Abstract

The invention provides a driven machine. When a down pressing operation is processed to the driven machine mainbody, a contact arm for preventing error action is moved to an opening position, and a handle level processes an latch pulling operation, a triggered valve opens and processes driven action. In the driven machine, an acting force of the triggered valve to close position acts on the contact arm, so down pressure of the mainbody becomes large relatively and operation becomes poor. The driven machine provided by the invention can eliminate the problem. An acting force (14) of a valve rod (11) acts on an action arm (6b) of the contact arm (6) along direction orthogonal with movable direction, and does not become resistance in movable direction, and reduces down pressure.

Description

200909150 IX. Description of the Invention: [Technical Field to Be Invented by the Invention] As a month, a driving machine that operates with compressed air as a .3⁄4 moving source, such as a nailing machine or a screwing machine, is involved. [Prior Art] For example, a gas-driven nailing machine includes a piston and a gas (4) main body portion that is moved back by the compressed air, and a handle portion that is provided in a state of being pulled out from the main body portion, in the main body portion The striker guide for the launch port of the nail (the dri is two big... usually the base portion of the handle portion is provided with the user's finger side and the handle, and the action is to open and close the cylinder on the main body side side: Gger Ve). When the user uses the fingertip to make a == shift and the _ nail that is supplied to the striker guide is hit by the front end of the = needle guide, the contact arm is usually mounted - (10) (4): Is mainly used to prevent the malfunction of the driver

Ul—Sizes from the front end of the striker guide _ position and the open ((10)) ” position-side elastic force applied to the end of the strike. Only in the case;: Guide: Normal, off the push position pushes the contact When the arm 1 is in the open state in which the end portion of the river is opened, the button J of the switch lever is opened (the malfunction preventing mechanism). The reading is effective and the nail is hit against the malfunction preventing mechanism. For example, the following Patent Document No. 2 200909150 adopts a configuration in which the contact arm extends along the striker rail toward the main body side (upper side) such that the upper end portion thereof is located on the back side of the switch lever (trigger valve side). The lower side of the upper end of (idler). According to this configuration, when the contact # is moved up and the upper end portion of the idle lever is pushed and moved toward the trigger valve side (upper side) by the upper end portion thereof, when the switch lever is pulled in this state, the idle lever will be Moving further upwards, the valve stem of the trigger valve moves toward the open position. When the valve stem is pushed into the open position and the trigger valve is opened, compressed air can be supplied to the cylinder of the main body portion to perform the driving operation. On the other hand, in the closed state in which the contact arm is not moved up, the upper end portion of the idle lever is moved laterally toward the trigger valve side (upward) by the upper end portion thereof, so that even the switch lever is pulled in this state. In the operation, the movement of the idler lever is insufficient, and as a result, the amount of movement of the valve stem to the open side is insufficient, and since it is not opened, the driving of the main body portion is not performed, and the following Patent Document 2 discloses the following. The upper end of the contact arm extending to the vicinity of the switch lever is provided with an intermediate spacer. According to this configuration, when the contact arm is replaced with the upper end portion by the upper end portion, the upper portion of the action position side is moved by the intermediate spacer to the valve stem side of the trigger valve. When the pull-out operation is performed, the idle lever enters the field at the main body of the recording door. The cylinder is supplied with compressed air: the action of the gang is different from that of the damper. The partition does not move to the side of the action position [because of the amount of movement of the middle clamp bar; === the lever performs the pull-up operation = thus the amount of movement of the non-rod to the off side between the triggers is not open 4, so the subject is not performed Ministry of the Ministry = move 7 200909150. Patent Document 1: Japanese Patent No. 3670182 Patent Document 2: Japanese Patent No. 2727960. The conventional malfunction prevention mechanism configured as described above has the following problems. The contact arm is relatively moved up relative to the striker rail by the user pushing the hitting machine to the side of the hitting position. In the open state, as described above, the upper end portion of the upper end portion is directly or in the middle of the spacer = the upper end portion of the idle lever is triggered to be decremented, thereby forming a state in which the valve stem (four) is closed. When the trigger is pulled in this state, the idler advances the _ to the open position. The valve stem is biased toward the off position side by the elastic force of the pressure spring or the pressure of the compressed air. Therefore, when the contact arm is moved up, the switch lever is pulled toward the open position side, and the force of the valve stem is strengthened, and the external force acting on the side toward the closed position acts on the contact arm as it is. The external force acts in the direction in which the main body of the driving machine is lifted from the material to be driven (reverse action), so the user needs (4) a correspondingly large amount of force to push the main body of the hitting machine in the driving direction, at this point The operability of the driver is impaired. SUMMARY OF THE INVENTION The present invention has been made to eliminate the conventional problems, and an object thereof is to reduce a switch lever by applying a force that does not cause the valve stem toward the closed position to the contact arm or to greatly reduce it. The operativeness of the driver is improved by the reaction during operation. For the purpose of this, the printers of the configurations described in the respective technical solutions were used. 8 200909150 The drive machine according to the first aspect of the invention is in a state in which the movement of the intermediate member is restricted and the movement of the idler is restricted when the pusher main body pushes the contact arm to the open position. When the large-sized big talk about the pull-bar operation of the switch lever, the 'the idler lever is enough to slam the 4' to trigger the valve stem to overcome the force and is pushed to the open position to the SIS to the open position. When the triggering valve is opened and the main body of the driving machine is thinned 2, the direction of the direction in which the intermediate member moves from the lateral direction to the open position is orthogonal to the moving direction of the contact arm, or obliquely forward s, ρ ι abuts and is held at the position of the motion transmission position (the movement is limited to the movement of the movement), so the force applied to the valve stem of the dual-purpose It by the idler rod does not act as a contact arm. The direction of movement* is also applied thereto, or can be greatly reduced, so that the force acting on the direction of movement of the contact f is dominant, mainly the force exerting the contact arm directly toward the off position side. Side: The orientation of the valve stem applied to the contact arm can be closed in this way; it can be eliminated or greatly reduced, so that the reaction of the main body of the driver can be eliminated or reduced. Thereby, the burden on the spoon can be reduced and the operability of the driver can be improved. According to the driving machine according to the first aspect of the invention, the contact arm is only required to be in a position to restrict the movement of the towel member to the action blocking position: between the unrestricted position and the closed position (off position) That is, the amount of -It is the stroke of the contact arm to ensure that the required movement of the idler is based on _; == compared to 'can be a smaller stroke. Therefore, the configuration of the first one can make the contact arm The required stroke can reduce the stroke of the contact arm up to the open position, that is, the 200909150 ===:=end (emission) is more uniform, and can be constructed according to the technical solution 2 The contact arm enters its limit ^=The intermediate member is rotatably supported, and the shape of the movement path of the arm portion is set. When the contact arm is brought into the limit: _ path is intersected, and the object is more: the transverse direction of the path and the contact (substantially The direction of movement of the contact arm, that is, as described above. Therefore, the following action toward the off position side can be eliminated; the case where the interpole on the intermediate member is applied thereto, from: The force of the external force application side of the movement direction of the movement is suppressed or Row: reaction of the body of the contact arm. Excluding the driver of the opening pull operation [Embodiment] Description: The first table is from the f to the seventh figure, in the embodiment of the present invention, as SLt The intrusion machine involved in the implementation method is provided by the inflating air of the factory of the present embodiment, and the screwing machine can be similarly used for each configuration K. The direction in which the wide shot is made is set to the lower side, and the driver 1 is provided with the urging unit 2, and has a built-in slash σ, a grip portion 3, and a staple cartridge 4. The main body hits the punch (nail) and enters To the piston and the gas rainbow of the 10200909150 in the material. The piston striker is in the striker for hitting the part from the main body 2. The head valve of the 5 5 2 is also used for the suction and exhaust. The main body portion is provided in a well-known middle row. The main body portion 2 is provided with the upper side of the first and second modes, and the upper side is not required to be specially plugged (the upper part of the gas; the head valve is opened when the head valve is opened) The striker will move n, ,, °, and press the air to move the piston down. When the valve is closed, the gas is red. The front end of the Dingli needle guide 5 is played. When the head is opened and closed by the head squat to carry out the air: two 吏 two, return two to the top dead center. The handle part 3 = 1 = ^, she is closed. The grip portion 3: the side portion of the plate 卩2 protrudes laterally, and the compressed air is accumulated in the compressed air supply from the outside through the vent hose 3b. The pressure accumulating chamber in the handle portion 3 3a (with the main body 2;:; the base valve 10 attached to the handle portion 3 is also a compression trigger valve 1 in the handle portion 3. The contact is switched. The fine milk is used as a part of the drive source to straddle the state. : Guide: 5 and: The front end portion of the hand 3 is inserted into the 4: one driving member. The plurality of driving members are supplied one by one in the :T_needle guide 5 through the main body portion.涓 涓 / / / / β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β β The trigger arm of the actuating arm portion 6b is in the upper and lower directions by the support base portion 6b provided on the side portion of the main body portion 2 through the switch urging arm portion 6b provided to face the f-valve valve 10 Slidingly supported.

The state of 6b^^T is set. In the inspection, the direction of the circumference of the needle guide 5 of the flJ-in-the-needle guide 5 is 5 (the til portion 6a is placed so as to be able to guide the striker in the direction of the striker, the direction of the mountain, and the vertical direction in the first figure) Bit = 5: The position where the portion protrudes in a minute size, and the position at which the other end of the needle track 5 is aligned moves. In the middle of the figure, the arm:::: The spring 7 is moved to the off position side (the first-open position. The contact arm 6 phase == the compression spring 7 is moved toward the opposite side by the following operation = guide The driving position P' of the phase-in material W of the open position of the handle 5 is pressed by the user to the main body portion 2 toward the portion (the emission port) to be driven into "the front end of the striker guide 5; the contact arm 6 is closed" Directly exerting force on the position side: The user must at least overcome the force and move the main body 2 into the yellow position of the driving position, and enter the machine! Set as the contact arm. This embodiment involves The lower stroke of the main body portion 2 = the position to be opened to the open position. This point will be described later. The main stroke is smaller than the conventional stroke contact arm 6 having the same prevention, F), which is used to make it unintentional. The operation is performed: (The malfunction prevention main body 2 does not malfunction. Hereinafter, in the case of 1/椁2G, the two lines will be described. The second figure shows the misoperation prevention output. The details of the stop mechanism F are shown below.情 12 200909150 As described above, the trigger valve i is disposed at the base of the handle portion 3, and the trigger is opened on the side. The switch lever 2 is rotatably supported on the side of the main body portion 2 in the lower and lower sides of the main body portion 2. On the side of the auxiliary support shaft 21, the support shaft 23 can be rotated up and down to support the back idle The rod 22 is bored by a torsion spring H that is interposed around the fulcrum 23. The direction of the cymbal (clockwise in the figure) is applied: the valve stem 11 of the H-trigger valve is constantly abutted against the idler rod 22 In the upper state, the trigger valve abuts the valve stem 11 that is urged toward the protruding side as described later by the torsion spring 24 by the torsion spring 24 to the clockwise side of the figure. This can indirectly switch the switch (4) clockwise to the figure (off. As shown in the second figure, the switch lever 2〇 is closed (Fig. I = ten: 转动 rotational end position)' due to the switch lever 20 The stopper portion 2〇a. The lower surface of the support port 42a (the right side in the drawing) abuts and is restricted.

The trigger valve 10 is a conventionally known configuration, and is modified in the present embodiment, and will be briefly described below. The valve that is wide and has a rod shape is dry, and the first valve body 12 and the second valve body 13 are provided. The valve body 12 is fixed to the base of the handle portion 3. The second valve body a is supported by the second figure of the -12th portion without moving up and down. The valve stem is supported in a state between the first valve body 12 and the second valve body 13 and is movable along the line = direction (upward and downward directions in the drawing). In the contraction, the cup U is applied to the side of the side of the side that is protruded downward from the first valve body 12 by the pressing plate 14 interposed between the rear end portion and the second valve body 13 force. Further, a U-hole 13as is provided in the rear portion of the second valve body 13. Through the vent hole 13a and the exhaust passage 3e, the second valve body and the valve stem upper chamber 16 (the space portion around the compression spring 14) are always 13 200909150 when the pull-out operation of the switch lever 20 is transmitted to the position side. The elastic force is applied to the opening of the 'first-sealing ring mountain'-the valve body 12 shape=the first between the fourth figure 12 and the second valve body 13 is opened to the lower side of the valve body 13 to the atmosphere. On the other hand, in the second portion: the valve body is actuated by the supply port 3c via the air supply port 3c; and when the first pressure changing chamber 15 is opened to the atmosphere, the second is performed. Therefore, : is shown in the fourth figure. When the second intermediate body shifting = 18 is interrupted by the seal ring 13b and the pressure accumulating chamber % side, [to, the inner peripheral surface of the first valve body 12 is separated from the inner peripheral surface of the first valve body 12, and is communicated via the exhaust ring. When the second pressure changing chamber 18 is opened to the atmosphere, the upper surface of the head valve of the main body portion 2 is opened to the atmosphere. This phase ^ oxygen: = the lower side of the regular role has run 3a hollow when open, the head squat up and return to the room = hit the sweat into the field 31 upper chamber open and flow into the compressed air 'piston down and when When the valve stem 11 returns to the closed position by the force, the first pressure changing chamber is connected to the first to second largest 15 and the pressure chamber 3e is in communication, and the contracted air flows in and flows into the first pressure changing chamber 15 The air acts on the body; and the second step 苐 k k pressure chamber 18 is intercepted by the seal ring 13c, and the 4 pressure chamber 18 supplies compressed air. When the upper side is fΊ', it passes through the suction and exhaust passage 3 (H乍 is used for the head valve, and the second fine air acts on the upper side of the head valve), the head valve is closed, and the upper chamber is opened to the atmosphere, thereby Returning the piston to the top dead center. Thus, by moving the valve stem 11 to the open position and the closed position, the second 阙14 200909150 body 13 moves up and down', thereby changing the second variator 18 to the head _ upper (four) The open state of the atmosphere = the state of the gas. The movement of the profit-shrinking to the open position and the closed position is 2 = through the switch lever. The opening operation of the switch lever 2Q is by the user with the finger ==: Pull operation (rotation in the counterclockwise direction of the figure, in addition, in the switch lever 2 〇 relative to the main body portion 2 == °3 has 2;; _:, the extension of 6 6b#] ^ # 〇; ^ part 31 The length is appropriately set. = The length of 1 is broken by 5 and the length is the following, that is, if the f 3 = in the closing position, the value of the operating arm 6b is on the side; the side: from 7. the seat 2a (five) In the state where the amount of protrusion is small, this is not the case, and as shown by the solid line in the third figure, the contact arm; = is moved up so that the action arm portion 6b is located on the upper side. The length of the action arm portion 6b_a portion is abutted (overlapped), and the upper end of the action arm portion 6b at the closed position is traversed by the restriction arm 31 of the double-pointed gas-two intermediate member 30 from the lateral direction (large It is not in contact with the operating arm portion 6b of the contact arm 6, but is limited to the rotation of the operation blocking position side, thereby making the intermediate member = 3 传递 as the transmission position.

Thus, the contact position between the closed position and the open position of the contact arm 6 is set to a size sufficient to move the arm portion 6b relative to the left side of the movement path of the restricting arm portion 31 toward the closed position side of the member 30. "Advance and retreat" is thus a position that restricts the intermediate structure = the middle side of the turning motion (the middle line indicates the position at which the position allows the turning operation (the position in the third figure), and the size moved between them. Compared with the configuration of the part of the total movement amount of the idle lever, the actual compensation, the amount of movement of the contact arm 6 is as small as possible. In the machine 1, the shape of the composition. Ben f

The configuration in which the amount of movement of the idle lever 22 does not contribute. The amount of movement of ', , , ' on the other hand extends to the front end of the death/day, ▼, 22 in the second figure. Hereinafter, the length of the holding arm portion 32 is 32 toward the idle lever, and the length of the holding arm portion 32 is two, for example, the arm portion 32. (Whether it is the motion transmission position, the movement is considered to be the length dimension of the constant end contact as shown in the figure. The pass/break position is maintained at a certain position with the front end portion of the idler lever 22. The temple arm portion 32 urges the front intermediate member 30 of the idler lever 22 in the counterclockwise direction (the torsion spring 33 around the holding arm λ vehicle 21) by the urging. The intermediate member is 3 〇. The position of the 卩32 is shifted to the upper side in the figure.) The second end of the figure is rotated in the counterclockwise direction (the pedestal portion 2a is restricted.) This restricts the arm portion 31 from abutting on the support. In a state in which the holding arm portion 32 of the intermediate member 30 is constantly pressed by the torsion spring 33, the tip end of the idle lever 22 is forced from the lower side by the erroneous operation preventing trigger valve 1Q and the main body portion 2 stopping mechanism F. It can be used as shown below (normally malfunctioning. First, the first machine and the action of the driver 1). The first chart should not be driven into the machine! Brother and the law prevent the mechanism F In the initial state, the arm portion 6b is in a state in which the arm portion 6b is in the closed position with respect to the contact / 6 so that the movement thereof is small. (In addition, the two seat portions 2a are lowered downward to protrude the size portion 2Qa and support The pedestal $ * 8 cup 20 is not subjected to the pulling operation, and the side of the block valve 10 abuts and remains in the closed position. Trigger = off ===_ protruding side, set, the _ (four) is ^ C head room Closed state. Guide rail: Front: State starts to enter operation First, the boring needle is pressed down, and when the sub-body portion 2 is brought into the state as it is, the action 璧^contact #6 relatively moves up the stroke L and the opening amount becomes larger. The portion 6 is moved upward relative to the support pedestal portion 2a, and is suddenly moved upward to be in an open shape in the third view. As shown, when the amount of protrusion of the contact arm 62a is increased by two, thereby causing the arm rib to be moved from The support pedestal portion restricting arm portion 31 is moved to the middle of the intermediate member 30, and the intermediate member 30 is fixed to the action 30; In the state, the intermediate member is fixed to the movement: the member 3 is rotated clockwise in the figure to restrict the displacement to the position where the front end portion of the idler lever 22 is downward ( In the compression stage 5, the idler rod 22 of the valve stem 11 facing the off position side acts as the elastic force of the _4 and the air pressure of the upper chamber 16 of the valve stem, and the external force does not apply the external force in the clockwise direction to the intermediate member. The pressing force 1 arm portion 31 pushed by the portion 6b acts from the side direction of the moving direction of the operating arm 6 of the arm 6 to act. Since the pressing force P is in a direction _ which is substantially orthogonal to the slight frictional resistance from the contact arm, it is not hindered from restricting the movement thereof. The urging force of the intermediate rod 11 toward the off position side (the main 17 200909150 is the urging force of the compression spring 14) does not act as a force for moving the contact arm 6 toward the off position side, so the user only needs to The main body portion 2 can be pressed down by the compression spring 7 that biases the contact arm 6 directly toward the closed position side, so that the main body portion 2 can be depressed with a smaller force than in the related art. In the state in which the main body portion 2 is pressed down by a force smaller than the conventional one (the state in which the contact arm 6 is moved to the open position, the rotation restricting state of the intermediate member 30) is used as shown in the fourth figure. When the switch lever 20 is pulled up and pulled upward in the drawing, the idle lever 22 substantially displaces the rotation support side (the side of the support shaft 23) upward without substantially displacing the front end portion thereof, thereby largely shifting upward as a whole. By the pulling operation of the switch lever 20, the idle lever 22 is largely displaced upward, and the valve stem 11 is moved upward by a sufficient stroke to disengage the first seal ring 11a from the first valve body 12, thereby making the first The pressure change chamber 15 is opened to the atmosphere, and the second valve body 13 is moved downward, whereby the second pressure change chamber 18 is opened to the atmosphere, and the trigger valve 10 is opened, thereby opening the head valve in the main body portion 2 Into the action. When the user releases the pulling operation of the switch lever 20 after the end of the driving operation, the switch lever 20 returns to the closed position by the elastic force of the valve stem 11 toward the off position side, so that the valve stem 11 also returns to the closed position. The trigger valve 10 is closed. When the trigger valve 10 is closed, the first seal ring 11a of the valve stem 11 is hermetically fitted to the inner peripheral side of the first valve body 12, and the first pressure change chamber 15 is cut off from the atmosphere, and additionally from the pressure accumulating chamber 3a. Compressed air is supplied into the first pressure changing chamber 15. When the compressed air is supplied to the first pressure changing chamber 15, the second valve body 13 moves up and supplies compressed air to the second pressure changing chamber 18, thereby moving the head valve downward in the main body portion 2 to store the upper chamber of the cylinder. The pressure chamber 3a is cut off and opened to the atmosphere, thereby returning the piston to the top dead center. Thus, a series of driving operations of 18 200909150 in the main body 2 ends. After the lower hitting action is completed, the user releases the two of the main body portion 2 (upwardly upward), thereby causing the contact arm 6 to return to the detecting arm portion 6δ by using the == two to the closed position; The 轨 of the rail 5 is in a state of being protruded by a size L. On the other hand, in the case of the above-mentioned process, the upper end of the second = arm 6 of the lower pressing operation of the main limb 2 is performed before the kicking action is performed. The intermediate structure is divided into two, and the result is that the tree state is decomposed, and the occupant has a force acting toward the closed position on the mast 22 (mainly the hoist: the force acts as an indirect direction to the intermediate member 3) The figure shows the external force, ==? external force, , ; μ factor, the result is that when the arm is made by the action arm, the intermediate member 30 overcomes the twist 33 and the figure: == reaches the action resistance The position is broken so as to be displaced by the idler lever 22, so that the mast u return is not completely - so that u is moved downwards to the second valve body gas, so that in the main body portion 2 two places =: ::Large:: The compressed air is supplied to the upper chamber to stop the piston; in the lower point: in the state where the operation of the open mast 20 is still held, 19 200909150, the main body 2 is directed toward the other. The position is depressed, so that even if the contact arm 6 is moved up, the action arm portion 6b is supported from the support base portion 2 as shown in FIG. In a, the stroke L is protruded, and the intermediate member 30 is still held at the action blocking position, so that the amount of movement of the idler lever 22 is insufficient, and the trigger valve 10 is maintained in the closed state. Due to this, the so-called continuous strike can be prevented (in While the switch lever is being pulled, the plurality of parts are continuously driven in. In this case, when the pull-out operation of the switch lever 20 is released, the valve stem 11 is completely returned to the closed position, and the seal is sealed. The ring lib is separated from the second valve body 13 to supply compressed air to the first pressure changing chamber 15, whereby the second valve body 13 is moved upward to supply compressed air to the second pressure changing chamber 18, and as a result, the head valve is in the main body portion 2 When closed, the upper chamber of the cylinder is opened to the atmosphere, so that the piston returns to the top dead center, and a series of driving operations in the main body portion 2 is ended by the above operation. Further, when the pulling operation of the switch lever 20 is released, the idle lever 22 is The front end side is relatively displaced upward, so that the elastic force acting indirectly on the side toward the off position of the valve stem 11 of the intermediate member 30 is weakened, and as a result, the intermediate member 30 is returned to the action transmission position by the torsion spring 33. By the above operation, the operation returns to the initial position shown in Fig. 2. Thus, the driver 1 of the present embodiment does not perform the operation of temporarily returning both the contact arm 6 and the switch lever 20 to the OFF position (single shot operation) However, the next driving operation cannot be performed, and it becomes a so-called single-shot machine. Then, unlike the above-described normal use sequence (single-shot operation), the user first opens the switch lever 20 to the open position. When the side body pulling operation is performed and the contact arm 6 is relatively moved toward the open position, the driving machine 1 of the present embodiment does not perform the driving operation (so-called air striking mechanism). 20 200909150=The switch lever 2 is first pulled from the initial state shown in the second figure, because the action arm 6b of the contact arm 6 is not on the 所示., ~, on the other hand, Become the valve stem 11 constantly squatting against the idle γ == Therefore, when the switch lever 2 is to be placed.

Moreover, the state shown in the fifth figure is after the end of the driving operation. In the state in which the switch lever 20 is still being pulled, the pressing operation of the main body portion 2 is released, and the contact arm 6 is returned to the closed position. The state shown in the sixth figure is shown in the second figure. In the initial state, the switch lever 20 is first pulled only, and the open state of the contact arm 6 is not performed, as shown in the seventh figure. The state indicates a state in which the contact arm 6 is opened from the state shown in Fig. 6. Thus, the fifth stage to the sixth figure respectively indicate different stages, and in the fifth and sixth figures, except for the trigger valve The same state is formed except for the position of the second valve body 13 with respect to the first valve body 12 in 10. In the state where the second valve body 13 is moved downward relative to the first valve body 12 as shown in Fig. 5 The second seal ring lib forming the valve stem 11 is hermetically fitted in the inner peripheral side of the second valve body 13. In this state, the valve stem lower chamber 17 that normally communicates with the pressure accumulating chamber 3a is The first pressure changing chamber 15 is in a state of being cut off, so that the compressed air is not supplied to the first pressure changing chamber 15 as described above, so that the second variable pressure chamber is still in the state in which the second valve body 13 is moved downward. 18 is still in a state of being open to the atmosphere, and as a result, since the head valve is in the open state in the main body portion 2, the piston stays at the bottom dead center. In contrast, the valve stem 11 is shown in Fig. 6 When the second seal ring lib is separated from the inner peripheral side of the second valve body 13, it is a slave valve Since the lower chamber 17 supplies compressed air to the first pressure changing chamber 15, the second valve body 13 moves up and supplies compressed air to the second pressure changing chamber 18, thereby being maintained in the main body portion 2 with the head valve closed. The state in which the piston is at the top dead center is still in the state shown in the second and third figures, and the second valve body 22 200909150 is connected to the first pressure changing chamber 15 from the south. # = i to 15 supply compressed air to move the second valve body 13 up. The 1C pressure chamber 1 supplies compressed air to the head 阙 closed state, and the state shown in the fourth figure is The first pressure changing chamber is large, and as a result, the second valve body 13 is moved downward and the second pressure changing chamber 18 is placed at a large position, so that the head valve is opened to move the piston downward to the driving operation state. [The material enters the shape of the crucible: as shown in the second and third figures, the chamber Is moved up by the second valve body 13 for the second casing 13 to open the seal ring 13b to change to the second A total of two compressed air states. In contrast, in the first state as shown in the fourth figure, the sealing ring 13b ^ of the second valve body 13 is cut off from the side of the compartment chamber, and on the other hand, the sealing ring gas path 2 is opened to become the second variable pressure. The chamber 18 is open to the atmosphere via the discharge path 3e. = "sample" is moved up and down correspondingly to each action phase by the second valve body 13 = the two pressure change chamber 18 is switched to a compressed air supply state (second map, = 'sixth, seventh diagram) and atmospheric open state ( The fourth figure and the fifth figure), whereby the head valve can be closed or opened. In the state shown in Fig. 4, Fig. 7, and Fig. 7, the position of the contact arm (the position of the arm portion 6b) is different, and the same shape as the point = the figure 6 indicates the contact arm 6 The closed position, the seventh figure shows the open position. Q: In the second embodiment, the stroke of the open position and the closed position of the contact arm 6 is set to an extremely small distance. 〃In the case where the normal driving operation is performed as shown in the third and fourth figures, the driving machine of the present embodiment configured as described above performs the opening operation of the contact arm 6 (main body portion). The next operation of 2), and the use of 23 200909150 on the position side of the action arm portion of the rotation action causes the inter-member to move the action arming arm portion 31 from the lateral direction to the;; f is the restriction of the intermediate member 30 via the idle The state of the side wall of the rod 22 and the intermediate structure, so that the orientation of the U toward the 阙 position _" is applied to the movement arm portion 6b) will move along the contact arm 6 (mainly the retracting spring Η The action does not act in the direction of movement. 盥 = acts in a substantially orthogonal direction, and when the body portion is pressed down, the following structure is formed, that is, during the pull-and-pull operation, the inter-rod moves up toward the 3=arm, and then the switch The lever applies a force to the side of the closed position; the force: the elastic force acts as the contact force as the lifting of the main body portion 2, and the elastic action acts on the switch lever to buckle her=force) Therefore, the = body portion is held on the lower part - the force on the side of the f side (Ϊ The contraction is made to the pair of the valve stem U toward the 阙 = , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The movement of the restriction arm 31 is different from the movement path.

2仃程L functions as a malfunction prevention function. Due to the contact, the amount of depression of the main body portion 2 during the driving operation is changed to the front end portion of the striker rail 5 (the opening of the material to be driven), and the precision of 24 200909150 is aligned with the punching material w. Into the position, you can make a higher precision in. In & 2, it is also possible to apply various changes to the implementation of the syllabary = 2 stone brothers, for example, although the exemplification has the ambiguity and only knows.

The drive of the shape of the '$刖钿 is also the same as the drive machine of the same == body drive type drive, for the electric type 3 turn = structure: then with two arms 3 32 The intermediate member may also be configured to use an intermediate member that moves linearly along the moving side of the contact arm. In this case, it is possible to configure the arm of the contact arm to advance and retreat in the middle of the middle of the structure, thereby restricting the straight line toward the side of the action blocking position. The rod moves at a sufficient distance to open the trigger valve, the core 2 and the intermediate member to move linearly to the action blocking position, and the idle rod = the movement is insufficient to result in a state in which the trigger valve is not opened, by which the member is laterally The pressing force is applied to the operating arm portion of the contact arm, so that the force of the valve stem can be blocked in the moving direction of the contact arm, so that the same effect can be obtained. Further, the direction in which the intermediate member is brought into contact with the operating arm portion of the contact arm may be set to be obliquely forward or in addition to the configuration in which the contact arm is substantially abutted from the direction in which the contact arm moves in the direction of the contact arm. The configuration in which the oblique rear side abuts at a certain inclination angle can block or greatly reduce the force of the valve stem to the contact arm regardless of the configuration. It is also possible to adopt a configuration in which the biasing mechanism for biasing the contact arm toward the closed position side is not using a compression damper such as a pneumatic damper or a buffer rubber: the stroke L is used in comparison with the conventional one. The closed position between the closed position and the open position is smaller than the conventional one. However, the configuration may be such that the configuration is not performed, and the contact arm is not moved. Even if it is compared with the past, it can act on the contact arm. As a result, the reaction of the body, from the day, or when the switch lever is pulled out, the main [picture is simple] D is called the operation of the hitting machine. Sex. Figure.
