[0002]

2. Description of the Related Art As a component transfer device of this type, a device as shown in FIG. 9 is known.

That is, in the figure, reference numeral 1 denotes a carrying jig, and the carrying jig 1 has a detection plate 3 attached to one side thereof and a component 2 placed on the upper surface thereof.

The carrying jig 1 is placed on a carrying conveyor 4 as shown in FIG. 10 and carried. First and second detection sensors 5 and 6 are arranged on one side of the conveyor 4 at predetermined intervals along the traveling direction. In addition, first and second stop cylinders 7 and 8 are arranged at a substantially central portion of the transport conveyor 4 at predetermined intervals along the traveling direction thereof.

Then, as shown in FIG. 11A, when the transport conveyor 4 travels, the transport jig 1 is transported. At this time, the stopper 8a of the second stop cylinder 8 is raised, and the carrying jig 1 comes into contact with the stopper 8a of the second stop cylinder 8 to stop as shown in FIG. 11 (b). The detection plate 3 of the transport jig 1 is detected by the first detection sensor 5. As a result of this detection, as shown in the operation flow of FIG. 12, the stopper 7a of the first stop cylinder 7 rises and the subsequent conveyance jig 1 comes into contact and is stopped. After this, work on the component 2 is started. When the work on this component 2 is completed,
As shown in FIG. 11C, the stopper 8a of the second stop cylinder 8 is lowered to carry the carrying jig 1, and FIG.

[0006] Thereafter, in the same manner, the subsequent conveying jig 1
Are transported and work is performed.

[0007]

However, in the prior art, the first and second stop cylinders 7 and 8 are required, and the operation of the first and second stop cylinders 7 and 8 is the same as that of the first stop cylinder. And the second detection sensors 5, 6
Since it is controlled by the detection signal of, the number of parts becomes large,
There was the problem of increased costs.

Further, since the first and second stop cylinders 7 and 8 are located at substantially the center of the conveyor 4,
The stopper 8a of the second stop cylinder 8 cannot be raised until the transport jig 1 completely passes through the second stop cylinder 8. Therefore, the stopper 7a of the first stop cylinder 7 cannot be lowered until the transport jig 1 completely passes through the second stop cylinder 8, and during that time,
The subsequent transfer jig 1 is in a stopped state. Therefore, the transfer jigs 1 ... Can not be continuously transferred to the work position, resulting in poor processing efficiency.

Therefore, an object of the present invention is to provide a parts conveying device capable of efficiently feeding a conveying jig to a predetermined position with a small number of parts.

Therefore, the carrying jig 11 is the carrying conveyor 1
4 is conveyed, as shown in FIG. 5 (a), at this time, the stopper 16a of the stop cylinder 16 is raised, and the conveyance jig 10 is projected as shown in FIG. 5 (b). The portion 12 is a stopper 16a of the stop cylinder 16 described above.
Is stopped by abutting against. At this stop,
As shown in the operation flow of FIG. 6, the detection sensor 17 detects the detection plate 13 of the transport jig 11 to confirm the arrival, and the assembly and processing work of the component 20 is started.

Further, the transfer jig 11 in operation is brought into contact with the subsequent transfer jig 11 which has moved from the previous step, and is stopped as shown in FIG. 5 (c).

After the work is completed, the control means 25 lowers the stopper 16a of the stopping cylinder 16 so that the carrying jig 1
1 starts moving. When the detection sensor 17 confirms the passage of the detection plate 13 of the conveyance jig 11, the control means 2
5 raises the stopper 16a of the stop cylinder 16 as shown in FIG. 5 (d). As shown in FIG. 5 (e), the stopper 16a of the stop cylinder 16 is brought into contact with the protrusion 12 of the succeeding conveyance jig 11 to stop.

Thereafter, the same operation is sequentially continued, and the conveyance jig 20 continues to be conveyed and stopped.

As described above, the stop cylinder 16 is positioned outside the transport path 14a and the transport jig 11 is used.
The projecting portion 12 is projected to the outside of the transport path 14a, and the projecting portion 12 is brought into contact with the stopper 16a of the stop cylinder 16 to stop the projecting portion 12. Can be brought into contact with and stopped.

Further, by the detection sensor 17, the projecting portion 12 of the carrying jig 11 is stopped by the stopper 16 of the stop cylinder 16.
When the passage of a is detected, the stop cylinder 16
The stopper 16a is raised to bring the subsequent projecting portion 12 of the carrying jig 11 into contact therewith and stop it.

Therefore, the number of the stop cylinder 16 and the detection sensor 17 is only one each, and the plurality of transport jigs 1
The movement and stop of 0 can be controlled, the number of parts can be reduced, and the subsequent transport jig 10 can be sent to the work position at the same time as the delivery of the preceding transport jig 10 is performed, and the waiting time is short, and the processing can be performed. The efficiency can be improved.

The stop cylinder 16 can be moved to any position and fixed in the mounting groove 19 by loosening the screws 18 and 18.

Further, in the above-described embodiment, the projecting portion 12 of the carrying jig 10 is formed to project substantially at the center of both sides of the jig plate 11, but the present invention is not limited to this, and as shown in FIG. ,
The protrusions 21 may be formed on both ends of the carrying jig 10 on the tip side.

Further, as shown in FIG. 8, the protrusions 31 may be formed at the rear ends of both sides of the carrying jig 10.

[0032]

As described above, according to the present invention,
A projecting portion that projects outward from the transport path is provided on the transport jig, and the transport jig is stopped by bringing the projecting portion into contact with the stopper of the stop means, so that the transport jig subsequent to the stopped transport jig is stopped. The tool is brought into contact and stopped, and after the transportation jig is stopped by the stopping means for a predetermined time, the control means releases the contact between the protruding portion of the transportation jig and the stopper to carry out the transportation treatment. At the same time that the tool is transported and the projecting portion passes through the stopper, the stopper is returned and the projecting portion of the subsequent transport jig is brought into contact and stopped. Move the tool into place,
You can stop. Therefore, the number of parts can be reduced, and the cost can be reduced.

Further, the preceding carrying jig can be sent out from the predetermined position and at the same time, the following carrying jig can be sent into the predetermined position, so that the waiting time can be eliminated and the processing efficiency can be improved.

Furthermore, by projecting the projecting portion of the carrying jig to the outside of the carrying path, the stop means can be installed at the outer part of the carrying path, and the position can be easily changed when the working process is changed. Can be changed.
