Description
この発明は、用材の挽割面の段差をなくして製材工程の合理化を図ることができる二軸丸鋸盤における製材方法に関する。 The present invention relates to a lumber sawing method using a two-shaft circular saw machine that can streamline the lumbering process by eliminating steps on the sawn surface of lumber.
高性能な二軸丸鋸盤が開発され、広く実用されている（特許文献１、２）。 A high-performance two-axis circular saw has been developed and is widely used (Patent Documents 1 and 2).
二軸丸鋸盤は、用材の搬送面の上下にそれぞれ第１鋸刃、第２鋸刃を配設し、第１鋸刃は、第２鋸刃に対して前後方向、上下方向に平行移動可能である。第１鋸刃は、第２鋸刃と同一垂直面内にセットして第２鋸刃に対して重なり代を有する垂直配置と、下側の有効半径部分が第２鋸刃の上側の有効半径部分と水平方向に重なるとともに、用材の搬送面に対して重なり代を有する並列配置とをとることができる。すなわち、第１鋸刃、第２鋸刃は、垂直配置をとることにより、上下方向から用材の同一垂直面を切断し、第１鋸刃、第２鋸刃の各有効半径の２倍近くの厚さの用材を一挙に挽き割ることができ、並列配置をとることにより、それぞれの各有効半径以下の厚さの用材の２箇所を同時に切断して挽き割ることができる。なお、第１鋸刃、第２鋸刃は、同径、同刃厚の同一仕様のチップソーまたは普通の丸鋸刃を使用する。 A two-shaft circular saw machine has a first saw blade and a second saw blade arranged above and below the material conveyance surface, respectively, and the first saw blade is movable parallel to the second saw blade in the front-rear direction and the vertical direction. It is. The first saw blade is set in the same vertical plane as the second saw blade and has a vertical arrangement with an overlap margin with respect to the second saw blade, and the lower effective radius portion is the upper effective radius of the second saw blade. It is possible to take a parallel arrangement in which the parts overlap in the horizontal direction and have an overlap margin with respect to the transport surface of the materials. In other words, the first saw blade and the second saw blade cut the same vertical surface of the material from above and below by taking a vertical arrangement, and cut the same vertical surface of the material from the top and bottom directions, and cut the same vertical surface of the material from the top and bottom directions, and cut the same vertical surface of the material from the top and bottom directions. By arranging the machines in parallel, it is possible to simultaneously cut and saw two parts of the material whose thickness is less than each effective radius. Note that, as the first saw blade and the second saw blade, a tipped saw blade or an ordinary circular saw blade having the same diameter and the same blade thickness and the same specification is used.
かかる従来技術によるときは、第１鋸刃、第２鋸刃を垂直配置にして用材を挽き割ると、用材の挽割面に対し、第１鋸刃または第２鋸刃の刃先相当の位置に微小な段差を生じることがあるという問題があった。なお、このような挽割面の段差は、必要に応じて、製材後の仕上げ用の切削工程によって除去することができる。 According to such conventional technology, when the first saw blade and the second saw blade are arranged vertically and the lumber is sawed, the cutting edge of the first saw blade or the second saw blade is located at a position corresponding to the cutting edge of the saw blade with respect to the sawed surface of the lumber. There has been a problem in that minute differences in level may occur. In addition, such a level difference in the sawn surface can be removed by a finishing cutting process after sawing the lumber, if necessary.
そこで、この発明の目的は、かかる従来技術の問題に鑑み、第２鋸刃の有効半径を十分大きくするとともに刃厚を適切に設定することによって、用材の挽割面に段差を生じることがなく、仕上げ用の切削工程を不要にすることができる二軸丸鋸盤における製材方法を提供することにある。 Therefore, in view of the problems of the prior art, an object of the present invention is to make the effective radius of the second saw blade sufficiently large and set the blade thickness appropriately, thereby eliminating the occurrence of a step on the sawn surface of the sawn material. An object of the present invention is to provide a lumber sawing method using a two-axis circular saw machine that can eliminate the need for a finishing cutting process.
かかる目的を達成するためのこの発明の構成は、上流側の第１鋸刃が下流側の第２鋸刃に対して前後方向、上下方向に平行移動し、上下方向から用材の同一垂直面を切断する垂直配置、用材の２箇所を同時に切断する並列配置が可能な二軸丸鋸盤における製材方法であって、余裕寸法δ1 、δ2 として、第１鋸刃は、搬送面上の用材の厚さＤの半分を超える範囲を挽割可能な有効半径Ｒ1 ＝Ｄ／２＋δ1 ＞Ｄ／２のチップソーにし、第２鋸刃は、搬送面上の用材の厚さＤの全部を挽割可能な有効半径Ｒ2 ＝Ｄ＋δ2 ＞Ｄのチップソーにするとともに刃厚を第１鋸刃の刃厚より大きくし、第１鋸刃を第２鋸刃と同一垂直面内にセットして第１鋸刃、第２鋸刃により用材を挽き割る一方、第２鋸刃は、第１鋸刃と同径、同刃厚の同一仕様に変更可能であることをその要旨とする。 In order to achieve this object, the present invention has a configuration in which the first saw blade on the upstream side moves parallel to the second saw blade on the downstream side in the longitudinal direction and the vertical direction, and the same vertical plane of the material is cut from the vertical direction. A lumber sawing method using a two-axis circular saw machine that allows for vertical arrangement for cutting and parallel arrangement for simultaneously cutting two parts of the material, with the margin dimensions δ1 and δ2, the first saw blade is cut by the thickness of the material on the conveying surface. The chip saw has an effective radius R1 = D/2 + δ1 > D/2 that can saw more than half of D, and the second saw blade has an effective radius that can saw the entire thickness D of the material on the conveying surface. R2 = D + δ2 >D is used as a chip saw, and the blade thickness is made larger than the blade thickness of the first saw blade, and the first saw blade is set in the same vertical plane as the second saw blade, and the first saw blade and the second saw blade are The gist is that while the blade cuts the material, the second saw blade can be changed to have the same specifications as the first saw blade, with the same diameter and the same blade thickness.
なお、第２鋸刃は、有効半径Ｒ2 相当を搬送面上に突出させて配置することができる。 Incidentally, the second saw blade can be arranged so that an area corresponding to the effective radius R2 protrudes above the conveying surface.
かかる発明の構成によるときは、第１鋸刃、第２鋸刃は、それぞれ搬送面上の用材の同一垂直面を切断して用材を一挙に挽き割ることができる。また、このとき、下流側の第２鋸刃は、第１鋸刃より刃厚が大きく、搬送面上の用材の厚さの全部を挽割可能であるため、挽割面の全面を平滑に仕上げ、挽割面に段差を生じるおそれがない。なお、第２鋸刃は、第１鋸刃と同一垂直面を挽き割るため、第１鋸刃を使用しない場合に比して、本体厚を薄くして全体剛性を小さくすることができ、耐久性を向上させることができる。 According to the configuration of the invention, the first saw blade and the second saw blade can respectively cut the same vertical plane of the material on the conveying surface and split the material at once. In addition, at this time, the second saw blade on the downstream side has a larger blade thickness than the first saw blade and is capable of sawing the entire thickness of the material on the conveying surface, so the entire surface of the sawing surface can be smoothed. There is no risk of creating a level difference on the finished or sawn surface. In addition, since the second saw blade cuts the same vertical plane as the first saw blade, the main body thickness can be made thinner and the overall rigidity can be reduced compared to when the first saw blade is not used, which improves durability. can improve sex.
第２鋸刃の刃厚Ｔ2 は、第１鋸刃の刃厚Ｔ1 に対し、（Ｔ2 －Ｔ1 ）／２＝０．２～０．３mmとすることにより、用材の歩留りを過度に損うことがなく、用材の挽割面の全面を良好に仕上げることができる。すなわち、（Ｔ2 －Ｔ1 ）／２が０．２mm未満では、第２鋸刃による挽割面の仕上げが不十分になる可能性があり、０．３mm超では、歩留りの低下が過大になるおそれがある。 By setting the blade thickness T2 of the second saw blade to (T2 - T1)/2 = 0.2 to 0.3 mm with respect to the blade thickness T1 of the first saw blade, the yield of material will be excessively impaired. There is no cracking, and the entire sawn surface of the lumber can be finished well. In other words, if (T2 - T1)/2 is less than 0.2 mm, there is a possibility that the finishing of the sawn surface by the second saw blade will be insufficient, and if it exceeds 0.3 mm, there is a risk that the yield will decrease excessively. There is.
第１鋸刃は、搬送面上の用材の厚さの半分以上、より好ましくは、半分を多少超える範囲を挽割可能な有効半径に設定することにより、同径、同刃厚の同一仕様の第２鋸刃と組み合わせて、従来の二軸丸鋸盤における垂直配置の場合と同様の挽割動作を円滑に実現することができる。 By setting the effective radius of the first saw blade to be at least half of the thickness of the material on the conveying surface, and more preferably slightly over half, the first saw blade can be used to cut materials with the same diameter and blade thickness. In combination with the second saw blade, it is possible to smoothly realize the sawing and splitting operation similar to that in the vertical arrangement of a conventional two-axis circular saw.
以下、図面を以って発明の実施の形態を説明する。 Embodiments of the invention will be described below with reference to the drawings.
二軸丸鋸盤における製材方法は、上流側の第１鋸刃Ｓ1 、下流側の第２鋸刃Ｓ2 を備える二軸丸鋸盤において実施する（図１、図２）。なお、第１鋸刃Ｓ1 は、第２鋸刃Ｓ2 に対し、前後方向（図１の紙面に垂直方向）、上下方向に平行移動可能である。ただし、図２（Ａ）は、図１のＸ矢視相当模式図、図２（Ｂ）は、同図（Ａ）の要部模式拡大図である。 The sawing method using a two-shaft circular saw machine is carried out on a two-shaft circular saw machine equipped with a first saw blade S1 on the upstream side and a second saw blade S2 on the downstream side (FIGS. 1 and 2). Note that the first saw blade S1 is movable parallel to the second saw blade S2 in the front-rear direction (perpendicular to the plane of the paper in FIG. 1) and in the up-down direction. However, FIG. 2(A) is a schematic view corresponding to the X arrow view of FIG. 1, and FIG. 2(B) is a schematic enlarged view of the main part of FIG. 2(A).
第１鋸刃Ｓ1 、第２鋸刃Ｓ2 は、用材Ｗの搬送面Ｗa の上下に配設する水平の駆動軸Ｓ1a、Ｓ2aに対し、それぞれフランジＳ1b、Ｓ1b、Ｓ2b、Ｓ2bを介して着脱可能に装着されている。なお、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 は、それぞれ外周に刃先用のチップＳ1c、Ｓ1c…、Ｓ2c、Ｓ2c…を設けるチップソーである。第１鋸刃Ｓ1 の刃厚Ｔ1 に対し、第２鋸刃Ｓ2 の刃厚Ｔ2 ＞Ｔ1 は、（Ｔ2 －Ｔ1 ）／２＝０．２～０．３mmに設定されている。また、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 の有効半径Ｒ1 、Ｒ2 は、それぞれ搬送面Ｗa 上の用材Ｗの厚さＤの半分以上、全部を用材Ｗの上方向、下方向から切断して挽割可能に設定されている。すなわち、図１において、第１鋸刃Ｓ1 の有効半径Ｒ1 ＝Ｄ／２＋δ1 ＞Ｄ／２であり、第２鋸刃Ｓ2 の有効半径Ｒ2 ＝Ｄ＋δ2 ＞Ｄである。ただし、余裕寸法δ1 、δ2 は、それぞれ数mm以上数１０mm以下程度に設定するとよい。 The first saw blade S1 and the second saw blade S2 are removably attached to horizontal drive shafts S1a and S2a disposed above and below the conveyance surface Wa of material W via flanges S1b, S1b, S2b, and S2b, respectively. It is installed. The first saw blade S1 and the second saw blade S2 are tipped saws having cutting edge chips S1c, S1c..., S2c, S2c... on their outer peripheries, respectively. With respect to the blade thickness T1 of the first saw blade S1, the blade thickness T2 of the second saw blade S2 >T1 is set to (T2 - T1)/2=0.2 to 0.3 mm. Moreover, the effective radii R1 and R2 of the first saw blade S1 and the second saw blade S2 are more than half of the thickness D of the material W on the conveying surface Wa, and cut the entire material W from above and below, respectively. It is set up so that it can be cut. That is, in FIG. 1, the effective radius of the first saw blade S1 is R1 =D/2+δ1>D/2, and the effective radius of the second saw blade S2 is R2=D+δ2>D. However, the margin dimensions δ1 and δ2 are preferably set to a value of several mm or more and several tens of mm or less, respectively.
第１鋸刃Ｓ1 を第２鋸刃Ｓ2 と同一垂直面内にセットし、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 に向けて搬送面Ｗa 上に用材Ｗを送材すると（図１の矢印Ｗ1 方向）、上流側の第１鋸刃Ｓ1 は、用材Ｗの上半部を上方向から切断し、下流側の第２鋸刃Ｓ2 は、用材Ｗの残りの下半部を切断して、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 により用材Ｗを挽き割ることができる。また、第２鋸刃Ｓ2 は、同時に挽割面の全面を切削して仕上げることにより、挽割面に段差が生じることを防止する。 When the first saw blade S1 is set in the same vertical plane as the second saw blade S2, and the material W is conveyed onto the conveying surface Wa toward the first saw blade S1 and the second saw blade S2 (arrow in FIG. W1 direction), the first saw blade S1 on the upstream side cuts the upper half of the material W from above, and the second saw blade S2 on the downstream side cuts the remaining lower half of the material W. The material W can be sawed by the first saw blade S1 and the second saw blade S2. Further, the second saw blade S2 simultaneously cuts and finishes the entire surface of the sawn surface, thereby preventing the formation of a step on the sawn surface.
ただし、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 は、それぞれ図１の矢印Ｙ1 、Ｙ2 方向に回転駆動するとともに、それぞれ下側、上側の有効半径部分のほぼ全部を用材Ｗの挽割動作に使用する。また、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 の垂直方向、水平方向の軸間距離ａ、ｂは、それぞれ第１鋸刃Ｓ1 、第２鋸刃Ｓ2 が干渉することなく動作し得る最小距離に設定すればよい。なお、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 は、チップソーでない普通の丸鋸刃であってもよい。 However, the first saw blade S1 and the second saw blade S2 are rotatably driven in the directions of arrows Y1 and Y2 in FIG. use. Further, the distances a and b between the vertical and horizontal axes of the first saw blade S1 and the second saw blade S2 are the minimum distances in which the first saw blade S1 and the second saw blade S2 can operate without interference, respectively. You can set it to . Note that the first saw blade S1 and the second saw blade S2 may be ordinary circular saw blades other than a chip saw.
一方、第２鋸刃Ｓ2 を第１鋸刃Ｓ1 と同一仕様に変更すると、従来の二軸丸鋸盤におけると同様にして、第１鋸刃Ｓ1 、第２鋸刃Ｓ2 を垂直配置、並列配置して用材Ｗの１箇所または２箇所を挽き割ることができる。 On the other hand, when the second saw blade S2 is changed to the same specifications as the first saw blade S1, the first saw blade S1 and the second saw blade S2 are arranged vertically and in parallel, similar to the conventional two-axis circular saw machine. The lumber W can be sawed at one or two places.
この発明は、有効半径が十分大きく、刃厚が大きな第２鋸刃を使用することにより、挽割面に段差を生じることがなく、たとえば紙材、布材などのシート材を扱う使い捨てのパレット材などのように、表面の段差を嫌う部材を効率よく製材して製作する用途に対し、殊に好適に適用することができる。 By using a second saw blade with a sufficiently large effective radius and a large blade thickness, this invention eliminates the generation of steps on the sawing surface, making it possible to use disposable pallets for handling sheet materials such as paper and cloth. It can be particularly suitably applied to the use of efficiently sawing and manufacturing members such as lumber that dislike surface level differences.
