Take-up reel 18 having a circumferential surface formed in a tooth shape
It consists of and.

The winding gear 17 is a take-up reel 18
It engages with the teeth on the peripheral surface and is allowed to rotate only in the direction opposite to the rotatable direction of the take-up reel 18. That is, when the winding gear 17 and the take-up reel 18 are in mesh with each other, rotation is allowed only in the take-up direction of the take-up reel 18. A take-up cap 19 is attached to the take-up reel 18 so as to face the take-up reel 18, and the top tape 9 is wound between the take-up reel 18 and the take-up cap 19.

The pressing surface 12b of the feed lever 12 is constantly biased upward in FIG. 4 by the feed spring 21, and the take-up lever 13 is always upward in FIG. 4 by the take-up spring 22 fixed to the frame 10 side. The gear arm 16 is urged, and the urging spring 14 presses the winding gear 17 against the peripheral surface of the take-up reel 18.
Further, tension rollers 24 and 25 for suspending the top tape 9 are rotatably arranged on the frame 10, and a charge roller 26 is rotatably provided on an end portion of the feed lever 12. Top tape 9 is taping component 8
After being peeled off, it is suspended by the tension rollers 24 and 25 and wound on the take-up reel 18, and is pulled up by the charge roller 26 between the tension rollers 24 and 25 in FIG.

Next, the operation of the top tape winding portion C having the above-mentioned structure will be described with reference to FIG. First, from the initial state in which the feed lever 12 is not pressed down as shown in FIG. 8A, as shown in FIG. 8B, the pressing surface 12b at the tip of the feed lever 12 receives the pressing operation from the electronic component mounting apparatus B. The feed lever 12 swings around the fulcrum shaft 11. By swinging the feed lever 12,
The take-up lever 13 is rotated about the fulcrum shaft 11 by the pulling force of the take-up spring 22 so that the projection 13a of the take-up lever 13 follows the inner wall of the opening 12a of the feed lever 12. , Gear arm 16
The take-up reel 18 is rotated in the take-up direction while the take-up gear 17 attached to the tip of the take-up gear 17 stops rotating.

Then, as shown in FIG. 8C, when the pressing operation is released and the feed lever 12 returns to the initial state due to the elasticity of the feed spring 21, the projection 13a of the take-up lever 13 opens the feed lever 12. The winding lever 12 is pulled back by coming into contact with the inner wall surface of the portion 12a. Then, the winding gear 17 rotates, meshes with the teeth of the take-up reel 18, and returns to the initial position. At this time, the take-up reel 18 has the one-way clutch 18a.
Since the rotation in the direction opposite to the winding direction is blocked by, the top tape 9 is stopped in a wound state without rotating.

The top tape 9 is slightly pulled toward the take-up reel 18 when the state shown in FIG. 8 (a) is changed to the state shown in FIG. 8 (b), and is shown in FIG. 8 (c). When shifting to the state, the drawn top tape 9 is returned. As a result, the top tape 9 that is pulled back in the component supply unit D described later in detail is returned.

The stable winding operation can be performed without causing a delay until the teeth are engaged with each other. As a result, the top tape can be reliably wound up, and the reliability of the winding operation can be improved. Further, since the gears are meshed with each other, the operation is smooth, and the frequency of meshing one tooth is significantly reduced, so that the durability is improved. Further, since the gears are meshed with each other, the operation noise is extremely low, which can greatly contribute to the silence of the entire apparatus. And
Since the mechanism itself is simply configured, for example, maintenance is easier, thinner, and lower cost than a configuration in which a plurality of one-way clutches are coaxially combined.

In the component supply device shown in FIGS. 3 to 7, the top tape winding portion C is provided on one side of the frame 10.
Although it is a single type configuration in which the component supply section D and the driving force transmission section E are provided, it may be a double type in which the configurations C, D and E are provided on both sides of the frame. An example of this case is shown in FIG. FIG. 9 is a cross-sectional view showing a double type component supply device A corresponding to FIG. 7.

There is. That is, the opening (slit) 43 formed in the shutter 32 is formed so that the upper surface of the housing portion for the taping component is narrowly opened and the upper surfaces on both end sides in the width direction of the top tape are widened. The peeling of the top tape 9 by the shutter 32 is performed by the guide portion 32d that presses the upper surface of the taping component 8.

Next, the operation of the component supply section D will be described with reference to FIGS. 12 is a perspective view of an essential part of the component supply unit D, and FIG. 13 is a sectional view of the fixing plate 40, the shutter 32, and the taping component 8 corresponding to FIG. First, as shown in FIGS. 12 (b) and 13 (b), the link 30 is pushed down by the electronic component mounting apparatus B via the feed lever 12 from the initial state shown in FIGS. 12 (a) and 13 (a). Then, the pin 31a of the swing lever 31 presses the engaging groove 32a of the shutter 32, and the shutter 32

Further, the top tape 9 is slightly attracted to the component supply section D side by the shutter 32 sliding, but the charge roller 26 of the top tape winding section C shown in FIG. 8C returns to the initial position. As a result, the top tape 9 is canceled by being slightly returned.

As described above, according to the shutter 32 having the above structure, the portion along the bonding line 8d between the top tape 9 and the tape-shaped body 8a is retracted, so that the top tape 9 should be held by the pressing portion 32b. Even if it is about to be pulled into the lower surface of the
Since b does not exist above, it is prevented from being drawn below the shutter 32. It is also prevented by the central portion of the top tape 9 being pushed by the protruding piece 32c. Further, it is possible to reliably prevent the top tape 9 that is delayed in peeling due to the combination thereof from being pulled below the shutter 32.

Further, since the projecting piece 32c covers the storage portion 8b of the taping component 8 after the top tape 9 is peeled off by the opening 43, the storage portion 8b can be securely held without the electronic component 2 in the storage portion 8c popping out.

The electronic component 2 in the storage portion 1b can be reliably held by being covered. Further, even if the top tape 9 is likely to be pulled into the lower surface of the shutter 32 as described above, this can be prevented, and it is possible to prevent the mounting work from being disturbed. Then, by widely opening the slits in both the upstream and downstream directions of the taping component, it is possible to quickly start peeling on both widthwise end sides of the top tape of the taping component, and a more stable peeling operation. Obtainable. Also,
By forming a plurality of projecting pieces, it is possible to reliably peel off the top tape even when a large-sized component having a wide width is prevented from protruding.
