The present invention relates to a fitting device and an inner guide unit for improving the opening of a tubular film after cutting, which is mounted on the film fitting device.

  This type of film covering apparatus is fed by a long film sending unit that pulls out a long film from a raw roll (not shown) mounted on the raw material feeding apparatus, and the long film sending unit. By cutting a long film coming into a predetermined length, a film cutting unit that forms an individual cylindrical film, and a cylindrical film separated from the long film by this film cutting unit is put into a predetermined state A mandrel that opens to the mandrel, a film transport unit that transports the tubular film fitted to the mandrel to the lower end side of the mandrel, and the tubular film that is transported to the lower end of the mandrel by the film transport unit by a delivery roller. Placed between the mandrel and the film fitting position directly under the mandrel at a specified timing In such a film fitting apparatus, after the end of the cut long film is fitted on the mandrel, the cylindrical film having a predetermined length is cut off. Since the cut end of the long film is in a pseudo-adhesive state and is difficult to open, the pseudo-adhesion of the cut end of such a long film can be securely attached to the mandrel. An inner guide for releasing the state is installed on the upstream side in the feeding direction of the long film in the film cutting unit.

  As shown in FIG. 10, the inner guide unit 90 supports an inner guide 91 accommodated in a strip-shaped long film LF folded in a sheet shape, and supports the inner guide 91 from the outside of the long film LF. An inner guide 91 that is composed of a guide support 97 and is housed in the long film LF forcibly separates the vicinity of the cut end of the strip-shaped long film LF folded into a sheet shape, The pseudo adhesion state of the cut end of the length film LF is released.

  As shown in the figure, the inner guide 91 includes a pair of flat base members 92 and 92 that are connected to each other via a connecting member 94, and a part of the peripheral surface of each of the outer edges of the base members 92 and 92.

  By the way, when the inner guide unit 90 as described above is mounted on the film fitting device, the urging force of the spring plate 96 of the inner guide 91 can release the pseudo-adhered state of the cut end of the long film LF, and the cutting The end portions of the long film can be smoothly and surely fitted to the mandrel, but the upstream support rollers 98U and 98U of the guide support 97 and the downstream support rollers 98D and 98D are provided on the upstream side of the inner guide 91. Since the folds on both side edges of the long film LF are not positively pressed against the guide rollers 93U, 93U and the downstream guide rollers 93D, 93D, the long film LF folded into a sheet shape It was not possible to relieve the crease of the tube, and the tubular film opened by the mandrel was delivered from the mandrel On the other hand, because the tubular film tries to return to a flat state by the springback action of the crease portion, the tight tubular film whose diameter is set slightly larger than the outer diameter of the fitted body is smooth and reliable. There is a problem that it cannot be fitted to the fitted body. In particular, when a tubular film is fitted to a fitting body having protrusions extending radially outward on the outer peripheral surface, such as when a cap seal made of a tubular film is fitted to a cap portion with a hinge In addition, the problem will appear prominently.

  Further, the upstream support rollers 98U and 98U and the downstream support rollers 98D and 98D of the guide support 97 are positively pressed against the upstream guide rollers 93U and 93U and the downstream guide rollers 93D and 93D of the inner guide 91. Although it is conceivable that the folds of the long film LF are spread and the folds of the long film LF are removed, in this case, the degree of freedom of the inner guide 91 with respect to the guide support 97 is lost, and the upstream side support roller 98U. , 98U and the downstream support rollers 98D and 98D are clogged, and the long film LF cannot be smoothly and reliably delivered.

It can be positioned in the front-rear direction.

  As shown in FIG. 8, the support-side pressing rollers 81A and 81B sandwich the folds on both side edges of the long film LF between the guide-side pressing rollers 65 and 65, respectively. By pressing the support-side pressing roller 81A against the one guide-side pressing roller 65 by the urging force, the other guide-side pressing roller 65 is pressed by the support-side pressing roller 81B, and the folds at both side edges of the long film LF The part is designed to be expanded. When the support side pressing rollers 81A and 81B sandwich the fold portion of the long film LF between the guide side pressing rollers 65 and 65, respectively, a pressing force of 1.8 kgf or more is applied to the long film LF. It has become.

  As described above, the support rollers 77A and 77B support the inner guide 61 with a play that is slightly movable in the vertical direction, and the circumferential surface of the groove is the upstream guide of the inner guide 61. The rollers 64U and 64U are not positively pressed against the overhanging portions of the rollers 64U and 64U. The support rollers 77A and 77B are pressed against the total weight (for example, 0.28 kgf) of the inner guide 61 via the upstream guide rollers 64U and 64U. ) (1/2) (0.14 kgf) is added, so that the fold portion of the long film LF cannot be completely spread as shown in FIG.

Can be fitted.

  Further, since the inner guide unit 60 presses the one support side pressing roller 81A against the one guide side pressing roller 65 by the biasing force of the spring plate 80A, both the support side pressing rollers are completely fixed. Unlike the case of pressing in the state, the inner guide 61 can move slightly in the width direction of the long film LF. Therefore, the long film LF is less likely to be clogged at the places pressed by the support side pressing rollers 81A and 81B, and the inner guide 61 can be smoothly and reliably passed while removing the folds of the long film LF.

  Further, in this film fitting apparatus 1, the driving roller 11 and the driven roller 12 of the long film delivery unit 10 disposed on both sides of the connecting plate 68 of the inner guide 61 are pressed by the support side pressing rollers 81A and 81B. Since the folds on both side edges of the unfolded long film LF are not sandwiched, the folds of the long film LF once relaxed are creased again by the driving roller 11 and the driven roller 12. It will never be done.

  Further, since the inner guide unit 60 supports the inner guide 61 by the pair of support rollers 77A and 77B constituting the guide support 70, the pair of upstream support rollers and the pair of downstream support rollers. Compared to the conventional inner guide unit that supports the inner guide, the portion supporting the inner guide 61 becomes shorter, and guide side pressing rollers 65 and 65 for relaxing the folding of the long film LF Even if the support-side pressing rollers 81A and 81B are provided, the entire length of the inner guide unit 60 is not increased, and a substantially similar installation space as that of the conventional inner guide unit may be secured.

  In the above-described embodiment, the pair of guide-side pressing rollers 65 and 65 and the pair of support-side pressing rollers 81A and 81B are provided. However, the present invention is not limited to this, and for example, feeding a long film LF A plurality of pairs of guide-side pressing rollers and a plurality of pairs of support-side pressing rollers may be disposed in the direction, and the long film LF may be folded in stages.

  In the embodiment described above, the inner guide unit 60 is provided with the guide-side pressing rollers 65 and 65 and the support-side pressing rollers 81A and 81B for relaxing the folding of the long film LF. With a film-fitting device that separates the tubular film from the long film, or a film-fitting device that separates the tubular film by breaking the perforated long film at the perforated part Since the long film is cut or broken on the mandrel and it is not necessary to provide the inner guide unit itself, in the case of such a type of film fitting apparatus, the guide side pressing roller 65 is provided on the mandrel portion. , 65 and support side pressing rollers 81A, 81B are provided, and these rollers are provided. Thus by pushing on the mandrel sandwich the folded portion of the long film LF, it may be relaxed folding habit of long film LF.

  In the above-described embodiment, the film fitting device for fitting the tubular film F to the neck portion of the bottle container B has been described. However, the inner guide unit of the present invention is limited to such a film fitting device. Needless to say, the present invention can be applied when various tubular films are fitted to various fittings other than containers.
