The window opening / closing mechanism 4 configured as described above is
In the state where the cam follower 48 is in contact with the lower end surface of the cam surface 11d of the rotating base frame 11 shown in FIG.
The vertical operating rod 46 shown in FIG. 4 swings about the swing support shaft 54, and the upper operating pin 49 is positioned at the lower end position against the cam urging spring 50 shown in FIG. On the other hand, the vertically moving plate 40 is moved downward by being urged by the lower urging spring 52, and its lower end position is located at the opening / closing guide groove 30 of the relay flow path body 30.
The opening and closing plate 42 screwed upward is abutted on the lower side surfaces of the upper and lower operation holes 40c and 30d, and is positioned with a gap formed between the upper end of the upper operation hole 40c and the upper operation pin 49. Then, the discharge window 10d is closed by the opening / closing plate 42.

Further, as the rotating base frame 11 rotates, the relative height of the cam surface 11d contacting the cam follower 48 changes from the lower end surface position shown by the solid line in FIG. 7 to the upper end surface side shown by the two-dot chain line. Then, the upper operation pin 49 is urged by the cam urging spring 50, and the cam follower 48 moves up,
Further, the vertical operating rod 46 swings clockwise about the swing support shaft 54, and the vertical moving plate 40 is moved upward by the upper operating pin 49 contacting the upper end of the upper operating hole 40c.

When the cam follower 48 is in contact with the rising end face of the cam surface 11d, the vertically moving plate 40 is positioned at the upper end together with the opening / closing plate 42 as shown in FIG. Be released. In addition, the lift of the cam surface 11d (the maximum displacement between the lower end surface shown by the solid line in FIG. 7 and the upper end surface shown by the two-dot chain line) is the same as that in FIG. It is formed so as to be swingable between a lower end position shown and an upper end position shown in FIG.

The front end 43b of the third rod 43 abuts to prevent the forward movement, and the piston operating rod 44 is stopped. When the piston operation rod 44 is stopped, the vertically movable plate 40 engaged with the piston operation pin 45 cannot move upward together with the open / close plate 42, so that the exit of the discharge window 10d is closed by the open / close plate 42, Even if the next work W is transferred into the discharge window 10d, it is forced to wait without being discharged from the exit.

In this way, even if the vertical moving plate 40 cannot move upward, the rotating base frame 11 shown in FIG.
As shown in FIG. 12, even after the piston operating rod 44 is stopped, d is displaced from the slope for raising the cam follower 48 toward the rising end face. However, the cam followers 48 are not in contact with the cam surface 11d because the upper operation pins 49 that engage with the vertical moving plate 40 are suppressed, and a gap is formed between the cam followers 48. Therefore, the vertical movement plate 40 is not subjected to an unreasonable action for moving upward by the upper operation pin 49.

For example, the present invention can be carried out even if the center rotating bottom of the container rotating body is formed flat, and the relay channel mechanism and the window opening / closing mechanism can be carried out in various forms depending on the shape of the work to be used. .

[0091]

Since the present invention has been made as described above, it has the following effects.

According to the first aspect of the present invention, a plurality of vertical guide grooves are formed in the outer frame of the container, and the work is circulated from the inner wall side to the outer wall side and discharged near the upper end crossing each of the vertical guide grooves. Since a plurality of possible discharge windows are formed, the work placed on the inclined mounting surface of the container rotating body is raised along the vertical guide groove, and is sequentially dropped from each discharge window. There is an effect that the workpiece can be distributed and supplied to a plurality of supply destinations through the respective discharge paths provided below the discharge window.

According to the second aspect of the present invention, the plurality of vertical guide grooves are formed as concave grooves into which a cylindrical or columnar work axis can be fitted in a lateral direction. This has the effect that the work having the shape of a column or a column can be discharged from the respective discharge windows of the outer frame of the container in a horizontal position.

According to the third aspect of the present invention, the upper surface of the bottom of the container rotating body is formed as a conical inclined surface having the apex of the axis of the cylindrical peripheral wall as a vertex, so that the direction of disorder can be improved. Thus, there is an effect that the work stored in the step (1) can be easily moved to the peripheral edge of the container rotating body, and can be placed on each inclined mounting surface of the container rotating body.

According to the fourth aspect of the present invention, the bottom of the container rotator includes a rotatable conical central rotation bottom,
Since it is divided into a non-rotatable frustum-shaped peripheral edge fixed bottom part, the work stored in a random direction can be easily moved to the peripheral edge of the container rotating body, and each inclined mounting surface of the container rotating body. And the mounted work can be easily fitted into the respective vertical guide grooves of the container outer frame.

According to the fifth aspect of the present invention, an upstream expansion channel through which the workpiece can be received and circulated is formed in the vicinity of the outlet of the discharge window. A direction change flow path whose width is gradually reduced is formed, and between the lower part of the direction change flow path and the supply path of the supply destination,
Since the relay flow path body formed with the downstream vertical flow path so that the work can flow in the vertical direction is provided, each work discharged from the discharge window is moved from the horizontal direction along the gradually changing direction change flow path. Thus, there is an effect that the direction can be changed in the vertical direction and supplied to the supply path.

According to the sixth aspect of the present invention, since the relay flow path body is provided with two sorting pedestals laterally on both left and right sides of the upstream expansion flow path, the work having a different diameter falls laterally. By contacting both ends of each of the separation pedestals with the respective separation pedestal, it is possible to supply the work to the supply path by defining the small-diameter side end of the different-diameter work passing through the small-diameter end passage groove of the separation pedestal in the downward set supply direction. It has the effect of being able to.

Further, according to the seventh aspect of the present invention, the relay channel body has the sorting pin erected at a substantially central position in the lateral direction of the upstream expanding channel, so that the eccentric work dropping sideways. The center of the abutment comes into contact with this sorting pin, and by the principle of lever balance that makes the center of the eccentric work a fulcrum,
There is an effect that the work can be supplied to the supply path by defining the large-weight side end of the eccentric work in the downward set supply direction.

According to the eighth aspect of the present invention, if the work previously supplied to the supply path is stagnant and the previous work is stagnant in the downstream vertical flow path of the relay flow path body, the stagnant work is stopped. The piston abuts on the workpiece that is moving and restrains its forward movement,
Since the piston operating rod is stopped, the vertical moving plate that is urged upward by the cooperation of the cam urging spring and the vertical operating rod that pivotally mounts a cam follower that contacts the cam surface of the container rotating body is formed. Since it is impossible to move upward, the exit of the discharge window is closed by the opening / closing plate attached to this vertical moving plate so that the next work is not discharged from the discharge window even if it is transferred into the discharge window. This has the effect that it can be performed.
