Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a current collector for a movable partition wall whose running wheels are electrically driven to rotate.

[Conventional technology] Conventionally, a movable partition wall whose running wheels are rotationally driven by electric power is provided with runners projecting upwardly attached to upper rails on both sides of the upper end of the panel so as to be freely movable.
Of the runners protruding from both sides of the upper end of the panel, only one runner was provided with a trolley having a current collector for contacting the conductor of the trolley duct arranged along the upper rail to collect current. Then, the current was collected by a collector and fed to a motor, which rotated the running wheels and caused the panel to travel.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, when the upper rail branches, the conductor of the trolley duct is cut at the branched part, so that only one runner can be connected to one panel. Since a trolley with a current collector is installed, if the current collector is located at the cut point of the conductor at the branching part, current cannot be collected.As a result, it is not possible to run the panel electrically with the branched rail. The present invention was devised in view of the above-mentioned problems of the conventional example, and its purpose is to prevent the upper wire from branching and the current collector from cutting at the branching portion, so that one Even if the trolley connected to one of the two runners installed on the panel is located in this cut section, the trolley connected to the other runner can collect current by contacting a conductor other than the cut section, and the panel's electric power To provide a current collector for a movable partition wall that causes no hindrance in running.

[Means for Solving the Problems] In the movable partition wall current collector of the present invention, runners 3 protruding upward are attached to both ends of a panel 1 so as to be freely movable on an upper rail 13, and the running wheels 2 of the runners 3 A trolley duct 15 is arranged along the upper rail 13, and the runners 3 at both ends of the panel 1 have current collectors 22 in contact with the conductor A of the trolley duct 15 to collect current. It is characterized by being provided with a trolley 18, and by adopting such a configuration, the problems of the above-mentioned conventional example can be solved and the object of the present invention can be achieved. Therefore, the trolley 18 is connected to the conductor A of the trolley duct 15.
By bringing the current collector 22 into contact with the conductor A, current is collected from the conductor A, and power is supplied to the motor 4 etc. that drive the running wheels 2 of the runner 3, thereby causing the panel 1 to run. In the part where the upper rail 13 branches, the conductor A is cut at the branch part, but even if one runner 3 is located at the cut part of the conductor A at this branch part, the remaining runner 3 is not a conductor. By contacting A, current is collected, so that there is no hindrance to the electrically driven movement of the panel 1.

[Examples] The present invention will be described in detail below based on examples shown in the accompanying drawings.

As shown in FIG. 1, runners 3 are protruded from both ends of the upper part of the panel 1, respectively. This runner 3 has three running wheels 2 on each side as shown in FIGS. 2 to 5.
is the provision. At the top of runner 3 are motor 4 and motor 4.
An electromagnetic clutch 5 is installed in the transmission path for transmitting the rotation of the vehicle to the running wheels 2. That is, an electromagnetic clutch 5 is interposed between the output shaft 6 of the motor 4 and the driven shaft 7, and the rotational drive of the output shaft 6, which is rotationally driven by the motor 4, is switched on and off to the driven shaft 7 side. ing. The rotation of the driven shaft 7 is controlled by a group of gears such as a spiral gear 8 and a spur gear 9.
Three sets of running wheels 2), each consisting of a pair of left and right wheels attached to the left and right sides of the wheel, are simultaneously driven to rotate. As shown in FIGS. 2, 3, and 11, a shaft 11 projects from the upper part of the runner 3, and a horizontally rotatable branch control wheel 12 is rotatably attached to the shaft 11. An upper rail 13 is provided on the ceiling, and the running wheels 2 of the runners 3 are mounted on the running surface 14 of the upper rail 13 so as to run freely, and the panel 1 is suspended from the upper rail 13. A trolley duct 15 is disposed above the upper rail 13 along the upper rail 13, and a power conductor 16, which is a conductor A, and a signal conductor 17 are provided in the trolley duct 15. A trolley 18 is placed in the duct 15, and wheels 19 of the trolley 18 are rotatable on a running surface 20 of the trolley duct 15. Trolley 1
8 and the runner 3 are connected by a connecting member 21,
Further, a current collector 22 is provided on the upper surface of the trolley 18, and is in contact with the power supply conductor 16 and the signal conductor 17, respectively. Reference numeral 23 in FIG. 4 indicates wiring such as a power line and a signal line led out from the trolley 18, and is connected to the motor 4 and other electrical equipment.

By the way, in the present invention, since three pairs of left and right running wheels 2 are simultaneously driven to rotate by the motor 4, for example, as shown in FIG. 6(b), the upper rail 13 is branched. In this case, which one of the three running wheels 2 on one side is always on the running surface 14 of the upper rail 13 of the branch part, and which one of the running wheels 2 rotationally driven by the motor 4 is on the running surface 14? Runner 3 is now able to run without any problems.

By the way, the upper rail 13 is provided with a branching guide 24, and the branching control wheel 12 provided on the runner 3 is guided by this branching guide 24 to determine in which direction the runner 3 moves at the branching portion of the upper rail 13. is determined.

For this reason, the direction in which each runner 3 of the panel 1 runs at the branching portion of the upper rail 13 is determined in advance, and the position and height of the branching control wheel 12 are changed accordingly.

The mutual relationship between the branch guide 24 and the branch control wheel 12 will be explained based on FIGS. 9 to 12.

FIG. 9 shows an embodiment in which a storage rail 13a for storing the panel 1 is branched at the end of the upper rail 13, and the storage rail 13a is used as the storage rail 13a1. Storage rail 1

When the branch control wheel 12a reaches the branch point between the upper rail 13 and the dummy rail 13b, it is guided by the branch guide 24a and travels to the storage rail 13aflfl. When reaching the branching part between the upper rail 13 and the storage rail 13a, the branching guide 24. The vehicle will be guided by the vehicle and will travel toward the storage rail 1Baz side. Similarly, as shown in FIG. 10(d), the runner 3 running from the upper rail 13 to the storage rail 13a has a branch guide 24a, a branch guide 24. Branch control wheel 12a, branch control wheel 12. A branch control wheel 12a is provided with a branch guide 24 when it reaches the branch part between the upper rail 13 and the dummy rail 13b.
When the branch control wheel 12° reaches the branch point between the upper rail 13 and the storage rail 13a, the branching control wheel 12° moves toward the storage rail 13a side while being guided by the branch guide 24.a. The vehicle is guided by the storage rail 13a and runs toward the storage rail 13a. Note that the branch guide 24 is provided with tapered portions 25 at both ends to guide the travel of the corresponding branch control wheel 12. When making multiple branches as described above, change the left and right positions, heights, etc. of the one-branch guide 24 placed at each branch part, and also change the direction of each runner 3 of the panel 1 at the branch part of the upper rail 13. By determining in advance whether or not the vehicle will run, and changing the position and height of the branch control wheel 12 accordingly, even if the number of branch locations increases, the branch can be reliably directed to the required location.

By the way, the trolley duct 15 also branches at the part where the upper rail 13 branches, and the power supply conductor 16 and the signal conductor 17 at this branch part are connected in the trolley duct 15 as shown in FIG. The branched power supply conductor 16 and signal conductor 17 are connected to the original power supply conductor 16 and signal conductor 17 by separate feed wiring or the like. At this cut point, the trolley 18 running in the trolley duct 15 cannot collect current because the current collector 22 does not come into contact with the power supply conductor 16 or the signal conductor 17. To solve this problem, as shown in FIG. By providing trolleys 18 on the runners 3 provided at both ends of the panel 1,
Even if one trolley 18 out of the two trolleys 18 for each panel 1 is located at the cut part of the branching part of the power supply conductor 16 and signal conductor 17, the current collector 22 of the remaining one trolley 18 is not connected to the power supply. conductor 16, signal conductor 1
7 so that current can be collected by contacting them, and there is no problem with current collection even at the branched portions.

Therefore, in the present invention, when the switch is turned on and power is supplied to the motor 4 to rotate the motor 4, the rotational drive of the motor 4 is transmitted to the runner 3 via the electromagnetic clutch 5, and the running wheels of the runner 3 are driven. It is driven to rotate and travel on the panel 1. In this case, the current collector 22 of the trolley 18 traveling in the trolley duct 15 contacts the power supply conductor 16 and the signal conductor 17 to collect current.
In the branch part, even if one runner 3 is located at the cut part of conductor A, current is collected because the remaining runner 3 is in contact with conductor A, and panel 1 runs without any problem due to electric power. It is something.

In addition, by providing a guide B having an inclined surface as shown in FIG. 8 at the end of the conductor A at the cut part at the branch part of the conductor A, the current collector 22 of the trolley 18 moves from the cut part and the conductor A This is to provide guidance when contacting. By providing the guide B in this manner, even if there is a step difference between the conductors A on both sides, the current collector 22 can be smoothly guided and brought into contact with the conductor A.

In addition, in the case of a power outage, the electromagnetic clutch 5 is disconnected and the running wheels 2
is free, so even if the panel 1 is moved manually, the running wheels 2 of the runner 3 can be rolled, and therefore the panel 1 can be moved manually. On the other hand, if the motor 4, electromagnetic clutch 5, etc. break down, the exterior material of the panel 1 can be replaced because the motor 4, electromagnetic clutch 5, etc. are not installed inside the panel 1, but are mounted on the runner 3. It is designed so that it can be repaired or replaced in the same way as repairing or replacing the runner 3 without removing it, and maintenance and inspection can also be easily performed.

[Effects of the Invention] As described above, in the present invention, runners projecting upward are attached to the upper rail at both ends of the panel so as to be freely movable, and the running wheels of the runners are electrically driven.
The trolley duct is arranged along the upper rail, and the runners at both ends of the panel are each provided with a trolley having a current collector in contact with the conductor of the trolley duct, so the upper rail branches. Even if the conductor is cut at the branched part, even if one runner is located at the cut part of the conductor at this branched part, the remaining runner will still be in contact with the conductor and will collect current. This has the effect that there is no problem with the panel's electric drive.
