[0016]
As shown in FIG. 2, a plurality of instrument panels B are supplied to the supply station 2 by a carriage 16 on which a plurality of setting jigs 15 for the instrument panel B are mounted.
As shown in FIG. 8, each set jig 15 includes a pair of left and right rod-shaped jig bodies 15a and 15a erected on the carriage 16, and a frame of the instrument panel B attached to the upper end of each jig body 15a. A clamp cylinder 15c connected to a pin 15b fitted to an end of a horizontally long main frame pipe B1c (FIG. 9) of the member B1 and an end side edge of the frame member B1 attached to each jig body 15a And an engagement pin 15d for preventing the instrument panel B from rotating.
Each jig is attached to the guide block 15e for assembling jig 3 to the upper end of the body 15a, a positioning hole 15f formed in the guide block 15e, whereas, at each end of the assembly jig 3, FIG. As shown in FIG. 6, a positioning pin 17 that can be fitted into the positioning hole 15f is suspended, and a proximity switch or optical type that detects the lowering of the assembly jig 3 to a predetermined receiving position with reference to the guide block 15e. A sensor 18 composed of a distance measuring device or the like is attached.
The carriage 16 is positioned at a fixed position of the supply station 2 by a stopper 2a provided at the supply station 2 and left and right guides 2b and 2b.
[0017]
When receiving the instrument panel B, the assembly jig 3 is moved down to a position above the set jig 15 that supports the instrument panel B to be received this time on the carriage 16 positioned at the supply station 2, When the assembly jig 3 is lowered to a position where the positioning pin 17 starts to enter the positioning hole 15f, the lock by the lock cylinders 12, 13, and 14 is released, and the assembly jig 3 is lowered in a floating state. According to this, the positioning pin 17 is fitted to the positioning hole 15 f following the positioning hole 15 f, and the assembly jig 3 is positioned in the horizontal direction with respect to the setting jig 15. Then, when the sensor 18 detects the lowering to the predetermined receiving position, the lowering of the assembling jig 3 is stopped, and the assembling jig 3 is positioned in the vertical direction with respect to the setting jig 15, The clamp pin 9 and the phasing pin 10 are closed. In this case, the positioning of the assembling jig 3 with respect to the setting jig 15 causes the clamp pin 9 and the phase of the assembling jig 3 to be positioned in the holding hole B1a and the phasing hole B1b of the instrument panel B on the setting jig 15. Since the pin 10 is aligned with the center, the pins 9 and 10 are securely fitted in the holes B1a and B1b. Next, the pin 15b is detached from the main frame pipe B1c by the clamp cylinder 15c, and then the assembly jig 3 is raised to lift the instrument panel B from the set jig 15 and complete the reception.
[0018]
When the positioning accuracy of the assembling jig 3 with respect to the setting jig 15 is poor, the instrument panel B is centered with respect to the assembling jig 3 by fitting the clamp pin 9 into the gripping hole B1a. Although it is necessary to fit the phasing pin 10 into the phasing hole B1b, in this embodiment, the assembly jig 3 can be positioned with high accuracy with respect to the setting jig 15, and therefore the clamp pin 9 and the phasing pin 10 can be simultaneously fitted into the gripping hole B1b and the phasing hole B1b. Therefore, the clamp pin 9 and the phase determination pin 10 can be opened and closed by a common drive source.
[0019]
Further, it is possible to form a flange portion that contacts the upper surface of the guide block 15e when the positioning pin 17 is lowered to a predetermined receiving position, and the sensor 18 can be omitted. However, in this case, there is a problem that an impact acts on the jig main body 15a and the movable mechanism 4 by the contact of the flange portion with the guide block 15e, and the lowering to a predetermined receiving position is caused by the sensor 18 as in the above embodiment. It is desirable to detect and stop the descent of the assembly jig 3.
[0020]
