Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device for feeding parts into which parts are drawn and pushed into a hoop-shaped or short base material.

Conventionally, when parts manufactured from hoop-shaped or short base materials, such as watch base plates and supports, are supplied to an assembly device, punching is performed during the manufacturing process of the parts,
The parts were aligned using a component alignment device and supplied to the assembly device. However, in the above-mentioned parts aligning apparatus, for example, a vibrating ball feeder, since the parts are in the form of blanks, the number of sorting directions is large and the number of parts supplied is insufficient. In addition, in order to solve this problem, the vibrating ball feeder must be made larger or have a plurality of outlets, which requires a large amount of space. Another method is to shear the parts using a punching press and supply them to the assembly equipment, but for example, for a base plate for a wristwatch, it is necessary to punch out about 10 tons, and the press equipment requires a large amount of space. There were some drawbacks.

The present invention aims to solve the above-mentioned drawbacks, and aims to provide a small, highly efficient, and unprecedented feeding device.
Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of this embodiment,
1 is a short base material into which the part 300 has been extracted and pushed; 2
3 is a feeding device that feeds the short base material 1 at a constant pitch in the direction of the arrow 1000, and 3 is a punching device that pulls out the parts 300 sent by the feeding device 2 from the short base material 1, and the parts 300 are pulled out in the upward direction of the drawing. . Reference numeral 4 denotes a component holding portion for not changing the posture of the component 300 when the component 300 is extracted by the extraction device 3, or for preventing the component 300 from flying out from the extraction device 3.

Reference numeral 21 denotes a lever, and one side thereof has a cam follower that engages with a cam follower receiver 22 provided on the feed rod 23. Reference numeral 25 denotes a block provided on the feeding rod, the tip of which engages with the side surface of the cam 100. It is swung by a sliding pin 24. 26 is a feed claw provided on the feed rod. 32 is a punch provided on the punch shaft 34, 31 is a die provided opposite to the punch, 33 is a lever that gives a stroke to the punch shaft, and 41 is a lever, one side of which engages with the lower surface of the cam 100. and lever 4 on the other side
It is connected to 2. Reference numeral 42 denotes a lever shaft that can drive the component holding section 4 in synchronization with the punching operation. The cam 100 has cam surfaces on both sides that function as arm cams and a plurality of grooves, which are groove cams, provided on the cylindrical surface. Further, 5 is a pick and press, and the parts discharged from the punching device 3 are held by a chuck 52 and conveyed to an assembling device (not shown). To operate this, motor 200
There is a cam 100 on the cam shaft that is driven by the drive of the lever 21 which moves the feed rod 23 in the direction of the arrow 1000 via the cam follower receiver 22 that receives the cam follower, and a lever 21 that moves the feed rod 23 in the direction of the arrow 2000 via the block 25. Activate the sliding pin 24 to be moved. By this operation, the short substrate 1 is conveyed by a predetermined pitch amount from the feeding rod 23 via the feeding claws 26. The conveyed short base material 1 is synchronized with the above operation by the cam 100 fed into the punching device 3, and the punch 32 corresponding to the die 31 is actuated via the lever 33 and punch shaft 34, thereby cutting the part 300 into the short base material. At this time, the holding part 4 is operated by the cam 100 via the lever 41 and the shaft 42 in synchronization with the above operation to prevent the part 300 from flying out. Thereafter, the component 300 is held by a chuck 52 provided on the pick and press 5, and is conveyed to an assembling device (not shown) by the telescopic and rotational movements of the pick and press.

According to the present invention, the pulling force of the short base material 1 and the component 300 is, for example, about 20 kg for a wristwatch base plate,
The output of the motor 200 is approximately 25 W, which is sufficient, and the supply device is small and extremely efficient.

In the embodiments of the present invention, the punched and pressed material was explained using a short base material, but it goes without saying that the same effect can be obtained for a hoop base material.
