It can be pushed up to the height. At this time, the electronic component a does not leave the guide blade 13 and the lead wire c adheres to the adhesive tape d while being centered by the blade 13, so that the electronic component a is not displaced in taping.

Further, since the lead wire retainer 26 guides the lead wire c from the upper side, the lead wire c is guided by the guide surface 14 of the guide blade 13.
The lead wire c does not incline, and the lead wire c can be reliably attached to the adhesive tape d without tilting.

[Embodiment] Next, an embodiment of the present invention will be specifically described with reference to FIGS. 1 to 9.

As shown in FIG. 1 to FIG. 5, a pair of conveyors 11 in which grooves 12 are formed at regular intervals are arranged in parallel, and this is constant in the direction shown by the arrow in FIG. 3 to FIG. Proceed at speed. By fitting the lead wire c into the groove 12, the electronic component a is formed so as to straddle the two conveyors 11.
Is mounted and is transported as the conveyor advances.

A pair of transport wheels 15 in which grooves 16 are formed at regular intervals are arranged on both sides of the conveyor 11, and the transport wheels 15 on both sides have the same rotating shaft 19 (or another shaft having a common central axis). ) Around at a constant angular velocity. The outermost peripheral portion of the transport wheel 15, that is, the groove 16
The tip of the protruding portion between the two passes through the uppermost portion of the conveyor 11, that is, a position lower than the top of the protruding portion between the grooves 12.

A drum wheel 17 having a common rotation shaft 19 is provided outside each of the transport wheels 15, and rotates with the transport wheels 15. The diameter of the drum wheel 17 is slightly larger than the bottom diameter of the groove 16 of the transport wheel 15, and an adhesive tape d is attached to the peripheral surface of the drum wheel 17 with the adhesive surface facing outward.

Between the conveyors 11, a pair of guide blades 13 for centering the electronic component a conveyed on the conveyors 11.
Are arranged. As shown in FIGS. 6 and 7, the guide blades 13 are arranged symmetrically and oscillate symmetrically in conjunction with each other.

For example, the guide blade 13 shown in FIG. 6 is an arm-shaped blade whose tip side is bent inward so that the interval between the guide blades is gradually narrowed, and its base end side is swingably attached to the frame 21. . Both guide blades 1
A pull spring 23 is hung near the base end of 3, and
In order to constrain the movements of each other symmetrically, gears 25 of the same shape fixed to the support shaft 22 at the base end mesh with each other. In addition,
A stopper 24 is applied to the inside of one of the guide blades 13 to regulate the shortest distance between the tips of the two guide blades 13.

As shown in FIGS. 1 and 3 to 5, the guide surface 14 of the guide blade 13 on which the lead wire c of the electronic component a is placed.
Is set so that its tip is the highest,
The tip portion reaches a height close to the adhesive tape d attached to the peripheral surface of the drum wheel 17 with a gap substantially the same as the diameter of the lead wire c. A plate-shaped lead wire retainer 26 is arranged on the guide blade 13 with a space slightly wider than the diameter of the lead wire c from the guide surface 14. Further, a leaf spring-shaped component retainer 30 is provided in the middle of the guide blade 13, and this elastically presses the central portion of the component body b from above. By these, the lead wire c is prevented from rising from the guide surface 14, and the lead wire c is fed while being almost in contact with the guide surface 14.

As shown in FIGS. 3 to 5, in the electronic component a, the lead wire c of the electronic component a extends from the groove 12 of the conveyor 11 to the transport wheel 15
While being successively fitted into the groove 16 of the guide blade 13, it is pushed forward on the guide surface 14 of the guide blade 13 by the conveyor 11 and the conveying wheel 15. As the electronic component a moves toward the tip side of the guide blade 13, the electronic component a rises according to the gradient of the guide surface 14, reaches the adhesive tape d attached to the drum wheel 17, and adheres to the surface thereof. In the meantime, as shown in FIG.
It is sandwiched between 3 and is centered at the intermediate position of the drum wheel 17 before reaching the tip of the guide blade 13.

Therefore, the electronic component a is attached to the adhesive tape d in a state where the component body b is just in the middle of the adhesive tape d, and the transport wheel 15 and the drum wheel 17 are rotated as they are to move the third component.
It is conveyed in the direction shown by the arrow in FIGS.

In the illustrated embodiment, when the lead wire c of the electronic component a is adhered to the adhesive tape d on the peripheral surface of the transport wheel 15, the presser 27 is used auxiliary. The pusher 27 is provided with the guide blade 13 as the transport wheel 15 rotates.
The lead wire c of the electronic component a extruded from the tip of is pressed against the peripheral surface side of the drum wheel 17 and adhered to the adhesive tape d. In FIGS. 1 to 5, a roller-shaped member is used as the pressing element 27.

8 (a) to 8 (c) show various mechanisms of the pusher 27, and FIG. 1 (a) shows a combination of an L-shaped link 30 and a spring 31 and a roller-like pusher 27 for a lead wire. c is pressed against the adhesive tape d. Further, in (b), a mechanism in which the rod 32 and the spring 21 are combined is used.
On the other hand, in (c), only the leaf spring 33 is used, and the lead wire c is pressed against the adhesive tape d at its tip.

FIG. 7 shows another embodiment of the guide blade 13. As shown in FIG. 6B, a spring 23 is applied to a gear 25 that rotates around a support shaft 22 that is a fulcrum of the guide blade 13, and the elastic force of the spring 23 is reduced in the direction in which the distance between the tips of the guide blade 13 decreases. While acting, both guide blades 13 move symmetrically. Further, in this embodiment, the cam 29
Thus, the guide blade 13 is rocked.

An adhesive roller 18 is arranged so as to be substantially in contact with the drum wheel 17, and another set of adhesive tape d wound around the roller 18 and supplied is pressed against the adhesive tape d attached to the peripheral surface of the drum wheel 17. As a result, two adhesive tapes d are attached to each other, and both ends of the lead wire c are fixed between them. The fixed interval of the electronic component a depends on the interval of the groove 16 of the transport wheel 15,
It goes without saying that it is constant.

[Advantages of the Invention] As described above, according to this invention, the lead wire c is adhesively fixed to the adhesive tape d attached to the drum wheel 17 immediately after the electronic component a is centered by the guide blade 13. The electronic component a is not displaced, and the electronic component a can be reliably taped in the middle of the adhesive tape d. Further, since the lead wire c is pressed so as not to float from the guide blade 13, the inclination of the lead wire c is also prevented.
