Description

[Detailed Description of the Invention] The present invention relates to a vending machine that stacks products in a line and stores them in a stocker, and particularly to a vending machine that handles large plates as products.

Conventionally, in this type of vending machine that handles bottled products, the product delivery device has been constructed as disclosed in Japanese Patent Application Laid-open No. 7620/1983.

FIG. 12 shows the delivery process of this conventional product delivery device.

When not dispensing, the stocker 50 as shown in Fig. 12a
Products 51a, 51b stacked in series...
is supported by the support lever 52 and the side wall 53 of the stocker 50, and when dispensing is started, the tip of the dispensing lever 54 begins to rotate downward around the shaft 55 as shown in FIG. All the products in the stack gradually begin to fall, and then the support lever 52 stands up, restricting the lowering of the product 51b next to the lowest product 51a and the products above it, as shown in FIG. 12C. Then press the delivery lever 5 again.
4 is opened and the product 51a is gradually dispensed.

In this way, the impact when the dispensed bottle product arrives at the product outlet can be weakened, but the delivery lever 54
Since the product 51b following the delivered product 51a is prevented from falling by the support lever 52, which is pivoted from the same side as the product 51a, there is a drawback that the product in the lowest bottle is likely to be damaged.

In other words, during the period when the lowest product 51a is passing in front of the support lever 52 as shown in FIG. 12 after the start of dispensing, the second product 51b from the bottom cannot be supported by the support lever 52. Since the product 51a is supported by the side wall 53 and the delivery lever 54 with the full load of the second product 51b and the products above it being applied to the product 51a for a long period of time, the product 51a may be damaged.

This drawback can cause the film packaging to tear if the surface of the bottled product is covered with a film packaging, and this is especially true if the product handled is a large bottle and the total load applied to the lowest product is large. The problem becomes more serious.

The purpose of the present invention is to provide a large bottle vending machine that supports the next product at the bottom at an early stage after the start of dispensing and can perform dispensing without applying a large load to the product at the bottom. shall be.

44 is an inner gate for heat insulation,
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 FIG. 9.

In FIG. 9, ``A'' indicates the operation of the rolling shelf 17, and ``A'' indicates the operation of the stop shelf 21, respectively.

First, the state shown in FIG. 6 shows the state before the large board 5 is rolled out, and the large board 5 at the lowest end is on the rolling shelf 17.
It is prevented from falling by hitting the support plate portion 17b of the stocker 3 and one side plate 3b of the stocker 3.

Further, in this state, the drive bin 26 is located at the starting end within the elongated hole 25.

When a specified coin is inserted into the coin slot and the product sorting button is pressed, the motor 27 of the stocker 3 containing the sorted large plates 5 is activated. Rotate in direction A.

Then, the pin 29 of the disk 28 rises, the crankshaft 30 moves in the direction of arrow C, rotates the drive 1llith7 in the direction of arrow E via the notched gear 32, and further rotates the first
The driven shaft 9 also rotates integrally with the drive shaft 7 in the same direction E at the same speed via the large gear 35, small gear 38, interlocking shaft 19, small gear 39, and second canine gear 36.

As a result, both first cams 14 also rotate in the same direction E, and both first cams 14 rotate in the same direction E.
When the cam 14 has rotated 15 degrees, both first cam rollers 1
8 passes point b of the cam surface 15, and the rolling shelf 1
7 begins to descend.

Therefore, the large plate 5 at the lowermost end also descends. both 1st cam 1
4 rotates by 55 degrees, the drive pin 26 hits the end of the elongated hole 25, resulting in the state shown in FIG.

In this state, the lowermost large plate 5 is in contact with the support plate portion 17b of the rolling shelf 17 and the other side plate 3e of the stocker 3, and does not fall.

Further, a distance a is formed between the lowermost large plate 5 and one side plate 3b of the stocker 3, which is sufficient for the support plate portion 21b of the stop shelf 21 to pass upward.

Next, when both first cams 14 further rotate in the direction of arrow E, both second cams 22 also rotate in the same direction E by the drive pin 26. When both first forces l and 14 have rotated 62 degrees, both second cams 22 rotate by 62 degrees. The second cam roller 24 rides up from above the small diameter part 23b to the large diameter part 23a of both second cams 22, thereby causing the stop shelf 21 to rotate in the direction of arrow G by 19 times on the interlocking shaft, and to move the second cam from the bottom. The user takes a posture of waiting for the large board 5.

Next, when both the first forces 1 and 14 further rotate in the direction of the arrow E, the support 'I'J plate part 17b of the rolling shelf 17
The distance β between the side plate 3c and the other side plate 3c of the stocker 3 gradually increases, and each large plate 5 slowly descends.

And the second large board 5 from the bottom is the stop shelf 21
By hitting the support plate portion 21b and the guide plate 40, the second large plate from the bottom is prevented from descending any further.

After this, as the interval β increases, only the lowermost large plate 5 descends, and when the interval β becomes larger than the outer diameter of the large plate 5, the lowermost large plate 5 moves to the stocker. 3
It falls from inside into the chute 41 and is dispensed to the outlet 42.

In this case, the large plate 5 does not suddenly fall from the stocker 3, but is gradually lowered to the lower end of the stocker 3 while being supported by the rolling shelf 17, and then is dropped onto the chute 41. By keeping the chute 41 close to the stocker 3, the impact when it falls can be minimized, and the large plate 5 will not be damaged.

Next, when both first cams 14 have rotated by <87 degrees as shown in FIG.
Drive shaft 7, driven shaft 9, both first cams 14, and both second cams 2
2 in the direction of arrow F.

Then, the rolling shelf 17 begins to rotate in the direction of the arrow I] force, and both first forces! , 14 return to 72 degrees, that is, 15 degrees to the initial state, both first cam rollers 18 pass through point b of the cam surface 15.

Therefore, the rolling shelf 17 returns to its original state as shown in FIG.
It is stopped with a slight gap between the bottom and the bottom.

Also, at this time, both second cams 22 do not rotate until the drive bin 26 rotates in the direction of arrow F and hits the starting end of the elongated hole 25, so the second cams 22 lag behind both first cams 14 by that amount and rotate in the direction of arrow F. It will rotate in the F direction.

Therefore, the stop shelf 21 is in the state shown in FIG. 8, supporting the large plate 5 second from the bottom, that is, the lowest in this state.

Next, when both first cams 14 further rotate in the direction of arrow F,
Both second cam rollers 24 descend from the large diameter portion 23a of the cam surface 23 to the small diameter portion 23b, the support plate portion 21b of the stop shelf 21 descends, and the bottom surface of the large plate 5 moves to the support plate portion 17b of the rolling shelf 17. The support plate portion 21b of the stop shelf 21 is separated from the large plate 5 and returns to the state shown in FIG.

In the above embodiment, the second cam 22 is rotated by the first cam 14 via the drive pin 26 and the elongated hole 25, but in addition to this, as shown in FIG. 25 and two drive pins 30 on the first cam 14.
．． 31 may be provided protrudingly.

Depending on this configuration, the first cam 1 can be changed from the state shown in FIG.
4 is rotated in the direction of arrow E, one of the drive pins 50 hits the side surface of the second cam 22 after a while, causing the second cam 22 to rotate in the direction of arrow E.

Further, when the first cam 14 is rotated in the direction of the arrow F with the lowermost large plate 5 pushed out (see FIG. 8), the other drive pin 51 hits the side of the second cam 22 after a while. This second cam 22 is rotated in the direction of arrow E.

As described above, the large plate vending machine of the present invention has a rolling shelf that supports the bottom surface of the lowermost large plate and whose base end is pivoted near one side plate of the stocker. a stop shelf is provided that is disposed close to the one side plate of the stocker and rotates upwardly within the stocker in conjunction with the downward rotation of the rolling shelf; The base end of the side plate is pivoted at a position near the other side plate of the stocker, and the support plate is attached to the rolling shelf. Waist rolling Since the large board being dispensed while being supported by the shelf passes between the plates on both sides of the stop shelf, the second large board from the bottom is moved quickly after the start of dispensing without waiting for the lowest large board to pass. Large plates can be supported by a stop shelf, and the period of the large load acting on the large plate during dispensing (the total load of the remaining large plates) is shortened compared to the conventional method. It can improve the situation where the board gets scratched.

Therefore, even if the product is a large plate whose surface is wrapped in a film package, it can be dispensed without tearing the film package.
