A synchronous arm 13 as shown in FIGS.
0 is attached. Synchronous arm 130 is link mechanism 1
31, a cylinder 132, and an arm 133. The arm 133 is configured to rotate in the transport direction of the vehicle body B, so that the arm 133 does not interfere with the vehicle body B when the rod of the cylinder 132 is retracted. Furthermore, urethane 134 is fixed to the tip of the arm 133 to prevent damage to the front pillar B2 even if the arm 133 contacts the front pillar B2 of the vehicle body B in order to synchronize it with the vehicle body B. The hood W, which is held by the holding part 2 with the urethane 134 fixed to the tip of the arm 133 in contact with the front pillar B2, is positioned directly above the opening B1 of the vehicle body B.

The operation of the hood positioning and mounting device constructed as above will be explained. Placement member 1 of placement unit 1
1 is located at the upper position Y1 as shown in FIG. Then, the mounting member 11 descends to the lower position Y2, and the hood transfer device returns to its original position. At this time, the synchronization section 3 is
Alternatively, it is in the position shown in FIG. 6, with the locking piece 80a being clamped by the clamp member 83. The bracket 53 of the synchronizing section 3, that is, the holding section 2 is located at the upper position shown in FIG. In addition, in the synchronizing arm 130, the rod of the cylinder 132 is retracted, and the arm 133
is separated from the inside of the front pillar B2 of the vehicle body B.

Next, the rod of the cylinder 84 is moved back to unclamp the clamp member 83, and the electromagnetic clutch 68 is connected to operate the motor 66 to stroke the synchronizer 3 in the direction opposite to the direction of movement of the vehicle body B. It is moved to the end, the locking piece 80b is brought into contact with a stopper (not shown), and is clamped with a clamp member (not shown). In this state,
The holding part 2 mounted on the synchronizing part 3 is located above the hood W placed on the mounting member 11.

Next, the cylinder 56 of the synchronizing part 3 is operated to lower the holding part 2, and the cylinder 33 of the holding part 2 is further actuated to suck the hood W with the suction pad 32 and hold it with the locking piece 31. Then, the rods of cylinder 33 and cylinder 56 are retracted. Next, the cylinder 21 of the placing part 1 is operated to open the lower part of the placing member 11 using the link mechanism 22 as shown in FIG. The motor 20 is driven and raised to the upper position Y1. At the same time, cylinder 1 of synchronous arm 130
The rod 32 moves forward and rotates the arm 133, and after a while, the arm 133 is placed inside the front pillar B2 of the vehicle body B, which is placed on the slat conveyor C and transported.
The urethane 134 fixed to the tip comes into contact as shown in FIG. On the other hand, at the same time as the rod of the cylinder 132 moves forward, the locking piece 80b is released from the clamped state, and the electromagnetic clutch 68 is also brought into the unclutched state. It moves in synchronization with the vehicle body B by means of the rack 73, pinion 71, rail 77, and rollers 78, 79. Therefore, the hood W held by the holding part 2 attached to the synchronizing part 3 moves in synchronization with the vehicle body B.

Immediately after the synchronizer 3 moves together with the vehicle body B, the bracket 53, which has the holding portion 2 and the like attached to its tip, descends to the position shown in FIG. Then, release the suction pad 32 and locking piece 31 of the holding part 2, and insert the hood W into the opening B1 of the vehicle body B.
Position it completely and place it.

Next, while synchronizing with the vehicle body B, the synchronizer 3
The plate member 57 of is raised. Then, the locking piece 80a of the synchronizer 3 is moved synchronously with the vehicle body B until it comes into contact with the stopper 82, but just before stopping, the braking cylinder 88 is activated to press the pad 85 against the roller 78 to brake the synchronizer 3. At the same time, the shock of stopping is reduced by the damper 91. On the other hand, immediately before actuating the braking cylinder 88, the rod of the cylinder 132 of the synchronizing arm 130 is moved backward to move the arm 133 away from the front pillar B2 in the direction of movement of the vehicle body B.

When the locking piece 80a comes into contact with the stopper 82 and is clamped by the clamp member 83, the motor 95 is driven to move the bracket 53 upward. At this time,
The rod of the cylinder 21 of the mounting section 1 is moved back and the mounting member 1
1 is located in parallel with its lower part closed, and the next hood W is placed thereon at the lower position Y2 shown in FIG. The above is one cycle of the positioning and mounting operation of the hood W.

In this embodiment, the arm 133 of the synchronizing arm 130 is brought into contact with the inside of the front pillar B2 of the vehicle body B for synchronization, but it may be brought into contact with the inside of the rear pillar of the vehicle body B.
