Description

Vending machine for automatic cup jamming in cup chute

In general, in this type of cup vending machine, the beverage tank is arranged at the upper position in the vending machine, and the cup is placed at the lower part to inject the beverage to sell.

Moreover, in the conventional cup type | mold vending machine, since the cup in which the drink was injected is made to open a transparent door, and the drink injecting cup is taken out, the sales outlet which takes out the cup was in the low position. For this reason, the customer has to bend the waist and take out the cup containing the drink, which is inconvenient to be forced into a poor posture.

In addition, there was a hassle to open the door with one hand and take it out with the other.

In addition, since the cup is held by the elastic cup gripping member in the sales area, it is not easy to pull it out from the gripping member with one hand, and when the cup is taken out, the drink in the cup is sometimes caught up and the cup gripping member is dirty. As a result, there was a problem of becoming unsanitary.

An object of the present invention is to automatically release a cup jam when there is a jam in the cup chute.

MEANS TO SOLVE THE PROBLEM In order to achieve the objective mentioned above, this invention is the cup-type automatic vending machine which injects and sells the drink in the cup discharged from a cup supply apparatus based on a sale operation start, The cup discharge outlet provided in the main body front part, The said cup A sales door for opening and closing the dispensing outlet, and a cup conveying means for transferring the cup, which has been injected with the beverage in the vending machine body, from the beverage dispensing position to the cup dispensing outlet and being sent from the cup dispensing outlet to the outside of the vending machine body. A vending machine for automatically releasing cup jams in a cup chute, characterized in that is provided.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing the overall appearance of a cup-type vending machine according to the present invention. The selling unit 1 is constituted by a counter table type that is wide open horizontally, unlike a conventional rectangular vending machine.

A part of this counter table part 2 is formed in a dome shape, and a cup discharge port for carrying out goods is provided in the counter table part 2, while a dome shape of the same shape is approached under this dome part. The sales door 3 is provided so that the rotational movement is free, and the sales door 3 is formed with a hole that coincides with the cup outlet when the sales door 3 is opened.

Therefore, normally, the said cup delivery opening by this sales door 3 is comprised so that it may open by mutually matching holes at the time of sale.

Moreover, the selling part 1 is provided in the position of the height one step higher than the position of the conventional height.

Specifically, this selling part 4A is formed just below the operation panel 4 to which the selection button 4A is attached, and is in a recessed state, and has a height that does not interfere with the extraction of the cup 6. Open sideways with the dimensions of.

And this cup part is comprised so that the drink-injected cup may spring out.

On the other hand, the supply unit to which cups, beverages, ice, etc. are sent out is installed in a vending machine.

Next, the structure of a main part is demonstrated to the cup type | mold vending machine of this invention based on FIG.

2 is a configuration diagram showing a situation in which the cup is injected and the cup after the injection to move the cup up and down conveying device, and FIG. 3 is a configuration diagram showing a situation in which the cup containing the drink rises by the cup up and down conveying device. In addition, Figure 4 is a block diagram showing a situation in which a cup containing a drink approaching the sales department.

In each figure, (5) has the opening-and-closing cup holding member 7A (7B) which hold | grips the cup 6 sent out from the cup supply apparatus as mentioned later by a sales instruction, and also conveys a cup. As a cup holding device which also acts as a device, the cup holding device 5 is installed so as to slide the slider portion 9 freely on a rail 8 which is installed almost horizontally in a cabinet of the vending machine. It is comprised so that it may slide along the rail 8 in the front-back direction seen from the front.

By the way, although not shown in the upper position shown in FIG. 2 in which the cup holding apparatus 5 is normally waiting, the beverage supply apparatus, the ice maker, etc. are provided, and the beverage injection nozzle 10 and ice from them are provided. The discharge hose 11 faces the cup 6.

In addition, the beverage supply apparatus combines the beverages in accordance with the product selection operation by the consumer as described below, and combines the beverages in the state in which the cup holding device 5 holds the cup 6. Inject into the cup (6) through.

At this time, the beverage supply device dilutes the syrup with carbonated water to combine the carbonated beverage or dissolve powder raw materials such as coffee with hot water, and combines the coffee beverage by adding sugar and milk as necessary.

Similarly, the ice maker also sends ice into the cup held by the cup holding device 5 through the ice discharge hose 11 when there is a product selection operation by the consumer.

When both the drink and the ice are supplied to the cup, the cup holding device 5 slides in the direction of the arrow A as shown in FIG. 2, advances to the position shown in FIG. 3, and stops at the predetermined position.

The control regarding the stop of the cup holding apparatus 5 is controlled by the optical position sensor etc. arrange | positioned on the conveyance path of a cup.

4 shows a situation where the cup 6 has emerged above the counter table portion 2 of the sales section 1, and as can be seen from this figure, the cup 6 containing the beverage is raised from the bottom to the sales section. It appears in (1).

For this reason, the sales door 3 opens and the cup dispensing opening 22 which the cup 6 exits is opened.

As described above, gripping of the cup discharged from the cup supply device → injecting beverage into the cup → after pouring the drink, moving to the cup up / down conveying device → transferring the cup to the cup up / down conveying device → lifting the cup → to the sales department The cup beverage is provided to the consumer by performing a series of sales operations called the export of.

Next, the operation of the vending machine in the configuration of the present invention will be described.

The cup holding members 7A and 7B of the cup holding apparatus 5 are held in accordance with the large cups and small cups to be sold, and the upper and lower sides of the cup holding member 30 are held at a position where the cup holder 30 can be held.

When a predetermined coin is put in and a sale command is given by the consumer's selection operation, the cam released from the cup supply device is held by the cup holding device 5 through the cup chute 24.

When caught in the cup chute 24 or when the cup is jammed or inclined at the place of the cup holding device 5, the cup detection sensor S detects the state and stops selling or slightly opens the cup gripping members 7A and 7B. Secure the gripping correctly.

After the cam drive device 45 is started and held a little, the cup 6 displaces and approaches the beverage injection nozzle 10 side, and the cup holding ice or beverage supplied from the ice maker and the beverage supply device at that position. (6) takes a drink injection is made.

After the drink is injected, it is moved to the cup up / down conveying device 12 side by the drive device 9A.

When the coaster part 18 of the cup up-and-down conveying apparatus 12 raises in the position which completed the movement, and receives the bottom surface of the cup 6, and puts it on it, the cam drive device 45 will operate again and the cup will operate. The holding member 7A, 7B is moved up by the cam drive device 45 again after the transfer, and the cup holding member 7A, 7B is opened and the cup 6 is conveyed toward the coaster portion 18.

After the cup holding member 7A and 7B transfer, the cup up-and-down conveying apparatus 12 raises again and the coaster part 18 raises, and returns to an original position, and awaits next sale.

Since the sales door 3 is already open and the cup dispensing opening 22 is open during the rise of the coaster part 18, the cup 6 is placed on the coaster part 18 so that the sales part 1 It comes out from under the center of.

After taking out the cup 6, the coaster part 18 descends to an original position, waits for the next cup transfer, and completes a series of selling operations.

In addition, in the event of an abnormality such as a power failure in the course of the horizontal movement or the upward movement of the cup after the injection of the drink, the cup containing the drink is forcibly moved to the cup disposal position after the return, and the cup is dropped as it is. Discard it.

Next, the abnormality which arises until the cup 6 discharged | emitted from the cup dropping apparatus 23 is gripped by cup holding member 7A (7B) is demonstrated.

As such an abnormality, the following cases can be considered. First, the cup does not come out at all. Second, the cup was jammed in the cup chute. Third, the cup was caught in the cup holder. Fourth, the cup was not held correctly and the drink did not enter the cup well due to the inclination or protrusion.

The above situation as described above is schematically illustrated in FIG.

As shown in FIG. 5, the jam (cup of cup) in the cup chute 24, the jam (cup of c) on the cup holding part 7, and the inclination (cup of d in the cup holding part 7). Abnormalities can occur. If there is no such abnormality, the cup in the cup holding part 7 is gripped correctly in an upright state (cup of a).

In order to find out the cause of these abnormalities, in this invention, the cup detection sensor S is installed in the just upper part of the position which keeps the cup which fell from the cup dropping apparatus 23 normal, and by this sensor, 1st, a cup is dropped, and 2nd. In addition, it is possible to identify the cause of the failure by identifying the holding position of the cup and thirdly, the location of the cup jamming.

As the cup detection sensor S, a transmissive optical sensor is used, and the other detection output obtained by whether the light from the light emission part Sa permeate | transmits or light-shields to the light receiving part Sb is judged by processing.

6 is a flowchart thereof.

This figure shows a light-transmitting state in which light reaches the light-receiving unit Sb when the cup detection sensor S is turned on in the flowchart, and a light-shielding state in which light does not reach the light-receiving unit Sb when the sensor S is turned off.

After the cup is sent out, the sensor S is driven (process 51), and the light is emitted to pass through the light-receiving unit Sb, or the light is blocked.

In other words, it is determined whether the sensor is ON (judgment 52), and if it is OFF that does not turn ON, it is checked whether the state continues for 0.4 seconds (judgment 53). That is, when judgment 52 is NO (the sensor is not turned ON) and judgment 53 is YES (it is OFF for 0.4 seconds), it is clearly determined that the sensor S itself is abnormal or an abnormal state in which foreign matter is caught between the sensors. do. In this case, therefore, the sale is stopped (process 54).

If judgment 52 is YES, the sensor is normal, and then the next time the sensor is turned off (judge 55), if it is OFF, then judgment 58 is executed; if it is not OFF, the ON state continues for 1 second. Look at it (Judg 56).

If the cup normally passes the sensor S, the sensor is turned off and the decision 55 is YES. However, if judgment 55 is NO and the sensor is not turned off and the sensor is in the ON state for one second, if the judgment 56 is YES, the cup will be dispensed but will not fall to the place where the sensor is present even after 1 second or more has elapsed. In addition, it is judged that there is an abnormal state in one of two ways, whether it is caught in the middle of the cup passage or the cup is not discharged at all.

Therefore, also in this case, a sale is stopped (process 57).

Here, the limit for one second is that if the normal drop state, the cup will pass through the sensor S within one second, and if the jam is released even if caught in the middle and reaches within one second, it is determined as a normal fall.

If Decision 55 is YES, the next time it is checked whether the sensor is ON again (Decision 58), and if the sensor is not ON, it is checked whether the OFF state is continuing for 1 second ( Decision 59).

When judgment 55 and judgment 58 are YES, respectively, it is judged that the cup falls normally and is held by the cup holding part 7 normally.

That is, the sensor is turned off while the cup 6 passes through the sensor S, and the sensor is turned on as the passage ends. Thus, the inverted output is obtained from the sensor as off and on.

Therefore, in this case, since the cup 6 is normally held by the cup holding members 7A and 7B, it is sufficient to inject the beverage, so that the beverage sales are performed after the sensor drive stationary (process 61) is performed (process 62). ).

However, the situation where the judgment 58 is NO and the judgment 59 is YES means that the cup 6 has not completely passed the sensor S. That is, unless the cup 6 is caught and shielded from the upper part of the cup holding part 7, or the cup 6 is inclined and it is not correctly held by the cup holding part 7, it is a situation. In this case, therefore, the sale is stopped (process 60).

Here, the thing limited to 1 second is that even if there is a jam of a cup or the inclination of a cup in the place of the cup holding part 7, if the state is naturally changed within 1 second and a normal grip is performed, a drink sale can be performed. To determine.

As described above, in addition to performing a determination as to whether or not the cup is normally released, if an abnormality exists, it becomes possible to identify the abnormal place, and the subsequent response can be performed appropriately and quickly. .

In addition, the bottom surface of the cup 6 discharged safely from the cup dropping apparatus 23 to the cup holding members 7A and 7B is supported by the cup stand 30.

On the other hand, the cup support 30 freely raises and lowers, so that the heights of the cups can be aligned side by side according to the size of the designated cups.

In addition, cups of different sizes are discharged from the cup dropping devices 23A to 23C, respectively.

As mentioned above, although the detection method of the catching position of a cup was demonstrated, the jamming of the cup in the cup holding part 7 can detect this and return to a normal state in the next procedure.

As shown in FIG. 7, when the cup 6 coming out of the cup chute 24 does not enter the cup holding members 7A and 7B correctly, the cup 6 is continuously shielded and the signal from the cup detecting sensor S is in a constant state. . Therefore, in the case of this cup latching state, the cup holding members 7A and 7B are opened as shown in FIG.

That is, the cam 42 is rotated so that the protrusions 41A and 41B abut against the cam surface 44b.

As a result, the cup 6 is placed between the cup pedestals 30 in the normal posture of the solid line from the jamming state of the cup shown by the dashed-dotted line, and is in the upright state by the cup holding members 7A and 7B again. It is held in a posture, after which the beverage is infused.

The above control operation is shown in FIG.

In the flowchart of this figure, when the sensor S is turned on, light is transmitted to the light receiving part Sb, and when the sensor S is turned off, the light is not lighted to the light receiving part Sb.

After the cup is sent out, the cup detection sensor S determines whether or not a state change occurs in the OFF-ON state (decision 71).

If it falls normally, once the light is shielded and the sensor is turned OFF, and then the light is immediately transmitted, the sensor is turned ON, and the judgment 71 is YES, where the inclination or jamming of the cup in the cup holding device 5 exists. It seems to be. Therefore, in this case, a cup holding operation is performed to the cup holding apparatus 5 which was waiting (process 72), and then drink sales are performed (process 73).

If judgment 71 is NO and the sensor S does not turn on even after 1 second has passed (judgment 74), and if judgment 74 is YES, the cup 6 is caught by the cup gripping members 7A and 7B. It is in a state where it is not gripped normally. Therefore, in this case, the presence or absence of the flag is checked (decision 75), the flag is set because there is no flag (process 76), and the cup holding device 5 is then changed from the standby state to the open state (process 77). . As a result, the dropping of the hanging cup 6 is possible again, and the dropping of the cup 6 is carried out in a vertical posture and positioned on the cup stand 30.

The cup gripping apparatus 5 is then returned to the standby state for accommodating the cup (process 78).

Subsequently, after the process 78, the judgment 71 is again performed, and if the cup 6 is normally held by the above-described process 79, the judgment 71 is YES, and the process 72 is performed to sell the beverage in the process 73.

However, in the case where the cup 6 is jammed despite the processing 77, the judgment 71 is turned ON again, and the judgment 74 is also YES, and the judgment 75 is YES because the flag is set in the judgment 75. Then, the sale is stopped (process 79).

Next, a description will be given of a solution in the case where the cup is blocked by the syrup on the inner surface of the cup chute 24 and cannot fall off.

The cup vending machine is also capable of supplying carbonated beverages, and is equipped with a carbonater and a carbon dioxide bomb for producing carbonated water. Therefore, if the cup 6 passes through the cup detection sensor S and is shielded within a predetermined time after the cup is sent out, a detection pulse is generated within that time. However, even if a predetermined time passes, the light shielding state does not occur, and if the detection pulse does not occur, it is expected that the cup 6 does not fall and is caught in the cup chute 24. In this case, therefore, the carbon dioxide gas CO ₂ is blown out of the carbon dioxide gas nozzle 80 to forcibly exclude the cup 6 hanging in the cup chute 24.

According to the configuration and function of the vending machine for automatic cup jamming in the cup chute according to the present invention described above, when there is a cup jam in the cup chute, the carbon dioxide gas is ejected from the carbon dioxide gas nozzle into the chute and the cup jamming. Can be automatically released.
