The core 3 has a cylindrical shape whose inner peripheral portion is formed in the same rectangular shape as the outer peripheral portion of the winding shaft 2 and has one side open. When it is inserted into the bracket, the angular shape serves as a detent for preventing the rotation of both 2 and 3 in the rotation direction.

A mounting piece 10 is protruded from the inner periphery of the winding core 3 in correspondence with the receiving projection 8 provided on the winding shaft 2. 3 is provided with a first sloped body 11 that slides along the upper surface of the receiving projection 8 and a second sloped body 12 that slides in contact with the locking edge 9 when the core 3 is removed. It is.

The first slant body 11 and the second slant body 12
Is approximately 45 with respect to the surface in the length direction of the mounting piece 10.
The mounting piece 10 is formed of an elastic material such as a synthetic resin, so that it can be easily undulated (oscillated) in the radial direction and wound. The attachment / detachment operation of the core 3 is performed smoothly.

Further, the easy-tape releasing means 1 comprising an annular ridge 13 and an annular winding body 14 are attached to the winding shaft 2 and the winding core 3.
5, of which the annular ridge 13 is provided on the inner peripheral portion of one side plate 4 so as to be continuous or intermittent.

The annular ridge 13 may be formed stepwise with respect to the side plate 4 as shown in FIG. 3B, and the corners thereof may be formed as shown in FIG. If a round shape or other chamfering is performed, the engagement state of the winding body 14 described later becomes smooth and favorable.

The above-mentioned wound body 14 is such that the cover tape d is wound on the inner peripheral portion of the other side plate 5 to engage with the outer peripheral portion of the annular ridge 13 and to be wound on the outer peripheral surface thereof. It is formed in an open tubular shape.

The ring projection 13 and the annular winding body 14 may have a relative configuration provided on the other side plate 5 and one side plate 4.

The inner diameter L2 of the leading end of the winding body 14 is formed smaller than the outer diameter L1 of the annular ridge 13 by w.
When the winding body 14 is fitted to the annular ridge 13, the leading end of the winding body 14 spreads outward and is exaggerated in FIG. 4A, and is wound around the outer peripheral surface of the winding body 14. The start end surface of the cover tape d and the outer peripheral surface of the winding body 14 are configured to be parallel.

As a result, as shown in FIG. 4 (b), when the wound body 14 is removed from the annular ridge 13, the leading end of the wound body 14 is restored to the original position and wound in a layer. The cover tape d is loosened or bent by the gap w, so that the cover tape d can be removed from the winding body 14 very easily.

When removing the cover tape d,
In order to easily expand the winding body 14 in the diameter direction,
This is achieved by providing a plurality of cuts 16 on the winding body 14 that open toward the outer edge.

When the cover tape d is wound around the cover tape take-up device A, as shown in FIG. Through the cover tape d, then pull out the winding start end of the cover tape d from another adjacent or predetermined cut 16 to the outside of the winding body 14 and project it out. The protrusion d1 is temporarily fixed by being pressed and fixed by the cover tape d wound around the protruding portion d1.

Therefore, the apparatus A and the method for winding the cover tape for a taping member of the embodiment of the present invention configured as described above have the following effects.

First, at the time of supplying the electronic component b to the electronic component mounting machine F, a taping member t wound around a predetermined length on a tape reel e is set in the electronic component feeder H, and the cover tape winding device A is provided with a cover tape winding device A.

When pressed, it is temporarily fixed as shown in FIGS.

In this state, the winding core 3 is transferred to the winding shaft 2 as shown in FIG.
As shown in (1), the mounting piece 10 is inserted into the receiving projection 8 (the positioning is easily performed because the winding shaft 2 and the winding core 3 are formed in the same square).

Then, as shown in FIG. 5A, the first slanted body 11 of the mounting piece 10 abuts on the inclined receiving projection 8 and the core 3 is pushed in by the swing of the mounting piece 10. And move to the back.

By this movement, finally, when the first inclined body 11 gets over the receiving protrusion 8, the movement limit of the core 3 is reached, and as shown in FIG.
2 engages with the locking edge 9 connected to the receiving projection 8, so that the core 3 is detented, and the cover tape winding device A is configured as shown in FIG.

Further, in this cover tape winding device A, when the winding core 3 is attached to the winding shaft 2, the winding body 14 is fitted into a ring projection 13 protruding from the side plate 4 of the winding shaft 2. As a result, as shown in an exaggerated manner in FIG.
Is widened outward, and the diameter of the distal end of the winding body 14 is larger than the gap w before attachment.

Then, with the supply of the electronic component b to the electronic component mounting machine F by the feed means 20 provided in the electronic component feeder H, the cover tape winding device A is interlocked with the feed means 20 (in the case of single drive). Then, the core 3 rotates, and the cover tape d is sequentially wound around the outer periphery of the winding body 14 of the core 3.

In this way, when the cover tape d reaches the predetermined winding amount, the core 3 is pulled out toward the outside in the axial direction, and when a constant pulling force is applied, the core 3 is engaged with the locking edge 9. The second inclined body 12, which has been sliding,
Since the mounting piece 10 is disengaged from the state shown in FIG. 5B by the swing of the mounting piece 10 as shown in FIG. 5A, the core 3 comes off the winding shaft 2 as shown in FIG.

Then, since the diameter of the winding body 14 of the winding core 3 is returned to the original state, the cover tape d wound with a predetermined tension on the winding body 14 is, as shown in FIG. 1
4, a gap w is formed between the outer peripheral surface of the leading end portion and the winding start portion of the cover tape d.
Even if the cover tape d is hardly wound, the winding is loosened and bent, and the cover tape d can be easily extracted in the direction of the arrow x.

Further, when the winding of the cover tape d is loosened, the pressing force of the projecting portion d1 by the next winding of the cover tape d is also released.
In (b), the extraction in the direction of the arrow x is not hindered at all.
