Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a magazine for storing nails and the like in a driving machine.

FIG. 1 is a front view showing the overall structure of a conventional driving machine. In FIG. 1, the driving machine is divided into a main body 1 that performs a driving operation and a magazine 2 that stores nails. The nails in the magazine 2 are pressed against the nose 3 by a pressing force such as a spring (not shown), are placed at a driving position, and a driving operation is performed.

Conventionally, the nails stored in the magazine 2 of a driving machine are determined by the thickness of the nail body, the size of the nail head, and the size of the nail head depending on the driving member.
There are many types of nails with different lengths, and in order to perform a normal driving operation, the magazine of the driving machine must support and store the nails, so there are many types that are suitable for the nails required when driving. The disadvantage was that a magazine or driving machine had to be prepared.

FIG. 2 shows a longitudinal sectional front view of the magazine 2 shown in FIG. 1. In FIG. 2, the nail 4 is housed in the magazine 2 with the nail head 5 in contact with the nail foot 6 and the magazine 2 with a slight gap therebetween. However, in the structure shown in FIG. 2, since the magazine 2 is constantly in contact with the nail head 5, there is a drawback that the portion of the magazine 2 that comes into contact with the nail head 5 is worn out. In addition, if the size of the nail head 5 of the nail 4 is almost the same as the thickness of the nail body, or if the nail does not have a nail head 5, the nail 4 cannot be supported in the magazine 2, and the nail cannot be fed normally. It also had the serious drawback of not being able to.

FIG. 3 shows a structure that has a holding part 7 for fixing the nail head 5 of the nail 4 stored in the magazine 2. However, in the structure shown in FIG. 3, other types of nails can be loaded. In this case, the bolt 8 for fixing the presser part 7 must be loosened and then tightened at another position, which is extremely inconvenient.

FIGS. 4 and 5 are longitudinal cross-sectional views of a magazine structure that allows loading of various types of nails. In FIG. 5, the nail 4 is inserted into the gap 21 in the magazine 2 and into the kerf 22 on the periphery of the rotatable guide 13, which has a rotation center 17 coaxial with the center of the nail 4. The structure is such that a magazine cover 9 located at the top of the magazine 2 prevents the magazine from lifting up. However, in the structure shown in FIGS. 4 and 5, the rotation center 17 of the guide 13 that supports the nail 4 is coaxial with the nail, so the diameter of the guide 13 itself becomes large, and the overall size of the magazine 2 increases. This has the disadvantage of being large, and the weight of the magazine is bulky, impairing operability.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to provide a magazine for a driving machine that can store many types of nails, and to simplify the loading of other types of nails.
In addition, it is necessary to create a lightweight magazine and, in turn, a driving machine.

According to the present invention, it is possible to make the entire magazine compact by providing a rotating body that supports the nails or allows the nails to pass through the side surface of the magazine to be eccentric to the center of the row of nails. Focusing on this, the shape of the rotating body was devised so that it could accommodate many different types of nails.

The present invention will be explained below with reference to illustrated embodiments.

In FIG. 6, the magazine 2 and the nose 3 are integrated or connected by screws or the like, and are attached to a main body (not shown). Inside the magazine 2, there is a gap into which the nail should enter, a feeder 11 for feeding the nail to the injection port 14 of the nose 3, a spring 12 for pressing the feeder 11, and a spring 12 for preventing the nail from floating up. A magazine cover 9 is arranged which can be moved in the opposite direction to the nose 3 when loading nails. Furthermore, as shown in FIG. 7, a rotatable guide 13 is disposed in the magazine 2 so that any nail can be loaded therein, and is pressed toward the nose side by a guide spring 15 in the opposite direction to the nose 3. ing. At one end of the guide 13, there is an adjuster 1 that can arbitrarily select the position of the nail foot of the guide 13.
6 is fixed.

As shown in FIG. 7, the rotation center 17 of the guide 13 is arranged eccentrically from the center of the nail 4 in the magazine 2, and the cross section supports the nail foot 6 so that it can be adapted to any nail. Alternatively, it is composed of a flat part and an L-shaped part to allow the nail foot part 6 to pass through.

Next, the operation will be explained using FIG. 8, FIG. 9, and FIG. 10.

In FIG. 8, the nail 4 is inserted into the gap 21 in the magazine 2.
The nail foot 6 is inserted into the flat part 18 of the guide 13.
is grounded and pressed by a feeder (not shown). At this time, the flat portion 18 of the guide 13 is located above the rotation center 17, which is suitable for cases where the overall length of the nail 4 is short.

In FIG. 9, the nail foot 6 of the nail 4 is connected to the guide 13.
It is grounded on the flat part 19 of the L-shaped part. At this time, the flat portion 19 of the guide 13 is located below the center of rotation, and is suitable for cases where the overall length of the nail 4 is intermediate.

In FIG. 10, the nail foot 6 of the nail 4 is not in contact with the flat part 20 of the guide 13, but is in contact with the nail plate 10 housed below the magazine 2. At this time, the guide 13 serves to guide and allow the nail foot 6 to pass without supporting the nail 4, and is suitable for cases where the nail 4 is long.

FIG. 11 shows a modification of the present invention.

In FIG. 11, the nail 4 is loaded from the bottom of the magazine 2, and the guide 13 has a flat part 19 in the cylindrical part corresponding to the nail head 5 so as to prevent the nail 4 from lifting up. . In addition, the nail foot part 6
A magazine cover 9 supporting the magazine 2 is arranged so as to slide at a position below the magazine 2.

This modification has a structure in which the nails 4 can be loaded from below the magazine 2, so that the nails do not have difficulty hitting the handle and switch parts of the main body 1 shown in FIG. The distance between the machine body and the magazine can be narrowed, and the structure of the entire driving machine can be made more compact.

As described above, according to the present invention, a guide having a flat part for supporting, guiding, and passing the nails in the magazine is rotatably arranged with respect to the magazine, so that a single unit can handle many types of nails. The magazine can be loaded, and by making the center of rotation of the guide eccentric to the center of the row of nails, the guide has a flat part that does not support the nails, making the overall structure of the magazine compact and lightweight. , and can be made convenient.
