DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a carousel having a horizontally long loading / unloading port 2 and is internally This is well known in the art, in which a large number of rotatable trays 3 are provided in a vertical circulation path having a front elevating path adjacent to the loading / unloading port 2 and a rear elevating path.
Reference numeral 4 is an operation panel, and 5 is a work table provided in front of the loading / unloading port 2.

As shown in FIGS. 2 and 3, the tray 3 is
Is a horizontally long one, and is provided with a plurality of load storage compartments 7 partitioned by partition plates 6 in the length direction thereof, that is, in the direction orthogonal to the rotation direction, and the front side adjacent to the load / unload port 2 is A front wall 9 of a cavity having a top plate 8 facing obliquely forward and upward is formed over the entire width of the tray, and the top plate 8 of the front wall 9 is provided with a light emitting display section 10 corresponding to each load storage compartment 7. A light emitting lens 10a to be formed is attached, and a light receiving window 12 as a light receiving portion corresponding to each light emitting display portion 10 is provided on a vertical front plate 11 of the front side wall 9. A condenser lens 12a is arranged inside each light receiving window 12, and the pair of condenser lenses 12a and the light emitting lens 10a are connected by an optical fiber cable 13 as a light transmitting means.

On the other hand, as shown in FIG. 2, the lower frame 14 of the loading / unloading port 2 is opposed to each light receiving window 12 of the tray 3 which has been stopped at the calling position P with respect to the loading / unloading port 2. A light emitting element such as a light emitting diode and a light source 15 such as a lamp are arranged in parallel. A work completion push button switch 16 is provided along the lower side of the loading / unloading port 2 corresponding to each loading storage compartment 7 of the tray 3 which is stopped at the calling position P with respect to the loading / unloading port 2. They are installed side by side. Reference numeral 17 is an elevating shutter that opens and closes the loading / unloading port 2.

At the time of loading and unloading work, the control device operates in accordance with a tray call command input on the operation panel 4 or given from a host computer, and the tray 3 is rotated in a vertical circulation path as is well known in the art. The tray 3 which is the target of the loading / unloading work is automatically called to the calling position P and stopped. Then, of the load storage compartments 7 of the tray 3 of the loading / unloading work target stopped at the calling position P, the light source 15 corresponding to one load storage compartment 7 of the loading / unloading work target is energized and lit.

The light of the light source 15 which is turned on passes through one of the light receiving windows 12 of the tray 3 stopped at the calling position P, which corresponds to the load storage compartment 7 which is the target of the loading / unloading work. It is condensed by the condensing lens 12a via the condensing lens 12a and is transmitted to the light emitting lens 10a of the light emitting display unit 10 connected by the optical fiber cable 13, and only the light emitting display unit 10 corresponding to the load storage section 7 which is the target of the loading / unloading work. It will emit light.

The worker carries out a predetermined loading / unloading operation with respect to the load storage compartment 7 corresponding to the light emitting display section 10. After the work is completed, the work completion push button switch 16 corresponding to the light emitting display unit 10 is operated to input the work completion to the control device. As a result, the power supply to the light source 15 that has been turned on is cut off, and the light source 15 is turned off, so that the light emitting display unit 10 on the tray 3 side that was emitting light is also turned off.

The control of turning on and off the light source 15 may be the same as the control of turning on and off the work position indicating lamp in the conventional carousel in which the work position indicating lamp is arranged in parallel outside the loading / unloading port 2. Therefore, detailed description will be omitted. Further, each of the light emitting display units 10 arranged side by side on the tray 3 side can be configured by a light emitting element such as a light emitting diode integrated with a light source, a lamp, or the like. In this case, the wiring for controlling energization for each light emitting display unit 10 on the rotating tray 3 side is required, but the contact on the tray 3 side and the power supply contact on the side of the tray circulation path make contact only at the calling position P. Then, all the light emitting display units 10 on the tray 3 side and the control device on the ground side can be connected. However, as in the above embodiment, each tray 3 is provided with a light receiving portion (light receiving window 12 and condenser lens 12a) separately connected to each light emitting display portion 10 via a light transmitting means (optical fiber cable 13). When arranging the light sources 15 side by side on the side of the tray circulation path, the light sources 15 facing the light receiving portions (the light receiving window 12 and the condenser lens 12a) of the tray 3 called by the loading / unloading port 2 are separately arranged. The wiring for controlling the energization for each light emitting display unit 10 on the rotating tray 3 side is unnecessary.

[0013]

As described above, according to the working position display device of the carousel of the present invention, the load storage compartment of the loading / unloading work is operated in the load storage compartment of the tray called to the loading / unloading port. In order to inform the person, the light emitting display section provided corresponding to each load storage section of the tray is arranged not on the outside of the loading / unloading port as in the conventional case but on the tray itself. It is possible to sufficiently bring the respective load storage sections of the tray corresponding to the above into close proximity. Therefore, even if the number of load storage compartments provided in one tray is very large, the worker can correctly identify the load storage compartment of the loading / unloading work object by the light emitting display unit that is turned on.
