It can be carried out while maintaining the balance of the remaining amount.
Further, when products are stored in two rows in one product storage shelf, the components are shared (for example, product storage shelves, product outlets, Motor, etc.) and the space required for installation can be reduced.
[0016]
【The invention's effect】
The present invention is configured as described above, and has the following effects.
A product storage shelf having a product exit at the bottom and storing products in a plurality of rows in the vertical direction, and the products at the bottom of each row of product groups stored in the product storage shelves are alternately shifted in the horizontal direction. By having a carry-out mechanism for dropping from the carry-out port, the product group stored in each row is alternately lowered by one for each product while maintaining the balance of the remaining amount of goods between the rows. Can be carried out. In addition, in order to increase the storage capacity of products, compared to a conventional product storage shelf, for example, two units are arranged in common, the components can be simplified (for example, a product storage shelf, a product outlet, a driving device, etc.) and the installation can be simplified. The required space above can be reduced. Further, by alternately shifting two rows of products in the horizontal direction at the time of unloading, the products can be unloaded by merely providing one product unloading port.
[0017]
In addition, the unloading mechanism has a first extruded piece and a second extruded piece that are arranged to face the lowermost commodities of each product group, and the first extruded piece and the second extruded piece are in a horizontal posture and a vertical posture. It is possible to rotate between the posture and the other so that when one is in the horizontal posture, the other is in the vertical posture, and when turning from the vertical posture to the horizontal posture, the lowermost product is moved in the horizontal direction. When the extruded pieces that change alternately change from the vertical position to the horizontal position, the products are shifted horizontally and carried out, and the upper products are prevented from dropping in the horizontal position. Products can be easily carried out alternately. Thus, the unloading mechanism can be of a relatively simplified form.
[0018]
Further, the unloading mechanism comprises a columnar cam rotatably supported to face the lowermost product of each row of product groups , and each of the columnar cams is rotated by 180 ° to form two rows of product groups. By having a staggered semi-circular projection to shift the bottom product in the horizontal direction , the semi-circular projection shifts the product horizontally and pushes up the remaining product group so as not to descend. To hold. Therefore, two rows of commodities can be easily carried out alternately simply by providing one cam.
