Description

The present invention relates to an opening/closing device, such as a shutter device, an overhead door, a roll blind device, or the like, which partitions a space and closes an opening/closing body.

2. Description of the Related Art Conventionally, an opening/closing device of this type, as described in, for example, Patent Document 1, includes an opening/closing body that performs a closing operation so as to partition an opening of a garage, and a winding/unwinding of the opening/closing body on the opening direction side. There is a shutter device for a garage provided with a driving section for opening and a control circuit for controlling this driving section.
Such an opening/closing device is required to open the opening/closing body at a high speed without making the user wait, and to fully close the opening/closing body quickly during the closing operation from the viewpoint of crime prevention. However, if the opening/closing member is simply opened/closed at a high speed, noise and vibration may increase significantly, so it is preferable to set the opening/closing speed of the opening/closing member to an appropriate speed that is not too fast.

However, even if the rotation speed of the winding body is set at a certain speed in consideration of the above situation, noise and vibration may increase significantly depending on the installation conditions and usability of the switchgear. Conversely, the opening and closing speed may decrease, impairing the good feeling of use.

For this reason, in the former case, the concave portion is slightly fitted to the outer peripheral surface of the winding body, the winding diameter of the opening/closing body is reduced, and the opening/closing speed may be excessively decreased accordingly. In the latter case, the convex portion on the back side of the concave portion abuts against the outer peripheral surface of the winding body, increasing the winding diameter of the opening/closing body, which may result in an excessively slow opening speed. be.
Therefore, it is desirable to open and close the opening and closing body at an appropriate speed according to the installation situation and usability of the opening and closing device.

Further, in the outward winding specification, the concave portion 11b of the slat 11 is directed radially outward, and the opening/closing body 10 is wound around the winding body 32 (see FIG. 3).

Whether the opening/closing device A should be of the inner winding specification or the outer winding specification is appropriately determined depending on the situation at the site. For example, in the opening/closing device A illustrated in FIG. 2, the storage unit 30 is attached to the wall surface of the indoor side of a garage or the like, and the convex portion 11c of each slat 11 is directed to the outdoor side so as to form an inward winding specification. be done.
In addition, in the opening/closing device A shown in FIG. 3, the storage unit 30 is attached to the outdoor side wall surface of a garage or the like, and the protruding portion 11c of each slat 11 is directed to the outdoor side so that the opening and closing device A is configured to have an outward winding specification. be.

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

The storage unit 30 includes a storage case 31, a winding body 32 for winding and unwinding the opening/closing body 10, a fixed shaft 33 for rotatably supporting the winding body 32 from the inside thereof, 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 switch and control the rotation speed of the opening/closing device 34 between a plurality of speeds.

The storage case 31 is a hollow box-shaped member elongated in the width direction of the opening/closing body, and has an opening 31a elongated in the width direction of the opening/closing body on its lower wall surface. is inserted. As another example, the storage case 31 may be formed in a frame shape without wall surfaces.

An inspection opening 31b is also provided on the lower wall surface of the storage case 31 to be opened and closed by attaching and detaching the cover member.
The inspection opening 31b is positioned below the control unit 35, and is formed in a size that allows passage of the opener 34, the control unit 35, and the like.
Therefore, if the inspection opening 31b is opened with the opening/closing member 10 extended to some extent, it is possible to easily operate the control unit 35 and perform maintenance work on the opening/closing device 34 and the control unit 35.

The winding body 32 includes a plurality of rod-shaped members 32a arranged substantially parallel to each other at intervals in the circumferential direction around the fixed shaft 33, and spaced apart in the width direction of the opening/closing body so as to support the rod-shaped members 32a. It has a plurality of support plates 32 b placed side by side, and is configured in a substantially cylindrical basket shape rotatable around a fixed shaft 33 .

Each rod-like member 32a is made of a hard material such as metal and has an elongated shaft shape or cylindrical shape. The plurality of rod-like members 32a are positioned at approximately the same radial distance from the center of the fixed shaft 33. As shown in FIG. A space between the two rod-shaped members 32a, 32a adjacent in the circumferential direction functions as a through portion that ensures visibility of a user interface 35b of the control unit 35, which will be described later.

The support plate 32b is a substantially disk-shaped member that supports the rod-shaped member 32a by fitting the support plate 32b to its outer peripheral portion, and the central portion thereof is rotatably supported with respect to the fixed shaft 33 via a bearing or the like.

The fixed shaft 33 is made of a hard material such as metal and has a long cylindrical or columnar shape. fixed non-rotatably to the

The opening/closing machine 34 is a DC or AC rotary electric motor whose rotational speed is switchable, and is fixedly supported by the fixed shaft 33 with its output rotary shaft substantially parallel to the fixed shaft 33 .
The rotational force of the output rotary shaft of the opening/closing device 34 is transmitted to the winding body 32 by the driving rotary portion 34a.
The opening/closing machine 34 rotates while being switched to a plurality of types of rotation speeds including a first rotation speed and a second rotation speed according to a command from the control unit 35 .
As a means for changing the rotation speed of the switch 34, for example, a well-known speed control circuit such as an inverter or other power waveform conversion circuit may be used.

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

The control unit 35 includes a control circuit including a microcomputer, a relay, a storage device, a wireless receiver, etc. inside the case 35a, and exposes a user interface 35b 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 rotation speed corresponding to the inner winding specification and a second rotation speed corresponding to the outer winding specification. to a plurality of rotational speeds, including The first rotation speed is set higher than the second rotation speed.
From the viewpoint of maintainability, it is desirable that the control unit 35, particularly the operation switch 35b1, be located near the inspection opening 31b. preferably located.

As shown in FIGS. 2 and 3, the case 35a is provided on the opposite side of the opening/closing device 34 in the radial direction, with the fixed shaft 33 interposed therebetween.

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), A display device 35b2 for displaying error codes, various set values, and the like is provided.

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

The operation switch 35b1 may be one that mechanically self-holds the output states of the contact signals of a plurality of patterns, and as another example, a rotary DIP switch or other single or multiple self-holding switches may be used. It 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) inside the case 35a.
Other examples of the display device 35b2 include a liquid crystal display and other display devices.

Here, the above-described first rotation speed and second rotation speed will be described in detail.
In the above-described inward winding specification, as shown in FIG. 2, the opening/closing body 10 is wound around the winding body 32 with the concave portions 11b of the slats 11 facing radially inward.
Therefore, due to the fitting between the outer peripheral portion of the winding body 32 and the recessed portion 11b around it, the fitting between the outer peripheral portion of the opening/closing body 10 wound around the winding body 32 and the recessed portion 11b around it, and the like, The winding outer diameter D1 of the entire opening/closing body 10 becomes relatively small.

On the other hand, in the outer winding specification, as shown in FIG. The outer winding diameter D2 of the opening/closing body 10 as a whole becomes larger than in the case of the inner winding specification due to the contact between the portion and the protruding portion 11c around it.

Therefore, if the winding body 32 is rotated in two ways, the inner winding specification and the outer winding specification, the opening and closing speed of the opening and closing body 10 (the speed at which each slat 11 moves upward or downward) The specification is smaller than the outer winding specification.
Therefore, in the opening/closing device A of the present embodiment, the opening/closing device 34 is adapted to the inner winding specification so that the opening/closing speed of the opening/closing member 10 is substantially the same in the case of the inner winding specification and the outer winding specification. A first rotation speed and a second rotation speed corresponding to the outer winding specification are set. These first rotation speed and 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 patterns of the operation switch 35b1. .
Then, the control unit 35 recognizes the ON/OFF pattern of the operation switch 35b1, calls the rotation speed associated with this ON/OFF pattern, and operates the opening/closing device 34 at this rotation speed when an opening command or closing command is given. Rotate in the opening direction or the closing direction (see steps S1 and 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 up the pre-stored first rotation speed, and when there is an open command or a close command, the first The opener 34 is driven to rotate at one rotational speed.
Further, 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 up the second rotation speed stored in advance, and when there is an open command or a close command, Then, the opener 34 is driven to rotate at the second rotational speed.

Further, 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 previously stored rotation speed. , when there is an open command or a close command, the switch 34 is driven to rotate at the other rotational speed.
Here, the other rotational speed is set, for example, to a speed higher than the above-described first and second rotational speeds.

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 or the like. , exposing operation switches such as the close switch 43 for closing the opening/closing body 10, and transmitting wireless signals such as an open command, a close command, and a stop command within the case 44 according to the operation of the switch. It is equipped with a circuit, a transmitter, and the like.

Therefore, according to the opening/closing device A configured as described above, the rotation speed of the opening/closing device 34 and the winding body 32 can be changed by setting the operation switch 35b1. The opening/closing body 10 is opened/closed at an appropriate speed.
In particular, according to a preferred example of the present embodiment, it is possible to switch between a first rotation speed corresponding to the inner winding specification and a second rotation speed corresponding to the outer winding specification, and the first rotation speed can be switched. By making the rotation 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 to be substantially the same speed. Therefore, the vibration and noise during the opening and closing operations can be made substantially the same for these two types of specifications.

<Regarding the 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 opening/closing member 10 covers the through portion of the outer periphery of the winding body 32 (specifically, the space between the rod-shaped members 32a and 32a adjacent in the circumferential direction). and a step of performing a switching operation on the operation switch 35b1 after this step.

That is, in order to operate the operation switch 35b1, the operation switch 35b1 needs to be exposed so that it can be operated by hand or the like from the outside. When the operation switch 35b1 is always exposed or when the operation switch 35b1 is housed in a case or the like 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 shielded state where it is 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 it is necessary to operate the operation switch 35b1, before winding the opening/closing body 10 around the winding body 32, the operation switch 35b1 in the exposed state should be operated in advance such as switching work. is preferred.

For example, before the switchgear A is shipped, the operation switch 35b1 is set (switched) in advance so that the rotation speed is appropriate before the switchgear 10 is wound around the winding body 32 at a factory or the like. , the work of winding the opening/closing body 10 onto the winding body 32 (hanging work) may be performed.
Since the operation switch 35b1 operated in this manner is a self-holding switch, the state set as described above is maintained after the winding body 32 is wound and covered by the opening/closing body 10 to become the shielding state. also maintain.

By the way, when the operation switch 35b1 is shielded by the opening/closing body 10 wound around the winding body 32, the operation switch 35b1 may need to be switched.
For example, when it is found that the inner winding specification and the outer winding specification have been erroneously set in reverse at the stage when the switchgear A is installed at the site, or the length of the opening/closing body 10 in the opening/closing direction is reduced due to long-term use. Appropriate rotation speed (winding, rewinding speed) from multiple speeds (not only two speeds of inner winding and outer winding, but also three or more speeds) in case of change etc. requires an operation to switch to
In such a case, the opening/closing member 10 is extended to some extent, for example, in a half-closed state or a fully-closed state, and the operation switch 35b1 is exposed, and a switching operation is performed on the operation switch 35b1. and then the normal opening/closing operation can be performed.

Depending on the opening/closing device A, even if the opening/closing body 10 is extended to the fully closed state, the opening/closing body 10 is still part of the opening/closing body 10 (for example, it may be made of a flexible material such as a flexible sheet that is different from the metal slat). However, there is a case where the operation switch 35b1 remains around the winding body 32 (in a so-called idle winding state) and the operation switch 35b1 is blocked. In such a case, even after being fully closed, 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, the operation switch 35b1 is switched, and then the original normal opening/closing operation is enabled.

As described above, the fact that the operating switch 35b1 is shielded by the opening/closing body 10 wound around the winding body 32 is inconvenient from the viewpoint of the switching operation of the operating switch 35b1. As a result, the operation switch 35b1 can be protected from dust, shocks, and the like, and it can be expected to protect the operation switch 35b1 from unintentional or intentional switching operations.

<About other modifications>
According to the above embodiment, the winding body 32 is configured in a basket shape having a plurality of rod-like members 32a, but as another example of the winding body 32, it is also possible to configure it in a hollow cylindrical shape. be. In this case, preferably, a through-hole is provided in the peripheral wall of the cylindrical winding body so that the user interface 35b can be visually recognized from the outside in the radial direction.

Further, according to the above-described embodiment, the opening/closing body 10 is composed of a plurality of slats. It is possible to adopt a mode consisting of a net-like material, or a mode in which slats, panels, pipes, sheet-like materials, net-like materials, etc. are appropriately combined.
Even when the opening/closing body 10 includes members other than the slats, the diameter of the opening/closing body 10 wound around the winding body 32 may change. 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 can be switched by the operation switch 35b1 as necessary.

Further, according to the above embodiment, the rotational speed of the opening/closing device 34 is switched according to the state of the manually operated operation switch 35b1. It is also possible to detect by a sensor whether it is used in the outer winding specification, and automatically switch the rotation speed of the opening/closing device 34 according to the signal of this sensor.

Moreover, the present invention is not limited to the embodiments described above, and can be modified as appropriate without changing the gist of the present invention.
