SOLUTION: Inside a commodity storage part 21, commodity T is stored while being piled up in two front and rear lines and ejected forwards successively from the lower most position commodity T. The move for the stroke to move an ejecting member 51 from a rear standby position near the rear end of storage part 21 to an intermediate standby position near the intermediate part of storage part 21 and the move for the stroke to move the ejecting member 51 from that intermediate standby position through a forward ejection completing position near the front end of storage part 21 to the rear standby position are alternately applied to that ejecting member 51. A means 57 to be detected at the intermediate standby position of ejecting member 51 by a rear commodity line detecting means 63 is connected to the ejecting member 51. When both commodity detecting means 62 and 63 detect the absence of commodity, the ejecting operation is inhibited. When the detecting states of both the commodity detecting means 62 and 63 are different, the ejecting member 51 is moved for one stroke. When both the detecting means 62 and 63 detect the presence of commodity, the next ejecting operation is allowed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product dispensing device that stacks and stores products in front and rear two rows in a product storage unit, and sequentially ejects the lowest products forward.

[0002]

2. Description of the Related Art As a conventional product dispensing device, for example,
As described in JP-A-5-189653, a structure adopted in a cigarette vending machine is known.

[0003] In such a device, the product is moved back and forth.
The product throw-out section is arranged below the product storage section to be accumulated and stored in a row, and an endless chain is stretched in the product throw-out section along the front-rear direction and thrown at two symmetrical positions of this chain. A projecting member is provided.

Then, one of the ejection members located at the rear standby position behind the product storage unit moves to the intermediate standby position near the middle of the product storage unit, so that the lowest product in the front row is passed through the lowest product in the rear row. Push the product in the forward direction and throw out this product. Further, the ejection member located at the intermediate standby position moves to the front ejection completion position in front of the commodity storage unit, thereby pushing the lowest product in the front row forward and ejecting it.
Thereafter, the dispensing member that has dispensed the product wraps around the lower region of the chain, and the other dispensing member moves to the rear standby position to prepare for the next dispensing.

Further, optical and lever type sold-out detection means for detecting the presence or absence of a product are arranged near the bottoms of the front row and the rear row of the product storage section, respectively, and the sold-out detection of either the front row or the rear row is detected. When the means detects that the product is out of stock, it judges that the product is sold out and prohibits the product from being put out from the product output device (for example, when the product is sold out, or the product is put out from another product storage device that stores the same product). Switch).

[0006]

However, in the conventional product dispensing device, even if some products remain in the front row of the product storage unit, if there are no products in the rear row of the product storage unit, the product will be dispensed. Prohibition from going out. That is, there occurs a state in which a product remains in the product storage unit but cannot be dispensed.

In order to prevent this, there is a method of instructing the stacking state of the products, for example, by loading one more product in the front row than in the back row when replenishing the products, but it is troublesome for a staff member (a clerk at a cigarette shop, etc.). , Not always protected. Also, the stacking height changes depending on whether the standby position of the ejection member is the rear standby position or the intermediate standby position, and it is difficult to stack one more stack in the front row than in the rear row.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a product dispensing device that can dispense all products in a product storage unit without being restricted when replenishing products. .

[0009]

The product dispensing device of the present invention is a product dispensing device that stacks and stores products in front and rear two rows in a product storage portion and sequentially ejects the lowest products forward.

When any of the detection means detects the presence of a product, the detection means is provided with control means for permitting the next dispensing operation.

Then, when there are sufficient products in the product storage unit and the ejection member is in the rear standby position, when the ejection member moves from the rear standby position to the intermediate position, the front row through the lowest product in the rear row. The lowest products are pushed out and thrown out. When the dispensing member is in the intermediate standby position, when the dispensing member moves from the intermediate position to the front dispensing completion position, the lowest product in the front row is pushed out and dispensed, and the dispensing member moves to the rear standby position.

Further, when there are no more products in the front row of the product storage unit and the ejection member is in the rear standby position, the front row product detection means detects the presence of the product and the rear row product detection means detects the absence of the product. To do. Therefore, the ejection member is moved by one stroke, and the ejection member moves to the intermediate standby position and stands by. Then, based on the dispensing command, the dispensing member moves from the intermediate standby position to the front dispensing completion position and the lowest product in the front row is dispensed, and the dispensing member reaches the rear standby position.

When the dispensing member is at the intermediate standby position, the front row product detecting means detects the presence of the product by the product, and the rear row product detecting means detects the presence of the product by the detected means of the dispensing member. Therefore, it stands by as it is, and based on the next ejection command, the ejection member moves from the intermediate standby position to the front ejection completion position, the lowest product in the front row is ejected, and the ejection member reaches the rear standby position. .

Further, when there is no product in the rear row of the product storage unit and the ejection member is in the rear standby position, the rear-row product detection means detects that there is a product, and the front-row product detection means does not have the product. To detect. Therefore, the ejection member is moved by one stroke, and the ejection member moves to the intermediate standby position and waits while pushing out the lowest product in the rear row. Then, based on the dispensing command, the dispensing member moves from the intermediate standby position to the front dispensing completion position, the lowest product in the front row is dispensed, and the dispensing member reaches the rear standby position.

When the ejecting member is in the intermediate standby position (which normally cannot occur, even if it occurs due to a bounce during replenishment work, etc.), the front row product detection means detects that there is a product and the rear row product is detected. The means detects the presence of the product by the detected means of the ejection member. Therefore, just wait,
Based on the next ejection command, the ejection member moves from the intermediate standby position to the front ejection completion position, the lowest product in the front row is ejected, and the ejection member reaches the rear standby position.

Further, when there is no product in either the front row or the rear row of the product storage section and the ejection member is at the rear standby position, both the front row product detection means and the back row product detection means detect the absence of the product, The dispensing operation is prohibited (sold out).

When the dispensing member is at the intermediate standby position, the rear row product detecting means detects the presence of the product by the detected means of the dispensing member, and the front row product detecting means detects the absence of the product. Therefore, the ejection member is moved by one stroke, and the ejection member moves to the rear standby position. As a result, both the front row product detection means and the rear row product detection means detect the absence of a product, and the dispensing operation is prohibited (sold out state).

The detection lever 62a of the front row product detection sensor 62 projects to a position corresponding to the front row product T of the product storage unit 21, and the detection lever 63a of the rear row product detection sensor 63 projects to a position corresponding to the rear row product T of the product storage unit 21. It Each of the product detection sensors 62 and 63 is turned on when the detection levers 62a and 63a are pressed downward to detect the presence of a product, and is turned off when the detection levers 62a and 63a are released to detect the absence of a product. To do.

Further, FIG. 5 shows a control means 71, which inputs the dispensing command signal from the vending machine, the position detection sensor 61 and the detection signals from the commodity detection sensors 62, 63. , Control the drive motor 44.

That is, the ejection member 51 is moved from the rear standby position near the rear end of the product storage section 21 to the intermediate standby position near the middle of the product storage section 21, and the product storage is started from the intermediate standby position. The second movement of moving to the rear standby position through the front ejection completion position near the front end of the portion 21 is controlled so as to be alternately given.

Further, when the ejection member 51 reaches the rear standby position or the intermediate standby position, the control means 71 compares the detection states of the commodity detection sensors 62 and 63, and ejects them on condition that the detection results are different. The member 51 is moved by one stroke (from the standby position to the next standby position). Further, when the detection states of both the product detection sensors 62 and 63 are off (no product), product ejection is prohibited (“Sold out” is displayed, or another product that stores the same product T is placed. Switch to eject the product T from the exit position.). Further, when the detection states of both the product detection means 62 and 63 are ON (there is a product), the next dispensing operation is permitted.

Next, the operation of the present embodiment will be described.

In the product storage unit 21, products T are stacked and stored in front and rear two rows. At this time, the product T in the front row has the front upper surface 32a.
The product T in the rear row is placed on the rear upper surface 32b, and the product T in the front row is placed at a position slightly higher than the product T in the rear row.

Then, first, the case where there are enough products T in the product storage unit 21 will be described.

The first standby state is when the ejection member 51 is at the rear standby position behind the product storage section 21. In the first standby state, the engagement pin 45 of the drive belt 42 is located near the rear end of the rear pulley 41, and the first detection protrusion 59 is detected by the position detection sensor 61. At this time, as shown in FIG. 6A, the detection levers of the front row and rear row product detection sensors 62, 63
Since 62a and 63a are still held by the product T, the front row and rear row product detection sensors 62 and 63 are both in the same ON state (there is a product), and wait for the ejection command.

When the ejection is instructed, the drive motor 44 is driven and the drive belt 42 is rotated in the counterclockwise direction in FIG. The ejecting member 51 moves forward in accordance with the movement of the engagement pin 45, enters the product storage unit 21 through the passage hole 25 in the lower portion of the rear plate 24, and the rear row lowest product T and the front row lowest product T are separated. Push. The ejection member 51 pushes the lowest product T in the rear row to the front row, and the lowest product T in the front row is ejected forward through the ejection port 23.

At this time, the stepped portion 33 is formed on the bottom surface of the product storage portion 21.
Is formed, and the product T in the front row is higher than the product T in the back row, the front row upper end of the back row lowest order product T does not get caught on the back side lower end of the front row next order product T and only the front row lowest order product T is formed. Can be pushed out.

The rear-row next-order product T, which falls when the rear-row lowest-order product T moves forward, is placed on the support member 54 which has entered the product storage section 21 in a continuous manner with the ejection member 51. Since the second-order product T falls on the support member 54, the difference is smaller than the thickness of the product T, and the degree of inclination of the second-order product T is suppressed, so that clogging is less likely to occur. Further, even when the remaining amount of the product T becomes small, the shock of dropping the product T is suppressed, and it is difficult to cause the stacking failure.

Then, when the drive belt 42 is rotated about a quarter turn and the second detection protrusion 60 is detected by the position detection sensor 61, the drive motor 44 is stopped and the second standby state is set.
At this time, the ejection member 51 is located at the intermediate standby position near the middle of the product storage unit 21. The rear row product detection sensor 63 is turned on by pressing the detection lever 63a by the support member 54. On the other hand, the detection lever 62a of the front row product detection sensor 62
Remains pressed by the product T, the front-row and rear-row product detection sensors 62 and 63 are both in the same ON state (there is a product), and wait for the next dispensing command.

When the next ejection is instructed, the drive motor 44 is driven again. When the engagement pin 45 moves forward, the ejection member 51 moves forward, and the lowest product T in the front row is ejected through the ejection port 23. When the engagement pin 45 reaches the vicinity of the front edge of the front pulley 40, the front surface of the ejection member 51 reaches the vicinity of the front end of the product storage unit 21.

The front-row next-order product T, which falls when the lowest product T in the front row is thrown out, is placed on the support member 54 which has entered the product storage section 21 in a continuous manner with the dispensing member 51.
Since the next-order product T falls on the support member 54, the drop is smaller than the thickness of the product T, and the accumulation failure is less likely to occur.

The drive belt 42 is further rotated and the engagement pin
When 45 reaches the vicinity of the rear edge of the rear pulley 41 and the first detection protrusion 59 is detected by the position detection sensor 61, the drive motor 44 is stopped and the state returns to the first standby state. The ejection member 51 is also retracted to the rear standby position behind the product storage unit 21, and the support member 54 is hung downward from the rear. The front row product T placed on the support member 54 is on the front side upper surface 32a, and the rear row product T is on the rear side upper surface 32b.
Placed on top of each.

At this time, sufficient product T is stored in the product storage unit 21.
If there is, the detection levers 62a and 63a of the front-row and rear-row product detection sensors 62 and 63 are still held by the product T, so both the front-row and back-row product detection sensors 62 and 63 are turned on (there is a product). Yes, it waits for the next dispatch command as it is.

It should be noted that the ejection of the product T from the first standby state and the ejection of the product T from the second standby state are cyclically performed, and it does not matter which standby state comes first. Absent.

Next, a case where the remaining amount of the product T in the product storage unit 21 is reduced and only the product T in the front row is lost will be described.

As shown in FIG. 6 (d), when the ejection member 51 is at the rear standby position and the product T in the front row is exhausted, the front row product detection sensor 62 is turned off when the detection lever 62a is released. None) state. On the other hand, even when the ejection member 51 is at the rear standby position, the rear row product detection sensor 63 has the detection lever 63a pressed by the product T remaining in the rear row.
The rear row product detection sensor 63 is turned on (there is a product).

At this time, the detection result of the front row product detection sensor 62 (OFF) and the detection result of the rear row product detection sensor 63 (ON)
, The drive motor 44 is driven, and the ejection member 51 is moved by one stroke (to the intermediate standby position). As a result of this movement, as shown in FIG. 6B, the rear row product T is moved to the front row, and this product T presses the detection lever 62a of the front row product detection sensor 62, so that the front row product detection sensor 62 is turned on ( There is a product) state. On the other hand, since the detection lever 63a of the rear row product detection sensor 63 is pressed by the support member 54, the rear row product detection sensor 63 is turned on (there is a product). As a result, the front-row and rear-row product detection sensors 62 and 63 are both in the same ON state (there is a product), and wait for the next ejection command. If there is a dispensing command, the drive motor 44 is driven and the dispensing member 51 reaches the rear standby position after dispensing the lowest product T in the front row.

Further, as shown in FIG. 6 (e), the ejection member 51
Is in the intermediate standby position, the detection lever 63a of the rear row product detection sensor 63 is pressed by the support member 54, so that the rear row product detection sensor 63 is turned on (there is a product). on the other hand,
The front row product detection sensor 62 is turned off (no product).
Therefore, since the detection result of the front row product detection sensor 62 (OFF) and the detection result of the rear row product detection sensor 63 (ON) are different, the drive motor 44 is driven, and the ejection member 51 corresponds to one stroke (it reaches the frontmost position). After that, it is moved to the rear standby position) and normally becomes as shown in FIG. 6 (f). When the product T is placed on the support member 54, the product T is dropped on the rear upper surface 32b due to the withdrawal member 51 retracting, and the product T shown in FIG.
The state shown in (d) is reached.

Next, a case where the remaining amount of the product T in the product storage unit 21 is reduced and only the product T in the rear row is lost will be described.

As shown in FIG. 6C, when the ejection member 51 is at the rear standby position and the product T in the rear row runs out, the detection lever 63a of the rear row product detection sensor 63 is released to detect the rear row product. The sensor 63 is turned off (no product). On the other hand, in the front row product detection sensor 62, the detection lever 62a is pressed by the product T and is in the ON state (the product is present). That is, since the detection result (ON) of the front row product detection sensor 62 and the detection result (OFF) of the rear row product detection sensor 63 are different, the drive motor 44 is driven, and the ejection member 51 corresponds to one stroke (to the intermediate standby position). Can be moved. By this movement, the rear row product detection sensor 63 is pressed by the support member 54, and the rear row product detection sensor 63 is turned on (there is a product) (state of FIG. 6B). As a result, the front-row and rear-row product detection sensors 62 and 63 are both in the same ON state (there is a product), and wait for the next ejection command. If there is an ejection command, the drive motor 44 is driven and the ejection member 51
After throwing the lowest product T in the front row, it returns to the rear standby position, and normally becomes as shown in FIG. 6 (f). When the product T is placed on the supporting member 54, the product T is dropped on the rear upper surface 32b as the ejecting member 51 retracts, and the product T shown in FIG.
The state shown in FIG.

Next, the case where the product T is completely absent in the product storage section 21 will be described.

As shown in FIG. 6 (f), when the ejection member 51 is at the rear standby position and no commodities T are left in the commodity storage portion 21, the front row and rear row commodity detection sensors 62, 63 are detected.
Since both detection levers 62a and 63a are released, both product detection sensors 62 and 63 are turned off (no products),
The ejection of the product T from the product ejection device is prohibited.

As shown in FIG. 6 (e), when there is no product T in the product storage unit 21 with the ejection member 21 in the intermediate standby position, the detection lever 62 of the front-row product detection sensor 62 is detected.
a is released, and the front row product detection sensor 62 is turned off (no product). On the other hand, the detection lever 63a of the rear row product detection sensor 63 is pressed by the ejection member 51, and the rear row product detection sensor 63 is turned on (there is a product).

At this time, the detection result of the front row product detection sensor 62 (OFF) and the detection result of the rear row product detection sensor 63 (ON)
Therefore, the ejection member 51 is moved by one stroke (returns to the rear standby position after reaching the frontmost position). Discharging member
When 51 reaches the rear standby position, as shown in Fig. 6 (f),
Both the product detection sensors 62 and 63 are turned off (no product), and the product T is prohibited from being ejected from the product ejection device.

It should be noted that a state in which all the products T are completely lost in the product storage portion 21 when the ejection member 51 is in the intermediate standby position cannot normally occur. Although the dispensing of the product T from the dispensing device is prohibited, no further inconvenience is caused to the user.

Then, each product detection sensor as described above
Table 1 below summarizes the relationships between the detection results of 62 and 63, the condition inside the product storage unit 21, the standby position of the ejection member, and the next operation.
