Description

本発明はドライバブレードの形状を改良した釘打機に関し、特にドライバブレードの先端を分割式に構成した釘打機に関するものである。   The present invention relates to a nailing machine having an improved driver blade shape, and more particularly to a nailing machine in which the tip of a driver blade is divided.

建築内装の幅木、回り縁等の仕上建材等の取り付け部材を取り付ける際に、取付部材を接着剤により接着した後に、釘頭の小さい頭径が１〜２ｍｍのＴ形の仕上用釘又は無頭釘を使用して打ち込む工法が増えてきている。一般的に無頭釘の軸の太さは目立たず仕上りを良くするため，直径が１ｍｍ以下の釘が広く用いられており、釘の打ち込みをするために電気モータ、高圧エア、ガスを動力源とした釘打機が用いられる。釘打機においては、非常に細い無頭釘が打込み時に釘が座屈するのを防止し、釘を確実にガイド可能とするため、ドライバブレードにより打撃される釘を案内する射出路を形成するビットガイド（ガイド部）が用いられる。この従来の釘打機で用いられる釘打機は、例えば特許文献１で知られており、高圧エアで移動されるピストンの下側にドライバブレードを設けている。従来の釘打機において用いられるドライバブレードを図８にて説明する。図８は仕上用釘を打込むためのピストンクミ１０２である。ピストンクミ１０２は、ピストン３とドライバブレード１０５を組み上げた部品（組立体）であって、ドライバブレード１０５はピストン３に対して接着、ピン又はスウェージング等で結合される。ドライバブレード１０５は、ピストン３の摺動方向に長細い平板状の形状であって、その外縁が上下方向（摺動方向）に伸び、お互い平行な長手縁部１０５ａと、対向する長手縁部１０５ａを結ぶ平面部１０５ｂが形成される。ドライバブレード１０５の下端は絞り込まれて先端部１０５ｃが形成され、先端部１０５ｃが釘の頭部（後端部）を打撃する。   When attaching mounting members such as baseboards for construction interiors, finishing construction materials such as edges, etc., after attaching the mounting members with an adhesive, a T-shaped finishing nail with a small head diameter of 1-2 mm or headless There is an increasing number of construction methods using nails. Generally, the thickness of the shaft of a headless nail is not conspicuous, and nails with a diameter of 1 mm or less are widely used to improve the finish. An electric motor, high-pressure air, and gas are used as a power source to drive the nail. The nailing machine is used. In nails, a bit that forms an injection path that guides the nail hit by the driver blade in order to prevent the nail from buckling when driving a very thin headless nail and to ensure that the nail can be guided. A guide (guide part) is used. A nailing machine used in this conventional nailing machine is known from, for example, Patent Document 1, and a driver blade is provided on the lower side of a piston moved by high-pressure air. A driver blade used in a conventional nailer will be described with reference to FIG. FIG. 8 shows a piston kumi 102 for driving a finishing nail. The piston cum 102 is a component (assembly) in which the piston 3 and the driver blade 105 are assembled, and the driver blade 105 is coupled to the piston 3 by adhesion, a pin, swaging, or the like. The driver blade 105 has a flat plate shape that is long in the sliding direction of the piston 3, and its outer edge extends in the vertical direction (sliding direction). The longitudinal edge 105 a parallel to each other and the opposing longitudinal edge 105 a. Is formed. The lower end of the driver blade 105 is narrowed down to form a front end portion 105c, and the front end portion 105c strikes the head (rear end portion) of the nail.

特開２０１０−０６９５６３号公報JP 2010-066953 A

特許文献１に記載の釘打機では高耐久性であるものの、ドライバブレードの一部分、特に先端部分の摩耗・破損が起きてドライバブレードの交換が必要となる場合がある。その場合は、ピストンやドライバブレードの先端以外の大部分に異常が無くとも、ピストンとドライバブレードを含んだ組立体全体を交換しなければならない。また、メンテナンス（交換）時には、ヘッドカバーを外して、釘打機内部よりピストン及びドライバブレードを取り出さなければならず、その交換コストが発生する上に、交換に所定の手間が掛かっていた。   Although the nailing machine described in Patent Document 1 has high durability, there is a case where a part of the driver blade, particularly the tip part, is worn and damaged, and the driver blade needs to be replaced. In that case, the entire assembly including the piston and driver blade must be replaced even if there is no abnormality in most of the piston and driver blade except for the tip. Further, at the time of maintenance (replacement), it is necessary to remove the head cover and take out the piston and the driver blade from the inside of the nailing machine, which causes a replacement cost and takes a certain amount of time for replacement.

本発明は、斯かる実情に鑑み、メンテナンス時のコスト及び作業工数の低減が可能な釘打機を提供しようとするものである。   In view of such circumstances, the present invention intends to provide a nailing machine capable of reducing the maintenance cost and man-hours.

本発明の一つの特徴によれば、ドライバブレードの中央部と先端部を分割可能とし、先端部だけを交換可能に構成した。分割部は、ピストンの摺動方向及びドライバブレード平面部に垂直な方向に分割可能であり、ピストンの摺動方向には保持可能な形状とする。また、分割部の位置は、ピストンを下死点位置に移動させた状態でノーズ部を外した場合に、ドライバブレード先端部が露出して取外し可能な位置となるように決定される。   According to one aspect of the present invention, the center portion and the tip portion of the driver blade can be divided, and only the tip portion can be replaced. The dividing part can be divided in a direction perpendicular to the sliding direction of the piston and the flat part of the driver blade, and can be held in the sliding direction of the piston. Further, the position of the dividing portion is determined such that the tip of the driver blade is exposed and can be removed when the nose portion is removed with the piston moved to the bottom dead center position.

本発明によれば、ドライバブレード先端が摩耗・破損した場合、ピストン及びドライバブレードの組立体全体を交換するのでなく、ドライバブレードの先端部のみを交換することが可能となる。このため、大部分のメンテナンスにおいてドライバブレードの中央部を交換する必要がなくなり、メンテナンス時のコストを大幅に削減できる。また本発明によれば、ドライバブレード先端が摩耗・破損した場合、ノーズ部やヘッドカバーを取り外すことなく、ノーズ部だけを取り外すだけでドライバブレードの先端部を交換可能となる。これにより、メンテナンス時の工数を大幅に削減できる。   According to the present invention, when the tip of the driver blade is worn or damaged, it is possible to replace only the tip of the driver blade, instead of replacing the entire assembly of the piston and the driver blade. For this reason, it is not necessary to replace the central portion of the driver blade in most maintenance, and the maintenance cost can be greatly reduced. Further, according to the present invention, when the tip of the driver blade is worn or damaged, the tip of the driver blade can be replaced by removing only the nose without removing the nose or the head cover. Thereby, the man-hour at the time of a maintenance can be reduced significantly.

以下、本発明の実施例を図面に基づいて説明する。図１は本発明に係る釘打機の全体構成を示す全体図である。図１は本実施例に係る釘打機１の全体を示す側面図であり、一部にその断面を示す。釘打機１は、圧縮エアによってシリンダ２０内を往復動して連結された釘の先端を打ち出すピストン３と、ピストン３に連結されたドライバブレード５（５ａ、５ｂ）を含む打撃駆動手段を有する。打撃駆動手段はハウジングの前方に突出して装設されるヘッドカバー７内に配置され、連結釘を打ち出す射出部２６と、射出部２６の先端に形成されるノーズ部８と、ヘッドカバー７から直交状に装設されたハンドル１３と、ハンドル１３にほぼ平行に配置され、連結釘を収納し、射出部２６内に一本ずつ連結釘を供給するマガジン４が設けられる。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view showing an overall configuration of a nailing machine according to the present invention. FIG. 1 is a side view showing the entirety of a nailing machine 1 according to the present embodiment, partially showing a cross section thereof. The nail driver 1 has a striking drive means including a piston 3 for driving a tip of a nail connected by reciprocating in a cylinder 20 with compressed air, and a driver blade 5 (5a, 5b) connected to the piston 3. . The striking drive means is disposed in the head cover 7 that protrudes from the front of the housing and is installed. An installed handle 13 and a magazine 4 which is arranged substantially parallel to the handle 13 and which stores the connecting nails and supplies the connecting nails one by one into the injection portion 26 are provided.

ハンドル１３の取付部付近には、釘打機１の打込み動作を制御するものであって作業者の手の指で引き操作されるトリガ１４が設けられる。コンタクトアーム１５は、ビットガイド１６の前方に位置し、ビットガイド１６によって上下摺動可能に支持され、上方は往復動可能な連結アーム１７に接続される。連結アーム１７の上端部はトリガ１４近傍まで伸び、コンタクトアーム１５と連結アーム１７は一体となって上下方向に摺動可能とされる。コンタクトアーム１５の先端部（下端部）１５ａには、打ち出される連結釘を案内するための射出路が設けられる。   A trigger 14 that controls the driving operation of the nail driver 1 and is pulled by a finger of an operator's hand is provided near the attachment portion of the handle 13. The contact arm 15 is positioned in front of the bit guide 16 and is supported by the bit guide 16 so as to be slidable up and down. The contact arm 15 is connected to a connecting arm 17 which can reciprocate. The upper end portion of the connecting arm 17 extends to the vicinity of the trigger 14, and the contact arm 15 and the connecting arm 17 are integrally slidable in the vertical direction. The tip end (lower end) 15a of the contact arm 15 is provided with an injection path for guiding the connecting nail to be driven out.

トリガ１４は、回動軸１８を支点として回動操作が可能なごとくハウジングに枢支され、スイッチ１９の中央部には、下方に突出し上下に摺動可能に支持されたプランジャ１９ａが位置する。プランジャ１９ａが下死点（伸びた状態）にある時は、釘打機１はＯＦＦ状態を保ち、プランジャ１９ａが下死点から上死点（縮んだ状態）に移動する過程においてスイッチ１９がＯＮとなり、釘打機１の打ち込み動作が開始される。トリガ１４は、ほぼ中央部においてプランジャ１９ａの先端と当接する。   The trigger 14 is pivotally supported by the housing so that it can be rotated about the rotation shaft 18, and a plunger 19 a that protrudes downward and is supported so as to be slidable up and down is located at the center of the switch 19. When the plunger 19a is at the bottom dead center (extended state), the nail driver 1 is kept in the OFF state, and the switch 19 is turned on while the plunger 19a moves from the bottom dead center to the top dead center (contracted state). Thus, the driving operation of the nail driver 1 is started. The trigger 14 comes into contact with the tip of the plunger 19a at substantially the center.

図示しない無頭釘は、例えば長さが約１０ｍｍ〜６０ｍｍで、軸径が０．６〜０．７ｍｍであり、軸径が非常に細く、釘頭径が釘の軸径と同じである。このピン状の釘が接着剤等で１００本程度並列に連結され、連結無頭釘としてマガジン４にセットされる。本実施例においてドライバブレード５は、ドライバブレード中央部５ａとドライバブレード先端部５ｂとの２つの部品から構成される。ドライバブレード中央部５ａとドライバブレード先端部５ｂは分割可能であり、その分割部はピストン３をシリンダ２０内の下死点に位置させた状態でノーズ部８を外した場合に、ドライバブレード先端部５ｂが取外し可能な位置になるように構成される。   The headless nail (not shown) has a length of about 10 mm to 60 mm, a shaft diameter of 0.6 to 0.7 mm, a very thin shaft diameter, and a nail head diameter that is the same as the shaft diameter of the nail. About 100 of these pin-shaped nails are connected in parallel with an adhesive or the like, and set in the magazine 4 as a connected headless nail. In this embodiment, the driver blade 5 is composed of two parts, a driver blade center portion 5a and a driver blade tip portion 5b. The driver blade center portion 5a and the driver blade tip portion 5b can be divided, and the divided portion is the tip portion of the driver blade when the nose portion 8 is removed with the piston 3 positioned at the bottom dead center in the cylinder 20. 5b is configured to be a removable position.

図２は本実施例に係るピストンクミ２の側面図である。ドライバブレード中央部５ａとドライバブレード先端部５ｂは、分割部６において分割可能に構成される。ドライバブレード中央部５ａとドライバブレード先端部５ｂを連結させた時のドライバブレード５の外観形状は、図８で示した従来のドライバブレード１０５と同等の形状となる。ドライバブレード中央部５ａとドライバブレード先端部５ｂの分割は、ドライバブレード先端部５ｂをドライバブレード中央部５ａに対して射出方向と垂直方向（図２の紙面に垂直方向）に移動させることで行う。このように分割のための移動方向が、射出方向及び反射出方向と一致しないように構成したこと、射出方向に対して９０度の方向として射出時にドライバブレードに伝わる力の分力が分割方向に作用しないように構成した。また、射出時にドライバブレード先端部５ｂががたつかないように分割部６においてお互いがフック状として隙間なく良好に密接するように構成した。   FIG. 2 is a side view of the piston kumi 2 according to the present embodiment. The driver blade center portion 5a and the driver blade tip portion 5b are configured to be split by the split portion 6. The external shape of the driver blade 5 when the driver blade center portion 5a and the driver blade tip portion 5b are connected is the same shape as the conventional driver blade 105 shown in FIG. The driver blade center portion 5a and the driver blade tip portion 5b are divided by moving the driver blade tip portion 5b with respect to the driver blade center portion 5a in a direction perpendicular to the injection direction (perpendicular to the paper surface of FIG. 2). In this way, the movement direction for division does not coincide with the emission direction and the reflection direction, and the component force of the force transmitted to the driver blade at the time of injection is 90 degrees with respect to the emission direction. It was configured not to work. Further, the split blades 6 are configured to be in close contact with each other in a hook shape so that the driver blade tip 5b does not rattle at the time of injection.

図３はドライバブレード中央部５ａの分割部の形状を示す拡大図であり、図４はドライバブレード先端部５ｂの分割部の形状を示す拡大図である。ドライバブレード中央部５ａの分割部にはピストン３の摺動方向に保持可能な突出部９が形成され、同様にしてドライバブレード先端部５ｂの分割部にはピストン３の摺動方向に保持可能な突出部１０が形成される。突出部９、１０には、ピストン３の摺動方向と垂直かつドライバブレード５の平面部に平行な方向に保持可能な掛止部１１、１２が形成される。本実施例では突出部９、掛止部１１によって鍵状又はフック状の形状となるようにし、同様にして突出部１０、掛止部１２は、突出部９、掛止部１１と対応する鍵状又はフック状の形状に構成される。尚、本実施例では、ドライバブレード５の平面部５ｃのいずれかの面に、射出方向と平行に伸びる突出部又は／及び凹部を設けることを説明していないが、突出部や凹部を設けたドライバブレードに本実施例の分割構造を適用しても本実施例と同一の効果を奏することは言うまでもない。以上のように、本発明によれば、メンテナンス時のコスト及び工数の低減が可能な釘打機を提供することができる。   FIG. 3 is an enlarged view showing the shape of the divided portion of the driver blade central portion 5a, and FIG. 4 is an enlarged view showing the shape of the divided portion of the driver blade tip portion 5b. A protruding portion 9 that can be held in the sliding direction of the piston 3 is formed in the divided portion of the driver blade central portion 5a, and similarly, the divided portion of the driver blade tip portion 5b can be held in the sliding direction of the piston 3. A protruding portion 10 is formed. The protrusions 9 and 10 are formed with latching portions 11 and 12 that can be held in a direction perpendicular to the sliding direction of the piston 3 and parallel to the flat portion of the driver blade 5. In the present embodiment, the protruding portion 9 and the hooking portion 11 form a key-like or hook-like shape. Similarly, the protruding portion 10 and the hooking portion 12 are the keys corresponding to the protruding portion 9 and the hooking portion 11. Or a hook-like shape. In the present embodiment, it is not described that a protruding portion or / and a recessed portion extending in parallel with the injection direction is provided on any surface of the flat portion 5c of the driver blade 5, but a protruding portion or a recessed portion is provided. It goes without saying that the same effects as in this embodiment can be obtained even if the divided structure of this embodiment is applied to the driver blade. As described above, according to the present invention, it is possible to provide a nailing machine capable of reducing costs and man-hours during maintenance.

次に図５〜図７を用いて本発明の第２の実施例を説明する。図５は本発明の第２の実施例に係るドライバブレード中央部５５ａ及びドライバブレード先端部５５ｂの拡大図である。第１の実施例ではピストン３の摺動方向と、ピストン３の摺動方向と垂直かつドライバブレード５５の平面部に平行な方向に保持可能な突出部６２及び凹部６１を設けている。図６に示すようにドライバブレード中央部５５ａは先端に凹部６１が設けられる。凹部６１は、射出方向に対して９０度の方向として射出時にドライバブレードに伝わる力の分力が分割方向に作用しないように構成した垂直面５９のほぼ中央付近に設けられる。また、図７にて示されるドライバブレード先端部５５ｂの突出部６２は、射出方向に対して９０度の方向として射出時にドライバブレードに伝わる力の分力が分割方向に作用しないように構成した垂直面６０のほぼ中央付近に設けられる。第２の実施例のような分割構造を採用しても、第１の実施形態と同様の効果を奏することは言うまでもない。以上のように、本発明によれば、メンテナンス時のコスト及び工数の低減が可能な釘打機を提供することができる。   Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is an enlarged view of the driver blade central portion 55a and the driver blade tip portion 55b according to the second embodiment of the present invention. In the first embodiment, there are provided a projecting portion 62 and a recessed portion 61 that can be held in the sliding direction of the piston 3 and in a direction perpendicular to the sliding direction of the piston 3 and parallel to the flat portion of the driver blade 55. As shown in FIG. 6, the driver blade central portion 55a is provided with a recess 61 at the tip. The recess 61 is provided in the vicinity of the center of the vertical surface 59 configured so that the component force of the force transmitted to the driver blade at the time of injection does not act in the dividing direction as a direction of 90 degrees with respect to the injection direction. Further, the protrusion 62 of the driver blade tip 55b shown in FIG. 7 is configured so that the component force of the force transmitted to the driver blade at the time of injection does not act in the dividing direction as a direction of 90 degrees with respect to the injection direction. It is provided near the center of the surface 60. Needless to say, the same effects as those of the first embodiment can be obtained even when the divided structure as in the second embodiment is employed. As described above, according to the present invention, it is possible to provide a nailing machine capable of reducing costs and man-hours during maintenance.

以上、本発明を示す実施形態に基づき説明したが、本発明は上述の形態に限定されるものではなく、その趣旨を逸脱しない範囲内で種々の変更が可能である。例えば、本発明の釘打機の動力源としては、圧縮空気だけでなく、電気またはガス等種々のものが利用可能である。   As mentioned above, although demonstrated based on embodiment which shows this invention, this invention is not limited to the above-mentioned form, A various change is possible within the range which does not deviate from the meaning. For example, as a power source of the nailing machine of the present invention, not only compressed air but also various things such as electricity or gas can be used.
