Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for supplying a lid material in a filling packaging machine used for filling fluids such as beverages, pharmaceuticals, alcoholic beverages, gelled substances, and gas-containing liquids. It is.

(Prior art) Conventionally, as filling and packaging machines, Japanese Patent Application Laid-Open No. 142125/1983, Japanese Patent Publication No. 24243/1983, and Japanese Patent Publication No. 58-3
There are publications such as No. 9691.

In the method disclosed in JP-A-56-142125, after filling a container formed in a filling machine with contents, a portion of the container is temporarily sealed in order to supply a cover film as a lid material, and then the container is permanently sealed and the container is closed. It is a device that separates film covers one by one, and the remains of the film cover are wound up on a roll.

Japanese Patent Publication No. 61-24243 relates to a method for aligning patterns by detecting the position of a cover sheet, which is a lid material for sealing a container in a filling and packaging machine. A slit is provided in the section to stretch the film and align it with the container.

The device disclosed in Japanese Patent Publication No. 58-39691 detects a mark on the lid and aligns the seal position with the container when feeding the lid to the container in a packaging machine. A device for winding up the remains of the lid of the filling device, a device for sealing with the container, and a punching device are shown.

(Problem B that the invention seeks to solve) Aligning the position of the container in supplying the lid material is an important operation, but since the lid material is in the form of a thin film, it expands and contracts.

In particular, in aseptic filling machines and the like, a process such as applying a sterilizing agent to the lid material and then forcing it to dry with hot air is added, resulting in a state where the lid material is likely to expand and contract due to heating.

Furthermore, many filling machines are designed to wind up the remains of the lid material after the processes of the sealing device and the punching device, and this serves as a pulling force to pull out the lid material, making the lid material easily deformed.

Expansion and contraction in the longitudinal direction mainly occurs due to the force and heat applied to pull out the lid material. For this reason, the consistency between the printing position of the container and the lid material becomes poor, and a separate control is required to align the lid material.

Furthermore, since the containers of the prior art filling machine described above are made by molding synthetic resin sheets, it is necessary to control the positions between the containers to be constant.

Therefore, an object of the present invention is to provide a method for supplying a lidding material in a filling and packaging machine in which the lidding material does not expand or contract.

(Means for Solving the Problems) In order to achieve the above objects, the present invention provides the following method for supplying a lid material in a filling packaging machine.

That is, in a filling packaging method that seals a sheet-like lid material to a container, the sheet-like lid material is pulled out from a raw material roll by a feed roller, the sheet-like lid material is sterilized in the drawer, and then the container is filled with contents in a filling machine. A method for supplying lidding material in a filling and packaging machine characterized by cutting the lid material to a size larger than the mouth of the container either before or after welding and sealing it, or at the same time. This is a method for supplying a lid material in a filling and packaging machine, characterized by temporarily sealing the lid material with a part of the container when cutting to size, and then completely welding the lid material to the container.

In addition, in the above method, the container is cut to a size larger than the mouth of the container, and then the portion protruding from the lid material is cut or caulked stepwise inside or outside the filling and packaging machine, or inside and outside the filling and packaging machine. This is a method for supplying lidding material in a filling packaging machine characterized by the following.

(Function) The present invention uses a driving member such as a feed roller to pull out the lid from the roll, so that no tensile force is applied to the lid itself, and at the same time, the pulling force on the lid due to the operating force of the sealing device or punching device is reduced. In order to avoid this effect, cutting is performed either before or after welding and sealing the lid material to the container, or at the same time, without leaving any debris at a size larger than the container mouth.

(Example) The embodiments shown in the drawings will be described below.

First, a conventional filling and packaging machine will be explained.

Containers (3) fall one by one from the container supply section (8) onto the rails (2) (2) in the filling chamber (1), and the fallen containers are supported by the rails (2) (2) by their flanges. The chain (6) is driven by Sbrokent (4) and (5).
) is attached to the rail (2) (2
). Containers transported along the rails (2) (2) are housed in subchambers partitioned by front and rear pushing plates (7) (7), and are transported together with the subchambers.

During the transportation, the container is sterilized by the drug nozzle (9),
The drug is removed by heated air from the next heated air pipe (10).

The container (3) from which the drug was removed is connected to the sterile air supply pipe (11)
The chamber is filled with a filling nozzle (12) to which sterile air is supplied from, and the lid material is sealed with a sealing device (13).

The container with the lid sealed is secured to the rail (2) using the push rod (14).
) From (2), the container is pushed up and discharged.

In Fig. 2, (15) is the exhaust port, (16) is the first vacuum chamber, (17) and (1B) is the 2.3rd vacuum chamber.

The present invention relates to an improvement of a method for supplying a lid material in a filling packaging machine as described above.

The conventional method of supplying lid material as described above is to feed raw material rolls (19
) is pulled out from the lid material (a) and placed in the chemical tank (2).
After being immersed in a drying device (2) and coated with a disinfectant,
The lidding material sheet (a), which has been dried in step 1), sealed into a container by a sealing device (13), and has a lidding material punched out by a punching device (13''), is wound up by a winding roll (22). ing.

As described above, when the disinfectant is applied to the lid material and then the drying process is performed, the lid material expands and contracts by drying and heating the lid material.

In addition, the lid material is sealed using a sealing device (13) and a punching device (13').
After the process of ), the remains of the lid material are wound up with a take-up roll (22), which acts as a force for pulling out the lid material, and the lid material is easily deformed. Expansion and contraction in the longitudinal direction mainly occurs due to the force applied to pull out the lid material and heating. For this reason, the consistency between the printed position of the container (3) and the lid material becomes poor, and a control device is required to align the lid material.
It becomes necessary to control the position in between.

Therefore, the present invention is as follows.

That is, as shown in Fig. 1, the lid material (
a) is fed, pulled out by rollers (24) and (25), changed direction from the guide (27) and feed roller (26), and fed onto the container (3). Although not shown, sterilization is performed between the raw material roll (23) and the feed rollers (24) and (25) by a known method. The lid material (a) is the container (3
), the position detection device (28) detects this and the cutter (29) is activated to cut the lid material to a size larger than the mouth of the container (3). Next, the lid material cut by the sealing device (30) is sealed on the container, and then the rim portion of the lid material is punched out by a punching blade (trimming) (31). Note that, as shown in the figure, since the position detection device is provided in front of the sealing device, it is possible to improve the positional consistency with the container.

As described above, in the present invention, the lid material (a) is transferred to the raw material roll (23).
The pulling force is applied by the feed rollers (24) and (25) to prevent tensile force from being applied to the lid material itself and to reduce the influence of the tensile force on the lid material due to the operating force of the sealing device (30) and punching device (31). In order to avoid this, in the illustrated example, the lid material is cut to a size larger than the container shape before the sealing device (30). In addition to the method shown in the drawings, the cutting method may be performed after the sealing device (30) or may be performed simultaneously with the sealing device.

Further, although the illustrated device is described as a device that feeds containers one by one, it may be a filling machine that forms containers by forming sheets of synthetic resin material.

Furthermore, the remaining sills of the lid material punched out by the punching blade (31) are removed by suction using a suction device (not shown).

In addition, the position detection is performed by detecting a mark or pattern printed on the surface of the lid material, and the sealing device and the punching device may be integrated.

However, when cutting the lid material to a size larger than the mouth of the container, it is acceptable to temporarily seal the lid material with a part of the container and then completely weld it to the container, and cut it during the temporary sealing. It is.

As mentioned above, canting with a dimension larger than the container mouth is done either before or after the welding seal, or at the same time, but after that, the lid is closed in stages inside the filling packaging machine, outside the filling packaging machine, or inside and outside the filling packaging machine. Cut or caulk the part of the material that protrudes from the container.

In any case, the present invention uses a feed roller to pull out the lid material from the roll so that no tensile force is applied to the lid material, and also reduces the influence of the tensile force on the lid material due to the operating force of the sealing device or punching device. In order to avoid this, the lid material is cut to a size larger than the container shape individually or simultaneously with the welding seal before and after the sealing device.

(Effects of the Invention) According to the present invention, it is possible to eliminate the force applied to the lid material in the longitudinal direction due to the operation of the sealing device and punching device in the filling device when feeding the lid material, so the lid material does not expand or contract. .

In addition, even if the lid material is deformed, expanded or contracted due to thermal stress due to sterilization heating, etc., the position of the lid material should be adjusted just before the sealing device, and the cutting can be done either before or after the sealing device, or separately from the sealing device. By performing the welding and sealing simultaneously, the positional alignment between the lid material and the container can be improved.
