Description

Description: TECHNICAL FIELD The present invention relates to a screw supply for performing screw tightening,
In particular, it relates to a component assembly.

2. Description of the Related Art As products have become lighter, thinner and shorter, screws for fastening these products have also become smaller and smaller. As a method of supplying screws, generally, (1) a hopper having a rake plate to be separated and aligned;
A method consisting of an inclined chute that aligns and stocks the screws coming out of the hopper.

(2) a rotating or vibrating hopper for separating and aligning;
A method comprising a straight feeder and an escape for aligning and stocking screws coming out of a hopper.

Etc.

Hereinafter, an example of a method including the hopper having the scraping plate of the above-described conventional example (1) and the inclined chute will be described with reference to the drawings.

FIG. 5 and FIG. 6 are diagrams showing the outline of the screw supply section.
Reference numeral 1 denotes a rake plate that swings about the fulcrum pin 3 using the motor 2 as a drive source. Reference numeral 4 denotes a hopper for storing screws. Reference numeral 5 denotes a gate for allowing the screw scraped by the rake plate 1 to pass only in a correct direction, and for others to scrape the screw into the hopper. Reference numeral 7 denotes a chute which feeds and aligns a screw in a correct direction to the tip. Reference numeral 6 denotes an upper guide for preventing the screw from coming off upward.

The operation of the screw supply unit configured as described above will be described below.

First, the rake plate 1 swings around the fulcrum pin in the hopper 4 using the motor 2 as a drive source. The rake plate 1 has a groove in the upper part. When the rake plate 1 swings, the screw is scooped up, and the legs of the screw enter the groove and pass through the gate 5 in a state where the posture is stable, and the chutes 7 and Upper guide 6
Are aligned. When the scooping plate 1 is picked up, the screws which do not fit into the groove will flow on the scooping plate 1 but will be scraped into the hopper 4 by the gate 5 and not to the chute 7 Has become.

Problems to be Solved by the Invention However, in the screw supply unit having the above configuration,
If the screw has a shorter leg length than the screw diameter, the center of gravity is on the screw head side, so the screw leg does not enter the concave groove of the rake plate 1 and is not aligned on the chute 7. Also, screws with small leg diameters are difficult to enter into the concave grooves of the rake plate 1. Alternatively, it is difficult to adjust the clearance of the transfer portion to the chute 7, so that alignment is difficult. There was a problem that.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a stable supply of screws by adopting a taping structure in which screws are built in recesses.

Means for Solving the Problems To explain the above problems, the component assembly of the present invention is:
A component assembly that has a screw with a head and a leg in a plurality of long parts, and has a recess that is large enough to accommodate the head of the screw and to regulate the position of the head. And a part formed in the recess so that the leg of the screw can protrude, the hole being provided at the bottom of the recess and having a bent part around the circumference so that the leg of the screw is not caught. It is an aggregate.

Action The present invention provides a taping structure in which a screw head is built in a recess and a leg is arranged in a hole of the recess by using the above-described configuration to change the conventional alignment with the balance of the screw to a screw head. It is possible to supply a stable supply even if the balance is poor or precision machine screws.

Embodiment Hereinafter, a taping structure according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a taping structure according to a first embodiment of the present invention, and FIG. 2 is a side view showing a cross section.

In FIG. 1, reference numeral 8 denotes a concave portion for housing the head of the screw, a long portion having a hole at the bottom of the concave portion, and a pitch hole 9 for feeding the long portion 8 at a pitch. It is a taping body. 10 is a screw.

Reference numeral 11 denotes a bent portion provided with a hole at the bottom of the concave portion provided in the long portion 8 in the circumferential direction. The operation of the taping structure configured as described above will be described. As shown in FIG. 2, the head of the screw 10 is positioned in the concave portion, and the leg portion of the screw 10 is made to protrude from the hole at the bottom of the concave portion so as to cope with a change in length. In this state, suction is performed with a suction pipe (not shown) or the like to perform removal. At this time, since the bent portion 11 is rounded, the screw 10 or the like cut at the leg of the screw 10 is not caught and the screw 10 can be completely removed.

As described above, according to the present embodiment, the head of the screw is built in the recess, the hole is formed in the bottom of the recess, and a bent portion is provided in the circumferential direction of the hole, and the leg of the screw is provided in the hole. By arranging,
It is possible to stabilize the supply and take-out of a screw having a shorter leg length than a screw leg diameter or a screw having a small leg diameter (precision small screw).

Next, another embodiment of the present invention will be described. Fig. 3,
FIG. 4 shows another embodiment. First, FIG. 3 shows a taping 12 having a plurality of rows of screws, which can increase the stock of screws. FIG. 4 shows the upper tape 13 welded to the upper surfaces of the tapings 8 and 12, so that the screws can be prevented from jumping out.

Effect of the Invention As described above, according to the present invention, a screw can be supplied and taken out to a stable predetermined position. Particularly, it is effective for supplying a screw having a short leg length or a screw having a small leg diameter as compared with the diameter of the leg portion of the screw.
