Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a magazine for storing a fastener assembly in which connected nails, screws, etc. are spirally wound.

FIG. 1 shows an overall view of a prior art driving machine as a general type of fastening machine, and FIG. 2 is a sectional view showing only the magazine portion thereof.

To explain the prior art magazine shown in FIG. 2, a magazine 2 formed in a substantially cylindrical shape has a bottom cover 3 rotatably connected at one end to the lower part of the magazine 2, and only when a fastener assembly 8 is loaded. This part is opened, and the lower part of the magazine 2 is normally closed by a bottom cover 3. Further, a saucer 4 that is vertically slidable and rotatable is attached to the bottom lid 3 side, and the saucer 4 is always pushed upward by a spring 5 inserted into the saucer protrusion 6.

The spirally wound fastener assembly 8 is stored in a magazine as shown in FIG.
The saucer 4 moves up and down depending on the length of the fastener assembly 8, and the fastener assembly 8 is always located above. The structure is such that it is pulled out and fed into the main body.

Therefore, the prior art has the following drawbacks. That is, as described above, the receiving tray 4 is pressed onto the fastener assembly 8 by the spring 5, and the fasteners are supplied by pulling out the outermost winding end of the fastener assembly 8. Therefore, during use, the receiving tray 4 is , rotation, vibration, etc. Therefore, the saucer protrusion 6 wears out prematurely and separates from the saucer 4, so that the upper part of the spring 5 no longer holds the saucer and does not perform its original function.

The purpose of the present invention is to maintain the function of the tray of this type of magazine for a long time without causing any hindrance to the movement of the tray, which has the drawbacks mentioned above.

In the present invention, the shape of the spring is devised so that the point of action of the spring force that pushes up the saucer is away from the parts that are prone to wear, and also so as not to interfere with the rotational movement of the saucer.

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

In FIG. 3, the magazine 2 has a substantially cylindrical shape with a closed top end and has an opening for pulling out fasteners on a part of the side surface. At the bottom thereof, there is a dish-shaped bottom lid 3 whose one end is rotatably connected to the magazine 2. The lower part of the magazine 2 is always closed due to the bottom cover 3. Further, a saucer 4 that is vertically slidable and rotatable is attached to the bottom lid 3 side, and the saucer 4 is always pushed upward by a spring 5.

Note that the shape of this spring 5 is
The inner diameter of the upper end of the spring and the shaft are made as narrow as possible to reduce the play between the upper end of the spring and the shaft 9. It is molded so that the difference in diameter from 9 is as large as possible.

According to the present invention, in the magazine of this type of fastener, the winding diameter of the terminal end of the spring that normally pushes up the catch plate is increased, so that the rotation of the catch plate when pulling out the fastener is not hindered. The spring does not easily separate from the saucer even if the saucer protrusion wears out, and as a result, the life of the saucer can be improved.

[Brief explanation of the drawing]

Fig. 1 is an overall view showing an example of a fastening machine according to the prior art and a side view thereof, Fig. 2 is a longitudinal cross-sectional side view of the magazine section of Fig. 1, and Fig. 3 is an implementation of the magazine of the fastening machine according to the present invention. This is an example of a vertical side view. In the figure, 2 is a magazine, 3 is a bottom cover, 4 is a saucer, 5 is a spring, 6 is a saucer protrusion, 8 is a fastener assembly, 9 is a shaft, 11 is an opening, 51
is the middle part of the spring.

Claims (1)

[Scope of utility model registration request] A magazine structure for a fastening machine that stores a fastener assembly formed by spirally connecting fasteners with their axes substantially parallel to each other, wherein an opening is formed in a side surface of the magazine to sequentially draw out the fasteners. A bottom cover is attached to the bottom portion to cover an insertion opening into which the fastener assembly is loaded, and a receiving tray for supporting the fastener assembly is attached to the inside of the bottom cover so as to be movable up and down,
A spring is disposed between the saucer and the bottom lid, and is wound around a shaft installed in the bottom lid to urge the saucer upward. A magazine structure characterized by having a small diameter and being formed into an almost pouch-like shape.
