It is a perspective view. The automatic packaging machine 10 according to the present embodiment rewinds two roll-shaped packaging materials 11 wound in a roll shape and sends them in a developed state, and a hexahedron is provided between the two developed packaging materials 12 arranged vertically. In an automatic wrapping machine for sequentially wrapping a package-shaped article 13 in a predetermined direction in accordance with the delivery of the wrapping material 12 and heating and pressing the overlapping portions of the two wrapping wrapping materials to bond them together, A conveyor 14 for transferring the package, a heater part 15 for moving the package up and down along the front surface and the rear surface of the packaged article 13 so that the package material can be vertically moved in and out of contact with the expandable package material, and the package A cutter 16 that cuts at the center of the thermocompression-bonded portion of the material and a pressing member 23 that is arranged facing the heater member 15 and that has a relief groove 17 for the cutter are provided on both sides of the pressing member 23. The cutter 24 is provided with a rotatable roller 24. And a rotatable roller 21 on opposite sides of the member 15.

Here, as shown in FIG. 2, the heater member 15 is a drive mechanism for linearly driving the whole, for example, a geared motor 18, a pair of heaters 20, 20 supported by a main body via a spring 19, and The cutter 16 is arranged between the heaters 20 and 20, and the roller 21 is arranged outside the heater 20. The geared motor 18 is fixed to a frame (not shown) and includes a pinion gear 18a and a rack 18b. The roller 21 is rotatably supported by the main body of the heater member 15 and has an outer peripheral surface that is equal to the end surface of the heater 20. The cutter 16 is fixed to the body of the heater member, but since the heater 20 is supported via the spring 19 and the support bolt 22, the heater 20 is retracted when it comes into contact with the pressing member 23 arranged oppositely. Therefore, only the cutter 16 projects and cuts the packaging material 12. The conveyor 14 is continuously or intermittently driven by a control mechanism outside the drawing.

The pressing member 23 has an escape groove 17 for the cutter 16 formed at its tip, and rollers 24, 24 are rotatably arranged on both sides of the pressing member. The outer peripheral surface of the roller 24 is arranged in the same manner as the end surface of the pressing member 23. The entire pressing member 23 is linearly supported by the geared motor 29. Here, the geared motor 29 is fixed to a frame (not shown) and driven by a rack 29b meshed with the pinion gear 29a. Further, in the vicinity of the heater member and the pressing member 23, guide rods 30a and 30b for guiding the expanded packaging material are arranged to guide the packaging material.

The operation of the automatic packaging machine configured as described above will be described. First, the article to be packaged 13 is conveyed while being vertically held by the conveyor 14. The article to be packaged 13 is transferred while abutting on the fusion-bonded portions 12a of the upper and lower expanded packaging materials 12, 12. At this time, the heater member 15 and the pressing member 23 are separated from each other. Next, when the packaging material 12 has passed the rear end of the article to be packaged 13, the conveyor 14 is stopped. When the conveyor stops, the heater member 15 and the pressing member 23 come into contact with each other from above and below while being driven by the geared motors 18 and 29. The heater 20 of the heater member 15 is heated by energization. Therefore, the packaging material 12 can be fused by pressing the packaging material 12 with the pressing member 23. Since the rollers 21 and 24 that are rotatably supported are disposed before and after the heater member 15 and the pressing member 23, the packaging material 12 does not bend or wrinkle. In other words, the roller handles the packaging material without difficulty, so it does not bend.

The article 13 to be packaged in a tubular shape is further transferred by the conveyor 14 and stopped at the folding section B 1. In the folding part B, the tubular packaging material remaining on both sides is folded by the fixed protection strip 25 and the folding member 26. Next, the article to be packaged 13 transferred to the finish folding section C by the conveyor 14 is folded from above and below by the finish folding member 27. The end of the folded packaging material 12 is heat-melted and fixed by the finish thermocompression bonding portion 28. FIG. 3 shows a packaged object packaged by the automatic packaging machine of the present invention.
