Abstract
Description
本発明は、材料を鋸車に張架された帯鋸により切断等の加工を行うバンドソーに関する。 The present invention relates to a band saw that performs processing such as cutting with a band saw stretched on a saw wheel.
作業者によるトリガの操作に応じてモータを回転させて駆動鋸車を駆動し、駆動鋸車と従動鋸車との間に張架される環状の帯鋸を回転させることにより鉄パイプ等の被切断材を切断する携帯可能なバンドソーが従来より存在する。 According to the trigger operation by the operator, the drive saw wheel is driven by rotating the motor, and an annular band saw stretched between the drive saw wheel and the driven saw wheel is rotated to cut an iron pipe or the like. Conventionally, there are portable band saws for cutting materials.
例えば、特許文献１には、駆動鋸車上方にモータを配置し、従動鋸車上方に駆動源となる電池パックを配置し、従動鋸車付近にトリガスイッチを持つメインハンドル、駆動鋸車付近にサブハンドルを備えた構造のバンドソーが開示されている。 For example, in Patent Document 1, a motor is disposed above the drive saw wheel, a battery pack serving as a drive source is disposed above the driven saw wheel, a main handle having a trigger switch near the driven saw wheel, and near the drive saw wheel. A band saw with a sub-handle is disclosed.
特許文献１に示す技術は、全体の重心バランスを向上させる目的で、重量物であるモータと電池パックを、離間して配置した構成をしているが、メインハンドルが本体の従動鋸車付近に配置された構成であるため、メインハンドルのみを把持して作業する際には、操作性が悪いものであった。 また、駆動鋸車と従動鋸車との間の切断領域において、帯鋸が鋸車に対して傾斜するように、切断領域の前後に配置されたガイド部材によりガイドされるが、このようなバンドソーの構造上、メインハンドルを帯鋸による切断面上に配置することはできず、メインハンドルと切断面とは平行に配置されている。このため、操作者は切断面を把握することが難しく、切断面に沿ってバンドソーを移動させて、例えば被削材に垂直な切断を行うなどの精度の高い作業を行うことが難しいものであった。
本発明は上記背景に鑑みてなされたもので、その目的は、操作性が良く、且つ高精度な切断作業が可能なバンドソーを提供することである。
The technique shown in Patent Document 1 has a configuration in which a heavy motor and a battery pack are arranged apart from each other for the purpose of improving the balance of the center of gravity of the whole, but the main handle is located near the driven saw wheel of the main body. Because of the arrangement, the operability is poor when working with only the main handle. Further, in the cutting region between the drive saw wheel and the driven saw wheel, the band saw is guided by guide members arranged before and after the cutting region so as to be inclined with respect to the saw wheel. Due to the structure, the main handle cannot be arranged on the cut surface by the band saw, and the main handle and the cut surface are arranged in parallel. For this reason, it is difficult for the operator to grasp the cut surface, and it is difficult to move the band saw along the cut surface and perform highly accurate work such as cutting perpendicular to the work material. It was.
The present invention has been made in view of the above background, and an object of the present invention is to provide a band saw having good operability and capable of cutting work with high accuracy.
上記目的は、

前記ハンドルは、前記切断領域における前記帯鋸の走行方向に延びると共に、前記切断領域に対して前記接続部上方に位置するよう前記接続部と一体的に構成され、
前記接続部に、前記切断領域よりも前記ハンドル側において、前記切断領域に位置する前記帯鋸の側面を含む仮想面に向かって突出する切断位置ガイド部を設けることにより達成することができる。
The above purpose is
A driving saw wheel, a driven saw wheel, a motor for rotating the driving saw wheel, a driving saw wheel base and a driven saw wheel base for rotatably supporting the driving saw wheel and the driven saw wheel, and the driving A band saw stretched between the saw wheel and the outer periphery of the driven saw wheel, a connection portion connecting the drive side saw wheel base and the driven side saw wheel base, and a handle having a trigger for controlling the drive of the motor; In a band saw for cutting work material by the band saw in a cutting region between the drive side saw wheel base and the driven side saw wheel base,
The handle extends in the traveling direction of the band saw in the cutting region, and is configured integrally with the connecting portion so as to be positioned above the connecting portion with respect to the cutting region,
This can be achieved by providing the connection portion with a cutting position guide portion that protrudes toward a virtual surface including the side surface of the band saw located in the cutting region on the handle side of the cutting region.
本発明によれば、操作性が良く、切断領域における帯鋸の側面、すなわち切断面を把握しやすく、高精度な切断作業を行うことができるバンドソーを提供することができる。 According to the present invention, it is possible to provide a band saw that has good operability, can easily grasp the side surface of the band saw in the cutting region, that is, the cutting surface, and can perform a highly accurate cutting operation.
図１は本発明の実施例に係るバンドソー１の正面図である。バンドソー１は、作業者が操作するトリガ４を有するハンドル３と、不図示のモータを収容するモータハウジング８と、モータに電力を供給する電池パック２と、モータによって回転する駆動鋸車１３を収容する駆動鋸ベース１０と、駆動鋸車１３と共に帯鋸１２を張架される従動鋸車１５及び従動鋸車１５を収容する従動鋸ベース１１と、帯鋸１２の一部を収容し、駆動鋸ベース１０と従動鋸ベース１１を接続する接続部６と、から構成される。また、接続部６はハンドル３と一体となっている
駆動鋸ベース１０と従動鋸ベース１１との間には帯鋸１２の一部が露出する切断領域１９が形成される。接続部６はハンドル３と切断領域１９との間に配置され、接続部６のハンドル３側には切断位置ガイド部１８が設けられている。切断領域１９の駆動鋸ベース１０側には被切断材２１の移動を規制するガイドプレート９が設けられている。接続部６の電池パック２側には、切断領域１９に光を照射するライト２２が設けられており、ライト２２はＬＥＤより構成される。なお、以降の説明においては、図１の紙面手前を前方向、紙面上下方向を上下方向と定義する。
FIG. 1 is a front view of a band saw 1 according to an embodiment of the present invention. The band saw 1 houses a handle 3 having a trigger 4 operated by an operator, a motor housing 8 that houses a motor (not shown), a battery pack 2 that supplies electric power to the motor, and a driving saw wheel 13 that is rotated by the motor. Drive saw base 10, a driven saw wheel 15 on which a band saw 12 is stretched together with a drive saw wheel 13, a driven saw base 11 that houses the driven saw wheel 15, a part of the band saw 12, and a drive saw base 10 And a connecting portion 6 for connecting the driven saw base 11 to each other. The connecting portion 6 is integrated with the handle 3. A cutting region 19 where a part of the band saw 12 is exposed is formed between the drive saw base 10 and the driven saw base 11. The connecting portion 6 is disposed between the handle 3 and the cutting area 19, and a cutting position guide portion 18 is provided on the handle 3 side of the connecting portion 6. A guide plate 9 that restricts the movement of the material to be cut 21 is provided on the side of the drive saw base 10 in the cutting region 19. A light 22 for irradiating light to the cutting area 19 is provided on the battery pack 2 side of the connecting portion 6, and the light 22 is constituted by an LED. In the following description, the front side of the sheet of FIG. 1 is defined as the forward direction, and the vertical direction of the sheet is defined as the vertical direction.
図２は、バンドソー１を上から見た平面図である。切断領域１９における帯鋸１２の側面は上下方向に平行であるため、図２においては帯鋸１２の上端部のみ見えている状態である。図２に示されるように、切断位置ガイド部１８は接続部６から前方向に向かって突出している。換言すれば、帯鋸１２の側面を通る平面を仮想面としたとき、切断位置ガイド部１８は仮想面に直交する方向に突設されている。また切断位置ガイド部１８は、帯鋸１２と平行に延びるガイド面１８ａと、ガイド面１８ａから接続部６に向かって傾斜する傾斜面１８ｂを有する。 FIG. 2 is a plan view of the band saw 1 as viewed from above. Since the side surface of the band saw 12 in the cutting region 19 is parallel to the vertical direction, only the upper end portion of the band saw 12 is visible in FIG. As shown in FIG. 2, the cutting position guide portion 18 protrudes forward from the connection portion 6. In other words, when the plane passing through the side surface of the band saw 12 is taken as a virtual surface, the cutting position guide portion 18 protrudes in a direction perpendicular to the virtual surface. The cutting position guide portion 18 has a guide surface 18 a extending in parallel with the band saw 12 and an inclined surface 18 b inclined from the guide surface 18 a toward the connecting portion 6.
ガイド面１８ａは切断領域１９における帯鋸１２の側面と平行であり、帯鋸１２はガイド面１８ａからわずかながら前側に位置しているため、図２に様にバンドソー１を上から見たときにはガイド面１８ａと帯鋸１２の位置はほぼ一致している。また、ガイド面１８ａは切断領域１９の左右方向寸法のほぼ半分の長さとなっている。また、モータハウジング８は駆動鋸ベース１０から前方向かつ上方向に延びるように設けられており、従動鋸ベース１１からはサブハンドル３０が前方向に延びるように設けられている。これによって、バンドソー１の後方には突出する部分がない構成となる。 Since the guide surface 18a is parallel to the side surface of the band saw 12 in the cutting region 19, and the band saw 12 is located slightly forward from the guide surface 18a, the guide surface 18a is viewed when the band saw 1 is viewed from above as shown in FIG. The positions of the band saw 12 are substantially the same. Further, the guide surface 18a has a length approximately half of the horizontal dimension of the cutting region 19. Further, the motor housing 8 is provided so as to extend forward and upward from the drive saw base 10, and the sub handle 30 is provided so as to extend forward from the driven saw base 11. As a result, there is no protruding portion behind the band saw 1.
図３、４に示すように、ハンドル３及び接続部６は２つのハウジング片３ａ、３ｂをネジ５にて固定することで一体となっており、切断位置ガイド部１８は一方のハウジング片３ａに一体的に構成されている。さらに、一体となったハンドル３は図１に示すようにネジ７で駆動鋸ベース１０及び従動鋸ベース１１に固定される。また、ハンドル３を一体にすると同時にハンドル３の左方向には電池装着部２ａが形成される。電池装着部２ａは不図示の上下方向に延びるレール部を有し、電池パック２はレール部に摺動させるように装着される。故に、左右方向に延びるハンドル３と直交する方向に摺動させることで、電池パック２は着脱される。 As shown in FIGS. 3 and 4, the handle 3 and the connecting portion 6 are integrated by fixing two housing pieces 3 a and 3 b with screws 5, and the cutting position guide portion 18 is attached to one housing piece 3 a. It is constructed integrally. Further, the integrated handle 3 is fixed to the drive saw base 10 and the driven saw base 11 with screws 7 as shown in FIG. Further, at the same time that the handle 3 is integrated, a battery mounting portion 2a is formed on the left side of the handle 3. The battery mounting portion 2a has a rail portion that extends in the vertical direction (not shown), and the battery pack 2 is mounted so as to slide on the rail portion. Therefore, the battery pack 2 is attached and detached by sliding in the direction orthogonal to the handle 3 extending in the left-right direction.
モータの一端部に不図示の減速機構部が配設され、減速機構部の先端部（出力側）には円形の滑車である駆動鋸車１３が取付ねじ１４により固定されており、従動鋸車１５は従動鋸ベース１１において取り付けネジ１４により回転可能に保持されている。被切断材２１を切断するための帯鋸１２は、切断領域１９における側面を上下方向に平行とするために、駆動鋸ベース１０に対して傾斜した状態で、駆動鋸ベース１０に取付けられたガイドローラＡ１６に挿通される。前記帯鋸１２は従動鋸ベース１１においても同様に傾斜された状態で取付けられたガイドローラＢ１７を挿通し、駆動鋸車１３と従動鋸車１５に張架される。ガイドローラＡ１６及びガイドローラＢ１７は切断領域１９のそれぞれ左右近傍に配置されるため、切断領域１９における帯鋸１２とは、ガイドローラＡ１６とガイドローラＢ１７との間にある帯鋸１２とほぼ同義である。 A speed reduction mechanism (not shown) is disposed at one end of the motor, and a driving saw wheel 13 which is a circular pulley is fixed to a tip end (output side) of the speed reduction mechanism by a mounting screw 14. 15 is rotatably held by a mounting screw 14 in the driven saw base 11. The band saw 12 for cutting the workpiece 21 is a guide roller attached to the drive saw base 10 in an inclined state with respect to the drive saw base 10 so that the side surface in the cutting region 19 is parallel to the vertical direction. A16 is inserted. The band saw 12 is also stretched around the drive saw wheel 13 and the driven saw wheel 15 through a guide roller B17 attached in the same manner in the driven saw base 11 in an inclined state. Since the guide roller A16 and the guide roller B17 are arranged in the vicinity of the left and right sides of the cutting region 19, the band saw 12 in the cutting region 19 is substantially synonymous with the band saw 12 between the guide roller A16 and the guide roller B17.
次に、バンドソー１による作業を説明する。バンドソー１によって切断作業を行う場合は、ハンドル３を把持して、バンドソー１を被切断材２１の上側に位置させ、切断領域１９における帯鋸１２の面方向が切断予定面と一致するように位置づける。ここで言う切断領域１９とは、被切断材２１の切断中に被切断材２１が位置し得る領域を言い、本実施例では駆動鋸ベース１０と従動鋸ベース１１との間の空間である。そして作業者はトリガ４を操作することによりモータを回転駆動させ、減速機構部を介して駆動鋸車１３を回転させる。駆動鋸車１３が回転すると、回転力が帯鋸１２に伝わり、更に帯鋸１２の回転力が従動鋸車１５に伝達することで、駆動鋸車１３と帯鋸１２と従動鋸車１５とが回転駆動する。 Next, the work by the band saw 1 will be described. When performing the cutting operation with the band saw 1, the handle 3 is grasped, the band saw 1 is positioned above the workpiece 21, and the surface direction of the band saw 12 in the cutting region 19 is positioned so as to coincide with the planned cutting surface. The cutting area 19 here refers to an area where the workpiece 21 can be positioned during the cutting of the workpiece 21, and in this embodiment is a space between the drive saw base 10 and the driven saw base 11. Then, the operator operates the trigger 4 to rotationally drive the motor, and rotates the drive saw wheel 13 via the speed reduction mechanism. When the drive saw wheel 13 rotates, the rotational force is transmitted to the band saw 12, and further the rotational force of the band saw 12 is transmitted to the driven saw wheel 15, whereby the drive saw wheel 13, the band saw 12, and the driven saw wheel 15 are rotationally driven. .
帯鋸１２は切断領域１９において、図２における走行方向２０の方向に走行するように回転し、走行方向２０はガイド面１８ａの延在方向と同一である。換言すれば、ガイド面１８ａは、帯鋸１２の走行方向２０と同一方向に延在する。帯鋸１２を回転させた状態にてバンドソー１を被切断材２１に向けて下方に移動させる（図１）。図１における被切断材２１は前後方向に延びているが、この際、精度良く被切断材２１を切断するため、切断領域１９における帯鋸１２の側面が鉄パイプなどの被切断材２１と正しい角度（鉄パイプならその長手方向の垂直方向）に位置させながら、バンドソー１を下に移動させることが重要である。 The band saw 12 rotates so as to travel in the traveling direction 20 in FIG. 2 in the cutting region 19, and the traveling direction 20 is the same as the extending direction of the guide surface 18a. In other words, the guide surface 18 a extends in the same direction as the traveling direction 20 of the band saw 12. With the band saw 12 rotated, the band saw 1 is moved downward toward the workpiece 21 (FIG. 1). The material 21 to be cut in FIG. 1 extends in the front-rear direction. At this time, in order to cut the material 21 with high accuracy, the side surface of the band saw 12 in the cutting region 19 is at the correct angle with the material 21 to be cut such as an iron pipe. It is important to move the band saw 1 downward while being positioned in the vertical direction of the longitudinal direction of an iron pipe.
バンドソー１を下に移動させながら切断作業を行う場合、作業者は上からバンドソー１を目視しながら切断作業を行っていくことになるが、この時、図２の様に切断予定面とガイド面１８ａと帯鋸１２をほぼ重ねるようにすることで、被切断材２１の切断予定面と切断領域１９における帯鋸１２の側面がなす角度を可能な限り小さくできる。換言すれば、切断予定面と、切断領域１９における帯鋸１２の側面とを同一平面（仮想面）上に位置させることができる。そして、その状態のままバンドソー１を下に移動させていけば、切断予定面に沿った切断を行うことができる。 When performing the cutting operation while moving the band saw 1 downward, the operator performs the cutting operation while visually observing the band saw 1 from above. At this time, as shown in FIG. By making the 18a and the band saw 12 substantially overlap, the angle formed between the planned cutting surface of the workpiece 21 and the side surface of the band saw 12 in the cutting region 19 can be made as small as possible. In other words, the planned cutting surface and the side surface of the band saw 12 in the cutting region 19 can be positioned on the same plane (virtual surface). And if the band saw 1 is moved down in that state, cutting along the planned cutting surface can be performed.
また、図２に示すように、切断領域１９における被切断材２１の一部が傾斜部１８ｂの形成により目視できるようになっている。 Further, as shown in FIG. 2, a part of the material 21 to be cut in the cutting region 19 can be visually observed by forming the inclined portion 18b.
また、暗所での作業など、作業者は作業状態にあわせて不図示のライトスイッチを操作することでライト２２をＯＮして切断領域を明るく照らして作業を行う。このとき、図１に示すようにライト２２はガイド部１８よりも下方にて光を照射するので、ガイド部１８の影が切断領域１９に映ることがない。また、ライト２２と作業者の間にガイド部１８が位置することで、作業者に対する無用な光の照射を抑制することができる。 In addition, for example, in a dark place, an operator operates a light switch (not shown) in accordance with the work state to turn on the light 22 and illuminate the cutting area. At this time, as shown in FIG. 1, the light 22 emits light below the guide portion 18, so that the shadow of the guide portion 18 does not appear in the cutting area 19. In addition, since the guide portion 18 is positioned between the light 22 and the worker, unnecessary light irradiation to the worker can be suppressed.
以上、本発明を採用した上記実施例によれば以下の効果を奏する。 As mentioned above, according to the said Example which employ | adopted this invention, there exist the following effects.
（１）ハンドル３と切断領域１９との間に切断領域１９における帯鋸１２の側面と平行なガイド面１８ａを持つガイド部１８を設けたので、ガイド面１８ａを利用した高精度な作業が実現できる。 (1) Since the guide portion 18 having the guide surface 18a parallel to the side surface of the band saw 12 in the cutting region 19 is provided between the handle 3 and the cutting region 19, high-precision work using the guide surface 18a can be realized. .
（２）ガイド部１８にはガイド面１８ａとは別に傾斜面１８ｂを設け、切断中にも被切断材２１の後方を確認できるようにしたので、さらに高精度な作業を実現できる。 (2) Since the guide portion 18 is provided with the inclined surface 18b separately from the guide surface 18a so that the rear side of the material to be cut 21 can be confirmed even during cutting, a more accurate operation can be realized.
（３）駆動鋸ベース１０に重量物の一つであるモータを配置し、接続部６の従動鋸ベース１１側には重量物の一つである電池パック２を配置する、すなわち作業者が把持するハンドル３の両側に重量物が配置するように構成したので、バンドソー１の重心をハンドル３の近くとすることができ、作業性が向上する。 (3) A motor, which is one of heavy objects, is arranged on the drive saw base 10, and a battery pack 2, which is one of heavy objects, is arranged on the driven saw base 11 side of the connecting portion 6, that is, an operator holds it. Since the heavy objects are arranged on both sides of the handle 3 to be operated, the center of gravity of the band saw 1 can be close to the handle 3 and workability is improved.
（４）ハンドル３の延在方向と電池パック２の着脱方向を直交させるようにしたので、作業者が力の入れやすいハンドル３の直交方向と電池パック２の着脱方向を同一にすることができ、電池パック２の着脱作業が容易となる。 (4) Since the extending direction of the handle 3 and the attaching / detaching direction of the battery pack 2 are orthogonal to each other, the orthogonal direction of the handle 3 and the attaching / detaching direction of the battery pack 2 can be made the same. The battery pack 2 can be attached and detached easily.
（５）ガイド部１８と回転する帯鋸１２を重ねることで、帯鋸１２自体の振れ精度や曲がり状態などを確認することができ、状態に合わせて交換することで、作業性が向上する。 (5) By superimposing the rotating band saw 12 with the guide portion 18, it is possible to check the deflection accuracy or bending state of the band saw 12 itself, and the workability is improved by exchanging according to the state.
（６）ガイド面１８ａが、切断領域１９における帯鋸１２のハンドル３側側面を含む仮想面よりも僅かにハンドル３側に位置する構成とすることで、切断面を把握しやすくなり作業性が向上する。ガイド面１８ａが帯鋸１２と一致する、帯鋸１２上に位置する程突出している場合、帯鋸１２の側面を含む仮想面上から帯鋸１２の側面を目視しようとすると、ガイド部１８によって帯鋸１２の側面位置が隠れてしまい、帯鋸１２の側面位置を把握しようとバンドソー１をずらすと垂直な切断ができなくなってしまう。実施形態のように、ガイド面１８ａが帯鋸１２のハンドル３側側面を含む仮想面よりも僅かにハンドル３側に位置する構成とすることで、ガイド面１８ａと帯鋸１２の側面との位置関係、すなわち切断面を把握しやすくなる。 (6) Since the guide surface 18a is positioned slightly closer to the handle 3 side than the virtual surface including the side surface of the handle 3 of the band saw 12 in the cutting region 19, it becomes easier to grasp the cut surface and workability is improved. To do. When the guide surface 18a protrudes so as to be positioned on the band saw 12 that coincides with the band saw 12, when the side surface of the band saw 12 is viewed from the virtual surface including the side surface of the band saw 12, the side surface of the band saw 12 is guided by the guide portion 18. The position is hidden, and if the band saw 1 is shifted to grasp the side surface position of the band saw 12, the vertical cutting cannot be performed. As in the embodiment, the positional relationship between the guide surface 18a and the side surface of the band saw 12 is such that the guide surface 18a is positioned slightly closer to the handle 3 side than the virtual surface including the side surface of the handle 3 of the band saw 12. That is, it becomes easy to grasp the cut surface.
以上、実施例に従い本発明の説明をしたが、本発明は以上の実施例に限られず、種々の変更が可能である。 As mentioned above, although this invention was demonstrated according to the Example, this invention is not restricted to the above Example, A various change is possible.
例えば、ガイド面１８ａの左右方向の長さは、作業領域の左右方向寸法のほぼ半分としたが、これに限られず、被切断材２１の大きさ、形状に合わせて変更可能である。 For example, the length in the left-right direction of the guide surface 18a is approximately half of the left-right dimension of the work area, but is not limited to this, and can be changed according to the size and shape of the workpiece 21.
また、ガイド部１８は前後方向において、作業領域１９における帯鋸１２よりも後方とするよう配置したが、帯鋸１２を前方向に超えるような形状としても良く、その場合、ガイド部１８の前端と接続部６との間にスリット等のガイド面を設ければよい。 In addition, the guide portion 18 is disposed behind the band saw 12 in the work area 19 in the front-rear direction. However, the guide portion 18 may be shaped so as to exceed the band saw 12 in the front direction. In this case, the guide portion 18 is connected to the front end of the guide portion 18. What is necessary is just to provide guide surfaces, such as a slit, between the parts 6. FIG.
