Description

  The present invention relates to a vending machine that heats and sells beverage products containing milk.

  Generally, a vending machine that sells warmed products has a structure in which the entire product storage for storing products is heated, and the entire stored products are in a standby state. However, this has a problem that products that have a relatively short quality deterioration time, such as products containing milk, increase the number of products that reach the quality deterioration time before sale and increase the number of discarded products.

  In order to solve such problems, a vending machine described in Japanese Patent Application Laid-Open No. 2000-57431 has been proposed.

  The vending machine described in this gazette divides the product storage into two parts, the upper part and the lower part of the storage part and the sales part, and the upper storage part stores the goods at room temperature while heating the goods in the lower sales part It is structured to heat with the device. And when a warmed product is sold from the sales department, the store part is replenished with the normal temperature goods by that much, and the situation where the goods are heated for a long time is avoided.

This vending machine constantly measures the residence time of the product in the sales department. When the warming residence time reaches the product deterioration time, the vending machine stops selling the deteriorated product and discards the deteriorated product. It can be done.

  A schematic structure of a vending machine 1 according to the present embodiment will be described with reference to FIG. The vending machine 1 can sell both cold products and hot products, but for the purpose of explaining the features of the present invention, only the location for storing hot products is shown in FIG.

  The vending machine 1 has a machine room 2 in which a cooling device or the like (not shown) is installed. A hot product (for example, a product containing milk) (hereinafter referred to as a product) G is stored above the machine room 2. And a product storage chamber 3 for heating.

  The product storage chamber 3 is divided into upper and lower parts, and has a storage unit 31 for storing the product G in the upper part and a sales unit 32 for selling the product G in the lower part.

  The storage unit 31 is formed by arranging the circular arc guide plates 311 in a zigzag manner so as to face each other, and forms a sales commodity passage 312 that meanders up and down between the opposing circular arc guide plates 311. Such product passages 312 are arranged in three rows in the front-rear direction of the product storage chamber 3. A product input plate 313 is provided above each product passage 312 so that the product G is guided to each product passage 312 when the product is filled. On the other hand, a stored product carry-out device 314 is installed below each product passage 312. Each stored product carry-out device 314 holds the lowest product G1 and similarly releases the hold state of the product G1 so that it can be dropped and carried out downward.

  In the sales section 32, arc guide plates 321 are arranged in a zigzag pattern so as to oppose each other, and a sales merchandise passage 322 that meanders up and down is formed between the arc guide plates 321 facing each other. Such merchandise passages 322 are arranged in three rows in the front-rear direction of the merchandise storage chamber 3, and are arranged so as to face the respective merchandise paths 312 of the storage unit 31 in the vertical direction. A sale merchandise carry-out device 324 is installed below each merchandise passage 322. The sale merchandise carry-out device 324 holds the lowest-order merchandise G2, and similarly releases the hold state of the merchandise G2 so that it can be dropped and carried out downward.

  A heat-insulating openable and closable damper 33 is installed between the storage unit 31 and the sales unit 32 configured as described above, that is, below each stored product carry-out device 314. Each damper 33 functions to suppress heat exchange between the storage unit 31 and the sales unit 32 as much as possible by partitioning the storage unit 31 and the sales unit 32 up and down.

  Further, a chute plate 4 that rolls and conveys the product G dropped from the sales unit 32 forward is installed below the sales unit 32, and the product G is guided to the product takeout port 5 through the chute plate 4. ing. On the back side of the chute plate 4, an internal circulation fan 6 and a heating device 7 are installed. The air heated by the heating device 7 by driving the internal circulation fan 6 is circulated in the sales section 32.

  In the vending machine 1 configured as described above, the quality control of the product G is performed by the drive control circuit shown in FIG. That is, the vending machine 1 is controlled by a microcomputer (hereinafter referred to as a microcomputer) 10. The microcomputer 10 has a CPU 101, a timer 102, and a memory 103. CPU 101 receives output signals from storage unit lowest product detector 11, product selection button 12, sales unit highest product detector 13, warning carry-out switch 14, deterioration carry-out switch 15, and stop switch 16. Based on these signals, the CPU 101 drives and controls the stored product carry-out device 314, the sales product carry-out device 324, the quality warning lamp (warning product display means) 17, and the quality deterioration lamp (deteriorated product display means) 18.

  Here, the memory 103 stores a product code attached to the lowest product G1 in the storage unit 31 as needed. The memory 103 stores a quality deterioration time T1 and a quality warning time T2. The quality deterioration time T1 is a residence time in which the product quality deteriorates in the heated product G. On the other hand, the quality warning time T2 is a time in which the product G approaches the quality deterioration time T1, that is, the product G is quality in a short time thereafter. This is the residence time that reaches the deterioration time T1. The timer 102 measures the residence time T of the product G and the detection times of the product detectors 11 and 13. The quality deterioration time T1 and the quality warning time T2 are stored in days. For example, the quality deterioration time T1 is stored as 14 days, and the quality warning time T2 is stored as 10 days. It can be changed arbitrarily with a remote control operated by. In consideration of the case where products that do not require quality management control are accommodated, the quality deterioration control and the quality warning control can be canceled by setting each time T1, T2 to “0 days”.

  The storage unit lowest product detector 11 detects the lowest product G 1 in the storage unit 31, and the sales unit top product detector 13 is stored in the top product (product passage 322) of the sales unit 31. The product (G3) located at the highest possible position) is detected. As the detectors 11 and 13, as long as the products G1 and G3 can be detected, not only an optical element such as a photoelectric switch but also a microswitch or the like may be used.

  As shown in FIG. 2, the warning carry-out switch 14, the deterioration carry-out switch 15, the stop switch 16, the quality warning lamp 17 and the quality deterioration lamp 18 are, for example, deteriorated products installed on the door inside the vending machine 1, etc. The warning board 19 is provided. Here, a plurality of quality warning lamps 17 and quality deterioration lamps 18 are installed so as to correspond to the product passages 312 of each column, and warning and deterioration are notified by lighting of the lamps 17 and 18.

  The warning carry-out switch 14 is a switch that outputs a carry-out command so as to carry out the product that has reached the quality warning time T2, and the deterioration carry-out switch 15 outputs a carry-out command so as to carry out the product that has reached the quality deterioration time T1. Switch.

  Hereinafter, the quality management control of the product G of the vending machine 1 according to the present embodiment will be described. As shown in FIG. 4, the quality management control includes stored commodity carry-out control (S1), warning / deterioration determination control (S2), and quality countermeasure control (S3). Here, the stored product carry-out control performs product carry-out control from the storage unit 31 to the sales unit 32, and the like. The warning / deterioration determination control determines whether or not the quality of the product G has deteriorated and whether or not the quality of the product G is in a state to be warned, and displays the status of the product G on the lamps 17 and 18. The control which performs is performed. In the quality countermeasure control, when there is a warning product G or a deteriorated product G, control is performed to carry it out to the outside.

  First, stored goods carry-out control will be described with reference to FIG. In this control, whether or not the product G3 is at the top of the product passage 322 of the sales unit 32 is constantly monitored (S10). This product monitoring is performed by the sales department top product detector 13. Whether the product G3 exists is determined by whether or not the product G exists at the top for a predetermined time (for example, 30 seconds). By taking a long detection time in this way, the product G that simply passes through the top of the product passage 322 and the product G that remains at the top are identified, and only the product G that remains at the top is determined as the top product G3. . Here, when the product G3 is detected, it is determined whether or not the product G1 is at the lowest position of the storage unit 31 (S11). Presence / absence of the product G1 is detected by the storage unit lowest product detector 11. If it is determined in step S11 that the product G1 exists, a product code is assigned to the product G1 and stored in the memory 103 (S12). On the other hand, when it determines with there being no goods G1 by step S11, it returns to step S10 again and monitors whether the goods G3 exist.

  During the monitoring control in step S10 and step S11, when it is determined in step S10 that the product G3 does not exist, that is, the lowest product G2 in the sales unit 32 is sold, and the entire product G in the sales unit 32 is 1 When moving downward by one, it is determined whether or not there is a product G1 at the lowest position of the storage unit 31 as in step S11 (S13). When it is determined that the product G1 exists, that is, when it is determined that the product can be replenished from the storage unit 31 to the sales unit 32, the stored product carry-out device 314 is driven (S14). Thereby, the lowest product G1 in the storage unit 31 is replenished to the highest item in the sales unit 32. When it is determined in step S13 that the product G1 does not exist, that is, when there is no supplement product in the storage unit 31, the stored product carry-out device 314 is not driven.

  As described above, in the stored product carry-out control according to the present embodiment, as long as the product G is stored in the storage unit 31, when the product is sold from the sales unit 32, the product is transferred from the storage unit 31 to the sales unit 32. G is replenished. Each time the product G is replenished from the storage unit 31 to the sales unit 32, a product code is attached to the product G1 at the lowest position of the storage unit 31.

  Next, warning deterioration determination control will be described with reference to FIG. First, it is monitored whether or not a product has been sold, and when there is a further sale of the product, it is monitored whether or not the lowest product G1 exists in the storage unit 31 (S20, S21). That is, it is monitored whether or not the product G is carried out from the sales unit 32 and whether or not there is a supplement product in the storage unit 31 when the product is carried out.

  When it is determined in step S21 that the replenishment product, that is, the product G1, exists, the timer 102 starts measuring the residence time T of the product G1 (S22). Here, since the product G1 is attached with a product code in the stored product carry-out control and the product G1 is specified by the microcomputer 10, the product G1 is transported to the sales unit 32 and further sold from the sales unit 32. The residence time T can be measured. The measurement of the residence time T varies depending on the type of the product G1, and the product G1 that measures the residence time T as it is (“residence time coefficient: N = 1”) or the product that is measured by discounting the residence time T. It is determined whether it is G1 (residence timing coefficient: N <1 ”) (S23). Thereby, the residence time T is corrected (T × N = T) (S24).

And the residence time T corrected in step S25 is:
T1 ≦ T <T2
It is determined whether or not the above condition is satisfied (S25). When it is determined that this conditional expression is satisfied, that is, when it is determined that the product G has not reached the quality degradation time T2 but has reached the quality warning time T1, the quality warning lamp 17 is turned on. (S26).

On the other hand, the residence time T of this product G is
T ≧ T2
It is determined whether or not the above condition is satisfied (S27). When it is determined that this conditional expression is satisfied, that is, when it is determined that the product G has reached the quality deterioration time T2, the quality deterioration lamp 18 is turned on (S28).

  As described above, in the warning / deterioration determination control, the residence time T is measured from when the product G is located at the lowest position of the storage unit 31, that is, when the product G1 is reached. Deterioration determination is performed.

  Subsequently, the quality control will be described with reference to FIG. In this quality countermeasure control, it is monitored whether there is a warning product G and whether there is a deteriorated product G (S30, S31). Here, the presence / absence of the warning product G and the presence / absence of the deteriorated product G are based on the information determined by the warning / deterioration determination control. If it is determined in step S30 that there is a warning product G, it is monitored whether the warning carry-out switch 14 is turned on (S32). When it is determined that the warning carry-out switch 14 is turned on, the sales product carrying-out device 324 of the sales unit 32 is driven to carry out the warning product G in the sales unit 32 to the product take-out port 5. When the lowest product G1 in the storage unit 31 is also a warning product, the stored product carry-out device 314 is driven, the product G1 is carried into the sales unit 32, and the sales product carry-out device 324 is further driven. Then, it is carried out to the product outlet 5 (S33). When the stop switch 16 is turned on while the warning product is being carried out (S34), the forced carry-out is stopped (S35). When the warning carry-out switch 14 is turned on while the forced carry-out is stopped, the carrying out of the warning product is started again. Such warning item carry-out control is continued until all the warning items are carried out.

  On the other hand, when it is determined in step S31 that there is a deteriorated product, the sale of the deteriorated product G is prohibited (S36). That is, even if the product selection button 12 is pressed, the sales product take-out device 324 is prohibited from being driven, and the deteriorated product G is not carried out. It is monitored whether or not the deteriorated carry-out switch 15 is turned on in the sale prohibited state (S37). When it is determined in this step S37 that the deteriorated carry-out switch 15 is turned on, the sale merchandise take-out device 324 of the sales unit 32 is driven. Then, the deteriorated product G in the sales unit 32 is carried out to the product takeout port 5. When the lowest product G1 in the storage unit 31 is also a deteriorated product, the stored product carry-out device 314 is driven to carry the product G1 into the sales unit 32, and the sales product carry-out device 324 is further driven. Then, it is carried out to the product outlet 5 (S38). When the stop switch 16 is turned on while the deteriorated product is being carried out (S39), the forced carry-out is stopped (S40). When the deteriorated carry-out switch 15 is turned on while the forced carry-out is stopped, the delivery of the deteriorated product is started again. Such carry-out control of the deteriorated product is continued until the carry-out of all the deteriorated products is completed.

  According to the present embodiment, quality deterioration management and quality warning management are performed not only on the product G in the sales unit 32 but also on the product G1 stored in the position closest to the sales unit 32 among the products G in the storage unit 31. Is done. The reason for this is that the storage unit 31 and the sales unit 32 are partitioned by a heat-insulating damper 33, but each time the product G is replenished from the storage unit 31 to the sales unit 32, the damper 33 is opened and sold. Warm air in the part 32 flows into the storage part 31. For this reason, at least the lowest part of the storage unit 31 is a place that is greatly affected by the heat of the sales unit 32, and the lowest product G1 is also considered to be substantially heated. Thereby, the quality of the sales commodity G can be reliably guaranteed.

  Further, in the quality degradation management of the product G, that is, when the degraded product G exists, the quality degradation lamp 18 is turned on to notify the presence of the degraded product G, the sale of the degraded product G is prohibited, The deteriorated product G can be forcibly carried out, and the quality deterioration management of the deteriorated product G is complete.

  Further, regarding the quality warning management, when the warning product G exists, the quality warning lamp 17 can be turned on to notify the presence of the warning product G, or the warning product G can be forcibly carried out. As a result, when the warning product G exists, the warning product G can be taken out and transferred to another vending machine, for example, a vending machine with good sales. it can.

  8 and 9 show a second embodiment of the vending machine according to the present invention. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The first embodiment has a quality warning lamp 17 and a quality deterioration lamp 18 and also has a warning carry-out switch 14 and a deterioration carry-out switch 15. Also, warning products and deteriorated products are carried out by the switches 14 and 15, respectively.

  In contrast, in the present embodiment, as shown in FIG. 8, a single lamp (quality warning / deterioration lamp 20) for notifying the presence of a warning product or a deteriorated product is used as one unit, and the warning product or the deteriorated product is carried out. The single carry-out switch 21 is used as a single unit.

As shown in FIG. 9, in the warning / deterioration determination control according to the present embodiment, the residence time T corrected in step S50 after the steps shown in steps S20 to S24 is corrected as in the first embodiment.
T1 ≦ T <T2
It is determined whether or not the above condition is satisfied (S50). When it is determined that this conditional expression is satisfied, that is, when it is determined that the product G has not reached the quality deterioration time T2 but has reached the quality warning time T1, the quality warning / deterioration lamp 20 is Flashes (S51).

On the other hand, the residence time T of this product G is
T ≧ T2
It is determined whether or not the above condition is satisfied (S52). When it is determined that this conditional expression is satisfied, that is, when it is determined that the product G has reached the quality deterioration time T2, the quality warning / deterioration lamp 20 is turned on (S53).

  In this way, when there is a warning product, the quality warning / deterioration lamp 20 blinks, and when there is a deterioration product, the quality warning / deterioration lamp 20 is turned on. It can be displayed.

  Further, in the quality coping control, in FIG. 7 showing the quality coping control according to the first embodiment, “warning carry-on switch ON?” In step S32 is replaced with “carry-out switch ON?”, And “ What is necessary is to replace “deterioration unloading switch ON?” With “unloading switch ON?”. As a result, two types of warning product and deteriorated product can be individually carried out with one carry-out switch 21. When the warning product and the deteriorated product are present in the plurality of product passages 312 of the various columns, the products are set to be sequentially carried out in ascending order of the column numbers assigned to the product passages 312.

  FIG. 10 shows a third embodiment of the vending machine according to the present invention. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As described in the first embodiment and the second embodiment, when there is a warning product or a deteriorated product, the presence of these products can be notified by the lamp means and can be carried out by the carry-out switch means. It is like that.

  The present embodiment can be operated in a plurality of sales modes together with the notification control and the carry-out control. Specifically, the sales mode has a normal sales mode and a deteriorated sales mode, and these sales modes can be changed to each other during operation. Here, the normal sales mode refers to a setting for carrying out a product from the storage unit 31 at every sale so that the product G in the sales unit 32 becomes a full product number. That is, the entire capacity of the sales unit 32 is used as the sales capacity. On the other hand, the deteriorated sales mode refers to a setting for carrying out the product G from the storage unit 32 so that the product G in the sales unit 32 is less than the number of full products. In the setting of this embodiment, the accommodation number is reduced by two from the full number.

  This sales mode change control will be described with reference to the flowchart of FIG. First, the vehicle is operated in the normal sales mode (S60), and when the product G reaches the quality warning time T1 during the operation of the normal sales mode (S61) or when the quality degradation time T2 is reached (S62), the sales are started. The mode is changed from the normal sales mode to the deteriorated sales mode (S63). On the other hand, when the forced carry-out operation of the warning product or the deteriorated product is ended during the operation in the deteriorated sales mode (S64), or when the quality warning time or the quality deterioration time is set to “0” (S65), the deteriorated sales mode is ended. When it is done (S66), it is changed to the normal sales mode again.

  According to the present embodiment, the product is normally sold by making the maximum use of the product storage capacity of the sales unit 32. On the other hand, when a warning product or a deteriorated product is generated during the operation, the warning product or the deteriorated product is generated. In order to suppress this increase, the storage capacity of the sales unit 32 is reduced.
