Field of the Invention The present invention relates to a merchandise storing and dispensing apparatus for a vending machine for storing a plurality of commodities arranged in the front-rear direction and for dispensing the foremost commodities among a plurality of commodities during sale. .

[0002]

2. Description of the Related Art The present applicant has already proposed a product storage and dispensing device for a vending machine of this type (for example, Japanese Patent Application No. 11-110,197).
251854). This product storage and dispensing device includes a horizontal product rack provided in a vending machine, and a plurality of product dispensing mechanisms mounted on the product rack. For example, a hanging-type product dispensing mechanism that dispenses commodities stored in a suspended state has a spiral protrusion that extends horizontally in the front-rear direction and that extends continuously in a spiral shape on the surface, and a plurality of The product is composed of a product hanging bar on which products are arranged and suspended in the front-rear direction, and three units for rotating and driving the product hanging bar in a predetermined direction. These three units extend in the front-rear direction and transmit power from front to rear,
The rotary shaft conversion unit converts the rotation axis of the transmitted power to output the rotation shaft, and the rotation drive unit that rotates the product hanging rod with the power output from the rotation shaft conversion unit.

A product dispensing mechanism having such three units is configured so as to be movable between each product dispensing mechanism and a product outlet, and a bucket that conveys the dispensed products to the product outlet at the time of sale. It is adapted to be driven by. That is, this bucket has a gear that can move backward and forward and a motor that rotates the gear.
At the time of sale, the gear of the bucket engages with the gear provided at the front end of the power transmission unit, and by rotating this, the product hanging bar rotates.

[0004] In the vending machine having the above-mentioned commodity storing and dispensing apparatus, when a commodity is selected at the time of sale, the bucket moves to the front of a commodity dispensing mechanism having a commodity hanging bar for suspending the selected commodity. Then, the gears of the bucket protrude rearward and are rotationally driven by the motor in a state of meshing with the gears of the power transmission unit. This allows
The power of the motor provided in the bucket is sequentially transmitted to the power transmission unit, the rotation axis changing unit, and the rotation drive unit, and the product hanging bar rotates in a predetermined direction. When the product hanging bar rotates, the sales product located at the forefront of the plurality of products hanging on the bar is detached from the front end of the product hanging bar and stored in the bucket. When this is detected by a sensor provided on the bucket, the motor of the bucket is stopped, thereby stopping the rotation of the product hanging bar. Then, the bucket moves toward the product outlet, and the sold product is carried out to the product outlet.

As shown in FIGS.
Has a play insertion hole 84b into which a rotating shaft 83a of the third gear 83 is loosely inserted, at one end of a metal plate having a predetermined shape, which is appropriately bent. A connecting shaft 86 is provided at the other end of the rotating plate 84 so as to project rightward in parallel with the rotating shaft 83 a of the third gear 83 and to be connected to the chute plate 74. The connecting shaft 86 is loosely inserted into an arc-shaped guide groove 61 a formed in the partition wall main body 61. This guide groove 61a is
As shown in FIG. 3 and FIG.
From a position almost directly below the rotation shaft 83a to a position obliquely forward of the rotation shaft 83a. Therefore, the connecting shaft 86 can move from the lower end to the upper end of the guide groove 61a, and accordingly, the rotation range of the rotation plate 84 is regulated. . A tension spring 84c (see FIGS. 10 and 12) is connected to the other end of the rotating plate 84, so that the rotating plate 84 rotates counterclockwise in FIG. Being energized.

The rotating plate 84 is pressed by the compression spring 87 toward the right end of the rotating shaft 83. Therefore, when the third gear 83 rotates, the rotating plate 84 rotates by the frictional force due to the rotation.

With the switch / chute driving mechanism 54 configured as described above, ON / OFF switching of the switch 52 and driving of the chute 53 are performed as follows. That is, as shown in FIG. 5, during standby for sale, as shown in FIG. 5A, the rotating plate 84 is urged by the tension spring 84c to rotate counterclockwise. Therefore, the connecting shaft 86 is in contact with the lower end of the guide groove 61 a of the partition wall main body 61. Thereby, the rotating plate 84 is held in an upright posture (hereinafter, referred to as “upright posture”) such that the bending portion 84 is located on the upper side and the connecting shaft 86 is located on the lower side. In this case, when the bending portion 84 a presses the operating portion 52 c of the switch 52, the turning plate 84 turns the switch 52 to the OFF state and the chute main body 72.
5A, and is held at the standby position shown in FIG.

On the other hand, at the time of sale, the first gear 81 is driven by a driving gear 123 (see FIGS.
), The third gear 83 is also rotated clockwise via the second gear 82. Then, due to the frictional force generated by the rotation of the third gear 83, the rotating plate 84 causes the tension spring 84
It rotates clockwise against c. Then, the connecting shaft 86 comes into contact with the upper end of the guide groove 61a, and the rotating plate 84 assumes a substantially horizontal posture (hereinafter, referred to as "horizontal posture") as shown in FIG. 5B. In this case, the bent portion 84a of the rotating plate 84 is separated from the operation portion 52c of the switch 52, thereby turning on the switch 52. In addition, as the connecting shaft 86 moves to the upper end of the guide groove 61a, the chute plate 74 is tilted forward and downward from the horizontal position (FIG. 5A) (FIG. 5 (A)). b) position),
Accordingly, the slide plate 73 is moved to the standby position (FIG. 5).
From the position (a)), it moves to the delivery position (the position in FIG. 5B) slightly ahead of this, specifically, slightly ahead of the front end of the product path. When the rotation of the third gear 83 stops, the rotating plate 84 in the horizontal posture returns to the original standing posture shown in FIG. 5A by the tension spring 84c. Accordingly, the chute plate 74 and the slide plate 73 return to the horizontal position and the standby position, respectively.

FIG. 7 shows two chute adapters 91 and 91 which can be attached to the chute plate 74 and an attitude control member 55 which is attached to the partition wall main body 61 in order to control the attitude of the product S for sale. The state is shown.
The chute adapter 91 is formed in a rectangular shape in plan view, has substantially the same dimension in the front-rear direction as that of the chute plate 74, and has a longer dimension in the left-right direction than that of the chute plate 74. It can be screwed. Therefore, when the size of the product S in the left-right direction is larger than that of the chute plate 74, a chute adapter 91 having a large size in the left-right direction is appropriately selected and attached to the chute plate 74 according to the product S. By the time of sale,
The sold product S that has fallen on the chute adapter 91 can stably slide down, and can be smoothly dispensed forward from the product passage 31.

On the upper surface of the chute adapter 91,
A sheet 91a having a coefficient of friction according to the product S is attached. For example, when the product S has a very small thickness in the front-rear direction, the sheet 91 is made of a material having a small friction coefficient (for example, high-density polyethylene).
By configuring a, the product S that has fallen on the sheet 91a is easily slipped, so that the product S immediately assumes a posture inclined forward and downward. Thereby, the product passage 3
Even if the product S paid out from 1 is thin, the product S is smoothly transferred to the bucket 111 without entering the gap between the bucket 111 and the product passage 31. In the case where the product S has a small front-rear and left-right dimension and a sharp lower end, the sheet 91a is made of a material having a large friction coefficient (for example, rubber). Conversely, by making the product S less slippery, the product S is dispensed from the product passage 31 so as to fall forward from its upper end. In this case as well, the product S is smoothly delivered to the bucket 111 without entering the gap between the bucket and the product passage 31 as described above. As described above, by attaching the chute adapter 91 having the sheet 91a made of a material having an appropriate friction coefficient to the chute plate 74 according to the product S, it is possible to appropriately and variously sell the product S for the bucket. Can be delivered reliably.

On the other hand, the attitude control member 55 projects, for example, diagonally forward from the left into the product passage 31 (FIG. 9,
11), is attached to the partition wall main body 61 to control the attitude of the sales commodity S located at the forefront. This attitude control member 55 is made of a metal plate or the like, and as shown in FIG.
3 and is formed so as to become slightly thinner from the base end portion lowered by one step toward the front end portion. In addition, a plurality of notches 55a formed at different angular positions about the vertical axis are formed on the outer periphery of the base end portion. These notches 55a selectively engage with the projections 94 provided on the upper surface of the partition main body 61 when the attitude control member 55 is attached to the partition wall main body 61. In accordance with S, the posture control member 55 can be easily fixed stepwise at a plurality of angular positions about the vertical axis. Note that the attitude control of the sold product S by the attitude control member 55 will be described together with the description of the payout operation of the product S described later.

Next, the dispensing operation of the commodity S by the commodity dispensing mechanism 13 at the time of sale will be described with reference to FIGS.
This will be described with reference to FIG. It should be noted that the product S is a product hanging rod 3
2, the storage hole Sb for the product S
Are inserted into the product hanging bar 32 from the front end thereof, and are successively stored so as to be packed near the rear end of the product hanging bar 32. In this case, the hanging hole Sb of each product S is located between two adjacent upper end portions (streak portions) of the spiral convex portion 43.

When a desired product S is selected by a purchaser at the time of sale, as shown in FIGS. 9 and 10, a bucket 111 is provided in front of a product path 31 for storing the selected product S in a suspended state. Go to and stop. Then, when the cam motor 122 of the bucket 111 operates, the cam disk 121 rotates by a predetermined angle, whereby the drive gear 123 protrudes rearward and engages with the first gear 81 as shown in FIGS. Next, when the commodity feed motor 124 of the bucket 111 operates, the triangular drum 1
26 is driven to rotate, and the drive gear 123 is driven to rotate, whereby the first gear 81 rotates, and accordingly, the third gear 83 also rotates.

Then, the rotating plate 84 in the standing posture is
Rotates and assumes a horizontal posture. Thereby, the switch 52
Is turned on, the motor 4 of the rotary drive unit 33 is turned on.
2, the chute plate 74 and the slide plate 73 move to the inclined position and the transfer position, respectively. Then, by the operation of the motor 42, the product hanging rod 32 is rotated, and each of the products S suspended therefrom is rotated.
The edge of the suspension hole Sb is gradually pushed by the upper end portion of the spiral projection 43, and is sent forward.

The sales product S that has reached the front end of the product hanging bar 32 is separated from the product hanging bar 32 and falls on the shoot plate 74 or the shoot adapter 91 attached to the shoot plate 74. At the time of this fall, the selling product S is dispensed forward from the product passage 31 by sliding down on the chute plate 74 forward by the attitude control member 55 while inclining forward to the right around the vertical axis. As described above, by controlling the attitude of the sold product S at the time of falling, even if the sold product S has a small thickness in the front-rear direction, the size in the front-rear direction when being transferred to the bucket 111 is increased. The sold product S is reliably transferred to the bucket 111 without the sold product S entering the gap between the product passage 31 and the bucket 111,
Detection by the product sensor 125 can also be reliably performed.

Then, when the commodity sensor 125 detects that the commodity S has reached the opening 112a of the front bucket 111, specifically, as shown in FIG. Is interrupted for a predetermined time (for example, 5 milliseconds) in the commercial product S, the power supplied to the motor 42 of the rotary drive unit 33 is also interrupted, and the motor 42 stops. Accordingly, the rotation of the product hanging bar 32 also stops. However, the product feed motor 12
Reference numeral 4 indicates that the operation is continued for a predetermined time (for example, 300 milliseconds) after the start of the light shielding of the commodity sensor 125, and then the operation is stopped. Thereby, the product S is sent to the inside of the bucket main body 112 by the triangular drum 126 and stored therein.

In this case, the next sale item S, which is located immediately after the sale item S and becomes itself a sale item after the sale item is paid out, has a posture control member 5 on the front left side.
By abutting on 5, the posture is controlled so that the front faces substantially straight forward. As a result, the sold product S can be appropriately viewed by a purchaser or a person passing in front of the vending machine 1, and the product itself can be effectively used as a display.

After the commodity feed motor 124 stops,
After a lapse of a predetermined time (for example, 150 milliseconds), the cam motor 122 of the bucket 111 operates and the cam disc 121
Rotates to a predetermined initial position. As a result, the drive gear 123 engaged with the first gear 81 becomes
It leaves the first gear 81 and returns to its original position before projection. In addition, as the drive gear 123 separates from the first gear 81, the rotating plate 84 in the horizontal position automatically returns to the standing posture, whereby the chute plate 74 and the slide plate 73 return to the horizontal position and the standby position, respectively. . Thereafter, the bucket 111 moves to the product outlet 5,
The stored product S is carried out, and the sale is completed.

As described in detail above, according to the commodity storing and dispensing apparatus 4 of the present embodiment, the bucket 111 that moves forward of the commodity passage 31 that stores the commodity S selected at the time of sale.
By turning on the switch 52 of the product dispensing mechanism 13, the product dispensing mechanism 13 is operated, so that the structure of the product dispensing mechanism 13 can be simplified and maintenance can be performed easily as compared with the related art. be able to. The product delivery mechanism 13 is composed of two units, a rotary drive unit 33 and a partition unit 34, and these units 33, 34 are connected only by the switch harness 103, so that when one of the units fails, It is only necessary to replace the failed unit with a normal unit. In addition, since the structure of the commodity delivery mechanism 13 can be simplified, the number of parts can be reduced, and the commodity storage and delivery apparatus 4 can be manufactured at low cost as a whole.

The present invention is not limited to the above-described embodiment, but can be implemented in various modes. For example, in the embodiment, only the case where the motor of the hanging-type merchandise dispensing mechanism is operated by the switching operation by the bucket has been described, but the present invention may be applied to a pressing-type merchandise discharging mechanism. Further, the detailed configuration and the like of the product storage and dispensing apparatus shown in the embodiment are merely examples, and can be appropriately changed within the scope of the present invention.
