として公知である。As a product heating device described above, a high-frequency induction heating device is provided near the product outlet, and when a hot product is selected at the time of sale, can products taken out of the product storage section in the machine are guided to the high-frequency induction heating device. Japanese Patent Application Laid-Open No. Sho 54-699 discloses a method in which the product is heated and then sent out to the product outlet.
It is known as

容器内に収容した缶商品を間接的に加熱して温める。ま
た、誘導加熱コイルの通電で生成した磁束の一部(漏洩
磁束)は直接缶商品と鎖交して缶自身を誘導加熱する。Such a product heating device is composed of a cylindrical heating container having a vertical axis made of a ferromagnetic metal material, and an induction heating coil wound around the outer periphery of the heating container. The can product rolled and carried out in the above is changed from the inverted position to the vertical position by another handling mechanism and guided into the heating vessel, where a high-frequency current is applied to the induction heating coil. As a result, the heating container itself is induction-heated, and the heat indirectly heats and warms the can goods stored in the container. In addition, a part of magnetic flux (leakage magnetic flux) generated by energization of the induction heating coil is directly linked with the can product and induction-heats the can itself.

缶商品との間に空気層を介した大きな伝熱抵抗が加わ
り、このために加熱効率が低下して中身飲料を適温に加
温する加熱所要時間が長くかかる。By the way, as described above, in the conventional product heating apparatus, as a heating mode of the product, first, the tubular heating container itself arranged on the vertical axis is heated by energizing the induction heating coil, and the heat is stored in the heating container. Indirect heating, which heats the contents of the beverage by transferring heat to the main body, and at the same time, induction heating of the canned product itself is adopted. Disadvantages. (1) Since the indirect heating mode is mainly used, a large heat transfer resistance is applied between the heating container and the canned product via an air layer, thereby lowering the heating efficiency and keeping the content beverage at an appropriate temperature. It takes a long time to heat for heating.
(2)筒形加熱容器の径寸法によってここに適合する缶

ない。(2) The size (diameter) of a can product conforming to the diameter of the cylindrical heating container is uniquely determined, and a can product of a larger size cannot be accommodated in the heating container, and The same product heating device cannot be used for can products of various sizes, for example, the size of a can product having a large size (air space) between the can and the heating container reduces the heating effect.
(3)機内の商品収納部から転動式に搬出された缶商品

ドリング機構が必要となり、機構,操作が複雑化する。(3) In order to load the rolling product from the product storage section inside the machine into the product heating device, a handling mechanism for changing the posture of the can product from the inverted position to the vertical position and introducing the product into the heating container. Is required, and the mechanism and operation are complicated.

め、さらに接着剤,ないしろう付けにより液密に封止し
ており、導電性について見るとこの継目部分の電気抵抗
は他の部分よりも高くっている。(4) Since the induction heating coil is wound around the outer periphery of the cylindrical heating container, the magnetic lines of force interlinking with the can products contained in the heating container pass in the direction of the can axis. Therefore, the eddy current flowing in the can itself due to the electromotive force due to the linkage with the magnetic field lines flows along this loop with the periphery of the can being a closed loop. On the other hand, the can structure of a can product is a structure in which a can lid is connected to both ends or one side of the can body, and between the can body and the can lid, and in the case of cans other than the drawn can body, the periphery of the can body. There are seams on the surface. By the way, this seam is folded and folded in a can material, and furthermore, it is sealed in a liquid-tight manner with an adhesive or brazing. In terms of conductivity, the electric resistance of this seam is higher than that of other parts. .

ることがある。For this reason, when eddy current flows along the circumference of the can by interlinkage with the magnetic field lines passing in the can axis direction, the seam is locally abnormally heated by the eddy current, and the seam is peeled off depending on the situation. Or Also, with the overheating occurring at the can lid joint, the air enclosed in the residual space at the top of the can is overheated and the pressure inside the can rises abnormally, and as a result, the can itself was punctured. Trouble may occur.

とを目的とする。The present invention has been made in view of the above points, and solves the above-described problems in the conventional product heating apparatus, can efficiently and directly heat products of various sizes, and requires a special handling mechanism. It is an object of the present invention to provide a product heating apparatus which can load and heat a product on a product heating apparatus in a product delivery path while keeping the product in an unloading position without performing the above.

継目部分が誘導加熱コイルの領域の外に位置する状態で
缶商品を誘導加熱するものとする。In order to solve the above problems, in the product heating device of the present invention, a gutter-shaped product receiving tray made of a non-magnetic material that receives and holds can products in an inverted posture, and this product receiving tray is An induction heating coil which is independently configured and installed on the lower surface side of the product receiving stand, wherein the longitudinal dimension of the induction heating coil is selected to be shorter than the axial length of the can product, and the can product is placed in an inverted posture. It is assumed that the can product is induction-heated in a state where the seam portion between the can body and the can lid at both ends of the can is located outside the region of the induction heating coil.
また、前記の誘導加熱コイルは、その長手寸法が缶商
品の軸長寸法よりも短小に選定するのがよい。Further, it is preferable that the above-mentioned induction heating coil is selected such that its longitudinal dimension is shorter than the axial length of the can product.

とができる。In the above configuration, the product heating device is disposed, for example, at the bottom of the product outlet. Here, when a can product taken out of the product storage section of the machine by the sales order is rolled and carried out to the product exit via the unloading shooter, the product first falls onto the product receiving tray of the product heating device and is placed in the inverted position. Accepted and held as is. This process does not require any special handling mechanism. Here, if the products are refrigerated in the product storage section, when the hot products are not selected, the customer can take out the cold can products directly from the receiving stand through the product outlet.

ない。On the other hand, if a hot product is selected, the induction heating coil is supplied with power from a high-frequency power supply and energized according to a command from the controller, and the magnetic field lines of the coil generated thereby are linked to the can product in a direction perpendicular to the can axis. As a result, the eddy current generated in the can does not flow through the entire circumference of the can as a closed loop, but flows through the surface of the can in a small local loop, and directly inductively heats the can with the Joule heat. If the can material is made of a magnetic material such as a tin can, heating due to hysteresis loss due to linkage of lines of magnetic force is also added. Here, the size of the induction heating coil is selected to be slightly smaller than the axial length of the can product in advance, so that the seam between the can body and the can lid is directly subjected to induction heating and locally abnormally heated. Never be.

した缶自体がパンクすると言った不測なトラブルの発生
が回避できる。Furthermore, since the can product is placed in the inverted position and is subjected to induction heating, the remaining space in the can moves to the upper surface side of the can body opposite to the heating surface. Therefore, the heat generated in the can is efficiently transferred to the liquid beverage contained in the can, so that the liquid beverage can be heated to an appropriate temperature in a very short time, and the air in the remaining space in the can is also opposite to the induction heating surface. As a result, there is no direct heat transfer, thereby avoiding the occurrence of an unexpected trouble such as a puncture of the can itself where the pressure in the can has risen to a dangerous state.

(直径)の缶商品にも対応可能できる。When the heating is completed, the customer can directly take out the can goods placed on the goods receiving stand of the heating device through the goods take-out port, and in this process, there is no need for a handling mechanism. In addition, since a method is adopted in which can products are received and held in the product receiving stand in the inverted position, by selecting the gutter diameter of the product receiving stand sufficiently large in advance, can products of various sizes (diameters) can be manufactured. Can also be supported.

短く選定されている。First, in FIG. 1, 1 is a product heating device, and 2 is a can product loaded in the product heating device 1. Here, the product heating device 1 is configured by combining a product receiving table 11 and an induction heating coil 12, and the product receiving table 11 is a semicircular gutter-like body having an open upper surface. Made of magnetic, non-conductive material. On the other hand, the induction heating coil 12 is formed as a saddle-shaped air-core coil mounted at the center of the lower surface of the commodity receiving table 11, and is connected to a high-frequency power source (not shown).
The longitudinal dimension A of the induction heating coil 12 is selected to be shorter than the axial length dimension B of the can product 2 by a dimension C from both left and right ends.

熱により加熱されることになる。With such a configuration, when the canned product 2 is placed on the product receiving stand 11 in an inverted posture, and a high-frequency current is applied to the induction heating coil 12 in this state, the magnetic force lines φ are formed around the coil as shown in FIG.
Is generated. The lines of magnetic force φ penetrate the non-magnetic material receiving table 11 and interlink with the can product 2 in a direction orthogonal to the central axis (longitudinal direction) of the can body 21. Here, if the can product 2 is a tin can as described above, since tin (a mild steel plate subjected to tin plating) is a magnetic material, most of the lines of magnetic force φ are as shown in the figure. Concentrate through the inside along the 21 walls. As a result, an electromotive force is induced inside the can body 21 to cause an eddy current of a small loop to flow as shown by the symbol i, and this eddy current generates Joule heat, and at the same time, hysteresis due to linkage with the magnetic field line φ. Heat due to the loss is also added, and the heat generated here is transferred from the can wall of the can body 21 to the liquid beverage 24 contained in the can, thereby heating the liquid beverage. When the product can is made of a non-magnetic material such as an aluminum can, the distribution of the lines of magnetic force φ with the can body changes slightly, and there is no heating due to hysteresis loss.
An eddy current of a small loop similar to the above flows and is heated by the Joule heat.

るおそれはない。Moreover, in this case, the can 2 is placed in the inverted position,
11, the remaining space 25 in the can has moved to the upper surface side of the can body 21 on the side opposite to the induction heating surface, and the upper surface side of the can body 21 from the direction of linkage of the magnetic force lines φ. No eddy current flows, so that the air sealed in the remaining space 25 is not unnecessarily heated and the pressure in the can is not excessively increased. Similarly, since the longitudinal dimension A of the induction heating coil 12 is shorter and smaller than the axial length dimension B of the can product 2, the can body 21 at both ends of the can is provided.
There is no danger that the joint between the can and the can lids 22 and 23 will be locally abnormally heated.
また、缶胴21の周面上の継目(ブリキ缶)について
も、缶商品2が商品受台11に載置された状態で缶胴21の
継目が誘導加熱面から外れていれば磁力線φとの鎖交が

常加熱されることがない。Also, regarding the seam (tin can) on the peripheral surface of the can body 21, if the seam of the can body 21 is displaced from the induction heating surface in a state where the can product 2 is placed on the product receiving tray 11, the line of magnetic force φ , No eddy current is generated in this joint portion, and no local abnormal heating occurs.
