Description

TECHNICAL FIELD [0001] The present invention relates to an induction punching and sealing apparatus,

The present invention relates to a sealing apparatus for a container, and more particularly, to an induction type punching and sealing apparatus capable of sealing at high speed and stably in a process of sealing an opening of a container through a film-type cover member.

Various types of containers made of synthetic resin, paper or the like are formed with the openings of the openings. After the contents of the liquid or gel are injected, the upper side is sealed. In order to prevent contamination of the liquid contents and long- Is generally sealed at the inlet.

Such a film cover material can be coupled to the container inlet in various ways. In such a container, as a method for sealing the opening of the container and the film cover member, heat sealing is generally applied in which sealing is performed by using a sealing head.

As a method of such a heat sealing, Japanese Unexamined Patent Application Publication No. 2004-250027 discloses a method in which a cover is conveyed by a cover pressing and conveying means disposed on the upper side of a container conveying means, The sealing head or the container itself is not moved up and down, so that high-speed sealing can be achieved.

On the other hand, Japanese Patent Application Laid-Open No. 11-20801 discloses a method for bonding a cover material and a container at a high speed by using heating by a heater cartridge and high-frequency dielectric heating or ultrasonic vibration heating in combination.

In addition, Japanese Patent Laid-Open Publication No. 58-19536 discloses a construction in which a metal body 2 is sandwiched between a heat-resisting elastic material 3 so as to be moved in parallel in synchronism with the upward movement of the container conveying belt conveyor 1 A high frequency induction heating coil 5 is disposed inside the heating press belt 4 and a cover material 7 covering the container 6 is sealed by high frequency induction heating of the heating press belt 4 .

The sealing apparatus of this type commonly employs a high-frequency sealing method. In this case, the reliability of the sealing and the efficiency of the high-speed sealing may depend on the performance of the high-frequency head.

[

It goes without saying that such a feed-in transfer portion 1650 and the discharge-transfer portion 1660 may be made as a single device.

The operation of the sealing apparatus 1000 according to the concept of the present invention as described above will now be described. The container set 20 transported to one side through the inlet / outlet unit 1200 is supplied to the fixing unit through the supply / The sealing means 1700 disposed below the bracket portion 1610 fuses the film cut by the high-frequency heating method to the inlet of the container 10. The number of vessels 10 that can be processed in a single sealing process can be determined by the number of sealing means 1700 disposed in the bracket portion 1610.

For example, the sealing means 1700 as viewed from one side may be arranged radially at intervals of 60 degrees, and such spacing may be optionally made.

As described above, since the sealing means 1700 disposed on the upper and lower sides of the bracket portion 1610 can perform separate processes at the same time, the concept of the present invention is that the cutting and sealing can be performed at the same time, It should be noted that this has advantages.

5 is a side sectional view showing the cutting part in more detail in the induction type punching and sealing apparatus of the present invention.

The film 1801 is guided by the leading-side roller 1830 on the front side to enter a predetermined portion of the cutting means 1510 and the remaining portion of the film 1801 is guided by the take- The collection takes place.

That is, the cutting unit 1510 operates between the take-out roller 1830 and the take-up roller 1840 to cut the film 1801 to form a cutting film, which will be described in more detail.

The cutting means 1510 includes a body portion 1511 for pressing the film 1801 at the lower end side and a cylinder portion 1513 connected to the upper side of the body portion 1511 and moving the body portion 1511 upward and downward. And a punching unit 1512 arranged to face the lower end of the body part 1511. As shown in FIG.

In the embodiment of the present invention, the cutting means 1510 is formed as a kind of punching device, but the present invention is not limited thereto, and various types of film cutting means can be applied.

6 is a side sectional view showing the sealing means of the induction type punching and sealing apparatus of the present invention in more detail.

As described above, the sealing part 1600 can be provided with a plurality of sealing means 1700 in the outer circumferential direction of the bracket part 1610 rotatable with respect to the housing 1110. In the embodiment, The sealing means 1700 may be arranged on both sides of the upper side and the sealing means 1700 may be arranged on both sides of the lower side in the opposite direction.

The sealing means 1700 includes a head portion 1710 for performing high frequency induction heating and a sealing cylinder portion 1720 for transferring the head portion 1710 in the longitudinal direction to adhere the film 1801 and the container 10 to each other. ).

The sealing cylinder part 1720 may be a piston device or a stepping motor, and the head part 1710 may be coupled to the end part to reciprocate in the longitudinal direction.

More specifically, the head portion 1710 includes a coil portion 1712 disposed inside the head portion 1710 and wound to be arranged in a circumferential direction and performing a high frequency induction function by control power, And a channel portion 1715 disposed inside the hollow portion of the coil portion 1712 to form a negative pressure and / or positive pressure with respect to the seating portion 1711, .

The coil portion 1712 may be wound up and down and / or in the left and right direction inside the head portion 1710 adjacent to the seating portion 1711. The coil portion 1712 receives an external control current, And functions to heat the film 1801, which is correctly seated on the seating portion 1711, with respect to the film 1711.

Specifically, the coil portion 1712 is electrically connected to an external high-frequency oscillator (not shown), and a high-frequency current input from the high-frequency oscillator generates heat to the seating portion 1711, And a ring-shaped magnetic body portion 1713 is preferably formed on the portion 1712 side. The magnetic body portion 1713 is configured such that the high frequency magnetic flux generated by the coil portion 1712 penetrates the magnetic body portion 1713 and induces an eddy current having a very high density so that the seating surface of the seating portion 1711 is heated will be.

The heating temperature of the seat part 1711 may be as long as it can reach a temperature at which the material constituting the container 10 and the cutting film can be fused and sealed, and the temperature can be controlled through the control of the energization time. For example, when a cutting film is formed of a polyethylene terephthalate resin or when a polypropylene resin is used as a sealant while a film is formed in a laminated structure, the film may be determined at about 180 to 220 ° C.

A supply passage 1717 for cooling the head portion 1710 may be provided inside the head portion 1710 separately from the flow passage portion 1715. The supply passage 1717 is preferably formed in the inner surface of the head portion 1710, It is possible to perform cooling by flowing in a space where the part 1712 is disposed.
