By operating the control circuit by a program stored in advance, the control unit 54 displays an image of control information on the display unit 54b1 of the user interface 54b, and changes the direction of the image to the operation of the operation switch 54b2. It functions as a display inversion means that inverts accordingly.

More specifically, the display reversing means rotates the image displayed on the display unit 54b1 by approximately 180 degrees in response to the operation of the operation switch 54b2, and reverses the image upside down and left and right.
Therefore, if the operation switch 54b2 is operated when the top, bottom, left, and right of the entire winding device 50 are exchanged, the images (for example, "035") are visually recognized in the positive direction before and after the exchange. (See FIGS. 3 and 6).

It is desirable that the control unit 54, particularly the operation switch 54b2 and the display unit 54b1, be in the vicinity of the inspection port 31b from the viewpoint of maintainability and the like, and further, the horizontal cross section passing through the center of the winding body 51 is projected downward. It is preferable that it is located within the specified range.

As shown in FIG. 2, the case 54a is located on the opposite side of the switch 53 in the radial direction, and is provided so as to sandwich the fixed shaft 52 with the switch 53.
The case 54a has a main body case portion 54a2 located on one side (left side according to FIG. 2) of the virtual plane P including the center line of the fixed shaft 52 and the other side (the other side of the virtual plane P as a boundary). According to FIG. 2, it has an auxiliary case portion 54a3 located on the right side) and integrated with the main body case portion 54a2, and a lid member 54a1 that covers the front surface side of the main body case portion 54a2. A part of the outer peripheral surface of the fixed shaft 52 is covered in the circumferential direction by the case portion 54a3.

A control circuit or the like having a user interface 54b is attached to the main body case portion 54a2 and the auxiliary case portion 54a3.

The lid member 54a1 is provided with a through-hole-shaped opening 54a11, and the user interface 54b including the display portion 54b1 is exposed to the outside through the opening 54a11.

According to the case structure as described above, for example, parts for forming a control circuit can be housed in the auxiliary case portion 54a3, and the space in the winding body 51 can be effectively used. Moreover, the entire control unit 54 can be firmly fixed to the fixed shaft 52.

Further, according to the illustrated example, the user interface 54b is provided near the center of the case 54a in the vertical direction. As another example, the user interface 54b can be provided on the upper side or the lower side of the case 54a.
As shown in FIG. 3, the user interface 54b is operated from the outside by a display unit 54b1 that displays the sensitivity of an obstacle sensing device (not shown), an error code, various set values, the rotation speed of the winding body 51, and the like. It is provided with an operation switch 54b2 that mechanically self-holds the state.
Further, the user interface 54b is provided with a code display unit 54c so that the user interface 54b can be visually recognized from the outside via the display unit 54b1.

The display unit 54b1 is a 7-segment LED according to the illustrated example, and is electrically connected to a control circuit (not shown) in the case 54a. As another example of the display unit 54b1, a liquid crystal display or other display device can be used.
The display unit 54b1 is located inside the winding body 51 together with the winding device 50, and is visually recognized from the outside of the winding body 51 via the penetrating portion 51c between the rod-shaped members 51a and 51a adjacent in the circumferential direction. To.

The operation switch 54b2 is a 4-bit DIP switch according to the illustrated example, outputs a plurality of patterns of contact signals according to its on / off pattern, and inputs the contact signals to a control circuit (not shown) in the case 54a. ..
For the contact signals of the plurality of patterns, the orientation of the image displayed on the display unit 54b1 is set to the forward direction (see FIG. 3) or the reverse direction (see FIG. 6) according to the up / down / left / right directions of the winding device 50. Directives are included.

As an example, of the four switches constituting the operation switch 54b2, the switch of the first bit is a switch that reverses the direction of the image displayed on the display unit 54b1 and mechanically holds the reversed state. , Multiple switches of other bits are used for the switch to change the opening / closing speed.

The operation switch 54b2 may be any as long as it mechanically self-holds the output state of the contact signals of a plurality of patterns, and as another example, it is replaced with a rotary DIP switch or another single or a plurality of self-holding switches. It is possible.

Further, the code display unit 54c is an image that can be read by a code reading device, and can be, for example, a QR code, a bar code, or the like. The information of the code display unit 54c is information about the control unit 54 or information associated with the control unit 54.
Here, the code reading device may be any as long as it reads the code display unit 54c and displays the read information. For example, a mobile terminal in which a dedicated program is installed (specifically, a smartphone, a wristwatch-type mobile terminal, or the like). ), Or other portable readers, etc.
Further, the specific information included in the code display unit 54c is, for example, the information described in the label 54d, the detailed information not described in the label 54d, and the like, such as the operation method of the switchgear A and various errors. It may be a code explanation or the like.

In this embodiment, the information included in the code display unit 54c is directly included with the information related to the control unit 54, but as another example, the code display unit 54c is accessed by the mobile terminal or the like. Information such as the address of the server computer is included, the information associated with the control unit 54 is stored in the server computer, and the mobile terminal or the like calls in and displays the information associated with the control unit 54 from the server computer. It is also possible to make it an aspect of the above.

Further, as shown in FIG. 1, the remote controller 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 the case 44 having a rectangular shape or the like. The operation switch such as the closing switch 43 for closing the opening / closing body 10 is exposed, and wireless signals such as an opening command, a closing command, and a stop command are transmitted to the inside of the case 44 according to the operation of the switch. It is equipped with a control circuit for transmitting to 54, a transmitter, and the like.

Next, in the switchgear A having the above configuration, the action and effect when the top, bottom, left, and right of the winding device 50 are exchanged will be described (see FIGS. 4 to 6).
The switchgear A'in FIG. 4 has a left-handed configuration in which the switchgear 53, the control unit 54, and the like are arranged on the left side.

The up / down / left / right replacement of the winding device 50 is performed in the manufacturing process of the switchgear A'or at the installation site.

Specifically, the winding device 50 is set in the storage case 31 in a state where the top, bottom, left, and right are interchanged with respect to the embodiment shown in FIG. 1 (see FIGS. 4 and 5).
At this time, by manually operating the operation switch 54b2, the orientation of the image displayed on the display unit 54b1 is changed from the forward orientation (see FIG. 3) to the reverse orientation (see FIG. 6).

Then, the upper end side of the opening / closing body 10 is fastened to the winding body 51 whose top, bottom, left, and right are interchanged (see FIG. 5).

Therefore, when the inspection port 31b is opened in the fully closed state in which the opening / closing body 10 is extended from the winding device 50, the operator or the like visually recognizes an image (see FIG. 6) in the correct vertical direction on the display unit 54b1. be able to.
Therefore, it is possible to reduce that an operator or the like misunderstands an image displayed on the display unit 54b1 (for example, sensitivity of an obstacle sensing device, an error code, various set values, a rotation speed, etc.).
Moreover, since the orientation of the image displayed on the display unit 54b1 is held by the mechanical position of the operation switch 54b2, it does not disappear when the power is cut off.

Further, when the operator or the like reads the code display unit 54c with a code reading device (for example, a mobile terminal or the like), the code reading device causes the code reading device to display information about the control unit 54 or information associated with the control unit 54. Can be visually recognized.

Further, the operator or the like can visually recognize the information written on the label 54d on the back surface of the lid member 54a1 by removing the lid member 54a1.

<About the operation of the control unit>
Next, the operation of the control unit 54, specifically, the switching procedure and operation of the operation switch 54b2 will be described in more detail.

In this operation method, in the opening / closing device A having the above configuration, the penetrating portion 51c (specifically, the space between the rod-shaped members 51a and 51a adjacent in the circumferential direction) on the outer periphery of the winding body 51 is covered with the opening / closing body 10. It includes a step of making a non-exposed state and a step of performing an operation on the operation switch 54b2 after this step.

That is, in order to operate the operation switch 54b2, it is necessary to keep the operation switch 54b2 in an exposed state that can be manually operated from the outside. When the operation switch 54b2 is always exposed or the operation switch 54b2 is housed in a case or the like that can be easily released, it is relatively easy to operate the operation switch 54b2.

On the other hand, for example, when the opening / closing body 10 is fully opened or opened to some extent, the operation switch 54b2 is in a shielded state covered by the opening / closing body 10 wound around the winding body 51. In such a case, it is troublesome to expose the operation switch 54b2.
Therefore, when it is necessary to operate the operation switch 54b2, before winding the opening / closing body 10 around the winding body 51, the operation switch 54b2 in the exposed state should be operated with a switch such as a switching operation in advance. Is preferable.

For example, before shipping the switchgear A, before winding the switchgear 10 around the winder 51 at a factory or the like, a setting work (switching work) is performed on the operation switch 54b2 in advance so as to be left or right as desired. After that, the work of winding the opening / closing body 10 around the winding body 51 (including the hanging work) may be performed.
Since the operation switch 54b2 operated in this way is a self-holding switch, the state set as described above is changed to a shielded state in which the winding body 51 is wound and covered by the opening / closing body 10. Also maintain.

By the way, when the operation switch 54b2 is shielded by the opening / closing body 10 wound around the winding body 51, a switching operation for the operation switch 54b2 may be required.
For example, this corresponds to the case where it is found that the switchgear A is erroneously set in the opposite direction when the switchgear A is installed at the site. In such a case, the opening / closing body 10 is extended to some extent, for example, in a semi-closed state or a fully closed state, the operation switch 54b2 is exposed, and a switching operation is performed on the operation switch 54b2. After that, the normal opening / closing operation may be performed.

Depending on the switchgear A, even if the switchgear 10 is extended to the fully closed state, it is still a part of the switchgear 10 (including a case where it is different from a metal slats such as a flexible material such as a flexible sheet). However, there are cases where the operation switch 54b2 remains around the winding body 51 (in a so-called discarded winding state) and is shielded. In such a case, even after it is fully closed, the opening / closing body 10 is further extended by manual or forced closing operation, and a part of the opening / closing body 10 around the winding body 51 is extended to expose the operation switch 54b2. Then, a switching operation may be performed on the operation switch 54b2, and then the original normal opening / closing operation may be performed.

As described above, it is inconvenient from the viewpoint of switching and operating the operation switch 54b2 that the operation switch 54b2 is shielded by the opening / closing body 10 wound around the winding body 51, but on the other hand, it is shielded. As a result, the operation switch 54b2 can be protected from dust, impact, and the like, and it can be expected that the operation switch 54b2 is also protected from unconscious or unjust intentional switching operations.

<Other variants>
According to the above embodiment, the orientation of the image of the display unit 54b1 is switched by manual operation with the operation switch 54b2, but as another preferable example, the winding device 50 is oriented in the forward direction or in the reverse direction. It is equipped with a posture sensing unit (for example, a posture sensor, a limit switch, etc.) that detects whether or not the image is, and the control unit 54 automatically orients the image displayed on the display unit 54b1 according to the sensing signal of the posture sensing unit. It is also possible to make the orientation appropriate.

Further, according to the above embodiment, the display unit 54b1 displays the common image upside down before and after the inversion, but as another preferable example, the image before the inversion and after the inversion. The mode of itself may be different.
For example, when the image is a character, the font or typeface may be changed by changing the italic, bold, and fine characters before and after inversion. Further, as another example, the display color of the image may be changed before and after the inversion.
By doing so, it is possible to easily make a third party who visually recognizes the image recognize whether or not the display inversion means has been operated.

Further, in the above embodiment, when the right-handed hand and the left-handed hand are changed, it is preferable that the winding device 50 can be used in common as it is without any change in other configurations except that the upper, lower, left and right sides are exchanged. , May have some elements that change slightly. For example, if the bearing brackets that receive the fixed shaft 52 have different structures on the left and right, the end structure of the take-up device 50 may be changed, or parts such as hole positions and hanging sources for attaching the opening / closing body 10 may be changed. May be changed or the like.

Further, according to the above embodiment, the orientation of the image displayed on the display unit 54b1 is set by the operation switch 54b2, but as another example, an instruction by the remote control device 40 or a wired opening / closing stop (not shown) is used. The orientation of the image may be set by an instruction or the like by a special operation (for example, multiple pressing operation) with the switch.

In the above embodiment, the image displayed on the display unit 54b1 is a number of two digits or more, and the whole number of the two digits or more is inverted (in other words, the whole is approximately 180 rotations). (See FIGS. 3 and 6), it is preferable that when the image is inverted, at least a part thereof is turned upside down so that the display shape is different from that before the inversion. In other words, it is preferable that the image is not an image having only a vertically symmetrical display shape.
For example, the image can be a single digit number that has a different display shape when flipped vertically and horizontally.
Further, the image may have two or more lines of characters having different display shapes when inverted vertically and horizontally.

Further, according to the above embodiment, the penetrating portion 51c is used as a space between the rod-shaped members 51a and 51a adjacent to each other in the circumferential direction, but as another example, the winding body is formed into a cylindrical shape and the winding body is formed. It is also possible to use a hole or a notch formed in the peripheral wall of the above as the penetration portion.

Further, the present invention is not limited to the above-described embodiment, and can be appropriately changed without changing the gist of the present invention.
