Description

  The present invention relates to an apparatus for manufacturing a cut joint, and a manufacturing method or a cutting method for a cut joint using the same.

  Conventionally, shaving clauses such as bonito have been manufactured by forming fish clauses and cutting fish clauses. When cutting fish sections, a cutting section manufacturing apparatus equipped with a rotating device is used. The rotating device includes a cutter disk having a cutting blade. When the blade disk rotates, the cutting blade cuts the fish nodes pressed against the blade disk.

When the blade disk rotates, frictional heat is generated between the blade disk and the fish node pressed against the blade disk. Further, when the cutting blade cuts the fish node pressed against the blade disk, cutting heat is generated between the cutting blade and the fish node pressed against the blade disk. The temperature of the cutting heat is higher than the temperature of the frictional heat. It is considered that this is because the resistance when the cutting blade presses the fish node pressed against the rotating disk is larger than the resistance when the rotating disk rubs.
Due to the frictional heat and the cutting heat, the temperature of the blade disc rises when the fish clause is cut. If the cutting of the fish clause is continued for a long time, the temperature of the blade disk increases.

  If the temperature of the blade disk is high, the color of the cut-off will be lost. In addition, the taste and incense of the shavings are impaired. For this reason, in order to maintain the quality of the shaving node, it is necessary to suppress an increase in the temperature of the blade disk.

The cutter disk can suppress an increase in temperature by lowering the peripheral speed of the cutter disk.
However, when the peripheral speed of the cutter disk is lowered, the speed of the cutting blade is lowered. If the peripheral speed of the cutter disk is lowered to a speed that does not impair the shavings, the cutting blade speed will be insufficient. For this reason, there has been a problem in that a cutting node manufactured by cutting a fish node is rounded.

Further, as an invention for suppressing an increase in the temperature of the cutter disk, there has been proposed an apparatus for manufacturing a cutting node equipped with a temperature control means for controlling the temperature of the blade disk so as not to rise above an appropriate temperature of the cutting node (Patent Document 1).
However, the temperature control means has a complicated mechanism such that a vacuum chamber is contained in the blade disk, alcohol or the like is sealed in the vacuum chamber, and a fan-type heat radiation member is attached to the center of the blade disk. Is what you need. For this reason, there is a problem in that the cost of the shaving section manufacturing apparatus itself is increased, and the maintenance of the shaving section manufacturing apparatus is troublesome.
In addition, the above-mentioned prior art documents do not disclose any data indicating improvement in terms of the gloss of the cut section, the improvement of the blade holding and the efficiency of the cutting operation, and how much improvement can be achieved. It is unknown.

  The purpose of the present invention is to improve the quality of the cutting edge such as Aozawa and to improve the durability of the cutting blade while suppressing the rise of the temperature of the cutter disk by incorporating a relatively simple mechanism into the manufacturing apparatus of the cutting edge. An object of the present invention is to provide an apparatus for manufacturing a shaving node capable of improving the performance.

  As a result of extensive studies by the present inventors in order to solve the above-mentioned problems, it has been found that an apparatus for manufacturing a cutting node in which the cutting blade tip of the cutting blade is coated with diamond-like carbon meets the object of the present invention, and completes the present invention. It came to.

That is, the present invention

The rotating device includes a cutter disk having a cutting blade,
An apparatus for manufacturing a cutting node is provided, wherein the cutting blade tip of the cutting blade is covered with diamond-like carbon.

Also, one of the present invention is
[2] Manufacture of a shank using the shank manufacturing apparatus according to [1] above, wherein the fish sword is brought into contact with the blade disk having a peripheral speed in the range of 3.5 to 4.0 m / s. A method is provided.

Also, one of the present invention is
[3] Cutting of a cutting node using the cutting node manufacturing apparatus according to the above [1], wherein a fish node is brought into contact with the blade disk having a peripheral speed in a range of 3.5 to 4.0 m / s. A method is provided.

Also, one of the present invention is
[4] The apparatus for manufacturing a shaving joint according to the above [1], wherein the peripheral speed of the cutter disk is in a range of 3.5 to 4.0 m / s.

  According to the apparatus for manufacturing a shaving knot of the present invention, even if the cutting of a fish knot is continued for a long time, diamond-like carbon has a low friction coefficient and excellent slidability, so that generation of cutting heat can be suppressed. it can. Therefore, the temperature rise of the cutter disk can be suppressed and the variety of shaving nodes can be improved.

In addition, when cutting a fish knot, if the cutting edge of the cutting blade is low, the fish knot that can not be cut well will not be a knot, but will be powdered, but diamond-like carbon has high hardness and excellent wear resistance. An apparatus for manufacturing a cutting node having a cutting blade whose tip is coated with diamond-like carbon can suppress the generation of powder due to its good sharpness.
In addition, when the cutting edge is low in sharpness, a pattern called chatter occurs in the shaving node.Diamond-like carbon has high hardness and excellent wear resistance, so a cutting blade whose tip is covered with diamond-like carbon is used. The manufacturing apparatus of the shaving node which it has can suppress generation | occurrence | production of chatter with the favorable sharpness.

  In addition, since diamond-like carbon has high hardness and excellent wear resistance, a cutting blade coated with diamond-like carbon has excellent durability.

  Hereinafter, the present invention will be described based on examples, but the present invention is not limited to the following examples.

[Performance evaluation of shaving section manufacturing apparatus 100 according to embodiment 1]
The cutting blade tip 1 of the cutting blade 200 is coated with diamond-like carbon (manufactured by Japan IT Corporation).
The room temperature is 18.5 °, and the peripheral speed of the cutter disk 220 is 4.8 m / s.
A performance evaluation test of the shaving clause manufacturing apparatus 100 according to Example 1 was performed.

(1) Temperature of Cutlery Disk The temperature of the cutlery disk 220 was measured using the shaving node manufacturing apparatus according to Example 1.
For measuring the temperature, an infrared radiation thermometer (manufactured by Sato Meters Co., Ltd., trade name: SK-8700II) was used. The change in temperature is shown in Table 1 and FIG.
Moreover, the average value of the temperature of the cutter disk 220 is calculated every day, and changes in the temperature of the cutter disk 220 are shown in Table 2 and FIG. The cutting time is 8 hours per day.
As can be seen from Table 1 and FIG. 6, when cutting is started, the temperature of the cutter disk 220 rises due to cutting heat and frictional heat. Between the start of cutting and 180 minutes, the temperature of the cutter disk 220 was in the range of 27.0 to 36.5 °, and the temperature was generally in the above range even after 180 minutes.
Moreover, as can be seen from Table 2 and FIG. 7, the temperature of the cutter disk 220 increases as the days go on. This is because, when the cutting blade tip 1 is worn, the resistance when cutting the fish salmon increases, and the temperature of the cutting heat increases.

上記Ｌ^*、ａ^*及びｂ^*の値の測定に際しては、削り節を粉末状にした上で、色彩色差計を使用して測定した。
その上で、上記数式に基づき色度の値を得た。
結果を表３と図８に示す。 (2) Color of cut knot The cut knot manufactured using the knot manufacturing apparatus according to Example 1 was measured using a color difference meter (trade name: CR-300, manufactured by Konica Minolta Co., Ltd.).
The following L ^* , a ^*, and b ^* measured using a color difference meter are values of the L ^* a ^* b ^* color system standardized by the International Commission on Illumination (CIE) in 1976.
When quality deterioration occurs due to oxidation or the like, the shaving node has a brownish color as a result of the red color becoming weaker and the yellow color becoming stronger. Therefore, it is considered that the shaving node has a strong red color and a weak yellow color.
Chromaticity is a unique index defined by the following mathematical formula, and the larger the chromaticity value, the better the chromaticity.
The value of arctan (arc tangent) is in degrees.

When measuring the values of L ^* , a ^*, and b ^* , the shaving node was powdered and then measured using a color difference meter.
Then, chromaticity values were obtained based on the above formula.
The results are shown in Table 3 and FIG.

(3) Powder ratio of cut joints Using the cut joint manufacturing apparatus according to Example 1, the powder content when manufacturing cut joints was measured.
The powder content was measured according to the Japanese Agricultural Standard. That is, after the sample was obtained using the apparatus for manufacturing a shaving joint according to Example 1, all the samples were sieved using a test sieve having an opening of 850 μm as defined in JISZ8801-1, and the weight of the sample that passed through the sieve The percentage of the sample to the sample weight was defined as the powder content.
The results are shown in Table 4 and FIG.

(4) Number of worn portions of the cutting blade The worn portion of the cutting blade tip 1 was observed using a microscope. The magnification of the microscope is 200 times.
When the fish knot is cut, wear points are generated at the cutting blade tip 1, and the degree of wear of the cutting blade tip 1 can be grasped by counting the number of wear points.
When counting the number of wear spots, one having a width of 15 μm and a depth of 15 μm or more was counted as one. Then, the cutter disk 220 has 14 to 16 cutting blades 200, and after counting the number of wear portions for all the cutting blades 200, the number of the cutting blades 200 is divided by the number of cutting blades 200, and the number of cutting blades 200 is determined. The average value of the number of wear spots was determined.
The results are shown in Table 5 and FIG.
As can be seen from Table 5 and FIG. 10, the number of wear points increased and then decreased. This is because the number of wear points increases when cutting fishfish is continued, but when the number of wear points reaches a certain number, the wear points are now connected to each other.
If the number of wear points starts to decrease, the cutting blade must be replaced. This is because the sharpness of the cutting blade is significantly reduced.

[Comparative Example 1]
In the case of Example 1, except that a cutting blade manufacturing apparatus having a normal blade (manufactured by Sumitomo Electric Hardmetal Co., Ltd., trade name: ultrafine alloy “A1”) whose tip is not coated with diamond-like carbon is used. The test was performed in the same manner as in Example 1.
The results are shown in Tables 1 to 5 and FIGS.
As can be seen from Table 1 and FIG. 6, according to the cut knot manufacturing apparatus according to Comparative Example 1, the temperature of the blade disc rises by about 10 ° in about 10 minutes after the start of cutting. After that, the temperature of the cutter disk continues to rise, and it can be confirmed that the temperature is kept high as compared with the case of Example 1. And as can be seen from Table 2 and FIG. 7, it can be confirmed that the temperature of the blade disc continues to maintain a high temperature as compared with the case of Example 1 even when days are repeated.
Further, as can be seen from Table 3 and FIG. 8, according to the cutting knot manufacturing apparatus according to Comparative Example 1, the temperature of the cutter disk is high, so that the chromaticity value is small compared to the case of Example 1, and It can be confirmed that the color is inferior.
Further, as can be seen from Table 4 and FIG. 9, according to the cut knot manufacturing apparatus according to Comparative Example 1, it can be confirmed that the powder ratio is large and contains much powder as compared with Example 1.
Further, as can be seen from Table 5 and FIG. 10, according to the cutting knot manufacturing device according to Comparative Example 1, the number of wear points increased rapidly, and turned to decrease on the third day, and the cutting blades had to be replaced. I can confirm that. In the case of Example 1, it is the fifth day that the number of wear spots starts to decrease, and the cutting-joint manufacturing apparatus according to Comparative Example 1 is more durable than the case of Example 1. It can be confirmed that it is inferior.

  According to the apparatus for manufacturing shavings of the present invention, it is possible to improve the quality of shavings such as various colors and to improve the durability of cutting blades while suppressing the rise of the temperature of the cutter disk only by incorporating a relatively simple mechanism. It becomes possible to improve the property.
