The separating device 22 is in an upward state in which it is rotated by 90 ° R1. In FIG. 5, the separator 20 is shown rotated in the 45 ° R1 direction. In FIG. 6, the separating device 20 has 90
It is in a state of being rotated in the R1 direction. In FIG. 7, the separating device 20 is again in the horizontal state, that is, in the state of being rotated in the 90 ° R2 direction.

The separating device 20 has a transfer means shown in FIGS. 12 and 13. In this transfer means, a shaft unit 50 is provided for the support plate 48. The shaft unit 50 has an upper shaft 52 and a lower shaft 54. The tip 5 of the lower shaft 54 is smaller than the distance L1 between the tip 56 of the upper shaft 52 and the support plate 48.
The distance L2 between 8 and the support plate 48 is set large.

The upper shaft 52 is mounted by a mounting portion 60 so as to be rotatable around the central axis. The upper shaft 52 is tilted so as not to be perpendicular to the support plate 48. The lower shaft 54 is attached to the support plate 48 vertically, that is, so that the axial direction thereof is horizontal, and is supported rotatably around the central axis. Therefore, the upper shaft 52 and the lower shaft 54 are not parallel to each other.

The lower shaft 54 is rotationally driven by a motor 62. When the lower shaft 54 rotates, its rotational force is transmitted via the transmission roller 64 and the transmission belt 66 to the upper shaft 5.
2 is transmitted. Thereby, the tip 5 of the upper shaft 52
6 is rotationally displaced or swung so as to draw a circular shape. The transmission belt 66 has three rollers 70, as shown in FIG.
It is hung on 72 and 74. The support plate 48 has side plates 80 and 82.
Is fixed between. In addition, by means not shown,
The upper shaft 52 is vertically movable in the A1 direction.

Further, the ring-shaped component supply device has the following detection sensors. The first detection sensor 100 of FIG.
The parts stocker 16 of the rubber belt 30 as shown in FIG.
Used to confirm the transfer from the upper shaft 52 to the lower shaft 54. The first detection sensor 100 is a transmissive optical sensor, and as shown in FIG.
00a and photodiode 100b. As a result, the rubber belt 30 blocks the light of the light emitting diode 100a and the photodiode 100b blocks the light emitting diode 100a.
If the light of a is not received, the control device 200 of FIG. 11 determines that the shaft unit 50 has received the rubber belt 30.

The second detection sensor 110 shown in FIG. 7 is also a combination of a light emitting diode and a photodiode. The second detection sensor 110 is provided corresponding to the first separating device 20, and one or a plurality of rubber belts 30 are provided from the shaft unit 50 of the first separating device 20.
It is confirmed whether or not has fallen to the predetermined position P3. Figure 10
Shows the state after one rubber belt 30 has dropped to the predetermined position P3.

A similar third detection sensor (not shown in FIG. 7) is provided for the second separating device 22,
It is confirmed whether or not the one or more rubber belts 30 of the shaft unit 50 of the second separating device 22 have dropped to a predetermined position P3 next to the predetermined position P3. These confirmations are performed by the control device 200 in FIG.

The fourth detection sensor is not shown in FIG.
It is provided near the final stage 150. Figure 10
The rubber belt 30 dropped like the air cylinder 12
It is provided for confirming that the final stage 150 is pressed to the standby position by means such as 3,124. The third and fourth detection sensors are the first and second
It has the same configuration as the detection sensor.

Referring to FIG. The first to fourth detection sensors 100, 110, 120, 130, the motor 62, the motor 18, the air cylinders 40, 42, 123, 124,
It is connected to the control device 200.

Next, the feeding operation of the rubber belt 30 will be described. First, as shown in FIG. 1, a plurality of rubber belts 30 are stored in each parts stocker 16. Motor 18
Is operated to drive the chain 14 to position one parts stocker 16 at the position P1 corresponding to the separating device 20. At the same time, the other parts stocker 16 also has a separating device 2
Position P2 corresponding to 2. At this time, the air cylinder 40 (see FIG. 4) of the separating device 20 is connected to the rod 4
0a is extended and the shaft unit 50 is horizontal as shown in FIG. On the other hand, the rod of the air cylinder 40 of the separating device 22 is contracted, the shaft unit 50 is vertical, and the shaft unit 5 is already in the vertical position.
The rubber belt 30 is fitted in the position 0.

The rod 40a of the air cylinder 40 contracts, and the separating device 20 rotates 90 ° in the R1 direction about the pin 34 as shown in FIG. At this time, the tips of the upper shaft 52 and the lower shaft 54 pass through the holes 28 of the parts stocker 16 and enter the bundle of rubber belts 30 in the parts stocker 16. When the separating device 20 has completely rotated 90 °, the rubber belt 30 transfers from the parts stocker 16 to the shaft unit 50, and as shown in FIG.
4 points up. Therefore, the rubber belt 30 is separated by the separating device 2.
It's on top of 0. When the transferred rubber belt 30 is detected and confirmed by the first detection sensor 100 shown in FIG.
As shown in FIG. 5, the rod 40a of the air cylinder 40 extends and the separating device 20 rotates 90 ° in the R1 direction. In this state, the bundle of rubber belts 30 is located at the base of the upper shaft 52 and the lower shaft.

Next, the upper shaft 52 rises in the X direction in FIG. As a result, the rubber belt 30 is stretched by the upper shaft 52 and the lower shaft 54 as shown in FIG. When the motor 62 shown in FIG. 1 is driven, the upper shaft 52 rotates with its tip swinging, and the lower shaft 54 rotates normally.
As a result, tension and slack are repeatedly applied to the rubber belt 30 with the rotation of the upper shaft 52 and the rotation of the lower shaft, which have non-parallel inclination angles, so that the rubber belts 30 are conveyed and separated as shown in FIG. go. Moreover, since the distance between the upper shaft 52 and the lower shaft 54 has a taper relationship, when both shafts 52 and 54 continue to rotate, they gradually move to the tips of the upper shaft 52 and the lower shaft 54, and each rubber belt 30 moves during the transfer. They are lined up and transported.

There is a dimensional difference between the tip of the upper shaft 52 and the tip of the lower shaft 54, and since the upper shaft 52 is inclined, the rubber belt 30 that has passed through the upper shaft 52.
Leaves the upper shaft 52 and falls downward from the tip of the lower shaft 54. The feeding device of this embodiment is particularly applicable to the rubber belt 3
0 is installed in an automated production line that automatically attaches 0 to an assembly machine, and its supply operation must be performed at the same timing as other automated robots and devices. Therefore, the supply cannot be interrupted.

Therefore, another device is added near the separating devices 20 and 22. When the inside of the parts stocker 16 becomes empty as shown in FIG. 7, the motor 18 of FIG. 1 is activated to send the next parts stocker 16 to the corresponding positions P1 and P2 of the separating devices 20 and 22. While the rubber belt 30 is moving from the parts stocker 16 to the one separating device 20, the shaft unit 50 of the other separating device 22 is performing the above-described separating / conveying operation of the rubber belt 30, and the supply of the rubber belt 30 is performed by the separating device 20, There is no interruption by the alternating action of 22.

On the other hand, the upper shaft 5 which is also called a transport shaft
2 and the lower shaft 54 are rotating, the rubber belt 30
Will sequentially fall to a predetermined position P3 in FIG. 10 regardless of the predetermined timing and the number of other robots used. Predetermined position P3
When the rubber belt 30 falls, the second detection sensor 110 shown in FIG. 7 detects the rubber belt 30. This detection signal causes the air cylinders 123 and 124 in FIG. 10 to expand, and the pushing member 89 moves the rubber belt 30 to the final stage 150, and the next rubber belt 30 moves to a predetermined position until the rubber belt 30 moves to the final stage 150. The rotation of the upper shaft 52 and the lower shaft 54 is stopped so as not to drop to P3. When the rubber belt 30 is placed on the final stage 150, the fourth detection sensor 130 of FIG. 11 detects the rubber belt 30 and the rubber belt 30 is sent from the final stage 150 to the assembly machine of the next stage by means not shown. When the rubber belts 30 of the upper shaft 52 and the lower shaft 54 shown in FIG. 9 have all been supplied, the separating device 20 determines that the rubber belt 30 is gone by the signal of the detection means (not shown) of the rubber belt, and the separating device 20 moves in the R1 direction of FIG. Rotate to. As a result, the rubber belt 30 is transferred from the parts stocker 16 to the shaft unit 50 again.

In any case, while the rubber belt 30 is moving in one separating device 20, the separating operation of the rubber belt 30 is performed by the other separating device 22. The reverse is also true. That is, one performs the separating operation of the rubber belt 30, and the other is in the standby posture state.

By repeating the above operation, a large number of rubber belts can be moved one by one individually to a predetermined assembly machine at a predetermined timing. It should be noted that the chain 14 of FIG. 1 is of a vertical circulation type because of the consideration of the space factor (space saving). In addition to this, it is also possible to configure a horizontal movement or a rotary table type.

14 and 15 show another embodiment of the shaft unit of the separating device. The upper shaft 152 of the separating device 120 is inclined and the lower shaft 154 is eccentrically rotatable.

In yet another embodiment of the shaft unit of FIGS. 16 and 17, the upper shaft 252 is horizontal and the lower shaft 254 has two fin-like protrusions 280, 282. Alternatively, the same purpose can be achieved by performing a process such as cutting off a part of the periphery of the lower shaft instead of the protrusion, and rotating the lower shaft in a state where the lower shaft is not a perfect circle. Further, the number of shafts is not limited to two and may be three or more. Also in the ring-shaped component supply device shown in these embodiments, the same operation as in the first embodiment can be exhibited.

[0040]

As described above, according to the present invention,
The ring-shaped parts can be gradually separated, conveyed, and aligned by rotating the shaft, which prevents the quality deterioration of the elastic ring-shaped parts such as rubber belts, fulfills the supply function, and enables continuous large-volume supply. .. Moreover, since the gravity is not used for the separation and the alignment, but the shaft is actively used, the reliability is high. For these reasons, it is suitable for incorporation in an automated line.
