Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a screw, a rivet,
An alignment transfer device that aligns and transfers pins or bolts and other rod-shaped parts with heads, and determines that the rod-shaped parts with heads that are transferred by this alignment and transfer device are good or defective products, and rejects defective products to transfer the good products to a specified position. The present invention relates to a sorting device for rod-shaped parts with a head.

2. Description of the Related Art Generally, when a head-shaped rod-shaped component such as a screw, a rivet, a pin or a bolt is transferred with its head on top and its legs hanging down, usually two parts are transferred as shown in FIG. The rails 111 are arranged in parallel, and a slight vibration is applied to the rails 111 from a vibration driving source so that the heads 1 are attached to the rails 111.
The head-equipped bar-shaped component 101 whose seating surface 04 is supported is forwarded, or the rail is supported by the head-bearing surface of the headed bar-shaped component by inclining the rail at a predetermined angle without vibrating. In this way, the rod-shaped parts are made to flow down and supplied. In addition, as another alignment transfer device, in order to support and transfer the head seat surface of the headed rod-shaped component, as in the case of the above, instead of the rail, a belt (not shown) is moved in parallel at predetermined intervals. There is also an arrangement in which the headed rod-shaped parts between these belts are forwardly moved by arranging them apart and circulating them at the same speed in the same direction. These aligning and transferring devices have been put into practical use according to their respective uses and are widely used as part aligning and transferring means, and are often used as means for aligning and transferring parts even in a sorting device for sorting parts into good products or defective products. Is the current situation.

[0003]

However, in the case where the head-equipped rod-shaped component is supplied by giving a slight vibration to the rail as described above, there is no problem as long as it is simply supplied to the front. In the supply of so-called washer-incorporating screws that combine parts and washers, this screw is inclined by the washer in any direction without hanging correctly, or overlaps with each other's screws. In particular, in the work of selecting good products and defective products by judging whether the leg length, screw diameter, etc. of the screw are the preset predetermined dimensions, the inclination of the screw varies and the screw itself also shakes during movement. Since it has occurred, it was not possible to make an accurate selection judgment. Also, when the inclined rail is used, the flow speed of the parts is not constant and all parts of the inclination itself are not constant and may be disturbed. However, there is still a lack of certainty in determining defective products. Furthermore,
The one in which two belts are synchronously circulated in the same direction to transfer the parts can transfer the headed rod-like parts relatively stably, but this is also used as the transfer part of the sorting device. In this case, there is a problem that the belt interferes with the determination work in the measurement by the camera or the sensor as the determination unit and the determination range is narrowed.

A first object of the present invention is to solve the above-mentioned problems and to obtain an alignment transfer device which has a simple structure and can be transferred with the legs always hanging down and with reduced noise. is there.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIG.
2 will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a screw as a head-shaped rod-shaped component, and this screw 1 has a leg 2 with a washer 3 assembled and held. These screws 1 extend in a substantially horizontal direction, and a head 11 is placed on a rail 11 of a vibrating component supply unit 10 which is arranged in parallel at a predetermined interval. The head seat surface is supported through the rail 11, and the rail 11 is slightly vibrated by a vibration drive source (not shown) so that the screw 1 is fed forward. A transfer member 21 is arranged close to the tip of the rail 11 and slightly above the same, and the transfer member 21 is arranged on the transfer member 21 along the rotation locus on the tip of the rail 11. Ring-shaped magnet 2 along the outer circumference
2 is embedded in the lower surface of the screw 1 to form the rotation unit 20, and the head 4 of the screw 1 is magnetically attracted to the lower surface of the transfer member 21 by magnetic force so that the screw 1 is aligned and transferred as shown in FIG. It has become. The transfer member 21 is fixed to an upright rotating shaft 22 which is rotated at a predetermined speed by a rotary drive source (not shown) arranged below the transfer member 21.
Is designed to rotate on a horizontal plane.

Around the transfer member 21, a determination camera 31 or a sensor for determining whether or not the determination factors such as the leg diameter, leg length, and thread shape of the screw 1 are preset values, and a built-in control. A determination unit 30 composed of a unit (not shown) is provided, and the determination camera 31 of the determination unit 30 detects the imaged light of the determination unit 30 on the transfer member 21.
Is placed so that the magnetically adsorbed screw 1 traverses the moving path of rotation. Further, next to the judgment camera 31, there is provided an excluding unit 40 for removing the screw 1 judged as a defective product by the judgment signal from now on.
A defective product discharge chute 41 is installed below the movement locus to guide the screw 1 removed by the excluding unit 40 to a predetermined position. This exclusion unit 4
0 is designed to remove the screw 1 which is determined to be defective by the lever 42 that horizontally swings according to the determination signal from the determination camera 31, but is not limited to this and is determined to be defective. Any configuration may be used as long as the screw 1 is removed.

Further, a non-defective product discharge chute 51 is arranged at the final end of the screw 1 which is set in front of the movement locus so as to collect the non-defective product screw 1 which is magnetically attracted and transferred to the transfer member 21. A regulating member 52 for moving the attracted screw 1 away from the magnet 23 by utilizing the rotation of the transfer member 21, that is, a regulating member 52 for moving the screw 1 in the outer peripheral direction of the transfer member 21 is provided on the upper part of the non-defective product discharge chute 51. It is installed. These non-defective product discharge chute 51 and regulation member 5
Reference numeral 2 constitutes a non-defective item recovery unit 50. Further, since the screw 1 is magnetized by the magnet 23 of the transfer member 21 to the non-defective product discharge chute 51, the magnetic remover 53 for removing this magnetic force is fixed.

In such a structure, when the screw 1 is supplied on the rail 11 of the vibrating component supply unit 10, the screw 1 is transferred from the tip of the rail 11 to the transfer member 21 which constitutes the rotation unit 20 of the alignment transfer means. Is magnetically attracted to the lower surface of the head with the head 4 up. This screw 1 is rail 11
When it is continuously and repeatedly supplied above, the transfer member 21
The head 4 is continuously adsorbed at predetermined intervals and is transferred in a predetermined direction by the rotation of the transfer member 21.

In this way, when the screw 1 reaches the image pickup position of the determination camera 31 as the determination unit 30 in the selection means, the determination camera 31 determines whether the screw 1 is a good product or a defective product, and the screw 1 is When it is determined that the product is defective, the determination signal is transmitted to the exclusion unit 40. This allows
The screw 1 determined to be a defective product is removed and falls on the defective product discharge chute 41. On the other hand, the screw 1 determined as a non-defective product is further transferred while the head 4 is magnetically attracted to the transfer member 21, and reaches the non-defective product discharge chute 51 of the non-defective product recovery unit 50 provided in a predetermined position in advance.

When this position is reached, the screw 1 moves in the outer peripheral direction of the transfer member 21 by the restricting member 52 and drops into the non-defective product discharge chute 51. Since the dropped screw 1 passes through the magnetic remover 53, the magnetism of the screw 1 magnetized when magnetically attracted to the transfer member 21 is removed, and the non-defective screw 1 is recovered. By repeating the above operation, a large number of good and defective screws 1 can be automatically selected accurately.

[0013]

As is apparent from the embodiments described above, the present invention allows the transfer member 21 having the ring-shaped magnet 23 embedded in the lower surface thereof to be rotatable on the horizontal plane along the outer periphery. The head 4 of the head-shaped rod-shaped component is magnetically attracted to the lower surface of the transfer member 21 and magnetically attracted, and the head-shaped rod-shaped component is aligned and transferred. Therefore, as in the prior art, screws, rivets and bolts are used. The headed rod-shaped parts, such as heads, do not tilt during the alignment transfer, and especially when the so-called washer built-in screw, which is a combination of the headed bar-shaped parts and the washer, transfers the upper surface of the head of the screw. Since it is only magnetically attracted to the member, this screw enables the leg portion to be accurately suspended without the leg portion being inclined by the washer.

Further, in the above structure, a judging unit 30 is provided in a direction traversing the movement locus of the headed rod-shaped parts which are magnetically attracted to the lower surface of the transfer member 21 and are aligned and transferred. Unit 40 for eliminating head-shaped rod-shaped parts determined to be defective by the signal of
And a non-defective item recovery unit 50 for retrieving the non-defective non-defective headed rod-shaped component is arranged at the final end of the movement path. In the work of selecting good products and defective products by determining whether the leg length, leg diameter, etc. of the rod-shaped parts are the predetermined dimensions, all the rod-shaped parts with heads are in a hanging state, so it is judged by the judgment unit whether they are good or bad. Is stable and accurate judgment work can be performed. In addition, since the moving speed of the parts can be adjusted arbitrarily and a constant speed can always be obtained, it is possible to continuously sort without disturbing the judgment work at all times.
Reliability is also improved. Further, in the pass / fail judgment of the portion of the rod-shaped part with a head, there is no obstacle such as a rail or belt that hinders the judgment work as in the conventional case, and a peculiar effect such as a wide judgment range can be obtained.
