Description

200413232 Π) 发明. Description of the invention [Technical field to which the invention belongs] The present invention relates to a rotating device of a reel, and more specifically, to a rotating device of a reel that effectively prevents damage to the reel while holding the reel. [Prior art]

I know! Since the use of a conveyor belt that can load wafer-type electronic parts @ Φ on the reel, or a conveyor belt reel device that can automatically replace the reel ° The reel device is equipped with a rotation that can hold the reel The shaft is a shaft on which a reel is mounted and rotated, so that a conveying tape sent out in sequence can be wound on the reel. Here, the structure of the rotating shaft and the reel is known as the type structure shown in FIG. 6.

In FIG. 6, the rotating shaft 80 is provided with a shaft portion 8 1 that is tapered to form a round rod shape at the front end, and is provided at intervals of 120 degrees in the circumferential direction of the shaft portion 81. At the same time, there are three pieces of wing members 8 2 that can be seen on the outer peripheral surface of the shaft portion 81 through an elastic member (not shown). In addition, the reel 8 3 ′ is provided with a cylindrical rotation center hole 8 4 through which the shaft portion 81 can be inserted; and “is formed on the inner surface side of the rotation center hole 8 4 and has a shape that can be adapted to the above-mentioned wing member 82. The three groove-shaped receiving section 85. In such a configuration, when a not-shown conveyance tape is wound on the reel 8 3 ', first, the reel 8 is transferred by a designated arm member, and the shaft portion 8 1 is inserted into the rotation center hole 8 4. At this time, if 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 against the elastic force of the elastic member. From this state, relative rotation of the reel 8 3 and the rotation -4- (2) (2) 200413232 to the rotary shaft 80 to make the positions of the wing member 82 and the receiving part 85 coincide, can restore the wing member 82 to the initial position. And it is accommodated in the receiving part 85, and the reel 83 is hold | maintained on the rotating shaft 80. Next, after positioning the reel 纟 3 at a predetermined angle to be held, in order to fix the leading end of the conveying belt on the reel 83, the leading end is inserted into a groove formed on the reel 83 through a feeding device (not shown). After 8 A, the rotating shaft 80 is rotated to take up the transport tape on the winding shaft 83. However, the configuration of the rotating shaft 80 as described above is when the processing accuracy of the reel 83 is low, that is, when the position where the receiving portion 85 is formed is different, or when the width of the receiving portion 85 is too narrow. This causes a problem that the shaft portion 81 cannot be inserted into the rotation center hole 84. Therefore, in the formation of the rotation center hole 84 and the receiving portion 85, although the shape of these members can be set sufficiently loose to solve the problem, it will cause the reel 83 to become too loose, making the positioning of the reel 83 unstable. This causes a problem that it is difficult to insert the leading end of the conveyer belt into the groove 8 3 A. In addition, when the reel 8 3 is arranged on the rotation shaft 80, most of the conditions are that the wing member 82 may touch the inner peripheral surface of the rotation center hole 8 4 and then be inserted thereinto, so the rotation center hole 8 4 is easy to be damaged. In particular, when a paper-made reel is used, the rotation center hole 8 4 may be broken. Furthermore, in order to arrange the reel 83 on the rotating shaft 80 having the wing member 82, it is necessary to prepare a special product Scroll 8 3 corresponding to the shape of the wing member 82, so that the product cannot be made universal. Therefore, there are also configurations in which a rotation shaft is inserted into a rotation center hole of a reel, which are disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 9-314968 (3) 200413232) and Patent Document 2 (Japanese Patent Application Laid-Open; [〇_; [4 8 8 8 9] and Patent Document 3 (Japanese Patent Application Laid-Open No. 1 i_2 〇8 ο "). In these documents, the 'rotation shaft is provided with protrusions protruding from its outer peripheral surface. The reel is held on the rotation shaft by receiving the protrusion in a groove-shaped notch 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 rotating shaft to the reel, the material of the reel must have hardness that can withstand the force between the protrusion and the notch. Therefore, if a reel is formed of a relatively soft material such as paper, when a strong rotational force acts on the reel, it is feared that the stress generated around the notch will damage the notch. [Summary of the Invention]

On the other hand, the other end side (right end side) of the shaft body 43 is fixed to the auxiliary support plate 45 on the right side than the support plate 37 so as not to be rotatable. As shown in FIGS. 3 and 4, a plate member 47 having a substantially elliptical planar shape is mounted on the left side of the flange section 44 in the third figure, and is mounted below the plate member 47. There are sensors 48 that can detect the rotation angle of the reel R. A lead wire 49 extending from the sensor 48 is connected to a control device (not shown) through a small hole 44A formed in a lower region of the flange portion 44 and the shaft body 43. In addition, "drawing number 5 1" in the figure 1 refers to the push-out plate of the reel R.

Here, the cylindrical rotation center hole R 1 of the reel R is arranged on the rod 3 3 A of the positioning cylinder 3 3 from a transfer device (not shown), and then the arm member 3 is shown in FIG. 5. The flange-shaped member R4 of the reel R is opposed to the driving rotor 19 side in the upright position. To keep the reel R on the holding portion 13 from this state, first, advance the lever 3 3 A to the extent that a certain amount of clearance is generated between the rod 3 and the front end of the positioning shaft portion 16 (Fig. 5). Middle two-dot dotted line). Next, start the clamping cylinder 30 to move the driven rotor 27 to the right. As shown in the figure, the positioning shaft portion 16 is inserted into the cylindrical rotation center hole R 1 of the reel R, and Flange structure -10- (8) (8) 200413232 piece R4 is pressed against the contact surface of the active rotor 19;! 9 A. As a result, the reel R is sandwiched between the driving rotor 19 and the driven rotor 27, and in this state, the drive unit 15 rotates the crotch 20 and the driving rotor 19 to impart a rotational force to the reel. R, following this rotation, the driven rotor 27 also rotates while pushing the reel R toward the driving rotor 19. Here, when the unillustrated conveyance tape is wound on the reel R, first, the reel R is rotated several times. At this time, the sensor 48 will detect the position of the circular hole R6 of the reel R to make the reel at a certain cyclone angle and stop the rotation of the reel R. Next, the leading end of the conveying tape is inserted into the groove r5 of the reel R via a feeding device (not shown), and the reel R is rotated in this state to keep the leading end in the groove r5. When the reel R is finished with the conveying belt, the rod 3 3 A of the positioning cylinder 33 will approach the positioning shaft portion 16 again, and the driven rotor 27 will leave the reel R at the same time.

Therefore, in such an embodiment, when the reel R is to be held, the driving rotor 19 and the driven rotor 27 are in contact with the outside of the flange-shaped member R4, so that the load applied to the reel R can be changed. It is very small, so that damage to the reel R can be effectively prevented. In this way, even if the reel R is a paper product, it can be supported without hindrance. Therefore, the degree of freedom in forming the reel R can be increased. Although the best structures and methods for implementing the present invention include the structures and methods described above, the present invention is not limited thereto. -11-(9) (9) 200413232 That is, although the present invention mainly has specific illustrations of specific embodiments, and its description has been made, it should be within the scope of not departing from the technical idea and purpose of the present invention. The operator can make various modifications to the embodiment described above in shape, number, position or direction, and other detailed structures. Therefore, the descriptions of the shapes and the like disclosed above are illustrative examples for the reader to easily understand the present invention, so they are not the parts to be limited by the present invention. Therefore, some or all of the members defined by these shapes and the like are excluded. The name description is also included in the present invention. For example, the above-mentioned reel R has the same configuration as the conventional example for convenience of explanation, but various design changes can be made as long as the driving part 11 and the driven part 12 can hold the reel. However, when the groove R5 or the round hole R6 is provided as in the above-mentioned embodiment, it is advantageous in that a configuration capable of automatically holding the leading end of the conveying belt can be adopted. In addition, in the above-mentioned embodiment, although the configuration is such that only the driven rotor 27 can be moved in the left-right direction, it may be configured so that only the driven rotor 19 or the driven rotor 27 and the driven rotor 19 can be moved. Anyone can move to the left and right to make these structures separate and approach each other. Further, the above-mentioned rotating device 10 may be adapted to apply a transport belt to a take-up reel. As described above, according to the present invention, since the holding portion is provided to sandwich the flange-like member of the reel so as to impart rotational force to the reel, it is not necessary to insert the shaft member at the center of rotation of the reel as in the conventional example. The reel can be reliably held in the hole, so that the reel can be prevented from loosening. In addition, it can be supported regardless of the shape of the rotation center hole of the scroll shaft, which makes it universal. -12- (10) 200413232 In addition, 'the driving part and the driven part constituting the holding part are arranged to contact the flange The outer sides of the shaped members can be separated and approached to each other at the same time. Therefore, when the reel is held, the load applied to the reel can be eased, and damage to the reel can be avoided.

In addition, when the contact portions of the driving portion and the driven portion that are in contact with the reel have a slipping structure, the holding force of the reel can be enhanced, and the rotating force of the driving portion can be stably applied to the reel. In addition, since the holding portion includes a positioning shaft portion that can be inserted into the rotation center hole of the reel, the positioning of the reel can be easily performed while holding the reel, and the position of the rotation center of the reel can be maintained accurately.
