JPS5882914A - Sheet circular parts feeder - Google Patents

Abstract

PURPOSE:To provide a parts feeder comprising an oscillation bowl feeder, an oscillation rectilinear feeder and a supply position which are connected to one another by a wire in which sheet circular parts are stacked and inserted along the thickness, both end portions of the wire being supported by sleeves. CONSTITUTION:Washers 1 are inserted in a wire 5 positioned between a sleeve 6 and a sleeve 7. When oscillation feeders 2, 4 are oscillated in such a condition, the washer 1 dropping from a transport path 3 of the oscillation feeder 2 is caught by the wire 5 at a part thereof to be inserted in the wire 5 and slided along the wire 5 so as to be moved above the sleeve 6. On the other hand, at a supply position, the washer 1 is pushed by the washer 1 urged by the oscillation feeder 4 to be projected over the upper end of the sleeve 7. Whereupon, light of a projector 8 is intercepted by the washer 1, and when a photo detector 9 detects that the washer 1 is supplied, the oscillation feeder 4 is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device for thin plate annular parts, particularly for feeding thin washers and the like.

Conventionally, a ball-shaped vibrating feeder and a linear vibrating feeder were installed as a device for feeding washers etc. one by one, and the washer was separated one by one by the ball-shaped vibrating feeder and then fed by the linear vibrating feeder. There is a device that arranges the materials in a line and feeds them to the desired position, and then takes out the materials one by one from the end using a pick-and-place unit or the like. However, in such a device, the transfer path of a linear vibratory feeder requires a certain gap between the thickness of the washer and the height of the transfer path, and as the washer becomes thinner, the transfer path becomes smaller. There is a drawback that washers may overlap within the container, making it impossible to transport them. Therefore, when the thickness of the workpiece was about 13 mm, the automatic feeding system became inactive and the sheet had to be fed by one person, resulting in poor workability.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a feeding device that makes it possible to automatically feed thin plate annular parts.

In order to achieve the above object, one aspect of the present invention is as follows.

The ball-shaped vibratory feeder, the linear vibratory feeder, and the supply position are connected by a wire inserted into the thin plate annular component stacked in the thickness direction, and both ends of this wire are loosely fitted around the outer diameter of the thin plate annular component. To support. It is characterized by being supported by a guide.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 to 4 show one embodiment of the present invention, so
In the figure, 1 is a washer formed with a plate thickness t, an outer diameter, and an inner diameter d. Reference numeral 2 is a ball-shaped vibrating feeder, which transports the washers 1 along a transport path 5 and drops them one by one from the end of the transport path 3 toward the bottom. Reference numeral 4 is a linear vibration feeder which feeds the washer 1 in the direction of arrow A. Reference numeral 5 is a wire having a diameter smaller than the inner diameter d of the washer 1, and the washer 1 is inserted in a stacked manner in the direction of the plate thickness.

One end of the wire 5 is attached to a washer 1 inserted into the wire 5.
is supported by a sleeve 6 that is slidably fitted loosely,
The other end is also supported by the sleeve 7 in the supply position. Furthermore, the end of the vibrating feeder 21111 of the wire 5 is located in the fall path of the washer 1, which is lowered from the transfer path 3 to the bottom of the vibrating feeder 2, so that the washer 1, which is lowered from the transfer path, is inserted into the wire 5. It has become. Note that the probability that the washer 1 is present on the wire 5 changes depending on the position of the tip of the wire 5, so it can be set arbitrarily.

The outer periphery of the washer 1 inserted into the wire 5 is in contact with the vibrating feeder 4, and a transfer force toward the feeding position tK is applied thereto.

Reference numeral 6 indicates a light emitter, and reference numeral 9 indicates a light receiver, which are arranged so as to face each other with the sleeve 7 in between, so that when the washer 1 protrudes from the upper end surface of the sleeve 7, it is detected. Reference numeral 10 is a chuck, which is fastened to a big-and-place unit 11 and holds the washer 1 in layers 9&. A product 12 is transported to a predetermined assembly position by a transport device 13 and positioned by a positioning unit 14 .

In the above configuration, the washer 1 is inserted into the wire 5 located between the sleeve 6 and the sleeve 7. When the vibration feeder 2.4 is vibrated in this state, the vibration feeder 2.
A part of the washer 1 falling from the transfer path 3 is caught on the wire 5, inserted into the wire 5, and moves the wire 5 above the sliding sleeve 6. On the other hand, at the supply position, the washer 1 is pushed by the washer 1 urged by the vibration feeder 4, and the washer 1 protrudes from the upper end of the sleeve 7. Then, the floodlight 8
The light is blocked by the washer 1, and the light receiver 9 detects that the washer 1 is supplied. Then, the vibrating feeder 4 stops.

On the other hand, when the product 12 is positioned at the assembly position, the bi-quard place unit 11 is activated, and the washer 1 in the supply position is taken out by the chuck 10 and assembled onto the product 12.

Then, the light receiving WF9 opens and receives the light from the projector 8, and the vibration feeder 4 is activated.

As described above, according to the present invention, the ball-shaped vibratory feeder, the linear vibratory feeder, and the feeding position are connected by a wire inserted into the thin plate annular component stacked in the thickness direction of the thin plate, and both ends of this wire are connected to the thin plate annular component. The outer diameter of the annular part is supported by a guide that loosely fits, so even if the washer is thin,
This has the effect of ensuring reliable transfer and supply.
