PURPOSE:To take out a second work fitted into an annular first work easily and smoothly by providing a first pressing mechanism with which the second work is drawn out from the first work over a first recessed part on a transport mechanism. CONSTITUTION:A first work (outer rotor) 9 fitted with a second work (inner rotor) 10 is mounted on the recessed part 3 of a transport mechanism (rotary table) 2 and transported, and the second work 10 is drawn out from the inside of the first work 9 with a first pressing mechanism 11 at the recessed part 7 of the transport mechanism 2. Hereafter, the first work 9 is pushed out from the recessed part 3 with a second pressing mechanism 12 at the second recessed part 8 of the transport mechanism 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a work separation device that separates, for example, a ring-shaped outer rotor and a star-shaped inner rotor of an internal gear pump.

[Conventional technology]

For example, both end surfaces of a ring-shaped outer rotor and a star-shaped inner rotor of an internal gear pump are polished on both ends with the inner rotor fitted into the outer rotor.

[Problem to be solved by the invention]

By the way, when both end surfaces of the outer rotor and the inner rotor are polished as described above, there is a problem in that it is difficult to smoothly remove both rotors after polishing due to the burrs generated by the polishing. Conventionally, the inner rotor has been removed from the outer rotor manually, but this method is time consuming and has poor workability.

The present invention has been made in view of the above circumstances, and its purpose is to provide a ring-shaped first workpiece fitted into a ring-shaped first workpiece, such as an outer rotor and an inner rotor of an internal gear pump. It is an object of the present invention to provide a workpiece separation device that can easily and smoothly remove a second workpiece and greatly improve work efficiency.

[Means to solve the problem]

In order to achieve the above object, the workpiece separation device of the present invention includes a transport mechanism that transports the second workpiece by fitting it into a recess in a state where the second workpiece is fitted into the inside of the first workpiece; a first recess provided in the transport mechanism and formed larger than the inner diameter of the first workpiece and smaller than the outer diameter of the first workpiece; and a first recess provided above the first recess and configured to hold the second workpiece. is extracted from the first workpiece.
a second recess provided in the transport mechanism and formed larger than the first workpiece; and a second recess provided above the second recess for pushing the first workpiece out of the recess. It is equipped with the following suppression mechanism.

[Effect]

In the workpiece separation device of the present invention, the first workpiece into which the second workpiece is fitted is mounted in the recess of the transport mechanism and transported, and the first workpiece is pressed in the first recess of the transport mechanism. After the second workpiece is extracted from the inside of the first workpiece by the mechanism, in the second recess of the transport mechanism, the first workpiece is pushed out of the recess by the second pressing mechanism.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 6.

In FIGS. 1 to 6, reference numeral 1 denotes a belt conveyor, and a rotary table 2 is rotatably provided at the exit of the belt conveyor 1.

The outer circumference of this rotary table 2 is spaced at equal intervals of 4ft! ! An arc-shaped recess 3 of I is formed, and the rotary table 2
A rotation mechanism 4 for intermittently rotating the rotary table 2 every 90° is arranged below the rotary table 2 . Further, an arc-shaped guide 5 is arranged outside the rotary table 2. A base 6 is installed below the rotary table 2, and through holes 7 and 8 are provided in the base 6 at positions 90° and 180° away from the outlet of the belt conveyor 1, respectively. It is formed.

The through hole 7 is formed to be larger than the maximum inner diameter and smaller than the outer diameter of the ring-shaped outer rotor (first workpiece) 9. Further, the through hole 8 is formed to be larger than the outer diameter of the outer rotor 9. Pressing tools 11 and 12 are provided above the through hole 7.8 of the base 6, respectively, so as to be able to rise and fall freely.
．． Pressure cylinders 13 , 14 carrying 12 are each arranged above the base 6 . Furthermore, the base 6
Below each through hole 7.8 is a chute 15.1.
6 is placed.

In the work separation device configured as above, the star-shaped inner rotor (second work)! 0 is inserted into the outer rotor 9, both rotors 9. The IO is transported and installed in the recess 3 of the rotary table 2. Next, the rotary table 2 is rotated 90 degrees counterclockwise in FIG. 13 is lowered, and the pressing tool 11 presses the inner rotor 10 downward, extracts it from the outer rotor 9, and discharges it from inside the through hole 7 onto the chute 15 below.

Subsequently, the rotary table 2 is rotated 90 degrees counterclockwise in FIG. The pressing tool 12 of the cylinder 14 is lowered, and the pressing tool 12 pushes the outer rotor 9 out of the through hole 8 and shoots it downward! 6 Pay out on top.

〔Effect of the invention〕

As explained above, the work separation device of the present invention has the first
a conveyance mechanism that attaches and conveys the second workpieces in the recesses in a state in which the second workpieces are fitted inside the workpieces; a first recess formed smaller than the outer diameter of the work; a first pressing mechanism provided above the first recess for extracting the second work from within the first work; and a transport mechanism. a second recess provided in the recess and formed larger than the first work; and a second suppression mechanism provided above the second recess for pushing the first work out of the recess. Therefore, the first workpiece fitted with the second workpiece is mounted in the recessed part of the transporting mechanism and transported, and the second workpiece is pressed by the first pressing mechanism in the first recessed part of the transporting mechanism. After the workpiece is extracted from the inside of the first workpiece, the inside of the ring-shaped first workpiece is pushed out by the second suppression mechanism in the second recess of the transport mechanism. The second workpiece fitted into the second workpiece can be easily and smoothly removed, and work efficiency can be greatly improved.
