Embodiment 5. FIG.
FIG. 14 conceptually illustrates the main part of the movable fence device according to Embodiment 5 of the present invention, and FIG. 14 (a) is a perspective view showing the state of the transmission mechanism when the three movable fences are fully closed. 14 (b) is a perspective view showing a state when three movable fences are assembled at the other end (right end), and FIG. 14 (c) is a diagram when three movable fences are gathered at the central part. It is a perspective view which shows a state. In the fifth embodiment, predetermined two of the three movable fences 5 are simultaneously driven by one drive motor so as to be gathered at the central portion or the right end portion of the moving path 4. In the drawing, a traction member 55a fixed to the first movable fence 5a (not shown) is arranged on the left end side of the drawing, and a traction member 55c fixed to the third movable fence 5c is arranged on the right end side of the drawing. It has two belt reversing wheels 991 and 992 that are rotatably provided to the second movable fence 5b (not shown) in the center, and are attached to the second movable fence 5b. A pulling member 55b is provided.

  The drive motor 8 having the driving roller 9R and the tension wheels 941 and 942 are disposed on the left end side further than the left pulling member 55a, and three more on the right end side than the right pulling member 55c. Tension wheels 951, 952, and 96 are all rotatably disposed. Then, one end portion of the first timing belt 981 serving as a transmission means is fixed to the left pulling member 55a, and in the other end portion direction, the drive roller 9R, the tension wheel 951, the tension wheel 952, and the belt reversing wheel 991. After being wound sequentially, it is fixed to the right pulling member 55c. Further, one end of the second timing belt 982 serving as a transmission means is fixed to the left pulling member 55a, and the belt reversing wheel 992, the tension wheel 941, the tension wheel 942, and the tension wheel 96 are arranged in the other end direction. After being wound sequentially, it is fixed to the right pulling member 55c. Other configurations are the same as those of the first embodiment shown in FIG.

  The operation of the fifth embodiment configured as described above will be described. To move the three movable fences 5 (not shown) from the fully closed state shown in FIG. 14 (a) to the right end part side of the figure and open the left end part and the central part, the third movable fence 5 That is, the pulling member 55c is locked by a lock mechanism (not shown), and the drive motor 8 is rotated in the clockwise direction indicated by the arrow in FIG. Since the right pulling member 55c is locked, the first timing belt 981 pulls the pulling member 55b, that is, the second movable fence to the right via the central belt reversing wheel 991.

  When the pulling member 55b is pulled in the right direction, a tensile force acts on the second timing belt 982 via the belt reversing wheel 992, and the other end of the second timing belt 982 is pulled to the right. By being fixed to the member 55c and being locked, the portions wound around the tension wheels 941 and 942 are in a fixed state, and eventually the same speed as the speed at which the first timing belt 981 is fed in the arrow direction by the drive roller 9R. Then, the left pulling member 55a is pulled rightward, and the first movable fence 5a is moved rightward as indicated by an arrow F. Since the pulling member 55b fixed to the second movable fence 5b in the center is pulled by the timing belt 981 with 2: 1 roping, the second movable fence 55b is half the speed of the first movable fence. It is obvious that the fence moves. Moreover, what is necessary is just to rotate the drive motor 8 counterclockwise, when closing the open movable fence.

  On the other hand, when the three movable fences are gathered in the central part from the closed state of the three movable fences shown in FIG. 14A, the traction member 55b coupled to the second movable fence in the central part is not shown. The drive motor 8 is rotated in the clockwise direction. When a tensile force in the direction of arrow G shown in FIG. 14C acts on the first timing belt 981, the traction member 55b is locked and does not move, and the belt reversing wheel 991 is rotatable. Therefore, the pulling member 55c is moved in the direction of the arrow H, and the third movable fence (not shown) is moved to the center.

  Since the other end portion of the second timing belt 982 is fixed to the pulling member 55c, the second timing belt 982 is moved in accordance with the movement of the pulling member 55c in the arrow H direction (left direction in the figure). The first pulling member 55a, which is pulled in the right direction indicated by the arrow I through the tensioning wheel 96 and the tensile force is coupled to one end side via the tensioning wheels 942, 941 and the belt reversing wheel 992, is indicated by the arrow J. As shown, the first movable fence 5 a (not shown) is gathered at the center of the moving path 4.

  Needless to say, when closing, the drive motor 8 is rotated counterclockwise. In the configuration shown in the figure, the three movable fences cannot be assembled at the left end, but the drive motor 8 is one and the three movable fences can be assembled at the center and the right end (or the left end). Therefore, it can provide at low cost by using in combination with the said Embodiment 1 and the existing movable fence apparatus according to a use. Further, the second and third movable fences require a locking mechanism, but it is not wasteful because it is useful to fix the fences even while the movable fence is closed.

  In the description of the above embodiment, the transmission mechanism 98 is a transmission means 98 such as a timing belt and a tension wheel or a roller that meshes with the transmission means 98. However, the present invention is not limited to this. For example, the same effect can be obtained by using other transmission means such as a chain, a rope, and a gear. Moreover, although the drive unit 6 which accommodates the drive device 7 etc. was provided in the lower part of the platform 2, it can also be provided in the upper part. In addition, it goes without saying that various modifications and changes can be made within the spirit of the present invention.
