  In FIG. 1, a resin-molded strip-like workpiece 1 is fed by a feed portion 2 by clamp feed to a length corresponding to a non-defective portion 16 for each pitch strip-like workpiece, and a strip-like workpiece 1 such as a recognition camera or a sensor. The defect detection unit 3 having a function of detecting the abnormality and processing the data by taking it into the program makes a pass / fail determination of the work product 1 for each pitch band. In the apparatus shown in FIG. 2, the recognition camera 7 that is most effective for discriminating molding defects of the resin-molded strip-like workpiece 1 is used. Thereafter, the strip-shaped workpiece 1 is sent to the cutting portion 4, and after the feeding portion 2 sends the strip-shaped workpiece 1 until it forms the strip-shaped workpiece 5 after being cut, it is cut by the cutting portion 4, and the good and defective products are separated and collected. Collected in part 6. In the apparatus shown in FIG. 2, a dedicated cutting die 8 shown in FIG. 4 is used for accurate cutting. The belt-like workpiece 1 is simulated on the program as shown in FIG. 3 based on the data taken in by the recognition camera 7 and determines the timing for cutting with the cutting die 8. The one-stroke defective strip portion 17 of the strip-shaped workpiece that has been determined to be defective by the recognition camera 7 and the one-stroke non-defective portion 16 that cannot form the non-defective product state 15 after cutting are as long as one stroke of the feed portion 2. Then, the product is cut by the cutting die 8 and is collected as a defective cut product 9 in the defective product collection BOX 10 from the defective product discharge groove 13 provided in the cutting die 8. Only a strip-like workpiece 1 stroke good product portion 16 capable of forming a good product state 15 after cutting is cut by a cutting die 8 as a good product cut product 11, transported by a conveyor, and stored in a collection magazine. 12 constitutes a method and apparatus for cutting the material to be collected at 12.

  According to such a configuration, the quality of the strip-shaped workpiece 1 is determined by the recognition camera 7 and the determination result is captured as data, thereby determining the quality of the workpiece after cutting, and the non-defective product state 15 cannot be formed after cutting. With regard to, by changing the timing of cutting with the cutting die 8 to continuous cutting, the defective product 9 is collected by the defective product collection box 10 separately installed, so that only the non-defective product 11 is collected. It can be recovered by the apparatus 12, the material loss of the strip-like workpiece 1 can be minimized, and the separation recovery loss of non-defective products after product recovery after cutting can be eliminated.

  In the present embodiment, the strip-shaped workpiece 1 is not limited to resin molding, but may be a strip-shaped material in which a continuous shape is formed while feeding the material at regular intervals, such as stamping and etching.
