It is always urged backward, that is, to the right in FIG. The pad 45b comes into contact with the guide member 23 of the support arm 20 when the support arm 20 is flipped up from the holding position P1 to the retreat position P2.

Next, the operation of the thus configured handling mechanism will be described. Many window glasses G
Moves the pallet 10 stored in the upright position to perform positioning for taking out the window glass G one by one. The positioning of the pallet 10 is performed by arranging the pallet 10 such that the positioning member 14 below the pallet 10 is located at a predetermined position. At this time, each support arm 20 is arranged at a holding position P1 for holding the window glass G.

The take-out device 30 is positioned at a take-out position facing the front of the frontmost window glass G in the pallet 10. As a result, each suction cup 32b is pressed against the surface Ga of the window glass G, and in this state, the air in the suction cup 32b is evacuated so that the suction cup 32b is adsorbed on the surface of the window glass G. At this time, the pad 45b of the work holding portion 45 of the shaking arm 42 is pressed against the surface Ga of the window glass G by the compression spring 45d.

The plunger 41b of the cylinder 41 provided in each arm retracting mechanism 40 is shortened, and each shaking arm 42 is swung upward (in the direction of the arrow in FIG. 4).

The support arm 20 is stably disposed at the retracted position P2 by its own weight without passing through the position directly above the swing shaft 21a of the support arm 20.

In other words, when the support arm 20 is flipped up, the trajectory R of the pad 45b is
With reference to the zero pivot shaft 21a, the pivot shaft 21a can be accommodated on one side of the pivot shaft 21a, that is, only on the left side in FIG. 3, without exceeding the pivot shaft 21a. The left support arm 20 is also jumped up from the holding position P1 to the retracted position P2 in the same manner as the right support arm 20.

After the left and right support arms 20 have been retracted from the extraction path K in this way, the extraction device 30
Is moved forward, that is, to the left in FIG.
The window glass G can be taken out of the pallet 10. After transferring the taken out window glass 10 to a predetermined position, the above operations are repeated, so that the window glass G can be taken out one by one from the pallet 10 one by one.

According to the present embodiment, the handling mechanism can be configured by additionally mounting the arm retreat mechanism 40 to the conventional take-out device 30.
The structure can be simplified as compared with the case where the arm retracting mechanism 40 is provided separately from the take-out device 30, and furthermore,
The support arm 20 can be automatically jumped from the holding position P1 to the evacuation position P2 by a simple handling mechanism based on a combination of the support arm 20 and the arm retraction mechanism 40, so that the handling mechanism can be easily automated. it can.

Further, by providing the work holding portion 45,
Window glasses G having different curvatures on the surface can be mixedly loaded in the same pallet 10 and at the retreat position P2.
There is an effect that the handling mechanism can be more easily automated without the support arm 20 which has been flipped up to obstruct the next window glass G being taken out.
