Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for transferring a powder compression-molded product obtained by compression-molding a raw material for a powder or granular material into a columnar shape.

2. Description of the Related Art As shown in FIG. 10, a powder compression molded body 1 which is compression molded into a column shape by a molding machine is transferred to a sintering tray 2 and an industrial robot compresses the powder at a position before the sintering tray 2. The compacts are picked up and aligned on the sintering dish 2. The sintering dish 2 on which the transfer of the powder compression molding 1 is completed is sent to the next sintering step 3.

FIG. 11 shows a molding machine. The raw material 4 is put into the filling hole 5 as shown in FIG. 11 (a), and the raw material 4 is fed into the filling holes 5 by the upper and lower punches 6a and 6b.
Compression molding is performed as shown in FIG. Then, as shown in FIG. 11 (c), the punch 6a is pulled up to the outside of the filling hole 5 and the punch 6b is pushed up to the upper surface 8 of the die 7 to push up the powder compression-molded body 1 which is compression-molded and then pushed out from the side. The pusher 9 transfers the powder compression molding 1 on the upper surface 8 toward the sintering dish 2.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional configuration, since the powder compression molded body 1 is pushed and transferred by the pusher 9 in the vertical position, the height of the powder compression molded body 1 is about 1.5 times the bottom side. If it exceeds the range, the powder compression-molded body 1 is likely to fall down during the transfer as shown by the phantom line in FIG. 11 (c).

Thus, the powder compression molded body 1 which has fallen to the lateral position in this way
Alternatively, if the powder compression molded bodies 1 that have been normally transferred and are in the vertical position are mixed, it becomes difficult to perform the alignment transfer to the sintering plate 2 and the transfer process to the sintering plate 2.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transfer device capable of aligning and transferring a powder compression molding having a height exceeding 1.5 times the bottom.

Means for Solving the Problems The powder compression molded article transfer device of the present invention is provided with passage walls on both sides of a transfer path of a columnar powder compression molded article sent out on a transfer surface in a vertical position. A first protrusion is provided on the transfer surface at the entrance of the transfer path formed between the powder compression moldings during transfer, and the first projection is lifted up against the transfer surface and the powder compression moldings are pushed backward to move through the transfer path. A movable body that is driven to move horizontally is provided, and on the back surface of the movable body,
The present invention is characterized in that a second protrusion is formed so as to contact only the upper part of the upper and lower parts of the powder compression molded body in the vertical position.

Operation According to this configuration, the movable body pushes the powder compression molded body in the vertical position to the position of the first protrusion, and the upper portion of the powder compression molded body whose sliding movement is restricted by the first protrusion. Is further pushed by the second protrusion of the movable body to positively tilt the powder compression molded body to the horizontal position, and the powder compression molded body in the horizontal position is further pushed by the movable body to be further transferred.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. It should be noted that components having the same functions as those in FIGS. 10 and 11 showing the conventional example will be described with the same reference numerals.

1 to 6 show the structure of the transfer device of the present invention and the transfer process thereof. As shown in FIG. 2, the movable body 10 descends to a position above the powder compression-molded body 1 which has been compression-molded and pushed out by the pusher 9 on the upper surface 8 as a transfer surface in a vertical position. The movable body 10 descending in the direction of arrow A from above is
It is horizontally driven in the direction of arrow B as shown in FIGS.
As shown in FIG. 8, passage walls 11a and 11b are provided on both sides of the transfer route.
Is formed, and a first protrusion 13 is formed on the upper surface 8 of the inlet of the transfer passage 12 formed between the passage walls 11a and 11b. As shown in FIG. 2, the upper end portion of the backing surface 14 of the movable body 10 which is horizontally driven in the direction of the arrow B to push the powder compression molded body 1 abuts only the upper portion of the powder compression molded body 1 in the vertical position. The second protrusion 15 is formed, and the second
The powder compression molded body 1 in the vertical position at the position shown in the figure slides on the upper surface 8 because the upper part thereof is first pushed by the second protrusion 15 of the movable body 10. The powder compression molding 1 in the vertical position has the first protrusion 13
When the slide compression state is reached, the slide state is blocked by the first protrusion 13 and the upper portion of the powder compression molded body 1 pushed by the second protrusion 15 tilts as shown in FIG. As shown, it collapses into the transfer passage 12 in a horizontal position. The powder compression molded body 1 in the horizontal position is pushed by the back pushing surface 14 of the movable body 10 as shown in FIG. 5 and further slid and transferred in the direction of the arrow B, and the pallet continues to the upper surface 8 as shown in FIG. Pushed into 16. The pallet 16 on which the transfer of the powder compression molding 1 is completed descends in the direction of arrow C as shown in FIG. 7, is placed on the conveyor 17 and is transferred toward the sintering tray 2, and the industrial robot [ (Not shown) picks up the powder compression molded body 1 in the horizontal position and sets it in the vertical position to align it on the sintering tray 2.

In this embodiment, the tip shape of the pusher 9 is formed on an arcuate surface 18 along the shape of the powder compression molding 1 as shown in FIG. The pusher 9 is formed on the bottom of the guide walls 19a and 19b extending from the passage walls 11a and 11b and the upper surface 8 of the guide walls 19a and 19b.
It is extruded along the groove 20 between them, and the pusher 9 and the guide walls 19a, 19b hold the powder compression-molded body 1 so as not to fall to the rear body or sideways, and reach the position of the first protrusion 13. Pushing out.

In this way, while the powder compression molded body 1 is transferred to the pallet 16 by being pushed by the movable body 10, the powder compression molded body 1 in the vertical position is horizontally moved by the first protrusion 13 and the second protrusion 15. Since the posture is changed to, the powder compression molded bodies 1 that are compression molded at the same time can be aligned and transferred as shown in FIG. 7, and the transfer processing to the sintering tray 2 becomes easy.

In the above embodiment, the second protrusion 15 is formed integrally with the movable body 10. However, this is formed by attaching a member such as a leaf spring formed separately from the movable body 10 to the movable body 10. Is also the same.

As described above, according to the present invention, the first surface formed on the transfer surface
And the second protrusion formed on the movable body can change the vertical position of the powder compression molded product to the horizontal position, and the ratio of height to base is 1.5 times or more. Also,
Since the compressed powder compacts can be aligned and transferred at the same time, transfer processing to a sintering dish or the like can be facilitated.
