2. Description of the Related Art For example, a cylindrical film insertion apparatus for inserting a cylindrical film such as a cap seal into a mouth portion of a bottle container or the like is disclosed in, for example, Japanese Utility Model Laid-Open No. 60-177001. There is something. As shown in FIG. 4, the tubular film fitting and inserting device 50 is accommodated in a long strip-shaped tubular film f to be supplied, and has an opening means 51 for opening the tip of the tubular film f; A cutting means 52 for cutting the cylindrical film f delivered in a state of being opened by the opening means 51 to a predetermined length below the opening means 51;
And the cutting means 5
2. A shaping means 53 for shaping a cap seal cs made of a cylindrical film f cut to a predetermined length into a substantially cylindrical shape for fitting into a mouth portion of the bottle container b, and a substantially cylindrical shape by the shaping means 53. Shaped cap seal cs
Is inserted into the mouth of the bottle container b.

The shaping means 53 is mounted so as to radially protrude from the rotation shaft 53b, and circulates while stopping at the delivery position α ₅₀ and the insertion position β ₅₀ with the rotation of the rotation shaft 53b. Openable mandrel 53a
Has a cap seal cs which is suitably opened by the opening means 51, in the delivery position alpha _50, is passed to the shaping means 53 by being inserted into the mandrel 53a which is stopped in the closed state, the cap by opening while the seal cs is fitted interpolated mandrel 53a moves in the fitting position beta _50, the cap seal cs is shaped in a substantially cylindrical shape.

[0005]

By the way, the inner diameter of a cylindrical film such as a cap seal formed of a shrink film is larger than the diameter (outer diameter) of a mouth portion of a container or the like in which the cylindrical film is to be mounted. Since the diameter is generally set, for example, as shown in FIGS. 5A and 5B, the container B conveyed to the film insertion position α
When the transport interval of the container B is narrow, the lower end of the cylindrical film F to be inserted into the opening of the container B is brought into contact with the upper end of the adjacent cylindrical film F already inserted into the opening of the container B. There is a problem that the cylindrical film F cannot be smoothly and reliably inserted into the mouth of the container B.

In particular, when the cylindrical film F to be inserted into the mouth portion of the container B is supplied in a state of being folded into a sheet, the cylindrical film F has a folding habit or the like. As shown in FIGS. 6 (a) and 6 (b), the tubular film F folded into a sheet shape cannot be opened in a completely cylindrical shape, and the fold portion is in a projected state. There is a possibility that the protruding fold portion may easily come into contact with the upper end portion of the adjacent tubular film F already inserted into the mouth portion of the container B.

For this reason, in the conventional film insertion device,
When containers are conveyed at narrow intervals, near the film insertion position, with the container conveyance interval temporarily widened by a screw conveyor, star wheel, etc., a cylindrical film such as a cap seal is It is designed to fit into the mouth.

However, when a plurality of containers are transported in a case in order to improve the self-standing stability of the containers during transportation, almost no space exists between adjacent containers accommodated in the case. Since no gap is formed, the space between the containers cannot be widened in such a case, and it is difficult to insert a cylindrical film such as a cap seal into the mouth of the container.

An object of the present invention is to provide a film capable of smoothly and surely inserting a tubular film into an inserted body even when the inserted body such as a container is conveyed at a narrow interval. An object of the present invention is to provide a fitting device.

[0010]

The film overlapped with each other in the conveying direction of the mandrel with respect to the adjacent film whose tip in the extrusion direction was extruded earlier. While maintaining state, the there is provided a film fitted apparatus characterized by being adapted to be fitted onto the fitting interposer.

[0011] In the film insertion device configured as described above, the film extruded from the mandrel by the film extruding means is such that the front end in the extruding direction of the mandrel is opposed to the adjacent film extruded first. While maintaining the state of overlapping each other in the transport direction,
Since the insertion interval between the inserted inserts conveyed to the film insertion position is narrow because the insertion insert is inserted into the inserted insert, even if the installation interval of the mandrel is narrowed accordingly, The end of the film extruded from the abutment does not come into contact with the end of the previously extruded adjacent film, and the film extruded from the mandrel is securely inserted into the target inserted body.

[0012] Further, as in the film insertion device according to the second aspect, the plurality of mandrels are provided with an endless chain which is hung over sprockets provided at a predetermined interval or at a predetermined interval. In a timing belt that is stretched over a pulley, the sprocket or the pulley is attached to the mandrel at an arc portion of the sprocket or the arc portion of the pulley. Even if the installation interval of the mandrel is narrowed in accordance with the inserted body conveyed by the above, in the arc part of the sprocket or pulley,
Since the interval between the tips of the adjacent mandrels is widened, the tubular film can be reliably inserted into the mandrel without being caught by the adjacent mandrel.
