  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a main part of the guide rail oiling device according to the first embodiment of the present invention before the magnet is mounted, and FIG. 2 is a schematic plan view of the guide rail oiling device.

  The oil supply device for guide rail 7 is attached to a location that moves up and down in conjunction with an elevator car (not shown) and stores a lubricating oil tank 5 that stores lubricating oil 2 (see FIG. 6), and a lubricating oil 2 The oil supply unit 4 that is impregnated and slidably contacts the guide surface 3a of the guide rail 3 of the elevator to apply the lubricant, and one end is immersed in the lubricant 2 in the lubricant tank 5 and the other end contacts the oil supply unit 4. The sheet-like lubricating oil supply member 6 that sucks up the lubricating oil 2 in the lubricating oil tank 5 and replenishes it to the oil supply unit 4 is mainly configured.

  As shown by the dotted line in FIG. 2, the oil supply unit 4 is in sliding contact with the three guide surfaces 3a (see FIG. 1) provided on the guide rail 3, and applies the lubricating oil 2 to each guide surface 3a. The planar shape is substantially concave.

  The oil supply unit 4 is supported by the heads of the plurality of support bases 14 so as to be higher than the display column 13 indicating the oil level height indicating the maximum amount of lubricating oil stored. The structure does not directly contact the lubricating oil in the tank 5.

  The lubricating oil supply member 6 has a fine hollow structure such as wool, gauze, and non-woven fabric. The lubricating oil 2 stored in the lubricating oil tank 5 by the capillary action of the lubricating oil supply member 6 is supplied to the oil supply unit. 4 is supplied to the guide surface 3 a of the guide rail 3 through the guide 4. As a result, the frequency of oil supply to the guide rail oil supply device 7 is greatly reduced.

  As shown in FIG. 2, a magnet 9 is installed in the lubricating oil tank 5. And the iron powder 8 (refer FIG. 6) contained in the lubricating oil 2 which reflows in the lubricating oil tank 5 is made to adsorb | suck to the magnet 9, and the magnet 9 is periodically taken out from the lubricating oil tank 5, and the iron powder 8 Then, the magnet 9 is returned to the lubricating oil tank 5 again to prevent the iron powder 8 from accumulating at the bottom of the lubricating oil tank 5, and the cleaning of the lubricating oil tank 5 can be simplified.

  The type of the magnet 9 may be a permanent magnet or an electromagnet, but a permanent magnet with a simple configuration and low cost is desirable. Although the magnet 9 may be used alone, for example, when it is housed and installed in a thin packaging member (including a container, a bag, and a sheet material) that is made of synthetic resin and can be unpacked and reused, the iron powder 8 is packed. Although it is adsorbed on the surface of the member, if the magnet 9 is taken out from the unpacking member and the magnet 9 is taken out, the iron powder 8 is easily detached from the surface of the packing member. Good sex.

  In the present embodiment, a thin packaging member that can be unpacked and reused is used, but it is also possible to use a disposable packaging member that is not reused.

  The iron powder 8 is mainly reflowed and settled in the locations A, B, C located below the oil supply unit 4 having a substantially concave planar shape as shown in FIG. If 9 is installed at three locations A, B and C, the adsorption efficiency of iron powder 8 is good.

  Moreover, if the magnet 9 is disposed only at one location A in the middle and the magnet 9 is slid to locations B and C, the iron powder 8 that has settled at locations B and C can be adsorbed. Therefore, the magnet 9 may be arranged in one place.

  FIG. 3 is a schematic plan view of a guide rail oiling device 7 according to a second embodiment of the present invention. In the present embodiment, a magnet 9 having a substantially concave planar shape along three locations A, B, and C is installed. In this way, the trouble of sliding the magnet 9 can be saved, the number of parts is reduced, and workability is further improved.

  FIG. 4 is a perspective view of a guide rail fueling device 7 according to a third embodiment of the present invention, and illustration of the fueling unit 4 is omitted.

  In this embodiment, a string-like or wire-like handle 10 is attached to an intermediate portion of a magnet 9 having a substantially concave planar shape along three locations A, B, and C, and a part of the handle 10 such as an end portion is attached. Is held at a location where the lubricating oil 2 does not contact, for example, the head of the display column 13 or the upper inner wall surface of the lubricating oil tank 5. The end of the handle 10 may be temporarily fixed to the head of the display column 13 or the upper inner wall surface of the lubricating oil tank 5 with, for example, an adhesive tape.

  When the magnet 9 is taken out from the inside of the lubricating oil tank 5, if the magnet 9 is pulled up by holding the end portion of the handle 10, the magnet 9 can be pulled up without soiling the hand with the lubricating oil 2. Therefore, hand washing after work can be simplified and workability is improved.

  In these embodiments, as shown in FIGS. 2 to 3, the magnet 9 is installed in the lubricating oil tank 5 so as to surround a plurality of support bases 14 to which the oil supply unit 4 is attached.

  FIG. 5 is a partial cross-sectional view for explaining a problem when the magnet 9 is laid on the bottom of the lubricating oil tank 5.

  As shown in FIG. 5, when the magnet 9 is laid on the bottom of the lubricating oil tank 5, the bottom surface of the magnet 9 comes into surface contact with the bottom surface of the lubricating oil tank 5, so that almost no gap is formed between them. The area for adsorbing the iron powder 8 decreases, and the total amount of the adsorbed iron powder 8 decreases.

  Further, as shown in FIG. 5, the guide rail oil supply device 7 is generally installed on the bracket 11. Therefore, the magnet 9 and the steel bracket 11 are close to each other, and the magnetic lines of force that come out of the magnet 9 pass through the inside of the steel bracket 11. As a result, the effective magnetic lines that attract the iron powder 8 are reduced and the magnetic force is reduced. There is also a problem.

FIG. 6 is a partial cross-sectional view of a guide rail oiling device 7 according to a fourth embodiment of the present invention.
In this embodiment, as shown in FIG. 6, a plurality of pedestals 12 made of a non-magnetic material (for example, a synthetic resin or a sintered body) are provided on the inner bottom portion of the lubricating oil tank 5, and magnets are provided on the pedestals 12. 9 is placed.

  By intervening this pedestal 12, the distance between the bracket 11 that supports the guide rail oil supply device 7 and the magnet 9 is larger than that shown in FIG. The adsorption power to 8 increases.

  Further, due to the pedestal 12, a gap 15 is formed between the bottom of the lubricating oil tank 5 and the magnet 9, and the area for adsorbing the iron powder 8 of the magnet 9 is larger than that shown in FIG. Since the total amount of the powder 8 increases, the iron powder 8 can be efficiently removed. In the present embodiment, a gap 15 is formed that is approximately the same as the thickness of the magnet 9.

  In order to suppress the reduction in the adsorption area of the magnet 9 due to contact with the pedestal 12 as much as possible, in the present embodiment, for example, a pedestal 12 having a triangular or circular cross-sectional shape is used to make a line contact with the magnet 9. ing.

  As a means for disposing the magnet 9 slightly above the inner bottom surface of the lubricating oil tank 5, there is a means for suspending the magnet 9, but the means for supporting the magnet 9 with a non-magnetic material as in the embodiment shown in FIG. The structure can be simplified and the work can be simplified.

  Although not shown in the drawings, as a fifth embodiment, a sheet magnet made of a kneaded product of a resin material and a minute magnetic material (magnetic powder), formed into a sheet shape, and magnetized only on the upper surface of the sheet is used. . When the lower surface opposite to the upper surface of the sheet-like magnet is disposed on the bottom side of the lubricating oil tank 5, the magnetic field lines can be concentrated mainly only on the upper surface of the sheet-like magnet, and the adsorption efficiency of the iron powder 8 is improved. Can do.

  When this sheet magnet is used, the shape of the magnet can be easily processed. For example, as shown in FIG. 3, a substantially concave magnet 9 that matches the shape of the lubricating oil tank 5 can be easily and inexpensively made. Can do.
