Description

[Detailed Description of the Invention] The present invention relates to a cooking device for a vending machine for noodles, etc.

Generally, in this type of noodle vending machine, the main body is divided into a refrigerator compartment and a cooking compartment by a partition plate, and in particular, a food container containing noodles is stored in the latter by a conveying means from the refrigerator compartment. At the same time, hot water and stock can be poured into the food container from the hot water tank and stock container provided above the same cooking chamber, and the @ (food) in the food container is cooked and the food is sold at the food outlet (
(not shown), but in conventional vending machines, the cooking device simply adds hot water and stock to the food container, so the food is not sold. The noodles were not very warm and lost their flavor.

In addition, recently, in view of this point, a vending machine equipped with a mechanism for blanching the noodles inside the food container has been announced, but the structure of these machines is extremely complicated. There was a need for improvement because it took a long time to boil the water, resulting in low cost and time saving as a vending machine.

The present invention has been devised in view of such conventional circumstances, and one embodiment thereof will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic perspective view showing the internal structure of a noodle vending machine equipped with the cooking device of the present invention. 4 is a cooking device according to the present invention which will be described later; 5 is a conveying device for transporting food containers containing food from the refrigerator compartment IA to the cooking device; 6 and 7 are food containers in the cooking device; This is a hot water storage tank and a stock container provided for injecting hot water and stock into the container via electromagnetic valves 8 and 9 when it is transported.

While the vending machine is generally constructed as described above, the cooking device 4 will be explained in more detail below.

That is, FIG. 1 and FIG. 2A show the device 4.

At the mouth, reference numeral 10 denotes a loading port (not shown, but a guide plate 12 and a guide roller 13 are provided at the lower edge) into which the food container 11 sent from the conveying device 5 is received;

This is a device case having a transport port 14 which is always closed by a door 15 pivoted on the upper edge, and a wall member 10a of the case 10 which has a transport port 14 and which pivotally supports this door 15. In order to facilitate cleaning inside the case 10, it is pivoted at the lower edge and can be opened and closed.

(When opened, it looks like the two-dot chain line in Figure 2 A).

Reference numeral 16 denotes a pouring vibro a and a stock pipe 7a coming out of the hot water storage tank 6 and stock container 7, and brings them together to face the inside of the top plate of the device case 10.On the other hand, a pouring tool 17 is located inside the case 10. A truncated conical filter 18 facing into the bottom plate and having a large number of small holes on the side surface is provided at its tip.

Note that the filter 18 is open at its upper and lower ends.

Also, within the device 10... is stored.

1. Inside the device case 10, there is a bearing plate 19 on which the food container 11 carried through the loading port is placed, and a bearing 20 is fixed to the lower surface of the receiving plate 19, as shown in FIGS. 3 to 5. The rotating and swinging shaft 21 is fixed at one end to a tape portion 22a of a boss member 22 fixed to the tip of the motor shaft 23. .

Reference numeral 24 denotes a container support plate fixed horizontally on a support 25.25 attached to the edge of the receiving plate 19 on the side far from the loading port, and is large enough to cover approximately half of the receiving plate 19. There are many holes 24a on the board surface.

...... is drilled.

The motor shaft 23 is linked via a speed reduction mechanism 28 to a swing motor 27 which is a component of a drive source 26 (provided outside the device case 10) for rotating and swinging the receiving plate 19. A drive gear 29 is fixed in the middle of the shaft path.

30 has dimensions sufficiently larger in diameter and width than this drive gear 29, as shown in FIG. It is a partially toothed gear in which the teeth between A and A are omitted 31, and is fixed to a rotating shaft 32 which is appropriately pivoted.

33 is a cam plate similarly fixed to the rotating shaft 32,
The cam surface has a slightly larger circular arc interval than the toothless portion 31 of the toothless gear 30, and its radius of curvature is larger than the diameter of the toothless gear 30.

Reference numeral 34 denotes a gear for discharging hot water fixed to a rotating shaft 38 which is appropriately pivoted, and is provided corresponding to the situation where the toothless portion 31 of the toothless gear 30 is present.

36 is a rotation control plate similarly fixed to the rotating shaft 38, and is larger than the disk 37 with a diameter equal to the diameter including the tooth height of the discharging gear 34, with approximately 90° removed. , then,
When the pointed contact parts 37a, 37a of this cutout part 37 come into sliding contact with the cam surface of the cam plate 33, the discharging gear 34 comes into sliding contact with the toothless part 31 of the toothless gear 30, and some rotational force is generated. Even if the above-mentioned point 37a is given a
If the rotation of the cam plate 33 progresses and the pointed abutting parts 37a, 37a no longer come into sliding contact with the cam plate 33, the discharging gear 34 will separate from the toothless part 31 and the toothless gear 30 will move away from the toothless gear 30. When engaged with the teeth, the water discharge gear 34 is configured to rotate as shown in FIG. 6.

39 is a hot water drain lever fixed to the upper rotating shaft 38,
A sliding pin 40 is fixed to the tip of the sliding pin 4.
0 is slidably inserted into a sliding groove 42 of a U-shaped guide 41 attached to the receiving plate 19.

The above is a mechanism for causing the food container 11 placed on the receiving plate 19 in the cooking device 4 to rotate and oscillate and drain the water, as will be described later in the section on the function of the receiving plate. , Next, the food container 1 in which the noodles are blanched by the action of this mechanism.
1 will be explained below.

In FIG. 7, reference numeral 43 denotes an unloading board fixed or appropriately equipped on the back surface of the device case 10, with an unloading motor 44 on the negative side, and a rotating shaft of the motor 44 on the other side. a crank 45 fixed to the crank 45; a connector 47 pivotally supported in the middle of a first pivot lever 46 having one end pivoted thereto and the other end pivotally supported on the other surface of the carry-out board; A connecting lever 49 is disposed at the other end of the first pivoting lever 46, and the other end of the second pivoting lever 48 is pivoted at one end thereof, and the other end of the second pivoting lever 48 is pivotally supported on the other surface of the unloading board. The other end of the connecting lever 49 is pivotally supported by the end of an extrusion rod 50 which is slidably inserted into the device case 10 from the back side of the case 10 with a guide 51. The unloading mechanism is constructed in the following manner.

The present invention is constructed as described above, and its operating state will be explained below.

When a predetermined coin is inserted into the coin slot (not shown), a sales signal is output accordingly.
One food container (noodles stored inside) 11 stored in the refrigerator compartment IA is carried into the device case 10 as shown in FIG. When the food container 11 is placed on the top (as shown in FIG. 8 (1-A) and (1-B)), approximately half of the top surface of the food container 11 is covered and supported by the container support plate 24 on the receiving plate 19. It is being

) A detection switch (not shown) installed as appropriate detects this and transmits the detection signal to a cooking time setting timer (not shown)
Based on this, the timer is applied to the swing motor 2.
The motor 27 starts outputting a signal to the motor 7 and causes the motor 27 to go sideways.

Then, since the motor shaft 23 is rotated in the direction of the arrow A, the rotary swing shaft 21 rotates about the center approximately on its axis as shown in FIG. The food container 11 together with the plate 19 is shown in FIGS.
The hot water into which the noodles in the food container 11 are poured (the food container 11
Just before the start of rocking, the electromagnetic valve 8 is energized and the hot water tank 6
The food is blanched using hot water poured into the food container 11.

On the other hand, immediately before the receiving plate 19 is rotated and swung, the relationship between the toothless gear 30 and the hot water discharge gear 34 is such that the hot water discharge gear 34 is sliding on the starting end of the toothless portion 31 of the toothless gear 30. At the same time, the contact portion 37 of the rotation control plate 36 contacts the cam plate 33.
Since a and 37a are in contact with each other, even if the toothless gear 30 is rotated as the motor shaft 23 and drive gear 29 are rotated, the hot water discharge gear 34 is not rotated.

However, the rotation of the partially toothed gear 30 in the direction of arrow B (
(See Fig. 6 A for the rotational state) progresses, and the above-mentioned hot water discharge gear 34
When the contact portions 37a, 37a come to mesh with the teeth of the partially toothed gear 30 and the contact portions 37a, 37a separate from the cam plate 33, the hot water discharge gear 34 starts rotating in the direction of the arrow C.
Accordingly, the hot water discharge lever 39 moves the sliding pin 40, which has also been rotated in the direction of arrow C, into the sliding groove portion 42 of the U-shaped guide 41.
By sliding the inside of the food container 11, the food container 11 and the receiving plate 19 are tilted approximately 45 degrees so that the container supporting plate 24 is downward as shown in FIGS. and drain the water.

Incidentally, the rotation and rocking of the receiving plate 19 is continued even during this time of discharging hot water.

When this discharge operation is completed, that is, when the gear 34 for discharging hot water comes into sliding contact with the toothless portion 31 again and the abutting portions 37a, 37a come into contact with the cam plate 33, the discharging The rotation of the gear 34 is stopped, and the food container 1
1 is again rotated and oscillated together with the receiving plate 19 as shown in FIG. After blanching the noodles, the blanching process and the draining process proceed until the swinging motor 27 stops, and when the motor 27 stops, all movement of the food container 11 stops. When this is detected, both the electromagnetic valves 8 and 9 are opened, and an appropriate amount of hot water and stock are poured into the food container 11.

Then, when the injection of hot water and stock is completed, a switch means (not shown) that detects this prompts the drive of the carry-out motor 44.

Immediately before the motor 44 is driven, the connection point P1 between the crank 45 and the connector 47 is at P1', and the connection point P2 between the connection lever 49 and the push rod 50 is at P2', so the tip of the push rod 50 is located at 13 points in the figure.

Therefore, since the crank 45 is rotated in the direction of the arrow as the unloading motor 44 is driven, this rotational force is applied to the push rod 50 in the direction of the arrow through the connector 47, the first pivot lever 46, and the connecting lever 49. The food container 11 placed on the receiving plate 19 by sliding in the E direction as shown in FIG.
to the vending outlet of the vending machine.

At this time, the tip of the pushing rod 50 reaches point P3', and the 11 points of the crank 45 reach point P.

After that, the crank 45 continues to rotate in the direction of the arrow, but after the crank 45 passes the point P'', the connector 47, the first pivot lever 46, and the connecting lever 49 etc., slide the extrusion rod 50 in the opposite direction of the arrow,
When the tip of the push rod 50 returns to the 13 points, the drive of the carry-out motor 44 is stopped.

This marks the end of one sales process.

As a result of repeated sales, it is necessary to remove the dregs of ingredients etc. in the device case 10, as shown in Fig. 2. By opening it as shown by the two-dot chain line in A, the dregs remaining inside the device case 10 can be easily removed.

The cooking apparatus of the present invention is constructed as described above, but in the case where the swing motor 27 and the unloading motor 44 are operating, that is, when there is a power outage during cooking, the present invention further describes the following. We have prepared countermeasures such as:

The circuit shown in FIG. 11 is the circuit, and as mentioned above, during normal operation, the food container 11 is placed on the receiving plate 19, and the first relay R1 is self-held by the switch SW1 that detects this. The first timer T1 is energized through the ON relay contact R□-1 and the normally closed relay contact R2-1. The swinging motor 27 is driven to rotate and swing the food container 11 together with the receiving plate 19, and the swinging motor 27 is driven to turn the first double-throw switch S.
W2 switches its movable terminal to fixed terminal S□,
The second relay R2 and the second timer T2 are energized.

In this state, if a power outage occurs, the first relay R
However, when the power is turned on again, the movable terminal of the switch SW2 switches to the fixed terminal S1 as described above, so that the power is turned off to the second relay R2. Therefore, the swinging motor 27 is energized through the relay contact R2-1, and the receiving plate 19 rotates and swings from the state immediately before the power outage to cook the noodles and carry out the food container.

Separately, if the power is cut off while the food container is being taken out after the cooking process has finished, all relays other than the third relay R3 have already been reset when energized; Only the third relay R3 is connected, and the unloading motor 44 has a relay contact R3-1.
Since electricity is supplied through In order to do this, the relay contact R3-□ connected in series to the unloading motor 44 is also turned off, so the motor 44 is stopped.

Since the present invention is constructed as described above, the receiving plate is made to perform a simple rocking motion and a tilting motion, so that the surface inside the container is fully exposed to the hot water during the rocking motion and is warmed. Therefore, this is an excellent idea that allows the noodles to be sold at a temperature that is warm enough to be eaten.
