Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sterile winding roll used as a material for packaging containers, etc., and a method for manufacturing the same.

BACKGROUND ART Conventionally, there are an in-line method and an off-line method for filling a container formed of a packaging material with a spiritual substance such as juice in a sterile state.

The in-line method incorporates a packaging material sterilizer inside the filling machine, which complicates the structure of the filling machine and makes the equipment larger and more expensive. On the other hand, the off-line method supplies sterile packaging materials to a filling machine, and there is no need to provide a packaging material sterilizer, which has the advantage of being cheaper and requiring simpler equipment.

However, in the offline method, the packaging material is sterilized outside and then transported into the filling machine. 2 at the time of injection
There is a risk of contamination.

For this reason, as shown in FIG. 1, a sterilized sheet-like packaging material 2 is wound around a rod-shaped core material 1, and this is packed in a bag 8 to prevent contamination from the outside.

Incidentally, even when five people put the sheet-like packaging material 2 packed into the bag 8 into the filling machine, the outer surface of the bag 3 was exposed to the outside air, so it was not in a sterile state. Therefore, filling machines are generally provided with a sterilization chamber, and the bags 8 are sterilized in this sterilization chamber. However, many wrinkles 4 are formed in the bag 8, and it is difficult to completely sterilize the bag by partially folding the inside of the wrinkles 4.

On the other hand, in order to eliminate the above-mentioned wrinkles, it is possible to use a shrink film, but since shrink film packaging requires holes for air venting, it is not possible to maintain a sterile state.

The present invention was made in order to improve the above-mentioned problems with the conventional offline filling machine, and it eliminates the occurrence of wrinkles in the outer packaging material wound around the outside of the sheet-like packaging material. An object of the present invention is to provide a sterile winding roll that can be completely and evenly sterilized in a sterilization room, thereby preventing secondary contamination, and a method for manufacturing the same.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing a schematic structure of a manufacturing device for a sterile winding roll according to the present invention. is provided with an electron beam (KB) generator 13, and a scanning unit 14 connected to this FiB generator 13 faces into the sterilization chamber 11.The open sterile chamber 12 is connected to a supply source of sterile air (not shown), and the inside The holding part 1 of the core material 16 winds up the sterilized sheet-like packaging material 15.
7. A holding portion 20 of 9 is provided, and a glove 2J for manual operation from the outside is attached. A sterile take-up roll take-out part 22 is provided on one side of the sterile 1000 gimbal 12, and this take-out part 22
Half of the sterilization tank 23 is facing inside. In addition, a large number of guide rollers 24...24 are arranged in the sterilization chamber II and the sterilization chamber 12, and the sheet-like packaging material 1 before sterilization is
Sheet-like packaging material pulled out from the roller 25 wound around 5
We are guiding you through the journey of 5.

In addition to the above-mentioned FB sterilization, it is also possible to perform γ-ray sterilization or EOG (ethylene oxide gas) sterilization, but both have slow processing speeds, and R-ray sterilization requires radiation MS shielding. requires huge equipment. however,
EB sterilization has the advantage that the equipment itself does not need to be turned into a pilot type, and that the packaging material can be sterilized while being continuously fed at a high speed.

On the other hand, the window cleaner 19 for winding up the exterior packaging material 18 set in the sterile chamber 12 has a rod shape as shown in FIG.
In addition, as shown in FIG. 4, the outer packaging material 18 has a width that can cover the flange (described later) of the core material 16 for sheet-like packaging material, and its - side, that is, the surface that wraps around the sheet-like packaging material 15. A double-sided adhesive tape 26 is attached to both sides of the tape, and a double-sided adhesive tape 27 is attached to the width direction as well. The IMJ spacing of the double-sided adhesive tapes 27 and 27 is made larger than the outer circumferential length of the flange of the core material 16.

As shown in FIG. 5, the core material 16 for winding up the sheet-like packaging material 15 has flanges 29 at both ends of a pipe-like shaft portion 28.
29, this flange device, an outer peripheral portion 29a of 29,
The width of 29a is approximately equal to the width of the double-sided adhesive tape 26.

Next, a method for producing a sterile winding roll will be described below.

First, the core material 19 for the outer packaging material 18 is immersed in the sterilization tank 23 filled with H202 liquid or sterilized by spraying with H2O2, and then attached to the holding part 17 in the sterile chamber 12.

On the other hand, the outer packaging material 18 before sterilization and the sheet-like packaging material 15 are continuously wound around the a-ru 25, and the order is such that the outer packaging material 18 is pulled out first.

Then, the exterior packaging material 18 is pulled out from the roll 25 and is run inside the sterilization chamber 11, while the exterior packaging material 18 and the double-sided adhesive tapes 26 and 27 attached to this packaging material 18 are sterilized. Then, the sterilized outer packaging material j8 is carried into the sterile chamber 12, and the outer packaging material 18 is wound around the core material]9 that was previously attached to the holding part 17.

Too bad, the rear end of the exterior packaging material 18 has a sheet-like packaging material 15.
The sheet-like packaging material 15 that is continuous with the outer packaging material I8 passes through the sterilization chamber 11, is sterilized, and enters the sterile chamber 12.

Once the sheet-like packaging material 15 is placed in the sterile chamber 12, the adhesive tape or welded adhesive portion between the sheet-like packaging material 15 and the exterior packaging material 18 is cut using a trap cutter through the glove 21. Following this operation, the core material 19 around which the exterior packaging material L8 has been wound is transferred to the holding section 20.

After this, the core material I6 for the sheet-like packaging material 15 is sterilized in the sterilization tank 23, attached to the holding part 17, and the tip of the sheet-like packaging material j5 facing the inside of the sterile chamber 12 is attached to the core material 16 with double-sided adhesive tape. Or fasten with thermal adhesive. After this, the core material 16
The sheet-like packaging material 15 is wound up until the diameter of the winding I) and the diameter of the flange 29 become equal to each other, the state shown in FIG. 6 is obtained, and the sheet is cut with a cutter.

Next, the outer packaging material 18 that was previously rolled up is placed on the sterile operating gloves 2.
While peeling off the release paper of the double-sided adhesive tape 26 on both sides, remove the outer peripheral part 29 a of the flange 29 of the core material 16 from the I/C.
Wrap and glue. (- After winding up the tool, use a cutter to cut the double-sided adhesive tape 27 in the width direction, leaving a sufficient adhesive margin, and use the outer packaging material 18σ)
The reason why I cut the double-sided adhesive tape 27 leaving a sufficient margin to make it possible to cut the double-sided adhesive tape 27 with -18 pressure 1 material 1 Q small Yo Shiba + y → A was to prevent groaning during sterilization in the filling machine. This is done by preventing excess packaging material from coming out from the adhesive tape 27 to prevent poor sterilization.

On the other hand, since the outer periphery of the flange 29 and the outer periphery of the sheet-like packaging material 15 are bonded to the road surface, the double-sided adhesive tapes 26 and 27 will adhere sufficiently to the ends of the exterior packaging material 18. The sterile winding roll 30 obtained in this way was
Shown in the figure.

FIG. 8 and FIG. 9 show another embodiment, and in this embodiment, i-J: As shown in FIG.
8 is a sheet-like packaging material made by laminating a plastic film 31 having thermal adhesive properties and a plastic film 32 not having thermal adhesive properties, and wrapping such an exterior packaging material 18 around a core material I6. A method of winding the wire around the outside of the wire 15 will be explained with reference to FIGS. 9(a) to (d). Note that the work done before this is the same as above.

First, as shown in Fig. 9 (ra), leave a sealing margin 18ai of a certain width from the tip of the outer packaging material 18, and seal it with a roller type.
9qθ) ノ
The exterior packaging material 18 is supplied, the core material 16 is rotated, and the exterior packaging material 18 is thermally bonded (welded) to the flange outer peripheral portion 29a.

Then, as shown in FIG. 9(b), at the point where the -peripheral bonding is completed, remove the sealer 33 and seal with other sealers 34 and 34 as shown in FIG. 9(c).+8a, 18b
Paste the inside surface of the paper. At this time, the sealer 34.
34 straddles the exterior hue.

Next, as shown in gll(a), the gassho paste part 35
is cut in the width direction, and the roller-type sealer 33 is used again to press near the base of the gassho sticking part 35 to ensure sealing.

In this way, since the surface of the gassho sticking part 35 is coated with the blank film 32 or C-, fx which does not have thermal adhesive properties, the gassho sticking part 35 always maintains an upright state.
This means that there are no locations where sterilization failure occurs.

As explained above, according to the present invention, as a blank winding roll used in an off-line filling machine, the packaging material has no wrinkles and is sterilized when it is put into the filling machine for the first time. Sterilization can be carried out evenly and reliably, the problem of secondary contamination can be completely eliminated, and the method for producing such aseptic winding rolls has many effects such as efficient production without waste.
