A plurality of leaf springs 16 in which a mounting piece 12 and a bed 15 provided at a central portion on the back side of a flat conical distribution table 10 are inclined.
Are connected by A configuration in which a movable core 17a is provided on the mounting piece 12 at a predetermined interval from a magnet coil 18 mounted on a bed 15 is known.

い方が望ましい。[0003] When the movable core 17a is attracted by energizing the magnet coil 18, such a dispersion feeder is used.
The suction direction is the vertical direction, but the plurality of leaf springs 16 supporting the dispersion table 10 directly on the bed 15 are inclined in the same direction in the circumferential direction (usually an inclination angle of 20 ° with respect to the vertical direction). ), A reciprocating spiral vibration motion is performed with respect to the center axis a. The reciprocating spiral vibration is composed of a component in a rotational direction and a component in a vertical direction with respect to the center axis a. For an object to be processed having poor dispersion characteristics due to such vibration, for example, as shown in Table 1, it is desirable that the reciprocating helical vibration of the conical dispersion table is large, and in particular, the object to be processed is separated from the surface of the dispersion table. It is desirable that the vertical vibration component is large as an operating component for the operation.

Although the vertical vibration component is the same as the vertical vibration component of the movable core 17a at any position of the dispersion table 10 and is constant, the vibration component in the rotation direction naturally has a large portion near the outer periphery in the radial direction.

吸引力はギャップの２乗で弱まるので不利となる。However, such a conventional distributed feeder has the following problems. (1) with respect to the angle in the vertical direction of the leaf spring supporting the dispersion table, with respect to the amplitude gamma 1 of the leaf spring because it is 20 °, the amplitude h 1 in the vertical direction is h 1 = γ 1 sin20 ° = 0.342γ 1 ----- (1) and a small value. (2) It is necessary to increase the amplitude of the leaf spring in order to achieve the desired purpose when the vibration component in the vertical direction is large, and the durability (fatigue limit) of the leaf spring decreases. (3) If the amplitude of the leaf spring is increased, the vibration component in the rotation direction becomes too large in the vicinity of the outer periphery of the dispersion table, so that the momentum of the object to be processed becomes too large, and normal dispersion characteristics cannot be obtained. (4) If the amplitude of the leaf spring is increased, the momentum near the outer periphery of the distribution table increases, and a driving force for the magnet coil is necessary.Therefore, it is necessary to prepare a large-capacity vibration magnet coil. There is. (5) In the conventional method, it is also possible to maintain the balance of the vibration component between the vertical direction and the rotation direction of the dispersion table by inclining the inclination angle of the leaf spring by about 45 ° from the vertical direction. The vibration component in the gap direction between the coil and the magnet coil increases. This is disadvantageous because the attractive force of the magnet coil is weakened by the square of the gap.

質的に板バネ16の厚み方向の曲げ負荷条件に近いもので
ある。In the conventional dispersion feeder, the mounting angle of the leaf spring 16 is about 20 ° with respect to the vertical direction, and the principal load stress is essentially the leaf spring against the circumferential vibration of the dispersion table. This is close to the bending load condition in the thickness direction of No. 16.

のような機能性を得ようとするには、板バネ16の傾斜を
大きくすることが一つの要件と考えられる。When handling an object having poor dispersion characteristics, the reciprocating spiral vibration is applied to the dispersion table as described above, so that the vertical vibration component as well as the circumferential vibration component can be increased. It is desirable to do. In order to obtain such functionality, increasing the inclination of the leaf spring 16 is considered as one requirement.

とは、その目的に反するから採用し難い手段である。However, as the inclination angle of the leaf spring 16 approaches the horizontal direction, the stress generated in the leaf spring 16 becomes larger due to bending in the width direction. Therefore, as a means of reducing the stress in the width direction of the leaf spring, the width dimension of the leaf spring 16 is shortened, and in order to obtain a necessary spring constant, a method of increasing the number of combined leaf springs 16 is also considered. In this case, the bolt mounting hole for mounting the leaf spring 16 becomes weak, and it becomes difficult to maintain the spring constant of the leaf spring 16. However, it is necessary to increase the dimension of the leaf spring holding plate in the mounting portion in the length direction of the leaf spring. Since it is preferable that the dimension in the height direction is smaller as the dispersion feeder, increasing the number of leaf springs and increasing the overall thickness of the mounting portion is a means that is difficult to adopt because it is contrary to its purpose. .

(ii) the amplitude x 1 in the rotation direction of the plate sprung suction direction to the amplitude t 1 of the conventional method is x 1 = t 1 tan20 ° = 0.364t 1 ----- t 1 = 2.75x 1 present invention method in amplitude x 2 in the rotational direction of the suction direction of the amplitude t leaf sprung against 2 to obtain the amplitude of the x 2 = tz sin15 ° = 0.259t 2 ----- t 2 = 3.86x 2 the same direction of rotation t 2 / t 1 = 3.86x / 2.75x = 1.4 times the gap is required. (iii) However, since the amplitude of the leaf spring for achieving the purpose of increasing the vertical vibration component can be made smaller than that of the conventional method, the durability of the leaf spring can be improved. (iv) Even if the amplitude of the leaf spring is increased in order to increase the vertical vibration component, the vibration component in the rotation direction near the outer periphery of the dispersion table can be reduced as compared with the conventional method. Easy dispersion characteristics are easily obtained.

させる必要がある。By adopting the structure of the present invention, a dispersion feeder having improved dispersion characteristics as compared with the conventional one can be obtained. However, as described above, the leaf spring supporting the dispersion table 10 is used. When the tilt angle of the 16 is 20 ° or more with respect to the vertical direction, specifically, at a maximum of 45 °, the displacement amount in the rotation direction becomes large. Therefore, as a matter of course, the load stress on the leaf spring 16 increases with respect to the vibration in the rotational direction. In other words, as the inclination angle of the leaf spring 16 increases, the load stress of the leaf spring becomes greater due to the bending stress in the width direction of the leaf spring than the conventional bending stress in the thickness direction of the leaf spring. Therefore, it is necessary to cope with the increase in the applied stress as compared with the conventional case where the inclination of the leaf spring is small.

In addition, while adopting the mounting means of the flexure structure 20, a leaf spring
In order to more securely fix the 16 mounting brackets 13A and 14A, it is preferable to increase the size of the leaf spring holding plate 22 in the length direction of the leaf spring.
