Description

[Detailed Description of the Invention] This invention relates to a dust prevention device for a rail for suspending a traveling body, which is mainly used in a scanning movement mechanism such as a sensing section of a measuring instrument.

Measuring instruments such as thermometers, moisture meters, and scratch detectors can be used to measure the required characteristics of a material in a distributed or wide area by scanning and moving the sensitive part along the surface of the material under test. However, in such cases, a rail installed at a high place in the room is generally used to guide the reciprocating movement of the sensing section.

However, when rails are installed at high places indoors, dust that flies up from the floor or foreign matter emitted from the material comes into contact with the rails and easily stick to the surface of the rails. Coupled with the fact that it is difficult to clean the rails, over a long period of time foreign matter that accumulates on the rails grows into a large size and often falls onto the material.

By the way, depending on the type of material, there are cases where it is prohibited for foreign matter to get mixed into the material. For example, food materials cannot be allowed to get mixed in with foreign matter due to hygiene control, and paper-making materials can be damaged due to foreign matter mixed in. This caused holes in the product, making the product unusable.

The present invention has been developed to solve these problems, and the purpose of the present invention is to provide a system for suspending traveling bodies to prevent foreign matter from adhering to or accumulating on elevated rails. The purpose of the present invention is to provide a dust prevention device for rails.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

In the dust prevention device of the embodiment, as shown in FIGS. 1 and 2, a rail 5 made of engineered angle material is spanned between the lower ends of two mounting plates 6 hanging from the ceiling. The rail 5 is installed horizontally to protect the rail 5 from dust.

Thus, the running body 7, such as the sensing section, has Y-shaped support rods 8 erected on the upper surface of the central portion of both ends, and is pivoted to the upper end of each of the bifurcated ears 8a. A pair of orthogonal rollers 9 and 10 are
They abut against the side and top surfaces of the rail lower plate 5a, respectively, so that the traveling body 7 is suspended from the rail 5 and
It can be slid freely on the top.

The traveling body 7 is driven by a drive member (not shown) and reciprocates over the scanning distance on the rail 5 at a predetermined timing.

By the way, the rail 5 is wrapped in a long box-shaped duct 11, and the duct 11 has its upper surface fixed to a mounting plate 6 fixed to the ceiling at both ends, and also has a boat-shaped bottom plate. 1
1 The center line part of a is the slit through which the support rod 8 passes) 1
1b is truncated during the scanning distance.

In addition, on both sides of the lower surface of the bottom plate 11a near the center line,
A pair of rubber plates 12 are fully extended, and the slit openings at the portions where the support rod 8 does not penetrate are covered with the downward ends of the rubber plates 12 that are elastically polymerized. At the point where the rod 8 penetrates, the rubber plate 12 is distributed and a slight gap is created.

In addition, a suction fan 14 is attached to each opening at both ends of the duct 11 by means of radial support rods 13, and this fan 14 functions to maintain the internal pressure of the duct 11 at a positive pressure.

In the dust prevention device of the embodiment configured in this way, the support rod 8
Air is blown out from the slight slit gap in the penetration part to purge the air inside the duct 11, and as a result, foreign matter approaching the rail 5 is blown away by the purge airflow, so that the foreign matter does not adhere to the rail 5. Therefore, foreign matter does not accumulate on the rail 5 even without special cleaning.

It goes without saying that the present invention can be similarly applied to suspension rails having shapes other than those described above. For example, as shown in FIG. Even in the case of the rail 16 in which the parallel rail 16 is formed with an inward chevron-shaped tapered surface and this tapered surface is sandwiched between the rollers 18 and 19 of the traveling body support rod 17, the duct 20 in the same manner as described above is surrounded. If you do so, you can get the same dust prevention effect.

Here, instead of the rubber plate 12 for closing the slit in the configuration of the embodiment described above, a flocked member such as a brush may be used. In other words, any commonly used elastic flexible member can be widely used.

As described above, according to the dust prevention device for a rail for suspending a traveling body according to the present invention, the duct is surrounded by the rail and the air inside the duct is purged with air, so the purge airflow prevents foreign matter from reaching the rail. As a result, the rails are always kept clean, and as a result, the material that is acted upon by the running body is not disturbed, which has the effect of improving the environmental friendliness of the scanning operation.
