Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a powder compact for automatically loading a cylindrical compact formed by a powder compacting machine into a box such as a sintering container. Related to automatic packaging equipment.

[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 defects or cracks will occur in the molded product during the filling operation into the sintering container or during transportation. It is necessary to pay close attention to this, requiring labor and time, and there are various problems in automating it.

Therefore, in order to load a cylindrical molded product such as the powder molded product mentioned above into a container, an array of aligned pellets or a group of arrayed pellets in an upright position or an inverted position is lifted and conveyed by vacuum suction and placed in a predetermined container. It has also been proposed to load the
132228, Japanese Patent Application Laid-Open No. 57-52896). However, in the case of compacts that require sintering, the dimensions of the compacts vary due to differences in the sinterability of the powder, etc., so the suction head of the vacuum suction device is There are problems such as having to replace the

In addition, when storing a group of compacts that have been adsorbed and transported by the vacuum suction device into a sintering container, a plurality of compacts can be placed in the container by repeating suction, transport, and release multiple times. However, since the molded bodies are cylindrical, simply releasing the suction does not necessarily stack the molded bodies in an orderly manner, resulting in poor stability and the molded bodies colliding with each other during transportation, resulting in damage. Therefore, it is necessary to pay sufficient attention to the stacking.

Therefore, loading the powder molded product into a container 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 makes it possible to orderly load molded objects of different sizes into a container using the same suction head without changing the suction head.
An object of the present invention is to provide an automatic boxing device for molded objects that can automatically fill containers with molded objects without any manual intervention and without causing defects, cracks, etc. in weakly strong molded objects. .

(see figure).

On the other hand, the suction head 106 is moved above the group of compacts arranged on the alignment table 8 by the horizontal movement of the suction head traversing block 94, and there, the suction head support block 103 is moved by the drive motor 1.
04, the suction head 106
is brought into contact with the upper surface of the group of molded objects, and the group of molded objects is attracted to the lower surface of the suction head 106 by the operation of the suction device. In this case, a spring 1 is installed between the suction head 106 and the suction head support block 103.

transported to. Therefore, by tilting the suction head tilting block 97 by about 10 degrees using the actuating cylinder 99, the same as the sintering container, the suction head 106 is made to match the inclination of the sintering container 110. The suction head 106 is lowered to near the bottom, suction is stopped, and the molded article is separated from the suction head 106 (FIG. 11). Then, since the sintering container 110 is tilted, the green bodies roll toward the lower side of the sintering vessel 110, and one side of the green body row comes into close contact with the inner surface of the side wall as shown by the dotted line. sent to.

In this way, the first stage molded body becomes the sintering container 1.
10 is filled, the suction head 106 is raised and the same operation is repeated in order to suction the next molded object. Therefore, when loading the second stage of compacts, the suction head 106 is stopped at a position one pitch higher than the bottom, and the compacts are separated from the suction head 106 at that position, so that the compacts can be loaded onto the bottom stage. The green bodies are deviated from the apex of the rows and fall into the valleys between the rows of green bodies, so that the green bodies 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 sintering containers may be deformed as they pass through a high-temperature furnace, it has conventionally been necessary for workers to sort them. However, in this embodiment, if a deformed container happens to be transported to the forming volume loading position, when the suction head 106 is lowered as described above, as shown in FIG. The suction head 106 comes into contact with the deformed sintering container 110, and further descent is prevented. Therefore, the suction head 106 rises relative to the suction head support block 103, which continues to descend, and the pin 108 protruding from the suction head 106 comes into contact with the sensor 109, and the signal causes the suction head to move upward. The descent of the container 106 is stopped, and the deformed container is automatically removed from the line as unusable by a removal mechanism (not shown). 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 transferred to the sintering container conveyor 11.
The net weight of the container filled with molded bodies is measured in the same way as for an empty container.
Then, the measured signal is input to a calculator, and the total weight of the molded body is calculated from the difference between the signal and the weight of the empty container measured in advance.

The sintering container containing the compact having 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 weight, total weight) and compact density, which are the data during automatic handling, or the lot number, line number, etc. that must be entered in advance using the keypad, are stored in the sintering container containing the compact. An information card is created that records the necessary information.

〔Effect of the invention〕

Since the present invention is configured as described above, when a row of molded bodies in an upright position are arranged in a 90° reversal unit in a fallen position at regular intervals, each molded body engages with the chevron of the 90° reversal plate. Even if the dimensions of the molded object change to some extent, the pitch between the rows of the molded object remains constant, and the suction head of the vacuum suction transfer device can reliably adsorb the group of molded objects, making it easy to remove the suction head. There is no need for troublesome work such as replacement. Further, when storing the group of molded bodies transferred by the suction head in a container for sintering, the suction head and the container are placed in a predetermined position around an axis parallel to the axis of the molded body adsorbed by the suction head. By tilting the angle, the compacts are automatically stacked in bales when loaded into containers, improving the stability of the stacked compacts and preventing them from colliding with each other during transportation. No defects occur, and the filling performance in the container is improved. Furthermore, the suction head is suspended from the suction head support block at a predetermined interval, and when the suction head moves up by a certain amount with respect to the suction head support block, the upward movement is detected. Deformation of the sintering container can be detected when the suction head is lowered, and unusable containers can be automatically removed.

As described above, according to the present apparatus, it is possible to completely automate the filling operation of the molded body discharged from the powder molding machine into the container.
