    • It is an object of the present invention to provide a conveyor which estimates weight of a transport object while it is carried without using devices such as a load cell which directly measures weight.The conveyor has a plurality of zones forming a series of carriage ways. An approach-run zone and a weight-measurement zone are arranged adjacently in the conveying direction and are provided with different drive motors. The drive motor of the approach-run zone and the drive motor of the weight-measurement zone are controlled with respectively different predetermined rotation speeds as their target rotation speeds. A rotation speed sensing means obtains the change of rotation speed of the drive motor in the weight-measurement zone when a transport object is conveyed into the weight-measurement zone from the approach-run zone, and a weight sensing means then calculates the weight of the transport object based on the change of the rotation speed.
    • 本发明的目的是提供一种输送机,其估计运输对象在承载时的重量,而不使用直接测量重量的诸如称重传感器的装置。 输送机具有形成一系列支架路的多个区域。 接近运行区域和重量测量区域在传送方向上相邻布置并且设置有不同的驱动马达。 接近运行区域的驱动马达和重量测量区域的驱动马达以相应的预定旋转速度作为目标转速进行控制。 旋转速度检测装置在运送物体从进场区域输入重量测量区域时获得重量测量区域中的驱动马达的转速的变化,然后权重检测装置计算重量测量区域的重量 运输对象基于转速的变化。
