      BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a miss detection system using a blow-

The present invention relates to a work miss detection system using an extraction sensor, and more particularly, to a work miss detection system using an extraction sensor, and more particularly, And more particularly, to a job missing detection system using a takeout detection apparatus that can efficiently detect a job omission through a device and a control system associated therewith.

      In general, in various industrial fields including automobile and machine tool manufacturing, various types of workpieces are directly coupled to the main body of the apparatus or are realized as a specific product through a combination of various workpieces.

      At this time, a method using a fastening member such as a bolt, a nut, a screw, or the like is most widely used to directly couple a specific workpiece to the apparatus main body or to bond workpieces to each other.

      Further, in order to use various fastening members for engaging the workpieces as described above, it is necessary to perform a welding operation for firmly fixing the nut for fastening to a certain point to the workpiece, a punching operation for drilling holes for bolt and screw fastening Is selectively performed.

      In one embodiment, at least one or more welding or punching operations are performed on certain workpieces through known welding apparatuses and various industrial punching apparatuses (not shown) as shown in FIG.

      On the other hand, as described above, when a welding or perforating work is arbitrarily omitted in manufacturing a product by performing at least one welding or punching work on a specific workpiece, the defective product is mass-produced.

      Conventionally, in order to prevent the omission of the welding or punching work as described above, a number corresponding to the work performed on each product in a predetermined number of product units is input to the controller, And the like.

      For example, three welds or perforations are performed on a workpiece, and when the workpiece is produced and packaged in 30 units, the number is entered in the controller as 90 (3 (number of operations) X 30 (number of products)) , The countdown is performed one by one when one operation is performed, so that it is possible to confirm whether or not the operation is missed according to whether or not the controller number reaches "0" when the work of 30 products is completed.

      However, in the case of detecting a job omission through the conventional method as described above, it is necessary to check whether a job is missing in a certain number of units. Therefore, as in the above example, It is necessary to check a large number of products and check for missing work. Therefore, there is a problem that the efficiency of job drop detection is remarkably lowered, resulting in a decrease in productivity and a waste of labor power unnecessarily.
