Description

  The present invention relates to a film for a conveyor belt 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.

  The handrail surface of the belt conveyor, called an escalator or moving sidewalk, plays an important role in ensuring user safety, but on the other hand, dirt adheres to the user's touch, and this dirt is left as it is Since it is unsanitary and unsightly, it is necessary to always clean the belt and keep the handrail surface of the belt clean.

  Such dirt on the handrail surface is often cleaned by mechanical work, but the handrail surface of the belt is only temporarily temporarily cleaned, and after a while, strong dirt is attached again. As a result, a troublesome and time-consuming cleaning operation has to be performed periodically, and a great deal of labor has been spent on the cleaning operation.

  Further, since the belt is deformed and the aesthetic appearance is impaired by frequently performing such cleaning work, the belt needs to be replaced, which increases the maintenance cost.

On the other hand, by applying a protective film to the handrail surface of the belt, troublesome cleaning work is not required, sanitary use is possible with simple wiping, and information such as advertisements and guidance is transferred to the handrail surface of the belt. A film for a conveyor belt which can be displayed on the upper side is provided (for example, see Patent Document 1).
JP-T-2002-537200

However, a conventional film for a belt conveyor uses a stack of films of the same quality and the same thickness. For this reason, when the film is mechanically pressed against the handrail surface when attaching the belt to the handrail surface, a distortion phenomenon occurs in which the printed film stretches, and the advertisement display such as marks is deformed. There was a problem that it would.
Also, since the film is elongated and flexible as a whole, a part of the film hangs down during the work of sticking to the handrail surface of the belt, and a part of the adhesive layer is formed on an object other than the handrail surface of the belt or the handrail surface of the belt. There was a problem in that it was inadvertently touched and stuck to a part of the belt, making it difficult to stick it to a regular position on the handrail surface of the belt. Furthermore, when the film for a belt conveyor is pressed against the handrail surface of the belt with a squeegee or a roller at the time of the sticking operation, the film may be damaged if the film is thin.

  Furthermore, when the laminated film is adhered to the belt, air bubbles are generated between the laminated film layers during the attaching operation, or air bubbles remain between the film laminations, and the air bubbles move by driving the belt and are aggregated. In addition to the problem of not only poor appearance but also weakening of the adhesive strength, there is also a problem that an advertisement display such as a mark is deformed. At present, the removal of the air bubbles is manually performed.

  The conveyor belt film according to the present invention solves such a conventional problem, and can efficiently attach a belt to a regular position on a handrail surface without breaking or elongating the film. . Further, there is provided a film for a conveyor belt for preventing the occurrence of air bubbles generated when the film is attached to a belt handrail surface.

  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, wherein information is printed on the front side of a long base material and on the back side. A base film having an adhesive layer formed thereon, and an overfilm which covers the entire print display side of the base film and has ears formed on both sides thereof and has an adhesive layer formed on the back surface thereof, the center axis of the base film. The release film is bonded to the back side of the laminated film, and the expansion and contraction ratio of the over film is about 0.005 to 0.2% with respect to the over film. A hard film is detachably joined.

  Due to this, even when the process of repeatedly applying pressure and friction using a squeegee or roller on the surface of the film during the application of the belt to the handrail surface is performed, the elongation phenomenon occurs in the over film due to the presence of the hard guide film. Prevent it from occurring. Further, in the guide film, the base film is deformed through the over film in the above-mentioned press-fitting and friction steps, and the mark, logo, bar code, secondary code, symbol, etc. on the base film is deformed. Can be prevented.

  The over film is supported by a rigid guide film until both sides of the over film are adhered to the handrail surface of the belt. To prevent distortions caused by stretching of the printing surface. In addition, it is possible to prevent the both ends from hanging freely and inadvertently displacing and adhering to the application target site on the handrail surface of the belt. Therefore, it is possible to prevent the original sticking work from being inefficient or impossible.

  Furthermore, the overfilm is joined in a state of being substantially coaxial with the center axis of the base film, leaving the ears on both sides of the base film, and since the thin ears are in close contact with the handrail surface, the belt is Can be stuck accurately on both sides of the handrail surface without waste. Therefore, it is possible to reduce the chance that the passenger tries to peel the base film from the handrail surface of the belt by mischief. In addition, by adhering 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 deforms and deforms during movement of the handrail surface of the belt, It is possible to make it difficult for the belt to peel off from the handrail surface.

  The film for a belt conveyor according to a second aspect of the present invention is a belt-conveyor film according to the first aspect, in which two perforations penetrate to the base film along the longitudinal direction of the overfilm of the film. Is formed.

  Thus, when the over film and the base film are joined to the belt V, air bubbles are generated between the laminated film layers. The presence of air bubbles in the adhered film weakens the adhesive strength, causing the film to break. That is, air bubbles generated in joining the laminated over film and the base film to the belt V do not stay as bubbles between the base film, the over film, and the belt V when the belt is driven. Along the base film, air is automatically exhausted to the outside by two perforations. As a result, it is possible to increase the mutual adhesion and the adhesion strength between the base film and the over film.

  As described above, according to the present invention, in the step of repeatedly applying pressure and friction strongly to the surface of the over film by using a squeegee or a roller to sufficiently adhere the respective films, the hard guide film may be stretched to the over film. It can prevent cracks from occurring. Further, in the crimping and friction steps, the base film can be prevented from being distorted, so that the mark, logo, bar code, secondary code, symbol, etc. on the base film can be prevented from being deformed. can get.

  Also, when the film for the belt conveyor is adhered to the handrail surface of the belt, the overfilm is supported by a hard guide film, so that both ends of the overfilm can be freed when attaching to the handrail surface of the belt. It is possible to prevent the belt from hanging down and inadvertently displacing the handrail surface of the belt to the intended application site, and as a result, there is obtained an advantage that the application can be efficiently performed.

  Further, since the over film is formed wider in the width direction than the base film having the adhesive layer, the over film can be attached to both side portions of the handrail surface of the belt so as to cover both side portions of the base film. . Therefore, it is possible to reduce the chance that the passenger tries to peel the base film from the handrail surface of the belt by mischief. Further, since the transparent base film can be easily expanded and contracted, it is deformed to follow the deformation and vibration during movement of the handrail surface of the belt, and an effect that the belt is hardly peeled off from the handrail surface is obtained.

  Also, since a perforated cut is formed over the adhesive layer between the over film and the base film, by providing a gas vent passage for releasing air bubbles generated from bonding, the air bubbles are Air bubbles can be prevented from remaining between the handrail surface of the belt and the base film or between the base film and the overfilm. As a result, the adhesive layer enables the handrail surface of the adjacent belt, the base film, and the over film to be in close contact with each other, and the bonding strength can be increased.

An embodiment of the present invention will be described below with reference to the drawings.
1 and 2 are longitudinal sectional views showing an example of a belt conveyor film attached to a handrail surface of a belt conveyor such as an escalator. FIG. 3 is a belt conveyor film attached 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 the drawings, this film for a belt conveyor is a base film 2 having a printed layer 1 on one surface (upper surface), and a thin overfilm adhered on the base film 2 with an adhesive layer 5 interposed therebetween. 6, a release paper (separator) 4 attached to the lower surface of the laminated over film 6 and the base film 2 via an adhesive layer 3, and an adhesive which is bonded to the upper surface of the over film 6 and is easily peeled. This is a configuration in which a guide film 7 having a layer 8 on the lower surface is overlapped.

  Here, the base film 2 has the print layer 1 in which various information related to advertisements, guidance, and the like are printed by characters, graphics, pattern symbols, and the like at substantially the center in the width direction. As the base film 2, for example, a white urethane resin film having a thickness of 20 to 80 microns, preferably about 30 to 50 microns is suitably used. Note that the release paper 4 attached to the lower surface of the base film 2 has a width substantially equal to the width of the overfilm 6, that is, the width including the ears 9.

  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 over film 6 are extended with the adhesive layer 5 in the width direction as compared with the base film 2 and extended. By making the ears 9 adhere to the back side of both sides of the handrail surface of the belt, the ears 9 come into close contact with the side surface of the belt V and prevent the base film 2 from being accidentally peeled off due to mischief or the like. Since the ears 9 of the overfilm 6 are thinner and have higher elasticity, the chance of peeling off from the fore-edge portion can be reduced. The overfilm 6 may be made of a material as thin as possible to cope with the deformation of the belt. For example, a transparent or thinly colored urethane having a thickness of 20 to 80 microns, preferably about 30 to 50 microns. A resin film is preferably used.

  In particular, the over film 6 has only one ear portion 9 and can maintain a stretch ratio 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.

  The guide film 7 uses a hard film thicker than the over film 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 terms of coloring, and is preferably a hard film having a stretching ratio of 0.005 to 0.2% as a whole. By using a hard film having an expansion / contraction ratio of 0.005 to 0.2% which hardly expands / contracts, deformation of the over film 6 and the base film 2 at the time of sticking is prevented. A paper film (release paper) is used on the lower surface of the guide film 7 with an adhesive 8 interposed therebetween. The guide film 7 is peeled off from the over film 6 after being applied to the belt V.

  As described above, the guide film 7 is formed of a hard material having no shrinkage as compared with the base film 2 and the overfilm 6, and can be formed of paper having a large thickness and a high height. As described above, since the guide film 7 holds the overfilm 6 so as not to hang down until immediately before the belt V is attached to the handrail surface, the overfilm 6 is inadvertently attached to the handrail surface of the belt during the operation. Can be avoided from sticking to unintended parts.

  Further, when the surface of the guide film 7 is repeatedly pressed and rubbed with a squeegee or a roller at the time of construction, the lower film 6 and the base film 2 are prevented from being damaged or partially stretched. As a result, it is possible to prevent the marks, logos, bar codes, secondary codes, symbols and the like printed on the base film 2 from being deformed.

  As shown in FIG. 2, the film for a belt conveyor has a film component A in which a release paper 4 is adhered to a base film 2 having a print layer 1 via an adhesive layer 3 and a guide film 7. A film component B, on which a release paper 8 is adhered via an adhesive layer 5 to the lower surface of the overfilm, is joined substantially coaxially with the central axis x of the base film 2 while leaving the ears 9. In this combination, the overfilm 6 and the guide film 7 are bonded to the printing layer 1 surface of the base film 2 via the adhesive layer 5. For this reason, an integrated film for a belt conveyor as shown in FIG. 1 is formed.

  As shown in FIG. 3, the film for a conveyor belt having such an integral structure is laminated with the guide film 7 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 and graphics represented by the print layer 1 are positioned so as to be located substantially at the center of the handrail surface V of the belt in the width direction or at a flat portion.

  At the time of this alignment, the over film 6 and the base film 2 are horizontally supported by a hard guide film 7, as shown on the left side of the film for a belt conveyor in FIG. Therefore, there is no fear that both ends will hang down by its own weight and will be inadvertently adhered to the handrail surface V of the belt.

  In such an alignment state, as shown in FIG. 3, the uppermost guide film 7 is pressed so as to be wound around both sides of the handrail surface V of the belt. In addition, in this attaching operation, in order to secure adhesion, pressure operation and friction operation with a squeegee or a roller from above the guide film 7 are repeatedly performed.

  In this crimping work, since the ears 9 of the over film 6 having the adhesive layer 5 extend outward at both left and right ends of the base film 2, the over film 6 can be flexibly and securely placed in a thin state. It can be in close contact with the arc-shaped side surface of the handrail surface of the V. Therefore, even if three-dimensional deformation occurs on the surface of the handrail surface V of the belt V during rolling, the base film 2 and the printing layer 1 under the lower layer expand and contract while the transparent overfile 6 expands and contracts. Or cracks can be prevented.

  Next, in the present invention, perforated cuts 10 are formed along the longitudinal direction of the overfilm 6 and penetrate to the base film 2. When a film for a belt conveyor is mounted on the handrail surface of the belt V, air bubbles remain between the films 2 and 6. Further, even after the bonding operation is completed, air bubbles generated from the adhesive layers 3, 8 and the like may remain as air bubbles between the base film 2 and the handrail surface of the belt V or the over film 6. is there.

  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, as shown in FIG. 4, a perforated small hole or a slit-shaped vertical slit 10 penetrating from the over film 6 to the base film 2 is provided in the film for a belt conveyor of the present invention. Formed in the longitudinal direction. As a result, the staying air bubbles are discharged to the outside through the cuts 10. Thereby, the laminated films 2 and 6 can be stably and beautifully joined to the handrail surface of the belt V while maintaining the adhesive strength. Here, it is preferable that a plurality of cuts 10 are formed continuously in the shape of a vertical thin perforation along the longitudinal direction of the overfilm 6. If the shape of the cut 10 is formed in a direction intersecting with the overfilm 6, dust and dirt tend to be formed, which is not preferable.

  As a result, peeling of the belt conveyor film from the handrail surface of the belt V can be reliably prevented, and the display effect of the advertisement using the characters and figures on the print layer 1 can be stably maintained over a long period of time. become.
