Description

DETAILED DESCRIPTION OF THE INVENTION The present invention disentangles a coiled spring by placing it inside a cylindrical drum and using air pressure.
This invention relates to a separating and rectifying machine for aligning and transporting to the next process.

This type of device is required to be small, lightweight, simple in structure, and capable of high-speed and reliable separation and rectification.

FIG. 1 is a system diagram of a separation and rectification device showing a conventional embodiment. In the figure, the springs 10 are separated and rectified in the parts feeder 11, and the springs 10 sequentially fall in the direction of the arrow 12 and enter the conveyance pipe 13. The spring 10 is pushed up in the direction of arrow 15 by the air blown from the air blowing nozzle 14, and the spring 10 is pushed up from the upper opening 16 to the cylinder 1.
Falling to 7. The cylinder 17 has contact plates 18 alternately inside and is operated by a drive mechanism (not shown) to move up and down in the direction of arrow 19, causing the spring 10 falling from the upper opening 16 of the conveying pipe 13 to collide with the contact plates 18. Loosen the intertwined springs 10,
Lead to parts feeder 20. parts feeder 20
Now, the spring 10 is rectified and advanced in the direction of the outlet 21. At this time, the springs 10 that do not come off the entanglement fall on the way to the outlet 21 and are returned to the parts feeder 11 through the pipe 23, and the springs 10 passing through the outlet 21 are blown away in the conveying pipe (not shown) by the air blown from the air nozzle 22. and transported to the next process.

Such a separation and rectification device not only becomes large in size but also has a complicated structure, requiring large equipment costs.On the other hand, the drawbacks of such a separation and rectification device include low separation and rectification ability and high noise generated from the parts feeder and air nozzle. It was hot.

An object of the present invention is to eliminate the above-mentioned drawbacks, and to provide a separating and rectifying machine that is small, lightweight, has a simple structure, and is capable of disentangling, rectifying, and conveying the fluid to the next process at high speed and reliably.

According to the present invention, the above-mentioned object is achieved by forming a cylindrical drum into an upright type, and having a notch portion provided on the inner circumferential side with a notch surface tangentially connected to the inner circumferential surface, and a substantially annular shaped drum formed in the inner circumferential surface. A plurality of through-holes are provided with a V-groove and are drilled from the outer circumferential side, vertically traverse the notch surface and communicate with the V-groove in a tangential direction, and air can flow toward the notch along the inner circumferential surface. a cylindrical drum having an air discharge hole; an intermediate member inserted into the hole of the drum and having a notch at its tip; and one end of the intermediate member and the other end connected to a flexible tube and the intermediate member side. The cylindrical drum includes a connecting tube having at least two air discharge holes diagonally opposite to the flexible tube side, a lid that covers the upper opening of the cylindrical drum, and a fixed base that closes the bottom of the cylindrical drum. This is achieved by configuring so that air can be discharged alternately at predetermined intervals from a plurality of air discharge holes provided in the connecting pipe and the air discharge holes diagonally facing the intermediate member side of the connecting pipe.

Embodiments of the present invention will be described below based on the drawings. Embodiments of the present invention are shown in FIGS. 2 and 3. FIG. 2 is a perspective view of a spring separation rectifier, FIG. 3 a is a plan view of FIG. 2, and FIG. 3 b is a front view of FIG. 2. It is. In the figure, numeral 30 is a cylindrical drum in which an upper cylinder 31 and a lower cylinder 32 are integrally combined in a vertical shape. On the inner circumferential side of this cylindrical drum 30,
It includes a notch portion 34 having a notch surface 33 tangentially connected to the inner circumferential surface, and a substantially annular V-groove 35 bored in the inner circumferential surface. In addition, a cutout surface 33 is bored from the outer circumferential side of the cylindrical drum toward the inner circumferential surface.
A hole 35a that longitudinally traverses the V groove 35 and communicates with the V groove 35 in a tangential direction.
and a notch 3 along the inner peripheral surface of the cylindrical drum 30.
There is a plurality of air discharge holes 37 through which air can flow toward the air outlet 4. The intermediate member 36 has an inner diameter 36a slightly larger than the outer diameter of the coiled spring 38 to be separated and rectified, and has a through hole 3 of the cylindrical drum 30.
A notch portion 36b is provided at a portion inserted into the cylindrical drum 5a and protruding toward the inner surface of the cylindrical drum 30 at the tip. 39 is a connecting pipe whose inner diameter 39a is the same as the inner diameter 36a of the intermediate member 36, and one end thereof is connected to the intermediate member 36.
An air discharge hole 4 connected to the intermediate member 36 and oriented obliquely to the intermediate member 36 side.
0, and a flexible tube 4 whose other end has an inner diameter 41a that is approximately the same diameter as the inner diameter 36a of the intermediate member 36.
1 and is provided with an air discharge hole 42 that is diagonally oriented toward the flexible tube 41 side. This cylindrical drum 30 is attached to a fixed base 43,
At the top, there is an acrylic plate 47 supported by a shaft 45 of a support member 44 attached to the outer circumferential side of the upper cylinder 31 of the cylindrical drum 30 and equipped with a handle 46 that can be opened and closed.
A lid 48 is provided which is lined with.

Next, the separation and rectification of the coiled spring according to the present invention will be explained. After putting a relatively large amount of spring 38 into the cylindrical drum 30 and covering it with a lid 48, air is alternately supplied from the plurality of air discharge holes 37 and the air discharge hole 40 diagonally toward the intermediate member 36 side of the connecting pipe 39. At the same time, air is discharged from the air discharge hole 42 on the flexible tube side of the connecting pipe 39. The group of springs 38 in the cylindrical drum 30 collide with each other due to the air blown out from the air discharge holes 37 and 40 along the inner circumferential surface of the cylindrical drum 30, and the springs 38 in the cylindrical drum 30 collide with each other. Rotating in the direction of arrow 50, the cylindrical drum 30
The group of springs 38 near the inner circumferential surface of the spring 38 collides with the notch 34 again and becomes untangled.
Then, they enter the V groove 35 one after another and line up, and the V groove 35 is 5
It advances in the direction of arrow 0 and passes through the hole in the intermediate member 36 and moves to the connecting pipe 39. Since air is always blown out toward the flexible tube from the air discharge hole 42 of the connection 39, which is inclined toward the flexible tube 41 side, the spring 38 that has reached this point is blown off and transported to the next process. Become so.

Furthermore, in order to further improve the separation and rectification efficiency, this can be achieved by making the single V-groove 35 on the inner surface of the cylindrical drum 30 into a multi-row or spiral groove, or by adding protrusions 51 on the inner surface of the cylindrical drum 30.

The present invention provides a spring separating rectifier which has a simple structure such that the cylindrical drum is slightly modified as described above, is small and light enough to be carried, and is capable of separating and rectifying the flow reliably at high speed. I can do it.
