Abstract

PURPOSE:To make it possible to independently control cylindrical containers each provided with a motion converting mechanism, by coaxially stacking the cylindrical containers while a plurality of rotary motion transmitting mechanisms being coaxially stacked onto a rotary shaft which is parallel with the axis of the cylindrical containers so that the rotary vibration is transmitted to the rotary shaft. CONSTITUTION:Rotary motion from a vibration source 19 is transmitted to a rotary shaft 18 and a clutch drive section 15. When a follower section 16 is coupled, the rotary motion is transmitted from the follower section 16 to a spiral motion shaft 12 through a rotary plate 17 and a cam follower 14 to convert the vibration motion into spiral motion to energize cylindrical containers 1 for spiral motion. When the follower section 16 is disengaged, the spiral motion is rested. With this arrangement, the cylindrical containers may be independently controlled as the whether spiral motion is applied or not.

Figure 1 is a partial cross-sectional view showing a conventional vibrating parts feeder, in which (1) is a circular container, and (2) is this circular container (1).
), (3) is the electromagnet mover attached to the mover (
Corresponding to 2), the stator of the electromagnet, (4) is the base that fixes this stator (3), and (5) is the base (4) with both ends fixed to the circular container (1). It is a leaf spring and has a certain angle with respect to the vertical direction.This leaf spring (
5) 6 to 4 are installed in a circular radial pattern.

Next, the operation will be explained. When the electromagnet is excited at a certain frequency, a circular container (1) with an n' mover (2) attached and a base (4) with a stator (3) attached.
A vertical attractive force is generated between the two and the above frequency.

At this time, since the leaf spring (5) is attached at a certain angle, the circular container (]) performs vertical movement accompanied by rotational movement. Now, this circular container (1), the transported parts and the leaf spring (5
), the vibration system resonates and generates large vibrations when the natural frequency of the vibration system matches the excitation frequency of the electromagnet. The parts to be transported are transported by vertical vibration accompanied by rotation of this circular container (1).

In order to transport multiple types of parts, this circular container (1
) are stacked on the same axis for the first time and fixed.

Conventional vibrating circular parts feeders are configured as described above, so when several circular containers are stacked to form a multi-stage system, it is not possible to drive each circular container independently. .

Furthermore, in order to drive each circular container independently, it is necessary to stack the circular containers each having a vibration source device, which has the disadvantage of increasing the size of the device.

[Summary of the invention]

This invention was made for the purpose of eliminating the above-mentioned drawbacks of the conventional products, and consists of a plurality of circular containers equipped with a conversion mechanism that converts rotational motion into helical interlocking motion, which are coaxially stacked one on top of the other. A plurality of rotary motion transmission mechanisms capable of controlling whether or not to transmit rotary motion to the conversion mechanism are installed coaxially and stacked on a rotary shaft provided in conjunction with the axis of the helical motion, and a single By applying vibration with only one rotational degree of freedom (hereinafter referred to as rotational vibration) using the vibration source device, and controlling each of the rotational motion transmission mechanisms described above, it is possible to independently control the presence or absence of spiral motion of each circular container. This is a proposal for a multiple parts feeder.

is a cam follower that is held by the nut θV and is movable up and down with respect to the nut ◇υ, and is also rotatable. (g) is a driving part of the electromagnetic clutch, and Q& is a driven part of the electromagnetic clutch, which constitutes a rotational motion transmission mechanism. α is a rotating plate that is fixed to the driven part Oe of the electromagnetic clutch and performs rotational movement with a constant valve degree within a horizontal plane.This rotating plate αη and the cam follower α◆ are connected as shown in Fig. 6. The rotational movement of the rotating plate αη causes the cam follower α to perform a rotational movement about the axis (2) of the spiral movement in the same horizontal plane. (11111 is the rotating shaft connected to the drive part α of the electromagnetic clutch, and 0 is the rotating shaft 0.
The vibration source device, which gives rotational vibrations to the Enoki, is attached to the pillar α■, and is a leaf spring for keeping the stopping position of the rotary plate 0η constant when it is stationary.

In the embodiment shown in FIG. 2, there is a circular container (1), a container part consisting of a nut 0υ and a cam follower aψ, and a drive part Q and driven part (113, rotating base) of an electromagnetic clutch.
Two of the same rotating parts are installed one on top of the other.

Next, the operation will be explained. The rotational vibration generated by the vibration source device α9 is at the rotation axis 0F! I, the rotation axis al19
The drive section 09 of the electromagnetic clutch connected to the motor rotates and vibrates. Now, if the electromagnetic clutch is controlled to connect the driving part a9 of the electromagnetic clutch and the driven part α frame, this rotational vibration will be transmitted to the rotary plate 0η connected to the driven part of the electromagnetic clutch. At this time, cam follow α → is Natsuto αI)K
On the other hand, since it is vertically movable, the cam follower Q◆ rotates in one horizontal plane around the axis of helical movement (6), and the nut α center performs a helical movement around the axis υ.
This nut O-]) is attached to a circular container (1
) also performs a spiral motion.

Also, when the electromagnetic clutch is disengaged, the rotating plate a
Since 'i5 is held at the stopped position by the leaf spring bracket attached to the support column a'3, the position of the cam follower 04゜nut θη is maintained, and therefore the vertical position of the oak (11) is also determined, and the oak iυ is stationary. However, the circular container (1) also comes to rest. From the above, by independently controlling the two electromagnetic clutches, the two circular containers can be caused to spirally move independently.

In addition, in the above-mentioned Example C, the same container part and two rotating parts are each used.
Although the ones shown are installed one on top of the other, it is not necessary to have two of them with the same sound, and any number of items of different sizes may be installed one on top of the other. Further, in the above embodiment, an electromagnetic clutch is used as the rotational motion transmission mechanism, but the present invention is not limited to this. In addition, in the above embodiment, as a conversion mechanism for converting rotational motion into helical motion,

As many rotary motion transmission mechanisms as possible are installed coaxially and overlappingly on a rotary shaft provided in conjunction with the above-mentioned shaft, and a single vibration source device applies rotational vibration to the rotary shaft. By independently controlling the presence or absence of rotational motion of a plurality of rotary motion transmission mechanisms corresponding to each circular container, it is possible to independently control the presence or absence of spiral motion of each circular container, and the device is also miniaturized. There is an effect that can be done.
