Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product storage device used in an automatic vending machine for beverages in cans or bottles.

[0002]

2. Description of the Related Art Conventionally, as a vending machine of this type, products are stacked and stored in a plurality of vertically extending product passages, and they are dropped and carried out one by one from the lower end of the product passages. Most of them are the mainstream, but recently, as an indoor type vending machine, the actual application is 3-105.
The one described in No. 616 is also proposed.

In this vending machine, as shown in FIG. 6, inside a vending machine body 1 whose upper surface is openable and closable, a product container 2 having an opening for product insertion on the upper surface, and a product container 2
A pair of upper and lower sprockets 3 and 4 arranged on one side surface of the
An endless chain 5 attached to each sprocket 3, 4 and a plurality of push-up members 6 attached to the chain 5.
And a chain drive motor 8 connected to the lower sprocket 4 via a belt 7 for raising the commodity A stored in the commodity container 2 by the push-up members 6. Then, the product is sequentially carried out to the product outlet 1a provided on the front surface of the vending machine body 1.

[0004]

However, in the above-mentioned conventional example, since the push-up members 6 attached to the chain 5 have a structure of raising the inner side of the product container 2 and lowering the outer side thereof, There has been a problem that the operating range of the member 6 is increased in the front-back direction of the product container 2 and the capacity of the product container 2 is reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the operating range of the push-up member in the front-rear direction of the product container so that the capacity of the product container can be increased. To provide a storage device.

[0006]

In order to achieve the above-mentioned object, the product storage device of the present invention has a product container having an opening for product insertion on the upper surface, and extends vertically along the front surface of the product container. It is provided with a spiral member, a product push-up member that is screwed into the spiral member, and a drive unit that raises and lowers the product push-up member by rotating the spiral member.

[0007]

According to the commodity storing apparatus of the present invention, the commodity pushing member is screwed to the spiral member extending in the vertical direction along the front surface of the commodity container to move up and down. It becomes smaller in the front-back direction of the product container.

[0008]

1 to 5 show an embodiment of the present invention. This product storage device is provided in the same vending machine body as in the conventional example, has a product container 10 having an opening for product insertion on the upper surface, and a shaft 20 with a screw attached to the front side of the product container 10. A push-up member 30 for carrying out a product, which is screwed into the threaded shaft 20, and the threaded shaft 2.
It is composed of a geared motor 40 for rotating 0 and a product release mechanism 50 provided on the front side upper part of the product container 10.

As shown in FIG. 1, the product container 10 has a front surface and an upper surface opened, and the product A can be stored in bulk through an opening 10a on the upper surface which serves as a product insertion port. Inside the product container 10, a bottom plate 11 inclined forward and downward is attached like a raised bottom, and a notch 11a is formed at the front end of the bottom plate 11 to allow passage of a push-up member 30 described later. A front plate 12 extending upward from the front end of the bottom plate 11 is provided on both side surfaces of the product container 10 with a slight forward inclination, and the gap between the front plates 12 is equal to the width of the cutout 11a. There is.

The threaded shaft 20 is arranged in front of the front plate 12, extends vertically along the front plate 12, and has its lower end connected to the rotary shaft of the motor 40.

The push-up member 30 is formed in a plate shape as shown in FIG. 2, and the tip end thereof is bent slightly upward. The lower surface of the push-up member 30 has two mounting pieces 30 protruding downward.
a are formed at intervals in the width direction, and each mounting piece 30a is rotatably connected to a slider 31 screwed to the threaded shaft 20 via a shaft pin 32. Further, as shown in the bottom view of FIG. 3, a notch 30b is formed at the center of the push-up member 30 in the width direction, and the notch 30b allows the threaded shaft 20 to be inserted therein without resistance. That is, the push-up member 30 can be rotated upward to the position shown by the alternate long and short dash line in FIG. 2, and at the lower position, it is held substantially horizontally by the contact with the upper surface of the slider 31 as shown by the solid line. The angle θ1 formed by the upper surface of the push-up member 30 and the threaded shaft 20 at the lower position is 70 °.
To 90 °, the bending angle θ2 of the tip of the push-up member 30 is 5 °.
It is suitable that each is set to -40 °.

The geared motor 40 is designed to be capable of normal rotation and reverse rotation, and is installed on the bottom of the product container 10.
The rotating shaft is connected to the lower end of the threaded shaft 20. The motor 40 is connected to a micro switch 41 arranged above the product container 10,
When the commodity A on the ascending push-up member 30 comes into contact with the contact 41a, the operation of the motor 40 is stopped.

The product locking mechanism 50 is composed of a carry-out element 51 that locks the product A on the push-up member 30 and a solenoid 52 that moves the carry-out element 51 up and down. 52 operates to release the product A held on the carry-out piece 51 to the front of the product container 10.

The commodity storage device configured as described above is
Although not shown, a plurality of vending machine main bodies are provided in the width direction so that different types of products can be stored. That is, when a product selection button (not shown) is pressed, the product locking mechanism 50 operates, and the product A on the push-up member 30 rolls and drops in front of the product container 10 and is carried out to a product outlet (not shown). At this time, since the carried-out product A is separated from the micro switch 41, the motor 40 operates and the shaft 20 with a screw rotates. As a result, the slider 31 follows the rotation of the threaded shaft 20 and the push-up member 30 descends. At that time, although the push-up member 30 hits the product A in the descending path, when the push-up member 30 hits the product A, the push-up member 30 rotates upward as shown in FIG. 5 and descends without being caught by the product A. When the push-up member 30 reaches below the bottom plate 11, the push-up member 30 returns to the horizontal state and rises again due to the reverse rotation of the motor 40. As a result, one of the products A on the front side in the product container 10 is placed on the push-up member 30 and ascended, and when the product A comes into contact with the contact of the micro switch 41, the motor 40 is stopped. Then, the product A is restrained by the product locking mechanism 50 and stands by until the next carry-out signal is given.

As described above, according to the product storage device of the present embodiment, the push-up member 30 for carrying out the product is screwed onto the shaft 20 having a thread extending vertically along the front surface of the product container 10 and is provided with a screw. Since the push-up member 30 is raised and lowered by rotating the shaft 20 with the motor 40, the operating range of the push-up member 30 is set in the front and rear of the product container 10 as compared with the conventional chain rotation type. The product container 10 can be made smaller in that direction.
The capacity of can be expanded.

[0016]

As described above, according to the product storage device of the present invention, the operating range of the product pushing member can be made smaller in the front-back direction of the product container, so that the capacity of the product container is increased accordingly. The product storage efficiency is significantly improved.
