Description

[Technical Field]

[0001] The present invention relates to a detection means installation structure. [Background technology]

[0002] One conventional technology for detecting irregular winding of a shutter curtain that constitutes a shutter device installed at an opening in a building (abnormal swelling of the shutter curtain when the shutter curtain is wound up or unwound) involves installing an overrun detection device inside a storage section fixed to the building structure so that the detection lever of the overrun detection device is positioned on the opposite side of the building structure from the shutter curtain.If the shutter curtain becomes irregularly wound toward the opposite side of the building structure, the detection lever will come into contact with the shutter curtain, causing the overrun detection device to detect the irregular winding of the shutter curtain and send out a detection signal (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 07-301068 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional technology, as described above, the overrun detection device is installed inside the storage section so that the detection lever of the overrun detection device is located on the opposite side of the shutter curtain from the main body. Therefore, if the shutter curtain becomes irregularly wound toward the main body, for example, the detection lever of the overrun detection device is unlikely to come into contact with the shutter curtain, which may make it difficult to detect the irregularity early. Therefore, there is a risk that harm (e.g., damage to the opening / closing body) may occur due to irregular winding of the opening / closing body, making it difficult to ensure safety when using the shutter device. Therefore, there is room for improvement from the perspective of increasing safety when using opening / closing devices such as shutter devices.

[0005] The present invention has been made to solve the problems in the prior art, and has an object to provide an installation structure for a detection means that can improve safety when using a switching device. [Means for solving the problem]

[0007] The detection means installation structure according to claim 2 is the detection means installation structure according to claim 1, wherein the detection means is configured so that the longitudinal direction of the detection body is aligned with the opening / closing direction of the opening / closing body.

[0008] The installation structure of the detection means described in claim 3 is the installation structure of the detection means described in claim 1 or 2, in which the detection means is configured so that the tip of the detection body is located on the other side of either the opening direction or closing direction of the opening / closing body relative to the axis of the winding shaft for moving the opening / closing body open and closed.

[0009] The installation structure of the detection means described in claim 4 is the installation structure of the detection means described in claim 1 or 2, in which the main body portion is arranged at the end of the storage means on the opening direction side of the opening / closing body or at a position nearby, and the detection means is provided so that the detection body protrudes from the main body portion toward the closing direction side of the opening / closing body.

[0011] The detection means installation structure described in claim 6 is the detection means installation structure described in claim 5, wherein the storage means is a notch provided in the case plate, and includes a notch that allows wiring connected to the detection means to be inserted through the notch.

[0012] The installation structure for a detection means described in claim 7 is the installation structure for a detection means described in claim 1 or 2, in which the storage means is a box-shaped case plate, and is provided with a case plate that covers the part of the winding shaft for moving the opening and closing body on the opening direction side of the opening and closing body, the part opposite the main body side, and the part on the closing direction side of the opening and closing body, and a reinforcing member that is provided at the end of the storage means on the main body side and the opening direction side of the opening and closing body, and that reinforces the case plate, and the main body is fixed to the reinforcing member.

[0013] The detection means installation structure described in claim 8 is the detection means installation structure described in claim 1 or 2, wherein the detection means are provided on both sides in the width direction of the opening in the storage means. [Effects of the Invention]

Therefore, it is possible to avoid harm (for example, damage to the opening / closing body) associated with irregular winding of the opening / closing body, and to improve safety when using the opening / closing device.

[0015] According to the installation structure of the detection means described in claim 2, the detection means is configured so that the longitudinal direction of the detection body is aligned with the opening and closing direction of the opening and closing body. Therefore, compared to when the longitudinal direction of the detection body is inclined toward the opposite side from the main body, false detection by the detection means can be suppressed, and the detection accuracy of the detection means can be more easily ensured.

[0016] According to the installation structure of the detection means described in claim 3, the detection means is configured so that the tip of the detection body is located on the other side of the opening direction or closing direction of the opening / closing body relative to the axis of the winding shaft for moving the opening / closing body open and closed.Therefore, it is possible to detect any irregular winding of the opening / closing body toward the main body earlier than when the tip of the detection body is located on either the opening direction or closing direction of the opening / closing body relative to the axis of the winding shaft, and the accuracy of the detection can be improved.

[0017] According to the installation structure of the detection means described in claim 4, the main body is positioned at the end of the storage means on the opening direction side of the opening / closing body or in a position nearby, and the detection body is provided so that it protrudes from the main body toward the closing direction side of the opening / closing body.This makes it possible to install the detection means relatively easily while avoiding harm to the detection means due to the opening / closing body being wound up toward the main body (for example, the detection means being damaged or broken due to being pressed by the opening / closing body), thereby improving the ease of installation of the detection means.

[0018] According to the detection means installation structure of claim 5, the main body is fixed to the case fastening material, so that the main body can be firmly fixed and the stability of the installation of the detection means can be improved.

[0019] According to the installation structure of the detection means described in claim 6, the storage means is a notch provided in the case plate, and is equipped with a notch that allows the wiring connected to the detection means to be inserted through the notch, so that the wiring work to be connected to the detection means can be performed easily and quickly, and the workability of the work can be improved.

[0020] According to the detection means installation structure of claim 7, the main body is fixed to the reinforcing member, so that the main body can be firmly fixed, and the stability of the installation of the detection means can be improved.

[0021] According to the installation structure of the detection means described in claim 8, the detection means is provided on both sides of the width of the opening in the storage means, so that any irregularities in the winding of the opening / closing body toward the main body can be detected more accurately than when the detection means is provided on only one side of the width of the opening in the storage means, thereby further improving the accuracy of the detection.

[0026] Here, the specific type of "building" is arbitrary, but the concept includes, for example, factory facilities, apartment complexes such as apartments and condominiums, detached houses, office buildings, commercial facilities, and public facilities.

[0027] Furthermore, an "opening in a building" is an opening formed in a part of the building's framework (for example, a wall, floor, ceiling, etc.) for installing an entrance or window.

[0028] Furthermore, an "opening and closing device" equipped with an opening and closing body is a device that is attached to an opening in a building for the purpose of crime prevention and fire prevention.

[0029] The concept of this opening and closing device includes all types of shutter devices that can electrically drive heavy shutters, for example.

[0030] Furthermore, the "open / closed state of the opening / closing body" is a concept that includes, for example, a "fully closed state," a "fully open state," and a "half-open state."

[0031] Of these, the "fully closed state" refers to a state in which the opening is fully closed by the opening / closing body, and in the embodiment, the position of the opening / closing body in the fully closed state is referred to as the "fully closed position."

[0032] Furthermore, the "fully open state" refers to a state in which the opening is fully opened by the opening / closing body, and in the embodiment, the position of the opening / closing body in the fully open state is referred to as the "fully open position."

[0034] Furthermore, "disturbance in winding of the opening / closing body" means that the opening / closing body is excessively deformed so as to bulge radially outward from the winding shaft described below when winding and / or unwinding the opening / closing body.

[0035] Furthermore, "abnormal winding" including "irregular winding of the opening / closing body" refers to an abnormality that occurs when the opening / closing body is wound up or / and unwound inside the storage means.

[0036] This winding abnormality includes, for example, irregular winding of the opening / closing body caused by the opening / closing body getting caught on the guide rail described below while being moved to the closing position, irregular winding of the opening / closing body caused by the opening / closing body overrunning in the closing direction (excessive winding of the opening / closing body), and / or the entire opening / closing body being stored in the storage means due to the opening / closing body overrunning in the opening direction (excessive winding of the opening / closing body).

[0037] Furthermore, "inside the storage means" means the inside of a space (hereinafter referred to as "storage space") surrounded by at least two or more components that constitute the storage means (for example, the drive side bearing plate described below, the driven side bearing plate described below, the case plate described below, etc.).

This opening / closing device 50 is configured, for example, by a known opening / closing device, and as shown in Figures 3 and 4, is provided outside the storage section 10 at a position rearward of the storage section 10 and in the vicinity of the drive-side bearing plate 11, and is fixed by a fixture or the like to a connecting plate 51 (for example, a rectangular steel plate) connected to the drive-side bearing plate 11.

[0082] (Configuration-Control System) Returning to FIG. 1, the configuration of the control system 60 will now be described.

[0083] The control system 60 is for controlling the opening and closing device 1, and as shown in Figures 1 to 4 and 8, it includes an operating device 70, a limit position detection unit 80, an obstacle detection unit 90, a left-side first detection device 100, a right-side first detection device 110, a second detection device 120, a power cut-off unit 130, and a control device 140.

[0084] (Configuration - Control System - Operation Device) Returning to Fig. 1, the operating device 70 is an operating means for performing the opening and closing operation of the opening / closing body 30. As shown in Fig. 1, the operating device 70 is attached to the outer surface and the inner surface of the body 2 in the vicinity of the opening 3.

[0085] The operating device 70 is configured using, for example, a known operating device for a shutter device (one example is a wired operating device), etc. Specifically, the operating device 70 includes an open button that commands an open operation to electrically move the opening / closing body 30 to the open position, a close button that commands a close operation to electrically move the opening / closing body 30 to the closed position, and a stop button that commands a stop operation to stop the electrically moved closing or opening position (all of which are not shown).

[0086] Furthermore, the specific operation of the operating device 70 is arbitrary, but in the embodiment, when the open button, close button, or stop button is pressed by the user, an operation signal (i.e., open signal, close signal, stop signal) indicating the opening / closing operation corresponding to the pressed button is output to the opening / closing machine 50 via the control device 140, so that the opening / closing body 30 can be electrically moved open or closed by the opening / closing machine 50, or the opening / closing movement of the opening / closing body 30 can be electrically stopped.

[0087] In the embodiment, the operation device 70 is described as communicating with the control device 140 via a wired connection, but this is not limiting, and for example, the operation device 70 may communicate wirelessly with the control device 140. Furthermore, both the wired and wireless operation devices 70 may be provided.

[0088] (Configuration - Control System - Limit Position Detection Unit) The limit position detection unit 80 is a limit position detection means that detects whether the end (specifically, the lower end) of the opening / closing body 30 on the closing direction side is located at a limit position (specifically, an upper limit position (for example, a position flush with the ceiling 5) or a lower limit position (for example, a position abutting the floor)). The limit position detection unit 80 is configured using, for example, known limit position detection means (for example, a combination of an upper limit switch that detects the upper limit position based on the rotation speed of the output shaft of the opening / closing device 50 and a lower limit switch that detects the lower limit position based on the rotation speed of the output shaft of the opening / closing device 50), and is provided outside the storage unit 10 in a position near the opening / closing device 50.

[0089] The specific detection operation of the limit position detection unit 80 is arbitrary, but for example, it operates as follows.

[0090] In other words, when the rotation speed of the output shaft of the opening / closing device 50 reaches the required rotation speed required for the closing direction end of the opening / closing body 30 to reach the upper limit position from the lower end of the opening 3, a signal indicating this (hereinafter referred to as the "upper limit detection signal") is output, and when the rotation speed of the output shaft of the opening / closing device 40 does not reach the required rotation speed, the upper limit detection signal is not output.

[0091] Furthermore, when the rotation speed of the output shaft of the opening / closing device 50 reaches the required rotation speed required for the closing direction end of the opening / closing body 30 to reach the lower limit position from the upper end of the opening 3, a signal indicating this (hereinafter referred to as a "lower limit detection signal") is output. On the other hand, when the rotation speed of the output shaft of the opening / closing device 40 does not reach the required rotation speed, the lower limit detection signal is not output.

[0092] (Configuration - Control System - Obstacle Detection Section) The obstacle detection unit 90 is an obstacle detection means that detects obstacles (for example, people, animals, objects, etc.) that may hinder the closing movement of the opening / closing body 30. This obstacle detection unit is configured using, for example, a known wired (or wireless) seat panel switch, etc., and is attached to the seat panel 33.

[0093] Furthermore, the specific detection operation of the obstacle detection unit 90 is arbitrary, but for example, if the end of the opening-closing body 30 on the closing direction side comes into contact with an obstacle and is lifted upward relative to the opening-closing body 30 during the closing movement of the opening-closing body 30, the obstacle detection unit 90 detects this lifted displacement and outputs a signal (hereinafter referred to as an "obstacle detection signal") containing information indicating that an obstacle has been detected. On the other hand, if the end of the opening-closing body 30 on the closing direction side does not come into contact with an obstacle and is not lifted upward relative to the opening-closing body 30 during the closing movement of the opening-closing body 30, the obstacle detection signal is not output.

[0094] (Configuration - Control System - Detector - Left First Detector) The left-side first detection device 100 is a detection means that detects a winding abnormality (specifically, irregular winding of the opening / closing body 30 toward the main body 2 side (the front side of Figure 7) shown in Figure 7) when such abnormality occurs inside the storage section 10.

[0095] As shown in Figures 3 and 4, this left-side first detection device 100 is provided inside the storage section 10 and is configured using, for example, a known detection sensor (for example, an emergency switch), and specifically includes a first detection body 101 and a first main body section 102.

[0096] (Configuration - Control system - Detector - Left side first detector - First detector) The first detection body 101 is a part of the basic structure of the left-side first detection device 100, and is a detection body that comes into contact with the opening / closing body 30 when the opening / closing body 30 shown in Fig. 7 becomes miswound. This first detection body 101 is configured using, for example, a probe for a known detection sensor, and specifically, is configured as a long probe.

[0097] (Configuration - Control system - Detector - Left side first detector - First main body) Returning to Fig. 3, the first main body 102 is another part of the basic structure of the left-side first detection device 100, and is a main body that outputs a detection signal (hereinafter referred to as the "first detection signal") indicating that a winding disorder (winding abnormality) has occurred in the opening-closing body 30 shown in Fig. 7 when the first detection body 101 comes into contact with the opening-closing body 30. This first main body 102 is configured using, for example, a sensor body for a known detection sensor (a microswitch is one example), and is attached to either end of the first detection body 101 in the longitudinal direction; specifically, as shown in Fig. 3, it is connected to the upper end of the first detection body 101 by a fixture or the like.

[0098] The configuration of the left-side first detector 100 will be described in detail later.

[0099] (Configuration - Control System - Detector - Right Side 1st Detector) The right-side first detection device 110 is a detection means that detects a winding abnormality (specifically, irregular winding of the opening / closing body 30 toward the main body 2 side (the front side of Figure 7) shown in Figure 7) when such abnormality occurs inside the storage section 10.

[0100] As shown in Figure 4, this right-side first detection device 110 is provided inside the storage section 10 and is configured identically to the left-side first detection device 100, and specifically includes a first detection body 101 and a first main body section 102.

[0101] The configuration of the right-side first detector 110 will be described in detail later.

[0102] (Configuration - Control System - Detector - Second Detector) Returning to Figure 3, the second detection device 120 is a detection means that detects any abnormal winding inside the storage section 10 (for example, irregular winding of the opening / closing body 30 toward the side opposite the main body 2 (rear side in Figure 3), and / or overrunning of the opening / closing body 30 in the opening direction (upward in Figure 3) causing the entire opening / closing body 30 to be stored within the storage section 10).

[0103] As shown in Figures 3 and 4, this second detection device 120 is provided inside the storage section 10 and is configured using, for example, a known detection sensor (for example, an emergency switch), and specifically includes an upper second detection body 121, a lower second detection body 122, and a second main body section 123.

[0104] (Configuration - Control system - Detector - Second detector - Upper second detector) Returning to Fig. 3, the upper second detection body 121 is part of the basic structure of the second detection device 120, and comes into contact with the opening / closing body 30 when the above-mentioned winding abnormality occurs (for example, the opening / closing body 30 is wound irregularly toward the side opposite to the main body 2 (the rear side in Fig. 3)). The upper second detection body 121 is configured using, for example, a probe for a known detection sensor, and specifically, as shown in Fig. 3, is configured as a long probe in an inverted L shape, and is provided at the upper end of the second main body part 123.

[0105] (Configuration - Control system - Detector - Second detector - Lower second detector) The lower second detection body 122 is part of the basic structure of the second detection device 120, and comes into contact with the opening / closing body 30 (specifically, the seat plate 33) when the above-mentioned winding abnormality occurs (for example, the opening / closing body 30 overruns in the opening direction (upward in FIG. 3) and the entire opening / closing body 30 is stored in the storage section 10, etc.). This lower second detection body 122 is configured using, for example, a probe for a known detection sensor, and specifically, as shown in FIG. 3, is configured as a substantially Z-shaped probe, and is provided on the lower side of the second main body section 123.

[0106] (Configuration - Control system - Detector - Second detector - Second main body) The second main body 123 is another part of the basic structure of the second detection device 120, and outputs a detection signal (hereinafter referred to as a "second detection signal") indicating that the above-mentioned winding abnormality has occurred when either the upper second detection body 121 or the lower second detection body 122 comes into contact with the opening / closing body 30. This second main body 123 is configured using, for example, a sensor body for a known detection sensor (a microswitch is one example), and is provided near the lower end of the storage section 10 as shown in Fig. 3, and is connected to each of the upper second detection body 121 and the lower second detection body 122 by a fixture or the like.

[0107] (Configuration - Control system - Detection device - Second detection device - Other configurations) The method of installing the second detection device 120 is arbitrary, but in the embodiment, if the opening / closing body 30 becomes irregularly wound toward the opposite side of the main body 2 (the rear side in Figure 3), only the upper second detection body 121 is positioned to come into contact with the opening / closing body 30, and if the opening / closing body 30 overruns in the opening direction and the entire opening / closing body 30 is stored within the storage section 10, only the lower second detection body 122 is positioned to come into contact with the opening / closing body 30, so that the second main body section 123 is unlikely to come into contact with the opening / closing body 30 regardless of whether or not there is any abnormality in the winding.

[0108] 3, the upper second detection body 121 is disposed so as to protrude upward from the second main body portion 123. In more detail, the upper second detection body 121 is disposed so that the tip end of the upper second detection body 121 is located directly below the winding shaft 40 and slightly below the maximum winding diameter M of the winding shaft 40.

[0109] In addition, the lower second detection body 122 is arranged so as to protrude downward from the second main body portion 123. In detail, the lower second detection body 122 is arranged so that the tip end of the lower second detection body 122 is located between the front lintel 18a and the rear lintel 18b.

[0110] Further, the second main body portion 123 is placed on the rear lintel 18b and fixed to the rear lintel 18b by a fixture or the like.

[0111] By installing the device in this manner, the above-mentioned winding abnormality can be detected early, and dangers (such as damage to the opening / closing body 30) associated with the above-mentioned winding abnormality can be avoided.

[0112] (Configuration - Control System - Power Cutoff Section) The power cutoff unit 130 is a power cutoff means that cuts off the power supply to the switchgear 1. This power cutoff unit 130 is configured using, for example, a known power cutoff means (a breaker or the like as one example), and as shown in Fig. 3, is provided outside the storage unit 10 in a position near the control device 140, and is connected to the connection plate 51 by a fixture or the like.

[0113] (Configuration - Control System - Control Device) Returning to Fig. 3, the control device 140 is a device that mutually links the various parts of the opening and closing device 1. As shown in Figs. 3 and 4, this control device 140 is provided outside the storage unit 10 in the vicinity of the opening and closing mechanism 50, and as shown in Fig. 8, includes an input unit 141, an output unit 142, a power supply unit 143, a control unit 144, and a memory unit 145.

[0114] (Configuration - Control system - Control device - Input section) The input unit 141 is an input means that receives input of various signals (e.g., operation signal, upper limit detection signal, lower limit detection signal, obstacle detection signal, first detection signal, second detection signal, etc.) from the operation device 70, the limit position detection unit 80, the obstacle detection unit 90, the left side first detection device 100, the right side first detection device 110, and the second detection device 120, and is configured using, for example, known input terminals, etc.

[0115] (Configuration - Control system - Control device - Output section) The output unit 142 is an output means for outputting various signals to the opening / closing device 50 and the like, and is configured using, for example, known output terminals and the like.

[0116] (Configuration - Control system - Control device - Power supply unit) The power supply unit 143 is a power supply means that supplies power supplied from a commercial power source or a battery (e.g., a battery, etc.) not shown to each part of the control device 140, and also supplies power to the operating device 70, the limit position detection unit 80, the obstacle detection unit 90, the left side first detection device 100, the right side first detection device 110, and the second detection device 120.

[0117] (Configuration - Control system - Control device - Control unit) The control unit 144 is a control means that controls each unit of the control device 140. Specifically, the control unit 144 is a computer that includes a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing the programs and various data.

[0118] As shown in FIG. 8, the control section 144 conceptually includes an opening / closing control section 144a.

[0119] The opening / closing control unit 144a is an opening / closing control means that controls the opening / closing movement of the opening / closing body 30 based on an operation signal input from the operating device 70.

[0120] The processing executed by the control unit 144 will be described in detail later.

[0121] (Configuration - Control system - Control device - Storage unit) The storage unit 145 is a storage means for storing programs and various data required for the operation of the control device 140, and is configured using a rewritable recording medium, and may be a non-volatile recording medium such as a flash memory.

[0122] (Configuration - Installation structure of left side first detection device, etc.) Returning to FIG. 3, the installation structure of the left-side first detector 100 and the right-side first detector 110 will now be described.

[0123] The opening and closing device 1 has an installation structure for installing the left-side first detector 100 and the right-side first detector 110. The features of this installation structure are as follows in this embodiment.

[0124] (Configuration - Installation structure of first left-side detection device, etc. - First feature) First, regarding the first feature of the installation structure of the left-side first detection device 100 and the right-side first detection device 110, the first main body part 102 of the left-side first detection device 100 (or the right-side first detection device 110) is located in the vicinity of the main body 2 and is arranged at or near one end of either the opening direction side (upper side in Figure 3) or the closing direction side (lower side in Figure 3) of the opening / closing body 30 in the storage section 10, and the left-side first detection device 100 and the right-side first detection device 110 are arranged so that the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) protrudes from the first main body part 102 toward the other of the opening direction side (upper side in Figure 3) or the closing direction side (lower side in Figure 3) of the opening / closing body 30.

[0125] Specifically, as shown in Figures 3 and 4, the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned near the front end and near the upper end of the storage section 10 (more specifically, near the front end of the case plate 15).

[0126] In detail, the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned above the winding shaft 40 and is positioned closer to the main body 2 (front side in Figure 3) than the maximum winding diameter M of the winding shaft 40 and the shutter core SC (the center of the guide rail 20 in the fore-and-aft direction).

[0127] Furthermore, the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is disposed so as to protrude downward from the first main body portion 102.

[0128] Due to this first feature, as shown in Fig. 7, it is possible to detect irregular winding of the opening / closing body 30 toward the body 2 side (the rear side in Fig. 7) at an early stage, compared to the conventional technology (technology in which the overrun detection device is installed inside the storage section so that the detection lever of the overrun detection device is located on the opposite side to the body side than the shutter curtain). Therefore, it is possible to avoid the occurrence of harm (for example, damage to the opening / closing body 30) due to irregular winding of the opening / closing body 30, and it is possible to improve the safety when using the opening / closing device 1.

[0129] In addition, the left side first detection device 100 (or the right side first detection device 110) can be installed relatively easily while avoiding harm to the left side first detection device 100 (or the right side first detection device 110) due to the opening / closing body 30 becoming tangled (for example, the left side first detection device 100 (or the right side first detection device 110) being damaged or broken due to being pressed by the opening / closing body 30), thereby improving the ease of installation of the left side first detection device 100 (or the right side first detection device 110).

[0130] However, this is not limited to the above, and for example, the first main body part 102 of the left-side first detection device 100 (or the right-side first detection device 110) may be positioned near the front end and near the lower end of the storage section 10 (for example, near the front lintel 18a), and the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) may be positioned so as to protrude upward from the first main body part 102.

[0131] (Configuration - Installation structure of the first left-side detection device, etc. - Second feature) Returning to Figure 3, the second feature of the installation structure of the left-side first detection device 100 and the right-side first detection device 110 is that the left-side first detection device 100 and the right-side first detection device 110 are configured so that the longitudinal direction of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is aligned with the opening / closing direction of the opening / closing body 30 (the up-and-down direction in Figure 3).

[0132] Specifically, as shown in FIGS. 3 and 4, the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is formed in a straight line as a whole.

[0133] The left first detector 100 and the right first detector 110 are arranged so that the first detector 101 of the left first detector 100 (or the right first detector 110) is aligned in the vertical direction.

[0134] Due to this second feature, false detection by the left-side first detection device 100 (or the right-side first detection device 110) can be suppressed compared to when the longitudinal direction of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is inclined toward the opposite side from the main body 2 (the rear side in Figure 3), making it easier to ensure the detection accuracy of the left-side first detection device 100 (or the right-side first detection device 110).

[0135] However, the present invention is not limited to this, and for example, the first detection object 101 of the left first detection device 100 (or the right first detection device 110) may be formed in a curved shape.

[0136] Alternatively, the left first detector 100 and the right first detector 110 may be arranged so that the first detector 101 of the left first detector 100 (or the right first detector 110) is not aligned in the vertical direction.

[0137] As an example, the left-side first detection device 100 and the right-side first detection device 110 may be arranged so that the longitudinal direction of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is inclined toward the main body 2 (specifically, the front side) or toward the opposite side from the main body 2 (specifically, the rear side).

[0138] (Configuration - Installation structure of the first left-side detection device, etc. - Third feature) Returning to Figure 3, next, regarding the third feature of the installation structure of the left-side first detection device 100 and the right-side first detection device 110, the left-side first detection device 100 and the right-side first detection device 110 are configured so that the tip of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned on the other side of either the opening direction side (upper side in Figure 3) or the closing direction side (lower side in Figure 3) of the opening / closing body 30 relative to the axis C of the winding shaft 40.

[0139] Specifically, as shown in Figures 3 and 4, when the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned at the end portion of the storage section 10 on the opening side of the opening / closing body 30 (the upper end portion in Figure 4) or a position nearby, the longitudinal length of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is set to a length such that the tip portion of the first detection body 101 is positioned below the axis C of the winding shaft 40.

[0140] In detail, the longitudinal length of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is set to about half (or longer than) the vertical length of the drive side bearing plate 11 of the storage section 10.

[0141] Also, as shown in Figure 3, the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned between the main body 2 and the winding shaft 40 so as to be located closer to the main body 2 (forward in Figure 3) than the maximum winding diameter M of the winding shaft 40 and the shutter core SC.

[0142] Due to this third feature, it is possible to detect any irregular winding of the opening / closing body 30 toward the main body 2 shown in Figure 7 (the front side in Figure 7) earlier than when the tip of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is located on either the opening side or closing side of the opening / closing body 30 (the upper side in Figure 4) relative to the axis C of the winding shaft 40, thereby improving the accuracy of the detection.

[0143] 3, by setting the length of the portion of the first detection body 101 below the axis C of the winding shaft 40 to be relatively long, it is possible to widen the detection range for irregular winding of the opening-closing body 30. Therefore, it becomes easier to detect irregular winding of the opening-closing body 30 at an early stage compared to when, for example, the first main body 102 is located below the storage section 10 and the left-side first detection device 100 (or the right-side first detection device 110) is provided so that the linear first detection body 101 protrudes rearward from the first main body 102.

[0144] However, this is not limited to the above. For example, when the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned at the end (specifically, the upper end) of the opening direction side of the opening / closing body 30 in the storage section 10 or a position nearby, the longitudinal length of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) may be set to a length such that the tip of the first detection body 101 is positioned above the axis C of the winding shaft 40.

[0145] Alternatively, when the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned at the end (specifically, the lower end) of the opening / closing body 30 in the storage section 10 in the closing direction or at a position nearby, the longitudinal length of the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) may be set to a length such that the tip of the first detection body 101 is positioned above (or below) the axis C of the winding shaft 40.

[0146] (Configuration - Installation structure of the first left-side detection device, etc. - Fourth feature) Returning to Figure 4, the fourth feature of the installation structure of the left-side first detection device 100 and the right-side first detection device 110 is that the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is fixed to the upper case fastening material 16 of the storage section 10.

[0147] Specifically, as shown in Figures 4 to 6, the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) is inserted into the insertion hole 150 formed in the second retaining material piece 16b of the upper case retaining material 16, and then fixed by inserting a fixing device (such as a screw) through an attachment plate 151 attached to the upper end of the first main body portion 102 and an attachment hole 152 formed in the second retaining material piece 16b.

[0148] This fourth feature allows the first main body portion 102 of the left-side first detection device 100 (or right-side first detection device 110) to be firmly fixed, thereby increasing the stability of the installation of the left-side first detection device 100 and the right-side first detection device 110.

[0149] However, this is not limited to this, and for example, the first main body portion 102 of the left-side first detection device 100 (or the right-side first detection device 110) may be fixed to something other than the upper case fastening material 16 of the storage section 10 (for example, the drive side bearing plate 11, the driven side bearing plate 13, or the main body 2 of the storage section 10, etc.).

[0150] (Configuration - Installation structure of the first left-side detection device, etc. - 5th feature) Returning to FIG. 4, the fifth feature of the installation structure of the left-side first detector 100 and the right-side first detector 110 is that the storage section 10 further includes a notch 160, as shown in FIGS.

[0151] The cutout 160 is intended to allow insertion of a wiring 4 (for example, an electric cable or the like) connected to the left-side first detection device 100 (or the right-side first detection device 110) via the cutout 160. The cutout 160 is formed in a rectangular shape (or may be formed in a substantially semicircular shape or the like) that allows the wiring 4 to be inserted therethrough, and a plurality of cutouts 160 are provided on the plurality of case plates 15 of the storage section 10 (two are provided in FIG. 4).

[0152] Specifically, as shown in Figures 4 and 5, the notch 160 is formed at the left end of the front end portion of the case plate 15 located on the leftmost side of the multiple case plates 15, and at the right end of the front end portion of the case plate 15 located on the rightmost side.

[0153] In the following, as necessary, of the notches 160, the notch 161 located on the left side and for inserting the wiring 4a (hereinafter referred to as the "first wiring 4a") connected to the left-side first detection device 100 will be referred to as the "left-side notch 161", and the notch 162 located on the right side and for inserting the wiring 4b (hereinafter referred to as the "second wiring 4b") connected to the right-side first detection device 110 will be referred to as the "right-side notch 162".

[0154] Due to this fifth feature, the wiring work of the wiring 4 (specifically, the first wiring 4a and the second wiring 4b) connected to the left-side first detection device 100 (or the right-side first detection device 110) (specifically, the work of connecting the left-side first detection device 100 or the right-side first detection device 110 to the control device 140 using the first wiring 4a and the second wiring 4b) can be performed easily and quickly, thereby improving the workability of the work.

[0155] However, without being limited thereto, for example, the left-side notch 161 (or the right-side notch 162) may be provided in the front end portion of the central case plate 15 among the multiple case plates 15. Alternatively, the left-side notch 161 (or the right-side notch 162) may be provided in a portion other than the front end portion of the leftmost (or rightmost) case plate 15 (for example, a central portion of the case plate 15). Alternatively, the left-side notch 161 (or the right-side notch 162) may be provided in a portion other than the case plate 15 (for example, the driving-side bearing plate 11 or the driven-side bearing plate 13, etc.).

[0156] Furthermore, the storage section 10 may be provided with only one notch 160 through which both the first wiring 4a and the second wiring 4b can be inserted.

[0157] (Configuration - Installation structure of the first left-side detection device, etc. - 6th feature) Returning to Figure 2, the fifth feature of the installation structure of the left-side first detection device 100 and the right-side first detection device 110 is that the left-side first detection device 100 and the right-side first detection device 110 are provided on both sides of the width direction (left-right direction in Figure 2) of the opening 3 in the storage section 10.

[0158] Specifically, as shown in Figures 2 and 4, the left-side first detection device 100 is arranged on the left side of the storage section 10 (the opening / closing mechanism 50 side (driving side)), and the right-side first detection device 110 is arranged on the right side of the storage section 10 (the opposite side to the opening / closing mechanism 50 side (driven side)).

[0159] In detail, the left-side first detection device 100 is arranged near the front end and near the left end of the storage section 10, and the right-side first detection device 110 is arranged near the front end and near the right end of the storage section 10.

[0160] Due to this sixth feature, compared to when the left-side first detection device 100 and / or the right-side first detection device 110 are provided on only one side of the width of the opening 3 in the storage section 10, it is possible to accurately detect any irregularities in the winding of the opening / closing body 30 toward the main body 2 side shown in Figure 7 (the front side of Figure 7), thereby further improving the accuracy of the detection.

[0161] However, the present invention is not limited to this, and for example, the left first detector 100 and the right first detector 110 may be provided on only one side of the opening 3 in the storage section 10 in the width direction.

[0162] With the above-described installation structure, it is possible to improve the safety of the switching device 1 when it is in use, and it is possible to improve the usability of the installation structure.

[0163] (Opening and closing process) Next, the opening and closing process executed by the control unit 144 of the control device 140 of the control system 60 will be described.

[0164] In the following description, steps will be abbreviated as "S" in the description of each process shown in FIG.

[0165] The opening / closing process is a process for controlling the opening / closing movement of the opening / closing body 30.

[0166] The timing for executing this opening / closing process is arbitrary, but in the embodiment, it is described as being started after the power supply of the opening / closing device 1 is turned on.

[0167] (Opening and closing process - premise) Next, the premise of the opening and closing process in this embodiment is as follows.

[0168] That is, the opening and closing state of the opening and closing body 30 will be described as being in a fully closed state.

[0169] In addition, the description will be given on the assumption that the opening and closing device 1 has already executed the processes required for the opening and closing process (for example, the initial process for setting the upper limit position and the lower limit position, etc.).

[0170] The switching device 1 will be described as receiving power from a commercial power source.

[0171] (Opening and closing process - Opening and closing process details) Next, the opening and closing process will be described in detail.

[0172] When the opening / closing process is initiated, as shown in FIG. 9, in SA1, the opening / closing control unit 144a of the control device 140 determines whether or not an input of an operation signal (specifically, an open signal, a close signal, or a stop signal) has been received from the operating device 70 via the input unit 141.

[0173] Then, the opening / closing control unit 144a of the control device 140 waits until it is determined that the input of the operation signal has been accepted (SA1, No), and if it is determined that the input of the operation signal has been accepted (SA1, Yes), it proceeds to SA2.

[0174] In SA2, the opening / closing control section 144a of the control device 140 performs self-holding control based on the operation signal received as input in SA1.

[0175] Here, "self-holding control" means control that moves the opening / closing body 30 to open or close based on the operation signal even if the input of the operation signal from the operating device 70 is accepted and then the acceptance is stopped.

[0176] The control content of this self-holding control is arbitrary, but in this embodiment, the control is carried out as follows.

[0177] That is, when the opening / closing control unit 144a of the control device 140 receives an input of an operation signal (specifically, an open signal, a close signal, or a stop signal) of SA1, it outputs a control signal corresponding to the operation signal to the opening / closing device 50 via the output unit 142, thereby driving the opening / closing device 50 based on the control signal to open or close the opening / closing body 30 (specifically, to open or close), or stops driving the opening / closing device 50 based on the control signal to stop the opening / closing movement of the opening / closing body 30.

[0178] Then, even if the input of the above-mentioned operation signal can no longer be accepted, the opening / closing control unit 144a of the control device 140 continues to output the above-mentioned control signal to the opening / closing device 50 until input of another operation signal is accepted by SA5 or the like, as described below, thereby continuing the opening / closing movement of the opening / closing body 30 or continuing to stop the opening / closing movement of the opening / closing body 30.

[0179] Also, in the embodiment, although not shown in the flowchart of FIG. 9, the following control is also performed while self-holding control is being performed at SA2 (the same applies to the processing at SA4 and the processing at SA7 described below).

[0180] That is, the opening / closing control unit 144a of the control device 140 determines whether the position of the end (specifically, the lower end) of the opening / closing body 30 on the closing direction side has reached either the upper limit position or the lower limit position while self-holding control is being performed.

[0181] The method for determining whether the upper limit position or the lower limit position has been reached is arbitrary, but in the embodiment, during processing of SA2, the determination is made based on whether an upper limit detection signal or a lower limit detection signal has been received from the limit position detection unit 80 via the input unit 141.

[0182] Here, if the input of an upper limit detection signal or a lower limit detection signal is received, it is determined that either the upper limit position or the lower limit position has been reached, and if the input of an upper limit detection signal or a lower limit detection signal is not received, it is determined that neither the upper limit position nor the lower limit position has been reached.

[0183] If the opening / closing control unit 144a of the control device 140 determines that neither the upper limit position nor the lower limit position has been reached, it continues the opening / closing movement of the opening / closing body 30 using self-holding control, and if it determines that either the upper limit position or the lower limit position has been reached, it stops the opening / closing movement of the opening / closing body 30 using self-holding control, and then proceeds to SA1.

[0184] Furthermore, the opening / closing control section 144a of the control device 140 determines whether or not an obstacle is present at the opening 3 while the self-holding control is being performed.

[0185] Furthermore, the method for determining whether or not an obstacle exists is arbitrary, but in this embodiment, during processing of SA2, the determination is made based on whether or not an obstacle detection signal is received from the obstacle detection unit 90 via the input unit 141.

[0186] Here, if an input of an obstacle detection signal is received, it is determined that an obstacle is present, and if an input of an obstacle detection signal is not received, it is determined that an obstacle is not present.

[0187] If the opening / closing control unit 144a of the control device 140 determines that no obstacle is present, it continues the opening / closing movement of the opening / closing body 30 using self-holding control, and if it determines that an obstacle is present, it stops the opening / closing movement of the opening / closing body 30 using self-holding control, and then proceeds to SA1.

[0188] In SA3, the opening / closing control section 144a of the control device 140 determines whether the left first detector 100, the right first detector 110, and / or the second detector 120 has detected a winding abnormality.

[0189] The method for determining whether or not this winding abnormality has been detected is arbitrary, but in the embodiment, the determination is made based on whether or not input of the first detection signal and / or the second detection signal has been received from the left first detection device 100, the right first detection device 110, and / or the second detection device 120.

[0190] Here, if the input of the first detection signal or / and the second detection signal is accepted, it is determined that a winding abnormality has been detected, and if the input of the first detection signal or / and the second detection signal is not accepted, it is determined that a winding abnormality has not been detected.

[0191] Then, when the opening / closing control unit 144a of the control device 140 determines that a winding abnormality has been detected (SA3, Yes), it switches the self-holding control of SA2 to the push-off control described below and proceeds to SA4 (in other words, when a winding abnormality has been detected, the opening / closing control unit 144a of the control device 140 performs the push-off control described below).

[0192] On the other hand, if the opening / closing control unit 144a of the control device 140 determines that no winding abnormality has been detected (SA3, No), it proceeds to SA5 while continuing the self-holding control of SA2 (i.e., the opening / closing control unit 144a of the control device 140 performs self-holding control when no winding abnormality has been detected).

[0193] In the embodiment, in SA2, it is determined whether the position of the end (specifically, the lower end) of the opening / closing body 30 on the closing direction side has reached either the upper limit position or the lower limit position during self-holding control, and if it is determined that it has reached either the upper limit position or the lower limit position, SA3 is processed even though the opening / closing movement of the opening / closing body 30 under self-holding control is stopped, for the reasons described below.

[0194] That is, even if the position of the end of the opening / closing body 30 on the closing direction side reaches the upper limit or the lower limit during the self-holding control in SA2, it may not be determined that the upper limit or the lower limit has been reached due to a predetermined factor, and the opening / closing movement of the opening / closing body 30 may not be stopped, which may result in a winding abnormality. Therefore, from the viewpoint of safety when using the opening / closing device 1, the processing of SA3 is performed so that such a winding abnormality can also be detected.

[0195] In addition, the "predetermined factor" refers to, for example, the limit position detection unit 80 not operating normally, the limit position detection unit 80 malfunctioning, and / or an error in setting the upper or lower limit position in the limit position detection unit 80.

[0196] At SA4, the opening / closing control section 144a of the control device 140 performs push-off control based on the operation signal input received at SA1, and then the process proceeds to SA6.

[0197] Here, "push-off control" means control for moving the opening / closing body 30 to open or close based on an operation signal only while the input of the operation signal from the operating device 70 is being accepted.

[0198] The control content of this push-off control is arbitrary, but in this embodiment, the control is carried out as follows.

[0199] That is, while the input of an operation signal (specifically, an open signal, a close signal) of SA1 is being accepted, the opening / closing control unit 144a of the control device 140 outputs a control signal corresponding to the operation signal to the opening / closing device 50 via the output unit 142, thereby driving the opening / closing device 50 based on the control signal and causing the opening / closing body 30 to open or close (specifically, to open or close).

[0200] When the opening / closing control unit 144a of the control device 140 is no longer able to accept the input of the operation signal, it stops outputting the control signal to the opening / closing device 50, thereby stopping the operation of the opening / closing device 50 and stopping the opening / closing movement of the opening / closing body 30.

[0201] Specifically, when switching from self-holding control of SA2 to push-off control of SA4, if the input of an operation signal for SA1 is accepted, the opening / closing control unit 144a of the control device 140 moves the opening / closing body 30 to open or close based on the operation signal, and if the input of an operation signal for SA1 is not accepted, stops the opening / closing movement of the opening / closing body 30.

[0202] In the embodiment, the detection continues until a non-detection operation (described later) is performed or until a limit control (described later) is executed.

[0203] In SA5, the opening / closing control unit 144a of the control device 140 determines whether or not an input of an operation signal has been received from the operating device 70 via the input unit 141 when self-holding control of SA2 is being performed (specifically, when opening / closing movement of the opening / closing body 30 is being performed by self-holding control based on an operation signal such as SA1 or SA5).

[0204] Then, when it is determined that the input of the operation signal has been accepted (SA5, Yes), the opening / closing control section 144a of the control device 140 proceeds to SA2, and performs self-holding control in SA2 based on the operation signal of SA5.

[0205] On the other hand, when it is determined that the input of the operation signal has not been accepted (SA5, No), the opening / closing control section 144a of the control device 140 proceeds to SA3 while continuing the self-holding control of SA2.

[0206] By performing the processes SA1 to SA5 in this manner, self-holding control can be performed when no winding abnormality is detected by the left-side first detector 100, the right-side first detector 110, and the second detector 120, and push-off control can be performed when a winding abnormality is detected by the left-side first detector 100, the right-side first detector 110, and / or the second detector 120. Therefore, compared to the conventional technology (technology in which the drive stop device stops the drive of the motor), when the winding abnormality is detected, the opening / closing body 30 can be opened and closed while ensuring safety without having to perform a reset operation to reset the motor before the winding abnormality is detected, and the usability of the control system 60 can be improved.

[0207] In SA6, the opening / closing control unit 144a of the control device 140 determines whether or not input of an operation signal has been received from the operating device 70 via the input unit 141 when push-off control of SA4 is being performed (for example, when the opening / closing body 30 is being moved open or closed by push-off control based on the operation signal of SA1 when processing SA6, or when the opening / closing body 30 is not being moved open or closed by push-off control based on the operation signal of SA1 when processing SA6, but push-off control is continuing).

[0208] Then, the opening / closing control unit 144a of the control device 140 waits until it is determined that the input of the operation signal has been accepted (SA6, No), and if it is determined that the input of the operation signal has been accepted (SA6, Yes), it proceeds to SA7.

[0209] In SA7, the opening / closing control unit 144a of the control device 140 performs the push-off control based on the operation signal input received in SA6, similar to the process in SA4.

[0210] In SA8, when the push-off control of SA7 is being performed (specifically, when the opening / closing body 30 is being moved open or closed by push-off control based on the operation signal of SA6 when SA8 is being processed, or when the opening / closing body 30 is not being moved open or closed by push-off control based on the operation signal of SA6 when SA8 is being processed, but the push-off control is continuing), the opening / closing control unit 144a of the control device 140 determines whether the opening / closing operation indicated by the operation signal accepted as input in SA6 is a non-detection operation.

[0211] Here, "non-detection operation" means an opening / closing operation indicated by an operation signal in which winding abnormalities are not detected by the left first detection device 100, the right first detection device 110, and the second detection device 120.

[0212] Details of this non-detection operation include, for example, the following operations.

[0213] In other words, if the winding abnormality is a winding irregularity of the opening / closing body 30 caused by the opening / closing body 30 getting caught on the guide rail 20 described below while moving the opening / closing body 30 in the closing direction, or a winding irregularity of the opening / closing body 30 caused by the opening / closing body 30 overrunning in the closing direction, then the opening operation applies.

[0214] Also, if the abnormal winding is such that the entire opening / closing body 30 is stored in the storage section 10 due to overrunning of the opening / closing body 30 in the opening direction, this corresponds to a closing operation.

[0215] Furthermore, the method for determining whether or not the operation is an undetected operation is arbitrary, but in this embodiment, the determination is made as follows.

[0216] That is, first, it is determined whether the state in which the opening / closing machine 50 is being driven by the push-off control by SA7 and the state in which a winding abnormality is detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120 continues for a predetermined time.

[0217] Specifically, it is determined whether the state in which the input of a signal indicating that the opening / closing device 50 is operating (hereinafter referred to as the "drive signal") is received from the opening / closing device 50 via the input unit 141 and the state in which the input of the first detection signal and / or the second detection signal is received via the input unit 141 continue for a predetermined period of time (e.g., 300 msec, etc.).

[0218] Here, if it is determined that the operation has continued for the predetermined time, it is determined that the operation is not the undetected operation.

[0219] On the other hand, if it is determined that the state in which a winding abnormality is detected by at least the left first detection device 100, the right first detection device 110, and / or the second detection device 120 has not continued for the above-mentioned predetermined time, it is determined that the above-mentioned non-detection operation has occurred.

[0220] Specifically, if the state in which the input of the drive signal is being accepted via the input unit 141 continues, but the state in which the input of the first detection signal and / or the second detection signal is being accepted via the input unit 141 does not continue, and it is determined that this has not continued for the specified time, then it is determined that this is the non-detection operation.

[0221] However, this is not limited to this, and it may be determined that the non-detection operation has occurred, for example, when it is determined that the state in which the input of the drive signal is accepted via the input unit 141 and the state in which the input of the first detection signal and / or the second detection signal is accepted via the input unit 141 have not continued for the specified period of time.

[0222] Then, when it is determined that the operation is the undetected operation (SA8, Yes), the opening / closing control section 144a of the control device 140 switches from the push-off control to the self-holding control, and proceeds to SA2.

[0223] In this case, in SA2, the opening / closing control section 144a of the control device 140 performs self-holding control based on the operation signal whose input is accepted in SA6.

[0224] In the embodiment, if it is determined in SA8 that the state in which a winding abnormality is detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120 continues, but the state in which the opening / closing machine 50 is operating does not continue, and therefore the state has not continued for the above-mentioned specified time, the opening / closing control unit 144a of the control device 140 proceeds to SA6 and repeats the processing from SA6 to SA8 (i.e., continues the push-off control) until it is determined in SA8 that the above-mentioned non-detection operation has occurred or that the above-mentioned non-detection operation has not occurred.

[0225] That is, in the process of transitioning from SA8 to SA2, when the open / close control unit 144a of the control device 140 determines that the open / close operation indicated by the operation signal received as input from the operating device 70 is a non-detection operation while the push-off control is being performed, the open / close control unit 144a controls the open / close movement of the open / close body 30 based on the operation signal. Also, when the control of the open / close movement of the open / close body 30 based on the operation signal continues and the left first detector 100, the right first detector 110, and the second detector 120 no longer detect a winding abnormality, the open / close control unit 144a switches from the push-off control to the self-holding control.

[0226] If such processing determines that the operation is an undetected operation, the push-off control can be continued based on the operation signal indicating the undetected operation, and the undetected operation can return the state of the opening / closing body 30 to the state before the winding abnormality occurred.

[0227] Furthermore, if the winding abnormality is no longer detected due to the continuation of the push-off control, the push-off control can be switched to the self-holding control, and the return to the self-holding control can be easily performed.

[0228] Furthermore, based on the state of the opening / closing device 50 and the detection state of the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, it is possible to switch from push-off control to self-holding control, and the opening / closing movement of the opening / closing body 30 can be controlled according to the situation.

[0229] On the other hand, if it is determined that the undetected operation is not the one described above (SA8, No), the opening / closing control section 144a of the control device 140 switches from the push-off control to the limit control described below, and proceeds to SA9.

[0230] That is, in the process of transitioning from SA8 to SA9, when the push-off control is being performed, the opening / closing control unit 144a of the control device 140 switches from the push-off control to the limit control described below if it determines that the opening / closing operation indicated by the operation signal received as input from the operating device 70 is not a non-detection operation.

[0231] If such processing determines that the operation is not an undetected operation, the limiting control described below can be performed, and it is possible to prevent the opening / closing body 30 from being opened or closed erroneously after the determination.

[0232] In addition, based on the state of the opening / closing device 50 and the detection state of the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, it is possible to switch from push-through control to the limit control described below, and to control the opening / closing movement of the opening / closing body 30 according to the situation.

[0233] In SA9, the switching control section 144a of the control device 140 performs limit control.

[0234] Here, the term "limiting control" refers to control that limits the opening and closing movement of the opening / closing body 30 based on an operation signal.

[0235] This limitation control is a concept that includes, for example, power limitation control and / or reception limitation control, but in the embodiment, it will be described as power limitation control.

[0236] Of these, the "power limiting control" refers to control in which the power cutoff unit 130 cuts off the power supply to the opening / closing device 1, thereby limiting the opening / closing movement of the opening / closing body 30 based on the operation signal.

[0237] The control content of this power limit control is arbitrary, but in the embodiment, the opening / closing control unit 144a of the control device 140 outputs a control signal indicating that the opening / closing movement of the opening / closing body 30 is to be restricted to the power cut-off unit 130 via the output unit 142, and based on the control signal, the power cut-off unit 130 cuts off the power supply from the commercial power source to the opening / closing device 1, thereby restricting the opening / closing movement of the opening / closing body 30.

[0238] In addition, "reception restriction control" means control that restricts the opening and closing movement of the opening / closing body 30 based on the operation signal by not accepting the input of an operation signal from the operating device 70 (or by accepting the input but ignoring the operation signal).

[0239] The control content of this acceptance restriction control is arbitrary, but for example, the opening / closing control unit 144a of the control device 140 may output a control signal to the input unit 141 indicating that it will not accept input of an operation signal from the operating device 70 (or that even if the input is accepted, the operation signal will be ignored), thereby restricting the opening / closing movement of the opening / closing body 30 by not accepting input of an operation signal by the input unit 141 based on the control signal (or by accepting the input but ignoring the operation signal).

[0240] In the embodiment, the limit control (specifically, the power limit control) is assumed to be continuously performed until the return timing described later arrives.

[0241] By performing such processing at SA9, it is possible to perform power limit control as limit control, and it is possible to prevent the opening / closing body 30 from being erroneously opened or closed due to an erroneous operation of the operating device 70 or a malfunction of the opening / closing device 1.

[0242] In SA10, the switching control section 144a of the control device 140 determines whether or not the return timing has arrived.

[0243] Here, "return timing" means the timing at which the state returns to the state before the winding abnormality detected by SA3 occurred.

[0244] In the embodiment, this return timing is described as the timing when the input of the return operation is received via the operating device 70 and / or the power cut-off unit 130 after repair work to repair the opening / closing body 30 and operation confirmation work to check the operation of the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120 have been performed.

[0245] Furthermore, the method for determining whether the timing for restoration has arrived is arbitrary, but in the embodiment, the determination is made based on whether input of the restoration operation has been accepted via the operating device 70 and / or the power cut-off unit 130.

[0246] Here, if the input of the return operation is accepted, it is determined that the return timing has arrived, and if the input of the return operation is not accepted, it is determined that the return timing has not arrived.

[0247] Then, the opening / closing control unit 144a of the control device 140 waits until it is determined that the return timing has arrived (SA10, No), and if it is determined that the return timing has arrived (SA10, Yes), it proceeds to SA11.

[0248] At SA11, the switching control section 144a of the control device 140 stops the execution of the limit control, and then proceeds to SA1, and thereafter similarly repeats the processes from SA1 to SA11.

[0249] The method for stopping the execution of this restriction control is arbitrary, but in the embodiment, a control signal indicating that the restriction on the opening and closing movement of the opening and closing body 30 is lifted is output to the power cut-off unit 130 via the output unit 142, and the power cut-off unit 130 resumes the supply of power from the commercial power source to the opening and closing device 1 based on the control signal, thereby stopping the execution of the restriction control (i.e., allowing the opening and closing movement of the opening and closing body 30 based on the operation signal).

[0250] By the opening and closing process as described above, the opening and closing movement of the opening and closing body 30 can be controlled depending on the situation while ensuring safety, and the usability of the opening and closing device 1 can be improved.

[0251] (Effects of the embodiment) Thus, according to the embodiment, the first main body 102 is located near the frame 2 and is disposed at or near one end of the storage section 10 on either the opening or closing side of the opening / closing body 30, and the left-side first detector 100 (or the right-side first detector 110) is provided so that the first detector 101 protrudes from the first main body 102 toward either the opening or closing side of the opening / closing body 30. This makes it possible to detect irregular winding of the opening / closing body 30 toward the frame 2 earlier than in the prior art (a technique in which an overrun detector is installed inside the storage section so that the detection lever of the overrun detector is located on the opposite side of the shutter curtain from the frame 2). This makes it possible to avoid harm (for example, damage to the opening / closing body 30) associated with irregular winding of the opening / closing body 30, and improves safety when using the opening / closing device 1.

[0252] Furthermore, since the left-side first detection device 100 (or the right-side first detection device 110) is configured so that the longitudinal direction of the first detection body 101 is aligned with the opening and closing direction of the opening and closing body 30, false detection by the left-side first detection device 100 (or the right-side first detection device 110) can be suppressed compared to when the longitudinal direction of the first detection body 101 is inclined toward the opposite side from the main body 2, making it easier to ensure the detection accuracy of the left-side first detection device 100 (or the right-side first detection device 110).

[0253] Furthermore, the left-side first detection device 100 (or the right-side first detection device 110) is configured so that the tip of the first detection body 101 is located on the other side of the opening direction or closing direction of the opening-closing body 30 relative to the axis C of the winding shaft 40 for moving the opening-closing body 30 open and closed.Therefore, any irregular winding of the opening-closing body 30 toward the main body 2 can be detected earlier than when the tip of the first detection body 101 is located on either the opening direction or closing direction of the opening-closing body 30 relative to the axis C of the winding shaft 40, and the accuracy of the detection can be improved.

[0254] Furthermore, the first main body 102 is positioned at the end of the storage section 10 on the opening direction side of the opening / closing body 30 or at a position nearby, and the left-side first detection device 100 (or the right-side first detection device 110) is arranged so that the first detection body 101 protrudes from the first main body 102 toward the closing direction side of the opening / closing body 30.This makes it possible to install the left-side first detection device 100 (or the right-side first detection device 110) relatively easily while avoiding harm to the left-side first detection device 100 (or the right-side first detection device 110) due to the opening / closing body 30 being wound up toward the main body 2 (for example, damage or malfunction of the left-side first detection device 100 (or the right-side first detection device 110) due to being pressed by the opening / closing body 30), thereby improving the ease of installation of the left-side first detection device 100 (or the right-side first detection device 110).

[0255] Furthermore, since the first main body portion 102 is fixed to the upper case fastening material 16, the first main body portion 102 can be firmly fixed, thereby increasing the stability of the installation of the left-side first detection device 100 (or the right-side first detection device 110).

[0256] Furthermore, the storage section 10 is provided with a notch 160 in the case plate 15, which allows the wiring 4 (specifically, the first wiring 4a and the second wiring 4b) connected to the left-side first detection device 100 (or the right-side first detection device 110) to be inserted through the notch 160. This makes it possible to easily and quickly perform the wiring work of the wiring 4 connected to the left-side first detection device 100 (or the right-side first detection device 110), thereby improving the workability of the work.

[0257] Furthermore, since the left side first detection device 100 (or the right side first detection device 110) is provided on both sides of the width of the opening 3 in the storage section 10, any irregular winding of the opening / closing body 30 toward the main body 2 can be detected more accurately than when the left side first detection device 100 (or the right side first detection device 110) is provided on only one side of the width of the opening 3 in the storage section 10, thereby further improving the accuracy of the detection.

[0258] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims. Such modifications will be described below.

[0259] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

[0260] (Regarding decentralization and integration) Furthermore, the electrical components described above are functional concepts and do not necessarily have to be physically configured as shown in the drawings. In other words, the specific form of distribution or integration of each part is not limited to that shown in the drawings, and all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. Furthermore, the term "device" in this application is not limited to a single device, but includes a device configured from multiple devices.

[0261] For example, the control device 140 according to the embodiment may be configured as a plurality of devices that are configured to be able to communicate with each other, with a control unit 144 provided in some of the devices and a memory unit 145 provided in another of the devices.

[0262] (shape, numbers, structure, time series) The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention in terms of shape, numerical value, or the structure or chronological relationship of multiple components.

[0263] (About the storage area) In the above embodiment, the storage section 10 is described as including the curved case plate 15, the upper case stopper 16, and the lower case stopper 17, but the present invention is not limited to this.

[0264] For example, the case plate 15 may be omitted.

[0265] Alternatively, as shown in FIG. 10, the storage section 10 may be capable of storing the opening / closing device 50 and the control device 140, and may be provided with a box-shaped case plate 170 and a reinforcing member 180 instead of the curved case plate 15, the upper case stopper 16, and the lower case stopper 17.

[0266] Of these, the case plate 170 covers the portion of the winding shaft 40 on the opening direction side of the opening / closing body 30 (the upper side portion in FIG. 10), the portion on the opposite side from the main body 2 (the rear side portion in FIG. 10), and the portion on the closing direction side of the opening / closing body 30 (the lower side portion in FIG. 10). As shown in FIG. 10, this case plate 170 is formed of a steel box-shaped body having an upper case piece 171, a lower case piece 172, a left case piece 173, a right case piece 174, and a rear case piece 176, and is provided so as to protrude rearward from the main body 2 and is fixed to the main body 2 by a fixture or the like.

[0267] Further, the reinforcing member 180 is for reinforcing the case plate 170. This reinforcing member 180 is configured using, for example, a known long reinforcing material (one example is an angle bar, etc.), and as shown in Fig. 10, is provided on the housing 10 side (the front side in Fig. 10) and on the end portion in the opening direction of the opening / closing body 30 (the upper end portion in Fig. 10).

[0268] Specifically, reinforcing member 180 is disposed so that the longitudinal direction of reinforcing member 180 is aligned with the left-right direction, and is fixed to upper case piece 171 with a fixture, by welding, or the like.

[0269] In the configuration of the storage section 10 described above, only the left first detector 100 may be provided, as shown in FIG.

[0270] Furthermore, the first main body portion 102 of the left-side first detection device 100 may be installed in any manner, and may be fixed to the reinforcing member 180, for example. In particular, the first main body portion 102 may be fixed to the reinforcing member 180 by a fixture or the like via a mounting plate 181 and a connecting member 182 (for example, a steel angle bar) attached to the upper end of the first main body portion 102.

[0271] By installing the first left-side first detector 100 in this manner, the first main body 102 of the left-side first detector 100 can be firmly fixed, and the installation stability of the left-side first detector 100 can be improved.

[0272] (Regarding control systems) In the above embodiment, the control system 60 is described as being equipped with the left-side first detection device 100 and the right-side first detection device 110, but this is not limited thereto, and for example, either the left-side first detection device 100 or the right-side first detection device 110 may be omitted.

[0273] In this case, for example, the other of the left-side first detector 100 and the right-side first detector 110 may be provided on only one side of the opening 3 in the storage section 10 in the width direction, or may be provided in the center of the opening 3 in the width direction of the storage section 10. Also, either the left-side cutout 161 or the right-side cutout 162 may be omitted.

[0274] Alternatively, in addition to the left-side first detector 100 and the right-side first detector 110, the control system 60 may further include a first detector (detection means) configured identically to the left-side first detector 100, with at least one or more first detectors provided between the left-side first detector 100 and the right-side first detector 110.

[0275] In this case, for example, a notch 160 corresponding to the first detection device may be further provided in the case plate 15.

[0276] Furthermore, in the above embodiment, the control system 60 is described as being equipped with the second detection device 120 and the power cut-off unit 130, but this is not limited thereto, and for example, the second detection device 120 and / or the power cut-off unit 130 may be omitted.

[0277] When the power cutoff unit 130 is omitted, the restriction control performed at SA9 of the switching process may be an acceptance restriction control.

[0278] (Installation structure of the left-side first detection device and the right-side first detection device) In the above embodiment, it has been explained that the first main body part 102 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned near the front end and near the upper end of the storage section 10, and that the first detection body 101 of the left-side first detection device 100 (or the right-side first detection device 110) is positioned so as to protrude downward from the first main body part 102, but this is not limited to this.

[0279] For example, the first main body part 102 may be positioned near the front end of the storage part 10 and near the lower end (i.e., the end on the closing direction side of the opening / closing body 30), and the first detection body 101 may be positioned so as to protrude from the first main body part 102 upward (i.e., the opening direction side of the opening / closing body 30).

[0280] (About opening and closing process) In the above embodiment, it was explained that the opening / closing control unit 144a performs push-off control when a winding abnormality is detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, but this is not limited to this.

[0281] For example, limit control (for example, power limit control) may be performed instead of push-off control. In this case, for example, when the return timing arrives after limit control has been performed, the opening / closing control unit 144a may switch from limit control to self-holding control.

[0282] Alternatively, the opening / closing control unit 144a may perform push-off control when a winding abnormality is detected by the left-side first detection device 100 and / or the right-side first detection device 110, but may perform limit control when a winding abnormality is detected by the second detection device 120.

[0283] Furthermore, in the above embodiment, it was explained that when push-off control is being performed, the opening / closing control unit 144a switches to limit control if it is determined that the opening / closing operation indicated by the operation signal received as input from the operating device 70 is not a non-detection operation, but this is not limited to this, and for example, push-off control may be continued.

[0284] In this case, for example, the processes from SA9 to SA11 may be omitted, and the push-off control may be continued until it is determined that the opening / closing operation is a non-detection operation.

[0285] In addition, in the above embodiment, the opening / closing control unit 144a determines whether a winding abnormality has been detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, and switches from self-holding control to push-off control based on the determination result, and then determines whether the opening / closing operation indicated by the operation signal received as input from the operation device 70 is a non-detection operation, and switches the push-off control to limit control or self-holding control based on the determination result, but this is not limited to this.

[0286] For example, the opening / closing control unit 144a may determine whether a first winding abnormality has been detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, and switch from self-holding control to push-off control based on the determination result, and then determine whether a second winding abnormality has been detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120, and switch the push-off control to limit control or self-holding control based on the determination result (in other words, the opening / closing control unit 144a may determine whether a winding abnormality has been detected in two stages, and switch control based on these determination results).

[0287] In this case, for example, the left-side first detector 100, the right-side first detector 110, and / or the second detector 120 may be configured using a detection sensor that can detect the amount of deformation due to irregular winding of the opening-closing body 30. Furthermore, the opening-closing control unit 144a may determine whether a first winding abnormality has been detected based on whether a first detection signal and / or a second detection signal indicating that the amount of deformation due to irregular winding of the opening-closing body 30 detected by the left-side first detector 100, the right-side first detector 110, and / or the second detector 120 has reached a first deformation amount has been received. Then, after it is determined that a first winding abnormality has been detected, it may be determined whether a second winding abnormality has been detected based on whether a first detection signal and / or a second detection signal has been received indicating that the amount of deformation due to irregular winding of the opening / closing body 30 detected by the left-side first detection device 100, the right-side first detection device 110, and / or the second detection device 120 has reached a second deformation amount (specifically, a deformation amount greater than the first deformation amount).

[0288] Alternatively, the opening / closing control unit 144a may determine whether a first winding abnormality has been detected based on whether a first detection signal and / or a second detection signal has been received from the left-side first detector 100, the right-side first detector 110, and / or the second detector 120. Then, after a predetermined time has elapsed since it was determined that a first winding abnormality has been detected, the opening / closing control unit 144a may determine whether a second winding abnormality has been detected based on whether a first detection signal and / or a second detection signal has been received from the left-side first detector 100, the right-side first detector 110, and / or the second detector 120.

Therefore, it is possible to avoid harm (for example, damage to the opening / closing body) associated with irregular winding of the opening / closing body, and to improve safety when using the opening / closing device.

[0298] According to the installation structure of the detection means described in Appendix 2, the detection means is configured so that the longitudinal direction of the detection body is aligned with the opening and closing direction of the opening and closing body.

[0299] According to the installation structure of the detection means described in Appendix 3, the detection means is configured so that the tip of the detection body is located on the other side of the opening direction or closing direction of the opening / closing body relative to the axis of the winding shaft for moving the opening / closing body open and closed.Therefore, it is possible to detect any irregular winding of the opening / closing body toward the main body earlier than when the tip of the detection body is located on either the opening direction or closing direction of the opening / closing body relative to the axis of the winding shaft, and the accuracy of the detection can be improved.
