Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a small parts supply device that intermittently supplies small parts such as pierce nuts to a driving device.

(Prior art) As a device for feeding small parts such as pierce nuts to a small parts driving device that operates intermittently, a flexible parts supply pipe is connected to a parts outlet of a parts feeder. However, since the parts feeder only has the function of continuously feeding small parts, it is possible to accurately synchronize with the intermittent operation of the driving device and prevent parts from being fed. Furthermore, if there is a large distance between the parts feeder and the driving device, there is a problem that it is difficult to feed small parts smoothly due to internal friction of the parts supply pipe.

(Means for Solving the Problems) The present invention is a small parts supply device that has been developed to solve the conventional problems as described above, and is a supply pipe base connected to a small parts driving device. A chute for feeding small parts toward the supply pipe continues at the end thereof, and an air vent is provided on the lower surface near the lower end of the chute, and a base end of the supply pipe is provided with a chute for feeding small parts into the supply pipe through the air vent. A compressed air conduit is installed to intermittently inject compressed air in synchronization with the operation of the driving device, and an air vent is provided in the lower part of the chute to prevent small parts from moving backward. It is something to do.

(Example) Next, the illustrated embodiment will be described in detail.

In the figure, reference numeral 1 denotes a driving device for small parts such as pierce nuts, which is equipped with a press head that moves up and down intermittently. A chute 6 into which small parts are sent continues, and an air vent 8 is provided in the lower surface near the lower end of the chute 6. Further, a compressed air conduit 3 is connected to the base end of the supply pipe 2 for intermittently injecting compressed air into the supply pipe 2 through the air vent 8 in synchronization with the operation of the driving device 1. It is attached via 4. The compressed air conduit 3 is provided with a solenoid valve 5 for controlling the compressed air connected thereto. Additionally, an air vent 9 is provided in the lower part of the chute 6 to prevent small parts from moving backwards.
will be provided. Note that 7 is a parts feeder connected to the upper end of the chute 6.

In this structure, a parts feeder is installed in a chute 6 which is connected to the base end of a supply pipe 2 connected to a small parts driving device 1 and feeds small parts toward the supply pipe 2. The small parts 20 from 7 are dropped by their own weight to fill the supply pipe 2 continuously, and compressed air from the compressed air conduit 3 attached to the base end of the supply pipe 2 is supplied to the supply pipe 2. If the air is injected into the supply pipe 2 through the air vent 8 provided on the lower surface near the lower end of the chute 6 intermittently in synchronization with the operation of the driving device 1, small parts that operate intermittently can be driven. The first piece of the small parts 20 is force-fed toward the driving device 1 in exact synchronization with the operation of the driving device 1. As mentioned above, the compressed air injected into the supply pipe 2 through the air vent 8 blows a part of it up into the chute 6 and blows the small parts 20 filled into the third pipe.
As shown in the figure, some of the compressed air is blown back, but some of the compressed air is released to the outside from the air vent 9 provided at the lower part of the chute 6 to prevent the small parts 20 from moving backward. Many of the small parts 20 are not reversed. And the driving device 1
When the injection of compressed air is stopped in synchronization with the operation of is precisely supplied to the driving device 1 one by one.

(Effects of the Invention) As is clear from the description of the above embodiments, the present invention has the advantage that each of the small parts that are continuously filled from the chute into the supply pipe connected to the small parts driving device is inserted into the supply pipe. Compressed air is injected intermittently from a compressed air conduit attached to the base end to the driving device in synchronization with the operation of the driving device, and the small objects are It is possible to always accurately feed small parts to the driving device without parts moving backwards, and even if there is a large distance between the parts feeder and the driving device, the compressed air By using this system, small parts can be fed without any trouble, and it has great practical value as it solves the problems of conventional small parts feeding devices.
