2. Description of the Related Art Vending machines are frequently used as devices for unmanned sales of beverages such as beer and juice. By the way, three types of beverage cans, such as beer and juice, are commonly used, which are called thick cans, medium thick cans, and thin cans. In recent years, beverages in PET bottles have also been sold by vending machines. Furthermore, drinks containing vitamins and the like are manufactured and sold exclusively in bottles, and these bottled drinks are also sold by vending machines. Therefore, it is important that a vending machine can handle a plurality of types of products having different diameters and shapes.

Here, generally, a member for performing a wing operation called a flapper is used in a product discharging device of a vending machine, and the member is projected to a product passage side to prevent the product from falling. The product is discharged by storing the flapper on the wall side. As described above, the flapper of the product ejection device is an obstacle in the product passage.However, in order to stop the products reliably and to eject the products one by one, the diameter of the product and the flapper are required. It is necessary to adjust the relationship between the length and the width of the product path. Therefore, in order to discharge products of a plurality of diameters, it is necessary to change the length of the flapper according to the product, or to change the width of the product passage. However, it is not easy to change the length of the flapper at the vending machine installation site. Therefore, in the related art, a measure is adopted in which the width of the product passage is changed so as to correspond to a plurality of types of products. In addition, in this type of vending machine, the main flapper holds the product located at the lowermost position (the most downstream side), and the next flapper temporarily holds the second product when the flapper retreats. Although it has a product holding flapper, the operation of the two flappers is linked in the prior art.

Hereinafter, a conventional product dispensing apparatus for a vending machine will be described with reference to the drawings. FIG.

On the other hand, the auxiliary support member 26 is frame-shaped and has a large rectangular opening 35 at the center. The length of the opening 35 is longer than the length of the upper flapper 22 described above. A shaft hole 36 is formed on one side of the auxiliary support member 26.

Next, the lower flapper 23 as a main product support member
Will be described. Lower flapper 2 as main product support member
Reference numeral 3 denotes a metal flapper member 37 and a resin joining member 38 integrated with each other. That is, the flapper member 37 is made of metal and has a rectangular plate shape. A shaft hole 40 is provided on one side thereof.

On the other hand, the joint member 38 is provided with a shaft hole 41 on one side of the plate-like portion 43 and a guide portion 44 on the lower surface.
Is provided. The guide part 44 is a plate-like part 43.
And a guide groove 45 is formed in a plane perpendicular to the plane of FIG. The guide groove 45 has an arc shape as shown in FIG. Metal flapper member 37 and resin joining member 3
8 are integrated by a fitting structure (not shown),
The shaft hole 40 of the flapper member 37 and the shaft hole 41 of the joining member 38
Communicate.

In this embodiment, the retraction preventing member 25 is constituted by two links A and B. Link A is
It has two parallel belt-shaped members 61a and 61b, which are arranged facing each other, and a concealing plate 62 is welded to one surface side (product passage side). The link B is a two band-shaped member.

The interlocking member 28 is a plate-shaped member. A hook 47 is provided at a lower portion, and a shaft 48 is inserted through an intermediate portion. The interlocking member 28 is connected to a solenoid 27 provided on the frame 21 and moves up and down with respect to the frame 21.

Next, the assembly structure of each member will be described. Each of the above members is attached to the frame 21. That is, the upper flapper 22 is provided at a position that covers the opening 101 of the frame 21, the shaft 50 is inserted into the shaft hole 32 of the main body 30, and the upper flapper 22 is swingably attached to the frame 21. Here the upper flapper 22
The shaft 50 is inserted through the lower part of the shaft, and the upper side is a free end. Also, a stopper not shown is provided,
The upper flapper 22 swings within a range of about 30 ° from the vertical. When the upper flapper 22 is attached to the frame 21, the guide groove 31 on the back side of the upper flapper 22 is located on the back side of the frame 21. The shaft 48 of the connecting member 28 is engaged with the guide groove 34 of the guide groove 31.

The auxiliary support member 26 is also attached to the frame 21 by inserting the shaft 51 into the shaft hole 36 provided on one side. Here, the auxiliary support member 26
Has a shaft 51 inserted through its upper part, and the lower side is a free end. A stopper (not shown) is also provided for the auxiliary support member 26, and swings in a range from a vertical posture to a horizontal posture. The auxiliary support member 26 is urged by a spring 54 so as to be always in a horizontal posture. That is, the auxiliary support member 26 is constantly urged in the protruding direction. The means for urging the auxiliary support member 26 is not limited to a spring, but may use another elastic body.

The auxiliary support member 26 and the upper flapper 22
In the positional relationship, the swing shaft 51 of the auxiliary support member 26 is located at the upper part, and the swing shaft 50 of the upper flapper 22 is located at the lower part. The lower end of the auxiliary support member 26 swings in the protruding direction with respect to the frame 21, and the upper flapper 22 swings in the upper direction with respect to the frame 21. When the upper flapper 22 is stored, that is, in a closed state, the height of the upper end of the upper flapper 22 is
6 corresponds to the height of the swing shaft 51. Therefore frame 2
In a state where the upper flapper 22 is attached to the first flapper 22, the swing trajectories of the upper flapper 22 and the auxiliary support member 26 intersect with each other when viewed from the side.

However, as described above, the auxiliary support member 26 is frame-shaped and has an opening 35, and the length of the opening 35 is longer than the length of the upper flapper 22. 26 completely enters the opening 35. Therefore, when viewed from the side, the swing trajectories of the upper flapper 22 and the auxiliary support member 26 intersect,
Regardless of the position of the auxiliary support member 26, the upper flapper 22
Can swing over the entire swing range.

On the other hand, the operation range of the auxiliary support member 26 is restricted by the position of the upper flapper 22. That is, when the upper flapper 22 is in the vertical state, the tip of the upper flapper 22 engages with the tip of the auxiliary support member 26, and the auxiliary support member 26 cannot swing while maintaining a horizontal posture. When the upper flapper 22 is in the most protruding state, the inner side of the frame 56 on the tip side is the upper flapper 2.
It is engaged with and fixed to the second protrusion 57.

Next, the assembly structure of the lower flapper 23 will be described. The lower flapper 23 is attached at a position lower (downstream) of the upper flapper 22 described above. That is, the lower flapper 23 has the shaft 58 inserted into both the shaft hole 40 provided in the main body and the shaft hole 41 provided in the joining member 38, and is attached to the frame 21 so as to be swingable. The distance between the position of the shaft 58 for swinging the lower flapper 23 and the shaft 51 for swinging the auxiliary support member 26 is substantially equal to the diameter of the thin can 77 as shown in FIG. In other words, the distance between the position of the shaft 58 for swinging the lower flapper 23 and the shaft 51 for swinging the auxiliary support member 26 is substantially equal to the smallest of cans or bottles to be sold, Preferably, this distance is in the range of ± 10% of the smallest diameter cans and the like.

In this embodiment, the lower flapper 23 has a shaft 58 inserted in the upper part thereof, and the lower side is a free end. Further, a stopper (not shown) is provided, and the lower flapper 23 swings in a range from vertical to substantially horizontal. The lower flapper 23 is urged by an urging means including a spring 59 (FIG. 1) so that the lower flapper 23 always assumes a substantially horizontal posture. That is, the lower flapper 23 is constantly urged in the protruding direction by the spring 59 and maintains a horizontal posture. It is desirable that the posture of the lower flapper 23 be inclined within a range of about 20 ° from horizontal, more preferably, within a range of about 15 ° to 20 °. In this case, the inclination direction is downward on the free end side, and upward on the swing center. The reason for setting the free end side downward is to bring the product to the wall side facing the product discharging device 20 and keep the product away from the swing range of the auxiliary support member 26. The means for urging the lower flapper 23 is not limited to a spring, but may use other elastic bodies.

The distal end of the link A is engaged with the guide groove 45 of the lower flapper 23 via the pin 60. Therefore, the tip of the link A is slidable along the guide groove 45 and can also rotate via the pin 60. The other end of the link A is pivotally fixed by a pin 63 to a hole 105 provided in a part 65 of the frame.

The tip of the link B is attached to the intermediate portion of the link A via a pin 64. On the other hand, link B
A shaft 66 is inserted through the rear end of the frame, and the shaft 66 is engaged with a guide groove 67 provided in a part 65 of the frame. The guide groove 67 is slightly curved and extends substantially in the vertical direction. Therefore, the rear end side of the link B moves substantially vertically along the guide groove 67. The lower end of the hook 47 of the interlocking member 28 can be engaged with the shaft 66 inserted through the link B as shown in FIG. However, hook 4 of interlocking member 28
Although 7 is on the lower end side of the shaft 66, both are not integral. More specifically, when the hook 47 is raised, the shaft 6
6 is moved up by being hooked on a hook, but the shaft 66 can also rise alone.

The positional relationship between the lower flapper 23 and the links A and B is as shown in FIG. 2. The link A is located in the tangential direction of the swing locus. Therefore, the force received from the lower flapper 23 acts only on the link A in the axial direction, the link A does not swing, and holds the lower flapper 23 in a substantially horizontal posture. At this time, the link B is located in the tangential direction of the swing trajectory of the link A about the swing center 64 of the link A. That is, the link B is located in a direction perpendicular to the direction in which the link A breaks the above relationship. More specifically, the link A is on the frame 21 side (the side wall side of the product passage).
Moves to, the lower flapper 23 cannot be supported,
The link B prevents the link A from moving to the frame 21 side. In this embodiment, the force received from the link A acts only on the link B in the axial direction, and the link B does not swing. That is, the link A prevents the lower flapper 23 from moving, and the link B prevents the link A from moving.

On the other hand, if the rear end side of the link B moves to break these relationships, the posture of the lower flapper 23 cannot be maintained. That is, when the rear end side of the link B slightly moves upward, a force in the lateral direction (oscillation direction) acts on the link B by the force received from the link A, and the rear end side of the link B further rises by the force. As a result, the link A coupled to the link B swings. That is, link A
The pin 60 on the tip side of the guide groove 45 of the lower flapper 23
And the inclination angle with respect to the lower flapper 23 changes. Therefore, a force in the swing direction is generated on the link A by the force received from the lower flapper 23, and the link A moves in the closing direction. As a result, the lower flapper 23 moves in the storage direction.

The above described vending machine product dispensing apparatus 20
Is the product passage 2 of the vending machine as shown in FIGS.
Attached to the bottom of The opposite wall 10 of the product passage 2
In FIG. 6, a wall-side projection 70 is provided at a position corresponding to the highest height of the upper flapper 22 when the upper flapper 22 protrudes as shown in FIGS. Wall side projection 7
The cross-sectional shape of 0 is a substantially right triangle as shown in FIGS. That is, the lower part of the protruding end 110 is
1 and the upper part is a relatively gentle sloped wall 112
It has become. The inclined wall 112 of the wall-side projection 112 forms an inclined surface (inclined portion) 112 that is inclined so that the amount of protrusion gradually increases from the upstream side to the downstream side. The angle of the inclined surface, that is, the inclination angle θ of the inclined wall 112 is 1
5 ° or less, more preferably 12 ° or less. On the other hand, the frame 21 of the product discharging device 20 also has the product discharging device side protrusion 71 as described above, and the heights of both protrusions 70, 71 are in a stepped state. That is, the projection 70 on the opposite wall side of the product passage and the product projection device-side projection 71 on the product projection device 20 are at approximate heights, and the projection 71 on the product projection device 20 is at a slightly higher position. Note that the wall-side projection 11
The height of 2 and the height of the product ejection device side projection 71 are substantially equal. Specifically, the difference between them is 15% or less, and a specific numerical value is 2 mm or less. A more recommended difference between the two is 1.5 mm or less.

Here, a detailed description will be given of the positional relationship between the product discharging device 20 of the present embodiment and each part of the facing wall 106 of the product passage.
Distance Wa between the protrusion 71 provided at 0 and the opposing wall 106
Is 85% or more and less than 95% of the width W of the product passage 2.
Further, the protruding end 1 of the wall-side projection 70 provided on the facing wall 106.
10 and a product dispensing device 20 at a position opposed thereto
Is 85% or more and less than 95% of the width W of the product passage 2. Further, the shortest distance Wc between the projection 71 provided on the product discharging device 20 and the projection 70 on the opposite wall side is also 85% or more and less than 95% of the width W of the product passage. In addition, the shortest distance Wd between the auxiliary support member 26 and the protruding end 110 of the wall-side projection 70 in a state where the upper flapper (next product support member) 22 protrudes is 65 times the width W of the product passage 2.
% Or less.

The position and height of the protruding end 110 of the wall-side projection 70 and the positional relationship of the lower flapper (main product support member) 23 are as follows. When the cylinder is supported, a part of the cylinder comes into contact with the protruding end 110 of the wall-side projection 70. Is also the wall side projection 70
Are not in contact with the protruding end portion 110 of the main body. Product passage 2

Is a size corresponding to the average diameter of a target small-diameter product (thin can). Tip 110 of wall-side projection 70
Position and height and lower flapper (main product support member) 23
By setting the positional relationship as described above, both the target large-diameter product and the target small-diameter product can be smoothly discharged.

Next, the overall operation of the commodity dispensing apparatus 20 of the vending machine of this embodiment will be described. FIG. 5 shows a state in which a large can is discharged by the product discharging device 20 of the vending machine of the present embodiment. When the product discharging apparatus 20 of this embodiment is used for discharging a large can, the can 72 at the lowermost end is supported by the lower flapper 23 as shown in FIG.
When the large can 72 is placed on the lower flapper 23, the large can 72
Of the wall-side projection 7, more specifically, about 10 ° to 20 ° above a horizontal axis passing through the central axis of the thick can 72.
0 is in contact with the tip 110. In this example,
The thick can 72 is supported at three points of the protruding end 110 of the wall-side projection 70, the lower flapper 23, and a part of the product discharging device 20, and does not contact the opposed wall 106 of the product passage.

The positional relationship between the lower flapper 23 and the links A and B at this time is as described above.
The link A is located in the tangential direction of the swing locus of No. 3, and the link B is located in the tangential direction of the swing locus of the link A with the swing center 64 of the link A as the center. Therefore, the load of the large can is blocked by the link A, and the link A
Are fixed by link B. Therefore, the lower flapper 23 maintains a substantially horizontal posture, and the thick can does not fall.

At this time, the upper flapper 22 is in a vertical position and is retracted. The auxiliary support member 26 includes a spring 5
4, it is pushed in the protruding direction by the thick can 72 and is in a retracted posture as shown in FIG.

Subsequently, by inserting coins and selecting commodities,
When a predetermined signal is issued, the solenoid 27 functions to pull up the interlocking member 28. At this time, the hook 47 provided at the lower end of the interlocking member 28 raises the shaft 66 that is the center of swing of the link B. Then, link B and link A
Is broken, a force in the lateral direction (oscillation direction) acts on the link B by the force received from the link A, and the link B
The rear end side is further raised by the force. That is, the hook 47 of the interlocking member 28 merely hooks the shaft 66, and the shaft 66 can move upward by leaving the hook 47.
Rise faster than rise. Then, the link A swings along with the link B, and the pin 60 on the distal end side of the link A moves along the guide groove 45 of the lower flapper 23, and the inclination angle with respect to the lower flapper 23 changes. Therefore, the lower flapper 23 is pushed open by the load of the large can. As a result, the thick can 72 located at the lowermost position falls and the product is discharged.

Then, the interlocking member 28 is continuously pulled up by the solenoid 27, and the positional relationship between the shaft 48 interlocking with the interlocking member 28 and the guide groove 34 of the upper flapper 22 changes. Move. That is, the upper flapper 22 protrudes as shown in FIG. As described above, the auxiliary support member 26 is frame-shaped and has an opening 35, and the length of the opening 35 is longer than the length of the upper flapper 22.
Completely enters the opening 35 of the auxiliary support member 26, and regardless of the position of the auxiliary support member 26, the upper flapper 22 can swing over the entire swing range.
The upper flapper 22 can project without obstruction. As a result, the protruding end 57 of the upper flapper 22 comes into contact with the second can 73 from the bottom, thereby preventing the can 73 from dropping.

The state of the thick can 73 at this time is as shown in FIG. 5B. The thick can 73 is composed of the flat portion 108 of the projection 71 of the product discharging device 20 and the wall-side projection 70 of the facing wall 106. Of the upper flapper 22 and is stabilized.

As described above, since the can 73 is held by the upper flapper 22 and the lower flapper 23 has no load, the lower flapper 23 returns to the horizontal position by the force of the spring 59. In addition, the link A is located in the tangential direction of the swing trajectory of the lower flapper 23, and the link B is located around the swing center 64 of the link A in the tangential direction of the swing trajectory of the link A and is stable. Then, when the discharge of the bottom product is confirmed, the solenoid 27 returns, and the upper flapper 22 returns.

When the upper flapper 22 returns, the can 73
In the present embodiment, since the projections 70 and 71 are provided on both the product discharging device 20 and the opposing wall 106, the can 73 has a slightly zigzag shape. And is placed on the lower flapper 23. That is, in the present embodiment, the projection 71 on the product ejection device 20 side and the wall-side projection 70 are in a stepped state, and the projection 71 on the product ejection device 20 side is at a position slightly higher than the wall-side projection 70. is there. The projection 70 on the side of the facing wall 106 has a substantially right-angled triangular cross section as shown in FIGS.
It is 2. Further, the distance Wa between the protrusion 71 provided on the product discharging device 20 and the opposing wall 106 is 85% or more and less than 95% of the width W of the product passage 2 and is narrower than other portions of the product passage 2. Have been. Further, the distance Wb between the protruding end portion 110 of the wall-side projection 70 provided on the facing wall 106 and the product dispensing device 20 at a position facing the protruding portion 110 is 85% or more and less than 95% of the width W of the product passage 2. Yes, it is regulated to be narrower than other parts of the product passage 2.

For this reason, when the upper flapper 22 returns, the can 73 is inclined by the inclined wall 112 of the wall-side projection 70 on the facing wall 106 side.
Move toward the product discharging device 20 along the line. And can 73
Passes through the portion of the shortest distance Wc between the projection 71 provided on the product discharging device 20 and the wall-side projection 70, and reaches the lower portion. Here, in the present embodiment, the shortest distance Wc between the projection 71 provided on the product discharging device 20 and the wall-side projection 70 also has a width of 85% or more and less than 95% of the width W of the product passage.
Even relatively thick cans can easily pass through.

In this embodiment, since the free end side of the lower flapper 23 is inclined downward at an angle of about 20 ° from the horizontal, the can 73 moves to the facing wall 106 side. As a result, the can 73 moves slightly zigzag and is placed on the lower flapper 23.

The above is the operation for selling thick cans. Next, the operation for selling square PET bottles will be described. As a precaution when selling a square plastic bottle, it is possible to discharge the square plastic bottle without rotating it. In other words, the contact relationship between the cylindrical can and the product passage and the flappers 22 and 23 does not change, regardless of the rotation posture when falling down the product passage. The contact relationship changes significantly. For example, when the square PET bottle falls at the corner first, the corner of the square PET bottle comes into contact with the lower flapper 23 and is supported in an unstable state. For this reason, it is desirable to drop an angular product such as a square plastic bottle such that the flat portion is at the bottom. Therefore, in the present embodiment, the inclined wall 112 of the wall-side projection 112 is made gentle at 15 ° or less so that the square plastic bottle does not rotate. That is, according to the study of the present inventors, when the rate of change (gradient) of the wall-side projection 112 is sharp, the corner of the square PET bottle is caught by the wall-side projection 112, and the difference in the falling speed of both sides of the square PET bottle is different. Occurs. Therefore, it turned out that a square plastic bottle rotates and a corner part becomes the lowest part. On the other hand, when the angle of the inclined surface is 15 ° or less with respect to the product passage, the frequency of the rotation of the product is extremely low. That is, when the angle of the inclined surface is small, there is little difference in the falling speed between the both sides of the square PET bottle, and the square PET bottle does not rotate. When the angle of the inclined surface is 15 ° or less with respect to the product passage, the rotation angle is small even if the square plastic bottle is rotated,
When the square plastic bottle comes into contact with the lower flapper 23, it naturally returns to the original posture. On the other hand, if the angle of the inclined surface exceeds 15 ° with respect to the product passage, the square PET bottle may not return to the normal posture once every several tens of times. Therefore, in the present embodiment, the inclined wall 11 of the wall-side projection 112 is
2 has a gentle angle of 15 ° or less to prevent rotation of the square PET bottle.

The basic operation of selling a square PET bottle is as shown in FIG.
Are supported by the lower flapper 23, and at this time, the upper flapper 22 is in a vertical position and is retracted. In addition, the auxiliary support member 26 is pushed by the square
It is in the retracted position as shown in FIG.

Subsequently, by inserting coins and selecting commodities,
When a predetermined signal is issued, the solenoid 27 functions and the interlocking member 28 is pulled up, the above-mentioned relationship between the link B and the link A is broken, and the force received from the link A causes the link B to move in the lateral direction (the swing direction). A force acts, and the rear end side of the link B further rises by the force, and the lower flapper 23 moves in the pushing and opening direction by the load of the square PET bottle. Therefore, the square PET bottle 74 located at the lowermost position falls and the product is discharged.

Then, the interlocking member 28 is continuously pulled up by the solenoid 27, the positional relationship between the upper flapper 22 and the guide groove 31 is changed, and the upper flapper 22 is projected, so that the square PET bottle 75 is prevented from dropping.

Therefore, the lower flapper 23 has no load and returns to the horizontal position by the force of the spring 59. The link A is located in the tangential direction of the swing trajectory of the lower flapper 23,
Further, the link B is stabilized in the tangential direction of the swing trajectory of the link A about the swing center 64 of the link A. Then, when the discharge of the bottom product is confirmed, the solenoid 27 returns, and the upper flapper 22 returns. As a result, the square PET bottle 75 moves slightly zigzag, falls down on the lower flapper 23, and is supported by the lower flapper 23.

Next, the operation for selling thin cans will be described with reference to FIG. The operation when selling thin cans is significantly different from the case of thick cans and the like. That is, when the product discharging device 20 of the present embodiment is used for discharging thin cans, FIG.
The lowermost can 76 is supported by the lower flapper 23 as shown in FIG. At this time, no portion of the can 76 contacts the protruding end 110 of the projection 70. That is, the thin can 76
Are supported at three points of the opposing wall 106, the lower flapper 23 and a part of the product discharging device 20, and do not contact the projection 70. In this embodiment, a part of the thin can 76 is in contact with the opposing wall 106, and the contact portion is a projection 7 provided on the opposing wall 106.
0, and the height of the top of the thin can 76 is
Although the height exceeds the height of the protruding portion 110, the protruding portion 110 of the protrusion 70 does not contact the fine can 76 because the outer periphery of the can 76 has a large curvature and the height of the protrusion 70 is low.

At this time, the lower flapper 23 and the link A,
The positional relationship of B is the same as in the case of the thick can described above, with the link A positioned in the tangential direction of the swing trajectory of the lower flapper 23 with the swing center axis 58 of the lower flapper 23 as the center. Are located in the tangential direction of the swing trajectory of the link A about the swing center 64 of the link A. Therefore, the load of the can is blocked by the link A, and the link A is fixed by the link B, and the lower flapper 2
3 maintains a substantially horizontal posture, and the can does not fall.

At this time, the upper flapper 22 is in a vertical position.
It is in the moment and retreating. Here, the thick can and square pen
When selling bottles, the auxiliary support member 26 is
Pushed by a can, it is in the retracted position as shown in Fig. 5 (a).
However, when selling thin cans, the auxiliary support member 26
It becomes a protruding posture. In other words, small cans have a small diameter and

Since the diameter is substantially equal to the diameter of the thin can 77 as shown in FIG.
26 is biased by the spring 54 without contacting the thin cans 76 and 77.
To a horizontal position.

Subsequently, by inserting coins and selecting commodities,
When a predetermined signal is issued, the solenoid 27 functions to pull up the interlocking member 28. At this time, the hook 47 provided at the lower end of the interlocking member 28 raises the shaft 66 that is the center of swing of the link B. Then, link B and link A
Is broken, a force in the lateral direction (oscillation direction) acts on the link B by the force received from the link A, and the link B
The rear end side is further raised by the force. Then, the link A swings along with the link B, the inclination angle with respect to the lower flapper 23 changes, and the lower flapper 23 moves in the closing direction due to the load of the thin can. For this reason, the thin can 76 located at the lowermost position falls and the product is discharged.

Then, the interlocking member 28 is continuously pulled up by the solenoid 27, and the positional relationship between the shaft 48 interlocking with the interlocking member 28 and the guide groove 31 of the upper flapper 22 changes, and the upper flapper 22 swings about the axis 50. Move. That is, the upper flapper 22 protrudes as shown in FIG.

Also, at this time, since the leading end of the auxiliary support member 26 projects beyond the tip of the upper flapper 22 toward the opposed wall 106, the overall projection amount is located closer to the tip than in the case of the upper flapper 22 alone. I do.

Therefore, the leading end of the auxiliary support member 26 comes into contact with the second thin can 77 as shown in FIG. That is, the upper flapper 22 is substantially extended by the auxiliary support member 26 and comes into contact with the thin can 77 to prevent the thin can 77 from dropping.

Therefore, the lower flapper 23 has no load and returns to the horizontal position by the force of the spring 59. The link A is located in the tangential direction of the swing trajectory of the lower flapper 23,
Further, the link B is stabilized in the tangential direction of the swing trajectory of the link A about the swing center 64 of the link A. Then, when the discharge of the bottom product is confirmed, the solenoid 27 returns, and the upper flapper 22 returns. Then, the auxiliary support member 26 holding the second thin can 77
Loses a member to be attached and is inclined by the weight of the thin can 77. Then, the thin can 77 moves slightly zigzag, falls down on the lower flapper 23, and is supported by the lower flapper 23.

Next, the assembly structure of each member will be described. Each member of the lower flapper 23 is attached to the frame 21. That is, in the lower flapper 23, the shaft 58 is inserted into both the shaft hole 40 provided in the main body portion and the shaft hole 41 provided in the joining member 38,
It is swingably attached to the frame 21.
The distance between the shaft 58 for swinging the lower flapper 23 and the shaft 51 for swinging the auxiliary support member 26 is the same as in the previous embodiment.

Also in this embodiment, the lower flapper 23
The shaft 58 is inserted through the upper part, and the lower part is a free end. Also, a stopper not shown is provided,
The swing range of the lower flapper 23 is restricted. Here, in the previous embodiment, the swing range of the lower flapper 23 was in the range from vertical to substantially horizontal posture.
It can be swung until the free end is up. Further, in this embodiment, the lower flapper 23 is urged by an urging means including a spring 59 (FIG. 1) so as to be always in an open position. That is, the lower flapper 23 is
9 is always urged in the protruding direction.

In this embodiment, the lower flapper 23 is urged in the axial direction by the spring 140. That is, in the product discharging device 120 of the present embodiment, the spring 140 is inserted through the shaft 58 that swings the lower flapper 23. The mounting position of the spring 140 is, as shown in FIG. 12 to FIG. Part. Here, the support rod 117
Since the lower flapper 23 is integrally attached to the frame 21, the lower flapper 23 is pressed toward the other support rod 118 by the action of the spring 140. As described above, the shaft hole 4 at the center of the lower flapper 23 (plate-like portion 43)

Since the fixed member 125 is provided on the other support rod 118, the driving member 116 is constantly urged toward the fixed member 125 by the spring 140.

The drive side member 116 provided on the lower flapper 23 swings in accordance with the swing of the lower flapper 23. When the lower flapper 23 is in the most opened state, the drive side member 116 and the fixed side member 125 are rotated. Engage. More specifically, when the lower flapper 23 swings and the free end side is located about 5 to 10 degrees higher than the horizontal, the lower flapper 2
The positions of the three protrusions 138 provided on the three correspond to the positions of the three cutout holes 137 provided on the fixed-side member 125, and the drive-side member 116 and the fixed-side member 125 engage with each other.

The tip of the link A is engaged with the guide groove 45 of the lower flapper 23 via the shaft 60. That is, the shaft 60 is inserted into the round holes 130 of the belt-shaped members 61 a and 61 b of the link A, and both ends of the shaft 60 are engaged with the guide grooves 45 of the lower flapper 23. Therefore link A
Is slidable along the guide groove 45 and can also rotate via the shaft 60. A shaft 132 is inserted into a long hole 131 provided on the other end side of the link A, and the shaft 132 is further connected to the long hole 122 at the end (lower part of the drawing) of the support rods 117 and 118 and a part 21 of the frame. Is inserted through a long hole 133 provided in the hole. The other end of the link A is connected to the support rod 117, 1 via the shaft 132 as described above.
18, it can swing about the shaft 132. Further, the support rods 117 and 118 on which the shaft 132 is supported and the frame 21 are provided with the elongated holes 12.
2, 133 are provided, so that the link A
Linear movement is possible only in the range of 2,133.

The tip of the link B is connected to the hidden plate 62 of the link A.
Is rotatably attached to the cut-back portion 135 provided at the bottom. That is, the pin 1 provided at the tip of the link B
27 engages with a hole 136 provided in the cut-back portion 135. On the other hand, a shaft 128 is inserted into the rear end side of the link B, and is engaged with the elongated hole 121 of the intermediate portion between the support rods 117 and 118. The long hole 121 is arcuate, slightly curved, and extends substantially vertically. Therefore, the rear end of link B
It moves substantially vertically along the elongated hole 121.

The shaft 128 inserted into the link B has
The lower end of the hook 47 of the interlocking member 28 can be engaged as shown in FIGS. The relationship between the hook 47 and the shaft 128 is the same as in the previous embodiment.
28 is moved upward by being hooked on the hook,
8 can rise alone.

The positional relationship between the lower flapper 23 and the links A and B is as shown in FIG. 17 (a). Around the shaft 58, the lower flapper 23
The link A is located substantially in the tangential direction of the swing trajectory. More precisely, the link A is slightly deviated from the tangential direction of the swing trajectory of the lower flapper 23, and the shaft 132 serving as the swing center is
, The other end is at a position where a rotational force is obtained in a direction approaching the frame 21 (counterclockwise in the figure). However, as described above, the deviation of the swing trajectory of the lower flapper 23 of the link A from the tangential direction is small, and the rotational force applied to the link A is extremely small. The position is the end of the guide groove 45, and the tip of the link A stops using the end of the guide groove 45 as a stopper. On the other hand, the other end of the link A is connected to the frame 21 via the shaft 132. Therefore, a triangle closed by the lower flapper 23, the link A, and the frame 21 is formed, and the force received from the lower flapper 23 mainly acts on the link A as an axial force. Therefore, most of the force that the lower flapper 23 receives from the product acts in the axial direction of the link A,
The force that the lower flapper 23 receives from the product is supported by the link A. Further, a rotational force slightly generated in the link A is supported by the link B.

That is, at this time, the lower end of the link B is located in the straight portion 121b on the lower end side of the elongated hole 121. At this time, the attitude of the link B is slightly deviated from the tangent of the swing trajectory of the link A, and the link B is
When the link A rotates in the closing direction (counterclockwise) around the center 32, the lower end of the link B is at a position where a force is received in the downward direction. In the present embodiment, when the lower flapper 23 is in a substantially horizontal posture, the load of the lower flapper 23 is mainly supported only by the link A, and the link B bears a slightly generated component in the rotation direction of the link A. Therefore, the link A does not swing depending on the weight of the product on the lower flapper 23, and holds the lower flapper 23 in a substantially horizontal posture.

When the link A is forcibly moved in the closing direction, the lower end of the link B moves downward, and
The link B bears the force received from the link A while hitting the end of the linear portion 121b on the lower end side of the link. Therefore, also in the present embodiment, the lower flapper 23 is operated by operating the link A.
Cannot be lowered.

On the other hand, when the rear end of the link B rises, the link B exceeds the tangential direction of the swing trajectory of the link A. Therefore, when a force is applied from the link A in the closing direction, the rear end of the link B leaves the linear portion 121b of the elongated hole 121 and moves to the middle circular arc portion 121c. Therefore, when the rear end of the link B rises, the link B cannot prevent the swing of the link A. When the rear end of the link B rises, the link A naturally moves in the closing direction due to the above-described component force in the rotation direction of the link A. Beyond the tangential direction of the swing locus of That is, in the present embodiment, the link B functions as a stopper for preventing the rotation of the link A. However, when the rear end side of the link B rises, the link B is in a state where the stopper comes off. Therefore, the lower flapper 23
A is received in the closing direction by a force for lowering the pressure (a force for rotating the lower flapper 23 clockwise), and the link A
Of the lower flapper 2 moves along the guide groove 45.
3 tilts and moves in the storage direction. That is, the movement of the link A causes the link A to be unable to prevent the swing of the lower flapper 23. Therefore, as a result, when the rear end side of the link B is raised, the swing prevention of the lower flapper 23 is released.

The above-described vending machine product dispensing apparatus 120
Is attached to the lower part of the product passage 2 of the vending machine as shown in FIGS. Further, a wall-side projection 70 is provided on the opposite wall 106 of the product passage 2 at a position corresponding to the highest height of the upper flapper 22 when the upper flapper 22 protrudes as shown in the figure. The cross-sectional shape of the wall-side projection 70 is the same as that of the previous embodiment, and is a substantially right triangle. The inclination angle θ of the inclined wall 112 is 15 ° or less, and more preferably 12 ° or less.

Also, the product dispensing apparatus 120 of this embodiment is
Regarding the positional relationship and the like of each part of the facing wall 106 of the article passage,

The shortest distance Wd between the protrusion 26 and the tip 110 of the wall-side projection 70 is:
It is 65% or less of the width W of the product passage.

Further, the position and height of the protruding end portion 110 of the wall-side projection 70 and the positional relationship of the lower flapper (main product support member) 23 are as follows. Sometimes a part of the cylinder is a wall-side projection 7
70% of the width W of the product passage 2
When the cylinder is supported by the lower flapper 23, no part of the cylinder is in contact with the protruding end 110 of the wall-side projection 70.

Next, the overall operation of the commodity dispensing apparatus 120 of the vending machine according to the present embodiment will be described. Figures 17 and 18
5 shows a state in which a thin can is discharged by the product discharging device 120 of the vending machine of the present embodiment. 12 to 15
Fig. 12 shows the product dispensing apparatus 120 observed from the back side at this time. Fig. 12 shows a state corresponding to Fig. 17A, and Fig. 13 corresponds to Fig. 17B. FIG. 14 is a timing diagram corresponding to FIG. 18A, and FIG. 15 is a timing diagram corresponding to FIG. 18B.

FIGS. 17 and 18 show the long holes provided in the lower part of FIG. 17 and FIG.
3 shows the positional relationship between the long holes 122 and 133 provided in the shaft A and the shaft 132 that supports the rear end side of the link A. The drawing drawn further below illustrates the relationship between the drive side member 116 provided on the lower flapper 23 side and the fixed side member 125 provided on the support rod 118. That is, the figure shows the operation of the temporary fixing means 115.

When used for discharging cans by the product discharging apparatus 120 of this embodiment, the lowermost can 76 is supported by the lower flapper 23 as shown in FIG. At this time, the lower flapper 23 is located at a position slightly lower than the upper limit of the swingable range. That is, in the present embodiment, the lower end of the lower flapper 23 is 5 ° to 10 °
The lower flapper 23 is inclined so that the free end side thereof is lower than the swing shaft 58 when the can 76 is supported. At this time, the relationship between the lower flapper 23 and the link A is such that the link A is located substantially in the tangential direction of the swing trajectory of the lower flapper 23 about the swing center axis 58 of the lower flapper 23. More precisely, the link A is slightly deviated from the tangential direction of the swing trajectory of the lower flapper 23, and the shaft 13 serving as the swing center is
2, the other end is located at a position where a rotational force is obtained in a direction in which the other end approaches (counterclockwise in the figure). The position is the end of the guide groove 45, and the end of the link A stops using the end of the guide groove 45 as a stopper. On the other hand, the other end of the link A is connected to the frame 21 via the shaft 132. Accordingly, a triangle closed by the lower flapper 23, the link A, and the frame 21 is formed, and the load of the lower flapper 23 is mostly countered by the axial force of the link A, and the rotational force of the link A slightly further occurs. Is against the link B, the link A does not swing, and the lower flapper 2
3 is held in a substantially horizontal posture.

The axial load of the link A at this time is such that the upper end edge of the long hole 131 of the link A pushes the shaft 132 as shown in the upper part of FIG. 117, 118 and the long holes 122, 133 of the frame 21.
Is pressed by the frame 21 to be supported by the frame 21.

At this time, the temporary fixing means 115 is not engaged as shown in the figure. The lower end of the link B is located at the lower end of the elongated hole 121.

At this time, the upper flapper 22 is in the vertical position and is retracted. As described in the previous embodiment, the thin can has a small diameter, and the distance between the position of the shaft 58 for swinging the lower flapper 23 and the shaft 51 for swinging the auxiliary support member 26 is as follows. Since the diameter of the thin can 77 is substantially equal to that of the thin can 77 as shown in FIG.
, And is urged by the spring 54 to assume a horizontal posture.

Subsequently, by inserting coins and selecting commodities,
When a predetermined signal is issued, the solenoid 27 functions to pull up the interlocking member 28. At this time, the hook 47 provided at the lower end of the interlocking member 28 pulls up the shaft 128 as the swing center of the link B. Then, the end of the link B rises and pulls the link A to the closing side. Then link A
Is separated from the end of the guide groove 45 and further deviates from the tangential direction of the swing trajectory of the lower flapper 23. Therefore, the lower flapper 23 is inclined by the weight of the can 76, and the tip of the link A slides along the guide groove 45, whereby the inclination of the lower flapper 23 proceeds, and the lower flapper 23 is inclined.
Tilts and moves in the storage direction.

On the other hand, a force in the swing direction acts on the link B by the force received from the link A, and the rear end side of the link B further rises by the force. That is, also in the present embodiment, the hook 47 of the interlocking member 28 merely hooks the shaft 128, and the shaft 128 can move upward by leaving the hook 47. Is
It rises faster than the rise of the interlocking member 28. Then, the link A swings along with the link B, and the pin 60 on the distal end side of the link A moves along the guide groove 45 of the lower flapper 23, and the inclination angle with respect to the lower flapper 23 changes. Therefore, the lower flapper 23 is pushed open by the load of the thin can 76. Therefore, the thin can 76 located at the lowermost position falls, and the product is discharged as shown in FIG.

Then, the interlocking member 28 is continuously pulled up by the solenoid 27, and the positional relationship between the shaft 48 interlocking with the interlocking member 28 and the guide groove 31 of the upper flapper 22 changes. Move. That is, as shown in FIG.
Protrudes. Also in this example, the diameter of the thin can was small,
Further, the distance between the position of the shaft 58 for swinging the lower flapper 23 and the shaft 51 for swinging the auxiliary support member 26 is substantially equal to the diameter of the thin can 77 as shown in FIG. Is in contact with the thin cans 76 and 77 and is urged by the spring 54 to be in a horizontal position. Therefore, the upper flapper 22 swings in a state where the auxiliary support member 26 is in the horizontal posture, and the front end portion engages with the front end portion of the auxiliary support member 26. Therefore, as shown in FIG. 7B, the auxiliary support member 26 is in a state where the front end side is held by the upper flapper 22 and does not swing. At this time, the leading end of the auxiliary support member 26 is located closer to the opposite wall 106 than the tip of the upper flapper 22.
The upper flapper 22 is located on the tip side as compared with the case where the upper flapper 22 is used alone.

For this reason, the leading end of the auxiliary support member 26 comes into contact with the second thin can 77 as shown in FIG. That is, the upper flapper 22 is substantially extended by the auxiliary support member 26 and comes into contact with the thin can 77 to prevent the thin can 77 from dropping.

Therefore, the lower flapper 23 is not loaded and returns to the horizontal position by the force of the spring 59. The link A is located in the tangential direction of the swing trajectory of the lower flapper 23,
Further, the link B is stabilized in the tangential direction of the swing trajectory of the link A about the swing center 64 of the link A. Then, when the discharge of the bottom product is confirmed, the solenoid 27 returns, and the upper flapper 22 returns. Then, the auxiliary support member 26 holding the second thin can 77
Loses a member to be attached and is inclined by the weight of the thin can 77. Then, the thin can 77 falls to the lower flapper 23 and is supported by the lower flapper 23.

As described above, since the can 77 is held by the upper flapper 22 and the lower flapper 23 has no load, the lower flapper 23 returns to the upper end by the force of the spring 59. That is, the product discharging device 120 of the present embodiment of the present embodiment
Then, since the lower flapper 23 can swing until the free end side is higher than the swing shaft 58 by about 5 to 10 °, the lower flapper 23 is moved by the force of the spring 59 as shown in FIG.
As described above, until the free end side is higher than the swing shaft 58. At this time, in the product dispensing apparatus 120 of the present embodiment, the slots A, the support rods 117, 118, and the like have elongated holes 131, 122,
133 are provided, and the long holes 131, 122, 1
Since the link A and the frame 21 are connected via the shaft 132 inserted into the shaft 33, the lower flapper 23 operates as if jumping up to the upper end. More specifically, when the lower flapper 23 is at the highest position,
As shown in the upper part of FIG. 18C, the pulling force generated in the link A is such that the lower end edge of the long hole 131 of the link A pulls the shaft 132, and the shaft 132 further moves the support rods 117, 118 and the frame 21. The upper ends of the elongated holes 122 and 133 are pulled and supported by the frame 21. Accordingly, the link A substantially moves in the axial direction, moves so as to extend, and quickly brings the lower flapper 23 to the upper end.

3 oscillates again and the drive side member 116 and the fixed side member 125
Engage. By these series of operations, the lower flapper 23
Is consumed, and the lower flapper 23 temporarily stops.

When the discharge of the lowermost product is confirmed, the solenoid 27 returns and the upper flapper 22 returns. As a result, the can 76 falls on the lower flapper 23. Then, the lower flapper 23 swings due to the weight applied to the lower flapper 23, and the temporary fixing means 115 is disengaged against the force of the spring 140. Here, since the drive side member 116 and the fixed side member 125 constituting the temporary fixing means 115 are both made of resin, the temporary fixing means 115 can be smoothly disengaged. As a result, as described above, the free end side of the lower flapper 23 is inclined so as to be slightly lower than the swing shaft 58, and the swing trajectory of the lower flapper 23 about the swing shaft 58 of the lower flapper 23. Since the link A is positioned in the tangential direction of the can, it bears the weight of the can and maintains a substantially horizontal posture.

When the upper flapper 22 returns, the can 76
In the present embodiment, since the projections 70 and 71 are provided on both the product discharging device 120 and the opposed wall 106, the can 77 has a slightly zigzag shape. And is placed on the lower flapper 23.
