Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to V) final molding for automatically loading a cylindrical molded body formed by a powder molding machine into a box such as a sintering container. This invention relates to an automatic body packaging device.

[Technical background of the invention and its problems]

Generally, when sintering a powder molded product, the molded product formed by a powder molding press is filled into a sintering container, and then carried into a sintering furnace and sintered there.

However, since the strength of the powder molded product before sintering is low, there is a high possibility that the molded product will be damaged or cracked during the filling operation into the sintering container or during transportation. It is necessary to be very careful about this, and it requires labor and time, and there are various problems in automating it.

Therefore, in order to fill a container with a cylindrical molded product such as the powder molded product described above, a row of aligned pellets or a group of rows of aligned pellets in an upright or fallen position is lifted and conveyed by vacuum suction and placed in a predetermined container. Loading has also been proposed (JP-A-56-132228, JP-A [fi35]).
7-52896). However, in the case of compacts that require sintering, the dimensions of the compact are close due to the close sinterability of the powder, etc., so depending on the change in dimensions, the suction of the vacuum suction device is applied each time. There are problems such as the need to replace the head.

In addition, in order to sinter powder molded products, the sintering container that houses the molded product is often deformed as it passes through a high-temperature furnace. You need to check the dimensions before doing so. Furthermore, when measuring the weight after loading in this type of molded product packaging equipment, the capacity type measures the total weight of the molded products inside, and in many cases, the weight of the empty container is determined in advance. The net weight is determined by subtracting the weight from the total 1ffl measured value.

However, since the weight of this sintering container is constantly changing due to the influence of the atmosphere in the sintering furnace, it is necessary to measure the weight in advance each time.

Therefore, loading powder molded products into containers for this purpose requires many troublesome steps and requires a large number of workers.

[Purpose of the invention]

In view of these points, the present invention enables molded objects of different sizes to be loaded using the same suction head without changing the suction head, and also allows for the deformation of containers and the measurement of individual empty containers and filled reservoir containers. , it is possible to automatically measure during the process of loading molded bodies into containers, and the molded bodies are automatically filled into containers without human intervention and without causing defects or cracks in weakly strong molded bodies. An object of the present invention is to obtain an automatic packaging device for molded articles that can perform the following steps.

[Summary of the invention]

A screw @105 that is rotationally driven by
can move up and down along the guide rod 102.

Furthermore, below the suction head support block 103, a suction head 106 is mounted on the suction head support block 103.
It is mounted so that it can move up and down to a certain extent relative to 3.

A spring 107 is placed between the head support block 103 and the sucking head support block 103.
Since the suction head 106 is interposed, a buffering effect acts on the suction head 106, and the molded body is prevented from being damaged due to the suction head 106 coming into contact with the molded body.

When the molded bodies are attracted to the suction head 106 as described above, they are lifted upward together with the suction head support block 103, and are conveyed to the molding volume loading position U10 by the movement of the suction head traverse block 94. Therefore, by tilting the suction head tilting block 97 by about 10 degrees using the actuating cylinder 99 in the same manner as the sintering container, the suction head 106 is made to match the inclination of the sintering container 110.
Furthermore, the suction head 10 reaches the vicinity of the bottom of the sintering container 110.

Then, since the sintering container 110 is tilted, the molded bodies roll toward the lower side of the sintering container 110, and one side of the molded bodies is brought into close contact with the inner surface of the side wall as shown by the dotted line 1. Depends on the condition.

When the first-stage molded bodies are filled into the sintering container 110 in this manner, the suction head 106 is raised and the same operation is repeated in order to attract the next molded body. Therefore,
When loading the second stage of compacts, the suction head 106
is stopped at a position one pitch higher than the bottom, and when the molded body is moved from the suction head 106 at that position, the molded body shifts from the apex of the row of molded bodies at the bottom and falls into the valley between the rows of molded bodies. As a result, the compacts are stacked in stable bales. By repeating such operations, the molded articles can be filled into the container in an orderly and efficient manner.

By the way, since the sintering container passes through a high-temperature furnace, it may be deformed, so conventionally it was necessary for an operator to sort the container. However, in this embodiment, if a deformed container happens to be transported to the molding/volume loading position,
As mentioned above, when the @ deposition head 106 descends, the 12th
As shown in the figure, the suction head 106 comes into contact with the deformed sintering container 110, and further lowering is prevented.

Therefore, continue descending (pull the suction head support block 1

J--109, and the suction head 1 is activated by the signal.
06 is stopped, and the deformed container is automatically taken out of the line by an unillustrated extraction mechanism as unusable. Therefore, it is not necessary to strictly check the deformation of the container in advance.

When the filling of the compact into the sintering container 110 is completed as described above, the sintering container 110 is returned to the horizontal state and placed on the sintering container conveyor 11, and the empty As in the case of containers, the net weight of the container filled with the molded body is measured.

The measured signal is also input to a computer, and the total weight of the molded body is calculated based on the difference from ff1ffl of the empty container, which has been measured in advance.

The sintering container containing the compact that has been measured is again placed on the sintering container conveyor 11, and transported by the conveyor to a predetermined location for the sintering operation.

In this case, the container weight (empty container single, total distance ♀) and compact density, which are the data during automatic handling, or the loft number, line number, etc. that are entered manually in advance, for sintering with compacts. An information card is created that records the necessary information on the container.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to automatically measure the dimensions, FL and density of the molded product, and the weight of the container during the packaging process of the molded product without any manual intervention.
It is possible to save labor. Moreover, since the rows of molded bodies in an upright position are arranged in an inverted position at regular intervals by a 90' inversion unit, even if the dimensions of the molded bodies change to some extent, the pitch between the rows of molded bodies is always constant. The suction head can reliably suction the molded bodies, and there is no need to perform troublesome work such as replacing the suction head. Further, when the empty sintering container and the suction head are tilted at a predetermined angle, the molded bodies in the container are automatically stacked in bales during loading operation, improving stability and filling performance. Furthermore, the suction head is suspended from the suction head support block at a predetermined interval, and when the suction head moves above a certain value with respect to the suction head support block, the upward movement is detected. Deformation of the sintering container can be detected when the head is lowered, and unusable containers can also be automatically removed.
