【考案の詳細な説明】 本考案はロータリーレースの罫引き刃物装置に関するも
のである。[Detailed Description of the Invention] The present invention relates to a rotary lace scoring cutter device.

初て、既存のロータリーレースは、原木を回転せしめる
駆動力を、専ら該原木を支持するスピンドルから供給す
る形式であった為に、切削途上に於て原木が破損したり
、あるいは太い剥芯が残ったりする種々の不具合が発生
し、原木の利用率（歩留り）が極めて悪くなる欠点を有
していた。For the first time, with existing rotary races, the driving force to rotate the log was supplied exclusively from the spindle that supported the log, which caused damage to the log during cutting or thick cores. This has resulted in various problems such as residual wood remaining, resulting in an extremely poor utilization rate (yield) of logs.

そこで本出願人は先にベニヤレース（特願昭５２−６２
８８号、特開昭５３−９１４９９号公報）に開示する如
く、新たな構成に基づく新型ロータリーレースを提案し
、既存のロータリーレースの欠点を払底せんと図った。Therefore, the applicant first applied for veneer lace (Japanese Patent Application No. 52-62
As disclosed in JP-A-53-91499), we proposed a new type of rotary race based on a new configuration in an attempt to eliminate the drawbacks of the existing rotary race.

該新型ロータリーレースの大要は、既存のロータリーレ

来に比べて効果的な原木の切削を行う事ができるように
なった。The gist of this new type of rotary lace is that it is equipped with a rotating roll that pierces the log at a position similar to the position of the nose bar in existing rotary laces. Since power can be supplied from the outer periphery of the log close to the cutting edge of the cutting tool, the problems that occur with existing rotary laces are extremely unlikely to occur, making it possible to cut logs more effectively than before. .

てまで転用を図るには不向であった。On the other hand, as is well known, the end surface of raw wood is extremely irregular in shape, so a scoring tool device with a scoring tool is installed in the rotary race, and the end surface of the veneer veneer is formed while the veneer veneer is being ground. However, the ruling blade device in the existing rotary lace is a large and durable pressure member called a nose bar that is placed above the turret across a path of veneer. Since a pulling knife is attached and the rigidity of the powerful nose bar is used to support the blade-shaped scoring knife, it is geometrically and mechanically difficult to use it as is for the new rotary race. It is extremely difficult to use the above-mentioned blade-shaped ruled knife,
Each time it becomes damaged, it must be removed and re-sharpened, and it can only be used until the length becomes unsuitable for attachment, and the considerable length must be discarded. When adding up the cost required for re-polishing, the cost required for marking is relatively high, and it is not suitable for attempting to use it for other purposes without overcoming the above-mentioned difficulties.

面と共に説明すれば次の通りである。The purpose of this invention is to provide a scoring knife device suitable for the new type of rotary lace, and by making the scoring knife into a replaceable blade, that is, a small knife that can be replaced one after another without resharpening. As a result, the cost required for marking can be reduced, and the details thereof will be explained below with reference to the drawings.

出せしめる。The scoring knife device according to the present invention is illustrated in FIGS. 1 and 2, for example.
A rotary race as shown in the figure, that is, a rotary roll (symbol omitted) consisting of a large number of drive members 6 having a large number of protrusions 5 on the outer periphery arranged at appropriate intervals in the axial direction is used as a cutting blade 1. The outer periphery of the raw wood, which is substantially parallel to the cutting edge line of the cutting tool 1 and which is close to the cutting edge of the cutting tool 1 during cutting, is provided at a practical position, and a driving member (not shown) that drives the rotating roll is provided. (omitted), and a fixed bar 4' as a pressure member is connected to the drive member 6 of the rotating roll.
The device is attached to a rotary race arranged in at least a part (in the embodiment, all of the central part) of a plurality of spaces formed between the two spaces, and Figure 3a
, l), the creasing knife holder 4, which has a mounting hole 9 for the creasing knife 8 that forms the end surface of the veneer veneer cut from the log 2, is driven by the rotating roll. Of the plurality of spaces formed between the members 6, the space located near the end of the log is provided, and the space shown in FIG.
As is clear from FIG. 3C and FIGS. 4a, 1) and c, a replacement blade-like scoring knife 8 with the cutting edge 8'' facing in the direction generally opposite to the rotational direction of the log 2 is used to perform the scoring. It is removably attached to the mounting hole 9 of the drawing knife holder 4, and the cutting edge of the scoring knife 8 is made to protrude beyond the vertical line Y passing through the cutting edge of the cutting knife 1 as usual.

ベニヤ単板に所望の木口面が形成される。The scoring knife device according to the present invention is configured as described above, for example, in which as the log supported by the spindle of the rotary race rotates, the fishing stand to which the cutting blade is attached moves toward the axis of the log. Along with this, veneer veneers are sequentially cut from the raw wood, and rotating rolls,
Similar to the fixed bar etc., the scoring is performed by the scoring knife of the scoring knife holder that follows the movement of the fishing stand,
A desired end surface is formed on the veneer veneer.

着した罫引き刃物ホルダーを配備するものであるから、
従来の罫引き刃物装置の如き困難性を伴わずに何等支障
なく罫引き作用を機能させる事ができる。As is clear from the above, the scoring knife device according to the present invention has a veneer lace constructed as described above, and the scoring knife is attached to the groove-shaped space secured between the drive members of the rotating rolls. Because it is equipped with a ruled knife holder,
It is possible to perform the scoring function without any problems, without the difficulties of conventional scoring knife devices.

用上の効果は多大である。In addition, by making the scoring knife a small knife that can be replaced one after another without resharpening, so-called a replacement blade, the manufacturing cost can be reduced through mass production of a single product, and the wear cost of the scoring knife can be reduced. It is possible to reduce the cost required for re-polishing and reduce the cost required for re-polishing, and as a result, the cost required for marking can be reduced compared to the conventional method, which has a great practical effect.

く複数個配設しても差支えない。As is clear from FIGS. 1 and 3a and 3b, the ruled cutlery holder is configured such that the end is brought into contact with the outer circumferential surface of the raw wood by means such as slightly bending the bottom.
There is no problem in having it also have the function of a pressure member, and of course, if necessary, it is also possible to arrange a plurality of them as shown in FIG. 2.

また罫引き刃物を罫引き刃物ホルダーの装着孔へ着脱可

的である。In addition, when the scoring knife is removably attached to the mounting hole of the scoring knife holder, for example, as shown in FIG. For example, as shown in FIG. Even if a notch is provided that matches the back surface of the upper part of the mounting hole of the knife holder and the two are engaged, it is still possible to simply place the scoring knife on the seat of the scoring knife holder, as shown in FIG. 4a, for example. Even if the two are engaged, the important thing is to ensure that the scoring tool does not fall under its own weight, and that it does not shift, turn, or come off due to external forces such as the cutting blade or pressing force generated during scoring. It is preferable that no other fastening means be required, and it is effective to use an engagement form that is easy to attach and detach.
