Description

Technical Field [0001] The present invention relates to a heating apparatus for seaming part of cans,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heating device for a canming container, and more particularly, to a heating device capable of improving sealing performance of a can container by sealing a seaming portion of the can container by heating.

In general, a can container is used as a container for containing a juice, a concentrated liquid thereof, or a food such as kochujang or soybean paste.

This can container comprises a side plate 14 in the form of a rectangular barrel, an upper plate 16 having an inlet 15 and coupled to the upper portion of the side plate 14, And a lower plate 17 joined to the lower plate 17.

Here, the upper plate 16 and the lower plate 17 are coupled to the upper end and the lower end of the side plate 14 by seaming, respectively, so that the upper and lower seaming portions 11, 12 are formed.

A sealing compound 13 for sealing the can container 10 is applied to the inner side of the upper and lower side seaming portions 11 and 12.

The sealing compound 13 is applied to the joining portions of the side plate 14 and the upper plate 16 and the joining portion of the side plate 14 and the lower plate 16 before the seaming work is performed, It can be disposed inside the shimming portion 12.

However, in the related art, there is a problem that the sealing compound 13 is not brought into close contact with the inner surface of the upper shielding portion 11 and the lower shielding portion 12 after the seaming operation, and the sealing force of the can container 10 is lowered.

On the other hand, as a technique for solving such a problem, there has been proposed a technique in which a "leak-free metal container using a thermoplastic resin-coated steel sheet" (Korean Patent Publication No. 10-2011-0014763 (published on February 14, 2011, Is presented.

The prior art described above is based on the assumption that "a case where a body made of a steel plate coated with a thermoplastic resin is seamed without using a separate polymer compound in joining a top plate or a bottom plate, Quot; metal container ", which is a technique for preventing leakage of contents stored in a metal container by integrating the resin layer of the seaming portion.

As a result, in the prior art, the body, the top plate or the bottom plate are joined to the thermoplastic resin-coated metal container without the polymer compound, and the thermoplastic resin coated on the body, the top plate and the bottom plate is melted and integrated by heat treatment for a predetermined temperature and time, Although a complete seal is achieved,

A production cost is inevitably increased due to the use of a steel sheet coated with a thermoplastic resin, and a specific means for heating the seaming portion is not disclosed, and a separate technique for this is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,

And a second induction coil 340 installed in the second seating groove 331 of the second coil base 330.

The term "corresponding shape" does not mean only that the upper and lower seaming portions 11 and 311, or the lower seaming portion 12 and the second seating groove 331 have the same shape And the first and second seating grooves 311 and 331 have a size and a shape similar to the circumference of the can container 10.

The first and second coil bases 310 and 330 are spaced a predetermined distance from the upper end and the lower end of the can container 10 which has entered the heating space part 530, respectively.

Accordingly, the second coil base 330 is positioned below the support 600.

The first and second coil bases 310 and 330 are preferably made of a material having excellent insulation property such as bakelite.

The first and second induction coils 320 and 340 are wound around the first and second seating grooves 311 and 331 and are connected to a separately provided AC electric charger (not shown).

Accordingly, when a current is supplied to the first and second induction coils 320 and 340, a high-frequency magnetic field is formed around the first and second induction coils 320 and 340, And heat due to hysteresis loss is generated in the lower and upper chambers 11 and 12.

As a result, the heating unit 300 is heated by the high frequency induction heating method to heat up the upper and lower seaming portions 11 and 12, so that the sealing compound 13 (FIG. 13) applied in the upper and lower seaming portions 11 and 12 , See FIG. 1) are melted and closely adhered to the surfaces of the upper and lower seaming portions 11 and 12, thereby improving the sealing performance of the can container.

The heating unit 300 heats the upper and lower shaping portions 11 and 12 by a high frequency induction heating method so that only the upper and lower shaping portions 11 and 12 of the can container 10 are locally heated It can be heated quickly.

The transfer unit 400 is for transferring the can container 10 disposed in the entry space part 510 to the heating space part 530 and the discharge space part 520 step by step,
