Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a technique for transporting and storing magnetic articles, and particularly to a technique that is effective when applied to a stocker for magnetic articles such as electronic components.

[Background Art] In general, structures shown in FIGS. 1 and 2 are conceivable as a mechanism for temporarily storing electronic components such as diodes, especially electronic components having ferromagnetic lead wires.

This mechanism has a stocker 2 that holds a large number of diodes 1 having lead wires made of a pair of ferromagnetic materials in a spatial region 3 by using magnetic force, and a large number of diodes 1 are held in the central part of this switch 2. It has a structure in which the floating diodes 1N are caught in a pick-up groove 7 machined on the circumferential surface of the general feed ram 4 and taken out one by one.

That is, the stocker 2 includes a guide plate 5 made of a non-magnetic material that is vertically arranged in parallel, and a transport drum 4 that is vertically provided on the outer surface side of the guide plate 5 and is given an equal inclination to the left and right sides of the guide plate 5. A magnetic plate 6 is arranged so that the diode 1 moves and is pushed to the side, and the diode 1 that is pressed against the conveyance drum 4 in the space area 3 is placed in a take-out groove on the circumferential surface of the conveyance drum 4. 7 is taken out individually. Furthermore, the diodes in the space area 3 are replenished from the input direction 8 side by the operator's hand from the input mechanism of the previous process or from a small case in another storage box or the like. Furthermore, the inserted diode 1 is transferred to the conveyor drum 4.
Repeatedly move towards.

However, in such a stocker mechanism, the number of diodes that can be stored (charged) in the stocker 2 is small, and the oblique angle between the magnet plate 6 and the guide plate 5 is reduced.
Increasing the storage capacity by lengthening the entire length of the diode 1 causes the movement of the diode 1 in the space area 3 toward the conveyance drum 4 to be slow, and furthermore, the pressing pressure decreases, so that the diode 1 does not reach the takeout groove 7. This will lead to a significant drop in the charging rate as it will be difficult to enter. Furthermore, since there are only a few containers stored even when charging by an operator, 60 to 75 charges are required to fill the storage capacity of the stocker 2, and charging is required at short time intervals. Furthermore, when an operator charges the diode 1 by hand, the lead wire of the diode 1 is often caught and bent. Charcine is possible. Moreover, there is a risk that it may interfere with normal diodes and cause a charge trouble.

[Purpose of the Invention] Accordingly, an object of the present invention is to provide a stocker for magnetic articles that can temporarily store a large amount of magnetic articles and that can charge a large amount at one time.

Another object of the present invention is to provide a stocker for magnetic articles that can feed magnetic articles without bending them and maintain normal operating conditions without reducing the operating rate of subsequent processes.

The above and other objects and novel features of the present invention will become clear from the description of this specification and the accompanying drawings.

↑Summary of the Invention] Of the inventions disclosed in this application, one of the typical inventions is briefly described. By arranging them, it is possible to store and charge a large amount of magnetic articles.

Further, the present invention provides a variable control mechanism for the take-out port on the take-out port side of the stocker, so that the take-out [=
This avoids excessive concentration of magnetic articles in the container 1 and enables smooth transportation and storage.

[Embodiment] FIG. 3 is a schematic plan view showing an embodiment of a stocker for magnetic articles according to the present invention, FIG. 4 is a front view thereof, and FIG. 5 is a left side view thereof.

The stocker 9 for magnetic articles of this embodiment is
A guide plate 10 made of a non-magnetic material is provided vertically parallel to the guide plate 10, a magnet plate 11 as a magnetic force generating means is provided on both sides of these guide plates 100 and inclined vertically and horizontally, and this magnet plate 11 and the magnetic It consists of a yoke (a frame plate made of ferromagnetic mild steel) 12 forming a circuit.

A diode 1 as a magnetic article that is a stored item to be transported is moved into a spatial area 1 in a stocker 9 by magnetic force from a magnet plate 11.
3, they are distributed in a floating state in a certain direction.

A pair of the magnet plates 11 and a pair of yokes 12 are provided, and the vertical distance between these pairs is +iJ, as shown by Wl and W2 in FIG. It is larger than W1 (Wl<W2), and gradually approaches from the bottom to the top, and the width becomes narrower. Therefore, the diode 1 (IJI<The magnetic force between the pair of magnet plates 11 is stronger at the upper part than at the lower part, and the diode 1 tends to gather on one side -I from below in the spatial region 13.

In addition, the pair of magnet plate 11 and yoke 12 of this embodiment is also horizontally (tiltly), and Tjl between the pair is in the middle W4 on the magnetic article input side (left side in FIGS. 3 and 4). is wider than the width W3 on the take-out side (also on the right side) (W3
<w4) , they gradually approach each other in the horizontal direction from the input side to the output side, and the interval becomes narrower. Therefore, the magnetic force by the magnet plate 11 is weaker on the input side than on the output side, and the diodes 1 tend to gather from the input side to the output side.

That is, in this embodiment, the magnet plate 11 and the cork 12
The pairs gradually approach from the bottom to the top in the vertical direction and from the input side to the removal side in the horizontal direction, making rIJ narrower. diode 1
moves obliquely upward in the space area 13 from the lower part on the input side to the upper part on the unloading side as shown by the broken line arrow in FIG. form.

Furthermore, in order to receive the storage case 15 in the guide plate 10, the area below the bent portion 16 near its lower part is wide enough to accommodate the storage case 15,
The storage cases 15 inserted through the input port 17 are successively pushed out from the storage case output port 24 on the opposite side and fall.
It will be collected.

In addition, in this embodiment, in order to prevent excessive crowding of the diodes 1 in the maximum density area 14, a non-magnetic material is installed on the outlet side that is operated vertically by the motor 18 to variably control the size of the outlet. A control plate 19 (variable outlet control mechanism) is provided in the vertical direction.

The motor 18 operates at the maximum density area 14 in the stocker 9.
In order to control the overcrowding of the diodes 1 in the stocker 9, the photoelectronic detectors 2o, 21, and 22, which monitor the amount of diodes 1 stored in the stocker 9, are interlocked with each other.

Therefore, the motor 18 is connected to the photoelectronic detectors 20.2j, 2
Based on the signal from 2, the control board 19 is moved up and down to open and close the passage to the maximum density area 14, and control is performed to prevent the diodes 1 from being overcrowded in the maximum density area 14, and the diodes 1 are transferred to the transport drum 4. The diode 1 can be taken out smoothly.

Next, the operation of this embodiment will be explained.

To input the diode to the switch 9, use the input port 23.
In the vicinity, workers directly grab diodes with their hands and insert them directly from the equipment in the previous process or from a separate storage container, but once they are inserted,
At step 17, for example, the diode stored in the diode storage case 15 made of a non-magnetic material used for movement in the previous process is put into the stocker 9. A large amount of diodes can be packed in the storage case 15 with their directions aligned, and when the storage case 15 containing this large amount of diodes is inserted into the slot, the diodes in the storage case 15 will be packed in the same direction. It is taken out into the spatial region 13 by the magnetic field of 113, and since the vertical width between the pair of magnet plate 11 and yoke 12 is Wl<W2, it is once moved upward, and then the width 113 in the horizontal direction is taken out because W3<W4. Maximum concentration area 14J of diode 1, which is the maximum magnetic field area
Concentrated near f4.

The storage case 15 continuously inputs the diodes 1 from the input port 17 (on the other hand, the transport drum 4 takes out the solid diodes 1 to the outside of the stocker 9 from near the maximum density area 1.41). Depending on the number of diodes 1 stored in the space area 13, an overcrowded state may occur in the most densely packed portion 14 of the diodes, and the pressing force against the conveying drum 4 may be large, causing dumplings to be pulled by the conveying drum 4 when taken out. If the product is taken out in the same condition as before, problems will occur when supplying it to the subsequent process.

Maximum density part 14 in the above state. In order to control overcrowding near IIf4, the amount of diodes stored in the stocker 9 is monitored by photoelectronic detectors 20 to 22, and the diode detection signals from the photoelectronic detectors 20 to 22 are sent to the motor 18, which is controlled by the motor 18. By moving the plate 19 up and down to variably adjust the opening amount of the passage, the diodes flowing into the most dense portion 14 are controlled. In that case, the number of photoelectronic detectors installed may be increased to one input port.
From around 7 and 23, the amount of input can also be controlled.

In addition, the storage case 15 that is inserted through the input port 17 and the internal diode 11 is taken out by magnetic force is sequentially pushed by the subsequent storage cases that are continuously input through the insertion port 17, and the stocker 9 is removed from the stocker 9 through the output port 24. It falls and is collected.

According to this embodiment, the storage capacity can be dramatically increased by extending the magnet plate 11 and the yoke 12 vertically and tilting them vertically and horizontally.

In addition, by making it possible to insert the storage case 15, it is possible to charge the stocker 9 in large quantities at once, which greatly reduces the number of times of charging.Furthermore, since the operator does not have to handle the diodes by hand, it is possible to There is no need to bend the lead wire of the FJ.
Various troubles caused by bending of the diode lead wire during take-out using the T-equipped transport drum 4 or in subsequent processes are eliminated.

[Effects] (1)0 According to the present invention, by tilting the magnet generating means in the vertical direction, it is possible to charge a large amount of magnetic articles.

(2) Moreover, it is possible to prevent magnetic articles from excessively concentrating on the outlet and to smoothly take out the articles.
