及びその製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inking roller for a printing machine and a method for manufacturing the same, and more specifically, to a keyless inking system, that is, a blade working in cooperation with a doctor blade. The present invention relates to a roller to be used in a system in which excess ink on a surface is scraped off and a fixed amount of ink remaining in a recess is supplied, and a method for manufacturing the roller.

照）。(Prior Art) As a roller capable of supplying a fixed amount of ink in cooperation with a doctor blade, a mesh roller having a large number of fine fixed cells engraved on its peripheral surface is conventionally known (for example, JP-A-58-58). 42463, 58-56856, 61-181645).

減少して印刷に十分なインキ供給ができなくなり、やが
て、使用不可能となる表面的一回性の限界があった。(Problems to be solved by the invention) The mesh roller used for the conventional keyless inking requires a special cell processing technique for regularly arranging a large number of extremely precise and substantially fixed cells on the surface, and further, Even if the mesh roller is installed, the mesh roller will be worn by the doctor blade in the operating state, and the mesh roller surface will be worn away over time and the cells will gradually become shallower. Insufficient ink supply became impossible, and eventually there was a limit of superficial one-time property which made it unusable.

ローラー表面に残留させ得るものではなかった。On the other hand, conventionally, a roller whose surface is formed of a mixture of an inorganic powder and a synthetic resin can increase the surface hardness by containing an inorganic powder, so it is presumed that it is effective in improving wear resistance. However, it was not possible to bring the doctor blade into contact with the roller surface to scrape off excess liquid such as ink adhering to the roller surface and leave a substantially constant amount of liquid on the roller surface.

を再生することは不可能であった。Further, on the other hand, conventionally, in a roller in which a continuous and / or non-continuous hard band line in a direction non-perpendicular to the axis of the roller is arranged on the peripheral surface portion of the roller, the peripheral surface is in contact with a doctor blade. When rotating, the position of the band contacting the tip of the doctor blade constantly moves with the rotation, so the doctor blade does not wear unevenly and wears evenly and withstands long-term use. Not only that, the rate at which the soft peripheral surface portion sandwiched between the strips of the roller is worn by the pressure contact of the doctor blade is reduced. Therefore, it is clear that when the conventional cell processing is applied to the soft peripheral surface, the reduction rate of the cell volume is reduced, but it is impossible to regenerate the cell as the wear progresses. Met.

を超えることができなかった。In short, in the conventional technique, the cell processing for ink supply to the peripheral surface of the inking roller is a superficial one-time process, and as soon as the volume of the cell in use reaches a predetermined weight reduction value due to abrasion, that The roller was no longer usable and the abrasion-resistant means on the roller circumference could not exceed its limit value.

空体が露出している。(Function) The inking roller according to the present invention has a structure in which a large number of micro hollow bodies are dispersed and incorporated in a base material forming the ink receiving layer, and the shell of the micro hollow body is already formed on the surface of the ink receiving layer. The layer is removed to expose a semi-open micro hollow body which is semi-open in a concave shape.

される。In this state, ink is supplied to the peripheral surface of the inking roller, and a doctor blade is brought into contact with the surface of the ink receiving layer to scrape off excess ink.
The semi-open micro hollow body on the surface of the ink receiving layer acts as if it were an ink holding cell and retains the ink retained in the hollow body, so that a certain amount of ink remains in the ink receiving layer Ink is supplied toward the plate.

一方、これまで活躍していた半開形微小中空体は摩滅す
る。On the other hand, in the inner part of the ink receiving layer, a plurality of micro hollow bodies that are still sealed stand by, and they are accompanied by abrasion of the roller peripheral surface due to friction with the doctor blade, The shell layer of the micro hollow body is sequentially removed from the side closer to the surface, and gradually grown into a semi-open micro hollow body that is semi-opened in a concave shape, which is useful for the next ink supply, while it has been active until now. The semi-open micro hollow body that had been worn out is worn away.

能が承継される。Thus, in the present invention, the semi-open micro hollow body on the roller surface, that is, the depression similar to the ink retaining cell, wears out the thickness of the base material forming the ink receiving layer,
The functions are successively generated one after another, and the functions are inherited while changing generations.

インキ受理層の摩耗が著しく軽減される。On the other hand, in the present invention, adjacent to the ink receiving layer having the above-mentioned action, a hard strip line is provided in a non-perpendicular direction to the axis of the roller, and since the strip line bears the pressing force from the doctor blade, Wear of the ink receiving layer due to contact with the doctor blade is significantly reduced.
更に、本発明では、耐摩耗手段を、最少の占有面積しか
有しない帯線としたので、ローラーの全周面に対するイ
ンキ受理層の占有面積が最大に確保される。Further, in the present invention, since the abrasion-resistant means is the band line having the smallest occupied area, the occupied area of the ink receiving layer with respect to the entire peripheral surface of the roller is secured to the maximum.
更に、本発明では、耐摩耗手段を、最小の占有面積した

ドの長期使用にも役立つ。Further, in the present invention, although the abrasion-resistant means is a band line that does not have a minimum occupied area, the arrangement direction of the band line is not perpendicular to the axis of the roller. In connection with this, since the position of the band line contacting the doctor blade constantly moves, the doctor blade is not unevenly worn and uniformly worn, and therefore, it is also useful for long-term use of the doctor blade.
また、本発明には、インキ受理層に硬質粉末を混在させ

のようにインキ受理層に摩耗作用が働くときに、表面に

長くすることが可能となる。Further, in the present invention, when a hard powder is mixed in the ink receiving layer, when the abrasion action works on the ink receiving layer like scraping off of excess ink by a doctor blade, the hard powder exposed on the surface bears this. Therefore, it is possible to suppress the abrasion of the ink receiving layer and prolong the life of the inking roller.

る。Further, some materials are mixed in the ink receiving layer of these inking rollers, but if the mixed state of each material is kept substantially evenly distributed, even if the ink receiving layer is worn out, the ink receiving layer will be in substantially the same state. Is retained on the surface of the ink receiving layer and does not cause a difference that affects the amount of ink retained and abrasion resistance, and has almost the same performance as an inking roller for a long period of time before the ink receiving layer is completely worn. To maintain.

たり保証される。When the ink is supplied to the peripheral surface of the roller 1, the ink is entangled with the surface of the ink receiving layer 4 and the surface of the strip 3, and
Excess ink is scraped from both surfaces by a doctor blade (not shown). Then, the semi-open micro hollow body 6 on the surface of the ink receiving layer acts as if it were an ink retaining cell, and retains the ink retained in the hollow body, so that almost constant ink remains in the ink receiving layer 4. , The residual ink is supplied toward the plate surface. When abrasion occurs on the surface of the ink receiving layer 4 due to the above-mentioned repetition,
As the abrasion progresses, the shell layer of the micro hollow body 6 is sequentially removed from the side closer to the surface of the micro hollow body 6 which is still sealed in the inner depth of the ink receiving layer 4, and the micro hollow body 6 is half-opened. , The semi-open micro hollow body, which had been active until now, is worn out and disappears while it is responsible for the next ink supply. The progression of this series of wear is significantly hindered by the action of the hard band line 3, so that the ink supply performance of the inking roller 1 is guaranteed for a long time.

らせることを可能にした。(Effects of the Invention) As described in detail above, the inking roller according to the present invention and the inking roller according to the method of the present invention include an ink receiving layer having a special structure in which a large number of minute hollow bodies are incorporated in a substrate, and the ink thereof. Since it is composed of a hard band wire that reduces the abrasion of the receiving layer, it is of course possible to perform an ink supply action similar to the ink retaining action of the cell in the conventionally well-known mesh roller, and to the progress of the abrasion of the ink receiving layer. Along with this, even if the semi-open micro hollow body that had been active up to now is worn out, the micro hollow body sealed inside is opened by the progress of the wear itself, and the ink supply is continuously maintained. , This succession function is continued until the thickness of the base material forming the ink receiving layer is worn out. In this respect, there is a marked difference as compared to conventional mesh rollers having a superficial singularity limit. However, the softness of the base material itself forming the ink receiving layer in the present invention is recognized as a difficulty that can not hinder the progress of the abrasion, in the present invention, the hard band line adjacent to the ink receiving layer. It has been possible to solve it and delay the progress of wear.
また、インキ受理層を形成する基材内に硬質粉末を混入
することによっても、上記摩耗の進行をおくらせること

ーに比しコスト低廉に提供し得る。Furthermore, the inking roller according to the present invention and the method according to the present invention does not require special cell processing or special coating treatment like the conventional mesh roller, and the micro hollow body is mixed in the base material of the ink receiving layer. Since this can be achieved by a simple operation and a constitution of performing it, it can be provided at a lower cost than a conventional mesh roller.
