Description

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

  In general, escalators, mobile sidewalks, and the like are provided with mobile handrails that are configured to move with the cover in the direction of human conveyance. In many cases, the handrail is configured by arranging a flexible belt along an endless track. In recent years, there have been an increasing number of cases where the handrail as described above is used as an advertising medium, and a label printed with an advertisement is actually attached to the surface of the handrail. Usually, in order to attach a label to the surface of a handrail, a label having an adhesive layer is manually attached to the handrail. However, the surface of the handrail is generally a curved surface. There is a problem that wearing work is difficult and time-consuming.

  Therefore, various devices are currently being developed for attaching labels to the surface of handrails. For example, in Patent Documents 1 and 2 below, a thermal transfer sheet pasting apparatus having a heating and pressing function for sticking a thermal transfer sheet to the surface of a handrail is disclosed. Moreover, in the following patent document 3, a protective film adhered to the surface of a handrail, an apparatus for attaching the protective film, an apparatus for peeling the protective film, and the like are disclosed. Furthermore, the following patent document 4 discloses an apparatus for attaching a print seal to an escalator handrail.

Also, an apparatus for cleaning an escalator handrail has been developed and used. This type of cleaning device performs cleaning by applying various cleaning tools to the surface of the handrail. For example, in Patent Document 5 below, 2 attached to the main body is rotatable. Disclosed is an apparatus having a cleaning tool mounting base that includes a pair of side plates and a pair of rollers that are pivotally supported by the side plates and is positioned by sandwiching a handrail from both sides in the width direction by the pair of rollers. Has been.

  By the way, in the apparatus which sticks a film to the handrail mentioned above, before performing the sticking process with respect to a handrail, it is necessary to fix the apparatus main body in the state positioned correctly with respect to the handrail. The apparatus main body requires main body fixing means for fixing to the support structure of the handrail and position adjusting means for adjusting the position of the apparatus main body with respect to the support structure. When the apparatus is applied to the handrail, the apparatus main body must be fixed by the main body fixing means, and the positional relationship between the apparatus main 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, in the conventional apparatus, there is a problem that a large amount of labor is required to fix the apparatus main body and adjust the position with respect to the handrail.

  In addition, handrails are installed in various places, but in many cases, the handrails are often placed near a wall surface inside the building. In this case, since the wall surface is present on the immediate side of the handrail, in the conventional apparatus, a situation may occur in which the wall surface becomes an obstacle and the apparatus main body cannot be fixed to the support structure.

  On the other hand, the above-described cleaning device is configured so that the handrail can be easily positioned 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 pivotally supported on the side plate that is rotatably attached. There is a problem that an allowable range for a change in shape and size is small and not practical.

  SUMMARY OF THE INVENTION The present invention solves the above-described problems, and an object of the present invention is to provide a handrail processing apparatus capable of easily and accurately positioning the apparatus main body with respect to the handrail. Another object of the present invention is to provide a handrail processing apparatus capable of reliably positioning the apparatus main body with respect to the handrail regardless of the installation location of the handrail. Another object is to provide a handrail processing apparatus that can flexibly cope with changes in the shape and dimensions of the handrail.

  In view of such circumstances, the handrail processing device of the present invention is a processing device for performing processing on a handrail, comprising a main body positioning means for positioning the device main body with respect to the handrail. A pair of abutting bodies that abut against the handrail from both sides in the width direction, guide means for guiding the pair of abutting bodies movably in the width direction with respect to the apparatus main body, and the pair of abutting bodies, respectively. The movement restricting means for restricting the direction of movement of the contact body in the width direction to be opposite to each other and the amount of movement in the width direction being equal to each other, and the pair of contact bodies are urged inward in the width direction Biasing means.

  In the present invention, the pair of contact bodies can be moved in the width direction of the handrail with respect to the apparatus main body by the guide means, so that the shape and size of the handrail can be widely supported. In addition, since the pair of abutting bodies is always urged inward by the urging means, the pair of abutting bodies can be configured to abut against the handrail from both sides in the width direction. Since the direction of movement of the abutting bodies is opposite to each other and the amount of movement is regulated to be equal to each other, when the pair of abutting bodies abut against the handrail from both sides in the width direction, the device main body and the handrail The positional relationship in the width direction is always constant. For example, if the pair of abutting bodies are regulated so as to be arranged at positions symmetrical in the width direction with respect to the central axis of the apparatus main body, the central axis of the apparatus main body and the handrail regardless of the width dimension of the handrail It always coincides with the central axis. Therefore, the apparatus can be easily and accurately positioned with respect to the handrail. Furthermore, since the apparatus of the present invention is positioned directly with respect to the handrail, it is not necessary to position and fix the support structure of the handrail unlike the conventional apparatus, so it is easy regardless of the structure and installation location of the handrail. There is also an effect that it can be attached to.

  In the present invention, it is preferable that a plurality of sets of the pair of contact bodies are provided at different positions in the extension direction of the handrail. According to this, a plurality of sets of the pair of contact bodies configured as described above are arranged at different positions in the extension direction of the handrail, so that the posture (its axial direction) of the apparatus main body is set in the extension direction of the handrail. Can be matched.

  In the present invention, the plurality of sets of the pair of abutting bodies are preferably configured to be movable in the width direction with respect to the apparatus main body independently for each set. According to this, a plurality of pairs of abutments are configured to be movable in the width direction with respect to the apparatus main body independently for each group, thereby being provided at different positions in the handrail extension direction. Since the pair of abutment members belonging to this group independently position in the width direction with respect to the handrail, the device body can be reliably secured in the extension direction of the handrail regardless of the accuracy of attachment of the contact body to the device body. It becomes possible to match.

  In the present invention, the movement restricting means is a pair of racks extending in the width direction fixed to the pair of abutting bodies, and rotatably supported with respect to the apparatus main body. It is preferable to have a gear or a gear train that meshes in common. According to this, by setting the pair of racks to mesh with each other via a gear or a gear train, the movement restricting means can be reliably configured with a simple and compact mechanism. Here, the gear may be configured such that a gear portion meshing with one rack and a gear portion meshing with the other rack are integrally formed. Further, as a train wheel, when a pair of racks are arranged to face each other, by adopting an odd number of gears meshed with each other, the pair of racks face the same side. In this case, the moving direction of the pair of racks can be made opposite to each other by adopting a gear in which an even number of gears are engaged with each other.

  In the present invention, the contact body includes a contact roller having a rotation axis perpendicular to the extending direction of the handrail, and a shaft that rotatably supports the contact roller and is guided in the width direction by the guide means. It is preferable to have a support. According to this, the contact roller rotatably supported with respect to the shaft support body is provided, and the contact roller is configured to contact the handrail so that the friction between the contact body and the handrail is reduced. Therefore, relative movement between the apparatus main body and the handrail in the extension direction of the handrail can be performed easily and smoothly with the apparatus main body 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 portion of the surface of the handrail).

  In the present invention, the contact roller preferably has a roller surface inclined in the direction of the rotation axis. Since the contact roller has a roller surface inclined in the direction of the rotation axis, it is possible to generate not only the clamping pressure for positioning but also the support force in the direction of the rotation axis between the device body and the handrail. Therefore, the main body of the apparatus is placed on the handrail by bringing the contact body into contact with both sides of the handrail from obliquely above, or the contact body is brought into contact with both sides of the handrail from obliquely below. Thus, it is possible to hold the apparatus main body arranged above the handrail so as not to be detached from the handrail. More specifically, the contact roller is preferably provided with a roller surface configured in a conical surface shape or an inverted conical surface shape with the rotation axis as the center. Further, the contact roller has a roller surface that is inclined to one side along the rotation axis around the rotation axis (for example, a conical surface) and a roller that is inclined to the other side of the rotation axis (for example, an inverted conical surface). It is more desirable to provide both surfaces.

  In this invention, it is preferable that the said apparatus main body is provided with the film sticking mechanism for sticking a film to the said handrail. When sticking a film to a handrail by this film sticking mechanism, it is very effective to use the main body positioning means of the present invention in that the accuracy of the sticking position of the film can be obtained easily and reliably.

  As shown in FIG. 1, the apparatus 100 of the present embodiment is positioned with respect to a handrail 12 configured to be movable along the outer peripheral portion of the support structure 11 of the escalator 10, and performs various processes on the handrail 12. For example, it is for performing sticking of a film, cleaning of a handrail, formation of a coating layer, and the like. 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. Not only a type handrail but a normal fixed handrail may be used. In the following embodiments, an example configured as an apparatus for performing a film sticking operation and an example targeting a mobile handrail as a handrail will be described.

  The illustrated apparatus 100 is configured to be mounted on the handrail 12 from above. The apparatus 100 includes a frame 101 and support rollers 102, 103, and 104 that are rotatably supported around a rotation axis that is horizontal to the frame 101. The frame 101 has a pair of left and right side plates connected to each other, and support shafts that support the support rollers 102, 103, and 104 are fixed by these side plates. A subframe 106 is rotatably connected to the front end portion of the frame 101 via a support shaft 105.

  A processing mechanism 110 is attached to the frame 101. The processing mechanism 110 constitutes the main body of the apparatus together with the frame 101, the support rollers 102, 103, 104, the subframe 106, and the finishing processing unit 107. In the present 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 wound with the film Y, guide rollers 112, 113, and 114 for guiding the film Y, an adhesion roller 115 that presses and adheres the film Y to the handrail 12, One or a plurality of rolling rollers 116 and a brush 117 disposed in the finishing processing unit 107 fixed to the subframe 106 are provided.

  The apparatus 100 is provided with a main body positioning means 120 for positioning the handrail 12 in the width direction orthogonal to the extending direction (the left-right direction in the drawing). The main body positioning means 120 includes a guide shaft 121 fixed to the frame 101 and a pair of contact bodies 122 and 123 that are movably guided along the guide shaft 121. The guide shaft 121 extends linearly in the width direction of the handrail 12 and guides the contact bodies 122 and 123 so that they can move (translate) in the width direction. In the illustrated example, a pair of parallel guide shafts 121 are provided, and the contact bodies 122 and 123 are both guided by the pair of guide shafts 121 and 121. Abutting bodies 122 and 123 are abutting rollers 122A and 123A for abutting and supporting the handrail 12 from both sides in the width direction, and the abutting rollers 122A are rotatably supported around a rotation axis perpendicular to the extending direction of the handrail 12. Shaft supports 122B and 123B.

  The contact roller 122A includes a roller surface 122A1 formed on the upper portion and facing obliquely upward (conical surface), and a roller surface 122A2 formed on the lower portion and facing obliquely downward (reverse conical surface). It has. The roller surface 122A2 abuts against both ends of the handrail 12 obliquely from above. The contact roller 123A also has the same roller surface as described above.

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

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

  In the main body positioning means 120, the pair of contact bodies 122 and 123 (contact rollers 122A and 123A) are in contact with the handrail 12 from both sides in the width direction, and the handrail 12 is pinched by the elastic force of the elastic member 127. It is configured. At this time, the contact bodies 122 and 123 move inward in the width direction in accordance with the width of the handrail 12, but the movement directions of the contact bodies 122 and 123 are always opposite to the width direction by the racks 122C and 123C and the gear 124. The amount of movement is regulated to be always the same. Therefore, when the apparatus 100 is placed on the handrail 12 and the contact rollers 122A and 123A sandwich the handrail 12 from both sides in the width direction, the center position of the apparatus body in the width direction and the width direction of the handrail 12 are set. The center position is always at a certain distance. In other words, the position in the width direction of the apparatus main body corresponding to the center position in the width direction of the handrail 12 is always constant. In the present embodiment, the center position of the apparatus main body in the width direction (the center position of the film Y) is configured to always coincide with the center position of the handrail 12 in the width direction.

  The main body positioning means 120 is provided with one contact roller 122A, 123A for each of the pair of contact bodies 122, 123, but the extension direction of the handrail 12 in the pair of contact bodies is different. A plurality of contact rollers may be provided at the position. In this case, if the positions in the width direction of the apparatus main body between the contact rollers provided at different positions in the extension direction of the handrail 12 are configured to be equal to each other, the extension direction of the handrail 12 and the axial direction of the apparatus main body 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. As a result, the positioning in the width direction is independently performed at different positions in the extension direction of the handrail 12 by the main body positioning means 120, so that the extension direction of the handrail 12 and the axial direction of the apparatus main body are exactly matched. be able to.

  In this embodiment, as shown in FIG. 1, a laminate having a strip-shaped film (sticking sheet) Y having an adhesive layer on one side and a release sheet Z attached to cover the adhesive layer in advance. X is wound around the supply roller 111, the laminated material X is pulled out from the supply roller 111, installed on the guide rollers 112, 113, 114, and after passing through the guide roller 114, the release sheet Z is peeled off from the film Y. The release sheet Z is wound around the collection roller 119 via the guide roller 118. Then, the film Y is installed on the adhering roller 115 and pulled out to the subframe 106 side 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 spread in the width direction, the support rollers 102, 103, and 104 are moved. 12, the contact rollers 122 </ b> A and 123 </ b> A are pressed against the handrail 12 from both sides in the width direction by the elastic force of the elastic member 127, and the apparatus body and the handrail 12 are automatically positioned in the width direction. Is called.

  At this time, the roller surfaces 122A2 and 123A2 (123A2 not shown) of the contact rollers 122A and 123A contact the both sides of the handrail 12 obliquely from above, so that the contact rollers 122A and 123A and the handrail 12 A stress component in the vertical direction is generated in this, and thereby the position adjustment in the width direction of the apparatus 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, positioning in the width direction of the apparatus 100 can be performed, but the vertical stress between the apparatus 100 and the handrail 12 can be determined. Is generated only between the support rollers 102, 103, 104 and the upper surface of the handrail 12, it is considered that it is difficult to move the device 100 in the width direction with respect to the handrail 12 due to the frictional resistance generated between them. However, in the case of this embodiment, a part of the stress in the vertical direction can be borne even between the contact rollers 122A, 123A and the handrail 12, so that the frictional resistance can be reduced, It is possible to smoothly perform the moving 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 the present embodiment, the support rollers 102, 103, and 104 are in contact with the upper surface of the handrail 12 in a state where the roller surfaces 122 A 2 and 123 A 2 of the contact rollers 122 A and 123 A are in contact with both sides of the handrail 12 from above. The apparatus 100 is disposed on the handrail 12. However, as shown in another embodiment to be described later, roller surfaces 122A1 and 123A1 (123A1 not shown) of the contact rollers 122A and 123A abut on both sides of the handrail 12 from below, and the contact rollers 122A, The apparatus 100 may be configured to be mounted on the handrail 12 in such a manner that the handrail 12 is sandwiched from above and below by 123A and the support rollers 102, 103, and 104 that are in contact from above. In this case, 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.

  In this embodiment, when the film Y is stuck on the surface of the handrail 12, the film Y previously drawn to the subframe 106 side is stuck on the surface of the handrail 12, and then the above-mentioned. In this way, the apparatus 100 is placed on the handrail 12. When the apparatus 100 is positioned in the width direction with respect to the handrail 12 as described above, the apparatus 100 is manually moved in the extension direction of the handrail 12 or the handrail 12 is held while the apparatus 100 is held. Is moved in the extension direction. In this way, the film Y is stuck on the surface of the handrail 12 by the sticking roller 115. At this time, when the outer edge portion surface of the handrail 12 is formed in a curved surface shape, thereafter, both end portions of the film Y on the outer edge of the handrail 12 are opposed to both side portions of the handrail by the plurality of rolling rollers 116. It is gradually stuck from the inside to the outside. Finally, the outer edge of the film Y is securely attached by the brush 117.

  In the present embodiment, in order to guide the contact bodies 122, 123 in the width direction of the handrail 12, the guide shaft 121 and the guide holes of the shaft support bodies 122B, 123B (through holes through which the guide shaft 121 is inserted) are used. In particular, the guide means is configured so that the abutments 122 and 123 are linearly translated in the width direction by the guide means, so that the width dimension of the handrail 12 is flexible and high. It can correspond to accuracy.

  In addition, in order to regulate the movement of the pair of contact bodies 122 and 123, a pair of racks 122C and 123C that are disposed to face each other, and a gear that is disposed between the pair of racks and meshes with the pair of racks together. 124 is provided, and this movement restricting means reverses the movement directions of the pair of contact bodies 122 and 123 in the width direction, and makes the movement amount the same. Since the positional relationship in the width direction between the apparatus main body and the handrail 12 can always be constant, positioning in the width direction of the apparatus 100 with respect to the handrail 12 can be facilitated, and the positioning accuracy can be increased. .

  Instead of the gear 124, a gear train formed by meshing a plurality of gears may be provided, and a pair of racks 122C and 123C may be meshed with any of the gears in the gear train. Good. For example, a first gear that meshes with one rack 122C and a second gear that meshes with the other rack 123C are provided, and an intermediate gear is meshed between the first gear and the second gear. Also good. In this case, the movement restricting means having the same function as described above can be configured even if the pair of racks are not arranged to face each other. For example, a pair of racks are arranged facing the same side, a first gear meshing with one rack and a second gear meshing with the other rack are provided, and the first gear and the second gear are provided. May be engaged with each other.

In this embodiment, the frame 201, the support rollers 202 and 204, the support shaft 205, the subframe 206, the main body positioning means 220 (the contact bodies 222 and 223, the contact rollers 222A and 223A, the shaft support bodies 222B and 223B, the rack 222C. , 223C, the gear 224, the support portions 225, 226, the elastic member 227), and the sticking roller 215 are basically the same as those described above except for the points described below.

  In the apparatus 200 of the present embodiment, the main body positioning means 220 is formed with roller surfaces 222A1 and 223A1 inclined upward on the contact rollers 222A and 223A. The contact rollers 222A and 223A have a rotation axis extending in a direction orthogonal to the extension direction of the handrail 12 (in the illustrated example, a direction orthogonal to the surface of the handrail 12). The roller surfaces 222A1 and 223A1 are configured in a conical shape centered on the rotation axis and directed obliquely upward. When the apparatus 200 is mounted on the handrail 12, the roller surfaces 222A1 and 223A1 of the contact rollers 222A and 223A are in contact with both 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 is also sandwiched in the vertical direction by the support rollers 202, 203, and 204 and the pair of contact rollers 222A and 223A. . As a result, the apparatus 200 is positioned in the width direction with respect to the handrail 12 by the elastic force of the elastic member 227, and at the same time, the apparatus 200 is held by the handrail 12 by the elastic force of the elastic member 227. It has become.

The operation member 231 can be selected to be drawn out to a position indicated by T in the drawing. For example, the operation member 231 can be pulled out when the operation handle 232 is rotated by a lever-type link structure or the like, and the operation member 231 can be released when the hand is released from the operation handle 232. Accordingly, the distance between the contact bodies 222 and 223 can be increased by operating the operation member 231 and pulling out one of the contact bodies 222 outward in the width direction, so that the apparatus 200 is easily set on the handrail 12. be able to. Here, when the operation member 231 is released, the apparatus 200 is automatically positioned in the width direction with respect to the handrail 12 by the elastic force of the elastic member 227.

  In this embodiment, an elastic member 209 such as a coil spring that presses the sticking roller 215 downward is provided. The elastic member 209 biases the sub frame 206 in a direction of rotating downward about the support shaft 205. Specifically, a support member 208 that pivotally supports the sub-frame 206 via the support shaft 205 is rotatably connected to the frame 201 via the support shaft 208s. 208 is urged downward by the elastic member 209. Therefore, the elastic force of the elastic member 209 urges the sub-frame 206 downward via the support member 208 and the support shaft 205, whereby the sticking roller 215 (and the finishing processing unit 217) is pressed against the handrail 12. become.

  Note that the handrail processing apparatus of the present invention is not limited to the illustrated examples described above, and it is needless to say that various modifications can be made without departing from the scope of the present invention. For example, although each said embodiment is comprised as a film sticking apparatus for sticking the film Y to the handrail 12, this invention is not restricted to such an apparatus, For example, the surface of the handrail 12 is used. The present invention can be applied to various processing devices such as a cleaning device for cleaning, a sterilization device for sterilizing the surface of the handrail 12 and a coating device for forming a predetermined coating film on the surface of the handrail 12. Further, the movement restricting means is not limited to the mechanism composed of the rack and the gear, but is connected to, for example, a mechanism using a gear train composed of a plurality of gears instead of the gear, or a pair of contact bodies. A pair of fluid pressure cylinders provided with the pistons arranged in opposite directions in the width direction, a fluid chamber defined on the rod side of one fluid pressure cylinder of the pair of fluid pressure cylinders; The fluid chamber on the opposite side of the rod of the other fluid pressure cylinder is communicated with the fluid chamber on the opposite side of the rod of one fluid pressure cylinder and the fluid chamber on the rod side of the other fluid pressure cylinder. Various mechanisms such as a cylinder connecting mechanism can be used.
