Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filling machine for making a pouch from a film and filling the pouch with a filling material, and particularly for filling the pouch in an aseptic state while transporting the pouch laterally. Regarding aseptic filling machines.

Generally, an apparatus for automatically filling liquids such as soft drinks, juices, milk, or other viscous substances into pouches formed from film materials is vertically shaped as shown in FIG. That is, a filling liquid is supplied into a cylindrical bag 1 from a filling tube 2, an appropriate position of the bag 1 is bonded by an adhesive device 3, and then the bonded portion is cut by a cutter 4 to increase the number of filled products 5. That's what I do.

Such a vertical filling device is designed to adhere and cut the film with the liquid 6 filled in the cylindrical bag 1, so that the filling liquid gets into the adhesive part and the adhesion is sufficiently performed. In addition, filling with a liquid containing solids cannot be done by punching out if the same shape is caught in the adhesive part and adhesion is impossible.

Therefore, if the optical product is a liquid, there is a limit to the size of the product, and it is impossible to fill the product with liquid containing solids.

Furthermore, in FIG. 1, a feeding device (7: c L shown in the drawing) for intermittently lowering the bag 1 is provided near the layering device 3 and the cutter 4. At the beginning of filling, it is necessary to sterilize the cylindrical bag 1 while it is held in the feeding device (enveloping the filling tube 2), so the sterilization of the inner and outer surfaces of the filling tube 2 is shown in Figure 2. As shown in the figure, steam, hot air, etc. are passed through the filling tube 2 from its branch pipe 8, and the steam is directed upward by the reflecting plate 7 at the lower end of the filling tube 2. 2. Requires special equipment for aseptic processing.

In view of this, an object of the present invention is to provide an aseptic filling machine that can manufacture filling bags in a completely sterile state, and can seal not only liquids with a capacity of about 31 cm, but also liquids containing solids, in a completely sealed state. shall be.

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

In FIG. 3, the aseptic filling device M according to the present invention includes a film supply section 1 for feeding a film f of synthetic resin or the like;
A film sterilizer 2 that sterilizes the film f;
a pouch manufacturing section 3 for producing pouches from sterilized film; a filling section 4 for filling the pouch with a filling material; a discharging and collecting section 5 for discharging and collecting the filled product after filling; The pouch manufacturing section 3, the filling section 4, and the discharging and collecting section 5 are housed in an airtight chamber 6, and a control section 7 is installed on the sterile chamber 6 to control each process. .

The film supply section 1 includes a roll holding section 9 for holding a film roll lt, and the film sent out from the roll 1 is transferred to a film plowing plate 10i [a film storage R for storing the film]. This reaches section 11. This storage section work 1 allows the film to have some extra space, especially the splicing plate 10-
When adding a new roll to an old roll using H,
The dancer roll 12 is raised to continuously feed out the film even if no film is supplied from the roll R.

The film sterilizer 2 has a tank 13, in which a 30% aqueous solution of H2 (J2) is stored, and this H2O2 solution is indirectly heated to 50 to 60°C by passing hot water 1 inch around the tank. The tank capacity is set so that the film passes through H2O2 in about 10 seconds.A film drying device 14 is provided above the tank 13. teeth,
As shown in FIG. 4, there are scraping nozzles 15, 15 for blowing cold air downward to scrape off the H2O2 liquid on the film, and a drying nozzle installed above the nozzles 15 for blowing out hot air. 16, 16 and further nozzle 1
6 and heating rollers 17, 17 provided above.

A drying process 14 is provided in a sterile chamber 18, in which the dried sterile film passes through a triangular plate 19 for folding it in half. This triangular plate 19 has a shape as shown in FIG. 5, and the position of the upper surface of the folded film f is adjusted by moving this triangular plate 19. That is, the triangular plate 19 is made vertically movable because the top surface position of the film when folded up varies depending on the width of the film to be processed, so the top surface position of the film is always kept constant regardless of the width of the film. This is to set the opening at a constant height when it is made into a bag.

Film f1 folded up into two pieces by triangular plate 19
As shown in FIGS. 1 and 6, the bottom side of the film f is sealed by bottom sealers 21, 21, which have heaters located at the bottom of the film and narrow from both sides of the bottom of the film to seal the bottom of the film f. . Note that this bottom sealer 21 is not necessarily required and may be provided as necessary.

The bottom-sealed film fl is then sealed on its side by a side seal 22.22 with a vertical bottom sealer, forming the side-sealed film f1.
The side seal portion is further cooled by a side cooler 23.23 provided downstream of the side seal.

On the downstream side of the side cooler 23, a notched punching member 24 is provided.
, 24 are provided, and one of the members 24 is provided with a blade 24a for forming a minus notch in the side seal portion.
is provided.

Film fl s fl feed rollers 25, 25
The film f1 is fed to the downstream side by the feed roller 25 and is cut at the center of the side sealer portion by cutters 26, 26 (rotary cutters may be used) to form a bag 27 with the −F portion open. The separated bag 27 is held by claws 28, 28, and the claws 28 are reciprocated in the flow direction of the bag 27 by a transport device (not shown).

Note that the notch n punched out by the notch punching member 24
is formed to cross the cutting line 1 between the bags as shown in Fig. 7, and this notch is introduced when the consumer cuts off the opening of the bag after filling the bag with the filling and making it into a product. Perforated to form a cut.

The filling section 4 is provided with a filling device 29 as shown in FIG. 3 and FIG.
For example, liquid is filled into the bag 27 from a.

Further, a conveying cheno 30 is configured to run between sprockets 31 and 31 along the flow direction of the bags 27 in the filling section 4, and this cheno 30 has holding arms 32 for holding both sides of the bags 27. This holding arm 32 receives the bag n carried by the claw 28 at position a in FIG. 3, passes through position b, and conveys it to the filling position at position C. C
When the bag is filled with the material at the position, the mouth of the bag is opened by an opening device (not shown), and the bag 27 is filled while being supported at its lower part on the support conveyance belt 33 and its sides by the side support plate 34. After filling, the bag 27 is closed and degassed at position d.
It is top sealed by the top seal 35 at position e. The top-sealed filled product is released from the holding arm 32 at position g and is discharged and collected from the chute 36 to the outside.

In addition, several H2O2 spray nozzles (not shown) for pre-sterilization are formed in the sterile chamber 6, and the inside of the sterile chamber 6 is sterilized and dried with hot air after spraying (202). Clean air supply ports 37, 37 are provided at the upstream and downstream ends, and these supply ports 37
In order to maintain the inside of the chamber in a sterile state, the air flows out through the entrance and exit of the film f or the bag 27 to keep the inside of the chamber at a positive pressure. Note that a clean air outlet is formed in the front chamber 18''2 provided at the upstream end of the chamber 6.

The film f and the bag 27 advance intermittently, and in this way, the filling material is filled and collected one after another into the bag n under aseptic conditions, but the equipment for each of these steps is controlled by the control section 7, and the entire process is controlled by the controller 7. Automated.

In the present invention, since the flow of the film or bag is horizontal, it is possible to perform bottom sealing or side sealing before filling, and after these seals, the filling material can be filled and the bag can be top sealed. It is possible to make the product larger and fill it with a large amount of filling material, and since all processes are performed in a sterile chamber, it is easy to maintain sterile conditions. No special equipment as shown in Figure 1 is required in addition to the normal pre-sterilization equipment.

Since the present invention is configured as described above, it has the advantage that both large-sized products and products filled with solid matter can be manufactured easily, continuously, and quickly under aseptic conditions.
