[Problems to be Solved by the Invention] When a large amount of cans are heated by the above apparatus, only a part of the cans is overheated in the circumferential direction, and the outer surface of the cans may be damaged. It was found that the rate of occurrence of this damage was high in cans with deformed trunks.

[0005] When the cause of the occurrence of this damaged can is investigated, in the case of a can that is inclinedly supported on the receiving plate or a can body in which the can body is deformed, the can does not rotate with the receiving plate and comes into contact with the induction heating device. It is known that this is due to excessive heating in the vicinity of the area where the heat is applied.

An object of the present invention is to provide an apparatus that eliminates the occurrence of the above-mentioned damaged cans.

[0007]

The present invention is based on the above knowledge, and comprises a high-frequency induction heating device, a receiving plate below the high-frequency induction heating device for receiving a can inserted into the heating device, A canning device for high-frequency induction heating, comprising: a rotating device for rotating the receiving plate; and a moving device for reciprocating the receiving plate from a location for receiving the can to a location where the can is discharged from the high-frequency induction heating device. A rotating / discharging device, having 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 can, A cylindrical body that is rotated by the rotating device with the inserted cans, and a lower end surface of the cylindrical body and an upper surface of the receiving plate that receives the cylindrical body are engaged with each other by unevenness meshing with each other. To, as the mobile device, 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]

According to the device of the present invention, the can is inserted into the cylindrical body, and the cylindrical body and the receiving plate rotate without slipping in a state of being engaged with the concave and convex, but at this time, the can can touch the induction heating device. Absent. Further, since the receiving plate is separated from the induction heating device by the downward arc motion, the above-mentioned concave-convex engagement is released without resistance, and the can is discharged from the high-frequency induction heating device as the receiving plate is lowered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view showing a partial cross section, and FIG.
FIG. 3 is a plan view of the receiving plate.

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

Reference numeral 11 denotes a cylindrical body which is rotatably mounted on a fixed member 10 provided on the induction heating device 2 via a bearing 11a and inserted into the heating device.
It has an inner diameter d into which canned A can be inserted, and extends to the lower end of the induction heating device.

Reference numeral 12 denotes a receiving plate for supporting the cylindrical body 11 together with the inserted can A, which is rotated by the rotating device 5 described above. Reference numeral 12a denotes a support shaft of the receiving plate 12, which is forcibly supported by a spring 12b, whereby the receiving plate can slide up and down.

A large number of irregularities (not shown) are provided at the lower end of the cylindrical body 11, while a large number of irregularities 121 are provided on the periphery of the upper surface of the receiving plate 12 so as to mesh with these irregularities. When the receiving plate 12 rotates, the cylindrical body 11 rotates integrally therewith.

Reference numeral 13 denotes a hanging plate fixed to the fixing member 10 (see also FIG. 2).
3 which supports the rotating device 5, the receiving plate 12, etc.
A pair of support plates, 15, 15 are lateral rotation shafts rotatably mounted on the support plates 14, 14 via bearings 15a, respectively, and 16 are rotation shafts 15, 15 via coupling members 16a, 16a. The fixed horizontal plate 17 is a connecting plate fixed to the lower surface of the horizontal plate and to which the motor 5d is attached. Reference numeral 5e denotes 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 vertically rotatably mounted on the horizontal plate 16 via the bearing 16a. ing.

The apparatus of the present embodiment has the above-described structure, and when the unevenness 121 of the receiving plate 12 is engaged with the unevenness on the lower surface of the cylindrical body 11 (FIG. 1), the can A is placed on the cylindrical body 11 from above. Then, the rotating device 5 is rotated to rotate the receiving plate 12. Accordingly, the cylindrical body 11 and the can A rotate with the receiving plate 12.
During this rotation, a predetermined current is supplied to the induction heating device 2 for a predetermined time, the can is heated to a predetermined average temperature as a whole, and then the rotation of the receiving plate is stopped.

Next, the cans are discharged. For this purpose, the receiving plate 12 is caused to move downwardly in an arc with respect to the heating device 2 (in the direction of the arrow Y in FIG. 1) so that the receiving plate 12 is engaged with the cylindrical body 11. solve.

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

The limit switch (not shown) is actuated by the rotation of the limit switch actuating member 20a attached to the other end of the other (right) rotating shaft 15 in FIG. At the lowest position, the movement stops.

With the above-mentioned movement of the receiving plate, cans in the induction heating device descend outside the device, fall off the receiving plate and fall.

Thereafter, the pulley 18 is rotated in the opposite direction to the above, and the receiving plate 12 makes an upward circular motion with respect to the heating device 2 (in the direction indicated by the arrow Z in FIG. 1), and meshes with the cylindrical body 11 again. At this time, the limit switch operating member 20b (FIG. 2)
As a result, the limit switch is actuated, and the receiving plate 12 collides with the lower surface of the cylindrical body and stops moving.
Is absorbed by the spring 12b.

The concavities and convexities provided on the lower surface of the cylindrical body and the periphery of the upper surface of the receiving plate may have a sawtooth shape or any other well-known mesh shape.

When the amount of movement of the receiving plate is accurately controlled by precise control of the rotation of the motor, the spring 12b can be omitted.

[0023]

According to the present invention, the can is rotated inside the cylindrical body and does not touch the induction heating device, so that the periphery thereof is uniformly heated and the outer surface printing is not damaged.
