Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article dispensing apparatus for a vending machine which stores a plurality of articles in a stacked state and pays out the articles one by one at the time of sale.

[0002]

2. Description of the Related Art A conventional product dispensing apparatus of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. H8-77430. As shown in FIG. 12, the product dispensing device includes a plate-shaped chassis 51 that forms one of the passage walls below the product passage 4, and upper and lower stoppers 52 and 53 that are rotatably attached to the chassis 51. , Both stoppers 52, 5
3 is provided with a drive mechanism (not shown) for driving the drive mechanism 3. The upper and lower stoppers 52 and 53 are formed in a plate shape, and the lower end of the former 52 and the upper end of the latter 53 are attached to a common support shaft (not shown). It is rotatable, respectively, between an allowable evacuation position and a protruding position that protrudes into the product passage and locks the product. The height of the stoppers 52 and 53 (the length from the center of the support shaft to the free end) is substantially constant, and the stoppers 51 and 53 are provided with a chassis 51 so that the contact length when locking the product is as large as possible. In the width direction (the left-right direction in the figure).

On the other hand, the driving mechanism is provided on the back side of the chassis 51, and includes a solenoid as a driving source, a driving body driven upward by the solenoid, and upper and lower stoppers 52 interlocked with the driving body. , 53, and a return spring for returning the stoppers 52, 53, and the like. In addition, since this product dispensing device is used back to back, the drive mechanism is arranged close to one half in the width direction of the chassis 51 so as not to interfere with the drive mechanism of the other party. Reference numeral 54 in the figure denotes a sold-out detection lever for detecting whether or not one product remains.

According to this product dispensing device, during standby for sale, the solenoid is demagnetized, and the driving body is positioned lower by the spring force of the return spring, so that the upper stopper 52 is moved to the retracted position by the link mechanism. , And the lower stopper 53 is held at a protruding position in a diagonally forward lowering posture (FIG. 1).
2). As a result, the plurality of products stored in a stacked state in the product passage are held in the product passage by locking the lowest sales product in the lower stopper 53. On the other hand, although not shown, at the time of sale, when the solenoid is energized, the upper stopper 52 is actuated by the action of a link mechanism interlocked with the upward movement of the driving body.
Is driven to the projecting position. As a result, the next sale product next to the sale product is locked by the upper stopper 52, so that products equal to or greater than the next sale product are held. Further, when the lower stopper 53 is driven to the retreat position by the link mechanism, the sold product falls and is paid out.

[0005]

As described above, in the conventional product dispensing apparatus, the lower stopper 53 has a substantially constant height and extends in the width direction of the chassis 51. On the other hand, the drive mechanism for holding and driving the lower stopper 53 is arranged close to one half in the width direction of the chassis 51 for the above-described reason. For this reason, in the standby state for sale, the lower stopper 53 is firmly supported by the drive mechanism on the side on which the drive mechanism in the width direction of the chassis 51 is disposed, whereas there is no support by the drive mechanism on the opposite side. It is in a cantilever state. As a result, in the sales standby state, the weight of the product acts on the lower stopper 53 which is held at the projecting position in a diagonally forward lowering position, so that the portion opposite to the drive mechanism bends downward and enters the product path. Since the substantial protruding length of the product becomes shorter, the product may slip through the lower stopper 53 and be erroneously discharged, especially when the product is soft like a plastic bottle.

In order to solve such a problem, for example, it is conceivable to increase the height of the lower stopper 53 as a whole. However, in this case, although the product can be prevented from slipping through, the weight of the lower stopper 53 and the material cost increase in proportion to the height of the lower stopper 53, and the weight of the vending machine increases accordingly. Invite.
In addition, the lower stopper 53 depends on the weight of the lower stopper 53.
Responsiveness (rotational speed) is reduced, and in some cases, it is necessary to strengthen the solenoid and the return spring of the drive mechanism for driving the same.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide an article dispensing apparatus for a vending machine which can reliably prevent a commodity from slipping in a standby state for sale with a simple configuration. It is intended to provide.

[0008]

In order to achieve this object, the present invention is directed to a plurality of products provided in a lower portion of a product passage extending vertically and stored in a state of being stacked in the product passage at the time of standby for sale. And at the time of sale,
A vending machine dispensing device for dispensing the lowest sales product of a plurality of products downward, comprising a plate-shaped chassis extending in a vertical direction, and a rotatably attached to the chassis, the width of the chassis being An upper and lower stopper that extends in the direction, protrudes into the product passage, locks the product, and is retractable from the product passage and is rotatable between a retracted position that allows the product to pass therethrough; It is arranged in one half in the width direction on the rear surface side of the chassis, and controls the upper and lower stoppers at the retracted position and the protruding position at the time of sales standby by control by the control means.
A drive mechanism that drives the upper stopper to the protruding position and enables the lower stopper to move to the retracted position. The lower stopper has a drive mechanism in which the height of a portion opposite to the drive mechanism in the width direction is arranged. It is characterized by being formed larger than the height of the side part.

According to the commodity dispensing device of the vending machine of the present invention, the upper and lower stoppers are held at the retracted position and the projected position by the drive mechanism at the time of standby for selling, and a plurality of stacked commodities are removed. The lowest sales product is retained in the product passage by being locked by the lower stopper at the projecting position. On the other hand, at the time of sale, the upper stopper is driven to the projecting position by the drive mechanism to lock the next sale product next to the sale product, and the lower stopper is made movable to the retracted position, so that the sale product is released. Passes through the lower stopper and is dispensed. From the above,
Items are paid out one by one.

In the present invention, the lower stopper has a portion opposite to the drive mechanism in the width direction, which is larger than the height of the portion on which the drive mechanism is disposed. Even if it is bent by the weight of the product because it is not supported by the drive mechanism, it is possible to secure a sufficient projecting length into the product passage for locking the product for sale. This makes it possible to reliably prevent the product from slipping through in the sales standby state. In addition, since the height of the lower stopper is partially increased only at a necessary portion, the above-described operation can be performed while minimizing the increase in the weight of the entire lower stopper and the resulting decrease in the responsiveness of the lower stopper. Can be obtained effectively.

In this case, the system further includes a sold-out detecting means for detecting whether or not the number of the goods stored in the goods passage is one, and the control means controls the goods according to the detection result of the sold-out detecting means. It is preferable to control the drive mechanism such that when the number is one, the time during which the lower stopper is located at the retracted position is longer than when the number is not one.

In this configuration, when the sold-out detecting means detects that the remaining number of the commodities is one, the control means sets the time during which the lower stopper is located at the retracted position.
It is controlled to be longer than when the number of remaining products is two or more. When the number of remaining commodities is one, the pressing force due to the weight of the upper commodities does not act on the commodities at all, so that the response of the selling commodities to the movement of the lower stopper to the retreat position is particularly low. Therefore, there is the highest possibility that non-payment (non-sale) of the sold product will occur. Conversely, there is no danger of taking out two products.

Therefore, when the number of remaining products is one, the above-described control allows the lower stopper to be moved for a longer time.
By keeping the product at the evacuation position, the last product can be reliably paid out. In addition, since the sold-out detection means as described above is usually provided in a vending machine as a sold-out detection lever, according to the present invention, only the control is changed by utilizing the detection result, and The function can be easily obtained.

It is pivotable. On the back surface of the upper stopper 12, a pair of left and right engagement grooves 12a, 12a is formed.
a has a predetermined width and extends obliquely rearward and upward.

The lower stopper 13 is formed by bending a plate material such as a steel plate. The lower stopper 13 is disposed at the full width of the opening 27 of the chassis 11 like the upper stopper 12, and is rotatable about the support shaft 22 at the upper end. Supported. With this configuration, the lower stopper 13 is
It is rotatable between a projecting position (the position in FIGS. 3 and 4) that projects into the product passage 4 in a diagonally forward-downward position and a retracted position (the position in FIG. 5) that retreats from the product passage 4. Further, at the lower end of the lower stopper 13, a bent portion 13a bent backward is formed to increase its rigidity, and as shown in FIG. 3, its left end, that is, the drive mechanism 14 and the solenoid The end opposite to the side where 15 is arranged is a protruding portion 13b protruding downward,
Accordingly, the height is formed larger than other portions.

The solenoid 15 is formed flat and thin,
The chassis 11 is disposed above the upper stopper 12.
And a plunger 15a extending downward from the solenoid body 15b. The plunger 15a is configured to hang down from the solenoid body 15b in a free state when the solenoid 15 is demagnetized, and to be attracted and lifted by the solenoid body 15b when excited. The solenoid body 15b includes an electronic control unit (ECU) 2 as a control unit.
The excitation and demagnetization of the solenoid 15 are controlled by a drive signal from the ECU 29. An engagement hole 15c is formed at the tip of the plunger 15a, and a drive plate 23 of the drive mechanism 14, which will be described later, is engaged with the engagement hole 15c.

The drive mechanism 14 includes a drive plate 23, upper and lower drive rods 24 and 25, and a lock member 26 for locking the lower stopper 13 at the projecting position. The drive plate 23 is formed by partially bending a plate material such as a steel plate, and a bent portion 23a formed at an upper end thereof is engaged with the engagement hole 15c of the plunger 15a of the solenoid 15 from behind. Further, both upper side portions of the drive plate 23 are bent forward to form rod insertion holes 23b, 23b, and the upper drive rod 24 is connected to the drive plate 23 by the rod insertion holes 2b.
3b and 23b, it is horizontally mounted in a state of protruding on both left and right sides. As shown in FIG. 4, the upper drive rod 24 is almost exactly engaged with each engagement groove 12a of the upper stopper 12.

Further, a curl portion 23c is formed at a lower end portion of the drive plate 23, and the lower drive rod 25 is engaged with the curl portion 23c, and the lower drive rod 25 projects horizontally to both right and left sides of the drive plate 23. Installed. As shown in FIG. 4, the lower drive rod 25 is engaged with the lower curl portion 23c with a predetermined play P1 in the vertical direction. The upper and lower drive rods 24 and 25 have their right ends respectively engaged with upper and lower guide grooves (not shown) formed in the support shaft mounting portion 28 and extending in the up and down direction. Are respectively engaged with the upper and lower guides 30 and 31 attached thereto, and are guided vertically by these. The return spring 16 is formed of a coil spring, is connected between the chassis 11 and the lower drive rod 25, and keeps the drive plate 23
It is biased downward.

With the above configuration, the drive plate 23 is driven by the upper and lower drive rods 24 and 25 while the upper and lower drive rods 24 and 25 are guided by the upper and lower guide grooves and the guides 30 and 31 of the support shaft mounting portion 28. Move up and down with. The drive plate 23 and the upper and lower drive rods 24, 25
When the solenoid 15 is demagnetized, the return spring 1
6 while the solenoid 15 is energized, the return spring 16
Is driven upward by being pulled up by the plunger 15a against the urging force.

The lock member 26 is made of plastic or the like, and has left and right rear connecting portions 26a, 2a at its rear end.
6a is rotatably connected to the lower drive rod 25, and the left and right front connecting portions 26b, 26b (only one is shown in FIG. 4) of the front end are fixed to the lower end of the lower stopper 13. 13c is rotatably connected.

Further, the lever mounting opening 1 of the chassis 11
A sold-out detection lever 32 is rotatably attached to 1a. The sold-out detection lever 32 is constantly urged toward the product passage 4 by a torsion coil spring 33. When two or more products A are present in the product path 4, the sold-out detection lever 32 is pressed by the next-sold product A2,
Switch 34 is turned off by retracting from product passage 4
On the other hand, when the remaining product A is only one, that is, only the sold product A1, or when the product A is gone, the sold-out detection lever 32 projects into the product passage 4 by the biasing force of the torsion coil spring 33, and turns on the switch 34. Thus, the state is detected.

Next, with reference to FIGS. 4 to 6, the dispensing operation of the commodity dispensing apparatus 5 having the above-described configuration will be described. The basic dispensing operation of the commodity dispensing apparatus 5 is the same as that of the conventional commodity dispensing apparatus of FIG. That is, in the sales standby state shown in FIGS.
Are demagnetized, and the plunger 15a and the driving plate 23
Is located at a predetermined lower position by the urging force of the return spring 16. Thus, the upper drive rod 24 holds the upper stopper 12 at the retracted position in a state where the upper drive rod 24 is in contact with the bottom surface of the engagement groove 12a of the upper stopper 12. The lower stopper 13 protrudes into the product passage 4 at an angle before the dead center of the lock member 26, and is thereby held at the protruding position in an obliquely forward lowered position while being locked by the lock member 26. ing. The plurality of products A stored in a stacked state in the product passage 4 are held in the product passage 4 by locking the lowest sales product A1 to the lower stopper 13.

As described above, in the present embodiment, the lower stopper 13 has the protrusion 13b formed at the left end thereof, that is, at the end opposite to the side where the drive mechanism 14 and the solenoid 15 are disposed. This part is higher than the other parts. Therefore, in the standby state for sale, even if the opposite portion including the protruding portion 13a of the lower stopper 13 is bent by the weight of the product A because it is not supported by the lock member 26 or the like, the sales product A1 is engaged. Enough to stop,
A protruding length into the product passage 4 can be secured. Therefore,
It is possible to reliably prevent the sale product A1 from slipping through in the sale standby state. Further, since the height of the lower stopper 13 is partially increased only at a necessary portion, the weight of the entire lower stopper 13 is increased, the weight of the vending machine is increased, and the response of the lower stopper 13 is improved. The above advantages can be effectively obtained while minimizing the reduction.

On the other hand, at the time of sale, the solenoid 15 is excited from the above-mentioned sale standby state, so that the drive plate 2
3 is pulled up by the plunger 15a against the urging force of the return spring 16. Thereby, as shown in FIG.
The upper drive rod 24 presses the wall of the upper stopper 12 on the product passage 4 side of the obliquely extending engagement groove 12a,
The upper stopper 12 is driven to the projecting position. Further, the rear connecting portion 26a of the lock member 26 is pulled up by the lower drive rod 24, and the lock member 26 rotates beyond the dead center, whereby the lock of the lower stopper 13 by the lock member 26 is released. As a result, the lower stopper 13 is placed on the sales item A1.
By turning to the retreat position with the weight of, the sold product A1 passes through the lower stopper 13 and is paid out.

As described above, in this embodiment, the lower drive rod 25 is attached to the curled portion 23c of the drive plate 23 with a play P1 in the vertical direction. For this reason, as shown in FIG. 6, since the size of the product A is large, during the dispensing, after the lower stopper 13 is unlocked,
Before the lower stopper 13 reaches the retreat position, the sales product A1
Even if the drive plate 23 cannot be lifted due to the contact of the upper stopper 12 with the upper stopper 12, the lower drive rod 25 has a play P1 with respect to the drive plate 23, so
Accordingly, the lower drive rod 25 can move upward with respect to the drive plate 23. Then, the lower stopper 13 pivots toward the retreat position side by the movement of the lower drive rod 25, and the opening angle between the lower stopper 13 and the upper stopper 12 increases, so that jamming of the product can be prevented, and the product can be paid securely. Can be put out.

Subsequently, when the solenoid 15 is demagnetized,
By the urging force of the return spring 16, the lower stopper 13 returns to the projecting position and the upper stopper 12 returns to the retracted position, and is held by the operation reverse to the above. As a result, the plurality of commodities A are entirely lowered, are locked and held by the lower stopper 13, and enter the next sales standby state.

FIG. 7 shows a modification of the first embodiment. This modification is different from the above-described embodiment in that the shape of the front surface (the surface on the side of the product passage 4) of the upper stopper 12 is different. That is, as is clear from the comparison between FIG. 6 and FIG. 7, in the above-described embodiment, the front surface of the upper stopper 12 is constituted by the flat portion 12b and the projection 12c of the upper end projecting forward from the upper end. Therefore, a gap C is generated between the product A and the sales product A. On the other hand, in the modified example, the front surface of the upper stopper 12 has a gently curved surface portion 12d having a curvature matching the assumed diameter of the product A, and an extension line of the curved surface portion 12d via a concave portion 12e at the upper end thereof. The projection 12f is formed so as to protrude from the projection 12f. As a result, as shown in FIG. 7, the gap C in FIG. 6 between the upper stopper 12 and the product for sale A1 is eliminated, and the opening angle of the upper and lower stoppers 12 and 13 during the dispensing of the product A increases accordingly. Since the size of the product A becomes large, jamming of the product A having a larger diameter can be prevented, and the payout can be reliably performed.

FIGS. 8 and 9 show a commodity dispensing apparatus according to a second embodiment of the present invention. In this embodiment, as compared with the first embodiment, by increasing the width of the engagement groove 12a of the upper stopper 12, the upper drive rod 24 is positioned in the engagement groove 12a in a predetermined vertical direction in the standby state for sale. The difference is that they are engaged with play P2.

Therefore, in this embodiment, the play P
According to 2, the timing of turning the upper stopper 13 to the projecting position side with respect to the elevation of the drive plate 23 due to the excitation of the solenoid 15 at the time of sale can be delayed as a whole. As a result, as shown in FIG. 9, the opening angle between the stoppers 12 and 13 during the dispensing of the product A further increases, so that the play P between the driving plate 23 and the lower driving rod 25 is increased.
Combined with the operation according to 1, the jamming of the product A can be more reliably prevented, and the product A can be paid out more reliably.

FIG. 10 shows a modification of the second embodiment. In this modification, in the second embodiment, an upper stopper 13 having a different front surface shape as shown in FIG. 7 is used. Therefore, in this modified example, it is possible to pay out the commodity A having a larger diameter than in the case of FIG.

FIG. 11 is a flowchart showing a control process of the solenoid 15 and the like executed by the ECU 29. In this control process, the excitation time of the solenoid 15 is set according to the remaining status of the product A. First, in step 1 (shown as "S1"; the same applies hereinafter), it is determined whether or not the sales condition of the product A is satisfied, that is, whether or not a required amount of money has been inserted and the product has been selected. If the sales conditions are not satisfied, the program ends.

When the sales conditions are satisfied, it is determined whether or not the sold-out detection lever 32 is in the ON state (step 2). When the sold-out detection lever 32 is OFF, that is, when the number of remaining products A is two or more, the excitation time tsol of the solenoid 15 is set to a predetermined time TSOLS (for example, 0.09 seconds) (step 3). On the other hand, when the sold-out detection lever 32 is ON according to the determination in step 2, that is, when the remaining number of the product A is one, the flag FLEV is set to "1" (step 4).
The excitation time tsol of the solenoid 15 is set to the predetermined time T
The predetermined time TSOLL (for example, 0.1
8 seconds) (step 5).

Next, a drive signal is output to the solenoid 15 based on the excitation time tsol set in step 3 or step 5 (step 6), thereby exciting the solenoid 15 over the excitation time tsol. Next, it is determined whether or not the flag FLEV is "1" (step 7). If the answer is NO, the program is terminated. On the other hand, when the flag FLEV = 1, it is determined that the last one product A has been sold in the current sale, and a sold-out lamp (not shown) is turned on (step 8), and the program ends.

As described above, according to this control processing, when the sold-out detection lever 32 detects that the remaining number of the goods A is one, the excitation time t of the solenoid 15 is set.
By setting sol to a longer predetermined time TSOLL, the time during which the lower stopper 13 is located at the retracted position is reduced.
The product A is controlled so as to be longer than when the remaining number is two or more. If there is only one item left for product A,
Since the pressing force due to the weight of the higher order product A does not act on the sale product A1 at all, the responsiveness of the sale product A1 falling to the movement of the lower stopper 13 to the retreat position is particularly low. Also, in this case, there is no possibility that two products A will be taken out. Accordingly, the last product A can be reliably paid out by the above control. Also, since the sold-out detection lever 32 is usually provided in a vending machine,
The above effects can be easily obtained only by changing the control using the detection result.

[0039]

As described above, in the commodity dispensing apparatus of the vending machine according to the present invention, in the sales standby state, the projecting length of the portion opposite to the drive mechanism of the lower stopper can be sufficiently secured, so that the commodity can be discharged. Even if the material is soft, there is an effect that the slip-through of the product in the standby state for sale can be reliably prevented by a simple configuration.
