Description

The present invention relates to an upper and lower two-level bicycle parking facility.

For example, as shown in Patent Literature 1, a plurality of slide racks are placed on a fixed rail arranged on the ground surface in a crossing manner and can slide on the fixed rail, and a plurality of slide racks are installed on the ground surface at regular intervals. Each post has a lifting rack that can be moved up and down by a motor drive, and the lifting rack is mounted on the upper and lower stages in the empty space created by sliding the slide rack located on the lower stage. A two-level bicycle parking facility is widely known that can be moved up and down between.

In Patent Documents 1, 2, and 3, a sensor for directly detecting contact with an obstacle (slide rack, bicycle, worker, etc.) is provided on the bottom side of the lifting rack, and the sensor detects the obstacle while the lifting rack is descending. to avoid damage (including injury) by stopping or reversing the motor (switching up) when it comes into contact with the

By the way, if you focus on the lifting rack that is descending from the upper stage and the multiple slide racks located on the lower stage, you can see the relative positional relationship between the two in a plan view, whether or not a bicycle is mounted, and the size of the mounted bicycle (especially the width of the handlebar). The contactable area is diverse and changes from moment to moment. Therefore, it is difficult to ensure safety in a wide range by sensors provided on the bottom side of the lifting rack as in Patent Documents 1, 2, and 3.

Moreover, since the sensor directly senses contact with an obstacle to stop the descent of the lifting rack or to reverse and lift the lifting rack, there is a possibility of causing a delay in avoiding danger. When the normal lifting speed is slowed so as not to cause an avoidance delay, there is a concern that work efficiency will deteriorate. Moreover, since the sensor is provided on the moving lifting rack, the detection range of the sensor constantly fluctuates as the lifting rack moves up and down, and the detection range itself may become unstable. Furthermore, although the frequency of occurrence is low, danger cannot be avoided even if the sensor comes into contact with an obstacle while the lift rack is ascending.

On the other hand, Patent Documents 3, 4, and 5 disclose indirectly detecting contact between the lifting rack and an obstacle by detecting motor load, wire slackness, chain slackness, etc., and stopping the descent or reversing the lifting rack. Techniques for doing so are disclosed. However, when using these indirect sensing means, danger avoidance may be delayed more than direct sensing. In addition, phenomena such as motor load, wire slackness, and chain slackness can be caused by causes other than contact with obstacles, and may result in erroneous detection or malfunction.

In addition, Patent Document 3 also describes providing a motion sensor on the ceiling surface of the bicycle parking lot, but the obstacle is hidden behind the elevating rack, the slide rack, and the bicycle etc. mounted on them and is accurately detected. Moreover, it is difficult to install in an outdoor bicycle parking lot, and there are many problems in ensuring safety.

JP 2019-34704 A Japanese Patent No. 6670336 JP 2018-141298 A Japanese Patent No. 4133300 JP-A-2001-279944

An object of the present invention is to ensure the safety of bicycle parking work by stopping the driving of the lifting drive means before contact between the lifting rack and an obstacle (especially the slide rack and the mounted bicycle) occurs. To provide a stepped bicycle parking facility .

Means for solving the problem and effects of the invention

In order to solve the above problems, the upper and lower two-level bicycle parking facility of the present invention is

Elevation drive means (for example, drive source and transmission) that are provided for each elevating rack and individually generate driving force (based on electromotive force, fluid pressure, etc.) for vertically elevating the elevating rack along the corresponding support column mechanism); and
Control means (such as an electric signal system, a fluid pressure signal system, etc.) for individually controlling the vertical movement of the lifting rack by the lifting drive means;
For each of the lifting racks, a security area is set which has a width in the horizontal direction from the supporting column on which the lifting rack is supported to at least the adjacent supporting column in a plan view, and which extends from the fixed rail in one longitudinal direction. a detection means arranged on a reference plane in and individually detecting the presence of the slide rack in each of the security areas;
The control means drives the lifting rack corresponding to the detection means regardless of whether or not a bicycle is mounted when any of the detection means detects the presence of the slide rack within the corresponding caution area. It is characterized by always outputting a driving stop command to the lifting/lowering driving means.

In this manner, the warning area is fixedly formed on the reference plane by the detection means arranged on the reference plane, and the existence or non-existence of the slide rack in the warning area is detected before the lifting rack is driven up and down. It is possible to stop the driving of the lifting and lowering driving means before contact with an object (especially the slide rack and the mounted bicycle) occurs, so that the bicycle parking work can be performed safely and quickly.

Moreover, regardless of whether the lifting rack is being lowered or raised, and regardless of whether the bicycle is mounted or not, the warning area is stably provided within a predetermined range depicted in a plan view. It is possible to easily avoid the danger of contacting an obstacle while the lifting rack is moving up and down.

Regarding the slide rack, there is a type that is slidably mounted on a single fixed rail arranged in the horizontal direction, and a type that is slidably mounted across a pair of fixed rails arranged in the horizontal direction. including type. In addition, there is a type in which the elevating rack protrudes only to the left or right from each pillar in plan view with respect to the arrangement direction (horizontal direction) of the pillars, and a type in which the elevating racks protrude alternately to the left and right in plan view from each pillar. including. Further, the drive source of the lifting drive means includes an electric motor, a hydraulic/pneumatic cylinder, etc., and the detection means may be of a contact type or a non-contact type (optical, ultrasonic, electromagnetic wave, etc.). is included.

Each of the elevating racks protrudes in the same longitudinal direction from the laterally aligned columns,
The caution areas are set in a form that overlaps each other in a plan view between adjacent struts.

In this way, by partially overlapping the warning areas, the safety of the lifting rack against obstacles during vertical movement is further increased, and more lifting racks and slide racks are installed in the bicycle parking facility ( containment).

Each of the lifting racks has display means (for example, a blue lamp) for displaying whether or not the corresponding lifting drive means can be driven based on the operator's operation, and the display means indicates whether the lifting drive means can be driven. An operation means (for example, a lowering side push button switch or a raising side foot switch) that can be operated (lower or higher) by the operator when displaying (for example, lighting) is further provided,
The control means are
When outputting a drive stop command to the lifting/lowering drive means, the corresponding display means displays (for example, turns off) that the operator cannot operate (for example, lowering), and the corresponding operation means is disabled (for example, push button switch is turned off). while
When the detection means detects the absence of the slide rack, the corresponding display means indicates (for example, turns on) that the operator can operate (for example, lowering).

In this way, when a slide rack is present in any caution area, the corresponding operating means is rendered inoperable, and when the slide rack is absent, the corresponding display means indicates that the operation is possible, thus ensuring the safety of manual operation. can increase

The detection means includes a rod-shaped or plate-shaped detection member (e.g., zone sensor) arranged on the reference plane in parallel with the fixed rail over the entire lateral width of the caution area in plan view,
The presence or absence of the slide rack is detected by contact with the detection member.

With such a contact-type detection member, the presence or absence of the slide rack can be reliably detected.

The detection member supports the horizontal slide of the slide rack together with the fixed rail from below, and detects the presence or absence (irrespective of whether or not the bicycle is mounted) by vertical movement accompanying passage of the slide rack.

In this manner, the presence or absence of the slide rack can be reliably detected by the detection member that detects the vertical movement due to the load.

Further comprising a biasing means (e.g., gas spring, constant load spring, weight, etc.) for biasing the lifting rack in a direction in which the lifting rack is always lifted to assist the driving force of the lifting drive means,
The lifting drive means includes an electric motor as a drive source and a chain transmission mechanism driven by the electric motor. a link chain that is internally wound around these sprocket wheels and that has both ends connected to the lifting rack;
The biasing means includes two moving pulleys having a common rotation axis and connected to the tip of a piston rod projecting downward from a cylinder of a gas spring having a base end attached to the inside of the upper part of the column to exert traction force. , two fixed pulleys fixed inside the column at a position higher than the cylinder, and a single wire rope wound alternately around each movable pulley and each fixed pulley.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings.

The upper and lower two-level bicycle parking facility 1000 of this embodiment has a plurality of slide racks 200 and lifting racks 100, as shown in FIGS.

The racks 100 and 200 here have a longitudinal shape whose longitudinal direction X is the forward/rearward direction (forward/backward direction) when loading and unloading the bicycle BCL, and extend in a cantilever shape with an open upper surface. An entrance 4 for loading and unloading the bicycle BCL is formed at the front end (rear end) of the racks 100 and 200 . The racks 100 and 200 here are provided with a pair of braces 5 (side guards) on both sides in the width direction for preventing the mounted bicycle BCL from overturning. Further, the rack 100 is provided on the front side with a tire guard 6 that holds a preceding carry-in wheel (for example, a front wheel) of the mounted bicycle BCL.

Each slide rack 200, as shown in FIGS. 1 and 2, is a single or parallel slide rack arranged linearly along the lateral direction Y (see FIG. 2) set on the ground surface E (reference plane). It is placed in a longitudinal direction X that intersects perpendicularly or obliquely with respect to a plurality of fixed rails 2 in a plan view, and is slidable on the fixed rails 2 . Each slide rack 200 has a length corresponding to one bicycle in its own longitudinal direction X, allows the bicycle BCL to be taken in and out from one side in the longitudinal direction X, and is irrespective of whether or not the bicycle BCL is mounted. It is slidable in the horizontal direction Y on the top.

Each slide rack 200 here has a plurality of rollers 8 (rolling elements) attached to the bottom surface side of one end (here, the front end), and through the plurality of rollers 8 (rolling elements), to the ground surface E. It is constructed as a horizontal slide movable type that can move in the horizontal direction along the installed fixed rail 2. - 特許庁In addition, casters 9 are attached to the bottom side of the other end (here, the rear end) of each slide rack 200, and the casters 9 land on the ground surface E (reference plane) to move the racks 200. It is configured to support and roll in the horizontal direction Y at that time. With these configurations, each slide rack 200 is slidable in the horizontal direction Y. As shown in FIG.

As shown in FIGS. 1 and 3, the elevating rack 100 is cantilevered for each support 1 erected at a constant pitch from the ground surface E (reference plane) along the lateral direction Y (see FIG. 3). It is supported by protruding in the longitudinal direction X, and can be raised and lowered along the column 1 . Specifically, as shown in FIG. 2, each elevating rack 100 has an upper stage (predetermined It is possible to move up and down between the upper stage position) and the lower stage (predetermined lower stage position). In addition, each lifting rack 100 is supported by projecting in a cantilevered manner in the longitudinal direction X by a length corresponding to one bicycle BCL, and the bicycle BCL is supported from one side in the longitudinal direction X at the lower position. It can be put in and taken out and can be moved up and down along the column 1 regardless of whether or not the bicycle BCL is mounted.

In addition, as shown in FIGS. 1 and 4 to 7, the upper and lower two-level bicycle parking facility 1000 is provided for each lifting rack 100, and is used to move the lifting rack 100 up and down along the corresponding pillar 1. Elevation driving means 110 for individually generating driving forces based on electromotive force, fluid pressure, etc. (here, electromotive force); and a control means 500 (see FIG. 16) for a pressure signal system or the like (here, an electrical signal system). The control means 500 here has, as shown in FIG. 16, an individual control section 502 corresponding to each column 1 and lifting rack 100, and a main control section 501 to which they are connected. Further, the individual control unit 502 includes a detection unit 3 (detection unit 34), a detection unit 150 (detection unit 154), an illumination type push button 160, limit switches 171 and 172, an electric motor 111, and a detection unit 3 (detection unit 34), which will be described later, related to the corresponding lifting rack 100. etc. connect. The control units 501 and 502 are well-known microcomputers having CPUs and the like, and various programs for individually controlling the vertical movement of the lifting rack 100 by the lifting drive means 110 are stored in predetermined storage units. , they are executable by the CPU.

1 and 4 to 7, the upper and lower two-level bicycle parking facility 1000 here always biases each lifting rack 100 in the upward direction to generate the driving force of the lifting drive means 110. A biasing means 120 is provided to assist.

The elevation drive means 110 includes an electric motor 111 as a drive source, as shown in FIG. The driving force of the electric motor 111 is smaller than the actual vehicle weight of the lifting rack when the bicycle BCL is mounted, and the upward biasing force of the biasing means 120 is greater than the empty lifting rack weight when the bicycle BCL is not mounted. Large. Here, the weight of the lifting rack 100 is assumed to be 10 kg, and the maximum weight of the bicycle BCL is assumed to be 40 kg. exerts a constant upward biasing force capable of towing the half of the total weight of 25 kg, and the lifting drive means 110 exerts a constant upward driving force (motor torque: 10.6 Nm) capable of pulling the remaining half of the weight of 25 kg. These constant upward biasing force and constant upward driving force are exerted when the lifting rack 100 is lifted regardless of whether the bicycle BCL is mounted on the lifting rack 100 or not. When the lifting rack 100 is lowered, while the constant upward biasing force of the biasing means 120 is always exerted, the lifting drive means 110 exerts a constant downward driving force exceeding the constant upward driving force, and the actual vehicle state of the lifting rack 100 and the idle state of the lifting rack 100 are controlled. Works regardless of the situation. When the lifting rack 100 is stopped, the electric motor 111 stops driving, and the worm gear 116 connected to the electric motor 111 is self-locked to stop and hold the lifting rack 100 .

The electric motor 111 can also have a regenerative braking function corresponding to the torque corresponding to the upward biasing force of the biasing means 120 exceeding the empty weight of the lifting rack 100 when the lifting rack 100 is lifted in an empty state. However, in that case, it is necessary to change some configurations.

The lifting drive means 110 includes a chain transmission mechanism 112 driven by an electric motor 111, as shown in FIG. As shown in FIG. 5, the chain transmission mechanism 112 includes sprocket wheels 113 and 114 pivotally supported in the upper and lower interiors of the strut 1, respectively, and is wound around the sprocket wheels 113 and 114 inside the strut 1. and a link chain 115 having both ends connected to the lifting rack 100 . The electric motor 111 rotates the upper sprocket wheel 113 via the worm gear 116 . Here, as shown in FIG. 5, an elevating carriage 105 that ascends and descends along the column 1 is provided at the front end of the elevating rack 100, and one end 115A of the link chain 115 is positioned above the elevating carriage 105 (on the side of the sprocket wheel 113). ), and the other end 115B is connected to the lift carriage 105 from the lower side (sprocket wheel 114 side). A roller 105R (see FIG. 5) that rolls on a guide rail 15G (see FIG. 7B) extending in the vertical direction Z provided on the rear side surface of the support column 1 is assembled to the elevator carriage 105. As shown in FIG.

As shown in FIGS. 4 and 5, the biasing means 120 has a gas spring 121 here as an upward biasing force source. The urging means 120 also has a rope transmission mechanism 122 that transmits an upward urging force to the corresponding lifting rack 100 .

As shown in FIG. 5, the gas spring 121 here, which biases the lifting rack 100 (lifting cart 105) so as to always pull it upward, includes a cylinder 121S having a base end attached inside the upper part of the column 1, and a piston rod 121P projecting downward from the cylinder 121S to exert a traction force. As shown in FIG. 6, an assembly shaft portion 13 extending in the width direction of the column 1 is provided on the inner upper side of the column 1, and the assembly insertion portion on the rear end side of the cylinder 121S is attached to the assembly shaft portion 13. 121T, the tip side of the piston rod 121P is assembled in the strut 1 so as to be swingable in the longitudinal direction X (horizontal direction in FIG. 5) of the lifting rack 100. As shown in FIG. An elevating body 127 that ascends and descends along the column 1 is provided at the tip of the piston rod 121P. As shown in FIG. 7(b), the elevator 127 is provided with rollers 127R that roll on guide rails 17G extending in the vertical direction Z provided inside the column 1. As shown in FIG.

The rope transmission mechanism 122 incorporates movable pulleys 125A and 125B, fixed pulleys 123 and 124, and a wire rope 126, as shown in FIGS. The movable pulleys 125A and 125B here have the same diameter, and as shown in FIG. , and rotates around a common rotary shaft 15 (rotational axis R15) extending in the width direction (horizontal direction Y) of the column 1. The fixed pulleys 123 and 124 have different diameters here, and as shown in FIG. It rotates around the axis 14 (rotational axis R14) (see FIG. 5). The wire rope 126 is a single rope and is wound alternately around each of the movable pulleys 125A and 125B and each of the fixed pulleys 123 and 124 once.

Specifically, as shown in FIGS. 5 to 7, the wire rope 126 has one end 126A (starting end: see FIG. 6) of the wire rope fixing portion 16 (shaft-like portion one end of the piston rod 121P, and is wound around one of the movable pulleys 125A attached to the tip of the piston rod 121P (elevating body 127). It continues to be wound alternately around the fixed pulley 123 arranged on the base end side of the cylinder 121S and the other moving pulley 125B arranged on the tip end (lifting body 127) side of the piston rod 121P, and It is wound around the remaining fixed pulley 124 attached to the base end side of the cylinder 121S. That is, the wire rope 126 is wound in the order of the movable pulley 125A, the fixed pulley 123 (intermediate fixed pulley), the movable pulley 125B, and the fixed pulley 124 (terminal fixed pulley) from the one end 126A (starting end) side to be hooked. be.

The other end 126B (terminus: see FIG. 5) of the wire rope 126 is directly or indirectly connected to the lifting rack 100. As shown in FIG. As a result, the lift carriage 105 descends by retracting (contracting) the piston rod 121P and ascends by projecting (extending). The other end 126B of the wire rope 126 is directly connected to the lift carriage 105 here. Since the lifting rack 100 is integrally attached to the lifting truck 105 here, it can be said that the other end 126B of the wire rope 126 is directly connected to the lifting rack 100 .

By forming the rope transmission mechanism 122 using the movable pulleys 125A and 125B, the fixed pulleys 123 and 124, and the wire rope 126 in this way, an empty space is created in the lower part of the inside of the column 1. This empty space is utilized by the chain transmission mechanism and is effectively utilized.

As shown in FIG. 4, the lifting drive means 110 includes an upper limit switch 171 as upper stage position detection means for detecting that the lifting rack 100 is in the upper stage (predetermined upper stage position), and a lower stage limit switch 172 as a lower stage position detection means for detecting that it exists in the lower stage (predetermined lower stage position). These limit switches 171 and 172 are connected to the control means 500 (502) (see FIG. 16), and the control means 500 controls the upper stage limit switch as an upper stage position detection means when the elevator rack 100 is driven upward by the elevator drive means 110. When the switch 171 detects the lifting rack 100, the lifting driving means 110 is stopped to drive up. Similarly, the control means 500 causes the elevation drive means 110 to lower when the upper limit switch 171 as the lower position detection means detects the elevation rack 100 when the elevation drive means 110 drives the elevation rack 100 downward. stop.

In addition, as shown in FIG. 3, the upper and lower two-level bicycle parking facility 1000 includes, for each lifting rack 100, a horizontal direction Y extending from the supporting column 1 on which the lifting rack 100 is supported to at least the adjacent supporting column 1 in a plan view. It is arranged on the ground surface E (reference plane) to set security areas D that have a width and extend in one side in the longitudinal direction X from the fixed rail 2, and the presence of the slide rack 200 is individually checked in each security area D. A detecting means 3 for detecting is provided (see FIG. 14). Each detection means 3 is connected to a control means 500 (502) (see FIG. 16), and the control means 500 detects the presence of the slide rack 200 in the caution area D corresponding to one of the detection means 3. , drive stop command is always output to the lifting drive means 110 that drives the lifting rack 100 corresponding to the detecting means 3 regardless of whether or not the bicycle BCL is mounted.

Further, the detection means 3 here is a bar-shaped or plate-shaped detection member 30 ( zone sensor), and the presence or absence of the slide rack 200 is detected by contact with the detection member 30 . Furthermore, the detection member 30 supports the lateral Y slide of the slide rack 200 together with the fixed rail 2 from below, and the presence or absence of the bicycle BCL is determined by vertical movement (vertical movement due to load) accompanying passage of the slide rack 200. Detect presence or absence regardless.

The detection member 30 extends in the horizontal direction Y in an inverted gutter shape with an open bottom surface, and both ends 30S, 30S of the detection member 30 form curved portions that descend outward. As a result, the upper surface 30a of the detection member is inclined outwardly at both ends 30S, 30S. The base member 39 is positioned below the detection member 30 , extends in the same direction (horizontal direction Y) as the detection member 30 , and is fixed to the ground surface E. The swing arm 33 moves the detection member 30 from the initial position with respect to the base member 39 toward one side (the right side in FIG. 8) in the horizontal direction Y and downward along a predetermined swing locus so that the detection member 30 moves downward. A pair of tilted swing arms 33, 33 constitute a parallel crank mechanism.

The detection member 30 and the base member 39 have swing range defining portions 35 and 36 that define the swingable range of the detection member 30 . The swing range regulating portion 35 is a lower limit position regulating portion 35 (wall portion) rising from a plurality of positions in the length direction of the bottom wall portion of the gutter-shaped base member 39 , and the upper end thereof contacts the lower surface of the detection member 30 . Further descent of the detection member 30 is restricted at the position (swing lower limit position). The swing range regulating portion 36 is an upper limit position regulating portion 36 (wall portion) rising from the bottom wall portion (ceiling wall portion) of the reverse gutter-shaped detection member 30, and the lower limit position regulating portion 35 (wall portion). At the position (swing upper limit position) that contacts the projecting contact portion 36t (here, the bolt member penetrating the lower limit position defining portion 36) projecting in the lateral direction Y, the other side of the detecting member 30 in the lateral direction Y (Fig. 8 to the left), that is, further upward movement of the detection member 30 is restricted.

The sensor urging member 38 is connected to both the detection member 30 and the base member 39, always urges the detection member 30 upward with respect to the base member 39, and holds it at the swing upper limit position (initial position). . The sensor urging member 38 constantly urges the detection member 30 within the swingable range upward and holds it at the predetermined upper limit position unless a downward external force acts on the detection member 30 . The sensor biasing member 38 here uses an extension coil spring.

The detection unit 34 is a sensor that detects the descent of the detection member 30 . The detection unit 34 here is a limit switch that detects that the switch knob 34P is pushed downward, is connected to the control means 500, and outputs the detection result to the control means 500. FIG.

Each detection member 30 here has a length (for example, 1300 mm) that is about the width of a bicycle (mainly about a width slightly wider than the handle width). The column 1 and the lifting rack 100 are arranged at the center position of the detection member 30 in the horizontal direction Y, and the warning area D is within the length range of the detection member 30 including immediately below the lifting rack 100 in the horizontal direction Y. is set to Furthermore, each lifting rack 100 here protrudes in the same direction of the longitudinal direction X from the columns 1 arranged in the horizontal direction Y.

The detection unit 34 is connected to the control means 500 (see FIG. 16) and outputs operation results (sensing results) to the control means 500 . When the lifting rack 100 is lifted, the operator performs a pushing operation (lifting operation) on the foot-operated pedal 154 of the lifting rack 100, whereby the sensing unit 153 senses the operation of the foot-operated pedal 154, and controls the foot-operated pedal 154. Means 500 outputs a lift drive command to corresponding lift drive means 110 .

Each lifting rack 100 has a display means 161 for displaying whether or not the corresponding lifting drive means 110 can be driven based on the operator's operation. and an operation means 162 that can be operated by the operator when displaying the possibility. When outputting a drive stop command to the elevation drive means 110, the control means 500 displays on the corresponding display means 161 that the operator cannot operate and disables the corresponding operation means 162. 3 detects the absence of the slide rack 200, the corresponding display means 161 displays that the operator can operate.

The display means 161 and the operation means 162 here are provided at the rear end of the lifting rack 100 in the longitudinal direction X (right end in FIGS. 9 and 10) as an illuminated push button 160 having both functions.

The illuminated push button 160 is provided on a guard frame 170 provided at the rear end portion of the lifting rack 100 in the longitudinal direction X, and has a light source such as an LED inside, and the operation surface can emit blue light as a display means 161 that can emit light. It has a lamp (green light emitting part). At the same time, the illuminated push button 160 also functions as an operating means 162 for lowering the lifting rack 100, and also functions as a lowering operation section (operating means, lowering operating means), and is connected to the control means 500 (see FIG. 16). When the elevation driving means 110 can be driven, the control means 500 lights the corresponding illuminated push button 160 to indicate that the illuminated push button 160 can be operated downward by the operator. On the other hand, when the control means 500 outputs a drive stop command to the elevation driving means 110, the corresponding illuminated push button 160 is turned off to indicate that the operator cannot operate the illuminated push button 160 to descend. .

When any of the detecting means 3 detects the presence of the slide rack 200 in the corresponding caution area D, the driving stop command to the lifting/lowering driving means 110 is issued by the lifting/lowering driving means of the lifting rack 100 corresponding to the detection means. 110.

In addition, when a plurality of illuminated push buttons 160 (display means 161) simultaneously display (in this case, simultaneously light up) that the operator can operate the illuminated push buttons 160, the control means 500 controls the illuminated push button operated first by the operator. 160 (operating means 162) only to the up/down driving means 110 corresponding to the driving command. As a result, in the upper and lower two-tiered bicycle parking facility 1000, only one of the plurality of lifting racks 100 can be lifted, and the remaining racks cannot be lifted.

Hereinafter, the overall operation of the upper and lower two-level bicycle parking facility 1000 of this embodiment will be described with reference to the flow charts of FIGS. 17 to 20. FIG.

As shown in FIG. 17, the main control unit 501 first instructs all the individual control units 502 to execute the initialization control S0 in M0 by operating the reset switch 503 (start switch: see FIG. 16). to output Each individual control unit 502 that receives this executes initialization control in S0.

The reset switch 503 may be a push switch or the like provided somewhere in the upper and lower two-tier bicycle parking facility 1000, or may be a switch that can be remotely operated from outside the upper and lower two-tier bicycle parking facility 1000. There may be.

Specifically, as shown in FIG. 18, each individual control unit 502 sets 0 to the lighting flag BF (blue lamp flag) associated with the illuminated push button 160 (blue lamp) in S01 to turn on the illuminated push button 160 (blue lamp). 160 is turned off (indicating that the corresponding lifting rack 100 cannot be lifted), and in S02 both the down switch flag DF and the up switch flag UF are set to 0 to configure the down operation part. The sensing section 154 constituting the lifting operation section is turned off, and both the motor down flag MDF and the motor up flag MUF relating to the electric motor 111 are set to 0 in S03 to bring the lifting rack 100 into the stop holding state. Each individual control unit 502 that has completed the initialization control S0 transmits the execution result of the initialization control S0 to the main control unit 501 in S00 of FIG.

The main control unit 501 that has received the execution result of the initialization control S0 from each individual control unit 502 outputs an execution command of the safety confirmation control S1 to all the individual control units 502 at M1 as shown in FIG. . All the individual control units 502 that have received this execute safety confirmation control in S1.

Specifically, as shown in FIG. 19, each individual control unit 502 determines whether or not the detection unit 34 of the detection means 3 (zone sensor) is ON in S11. When the detection unit 34 is ON, each individual control unit 502 sets the lighting flag BF (blue lamp flag) to 0 (turns off the illuminated push button 160) in S19, and ends the safety confirmation control. On the other hand, when the detection unit 34 is OFF, each individual control unit 502 sets the lighting flag BF (blue lamp flag) to 1 in S12 to light the illuminated push button 160 (allows downward operation). Subsequently, each individual control unit 502 determines whether or not the illuminated push button 160 (down switch) is OFF in S13. When the illuminated push button 160 (descent switch) is ON, each individual control unit 502 sets the descent switch flag DF to 1 and the up switch flag UF to 0 in S14 to perform safety confirmation control. exit. On the other hand, when the illuminated push button 160 (down switch) is OFF, each individual control unit 502 sets the down switch flag DF to 0 in S15, and the sensing unit 153 of the sensing means 150 (bar sensor) in S16. It is determined whether or not (up switch) is ON. When the sensing unit 153 (up switch) is ON, each individual control unit 502 sets the up switch flag UF to 1 in S17, and ends the safety confirmation control. On the other hand, if the sensing unit 153 (up switch) is OFF, each individual control unit 502 sets the up switch flag UF to 0 in S18 and ends the safety confirmation control. Each individual control unit 502 that has completed the safety confirmation control S1 transmits the execution result of the safety confirmation control S1 to the main control unit 501 in S10 of FIG.

The main control unit 501, which has received the execution result of the safety confirmation control S1 from each individual control unit 502, sets the lighting flag BF (blue lamp flag) to 1 and the down switch flag DF to 1 in M2, as shown in FIG. 1, or the individual control unit 502 that first satisfies one of the two conditions that the lighting flag BF (blue lamp flag) is 1 and the up switch flag UF is 1, and the specified individual control unit 502 , an execution command for the up/down drive control S2 is output. The individual control unit 502 that has received this command executes up/down drive control in S2.

Specifically, as shown in FIG. 20, the individual control unit 502 that has received the command to execute the up/down drive control S2 first sets the lighting flag BF (blue lamp flag) to 1 and the down switch flag DF to 1 in S21. It is determined whether or not. When the lighting flag BF (blue lamp flag) is 1 and the descending switch flag DF is 1, the individual control unit 502 sets the motor descending flag MDF to 1 in S22 to descend the lifting rack 100. to output a predetermined driving force from the electric motor 111 .

Then, the individual control unit 502 determines whether or not the detection unit 34 of the detection unit 3 (zone sensor) is ON in S23, and determines whether the detection unit 153 (up switch) of the detection unit 150 (bar sensor) is ON in S24. It is determined whether or not it is ON. The individual control unit 502 continues the descent of the lifting rack 100 as long as both are OFF. This descent ends when the lifting rack 100 reaches a predetermined lower position and the lower limit switch 172 (lower limit switch) turns ON (S25/Y). The descent flag MDF is set to 0 to stop the descent drive of the electric motor 111 to bring the lifting rack 100 into a stop holding state, and the lighting flag BF (blue lamp flag) is set to 0 to turn off the illuminated push button 160. Let

Also, when the sensing portion 153 (lifting switch) of the sensing means 150 (bar sensor) is turned ON while the lifting rack 100 is descending, the individual control portion 502 proceeds to S28, and the lifting rack 100 changes from downward to upward. Processing after S28 will be described later.

On the other hand, if the lighting flag BF (blue lamp flag) is 1 and the down switch flag DF is not 1 in S21, the individual control unit 502 determines in S27 that the lighting flag BF (blue lamp flag) is 1 and It is determined whether or not the up switch flag UF is 1. If the lighting flag BF (blue lamp flag) is 1 and the rise switch flag UF is 1, the individual control unit 502 proceeds to S28.

In S28, the individual control unit 502 sets the motor lift flag MUF to 1, and causes the electric motor 111 to output a predetermined driving force for lifting the lifting rack 100. FIG.

After that, the individual control unit 502 determines in S29 whether or not the detection unit 34 of the detection means 3 (zone sensor) is ON, and as long as it is OFF, the lifting rack 100 continues to rise. This ascending ends when the lifting rack 100 reaches a predetermined upper stage position and the upper stage limit switch 171 (upper limit switch) is turned ON (S30/Y). The lift flag MUF is set to 0 to stop the lift drive of the electric motor 111 to bring the lifting rack 100 into a stop holding state, and the lighting flag BF (blue lamp flag) is set to 0 to turn off the illuminated push button 160. Let

By the way, when the detection unit 34 of the detection means 3 (zone sensor) is turned ON while the lifting rack 100 is being lowered (S23) or raised (S29), the individual control unit 502 sets the motor down flag MDF in S32. Then, the motor up flag MUF is set to 0 to stop driving the electric motor 111 to bring the lifting rack 100 into a stop holding state, and the lighting flag BF (blue lamp flag) is set to 0 to turn on the illuminated push button 160 (blue lamp flag). lamp) is turned off. After that, the individual control unit 502 may output a predetermined alarm sound or warning voice from an alarm output unit (not shown) in S33.

On the other hand, if the lighting flag BF (blue lamp flag) is 1 and the up switch flag UF is not 1 in S27, the individual control unit 502 terminates this elevation drive control.

The individual control unit 502 that has finished the elevation drive control S2 transmits the execution result of the elevation drive control S2 to the main control unit 501 in S20 of FIG. Each individual control unit 502 returns to S0 and executes initialization control again.

If the detection unit 34 of the detection means 3 (zone sensor) is turned ON and the lifting rack 100 is stopped in the previous lifting drive control S2 (FIG. 20), the process returns to S0 and each individual control unit 502 is activated again. When executing from the initialization control S0 (FIG. 17) to the safety confirmation control S1 (FIG. 17), the detection unit 34 of the detection means 3 (zone sensor) is turned OFF in the safety confirmation control S1 (FIG. 19). If so (S11/N), the individual control unit 502 sets the lighting flag BF (blue lamp flag) to 1 in S12 to light the illuminated push button 160, and raises and raises the lifting rack 100 that is stopped. Lowering operation becomes possible (S12). In other words, even if the detection unit 34 of the detection unit 3 (zone sensor) is turned ON in the lifting drive control S2 (FIG. 20) and the lifting rack 100 stops, if the detection unit 34 is turned OFF, the system can be stopped. Ascending operation and descending operation for the lift rack 100 thus performed are enabled.
