Description
本發明係關於一種例如壓縮空氣驅動式之打入工具。 The present invention relates to a driving tool such as a compressed air driven type.
例如用於將釘等打入件1個1個地打入至打入材(木材等)之作業之打入工具係實施用以防止其意外之打入動作(誤作動)之各種對策。下述之專利文獻1中揭示有例如藉由以僅於按照預先設定之正規之順序進行操作之情形時,實施打入動作,且於按照與正規順序不同之錯誤順序進行操作之情形時,不實施打入動作之方式進行之序列機構而防止其誤作動之技術。 For example, the driving tool for driving a nail or the like into one piece of the workpiece (wood, etc.) is subjected to various measures for preventing an accidental opening operation (misoperation). Patent Document 1 listed below discloses, for example, a case where a driving operation is performed only in a case where the operation is performed in a predetermined order, and the operation is performed in an error sequence different from the normal order, A technique for implementing a sequence mechanism in which a driving action is performed to prevent a malfunction.
根據該先前之序列機構,於打入工具之射出口周邊配置接觸臂之前端部,且使另一端側位於使用者利用指尖進行拉動操作之觸發形式之開關操縱桿附近,於打入作業時,先將接觸臂之前端部擠壓於打入材,進行使該另一端側上升之開啟操作,其後於實施開關操縱桿之拉動操作之正規之操作順序中,開關操縱桿之拉動操變為有效,從而實施打入動作。相對於此,於進行接觸臂之開啟操作前,拉動操作開關操縱桿之錯誤之操作順序係構成為即便其後將接觸臂進行開啟操作,先進行之開關操縱桿之拉動操作亦變為無效,從而未能實施打入動作。 According to the prior sequence mechanism, the front end of the contact arm is disposed around the exit opening of the driving tool, and the other end side is located near the switch lever of the triggering mode in which the user uses the fingertip to perform the pulling operation, during the driving operation. First, the front end of the contact arm is pressed against the driving material, and the opening operation of raising the other end side is performed, and then the pulling operation of the switching lever is performed in the normal operation sequence of the pulling operation of the switching lever. In order to be effective, the entry action is implemented. In contrast, before the opening operation of the contact arm, the erroneous operation sequence of pulling the operation switch lever is configured such that even if the contact arm is opened later, the pulling operation of the first switching lever becomes invalid. As a result, the entry action was not implemented.
與上述序列機構不同,對於打入工具,眾所周知有避免匣盒內之打入件排空時之打入動作(空打),防止打入材之劃傷之防空打機構。於下述之專利文獻2揭示有關於如此 之防空打機構之技術。 Unlike the above-described sequence mechanism, it is known for the driving tool to prevent the punching action (slap) when the punching member in the cassette is emptied, and to prevent the scratching mechanism from being scratched. Patent Document 2 listed below discloses that The technology of the anti-aircraft mechanism.

[專利文獻2]日本專利特開2004-255558號公報 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2004-255558
然而,先前之防空打機構係構成為於匣盒內打入件耗盡之情形時、或者成為固定根數以下之情形時,例如上述專利文獻2所揭示,禁止(觸發鎖止)開關操縱桿之拉動操作,或者禁止接觸臂之開啟操作。因此,於防空打機構作動之情形時,易於對開關操縱桿附加較通常大之拉動操作力,或者易於較通常大之擠壓力作用於接觸臂。因此,必需提昇先前開關操縱桿或接觸臂之剛性及支持其之周邊部位之剛性,故使各部位及各構件之壁厚等變厚,因此,其緊湊化較為困難,最終,對於具備上述序列機構之打入工具,未能提供更包括防空打機構者。 However, the conventional air defense mechanism is configured such that when the driving member is exhausted in the cassette or when the number of the driving members is less than or equal to a fixed number, for example, the above-mentioned Patent Document 2 prohibits (trigger lock) the switching lever. Pull the operation, or prohibit the opening operation of the contact arm. Therefore, in the case where the anti-aircrafting mechanism is actuated, it is easy to attach a relatively large pulling operation force to the switch lever, or to easily apply a pressing force to the contact arm more generally. Therefore, it is necessary to increase the rigidity of the front switch lever or the contact arm and to support the rigidity of the peripheral portion thereof, so that the thickness of each part and each member is thickened, and therefore, it is difficult to be compact, and finally, the above sequence is provided. Institutional access tools failed to provide those who included anti-aircraft agencies.
本發明係鑑於相關之先前之問題研製而成者,其目的在於提供一種不僅具備序列機構而且亦具備防空打機構之打入工具。 The present invention has been developed in view of the related problems of the prior art, and an object thereof is to provide a driving tool that not only has a sequence mechanism but also has an anti-aircrafting mechanism.
上述課題係利用下述發明而解決。 The above problems are solved by the following invention.
第1發明係一種打入工具,其除了具備在將接觸臂開啟操作後僅於以進行開關操縱桿之拉動操作之正規順序實施 操作之情形時實施打入動作之序列機構以外,並具備於匣盒內之打入件之餘量達到一定根數以下之情形時,使開關操縱桿之拉動操作無效之防空打機構。 The first invention is a driving tool which is provided in a regular sequence only for performing a pulling operation of the switching lever after the contact arm is opened. In the case of the operation, in addition to the sequence mechanism of the driving operation, and the case where the remaining amount of the driving member in the cassette reaches a certain number or less, the anti-air-sending mechanism that disables the pulling operation of the switch lever is used.
根據第1發明,不僅具備序列機構,而且亦具備防空打機構。防空打機構係構成為並非禁止(觸發鎖止)開關操縱桿之拉動操作,而是使拉動操作無效。因此,不會對該開關操縱桿附加較通常大之(強行之)拉動操作力,故而無需如先前提昇其剛性及支持其之周邊部位之剛性,藉此,實現開關操縱桿及其周邊部位之薄壁化等之緊湊化,從而不僅可緊湊地組裝序列機構,而且可緊湊地組裝防空打機構。 According to the first aspect of the invention, not only the sequence mechanism but also the air defense mechanism is provided. The air defense mechanism is configured not to prohibit (trigger lock) the pulling operation of the switch lever, but to invalidate the pulling operation. Therefore, the relatively large (forced) pulling operation force is not attached to the switch lever, so that the rigidity of the peripheral portion and the peripheral portion thereof are not required to be raised as before, thereby realizing the switch lever and its peripheral portion. The thinning and the like are compact, so that not only the sequence mechanism can be assembled compactly, but also the anti-aircrafting mechanism can be assembled compactly.
第2發明係一種打入工具,其係如第1發明之打入工具,其具備惰輪,其使開關操縱桿可在有效位置與無效位置之間相對變位地設置而切換該拉動操作之有效、無效;且於該惰輪與接觸臂之間,具備惰輪限制構件,其可移動地設置在將惰輪固定於有效位置之限制位置與容許惰輪朝向無效位置變位之非限制位置之間;序列機構係構成為利用正規之操作順序,使惰輪限制構件變位至限制位置,藉由將惰輪固定於有效位置,而使開關操縱桿之拉動操作有效,另一方面,於接觸臂為關閉位置之狀態下,使惰輪限制構件位於非限制位置而容許惰輪朝向無效位置變位,藉此使開關操縱桿之拉動操作無效;且防空打機構具備餘量偵測構件,其在匣盒內之打入件之餘量達到一定根數以下時移動至餘量偵測位置;且該防空打機構構成為由該餘量偵測 構件支持惰輪限制構件,藉由兩者一體地移動至餘量偵測位置而使惰輪限制構件自惰輪與接觸臂之間退避,且藉由容許惰輪朝向無效位置變位而使開關操縱桿之拉動操作無效。 According to a second aspect of the invention, there is provided a driving tool according to the first aspect of the present invention, comprising: an idler gear that allows the switch lever to be relatively displaced between an effective position and an inactive position to switch the pulling operation Effective and ineffective; and between the idler and the contact arm, an idler restricting member movably disposed at a restricted position for fixing the idler to the effective position and an unrestricted position for allowing the idler to be displaced toward the inactive position The sequence mechanism is configured to use a normal operation sequence to displace the idler restricting member to the restricted position, and to fix the idler to the effective position, thereby making the pulling operation of the switch lever effective, and When the contact arm is in the closed position, the idler restricting member is located at the unrestricted position to allow the idler to be displaced toward the inactive position, thereby invalidating the pulling operation of the switch lever; and the anti-airback mechanism has the remaining detecting member. When the remaining amount of the punching member in the cassette reaches a certain number or less, it moves to the remaining amount detecting position; and the air defense mechanism is configured to detect by the remaining amount The member supports the idler restricting member, and the idler restricting member is retracted from between the idler and the contact arm by integrally moving to the remaining amount detecting position, and the switch is made to allow the idler to be displaced toward the ineffective position. The pull operation of the joystick is invalid.
根據第2發明,若匣盒內之打入件之餘量達到一定根數以下,則惰輪限制構件退避至非該限制位置亦非非限制位置之第3位置,且容許惰輪朝向無效位置變位,藉此,使開關操縱桿之拉動操作無效。因此,無論正規之操作順序或錯誤之操作順序,於匣盒內之打入件之餘量達到一定根數以下之情形時,雖然均可實施開關操縱桿之拉動操,但可藉由防空打機構而使該拉動操作無效,從而不實施打入動作。 According to the second aspect of the invention, if the remaining amount of the driving member in the cassette reaches a certain number or less, the idler restricting member is retracted to the third position which is not the restricted position or the non-restricted position, and the idler is allowed to face the invalid position. The displacement is thereby invalidated by the pulling operation of the switch lever. Therefore, regardless of the normal operation sequence or the wrong operation sequence, when the remaining amount of the punching member in the cassette reaches a certain number or less, although the pull operation of the switch lever can be implemented, the air strike can be performed by air defense. The mechanism invalidates the pulling operation, so that the driving action is not performed.
如此般,根據上述防空打機構,即便實施開關操縱桿之拉動操作,亦使該拉動操作無效,從而不實施打入動作,故而觸發鎖止之如先前構成般之強行之拉動操作力不會附加於開關操縱桿,藉此,與先前相比,可實現開關操縱桿及其周邊之緊湊化。 In this way, according to the above-described air defense striking mechanism, even if the pulling operation of the switch lever is performed, the pulling operation is invalidated, and the driving operation is not performed, so that the pulling operation force that is triggered by the previous configuration is not attached. The switch lever is used, whereby the compactness of the switch lever and its periphery can be achieved compared to the prior art.
第3發明係一種打入工具,其係如第2發明之打入工具,其中惰輪限制構件係可轉動地被支持於餘量偵測構件。 The third invention is a driving tool which is the driving tool of the second invention, wherein the idler restricting member is rotatably supported by the remaining amount detecting member.
根據第3發明,若匣盒內之打入件之餘量達到一定根數以下,則餘量偵測機構移動至偵測位置,且惰輪限制構件與該餘量偵測機構一體地退避至第3位置。惰輪限制構件係相對於餘量偵測構件,於限制位置與非限制位置之間可轉動地受到支持。於匣盒內之打入件之餘量大於一定根數 之情形時,餘量偵測構件位於非偵測位置,此時,惰輪限制構件於限制位置與非限制位置之間進行轉動。 According to the third aspect of the invention, if the remaining amount of the driving member in the cassette reaches a certain number or less, the remaining amount detecting mechanism moves to the detecting position, and the idler restricting member and the remaining amount detecting mechanism are integrally retracted to The third position. The idler restricting member is rotatably supported between the restricted position and the unrestricted position with respect to the remaining amount detecting member. The margin of the punch in the box is greater than a certain number In the case of the situation, the remaining amount detecting member is located at the non-detecting position, and at this time, the idler restricting member is rotated between the restricted position and the unrestricted position.
第4發明係一種打入工具,其係如第3發明之打入工具,其中惰輪限制構件係向非限制位置側被賦能。 The fourth invention is a driving tool according to the third aspect of the invention, wherein the idler restricting member is energized toward the unrestricted position side.
根據第4發明,惰輪限制構件係藉由於非限制位置側且容許惰輪朝向無效位置之變位使開關操縱桿之拉動操作無效之側(安全側)被賦能,而確實地防止意外之打入動作。 According to the fourth aspect of the invention, the idler restricting member is energized by the side (safe side) in which the pulling operation of the switch lever is disabled due to the displacement of the idle lever toward the ineffective position, and the accident is prevented. Into the action.
第5發明係一種打入工具,其係如第1~第4發明中之任一發明之打入工具,其中於匣盒中,具備用以調整打入件對於打入材之打入深度之打入深度調整裝置,且該打入深度調整裝置具備抵接於打入材之材抵接臂,且構成為藉由材抵接臂相對於射出口之位置變更而調整打入深度。 According to a fifth aspect of the invention, there is provided a driving tool according to any one of the first to fourth aspects of the present invention, wherein the cartridge is provided with a depth for inserting the punching member into the punching member. The depth adjustment device is driven, and the penetration depth adjustment device includes a material abutting arm that abuts against the driving material, and is configured to adjust the driving depth by changing the position of the material abutting arm with respect to the ejection opening.
根據第5發明,可藉由材抵接臂之位置變更而變更工具本體按下操作時(接觸臂之開啟操作時)打入材與射出口之間隔,從而可調整打入深度。由此,可省略變更接觸臂之長度從而變更打入深度之構成時所需之長度調整機構,藉此,可實現該接觸臂周邊之構成進而開關操縱桿及其周邊部位之緊湊化,從而不僅可緊湊地組裝序列機構,而且可緊湊地組裝防空打機構。 According to the fifth aspect of the invention, the distance between the driving material and the ejection opening can be changed by the position change of the material abutting arm, and the distance between the driving material and the ejection opening can be changed when the tool body is pressed (the opening operation of the contact arm). Thereby, the length adjustment mechanism required for changing the length of the contact arm and changing the configuration of the penetration depth can be omitted, whereby the configuration of the periphery of the contact arm and the compactness of the switch lever and its peripheral portion can be realized, thereby not only The sequence mechanism can be assembled compactly, and the air defense mechanism can be assembled compactly.

本實施形態之打入工具1係於如下方面具有先前所未有之特徵,即,該打入工具1包括序列機構S,其係以僅於按照正規順序進行操作之情形時,在本體部2中實施打入動作;及防空打機構K,其係用以於匣盒4內之打入件n~n之餘量達到一定根數以下時防止本體部2之空打。以下,於兩機構S、K之說明前,對本體部2及觸發閥20之內部結構及其動作進行說明。 The driving tool 1 of the present embodiment has an unprecedented feature that the driving tool 1 includes a sequence mechanism S that is implemented in the body portion 2 only when the operation is performed in a normal order. The driving action; and the air defense mechanism K are used to prevent the body portion 2 from being smashed when the remaining amount of the driving members n to n in the cassette 4 reaches a certain number or less. Hereinafter, the internal structure of the main body 2 and the trigger valve 20 and the operation thereof will be described before the description of the two mechanisms S and K.
如圖3以下所示,於本體部2內置有圓筒形之缸11。於缸11之內部氣密性且可上下移動地內置有活塞12。打入件打擊用之長條打擊錘13設置為自活塞12之下表面中心朝向下方較長地延伸之狀態。該打擊錘13之下端部係進入打入前端部10之打入通路10b內。該打擊錘13若因缸11內之活塞12之下降而下降,則打擊供給至打入通路10b內之1根打入件n之頭部,將其自射出口10a打出。將打出之1根打入件n直接地打入至打入材W。 As shown in FIG. 3 and below, a cylindrical cylinder 11 is built in the main body 2. The piston 12 is built in the airtightness of the cylinder 11 and is movable up and down. The long striking hammer 13 for striking the striking member is disposed in a state of extending long from the center of the lower surface of the piston 12 toward the lower side. The lower end portion of the hammer 13 is inserted into the driving path 10b of the driving front end portion 10.

The rising of the piston 12 is performed by winding the compressed air supplied into the upper chamber 12a of the piston into the lower piston chamber 12b via the return air chamber 11b provided around the cylinder 11, and opening the upper chamber 12a of the piston. Implementation. The switching of the supply of the compressed air to the upper chamber 12a of the piston and the opening of the atmosphere (supply and exhaust) is performed by the opening and closing operation of the above-described trigger valve 20. When the trigger valve 20 is opened, the compressed air is supplied from the pressure accumulation chamber 3b to the upper piston chamber 12a via the supply and exhaust passage 14, so that the piston 12 is lowered to perform the driving operation. When the trigger valve 20 is closed, the upper piston chamber 12a is opened to the atmosphere via the supply and exhaust passage 14 and the exhaust chamber 3c, and the piston 12 is returned to the top dead center.
觸發閥20之開啟關閉動作係藉由開關操縱桿5之拉動操作或拉動操作之解除而實施。觸發閥20係藉由開關操縱桿5之有效拉動操作而開啟,且藉由該拉動操作之解除而關閉。 The opening and closing operation of the trigger valve 20 is performed by the pulling operation of the switch lever 5 or the release of the pulling operation. The trigger valve 20 is opened by the effective pulling operation of the switch lever 5, and is closed by the release of the pulling operation.
圖3係表示本體部2及觸發閥20之初始狀態且該打入工具1之非操作狀態。因此,圖3中,活塞12位於上死點。圖5係表示實施打入動作之時間點之狀態。因此,圖5中活塞12位於下死點。以下,基於圖3及圖5,對本體部2及觸發閥20之動作進行簡單說明。 3 shows the initial state of the main body portion 2 and the trigger valve 20 and the non-operating state of the driving tool 1. Therefore, in Fig. 3, the piston 12 is at the top dead center. Fig. 5 is a view showing a state at which the time of the driving operation is performed. Therefore, the piston 12 in Fig. 5 is located at the bottom dead center. Hereinafter, the operation of the main body unit 2 and the trigger valve 20 will be briefly described based on FIGS. 3 and 5.
首先,於圖3所示之初始狀態且開關操縱桿5未進行拉動操作之狀態(觸發閥20之關閉狀態)下,觸發閥20之閥柄21位於藉由柄簧22而朝向下方突出之關閉位置。在該關閉位置上,作動閥23藉由作用於其下表面之蓄壓室3b之氣壓及柄簧22之賦能力而成為相對閥框體24位於上側之狀態。該狀態成為蓄壓室3b之氣壓經由閥框體24之內周側作用於主 閥25之下表面之狀態。因此,主閥25藉由作用於其下表面之氣壓及閥彈簧26之賦能力而成為相對閥框體24位於上側之大氣開放位置之狀態。主閥25位於該大氣開放位置之狀態成為活塞上室12a被蓄壓室3b遮斷,另一方面經由供排氣通路14連通於排氣室3c之大氣開放狀態。 First, in the initial state shown in FIG. 3 and the state in which the switch lever 5 is not pulled (the closed state of the trigger valve 20), the valve stem 21 of the trigger valve 20 is located to be closed downward by the shank 22 position. In the closed position, the actuating valve 23 is in a state in which the valve body 24 is positioned on the upper side by the air pressure of the pressure accumulating chamber 3b acting on the lower surface thereof and the ability of the shank spring 22. In this state, the air pressure in the pressure accumulation chamber 3b acts on the inner peripheral side of the valve casing 24 to the main The state of the lower surface of the valve 25. Therefore, the main valve 25 is in a state in which the valve body 24 is located at the upper open air position by the air pressure acting on the lower surface thereof and the ability of the valve spring 26. The state in which the main valve 25 is located at the open air position is such that the upper piston chamber 12a is blocked by the pressure accumulation chamber 3b, and the air supply and exhaust passage 14 communicates with the exhaust chamber 3c in an open state.
其次,如圖5所示,若藉由開關操縱桿5之有效拉動操作,閥柄21抵抗柄簧22而向上側被擠壓,則觸發閥20開啟。當閥柄21朝向上側受到擠壓時,作動閥23之下表面側大氣開放,該作動閥23藉由作用於其下部外周面之蓄壓室3b之氣壓而抵抗柄簧22之賦能力,相對閥框體24變位至下側。若作動閥23相對閥框體24變位至下側,則成為主閥25之下表面被蓄壓室3b遮斷,且經由設置於閥框體24之內周側及上部之排氣孔25a連通於排氣室3c之狀態。又,蓄壓室3b之氣壓常時作用於主閥25之下部外周面。因此,若主閥25之下表面側大氣開放,則該主閥25藉由作用於其外周面之蓄壓室3b之氣壓而抵抗閥彈簧26之賦能力變位至下側之空氣供給位置,藉此,該觸發閥20開啟。若觸發閥20開啟,則將壓縮空氣自蓄壓室3b經由供排氣通路14供給至活塞上室12a內。若活塞12藉由供給至活塞上室12a內之壓縮空氣而下降,則如上所述,打擊錘13一體地下降,實施打入。 Next, as shown in Fig. 5, if the valve stem 21 is pressed against the shank 22 by the effective pulling operation of the switch lever 5, the trigger valve 20 is opened. When the valve stem 21 is pressed toward the upper side, the lower side of the actuating valve 23 is open to the atmosphere, and the actuating valve 23 resists the urging force of the shank 22 by the air pressure acting on the accumulator chamber 3b of the lower outer peripheral surface thereof, The valve housing 24 is displaced to the lower side. When the actuation valve 23 is displaced to the lower side with respect to the valve housing 24, the lower surface of the main valve 25 is blocked by the pressure accumulation chamber 3b, and passes through the exhaust hole 25a provided on the inner circumference side and the upper portion of the valve housing body 24. It is connected to the state of the exhaust chamber 3c. Further, the pressure of the pressure accumulation chamber 3b constantly acts on the outer peripheral surface of the lower portion of the main valve 25. Therefore, if the atmosphere on the lower surface side of the main valve 25 is opened, the main valve 25 is displaced against the air supply position of the lower side by the biasing force of the valve spring 26 by the air pressure acting on the outer peripheral surface of the pressure accumulation chamber 3b. Thereby, the trigger valve 20 is opened. When the trigger valve 20 is opened, compressed air is supplied from the accumulator chamber 3b to the upper chamber 12a via the supply and exhaust passage 14. When the piston 12 is lowered by the compressed air supplied into the upper chamber 12a of the piston, the hammer 13 is integrally lowered as described above, and the driving is performed.
若活塞12到達下死點,則活塞上室12a內之壓縮空氣經由設置於缸11之氣孔11a~11a流入回風室11b內。流入回風室11b內之壓縮空氣經由設置於缸11之下部之氣孔11c繞入 至活塞下室12b內,作用於活塞12之下表面。該回風成為用於使活塞12上升之驅動源。 When the piston 12 reaches the bottom dead center, the compressed air in the upper chamber 12a of the piston flows into the return air chamber 11b via the air holes 11a to 11a provided in the cylinder 11. The compressed air flowing into the return air chamber 11b is wound through the air hole 11c provided at the lower portion of the cylinder 11. Into the lower piston chamber 12b, it acts on the lower surface of the piston 12. This return air becomes a drive source for raising the piston 12.
打入結束後,若解除開關操縱桿5之拉動操作,閥柄21藉由柄簧22之賦能力而返回至下側之關閉位置,使得該觸發閥20關閉。若閥柄21返回至關閉位置,則蓄壓室3b之氣壓作用於作動閥23之下表面,使得該作動閥23相對閥框體24上升。若作動閥23上升,則藉由蓄壓室3b之氣壓作用於主閥25之下表面而使該主閥25相對閥框體24上升。若主閥25上升,則成為活塞上室12a及供排氣通路14被蓄壓室3b遮斷,且連通於排氣室3c之狀態。若使活塞上室12a大氣開放,則活塞12藉由繞入至活塞下室12b內之回風而返回至上死點。 After the end of the driving, if the pulling operation of the switch lever 5 is released, the valve handle 21 is returned to the lower closed position by the urging ability of the shank 22, so that the trigger valve 20 is closed. When the valve stem 21 is returned to the closed position, the air pressure of the accumulator chamber 3b acts on the lower surface of the actuating valve 23, so that the actuating valve 23 rises relative to the valve casing 24. When the actuating valve 23 is raised, the main valve 25 is raised relative to the valve casing 24 by the air pressure of the accumulator chamber 3b acting on the lower surface of the main valve 25. When the main valve 25 is raised, the piston upper chamber 12a and the supply and exhaust passage 14 are blocked by the pressure accumulation chamber 3b and communicate with the discharge chamber 3c. When the upper chamber 12a of the piston is opened to the atmosphere, the piston 12 returns to the top dead center by the return air that is wound into the lower chamber 12b of the piston.
如以上說明,觸發閥20藉由開關操縱桿5之有效拉動操作而開啟,藉此,於本體部2中實施打入動作。打入後,若解除開關操縱桿5之拉動操作,則觸發閥20關閉,使本體部2返回至初始狀態。該本體部2之打入動作係僅於利用以下說明之序列機構S,按照正規之操作順序操作開關操縱桿5及接觸臂6之情形時實施。 As described above, the trigger valve 20 is opened by the effective pulling operation of the switch lever 5, whereby the driving operation is performed in the body portion 2. After the driving, if the pulling operation of the switch lever 5 is released, the trigger valve 20 is closed to return the main body portion 2 to the initial state. The driving operation of the main body portion 2 is performed only when the switching lever 5 and the contact arm 6 are operated in the normal operation sequence by the sequence mechanism S described below.
開關操縱桿5係經由支軸5a,可上下傾動操作地由設置於觸發閥20之下方且本體部2之側部之機構底座部16支持。於開關操縱桿5之背面(上表面),支持著惰輪9。該惰輪9係經由支軸9a,可上下傾動地受到支持,且具有在相對於開關操縱桿5之有效位置與無效位置之間進行相對變位,切換該開關操縱桿5之拉動操作之有效、無效之功 能。該惰輪9係藉由省略圖示之扭轉彈簧,而於將其轉動前端部擠壓於閥柄21之方向(圖3為順時針方向之有效位置側)被賦能。惰輪9之轉動前端部係藉由朝向該有效位置側之賦能力而成為常時抵接於閥柄21之狀態。又,開關操縱桿5藉由惰輪9之朝向有效位置側之賦能力之反作用力而朝向各圖中為下側之關閉位置側被賦能。 The switch lever 5 is supported by the mechanism base portion 16 provided below the trigger valve 20 and on the side of the body portion 2 via the support shaft 5a so as to be tiltable up and down. The idler 9 is supported on the back (upper surface) of the switch lever 5. The idler 9 is supported by the support shaft 9a so as to be tiltable up and down, and has a relative displacement between the effective position and the inactive position with respect to the switch lever 5, and the pull operation of switching the switch lever 5 is effective. Invalid work can. The idler pulley 9 is energized by a torsion spring (not shown) in a direction in which the rotational distal end portion is pressed against the valve stem 21 (the effective position side in the clockwise direction in Fig. 3). The rotating tip end portion of the idler pulley 9 is in a state of constantly abutting against the valve stem 21 by the ability to be applied toward the effective position side. Further, the switch lever 5 is energized toward the closed position side on the lower side in the respective drawings by the reaction force of the biasing force of the idler gear 9 toward the effective position side.
若以惰輪9保持於有效位置之狀態進行開關操縱桿5之拉動操作,則藉由伴隨該拉動操作之惰輪9之朝向上方之變位而將觸發閥20之閥柄21朝向上方擠壓。若解除開關操縱桿5之拉動操作,則藉由附加於閥柄21之柄簧22之賦能力而使該開關操縱桿5及惰輪9返回至下側之初始位置(關閉位置)。 If the pulling operation of the switch lever 5 is performed while the idler 9 is held in the effective position, the valve stem 21 of the trigger valve 20 is pressed upward by the upward displacement of the idler 9 accompanying the pulling operation. . When the pulling operation of the switch lever 5 is released, the switch lever 5 and the idler 9 are returned to the initial position (closed position) of the lower side by the ability of the shank 22 attached to the shank 21.
於開關操縱桿5之轉動基部附近設置有以圓柱體形狀之鎖銷15為主體之觸發鎖止機構。於鎖銷15,設置有在其徑向上切口而形成之操作凹部15a。藉由將圖1所示之鎖止桿18進行傾動操作,使該鎖銷15轉動固定角度而成為使操作凹部15a朝向下方之狀態時,成為開關操縱桿5之端部進入該操作凹部15a內從而容許該拉動操作之解鎖狀態。若將鎖桿18傾動操作至鎖止位置,將鎖銷15之操作凹部15a切換成朝向上方之狀態,則成為開關操縱桿5之端部干擾該鎖銷15,使得該拉動操作本身被禁止之觸發鎖止狀態。圖中,皆以解鎖狀態表示,且以下之說明亦以該觸發鎖止機構為解鎖狀態作為前提。 A trigger lock mechanism mainly composed of a cylindrical pin 15 is provided in the vicinity of the rotating base of the switch lever 5. The lock pin 15 is provided with an operation recess 15a formed by slitting in the radial direction thereof. When the lock lever 18 shown in FIG. 1 is tilted and the lock pin 15 is rotated by a fixed angle to bring the operation recess 15a downward, the end portion of the switch lever 5 enters the operation recess 15a. Thereby the unlocked state of the pulling operation is allowed. When the lock lever 18 is tilted to the lock position, and the operation recess 15a of the lock pin 15 is switched to the upward state, the end portion of the switch lever 5 interferes with the lock pin 15, so that the pull operation itself is prohibited. Trigger lock status. In the figure, both are shown in an unlocked state, and the following description also assumes that the trigger locking mechanism is in an unlocked state.
接觸臂6係具有用以防止意外之打入動作之功能者,故 橫跨自開關操縱桿5之轉動基部附近至射出口10a附近之範圍而配置。如上所述,接觸臂6之前端部6a係自打入前端部10之前端突出。接觸臂6之上端部(作動部6b)係於相對機構底座部16可上下變位地受到支持之狀態下,到達開關操縱桿5之轉動基部附近。接觸臂6係作為其整體可上下變位地受到支持。如圖3以下所示,接觸臂6藉由介裝於與打入前端部10之間之壓縮彈簧17而使其前端部6a於自打入前端部10之前端突出之方向上被賦能。 The contact arm 6 has a function for preventing an accidental driving action, so It is disposed across the range from the vicinity of the rotating base of the switch lever 5 to the vicinity of the ejection opening 10a. As described above, the front end portion 6a of the contact arm 6 protrudes from the front end of the front end portion 10 when it is driven. The upper end portion (actuating portion 6b) of the contact arm 6 is brought to the vicinity of the rotating base portion of the switch lever 5 in a state where the opposing mechanism base portion 16 is supported up and down. The contact arm 6 is supported as a whole in which it can be displaced up and down. As shown in FIG. 3 and below, the contact arm 6 is energized in a direction in which the front end portion 6a protrudes from the front end of the front end portion 10 by being fitted to the compression spring 17 that is inserted between the front end portion 10.
於打入操作時,將該打入工具1以將其打入前端部10之前端抵接於打入材W之狀態進行按下操作,藉此,成為接觸臂6之前端部6a相對打入前端部10未上升突出之狀態,藉此,接觸臂6之整體相對打入前端部10上升。若接觸臂6上升,則其上端之作動部6b朝向上方變位。 At the time of the driving operation, the driving tool 1 is pressed in a state in which the front end portion 10 is brought into contact with the driving material W, whereby the front end portion 6a of the contact arm 6 is relatively driven. The front end portion 10 is not raised and protruded, whereby the entire contact arm 6 is raised relative to the driving front end portion 10. When the contact arm 6 rises, the upper end of the actuating portion 6b is displaced upward.
於接觸臂6之作動部6b與惰輪9之間,配置有惰輪限制構件30。該惰輪限制構件30係經由支軸31可轉動地由作動滑塊32支持。該惰輪限制構件30係於圖3所示之非限制位置與圖4所示之限制位置之間可移動地設置。惰輪限制構件30係藉由介裝於與作動滑塊32之間之壓縮彈簧34而於使設置於其上部之鉤型之限制臂部30a變位至接觸臂6之作動部6b側之方向上(圖3以下為逆時針方向之非限制位置側)上被賦能。 An idler restricting member 30 is disposed between the actuating portion 6b of the contact arm 6 and the idler pulley 9. The idler restricting member 30 is rotatably supported by the actuating slider 32 via the support shaft 31. The idler restricting member 30 is movably disposed between the unrestricted position shown in FIG. 3 and the restricted position shown in FIG. The idler restricting member 30 is configured to displace the hook-type restricting arm portion 30a provided at the upper portion thereof to the side of the actuating portion 6b of the contact arm 6 by a compression spring 34 interposed between the actuating slider 32. (Figure 3 below is the counter-clockwise unrestricted position side) is energized.
作動滑塊32係相對於機構底座部16可上下滑動地受到支持。該作動滑塊32係藉由介裝於與機構底座部16之間之壓縮彈簧33而於朝向上方變位之方向上被賦能。於該作動滑 塊32之下部,一體地設置有餘量偵測構件35。該餘量偵測構件35係向下方延伸,且進入設置於匣盒4之上表面之偵測窗4d內。該餘量偵測構件35係構成具有偵測匣盒4內之打入件n~n之餘量是否達到一定根數以下且防止本體部2之空打動作之功能之防空打機構K。該防空打機構K之詳情隨後描述。 The actuating slider 32 is slidably supported up and down with respect to the mechanism base portion 16. The actuating slider 32 is energized in a direction in which it is displaced upward by a compression spring 33 interposed between the mechanism base portion 16. At this action Below the block 32, a margin detecting member 35 is integrally provided. The remaining amount detecting member 35 extends downward and enters the detecting window 4d provided on the upper surface of the cassette 4. The remaining amount detecting member 35 constitutes a runaway mechanism K having a function of detecting whether or not the remaining amount of the punching members n to n in the cassette 4 reaches a certain number or less and prevents the free movement of the main body portion 2. Details of the runaway mechanism K are described later.
序列機構S係包含開關操縱桿5、接觸臂6、及惰輪限制構件30。圖3~圖5係表示於將打入深度調整裝置8之打入深度調整為最大之狀態下按照正規之順序進行操作,實施本體部2之打入動作之情形。圖6~圖8係表示於將打入深度調整裝置8之打入深度調整為最小之狀態下,同樣按照正規之順序進行操作,實施本體部2之打入動作之情形。前者與後者係打入深度之調整狀態不同,而相同之處在於藉由按照正規之順序進行操作而實施打入動作,故綜合兩者進行說明。又,兩者皆於匣盒4內裝填有超過一定根數之根數之打入工具n~n,其餘量充分,且後述之防空打機構K為未作動之狀態之方面亦為相同。 The sequence mechanism S includes a switch lever 5, a contact arm 6, and an idler restricting member 30. 3 to 5 show a case where the driving operation of the main body unit 2 is performed in a normal order in a state where the driving depth of the driving depth adjusting device 8 is adjusted to the maximum. 6 to 8 show a state in which the driving depth of the driving depth adjusting device 8 is adjusted to the minimum, and the driving operation of the main body unit 2 is performed in the same order. The former is different from the latter in the adjustment state of the depth of entry, and the same is that the driving operation is performed by operating in the normal order, so the two will be described together. In addition, both of the loading tools n to n having a number of roots exceeding the predetermined number are filled in the cassette 4, and the remaining amount is sufficient, and the anti-empty mechanism K to be described later is also in the same state.
圖3及圖6係表示打入工具1之初始狀態(非操作狀態)。於該初始狀態下,接觸臂6之前端部6a自打入前端部10之前端突出。其突出尺寸係如上所述,與打入深度調整裝置8之調整狀態無關地相同。 3 and 6 show the initial state (non-operation state) of the driving tool 1. In this initial state, the front end portion 6a of the contact arm 6 protrudes from the front end of the front end portion 10. The protruding dimension is as described above, and is the same regardless of the adjustment state of the driving depth adjusting device 8.
又,該初始狀態成為惰輪限制構件30位於藉由壓縮彈簧34而使該限制臂部30a位於接觸臂6之作動部6b之上方之非限制位置之狀態。 Further, in the initial state, the idler restricting member 30 is in a state in which the restricting arm portion 30a is positioned at an unrestricted position above the actuating portion 6b of the contact arm 6 by the compression spring 34.
惰輪限制構件30係自位於非限制位置之初始狀態起,首先使打入前端部10朝向打入材W,且使接觸臂6之前端部6a抵接於打入材W。於該抵接狀態下,將該打入工具1如圖4及圖7所示地進行按下操作,成為一面將接觸臂6之前端部6a相對地向上方頂起,一面使打入深度調整裝置8之材抵接臂8a抵接於打入材W之狀態。藉由該按下操作,而成為使打入前端部10之前端抵接於打入材W之狀態(圖4),或者,成為使打入前端部10之前端接近打入材W之狀態(圖7),從而實施接觸臂6之整體相對於打入前端部10及本體部2相對上升之開啟操作。該開啟操作係抵抗壓縮彈簧17地實施。 The idler restricting member 30 firstly faces the driving front end portion 10 toward the driving member W from the initial state of the unrestricted position, and causes the front end portion 6a of the contact arm 6 to abut against the driving member W. In the contact state, the driving tool 1 is pressed as shown in FIG. 4 and FIG. 7, and the driving depth is adjusted while the front end portion 6a of the contact arm 6 is relatively raised upward. The material abutting arm 8a of the device 8 abuts against the state of the driven material W. By the pressing operation, the front end of the front end portion 10 is brought into contact with the driving material W (FIG. 4), or the front end of the driving front end portion 10 is brought close to the driving material W ( FIG. 7), thereby implementing an opening operation in which the entirety of the contact arm 6 is relatively raised with respect to the driving front end portion 10 and the main body portion 2. This opening operation is carried out against the compression spring 17.
藉由接觸臂6之開啟操作,其上部之作動部6b朝向上方變位。接觸臂6之開啟操作而朝向該上方之變位量(行程量)係因打入深度調整裝置8之調整狀態而不同,打入深度越大則該變位量越大。其情形於圖4及圖7中明確地表示有作動部6b相對機構底座部16之相對位置不同。 By the opening operation of the contact arm 6, the upper movable portion 6b is displaced upward. The amount of displacement (stroke amount) toward the upper side of the opening operation of the contact arm 6 differs depending on the adjustment state of the depth adjustment device 8, and the larger the penetration depth is, the larger the displacement amount is. The case is clearly shown in FIGS. 4 and 7 in that the relative positions of the actuating portion 6b with respect to the mechanism base portion 16 are different.
如圖4及圖7所示,若藉由接觸臂6之開啟操作而使該作動部6b向上方變位,則惰輪限制構件30之限制臂部30a會被向上方推壓,於是該惰輪限制構件30抵抗壓彈簧34而於圖示順時針方向(限制位置側)上轉動。若惰輪限制構件30在惰輪限制方向上轉動,則如圖所示,成為其前端部抵接於惰輪9之轉動前端側之背面(下表面)之惰輪限制狀態。在該惰輪限制狀態下,成為惰輪9被保持在有效位置且朝向無效位置側之變位受到限制之狀態。 As shown in FIGS. 4 and 7, when the actuating portion 6b is displaced upward by the opening operation of the contact arm 6, the restricting arm portion 30a of the idler restricting member 30 is pushed upward, and thus the idle The wheel restricting member 30 rotates in the clockwise direction (restricted position side) in the drawing against the pressure spring 34. When the idler restricting member 30 is rotated in the idler restricting direction, as shown in the drawing, the tip end portion abuts against the idler restricting state of the rear surface (lower surface) on the rotational distal end side of the idler pulley 9. In the idler restricting state, the idler 9 is held in the effective position and the displacement toward the ineffective position side is restricted.
又,於匣盒4內殘留有超過一定根數之充分餘量之打入件n~n,故餘量偵測構件35成為抵接於推桿4b之上部而無法進入匣盒4內之狀態,且防空打機構K處於未作動之狀態。因此,成為作動滑塊32乃至惰輪限制構件30無法朝向下方變位之狀態,由此,經由惰輪9而附加之閥柄21之壓入反作用力經由惰輪9而由惰輪限制構件30承受,其結果,惰輪9成為被保持在該有效位置且朝向無效位置側之變位確實地受到限制之狀態。 Further, in the cassette 4, the inserts n to n having a sufficient margin exceeding a certain number are left, so that the remaining amount detecting member 35 comes into contact with the upper portion of the push rod 4b and cannot enter the cassette 4 And the air defense mechanism K is in an unactuated state. Therefore, the actuating slider 32 or the idler restricting member 30 cannot be displaced downward, whereby the press-fitting reaction force of the valve stem 21 attached via the idle gear 9 is controlled by the idler restricting member 30 via the idler gear 9. As a result, the idle gear 9 is in a state of being held at the effective position and the displacement toward the ineffective position side is surely restricted.
如上所述,在惰輪限制構件30於位於限制位置之惰輪限制狀態且防空打機構K不作動之狀態下,若拉動操作開關操縱桿5,則以保持於有效位置之惰輪9為主,轉動基端側(支軸9a側)向上方較大地變位,閥柄21抵抗柄簧22而被壓入上方之開啟位置,藉此使觸發閥20開啟。藉由觸發閥20開啟,而如上所述,在本體部2中實施打入動作。 As described above, in the state in which the idler restricting member 30 is in the idler restricting state at the restricted position and the anti-empty mechanism K is not actuated, if the operating switch lever 5 is pulled, the idler 9 held in the effective position is mainly The rotating base end side (the side of the support shaft 9a) is largely displaced upward, and the valve stem 21 is pressed against the shank 22 to be pressed into the upper open position, whereby the trigger valve 20 is opened. By the trigger valve 20 being opened, the driving operation is performed in the body portion 2 as described above.
如此般,由於匣盒4內之打入件n~n之餘量充分,故於防空打機構K未作動之狀態下,可按照首先開啟操作接觸臂6、其後拉動操作開關操縱桿5之正規操作順序進行打入動作。 In this way, since the remaining amount of the punching member n~n in the cassette 4 is sufficient, in the state in which the air-defense mechanism K is not actuated, the operating contact lever 6 can be opened first, and then the operating switch lever 5 can be pulled. The normal operation sequence performs the typing action.
對此,相反地,在首先將開關操縱桿5進行拉動操作;其後將接觸臂6進行拉動操作之錯誤操作順序下,開關操縱桿5之拉動操作本身變為無效,而不予實施本體部2之打入動作。以該錯誤順序操作之情形時之序列機構S之動作示於圖9及圖10中。初始狀態係與將打入深度調整為最大之圖3所示之狀態相同。 On the contrary, in the erroneous operation sequence in which the switch lever 5 is first pulled, and then the contact arm 6 is pulled, the pull operation of the switch lever 5 itself becomes invalid, and the body portion is not implemented. 2 hits into the action. The operation of the sequence mechanism S in the case of operating in the wrong order is shown in Figs. 9 and 10. The initial state is the same as the state shown in Fig. 3 in which the penetration depth is adjusted to the maximum.
在圖3所示之初始狀態且未將該打入工具1朝向打入材W進行下壓操作之狀態下,如圖9所示,即使先將開關操縱桿5進行拉動操作,惰輪9之轉動前端側亦不會成為藉由惰輪限制構件30而限制其朝向無效位置側變位之狀態,故而,導致該惰輪9相對地受到閥柄21推壓而向無效位置變位。即便將開關操縱桿5向上方進行拉動操作,惰輪9仍會向無效位置變位,故而閥柄21不會被壓入上方之開啟位置,因此觸發閥20不會開啟。 In the initial state shown in FIG. 3 and the driving tool 1 is not subjected to the pressing operation toward the driving material W, as shown in FIG. 9, even if the switching lever 5 is first pulled, the idler 9 is The rotation of the distal end side does not restrict the displacement of the idler pulley 30 toward the ineffective position side. Therefore, the idler pulley 9 is relatively pressed by the valve stem 21 and displaced to the ineffective position. Even if the switch lever 5 is pulled upward, the idler 9 is displaced to the inactive position, so that the valve stem 21 is not pressed into the upper open position, so the trigger valve 20 does not open.
如圖10所示,在將開關操縱桿5進行拉動操作之狀態下,即便其後將該打入工具1下壓操作而將接觸臂6開啟操作,藉由該作動部6b推壓惰輪限制構件30之限制臂部30a,仍會使惰輪限制構件30抵抗壓縮彈簧34而於圖示順時針方向之限制位置側轉動,但在該階段中,由於惰輪9變位至無效位置,故而成為惰輪限制構件30之限制臂部30a僅繞入至惰輪9之上方而未卡合於其背面側之狀態,因此該惰輪9仍保持變位至無效位置之狀態。 As shown in FIG. 10, in a state where the switch lever 5 is pulled, even if the driving tool 1 is pressed downward, the contact arm 6 is opened, and the idler limit is pushed by the actuating portion 6b. The restricting arm portion 30a of the member 30 still causes the idler restricting member 30 to rotate against the compression spring 34 in the clockwise direction of the illustrated position, but in this stage, since the idler 9 is displaced to the inactive position, The restricting arm portion 30a of the idler restricting member 30 is wound only above the idler pulley 9 and is not engaged with the back side thereof, so that the idler pulley 9 remains in the state of being displaced to the ineffective position.
如此般,匣盒4內之打入件n~n之餘量較為充分,故即便防空打機構K不作動之狀態下,按照首先將開關操縱桿5進行拉動操作,其後將接觸臂6進行開啟操作之錯誤順序進行操作,開關操縱桿5之拉動操作亦變為無效,觸發閥20未開啟,因此,不實施打入動作。 In this way, the remaining amount of the punching members n to n in the cassette 4 is relatively sufficient, so that even if the air defense striking mechanism K is not actuated, the switching lever 5 is first pulled, and then the contact arm 6 is performed. When the operation is started in the wrong order, the pulling operation of the switch lever 5 is also invalidated, and the trigger valve 20 is not opened, so the driving action is not performed.
其次,於圖11~圖13,表示於匣盒4內無打入件n時打入動作被禁止之狀態。打入深度調整裝置8係設定為最大深度。圖11所示之初始狀態係除了匣盒4內,打入件n耗盡之 方面外,與圖3所示之初始狀態相同。自圖11所示之初始狀態起,首先如圖12所示,若藉由打入工具1之按下操作而將接觸臂6進行開啟操作,則由該作動部6b推壓惰輪限制構件30之限制臂部30a,該惰輪限制構件30在圖示順時針方向上傾動。如圖所示,由於採用於開關操縱桿5之拉動操作前進行接觸臂6之開啟操作之正規操作順序,故惰輪限制構件30之限制臂部30a抵接於惰輪9之前端側背面,藉此,成為該惰輪9鎖止於其有效位置之狀態。 Next, Fig. 11 to Fig. 13 show a state in which the driving operation is prohibited when the punching member n is not provided in the cassette 4. The driving depth adjustment device 8 is set to the maximum depth. The initial state shown in Fig. 11 is that the punching member n is exhausted except for the cassette 4. The aspect is the same as the initial state shown in FIG. From the initial state shown in Fig. 11, first, as shown in Fig. 12, if the contact arm 6 is opened by the pressing operation of the driving tool 1, the idler restricting member 30 is pushed by the operating portion 6b. The arm portion 30a is restrained, and the idler restricting member 30 is tilted in the clockwise direction as shown. As shown in the figure, since the normal operation sequence of the opening operation of the contact arm 6 is performed before the pulling operation of the switch lever 5, the restricting arm portion 30a of the idler restricting member 30 abuts against the front end side of the idler pulley 9, Thereby, the idler 9 is locked in its effective position.
以此方式將接觸臂6開啟操作後,若將開關操縱桿5進行拉動操作,則以鎖止於有效位置之狀態之惰輪9為主,轉動支持側向上方較大地變位,其結果,對於該惰輪9附加用以將閥柄21擠壓至上方之開啟位置之斥力(主要為柄簧22之賦能力)。然而,由於匣盒4內之打入件n為零(一定根數以下),故餘量偵測構件35成為經由偵測窗4d可進入匣盒4內(下方)之狀態,其結果,惰輪限制構件30成為與作動滑塊32一體地可向下方之第3位置變位之狀態。 When the contact lever 6 is opened in this manner, if the switch lever 5 is pulled, the idler 9 is locked in the effective position, and the rotation support side is largely displaced upward. As a result, A repulsive force (mainly the ability of the shank spring 22) for urging the valve shank 21 to the upper open position is added to the idler pulley 9. However, since the punching member n in the cassette 4 is zero (a certain number or less), the remaining amount detecting member 35 becomes a state in which the detecting window 4d can enter the inside (downward) of the cassette 4, and as a result, the idle The wheel restricting member 30 is in a state of being displaceable integrally with the actuating slider 32 at a third position downward.
由此,若即便惰輪9為藉由惰輪限制構件30而鎖止於有效位置之狀態,亦藉由開關操縱桿5之拉動操作而對惰輪9附加閥柄21之斥力,則如圖13所示,惰輪限制構件30被該斥力相反地推壓至惰輪9之轉動前端部,而與作動滑塊32一體地抵抗壓縮彈簧33,朝向下方之第3位置變位。如此般,惰輪限制構件30向下方之第3位置變位,其結果,惰輪9相對於開關操縱桿5向下方較大地轉動而變位至該無效位置,因此,閥柄21未被擠壓至上方之開啟位置,故觸發 閥20不進行開啟。 Therefore, if the idler 9 is locked in the effective position by the idler restricting member 30, the repulsive force of the valve handle 21 is added to the idler 9 by the pulling operation of the switch lever 5, as shown in the figure. As shown in Fig. 13, the idler restricting member 30 is pressed against the front end portion of the idler pulley 9 by the repulsion force, and is displaced integrally with the actuating slider 32 against the compression spring 33 toward the third position below. In this manner, the idler restricting member 30 is displaced to the lower third position, and as a result, the idler 9 is largely rotated downward with respect to the switch lever 5 to be displaced to the inactive position, and therefore, the valve stem 21 is not squeezed. Press to the upper open position, so trigger Valve 20 is not opened.
即便如此按照正規之順序操作接觸臂6及開關操縱桿5之情形,亦於匣盒4內之打入件n~n之餘量達到固定數量以下之狀態下,防空打機構K進行作動,故惰輪9變位至無效位置,使開關操縱桿5之拉動操作無效,因此,不實施本體部2之打入動作。 Even if the contact arm 6 and the switch lever 5 are operated in the normal order, the air-defense mechanism K is actuated in a state where the remaining amount of the punch n~n in the cassette 4 reaches a fixed number or less. When the idle gear 9 is displaced to the ineffective position, the pulling operation of the switch lever 5 is invalidated, and therefore, the driving operation of the main body portion 2 is not performed.
若自圖13所示之狀態起,解除開關操縱桿5之拉動操作,則閥柄21之擠壓斥力不經由惰輪9附加於惰輪限制構件30,故該惰輪限制構件30與作動滑塊32一體地因壓縮彈簧33而返回至上方,回復至圖12所示之狀態。 If the pulling operation of the switch lever 5 is released from the state shown in Fig. 13, the squeezing force of the valve shank 21 is not attached to the idler restricting member 30 via the idler gear 9, so that the idler restricting member 30 is slidably operated. The block 32 is returned to the upper side integrally by the compression spring 33, and returns to the state shown in FIG.
如以上說明,根據本實施形態之打入工具1,不僅具備僅於按照正規順序操作開關操縱桿5及接觸臂6之情形時實施打入動作之序列機構S,亦具備於匣盒4內之打入件n之餘量達到一定根數以下之狀態下不實施打入動作之防空打機構K。 As described above, the driving tool 1 according to the present embodiment includes not only the sequence mechanism S that performs the driving operation when the switch lever 5 and the contact arm 6 are operated in the normal order, but also the cassette mechanism 4. The air defense mechanism K that does not perform the driving operation in a state where the remaining amount of the punching member n reaches a certain number or less.
例示之防空打機構K成為並非禁止(觸發鎖止)開關操縱桿5之拉動操作,而使該拉動操作無效之構成。因此,不對開關操縱桿5附加較通常大(強行)之拉動操作力,故無需相較先前提昇其剛性及支持其之機構底座部16等之支持剛性,藉此,可實現開關操縱桿5及機構底座部16之薄壁化等緊湊化,藉此,不僅可緊湊地組裝序列機構S,而且可緊湊地組裝防空打機構K。 The illustrated air striking mechanism K is a configuration that does not prohibit (trigger lock) the pulling operation of the switch lever 5, and invalidates the pulling operation. Therefore, the pull operation force of the switch lever 5 is not normally increased, so that the support rigidity of the mechanism base portion 16 and the like which support the rigidity of the switch lever 5 is not required, thereby enabling the switch lever 5 and The thinner wall of the mechanism base portion 16 and the like are compacted, whereby the sequence mechanism S can be assembled not only compactly but also the air defense mechanism K can be assembled compactly.
又,根據例示之打入工具1,構成如下:不論序列機構S之正規操作順序或錯誤操作順序,若在匣盒4內之打入件 n~n之餘量達到一定根數以下之狀態下,將開關操縱桿5進行拉動操作,則惰輪限制構件30藉由退避至既非其限制位置亦非非限制位置之第3位置,而容許惰輪9向無效位置之變位,藉此,開關操縱桿5之拉動操作雖可實施,但藉由防空打機構K而使該拉動操作無效,從而不實施打入動作。 Further, according to the exemplified driving tool 1, the configuration is as follows: regardless of the normal operation sequence of the sequence mechanism S or the erroneous operation sequence, if the driving member is in the cassette 4 When the remaining amount of n~n reaches a certain number or less, the switching lever 5 is pulled, and the idler restricting member 30 is retracted to the third position which is neither the restricted position nor the non-restricted position. The displacement of the idler gear 9 to the ineffective position is allowed, whereby the pulling operation of the switch lever 5 can be performed, but the pulling operation is invalidated by the air defense mechanism K, and the driving operation is not performed.
由此,並未將為防止空打而進行觸發鎖止之如先前構成之強行之拉動操作力附加於開關操縱桿5,藉此,與先前相比,可實現開關操縱桿5及支持其之機構底座部16等之薄壁化,進而實現該等之緊湊化。 Therefore, the forcible operating force as previously configured to trigger the lock to prevent the kick is not attached to the switch lever 5, whereby the switch lever 5 can be realized and supported as compared with the prior art. The thinning of the mechanism base portion 16 or the like further achieves such compactness.
進而,惰輪限制構件30係藉由壓縮彈簧34而向該非限制位置側被賦能且使開關操縱桿5之拉動操作無效之側(安全側),藉此,可確實地防止意外之打入動作。 Further, the idler restricting member 30 is energized to the unrestricted position side by the compression spring 34 and the pulling operation of the switch lever 5 is ineffective (safe side), thereby reliably preventing accidental entry. action.
又,根據例示之打入深度調整裝置8,可構成為無需變更接觸臂6之長度,而變更抵接於打入材W之材抵接臂8a相對射出口10a之位置(打入方向之間隔),藉此,變更本體部2之按下時之射出口10a之位置,從而調整打入深度。因此,藉由打入深度之變更,其結果,變更接觸臂6之行程量(至開啟位置之移動量),但接觸臂6之行程量只要足夠使惰輪限制構件30於限制位置與非限制位置之間進行變位者即可,故而,可省略變更該長度之機構,藉此,可實現該接觸臂6之構成之簡化,進而可實現其周邊構成之緊湊化,於此方面亦可容易地實現防空打機構K之併設。 Further, according to the illustrated penetration depth adjusting device 8, it is possible to change the position of the material abutting arm 8a that is in contact with the driving material W with respect to the ejection opening 10a without changing the length of the contact arm 6 (interval of the driving direction) Thereby, the position of the ejection opening 10a when the main body unit 2 is pressed is changed, and the driving depth is adjusted. Therefore, by changing the depth of penetration, as a result, the stroke amount of the contact arm 6 (the amount of movement to the open position) is changed, but the stroke amount of the contact arm 6 is sufficient for the idler restricting member 30 to be in the restricted position and the unrestricted position. It suffices that the position is displaced between the positions. Therefore, the mechanism for changing the length can be omitted, whereby the configuration of the contact arm 6 can be simplified, and the peripheral structure can be made compact. Realize the integration of the air defense mechanism K.
可對以上說明之實施形態加以各種變更。例如,雖例示 有因使用例示之打入深度調整裝置8,故接觸臂6之前端部6a自初始狀態之打入前端部10之前端突出之突出尺寸固定,且深度調整之結果,變更該行程之構成,但亦可構成為取代上述打入深度調整裝置8,而利用變更接觸臂之長度,調整打入件n之打入深度。 Various changes can be made to the embodiments described above. For example, although exemplified Since the driving depth adjustment device 8 is exemplified, the front end portion 6a of the contact arm 6 is fixed from the initial state of the front end portion of the front end portion 10, and the depth is adjusted, and the stroke is changed. Alternatively, instead of the above-described penetration depth adjusting device 8, the depth of the driving member n may be adjusted by changing the length of the contact arm.
又,就匣盒4之形態而言亦可進行變更,可變更為將多根打入件經由導線並列地暫時結合,且將其以捲繞狀態裝填於圓筒形之匣盒內之形態之匣盒。該情形時,可構成為具有將供給至本體部2之壓縮空氣作為驅動源,與本體部2連動地進行作動之打入件進給爪,且構成為相當於藉由利用另外設置之餘量偵測機構而於打入件之餘量達到一定根數以下之情形時例示之餘量偵測構件35之卡合構件而限制該打入件進給爪之動作,實施防止空打。 Further, the shape of the cassette 4 can be changed, and the plurality of the driving members can be temporarily joined in parallel by the wires, and loaded in a cylindrical state in a cylindrical shape.匣 box. In this case, the driving member feeding claw that moves the compressed air supplied to the main body unit 2 as a driving source and operates in conjunction with the main body unit 2 may be configured to be equivalent to a margin by using another setting. When the remaining amount of the punching member reaches a certain number or less, the engaging member of the remaining amount detecting member 35 is exemplified to restrict the action of the driving member feeding claw, and the air strike prevention is performed.
