Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a spring storage magazine that can store a large number of conical coil springs used as trip springs for electromagnetic contactors, electromagnetic relays, and the like.

[Prior Art] As approximations and devices become smaller and more sophisticated, the shape of coil springs has come to be not only cylindrical, but also cylindrical, cylindrical, barrel-shaped, and conical.

Therefore, if a plurality of coil springs having these shapes are packed in a box, they become more intertwined with each other in the box than before, and it is time-consuming and inconvenient to take them out one by one for use.

For this reason, packaging materials that individually store coil springs and allow easy removal have been considered.

Fig. 8 is a perspective view showing a conventional packaging material disclosed in, for example, Japanese Utility Model Application Publication No. 58-29979, Fig. 9 is an enlarged vertical side view showing the main parts of the packaging material, and Fig. 10 is the same packaging material. FIG.

In the figure, reference numeral 1 denotes a flexible belt-shaped sheet made of synthetic resin or the like, and between both ends of the sheet 1 there are many parallel article storage grooves each having an opening 2 at the top with a width smaller than the diameter of the stored article. Furthermore, engagement protrusions 4 are provided at both ends of each storage groove 3 to prevent articles from slipping out of the storage groove 3.

In the illustrated case, the engaging protrusion 4 is provided protruding from the inner periphery of the storage groove 3 by heating embossing, but it may also be formed by a piece extending from the edge of the storage groove 3.

Moreover, the above-mentioned storage groove 3 is formed into a C-shaped cross section by heating embossing.

Further, on the inner periphery of the storage groove 3 near the opening 2, a presser projection 5 is provided to prevent the article from shifting.

The conventional packaging material is constructed as described above. For example, in order to package the coil spring a with the packaging material, the opening 2 is expanded by pulling both ends of the sheet 1, and then the storage groove is inserted through the opening 2. 3
Insert coil spring a.

Thereafter, by releasing the tension on both ends of the sheet 1, the enlarged opening 2 returns to its original width.

Alternatively, the coil spring a may be placed on the opening 2 and pushed into the storage groove 3.

Next, to take out the stored coil spring a, either forcefully push out the coil spring a from the bottom of the storage groove 3 toward the opening 2, or expand the width of the opening 2 by pulling both ends of the sheet 1. By expanding it, the coil spring a can be taken out from the storage groove 3.

[Problems to be Solved by the Invention] The conventional packaging material as described above is configured as a flexible sheet 1 in which article storage grooves 3 having openings 2 having a width smaller than the diameter of the article are formed in parallel at the upper part. Therefore, if a conical coil spring with greatly different diameters is stored in the article storage groove 3, one end of the conical coil spring will be stored in the article storage groove 3. There was a problem that it would jump out of groove 3.

Another problem is that since the coil springs a are individually stored at their natural length, the volume is considerably larger than the volume of a package containing multiple coil springs, which increases transportation costs. It was hot too.

This invention was made in order to solve this problem, and even if the shape of the coil spring is not only cylindrical but also has a large difference in diameter at both ends such as a conical coil spring, it can be stored individually. The objective is to provide a spring storage magazine that is easy to take out, can prevent stored coil springs from falling out, and can store coil springs individually in a compressed state, making the volume considerably smaller than conventional examples. shall be.

[Means for Solving the Problems] The spring storage magazine according to the present invention has a plurality of magazine grooves provided on the upper and lower surfaces of the through hole penetrating in the width direction, and a plurality of magazine grooves provided at a predetermined interval in the longitudinal direction on the upper edge of one side. A rectangular storage magazine body that is movable in the longitudinal direction and has a plurality of magazine notches separated by a side wall of the magazine notch, and a magazine body that has a plurality of magazine notches separated by a magazine notch of a constant width. There is a magazine stopper that intermittently stops the storage magazine body that moves by contacting the side wall of the magazine notch when advancing, and a coil spring is compressed in the magazine groove of the storage magazine body stopped by the magazine stopper. The spring pushing mechanism includes a spring holding member, a spring compression member that advances and retreats toward the spring holding member, and a coil spring that is held in a compressed state by the spring holding member and the spring compression member. and a push rod that pushes the magazine toward the magazine groove.

[Function] In this invention, when the magazine stopper advances into the magazine notch of the moving rectangular storage magazine body, the magazine stopper closes the magazine notch that partitions the magazine notch of the storage magazine body. Stops the storage magazine body by coming into contact with the side wall. When the storage magazine body stops, the spring pushing mechanism operates, and the spring holding member and spring compression member hold the coil spring in a compressed state.
A push rod pushes the coil spring into the magazine groove, and the coil spring is individually stored in the magazine groove in a compressed state. A large number of coil springs can be stored in a large number of magazine grooves by operating the spring pushing mechanism every time the moving storage magazine body is stopped by the magazine stopper.

In addition, when taking out the coil spring stored in the magazine groove of the storage magazine main body, the push rod of the spring pushing mechanism is operated against the storage magazine main body that is stopped by the magazine stopper, and the spring is pushed in. By increasing the amount by which the rod is fed out, the coil spring stored in the magazine groove can be taken out to the outside.

In addition, when taking out the conical coil springs stored in the plurality of magazine grooves 2, the magazine stopper 11 of the spring supply machine and the push rod 14 of the spring push mechanism 10 are used to increase the amount of movement of the push rod 14. This can be carried out using the same procedure as when storing the conical coil spring 3 in the magazine groove 2.

Although this embodiment has been described using the conical coil spring 3 as the coil spring, the invention is not limited to this, and it goes without saying that the present invention can also be applied to coil springs in the shape of a string, a barrel, or a cylinder.

[Effects of the Invention] As explained above, the present invention has a plurality of magazine grooves provided through the width direction and a plurality of magazine notches provided at a predetermined interval in the longitudinal direction on the upper edge of one side. A magazine stopper extending toward the magazine notch contacts a side wall of the magazine notch that partitions the magazine notch, and the magazine is stored in a rectangular shape that is moved in the longitudinal direction. When the magazine body is stopped, the spring pushing mechanism operates, and the spring holding member and the spring compression member hold the coil spring in a compressed state, and the pushing rod pushes the coil spring into the magazine groove. The coil spring is stored in a compressed state, and the push rod of the spring push mechanism is advanced into the main body of the storage magazine, which is stopped by the magazine stopper, and the removal of the coil spring is stopped by the magazine stopper, and the amount of payout of the push rod is increased. By doing this, the coil springs stored in the magazine storage groove can be taken out to the outside, so a large number of coil springs can be stored in the storage magazine body in a compressed state, and the coil springs can be stored in a compressed state. This prevents the stored coil spring from coming out, and the magazine stopper and spring pushing mechanism operate to easily store and take out the coil spring without manual effort. Since the coil spring is housed in the magazine groove, the volume of the spring housing magazine can be made considerably smaller than in the past, and transportation costs can also be reduced.
