FIG. 1 is a diagram showing a handrail manufacturing apparatus for an escalator, and shows a state in which winding is started. The unwinding bobbin 1 is installed on the first table 9 with the handrail 20 wound around the first body portion 5, and the winding bobbin 3 is installed on the second table 19 without winding the handrail. Has been done. The handrail 20 is pulled out from the unwinding bobbin 1, passes through the guide roller 10 provided in the traverser 2 and the length measuring portion 11, and is provided in the fixed portion 18 provided on the second body portion 14 of the winding bobbin 3. It is fixed at a length of about 3 m from the tip of the. The tip of the handrail 20 is bound by the band 21 in a rolled state.

When the handrail 20 passes between the two guide rollers 10 provided on the traverser 2, the traverser 2 reciprocates from one to the other and from the other to the other in parallel with the axial direction of the take-up bobbin 3. By repeating the above steps, the feeding direction of the handrail 20 is controlled. By controlling the feeding direction of the handrail 20 by the traverser 2, the handrail 20 is fed once in one of the axial directions of the bobbin 3 with the handrail tip portion 38 fixed by the fixing portion 18 of the take-up bobbin 3 as a boundary. It is rolled up. Next, the handrail 20 is wound once while returning to the other side in the axial direction of the winding bobbin 3 with the handrail tip portion 38 fixed by the fixing portion 18 of the winding bobbin 3 as a boundary. After that, the handrail 20 alternately repeats the operation of winding while moving from one of the axial directions of the bobbin 3 to the other and from the other to the other. The handrail 20 is wound in order from the handrail tip 38 fixed to the take-up bobbin 3 toward one or the other in the axial direction. That is, the take-up bobbin 3 is wound in both axial directions of the take-up bobbin 3 with the handrail 20 as a boundary where the handrail 20 starts to be taken up.

It is not necessary to alternately repeat the operation of winding the handrail 20 while reciprocating from one of the axial directions of the winding bobbin 3 to the other and from the other to the other. In the above description, the handrail 20 is wound once while reciprocating from one of the axial directions of the take-up bobbin 3 to the other and from the other to the other. good. That is, the handrail 20 winds the handrail 20 in one of the axial directions of the winding bobbin 3 and the handrail 20 in the axial direction of the winding bobbin 3 with respect to a part of the handrail 20 fixed to the winding bobbin 3. It may include winding to the other, which is different from one.

The handrail 20 wound around the take-up bobbin 3 is cut to a predetermined length required for processing and joined to an annular endless structure. Therefore, the length measuring unit 11 provided in the traverser 2 measures the length from the tip of the handrail 20. The handrail 20 measured to a predetermined length is cut by the cutting portion 39.

FIG. 12 is a cross-sectional view showing a state in which the handrail according to the first embodiment of the present invention is joined to the annular endless structure. With respect to the handrail 20 wound up by the take-up bobbin 3, the handrail tip portion 38 of the handrail 20 from which the band 21 has been removed and the handrail end portion 40 of the handrail 20 cut to a predetermined length and taken out are They are butted against each other and are joined to an endless structure by a high temperature press or the like in the joining device 41.

The handrail 20 changes the joining method at both ends based on the number of times the winding bobbin 3 is wound in one axial direction and the number of times the handrail 3 is wound in the other axial direction. Specifically, when the end portion cut in a direction different from the originally wound direction is located with the handrail 20 in the portion extending from the portion fixed by the fixing portion 18 to the handrail tip portion 38 as a boundary. The outer surface of the handrail tip 38 and the outer surface of the cut handrail end 40 may be twisted and joined in the forward direction so as to first coincide with each other. Further, when the handrail end portion 40 cut in the same direction as the first winding direction is located with the handrail 20 of the portion from the portion fixed by the fixing portion 18 to the handrail tip portion 38 as a boundary. , The outer surface of the handrail tip 38 and the outer surface of the cut handrail end 40 may be twisted and joined in opposite directions so that they first coincide with each other. Here, if the number of times the handrail 20 is wound in one axial direction of the take-up bobbin 3 and the number of times the handrail is wound in the other axial direction of the take-up bobbin 3 are different a plurality of times, the handrail 20 depends on the number of times. 20 may be twisted in the forward direction or the reverse direction to join. As described above, the handrail 20 is based on the number of times the handrail 20 is wound in one axial direction of the winding bobbin 3 and the number of times the handrail 20 is wound in the other axial direction of the winding bobbin 3. By changing it, it can be processed into an annular shape without twisting.

FIG. 13 is a diagram showing an operation of storing the handrail in the container according to the first embodiment of the present invention. As shown in FIG. 13A, the take-up bobbin 3 around which the handrail 20 joined to the endless structure is wound is removed from the second table, and the axial direction thereof is adjusted to be the vertical direction, such as a cardboard box. It is held on the shipping container 42. Next, as shown in FIG. 13B, the second flange portion 13 on the container 42 side is removed. Next, as shown in FIG. 13 (c), the second body portion 14 of the take-up bobbin 3 around which the handrail 20 is wound moves toward the container 42. Here, as shown in FIG. 13D, the body diameter of the second body portion 14 may be slightly changed. As a method for slightly changing the body diameter of the second body portion 14, for example, there is a three-claw chuck method in which a work is clamped by a processing machine such as a lathe. The method for slightly changing the body diameter of the second body portion 14 is not limited to the above. By reducing the body diameter of the second body portion 14, a gap is created between the second body portion 14 and the wound handrail 20, and the handrail 20 is easily removed. Next, as shown in FIG. 13 (e), the second body portion 14 is moved in the vertical direction and removed from the handrail 20. Of the handrail 20, the portion of the handrail 20 that protrudes without being stored in the container 42 is stored after being made into a ring having a diameter that can be stored in the container 42, or is stored after being made into a ring having a size that can be stored in advance. By the above operation, the handrail 20 is housed in the container 42 as shown in FIG. 13 (f).

By moving the handrail 20 joined to the endless structure together with the second body 14 of the winding bobbin 3 toward the container 42, it is not necessary to crawl the handrail 20 on the floor, and the packing work is performed. You can save time. In addition, the skill level of the operator required for storing the large annular handrail 20 crawled on the floor in the container 42 becomes unnecessary.

The handrail 20 stored in the container 42 becomes one ring without kinking when unpacked at the site or the like. In this state, it is assembled as a product on the balustrade of the escalator.

As described above, in the method for manufacturing an escalator handrail according to the first embodiment of the present invention, a predetermined length is taken out from a strip-shaped resin molded body previously wound around a first winding frame, and both ends thereof are joined. This is a method for manufacturing an escalator handrail, in which a part of a strip-shaped resin molded body wound around the first winding frame is supported so as to be wound around the second winding frame. The step of winding the strip-shaped resin molded body in one of the axial directions of the second winding frame for the supported part, and the step of winding the strip-shaped resin molded body for the supported part. Includes a different step of winding to the other and a step of joining both ends of the wound strip-shaped resin molded body, based on the number of times it is wound on one and the number of times it is wound on the other. Change the joining method. As a result, the handrail 20 is not dragged by being crawled on the floor, so that the decorative surface of the handrail 20 is not damaged by the floor or surrounding devices.

Further, when the handrail 20 passes through the guide roller 10, the traverser 2 repeats the operation of reciprocating from one side to the other side and from the other side to the other side in parallel with the axial direction of the take-up bobbin 3. The handrail 20 is wound in both axial directions of the winding bobbin 3 with the winding start point as a boundary. By storing the handrail in the container 42 in this state, the handrail wound for several turns can be made into one ring without twisting at the time of unpacking.

Since the handrail 20 is wound around the take-up bobbin 3, when joining both ends of the handrail 20 to the endless structure, the handrail 20 does not crawl on the floor, and the space for joining work should be saved. Can be done. Further, since the length measuring unit 11 measures the length of the handrail 20 unwound from the unwinding bobbin 1, it is possible to save the trouble of performing the length measuring work with the handrail 20 crawling on the floor.
