At one end of the fixed path 9 is formed a separating area 57 for transferring the magazine 55. In the separating area 57, the magazine 57 is transferred by a transfer device such as a conveyor.

Next, the warehousing operation in the above embodiment will be described.

In a state where the delivery device 10 is opposed to the sorting place 57 and is stopped, the magazine 55 in this sorting place 57 is delivered onto the mounting table 20 by the transfer device. In this magazine 55, many articles 56
It is stored with a part of the turntable 17 side exposed.
In this state, the traveling machine body 13 is caused to travel, the elevating table 15 is moved up and down, and the turntable 17 is opposed to the intended compartment storage space 2. At this time, the rotary table 17 stops rotating with the direction of the recess 25 facing the mounting table 20 side. Further, in the loading / unloading device 19, the fork 64 is in the lowered position, and the pressing plate 67 is
Is in the raised position by the lifting device 77, and the holding plates 80A, 80B
Are spaced apart from each other. In this state, first, the motor rotates the screw shaft 29 to move the nut body 31 and is guided by the guide rail 27 to advance the box frame body 60 via the connecting plate 34. This causes the fork 64 and the pressing plate 67 to project into the magazine 55 below and above the article 56. Further, both sandwiching plates 80A and 80B are located outside the front side surface where the article 56 is exposed from the magazine 55. Next, the fork lift motor 70 is driven, and the crank mechanism 71
The fork 64 is lifted via the to lift the article 56, and the presser plate lifting motor 75 is driven to drive the cam mechanism 76.

As a result, the article 56 is drawn onto the turntable 17 as shown in FIG. Then turn table 17 around vertical axis 16
The article 56 is rotated 90 degrees to face the intended compartment storage space 2.

From this state, the stop position confirmation device 43 is operated. That is, the cylinder device 50 is contracted, and the pushing / pulling rod 45 is caused to project through the piston rod 51, the holder 52, the sliding cylinder 48, the spring 49, and the stopper 46. The tip end engaging pin 42 of the pushing / pulling rod 45 that has moved in projection engages with the engaged hole 41 as shown by the phantom line in FIG. 1, so that the abnormality detecting device 53 does not operate. After the cylinder device 50 reaches the contraction limit, it immediately shifts to the extension motion, and the push-pull rod 45 is stored in the rotary table 17. As described above, when the abnormality detecting device 53 does not operate, the take-in / take-out device 19 performs the warehousing operation.
That is, the box frame 60 is moved forward by the above-mentioned operation, and the article 56 is thrust into the intended compartment storage space 2 via the fork 64, the pressing plate 67, and the sandwiching plates 80A and 80B. Next, the fork elevating device 72 lowers the fork 64, the pressing plate raising device 77 raises the pressing plate 67, and the driving device 81 moves the holding plates 80A and 80B away from each other to support and open the article 56. While passing it between the pair of left and right receiving plates 6. After that, the loading / unloading device 19 is moved backward. At the time of operation of the stop position confirmation device 43 described above, when the lift table 15 is stopped slightly above and below the predetermined position, the engaging pin 42 that protrudes does not engage the engaged hole 41,
It contacts the front surface of the partition plate 4 and is prevented from protruding further. At this time, the stopper body 46 stops facing the abnormality detecting device 53, and the abnormality is detected. The remaining contracting movement of the cylinder device 50 after the protrusion is blocked is absorbed by the sliding cylinder 48 moving against the spring 49. After the abnormality is detected and the engaging pin 42 is moved back and forth, the loading / unloading device 19 is not operated, and the lift 15 is moved up and down again to adjust the vertical position. After the stop, the stop position confirmation device 43 is operated again, and the engagement pin 42 is projected to confirm the stop position. Such repetitive confirmation action is performed many times until the abnormality detection device 53 does not operate.

As described above, after the goods 56 have been stored, the next storage is carried out.
It is rotated 90 degrees around 16 and puts in / out device 19 in magazine 55
Then, the article 56 is taken out from the magazine 55 by the above-mentioned operation. In addition, the transfer device 10 may be configured to move the elevating table 15 only vertically, or to move the traveling vehicle body 13 and elevating the table 15.
By moving up and down, the rotary table 17 is made to correspond to the compartment storage space 2 for the next purpose. After that, the desired warehousing work is performed by the same action as described above.

When the magazine 55 is empty, the delivery device 10 is returned to the sorting area 57, the empty magazine 55 is lowered, and a new real magazine 55 is loaded.

By performing the opposite operation to the above, the target article 56 is taken out from the partitioned storage space 2 and the empty magazine 55 is removed.
You can enter inside and leave the store.
