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

When the electric current is fully input to the control circuit (not shown), AC is applied to each coil 6υ (4 υ 1551) of the electromagnetic vibration feeder (2), parts feeder (3), and Hilinear feeder (4), and the trough of the feeder (2) is turned on. , ball (3'01) The trough t5G of the linear feeder (4) vibrates.Different types of parts are stored in each hopper (7) to (10), and the parts currently stored in the hopper (7) The parts shall be supplied. Only the rotary actuator trowel attached to the hopper (7) is driven, and its rotation axis (
6η is rotated 180 degrees counterclockwise in Fig. 4B to open the gate plate (as shown in Fig. 4A).The other hoppers (8) to the gate plates attached to IJ0 remain closed. It is.

Along with the drive of the rotary actuator iron, the vibrator (c) is also driven, and the hopper (7) vibrates because it is supported by the frame (5) by the spring συ. Due to this vibration, the parts are smoothly cut out from the opening (7a) of the hopper (7) and fall through the part guide a< to the guide chute part (2) of the chute (22). The part c!61'r falls into the trough field of the electromagnetic vibrating feeder (2).The parts are transferred by the vibrating trough and are discharged to the central part of the parts feeder (3' balls 61'r).

The parts are transported along the track (49) within the ball (3η), and when they reach the parts sorting means (4 barrel), the parts that are not in the desired orientation are removed to the pocket (49), and only the parts that are in the desired orientation are removed. From the discharge end of truck t4F9 to the linear feeder (4
) will be transferred to the Trough Group. Inside this trough 151, the parts are transferred while being maintained in a desired posture, and are supplied to the next process (not shown) from the discharge end of the trough (5G).

Note that the component stopper device (6ω) is in the open state.As described above, components are sequentially fed from the trough 61 of the linear feeder (4) in the desired posture, but the components do not over-puff in the trough 151. When state a- (parts are continuous without gaps) is detected by the overflow detector (5 flaws), the drive of the parts feeder (3) is stopped. The light receiving means (59b) receives the light beam from the light projecting means (59a) for a predetermined period of time or more. Part 2 Ida (3) is then driven again.

When the desired number of parts are supplied from the trough (51), the parts stopper device 6G is closed and the parts feeder (3)
In this case, the air cylinder (7f) of the parts removal device η
9 is driven, the drive rod (78) extends and the roller presses the gate plate 61. As shown by the dashed line in FIGS. 6 and 7, the gate plate 3D is placed in the open position and the opening (
) will be released. Along with the drive of the air cylinder (7119), the rotary actuator trowel attached to the hopper (7) is also driven, and the rotation axis is rotated 1 clockwise in Fig. 4A.
The gate plate (68rj) is rotated by 80 degrees and takes the closed position as shown in Fig. 4B.The pie break αQ also stops driving at the same time.

Now, the parts are not discharged from the electromagnetic vibration feeder (2), but are quickly discharged to the outside from the parts feeder (3) through the opening. Note that an ejected parts receiver is placed below the ejected sheet (goods) even though it is not shown in the figure. The parts stopper device 11301 disposed at the tip of the linear feeder (4) is also opened soon, and the parts are also discharged from here.

Ball 6η internal metracks (4 are ball c as is known)
Since the force is inclined downward in the outward direction of the force, the parts are biased toward the side wall and move on the track U, and all the parts that have moved in the direction of the arrow in Figure 6 pass through the opening (c). It is discharged to the outside. Before the gate plate υ opens, all the parts downstream of this K are discharged from the linear feeder (4). It should be noted that a discharged parts receiver is also provided below the discharge port of the linear feeder (4), as shown in the figure, to receive the discharged parts. Together with the discharged parts receiver disposed below the discharge chute of the parts removal device a (4η), these are automatically arranged, and all the parts in the ball (3η and the linear feeder (4) are discharged). The parts may also be automatically returned to the hopper (7) after or upon discharge.

When the parts empty detector installed in the upstream part of the truck (451) detects that the parts in the ball θη are empty, this detection signal causes the parts removal device (4η
The gate plate g3υ at is closed. Note that all the parts that were on the downstream side of the gate plate have already been discharged from the linear feeder (4). It is assumed that the parts transfer speed of the parts feeder (3) and the linear feeder, the distance from the parts removal device (4) to the discharge end of the linear feeder (4), etc. are selected to satisfy these conditions.

When the gate plate of the parts removal device lη closes, only the rotary actuator (661) attached to the hopper storing the next part, for example, hopper (8), is driven.
The gate plate (decoy) rotates counterclockwise and assumes the open position as shown in Fig. 4A. At the same time, the vibrator αη also starts driving. The parts pass through the chute Q″IJ? and enter the electromagnetic vibration feeder (2). Thereafter, the same actions as in the above case are performed.

As described above, various parts can be supplied in desired numbers and in desired postures using the same device according to the requirements of the next process. The required number can be determined by counting the number of parts supplied at the entrance of the next process. Further, if the order of parts to be supplied is determined, program control can be performed. That is, it is possible to automatically drive the rotary actuator attached to the next hopper.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the number of hoppers is four,
Although four types of parts can be supplied, a larger number of hoppers may be provided to supply even more types of parts.

Further, in the above embodiments, the electromagnetic vibration feeder (2) has been fully explained as a common component transfer means, but the present invention is not limited to this, and other transfer means such as a belt conveyor may be used.

In the above embodiment, after the parts feeder (3),
I connected the linear feeder (4), but I omitted it.
The parts may be directly supplied to the next process from the parts feeder (3).

In addition, in the above embodiment, a component stopper device 1 (I3 (lI') is provided at the tip of the linear feeder (4), and is opened when supplying components to the next process, and closed when changing the type of supplied components. However, instead of this supply method,
Parts supply speed required by the next process (number of supplies/unit time)
Depending on the situation, a stopper (one for six companies may be closed).

That is, tact operation may be performed.

As described above, the vibrating component supply device of the present invention is particularly suitable for supplying all kinds of components in small quantities with similar shapes or properties, and the installation area of the device can be minimized. Further, even if the types of parts are different, the supply position (the tip s of the linear near tweeter (4) in the embodiment) can be kept constant. Therefore, the joining operation for different types of parts to the next process can be simplified and can be fully automated.
