Here, the outline of the algorithm by the inspection means 7 will be described. In the image processing, the image pickup device 6 picks up an image of the end portion of the guide portion 1, and from the grayscale image picked up by the image pickup device 6, FIG.
The edge image as shown in (3) is extracted, and whether the headed bar 3 is a good product or a defective product is determined based on the edge image. Here, the pixels of the edge image correspond to the addresses of the frame memory, and the difference between the two addresses is related as the length within the edge image. Further, the position of the image pickup device 6 is determined so that the vertical direction of the edge image is the moving direction of the headed rod 3 (that is, the direction parallel to the upper opening edge of the guide portion 1). Then, the first to fourth inspection regions including scan lines and windows are set in the vertical and horizontal directions at the predetermined positions of the edge image to obtain the total length of the headed bar 3 and the length of the head 2. Specifically, it is parallel to the moving direction of the headed rod 3 that moves the protruding pieces 13a and 14a and is slightly displaced to the head 2 side from the tip of the non-defective shaft 4 of the headed rod 3. Bar with head 3 in position

Indicates that there is no work, that is, there is no headed bar 3). Next, the second scanning area B is searched by following the first scanning area A, and the address of the tip of the shaft portion 4 of the headed rod 3 is obtained. Further, the third scanning area C is searched for the address of the upper end opening edge of the tip of the guide portion 1 (that is, the upper surface of the vibrating feeder 5). Further, the headed bar 3 is searched by searching the fourth scanning area D by following the search of the second scanning area B.
Find the address of head 2 of. Fig. 5 (a) is a bar with head 3
Is the address of the tip of the shaft portion 4, and B is the address of the head portion 2 of the headed rod 3. Then, the total length of the headed rod 3 is obtained by (address of head 2)-(address of tip of shaft 4) = (total length of rod 3 with head), and
The head length is calculated by (address of head 2)-(address of upper edge of tip of guide portion 1) = (length of head 2),
Based on this, it is determined whether the inspected head bar 3 is a good product or a defective product, and it is determined whether other types are mixed.

When passing, since the chute member 15 is tilted in the direction intersecting the conveying direction of the headed bar 3, the headed bar 3
Is sloping with respect to the transport direction, the shaft portion 4 hits the inner surface side of one plate member 14 and the head 2 is placed on the edge portion of the upper edge of the plate member 14, so it falls in the gap 18 portion. It will be transferred smoothly without doing. By the way, when the chute member 15 is tilted in the direction intersecting the conveying direction of the headed rod 3, the shaft portion 4 abuts against the inner surface of one of the plate materials 14 and moves so as to rotate on the inner surface of the plate material 14 due to vibration. By doing so, the headed rods 3 can be quickly moved by aligning them, and further,
In this case, by making the upper end edge on the inner surface side of one plate member 14 the edge portion 20, the lower surface of the head 2 is supported by the edge portion 20 by line contact, and this line contact portion is the head portion. 2 will be slidably transferred, and headed bar 3
Is faster.

(In this case, the imaging device 6
The shutter is opened 36 times a second to inspect up to 20 headed rods 3), and the inspection unit 7 performs image processing on the image captured by the image capturing device 6 to determine whether it is a good product or a defective product. , A signal is sent to the cylinder device 23 of the selecting means 8 on the basis of this determination result to control the cylinder device 23,
The headed bar material 3 supplied from the end of the vibrating feeder 5 is selected so that good products are supplied to the good product box 24 and defective products are supplied to the defective product box 25. A flowchart of the algorithm is shown in FIG. 6, and based on this processing procedure, the non-defective / defective product of the headed rod 3 transferred through the guide portion 1 by the vibration of the vibrating feeder 5 is determined and selected. .

速で行うことができるものである。According to the first aspect of the present invention, as described above, the upper end portion of the vibrating feeder having the slit-shaped guide portion inclined in the direction intersecting the conveying direction is provided in the guide portion. Since it is a device that conveys with the shaft of a headed rod having a head inserted in and the head of the rod with a head placed on the upper opening edge of the guide part, it is tilted in the direction intersecting the conveying direction. With the slit-shaped guide part, the rods with heads can be aligned and transferred at high speed, and moreover, an image pickup device for picking up images of the rods with heads conveyed by a vibration feeder and an image picked up by the image pickup device can be displayed. Inspecting means for processing and determining whether the headed bar material is good or defective, and a selection means for selecting good or defective headed bar material supplied from the vibration feeder based on the determination result of the inspection means. Is provided In, in which it is possible to perform good and judgment of defective headed rod for transferring at a high speed as described above, in the automatic high-speed sorting.
