Description

[Detailed explanation of the idea] The present invention relates to the structure of an article storing and discharging device.

For example, in Japanese Patent Publication No. 46-41925, as an article storing and discharging device suitable for handling articles with a circular cross section, packets each having a semicircular cross section are made to correspond to the lower ends of a plurality of inclined article shelves, and a sales signal is transmitted. It is disclosed that the articles on each article shelf are sequentially discharged from the lower shelf by interlockingly rotating the packets as they are received.

However, in the device disclosed in the publication, if there are no items on the bottom shelf, the items on the shelves above it are discharged, so when the items are refilled on the bottom shelf, the items are not refilled. The old items will be discharged before the items on the upper shelf, and the old items will remain on the upper shelf.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a first-in, first-out system for an article storing and discharging device for a vending machine that uses a plurality of inclined article shelves to automatically discharge articles.

Examples will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration of an embodiment of an article storage and discharge device according to the present invention.

This article storing and discharging device has three upper and lower article storing sections 1a,
1b, lc.

Each article storage section has upper and lower shelves 2 and 3 that are inclined in the same direction.

A large number of articles A are placed on these shelves 2 and 3 in a diagonal direction.

Furthermore, rotatable packets 4 and 5 are provided at the lower end of the space above each state 2 and 3, respectively, to face each other.

A guide plate 6 is provided below the lower packet 4 of the pair of packets 4 and 5 arranged above and below.

Here, the lowermost guide plate 6 is made integrally with the article holder 7, but of course it can be made separately.

On the other hand, a guide plate 8 is also provided in front of the upper packet 5.

Further, in front of the lower packet 4, a shutter 9 for opening and closing the article discharge port is provided.

All packets 4 and 5 are, for example, as shown in FIG.
All are connected to rotate in conjunction with each other by a suitable interlocking mechanism 11 such as a chain and a sprocket, a timing belt and a gear, or mutual meshing of gears, and are driven by a single reversible motor M.

As a result, packets 4 and 5 all rotate in conjunction.

At this time, the paired packets 4 and 5 are shifted in phase from each other in advance.

This phase shift angle is selected within the range of 180°±30°.

Further, the stopping positions of the packets 4 and 5 are set at positions that prevent the articles A from rolling and falling from the shelves 2 and 3.

Note that the rotation angles of the packets 4 and 5 can be detected by a cam switch SW corresponding to a cam 12 rotationally driven by a motor M, as shown in FIG. 3, for example.

Each of the shutters 9 can be driven separately by a rotary solenoid SL, one of which is illustrated in FIG.

That is, when the rotary solenoid SL is energized, the drive shaft 13 of the shutter 9 is rotated about 90 degrees, and when the energization is cut off, it is returned by the restoring force of the return spring 14.

Note that the shutter 9 may be driven up and down.

By the way, only the pair of packets 4 and 5 will be taken up, and their driving state will be explained assuming that the shutter 9 is open.

First, when the packets 4 and 5 are driven clockwise as shown in FIG. 5, the articles on the upper shelf 3 are discharged, as can be seen in the order shown in FIGS.

On the other hand, when the packets 4 and 5 are driven counterclockwise as shown in FIG. 6, the articles on the lower shelf 2 are discharged, as can be seen in the order of FIG. 6 a to e.

Therefore, if we focus only on the pair of packets 4 and 5,
If the packets 4 and 5 are reversed every rotation, the articles A will be alternately discharged from the upper and lower shelves 2 and 3.

Note that when one shelf 2 or 3 is empty, articles are discharged only from the other shelf.

Now, Fig. 7 shows the motor M and solenoid SLa.

The specific energization control circuit of SLb and SLc is connected to terminal T1.
゜T2 is shown connected to the power source and the sold-out detection relay SO is energized.

In addition, sold-out detection relay 5o (7) contacts SOa, Sob
, SOc, Sales IJL/-V(7) Contact v1. v2.
v3, L/-RE, contact re, and relay RE
It is assumed that both contacts re2 of 2 are connected to the black circle contact side when the relay is not energized, and are switched to be connected to the white circle contact side when the relay is energized.

S is a rotary stepping relay, which advances its contact S every time the current is cut off, and solenoid SLa
, SLb, and SLc in turn.

These solenoids SLa, SLb, and SLc are for driving shutters 9 that correspond one-to-one to each article storage section 1a, lb, and lc.

Further, R is a keep relay, which switches and connects the contact r between the forward rotation terminal Mf and the reverse rotation terminal of the reversible motor M every time the current is cut off.

Now, when a predetermined amount of coins are inserted and a sales signal is supplied to terminal Ta from a coin mechanism (not shown), sales relay V is energized.

The energized state of this sales relay V is determined by its contacts v1 and v2.
It is self-maintained by etc.

The contact v3 is closed by the energization of the sales relay V, and the reversible motor M starts rotating forward, for example.

Then, the cam switch SW is switched to the white circle contact side, and the solenoid SLa is energized to close the lowermost article storage section 1.
The shutter 9 corresponding to a is opened.

As a result, one article A is discharged from the upper shelf 3 of the lowermost article storage section 1a according to the rotation of the packets 4 and 5, for example, clockwise.

When the packets 4 and 5 rotate once, the cam switch SW switches to the black circle contact side, and the stepping relay S is de-energized, so the contact S steps forward and the next solenoid SLb
connected to.

Also, at this time, since relay RE1 operates with a delay, both contacts re□ and re2 are temporarily opened,
As a result, the self-holding of the sales relay (2) is released, and its contact v3 opens, thereby stopping the motor M.

When the next sales signal is supplied to the terminal Ta, the same operation as described above is performed except that the solenoid SLb is energized, and one article A is discharged from the upper shelf 3 of the middle article storage section 1b.

There is no need to explain that the solenoid SLC is then energized and one article A is discharged from the uppermost article storage section 1c.

However, at this time, the keep relay R is energized and at the same time the cam switch SW is switched to the black circle contact side, the energization of the keep relay R is cut off. Ru.

When the next sales signal is further supplied to the terminal Ta, the motor M reverses and rotates the packets 4 and 5 counterclockwise.
At the same time, the solenoid SLa is energized and the shutter 9 corresponding to the lowermost article storage section 1a opens.

As a result, one article A is discharged from the lower shelf 2 of the lowermost article storage section 1a.

Thereafter, by repeating the same operation, the articles A are discharged one by one while switching between the shelves 2 and 3.

In this way, articles are placed on the plurality of shelves 2 and 3 on a first-in, first-out basis, so there are no old articles left behind, making it suitable for use in a vending machine.

In addition, although the above description has been made regarding the case where the article storage section has three stages, the present invention can be implemented even if the number of stages is different as long as the article storage section has multiple stages, and the same effect can be obtained.
