DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode of an automatic reel device according to the present invention will be described below in detail with reference to the accompanying drawings (FIGS. 1 and 2). FIG. 1 is a front view showing an automatic reel device according to the present invention. FIG. 2 is a perspective view showing the automatic reel device of FIG.
This automatic reel device automatically rotates a reel 10 to wind or feed a tape-like article to be wound. For example, it is used as a tape feeder for supplying an electronic component or the like affixed to a resin tape to a mounter device, or a hoop material feeding device for supplying a metal strip-like thin plate as a metal press work.

Reference numeral 20 denotes a rotation shaft, which serves as a shaft for rotation for rotating the reel 10 and is provided in a shaft shape or a rod shape that can rotate around the shaft core. The rotary shaft 20 is fitted in a state of being inserted into the cylindrical main body portion 12 of the reel 10 and is provided so as to hold the reel 10 together with a reel holding portion 30 described later. Reference numeral 22 denotes a reel fixing component, which is provided so as to press and fix the reel 10 when the reel 10 is mounted on the rotary shaft 20. Thereby, the reel 10 can be easily attached and detached.
The shaft core member that serves as the rotation axis of the reel 10 is not limited to the rotary shaft 20 and may be a shaft core member that does not rotate. In that case, the reel 10 can be suitably rotated by providing a reel holding portion 30 described later around the shaft core member in a rotatable manner.

Reference numeral 30 denotes a reel holding unit, which is provided so as to be rotatable about the shaft core integrally with the rotary shaft 20 so as to hold the reel 10.
In the present embodiment, the reel holding unit 30 and the rotation shaft are integrated so that the reel holding unit 30 formed separately from the rotation shaft 20 is integrated with the rotation shaft 20 so that the rotation shaft 20 can rotate about the axis. It is being fixed so that it may not rotate relatively between. The rotating shaft 20 and the reel holding unit 30 may be integrally formed.
Further, the holding surface of the reel holding portion 30 of this embodiment is formed in a disc shape so as to receive and hold the side surface of one flange 14 of the reel 10. For this reason, this reel holding part 30 is a reel mounting board, and can set the reel 10 stably.
In addition, the form of the reel holding part 30 is not limited to this, The reel holding part 30 can be rotated via a bearing with respect to the shaft member supported so as not to rotate as described above. It may be. Further, the portion for holding the reel 10 is not limited to a disk shape formed of a flat plate portion, and other forms may be used as long as the reel 10 can be appropriately held. For example, you may provide the radial part extended to the spoke-shaped radial direction of a bicycle.

Further, the reel holding portion 30 is provided with a circumferential portion 32 so as to be concentric with the axis of the rotating shaft 20. The circumferential portion 32 is provided in a state of protruding in a side wall shape in a direction opposite to the surface side to which the reel 10 of the reel holding portion 30 is attached. Further, the circumferential portion 32 is formed in a band shape having a constant width.
Thus, since the reel holding portion 30 having the circumferential portion 32 is provided, the power of the motor 52 described later can be suitably received, and all the configurations of the reel 10 and the motor 52 and the like are achieved by the base portion 42 described later. Can be suitably supported.
Note that the reel holding portion 30 may have a function of holding the reel 10 as a whole via a portion that contacts the flange portion 14 of the reel 10 and a portion that fits into the cylindrical main body portion 12. For this reason, the circumferential portion 32 described above only needs to be able to rotate together as a part of the reel holding portion 30, and the circumferential portion 32 itself does not need to have a function for holding the reel 10. Therefore, a form in which a disk for attaching the reel and a disk having the circumferential portion 32 are provided together is also included.

Reference numeral 40 denotes a bearing portion, which rotatably receives the rotary shaft 20 by a bearing. Reference numeral 42 denotes a base portion which supports the reel holding portion 30 via the rotating shaft 20 by supporting the bearing portion 40.
Reference numeral 50 denotes a rotation driving means which is installed on the base portion 42 and directly transmits a driving force to the reel holding portion 30 so that the reel 10 is rotated via the reel holding portion 30 and the rotary shaft 20. Is provided.
According to this, the base portion 42 supports the reel 10 via the bearing portion 40, the rotating shaft 20 and the reel holding portion, and also supports the rotation driving means 50 including the motor 52 and the like which will be described later. Accordingly, the reel 10 and the rotation driving means 50 can be supported by the single base portion 42, and the configuration can be simplified, so that the manufacturing cost can be reduced.
Further, since the reel 10 and the rotation driving means 50 can be supported by the single base portion 42, the width of the entire apparatus can be reduced as compared with the case where the motor 52 is directly connected to the conventional rotary shaft 20. . Therefore, the space in the factory can be used appropriately, and productivity can be increased.

Further, the rotation driving means 50 of the present embodiment includes a roller driving mechanism 51 that transmits the power of the motor 52 to the reel holding unit 30 when the driving roller 55 that rotates by the power of the motor 52 contacts the circumferential portion 32. The presser roller mechanism 60 will be described later.
The roller driving mechanism 51 is provided so as to transmit the power of the motor 52 to the reel holding unit 30 when the driving roller 55 comes into pressure contact with the inner peripheral surface 33 provided on the circumferential portion 32 described above. That is, the reel holding portion 30 is rotated by transmitting the power of the motor 52 in the tangential direction of the circumferential portion 32 at one contact point between the inner circumferential surface 33 of the circumferential portion and the outer circumferential surface of the driving roller 55. Yes. In addition, since the driving roller 55 is in contact with the inner peripheral surface 33, the contact surface can be suitably secured and the power can be transmitted appropriately. Because it is a roller, noise is low. Note that the motor 52 is guided by the linear guide portion 45 so as to be movable on the base portion 42 in the press-contact direction (the radial direction of the circumferential portion 32) so that the drive roller 55 is always pressed against the inner peripheral surface 33. It is arranged. In this embodiment, the motor 52 is attached to the base portion 42 so as to be movable in a predetermined section in the vertical direction.
According to this power transmission mechanism, since the diameter of the drive roller 55 is smaller than the diameter of the circumferential portion 32, it has a function as a speed reducer with a large reduction ratio. For this reason, a special reduction device such as a gear is not required, and the configuration can be rationally simplified, and the manufacturing cost can be reduced. Furthermore, power transmission efficiency is high, and energy consumption can be suppressed.

The speed reduction ratio is determined by the ratio of the diameter of the circumferential portion 32 and the diameter of the drive roller 55. Therefore, a desired speed reduction ratio can be obtained by appropriately setting both sizes. For example, if the circumferential portion 32 is formed to have a smaller diameter than the present embodiment and the diameter of the drive roller 55 is not changed, a reduction ratio smaller than that of the present embodiment can be obtained. Further, the circumferential portion 32 does not need to be formed on the outer peripheral edge of the reel holding portion 30, and if it is concentric with the axis of the rotating shaft 20, it is formed in an appropriate size corresponding to a required reduction ratio. do it.
Furthermore, as a material of the driving roller 55, for example, a rubber material having high friction and elasticity can be used in order to efficiently transmit power.
Note that the mounting position of the roller drive mechanism 51 is not limited to this embodiment, and may be installed at another position as long as the power of the motor 52 can be appropriately transmitted as in the embodiment described below. .
Further, the rotation drive means 50 may be a pinion gear instead of the drive roller 55, and the power transmission mechanism may be a gear by using the circumferential portion 32 as an internal gear or the like.

Reference numeral 62 denotes a presser roller which is pressed against the outer peripheral surface 34 corresponding to the inner peripheral surface 33 with which the drive roller 55 of the circumferential portion 32 contacts and is rotatably provided.
In the presser roller mechanism 60 having the presser roller 62, a helical spring (coil spring 64), which is an example of an elastic member, can be used as the pressing means, for example, as shown in FIGS. A coil spring 64 is provided between the spring receiving portion 65 fixed to the base portion 42 and the movable roller receiving portion 63 provided so that the pressing roller 62 is rotatably fixed and slidable on the side surface of the base portion 42. It is arranged.
Although the movable direction of the movable roller receiving portion 63 of this embodiment is the vertical direction, the direction is not particularly limited, and the movable roller receiving portion 63 can be moved in the radial direction (radial direction) about the axis of the rotating shaft 20. It is good to be provided. In addition to the coil spring 64, a rubber material, a leaf spring, a torsion spring, or the like can be employed as the elastic member.
Furthermore, the pressing means of the presser roller 62 is not limited to this, and fluid pressure such as air pressure may be used, for example, the presser roller 62 is rotatably attached to the tip of the rod of the air cylinder device.

In this way, the presser roller 62 is pressed against the outer peripheral surface 34 of the circumferential portion 32, so that the circumferential portion 32 can be suitably sandwiched between the drive roller 55. Thereby, the drive roller 55 can contact the inner peripheral surface 33 of the circumferential portion 32 with an appropriate pressure, and the power of the motor 52 can be suitably transmitted. Further, according to the above-described moving mechanism by the linear guide portion 45 of the motor 52 and the pressing mechanism of the presser roller 62, even when the circumferential portion 32 rotates with a slight eccentricity within a certain accuracy, the eccentricity can be achieved. The drive roller 55 can be brought into contact with the circumferential portion 32 following the rotation, and functions as a kind of eccentricity correction mechanism. That is, variations in dimensional accuracy and play of the rotating shaft of the reel holding unit 30 provided with the circumferential portion 32 can be absorbed and corrected, and the power of the motor 52 can be suitably transmitted to the rotation of the reel holding unit 30. it can. Moreover, since it can correct | amend in this way, the tolerance | permissible_range of the precision and assembly precision of components, such as the circumference part 32, can be expanded, and there exists an advantage which can reduce manufacturing cost.
In order to bring the driving roller 55 into contact with the inner peripheral surface 33 with an appropriate pressure, the present invention is not limited to this embodiment. For example, a mechanism for bringing the driving roller 55 into contact with the inner peripheral surface 33 by mainly using the own weight of the motor 52 disposed on the base portion 42 so as to be movable in a predetermined range in the vertical direction without disposing the presser roller 62. It is good. In such a mechanism, if the elasticity of a spring or the like is used, the pressing force with which the drive roller 55 contacts the inner peripheral surface 33 can be adjusted appropriately.
