Abstract

PURPOSE:In all parts arranger/feeder provided in a shoot to be coupled with a parts feeder, to release biting of parts efficiently by reciprocating a rotary member if the part doesn't pass said rotary member for changing the parts position within predetermined time. CONSTITUTION:The position of parts to be discharged while being arranged onto a shoot 21 from a vibration parts feeder 20 is decided by a parts position decider 23 the output of which is used for controlling a horizontal rotary section 24 and vertical rotary section 26 to arrange the parts position in predetermined state. Here the parts passed through each rotary section 24, 26 are detected the passing by parts pass detectors 25, 27 then carried to next process. If said detectors 25, 27 will not detect passage of parts within predetermined time, it is decided to be biting thus to control each rotary section 24, 26 to reciprocate.

DETAILED DESCRIPTION OF THE INVENTION The present invention is provided in a small seat which is connected to a discharge port of a "vibrating parts tweeter" in a downwardly inclined manner, and which aligns all the parts to be transported on the chute in a constant posture and transfers them to the next process. Concerning the feeding of all parts to be supplied.

This type of device has been proposed, for example, by the applicant in 41 Japanese Patent Publication No. 55-4.
In these devices σ disclosed in Japanese Patent Application No. 8527, the rotating body and the strike sensor ζ have the configurations shown in FIGS. 1 and 2. That is, in FIGS. 1 and 2, the chute (1) is connected obliquely to the discharge port of a known vibrating parts feeder (not shown), and the parts m are conveyed along the transfer path (2) of the chute. Due to the action of gravity, it slides and reaches the rotating body (5). FIG. 4 (necessarily, a gate device for supplying the chute upstream 11i111/koiI group product m of this rotary body (5) to - pieces, and a component attitude determination device next to this device is provided in the vicinity of the chute (υ), After passing through these devices, the part m is supplied to the transfer path (<6) VC of the rotating body (5).
If it is detected that the part m is in a position in which the direction should be changed by 1800 in the transfer plane of 6), the stopper (7) is lowered before the part m reaches the transfer path (6) of the rotating body (5). parts m
After temporarily stopping the rotating body (5), the rotating body (5) moves along its transfer path (6).
) in the same plane as the transfer path (2) of the shoe 1 (1), and changes the direction of the part 7n. The stopper (7) then rises and releases this part m downstream of the sheet (1)/).

The stopper (7) is driven by an air cylinder (9), and the air cylinder (9) has a rond (I),
It is fixed at l. The air cylinder (9) is fixed to the guide part attached to the chute (IJ's both n!

The rotating body (5), which has a curved surface, is located in a circular notch (4) formed in the chute (1) and is rotated by 180° by a rotary actuator (2). It is fixed to the drive shaft 04 of 1 through a support member 05i.

The rotary actuator (6) is driven by compressed air and is fixed to the shoe (17) via a spacer member (13aX13b).

Since the conventional parts conveying device has the rotor and the stopper as described above, if the parts are
Before the rotating body (5) completely transfers to the transfer path (6), the rotating body (5) collides with the rotating shaft or the stopper (7) and rebounds, causing the shoe 1- (IJ transfer path (February) 1
The rotating body (5) rotated when it protruded from 111! ll
As shown in Fig. 3, part m is I of the rotating body (5).

The 7-movement of the stopper +2!11 is performed after the first component passage detection device (27) detects that the previous) X13 product has passed the first component.

b When the component 1n of B is supplied to the vertical rotating part (26), it comes into contact with the stopper (29+) and stops immediately.Then, the rotating body (3) moves into the chute (in the plane perpendicular to the transfer path of 211). As a result, part m of bB is turned upside down, and is fed from the position of cB, that is, n [the lower end of the sea-11211 in the desired position].

In addition, when the part m of bB passes the first passage detection device f^ (25), this passage signal is used to separate the next 7715 items m1 into the gate device (6) and separate the parts posture discrimination device ( 231VC is supplied.This part m. m passes through the horizontal rotating part (goods). At this time, the previous part cB has already passed through the vertical rotating part (2

The stopper (29) that can be opened also moves backward to the position shown in the figure, i. supplied from the bottom end (Z).

When the part m is in the 1111th tone on the sheet tray υ, the above-mentioned action takes place, but now, as shown in Figure 3, the part m is in 2llL'c, j, ?However, in this implementation color, the attitude of aA shown in 3+xl is the desired attitude, so in Fig. 3, it is different from the attitude shown. , Suppose that the part m in the posture a, D (7J) is bent in the posture aD in FIG.

1jJ Q+υ, as shown in Fig. 3, part m gets caught between both walls of the chute (211) and both walls of the rotating body (5).This causes horizontal return control. circuit (7 cycles set at 3) [Even after the elapse of a certain period of time, the component passage signal cannot be obtained from the first component passage detection device (25). Therefore, after horizontal T (jυ from the control circuit θa,

The first action takes place.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these.(<Various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, a horizontal rotation part and a vertical rotation part were provided, and one horizontal double-action control circuit and one vertical double-action control circuit were connected to each, but depending on the shape of the parts to which it can be applied, the 10,000 yen may be omitted.

Since the distance from > to the horizontal rotating part f2-+1 t is sufficiently large compared to the distance to the horizontal rotating part (rounding vertical rotating part (26)), the phenomenon of parts getting caught is mostly caused by the horizontal rotating part. Therefore, the vertical double-motion control circuit (33) may be omitted in some cases.

In the above embodiment, there are 8

As described above, according to the parts sorting device n of the present invention, the parts are transferred between the transfer surface of the chute and the transfer surface of the rotating body at the same time.
Even if the sword is inserted, it will automatically and firmly lock after a certain period of time.
The jamming is released and the device can return to normal 'fL+ geometry. Particularly in the past, is there a phenomenon of parts being caught?
