Description
METHOD OF DUST REMOVING IN THE FORM OF AIR ASPIRATION AND
APPARATUS THEREFOR
1. Field of the Invention The present invention relates to a method and apparatus for performing an air suction dust-removing, and more particularly to those capable of releasing waste thread and polishing powder deposited on the surface of a vehicle body to be sucked to be removed.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG.1, a work cleaning apparatus 1 reads out a profile of a vehicle body 9 conveyed by a conveyer 8 by means of sensor means to automatically control the height of a dust-removing apparatus 2.
In the construction of the apparatus 1, riding over the conveyer 8, between gate-like formed frames 22, a pair of support members 24 are disposed on the opposite sides of conveyer 8. On the opposite sides of the supports 24, a pair of guide rails 25 are mounted, along which the vertically movable slidable members 30 and a base plate 26 therebetween are provided. On the ends of the base plate 26, a pair of support arms 27 in the forward direction of the conveyer 8 and broader than the width of the body 9 are provided so as to extend, and a dust-removing apparatus 2 is interposed.
In the downstream direction of conveyer 8, supports 20 are provided, sensor arrays 21 are provided. Beneath the work, a servomotor 37 is mounted to vertically actuate the slidable members 30.
The silhouette data produced by the sensors 21 are processed to produce a instruction signal, by which the clearance between the body and the brush is optimally maintained.
As in FIG.2, housing 7 is formed as a fun, which is supported with both ends by arms 27.
On one side of housing 7, an air motor 50 is mounted, on which shaft 50a is a crank connecting member 55 is connected, on the ends thereof, a swing arm 54 with a long opening 54a, to which a pin 55a of the member 55 is swingably engaged.
A dust-removing brush 52 is mounted in the opening of housing 7. Brush 52 is formed of a body 52a and bristles 53, which are of non-conductive material such as horse-hair or carbon fiber formed with wound fibers. Air inlet opening 52a are formed, but these may be separately formed when enabled to introduce suction air.
Upon operation of blower, the air in the housing 7 is exhausted through the duct 29 and absorbed from the end of bristles 53 to inlet opening 52b of the body 52a. By the suction air, the dust released from the surface of body 9 is introduced from inlet opening 52b into housing 7.
It is necessary the suction air is provided with suction ability sufficient to absorb the released dust into housing 7. For example, to sufficiently collect the polishing powder or waste thread on the surface, an air flow having a flowing speed of 0.3 to 0.5 m/s is necessary to be maintained.
Also, to flow the suction air through bristles 53 with efficiency, the clearance formed between the main body 52a and the opening region of housing 7 should be as small as possible within the range not causing interference between the brush 52 and housing 7, and preferably the clearance may be covered with a flexible sheet or the like.
The support shaft 28 extends from the both ends of main body 52a, one of the shaft 28 is rotatably supported to housing 7 through a bearing, not shown, while the other is secured to the other end of swing arm 54 outside the housing 7.
When the air motor is actuated, the pin 55a being rotated along an arcuate locus, the rotation is converted to a swing motion of swing arm 54 forward and backward. This swing motion causes the dust-removing brush 52 to in turn swing around the axis of shaft 28, the swinging range of the brush 52 being always caused in the manner that the end of bristles 53 engage the surface of the body 9.
The air motor 55, connecting member 55 and swing arm 54 together form a swing motion causing arrangement, which is not limited therein. Another example may be formed of a servomotor, a pinion and a threaded lack, by repetition of reciprocal motion of the servomotor, to cause the swing motion of the swing arm and dust-removing brush 52. Also, another arrangement may be formed by a reciprocal motion of an air cylinder to cause the brush 52 to swing.
In operation, when a vehicle body 9 is conveyed along the conveyer 8, the sensor array 21 reads the profile of the body 9, and a controller (not shown) for the work cleaning apparatus 1 actuates the servomotor 37 to maintain the dust-removing apparatus 2 in the height relative to the surface of the body optimal for performing dust-removing operation.
When the air motor 50 is actuated and the swing arm 54 swings, the brush 52 also swings in the horizontal direction along the advancing direction of the body 8, where the contact condition of the surfaces of the bristles 53 and body 9 is maintained, and, since the brush 52 is formed slightly broader than the width of body 9, a single swing motion of brush 52 allows the cleaning motion over the entire width of body 9.
According to the movement of the body 9 by the conveyer 8, the bristles 53 of the brush 52 are moved in the forward and backward directions with the dust on the body surface being continuously wiped away. At the time, since the suction 21 696~1 air is continuously being introduced along the bristles 53 into housing 7, the released dust from the body surface is suctioned into housing 7 together with the air and flow through the exhaust duct 29 to be exhausted out of the cleaning apparatus.
As the bristles 53 are formed of a non-conductive material such as horse hair or carbon fiber, both the generation of static electricity by friction with the body and the accumulation of dust by the generated static charge, in addition, also the dust deposition onto the body are all prevented.
Profiling the shape of body 9, the height of dust-removing apparatus 2 is controlled. The position control thereof is hereinafter described with reference to FIG. 4.
As previously stated, slidable members 30 are arranged to support guide rails 25 disposed on the opposed walls of the support 24 from outside the support 24. Provided on the both ends of the slidable members 30 are rollers 61 rotatable around an axis in parallel with the axis of conveyer 8 and engaged with the external side surface of guide rails 25. On the other hand, other rollers 62 rotatable around an axis orthogonal to that of conveyer 8 are provided so as to engage with the opposite surface of the guide rails 25.
Bridged between the slidable members 30 is a base plate 26, on both ends of which a support arm 27 is mounted so as to extend in the downstream direction of the conveyer 8. Further on both ends of the arm 27, the housing 7 with dust-removing brush 52 is mounted. The slidable members 30, base plate 26 and support arm 27 are disposed for vertical movement as an integral member along guide rail 25. In addition, the brush 52 and body 9 are spaced apart from each other by a predetermined distance based on the support arm 27 as the standard member for positioning.
Rotatably supported on the top of the frame 22 are rotating shafts 63, adjacent the support member 24 of each of which shafts 63 a pulley 64 is supported on the side of conveyer 8. On each end of the vertical support of the frame 22, a rotating shaft 65 is mounted between the inner and outer walls in parallel with the shaft 63, and a pulley is provided opposed to each of the pulleys 64.
Supported around a pulley 64 and a pulley 66 is a belt 67, which has its end secured to the base plate 26. Further, the belt 67 has its other vertical branch mounted a balance weight 68 for providing a smooth vertical motion of support arm 27.
Arranged beneath the shaft 65 is a servomotor, which has its drive shaft secured to a chain-sprocket 39a, and also another chain-sprocket 39b is secured on the shaft 65 in the position to be coupled to the first sprocket 39a, both of which are operatively coupled by a chain bridged therearound.
The rotating power of servomotor 37 is transmitted to shaft 65 via the chain, and further, via another belt 67, to the upper rotating shaft 63, thereby causing vertical movement of slidable members 30.
In the position downstream the cleaning apparatus 1 with respect to forward direction of conveyer 8, a plurality of horizontal members 69 is mounted on the support 20 formed in the shape of a ladder on both sides of conveyer 8, and, on the opposite surfaces of the support 20, sensor arrays 21 are mounted, spaced apart from each other having a pitch of 20 mm.
A drive motor 70, whose rotating speed can be set in accordance with the moving speed of the conveyer 8 such that one pulse is generated every time the conveyer 8 moves for 20 mm, is equipped with a rotary encoder 71 which serves as means for generating signals with a predetermined time interval.
FIG.5 is a schematic view of a control device for the position control means provided with the aforementioned rotary encoder, and FIG.6 is a flow chart showing the flow of such control operation.
The data transmitted from a rotary encoder 71 and also the silhouette data of the body 9 from sensor arrays 21 are applied to a control device 22 and computed therein to control the operation of servomotor 37 provided in the work cleaning apparatus 1.
In the step S1, when a vehicle body 9, which is placed on a carrier 8a of conveyer 8, approaches from the side of cleaning apparatus 1, the silhouette or profile of the body 9, which namely represents the shape ranging from the bonnette through the roof or gate to the trunk lid, is detected by means of sensor arrays 21 each arranged along a support 20.
Also, the data therefrom are applied to the control device 72. In step S2, the silhouette data of the vehicle body detected by the arrangement of the sensor arrays 21 and a digital data obtained by conversion of the moving velocity of conveyer 8 are transmitted and applied to a control device 72.
In such a manner, the velocity of conveyer 8 is converted to a digital data by the rotary encoder 71, which is applied to the control device 72.
In the step S3, on the basis of the data of the body silhoutte and of moving velocity of the conveyer 8, the direction and velocity to be provided for the servomotor 37 is determined. Then, in the step S4, the servomotor 37 is controlled so as to move the slidable members 30 in the vertical direction in accordance with the body silhouette to cause the vertical movement of the brush 52 to continuously maintain a clearance between the body 9 and brush 52 as optimal for performing dust-removing operation.
In this connection, the present invention is particularly effective when installed in the coating line of the automobile industry. In the first step of undercoating of an automobile body prior to electrodeposition coating, the body surface is polished, and, in the process of removing the polishing powder and powder dust, the method of the invention can be effectively applied. Such the dust cannot be removed by the usual method using water.
Although the invention is described in the embodiment of cleaning of the vehicle body, but also can be applied to cleaning of the other works or objects.
APPARATUS THEREFOR
1. Field of the Invention The present invention relates to a method and apparatus for performing an air suction dust-removing, and more particularly to those capable of releasing waste thread and polishing powder deposited on the surface of a vehicle body to be sucked to be removed.
2. Brief Description of the Prior Art FIG.7 shows the pricipal part of a conventional air-suction type dust-removing apparatus, in which a rotatable dust-removing brush 152 comprising a plurality of radially mounted goose-feather 135 around a shaft supported at both ends to the housing 107, not shown, is mounted in a housing 107 connected to the exhaust duct 129. In the housing 107, drive means such as a servomotor, not shown, for rotating dust-removing brush 152. The dust-removing brush 152 is arranged so as to engage the goose-feather 135 with the surface of a vehicle body 109, which brush is rotated in the direction X to release the waste thread or dust to be suctioned by suction air through duct 129.
The dust-removing apparatus 102 is installed to a work cleaning apparatus capable of maintaining the clearance between the body 109 and dust-removing apparatus 2 in an optimal condition, with being vertically moved along the profile of the work such as a vehicle body 109.
In the conventional apparatus 102, the dust-removing 2169~91 brush 152 is rotated to remove the dust on the body 109, and the dust is likely to be strongly flown out to disperse around at the moment the feather end is separate from the surface.
Also, a strong air stream is produced around the brush 152, and the floating dust transported by the air can be dispersed around.
Accordingly, despite the air around the dust-removing brush 152 is continued to be suctioned through the duct, not so improved dust-removing effect is achieved, and the dust floating in the air is likely to deposit on the body 109.
An object of the invention is to properly suction the dust by releasing the dust from the surface of the work, to prevent dispersion of the dust and also reduce the amount of the dust floating in the air to prevent redeposition thereof on the work surface.
SUMMARY OF THE INVENTION
The present invention relates to a method of dust-removing using a cleaning apparatus of the type of air aspiration, and more particularly for releasing the dust including waste thread and polishing powder used for finishing after painting from the surface of a vehicle body, using a dust-removing brush, and through aspiration of the dust by suction air, and the cleaning apparatus in use for the dust-removing method.
Dust remaining on the surface of the work is allowed to be released from the surface during being contacted on the surface, the released dust being properly suctioned in the housing, the dust are effectively prevented from being dispersed around the work and from floating in the air to increase dust-removing ability.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIG.1, a work cleaning apparatus 1 reads out a profile of a vehicle body 9 conveyed by a conveyer 8 by means of sensor means to automatically control the height of a dust-removing apparatus 2.
In the construction of the apparatus 1, riding over the conveyer 8, between gate-like formed frames 22, a pair of support members 24 are disposed on the opposite sides of conveyer 8. On the opposite sides of the supports 24, a pair of guide rails 25 are mounted, along which the vertically movable slidable members 30 and a base plate 26 therebetween are provided. On the ends of the base plate 26, a pair of support arms 27 in the forward direction of the conveyer 8 and broader than the width of the body 9 are provided so as to extend, and a dust-removing apparatus 2 is interposed.
In the downstream direction of conveyer 8, supports 20 are provided, sensor arrays 21 are provided. Beneath the work, a servomotor 37 is mounted to vertically actuate the slidable members 30.
The silhouette data produced by the sensors 21 are processed to produce a instruction signal, by which the clearance between the body and the brush is optimally maintained.
As in FIG.2, housing 7 is formed as a fun, which is supported with both ends by arms 27.
On one side of housing 7, an air motor 50 is mounted, on which shaft 50a is a crank connecting member 55 is connected, on the ends thereof, a swing arm 54 with a long opening 54a, to which a pin 55a of the member 55 is swingably engaged.
A dust-removing brush 52 is mounted in the opening of housing 7. Brush 52 is formed of a body 52a and bristles 53, which are of non-conductive material such as horse-hair or carbon fiber formed with wound fibers. Air inlet opening 52a are formed, but these may be separately formed when enabled to introduce suction air.
Upon operation of blower, the air in the housing 7 is exhausted through the duct 29 and absorbed from the end of bristles 53 to inlet opening 52b of the body 52a. By the suction air, the dust released from the surface of body 9 is introduced from inlet opening 52b into housing 7.
It is necessary the suction air is provided with suction ability sufficient to absorb the released dust into housing 7. For example, to sufficiently collect the polishing powder or waste thread on the surface, an air flow having a flowing speed of 0.3 to 0.5 m/s is necessary to be maintained.
Also, to flow the suction air through bristles 53 with efficiency, the clearance formed between the main body 52a and the opening region of housing 7 should be as small as possible within the range not causing interference between the brush 52 and housing 7, and preferably the clearance may be covered with a flexible sheet or the like.
The support shaft 28 extends from the both ends of main body 52a, one of the shaft 28 is rotatably supported to housing 7 through a bearing, not shown, while the other is secured to the other end of swing arm 54 outside the housing 7.
When the air motor is actuated, the pin 55a being rotated along an arcuate locus, the rotation is converted to a swing motion of swing arm 54 forward and backward. This swing motion causes the dust-removing brush 52 to in turn swing around the axis of shaft 28, the swinging range of the brush 52 being always caused in the manner that the end of bristles 53 engage the surface of the body 9.
The air motor 55, connecting member 55 and swing arm 54 together form a swing motion causing arrangement, which is not limited therein. Another example may be formed of a servomotor, a pinion and a threaded lack, by repetition of reciprocal motion of the servomotor, to cause the swing motion of the swing arm and dust-removing brush 52. Also, another arrangement may be formed by a reciprocal motion of an air cylinder to cause the brush 52 to swing.
In operation, when a vehicle body 9 is conveyed along the conveyer 8, the sensor array 21 reads the profile of the body 9, and a controller (not shown) for the work cleaning apparatus 1 actuates the servomotor 37 to maintain the dust-removing apparatus 2 in the height relative to the surface of the body optimal for performing dust-removing operation.
When the air motor 50 is actuated and the swing arm 54 swings, the brush 52 also swings in the horizontal direction along the advancing direction of the body 8, where the contact condition of the surfaces of the bristles 53 and body 9 is maintained, and, since the brush 52 is formed slightly broader than the width of body 9, a single swing motion of brush 52 allows the cleaning motion over the entire width of body 9.
According to the movement of the body 9 by the conveyer 8, the bristles 53 of the brush 52 are moved in the forward and backward directions with the dust on the body surface being continuously wiped away. At the time, since the suction 21 696~1 air is continuously being introduced along the bristles 53 into housing 7, the released dust from the body surface is suctioned into housing 7 together with the air and flow through the exhaust duct 29 to be exhausted out of the cleaning apparatus.
As the bristles 53 are formed of a non-conductive material such as horse hair or carbon fiber, both the generation of static electricity by friction with the body and the accumulation of dust by the generated static charge, in addition, also the dust deposition onto the body are all prevented.
Profiling the shape of body 9, the height of dust-removing apparatus 2 is controlled. The position control thereof is hereinafter described with reference to FIG. 4.
As previously stated, slidable members 30 are arranged to support guide rails 25 disposed on the opposed walls of the support 24 from outside the support 24. Provided on the both ends of the slidable members 30 are rollers 61 rotatable around an axis in parallel with the axis of conveyer 8 and engaged with the external side surface of guide rails 25. On the other hand, other rollers 62 rotatable around an axis orthogonal to that of conveyer 8 are provided so as to engage with the opposite surface of the guide rails 25.
Bridged between the slidable members 30 is a base plate 26, on both ends of which a support arm 27 is mounted so as to extend in the downstream direction of the conveyer 8. Further on both ends of the arm 27, the housing 7 with dust-removing brush 52 is mounted. The slidable members 30, base plate 26 and support arm 27 are disposed for vertical movement as an integral member along guide rail 25. In addition, the brush 52 and body 9 are spaced apart from each other by a predetermined distance based on the support arm 27 as the standard member for positioning.
Rotatably supported on the top of the frame 22 are rotating shafts 63, adjacent the support member 24 of each of which shafts 63 a pulley 64 is supported on the side of conveyer 8. On each end of the vertical support of the frame 22, a rotating shaft 65 is mounted between the inner and outer walls in parallel with the shaft 63, and a pulley is provided opposed to each of the pulleys 64.
Supported around a pulley 64 and a pulley 66 is a belt 67, which has its end secured to the base plate 26. Further, the belt 67 has its other vertical branch mounted a balance weight 68 for providing a smooth vertical motion of support arm 27.
Arranged beneath the shaft 65 is a servomotor, which has its drive shaft secured to a chain-sprocket 39a, and also another chain-sprocket 39b is secured on the shaft 65 in the position to be coupled to the first sprocket 39a, both of which are operatively coupled by a chain bridged therearound.
The rotating power of servomotor 37 is transmitted to shaft 65 via the chain, and further, via another belt 67, to the upper rotating shaft 63, thereby causing vertical movement of slidable members 30.
In the position downstream the cleaning apparatus 1 with respect to forward direction of conveyer 8, a plurality of horizontal members 69 is mounted on the support 20 formed in the shape of a ladder on both sides of conveyer 8, and, on the opposite surfaces of the support 20, sensor arrays 21 are mounted, spaced apart from each other having a pitch of 20 mm.
A drive motor 70, whose rotating speed can be set in accordance with the moving speed of the conveyer 8 such that one pulse is generated every time the conveyer 8 moves for 20 mm, is equipped with a rotary encoder 71 which serves as means for generating signals with a predetermined time interval.
FIG.5 is a schematic view of a control device for the position control means provided with the aforementioned rotary encoder, and FIG.6 is a flow chart showing the flow of such control operation.
The data transmitted from a rotary encoder 71 and also the silhouette data of the body 9 from sensor arrays 21 are applied to a control device 22 and computed therein to control the operation of servomotor 37 provided in the work cleaning apparatus 1.
In the step S1, when a vehicle body 9, which is placed on a carrier 8a of conveyer 8, approaches from the side of cleaning apparatus 1, the silhouette or profile of the body 9, which namely represents the shape ranging from the bonnette through the roof or gate to the trunk lid, is detected by means of sensor arrays 21 each arranged along a support 20.
Also, the data therefrom are applied to the control device 72. In step S2, the silhouette data of the vehicle body detected by the arrangement of the sensor arrays 21 and a digital data obtained by conversion of the moving velocity of conveyer 8 are transmitted and applied to a control device 72.
In such a manner, the velocity of conveyer 8 is converted to a digital data by the rotary encoder 71, which is applied to the control device 72.
In the step S3, on the basis of the data of the body silhoutte and of moving velocity of the conveyer 8, the direction and velocity to be provided for the servomotor 37 is determined. Then, in the step S4, the servomotor 37 is controlled so as to move the slidable members 30 in the vertical direction in accordance with the body silhouette to cause the vertical movement of the brush 52 to continuously maintain a clearance between the body 9 and brush 52 as optimal for performing dust-removing operation.
In this connection, the present invention is particularly effective when installed in the coating line of the automobile industry. In the first step of undercoating of an automobile body prior to electrodeposition coating, the body surface is polished, and, in the process of removing the polishing powder and powder dust, the method of the invention can be effectively applied. Such the dust cannot be removed by the usual method using water.
Although the invention is described in the embodiment of cleaning of the vehicle body, but also can be applied to cleaning of the other works or objects.
