Abstract

PROBLEM TO BE SOLVED: To provide an easy-to-use driving machine capable of conducting switching among a continuous mode, a sequential mode, and a trigger lock mode without troublesome operation, by solving such a problem that, in a conventional driving machine capable of conducting switching between a continuous mode and a sequential mode, switching operation is troublesome because a switching operation member for a trigger lock mechanism is mounted independently of an operating member for mode switching. SOLUTION: This driving machine is provided with a spindle rotatably supporting a trigger 30 on a driving machine body. The spindle is rotatably supported on the driving machine body and the trigger 30 is rotatably supported on an eccentric shaft part 35b formed at the spindle. When the spindle rotates to a successive mode position, a sequential mode position, or a trigger lock mode position, the eccentric shaft part 35b is displaced, so that the rotational center of the trigger 30 is displaced. Taking advantage of this displacement, the operating mode of the driving machine body is switched.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving machine such as a nail driving machine, a screw driving machine or a tucker.

[0002]

2. Description of the Related Art For example, an air-driven nail driving machine, which is a type of a driving machine, includes a driving machine body having a built-in percussion piston which moves up and down using compressed air as a driving source. Is moved downward, and driving tools (nails) are driven one by one from the tip of the driver guide. Conventionally, in order to prevent an inadvertent driving operation (erroneous operation), a driving arm of this type is provided with a contact arm for preventing an erroneous operation at the end of the driver guide. The pulling operation of the trigger is configured to be effective only when the arm is relatively moved upward by pressing the arm against the driving material. When the trigger is pulled effectively, the trigger valve turns on and the supply / exhaust state of the driving machine changes,
As a result, the impact piston of the driving machine body moves down,
A driving tool is driven out from a tip of a driver guide provided at a lower portion of the driving machine main body.

Further, in a driving machine having the above-described contact arm, in order to more reliably prevent malfunction, the pull operation of the trigger is performed regardless of whether the trigger operation or the contact arm upward operation is performed first. Trigger mode is enabled only when the trigger operation is performed while the contact arm is first moved upward, and the trigger operation is enabled only when the reverse operation is performed. There has been provided a driving machine which is capable of arbitrarily switching a "sequential mode" in which a pulling operation is invalidated and a driving tool is not driven out according to a working mode (for example, Japanese Patent Application Laid-Open No. H10-264052). According to the above configuration, the efficiency of the driving operation can be improved by selecting the continuous mode, while double driving due to the recoil at the time of driving can be prevented by selecting the sequential mode. Further, for example, in order to reliably prevent a malfunction of the driving machine body when the driving machine is carried (other than during a driving operation), a device provided with a trigger lock mechanism (stop mode) for pulling a trigger and locking the operation of the driving machine is not available. Provided. According to this trigger lock mechanism, the operation of the driving machine main body can be reliably prevented even if the contact arm moves while interfering with another part when the trigger is carried with a finger.

[0004]

However, according to the above-mentioned conventional driving machine, the operation member for switching the trigger lock mechanism is provided separately from the operation member for switching between the continuous mode and the sequential mode. The switching operation was troublesome, and the usability was not good in this respect. Therefore, an object of the present invention is to provide a driving machine that can switch between a continuous mode, a sequential mode, and a stop mode without performing a troublesome operation, and that is easy to use in this respect.

[0005]

SUMMARY OF THE INVENTION For this purpose, the present invention provides a driving machine having the structure described in the claims. According to the driving machine according to the first aspect, by switching the single operating member, the mode can be switched to the continuous mode, the sequential mode, or the stop mode. The operation is not complicated, and the usability of the driving machine can be improved in this point.

According to the second aspect of the present invention, the operating mode of the driving machine can be set to a continuous mode, a sequential mode, or a stop mode by rotating the spindle of the trigger to displace the center of rotation of the trigger. Since the switching can be performed, the above operation and effect can be obtained with a simple configuration.

According to the third aspect of the present invention, in the stop mode, the trigger interferes with the main body of the driving machine so that the pulling operation of the trigger is prohibited. A reliable trigger lock state can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 shows a nailing machine 1 as an example of a driving machine. This nailing machine 1
A nailing machine main body 2 and a handle portion 3 provided to protrude laterally from a side portion of the nailing machine main body 2 are provided. or,
On the lower surface of the nailing machine main body 2, a nail driving portion 4 for driving a nail is provided. A nail magazine 5 for loading a large number of nails is provided between the nail driving portion 4 and the handle portion 3. A nail (not shown) that reciprocates with compressed air is provided in the nailing machine main body 2, and a nailing driver is attached to the piston. The driver is guided so as to be able to reciprocate in the vertical direction in the drawing (the nail driving direction) via the inner peripheral side of the driver guide 6 of the nail driving section 4.

The driver guide 6 has a contact arm 7
Is mounted to be vertically movable. The contact arm 7 includes a contact portion 7a located on the lower end side of the driver guide 6, an extension 7b extending from the contact portion 7a along the driver guide 6, and an action portion 7c provided at an upper end of the extension 7b. Have. The action portion 7c is supported by a support bracket 9 attached to the nailing machine main body 2 so as to be movable up and down, and its tip (upper end) reaches the vicinity of a trigger valve 40 attached to the base of the handle portion 3. I have. A driving depth adjusting device 8 is interposed between the action portion 7c and the extension portion 7b. By operating the driving depth adjusting device 8, the position of the action portion 7c with respect to the extension portion 7b can be changed, whereby the driving depth of the nail can be adjusted.

Since the contact arm 7 is urged downward by the compression spring, the contact arm 7 is located at the lower end when no upward movement is performed. When the contact arm 7 is located on the lower moving end side, the contact portion 7a projects further from the lower end of the driver guide 6 by a certain dimension. FIG. 1 shows this state. The dimension that the contact portion 7a protrudes from the lower end of the driver guide 6 is a dimension that allows the contact portion 7a and thus the contact arm 7 to move upward.

The contact arm 7a is applied to a nailing material (not shown) and the nailing machine 1 is pressed in the nailing direction (downward in FIG. 1) to relatively move the contact arm 7 against the compression spring. Can be moved up. When the contact arm 7 moves upward, the action part 7c is integrally displaced upward. The upward displacement of the action portion 7c is one condition for the trigger valve 40 to be turned on and the nailing operation to be performed in the nailer body 2. Another condition for nailing motion is
That is, the trigger 30 is effectively pulled.

The trigger 30 is supported by bifurcated support walls 2a and 2b provided on the side of the nailing machine body 2 via a support shaft 35 so as to be rotatable up and down. The support state of the trigger 30 is shown in FIGS. 2 and 3. As shown, the support shaft 35 has a large diameter portion 35a and a small diameter portion 35b.
The small diameter portion 35b is eccentric with respect to the large diameter portion 35a. In FIG. 3, the rotation axis of the large diameter portion 35a is indicated by reference numeral C1, and the rotation axis of the small diameter portion 35b is indicated by reference numeral C2. The interval between the rotation axis C1 and the rotation axis C2 is the eccentric distance L of the small diameter portion 35b with respect to the large diameter portion 35a. In the present embodiment, the small diameter portion 35b corresponds to the eccentric shaft portion described in claim 1. As shown in FIG. 3, the large diameter portion 35a of the support shaft 35 is
Support hole 2c formed in one (left side in the figure) forked wall portion 2a
It is supported rotatably. The distal end side of the small diameter portion 35b is supported by the support cap 36 rotatably attached to the other (right side in the figure) bifurcated wall portion 2b so as to be axially immovable. Thereby, the small diameter portion 35b is connected to the two forked wall portions 2a,
It is supported in a bridging manner between 2b. This small diameter portion 35
The trigger 30 is rotatably supported by b. Therefore,
The center of rotation of the trigger 30 is the rotation axis C2.

A knob 37 for rotating operation is attached to the end face of the large diameter portion 35a. This knob 37
A steel ball 38 is sandwiched between the two forked wall portions 2a. The steel ball 38 is compressed by a compression spring 39.
A hemispherical lock hole 2d (or 2) provided in the bifurcated wall 2a
e or 2f). This lock hole 2
d, 2e, and 2f are formed at three locations on the circumference around the rotation axis C1. Between the first lock hole 2d and the second lock hole 2e, the second lock hole 2e and the third lock hole 2f
Are set at an interval of 90 ° from each other. When the knob 37 is rotated, the steel ball 38 is compressed by the compression spring 39 into the first lock hole 2d (or the second lock hole 2e,
Alternatively, the support shaft 35 is fitted into the third lock hole 2f), whereby the support shaft 35 is locked at three positions around the rotation axis C1.

When the support shaft 35 rotates, the small-diameter portion 35b moves on a circumference centered on the rotation axis C1 and having a radius equal to the eccentric distance L. When the steel ball 38 is locked in the first lock hole 2d, the small diameter portion 35b of the support shaft 35 is located above the rotation axis C1 of the large diameter portion 35a in FIG. Hereinafter, this switching state is referred to as a “continuous mode”. When the support shaft 35 is rotated 180 ° counterclockwise in FIG. 2 from the above-mentioned continuous mode to lock the steel ball 38 in the second lock hole 2e, the small diameter portion 35b of the support shaft 35 2, it is located below the rotation axis C1. Less than,
This switching state is called “sequential mode”.

When the steel shaft 38 is locked in the third lock hole 2f by rotating the support shaft 35 further counterclockwise by 90 ° from the sequential mode, the small diameter portion 35b of the support shaft 35 becomes In FIG. 2, it is located on the right side of the rotation axis C1 (on the side of the trigger valve 40). Hereinafter, this switching state is referred to as “stop mode”. In FIG. 2, the support shaft 35
Is added to the small-diameter portion 35b when the mode is switched to the continuous mode, the subscript "S" is added to the small-diameter portion 35b when the mode is switched to the sequential mode, and when the mode is switched to the stop mode. Attaching a suffix "T" to the small diameter portion 35b,
Each was distinguished. In FIG. 2, the small diameter portion 35bR in the continuous mode and the small diameter portion 35bS in the sequential mode are shown.
Is indicated by a two-dot chain line.

Next, a stopper projection 30a is provided on the upper part of the trigger 30 so as to project rearward (to the right in FIG. 2). The stopper projection 30a is
5 is switched to the stop mode, the bifurcated wall 2
It is located below the stopper wall 2g which is formed to protrude from the base of a, 2b. Therefore, when the trigger 30 is pulled, the stopper protrusion 30a interferes with the stopper wall 2g, and the pull operation of the trigger 30 is prohibited. On the other hand, when the support shaft 35 is switched to the continuous mode, the stopper projection 30a is positioned above the stopper wall 2g, and when switched to the sequential mode, the stopper projection 30a is located below the stopper wall 2g. Located far enough away. For this reason, at the time of the pulling operation of the trigger 30, the stopper projection 30a is moved to the stopper wall 2g.
Therefore, the triggering operation of the trigger 30 is allowed.

As described above, when the support shaft 35 is switched to the continuous mode or the sequential mode, the trigger 30
When the operation is switched to the stop mode, the pulling operation of the trigger 30 is prohibited, and the position of the support shaft 35 and the large-diameter portion 3 are adjusted so as to satisfy such a function.
The eccentric distance L between 5a and the small diameter portion 35b is set, and the position and shape of the stopper projection 30a and the stopper wall 2g are set. An idler 3 is provided on the rear side of the trigger 30.
1 is attached. The idler 31 is provided rotatably up and down via a support shaft 31 a attached to a lower portion of the trigger 30. The idler 31 extends upward from the support shaft 31a and reaches near the support shaft 35.

A trigger valve 40 is mounted on the base of the handle portion 3 behind the trigger 30 configured as described above. This trigger valve 40 has the same configuration as the conventional one, and does not require any particular change in practicing the present invention. This trigger valve 40 has a valve stem 41 (see FIGS. 1 and 4 and subsequent figures). This valve stem 4
When "1" is pushed in a certain dimension, the trigger valve 40 is turned on. When the trigger valve 40 is turned on, compressed air is supplied to the upper air chamber of the striking piston, and the striking piston moves downward, whereby one nail is driven out by the driver. Since the compression spring 42 is interposed between the idler 31 and the trigger valve 40, the idler 31 is biased in a direction away from the valve stem 41.

The trigger 30 is thus biased in the direction of the reverse pulling operation (original position side, clockwise in the drawing), and the trigger 30 is pulled against the biasing force. In a state where the trigger 30 is not pulled, the stopper portion 30b provided at the front portion thereof is held at the original position by abutting on the support bracket 9. 1, 4, 5, 9, 10, 14, and 15 show a state where the trigger 30 is located at the original position.

Next, the validity and invalidity of the trigger valve 40 due to the difference in the mode position of the support shaft 35 and the difference in the operation form such as whether the contact arm 7 is moved upward or the trigger 30 is pulled first. explain. FIG.
Is a state in which the support shaft 35 is positioned in the continuous mode (the small diameter portion 3).
5bR is located above the rotation axis C1 of the large-diameter portion 35a). As shown in FIG. 5, when the contact arm 7 is moved upward from this non-operation state, the upper portion of the idler 31 is pushed by the action portion 7c, so that the idler 31 is compressed.
2 to the trigger valve 40 side, whereby the valve stem 41 is slightly pushed in. However,
At this stage, the trigger valve 40 is not turned on because the pushing amount of the valve stem 41 is insufficient.

Next, as shown in FIG. 6, after the contact arm 7 is moved upward, the trigger 30 is pulled (counterclockwise rotation in the figure, the same applies hereinafter), and the spindle of the idler 31 is rotated. Since 31a moves to the trigger valve 40 side, the idler 31 is largely displaced as a whole to the trigger valve 40 side, whereby the valve stem 41 is further pushed in and the trigger valve 40 is turned on. When the trigger valve 40 is turned on, a nailing operation is performed. Also, FIG.
In the non-operation state in the continuous mode, the stopper projection 30a of the trigger 30 is located above the stopper wall 2g of the nailing machine body 2 as shown in FIG. Therefore, the trigger 30
During the pulling operation, the stopper projection 30a does not interfere with the stopper wall 2g, and thus the pulling operation of the trigger 30 is allowed.

Conversely, when the trigger 30 is first pulled, as shown in FIG. 7, the support shaft 31a of the idler 31 is displaced toward the trigger valve 40. However, since the amount of movement of the idler 31 is small, the valve stem 41 hardly moves, so that the trigger valve 40 does not turn on. Then, as shown in FIG. 8, by further moving the contact arm 7 upward, the upper part of the idler 31 is compressed by the compression spring 42.
Against the trigger valve 40 side. This allows
The valve stem 41 is pushed in by a sufficient amount to turn on the trigger valve 40, so that a nailing operation is performed. Also in this case, the stopper projection 30a of the trigger 30 does not interfere with the stopper wall 2g on the main body 2 side, and the pulling operation of the trigger 30 is allowed. As described above, with the support shaft 35 in the continuous mode, the nailing can be performed by first moving the contact arm 7 upward and then pulling the trigger 30 (first operation mode). Conversely, nailing can also be performed by first pulling the trigger 30 and then moving the contact arm 7 upward (second operation mode).

Next, a case will be described in which the support shaft 35 is switched from the above-mentioned continuous mode by 180 ° counterclockwise in the drawing to the sequential mode. In this case, the small diameter portion 35bS of the support shaft 35 is connected to the rotation axis C1 of the large diameter portion 35a.
Since the rotation support point (small diameter portion 35bS) of the trigger 30 is smaller than the case of the above-mentioned continuous mode, the rotation support point of the trigger 30 is smaller than that of the above-mentioned continuous mode.
Accordingly, the idler 31 is displaced downward by 2 L as a whole as compared with the case of the continuous mode. FIG. 9 shows a non-operation state in which neither the upward operation of the contact arm 7 nor the pull operation of the trigger 30 is performed. When the contact arm 7 is first moved upward as shown in FIG. 10 from the non-operation state in the sequential mode, the upper portion of the idler 31 is moved by the action portion 7c as in the case of the continuous mode.
It is pushed to the 0 side. In this case as well, the valve stem 41 is slightly pushed in, but the amount is insufficient, so that the trigger valve 40 does not turn on. After the contact arm 7 is moved upward, the trigger 30 is pulled (first operation mode).
As a result, as shown in FIG. 11, the idler 31 is displaced as a whole to the trigger valve 40 side, whereby the valve stem 41 is displaced.
Is pushed in by a sufficient amount, so that the trigger valve 40 is turned on and nailing is performed.

Next, in the sequential mode, when the trigger 30 is first pulled from the non-operation state shown in FIG. 9 as shown in FIG.
1a side (lower side in the figure) moves to the trigger valve 40 side more than its front side (upper side in the figure), and as a result, the front end of the idler 31
Retreat below the movement route of c. At this stage, the valve stem 41 has not been pushed. After the trigger valve 30 is pulled as described above, the contact arm 7 is moved upward as shown in FIG.
Pass through the idler 31 without being hit by the idler 31. Therefore, the idler 31 is not rotated toward the trigger valve 40.

Thus, in the sequential mode, after the trigger 30 is pulled, the contact arm 7
Is operated upward (second operation mode), the valve stem 41 is not pushed by the idler 31, so that the trigger valve 40 is not turned on, and therefore, the nailing operation is not performed. That is, since the trigger valve 40 does not turn on even if the trigger 30 is pulled, the pulling operation of the trigger 30 becomes invalid. When the support shaft 35 is switched to the sequential mode, the stopper projection 30a of the trigger 30 is moved to the stopper wall 2g.
Is moved to a position sufficiently distant from the bottom of the stopper wall 30a when the trigger 30 is pulled.
g is not interfered with, and thus the pulling operation of the trigger 30 is allowed.

Next, a description will be given of a case where the support shaft 35 is further rotated 90 ° counterclockwise in the figure from the sequential mode to switch to the stop mode. In the case of this stop mode, as shown in FIG.
However, in the illustrated height direction, it is located in the middle between the continuous mode and the sequential mode, and in the horizontal direction in the illustrated direction, it is displaced toward the trigger valve 40 by the dimension L more than the continuous mode and the sequential mode. In the non-operation state, the stopper projection 30a is
g from below and the trigger 30
Cannot be operated.

In a state where the trigger 30 cannot be pulled in this manner, as shown in FIG.
Is operated by the action portion 7c even when the idler 31 is moved upward.
Is pushed to the trigger valve 40 side, and the valve stem 41 is slightly pushed in. However, the trigger valve 40 is not turned on because the amount is insufficient, so that the nailing operation is not performed.

According to the nailing machine 1 of the present embodiment described above, the knob 37 is gripped and the support shaft 35 (single operating member) is turned to change the operation mode to the continuous mode or the sequential mode. Alternatively, since the mode can be switched to the stop mode, the operation is less troublesome than in the related art, and in this regard, the usability of the driving machine 1 can be improved. When the operation mode is set to the continuous mode, the trigger valve 40 is turned on and the nailing operation is performed regardless of whether the operation of moving the contact arm 7 upward or the operation of pulling the trigger 30 is performed first. When switching to the sequential mode,
Trigger 3 with the contact arm 7 raised
The nailing operation is performed only when the pulling operation is performed at 0, and in the opposite case, the pulling operation of the trigger 30 is invalidated, the trigger valve 40 is not turned on, and therefore the nailing operation is not performed. According to the sequential mode, the nailing operation is not performed even if the contact arm 7 is moved up again while the trigger 30 is being pulled, so that double nailing of the nail can be reliably prevented.

Further, when the support shaft 35 is switched to the stop mode, the pulling operation of the trigger 30 is prohibited. For this reason,
Even if the contact arm 7 is moved upward in the stop mode, the trigger valve 40 is not turned on, so that the nailing machine 1 can be reliably prevented from being erroneously operated. According to this stop mode, for example, when the nailing machine 1 is carried, even if the contact arm 7 is moved upward due to contact with another part or the like, the nailing operation is not performed. Is reliably prevented.

Various modifications can be made to the embodiment described above. For example, the configuration in which the support shaft 35 is a single operation member has been exemplified, but other members can be used as the single operation member described in the claims.
For example, it is also possible to provide the operating section 7c as illustrated above so as to be movable in three stages in the upper and lower stages in the figure, and to use the operating section 7c as a single operating member. In this case, when the operating portion 7c is moved to the upper position (stop mode position), the operating portion 7c is moved to the tip of the idler 31 regardless of whether the contact arm 7 is moved up or down and the trigger 30 is pulled. There is no interference, so that the trigger valve 40 can be turned off (stop mode) even when the contact arm 7 is moved upward and the trigger 30 is pulled.

When the operating portion 7c is moved to the middle position (sequential mode position), the idler 31 is operated only when the contact arm 7 is first moved upward.
, So that the trigger valve 40 is turned on when the trigger 30 is pulled next time.

Further, when the operating portion 7c is moved to the lower position (continuous mode position), the contact arm 7 can be moved upward regardless of whether the contact arm 7 is moved up or the trigger 30 is pulled. For example, the idler 31 is pushed by the action portion 7c, and therefore, a continuous mode in which the trigger valve 40 is turned on can be provided. In addition, the above-mentioned action portion 7
The same operation and effect as described above can also be obtained by a configuration in which c is rotated in parallel to move in three stages of upper, middle, and lower stages.

Further, by switching the rotation fulcrum of the idler 41 up and down to three positions and switching the position with respect to the action portion 7c in three stages, it is possible to switch between the continuous mode, the sequential mode, and the stop mode. Further, even when the length of the idler 41 (the height of the tip portion) can be switched in two stages, the same operation and effect as described above can be obtained.

The present invention is not limited to the nailing machine 1 described above, but may be any other driving machine, such as a tucker or a screw driving machine, for switching the operation mode (continuous mode, sequential mode or stop mode). It can be widely applied to driving machines.
