A hose 10 to transfer a fragment 13 of the plastic connection belt is connected to the other side part, and when the tip of the block 7 is abutted on a member 12 to be driven to drive the nail, the fragment 13 of the plastic connection belt which is broken and scattered in the block 7 is transferred to the prescribed place by the hose 10 through the air from the air blowing-in means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nailing machine using a connecting nail in which a large number of nails are connected to each other through a plastic connecting belt, and collects and disposes fragments broken and broken at the time of driving the nail in one place. Regarding a processing device.

[0002]

2. Description of the Related Art Generally, in this type of nail driving machine, when a leading nail of a plastic connecting belt is hit with a driver when driving a nail, the impact causes the plastic connecting belt to break and scatter.

[0003]

However, in a place where a large number of nails are driven in one place, such as a site of the two-by-four method or a packing / prefabricated factory, a large amount of debris of the connecting belt scatters and the foot slips. Becomes easier,
It was dangerous.

The present invention solves the above-mentioned drawbacks and provides a debris processing device at the time of nailing in a nailing machine for a coupled nail, which is capable of moving the debris of the coupling belt to a predetermined place without scattering at the time of nailing. Is the task.

[0005]

In order to solve the above-mentioned problems, a fragment processing device for nailing in a nailing machine for connecting nails according to the present invention is a connection in which a large number of nails are connected through a plastic connecting band. A nailing machine for nails, which is a nailing machine for connecting nails, in which connecting nails are sequentially supplied to a nose part provided at the tip of the nailing machine main body and hammered by a driver provided in the nailing machine main body. In the above, a cylindrical block is attached to the tip of the nose part, and an air blowing means is connected to one side part of the block, and a hose for transferring a fragment of a plastic connecting band is connected to the other side part, When the tip of the block abuts the material to be driven and nails it,
It is characterized in that the fragments of the plastic connecting band which are broken and scattered in the block are transferred to a predetermined place by a hose by the air blown from the air blowing means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a main part of a nailing machine for connecting nails according to the present invention. In the figure, reference numeral 1 is a nailing machine main body, and 2 is a nose portion provided at the tip thereof. is there. The nose portion 2 is provided with a magazine (not shown), and the magazine is loaded with connecting nails 3 and a feeder for the same.

As shown in FIGS. 3 (a) and 3 (b), the connecting nail 3 is formed by connecting a large number of nails 5 via a plastic connecting band 4. A plastic ring is fixed to the nail shaft. Each nail 5 is held in a holding hole 6 of the connecting band 4.

Next, a cylindrical block 7 is attached to the tip of the nose portion 2, and an elastic ring member 8 such as sponge or rubber is attached to the tip of the block 7. In addition, a blow tube 9 that is connected to an air blowing device as air blowing means is connected to one side of the block 7. A hose 10 for transferring the fragments of the plastic connecting band 4 is connected to the other side of the block 7. The tip of the hose 10 is open at a predetermined place. It should be noted that the air blowing device may be configured to operate in response to a driven material detection signal of the contact valve 11 described below, and to stop operating when the generation of the signal is stopped after the driving operation of the nail 5.

Reference numeral 11 denotes a contact valve, which detects that the tip of the nose portion 2 is in contact with the material 12 to be driven and outputs a signal to enable driving of the nail driver.

Next, the operation mode of the debris processing device having the above-mentioned structure will be explained. When the tip of the block 7 (the elastic ring member 8) is pressed against the driven material 12 as shown in FIG. Is operated and the nail driving operation is prepared. Then, when the nail driving machine is operated, the driving mechanism is actuated to drive the driver, and the nail 5 in the nose portion 2 is detached from the connecting band 4 and is driven into the driven material 12. At this time, the portion of the holding hole 6 of the connecting band 4 is broken within the block 7 and the fragments 13 are scattered, but at the same time as the nail driving, the air blown into the block 7 by the air blowing means is further blown into the hose 10. And
Since an air flow is generated in the hose 10, the fragments 13 are transferred by the air flow and are discharged and accumulated at a predetermined place. Since the elastic ring member 8 contacts the driven material 12, even if the posture of the nailing machine is somewhat inaccurate, the block 7 and the driven material 12 are well sealed and the air inside the block 7 Can be prevented from escaping directly to the outside. When the nose portion 2 is separated from the material 12 to be driven after the nail driving is finished, the operation of the air blowing means is also stopped.

As described above, since the fragments 13 of the connecting belt 4 can be transferred to a place different from the work site and collected and collected here, the processing becomes very easy and an accident of slipping and overturning occurs. Can be prevented.

If the block 7 itself is made of a material having elasticity to some extent, the ring member 8 at its tip may be omitted.

In the above example, air is blown into the block 7 to treat the broken pieces of the connecting band, but instead of this, an air blower is provided on the tip side of the hose so that the inside of the hose is negatively pressured for connection. The fragments of the band 4 may be sucked and transferred to a predetermined place. In this case, it is not necessary to provide an elastic ring member at the tip of the block.

[0014]

According to the first aspect of the invention, the fragments 13 of the plastic connecting band 4 generated in the block 7 are transferred to a place different from the work site by the hose 10 and are collected and collected here. As a result, the processing becomes very easy and the accident of slipping and falling can be prevented.

According to the second aspect of the present invention, since it is not necessary to provide the block 7 with the air blowing means, the operation becomes easy.
