After the passage of time, the damming mechanism 40 is switched to the open state. After that, the control unit 70 repeats the control of controlling the damming mechanism 40 again to the damming state and the intermittent supply mechanism 50 to the supply stop state.

After switching the intermittent supply mechanism 50 to the supply state and before switching the damming mechanism 40 to the open state, the chip component C among the dammed components to be separated climbs the second inclined surface 21s. It is the time given to separate. This predetermined time is preferably, for example, 5 seconds or more and 10 seconds or less. If the time is less than 5 seconds, the separation of the chip component C may become insufficient, and if the time exceeds 10 seconds, the chip component C can be sufficiently separated, but the processing time is wasted. For a reason. The predetermined time is more preferably 6 seconds or longer within the range of 5 seconds or longer and 10 seconds or shorter.

The chip component C separated by the first vibration isolator 10, that is, the component to be separated climbing the first inclined surface 11s drops from the upward end 11a onto the third inclined surface 31s of the third vibration isolator 30. FIG. The chip component C dropped onto the third inclined surface 31s climbs up the vibrating third inclined surface 31s, drops from the upward end 31a onto the first recovery tray 61 of the rectangular parallelepiped component recovery section 60, and is recovered. Here, when there is a medium M among the parts to be separated that have fallen on the third inclined surface 31s, the medium M rolls down the third inclined surface 31s and is ejected from the spherical component recovery part 65 from the downward end 31b. dropped to the third collection tray 67 and collected.

Due to the above operation, in the vibration isolation device 1, the components to be separated, which are mixed components of the plurality of chip components C and the plurality of media M supplied to the component supply unit 5, are separated from the plurality of chip components C in the first recovery tray. 61, and a plurality of media M are collected on a second collection tray 66 or a third collection tray 67 and separated.

According to the vibration isolation device 1 according to the present embodiment described above, the following effects are achieved.
The vibration isolation device 1 according to the present embodiment has a component supply section 5 that supplies components to be separated, and a vibrating first inclined surface 11s. It has a first vibration isolating part 10 that separates a part to be separated ascending the surface 11s and a part to be separated descending the first inclined surface 11s, and a second inclined surface 21s that vibrates. The parts to be separated that are placed below the downward end 11b of the first inclined surface 11s and dropped from the downward end 11a of the first inclined surface 11s are divided into the parts to be separated that climb the second inclined surface 21s and the second inclined surface 11s. A second vibration separating portion 20 that separates the part to be separated descending from two inclined surfaces 21s, and a third inclined surface 31s that vibrates. 11a and dropped from the end 11a on the upward side of the first inclined surface 11s, the separated components ascending the third inclined surface 31s and the separated components descending the third inclined surface 31s. a third vibration separating portion 30, a damming mechanism 40, and a control portion 70, and the damming mechanism 40 is provided with at least one of the first inclined surface 11s, the second inclined surface 21s and the third inclined surface 31s. On any one of the inclined planes, either a dammed state in which the part to be separated that moves to the lower side of the inclined plane is dammed, or an open state in which the dammed state is released and the part to be separated is allowed to move to the lower side of the inclined plane. In one state, the control unit 70 selectively switches the damming mechanism 40 between the damming state and the open state. In one embodiment, the damming mechanism 40 is specifically provided in the second vibration isolation section 20 .

As a result, the component to be separated that has fallen onto the second inclined surface 21s is blocked by the damming mechanism 40 from descending the second inclined surface 21s. It becomes possible to climb the second inclined surface 21s without being caught. Therefore, highly accurate separation can be performed in the second vibration isolating section 20 .

The vibration isolation device 1 according to the present embodiment further includes an intermittent supply mechanism 50 that intermittently supplies the part to be separated to the second inclined surface 21s on which the damming mechanism 40 acts. to either a supply state in which the parts to be separated are supplied or a supply stop state in which the supply of the parts to be separated is stopped.

As a result, the part to be separated can be supplied to the second vibration isolation section 20 provided with the damming mechanism 40 at an appropriate timing, so that the separation can be performed with higher precision.

In the vibration isolation device 1 according to the present embodiment, the control unit 70 switches the intermittent supply mechanism 50 from the supply stop state to the supply state while the damming mechanism 40 is controlled to be in the damming state. , the damming mechanism 40 is switched to the open state after a predetermined time has elapsed.

As a result, after the component to be separated is supplied to the second inclined surface 21s, the component to be separated is prevented from descending the second inclined surface 21s for a predetermined time, thereby preventing the chip component C from going up the second inclined surface 21s. However, it is possible to more effectively prevent the problem of being caught in the media M descending the second inclined surface 21s and descending the second inclined surface 21s and not being separated.

In the vibration isolation device 1 of this embodiment, the predetermined time from switching the intermittent supply mechanism 50 to the supply state to switching the damming mechanism 40 to the open state is 6 seconds or longer.

As a result, the time required for the chip component C to climb the second inclined surface 21s and be separated from the component to be separated that is blocked by the damming mechanism 40 is sufficient. As a result, the problem that a small amount of chip components C trying to climb the second inclined surface 21s are caught in a large amount of media M descending the second inclined surface 21s and go down the second inclined surface 21s is not separated. can be effectively prevented.

In many cases, C is mixed and separation is relatively difficult. Therefore, if the damming mechanism 40 acts on the second inclined surface 21s as in the present embodiment, separation can be performed with high precision even on the second inclined surface 21s, which tends to be difficult to separate.

In the vibration isolation device 1 of the present embodiment, the upward end 21a of the second inclined surface 21s and the upward end 31a of the third inclined surface 31s are arranged to face each other. , a chip component C as a rectangular parallelepiped component to be separated, and a mixed component of a medium M as a spherical component to be separated. , the rectangular parallelepiped component recovery unit 60 is located below the upward end 21a of the second inclined surface 21s and below the upward end 31a of the third inclined surface 31s, and is located above the second inclined surface 21s. It is arranged at a position to receive both the chip components C falling from the side end 21a and the upward end 31a of the third inclined surface 31s.

As a result, a large amount of chip components C separated from the components to be separated can be collectively collected in one rectangular parallelepiped component collection unit 60 .

The vibration isolating device 1 of the present embodiment includes a first inclination angle adjusting section 13 that adjusts the inclination angle of the first inclined surface 11s, a second inclination angle adjustment section 23 that adjusts the inclination angle of the second inclined surface 21s, and a third tilt angle adjuster 33 that adjusts the tilt angle of the third tilt surface 31s.

In the first inclined surface 11s, the second inclined surface 21s, and the third inclined surface 31s, in addition to the size, shape, weight, etc. of the parts to be separated, various factors such as the existence ratio of the parts to be separated can be applied. Depending on the variables associated with the part, there may be an appropriate tilt angle that facilitates separation of the part to be separated. Therefore, if the inclination angles of the first inclined surface 11s, the second inclined surface 21s, and the third inclined surface 31s can be adjusted, the appropriate inclination angles can be easily set. Since the present embodiment includes the first tilt angle adjusting portion 13, the second tilt angle adjusting portion 23, and the third tilt angle adjusting portion 33, the first tilting surface 11s, the second tilting surface 21s, and the third tilting surface 31s can be easily adjusted to an appropriate inclination angle that facilitates separation of the parts to be separated, and as a result, the separation accuracy of the first inclined surface 11s, the second inclined surface 21s and the third inclined surface 31s can be enhanced. can.

The state, the vibration state of the second vibration isolation section 20, and the vibration state of the third vibration isolation section 30 are controlled.
