Abstract

PURPOSE:To prevent a commodity from being suppressed in its movement and run on a support metal by abutting it on a guide pin at the time of carrying it, by projecting two front and rear guide pins approximately conically formed on the upper face of the upper end of the support metal. CONSTITUTION:A rack case 2 is provided with the support metal 4 running between the front and rear sides of the case 2 so as to divide a lower face carry-out end part into two right and left parts and the guide pins 11 formed like approximately conical shapes are projected on the upper face so as to be located on the front and rear outsides with a bearing 5 between. In this constitution, a commodity 10 carried out downwards by a selling signal receives force for moving it to the upper part of the support metal 4 in the arrow B direction by frictional force with a spiral wire 7 rotated in the arrow A direction. However the right and left sides of the commodity 10 are abutted on the front and rear guide pins 11 before the metal 4 and suppressed in its movement, so that the commodity 10 is normally dropped along the peripheral faces of the pins 11. Thereby even when frictional force with the wire 7 is applied to the commodity 10, the commodity 10 can surely be dropped and carried out without being locked on the metal 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to vending machines,
The present invention relates to a spiral wire-type product storage rack in which a spiral wire is provided in a rack case, products are stored by being supported by the spiral wire, and the products are sequentially dropped and carried one by one by the rotation of the spiral wire according to a sales signal.

[0002]

2. Description of the Related Art As this type of product rack, the one shown in FIGS. 9 to 11 is known. In the figure, a product rack 1 includes a box-shaped rack case 2 having an opening on the lower surface and the front surface. The rack case 2 is provided with a door 3 at the front opening, and the lower surface opening is provided at the lower end which is the carrying-out end of the product.
A support metal 4 is provided which runs back and forth in the center of the bearing, and a bearing 5 is disposed in the center thereof. Inside the rack case 2, a spiral wire 7 is installed, which is fixed to the central rotating shaft 6 at appropriate intervals and extends vertically around it in a spiral shape.
A lower end of the rotary shaft 6 is rotatably supported by the bearing 5, and an upper end thereof is connected to an output shaft of a drive motor 8 installed on the top plate of the rack case 2.

In the product rack 1, products 10 are supported by a spiral wire 7 and are stored in a rack case 2 arranged vertically in two rows. However, the spiral wire 7 is rotated by 180 ° by the operation of the drive motor 8 in response to the sales signal and the products are simultaneously lowered, and the products 10 in the lowermost stage lose the support of the spiral wire 7 and are alternately left and right one by one. Dropped out and delivered to the product outlet of the vending machine.

[0004]

By the way, when the product 10 is lowered and conveyed by a sales signal, the product 10 receives a force to move in the rotational direction of the spiral wire 7 due to a frictional force with the spiral wire 7. In the conventional product rack 1, as shown in FIG. 12, the product 10 having received the force is supported on one end thereof and rides on the metal 4 to stop the transportation, and the vending machine may be unable to sell.

It is an object of the present invention to provide a spiral wire type product rack in which products can be transported reliably and troubles in which vending machines cannot be sold can be avoided.

[0006]

To achieve the above object, according to the present invention, as an example, the upper end is driven in a box-shaped rack case having a bottom opening as a carry-out port and a front opening having a door. A spiral wire whose lower end is rotatably supported is mounted on a bearing provided on a support bar that is connected to the motor and is fixed to the rack case and extends in the front-rear direction. The spiral wire is supported by the spiral wire and is vertically supported in two rows. In the spiral wire type product rack of the vending machine in which the products stored side by side are simultaneously lowered by the rotation of the spiral wire, and the products at the lowermost stage are sequentially dropped and carried out, the products to be lowered and transported are the support bars. A guide pin for preventing the rider from riding on is to be provided on the upper end surface of the support bar so as to project therefrom.

[0007]

The product which is about to be moved in the direction of rotation of the spiral wire during transportation is brought into contact with the guide pin to suppress its movement and is prevented from riding on the support bar. Therefore, the product descends normally and is surely dropped and carried out.

[0008]

1 to 3 show a first embodiment of the present invention, in which parts common to or the same as those in FIGS. 9 to 11 are designated by the same reference numerals. 1 to 3, the rack case 2 is provided with a support bar 4 that runs forward and backward so as to divide the lower surface carrying-out end portion into left and right parts. Reference numeral 11 is a guide pin according to the present invention. The guide pin 11 is formed in a substantially conical shape, and two guide pins 11 are provided on the upper end surface of the support bar 4 and in front of and behind the bearing 5 so as to project outward.

In the above-described structure, the commodity 10 conveyed downward by the sales signal receives the force of moving above the support bar 4 in the direction of arrow B due to the frictional force with the spiral wire 7 rotating in the direction of arrow A. However, the product 10 comes into contact with the front and rear guide pins 11 in front of the support bar 4 on the left and right sides to stop the movement, and normally descends along the outer peripheral surface of the guide pin 11. Therefore, the product 10 is reliably dropped and carried out without being locked by the support bar 4 on the way.

A second embodiment of the present invention will be described with reference to FIG. In FIG. 4, the front and rear ends of the rack case 2
Is secured to the bearing and supports the rotating shaft with the bearing 5 in the center.
Is installed in an oblique direction by rotating the spiral wire 7 by an appropriate angle θ with respect to the center line 15 in the front-rear direction. In the above configuration, the commodity 10 (FIG.
0) is moved in the rotational direction by the frictional force with the spiral wire 7 and approaches the support bar 4, but the space of this portion is formed large by the above-mentioned configuration of the support bar 4,
Moreover, when the product 10 comes into contact with the support bar 4, the product 10 is further lowered than before, so that it is possible to avoid riding on the support bar 4. Therefore, the product 10 is normally lowered and carried out.

A third embodiment of the present invention will be described with reference to FIGS. 5 to 8, a supporting bar 4 having a bearing 5 in the center and extending in the front-rear direction has a leg 4a which is bent in the opposite direction between the bearing 5 and the rear inner surface and the front surface of the rack case 2 and extends laterally. It is formed and is fixedly supported by the side plates of the rack case 2 at both ends thereof. Therefore, a space is formed between the front and rear inner surfaces of the rack case 2 and the legs 4a of the support bar 4 so as to connect to the entire lateral width of the rack case 2. In the above-described configuration, when the product 10 is being lowered and conveyed, FIG.
As shown in Fig. 1, the point 1 where it is easy to get caught in the support bar 4 of the product 10.
Since there is no support money in 0a and it is a space, the product 10 can be carried out without trouble. In particular, when a part 10a of a container of a product such as the product 10 shown in FIG. 13 is bulged or peeled off, a carry-out trouble often occurs in the past, but such a product 10 is mixed. Even with the above configuration, trouble can be avoided. Further, as shown in FIG. 8, the lowermost product 10 loses support of the spiral wire when the product is unloaded, and at the same time, the legs 4 on the front and rear sides of the supporting bar 4
It is rotated downward by its own weight around a as a fulcrum, falls from the rack case 2, and is more reliably carried out.

[0012]

According to the present invention, as an example, the upper end is connected to the drive motor in a box-shaped rack case having a lower opening as a carry-out port and a front opening having a door.
A spiral wire whose lower end is rotatably supported is installed on a bearing provided on a support bar which is fixed to the rack case and extends in the front-rear direction, and products which are supported by the spiral wire and are vertically arranged in two left and right rows are stored. In a spiral wire type product rack of a vending machine in which the lowermost products are sequentially dropped and carried out by rotation of the spiral wire, a guide for preventing the descended products from riding on the support bar. Since the pin is provided so as to project on the upper end surface of the support bar, the goods conveyed downward by the sales signal will surely descend without being ridden on the support bar even if it receives frictional force with the spiral wire, and will be dropped out. It Therefore, the concern that the vending machine cannot be sold is eliminated.
