WEIGHING APPARATUS

PURPOSE:To maintain a high accuracy in the measurement of the weight by transferring work onto a transfer belt as conveying pawls having work placed thereon pass over a weighing base. CONSTITUTION:Work W is conveyed as placed on a pawl plate 3a of a number of rake-shaped conveying pawls 3 mounted on a chain conveyor 2 at a fixed interval. On the other hand, a part of a transfer belt 14 comprising a plurality of belt bodies which are arranged along the width thereof at the position of crossing with the pawl plate 3a slides in contact with the comb-shaped top surface of a weighing base 5 rising from a weighing apparatus 4 so that a horizontal part of the transfer belt 14 moves at almost equal speed in the same direction as the conveyor 2 through a drive roller 15 and both guide rollers 16. Then, as the conveying pawls 3 pass over the weighing base 5, a detection value of the moving position of the conveyor 2 outputted from a position detector 19 is inputted and based thereon, the work W is transferred onto the transfer belt 14 and output of the weighing apparatus 4 is taken in as weighed value on the weighing base 5 to select the classified weight level for the weighed value. The work W is made to drop onto a chute 9 above a discharge chute 9 thus selected to discharge. Thus, the weight can be measured at a high accuracy.
