Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a conveyor belt film that is attached to a handrail surface of a belt conveyor such as an escalator or a moving sidewalk in a building or a station building and displays various information such as advertisements.
[0002]
[Prior art]
The handrail surface of the belt conveyor called an escalator or moving sidewalk plays an important role in ensuring the safety of the user, but on the other hand, dirt adheres to the user so that the dirt is left as it is. Since it is unsanitary and unsightly, it is necessary to always clean and keep the handrail surface of the belt clean.
[0003]
Such dirt on the handrail surface is often cleaned by mechanical work, but the handrail surface of the belt is only temporarily cleaned, and after a while, strong dirt adheres again. As a result, troublesome and time-consuming cleaning work has to be carried out regularly, and much labor has been spent on the cleaning work.
[0004]
Further, since the belt is deformed and the aesthetic appearance is lost by frequently performing such cleaning work, the belt needs to be replaced, and the maintenance cost for that is increased.
[0005]
On the other hand, by attaching a protective film to the handrail surface of the belt, troublesome cleaning work is unnecessary, and hygienic use is possible by simple wiping, and information such as advertisements and guidance is displayed on the handrail surface of the belt. A convex belt film that can be displayed above is provided (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, a conventional film for a belt conveyor uses a film in which films of the same quality and the same thickness are laminated. For this reason, when the belt is attached to the handrail surface, if the film is mechanically pressed against the handrail surface during the sticking operation, the printed film will be distorted and the advertising display such as marks will be deformed. There was a problem that.
In addition, since the entire film is elongated and flexible, a part of the film hangs down when the belt is attached to the handrail surface, and a part of the adhesive layer of the belt other than the handrail surface of the belt or the handrail surface of the belt. There was a problem that some parts were inadvertently touched and stuck, and it was difficult to stick them at regular positions on the handrail surface of the belt. Further, when the film is thin when the belt conveyor film is pressed against the handrail surface of the belt with a squeegee or a roller during the pasting operation, the film may be damaged.
[0008]
Furthermore, when the laminated film is stuck on the belt, air bubbles are generated between the laminated film layers during the sticking operation, or air bubbles remain between the laminated films, and the air bubbles move by driving the belt to be aggregated. In addition to being gradually enlarged, the appearance is not good, the adhesive strength is weakened, and the advertisement display such as a mark is deformed. This air bubble is removed by hand at present.
[0009]
The film for a conveyor belt according to the present invention solves such a conventional problem, and can efficiently attach the belt to the handrail surface at a regular position without damaging or stretching the film. . Moreover, the film for conveyor belts which aims at preventing the generation | occurrence | production of the air bubble field which generate | occur | produces at the time of sticking to the belt handrail surface of a film is provided.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a belt conveyor film that is attached to a handrail surface of a conveyor belt and displays information, and the information is printed on the front side of a long substrate, and the back side. A base film having an adhesive layer formed thereon, and an overfilm that covers the entire printed display side of the base film, has ears formed on both sides, and has an adhesive layer formed on the back surface, are arranged on a central axis of the base film. And joining the release film on the back side of the laminated film, and having a stretch ratio of about 0.005 to 0.2% with respect to the over film on the surface of the over film. It is characterized in that a hard film is joined in a peelable manner.
[0011]
As a result, when the belt is attached to the handrail surface, even if the process of repeatedly pressing and rubbing the film surface with a squeegee or roller is repeated repeatedly, the over-film has an elongation phenomenon due to the presence of the hard guide film. Prevent it from occurring. Furthermore, the guide film undergoes the phenomenon of deformation of the display of marks, logos, barcodes, secondary codes, symbols, etc. on the base film due to the deformation of the base film through the over film in the above-mentioned crimping and friction process. Can be prevented.
[0012]
In addition, the overfilm is supported by a hard guide film until both sides of the overfilm are attached to the handrail surface of the belt. Therefore, when the belt is attached to the handrail surface, the overfilm is overcoated with a hard film. To prevent distortion caused by stretching of the printing surface. Further, it is possible to prevent these both end portions from freely hanging down and inadvertently sticking to the target site of the belt handrail surface. Therefore, it is possible to avoid the inefficiency or impossibility of original sticking work.
[0013]
In addition, the over film is joined with the ears on both sides of the base film being left, and the over film is joined in a state of being substantially coaxial with the center axis of the base film, and the thin ears are in close contact with the handrail surface. Can be attached to both sides of the handrail surface accurately and without waste. Therefore, it is possible to reduce the chance that the passenger tries to peel off the base film from the handrail surface of the belt. In addition, by sticking only the base film to both ends of the handrail surface of the belt, the entire transparent base film can be easily expanded and contracted, and the belt handrail surface is deformed following deformation and vibration during movement, It can be made difficult to peel off from the handrail surface of the belt.
[0014]
According to a second aspect of the present invention, there is provided a belt conveyor film having two perforations extending through the belt conveyor film of the first aspect along the longitudinal direction of the overfilm to the base film. Is formed.
[0015]
As a result, when the over film and the base film are joined to the belt V, air bubbles are generated between the laminated film layers. If the air bubbles are present on the adhered film, the adhesive strength is weakened, causing film damage. That is, in the longitudinal direction of the overfilm, air bubbles generated when the laminated overfilm and the base film are joined to the belt V do not stay as bubbles between the base film and the overfilm and the belt V when the belt is driven. Along with the two perforated cuts that penetrate to the base film, the air is automatically exhausted to the outside. As a result, it is possible to increase the mutual adhesion and sticking strength between the base film and the overfilm.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are longitudinal sectional views showing an example of a belt conveyor film adhered to a handrail surface of a belt conveyor such as an escalator, and FIG. 3 is a belt conveyor film adhered to a handrail surface of a belt such as an escalator. It is a longitudinal cross-sectional view which shows the state which stuck.
As shown in each figure, this belt conveyor film is composed of a base film 2 having a printing layer 1 on one surface (upper surface), and a thin overfilm adhered on the base film 2 via an adhesive layer 5. 6, a release paper (separator) 4 adhered to the lower surface of the laminated overfilm 6 and the base film 2 via an adhesive layer 3, and an adhesive that is easily bonded to the upper surface of the overfilm 6. It is the structure which overlap | superposed the guide film 7 which has the layer 8 on the lower surface.
[0017]
Here, the base film 2 has the print layer 1 on which various information related to advertisements, guidance, and the like are printed by characters, figures, pattern symbols, and the like, at a substantially central portion in the width direction. As this base film 2, for example, a white urethane-based resin film having a thickness of about 20 to 80 microns, preferably about 30 to 50 microns is suitably used. Note that the release paper 4 adhered to the lower surface of the base film 2 has a width dimension substantially equal to the width of the overfilm 6, that is, the width including the ear portion 9.
[0018]
The overfilm 6 is substantially coaxial with the central axis x of the base film 2 and is joined by extending the ears 9 on both sides. The ears 9 of the overfilm 6 are extended with the adhesive layer 5 so as to be wider in the width direction than the base film 2. By sticking the ears 9 to the back sides of both sides of the handrail surface of the belt, the ears 9 are stuck to the side surfaces of the belt V, and the base film 2 is prevented from being inadvertently peeled off due to mischief or the like. Since the ear portion 9 of the overfilm 6 is thin and highly stretchable, it is possible to reduce the chance of peeling off from the edge portion. The overfilm 6 may be made of a material that is as thin as possible in order to cope with the deformation of the belt. For example, a transparent or lightly colored urethane having a thickness of 20 to 80 microns, preferably about 30 to 50 microns. A resin film is preferably used.
[0019]
In particular, the ear film 9 of the overfilm 6 has only one layer, and can maintain a stretch rate of about 3 to 5 times as a film for a belt conveyor, for example. For this reason, peeling does not occur even when the handrail surface of the belt V is deformed, deformed, or vibrated.
[0020]
The guide film 7 uses a hard film that is thicker than the overfilm 6. For example, it is made of a Tetron film having a thickness of 100 to 150 microns and has the adhesive layer 8 on the lower surface. The guide film 7 is not limited in coloration, and is preferably a hard film having an expansion / contraction ratio of 0.005 to 0.2% as a whole. In this way, by using a hard film that hardly expands and contracts with an expansion ratio of 0.005 to 0.2%, deformation of the overfilm 6 and the base film 2 is prevented at the time of sticking. A paper film (release paper) is used on the lower surface of the guide film 7 through an adhesive 8. The guide film 7 is peeled off from the overfilm 6 after being applied to the belt V.
[0021]
As described above, the guide film 7 is formed of a hard material having no shrinkage compared to the base film 2 and the overfilm 6, and can be formed of paper having an increased thickness and height. In this way, the guide film 7 holds the overfilm 6 so as not to hang down until just before the belt V is attached to the handrail surface. It is possible to avoid sticking to unintended parts.
[0022]
Further, when the surface of the guide film 7 is strongly pressed and rubbed repeatedly with a squeegee or a roller during construction, the lower film 6 and the base film 2 are prevented from being damaged or stretched. Thereby, it is possible to prevent the marks, logos, barcodes, secondary codes, symbols, and the like printed on the base film 2 from being deformed.
[0023]
As shown in FIG. 2, the belt conveyor film has a base film 2 having a print layer 1 and a guide film 7 and a film component A in which a release paper 4 is pasted via an adhesive layer 3. The film constituent part B, on which the release paper 8 is pasted via the adhesive layer 5, is bonded to the lower surface of the overfilm, almost coaxially with the central axis x of the base film 2, leaving the ears 9. In this combination, the overfilm 6 and the guide film 7 are bonded to the surface of the printing layer 1 of the base film 2 via the adhesive layer 5. Therefore, a belt conveyor film having an integral structure as shown in FIG. 1 is formed.
[0024]
As shown in FIG. 3, such a film for a convex belt is laminated with the guide film 7 as an upper surface on the handrail surface V of the endless belt after the release paper 4 is peeled off. At the time of this bonding, the characters, figures, and the like represented by the printing layer 1 are aligned so as to come to the approximate center position or plane portion in the width direction of the handrail surface V of the belt.
[0025]
At the time of this alignment, as shown in the left part of the belt conveyor film in FIG. 3, the overfilm 6 and the base film 2 are supported horizontally by the hard guide film 7. Therefore, there is no fear that both end portions hang down due to its own weight and carelessly adheres to the handrail surface V of the belt.
[0026]
In this alignment state, this time, as shown in FIG. 3, the uppermost guide film 7 is pressed and attached to both sides of the handrail surface V of the belt. In this affixing operation, in order to ensure adhesion, pressure bonding and rubbing operations with a squeegee or a roller from the guide film 7 are repeatedly performed.
[0027]
Further, in this crimping operation, the ears 9 of the overfilm 6 having the adhesive layer 5 extend outward from the left and right ends of the base film 2, so that they can be flexibly and reliably secured in a thin state. It can be brought into close contact with the arcuate side surface of the V handrail surface. Therefore, even if three-dimensional deformation occurs on the surface of the handrail surface V of the belt V, the base film 2 and the printing layer 1 below expand and contract while the transparent overfile 6 expands and contracts. Or cracks can be prevented.
[0028]
Next, the present invention forms a perforated cut 10 that penetrates to the base film 2 along the longitudinal direction of the overfilm 6. When a belt conveyor film is attached to the handrail surface of the belt V, air bubbles remain between the films 2 and 6. In addition, even after the bonding operation is completed, air bubbles generated from the adhesive layers 3 and 8 and the like may remain as air bubbles between the base film 2 and the handrail surface of the belt V or the overfilm 6. is there.
[0029]
These air bubbles deteriorate the adhesion strength between the handrail surface of the belt V, the base film 2 and the overfilm 6. For this reason, in the film for a belt conveyor of the present invention, as shown in FIG. 4, a perforated small hole or slit-shaped vertical cut 10 penetrating from the over film 6 to the base film 2 is provided. It is formed in the longitudinal direction. As a result, the remaining air bubbles are released to the outside through the notch 10. Thus, the laminated films 2 and 6 can be joined to the handrail surface of the belt V with good appearance and stability while maintaining the adhesive strength. Here, it is preferable that a plurality of cuts 10 are continuously formed in a vertical perforation along the longitudinal direction of the overfilm 6. If the shape of the notch 10 is formed in a direction intersecting with the overfilm 6, dust and dust are likely to be attached, which is not preferable.
[0030]
As a result, it is possible to reliably prevent the belt conveyor film from being peeled off from the handrail surface of the belt V, and it is possible to stably maintain the advertising display effect of characters and figures on the printed layer 1 over a long period of time. become.
[0031]
【The invention's effect】
As described above, according to the present invention, the hard guide film is stretched over the overfilm in the step of sufficiently pressing and rubbing the surface of the overfilm with a squeegee or a roller to sufficiently bond each film. It can protect against the occurrence of cracks. Furthermore, in the crimping and friction process, the base film can be prevented from being deformed, and thus the display of marks, logos, barcodes, secondary codes, symbols, etc. on the base film can be prevented from being deformed. can get.
[0032]
In addition, since the overfilm is supported by a hard guide film when the belt conveyor film is attached to the handrail surface of the belt, both ends of the overfilm are free to be attached when the belt is attached to the handrail surface. It is possible to prevent the belt from being inadvertently shifted and inadvertently sticking to the attachment target portion of the handrail surface of the belt, and as a result, there is an advantage that the attachment work can be performed efficiently.
[0033]
In addition, since the overfilm is formed wider in the width direction than the base film having the adhesive layer, the overfilm can be attached to both sides of the handrail surface of the belt so as to cover both sides of the base film. . Therefore, it is possible to reduce the chance that the passenger tries to peel off the base film from the handrail surface of the belt. In addition, since the transparent base film can be easily expanded and contracted, the belt handrail surface can be deformed following deformation and vibration during movement, and the belt handrail surface can be hardly peeled off.
[0034]
In addition, since a perforated cut is formed over the adhesive layer between the overfilm and the base film, by providing a gas vent passage for escaping air bubbles generated from adhesion, the air bubbles are It is possible to prevent air bubbles from staying between the handrail surface of the belt and the base film or between the base film and the over film. As a result, the adhesive layer allows the adjacent handrail surfaces of the belts, the base film, and the over film to be in close contact with each other, thereby increasing the adhesion strength.
