JPH0213547A - Feeding device for part - Google Patents

Abstract

PURPOSE:To instantaneously perform the change over of the kind of a part and to obtain a stabilized part feeding device by providing an index roller intermittently feeding a carrier tape at fixed intervals. CONSTITUTION:A feeding part 6 is fed in order on an index roller 12. A taping cassette 4 is set plurally on a cassette change over table 5, which is automatically changed over at the change over time of the kind of the part 6. On the taping cassette 4 became empty the feeding part 6 is stored into the hole 7a of a carrier tape 7 delivered from a carrier roll 8 at fixed intervals by the index roller 12 and the winding work on a feeding reel 11 by superposing the cover tape 9 delivered from a cover reel 10 is performed by the taping device which is separate from a part feeding device.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a parts supply device that automatically supplies parts to an automatic assembly machine during an assembly process.

BACKGROUND OF THE INVENTION In recent years, as assembly processes have become more automated and production patterns have changed to high-mix, low-volume production, stable parts supply devices that can instantly change the type of parts have become important. An example of a conventional parts supply device will be described below with reference to FIG.

In FIG. 4, 1 is a supply part, 2 is a parts feeder, and 3 is a chute that matches the shape of the supply part 1. In the parts supply device configured as follows, the parts feeder 2 vibrates and aligns the parts 1 to be supplied on the chute 3,
Problems to be Solved by the Invention for Sequentially Feeding the Parts 1 to the Tip of the Chute 3 However, in the configuration described above, the shape of the chute is matched to the shape of each part to be supplied, so the part shape is 7, the shape of the supply device changes. There are also problems with stability because it relies on vibration to align parts. SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a stable parts supply device that can instantly change the type of parts.

Means for Solving the Problems In order to solve the above problems, the parts supply device of the present invention has the following features:
A carrier reel for winding a carrier tape having holes arranged in a row at regular intervals for storing supplied parts, and a horn bar reel for winding a horn bar tape that is removably superimposed on the key rear tape so that the supplied parts do not fall out of the holes. The taping cassette has one or more taping cassettes each having a supply reel for storing parts and winding a carrier tape covered with horn bar tape, and an index roller for intermittently feeding the carrier tape at regular intervals.

Function: With the above-described configuration, the present invention can instantly change the type of parts by exchanging the taping cassette or automatically switching between a plurality of taping force sets I.

Furthermore, since the parts to be supplied are placed on the carrier tape at regular intervals, stable supply is possible.

EXAMPLE Hereinafter, a parts supply apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. As shown in FIG. 1, the component supply device of the embodiment has a plurality of taping cassettes 4 installed on a cassette switching table 5 that is movable in the direction of the arrow in the figure. As shown in FIG. 2, in this taping horn set 4, a carrier tape 7 having holes 7a for storing supply parts 6 at regular intervals stores the supply parts 6 in the holes 7a and replaces the old horn bar tape 9. , the supply reel 1 is held in a closed state so that the supply part 6 does not fall off.
1 is a carrier reel for winding the carrier tape 7, 10 is a horn bar reel for winding the horn bar tape 9, and 12 is an index for feeding the carrier tape 7 intermittently at regular intervals. These supply reel 11, carrier reel 8
, cover reel 10, index 1]-ra]2 are rotatable in both the feeding and winding directions. gear rear tape 7
As shown in FIG. 3, the cover tape 9 and the cover tape 9 are removably superimposed on each other by fitting the protrusions 14 formed by the carrier.

The operation of the component supply device configured as described above will be described below. The A-yaria tape 7 wound around the supply reel 11 and containing the supply parts 6 is intermittently fed by the index roller 12 at regular intervals, and the horn bar tape 9 is supplied with the horn part parts 6 one after another. .

A plurality of taping horn sets 4 configured as described above are placed on the cassette switching table 5, and the parts 6
When switching the type, pull 5 during the horn set switching day is automatically switched. When the empty taping cassette 4 is used, the supply parts 6 are stored in the holes 7a of the carrier tape 7 which is fed out from the carrier reel 8 at regular intervals by the index roller 12, and the horn bar tape is fed out from the horn bar reel 10. A taping device separate from the component supply device performs the work of overlapping the parts 9 and winding them onto the supply reel 1].

Effects of the Invention As described above, the present invention realizes instantaneous switching of parts types that supports high-mix, low-volume production, and also realizes stable parts supply that supports complete automation. In addition, since the key rear tape and cover tape are removable,
A major feature is that the tape can be reused.
