  For example, the hanger 25 includes a pair of vertically hanging arms, ie, four arms 26, 26, 27, and 27 in the illustrated example. The pair of front hanger arms 26, 26 are arranged side by side at a distance slightly wider than the width of the automobile body 30, and the lower portions of the respective hanger arms 26, 26 are formed inwardly bent. The automobile body 30 is supported by the bent portion 26a.

  The pair of hanger arms 27, 27 on the rear side of the hanger 25 are also arranged at a slightly wider interval than the vehicle width, like the front hanger arms 26, 26, and are bent at the inside of the lower part. The automobile body 30 is supported. Further, the upper portions of the front and rear hanger arms 26 and 27 on the right side of the hanger 25 are connected by a connecting portion 28, and the upper portions of the front and rear hanger arms 26 and 27 are similarly connected by the connecting portion 28 on the left side of the hanger 25. Yes. The hanger 25 configured as described above is suspended from the trolley 22 while supporting the automobile body 30.

  Although not shown, each trolley 22 is actually connected to a drive roller that rolls on a power rail disposed above the trolley guide rail 21, and this drive roller is connected to the power rail. By traveling on the trolley 22, the trolley 22 is pulled and moved along the trolley guide rail 21, and the automobile body 30 is transported.

  However, in the conventional paint cleaning machine 40, since the bar 42 extends so as to cross the traveling direction of the hanger 25, if the bar 42 does not move in this state, as shown by an arrow A in FIG. The arms 26 and 27 of the hanger 25 collide with the bar 42. In order to avoid such a collision, when the arms 26 and 27 of the hanger 25 approach the bar 42, it is conceivable to move the bar 42 so as to deviate from the traveling direction of the hanger 25. However, as shown in FIG. 9, when the bar 42 is moved when the bar 42 comes close to the arms 26 and 27 of the hanger 25, for example, the body surface in the region A in FIG. The cleaning with the sheet is interrupted in spite of the fact that it is not broken, so that wiping remains.

  An object of the present invention is to provide a cleaning machine that can clean the entire work surface such as an automobile body with a simple structure.

  In order to achieve this object, in the cleaning machine of the present invention, the first arm driving device and the second arm driving device are installed facing each other so as to sandwich the movement trajectory of the hanger, and follow the movement direction of the hanger. The first arm driving device is configured such that a front arm arranged on the moving direction side and a rear arm arranged on the opposite side of the moving direction along the moving direction of the hanger can rotate in the horizontal direction and move up and down. The front arm disposed on the movement direction side along the movement direction of the hanger and the rear arm disposed on the opposite side of the movement direction along the movement direction of the hanger are horizontally rotatable and are vertically movable. A bar, which is provided in the second arm drive device and is suspended from the first arm drive device and the second arm drive device, is laid horizontally so that the workpiece does not contact the cleaning member. The workpiece is cleaned by passing under the bar, and when each rear arm is at a position deviating from the movement trajectory of the hanger, one end of the bar is connected to the first arm driving device. In addition to being supported by the front arm, the other end of the bar is supported by the front arm of the second arm drive device, and each rear arm is rotated and raised with each front arm supporting the bar. Each front arm is supported by each rear arm, and with each rear arm supporting the bar, the front arm is moved to a position deviated from the movement trajectory of the hanger. It is characterized by the fact that it has been changed.

  Further, in the cleaning machine of the present invention, the front arm includes a sensor for detecting the hanger, and when the sensor detects the approach of the hanger, each of the first and second arm driving devices is a bar. Is changed from the front arm to the rear arm.

  Furthermore, in the cleaning machine of the present invention, a plurality of light emitting devices such as lights, lamps, and light emitting elements and light receiving devices such as light receiving sensors and phototubes are arranged to face each other in the vertical direction across the movement locus of the hanger. Each of the first and second arm driving devices controls the front arm or the rear arm by detecting the height of the workpiece by blocking the light irradiated from the light emitting device toward the light receiving device by the workpiece. It is characterized by adjusting the height of the bar. When the work is a painted automobile body or the like, the cleaning member may be made of polynet.

  By configuring in this way, as shown in the attached drawings, the cleaning machine has an arm drive in which the hanger arm 26 on the front side of the hanger 25 that supports a work such as the automobile body 30 is a first and second arm drive device. When approaching the front arm 3F, that is, the front arm of the apparatus 1R, 1L, the bar 5A is moved to the other rear arm 3B, that is, the rear arm.

  According to such a configuration, when the arms 26 and 27 of the hanger 25 come close to the front arm that supports the bar, the bar is replaced with the rear arm of the arm driving device. The front arm of the two-arm drive device does not prevent the hanger 25 from moving.

  In the prior art described in the background art, when the arms 26 and 27 of the hanger 25 are close to the bar 42, the bar 42 and the sheet 41 are controlled to move away from the hanger even during cleaning. It has occurred. On the other hand, according to the present invention, even when the first and second arms supporting the bar are changed, for example, the bar is changed from the front arm to the rear arm at the same position in the air. It will not be done. Therefore, the seat can wipe the surface of the automobile body 30 uniformly from the front of the body to the back of the body.

Hereinafter, based on the drawings, the same reference numerals are used for members that are substantially the same as or correspond to those of the conventional example, and a preferred embodiment of the paint cleaning machine 10 according to the present invention will be described.

The painted cleaning machine 10 includes a pair of arm driving devices 1R and 1L, and the arm driving device 1R and the arm driving device 1L are installed to face each other so as to sandwich the movement trajectory of the hanger 25. Each arm drive device 1R, 1L includes a pair of arms 3F, 3B, respectively. That is, each arm drive device 1R, 1L is arranged on the opposite side in the movement direction along the movement direction of the hanger 25, and the arm 3F as a front arm arranged on the movement direction side along the movement direction of the hanger 25. And an arm 3B as a rear arm.
Furthermore, in the paint cleaning machine 10, the sheet member 5 is horizontally placed between the arm driving devices.
The painted material cleaner 10 according to the present invention is configured to drive and control the arms 3F and 3B so that the sheet member 5 is changed from one arm 3F (3B) to the other arm 3B (3F). Yes.

  As shown in FIG. 2, the sheet member 5 includes a bar 5A and a cleaning member 5B hanging from the bar 5A. Here, as the cleaning member 5B, a mop-like member may be used in addition to the net-like polynet or sheet. As shown in FIG. 1, the total length L1 of the bar is set to about the vehicle width, but the distance L2 between the pair of hanger arms 26, 26 (27, 27) arranged in the lateral direction before and after the hanger 25. Is set shorter.

The pair of arm driving devices 1R and 1L are installed on the work floor side by side in the direction of the width of the hanger 25 of the suspended conveying device 20, that is, the direction perpendicular to the conveying direction of the automobile body 30.
The right arm drive device 1R includes a rectangular parallelepiped box 2R formed of a highly rigid steel material. In addition, a pair of arms 3F and 3B are attached to the box so as to be rotatable in the horizontal direction and movable up and down in the arm driving device 1R.

  Here, first, each arm 3F, 3B is a first member 3F1, 3B1 that extends straight in the horizontal direction, and a second member that extends straight by bending at a right angle in the horizontal direction at the tip of the first member 3F1, 3B1. It consists of members 3F2 and 3B2. The arms 3F and 3B are configured such that the first members 3F1 and 3B1 and the second members 3F2 and 3B2 are integrally joined, and the outer shape is L-shaped.

  In addition, in the arm 3F on the vehicle body conveyance direction side, as shown by the solid line in FIG. 1, the second member 3F2 is in the state where the first member 3F1 extends toward the arm drive devices 1R and 1L facing each other. The front end of the one member 3F1 extends straight in the direction opposite to the conveying direction of the automobile body 30. In contrast to this, in the arm 3B on the rear side in the conveyance direction of the automobile body 30, the second member 3B2 extends straight in the conveyance direction of the automobile body 30, as indicated by a dotted line in FIG.

  Further, as shown in FIG. 3, the second member 3F2, 3B2 of each arm 3F, 3B is formed with a recess 5C as a receiving portion for receiving the bar 5A, and each arm 3F, 3B The bar 5A can be supported by placing the bar 5A on the bottom surface 5C1 of the recess 5C of the members 3F2 and 3B2. When the bar 5A is formed in, for example, a circular cross section, the rolling of the bar 5A is restricted by the side surfaces 5C2 and 5C3 of the recess 5C.

  Further, the arms 3F and 3B, that is, the base portions of the first members 3F1 and 3B2, are fixed to the columns 4F and 4B. The support columns 4F and 4B extend in the vertical direction and are attached to the box 2R. The pair of support posts 4F and 4B to which the arms 3F and 3B are fixed are arranged so as to be aligned along the conveyance direction of the automobile body 30.

  And the support | pillar 4F by the side of a vehicle body conveyance direction is equipped with arm drive apparatus 1R so that rotation is possible and it can move up and down. For example, although not shown, the column 4F formed in a columnar shape is supported by the box 2R, and the lower part of the column 4F is accommodated in the box from the opening formed in the upper end surface of the box 2R, and the upper part of the column 4F is Projects out of the box. In addition, the arm 3F is fixed to the upper part of the support | pillar extended out of the box.

  Further, although not shown in the figure, teeth are cut around the lower surface of the support column 4F accommodated in the box, and a gear connected to the rotation shaft of the motor meshes with the teeth on the support surface. With such a meshing configuration, the support 4F can be rotated by driving a motor, and the arm 3F fixed to the support 4F can be rotated in the horizontal direction.

  As shown by the solid line and the dotted line in FIG. 1, the arm 3F is attached to the box 2R so as to be rotatable within a range of a rotation angle of about 90 degrees, and a motor for rotating the arm 3F includes, for example, An optical encoder is attached, and the detection signal is sent to the control device 8 (see FIG. 4 described later) in the box, and the rotation of the arm 3F can be controlled.

  Moreover, although illustration is abbreviate | omitted, for example, the piston of the hydraulic type or pneumatic pressure which moves up and down is installed under the support | pillar 4F, a piston is driven by the control apparatus 8, and the arm 3F raises or falls.

  Thus, the motor and piston for driving the vehicle body conveyance direction side support column 4F are provided in the box separately from those for the front support column so as to individually drive the rear support column 4B.

  As shown in FIG. 1, the distance L3 between the front column 4F and the rear column 4B is equal to the first member 3F1 of the front arm 3F indicated by a solid line and the rear side indicated by a dotted line. The distance interval may be such that the arms 26 and 27 of the hanger 25 can enter the space S between the first members 3F1 and 3B1 in a state where the first member 3B1 of the arm 3B is parallel.

  Further, the lengths of the first members 3F1 and 3B1 of the respective arms 3F and 3B in the right arm drive device 1R are set to be long for the front arm 3F and short for the rear arm 3B. In this case, the lengths of the arms 3F and 3B need to be set in relation to the positions of the arms 3F and 3B and the arms 26 and 27 of the hanger 25.

  For example, as described above, first, the bar 5A, to which the cleaning member 5B is attached, is set shorter than the interval L2 between the pair of hanger arms 26, 26 (27, 27) arranged side by side before and after the hanger 25, The length of the rear arm 3B is set so that the end of the bar 5A can be supported by the second member 3B2, and the second member 3B2 of the rear arm 3B is in contact with the bar 5A. The length of the front arm 3F may be set so that the second member 3F2 of the front arm 3F abuts at a position inside the bar (see the drawing). Although the configuration example in which the front arm 3F is lengthened and the length of the rear arm 3B is shortened as described above is shown, conversely, the rear arm 3B is lengthened and the front arm 3F is shortened. May be.

  Furthermore, in the arm drive device 1R according to the embodiment of the present invention, the sensor 6 that detects the arms 26 and 27 of the hanger 25 is attached to the first member 3F1 of the arm 3F. In addition, as shown in FIG. 1, the sensor 6 is on the surface of the first member 3F1 intersecting the moving direction of the arms 26 and 27 of the hanger 25 in a state where the first member 3F1 extends in the direction crossing the vehicle body conveying direction. It is attached. As the sensor 6, a microswitch that can detect contact with the hanger 25 can be used.

  As the arms 26 and 27 of the hanger 25 abut on the sensor 6, the arm driving device 1R uses the contact between the hanger arms 26 and 27 and the arm 3F as a trigger, as described later, the bar 5A from the arm 3F. Switch to the other arm 3B.

  When the sensor 6 detects the arms 26 and 27 of the hanger 25, a detection signal is sent to the control unit 50 of the suspended conveyance device 20 as shown in FIG. 4. When the sensor 6 detects the hanger 25, the control unit 50 controls the suspended conveyance device 20 to stop the movement of the hanger 25.

The right arm drive device 1R is configured in this way, but the left arm drive device 1L is configured in the same manner.
Thus, by configuring the painted material cleaner 10 according to the embodiment of the present invention, the left and right arm drive devices 1R and 1L are installed facing each other so as to sandwich the movement trajectory of the hanger 25, and the sheet member 5 The right end is supported by any arm 3F, 3B of the right arm drive device 1R, and the left end is supported by any arm 3F, 3B of the left arm drive device 1L. It is horizontally mounted between the driving devices 1R and 1L.

  By the way, in the sedan type automobile body 30, for example, the roof is located higher than the hood at the front of the vehicle, and the rear part of the vehicle behind the roof is located lower than the roof. There is a height difference of “Low” → “High” → “Low”. Therefore, the height of the sheet member 5 that wipes the surface of the automobile body may be made variable according to the height difference of the automobile body.

Therefore, in the painted object cleaner 10 according to the embodiment of the present invention, as shown in FIG. Sensors and photoelectric tubes 9 are installed. And the light irradiated toward the photoelectric tube 9 from a lamp or the like is blocked by the automobile body 30 conveyed by the hanger 25, so that the position of the automobile body can be detected. The detection signal is sent to the control device 8 in the box, and the control device 8 drives the piston to raise or lower the arm 3F.
Specifically, a plurality of light emitting devices such as lights, lamps, and light emitting elements and light receiving devices such as light receiving sensors and photoelectric tubes are arranged opposite to each other in the vertical direction across the movement locus of the hanger 25, The height of the workpiece is detected when the light irradiated from the light emitting device toward the light receiving device is blocked by the workpiece. Thereby, each 1st and 2nd arm drive device controls a front arm or a rear arm, and makes it adjust the height of a bar.

  Note that the “effective zone” described in FIG. 5 is the movable range of the bar 5A. In order to change the height of the bar 5A within this movable range, a plurality of photoelectric tubes 9 are used. Four phototubes 9 are arranged in the vertical direction at a position close to the height position. The “effective zone” is set in advance depending on the vehicle type.

Next, operation | movement of the paint cleaning machine 10 which concerns on embodiment of this invention is demonstrated.
As shown in FIG. 1, the painted object cleaner 10 normally supports the bar 5 </ b> A with the arms 3 </ b> F of the left and right arm driving devices 1 </ b> R and 1 </ b> L, and the cleaning member 5 </ b> B hanging from the bar 5 </ b> A Abut. Then, the automobile body 30 is moved forward by the suspension conveyance device 20 in a state where the cleaning member 5B and the automobile body 30 are in contact with each other. Therefore, as the automobile body 30 moves, the cleaning member 5B sequentially wipes dust such as dust attached to the body surface extending from the front of the body to the rear of the body.

  Further, the height difference of the automobile body is detected by the light sensor or the phototube 9, and the control device 8 drives the piston so that the arm 3F is raised or lowered. The bar 5A is supported at a desired height position within the effective range shown in FIG. 5, and the cleaning member 5B comes into contact with the surface of the automobile body to wipe off dust.

  In the middle of such a cleaning operation, the painted object cleaner 10 performs a transfer operation of the bar 5A. In the following description, a case will be described in which the front hanger arm 26 of the hanger 25 is close to the front arm 3F of the left and right arm driving devices 1R and 1L.

  When the sensor 6 installed on the front arm 3F of each of the left and right arm driving devices 1R and 1L detects the arm 26 of the hanger 25, the control device 8 in the box is switched so that the bar 5A is replaced with the rear arm 3B. Pistons and motors are driven and controlled to rotate and move the arms 3F and 3B up and down.

  In the state where the hanger 25 is stopped, the drive control of the arm for changing the bar 5A from the front arm 3F to the rear arm 3B is performed. At this time, the detection signal of the sensor is also sent to the control unit 50 of the suspended conveyance device 20, and the control unit 50 temporarily stops the conveyance of the automobile body 30, that is, temporarily moves the hanger 25. Stop.

  As a procedure for changing the bar 5A, first, with the front arm 3F supporting the bar 5A, the first member 3B1 of the rear arm 3B is parallel to the first member 3F1 of the front arm 3F. The rear arm 3B rotates. Then, with the first members 3F1 and 3B1 of the front and rear arms 3F and 3B being parallel, the rear arm 3B is raised, and the end of the bar 5A is placed in the recess formed in the second member 3B2. Accommodate. When the bar 5A is accommodated in the recess 5C of the rear arm 3B, the front arm 3F is lowered, and then the front arm 3F is rotated to the position indicated by the dotted line in FIG. 1 so as not to hinder the movement of the hanger 25. .

  In this way, the left and right arm driving devices 1R and 1L change the bar 5A from the front arm 3F to the rear arm 3B. Note that the time required to change the bar 5A from one arm 3F to the other arm 3B is about 10 seconds.

  When the transfer work is completed, a work completion signal is sent from the control device 8 in the box to the control unit 50 of the suspending and conveying device 20, and the control unit 50 causes the hanger 25 that supports the automobile body 30 to move a predetermined distance. The suspended conveyance device 20 is controlled so as to move forward.

  Here, as a position where the hanger 25 has moved forward by a predetermined distance, for example, the front hanger arm 26 of the hanger 25 holding the automobile body 30 is the front arm 3F of each of the left and right arm driving devices 1R, 1L. It is a position far from where it does not interfere with. In other words, the hanger arm 26 on the front side of the hanger 25 is connected to each arm driving device 1R, 1R, 1L so that the bar 5A can be changed from the rear arm 3B to the front arm 3F in the left and right arm driving devices 1R, 1L. It suffices to be at a position deviated from the movement locus of the 1 L front arm 3F.

  When the control unit 50 moves the hanger 25 forward by a predetermined distance, the control unit 50 temporarily stops the movement of the hanger 25 again. At this time, the control unit 50 sends a signal to the left and right arm drive devices 1R and 1L in order to notify that the movement of the hanger 25 has been stopped.

  When each arm driving device 1R, 1L receives the hanger stop signal from the control unit 50, the arm driving devices 1R, 1L drive and control the arms 3F, 3B so that the bar 5A is switched from the rear arm 3B to the front arm 3F. . In this case as well, the control device 8 in the box drives and controls the pistons and motors to rotate and move the arms 3F and 3B in the same manner as described above.

  As the change-over procedure, first, each arm driving device 1R, 1L rotates the front arm 3F to the lower side of the bar 5A and then raises the front arm 3F. Then, the rear arm 3B is lowered and rotated to return to the original position. In this way, the bar 5A is changed over so that it is supported by the front arm 3F of each of the left and right arm driving devices 1R, 1L.

  Thus, the paint cleaning machine 10 returns to the normal state. That is, the bar 5A is supported by the front arms 3F and 3B of the left and right arm drive devices 1R and 1L, and returns to the state of being laid between the arm drive devices 1R and 1L.

  When the transfer work is completed, a work completion signal is sent from the control device 8 in the box to the control unit 50 of the suspended transfer device 20, and the control unit 50 moves the hanger 25 supporting the automobile body 30 forward. In this way, the suspended conveying device 20 is controlled.

In this way, when the hanger arm 26 on the front side of the hanger 25 that supports the automobile body 30 comes close to the hanger arm 3F on the front side of each arm driving device 1R, 1L, the painted cleaning machine 10 Change the bar 5A to the hanger arm 3B.
When the hanger 25 moves forward a predetermined distance, the bar 5A is again transferred from the rear arm 3B to the front arm 3F.

  In the above description, the operation example of the paint cleaner 10 when the front hanger arm 26 of the hanger 25 is close to the front arms 3F and 3B of the arm drive devices 1R and 1L has been described. Even when the hanger arm 27 on the rear side of the hanger 25 comes close to the arm 3F on the front side of the 1R, 1L, the arm 3F, 3B that supports the bar 5A is changed in each arm driving device 1R, 1L.

  As described above, according to the painted object cleaner 10 according to the embodiment of the present invention, when the arms 26 and 27 of the hanger 25 approach the front arm 3F that supports the bar 5A, the bar is moved to the rear arms 26 and 27. Since they are changed, the arms 3F of the left and right arm driving devices 1R and 1L that support the bar do not hinder the movement of the hanger 25.

In the prior art described in the background art, when the arms 26 and 27 of the hanger 25 are close to the bar 42, the bar 42 and the sheet 41 are controlled to move away from the hanger even during cleaning. It has occurred. On the other hand, according to the painted material cleaning machine 10 according to the embodiment of the present invention, even when the arms 3F and 3B supporting the bar 5A are replaced, for example, the bar 5A has one arm at the same position in the air. Since it is transferred from 3F (3B) to the other arm 3B (3F), the cleaning is not interrupted.
Thus, according to the painted object cleaner 10 according to the embodiment of the present invention, the cleaning member 5B can wipe the surface of the automobile body 30 uniformly from the front of the body to the rear of the body.

The present invention can be implemented in various forms without departing from the spirit of the present invention. For example, in the above description, the case where the workpiece cleaned by the paint cleaning machine 10 is the automobile body 30 is taken as an example. However, the workpiece is not limited to the automobile body 30 and may be a door, a hood, or the like. It is clear that it is good.
