Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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 bottles as products.

BACKGROUND ART 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. 76200/1983. FIG. 11 shows the delivery process of this conventional product delivery device. At the time of non-payout, the first
The products 51a, 51b... stacked in series on the stocker 50 as shown in Figure 1a are supported by the support lever 52 and the side wall 53 of the stocker 50, and when dispensing starts, they are delivered as shown in Figure 11b. The tip of the lever 54 begins to rotate downward around the shaft 55, and all the products inside the stocker 50 begin to gradually fall, and then the support lever 52 stands up, as shown in Fig. 11c.
As shown in the figure, the product 51b next to the lowest product 51a and the products above this are restricted from descending, and the delivery lever 54 is further opened to release the product 51a.
will be paid out gradually.

Problems to be Solved by the Invention With such a conventional configuration, it is possible to weaken the impact when the dispensed bottle product arrives at the product outlet, but the support lever pivoted from the same side as the delivery lever 54 52 prevents the product 51b following the delivered product 51a from falling, so there is a drawback that the product in the lowest bottle is likely to be damaged.

That is, during the period when the lowest product 51a is passing in front of the support lever 52 as shown in FIG. 11b after the start of dispensing, the second product 51b from the bottom cannot be supported by the support lever 52. Product 51a has a second product 51 over a long period of time.
Since the product 51a is supported by the side wall 53 and the delivery lever 54 with the full load of the product 51a and products above it being applied, the product 51a is 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.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vending machine for large bottles that can support the next product at the bottom at an early stage after the start of dispensing and perform dispensing without applying a large load to the product at the bottom. shall be.

Means for Solving the Problems The large bottle vending machine of the present invention includes a stocker with an open bottom that is surrounded by a front plate, a rear plate, and both side plates and stores large bottles stacked in a row.

The operation of the above configuration will be explained based on FIG. 9.
In FIG. 9, A shows the operation of the rolling shelf 17, and B shows the operation of the stop shelf 21. In the following explanation, the lowermost large bottle 5 will be described as 5A, and the second and third bottles from the bottom will be described as 5B, 5C, and so on. First, before dispensing the product, as shown in FIG. 6, the bottom large bottle 5A hits the support plate 17b of the rolling shelf 17 and one side plate 3b of the stocker 3 to prevent it from falling. There is. Further, in this state, the drive pin 26 is located at the starting end of the elongated hole 25. When dispensing products, the drive motor 2
7 operates to rotate the disc 28 in the direction of arrow A as shown in FIG. Then pin 29 of disk 28
rises, the crankshaft 30 moves in the direction of arrow C, rotates the drive shaft 7 in the direction of arrow E via the notched gear 32, and then rotates the first large gear 35, small gear 38, interlocking shaft 19, and small gear. 39 and the second large gear 36, the driven shaft 9 also rotates integrally with the drive shaft 7 in the same direction E at the same speed. As a result, both first cams 14 also rotate in the same direction E, and both first cams 14
After rotating by 15 degrees, both first cam rollers 18 pass point b on the cam surface 15, and the rolling shelf 1
7 begins to descend, and the large bottles 5A, 5B, etc. on top of the rolling shelf 17 begin to descend.

When both first cams 14 rotate by 55 degrees, the drive pin 2
6 corresponds to the end of the elongated hole 25, resulting in the state shown in FIG. In this state, the lowermost large bottle 5A is in contact with the support plate portion 17b of the rolling shelf 17 and the other side plate 3c of the stocker 3, and has not fallen yet at this stage. However, at this time, an interval α is formed between the lowermost large bottle 5A 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, and when both first cams 14 have rotated 62 degrees, both The second cam roller 24 rides on the large diameter portion 23a from above the small diameter portion 23b of both second cams 22, and as a result, the stop shelf 21 rotates in the direction of arrow G around the interlocking shaft 19, and The person waits for the second large bottle 5B.

Next, as both first cams 14 further rotate in the direction of arrow E, the distance β between the support plate portion 17b of the rolling shelf 17 and the other side plate 3c of the stocker 3 gradually increases. Each large bottle 5A,
5B...is slowly descending. Then, the second large bottle 5B from the bottom hits the support plate portion 21b of the stop shelf 21 and the guide plate 40, and the second large bottle 5B from the bottom is prevented from descending any further. Thereafter, as the interval β increases, only the lowermost large bottle 5A descends, and when the interval β becomes larger than the outer diameter of the large bottle 5, the lowermost large bottle 5A lowers. 5A falls into the chute 41 and is delivered to the product outlet 42. In this case, the large bottle 5A 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 bottle 5 will not be destroyed.

Next, when both first cams 14 rotate 87 degrees as shown in FIG.
4 and both second cams 22 are rotated in the direction of arrow F. Then, the rolling shelf 17 begins to rotate in the direction of arrow H, and when both first cams 14 return to 72 degrees, that is, 15 degrees to the initial state,
Both first cam rollers 18 pass through point b on the cam surface 15. Therefore, rolling shelf 17 is the 6th
The support plate portion 17b of the rolling shelf 17 is returned to its original state before the product is delivered as shown in the figure, and the support plate portion 17b of the rolling shelf 17 is
In other words, in this state, it is stopped with a slight gap between it and the bottom of the next lowermost large bottle 5B. Also, at this time, both second cams 22 do not rotate until the drive pin 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. It will rotate in the F direction. Therefore, the stop shelf 21 is in the state shown in FIG. 8, supporting the second large bottle 5B from the bottom. Next, when both first cams 14 further rotate in the direction of arrow F, both second cam rollers 24 descend from the large diameter part 23a to the small diameter part 23b of the cam surface 23,
The support plate portion 21b of the stop shelf 21 is lowered, and the bottom surface of the large bottle 5 is transferred to the support plate portion 17b of the rolling shelf 17, and the support plate portion 21b of the stop shelf 21 is separated from the large bottle 5, as shown in FIG. Return to state.

In the above embodiment, the driving means in the claims is composed of the elongated hole 25 and the driving pin 26.

Effects of the Invention As described above, according to the present invention, the first cam and the second cam
As the rolling shelf is rotated downward, the stop shelf is rotated upward by the cam and the driving means, and the second large bottle from the bottom is supported by the stop shelf and the guide plate, and its descent is restricted. Then, by rotating the rolling shelf, the bottommost large bottle passes between the both side plates of the stop shelf and is dispensed, so that the large bottle at the bottom can be dispensed at an early stage after the start of dispensing without waiting for the bottommost large bottle to pass. The second large bottle from the bottom can be supported by a stop shelf during dispensing, and the period of the large load acting on the large bottle during dispensing (the total load of the remaining large bottles) is shortened compared to conventional methods, and the dispensing process is It is possible to improve the situation where a large bottle is scratched. Therefore, even if the product is a large bottle whose surface is wrapped in a film wrapper, it can be dispensed without tearing the film wrapper.
