When the heater 411 is lowered, the pressure rubber member 413 is also lowered so that the film 310 is not moved when the film is cut by pressing the film 310 placed between the pressure rubber member 413 and the auxiliary rubber member 236. To facilitate cutting.

Looking at the operation of the present invention configured as described above are as follows.

First, while the heater 411 is preheated by supplying power, the user opens the tray 200 by grasping the handle 205 of the tray 200 and pulling it forward.

After the tray 200 is opened as shown in FIG. 3C, the container containing the food is placed in the container seating hole 220, and the film transporting means located at the rear end of the container seating hole 220 by pulling the film 310 wound on the roll. It is positioned between the first rubber magnetic plate 251 and the second rubber magnetic plate 255 (250). At this time, the first rubber magnetic plate 251 and the second rubber magnetic plate 255 are forcibly spaced apart by a predetermined separating member 270.

In this state, when the tray 200 is pushed in as shown in FIG. 3B, the first rubber magnetic plate 251 and the second rubber magnetic plate 255 that are forcibly separated by the separating member 270 are released, and the first is removed. And the second rubber magnetic plates 251 and 255 are stuck due to mutual attraction. In this case, the film 310 is sandwiched between the first and second rubber magnetic plates 251 and 255 to move together with the tray 200, and the wound film 310 is released to the inlet of the tray 200 through the top of the container. Will be covered.

In this state, when the user presses the start packing button located on the front of the main body 100, the controller rotates the drive motor 450, and the cam 460 gradually rotates vertically as the drive motor 450 rotates. Will descend.

Accordingly, the cam contact member 470 is pressed down on the cam 460 and the shaft 480, the heater cover 410, and the heater 411 connected to the cam contact member 470 are also lowered.

While the heater cover 410 is lowered and the pressure rubber member 413 contacts the auxiliary rubber member 236 of the tray 200, the film 310 is pressed while the heater 411 is also pressed with the pressure rubber member 413. In contact with each other, the film 310 interposed therebetween is thermally fused to package the container. In addition, when the film 310 is heat-sealed, the controller controls the rotation of the driving motor 450 such that the heater 411 presses the film 310 for about 2 seconds.

In addition, the film 310 is thermally fused to the container, and the cutter 415 around the heater 411 is also cut to the film 310 while cutting the film 310. That is, the cutter 415 cuts the area of the film 310 between the heater and the pressurized rubber member 413.

As the cam 460 is rotated and returned to its original position after packaging the container as described above, the heater 411 is returned to the original position by the extended spring 440.

As such, when the container packaging is completed, the controller notifies the user of the container packaging completion time through a predetermined display means installed in the front of the main body 100.

As described above, in the present invention, when the film is fused to the vessel, the pressurization operation method of the heater is simplified. That is, the motor 450 does not use power transmission means such as a general timing belt, a pulley, and a shaft. The cam 460 is directly connected to the cam 460 to simplify the power transmission means to eliminate the extraneous parts, simplifying the economic effect, function and structure, and disassembling the assembly in the event of A / S generation. It can be done easily. As a result, the complex power transmission method of the existing company can be improved and the manufacturing cost of the equipment can be lowered by combining and simplifying the components in the right place.

In addition, the existing company adopts the method of coating rubber on the die casting casting part upper part in the container seating part supporting the container, and the overlap investment of the die casting casting mold and the silicone rubber mold has been made. Unnecessary loss occurred.

However, in the present invention, by manufacturing the mold frame (injection) to support the actual crimping portion rubber and the rubber separately, the pressing rubber member 232 and the auxiliary rubber member 236 into the groove of the mold frame 230 to be assembled And the production can be simplified.

In addition, the conventional packaging machine of the existing company took the operation method of tightening the film by driving the rack and pinion driven by the motor to hold the film, which is an electrical system and a mechanical system for the motor power supply part and accurate transfer. While there is an advantage of taking the automatic transfer of the tray part from the consumer side, the basic components (vessel mounting sensor, motor, rack and pinion, etc.) have to enter a lot. There was a high risk of defects such as damage to the wires or loosening of the fasteners.

In addition, conventional manual packaging machines sometimes hold the film by using ferrite magnets (which are often used in door locks), which require strong noise and a certain amount of force when crushing or crushing each other. It is not reliable to apply to the film in such a way that it touches only the local area.

However, in the present invention, the use of force in the magnetic force as in the ferrite magnet, but in the same context, the area to hold by using the rubber magnet itself can be widened, and unlike the general rubber magnet N / S / N / S on one side Because the surface itself is specially manufactured as S poles instead of N poles, the shape used can be easily machined (cross rubber magnets need to precisely cut the N poles and S poles). Compared to the power of each other to maximize the power.

In addition, the rubber magnet plate can be manufactured at a lower price than the ferrite magnet, and since the magnet itself has rubber characteristics, there is no need for a separate frictional taping treatment to hold the film well on the surface of the rubber magnet plate. simple.

Although specific embodiments of the present invention have been described and illustrated above, it is obvious that the shape of the container seating port may be variously modified into a circle or the like according to the shape of the container rather than a rectangle. Such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, but should fall within the claims appended to the present invention.

Therefore, in the present invention, when the film is fused to the vessel, the configuration of the power transmission means for transmitting power to the heater is simplified, thereby making it easy to manufacture, disassemble and assemble, and thus lower the manufacturing cost. In addition, in the container seating part supporting the container in the tray, the actual molded rubber and the mold part (injection) supporting the rubber are separately manufactured to sandwich the compressed rubber member and the auxiliary rubber member, thereby simplifying assembly and production. There is an advantage to this.

In addition, the film transfer means for holding and transporting the film from the tray is made of a plurality of rubber magnetic plates, thereby increasing the area for holding the film itself, thereby increasing reliability, and unlike the general rubber magnet, Because it is specially manufactured with S pole, it can be easily processed. Since the magnet is a rubber plate, there is no need for separate frictional taping treatment on the magnet surface to hold the film. There is an advantage.
