BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a static electricity removing and cooling device for a disk-shaped injection molded product used as a recording medium such as a floppy disk or a compact disk.

[0002]

2. Description of the Related Art This type of disc-shaped injection-molded article is molded by an injection molding machine installed in a clean room, and then subjected to static electricity removing processing and cooling processing in the clean room. As described above, as an apparatus for performing the static electricity removing process and the cooling process for the disc-shaped injection-molded article in the clean room, those shown in FIGS. 3 and 4 have been conventionally known. That is, the conventional static electricity removing and cooling device for a disc-shaped injection-molded product shown in FIG. 3 includes an injection molding machine 1, a take-out means 2, and a processing stage 3, which are installed in a clean room. . The disc-shaped injection-molded product 5 molded by the injection molding machine 1 and held in the movable mold 4 is held by the take-out means 2 by the take-out robot when the movable mold 4 is opened.
The receiving position 6 of the transfer means 6 provided on the processing stage 3 is sequentially taken out by the A having the horizontal axis C.
It is conveyed by the swivel type conveyance mechanism 7 to A, and the axis C
Is received in the receiving position 6A in a state in which the direction of is reversed in the vertical direction and is transferred from here to the transferring position 6B, and during this transfer, static electricity removing processing is performed by a plurality of static electricity removing means 8 composed of ion generators, and After radiative cooling, it is stocked in the stocking means 9 formed by a pole stacker with the axis C oriented vertically.

Further, a conventional static electricity removing and cooling device for a disc-shaped injection-molded article shown in FIG.
It is equipped with an extraction means 2 and a processing stage 3, which are installed in a clean room. The disc-shaped injection-molded product 5 molded by the injection molding machine 1 and held in the movable mold 4 is horizontally moved by the gripping portion 2A of the take-out means 2 formed by the take-out robot when the movable mold 4 is opened. It is sequentially taken out with the axis C, and is transported by the transport mechanism 7 to the receiving position 6A of the transfer means 6 provided on the processing stage 3, and is placed at the receiving position 6A with the orientation of the axis C reversed in the vertical direction. In a state where the axis C is received and transferred from here to the delivery position 6B, static electricity removal processing is performed by a plurality of static electricity removal means 8 composed of ion generators during this transfer, and heat radiation and cooling are performed. , Is stocked in the stocking means 9 by a pole stacker.

However, in the conventional static electricity removing and cooling device for a disc-shaped injection-molded product, the axis C of the disc-shaped injection-molded product 5 is oriented vertically, that is, the disc-shaped injection-molded product 5 is laid sideways. The transfer means 6 transfers the transfer position 6A to the transfer position 6B. Therefore, there is a drawback that the static electricity removing effect and the cooling effect are poor.

The reason is as follows. That is,
In a clean room in which a static electricity removing and cooling device for a disc-shaped injection-molded product is installed, the flow direction of clean air is set to the downward direction, that is, a down blow system. Therefore, it is considered that the flow of ions emitted from the static electricity removing means 8 is also down blown. However, since the disk-shaped injection-molded product 5 is transferred by the transfer means 6 in a state where the axis C thereof is vertically oriented and is laid sideways, the upper surface of the disk-shaped injection-molded product 5 is effectively removed of static electricity, It cannot be expected to effectively remove static electricity from the bottom surface. Also, regarding heat radiation cooling of the disc-shaped injection-molded product 5 subject to the flow of clean air, the upper surface is effectively cooled, but the lower surface cannot be expected to be effectively cooled.

On the other hand, since the disc-shaped injection-molded article 5 is constructed so that the axis C of the disc-shaped injection-molded article 5 is oriented vertically and is laid sideways by the transfer means 6, the plane area of the transfer means 6 becomes large, and that much. The installation floor area of the processing stage 3 also increases. On the other hand, a clean room is significantly more expensive to construct than a normal upgraded building, so it is required to limit the building area as small as possible. But,
In the conventional static electricity removing and cooling device for a disk-shaped injection molded product, the floor area of the clean room is inevitably large because the floor area of the processing stage 3 is large. Therefore, the construction cost of the clean room is high.

[0007]

The problems to be solved are that the conventional apparatus is inferior in the static electricity removing effect and the cooling effect, and the construction cost of the clean room in which the apparatus is installed is high.
