The delivery mechanism 60 is used.

Then, in the third layout, the warehousing item A sent from the first loading section 21 is mounted on the one-side mounting position 40a of the transport table 37 and carried out to the second loading section 24. The delivery product B sent from the second carry-in section 22 is mounted on the other side mounting position 40b of the transport table 37 and carried out to the first carry-out section 23. The hierarchical relationship between the second carry-in section 22 and the first carry-in section 21 can be changed.

In this way, in each of the first to third layouts, it is possible to process the transport of the transported material 12 to be taken in and out in parallel, and the transported material 12 can be efficiently transported according to the arrangement of the upstream and downstream transport devices and the like. .. Then, when the transfer device 13 is applied to the automated warehouse system 10, a layout that can deal with differences in the arrangement of the storage unit 16 and the transfer unit 17 and the warehousing / delivery direction of the transported object 12 can be applied.

Here, the transport table 37 may be provided with two or more mounting positions 40. For example, when the transport table 37 is provided with two mounting positions 40a on one side and two mounting positions 40b on the other side, the other At the side mounting position 40b, there are two transported objects from the first delivery section 32 to the transport table 37 so that the transported object 12 first sent out from the upper second sending section 35 is mounted at the outer other side mounting position 40b. It is mounted, and two transported objects 12 are mounted in order from the second delivery section 33 located at the bottom to the one-side mounting position 40a on the back side at the one-side mounting position 40a (two are mounted at the same time from the second delivery section 33). It is also possible that these two transported objects 12 are carried out from the transport table 37 by the sending units 34 and 35.

Further, a plurality of objects 12 can be mounted on the transport table 37 at the mounting position 40a on one side, and a single number of objects 12 or vice versa can be mounted on the transport table 37 at the mounting position 40b on the other side. It is possible to mount the object 12. Then, in the first delivery section 32 and the second delivery section 33, the conveyed object 12 is mounted at a mounting position away from the other delivery section so that one delivery section has a mounting position used by the other delivery section. As a result, interference between the transported object 12 mounted earlier on the transport table 37 and the transport unit 12 mounted later is avoided, and the mounting position for the next transported object 12 to be mounted is left open.

As described above, according to the transport device 13 of the present embodiment, the warehousing product A sent from the first carry-in section 21 to the ascending transport section 26 by the transport device main body 20 is sent from the lower transport section 27 to the second carry-out section 24. By sending the goods B sent from the second carry-in unit 22 to the ascending transport unit 26 from the lower transport unit 27 to the first carry-out unit 23, the warehousing of the warehousing product A and the warehousing of the warehousing product B are performed in parallel. Can be done.

Further, since the transport table 37 is provided with a mounting position 40 for mounting the transported object 12 at at least two locations in the second direction Y, the warehousing product A and the warehousing product B, which are the transported objects 12, can be mounted and transported together. The object 12 can be transported more efficiently.

Further, since the delivery units 32, 33 and the transmission units 34, 35 are configured to move in the second direction Y with respect to the ascending transport unit 26 and the descending transport unit 27, the delivery units 32, 33 and the transmission unit 32, 33 and the transmission unit are transmitted in the first direction X. It is not necessary to provide a retracting space for the portions 34 and 35, and the distance between the ascending transport portion 26 and the descending transport portion 27 of the transport device main body 20 can be reduced to reduce the size. Moreover, it can also be used for the automated warehouse system 10 in which the distance between the two rows of storage units 16 is narrow.

Furthermore, since the moving directions of the delivery units 32, 33 and the delivery units 34, 35 and the transport directions of the transported object 12 by the delivery units 32, 33 and the delivery units 34, 35 are the same directions, the above the delivery units 32, 33 and It is possible to move the transported object 12 on the delivery units 34 and 35, and the transport efficiency of the transport device 13 can be improved.

That is, in the delivery units 32 and 33, the movement of the delivery unit 61 from the reception positions A1 and B1 to the delivery positions A2 and B2 and the movement of the transported object 12 on the delivery unit 61 are performed with respect to the inside of the ascending transport unit 26. Since it can be performed at the same time, the transported object 12 can be quickly arranged at a predetermined position of the ascending transport unit 26 as compared with the case where the delivery unit 61 is moved and the transported object 12 is moved separately. Therefore, even if the transport speed of the transported object 12 by the transport table 37 is increased, the delivery units 32 and 33 can handle it, and the transport efficiency of the transport device 13 can be improved.

Similarly, in the sending units 34 and 35, the sending unit 81 can be retracted and the transported object 12 received by the sending unit 81 can be retracted and moved simultaneously with respect to the descending conveying unit 27. Compared with the case where the sending unit 81 is retracted and moved after the object 12 is sent out, the timing of the retracting and moving of the sending unit 81 can be made earlier. Therefore, even if the transport speed of the transported object 12 by the transport table 37 is increased, the delivery units 34 and 35 can handle it, and the transport efficiency of the transport device 13 can be improved.

Further, the transport base 37 is provided with a plurality of fork portions 42 in the second direction Y in a comb-teeth shape, and the delivery portions 32 and 33 and the delivery portions 34 and 35 can be moved back and forth between the fork portions 42 of the transport base 37. Since a plurality of delivery carriers 63 and a plurality of delivery carriers 83 are provided, the moving directions of the delivery sections 32, 33 and the delivery sections 34, 35 and the deliverables by the delivery sections 32, 33 and the delivery sections 34, 35 are provided. The transport direction of 12 can be the same.

Further, the delivery mechanism 60 of the delivery portions 32 and 33 is arranged so as to face the carry-in portions 21 and 22 with the ascending transport portion 26 sandwiched between the receiving positions A1 and B1 and the delivery positions A2 in the ascending transport portion 26. Moves to B2, accepts the transported object 12 sent from the loading sections 21 and 22 to the ascending transport section 26 at the receiving positions A1 and B1, and loads the transported object 12 at the delivery positions A2 and B2 among the mounting positions 40 of the transport table 37. Since it is possible to deliver the transported object 12 to the mounting position 40 on the side away from the loading units 21 and 22, the transported object 12 from the loading units 21 and 22 to the transport table 37 with one delivery unit 32 and 33. Can be delivered, the configuration can be simplified, and the man-hours and control of the delivery operation can be simplified.

Further, since the delivery carrier 63 of the delivery mechanism 60 has a free roller 66 that conveys the transported object 12 sent from the delivery sections 21 and 22 in the receiving direction, a drive structure including a drive section is not required, and the configuration is simplified. At the same time, the man-hours and control of the transfer operation can be simplified.

Moreover, since the transport surface formed on the upper surface side of the plurality of free rollers 66 is provided with an inclination angle at which the transport material 12 fed from the carry-in portions 21 and 22 descends in the receiving direction, the transport material 12 can be moved. It can be reliably transported in the receiving direction.

The transport device is not limited to the application to the automated warehouse system, but can also be applied to other transport systems that carry in transports with different transport destinations from two directions from two directions and carry them out to the transport destinations in the two directions. It is possible to handle not only warehousing and warehousing items but also warehousing items of various attributes.

Although the embodiments of the present invention and modifications thereof have been described above, the embodiments and modifications thereof can be appropriately combined as long as the gist of the present invention is not deviated.
