Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vending machine that sells beverage products in paper containers, for example.

(b) Prior Art Conventionally, as a vending machine that stores and sells beverage products in paper containers, the one shown in FIG. 1 is known. 1 is a roughly box-shaped product storage column with an opening 2 for filling products in the front; 3 is a column with its upper and lower ends rotatably supported in the upper and lower parts of the column 1; A shaft rod 5 is provided at the top of the column 1 and is continuously wrapped around the shaft rod 3.
Connect to the top end of the spiral 4 every time you sell a product.
This is a drive device that rotates 1/2 turn and controls the unloading of products from the lower end of the spiral 4. The product A to be stored and sold is to be stored between the spiral sides B on the left and right sides of the shaft 3, and such a configuration is, for example,
-74966. However, the number of products stored in such a vertical spiral system is determined by the number of spiral edges B in column 1, and due to its unique shape, the spiral edge spacing B is much larger than the size of the products to be stored. Because it requires a large space, it is unreasonable to store fewer products than the well-known serpentine and stacking vending machines.

On the other hand, as a vending machine that can increase the number of products stored, for example, as seen in Japanese Patent Laid-Open No. 52-101575, a shaft rod that rotates a predetermined amount every time a product is sold is installed vertically in the product storage column in the vertical direction. Storage chambers for stacking and storing products are provided on both sides of this shaft, and at the bottom of the shaft, by a predetermined rotation of the shaft, the lowest product in the storage chamber is sold and the next product is supported. A configuration in which an unloading mechanism is provided is known.

(c) Problems to be solved by the invention With this configuration, the number of products stored can be increased, but since many products are stacked and stored, the lower products may be deformed by the weight of the higher products. In particular, when products in paper containers are stored for sale, problems such as products near the bottom being crushed and deformed may be sold, or products may become jammed due to deformation.

For this reason, the present invention divides and supports the products to be stacked and stored, so that even if there is a large number of products to be stored and the products are easily deformed such as products in paper containers, the products can be stored securely without deformation. It provides vending machines that can sell items.

(d) Means for Solving the Problems The present invention provides a storage chamber in which a shaft that rotates a predetermined amount each time a product is sold is installed vertically in a product storage column in the vertical direction, and products are stacked and stored on both sides of this shaft. In the vending machine, the vending machine is provided with a product discharging mechanism for discharging the lowest product in the storage chamber and supporting the next product by a predetermined rotation of the shaft at the lower part of the shaft. A product delivery mechanism is provided in the vertically intermediate portion of the rod to send the product in the upper part of the storage chamber supported by a predetermined rotation of the shaft onto the product in the lower part and to support the product in the next stage of the product, This is a structure in which the products that are stacked and stored in the storage chamber are divided and stored vertically.

(e) Function A product delivery mechanism is provided in the vertically intermediate part of the shaft with a product delivery mechanism provided at the bottom, and the products to be stacked and stored in the storage chambers on both sides of the shaft are transferred to the product delivery mechanism and the product delivery mechanism. When the shaft rod rotates a predetermined amount, it sells and sends out the lowest product supported by the product delivery mechanism, and also supports the next product.At the same time as the product delivery mechanism operates, the product delivery mechanism By a predetermined rotation of the shaft rod, the lowest product supported by the product delivery mechanism is sent onto the top product supported by the product delivery mechanism, and the product next to the product is supported.

(f) Embodiments FIGS. 2 to 9 show embodiments of the present invention, and the same reference numerals as in the conventional example indicate the same or similar items. 1 has an opening 2 on the front for filling products
It is a column having a substantially U-shaped cross section with a product discharge port 6 at the lower end, and is installed vertically within the vending machine main body. Further, a support member 7 is fixed to the lower end of the column 1 in the front-rear direction so as to divide the column 1 into left and right halves, and a bearing 8 is provided at the center of the support member 7. Reference numeral 3 denotes a shaft rod whose upper end is rotatably inserted into the upper wall of the column 1 and whose lower end is rotatably supported in the bearing 8. is rotated 1/2 turn. 4
A and 4B are spirals of the same shape that are wrapped around the lower and middle parts of the shaft rod 3 by a little more than 180 degrees, and the lower spiral 4B is capable of supporting the product and serves as a product delivery mechanism for dropping the product one by one. The spiral 4A in the middle part is capable of supporting the product and serves as a product delivery mechanism for replenishing the product A from the upper storage chamber 11 to the lower storage chamber 12 divided into two by the spiral 4A. They are formed at intervals (D) narrower than the thickness (C) of product A.
Of course, the distance (E) between the shaft rod 3 and the narrow side wall 1A forming the column 1 is made slightly longer than the width (F) of the product A. In addition, the lower part of the lower storage chamber 12 is provided with the lowest product A, which is wider than the upper storage space.
The escape space 9B of 1 is formed by the stepped portion 10B of the side wall 1A, and the escape space 9A that makes the lower storage space wider than the upper storage space is also formed at the lower part of the upper storage chamber 11 by the stepped portion of the side wall 1A. 10A. Moreover, the shortest distance (G) between the spirals 4A and 4B is set to be narrower than the thickness (C) of the product A, so that the product A does not fall at any time except when being carried out. Furthermore, Figures 4 and 5
As shown in the figure, the drive motor 5 moves the shaft rod 3 by 90 degrees.
The spirals 4A and 4B are arranged so that the right product group in column 1 does not fall together with the lowest products A1 and A11 when rotated.
It is wrapped around 180 degrees or more, and the upper end protrudes on the opposite side with the shaft rod 3 in between. As shown in Figure 4, this protrusion dimension (H) is the distance between the shaft rod 3 and the side wall 1A at the narrow part when the shaft rod 3 is rotated 90 degrees.
Greater than the difference obtained by subtracting the width (F) of product A from (E),
Further, the stepped portion 1 forming the escape spaces 9A and 9B
This is taken to be smaller than the difference obtained by subtracting the width (F) of product A from the distance (I) between the side wall 1A and the upper ends of the spirals 4A and 4B in the wide part expanded by 0A and 10B. In other words, each lowest product A at the time of delivery
1, A11 is pushed outward by the upper ends of spirals 4A and 4B, and then the product A1
1 is delivered to a lower storage chamber 12 by falling, and the product A11 is carried out, and the products in the next stage are supported by the upper ends of spirals 4A, 4B and the narrow side wall 1A, and are formed to prevent them from falling.

Although not shown, the opening 2 of the storage column 1
is opened and closed by a movable product fall prevention lever, and since this is a commonly available means, it will be omitted here. Further, although the number of spirals 4A wound around the middle portion of the shaft rod 3 is set at one location in this embodiment, it goes without saying that the number of spirals 4A may be increased as needed.

The operation of the above configuration will be explained below.
First, FIGS. 2 and 3 show a sales standby state, in which the long diameter portions of the spirals 4A and 4B support the product groups in the respective storage chambers 11 and 12 in the left and right direction. When a predetermined coin is inserted and a predetermined operation related to sales is performed, the drive motor 5 is energized and the shaft rod 3 is rotated 180 degrees, but the longer diameter portion of the spirals 4A and 4B is 90 degrees in the front-rear direction. The operation at the time of rotation is shown in FIGS. 4 and 5. That is, the lowest products A11 and A1 supported on the lower ends of spirals 4A and 4B, respectively.
are pushed outward by the upper ends of the spirals 4A and 4B as the shaft rod 3 rotates.
At this time, the protruding dimension (H) of the spirals 4A, 4B is determined from the distance (I) between the side wall 1A and the top end of the spirals 4A, 4B at the wide part widened by the stepped portions 10A, 10B, and the width (F) of the product A. ), each of the lowest products A11 and A
1's bearing came undone, product A1 fell and was carried out,
It reaches a sales outlet (not shown). Further, the product A11 in the upper storage chamber 11 falls into the lower storage chamber 12, and is delivered onto the product A9 in the lower storage chamber 12 to be replenished. At this time, the top product A
13 and A3 are supported by the side wall 1A at the narrow portion and the upper ends of the spirals 4A and 4B, thereby preventing double sales. When the shaft 3 further rotates 90 degrees, the 6th
In the state shown in FIG. 7 and FIG. 7, the left and right product groups are supported with the long diameter portions of the spirals 4A and 4B oriented in the left and right direction, and are in a standby state, thus completing one sales operation.

In the next selling operation, the products A12 and A2 placed in the lowest position fall away from the spirals 4A and 4B, respectively, when the shaft rod 3 rotates approximately 90 degrees, as described above. As shown in FIGS. 8 and 9, the product A12 in the upper storage chamber 11 falls onto the product A10 in the lower storage chamber 12 and is replenished, and the product A2 in the lower storage chamber 12 falls and is carried out. be done. Then, it rotates another 90 degrees and returns to the state shown in FIGS. 2 and 3, again returning to the standby state. In this way, the axis rod 3 becomes 180
One sales operation is performed each time the machine rotates, and one product is delivered to the left and right alternately.

(g) Effects of the Invention As described above, the present invention has a product storage column in which a shaft that rotates a predetermined amount each time a product is sold is installed vertically in the vertical direction, and storage chambers for stacking and storing products are provided on both sides of this shaft. In the vending machine, the vending machine is provided with a product carry-out mechanism for dispensing the lowest product in the storage chamber and supporting the next product by a predetermined rotation of the shaft at the lower part of the shaft. A product delivery mechanism is provided in the vertically intermediate portion of the storage chamber for delivering the product in the upper part of the storage chamber supported by a predetermined rotation of a shaft rod onto the product in the lower part and supporting the product in the next stage of the product. This is because products that are stacked indoors can be stored vertically.
Even if the number of products stacked and stored in a product storage column is large, the product load applied to the lowest order product can be reduced. Therefore, the product does not become deformed, and there is no possibility of delivery failure due to product deformation, making it extremely effective as a vending machine for storing and selling beverage products in paper containers that are relatively easily deformed. .
