2. Description of the Related Art A conventional work separating apparatus is shown in FIG. Reference numeral 20 denotes a cylindrical portion having an upper portion into which a work input hole 21 is opened, and a lower portion of the cylindrical portion 20 is provided with a work take-out hole 22 having a gap approximately twice the thickness t of the work W. . A rotating disk 23 that is rotated by a motor or the like is disposed below the cylindrical portion 20, and a projection 24 that projects upward is formed on the rotating disk 23. Then, a large number of works W are randomly inserted into the cylindrical portion 20 through the work insertion holes 21. At this time, there is a possibility that the workpieces W may be put in an overlapping state, and when the material to be formed such as an O-ring or a square ring is a workpiece W using an elastic member such as rubber, the overlapping state is severe. And the cylinder part 2
A large number of workpieces W thrown in 0 fall on the rotating disk 23, while the rotating disk 23 rotates in the cylindrical portion 20. According to the above, the work W on the rotating disk 23 is discharged to the outer peripheral side by receiving the centrifugal force of the rotating disk 23. At this time, the work W is released from overlapping by colliding with the projection, and And splatters into the cylindrical portion 20. And the work W which has reached the work take-out hole 23
Is discharged from the work take-out hole 22 as a single work W by forming the gap of the work take-out hole 22 to be approximately twice the thickness t of the work W, and the discharge of the work W is continuously continued thereafter. It is done on a regular basis.

[0003]

According to such a conventional work separating apparatus, there are the following problems. In the cylindrical portion, the overlap of the works W is released, and only the single separated work is discharged from the work take-out hole. Therefore, it is not guaranteed that the work continuously enters the work take-out hole, and the work cannot be continuously separated and supplied. This is a major factor that hinders improvement in production efficiency of automatic assembly of products. Among the single separated workpieces, those that could not enter the work take-out hole collide again with the protruding part of the rotating disk and are scattered, and this continues until they enter the work take-out hole. It is repeated. According to this, the work may be damaged, which is not preferable in quality control.

[0004] The work separating apparatus according to the present invention has been made in view of such disadvantages, and has as its object to provide a work separating apparatus having a high work separating and supplying capability.

[0005]

In order to achieve the above object, the work separating apparatus according to the present invention comprises: a rotating body 1 that rotates in conjunction with a rotation source M;
And a cylindrical portion 8 surrounding the periphery of the rotating body 1.
Is formed by a cylindrical portion 3 having a constant cross-sectional diameter, and a conical cylindrical portion 4 having a shell surface which extends upward from the upper end of the cylindrical portion 3 and whose cross-sectional diameter gradually decreases upward. The shell surface 5 includes a first blade 7 that is formed continuously along the shell surface 5 and protrudes from the shell surface 5 to the cylindrical portion 3. An annular gap S about twice the thickness t of the workpiece W with respect to the outer diameter of the portion 3
An inner cylindrical portion 9 having a cross-sectional diameter forming an inner cylindrical portion 9
And a second blade portion 12 which is erected inward along the longitudinal direction of the rotating body 1 and continuously formed facing the cylindrical portion 3 and the conical cylindrical portion 4 of the rotating body 1 and penetrates the cylindrical portion 8. Drilled,
A work take-out hole 11 opening toward the lower end 3A of the cylindrical portion 3 of the rotating body 1; the rotating body 1 is rotatably arranged in the inner cylindrical portion 9 of the cylindrical portion 8; The work W to be injected is separated one by one by a first blade portion 7 protruding from the shell surface 5 and a second blade portion 12 protruding from the cylindrical portion 3. The workpieces W are supplied one by one into a gap S formed by the inner cylinder 3 and the inner cylindrical portion 9, and the works W held one by one in the gap S are sequentially discharged from the work take-out holes 11.

[0006]

The work is randomly input into the conical cylindrical portion in the cylindrical portion. The work descends on the shell surface of the rotating body. At the upper part of the shell surface, for example, four works overlap each other. When the workpiece reaches the center of the shell surface, two of the four workpieces abut on the second blade and scatter, and only the remaining two workpieces that do not abut on the second blade are in the shell surface. Present in the central part. When the work reaches the lower part of the shell surface, one of the two works comes into contact with the second blade portion and scatters, and only the remaining one work that does not contact the second blade portion is in the shell surface. This one work is present in the lower part and descends sequentially into the gap, and this work is discharged from the work take-out hole of the cylindrical portion.

Reference numeral 8 denotes a cylindrical portion arranged around the rotating body 1. The cylindrical portion 8 is fixed on the base 2 and arranged around the rotating body 1. The cylindrical portion 8 has a circular inner cylindrical portion 9 facing the cylindrical portion 3 and the conical cylindrical portion 4 of the rotating body 1, a bottom portion 10 facing the lower end 3A of the cylindrical portion 3 of the rotating body 1, and a work opening laterally. An extraction hole 11 is provided. And the inner cylinder part 9 of the cylinder part 8,
An annular gap S about twice the thickness t of the work W is formed between the rotating body 1 and the cylindrical portion 3. Further, a second blade portion 12 facing the cylindrical portion 3 and the conical cylindrical portion 4 of the rotating body 1 is continuously formed in the inner cylindrical portion 9 from below to above. The second blade portion 12 includes a cylindrical portion 3, a conical cylindrical portion 4 of the rotating body 1,
It does not contact the first blade 7.

[0010] Then, the cylindrical portion 8 is fixedly arranged on the base 2, the rotating body 1 is arranged toward the inside of the cylindrical portion 8, and the rotating body 1 is rotatably arranged on the base 2. According to this, an annular gap S about twice the thickness t of the work W is formed between the inner cylinder 9 of the cylinder 8 and the inner cylinder 9 of the rotating body 1.

Reference numeral 14 denotes a cover for closing the upper opening of the cylindrical portion 8, and a work input hole 14 </ b> A opens in the cover 14.

Next, the removal of the workpiece W will be described with reference to FIG. A large number of works W are randomly inputted from a hopper (not shown) toward the conical cylindrical section 4 in the cylindrical section 8 through the work input hole 14A, and the rotating body 1 is rotated by the rotation source M in this state. According to this,
A large number of works W are randomly arranged on the projectile surface 5 of the conical tube portion 4, while the work W starts to descend downward on the projectile surface 5 by the gravity of the work W due to the rotation of the rotating body 1.

Looking at the state where the work W descends on the shell surface 5 of the rotating body 1, the upper part 5A of the shell surface 5 in FIG.
, Four works W overlap and exist.
In other words, any further workpiece W abuts on the second blade portion 12 due to the rotation of the rotating body 1 and scatters, and thus does not overlap and exist. Then, four overlapping works W existing on the upper part 5A of the shell surface 5 descend on the shell surface 5,
When reaching the middle portion 5B of the shell surface 5, the two workpieces W that overlap and exist on the outer side come into contact with the second blade portion 12 due to the rotation of the rotating body 1 and scatter, so that they no longer overlap. , And only two works W that do not abut the second blade portion 12 overlap and remain on the middle portion 5B of the shell surface 5. Then, when two further overlapping works W descend on the shell surface 5 and reach the lower part 5C of the shell surface 5, one work W overlapping outward is rotated by the rotation of the rotating body 1 to form the second blade portion. 12, and scatters, so that only one work W can no longer exist in the lower portion 5 </ b> C of the shell surface 5.

The work W, which is singly separated on the lower portion 5C of the shell surface 5, is formed into an annular shape formed between the cylindrical portion 3 of the rotating body 1 and the inner cylindrical portion 9 of the cylindrical portion 8. The vehicle descends and enters the gap S sequentially. Then, the gap S is defined by the work W
Formed at about twice the thickness t of the lower shell 5C of the shell surface 5.
In the above, the work W separated separately does not overlap,
It can be stored and arranged continuously and continuously in the annular gap S in a single state.

On the other hand, when the rotating body 1 rotates,
The single work W in the gap S descends due to its own gravity. When the work W faces the work take-out hole 11 formed in the cylindrical portion 8, the work W is automatically taken out. Are separated and discharged toward the conveying member 13. Then, as the rotating body 1 rotates, new works W sequentially reach the work take-out holes 11, so that the separated single work W is continuously and continuously discharged.
