fish flakes d using the cutting device shown in Figure 2, rotate the fish flakes d. Rotate the board to rotate the planer blade c, and press the fish flakes d against the planer blade c.

In addition, in the past, there were blades with a spiral shape like the rotary blade of a pencil sharpener, such as the blade of Utility Model Application Publication No. 4445 of 1932, and the blade of Utility Model Application Publication No. 4445 of 1932,
There were also blades with curved blades in the circumferential direction of the cylindrical base material, such as the blade of No.

Furthermore, there were also bonito flaking machines such as Utility Model No. 46-11028 and rotary bonito flaking machines such as Utility Model No. 47-41392.

(Problems to be Solved by the Invention) Since the cutting devices shown in FIGS. 1 and 2 use a planer blade c, they have the following problems.

It is easy for shavings and cutting powder to become clogged between the planer blade c and the rotary plate b to which it is attached. Moreover, since the thickness of the keratin knots differs before and after they are clogged, it is not possible to obtain keratin knots with a constant thickness. In addition, if the kerifubushi becomes clogged, the blade becomes dull and unreasonable force is applied to the blade, causing it to break.
The rotating plate becomes distorted, and as a result, the thickness and shape of the cut joints become increasingly uneven.

It is unhygienic when dried bonito flakes become clogged, and this is unfavorable in terms of food hygiene, especially during the rainy season or in a hot and humid work environment, as it contributes to bacterial growth.

Planer blades C have high cutting resistance and are subject to severe wear, and even carbide blades wear out in about three days in factories that mass-produce shavings. As a result, the surface of the kerifobushi loses its luster.

Since the planer blade c is subject to severe wear, the protrusion of the planer blade c must be adjusted approximately every 10 minutes in order to uniformly cut the keburu to a thickness of, for example, 2/100 mm. However, in order to do this, it is necessary to stop the milling machine and stop the cutting operation, and in this case, the greater the number of planer blades c attached to the rotary plate, the longer the length of the planer blade c. The longer it is, the longer it takes to adjust, which significantly reduces work efficiency and productivity.

If the planer blade c is long, it is difficult to make it protrude uniformly over its entire length. In addition, if there are many blades, only one blade may protrude extremely, and in this case, the fishbushi d is strongly pressed only against that blade, and the other blades are not sufficiently pressed, reducing cutting efficiency. . Additionally, unreasonable force is inevitably applied to the extremely protruding blade, which distorts the disk, which in turn results in uneven thickness and shape of the shavings.

It takes three years of experience to be able to adjust all the planer blades uniformly, and even for an experienced person, it takes about three to five minutes on a planer with 16 blades.

Even if they are experts, they make adjustments based on their intuition, so there is considerable variation in the amount of time they make adjustments and depending on the sharpening machine they are adjusting, and even more so, if the person making the adjustment changes, there will be variations even with the same sharpening machine. As a result, the thickness of kerifobushi varies, and the actual situation is that the thickness of kerifobushi currently on the market varies over a wide range from 2/100mm to 10/100mm.

Replacing the planer blade c takes much more time than adjusting it, and on a 16-blade sharpener it takes 15 to 20 minutes.
It takes minutes.

In addition to the above drawbacks, the cutting device shown in FIG. 2 also had the following problems.

Because the spring e presses the fish buds d against the planer blade c, the planer blade c may wear out.
When the fish section d becomes thinner due to cutting, the spring e stretches accordingly and the pressing force becomes weaker. Therefore, since the force with which the fish flakes d are pressed against the planer blade c is not always constant, even if the protrusion of the planer blade c is adjusted to be constant, the cutting will not be done to a constant thickness.

A planer blade c is used in a sharpening machine using a spring e.
Whether the cutting quality is good or bad, the fish pieces d are pressed against the planer blade c, so if the planer blade c becomes difficult to cut, the fish pieces d are forcibly cut.
As a result, not only is the force applied to the planer blade c and the wear of the planer blade c becomes even more severe,
The rotating plate may even become distorted. Therefore, it becomes increasingly difficult to cut to a constant thickness, and the cut knots turn into powder, resulting in poor yield. Furthermore, if the thickness of the dried bonito flakes is uniform, it can be weighed and filled into bags etc. accurately and in a short time, but if it is uneven, this cannot be done and the weighing process becomes troublesome. As a result, the time when the dried bonito flakes are exposed to air becomes longer, which impairs the flavor.

Fish flakes d, which are pressed under normal pressure by spring e, come into contact with rotating plate b between planer blades c, so both fish flakes d and rotating plate b have frictional heat, and especially the rotating plate The temperature can reach 60℃ to 80℃. As a result, the dried bonito flakes may oxidize and lose their flavor.
The gloss will be lost and the quality will deteriorate.

When cutting with a planer blade c, the cut kezubu becomes long like a planer blade, and if left as is, it will be too large to be a keizushi, so once it has been cut, it must be pounded or kneaded to make it smaller to the same size. Must be. Not only does this work require a lot of effort, but the flavor of the bonito flakes is lost as they are exposed to air during the process, and the yield is also poor due to the powder produced by pounding and kneading.

In the case of the blade of Utility Model Application Publication No. 4445 of 1938, the shape of the blade is spiral like the rotary blade of a pencil sharpener, so the sharpener cut by the rotary blade is similar to that of a pencil. It was curled up in a spiral like shavings, and the shape and thickness were uneven, so it was not a shape that could be sold as shavings, and it had almost no commercial value as shavings.

In addition, in the case of the cutter of Utility Model Publication No. 1983-69482, the blade is curved in the circumferential direction of the cylindrical base material, so the shavings cut by this rotary cutter are also
Although it is not as sharp as the one cut with a knife in Utility Model Application Publication No. 4445, it is curved and curled up, and the shape is uneven in thickness, so it is not a shape that can be sold as a shaved bushi. It had almost no commercial value as shavings.

The katsuobushi shaving machine of Jitsugan No. 11028/1976 has a helical blade (spiral like the blade of a pencil sharpener), so when it cuts the bonito flakes, the resulting shavings are written in a cursive manner. It ends up curling up into a spiral like shavings, and it becomes a product with no commercial value.

Although the rotary bonito flakes cutting machine of Utility Model Publication No. 47-41392 discloses an intermittent mechanism, it is basically a machine with a planer blade attached to a mounting hole formed in a disk, so Figures 1 and 2. It has the same drawbacks as kezuribushi.

(Object of the Invention) The object of the present invention is to provide a cutter for cutting fish and fish pieces that does not have any of the above-mentioned problems.

(Means for solving the problem) The knife for cutting fish and fish of the present invention has the following features as shown in FIG.
Two or more rows of protrusions 7 are formed on the circumferential surface 2 of the base material 1 having a circumferential surface 2 from one end 2a in the axial direction of the base material 1 to the other end 2b, and each protrusion 7 is interrupted by a notch 8. A large number of interrupted blades 3 are formed, and the interrupted blades 3 of the protruding rims 7 in appropriate rows among the protruding rims 7 are formed so that no uncut parts are left on the cut pieces d cut by the interrupted rims 3. The shavings cut by the intermittent blades 3 of the respective protrusions 7 are shifted in the arrangement direction from the position of the interrupted blades 3 of the protrusions 7 in an appropriate row, and the cutting joints cut by the intermittent blades 3 of the respective protrusions 7 enter forward of the respective protrusions 7 in the rotational direction. A relief groove 5 is formed along each protrusion 7.

(Function) To use the knife for cutting fish and fish of the present invention, a rotary shaft such as a reducer is inserted and fixed into the shaft hole 6 of the base material 1, and the reducer is rotated to rotate the rotary knife. Then, the fish pieces d to be cut are brought into continuous contact with the interrupted blade 3 as shown in FIG. 3B. As a result, the fish d is cut into a small piece having the same width as the blade width of the interrupted blade 3.

Further, in the present invention, the interrupted blades 3 of the protrusions 7 in appropriate rows
is shifted in the longitudinal direction of the protrusion 7 (the direction in which the intermittent blades 3 are arranged) than the intermittent blades 3 of the protrusion 7 in other rows, so that each protrusion 7 is separated from one axial end 2a of the base material 1 to the other. Even if they are formed straight toward the ends 2b, the fish segments d do not hit the interrupted blades 3 of adjacent protrusions 7 at the same time. Therefore, the cutting resistance is low, and the interrupted blade 3
There is no stress on the blade, and there is less wear and damage to the blade.
The sharpness is also less likely to deteriorate.

Further, in the present invention, since the relief groove 5 is formed along each protrusion 7 forward of each protrusion 7 in the rotational direction, the scraped piece cut by the interrupted blade 3 is formed in the relief groove 5.
The kerifushi that is cut first does not get in the way of the kerifushi that is cut later.

(Example) The knife shown in FIG. 3 as an example of the knife for cutting fish and fish of the present invention has a straight or almost straight (somewhat straight) shape on the circumferential surface 2 of a cylindrical base material 1 having a shaft hole More than ten rows of curved ridges 7 are formed, and notches 8 are made at regular intervals at the tip of each ridge 7 to form an interrupted blade 3.

As clearly shown in FIG. 3B, the protrusions 7 are all formed obliquely in the same direction from one end 2a in the axial direction of the circumferential surface 2 to the other end 2b. This prevents the fish joints d from hitting the intermittent blades 3 of the respective protrusions 7 at the same time during cutting, reducing cutting resistance and preventing strain on the intermittent blades 3. This protrusion 7 may be formed completely straight from one end 2a of the circumferential surface 2 in the axial direction to the other end 2b.

If the protrusion 7 is made oblique or straight as described above, the shavings cut by the interrupted blades 3 of the protrusion 7 will be spirally round like pencil shavings cut with a spiral knife. It is flat, slender, and uniform in shape, rather than being curved, curled, and curled up, like when cutting with a blade that curves in the circumferential direction of the base material. , it becomes shaved bonito with a certain thickness and has high commercial value.

Notches 8 are formed at the tip of each protrusion 7 at regular intervals, and interrupted blades 3 are formed intermittently by the notches 8. Moreover, among the intermittent blades 3 of each protrusion 7, the intermittent blades 3 of adjacent protrusions 7 are shifted from each other in the longitudinal direction of the protrusion 7 (the direction in which the intermittent blades 3 are arranged). In this case, the purpose of shifting the intermittent blades 3 is to prevent uncut parts from being left on the fish joints d cut by the intermittent blades 3, so the arrangement is not necessarily shifted between adjacent interrupted blades 3, but with the The intermittent blades 3 of appropriate protrusions 7 may be shifted from the positions of the intermittent blades 3 of other protrusions 7, such as every other or every second protrusion 7.

Reference numeral 5 in FIG. 3 indicates a relief groove formed forward of the cutting edge 4 of the intermittent blade 3 of each protrusion 7 in the rotational direction, and the shavings cut by the respective interrupted blades 3 are cut by the rotation of the fish cutting blade. It is designed to be pushed in.
This relief groove 5 is formed long along the arrangement direction (projection 7) of the intermittent blades 3. If the relief groove 5 is deep, the cut knots to be cut can fully enter into it, resulting in a long cut knot; if it is shallow, the cut knots to be cut cannot fully enter into it, so they break on the way and the cut knots become longer. length becomes shorter.

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

Since it does not use a plate-shaped knife, the first
The conventional cutting device shown in Fig. 2, Utility Model Act 47-
Various drawbacks of the rotary bonito flaking machine No. 41392 have been eliminated.

If the fish d is pressed little by little against the interrupted blade 3, it can be cut as thin as 1/100 mm.

Since the interrupted blade 3 is interrupted by the notch 8,
The cut joint to be cut is not wider than the blade width of the interrupted blade 3. Therefore, by narrowing the blade width of the intermittent blade 3, it is possible to obtain a shavings that can be packed into bags without secondary processing, and there is no need to perform secondary processing such as rolling or pounding to break it into small pieces as in the past. . As a result, work efficiency is greatly improved, less powder is generated, and yields are improved, and the product can be packed into bags as is, which shortens the time it is exposed to air and reduces quality deterioration.

Since the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the intermittent blades 3 of the protrusions 7 in other rows, the entire cutting surface of the fish joint d is cut without leaving any uncut parts during cutting. Ru.

The intermittent blades 3 are interrupted by notches 8, and the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the intermittent blades 3 of the protrusions 7 in other rows, so that fish Intermittent blade 3 with a plurality of protrusions 7 on the cutting surface
rarely occur at the same time. Therefore, the cutting resistance of the interrupted blade 3 is small, no stress is applied to the interrupted blade 3, and wear and damage of the interrupted blade 3 are reduced. Also,
Since the cutting quality is also less likely to deteriorate, the thickness and shape of the cut pieces obtained by cutting become almost constant.

Since the relief groove 5 is formed, the cut kerifobushi can be pushed by the rotation of the cutter for cutting fish pieces and enter the relief groove 5, and as a result, the cut kerifobushi will be broken into short pieces. The length is constant depending on the depth of the relief groove 5. Therefore, it is possible to obtain a shavings having substantially constant thickness, shape, length, etc.

Since the intermittent blades 3 are formed on the protrusions 7, when the intermittent blades 3 are worn out due to use, the protrusions 7 can be repeatedly polished to form the intermittent blades 3, allowing for long-term use.
