2. The operations of the attachment angle adjusting motor 41 and the suction pads 50 ... Are controlled.

Next, the operation of the embodiment of the present invention having the above construction will be described.

The window glass W, which has been subjected to degreasing, primer coating, adhesive coating, etc., supplied from the previous step by the window glass transport line Lw, is adsorbed to the adsorption pad of the window glass transfer device 1. On the other hand, the carrier 4 of the window glass carrier 2 travels in the direction of the arrow a ′ in FIG. 1 and stops at the chain line position, where the window glass W moves from the suction pad of the window glass delivery device 1 to the window glass mounting device 5. It is delivered to the suction pads 50 ....

When a predetermined vehicle type (that is, a truck type vehicle and a wagon type vehicle) is transported by the vehicle body transport line Lb, an operator inputs vehicle type information to the vehicle type input device 55. Based on the vehicle type information, the control device 54 drives the turning motor 32 of the window glass mounting device 5 to rotate the vertical rotation shaft 31, thereby causing the windshield W adsorbed to the suction pads 50 to the vehicle body V. The windshield W is attached to the windshield W of the vehicle body V by rotating 90 ° to the mounting posture (posture orthogonal to the transport direction of the vehicle transport line Lb) and driving the lifting motor 27 to lower the rack bar 26. As shown in FIG. 7, the slide frame 4 supported by the left and right shafts 43 by driving the mounting angle adjusting motor 41 to match the height of the opening.
By rotating 4 the front and rear inclination angle of the windshield W is made to match the inclination angle of the windshield attachment opening of the vehicle body V.

When the operator confirms the position of the vehicle body V on the vehicle body transport line Lb and then operates the operating device 53 provided on the window glass mounting device 5, the carrier vehicle 4 moves from the chain line position in FIG. 1 to the solid line position. The vehicle travels in the direction of arrow a and stops on the vehicle body transport line Lb. During that time, the lock cylinder 42 restricts the longitudinal movement of the mounting plate 39, and the lock cylinder 45 restricts the lateral movement of the slide frame 44.
As a result, the delusion of the windshield W adsorbed on the adsorption pads 50 is prevented. Further, when the window glass attachment device 5 reaches the vehicle body transport line Lb, the elevating motor 27 exerts a predetermined torque based on the weight of the ascendable / descendable portion including the window glass W detected by the load cell 35, and the window glass is generated. W is suspended in a weightless state.

When the vehicle body V on the vehicle body transportation line Lb reaches below the window glass mounting device 5, the synchronous transportation motor 2
0 operates, and the window glass mounting device 5 travels along the carrier 4 in the direction of arrow b in FIG. 1 in synchronization with the vehicle body V. At this time, the windshield W adsorbed to the suction pads 50 is in a state of substantially facing the windshield mounting opening of the vehicle body V, and the lock by the lock cylinders 42 and 45 is released, so that the windshield W moves back and forth. And it is in a state of being able to move sideways.

Then, as shown in FIG. 3, an operator standing on the vehicle body transport line Lb grasps both ends of the left and right shafts 43 with both hands and moves them up and down in the direction of arrow cc ', whereby the windshield is moved. Finely adjust the vertical position of W. At this time, since the weight of the vertically movable portion including the windshield W is supported by the torque of the lifting motor 27, the operator can easily move the windshield W up and down with a slight force.

Further, holding the slide frame 44, the left and right shafts 43
By finely adjusting the left-right position of the window glass W by sliding along the direction of d-d ', and turning the boss member 48 around the front-rear axis 47 in the direction of e-e' by grasping the arms 49 ... After finely adjusting the rotational position of the windshield W by the user, the both ends of the left and right shafts 43 are grasped and the guide rails 38 are slid along the slide guides 37 to move the windshield W in the f direction to move the vehicle body V. Glue to the window glass mounting opening. At this time, wind glass W
Since the inclination angle of (1) is regulated in advance by the mounting adjustment motors 41 according to the vehicle type, the positioning operation of the windshield W can be performed extremely easily.

When the position of the window glass W is manually adjusted as described above, if the positional deviation from the window mounting opening of the vehicle body V is large, the operating device 53 is operated to turn the vehicle. Motor 32, lifting motor 2
7 and the mounting angle adjusting motor 41 can be driven to automatically adjust the position. Further, when some trouble is discovered before the windshield W is adhered, the synchronous conveying motor 20 may be driven at a higher speed than the normal synchronous speed by operating the operation device 53.
As a result, the windshield attachment device 5 can travel at a higher speed than the vehicle V, and the windshield W supported by the windshield attachment device 5 can be separated from the vehicle V.

When the operator operates the operating device 53 after the adhesion of the windshield W is completed, the suction by the suction pads 50 ... Is released, and the windshield mounting device 5 and the carrier 4 receive the next windshield W. Return to original position.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned embodiments, and various design changes can be made.

[0031]

As described above, according to the invention as set forth in claim 1, the suction pad which is supported on the elevating base so as to be capable of lateral movement, longitudinal movement, tilting about the lateral axis and rotation about the longitudinal axis. The window glass is adsorbed and held on the vehicle, and the elevating base is driven by the ascending / descending drive source so that the height of the window glass is aligned with the window opening for mounting the vehicle, and the window is attached in synchronism with the vehicle for bonding. Therefore, it is possible to easily finely adjust the position and angle of the window glass with respect to the window glass mounting opening, and perform accurate bonding.

According to the invention described in claim 2,
Since the inclination angle of the windshield can be automatically matched with the inclination angle of the windshield attachment opening of the vehicle by the attachment angle adjusting drive source, the work of adhering the windshield can be performed more easily and reliably.

According to the invention described in claim 3,
Since the lifting drive source holds the lifting base in a weightless state based on the output of the load cell, the fine adjustment of the vertical position of the window glass can be quickly performed manually with a small force.
