DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The component supply apparatus of the present invention will be described in detail below with reference to FIGS. The apparatus of the present invention is one in which two return type feeders are combined into one, and the trough for conveying the parts is the central trough 1 for conveying the parts toward the discharge chute 2 and the direction for the parts opposite to the central trough. Carry to 2
It consists of two side troughs 4 and 5, the weight of the central trough being equal to the sum of the weights of the two side troughs.

A central wall 1a for partitioning two feeders is provided in the central longitudinal direction of the central trough 1, and two steps of progressive tracks 6a, 6b, 7 are provided on both sides of the central wall 1a.
a and 7b are formed, and these progressive trucks have an ascending slope in the direction of the discharge chute 2 (rightward in FIG. 1).

Between the upper progressive trucks 6a and 7a and the discharge chute 2, there is provided an aligning section 3 for arranging the parts moving on the progressive truck in a line. It is composed of an escape plate 3a and an aligning plate 3b straddling the central wall 1a of the central trough 1.

The escape plate 3a is provided with blades 3c and 3c whose width becomes narrower toward the discharge chute 2, and when the parts enter from the progressive trucks 6a and 7a in two rows, the central wall is provided. Only the parts that move along the la 1a are passed to the discharge chute 2 side, and the other parts are dropped to the lower-stage progressive trucks 6b and 7b. Further, even when the discharge chute 2 is full of parts, the parts are overflowed and dropped onto the lower-stage progressive trucks 6b and 7b.

The alignment plate 3b is provided to determine the position and directionality of the components that have passed through the escape plate 3a and are arranged in a line. Since there are various known components depending on the type and shape of the components to be supplied, the description thereof will be omitted. To do. If it is desired to change the type or size of the parts to be supplied, the aligning section 3 is appropriately replaced.

Side walls 4a and 5a are provided on the outer edges of the side troughs 4 and 5 so as to prevent the parts from falling off, and two upper and lower reverse feed tracks 8a, 8b, 9a and 9b are formed inside thereof. There is.

This reverse feeding truck has a slope ascending to the left in the drawing from the discharge chute 2 side, and the deepest portions of the reverse feeding trucks 8b and 9b are hoppers 10 and 1 for loading components.
It is set as 1.

The central wall 1a of the central trough 3 and the side walls 4a, 5a of the side troughs 4, 5 are provided with rounded end portions as guide portions 1b, 4b, 5b for moving parts between the tracks. I made it smooth.

The central trough 3 and the side troughs 4 and 5 are a pair of leaf springs 13a and 13b, 14a and 14b, 1 respectively.
5a and 15b are independently supported parallel to this on the base 12 and the leaf springs 13a, 13b of the central trough 3 are directed downwards in the direction of the discharge chute 2 and the leaf springs 14a of the side troughs 4, 5. , 14b, 15a and 15b are attached so as to be inclined downwards in the direction opposite to the discharge chute.

On the lower surface of the trough, a mover 16 made of a magnetic metal plate such as iron fixed to the side troughs 4 and 5 across the central trough 1 and a mover 17 fixed only to the central trough 1. Are hung down to face the outer ends of the cores 18a and 18b of the electromagnets 18 and 19 provided on the base 12, and these electromagnets and the mover constitute a drive mechanism.

Reference numerals 18b and 19b in the figure denote coils wound around the cores 18a and 18b of the electromagnet, respectively.

The device of the present invention constructed as described above operates as follows. When an alternating current is supplied to the electromagnets 18 and 19 from a power supply device (not shown), the cores 18a of the electromagnets,
19a intermittently attracts the movers 16 and 17 to give vibration to the trough 1, and the central trough 1 vibrates in the direction of arrow P in the figure, and the side troughs 4 and 5 both vibrate in the direction of arrow Q in the figure. .

At this time, since the weight of the central trough 1 is made equal to the sum of the weights of the two side troughs 4 and 5, the vibration in the horizontal direction is canceled by the entire apparatus, and the vibration damping effect is obtained.

When the parts are put into the hopper parts 10 and 11, the parts are fed back from the hopper part 8 by the vibration in the Q direction.
b and 9b are moved in the direction of arrow A against the climbing gradient, and the parts that have moved the reverse feed tracks 8b and 9b are guided by the guide portions 4b and 5b of the side troughs 4 and 5 to be guided by the central trough 1.
Are moved to the progressive tracks 6b and 7b.

The parts transferred onto the progressive trucks 6b, 7b are moved in the direction of arrow B in the figure by the vibration of the central trough 1 and guided by the guide portions 1b, 1b of the central trough to be guided by the side troughs. It is moved to the reverse feed tracks 8a and 9a.

Similarly, the parts transferred from the reverse feed tracks 8a and 9a to the forward feed tracks 6a and 7a of the central trough are again carried in the direction of arrow B and sent to the alignment section 3.

Excessive parts sent in two rows on the progressive trucks 6a and 7a are dropped by the escape plate 3a onto the progressive trucks 6b and 7b in the lower stage, and one row along the central wall. Only the components lined up in the above are sent to the alignment plate 3b so that their positions and directions can be aligned.

The parts arranged in a line through the escape plate 3a and the alignment plate 3b are arranged in the grooves 2a and 2b of the discharge chute 2.

The supply amount of the component, that is, the moving speed of the component on the track is adjusted by controlling the voltage supplied to the electromagnets 18 and 19 to change the amplitude of the trough.

[0025]

Since the component aligning device of the present invention has the above-mentioned structure, two types of components can be aligned and supplied by one device.

Further, since two kinds of parts are supplied from one discharge chute, the movement width of the part receiving arm of the part assembling machine in the next step can be made as small as possible and the work efficiency can be improved. You can
