Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vending machine for large bottles such as 500ml, 1, 1.8, etc.

Prior Art Most conventional vending machines dispense small bottles. If this small-bottle vending machine is modified to use large-sized bottles, the impact at the time of dispensing is so great that the large-sized bottles will be destroyed.

Therefore, Japanese Patent Application No. 76,200/1980 has previously proposed a product delivery device that can support and guide the bottle to the vicinity of the guide chute to the product removal port to weaken the impact during delivery. In this device, as shown in FIG. 10a, products 51a, 51b, etc. stacked in series on a stocker 50 are supported by a support lever 52 and a side wall 53 of the stocker 50. As shown in Figure 10 b, support lever 5
2 begins to rotate downward about the shaft 55 together with the delivery lever 54, and all the products in the stocker 50 gradually lower. Next, the support lever 52 is raised to the first position.
As shown in Figure 0c, the lowest product 51a and the next product 5
1b is held together with the products above it, and the delivered product 51a is sent out by the delivery lever 54 while weakening the impact.

Problem to be solved by the invention In the above configuration, the lowest product 5 to be dispensed
1a is lowered while being supported by the support lever 52 and the side wall 53 with the full load of the products above being applied, so there is a risk that the surface of the lowest product 51a to be dispensed may be scratched. If the film is covered with a film wrapper, this may cause the film wrapper to tear. This problem becomes more serious as the products handled are large bottles and the total load applied to the lowest product is greater.

The present invention solves the above-mentioned conventional problem.When starting dispensing, the second or higher large bottles from the bottom are held, and only the lowest large bottle is dispensed while weakening the impact. To provide a large bottle vending machine that smoothly separates and holds only the lowest large bottle among the second or more large bottles held. It is something.

Means for Solving the Problems A stocker with an open bottom surface provided to store large bottles stacked vertically in a line; a guide chute to a product outlet provided below the stocker; One end of each is rotatably attached to the lower part of the stocker, and supports the lowermost large bottle and the second or higher large bottles from the bottom between it and the stocker side plate, and prevents them from interfering with each other. The rolling shelf and stop shelf are moved vertically through a drive shaft that is rotated once based on a product selection signal, and a cam roller that is fixed to the drive shaft and abuts on the circumferential surface of each cam. In a vending machine equipped with a rotating first cam and a second cam, the rolling shelf has a distal end positioned at the center within the stocker when on standby, supporting a large bottle at the lowermost end, and a proximal end positioned at the center of the stocker. is configured such that the stop shelf is pivoted at a position near one side plate of the stocker, and the base end of the stop shelf is pivoted at a position near the other side plate of the stocker, and the distal end thereof approaches the one side plate of the stocker. The distal end is located above the pivot axis of the rolling shelf when on standby, and the distal end is located above the stop shelf inside the other side plate of the stocker, and the tip part is arranged above the stop shelf so as to connect to the inner passage of the stocker. A guide plate is provided to support the second large bottle from the bottom with the tip of the stop shelf that has moved upward, and the second large bottle from the bottom is supported by the tip of the stop shelf that has moved upward. The shape of the cam peripheral surface of the cam and the second cam is changed so that the rolling shelf and the stop shelf alternately rotate in the vertical direction, and the rolling shelf, which supports the large bottle at the bottom end, supports the large bottle at the bottom end when the rolling shelf supports the large bottle at the bottom end. Releases its support at a nearby position on the guide chute, then the rolling shelf that moves up receives the large bottle on the stop shelf that moves down, and the stop shelf that moves up after passing the large bottle to the rolling shelf The present invention is characterized in that it is configured to receive and support the second or more large bottles from the bottom of the large bottles supported by this rolling shelf from a rolling shelf that moves downward.

Effect With the above configuration, when a product selection signal is received, the drive shaft rotates and the first cam and the second cam make one revolution, and the first cam roller and the second cam roller interlocked with this rotate the first cam roller and the second cam roller. The rolling shelf that supported the large bottle at the bottom moves downward, and dispenses the large bottle at the bottom at a position near the guide chute with a weakened impact. After receiving the large bottle from the stop shelf that moves downward while supporting the second or larger large bottle, and delivering the large bottle to the rolling shelf, the stop shelf moves up and receives this rolling shelf from the rolling shelf that moves downward. The elf operates to receive and support the second or higher large bottle from the bottom of the large bottles supported by the elf. The guide plate prevents only the large bottles from hitting the upwardly moving stopshelf, and as a result, the second or higher large bottles from the bottom of the large bottles are smoothly moved against the upwardly moving stopshelf. Along with the handover, the rolling shelf itself returns to its initial position, supporting only the bottom large bottle.

This is an interlocking gear that meshes with gears 9 and 30. Therefore, the drive shaft 7 and the driven shaft 9 rotate integrally. 33 is an operation stop cam having a protrusion 33a, and is fixed to the drive shaft 7. 3
4 is a limit switch whose main body is screwed to the front plate 3a and whose sensing lever 34a faces the projection 33a, and when the projection 33a hits the sensing lever 34a, the operation of the motor 27 is stopped.

The guide plate 40 is attached to the other side plate 3 at a position slightly above the stop shelf 21 in the stocker 3.
The large bottles 5 on the stop shelf 21 are aligned toward one side plate 3b, and when dispensing, the large bottles 5 are lowered and The lowermost large bottle 5 of the aligned bottles is located at the lower end position of the guide plate 40 and the other side plate 3
When the stop shelf 21 approaches the direction c, the stop shelf 21 is brought into a state where it can avoid engagement with the support plate part 21b.

In Figures 1 and 2, 41 is a large bottle 5.
42 is a guide chute for the large bottle 5, 43
is an outer gate disposed at the outlet 42, and 45 is a guide plate disposed along the rear plate 3d inside the stocker 3.

The operation of the above configuration will be explained based on FIGS. 5 to 9. In Figure 9, A is rolling shield 17
, and b indicate the operations of the stop shield 21, respectively. First, the state shown in FIG. 5 shows the initial state before the large bottle 5 is dispensed.
and the side plate 3c of the stocker 3 and are supported. Further, the second large bottle 5 from the bottom is supported against the stop shelf 21 and the guide plate 40.

When a predetermined coin is inserted into the coin slot and the product selection button is pressed, the product selection signal activates the motor 27 of the stocker 3 containing the selected large bottle 5, and the drive gear 28 moves in the direction of the arrow. The drive shaft 7 is rotated in the direction of arrow A through the first driven gear 29, and the first driven gear 29, the interlocking gear 32, the interlocking shaft 31, the interlocking gear 32, and the second driven gear The driven shaft 9 is also rotated in the direction of arrow B via 30. As a result, the first
Both second cams 14, 22 are also rotated in the direction of arrow B.

When both cams 14 and 22 rotate by 66 degrees, the first cam roller 52 hits the troughs 15a of the fourteen cam surfaces 15 of the first cam, as shown in FIG. 6, and the rotating plate 51 rotates in the direction of arrow C. As a result, the rolling shelf 17 also moves through the transmission cam roller 18 as shown by the arrow E.
The distance α between the supporting plate portion 17b and the side plate 3c of the rolling shelf 17 is larger than that of the large bottle 5.
The large bottle 5 at the bottom falls from inside the stocker 3 into the chute 41 and is discharged to the outlet 42. In this case, the large bottle 5 does not suddenly fall from the stocker 3, but is gradually lowered while being supported by the rolling shelf 17 and then dropped onto the chute 41. The impact can be suppressed to a minimum, and the large bottle 5 will not be destroyed. Note that during this time, the second cam roller 24
Since the stopper elf 21 continues to contact the large diameter portion 23a of the cam surface 23 of and supports.

Next, when both cams 14 and 22 further rotate in the direction of arrow B, the rotating plate 51 is rotated in the direction of arrow D by the cam surface 15 via the first cam roller 52, and the transmission cam roller 18 The rolling shelving 17 rotates in the direction of arrow F, and when both cams 14 and 22 have rotated 163 degrees, the support plate portion 17 of the rolling shelving 17 rotates as shown in FIG.
b rises to the highest level and maintains that state for a while.

Also, as described above, before both cams 14 and 22 rotate 163 degrees, the second cam roller 24
begins to move to the small diameter portion 23b of the cam surface 23, and the stop shelf 21 begins to rotate in the direction of arrow C. As a result, the large bottle 5 on the shelf 21 also descends.

Next, as both cams 14 and 22 further rotate, the lowermost large bottle 5 supported by the stop shelf 21 rotating in the direction of arrow C moves upward through the space in the center of the stop shelf 21. As shown in FIG. 8, both cams 14 and 22 hit the support plate portion 17b of the rolling shelf 17.
At the point of rotation of 223 degrees, the large bottle 5 is transferred from the stop shelf 21 to the rolling shelf 17.

Next, when both the cams 14 and 22 have rotated 314 degrees, the stop shelf 21 rotates in the D direction, avoiding engagement with the large bottle 5 at the lowermost end of the guide plate 40 and starting from below. When the second large bottle 5 is supported and both cams 14 and 22 have further rotated 338 degrees, the rolling shelf 17 returns to the original state shown in FIG. 5 and only supports the lowermost large bottle 5. be in a state of support.

Next, when both cams 14 and 22 rotate 360 degrees, the protrusion 33a of the operation stop cam 33 hits the sensing lever 34a of the limit switch 34, and the operation of the motor 27 is stopped, as shown in FIGS. 3 and 5. Returns to original standby state.

Effects of the Invention As described above, according to the large bottle vending machine of the present invention, there is a base at the bottom of the stocker, the tip of which is positioned at the center of the stocker when on standby to support the lowermost large bottle. A rolling shelf whose end is pivoted near one side plate of the stocker, and a base end pivoted near the other side plate of the stocker and whose distal end approaches the one side plate of the stocker. A stop shelf is provided, the tip of which is positioned above the pivot axis of the rolling shelf when on standby, and the large bottles stacked vertically in a line inside the stocker are dispensed. When doing so, first the large bottle at the bottom is supported by a rolling shelf and is gradually lowered to approach the guide chute, and then dropped onto the chute, so the impact during the fall is minimized. It is something that can be controlled. Therefore, even large bottles that are relatively easily destroyed can be dispensed smoothly without being destroyed. At this time, the entire load of the large bottles in the stocker is not applied to the lowermost large bottle to be dispensed, so there is no risk of scratching the surface of the lowermost large bottle. Moreover, the lowermost large bottle held by the stop shelf can be smoothly transferred to the rolling shelf by a series of vertical movements of the rolling shelf and the stop shelf as follows. The lowermost large bottle of the large bottles supported by the guide plate and the tip of the stop-shelf is now wider than the large bottle due to the downward movement of the stop-shelf. When the bottle is exhausted, the large bottle at the bottom before dispensing falls into the wide lower passage where the internal passage is not restricted by the guide plate.
This fallen large bottle is rotated upward and is supported by the tip of the waiting rolling shelf and the other side plate of the stocker. The height difference between shaped bottles can be reduced. Further, after the large bottle is transferred to the rolling shelf, the tip of the stop shelf passes between the large bottle supported by the rolling shelf and the one side plate of the stocker, moves upward, and moves upward to the guide plate. Since it is possible to support the large bottle above the bottom large bottle supported by the rolling shelf, that is, the second large bottle from the bottom, The large bottles stacked on top can be smoothly transferred toward the lower end of the stocker without giving a large impact, and there is no risk of accidental destruction of the large bottles.
