Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology is used for soft packaging film sheets for snacks, etc.
It belongs to the field of film feeding technology when making and filling packaging bags for products that are sold in a packaged state.

Summary of the Purpose> Therefore, the invention of this application involves weighing products such as snacks at predetermined weights in a confectionery manufacturing factory, etc., and bagging them using paper, synthetic resin laminate film, etc. In the packaging process of filling and bagging, the starting end of the film sheet to be used subsequently is superimposed on the end of the used film sheet fed from the sheet roll used previously to the former of the packaging device, or A continuous connection method for packaging film sheets, in which the leading film sheet and the following film sheet are aligned and connected smoothly without any deviation in pattern or positioning using adhesive tape, and a device directly used in the method. This invention relates to the use of the end of a film sheet from a previously used sheet roll and the use of a film sheet from a subsequently used sheet roll when printing a certain pattern or mark on a film sheet wound onto a sheet roll. A predetermined cut mark is printed on the starting edge within an area narrower than one pitch of the bag, and the cross-cut is made in advance. Positioning it at the end of use indication mark and temporarily fixing it with a presser body such as a magnet, and positioning the use start end of the subsequent film sheet at the cut mark of the use start end and temporarily fixing it with a magnet etc. of the presser body, or , the end of use and the start of use are positioned at the same position, and an adhesive tape is applied to the overlapping or abutting part of the two to reduce the stop time of the packaging device to zero in automatic operation, or
When using manual work, keep it as short as possible to prevent a decline in work efficiency.
It is possible to stably and accurately continuously feed film sheets as designed, and if there is a tape adhesive part at the connection between the first used film sheet and the second used film sheet in the bag filled with the product. Continuous connection of packaging film sheets that allows the air inside the bag to escape through small holes or slits, etc., so that the bag can be easily found and removed reliably when packed into a cardboard box, etc. The invention relates to a method and an apparatus.

<Prior art> As is well known, as social life becomes more prosperous and citizens' lives become more affluent, a wide variety of products are traded in large quantities and in small quantities in the secondary market. In order to ensure smooth and stable distribution of these types of products, methods have been used in which the products are weighed and packaged in advance to a predetermined weight, etc., and in particular,
For products such as foods (including food ingredients), trading in packages such as bags in predetermined weights is not only convenient for the supply side, but also from the perspective of quality assurance. It has become widely popular among consumers because it is easy to use and has significant health and hygiene benefits.

Therefore, on the supply side in the distribution market, ready-made bags made of film made of two sheets of paper and a sheet of synthetic resin are laminated in advance to a predetermined size, and the bag is given a predetermined weight. In some cases, pre-weighed products such as snacks are filled into bags, but in order to reduce costs in the production process and ensure smooth and efficient packaging, film sheets are sent directly to the packaging machine. Automated packaging is widely used and established, in which bag-making is carried out by supplying goods, and products are also filled and packed into bags.

Therefore, in direct packaging using film sheets, combination laminates are used depending on the product to be filled, taking into consideration characteristics such as moisture resistance, permeability to gases such as oxygen, permeability to light such as ultraviolet rays, and impermeability. In addition, content display, photographs, advertisements, and other color printing are performed using film sheets processed by a specialized company called a converter.

The mode of such packaging work will be briefly explained with reference to FIG. 47. A film sheet of a predetermined width size is wound around a bobbin to form a film sheet roll 1, and a guide roller 2 for adjusting feed and a feed roller 2' are passed from the sheet roll 1 to a film sheet roll 1. (2'
The film sheet 11 is fed to the former 5 of the packaging machine 4 via a presser roller), a dancer roller 3 for absorbing slack, etc., and a cylindrical shape is passed along the outside of the cylinder 6 that integrally extends downward to the former 5. While forming the film, the film is intermittently pulled down and fed out by the film feeding device 7, the palm-shaped part of the edge is heat-sealed by the vertical sealer 8, and the horizontal sealer 8 below the edge is heat-sealed.
’ to seal the lower row horizontally, and remove the former 5.
Snacks and other products weighed to a predetermined weight by a pre-stage weighing device (not shown) are dropped into the cylinder 6 through an upper hopper 9 connected to the horizontal sealer 8.
' to simultaneously horizontally seal the upper part of the bagged pack 10 and the part that will form the bottom of the next bag, and cut the bagged pack 10 in a predetermined manner to form the bagged pack IO in a predetermined cycle. , For transverse cutting, etc., use film sheet 11.
Register marks 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 4, 5, 6, 5, 5, 5, 5, 5, 5, 2, 2, 2, 2, , , , , , registration marks are pre-printed for convenience of illustration.
Only one is shown. ), this is performed via a control device using a predetermined photoelectric detection device (not shown) (therefore, the distance between the pair of registration marks 12, 12 is set to be the length of one bag).

It should be noted that the film feeding device 7 performs intermittent feeding or is provided with a dancer roller 3 so that there is virtually no interruption in packaging.

Therefore, when it comes to automatic packaging, there are many cases where automatic packaging is carried out for long periods of time, for example, continuously day and night, in order to improve efficiency, increase operational efficiency, ensure stable supply in the secondary market, and reduce costs. Therefore, as shown in FIG. 47, the sheet roll 1, which is mounted and set on an arm (not shown), has a length of 1,000 meters (1,000 m) per unit, for example.
Even if it is made of a long film sheet with a length of 4,000 to 6,000 meters depending on the case, it is natural that if it is used continuously for a certain period of time (because of its finite length) When the end of use is reached, a sensor 7 such as a limit switch (not shown), which is installed near the end of use and close to the guide roll 2, detects the end terminal, and until then the next succeeding sheet roll is 1' is attached to the arm alternately, and the 49th (c),
(d) As shown in the figure, the used end 13 of the previously used film sheet 11 of the previously used sheet roll 1 is compared to the used starting end 14 of the film sheet 11' from the subsequent sheet roll 1'.
There is also a method of butt-connecting the
b) As shown in the figure, temporarily stop the packaging work and
3 and the starting end 14 for a predetermined length as short as possible,
In addition, printed advertisements, pictures, and other patterns were combined and pasted onto the surface using adhesive tape, and once this was completed, the packaging work was resumed and continued.

In this case, the connection portion using the adhesive tape 21 or the like is located between the registration marks 12 and 12 of the previously used film sheet 11 and the subsequently used film sheet 11', as shown in FIG. 50 (back side).

Therefore, prior use for bag making in the packaging process.

Film sheets for subsequent use 11.11' are so-called fin seals (gassho stickers) and overlap stickers (envelope stickers).
etc., but in any case, as mentioned above, there is a limit to the size of the sheet rolls 1, 1' in one unit, and the previously used sheet roll 1 and the subsequently used sheet roll 1
' Because of the continuous connection with
There is an overlapping part in the length direction of the later used film sheets 11 and 11', which are connected in place by the converter and delivered, but the earlier used film sheets 1 and 11' are overlapped before the packaging operation. Film sheet used 11'
The butting of the joints and the pasting with adhesive tape 21 etc. at the overlapping parts must be done by the user (packaging company), and this is not the conventional manual pasting. Also, if the printing patterns such as advertising phrases, instructions for use, and patterns printed in advance on the first used film sheet 11 and the second used film sheet 11' are misaligned or misaligned, pitch deviations will occur for each bag, and the If the capacity of the automatic pitch alignment device installed in the packaging machine is exceeded, problems will continue to occur until the pitch is corrected. It was also practiced to restart the packaging machine after doing it correctly.

And film sheet 11. The inner product storage area of the bagged Mepack 10 by +1' has no advertising effect, and printing is not done from the viewpoint of hygiene and to prevent deterioration due to solvents such as ink during printing, odor, etc. Furthermore, if printed on the surface, it may be damaged depending on the degree of contact with other objects, so direct printing on the surface is avoided, and printing is done in the middle of the laminate near the surface. The subsequent use film sheet Ml' is pasted onto the previously used film sheet 11 using the adhesive tape 21 or the like in an autoclave manner, in order to feed it into the bag making and filling section of the packaging machine, so that it is attached to the rear side when viewed from the rear of the packaging machine. When viewed from the back side, the adhesive must be oriented so that the back side is visible, not the front side of the printing side. Therefore, even with a film sheet like the one described above where printing is done only on the front side and not on the back side, it is difficult to bond the adhesive. Even if the entire surface of the film sheet is printed, if it is a transparent film-based packaging material, the front side can be seen from the back side.
Since it was possible to match patterns such as pattern matching, pattern matching, and positioning with the used starting edge 14 of ′ on the printing side, it was possible to do so without having to perform pattern matching on the printing side. The continuous connection between the end of use 13 and the start of use 14 of the later used film seam M+' is generally carried out without any problem.

<Problems to be Solved by the Invention> However, in such a conventional embodiment, the starting end 14 of the later used film sheet 11' is attached to the end 13 of the previously used film sheet 11 using an adhesive tape 21 or the like. Whether the connection is done manually or automatically using a designated device, packaging work must be done in order to ensure that there is no misalignment of the front and back connections or patterns, and that the pitch of each bag is adjusted and the packaging work is carried out accurately as designed. It is necessary to pause, interrupt, and perform the work in a stopped state. Therefore, the interruption leads to a decrease in work efficiency. Therefore, it is important to shorten the interruption time, that is, the stopping time as much as possible, to improve the efficiency of the overall packaging work. This has become a decisive factor in increasing productivity, and conventional manual methods have the drawback of being inefficient and requiring extremely high skill.
In addition, if you try to do this automatically, the structure of the device will become extremely complicated due to the use of an automatic pitch adjustment device, maintenance control device, etc., and maintenance such as inspection and maintenance will be extremely troublesome. The disadvantage was that it affected the cost.

In recent years, there has been a demand for good seating of packaged bags when displaying products at two end-of-market stores, etc., as well as rancidity, putrefaction, mold growth, deterioration, and even moisture absorption of the filled products. In order to prevent complaints, etc., laminate films such as aluminum vapor-deposited films with high light-shielding and gas barrier properties are now used for bag-making films, but advertising and display items are still printed on the front side. If the laminated film is transparent as mentioned above, it will be visible from the back, but aluminum vapor deposition or
When laminated with paper, that part is opaque and cannot be seen from the back side to the front side. Therefore, when the previously used sheet roll 1 is finished being used, there is no possibility that the paper will be separated from the previously used sheet roll 1' and the later used sheet roll 1'. Used film sheet u, tt
The pasting through the adhesive tape 21, etc. at the butt part 9 of the overlapping part between the end of use 13 and the start of use 14 is done during work, when both are seen through from the back side to match the design pattern etc. and position. A problem arises in that it is not possible to perform alignment work such as, etc., making it impossible to continue the work, and as a result, the end of use 13 of the previously used film sheet 11 and the beginning of use 14 of the subsequently used film sheet 11' are connected by pasting. It is said that it is difficult to shorten the packaging work for this purpose, which may lead to a decrease in efficiency. There was an inconvenience.

Further, as mentioned above, the connection part between the end of use 13 of the previously used film sheet 11 and the start of use 14 of the subsequently used film sheet 11' by the adhesive tape 21 etc. is the registration mark 1.
Since it is located between 2.12 and 12, as shown in FIG. 51, in automatic packaging etc., products are originally placed in that area and filled.

Therefore, it is shipped as it is and placed in a pack of 1 on store display shelves.
If a 0 is arranged, the connection is ignored and, in some cases,
There is a risk that it will appear as if the adhesive tape 21 has been peeled off and the product inside has been tampered with and the adhesive tape 21 has been reattached.

To deal with this, in automatic packaging systems, if the adhesive part is located approximately in the center of the pack 10, an electrical interlock is installed to prevent the product from being inserted or filled, or in older types of equipment, the May be filled.

Therefore, in order to avoid such an unexpected situation, if the adhesive tape 21 or the like is located approximately in the center of the pack 10, the adhesive tape 21 is made into a colored tape so that it can be easily discovered so that it can be removed during packing or the like. Even if it is possible to detect whether the product is being packed by hand, there is a problem in automatic packaging in which the sensor cannot distinguish the color, and using a color-distinguishable sensor has the disadvantage of significantly increasing costs.

<Object of the Invention> The object of the invention of this application is to detect the end of use of a film sheet from a previously used sheet roll and the beginning of use of a film sheet from a subsequently used sheet roll during continuous packaging of snack products, etc. based on the above-mentioned prior art. Problems such as butting or overlapping connections of a predetermined length, adhesive parts in bag making, etc., are considered technical issues to be solved, and it is possible to accurately connect previously used film sheets as designed without requiring the same level of skill. After-use film sheets can be butted together or overlapped and attached using adhesive tape, etc., easily by hand or automatically, and there will be no misalignment or misalignment of the pattern, etc.
Packaging in the distribution industry by ensuring continuous supply of film sheets to the bagging process in the bag making process, and in cases where the bag has an adhesive part, ensuring that the bag can be removed. It is an object of the present invention to provide an excellent method for continuously connecting sheets of packaging film that will benefit the field of technical application, and an apparatus for direct use in the method.

<Means/effects for solving the problem> In order to solve the above-mentioned problem, the structure of the invention of this application, which is based on the above-mentioned claims, is to display the product name, specifications, advertising matters, etc. on the front side. When making bags and filling products with opaque film sheets such as laminates that are printed in a specified manner and coated with aluminium, first, the sheet rolls to be used earlier are set on the arm, and the sheet rolls from the sheet rolls that are used earlier are loaded. The film sheet is fed to a former of an automatic packaging device via guide rollers, dancer rollers, etc., and formed into a circular cross-section along the outside of a cylinder provided integrally with the former to form a film feeding device. The cylinder is intermittently pulled down, and vertical seals are performed on the opposing edges, and a lower horizontal seal is performed at the bottom of the cylinder. The weighed products are dropped and filled, and the upper stage is again horizontally sealed and the bottom of the next bag to be filled is simultaneously horizontally sealed, and the middle is cut horizontally with a cutter to fill the bag. These cycle operations are controlled by photoelectric detection of registration marks pre-printed on the edge of the film sheet, and cut marks are pre-printed on the edge of the film sheet to prevent previous use. The end of the used film sheet and the starting end of the later used film sheet are cut in advance smoothly in the horizontal direction.
When the film sheet of the previously used sheet roll approaches the end, the next sheet roll to be used is mounted and set on the arm, and when the previously used film sheet is finished,
The end of use is detected by a sensor, the packaging machine is automatically stopped, the end is temporarily fixed with a presser such as a magnet in alignment with the end of use indication mark previously formed on the plate-shaped crimp body, and then , the starting end of the later used film sheet from the later used sheet roll is also aligned with the starting end indication mark provided in advance on the crimping body (in the butt mode, both indication marks coincide), and the previously used film sheet is rolled. Temporarily fasten with a presser such as a magnet when the ends are brought together or overlapped, and adhesive tape etc. is applied so that the end of use and the beginning of use of both film sheets are butt or overlapped. The packaging device is restarted by connecting the previously used film sheet and the subsequently used film sheet, and during automatic connection, the starting end of the subsequently used film sheet is held by a crimping body that can be opened and closed. By temporarily fixing the product to the body using a temporary fixing device such as a vacuum device, at that time pasting approximately half the width of the adhesive tape used for connection, and then overlapping the film sheet holder on the crimped body and closing it. An adhesive tape is used to attach the starting end of the later used film sheet to the used ending end of the previously used film sheet, and both film sheets are connected. An instruction mark is provided for the starting end of use, and a presser is attached to the film sheet holder, so that when the end of use of the film sheet from the previously used sheet roll approaches, the later used sheet roll is loaded. Then pull out the starting end of the film sheet and temporarily fasten it with a temporary fastening device such as a magnet along the starting end of the film sheet holder. Attach the adhesive tape to the film sheet holder and press the presser body against the film sheet holder to overlap the used end of the previously used film sheet and the used end of the subsequently used film sheet against the adhesive tape. The sections are automatically pasted together, and the later used sheet rolls are alternately transferred to the earlier used sheet rolls. It is made to ensure that there are no pictures or misalignment of the designs or marks on the film sheets used after use, and that the film sheets are connected continuously without interruption during continuous operation. In the case where adhesive tape is present in the center part, a small air vent hole or slit is formed near at least one of the end of use of the previously used film sheet and the beginning of use of the subsequently used film sheet. Then, when packing the bag into a cardboard box or the like, the air inside the bag is released and it is immediately obvious that there is an adhesive tape section in the bag, so a technical measure has been taken to make it possible to remove this bag.

<Example> Next, an example of the invention of this application is described in No. 45.46゜48 (
The following description will be made with reference to FIGS. 1 to 46, with reference to FIGS.

It is a bar-shaped magnet with a predetermined size and a rectangular cross section that temporarily fixes the film sheet 11, 11' in close contact with the pressure bonding body 17.

And 21 is a single-sided adhesive tape.

In the above configuration, similarly to the general embodiment shown in FIG. 47, the initial used sheet roll l is mounted and set on an arm (not shown) via the pivot of the bobbin, and the aluminum vapor-deposited laminate type previously used film sheet 11 is fed out. , guide roller 2. The film is fed through the dancer roller 3 to the former 5 of the packaging machine 4, formed into a circular cross section on the outside of a cylinder 6 provided integrally therewith, and is intermittently fed at a predetermined speed by the film feeding device 7. The opposite edges are vertically sealed with a vertical sealer 8, the lower horizontal seal is applied with a horizontal sealer 8', and the upper hopper 9 connected to the cylinder 6 is connected to the cylinder 6. Products such as snacks that have been weighed to a predetermined amount by the previous weighing device are put in, and the horizontal sealer 8' simultaneously seals the top of the bag and the bottom of the next bag at the same time. A cutter (not shown) cuts the middle, and bags 10 filled with products are continuously formed at a predetermined pitch.

The horizontal sealer 8' and the like are controlled in a predetermined manner by detecting the registration mark 12 by a photoelectric detection device (not shown).

The mode up to that point is no different from the general conventional mode.

As bag making, filling, and packaging are carried out continuously, the previously used film sheet 11 from the previously used sheet roll l is
When the end of use 13 is detected in a predetermined manner by a detection device such as a limit switch (not shown), the packaging machine 4 is stopped and the later used sheet roll 1' is moved to the upper part of the roll position of the previously used sheet roll l according to a predetermined program. The arm is replenishingly set in advance and kept on standby, and at this time, the previously used film sheet 1 from the previously used sheet roll 1
As for the use end 13 of No. 1, the use end 17 is cut by hand according to the cut mark 16 previously formed on the previously used film sheet 11, as shown in FIGS. 2 and 3. positioning and setting to coincide along the line between the indicator marks 18.18, and
As shown in FIG. 4, the bar-shaped magnet 20 temporarily adheres and attaches the crimping body 17.

When transferring ' to the lower arm 38', you can freely drive the movable roll 36'36' so as not to hinder the feeding of the film sheet 11', and also attach the upper arm 38'. Various embodiments can be adopted, such as using the trolley for preparing the film sheet for adhesion or for transferring it to the lower arm 38'' depending on the timing.

Furthermore, it goes without saying that the target film sheet is not limited to an aluminum vapor-deposited film sheet, but may also be a paper sheet, a mesh sheet, or even a type of film sheet that is printed on a transparent base film.

<Effects of the Invention> As described above, according to the invention of this application, a previously used film sheet from a previously used film sheet roll is basically used in product filling packaging following the manufacturing of pillow-type bags using aluminum vapor-deposited film sheets, etc. When connecting the starting end of a post-use film sheet from a post-use film sheet roll to the end of the post-use film sheet roll in an integral continuous manner by pasting adhesive tape, or when temporarily interrupting the packaging operation to connect both film sheets. Even if the film sheet cannot be seen through from the inside, it must be cut and formed in advance according to regulations that set the start and end points of use according to the cut marks provided on the edges of the film sheet. Roll it up, and temporarily fasten the starting and ending edges of the product using a temporary fixing device such as a magnet so that it matches the instruction mark on the crimping body or film sheet holder, and then attach it with adhesive tape. By simply attaching the film sheet, the previously used film sheet and the subsequently used film sheet can be continuously connected to each other and continuously supplied to the continuous former without having to look at the printed surfaces and match the patterns. This makes it possible to significantly shorten the time required for packaging interruptions even when done manually, and by doing it automatically, it is extremely easy to wrap products continuously without stopping the packaging machine. It is possible to prevent a decrease in packaging operating efficiency, and to improve work efficiency, which is an excellent effect.

In addition, since it is only necessary to position the end of the previously used film sheet and the starting end of the subsequently used film sheet with respect to the instruction marks on the crimping body and the film sheet holder, the work does not require the same level of skill and can be easily performed. This can be done easily and has the effect of not causing a decrease in work efficiency.

In addition, even if adhesive tape is attached to an aluminum vapor-deposited laminated film sheet, etc., where it is difficult or impossible to see through from the back side, the start of use can be made at the predetermined cut mark position printed on the film. It is assumed that the end of use is processed, but the end of use of the previously used film sheet and the beginning of use of the subsequently used film sheet are printed on the front side so that they match the instruction marks on the crimping body and film sheet holder. This has the effect of preventing picture displacement or misalignment of the pictures, content marks, etc. of advertisements, even if done from the back side, which cannot be seen through.

Furthermore, according to the method of the invention of this application, since the pitch of the Fukuroi method is maintained correctly, there is almost no need to make corrections using the automatic pitch adjustment device built into the packaging machine, and the conventional method of gluing can This eliminates the occurrence of non-negligible defective bags that would otherwise occur during the correction operation due to insufficient pitch alignment, and therefore eliminates the need to remove them, thereby eliminating the need to impair consumer confidence.

Generally, it is easy to bond the end of the previously used film sheet and the starting end of the subsequently used film sheet by slightly overlapping the film sheets, but in this case, the gluing operation requires precision. It is fully possible to perform the butt-type adhesion automatically, and the excellent effect that extremely accurate packaging and bag-making operations can be achieved is achieved by printing cut marks on the film sheet at one location.

In addition, by forming a small air vent hole or slit in at least one of the end of the used film sheet and the beginning of the used film sheet, it can be connected to the bag part during bag making. Even with the adhesive tape attached to the bag, air can be released from the inside of the bag when packaging it in a cardboard box or the like, making it easier to find and remove the bag.
