Description

  The present invention relates to a structure of a foldable automatic gate used for an exterior and an opening / closing control device.

  As an electric gate of an automobile garage, a gate that opens and closes by rotating a gate with an arm attached to the gate with a motor mounted on a column (see, for example, Patent Document 1), a gate between frames An expandable gate (see, for example, Patent Document 2) has been proposed in which elements are connected in a pantograph manner and the gate is opened and closed by expanding and contracting the whole. On the other hand, in recent years, there has been a demand for a vehicle having a high opening height and a wide frontage, corresponding to a high roof vehicle having a high vehicle height and a plurality of vehicles. However, with the conventional flip-up gate, it is difficult to make the opening height high enough for a high-roof car to pass through. The telescopic type has a folding thickness when the gate is opened (when the element is folded). Therefore, there is a problem that the effective opening of the opening cannot be widened. Furthermore, these gates open and close the fence-like gates and do not have doors, so there is a security problem.

  There is a foldable gate that allows a wide opening height and a wide effective opening, and is equipped with a door to meet security requirements, but the foldable gate has a complicated opening and closing operation, Since the weight is large, it is difficult to automate, and manual opening and closing is common. On the other hand, as for a relatively small and light indoor folding door, an automatic opening / closing door having a folding structure that rotates and slides the door via a planetary gear mechanism has been proposed (for example, see Patent Document 3). ).

JP-A-6-240965 JP-A-11-107622 JP 2001-214662 A

  As shown in FIG. 12 (a), this automatic opening / closing door has a drive rotary shaft door 101c and a slide rotary door 101a connected to each other by an intermediate hinge 101b, and the doors are connected to each other by a rotary shaft 116a. Yes. The load of the slide rotary door 101a is supported by the drive rotary shaft door 101c via the intermediate hinge 101b, and the load of the whole connecting door is supported by the drive rotary shaft 116 in a cantilever manner. For this reason, the upper running rail 123 and the lower guide portion 128 are not subjected to the weight of the slide rotary door 101a, and have a structure with little slide resistance. However, such a structure that supports the articulated door in a cantilevered manner is a lightweight indoor door and can be applied to a case where there are two articulated doors. There are the following problems to apply to many exterior gates.

  FIG. 12B shows a case where the same opening / closing structure is applied to an exterior gate having a plurality of sliding rotary doors 101a and the load is applied to the traveling rail 123 or the lower guide portion 128. In this case, a hinge 151 having a rotating portion 152 is attached to each door between the end surfaces of the doors so as to be rotatable with respect to each other. Since the weight of the slide rotary door 101a is supported by the lower rotary shaft 154 attached to one end of the door, the lower rotary shaft 154 supports the weight of the slide rotary door 101a while rotating the door and the direction of the lower guide portion 128. It is necessary to cope with movement in two directions, that is, movement along the direction. Further, since each of the rotary shafts 153 and 154 of the slide rotary door 101a is attached to one end of the door, when the door is opened (folded), the center of gravity of the slide rotary door 101a is the traveling rail 123 and the lower part. It pops out in the lateral direction of the guide part 128. For this reason, lateral loads F1 and F2 are applied to the traveling rail 123 and the lower guide portion 128 to counter the moment generated by the weight of the door (see FIG. 12C). As a result, in addition to the weight of the slide rotary door 101a, the lower rotary shaft 154 needs to rotate and move while receiving a lateral force. Similarly, the upper rotating shaft 153 needs to rotate and move while receiving a lateral force. For this reason, the sliding wheel 124, the wheel 127 connected to each of the rotating shafts 153 and 154, the traveling rail 123 on which the wheel travels, and the lower guide portion 128 are rubbed due to the above-described lateral force. Will be caused. This tendency becomes more prominent as the weight of the slide revolving door 101a increases. Therefore, when the automatic opening / closing device of the prior art is applied to an exterior gate as shown in FIG. It will be necessary to make it lighter. However, since the opening height necessary for the garage is determined, it is necessary to reduce the width of each door in order to reduce the weight of each door. As a result, the number of doors constituting the frontage increases, the folding thickness in the folded state increases, and the effective opening frontage size in the open state decreases. Further, since the exterior gate has a large number of sliding revolving doors and there is a backlash between the doors, there is a problem that smooth opening and closing becomes difficult by constant rotation and sliding movement as in the prior art.

  Accordingly, an object of the present invention is to provide a high opening height, a wide effective opening size, and a smooth opening / closing operation in an exterior gate with a heavy door and a large number of connected doors. It is to provide a simple folding automatic opening and closing gate.

  INDUSTRIAL APPLICABILITY The present invention has an excellent effect that it can take a high opening height and a wide effective opening size and can perform a smooth opening and closing operation in an exterior gate with a heavy door and many connected doors. .

  Hereinafter, the folding automatic gate and the opening / closing control device of the present invention will be described with reference to the drawings.

  FIG. 1 shows a foldable automatic gate according to an embodiment of the present invention, wherein (a) shows a front view and (b) shows a plan view. The foldable automatic gate of this embodiment has a door-holding column 1 and a folding column 3 on the left and right, and an upper structure 11 is disposed between these columns. As shown in FIG. 1B, each panel 9 constituting the gate 5 is connected to each other by a hinge 7 so as to be freely rotatable, and between the door-end side column 1 and the folding side column 3. The gate is closed by extending, and the gate is opened by folding along the folding column 3.

A traveling rail 13 is attached to the inside of the upper structure 11, and a slider 15 with traveling wheels attached travels on the traveling rail 13, and the center axis of rotation of each panel 9 extends from the slider 15. 17 is suspended in a freely rotatable manner. In addition, an electric sprocket 19 and a traveling motor 20 are disposed inside the door-end side strut side of the upper structure 11, and the chain is stretched between the rotating sprocket 21 attached to the folding side strut side. The travel drive mechanism 25 is formed by 23. The travel drive mechanism 25 is connected to the travel drive panel 31 on the door-holding column side of the gate 5 by a connecting member 27. Further, a linear motion cylinder 33 for rotationally driving the panel is mounted on the folding side column side of the upper structure 11 so as to freely swing in the horizontal direction. The linear motion cylinder 33 is rotationally driven on the folding side column side of the gate 5. The rotation arm 37 fixed to the rotation center shaft 17 of the panel 39 and the link 35 are connected.

  The suspension structure of the panel 9 and the travel drive mechanism 25 will be described in detail with reference to FIGS. In FIG. 2, (a) is a figure which shows the whole cross section of a foldable automatic gate, (b) has shown the partial expanded cross section of the thrust bearing part. The panel 9 is made of a metal such as aluminum, and the upper and lower portions are thick so that support members can be attached. A reinforcing collar 32 is fixed by welding around the upper hole in the center of the width direction of the panel 9, and the fixing screw portion of the rotation center shaft 17 is passed through the collar 32 and the lock nut 30 is tightened from the inside of the panel. The rotation center shaft 17 and the panel 9 are fixed integrally. The rotation center shaft 17 has a step portion that is seated on the thrust bearing 22 and transmits a load. On the other hand, a rotation center bearing seat 24 having two step portions inside is fixed to the slider 15 by welding, and a thrust bearing 22 is fitted on the lower step portion. A thrust bearing seating step portion of the rotation center shaft 17 abuts on the upper portion of the thrust bearing 22, and the load of the panel 9 is transmitted to the slider 15 via the rotation center shaft 17, the thrust bearing 22 and the rotation center bearing seat 24. And can be rotated smoothly. A bearing retainer 28 fixed to the rotation center shaft 17 is rotatably fitted in the upper step portion of the rotation center bearing seat 24 so that the thrust bearing 22 is held from the surroundings and can be operated stably. . A guide wheel 26 is attached to the upper portion of the rotation center shaft 17 so as to be freely rotatable. The guide wheel 26 is fitted to the rotation center shaft upper guide 18 disposed on the upper structure 11 in parallel with the traveling rail 13. This prevents the panel 9 from sagging and enables reliable rotation and running. Further, a lower steady rest 92 that fits into a lower guide rail 91 provided on the foundation and prevents the panel 9 from swinging is rotatably attached to the lower portion of the panel 9 by mounting bolts 94. With the above-described structure, the panel 9 is suspended from the slider 15 so as to be freely rotatable by the rotation center shaft 17 at the center in the width direction.

  A traveling rail 13 is fixed on the traveling rail support 14 of the upper structure 11, and traveling wheels 16 traveling on the traveling rail 13 are rotatably attached to the slider 15. Accordingly, the weight of the panel 9 is transmitted to the traveling wheel 16 and the traveling rail 13 via the slider 15 and supported by the upper structure 11. The traveling rail 13 is disposed at a position close to the rotation center shaft 17 so that a bending moment due to the weight of the panel 9 applied to the slider 15 is reduced. On the other hand, as shown in FIG. 3, two slider guide wheels 38 are attached to the flat plate portion of the slider 15 opposite to the rotation center bearing seat 24 so as to be rotatable in a horizontal plane. These fit into the slider guide 36 disposed in the upper structure 11 in parallel with the traveling rail 13, counteract the lateral force of the traveling rail 13 of the slider 15, and are applied to the traveling rail 13 of the slider 15. In addition to making it possible to travel reliably in the direction along, the slider 15 prevents the slider 15 from rotating due to a reaction force when the panel 9 rotates in cooperation with the traveling wheel 16.

  The chain 23 of the traveling drive device 25 is connected by a take-up 40 so as to form an annular shape. A travel slider 29 that suspends a travel drive panel 31 disposed on the door-contact side column side of the gate 5 in the slider 15 is connected to the take-up 40 by a connecting member 27 and is travel-driven by the travel drive mechanism 25. It has become so.

  As described above, since the panel 9 is rotatably suspended by the rotation center shaft 17 provided at the center in the width direction, the lateral force due to the weight of the panel 9 is not applied to the traveling rail by the folding operation. A panel 9 having a large weight is used for the gate 5, and the folding opening thickness can be reduced to increase the effective opening front dimension.

  Next, the rotation mechanism of the rotation drive panel 39 disposed on the folding-side column side of the gate 5 will be described with reference to FIG. 2 and 3 are denoted by the same reference numerals and description thereof is omitted. A rotation arm mounting collar 42 is fixed to the rotation center shaft 17 of the rotation drive panel 39. A rotary arm 37 is fixed to the collar 42, and the rotary arm 37 is connected to a linear motion cylinder 33 via a link 35, and the rotary drive panel 39 is rotated by the operation of the linear motion cylinder 33. On the other hand, a stopper arm 41 is fixed to the side of the collar 42 facing the rotating arm 37. The stopper arm 41 is substantially L-shaped, and has a curved surface portion 44 that abuts on the engaging portion 45 of the stopper 43 on the outer end surface of the bent portion, until a predetermined angle is reached during the opening operation. The rotation drive panel 39 can be restricted from moving along the direction of the traveling rail 13. The stopper 43 is attached to a mounting portion 47 fixed to the upper structure 11 (not shown) by a pin 49 so as to be rotatable. The stopper 43 has a convex portion 51 in contact with the upper structure 11 at the top, and a restoring spring 57 stretched between the stopper 43 and the upper structure 11 is attached to the side surface.

  Next, the rotation operation of the rotation drive panel 39 by the rotation arm 37 and the operation of the stopper 43 will be described with reference to FIGS. FIG. 5 is a diagram showing an opening operation of the rotary drive panel 39, and FIG. 6 is a diagram showing a closing operation.

When the gate 5 is closed, the linear cylinder 33 is in the shortened position, and the stopper arm 41 is in contact with the locking portion 45 of the stopper 43 at its end. The stopper 43 is stretched in the direction of the upper structure 11 by the restoring spring 57, and the state where the convex portion 51 is in contact with the upper structure 11 is maintained. In the opening operation, even if the expansion of the linear cylinder 33 is started, the rotation drive panel 39 does not start rotating because the angle of the rotary arm 37 with respect to the expansion direction of the linear cylinder is shallow. Starting to move, the stopper arm 41 is pressed against the locking portion 45 of the stopper 43. However, since the stopper 43 is in a state in which the convex portion 51 cannot rotate due to contact with the upper structure 11, the movement of the rotary drive panel 39 to the folding side column 3 is restricted by the stopper 43, and the straight line of the linear motion cylinder 33 is limited. The motion can be converted into a rotational motion. Thereafter, the rotation drive panel 39 starts to rotate around the rotation center axis 17 by the extension operation of the linear motion cylinder 33. At this time, the direct acting cylinder 33 swings its head in the horizontal direction in accordance with the movement of the link 35. When the linear motion cylinder further expands, the position of the stopper arm 41 is disengaged from the locking portion 45 of the stopper 43 by the rotation of the rotation center shaft 17. At this time, since the angle of the rotation arm 37 with respect to the extending direction of the direct acting cylinder is considerably large, the rotating drive panel 39 rotates smoothly by the extending operation of the direct acting cylinder 33. Finally, the rotary drive panel 39 is folded up to the folding position along the folding side column 3.

In the case of the closing operation, the relationship between the movement position of the rotation drive panel 39 in the direction along the traveling rail 13 and the rotation angle is different from that in the above-described opening operation, and the stopper arm 41 is located on the folding side column side of the stopper 43. It hits the curved surface part 55. However, since the stopper 43 rotates around the pin 49 as shown in FIG. 6, the movement of the stopper arm 41 in the direction of the door-end side column 1 is not limited, and the rotation drive panel 39 can continue the closing operation. Further, when the rotation drive panel 39 moves toward the door stop side column 1 and rotates toward the closed position, the stopper arm 41 moves to the door contact side column side of the locking portion 45 of the stopper 43. Then, the stopper 43 is urged by the restoring spring 57 in the direction of the upper structure 11 so that the convex portion 51 comes into contact with the upper structure and returns to the state shown in FIG. Thereafter, the rotation drive panel 39 continues to rotate and travel until it is closed. In the above closing operation, as in the opening operation, the direct acting cylinder 33 swings its head in the horizontal direction in accordance with the movement of the link 35.

  By such a stopper 43, the rotation drive panel 39 can be smoothly started to rotate during the opening operation, and the rotation and travel operation of the rotation drive panel 39 are not restricted during the closing operation, and the rotation required for the folding automatic gate is possible. There is an effect that the cooperative operation of the operation and the traveling operation can be made possible.

  Next, an embodiment of the folding automatic gate opening / closing control device 61 of the present invention will be described with reference to the drawings.

  FIG. 7 shows the configuration of the folding automatic gate opening / closing control device 61 of the present invention. Various limit switches for opening / closing control are installed on the folding automatic gate. As for the expansion / contraction position of the linear motion cylinder, a linear motion cylinder extension limit switch 73 and a linear motion cylinder contraction limit switch 75 are provided. As for the open / close position of the travel drive panel 31, an open limit switch 77 for detecting a fully open state, an open / decelerate limit switch 79 for detecting a deceleration start point during an open operation, and a close limit switch for detecting a fully closed state. 81. A closed deceleration limit switch 83 for detecting a deceleration start point in the closing operation is provided. These limit switch signals are input to the open / close control device 61. Further, an open switch 67, a close switch 69, and a stop switch 85 necessary for the operation are arranged on the operation panel, and signals thereof are input to the open / close control device 61. The opening / closing control device 61 outputs a frequency signal and an output signal for controlling the rotational speed to the inverter circuits 63 and 65 that control the rotational speed of the linear motion cylinder 33 and the traveling motor 20 according to the frequency according to the input state. The rotational speeds of the direct acting cylinder 33 and the traveling motor 20 are controlled according to the frequency of the electric power output from the respective inverter circuits 63 and 65. Further, an operation signal of the brake drive circuit 87 is output from the opening / closing control device 61, and the brake device of the traveling motor 20 is configured to operate by this operation signal.

Next, the opening operation of the gate 5 will be described with reference to FIGS.
(1) When the open switch 67 is pressed, the opening operation is started from the closed state (FIG. 8A). First, the opening / closing control device 61 outputs a frequency signal to the linear motion cylinder inverter circuit 63 to drive the linear motion cylinder 33. As a result, the driving of the linear cylinder 33 is started. The linear cylinder 33 continues to operate for a predetermined time by a timer in the opening / closing control device 61, and rotationally drives the rotary drive panel 39 to an angle of about 20 degrees. At this time, the traveling motor 20 is idling. Since each panel 9 is suspended from a slider 15 that travels on the traveling rail 13 and is connected to each other by a hinge 7, each panel 9 rotates in accordance with the rotation of the rotary drive panel 39 and is attached to the folding side column 3. Move toward the first position. (FIG. 8B, a1 to c1 in FIG. 9A, and p1 to q1 in FIG. 9B).
(2) When each panel 9 reaches the first position, a frequency signal for driving the driving panel is output from the opening / closing control device 61 to the driving motor inverter circuit 65, and the driving motor inverter circuit 65 has a predetermined frequency. Electric power is output to the traveling motor 20 and the driving of the traveling motor 20 is started. In the present embodiment, the first position is detected by the timer, but the actual panel position may be detected by a limit switch or the like (FIG. 9 (b) q1 to r1).
(3) The traveling motor 20 and the direct acting cylinder 33 are simultaneously driven to rotate the rotational drive panel 39 and fold the traveling drive panel 31 along the traveling rail 13 in the direction of the folding side column 3 (FIG. 8). (C)). At this time, the traveling speed of the traveling drive panel 31 and the rotational speed of the rotary drive panel 39 must be coordinated with each other. Therefore, the open / close control device 61 outputs separate frequency signals to the inverter circuits 63 and 65 so that the mutual speeds can be coordinated. As an example, the frequency command value for the linear motion cylinder inverter circuit is 26 Hz, and the frequency command value for the travel motor inverter circuit is 52 Hz. This ratio can be freely set in the control device depending on the rotation mechanism, the dimensions of the panel, and the like. (C1 to d1 in FIG. 9A, r1 to s1 in FIG. 9B).
(4) When the rotary drive panel 39 rotates to a position of approximately 90 degrees with respect to the traveling rail 13 and each panel 9 reaches the second position, the linear cylinder extension limit switch 73 operates. This operation signal is input to the opening / closing control device 61, whereby a command for making the direct acting cylinder driving current zero is output from the opening / closing control device 61 to the direct acting cylinder inverter circuit 63. Stop (d1 to e1 in FIG. 9A). At this time, since there is a gap due to backlash between the panels, each panel 9 is in a slightly open state, and the rotation drive panel is not rotated or moved from the stop position. The folding operation is continued (from s1 to t1 in FIG. 9B).
(5) Each panel 9 is folded toward a completely folded state only by traveling of the traveling drive panel 31. Here, when the position of the travel drive panel 31 comes to the position where the open / deceleration limit switch 79 is installed, the open / deceleration limit switch 79 operates, an operation signal is input to the open / close control device 61, and the open / close control device 61 travels. A low command frequency is output to the traveling motor inverter circuit 65 to reduce the traveling speed of the drive panel 31. As a result, the rotational speed of the traveling motor 20 is reduced, and the traveling speed of the traveling drive panel 31 is reduced. Since the speed reduction operation is also performed by controlling the frequency of the inverter, the travel drive panel 31 can be decelerated without reducing the rotational torque of the travel motor 20, so that each panel 9 can be more closely folded (FIG. 8 (d)). FIG. 9 (b) from t1 to u1).
(6) By causing only the traveling drive panel 31 to travel at a reduced speed, each panel 9 is further folded into a completely folded state. When the travel drive panel 31 reaches the position of the open limit switch 77, the open limit switch 77 operates, an operation signal is input to the open / close control device 61, and the drive current of the travel motor 20 is supplied from the open / close control device 61. A command to make it zero is output to the inverter circuit 65 for the travel motor. As a result, the power supply to the traveling motor 20 is stopped, the traveling motor 20 is stopped, each panel is folded to the folding position, and the opening operation is completed (from u1 in FIGS. 8 (e) and 9 (b)). w1).

Next, the closing operation of the gate 5 will be described.
(1) When the close switch 69 is pressed, the closing operation is started from the open state (FIG. 10A). First, the opening / closing control device 61 outputs a signal for driving the linear cylinder 33 to the linear cylinder inverter circuit 63, whereby the rotary drive panel 39 starts moving. Initially, since each panel 9 is in a completely folded state, when the linear motion cylinder 33 is operated, each panel 9 moves in the direction of the door-end side column 1 while being folded (see FIG. 10 (b), a2 to c2 in FIG. 11 (a). By this operation, it is possible to extend each panel 9 by rotating the rotation drive panel 39 at a position where it does not hit the folding side column 3.
(2) When the linear cylinder 33 is operated for a predetermined time by a timer in the control device and each panel 9 reaches the first position, the opening / closing control device 61 directly outputs a signal for setting the drive current of the linear motion cylinder 33 to zero. Output to the moving cylinder inverter circuit 63 to stop the direct acting cylinder 33. On the other hand, like the opening operation, the opening / closing control device 61 outputs a frequency signal for driving the driving panel to the driving motor inverter circuit 65, thereby driving the driving motor 20 at a predetermined rotational speed. The traveling toward the door stop side support 1 is started. At this time, the rotation drive panel 39 does not rotate or move because the direct acting cylinder 33 is stopped, but there is a backlash between the panels. It gradually opens as it travels in the direction. (FIG. 10 (c), c2 to e2 in FIG. 11 (a), q2 to s2 in (b)). Similar to the opening operation, the first position may be detected by a limit switch or the like and input to the opening / closing control device 61.
(3) When the linear motion cylinder 33 is operated for a predetermined time by a timer in the control device and each panel 9 reaches the second position, the opening / closing control device 61 sends a signal for driving the linear motion cylinder 33 to the linear motion cylinder inverter. The output is outputted to the circuit 63, thereby driving the rotary drive panel 39 again. Thereafter, similar to the opening operation, the opening / closing control device 61 outputs a frequency signal to each inverter circuit so that the traveling speed of the traveling drive panel 31 and the rotational speed of the rotary drive panel 39 can be coordinated with each other. (FIG. 10 (d), e2 to g2 in FIG. 11 (a), and s2 to t2 in (b)).
(4) When the rotary drive panel 39 rotates to a position substantially parallel (0 degree) to the traveling rail 13 and each panel 9 reaches the third position, the limit limit switch 75 of the linear cylinder is operated. Then, like the opening operation, the direct acting cylinder 33 stops, and the rotation and travel of the rotary drive panel 39 also stop. At this time, since there is a gap due to backlash between the panels, each panel 9 is not fully extended, and the extension operation is continued only by the travel of the travel drive panel 31 (g2 in FIG. 11A). To h2, (b) t2 to u2).
(5) When the travel drive panel 31 reaches the position of the closed deceleration limit switch 83, the speed of the travel drive panel 31 is reduced as in the opening operation (from u2 to v2 in FIGS. 10 (e) and 11 (b)). ).
(6) By causing only the traveling drive panel 31 to travel at a reduced speed, each panel 9 is extended to a fully extended state. When the travel drive panel 31 reaches the position of the closed limit switch 81, the limit switch operates in the same way as the opening operation, the power supply to the travel motor 20 is stopped, the travel motor 20 stops, and each panel 9 Is deployed to the extended position. (FIG. 10 (f), v2 to x2 in FIG. 11 (b)).
(7) When the operation of the traveling motor 20 is stopped, a brake drive circuit operation signal is output from the opening / closing control device 61 to the brake drive circuit 87, and the brake drive circuit 87 is normally energized to the brake electromagnet. And the brake of the traveling motor 20 is operated. Thus, after the closing operation is completed, each panel 9 cannot be manually opened and closed, which is very effective for security.

  As described above, according to the opening / closing control device 61 of the present invention, the gate whose rotation axis is at the center of the panel can be smoothly controlled without interfering with surrounding pillars by controlling the rotation and traveling timing of the panel. It has an excellent effect that it can be opened and closed. In the final stage of opening and closing, only the traveling drive panel is decelerated, so that each panel can be folded to the extent that it almost adheres, the effective frontage dimension in the open state can be maximized, and in the closed state it is almost It can be extended on a straight line, and the gate door design can be maintained.

  In this embodiment, the travel drive panel is decelerated after the rotation operation of the rotation drive panel is stopped, but the rotation operation of the rotation drive panel is stopped after the travel drive panel is first decelerated. May be.
