Patent number: 11926480Abstract: A container supplying apparatus includes a supply conveyer conveying containers and a screw engaging with the containers on the supply conveyer and conveying the containers to a downstream side. The screw is divided into an upstream screw and a downstream screw rotationally driven by different servomotors. In a case where no container is supplied to a specific bottle table of a weighing and filling apparatus, the upstream screw is decelerated and is then accelerated relative to the downstream screw. As a result, an interval of the successive containers is expanded, and a large interval is maintained therebetween. This supplies no container to the specific bottle table of the weighing and filling apparatus.Type: GrantFiled: September 26, 2022Date of Patent: March 12, 2024Assignee: SHIBUYA CORPORATIONInventors: Shun Okuhata, Masaharu Kawahara, Koji Kaya
