Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device for ring-shaped conveyed members.

Conventionally, the work of sorting several types of ring-shaped conveyed members having different outer diameters, which are conveyed along a conveyance path, into the same type has been done exclusively by hand by an operator. This made the work complicated, time-consuming, and inefficient.

It is an object of the present invention to eliminate the drawbacks of the above-mentioned conventional methods, and to make it possible to efficiently sort several types of ring-shaped conveyed members as described above in a short time and without requiring human labor. .

The object of the present invention is to provide a receiving member which randomly receives several kinds of ring-shaped conveyed members having different outer diameters on a machine frame so as to be able to vibrate freely by a vibration mechanism, and to attach a plurality of flat plates to the receiving member in the conveying direction. At least two types of through holes with different diameters are provided in this flat plate, which are inclined downward and are arranged in series with a step formed between adjacent ends in the conveying direction, and through holes of different diameters are made to allow the conveyed member to fall in order from the smallest outer diameter. To provide a sorting device for a ring-shaped conveyed member, in which a large number of holes are drilled in a staggered manner in the vertical and horizontal directions, starting from the hole with the smallest diameter, and the holes with the smallest diameter are arranged over the two flat plates forming the step. achieved by.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1A shows three types of ring-shaped conveying members A, B, and C, each having a different outer diameter. These conveyed members A, B, and C are formed by punching an integrally molded product using a die and punch of a forging machine, as shown in Fig. 1B, and then sent to a sorting device described later by a conveyor. It is something.
In this embodiment, the conveyed members A and C are the inner and outer races of a bearing, and the conveyed member B is a flange that connects the members A and C, and is discarded after being separated.

A sorting device 1 is shown in FIGS. 2 and 3, and a machine frame 2 of this sorting device 1 includes conveyed materials A, B,
A receiving member 3 that randomly accepts C is suspended via a plurality of tension springs 4 and is supported so as to be able to vibrate. The receiving member 3 is composed of both side plates 5, 5 and a connecting plate 6 that connects one end edge of the both side plates 5, 5. Vibrators 7, 7, such as vibration motors, which vibrate the receiving member 3 are fixed to the outer walls at one ends of the side plates 5, 5. On the inner wall of the receiving member 3, there are a plurality of flat plates 10, 11, 12 for transporting the transported members A, B, C by the vibrations of the vibrators 7, 7.
are inclined slightly downward in the conveying direction, and the adjacent ends in the conveying direction are stacked vertically at a predetermined interval, and are fixed in series in a stepwise manner so as to form a step. The flat plates 10 and 11 have through-holes 14 vertically and horizontally formed in a staggered manner to allow the transported member C to fall therein, and the flat plate 12 has through-holes 15 vertically and horizontally formed in such a diameter that the transported member B can fall therethrough. The holes are drilled in a staggered pattern. 17, 18, 19 are collection boxes,
The flat plate is separated by through holes 14 and 15 having different diameters, and the falling conveyed members A, B, and C are collected in the same type. A conveyor 20 conveys the conveyed members and supplies them to the receiving member 3 at random.

Next, the operation of the above embodiment will be explained.

First, the vibrators 7, 7 are activated to vibrate the receiving member 3 and the flat plates 10, 11, 12 provided thereon. In such a state, when the conveyed member is sent to the conveyor 20, the conveyed member is
B and C are randomly supplied from the conveyor 20 into the receiving member 3 and accepted.

When the transported members A, B, and C received in the receiving member 3 which is vibrating as described above are supported by the flat plate 10, the transported members C are moved into the through hole 14 by the vibration. and is collected in the collection box 17. However, when the conveyed members are supplied from the conveyor 20, as shown in FIG. 4, for example, the conveyed members C may be superimposed on the conveyed members R. In such a case, it is difficult to eliminate the overlapping state of the transported members B and C by vibration alone, and the transported member C cannot fall through the through hole 14 of the flat plate 10 at all. Therefore, the transported member C placed on top of the transported member B is transported as it is on the flat plate 10, and then transferred to the flat plate 11.
When being transferred to the flat plate 10, the flat plate 10 and the flat plate 11 are inverted due to the step formed between their adjacent ends, and are supported by the flat plate 11 after being released from the overlapping state. Then, it falls through the through hole 14 of this flat plate, and similarly falls into the collection box 17.
will be collected.

As described above, the transported member C is transferred to the flat plates 10 and 1.
1 falls through the through hole 14 while transporting the transported members A and B, and are completely separated from the transported members A and B. Therefore, only the conveyed members A and B are transferred from the flat plate 11 to the flat plate 12;
Since there is no polymerization state as described above between B and B at this point, further division is performed on this flat plate 12. In this case as well, the vibration causes the conveyed member B to fall from the through hole 15 of the flat plate 12 and be collected in the collecting box 18.

The conveyed object (i) that does not fall through the through hole 15 of the flat plate 12 and is conveyed as it is on the flat plate 12 falls directly from the tip of the flat plate 12 into the collection box 19 and is collected.

As described above, among the three types of ring-shaped transported members A, B, and C having different outer diameters, the transported member C is inserted into the through hole 14 of the flat plates 10 and 11, and the transported member B is inserted through the through hole of the flat plate 12. By conveying the conveyed members A as they are through the holes 15, they are sorted into the same type by dropping them in descending order of their outer diameters.

In the above embodiment, three types of conveyed members were mentioned, but the present invention is not limited to these, and any type can be selected. In addition, the arrangement position of the through hole on the flat plate through which the transported member is dropped, the diameter of the through hole, the number of flat plates, etc. are merely examples, and the design may be changed as appropriate without departing from the gist of the present invention. Needless to say, it is possible to do this.

The present invention is as described above, and can efficiently sort several types of ring-shaped conveyed members into the same type in a short time and without requiring human labor, and can significantly improve the sorting work. Moreover, in the above-mentioned division, in particular, steps are formed between adjacent ends of the plurality of flat plates in the conveying direction, and holes with small diameters are drilled in the flat plates across the two flat plates forming the steps. Because they are arranged side by side, even when the conveyed parts are stacked on top of each other, the level difference eliminates this situation and makes it possible to perform the sorting work reliably. has.
