Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic nailing machine for a person to automatically drive a nail into wood, gypsum board or the like without using a wood chipper at a construction site.

[0002]

2. Description of the Related Art Conventionally, as this type, for example,
There is one as shown in FIG.

This is a pneumatic automatic nailing machine 1 having a nail driving means for driving the nail 4 from the nail projecting opening 1a and a nail supplying means for supplying the nail 4 to the nail driving means 1 by using the pneumatic automatic nailing machine 1. The vertical frame 3 is nailed. That is,
Apply the peripheral edge portion 2a of the panel 2 to the mounting surface of the vertical frame 3 and calculate the position of the nail projecting opening 1a of the automatic nailing machine 1 so that the nail 4 is driven into the contact area 3a, particularly the center portion thereof. It is decided and nailed in order.

In the frame wall construction method, for example, the vertical frame 3 is used.

This type is described in Japanese Utility Model Publication No. 55-50701 and Japanese Utility Model Publication No. 63-186569.

[0006]

However, in such a conventional one, the nail projecting opening 1 is so designed that the nail 4 is driven into the central portion of the contact area 3a between the vertical frame 3 and the panel 2.
Since the position of “a” is determined by the calculation and the nail 4 is driven in, it is easy for the blank or the like in which all or part of the nail 4 comes off the vertical frame 3. Further, if the vertical frame 3 is hidden by the panel 2, it is difficult to confirm even if a blank driving or the like occurs, and reliability of nailing work is low.

In particular, as shown in FIG. 6, when two panels 2 and 2 are nailed to the same surface of one vertical frame 3, the contact areas 3a and 3a become narrow, so that blanking or the like occurs. Is more likely to occur, and the worker must pay close attention to prevent this, which causes a delay in work.

Furthermore, since the operator nails the nails 4 from the peripheral edge 2b of the panel 2 so that the nails 4 will be driven in a constant position, the positions of the nails 4 will vary and the appearance quality will be impaired. It was

Therefore, the present invention provides an automatic nailing machine capable of always nailing to an appropriate position without idle driving and making the nailing position from the peripheral edge of the material to be nailed constant. The challenge is to provide.

EXAMPLES The present invention will be described below based on examples.

1 to 3 show a first embodiment of the present invention.

In this first embodiment, the automatic nailing machine 1
Is a nail driving means for driving the nail 4 by using air pressure,
Further, the nail driving means has a nail supplying means for supplying the nail 4 to the nail driving means, and the nail 4 is automatically driven into the panel 2 as a hit material. Reference numeral 1a in FIG. 1 denotes a nail projecting opening from which a nail 4 is emitted, and a guide plate 5 as a guide member for maintaining a nail 4 driving position from a peripheral edge 2b of a panel 2 at a desired position at a root portion 1b thereof. It is installed.

The guide plate 5 is made of a steel plate and has an L shape as shown in FIG. The guide piece 5d
5a is thin, and when the guide plate 5 is attached to the base portion 1b of the nail projecting opening 1a, the tip portion 5a of the guide piece 5d is arranged at the nail projecting opening 1 according to the thickness of the panel 2.
The length of the guide piece 5d is designed so as to project slightly forward of the tip of a. Further, a slit 5b as shown in FIG. 2 is opened in the mounting piece 5c, and the slit 5b is inserted into the root portion 1b of the nail projecting opening 1a,
As shown in FIG. 3, the nut 6 is screwed into the screw cut in the root portion 1b and tightened to fix the guide plate 5.

At this time, as shown in FIG. 3, in advance, the distance h from the center of the nail projecting opening 1a to the tip 5a is a desired distance, that is, from the peripheral edge 2b of the panel 2 to the nail 4 within the contact area 3a.
The insertion position of the slit 5b into the root portion 1b is adjusted so that the distance to the position where the user wants to hit is reached.

Next, a procedure for nailing the panels 2 and 2 to the vertical frame 3 using the automatic nailing machine 1 having such a configuration will be described.

First, a contact area 3a between the vertical frame 3 and the panel 2
However, the peripheral edge portion 2a of the panel 2 is applied to the mounting surface of the vertical frame 3 so as to be approximately half the width H of the frame material 3, and is temporarily fixed to the upper and lower frames (not shown).

Next, as described above, the nail projecting opening 1a is previously prepared.
The nail 4 is driven into the panel 2 and the vertical frame 3 in the following manner using the automatic nailing machine 1 in which the distance h from the center to the tip 5a is adjusted to a desired distance. That is, the tip portion 5a of the guide plate 5 is applied to the peripheral edge 2b of the panel 2, and nailing is performed while the position of the nail projecting opening 1a is determined. This is panel 2
Repeat at regular intervals in the vertical direction.

After the nailing of the first panel 2 is completed, the peripheral edge portion 2a of the second panel 2 is applied to the mounting surface of the vertical frame 3 and temporarily fixed to the upper and lower frames (not shown). At this time, the peripheral edge 2b and the peripheral edge 2b are considered in consideration of the assemblability of the panels 2 and 2.
The width and the like of the panels 2 and 2 are designed so that a slight gap is formed between them.

Next, referring to FIG. 1, the guide plate 5 is rotated so that the tip 5a of the guide plate 5 comes to the left side of the nail projecting opening 1a, and as described above, the tip 5a extends from the center of the nail projecting opening 1a. The distance h to is adjusted to the desired distance.

Then, the tip portion 5a of the guide plate 5 is applied to the gap between the peripheral edges 2b, and nailing is performed while the position of the nail projecting opening 1a is determined.

In the automatic nailing machine 1 having such a structure, the distance h from the center of the nail projecting opening 1a to the tip portion 5a of the guide plate 5 is adjusted to a required distance and the peripheral edge 2b of the panel 2 is adjusted. By hitting the tip portion 5b of the guide plate 5 while fixing the position of the nail projecting opening 1a, all or part of the nail 4 does not come off from the vertical frame 3 and the nail is not hit. Can be nailed in position. For this reason, unlike the conventional case, the worker can perform the nailing work without paying attention to the idle driving or the like, and the work can be promoted.

Since the distance h from the center of the nail projecting opening 1a to the tip 5a of the guide plate 5 is adjustable,
The nail 4 can be driven into an appropriate position according to a change in the width H of the vertical frame 3. Similarly, by rotating the guide plate 5 and changing the direction of the tip portion 5, it is possible to apply not only to the vertical and horizontal directions but also to the case where the panel 2 is obliquely attached.

Further, the nail 4 driving position from the peripheral edge 2b is always kept constant, and the nail 4 position does not vary as in the conventional case, so that the appearance quality can be improved.

On the other hand, since the guide plate 5 has a flat plate shape along the peripheral edge 2b, the stability of the guide can be improved and the working accuracy can be improved.

FIG. 4 shows a second embodiment of the present invention.

In this embodiment, the nail projecting openings 7a, 7a are provided one on the left and one on the right, and the nails 4, 4 are driven into the peripheral edge portions 2a, 2a at the same time. 1

That is, a substantially square guide plate 8 is fixed to the holding portion 7b at the center of the nail projecting openings 7a, 7a by bolts (not shown). Similar to the case of the first embodiment, this guide plate 8 has a thin tip portion, and each nail projecting port 7 is formed from this tip portion.
The distances to the centers of a and 7a are designed so that the nail 4 is driven into an appropriate position, as in the case of the first embodiment.

To nail using the automatic nailing machine 7,
First, on the mounting surface of the vertical frame 3, the peripheral edge portions 2a of the panels 2 and 2,
2a is applied almost evenly, and the panels 2 and 2 are temporarily fixed to upper and lower frames (not shown). Then, the tips of the guide plates 8 are applied to the gaps between the peripheral edges 2b, and the nails 4 and 4 are simultaneously driven while determining the positions of the nail projecting openings 7a and 7a.

As described above, in the second embodiment, the automatic nailing machine 7 is used.
Since two nail projecting openings 7a, 7a are provided in the central portion of the nail 7 and a guide plate 8 for determining the position of the nail projecting openings 7a, 7a is attached to the central portion thereof, the panels 2 and 2 are simultaneously attached to the vertical frame 3.
It is possible to further improve the working efficiency by nailing the nails to the nails and keeping the nails 4 and 4 driving positions from the peripheral edges 2b and 2b always constant.

The other structure and operation are the same as those of the first embodiment, and the description thereof will be omitted.

FIG. 5 shows a third embodiment of the present invention.

This embodiment is different from the automatic nailing machine 7 of the second embodiment in that a tapered guide pin 9 is used as a guide member instead of the guide plate 8 of the second embodiment. . Thereby, for example, the peripheral edge 2 of the panel 2
nails 4 from the edge 2b even if b is bent
The driving position can be kept constant.

The other structure and operation are the same as those of the second embodiment, and the description thereof will be omitted.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. However, it is included in the present invention. For example, in the above embodiment, the tip end portion of the guide member is tapered, but it may be stepped, for example, depending on the shape of the peripheral edge 2b of the panel 2 and the working conditions.

[0043]

As explained above, according to the present invention, the guide member of the automatic nailing machine is applied to the peripheral edge of the material to be nailed, so that the nail is always pressed from the peripheral edge of the material. The driving position can be maintained at a desired position. That is, by setting in advance the distance from the contact point of the guide member with the peripheral edge of the material to be nailed to the nail projection opening is equal to the distance from which the nail is to be driven from the peripheral edge of the material to be hammered, there is always no blanking. , It can be nailed in a proper position. For this reason, unlike the conventional case, the worker can perform the nailing work without paying attention to the idle driving or the like, and the work can be promoted.

Further, since the nailing is performed on the basis of the peripheral edge of the material to be hammered, the nail driving position from the peripheral edge of the material to be hammered is always kept constant and the nail position does not vary as in the conventional case.
The appearance quality can be improved.

Further, by providing two nail projecting openings so as to sandwich the guide member, it is possible to nail two adjacent workpieces at the same time and at a fixed position from their respective peripheral edges. .

On the other hand, by making the guide member flat along the peripheral edge of the material to be stamped, the stability of the guide can be improved and the working accuracy can be improved, and by making the guide member pin-shaped. Even when the peripheral edge of the material to be struck is bent, it is possible to follow the bending and guide.
