Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply apparatus for automatically supplying components to an automatic assembling machine in an assembling process.

2. Description of the Related Art In recent years, as automation in an assembling process progresses and a production mode changes to a high-mix low-volume production, a stable component supply device capable of instantaneously switching component types and occupying an important position. Hereinafter, an example of a conventional component supply device will be described with reference to FIG.

In FIG. 4, 1 is a supply part, 2 is a parts feeder, and 3 is a chute adapted to the shape of the supply part 1.
In the component supply device configured as described below, the parts feeder 2 vibrates and aligns the supply components 1 on the chute 3 and sequentially supplies the supply components 1 to the tip of the chute 3.

Problems to be Solved by the Invention However, in the above-described configuration, since the shape of the chute is adapted to the shape of each supply component, the shape of the supply device changes when the component shape changes.
In addition, there is a problem in stability because the arrangement of parts relies on vibration. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a stable component supply apparatus capable of instantaneously switching the type of component.

Means for Solving the Problems In order to solve the above problems, a component supply device of the present invention includes a carrier reel for winding a carrier tape having holes for accommodating supply components in a line at a constant interval, and A cover reel for winding a cover tape removably superimposed on the carrier tape so as not to fall off, a supply reel for storing components and winding the carrier tape covered by the cover tape, and the carrier tape And an index roller for intermittently feeding the carrier reel, the cover reel,
The supply reel and the index roller are provided with one or a plurality of taping cassettes in which the carrier tape, the cover tape, and the carrier tape covered with the cover tape are rotatable in both a winding direction and an unwinding direction. It is a thing.

According to the present invention, the type of component can be instantaneously switched by replacing the taping cassette or automatically switching a plurality of taping cassettes by the above-described configuration.
In addition, stable supply is possible because the supply parts are placed on the carrier tape at regular intervals and supplied, and in the taping cassette, after the parts are supplied, the empty carrier is wound up. The tape and cover tape are unwound from the state of being wound by the rotation of the carrier reel, the cover reel, the supply reel, and the index roller in the opposite direction, and are unwound in the opposite direction. Since the tape and the supply reel are wound together again by the supply reel, it can be reused together with the carrier tape and the cover tape, and the parts can be supplied and stored simply by driving in the reverse direction. Can be performed.

Embodiments Hereinafter, a component supply apparatus according to an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIGS. As shown in FIG. 1, in the component supply apparatus of the embodiment, a plurality of taping cassettes 4 are installed on a cassette switching table 5 which can be moved in the direction of the arrow in the figure. As shown in FIG. 2, the taping cassette 4 has holes for accommodating supply parts 6 at regular intervals.
A carrier tape 7 having 7a is provided so as to be wound around the supply reel 11 with the supply component 6 housed in the hole 7a and covered with the cover tape 9 so that the supply component 6 does not fall off. I have. Reference numeral 8 denotes a carrier reel for winding the carrier tape 7, and reference numeral 10 denotes a cover reel for winding the cover tape 9. Reference numeral 12 denotes an index roller for intermittently feeding the carrier tape 7 at regular intervals. The supply reel 11, carrier reel 8, cover reel 10, and index roller 12 can be rotated in both the feeding and winding directions. As shown in FIG. 3, the carrier tape 7 and the cover tape 9 are removably overlapped with each other by fitting a groove 13 provided on the carrier tape 7 with a projection 14 provided on the cover tape 9.

The operation of the component supply device configured as described above will be described below. The carrier tape 7 wound around the supply reel 11 and containing the supply component 6 is intermittently fed at regular intervals by an index roller 12, and the cover tape 9 is wound around the cover reel 10 (second
(See FIG. (B)), supply component 6 on index roller 12
Are sequentially supplied.

A plurality of taping cassettes 4 configured as described above are set on the cassette switching table 5, and when the type of the component 6 is switched, the cassette switching table 5 is automatically switched. For the empty taping cassette 4,
An operation of storing the supply component 6 in the hole 7a of the carrier tape 7 exposed from the carrier reel 8 at a constant interval by the index roller 12, superimposing the cover tape 9 fed from the cover reel 10 and winding the supply tape 11 on the supply reel 11. Is performed by a taping device different from the component supply device.

Effect of the Invention As described above, the present invention realizes instantaneous switching of component types corresponding to high-mix low-volume production, and realizes stable component supply corresponding to complete automation. In the taping cassette, since the carrier tape and the cover tape are detachable, each tape can be reused, and each reel and index roller can rotate in both directions. In this state, it is possible to supply and store components only by driving in the reverse direction.
