Can be constructed.

On the other hand, as shown in FIGS. 2 and 3, the mover block 3 which constitutes a linear motor together with the stator block 2 is arranged so as to face each coil 4 of the stator block 2 and the coil 4 A permanent magnet 51 in which magnetic poles of different polarities are alternately arranged in the longitudinal direction of the gate 31 is provided on the surface opposite to. The permanent magnet 51 is vertically magnetized, and a yoke plate 52 is fixed to a lower surface of the permanent magnet 51. The length of the yoke plate 52 in the longitudinal direction of the gate 31 is longer than that of the permanent magnet 51, and both ends of the yoke plate 52 are fixed to the upper surface of the sliding door body 10 by fasteners 53 such as screws. The permanent magnet 51 is formed by arranging a plurality of vertically magnetized permanent magnets in the longitudinal direction of the gate 31 (longitudinal direction of the yoke plate 52), or by performing multipolar magnetization on a magnetic material. The pitch of the magnetic poles formed on the surface of the permanent magnet 51 facing the coil 4 is set to two thirds of the pitch of the coil 4. Therefore, by changing the energization state of the coil 4 sequentially according to the polarity of the permanent magnet 51 detected by the Hall IC 6, the stator block 2

As described above, since the stator block 2 and the mover block 3 as the elements constituting the linear motor are separately provided in the Kamoi 31 and the sliding door body 10, respectively, it is conventionally used. By attaching the mover block 3 to the sliding door body 10 and using the Kamoi 31 containing the stator block 2, a sliding door driven by a power source can be constructed.
Can be formed to have the same dimensions as a manual sliding door, so that the replacement of the manual door 31 allows the manual sliding door to be replaced with an electric sliding door.

The mover block 2 includes the plurality of coils 4 as described above, and includes the substrate 41 on which the Hall IC 6 is mounted. In order for the mover block 3 to travel with respect to the stator block 2, it is necessary to control the timing of energizing the coil 4 based on the output of the Hall IC 6. Therefore, a controller 7 is provided to control the timing of energizing the coil 4. The controller 7 is housed in the housing 61 as shown in FIGS. 12 and 13, and as shown in FIGS. 5 and 6, forms a concave groove 37 on one side in the width direction of the wide portion of the Kamoi 31. Is stored in a non-existent area. That is, the controller 7 is arranged near the center in the width direction at the opening of the building. In addition, the lower surface of the housing 61 of the controller 7 is aligned with the lower surfaces of other parts of the Kamoi 31. By arranging the housing 61 at such a position, the controller 7 is provided at a position where it is easy to work when operating and maintaining the controller 7.

The controller 7 has the configuration shown in FIG.
DC power rectified and smoothed by the rectifying and smoothing unit 73 via
Coil 4 of stator block 2 through power output section 74
It is configured to give to. The power output unit 74 controls the timing of energizing the coil 4 in accordance with an instruction from the output control unit 70. The output control unit 70 includes, in addition to the Hall IC 6 described above, an output of a human sensor 75 that detects the presence or absence of a person using a heat ray radiated from a human body, and a receiving unit 76a that receives a wireless signal using infrared rays as a transmission medium. ,
The output of 76b is input. The output control unit 70 includes a microcomputer as a main component, and is supplied with power in which the output voltage of the rectifying and smoothing unit 73 is stabilized by the control power supply unit 77.

The above-described motion sensor 75 is a passive motion sensor using a pyroelectric infrared sensor, and receives a heat ray radiated from a person and generates a change in the heat dose by a predetermined amount or more. To change the output. This type of motion sensor is passive and does not require the function of irradiating the object with infrared rays, so its configuration is simple, and it does not require cooling or the like, and is inexpensive, space-saving, and easy to handle. . The detection area of this type of motion sensor 75 can be easily set by optically controlling the visual field, and the detection area can be set in a well-balanced manner around the opening. Also, one window 62 through which infrared light passes is connected to the controller 7.
Can be formed on the lower surface of the housing 61.
No protrusion is formed around the opening, so that the presence of the motion sensor 75 does not cause any protrusion to be formed in the opening, and does not hinder passage through the opening. . The window 62 is formed at the center of the housing 61 in the longitudinal direction, and the controller 7 is located near the center of the sliding door body 10 in the traveling direction at the opening where the sliding door body 10 opens and closes. Can be formed in a well-balanced manner.

On the other hand, two receivers 76a and 76b are provided, but only one receiver 76a is housed in the housing 61, and the other receiver 76b is housed in a separately provided case 63. A light receiving window 64 is formed on the lower surface of the housing 61 adjacent to the window 62, and the wireless signal enters the receiving unit 76 a through the light receiving window 64. Like the window 62 for the human sensor 75, the light receiving window 64 does not have a protrusion, and therefore does not hinder passage through the opening.

By the way, the output control unit 70 moves the sliding door main body 10 so as to open the opening while the presence of a person is detected by the human sensor 75, and when the sliding door main body 10 reaches the fully open position, the coil is controlled. 4 is stopped so that the sliding door main body 10 is kept at the fully open position. Further, the sliding door main body 10 is moved so as to close the opening after the presence of a person is no longer detected by the human sensor 75. Here, the closing timing of the sliding door main body 10 starts from the point in time when the presence of a person is no longer detected by the human sensor 75, and then the sliding door main body 10 is closed after a certain time has elapsed.

The output control unit 70 controls the running of the sliding door body 10 according to the content of the wireless signal received by the receiving unit 76a. That is, the opening and closing of the sliding door body 10 can be instructed by a wireless signal. The receiving unit 76b not housed in the housing 61 functions equivalently to the receiving unit 76a, and the output control unit 70 controls the opening and closing of the sliding door body 10 also by the wireless signal received by the receiving unit 76b. Indicator lights 66a and 66b made of light emitting diodes are arranged on the lower surface of the housing 61 of the controller 7 near the window 62 and the light receiving window 64. The indicator light 66a is turned on at the time of power supply to indicate whether or not power is normally supplied, and the indicator light 66b is when a person is detected by the motion sensor 75 or when a wireless signal is received from the remote control device. To be lit. The indicator lamps 66a and 66b are also used as abnormality notification means described later. The indicator lights 66a and 66b are exposed on the lower surface of the gate 31 and are installed in a place with good visibility.

Receiving sections 76a and 76b output binary signals of H level and L level in response to the wireless signal, and output while the power is supplied from commercial power supply 71 and the wireless signal is not received. Are set to the H level. On the other hand, the output control unit 70 includes the receiving units 76a, 76
Abnormality detecting means 70a for monitoring the presence or absence of an abnormality of b is provided. In the abnormality detecting means 70a, when the output level of the receiving units 76a and 76b is at the L level for a predetermined time, an abnormality occurs in the receiving units 76a and 76b. The indicator lamps 66a and 66b are turned on and off. That is, the receiving unit 76
If the wires a and 76b are disconnected or if the components of the receivers 76a and 76b are damaged, the receivers 76a and 76b may be damaged.
6b cannot maintain the output level at the H level,
Since the output level becomes L level, this state is
It is determined that there is an abnormality in 6a and 76b, and is notified.

As described above, the provision of the means for notifying the receivers 76a and 76b when there is an abnormality is provided, so that there is no abnormality in the receivers 76a and 76b and the reception of wireless signals and the detection of a person by the human sensor 75 can be performed. If it is indicated by the indicator light 66b, it is estimated that the failure of the linear motor is not the failure of the controller 7, and if the indicator light 66a is not turned on, it is estimated that the failure of the power supply system. If the detection of a person by 75 is not indicated by the indicator light 66b, it can be estimated that the controller 7 has failed. In this way, by detecting the presence or absence of an abnormality in the receiving units 76a and 76b and informing the user, it is easy to estimate the location where the abnormality has occurred.

Here, the case 6 for storing the receiving section 76b
3 has a light receiving window 65 at the center in the longitudinal direction through which a wireless signal passes as shown in FIG.
Reference numeral 3 is arranged near the center in the longitudinal direction of the gate 31 as shown in FIG. However, the position to attach the case 63 is
The housing 6 sandwiches the traveling rail 36 on which the sliding door body 10 travels.

As described above, by providing the receiving portions 76a and 76b on both sides of the sliding door body 10, it is possible to instruct the opening and closing of the sliding door body 10 by a wireless signal from either the front or back of the sliding door body 10. The area where the remote control device for transmitting the signal can be used is widened.

By the way, lids 61a and 61b are detachably attached to both longitudinal ends of the casing 61 of the controller 7, respectively. One lid 61a covers a connection portion connected to the stator unit 2, and a signal connector 78 and a power supply connector 79 are housed in this portion. 8, a connection line 81 is connected to the connector 78, and the connection line 81 is connected to the connector 45a as shown in FIG. Also, as shown in FIG.
And the connection line 82 is connected to the connector 45b as shown in FIG.
Connected to. These connection lines 81 and 82 are wired inside the gate 31 and need not be wired outside the gate 31. In other words, no wiring other than the power supply wire is required at the time of construction, and wiring construction is easy.

A power switch 72 and a power terminal 77 are provided at a position corresponding to the other lid 61b.
7 is concealed by the lid 61b,
Is exposed on the lower surface side through the lid 61b. The power terminal 77 has a quick connection terminal structure,
When the lid 61b is removed, the operation hole 77b for operating the wire insertion port 77a and the release button (not shown) is exposed. Here, the quick-connecting terminal structure is a locking spring (not shown) made of a leaf spring.
The connection and removal of the wire are performed by simply inserting the wire from the wire insertion port 77a, and the connection and removal of the wire are performed by the locking spring. Also, if a tool such as the tip of a flathead screwdriver is inserted into the operation hole 77b and the release button is pressed, the release button bends the locking spring so that the wire holding by the locking spring can be released. It is configured.

However, at the time of construction, if the electric wire for supplying power is inserted into the electric wire insertion port 77a and the cover 61b is attached, the electric wire is not exposed, and only the operation part of the power switch 72 is connected to the gate 3.
1 will be exposed on the lower surface. Since the power switch 72 is exposed on the lower surface side of the gate 31 as described above, the operation of the power switch 72 is facilitated. The electric wire is drawn out from the vicinity of the end of the Kamoi 31 to the outside of the Kamoi 31 and wired in the wall. That is, since the casing 61 of the controller 7 containing the human sensor 75 and the receiver 76a and the case 63 containing the receiver 76b are housed in the gate 31, the human sensor 75 and the receivers 76a and 76b are stored. Wiring, the wiring between the controller 7 and the stator block 2, etc.
Are performed inside the factory and these are assembled at the factory,
There is no need for complicated wiring work during construction. As a result, only wire for power supply needs to be wired at the time of construction on site, and wiring work on site becomes easy.
As described above, the Kamoi 31 used in the present embodiment is also used.
Is almost the same size as the manual sliding door, so only the Kamoi 31 is replaced for the manual sliding door, and the sliding door body 10
The electric sliding door can be configured by simply attaching the mover block 3 to the upper surface of the sliding door, and an existing manual sliding door can be replaced with an electric sliding door at low cost.

In the above embodiment, a single sliding door has been exemplified. However, a similar structure can be adopted for a sliding door. Also, an example has been described in which both indicator lights 66a and 66b are simultaneously blinked when the receivers 76a and 76b are abnormal. However, the present invention is not limited to this. Or means for notifying by sound.
