Problems solved by technology

However, for example, the workpiece preheated in the preheating chamber is held at the carburizing temperature in the preheating chamber until the intermediate chamber and the carburizing chamber are emptied, and the treatment time varies in the carburizing process and subsequent processes. case, there is a high probability that the scheduled cycle time cannot be processed

Abstract

A workpiece processing system and method to process a workpiece in processing chambers in order, in which even if processing duration varies at any chamber, such a variation does not affect the processing of the workpiece in other chambers. Each chamber performs processing of a workpiece in a predetermined order; a conveyor that conveys a workpiece to a next chamber; and a control device controls at least a start time of predetermined processing at each processing chamber. The control device sets: predetermined representative processing at a first chamber as a reference processing step, start time of the reference processing step as control start time, necessary processing duration specific to each chamber, necessary conveyance duration required to convey a workpiece between the chambers, and controls starting of the representative processing at each chamber while considering the control start time as origination.

Description

technical field [0001] The invention relates to a processing system and method for workpieces. Background technique [0002] The processing method of the workpiece involves a wide range. For example, when the workpiece is carburized, the workpiece is moved sequentially in a plurality of processing chambers, and the workpiece is moved and rotated by an actuator (actuator) in each processing chamber. The air pressure changes from a vacuum atmosphere to a high-pressure atmosphere, etc., and various controls are performed. [0003] Workpieces are conveyed sequentially in a plurality of processing chambers in which the conveying order of workpieces has been determined in advance. The workpieces that have been processed in a certain processing chamber are conveyed to the next processing chamber by the conveying device, and the processing in the next processing chamber is carried out. In the state, the workpiece is processed into an intermediate product or a final product through ...
