Technical field

The present invention relates to a handrail processing device, and more particularly to a configuration of a positioning means suitable for applying to a handrail such as an escalator.

Background art

[0002] Generally, an escalator ゃ a movable sidewalk or the like is provided with a movable handrail configured to move with a person in the direction in which the person is transported. This handrail is often constructed by arranging a flexible belt along an endless track. In recent years, examples of using the above handrails as an advertising medium have been increasing, and it has been practiced to actually attach a label printed with an advertisement on the surface of the handrail. Normally, labels are attached to the surface of the handrail by manually applying a label with an adhesive layer to the handrail, but the surface of the handrail is generally curved. Therefore, there is a problem that the sticking work is difficult and time-consuming.

[0003] Therefore, various devices for attaching a label to the surface of a handrail have been developed. For example, Patent Documents 1 and 2 below disclose a thermal transfer sheet attaching apparatus having a heating and pressing function for attaching a thermal transfer sheet to the surface of a handrail. Patent Document 3 below discloses a protective film to be attached to the surface of a handrail, a device for attaching the protective film, a device for peeling the protective film, and the like. Further, Patent Literature 4 below discloses a device for attaching a print sticker to a handrail of an escalator.

[0004] Also, a device for cleaning the handrail of an escalator has been developed and used. This type of cleaning device performs cleaning by applying various cleaning tools to the surface of a handrail.For example, in Patent Document 5 below, the cleaning device is rotatably attached to a main body. An apparatus having two side plates, and a pair of rollers respectively supported by the side plates, and a cleaning tool mounting base positioned by sandwiching the handrail from both sides in the width direction by the pair of rollers.

Problems to be solved by the invention

By the way, in the above-described device for attaching a film to a handrail, it is necessary to fix the device body in a state where the device main body is accurately positioned with respect to the handrail before performing the sticking process on the handrail. For this reason, the apparatus main body requires a main body fixing means for fixing the handrail to the support structure, and a position adjusting means for adjusting the position of the apparatus main body with respect to the support structure. When the apparatus is applied to a handrail, the apparatus body must be fixed by the body fixing means, and the positional relationship between the apparatus body and the handrail must be adjusted by the position adjusting means. In general, the shape and size of the handrail and the positional relationship between the handrail and the support structure are various. Therefore, the conventional apparatus has a problem that a great deal of labor is required to fix the apparatus main body and adjust the position of the handrail.

[0006] Also, handrails are installed in various places, but in many cases, they are often installed in places near the wall surfaces inside the building. In this case, since the wall surface exists immediately beside the handrail, the wall surface of the conventional device becomes an obstacle, and the device body cannot be fixed to the support structure. obtain.

[0007] On the other hand, the above-described cleaning device is configured so that positioning can be easily performed on a handrail using a roller or a spring. However, in this cleaning device, the positioning accuracy of the device main body with respect to the handrail is insufficient, and a roller having a concave roller surface is rotatably supported on a side plate rotatably mounted. However, there is a problem that the allowable range for changes in the shape and dimensions of the handrail is small and impractical.

[0008] Therefore, the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a handrail processing device that can easily and accurately position the apparatus main body with respect to the handrail. . Further, another object of the present invention is to provide an apparatus main body regardless of the installation location of a handrail. An object of the present invention is to provide a handrail processing device capable of reliably positioning a handrail with respect to the handrail. Still another object is to provide a handrail processing apparatus that can flexibly respond to changes in the shape and dimensions of the handrail.

Means for solving the problem

[0009] In view of such circumstances, a handrail processing apparatus of the present invention is a processing apparatus for performing processing on a handrail, including a main body positioning means for positioning the apparatus main body with respect to the handrail. The main body positioning means includes a pair of abutting bodies that abut against the handrail from both sides in the width direction, and a guiding means that guides the pair of abutting bodies movably in the width direction with respect to the apparatus body. Movement restricting means for restricting the pair of abutting members so that the directions of movement in the width direction are opposite to each other, and the amount of movement in the width direction is equal to each other; Biasing means for biasing inward in the direction.

[0010] In the present invention, the pair of abutting members are configured to be movable in the width direction of the handrail with respect to the apparatus main body by the guide means, so that it is possible to widely cope with the shape and dimensions of the handrail. Further, since the pair of abutting members are always biased inward by the biasing means, the pair of abutting members can be configured to abut on the handrail from both sides in the width direction. Since the movement directions of the pair of abutting members are opposite to each other and the amount of movement is regulated to be equal to each other, when the pair of abutting members abut against the handrail from both sides in the width direction, the apparatus main body. The positional relationship between the handrail and the handrail is always constant. For example, if a pair of abutting members are regulated so as to be arranged at positions in the width direction symmetrical with respect to the center axis of the apparatus main body, regardless of the width of the handrail, the center axis of the apparatus main body and the handrail can be adjusted. It always coincides with the central axis. Therefore, the device can be easily and accurately positioned with respect to the handrail. Further, since the device of the present invention is directly positioned with respect to the handrail, it is not necessary to position and fix the device with respect to the support structure of the handrail as in the conventional device, and therefore, irrespective of the structure and installation location of the handrail. There is also an effect that it can be easily mounted.

[0011] In the present invention, it is preferable that a plurality of sets of the pair of abutting members are provided at different positions in an extending direction of the handrail. According to this, a plurality of pairs of abutting bodies configured as described above are arranged at different positions in the handrail extension direction, so that the attitude of the apparatus main body (the axial direction) is changed in the handrail extension direction. Can be matched. [0012] In the present invention, it is preferable that the plurality of sets of the pair of contact bodies are configured to be movable in the width direction with respect to the apparatus body independently for each set. According to this, a plurality of pairs of abutting members are configured so as to be independently movable in the width direction with respect to the apparatus main body for each group, and thus provided at different positions in the handrail extending direction. In addition, since a pair of abutting members belonging to each group independently position the handrail in the width direction, the device main body must be moved in the extension direction of the handrail regardless of the mounting accuracy of the abutting member to the device body. It is possible to surely match.

[0013] In the present invention, the movement restricting means includes a pair of racks extending in the width direction fixed to the pair of abutting members, and a rotatably supported shaft with respect to the apparatus main body. It is preferable to have a gear or a train wheel commonly engaged with the rack. According to this, the pair of racks are connected to each other via the gears or the gear train, whereby the movement restricting means can be surely constituted by a simple and compact mechanism. Here, the gear may be one in which a gear portion that engages with one rack and a gear portion that engages with the other rack are integrally formed. When a pair of racks are arranged facing each other, a train of an odd number of gears is combined with each other, so that the pair of racks face the same side. In this case, by adopting a combination of even-numbered gears, the moving direction of the pair of racks can be made opposite to each other.

[0014] In the present invention, the contact body has a contact roller provided with a rotation axis orthogonal to the extension direction of the handrail, and rotatably supports the contact roller, and is guided in the width direction by the guide means. It is preferable that the shaft support is provided. According to this, a contact roller rotatably supported on the shaft support is provided, and the contact roller is configured to be in contact with the handrail, whereby friction between the contact body and the handrail is provided. Therefore, the relative movement between the apparatus main body and the handrail in the extension direction of the handrail can be easily and smoothly performed in a state where the apparatus main body is positioned on the handrail. Here, it is desirable that the rotation axis of the contact roller is configured to be orthogonal to the surface of the handrail (the center part of the surface of the handrail).

In the present invention, the contact roller has a roller surface inclined in a direction of the rotation axis. It is preferred to have. Since the contact roller has a roller surface that is inclined in the direction of the rotation axis (that is, one of the directions in which the rotation axis of the contact roller extends), a pinch for positioning is provided between the apparatus main body and the handrail. It is also possible to generate a supporting force in the direction of the axis of rotation that can be controlled only by pressure.Therefore, the device body can be placed on the handrail by contacting the contacting body from both sides of the handrail diagonally from above. Alternatively, it is possible to hold the apparatus main body arranged above the handrail so as not to come off from the handrail by making the contact body contact the both sides of the handrail obliquely from below. More specifically, it is preferable that the contact roller is provided with a roller surface that is formed in a conical shape or an inverted conical shape with the rotation axis as the center. In addition, the contact roller has a roller surface inclined to one side (for example, a conical surface) around the rotational axis and a roller surface inclined to the other side (for example, an inverted conical surface) around the rotational axis. It is more desirable to provide both with the roller surface.

[0016] In the present invention, it is preferable that the device main body is provided with a film sticking mechanism for sticking a film to the handrail. When a film is stuck to a handrail by this film sticking mechanism, it is extremely effective to use the main body positioning means of the present invention in that the accuracy of the sticking position of the film is easily and reliably obtained. .

FIG. 1 is a side view showing a state in which the handrail processing device 100 of the first embodiment is applied to a handrail (movable handrail of an escalator), FIG. 2 is a schematic plan view of the device 100, and FIG. It is sectional side view.

As shown in FIG. 1, the apparatus 100 of the present embodiment is positioned with respect to a handrail 12 that is configured to be movable along the outer periphery of a support structure 11 of an escalator 10, and It is for performing various processes, for example, attaching a film, cleaning a handrail, and forming a coating layer. Here, the handrail 12 is not limited to the escalator 10 and may be a handrail of other various devices such as a moving sidewalk (moving sidewalk) as long as it is configured to move. It is not limited to the handrail, and may be a normal fixed handrail. In the following embodiments, an example in which the apparatus is configured to perform a film sticking operation and an example in which a mobile handrail is used as a handrail will be described.

The device 100 in the illustrated example is configured to be used by being placed on the handrail 12 from above. The apparatus 100 includes a frame 101 and support rollers 102, 103, and 104 rotatably supported around a rotation axis horizontal to the frame 101 as a center. The frame 101 has a pair of left and right side plates connected to each other, and a support shaft for supporting the support rollers 102, 103, 104 is fixed by these side plates. A sub-frame 106 is rotatably connected to a front end of the frame 101 via a support shaft 105.

A processing mechanism 110 is attached to the frame 101. The processing mechanism 110 constitutes an apparatus main body together with the frame 101, the supporting rollers 102, 103, 104, the sub-frame 106, the finishing and the processing 107. In this embodiment, the processing mechanism 110 is a film sticking mechanism for sticking the film Y to the handrail 12. The processing mechanism 110 includes a supply roller 111 around which the film Y is wound, guide rollers 112, 113, and 114 for guiding the finolem Y, and a sticking roller 115 for pressing the finolem Y against the handrail 12 and sticking it. In addition, one or a plurality of pressure rollers 116 and brushes 117 provided in a finishing unit 107 fixed to the sub-frame 106 are provided.

In the device 100, the handrail 12 is positioned in a width direction orthogonal to an extension direction (horizontal direction in the drawing). A main body positioning means 120 for determining is attached. The main body positioning means 120 has a guide shaft 121 fixed to the frame 101, and a pair of abutting members 122, 123 guided movably along the guide shaft 121. The guide shaft 121 linearly extends in the width direction of the handrail 12, and guides and moves the contact members 122 and 123 in the width direction so as to be movable (translationally moved). In the illustrated example, a pair of parallel guide shafts 121 is provided, and both of the contact bodies 122 and 123 are guided by both of the pair of guide shafts 121 and 121. The contact members 122 and 123 are contact rollers 122A and 123A for contacting and supporting the handrail 12 from both sides in the width direction, and the contact rollers 122A and 123A are rotatable around a rotation axis orthogonal to the extension direction of the handrail 12. And shaft supporting bodies 122B and 123B.

[0024] The contact roller 122A has a roller surface 122A2 formed on the upper side and facing obliquely upward (conical surface) and a roller formed on the lower side and facing obliquely downward (inverted conical surface). Surface 122A1. The roller surface 122A2 abuts both ends of the handrail 12 from obliquely above. The contact roller 123A has the same roller surface as described above.

The shaft supports 122B, 123B are configured to be guided by the guide shaft 121 and to be movable in the width direction of the handrail 12. Racks 122C, 123C are fixed to the shaft supports 122B, 123B, and the racks 122C, 123C are arranged to face each other, and are engaged with the gear 124 from opposite sides. The gear 124 is rotatably supported by supporting portions 125 and 126 fixed to the frame 101.

An elastic member 127 composed of a coil panel or the like is connected between the contact members 122 and 123, and the contact members 122 and 123 are configured to approach each other by the elastic member 127. . That is, the contact members 122 and 123 are urged inward in the width direction by the elastic members 127, respectively.

In the main body positioning means 120, the pair of abutting members 122 and 123 (abutting rollers 122 A and 123 A) abut against the handrail 12 from both sides in the width direction. It is configured to pinch 12. At this time, the force by which the contact members 122 and 123 move inward in the width direction according to the width of the handrail 12 The movement direction of the contact members 122 and 123 is always opposite to the width direction by the racks 122C and 123C and the gear 124. Orientation and the amount of movement are regulated so that they are always the same. Therefore, the device 100 is placed on the handrail 12 and When the contact rollers 122A and 123A sandwich the handrail 12 from both sides in the width direction, the center position in the width direction of the apparatus main body and the center position in the width direction of the handrail 12 are always at a fixed distance. In other words, the position in the width direction of the apparatus body corresponding to the center position in the width direction of the handrail 12 is always constant. In the present embodiment, the center position in the width direction of the apparatus main body (the center position of the film Y) always coincides with the center position of the handrail 12 in the width direction.

[0028] The main body positioning means 120 is provided with one contact roller 122A, 123A for each of the pair of contact members 122, 123. The force extending direction of the handrail 12 in the pair of contact members. A plurality of contact rollers may be provided at different positions. In this case, if the widthwise position of the apparatus main body between the contact rollers provided at different positions in the extension direction of the handrail 12 is configured to be equal to each other, the extension direction of the handrail 12 and the axial direction of the apparatus main body And will match each other.

Actually, in the present embodiment, a plurality of (two in the illustrated example) main body positioning means 120 are independently provided at different positions in the extension direction of the handrail 12. Accordingly, the positioning in the width direction is independently performed at different positions in the extension direction of the handrail 12 by the respective main body positioning means 120, so that the extension direction of the handrail 12 and the axial direction of the device main body are different from each other. Can be matched exactly.

In the present embodiment, as shown in FIG. 1, a band-shaped film (adhesive sheet) γ having an adhesive layer on one side and a release sheet z attached so as to cover the adhesive layer are provided in advance. The laminated material X is wound around to form a supply roller 111, and the laminated material X is drawn out from the supply roller 111, is laid on guide rollers 112, 113, and 114, passes through the guide roller 114, and then is released. Z is peeled off, and the peeling sheet Z is wound around a collecting roller 119 via a guide roller 118. Then, the film Y is put on the sticking roller 115 and pulled out to the subframe 106 as it is.

In the apparatus 100 of the present embodiment configured as described above, when the contact rollers 122A and 123A are placed on the handrail 12 in a state where they are widened in the width direction, the support rollers 102 and 1 With the 03 and 104 in contact with the surface of the handrail 12, the contact rollers 122A and 123A are pressed against the handrail 12 from both sides in the width direction by the elastic force of the elastic member 127, and the positioning of the apparatus body and the handrail 12 in the width direction is performed. Is done automatically. At this time, the roller surfaces 122A2, 123A2 (123A2 are not shown) of the contact rollers 122A, 123A come into contact with both sides of the handrail 12 obliquely from above, so that the contact rollers 122A, 123A and the handrail A stress component in the vertical direction is generated between the device 12 and the device, whereby the position adjustment force S in the width direction of the device main body is smoothly performed. That is, even when the contact roller has a roller surface orthogonal to the width direction of the handrail 12, the positioning itself in the width direction of the device 100 is possible, but the vertical stress between the device 100 and the handrail 12 can be increased. Is generated only between the support rollers 102, 103, 104 and the upper surface of the handrail 12, so that the frictional resistance generated between them makes it difficult to move the device 100 relative to the handrail 12 in the width direction. However, in the case of the present embodiment, a part of the vertical stress can be borne between the contact rollers 122A, 123A and the handrail 12, so that the frictional resistance can be reduced. This makes it possible to smoothly perform the movement operation when adjusting the position of the apparatus main body in the width direction based on the elastic force of the elastic member 127.

In this embodiment, the support rollers 102, 103, and 104 are attached to the upper surface of the handrail 12 in a state where the roller surfaces 122A2 and 123A2 of the contact rollers 122A and 123A abut on both sides of the handrail 12 from above. The device 100 is placed on the handrail 12 so as to abut. However, as shown in another embodiment to be described later, the roller surfaces 122A1 and 123A1 (123A1 are not shown) of the contact rollers 122A and 123A contact both sides of the handrail 12 from below, and the contact rollers 122A and 123A , 123A and the supporting rollers 102, 103, 104 abutting from above may sandwich the handrail 12 from above and below, so that the device 100 may be mounted on the handrail 12. In this case, a part of the elastic force of the elastic member 127 also acts as a holding force for holding the device 100 on the handrail 12.

[0034] In this embodiment, when the film Y is attached to the surface of the handrail 12, the film Y previously drawn to the subframe 106 side is attached to the surface of the handrail 12. Then, the device 100 is placed on the handrail 12 in the manner described above. When the device 100 is positioned in the width direction with respect to the handrail 12 as described above, the force for manually moving the device 100 in the extension direction of the handrail 12 or the handrail while holding the device 100 is held. Move 12 in its extension direction. In this way, the film Y is attached to the surface of the handrail 12 by the attaching roller 115. At this time, when the outer edge surface of the handrail 12 is configured as a curved surface Then, both ends of the film Y on the outer edge of the handrail 12 are gradually adhered to both sides of the handrail from inside to outside by a plurality of rolling rollers 116. Finally, the outer edge of the film Y is securely adhered by the brush 117.

In the present embodiment, in order to guide the contact members 122 and 123 in the width direction of the handrail 12, guide holes (through the guide shaft 121) of the guide shaft 121 and the shaft supports 122 B and 123 B are provided. A guide means constituted by a handrail 1 2 is formed by the guide means so that the abutting members 122, 123 are linearly translated in the width direction. Can be flexibly and highly accurately adapted to the width dimension of.

[0036] Further, in order to restrict the movement of the pair of abutting bodies 122 and 123, a pair of racks 122C and 123C which are arranged opposite to each other, and which are arranged between the pair of racks and shared by the pair of racks. And a movement restricting means constituted by a gear 124 that cooperates with the pair of contact members 122 and 123. The movement restricting means reverses the directions of movement of the pair of abutting members 122 and 123 in the width direction. Since the same amount is used, the widthwise positional relationship between the apparatus main body and the handrail 12 can always be kept constant, so that the positioning of the device 100 in the width direction with respect to the handrail 12 is facilitated, and the pushing force is also reduced. Positioning accuracy can be improved.

[0037] Instead of the gear 124, a wheel train formed by combining a plurality of gears with each other is provided, and a pair of racks 122C and 123C are respectively engaged with one of the gears in the wheel train. May be. For example, a first gear coupled to one rack 122C and a second gear coupled to the other rack 123C are provided, and an intermediate gear is coupled between the first gear and the second gear. You may. Further, in this case, even if the pair of racks are not arranged facing each other, the movement restricting means having the same function as described above can be configured. For example, a pair of racks are arranged on the same side, and a first gear engaging with one rack and a second gear engaging with the other rack are provided, and a first gear and a second gear are provided. May be combined with each other.

Each of the contact rollers 222A and 223A has a rotation axis extending in a direction perpendicular to the direction in which the handrail 12 extends (in the illustrated example, a direction also perpendicular to the surface of the handrail 12). Each of the roller surfaces 222A1 and 223A1 is formed in a conical surface that faces obliquely upward and that is centered on the rotation axis. When the device 200 is mounted on the handrail 12, the roller surfaces 222A1 and 223A1 of the contact rollers 222A and 223A contact the side surfaces of the handrail 12 from obliquely below. The handrail 12 is sandwiched from both sides in the width direction by the pair of contact rollers 222A and 223A, and the vertical force is also reduced by the support rollers 202, 203 and 204 and the pair of contact rollers 222A and 223A.

Thus, the device 200 is positioned in the width direction with respect to the handrail 12 by the elastic force of the elastic member 227, and is held by the handrail 12 in the vertical direction by the elastic force of the elastic member 227. It is in a state.

Further, in the present embodiment, a supply roller 211 formed by winding the laminate X, guide rollers 212 and 213 for laying the laminate X, and a film Y to be adhered to the handrail 12 are attached to the processing mechanism 210. A roller 215, a guide roller 218 for laying the release sheet Z, a collection roller 219 for winding the release sheet Z, and the like are provided. Although these are slightly different from each other in construction, they have basically the same configuration as the embodiment described above. However, in the present embodiment, as shown in FIG. 4 and FIG. It is configured so that it can be used. Further, as shown in FIG. 6, a torque keeper 211B is interposed between the drum 211A of the supply roller 211 and the frame 201, and a constant drawing torque is always required to pull out the laminate X from the supply roller 211.
