Abstract
Abstract A device for sampling inspection consisting of means for continuously conveying products from a manufacturing machine such as a heading machine; means for repeatedly discharging products in groups; means for holding a sample which represents respective groups of products it belongs to; means for inspecting the sample to judge its quality and transmit an electrical signal corresponding to the results of the inspection; and a member for holding the products discharged from the conveyor means for a given period of time and adapted to further discharge or hold the products according to the electrical signal. By this signal, the operation of the manufacturing machine is halted when an inferior product is produced, thereby enabling the production of inferior products to be minimized. In addition, inferior products can be automatically separated from the satisfactory products already discharged.
