The present invention relates to a reel rotating device, and more particularly, to a reel rotating device that can effectively prevent damage to a reel when holding a reel.

DESCRIPTION OF RELATED ART Conventionally, the winding apparatus of the carrier tape which mounts a chip-shaped electronic component to the reel, and the winding apparatus of the tape which performs the said reel exchange automatically are used. This winding apparatus is equipped with the rotating shaft which can hold | maintain a reel, and it is possible to wind up the carrier tape to send out sequentially to a reel by attaching and rotating a reel to this rotating shaft. Here, as a structure of a rotating shaft and a reel, the thing of the type shown in FIG. 6 is known.

In the same figure, the rotating shaft 80 is provided with the shaft part 81 formed in the shape of the round rod which tapered gradually, and this shaft part 81 is provided every 120 degree | times of the circumferential direction of this shaft part 81, and the shaft part is made through the elastic member which is not shown in figure. Three blade members 82 provided so as to be protruding from the outer peripheral surface of 81 are provided. Moreover, the reel 83 is formed in the cylindrical rotation center hole 84 which can pass the said shaft part 81, and the inner surface side of this rotation center hole 84, and each said wing member Three groove-shaped accommodating portions 85 having a shape corresponding to 82 are provided.

In such a configuration, when the belt-shaped carrier tape (not shown) is wound on the reel 83, the reel 83 is first conveyed by a predetermined arm member to move the shaft portion 81 into the rotation center hole 84. Plug in. At this time, when the positions of the wing member 82 and the receiving portion 85 do not match, the wing member 82 is buried in the shaft portion 81 in response to the elasticity of the elastic member. From this state, the reel 83 and the rotation shaft 80 are rotated relative to coincide with the positions of the wing member 82 and the receiving portion 85, whereby the wing member 82 returns to the initial position to accommodate the receiving portion 85. Housed therein, and the reel 83 is held by the rotation shaft 80. Then, after positioning the reel 83 at a predetermined angle, in order to fix the lead end of the carrier tape to the reel 83, a groove formed in the reel 83 with the lead end through a delivery device (not shown). After the insertion into the 83A, the tape is wound on the reel 83 by rotating the rotary shaft 80.                         

However, in such a configuration of the rotary shaft 80, when the processing accuracy of the reel 83 is low, that is, when the formation position of the accommodation portion 85 is shifted or the width of the accommodation portion 85 is narrow, the shaft portion ( There arises a problem that 81 cannot be inserted into the rotation center hole 84. Therefore, when forming the rotation center hole 84 and the accommodating part 85, it is good to provide sufficient clearance in these shapes, but in this case, the reel 83 will generate | occur | produce, and the position of the reel 83 will be provided. This results in a problem that the bet becomes unstable, making it difficult to insert the lead end of the tape into the groove 83A.

In addition, when the reel 83 is set on the rotation shaft 80, the blade center 82 is inserted in such a way that the inner circumferential surface of the rotation center hole 84 is scratched, so that the rotation center hole 84 is wound. There is also a problem that the center of rotation hole 84 breaks, especially when the reel made of paper is used. In addition, in order to set the reel 83 on the rotating shaft 80 having the wing member 82, a reel 83 that is a dedicated article corresponding to the shape of the wing member 82 must be prepared. There is a problem.

By the way, the structure which inserts a rotating shaft into the revolving center hole of a reel is patent document 1 (Unexamined-Japanese-Patent No. 9-314968), patent document 2 (Japanese Unexamined-Japanese-Patent No. 10-148889), and patent document 3 (Japanese Unexamined-Japanese-Patent No. 9-314968). 11-208049). In these documents, the rotating shaft is provided with protrusions protruding from the outer circumferential surface thereof, and the reels are held on the rotating shaft by accommodating the protrusions in groove-shaped notches formed in the rotation center hole of the reel.

However, in Patent Documents 1 to 3, in order to maintain the holding function of the reel by the rotating shaft, the material of the reel should have a hardness that can withstand the force acting between the projection and the notch. For this reason, in the case where the reel is formed of a relatively soft material such as paper, if a strong rotational force acts on the reel, the notch may be destroyed by the enormous stress generated at the periphery of the notch.

The present invention has been devised in view of such a problem, and its object is to hold the reel in the same way as to sandwich the reel to prevent damage to the reel, and the reel is irrespective of the shape of the center of rotation of the reel. It is to provide a reel rotating device that can be maintained reliably to increase the versatility.

In order to achieve the above object, the present invention provides a reel rotating device having a holding portion for holding a reel capable of winding or unwinding a tape.

The said holding part adopts the structure that it is provided so that rotation force may be provided to the said reel by sandwiching a pair of flange-shaped member which forms the said reel. According to such a structure, a reel can be hold | maintained without inserting a shaft member in the rotation center hole of a reel like a conventional example. As a result, the reeling of the reel can be prevented and the reel can be accurately positioned. Therefore, even when the lead end of the tape is inserted into the groove formed in the reel, this can be performed stably. In addition, it is possible to make the rotary device rich in versatility by eliminating the necessity of using a reel made of a dedicated product.

In the present invention, the holding part includes a main part in contact with an outer side of one flange-shaped member and a follower part in contact with an outer side of the other flange-shaped member, and the main part and the driven part are separated from each other and accessible to each other. It is preferable to adopt the structure of being installed. According to such a structure, since the main drive part and the follower part contact | connect the outer side of a flange-shaped member, the damage of the center of rotation hole at the time of setting of a reel and the rotation can be prevented beforehand.

Moreover, the said main drive part and the follower part can also adopt the structure that the contact part with a reel has an anti-slip structure. By adopting such a configuration, the reel can be reliably maintained, and it becomes possible to stably provide the rotational force of the main drive portion to the reel.

Moreover, the said holding part is also preferably employ | adopted that it is provided on the axis line of the cylindrical rotation center hole of a reel, and has a positioning shaft part which can be inserted in the said center hole. In such a configuration, the reel positioning can be performed without difficulty, and the reel center of rotation can be maintained more accurately.

In addition, the term which shows the direction or position in this specification shall be used on the basis of FIG. 1 unless there is particular notice.
