The lower portion of the cradle 19 is installed so as to be placed on the bottom wall 24b.

  The lower roller 21 includes a metallic shaft 21a and a resin roller member 21b extending outside the shaft 21a. The roller member 21b extends in the direction of the shaft 21a and is covered with a rubber member 21c. Yes. A fine groove may be formed on the surface of the rubber member 21c.

  Further, both ends of the lower roller 21 are pivotally supported on the side wall 24c and the side wall 24d of the induction heating device 17 by a shaft 21a, and one end side of the shaft 21a and the lower roller driving motor 22 are provided with a pulley 25 and are connected via a belt 23. ing.

  As described above, the induction heating device 17 fixes the bowl-shaped product support 19 having the induction heating coil 20 on the upper part of the outer frame 24 so as to lean against the back wall 24a and the bottom wall 24b. The lower roller 21 is provided in the vicinity of the lower end edge 19c, the lower part of the bottom wall 24b of the outer frame 24 is covered with the side walls 24c, 24d and the front wall 24e, and the lower roller drive motor 22 and the induction heating coil 20 generate heat inside. An exhaust heat fan 26 for forcibly exhausting heat generated by the exhaust heat fan 26 is installed, and an exhaust heat hole 27 is formed in a portion corresponding to the exhaust heat fan 26 in the front wall 24e.

  Further, the back wall 24 a is provided with a hole 28 at the top, and the hole 28 is formed in a portion corresponding to the induction heating coil 20. At least the back wall 24a is formed of an aluminum plate.

  Next, the arrangement configuration of the induction heating device 17 in the vending machine main body 11 will be described. The arrangement relationship in the height direction is as described above, and the lower end portion on which the can product 18 of the induction heating device 17 is placed is the product collection. Located below the bottom of the outlet 16, the induction heating device 17 is generally arranged using the space of the outer door 12 that normally exists below the commodity outlet 16.

  The product outlet 16 is usually not laid out at the lowermost part of the outer door 12 and is arranged at an appropriate position above the outer door 12 in order to improve the take-out property of the product buyer and reduce the burden of bending down. In addition, there is usually a space that becomes a so-called dead space below the product outlet 16.

  And the induction heating apparatus 17 arrange | positioned substantially utilizing the inside of the space used as this dead space is arrange | positioned with the inclination attitude | position so that the discharge side of the can goods 18 may face upward. Therefore, in order to discharge the can product 18 from the induction heating device 17 into the product take-out port 16, a discharge mechanism for moving the can product 18 against its own weight is necessary.

  About the induction heating apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the can product 18 is thrown into the product receiving base 19 of the induction heating device 17 from above, the lower roller 21 rotates the shaft 21a via the belt 23 hooked on the pulley 25 by the driving of the lower roller drive motor 22. The roller member 21b press-fitted into the shaft 21a is simultaneously rotated by being rotated.

  Further, as shown in FIG. 5, the lower roller drive motor 22 rotates the can product 18 by rotating the lower roller 21 counterclockwise and energizes the induction heating coil 20 with a high-frequency current to supply the can product 18. Induction heating. When the heating for a predetermined time has elapsed, the power supply to the induction heating coil 20 and the lower roller drive motor 22 are stopped.

  Since the rubber member 21c is in contact with the can product 18 when the lower roller 21 rotates, the can product 18 can rotate without rotating due to a grip and can be heated to an appropriate temperature without being heated locally. Further, the lower part of the can product 18 is sandwiched between the induction heating coil 20 and the lower roller 21, and as shown in FIG. 4, the lower roller 21 rotates counterclockwise, so that the can product 18 rotates clockwise. Since the product cradle 19 is installed as described above, the can product 18 does not jump out of the product cradle 17. Note that the lower roller 21 may be formed of a material that can be used without the rubber member 21c or without the rubber member 21c if the can product 18 can be prevented from spinning freely.

  Moreover, the product receiving stand 19 is formed longer than the can product 18 in the inverted posture. Accordingly, the lower roller 21 is also provided longer than the length of the product cradle 19, so that the can product 18 is fixed no matter where the can product 18 is placed upside down on the product cradle 17. Can be rotated without any local heating. That is, stable heating can be performed regardless of the length of the can product 18. On the other hand, the upper part of the product cradle 19 is open and does not have a member for regulating the can product 18 and can be heated uniformly on the lower contact surface with the product cradle 19 by rotation. It can be heated without being influenced by. That is, stable heating quality can be provided regardless of the size of the can product 18.

  The lower roller 21 as the rotating means preferably has an axial length longer than the length of the product receiving base 19, but a substantial contact surface with the can product 18 even if the length is shorter than this. However, there is no problem as long as it can be sufficiently secured in the axial direction of the lower roller 21 and can stably rotate.

  Although not limited, if the length of the contact surface of the lower roller 21 is longer than the total length of the can product 18 that is assumed to be accepted as a guide, the length of the product cradle 19 relative to the total length of the can product 18 is assumed. From the reasonable range of dimensional design in the direction, even if the can product 18 is received in the product cradle 19 even if the can product 18 is displaced in the axial direction, a substantial portion of the can product 18 in the full length direction is substantially contacted with the lower roller 21. Therefore, there will be no major hindrance to stable rotation.

  Further, if a fine groove is formed in the rubber member 21c, the idle rotation of the can product can be further reduced and driven to rotate.

  Further, when the can product 18 is heated, the induction heating coil 20 generates heat and heat is also transferred to the back wall 24a. Since the back wall 24a is an aluminum plate, the heat conductivity is lower than that of the iron plate and heat transfer can be reduced. However, since the back wall 24a is not sufficient, the exhaust heat fan 26 causes the external air from the hole 28 in the back wall 24a. Can be communicated with the bottom hole 29 formed in the bottom wall 24b to exhaust heat from the heat exhaust hole 27 to the outside, thereby preventing abnormal heating of the back wall 24a. Further, since the heat generated by the lower roller drive motor 22 can be reduced by the exhaust heat fan 26, the reliability of the motor can be ensured.

  On the other hand, as shown in FIG. 4, the attitude control member 30 may be formed on the upper part of the product cradle 19 of the induction heating device 17 so as to be movable in the width direction (length direction) of the product cradle 19. The attitude control member 30 is movably inserted into an upper roller 31 formed on the upper part of the commodity receiving base 19. The upper roller 31 is formed of a metallic shaft 31a as a shaft and a resin roller member 31b extending in the width direction outside the shaft 31a. A groove 31c is formed in the roller member 31b in the direction of the shaft 31a.

  The upper roller 31 is formed on the back wall 24a side of the upper part of the product cradle 19 so as to extend in the width direction of the product cradle 19, and the attitude control member 30 is made of resin and is not damaged even when it comes into contact with the can product. In this way, it extends horizontally toward the front wall 24e.

  The upper roller 31 is rotationally driven by an upper roller drive motor 32. The upper roller drive motor 32 is arranged side by side with the lower roller drive motor 22 provided below the product cradle 19. The upper roller 31 and the upper roller drive motor 32 are connected via a belt 33.

  About the attitude | position control mechanism of the induction heating apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  A can product 18 is introduced from above the induction heating device 17. At this time, the can product 18 may be set in the inverted position, but the can product 18 may be placed in the product position 19 in a standing position. If it heats as it is, only a contact part with the goods receiving stand 19 will raise | generate local heating, and there exists a possibility that goods may be damaged or it may not be heated to appropriate temperature.

  Therefore, first, the attitude control member 30 is positioned at the end of the product cradle 19 that is the initial position. When the can product 18 is put into the induction heating device 17, the upper roller drive motor is used regardless of the attitude state of the can product 18. 32, the upper roller 31 is rotationally driven, and the attitude control member 30 moves along the groove 31c from the end of the commodity receiving base 19 to the other end. And if it moves to an edge part, the upper roller drive motor 32 will reversely rotate, the upper roller 31 will be reversely rotated, and the attitude | position control member 30 will be returned to an initial position. And after confirming having returned to the initial position, heating operation is performed.

  Accordingly, if the can product 18 is in a standing posture on the product receiving stand 19, the can product 18 can be brought down on the product receiving stand 19 by the movement operation of the posture control member 30, thereby preventing local heating due to the standing posture. it can. Since the posture control member 30 is disposed so as to hit the upper part of the middle of the can product 18 when the can product 18 is in the standing posture, it is possible to prevent the product from being dragged on the product stand 19 while standing. it can.

  Further, since the attitude control member 30 reciprocates the product cradle 19 in the width direction, if it is determined that the can product 19 does not fall and the attitude control member 30 does not return to the initial position, the heating operation is not performed, so Local heating and damage can be prevented.

  In addition to the above, the posture control member 30 may be controlled by one-sided movement without reciprocating to determine the next heating operation. In this case, the time from when the can product 18 is charged until the heating operation is performed can be shortened, and the waiting time for the user can be reduced.

  Next, the carry-out mechanism of can goods by the induction heating device 17 will be described.

  The direct operation of the carry-out mechanism is to slide the can product 18 after being heated at the product receiving stand 19 by the carry-out member 33 in the longitudinal direction of the can and push it out. The carry-out member 33 is formed of a resin material so as not to be damaged even when it comes into contact with the can product 18. The carry-out member 33 has an insertion hole 33 a having a groove at the end thereof, and the lower roller 21 is inserted into the carry-out member 33. ing. The lower roller 21 also has a groove 34 extending in the axial direction, and a series of contact portions 35 that contact the can product 18 between the grooves 34 extend in the axial direction. The surface of the contact portion 35 is covered with a rubber member 36.

  At one end portion of the lower roller 21 connected to the lower roller drive motor 22 via a belt 33, a standby portion 37 is formed to wait for the carry-out member 33 in which the groove 34 and the rubber member 36 are not formed. The standby portion 37 is formed integrally with the roller member 21b constituting the lower roller 21, and the outer diameter of the standby portion 37 is smaller than the outer diameter of the roller member 21b. A spring member 38 is inserted into the standby portion 37 and fixed to the end of the roller member 21b.

  Further, an opening 39 is formed at the end of the product receiving base 19 of the induction heating device 17, and an opening / closing member 40 that is movable in the vertical direction for opening and closing the opening 39 is formed. FIG. 8 is a view taken in the direction of arrow C in FIG. The opening / closing member 40 is movable in the vertical direction along rails 41 formed in the vertical direction on the back wall 24a and the front wall 24e.

  The opening / closing member 40 is made of resin, and has an opening 40a that is open in the vertical direction at a substantially central portion, and teeth 40b are formed in the opening 40a so as to move in the rack and pinion manner with the opening / closing member drive motor 42. .

  The opening / closing member drive motor 42 is disposed in the same space as the upper roller drive motor 32 and the lower roller drive motor 22.

  About the carrying-out mechanism of the induction heating apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The can product 18 is introduced from above the induction heating device 17, the heating operation is performed after the operation of the attitude control mechanism of the can product 18, and after heating to an appropriate temperature, the can product 18 is carried out from the product receiving stand 19 to the outside. The operation by the carry-out mechanism is performed.

  During the heating operation, the lower roller 21 rotates, so that the abutting portion 35 contacts the can product 18 to rotate (spin) the can product 18 and energize the induction heating coil 20 to induct the can product 18. Heat. As a result, the series of abutting portions 35 abut against the can product 18, and the can product 18 can be rotated.

  At this time, the carry-out member 33 is configured to move to the standby portion 37 side which is the initial position according to the relationship with the groove 34 formed in the insertion hole 33 by the rotation of the lower roller 21, and the carry-out member 33. Is separated from the groove 34 and the contact portion 35 and guided to the standby portion 37. The carry-out member 33 is maintained while slipping (idling) in the standby portion 37. As the lower roller 21 rotates, the carry-out member 33 that is to move further toward the side wall 24c is urged toward the product receiving base 19 by the spring member 38, so that the load applied to the side wall 24c can be reduced. Further, by providing the spring member 38, the carry-out member 33 can be prevented from being damaged.

  When the heating operation is finished and the lower roller 21 is stopped, the can product 18 is then carried out. At this time, the lower roller drive motor 22 is reversely energized, and the lower roller 21 performs reverse rotation during heating. As a result, the carry-out member 33 moves along the groove 34 from the standby portion 37 of the lower roller 21 and comes into contact with the can product 18 in the inverted position and slides by pushing on the product stand 19 in the inverted position, and is carried out to the outside. To do.

  When the carry-out member 33 moves to the end of the product receiving stand 19, the lower roller 21 is rotated in the same direction as that during heating, and the carry-out member 33 is moved to the standby position 37 that is the initial position.

  Therefore, since the heated can product 18 can be automatically carried out to the outside, the user does not need to put his hand in the induction heating device 17 and take out it, thereby ensuring safety. Further, after the product is carried out, it is possible to control whether or not the product is jammed in the unit by returning the carry-out member 33 to the standby position 37. If the product does not return to the standby position 37 for a predetermined time, it is abnormal as a product jam. Judgment can be made.

  Next, at the time of standby before the can product 18 is put into the induction heating device 17, the opening / closing member 40 closes the opening 40a so that the product receiving base 19 is not touched, so that foreign matter or the like does not enter. I have to. Moreover, in addition to preventing a part of the can product from accidentally jumping out of the induction heating device 17 when the can product 18 is charged, it also has a role of increasing the heating efficiency without opening the space inside the device during heating.

  When the can product 18 is thrown in, the posture control mechanism maintains the inverted posture, heats the product by the heating operation, and then drives the lower roller 21 to start moving the carry-out member 33 from the initial position, while simultaneously opening and closing the member. The drive motor 42 is driven to open the opening / closing member 40 along the rail 41, and the can product 18 heated to an appropriate temperature is carried out. The opening / closing member 40 is moved downward by a rack and pinion type with teeth 40b formed in the vertical direction by driving of the opening / closing member drive motor 42, opens the opening 39, and carries the product out of the product receiving stand 19.

  At this time, the carrying-out member 33 is moved to the opening 39, and the opening 39 is closed by the carrying-out member 33. When the can product 18 is carried out, a hand or a foreign object is inserted into the inside from the opening 39. Can be prevented.

  Before the unloading member 33 moves toward the initial position, the opening / closing member drive motor 42 is driven first, the opening 39 is closed by the opening / closing member 40, and then the unloading member 33 is returned to the initial position. In particular, it is possible to prevent a hand or a foreign object from entering the product receiving stand 19. Moreover, safety can be ensured.

  Further, since the drive motor is disposed in the same space and the exhaust heat fan 26 is provided for exhaust heat, it is possible to prevent a decrease in the reliability of the motor due to heat generated by the drive motor.

  And the discharge | emission mechanism which discharges can goods 18 out of the induction heating apparatus 17 by the arrangement | positioning relationship of the height direction of the induction heating apparatus 17 and the goods extraction port 16 mentioned above is the induction heating apparatus inclinedly installed toward diagonally upward. 17 is configured to slide and move obliquely upward in the longitudinal direction of the product 18 on the surface of the product receiving stand 19 provided on the product 17. That is, the carry-out member 33 of the carry-out mechanism moves while pushing up the can product 18 obliquely upward, and finally the can product 18 can be dropped and discharged from the opening 39 into the product take-out port 16.

  Therefore, by taking such a configuration, even if the induction heating device 17 is disposed so as to be relatively downward with respect to the product outlet 16, the can product 18 can be discharged without any trouble. In an ordinary vending machine, the induction heating device 17 can be provided by effectively utilizing the space below the product outlet 16 that is a dead space. For this reason, it is not necessary to provide the induction heating device 17 by dividing the effective internal space used for the product storage room 11a as in the prior art, and the internal space can be used to the maximum extent for the product storage room 11a.

  Furthermore, since the induction heating device 17 is housed in the space below the product outlet 16 on the outer door 12 side, the internal structure including the product storage chamber 11a of a vending machine generally used at present, There is an advantage that it is possible to realize a high-value-added vending machine having a new function of rapidly heating a product with the induction heating device 17 without changing the configuration of the outer door 12 including the product outlet 16 almost.

  In the present embodiment, the induction heating coil 20 and the lower roller 21 that is the rotating means have been described on the assumption that they are arranged at positions separated by a predetermined distance L. Since both the mechanism and the carry-out mechanism have a function and effect peculiar to the mechanism itself, the arrangement relationship between the induction heating coil 20 and the lower roller 21 that is the rotating means is not a predetermined separation relationship. Of course, a combination configuration is possible even when the region of the induction heating coil 20 and the position where the lower roller 21 serving as the rotating means overlaps, and a specific effect can be expected.

  Next, the non-contact type temperature detection means 43 which is a temperature detection means for detecting the temperature of the can product 18 will be described.

  As shown in FIG. 4, a holder 44 for installing the non-contact temperature detecting means 43 is fixed to the front wall 24e with screws or the like. A non-contact temperature detecting means 43 (for example, an infrared sensor) is held in the holder 44.

  The non-contact type temperature detecting means 43 is disposed in the vicinity of the lower roller 21 at a substantially intermediate portion in the longitudinal direction (width direction) of the commodity receiving base 19. Since the can product is disposed in contact with the lower roller 21, the distance between the can product and the non-contact temperature detecting means 43 can be kept almost constant regardless of the outer diameter of the can. Accordingly, the can product 18 can be arranged at a certain distance from the can product 18 regardless of where the can product 18 is inverted.

  About the detection means of the can goods 18 of the induction heating apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The can product 18 maintained in the inverted position on the product cradle 19 rotates by the rotation of the lower roller 21. When the can product 18 detects that the surface thereof has reached a predetermined temperature by the non-contact temperature detecting means 43, the power supply to the induction heating coil 20 is stopped, and the rotational drive is also stopped. Therefore, by installing the non-contact type temperature detecting means 43 in the vicinity of the lower roller 21 and in a substantially intermediate portion in the longitudinal direction of the product receiving base 19, it is possible to heat the can product to an appropriate temperature regardless of the outer diameter of the can product.

It is formed so that it can be taken out.

  As shown in FIG. 11, the induction heating apparatus 100 is operated in the induction heating apparatus 100 while maintaining the longitudinal acceptance state of the can product in an oblique arrangement, with the product outlet 16 side being higher than the other side. The

  In the product sample display room 13, a product sample display unit 13 a dedicated for cooling is displayed in the upper part, and a product sample display unit 13 b that can be heated by the induction heating device 100 is formed in the upper and lower sections by a partition plate 800 and displayed. The product sample display unit 13a has the same sample configuration as that of the prior art, and one product selection button 801 is configured corresponding to one product sample.

  In the product sample display section 13b, a display section 803 is displayed on the partition plate 800 to indicate that the product of the displayed product sample 802 is heated by an induction heating method, so that it takes more time than usual. .

  Under the product sample 802, two product selection buttons 804a and 804b corresponding to one product sample 802 are configured. Specifically, the product selection button 804a is displayed with “hot” when the sales temperature setting is about 55 ° C., and the product selection button 804b is displayed with “slim” when the sales temperature setting is about 50 ° C. It is configured.

  The product sample 802 of the product sample display unit 13b is a product sample 802 configured in a flat card shape unlike the product sample of the product sample display unit 13a, and the product of the product sample display unit 13b is displayed to the user. However, unlike the products in the product sample display section 13a, it is configured to appeal that the heating is based on the induction heating method.

  The induction heating device 100 is provided with non-contact temperature detecting means 110 described later, and the non-contact temperature detecting means 110 detects the surface temperature of the can product 18 to estimate the content beverage temperature, and the estimated contents When the can surface temperature at the time when the beverage temperature reaches the sales set temperature becomes the specified temperature, a signal from the non-contact type temperature detection means 110 is input to the product induction heating control unit 502 described later, and induction heating is performed. The energization to the coil 102 is stopped.

  Next, the heating structure by the induction heating apparatus 100 will be described.

  The induction heating apparatus 100 includes a product cradle 101 having a substantially chamfered cross-sectional shape that receives and holds the can product 18 in an inverted position, an induction heating coil 102 wound around the back surface of the product cradle 101, and a product cradle 101. There are a lower roller 103 as a rotating means that contacts the peripheral surface of the can product 18 from below, and a lower roller drive motor 111 is installed below the lower roller 103. The lower roller 103 and the lower roller drive motor are belts (not shown) And the lower roller 103 is driven to rotate.

  The induction heating coil 102 and the lower roller 103 are arranged at a predetermined distance L as in the first embodiment, and the lower roller 103 is embedded in the area where the induction heating coil 102 is arranged. It is not what has been.

  In addition, the shape of the product cradle 101 and the induction heating coil 102 is not limited to a substantially chamfered cross-sectional shape or a bowl shape as described above, but may be a shape that can receive and hold the can product 18 in an inverted position and perform appropriate heating. That's fine.

  The product receiving base 101 is formed of a nonmagnetic material such as resin, and a tempered glass plate 500 having a substantially rectangular shape is fitted into a portion where the can product 18 comes into contact and rotates as shown in FIG. Since the can product 18 slides in contact with the product cradle 101, it is desirable that the can product 18 be formed of ceramic or glass excellent in scraping or wear on the surface of the product cradle 101. In particular, since the product falls from the upper product storage chamber 11a to the product receiving base 101, it is desirable to use the tempered glass plate 500.

  Further, the product receiving base 101 is formed of the resin-made coil case 101a as described above, and the portion that comes into contact with the can product forms a substantially rectangular groove 115 in the coil case 101a, and the tempered glass plate is formed in the groove 115. 500 is inserted, the induction heating coil 102 is fixed behind the coil case 101a, and a plurality of substantially rectangular magnetic ferrites 104 are fixedly arranged in the coil case main body 101b serving as the back cover of the coil case 101a. Thus, a product receiving base 101 is configured. A coil thermistor 105 that detects the temperature of the induction heating coil 102 is disposed in the coil case main body 101b.

  Further, by sticking the heat conductive sheet 116 to the back surface of the coil case 101a, the heat conductivity of the induction heating coil 102 can be increased, the coil heating temperature of the induction heating coil 102 can be reduced, and the heating efficiency of the can product can be increased. In addition, a decrease in reliability due to heat generation of the induction heating coil 102 can be prevented.

  Moreover, since the thermal conductive sheet 116 absorbs the drop impact when the can product is conveyed from the upper carry-out portion to the product receiving table 101, damage to the product receiving table 101 can be reduced.

  The induction heating device 100 is formed so as to cover the periphery with an outer frame 106, and the product heating unit 100 a as described above is accommodated in the upper portion of the induction heating device 100, and the lower roller driving motor 111 that drives the lower roller 103 is accommodated in the lower portion. The drive unit 100b is formed.

  Further, the lower roller 103 is supported at both ends by a receiving portion 107 constituted by an outer frame 106. The lower roller 103 includes a metal shaft portion 103a on one end side and a resin roller member 103b extending inside the shaft portion 103a. The roller member 103b serves as a shaft on the other end side. , Supported by the receiving portion 107. Therefore, both end portions of the roller member 103b do not have the same shape, and only the roller member 103b is configured to be detachable with the shaft portion 103a remaining in the outer frame 106.

  The roller member 103b is composed of a resin core member 108 and a rubber member 103c that directly contacts the product and applies a rotational force to the product itself, and the rubber member 103c spirals between the threaded portions 108c formed on the core member 108. Configured.

  The rubber member 103c extends in the direction of the shaft portion 103a of the roller member 103b and is integrally formed in a spiral shape on the outer peripheral surface of the core member 108. The core member 108 has a plurality of holes 103d from the surface toward the center. Another connecting hole 103e is formed so as to extend in the axial direction so that adjacent holes 103d communicate with each other in the vicinity of the center of the core member 108, and a plurality of holes 103d are formed inside the core member 108. The portion 103e communicates in the axial direction.

  The rubber member 103c is formed in two colors in the axial direction of the core member 108, so that the rubber member 103c is filled in the hole 103d and the connecting hole 103e. Therefore, the roller member 103b is driven to rotate from the surface of the core member 108. It is possible to reduce the occurrence of displacement or peeling of the rubber member 103c, and the can product 18 can be rotated normally.

  Also, if the rubber member 103c is damaged due to wear or deterioration due to sliding with the can product, the roller member 103b is removed from one receiving portion 107, and the roller member 103b is pulled out from the shaft portion 103a formed on the other side. Can be replaced with a new roller member 103b.

  Further, in FIG. 16, the portion of the core member 108 in which the rubber member 103c is formed in a spiral shape is formed as a groove 108b that is one step lower than the protrusion 108a of the core member 108, and the rubber member is formed in the groove 108b. 103c is formed. Accordingly, a part of the side portion of the rubber member 103c spirally formed in the axial direction of the core member 108 is covered with the protrusion 108a.

  Further, an upper roller 201 is configured in the longitudinal direction above the product receiving base 101, and the upper roller 201 is configured to control the can product 18 carried out from the product storage unit to the product receiving base 101 so as to be in an inverted posture. The control member 200 is configured to be movable in the longitudinal direction on the product receiving base 101.

  Next, the arrangement configuration of the induction heating device 100 in the vending machine main body 11 will be described. The arrangement relationship in the height direction is as described above, and the lower end portion on which the can product 18 of the induction heating device 100 is placed is the product collection. Located below the bottom of the outlet 16, the induction heating device 100 can be arranged by utilizing the space of the outer door 12 that normally exists below the commodity outlet 16.

  The product outlet 16 is usually not laid out at the lowermost part of the outer door 12 and is arranged at an appropriate position above the outer door 12 in order to improve the take-out property of the product buyer and reduce the burden of bending down. In addition, there is usually a space that becomes a so-called dead space below the product outlet 16.

  And the induction heating apparatus 100 arrange | positioned substantially utilizing the inside of the space used as this dead space is arrange | positioned with the inclination attitude | position so that the discharge side of the can goods 18 may face upward. Therefore, in order to discharge the can product 18 from the induction heating device 100 into the product take-out port 16, a discharge mechanism for moving the can product 18 against its own weight is necessary.

  In addition, the product induction heating control unit 502 is arranged below the product take-out port 16 by utilizing the space that becomes a so-called dead space, and is arranged in the vicinity of the induction heating device 100, so that the distance between the high voltage units is shortened. It can be configured and safety can be improved.

  About the induction heating apparatus 100 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the user presses the product selection button 804a and designates “hot” as a hot product, the main control unit 501 that controls the entire vending machine preheats to about 35 ° C. so that the product does not deteriorate in the vending machine body 11. The can product 18 thus taken out is transported to the induction heating device 100. Then, the set temperature information of 55 ° C. of the selected “collection” is input from the main control unit 501 to the product induction heating control unit 502, and the induction heating device 100 is energized to operate the attitude control member 200, The lower roller that checks whether the acceptance state of the product 18 is the inverted posture, detects that the posture control member 200 has returned to the initial position, energizes the induction heating coil 102, and rotates the can product 18 in rotation. 103 is rotated to start the heating operation. Then, the temperature of the can product 18 is detected by a non-contact temperature detecting means 110 described later, and when the set temperature is reached, the energization to the induction heating coil 102 is stopped and the heating operation is stopped.

  Therefore, since the user can set the can product 18 at a desired temperature only by operating the product selection button 804a, the time from the operation of the product selection button 804a to the heating operation can be shortened. Can be prevented from waiting unnecessarily, and user operability can be simplified. In addition, since the energization of the induction heating coil 102 is started after it is confirmed that the attitude control member 200 returns to the initial position and the can product 18 is held in a normal state, it is stable with respect to the can product 18. Heating can be performed.

  If it is not possible to detect that the posture control member 200 has returned to the initial position, the induction heating coil 102 is not energized, assuming that the product is not accepted in the inverted posture or that the product is clogged in the carry-out passage. Stop the heating operation. Then, the product selection button of the product sample display section 13a is turned on to switch to sales of another product. At this time, it is possible to promote the sales to the user by performing a sold-out display or the like so that the product corresponding to the product sample display section 13b cannot be selected. In this case, the price may be returned by operating the return lever.

  In addition, although the product sample display room 13a is a product dedicated to cooling, there may be a product group that can be heated by a heater or the like as usual, and when the product cannot be heated by the induction heating method, the product sample display unit 13a side A product by heating the heater can be selected.

  Further, since the rubber member 103c is in contact with the can product 18 during rotation of the lower roller 103, the can product 18 can be rotated on the product receiving base 101 without idling, and can be heated at an appropriate temperature without being overheated locally. Further, the rubber member 103c is filled in the hole 103d and the connecting hole 103e formed in the core member 108 constituting the roller member 103b, and is formed in a spiral shape. The rubber member 103c can be prevented from being displaced or peeled off from the lower roller 103 due to rubbing, and the strength can be increased, the idle rotation of the can product can be reduced, and local overheating can be prevented.

  When replacing the lower roller 103 due to the above-mentioned displacement or peeling, deformation or breakage due to product drop impact, aging deterioration, etc., by removing the receiving portion 107, one side of the lower roller 103 is detached, and the lower roller 103 By pulling out the roller member 103b in the axial direction, the roller member 103b can be removed with the shaft portion 103a remaining in the receiving portion 107 on the other side. Then, by inserting a new roller member 103b into the shaft portion 103a, replacement can be easily performed, workability can be improved, and reliability of heating quality of can products can be improved.

  Further, in order to reduce or suppress the wear of the product cradle 101 due to the rotation of the can product 18, a tempered glass plate 500 is fitted in a portion that is molded from resin and becomes a portion that comes into contact with the product of the product cradle 101. In the embodiment, a substantially rectangular tempered glass plate 500 is fitted into the product abutting surface of the coil case 101a serving as the product receiving base 101.

  Similarly to the first embodiment, the product receiving base 101 and the lower roller 103 are disposed at a predetermined distance L, and the lower roller 103 is embedded in the region where the induction heating coil 102 is disposed. It does not exist.

  A plurality of substantially rectangular first ferrites 104 arranged in a coil case main body 101b serving as a back cover of the coil case 101a constituting the product cradle 101 are arranged in three upper and lower stages at intervals on the left and right sides. It is arranged. Then, the induction heating coil 102 wound in an elliptical shape a plurality of times in a substantially concentric manner is arranged on the upper portion of the first ferrite 104, and the central space portion 102a serving as a substantially central portion of the induction heating coil 102 is arranged on both the left and right sides. The second ferrite 114 having a rectangular shape extends from the central space portion 102a of the induction heating coil 102 to the central space portion 104a of the first ferrite 104. By inserting and arranging the first ferrite 104 in a substantially vertical direction, the generated magnetic flux can be released to the product side, and the efficiency of the temperature rise of the can can be increased. Further, the magnetic flux also concentrates on the ferrite 104 on the can side, so that the input efficiency to the product is improved and the heating efficiency of the product can be improved.

  The induction heating coil 102 is configured to have a substantially chamfered cross section along the shape of the product cradle 101, and a flat portion 102b corresponding to a flat portion (tempered glass plate 500) where the can product contacts the product cradle 101; It is comprised by the bending part 102c. The bent portions 102c at both the upper and lower ends are configured to extend in a substantially vertical direction and a substantially horizontal direction, respectively, and the product receiving base 101 is also configured correspondingly. It is easy to receive, and even if the can product hits the portion of the product receiving table 101 corresponding to the bent portion 102c, it can be received and held in the product receiving table 101, so that it is possible to prevent the heating operation without the can product.

  If the 2nd ferrite 114 is made to project toward the coil case 101a surface rather than the induction heating coil 102, the magnetic flux can be further released to the can side, and the heating efficiency of the can product can be further increased.

  Next, the carry-out mechanism of the can product by the induction heating device 100 will be described.

  The operation of the carry-out mechanism is performed by the carry-out member 300, and the can product 18 after being heated by the product receiving base 101 is slid in the longitudinal direction of the can (longitudinal direction of the product receiving base 101) and pushed out. is there. That is, the carry-out member 300 is configured to be movable in the axial direction of the lower roller 103 by the rotational drive of the lower roller 103 described above.

  In FIG. 14, the outer frame 106 includes pusher means 301 that pushes the unloading member 300 in the standby position so as to be interlocked with the rotational drive of the lower roller 103. The pusher unit 301 is located on the side of the upper roller 201 and the lower roller 103 in the longitudinal direction. The pusher unit 301 has one end engaged with the attitude control member 200 and the other end engaged with the unloading member 300. An elastic member 302 is provided on the side. The pusher means 301 is formed of a plate-like member, and a rotation shaft portion 300a is formed at a substantially central portion. The pusher means 301 is centered on the rotation shaft portion 300a by the contact of the attitude control member 200 or the carry-out member 300. Is configured to be rotatable.

  The induction heating apparatus 100 is inclined so that the product discharge side of the product receiving base 101 is upward, and the pusher means 301 is configured on the lower side of the product receiving base 101. Further, since the upper roller 201 and the lower roller 103 are configured in parallel with the inclined arrangement of the product receiving base 101, the lower end side where the elastic member 302 of the pusher means 301 is arranged when receiving no external force. Is maintained in a direction away from the lower roller 103.

  Alternatively, the pusher unit 301 may be configured such that the center of gravity is on the upper-side posture control member 200 side by the rotating shaft portion 300a, and the elastic member 302 is maintained in a direction away from the lower roller 103.

  About the carrying-out mechanism comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the can product 18 is conveyed from the product storage unit to the induction heating device 100 and dropped onto the product receiving table 101, first, the posture control member 200 is driven in a direction to push the can product 18 from the standby position to the outside by the rotational drive of the upper roller 201. The product is reciprocated in the longitudinal direction of the product receiving base 101 so as to move to a predetermined position and return to the standby position. Thus, the can product 18 is maintained in the inverted posture. Simultaneously with the rotation of the upper roller 201, if the lower roller 103 moves the carry-out member 300 and pushes the can product 18 outward, the lower roller 103 is driven to rotate backward for a predetermined time. The lower part of the product 18 is made unstable.

  Accordingly, when the can product 18 is maintained on the product receiving base 101 in a standing posture, the posture control member 200 by the rotational drive of the upper roller 201 is brought into contact with the upper portion of the can product 18 and the lower roller 103 is driven by the reverse rotation. By making the lower portion of the can product 18 unstable, the can product 18 can be laid down regardless of the size of the can product 18, and the next heating operation can be performed.

  During the heating operation, the lower roller 103 rotates forward to rotate the can product 18. At this time, the rubber member 103c comes into contact with the can product and rotates the can product. At this time, the induction heating coil 102 is energized with a high-frequency current to inductively heat the can product 18.

  Further, while the lower roller 103 is rotating, the carry-out member 300 stands by while slipping (idling) at a portion where the threaded portion 108c of the lower roller 103 is not configured, and is kept from moving. At this time, the elastic member 302 of the pusher means 301 is held at a separated position so as not to contact the carry-out member 300. During heating, the upper roller 201 stops rotating, and the attitude control member 200 is maintained in a stopped state at the standby position. The standby position of the attitude control member 200 is stopped at a position where it does not come into contact with the engaging portion on one end side of the pusher means 301.

  When the heating operation is finished and the lower roller 103 is stopped, the can product is then carried out. At this time, the lower roller 103 reversely energized to the lower roller drive motor 111 is rotated in the reverse direction. Further, the upper roller 201 is driven to rotate, and the upper roller 201 is rotated until the attitude control member 200 presses one end of the pusher unit 301. As a result, the pusher means 301 rotates around the rotation shaft portion 300a, the elastic member 302 configured on the other end side contacts the carry-out member 300, and pushes the carry-out member 300 in the axial direction of the lower roller 103 by the elastic force. put out.

  As a result, the carry-out member 300 releases the slip state, engages with the threaded portion 108c, and can carry out the can product to the outside by the rotation of the lower roller 103.

  Accordingly, since the carry-out member 300 does not receive a slight external force from the elastic member 302 during heating, no abnormal noise such as a rattling sound due to contact with the end surface of the threaded portion 108c is generated, and the lower roller 103 is smoothly moved. Can be rotated.

  When the carry-out member 300 moves to the end of the product receiving base 101, the lower roller 103 is rotated in the same direction as that during heating to move the carry-out member 300 to the standby position that is the initial position.

  An opening 504 communicating with the product outlet 16 is formed at the end of the product receiving base 101 of the induction heating device 100, and an openable / closable member 505 that opens and closes the opening 504 is formed. The opening / closing member 505 is operated and moved downward almost simultaneously with the movement of the member 300, the product outlet 16 and the product receiving base 101 are communicated, and the can product 18 is discharged to the product outlet 16 by the extrusion of the carry-out member 300. The Thereafter, the carry-out member 300 returns to the standby position, and the opening / closing member 505 moves upward to block between the commodity receiving base 101 and the commodity outlet 16.

  As a result, the can product can be automatically carried out to the outside, so that the user does not need to put the hand into the induction heating device 100 and take out the product, thereby ensuring safety. Further, by returning the carry-out member 300 to the standby position, it is possible to control whether the product is jammed in the induction heating device 100.

  In addition, the opening / closing member 505 is in a state where the induction heating device 100 and the product outlet 16 are shut off during standby, so that it is possible to prevent mischief and to prevent dust and insects from entering the induction heating device 100. In addition, by providing a connecting plate 506 that is provided outside the opening / closing member 505 and connects the product receiving base 101 and the product outlet 16, the gap between the product receiving base 101 and the product outlet 16 can be filled and connected. When the member 505 is opened, the external force applied to the can product 18 pushed out by the carry-out member 300 can be reduced, and the product can be smoothly discharged into the product take-out port 16.

  In particular, even when the induction heating apparatus 100 is not driven, when the carry-out member 300 is periodically reciprocated by a predetermined section and the carry-out member 300 does not move to the end of the product receiving base 101 or does not return to the standby position. The safety of the induction heating device 100 is ensured by judging that there is a foreign substance inside and setting the product selection button of the product to be heated by the induction heating device 100 to a sold-out state so that it cannot be sold. can do.

  Next, a cooling air path configuration for cooling the induction heating coil 102 will be described.

  As shown in FIG. 17, a drive unit 100b that houses a drive motor and the like is formed below the product heating unit 100a.

  A blower fan 400 is housed in the drive unit 100b, and a duct 401 that blows air from the blower fan 400 toward the product heating unit 100a is configured. The blower fan 400 is a centrifugal blower in which air flows in a centrifugal direction at a right angle to an axis called a multiblade fan or a turbofan, and the duct 401 is an outlet of the sending fan 400 and an opening 402 of the product heating unit 100a. Are connected.

  The opening 402 is configured as an air passage so as to communicate with the resin-made coil case 101a constituting the product receiving base 101. Specifically, air flows between the induction heating coil 102 and the first ferrite 104. Thus, a space 403 is formed to constitute an air passage. That is, an air passage is formed to flow air from the lower side to the upper side of the induction heating coil.

  The positional relationship between the blower fan 400 in the drive unit 100b, the lower roller drive motor 111, and the upper roller drive motor 112 is such that the lower roller drive motor 111 and the upper roller drive motor 112 are disposed in the vicinity of the suction port 400a of the blower fan 400. Has been.

  About the cooling air path comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  By operating the blower fan 400, the air in the drive unit 100b is sucked, the air is forced into the coil case 101a through the duct 401, and the air is guided between the induction heating coil 102 and the first ferrite 104, In particular, the induction heating coil 102 is cooled, and as a result, the surface of the product cradle 101 can be cooled, and by providing an air path between the induction heating coil 102 and the first ferrite 104, the induction heating coil 102 Since the gap with the product cradle 101 can be close, the coil temperature rise can be reduced and the heating efficiency of the can product 18 can be increased.

  Further, the coating covering the surface of the induction heating coil 102 can be kept at an insulation temperature (about 160 ° C.) or lower, the induction heating coil 102 can be cooled, and the surface temperature of the product receiving base 101 can be lowered. The destruction of the induction heating coil 102 is suppressed, and the hot product can be continuously heated by the induction heating device 100, so that continuous sales are possible. Therefore, it contributes to sales promotion.

  The blower fan 400 is controlled by continuous operation at least during heating, but even when the induction heating device 100 is not operated, the heating operation by the induction heating device 100 is suddenly performed by always operating continuously. Even in this case, the safety of the induction heating coil 102 can always be maintained.

  The air is exhausted to the outside from the exhaust hole 113 formed in the outer frame 106 on the upper back surface of the coil case 101a, so that the heat exchange efficiency can be increased and the heating efficiency of the induction heating coil 102 can be increased.

  Further, a base portion 600 for fixing the induction heating device 100 is formed on the back surface of the outer door 12, and the outer frame 106 is fixed to the base portion 600 with screws or the like. For this reason, a space portion 601 can be secured between the outer door 12 and the induction heating device 100 by the depth height of the base portion 600. The base portion 600 has a plurality of communication holes 600a formed in the vertical direction.

  Thus, the air discharged from the exhaust hole 113 passes through the space portion 601 formed between the outer door 12 and the induction heating device 100, and further passes through the communication hole 600 a formed in the base portion 600. Since the heat generated from the induction heating coil 102 can be efficiently exhausted, particularly the heating operation by the induction heating device 100 is performed almost continuously. In this case, it is possible to suppress the product heating operation while the product receiving base 101 is in a high temperature state, and to prevent the temperature of the induction heating coil 102 and the product receiving base 101 from further rising.

  As a result, the induction heating coil 102 exceeds the insulation coating temperature, and the safety device operates, so that it is possible to prevent the safety and the deterioration of the heating quality such as stopping the heating halfway. Can achieve continuous sales of products.

  Safety can be ensured, and continuous sales of hot products by continuous operation of the induction heating apparatus 100 are possible.

  Further, the blower fan 400 can efficiently eliminate heat generated by the lower roller driving motor 111 and the upper roller driving motor 112, and can prevent the inside of the driving unit 100b from becoming high temperature. Reliability can be ensured.

  Moreover, although the air path structure by the ventilation fan 400 was comprised only in the coil case 101a, you may provide an air path so that a part of air may be ventilated to the upper surface of the coil case 101a, ie, the goods stand 101 surface. As a result, the temperature of the surface of the product cradle 101 can be lowered, and dust, dust, and the like can be prevented from adhering to the surface of the product cradle 101. As a specific air path configuration, the duct 401 may be branched in the middle so that air is blown out from the portion of the gap dimension L provided between the commodity receiving base 101 and the lower roller 103.

  In the present embodiment, the discharge air passage side of the blower fan 400 is made to act on the object to be cooled. However, the discharge air passage side is not necessarily used for reasons such as restrictions on the air passage structure and countermeasures for air blowing noise. In some cases, it is possible to use the intake air passage side.

  Next, the non-contact type temperature detection means 110 that is a temperature detection means for detecting the temperature of the can product 18 will be described.

  The non-contact type temperature detecting means 110 (for example, an infrared sensor) is disposed in the vicinity of the lower roller 103 at a substantially middle portion in the longitudinal direction (width direction) of the commodity receiving base 101. Since the can product is disposed in contact with the lower roller 103, the distance between the can product and the non-contact temperature detecting means 110 can be kept substantially constant regardless of the outer diameter of the can.

  Further, the non-contact type temperature detecting means 110 is arranged in the substantially intermediate portion in the longitudinal direction of the product receiving base 101. However, the non-contact temperature detecting means 110 may be arranged in the vicinity of the lower portion in the longitudinal direction of the arranged product receiving base 101. The measurement accuracy of the can surface temperature can be improved by shifting.

  This is the positional relationship of the induction heating coil 102 with respect to the can product, and the vicinity of the central portion in the longitudinal direction of the can product is located at the substantially central portion of the induction heating coil 102 due to the arrangement configuration of the induction heating coil 102 with respect to the product receiving base 101. For this reason, the temperature tends to be the highest, and tends to be lower toward the end in the longitudinal direction of the can product.

  Therefore, since the rate of change in the can surface temperature is larger at the center of the can product, the non-contact temperature detecting means 110 capable of detecting a wide temperature range with high accuracy is required. However, in order to increase the accuracy of the non-contact temperature detecting means 110 so that the can product can be detected at an appropriate temperature and the heating can be controlled, the accuracy is increased by using the non-contact temperature detecting means 110 having a narrow measurement temperature range. The non-contact type temperature detecting means 110 is required in the vicinity of the lower part in the longitudinal direction of the product stand 101 which is a position shifted from the center of the can product, that is, the position corresponding to the end of the induction heating coil 102. By arranging it, the measurement accuracy of the can surface temperature can be improved, the safety of burns and the like due to overheating can be improved, and the deterioration of quality due to the slimy product can be prevented.

  As described above, the induction heating device for can products according to the present invention can stably perform uniform heating with stable quality regardless of the size of the can product, and can be efficiently worn by rotation and contact. Vending machines and portable cans can be added to the structure that can ensure quality against deterioration due to heating, etc., and can be carried out to the outside without clogging can products in the device after heating. Widely applicable as a heating device.
