Supporting members 319 and 319 for supporting the instrument panel P are provided at the tip of 18. Further, the slider 317 is provided with a roller-shaped support member 320 that supports the instrument panel P in cooperation with the support members 319 and 319. A handle 322 is provided at the other end of the slider operation arm 321 having one end fixed to the slider 317, and an operator pushes and pulls the handle 322 to slide the slider 317 along the slide rail 315. You can At this time, the slidable range of the slider 317 is restricted by the stoppers 323 and 323 provided at both ends of the slide rail 315.

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

The instrument panel P carried in by the transport hanger Hp of the overhead conveyor Cp is previously placed on the cradle T of the instrument panel assembling station. The operator can use a pair of handles 108,
The work transfer device C is moved by grasping 108, and the support members 319, 319; 320 thereof are positioned below the instrument panel P mounted on the pedestal T. At this time,
The cylinder 309 is slightly extended from the state shown by the solid line in FIG. 5, the slider 303 is at the lower limit position in contact with the lower stopper 324, and the locking member 313 of the connecting arm 307 is covered by the slider 303. It is engaged with the locking member 314, and the support arms 318, 318 extend horizontally as shown in (a).

When an operator pushes an operation button (not shown) in this state to extend and drive the cylinder 309, the rotation of the connecting arm 307 is restricted by the engagement of the locking member 313 and the locked member 314. The slider 3 to which the driving force of the cylinder 309 is transmitted via the connecting arm 307.
03 rises along the slide rail 301. As the slider 303 rises, the support arms 318, 318 rise while keeping the horizontal state, and rise to the upper limit position shown in (b) to contact the upper stopper 324. Then, in the ascending process, the instrument panel P on the pedestal T is transferred onto the support members 319, 319; 320.

When the instrument panel P is transferred to the work transfer device C as described above, the work transfer device C is moved from the front of the pedestal T, and then the operation button is pushed to contract the cylinder 309. To drive. As a result, the slider 303 descends from the position (b) to the position (a) while keeping the supporting arms 318, 318 in a horizontal state, and abuts on the lower stopper 324 to stop. When the cylinder 309 is further contracted and driven, the lowering of the slider 303 is restricted by the lower stopper 324, so that the connecting arm 30
FIG. 7 shows the support shaft 306 guided by the guide cylinder 305 and FIG.
To the solid line position. When the support shaft 306 rotates, the support arms 318 and 318 supported by the support shaft 306 via the slider 317 rotate together with the instrument panel P to the position (c), and the instrument panel P is placed in the vehicle compartment. Tilt to match the mounting orientation.

Subsequently, the work transfer device C is coupled to the transfer hanger Hb of the overhead conveyor Cb for transferring the vehicle body B, and the instrument panel P is moved while moving the work transfer device C in synchronization with the transfer hanger Hb. Install it in the specified position in the passenger compartment. The joining is performed without stopping the overhead conveyor Cb.

That is, the pair of coupling members 207, 207 of the work transfer device C are moved to the obliquely upward posture by moving them onto the bent portions 209, 209 at the tips of the guide plates 208, 208 as shown by the chain line in FIG. In this state, by advancing the work transfer device C toward the moving transport hanger Hb, the coupling members 207, 207 are engaged with one beam 9 of the transport hanger Hb. When the work transfer device C is further advanced, the coupling members 207, 207 are retracted to the position shown by the solid line in FIG. 3 while being guided by the guide plates 208, 208. As the work transfer device C moves forward, the instrument panel P located at the position (d) in FIG. 3 is inserted from the door opening of the vehicle body B into the position (e) in the vehicle compartment.

The beam 9 engaged with the connecting members 207, 207 moves together with the transfer hanger Hb while sliding with respect to the connecting members 207, 207, and eventually the tip of the beam 9 is provided on the work transfer device C. The contact member 213 is engaged (see FIG. 2). As a result, the work transfer device C starts traveling in synchronization with the transport hanger Hb while being pulled by the transport hanger Hb.

As described above, the work of connecting the work transfer device C to the transfer hanger Hb is performed by simply moving the work transfer device C toward the transfer hanger Hb without delicate positioning. Since it is good, it can be performed extremely easily without requiring skill.

When the worker pushes the handle 322 to slide the slider 317 along the slide rail 315 of the support shaft 306 during the synchronous transfer of the transfer hanger Hb and the work transfer device C, the instrument panel P is It further advances from the position (e) in FIG. 3 to the position (f), and approaches a predetermined position in the vehicle compartment in a posture extremely close to the mounting posture.

Then, after another worker who gets into the passenger compartment receives the instrument panel P from the work transfer device C, an operation button (not shown) is pressed to press the cylinder 309.
By slightly driving the extension of the
8, 318 is returned to the horizontal posture. From this state, when a worker outside the passenger compartment moves the work transfer device C in a direction away from the transport hanger Hb, the coupling members 207, 207 slide in the opposite direction to the above and separate from the beam 9 of the transport hanger Hb. The synchronous transfer of the work transfer device C is completed.

Then, the worker in the vehicle compartment installs the instrument panel P received from the work transfer device C at a predetermined position in the vehicle compartment, and the work in the instrument panel assembling station is completed.

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

[0033]

As described above, according to the first feature of the present invention, one end of the connecting arm is fixed to the support shaft rotatably supported by the vertically movable slider, and the other end of the connecting arm is driven. The driving source drives the other end of the connecting arm in the up-down direction because the connecting arm and the slider are provided with a locking member and a locked member that can be driven in the up-down direction. Thus, the support shaft can be moved up and down together with the slider, and the support shaft can be rotated with respect to the slider.
As a result, the work on the support member provided on the support shaft can be raised and lowered and rotated to change the position and posture, and the receipt and delivery can be smoothly performed. Moreover, since the raising and lowering and the rotation are performed by the same drive source, the structure thereof can be simplified.

According to the second feature of the present invention, since the supporting member is slidably provided along the support shaft, the work can be moved in the horizontal direction, and the receiving and delivering of the work can be performed more smoothly. Can be done.
