Problems solved by technology

Since the entire canvas is pulled from the side of the water tank away from the mold, the sliding part that is easy to slide and has a low-friction surface is pulled out with a small tension, and a large tension is required to pull out the driving part that is difficult to slide, so each canvas The contact resistance of the part makes a difference
Due to the difference in pull-out tension, there is a problem that the width of the entire canvas is narrowed by sliding the fabric toward the inside, and the predetermined shape of a C-shaped cross section cannot be maintained.

Embodiment approach 1

[0037] figure 1 is a side view showing the overall structure of the passenger conveyor, figure 2 It is a side view showing the structure of the handrail driving device. Next, as an example of a passenger conveyor, the structure of an escalator used for moving between upper and lower floors will be specifically described, and descriptions of other examples such as moving walkways will be omitted.

[0038] exist figure 1 , figure 2 Among them, the number 1 is the truss of the escalator erected between the upper and lower floors. The self-weight and loading load of the escalator are supported by the truss 1 . Label 2 is the step that passengers take when moving between the upper and lower floors; label 3 is the ring-shaped step chain connected with step 2; label 4 is the step drive sprocket with the step chain 3 around; label 5 is used for The driving motor that drives the step drive sprocket 4, etc.; the number 6 is a reducer that decelerates the output of the drive motor...

Embodiment approach 2

[0063] Figure 12 It is a sectional view which shows the structure of the belt of the manufacturing apparatus of the moving handrail for passenger conveyors concerning Embodiment 2 of this invention.

[0064] The guide belt 32 in Embodiment 2 is a cloth with a double-layer structure consisting of the lower layer 32a, which is made of the same material as the sliding cloth 20 of the canvas 18 and has a lower layer 32a on the lower surface side in contact with the mold 27. and the upper layer 32b, which is made of the same material as the base cloth 19 (product) of the canvas 18 and has high friction properties on the upper surface in contact with the lower surface (product) of the central part of the base cloth 19 of the canvas 18. base cloth composition.

[0065] Thereby, sliding between the product and the guide belt is difficult, and sliding between the mold 27 and the guide belt 32 is easy, and stable molding can be realized.

Abstract

The present invention obtains a manufacturing device for a movable handrail for a passenger conveyor, which can make the contact resistance of the surface in contact with the mold the same even if it is a plurality of canvases with different friction characteristics. The movable handrail for a passenger conveyor is provided with a main body resin part formed in an annular shape and having a C-shaped cross section, and a canvas provided on the inner side of the main body resin part along the long side of the main body resin part, and the canvas is provided with a sliding cloth and a sliding cloth provided on the main body. A base fabric with a resin part and high friction characteristics. The sliding cloth is provided on the base fabric to cover a part of the surface of the base fabric and has lower friction characteristics than the base fabric. The manufacturing device is equipped with a mold that makes the main resin part and the canvas Integrated molding; an extruder that extrudes the movable handrail molded through the mold; and a guide belt that is configured in the mold to contact the lower surface of the center portion of the base cloth with high friction characteristics and has the same low friction as the sliding cloth. Frictional properties and formed into a ring shape, the ring-shaped guide strip is extruded from the mold together with the canvas.

Description

technical field [0001] The present invention relates to a manufacturing device of a moving handrail for a passenger conveyor used in a passenger conveyor such as an escalator or a moving sidewalk. Background technique [0002] In a passenger conveyor called an escalator or a moving walkway, a ring-shaped moving handrail is generally used, and the cross section of the moving handrail is C-shaped. The moving handrail is a part for passengers on the steps to grasp for safety, it is driven in synchronization with the steps, and its travel is guided by means of guide rails or the like. [0003] In the passenger conveyor provided with the moving handrail configured as described above, the driving of the moving handrail and the guidance of running are generally performed via the inner surface of the moving handrail (canvas provided on the inner surface). Therefore, the inner surface of a moving armrest is required to have two functions: high friction characteristics (coefficient o...
