Problems solved by technology

Therefore, the concavo-convex shape of the tooth shape cannot be formed by this extrusion process. Although it is considered to cut the formed moving handrail in another process, or to re-form it by reheating, both of them need to be processed at different times. Two processes are performed, so there is a problem that hinders productivity

Embodiment 1

[0033] Fig. 1 is a diagram showing a manufacturing apparatus for a moving handrail of a passenger conveyor according to Embodiment 1 of the present invention.

[0034] In FIG. 1 , a raw material of thermoplastic resin, which is a main material of a moving handrail, is loaded from a material loading port 2 of a molding machine 1 .

[0035] The raw material loaded from the material loading port 2 is heated and mixed by the heater present in the molding machine 1, and then extruded from the extrusion port 4 by the extruder 3, and extruded as a material that has become approximately in the shape of a moving handrail. The moving handrail blank 5 of the above-mentioned thermoplastic resin.

[0036] Fig. 2 is a sectional view along line F-F of the handrail blank 5 of the passenger conveyor according to Embodiment 1 of the present invention. At the moment when the moving handrail blank 5 is extruded, the tooth profile has not yet been formed.

[0037] In the case where the moving ha...

Embodiment 2

[0050] Embodiment 2 describes the case of a manufacturing apparatus for manufacturing a handrail by joining previously formed rack-shaped blanks in a temperature range in which the handrail blanks are plastically deformable.

[0051] Fig. 6 is a diagram showing a manufacturing apparatus for the moving handrail 9 of the passenger conveyor according to the second embodiment of the present invention. In addition, parts not shown are the same as those in Embodiment 1, and the same reference numerals in FIG. 6 as those in FIG. 1 indicate the same or corresponding parts.

[0052] In Fig. 6, the raw material loaded from the material loading port 2 is heated and mixed by the heater present in the molding machine 1, and then extruded from the extrusion port 4 by the extruder 3, and the extruded product becomes The above-mentioned thermoplastic resin moving handrail blank 10 is substantially in the shape of a moving handrail.

[0053] Fig. 7 is a sectional view along line G-G of the mo...

Embodiment 3

[0062] Embodiment 3 describes the case of a manufacturing apparatus for manufacturing a handrail by bonding a preformed rack-shaped material and a handrail material.

[0063] Fig. 10 is a diagram showing an apparatus for manufacturing a moving handrail of a passenger conveyor according to Embodiment 3 of the present invention. In addition, the parts not shown are the same as those in Embodiment 2, and the same reference numerals in FIG. 10 as those in FIG. 6 indicate the same or corresponding parts.

[0064] In Fig. 10, the raw material loaded from the material loading port 2 is heated and mixed by the heater present in the molding machine 1, and then extruded from the extrusion port 4 by the extruder 3, and the extrusion becomes The above-mentioned thermoplastic resin moving handrail blank 10 is substantially in the shape of a moving handrail.

[0065] Fig. 11 is a structural view showing a rack-shaped blank 13 as a material at the time of manufacture of a manufacturing appa...

Abstract

To reduce wear of a movable scroll or the like generated when HFCs refrigerant not containing chlorine and of poor wear resistance characteristics or natural refrigerant such as CO2 of which use pressure is high is used or when a machine is operated at high load. In a sliding part surface of the movable scroll 3, anodic oxidation layer 36 of improved surface roughness is provided on a surface layer of the sliding surface of the movable scroll by removing a predetermined thickness from the sliding part surface after anodic oxidation treatment process. Consequently, a fluid machine of which movable part is light and of which sliding part is excellent in wear resistance is provided easily at low cost.

Description

technical field [0001] The present invention relates to a manufacturing device and a manufacturing method of a moving handrail of a passenger conveyor. Background technique [0002] In existing passenger conveyor devices, the power of the driver is used to drive the movement of the steps. In addition, the driving method of the ring-shaped moving handrail that rotates in the same direction as the steps is generally to press and hold the back side and the surface side of the moving handrail by a pair of rollers, the driving roller and the backup roller, and use the force transmitted from the driver. The power of the above-mentioned pair of rollers drives the driving roller on the back side of the moving handrail to rotate, so that the moving handrail turns at the same speed as the steps by means of frictional force and rotational drive due to pressurization. [0003] In the general driving method of the above-mentioned moving handrail, the moving handrail is pressed and clamp...
