Description

  The present invention relates to the safety of an induction heating type can product heating apparatus equipped with an induction heating type can product heating apparatus in a vending machine.

  Conventionally, an induction heating coil used in an induction heating device itself is insulated into a double layer with an insulating layer to form a safe induction heating coil, for example, disclosed in Patent Document 1.

  FIG. 19 is a cross-sectional view of a conventional induction heating device described in Patent Document 1.

  As shown in the figure, a ceramicized silicon tape insulating layer 2 is wound around a conductor 1, a glass cloth tape insulating layer 3 is further wound thereon to form a coil, and a varnish layer 4 is formed on the entire coil.

  By doing in this way, sufficient electrical insulation and mechanical strength are obtained on the surface of the coil, and moisture resistance is obtained by the varnish layer.

  Thus, according to the present invention, the induction heating coil has electrical insulation and heat resistance, and the reliability and safety of the induction heating device can be improved.

  FIG. 20 is a configuration diagram of the induction heating type can product heating apparatus described in Patent Document 2.

  As shown in the figure, the can product 5 is received and held in the coil cover 6 in a horizontal posture, and the induction heating coil 7 wound around the outer periphery of the coil cover 6, the high-frequency power source 8 that is energized, and the coil cover 6. A non-contact temperature sensor 10 is provided in the detection hole 9, and a control unit 10 a that takes in a temperature signal of the can product 5 detected by the temperature sensor 10 and controls energization of the induction heating coil 7.

  Referring to the operation of FIG. 20, the temperature sensor 10 detects the initial temperature of the can product 5, determines the energization time required for heating to an appropriate temperature based on the temperature signal of the initial temperature, and starts induction heating by timer control. Immediately after the energization time has elapsed, the temperature of the can product 5 is checked, and if the can product temperature reaches an appropriate sales temperature, induction heating is stopped and terminated. In addition, during heating before the energization time elapses, the can product is abnormally overheated, and if it is determined that the appropriate sales temperature has been exceeded, the energization is immediately stopped.

By the above operation, it is possible to deal with abnormal overheating and underheating of can products, and to provide the products by induction heating to an appropriate sales temperature.

  However, in the case of the induction heating device of Patent Document 1, an insulating layer is provided on the induction heating coil to reinforce the mechanical strength, electrical insulation, and heat resistance of the induction heating coil itself. There is no suggestion about the configuration of the connection wiring connected to the high-frequency power supply. When the connection wiring is damaged, the induction heating coil becomes unusable due to short-circuit current, or it is used due to high voltage leakage. There was a problem that a person touched and a disaster occurred.

  In addition, the shape of the induction heating coil 20 is not limited to the substantially circular arc shape or the bowl shape as described above, but may be any shape that can receive and hold the can product 18 in the inverted posture and perform appropriate heating.

  The product cradle 19 is formed of a non-magnetic material such as resin, and a flange portion 19a is formed on the periphery of the product cradle 19 toward the back surface, and the back surface of the product cradle 19 is surrounded by the flange portion 19a. A space portion 19b is formed. The induction heating coil 20 is formed in the space 19b. The product cradle 19 is fixed to the outer frame 24 forming the induction heating device 17 with screws or the like.

  In addition, since the material which forms the goods stand 19 will contact and slide with rotation operation of the can goods 18, when it is the case of resin, it is high density polyethylene etc. which have the characteristic of low friction and low wear, for example It is preferable to form with resin.

  The induction heating device 17 is formed so as to cover the periphery with an outer frame 24. Specifically, a back wall 24a for fixing the back surface of the product receiving base 19, a bottom wall 24b for fixing the lower surface of the product receiving base 19, and side walls 24c that form both side walls of the induction heating device 17 on both ends of the product receiving base 19. 24d and a front wall 24e corresponding to the back wall 24a. Specifically, as shown in the figure, it is installed so that the back side of the product stand 19 can be fixed to the side wall 24a and the bottom wall 24b of the outer frame 24, and the upper part of the product stand 19 is arranged along the side wall 24a. 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 the can product 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.

  The arrangement relationship of the induction heating device 100 with respect to the vending machine main body 11 and the outer door 12 is the same as that in the first embodiment, and is omitted.

  Further, the arrangement position in the height direction of the induction heating device 100 is the same as that in the first embodiment, and the arrangement position in the height direction of the commodity induction heating control unit 502 is at a position below the commodity outlet 16. Has been placed. Further, the arrangement position of the induction heating device 100 in the left-right direction is configured between the coin collection box 503 that collects coins and the product outlet 16.

  Below, the heating structure by the induction heating apparatus 100 is demonstrated.

  The induction heating apparatus 100 includes a product cradle 101 having a substantially chamfered cross section for receiving and holding the can product 18 in an inverted position, an induction heating coil 102 wound around the back surface of the product cradle 101, and the vicinity of the 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 base 101 is formed of a non-magnetic material such as a resin, and a substantially rectangular tempered glass plate 500 is fitted in a portion where the can product 18 contacts 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. An induction heating 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, it is possible to prevent a decrease in reliability due to heat generation of the induction heating coil 102.

  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.

  In FIG. 15, the portion of the core member 108 in which the rubber member 103c is formed in a spiral shape is formed as a groove portion 108b that is one step lower than the protrusion 108a of the core member 108, and the rubber member is formed in the groove portion 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.

  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 under the product 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 can product 18 is thrown into the product receiving base 101 of the induction heating device 100 from above, the lower roller 103 is rotationally driven by the lower roller drive motor 111 via the belt as in the first embodiment. .

  When the user operates a product selection button for selecting a hot product configured on the outer door of the vending machine, this operation signal is provided on the back surface of the outer door 12 of the vending machine 11 and above the product outlet 16. Received by the main control unit 501 of the entire vending machine 11, is arranged independently of the main control unit 501, and is transmitted to the product induction heating control unit 502 disposed below the product outlet 16, so that the induction heating coil 102 receives high frequency An electric current is applied, and the lower roller 103 that rotates the can product 18 is rotated. Then, the product preheated to about 35 ° C. in which the product is not deteriorated in the vending machine main body 11 is unloaded from the unloading means (not shown) and is put into the product receiving base 101 in an inverted posture, and the can product 18 is induction-heated. . Then, an appropriate temperature is detected by a non-contact temperature detecting means 110 described later, and the power supply to the induction heating coil 102 and the lower roller 103 are stopped.

  When the lower roller 103 is rotated, the rubber member 103c is in contact with the can product 18, so that the can product 18 can be rotated without being idle on the product receiving base 101, 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 can be 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 attitude control member 200 provided in the upper part of the product receiving base 101 of the induction heating apparatus 100 is the same as that in the first embodiment, and the configuration, operation, and action are omitted. The configuration of the upper roller 201 that operates the attitude control member 200 is the same as that of the lower roller 103 of the second embodiment, and is omitted.

  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 product is carried out by the same operation as in the first embodiment, and will be specifically omitted. 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. 13, the outer frame 106 is configured with pusher means 301 that pushes out the carry-out member 300 at the standby position so as to interlock 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.

  After the can product is maintained in the inverted posture on the product receiving base 101 by the operation of the attitude control member 200, a heating operation is performed, and after heating at an appropriate temperature, the product is carried out of the product receiving base 101 by the carry-out member 300. Operation is performed.

  During the heating operation, the lower roller 103 rotates and the rubber member 103c comes into contact with the can product to rotate 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.

  Therefore, since the can product can be automatically taken out to the outside, the user does not need to put his / her hand into the induction heating apparatus 100 and take out it, 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 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.

  Further, an opening 504 communicating with the product outlet 16 is formed at the end of the product receiving base 101 of the induction heating apparatus 100, and an opening / closing member 505 that is movable in the vertical direction for opening and closing the opening 504 is formed. . The structure, operation, and action of the opening / closing member 505 are the same as those in the first embodiment.

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

  As shown in FIG. 16, a drive unit 100b that houses a drive motor and the like is configured 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.

  In addition, the blower fan 400 can efficiently remove 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.

  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.

  Moreover, the structure in the coil case 101a which comprises the goods stand 101 in FIG. 18 is demonstrated.

  The resin-made coil case body 101b is divided into a coil storage area 600 for storing the induction heating coil 102 and a terminal storage area 601 on the left and right sides by a partition wall 604, and the terminal storage area 601 includes the induction heating coil 102. And relay terminal portions 602a and 602b that connect the product induction heating control unit 502 to each other and are connected by connection wirings 603a and 603b.

  The inside of the terminal storage area 601 will be described. The relay terminal portions 602a and 602b are defined by an inner wall 605 so as not to contact each other. The connection wirings 603a and 603b connected to the relay terminal portions 602a and 602b are formed in a double insulation structure.

  The inside of the coil storage area 600 will be described. In addition to the above description, two induction heating coil thermistors 105 a and 105 b for detecting the temperature of the induction heating coil 102 are arranged at substantially right and left symmetrical positions of the induction heating coil 102. The induction heating coil thermistors 105a and 105b are connected to and controlled by the product induction heating control unit 502.

  The operation and action of the configuration of the coil case 101a will be described.

  When the induction heating apparatus 100 is operated, a high voltage is applied to the coil storage area 600 and the terminal storage area 601 in the coil case, and the induction heating coil 102 becomes a high temperature of about 100 ° C. to 160 ° C. The storage area 601 is in a high temperature state. Therefore, since the coil storage area 600 and the terminal storage area 601 are partitioned by the partition walls 604 on the left and right, the induction heating coil 102 and the relay terminal part 602 can be prevented from being short-circuited, and the relay terminal part 602 Since it can come off and enter the coil storage area 600 to avoid contact with other components, safety can be ensured.

  The terminal storage area 601 is partitioned by the inner wall 605 so that the relay terminal portions 602a and 602b are not short-circuited by the resin inner wall 605, so that contact due to mounting variations during manufacturing can be prevented.

  In addition, since the connection wirings 603a and 603b connected to the product induction heating control unit 502 from the relay terminal units 602a and 602b have a double insulation structure, the coating strength is increased and the connection by contact with other parts is increased. It is possible to reduce damage to the wiring and tearing of the coated surface due to deterioration over time due to fluctuations in the outside air temperature especially in outdoor installations, ensuring safety to the user due to electric leakage or short circuit, or quality reliability of the induction heating device 100 Improvements can be ensured.

  Next, the inside of the coil storage area 600 will be described. Since the induction heating coil 102 is in a high-temperature state as described above during product heating, the induction heating coil 102 is always cooled by forced cooling, but the safety is improved. Therefore, the induction heating coil thermistor 105 is monitored. In the case of the embodiment, two induction heating coil thermistors 105a and 105b are arranged on the left and right sides of the back surface of the induction heating coil 102, and the temperature is detected by both induction heating coil thermistors 105a and 105b.

  For example, when one induction heating coil thermistor 105a out of the induction heating coil thermistors 105a and 105b exceeds the reference temperature 120 ° C., the energization to the induction heating coil 102 is stopped. Start. As described above, when both the induction heating coil thermistors 105a and 105b are not below the reference temperature, the operation is stopped, so that disasters such as smoke and ignition can be prevented and safety can be improved.

  Even if one induction heating coil thermistor 105a runs away and proper temperature detection becomes impossible, the temperature can be controlled by the other induction heating coil thermistor 105b, so that safety can be maintained.

  In addition, the induction heating coil thermistors 105a and 105b are both connected to and controlled by the product induction heating control unit 502, but only one induction heating coil thermistor 105a is connected to the main control unit 501 of the vending machine, Even if the induction heating coil thermistor 105a runs out of control and the induction heating coil thermistor 105b cannot be controlled by making the control units of the induction heating coil thermistor different, the induction heating coil thermistor 105a is different from the main controller. Since it is controlled at 501, the control can be performed normally, and it is possible to prevent both of the induction heating coil thermistors 105 a and 105 b from being unable to detect the proper temperature due to the runaway of the control unit. Can increase the sex.

  In the present embodiment, the installation positions of the two induction heating coil thermistors 105a and 105b are set substantially symmetrically with respect to the longitudinal direction in which the can product is inverted. If there is a more preferable representative position in view of the surrounding temperature distribution, it is not limited to this, and if there is no problem in detection accuracy, it may be arranged vertically or an induction heating coil even if it is not in an accurate symmetrical positional relationship Arbitrary arrangements having a positional relationship with 102 in between are also possible.

  Moreover, if the shape of the induction heating coil 102 is a winding shape that extends in accordance with the inversion direction of the can product, it is a preferable direction in terms of heating efficiency, but it is not necessarily wound in an elliptical shape as in the present embodiment. However, the shape may be determined comprehensively in combination with other structural, performance, and quality factors. Therefore, the installation position of the induction heating coil thermistors 105 a and 105 b may be determined without being limited by the relationship with the shape of the induction heating coil 102.

  As described above, the induction heating apparatus for can products according to the present invention can stabilize the heating posture regardless of the size of the can products, can efficiently perform uniform heating with stable quality, and can improve the safety of the induction heating coil. In addition to the fact that the secured configuration can be added, it can be widely applied as a vending machine or a portable can heating device.
