[The problem that the idea attempts to solve]

However, in this device, as the vertical dimension of the side plate increases, when the product is pressed against the side plate by the flapper 7 or 7', the side plate may spread outward, which may cause trouble in carrying out. This problem can be solved by increasing the strength (thickness, etc.) of the side plates themselves, but this method causes new problems such as increased cost and increased weight.

In view of this, the present invention aims to provide a product storage device that can prevent the side panels from expanding outward as the products are carried out with a simple structure without increasing the strength of the side panels of the product storage section. .

[Means for solving problems]

In the present invention, at least one pair of flat flaps are arranged side by side in a product storage area formed by a back plate, left and right side plates, and a top plate so as to be rotatable around their opposite sides, and the product storage area is A rotary shaft driven by a motor is pivotally supported in the center so as to extend in the vertical direction, and the rotary shaft is provided with a rotation control plate that rotates together with the rotary shaft to alternately rotate each of the flappers; An automatic machine comprising a member that engages with the product immediately above the product loaded on the flapper and clamps the product between the side plate and prevents the product from falling when the product is being carried out. This is applied to a product storage device of a vending machine, and product fall prevention plates that prevent products stacked on the flapper from falling are rotatable in the front-back direction on both sides of the front opening of the product storage section. , each of the left and right side plates is provided with a spread prevention plate for preventing the side plates from spreading at a position corresponding to the arm, and the spread prevention plate has an L-shaped part, and a part of the L-shaped part is provided. is fitted into a hole provided in the fall prevention plate without interfering with its rotation and can be engaged with the edge of the hole in the closed state of the fall prevention plate, thereby preventing lateral displacement of the fall prevention plate. It is characterized in that it is configured to be blocked by.

[Effect]

In the configuration of the present invention, the product fall prevention plate is in a closed state except when filling the product storage section with products. At this time,
A part of the L-shaped part of the spread prevention plate fits into the hole of the product fall prevention plate and engages with the edge of the hole.
The product drop prevention plate can only be rotated in the front-back direction and not displaced laterally, and is thus in a state where it can prevent the spread prevention plate from moving laterally. That is,
When carrying out the goods on the flapper, the goods directly above the goods to be carried out are pressed against the side plates by the arms, and as a result, the side plates tend to spread laterally. However, a spread prevention plate is attached to the side plate near the part that receives this pressing force, and even when the side plate is pressed, the spread prevention plate is prevented from moving laterally by the product fall prevention plate, so it is indirectly Spreading of the side plates is also prevented. The hole in the product fall prevention plate is of such a size that it will not be blocked by the L-shaped portion of the expansion prevention plate when it rotates in the front-rear direction.

〔Example〕

Examples of the present invention will be described below.

FIG. 1 is a front view of an embodiment of the product storage device according to the present invention. In FIG. 1, product fall prevention plates 30 and 30' are provided on both sides of the open front portion of the product storage section 1, respectively. These product fall prevention plates 30, 30' are
To prevent the products stacked on 3' from falling out of the product storage section 1 due to vibration or the like. FIG. 2 is a partial cross-sectional view taken along line - in FIG. 1. In order to prevent the product from getting in the way when transporting the product, the product fall prevention plate 30 is mounted on the top and bottom with shafts 31, as shown in FIG.
It is rotatably supported in the direction of the arrow, that is, in the front-back direction. The product fall prevention plate 30 is provided with a shaft 31 between the top plate 11 of the product storage section 1 and the lower component, and since the shaft 31 does not bend, the product fall prevention plate 30 is also displaced laterally. There's nothing to do.

Further, spread prevention plates 32, 32' having a substantially U-shaped cross section are attached to the front ends of the left side plate 12 and right side plate 13, respectively, at positions corresponding to the flappers 7, 7'. Particularly, a part of the spread prevention plates 32, 32' is provided so as to fit into square holes 301, 301' provided in the product fall prevention plates 30, 30' in an open state. That is, the spread prevention plate 3
The cross-sectional shapes of 2 and 32' and the sizes of the square holes 301 and 301' are made so as not to impede the rotation of the product fall prevention plates 30 and 30'.

In this way, during product sales, the product drop prevention plates 30, 30' are in a closed state, and the square holes 301, 3
L-shaped portion 32 of the blocking plate 32, 32' spreads within 01'
A part of 1 is inset. As a result, when the product is pressed against the side plate 12 or 13 and the side plate 12 or 13 tries to spread outward, the spread prevention plate 32 or 32' also tries to displace outward. It is blocked at the edge of '. That is, as mentioned above, since the product fall prevention plates 30, 30' are prevented from being displaced laterally by the shafts 31, 31', the spread prevention plate 3
2, 32' are also prevented from outward displacement. Therefore, outward expansion of the side plates 12 or 13 is also prevented. That is, in the present invention, by utilizing the mechanical strength of the product fall prevention plate provided to prevent the product from falling, it is possible to prevent the side plate from deforming as the product is being carried out.

[Effect of idea]

As explained above, according to the present invention, a spread prevention plate is provided on the side plate of the product storage section, and
By engaging a part of this spread prevention plate so as not to impede the rotation of the product fall prevention plate, the mechanical strength of the product fall prevention plate is utilized to prevent the spread prevention plate from moving laterally, As a result, lateral displacement of the side plate can also be prevented. Therefore, with a simple structure in which a spread prevention plate is provided on the side plate and a hooking hole is provided in the product drop prevention plate, it is possible to prevent troubles in carrying out the product due to deformation of the side plate as the product is carried out. Therefore, there is no need to strengthen the strength (plate thickness, etc.) of the product storage section, especially the side panels, and cost increases can be suppressed.
