It is about.

[0002]

2. Description of the Related Art An article supply apparatus ("parts supply apparatus") for aligning and sending out mechanical parts and various relatively small articles.
One of the methods is to rotate a disk having an inclined posture in a rotating ball. For example, Japanese Patent Application Laid-Open No. 8-225142 and Japanese Patent Publication No. 1-514
No. 03 publication. FIG. 10 shows a schematic structure of the rotating disk type article supply apparatus.

In FIG. 1, reference numeral 151 denotes a horizontal disk-shaped mechanism base. An insertion hole 153 is formed in the center of the base, and a ball bearing 155 is attached so as to surround the insertion hole 153. Reference numeral 157 denotes a rotating ball (which may be referred to as a “turning track” or the like), a main part 159 having a circular deep dish shape, a component transfer flange 161 projecting outward from an upper opening thereof, and a bottom wall of the main part 159. 159a comprises a cylindrical supported portion 163 protruding downward from the center hole, and the supported portion 163 is rotatably supported by the ball bearing 155.

A rotating ball driving mechanism 165 having a motor and a rotating disk driving mechanism 167 are disposed below the mechanism base 151. The rotating ball 157 controls the driving force of the rotating ball driving mechanism 165 by an endless belt or gear. It is rotated by being transmitted. Rotating disk drive mechanism 167
The rotating shaft 169 extends to the inside of the main portion 159 through the supported portion 163 of the rotating ball 157 in a posture inclined with respect to the vertical direction, and a rotating disk 171 is attached to the tip of the rotating shaft 169. . The highest part of the rotation trajectory of the outer peripheral edge of the rotating disk 171 is the rotating ball 157.
Is located on the same plane as the component transfer flange 161 or slightly higher. The rotating disk 171 is rotated in the same direction as the rotating direction of the rotating ball 157.

[0006]

This type of article supply apparatus has been widely used today for supplying various articles, and is not limited to supplying parts to a machine assembling process but also to processing of processed foods and the like. It is also used as a supply device for the process and packaging process. When the supplied article is such as a rice cracker or a deep-fried confectionery that powdery garbage is liable to be generated, the garbage falls from the gap between the inner peripheral surface of the rotating ball 157 and the rotating disk 171 and rotates. Since it accumulates on the bottom wall 159a of the 157, there is a problem that this prevents smooth rotation of the rotating disk 171 and causes unsanitary condition. Further, dust spilled outward from the component transfer flange 161 accumulates on the mechanism base 151.

Therefore, at the site where such articles are supplied, the inside of the rotating ball 157 and the upper surface of the mechanism base 151 are cleaned as needed. This is a very troublesome operation of removing the plate 171 from the disk mounting disk and inserting a broom, a brush or the like into a narrow place, so that the operation must be stopped for a considerably long time, and the operation efficiency of the line is reduced. There was a problem.

Further, in order to completely remove dust from food or the like, the entire inside of the rotating ball 157 and the mechanism base 15 are removed.
Although there is no other way than to wash the ball 1, since the supported portion 163 of the rotating ball 157 is attached so as to hold the inner race of the ball bearing 155 from above and below, it is practically necessary to frequently remove the rotating ball 157 and wash with water. Impossible. Therefore, washing the rotating ball 157 with water
Without stopping, this was performed while being attached to the mechanism base 151. However, if water is applied to the inside of the rotating ball 157 vigorously, the water passes through the supported portion 163 and falls on the rotating ball driving mechanism 165 or the rotating disk driving mechanism 167. It is required to take time.

[0009] Further, the washing of the mechanism base 151 with water is also performed.
Care must be taken to prevent water from splashing on the ball bearings 157. In addition, when cleaning the upper surface of the mechanism base 151, the surrounding wall 173 has to be removed each time, and there is a problem that this removing operation takes time.

The present invention has been made in view of the above-mentioned conventional problems, and is a rotating disk type article supply apparatus capable of automatically removing dust falling on the inside of a rotating ball or on a mechanism base. The purpose is to provide. Another object of the present invention is to provide a rotating disk-type article supply device capable of easily washing a rotating ball and a mechanism base with water.

[0011]

In order to achieve this object, an article supply apparatus according to the present invention comprises a rotating ball having a component transfer flange projecting outward from an upper opening, and an inclined posture disposed in the rotating ball. A rotating disk, a rotating ball supporting mechanism rotatably supporting the rotating ball, a rotating ball driving mechanism for rotating the rotating ball, a rotating disk driving mechanism for rotating the rotating disk, and a bottom wall of the rotating ball. A dust removing mechanism provided in a space between the rotating disc and a dust removing hole is formed in a bottom wall of the rotating ball, and the dust removing mechanism removes a squeegee provided on a rotation locus of the dust removing hole. The squeegee causes the refuse dropped on the bottom wall of the rotating ball to fall from the trash drop hole while being sequentially collected. Further, the invention of claim 2
The rotating disk-type article supply device according to claim 1,
A plurality of squeegees are provided, and at least two
Are provided in a positional relationship of substantially U-shape when viewed from above, and the trash falling on the bottom wall of the rotating ball is sequentially gathered outward and inward by at least two squeegees having the U-shape. It is designed to fall from the trash drop hole.

Therefore, dust that has fallen inside the rotating ball is always gathered by the squeegee and dropped from the dust drop hole, so that dust hardly accumulates inside the rotating ball, and the cleaning time is greatly reduced. Can be omitted.
In particular, in the present invention, the squeegee does not merely block the trash, but falls from the trash drop hole in a state of flowing while being gathered to the outside and the inside by the two squeegees having a C-shape, so that the trash is collected. Not only can it be collected to every corner, but there is no danger that the collected garbage will compact.

[0013] The directions of the two squeegees forming a C shape are
If the shape of the letter "C" is open toward the center of the rotating ball, the dust is first moved outward and hits the peripheral wall of the rotating ball, and the next movement is guided. Easy to control. However, the directions of the two squeegees forming a U-shape are not limited to this, and depending on the size of the space and the relationship with the surrounding mechanisms, the shape of the squeegee may be a direction closed toward the center of the rotating ball. Is also good.

According to a third aspect of the present invention, there is provided a rotating ball having a component transfer flange projecting outward from an upper opening, a rotating disk disposed in an inclined position in the rotating ball, and the rotating ball rotatably supported.

With
A dust removing hole is formed in the bottom wall of the rotating ball, and a dust removing mechanism is provided with a squeegee provided on a rotation locus of the dust removing hole and a fluid injection nozzle provided near the squeegee and oriented in the rotation locus. The dust that has fallen on the bottom wall of the rotating ball is dropped from the dust drop hole by at least the fluid ejected from the fluid ejection nozzle in a state of being gathered by the squeegee.

Therefore, the dust that has fallen inside the rotating ball is dropped from the dust drop hole while being gathered by the squeegee, or even if the dust is bridged and caught by the dust drop hole, the fluid jet nozzle ejects the dust. In any case, dust is hardly accumulated inside the rotating ball, and the trouble of cleaning can be largely saved. In particular, in the present invention,
Since the dust is forcibly blown off by at least the fluid ejected from the fluid ejection nozzle, even highly viscous dust can be more reliably removed. The type of the fluid to be ejected may be any type that can blow off air, water, and other dust, and it is preferable to select the most appropriate type according to the size and properties of the dust coming out of the supply article.

A rotating ball support mechanism, a mechanism base provided with the rotating ball support mechanism, a rotating ball driving mechanism for rotating the rotating ball, and a rotating disk driving mechanism for rotating the rotating disk, are provided on the bottom wall of the rotating ball. Is a rotary disk type article supply device provided with a dust drop hole for removing dust dropped here, wherein a wiper in contact with an upper surface of a mechanism base is attached to a rotary ball.

Accordingly, since the wiper always rotates integrally with the rotating ball, the wiper constantly sweeps and cleans the upper surface of the mechanism base and collects the debris dropped there while the apparatus is operated. The dust collected by the wiper may be removed, for example, by providing a dust drop hole in the mechanism base, or by removing the dust below the mechanism base by inclining the upper surface of the mechanism base downward.

According to a fifth aspect of the present invention, there is provided a rotating ball having a component transfer flange projecting outward from an upper opening, a rotating disk disposed in an inclined position in the rotating ball, and the rotating ball rotatably supported. A rotating ball support mechanism, a rotating ball driving mechanism for rotating the rotating ball, and a rotating disk type article supply device including a rotating disk driving mechanism for rotating the rotating disk, the bottom wall of the rotating ball, A dust removal hole is formed by leaving a central portion supported by the rotating ball support mechanism and a spoke portion connecting the central portion and the peripheral wall.

In the present invention, dust falling from the rotating disk into the rotating ball hardly rides on the bottom wall of the rotating ball, and falls down through the dust drop hole provided on the bottom wall. . In this case, in most cases, there is no need to provide a special dust removing mechanism in the rotating ball.
There is little cost for waste disposal.

According to a sixth aspect of the present invention, there is provided a rotating ball having a component transfer flange projecting outward from an upper opening, a rotating disk disposed in an inclined position in the rotating ball, and the rotating ball rotatably supported. A rotating ball support mechanism, a mechanism base provided with the rotating ball support mechanism, a rotating ball driving mechanism for rotating the rotating ball, and a rotating disk driving mechanism for rotating the rotating disk, are provided on the bottom wall of the rotating ball. Is a rotating disk type article supply device provided with a dust drop hole for removing dust dropped here, and a large size is provided at least on the entire circumference of an area of the mechanism base opposed to the movement locus of the dust drop hole. It has a garbage outlet.

Therefore, most of the dust falling from the dust drop hole of the rotating ball falls through the dust drop opening of the mechanism base to below the mechanism base, and hardly gets on the mechanism base. For this reason, the trouble of cleaning dust on the mechanism base can be greatly reduced. Debris that falls below the mechanism base may be received by receiving a removable dust tray or the like below the dust dropper.

According to a seventh aspect of the present invention, there is provided a rotating ball having a component transfer flange projecting outward from an upper opening, a cylindrical surrounding wall surrounding the rotating ball from the side, and an inclined posture disposed in the rotating ball.

A rotating disk type article supply device including a rotating disk driving mechanism having a motor for rotating, a surrounding member surrounding a rotating ball supporting mechanism is provided between a rotating ball and a mechanism base, and each of the motors is provided. Is a waterproof type, and a plurality of surrounding wall mounting shafts are set up on the outer peripheral portion of the mechanism base.
Mounting on the enclosure wall, projecting outward from the upper opening
A flange is provided, and the mounting flange is attached to the enclosure wall mounting shaft.
Is fixed to the upper end by a screw .

In this way, even if water is applied to the mechanism base from the outside, it is possible to reliably prevent water from splashing on members that dislike water, such as the ball bearings of the rotating ball support mechanism and oil-impregnated metal. Even if the water hung on the inside hits the drive mechanism, there is no problem with the motor, so that the rotating ball can be washed easily and cleanly. Also ,
Since the mounting and dismounting of the enclosing wall can be performed very easily, it is possible to easily wash the rotating ball with the enclosing wall removed.

The belt winding groove 3 of the rotating ball 5
A V-belt 47 is stretched endlessly between 9a and the belt pulley 49. Therefore, when the first motor 45 is driven, the rotating ball 5 is rotated, and each time the rotating ball 5 makes one rotation, the dust hole 44 passes above the dust hole 19 b of the mechanism base 19. The rotating direction of the rotating ball 5 is clockwise as viewed from above.

The rotating disk drive mechanism 11 comprises a second motor 51 having a speed reduction mechanism, a vertically long cylindrical bearing housing 53, a rotating disk mounting disk 55, and the like. The bearing housing 53 is fixed to the output side end surface of the casing of the second motor 51,

The second motor 51 is also of a waterproof type.

The rotating disk mounting disk 55 has a disk shape having a diameter more than half the size of the upper opening 35a of the rotating ball 5. A boss shaft (not shown) protrudes downward from the center of the rotating disk mounting disk 55. The boss shaft is rotatably supported by the upper end of the bearing housing 53 and is connected to the output shaft 51a of the second motor 51 via a connection shaft (not shown). Therefore, the rotating disk mounting disk 55 is positioned inside the main part 35 of the rotating ball 5 in a posture inclined by about 15 ° with respect to the horizontal direction, and is rotated by the driving of the second motor 51. The upper opening of the bearing housing 53 is provided with an O-ring 56 (see FIG. 2) to maintain a watertight state.

The rotating disk 9 is in the form of a circular flat plate having a diameter slightly smaller than the diameter of the upper opening 35a of the main portion 35 of the rotating ball 5, and its center is located at the center of the rotating disk mounting disk 5.
5 is fixed to a central portion by a bolt (not shown). Therefore, the rotating disk 9 is disposed inside the main part 35 of the rotating ball 5 in a posture inclined by about 15 ° with respect to the horizontal direction. The outer peripheral edge 9a of the rotating disk 9 is close to the inner peripheral surface 38a of the peripheral wall 38 in the main portion 35 of the rotating ball 5, and at the highest position is in the same plane as the upper opening 35a of the rotating ball 5. It is located near the bottom wall 41 at the lowest point.

There are prepared several types having different materials, degrees of surface treatment, and the like, and the most suitable one is selected and attached according to the purpose of using the rotating disk type article supply device 1.

Since the rotating disk 9 is positioned inside the rotating ball 5 in an inclined position, a space 61 having a certain size is left below the highest side from the center of the rotating disk 9. The dust removing mechanism 13 is provided in the space 61.

Reference numeral 63 denotes a support arm on the original side of the dust removing mechanism 13.
Two original support arms 63 are provided. One end of the base side support arm 63 is fixed to the outer peripheral surface of the upper end of the bearing housing 53, and is provided in a slightly inclined position so as to extend toward the largest portion of the space 61. I have. A rod 65 extends horizontally across the other end of the original support arm 63, and a front support arm 67 extends from an intermediate portion of the rod 65. A squeegee mounting arm 69 extends from an intermediate portion and a distal end of the front support arm 67, and a first squeegee 71 and a second squeegee 73 are separately mounted on the distal end of the squeegee mounting arm 69.

The two squeegees 71 and 73 have different shapes such as a horizontally long flat plate-shaped one and a brush-shaped one.
Several types such as those having the same form but different materials are prepared, are detachably mounted on the squeegee mounting arm 69, and are substantially perpendicular to the upper surface of the outer region 41a on the bottom wall 41 of the rotating ball 5.

When viewed from above, the two squeegees 71 and 73 are oriented in a substantially C-shape that opens toward the center of the rotating ball 5, and are located counterclockwise from the front support arm 67. The first squeegee 71 is separated from the inner peripheral surface 35b of the rotating ball 5, and the second squeegee 73 is extremely close to the inner peripheral surface 35b.

When the rotating ball 5 rotates, the two squeegees 71 and 73 relatively squeeze the upper surface of the outer region 41a of the bottom wall 41. Since the dust drop hole 44 is provided in the outer area 41a, the squeegees 71 and 73 pass over the dust drop hole 44 each time the rotating ball 5 makes one rotation. The squeegees 71 and 73 are mounted on the squeegee mounting arm 69 by bolts 75 that pass through long holes (not shown) formed at the distal end of the squeegee mounting arm 69. The position in the direction and the dimension L between these tips (see FIG. 5) can be adjusted by adjusting the mounting position with respect to the squeegee mounting arm 69. The squeegees 71 and 73 are located almost directly above the dust drop opening 19b formed in the mechanism base 19.

A gasket 77 as a surrounding member is provided in a narrow space between the mechanism base 19 and the rotating ball 5. This gasket 77 has an annular shape,
The mechanism base 19 surrounds the bearing support member 31.

It is in elastic contact with the lower surface. With this gasket 77,
Water is prevented from being applied to the ball bearing 33 from at least between the mechanism base 19 and the rotating ball 5.

A rubber wiper 79 is attached to the lower surface of the bottom wall 41 of the rotating ball 5 (see FIGS. 1 and 2). The wiper 79 is provided in a posture extending in the radial direction of the bottom wall 41 and in contact with the upper surface of the mechanism base 19. Therefore, while the rotating ball 5 is rotating, a region of the upper surface of the mechanism base 19 outside the gasket 77 is cleaned by the wiper 79.

Reference numeral 81 denotes an enclosure wall. This enclosure 81
It has a cylindrical shape having a diameter slightly larger than the outer diameter of the mechanism base 19 for surrounding the rotating ball 5 and supporting a component transfer guide described later, and has a height equal to the height of the rotating ball 5. It is about 1.5 times. A flange 83 projects outward from an upper opening of the surrounding wall 81, and four mounting holes 83a arranged at equal intervals in the circumferential direction are formed in the flange 83. Also,
A large number of bolt through holes 81a (see FIG. 3) arranged in the circumferential direction are formed in an upper portion of the surrounding wall 81.

The surrounding wall 81 is provided with the flange 8
3 is the surrounding wall mounting shaft 27 provided on the mechanism base 19;
Screw 85 placed on the upper end surface of the
Is screwed into the screw hole 27 a of the surrounding wall mounting shaft 27, thereby being attached to the surrounding wall mounting shaft 27. When the surrounding wall 81 is attached, the rotating ball 5 fits so as to be hidden in the surrounding wall 81.

One or a plurality of component transfer guides 87 (see FIGS. 2 and 4) are mounted inside the surrounding wall 81. The component transfer guide 87 is formed in the shape of a flexible metal strip, and is supported by the distal ends of a large number of support bolts 89 (see FIG. 4) attached through bolt through holes 81a of the surrounding wall 81. The component transfer guide 87 is located above the component transfer flange 37 of the rotating ball 5 and is slightly spaced therefrom, and forms a component transfer path in cooperation with the component transfer flange 37. The rotating disk type article supply device 1 is configured as described above.

Next, the method of use and operation of the rotating disk type article supply apparatus 1 will be described. Prior to the start of operation, a rotating disk 9 suitable for a target component is selected and mounted on the rotating disk mounting disk 55. If dust comes out of the component, squeegees 71 and 73 corresponding to the type of the dust are squeegeeed. Attach to the mounting arm 69. A conveyor or other desired transportation means is connected to the tip of the component transfer guide 87 through an outlet (not shown) provided in the enclosure wall 81. And
A target component is put into the rotating ball 5. This input is
It may be before or after the rotating ball 5 starts to rotate. The charging method may be manual operation or automatic charging using a conveyor or the like. The loaded parts are placed on the rotating disk 9.

When the rotating disk type article supply device 1 starts operating, the rotating ball 5 and the rotating disk 9 rotate. Then, the parts on the rotating disk 9 are subjected to centrifugal force and gather toward the inner peripheral surface 38a of the rotating ball 5 to turn, and when they reach the highest position of the turning locus, they are located at the outermost position. The object moves on the component transfer flange 37 of the rotating ball 5. The parts transferred on this part transfer flange 37 are:
While being guided along the movement path by the component transfer guide 87, they move in a line and drop through the outlet of the surrounding wall 81 to the transportation means.

When dust such as powder comes out of the component, the dust 91 (see FIG. 5) is removed from the inner peripheral surface 38a of the rotating ball 5.
From the gap between the outer peripheral edge 9a of the rotating disk 9 and the bottom wall 4
1 on the outer region 41a. This garbage 91 is
The squeegees 71 and 73 collect the squeegees and drop them in the trash drop holes 44. That is, as shown in FIG. 5, the dust 91 that has fallen on the bottom wall 41
Is gathered outward (to the side of the peripheral wall 38) by hitting
Next, immediately after coming off the first squeegee 71, it hits the second squeegee 73 and is now gathered inward. In this way, almost all of the dust 91 is gathered, and when the dust drop hole 44 has come around, it is dropped from the dust drop hole 44. The trash 91 dropped from the trash drop hole 44 falls into the chute 29 through the trash drop 19b of the mechanism base 19 and is collected.

Since the removal of dust by the squeegees 71 and 73 is performed as described above, unlike the case where one squeegee completely blocks the dust, the dust is moved while constantly flowing and the flowing direction is swung right and left. To be collected,
There is little clumping as a lump, and it falls from the dust drop hole 44 quite smoothly. If this drop is not smooth, the dimension L between the tips of the squeegees 71 and 73
Adjust That is, if the dimension L is too small, the dust is likely to solidify, and if the dimension L is too large, the stirring effect due to the change in the flow direction of the dust becomes small.

A part of the dust 91 on the bottom wall 41 falls to some extent on the upper surface of the mechanism base 19 while the dust drop hole 44 turns. The trash 91 that has fallen here is the wiper 79
And is dropped by the chute 29 when it comes to the trash outlet 19b.

Most of the cleaning of the rotating disk type article supply device 1 can be performed with water. That is, the surrounding wall 81
3, the entire rotating ball 5 is exposed as shown in FIG. 3, and a portion of the mechanism base 19 outside the gasket 77 is exposed. When the rotating disk 9 is removed, the outer region 41a on the inner bottom surface of the rotating ball 5 is exposed. Therefore, in this state, the rotating ball 5 can be washed both inside and outside, and the dust 91 remaining on the mechanism base 19 can be easily washed away. In this case, even if water is applied to the mechanism base 19, there is no possibility that the ball bearing 33 or the like will be exposed to water because of the gasket 77. Also, even if the water that has washed the inside of the rotating ball 5 falls into the space 23, the first motor 45 and the second motor 51 are waterproof, so that no failure occurs.

Since the rotating disk mounting disk 55 is detachably mounted on a connecting shaft (not shown), when it is necessary to carefully wash the upper end of the shaft housing 53, etc.
What is necessary is just to remove the rotating disk mounting disk 53. In this case, since the upper opening of the bearing housing 53 is made water-tight by the O-ring 56, water does not splash inside the bearing housing 53.

FIGS. 6 to 8 show a rotating disk type article supply apparatus 1A according to a second embodiment of the present invention. This rotary disk type article supply apparatus 1A is largely different from the rotary disk type article supply apparatus 1 only in the structure of the mechanism base, the driving method of the rotary ball, and the dust removing mechanism. Therefore, the description will be made only on the above-mentioned differences and the points related thereto, and the remaining portions will be denoted by the same reference numerals as those of the same parts in the rotary disk-type article supply device 1 in the respective parts of the drawing. The description will be omitted.

As shown in FIG. 8, a mechanism base 19A in the rotary disk type article supply apparatus 1A has a circular central portion 93 having a circular central hole 19a formed therein and extends radially from the central portion 93. It comprises four horizontal arms 97, and the arms 97 are provided at 90 ° intervals in the circumferential direction. The space between the two arms 97 adjacent to each other is a trash drop 99
Function as A mounting shaft for supporting the surrounding wall 81 is provided upright at the tip of the arm 97.

The driving of the rotating ball 5 employs a gear driving method. That is, a flat gear 101 is formed on the outer peripheral surface of the lower end of the supported portion 39 of the rotating ball 5, and a driving gear 103 having a flat gear shape is attached to the output shaft of the first motor 45. The driving gear 103 is the flat gear 101
Is engaged.

The dust removing mechanism 13A in the rotating disk type article supply apparatus 1A uses an air-assisted method. The dust drop hole 44 of the rotating ball 5 is located near the corner where the bottom wall 41 and the peripheral wall 38 are continuous. Three are formed at equal intervals in the circumferential direction. (The number of the trash drop holes 44 is not limited to three.)

The dust removing mechanism 13A includes a support arm 105 protruding from the upper end of the bearing housing 53,
Squeegee 107 and air nozzle 10 attached to
9 and so on. The squeegee 107 extends in the radial direction of the rotating ball 5 and extends in the outer region 4 of the bottom wall 41.
1a and lightly contact the lower end of the inner peripheral surface of the peripheral wall 38. An air hose 111 extends from an air compressor (not shown) and is guided along the bearing housing 53 and connected to the air nozzle 109. Air nozzle 1
09 is a squeegee 107 of the rotation locus of the dust drop hole 44.
Are provided in such a direction as to be directed to a place close to the counterclockwise side. Therefore, when the dust drop hole 44 comes to a position facing the air nozzle 109, high-pressure air from the air nozzle 109 blows through the dust drop hole 44.

The dust falling on the bottom wall 41 is relatively raked by the squeegee 107, and falls from the dust drop hole 44 when the dust drop hole 44 passes below the dam plate 107. This drop is forced not only by the dead weight of the dust but also by the blowing action of the high-pressure air from the air nozzle 109. Therefore, even highly viscous dust can be almost certainly eliminated. Further, most of the mechanism base 19A except for the central portion 93 is a large dust drop hole 99, so that dust spilled from the dust drop hole 44 hardly remains on the mechanism base 19A and passes through the window 99 to be lowered. Go down.

In some cases, the squeegee 10 may be connected to an air nozzle 109 'shown by a two-dot chain line in FIG.
It is also conceivable to provide the squeegee 10 with a squeegee 10 by providing a bridge or the like to the trash drop hole 44 so as to blow off only the trash.
It is also conceivable to arrange them on both sides with 7 interposed.

It is conceivable that the ejection timing of the air ejected from the air nozzle 109 is an intermittent type synchronized with the timing at which the dust dropping hole 44 faces the air nozzle 109. Further, depending on the type and form of dust coming out of the parts, it is conceivable that the dust removing mechanism is of a flushing type. In particular, when a waterproof gasket 77 is disposed between the rotating ball 5 and the mechanism bases 19 and 19A as in the respective embodiments shown in the drawings, or when a waterproof motor is used, the inside of the rotating ball 5 is used. There is no problem even if water splashes, so if a fountain nozzle is provided in place of the air nozzle 109, it is possible to have a function of constantly washing the inside of the rotating ball with water, not just dust removal. .

FIG. 9 shows another embodiment of the rotating ball. In the rotating ball 5A shown in this figure,
Most of the outer area of the bottom wall 41 is a dust drop hole 121. That is, the bottom wall 41 has a dust removal hole 121 except for a central portion 41c and only four spoke portions 41d connecting the central portion 41c and the peripheral wall 38.
Therefore, the dust falling from the rotating disk 9 hardly rides on the bottom wall 41 and falls down through the dust drop hole 121. In this case, the dust may be removed by setting the mechanism base as shown in FIG. 8A or by attaching the wiper 79 to the lower surface of the spoke portion 41d. This eliminates the need to provide a special dust removing mechanism in the rotating ball 5A, so that a low-cost dust disposal means is sufficient.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Are also included in the present invention. For example, in carrying out the present invention, a combination of the C-shaped squeegee shown in the first embodiment and the fluid ejection nozzle shown in the second embodiment may be used.
In the first embodiment, the squeegee is provided in the shape of a square, but the squeegee may not be arranged in the shape of a square or may be provided with one squeegee.

[0063]

As described above, according to the first and second aspects of the present invention, dust falling inside the rotating ball is always gathered by the squeegee and dropped from the dust drop hole. In addition, dust hardly accumulates on the inside of the rotating ball, so that the labor for cleaning can be largely saved. In particular,
In the present invention, the squeegee does not merely block the dust, but falls from the dust drop hole in a state of flowing while being gathered outward and inward by the two squeegees having a C-shape. The garbage can be collected and there is no possibility that the collected garbage will be compacted.

According to the third aspect of the present invention, dust falling inside the rotating ball is dropped from the dust drop hole while being gathered by a squeegee, or the dust falls into the dust drop hole and becomes trapped. However, since it is blown off by the fluid ejected from the fluid ejecting nozzle, in any case, dust hardly accumulates inside the rotating ball, and the labor for cleaning can be greatly reduced. In particular, in the present invention, dust is forcibly blown off by at least the fluid ejected from the fluid ejection nozzle, so that even highly viscous dust can be more reliably removed.

According to the fourth aspect of the present invention, since the wiper always rotates integrally with the rotating ball, the wiper constantly sweeps the upper surface of the mechanism base and falls there while the apparatus is operated. Collect garbage.

According to the fifth aspect of the present invention, dust falling from the rotating disk into the rotating ball hardly rides on the bottom wall of the rotating ball, and passes through the dust drop hole provided on the bottom wall. Since it falls down, there is no need to provide a special dust removing mechanism in the rotating ball.

According to the sixth aspect of the present invention, most of the dust falling from the dust drop hole of the rotating ball falls through the dust drop opening of the mechanism base to below the mechanism base and rides on the mechanism base. Is almost none. For this reason, the trouble of cleaning dust on the mechanism base can be greatly reduced.

According to the seventh aspect of the present invention, even if water is applied to the mechanism base from outside, it is possible to reliably prevent water from being applied to the ball bearings and the like of the rotating ball support mechanism, and the water is hung inside the rotating ball. Even if water is applied to the drive mechanism, there is no problem with the motor, so that the rotating ball can be washed easily and cleanly. Also, it is very important to attach and detach the enclosure wall.
It can be easily done in a state where the surrounding wall is removed
The washing of the rotating ball in a state can be easily performed.
