Description

  The present invention relates to a method for processing a moving handrail used on a man conveyor such as an escalator or a moving sidewalk.

  In a man conveyor such as an escalator or a moving sidewalk, an endless moving handrail is generally used. This moving handrail is for a passenger on the step to grasp for safety and is driven to synchronize with the step.

  The main part of the moving handrail is composed of, for example, a main body resin part, a tensile body, a canvas, and the like. The tensile body is incorporated in the main body resin portion in order to give a predetermined tensile strength to the moving handrail. That is, when an elongated handrail body is processed endlessly (endless processing), the function of the tensile body must be maintained even in the processed portion (joint portion).

The following Patent Document 1 discloses a detailed method for processing a long handrail main body into an endless shape.
Specifically, first, the resin above the tensile body is removed from the end of the long handrail main body. Next, the resin portion including the tensile body and the resin portion located below the tensile body are processed into a complicated uneven shape, and both ends are fitted into each other. And after supplementing the additional resin member (the exchange sheet 158 and the exchange top cap 160 in patent document 1) for supplementing the removed resin, and fitting the edge parts of a handrail main body, it heats using a predetermined type | mold. Perform molding.

Japanese Patent No. 3512234

  In the thing of patent document 1, in order to process each edge part of a handrail main body into the shape which mutually fits, the resin above the tensile body is removed and the tensile body is exposed. That is, when performing heat molding by fitting both ends of the handrail body, an additional resin member for supplementing the removed resin is required.

  If an additional resin member is used in the endless processing of moving handrails, the number of joints will increase, making it easier to peel off after molding, or covering the joint with an adhesive cover material to prevent peeling, etc. There was a problem such as needing treatment. In the thing of patent document 1, in order to prevent the peeling after joining, each edge part of a handrail main body is processed into the uneven | corrugated complicated shape, However, such a process requires a great deal of labor and time. It becomes necessary and work efficiency will fall remarkably.

  Moreover, in the thing of patent document 1, the said additional resin member appears on the surface of a moving handrail after an endless process. In reality, it is difficult to make the color of the additional resin member completely coincide with the color of the surface of the handrail body. In the case of the one described in Patent Document 1, the color of the joint portion does not match the color of the other portion. There was a problem that. In addition, since a moving handrail also enters into the field of view of the person around the man conveyor and moves, the difference becomes very noticeable if a part of colors are different. That is, the use of the additional resin member in the endless processing has been a major factor for reducing the design of the man conveyor.

  The present invention has been made to solve the above-described problems, and has as its object to endlessly and easily end the handrail body in a short time without requiring an additional resin member and without impairing the function as a moving handrail.

The main body resin portion 8 is made of, for example, a thermoplastic resin such as polyurethane. 2 shows a case where the main body resin portion 8 has a two-layer structure of a surface layer and an inner layer, the configuration is not limited to that shown in FIG. For example, the inner layer may be composed of a plurality of types of resin layers in accordance with the function to be given to the moving handrail 3.

  The canvas 9 is provided to reduce running resistance (sliding resistance) when the moving handrail 3 runs on a guide rail (not shown). The canvas 9 is formed of, for example, a woven or knitted fabric made of polyester or nylon fiber, and is disposed in a portion that can come into contact with the guide rail. Specifically, the canvas 9 is provided along the length of the main body resin portion 8 on the inner surface of the main body resin portion 8 having a substantially C-shaped cross section.

  The tensile body 10 is for imparting a predetermined tensile strength to the moving handrail 3 and preventing its elongation. The tensile body 10 is made of, for example, a steel wire rope, a steel tape, or the like, and is provided inside the main body resin portion 8 along the length thereof.

  FIG. 3 shows an example of a tensile body 10 suitable for manufacturing the handrail body 7 by extrusion molding. In FIG. 3, 11 is a wire rope, 12 is a fixing resin excellent in weldability with the resin body 8 (resin), and 13 is an adhesive for bonding and fixing the fixing resin 12 to the wire rope 11. . FIG. 3 shows a state before being incorporated in the main body resin portion 8 (before extrusion molding), and the wire rope 11 is entirely covered with the fixing resin 12. By using the tensile body 10 having such a configuration, the fixing resin 12 can be easily welded to the main body resin portion 8 at the time of extrusion molding, and the wire rope 11 is integrated with the main body resin portion 8. It becomes possible to fix firmly.

  And after manufacturing the elongate handrail main body 7 which has the said structure, the handrail main body 7 is cut | disconnected to desired length, and each edge part of the handrail main body 7 is processed. Specifically, one end of the handrail body 7 is processed into the state shown in FIG. 4, and the other end of the handrail body 7 is processed into the state shown in FIG.

6 and 7 schematically show the states shown in FIGS. 4 and 5. In FIG. 6 and FIG. 7, detailed description of the cross section of the handrail body 7 is omitted for easy understanding of the drawings. Each of FIG. 6A and FIG. 7A is a plan view, FIG. 7B is a side view, and FIG. 7C is a bottom view.
In the following, the state when the passenger on the step 2 grabs the moving handrail 3 (the state shown in FIG. 2) is used as a reference. Various explanations will be given with the side up.

In processing each end portion of the handrail body 7, first, the upper surface 14 for joining, the upper one end surface 15 for joining, and the lower one end surface 16 for joining are formed on one end portion of the handrail body 7.
The bonding upper surface 14 is formed of an upward plane formed at a position above one end of the tensile body 10. Specifically, using a blade (not shown) or the like, the resin of the main body resin portion 8 above the tensile body 10 is removed along the tensile body 10 from one end portion of the handrail main body 7. Thus, the upper surface 14 for bonding, in which one end portion of the tensile body 10 is disposed below, is formed.

  Further, the upper end surface 15 for bonding is formed as an obliquely upward plane extending upward from the upper surface 14 for bonding, and is inclined with respect to both the vertical direction and the width direction (left and right direction in FIG. 2) of the handrail body 7. Is provided. The upper end surface 15 for bonding is formed upward from the rear edge 14a of the upper surface 14 for bonding so as to have an inclination of 45 ° with respect to the vertical direction and the width direction of the handrail body 7, for example. ing.

  Further, the lower end surface 16 for bonding is formed of an obliquely upward plane extending downward from the upper surface 14 for bonding, and is similar to the upper end surface 15 for bonding in both the vertical direction and the width direction of the handrail body 7. It is provided to be slanted. The lower end surface 16 for bonding is formed downward from the end side edge portion 14b of the upper surface 14 for bonding so as to have an inclination of 45 ° with respect to the vertical direction and the width direction of the handrail body 7, for example. Has been.

  The formation order of the upper surface 14 for bonding, the upper one end surface 15 for bonding, and the lower one end surface 16 for bonding is appropriately determined from the ease of processing. For example, the lower end surface 16 for joining is first formed by diagonally cutting one end portion of the handrail body 7 with a blade. Then, after forming the upper end face 15 for joining by obliquely cutting from above the handrail body 7 until it contacts the tensile body 10, the cutting tool is moved along the tensile body 10, and the upper surface 14 for joining is moved. Form.

In addition, after forming the lower one end face 16 for joining, the edge processing of the canvas 9 on the one end side of the handrail body 7 is performed.
Specifically, as shown in FIG. 8, first, one end of the canvas 9 disposed at the edge of the lower end face 16 for joining is pushed into the main body resin part 8 in the vicinity, and one end of the canvas 9 is moved to the handrail main body. Bend to the inside of 7. This processing is performed while melting a part of the main body resin portion 8 by using, for example, a heated tool. Then, after bending the entire end portion of the canvas 9 inward, the end portion of the handrail body 7 is filled with a predetermined fastening resin 17a so as to cover one end of the canvas 9, and the end portion of the canvas 9 is connected to the main body resin portion. Fix to 8.

  In addition, after the lower end surface 16 for bonding is formed, both end portions of the lower end surface 16 for bonding that are substantially C-shaped (that is, both ear portions of the handrail main body 7 that forms a downward opening) are formed. The attachment hole 18a (first attachment hole) is formed along the length of the handrail body 7.

On the other hand, a predetermined process before molding is performed on the other end portion of the handrail main body 7 as well as the one end portion side. Specifically, a lower surface 19 for bonding, an upper other end surface 20 for bonding, and a lower other end surface 21 for bonding are formed on the other end portion of the handrail body 7.
The lower surface 19 for joining consists of the downward plane formed in the lower position of the other end part of the tensile body 10. FIG. Specifically, by using a blade or the like to remove the resin of the main body resin portion 8 below the tensile body 10 along the tensile body 10 from the other end portion of the handrail main body 7, The joining lower surface 19 on which the other end of the tensile body 10 is disposed is formed.

  The other upper end surface 20 for bonding is formed as an obliquely downward plane extending upward from the lower surface 19 for bonding, and is provided so as to be inclined with respect to both the vertical direction and the width direction of the handrail body 7. The upper other end surface 20 for bonding is formed upward from the end side edge portion 19a of the lower surface 19 for bonding so as to have an inclination of 45 ° with respect to the vertical direction and the width direction of the handrail body 7, for example. ing.

  Further, the lower other end surface 21 for bonding is formed as a diagonally downward plane extending downward from the lower surface 19 for bonding, and is provided so as to be inclined with respect to both the vertical direction and the width direction of the handrail body 7. The lower other end surface 21 for bonding is formed downward from the rear edge 19b of the lower surface 19 for bonding so as to have an inclination of 45 ° with respect to the vertical direction and the width direction of the handrail body 7, for example. Has been.

  The bonding upper other end surface 20 and the bonding lower other end surface 21 are provided corresponding to the bonding upper one end surface 15 and the bonding lower one end surface 16 formed on one end portion side of the handrail body 7. . That is, when the one end and the other end of the handrail body 7 are arranged in a straight line in a state in which the lower surface 19 for bonding is aligned (contacted) with the upper surface 14 for bonding, the upper upper end surface 15 for bonding and the bonding upper end surface 15 are bonded. The other upper end surface 20 is disposed opposite to and parallel to each other. Similarly, the lower one end surface 16 for bonding and the lower other end surface 21 for bonding are arranged opposite to each other and in parallel.

  In addition, the formation order of the said lower surface 19 for joining, the other upper end surface 20 for joining, and the lower other end surface 21 for joining is suitably determined from easiness of a process, etc. It forms from any surface if possible. It doesn't matter.

Moreover, after forming the said lower side other end surface 21 for joining, the edge part process of the canvas 9 of the other end part side is performed by the procedure similar to the one end part side of the handrail main body 7. FIG.
Specifically, first, the other end of the canvas 9 arranged at the edge of the lower other end surface 21 for joining is pushed into the main body resin portion 8 in the vicinity, and the other end portion of the canvas 9 is brought into the inner side of the handrail main body 7. Bend it. And after bending the other end part of the canvas 9 inwardly, the other end part of the handrail main body 7 is filled with the fastening resin 17b so as to cover the other end of the canvas 9, and the other end part of the canvas 9 is connected to the main body. Fix to the resin part 8.

In addition, after forming the lower other end surface 21 for bonding, both ends of the lower other end surface 21 for bonding which are substantially C-shaped (that is, both ears of the handrail main body 7 forming a downward opening) are formed. A mounting hole 18b (second mounting hole) is formed along the length of the handrail body 7.
The attachment holes 18b are provided corresponding to the attachment holes 18a formed on one end portion side of the handrail body 7. That is, when the one end part and the other end part of the handrail body 7 are arranged in a straight line with the joining lower surface 19 aligned (contacted) with the joining upper face 14, the attachment hole 18a and the attachment hole 18b are Are arranged in a straight line so as to face each other.

  After both end portions of the handrail main body 7 are processed according to the above-described procedure, an operation of joining both end portions of the handrail main body 7 is performed.

Specifically, as shown in FIGS. 9 to 11, one end and the other end of the handrail body 7 are overlapped and arranged in a straight line, and this end portion is installed in a predetermined mold 22. To heat mold. When the handrail body 7 is installed in the mold 22, the bonding upper surface 14 and the bonding lower surface 19, the bonding upper one end surface 15 and the bonding upper other end surface 20, and the bonding lower end surface 16 are bonded. It arrange | positions so that the use lower side other end surface 21 may each overlap (contact).
Further, when the handrail body 7 is installed in the mold 22, the short end tensile body 23 is inserted into the mounting hole 18 a and the mounting hole 18 b. That is, the end tensile member 23 is built in the ear portion of the handrail body 7 so that the steel member straddles between one end and the other end of the handrail body 7.

  The molding die 22 has a function of molding the joint portion of the handrail body 7 into the same outer shape as the intermediate portion thereof, and the main parts thereof are, for example, a lower die 24, a middle die 25, an upper die 26, a fixed A bolt 27 is used. The middle mold 25 and the upper mold 26 are provided with reservoirs 25 a and 26 a whose openings are opposed to the inner side surface and the lower surface of the handrail body 7 at a portion disposed above the joint portion of the handrail body 7. The reservoirs 25a and 26a are portions where excess resin is pushed out and collected during molding.

  In addition, the end tensile body 23 is, for example, the same in cross section as shown in FIG. 3 in order to ensure fixation to the main body resin portion 8 after molding. That is, the end tensile member 23 is provided with a wire rope (steel member) having a predetermined length, and this wire rope is covered with the fixing resin over the length thereof.

  In addition, since the tensile body 10 is provided in the one end part and other end part of the handrail main body 7, respectively, only the one end part and other end part of the handrail main body 7 were piled up, and this overlapped. The thickness of the whole part becomes larger than the thickness of the other part (for example, intermediate part) of the handrail main body 7. That is, the overlapping portion is thicker than the other portion of the handrail body 7 by an amount corresponding to the thickness of the tensile body 10. For this reason, when one end and the other end of the handrail main body 7 are overlapped and installed on the mold 22, the lower mold 24 and the upper mold 26 cannot be accurately opposed and fixed. As shown in FIG. 12 (a), a slight gap 28 is formed between the mold 22 and the grip surface side at one end of the handrail body 7 and the lower surface side at the other end.

  Therefore, when joining the one end portion and the other end portion of the handrail body 7, after the handrail body 7 is installed in the mold 22, first, the handrail body 7 is heated by a method such as applying heat to the mold 22. The joining portion is heated to a predetermined temperature (for example, 150 to 200 ° C.). And after the junction location of the handrail main body 7 reaches the said predetermined temperature, the fixing bolt 27 is firmly fastened and the lower mold | type 24 and the upper mold | type 26 are match | combined, and the press molding with respect to the handrail main body 7 is performed. In addition, as described above, an extra resin corresponding to one stage of the tensile body 10 exists at the joint portion of the handrail body 7. For this reason, this excess resin is discharged into the reservoirs 25a and 26a during the pressure molding, and the joint portion of the handrail body 7 is molded into the same outer shape as the intermediate portion.

  Here, the end surfaces 15, 16, 20, and 21 at one end and the other end of the handrail body 7 are formed obliquely with a predetermined angle with respect to the vertical direction of the handrail body 7. The upper other end surface 20 for bonding and the lower other end surface 21 for bonding are connected to the upper one end surface 15 for bonding and the lower one end surface 16 for bonding when the handrail body 7 is installed in the mold 22. These are arranged so as to contact each other from above. For this reason, at the time of the above pressure molding, the other upper end surface 20 for bonding is pressed against the upper one end surface 15 for bonding, and the lower other end surface 21 for bonding is pressed against the lower one end surface 16 for bonding. By acting, it becomes possible to weld each end face reliably.

  Further, fastening resins 17 a and 17 b are attached to one end and the other end of the handrail body 7 so as to cover one end and the other end of the canvas 9. For this reason, when the joint part of the handrail main body 7 is heated and pressure-molded, each fastening resin 17a and 17b and each fastening resin 17a and 17b and the main body resin portion 8 are welded and bent inward. The resin is integrated so as to cover both ends of the canvas 9 (see FIG. 13). Therefore, each end portion of the canvas 9 can be firmly fixed to the main body resin portion 8, and the canvas 9 can be surely prevented from peeling off.

  In the bonded main body resin 7, a portion where the canvas 9 does not exist appears linearly at a position which is a boundary between the lower end surface 16 for bonding and the lower other end surface 21 for bonding. Therefore, in order to prevent the resin (fastening resins 17a and 17b) disposed between one end and the other end of the canvas 9 from coming into contact with the guide rail when used as the moving handrail 3, the resin at the portion is used. Is molded so that its surface is one step lower than the surface of the canvas 9 so as not to protrude outward from the surface position of the canvas 9.

  Then, after the press molding, when a predetermined time elapses and the temperature of the handrail body 7 decreases, the handrail body 7 is removed from the molding die 22 to remove excess resin from the joint portion. Each opening of the reservoirs 25a and 26a is disposed so as to face a portion that cannot be seen by the passenger when used as the moving handrail 3, that is, the inner side surface and the lower surface of the handrail main body 7. For this reason, the trace which arises by removing excess resin does not appear in the design surface of the moving handrail 3, and the beauty | look of the moving handrail 3 is not impaired.

  By the above, joining of the edge parts of the handrail main body 7 is completed, and the endless moving handrail 3 can be obtained.

  According to Embodiment 1 of this invention, when joining the edge parts of the handrail main body 7, additional resin members other than the handrail main body 7 are not required. For this reason, all the conventional problems which have arisen by using an additional resin member are eliminated. Moreover, the process of each edge part of the handrail main body 7 can be simplified, and the effort and time which joining requires can be reduced significantly.

  In addition, since the tensile body 10 is appropriately incorporated in the joint portion of the moving handrail 3 and is firmly welded to the main body resin portion 8, the tensile strength of the joint portion does not decrease. Furthermore, the joint strength of the ear | edge part of a junction part is fully securable by the edge part tension body 23 incorporated at the time of joining.

  In addition, each end surface 15, 16, 20, 21 at the end of the handrail body 7 is formed obliquely with a predetermined angle with respect to the width direction of the handrail body 7. That is, the boundary between the upper one end surface 15 for bonding and the upper other end surface 20 for bonding and the boundary between the lower one end surface 16 for bonding and the lower other end surface 21 for bonding are the longitudinal direction of the handrail body 7 (the moving handrail 3 It is arranged obliquely with respect to (traveling direction). For this reason, when used as the moving handrail 3, the load acting on each boundary portion can be reduced, and the occurrence of peeling during traveling (particularly, peeling of the canvas 9) can be greatly reduced.

  In the present embodiment, the case where the upper one end surface 15 for bonding and the lower one end surface 16 for bonding are formed as an upward plane, and the other upper end surface 20 for bonding and the lower other end surface 21 for bonding are formed as a downward plane is described. However, the bonding upper end surface 15 and the bonding lower end surface 16 may be a downward plane, and the bonding upper other end surface 20 and the bonding lower other end surface 21 may be an upward plane. Even with this configuration, the same effects as described above can be obtained.
