In the figure, reference numeral 1 denotes a pair of box-shaped product storage sections with open bottoms, and 2 is a rotating shaft extending vertically in the center of the product storage section 1, with the lower end used to store the product. A connecting shaft 5 is rotatably supported by a shaft support 3 attached to the back plate 1a of the product storage section 1, and the upper end is rotatably inserted into a bearing 4 provided on the top plate 1b of the product storage section 1, by means of a pin 5a. connected.

Reference numeral 6 denotes a pair of flappers attached to the lower part of the product storage section 1 so as to be rotatable in the vertical direction via a shaft 6a. The bottom opening can be opened and closed.

Reference numeral 7 denotes a rotation control plate provided horizontally at the lower part of the rotation shaft 2 so as to be able to come into contact with the lower surface of the flapper 6. The rotation control plate 2 has a fan-shaped planar shape and controls its rotation. Depending on the position, downward rotation of the flapper 6 is allowed or prevented.

Reference numeral 10 denotes a pair of product locking plates (hereinafter simply referred to as locking plates), and the locking plates 10 are formed of tapered flat plates bent at an obtuse angle in the center in the vertical direction, and the lower and side edges of the lower end 10a. It has a wall surface 10b that protrudes in the opposite direction to the product pressure contact side. In addition, smooth curved surfaces are provided at the boundary portions between each of the wall surfaces 10b and the surface of the product locking plate 10 on the product pressure contact side, and at the boundary portions between the adjacent wall surfaces 10a. Furthermore, a substantially circularly curved shaft mounting portion 10c into which the shaft 11 is inserted is connected to the upper end of the locking plate 10.

Each of the locking plates 10 has the shaft mounting portion 10b pivoted on a horizontal shaft 11 that is fixed at one end to the back plate 1a of the product storage section 1 and at the other end to the front plate (not shown). The lower end portion 10a is located at a position where it can press against the product 30' directly above the lowest product 30 placed on the upper surface of the flapper 6.

Reference numeral 12 denotes a cantilevered horizontal arm provided between the locking plates 10 of the rotating shaft 2;
When the flapper 6 rotates downward from the horizontal position and the lowest product 30 falls from the bottom opening of the product storage section 1 and is carried out, the locking plate 10 on the same side
is pressed and rotated upward, so that the lower end 10a of the locking plate 10 can be projected into the product storage section 1 and brought into pressure contact with the product 30'.
