[0013]

In the adhering matter removing device according to the present invention having the above-mentioned structure, the air pulsation wave is transmitted to the particulate matter supplied from the supply port onto the perforated plate. The particulate matter can be vibrated in the vertical direction on the perforated plate, whereby the deposit can be removed from the particulate matter. Then, by utilizing the vibrating action of the particulate matter, the particulate matter is transferred to the discharge port side while rolling on the perforated plate, and the particulate matter from which the attached matter is removed can be taken out of the housing case. Therefore, if the granular materials are sequentially supplied from the supply port onto the perforated plate, the adhering matter removing process can be continuously performed while transferring the continuously supplied granular materials on the perforated plate.

Further, when the granular material rolls and is transported on the perforated plate, the surface of the granular material comes into contact with a large number of convex portions for removing the adhered substances of the perforated plate. Therefore, even if the particulate matter cannot be separated and removed only by vertical vibration,
By contact with the convex portion for removing the adhered matter, the adhered matter is forcibly peeled off from the granular matter and properly removed.

Further, if the particulate matter transported on the perforated plate sequentially contacts the convex portion for removing the deposit, the transport speed of the particulate matter becomes low due to the resistance of the convex portion for removing the deposit. . Therefore, the time when the granular material stays on the perforated plate can be lengthened as much as the transfer speed becomes slower.
It is possible to extend the time for which the particulate matter receives the air pulsation wave, and to more thoroughly remove the attached matter.

In the deposit removing device according to the second aspect of the present invention, a negative pressure air pulsation wave is transmitted from the air pulsation wave generator to vibrate the particulate matter on the porous plate. Not only can the adhered matter be removed from the particulate matter, but also the adhered matter removed from the granular matter can be sucked from the upper opening of the housing case by the negative pressure generated by the air pulsation wave generator and discharged to the outside. be able to. Therefore, it is possible to appropriately prevent the adhered matter removed from the granular material from re-adhering to the granular material without leaving the adhered material in the housing case.

In the deposit removing device according to the third aspect of the present invention, the air pulsating wave generator sends a positive pressure air pulsating wave from below the perforated plate, so that the particulate matter is placed on the perforated plate. While it can be vibrated by, the adhered matter removed from the particulate matter is sucked by the air suction source from the upper opening of the housing case and discharged to the outside of the housing case. Therefore, like the second aspect, the deposits do not unreasonably remain in the housing case.

In the deposit removing device according to the fifth aspect of the present invention, since the protrusion for removing deposits provided on the surface of the porous plate is composed of a brush, it rolls on the porous plate. The surface of the transferred granular material can be brushed with a large number of hairs, and the adhered material can be removed finely. Further, the contact between the highly flexible brush and the granular material prevents the granular material from being easily broken or damaged.

In the deposit removing device according to the sixth aspect of the present invention, although the protrusion for removing deposits is not formed, when the particulates are rotatably transferred on the perforated plate, the particulates are removed. Since the object comes into contact with a large number of bristles on the brush surface and is brushed, the adhered matter is also removed finely,
It is possible to properly peel off and remove the deposits that could not be removed only by vertical vibration. Further, since the brush surface is highly flexible, the granular material transported on the brush surface is not easily damaged.

[First embodiment (corresponding to claims 1, 2, 4, 7, 8, 9, 11)]

FIG. 1 is an explanatory diagram showing an adhering matter removing device A according to a first embodiment of the present invention. This adhering matter removing device A is used for removing adhering matters such as lubricants and other dust adhering to tablets m, which are an example of granular materials, and is a housing case formed in a predetermined hollow container shape. 1, a plurality of perforated plates 2 (2a to 2c) provided in the housing case 1,
And an air pulsation wave generator B for generating a negative pressure air pulsation wave.

Of the above, each porous plate 2 (2a-2c)
2, is provided with a large number of vent holes 20 ... Penetrating in the vertical direction, and the surface portion (upper surface portion) thereof is formed in a corrugated uneven shape. That is, the large number of convex portions 21 on the surface of the corrugated porous plate 2 correspond to the convex portions 21 for removing the deposit according to the present invention. The pitch P between the convex portions 21, 21 is set to be smaller than the diameter D of the tablet m, and is designed so as not to hinder the transfer of the tablet m described later.

In FIG. 1, the perforated plates 2 are supported by a plurality of support rods 7 ... The tablet m supplied from the tablet supply port 9 to which 8 is connected is sequentially transferred to the perforated plates 2a, 2b, 2c, and can be guided to be transferred to the discharge port 10. These perforated plates 2a to 2c are provided so that the setting angle (inclination angle) of each of them can be arbitrarily adjusted by changing the mounting position of the supporting rods 7 ...

The air pulsating wave generator B intermittently sucks the air in the housing case 1 through the upper opening 1b of the housing case 1 and imparts negative pressure air vibrations into the housing case 1. The housing case 1 does not need to have a completely closed structure in order to generate air vibrations, and an opening 1c for introducing an appropriate amount of air is appropriately provided on the bottom side of the housing case 1.

As a concrete example of the air pulsating wave generator B,
For example, a blower 5 and a pulsation imparting device 6 as shown in FIG. 3A are used. The pulsation imparting device 6 includes a valve body 6 which is rotated by a motor M in a cylindrical casing 63 having two ports 62a and 62b.
4 is provided. In this air pulsating wave generator B, when the valve body 64 is in the rotation angle state shown in FIG. 3A while the air in the casing 63 is continuously exhausted by the blower 5 connected to the port 62a, Intake is performed at the port 62b. On the other hand, when the valve element 64 has the rotation angle shown by the solid line in FIG.
Since the valve body 64 blocks between the ports 62a and 62b, the intake at the port 62b is stopped.

In this air pulsation wave generator B, the valve body 64
Is continuously rotated, and the intake and the stop thereof at the port 62b are alternately repeated, whereby a negative pressure air pulsation wave having a pressure waveform as shown in FIG. 4A is transmitted from the port 62b. . As this air pulsation wave, for example, 10H
A low frequency band of about z is adopted. However, the specific configuration of the air pulsation wave generator B applied in the present invention is not limited to the above. The negative pressure air pulsation wave is not limited to the waveform shown in FIG. 4A, and may be a pressure air pulsation wave as shown in FIG. 4B, for example. Further, as shown in FIG. 4C, a pressure waveform may be such that a part of the air pressure (shown by S in the same figure) turns into positive pressure in a constant cycle.

The air pulsating wave generator B is connected to the upper opening 1b of the housing case 1 through a pipe section (waveguide) 12 and is located above the uppermost perforated plate 2a. It is provided so that negative pressure air pulsation waves can be transmitted to 2a to 2c. A dust collecting filter 40 is provided at an intermediate position of the pipe portion 12.

Next, an example of use and operation of the deposit removing device A having the above-mentioned structure will be described. First, the air pulsation wave generator B is operated to send a negative pressure air pulsation wave from the upper opening 1b of the housing case 1 to the perforated plates 2a to 2c. In such a state, when an appropriate amount of the tablets m loaded in the loading device 8 are supplied from the supply port 9 onto the perforated plate 2a and placed, these tablets m are periodically generated on the upper side thereof. Up and down vibrations are repeated in which the negative pressure sucks up and then drops.

Then, when the tablet m is repeatedly vibrated in the vertical direction in this manner, the tablet m rolls on the perforated plate 2a. Naturally, it moves to the front downward direction on the low position side,
It will be transferred by rolling in the direction of arrow a. Even when the perforated plate 2a is in the horizontal state, the tablets m are supplied to the supply port 9
Since the rolling to the side provided with is blocked by the supply pressure of the tablet m, it is also possible to roll and transfer in the direction of the arrow a.

When the tablet m is forcibly vibrated in the vertical direction, this causes a peeling action of the deposit adhered to the surface of the tablet m. Then, when the tablet m rolls on the perforated plate 2a which is formed in an uneven shape, the surface of the tablet m sequentially contacts the convex portion 21 for removing the adhering substance as shown in FIG. Therefore, even if the attached matter cannot be removed only by the vertical vibration due to the air pulsation wave, the attached matter is forcibly separated from the surface of the tablet m by the physical contact between the tablet m and the convex portion 21, Can be removed.

Further, since the convex portion 21 for removing the adhered substance also acts as a resistance force when the tablet m is transferred, the transfer speed of the tablet m on the perforated plate 2a becomes low. Therefore, even when the total length of the perforated plate 2a is shortened, the time during which the tablet m stays on the perforated plate 2a can be lengthened, and the prolonged adherence time also promotes the removal of the deposits. You can The deposits thus peeled off are sucked into the pipe portion 12 through the upper opening 1b that transmits a negative pressure air pulsation wave, and are collected by the dust collecting filter 40. There is no risk that the peeled deposits will reattach to the tablet m.

As described above, the tablets m tumbled and transferred while removing the deposits are successively transferred to the lower porous plates 2b and 2c after the transfer on the porous plate 2a is completed. Even at the position of each of the perforated plates 2b, 2c, the deposits are sequentially removed by the vertical vibration action and the contact action with the protrusion 21 for removing the deposits while being rolled and transferred as described above. It is discharged from the discharge port 10 after the adhered substances are more thoroughly removed. If the tablets m are processed while being sequentially transferred to the discharge port 10 side in this way, there is no problem even if the tablets m are continuously supplied onto the porous plate 2a. Therefore, a large amount of tablets m can be continuously and efficiently processed. A container for accommodating the tablets m from which the adhered substances have been removed, a conveyor 14 for conveying the tablets m to the next step, or the like may be provided below the discharge port 10.

[Second Embodiment (corresponding to Claims 3 and 10)] FIG. 6 is a schematic diagram showing a deposit removing device Aa according to a second embodiment of the present invention.
FIG. 4 is an explanatory view showing (the same portions as those in the first embodiment are designated by the same reference numerals). Unlike the deposit removing device A shown in the first embodiment, the deposit removing device Aa continuously exhausts air from the upper opening 1b of the housing case 1A by a blower 3 as an example of an air suction source. With
The positive pressure air pulsation wave generated by the air pulsation wave generator Ba is transmitted from the lower opening 1a of the housing case 1A into the housing case 1A.

Here, as the air pulsating wave generator Ba, for example, as shown in FIG. 7, a device including a pulsation imparting device 6A and a blower 5A can be applied. The pulsation imparting device 6A has a basic structure in common with the pulsation imparting device 6 for generating a negative pressure air pulsation wave shown in FIG. 3, and has a cylindrical casing 63A having two ports 62c and 62d. In addition, a valve body 64A driven and rotated by the motor M is provided. The one port 62c side is connected to the exhaust side of the blower 5A.

In such a construction, when the valve body 64A is in the position shown by the solid line in the figure while the compressed air is continuously supplied from the blower 5A into the casing 63A, the compressed air is discharged from the port 62d. Ejection takes place.
On the other hand, when the valve body 64A reaches the position shown by the alternate long and short dash line in the figure, the discharge of the compressed air from the port 62d is stopped. Therefore, when the valve body 64A continuously rotates,
The compressed air is repeatedly discharged and stopped at the port 62d, and as a result, a positive pressure air pulsation wave having a waveform as shown in FIG. 8A is generated. However, the present invention is not limited to this, and for example, as the waveform of the positive pressure air pulsation wave, an air pulsation wave having a waveform as shown in FIG. 8B may be generated.

In the adhered matter removing device Aa shown in FIG. 6, the positive pressure air pulsation wave generated by the air pulsation wave generator Ba can be sent upward from a position below the porous plate 2. Therefore, the tablets m supplied and placed on the porous plate 2a can be vertically vibrated by the air pulsation wave. Then, as in the case of the first embodiment, the tablets m are sequentially rolled and transferred to the discharge port 10 side by this vertical vibration, and at the transfer stage, the efficiency of using the convex portion 21 for removing the deposit is improved. Good removal of deposits is possible. Further, the deposits removed from the tablets m are sucked from the upper opening 1b by the suction pressure of the blower 3 to be collected by the dust collecting filter 4
Since it is collected on the 0 side, it does not cause reattachment of deposits. Therefore, the same effect as that of the first embodiment can be obtained by the deposit removing device Aa of the second embodiment.

It may be configured as a convex portion (corresponding to claims 5 and 12). According to this structure, the adhering matter of the tablet m can be finely separated by the brushing action of the brush 30, and the adhering matter removing action can be enhanced. In addition, since a large impact force is not applied to the tablet m when it comes into contact with the tablet m, the tablet m
It is possible to obtain an advantage that damage of the can be appropriately prevented.

In FIG. 11, brushes 30a are provided at regular intervals on the surface of a perforated plate 2C having a corrugated surface, and the present invention may have such a configuration.

FIG. 12 shows a structure in which a brush surface 32 having a large number of bristles planted in an upward state is provided on the entire surface area or substantially the entire surface portion of the flat porous plate 2D (corresponding to claims 6 and 13). In addition, the brush surface 3 is provided at the position where the vent hole 20 is opened.
It is not necessary to provide 2. In such a configuration, the brush surface 32
A large number of hairs individually contact the tablet m, exhibiting the action of peeling and removing the adhering matter, and also excellent adhering matter can be removed. Also, this brush surface 32 is highly flexible,
Moreover, since the flat surface is sufficient, it is possible to appropriately prevent damage to the tablet m.

Further, in the present invention, for example, when three perforated plates 2a to 2c are provided on the upper and lower sides as shown in FIG. 1, for removing adhered substances on each surface of all the perforated plates 2a to 2c. It is not necessary to provide the convex portion 21 of the convex portion 2 and only one of the three porous plates 2a to 2c has the convex portion 2.
The configuration in which 1 is provided may be used. Further, in the present invention, it is not essential to use a plurality of perforated plates, and for example, one perforated plate may be used. In addition, the specific type of the particulate matter that is the object of adhered matter removal is not limited to tablets, and synthetic resin pellets, granular foods, grains, metals, etc.
It is possible to apply to various granules.
