Abstract

PURPOSE:To improve the housing efficiency of conical-shaped merchandise by adjusting the pitch of spirals arranged on the column side of a small frontage housing the large dimension part in the direction of inner part to the maximum dimension of the merchandise and setting the pitch of the spiral arranged on the column side of a large frontage housing the small dimension part of the merchandise smaller than the maximum dimension of the merchandise. CONSTITUTION:A column partition wall 3 is installed in front of and behind of a case diagonally, and on both sides in the case, columns 4 and 5, whose sectional forms are respectively formed to be trapezoids, are divided in contrast each other by the partition wall 3. A spiral pitch P1 of a spiral 7 arranged inside the column 5 is set to the pitch corresponding to the maximum dimension of merchandise 9, and a spiral pitch P2 of a spiral 6 is set to be smaller than the spiral pitch P1 and to be corresponded to the central section dimension in longitudinal direction of the merchandise 9. Thus, the merchandise with tapered-shape like conical shape can be efficiently housed, and the housing efficiency of merchandise can be improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a spiral product storage system for a vending machine that sells conical or similar tapered products such as cone-shaped ice cream. Regarding the rack.

(Prior art) As a product storage rack for a vending machine, a spiral type is used in which a rotating spiral with a vertical shaft connected to a bend motor is installed in a rack case, and products are inserted and supported from the front into the pitch gap of the spiral to sell them. Product storage racks are well known.

On the other hand, as a spiral product storage rack for selling products with a conical shape or a similar tapered shape, such as cone-shaped ice cream, the column of the rack case is designed to reduce the width of the rack case. It is known that the spiral is installed with a bias toward either the left or right direction, and the products to be inserted and supported in the spiral are arranged in two rows on the left and right so that the orientations of the products are alternated in the longitudinal direction. (Japanese Unexamined Patent Publication No. 51-186090) [Problems to be Solved by the Invention] However, the above-described structure of the spiral type product storage rank is still insufficient in terms of product storage efficiency.

In other words, in order to insert products into one spiral in a staggered manner by distributing them to the left and right, the spiral should be inserted at least to the maximum diameter of the products (in one row, the products should be inserted with the large diameter part facing toward the back). It is necessary to set it to a corresponding pitch.

On the other hand, when a conical product is stored in a rack, the central portion, which has a smaller diameter than its maximum diameter, is stored in a spiral shape. Therefore, there is no need to expand the spiral pitch to the maximum diameter of the product, especially for products that are inserted with the small diameter part toward the back, and with the above configuration, there will be an extra gap between the spiral pitches when the product is stored. will be born.

For this reason, it is not possible to make the most effective use of the space inside the refrigerator in terms of product storage efficiency.

The present invention was developed in consideration of the above points, and aims to eliminate wasted space in the product storage rack as much as possible and make the most effective use of the space inside the product storage rack for products with a conical or similar tapered shape. To provide a spiral type product storage rack for a vending machine, which improves product storage efficiency.

[Means to solve the problem]

In order to solve the above problems, the spiral type product storage rack of the present invention has a case with a front door having a square cross section.
A column partition wall in the front and rear diagonal directions is installed in the center of the case to define two columns with a trapezoidal cross section, alternating left and right.A spiral is placed in each column, and the large diameter part of the product is Match the pitch of the spiral placed on the column side with a small frontage that accommodates the product toward the back to match the maximum diameter of the product, and adjust the pitch of the spiral placed on the side of the column with a large frontage that accommodates the small-diameter portion of the product toward the back to match the maximum diameter of the product. It shall be set smaller than the maximum diameter of.

[Effect]

With the above configuration, the spiral placed on the column side with a large frontage, which accommodates the small-diameter part of the product toward the back, can accommodate the product at high density without leaving any unnecessary gaps between the spiral pitches. Therefore, the number of products stored in the product storage rack as a whole increases, that is, the product storage efficiency improves accordingly. Furthermore, within the rack case with a rectangular cross section, two columns with a trapezoidal cross section that match the external shape of the product are arranged in alternating directions to define the rack case. can be configured by minimizing the width dimension.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

First, the overall structure of the rack will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is an open-front product storage rack case with a rectangular cross section, 2 is the front door of case l, 3 is a column partition wall installed in the center of the case, and 4.5 is a partition wall 3.
Product storage columns defined on the left and right inside the case through
6 and 7 are vertical rotating spirals arranged inside each column 4 and 5, 6a and 7a are rotating shafts of the spirals 6 and 7, 8 is a bend motor connected to the spiral shaft 7,
9 is a spiral 6゜7 deployed in each column 4.5
In contrast, cone-shaped products were stored in two rows on the left and right (
It is a cone-shaped ice cream with a stick.

Here, as clearly shown in FIG. 1, the column partition wall 3 is installed obliquely in the front and rear.
Columns 4.5 each having a trapezoidal cross-sectional shape are defined in alternating directions on the left and right sides of the case. That is, column 4 on the left side has a wide frontage and narrow depth, while column 5 on the right side has a narrow frontage and widened depth, and the spiral 6.7 is inside columns 4 and 5 in the front-rear direction. They are placed at different locations. The product 9 is stored in the column 4 with the small diameter portion facing toward the back.
On the other hand, it is housed from the front of the case 1 with the large diameter portion facing towards the back.

In addition, regarding the above-mentioned spiral 6.7, Figures 3 and 4
Spiral 7 deployed in column 5 as detailed in the figure.
The spiral pitch Pi is set to a pitch corresponding to the maximum diameter of the product 9.

On the other hand, the spiral 6 arranged in the column 4 has a spiral pitch P2 equal to the spiral pitch Pi.
It is set to correspond to the central cross-sectional diameter of the product 9 in the longitudinal direction.

In order to replenish the products 9 into the rack case l with this configuration, each column 4 is inserted from the front of the case with the front door 2 open.
．． Product 9 is placed in the pitch gap of spiral 6.7 deployed in 5.
Insert it in the specified direction.

In this case, the pitch P2 of the spiral 6 is set to be smaller than the maximum diameter of the product 9, especially in the left column 4 (which houses the product 9 with the small diameter part toward the back), and therefore the right column 5 (Store product 9 with the large diameter part toward the back)
It can accommodate a larger number of products compared to . Moreover, the columns 4.5 have a trapezoidal cross section that matches the external shape of the product 9, and are defined inside the rack case 1 by overlapping each other in alternate directions, so there is no unnecessary blind space inside the rack case. This does not occur, and the width of the entire rack case can be minimized.

〔Effect of the invention〕

As described above, according to the configuration of the spiral product storage rack of the present invention, it is possible to efficiently store products in a conical shape or a similar tapered shape by eliminating wasted space in the product storage rack case. Accommodation efficiency can be improved.
