Abstract

PURPOSE:To accurately and efficiently supply sheet-like materials having different shapes, sizes and weights which are irregularly loaded by constant amounts to a subsequent process by positioning end faces, weighing the materials and cutting an insufficient weight of materials to be supplied to the subsequent process. CONSTITUTION:Sheet-like materials S which are irregularly loaded on a lifter 1 are positioned by a kicker 2 and a positioning cylinder 15 so that their take-out ends are aligned with one another. Then they are lifted by a picker 3 having a sucking disk, chuck by a gripper 5 and discharged at a position B by a carrying mechanism 4. They are weighed together with a receiver 6 by a load cell of a weighing part 7 by a predetermined ratio of a set weight, so that an average weight of one sheet is calculated. A number of sheet-like materials S corresponding to an insufficient weight are cut by weighing after the insufficient number of sheets have been supplied, and the cut sheets are supplied by a cut supporter 9, completing the weighing. While a shooter 26 is horizontal, the weighed sheet-like materials S are moved by a discharging conveyer 11, arranged by an arranging mechanism 10 and efficiently supplied to a subsequent process by a constant amount.

Conventionally, even if a sheet is manufactured uniformly, it is impossible to make a fractional fine adjustment in a manufacturing process that requires a constant weight, and the versatile range is significantly limited. It is impractical, and in the end, people have to rely on manual work, and this manual work requires a lot of labor and work time, resulting in a large labor cost, which is a problem, especially irregular thickness and size. ， Providing a fixed amount of sheets with different specific gravity doubles the complexity, and cutting the fraction for quantification and replenishing it without excess or deficiency is too difficult, and the operator's fatigue is also remarkable. There was a problem such as an increase. The present invention is intended to easily eliminate these conventional drawbacks, and even if sheets of different shapes, sizes, and weights are irregularly stacked, they can be supplied to the next step with high accuracy and high efficiency in a fixed amount. An object of the present invention is to provide a sheet-form material constant amount supply device capable of performing the same.
