Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a magazine that stores a plurality of electronic components, and particularly relates to an improvement in the form of storing and holding electronic components within the magazine.

BACKGROUND ART Some electronic components such as capacitors are so-called chip-type devices that do not have lead wires. When such chip products are delivered or supplied to a chip mount machine during an assembly process, a certain amount of chips may be put together into a magazine.

Japanese Patent Laid-Open No. 53-23067 discloses an example of such a magazine. The magazine has a cylindrical storage space in which a plurality of electronic components are stored in an aligned stacked state, and the stored state is maintained by a stopper press-fitted into the end of the magazine. FIG. 8 shows a stopper used in this conventional example together with the chip-shaped electronic components 2 in an aligned stacked state.

In FIG. 8, the electronic component 2 is shown separated from the stopper, but in reality, the electronic component 2 is placed at a predetermined portion of the stopper while maintaining the illustrated positional relationship.
are in contact. Such a stopper is positioned by elastically pressing against the inner wall surface of the storage space of the magazine.

Problems to be Solved by the Invention The stopper shown in FIG. 8 is constructed by bending, for example, a metal plate having spring properties into a triangular shape. However, magazines equipped with such stoppers have the following problems.

Stoppers for holding electronic components in an aligned stacked state within a magazine are positioned by elastically pressing against the inner wall surface of the magazine, but such stoppers have dimensional errors during manufacturing. Sometimes. Such dimensional errors affect the force with which the stopper presses against the inner wall surface of the magazine. For example, using a magazine into which such a stopper is inserted, taking out electronic components stored in the magazine is done while moving the stopper within the magazine, but as mentioned above, dimensional errors occur and pressure welding is difficult. If the force exceeds a predetermined value, the stopper may not be able to move smoothly within the magazine. As a result, it becomes difficult to take out the electronic components. Further, if the pressure force of the stopper is too small due to this dimensional error, the stopper may fall out of the magazine during transportation.

Also, when removing electronic components from the magazine mentioned above, insert a push rod from outside the magazine.
This allows the stopper to be pushed and displaced, but the stopper as shown in Fig. 8 is
Since the contact area with such a push rod is small and the push rod is in contact with a sharp portion, the push rod may be tilted and the force from the push rod may be deviated from the center line of the magazine.

Therefore, this idea is an attempt to solve the above-mentioned technical problems.It is possible to stably store electronic components in an aligned stacked state during transportation, etc., and to ensure smooth removal of electronic components when taking them out. The present invention aims to provide a magazine that stores a plurality of electronic components.

Means for solving the problem The above-mentioned technical problem is solved as follows.
That is, the magazine according to this invention has a cylindrical storage space in which a plurality of electronic components are stored in an aligned and stacked state. One end face of the stopper, which has flat surfaces on both end faces, is placed in surface contact with the endmost electronic component in the aligned stacked state. The stopper has a pair of protrusions formed on each side thereof, and these protrusions are bent in a direction opposite to the side where the electronic component is located and are in pressure contact with the inner wall surface of the storage space, The stop is thereby positioned.

Of both end faces of the stopper forming a plane,
One end surface makes surface contact with the electronic component and provides stable holding for the electronic component, and the other end surface provides a stable contact surface for the push rod during ejection of the electronic component. Further, the projection that presses against the inner wall surface of the magazine in a bent state functions to stably position the stopper within the magazine. Further, since the projection is bent and pressed against the inner wall surface of the storage space of the magazine, the resistance accompanying the movement of the stopper can be changed depending on the direction of movement of the stopper.
That is, when the stopper moves in the opposite direction to the direction in which the projection is bent, in other words, when the stopper moves with the projection fluttering, the resistance is relatively small and the stopper can be moved with a light force.
On the other hand, when the stopper moves in the direction in which the protrusion is bent, in other words, when the stopper moves so that the tip of the protrusion scrapes the inner wall surface of the magazine, a relatively large resistance acts, and the stopper does not move as easily. cannot move. Therefore, the protrusion,
If the stopper is bent in the opposite direction to the side where the electronic components are located, the stopper can move toward the side where the electronic components are located with relatively little resistance, but it can move away from the electronic components. A relatively large resistance acts in this direction, making it difficult to move easily.

Embodiment An embodiment of the invention is shown in longitudinal section in FIG. A plurality of electronic components 2 are stored in an aligned and stacked state in a cylindrical storage space of the magazine 1, and a stopper 6a is positioned adjacent to the endmost electronic component 2. .

The details of the shape of the stopper 6a are shown in a perspective view in FIG. The stopper 6a is, for example, 6,
6-Constructed from a resin such as nylon or polypropylene. The stopper 6a has both end surfaces 6
1 and 61 are planes, and these two end surfaces 61 and 6
The side surface located between 1 and 1 has a partially constricted shape. A pair of protrusions 62 are formed that protrude outward from this constricted portion and face in opposite directions.
The protrusion 62 has a circular cross-sectional portion formed at the distal end via a relatively thin portion from the main body portion. This circular cross-sectional portion becomes a contact portion with the inner wall surface of the storage space of the magazine 1. And stoppa 6
When a is made of resin as described above, this protrusion 62 will easily bend. Stopper 6a
moves in the direction of arrow 7 within the storage space of magazine 1.

In order to obtain a magazine in the state shown in FIG. 1, for example, a method as shown in FIG. 3 or 4 is used.

For example, as shown in FIG. 3, one stopper 6a is first inserted into the magazine 1. At this time, the protrusion 62 is in a bent state, and its tip comes into pressure contact with the inner wall surface of the storage space of the magazine 1, and is positioned with respect to the magazine 1. The direction of deflection of the projection 62 is correlated to the direction of movement 8 of the stopper 6a within the magazine 1. That is, the protrusion 62 is bent in a direction opposite to the moving direction 8.

FIG. 4 shows a case where the stopper 6a has the same dimensions and shape as those shown in FIG. 3, but the dimensions (inner dimensions) of the storage space of the magazine 1 are smaller. In this case, the protrusion 62 will bend more.

As is clear from FIGS. 3 and 4, when the internal dimensions of the magazine 1 are, for example, W×H, the dimensions W×h (FIG. 2) of the stopper 6a are made slightly smaller than W and H, respectively, and the magazine 1 is It is desirable that it be easy to put in and take out the device.

As shown in FIG. 3 or 4, the stopper 6a is inserted into the magazine 1 and then moved in the moving direction 8, so that the electronic components 2 are sequentially stored behind it in an aligned and stacked state. Ru. and,
As shown in FIG. 1, when a predetermined number of electronic components 2 are inserted into the magazine 1, the electronic components 2 inserted last are contacted, for example, as shown on the right side of FIG. A stopper 6a is fitted. At this time, the projection 62 of the right stopper 6a is bent in the opposite direction to the side where the electronic component 2 is located, and is in pressure contact with the inner wall surface of the storage space. Further, the stopper that was initially inserted, that is, the stopper 6a shown on the left side in FIG. 1, is once removed from the magazine 1 and inserted again. Therefore, the direction of deflection of the protrusion 62 is opposite to the side where the electronic component 2 is located, similar to the right stopper 6a. Alternatively, the stopper 6a that was inserted first is pushed toward the side where the electronic component 2 is located, the direction of bending of the protrusion 62 is reversed, and then the other stopper 6a is pushed in.
You may insert a.

In the state shown in FIG. 1, the stopper 6
The end surfaces 61 of a are in surface contact. Further, for each stopper 6a, the direction in which the protrusion 62 is bent is such that a relatively large resistance is exerted against the direction in which the stopper 6a is removed from the magazine 1.
This will be explained with reference to FIG.

As shown in FIG. 5, move the stopper 6a() inserted into the magazine 1 toward the insertion port
When the protrusion 62 is pulled out, the stopper 6
It tries to deform as shown by a(), and eventually a force acts to reverse this and make it become as shown by stopper 6a(). Therefore, regardless of whether or not the protrusion 62 actually reverses, at least when the stopper 6a() tries to move in the direction of arrow 9, a relatively large resistance force in the direction shown by arrow 10 acts. . This resistance force is effective as a force for preventing the electronic components 2 from falling off from the magazine 1 during transportation or conveyance of the magazine 1.

When taking out the electronic component 2 from the magazine 1, one of the stoppers 6a, for example, the right stopper 6a in FIG. That's fine. Accordingly,
The electronic component 2 can be taken out from one end of the magazine 1. At this time, the left stopper 6
Since the protrusion 62 of a is bent in the opposite direction to the side where the electronic component 2 is located, it can be moved with a relatively light force. Further, one flat end surface 61 is in surface contact with the electronic component 2 at the farthest end, and a push rod (not shown) for moving the stopper 6a while preventing the electronic component 2 from tilting within the magazine 1. ) stably contacts the other end surface of the stopper 6a.

The stopper 6a mentioned above comes into contact with the inner wall surface of the magazine 1 at the tip of the projection 62. In this embodiment, since the tip of the protrusion 62 has a circular cross section, it comes into line contact with the inner wall surface. Even if there are variations in the internal dimensions of the magazine 1, this can be accommodated by the degree of deflection of the protrusion 62. Therefore, even if the internal dimensions of the magazine vary, the force required to move the stopper 6a will hardly change. Note that this force adjustment can be done by adjusting the dimensions a and
This can be done arbitrarily by changing b, c, d, and e appropriately.

6 and 7 are perspective views of stoppers used in other embodiments of this invention.

The stopper 6b shown in FIG. 6 is provided with a plurality of pairs of protrusions 62. The stopper 6b shown in FIG. The plurality of pairs of protrusions 62 are arranged side by side in the moving direction 7. According to this stopper 6b, the contact portions with the inner wall surface of the magazine are distributed in a distributed manner in the movement direction 7, so that movement within the magazine becomes more stable.

The stopper 6c in FIG. 7 is provided with a plurality of pairs of protrusions 62 along the moving direction 7, and each protrusion 62 has a knife-edge shape in cross section. Therefore, even with this stopper 6c, the protrusion 62 comes into almost linear contact with the inner wall surface of the magazine.

Furthermore, in the above description, the case where the stopper is made of resin has been described. When made of resin, it is advantageous not only in that the protrusion can be easily bent, but also in that it has an appropriate slipperiness so that it can slide smoothly against the inner wall surface of the magazine. However, such sliding can also be made smoother by, for example, coating at least one of the stopper or the inner wall surface of the magazine with a slippery resin or the like.

In addition, although chip-shaped electronic components are shown as electronic components stored in the magazine, the electronic components are not limited to this.
It may be an electronic component having lead wires.

Effects of the invention As described above, according to this invention, the plurality of electronic components in an aligned stacked state stored in the storage space of the magazine are in surface contact with the flat end surface of the stopper, so that can be stably maintained at

Furthermore, since the other end surface of the stopper is also flat, the tip of the push rod used to move the stopper and take out the electronic component can stably act on the stopper.

Furthermore, the stopper is positioned relative to the magazine by pressing the protrusions formed in pairs on each side of the stopper into pressure contact with the inner wall surface of the magazine storage space in a bent state. It can absorb variations in internal dimensions and move smoothly within the magazine with almost constant force. Therefore, it can be expected that parts can be taken out smoothly.

In addition, since the protrusion provided on the stopper is bent in the opposite direction to the side where the electronic component is located, the electronic component will try to resist the force that tries to pull it out of the magazine, and the electronic component will Falling out of the magazine is advantageously prevented. Further, when one end of the magazine is opened to take out an electronic component, it is easy to move the stopper within the magazine so as to send the electronic component toward the open end of the magazine.
