  Hereinafter, an insertion operation of the tube-type article G into the cylindrical shrink film F will be described. First, as shown in FIG. 12A, after the preliminary opening means 42 (upper suction pad 42a) preliminarily opens the cylindrical shrink film F, a pair of left and right operations are performed as shown in FIG. When the pair of left and right movable guides 62 are closed by separating the member 70 the most, the fixed guide 61 and the movable guide 62 are inserted into the cylindrical shrink film F that is preliminarily opened as shown in FIG. Is done.

  Subsequently, as shown in FIG. 11 (b), by bringing the pair of left and right operation members 70 closer to each other and bringing the distal ends of the pair of left and right lower operation levers 66 closer to each other, Since the tip portions of the pair of left and right upper operation levers 64 are separated from each other, the movable guide 62 is also separated by the urging force of the coil spring 69, and as shown in FIG. The open end of F is widened in the left-right direction, and in this state, the article G is inserted into the cylindrical shrink film F from the front end side of the flat trunk portion.

  In the case of the tube-type article G, the barrel shape changes from the flat tip side toward the substantially circular cap side, so that the flat barrel tip of the article G is inserted into the cylindrical shrink film F. After that, as the amount of insertion increases, the cross-sectional shape of the cylindrical shrink film F approaches a circular shape, and a pair of left and right movable guides 62 as shown in FIGS. 11 (c) and 12 (d). Is pushed by the cylindrical shrink film F and the article G is inserted while approaching each other.

  As described above, in the opening / insertion unit equipped with such a spreading means 60, the pair of left and right movable guides 62 opens and closes according to the cross-sectional shape of the article G passing through the opening end of the cylindrical shrink film F. Even if the article G to be packaged is a tube container or the like whose cross-sectional shape changes greatly over the entire length, the opening end of the cylindrical shrink film F in the article G is The opening end of the cylindrical shrink film F can be expanded according to the shape of the passing part, and the article G can be smoothly inserted into the cylindrical shrink film F.

  In each of the above-described embodiments, the lower fixed guide 44a and the upper movable guide 44b, the fixed guide 61 and the movable guide 62 are always used from the start of insertion of the article G into the cylindrical shrink film F to the completion of insertion. Although inserted into the cylindrical shrink film F, the present invention is not limited to this. After the insertion end of the article G is inserted into the cylindrical shrink film F, the side fixed guide 44a and the upper movable guide 44b The fixed guide 61 and the movable guide 62 may be retracted outside the cylindrical shrink film F. In this way, after the insertion end of the article G is inserted into the cylindrical shrink film F, the side fixed guide 44a and the upper movable guide 44b, the fixed guide 61 and the movable guide 62 are retracted from the cylindrical shrink film F. In other words, the article G is a cylindrical shrink film while the tubular shrink film F itself is deformed along the article G even if it is a tube container or the like whose cross-sectional shape changes greatly over the entire length. It will be inserted in F and the article G can be smoothly inserted into the cylindrical shrink film F.

  Further, in each of the above-described embodiments, the packaging material MF that is fixed in a straight posture without tilting the cylindrical shrink film F with respect to the mount M is used. For example, the cylindrical shrink film with respect to the mount M is used.

By rotating the positioning guide 32 by the mechanism, the mount M may be set at the article insertion position in an inclined state. In addition, each positioning guide 32 is attached to the rotary table 31 so that the longitudinal direction of the cylindrical shrink film F faces the extrusion direction of the article G at the article insertion position δ, and the packaging material MF is attached. You may make it supply in the state inclined.

  In each of the above-described embodiments, the packaging material MF is intermittently supplied to the article supply position γ by the rotary table 31 and the packaging material MF is stopped, and the article G is inserted into the tubular shrink film F. However, the present invention is not limited to this. For example, while the article G and the packaging material MF are conveyed together while facing each other, the opening work of the cylindrical shrink film F and the cylindrical shape are performed. By performing the operation of inserting the article G into the shrink film F, it becomes possible to cope with high-speed operation. Specifically, the article supply unit, the packaging material / intermediate package conveyance unit, and the packaging material MF are conveyed together with the opening end of the cylindrical shrink film F and the insertion end of the article G facing each other. Are arranged opposite to each other, and an opening / insertion unit is mounted for each bucket of the bucket conveyor constituting the article supply unit. In this case, since the packaging material / intermediate package transport unit also serves as the intermediate package transport unit, there is no need to separately provide the intermediate package transport unit.

  Moreover, in each embodiment mentioned above, although the film packaging body PG with a mount is manufactured using the packaging material MF by which the cylindrical shrink film F was previously fixed to the mount M, for example, FIG. As shown in (g), after the article G is inserted into the cylindrical shrink film F without being fixed to the mount M, the intermediate package is fixed to the mount M and heated to form a cylindrical shape. The shrink film F may be heat shrunk, and as shown in FIGS. 14A to 14G, after the article G is inserted into the cylindrical shrink film F without being fixed to the mount M. The intermediate package may be heated first to form a film package in which the tubular shrink film F is thermally contracted, and the film package may be fixed to the mount M. In particular, when the latter manufacturing method is employed, the mounting posture of the film package with respect to the mount M can be arbitrarily set, so that an effect that the variations of the film package PG with mount that can be manufactured can be obtained. 13 and 14, reference symbol SP indicates a suction pad for preliminarily opening the cylindrical shrink film F, and reference symbol NF indicates a guide body for expanding the cylindrical shrink film F.

  Moreover, in each embodiment mentioned above, although the film packaging body PG with a mount is manufactured using the packaging material which consists of the mount M and the cylindrical shrink film F, it replaces with a cylindrical shrink film and a cylindrical stretch film Can also be used. In that case, for example, as shown in FIGS. 15 (a) to 15 (f), after the cylindrical stretch film S is attached to the article G without being fixed to the mount M, the film package is fixed to the mount M. do it. In addition, the code | symbol SP in FIG. 15 has shown the suction pad which preliminarily opens the cylindrical stretch film S, and the code | symbol NF has shown the guide body which expands the cylindrical stretch film S, respectively.
