A core supply path 83 for supplying the core 25 is arranged in an inclined state in the core receiving portion 82 formed by the receiving member 80 between the core 25 and the core receiving portion 82 . In FIG. 9, reference numeral 85 denotes a regulating device for supplying the cores 25 housed in the core accommodating portion 2 shown in FIG. 1 to the core receiving portion 82 one by one. Core body 25
As shown in FIG. 9, the core body 25 is supplied to the core receiving part 82 so that its outer peripheral surface part 26 is received by the receiving surface part 77. As the holding member 10 moves forward, the cylindrical portion 33 is moved as shown by the dashed line in FIG.
, one core body 25 is pushed into the guide path 27, and accordingly, one core body 25 is extruded from the outlet end 27b of the guide path 27, and the extruded core body 25 is held by the first and second holding members 10 and 12. The first,
The second flanges 11 and 13 are the winding flanges 3 of the core body 25.
Form 0,50.

In this embodiment, the core body 25 held in this manner is securely held by a holding tool 86 that is slidably attached to the rotating shaft 48 of the second holding member 12. As shown in FIG. 8, in this embodiment, the retainer 86 faces the second flange 13 of a disc body 89 having an insertion hole 87 in the center through which the rotating shaft 48 is inserted. A side surface (inner surface) 90 is provided with needle-like protrusions 92 projecting through holes 91 provided at four corners of the peripheral edge of the fixed portion of the contact plate 49. Note that the retainer 86 is configured so that the groove 93 provided in the insertion hole 87 and the rotating shaft 48 come into contact so that the projection 92 of the second holding member 12 is always inserted through the through hole 91 even when the second holding member 12 rotates. The locking protrusion 94 provided in the axial direction on the portion near the plate portion 49 is engaged with the locking protrusion 94 to prevent rotation and allow the plate portion 49 to slide. Then, as the retainer 86 approaches the abutting plate portion 49,
The protrusion 92 bites into the side surface of the core 25 (the third
4 and 13), and when the retainer 86 separates from the abutment plate 49, the protrusion 92 is removed from the through hole 91. Note that the amount of bite of the protrusion 92 into the core body 25 can be adjusted according to the width of the core body 25. Furthermore, the sliding movement of the retainer 86 is caused by the static ring 95 attached to the retainer 86 and the static ring 95, as shown in FIG. 4, for example.
a swinging link 96 whose one end is rotatably pivoted and swings about the center, and a fixed link 97 whose base is fixed to the sliding portion 35 of the first holding member 10 and extends laterally. , a sliding means 100 consisting of a connecting link 99 whose both ends are rotatably connected to the other end of a swinging link 96 and the tip of a fixed link 97.
This is performed in conjunction with the movement of the first holding member 10. As shown in FIG. 11, the stationary ring 95 has a circular recess 102 on its inner surface into which a bearing 101 is fitted, and an insertion hole through which the rotary shaft 48 can be inserted through the central portion of the circular recess 102. The bearing 101 has a hole 103, and a cylindrical portion 104 (see FIG. 10) that protrudes from the outer surface of the disc body 89 of the holder 86 is fitted into the inner ring of the bearing 101. Therefore, even if the holder 86 rotates due to the rotation of the rotating shaft 48, the stationary ring 95 does not rotate.

As mentioned above, the core body 25 is
When the second holding member 12 is rotated with the protrusion 92 biting into the side surface of the core body 25, the core body 25 rotates, and at the same time, the frictional force generated between the core bodies and The rotating portion 42 of the first clamping member 10 rotates due to the frictional force generated between the core body 25 and the clamping end 10a (see FIG. 3) of the first clamping member 10, and the guide member 9 also rotates. The core body 25, which rotates together and is sandwiched between the first flange 11 and the second flange 13, rotates smoothly and effortlessly.

In FIGS. 4-5, 8, and 13-14, reference numeral 105 denotes a winding start end fixture for fixing the winding start end 106 of the tape-like material 28 to the outer circumferential surface portion 26 of the core body. The winding start end fixing device 105 is attached to the disk body 89 of the holding device 86, and is attached to a sliding rod 108 that can slide in a sliding groove 107 provided in the lower part of the inner surface of the disk body 89. One end is bent inward, and a pressing body holding piece 109 is connected to the tip of the pressing body holding piece 109 which is bent at right angles to the sliding rod 108. The sliding rod 108 is configured to be able to slide without colliding with the sliding rod 90, and a needle-shaped pressing body 110 is provided at the center of the pressing body holding piece 109 to project inwardly. The end of the rod 112 of an air cylinder 111 fixed to the upper part of the inner side surface 90 of the disk body 89 in parallel with 108 is fixed to the tip of the pressing body holding piece 109, and the sliding rod 108 is moved by the expansion and contraction of the air cylinder 111. It is configured so that it can be slid, and therefore the pressing body 110 can be moved forward and backward relative to the outer circumferential surface portion 26 of the core body 25. Note that the pressing body 110 is formed in the radial direction astride the abutting plate part 49 and the second collar part 13 by the disc body 89 approaching the abutting plate part 49 of the second holding member 12. It is inserted through the long hole 113 and can move forward and backward while being inserted through the long hole 113. As shown in FIG.
The winding start end 106 is pressed and fixed to the outer circumferential surface portion 26 by performing a forward movement while being located between the winding end 106 and the winding start end 106 .

After the core body 25 has wound up the tape-like material 28 for the required length while the pressing body 110 keeps the winding start end 106 fixed, the pressing body 110 is separated from the winding ball 115 by the detaching means 114. (See Figures 12-13). In this example,
The winding start end fixing means 105 is attached to the disk body 89 of the holder 86, and since the pressing body 110 and the protrusion 92 move together, the sliding means 100 is attached to the detaching means 114. (See Figure 4).

As a result of configuring the winding start end fixing device 105 to have the pressing body 110 that moves forward and backward in this way, even when the width of the core body 25 is very small, for example, about 5 mm, the winding start end 106 can be fixed. It can be fixed to the core body 25 easily and quickly.

Operation of the device according to the embodiment Next, the operation of the device 1 according to the embodiment will be explained.

The core 25 supplied to the core receiving portion 82 formed at the entrance end 27a of the guide path 27 of the guide member 9 is transferred to the first clamping member 10 as the air cylinder 56 expands.

The core body 25 being held between the first and second holding members 10 and 12 means that the tip of the rotating portion 42 of the first holding member 10 and the second holding member 12 shown in the above embodiment This includes the case where the core body 25 is directly clamped.

The first flange 11 and the second flange 13 are arranged at the guide path exit end 27b so as to form a winding flange 30, respectively.
In addition, it is sufficient that the winding collar 50 is provided at the clamping end 12a of the second clamping member 12, and is provided independently of the guide member 9 and the second clamping member 12. It may be provided in a non-rotatable manner.

The protrusion 92 of the holder 86 is not limited to a needle-like shape, and the core 25 has the protrusion 92 formed to the extent that the core is prevented from slipping when the core is rotated.
As long as it is held in place, its shape and size are arbitrary. Also, the protrusion 92 bites into the core body 25.
The grooves 1 are not limited to those that cut into the side surface of the core body 25 as shown in the embodiments, but, for example, as shown in FIG.

(Effects of the Invention) The device of the present invention is incorporated into a tape-like material winding device and exhibits the following excellent effects.

The core body is held between the first and second holding members with winding flanges formed at both ends thereof.
Therefore, when winding a tape-like object, the winding can be performed correctly and stably, and the rolled tape-like object can be wound with high commercial value, with the edges of the wound tape-like object being neatly aligned. I can do it. Furthermore, as the core body, an inexpensive round body which does not have a winding collar, which is obtained by cutting a rod-shaped body made of styrene foam or the like into rounds at a required width, can be used as it is, so it is excellent in economical efficiency.

When supplying the core between the first and second holding members, the core is passed through a guide member having a core guide path. However, the core can be reliably supplied between both clamping members, and for example, one core can be gripped from among the stocked cores and the core can be transferred to the first and second gripping members.
The structure for supplying the core is very simple, easy to manufacture, and excellent in economy, compared to the case where an arm-based mechanism for supplying the core between the clamping members is adopted.
