Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine.

[0002]

2. Description of the Related Art Heretofore, there has been proposed an automatic vending machine which stacks products in front and rear rows in one column and successively carries out the bottom products from each row.

For example, as shown in FIG. 10, a bottom plate 102
Column 10 for stacking and storing products T in front and rear two rows
Below 1 is a pair of chain wheels 103, 104,
There has been proposed an automatic vending machine 100 having a carry-out mechanism including a chain 105 suspended between the chains 105 and a pair of push-out members 106 attached to the chain 105.

In the vending machine 100, the chain wheel 103 rotates in the selling state to move the column 101.
The pushing member 106 located at the rear of the bottom plate 102
It is guided to the long hole 107 provided in the column and travels in the column 101. Then, the rear surface of the lowermost product T1 in the rear row is pushed out to the vicinity of the center of the column 101, and the lowermost product T0 in the front row is dropped to the front product outlet 108. After that, the push-out member 106 is stopped and put in a standby state for sale (state of FIG. 10). When the next sale state is reached, the pushing member 106 pushes the product T1 forward of the column 101 and drops it into the product outlet 108. As a result, the products T at the bottom of each row are carried out one by one in the order of the front row and the rear row.

[0005]

In such a vending machine 100, when the push-out member 106 stands by behind the lowermost product in the rear row (the push-out member 106 is in the position shown in FIG. 11). When the same number of products T are placed in the front and rear rows, the last product T can be sold out.
However, at this time, if the number of the products T in the front and rear rows is different, the last product T cannot be sold out.

This will be described with reference to FIG. In the sales standby state of FIG. 11, one product T11 remains in the front row, two products T12 at the bottom and the second product T13 from the bottom remain in the rear row, and the pushing member 106 is the column 101.
Waiting behind. When the state is changed to the sale state, the pushing member 106 advances forward in the column 101,
The product T11 in the front row is dropped to the product outlet 108 in the front. At that time, the product T1 in the rear row is pushed by the pushing member 106.
2 and T13 move to the front row. In the next sale state, the pushing member 106 pushes the product T12 in front of the product T12 forward, drops the product T12 in the product outlet 108, and exits in front of the column 101. Then, when the sales standby state of FIG. 11 is resumed, only one product T13 is provided in the front row in the column 101.
Will remain. From this state to the sale state,
The pushing member 106 moves only to the center of the column 101, and the product T11 does not drop into the product carry-out port 108.
Therefore, there is a problem that the product T is not delivered even though the product T remains.

Therefore, in order to sell out the last product T, when the product T is stored in the column 101, the same number of products T are stored in the front and rear rows while the push-out member 106 stands by behind the column 101. I have to let you. However, since it is practically impossible to force this person to operate the vending machine, conventionally, the product T in the second stage or the third stage from the bottom of the column 101 comes into contact. The above-mentioned problem is solved by providing a sold-out switch at such a position that the product T is sold out with one or two stages left so that the product T is not sold further. It was

However, when the product T is left in the sold-out state as described above, there is a problem that the product storage capacity is reduced and the sales efficiency is reduced. Further, there is a problem that products such as food and drink whose quality deteriorates with time cannot fully meet the demand of the seller who wants to provide more fresh products to customers.

In view of the above points, the present invention provides an automatic vending machine for storing products in a plurality of rows in the front and rear, which can sell out the last product without leaving it.

[0010]

The vending machine according to claim 1 of the present invention stores a plurality of products in a plurality of rows in front and rear in one column, and stores the articles in a front-back direction provided below the column. An extruding member for extruding the lowermost product forward is attached to an endless member composed of a movable chain, belt, etc., and the extruding member stops between the lowest products in each row, and then stops By pushing the pushing member to the next stop position, the product in front of the pushing member is pushed forward and only the lowermost product in the front row is dropped to the product carry-out port provided in front of the column, In an automatic vending machine that sequentially drops the products at the bottom of each row to the product outlet, the discharge member that detects the products falling from the column is provided at the product outlet, and the pushing member that has stopped is Next stop position In when it moves, the when the discharge detection means does not detect the product until said discharge detecting means detects the item, and moves the pusher member further to the next stop position.

According to the vending machine of claim 2 of the present invention,
The vending machine according to claim 1, further comprising a sold-out detection means for detecting the sold-out of the product placed at the bottom of the column, and when the sold-out detection means detects the sold-out,
The pushing member does not move.

[0012]

In the automatic vending machine according to the first aspect of the present invention, when the push-out member which is in the sale state and stopped and moves to the next stop position, and the carry-out detecting means does not detect the product, the carry-out detecting means. Since the pushing member is further moved to the next stop position until the product detects the product, all the products stored in the column can be carried out.

Further, in the automatic vending machine according to claim 2 of the present invention, when the products placed at the bottom of the column are exhausted, the sold-out detection means detects the sold-out of the column, and then the sales command is issued. The pushing member does not move even if a signal is input.

If the FF state remains, the process returns to step 3.

The operating state of the vending machine 10 will be described below. When steps 1 to 6 are described there, the control stage of the microcomputer 50 is shown.

First, the normal operating state of the vending machine 10 will be described with reference to FIGS. For convenience of explanation, the state shown in FIG. 1 is used as a starting point, and in this state, the cigarettes T stored in the front row of the column 12 are sequentially stored from the bottom as TF1, TF2, TF3 ... Tobacco T in order from the bottom, TR1, TR2, TR3
... Of course, both (TF and TR) are cigarettes of the same brand.

(1) First sales standby state (state of FIG. 1) One extruding member 30 is located at the rear of the column 12, and its protrusion 34 contacts the rear limit switch 38 to cause the motor 48 to move. Is stopped. The other pushing member 30 is located in front of the column 12. The sold-out switch 40 is turned off by the cigarette TF1 in the front row.

(2) First sale state In the first sale standby state, when the sale command signal is input, the sold-out switch 40 is in the OFF state.
The motor is driven so that the front chain wheel 20 moves to the position shown in FIG.
At, the chain 28 rotates counterclockwise and travels (steps 1 to 3). As a result, the pushing member 30 located at the rear enters the column 12 from the rear of the column 12 and travels in the column 12 while pushing the rear surface of the lowermost tobacco TR1 in the rear row forward. At this time, the bottommost tobacco TR1 in the rear row is replaced with the bottommost tobacco T in the front row.
Since F1 is pushed forward, these two cigarettes TR1,
The TF1 as a whole begins to slide forward on the bottom plate 16.

Extruding member 3 extruding tobacco TF1
When 0 runs near the center of the bottom plate 16, the following two things occur almost simultaneously.

A) The cigarette TF1 at the bottom of the front row falls through the front gap 12d to the commodity outlet 14. At this time, the cigarette TF1 pushes down the pin 46 of the carry-out detection switch 44 to the ON state, and then returns to the OFF state (see FIG. 2).

B) The front limit switch 36 is turned on by the protruding portion 34 of the chain 28 traveling on the lower traveling path, and the motor is stopped (steps 4 and 5).

Therefore, from step 6, the control of the carry-out operation of the microcomputer 50 is finished, the first sale state is finished, and the second sale standby state is entered.

(3) Second sales standby state (state of FIG. 2) Tobacco TR1 in the lowermost row of the rear row in the first sales standby state
Are located at the bottom of the front row. Further, the cigarette TR2 placed on the second row from the bottom in the rear row falls on the bottom plate 16 and is located at the bottom row. These two cigarettes TR
The push-out member 30 is located between 1 and TR2.

(4) Second sale state In the second sale standby state, when the sale command signal is input, the sold-out switch 40 is in the OFF state.
The motor 48 is driven and the chain 28 travels (steps 1 to 3). The pushing member 30 located in the column 12 pushes the cigarette TR1 at the lowermost stage in the front row forward and drops it into the commodity outlet 14 in front of the column 12. At this time, the cigarette TR1 pushes down the pin 46 of the carry-out detection switch 44 to the ON state, and then the
Return to FF state.

When the push-out member 30 moves forward from the column 12, the protruding portion 34 of the other push-out member 30 comes into contact with the rear limit switch 38 to be turned on and the motor stops (step 4, 5).

From step 6, the control of the carry-out operation of the microcomputer 50 is finished, the second sale state is finished, and the first sale standby state is entered (state of FIG. 1).

As described above, the automatic vending machine 10 carries out the cigarettes T, which are stacked in the front and rear two rows on the column 12, one by one from the cigarettes T at the bottom. That is, FIG.
In this state, the unloading order is TF1, TR1, TF
2, TR2, ... When a large number of cigarettes T are stored in the column 12, one cigarette T can be carried out by one carrying-out operation including steps 3 to 5.

Next, the situation when the vending machine 10 is sold out will be described. Unless otherwise indicated, the products are unloaded by the above-described unloading operation in each sales state.

(A) When the same number of cigarettes T are placed in the front and rear rows in the first sales standby state (assuming that two cigarettes T are placed in each of the front and rear rows as shown in FIG. 7A) .

In the first sale state, the cigarette TF1 in the lowermost row in the front row is carried out to enter the second sale standby state.
As shown in (b), the number of cigarettes in each row is two (T
R1 and TF2), and one in the rear row (TR2).

In the second sale state, the cigarette TR1 is unloaded and enters the first sale standby state. As shown in FIG. 7C, one cigarette is provided in each of the front and rear rows (TF2, T).
R2).

In the first sale state, the cigarette TF2 in the front row
Are carried out to enter the second sale standby state, and as shown in FIG. 7 (d), the number is one in the front row (TR2).

In the second sale state, the cigarette TR2 is unloaded, the cigarette T disappears from the column 12, the sold-out switch 40 is turned on, and the sold-out lamp is turned on.

As described above, when the same number of cigarettes T are placed before and after the first sales standby state, the number of cigarettes is always 1
One cigarette is carried out by one carrying-out operation, and all the cigarettes T are sold out.

(B) When the number of cigarettes T placed in the front row in the first sales standby state is larger than that of cigarettes T placed in the rear row (as shown in FIG. 8A), 2 cigarettes TF1 and TF2, 1 cigarette T in the back row
R1 is mounted).

In the first sale state, the cigarettes TF1 in the front row are carried out to enter the second sale standby state, and as shown in FIG. 8B, there are two cigarettes (TR1, TF2) in the front row.

In the second sale state, the cigarette TR1 is unloaded, enters the first sale standby state, and becomes one (TF2) in the front row as shown in FIG. 8C.

When the sales command signal is input to the microcomputer 50 from the state of, the sold-out switch 40 is turned on by the cigarette TF2 in the front row, so the motor 48 is driven to enter the first sale state (step 1-3). When the push-out member 30 at the rear of the column 12 moves to the central portion of the column 12 (the push-out member 30 shown by the dotted line in FIG. 8C), the lower protrusion 34 comes into contact with the front limit switch 36, and 48 stops (step 4,
5).

In, one cigarette (T
Since only F2) remains, it is not carried out, and the carry-out detection switch 44 has never been in the ON state since the sales command signal was input. Therefore, the microcomputer 50 returns from step 6 to step 3,
Further, the motor 48 is driven. That is, the second sale state is entered, and the pushing member 30 causes the cigarette TF2 in the front row to drop to the front commodity outlet 14. As a result, the sold-out switch 40 is turned on, and the sold-out lamp lights up.

In this way, in the first sales standby state,
When there are more cigarettes T in the front row, the cigarettes T are removed from the rear row first, and the cigarettes T are placed only in the front row. In this case, the cigarette T cannot be unloaded in the first sale state, and the cigarette T can be sold out to the end by performing the unloading operation in the second sale state.

(C) When the number of cigarettes T placed in the rear row is larger than the number of cigarettes T placed in the front row in the first sale standby state (as shown in FIG. 9A) One cigarette TF1 in the back and two cigarettes TR1, T in the back row
R2 is mounted).

In the first selling state, the pushing member 30 pushes out the lowermost tobacco TR1 in the rear row, and the tobacco T in the front row.
F1 is carried out and enters the second sales standby state. At this time,
The tobacco TR2 in the second row from the bottom in the rear row moves to the front row together with the tobacco TR1 therebelow, and the number of cigarettes in the front row becomes two (TR1, TR2) as shown in FIG. 9B.

Hereinafter, as in the case where the number of cigarettes T in the front row (B) is larger (to), the first sales standby state (one in the front row (TR2)) in FIG. In response to the sales command signal, the carrying-out operation is performed twice (first sales state and second sales state) via the microcomputer 50, and the cigarette TR
Carry out 2. Then, the sold-out switch 40 is turned on, and the sold-out lamp lights up.

As described above, even when there are more cigarettes TR in the rear row in the first sales standby state, the cigarettes TF in the front row are
When there is only one 1, in the next first selling state, all the cigarettes TR in the rear row move to the front row together with the cigarettes TR1 in the lowermost row. Therefore, when the cigarette T remains in the column 12 in the sale standby state, the sold-out switch 40 is always in the OFF state.

After that, even if the cigarette T remains in the front row only in the first sale standby state, the carry-out operation is performed until the carry-out detection switch 44 detects the carried-out cigarette T. The cigarette T can be sold out.

In the above (A) and (B), the case where the number of cigarettes T in the front and rear rows is different by one has been described, but even when the number of cigarettes T is different by two or more, the cigarettes T should be carried out to the end as well. You can In this case, when the front and rear rows are different by n in the first sale standby state, FIG.
In the first sales standby state shown in (c), since there are n cigarettes T remaining only in the front row, the operation of (B) may be performed n times.

As described above, regardless of the number of cigarettes T placed in the front and rear rows, when the cigarettes T in one row of the column 12 are exhausted due to the sold-out, the cigarettes T are always placed in the front row. Has been done. That is, when the cigarette T remains in the column 12, the sold-out switch 40 is always in the OFF state in the sales standby state. Further, at that time, even in the first sale standby state in which the pushing member 30 is waiting behind the column, the carry-out operation is performed until the carry-out detection switch 44 detects that the cigarette T is carried out. You can sell out all the cigarettes T until the end.

In the automatic vending machine 10 of the present embodiment, the carry-out detection switch 44 of the micro switch type is used to detect the cigarette T falling to the product carry-out port 14, but the present invention is not limited to this. Alternatively, for example, an optical sensor may be attached to both sides of the product outlet 14 and the cigarette T may be detected by this sensor.

Further, in the vending machine 10 of this embodiment, a plate for partitioning the cigarettes T in the front and rear rows is not provided at the center of the column 12, but such a plate may be provided. However, in that case, a sell-out switch for detecting whether or not cigarettes remain is provided for all rows. For example, the sold-out switches 40 of this embodiment are provided in the front and rear rows, or optical sensors or the like are provided in the front and rear of the column 12 to detect whether or not the cigarette T remains in the column 12. When this partition plate is not provided as in the present embodiment, the sell-out switch 40 need only be provided in the front row. Further, without the partition plate, the cigarette T can be stored easily without disturbing the storage of the cigarette T in the column.

Furthermore, in the above embodiment, the vending machine which stores the products in the front and rear two rows is described.
It may be stored in three or more rows in the front and rear, and can be determined in consideration of the size of the product, the allowable depth dimension of the vending machine, and the like. Even when storing products in multiple rows in such a column, if there is no partition plate that partitions the products in each row above, at least one product is always placed in the front row until the products run out. Therefore, it is sufficient to provide the sold-out switch 40 in the front row. Further, especially when the plurality of rows are formed in this way, it is easier to store the products without the partition plate.

In the automatic vending machine of the present invention, the front and rear of the above-described product unloading device are reversed and the automatic vending machine 1 is used.
It may be provided within 0. That is, the product outlet 14 may be provided behind the column 12, and the pushing member 30 may push the front surface of the product T backward so that the product T is dropped behind the column 12.
