2. Description of the Related Art As a technique for molding a bag-shaped container with a port from a cylindrical plastic film (inflation tube) which is continuously formed into a cylindrical shape, for example, a bag-shaped container 11 for infusion as shown in FIG. 1 is manufactured. In general, an inflation tube (hereinafter, also simply referred to as a tube) is heat-sealed in the width direction of the tube at a predetermined interval in the longitudinal direction, and this is cut to open one end and seal the other end. 2 "is formed in the bag opening, and a flat bag 2" is formed.
It is manufactured by inserting a port 4 made of a plastic cylindrical body such as a hard polyethylene as shown in (3) and welding it to the mouth of the bag 2 ″ to use as a spout of a liquid material at the time of use.

A technique for inserting and fixing the port 4 in the opening of the bag 2 "in this case is, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Laid-Open Patent Publication No. 131573/1999, a bag placing table that stores and positions the bags one by one is used, and the port is inserted from the opening of the bag opening while moving the bag placing table over each process, and separately. This port and the bag opening are welded together by using a heating / pressurizing means or the like arranged in.

[0004]

However, in the above-mentioned conventional technique, since the bag placing table for accommodating and fixing the bags one by one is used, the overall volume of the bag-making device with the port is reduced. There is a problem that the size becomes extremely large, and in addition, a transport mechanism (conveyor) for intermittently moving the bag placing table becomes large. In addition, since the port must be moved and inserted toward the opening of the bag held on the bag mounting table, a port moving device that moves according to the bag mounting table is required, and the entire device is larger. And there was a problem that it became complicated. The present invention is a continuous bag-making and filling apparatus for bag-shaped containers with a port, which simplifies a bag placing table, a large-scale transfer conveyor for intermittently moving the bag placing table, and a complicated apparatus attached to the bag placing table to make the entire apparatus compact. It was made as an issue to provide.

[0005]

As a means for solving the above-mentioned problems, a continuous bag-making and filling apparatus for bag-shaped containers with ports according to the present invention,
A flat tubular film is provided with a pair of cutters that cleaves and tears both ends in the width direction of the tubular film along the flow of the tubular film from the upstream side to the downstream side in the flow direction. A port fitting means for fitting the distal end side of the port supported by the port support portion into the cleaving part, facing the cleaving cleaving part on the downstream side of the cleaving cleaving part by the one-side cutter of the tubular film. And a one-sided re-sealing means for resealing the cleaved portion near the fixed port by heating, while the other side cutter of the tubular film is It is arranged on the downstream side of the resealing means, and on the downstream side of the cleavage tearing portion by the other side cutter, one end is inserted inward through the cleavage tearing portion and the other end is treated.

This filling nozzle is provided with another side re-seal means for heating and re-sealing the cleavage / cleavage part by the other side cutter on the downstream side in the vicinity of the insertion section, and the both side re-seal means is provided on the downstream side of the other side re-seal means. A width seal means for intermittently heat-sealing the tubular film after stopping over the entire width in the width direction, and a separating means for separating the width seal portion by the width seal means into an upstream side and a downstream side, It is a feature.

With such a structure, a bag with a port is continuously manufactured using a tubular inflation film, which has not been realized up to now, and the object to be treated is dusted. It is possible to obtain a bag-making and filling device with a simple structure that can be filled without the inclusion of bacteria and bacteria. In this case, preferably, the separating means has a known combination structure of a pressing anvil and a protrusion of a cutter knife, which also serves as a cooling means for cooling the width seal portion, and the welding of the heat seal portion of the bag-finished product is performed. It is good because it can be cut into a solid state.

[0015]

Next, the operation of this embodiment will be described. The explanatory view showing the flow of the tubular film 2 in FIG. 5 shows a case where a plurality of bags are continuously made into bags and the filling process is carried out. For convenience, a manufacturing and filling process operation for one bag will be described with reference to FIGS. 1 to 4. .

Using the continuous bag-making and filling apparatus 1 (hereinafter, also simply referred to as a filling apparatus) for the bag-shaped container 11 with the port shown in FIG. 4, the roll film 2'and the feed roll 15 are fed by intermittent driving. The flat tubular film 2 is subjected to predetermined printing by the printing means 16 on the surface thereof, and then one side end 2A of the film 2 is cut by the cutter 3A to form a split portion 3A '. The cleaving part 3A ′ is inserted with the expanding member 12 in advance before the main operation of the filling device 1 is started, whereby the cleaving part 3A ′ of the film 2 is expanded by the transfer of the film 2. And is expanded to a size that facilitates fitting of the port 4 into the cleaving portion 3A ′ on the downstream side.

Next, when the cleaving part 3A 'reaches the position where it faces the port fitting device 5 and is in a stopped state, the port supply means 5P of the port fitting device 5 operates and the air cylinder 20 and the port gripping part in FIG. Port 4 gripped by 19
Is inserted into the cleft 3A '. The film 2 fitted in the port 4 is transferred to the next port heat sealing means 6 by the intermittent drive of the feed rolls 15 and 15,
Is fixed to the dehiscence portion 3A 'and the peripheral dehiscence portion of the port 4 is resealed on the downstream side thereof by the resealing means 7 and 7'.

As described above, after the port 4 is fitted into the one end 2A of the film 2 and resealed, the film 2 is then cut at the other end 2B by the other cutter 3B during transfer. The opening 3B 'is formed. Since the filling nozzle 8 for filling the object to be treated from the outside to the inside of the film 2 is previously inserted into the cleaving portion 3B ′, the film 2 crosses over the filling nozzle 8 at the cleaving portion 3B ′. Transferred in the state,
Immediately after passing through the filling nozzle 8, the cleft 3B 'is sealed by the other-side resealing means 21, 21'.

That is, at this time, the film 2 has the shape of the substantially cylindrical film 2 in which the port 4 is fitted and fixed to the one end 2A and the other end 2B is sealed.
Then, the substantially tubular film 2 is sealed in the width direction of the film 2 by the width sealing means 9 arranged next to form a bottomed tubular state. After that, the object to be treated is discharged and filled from the filling nozzle 8 into the bottomed cylindrical bag. The bottomed cylindrical bag filled with the object to be processed is further transported to the downstream side, and the upper part thereof is sealed by the width sealing means 9 to the entire width, thereby being manufactured as a sealed bag-shaped container 11 with a port.

In the embodiment of the present invention, the bag-shaped container 11 with ports is manufactured in a state in which a plurality of width seal portions are connected. Therefore, the width seal portion is separated from the separating means 10
If the entire width of the film 2 is cut by, the bag-shaped container 11 with a port is separated as an independent individual. And
The bag-shaped container 11 with a port is manually taken out from the end of the carry-out conveyor 17 shown in FIG. 4 or is transferred to another conveyor to be collected.

As described above, according to the present invention, both sides of a flat tubular film are cleaved and cleaved, a port is attached to the cleaving part at one end, and a cleaving part at the other end is cleaved. Since the part is used as the insertion part of the object filling nozzle to immediately reseal each cleaving part, the bag-shaped container with a port can be obtained as a product in which germs, dust, etc. are not easily mixed. . Therefore, these products can be safely provided to the market as a bag-shaped container with a port filled with foods, medicines and the like. In addition, the configuration from port insertion to completion of filling can be simplified, and the manufacturing cost can be significantly reduced.
