Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for attaching an adhesive tape having a folded portion to an object to which the tape is attached, and an apparatus used in this method. More specifically, the present invention provides an adhesive tape having a folded part to facilitate the detection and removal of the film end of a film-wound layer, or the opening of a package hermetically sealed with a resin film. The present invention relates to a method for continuously and efficiently attaching tape and an apparatus for carrying out the method.

2. Description of the Related Art Conventionally, FR. Resin wrap film is usually sold as a roll wound around a core material, and when using it, the consumer must find the end of the 7-film roll and peel it off. However, in view of suitability for packaging applications, these films inherently have extremely good adhesion and are thin and transparent, making it difficult to identify or peel off the edges of the film.

As a means to solve this problem, a film roll attached with an adhesive tape having a structure shown in the perspective view of FIG. 2 and the sectional view of FIG. 19674).

This film roll has a film winding layer 2 having an end portion 3 wound around a winding core l, an adhesive tape 4 is applied in the same winding direction as the winding of the film on the outer periphery of the roll, and starting from one circumference of the roll with 5 as the winding start end. It has a structure in which the tape is wound slightly longer and a folded part 6 is provided at the terminal end 6' of the tape winding so that the adhesive surfaces are bonded to each other. In this way, by attaching the adhesive tape 4 provided with the folded portion 6, the end portion 3 of the film, which has an extremely thin wall thickness, high transparency, and extremely high adhesion, can be easily removed during use. was discovered, and the film was removed from that area,
It is easy to take out and use. For example, if you grab the end 6' of the tape winding and peel off the adhesive tape 4,
Since the adhesive tape 4 is attached to cover more than one circumference around the cylindrical circumference of the wrapped film layer 2, the winding end portion 3 of the film is always peeled off and the film is unwound.

At this time, the roles of the folded part 6 provided at the end 6' of the tape winding are: (1) to prevent the tape from sticking to other objects with the adhesive surface of the end 6' of the adhesive tape winding; (2) at the end of the winding of the adhesive tape; (3) It saves the trouble of attaching a new one. Therefore, there are various possible applications for which the adhesive tape having the folded portion can be attached and utilized, such as marking classification, application, and application for providing easy-to-open properties of packages.

A method of producing a wrapped film layered body equipped with such an adhesive tape having a folded portion using an apparatus shown in the explanatory diagram of FIG. 4 is known (Japanese Utility Model Publication No. 19676/1983). In this method,
While the wrapped film layer 2 moves in an arcuate trajectory from position a to position b while rotating in the direction of arrow C,
Adhesive tape 4 is wound and adhered to a predetermined length. When the predetermined length of the adhesive tape 4 is wrapped, the dancer roll rises and the cutter mechanism 7 rotates in the direction of the arrow d, so that the adhesive tape 4 is wrapped around the next wrapped film layer 2.
are in contact with each other, and the wrapped film layer 2 at position b
The end of the adhesive tape 4 attached to the cutter blade 7
′ is cut by the tension at the tip. The terminal end thereof is held by the suction part 9, and the end part of the adhesive tape 4 is bent by the air jetted from the air nozzle 8 and the rotation of the suction part 9 in the direction of the arrow d, and the adhesive surfaces are pasted together. death,
Due to the rotation C of the rolled layered body 2 in the direction of arrow C at position b, the adhesive tape 4 is further wound up and pasted, and the adhesive tape having the folded part shown in FIGS. 2 and 3 is attached. A film roll is obtained.

However, in methods using such devices, (1) wrinkles tend to occur in the film on the side of the adhesive tape due to shrinkage of the adhesive tape that is stretched by tension during wrapping; (2)
The adhesion positions of the adhesive surfaces are different from each other, which deteriorates the appearance of the folded part 6, and there is a risk that the tape may stick to other objects with the different adhesive surfaces. (3) Incomplete cutting of the adhesive tape occurs. However, there is a problem in that defects such as products being connected to each other at uncut portions of the adhesive tape are likely to occur.

The occurrence of such defective phenomena tends to increase as the output of products per unit time increases, and especially when defective phenomena (1) and (2) above occur, the value of the product will be significantly reduced. In addition, since it is not easy to detect that the failure phenomenon described in (3) is not disconnected (connected), it will continue to flow through the process as it is, and it will flow down individually. destroy the adjustment mechanism and adjustment device of a certain process based on the premise that
This causes a major disruption to systemized continuous processes, and the economic and time losses required for repair and restoration are extremely large.

As described above, with the conventional technology, it is impossible to efficiently attach an adhesive tape with a folded portion to an object to be attached without causing the above-mentioned defective phenomenon, and an improvement has been strongly desired. .

Problems to be Solved by the Invention Under these circumstances, the present invention solves the problem of a significant decrease in commercial value of an adhesive tape having a folded part on the object to be attached.
The purpose of this invention is to provide a method and device for efficiently attaching products without causing any defects and without causing uncut adhesive tape parts to become connected to each other. It is something.

3. To provide an adhesive tape mounting device having a folded portion that is free from the above.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view of an example of an apparatus of the present invention for attaching an adhesive tape having a folded part to a wrapped film roll for detecting and taking out the end of the film, and FIG. 1 and 5 are side views of an example of the apparatus of the present invention for attaching an adhesive tape having a folded part as an easy-opening means to a package sealed with 7-ilm resin; FIGS. In , the tape-attached object 2 is shown as a wrap film roll 2 and a packaging film 2, respectively, and the transport mechanism 13 is shown as a roll transport mechanism 13 and a film transport mechanism 13, respectively. The rotating bodies 12 are each illustrated as a cylindrical rotating drum 12, but they may also have a polygonal cross section, and the rotation of the folded cup 17 depends on the reversal of gravity and the guide plate 2l. The cam 4! ! ! ! It is also possible to adopt a structure in which the reversal rotation is performed by a structure and the return rotation is performed by an elastic spring.

Regarding the positional relationship of the adhesive tape supply device 11, the adhesive tape cutting means 7, and the transfer mechanism 13, both FIG. 1 and FIG. The location of the main body can be selected relatively freely, and although four folded cups 17 are each provided on the rotating body 12, there is no particular restriction on the number.
It is appropriately selected depending on the length of the adhesive tape, the diameter of the rotating body, and the desired speed of the device. Furthermore, although the elevating mechanism 14 is illustrated as the reciprocating mechanism 14, the operating direction thereof is as follows.
It is determined by the positional relationship between the rotating body 12 and the transfer mechanism 13.

As described above, FIG. 1 and FIG. 5 each show an example of the device of the present invention, and the device of the present invention is not limited thereto.

Next, the method of the present invention carried out using the apparatus shown in FIG. 1 will be described. The adhesive tape 4 drawn out from the adhesive tape supply mechanism 11 is passed through the guiding means 15 with a small tension, that is, with a tension that prevents the adhesive tape from stretching. It is sent to the outer circumferential surface of the rotating body (rotating drum) 12 via. It is preferable that the circumference of the rotating body 12 is shaped to be an integral number of the cutting length of the adhesive tape. A large number of suction holes 16 are provided on the surface of this rotating body 12, and by reducing the pressure inside the rotating body,
The adhesive tape 4 can be temporarily held by suction on its surface. The adhesive tape 4 held on the outer peripheral surface of the rotating body 12 with the adhesive surface facing outward is cut along the wall surface 20 of the rotating body recess 19 by the adhesive tape cutting means 7 equipped with a blade 7'. By reciprocating, it is cut into a predetermined length and moves downward as the rotating body 12 rotates. During this movement, the recess 1 of the rotating body 12
The folded cup l7 housed in the rotor 9 rotates around the rotation shaft 18 by its own weight in the rotational direction of the rotating body 12 and reverses itself. At this time, the end portion of the adhesive tape 4 on the folded cup l7 is folded back to the adhesive side and pasted together with the adhesive surfaces, forming a folded part 6 (see Figs. 2 and 3). . As the rotating body 12 rotates, the inverted folding cup 17 (not shown) is pressed by touching the guide plate 2l provided adjacent to the rotating body 12.
It is returned and accommodated in the original recess 19 of No. 2.

On the other hand, directly below this rotating body 12, there is an object to which the tape is attached (
The wrapped film (wound layer) 2 is sequentially fed by a transfer mechanism (wound layer transfer mechanism) 13, and at a position directly below the rotating body 12, the reciprocating mechanism (elevating mechanism) 14 moves the winding shaft of the wrap film to the rotating body 12. The rotating body 12 is placed almost parallel to the rotation axis.
is pushed up toward the outer periphery. At this time, the adhesive tape 4, which is suction-held with the folded end 6 on the outer circumferential surface of the rotating body 12, has been rotationally moved to the lower side of the rotating body 12, so that the adhesive tape 4, which is being pushed up, is attached to the tape target. It comes into contact with the wound end of the object (wrap film roll) 2 at a substantially central portion thereof, and is transferred and mounted around the roll that rotates in the opposite direction to the rotating body 12 . In this case, if necessary, the suction can be canceled or reduced in order to facilitate the removal of the adhesive tape 4. The tape-attached object (wrapped film layer) 2 that has been transferred and attached is returned to the normal transfer position by the reciprocating mechanism (elevating mechanism) 14, and then transferred to the transfer mechanism 13.
It is transported and carried out by.

According to the technique of the present invention, the adhesive tape 4 cut to a predetermined length is temporarily held on the outer circumferential surface of the rotating body (rotating drum) 12, and the tape-attached object (wrapping Film winding end portion 3 of film winding layered body) 2
while rotating the rotating body 12.
In order to affix the adhesive tape 4 in the circumferential direction of the object to be taped (wrapped film layered body) 2, the adhesive tape that has been cut securely is transferred from the rotating body 12 to the object to be taped (wrapped film layered body). ) 21 is transferred and attached, and there was a problem in the past because the individual pieces of the tape-attached object (lamp film wound layer) were connected by incompletely cut adhesive tape parts, which caused problems with subsequent packaging. It is possible to completely eliminate a series of troubles that would confuse the process. In addition, since the elongation in the length direction due to the tension that tends to remain in the adhesive tape is completely alleviated, wrinkles do not occur on the sides of the adhesive tape, and the bonding position of the adhesive tape folded part 6 is Since there will be no discrepancy, the product value as a wrap film will not be reduced.

Next, to explain the method of the present invention carried out using the apparatus shown in FIG. 5, the adhesive tape 4 drawn out from the adhesive tape feeder @ 11 is guided by a guiding means with a small tension, that is, a tension that does not cause the adhesive tape to stretch. It is sent to the outer circumferential surface of the rotating body (rotating drum) 12 via the rotary drum 15 . This rotating body 12
The circumference of the adhesive tape is preferably formed to be an integral multiple of the cutting length of the adhesive tape. A large number of suction holes 16 are provided on the surface of the rotating body 12, and by reducing the pressure inside the rotating body, the adhesive tape 4 can be temporarily held on the surface by suction. The adhesive tape 4 held on the outer circumferential surface of the rotating body 12 with the adhesive surface facing outward includes a blade 7';
The adhesive tape cutting means 7 reciprocates the blade 7' along the wall surface 20 of the rotary body recess 19 to cut the adhesive tape into a predetermined length, and moves downward as the rotary body 12 rotates. During this movement, the folded cassop 17 housed in the recess 19 of the rotating body 12 rotates in the rotational direction of the rotating body 12 around the rotating shaft 18 due to its own weight and is reversed. .

At this time, the end portion of the adhesive tape 4 on the folded cup 17 is folded back to the adhesive side and pasted together with the adhesive surfaces to form a folded part 6 (see FIGS. 2 and 3). The folded cup 17 (not shown) which is inverted as shown in FIG.
2 rotates, it is pressed by touching the guide plate 2l provided close to it, and the original concave portion 1 of the rotating body 12 is
It is returned and stored within 9.

Such a reversal and return storage method of the folding cup l7 is as follows.
In addition to the method shown here, it is also possible to use, for example, a combination method of reversing using a cam mechanism provided on the rotating body and returning and storing using a spring.

The combination of this cam mechanism and spring is based on the rotating body 1.
If a high rotational speed of 2 is desired, it is advantageous because reliable operation can be achieved without damaging the device (this also applies to the device of FIG. 1).

On the other hand, on the lower side of the rotary body (rotating drum) 12, the tape-attached object (wrapping film) 2 and the wrapped object 23 supplied from the original film 22 are connected to the transfer mechanism (7 film transfer mechanism) 13. The packaged items are sequentially sent by the packaged item transfer device 24. The tape-attached object (packaging film) 2 is intermittently made with a scratching device 25 for each package by making small cuts (for example, U-shaped scratch holes) 31 corresponding to the l@ locations. It is guided directly below and further pushed up by the reciprocating mechanism (elevating mechanism) 14 so as to come into contact with the outer circumferential surface of the rotating body 12 . At this time, the adhesive tape 4, which is suctioned and held with the folded portion 6 on the outer peripheral surface of the rotary body 12, is rotatingly moved to the lower side of the rotary body 12, so that the object to which the tape is attached is pushed up. (Packaging film) 2 is transferred so as to be aligned with the position where the small cut 3l is covered by the tape portion near the folded portion, which is approximately at the center of the packaging film.

This synchronization is performed by adjusting the time lag between the operation of the wounding device 25 and the operation of the reciprocating mechanism 14.

In the transfer, the adhesive tape 4 on the outer circumferential surface of the rotating body 12 is transferred onto the tape-attached object (packaging film) 2 by the contact pressure between the rotating body 12 and the pressure roll 26 that rotates in the opposite direction. In this way, the adhesive tape 4 is linearly extended on the film.

Next, in this way, the object to be tagged (packaging film) 2 covered with the adhesive tape 4 whose small cut 3l has a folded part 6 is placed so that its both side edges overlap at the lower part of the folding 27. The overlapping part of the bottom is sealed with a sealer 28 while the package is folded into a cylindrical shape with the object 24 inside, and the tip of the package is further cut and sealed with a cutting sealer 29 to seal the package tightly with a film. A package 30 covered with is obtained. This package 30 can also be made into a package covered with a tight film by passing it through a heating furnace (not shown) and heat-shrinking the extra film, if necessary.

As described above, according to the technique of the present invention, the adhesive tape 4 cut into a predetermined length is temporarily held on the outer peripheral surface of the rotating body (rotating drum) 12, and the tape-attached object ( The adhesive tape 4 is supplied to a predetermined portion of the packaging film (packaging film) 2, and without rotating the rotating body 12, the adhesive tape 4 is transferred in the longitudinal direction of the tape-attached object (packaging film) 2.
In order to attach the adhesive tape 4, the adhesive tape 4 that has been cut securely is placed on the film. Since they are connected by the adhesive tape, there is no problem of the packaging film being pulled together and causing confusion in the subsequent packaging process. In addition, since the elongation in the length direction due to tension that tends to remain in the adhesive tape is completely alleviated, there is no possibility of film wrinkles occurring on the sides of the adhesive tape, and furthermore, the bonding position of the adhesive tape folded part 6 can be adjusted. Since there is no discrepancy, the commercial value of the package will not be reduced.

FIG. 6 is a perspective view showing an example of an easy-to-open film package produced by the method described above using the apparatus shown in FIG. 5, and FIG. 7 is a partial perspective view showing the state in which it is used. be.

In FIGS. 6 and 7, the packaging body 30 includes a packaging film 2 that covers the outer surface of a box-like packaged object 2l, a seal line 32 between the films, and a central portion of the top surface of the packaging body. This is an easy-to-open film package having an easy-to-open part Z arranged on the film surface of the package. The feature of the present invention in this package is that the easy-opening part Z has one small cut 3l punching through the film surface, this small cut 3l is covered with an adhesive tape part near the folded part 6, and It has a structure consisting of a combination with an adhesive film 4 which is attached to extend in a linear manner.

In this package, when the folded portion 6 is gripped and the adhesive tape 4 is pulled in the direction of the tape extending, the tearing of the film from the small cut 3l proceeds along the side edge of the adhesive tape 4. , an opening having a length substantially equal to the length of the attached adhesive tape 4 can be reliably formed there. Therefore, the easy-to-open film package of the present invention can be used as a box-shaped film package, a general tray package, or an iron head, which is difficult to open because the film is in close contact with the packaged object.
It is particularly effective when applied to packaging for bread, bizzare pies, etc.

Effects of the Invention According to the present invention, even in a high-capacity operation in which 50 products per minute are produced with adhesive tapes having folded parts, the incidence of defective products that occur in, for example, 10,000 products can be reduced. is about less than (Cl%).

Therefore, the technology of the present invention is extremely suitable for industrial production. Conventionally, the greatest obstacle to improving production capacity was the frequent occurrence of defective products in the process of attaching adhesive tapes with folded parts. It is extremely useful as a means of increasing the production capacity of film packaging bodies or as a means of making film packaging bodies easy to open.

Furthermore, by using this technique, an easily openable film package to which the adhesive tape with folded portions of the present invention is attached can be manufactured extremely efficiently. The easy-to-open film package has, for example, a flat surface that is wide enough to attach an adhesive tape or a surface that can be wrapped with a 7 film attached with an adhesive tape, and has an adhesive strength that allows the adhesive tape to be peeled off. On the other hand, it can be applied to film packaging where the tear propagation strength of the film propagated from small cuts is small, so it can be used for film packaging for boxes such as gyoza and shumai, general tray packaging, and film packaging for bizabai and manju. It can be suitably used for packaging a wide range of items.

Example Next, the present invention will be explained in more detail with reference to Examples.

Example 1 Saran wrap [trade name, manufactured by Asahi Kabo Kogyo Co., Ltd., vinylidene chloride resin film, thickness approximately 10 pm, width 30011
1111, winding length 20++! ] The method of the present invention was carried out using the apparatus shown in FIG. The target shape is shown in Figures 2 and 3, and the adhesive tape 4 has a width of 9 mm.
, a commercially available cellophane adhesive tape with a thickness of 20p++1 was used, the tape length was set to 150+nm, the folded part 6 was set to a 20mm dimension target, and the supply speed of the wrapped film layer 2 was set to 3.
Experiments were conducted in which 10,000 bodies were produced at 0 bodies/l minute and 50 bodies/l minute, respectively.

For each of the 10,000 specimens thus obtained, the number of defective products represented by A, B, and C below was investigated. The results are shown in the table.

A: Defective product with tape cutting B: Defective product with discrepancy in the pasting position of the folded part C: Defective product with twitching and wrinkles on the sides of the tape (Note that some of these defective products may be counted as defective products twice) Comparison EXAMPLES Example 1 was carried out in the same manner as in Example 1, except that the adhesive tape 4 was attached using the apparatus shown in FIG. 4, and the number of defective products was investigated.

The results are shown in the table.

From this table, it can be seen that the technology of the present invention is an excellent technology that is less likely to produce defective products. In particular, the fact that there are no defective products even when the feeding speed is increased to 50 pieces per minute means that conventional adhesive tapes with folded parts could not be attached efficiently, and productivity could not be improved by increasing the speed. It can be seen that the present invention is an extremely useful technique for film production.

Example 2 Using the apparatus shown in FIG. 5, a box-shaped, easy-to-open film package shown in FIGS. 6 and 7 was produced.

Length 200mj+, width 100m+I1 including shumai
, A box with a height of 30 mm is used as the packaged object 23, and the packaging film 2 is a commercially available cross-linked polyethylene stretched film with a thickness of 15 μm. In addition, the adhesive tape 4 has a width of 9 so that
Using a commercially available cellophane adhesive tape having a thickness of 20 mm and a length of 150 mm, the test was carried out so that a folded portion 6 of 20 mm length was formed.

An experiment was conducted in which 10,000 packages were produced at a feeding rate of 70 packages/min, and the number of defective products was determined in the same manner as in Example 1, and ease of opening was also examined.

As a result, the number of defective products A, B, and C was zero, and all products were easy to open. From this, it can be seen that the technique of the present invention is extremely useful as a means for imparting easy-openability in film packaging of items to be packaged that have a surface portion that can be wrapped with a film attached with an adhesive tape.
