Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a parts storage device that automatically takes out and transports manufactured parts, and more specifically, the present invention relates to a parts storage device that automatically takes out manufactured parts and transports them. The present invention relates to a device for storing a molded product continuously pressure-molded into a predetermined shape in a container.

[Conventional technology]

Traditionally, molded products that have been compression-molded into a predetermined shape by the mold of a powder molding machine are taken out and transported, either completely by hand or partially using machines. .

Firstly, this method is all done manually, and in this method, the molded products that are sequentially sent out from the powder molding machine are packed in fixed quantities into a container such as a container. Next, containers filled with a certain number of molded products are stacked in multiple tiers, and finally, when the stacked containers reach a certain number, they are transported to the next process, all of which are performed manually. I was getting used to it.

The second method uses some machines, but among the above-mentioned methods that are all done manually, the method uses a method in which a plurality of containers each filled with a fixed number of molded products are stacked in a multi-tiered row. The products are automatically transported to the next process using a sequential conveyor.

[Problem to be solved by the invention]

However, the conventional method and apparatus for taking out and transporting a molded product compression-molded into a predetermined shape using a mold of a powder molding machine has the following problems.

First of all, the speed at which the molded products molded by the powder molding machine are delivered is fast, so if the molded products were packed into containers manually, it would be impossible to keep up with the speed.
It was not possible to store the molded products directly from the powder molding machine into a container, such as by temporarily pooling the molded products delivered from the powder molding machine in a large container. In addition, since the operating speed of the powder compacting machine is controlled according to the processing capacity of the operator, it is not possible to maximize the operating efficiency of the machine.

Furthermore, when the filling work was done manually as in the past, the number of molded products to be packed into the container had to be left to the empirical judgment of the worker. For this reason, it is not possible to accurately pack a fixed number of molded products into containers, resulting in considerable variation in the number of molded products packed into containers.

Furthermore, in the process of packing molded products sent out from a powder molding machine into a container, whether the powder molded product is directly stored in a container or once pooled in a large container, the stretched molding from the powder molding machine Cracks and chips may occur in the molded product due to the molded product being sent out from the product discharge port falling onto the container, or during the process of transferring it from a large pooled container to a separate storage container, resulting in defective products. Occasionally, this may occur.

As explained above, the conventional method and equipment for taking out and transporting a molded product that has been compression-molded into a predetermined shape using the mold of a powder molding machine has many problems, so powder molding There was a strong desire to fully automate the series of devices used to store items.

However, it is not possible to count the number of molded products to be packed into a container to be constant, the dimensions, shapes, and materials of molded products vary widely, and storage methods are diversifying, such as bulk packaging, aligned packaging, and multi-tiered stacking. Therefore, it has been difficult to fully automate powder molded product storage equipment because such measures cannot be taken when mechanizing.

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention aims to fully automate a series of devices for storing powder molded products.
