Abstract

PURPOSE:To exactly transmit signals of fillet extension to each panel by eliminating the needs for placing signal lines to transmit the signals of fillet extension to each panel on a guide rail. CONSTITUTION:When the signals of fillet extension are sent out from a signal outgoing device 37 provided in the final panel 7, a driver 16 for the final panel 7 is actuated to extend fillets 12. An optical beam is projected toward the preceding panel 6 from a projector 38, and afterwards fillet extension signals are transmitted in a chain reaction manner through the projector 38 and a receiver 39 to the foremost panel 5 from preceding each panel 6. The driver 16 for the panels 6 and 5 is actuated to extend all fillets 12.

Note that the basic structure is almost the same as the conventional one shown in FIGS. 3 to 5, and the same reference numerals are used to indicate the same components, and detailed explanations thereof will be omitted.

As shown in FIG. 1, all panels (5) (6)
(7) are provided with driving means (16) for extending and retracting the fillet (12) (the intermediate panel (6) is not shown)

Each drive means (16) includes a motor (17), a screw rod (18) which is rotated by the motor (17) and has screws in both left and right directions, and a pair of left and right screw rods that are screwed into the screw rod (18). nut (19) and the base end is both nuts (19)
Four links (20) forming a nearly diamond-shaped pantograph are pivoted to the top, two upper links (20), and two lower links (20), one end of which is pivoted to each tip. It is composed of two lifting rods (21) facing in the vertical direction, and these two lifting rods (21) are fixed to the lower and upper surfaces of the upper and lower fillets, respectively.

When the motor (17) is rotated in a predetermined direction (hereinafter referred to as normal rotation), the screw rod (18) is rotated, and the screw rod (18) and each nut (19) are screwed together at that time. By moving both nuts (19) inwardly, the four links (20) extend vertically, thereby causing the upper fillet (12) connected to each lifting rod (21) to The upper and lower fillets (12) extend downward, respectively.

When the motor (17) is rotated in the opposite direction to that described above (hereinafter referred to as reverse rotation), the operation opposite to that described above results in the following:

It is detected that each fillet (12) has been retracted to a predetermined storage position, the motor (17) stops reversing, and the actuator (22) comes into contact with the lower limit switch (24). When it is detected that the fillet (12) has extended by a predetermined amount, the normal rotation of the motor (17) is stopped. These motors (17) are controlled by control devices (25) provided at each of (5), (6), and (7).

The final panel (7) has a fillet (1

34) is a guide rod that guides the lateral movement of the sub panel (11).

When the sub-panel (11) moves leftward to the position shown by the solid line in FIG. 2
7) is a limit switch that stops the rotation of the sub panel (11) in the retracting direction.

(37), as shown by the imaginary line in FIG.
) is a limit switch that comes into contact with the actuating piece (36) and is activated to stop the rotation of the motor (27) in the direction in which the sub panel (11) extends. The limit switch (37) serves as a signal generator that generates a fillet extension signal.

[0027] That is, this limit switch (37)
is activated, the signal is sent to the control device (25) of the final panel (7) as both a stop command signal and a fillet extension signal for the motor (27),

Furthermore, the signal transmission circuit (25a) provided in the control device (25) directs the light beam from the projector (38) provided on the left end surface of the last panel (7) to the preceding panel (
6).

In addition to the above-mentioned control device (25), each intermediate panel (6) is provided with a light receiver (39) on the right end surface, a light projector (38) on the left end surface, and a light receiver (39) on the left end surface. 3

Next, the operation of the above-mentioned device will be explained. Figure 1 shows that the first panel (5), the middle panel (6), and the last panel (7) have finished self-propelling, and the sub-panel (11) of the last panel (7) has extended. It shows the state immediately before.

When the self-propelling of the final panel (7) is completed and the final panel (7) comes into contact with the intermediate panel (6) preceding the final panel (7), the final panel (7) The provided limit switch (10) (see FIG. 5) operates to send a signal to the motor (27), causing the motor (27) to operate.

By the operation of this motor (27), the advance/retreat device (26) described above is operated, and the sub-panel (11) is extended to close the gap between the final panel (7) and the wall (3). . At this time, the actuating piece (36) provided on the lower drive pipe (31) activates the limit switch (37), which is a signal generator, almost at the same time as the sub panel (11) completes closing the gap.
The signal at the time of this contact is sent to the control device (25), the drive means (16) is activated, and the fillet (1
2) is extended to close the gap between the ceiling (1), the floor (2) and the final panel (7).

Furthermore, if necessary, when transmitting the fillet extension signal from each panel to the next panel, an appropriate delay time is provided so that the drive means of each panel operate almost simultaneously and the power supply line is connected at once. It may also be possible to prevent a large current from flowing at times.

At the same time that the fillet extension signal is applied to the control device (25), the signal transmission circuit (25a) is activated, and the intermediate panel (

In the first panel (5), when the light receiver (39) receives the light beam projected from the subsequent panel (6), the driving means (16) is activated by the control device (25). When activated, the fillet (12) is simply extended, no further fillet extension signal is transmitted, and the partitioning is completed.

In this way, each panel (5), (6), and (7) is equipped with a control device (25), a light receiver (39), and a light emitter (38).
By providing these, it is no longer necessary to provide a signal line for extending the fillet.
