Abstract

PURPOSE:To make it possible to independently control containers as to whether spiral motion is applied or not, by coaxialy stacking cylindrical containers each having a rotary motion transmitting mechanism and a motion converting mechanism, and as well by applying rotary vibration thereto from a single vibration source so that the rotary motion transmitting mechanism is controlled. CONSTITUTION:Rotary vibration from a vibration source 16 is transmitted to an electromagnetic clutch drive section 14. When a drive part 14 and a follower section 13 are coupled together so that a spline shaft 12 performs rotary vibration, and therefore, a spiral motion cylinder 11 carries out, spiral motion to energize a cylindrical container 1 for spiral motion. When the electromagnetic clutch is disengaged, the follower section 13 maintains its stationary condition so that the cylindrical container 1 is made static. With this arrangement containers may be controlled, independently from each other.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multiplex parts feeder having a plurality of vibrating parts feeders.

[Prior art]

Figure 1 is a partial cross-sectional view showing a conventional vibrating parts feeder. In the figure, 1) is a circular container, (2) is an electromagnetic mover attached to the circular container (1), and (3) is a circular container. is the electromagnetic stator corresponding to this stator (2), (4) is the base that fixes this stator (3), and (5) is this base (4).
) and the circular container fil, each of which has its both ends fixed, has a certain angle with respect to the vertical direction. Six or four of these plate blades (5) are installed in a circular shape.

Next, the operation will be explained. When the electromagnet is excited at a certain frequency, a vertical attraction is created at the above frequency between the circular container rll to which the mover (21) is attached and the base (4) to which the stator (3) is attached. A force is generated.At this time, the circular container (1) moves up and down with rotational movement because the leaf spring (5) is attached at a certain angle. A circular container (II), the transported parts and a leaf spring (5) placed in this circular container (1)
), the vibration system will resonate and generate large vibrations if the natural frequency of the vibration system matches the excitation frequency of the electromagnet. That is, the parts to be transported are transported by vertical vibration accompanied by rotation of this circular container (]l.

In order to convey a plurality of types of parts using the above-mentioned vibrating parts feeder, a plurality of circular containers (II) may be stacked and fixed coaxially in nine vertical directions.

However, because the conventional monkey motion circular parts feeder is configured as described above, when multiple circular containers are stacked to form a multi-stage system, it is not possible to drive each circular container independently. .

In addition, in order to drive each circular container independently,
It is necessary to stack circular containers each equipped with a shaker TmI# device, which has the disadvantage that the device becomes larger.

[Summary of the invention]

This development 8Afi was made to eliminate the drawbacks of the conventional ones as described above, and includes a rotary motion transmission mechanism that can control whether or not rotary motion is transmitted, and a conversion that converts the transmitted rotary motion into helical motion. A plurality of circular containers equipped with a mechanism are placed one on top of the other on the same axis that can rotate, and a single vibration source device is attached to this axis to generate vibrations with only one rotational degree of freedom (hereinafter referred to as rotational vibrations). ), and the object of the present invention is to provide a multiple parts feeder that can independently control the presence or absence of spiral motion of each circular container by controlling a stone rotational motion transmission mechanism provided in each circular container.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure and FIG. 6, (11 is a circular container, αυ is a helical movement tube fixed to this circular container (11, and has a male thread on the outer surface and a spline nut on the inside), and 0a is this helical movement tube. A spline shaft that meshes with αυ and transmits rotational motion, (13 is a driven part of an electromagnetic clutch connected to this spline shaft 11Z, (141 is a city, a drive part of a magnetic clutch, ft5) is a drive part of this electromagnetic clutch. The connected and rotating shaft, tIe, is a vibration source device k, ft7 that gives rotational vibration to 151, is a column, (the country has a female screw that is fixed to this column and meshes with the male screw of the spiral movement cylinder αυ). The fixing nut 117 is a leaf spring that is attached to the upper support column 117 and is used to keep the driven part 131 of the electromagnetic clutch at a constant position when it is at rest.

Figure 2 shows the circular container (11), the spiral cylinder (lυ,
Spline shaft uz, ig magnetic cutter uL (141,
Two containers of the same type each consisting of a fixing nut +116 and a leaf spring Ill are placed one on top of the other around an axis 09.

Next, the operation will be explained. The rotational vibration generated by the vibration source device t+61 is transmitted to the shaft +151, and the shaft (the driving part 114 of the electromagnetic clutch connected to 19) rotates and vibrates.

Now, control the electromagnetic clutch to connect the driving part (1) and the driven part (0).
:1 is connected, this rotational vibration is transmitted to the spline shaft (12) connected to the driven part +13 of the electromagnetic clutch.At this time, the inner side meshes with this spline shaft uz, and the outer side is fixed to the support column a7. Fixed nut full
The helical movement cylinder (■υ) engaged with the helical movement cylinder (■υ makes a helical movement by 1υ), and the circular container (1) attached to the helical movement cylinder (■υ) also makes a helical movement. When the electromagnetic clutch driven part Q3
is held in a stationary position by a leaf spring (I9) taken from the strut (inK), so that the static position tIIt of the spline shaft (12) and the helical movement cylinder aυ is maintained, and therefore the upper and lower necks of the helical movement cylinder aυ Also, the spiral motion cylinder 0υ
comes to rest, and the circular container (1) also comes to rest.

From what I have explained above, there are two 1s! By independently controlling the L magnetic clutches, the two circular containers can be spirally moved independently.

In addition, in the above example, two identical containers are installed one on top of the other, but it is not necessary that there are two identical containers, and it is possible to set up how many containers of different sizes are installed one on top of the other. Good too. 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.

〔Effect of the invention〕

As explained above, according to the present invention, a plurality of circular-shaped Since the containers are installed on the same axis and this axis is connected to a single vibration source device that generates rotational vibrations on this axis, multiple power transmissions corresponding to multiple circular containers are possible. By independently controlling the presence or absence of power transmission of the mechanism, it is possible to independently control the presence or absence of spiral movement of each circular container, and it is also possible to miniaturize the device.
