Abstract
In order to achieve reduction of a space occupied in a plant for manufacturing pharmaceutical tablets or the like, there is provided a compression molding machine that includes a table, an upper punch and a lower punch, a molded product collection mechanism, a molded product reservoir, and a housing for accommodating a connection end of an air convey path connected to the molded product reservoir. In this configuration, there is no need to additionally provide a dust removing device or a lifter outside the machine.
Claims14
A compression molding machine, comprising:
- a table comprising at least one die hole penetrating in a vertical direction;
- paired upper and lower punches each comprising a tip for sliding in the die hole to compress and mold a powdery material filled in the die hole;
- a molded product collection mechanism for collecting a molded product extracted from the die hole in the table;
- a molded product reservoir for temporarily reserving the molded product collected by the molded product collection mechanism;
- a convey path connected to the molded product reservoir so as to allow the molded product temporarily being reserved to be conveyed therealong;
- a housing for accommodating the table, the upper punch, the lower punch, the molded product collection mechanism, the molded product reservoir, and a connection end of the convey path, the connection end being connected to the molded product reservoir, wherein the convey path extends with an inclined angle above a lower surface of the molded product reservoir;
- and
- a gas supply device for supplying air into the convey path to carry the molded product along an inner peripheral surface of the convey path,
- wherein the gas supply device is connected to the connection end of the convey path for blowing the air into the convey path in a direction along the inner peripheral surface of the convey path,
- wherein the convey path is configured to allow the air and the molded product to be sucked from the molded product reservoir into the convey path, and
- wherein the air and the molded product are sucked spirally in a whirl along the inner peripheral surface of the convey path to flow away from the connection end.
