この考案はロールコータに付設されるロール型
ドクタに関する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a roll-type doctor attached to a roll coater.
例えば、第２図に示すごときロールコータにお
いて、ベースロール１にウエブ２をはさんで金属
製のロール型ドクタ３が接当して塗工液４をウエ
ブ２の表面に一定量塗工する形態のものがある。
For example, in a roll coater as shown in FIG. 2, a metal roll-type doctor 3 is brought into contact with a base roll 1 sandwiching a web 2 to apply a certain amount of coating liquid 4 to the surface of the web 2. There is something like that.
そのロール型ドクタ３は、従来一般に第４図に
示すごとくベースロール１に接当するドクタ胴部
３ａの両端面からシヤンク部３ｂ，３ｂを突設し
てあり、このシヤンク部３ｂ，３ｂが軸受メタル
５，５で支持されるものとなつている。 Conventionally, the roll-type doctor 3 has shank parts 3b, 3b protruding from both end surfaces of the doctor body 3a which abuts on the base roll 1, as shown in FIG. It is supported by metals 5 and 5.
この種のロール型ドクタ３は塗工量を決定する
うえでドクタ胴部３ａの周面の研摩精度が厳しく
要求され、また芯振れをなくすためにシヤンク部
３ｂの周面の研摩精度も厳しく要求される。
This type of roll-type doctor 3 requires strict polishing accuracy on the circumferential surface of the doctor body 3a to determine the coating amount, and also requires strict polishing precision on the circumferential surface of the shank portion 3b to eliminate core runout. be done.
ところが、従来形態ではこれらの研摩作業は二
工程にわたつてそれぞれ別々に行われており、面
倒であるうえに、ドクタ胴部３ａとシヤンク部３
ｂとの研摩精度を同時に出すのが極めて困難であ
り、芯振れを生じやすかつた。 However, in the conventional configuration, these polishing operations are performed separately in two steps, which is troublesome, and also requires the doctor body 3a and shank portion 3.
It was extremely difficult to achieve polishing accuracy at the same time as polishing method b, and center runout was likely to occur.
この考案はかかる事実に着目して、一回の研摩
工程でドクタ胴部３ａと軸受メタル５，５への支
持部とが同時に高精度で研摩仕上げできて芯振れ
もないロール型ドクタを得ることを目的とする。 This invention focuses on this fact, and aims to provide a roll-type doctor in which the doctor body 3a and the supporting parts for the bearing metals 5, 5 can be simultaneously polished with high precision in one polishing process, and there is no center runout. With the goal.
すなわち、本考案では第１図に示すごとくドク
タ胴部３ａの軸受メタル５，５で支持される両端

ことを特徴とする。
That is, in the present invention, as shown in FIG. It is formed to have the same diameter as that of 3a. In other words, instead of eliminating the conventional doctor support shank parts 3b, 3b, the shank part 3
By increasing the total length of the doctor body 3a by the lengths b and 3b, both ends 3c and 3c of this doctor body 3a are formed.
is directly supported by bearing metals 5, 5.
以上のようにした本考案に係るロール型ドクタ
３によれば、研摩作業は従来の煩雑なシヤンク部
３ｂの研摩工程を省略できてドクタ胴部３ａの周
面の研摩工程だけで済み、ドクタ胴部３ａの周面

少ないものにできることになる。
According to the roll-type doctor 3 according to the present invention as described above, the conventional complicated process of polishing the shank portion 3b can be omitted, and only the process of polishing the circumferential surface of the doctor body 3a is required. By increasing the polishing precision of the peripheral surface of the portion 3a, it is also possible to reduce center runout.
第１図は本考案の実施例を示しており、この場
合のドクタ３は全長にわたつて等径ａのドクタ胴
部３ａを有し、該ドクタ胴部３ａの両端部３ｃ，
３ｃを軸受メタル５，５で支持し、両端部３ｃ，
３ｃ間の中間胴部がベースロール１に接触するも

FIG. 1 shows an embodiment of the present invention, in which the doctor 3 has a doctor body 3a having a constant diameter a over its entire length, and both ends 3c of the doctor body 3a,
3c is supported by bearing metals 5, 5, and both ends 3c,
The intermediate body between 3c is in contact with the base roll 1.
そして、ドクタ胴部３ａの一端面の中央に回転
操作用のシヤンク６が突設されている。このシヤ

ク６は使用目的からして従来の軸受メタル５，５
で支持されるシヤンク部３ｂに必要とされていた
ような研摩を要しないものである。 A shank 6 for rotational operation is provided protruding from the center of one end surface of the doctor body 3a. This shank 6 is used to reversely rotate the doctor body 3a in order to clean the lower circumferential surface of the doctor body 3a that comes into contact with the base roll 1 when it becomes dirty due to continued use. Therefore, this rotary operation shank 6 is different from the conventional bearing metals 5 and 5 due to its intended use.
This eliminates the need for polishing, which was required for the shank portion 3b supported by the shank portion 3b.

The roll coater targeted by the present invention is not limited to the form shown in FIG. 2. Web 2 on base roll 1
It is also possible to foresee a situation in which this information is not provided. In addition, for example, as shown in FIG.
A type of reverse roll coater that is rotatably driven at low speed through a doctor blade 7 to scrape off excess coating liquid on the doctor blade 3 is also covered.
