Description

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

(B) Conventional technology Conventionally, as shown in Fig. 1, a device for selling products in cup containers such as puddings having a truncated cone shape has a large diameter section A at the top and a small diameter section B at the bottom. 2 to 5 are generally used. That is, in FIGS. 2 to 5, 1 is a generally box-shaped product storage column with an opening 2 for filling products in the front, and 3 is a product storage column whose upper and lower ends can be freely rotated into the upper and lower parts of the column 1, respectively. It is connected to a driving device 4 on the upper part of the column 1 by a pivoted shaft, and is rotated half a rotation each time a product is sold. A support member 5 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 6 is provided at the center of the member 5. Reference numeral 7 denotes a first support member having a substantially semicircular fan shape and fixed to the shaft rod 3 slightly above the bearing 6, and is located at the top of each of the storage chambers 10A and 10B formed on the left and right sides of the column 1. It supports the lower-level products M1 and M2 and sequentially carries them out. Reference numeral 8 denotes a stopper member whose upper and lower ends are pivotally supported at the upper and lower front surfaces of the column so as to be able to slide left and right, respectively, to prevent the product M from protruding from the opening 2 and falling, when storing the product in the column. is for moving to the side end of the opening and widening the opening 2.

Guide members 9A and 9B guide the products M in the storage chambers 10A and 10B downward, and serve to substantially narrow the distance between the shaft rod 3 and the side wall of the column 1.

Reference numeral 11 denotes a second support member that supports products higher than the product M1 in the storage chamber 1B on the delivery side during delivery, and supports the collar of the product M with the side wall of the column 1.

Next, the operation of this conventional example will be explained. Second
3 and 3 are in a sales standby state, and the first support member 7 is the product M in both the left and right storage chambers 10A, 10B.
We support this. In this state, when the drive device 4 is energized by a sales command and the shaft rod 3 rotates approximately 90 degrees in the direction of the arrow, the state shown in FIGS. 4 and 5 is reached, and the support for the lowest product M1 is released. He will fall. Further, this type of device is disclosed in, for example, Japanese Patent Laid-Open No. 52-101575.

(c) Problems to be solved by the invention Storage chamber 10A that stores the products M as described above,
10B is formed in a size corresponding to the large diameter part A of the product M, so the small diameter part B is similar to the storage chambers 10A, 10.
Can move freely within B. Therefore,
When the support member 7 rotates, the small diameter portion B, which is the bottom of the lowest product, moves to the fourth position due to frictional resistance with the support member 7.
As shown in the figure, the bottom part was easily swung and fell over, and there was a risk that the product would get caught between the guide member 9B and the shaft 3, resulting in product jamming.

Furthermore, when the product is stored upside down with the small diameter side facing upward, as in the configuration shown in the above-mentioned publication, the above-mentioned overturning of the product almost never occurs. Depending on the contents of the product to be stored, for example, pudding, etc. may suffer from quality defects if stored upside down, and such products cannot be sold.

In view of the above points, the present invention provides a device that can prevent products stored in a normal posture from falling over.

(d) Means for solving the problem In order to solve the above problem, the present invention vertically installs a shaft rod inside the product storage column that rotates a predetermined amount each time a product is sold, and a conical rod is installed on both sides of the shaft rod. Trapezoidal product M
A first storage chamber is formed in which the products are stacked and stored, and the lowermost product in the storage chamber is unsupported by a predetermined rotation of the shaft rod and is dropped and carried out.
and a second support member that supports the product immediately above the lowest rank product when the first support member carries out the lowest rank product, and the product is arranged such that the large diameter part is on the upper side. The products are stacked and stored on the first support member, and the first support member and the second product are stacked in correspondence with the lowest product supported on the first support member.
A product guide member is provided on the shaft between the support member and the product guide member, the diameter of which is larger at the bottom than at the top.

(E) Function: A product guide member having a diameter larger at the bottom than at the top is provided on the shaft rod between the first support member and the second support member. The products are stacked and stored in a normal posture so that the highest product is on top, and the play space between the lowest product supported by the first support member and the shaft rod is reduced, so that the first product due to the rotation of the shaft rod is To prevent the lowest product from falling when the supporting member operates.

(f) Embodiment FIGS. 6 to 11 show embodiments of the present invention, and the same reference numerals as in the conventional example 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 connected to the drive device 4 in the upper part of the column 1 by a shaft whose upper and lower ends are rotatably supported in the upper and lower parts of the column 1, respectively, and is rotated half a rotation each time a product is sold. A support member 5 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 6 is provided at the center of the member 5. Reference numeral 7 denotes a first support member having a substantially semicircular fan shape and fixed to the shaft rod 3 slightly above the bearing 6, and is located at the top of each of the storage chambers 10A and 10B formed on the left and right sides of the column 1. It supports the subordinate products M1 and M2 and sequentially transports them. 8 is pivotally supported at the upper and lower front surfaces of the column so that its upper and lower ends can slide left and right, respectively, and the opening 2
This is a stopper member that prevents the product M from protruding and falling from the column, and when storing the product in the column, it moves to the side end of the opening and widens the opening 2. 9A and 9B are guide members that guide the products M in the storage chambers 10A and 10B downward, and serve to substantially narrow the distance between the shaft rod 3 and the side wall of the column 1. . Reference numeral 11 denotes a second support member that supports products higher than the product M1 in the storage chamber 1B on the delivery side during delivery, and supports the collar of the product M with the side wall of the column 1. Reference numeral 12 denotes a product guide member which is fixed to the shaft 3 directly above the support member 11 between the first support member 7 and the second support member 11, so that the lowest product M1 falls smoothly. It guides downward and has a truncated conical shape with a diameter larger at the bottom than at the top. The maximum diameter edge of this guide member 12 and the guide members 9A, 9B
The shortest distance D is set shorter than the small diameter portion B of the product M. In this embodiment, the guide member 12 has a truncated conical shape, but it may be shaped like a rocket, and various other modifications are possible.

The operation of the above configuration will be explained below.
First, FIGS. 6 and 7 are in a sales standby state, with the longitudinal direction of the first support member 7 being in the left and right direction, and both storage parts 10
We support product M in A and 10B. Next, when the drive device 4 is energized by a sales command, the shaft rod 3 rotates in the direction of the arrow. When the product M1 is rotated approximately 90 degrees as shown in FIGS. 8 and 9, the product M1 in the right storage chamber 10B is released from the support member 7 and falls downward to be carried out. At this time, the small diameter portion B at the bottom of the product M is guided by the product guide member 12 and is prevented from falling due to its rotation. That is, the rotation of the support member 7 causes frictional resistance with the product and the product is likely to fall, but since the distance D between the large diameter edge of the product guide member 12 and the guide member 9B is shorter than the small diameter portion B of the product M, the product The guide member 12 prevents the product from falling down and prevents it from getting caught between the shaft rod 3 and the guide member 9B, so that one product can be carried out without fail. Of course, at this time, the product M3 on the carry-out side is supported at its collar by the second support member 11 and the side wall of the column 1, and double carry-out is prevented. And furthermore, the shaft 3 is 90
When rotated once, the support by the second support member 11 is released, but the first support member 7 is now supported. However, the state again returns to the state shown in FIGS. 10 and 11, and the state is on standby for sales. The next item to be carried out is the lowest product M2 in storage room 10A on the left.
will be carried out, and in this way they will be carried out and sold one after another.

(g) Effects of the invention As described above, the invention has a structure in which the shaft is formed so as to protrude further into the storage chamber from the upper side to the lower side, corresponding to the lowest product supported by the first support member. Since the product guide member is provided to reduce the play space at the bottom of the lowest product supported by the first support member, even if the product is stored in the normal position, the lowest product The product can be prevented from falling over by the product guide member, and the product can be carried out reliably.
