JPS596881B2 - Automatic removal and movement device for powder molded products - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for automatically taking out and moving a powder molded product such as a sintered body that has been compression-molded into a predetermined shape by a mold, and particularly relates to a device for automatically taking out and moving a powder molded product such as a sintered body that has been compression-molded into a predetermined shape by a mold. The purpose of the present invention is to provide an automated device for removing and moving powder molded products that prevents breakage and cracking during removal and movement, and increases safety by automatically stopping the entire device in the event of an abnormality. It is something.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Practical paddles of the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2 are a side view and a plan view showing the apparatus of the present invention, in which reference numeral 1 denotes a lower die of a mold, on which a lower bante 2 and a lower pantainer 3 are installed, and an upper die (not shown) is raised and lowered. Accordingly, the powder filled in the lower die 1 is compression-molded to form the product A.

The powder filling shoe box 4 is taken out from the front with a fork 5
It is installed so as to be able to slide left and right on the shoe base 6.

The take-out fork 5 is attached to the front of the shoe box 4 so that it can be adjusted up and down, and is adjusted depending on the product A.

In addition, the shoe box 4 is formed after the product A is molded.
Move to the left on shoe base 6 and lower pante inner 3
While holding the product A pushed up by the shoe box 4 and moving further, when the shoe box 4 is positioned on the upper surface of the thousand-part die 1, powder material is introduced into the mold of the lower die 1 from an input port (not shown). ing.

Further, on the upper surface of the shoe base 6, on the opposite side of the shoe box 40 with respect to the mold, there is installed a moving device 7 using a link mechanism that takes over the product A from the take-out fork 5 of the shoe box 4 and transfers it to the next process or container. ing.

The moving device 7 using the link mechanism has a pivot point 8 on the base 8.
A main lever 10 is rotatably supported by a main shaft 9 at a point a, and an intermediate shaft 11 is supported at the other end of the main lever 10. A moving arm 12 is pivotably supported.

Further, on the main lever 10, a sliding rail 13 is attached to the main lever 10, which maintains a predetermined inclination angle and extends from the base 8 to the end of the arm 12. The width of the slide rail 13 can be arbitrarily adjusted by means of a fork width adjustment screw 14.

Further, an angle adjusting screw 15 for adjusting the inclination angle that the arm 12 forms with the shoe base 6 is installed at the end portion D of the arm 12 on the intermediate shaft 11 side.

Further, a slide 16 is installed at the left end of the base 8 to transfer the product A to the next process or container.

A limit switch 17 is installed on this slide 16 to confirm the passage of product 8, and when there is no passage of product 8 or when the limit switch 17 is in the ON/OFF state, It is linked to a safety device (not shown) that shuts down the entire device.

Next, the operation of the apparatus constructed as above will be explained based on FIGS. 3 to 5.

Figure 3 shows a state in which powder material is charged from the powder filling shoe box 4 and the product A, which has been compression-molded by the mold, is pushed upward from the lower die 1 of the mold by the rise of the lower pantainer 3. At this time, the shoe box 4 and the moving device 7 are stationary at the fixed position.
L is there.

Figure 4 shows product A until the lower pante inner 3 reaches the specified position.
When pushed up, the operating switch of the shoe box 4 operates, the shoe box 4 slides to the left, the take-out fork 5 holds the product A, and at the same time the lower vante inner 3
descends.

Further, the shoe box 4 slides and transfers the product A onto the slide rail 13 of the moving device 7, and confirms that the input port formed on the bottom surface of the shoe box 4 is positioned above the lower die 1 of the mold. Add the powder material.

In FIG. 5, the shoe box 4 into which the powder material has been charged is further slid to the left, and the arm 12 is pushed in at the end surface of the shoe box 4, causing the intermediate shaft 11 of the arm 12 to rise.

Simultaneously with the rise of the arm 12, the main lever 10 stands up while rotating at the pivot point 8a, and the slide rail 13 integrated with the main lever 10 changes its inclination angle into a seesaw state and receives the signal from the take-out fork 5. Shoot product A toward slide 16.

When product A slides down on the slide 16, a limit switch 17 is activated to confirm the passage of product 8 and to count the number of products.

The product A that has passed through the slide 16 is stored in the next culm or container, and the shoe box 4 retreats to its original position, completing one step.

At this time, the main lever 10 and arm 12 of the moving device 7 are also released from rising and are restored to their original set positions by their own weight.

In addition, if there is a problem in the operation of each part or damage to product A during the above process, and the limit switch 17 does not operate, or if the limit switch 17 remains activated, immediately repair the entire device. The main power source is cut off and operation stops.

In this case, a safety device is provided so that the entire device will not operate again unless a reset switch (not shown) is turned on after the cause of the trouble is removed.

As described above, according to the present invention, the removal and movement of powder molded products such as sintered bodies after compression molding is automated, which improves work efficiency, improves productivity, and prevents equipment abnormalities. Since it detects and prevents accidents, it does not damage the mold, making it a highly safe device.

In addition, the compression-molded powder molded product is pushed up from the lower die by the lower pantainer and taken out by the take-out fork completely away from the mold. There are no troubles such as damage to parts or cracks, and stable quality can be ensured with no product loss.
