Therefore, it is not necessary to interrupt the molding operation by the molding machine because the molded product is not temporarily stored and scattered around.

By the way, in order to accommodate a molded product produced by a molding machine (not shown), the accommodating container 15 is conveyed toward the sample collecting device 1 described above. The container 15 includes a container body 16 and a container body 1.
6, a lid body 17 covering the upper surface opening is provided.
At the bottom of the chute guide 11, there is formed an inlet 17a that can communicate with the lower end of the chute guide 11. And this input port 1
7a is provided with a recessed portion having an inverted hat cross section, and a small lid 19 on which a bolt 18 as a holding member is erected is attached. This bolt 18 has a small lid 19
It is formed to be slightly shorter than the depth of the small lid 19 so as not to project upward from the brim portion (see FIG. 3).

In this embodiment, the storage container 15 in which the small lid 19 can be attached to and detached from the insertion port 17a formed in the lid 17 is shown, but the lid 17 can be attached to the lid 17 without using the small lid 19. The recesses may be directly formed in a part or the whole. In this case, the bolt 18 may be fixed to the recess formed in the lid body 17.

Such a container 15 has a frame 20.
It is conveyed toward the sample collecting device 1 via the conveying device installed in the above, specifically, a pair of chain conveyors 21 and 21. A stopper 22 is fixed to the frame 20 to position the conveyed container 15.

Next, the operation of this embodiment will be described.
By driving the chain conveyors 21 and 21, the chain conveyors 21 and 21 are driven via a lift device (not shown).
The storage container 15 placed on 1 is conveyed toward the sample collecting device 1. Then, the container 15 becomes the stopper 22.
If it comes into contact with, the driving of the chain conveyors 21 and 21 is stopped and the container 15 is positioned immediately below the supply port of the chute 12. After that, when the air cylinder 5 is extended and the elevating frame 6 is lowered, the chuck device 7 causes the small lid 19 to move.
It descends to a position sandwiching the bolt 18 erected on. Then, if the chuck device 7 is operated, the bolt 18 can be grasped. After that, when the air cylinder 5 is contracted, the small lid 19 is pulled up from the insertion opening 17a formed in the lid body 17 and removed. Then, when the rotary actuator 3 is driven, the revolving frame 4 rotates, and the chuck device 7 holds the small lid 19 and rotates the guide plate 10 while slidingly contacting the lower end of the chute 12. When the guide plate 10 rotates by the set angle, the chute 12
The supply port of the guide plate 10 is the opening 10a, and the chute guide 11 is provided in the lid 17 through the charging port 17a.
Can be connected to.

During this time, the lower end of the chute 12 of the molded product molded by the molding machine (not shown) is the guide plate 10.
It is stored in the chute 12 because it is closed by. Then, the opening 1 of the guide plate 10
If the supply port of chute 12 communicates with 0a, chute 1
The molded product stored in the mold 2 and the molded product sent from the molding machine thereafter are the opening 10a and the chute guide 1.
First, it is supplied to the inside of the container body 16 of the storage container 15 through the input port 17a of the lid 17. As a result, the storage container 15
It is not necessary to interrupt the molding operation by the molding machine at the time of replacement, and at that time, it is possible to prevent a decrease in yield due to scattering of these molded products around and being discarded as defective products.

As described above, when the molded product is supplied to the storage container 15 through the chute 12 and reaches a predetermined number, the chain conveyors 21 and 21 are slightly driven in the reverse direction to return the storage container 15 and then again. Chain conveyor 21,21
Is driven in the forward direction to convey the storage container 15 toward the stopper 22 and collide with it. By performing such a reciprocating movement, the molded products piled up in a heap shape inside the container body 16 are leveled, and as a result, the accommodation space of the accommodation container 15 can be efficiently used.

When the set quantity of molded products is supplied, the rotary actuator 3 is driven in the opposite direction to the above to rotate the guide plate 10 to close the supply port of the chute 12, and at the same time, the small lid 19 is closed. The insertion port 17a of 17 is rotated to a position facing. Next, when the air cylinder 5 is extended, the small lid 19 is attached to the insertion port 17a of the lid body 17. After that, the chuck device 7 is operated to operate the bolt 18

Then, the rotary actuator 3 is driven again to rotate the opening 10a of the guide plate 10 to a position where the small lid 19 is exposed. During this time, the molding machine performs one-shot or multiple-shot molding of the molded product, and supplies the molded product to the concave portion of the small lid 19 via the supply port of the chute 12, the opening 10a, and the chute guide 11. The molded product supplied to the small lid 19 becomes a sample of the molded product molded up to that time and supplied to the storage container 15.

When the collection of the sample is completed, the chain conveyors 21 and 21 are driven in the reverse direction to convey the container 15 to an appropriate storage location. Then, these storage containers 15 are transported to the inspection department, and by inspecting the sample stored in the small lid 19, it is possible to estimate the quality of the molded product stored in the storage container 15.
At this time, the sample is associated with the storage container 15 in advance and is taken out of the storage container 15, so that it is not necessary to remove the lid 17 to collect the sample.

On the other hand, when the storage container 15 in which the set quantity of molded products is stored is carried out, a new storage container 15 is carried in through the chain conveyors 21 and 21, and similarly the supply of the molded products is started. ..

In this case, the sample is accommodated in the concave portion of the small lid 19, and the bolt 18 does not project from the upper surface of the lid body 17. Therefore, when the accommodation container 15 is conveyed, there is no problem even if other accommodation containers 15 are stacked. And no special handling is required.

In this embodiment, the case where the molded product is supplied from the molding machine has been described, but the present invention is not limited to the molded product.

Further, in the present embodiment, the product is supplied through the chute, and the supply of the product is controlled by the guide plate when the storage container is replaced. However, instead of the guide plate, the product is directly supplied to the chute. A shutter can also be provided. When the product is supplied via a conveyor instead of the chute, the conveyor may be provided with a shutter, or the driving of the conveyor may be temporarily stopped to interrupt the supply of the product.
