Patent number: 7071426Abstract: In a combination weighing device, weight measurement devices are respectively connected to pool hoppers and weighing hoppers. When the results of a combination calculation indicate that a combination is not complete, a control unit determines whether or not a total value of a weight value from predetermined weighing hoppers and a weight value from pool hoppers that supply articles to the weight hoppers exceeds a predetermined value. Thus, an over-scale state in the weighing hoppers can be avoided by supplying additional articles stored in the pool hoppers to the weighing hoppers. The present invention provides a combination weighing device that is capable of improving operational efficiency.Type: GrantFiled: December 8, 2003Date of Patent: July 4, 2006Assignee: Ishida Co., Ltd.Inventors: Masaya Fujii, Takumi Kawamura
