【Example】

 Next, an embodiment of the present invention will be described with reference to FIG. 1. The heating device shown here is installed, for example, inside a vending machine for canned beverages, and is arranged in a fixed state with an inclination. A hollow high-frequency induction heating body (heating body) 10, a hollow rotating body 11 inserted along a hollow portion 10a penetrating in the axial direction of the heating body 10 and rotatably equipped; The hollow rotating body 11 is provided with a canning support roller 12 that receives the canned food a supplied into the hollow rotating body 11 at the lower end opening 11b side of the hollow rotating body 11, and the canned food a is supplied into the hollow rotating body 11 to rotate the canned food a. It is configured to heat while heating.

The inclination angle θ of the heating body 10 and the hollow rotating body 11 with respect to the vertical line allows the canned food a to fall freely during supply and discharge of the canned food a without requiring any special auxiliary means. It is the angle at which the inside of the hollow rotating body 11 is discharged or is discharged from the hollow rotating body 11, and the contact pressure based on the self-weight of the canned a acting on the inner wall surface of the hollow rotating body 11 when the canned a is rotated and heated becomes necessary and sufficient. Although it depends on the friction coefficient of the inner peripheral surface of the hollow rotating body 11, it is preferable to set the angle in the range of 15 ° to 75 ° as an example. That is, if the inclination angle θ is larger than 75 °, it becomes difficult to supply and discharge the canned food a into the hollow rotating body 11 by free fall, and if it is smaller than 15 °, the hollow rotating body 11 can be discharged. This is because the contact pressure due to the self-weight of the can a on the inner peripheral surface becomes small, and it becomes difficult to transmit the rotational force due to friction between the two. The inclination angle θ is preferably set in the range of 55 ° to 65 °. By doing so, the canned food a can be smoothly dropped into the hollow rotating body 11 by free fall and discharged, and the rotational force can be reliably transmitted from the hollow rotor 11 to the canned food a. ..

The hollow rotating body 11 is a cylindrical member that is longer than the heating body 10 and is open at both ends in the axial direction. The hollow rotating body 11 is a portion on the upper end opening 11 a side. Are concentrically inserted inside the heating body 10 in a state of protruding from the upper end of the heating body 10. A pair of ball bearings 13 are attached to the portion of the hollow rotating body 11 on the upper end opening 11a side at appropriate intervals in the axial direction. The hollow rotating body 11 is installed inside the vending machine by the ball bearings 13. It is rotatably supported by a fixed member 14 arranged in a fixed state. A driven pulley 15, which is a rotated member, is attached between the ball bearings 13 on the outer peripheral surface of the upper opening 11a side. The hollow rotating body 11 is preferably configured so that the canned food a can be induction-heated by the heating body 19 and has appropriate slidability and strength. Among the materials, epoxy glass is preferable.

A motor 16 as a rotary drive source is arranged near the hollow rotating body 11, and a drive pulley 17 fixed to a rotary shaft 16 a of the motor 16 and the driven pulley 15 are provided between the drive pulley 17. The belt 18 is stretched around.

Further, the canned supporting roller 12 is provided on the roller mounting shaft 12a that reciprocates along the axial direction orthogonal to the axis of the hollow rotating body 11 at the lower end opening 11b side of the hollow rotating body 11. It is rotatably mounted with its movement restricted in the axial direction, and is configured to be capable of contacting the peripheral edge of the bottom of the can a and the opening edge of the lower end opening 11b of the hollow rotating body 11. The canned supporting roller 12 absorbs the impact force of the canned product a when the canned product a is supplied into the hollow rotating body 11 and prevents the roller mounting shaft 12a from being overloaded, and the canned support roller 12 can be rotated. In order to assist the transmission of the rotational force of the body 11 to the can a, it is formed of a material having an appropriate elasticity and a coefficient of friction, for example, urethane rubber. The canned support roller 12 has a tapered portion 12b in contact with the peripheral edge of the lower end opening 11a of the hollow rotating body 11 to prevent friction and wear due to the difference in peripheral speed. Although not shown, a reciprocating mechanism is provided at the end of the roller mounting shaft 12a.

Next, the operation of the canned food heating device configured as described above will be described. The canned goods supporting roller 12 advances to the lower side of the lower end opening 11b of the hollow rotator 11 and stands by, and the canned goods a requested by the purchaser is supplied into the hollow rotator 11 from a canned goods holding portion (not shown). Then, the canned food a is held in the hollow rotating body 11 by being prevented from falling off from the hollow rotating body 11 by the canning support roller 12. In this state, when the heating body 10 is energized and the motor 16 is driven to rotate the hollow rotating body 11, the hollow rotating body is contacted at the contact portion b between the inner wall surface of the hollow rotating body 11 and the outer wall surface of the can a. The rotating force of 11 is frictionally transmitted to the canned food a, and the canned food a is rotated uniformly and rapidly while the hollow rotating body 11 is rotated. At this time, the canned article supporting roller 12 receives a rotational force from the opening edge of the lower end opening 11b of the hollow rotating body 11 and transmits this rotational force to the canned article a to assist the rotational driving of the canned article a.

When the canned food a is heated to a predetermined temperature after a predetermined time has elapsed, the canned food support roller 12 retracts from the lower end opening 11 b of the hollow rotating body 11, and the heated canned food a is supported from below. And is discharged downward from the hollow rotating body 11. After that, the canned goods supporting roller 12 advances again toward the lower end opening portion 11b side of the hollow rotating body 11 and becomes ready to receive the succeeding canned goods a.

When the can supporter 12 is configured to receive and discharge the can a as described above, the heating body 10 can be mounted in a fixed state, so that a large installation space is required for the heating body 10. There is no. Further, even when a plurality of cans a are continuously heated, a series of heating operations can be performed in a short time.

The present invention is not limited to the above-described embodiment, and for example, the canning support roller 12 is reciprocated in the axial direction orthogonal to the axial direction of the hollow rotating body 11 by the roller mounting shaft 12a. Alternatively, the roller mounting shaft 12a may be swung below the lower end opening 11b of the hollow rotating body 11 to move the canning support roller 12 to and from the canning a. Further, when a sufficient rotational force is transmitted from the hollow rotating body 11 to the canned food a, the canned food support roller 12 may be brought into contact with and separated from the canned food a only. Further, a gear transmission mechanism may be used to transmit the rotational force from the motor 16 to the hollow rotating body 11. Furthermore, the hollow rotating body may be arranged in a vertical position if the rotational force for the canning is sufficiently transmitted by the canning supporting roller. Further, since the hollow rotating body does not perform the tilting motion in this invention, the rotational force to the hollow rotating body may be transmitted to an appropriate portion other than the upper end portion.

[0020]

[Effect of the device]

 As described above, in the canned food heating device of the present invention, the canned goods supporting roller is arranged at the lower end opening side of the hollow rotating body to receive the canned goods, and the canned food supporting roller is retracted from the lower end opening portion of the hollow rotating body. Since the cans are discharged by means of the can, it is possible to install the heating element, the hollow rotating element or its rotary drive in a fixed state, and as a result, the mechanism is simplified and the required installation space is reduced. You can Further, since the cycle time of receiving, heating and discharging cans is shortened, a plurality of cans can be continuously heated and delivered in a short time.
