[0065] Based on the measurement result input from the sensor controller 84, the first robot controller 82 determines whether the installation position of the sash S is within a predetermined tolerance range, whether the V is out of the tolerance range. It is configured to determine When the first robot controller 82 falls outside the predetermined tolerance range, the first robot controller 82 moves the installation position of the sash S into the predetermined tolerance range based on a predetermined program and data stored in advance about the sash S. The corrective amount to be stored is obtained, and based on this correction amount, the robot arms 20a, 21a of the first and second correction robots 20, 21 are deformed so that the sash S is deformed by the deformation amount obtained. The amount of movement is determined. The movement amount for the second correcting robot 21 obtained by the first robot controller 82 is output to the line control panel 81, and is input from the line control panel 81 to the second robot controller 83. Yes. Then, the correcting robots 20 and 21 are operated by the first and second robot control devices 82 and 83. The line control panel 81, the first robot control device 82, and the second robot control device 83 constitute a control unit.

Next, the case where the sash S of the left door D1 and the right door D2 is corrected by the correction device 1 configured as described above will be described. The door hinge H is fastened and fixed to the left door D1 transported to the first support base 10 and the door hinge H is fastened and fixed to the right door D2 transported to the second support base 10 as well.

[0067] The left door D1 is transferred to the left door jig Y1 by the first door transfer robot 12, and is held by the jig Y1. This is a door conveyance process. The left door jig Y1 is positioned by the nutrunner 77 provided on the second straightening attachment 76 of the second straightening robot 21 after positioning the left door D1 and the positioning pin P by the positioning mechanism 44. Fasten and fix pin P. This is the positioning pin fixing step. After that, the positioning mechanism 44 is released. After the positioning pin fixing step, the right door D2 supported by the second support 11 is transported to the right door jig Y2 by the second door transport robot 13, and is held by the jig Y2. . [0068] Thereafter, as shown in the flowchart of FIG. 11, the sash S of the left door Dl is corrected. First, the left door D1 is fixed while being positioned by the front and rear fixing mechanisms 42, 43 of the left door jig Y1. This is the door fixing process. Then, in step SA1 after the start of the flow chart, the first and second sash building position measurement sensors 50 and 51 are turned on, and the first and second measurement surfaces of the sash S are irradiated with laser light. The measurement result is input to the first robot controller 82 via the sensor controller 84, and the first robot controller 82 can obtain the installation position of the sash S. This is the sash installation position measurement process. When the installation position of the sash S is obtained, the sensors 50 and 51 are turned off. In the following step SA2, the first robot controller 82 determines whether the installation position of the sash S is within the predetermined tolerance range, and whether it is out of the tolerance range! If YES in step SA2, the process proceeds to step SA3 and the robot arms 20a and 21a of the first and second straightening robots 20 and 21 are moved to the left. Set robots 20 and 21 to their original positions so that they do not interfere with door D1. In subsequent step SA4, it is determined that the installation position of the sash S of the left door D1 is acceptable, and a pass signal is output to the line control panel 81 together with the identification number of the left door D1.

[0069] In step SA2, if the installation position of sash S is out of the predetermined tolerance range and it is determined as NO, the process proceeds to step SA5, and first robot controller 82 determines the installation position of sash S. The robot arm 20a of each of the first and second straightening robots 20 and 21 is obtained so that a correction amount for obtaining a predetermined tolerance range is obtained and the sash S is deformed by the deformation amount obtained based on the correction amount. The amount of movement of 21a is determined. Thereafter, the process proceeds to step SA6, and before the sash S is corrected, the first and second correction robots 20 and 21 move the first and second correction attachments 65 and 76 to the correction origin. When the first correction attachment 65 is at the correction origin, as shown in FIG. 8, the rear portion of the upper edge of the sash S is positioned between the inner correction head 70 and the outer correction head 71. . When the second straightening attachment 76 is at the straightening origin, as shown in FIG. 9, the middle portion in the front-rear direction at the upper edge of the sash S is positioned between the inner straightening head 70 and the outer straightening head 71. ing.

[0070] Thereafter, the process proceeds to step SA7, where the first and second straightening robots 20 and 21 Perform correction work. This is the sash correction process. This correction work will be explained in detail. Depending on the installation position of the sash S, for example, the rear part of the sash S may be deformed to the passenger compartment side and the middle part in the front-rear direction may be deformed to the vehicle exterior side. In this case, the first straightening attachment 65 of the first straightening robot 20 is moved toward the passenger compartment side of the left door D1, and the outer straightening head 71 is brought into contact with the outer surface (contacting surface) of the sash S. Let At this time, since the outer correction head 71 moves along the contact surface of the sash S, the outer correction head 71 can be brought into contact with the contact surface of the sash S in a stable state. At the same time, the second straightening attachment 76 of the second straightening mouth bot 21 is moved toward the vehicle exterior of the left door D1, and the inner straightening head 70 is brought into contact with the vehicle inner surface of the sash S. Both attachments 65, 76 force By moving the deformation amount set by the first robot controller 82, different deformation forces act on the rear and middle portions of the sash S, and the sash S is deformed. Depending on the installation position of the sash S, only one of the correction attachments may be moved, or both of the correction attachments may be moved in the same direction. Further, the movement amount of the first correction attachment 65 and the movement amount of the second correction attachment 76 may be the same or different.

[0071] When the first correction work is completed, the process proceeds to step SA8, where the first and second sash building position measuring sensors 50 and 51 are turned on. In the subsequent step SA9, the sash is moved in the same manner as in step SA2. It is judged whether the installation position of S is within the specified tolerance range, out of tolerance range. This is the installation position confirmation process. As a result of the second determination, if it is determined that it is within the tolerance range of YES, the process proceeds to steps SA3 and SA4.

[0072] On the other hand, when the installation position of sash S is out of the predetermined tolerance range and is determined to be NO in step SA9, the process proceeds to step SA10, and in the same way as in step SA5, the first and second corrections are performed. The amount of movement of each robot arm 20a, 21a of the robot 20, 21 is determined. Then, go to Step SA11 and perform the second correction work as in Step SA7.

[0073] When the second straightening operation is completed, the process proceeds to step SA12, where the first and second sash building position measuring sensors 50 and 51 are turned on, and in step SA13, as in step SA2, the sash S It is judged whether the installation position is out of the force and tolerance range within the specified tolerance range. As a result of this third determination, it is determined that the value is within the tolerance range of YES. If determined, go to steps SA3 and SA4.

[0074] On the other hand, in step SA13, if the installation position of sash S is out of the predetermined tolerance range and the determination is NO, the process proceeds to step SA14, and the first and second straightening robots 20 are the same as in step SA5. , 21 determines the amount of movement of each robot arm 20a, 21a, proceeds to step SA15, and performs the third correction work. Thereafter, the process proceeds to step SA16, where the first and second sash building position measuring sensors 50 and 51 are turned ON, and the first and second straightening robots 20 and 21 are set to their original positions.

[0075] Then, the process proceeds to step SA17, and in the same manner as in step SA2, it is determined whether the installation position of the sash S is within a predetermined tolerance range or out of the tolerance range. As a result, if it is determined that it is within the tolerance range of YES, the process proceeds to Step SA4.

[0076] On the other hand, if it is determined in step SA17 that the installation position of sash S is out of the predetermined tolerance range, the process proceeds to step SA18, and the line control panel 81 is informed with the identification number of the left door D1. Outputs a pass signal. This left door D1 can be extracted on the downstream side of the door production line.

[0077] When the correction operation is completed as described above, the fixing mechanisms 42 and 43 of the left door jig Y1 are released, and the left door D1 is gripped and carried out by the carrying-out robot 22. This is the unloading process. When the unloading process is completed, the left door D1 to be corrected next is newly transported and held by the left door jig Y1.

[0078] On the other hand, the right door D2 includes the left door D1 and the left door D1 based on the installation position of the sash S obtained by the first and second sash installation position measuring sensors 50 and 51 of the right door jig Y2. Similarly, the sash S is corrected by the first and second correction robots 20 and 21. At this time, the straightening unit 67 is attached to the robot arms 20a and 21a of the first and second straightening robots 20 and 21, so that the robot 20 and 21 can be positioned to match the shape of the sash S of the right door D1. Move to. As a result, the same robots 20 and 21 and the straightening unit 67 can perform straightening work on the sash S of different types of doors Dl and D2. Note that the positioning pin P is also fastened and fixed in the right door D1. In the first embodiment, the jig device 15 is provided with the left door jig Y1 and the right door jig Y2, so the sash S of the left door D1 is corrected and the right door D2 is conveyed. It is also possible to perform the work in parallel. [0079] Next, in the case where the door manufactured on the door manufacturing line is changed to the front left door D1 and the right door D2 with the rear left door and the right door (not shown), FIG. This will be described based on the flowchart shown. When the door type is changed, first, a door type change signal is output from the line control panel 81 at step SB1. As a result, the first and second door transfer robots 12 and 13 and the first and second correction robots 20 and 21 are switched to the door type change mode. This is the first mode switching step. After that, remove the jigs Yl and Υ2 currently fixed to the jig frame 33 and replace them with the jigs (not shown) corresponding to the next door.

[0080] First, before removing the left door jig Y1 and the right door jig Υ2 from the jig frame 33, in step SB2, the first correction robot 20 performs the first adjustment of the left door jig Y1. Remove the first and second sash building position measuring sensors 50 and 51 and the first and second sash building position measuring sensors 50 and 51 of the right door jig Υ2 one by one. In other words, the first robot controller 82 that has received the door type change signal moves the first straightening feature 65 by the first straightening robot 20 and, as shown in phantom lines in FIG. After 74 is inserted into the cylindrical member 58 of the holding portion 56, the movable claw 74a is protruded and engaged with the engaging portion 58a. When the insertion portion 74 is inserted into the cylindrical member 58, the stop position of the robot arm 20a is slightly shifted so that the insertion portion 74 can be inserted deeper than the target position. By contracting, the cylindrical member 58 is easily moved in the insertion direction of the insertion portion 74. As a result, it is possible to prevent damage that is difficult to apply an excessive force to the holding portion 56 and the like.

[0081] After engaging the movable claw 74a with the engaging portion 58a and then releasing the coupling state of the auto tool changer 55, the first sash installation position measuring sensor 50 and the attaching / detaching bracket 54 together with the left door jig Y1 Detach from the main body part 40. The first sash building position measuring sensor 50 is held by the holder 61 of the jig frame 33. In this way, the four sash mounting position measuring sensors 50 and 51 are removed in order and held in the holder 61. This is the sensor storage process. Thereafter, the process proceeds to step SB3, and the robot arms 20a and 21a of the first and second straightening robots 20 and 21 are moved to a non-interference position where the jigs Yl and Υ2 to be replaced do not interfere.

[0082] Next, the process proceeds to step SB4. In this step SB4, first, the first door transfer robot As shown in Fig. 4, after the robot side adapter 19a attached to the tip of the robot arm 12a of the first door transfer robot 12 is coupled to the adapter 30b of the left door jig Y1, the jig adapter Release the coupling of 36b and remove the left door jig Y1 from the jig frame 33. The left door jig Y1 is transported to the first jig storage stand 17 and held on the stand 17. This is the jig storing step.

[0083] After that, the hole 29a of the pin engaging portion 29 attached between the tip of the robot arm 12a and the robot side adapter 19a of the auto tool changer 19 is inserted into the first jig storage stand. The stand 17 is rotated by being engaged with the pin 25a of 17 and pulled or pushed, and the jig corresponding to the type of the next door is brought to the position facing the first door transfer robot 12. Then, after being attached to the tip of the robot arm 12a of the first door transfer robot 12, the robot side adapter 19a is coupled to a jig adapter (not shown) corresponding to the next door, The jig is removed from the stand 17 and conveyed to the jig frame 33, and the adapter 36 a of the jig frame 33 is coupled and fixed to the jig frame 33. This is the jig installation process. When replacing the right door jig Y2, the second door transfer port bot 13 is used in the same manner. After replacing the jig Y1, the robot side adapter 19a attached to the tip of the robot arms 12a and 13a of the first and second door transfer bots 12 and 13 is connected to the tool side of the door support attachment 26. Join the adapter.

[0084] Thereafter, the process proceeds to step SB5, where the four sash building position measuring sensors 50 and 51 held in the holder 61 are held in order by the first correcting robot 20, and then transported to a new jig. Fix it. This is the sensor mounting process. After attaching the sash building position measuring sensors 50, 51, the process proceeds to step SB6, and the mouth bot arms 20a, 21a of the first and second straightening robots 20, 21 are moved to their original positions. The line control panel 81 then switches the first and second door transfer robots and the first and second correction robots 20 and 21 to the next door sash correction mode. This is the second mode switching step.

[0085] After replacing the jig Y in this way, the sash correction of the rear door is performed in the same manner as the front doors Dl and D2. The shape of the sash of this rear door is different from the shape of the sash of the front doors Dl and D2. The force of the first and second straightening robots 20 and 21 By moving the robot arms 20a and 21a, it is possible to move the correction attachments 65 and 76 to a position that matches the shape of the sash S. This makes it possible to easily and quickly change the position of the correction unit 67 using the robots 20 and 21 without removing the correction unit 67 in the door manufacturing line of the multi-mix production system. Furthermore, by changing the position of the corrector 67 attached to the robot arm 20a, 2 la in this way, it is not necessary for the operator to check and check the changed position.

As described above, according to the correction apparatus 1 according to the first embodiment, the correction attachments 65 and 76 are attached to the robot arms 20a and 21a of the correction robots 20 and 21, and the robot 20 21 is used to correct sash S, so that the position of the correction part 67 can be easily and quickly adapted to different types of doors Dl and D2 in a multi-mix production door production line. Manufacturing man-hours for doors Dl and D2.

[0087] Since the left door jig Y1 and the right door jig Y2 are fixed to the jig device 15, for example, the sash S of the left door D1 fixed to the left door jig Y1 is corrected. During this time, the right door D2 can be transported and fixed to the right door jig Y2, and preparations for correction can be made in parallel. As a result, the number of manufacturing steps for the doors Dl and D2 can be further reduced.

[0088] Further, since the first and second straightening robots 20 and 21 are disposed behind and in front of the left door D1, both sides of the sash S in the front-rear direction can be straightened simultaneously.

[0089] In addition, the sash building position measuring sensors 50 and 51 can be attached to the jigs Yl and Υ2 so that they can be attached and detached. Therefore, even if the type of the doors Dl and D2 changes, Position measuring sensors 50 and 51 can be used, and the cost of the sash correction device 1 can be reduced.

[0090] In addition, the first fixing robot 20 can be used to fasten and fix the positioning pin Υ of the door hinge まま while the doors Dl and D2 are fixed to the jig Yl and Υ2. This can save labor at the work site.

[0091] When the types of doors Dl and D2 to be manufactured are different, the jig Y can be automatically replaced by the first and second door transfer robots 12 and 13, thereby further saving labor. be able to.

[0092] Further, when the sash S is corrected, the outer correction head 71 can be moved along the contact surface of the sash S, so that the outer correction head 71 contacts the outer surface of the sash S. It is possible to suppress damage such as dents.

[0093] Also, the positioning pin P of the door hinge H is fastened and fixed, the sash S is straightened, the result is confirmed, and each process from the doors Dl and D2 being carried out is carried out as one straightening station T. Can be implemented. This can reduce the number of stations on the door production line.

[0094] Further, since the first and second sash building position measuring sensors 50, 51 are non-contact type, the sensors 50, 51 do not hit the sash S during measurement. Can be prevented.

In the first embodiment, two jigs Yl and Υ2 are fixed to the jig frame 33. However, only one jig Υ is fixed to the jig frame 33. Or you can fix three or more.

[0096] Further, the fastening operation of the positioning pin 位置決め of the door hinge Η may be performed at another station. In this case, the jig Yl, the positioning mechanism 44 of the rod 2 and the nut runner 77 of the correction attachment 76 can be omitted.
