As means for aligning and transferring the screws, two parallel rollers formed to have equal outer diameters or two tapered rollers formed to be tapered are used. When they are inserted, they do not easily come apart from each other, and in particular, in the case of screws with washers, there are many cases where the screws are sent while being overlapped, and the screws are not aligned vertically one by one in a hanging state. Therefore, there is a problem that accurate dimensional inspection cannot be performed. For this reason, there is a disadvantage that the roller must be lengthened and the rotation of the roller must be changed to cope with the problem. In addition, in the tapered roller, the sliding speed of the screws decreases toward the tip, so that not only the overlapping of the screws is not loosened, but also the overlapping of the screws increases at the tip of the tapered roller. Since it is sent in a tilted posture, accurate inspection and counting cannot be performed, and there are problems such as sometimes being unable to transfer due to clogging of screws. The present invention has been devised for the purpose of solving these problems and eliminating the overlapping of screws, and ensuring and aligning and transferring the screws.

In the figure, reference numeral 1 denotes a straight-type parts feeder, which comprises a hopper 2 for sequentially discharging a large amount of stored screws, a supply chute 3 for sending parts forward, and a vibration source 4. Immediately below the front end of the supply chute 3 of the parts feeder 1, rear portions of two tapered rollers 5, 5 are arranged. Each of the tapered rollers 5 has a tapered shape in which one end is formed to have a smaller diameter than the other end, and the outer periphery is smoothly finished. The tapered rollers 5, 5 are combined such that the small diameter portion and the small diameter portion and the large diameter portion and the large diameter portion are adjacent to each other, and are arranged such that the parts feeder 1 side is the small diameter portion and the tip is the large diameter portion. is there. Also, the two tapered rollers 5, 5 are
The spacing of the screws is wider than the outer diameter of the legs and smaller than the outer diameter of the head, and is arranged at a gentle inclination. The two tapered rollers 5, 5 are connected to a motor (not shown) so that they rotate in opposite directions (the inner sides that approach each other rotate in the upward direction). An optical detector 6 is provided below the tip of the tapered rollers 5, 5, and is located at a position where screws that slide between the tapered rollers 5, 5 and fall from the tip pass. .

出器６によって正確に計数することができる。Next, the operation and operation of the embodiment will be described. When the operation of the counter is started, the vibration source 4 operates and the Taber rollers 5, 5 rotate. Screws 1 stored in hopper 2
0 is sequentially discharged from the hopper 2 to the supply chute 3, and the discharged screws 10 are sent forward on the supply chute 3 by the action of the vibration source 4, and are arbitrarily sent from the front end of the supply chute 3 to the rear of the tapered rollers 5, 5. Fall in posture. The dropped screws 10 sequentially move forward between the tapered rollers 5 and 5, which are inclined and rotated. During this movement, the upward rotation of the tapered rollers 5 and 5 loosens the overlap of the screws 10 and causes the legs to move. Hang it in the middle and arrange it in a hanging state. Since the two rollers 5 and 5 are tapered rollers having a large diameter at the front end, the outer peripheral speed of the rollers 5 and 5 is increased toward the front end, the contact resistance with the screws 10 is reduced, and the sliding of the screws 10 is performed. The speed gradually increases. Therefore, as shown in FIG. 2, the distance between the screws 10 becomes larger toward the front. As a result, at the tips of the tapered rollers 5, 5, the screws 10 are appropriately spaced from each other and fall off one by one. The falling screws 10 can be accurately counted by the detector 6.

It is an optimal feeder for equipment and assembly equipment. Although a straight-type component feeder is used for the parts feeder, another type (such as a ball feeder) may be used.

効果が得られる。As is clear from the above embodiments, the present apparatus has two rollers rotating in opposite directions at a predetermined interval in front of the parts feeder, and the rollers are respectively positioned on the parts feeder side. Two tapered rollers having a small diameter and a large diameter on the other side are combined and arranged with a gentle inclination. According to this invention, the screws that fall from the supply chute are loosened by the action of the taper roller that rotates while being inclined, and the screws are aligned quickly in a hanging state. The distance between screws increases. Thus, at the tip of the tapered roller, there is a unique effect that the distance between the screws is appropriately set so that the screws can be reliably separated and supplied or dropped one by one. Therefore, the counting accuracy of the counter is significantly improved, and when supplying it to an inspection device, the posture of the screws can be stabilized and accurate inspection can be performed, and the clogging of the screws can be eliminated and the work efficiency can be improved. can get.
