Description

  The present invention relates to an opening / closing body control device that controls a predetermined operation of an opening / closing body device that electrically opens and closes an opening / closing member such as a screen installed in an opening of a structure housing including a building such as a building, factory, or warehouse.
Opening and closing devices such as screens, shutters, and doors that are installed at the opening of structures including buildings such as buildings, factories, and warehouses use electric screens, electric shutters, and electric doors that open and close electrically. Often done. As for the electric screen that electrically opens and closes, there is one described in Patent Document 1.
Japanese Patent Laid-Open No. 10-165530
  A device that electrically opens and closes an opening / closing member as in the past includes a wired operation switch (PBS) for controlling the operation and is often installed near the end of an outdoor opening. . Therefore, the PBS must be operated for each opening / closing operation. For example, in a warehouse, a cold storage, a heat storage, etc., the opening / closing body device is normally in a fully closed state for heat insulation, etc., and when a person or a vehicle passes, it is fully opened or a predetermined range is opened. It is necessary to do. In such a case, it may be troublesome to operate the PBS one by one. Furthermore, after a person or a vehicle has passed, it may be preferable that the fully closed state is maintained in order to maintain the internal heat insulation state. In particular, when passing while driving a vehicle, the PBS must be operated just before the opening and closing member, and the PBS must be operated after passing, which may be troublesome.
  The present invention has been made in view of the above points, and provides an opening / closing body control device capable of making the opening / closing operation of the opening / closing body easier to operate when a person or the like passes through the opening / closing body. There is to do.
  An opening / closing body control device according to claim 1 is provided with an opening / closing body means provided in an opening, and information detection means for detecting at least one of position information, speed information, and acceleration information when the opening / closing body means is moved. , If at least one of the position information, the velocity information, and the acceleration information detected by the information detection unit matches any one of a plurality of predetermined conditions, a predetermined corresponding to the matched condition And a control means for causing the opening / closing body means to perform the moving operation. In the case where the opening / closing body device winds up a sheet body, such as a screen device, the information detection means attaches a pulse encoder or the like to a rotating portion such as the winding drum, and the rotation position of the winding drum By detecting the rotational speed and rotational acceleration, information such as the moving position, moving speed, and moving acceleration of the sheet body is detected. This information is detected when the opening / closing member means is moved in the opening direction by hand, moved in the reverse direction immediately after being moved in the opening direction, or when the opening / closing member means comes into contact with an obstacle during its own weight drop. Since the information such as the movement position, the movement speed, and the movement acceleration corresponding to the operation of the opening / closing body means at that time is detected from the means, it is determined by determining whether or not this information meets a predetermined condition. It is possible to determine which operation has occurred. The control means controls the moving operation of the opening / closing body means according to the determination result. For example, when the operator manually moves the opening / closing member means in the opening direction, and determines that the moving position, speed, acceleration, etc. of the opening / closing member means at that time match predetermined conditions, Is operated to move the opening / closing body means in the opening direction, and the operation of the opening / closing body means is stopped when a predetermined position (for example, a fully open position) is reached. Thus, the operator can easily pass through the opening because the operator opens the opening / closing member simply by applying a slight force in the opening direction, for example, an upward force to the opening / closing member. It becomes like this. Note that the predetermined conditions are not set for all of the movement position, speed, and acceleration during the movement operation, but the conditions are set based on specific information such as the movement position and speed and the movement position and acceleration. You may do it. Detection of the moving position or the like may be performed by a rotating part of a driving mechanism such as an opening / closing machine or a motor. However, when the opening / closing body is moved manually or the like, it is necessary that the rotating portion is configured to rotate. As another means, a sensor or the like may be provided on the guide rail at predetermined intervals such as uniform, and the movement position or the like may be detected based on the cutting of the light beam, the next change, or the like.
  According to a second aspect of the present invention, the opening / closing body control device according to the first aspect is characterized in that the predetermined movement operation is an assist operation. Here, the assisting operation means that when the opening / closing body means in a predetermined closed state is moved in the opening direction by a predetermined force applied by others such as manual operation, the opening / closing body means is automatically moved thereafter. And moving to the predetermined position or moving in the opening direction for a predetermined distance or a predetermined time to stop. In addition to this operation, after the aforementioned stop state is maintained for a predetermined time, it may be returned to a predetermined closed state such as a fully closed state again. Note that the position to be stopped may be a fully open position. By the way, in the above description, it was a case where it was moved in the opening direction by a predetermined distance or the like, but the opening / closing body means in a predetermined open state (in other words, a predetermined closed state) was added from others such as manual operation. If the opening / closing means is automatically moved to a predetermined position or moved in the closing direction by a predetermined distance or a predetermined time after being moved by a predetermined force for a predetermined distance in the closing direction, In addition, after a predetermined time has elapsed, it may be restored to a predetermined open state such as a fully open state again. Of course, the above-described operation may be performed in the same way for both the opening direction and the closing direction.
  The opening / closing body control apparatus according to a third aspect is characterized in that, in the first aspect, the predetermined movement operation is a free stop operation. Here, the free stop operation means that the opening / closing body means in the stopped state (including the fully closed / fully opened state) is manually moved in the opening direction or the closing direction, and after that movement, a predetermined distance in the direction opposite to the moving direction is obtained. This is a series of operations for bringing the opening / closing member means into a stopped state at a position moved in the opposite direction when it is moved only by that amount.
  According to a fourth aspect of the present invention, the opening / closing body control device according to the first aspect is characterized in that the predetermined movement operation is an obstacle sensing operation. The obstacle sensing operation here is a series of operations in which the opening / closing member means is reversed and moved in the opening direction for a predetermined distance or a predetermined time when a person or an obstacle comes into contact with the closing opening / closing member means. It is the operation of. In addition, you may make it a stop state in the position which contact | abutted, without performing reverse operation. When performing obstacle detection operation and moving in the opening direction for a predetermined distance or time at the time of obstacle detection, the movement amount when moving in the opening direction by assist operation is the movement amount in the opening direction in obstacle detection operation It is preferable to increase the amount. In the obstacle sensing operation, it is sufficient to secure the opening amount in order to reduce the influence on the obstacle as much as possible. This is because securing is one of the purposes.
  According to the opening / closing body control device of the present invention, there is an effect that the opening / closing operation of the opening / closing body can be made easier to operate when a person or the like passes through the opening / closing body.
  Preferred embodiments of an opening / closing body control device according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, a screen device that is controlled to be opened and closed vertically will be described as an example of the opening / closing member means. FIG. 1 is a diagram showing a schematic configuration of an opening / closing body control device of the present invention. FIG. 2 is a side view of FIG.
  This screen device is provided in an opening of a building, and basically includes a screen box 11, a sheet body 12, guide rails 13 and 14, a motor 15, an opening / closing body control device 16, and the like.
  The guide rails 13 and 14 are provided on the left and right ends of the opening of the building so as to be in contact with both ends of the sheet body 12, and the cross-sectional shape spanned from the upper end of the opening to the floor surface is a substantially U-shaped guide. It is comprised with the metal members which have a groove | channel. A screen box 11 into which the upper end portions of the left and right guide rails 13 are inserted is provided on an upper side wall portion such as an upper casing of the opening. The lower end of the screen box 11 has left and right guide grooves that open to communicate with the guide grooves of the left and right guide rails 13, respectively.
  Further, a winding shaft 18 having a winding drum 17 in the left-right direction is provided in the screen box 11 at both end brackets (not shown) so as to rotate and wind up or unwind the sheet body 12. The winding shaft 18 is provided with the following elastic member (specifically, a return coil spring). The elastic member accumulates a return elastic force by the rotation of the winding shaft when the shutter curtain is extended downward. The torque around the winding shaft due to the return elastic force of the elastic member may be smaller than the torque around the winding shaft due to the downward closing movement force based on the weight of the shutter curtain (including the seat plate). is necessary. Further, the torque around the winding shaft due to the return elastic force of the elastic member is the downward closing movement force based on the own weight obtained by subtracting at least part of the weight of the front end of the closing direction such as the seat plate from the own weight of the shutter curtain. It is necessary to set the torque larger than the torque around the winding shaft. For example, by using a shutter curtain as a lightweight member such as a sheet body rather than a relatively heavy material such as an iron slat curtain, the elastic member can achieve a torque that satisfies the above-described conditions. It becomes easy to constitute.
  As described above, the torque around the take-up shaft is constituted by the return elastic force of the elastic member. Normally, the shutter curtain (including the seat plate) moves in the closing direction under its own weight unless human power is applied. It is fully closed, and by applying a slight force in the opening direction, for example, an upward force, it is possible to provide a relatively trigger for the assist operation and the free stop operation. Moreover, since the accumulated elastic force can be used even during movement in the opening direction as an assist operation triggered by this, the switch can be downsized and power consumption can be reduced. In the case of normal closing, only the dead weight is sufficient. However, even if an opening / closing device is used in this case, the size can be reduced and the power consumption can be reduced.
  In this way, the sheet body 12 moves up and down along the guide grooves of the guide rails 13 and 14, and opens and closes the opening. The opening / closing operation here is a concept including a case where the power, the opening / closing device or the like is used only in a special case where the operation is performed manually, and there is an assist operation or brake restraint (or release). The chain 19 connects a main sprocket 20 provided on the rotating shaft of the motor 15 and a driven sprocket 21 provided on the rotating shaft of the winding shaft 18. Accordingly, the rotational driving force of the motor 15 is transmitted to the winding shaft 18 side via the main driving sprocket 20, the chain 19, and the driven sprocket 21, and when the motor 15 rotates, the winding shaft 18 also rotates, The opening / closing operation is controlled.
  One end portion (upper end portion) of a vertically movable sheet body 12 that shields the opening is fixed and wound around the winding drum 17, and the sheet body 12 is wound around the left and right guide rails 13 by rewinding the winding drum 17. It is guided and lowered to close the opening. The sheet body 12 is formed into a sheet shape with a single flame-retardant fabric made of glass cloth, silica cloth, or the like. A seat body 121 having a length substantially the same as the width of the sheet body 12 seated on the floor surface of the opening when the sheet body 12 is lowered is integrally attached to the lower end portion of the sheet body 12. The seat body 121 is formed in a rectangular shape in cross section, and the lower surface portion has a horizontal grounding surface that contacts the floor surface. In the take-up drum 17, a take-up ammunition machine that applies a biasing force to the take-up drum 17 in order to take up the sheet main body 12 is interposed in a state of being fitted around the take-up shaft 18. Therefore, in a normal state, the seat body 12 is urged in the closing direction by the weight of the seating body 121 and is closed by its own weight. When the seating body 121 is lifted manually, the seat body 12 is wound. The take-up machine winds up the take-up drum 17.
  The opening / closing body control device 16 has a microcomputer configuration and is supplied with power via a power line AC (not shown). The opening / closing body control device 16 can also control the rotation of the motor 15 on the basis of a control signal corresponding to the operation state of each operation button on an operation switch (not shown). 15 detects a moving position and a moving state in the opening of the sheet body 12 based on a signal from the rotation detector 22 provided in the motor 15, and controls the opening / closing operation of the sheet body 12 by driving the motor 15 based on the detected position. It is what you do. In this embodiment, the rotation detector 22 is composed of a pulse generation type rotary encoder. When the generation type rotary encoder is used, the rotational position of the motor 15 and the position of the winding shaft 18 and the opening of the seating body 121 are obtained by calculation based on the generation state of the pulse. As the rotation detector 22, an absolute encoder that can detect the absolute rotational position of the motor 15, that is, the absolute position in the opening of the winding shaft 18 or the seating body 121 may be used. .
Next, an operation example of the opening / closing body control device of the present invention will be described with reference to the flowchart of FIG.
[Step S31]
It is determined whether or not a pulse is generated from the rotation detector 22, and if generated (yes), the process proceeds to step S32. If not generated (no), the process returns to return to this step. Repeat the process.
[Step S32]
The frequency of pulse generation from the rotation detector 22 is grasped and stored.
[Step S33]
Based on the generation frequency of the pulses output from the rotation detector 22 stored in the previous step, the movement state such as the position of the sheet 12 in the opening, the speed at the time of movement, and the acceleration is grasped.
[Step S34]
It is determined whether or not the position of the sheet body 12, the moving speed, the acceleration, and the like grasped in the previous step S33 meet predetermined conditions. If they agree (yes), the process proceeds to the next step S35, Otherwise (no), the process returns to step S31.
[Step S35]
Based on the condition of the previous step S34, the next process is distributed. If the condition for the assist function is met, the process proceeds to step S36. If the condition for the free stop function is met, the process proceeds to step S41. If the condition for the obstacle sensing function is met, the process proceeds to step S45. The processing from step S36 to step S39 is a series of processing executed when the assist function condition is met. The processing from step S40 to step S43 is a series of processing executed when the free stop function condition is met. The processing from step S44 to step S46 is a series of processing executed when the condition of the obstacle sensing function is met.
  Here, the assist function means that when the sheet body 12 in the closed state as shown in FIG. 4 (A) is moved manually by the predetermined distance as shown in FIG. The body 12 is automatically fully opened as shown in FIG. 4 (C) to FIG. 4 (D), temporarily stopped in the fully opened state of FIG. 4 (D), and then passed through FIGS. 4 (E) and 4 (F). This is a series of operations for returning to the fully closed state as shown in FIG. Here, when the position of the sheet body 12 moves from the fully closed state in the opening direction by a predetermined distance at a predetermined speed, it is determined that the condition of the assist function is met.
  With the free stop function, the sheet body 12 in the stopped state (closed state in the figure) as shown in FIG. 5A is manually opened, and the sheet body 12 moved in the opening direction as shown in FIG. 5B is opened. When the sheet body 12 is moved by a predetermined distance in the closing direction that is opposite to the direction, the sheet body 12 is then stopped at the position where the sheet body 12 is moved in the opposite direction as shown in FIG. It is a series of such operations. Here, when the sheet body 12 is reversely moved in the reverse direction (closed direction) in the middle of the opening direction, it is determined that the condition of the free stop function is met. Even when the sheet body 12 in the stopped state (including the fully opened state) is moved in the closing direction and then moved in the opening direction that is opposite to the closing direction, the sheet body 12 may be in the stopped state as well. Good.
  The obstacle detection function is such that when a person or an obstacle comes into contact with the seating body 121 of the closed sheet body 12, the sheet body 12 is reversed and moved in the opening direction for a predetermined distance or a predetermined time. It is a series of operations. Here, when the sheet body 12 stops in the middle while moving in the closing direction, it is determined that the condition of the obstacle detector function is met.
[Step S36]
Since the sheet member 12 has been moved manually in the opening direction as shown in FIG. 4B from the fully closed state as shown in FIG. 4A, it is determined in the previous step S35 that the conditions of the assist function are met. . Accordingly, the motor 15 is driven, and the sheet body 12 is moved in the opening direction by the driving force of the motor 15 from the state shown in FIG. 4B. After passing through FIG. 4C, the sheet body 12 is fully opened as shown in FIG. It becomes a state.
[Step S37]
In order to maintain the fully open state as shown in FIG. 4D, the process waits until a predetermined time elapses.
[Step S38]
Since the predetermined time has passed, release the brake.
[Step S39]
When the brake is released, the sheet body 12 descends against its urging force of the return coil spring, which is an elastic member, by its own weight, so that the figure is shown in FIGS. 4E and 4F from the fully opened state of FIG. 4 (A) becomes a fully closed state. At this time, the process returns to step S31, and the processing of step S31 to step S34 is executed, so that the determination as to whether or not the other function is satisfied is repeated, and the fully closed state of FIG. Will come back.
[Step S40]
Since the sheet body 12 moved in the opening direction as shown in FIG. 5B from the fully closed state as shown in FIG. 5A has been moved by a predetermined distance in the closing direction opposite to the opening direction. In the previous step S35, it is determined that the free stop function condition is met. Therefore, the operation of the seat body 12 is restricted by the brake. As a result, the sheet body 12 is stopped at a position moved in the reverse direction as shown in FIG.
[Step S41]
A pulse is generated from the rotation detector 22 by manually moving the sheet body 12 that has been stopped in the previous step S40 in the closing direction. Therefore, it is determined whether or not this pulse has occurred. If it occurs (yes), the process proceeds to the next step S42, and if not (no), it operates so as to maintain the stopped state until a pulse is generated.
[Step S42]
Since it is determined in the previous step S41 that a pulse has been generated from the rotation detector 22, the brake is released.
[Step S43]
Since the seat 12 is lowered by its own weight due to the release of the brake, the process returns to step S32 so as to return to the fully closed state of FIG. 5A while repeatedly determining whether or not it matches other functions. become.
[Step S44]
When the obstacle 60 exists on the floor surface of the opening as shown in FIG. 6A, the sheet body 12 moves in the closing direction as shown in FIG. When the seat body 121 of the body 12 comes into contact, the moving speed of the seat body 12 becomes slow at the contact position, and stops at the contact position, so that the condition of the obstacle detection function is met in the previous step S35. To be judged. Therefore, the operation of the seat body 12 is restricted by the brake. As a result, the sheet body 12 is stopped as shown in FIG.
[Step S45]
The motor 15 is driven from this stop state, and the seat body 12 is moved in the opening direction by a predetermined amount or a predetermined time from the state shown in FIG. Avoid contact.
[Step S46]
As shown in FIG. 6C, the operation is performed so as to maintain the stop state at the position after the movement in the previous step S45, and the process jumps to step S41. After shifting to step S41, whether or not a pulse is generated from the rotation detector 22 by moving the sheet body 12 in the stopped state in the closing direction by hand as shown in FIG. If the pulse is generated (yes), the process proceeds to the next step S42. If not (no), the stop state is maintained until the pulse is generated. Then, the pulse is generated from the rotation detector 22. If it is determined, the brake is released and the seat body 12 descends by its own weight, and the determination as to whether or not it matches other functions is repeated and returned to the fully closed state.
  In the above-described embodiment, instead of jumping from step S46 to step S41, the routine may jump to step S37. In this case, as shown in FIG. 6C, the sheet body 12 in the stopped state starts to drop its own weight as the predetermined time elapses. In step S45, the case of moving in the opening direction has been described, but the stop state may be maintained at a position in contact with the obstacle. Also, when it comes into contact with an obstacle, it starts to descend again after moving in the opening direction by a predetermined amount or a predetermined time, and only when it comes into contact with the obstacle again at the same position at that time You may make it be a stop state. Further, when the sheet body 12 is moved manually from the stopped state, the opening operation or the closing operation by the assist function as described above may be performed according to the moving direction. In the above-described embodiment, when a predetermined time has elapsed or a pulse is generated, the brake is released and the seat body is lowered by its own weight. If it detects, you may make it perform closing operation by dead weight fall immediately.
  In the above-described embodiment, the case where the sheet main body is drawn out from the upper side by the lowering method has been described. However, the invention can be similarly applied even when the sheet main body is drawn out by the uppering method. Furthermore, the present invention can be similarly applied even if the shutter-like opening / closing member is extended by a horizontal pulling method or is extended by a horizontal method. Examples of the opening / closing device include a shutter device, a blind device, a roll screen device, a hanging curtain device, a sliding door device, a moving partition device, an awning device, and a waterproof plate device. If the opening / closing body is moved laterally or the like, a brake for preventing the opening / closing body from moving is not essential if the opening / closing body does not move or hardly moves unless force is applied. The motor that drives opening and closing may be a rotary type or a linear motor. In addition, when using a linear motor for the shutter etc. which move to an up-down direction, it is preferable to provide along a guide rail, for example.
