  The attaching / detaching means 42 is, for example, a vacuum adsorber including one or a plurality of suction cups 45 and an intake pipe (not shown) connected to the suction cups 45. The attaching / detaching means 42 attracts (adheres) the vibrator 31 to the outer surface of the cone portion 22 of the container 20 at an operation position described later. The suction cup 45 adsorbs the vibrator 31 by depressurizing the inside (adsorption surface) of the recess through the intake pipe. For example, a pressure reducing means such as an air ejector or a vacuum pump (not shown) may be connected to the intake pipe.

  The attaching / detaching means 42 is not limited to a vacuum suction device such as a suction cup, and, for example, if the container 20 is formed of a steel material or the like that can attract a magnet, an electromagnetic suction device using an electromagnet or the like is adopted. You can also.

The transporter 32 includes an extendable part 51 and an engaging part 52.
The expansion / contraction part 51 consists of an air cylinder which expands and contracts by air injection | pouring and discharge | emission, for example. For example, the expansion / contraction part 51 is inclined and fixed to the vibration device mounting part 14 so as to expand and contract along a direction substantially perpendicular to one surface of the cone part 22 of the container 20 placed on the gantry 11. Has been.

  In addition to the air cylinder, the expansion / contraction part 51 may be expanded / contracted by an electrical mechanism such as a hydraulic cylinder that expands / contracts by hydraulic pressure, or a motor and gear.

  The engaging portion 52 has a substantially U-shape comprising two flat plates 52a and 52b (see FIG. 3) arranged in parallel to each other and a connecting plate 52c (see FIG. 3) that connects one end of these flat plates. And is joined to the tip of the stretchable part 51 at the center of the connecting plate 52c. Such an engaging portion 52 is detachably engaged with the engaging end portion 43 of the vibrator 31 at the tip portions of the two flat plates 52a and 52b, and supports the vibrator 31.

One end 33 a of the suspension member 33 is engaged with the tip end portion of the refracted member extending to the upper portion of the conveyor 32 in the vibration device mounting portion 14. The other end 33 b is engaged with the vibrator 31. As a result, the vibrator 31 is suspended in a swingable manner by the vibration device mounting portion 14 via the suspension member 33.

  One end 33 a of the suspension member 33 is positioned below the lower portion of the cylindrical portion 21 of the container 20 along the vertical direction, and is positioned above the position range facing the cone portion 22 of the container 20. It is preferable to form so as to.

  In addition to the metal wire, the hanging member 33 can freely swing the vibrator 31 such as a metal chain, a synthetic fiber rope, and a metal rod whose end is rotatably fixed. There is no particular limitation as long as it can be hung and can prevent the vibrator 31 from falling.

3, 4, and 5 are perspective views showing the state of the vibration device 12.
In the vibration device 12 of the present invention configured as described above, the vibration device 31 is supported by the operating position (see FIG. 3) adsorbed on the outer surface of the cone portion 22 of the container 20 by the attaching / detaching means 42, and the transport device 32. It is possible to move between a standby position (see FIG. 4) separated from the container 20.
The vibrator 31 moves obliquely upward when moving from the standby position to the operating position, and moves diagonally downward when moving from the operating position to the standby position.

  Further, the transporter 32 moves between an extended position (see FIG. 3) where the air cylinder protrudes and a retracted position where the air cylinder retracts. Among these, the extension position is a position where the expansion / contraction part 51 extends to a position where the attaching / detaching means 42 of the vibrator 31 contacts the outer surface of the container 20. In the retracted position, when the vibrator 31 is engaged with the engaging portion 52 (see FIG. 4), the vibrator 31 is attracted to the container 20 and the vibrator 31 and the transport machine 32 are engaged. Is released and only the transporter 32 moves to the retracted position (see FIG. 5).

(Vibration application method)
The operation of the vibration device of the present invention having the above configuration and a method of applying vibration to a container using the vibration device of the present invention will be described.
FIG. 6 is a flowchart showing stepwise the vibration application method of the present invention.
When discharging a predetermined amount of the granular material M placed in the container 20 mounted on the gantry 11 of the container discharge device 10 and connected to the chute 13, the vibration device 12 is operated. First, the expansion / contraction part 51 of the conveyance machine 32 (refer FIG. 4) in the retraction position which supported the vibrator 31 in a standby position is extended (1st movement process S1).

  By the first moving step S1, as shown in FIG. 3, the telescopic part 51 of the transporter 32 moves to the extended position. When the extendable part 51 moves to the extended position, one or more suction cups 45 that are the attaching / detaching means 42 of the vibrator 31 are pressed against the outer surface of the cone part 22 of the container 20. At the same time, the inside of the concave portion of the suction cup 45 is depressurized through the intake pipe, whereby the vibrator 31 is adsorbed (adhered) to the outer surface of the cone portion 22 of the container 20 (adsorption step S2).

  Next, as shown in FIG. 5, the engagement between the engagement end portion 43 of the vibration device 31 and the engagement portion 52 of the transport device 32 is released in a state where the vibration device 31 is attracted to the container 20. The part 51 moves to the retracted position (engagement release step S3).

And air is supplied to the vibration part 41 which consists of an air vibrator which comprises the vibrator 31, and the vibrator 31 vibrates. As a result, vibration is applied (propagated) to the container 20 via the attaching / detaching means 42 (vibrating step S4).
At the same time, the shaft member 28 supported by the shaft support portion 27 of the top surface portion 24 of the container 20 is pulled upward, and the cone valve 25 moves upward. As a result, the outlet 23 at the bottom of the container 20 is opened, and the granular material M accommodated inside the container 20 is discharged to the outside through the chute 13 (discharge step S5).

  In such a discharge process S5, by performing a vibration process S4 in which vibration is applied to the container 20 by the vibrator 31, for example, even a fine powder having a small particle diameter or a granular material having a large variation in particle diameter can be used as a container. The lump is broken by the vibration in 20 and is smoothly guided to the discharge port 23 without being deposited on the cone portion 22 of the container 20. Therefore, the predetermined amount of the granular material M accommodated in the container 20 can be discharged.

  On the other hand, after transporting the vibrator 31 toward the container 20 in the first movement step S1, the transporter 32 releases the engagement between the vibrator 31 and the transporter 32 in the disengagement step S3, and the retracted position. Move to. Thereby, in vibration process S4, since the engagement with the vibrator 31 and the conveyance machine 32 is disconnected, the vibration generated in the vibration machine 31 propagates to the vibration device mounting portion 14 via the conveyance machine 32. Can be suppressed. As a result, the vibration propagates to the screwing portions of the vibration device mounting portion 14 which is a pedestal for supporting the vibrator 31 and the members constituting the transport machine 32 and the screws are loosened by the vibration, or the joint portion is worn by the vibration. It is possible to prevent deterioration or breakage due to vibration of the vibration device mounting portion 14 or the conveyor 32.

  The vibrator 31 is connected to the vibration device mounting portion 14 that forms the gantry 11 through the suspension member 33 in the vibration step S4. The suspension member 33 is made of a flexible material such as a metal wire. Therefore, the vibration propagating from the vibrator 31 to the gantry 11 through the suspension member 33 is slight, and the vibration that affects the joint portion of the gantry 11 is not propagated.

Next, when a predetermined amount of the granular material M stored in the container 20 is discharged from the discharge port 23, the shaft member 28 is lowered and the cone valve 25 is moved downward to close the discharge port 23 of the container 20. .
Then, as shown in FIG. 3, the telescopic part 51 of the transport machine 32 in the retracted position is moved to the extended position, and the engaging end 43 of the vibrator 31 and the engaging part 52 of the transport machine 32 are engaged again. (Engagement step S6).

Next, the decompression inside the recesses of the plurality of suction cups 45 which are the attaching / detaching means 42 of the vibrator 31 is stopped, and the adsorption (adhesion) of the vibrator 31 to the container 20 is released (adsorption release step S7).
And as shown in FIG. 4, the expansion-contraction part 51 of the conveying machine 32 which supported the vibrator 31 is moved to a retracted position. Thereby, the vibrator 31 moves to a standby position separated from the outer surface of the container 20 (second movement step S7).
Through the above steps, a predetermined amount of the granular material M accommodated in one container 20 can be smoothly discharged in a short time.

  As described above, according to the vibration device and the vibration application method of the present invention, when the container 31 is vibrated by the vibrator 31 in order to smoothly discharge the granular material M, it is conveyed from the vibrator 31. By separating the machine 32, it is possible to suppress the propagation of vibration to the vibration device mounting portion 14 and the transport device 32, and to prevent the vibration device mounting portion 14 and the transport device 32 from being deteriorated or damaged by vibration. It becomes possible.

  Moreover, if an air vibrator is used for the vibrator 31 constituting the vibration device 12 and an air cylinder is used as the transport device 32 for moving the vibrator 31 between the operating position and the standby position, the vibration device 12 is compressed air. Can only be driven. Thereby, it is not necessary to draw in another power source such as electricity or hydraulic pressure in addition to a compressor that is general as factory equipment, and the vibration device 12 can be installed at low cost.

  In addition, the vibrator 31 is suspended from the container 20 for some reason during the operation of the vibrator 31 that has been disengaged from the conveyor 32 by suspending the vibrator 31 from the vibration device mounting portion 14 by the suspension member 33. Even if 31 is detached, the vibrator 31 does not fall to the floor surface, and damage to the vibrator 31 can be prevented.

  Further, by making the vibrator 31 and the conveyor 32 detachable, the vibrator 31 can be rotated with respect to the outer surface of the container 20, and thereby the outer surface of the container 20 that can suck the vibrator 31. The inclination angle range of is widened. That is, the vibrator 31 can be reliably brought into close contact with a plurality of types of containers 20 whose outer surfaces (cone portions) have different inclination angles depending on the type of the granular material M to be accommodated.

In the above-described embodiment, the example in which the vibration step S4 is performed simultaneously with the start of the discharge step S5 and is ended with the completion of the discharge step S5 is shown. However, the timing of the start and end of the vibration step S4 is this. It is not limited to.
For example, after the discharge step S5 is started, the vibration step S4 is started when the granular material M is discharged from the container 20 to some extent, or after the discharge step S5 for naturally flowing the granular material M from the container 20 is completed, the vibration step S4 can be started and the granular material M adhering and depositing inside the container 20 can be discharged. Further, prior to the start of the discharge step S5, the vibration step S4 can be started.

  In the vibration application method of the present invention, the operation of the vibrator 31, the transport machine 32, and the cone valve 25 in each step is operated according to a program in the control unit, thereby placing the container 20 on the gantry 11, A series of operations from opening of the cone valve 25, operation of the vibration device 12, closing of the cone valve 25, and movement of the container 20 can be automated.

  As mentioned above, although embodiment of this invention was described, such embodiment is shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof, as long as they are included in the scope and gist of the invention.
