[Problems to be solved by the device]

 When a large amount of cans were heat-treated with the above equipment, only a part of the cans were overheated in the circumferential direction and the outer surface printing was damaged, especially in cans with deformed can bodies. Was found to be high.

When the cause of occurrence of this damaged canned product was investigated, in the case of a canned product supported obliquely on the receiving plate or a canned body with a deformed can body, the canned product did not rotate together with the receiving plate and contacted the induction heating device. It was known that it was due to excessive heating in the vicinity of the touched area.

It is an object of the present invention to provide a device that eliminates the occurrence of damaged canned food.

[0007]

 The present invention is based on the above knowledge, and includes a high-frequency induction heating device, a receiving plate below the high-frequency induction heating device, which receives the cans inserted in the heating device, and a rotating device which rotates the receiving plate. And a moving device for reciprocating the receiving plate from a position for receiving the canned food to a position where the canned food is discharged from the high frequency induction heating device. A cylindrical body inserted into the high-frequency induction heating device and supported by the receiving plate, the cylindrical body having an inner diameter capable of inserting a canned product, and the inserted canned food product inside the high-frequency induction heating device. And a lower end surface of the cylindrical body that is rotated by the rotating device and an upper surface of the receiving plate that receives the cylindrical body are engaged with each other by unevenness that meshes with each other. And, the receiving plate, characterized in that established a mobile device to perform an arc reciprocating with respect to the high frequency induction heating device.

[0008]

[Action]

 In the device of the present invention, the canned article is inserted into the cylindrical body, and the cylindrical body and the receiving plate are rotated without slip in a state where the cylindrical body and the receiving plate are meshed with each other, but at that time, the canned article does not touch the induction heating device. .. Further, since the receiving plate is moved away from the induction heating device by the downward arc motion, the concavo-convex engagement is released without resistance, and the cans are discharged from the high frequency induction heating device as the receiving plate descends.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 is a side view partially shown in section, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a plan view of a receiving plate.

In the figure, A, 2, 5, 5a, 5b, 5c and 5d indicate the same components as those denoted by the same reference numerals in FIG.

Reference numeral 11 denotes a cylindrical body which is rotatably mounted on the fixing member 10 provided on the upper portion of the induction heating device 2 via a bearing 11 a and is inserted into the heating device. It has an insertable inner diameter d and extends to the lower end of the induction heating device.

Reference numeral 12 denotes a receiving plate that supports the cylindrical body 11 together with the canned food A inserted therein, and is rotated by the rotating device 5 described above. In addition, 12a is a support shaft of the receiving plate 12, and is forcibly supported by the spring 12b, which allows the receiving plate to slide up and down.

A large number of irregularities (not shown) are provided on the lower end of the cylindrical body 11, while a large number of irregularities 121 that mesh with these irregularities are provided on the peripheral edge of the upper surface of the receiving plate 12. When the backing plate 12 rotates, the cylindrical body 11 rotates integrally with it.

Reference numeral 13 denotes a hanging plate which is fixed to the fixing member 10 and hangs down (see also FIG. 2), and 14 and 14 are attached to the hanging plate 13 to support the rotating device 5, the receiving plate 12 and the like. A pair of support plates, 15 and 15 are lateral rotation shafts that are rotatably mounted on the support plates 14 and 14 via bearings 15a, respectively, and 16 is a rotation shaft 15 and 15 via connection members 16a and 16a. A horizontal plate 17 is fixed to the horizontal plate, and a connecting plate 17 is fixed to the lower surface of the horizontal plate and to which the motor 5d is attached. 5e is a vertical bearing in which the support shaft 12a of the receiving plate 12 is vertically slidably inserted and the driven pulley 5a is fixed. The vertical bearing 5e is rotatably mounted on the horizontal plate 16 through the bearing 16a. Has been done.

The device of the present embodiment has the above-mentioned configuration, and when the unevenness 121 of the receiving plate 12 meshes with the unevenness of the lower surface of the cylindrical body 11 (FIG. 1), the canned food A is transferred from above into the cylindrical body 11. Then, the rotating device 5 is rotated and the receiving plate 12 is rotated. Along with this, the cylindrical body 11 and the canned food A also rotate together with the receiving plate 12. During this rotation, a predetermined current is supplied to the induction heating device 2 for a predetermined time, the entire can is heated to a predetermined average temperature, and then the rotation of the receiving plate is stopped.

Then, the canned food is to be discharged. For that reason, the receiving plate 12 is caused to make an arc motion downward with respect to the heating device 2 (direction of arrow Y in FIG. 1) to engage with the cylindrical body 11. Solve.

That is, the pulley 18 attached to one end of the rotating shaft 15 on one side (left side) of FIG. 2 is driven by a motor (not shown), the belt 19 is rotated, and the receiving plate 12 is moved together with the rotating device 5. Move downward in the direction of an arc.

The limit switch (not shown) is activated by the rotation of the limit switch operating member 20a attached to the other end of the other (right side) rotary shaft 15 in FIG. Stops moving when is at the bottom.

With the above movement of the backing plate, the canned food inside the induction heating device descends outside the device, falls off the backing plate, and falls.

After that, the pulley 18 is rotated in the opposite direction to the above, and the receiving plate 12 makes an upward arcuate motion with respect to the heating device 2 (direction of arrow Z in FIG. 1) to re-engage with the cylindrical body 11. At this time, the limit switch is actuated by the limit switch actuating member 20b (FIG. 2), and the receiving plate 12 hits the lower surface of the cylindrical body and stops moving. At that time, the load applied to the receiving plate 12 is caused by the spring 12b. Be absorbed.

As the concavities and convexities provided around the lower surface of the cylindrical body and the upper surface of the receiving plate, saw-toothed shapes and other known meshed shapes can be applied.

The spring 12b may be omitted when the amount of movement of the receiving plate is accurately controlled by, for example, accurately controlling the rotation of the motor.
