It is being energized.
[0012]
[Action]
With this configuration, the plurality of movable traveling members arranged opposite to the plurality of arc-shaped fixed traveling members arranged in the vertical direction between the two opposing side plates are provided with shaft portions formed on both sides of the upper end thereof. Can be rotatably attached to the side plate by passing through the side plate. Then, these movable traveling members can be urged in the direction toward the fixed traveling member by a coil spring wound around the shaft portion with one end locked and the other end locked to the side plate.
[0013]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a side sectional view of a product storage device of a vending machine according to one embodiment of the present invention. 5, the same reference numerals as those in FIGS. 5 and 6 denote the same or corresponding parts.
[0015]
In the figure, reference numeral 8 denotes a merchandise storage shelf device in which a merchandise passage R having a serpentine structure is formed in close contact in the front-rear direction. The guide plate is provided between the insertion port 9 and the entrance of the product passage R and is movable in the front-rear direction. In addition, in the figure, only the product path R in the last row of the product storage shelf device 1 is shown.
[0016]
Reference numeral 11 denotes a fixed wall portion which is provided at a lower end portion of the product passage R and houses therein a product discharging device for sequentially discharging stored products one by one, and 12 faces the fixed wall portion 11. An outlet regulating plate that is arranged and supported so as to be movable in the front-rear direction, and regulates the width of the product outlet 13 formed together with the fixed wall portion 11.
[0017]
By the way, reference numeral 14 denotes a movable traveling member. The movable traveling member 14 is formed by curling the upper end of a shaft portion 15 inserted into the side plate 4 on both sides of the upper end as shown in FIG.
[0018]
The movable traveling member 14 is wound around the product passage R with one end 16a being locked to one shaft portion 15 from the outside of the product passage R, and the other end 16b is fixed to a locking hole 4a formed in the side plate 4, for example. Are biased in the direction toward the fixed traveling member 7 by the coil spring 16 locked at the position.
[0019]
A notch 15a is formed at the tip of the shaft portion 15, for example, as shown in FIG. 3, and one end 16a of the coil spring 16 is connected to the notch 15a as shown in FIG. The shaft portion 15 is wound around in a state of being locked by the restoring force of the shaft 16 itself.
