DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vending machine,
A spiral wire is provided in the rack case, the product is supported by the spiral wire, and the product is stored therein.
The present invention relates to a spiral wire type product rack that is individually dropped and carried out.

[0002]

2. Description of the Related Art As this kind of product rack, the one shown in FIGS. 5 to 7 is known. In the figure, a product rack 1
Comprises a box-shaped rack case 2 whose lower surface and front surface are open. The rack case 2 is provided with a door 3 at the front opening, and at the lower end serving as a carry-out end of the product, a support 4 running back and forth in the center so as to divide the lower opening into two parts. 5 are provided. Inside the rack case 2, a spiral wire 7 fixed to a central rotating shaft 6 at an appropriate interval and spirally extending vertically around the center is installed, and the lower end of the rotating shaft 6 is rotatably mounted on the bearing 5. It is supported and the upper end is connected to the output shaft of the drive motor 8 installed on the top plate of the rack case 2.

[0003] The product rack 1 has a product 10 supported by a spiral wire 7 and housed in a rack case 2 side by side in two rows. When the drive motor 8 is operated by the sales signal, the spiral wire 7 rotates 180 ° at a time, and the products descend at the same time.
Loses the support of the spiral wire 7 and alternates 1
They are individually dropped and carried out, and sent out to the product outlet of the vending machine.

[0004]

By the way, when the product 10 is conveyed downward by the sales signal, the spiral wire 7 is moved.
And a force to move in the rotational direction of the spiral wire 7 due to the frictional force with the spiral wire 7. In the conventional product rack 1, as shown in FIG. 8, the product 10 receiving the force may ride on the support 4 at one end, stop the conveyance, and the vending machine may not be able to sell.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a spiral wire type product rack in which a product can be reliably carried out and a trouble that a vending machine cannot be sold can be avoided.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a box-shaped rack case having a lower opening as a carry-out port and a door at a front opening, the upper end of which is connected to a drive motor. A spiral wire having a lower end rotatably supported by a bearing provided at substantially the center of a support bar having both ends fixed to the rack case is installed. The spiral wire is supported by the spiral wire and arranged vertically in two rows on the left and right. In the spiral wire type product rack of the vending machine in which the stored products are simultaneously lowered by the rotation of the spiral wire and the products at the bottom are sequentially dropped and carried out, the support bar and the front and rear legs are separated from the spiral wire. Formed in a Z-shape so as to cross the end of the product to be ejected and to be arranged with an appropriate distance between the front and rear legs and the front and rear inner surfaces of the rack case , Characterized by being adapted to abut against falling back and forth of the leg ends are supported gold product discharged from the spiral wire.

[0007]

In the spiral wire type product rack of the vending machine of the present invention configured as described above, the product moved in the rotating direction of the spiral wire during the downward conveyance is:
Since the legs of the supporting member are arranged at an appropriate distance from the front and rear inner surfaces of the rack case, they can be reliably dropped and carried out without climbing on the supporting member. At the time of the drop-out, the product abuts on one end side against the legs of the support bar, and falls so as to rotate with the contact point as a fulcrum, whereby the falling posture is controlled to a constant posture.

FIGS. 1 to 4 show an embodiment of the present invention, in which the same reference numerals are given to the same or the same parts as those of the conventional example shown in FIGS. 1 to 4, a support 4 having a bearing 5 at the center and extending in the front-rear direction.
The leg 4a is formed between the bearing 5 and the rear inner surface and the front surface of the rack case 2 so as to bend in opposite directions and extend laterally, and both ends thereof are fixedly supported by the side plates of the rack case 2. Accordingly, a space is formed between the front and rear inner surfaces of the rack case 2 and the legs 4 a of the support bar 4 so as to extend over the entire width of the rack case 2. In such a configuration, the product 1
As shown in FIG. 3, the product 10 can be carried out without any trouble because there is no space for the support 4 at the portion 10a where the product 4 is easily caught by the support 4 as shown in FIG. In particular, in the case where a portion 10a of a product container has protruded or peeled off as in a product 10 shown in FIG.
Even if 0s are mixed, troubles can be avoided by the above configuration. Further, as shown in FIG. 4, the lowermost product 10 loses the support of the spiral wire when the product is carried out, and the lower case 10 is rotated downward by its own weight with one of the legs 4a before and after the support bar 4 as a fulcrum. 2 and fall out more reliably.

[0009]

As explained above, according to the present invention,
In a box-shaped rack case having a lower opening as a carry-out port and a door at a front opening, the upper end is connected to a drive motor, and both ends are provided substantially at the center of a support bar fixed to the rack case. A spiral wire whose lower end is rotatably supported on the bearing is installed, and the products supported by this spiral wire and stored vertically in two rows on the left and right are simultaneously lowered by the rotation of the spiral wire, and the lowermost row is In a spiral wire type product rack of a vending machine in which products are sequentially dropped and carried out, in the vending machine, the supporter traverses the front and rear legs across the ends of the product discharged from the spiral wire and the front and rear both legs and the front and rear inner surfaces of the rack case. Are formed in a Z-shape so as to be placed at an appropriate interval between the spiral wire and the end of the product discharged from the spiral wire is attached to the legs in front and behind the support bar. By dropping in contact with the product, the product that is carried down by the sales signal receives the frictional force with the spiral wire and moves down in the direction of rotation of the spiral wire without falling on the support bar without fail. Is done. In addition, the product carried out of the rack case is rotated around the legs of the support bar and falls, whereby the carrying-out posture of the product is always controlled to be constant, and the product carried out by dropping is stably used in the vending machine. It can lead to the product exit.
