Also, arack gear 19 is attached to the bottom of theguide rail 15, and is coupled to apinion 21 provided inside theouter casing 1 so that thefood container 3 loaded on thejig panel 13 may be loaded into and pulled out of the machine while theguide rail 15 is moved back and forth according to driving of the motor. - In addition, a
container support plate 22 for supporting the lower part of thefood container 3 seated is provided at a position on the lower side of the container receiving hole 11 of the jig panel. Accordingly, thefood container 3 seated is configured to be moved up and down while thecontainer support plate 22 is moving up and down automatically when thetray 5 is moved back and forth by the operation of a ball screw rotating by the driving of the motor. Since the operation of moving up and down of thecontainer support plate 22 is the same as in the conventional art, a detailed description thereof will be omitted. - Also, the upper and lower parts of the
tray 5 are provided with fourbearings 23 fixed to the inner wall surface of theouter casing 1 in front, rear, left and right, respectively. In thebearings 23, a heater unitdriving support shaft 25 with the bearing is inserted in a spring-tight state by acompression spring 26. The left and right heater unit drivingportion support plates 27 are connected to the lower end of the heater unitdriving support shaft 25 in the front and rear directions, respectively, and a roller bearing 29 is attached to the middle part thereof. - In addition, a heater unit driving portion 9 is configured such that an
eccentric cam 31 is provided in contact with the upper part of the roller bearing 29, and is connected by a chain or gear to themotor 35 fixed to thelower frame 33 of theouter casing 1. - In addition, the left and right heater
unit support plates 36 are provided at the upper end portion of the heater unitdriving support shaft 25 in the front and rear directions, and aheater unit 7 of known manner is disposed between the left and right heaterunit support plates 36. Theheater unit 7 is configured to seal the opening of thefood container 3 by heating and cutting the supplied film while being moved up and down by the operation of theeccentric cam 31 mounted on the heater unit driving portion 9. - The
unexplained reference numeral 38 is a limit switch. - In the seal-packaging machine for a food container of the present invention configured as described above, when seal-packaging the opening of the food-carrying
container 3 with a film, first, a switch for pulling out the tray is turned on and thepinion 21 connected to the motor is rotated, and then therack gear 19 and the ""-shaped guide rail 15 coupled thereto are engaged with the ""-shaped guide 17 and moved forward, thereby allowing thetray 5 mounted on thejig panel 13 to be pulled out to the outside. - When the switch for pulling out the tray is turned on again after the
food container 3 containing food is loaded on thecontainer support plate 22 inside the container receiving hole 11 of thetray 5 pulled out as described above, thepinion 21 connected to the motor rotates in the opposite direction. Then, therack gear 19 coupled to the pinion and the ""-shaped guide rail 15 engage with the ""-shaped guide 17 move reliably backward without swaying left and right. Therefore, as shown inFIG. 3 , thetray 5 and thefood container 3 loaded thereon are properly seated in the correct position inside the machine. - As the
tray 5 enters in this way, an operation of lowering thecontainer support plate 22 is linked at the same time, so that thefood container 3 loaded on thecontainer support plate 22 is fully seated in the container receiving hole 11, and the entry of thetray 5 is completed simultaneously. - When the
food container 3 is seated in an designated position in this way, themotor 35 fixedly provided on thebottom frame 33 of the lower side of thetray 5 is operated to rotate theeccentric cam 31 of the heater unit driving portion 9, and the roller bearing 29 which is provided in contact with the lower side of theeccentric cam 31 rotates.

At the same time, theheater unit 7 provided between the left and right heaterunit support plates 36 at the upper end of the heater unitdriving support shaft 25 is lowered as shown inFIG. 4 . Accordingly, a sealing operation is performed wherein the heated heater of theheater unit 7 heat-bonds and cuts the entire opening of thefood container 3 seated in the container receiving hole 11 of thetray 5 evenly with a film, and thus thefood container 3 will be sealed. - Accordingly, by the hot heater of the
heater unit 7, a sealing operation for thermosetting evenly with a film the entire opening of thefood container 3 seated in the container receiving hole 11 of thetray 5 and cutting the finished film is performed, and thus thefood container 3 will be sealed. - When the seal-packaging operation of the food container is completed by this process, the
eccentric cam 31 rotates continuously to raise the roller bearing 29 which contacts theeccentric cam 31. By this upward movement, theheater unit 7 is moved upward and returned to its original position by the elastic force of the compression spring 37 attached to the lower end portion of the heater unitdriving support shaft 25. Then, the motor drives to move thepinion 21 of thetray 5 on which thefood container 3 to be seal-packaged is loaded. Subsequently, therack gear 19, theguide rail 15, and thejig panel 13 attached thereto are pulled forward, and the sealedpackaging food container 3 loaded on thetray 5 is pulled out of the machine, and thus the seal-packaging operation is completed. - Therefore, according to the seal-packaging machine for a food container of the present invention, in a horizontal state along four heater unit
driving support shafts 25 provided on the four sides, theheater unit 7 for sealing the film may be uniformly operated up and down according to the operation of theeccentric cam 31 of the heater unit driving portion 9.
