A transportation device capable of smoothly transporting even an object having a sticky surface or the like and a weighing device including the same are provided. A transportation device is for transporting an object placed on a trough in a predetermined direction by reciprocating the trough by a parallel link mechanism, and a control unit controls the rotation driving of a rotatable motor such that the trough moves forward with respect to the transportation direction at a higher velocity than backward.

Transportation device and combinational weighing apparatus including the same

A combination weighing apparatus includes a dispersion unit, a plurality of weighing hoppers, and a combination unit. The dispersion unit circumferentially disperses articles that drop from above. The weighing hoppers are arranged generally circumferentially below the dispersion unit. The combination unit combines weight results obtained from each of the weighing hoppers. In addition, a state of a drop position of the articles in the dispersion unit changes during operation.

Combination weighing apparatus with dispersion unit for dispersing articles

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.

Combination weighing device with multi-layered hoppers having controllable supply function

The present invention provides a combination weighing apparatus that can rapidly supply articles to the weighing units side by rapidly supplying articles to a plurality of supply units. Combination weighing apparatus () is provided with a plurality of weigh hoppers (), a conveyor (), and a plurality of individual supply apparatuses (). The weigh hoppers () measure the weight of the articles. The conveyor () is arranged alone the plurality of weigh hoppers (), and conveys articles. An individual supply apparatus () is provided for each of the plurality of weigh hoppers (), and supplies articles conveyed by the conveyor () to the weigh hooper ().
