Next, a method of manufacturing the equal distribution block C (υ) specified in the 4th A(9) to the 4th CIJ will be explained.

The first body (1), the second body (2), and the ring plate (1) are made of aluminum, for example, but the equal distribution block (31) is also made of aluminum. Real cylindrical aluminum block (30
1 should be prepared. A hole (30a) in the shape of an inverted truncated cone is machined on the upper surface of this block side, for example, using a lathe. As a result, the hole is machined into the shape shown in FIGS. 3A and 3B, but the upper edge of the hole (30a) coincides with the outer periphery of the block.

Next, a plane (33

Furthermore, there is a groove parallel to the chord V on the bottom surface of the block 01)4)
is cut to a predetermined width and depth, and thus the fourth B
As shown in FIG. 4 and FIG. 4C, a pair of vertical guide portions 05) to the cutting feeder are formed.

As shown in FIGS. 7 and 8, the equal distribution block 01) processed as described above has a cylindrical hole (431K tightly fitted) in the second body (end) at its arcuate peripheral side. , second
The slideway portion (33aX33b) has cutout grooves (42a) (42b

IJ″f: Vibration R11 product supply device 6 with the above-mentioned configuration
The effect of this will be explained.

At the time of small scale illiteration [2, a large amount of electronic components, such as chip capacitors, are put into a hopper (11), and as shown in FIG.
A) is reached in 1, but now the parts are the first body of the hopper (υ) (
It is assumed that up to 44 parts are stored.

When the electromagnetic feeders (7) and (8) for cutting are driven.

The parts on the troughs (7a) and (8a) are transferred to the right in FIGS.
Parts from J are discharged into troughs (7a) and (8a). Parts in hopper <1 are discharged along arrows A, N, A, but there is an upward horizontal line in the passage. Since there are no surfaces, all surfaces are downwardly sloped, and the discharge passages are configured symmetrically with respect to the Lht of the equal distribution block (31), the parts flow smoothly and evenly. A discharge port portion (60a) formed by the lower end portion of the second main body (36) and the guide portion 13ω of the equal distribution block Oυ
(60b) and 70) are discharged into the troughs (7a) and (8a). Furthermore, this discharge action is applied to the equal distribution block (3υ) from the upper part of the first slideway part (32a).
The parts that reached (32b) are the first slide section (32a) (32
b) The parts are equally distributed on the left and right sides of the ridge line t, receiving a transfer force toward the trench line t located on the center line between It slides down toward the discharge port section C, 60a) (60b) at the same speed. Therefore, the parts are fed from the hopper (1) to the troughs (7a) and (8a) in equal amounts, and the electromagnetic feeders (7) and (8) feed the parts at a constant speed. (Supplied to the electromagnetic feeder (6). As mentioned above, the drive signal of the empty detector 0$OG installed above the parts feeder Uυ (6)
7) (8) starts to drive, but either the empty detector α uniform aQ sufficiently detects that parts are fed into the balls of the parts feeder QvQ■, or a drive signal is generated and ηλ After a predetermined time has elapsed, the drive signal disappears and the electromagnetic feeders (7) and (8) stop. The parts supplied to the parts feeder aUa are transported clockwise and counterclockwise along the track (11 (14)), and their posture is corrected by each conveying means (not shown) and then supplied to the supply electromagnetic feeder α. Parts are supplied from the -10,000 groove (261) of the trough (19a) of the electromagnetic feeder 01, and the other groove (27) is supplied with parts from the other parts feeder (B). Parts are supplied, respectively Fig. 1 and 8rrJ
In Figure 2, it is moved to the right. When the Tl1 product becomes over 7o- on the groove □□□ (2η), this is detected by the 0 stage overflow detector (17), and the parts feeder (6) is stopped by this detection force. Groove (2G+ (2V) discharge end (26a bar 27a)
71. Each piece is supplied to the next process.

As described above, the parts feeder Qυ (b) is supplied with parts from the cutting electromagnetic feeders (7) and (8) according to the detection signal of the empty detector α0 (a). Components can be supplied into the balls of Nos. 11 and 102 at the minimum necessary density or storage amount, and therefore the number of times the components are circulated within the balls can be reduced as much as possible. That is, track Q: riαΦ
The parts that are not sorted by the parts sorting means at the top are dropped to the center of the ball or to the lower track part,
The track 0 peak α4) t rises again and is subjected to the sorting action by the parts sorting means, but the higher the density of parts in the ball, the more times the parts will fall and be transferred again to the loading means. will increase. Since it is necessary to strictly control the characteristics of electronic components, track (to) (14)
- It is not good for the case to be repeatedly transported and subjected to friction and to be dropped from the truck many times. However, according to this embodiment, an empty detector O (11P) is placed above the ball.
Electromagnetic feeder for cutting with gold (7) (8) 71
・Since the supply of these materials is limited, it is possible to reduce the density of parts inside the pole as much as possible, and therefore the properties of the parts can be preserved to that extent. In particular, in this example, since the hopper (1), which can smoothly discharge parts evenly, is small, the parts are fed equally from the electromagnetic feeders (7) and (8) to the parts feeder (1η0 seconds). Therefore,
The parts feeder assistant (6) can be operated efficiently under the above conditions. If the parts are not evenly supplied to the parts feeder (II) (12'), the overflow detector C23 shear on the supply electromagnetic feeder will move at completely different timings, and the parts feeder υ or (2) will move at completely different timings.
would have to be stopped at completely different times. This reduces the component supply efficiency of the supply electromagnetic feeder. However, according to this embodiment, the parts are evenly and efficiently supplied from the hopper (IJ) to the cutting electromagnetic feeders (7) and (8), so that the cutting electromagnetic feeders (7) and (8) are fed at ideal timing. (-da(7) (+1).

The parts feeder (II, l Qa'lc) can be operated, thereby improving the parts feeding efficiency of the feeding electromagnetic feeder (U) while guaranteeing the characteristics of the parts.

The number of parts in the hopper (1) decreases as the electromagnetic feeder (7, 1 (8)) cuts out parts, but the number of parts in the hopper (1) decreases.
Since the discharge passages for the parts inside are completely symmetrical with respect to the branch line t, they are equal on the left and right sides of the branch line t, and as it decreases, an equally distributed action is guaranteed until the end 6. All the surfaces in the hopper (1) are facing downwards, and since there are no horizontal surfaces that could stagnate parts, it is completely empty. So the parts are J-non-issued.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiments, etc. Using a hopper with a distribution block (3I),
Although the two discharge ports discharge parts evenly and until they are completely emptied, it is also possible to use a hopper that simply has two discharge ports.

In addition, an electromagnetic vibrating feeder (
7) and (8) were used, but other drive types of feeders may be used.

In one or more embodiments, the 15B product is fed to the next process continuously from the grooves (27a) and (27b) of the feed vibrating feeder a, but a stopper is generally installed at the discharge end of these feeders. After stopping all the parts at this point, for example, all the parts may be suctioned by a vacuum suction device and then supplied to the next process.

As described above, although the vibrating parts feeder of the present invention uses two vibrating parts feeders, the total installation or setting area for the entire loading process can be reduced by a wide range of υ compared to the conventional method. In addition, since only one hopper is required, equipment costs can be reduced.
