本発明はベニヤレースに関し、さらに詳しくは、原木の
切削時におけるスピンドルのたわみを大幅に減少せしめ
る部材を設けたベニヤレースに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a veneer lace, and more particularly to a veneer lace provided with a member that significantly reduces deflection of a spindle during cutting of raw wood.
従来、ベニヤレースにおいては、原木の両端面をスピン
ドルで支持した状態で原木を回転させ刃物により切削す
ることが行なわれている。Conventionally, in the production of veneer lace, the raw wood is rotated with both end surfaces of the raw wood supported by spindles and cut with a blade.
しかしスピンドルの直径が小であると、刃物の切削力及
びプレッシャーバー等の原木への押圧力によってスピン
ドルが刃物とほぼ反対の方向へたわんでしまい切削され
た単板の厚さが不揃いで使用不能となるのであり、特に
この傾向は原木の直径が大である時は少ないものの、小
となると顕著となるのである。それ故スピンドルの直径
を大とせざるを得ないが、大とするとスピンドルの直径
より小さい部分の原木は、刃物又は刃物台がスピンドル
に当たるため切削することができず、剥芯径が大きくな
り歩留りを低下させる原因となっていたのである。However, if the diameter of the spindle is small, the cutting force of the blade and the pressure of the pressure bar against the raw wood will cause the spindle to bend in the direction almost opposite to the blade, resulting in uneven thickness of the cut veneer, making it unusable. In particular, this tendency is small when the diameter of the log is large, but becomes noticeable when the diameter is small. Therefore, the diameter of the spindle has to be increased, but if the diameter of the spindle is increased, the part of the log that is smaller than the diameter of the spindle cannot be cut because the cutter or turret hits the spindle, and the diameter of the core to be stripped increases, which reduces the yield. This was the cause of the decline.
このような問題の対策として大径のスピンドルと小径の
スピンドルとを一体化して同じ回転軸に備えたダブルス
ピンドルも用いられているが、原木の直径が小となって
大径のスピンドルを後退させた後小径のスピンドルのみ
で切削を行なう場合には前記と同様の問題が生じていた
のである。As a countermeasure to this problem, double spindles have been used in which a large-diameter spindle and a small-diameter spindle are integrated and installed on the same rotating shaft, but as the diameter of the log becomes smaller, the large-diameter spindle is forced to retreat. If cutting is then carried out using only a small diameter spindle, problems similar to those described above occur.
特に最近は原木事情が悪化し平均的に直径が小さい原木
を使用せざるを得なくなってきており原木使用量に対す
る剥芯の量の割合は当然に高くなり、また間伐材を使用
することも必要となってきていることから前述のことは
大きな問題となっていたのである。In particular, recently the situation with logs has worsened, forcing us to use logs with a smaller diameter on average, and the ratio of the amount of cored wood to the amount of logs used has naturally increased, and it is also necessary to use thinned wood. As a result, the above-mentioned problem has become a big problem.
本発明はこの様な問題を解決するべく、ベニヤレースに
おいて、原木を支持しつつ回転するスピンドルに対し、
原木に対する刃物の当接部位とほぼ反対側の前記スピン
ドルの周面の所要部位に当接し、原木切削時に生ずるた
わみに抗して、スピンドルを押圧支持する支持部材を設
けたものである。In order to solve such problems, the present invention provides a spindle that rotates while supporting logs in a veneer race.
A support member is provided that contacts a predetermined portion of the circumferential surface of the spindle on the opposite side from the contact portion of the cutter against the raw wood, and presses and supports the spindle against the deflection that occurs when cutting the raw wood.
本発明のベニヤレースは、前記のような構成であるので
、原木を支持するスピンドルが刃物の切削力を受けて、
スピンドルに原木に対する刃物の当接部位とほぼ反対側
にたわませる力が働いても、スピンドルの周面の所要部
位に当接して設けられた支持部材によってスピンドルは
たわみに抗して押圧支持されるのでたわみ量は小となり
、又刃物側には支持部材が存在しないので刃物はスピン
ドルの側まで接近して原木を切削できる。Since the veneer lace of the present invention has the above-described structure, the spindle that supports the raw wood receives the cutting force of the blade, and
Even if a force is applied to the spindle that causes it to deflect in a direction substantially opposite to the area where the cutter contacts the raw wood, the spindle will be pressed and supported against the deflection by the supporting member provided in contact with a predetermined area on the circumferential surface of the spindle. Therefore, the amount of deflection is small, and since there is no support member on the blade side, the blade can approach the spindle side and cut the log.

。On the other hand, a drive shaft 13 rotated by a motor (not shown) is provided, a gear 15 also equipped with a sliding key 14 is disposed at a location corresponding to the gear 9, and a cylinder (not shown) is disposed on the outer periphery of the gear 15. A U-shaped movable member 16 that is movable in the direction of the arrow is provided opposite to each other, and a position where the gear 15 meshes with the gear 9 on the drive shaft 13 and a position away from the gear 9 due to the movement of the movable member 16 are provided. A gear 17 that meshes with the gear 10 is fixed to the drive shaft 13 so that the gear 17 can freely reciprocate between the drive shaft and the position indicated by the dashed line in FIG.
また、ガイド部材６を備えた筒状体５を希望する状態に
固定させるために歯車９の回転を阻止するべく歯車９に
相対して前後動自在のストッパー１８を配置する。Further, in order to fix the cylindrical body 5 provided with the guide member 6 in a desired state, a stopper 18 that is movable back and forth is arranged relative to the gear 9 to prevent rotation of the gear 9.
尚、スピンドル４又は筒状体５の軸方向への前進後退の

ッパー１８は歯車９から離しておく。In the apparatus configured as described above, first the spindle 4
and the cylindrical body 5 are moved together to support the raw wood W with the spindle 4. On the other hand, the cylindrical body 5 is positioned so that the guide member 6 is slightly away from the end surface of the raw wood W, and the gear 15 is moved by the moving member 1.
6 is moved and adjusted to mesh with the gear 9, and the stopper 18 is kept separated from the gear 9.
この状態で駆動軸１３を回転させると、スピンドル４及

車９に当接させた状態とする。When the drive shaft 13 is rotated in this state, the spindle 4 and the cylindrical body 5 are rotated together, the log W is rotated, and the tool rest 1 is moved toward the log W, so that the cutter 2 can cut the log. W is cut. When the cutting progresses and the diameter of the remaining raw wood W becomes slightly larger than the rotating diameter of the guide member 6, the rotation of the drive shaft 13 is stopped, and then the movable member 16 is moved to move the gear 15 onto the drive shaft 13. The guide member 6 is moved away from the position where it does not mesh with the gear 9 (the position shown by the dashed line in FIG. 1), and then the cylindrical body 5 is manually rotated.
After positioning the stopper 18 so that it is on the opposite side of the spindle 4 from the cutter 2 (see FIG. 2), the stopper 18 is advanced so that it comes into contact with the gear 9.

木Ｗを回転させて切削が行なわれ、一方歯車９は歯車１
５とは噛み合っておらずしかもストッパー１８が当接さ

た位置に停止することとなるのである。When the drive shaft 13 is rotated again in this state, since the gear 10 is meshed with the gear 17, the spindle 4 rotates and the raw wood W is rotated to perform cutting, while the gear 9 is rotated by the gear 1
Since the guide member 6 is not engaged with the guide member 5 and is in contact with the stopper 18, the guide member 6 is stopped at the set position.
それ故スピンドル４は、刃物２の切削力等によって刃物
２と反対側に曲げられようとしても、それに抗して支持
部材としてのガイド部材６によって押圧支持され、スピ
ンドル↓のたわみ量は小となり切削された単板の厚さも
ほとんど均一となって十分に使用可能となるのである。Therefore, even if the spindle 4 is bent toward the opposite side of the cutter 2 due to the cutting force of the cutter 2, etc., it will be supported by the guide member 6 as a support member, and the amount of deflection of the spindle ↓ will be small. The thickness of the resulting veneer becomes almost uniform, making it fully usable.

場合でもそれぞれに対応できスピンドル１９のたわみを
より小さいものとすることができる。Furthermore, since there is no support member on the blade 2 side of the spindle 4 that prevents the blade 2 from advancing, the blade 2 can approach the spindle 4 very close to cut the raw wood W, making it possible to remove the core. The diameter is reduced to approximately the same extent as the spindle 4, and walking performance is improved. Further, since the cylindrical body 5 provided with the guide member 6 is configured to be able to move forward and backward in the axial direction as described above, the guide member 6 allows the spindle 19
can be pressed and supported at a location close to the end face of the raw wood W against its deflection, so even if the length of the raw wood W to be cut differs, it can be handled individually and the deflection of the spindle 19 can be made smaller. can.

い。In addition, in this embodiment, the guide member 6 as a support member
When the raw wood W has a large diameter, the amount of deflection during cutting is relatively small, so it was rotated together with the spindle 4, but the guide member 6 was stopped at the above position from the beginning, although the rotational resistance against the spindle 4 increased slightly. It is also possible to fix the spindle 4 so that the deflection of the spindle 4 is small.Also, the guide member 6 was manually positioned on the opposite side of the cutter 2. A piece of iron is projected and fixed on the side where the guide member 6 of No. 5 is located, and a proximity switch is provided on the side opposite to the cutter 2 on the running path of the piece of iron,
After it becomes necessary to position the guide member 6 on the opposite side, the clutch brake is actuated to stop the drive shaft 13 by the signal from the proximity switch detecting the iron piece, and then the moving member 16 is moved by the signal. The gear 15 may be moved away from the gear 9 to a position where it does not mesh with the gear 9, and the stopper 18 may be further advanced to come into contact with the gear 9.
次に本発明の第２の実施例を説明する。Next, a second embodiment of the present invention will be described.
ベニヤレースとしては特開昭５８−１１４９０１号公報

切削し単板を得るものである。In this veneer lace B, a hole with a diameter equal to the diameter of a spindle is formed on the end face of the raw wood using a drill, the spindle is inserted into the six holes 7, the raw wood is rotated, and the veneer is cut with a blade to obtain a veneer.
このような構成であれば、原木は中心部に補強材を備え
た状態となり原木自身の切削時のたわみは大幅に減少さ
れるのである。With such a structure, the log has a reinforcing material in its center, and the deflection of the log itself during cutting is greatly reduced.

The spindles 19 are moved forward and inserted into the holes 20 formed on both end faces of the log W while being kept away from the log W, thereby supporting the log W. Next, the support body 21 is moved in a direction parallel to the spindle 19, and the roll 22 is moved by the spindle 19 to a location corresponding to the outer peripheral surface of the raw wood W near the end surface of the raw wood W in the outside part of the raw wood W. 21 is brought close to the spindle 19, and the roll 22 is brought into pressure contact with the circumferential surface of the spindle 19.
このように配置した後、スピンドル１９によって原木Ｗ
