With the second support portion positioned at the delivery position, the article supported by the second support portion is transported by the second transport portion, so that the third support portion positioned on the front side of the second support portion Can be supported.
In this way, the article stored in the storage unit can be taken out by the first transport device, and the taken-out article can be transported by the second transport device so as to be supported by the third support unit. Automation can be achieved.

The control device then supports all of the articles stored in the storage shelf among the articles specified by one order information (hereinafter, abbreviated as all ordered articles) in a plurality of third supports. The operation of the first transport device and the second transport device is controlled so that one or more of the sections are simultaneously supported (hereinafter abbreviated as simultaneous support).
By the way, all the ordered articles may be transported together at one time by the second transport device so that all the ordered articles are simultaneously supported by the third support part. All articles may be conveyed by the second conveying device in a plurality of times.

As described above, since all the ordered articles are simultaneously supported by the third support portion, it is easy to collect the ordered articles. That is, when all the ordered articles are conveyed in a plurality of times, compared to the case where the articles are collected and collected every time the articles are conveyed to the third support section. By collecting the articles in which all the ordered articles are simultaneously supported by the third support part, it is easy to collect all the ordered articles. Also in this point, picking can be performed efficiently.
Accordingly, it has become possible to provide a picking facility that can automate the picking work and efficiently perform the picking work.

  Here, in the case where there are a plurality of articles to be taken out stored in the storage shelf among the articles specified by one order information, the control device selects the plurality of articles to be taken out. After being supported by the second support part from the storage shelf, a plurality of articles to be taken out supported by the second support part are supported by one or more of the plurality of third support parts. For this purpose, it is preferable to control the operations of the first transfer device and the second transfer device.

  According to this configuration, even when there are a plurality of articles to be taken out, the plurality of articles can be collectively transported at a time by the second transport device. Therefore, when there are a plurality of articles to be taken out, the plurality of articles can be efficiently transported to the third support unit as compared with the case where the plurality of articles are transported in a plurality of times by the second transport device. Can do.

  In addition, the first transport unit includes a plurality of projecting portions projecting above a support height for supporting an article in the second support unit with a space in the shelf front-rear direction, and the plurality of projecting portions. A first drive unit that moves the articles in the row state in the forward direction, the storage shelf includes a plurality of the storage units in a state of being aligned in the width direction of the shelf, and the storage unit includes the width of the shelf It is preferable that a space for replenishing an article for an operator to replenish an article is formed in the accommodation section between the other accommodation sections adjacent in the direction.

According to this configuration, a plurality of articles can be stored in a row in the storage unit in a state where the articles are positioned between a pair of protrusions adjacent to each other in the longitudinal direction of the shelf. In this manner, with the plurality of articles stored in a row, the plurality of protrusions are moved forward by the first drive unit, whereby the articles can be taken out one by one from the storage unit. And since there is a protrusion between the articles in the row state, it can be transported forward while maintaining a constant interval between the articles in the row state. Easy to remove from the storage.
As described above, when an article is stored in a state of being located between the protrusions, it is difficult for the protrusions to be replenished from the rear side of the storage part due to the protrusion. However, since an article replenishing space is formed between the storage units adjacent in the width direction of the shelf, the operator can easily replenish from the lateral side to the storage unit from the article replenishing space. can do.

  The plurality of protrusions may be configured at an upper portion of a spiral formed in a spiral shape with a rotation axis along the shelf front-rear direction as a center, and the first drive unit may be configured to rotate the spiral around the rotation axis. It is preferable to rotate the

  According to this structure, since the 1st conveyance part is the structure which rotates a helical body around a rotating shaft center, for example compared with the case where a 1st conveyance part is comprised with the belt conveyor provided with the protrusion part. Thus, the configuration can be simplified.

  In addition, the transport device includes a third transport device and a fourth transport device, and the third transport device includes a third transport unit corresponding to each of the plurality of third support portions, and the third transport device. The transport unit is configured to transport an article supported by the corresponding third support unit along a first transport direction, and the fourth transport device includes a fourth support unit that supports the article. A plurality of fourth support units arranged in a second transport direction intersecting with one transport direction and moving the plurality of fourth support portions along the second transport direction; Of the articles specified by the one order information, the articles supported by the third support section are assigned to the fourth support section assigned to the one order information specifying the article. It is preferable to control the operation of the third transport device to support it. It is.

According to this structure, the 4th support part of a 4th conveying apparatus is allocated with respect to one order information, The 4th support part moves to a shelf width direction by a 4th drive part. Then, the article supported by the third support unit is transported to the transport downstream side in the second transport direction by the third transport unit, so that the article supported by the third support unit is transported downstream from the transport unit. Can be supported by the assigned fourth support located in
In the case where a plurality of storage shelves are provided, the first transfer is performed in each of the plurality of storage shelves even when the articles specified by one order information are distributed and stored in the plurality of storage shelves.

Therefore, for example, when a container is placed on the belt of the belt conveyor and this container is used as the fourth support portion, it is necessary to lower the container from the belt conveyor as the article is taken out from the container. However, since the fourth support portion is configured by the belt portion of the belt conveyor, it is only necessary to drop the article from the belt portion, so that it is possible to improve the picking work efficiency.

  In addition, a second storage shelf that includes a plurality of storage units arranged in the width direction of the shelf and stores articles according to type in the plurality of storage units is provided, and the front side of the second storage shelf A plurality of fifth support portions arranged in the shelf width direction, wherein the plurality of fifth support portions includes the same number of fifth support portions as the plurality of storage portions of the second storage shelf, Among the articles specified by one order information, the second storage shelf is arranged in a state of being present on the front side of each of the plurality of storage units of the second storage shelf. It is preferable to control the operation of the first transport device so that the article stored in the container is supported by the fifth support portion.

  According to this structure, the 5th support part is supported with respect to each of the storage part in a 2nd storage shelf. Therefore, when an article is taken out from the storage section of the second storage shelf by the first transport device, the taken-out article can be supported by the fifth support section by being received by the fifth support section. Therefore, the articles stored in the storage unit of the second storage shelf can be transported so as to be quickly supported by the fifth support unit.

  Further, the storage shelf is configured by arranging a plurality of storage unit rows in which the storage units are arranged in the vertical direction in the shelf width direction, and the second support unit includes a plurality of storage unit rows corresponding to each of the plurality of storage unit rows. The second drive unit is configured to independently move the plurality of second support parts in the vertical direction, and the third support part. It is preferable that a plurality of are provided in a state of being separately provided on the front side of the second support portion, corresponding to each of the plurality of second support portions.

According to this configuration, the second support portion is provided separately for each of the plurality of storage portion rows. The second transport device can move the second support unit to the receiving position corresponding to each of the plurality of storage units simply by moving the storage unit in the vertical direction as the arrangement direction of the storage units. Therefore, compared with the case where the 1st support part is moved to the up-and-down direction and the shelf width direction, simplification of the composition of the 2nd conveyance device can be attained.
In addition, since a plurality of articles taken out from the plurality of storage unit rows can be simultaneously conveyed using the plurality of second support parts, the articles taken out from the storage part are efficiently supported by the third support part. Can be transported.
