BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail supply device for automatically adjusting the width of a nail supply passage for supplying a connecting nail to a nail striking portion of a nailing machine and the position of a check nail with respect to the connecting nail in the nail supply passage. Regarding

[0002]

2. Description of the Related Art There are several types of connecting nails for use in a nailing machine, depending on the connecting mode. Wire connecting nails in which a long wire is welded and connected to the nail shaft and a long plastic sheet are used. A sheet connecting nail in which a nail shaft is inserted through and supported by a bending tab of a connecting belt to connect the nail is well known. The former is often used for the construction of the base material because the cost is relatively low, and the latter is often used for the construction for the interior because the connecting members do not scatter. By the way, since these connecting nails have different width dimensions and shapes in the wire connecting material and the connecting strip made of the plastic sheet, and the connecting pitches of the nails are different, the widths of the nail supply passages are different when they are used. A dedicated nail driver is required.

Recently, a nail supply device has been proposed for using the connecting nails having different connecting modes with the same tool. For example, the member forming the guide wall of the nail supply passage is set to be slidable according to the difference in the width dimension of the wire connection nails or the sheet connection nails, and the width dimension of the connection nails can be shared by adjusting operation or automatic adjustment As a measure to achieve
Japanese Utility Model Laid-Open No. 62-92170 is known.

However, this technique cannot cope with the case where the connecting pitches of the connecting nails are different. Therefore, a technique for variably adjusting the supply mechanism corresponding to the connecting nails having different connecting pitches is required. For example, as a nail feeding mechanism corresponding to connecting nails having different connecting pitches, as shown in Japanese Utility Model Laid-Open No. 23968/1990, there is known one that adjusts the operation stroke of the nail feeding nails in accordance with the connecting pitch.

[0005]

An object of the present invention is to solve the above-mentioned drawbacks and to adjust the setting of the nail feeding mechanism according to the width of the nail supply passage and the connecting pitch of the nails according to the connecting mode of the connecting nails to be used. It is an object of the present invention to provide a nail supply device for a nailing machine that can use various types of nails without requiring any operation.

[0006]

In order to achieve the above-mentioned object, a nail supply device of a nailing machine according to the present invention includes a guide wall connected to a driving portion for driving a nail by a hammering mechanism and the driving portion. A nail supply path is formed between the nail member and a door member that is supported and is disposed opposite to the guide wall, and a nail supply mechanism that supplies the connecting nail in the nail supply path to the driving portion is provided on the guide wall. An adjusting plate that constitutes a part of the nail supply passage is disposed on the door member so as to face the guide wall, and the adjusting plate protrudes toward the guide wall and engages a connecting nail in the nail supply passage. A stop claw is provided, and the adjustment plate is supported so as to be movable in parallel with the nail supply passage in an oblique direction.

[0007]

To use the nail supply device having the above construction, the door member is first opened, the connecting nail is loaded in the magazine case, and the leading nail is set in the driving portion through the nail supply passage. . Then, the door member is closed. At this time, since the adjustment plate is biased by the spring, if the loaded connecting nail is a narrow connecting nail, the width of the nail supplying passage is narrowed by protruding into the nail supplying passage correspondingly, If the connecting nail is wide, the width of the nail supply passage is specified to be wide. Further, since the adjustment plate moves obliquely in parallel, the position of the check claw is automatically moved and adjusted according to the movement of the adjustment plate. After that, when the nail driving machine is operated to drive the nail, the nail in the driving portion is driven by the nail striking mechanism to be hammered out.

As described above, by closing the door member, the width of the nail supply passage and the position of the non-return pawl are automatically adjusted and set according to the width of the connecting nail used in the connecting mode. No adjustment operation is necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is a nail driving machine body having a striking mechanism for connecting nails, 2 is a nail driving portion which is hammered by a striking mechanism, and 3 is a nail supplying device for supplying a connecting nail to the driving portion. And 4 is a magazine case for the connecting nail a.

A nail supply passage 5 is provided between the driving section 2 and the magazine case 4, as shown in FIGS. 2 and 3.
Are formed. The nail supply passage 5 has a driving portion 2
Between the guide wall 6 and the door member 7 which is rotatably and rotatably supported by the driving portion 2 and is arranged to face the guide wall 6.

The guide wall 6 has a guide portion 8 on the head of the connecting nail a.
And the connecting nail a in the nail supply passage 5 is formed.
There is provided a nail supply mechanism for supplying the driving force to the driving section 2. This nail supply mechanism reciprocates a feed claw 9 provided so as to project into the nail supply passage 5 along the supply direction of the connecting nail a, and engages with the connecting nail a on the nail supply passage 5 during the forward movement. The leading nail is supplied to the driving section 2.

Next, the door member 7 includes an outer wall portion 7a and an upper wall portion 7
It is formed in a U shape from b and the lower wall portion 7c, and the adjusting plate 10 is arranged inside. The adjusting plate 10 has a guide wall portion 11 which faces the guide wall 6 and constitutes a part of the nail supply passage 5, and a recess 12 is formed in a substantially central portion of the guide wall portion 11. A check claw 13 is pivotally supported in the recess 12 so as to be rotatable. Check claw 13
The tip 13a of the spring 1 so that it projects into the nail supply passage 5.
Energized by 4. A spring 15 is arranged on the back surface of the guide wall portion 11 of the adjustment plate 10, and the adjustment plate 10 is constantly urged so as to protrude toward the nail supply passage 5 side. In addition, the pins 16 are provided on both sides of the adjustment plate 10.
The pin 16 is slidably inserted into the upper wall portion 7b and the lower wall portion 7c of the door member 7 in inclined guide grooves 17 which are inclined with respect to the nail supply passage 5, respectively. As a result, the adjusting plate 10 can move in parallel to the nail supply passage 5 in an oblique direction to adjust the width of the nail supply passage 5.

The inclined guide groove 17 is inclined so that the driving portion 2 side is separated from the nail supply passage 5 and the opposite side is close to the nail supply passage 5, so that the check claw 13 is driven by the check claw 13 as the nail supply passage 5 becomes wider. The reason why it is set to move to the side is that the connecting pitch of the connecting nail a is generally larger in the wire than in the connecting strip made of a plastic sheet.

In using the nail supply device having the above-mentioned structure, first the door member 7 is opened and the magazine case 4 is opened.
The connecting nail a is loaded inside, and the leading nail is set in the driving portion 2 through the nail supply passage 5. Then, the door member 7 is closed. At this time, if the loaded connecting nail a is a wire connecting nail, correspondingly, as shown in FIGS. 2 and 3, the adjusting plate 10 is translated by the spring 15 so as to project into the nail supply passage 5. The width of the nail supply passage 5 is narrowed by the guide wall portion 11 and the guide wall 6. The position of the check claw 13 is also automatically set. After that, when the nail driving machine is operated to drive the nail, the nail 20 in the driving portion 2 is hammered and driven by the hammering mechanism, and at the same time, the next nail is supplied to the hammering portion 2 by the operated nail supplying mechanism. It is possible to drive nails continuously.

When the sheet connecting nail is used in the nail driving machine, the door member 7 is opened, the sheet connecting nail is loaded in the magazine case 4, and the leading nail is passed through the nail supply passage 5 as described above. The door member 7 is closed by setting it in the driving part 2. At this time, as shown in FIG. 4, the adjusting plate 10 moves parallel to the seat connecting nail a1 so as to retract into the door member 7 against the spring 15, and the guide wall portion 11 thereof is moved.
The width of the nail supply passage 5 is increased by the guide wall 6 and the guide wall 6. Further, since the parallel movement of the adjusting plate 10 is performed in the oblique direction along the inclined guide groove 17, the position of the check claw 13 also moves accordingly, as shown by the dotted line in FIG. 2, and the sheet connecting nail a is connected. It is set to correspond to the pitch.

As described above, by closing the door member 7, the width of the nail supply passage 5 and the position of the check claw 13 are automatically adjusted and set according to the width of the connecting nail a of the connecting mode used. Therefore, the operation for adjustment is not necessary and the device can be easily used.

If the tilt guide groove 17 of the door member 7 is formed as a separate member so that the tilt direction can be freely changed, the range of selection becomes larger. For example, the inclination direction is opposite to that of the above-described example so that the driving portion 2 side is closer to the nail supply passage 5 and the opposite side is closer to the nail supply passage 5, so that as the nail supply passage 5 becomes narrower, the check claw 13 is driven. Move to side 2. Therefore, it is possible to cope with a usage mode in which the connection pitch of the sheet connection nails is larger than the connection pitch of the wire connection nails.
