Description

Detailed Description of the Invention (Field of Industrial Application) The present invention allows food stored in a machine (mainly a range hood) to be machined without being heated by inserting coins or banknotes and operating a food selection button. The present invention relates to a microwave-equipped vending machine configured to eject food to the outside and to allow a purchaser to manually insert the ejected food into the microwave oven.

(Prior Art) In recent years, processed foods called range hoods that can be eaten by simply heating them in a microwave oven have become available, and these include a wide variety of foods, including red rice and bread. These processed foods not only have different packaging methods depending on the type, but also some that do not require any special modification when inserted into the microwave as they are taken out of the vending machine. There are various types of packaging containers, such as those that require opening the seal lid, which is a part of the packaging container, to add provided soups, condiments, etc.

Rather than being equipped with an automatic opening mechanism for microwave vending machines that sell a variety of range hoods, it is preferable to store the food selected by the purchaser in an unheated state. It would be better to configure the structure and control system so that the product is discharged outside the machine, and then the purchaser inserts it into the built-in microwave oven after manual assistance such as opening the seal lid and adding soup and condiments. This is preferable in terms of simplifying the process.

Such a vending machine with a microwave oven has already been proposed (see, for example, Japanese Utility Model Application Publication No. 113694/1983). This unit consists of a vending machine that discharges food in an unheated state, and a microwave oven that can be manually operated by the purchaser, combined into a shelf frame. There is.

(Problems to be Solved by the Invention) In the conventional microwave oven-equipped vending machine described above, the attached microwave oven can be operated arbitrarily. In other words, anyone can freely open and close the door of the vending machine, whether or not they purchase food from the vending machine, and can also freely perform heating operations. Therefore, in cases where constant monitoring is not possible, such as with vending machines installed on the street or in stores with few staff, items that were not sold at the vending machine or other foreign objects may be electronically detected. If the foreign object is inserted into the microwave and heated, it may be subjected to mischief.

The present invention has been devised in view of these circumstances, and even if the present invention is installed in a place that cannot be constantly monitored, it will not be subject to the above-mentioned mischief and will allow genuine food purchases to be made. The purpose of the present invention is to provide a practically advantageous vending machine with a microwave oven that can provide appropriate services to customers.

(Means for Solving the Problem) In order to achieve such an object, the present invention has the following features:
It has the following structure.

That is, the first invention discharges the food stored in the machine outside the machine in an unheated state by inserting coins/banknotes and operating the food selection button, and then transfers the discharged food to the equipped electronic A microwave oven-equipped vending machine configured to be inserted artificially into a microwave oven, including a microwave door lock device that locks the microwave oven door in a closed state at all times, and a door that detects the open/closed state of the microwave oven door. Equipped with an opening/closing detector and a barcode reader that optically reads the barcode attached to the food to indicate that it was sold in the vending machine when the food is inserted into the microwave oven. lock release means for releasing the range door lock device based on the input signal of the cooker and the operation signal of the food selection button; and determining whether or not a barcode pattern read by the barcode reader matches a determination reference pattern. and a microwave oven driving means for driving the microwave oven based on a matching signal from the pattern determining means and a detection signal from the open state to the closed state by the door opening/closing detector. That is.

In addition, the second invention allows food stored in the machine to be discharged from the machine in an unheated state by inserting coins or banknotes and operating a food selection button, and the discharged food to be stored in a built-in electronic A microwave oven-equipped vending machine configured to be inserted artificially into a microwave oven, including a microwave door lock device that locks the microwave oven door in a closed state at all times, and a door that detects the open/closed state of the microwave oven door. It is equipped with an opening/closing detector and a barcode reader that optically reads a barcode attached to food to indicate that it was sold in the vending machine when the food is not inserted into the microwave oven. A pattern determination means for determining whether or not a barcode pattern read by a code reader matches a determination reference pattern, based on a coin/banknote insertion signal, a food selection button operation signal, and a matching signal from the pattern determination means. and a microwave oven driving means that drives the microwave oven based on a detection signal from the door opening/closing detector that changes from an open state to a closed state. It is something to do.

(Function) The function of the above configuration of the first invention is as follows.

Since the microwave door is always closed by the microwave door lock device, items not sold by the vending machine or other foreign objects cannot be accidentally inserted into the microwave oven.

When the purchaser inserts coins or banknotes and operates the food selection button, the food is discharged from the machine in an unheated state. to release the range door locking device. Foods for which the seal lid has been opened or soup or condiments have been added by the purchaser are
The food is artificially inserted into a microwave oven by the purchaser, and at this time, the barcode pattern attached to the food is read by a barcode reader, and the pattern judgment means uses the read barcode pattern as the judgment standard. Determine whether it matches the pattern. If the food inserted into the microwave oven is food sold by the vending machine, the two patterns match and the pattern determination means outputs a match signal.

The microwave door is opened once when food is inserted into the microwave oven, and then closed after the food is inserted, and in response to this, the door opening/closing detector outputs a detection signal to change from the open state to the closed state. Then, the microwave oven driving means drives the microwave oven to heat-process the food based on the matching signal from the pattern determining means and the detection signal from the open state to the closed state.

However, when no matching signal is input, the microwave oven is not driven. That is, if the item inserted into the microwave oven is an item not sold in the vending machine or other foreign object, heat treatment is prohibited.

The effects of the above configuration of the second invention are as follows.

In this case, unlike the first invention, the lock of the range door cannot be released only by the input signal of coins/banknotes and the operation signal of the food selection button. Therefore,
At this stage, the oven door does not open, and the unheated food cannot be inserted into the microwave.

In this uninserted state, the purchaser causes a barcode reader to read the barcode pattern attached to the food product discharged outside the machine. When the pattern determining means determines that the read barcode pattern and the determination reference pattern match, a matching signal is output. Then, based on the input signal, the operation signal, and the coincidence signal, the lock release means releases the range door lock device.

In the same manner as above, when the purchaser inserts the food into the microwave oven after opening the seal lid and adding soup or condiments, and the oven door is closed, the door opening/closing detector changes from the open state to the closed state. A detection signal is output, and based on this, the microwave oven driving means drives the microwave oven to heat-process the food.

When a matching signal is not inputted by the pattern determining means, the microwave door locking device is not unlocked by the unlocking means, and therefore, as a result of mischief, items not sold at the vending machine or other foreign objects may be placed in the microwave oven. Insertion itself is prohibited. Of course, no heat treatment is performed either.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Note that, like a general vending machine, it is equipped with a means for counting inserted coins or banknotes, a means for calculating change, a means for discharging change, etc., but these are not directly related to the purpose of the present invention. Since it is not involved, its configuration is omitted. It will also be omitted in the explanation of the operation below.

Next, the operation of the microwave-equipped vending machine according to the first embodiment having the above configuration will be explained with reference to the flowchart shown in FIG.

After inserting coins or bills from the coin slot 3 or bill slot 4, the purchaser presses the food selection button 7 to select the desired food F. As a result, an insertion signal is sent from the coin/banknote insertion detection means 60 to the microcomputer 67, and the button operation detection means 61
An operation signal is sent to the microcomputer 67 from the microcomputer 67.

The microcomputer 67 has a feed signal input in step S1, and when the feed signal is input, the process advances to step S2 and waits for the input of the operation signal, and when the operation signal is input, the process proceeds to step S3 and the manipulated food is processed. Heat treatment time according to selection button 7
_T1 is set in the first timer 63, and in step S4, the food discharge device 62 is driven to discharge the selected food F from the storage to the takeout port 8 without being heated.

Next, in step S5, the microwave door lock device 2 is activated.
6, the motor 30 is reversely driven to swing the vertically swinging arm 28 upward, and the hook 27 is disengaged from the locking hole 32, thereby releasing the lock from the closed state of the range door 9. This step S5 corresponds to the lock release means in the configuration of the invention.

At step S6, it waits for the lock release signal to be input from micro switch _MS2 , and when it is input, it is determined that the lock has actually been released.
Proceed to the next step S7. In step S7, the motor 18 in the range door opening/closing drive mechanism 21 is driven in reverse, and the range door 9 is opened via the drive gear 20 and gear 17.
to open. Micro switch at step S8
It waits for the door open signal to be input from MS ₁ , and when it is input, it is determined that the range door 9 has actually been opened, and the process advances to step S9 to drive the bar code reader 33.

When the microwave door 9 is opened, the purchaser slides the food F on the slide surface 40 and places it on the turntable 22. When the food F slides on the slide surface 40, the barcode reader 33 reads the barcode 35 attached to the food F, and the reading pattern is stored in the reading pattern register 50.

The microcomputer 67 controls the pattern determining means 43 in step S10. As a result, the pattern determining means 43 reads out the reading pattern from the reading pattern register 50 and the determination reference pattern from the determination reference pattern register 51, compares the two patterns, and when they match, sends a matching signal to the microcomputer. 67, but if they do not match, a mismatch signal is sent.

The microcomputer 67 determines in step S11 whether the signal sent from the pattern determining means 43 is a matching signal or not, and if it is a non-matching signal, the microcomputer 67 jumps to step S25 (the subsequent operation will be described later).

If there is a match signal, the process advances to step S12 and the operation of the barcode reader 33 is stopped. Next, in step S13, the motor 18 in the range door opening/closing drive mechanism 21 is driven to rotate normally to close the range door 9.
In step S14, the system waits for the door close signal to be input from the micro switch _MS1 , and when it is input, it is determined that the range door 9 is actually closed, and the process advances to step S15, where the motor 30 in the range door lock device 26 is activated. The range door 9 is locked in the closed state by driving the range door 9 in normal rotation and locking the hook 27 of the vertically swinging arm 28 in the locking hole 32. In step S16, the microswitch _MS2 waits for a lock signal to be input, and when it is input, it is determined that locking has actually been performed and the process proceeds to the next step S17.

The first timer 63 is started in step S17, and the microwave oven driving means 66 is driven in step S18. As a result, the motor 24 is driven to rotate the turntable 22 on which the food F is placed, and at the same time, microwaves are emitted from the magnetron 65 and the food F is heated by induction. In step S19, the first timer 63 counts the heating treatment time _T1 and waits for the time to elapse. When the time elapses, the process proceeds to step S20 and the microwave oven driving means 66 is stopped. As a result, the heat treatment for the heat treatment time _T1 corresponding to the food F is completed.

Next, in step S21, the microwave door lock device 2 is activated.
6 to unlock the closed state of the range door 9, wait for the lock release signal to be input from the micro switch MS ₂ in step S22, and then proceed to step S22.
Proceeding to S23, the range door opening/closing drive mechanism 21 is controlled to open the range door 9. In step S24, the process waits for the door open signal to be input from the micro switch _MS1 , and the process proceeds to step S25, where the second timer 64 Start. The second timer 64 is activated in step S26.
Wait for the time to come up. Second timer 64
The purpose of the time count is to give the purchaser time to take out the heat-treated food F from the heating box 14.

When the second timer 64 times up, the process proceeds to step S27, drives the range door opening/closing drive mechanism 21 to close the range door 9, waits for the door close signal to be input from the micro switch _MS1 in step S28, and proceeds to step S29. Drive the advance range door locking device 26 to lock the range door 9 in the closed state, wait for a lock signal to be input from the micro switch MS ₂ in step S30, and when it is input, complete the series of operations. .

If the object inserted into the heating box 14 after the range door 9 is opened in step S7 is an article or other foreign object that was not sold in the vending machine, a discrepancy signal is generated in step S11. However, in this case, the process jumps to step S25, processes from step S25 to step S30 are executed, and the range door 9 is closed and locked. At this time, the microwave oven driving means 66 is not controlled and the inserted foreign object is not heated.

Second Embodiment The second embodiment relates to the second invention. FIG. 6 is a partially cutaway perspective view of the main part.

The food slide surface 40 is formed on the same surface as the front surface of the outer casing 10a of the microwave oven 10. In this embodiment, the barcode 35 of the unheated food F is read by the barcode reader 33, and the range door 9 is opened only when the read pattern matches the judgment reference pattern. This is because it is configured to release the lock.

Regarding the other configurations, the elements constituting the barcode reader 33, such as the laser tube 36, disk 37, reflector 39, and photoelectric conversion element 42, are tilted by 90 degrees compared to those of the first embodiment, and the microcomputer The second embodiment is the same as the first embodiment except that a third timer (not shown) is connected to 67.

Next, the operation of this second embodiment will be explained based on the flowchart of FIG.

The microcomputer 67 waits for the input of the input signal at step T1, and when the input signal is input, the microcomputer 67 proceeds to step T2 to wait for the input of the operation signal, and when the operation signal is input, it proceeds to step T3 and outputs the manipulated food. Heat treatment time according to selection button 7
_T1 is set in the first timer 63, and in step T4, the food discharge device 62 is driven to discharge the selected food F to the outlet 8. Then, in step T5, the barcode reader 33 is driven.

The purchaser slides the food F along the slide surface 40, but at this time, the barcode reader 3

control. As a result, the pattern determining means 43
reads the reading pattern from the reading pattern register 50 and the judgment reference pattern from the judgment reference pattern register 51, compares the two patterns, and if they match, sends a match signal to the microcomputer 67; If not, sends out a mismatch signal.

In step T7, the microcomputer 67 determines whether the signal sent from the pattern determining means 43 is a matching signal or not, and if it is a non-matching signal, ends all operations. That is, if the result read by the barcode reader 33 is an item that is not sold in the vending machine or other foreign matter, the operation of unlocking and opening the microwave door 9 is not performed.

If there is a match signal, the process advances to step T8 and the operation of the barcode reader 33 is stopped. Next, in step T9, the range door lock device 26 is controlled to unlock the range door 9 from the closed state. This step T9 corresponds to the lock release means in the configuration of the invention.

Wait for the lock release signal to be input from micro switch MS ₂ at step T10, and then proceed to step T11.
The process proceeds to step T12 to control the range door opening/closing drive mechanism 21 to open the range door 9, waits for the door open signal to be input from the micro switch _MS1 at step T13, and starts the third timer (not shown). ). During this process, the range door 9 is opened. That is, the range door 9 is opened only when the insertion of coins/bills, the operation of the food selection button 7, and the matching of patterns are all established.
Then, the purchaser places the food F on the turntable 22.

At step T18, the program waits for the lock signal to be input from the micro switch _MS2 , then proceeds to step T19, where the first timer 63 is started, and at step T20, the microwave oven drive means 66 is driven. As a result, the turntable 22 on which the food F is placed rotates, and at the same time, microwaves are emitted from the magnetron 65, and the food F is heated by induction. 1st at step T21
The timer 63 waits for the heating treatment time _T1 to expire, and when the timer expires, the process proceeds to step T22 and the microwave oven driving means 66 is stopped. As a result, the heat treatment for the heat treatment time _T1 corresponding to the food F is completed.

Next, in step T23, the microwave door lock device 2 is activated.
6 to unlock the closed state of the range door 9, wait for the lock release signal to be input from the micro switch MS ₂ at step T24, and proceed to step T24.
The program proceeds to T25, controls the range door opening/closing drive mechanism 21 to open the range door 9, waits for the door open signal to be input from the micro switch _MS1 in step T26, and proceeds to step T27 to start the second timer 64. let At step T28, wait for the second timer 64 to time up, then proceed to step T29, control the range door opening/closing drive mechanism 21 to close the range door 9, and at step T30, the door close signal is input from the micro switch _MS1 . Wait for the lock signal to be input from the micro switch MS ₂ at step T32, then proceed to step T31 to control the range door locking device 26 to lock the range door 9 in the closed state. Finish a series of actions.

In the above two embodiments, the range door 9 is automatically opened and closed by the range door opening/closing drive mechanism 21.

is energized, the locking rod 47 is moved out of the locking hole 48 against the elasticity of the spring 46, and the lock is released.

(Effects of the Invention) According to the first invention, since the oven door is always locked in the closed state, it is possible to prevent foreign objects from being inserted into the microwave oven by mischief, and it is possible to prevent coins and banknotes from being inserted into the microwave oven. The microwave door is unlocked by loading the food and operating the food selection button, but when the barcode pattern attached to the food is read by the barcode reader and this reading pattern matches the judgment standard pattern, the microwave door is unlocked. Since we would like to operate the microwave oven only to heat-process food and not operate the microwave oven at other times, we would like to avoid heat-treating items that are not sold in the vending machine or other foreign objects. can be prevented.

Further, according to the second invention, the microwave door is not unlocked only by inserting coins/banknotes and operating the food selection button, but by reading the barcode pattern attached to the food with a barcode reader. Since the microwave door is unlocked only when the reading pattern matches the judgment standard pattern, it is possible to prevent items that were not sold by the vending machine or other foreign objects from being inserted into the microwave. can be prevented.

Furthermore, in any of the present inventions, it is possible to automatically prevent unexpected heat treatment of foreign objects, so it is possible to automatically prevent unexpected heat treatment of foreign objects, so it is possible to avoid conditions that are difficult to monitor because vending machines are installed on the street or in stores with few staff. This helps prevent tampering and allows genuine food purchasers to provide proper service.
