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

[0002]

2. Description of the Related Art A disk-shaped injection molded product of this type is molded by an injection molding machine installed in a clean room, and then subjected to a static elimination process and a cooling process in the clean room. As described above, the apparatus shown in FIGS. 3 and 4 is conventionally known as an apparatus for performing a static electricity removing process and a cooling process for a disk-shaped injection molded product in a clean room. That is, the conventional apparatus for removing and cooling static electricity from a disk-shaped injection molded product shown in FIG. 3 includes an injection molding machine 1, an extraction means 2, and a processing stage 3, which are installed in a clean room. . The disk-shaped injection-molded product 5 formed by the injection molding machine 1 and held by the movable mold 4 is provided with a gripping portion 2 of an extraction means 2 formed by an extraction robot when the movable mold 4 is opened.
A has a horizontal axis C and is sequentially taken out, and the receiving position 6 of the transfer means 6 provided on the processing stage 3
A is transported by the revolving transport mechanism 7 to the
Is received at the receiving position 6A in a state in which the direction of the direction is inverted in the vertical direction, and is transferred from the receiving position 6A to the transfer position 6B.

[0003] A conventional apparatus for removing and cooling static electricity from a disk-shaped injection-molded article shown in FIG.
It has an extraction means 2 and a processing stage 3, which are installed in a clean room. The disk-shaped injection-molded product 5 molded by the injection molding machine 1 and held by the movable mold 4 is moved in the horizontal direction by the gripping portion 2A of the ejection means 2 formed by an ejection robot when the movable mold 4 is opened. It is sequentially taken out with the axis C, transported by the transport mechanism 7 to the receiving position 6A of the transfer means 6 provided on the processing stage 3, and placed at the receiving position 6A with the direction of the axis C reversed in the vertical direction. It is transferred from here to the delivery position 6B, and during this transfer, the static electricity is removed by the plurality of static electricity removing means 8 constituted by an ion generator. After the heat is cooled, the axis C is directed vertically. , And stocked in a stock means 9 composed of a pole stacker.

However, in the conventional apparatus for removing and cooling static electricity from a disk-shaped injection-molded article, a state in which the axis C of the disk-shaped injection-molded article 5 is vertically oriented, that is, a state in which the disk-shaped injection-molded article 5 is oriented horizontally. The transfer means 6 is configured to transfer from the receiving position 6A to the transfer position 6B. Therefore, there is a disadvantage that the static electricity removing effect and the cooling effect are inferior.

[0005] The reason is as follows. That is,
In a clean room in which a device for removing static electricity from a disk-shaped injection-molded product and a cooling device are installed, the flow direction of the clean air is set to a downward direction, that is, a down-blow method. Therefore, it is considered that the flow of ions radiated 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 its axis C is vertically oriented and turned sideways, the upper surface of the disk-shaped injection-molded product 5 is effectively electrostatically removed. It is not possible to expect effective static electricity removal of the lower surface. Also, in the radiation cooling of the disk-shaped injection molded product 5 which is entrusted 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 disk-shaped injection-molded article 5 is configured to be transferred by the transfer means 6 in a state in which the axis C of the disk-shaped injection-molded article 5 is oriented vertically and horizontally, the plane area of the transfer means 6 becomes large, and The installation floor area of the processing stage 3 also increases. On the other hand, a clean room is much more expensive to construct than a normal upgrade building, so it is necessary to limit the construction area as small as possible. But,
In the conventional apparatus for removing and cooling static electricity from a disk-shaped injection-molded product, the floor area for installing the processing stage 3 is large, so that the floor area of the clean room must be large. Therefore, there is also a problem that the construction cost of the clean room is increased.

[0007]

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

[0008]

According to the present invention, there is provided a take-out means for taking out a disk-shaped injection molded product formed by an injection molding machine and held by a movable mold from the movable mold when the mold is opened;
Transfer means for receiving the disk-shaped injection molded product gripped by the gripping portion of the take-out means at the receiving position and transferring it to the delivery position; disposed in correspondence with the disk-shaped injection molded product transferred from the receiving position to the delivery position; And a stock stage for directly or indirectly receiving the disk-shaped injection molded article transferred to the delivery position by the transfer means. In the apparatus for removing and cooling static electricity of a disk-shaped injection molded product, the axis of the disk-shaped injection molded product is oriented sideways so that the disk-shaped injection molded product is transferred from a receiving position to a transfer position by the transfer means. In addition to improving the static electricity removing effect and the cooling effect, To achieve the purpose of reducing the construction cost of the installation is the clean room.

[0009]

According to the present invention, the state in which the axis of the disk-shaped injection-molded article is oriented in the horizontal direction, that is, the disk-shaped injection-molded article is moved vertically from the receiving position to the delivery position by the transfer means, so that static electricity is removed. The flow of ions radiated from the means acts equally on the front and back surfaces of the disk-shaped injection molded product, and the flow of clean air acts evenly on both front and back surfaces of the disk-shaped injection molded product, while reducing the plane area of the transfer means. As a result, the installation floor area of the processing stage can be reduced.
