Description

  The present invention relates to a shutter guide rail protection device, and more particularly to a device for protecting a guide rail of a shutter provided in the vicinity of a cargo elevator entrance at a cargo collection place or the like.

  As shown in FIGS. 1 and 5, a cargo warehouse 1, such as a distribution warehouse, a department store, and a supermarket that handles a wide variety of cargo, is provided with an elevator 2 dedicated to cargo. In order to ensure safe operation of the elevator 2, a shutter 3 is provided near the entrance / exit 5 of the elevator 2. The guide rail 4 of the shutter 3 is partially embedded in the wall surface in the vicinity of the elevator doorway 5.

  For complicated and busy operations such as freight accumulation, organization, packing, and shipping, workers are obstructions such as freight, freight carriages, cleaning tools (for example, bags, mops, etc.), collection / delivery / packing tools, etc. (FIG. 5) may be temporarily temporarily placed in the vicinity of the entrance / exit 5 of the elevator 2 easily. These obstacles X are inadvertently left unattended and sometimes fall over. Since the elevator entrance / exit 5 may be provided with a gentle slope for climbing or descending, the obstacle X often falls, moves, etc., and when the cargo cart is taken in and out of the elevator 2 or the shutter 3 is opened / closed. In the meantime, disturb your work.

  In order to prevent such an accident in advance, as shown in FIG. 5, a pressure sensor 6 is attached to the lowermost end of the shutter 3, and when the pressure sensor 6 comes into contact with the obstacle X, the lowering of the shutter 3 is stopped safely. Some are provided with a device. However, a gap G is usually provided between the longitudinal ends of the pressure sensor 6 and the end face of the guide rail 4 in order to make the shutter 3 move smoothly. In particular, in the gap G, as shown in the figure, for example, the shutter 3 may be closed in a state where the rectangular plate X1 is inadvertently leaned. In such a case, the pressure sensor 6 cannot detect the plate X1. Therefore, the function of the safety device is not exhibited.

  The problem with the present invention is that it is difficult to place obstacles against the guide rails of the shutters that are provided near the cargo elevator entrances at cargo freight collection facilities, etc., and even if obstacles are placed, they can easily move to the vicinity of the guide rails. An object of the present invention is to provide a shutter guide rail protection device that does not.

  A shutter guide rail protection device based on the present invention is a device for protecting a shutter guide rail provided at a cargo elevator entrance at a cargo collection place, etc., and guides an L-shaped angle material on a wall surface near the cargo elevator entrance. It has a structure in which it is fixed by fasteners at both sides in the width direction of the rail and at opposite positions of the guide rail.

  It is preferable to provide a marker for alerting a person on the outer surface of the L-shaped angle member. The marker may be a colored sticker or fluorescent colored sticker attached to the outer surface of the L-shaped angle member, or a colorant or fluorescent colorant applied to the outer surface of the L-shaped angle member. The fastener may include an anchor bolt and a nut.

  According to the shutter guide rail protection device of the present invention, since the L-shaped angle members are provided on both sides of the guide rail, the obstacle does not interfere with the guide rail and makes it difficult to place the obstacle near the guide rail. . Furthermore, the obstacle does not move carelessly to the vicinity of the guide rail. The marker provided on the outer surface of the L-shaped angle member can be visually recognized even in a dark place, and also serves as a warning sign for the operator. Therefore, the safe opening and closing of the shutter and the safe operation of the cargo dedicated elevator are ensured, and the transport cart can be taken in and out of the elevator safely and quickly.

  Next, with reference to FIGS. 1-4, the Example of the shutter guide rail protection apparatus based on this invention is described. As shown in FIG. 1, a shutter guide rail protection device 10 according to the present invention protects a guide rail 4 of a shutter 3 provided in the vicinity of a cargo dedicated elevator entrance / exit 5 in a cargo collection / delivery place 1 or the like. As shown in FIGS. 1 and 4, the protective device 10 is configured so that the L-shaped angle member 11 is placed on both sides of the guide rail 4 in the width direction (see FIG. 4) and the opposite position of the guide rail 4 (see FIG. 4). The structure is fixed to the fastener 12 (see FIG. 1).

  As shown in FIGS. 2 and 3, the L-shaped angle member 11 includes an inner projecting portion 11a and a fixing portion 11b to the wall surface. The fixing portion 11b has bolt holes 111 at predetermined intervals along the longitudinal direction. Is provided.

  As shown in FIG. 4, it is preferable to provide a marker 13 on the outer surface of the inner projecting portion 11 a and the fixed portion 11 b of the L-shaped angle member 11. The marker 13 is applied to the outer surface of the inner protruding portion 11a and the fixing portion 11b of the L-shaped angle member 11 or the colored sticker or fluorescent coloring sticker attached to the outer surface of the inner protruding portion 11a and the fixing portion 11b of the L-shaped angle member 11. A colorant or a fluorescent colorant may be used. The marker 13 provided on the outer surface of the inner projecting portion 11a and the fixed portion 11b of the L-shaped angle member 11 can be visually recognized even in a dark place, and also serves as a warning sign for the operator. It should be noted that the length, width, and thickness in the longitudinal direction of the inner protruding portion 11a and the fixed portion 11b of the L-shaped angle member 11 can be appropriately changed. Furthermore, in order to prevent human injury, the cushion material A may be provided along the longitudinal direction at the front of the inner projecting portion 11a of the L-shaped angle member 11, or the upper end of the front surface portion may be rounded.

  As shown in FIG. 4, the fastener 12 may include an anchor bolt 121 embedded in a wall surface in the vicinity of the cargo elevator entrance 5 and a nut 122 that is detachably screwed thereto.

  The shutter guide rail protection device of the present invention is not only provided in the vicinity of the freight elevator entrance / exit of the freight collection place, but can also be easily applied to the vicinity of the general elevator entrance / exit and the general shutter entrance / exit.

It is a top view of a part of cargo distribution place equipped with the shutter guide rail protection device of the present invention. It is the side view of the angle material which comprises the shutter guide rail protection apparatus seen from the II-II line | wire of FIG. FIG. 3 is a right end view of the angle member of FIG. 2. FIG. 4 is a perspective view of a part of the shutter guide rail protection device as seen from line IV-IV in FIG. 1. It is a front view of the conventional shutter.
