JPS61203028A - Magazine separating device for magazine stocker - Google Patents

Abstract

PURPOSE:To prevent a magazine from being shocked enabling the separated magazine to be positioned as it is by arranging an opening, through which the magazine at the lowermost stage passes through, at the lower end of a columnar guide member so as to push out the magazine located at the lowermost stage to the longitudinal direction. CONSTITUTION:A magazine 2a located at the lowermost stage is pushed out to the left by means of a pusher 6 allowing the magazine 2a to be pushed out of a cutout 3b at the lower end of a columnar guide member 3'. At this moment, if the stopper has been lowered down, the magazine can be positioned. If the pusher 6 is retracted to its original position, each of the succeeding magazines 2b-2h is lowered by one stage by its own weight allowing the magazine 2b which has been on the second stage, to be the lowermost one. This configuration enables both shock and noise to be reduced because the magazine drops from a place which is high only by the height h of one stage.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a separating device for a magazine stocker, and the present invention relates to a separating device for a magazine stocker. The present invention relates to a device for separating and positioning a lowermost magazine from subsequent magazines in a magazine stocker provided with members.

[Background of the invention]

In the industrial production of electronic components, the electronic components are transported and temporarily stored in straight-tube magazines.

FIG. 3 is a perspective view comparing the IC 1 and the magazine 2 as an example of electronic components.

FIG. 4 is an explanatory diagram showing an example of a magazine stocker, in which guide columns 3 each having a U-shaped cross section are installed vertically, and are opposed to a U-shaped recess.

Both ends of the large number of magazines 2a, 2b, 2c to 21 are fitted into the recesses of the guide columns 3, 3, and the magazines are stacked and stored. These multiple magazines are each supported approximately horizontally so that they can be lowered by their own weight.

In order to insert an IC into the lowermost magazine 2a of these many magazines 2a to 2j, or to take out an IC from the magazine 2a, the lowermost magazine 2a is separated from the following magazine 2b, This must be positioned.

FIG. 5 is a sectional view showing an example of a conventional magazine separating device. Reference numeral 3 in the figure is one of the pair of guide columns described above, and its cross section is shown. 2a is the lowest magazine, 2b is a subsequent magazine, and 2c and 2d are further subsequent magazines.

An opening 3a is provided in one part of each of the pair of guide columns 3, and a pair of bifurcated separating claws 4 (only one is shown) is pivotally supported facing the opening 3a to support the lowest magazine 2a. It is. When the separation claw 4 is rotated in the direction of arrow R from this state, the lower claw 4a that was supporting the lowest magazine 2a is removed.
drops the magazine 2a, and the upper claw 4b supports the succeeding magazine 2b. In this way, the lowest magazine 2a is placed at the position 2a shown by the imaginary line as shown by arrow A.
', it falls by a head H (however, the imaginary line 2a' depicts the state in the middle of falling).

The conventional separating device (FIG. 5) described above has a complicated structure because (a) a pair of separating claws 4 must be provided and driven in synchronization.

(b) Even if you try to reduce the noise caused by falling by the height H and receiving an impact, the height must be high enough for the separating claw to operate.)

(c) In addition to the device for separating the lowermost magazine (the component shown in FIG. 5), a means for sending out and positioning the fallen magazine must be provided. Someone has a problem.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a magazine separating device with a simple structure that can position separated magazines as they are without giving any impact to the separated magazines or causing noise. It is something to do.

[Summary of the invention]

In order to achieve the above object, the separation device of the present invention stores a large number of magazines stacked in a horizontal position, and a pair of columnar members are installed vertically to guide the magazines so that they can fall under their own weight. The lowermost magazine is slidably supported in the slider in the lowermost stage, and either an opening or a notch is provided at the lower end of at least one of the pair of column a-shaped members. The present invention is characterized in that the magazine is structured to be movable in the longitudinal direction, and that means for pushing the lowermost magazine in the longitudinal direction is provided.

[Embodiments of the invention]

Next, one embodiment of the present invention will be described with reference to FIG.

3' and 3' are guide columns constructed by applying the present invention;
A notch 3b is provided at the lower end of the guide column 3' on the left side of the figure, and a through hole 3c is provided near the lower end of the guide column 3'' on the right side of the figure.

A slide support 5. supports the lowest magazine 2a. 5 will be established.

The cutout 3b is configured to have a shape and two dimensions that allow the lowermost magazine 2a to slide along the slide support 5 to the left in the figure. A button 6 for pushing the lowermost magazine 2a to the left in the figure is provided in correspondence with the through hole 3c.

In the separation device (Fig. 2) configured as shown below,
When the lowermost magazine 2a is pushed to the left in the figure by the pusher 6, the lowermost magazine 2a is pushed out through the notch 3b and separated from the following magazine 2b, as shown in FIG.

By providing an I-flange 7 that is driven up and down as shown by the imaginary line, the lowest magazine 2a is positioned at the position shown in the figure, and it is possible to insert and store an IC in this state. Become.

Magazine 2 with IC inserted and stored in the state shown in Figure 1
In step a, the strips 1 to 7 may be retracted and further pushed to the left in the figure, or the paper may be conveyed perpendicularly to the plane of the paper. In this embodiment, the lowest magazine 2a in the position shown in FIG.
Although the IC is lowered by its own weight after being stored, with this configuration, a fixed stopper 7 is sufficient.

When the bushing 6 is restored and the lowest magazine 2a is carried out in either direction, the following magazines 2b to 2h each descend by their own weight one stage at a time, resulting in a state similar to that shown in Fig. 1, and the separation operation is completed. Complete one cycle. At this time, although the weight of the succeeding magazines falls only by the height of one magazine, they do not receive a harmful impact and there is no risk of producing significant noise.

〔Effect of the invention〕

As detailed above, when the device of the present invention is applied, it is possible to separate the lowest magazine in the magazine stocker with a simple configuration, and also to position the separated magazine on its side. This has an excellent practical effect in that there is no risk of harmful impact or noise being generated during the separation operation.
