The container body 7 adsorbed by the adsorbing portion 74 is delivered to the opener 65 by the rotation of the rotary table 75.

  This embodiment has the above-described configuration, and an example of its use will be described next. First, the material reel 6 fed by the feeding device 70 is cut at a predetermined position by a cutter 71, and when the container body 7 is formed, it is forcibly dropped by the feeding means 79, and the generated scrap 73 is shooter Discarded via 80. As shown in FIG. 7 (a), the original reel 6 has a film that is gusset-folded on both sides so as to have a bag shape in advance, and the dot portion 6a is sealed to form a cylinder. Therefore, by cutting the virtual portion 6b, it is possible to simultaneously form the container body 7 and the scrap 73 for forming the bottom of the next container body 7 as shown in FIG.

  Next, when the container main body 7 falls to a predetermined position, the rotating suction unit 74 of the container main body supply device 72 sucks and holds the container main body 7 (position a shown in FIG. 3) and further rotates in synchronism. It is clamped and delivered to the opener 65 at the lowered position 64 (see the position b in FIG. 8 and FIG. 8).

  On the other hand, in the spout supply section 1, the spouts 3 are transported in a line, and each spout 3 is sequentially delivered to the rotating clamp body 16 of the spout supply device 15 (position c shown in FIG. 3). ). Further, the spout 3 held by the clamp body 16 is rotationally transferred and is sandwiched by the spout clamp 29 that rotates the container forming section 10 as shown in FIG. 6 (b) (position d shown in FIG. 3).

  When the spout 3 is held by the spout clamp portion 29 and the container main body 7 is held by the opener 65, the spout 3 and the container main body 7 are turned into FIG. 3 by the rotation of the upper rotary table 19 and the lower rotary table 20. When rotating to the position indicated by e, the opener 65 raises the container body 7 to the heating position A while opening the upper edge of the container body 7 by the respective cam mechanisms (see FIG. 9 (a)), and the container body 7, the lower side of the spout 3 held by the spout clamp 29 is inserted to a predetermined position.

  Next, the cylinder 50 of the heater means 36 of the sealing device 35 is operated to retreat the rod 50a, so that the levers 42a and 42b are swung by the link mechanism and heated by the heater 43 and in the expanded state. The members 45a and 45b are closed, and the upper edge portion of the container body 7 and the seal portion 3a of the spout 3 are pressure-bonded with a predetermined pressure. At this time, the other heating member 45b is slightly swingable (a state in which rattling has occurred), so that the seal portion 3a of the spout 3 enters the recess 47 of both the heating members 45a and 45b, It becomes possible to make it contact | adhere reliably over the whole upper edge of the container main body 7. FIG.

  Further, after the container body 7 and the spout 3 are integrally pressure-bonded and sealed, the rod 50a of the cylinder 50 advances to swing the levers 42a and 42b, so that the heating members 45a and 45b are separated. In addition, this heating process is performed while the container main body 7 and the spout 3 move to the position of f shown in FIG.

  When the opener 65 releases the suction of the container body 7 and the clamp part 29 is raised, the spout 3 sandwiched by the clamp part 29 is of course integrated with the container body 7 sealed by the spout 3. The temperature rises to the cooling position B (see FIG. 9B). In the cooling position B, the cylinder 50 swings the levers 52a and 52b in the same manner as described above, so that the cooling members 56a and 56b of the cooler means 37 approach each other, and the seal portions of the container body 7 and the spout 3 are pressed and cooled. To do.

  In this cooling step, the container main body 7 and the sealing portion of the spout 3 are fitted in the recesses 47 of the cooling members 56a and 56b as in the heating step, so that the cooling can be reliably performed as a whole. Further, the heating step and the cooling step are preferably performed by repeating the pressure bonding 2-3 times or by changing the strength of the pressure bonding force several times, so that the sealing can be made more reliable. In addition, this cooling process is performed while the container main body 7 and the spout 3 move to the position of f from g shown in FIG.

  Further, as shown in FIG. 10, the container 13 in which the spout 3 is integrally attached to the container body 7 is transferred to a clamp part (not shown) that rotates in synchronization with the discharge part 12 (see h in FIG. 3). Position) and discharged by a discharge conveyor.

  The above-described container manufacturing process continuously performs heating and cooling operations for heat welding between the container body 7 and the spout 3 while moving the container body 7 and the spout 3, thereby improving work efficiency. Therefore, a series of container manufacturing processes can be performed automatically and at high speed.

  In addition, since the cylinder 50 and the levers 42a, 42b, 52a, 52b in the heater means 36 and the cooler means 37 are connected via the link member, the heating members 45a, 45b can be used even with the small cylinder 50. In addition, the pressure-bonding force of the cooling members 56a and 56b can be increased, and as a result, there is an advantage that the entire sealing device can be reduced in size.

  The present invention is not limited to the above embodiment. For example, in the above embodiment, the heater means 36 and the cooler means 37 are arranged in the vertical direction. It is also possible to do.
