Description

  The present invention relates to an opening / closing device that closes an opening / closing body so as to partition a space, such as a shutter device, an overhead door, and a roll blind device.

Conventionally, this type of opening / closing device is disclosed in, for example, Patent Document 1, an opening / closing body that performs a closing operation by partitioning an opening portion of a garage, and winding or unwinding the opening / closing body on its opening direction side. There is a garage shutter device that includes a driving unit that controls the driving unit and a control circuit that controls the driving unit.
In such an opening / closing apparatus, it is required to quickly fully close the opening / closing body from the viewpoint of crime prevention, etc. even during the closing operation without opening the opening / closing body at high speed and waiting for the user. However, when the opening / closing body is simply opened / closed at high speed, noise and vibration may be remarkably increased. Therefore, the opening / closing speed of the opening / closing body is preferably set to an appropriate speed that is not too fast.

JP 2011-220052 A

However, in consideration of the situation as described above, even when the rotational speed of the winding body is set to a certain speed, the noise and vibration are remarkably increased depending on the installation situation and usability of the switchgear.

In the latter case, the opening / closing body composed of a plurality of slats with the concave portions facing the indoor side is arranged on the indoor side with respect to the winding body located outside the garage. The opening / closing body is wound around the winding body so that the concave portion faces the outside in the radial direction and opens.
For this reason, in the former case, the concave portion slightly fits on the outer peripheral surface of the winding body, and the winding diameter of the opening / closing body becomes small, and accordingly, the opening / closing speed may become too small. In the latter case, the convex part on the back side with respect to the concave part comes into contact with the outer peripheral surface of the winding body, and the winding diameter of the opening / closing body becomes large, and accordingly the opening speed may be too high. is there.
Therefore, it is desired to open and close the opening / closing body at an appropriate speed in accordance with the installation status and usability of the opening / closing device.

<Specific Embodiment>
Next, specific embodiments having the above characteristics will be described in detail with reference to the drawings.
In the present specification, the “opening / closing body thickness direction” means the thickness direction of the opening / closing body in the closed state. In the present specification, the “opening / closing body width direction” means a direction substantially orthogonal to the opening / closing direction of the opening / closing body and not the thickness direction of the opening / closing body. In the present specification, the “opening / closing body opening / closing direction” means a direction in which the opening / closing body slides to partition or open the space.

  As shown in FIG. 1, the opening / closing device A includes an opening / closing body 10 that performs a closing operation so as to partition a space, a guide rail 20 that guides the opening / closing body on both sides in the width direction, and an opening / closing body 10. A storage unit 30 that stores and feeds in the open direction side and a remote control device 40 that remotely controls the opening / closing device A wirelessly are provided. (See FIG. 3).

  The opening / closing body 10 includes an opening / closing body main body 10a formed by connecting a plurality of slats 11 formed by bending a horizontally-long substantially rectangular metal plate so as to rotate between the upper and lower adjacent slats, and the opening / closing body main body. A seat plate member 10b that is connected to a closing direction end of 10a and abuts against a contact target portion when fully closed, and that has upper ends of a plurality of slats 11 fixed to an outer peripheral portion of the winding body 32. Yes.

Each slat 11 has one surface in the thickness direction (left side according to FIG. 2) formed in a substantially concave shape in the longitudinal section, and the opposite surface is formed in a convex shape in the longitudinal section. Is continuous in the width direction of the opening and closing body.
Therefore, as shown in FIGS. 2 and 3, each slat 11 has a concave portion 11b on one surface in the thickness direction, and a convex surface is formed on the other surface which is the back side of the concave portion 11b. It has the shape part 11c.

  In addition, curled portions 11a are formed on one end side and the other end side of each slat 11 in the opening and closing direction. The curled portion 11 a engages between two adjacent slats 11, 11, and allows one of the slats 11 to rotate in both directions with respect to the other slat 11.

  In the inner winding specification, the concave portion 11b of the slat 11 is directed radially inward, and the opening / closing body 10 is wound around the winding body 32 (see FIG. 2). Moreover, in the said external winding specification, the recessed part 11b of the slat 11 is orient | assigned to the radial direction outer side, and the opening / closing body 10 is wound around the winding body 32 (refer FIG. 3).

Whether the opening / closing device A has an internal winding specification or an external winding specification is appropriately determined depending on the situation at the site. For example, the opening / closing device A illustrated in FIG. 2 is configured to be internally wound so that the storage portion 30 is mounted on a wall surface on the indoor side such as a garage and the convex portions 11c of the slats 11 are directed outward. Is done.
In addition, the opening / closing device A shown in FIG. 3 is configured to have an external winding specification in which the storage portion 30 is mounted on an outdoor-side wall surface such as a garage and the convex portions 11c of the slats 11 are directed outward. The

  The guide rails 20 are provided on both sides in the opening / closing body width direction. Each guide rail 20 surrounds the end in the width direction of the opening / closing body 10 in a concave shape in the cross section and guides it in the opening / closing direction.

  The storage unit 30 includes a winding body 32 that winds and unwinds the opening / closing body 10 in a storage case 31, a fixed shaft 33 that rotatably supports the winding body 32 from the inside, and a fixed shaft. An opening / closing device 34 that is integrally supported by 33 and transmits a rotational force to the winding body 32, and a control unit 35 that can be controlled by switching the rotation speed of the opening / closing device 34 to a plurality of speeds.

  The storage case 31 is a hollow box-like member that is long in the opening / closing body width direction, and has an opening 31a that is long in the opening / closing body width direction on the lower side wall surface. Is inserted. In addition, as another example of this storage case 31, it is also possible to form in the frame shape which does not have a wall surface.

An inspection port 31b that is opened and closed by attaching and detaching the lid member is also provided on the lower side wall surface of the storage case 31.
The inspection port 31b is located on the lower side of the control unit 35, and is formed to a size that can pass through the switch 34, the control unit 35, and the like.
Therefore, if the inspection port 31b is opened with the opening / closing body 10 extended to some extent, the operation to the control unit 35, the maintenance work for the opening / closing machine 34 and the control unit 35, and the like can be easily performed.

  The winding body 32 has a plurality of rod-like members 32a disposed around the fixed shaft 33 in the circumferential direction and spaced substantially in parallel, and the gaps in the opening / closing body width direction so as to support the rod-like members 32a. And a plurality of support plates 32 b provided to be arranged, and is configured in a substantially cylindrical bowl shape that can rotate around the fixed shaft 33.

  Each rod-shaped member 32a is formed in a long shaft shape or a cylindrical shape from a hard material such as metal. The plurality of rod-shaped members 32 a are located at a distance of substantially the same radius from the center portion of the fixed shaft 33. The space between the two rod-shaped members 32a and 32a adjacent to each other in the circumferential direction functions as a penetrating portion that ensures the visibility of a user interface 35b of the control unit 35 described later.

  The support plate 32b is a substantially disk-like member that fits and supports the rod-like member 32a on the outer peripheral portion, and the center side thereof is rotatably supported with respect to the fixed shaft 33 via a bearing or the like.

  The fixed shaft 33 is formed of a hard material such as metal into a long cylindrical or columnar shape, and is inserted into the central portion of the winding body 32. Both ends of the fixed shaft 33 are inserted into the storage case 31 via brackets (not shown). It is fixed so that it cannot rotate.

The opening / closing machine 34 is a direct current or alternating current rotary electric motor whose rotation speed can be switched, and is fixedly supported by the fixed shaft 33 with its output rotation shaft substantially parallel to the fixed shaft 33.
The rotational force of the output rotation shaft of the opening / closing machine 34 is transmitted to the winding body 32 by the drive rotation unit 34a.
In response to a command from the control unit 35, the switch 34 is switched to a plurality of types of rotation speeds including the first rotation speed and the second rotation speed and rotates.
As a means for changing the rotation speed of the switch 34, for example, a known speed control circuit such as an inverter or other power waveform conversion circuit may be used.

The drive rotating part 34a is a substantially disk-like member in which a rod-like member 32a is fitted and fixed to the outer peripheral part, and the center side thereof is supported rotatably with respect to the fixed shaft 33 via a bearing or the like. The rotational force of the opening / closing machine 34 is transmitted to the drive rotation unit 34a via a plurality of gears (not shown).
Therefore, when the output rotation shaft of the opening / closing device 34 rotates, the winding body 32 rotates by the rotational force.

The control unit 35 includes a control circuit in which a microcomputer, a relay, a storage device, a wireless receiver, and the like are provided in the case 35a, and the user interface 35b is exposed outside the case 35a.
The control unit 35 causes the control circuit to function according to a program stored in advance so that the speed of the opening / closing device 34 is set to a first rotational speed corresponding to the inner winding specification and a second corresponding to the outer winding specification. Are switched to a plurality of rotation speeds including The first rotation speed is set to be higher than the second rotation speed.
The control unit 35, particularly the operation switch 35 b 1, is desirably located near the inspection port 31 b from the viewpoint of maintainability and the like, and further, within a range in which a horizontal section passing through the center of the winding body 32 is projected downward. Preferably it is located.

  As shown in FIGS. 2 and 3, the case 35 a is provided on the opposite side of the switch 34 in the radial direction so that the fixed shaft 33 is sandwiched between the case 35 a and the switch 34.

The user interface 35b is provided near the lower end of the case 35a.
As shown in FIG. 4, the user interface 35b includes an operation switch 35b1 that mechanically self-holds output states of different rotational speed commands, the rotational speed of the winding body 32, the sensitivity of an obstacle sensing device (not shown), And a display device 35b2 for displaying error codes, various set values, and the like.

According to the illustrated example, the operation switch 35b1 is a 4-bit dip switch, and can output a plurality of patterns of contact signals according to the on / off pattern.
The operation switch 35b1 is electrically connected to a control circuit (not shown) in the case 35a.

  The operation switch 35b1 may be anything that mechanically self-holds the output state of the contact signals of a plurality of patterns. As another example, a rotary dip switch or other single or plural self-holding switches may be used. Is possible.

The display device 35b2 is a 7-segment LED according to the illustrated example, and is electrically connected to a control circuit (not shown) in the case 35a.
Other examples of the display device 35b2 may be a liquid crystal display or other display devices.

Here, the first rotation speed and the second rotation speed described above will be described in detail.
In the above-described inner winding specification, as shown in FIG. 2, the opening / closing body 10 is wound around the winding body 32 with the concave portion 11 b of each slat 11 facing inward in the radial direction.
Therefore, the fitting between the outer peripheral part of the winding body 32 and the surrounding concave part 11b, the fitting between the outer peripheral part of the opening / closing body 10 wound around the winding body 32 and the surrounding concave part 11b, etc. The winding outer diameter D1 of the entire opening / closing body 10 is relatively small.

  On the other hand, in the outer winding specification, as shown in FIG. 3, the outer periphery of the winding body 32 and the surrounding convex portion 11 c are in contact with each other, and the outer periphery of the opening / closing body 10 wound around the winding body 32. The winding outer diameter D2 of the entire opening / closing body 10 becomes larger than that in the case of the inner winding specification due to contact between the portion and the surrounding convex portion 11c.

For this reason, if the winding body 32 is rotated in two ways of an inner winding specification and an outer winding specification, the opening / closing speed of the opening / closing body 10 (the speed at which each slat 11 moves upward or downward) The specification is smaller than the external winding specification.
Therefore, in the opening / closing device A of the present embodiment, the opening / closing body 10 corresponds to the inner winding specification so that the opening / closing speed of the opening / closing body 10 is substantially the same between the case of the inner winding specification and the case of the outer winding specification. A first rotation speed and a second rotation speed corresponding to the outer winding specification are set. The first rotation speed and the second rotation speed can be switched by operating the operation switch 35b1.

More specifically, the control unit 35 stores in advance a plurality of types of rotation speeds including the first rotation speed and the second rotation speed described above in association with the on / off pattern of the operation switch 35b1. .
And the control part 35 recognizes the on / off pattern of the operation switch 35b1, calls the rotational speed associated with this on / off pattern, and when there is an opening command or a closing command, the controller 34 is operated at this rotational speed. It is rotated in the opening direction or the closing direction (see steps S1 to S2 in FIG. 5).

For example, if the ON / OFF pattern of the operation switch 35b1 corresponds to the first rotation speed, the control unit 35 calls the first rotation speed stored in advance, and when there is an opening command or a closing command, The switch 34 is driven to rotate at a single rotational speed.
If the on / off pattern of the operation switch 35b1 is switched to one corresponding to the second rotation speed, the control unit 35 calls the second rotation speed stored in advance, and when there is an opening command or a closing command. In addition, the switch 34 is driven to rotate at the second rotational speed.

If the on / off pattern of the operation switch 35b1 is switched to one corresponding to a rotation speed other than the first and second rotation speeds, the control unit 35 calls the other rotation speed stored in advance. When the opening command or the closing command is issued, the switch 34 is driven to rotate at the other rotational speed.
Here, for example, the other rotation speed is set to a speed higher than the first and second rotation speeds described above.

  As shown in FIG. 1, the remote control device 40 has an open switch 41 for opening the opening / closing body 10 and a stop switch 42 for stopping the operation of the opening / closing body 10 on the surface of a rectangular case 44. A control for exposing the operation switch such as the closing switch 43 for closing the opening / closing body 10 and transmitting a radio signal such as an opening command, a closing command, or a stop command in the case 44 according to the operation of the switch. A circuit and a transmitter are provided.

Therefore, according to the opening / closing device A having the above-described configuration, the rotation speed of the opening / closing machine 34 and the winding body 32 can be changed by setting the operation switch 35b1, and as a result, depending on the installation status and usability of the opening / closing device. The opening / closing body 10 is opened / closed at an appropriate speed.
In particular, according to a preferred example of the present embodiment, the first rotation speed corresponding to the inner winding specification and the second rotation speed corresponding to the outer winding specification can be switched, and the first rotation speed is changed. By making the speed higher than the second rotation speed, the opening / closing speed of the opening / closing body 10 in the case of the inner winding specification and the opening / closing speed of the opening / closing body 10 in the case of the outer winding specification are made substantially the same. Therefore, the vibration and noise during the opening / closing operation in these two types of specifications can be made substantially the same.

<About speed switching method>
Next, the speed switching method of the opening / closing device A will be described in more detail.

  In this speed switching method, in the opening / closing device A configured as described above, the through-hole portion on the outer periphery of the winding body 32 (specifically, the space between the rod-shaped members 32a and 32a adjacent in the circumferential direction) is covered with the opening / closing body 10. And a step of switching the operation switch 35b1 after this step.

  That is, in order to operate the operation switch 35b1, it is necessary to leave the operation switch 35b1 in an exposed state that can be operated by hand or the like from the outside. When the operation switch 35b1 is always exposed or the operation switch 35b1 is housed in a case that can be easily released, it is relatively easy to operate the operation switch 35b1.

On the other hand, for example, when the opening / closing body 10 is fully opened or opened to some extent, the operation switch 35b1 is in a shielding state covered by the opening / closing body 10 wound around the winding body 32. In such a case, it is troublesome to expose the operation switch 35b1.
Therefore, when the operation switch 35b1 is required to be operated, before the opening / closing body 10 is wound around the winding body 32, a switch operation such as a switching operation is performed in advance on the operation switch 35b1 in the exposed state. Is preferred.

For example, before the opening / closing device A is shipped, a setting operation (switching operation) is performed on the operation switch 35b1 in advance so that the opening / closing body 10 is wound around the winding body 32 at a factory or the like so as to have an appropriate rotation speed. The operation of winding the opening / closing body 10 around the winding body 32 (hanging operation) may be performed.
Since the operation switch 35b1 operated in this way is a self-holding switch, the state set as described above is changed to the shield state in which the winding body 32 is wound and covered by the opening / closing body 10. Also maintain.

By the way, when the operation switch 35b1 is shielded by the opening / closing body 10 wound around the winding body 32, a switching operation may be required for the operation switch 35b1.
For example, when it is found that the inner winding specification and the outer winding specification are set in reverse at the stage when the opening / closing device A is installed on the site, or the length of the opening / closing body 10 in the opening / closing direction is increased due to aging. Appropriate rotation speed (winding / rewinding speed) from a plurality of speeds (including not only two speeds of inner winding and outer winding but also three or more speeds) The operation to switch to is required.
In such a case, the opening / closing body 10 is extended to some extent, for example, in a half-closed state or a fully-closed state, the operation switch 35b1 is exposed, and a switching operation is performed on the operation switch 35b1. And a normal opening / closing operation may be performed thereafter.

  Note that, depending on the opening / closing device A, even if the opening / closing body 10 is fully extended, a part of the opening / closing body 10 is still included (including cases where the opening / closing body 10 is different from a metal slat such as a flexible material such as a flexible sheet). However, there are cases where the operation switch 35b1 remains around the winding body 32 (in a so-called discarded winding state) and is shielded. In such a case, even after the fully closed state, the opening / closing body 10 is further extended manually or by a forced closing operation, and a part of the opening / closing body 10 around the winding body 32 is extended to expose the operation switch 35b1. Then, a switching operation is performed on the operation switch 35b1, and then the original normal opening / closing operation can be performed.

  As described above, the fact that the operation switch 35b1 is shielded by the opening / closing body 10 wound around the winding body 32 is inconvenient in terms of switching operation of the operation switch 35b1, but is shielded. Thus, it can be expected that the operation switch 35b1 can be protected from dust, impact, and the like, and further, the operation switch 35b1 can be protected from unconscious or unintentional switching operation.

<About other modifications>
According to the said embodiment, although the winding body 32 was comprised in the bowl shape which has the some rod-shaped member 32a, as an other example of the winding body 32, it is also possible to comprise inside a hollow cylindrical shape. is there. In this case, it is preferable that a penetration portion that makes the user interface 35b visible from the outside in the radial direction is provided on the peripheral wall of the cylindrical winding body.

Moreover, according to the said embodiment, although the opening / closing body 10 was comprised with several slats, as another example of the opening / closing body 10, the aspect formed by connecting a panel, a pipe, etc. in the opening / closing direction, a sheet-like thing, It is possible to adopt a mode composed of a net-like material, or a mode in which slats, panels, pipes, sheet-like materials, net-like materials and the like are appropriately combined.
As described above, even when the opening / closing body 10 includes a member other than the slat, the diameter of the opening / closing body 10 wound around the winding body 32 may change. Therefore, speed switching using the operation switch 35b1 is possible. Useful.
Furthermore, when the opening / closing body 10 is replaced or changed to another new opening / closing body 10 due to maintenance, renovation, or the like, the speed may be switched by the operation switch 35b1 as necessary.

  Moreover, according to the said embodiment, although the rotational speed of the switch 34 was switched according to the state of the operation switch 35b1 operated manually, as another example, the said switchgear A is used by an internal winding specification. It is also possible to detect whether it is used in the external winding specification with a sensor, and to automatically switch the rotation speed of the switch 34 in accordance with the signal of this sensor.

  Moreover, this invention is not limited to the embodiment mentioned above, In the range which does not change the summary of this invention, it can change suitably.
