Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a spiral wire type product storage shelf for a vending machine that is provided with an upright spiral wire in the product storage chamber.

[Conventional technology]

The spiral wire type product storage shelf shown in FIG. 1 is used in a vending machine that sells cylindrical cup products and is already well known. In Fig. 1, reference numeral 1 denotes a product storage room partitioned by thin iron plates with openings on the front and bottom surfaces, 2 a drive motor supported on the ceiling wall of the product storage room 1, and 3 a drive motor at the upper end. A rotating shaft is directly connected to the output shaft of the motor 2 and extends vertically into the product storage chamber 1. The lower end of the rotating shaft 3 is supported by a bearing attached to the frame plate 1a at the lower front of the product storage chamber 1. Reference numeral 5 denotes a spiral wire formed using a wire such as a hard steel wire, and the spiral wire 5 is arranged so that the rotating shaft 3 passes through its center, and both ends are connected to each other via support arms 6 and 7. and is fixed to the rotating shaft 3. The support arms 6 and 7 extend in the radial direction of the spiral wire 5, and have one end attached to the rotating shaft 3 by welding at right angles, and the other end fixed to the spiral wire 5 by welding. Spiral wire 5 fixed in this way and product storage chamber 1
There is usually a gap of around 10 mm between the inner surface of the side wall and the inner surface of the side wall. 8 is a product stored so as to be held by the spiral wire 5, 9 is a product 8
This product guard is provided along the front surface with both upper and lower ends locked to the ceiling wall and frame board of the product storage room 1 to prevent the products from falling off. When storing the product, the product guard 9 is moved left and right to open the front side.

The above-mentioned product storage shelf stores products 8 in two rows on the left and right across the rotating shaft 3 within the helical space of the spiral wire 5.
is stored. Then, the spiral wire 5 is rotated by 180 degrees by the drive motor 2 which rotates in response to a sales command, and the products 8 are sent downward, and the products at the bottom are sequentially sent out from the bottom opening toward the product takeout port.

[Problem that the invention attempts to solve]

However, in the above-mentioned product storage shelf, as shown in FIGS. 2 and 3, when the support arm 7 approaches the product 8 from above and comes to a position facing approximately in the front-back direction, the support arm 7 moves toward the product 8. 8, and there was a risk that the product 8 would be damaged due to this interference. In addition, in order to avoid this danger, the pitch of the spiral wire 5 must be increased, which has the disadvantage that the number of products 8 to be stored is reduced.

The object of this invention is to provide a spiral wire type product storage shelf for a vending machine that eliminates the above-mentioned drawbacks and prevents products from being damaged due to interference from the support arm.

[Means for solving problems]

In order to achieve the above object, this device is equipped with a spiral wire that revolves around a rotating shaft that extends vertically in a product storage chamber, and the product held in the spiral space of the spiral wire is sent downward by the rotation of the spiral wire. In the spiral wire type product storage shelf of the machine, the spiral wire is fixed to the rotating shaft via a support arm that has one end fixed to the spiral wire and the other end fixed to the rotating shaft, and the support arm is fixed along the spiral wire. Together, they are formed into a spiral shape.

[Effect]

According to this invention, a cylindrical cup product can be smoothly transported by a support arm formed in a spiral shape along a spiral wire.

〔Example〕

Examples of this invention will be described below based on the drawings. In the figures, parts common or identical to those in FIGS. 1 to 3 are designated by the same reference numerals.

In FIGS. 4 and 5, support arm 10
The support arm 10 has one end welded to the spiral wire 5 and the other end welded to the rotating shaft 3.
is attached inside the spiral wire 5 along the helix of the spiral wire 5.

Therefore, as shown in FIG.
Even if the support arm 1 is located above the product 8,
0 is provided along the spiral wire 5 so that it does not interfere with the product.

[Effect of idea]

According to this invention, the support arm that supports the spiral wire is formed into a spiral shape along the inside of the spiral wire, so that the cylindrical cup product can be easily carried out and damage to the product can be prevented.
