Further, the front connection frame 12 is provided with an air balance device 60 for bringing the holding device 20 into contact with the lifting / lowering guide device 22 from below. The air balance device 60 includes a mounting bracket 61 provided at the center of the front connection frame 12 and a balance hoist 62 mounted on the lower surface of the mounting bracket 61. The cable 63 is fixed to the mounting frame 41, and the cable 63 is allowed to act freely.

The front connection frame 12 is provided with a hanger device 70 for preventing the front window glass C from falling from the holding layer 20. That is, the hanger device 70 is divided back and forth, and the left and right rotating shafts 72 attached to the front connection frame 12 via the bearings 71 and the plurality of (two left and right) rotating shafts 72 are continuously provided downward. A vertical rod 73, a receiving member 74 continuously provided in a direction opposite to the lower end of the vertical rod 73,
It comprises an air cylinder device 76 provided between the lever 75 from 72 and the front connection frame 12 and the like.

The air pipe 47 of the air supply device 21 communicates with the air balance device 60, the air cylinder device 76, and the like.

Below the fixed path A, a transfer path B for transferring a vehicle body (an example of a body to be assembled) E of an automobile is formed. The main body E is transported at a constant speed by a conveyor device (not shown) using a cart or the like, so that the operator can freely ride on the conveyor device.

Next, the operation of assembling the window glasses C and D with the vehicle body E in the above embodiment will be described. On the transport path B, the vehicle body E is transported at a constant speed. Then, as shown by the solid lines in FIGS. 1 and 2, the window glass C,
The self-propelled body 5 holding D is supported on the rail 1 by the plurality of traveling wheel bodies 9 by operating the traveling drive unit 15 to forcibly rotate the traveling wheel body 9, and a plurality of lateral deflection preventions. The vehicle travels in synchronism with the vehicle body E in a state in which the lateral deflection is prevented by the use roller 10. The power to the self-propelled body 5 is
This is performed by the current collector 16 slidingly contacting the power supply device 4.

At the time of such conveyance, in the elevating guide device 22, the operating rod 53 of the power cylinder 52 protrudes, and the support shaft 24 is rotated via the lever 55 to move the second arm 30 upward. As a result, the left-right axis 28 moves to the ascending limit, and the roller follower 26 rolls forward in the guide rail 25.
The arm 27 is horizontal at the raised position, and furthermore, the rail member 32 is also horizontal at the raised position by raising the left-right pin 31 and moving the third arm 34 integrally with the second arm 30. Become.

The balance hoist 62 of the air balance device 60 operates in three stages.
63 is pulled most strongly, so that the guided device 40 is inserted into and brought into contact with the guide member 35, thereby integrating the holding device 20 with the lifting / lowering guide device 22.

Further, the receiving members 74 of the hanger device 70 are engaged with the window glasses C and D held by the vacuum pad 42. In other words, the elongation of the air cylinder device 76 causes the vertical rod 73 to swing toward the opposite side via the lever 75 and the rotating shaft 72, and engages the receiving member 74 with the window glasses C and D. As a result, the traveling body 5 travels in synchronization with the vehicle body E while safely holding the pair of window glasses C and D.

To assemble the window glasses C and D with respect to the vehicle body E, first, the worker on the conveyor device presses the work button to switch the balance hoist 62 to the second-stage operation, that is, the rope body 63 to the weak pulling operation. . Before or after this, the hanger device 70 is released. This causes the air cylinder device 76 to contract, the vertical rod 73 to open as shown by the imaginary line in FIG. 1, and the receiving member 74 to be pulled out of the window glasses C and D.

Next, the elevation guide device 22 is operated to lower the holding device 20. That is, the operating rod 53 of the power cylinder 52 is contracted, and the support shaft 24 is
Move 30 down. Then, the left-right axis 28 moves to the lower ascending limit, and the roller follower 26 rolls backward in the guide rail 25, so that the first arm 27 becomes drooping, and the left-right pin 31 goes up and down. By moving the third arm 34 integrally with the second arm 30, the rail member
32 is lowered and the front end is inclined as low as possible.
The inclination angle at this time is as shown by the imaginary line in FIG.
It is set so as to follow the mounting angles of the window glasses C and D with respect to the vehicle body E.

Further, as described above, since the balance hoist 62 has a weak pulling action (second-step action), the cable body 63 can be smoothly pulled out freely, and further, the contact of the guided body 40 with the guide member 35. Is maintained, and an integral descent is performed.

Next, the operator grips the grip portion 43 and presses the work button to switch the balance hoist 62 so that the third-stage operation, that is, the pulling operation of the cord 63 is balanced with the load on the holding device 20 side. As a result, the holding device 20 can be freely moved in a state where its own weight has disappeared.
Can be assembled by accurately applying window glasses C and D to. When the holding device 20 is freely moved, the guided body 40 is separated from the guide member 35,
Idle and withdraw in 35.

After the intended assembly is performed as described above, the suction by the vacuum pad 42 is released, and the work button is pressed to return to the first-stage operation, and the holding device 20 is moved to the rail member 32.
Integrate to the side. Next, the lifting drive device 50 is operated in the reverse direction to contract the pantograph type lifting guide device 22 upward, thereby returning to the initial state. Then self-propelled body 5
Is driven downstream at high speed.

Effects of the Invention According to the present invention having the above-described structure, the lifting guide device is moved up and the holding device is brought into contact with the lifting guide device by the air balance device, so that the pair of front and rear assembly parts held by the holding device can be automatically moved. It can be transported stably by the running body. By moving the lift guide device downward while the self-propelled body is running in synchronization with the body to be assembled, both the parts for assembly together with the holding device can be opposed to the assembly location of the body to be assembled. Next, by switching the contact force of the air balance device so as to balance the load on the holding device side, the operator can freely operate (move) the holding device in a state where its own weight has disappeared, and A pair of assembly parts can be applied to a location, either simultaneously or staggered. Therefore, the supply of the parts for assembly to the body to be assembled can be performed lightly and quickly even from above, and the assembling can be performed efficiently and easily and safely at two locations.
