(First embodiment of the present invention)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. This embodiment will be described using an electro-pneumatic nailing machine as an example of an electro-pneumatic driving tool. As shown in FIG. 1, the nailing machine 100 generally includes a main body 101 as a tool main body, a long handle 103 that is gripped by an operator, and a stopper that is driven into a workpiece. And a magazine 105 loaded with the nail n. The handle portion 103 projects (extends) from the side surface portion on the one end side (upper side in the drawing) of the main body portion 101 in the long axis direction (up and down direction in FIG. 1) to the side (right side in the drawing) intersecting the long axis direction. Present) is provided integrally. A rechargeable battery pack 110 serving as a power source for the drive motor 111 is attached to the extending side end of the handle portion 103. FIG. 1 shows a state in which the nailing machine 100 faces downward, that is, a state in which the distal end portion (lower end portion in the drawing) of the main body 101 is directed to the workpiece. For this reason, the downward direction in FIG. 1 is the driving (launching) direction (major axis direction) of the nail n, which is the direction in which the driver 125 hits the nail n. For convenience of explanation, the front end side (lower side in the drawing) of the main body 101 is referred to as the front, and the opposite side (the handle portion 103 side) is referred to as the rear. Further, the connection side of the handle portion 103 with the main body portion 101 is referred to as the upper side (the left side in the drawing), and the extended end side of the handle portion 103 is referred to as the lower side (the right side in the drawing). The handle portion 103 corresponds to the “handle” in the present invention.
 本体部101は、釘打込み機構120の打撃用シリンダ121および圧縮装置130の圧縮用シリンダ131が一体状に形成された本体ハウジング107と、駆動モータ111が収容されたモータハウジング109とを主体として構成される。ハンドル部103は、本体部101の後端側、具体的には本体ハウジング107における圧縮用シリンダ131の後端側に連接されるとともに、その中心軸Hが打撃用シリンダ121の中心軸Qに対して直交するように下方へと延在されている。モータハウジング109は、本体ハウジング107の先端側、従ってハンドル部103の前方において、当該ハンドル部103に対し所定の間隔を置いて概ね平行に配置されるとともに、長軸方向の一端側が本体ハウジング107に連接され、他端側がハンドル部103の突出側端部に連接されている。 The main body 101 is mainly composed of a main body housing 107 in which a striking cylinder 121 of the nail driving mechanism 120 and a compression cylinder 131 of the compression device 130 are integrally formed, and a motor housing 109 in which a drive motor 111 is accommodated. Is done. The handle portion 103 is connected to the rear end side of the main body portion 101, specifically, to the rear end side of the compression cylinder 131 in the main body housing 107, and its central axis H is relative to the central axis Q of the striking cylinder 121. Are extended downward so as to be orthogonal to each other. The motor housing 109 is disposed substantially parallel to the handle portion 103 at a predetermined interval on the front end side of the main body housing 107, and thus in front of the handle portion 103, and one end side in the long axis direction is disposed on the main body housing 107. The other end side is connected to the projecting side end portion of the handle portion 103.
 本体ハウジング107における打撃用シリンダ121の先端部(図1において下方)には、釘nの射出口を構成するドライバガイド141が配置されている。マガジン105は、本体部101の最先端側、すなわちモータハウジング109の前方に配置され、その長軸方向が駆動モータ111の回転軸と概ね平行となるように設定されており、釘供給側先端部がドライバガイド141に連結され、他端側がモータハウジング109の他端部に連接されている。なお、マガジン105には、便宜上図示を省略するが、釘nを供給方向(図1において左方)に押すためのプッシャプレートが備えられ、このプッシャプレートによって釘nがドライバガイド141の打込み通路141aに打込み方向と交差する方向から1本ずつ供給されるよう構成されている。打込み通路141aは、ドライバ125が直線動作して釘nを打込む際の通路を構成するものであり、本発明における「打込み部の動作線」に対応する。 A driver guide 141 that constitutes an injection port for the nail n is disposed at the tip of the impact cylinder 121 in the main body housing 107 (downward in FIG. 1). The magazine 105 is disposed on the most distal side of the main body 101, that is, in front of the motor housing 109, and is set so that the major axis direction thereof is substantially parallel to the rotation axis of the drive motor 111. Is connected to the driver guide 141, and the other end is connected to the other end of the motor housing 109. Although not shown for convenience, the magazine 105 is provided with a pusher plate for pushing the nail n in the supply direction (leftward in FIG. 1), and the nail n is driven into the driving guide 141a of the driver guide 141 by the pusher plate. Are supplied one by one from the direction intersecting the driving direction. The driving path 141a constitutes a path when the driver 125 moves linearly to drive the nail n, and corresponds to the “operation line of the driving section” in the present invention.
 本実施の形態では、釘打込み機構120の打撃用シリンダ121と、圧縮装置130の圧縮用シリンダ131とは、それらの中心軸が互いに同一軸線上に配置された構成とされる。すなわち、圧縮用シリンダ131は、図2に示すように、断面略ドーナッツ状に形成されており、圧縮用シリンダ131の内部空間である圧縮室131aが打撃用シリンダ121の外側を取り囲むように形成されている。すなわち、打撃用シリンダ121と圧縮用シリンダ131とは、内外に同軸で配置された二重筒形に形成されている。これにより圧縮用シリンダ131と打撃用シリンダ121とは、釘打機100を前方あるいは後方から見たときの、圧縮用シリンダ131の中心軸方向視において径方向に関して互いに重なる配置とされる。圧縮用シリンダ131は、本発明における「第1シリンダ」に対応し、打撃用シリンダ121は、本発明における「第2シリンダ」に対応する。 In the present embodiment, the hitting cylinder 121 of the nail driving mechanism 120 and the compression cylinder 131 of the compression device 130 are configured such that their central axes are arranged on the same axis. That is, as shown in FIG. 2, the compression cylinder 131 is formed in a substantially donut shape in cross section, and is formed so that the compression chamber 131 a that is the internal space of the compression cylinder 131 surrounds the outside of the impact cylinder 121. ing. That is, the striking cylinder 121 and the compression cylinder 131 are formed in a double cylinder shape that is coaxially arranged inside and outside. As a result, the compression cylinder 131 and the impact cylinder 121 are arranged so as to overlap each other in the radial direction when the nailing machine 100 is viewed from the front or the rear as viewed in the central axis direction of the compression cylinder 131. The compression cylinder 131 corresponds to the “first cylinder” in the present invention, and the striking cylinder 121 corresponds to the “second cylinder” in the present invention.
 打撃用シリンダ121内には、釘nを打撃動作する打撃用ピストン123が長軸方向に摺動自在に収容されている。打撃用ピストン123は、打撃用シリンダ121内に摺動自在に収容されたピストン本体部124と、当該ピストン本体部124に一体状に設けられ、釘nを打撃動作するための長尺状のドライバ125とからなり、打撃用シリンダ121の長軸方向に直線状に移動し、ドライバ125がドライバガイド141の打込み通路141a内を前方に移動して釘nを打込む作動部材として機能する。打撃用ピストン123は、本発明における「第2ピストン」に対応し、ピストン本体部124は、本発明における「摺動部」に対応し、ドライバ125は、本発明における「打込み部」に対応する。打撃用シリンダ121および打撃用ピストン123によって釘打込み機構120が構成される。 A striking piston 123 that strikes the nail n is accommodated in the striking cylinder 121 so as to be slidable in the long axis direction. The striking piston 123 includes a piston main body 124 that is slidably accommodated in the striking cylinder 121, and a long driver for striking the nail n, which is integrally provided in the piston main body 124. 125, which moves linearly in the long axis direction of the hitting cylinder 121, and functions as an operating member that the driver 125 moves forward in the driving passage 141a of the driver guide 141 and drives the nail n. The striking piston 123 corresponds to the “second piston” in the present invention, the piston main body portion 124 corresponds to the “sliding portion” in the present invention, and the driver 125 corresponds to the “driving portion” in the present invention. . A nail driving mechanism 120 is constituted by the hitting cylinder 121 and the hitting piston 123.
 圧縮装置130の圧縮用シリンダ131内には、リング状の圧縮用ピストン133が長軸方向に摺動自在に収容され、当該圧縮用ピストン133は、駆動モータ111からラック・ピニオン機構116を介して駆動される。駆動モータ111は回転軸線が打撃用シリンダ121の中心軸Qと概ね直交し、かつハンドル部103の中心軸Hに対して概ね平行となるようにモータハウジング109内に配置されている。そして、駆動モータ111の回転出力は、歯車減速機構113によって適宜減速されるとともに、運動変換機構としてのラック・ピニオン機構116によって直線運動に変換されて圧縮用ピストン133を直線状に往復運動させる。これにより圧縮用シリンダ131の内部空間である圧縮室131aの容積が変化し、圧縮用ピストン133が圧縮室131aを減少する後方側へと移動することで圧縮室131aの空気を圧縮する。すなわち、本実施の形態では、圧縮装置130として、圧縮用シリンダ131、圧縮用ピストン133およびラック・ピニオン機構116を主体として構成されるレシプロ式の圧縮装置が用いられている。なお、圧縮用ピストン133の往動と復動の切替えについては、例えば駆動モータ111の回転方向を切替えることで可能とされる。 A ring-shaped compression piston 133 is accommodated in the compression cylinder 131 of the compression device 130 so as to be slidable in the long axis direction. The compression piston 133 is connected to the drive motor 111 via the rack and pinion mechanism 116. Driven. The drive motor 111 is disposed in the motor housing 109 such that the rotational axis is substantially perpendicular to the central axis Q of the impact cylinder 121 and is substantially parallel to the central axis H of the handle portion 103. The rotational output of the drive motor 111 is appropriately decelerated by the gear reduction mechanism 113 and converted into a linear motion by a rack and pinion mechanism 116 as a motion conversion mechanism to cause the compression piston 133 to reciprocate linearly. As a result, the volume of the compression chamber 131a, which is the internal space of the compression cylinder 131, changes, and the compression piston 133 moves to the rear side where the compression chamber 131a decreases, thereby compressing the air in the compression chamber 131a. That is, in the present embodiment, a reciprocating type compression device mainly composed of the compression cylinder 131, the compression piston 133, and the rack and pinion mechanism 116 is used as the compression device 130. Note that the forward and backward movements of the compression piston 133 can be switched by switching the rotation direction of the drive motor 111, for example.
 なお、ラック・ピニオン機構116は、歯車減速機構113によって減速回転される回転軸116aと、回転軸116aの外周面に設けられたピニオン116bと、圧縮用ピストン133に設けられ、ピニオン116bと常時に噛み合い係合するラック116cとによって構成されており、圧縮用シリンダ131の前方領域において、本体ハウジング107の内部に収容されている。 Note that the rack and pinion mechanism 116 is provided with a rotation shaft 116a that is decelerated and rotated by the gear reduction mechanism 113, a pinion 116b that is provided on the outer peripheral surface of the rotation shaft 116a, and a compression piston 133 that is constantly connected to the pinion 116b. The rack 116c is engaged with and engaged with the rack 116c, and is housed inside the main body housing 107 in the front region of the compression cylinder 131.
 なお、駆動モータ111は、ハンドル部103に支軸103cを支点にして回動自在に設けた操作部材としてのトリガ103aおよび本体部101の先端領域に設けられる操作部材としてのコンタクトアーム(本実施の形態では、ドライバガイド141がコンタクトアームの機能を兼ね備える構成とされる)によって駆動と停止が制御(操作)される構成とされる。すなわち、ハンドル部103には、手指により操作可能な打込み操作部としてのトリガ103aと、当該トリガ103aが引き操作されることで駆動モータ111を通電駆動するオン状態に投入され、引き操作が解除されることで駆動モータ111を停止するオフ状態に切替わるモータ駆動用のトリガスイッチ103bが設置されている。 The drive motor 111 includes a trigger 103a as an operation member provided rotatably on the handle portion 103 with a support shaft 103c as a fulcrum, and a contact arm as an operation member provided in a distal end region of the main body 101 (this embodiment). In the embodiment, the driving and stopping are controlled (operated) by the driver guide 141 having a function of a contact arm). That is, the handle 103 is put into an ON state in which the drive motor 111 is energized and driven by pulling the trigger 103a as a driving operation unit that can be operated by a finger, and the pulling operation is released. Thus, a trigger switch 103b for driving the motor that is switched to an OFF state in which the drive motor 111 is stopped is provided.
 他方、コンタクトアームを兼ねるドライバガイド141(以下の説明では、ドライバガイド141がコンタクトアームとして機能する場合に限り、コンタクトアーム141という)は、釘nの長軸方向(打撃方向)に移動可能に取り付けられ、便宜上図示を省略するバネにより先端側に突出するように付勢されている。コンタクトアーム141が突出位置にあるときは、便宜上図示を省略するモータ駆動用のコンタクトアームスイッチがオフ状態とされ、コンタクトアーム141が本体ハウジング107側に移動されたときに、コンタクトアームスイッチがオン状態とされる。そして、駆動モータ111は、トリガスイッチ103bとコンタクトアームスイッチが共にオン状態に切替えられたときに通電駆動され、いずれか一方、又は双方がオフ状態に切替えられたとき停止される。 On the other hand, a driver guide 141 that also serves as a contact arm (in the following description, the contact arm 141 is referred to only when the driver guide 141 functions as a contact arm) is attached to be movable in the major axis direction (striking direction) of the nail n. For the sake of convenience, it is biased so as to protrude toward the tip side by a spring (not shown). When the contact arm 141 is in the protruding position, the contact arm switch for driving the motor (not shown) is turned off for convenience, and the contact arm switch is turned on when the contact arm 141 is moved to the main body housing 107 side. It is said. The drive motor 111 is energized when both the trigger switch 103b and the contact arm switch are switched on, and is stopped when one or both are switched off.
 本体ハウジング107には、圧縮用シリンダ131の圧縮室131aと打撃用シリンダ121の内部とを連通する圧縮空気供給経路としての連通路135と、当該連通路135を開放および閉鎖する開閉装置としてのメインバルブ137が設けられている。釘打機100は、図1に示すように、打撃用ピストン123が最後端位置(図示上端位置)へと移動され、かつ圧縮用ピストン133が最前端位置(下死点)へと移動された状態が初期位置として定められている。メインバルブ137は、圧縮用シリンダ131のシリンダヘッド側に設けられるとともに、非通電時に閉じる電気的駆動弁としてのノーマルクローズタイプのソレノイドバルブによって構成されており、圧縮用ピストン133が最後端位置へと移動された上死点付近において連通路135を開放する構成とされる。従って、メインバルブ137が連通路135を開放すると、圧縮用ピストン133で圧縮された圧縮室131a内の圧縮空気が打撃用シリンダ121へと供給され、この供給された圧縮空気によって打撃用ピストン123が前方へと移動され、ドライバ125によって釘nを打撃し、被加工材に釘nを打込む。 The main body housing 107 includes a communication path 135 as a compressed air supply path that allows the compression chamber 131a of the compression cylinder 131 and the inside of the impact cylinder 121 to communicate with each other, and a main opening / closing device that opens and closes the communication path 135. A valve 137 is provided. As shown in FIG. 1, in the nail driver 100, the striking piston 123 is moved to the rearmost position (the upper end position in the figure), and the compression piston 133 is moved to the frontmost end position (the bottom dead center). The state is defined as the initial position. The main valve 137 is provided on the cylinder head side of the compression cylinder 131 and is constituted by a normally closed type solenoid valve as an electrically driven valve that closes when no power is supplied. The compression piston 133 is moved to the end position. The communication path 135 is opened in the vicinity of the moved top dead center. Therefore, when the main valve 137 opens the communication path 135, the compressed air in the compression chamber 131a compressed by the compression piston 133 is supplied to the striking cylinder 121, and the striking piston 123 is moved by the supplied compressed air. The nail n is hit by the driver 125, and the nail n is driven into the workpiece.
 打撃用シリンダ121には、釘打ち作業終了時、あるいは終了直前において、打撃用シリンダ121内の圧縮空気を大気中に逃がす逆止弁127a付きの逃し孔127が形成されている。当該逃し孔127は、打撃用ピストン123が最前端位置へと移動されたときに、当該打撃用ピストン123のピストン本体部124が通過して打撃用シリンダ121内部を大気に連通させる位置に設けられる。すなわち、ドライバ125による釘打ちが終了すると同時に大気と打撃用シリンダ121の内部とを連通する構成とされ、これによって打撃終了と同時に打撃用シリンダ121内の圧縮空気は、大気中に放出される。なお、逆止弁127aは、打撃用シリンダ121の外側において、逃し孔127を塞ぐように配置された板バネによって構成されており、大気中の空気が逃し孔127から打撃用シリンダ121内に流入(逆流)することを規制する。 The hitting cylinder 121 is formed with an escape hole 127 with a check valve 127a for releasing the compressed air in the hitting cylinder 121 into the atmosphere at the end of the nail driving operation or just before the end of the nail driving operation. The relief hole 127 is provided at a position where when the striking piston 123 is moved to the foremost position, the piston main body 124 of the striking piston 123 passes and the interior of the striking cylinder 121 communicates with the atmosphere. . In other words, the configuration is such that the atmosphere communicates with the inside of the striking cylinder 121 at the same time as the nail driving by the driver 125 is completed, whereby the compressed air in the striking cylinder 121 is released into the atmosphere at the same time as the striking is completed. The check valve 127 a is configured by a leaf spring arranged so as to close the escape hole 127 outside the impact cylinder 121, and air in the atmosphere flows into the impact cylinder 121 from the escape hole 127. (Backflow) is regulated.
 圧縮動作後の圧縮用ピストン133が前方へと移動すると、圧縮室131aの容積が増加され、これによって当該圧縮室131aおよび打撃用シリンダ121内が負圧化し、当該負圧によって打撃用ピストン123が後方へと移動される構成とされる。また、圧縮用シリンダ131には、圧縮用ピストン133が初期位置としての最前端位置(下死点)に置かれたときに、当該圧縮用ピストン133のピストン本体部133aが通過することで大気と圧縮室131aとを連通する外気補給口139が設けられる。そして、メインバルブ137は、圧縮用ピストン133のピストン本体部133aが外気補給口139を通過して最前端位置(下死点)に置かれたとき、連通路135を閉鎖するように構成される。このように、本実施の形態に係る釘打機100による釘打ち動作は、圧縮用ピストン133が一往復すると、打撃用ピストン123のドライバ125が一回の釘打込み動作を行うように構成されている。 When the compression piston 133 after the compression operation moves forward, the volume of the compression chamber 131a is increased, whereby the compression chamber 131a and the inside of the impact cylinder 121 become negative pressure, and the impact pressure causes the impact piston 123 to move. It is set as the structure moved to back. Further, when the compression piston 133 is placed at the foremost end position (bottom dead center) as an initial position, the compression cylinder 133 passes through the piston main body 133a of the compression piston 133 so that the compression cylinder 133 passes through the atmosphere. An outside air supply port 139 that communicates with the compression chamber 131a is provided. The main valve 137 is configured to close the communication passage 135 when the piston main body 133a of the compression piston 133 passes the outside air supply port 139 and is placed at the foremost end position (bottom dead center). . Thus, the nail driving operation by the nail driver 100 according to the present embodiment is configured such that when the compression piston 133 reciprocates once, the driver 125 of the driving piston 123 performs one nail driving operation. Yes.
 次に上記のように構成された釘打機100の作用および使用方法につき説明する。初期状態において、コンタクトアーム141が被加工材に押し付けられてコンタクトアームスイッチがオン状態とされるとともに、トリガ103aが引き操作されてトリガスイッチ103bがオン状態に切替えられると、駆動モータ111が通電駆動される。これによって歯車減速機構113を介してラック・ピニオン機構116が駆動され、圧縮用ピストン133が後方へと移動を開始し、外気補給口139による圧縮室131aと大気との連通が遮断される。このとき、メインバルブ137は、連通路135を閉鎖しているため、圧縮室131aの容積が減少され、圧縮室131a内に閉じ込められた空気が圧縮される。 Next, the operation and usage of the nailing machine 100 configured as described above will be described. In the initial state, when the contact arm 141 is pressed against the workpiece and the contact arm switch is turned on, and the trigger 103a is pulled and the trigger switch 103b is turned on, the drive motor 111 is energized. Is done. As a result, the rack and pinion mechanism 116 is driven via the gear reduction mechanism 113, the compression piston 133 starts moving backward, and the communication between the compression chamber 131a and the atmosphere by the outside air supply port 139 is blocked. At this time, since the main valve 137 closes the communication path 135, the volume of the compression chamber 131a is reduced, and the air trapped in the compression chamber 131a is compressed.
 圧縮用ピストン133が最後端位置に接近した圧縮動作の上死点付近でメインバルブ137が通電されて連通路135を開放する。このため、圧縮室131a内の圧縮空気が連通路135を経て打撃用シリンダ121内へと供給され、当該圧縮空気によって打撃用ピストン123が前方へ移動される。そして、前方へと移動された打撃用ピストン123のドライバ125がドライバガイド141の打込み通路141aに待機している釘nを打撃し、これを被加工材に打込む。 The main valve 137 is energized to open the communication path 135 near the top dead center of the compression operation when the compression piston 133 approaches the rear end position. For this reason, the compressed air in the compression chamber 131a is supplied into the striking cylinder 121 through the communication path 135, and the striking piston 123 is moved forward by the compressed air. Then, the driver 125 of the hammering piston 123 moved forward strikes the nail n waiting in the hammering passage 141a of the driver guide 141, and hammers it into the workpiece.
 打撃用ピストン123のピストン本体部124が逃し孔127を通過すると、打撃用シリンダ121内の圧縮空気が逃し孔127を通して大気中に放出される。圧縮用ピストン133が最後端位置へと移動されると、駆動モータ111の回転方向が切替えられ、圧縮用ピストン133は、移動方向を転換して前方へと移動される。この前方への移動により圧縮室131aの容積が増加されて当該圧縮室131aが負圧化され、当該負圧が連通路135および打撃用シリンダ121内を通じて打撃用ピストン123に作用する。これによって打撃用ピストン123が吸引され、後方の打撃前の位置へと戻される。 When the piston main body 124 of the striking piston 123 passes through the escape hole 127, the compressed air in the striking cylinder 121 is released into the atmosphere through the relief hole 127. When the compression piston 133 is moved to the rearmost position, the rotation direction of the drive motor 111 is switched, and the compression piston 133 is moved forward while changing the movement direction. Due to this forward movement, the volume of the compression chamber 131 a is increased and the compression chamber 131 a is made negative, and the negative pressure acts on the striking piston 123 through the communication path 135 and the striking cylinder 121. As a result, the striking piston 123 is sucked and returned to the rear position before striking.
 なお、圧縮用ピストン133が初期位置としての圧縮開始前の位置(下死点)に復帰すると、外気補給口139が開き、圧縮室131a内に大気中の空気が補給される。また、圧縮用ピストン133が圧縮開始前の位置に復帰すると、トリガスイッチ103bおよびコンタクトアームスイッチのオン状態に維持されていても、駆動モータ111に対する通電が遮断され、駆動モータ111が停止され、同時にメインバルブ137に対する通電が遮断され、当該メインバルブ137が連通路135を閉鎖する。かくして、釘打ち動作の1サイクルが終了する。 When the compression piston 133 returns to the position before the compression start (bottom dead center) as the initial position, the outside air supply port 139 is opened, and air in the atmosphere is supplied into the compression chamber 131a. Further, when the compression piston 133 returns to the position before the compression start, even if the trigger switch 103b and the contact arm switch are kept on, the energization to the drive motor 111 is cut off and the drive motor 111 is stopped simultaneously. The power supply to the main valve 137 is cut off, and the main valve 137 closes the communication path 135. Thus, one cycle of the nailing operation is completed.
 なお、駆動モータ111に対する回転方向の制御、およびメインバルブ137に対する通電とその遮断については、便宜上図示を省略するが、例えば、圧縮用ピストンク133の位置等を適宜位置検知センサーによって検知し、当該検知信号に基づき、少なくとも駆動モータ111を制御するべく設けられる制御装置(コントローラ)によって制御されるように構成される。 Although the illustration of the rotation direction control for the drive motor 111 and the energization to the main valve 137 and the interruption thereof is omitted for the sake of convenience, for example, the position of the compression piston 133 is appropriately detected by a position detection sensor, and the detection is performed. Based on the signal, it is configured to be controlled by at least a control device (controller) provided to control the drive motor 111.
 さて、本実施の形態においては、圧縮用シリンダ131の中心軸と打撃用シリンダ121の中心軸が同一軸線上に配置される構成としている。すなわち、圧縮用シリンダ131を断面ドーナッツ状に形成して打撃用シリンダ121の外側に配置した、二重筒形に配置する構成としている。これにより、圧縮用シリンダ131と打撃用シリンダ121とを、径方向において互いに接近した状態での配置とされ、それに伴い圧縮用シリンダ131に対するハンドル部103の連接部位も打撃用シリンダ121の中心軸Qに接近する。ハンドル部103の延在側端部には、バッテリパック110が装着されている。従って、本実施の形態によれば、ハンドル部103の長さを変えずに、打撃用シリンダ121の中心軸Qからバッテリパック110の端面までの上下方向(図1の左右方向)長さを縮小することができ、これによって釘打機100の上下方向(図1の左右方向)のコンパクト化が可能となる。 In the present embodiment, the central axis of the compression cylinder 131 and the central axis of the striking cylinder 121 are arranged on the same axis. In other words, the compression cylinder 131 is formed in a donut cross-sectional shape and disposed outside the striking cylinder 121, and is arranged in a double cylinder shape. Thus, the compression cylinder 131 and the impact cylinder 121 are arranged in a state in which they are close to each other in the radial direction, and accordingly, the connecting portion of the handle portion 103 with respect to the compression cylinder 131 is also the central axis Q of the impact cylinder 121. To approach. A battery pack 110 is attached to the end of the handle portion 103 on the extending side. Therefore, according to the present embodiment, the length in the vertical direction (the horizontal direction in FIG. 1) from the central axis Q of the striking cylinder 121 to the end surface of the battery pack 110 is reduced without changing the length of the handle portion 103. Thus, the nailing machine 100 can be made compact in the vertical direction (left-right direction in FIG. 1).
 また、本実施の形態によれば、バッテリパック110が装着された状態での機体の重心位置を打撃用シリンダ121の中心軸Q(打撃中心線)から遠ざけることなく、ハンドル部103を打撃用シリンダ121の中心軸線に近づけることが可能となる。通常、作業者はハンドル部103を握り釘打機100に前方への押圧力を作用させつつ人差指で打込み操作部としてのトリガ103aを引き操作することで釘打ち作業を行う。ドライバ125が釘nを被加工材に打込んだとき、本体部101には、打撃中心線方向の反動が作用するが、上記のように、ハンドル部103を打撃用シリンダ121の中心軸線に近づけることで上記の反動を手で抑え易くなり、操作性が向上することになる。
 以上のように、本実施の形態によれば、コンパクト化され、操作性が向上された使い勝手の良い釘打機100が提供されることとなった。
In addition, according to the present embodiment, the handle portion 103 is moved to the striking cylinder without moving the center of gravity of the airframe with the battery pack 110 attached from the central axis Q (battering center line) of the striking cylinder 121. It becomes possible to approach the central axis of 121. Usually, an operator performs a nail operation by pulling a trigger 103a as a driving operation unit with an index finger while holding the handle portion 103 and applying a forward pressing force to the nailing machine 100. When the driver 125 drives the nail n into the workpiece, the main body 101 is subjected to a reaction in the direction of the hitting center line, but as described above, the handle 103 is brought closer to the center axis of the hitting cylinder 121. This makes it easy to suppress the above reaction by hand, and improves operability.
As described above, according to the present embodiment, it is possible to provide a user-friendly nailer 100 that is compact and has improved operability.
 釘打機100においては、機体の重心位置は、構造的に打撃用シリンダ121の中心軸(打撃中心線)よりも下方にあるが、本実施の形態によれば、上記のように、ハンドル部103を打撃用シリンダ121の中心軸線に近づけて配置できるため、打込み操作部としてのトリガ103aの位置を、機体の重心を通る打込み方向の重心面と同一平面上に配置する構成、あるいは当該重心面よりも上方(打撃用シリンダ121側)に配置する構成とすることが可能となる。その結果、手に作用する釘打込み時の反動が低減され、手による抑え込みがより一層容易となる。なお、重心面とは、重心Gを通り打撃用シリンダ121の中心軸線に平行で、かつ駆動モータ111の回転軸Yと直交する平面をいう。 In the nailing machine 100, the center of gravity of the airframe is structurally lower than the center axis (striking center line) of the striking cylinder 121. According to the present embodiment, as described above, the handle portion 103 can be disposed close to the center axis of the cylinder 121 for hitting, so that the position of the trigger 103a as the driving operation portion is arranged on the same plane as the center of gravity in the driving direction passing through the center of gravity of the airframe, or the center of gravity It becomes possible to set it as the structure arrange | positioned upwards (cylinder 121 for an impact). As a result, the recoil at the time of driving a nail acting on the hand is reduced, and the holding by the hand is further facilitated. The center-of-gravity plane is a plane that passes through the center of gravity G and is parallel to the center axis of the striking cylinder 121 and orthogonal to the rotation axis Y of the drive motor 111.
 なお、上記の実施形態では、圧縮用シリンダ131と打撃用シリンダ121との同軸配置を実現するために、圧縮用シリンダ131を断面ドーナッツ状に形成したが、同軸配置の構成はこれに限られない。例えば、便宜上図示を省略するが、打撃用シリンダ121の後方に圧縮用シリンダ131を同一軸線上に直列状に配置することで実現可能である。
 また、上記の実施形態において、特に圧縮用シリンダ131と打撃用シリンダ121とを直列状に配置する場合においては、圧縮用シリンダをハンドル部103の後方に配置する構成、更には駆動モータ111をハンドル部103の後方に配置する構成に変更してもよい。
 また、上記の実施形態においては、ハンドル部103を圧縮用シリンダ131に連接したが、打撃用シリンダ121に連接してもよい。
In the above embodiment, in order to realize the coaxial arrangement of the compression cylinder 131 and the striking cylinder 121, the compression cylinder 131 is formed in a cross-section donut shape, but the configuration of the coaxial arrangement is not limited to this. . For example, although illustration is omitted for the sake of convenience, this can be realized by arranging the compression cylinder 131 in series on the same axis behind the impact cylinder 121.
In the above embodiment, particularly when the compression cylinder 131 and the striking cylinder 121 are arranged in series, the configuration in which the compression cylinder is arranged behind the handle portion 103, and further the drive motor 111 is handled by the handle. You may change to the structure arrange | positioned at the back of the part 103. FIG.
In the above embodiment, the handle portion 103 is connected to the compression cylinder 131, but may be connected to the striking cylinder 121.
(本発明の第2の実施形態)
 次に本発明の第2の実施形態につき、図3を参照しつつ説明する。図3は釘打機100の上方視での断面図である。本実施の形態は、図3に示すように、複数(本実施の形態では2個)の圧縮用シリンダ131を、当該圧縮用シリンダ131の中心軸Pが打撃用シリンダ121の中心軸Qに対し平行となるように当該打撃用シリンダ121の中心軸Q周りに配置する構成、より好ましくは、2個の圧縮用シリンダ131を、上下方向視において打撃用シリンダ121の中心軸Qを通って延在する垂直面(中心面)に対し左右対称に配置する構成としている。そして、2個の圧縮用シリンダ131の圧縮室131aを連絡通路131bによって互いに連通することで左右一対となすとともに、いずれか一方の圧縮室131aを連通路135によって打撃用シリンダ室121aに連通する構成としている。また、駆動モータ111の回転出力を直線運動に変換して圧縮用ピストン131を直線状に駆動する運動変換機構としてクランク機構115を用いている。上記の構成以外については、前述した第1の実施形態と同様に構成されるため、その説明は省略する。
(Second embodiment of the present invention)
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a cross-sectional view of the nailing machine 100 as viewed from above. In the present embodiment, as shown in FIG. 3, a plurality of (two in this embodiment) compression cylinders 131 are arranged such that the central axis P of the compression cylinder 131 is relative to the central axis Q of the striking cylinder 121. Arranged around the central axis Q of the impact cylinder 121 so as to be parallel, more preferably, two compression cylinders 131 extend through the central axis Q of the impact cylinder 121 when viewed in the vertical direction. It is set as the structure arrange | positioned left-right symmetrically with respect to the vertical plane (center plane) to do. Further, the compression chambers 131a of the two compression cylinders 131 are connected to each other by a communication passage 131b to form a pair of left and right, and one of the compression chambers 131a is connected to the striking cylinder chamber 121a by a communication passage 135. It is said. In addition, a crank mechanism 115 is used as a motion conversion mechanism that converts the rotational output of the drive motor 111 into a linear motion to drive the compression piston 131 linearly. Since the configuration other than the above configuration is the same as that of the first embodiment described above, the description thereof will be omitted.
 本実施の形態によれば、打撃用シリンダ121の中心軸周りに複数の圧縮用シリンダ131を配置したことにより、圧縮装置130による圧縮空気の生成能力を維持しつつ各圧縮用シリンダ131の小径化が可能となり、当該圧縮用シリンダ131に連接されたハンドル部103(図1参照)を打撃用シリンダ121の中心軸Qに近づけて配置できる。とりわけ、打撃用シリンダ121の中心面に対し左右対称に配置したときは、ハンドル部103を打撃用シリンダ121の中心軸Qにより一層近づくことになる。また、打込み操作部としてのトリガ103aの位置を、機体の重心を通る打込み方向の重心面と同一平面上に配置する構成、あるいは当該重心面よりも上方(打撃用シリンダ121側)に配置する構成とすることが可能となる。
 以上のように、本実施の形態によれば、第1の実施形態の場合と同様に、釘打機100の上下方向(図1の左右方向)のコンパクト化が可能となるとともに、釘打ち時の反動を手で抑え易くなり、操作性が向上する。これにより、コンパクト化され、かつ操作性が向上された使い勝手の良い釘打機100が提供される。
According to the present embodiment, by arranging a plurality of compression cylinders 131 around the central axis of the impact cylinder 121, the diameter of each compression cylinder 131 is reduced while maintaining the ability to generate compressed air by the compression device 130. The handle portion 103 (see FIG. 1) connected to the compression cylinder 131 can be disposed close to the central axis Q of the striking cylinder 121. In particular, when arranged symmetrically with respect to the center plane of the striking cylinder 121, the handle portion 103 comes closer to the center axis Q of the striking cylinder 121. In addition, a configuration in which the position of the trigger 103a as the driving operation unit is disposed on the same plane as the center of gravity in the driving direction passing through the center of gravity of the airframe, or a configuration in which the trigger 103a is disposed above the center of gravity (on the impact cylinder 121 side). It becomes possible.
As described above, according to the present embodiment, as in the case of the first embodiment, it is possible to make the nailing machine 100 compact in the vertical direction (left-right direction in FIG. 1) and at the time of nailing. It becomes easy to suppress the recoil of the product by hand, and the operability is improved. As a result, a nailing machine 100 that is compact and has improved operability is provided.
 なお、本実施形態の場合、ハンドル部103は、2個の圧縮用シリンダ131に連接する構成、あるいは圧縮用シリンダ131と打撃用シリンダ121との双方に連接する構成、又は打撃用シリンダ121のみに連接する構成のいずれを採用しても構わない。 In the case of the present embodiment, the handle 103 is connected to the two compression cylinders 131, or connected to both the compression cylinder 131 and the impact cylinder 121, or only to the impact cylinder 121. Any of the connected structures may be adopted.
(本発明の第3の実施形態)
 次に本発明の第3の実施形態につき、図4および図5を参照しつつ説明する。この実施形態は、圧縮用シリンダ131につき、図5に示すように、断面非円形としての楕円形に形成したものである。また、駆動モータ111の回転出力を直線運動に変換して圧縮用ピストン131を駆動するための運動変換機構としてクランク機構115を用いている。この点以外の構成については、前述した第1の実施形態と同様に構成される。このため、同一構成部材については、第1の実施形態で用いた符号を付してその説明を省略あるいは簡略する。なお、クランク機構115は、歯車減速機構113によって減速回転されるクランク軸115aと、クランク軸115aの回転中心から偏心した位置に設けられた偏心ピン115bと、偏心ピン115bに一端が相対回動自在に連接され、他端が圧縮用ピストン133に相対回動自在に連接された連接ロッド115cとによって構成されており、圧縮用シリンダ131の前方領域において、本体ハウジング107の内部に収容されている。
(Third embodiment of the present invention)
Next, a third embodiment of the present invention will be described with reference to FIG. 4 and FIG. In this embodiment, the compression cylinder 131 is formed in an elliptical shape with a non-circular cross section, as shown in FIG. Further, a crank mechanism 115 is used as a motion conversion mechanism for converting the rotational output of the drive motor 111 into a linear motion to drive the compression piston 131. About the structure of those other than this point, it is comprised similarly to 1st Embodiment mentioned above. For this reason, about the same structural member, the code | symbol used in 1st Embodiment is attached | subjected, and the description is abbreviate | omitted or simplified. The crank mechanism 115 has a crank shaft 115a that is decelerated and rotated by the gear reduction mechanism 113, an eccentric pin 115b provided at a position that is eccentric from the rotation center of the crank shaft 115a, and one end that is rotatable relative to the eccentric pin 115b. The other end is connected to the compression piston 133 and is connected to the compression piston 133 so as to be relatively rotatable. The connection rod 115c is housed inside the main body housing 107 in the front region of the compression cylinder 131.
 本実施の形態は、圧縮用シリンダ131の断面形状を上下方向視において打撃用シリンダ121の中心軸Qを通って延在する垂直面(中心面)に対し左右対称の楕円形とすることで、当該圧縮用シリンダ131の中心軸Pを打撃用シリンダ121の中心軸Qに近づけ、ひいてはハンドル部103を打撃用シリンダ121の中心軸Qに近づけている。このため、上述した実施形態の場合と同様に、釘打機100の上下方向のコンパクト化が可能なるとともに、釘打ち時の反動が抑え易くなり、操作性が向上する。これにより、コンパクト化され、かつ操作性が向上された使い勝手の良い釘打機100が提供される。 In the present embodiment, the cross-sectional shape of the compression cylinder 131 is an elliptical shape that is symmetrical with respect to a vertical plane (center plane) extending through the central axis Q of the impact cylinder 121 in the vertical direction. The central axis P of the compression cylinder 131 is brought close to the central axis Q of the striking cylinder 121, and as a result, the handle portion 103 is brought close to the central axis Q of the striking cylinder 121. For this reason, as in the case of the above-described embodiment, the nailing machine 100 can be made compact in the vertical direction, and the recoil during nailing can be easily suppressed, so that the operability is improved. As a result, a nailing machine 100 that is compact and has improved operability is provided.
 なお、本実施例では、非円形形状として楕円の場合を示したが、これに限らず、円形の一部分、つまり円弧状に形成しても構わない。 In this embodiment, the case of an ellipse is shown as the non-circular shape, but the present invention is not limited to this, and it may be formed in a circular part, that is, in an arc shape.
(本発明の第4の実施形態)
 次に本発明の第4の実施形態につき、図6を参照しつつ説明する。この実施形態は、駆動モータ111およびマガジン105を、打撃用シリンダ121に対し傾斜状に配置したものである。図6に示すように、圧縮装置130を駆動する駆動モータ111および歯車減速機構113を収容したモータハウジング109は、上端側(図示左側)が釘打機100の前寄り、下端側が後寄りとなるように傾斜状に配置されており、これにより打撃用シリンダ121の中心軸Qと、駆動モータ111の回転軸Yが傾斜配置とされている。すなわち、ハンドル部103と圧縮用シリンダ131と駆動モータ111は、概ね三角形を成すように配置されている。また、マガジン105は、その長軸線Xが駆動モータ111の回転軸Yに対し平行に配置され、従って、打撃用シリンダ121に対し駆動モータ111と同様に傾斜配置とされている。なお、圧縮用シリンダ131は、当該圧縮用シリンダ131の中心軸Pが打撃用シリンダ121の中心軸Qに対し平行をなすように、打撃用シリンダ121の下方後方寄りに配置されている。また、ハンドル部103は、中心軸Hが打撃用シリンダ121の中心軸Qに対し概ね直交するように配置されている。
(Fourth embodiment of the present invention)
Next, a fourth embodiment of the present invention will be described with reference to FIG. In this embodiment, the drive motor 111 and the magazine 105 are arranged to be inclined with respect to the striking cylinder 121. As shown in FIG. 6, the motor housing 109 that houses the drive motor 111 and the gear reduction mechanism 113 that drives the compression device 130 has an upper end side (left side in the drawing) closer to the front of the nail driver 100 and a lower end side closer to the rear. Thus, the central axis Q of the striking cylinder 121 and the rotational axis Y of the drive motor 111 are inclined. That is, the handle portion 103, the compression cylinder 131, and the drive motor 111 are arranged so as to form a substantially triangular shape. Further, the long axis X of the magazine 105 is arranged parallel to the rotation axis Y of the drive motor 111, and therefore, the magazine 105 is inclined with respect to the striking cylinder 121 in the same manner as the drive motor 111. Note that the compression cylinder 131 is disposed near the lower rear side of the impact cylinder 121 so that the center axis P of the compression cylinder 131 is parallel to the center axis Q of the impact cylinder 121. Further, the handle portion 103 is arranged so that the central axis H is substantially orthogonal to the central axis Q of the striking cylinder 121.
 この実施の形態では、圧縮用ピストン133を直線動作させる運動変換機構としてクランク機構115が用いられている。クランク機構115は、歯車減速機構113によって減速回転されるクランク軸115aと、クランク軸115aの回転中心から偏心した位置に設けられた偏心ピン115bと、偏心ピン115bに一端が相対回動自在に連接され、他端が圧縮用ピストン133に相対回動自在に連接された連接ロッド115cとによって構成されており、圧縮用シリンダ131の前方領域において、本体ハウジング107の内部に収容されている。そして、クランク軸115aが駆動モータ111の回転軸と平行に配置されている。このため、クランク機構115の駆動時において、偏心ピン115bは、クランク軸115aの中心軸回りを回転(公転)する際、圧縮用ピストン133に対し上下方向(図示左右方向)に相対的に変位する。そこで、このような相対的な変位を吸収するべく、本実施の形態では、連接ロッド115cが圧縮用ピストン133および偏心ピン115bに対しそれぞれボールジョイント115dを用いたユニバーサルジョイントによって構成されている。なお、上述した構成以外の構成については、前述した第1の実施形態と概ね同様であるため、同一構成部材については同一符号を付してその説明を省略する。 In this embodiment, the crank mechanism 115 is used as a motion conversion mechanism that linearly moves the compression piston 133. The crank mechanism 115 is connected to a crank shaft 115a that is decelerated and rotated by the gear reduction mechanism 113, an eccentric pin 115b provided at a position eccentric from the rotation center of the crank shaft 115a, and one end of the eccentric pin 115b that is relatively rotatable. The other end is constituted by a connecting rod 115 c that is connected to the compression piston 133 so as to be relatively rotatable, and is housed inside the main body housing 107 in the front region of the compression cylinder 131. The crankshaft 115 a is arranged in parallel with the rotation shaft of the drive motor 111. Therefore, when the crank mechanism 115 is driven, the eccentric pin 115b is relatively displaced in the vertical direction (the horizontal direction in the drawing) with respect to the compression piston 133 when rotating (revolving) around the central axis of the crankshaft 115a. . Therefore, in order to absorb such a relative displacement, in this embodiment, the connecting rod 115c is constituted by a universal joint using a ball joint 115d with respect to the compression piston 133 and the eccentric pin 115b. Since the configuration other than the configuration described above is substantially the same as that of the first embodiment described above, the same components are denoted by the same reference numerals and description thereof is omitted.
 本実施の形態によれば、ハンドル部103の前方に配置された駆動モータ111およびマガジン105を、当該駆動モータ111の回転軸Yとマガジン105の長軸方向を打撃用シリンダ121の中心軸Qに対し傾斜させて配置したものであり、これにより駆動モータ111およびマガジン105の下端側をハンドル部103に近づけて配置することができる。その結果、釘打機100の下部側(図示右側)の前後方向の寸法が縮小され、コンパクト化が可能となる。かくして、コンパクト化による使い勝手が向上された釘打機100が提供される。
 なお、本実施の形態では、駆動モータ111を打撃用シリンダ121の中心軸Qに対し傾斜させて配置するとしたが、圧縮用シリンダ131と駆動モータ111とを置換し、当該圧縮用シリンダ131の中心軸Pを打撃用シリンダ121の中心軸Qに対し傾斜させて配置する構成に変更してもよい。
According to the present embodiment, the drive motor 111 and the magazine 105 arranged in front of the handle portion 103 are arranged such that the rotation axis Y of the drive motor 111 and the long axis direction of the magazine 105 are set to the central axis Q of the impact cylinder 121. Accordingly, the lower end side of the drive motor 111 and the magazine 105 can be arranged close to the handle portion 103. As a result, the size in the front-rear direction on the lower side (right side in the drawing) of the nailing machine 100 is reduced, and a compact design is possible. Thus, the nailing machine 100 with improved usability due to compactness is provided.
In the present embodiment, the drive motor 111 is arranged to be inclined with respect to the central axis Q of the impact cylinder 121. However, the compression cylinder 131 and the drive motor 111 are replaced, and the center of the compression cylinder 131 is replaced.

 次に本発明の第5の実施形態につき、図7~図9を参照して説明する。この実際の形態は、釘打機100を左側又は右側から見た側方視において駆動モータ111の一部とマガジン105の一部が、互いに重なるように配置したものである。本実施の形態では、図7に示すように、マガジン105は、釘打機100の側面視において当該マガジン105の下端部が駆動モータ111を収容するモータハウジング109の下端部に重なるように、圧縮用シリンダ131および打撃用シリンダ121に対し傾斜状に配置されている。これによりマガジン105を駆動モータ111に近づけて配置できる。その結果、釘打機100の下部側(図示右側)の前後方向の寸法が縮小され、コンパクト化が可能となる。かくして、コンパクト化による使い勝手が向上された釘打機100が提供される。
(Fifth embodiment of the present invention)
Next, a fifth embodiment of the present invention will be described with reference to FIGS. In this actual form, a part of the drive motor 111 and a part of the magazine 105 are arranged so as to overlap each other when the nailer 100 is viewed from the left or right side. In the present embodiment, as shown in FIG. 7, the magazine 105 is compressed so that the lower end portion of the magazine 105 overlaps the lower end portion of the motor housing 109 that houses the drive motor 111 in a side view of the nailing machine 100. The cylinders 131 and the striking cylinders 121 are inclined. Thereby, the magazine 105 can be disposed close to the drive motor 111. As a result, the size in the front-rear direction on the lower side (right side in the drawing) of the nailing machine 100 is reduced, and a compact design is possible. Thus, the nailing machine 100 with improved usability due to compactness is provided.
 上記のような配置を可能とするには、マガジン105と駆動モータ111(モータハウジング109)との干渉を回避することが必要である。このため、本実施の形態では、マガジン105と駆動モータ111につき、図8又は図9に示す配置構成とすることで上記の干渉を回避している。図8および図9は、釘打機100を前方から見た正面視における配置構成を例示する模式図である。 To enable the above arrangement, it is necessary to avoid interference between the magazine 105 and the drive motor 111 (motor housing 109). Therefore, in the present embodiment, the above-described interference is avoided by adopting the arrangement configuration shown in FIG. 8 or FIG. 9 for the magazine 105 and the drive motor 111. 8 and 9 are schematic views illustrating an arrangement configuration in a front view of the nailing machine 100 as viewed from the front.
 図8に示す例では、釘打機100の正面視においてマガジン105の長軸線Xに対し駆動モータ111の回転軸Yを傾斜させて配置している。このように配置することで、マガジン105の下端部を駆動モータ111の下端部に干渉することなく重ねて配置することが可能となる。
 また、図9に示す例では、釘打機100の正面視において圧縮用シリンダ131の中心軸Pと打撃用シリンダ121の中心軸Qとを結ぶ直線Zをマガジン105の長軸線Xに対し傾斜させるとともに、駆動モータ111の回転軸Yをマガジン105の長軸線Xに対し平行に配置している。このように配置したときも、マガジン105の下端部を駆動モータ111の下端部に干渉することなく重ねて配置することが可能となる。
In the example shown in FIG. 8, the rotation axis Y of the drive motor 111 is inclined with respect to the long axis X of the magazine 105 in the front view of the nailing machine 100. By arranging in this way, the lower end portion of the magazine 105 can be overlapped without interfering with the lower end portion of the drive motor 111.
In the example shown in FIG. 9, a straight line Z connecting the central axis P of the compression cylinder 131 and the central axis Q of the striking cylinder 121 is inclined with respect to the long axis X of the magazine 105 in the front view of the nailing machine 100. At the same time, the rotation axis Y of the drive motor 111 is arranged parallel to the long axis X of the magazine 105. Even when arranged in this manner, the lower end portion of the magazine 105 can be overlapped without interfering with the lower end portion of the drive motor 111.
 図8および図9には、ハンドル部103の中心軸が符号Hで示される。本実施の形態においては、上記のような配置構成を採用する場合において、バッテリパック110装着状態での釘打機100の機体の重心が、正面視においてハンドル部103の中心軸H上に位置するように、当該ハンドル部103の位置を設定している。これにより、左右の重量バランスの取れた釘打機100が構成されることとなり、操作性が向上する。 8 and 9, the central axis of the handle portion 103 is indicated by the symbol H. In the present embodiment, when the above arrangement is adopted, the center of gravity of the body of the nail driver 100 with the battery pack 110 attached is located on the central axis H of the handle portion 103 in a front view. As described above, the position of the handle portion 103 is set. As a result, the nail driver 100 having a right and left weight balance is configured, and the operability is improved.
 第5の実施形態、特に図9に示した例では、正面視においてマガジン105の長軸線Xと駆動モータ111の回転軸Yを平行に配置できるため、側面視においてもマガジン105の長軸線Xと駆動モータ111の回転軸Yが平行になるように配置させることによって、図7に示す傾斜配置の場合よりも更に重なる領域を広くとることができ、釘打機100のより一層のコンパクト化が可能となる。 In the fifth embodiment, particularly in the example shown in FIG. 9, the long axis X of the magazine 105 and the rotation axis Y of the drive motor 111 can be arranged in parallel when viewed from the front. By arranging the rotation axis Y of the drive motor 111 to be parallel, the overlapping area can be made wider than in the case of the inclined arrangement shown in FIG. 7, and the nailing machine 100 can be made more compact. It becomes.
(本発明の第6の実施形態)
 次に本発明の第6の実施形態につき、図10および図11を参照して説明する。この実施の形態は、ハンドル部103の配置を工夫することによって、釘打ち時の反動を手で抑え易くし、操作性を向上させた変形例である。
(Sixth embodiment of the present invention)
Next, a sixth embodiment of the present invention will be described with reference to FIGS. This embodiment is a modification in which the arrangement of the handle portion 103 is devised so that the reaction during nailing is easily suppressed by hand and the operability is improved.
 なお、釘打機100の全体構成および釘打ち作用については、概ね前述した第1の実施形態と同様であるため、第1の実施形態で用いた符号と同一の符号を付してその説明を省略あるいは簡略にする。また、この実施の形態では、圧縮用ピストン133をクランク機構115によって駆動する構成としているが、クランク機構115の構成については、第3の実施形態の場合と同様であるため、第3の実施形態で用いた符号と同一の符号を付してその説明を省略する。 Note that the overall configuration and nailing action of the nailing machine 100 are generally the same as those of the first embodiment described above, and therefore the same reference numerals as those used in the first embodiment are used for the description. Omitted or simplified. In this embodiment, the compression piston 133 is driven by the crank mechanism 115. However, the configuration of the crank mechanism 115 is the same as that of the third embodiment, and thus the third embodiment. The same reference numerals as those used in FIG.
 この実施形態においては、圧縮用シリンダ131は、打撃用シリンダ121の下方側に配置されている。打撃用シリンダ121と圧縮装置130の圧縮用シリンダ131とは、当該打撃用シリンダ121の中心軸Qと圧縮用シリンダ131の中心軸Pが互いに平行に、かつ中心軸Q,Pを含む面が駆動モータ111の回転軸Yと平行となるように形成されている。 In this embodiment, the compression cylinder 131 is disposed below the striking cylinder 121. The striking cylinder 121 and the compression cylinder 131 of the compression device 130 are driven by a surface in which the central axis Q of the striking cylinder 121 and the central axis P of the compression cylinder 131 are parallel to each other and include the central axes Q and P. It is formed so as to be parallel to the rotation axis Y of the motor 111.
 また、ハンドル部103が本体ハウジング107の後方、すなわち打撃用シリンダ121および圧縮用シリンダ131の後方に配置された構成とされる。ハンドル部103は、打撃用シリンダ121の中心軸Qと交差する上下方向に延在する長尺状のグリップ領域103Aと、当該グリップ領域103Aの上下の各端部から前方に略水平状に延びる連接領域103B,103Cとを有し、上側の連接領域103Bの前端部が打撃用シリンダ121に連接され、下側の連接領域103Cの前端部が圧縮用シリンダ131に連接されている。これにより、ハンドル部103は、打撃用シリンダ121および圧縮用シリンダ131に対し上下2箇所で連接された側面視で略D形に形成されている。 Also, the handle 103 is arranged behind the main body housing 107, that is, behind the impact cylinder 121 and the compression cylinder 131. The handle portion 103 includes a long grip region 103A extending in the vertical direction intersecting the central axis Q of the hitting cylinder 121, and a connecting portion extending substantially horizontally from the upper and lower ends of the grip region 103A to the front. The front end portion of the upper connection region 103B is connected to the striking cylinder 121, and the front end portion of the lower connection region 103C is connected to the compression cylinder 131. Thereby, the handle | steering-wheel part 103 is formed in the substantially D shape by the side view connected with the cylinder 121 for striking and the cylinder 131 for compression at two upper and lower places.
 なお、駆動モータ111に対する通電の遮断、およびメインバルブ137に対する通電とその遮断については、便宜上図示を省略するが、例えば、クランク軸115aの回転角度、あるいは偏心ピン115bの位置等を適宜位置検知センサーによって検知し、当該検知信号に基づき、少なくとも駆動モータ111を制御するべく釘打機100に設けられる制御装置(コントローラ)によって制御されるように構成される。 Although illustration of the interruption of energization to the drive motor 111 and the energization and interruption of the main valve 137 is omitted for the sake of convenience, for example, the rotation angle of the crankshaft 115a or the position of the eccentric pin 115b is appropriately detected by a position detection sensor And a control device (controller) provided in the nail driver 100 so as to control at least the drive motor 111 based on the detection signal.
 さて、本実施の形態では、打撃用シリンダ121の中心軸Qと圧縮用シリンダ131の中心軸Pが互いに平行に配置された構成の釘打機100において、当該打撃用シリンダ121および圧縮用シリンダ131の後方にハンドル部103を配置するとともに、トリガ103aを、打撃用シリンダ121の中心軸線上(ドライバ125の打込み軸線上)と圧縮用シリンダ131の中心軸線上との間に配置する構成としている。図10には、バッテリパック110をハンドル部103に装着した状態での釘打機100の重心位置が符号Gで示される。重心Gは圧縮用シリンダ131の中心軸Pよりも下方(図示右側)にある。 In the present embodiment, in the nail driver 100 having a configuration in which the central axis Q of the impact cylinder 121 and the central axis P of the compression cylinder 131 are arranged in parallel to each other, the impact cylinder 121 and the compression cylinder 131 are concerned. The trigger 103 a is arranged between the center axis of the striking cylinder 121 (on the driving axis of the driver 125) and the center axis of the compression cylinder 131. In FIG. 10, the position of the center of gravity of the nail driver 100 in a state where the battery pack 110 is mounted on the handle portion 103 is indicated by a symbol G. The center of gravity G is below the center axis P of the compression cylinder 131 (on the right side in the figure).
 従って、釘nの打込み作業時において、作業者は、ドライバ125の打込み軸線と、重心Gを通り当該打込み軸線に平行で、かつ駆動モータ111の回転軸Yと直交する平面(以下、重心面という)との間でハンドル部103のグリップ領域103Aを手のひらで前方に押すことができる。このため、釘打ち時の反動が抑え易くなり、操作性が向上する。このように、本実施の形態によれば、操作性が向上された使い勝手の良い釘打機100が提供される。なお、反動が抑え易くなることで、釘nが被加工材から突出した状態となる釘浮き現象を防止することが可能となる。 Therefore, during the driving operation of the nail n, the operator can set the driving axis of the driver 125 and a plane that passes through the center of gravity G and is parallel to the driving axis and is orthogonal to the rotation axis Y of the drive motor 111 (hereinafter referred to as the center of gravity surface). ), The grip area 103A of the handle portion 103 can be pushed forward with the palm of the hand. For this reason, it becomes easy to suppress the reaction at the time of nailing, and the operability is improved. Thus, according to the present embodiment, a user-friendly nailing machine 100 with improved operability is provided. In addition, since it becomes easy to suppress a reaction, it becomes possible to prevent the nail floating phenomenon in which the nail n protrudes from the workpiece.
 また、本実施の形態によれば、ハンドル部103につき、上下方向に延在するグリップ領域103Aの上端が打撃シリンダ121の後端部に連接され、下端が圧縮用シリンダ131後端部に連接された側面視で概ねD形のハンドルとして構成されている。このため、延在方向の一端のみで接合しているタイプのハンドル部に比べ強度の高いハンドル部103が構築される。 Further, according to the present embodiment, with respect to the handle portion 103, the upper end of the grip region 103A extending in the vertical direction is connected to the rear end portion of the striking cylinder 121, and the lower end is connected to the rear end portion of the compression cylinder 131. It is configured as a generally D-shaped handle in a side view. For this reason, the handle | steering-wheel part 103 with high intensity | strength is constructed | assembled compared with the handle | steering-wheel part of the type joined only at the end of the extending direction.
 また、本実施の形態では、ハンドル部103の下端側に装着されたバッテリパック110の下端が、マガジン105の下端よりも上方に位置する構成としている。バッテリパック110は、釘打機100を構成する部材の中でも最大の重さを有する部材であり、本実施の形態では、このような重量物であるバッテリパック110を上方寄り(図示左側)に配置したことで、釘打機100の重心Gをドライバ125の打込み軸線上に近づけることが可能となり、延いては反動による重心Gを中心とするモーメントの低減効果を高める上で有効となる。 Further, in the present embodiment, the lower end of the battery pack 110 attached to the lower end side of the handle portion 103 is configured to be positioned above the lower end of the magazine 105. The battery pack 110 is a member having the maximum weight among the members constituting the nail driver 100. In the present embodiment, the battery pack 110 that is such a heavy object is disposed on the upper side (the left side in the drawing). This makes it possible to bring the center of gravity G of the nail driver 100 closer to the driving axis of the driver 125, which is effective in enhancing the effect of reducing the moment about the center of gravity G due to reaction.
 なお、本実施の形態では、ハンドル部103を打撃シリンダ121および圧縮用シリンダ131の後方に配置する構成において、トリガ103aの位置がドライバ125の打込み軸線上付近となるように設定したが、トリガ103aの位置についてはこれに限定されない。トリガ103aは、例えば、釘打機100重心を通って打撃用シリンダ131の中心軸Qと平行に延在する重心面上、又は当該重心面よりも上方に配置する構成に変更することが可能であるし、又は打撃シリンダ121の中心軸Qと、釘打機100の重心Gを通って打撃用シリンダ131の中心軸Qと平行に延在する重心面との間に配置される構成、更には圧縮用シリンダ131の中心軸Pと打撃用シリンダ121の中心軸Qとの間に配置される構成等に変更しても構わない。上記のような構成においても、従来の釘打機に比べて手に作用する釘打ち時の反動を低減することが可能となる。 In the present embodiment, in the configuration in which the handle portion 103 is arranged behind the striking cylinder 121 and the compression cylinder 131, the position of the trigger 103a is set to be near the driving axis of the driver 125, but the trigger 103a The position of is not limited to this. For example, the trigger 103a can be changed to a configuration in which the trigger 103a is disposed on the center of gravity extending through the center of gravity of the nail driver 100 in parallel with the center axis Q of the impact cylinder 131 or disposed above the center of gravity. Or a configuration arranged between the center axis Q of the striking cylinder 121 and the center of gravity surface extending in parallel with the center axis Q of the striking cylinder 131 through the center of gravity G of the nailing machine 100; You may change into the structure etc. which are arrange | positioned between the central axis P of the cylinder 131 for compression, and the central axis Q of the cylinder 121 for impact. Even in the configuration as described above, it is possible to reduce the reaction at the time of nailing acting on the hand as compared with the conventional nailing machine.
 また、本実施の形態においては、ハンドル部103をシリンダ後方に配置したが、ハンドル部103の配置箇所については、例えばシリンダ胴体部の外面から下方(径方向)に延在する態様で配置してもよく、その場合、トリガ103aが少なくとも釘打機100の重心面上、又は当該重心面よりも上方に配置される構成であればよい。 Further, in the present embodiment, the handle portion 103 is arranged at the rear of the cylinder. However, the arrangement portion of the handle portion 103 is arranged, for example, so as to extend downward (in the radial direction) from the outer surface of the cylinder body portion. In this case, the trigger 103a may be arranged at least on the center of gravity of the nailing machine 100 or above the center of gravity.
 また、本実施の形態では、バッテリパック110をハンドル部103に装着する構成としたが、バッテリパック110については、例えばハンドル部103と駆動モータ111間で、かつ圧縮用シリンダ131の下方の領域に配置してもよい。このような構成によれば、ハンドル部103、駆動モータ111および圧縮用シリンダ131で囲まれる空間を利用しての配置であるため、釘打機100のコンパクト化が図られるとともに、釘打機100の落下時におけるバッテリパック110の保護効果を得ることができる。 In the present embodiment, the battery pack 110 is mounted on the handle portion 103. However, the battery pack 110 is, for example, between the handle portion 103 and the drive motor 111 and in a region below the compression cylinder 131. You may arrange. According to such a configuration, since the space surrounded by the handle portion 103, the drive motor 111, and the compression cylinder 131 is used, the nailing machine 100 can be made compact and the nailing machine 100 can be made compact. The protection effect of the battery pack 110 when the battery is dropped can be obtained.
