DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product dispensing device, particularly a flapper dispensing type product dispensing device.

Conventional technology Conventionally, this type of product dispensing device was developed by
63-3091, etc. Figure 3 is a vertical cross-sectional view of a product dispensing device of the flapper dispensing method, in which holders 1 and 2 are pivoted by shafts 3 and 4, respectively, and both holders 1 and 2 can be rotated downward in a single manner. is regulated by a cam plate 5. The cam plate 5 has a semicircular shape and is fixed to the tip of the camshaft 6 so that it can rotate horizontally. 7 are the products in the first column stacked on the pedestal 1, which are numbered I ₁ , I ₂ , I _{3 .} . . from the bottom to the top. 8 is the product in the second column stacked on pedestal 2, and similarly ₁ ,
Label them ₂ , ₃ , etc. Reference numerals 9 and 10 denote first and second stoppers, which are pushed out by a cam body 11 fixed to the camshaft 6 to stop the second product from the bottom of the first and second columns on the stocker wall surface 12.
It is pressed to the side to support the second or more stacked products. Reference numeral 13 denotes a product outlet provided in the front door 14 of the vending machine body, and 15 a table located below the first and second columns, the tip of which extends near the product outlet 13. Reference numeral 16 denotes a bar conveyor on which bars 17 are attached at appropriate intervals, and the bars 17 in the path are placed on the table 15 so that the products 7 and 8 that have fallen onto the table 15 are pushed out by the bars 17 toward the product takeout port 13 [in the direction of arrow A]. is passing through.

The rotation of the camshaft 6 is driven as follows by a motor [not shown], a stop cam [not shown] attached to the camshaft 6, and a cam switch [not shown] that detects the state of this stop cam. is controlled by. Note that the description will be made assuming that products 7 and 8 in the first and second columns are the same product, and that product payout is executed from the first or second column each time a payout instruction is detected.

Figure 5 shows I ₁ at the first payout instruction detection, and the second
The state of the cradle 1, 2 and the cam plate 5 in the process of dispensing ₁ upon detection of the dispensing instruction for the second time is shown. Figure 5 a is the third
The initial state of the figure and FIG. 4 is shown. When the first dispensing instruction is detected, the cam plate 5 rotates 90 degrees clockwise as shown in FIG. 5b, and the cradle 1 and the cam plate 5 are disengaged from each other. In addition, in this way, the cam plate 1
When the pedestal 1 rotates downward by 90 degrees,
As shown in FIG. 6, the second product ₂ is pressed against the stocker wall 12 by the cam body 11 in advance, and when the pedestal 1 rotates downward, only the product ₁ falls. The product I ₁ that fell onto the table 15 is moved to the table 1 by the bar conveyor 16 that has started the transfer.
5 in the direction of arrow A and delivered to a position facing the product take-out port 13, and the driving of the bar conveyor 16 is completed.

When the dispensing of the product ₁ is completed in this way, the cam plate 5 is further moved as shown in FIGS. 5b to 5c.
It rotates 90 degrees to push up the pedestal 1 which had been rotated downward, and releases the product ₂ from being pressed by the cam body 11. When the second payout instruction is detected,
The cam plate 5 rotates 90 degrees as shown in Fig. 5c to 5d, and the engagement between the pedestal 2 and the cam plate 5 is disengaged, and the product ₁ falls onto the table 15 as shown in Fig. 7. Then, in the same way as product ₁ , it is delivered on the bar conveyor 16,
The initial state shown in FIG. 5a is restored.

Problems to be Solved by the Invention With such a conventional configuration, no particular problem occurs when the products 7 and 8 are relatively lightweight, such as "250ml or 200ml in a brick pack." When products are heavy and large, such as a 1000 ml brick pack, the conventional small pedestals 1 and 2 cannot support the stacked products.

Therefore, as shown in FIG. 8, it is conceivable to make both the pedestals 1' and 2' have a large receiving area, but in this case, the following problem arises.

In other words, the distance _L1 between the table 15 and the lower end of the open pedestal 2' is narrower than the conventional distance _L0 ,
Among the first and second columns, the product 8 in the second column on the upper side in the transport direction [direction of arrow A] is spaced L ₁
become unable to pass through. Therefore, it is required that the distance _L2 between the stocker body 26 and the table 15 be made larger than in the past. However, because the height of the vending machine body is limited, it is currently impossible to provide the necessary interval _L2 .

An object of the present invention is to provide a product dispensing device which can accommodate heavy products and can reliably dispense the products to a product takeout port 13 even if the interval _L2 is the same as the conventional one.

Means for Solving the Problems The product dispensing device for a vending machine of the present invention has first and second pedestals, each of which is pivoted at one end so as to be rotatable downward, with their pivot axes facing outward from each other. The rotation is achieved by supporting the first and second pedestals with first and second cam plates which are arranged below the first and second pedestals and are pivoted to horizontally rotate. Directly stacked products are placed astride the first and second pedestals whose downward rotation is restricted, and when taking out products, the second product from the bottom of the stacked products is placed facing them. A stopper protruding from one of the stocker wall surfaces presses the product against the other stocker wall surface to restrict the descent of the product, and also rotates a first motor that rotationally drives the first cam plate and a second cam plate. The lowest product among the stacked products is removed by energizing the second driving motor to release contact between the first pedestal and the first cam plate, and the second pedestal and the second cam plate. It is characterized by being configured to pay out.

Function According to this configuration, the directly stacked products stacked in a row are supported by two pedestals, the first pedestal and the second pedestal. At the time of dispensing, the first and second motors are energized, the first and second cam plates rotate together, and both the first and second cradle are opened.
Only the lowest product whose descent is not regulated by the stopper is paid out.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Components having the same functions as those in FIGS. 3 and 4 are designated by the same reference numerals, and their explanations will be omitted.

FIG. 1 shows the product dispensing device of the present invention, which includes camshafts 18, 19, pedestals 20, 21, and cam plate 2.
3 in that two motors (not shown) for driving camshafts 18, 19 and 2, 23 are added.

That is, the product 7 in the first column is supported by the pedestals 1 and 20 arranged so that the shafts 3 and 24 are on the outside of each other, and the pedestal 20 is supported by a cam attached to the lower end of the camshaft 18. It is supported by a plate 22 and its downward rotation is restricted. Similarly, the products 8 in the second column are supported by pedestals 2 and 21 arranged such that the shafts 4 and 25 are outside each other, and pedestal 21 is supported by a cam attached to the lower end of the camshaft 19. It is supported by a plate 23 and its downward rotation is restricted.

FIG. 2a shows the standby state of the pedestals 1, 20, 2, 21 and the cam plates 5, 22, 23. When dispensing the product 8 in the second column, rotate the camshaft 6 90 degrees clockwise and rotate the camshaft 19 as shown in Figure 2b.
is rotated 90 degrees counterclockwise to release the engagement between the pedestal 2 and the cam plate 5 and the engagement between the pedestal 21 and the cam plate 23, thereby opening the pedestals 2 and 21. merchandise
After ₁ falls, the camshafts 6 and 19 are returned to their original positions to close the pedestals 2 and 21.

The same is true when dispensing the products 7 in the first column. From the state shown in FIG. It's open.

With this configuration, products 7 and 8 were supported by pedestals 1 and 20, and 2 and 21, respectively, so product 7 was supported only by pedestal 1 and product 8 by pedestal 2 as in the past. The receiving area is larger compared to
You can definitely support it. In addition, since the pedestals 1 and 20 and 2 and 21 are divided into two pieces, the table 5 Since the distance between the two columns is as wide as _L0 , even products in the second column on the upper side in the transport direction [direction of arrow A] of the first and second columns can be reliably transported to the product takeout port 13. .

Furthermore, since the first and second columns are arranged along the conveyance direction, the camshaft 6, the driving motor of the camshaft 6, the cam plate 5, and the cam body 11
etc. can be shared between the first column and the second column, contributing to cost reduction.

In the above embodiment, the second product from the bottom is pressed against the wall of the stocker to restrict its descent, but this product is also pushed out by the cam body 11 and the cam body 11 in the same way as the camshaft 6. A third stopper 9' or a fourth stopper 10' is provided as shown in the phantom line in FIG. 1, and the product 7 is held between the first and third stoppers 9, 9'.
The same effect can be obtained even if the product 8 is clamped by the second and fourth stoppers 10, 10' to restrict the descent of the second product.

Effects of the Invention As explained above, the product dispensing device of the present invention has the following features:
Since the products in one column are supported by two pedestals, the first and second pedestals, the receiving area is larger than before, and even heavy and large products can be supported reliably. The pedestal is the first and second pedestal.
Because it is divided, the distance _L0 between the lower end of the open pedestal and the conveyance surface does not become narrower than when supported by a single pedestal, and the height of the vending machine body can be lowered than before. The product can be reliably delivered to the product outlet without increasing the price.
