Description

Detailed Description of the Invention The present invention enables fully automatic packaging in which a film packaging container with a spout is manufactured in a series of steps, and at the same time filling and heat sealing of contents such as liquids and viscous substances are carried out completely continuously. The present invention relates to an apparatus for manufacturing a film package with a spout.

Film packaging, which has been on the market in larger quantities than before, is simply a film packaging container filled with contents and heat-sealed without a closure, so once opened, it can be stored for a long time. Therefore, packages with a stopper that allows the contents to be used as much as necessary have been developed, and some are already on the market. Typical packaging containers with a spout include a method in which a spout is attached to a hole in a suitable corner of a three-sided or four-sided sealed packaging bag (the film is usually a multilayer composite), or a pre-manufactured packaging bag. A spout molded into a convenient shape by injection molding etc. is inscribed in the upper opening of the body,
It is manufactured by welding it and sealing the opening. However, these methods require the labor-intensive work of refilling the contents in the processing process after attaching the spout, and are designed to reduce manufacturing costs. There was a flaw in not being able to get it.

In view of the current situation, the present invention provides a punching device section that sequentially drills through holes for attaching a plug at predetermined intervals along the longitudinal direction of a long synthetic resin film, and a hole that is larger than the through hole. a spout supply/insertion device section for supplying and inserting a spout with a cap smaller than the through hole and having a synthetic resin base; a spout welding device section for welding the synthetic resin base of the spout to the film; , a vertical sealing device unit that vertically seals the film by folding both side edges f:M together to form a cylinder, and a horizontal sealing/film transporting unit that horizontally seals between each port plug and intermittently transports the film. In an apparatus for producing a film package with a spout, which comprises a device part and a contents filling device part, the entire punching device part has a fixed female blade whose blade is the edge of a hole having a shape to be punched; 1. The lower end is provided with a blade part that can come into sliding contact with the blade part of the female blade body, and a gas spout, and is moved up and down by a drive member. By forming a movable male blade with a movable male blade, it is possible to manufacture film packaging with a spout at high speed and fully automatically, allowing the contents to be used economically in small quantities. And, it is possible to provide an apparatus for producing a film package with a spout, in which film fragments can be removed and removed using gas from a gas outlet in a perforation device.
The present invention will be explained in detail below according to the illustrated embodiments. In the figures, 1 is a long synthetic resin film, and although the required quality varies depending on the application, it generally has pinhole resistance and gas barrier properties. Use films that have the various performances required for packaging films such as gender.

The synthetic resin film may be a single film of polyolefin or the like, but it is particularly desirable to be a composite film of two or more layers that has the characteristics of multiple films. The structure of the composite film can be stacked during vertical sealing by either "Gassho pasting", in which both edges of the film are placed in contact with the inner surfaces, or by placing both edges of the film in such a way that the inner and outer surfaces are in contact with each other. It depends on whether you want to use "envelope pasting" to overlap. When overlapping both edges of the film in a gassho-attached manner, as a minimum, a polyolefin film that is safe for food hygiene and has good heat-sealing properties for the contents should be used to ensure the characteristics necessary for the packaging container. A composite film is used in which a film that functions as a base film with pinhole resistance, gas IJ properties, etc. is used as another layer. When stacking both sides of the film to form an envelope, use a polyolefin film that is food hygienic for the contents and has good heat-sealing properties, a film that can be heat-sealed as well as a base film. A composite film of at least three layers laminated in this order is used.

First, the long film 1 is intermittently pulled out from the film roll 2 by the transverse sealing and film transporting device section 3. The horizontal sealing and film transporting device section 3 is configured to perform horizontal sealing while gripping and pulling the long film 1 intermittently,
In Fig. 1, A, A...D, D indicate the respective states of the horizontal 7-lever of the horizontal seal/film transfer device section 3, which grips the entire long film 1 and descends, and releases and ascends. A, A, B, and B indicate the timing position (starting position of grasping operation) and grasping position (starting position of lateral sealing and traction operation), respectively, and C9C and 9, D indicate the lateral sealing and traction operation, respectively. 0 to 4 indicating the end position (release operation start position) and release position (timing position A, return operation start position to A) are printed on the long film 1 at intervals corresponding to the width of the final package. It is a sensor that optically detects marks that have been detected, and consists of a light emitting part and a light receiving part.According to the detection signal of this mark, the horizontal seal bar of the semi-seal/film transfer device part 3 moves from B, B to C9C. The lateral seal bar of the lateral seal/film transfer unit 3 completes both the traction and lateral seal operations.
The process returns to A and A via KD and D and waits for a predetermined time when all the work in each process that starts in conjunction with this completion is completed, and after the predetermined time, the next gripping and pulling operation is automatically completed. The traction operation continues until the next mark detection signal is detected.

5 is a defect in the film gripping and stopping device section which starts its operation according to the detection signal of the mark, but does not stop immediately due to elongation of the long film 1 even when the horizontal sealing and film transporting device section 3 finishes the pulling operation.・The long film 1 is stopped at a predetermined position accurately and immediately.

In this way, the film roll 2 is intermittently pulled out, and the -g long film 1 is first guided to the punching device section 7 through the guide roll 6°. The perforation device section 7 includes a fixed female blade 7 fixedly mounted below the running position of the long film 1 within a frame 8 that guides both side edges of the long film 1 and causes the long film 1 to run, and a frame. A movable male member is fixed on the frame 8 through a support base 9, and is moved up and down by a drive member 10, and is disposed above the running position of the long film 1 through the frame 8. It mainly consists of the mold blade body 7□.

The fixed female blade body 7 is provided with a through hole 11 corresponding to the shape to be drilled (usually circular), and the edge of the soil for forming the through hole 11 is made into a blade portion 12. The movable male blade body 72 is provided with a hanging blade part 13 in sliding contact with the blade part 12 at the lower end, and a piston-shaped large diameter part 15 with a diameter t''L in sliding contact with the cylinder 14 of the drive member 1o. Gas is alternately supplied and discharged through gas inflow and outflow pipes 16° and 16' with three-way valves 32 and 32' arranged above and below the σ2Jt cylinder 14, which is in the shape of a long rod and sealed with gland packing for rod sealing. A movable male blade 72 in the form of a long rod.
A passage 18 for gas to be supplied through the entire rubber hose 17 is formed in the axial center of the rubber hose 17, and a gas spout 19 is formed at the lower end. The cut film pieces can be separated and removed from the entire long film 1 by the gas ejected from the gas outlet 19 at all times or during perforation, and the cut film pieces will not adhere to the long film 1 due to the generation of static electricity. prevent,
Interference with the following operations or contamination with the final packaging container can be avoided. By lowering the movable male blade 72 when the long film 1 is stopped, a through hole for attaching a spout is bored in the long film 1. The through holes are bored at predetermined intervals along the center of the long film 1 or along any longitudinal direction (in FIG.
/4 position).

Next, the perforated long film is sent to the net plug supply and insertion device section 20. The spout 21 is screwed into a generally cylindrical spout body 211 with a smaller diameter than the through hole, a large-diameter pedestal 21□ connected to one end thereof in a brim shape, and a male screw provided on the outer periphery of the spout body 21□. It consists of a cap 213 equipped with a female thread. The base 21□ is preferably made of the same material as the film forming the inner surface of the packaging container so that it can be easily sealed. -Also, the material of the cap 213 is the same as that of the spout body 21 in order to make it easy to open when opening. It is desirable that the spout body 211 be made of polyethylene, and the cap 213 be made of polypropylene. The spout insertion and supply device section 20 has the spout 2 with the pedestal 21□ facing up and the cap 213 facing down.
1 are lined up in a predetermined position one by one from a parts feeder, which is fed out.The spout 21 is vacuum-suctioned one by one and transported onto the long film 1.The suction force is released and the long film is fed out as shown in FIG. Insert into hole 1.

In this way, the long film 1 with the plug 21 inserted
is sent to the plug welding device section 22. Plug welding device section 22
As a result, the base 21□ of the spout 21 in FIG. 4 and the upper surface of the long film 1 (inner surface of the final packaging container) are thermally welded. Although any means may be used for thermal welding, ultrasonic means can thermally weld efficiently without thermally deforming the base 21 □, so the desired force is within %.

Reference numeral 23 designates a heat-sealing table having a recess into which the spout 21 can fit, and moves up and down for each seal to ensure sealing, and also serves to prevent the film from being pulled or wrinkled due to the movement of the spout 21. accomplish

Reference numeral 24.24 is a guide roll, and a concave groove corresponding to the shape of the guide roll is bored at the position through which the spout 21 passes, so that the film can be transferred smoothly.

Reference numeral 25 is a guide plate for fine adjustment to introduce the film to a desired position that will be installed in the next process, and is attached to the long film 1.
(ii) The concave groove along the running direction of the spout 21 is biased. The installation position and length of the guide plate 25 should be appropriately designed as necessary.

After passing through the guide plate 25 and the guide roll 24, the long film 1 is then introduced into the vertical sealing device section 26. The vertical sealing device section 26 consists of a cylindrical guide 27 coated with an anti-adhesive material such as polytetrafluoroethylene, and heat sealing members 28 and 29 disposed near the cylindrical guide 27. Cylindrical guide 2
At step 7, both side edges of the long film 1 are overlapped by the positioning mechanism in a gassho-like or envelope-like manner, and the overlapped portion is fed without wrinkles, and at the same time, the position of the overlapped portion is determined accurately. Heat sealing is performed by adjusting heat sealing members 28 and 29. In FIG. 1, with the spout 21 attached at a position 90 degrees i'' from the overlapping part, both edges of the long film 1 are overlapped so that the two sides of the long film 1 are joined in a clasped manner. An example is shown here.Heat seal member 28.2 in this case
Reference numeral 9 denotes a heating member 28 having a U-shaped cross section for heating the overlapped portion, and a pair of sealing pressure rolls 29 for crimping the heated end portion. When heat-sealing the edges of both sides overlapped in an envelope-like manner, the cylindrical guide 27 is used as a seal receiver, and the constantly heated heating member 28f is pressed against the overlapping portion of the film when the long film 1 is stopped. It's okay.

Next, the cylindrical long film 1 that has been vertically sealed is sent to a horizontal sealing process. The lateral sealing/film transfer device section 3 has a heat sealing function, and sequentially performs lateral sealing (lower cooling) f: while flattening the long film 1 at its gripping position and sending it downward. Note that the direction of flattening of the cylindrical long film 1 is desirably selected so that the spout 21 is located at one side edge of the flat film.
30 is a content delivery pipe for introducing liquid, viscous material, etc. into the bag, and a metering pump is connected to the base end of the pipe, and when the lower part is formed in the horizontal sealing process, ○The capacity regulating press plate attached to the horizontal seal and film transfer device section 3 allows the cylindrical film containing the contents to be pressed from the outside at a predetermined position, and a certain amount of content is kept. As objects are left below the cylindrical film,
The excess contents are pushed upwards of the cylindrical film, and in this state, an upper seal (which also serves as the next lower seal) is made, sent downward, and cut by a cutter 31 at the horizontal seal portion.

Thus, the plugged film package is usually continuously
Although it can be manufactured at a rate of 5 to 30 bags per minute, a wide variety of packages can be obtained by changing the materials, the size ratio of the final package, etc. In particular, as shown in Figure 5, the closure can be A tube with a shape similar to a normal laminate tube attached to the lengthwise tip of the tube can be obtained, and ζ et al. This has helped prevent process troubles such as contamination of the surface and accumulation of cut film pieces. In addition, the long film used to manufacture packaging containers can be made not only in a single row but also in double rows, and the horizontal seal can be shared, making equipment costs relatively low. This can significantly improve manufacturing efficiency.

As is clear from the above description, according to the present invention, the film package with a stopper that allows the contents to be used economically in small quantities can be produced at 15 to 30 bags/min in a single row, and 15n to 30n bags/min in n rows. It is now possible to manufacture products at high speeds of just minutes, and in a fully automatic manner that greatly streamlines the conventional cottage industry work.It also eliminates the possibility of cut film pieces getting mixed into the packaging surface, which can easily cause defects in this type of manufacturing equipment. 0 that could have been prevented
