DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine having a transparent visible plate door for displaying and selling products such as canned beverages, beverages in paper packs, tobacco and snacks in a plurality of rows and in multiple stages. The present invention relates to an unloading device.

[0002]

2. Description of the Related Art Conventionally, a vending machine having a product rack for storing products in a horizontal arrangement has been known, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 62-44379.

FIG. 11 shows a conventional product unloading device of a vending machine provided with a product rack for horizontally storing products in a horizontal manner. An individual conveyor device 27 for sending out products 26 to a product rack 25 in a horizontal direction and a driving device The part is fixed.

[0004]

However, in the above-mentioned conventional configuration, it is necessary to provide a product stopper opening / closing device, a stopper opening / closing drive unit, a product transport device and a transport drive unit in each of all product racks. In a vending machine in which racks are arranged, there is a problem that the number of driving units is very large and the cost is high.

Further, since the product rack is fixedly provided with the opening / closing device for the product stopper, the drive unit, and the product transport device and the transport drive unit, the product rack cannot be pulled out when the product is stored, so that the product storage property is poor. There was a problem.

Further, when the product rack including the transport drive unit is pulled out, it is necessary to move the electric wiring, which increases the cost because the wiring has mobility.
There is a problem that the failure of the movable part increases.

The present invention has been made to solve the above-mentioned conventional problems. One transport drive unit drives two product transport devices, and the number of drive units can be reduced by half. The purpose is to provide an unloading device.

Another object of the present invention is to switch and connect the product transport device and the transport drive unit in conjunction with the opening and closing operation of the product stopper opening and closing device, and to connect the product transport device and the transport drive unit by opening the product stopper. By doing so, there is no need to set complicated operation timings at the time of selling the product or to perform complicated electrical control at all, and to make the operation simple and compact.

Another object of the present invention is that when the connection between the left and right moving bodies for connecting the transport drive unit is unstable, the elastic body in the axial direction temporarily absorbs the binding force, and is transferred from the transport drive unit to the product transport device. The power transmission ensures reliable connection.

Another object of the present invention is to reduce a wiring cost and wiring failure by separating a transport drive unit having control wiring to a product storage side when a product rack is pulled out at the time of storing a product or the like. It is in.

Another object of the present invention is to provide a structure in which the gears of the left and right moving bodies of the product rack are separated from the drive gear of the product storage when the product rack is pulled out, and are switched to the two product transport devices when the product is sold. Is simplified, and the cost is reduced.
