SUMMARY OF THE INVENTION However, the flow
In the rack-type picking system, it is necessary to replenish the products on the pallets taken out of the automatic warehouse at a time by dividing them into individual packaging units, and the size of the flow racks has been increased. Also, to prevent the flow rack from becoming too large,
If the designated quantity is divided into individual packaging units and replenished in the flow rack, the remaining goods must be re-stocked, which doubles the load on the automatic warehouse.

Further, in the flow rack, a gravitational conveyance method is used for conveying the goods, and the conveying force of the goods in the flow rack often depends on the weight of the goods. It may not be transported by being caught inside. In particular, in a freezer warehouse, since the rollers do not rotate due to icing of the free rack to the free roller bearings and the goods are no longer conveyed, gravity transport type flow rack picking in the freezer warehouse. It is difficult to use the system.

Further, in the flow rack, since the goods are slid on the rack by the weight of the goods, a collision between the goods occurs, and the goods may be damaged. Therefore, it has been difficult to apply to fragile products such as beer bottles.

In the automatic picking system disclosed in JP-A-2-52807 and the stratified picking system disclosed in JP-A-5-155405, there is little possibility that the product will collide and be damaged. The product pallets must be taken out of the shelves of the automatic warehouse together with the pallets in accordance with the picking timing, the required quantity must be taken out, and the rest must be restocked. Therefore, when both the number of types and the number of sorting destinations are large, the load on the automatic warehouse is doubled, and the processing time is slowed. For this reason, there is a limitation that it can be used only when either the number of varieties or the number of sorting destinations can be reduced.

The present invention has been made in order to solve such disadvantages. Even when both the number of varieties handled and the number of sorting destinations are large, the processing speed is reduced and the processing speed is reduced. It is an object of the present invention to obtain a picking device that can be surely sorted.
