て可動体１０が案内溝２を広げる方向へ変位する。The operation of the elevator sliding door device constructed as described above will be explained with reference to the flowchart shown in FIG. That is, when an opening/closing command is issued in step 101, the driving machine 6 is energized by the control device 12, and the sliding door 3 is opened/closed. Then, the process advances to step 102, and if the sliding door 3 has not reached the end of the opening/closing stroke, that is, if the fully open detector 8 or the fully closed detector 9 does not operate, the process advances to step 103. In step 103, if the predetermined time has elapsed, the process returns to step 102, and if the predetermined time has elapsed, the process proceeds to step 104, assuming that the sliding door 3 is in the middle of the opening/closing process and its operation is obstructed. In step 104, the control device 1
2 causes the drive unit 6 to move backward, and the sliding door 3 moves back to the position before the opening/closing operation. Next, in step 105, a widening command is issued from the control device 12, the actuator 11 is energized, and the movable body 10 is displaced in the direction of widening the guide groove 2.

7, the control device 12 issues a command to remove the foreign matter in the guide groove 2, the drive unit 6 is energized, and the sliding door 3 is opened and closed again at a low speed. This allows the foreign matter to be removed from the guide piece 3a.
When the sliding door 3 reaches the end of the opening/closing stroke by being pushed by the sliding door 3 and is ejected from the end of the guide groove 2, and the fully open detector 8 or the fully closed detector 9 is activated, the process proceeds from step 108 to step 110. Further, in step 108, if the foreign object cannot be removed even if the sliding door 3 operates to remove foreign objects, and the sliding door 3 is obstructed in the middle of the opening/opening operation, the process proceeds to step 109 and step 11.
Go to 1. If N is not 3 in step 111, the process returns to step 107 via step 112. Further, if N is 3 in step 111, that is, if the foreign object cannot be removed even after repeating the foreign object removal operation three times and the sliding door 3 has not reached the end of the opening/opening stroke, the process proceeds to step 113 and the control device 12 detects an abnormality. The alarm 13 is energized to notify of the abnormality, and the process proceeds to step 114, where the elevator operation is stopped.

ができる。When the foreign object is removed, a recovery command is issued from the control device 12 in step 109, and the driving machine 6 returns to normal operation, and the actuating machine 11 is energized to return the movable body 10 to its previous position. The return guide groove 2 has a normal width. In this way, it is possible to prevent foreign objects from getting stuck in the guide groove 2, and to easily remove the foreign objects by the operation of the sliding door 3, thereby reducing elevator operation problems caused by foreign objects. Further, when foreign matter cannot be discharged, an abnormality is notified, so that restoration and maintenance can be quickly taken care of.

する効果がある。[Effects of the Invention] As explained above, the present invention includes a movable body and an actuator that widen the guide groove into which the lower edge of the sliding door is fitted, and prevents the opening/closing operation of the sliding door from being obstructed by foreign matter in the guide groove. In some cases, the guide groove is widened to facilitate the removal of foreign matter. This has the effect of reducing elevator accidents caused by foreign matter getting stuck in the guide groove and making the sliding door inoperable.
