In the above configuration, the first counter weight aO, the electromagnet qυ fixed thereto, etc. vibrate integrally and constitute a movable mass on the first counter weight side,
Similarly, the electromagnets (221, etc.) fixed to the second counterweight (2D1 vibrate integrally and constitute a movable mass on the second counterweight side, but the vibration isolation plates (20a) (20b) and (31a) (31b) 1st counter way) 09 and 2nd counter way
The fixing points to the weights (2il) are determined to be above the center of gravity of the first counter weight side movable total mass and the center of gravity position F of the second counter weight side movable total mass. In the example, the first trough (
1) and the second trough (2) are made of aluminum, and the total movable mass on the first and second counter weight sides is mostly made of iron, so the first trough (υ or the second trough (2)
The center of gravity position of the movable total mass on the first trough side or the second trough side, which is also included in 4, is close to the center of gravity position of the movable total mass on the first or second counter weight side, and is located only slightly above. However, the first trough (υ, the second trough (
2) Although it is made of steel, if the total mass of the parts to be accommodated is large, the overall center of gravity will be high, so depending on the case, vibration isolating plates (20a x 20b) and (31a)

The fixing point to (21) may be set higher than the entire center of gravity including the first and second troughs (1) and (2).

In short, in this embodiment, the fixed point is set at a position that is higher than the center of gravity of the total movable masses on the first and second counter sides by at least ρ.

The embodiment of the present invention is constructed as described above, and its operation will be explained next.

When alternating current is applied to the coils (6) (c), an alternating attractive force is generated between the electromagnet 9υ@ and the movable core a3 (2), and the first trough (1) and the second trough (2) In FIG. 2, it vibrates in the directions shown by arrow a and dotted arrow s.

be done. That is, the parts in the first trough (1) rise above the transfer surface (7), and when they reach the terminal end (3b), they move along this guide surface to the starting end (4a) of the second trough (2). The transfer surface (8) of the second trough (2) then rises in the direction indicated by the full arrow.Upon reaching the terminal end (4b), the parts with their longitudinal direction facing the transfer direction remain in the supply trough. (
6), but the laterally oriented parts slide down the slope (9) completely and end up at the starting end (3) of the first trough (1).
a). Thereafter, parts that are not sorted are circulated through the first trough (1) and the second trough (2) in the same manner. The sorted parts are supplied one by one to the next process from the discharge end of the groove (5) of the supply trough (6).

The first trough (1) and the second trough (2) vibrate in opposite phases, and the reaction force due to these vibrations is generated by the resonance plate (14a).
(14b) and (25a and 25b) i are transmitted to the first counter weight αQ and the second counter weight (211), respectively. , second trough (
It vibrates in the same direction as 11(2), but the amplitude is much smaller. That is, the resonance plates (14a and 14b) and (25a and
The spring constant of the bar 25b) is determined, but the bounce constant of the vibration isolation plate (2ga) (2Ub) and (31a) (31b) is determined in consideration of the vibration isolation effect. It is. The first counter weight q0 and the second counter weight q0
Since the weights D vibrate in opposite phases, the horizontal components of the reaction forces transmitted to the base block (to) (29) cancel and cancel each other out, so only the slight force of the difference is transmitted to the base block Qal4. Ru. Although the vertical components are phase-added, the amplitudes of the first and second counter weights αq circle are much smaller than those of the first and second troughs (1) and (2), so the base block (trough) is ) is also very small.

As mentioned above, the first trough (IJ) and the second trough (2
) is completely independent, in other words, it vibrates without being affected by the vibration of the other, so the width of both troughs (IJ (2)) that is performed when using this linear parts feeder is This adjustment can be made extremely easily by independently controlling the amount of current flowing through the coils (6) (c).

In addition, the vibration isolating plates (20a bar 20 and (31a bar 31)
b) 1st and 2nd counter weights) QO (211) are fixed to the weight α0 (2V and electromagnet αυ (24, etc.), respectively, above the center of gravity of the movable total mass on the 1st and 2nd counter weight sides. Therefore, as shown in Figures 3 and 4, the first trough (υ) and the second trough (2
) produces stable and uniform vibrations. For example, in a conventional linear parts feeder, the vibration angle at the tip of the supply trough (6) is very horizontal, and the present invention is not limited to this, but is based on the technical idea of the present invention. Various modifications are possible.

For example, in the embodiments described above, the inclined surface (9) is used as the simplest part sorting means, but the present invention is not limited to this, and various known means can be applied.

Further, although plate springs are used as the resonance elastic means and the vibration isolation elastic means, other elastic means such as rubber springs may be used.

As described above, according to the linear parts feeder of the present invention, the amplitude of the first trough and the second trough can be completely adjusted to the valley of the driving force of the first vibration @ drive section and the second vibration drive section. The desired adjustment to the valley trough is extremely easy since it can be adjusted independently, ie without any influence on the other party.
