Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a product delivery device for a vending machine.

(b) Prior Art Various product dispensing devices for vending machines that store and sell box-shaped products such as beverage products in paper containers have been known in the past. A product discharging device is equipped with a transport mechanism that moves vertically, as in the invention of the invention, and a sales mechanism that transports and sells the products transported by this transport mechanism in a horizontal direction, or as shown in FIG. A product delivery device is known. That is, in FIG. 1, 1 is a generally box-shaped product storage column with an opening 2 for filling products in the front, and 3 is a spiral-shaped product storage column whose upper and lower ends are rotatably supported in the upper and lower parts of the column 1, respectively. (Spiral) A shaft rod with 4 continuously wrapped around the entire upper and lower part, 5 is provided at the top of the column, and is connected to the upper end of the shaft 3 to rotate the spiral 4 180 degrees every time a product is sold. This is a drive device that controls the delivery of product A from the lower end of the spiral. The product A to be stored and sold is stored between the spiral sides B on the left and right sides of the shaft 3, respectively. Further, a support piece 7 is fixed to the lower end of the column 1 in the front-rear direction so as to divide the column 1 into two, and a bearing 8 is provided at the center of the support piece 7. Due to the unique shape of the spiral side B in column 1, the product storage chamber in such a vertical spiral system requires an extremely larger gap than the size of the product A to be stored, so the number of products stored and sold is limited. In addition, the former product delivery device has the disadvantage that it is complicated and expensive.

On the other hand, as a product discharging device that can increase the number of products stored and sold, for example, as seen in Japanese Patent Laid-Open No. 101575/1982, the product in a tapered container is inverted and placed on a gate serving as a means for discharging the product. A configuration is known in which, when stacking and storing the lowest tapered product, the product is carried out by the product carrying means, a support plate is advanced below the second product from the lowest to support the product. .

(c) Problems to be solved by the invention The product carrying device having such a structure supports the lower surface of the product by advancing the support plate into the tapered space formed by the product located below the product to be supported. Therefore, it cannot be used as a product delivery device for transporting box-shaped products that do not form a tapered space when stacked and stored. In other words, it is extremely difficult to manage dimensions when inserting and advancing the support plate between box-shaped products that are stacked and stored, and if the support plate cannot be inserted and advanced between the products, the edges of the support plate may There was a risk that the product would be cut directly into the product, causing a lock condition and making it impossible to sell the product. In addition, the support plate extends below the product to be supported and supports the product only after the lowest product falls from the transport means, so all product loads are placed on the gate serving as the transport means. The drive device must be rotated under such conditions, which places a large burden on the drive device.

In view of the above, the present invention provides a product dispensing device for a vending machine that can stack and store box-shaped products and carry them out, and also provides a smooth product discharging operation.

(d) Means for solving the problem: A control member provided on the shaft at a position above the support member, and a rotatable member located opposite the control member and facing the second product from the bottom. a pushing member having a pressure bearing surface provided at the bottom, and when the lowest product is carried out by the support member, the control member presses the pressure bearing surface against the second product from the lowest, and the product is stored. It is configured so that it is supported by pressure between it and the side wall of the chamber.

(E) Effect This invention is such that when the support member carries out the lowest product, the control member presses the pressing bearing surface of the pushing member against the second product from the lowest, thereby pushing the product against the side wall of the product storage chamber. Press and support between.

(F) Embodiment Figures 2 to 9 show a product delivery device according to an embodiment of the present invention, and the same reference numerals as the conventional example in Figure 1 indicate the same or similar items. .

1 is a roughly box-shaped product storage column with an opening 2 for filling products in the front; 3 is a shaft whose upper and lower ends are rotatably supported in the upper and lower parts of the column 1; and 5 is the upper part of the column. This drive device is connected to the upper end of the shaft 3 and rotates the shaft 3 180 degrees every time a product is sold to carry out the lowest product A1 in the storage column 1. A support piece 7 is fixed to the lower end of the column 1 in the front-rear direction so as to divide the column 1 into left and right halves, and a bearing 8 is provided at the center of the support piece 7. Reference numeral 9 denotes a substantially semicircular fan-shaped product support member fixed to the shaft 3 above the bearing 8, and is used to support and carry out at least the lowest product A1. On the other hand, on the left and right sides of the storage column 1 are product storage chambers 10A and 1 for storing the product A.
0B is formed. Reference numerals 11A and 11B are supporting parts protruding from the inside of both side walls 1A and 1B of the column 1, which support one lower end of the lowest product A, and are provided at symmetrical positions. 12A, 12
Reference numeral B designates a pushing member whose upper end is rotatably supported by penetrating support shafts 13A and 13B, and whose cross section is in the shape of a square. That is, when the pushing members 12A and 12B are rotated outward by the control member 14, which will be described later, the product A
by its pressing bearing surfaces 12C and 12D.
A, 1B, said support parts 11A, 11B
It is possible to support the product A in both storage chambers 10A, 10B except for the lowest product A1 in cooperation with the press support surfaces 12C, 1 in the standby state.
2D is engaged with two products A directly above the lowest product A1. Reference numeral 14 denotes a control member having a similar shape to the product support member 9, and is engaged with the pushing members 12A, 12B symmetrically with respect to the shaft rod 3, although it is at a different level on the side opposite to the support member 9 on the shaft rod 3. Fixed in possible position. When the control member 14 abuts and engages with one of the pushing members 12A, 12B when the shaft rod 3 rotates, one of the pushing members 12A, 12B rotates and the product A by pushing it into contact with either of the side walls 1A, 1B, and supporting the product A in either of the storage chambers 10A, 10B together with any of the supporting parts 11A, 11B,
This prevents it from falling downward.

The operation of the above configuration will be explained below.
First, in the sales standby state, as shown in FIGS. 2 and 3, the support member 9 supports the lowest product A1, and the control member 14 supports both pushing members 12A, 1.
2B and rotate both members 12A, 12B to push the products A3, A5 and A2, A4 to both side walls 1A, 1B of the storage column 1, so that they cooperate with the supporting parts 11A, 11B. Working and both product storage room 10
It supports product A in A and 10B to prevent it from falling.

Next, when a sales command is issued by inserting a predetermined amount of coins, the drive device 5 is energized and the shaft 3 also rotates in the direction of the arrow. With the rotation of this shaft 3, the lowest product A
1 and the support member 9 gradually decrease and eventually rotate approximately 90 degrees, the engagement is released and the pushing member 12B is removed as shown in FIGS. 4 and 5.
The engagement between the control member 14 and the control member 14 is also released. Therefore, the lowest product A1 is dropped and carried out and reaches the sales outlet (not shown), and the product A in the right storage chamber 10B is lowered and supported by the support member 9. Then, when the shaft rod 3 rotates further by 90 degrees, the control member 14 engages with the pushing member 12A as well as the other 12B again and rotates, as shown in FIGS. 6 and 7. Then, the products A4 and A6 in both storage chambers 10B are pressed against the side wall 1B by the pressing support surface 12D and supported in cooperation with the support portion 11B. In this way, the support member 9 now supports the product A2 and is in a sales standby state. At this time, product A
3, A5 remains pressed by the pushing member 12A and the support portion 11A.

Regarding the next sale, the sales command is issued as described above, and the drive device 5 moves the shaft rod 3.
When rotated 90 degrees, as shown in FIGS. 8 and 9, the engagement between the lowest product A2 and the support member 9 is released, but the products A4 and A6 in the right storage chamber 10B are removed.
Since it is supported by the pushing member 12B and the support part 11B, only the product A2 is carried out, and the product A3 in the left storage chamber 10A is supported by the support member 9. Eventually, the shaft 3 rotates another 90 degrees.
When the control member 14 is rotated by 180 degrees, the control member 14 further engages with both the pushing members 12A and 12B, and the product A3 is placed at the lowest position as shown in FIGS. 2 and 3.

In this way, the lowest grade products are taken out alternately from the left and right storage chambers at the time of sale.

(g) Effects of the invention As described above, in this invention, when the lowest product is carried out by the support member, the control member presses the pressing bearing surface of the pushing member against the second product from the lowest, and the product is moved. Since it is pressed and supported between the products and the side wall of the product storage chamber, there is no locking between the products and the products, and even box-shaped products can be stacked and stored for sale. In addition, when carrying out the lowest product using the support member,
Since the second product from the bottom is supported by the pushing member, the product load applied to the support member during the unloading operation is only the one product at the lowest rank to be taken out. Compared to the one disclosed in Japanese Patent No. 52-101575, the support member can carry out the unloading operation very smoothly, and other effects not found in the prior art can be achieved.
