Description

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

2. Description of the Related Art Conventionally, this type of product dispensing device has been constructed as shown in FIGS. 5 to 10. FIG. 5 is a longitudinal sectional view of the product dispensing device, with shafts 3 and 1.2 respectively. The downward rotation of both pedestals 1 and 2 is regulated by a cam plate 5 on the instep. The cam plate 5 has a semicircular shape and is fixed to the tip of a camshaft 6 that can rotate horizontally. 7 is the first column of products stacked on the pedestal 11-, and here they are numbered 11.12, lx, . . . from the bottom to the top. 8 is the product of the second column stacked on the pedestal 2, and the symbols 1-JG) are placed on the same sphere as L, II2, II3, etc. 9.10 are the first and second stoppers, which are pressed against the cam body 11 fixed to the force holder 1 door 71-6 to push the second product from the bottom of the first and second columns. Press it against the stocker wall 12 side to support the second or higher stacked products. 13 is the product outlet provided in the front opening 14 of the white rice vending machine body, 15 is the first and second
21 is a table located below the ram, and its tip extends near the product takeout port 13. Reference numeral 16 denotes a bar conveyor on which bars 17 are attached at appropriate intervals, and the bar 17 on the outbound path is used to push out the products 7 and 8 that have fallen onto the table 15 toward the product takeout port 13 (in the direction of the arrow). It has passed over 15.

^C1 The rotational drive of the camshaft 6 is omitted, the motor [i shown in the diagram! ! ] and a stop cam [not shown] mounted on the camshaft 12 and the foot 6; and a cam switch [not shown (not shown) 1 for detecting the state of this stop cam, which is controlled as follows. There is. J3, product 7 in the first and second columns
and 8 are the same product, and the product will be described as being dispensed from the first or second column each time a dispensing instruction is detected.

FIG. 7 shows the state of the cradle 1, 2 and the cam plate 5 in the process of ejecting 11 when the first dispensing instruction is detected and (1) when the second dispensing instruction is detected. The seventh time shows the initial state of FIGS. 5 and 6. When the first dispensing instruction is detected, the cam plate 5 rotates 90° clockwise as shown in FIG. 7, and the cradle 1 and the cam plate 5 are disengaged from each other. In addition, in this J, the sea urchin cam plate 1 rotates 90 degrees and the pedestal 1 rotates downward! At the time of IJ'', the second product I2 is pressed against the stocker wall 12 by the cam body 11 as shown in FIG. falls.

The product 1 that has fallen onto the table 15 is sent on the table 15 in the direction of the arrow by the bar conveyor 16 that has started its transfer and delivered to a position facing the product take-out port 13, and the drive of the bar conveyor 16 is completed.

When the delivery of the product 1 is completed in this way, the cam plate 5 further rotates 90 degrees as shown in FIG.
Release the pressing of product ■2 by. When the second dispensing instruction is detected, the cam plate 5 rotates 90 degrees from the seventh time to the seventh time, and the engagement between the pedestal 2 and the cam plate 5 is disengaged, as shown in FIG. Product ■1 falls onto the table 15 and is delivered on the bar conveyor 16 in the same manner as product 11,
Return to the initial state for the 7th time.

Problems that Komei is trying to solve With this conventional configuration, no particular problem occurs when the product 7.8 is a relatively lightweight product such as 25 On [or 200 NJ2 J Shimaro with a brick bag].
When the products are heavy and large, such as 100 nΩJ in a brick pack, the conventional small pedestal 1.2 cannot support the stacked products.

Therefore, it is conceivable to make both the pedestals 1' and 2' with a wide pedestal area as shown in FIG. 10, but in this case, the following problem arises.

That is, the distance L1 between the table 15 and the lower end of the open pedestal 2' is narrower than the conventional distance Lo, and the first and second
Among the columns, the products 8 in the second column on the upper side in the conveyance direction (in the direction of the arrow) cannot pass through the interval L1. Therefore, the distance L between the stocker main body 26 and the table 15 is
2 is required to be larger than before. but,
Due to the limited height of the rice vending machine body, it is currently not possible to provide the necessary distance L2.

The present invention is capable of accommodating heavy items, and has a space [
Even if -2 is the same as before, the number of products is r11 Shiro1
An object of the present invention is to provide a product dispensing device capable of dispensing products in a single manner.

Means for Solving the Problems In the product dispensing device of the present invention, first and second pedestals, each of which is pivoted at one end so as to be pivotable downward, are arranged with their pivot shafts facing outward. The first and second pedestals are supported by first and second cam plates which are pivoted to horizontally rotate above the first and second pedestals. The product is placed across the first and second pedestals, whose rotation is restricted and downward rotation is restricted, and when the product is taken out, the second product from the bottom of the stack is placed. In addition to regulating the descent of the product, the first
The second cam plate is rotated by a predetermined angle to release the contact between the first cradle and the first cam plate, and the second cradle and the second cam plate, so that the bottom end of the stacked products can be removed. The structure is configured to dispense products, and the dispensed products are transferred to the first item. A conveyor is provided for conveying the products to the product take-out port along the arrangement direction of the second pedestals, and the first. The rotation driving means for the second cam plate is connected to the first cam plate.
．． The cradle on the lower side of the conveyor conveyance direction behind the second cradle is rotated downward before the cradle on the upper side.
It is characterized by being configured so that +1 is canceled.

Function: According to this configuration, one product is supported from both sides by the first pedestal and the second pedestal, and when the first and second pedestals are opened, the lower side in the conveyor transport direction is lower than the upper pedestal. Open first.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. Incidentally, those having the same effect as those shown in FIGS. 5 and 6 are given the same symbol and their explanation will be omitted.

Figure 1 shows a product dispensing device made by Kikomei, with the addition of a camshaft 18.19, a pedestal 20.21, a cam plate 22.23, and a 21[X] motor that drives the camshaft 18.19. Dots in particular? It is different from the A5 diagram.

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 plate attached to the lower end of the camshaft 18. 22 to restrict downward rotation. Similarly, product 8 in the second column is on axis 4 and 25.
The cradle 21 is supported by a cam plate 23 attached to the lower end of the camshaft 19, and its downward rotation is restricted. ing.

Figure 2 (a) shows the cradle 1, 20.2, 21 and the cam plate 5゜2.
2 and 23 are shown in the standby state. When dispensing the product 8 in the second column, the camshaft 6 is rotated 90 degrees clockwise and the camshaft 19 is rotated 90 degrees counterclockwise as shown in FIG. 2(C).
°Rotate to engage the pedestal 2 and cam plate 5 and the pedestal 2
1 and the cam plate 23 are released, and the pedestals 2 and 21 are opened. After the product U1 falls, the camshaft 6.19
is returned to its original position and pedestals 2 and 21 are closed.

However, when both pedestals 2 and 21 are opened from the state shown in FIG. 2(a) to the state shown in FIG. 2(C), the motor M

27 as shown in FIG. 2(b).
The pedestal 2 located on the lower side with respect to the conveyance direction (direction toward the arrow) of 6 is opened before the pedestal 21 located on the upper side.

Since the pedestal 2 is opened before the pedestal 21 in this way, the product
The one closest to 3 will fall in a lowered position.

Here, let us consider a case where the pedestal 2 and the pedestal 21 are opened at the same time. In this case, normally the product 8 would fall on the table 15 in a straight position, and the product 8 would fall on the bar 17.
The rear part of the product is pushed and the product passes under the opened pedestal 2 shown in e and is transported toward the product takeout [113]. However, when the product is drinking water, the liquid adhering to the surface may dry during refrigeration in the stocker body 26 and become sticky. In this case, if the product ■1 sticks to ■2 and does not fall immediately even though the pedestal 2.21 is open, the product may fall onto the table 15 in an inclined position. be. In such a case, especially if the product 82 falls with its rear side down and its front side up, when the rear side of the item 82 is pushed by the bar 17, as shown by the imaginary line in FIG. In some cases, the product may become caught between the lower end of the open pedestal 2 and the table 15, resulting in defective delivery. In order to avoid this defective delivery, it is possible to make the distance 2 between the stocker body 26 and the table 15 sufficiently larger than that of the product 8, but as described above, the pedestal 2 can be changed to the pedestal 21J:
If the product is configured to be opened in advance, the front part of the product will fall lower than the rear part, as shown by the imaginary line 81, and the distance L2 will not be too large as described above. This also helps avoid defective product deliveries.

The same is true when dispensing the products 7 in the first column, and the pedestal 20 is opened before the pedestal 1.

FIGS. 3 and 4 show the motor M1. The open chain 11 question 27 of M2 and M3 and the drinking part waveform diagram of A are shown. 28, 29, and 30 are cam switches for detecting rotation angles of motors M+, M2, and M3, respectively, and are in contact with cams (not shown) mounted on camshafts 18, 5, and 19, respectively.

When the second column payout is instructed at time t2 in FIG. 4, the control device 27 determines the payout support column and
In the case of the column, a voltage with a polarity in the forward rotation direction is applied to the motor M2 from time t2, and a voltage with a polarity in the reverse direction is applied to the motor M3 at 1t-1 increments 3, which is a specified time T from time t2. Apply polar voltage.

When the cam switch 29 detects a 90° rotation of the camshaft 6, the power to the motor M2 is turned off, and when the cam switch 30 detects a 90° rotation of the camshaft 19, the power to the motor M3 is turned off at time t4. .

As a result, the pedestal 2.21 is opened and the dispensing of the product 1 is completed.Although FIG. One operation is completed by applying a voltage with a polarity in the normal rotation direction to the motor M3 and a voltage with a polarity in the forward rotation direction to the motor M3 until the camshaft 6.19 returns to the standby state.

Motor M1 immediately after time t1 in FIG. The energization waveform to M2 represents the selling operation of the first 21 rams.

Because of this configuration, products 7 and 8 are each placed on pedestal 1.
Since the products are supported by 20.2 and 21, the receiving area becomes larger compared to the conventional case in which product 7 was supported only by pedestal 1 and product 8 by pedestal 2, making it possible to support them more reliably. Become. In addition, it is divided into two pieces, 1J 3, cradle 1, 2012 and 2.
1 is adopted, compared to the case where pedestals 1' and 2' of 111- are used as shown in Fig. 10, the daple 5 is
Since the distance between L2 and L2 is as wide as Lo, the delivered product can be reliably conveyed to the product takeout port 13 even if the distance L2 is not sufficiently wide.

Furthermore, the pedestal 20 is opened before the pedestal 1, and the pedestal 20 is opened before the pedestal 1 is opened.
Because it opens before the pedestal 21, it is possible to control the falling posture of the product. It is possible to prevent the occurrence of a situation where the space is caught in between, and it is possible to reduce the distance L2.

In the above embodiment, since the first and second columns are arranged along the conveyance direction, the camshaft 6 and the camshaft 6
The drive motor, cam plate 5, cam body 11, etc. can be shared between the first column and the second column, contributing to cost reduction.

In the above example, the second product from the bottom is placed on the stocker wall 1.
2 to restrict the descent, but this was due to the force
Similarly to the area around the camshaft 6, the cam body 11 and the third stopper 9 that can be pushed out by the cam body 11 are also located at 18 and 19.
' or a fourth stopper 10' is provided as shown in the imaginary line in FIG. 1, and the product 74. i 1st and 3rd stopper 9.9
', the product 8 is held between the second and fourth stoppers 10.
Even if the fall of the 27th fi1-1 product is restricted by clamping it with 10', the same result as in 4 is obtained.

As explained above, in the product dispensing device of the present invention, the products in one column are supported by two pedestals, the first and second pedestals, so the receiving area is larger than before. In addition, since the pedestal is divided into two pieces, the first and second pedestals, even large items can be supported securely, so that the lower end of the open pedestal and the conveyance surface are easily connected. The interval Lo does not become narrower than when supported by a middle pedestal, and the product can be reliably dispensed to the outlet without making the height of the vending machine body higher than before. be.

Furthermore, in the present invention, the cradle on the lower side in the direction of conveyor transport behind the first and second pedestals is opened before the cradle on the upper side. Even if the tip of the pedestal on the lower side and the conveyor are brought close to the height of the product, the product can be reliably transferred to the take-out port, and the distance between the stocker body and the conveyor can be further narrowed.
