た。2. Description of the Related Art Instant noodles in a bag include a metal bag containing a powdered seasoning and a non-metallic bag containing a liquid seasoning. In some cases, since the bags are not visible, it is necessary to confirm the presence of each bag before shipment by another means such as machine detection. Japanese Patent Application Laid-Open No. Sho 60-195481 discloses a method and an apparatus used for the above detection.
According to this, a detection object a having a detection distance exceeding the thickness of the nonmetallic object and a detection end a The presence or absence of an object is determined by abutting a detection unit having a detection end b having no detection distance and continuously capturing detection signals (ON / OFF signals) of both detection ends. In the above prior art, the detection end a is based on the detection of a metal object exceeding the thickness of the nonmetal object. However, the detection distance of a current proximity switch or the like is as short as about 7 mm or less. If the thickness of the object exceeds or is equal to this, there is a problem that detection is impossible or malfunction occurs.

The distance to the bag 3 is continuously detected and measured as the thickness of the non-metal bag 4. Eddy current sensor 5
More specifically, when the detection is performed by using both the metal bag 3 and the non-metallic object 4 (good products)
Is a constant distance A to the metal bag 3 as the thickness of the non-metal bag 4 is detected for a certain period of time. On the other hand, when the nonmetallic bag 4 is not provided, only a certain distance B shorter than the detection distance A in the case of the non-defective product is detected, including the fact that the sensor 5 bounces due to the vibration during transfer. If neither of the bags 3 and 4 is present, no detection value is obtained (the above is a case of a defective product).

Alternatively, while the instant noodle 1 is in the detection unit 6, the detection distance B (or the distance B 'satisfying A'> B '> B) in the case of a defective product is detected as a certain frequency, and the product is determined to be defective. Others are considered non-defective. Alternatively, they can be performed together,
As described above, the quality can be reliably determined. still,

Is sent to the controller 8 together with the output signal of the sensor 5. The controller 8 logically determines the output signals of the eddy current sensor 5, the photoelectric switch 13 and the encoder 7. That is, the detection of a non-defective or defective product by the eddy current sensor 5 and the photoelectric switch 13 and the encoder 7
The logical determination is performed by superimposing the detection of time by In other words, while the photoelectric switch 13 detects that the instant noodle 1 is in the detection unit 6 and the encoder 7 performs pulse counting of a certain number, the sensor 5 continuously detects a non-defective product or detects a defective product at a certain frequency. Is detected, a good product or a defective product is determined.

する上記の検出装置。1. A metal object in a flexible outer container and a metal object on the metal object.
A detection device for detecting a flexible non-metallic object , comprising: (1) an abutting object to be detected from above, and detecting a distance to the metal object as a thickness of the non-metallic object; An eddy current sensor, (2) for forcing the non-metallic object to have a certain thickness between the sensor and the metallic object when the sensor contacts the object from above. A device, (3) an encoder that outputs a predetermined pulse signal in response to the movement of the object, (4) a controller that logically determines the signals output by the sensor and the encoder, and (5) a logical determination of the controller. And (6) a device for sequentially transferring the detected object from the detection position of the eddy current sensor to the excluded device. The above detector .

うことを特徴とする上記の検出方法。2. A metal object in a flexible outer container and over it.
A detection method for detecting a flexible non-metallic object , comprising: (1) transferring the detected object sequentially at a constant speed;
(2) An eddy current sensor for detecting the distance to the metallic object as the thickness of the non-metallic object from above is brought into contact with the object being transported, and (3) the sensor and the Forcing the non-metallic object to have a certain thickness between the metallic object and (4) and continuously capturing the detection signal of the sensor, and (a) the signal is transmitted to the metallic object and the non-metallic object. In the case of including both of the metal objects, if the non-metal object has a constant thickness for a predetermined period of time, a non-defective product is determined; otherwise, a defect is determined, or (b) the signal is not output. Or, when the signal does not include the non-metallic object, the distance to the metallic object is determined to be defective when a certain frequency is detected within a predetermined time, and otherwise, a non-defective product is determined. , (C), (a) and (b) are performed together. The detection method described above.
