Abstract

PROBLEM TO BE SOLVED: To provide a gate device that eliminates electrical wiring for moving along opening/closing operations of a gate bar, while incorporating a reset driving part on the gate bar side that is opened and closed, the gate device including a power supply mechanism for the reset diving part that ensures durability to withstand the operations.SOLUTION: A gate device starts a reset operation of a gate bar 7 when the gate bar 7 comes into a released state. In the reset operation, a reset driving arm rotates the gate bar 7 in a release direction and moves the gate bar to a release completion state withdrawn from a driveway. While the reset driving arm keeps the gate bar 7 in a release completion state, a horizontal rotary shaft 9 rotates a gate bar base part 6 in a direction to erect the gate bar base part. While the gate bar base part 6 is erected, the reset driving arm performs a reset operation to return to a fixed state in which the gate bar 7 rotates in a reverse direction of the release direction and shifts to a fixed state. Especially to note is that a reset driving part 8 is operated by driving electric power supplied by a main body enclosure 4, by non-contact power feeding.SELECTED DRAWING: Figure 7

Description

  The present invention relates to a gate device that restricts the passage of a vehicle or the like at a toll gate on a highway or a toll road, or an entrance / exit of a parking lot, and more particularly to a gate device that automatically returns a released gate bar.

  2. Description of the Related Art Conventionally, gate devices are installed, for example, at ETC (Electronic Toll Collection System) gates at toll gates on expressways and toll roads and at entrances and exits of toll parking lots. The gate device regulates the passage of the vehicle by lying down on the gate bar (in a closed state) and blocking the roadway. Normally, the vehicle does not collide with a gate bar that blocks the road. However, for example, when a vehicle that has forgotten to insert an ETC card into the ETC on-board unit passes through the gate of the ETC, or when the vehicle entering from the parking lot exits without waiting for the gate bar to open intentionally or negligently For example, the vehicle may collide with the gate bar. Some gate devices rotate (release) the gate bar in the vehicle traveling direction when the vehicle collides in order to prevent the gate bar from being damaged by the vehicle collision. Some gate devices return a released gate bar automatically or remotely.

  For example, in the vehicle traffic breaker disclosed in Patent Document 1, it is intended to quickly return a blocking rod after a release operation with a simple configuration, and the vehicle is blocked by a return drive unit and the return drive unit. A blocking rod that is rotated between a position and a permission position that allows the vehicle to move and opens and closes, a release shaft that rotates the blocking rod in a release direction that releases an impact by the vehicle, and the blocking rod is released A transmission mechanism that transmits the rotation of the return drive unit to the release shaft only when it rotates in the direction, and the release shaft rotates by the rotation of the return drive unit, so that the blocking bar is in the direction opposite to the release direction. A technique that is configured to rotate in a certain return direction is disclosed.

  Further, the vehicle traffic breaker disclosed in Patent Document 1 includes a breaker body, a support arm supported by the breaker body, and a blocking bar supported by the support arm, and further includes a return drive unit, a control unit In the circuit breaker provided with the portion, the power for rotating the support arm to open and close the blocking bar and the power for causing the blocking bar to return are separately provided.

JP 2012-17643 A

  However, in the vehicle traffic breaker disclosed in Patent Document 1, when the return operation from the release state is performed, the raising operation of the arm portion and the recovery operation of the blocking rod to the non-released state are performed at the same time. In order to take an irregular movement trajectory of rising while projecting (projecting) greatly on the roadway side, there is a risk that the following vehicle may collide with the blocking rod during the recovery operation.

  In addition, in the vehicle traffic breaker disclosed in Patent Document 1, power for opening and closing the blocking rod and power for causing the blocking rod to return are separately provided, so that the blocking rod is moved to the roadway side when the blocking rod is restored. Control that does not protrude is possible. However, since the mechanism that causes the blocking rod to return is attached to the support arm, it is necessary to route the power supply wiring for supplying drive power to the mechanism from the power supply provided on the breaker body side to the support arm side. There is. This power supply wiring is pulled, pushed, or dragged with the rotation of the support arm during the normal opening / closing operation of the blocking rod. In particular, in a vehicle traffic breaker for restricting the passage of ETC lanes, it is required to open and close several tens of thousands of times a day, but the power supply wiring bends and expands with the support arm that opens and closes at high speed. It is gradually deteriorated by repeating many times, and finally it is broken by opening and closing operations several thousand times. As described above, the conventional gate device has a problem that the durability of the operation of the gate device cannot be maintained for a long time without satisfying the durability of the power supply wiring required for operation.

  On the other hand, for example, it is conceivable to use a power supply mechanism of a sliding contact system using a brush and a slip ring. However, in an environment where fine particles such as moisture and dust are dancing, such as outdoor parking lots and toll road toll booths, if a sliding contact type power supply mechanism is used, it will be ignited by sparks at the time of contact. There is a risk of causing disasters. Further, if a waterproof cover, a dust-proof cover, or the like is provided in order to avoid this danger, the cost is increased and the size of the equipment is increased. Furthermore, the sliding contact type power supply mechanism is required to have substantially perfect waterproof properties in a rough weather environment such as rain or typhoon. Then, since it is necessary to provide a high-performance waterproofing equipment, further cost increase and enlargement of equipment will be caused.

  The present invention has been made in view of, for example, the above-described problems, and an object of the present invention is to reduce the mechanism space for returning the released gate bar, and the position of the gate bar during the returning operation. Can be quickly stabilized, and the gate bar during the return operation can be prevented from projecting to the roadway side, and a compact and inexpensive gate device can be realized, and the return drive unit can be opened and closed on the gate bar side. It is an object of the present invention to provide a gate device including a power supply mechanism for a return drive unit that ensures operation durability by eliminating the need for a power supply wiring that can be moved in accordance with the opening / closing operation of the gate bar.

  In order to solve the above-described problem, a first gate device of the present invention is a gate device that restricts the passage of a moving body on a road, and is opposite to a main body and a moving body traveling direction parallel to the road.

The following embodiments are preferable specific examples of the present invention and disclose various preferable techniques, but the technical scope of the present invention is not limited to these embodiments.

  First, the gate device 1 according to the first embodiment of the present invention will be described. As shown in FIGS. 1 to 4, the gate device 1 is a vehicle that travels on the roadway 2 by a gate bar 7 at a gate such as a toll gate on a highway or a toll road or an entrance / exit of a toll parking lot (moving) For example, it is installed on an island 3 which is a concrete platform formed along the roadway 2.

  FIG. 1 shows a state (closed state) where the gate bar 7 is closed and the roadway 2 is blocked, and FIG. 2 shows a state (open state) where the gate bar 7 is opened and the roadway 2 is opened. 3 shows a state in which the gate bar 7 is released, and FIG. 4 shows an intermediate state in the release return operation of the gate bar 7. In the following, for convenience of explanation, when the gate is viewed from a point on the road 2 before the passage of the gate, that is, in the traveling direction of the vehicle on the road 2, the front side is “front” and the other side (back side) ) Is “back”, the right side is “right”, the left side is “left”, the upper side is “up”, and the lower side is “lower”. A vehicle traveling on the roadway 2 normally approaches the gate device 1 from the front of the gate device 1, and then proceeds to the rear of the gate device 1. That is, the front-rear direction of the gate device 1 is a vehicle traveling direction (moving body traveling direction) parallel to the roadway 2.

  The gate device 1 includes a main body housing 4 (main body portion) formed in a rectangular column shape, and the main body housing 4 is fixed on the island 3 by a main body base 5. Further, in the gate device 1, the gate bar base 6 and the gate bar 7, which are members that block the roadway 2, and the return drive unit 8 are attached to the horizontal rotation shaft 9 provided on the upper front side of the main body housing 4. . In the first embodiment, the gate device 1 is a fixed type composed of a power feeding unit 16 and a power receiving unit 17 to be described later in order to supply power from the main body housing 4 side to the return drive unit 8 by non-contact power feeding. A non-contact power feeding mechanism 15 is provided.

  The main body housing 4 includes a horizontal rotation shaft 9 extending in the horizontal direction (front-rear direction), a gate drive motor 51 for driving the horizontal rotation shaft 9 together with the gate bar base 6 and the gate bar 7 (FIGS. 7 and 11). And a gate driving mechanism. Furthermore, the main body housing 4 includes a main body control unit 10 (see FIGS. 7 and 11) for overall control of the gate device 1, and power is supplied to the power receiving unit 17 of the return drive unit 8 by non-contact power feeding. Is provided on the front surface. The gate drive motor 51 and the main body control unit 10 will be described later.

  The horizontal rotation shaft 9 is disposed so as to protrude forward (opposite to the vehicle traveling direction) from the inside of the main body housing 4 through the opening on the front surface of the main body housing 4. The horizontal rotation shaft 9 is electrically connected to the gate drive motor 51 inside the main body housing 4 (see FIG. 7), and is driven by the gate drive motor 51 to rotate. The gate bar base 6 and the gate bar 7 attached to can be integrally rotated. Accordingly, the horizontal rotation shaft 9 can perform an opening / closing operation (vehicle opening / closing operation) of the roadway 2 by rotating the gate bar 7.

  This road opening / closing operation is an operation of blocking / opening the road 2 by causing the gate bar base 6 and the gate bar 7 orthogonal to the horizontal rotation shaft 9 to lie down and stand upright. As shown in FIG. 1, when the horizontal rotation shaft 9 is rotated by the gate drive motor 51 to lie down on the gate bar base 7, the gate bar 6 is laid down together with the gate bar base 7, thereby blocking the roadway 2. Thus, the position where the gate bar base 6 and the gate bar 7 lie down is referred to as a “side-down position”. On the other hand, as shown in FIG. 2, when the horizontal rotation shaft 9 is rotated by the gate drive motor 51 to raise the gate bar base 6, the gate bar 7 is raised together with the gate bar base 6, thereby opening the roadway 2. The In this way, the position where the gate bar base 6 and the gate bar 7 stand up is referred to as “standing position”.

  The gate bar base portion 6 is a long member formed in a U-shaped cross-section with an opening on the front side, and has a shape that fits one end side of the gate bar 7. The rear surface of the gate bar base portion 6 on one end side in the longitudinal direction (for example, the right side) is fixed to the horizontal rotation shaft 9 and can be rotated with respect to the main body housing 4 according to the rotation of the horizontal rotation shaft 9. It has become. On the other hand, the other end side (for example, the left side) in the longitudinal direction of the gate bar base portion 6 extends in a direction intersecting with the horizontal rotation shaft 9 (for example, a direction orthogonal to the horizontal rotation shaft 9).

  Further, the gate bar base portion 6 is provided with a locking movable portion 12 and the like as a locking mechanism 11 for detachably locking the fitted gate bar 7 on one end side in the longitudinal direction, and short on the other end side in the longitudinal direction. A release shaft 13 is provided that extends in the hand direction (for example, the vertical direction when the gate bar 7 is closed). A round recess 13a slightly thinner than the shaft diameter is formed on the lower surface of the release shaft 13 (see FIG. 5). The circular recess 13a has a shape for fitting a return drive shaft 32 of the return drive unit 8 to be described later, and the lower surface of the gate bar base 6 and the return drive unit 8 are made coaxially with the release shaft 13 and the return drive shaft 32. It is for positioning. Note that positioning bosses, mounting screws (not shown), or the like may be used for positioning the gate bar base 6 and the return drive unit 8.

  Further, the gate bar base portion 6 includes a stopper portion 14 on the other end side in the longitudinal direction and on the rear surface side (see FIG. 7 and the like). The stopper portion 14 is a cushion made of, for example, foamed urethane or the like, and has a surface parallel to the longitudinal direction of the gate bar base portion 6. The stopper part 14 is arrange | positioned on the rotation track | orbit of the contact part 22 of the return driven part 21 mentioned later.

  The gate bar 7 is formed in a long bar shape, and has a length that can block the roadway 2 in the closed state. The gate bar 7 is provided on one end side in the longitudinal direction (for example, the right side in the closed state), and attached to the gate bar holding unit 18 and extends to the other end side in the longitudinal direction (for example, the left side in the closed state). And a gate bar main body 19. The gate bar body 19 is formed by covering the other end side of a core made of a lightweight material, for example, an aluminum hollow pipe, with a cushioning material made of foamed urethane or the like. In order to improve visibility from a driver or the like, a laminate such as red and white stripes may be applied to the outer surface portion of the cushioning material constituting the gate bar main body 19.

  The gate bar 7 is attached to the gate bar base portion 6 via a gate bar holding portion 18 on one end side in the longitudinal direction. Specifically, one end in the longitudinal direction of the gate bar holding portion 18 is detachably held by the gate bar base 6, and the other end in the longitudinal direction of the gate bar holding portion 18 is pivotally supported by the release shaft 13 of the gate bar base 6. Yes.

  As shown in FIG. 1 and FIG. 2, the gate bar 7 is normally fitted with a gate bar holding portion 18 on one end side in the longitudinal direction on the gate bar base portion 6, and one end side in the longitudinal direction of the gate bar holding portion 18 on the locking mechanism 11. Thus, the gate bar base 6 is locked and integrated with the gate bar base 6 to be in a fixed state (non-release state). At this time, the longitudinal direction of the gate bar 7 is aligned with the longitudinal direction of the gate bar base 6, and the other longitudinal end of the gate bar 7 is greatly extended in a direction intersecting (orthogonal to) the horizontal rotation shaft 9.

  The gate bar 7 is shown in FIG. 3 and the like when one end in the longitudinal direction of the gate bar holding portion 18 is removed from the gate bar base portion 6 and the integrated fixing (fixed state) with the gate bar base portion 6 is released (released). So that it is in the released state. The released gate bar 7 (gate bar holding portion 18) is rotatable about the release shaft 13 with respect to the gate bar base portion 6.

  The operation of releasing the gate bar 7 and rotating with respect to the gate bar base 6 in this way is hereinafter referred to as “release operation”. Further, the released gate bar 7 rotates about the release shaft 13, and one end portion in the longitudinal direction of the gate bar 7 is separated from the gate bar base portion 6 and the other end portion in the longitudinal direction of the gate bar 7 is directed in the vehicle traveling direction. The direction (clockwise direction when viewed from above) is referred to as “release direction”. Further, the released gate bar 7 is rotated about the release shaft 13 and retracted from the roadway 2, for example, about 90 degrees around the release shaft 13 and the longitudinal direction is substantially the same as the roadway 2. The parallel state (see FIG. 3) is referred to as a “release complete state”.

  The gate bar holding portion 18 includes, for example, a latch portion 20 and the like on one end side in the longitudinal direction as a locking mechanism 11 for detachably locking the gate bar 7 to the gate bar base 6. That is, between the gate bar base portion 6 and the gate bar 7, a locking mechanism 11 including a locking movable portion 12 and a latch portion 20 is provided.

  As shown in FIGS. 1 and 2, the locking mechanism 11 locks the gate bar 7 (gate bar holding portion 18) fitted to the gate bar base portion 6 so that the gate bar 7 is fixed (non-released). Configured to maintain. Note that the locking mechanism 11 has a holding force enough to maintain the locking between the gate bar base 6 and the gate bar 7 even when a force such as vibration or wind pressure is applied due to the road opening / closing operation. That is, the fixed state is a state in which the gate bar base 6 and the gate bar 7 can be opened and closed.

  On the other hand, as shown in FIGS. 3 and 4, the locking mechanism 11 has a force greater than the holding force, for example, an external force applied when the vehicle collides with the gate bar 7, as shown in FIGS. 3 and 4. It is configured to release the locking with the part 18) and bring the gate bar 7 into a released state. The locking mechanism 11 is fitted to the gate bar base 6 by the pressing force when the gate bar 7 in the released state rotates in the direction opposite to the release direction and comes into contact with the gate bar base 6 and is pressed. The combined gate bar 7 is locked. For example, in the locking mechanism 11, the locking movable portion 12 on the gate bar base portion 6 side is pressed by the latch portion 20 on the gate bar 7 side and moves, and then the latch portion 20 is locked. Locked to the base 6.

  Further, the gate bar holding portion 18 includes a return driven portion 21 on the other end side of the release shaft 13 in the longitudinal direction. The return driven portion 21 protrudes to the rear surface side of the gate bar holding portion 18 and is provided so as to rotate integrally with the gate bar holding portion 18. The contact portion 22 (see FIG. 5 and the like) and the return driven pin 23 are connected to each other. I have.

  The contact portion 22 is an outer wall surface on one end side in the longitudinal direction (for example, the right side in the closed state of the gate bar 7), for example, a contact surface orthogonal to the longitudinal direction of the gate bar 7. When the gate bar 7 is in a fixed state, the contact portion 22 is in a free state that does not interfere with other members. Further, when the gate bar 7 is released and rotated, the contact portion 22 contacts the stopper portion 14 of the gate bar base portion 6 to limit further rotation of the gate bar 7. The release limit angle of the gate bar 7 is an angle from when the gate bar 7 is in a fixed state to when the contact portion 22 contacts the stopper portion 14, and is, for example, about 90 degrees clockwise as viewed from above.

  The return driven pin 23 is formed so as to protrude downward from the gate bar holding portion 18 in a state where the gate bar base portion 6 is lying down (see FIG. 5 and the like). The return driven pin 23 is provided on the other end side of the release shaft 13 in the longitudinal direction (for example, on the left side in the closed state of the gate bar 7) and in the vicinity of the release shaft 13, and a return drive unit 8 described later returns. The drive arm 38 is disposed on the rotation track.

  The return drive unit 8 drives the gate bar holding unit 18 (gate bar 7) to drive the gate bar base 6 around the release shaft 13, and is similar to the gate bar base 6 as shown in FIGS. It is a member formed in a long shape. FIG. 5 shows a state before the gate bar 7 is fixed and the return drive unit 8 is attached to the gate bar base 6. FIG. 6 shows the state where the gate bar 7 is in the released state and the return drive unit 8 is attached to the gate bar base 6 through the return drive unit 8.

  The return drive unit 8 mainly includes a drive mechanism unit 24 that performs return drive of the gate bar holding unit 18 (gate bar 7), and a power receiving unit 17 that supplies power to the drive mechanism unit 24. The drive mechanism unit 24 includes a return drive control unit 60 (see FIG. 11) for controlling each unit. The return drive control unit 60 will be described later.

  The drive mechanism 24 of the return drive unit 8 includes, for example, a return drive motor 26, a gear head 27, a worm gear 28, a worm gear in a substantially box-like return drive unit chassis 25 as shown in FIG. A wheel 29, a relay gear 30, a return drive gear 31, a return drive shaft 32, a sensor disk 33, an arm angle sensor 34, and a home position (HP) sensor 35 are provided. The drive mechanism 24 is positioned and fixed to the lower side (one end in the vertical direction) of the gate bar base 6 at a position where the return drive shaft 32 is coaxial with the release shaft 13 of the gate bar base 6.

  The return drive unit chassis 25 includes a chassis lower part 25a and a chassis upper part 25b, and front and rear covers (not shown). The chassis lower part 25a and the chassis upper part 25b are fastened by any means such as screwing or bonding. May be. A worm wheel support shaft 25c and a relay gear support shaft 25d projecting upward are provided on the bottom surface of the chassis lower portion 25a. A shaft hole 25e for attaching a bearing 36 for supporting the return drive shaft 32 is provided on the other end side (left side) in the longitudinal direction on each of the bottom surface of the chassis lower portion 25a and the upper surface of the chassis upper portion 25b. A shaft groove 25f for pivotally supporting the worm gear 28 is provided on a side surface (right surface) on one end side in the longitudinal direction of the chassis upper portion 25b.

  The return drive motor 26 is, for example, a DC motor, and is integrally formed with a gear head 27 having a large number of gear trains therein. A worm gear 28 is fixed to the output shaft of the gear head 27. The worm gear 28 is supported by the shaft groove 25 f of the chassis upper portion 25 b and rotates integrally with the output shaft of the gear head 27.

  The worm wheel 29 has a helical gear portion 29a meshing with the worm gear 28 and a small gear portion 29b formed below the helical gear portion 29a so as to rotate integrally, and is supported by the worm wheel support shaft 25c. The The relay gear 30 includes a large gear portion 30a that meshes with the small gear portion 29b of the worm wheel 29 and a small gear portion 30b that is formed below the large gear portion 30a so as to rotate integrally. It is pivotally supported on the shaft 25d.

  The return drive gear 31 has a gear that meshes with the small gear portion 30 b of the relay gear 30, is fixed to the return drive shaft 32, and rotates integrally with the return drive shaft 32. The return drive shaft 32 is pivotally supported by a bearing 36 attached to the shaft hole 25e. A sensor disk 33 is also fixed above the return drive gear 31 of the return drive shaft 32 so as to rotate integrally with the return drive shaft 32. An HP recess 33a for detecting the home position is formed on the outer periphery of the sensor disk 33.

  The arm angle sensor 34 and the arm HP sensor 35 are fixedly disposed around the sensor disk 33. The arm HP sensor 35 detects a predetermined position (HP recess 33a) of the sensor disk 33, thereby returning the return drive shaft. The home position of the return drive arm 38 attached to 32 is detected, and for the arm angle sensor 34, the return drive arm 38 is determined from the number of transmission / shielding pulses by slits 33 b that are opened at equal angular intervals on the peripheral surface of the sensor disk 33. The rotation angle of is detected. The rotation angle of the return drive shaft 32 and the return drive arm 38 is clockwise or counterclockwise when viewed from the gate bar base 6 side (upper side in the gate closed state or released state and right side in the return intermediate state described later). Indicates the angle.

  According to the internal structure of the drive mechanism section 24 of the return drive section 8 as described above, when the return drive motor 26 is rotationally driven, the rotational force is reduced by the gear head 27 and the output shaft is rotated to the worm gear 28. introduce. This rotational force is reduced to, for example, several tenths by meshing between the worm gear 28 and the helical gear portion 29 a of the worm wheel 29, and the small gear portion 29 b of the worm wheel 29 and the large gear portion 30 a of the relay gear 30. Is further decelerated, and the speed is also reduced by meshing between the small gear portion 30b of the relay gear 30 and the return drive gear 31, and finally the drive of the return drive motor 26 is reduced to one hundredth to return the return drive shaft. 32 is rotated. Accordingly, even with the return drive motor 26 having a relatively small diameter and small power, the return drive shaft 32 can be rotated with a strong torque by being driven to rotate at high speed and decelerating in multiple stages. Will be slow.

  Further, the upper portion of the return drive shaft 32 penetrates the shaft hole 25e of the chassis upper portion 25b and protrudes above the chassis upper portion 25b. At the upper end of the return drive shaft 32, a round convex portion 37 that is loosely fitted to the round concave portion 13a of the release shaft 13 of the gate bar base 6 is formed in a stepped shape. In other words, the round recess 13a of the release shaft 13 and the round projection 37 of the return drive shaft 32 form a positioning mechanism for the gate bar base 6 and the return drive unit 8 (drive mechanism unit 24).

  Further, a return drive arm 38 is fixed to the upper part of the return drive shaft 32 below the round convex portion 37 so as to rotate integrally with the return drive shaft 32. The return drive arm 38 is formed in a flat plate shape extending perpendicularly to the return drive shaft 32 and extends from the gate bar base 6 side to the gate bar 7.

  The length in the longitudinal direction of the return drive arm 38 is sufficiently longer than the length from the release shaft 13 coaxial with the return drive shaft 32 to the return driven pin 23 of the return driven portion 21, that is, the return drive arm 38. The return follower pin 23 of the return follower 21 is positioned on the turning track. The vertical height position of the return drive arm 38 is within the range of the protruding length of the return follower pin 23. A first pressing portion 38 a and a second pressing portion 38 b are provided at both ends in the short direction of the return drive arm 38. The first pressing portion 38a is an end portion on the clockwise direction side when the return driving portion 8 is viewed from above, and the second pressing portion 38b is an end portion on the counterclockwise direction side. Accordingly, when the return drive arm 38 rotates clockwise, the first pressing portion 38a contacts the return driven pin 23, and when the return drive arm 38 rotates counterclockwise, the second press portion 38b returns. It contacts the driven pin 23. In this way, the return drive arm 38 rotates to abut against the return driven pin 23, and by pressing the return driven pin 23 (return driven portion 21), the return driven pin 23 (return driven portion 21). The gate bar holding part 18 (gate bar 7) provided with a) can be rotated.

  As shown in FIG. 5 and the like, the circumferential position of the return drive arm 38 is maintained at a home position that does not interfere with the return driven pin 23 when the gate bar 7 is in a fixed state. The home position of the return drive arm 38 is set on the opposite side to the release direction of the gate bar 7 with respect to the return follower pin 23. As a result, when the gate bar 7 is released, the return driven pin 23 that rotates together with the gate bar 7 moves away from the return drive arm 38 at the home position and thus does not interfere.

  Next, the power feeding unit 16 and the power receiving unit 17 of the fixed non-contact power feeding mechanism 15 in the first embodiment will be described.

  The power feeding unit 16 is a power feeding antenna that is attached to the front surface of the main body housing 4 with its power feeding surface facing forward. The power feeding unit 16 is provided at a position where the power receiving surface of the power receiving unit 17 of the return driving unit 8 and the power feeding surface face each other in a state where the gate bar base 6 is lying on the side.

  The power supply unit 16 includes a power supply coil 40 including a coreless winding, and the power supply coil 40 is formed in a substantially rectangular shape wound in a direction parallel to the power supply surface. The power feeding coil 40 is housed in a power feeding housing portion 41 formed of a resin or the like as a cover.

  The power receiving unit 17 is a power receiving antenna that is attached to one end in the longitudinal direction of the gate bar base 6 with its power receiving surface facing rearward. That is, the power receiving unit 17 is attached to the drive mechanism unit 24 at a substantially symmetrical position across the horizontal rotation shaft 9. It is done. In FIG. 8 and the like, the power receiving unit 17 has the upper surface of the gate bar base 6 in the state where the gate bar base 6 is lying on the side, but the mounting position of the power receiving unit 17 is not limited to this. The power receiving unit 17 may be attached to a position outside the outer shape of the gate bar base 6 so as to face the power feeding unit 16 without being shielded by the structure of the gate bar base 6. For example, the gate bar base 6 is In this state, it may be attached to the lower surface of the gate bar base 6 or the back surface of the gate bar base 6.

  The power receiving unit 17 includes a power receiving coil 42 composed of a coreless winding, and the power receiving coil 42 is formed in a substantially rectangular shape wound in a direction parallel to the power receiving surface. The power receiving coil 42 is accommodated in a power receiving accommodating portion 43 formed of a resin or the like as a cover. The power receiving housing portion 43 also houses a charging circuit portion 63 and a battery 64 described later. The battery 64 may be detachably attached. The electrical configuration of the power receiving unit 17, the charging circuit unit 63, and the battery 64 will be described later.

  The power feeding unit 16 and the power receiving unit 17 have a slight gap between the facing exterior surfaces of the power feeding housing unit 41 and the power receiving housing unit 43, that is, between the power feeding surface of the power feeding coil 40 and the power receiving surface of the power receiving coil 42. Arranged.

  In the fixed non-contact power feeding mechanism 15 as described above, for example, when the power feeding coil 40 of the power feeding unit 16 that is the primary coil is oscillated at high frequency, the power receiving coil 42 that is the secondary coil is caused to act by the electromagnetic induction action by mutual induction. Since electromotive force is generated, power is supplied from the power supply unit 16 to the power reception unit 17. In addition, according to the coupling coefficient of the power feeding coil 40 and the power receiving coil 42, it is possible to improve power feeding efficiency by appropriately arranging capacitors in series or in parallel. Furthermore, the power feeding unit 16 and the power receiving unit 17 may be formed by winding the power feeding coil 40 and the power receiving coil 42 around a ferrite core, respectively.

  Next, an electrical configuration including the main body control unit 10 on the main body housing 4 side of the gate device 1 will be described with reference to FIG.

  The main body control unit 10 includes, for example, a CPU (Central Processing Unit), a memory, and the like, and the memory stores a control program for controlling the road opening / closing operation and the return operation of the gate device 1. In addition to the main body control unit 10, the main body housing 4 includes a gate drive motor 51, a gate angle sensor 52, a gate HP sensor 53, an external communication unit 54, a wireless communication unit 55, and a power feeding unit 16. The gate drive motor 51, the gate angle sensor 52, the gate HP sensor 53, the external communication unit 54, the wireless communication unit 55, and the power feeding unit 16 are electrically connected to the main body control unit 10 and are described above by the main body control unit 10. It is controlled based on a control program.

  The gate drive motor 51 drives the horizontal rotation shaft 9 and is, for example, a DC motor. The gate angle sensor 52 detects the rotation angle of the horizontal rotation shaft 9 and is, for example, an encoder integrated with the gate drive motor 51, and can accurately detect the rotation angle of the gate drive motor 51. Is possible. The gate HP sensor 53 detects the home positions of the gate bar base 6 and the gate bar 7 attached to the horizontal rotation shaft 9. For example, the main body control unit 10 can stop the gate drive motor 51 at a desired rotation angle based on the detection result of the gate angle sensor 52 and can perform fine angle control of the horizontal rotation shaft 9. The home position of the gate bar base 6 (gate bar 7) is a position where the longitudinal direction of the gate bar base 6 (gate bar 7) is horizontal (left-right direction).

The external communication unit 54 enables the gate device 1 (main body control unit 10) to communicate with an external device via a network. For example, a system including the gate device 1 controls the roadway separately from the gate device 1. When a road (not shown) is used to control that the roadway 2 cannot be blocked or the vehicle is approaching, the roadway control board is communicably connected via a network. For example, when the gate device 1 is installed at the ETC gate, the external communication unit 54 receives a road opening / closing operation command based on vehicle data sent from the ETC antenna to the road control panel from the road control panel. To do.
The wireless communication unit 55 wirelessly communicates with a wireless communication unit 65 of a return drive unit 8 (to be described later) between the main body control unit 10 and the return drive control unit 60 by a short-range wireless system such as Bluetooth (registered trademark). Thus, various signals such as control signals are transmitted and received wirelessly.

  Next, an electrical configuration including the return drive control unit 60 on the return drive unit 8 side of the gate device 1 will be described with reference to FIG.

  The return drive control unit 60 includes, for example, a CPU (Central Processing Unit), a memory, and the like, and is provided inside the return drive unit chassis 25. The memory of the return drive control unit 60 stores a control program for controlling the return operation of the return drive unit 8 and the like. In addition to the return drive control unit 60, the return drive unit 8 includes a return drive motor 26, an arm angle sensor 34, an arm HP sensor 35, a proximity sensor 61, a release detection switch 62, a power receiving unit 17, a charging circuit unit 63, a battery 64, and The wireless communication unit 65 is provided. The return drive motor 26, arm angle sensor 34, arm HP sensor 35, proximity sensor 61, release detection switch 62, power receiving unit 17, charging circuit unit 63, and wireless communication unit 65 are electrically connected to the return drive control unit 60. Therefore, the return drive control unit 60 is controlled based on the control program described above.

  The proximity sensor 61 is, for example, a metal sensor, is attached to the other end in the longitudinal direction of the gate bar base 6 and the rear surface, and the contact portion 22 of the return driven portion 21 contacts the stopper portion 14 of the gate bar base 6. Or it detects that approached.

  For example, the release detection switch 62 is attached to the gate bar base 6 and detects whether or not the gate bar 7 is released from the gate bar base 6.

  The power receiving unit 17 is electrically connected not only to the return drive control unit 60 but also to the charging circuit unit 63, and the battery 64 is also electrically connected to the charging circuit unit 63. When the gate bar base 6 and the gate bar 7 are in the recumbent position, the charging circuit unit 63 stores the power received by the power receiving unit 17 in the battery 64 if the gate bar 7 is in the fixed state, but the gate bar 7 is in the released state. Then, the electric power stored in the battery 64 is supplied to the return drive control unit 60. Thereby, in the return operation of the released gate bar 7, the return drive control unit 60 drives the various sensors 34, 35, 61, 62 and the return drive motor 26 of the return drive unit 8 using the power of the battery 64. Can do. Alternatively, the power reception unit 17 may directly supply the electromotive force generated in the power reception coil 41 to the return drive control unit 60 if the battery 64 is in a fully charged state.

  The wireless communication unit 65 wirelessly communicates with the wireless communication unit 55 provided in the main body casing 4 by a short-range wireless method such as Bluetooth (registered trademark), so that the main body control unit 10 and the return drive control unit 60 are connected. Various signals such as control signals are transmitted and received wirelessly.

  Next, the release operation of the gate bar 7 in the gate device 1 will be described.

  In the gate device 1, as shown in FIGS. 1, 2, 5, and the like, the gate bar base portion 6 and the gate bar 7 are normally in a fixed state, and the locking mechanism includes the locking movable portion 12 and the latch portion 20. 11 is locked. In this fixed state, the return drive arm 38 of the return drive unit 8 is maintained at the home position, and the first pressing portion 38 a of the return drive arm 38 does not contact the return driven pin 23 of the return driven unit 21. It is in a position with a slight gap.

  In the gate device 1, this fixed state is maintained in the same manner whether the gate bar 7 shown in FIG. 1 is closed or the gate bar 7 shown in FIG. 2 is opened. When the gate device 1 blocks the roadway 2, the horizontal rotation shaft 9 rotates the gate bar base 6 and the gate bar 7 to the recumbent position, thereby closing the gate bar 7 (see FIG. 1 and the like).

  Thus, when the gate bar base 6 and the gate bar 7 are in the recumbent position, the power receiving unit 17 of the return driving unit 8 faces the power feeding unit 16 of the main body housing 4. The power supply unit 16 is controlled by the main body control unit 10 and supplies a high-frequency current to the power supply coil 40 of the power supply unit 16 by, for example, a high-frequency transmission source (not shown). Then, an electromagnetic induction action due to mutual induction occurs between the power supply coil 40 that is a primary coil and the power reception coil 42 of the power reception unit 17 that is a secondary coil, and an electromotive force is generated in the power reception coil 42.

  The power receiving unit 17 supplies the electromotive force generated in the power receiving coil 42 to the charging circuit unit 63, and the charging circuit unit 63 stores the supplied power in the battery 64. The return drive control unit 60 of the return drive unit 8, the return drive motor 26, the arm angle sensor 34, the arm HP sensor 35, the proximity sensor 61, the release detection switch 62, and the wireless communication unit 65 receive power supply from the battery 64. Ready to operate.

  By the way, normally, the vehicle does not collide with the closed gate bar 7 blocking the roadway 2. However, for example, when a vehicle that has forgotten to insert an ETC card into the ETC on-board device passes through the gate of the ETC, or a vehicle that enters from the exit of the parking lot proceeds without waiting for the gate bar 7 to open intentionally or accidentally. In some cases, the vehicle may collide with the gate bar 7 blocking the roadway 2.

  For example, when the vehicle collides with the other end side of the gate bar 7 (the other end side of the gate bar main body 19), the locking mechanism 11 is unlocked by an external force applied to the other end side of the gate bar 7 due to the collision, and the gate bar base portion One end side of the gate bar 7 (one end side of the gate bar holding portion 18) is removed from one end side of the gate 6, and the gate bar 7 rotates around the release shaft 13 in the release direction (clockwise as viewed from above) (release). Operation).

  Thus, the gate bar 7 rotated by the release operation stops at various positions within the above-described range of the release limit angle. For example, the gate bar 7 may rotate about 90 degrees around the release shaft 13 and stop in the longitudinal direction substantially parallel to the roadway 2. Alternatively, when the impact force (external force) applied to the other end side is small, the gate bar 7 has a rotation angle smaller than 90 degrees, and may stop while protruding toward the roadway 2 side. Alternatively, when the gate bar 7 collides vigorously and the impact force (external force) applied to the other end side is large, when the gate bar 7 rotates 90 degrees, the contact portion 22 of the return driven portion 21 becomes the gate bar base portion 6. The stopper portion 14 is abutted vigorously and rotated in the reverse direction (counterclockwise as viewed from above) by the reaction, so that it may overhang toward the roadway 2 side and stop.

  Next, the return operation of the gate bar 7 released as described above in the gate device 1 will be described. Here, the “returning operation” is an operation of returning the gate bar 7 that has been released to a state before the releasing operation, that is, a fixed state in which the road opening and closing operation is possible.

  In the gate device 1, the gate bar 7 is fixed to the gate bar base 6 in the initial state. In order to monitor the fixed state of the gate bar base 6 and the gate bar 7, the return drive control unit 60 of the return drive unit 8 determines whether or not the gate bar 7 is released from the gate bar base 6 by the release detection switch 62. Is always detected. As described above, when the gate bar 7 is released from the gate bar base 6, the release detection switch 62 is turned on.

  When the release detection switch 62 is turned on, the return drive control unit 60 of the return drive unit 8 controls the return drive motor 26 to perform reverse drive. Then, the rotational force of the return drive motor 26 is transmitted to the return drive shaft 32 via the gears 28, 29, 30 and 31 of the return drive unit 8, and the return drive shaft 32 is rotated to return the return drive arm 38. The follower pin 21 of the follower 21 is rotated in a direction following the return follower pin 23 (release direction, clockwise as viewed from above). At this time, the first pressing portion 38a of the return drive arm 38 presses the return driven pin 23 of the return driven portion 21 when the gate bar 7 projects to the roadway 2 side, and the gate bar 7 (gate bar holding portion). 18) is rotated with respect to the gate bar base 6 in the release direction (clockwise as viewed from above).

  The rotation angle of the return drive arm 38 is sequentially detected by the arm angle sensor 34, and the detection result of the arm angle sensor 34 is input to the return drive control unit 60 of the return drive unit 8, that is, the return drive control unit. Reference numeral 60 monitors the rotation angle of the return drive arm 38. When the arm angle sensor 34 detects a predetermined angle α1 set in advance in the return drive control unit 60, the return drive control unit 60 stops driving the return drive motor 26 and rotates the return drive arm 38. Stop. The predetermined angle α1 is, for example, an angle (90 degrees plus alpha) obtained by adding a release limit angle (for example, 90 degrees) of the gate bar 7 to a gap angle between the return drive arm 38 and the return drive pin 32 in the fixed state. .

  In this way, the gate bar 7 (gate bar holding portion 18) is opened by a release limit angle (90 degrees) with respect to the gate bar base portion 6, and the stopped return drive arm 38 supports the return drive pin 23. This state is maintained. Further, when the gate bar 7 reaches the release limit angle, the contact portion 22 of the return driven portion 21 contacts the stopper portion 14 of the gate bar base portion 6. Such contact between the contact portion 22 and the stopper portion 14 is detected by the proximity sensor 61.

  When the proximity sensor 61 detects the contact between the contact portion 22 and the stopper portion 14, the return drive control unit 60 determines that the release is completed, and determines the determination result via the wireless communication unit 65 of the return drive unit 8. Then, the data is transmitted to the wireless communication unit 55 of the main body housing 4 and further transmitted to the main body control unit 10. The return drive control unit 60 may omit the detection by the proximity sensor 61 and determine the release completion state by detecting the angle α1 of the arm angle sensor 34 described above. The main body control unit 10 drives the gate drive motor 51 to rotate forward according to the determination result of the release completion state, and the horizontal rotation shaft 9 together with the gate bar base portion 6 and the gate bar 7 is low-speed clockwise when viewed from the front. Rotate. Thereby, the gate bar 7 is gradually raised toward the upper side of the main body housing 2 while being held in the release completion state with respect to the gate bar base portion 6. In this way, the gate bar 7 shifts to the return intermediate state arranged above the main body housing 2 while being in the release completed state.

  The rotation angle of the horizontal rotation shaft 9 is detected by the gate angle sensor 52, and the detection result of the gate angle sensor 52 is input to the main body control unit 10, and the main body control unit 10 rotates the rotation of the horizontal rotation shaft 9. The movement angle is monitored. When the gate angle sensor 52 detects a predetermined angle β1 set in the main body control unit 10 in advance, specifically, the same angle β1 (for example, 90 degrees) as the open state of the gate bar 7, the main body control unit 10 Stops driving the gate drive motor 51 and stops the rotation of the horizontal rotation shaft 9. This state is a return intermediate state (see FIG. 4). Thus, when the gate bar base 6 and the gate bar 7 are rotated around the horizontal rotation shaft 9, the gate bar 7 is always in a release completed state, so that the other end in the longitudinal direction of the gate bar main body 19 projects toward the roadway 2 side. Therefore, the transition to the return intermediate state of the gate bar 7 can be performed stably.

  When the main body control unit 10 determines the transition of the gate bar 7 to the return intermediate state as described above, the determination result is sent to the wireless communication unit 65 of the return drive unit 8 via the wireless communication unit 55 of the main body housing 4. And then to the return drive control unit 60. The return drive control unit 60 rotates the return drive shaft 32 by rotating the return drive motor 26 in the normal direction according to the determination result of the return intermediate state, thereby rotating the return drive arm 38 in the direction opposite to the release direction ( Rotate counterclockwise when viewed from the right. Accordingly, the second pressing portion 38b of the return drive arm 38 presses the return driven pin 23 against the gate bar 7 in the released state, and the gate bar 7 (gate bar holding portion 18) is released in the release direction with respect to the gate bar base portion 6. Rotate in the opposite direction (counterclockwise when viewed from the right). The pressing force in the direction opposite to the release direction acts on the locking mechanism 11 such as the locking movable portion 12 and the latch portion 20 provided on one end side of the gate bar base portion 6 and one end side of the gate bar 7, The gate bar base 6 and the gate bar 7 are securely locked by the locking mechanism 11. Thereby, the gate bar 7 will be in a fixed state (non-release state).

  The rotation angle of the return drive arm 38 is sequentially detected by the arm angle sensor 34 as described above, and the return drive control unit 60 monitors the rotation angle of the return drive arm 38. When the arm angle sensor 34 detects a predetermined angle α2 set in the return drive control unit 60 in advance, the return drive control unit 60 stops driving the return drive motor 26 and rotates the return drive arm 38. Stop. The predetermined angle α2 is, for example, a counterclockwise rotation angle of the return driving arm 38, and the second pressing portion 38b contacts the return driven pin 23 from the state where the first pressing portion 38a contacts the return driven pin 23. This is an angle obtained by adding a return operation angle of the gate bar 7 (equal to a release limit angle, for example, 90 degrees) to an angle until contact (360 degrees or less).

  Thus, the gate bar 7 (gate bar holding part 18) and the gate bar base part 6 which are in a fixed state are in a state of being arranged in the standing position (see FIG. 2). In this state, the release detection switch 62 is turned off.

  When the release detection switch 62 is turned OFF, the return drive control unit 60 rotates the return drive shaft 32 by rotating the return drive motor 26 in the reverse direction, thereby rotating the return drive arm 38 in the release direction (clockwise as viewed from the right). Rotate around).

  At this time, the return drive arm 38 is sequentially detected by the arm HP sensor 35, and the detection result of the arm HP sensor 35 is input to the return drive control unit 60. The return drive control unit 60 is configured so that the return drive arm 38 is in the home position. I'm watching you return.

  The arm HP sensor 35 is turned ON when detecting the HP recess 33a of the sensor disk indicating that the return drive arm 38 has returned to the home position, and the return drive control unit 60 is driven to return when the arm HP sensor 35 is turned ON. The drive of the motor 26 is stopped and the rotation of the return drive arm 38 is stopped. Then, the return drive control unit 60 transmits a notification of the end of the operation on the return drive unit 8 side to the wireless communication unit 55 of the main body housing 4 via the wireless communication unit 65 of the return drive unit 8. It is transmitted to the control unit 10.

  By the way, the main body control unit 10 determines whether or not the roadway 2 can be blocked by the gate bar 7. For example, when the main body control unit 10 receives a signal indicating that the vehicle cannot be blocked from the roadway control panel as described above or the vehicle is approaching via the external communication unit 54, the body control unit 10 determines that the roadway 2 cannot be blocked, When such a signal is not received, it is determined that the signal can be blocked.

  When the main body control unit 10 receives the notification of the end of the operation on the return drive unit 8 side as described above and determines that the roadway 2 can be shut off, the main body control unit 10 drives the gate drive motor 51 in the reverse direction to drive the horizontal rotation shaft 9. Together with the gate bar base 6 and the gate bar 7 are rotated counterclockwise as viewed from the front. Thereby, the gate bar 7 gradually descends toward the left of the main body housing 2 from the state in which the gate bar 7 is disposed in the standing position, and the gate bar base portion 6 and the gate bar 7 move to the recumbent position and are closed ( (See FIG. 1).

  When the gate bar base 6 and the gate bar 7 reach the recumbent position, the gate HP sensor 53 is turned on. When the gate HP sensor 53 is turned on, the main body control unit 10 stops driving the gate drive motor 51 and stops the rotation of the horizontal rotation shaft 9. Thereby, the return operation is completed.

  In the first embodiment described above, the gate bar 7 is rotated with respect to the gate bar base 6, and the return drive unit 8 having the return drive arm 38 is provided on the gate bar base 6 side, and the return driven pin is provided on the gate bar 7 side. Although the structure provided with the return driven part 21 which has 23 was demonstrated, another structure may be sufficient.

  In the first embodiment described above, the locking mechanism 11 including the locking movable portion 12 and the latch portion 20 has been described as the locking mechanism 11 that locks the gate bar base 6 and the gate bar 7. The locking mechanism 11 is not limited to such a configuration, and may have another configuration as long as the gate bar base 6 and the gate bar 7 can be locked with a predetermined holding force.

  In the first embodiment described above, as a positioning mechanism for the gate bar base 6 and the return drive unit 8, the return drive shaft 32 of the return drive unit 8 is positioned relative to the circular recess 13 a of the release shaft 13 of the gate bar base 6. Although the structure which the round convex part 37 fits loosely was demonstrated, it is not limited to this structure. The return drive unit 8 may not include the above positioning mechanism as long as the gate bar 7 can be rotated with respect to the gate bar base 6 by the return drive arm 38.

  According to the first embodiment, as described above, the gate device 1 that restricts the passage of the vehicle (moving body) on the roadway 2 includes the main body housing 4 (main body portion), the horizontal rotation shaft 9, and the like. The gate bar base 6, the gate bar 7, and the return drive unit 8 are provided. The horizontal rotation shaft 9 is attached to the main body housing 4 so as to protrude on the opposite side to the vehicle traveling direction (moving body traveling direction) parallel to the roadway 2. The gate bar base portion 6 is formed in an elongated shape, and is attached to the horizontal rotation shaft 9 so that the longitudinal direction thereof is orthogonal to the horizontal rotation shaft 9. When opening the door, it is rotated by the horizontal rotation shaft 9 so as to stand up. The gate bar 7 is formed in an elongated shape, and is attached to the gate bar base portion 6 so that one end side in the longitudinal direction is pivotally supported by the gate bar base portion 6 and is rotatable in the release direction toward the vehicle traveling direction and the reverse direction thereof. The gate bar base 6 is detachably provided on the gate bar base 6 so as to be fixed and integrated with the gate bar base 6 so as to be released from being fixed with the gate bar base 6 by receiving a predetermined external force. The return drive unit 8 is positioned and fixed (attached) to the gate bar base 6 side, and includes a return drive arm 38 that rotates the gate bar 7 in the release direction and in the opposite direction. Then, when the gate bar 7 is in the release state, the return operation of the gate bar 7 is started. In the return operation, the release drive arm 38 rotates the gate bar 7 in the release direction and retreats from the roadway 2. The horizontal rotation shaft 9 is rotated in the direction in which the gate bar base 6 is raised while the gate bar 7 is held in the release completed state by the return drive arm 38, and the return drive arm 38 in the state where the gate bar base 6 is raised. Performs a fixed state return operation in which the gate bar 7 is rotated in the direction opposite to the release direction to shift to the fixed state.

  In particular, according to the first embodiment, the return drive unit 8 is configured to operate with drive power supplied from the main body housing 4 by non-contact power feeding. As a result, the return drive unit 8 can be supplied with electric power by non-contact power supply and perform the return operation of the gate bar 7, so that the return drive attached to the gate bar base 6 that operates at high speed during the normal opening and closing operation of the gate bar 7. It is no longer necessary to route the power supply wiring between the unit 8 and the main body control unit 10 on the main body housing 4 side, the problem of the durability of the power supply wiring is solved, and the durability of the operation of the gate device 1 is maintained for a long time. can do.

  In the gate device 1 according to the first embodiment, the return drive unit 8 includes the power receiving unit 17 attached to the gate bar base 6, and the main body housing 4 is connected to the power receiving unit 17 in a state where the gate bar base 6 is lying on the side. The power supply unit 16 is provided at a position that coincides with the face-to-face, and the power reception unit 17 is configured to receive power supply from the power supply unit 16 by fixed non-contact power supply. Thereby, since it is only necessary to arrange the power receiving unit 17 and the power feeding unit 17 each having the same position only when the gate bar base 6 is in a lying state, it is possible to suppress the component cost for non-contact power feeding, The overall cost can be kept low.

  In addition, the gate device 1 according to the present embodiment is configured such that the return drive unit 8 includes a battery 64 that charges the power supplied via the power receiving unit 17. As a result, not only the return drive operation of the gate bar 7 by the return drive unit 8, but also the arm angle sensor 34, the arm HP sensor 35, the proximity sensor 61, the release detection switch 62, etc. provided on the return drive unit 8 side (gate bar base 6 side) These various sensors and other components can be operated with electric power stored in the battery 64. Further, since the return drive control unit 60 can be arranged in the return drive unit 8 and can be operated with the electric power stored in the battery 64, the return drive control unit 60 separates the return drive unit 8 from the main body housing 4 side. It is possible to finely control the drive mechanism 24 and the various sensors 34, 35, 61, 62 and other components.

  Furthermore, in the gate device 1 according to the present embodiment, the power receiving unit 17 and the battery 64 are attached to the drive mechanism unit 24 of the return drive unit 8 that drives the gate bar 7 at a substantially symmetrical position across the horizontal rotation shaft 9. Configured as follows. As a result, the power receiving unit 17 and the battery 64 serve as counterweights for the drive mechanism unit 24, and in particular, since the relatively heavy battery 64 can be used as the counterweight, the main body control unit 10 drives the gate drive motor 51. Thus, it is possible to suppress power consumption when the horizontal rotation shaft 9 is rotated together with the gate bar base 6 and the gate bar 7.

  Furthermore, the gate device 1 of the present embodiment is configured such that the main body housing 4 and the return drive unit 8 include wireless communication units 55 and 65 that perform wireless communication with each other. Thereby, not only the power supply to the return drive unit 8 but also the signal communication between the main body housing 4 and the return drive unit 8 can be performed wirelessly, so that the electricity associated with the rotation of the gate bar base 6 and the gate bar 7 can be achieved. The concern about the durability of the wiring is eliminated.

  Further, since the main body control unit 10 grasps the rotation positions such as the standing position and the recumbent position of the gate bar base 6 and the gate bar 7 by the gate angle sensor 52, the power supply operation of the power supply unit 16 is performed in the recumbent state. If it is not in the lying state, power consumption can be reduced by controlling the power feeding operation of the power feeding unit 16 to stop.

Even at the position, the power receiving unit 72 is provided so as to face each other. For example, the power feeding unit 71 includes a power feeding core 73 such as a ferrite core that is curved in a substantially circular shape and has a U-shaped cross section, and an outer periphery of a convex portion that forms a U-shape of the power feeding core 73. The feeding coil 74 is formed by being wound along an arc shape.

  The power supply core 73 and the power supply coil 74 of the power supply unit 71 are accommodated in a power supply accommodation unit 75 formed of a resin or the like as a cover, and the power supply unit 71 has a U-shaped convex portion of the power supply core 73. It is attached to the front surface of the main body housing 4 along the turning locus of the power receiving unit 72 toward the front. For example, the power feeding unit 71 may be disposed so as to be fitted into an opening having the same shape provided on the front surface of the main body housing 4 so that the power feeding surface is exposed from the opening. Alternatively, the power feeding unit 71 may be attached to the outside of the main body housing 4 and arranged so that only the wiring from the power feeding coil 74 is provided inside the main body housing 4. Further, when the main body housing 4 is made of metal, the main body housing 4 acts as a yoke plate with respect to the power feeding coil 74, so that power feeding efficiency can be improved.

  The power receiving unit 72 houses the power receiving core 76 and the power receiving coil 77 in the power receiving housing portion 78, has a curved shape similar to that of the power feeding portion 71, and has an arc length of about one-third that of the power feeding portion 71. A power receiving transformer to be formed. The power receiving unit 72 is attached to the upper surface of the gate bar base 6 in a state in which the gate bar base 6 is lying on its back with the U-shaped convex portion of the power receiving core 76 facing backward. Note that the mounting position of the power receiving unit 72 is not limited to this, and the power receiving unit 72 is outside the outer shape of the gate bar base 6 and can be opposed to the power feeding unit 71 without being shielded by the structure of the gate bar base 6. For example, it may be attached to the lower surface of the gate bar base portion 6 or the back surface of the gate bar base portion 6 in a state where the gate bar base portion 6 is lying down.

  The return drive unit 8 of the second embodiment includes a power supply circuit unit 79 instead of the charging circuit unit 63 of the first embodiment. The power supply circuit unit 79 is configured to supply the electromotive force generated in the power receiving coil 77 directly to the return drive control unit 60.

  As described above, the power feeding unit 71 and the power receiving unit 72 always face each other regardless of the position of the power receiving unit 72 in the locus where the power receiving unit 72 rotates 90 degrees, and the convex portion of the power feeding core 73 And the convex portion of the power receiving core 76 are always arranged to face each other. Note that FIG. 16 shows a state where the power receiving unit 72 is at an intermediate position of movement. A gap is provided between the convex portion of the power feeding core 73 and the convex portion of the power receiving core 76, and the facing exterior surfaces of the power feeding housing portion 75 and the power receiving housing portion 78 are slightly separated from each other.

  Furthermore, the power feeding unit 71 and the power receiving unit 72 each include a communication unit, and each communication unit provides a separate wireless communication device by superimposing communication data on a high frequency oscillation carrier wave for power feeding. Instead, various signals such as control signals are communicated between the main body housing 4 side (main body control unit 10) and the return drive unit 8 side (return drive control unit 60).

  Each communication unit of the power supply unit 71 and the power reception unit 72 may perform high-frequency oscillation for power supply and oscillation for communication in a time-sharing manner, thereby providing a separate wireless communication device, Various signals such as control signals can be communicated between the main housing 4 side (main body control unit 10) and the return drive unit 8 side (return drive control unit 60). In addition, when the signal is transmitted from the return drive unit 8 to the main body housing 4 side, the power receiving core 77 may be oscillated from the communication unit side of the power receiving unit 72 with a small amount of power stored separately in a capacitor or the like.

  In the second embodiment, a release detection switch 80 is provided on the body housing 4 side instead of the release detection switch 62 provided on the return drive unit 8 side. For example, the release detection switch 80 is configured by a reflective distance measuring sensor. In this case, a through hole 81 that is linearly connected in the front-rear direction is provided in the gate angle sensor 52 that is an encoder, the central portion of the gate drive motor 51 and the horizontal rotation shaft 9, and the corresponding portion in the gate bar base 6. The release detection switch 80, which is a reflective distance measuring sensor, is disposed behind the gate angle sensor 52, emits detection light forward through each through hole 81, and receives reflected light from the front. To measure the distance. If the gate bar 7 (gate bar holding portion 18) is integrally fixed to the gate bar base portion 6, the distance to the back surface of the gate bar holding portion 18 measured by the release detection switch 80 is constant, so that the gate bar 7 is fixed. Can be detected. On the other hand, when the integrated fixing of the gate bar base portion 6 and the gate bar 7 (gate bar holding portion 18) is released, the distance to the back surface of the gate bar holding portion 18 measured by the release detection switch 80 changes, so that it is in the released state. Can be detected.

  Note that the release detection switch 80 may be constituted by a mechanical actuator instead of the reflective distance measuring sensor.

  The main body control unit 10 monitors the detection result of the release detection switch 80, and starts or stops the power supply operation by the power supply unit 71 according to the detection result, thereby saving power compared to the case of always supplying power. Can be achieved. For example, the main body control unit 10 controls to stop the power supply operation of the power supply unit 71 when the gate bar 7 is maintained in a fixed state, and to perform the power supply operation of the power supply unit 71 when the gate bar 7 shifts to the release state. To do. That is, the main body control unit 10 starts the power feeding operation of the power feeding unit 71 from the timing when the release detection switch 80 is turned on (timing when the release state is detected), and after the returning operation of the gate bar 7 is completed, the power feeding unit 71. The power feeding operation is stopped.

  According to the second embodiment, as described above, the gate device 1 has the same configuration as that of the first embodiment, and the power feeding unit 71 is in a state in which the gate bar base 6 is in a lying state and in a standing state. Is formed in an arc shape along the rotation trajectory of the power receiving unit 72 in the movement stroke between the power receiving unit 72 and the power receiving unit 72 is provided so as to face the power receiving unit 72 at any position. The power supply unit 71 is configured to receive power supply.

  As described above, in the gate device 1 according to the second embodiment, the movable non-contact power feeding mechanism 70 including the power feeding unit 71 and the power receiving unit 72 is used regardless of the rotation phase of the power receiving unit 72, that is, the gate bar. Power is supplied from the power supply unit 71 to the power reception unit 72 regardless of whether the base 6 and the gate bar 7 are in the lying state, standing state, or in the middle of the state, and the return drive unit 8 is supplied via the power supply circuit unit 79. Power is always supplied to Thereby, the drive operation and signal communication of the return drive part 8 can be performed stably, without providing a battery. In particular, the gate bar base 6 is adjusted while the return drive arm 38 and the horizontal rotation shaft 9 are synchronously controlled so that the rotation trajectory of the other end in the longitudinal direction of the gate bar 7 does not protrude toward the roadway 2 side. The return drive operation for shifting from the lying state to the standing state can be easily realized even in the non-contact power supply state.

  Therefore, in the gate device 1 according to the second embodiment, it is not necessary to mount a heavy battery, the facility can be simplified and the cost can be reduced, and the return operation of the gate bar 7 from the released state can be achieved.

For example, the power supply coils 40 and 74 and the power reception coils 42 and 77 may be coated with a resin paint. In that case, the gap can be set as narrow as possible because the resin cover is unnecessary.

  In the first and second embodiments described above, different configurations have been described in other parts than the fixed non-contact power feeding mechanism 15 and the movable non-contact power feeding mechanism 70.
