DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a product storage column having a front opening and a product storage opening 2 provided therein. Numeral 3 is a rotary unloading member for unloading the product, which is rotatably disposed in the product storage column 1 in the vertical direction, and is a so-called spiral in which gaps for inserting and supporting the products described later are formed at regular intervals. ing. The rotary carrying member 3 is attached and fixed to a vertical rotating shaft 4 disposed at the center thereof via an upper supporting rod 5a and a lower supporting rod 5b. Here, the lower supporting lot 5b usually supports the lowest product and waits for sale.
When the rotating carry-out member 3 rotates according to the sales command, it also loses its support and serves as a member for sending out the product. The lower end of the rotating shaft 4 is rotatably supported by the tip of a support 6 provided below the product storage column 1.

As shown in FIGS. 1 and 3, between the pitches of the rotary carrying member 3 described above, for example, products 10a, 10b, 10c, 10a, 10b, 10c, cup-shaped products such as cup-shaped ice and cup ramen. Four 10d are evenly arranged and filled.

Here, of the products placed on the rotary carrying-out member 3, the right products 10a and 10b are both entered in a state inclined toward the front side, and conversely, the two left products 10c and 10c.
10d both enter in a state inclined to the back.

Thus, the four products 10a, 10b, 1
In the rotating carry-out member 3 in which 0c and 10d are evenly arranged around the circumference, one commodity is sent out and dropped one by one quarter (90 degrees) of rotation.

A drive unit for driving the rotary shaft 4 is provided on the upper part of the product storage column 1 and has a drive motor 13 with a reduction gear 12, a joy shaft 14 transmitted and rotated via the reduction gear 12, and the like. Consisting of And joint shaft 1
The rotating shaft 4 and the joint shaft 14 are connected to each other by a connecting pin 15 provided at the lower end of 4, and the rotational force of the drive motor 13 is transmitted to the rotary carrying member 3.

Reference numeral 16 denotes a motor mounting plate,
Thus, the drive motor 13 with the reduction gear 11 is mounted and fixed. A magnet mounting plate 18 is attached to the joint shaft 14.
a and 18b are attached by screws 19 and 19, and four magnet mounting plates 18a and 18b each having a rectangular shape as shown in FIG.
The magnets 21a, 21b, 21c, 21d are attached to the corners so as to be evenly scattered in four directions.

On the other hand, the magnets 21a, 21b, 21c,
A reed switch 22 operated by 21d is provided in a position adjacent to the mounting plates 18a and 18b and supported by the motor mounting plate 16 at one place therearound.

Accordingly, the rotation of the rotary carrying member 3 causes the magnet 2 to rotate.
When 1a to 21d rotate and approach the reed switch 22, the contacts in the reed switch 22 are operated. Specifically, when the customer presses the selection switch and the drive motor 13 is energized, the rotary carrying member 3 rotates, and one product on the rotary carrying member 3 drops. Then, before the second product falls, the magnet operates the reed switch 22 to cut off the power supply to the drive motor 13 and terminate one sales cycle.

That is, the four magnets 21a to 21d that rotate with the reed switch 22 constitute motor rotation control means for controlling the rotation stop of the drive motor 13 to intermittently rotate the rotating shaft 4 by 90 degrees.

Reference numeral 24 denotes a front door for opening and closing the product storage opening 2 of the product storage column 1, and has curled portions 25, 2 on one side.
The support portions 26, 26 provided on the upper and lower sides of the product storage column 1 as shown in FIG.
The front door 24 is inserted into the curled portion 2
It is rotatably supported around 5, 25 as a fulcrum, and opens and closes the product storage opening 2.

As shown in FIG. 1, a stopper 28, which is one member of the front door closing device, is attached to the front door 24 above the rear portion opposite to the pivot side.
On the other hand, a leaf spring 29, which is the other member for locking the stopper 28, is attached and fixed to the product storage column 1 with screws 30.

Therefore, when the front door 24 is opened, the handle portion 24c is pulled forward and the stopper 28 is moved to the leaf spring 29.
It can be opened out of the way. When closing, you can do it in the reverse way.

Next, the products 10a to 1a are stored in the product storage column 1.
A configuration for arranging four 0d's evenly as shown in FIG. 3 and storing and holding them at those positions will be described.

The inner products of the back wall 1H of the product storage column 1 extend vertically and protrude inward, and all the two products 10b and 10c at the back of the product on the rotary carrying member 3 move together. A fourth holding member 31 that is separately held so as not to be attached is attached.

On the other hand, all the two front products 10 that extend vertically and protrude from the rear surface of the front door 24 so as to face the fourth holding member 31 and ride on the rotary carrying member 3.
A fifth holding member 32 for holding the a and d separately so that they do not move with each other is attached. The fourth and fifth
The holding members 31 and 32 are formed of a metal plate or the like having such a rigidity that the products 10a to 10d are not damaged.

A third holding member 33 is provided on the right side wall 1R of the product storage column 1 at a position on the near side thereof, that is, at the edge of the open side of the product storage opening 2. The third holding member 33 is sandwiched by the mounting plate 51 and is attached to the support piece 55 with screws 52.

The third holding member 33 is made of a flexible material such as resin, and when the front door 24 is opened to fill the product, as shown in FIG. (Indicated by dotted lines) to allow the product to be filled by bending in the pushing direction, and when the product enters (product 10 shown by a dotted line), the product elastically returns to its original state and locks the product so as not to move to the front. It has become.

That is, in relation to the inclination of the rotary carrying member 3,
The product 10a entering the right front position is about to fall to the front. Fifth holding member 32 of front door 24 closed at the time of sale
The product 10a is supported, but cannot be held when the front door 24 is filled. In this case, as shown in FIG. 5, the third holding member 33 hits the product 10a and prevents the product 10a once filled from falling along the inclination of the rotary carrying member 3.

Further, a first holding member 35 made of the same flexible material and extending in the vertical direction and projecting inward is attached to the center of the inner surface of the right side wall 1R of the product storage column 1. The first holding member 35 has a recess 5 formed in the right side wall 1R.
8a which is positioned at 8a and is held by the mounting plate 56.
It is fixed at 7. The first holding member 35 is also bent to the back by an external force.

Therefore, as shown in FIG.
The product 1 which is bent to the right of the product storage column 1 by bending 3
0 is pushed further inward, the first holding member 35
And can be filled into the right side of the product storage column 1 as the product 10b indicated by the dotted line.

When the product 10b (indicated by a dotted line) once filled into the position at the far right of the product storage column 1 tries to drop due to the inclination or vibration of the rotary carrying member 3,
As shown in FIG. 7, the first holding member 35 is prevented from falling easily. Therefore, the products 10a and 10b are held at the positions by the first holding member 35 so as not to move.

The second holding member 3 made of a flexible material is also provided at the center of the inner surface of the left side wall 1L of the product storage column 1.
6 are positioned in the recesses 58b, extended in the up-down direction, and mounted with screws 59 with the mounting plate 60 interposed therebetween.

Since the second holding member 36 also easily bends rearward when the product is pushed in from the near side, if the product is put into the left front of the product storage column 1 and further pushed in, the product can be filled in that position as the product 10c. it can.

On the left front side of the product storage column 1, the product is inclined on the rotating carry-out member 3 toward the back, and can be filled as a product 10d simply by inserting it at this position. The product 10c and the product 10d are prevented from moving by the second holding member 36.

Reference numeral 41 denotes a commodity selling plate. When there is no commodity 10c, the spring 42 moves from a solid line position to a two-dot chain line position (41b) as shown in FIG. Since the sold-out switch operates, the presence or absence of the product 10c can be detected.

The selling operation is described below.

As shown in FIG.
When the magnet 21a comes closest, the power supply to the drive motor 13 is cut off, and the rotary carrying member 3 stops.

In the next selling operation, the power supply to the drive motor 13 is started, and the rotary carrying member 3 rotates in the direction of the arrow to carry out the product. And the magnet 21b is a reed switch 22
When the vehicle comes closest, the power supply to the drive motor 13 is cut off and stopped.

As described above, each time the rotary carrying member 3 rotates by 90 degrees, one product 10 falls. However, at this time, since the rotary carrying member 3 is inclined, for example, the product 1
0a is sold, and when there is no more product at this position, the product 10b at the back tries to move to the position of the product 10a. At this time, the movement is prevented by the first holding member 35 described above.

The sale of the product proceeds, and finally four products remain on the rotary carrying member 3. First, as shown in FIG. 8, when the product 10 a indicated by the dotted line is sold, when the product 10 a disappears, the product 1
0b slides on the inclined rotating carrying-out member 3 and the product 10
At this time, the product 10b is locked by the first holding member 35 which bends in the product pushing direction but does not move in the opposite direction, and is prevented from falling.

Thereafter, when the product 10b is delivered and then the product 10c is delivered, that is, when the product 10c indicated by the dotted line as shown in FIG.
d rolls on the product carrying member 3 and tries to drop to the product 10c. At this time, the second product holding member 36 bends in the depth direction due to a strong external force of pushing the product, but does not deform under the weight of the product itself. In this case, the second holding member 36 sufficiently prevents the product 10d from falling. .

In this way, when selling the product, it is possible to reliably prevent the product from being undesirably moved to another column storage position.

As a result, a product storage device having high product storage efficiency and easy product filling can be obtained.

[0042]

As described above, according to the product storage device of the present invention, the products can be stored in four directions around the rotary carrying member, so that the storage efficiency can be greatly improved.

The product storage structure is also a simple one having a holding member projecting inward of the product storage column so as to hold the product at the storage position, and can be provided at a low cost.

Since the predetermined holding member is made of a flexible material so as not to hinder the filling of the product, the work of accommodating the product can be facilitated.
