Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 5. Note that in FIGS. 1 to 5, the same parts as in FIG. 6 are given the same reference numerals, and detailed explanation thereof will be omitted.

As shown in FIG. 1, the vehicle window glass assembling apparatus in this embodiment includes a silk conveyor 1, a windshield transfer device 5, and an automatic operation system that is combined with the silk conveyor 1. It is composed of a mechanism 9. The automatic operation mechanism 9 described above has two robots 10.11, a first and a second, arranged along the side of the silk conveyor 1, and is arranged corresponding to these robots 10.11. 1st and 2nd
It consists of two centering jigs 1.2.13, a window glass transfer machine 14, and a window glass transport machine 4, and the above-mentioned first and second robots 10.11 move the vehicle window glass 6. It is configured to have both the function of automatically replacing several types of tools required for assembly to the vehicle body and the function of transporting the window glass 6. In addition, as a tool, as shown in FIGS. 2 to 5, a suction tool 16. Wipe tool 17. Primer application tool 18. A urethane coating tool 19 is prepared in a tool box (not shown).

Further, in FIG. 1, reference numeral 15 denotes a work instruction sensor provided in connection with the cotton conveyor 1.

Next, the operation of the assembly apparatus of this embodiment will be described.

First, in the first step, the suction tool 16 equipped with the air hose 20 is attached to the tool holder sections 10a and 11a (see FIGS. 2 and 5) of the first and second robots 10.11, respectively. Then, one window glass 6 is removed from the cart 7 by the suction tool 16 of the first robot IO.
As shown in the figure, it is taken out by suction and placed in a predetermined position on the first centering jig 12. After the window glass 6 is set on the first centering jig 12 in this way, the first robot 10
Suction tool 1 attached to the tool holder part 10a of
6 is automatically removed, and the wipe tool 17 is automatically attached to the tool holder portion 10a as shown in FIG.

Then, the peripheral edge of the window glass 6 set on the first centering jig 12 is cleaned with the wipe tool 17. After that, the tool holder part 10a of the robot lO
The wipe tool 17 attached to the window is automatically replaced with the primer application tool 18, and the tool 18 applies the primer 2 onto the peripheral edge of the windshield 6, as shown in FIG.

Next, a suction tool 16 attached to the tool holder part 11a of the second robot 11 moves the window glass 6 coated with the brimer from the first centering jig 12 to a predetermined position on the second centering jig 13. It is transferred to and converted into cents. Then, this second centering jig 1
Windshield 6 is detected by a position sensor (not shown) installed at 3.
As the suction tool 16 is automatically removed and the urethane coating tool 19 is automatically attached to the tool holder portion 11a, as shown in FIG. As shown, the urethane 22 is brought into contact with the peripheral edge of the window glass 6 using this tool 19. Applied as a glue.

After the application of urethane 22 is completed, the tool of the second robot 11 is replaced, and the suction tool I6 is automatically attached again to the tool holder portion 11a, and this tool 16 picks up the window glass 6 coated with urethane. It is carried from above the centering jig 13 of No. 2 to the window glass transfer machine 14 and sent to the window glass conveyance machine 4. Then, the windshield 6 sent to the conveyor 4 is transported to the window glass transfer device 5 in synchronization with a detection signal from the work instruction sensor 15 that detects the vehicle body flowing on the clear cover conveyor l, and is transferred to the clear cover conveyor 1. It is assembled to the door, roof, etc. of the vehicle body being transported at step 1.

Note that while the second robot 11 is working, the first robot 10 continues the above-mentioned work without stopping.
At the time when the second robot 12 carries the window glass 6 to the transfer machine 14, the succeeding window glass 6 is always stocked on the second centering jig 13. Therefore,
The first and second robots 10 and 11 operate without waiting time.

According to the window glass assembling device having such a configuration, only the first and second two robots 7 and 10, 11 need to be placed on the side of the cotton conveyor 1, so it is less expensive than the conventional case. This makes it possible to reduce the number of robots and thus equipment costs, and also facilitates installation of the device even in a narrow space. Moreover, the first robot lO has a suction tool 16.
Since the wipe tool 17 and the brimer coating tool 18 are configured to perform different tasks, and the second robot 11 is configured to perform different tasks with the suction tool 16 and the urethane coating tool 19, the robot operation rate is low. will improve. Furthermore, the first and second robots 10
．． 11 is also provided with the function of conveying the window glass 6, so the window glass coating conveyor 2 (see Fig. 6) that was conventionally used is no longer necessary.
It is possible to further reduce equipment costs and save space.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, the number of robots is not limited to two, but can be one as needed.
It is possible to change to one or three units. Also, tools 16 to 19
The order in which robots are replaced and the division of work for robots (10.11) can be changed as appropriate.

C1 Effects of the Invention As described above, the present invention provides an I! that is capable of automatically replacing several types of tools in a windshield assembly robot placed in correspondence with a vehicle clearing conveyor. Since the system is equipped with a function to transport wind glass and wind glass, it is possible to reduce the number of robots and reduce equipment costs, and eliminates the need for a coating conveyor to transport window glass to each robot. Therefore, together with the reduction in the number of robots, it is possible to save space for installing the device. Moreover, since one robot performs multiple types of work, the waiting time (non-operating time) of each robot can be eliminated, and the robot operating rate can be greatly improved.
