Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a product dispensing device for a vending machine, and more particularly to a dispensing device suitable for rectangular or cubic products such as drinks in paper packs.

As this type of product delivery device, the Su-Guilal method, chain elevator method, and Hisland shelf method have been widely used.

However, in the above-mentioned spiral system, a spiral is fixed around a shaft extending in the vertical direction, and by rotationally driving the shaft to which the spiral is fixed, it is inserted into the gap between the spirals along both sides of the shaft. The inserted products were being carried out one by one from below. Therefore, in the spiral method, since the spirals are located between vertically adjacent products, the storage capacity of the products is reduced, and products must be inserted one by one between vertically adjacent spirals. This made filling work complicated.

One type of chain elevator is not only complicated and expensive9, but also has a small storage capacity9.
However, this method had the disadvantage of complicating the work of filling the product.

Furthermore, in the slant shelf system, the device is not only complicated and expensive, but also the storage capacity of the products is small, and the filling operation of the products is complicated. However, there were still drawbacks such as the falling distance of the transported product being long and the possibility of damage to the paper and sticks due to impact.

The present invention eliminates the disadvantages of the above-mentioned known product delivery devices, allows more products to be stored in a narrow space, and simplifies the device.

The present invention also provides a product delivery device for a vending machine that facilitates filling operations.

The present invention will be explained in detail below.

FIGS. 1 and 2 show two embodiments of the invention in a front view and a cross-sectional view, respectively, in a standby state.

In the figure, 1 is a product storage section with the front and bottom open.

11. 12, 13, and 14 are the top plate, left side plate, right side plate, and back plate of the product storage section 1, respectively. 15 is product storage section 1
It is a front plate fixed to the lower front side of the. Flange shafts 2, 2 are removably provided on the lower middle part of the back plate 14 and the corresponding front plate 15, respectively, so as to be on a straight line in the front and back direction within the product storage section 1. . 3,3
' are flanges installed astride the flannel shafts 2, 2 so as to be rotatable about them. Reference numeral 5 denotes a rotating shaft provided in the center of the product storage section 1 so as to extend in the vertical direction, and its lower end is pivotally supported by a pivot 16 attached to the back plate 14. The upper end of the rotating shaft 5 is connected to a bearing 17 provided on the top plate 11.
It is connected by a pin 19 to a connecting member 18 which is rotatably fitted into the connecting member 18 . In this way, the shaft 5 is made rotatable. At the bottom of the rotating shaft 5 are flat rods 3, 3' which are in a horizontal state.
A sector-shaped rotation control plate 6 is fixed at a position where it can come into contact with the lower surface of.

7.7' is a flapper which has the same structure as the flapper 3.3+ and is pivotably supported. These hula.

・e7.7' is the flapper 3, 3' that is on standby for sale.
``-'' products 8, 8' are provided at a position where they can be engaged with the second product. In Figs. 2, 5, and 7, the flannel "7 r 7' is not shown. 9 indicates rotation 1.
This is an arm that alternately drives the flapper 7.7' as the flapper 7.7' rotates, and is fixed to the rotating shaft 5 slightly below the shaft support of the flapper 7.7'. FIG. 3 shows a perspective view of the attachment structure of the flanopuff, 7', and arm 9. The support shafts 10 and 10 of the flannel R7t 7' are respectively provided on the front part of the product storage section 1 corresponding to the back plate 14 and the flannel 1, Q7, 7' so as to extend in the same direction as the flapper legs 2, 2. The front plate 15' is removably fitted with a salt cover. Of course, the front plates 15 and 15' may be a single plate. The arm 9 rotates the flannel/mother 7 (
7') upward, and its length is 90° (or 2') in the direction of the arrow from the position shown in Figure 1.
70°), product 8 (or product 8')
The value is set such that 1 product can be inserted between the flapper 7 and the left side plate 12 (or the flapper 7' and the right side plate 13).

Note that the connecting member 18 connects the motor 20 with a speed reduction mechanism and the shaft 5. The motor 20 rotationally drives the shaft 5 and the cam portion 21 . Then, by the recesses 21a formed in the cam part 21 at an angular interval of 1800 degrees and the switch 22 provided opposite to the periphery of the cam part 21.

The shaft 5 can be driven intermittently by 180 degrees.

Next, the effect of carrying out the product will be explained.

First, fill the product storage section 1 in the state shown in Figure 1.
They are stacked and stored on the flaps /#3, 3' on the left and right sides of the inner shaft 5.

When the motor 20 is energized in response to a sales signal based on the insertion of a predetermined coin in the sales standby state, the rotation control plate 6 and the arm 9 are driven in the direction of the arrow in FIG. Rotation control plate 6
The flapper 7 is driven upward by the ATM 9 at a rotation angle slightly before it leaves the flapper 3, and begins to sandwich the product 8'' immediately above the product 8 between it and the left side plate 12.Fourth As shown in FIG.
When rotated by 0°, the flanges 3 are released from the locked state and rotated downward around the shaft 2, and the product 8 placed on the flanges 3 is dropped and carried out. However, the quotient directly above it “y,;
, 8rt is held between the flan puff and the left side plate 12, so it does not fall. Continue with the rotation control plate 6. Arm 9
rotates as shown in Figures 6 and 7.

It stops when it has rotated 180 degrees from its initial position.

At this time, the flapper 3 is also pushed up and returned to its original horizontal position as the rotation control plate 6 rotates, and the flapper 7 rotates downward as the arm 9 rotates.

Then, the next item 8'' and the item above it are stuck on top of Fran-G3, who has returned and falls out without being released from the sandwiched state.

When the next sales signal arrives, the product 8' is dropped and carried out in a similar manner.

Here, flapper 3, 3', flapper 7.7' are:
- Since the product is substantially axially supported by a support shaft located on a straight line, the space occupied in the product storage section 1 can be small.

Moreover, this pivot support does not become an obstacle when the product is dropped and carried out. This allows the width dimension of the product storage section 1 to be reduced.

Moreover, compared to the conventional method described above, it is possible to store products by stacking them, so a large number of products can be stored. In addition, with reference to FIG. 3, a cut 'H' is made in each of the edges of the fly y i47 *7' corresponding to the shaft 5 so that the shaft 5 can be inserted therein.
, 71' are provided. This is to ensure that the rotation angle when the arm 9 is released is not restricted by the shaft 5, so that the downward movement of the product is not hindered. The same is true for furan iE 3 , 3', respectively on the edges corresponding to axis 5 of furan/X 3 p 3'.

By providing a notch into which the shaft 5 can be inserted, it is possible to smoothly drop and carry out the product.

The present invention is not limited to the above-mentioned embodiment, and for example, the flappers 3 and 3' are not limited to being supported on one shaft, but may be supported on separate shafts.

It goes without saying that the unloading device is not limited to one stage, but may have multiple stages. Furthermore, the left side plate 12. The inner wall of the right side plate 13 has a surface treatment that increases the frictional resistance of the surface (for example, a rubber sheet pasted on the surface, serrated protrusions, etc.) to prevent the product from falling when the product is sandwiched between the sides. ).
