Description

Technical field

The invention relates to a machine for filling and packaging, transversely sealing and cutting pipes of the packaging material and filling each container with liquid food product.

State of the art

In the manufacture of packaging containers filled with a liquid food product, for example milk, mineral water, tea, juice, soup, alcohol, a web of laminated packaging material is used. A packaging container is formed by sealing the packaging material by heat sealing, ultrasonic welding, and the like. For example, in a filling and packaging machine, the edges of the laminated packaging material are joined together, wherein the laminated packaging material takes the form of a pipe. The lateral edges of the packaging material overlap each other so as to form an overlap. This overlap is pressed by a strip covering the cut surface of the inner edge of the longitudinal seam, and the overlap is heat sealed by means of a corresponding device in the longitudinal direction. In the transverse direction, the laminated packaging material is sealed with a transverse sealing device, when the tube of the laminated packaging material is filled with liquid food product, after which the packaging material is cut to form a semi-finished product in the form of a pillow-shaped container. After giving this capacity a given shape, a finished package is obtained.

In FIG. 7 is a schematic perspective view of an exemplary filling and packaging machine. The bobbin-like and web-shaped laminated packaging material 1 is loaded into a filling and packaging machine. Laminated packaging material 1 contains a flexible laminate laminating a paper substrate and layers of polyethylene resin on both sides of the paper base. If necessary, between the paper substrate and the film layer is a barrier layer comprising aluminum foil, a gas-tight layer and the like. The decorative elements are printed in areas corresponding to the surface of the packaging container 14.

The unwound layered packaging material 1 is continuously fed by a conveyor feeder and transported to the tape applicator 3 through bending rollers and damping rollers. Tape 2 is continuously applied to one of the edges of the laminate packaging material 1 of the tape applicator 3.

If necessary, a tear-off tab is attached to the laminate packaging material 1 using a tear-off tongue applicator. Laminated packaging material 1 enters the sterilizing tank 4 and is sterilized in the sterilizing tank 4 using a sterilizing liquid - hydrogen peroxide and the like. Laminated packaging material 1 is fed to an air scraper 5 for drying with an air scraper 5. Laminated packaging material 1 enters the aseptic chamber 40 to ensure that the tube-shaped packaging material is filled with liquid food in an aseptic atmosphere. Using molding rings 6 and other molding rings, the laminate packaging material 1 gradually acquires a tube-like shape.

The tube-like laminated packaging material 1 is preheated with hot air from a pre-heater 8 of the longitudinal sealing device to perform longitudinal sealing. The liquid food product is poured into a tube-shaped layered packaging material 1 from the lower end of the pipe nozzle 7.

An example of filling a tube-like packaging material from a filling tube with a liquid food product to a predetermined liquid level is shown in FIG. 8.

The vertical section of the filling tube 7 is inserted into the inner lower part of the tube-like packaging material 1. The portion located earlier in the direction (“above”) is connected to the control valve 32. A cylindrical float 34 is located at the periphery of the vertical section of the filling tube 7. Floating in the liquid food product and located between the tube-shaped packaging material 1 and the filling tube 7, the float 34 is placed around the outer surface of the vertical section of the filling tube 7 with the possibility of free movement up down. A detectable means 35 (magnet, transmitter, tongues, etc.) is mounted on the float 11. A detector 31 is located on the outside of the tube 1. The detector 31 converts the change in signal intensity from the detected means into an electric current, which the detector generates as an electric signal. Upon reaching a level above a predetermined level, the detector gives a stop signal, and at a level below a predetermined level, it accordingly provides an enable signal to the control means 33. In the area earlier along the filling tube 7, a flow control valve 32 is installed, controlled by the control means 33.

The fluid level is coordinated relative to a given level.

The tube-like laminated packaging material 1 is directed downward and fed to the transverse sealing device 10, as shown in FIG. 7. The tube-like laminated packaging material 1 is heat-welded by a press in the transverse direction and takes the form of a container. The laterally sealed laminate packaging material is cut with a cutter and a pillow-like pre-container 13 is formed.

A detailed partial sectional view of the transverse sealing device 10 is shown in FIG. 9. In this embodiment, the food-filled tube-like packaging material 1 is first held by an upper pair of sealing clips 10a and counter-clamps 11. When the tube-shaped packaging material 1 is fed down to a distance corresponding to the length of one packaging container, it is held by a pair of upper forming flaps 41 and 41 and takes an approximate shape of the container. Transverse sealing forms two transverse sealing zones. The middle of the sealing zones of the connected pillow-shaped preformed containers is cut by the cutter 42, and thus, the pillow-shaped preformed containers 13 are formed.

In the embodiment with high-speed transverse sealing, pre-molding and cutting, two pairs of sealing clamps and counter-clamps, as well as forming shields, are provided, the first pair having completed the transverse sealing, pre-forming and cutting steps is sideways and returns to the top, and the next steps of transverse sealing, pre-molding and cutting are repeated.

The preliminary container 13 is transported and takes its final shape using the final molding device 15, as shown in FIG. 7 and, thus, a packaging container 14 is formed filled with a liquid food product.

SUMMARY OF THE INVENTION

Objectives of the invention

In the aforementioned filling and packaging system, the pressure of the liquid food product filling the tube is a positive pressure corresponding to the depth of the liquid from the liquid level. When forming packaging material with the help of forming shields, the positive pressure of the liquid food product in the tube interacts with the external pressure of the forming shields in order to qualitatively form the packaging material.

In addition, such positive pressure also maintains the filled food product in good hygiene conditions. That is, even if the packaging material has small cracks, cracking and pinholes, the liquid food product only leaks from such points to the outside, but no external atmospheric substances enter the pipe and do not pollute the liquid food product in the pipe.

The objective of the invention is to provide a machine for filling and packaging, capable of easily pre-forming using molding shields by maintaining a positive pressure of the liquid food product in the pipe, capable of preventing the pressure of the liquid food product from falling to a negative pressure value, even if the pressure of the liquid food product decreases for changes in the pressure of a liquid food product, and capable of preventing the ingress of external atmospheric materials into the pipe.

The solution of tasks

According to the invention, in a filling and packaging machine, the web-shaped packaging material is continuously fed and takes the form of a pipe, wherein the pipe with overlapping overlapping of both ends of the packaging material is sealed longitudinally in the longitudinal direction, the liquid food product from the filling tube is poured to a predetermined liquid level in a certain position above the outlet openings of the filling tube, and the tube-shaped packaging material is fed continuously and vertically downward, and the pipe is held by sealing clips mi and counter-clamps in the transverse direction below the liquid level and is fed down, the pipe is sealed in the transverse direction, while the pipe is held by sealing clips and counter-clamps in the transverse direction below the liquid level, at the same time the pipe is held by forming guards for preliminary molding, then the pipe is cut into transverse sealing zone, and packaging containers are formed. The filling and packaging machine contains a pressure flange located around the periphery of the filling tube below the liquid level in the pipe-like packaging material, while the pressure flange controls the flow of liquid food product in the pipe from the bottom to the top to maintain a positive pressure of the liquid food product in the pipe below the pressure flange and to facilitate pre-molding with forming shields. The filling and packaging machine comprises a coating agent. The coating agent coats the gap or potential gap formed in the overlap of the longitudinal sealing zone earlier downstream of the place where the pressure of the liquid food product falls due to a change in the pressure of the liquid food product above the sealing clamps, counter clamps and forming shields, as well as coating agent prevents the penetration of substances from the environment into the pipe due to the pressure drop of the liquid food product caused by changes in the pressure of the liquid pi shchevy product.

In a preferred embodiment of the invention, the coating agent is a coating agent for coating.

In a preferred embodiment, the coating agent is an adhesive agent for coating.

In a preferred embodiment of the invention, the coating means is installed on the outside of the aseptic chamber to allow the liquid food product to be poured into the tube-like packaging material in a sterilized atmosphere.

Advantages of the Invention

In the machine for filling and packaging according to the invention, the web-shaped packaging material is continuously fed and takes the form of a pipe, while the pipe with an overlap of both ends of the packaging material is sealed longitudinally in the longitudinal direction, the liquid food product from the filling tube is poured to a predetermined liquid level in a certain position above the outlet of the filling tubes, and tube-shaped packaging material is fed continuously and vertically downward, wherein the tube is held transversely by sealing clips and counter-clamps below the liquid level and is fed down, the pipe is sealed in the transverse direction, while the pipe is held by sealing clips and counter-clamps in the transverse direction below the liquid level, at the same time the pipe is held by forming guards for preliminary molding, then the pipe is cut in the transverse sealing zone and packaging capacities.

Since the container is sealed in the transverse direction below the liquid level in the web-like packaging material filled with the liquid food product, no unnecessary air remains in the container, which helps to maintain good quality.

In the aforementioned filled package, the pressure of the liquid food product poured into the tube is a positive pressure proportional to the depth of the liquid from the liquid level. When forming the packaging material using molding shields at this positive pressure, the material can be formed properly.

The property of this invention is that around the periphery of the filling tube below the liquid level in the tube-shaped packaging material is a pressure flange.

When the tube-like packaging material is fed downward, the material is quickly compressed by a sealing clip and a counter-clamp, and, in addition, the material is quickly compressed by a pair of forming shields. Fluids in the tube-like packaging material impart a jerk force, the pressure of the liquid food product in the tube suddenly rises, and positive pressure can become excessive. Excessive positive pressure quickly raises the fluid level, causes erratic agitation, and leads to difficulties in controlling the fluid level.

Thus, excessive positive pressure quickly raises the liquid level and leads to unstable fluctuations in the level. Shown in FIG. 8, the float 34 swings noticeably up and down, and as a result, the control means 33 cannot control the level.

According to the invention, the pressure flange controls the flow of the liquid food product in the pipe from the lower to the upper part to maintain an appropriate positive pressure of the liquid food product in the pipe below the pressure flange and to facilitate pre-molding with forming shields. In addition, even if the liquid food product flows back from the lower portion to the upper portion, the reverse flow can be controlled, and the rapid rise in the liquid level can be controlled.

For example, around the periphery of the filler tube 1 below the liquid level in the tube-like packaging material 1, a pressure flange 36 is located, as shown in FIG. 8. Even if the liquid food product flows back from the lower portion to the upper portion, by quickly compressing the packaging material with sealing clips and counter-clamps, as well as a pair of forming shields, the pressure flange 36 can control the reverse flow and control the rapid increase in liquid level.

A feature of the present invention is the provided coating agent, wherein the coating agent is applied to the gap or potential gap formed in the overlap of the longitudinal sealing zone earlier downstream of the place where the pressure of the liquid food product falls due to a change in the pressure of the liquid food product above the molding shields.

Due to fluctuations and changes in the pressure of the liquid food product, the pressure of the liquid food product poured into the pipe around the pressure flange is at risk of an extremely low positive pressure or negative pressure.

For example, as shown in FIG. 5, the tube-shaped packaging material 1 is fed down in the direction of the arrow (c) around the outlet opening 7a of the filler tube above the transverse sealing device. As shown in FIG. 5 (A), the pipe is rapidly compressed by the forming shields, the sealing clamp 10a and the counter-clamp 11, the jolting force is imparted to the liquid in the tube-like packaging material, the pressure of the liquid food product in the pipe rises rapidly, and the liquid flows back in the direction of arrow (a). Pressure flange 36 controls the return flow.

Since the pressure of the liquid food product in the pipe is transferred to the entire liquid food product in the pipe, regardless of the pressure flange 36, as shown in FIG. 5 (B), fluid in the pipe flows in the opposite direction indicated by arrow (e) by inertia. However, the movement of fluid from the lower portion to the upper portion from the flange is prevented by the presence of a pressure flange 36, whereby there is a lack of fluid above the flange, and a shortage (d) occurs. This deficiency (d) is shown in FIG. 5 (B) as virtual foam. As a result, the pressure of the liquid food product poured into the pipe is at risk of having an extremely low positive pressure or negative pressure.

The tube-like packaging material is successively fed downward in the direction of the arrow (c), and the volume of the tube-shaped packaging material below the pressure flange 36 is increased. While the liquid food product corresponding to the increase in volume is supplied from the outlet of the filler tube 7a, the liquid above the pressure flange 36 should be supplied in the direction indicated by arrow (b) (Fig. 5 (C)). However, the pressure flange 36 prevents flow. As shown in FIG. 5 (C), when the sealing clip 10a and the counter-clamp 11 pull down the tube-shaped packaging material, the volume of the tube-shaped packaging material below the pressure flange 36 increases rapidly. The quantity of liquid food product supplied is insufficient and there is a shortage (d). This deficiency (d) is shown in FIG. 5 (C) as virtual foam. As a result, the pressure of the liquid food product poured into the pipe is at risk of having an extremely low positive pressure or negative pressure.

According to an example of a filling and packaging machine, FIG. 6 is a diagram with a vertical axis showing the pressure of the liquid food product below the pressure flange and a horizontal axis showing the time of one cycle of the transverse sealing, preforming, and cutting steps.

The pressure of the liquid food product in the pipe rises rapidly with rapid compression of the pipe with forming shields, a sealing clamp and a counter-clamp. See peaks (e) and (f). When the tube-like packaging material is fed down, the volume in the tube-like packaging material below the pressure flange increases rapidly. The amount of liquid food product supplied is not enough. The pressure of the liquid food product poured into the pipe is at risk of negative pressure. See bottom point (g).

In the above example, the pressure of the liquid food product poured into the pipe has a negative value at the bottom point (g).

A feature of the present invention is that the coating means is mounted above a sealing clip, a counter-clip, and forming shields, causing changes and pressure fluctuations of the liquid food product. This is because installation downstream of them does not make sense, and there is no place for installation in the working position of the forming shields, sealing clamp and counter-clamp.

In addition, the installation site of the coating agent is located upstream of the pressure drop of the liquid food product due to changes and fluctuations in the pressure of the liquid food product. Under these conditions, the coating agent is installed in a place with a slight pressure drop due to changes or in a place where there is no pressure drop. In other words, the coating agent is installed in a place with positive pressure and earlier downstream of the place with negative pressure.

As mentioned above, in a filling and packaging system, the pressure of a liquid food product can be very low positive pressure or negative pressure.

It is a feature of the present invention that since the coating agent is coating the gap or potential gap formed in the overlap of the longitudinal sealing zone, the coating agent prevents the entry of environmental substances (contaminants) into the pipe and maintains hygienic storage conditions of the food product.

In a preferred embodiment of the invention, the coating agent is a film coating agent that applies a coating film.

In this embodiment, the film applicator applies the film to a gap or potential gap formed in the overlap of the longitudinal sealing zone. The film applicator prevents the ingress of substances from the environment or contaminants into the liquid food product in the pipe and maintains hygienic storage conditions of the food product.

In a preferred embodiment of the invention, the coating agent is a coating adhesive. In this embodiment, the adhesive applicator applies the film to a gap or potential gap formed in the overlap of the longitudinal sealing zone. The adhesive application agent prevents the ingress of substances from the environment or contaminants into the liquid food product in the pipe and maintains the hygienic storage conditions of the food product.

In this embodiment, the adhesive application means covers the gap with a liquid, viscous, membrane, film-like adhesive using a roller, nozzle, spray gun and nozzle.

In a preferred embodiment of the invention, the coating means is installed on the outside of the aseptic chamber to allow the liquid food product to be poured into the tube-like packaging material in a sterilized atmosphere. Aseptic chamber is difficult to install in terms of mechanical design, hygiene, operation and functioning. From the point of view of mechanical design, hygiene, operation and functioning, it is optimal to install a coating agent from the outside of the aseptic chamber.

As noted above, the filling and packaging machine of the invention is capable of easily preforming with molding guards by maintaining the positive pressure of the liquid food product poured into the pipe, and is able to prevent the pressure of the liquid food product from falling to negative pressure, even if the pressure of the liquid food product decreases due to surges up and down the pressure of a liquid food product, and is able to prevent the penetration of substances from the environment into the pipe.

As shown in FIG. 7, in the filling and packaging machine of this embodiment, the web-like laminated packaging material 1 takes the form of a pipe, wherein the pipe with an overlap of both ends of the packaging material is sealed longitudinally in the longitudinal direction, as shown in FIG. 8, liquid food product poured to a predetermined level of liquid from the filling tube 7 is poured above the outlet opening of the filling tube 7 into a tube-shaped packaging material supplied vertically downward to the aseptic chamber 40, wherein when the pipe is compressed with sealing clips 10 and counter-clamps 11 in the transverse direction, as shown in FIG. 9, the pipe 1 is transversely sealed, at the same time the pipe is held by the forming shields 41 and 41 for preliminary molding, then the pipe is cut in the transverse sealing zone by the cutter 42, and preliminary containers 13 are formed.

The structure of the coating agent (film coating agent) of Example 1 of the filling and packaging machine in accordance with the present invention is shown in FIG. one.

The coating means 20 of the present embodiment is installed externally directly below the aseptic chamber 40 to allow the liquid food product to be poured into the tube-like packaging material 1 in a sterilized atmosphere.

The installation location is located above the sealing clamp, counter-clamp and forming shields (not shown in Fig. 1 and in Fig. 9, sealing clamp 10, counter-clamp 11, forming shields 41 and 41).

In the machine for filling and packaging of this embodiment, the pressure of the liquid food product drops in the lower part (downstream) below the installation site of the coating agent 20 and becomes negative pressure, while the coating agent 20 is installed at a positive pressure point earlier in place where the pressure becomes negative.

Consider the coating agent or film coating agent 20 comprises a reel 23 with tape 24 containing adhesive pads 21 and a release film 22 for rewinding and feeding adhesive pads 21, a guide 25a for guiding the tape 24 unwound from the reel 23, the separation roller 25b, peeling the separation film 22 from the adhesive pads 21, the pressure roller 26, pressing the adhesive pads 21 to the gap in the overlap of the longitudinal seal, the withdrawal roller 27, collecting the separation film 22, d a sensor 28 for detecting an overlap of the longitudinal seal, a control means 29 that controls the time of peeling of the release film 22 from the adhesive pads 21 and applying the adhesive pads 21 from the adhesive film to the overlap gap.

The film applying means 20 is equipped with a tape 24 comprising adhesive pads 21 and a release film 22 for rewinding and feeding the adhesive pads 21. Adhesive film pads 21 comprise an adhesive layer and a backing. In the tape 24, the adhesive layer is temporarily attached to the release film.

The tape 24 is unwound from the reel 23, and the guide 25a guides the tape 24. On the separation roller 25b, the tape 24 peels off the separation film 22 from the adhesive pads 21. The overlay 21 of the high-adhesive film is supplied directly and peels off the flexible release film 22, since the release film 22 makes a U-turn on the release roller 25b.

Directly applied adhesive pad 21 enters the outer surface of the tube-like packaging material 1 and is attached to the overlap of the longitudinal seal. The attached adhesive film pads 21 are pressed against the overlap gap of the longitudinal seal by the pressure roller 26. As a result, the gap is covered by adhesive film pads 21.

The release film 22 pivots on the release roller 25b, and then the release film 22 is picked up by the withdrawal roller 27.

In this embodiment, a sensor 28 is installed that detects an overlap of the longitudinal seal. Using signals from the sensor 28, the control means 29 sets the delamination time of the release film 22 from the adhesive pads 21, and the adhesive pads 21 are pressed onto the overlap gap.

FIG. 2 is a sectional view showing a gap occurring in an overlap of a longitudinal sealing zone.

With continuous packaging and pouring, it is necessary to overlap with the next regular web-shaped packaging laminate, since the length of the web-like laminated packaging material is not infinite. In FIG. 2 (a) shows a longitudinal section of an overlap 1c of a web-like laminated packaging material 1a and 1b, and their overlapping in an overlap 1c.

FIG. 3 is an external view of a paper tube in which an overlapping gap in the longitudinal sealing zone is coated with a film by means of a film applicator.

In this embodiment, the web-like packaging material 1 takes a tube-like shape, both ends of the packaging material are superposed on each other in the longitudinal direction of the pipe, longitudinal sealing is performed, and a longitudinal sealing zone 1d is formed.

In FIG. 2 (b) shows a cross-sectional view of an overlap of a longitudinal sealing zone 1d of a web-like laminated packaging material 1a and 1b.

Due to the overlap of both ends, the overlap 1c of the inner and outer web-like laminated packaging material 1a and 1b is superposed. As shown in FIG. 2 (b), an overlap 1e is formed in the overlap 1c. At a gap 1e, the inner side of the tube-like packaging material 1 can be connected to the outer side of the tube-shaped packaging material 1.

Adhesive film pads 21 cover the gap 1e arising in the lap 1c of the longitudinal seal 1d by the film applying means 20, as shown in FIG. 3.

Since the film applicator covers the film with a potential gap or a gap that occurs in the overlap of the longitudinal sealing zone, any external atmospheric pollutants do not penetrate from this point, no contamination of the liquid food product in the pipe occurs, and the sanitary and hygienic conditions of food storage are maintained.

The outer side of the adhesive coating by the adhesive application means is shown in FIG. four.

The adhesive unit 21a covers a gap 1e arising in the overlap 1c of the longitudinal seal 1d of the tube of the packaging laminate 1a and 1b by means of an adhesive application (not shown), for example, as shown in FIG. four.

Since the adhesive application means covers the potential gap or gap arising in the overlap of the longitudinal sealing zone with adhesive block 21a, any external atmospheric pollutants do not penetrate from this point, no contamination of the liquid food product in the pipe occurs, and the sanitary and hygienic conditions of food storage are maintained.

Liquid, viscous, membrane and film-like adhesives are applied to the gaps using a roller, nozzle, spray agent, spray nozzle.

In addition, the invention is not limited to the above embodiments, the embodiments may be modified based on the object of the invention in accordance with the scope of the invention.
