Description

[Detailed description of the invention] [Technical field to which the invention pertains]

This invention is a vending machine that stores various products such as cans and single paper packs of bottles in a direct stacking manner in a shelf, and drops the products one by one from the lowest level based on a sales command. Regarding product delivery equipment.

[Prior art and its problems]

For example, in the 1980s, a direct stacking product shelf product delivery device became popular as a product delivery device for selling cans, bottles, and two-paper pack products of various beverages such as soft drinks and milk.
This is known from, for example, Japanese Patent No.-166081. Such a direct stacking type product shelf is different from a product shelf consisting of open-bottom containers, in which the products are sorted into two rows on the left and right and stored in a direct stacking manner, and the product delivery device is used to store the products on the shelf in relation to the rows of stored products. A swinging and opening type product carrying out flapper is placed at the lowest position to place and hold a row of products while waiting for sales, and a swinging and opening type product holding flapper is placed opposite the second product from the bottom. , and a control cam driven by a bend motor that swings and controls each flapper in accordance with the sales operation. When a sales command is given in this configuration, the bend motor is started, and the product holding flapper is tilted via the control cam so as to be pushed out from the hanging position toward the product row side, and the second and subsequent products from the bottom are moved in that position. While temporarily holding the product, the product carry-out flapper is opened downward to allow the lowest product to fall and be carried out. When the product ejection flapper returns to its original horizontal position, the product holding flapper closes and
The products stored in the shelf that were previously held by the product holding flapper are no longer restrained and fall freely within the shelf, landing on the product carrying out flapper and returning to the sales standby state again. On the other hand, in order to improve the above-mentioned product delivery device and reduce the impact of products falling on the shelf during product delivery to prevent damage and deformation of product containers, as well as to prevent beverage foaming in the case of carbonated beverages, the above-mentioned product delivery device was improved. The product holding flapper is used as the first product holding flapper, and a second component holding flapper and its control cam are additionally installed at a middle position in the shelf, and the products stored in the shelf are temporarily held in that position when the product is taken out. Among the first and second product holding flappers, the same applicant has proposed a structure in which the second product holding flapper closes slightly later than the first product holding flapper. Here, the configuration and operation of the product delivery device will be explained with reference to FIGS. 4 to 7. In each figure, 1 is a product storage shelf with an open bottom surface, and products 2 are stored in this shelf in two rows on the left and right in a direct stacking manner. On the other hand, in the center of the product storage shelf 1, a vertical rotary drive shaft 4 connected to a bend motor 3 at the top is arranged, and on both sides of the lowest part of the shelf with this rotary drive shaft 4 in between, An open-type product carrying-out flapper 5 is provided. This product delivery flapper 5 has a control cam 6 which is a semicircular plate provided on the rotational drive shaft 4.
In the sales standby state, the product 2 is supported from below in a horizontal position and held thereon, and when the support is removed by rotation of the control cam 6, the flapper 5 swings downward and opens. be done. On the other hand, above the parts carrying out flapper 5, there is a first product holding flapper 8 which faces the second product from the bottom and is controlled to swing by a control cam 7, and further above, at a middle position in the shelf, there is a first product holding flapper 8 which faces the second product from the lowest. A second product holding flapper 10 whose swing is controlled by a cam 9 is provided. Further, the control cams 7 and 9 are both in phase with each other, and are mounted on the axis of the rotary drive shaft 4 with a phase angle of 90 degrees set between them and the control cam 6 of the product delivery flapper 5. The cam width of the control cam 9 is set to be slightly wider than the cam width d of the lower control cam 7 in the latter half region. Note 11
is a partition wall that separates the left and right product storage columns within the shelf. Next, we will explain the product delivery operation with the above configuration.
First, FIG. 4 (al, (bl) shows the sales standby state, and the left and right product carry-out flappers 5 are supported in a horizontal position by the control cam 6, and in this state, all the products stored in the shelf are transferred to the product carry-out flappers 5. In this state, both the first and second product holding flappers 8 and 10 are in a hanging position. When a sales command is given from this sales standby state, the bend motor 3 is started. When the drive shaft 4 is rotated by 90 degrees during this process, the fifth
As shown in figures (al and (bl), the product holding flapper 8.10 on the left row side of the shelf is pushed by the control cam 7.9 and tilts so as to protrude toward the product row side, and the product that is lined up second from the bottom and While the product in the middle position of the shelf is pressed from the side against the side wall surface of the shelf 1 and held in that position, at the same time, the product carry-out flapper 5 on the left row side of the shelf disengages from the control cam 6 and moves downward. It swings to open the product aisle.As a result, only the lowest-ranked products on the left row fall down the shelf as shown by arrow P and are carried out. The products are held in storage positions within the shelf by the first and second product holding flappers 8 and 10. From this state, the rotation of the drive shaft 4 further progresses, and as shown in FIG.
), (When the rotation angle reaches 160 degrees as shown in bl, the product carrying out flapper 5 is pushed up by the control cam 6 and returns to the horizontal position again, while the first product holding flapper 8 and The vli control cam 7 is disengaged, becomes free before the second product holding flapper 10, and closes in a hanging position. The products lined up in the lower row fall in the direction of the arrow through a drop equivalent to one product and land on the product delivery flapper 5. At this point, the second product holding flapper 10 is pressed against the control cam 9. The remaining stored products lined up on the upper shelf within the shelf remain held by the second product holding flapper 10.The rotation of the drive shaft 4 further progresses, and as shown in FIG. b
), when the rotation angle approaches 180 degrees, the second product holding flapper 10 and the control cam 9 are disengaged slightly later than the first product holding flapper 8, and as a result, the second product holding flapper
The product on the upper shelf within the shelf, which was held by the product holding flapper 10, falls as shown by arrow B and lands on top of the product that has already landed in advance. At the same time, the bend motor 3 is stopped and the state returns to the sales standby state shown in FIG. 4. If a sales command is given again here, the lowest order product will be carried out from the right column in the same manner as above. As can be seen from the above explanation, when the products are taken out, the stored products temporarily held in the shelves do not all fall at the same time, but are divided into two groups and fall separately. Therefore, the landing impact force caused by falling products is alleviated,
Deformation and breakage of products such as cans and bottles and foaming of the contents can be prevented, and since the impact force applied to the product delivery flapper 5 is alleviated, the occurrence of failures in the delivery mechanism is reduced accordingly. By the way, in this type of product delivery device, when changing the product to be sold, it is necessary to change the tilting angle of the product holding flapper, that is, the amount of push into the aisle, depending on the product type, especially the product size. This is shown in Figures 8 to 10.
To explain with a diagram, first of all, Fig. 8 shows a case where a large-diameter can product is handled as the product 2. In order to correctly hold the product 2 in the shelf, the pushing amount H1 of the product holding flapper 8 must be kept relatively small. It is necessary to set it to . On the other hand, for products in paper packs that are easily deformed as shown in Fig. 9, it is necessary to set the extrusion amount H2 of the product holding flapper 8 to be slightly larger than that shown in Fig. 8. It is not possible to securely hold the product between the wall and the product, and as shown in Figure 10, in the case of small-sized paper pack products, if the product holding flapper is not pushed out enough, the product will not be held and will fall off. In this case, the product holding flapper 8 is pushed out 1113
needs to be set even higher. On the other hand, in order to change the extrusion amount of the product holding flapper from H1 to H3 according to the product size as described above, conventionally, the upper end of the flapper is fixedly supported by a shaft as shown in FIGS. 11 and 12. For the swing-type product holding flapper 8, a control cam 7 facing the product holding flapper 8 is moved up and down in the direction of arrow X to variably adjust the pushing amount of the product holding flapper 8. Also, for this purpose, the control cam 7 is slidably fitted loosely onto the drive shaft 4 of the bend motor.
A long groove 72 opened in the boss part 71 is engaged with a key 41 attached to the drive shaft 4 to prevent rotation, and a method is adopted in which the boss part 71 is fixed at each of the upper and lower adjustment positions with a fixing screw 73. There is. However, when adjusting the movement of the control cam 7 using the above adjustment method, it is necessary to operate the fixing screw 73 from the front of the product storage shelf using the driver 12 as shown in FIG. The screw holes cannot be clearly seen, and the screws cannot be operated unless the direction of the control cam 7 is adjusted. In a product carrying out device equipped with a product holding flapper, each time the product is changed, the position of the control cam must be adjusted individually for each of the upper and lower control cams, making the adjustment process increasingly troublesome. This results in a decline in service quality.
