Abstract

PURPOSE: To provide an application method of coating to a man conveyor handrail enabling almost uniform fine coating in a short time. CONSTITUTION: Sponge like porous material 10 is enclosed in a storage case 9. A coating is absorbed into this porous material 10, and the porous material 10 is brought into pressure contact with the upper plane part 1a of a handrail 1. In this state, the storage case 9 is slided along the handrail 1 so as to form the coat and film of almost uniform coating on the upper plane part 1a of the handrail.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating method for coating a man conveyor handrail.

[0002]

2. Description of the Related Art Generally, a man conveyor handrail for an escalator or an automatic line is disclosed in Japanese Patent Laid-Open No. 58-78983.
As shown in Japanese Patent Publication, the roller is pressed against the roller and driven while being bent, and because the user also uses it while being caught by it, dirt such as hand marks is accumulated by the user's hand and the surface gloss Or the surface of the handrail is hardened by stress of temperature and humidity for a long period of time, and as a result, cracks occur and the appearance design is impaired.

In the conventional glaze regeneration of the surface of the handrail, after polishing the surface of the handrail, as shown in FIG. 5, a coating agent 8 such as silicone or acrylic solvent is applied by a spray gun 4 using a compressor or the like. I was going.

[0004]

However, in the conventional glazing method, when the man conveyer is installed as urban traffic such as a subway, since the air flow near the man conveyer is strong, the coating agent 8 is applied by the spray gun 4. When a small particle is sprayed into the air flow, only the large particle 8a drops on the handrail 1 to form a drop mark 8b. In many cases, a beautiful coating could not be made.

It is an object of the present invention to provide a coating method for a man conveyor handrail, which is capable of performing a beautiful coating substantially uniformly in a short time.

[0006]

In order to achieve the above object, the present invention provides a coating agent for a man conveyor handrail in which a coating film is formed on an upper flat surface portion of the man conveyor handrail. Is absorbed, and the coating agent is applied to the upper flat surface portion of the man conveyor handrail with this porous material to form the coating film.

[0007]

In the coating method for coating the man conveyor handrail according to the present invention, the coating material is applied to the upper flat surface portion of the man conveyor handrail by using the porous material having absorbed the coating material as described above. Even in a place with a strong air flow, a clean coating can be performed almost uniformly in a short time without causing a small portion of the particles of the coating agent to be blown off and without forming a drop mark due to the large particles.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a side view showing a drive system of a man conveyor handrail adopting a coating method for a man conveyor handrail according to an embodiment of the present invention. The endless handrail 1 is driven by a drive pulley 2 and is rotationally driven along a guide roller 3. FIG. 4 is an enlarged cross-sectional view of the handrail 1 shown in FIG. 3, in which the upper flat portion 1a contacts the guide roller 3, and when it is used for a long period of time, it becomes dirty due to the user's hands, etc. Then, the guide roller 3 is flattered, and this dirt is present on the entire circumference of the upper flat surface portion 1a of the handrail 1 and spreads the stain, so that the gloss is lost.

Therefore, as shown in FIG. 1, a sponge-like porous material 10 is housed in a housing case 9, the coating material 8 is absorbed by the porous material 10, and the upper flat surface of the handrail 1 is covered. When the storage case 9 is slid along the handrail 1 under pressure contact with 1a, a substantially uniform coating and film are formed on the upper flat surface portion 1a of the handrail 1. At this time, on the upper flat surface portion 1a of the handrail 1, sliding streaks 8c are formed by the coating agent 8 immediately after coating, as shown in FIG.
During a predetermined drying time, it is fluidized and smoothed, and eventually becomes a mirror-like surface to be dried.

Since the coating material 8 is applied to the upper flat surface portion 1a of the handrail 1 by the porous material 10 which has absorbed the coating material 8 as described above, the coating material 8 can be applied to the upper flat surface portion 1a of the handrail 1 as in the conventional case. A neat coating can be performed without the small part of the particle being blown off and without forming a dent drop trace due to the large particle. Further, unlike the conventional case, a large-scale device is not required, so that beautiful coating can be performed in a short time.

FIG. 6 shows an upper plane portion 1a of the handrail 1.
It is sectional drawing of a handrail part which shows the state after apply | coating the coating agent 8 to FIG. The handrail 1 is slidably held by the guide rail 1b supported by the deck 15. After applying the coating agent 8 to the upper flat surface portion 1a of the handrail 1, the decks 1 on both sides of the handrail 1
5, the suction arm 11 is vacuum-sucked to fix the holding arm 12, and the vinyl 13 is disposed between the paired holding arms 12 so as to cover the upper flat surface portion 1a of the handrail 1,
The vinyl 13 is fixed by a magnet 14 which is attracted to the holding arm 12 from above the vinyl 13.

The cover cover 16 thus constructed
Is provided so as to cover the upper flat surface portion 1a of the handrail 1 after the coating agent 8 is applied. Therefore, until the coating agent 8 on the handrail 1 is dried, abrasive powder, dust, etc. do not adhere to the same portion. The coating film after drying becomes even cleaner. When the drying time is shortened, the cover arm 16 is formed by covering the outer periphery of the handrail 1 with the holding arm 12 and the vinyl 13 almost completely, and warm air is blown into the cover cover 16 to cool regions such as cold regions. But it works.

[0013]

As described above, according to the method for coating a man conveyor handrail according to the present invention, a porous agent containing a coating agent is used to coat the handrail. It is possible to form a uniform coating film without unnecessary scattering of the agent and to polish the design surface neatly.
