Abstract

(57) [Abstract] [Purpose] To realize a screw supply carrier tape at a lower cost in a screw component assembly used for screw supply when tightening screws. [Structure] A plurality of holes 1 having a diameter smaller than that of a leg 5a of a screw 5 are formed in a long member 3 extending in one direction along the longitudinal direction, and a plurality of holes 1 are radially provided around the holes 1. Is a threaded component assembly in which the notch 4 is formed and the leg 5 a of the screw 5 is fitted into the hole 1.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw part assembly used for supplying screws when tightening screws.

[0002]

2. Description of the Related Art Regarding the supply of screws for automatic screw fastening work, as shown in, for example, Japanese Patent Laid-Open No. 63-176805, a screw component assembly in which a large number of screws are continuously held by a carrier tape is provided. There is a supply method using the above method, which will be described with reference to FIGS.

FIG. 3 is a perspective view of a carrier tape, and FIG.
(A), (b) is a perspective view and a side view of the carrier tape which provided the screw fall prevention cover in other prior art examples.

3 and 4, reference numeral 11 denotes a hole, and the hole 11 has a size larger than the diameter of the leg 9a of the screw 9 so that the screw 9 can be easily taken out. Also,
Reference numeral 12 is an adhesive, which adheres the head 9b so that the head 9b of the screw 9 does not fall off. Further, the screw drop prevention cover 13 is welded onto the carrier tape 8 and the screw 9 is similarly attached.
The head 9b of the head is prevented from falling off.

[0005]

However, in the above structure, an extra material such as an adhesive or a drop-off prevention cover is required to hold the screw on the carrier tape, which increases the cost of supplying the screw by the carrier tape. Was connected to.

The present invention solves the above conventional problems.

[0007]

In order to achieve this object, a screw component assembly according to the present invention comprises a long member extending in one direction and a hole having a diameter smaller than a leg portion of a screw along a longitudinal direction. A plurality of portions are formed, a plurality of cut portions are radially formed around the hole portion, and the leg portion of the screw is fitted into the hole portion.

[0008]

As described above, according to the present invention, when the screw is inserted and supported, the hole has a diameter smaller than that of the leg of the screw and the radial notch formed around the hole. Since the screw can be supported only by bending the long member (carrier tape) in the hole portion, the cost of the carrier tape can be suppressed because the adhesive and the fall prevention cover that have been conventionally required are unnecessary. The screw supply is realized at low cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A screw component assembly according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a screw component assembly according to an embodiment of the present invention, and FIG. 2 is a sectional view when a screw is supplied in the embodiment.

In the figure, reference numeral 1 is a hole portion for inserting and supporting a screw and having an inner diameter smaller than the diameter of the leg portion 5a of the screw 5. 2 is a transport hole for transporting the long member (carrier tape) 3, 4 is a notch formed radially around the hole 1, 6 is a screw on the carrier tape 3,
It is a push-up pin that pushes up the leg portion 5a of the screw supported on the carrier tape 3 from below.

According to the above structure, when the screw 5 is inserted and supported, the leg 5a of the screw 5 spreads the hole 1 due to the radial notch 4 provided around the hole 1. The bending of the carrier tape 3 supports the legs of the screw. Further, when supplying the screws, the screws supported on the carrier tape are pushed up from below by the push-up pins 6 to release the screws 5 from the holding on the carrier tape and pick and place with a screw tightening driver (not shown). It is also possible to supply by. Further, since the carrier tape is not broken at the time of supply, the carrier tape can be recycled even after the screw is supplied.

As described above, the carrier tape of this embodiment uses a resin material for recycling, but it can also be manufactured once by disposable and using paper.

[0014]

As described above, according to the present invention, the screw supply by the carrier tape can be realized at a low cost.
