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 with liquid, viscous material, etc. and heat sealing are performed continuously. The present invention relates to an apparatus for producing a film package with a cap.

Conventionally, the film packaging products that have been on the market in large quantities are 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 spout that allow the contents to be used as much as necessary have been developed, and some are already on the market. A typical packaging container with a spout is a method in which a spout is attached to a hole in a suitable corner of a three-sided sealed or four-sided packaging bag (the film is usually a multi-layered composite), or a pre-manufactured package. The bag is manufactured by a method in which a spout formed into a desired shape by injection molding or the like is inscribed in the upper opening of the bag and then welded to seal the opening. However, these methods only allow for a break from the ``11 handmade'' type of work, which requires the labor-intensive work of attaching the spout and filling the contents in a separate process after ζ, reducing manufacturing costs. The flaw was that it could not be measured.

In view of the current situation, the present invention provides a perforation device section that sequentially perforates holes for attaching a plug at predetermined intervals along the longitudinal direction of a long synthetic resin film, and a perforation device section for sequentially perforating holes for attaching a plug to a long synthetic resin film at predetermined intervals along the length of the long film. a spout supply/insertion device for supplying and inserting a camp-type spout smaller than the through hole, which is equipped with a large synthetic resin base; and a spout welding device for welding the synthetic resin base of the spout to the film. a vertical sealing device section that overlaps both side edges of the film to form a cylindrical shape and seal it vertically; and a horizontal sole and film transfer section that performs a horizontal seal between each spout and intermittently transports the film. In an apparatus for manufacturing a film package including a spout, which includes a device section and a contents filling device section, the spout supply and insertion device section is connected to a spout alignment member that aligns the spouts and a top end of the aligned spouts. Accept only the first one, stop it at that position with a friction stop member, and resist the friction of the friction stop member along a transfer path that can be transferred by a pushing member in a direction different from the alignment direction of the plugs. A plug supplying member that transfers and supplies the plugs one by one to predetermined positions, and a plug conveying and inserting member that transports and inserts the plugs at predetermined positions into the through holes of the long film. The present invention will be described in detail below according to the illustrated embodiment, which enables continuous production by reliably feeding and inserting the plugs one by one.

In the figure, 1 is a long film made of synthetic resin, and although the required quality varies depending on the application, it generally has various performances required for packaging films such as pinhole resistance and gas barrier properties. use something 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 composition of the composite film is either ``gassho pasting'', in which both edges of the film are overlapped so that the inner surfaces touch each other, or the edges of both sides of the film are overlapped, so that the inner surface and the outer surface are in contact with each other. It depends on whether you want to use "L paste". When overlapping both edges of the film in a gassho manner, use a polyolefin film that is food hygienic safe for the contents and has good heat sealability as a minimum, and that has the characteristics necessary for the packaging container. A composite film is used in which a film that functions as a base film with certain pinhole resistance, gas barrier properties, etc. is used as another layer. If the overlap of both edges of the film is used as an envelope sticker, it is safe from a food hygiene perspective for the contents.
In addition to a polyolefin film with good heat-sealability and a film as a base film, a composite film of at least three layers in which heat-sealable films are laminated in this order is used.

First, the long film 1 is transferred from the film roll 2 to the horizontal sealer 31 in the horizontal sealing and film transfer device section 3.
, 31 intermittently. The horizontal sealing and film transporting device section is configured to perform horizontal sealing while intermittently gripping and pulling the long film 1, and is designated as A in FIG.
A...D, D are a horizontal seal/film transport device section 3 that grips the long film 1 and descends, releases and ascends.
The figure shows the operating states of the horizontal sealers 31 and 31, where A, A and B, B respectively indicate the waiting position (gripping operation start position) and gripping position (horizontal sealing and pulling operation start position). , C1C, and D indicate the end position of the lateral sealing and pulling operation (release operation start position) and the release position (wait position A, return operation start position to A), respectively.

A sensor 4 optically detects marks printed on the long film 1 at intervals corresponding to the width of the final package, and is composed of a light projecting section and a light receiving section. In accordance with the detection signal of this mark, the horizontal seal /<-31,3] of the horizontal seal/film transfer device section 3 completes both the traction and horizontal seal operations from B and B to C9C. In addition, the horizontal sealer 3], 31 of the horizontal sealing and film transfer device section 3 is operated after the completion of both the pulling and transverse sealing operations until a predetermined time when all the work in each process that is started in conjunction with this completion is completed. Garlic,
After returning to A and A via D and waiting, the next gripping and pulling operation is automatically started after the predetermined time, and the pulling operation is continued at the detection groove of the detection signal of the next mark.

Reference numeral 5 denotes a film gripping and stopping device section which starts the long film gripping operation according to the detection signal of the mark;
horizontal sealer 31 of the film transfer unit 3, 3.
This function works to avoid a defect in which the long film 1 does not stop immediately due to elongation even after finishing the pulling operation, and to stop the long film 1 accurately and immediately at a predetermined position.

In this way, the long film 1 which is intermittently pulled out from the film roll 2 is first guided to the punching device section 10 via the guide rolls 6.degree.

The punching device section 10 mainly consists of a fixed female cutter 11 having a through hole corresponding to the shape to be punched (usually circular) and a movable male cutter 12 that moves up and down. Through the operation of the cutter 12, a through hole for attaching a plug is made, and the long film 1 that has been punched is sent to the plug supply and insertion device section 20. By the way, mouth plug 7
For example, a generally cylindrical spout body 71 having a smaller diameter than the through hole, a pedestal 12 connected to one end of the plug body 71 in a brim shape and having a larger diameter than the through hole,
It consists of a cap 7 having a female thread that is screwed into a male thread provided on the outer periphery of the plug body 71.

The base γ2 is desirably made of the same material as the film forming the inner surface of the packaging container so that it can be easily sealed. In addition, the material of the cap 7 is desirably different from that of the spout main body 71 from the viewpoint of ease of opening.For example, the material of the cap 7 is polyethylene, the cap 75 is made of polypropylene, etc. use

The spout supply/insertion device section 20 is a so-called parts feeder that aligns articles by a spout alignment member 21, a spout supply member 22, and a spout conveyance/insertion member 23.
With this spout alignment member 21, the spouts 7 are aligned while gradually ascending the slope along the outer peripheral wall surface, and a spout with the pedestal 72 facing up and the cap 7 facing down is selected to align the spouts at the outlet. They are arranged in a line on the rail 24. Since the spout alignment rail 24 is slightly lowered and the vibration of the spout alignment member 21 is transmitted, the spout γ on the spout alignment rail 24
are pushed from behind and lined up without any gaps. In addition, in FIG. 2, the cover 2 is shown to show the alignment state of the spout 7.
Although 5 is shown with a portion cut away, the cover 25 extends at 1 on the spout alignment rail 24 to prevent the spout 7 from coming off from above due to vibration.

The spout supplying member 22 has an opening 26 on the side that receives only the first one of the spouts aligned on the spout alignment rail 24, and can be transferred in a direction substantially perpendicular to the alignment direction of the spouts 7. A transfer path 27 is provided. 28, by using a friction stopping member with a friction material such as a brush attached to the lower part, the spout 7 received into the transfer path 27 through the opening 26 receives lateral vibration from the next spout 1, and is moved into the transfer path 27. , and the next plug 7 is connected to the transfer path 2.
7 to prevent it from entering. As friction materials, Niblastik brushes, artificial grass-like materials, rubber plates, and various other materials are used. In the figure, a friction stop member 28 is shown above the spout 7 received in the transfer path 27.
is arranged so that the tip of the friction material is always in close contact with the top surface of the spout 7 with a moderate static friction force, but the friction material may be placed in close contact with a portion other than the top surface of the spout 1. Further, the friction material may be brought into close contact with the other or removed at appropriate timing.

A pushing member 29 pushes the plug γ along the transfer path 27 to a predetermined position against the frictional force with the friction stop member 28. As mentioned above, only one plug 7 is received into the transfer path 27 through the opening 26 and stopped, so the pushing member 29 only pushes one plug 7 in one push. Since the untwisted pushing distance can be set to a predetermined length, the spout 1 can be accurately placed at a predetermined position on the transfer path 27. The operation of this pushing member 29 is as follows:
Normally, shuffling is started immediately and with an appropriate delay in accordance with the signal from the sensor 4, and after the pushing operation of the pushing member 29 is completed, the first spout γ on the spout alignment rail 24 is pushed from behind. It is automatically received into the transfer path 27 through the opening 26 and stopped at that position.

The spout conveying insertion member 23 and the transport path 2 of the spout supplying member 22
The spout 7 at a predetermined position in 7 is gripped by vacuum suction or the like, conveyed through the through hole 1 of the long film 1, and after being inserted into the through hole, the grip is released by releasing the suction force, etc. This also starts its operation in accordance with the signal from the sensor 4, and after the spout 7 is placed at a predetermined position on the spout supplying member 22 by the pushing member 29, it reaches that position and transports and inserts the spout. Do the following.

In this way, the long film 1 with the plug 7 inserted into the through hole is sent to the plug welding device section 30, and as shown in FIG. As a result, the base 72 of the spout 7 and the upper surface of the long film 1 (inner surface of the final packaging container) are thermally welded. The method of heat welding is
Although any other means may be used, it is particularly preferable to use ultrasonic waves because the pedestal 72 can be thermally welded efficiently without being thermally deformed.

In the spout welding device section 30, 32 is a heat-sealing base equipped with a recess into which the spout 7 can be fitted, and it rises a little for each seal to ensure sealing, and descends after sealing to attach the spout 7. 081 and 82 serve as guide a-rules to prevent the film from being pulled or wrinkled due to movement of the film, and a groove corresponding to the shape of the guide a-ru is bored at the position where the spout γ passes through. This transfer of the waste film is carried out smoothly.

9, a concave groove is provided along the running direction of the spout I attached to the long film 1 as a guide member for fine adjustment for introducing the spout I to a preferable position set in the next step. The installation position and length of the guide member 9 are appropriately designed as necessary.

The long film 1 that has passed through the guide member 9 and the guide roll 82 is then introduced into the vertical sealing device section 40. The vertical sealing device section 40 consists of a cylindrical guide member 41 coated with an anti-adhesive material such as polytetrafluoroethylene, and heat retaining members 42 and 43 disposed near the cylindrical guide member 41. In the cylindrical guide member 41, both side edges of the long film 1 are overlapped by a positioning mechanism in the shape of a gassho paste or an envelope paste, and the overlapped portion is fed 1 without wrinkles, and the overlapped portion is simultaneously The film is adjusted so that its position is accurately determined, and is heat-sealed by heat-sealing members 42 and 43 to form a cylindrical film 1'. In Figure 1,
An example is shown in which both side edges of the long film 1 are stacked so that the two sides of the long film 1 are stuck together in a state where the plug 7 is attached at a position shifted by 90 degrees from the overlapped portion. The heat sealing members 42 and 43 in this case are composed of a heating member 42 having a U-shaped cross section that heats the overlapped portion, and a pair of sealing press rolls 43 that press the heated overlapped portion.

When heat-sealing both side edges of the twisted long film 1 in an envelope-like manner, the cylindrical guide member 41 is used.
The seal receiver is used as a base, and the heat seal member 4 is constantly heated.
2 may be pressed against the film overlapping portion when the long film 1 is stopped.

Next, the cylindrical film 1' that has been vertically sealed is sent to a horizontal sealing process. Horizontal seal and film transfer device section 3fd,
It has a heat sealing function and sequentially performs horizontal sealing (lower sealing) while flattening the cylindrical film 1' at the gripping position and feeding it downward. In addition, in the direction of flattening the cylindrical film 1', it is desirable to select the spout 7 so that it is located at one side edge of the flattened cylindrical film 1'.

Reference numeral 50 denotes a filling device section for contents, and this filling device section 50
, 51 is a content delivery pipe for introducing liquid, viscous material, etc. into the bag, a metering pump is connected to the base end of the pipe, and the lower part is formed in the horizontal sealing process. Always add more contents at any point. Capacity regulating suppression plate 52 attached to the horizontal seal/film transfer device section 3.
52, the cylindrical film 1' containing the content is pressed from one side at a predetermined position, and a certain amount of the content is left below the cylindrical film 1', and the excess content is removed from the cylindrical film 1. In this state, an upper seal (which also serves as the next lower seal) is made, and the sheet is sent downward and cut at the horizontal seal portion by a cutter 60.

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 and the size ratio of the final package. You can also obtain something that looks like a normal laminate tube that is attached to the lengthwise end of the tube.

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 it possible to keep equipment costs relatively low. This can significantly improve manufacturing efficiency.

As is clear from the above description, according to the present invention, a film package with a stopper that allows the contents to be used economically in small quantities can be produced at a rate of 15 to 30 bags/min in a single row and 1 to 5 n in a n row. ~30
It has become possible to produce at a high speed of n bags/min, and in a fully automatic manner that greatly streamlines the traditional cottage industry work.
Furthermore, it is possible to prevent the unreliable supply of plugs, which tends to cause defects in this type of manufacturing equipment.
