Description

Upper and lower two-layer parking facility

Technical Field

The utility model relates to an upper and lower two-layer parking facility.

Background

For example, as shown in patent document 1, there is known an upper and lower two-layer parking facility including: a plurality of carriages which are placed in a crossed manner on a fixed rail arranged on the ground surface and can slide on the fixed rail; and a lifting frame supported by each of the pillars standing on the ground at a predetermined interval so as to protrude in a cantilever shape, the lifting frame being movable up and down along the pillars by driving a motor, the lifting frame being movable up and down between the upper and lower floors in a free space generated by sliding of the carriage located at the lower floor.

In patent documents 1, 2, and 3, a sensor for directly detecting contact with an obstacle (such as a carriage, a bicycle, or an operator) is provided on the bottom surface side of the crane, and when the sensor contacts the obstacle during lowering of the crane, the motor is stopped or reversed (switched to an upward state) to avoid damage (including injury).

Incidentally, focusing on the lifting frame and the plurality of carriages located at the lower layer in the process of being lowered from the upper layer, there is a possibility that the contact area is varied and time-to-time varies depending on the relative positional relationship of the two in a plan view, whether or not the bicycle is mounted, the size of the mounted bicycle (in particular, the handle bar width), and the like. Therefore, it is difficult to ensure safety over a wide range by the sensors provided on the bottom surface side of the lifter as in patent documents 1, 2, and 3.

Further, the sensor is a sensor that directly senses contact with an obstacle and stops lowering or reversely rises the crane, and thus there is a possibility that delay may be avoided. When the normal lifting speed is slowed down so as not to cause the avoidance delay, there is a concern that the work efficiency is deteriorated. Further, since the sensor is provided to the moving crane, there is a possibility that the detection range of the sensor continuously fluctuates with the lifting movement of the crane, and the detection range itself becomes unstable. In addition, although the occurrence frequency is low, even if the sensor comes into contact with an obstacle during the lifting of the crane, danger avoidance cannot be achieved.

On the other hand, patent documents 3, 4, and 5 disclose the following technologies: by detecting the motor load, the sag of the wire, the sag of the chain, and the like, the contact between the crane and the obstacle is indirectly sensed, and the lowering and the reverse lifting of the crane are stopped. However, in case these indirect sensing units are used, the hazard avoidance may be further delayed compared to the direct sensing. In addition, since phenomena such as motor load, wire sag, and chain sag may occur due to other factors than contact with obstacles, there is also a risk of false detection and false operation.

Patent document 3 also describes that a human sensor is provided on a ceiling surface of a parking place, but an obstacle is shielded by a shade of a crane, a carriage, a bicycle mounted on the crane, or the like, and is difficult to accurately detect, and in addition, it is difficult to provide the vehicle in an outdoor parking place, and there are many problems in terms of ensuring safety.

Disclosure of utility model

Problems to be solved by the utility model

The utility model provides an up-down two-layer parking facility, which can ensure the safety of parking operation by stopping the driving of a lifting driving unit before the contact of a lifting frame and an obstacle (particularly a sliding frame and a carrying bicycle) occurs.

Means for solving the problems and effects of the utility model

In order to solve the above problems, the upper and lower two-layer parking facility of the present utility model has: a plurality of carriages mounted on the fixed rail in a longitudinal direction (corresponding to the length of one bicycle) orthogonal to or diagonally crossing a fixed rail (single or parallel) arranged in a horizontal direction set on a reference surface (for example, the ground surface) in a plan view, (and capable of allowing a bicycle to come in and go out from one side of the longitudinal direction, and capable of sliding on the fixed rail (in the horizontal direction) regardless of whether or not the bicycle is mounted on the fixed rail); and a lifting frame supported by each of the columns erected from the reference surface at a predetermined interval in the lateral direction so as to protrude in the longitudinal direction (corresponding to the length of one bicycle) (and allowing the bicycle to come in and go out from one side in the longitudinal direction at the lower layer position, regardless of whether or not the bicycle is mounted), and capable of lifting along the columns, wherein the lifting frame is capable of lifting between the upper layer and the lower layer in a free space generated by sliding of the carriage located at the lower layer in the lateral direction,

The upper and lower two-layer parking facility is provided with:

A lift driving unit (including a driving source and a transmission mechanism, for example) provided for each of the lifts and configured to generate driving forces (based on electromotive force, fluid pressure, or the like) for lifting and lowering the lift along the corresponding column;

a control unit (of an electric signal system, a fluid pressure signal system, etc.) for individually controlling the lifting drive unit to lift the lifting frame up and down; and

A detection means arranged on a reference surface so as to set a guard area for each of the lifters, the guard area having a width extending from the support column supporting the lifter to at least a lateral direction of the support column adjacent to the support column in a plan view and extending from the fixed rail to one side in a longitudinal direction, the detection means individually detecting the presence of the carriage in each of the guard areas,

When any one of the detecting units detects the presence of the carriage in the corresponding guard region, the control unit always outputs a drive stop command to the elevation driving unit that drives the elevation carriage corresponding to the detecting unit, regardless of whether or not a bicycle is mounted.

In this way, the guard area is fixedly formed on the reference surface by the detection means disposed on the reference surface, and whether or not the carriage is present in the guard area is detected before the lifting drive of the lifting frame, so that the driving of the lifting drive means can be stopped before the lifting frame comes into contact with the obstacle (particularly, the carriage and the mounted bicycle), and the parking operation can be performed safely and quickly.

Further, since the guard area is stably set within the predetermined range as seen in a plan view regardless of whether the bicycle is mounted or not, the risk of the lifting frame coming into contact with the obstacle during the lifting movement can be easily avoided.

The carriage includes a type that is slidably mounted on a single fixed rail disposed in the lateral direction and a type that is slidably mounted across a pair of fixed rails disposed in parallel in the lateral direction. The present invention also includes a type in which the lifter protrudes from each pillar only in one of the left and right directions in a plan view with respect to the arrangement direction (lateral direction) of the pillars, and a type in which the lifter protrudes from each pillar alternately in the left and right directions in a plan view. The drive source of the elevating drive means includes an electric motor, a hydraulic cylinder, a pneumatic cylinder, and the like, and the detection means includes a non-contact type (optical type, ultrasonic type, electromagnetic wave type, and the like) in addition to the contact type.

Each of the above-mentioned lifters protrudes from the columns arranged in the lateral direction in the same direction as the longitudinal direction,

The guard region is set so as to overlap each other between adjacent pillars in a plan view.

By overlapping a part of the guard area in this way, the safety of the crane against the obstacle during the lifting movement is further improved, and more cranes and carriages can be provided (accommodated) in the parking facility.

Each of the above-mentioned lifting frames further comprises: a display unit (e.g., green light) for displaying whether or not the corresponding lift driving unit can be driven based on an operation of the operator; and an operation unit (e.g., a lowering side push button switch or a raising side foot switch) that can be operated (lowered or raised) by an operator when the display unit displays that the lifting driving unit can be driven (e.g., lighted),

When the control unit outputs a drive stop instruction to the elevation drive unit, the control unit displays that the operator cannot perform (e.g., descend) operation (e.g., go out) and sets the corresponding operation unit to be inoperable (e.g., turn off the push button switch) on the corresponding display unit,

When the detection unit detects that the carriage is not present, the control unit displays that the operator can perform (e.g., descend) operation (e.g., light up) on the corresponding display unit.

In this way, when the carriage is present in any one of the guard areas, the corresponding operation means is rendered inoperable, and when the carriage is not present, the operable means is displayed on the corresponding display means, so that the safety of the manual operation can be improved.

The detection means includes a rod-like or plate-like detection member (for example, a zone sensor) disposed on the reference surface in parallel with the fixed rail across the entire width of the guard zone in a plan view,

The presence or absence of the carriage is detected by contact with the detection member.

By such a contact type detection means, the presence or absence of the carriage can be reliably detected.

The detection member supports the lateral sliding of the carriage from the lower side together with the fixed rail, and detects whether the carriage is present or not (irrespective of whether the bicycle is mounted or not) by the upward and downward movement accompanying the passage of the carriage.

In this way, the presence or absence of the carriage can be reliably detected by the detection means for detecting the vertical movement caused by the load.

The upper and lower two-layer parking facility further includes a biasing means (e.g., a gas spring, a constant load spring, a weight, etc.) for biasing the lifting frame in a direction to always rise to assist the driving force of the lifting driving means,

The lift drive unit includes an electric motor as a drive source, and a chain transmission mechanism driven by the electric motor, the chain transmission mechanism having: sprockets axially supported in the upper and lower interiors of the struts, respectively; and a flat ring chain wound around the sprockets inside the strut and having both ends connected to the lifter, and

The force applying unit is provided with a rope transmission mechanism, and the rope transmission mechanism is assembled with: two movable pulleys connected to the front end portion of a piston rod that protrudes downward from a cylinder of a gas spring having a base end portion mounted in the upper portion of the strut and that exerts traction force; two fixed pulleys fixed to the inside of the pillar at a position higher than the cylinder; and a single wire rope alternately wound one turn on each movable sheave and each fixed sheave.

Thus, the chain transmission mechanism and the rope transmission mechanism can be compactly accommodated in the pillar.

The bottom surface of each of the above-mentioned lifters is further provided with a sensing means (for example, a rod-like sensor is included as a sensing member) for sensing that the lifters are in contact with an obstacle located below the lifters,

When the sensing means corresponding to any one of the lifting frames is in contact with the obstacle during the descending process, the control means outputs a lifting drive command to the lifting drive means corresponding to the lifting frame during the descending process, regardless of whether or not the bicycle is mounted.

By providing such a sensing means, double safety when the crane is lowered can be ensured.

Detailed Description

Hereinafter, embodiments of the present utility model will be described with reference to examples shown in the drawings.

As shown in fig. 1 to 3, the upper and lower two-layer parking facility 1000 of the present embodiment has a plurality of carriages 200 and lifters 100.

The racks 100 and 200 are elongated in the longitudinal direction X in the forward and backward direction (front and rear direction) for mounting and unloading the bicycle BCL, and extend in a cantilever manner in a groove shape with an open upper surface. Front ends (rear ends) of the racks 100 and 200 are formed with an inlet/outlet 4 for loading/unloading the bicycle BCL. Here, the brackets 100 and 200 are provided with a pair of supports 5 (side guards) for preventing the mounted bicycle BCL from turning on its side on both sides in the width direction. A tire fence 6 for holding a front loading wheel (for example, a front wheel) of the mounted bicycle BCL is provided on the front side of the rack 100.

As shown in fig. 1 and 2, each carriage 200 is placed in the longitudinal direction X, and the longitudinal direction X is orthogonal or obliquely crossed to a plurality of single or parallel fixed rails 2 arranged in a straight line along the lateral direction Y (see fig. 2) provided on the ground surface E (reference surface) in a plan view, and each carriage 200 is slidable on the fixed rail 2. Each carriage 200 has a length corresponding to one bicycle in the longitudinal direction X, and can be moved in and out of the bicycle BCL from one side in the longitudinal direction X, and each carriage 200 can slide in the lateral direction Y on the fixed rail 2 regardless of whether or not the bicycle BCL is mounted.

The respective carriages 200 are configured to be laterally slidably movable along a fixed rail 2 provided on the ground surface E via a plurality of rollers 8 (rolling elements) mounted on the bottom surface side of one end portion (here, the front end portion). Further, a caster 9 is attached to the other end portion (herein, the rear end portion) of each carriage 200, and the caster 9 is configured to be grounded to the ground surface E (reference surface) to support the carriage 200, and at this time, to be capable of rolling in the lateral direction Y. With these structures, each carriage 200 is formed so as to be slidable in the lateral direction Y.

As shown in fig. 1 and 3, the lifting frame 100 is supported so as to protrude in a cantilever-like manner in the longitudinal direction X on each of the columns 1 standing at a constant pitch from the ground surface E (reference surface) along the lateral direction Y (see fig. 3), and is capable of lifting along the columns 1. Specifically, as shown in fig. 2, each of the lifters 100 can be lifted and lowered between the upper layer (the predetermined upper layer) and the lower layer (the predetermined lower layer) in the empty space ES generated by the sliding of the lower-layer carriage 200 in the lateral direction Y (the arrangement direction of the struts 1) (that is, in a state where there is no empty space right below as shown in fig. 1, the lifting and lowering cannot be performed). Each of the lifting frames 100 is supported on each of the columns 1 so as to protrude in a cantilever manner in the longitudinal direction X by a length corresponding to one bicycle BCL, and is capable of allowing the bicycle BCL to come in and go out from one side in the longitudinal direction X at a lower position and to be lifted up and down along the column 1 irrespective of whether or not the bicycle BCL is mounted.

As shown in fig. 1 and 4 to 7, the vertical two-layer parking facility 1000 includes: a lift driving unit 110 provided for each lift 100, and generating driving forces based on electromotive force, fluid pressure, or the like (in this case, electromotive force) for vertically lifting the lift 100 along the corresponding column 1; and a control unit 500 (see fig. 16) such as an electric signal system or a fluid pressure signal system for controlling the vertical movement of the lifting frame 100 by the lifting drive unit 110. As shown in fig. 16, the control unit 500 here includes individual control units 502 corresponding to the respective columns 1 and the lifting frame 100, and a main control unit 501 to which these individual control units 502 are connected. The individual control unit 502 is connected to a detection unit 3 (detection unit 34), a sensing unit 150 (sensing unit 154), an illuminated button 160, a limit switch 171, a limit switch 172, an electric motor 111, and the like, which will be described later, with respect to the corresponding lifter 100. The control unit 501 and the control unit 502 are known microcomputers having a CPU or the like, and various programs for controlling the vertical movement of the lift 100 by the lift driving unit 110 are stored in a predetermined storage unit, and these programs can be executed by the CPU.

As shown in fig. 1 and 4 to 7, the vertical two-layer parking facility 1000 is provided with a biasing means 120, and the biasing means 120 is configured to bias each lift 100 in a direction to always rise and assist the driving force of the lift driving means 110.

As shown in fig. 4, the elevation driving unit 110 includes an electric motor 111 as a driving source. The driving force of the electric motor 111 is smaller than the weight of the crane in the real vehicle state in which the bicycle BCL is mounted, and the lifting force of the urging unit 120 is larger than the weight of the crane in the empty vehicle state in which the bicycle BCL is not mounted. Here, assuming that the weight of the lift 100 is 10kg and the weight of the bicycle BCL is 40kg at the maximum, when the lift 100 is lifted, the urging means 120 exerts a constant lifting urging force capable of pulling half of the total weight by 25kg in order to pull (lift) the total weight, and the lift driving means 110 exerts a constant lifting driving force (motor torque: 10.6 Nm) capable of pulling the remaining half by 25 kg. When the lift 100 is lifted, these constant lifting forces and constant lifting driving forces are exerted regardless of the actual state in which the bicycle BCL is mounted on the lift 100 and the empty state in which the bicycle BCL is not mounted. When the constant upward force of the force applying unit 120 is always applied during the descent of the crane 100, the lift driving unit 110 generates a constant downward driving force exceeding the constant upward force applied regardless of the actual state and the empty state of the crane 100. When the lifter 100 is stopped, the electric motor 111 stops driving, and the self-locking of the worm wheel 116 connected to the electric motor 111 acts to hold the lifter 100 stopped.

The electric motor 111 may have a regenerative braking function according to a torque corresponding to an upward biasing force of the biasing means 120 exceeding the weight of the overhead crane when the overhead crane 100 is lifted in the empty state. However, in this case, it is necessary to change the structure of a part.

As shown in fig. 4, the elevation drive unit 110 includes a chain transmission mechanism 112 driven by an electric motor 111. As shown in fig. 5, the chain transmission mechanism 112 has: a sprocket 113 and a sprocket 114, which are respectively supported by the upper and lower inner portions of the pillar 1; and a flat ring chain 115 wound around these sprockets 113 and 114 inside the strut 1, and connected at both ends to the crane 100. The electric motor 111 rotates the upper sprocket 113 via the worm wheel 116. As shown in fig. 5, a lifting carriage 105 that lifts along the column 1 is provided at the front end of the lifting carriage 100, and one end 115A of a endless loop 115 is connected to the lifting carriage 105 from above (sprocket 113 side) while the other end 115B is connected to the lifting carriage 105 from below (sprocket 114 side). A roller 105R (see fig. 5) that rolls on a guide rail 15G (see fig. 7 b) extending in the up-down direction Z provided on the rear side surface of the column 1 is assembled to the elevating carriage 105.

As shown in fig. 4 and 5, the urging unit 120 has a gas spring 121 as an upward urging force generating source. The urging means 120 includes a rope transmission mechanism 122 for transmitting the upward urging force to the corresponding lifting frame 100.

As shown in fig. 5, the gas spring 121 for biasing the lift 100 (lift truck 105) so as to always be lifted upward includes: a cylinder 121S having a base end mounted inside the upper portion of the pillar 1; and a piston rod 121P protruding downward from the cylinder 121S to exert traction force. As shown in fig. 6, an assembly shaft portion 13 extending in the width direction of the strut 1 is provided on the upper side of the inside of the strut 1, and the assembly shaft portion 13 is inserted into an assembly insertion penetration portion 121T penetrating the rear end side of the cylinder 121S, so that the front end side of the piston rod 121P can swing in the longitudinal direction X (left-right direction in fig. 5) of the crane 100 in the strut 1. A lifting body 127 that lifts along the column 1 is provided at the front end portion of the piston rod 121P. As shown in fig. 7 (b), a roller 127R is assembled to the elevating body 127, and the roller 127R rolls on a guide rail 17G extending in the up-down direction Z provided in the pillar 1.

As shown in fig. 4 and 5, a movable sheave 125A, a movable sheave 125B, a fixed sheave 123, a fixed sheave 124, and a wire rope 126 are incorporated in the rope transmission mechanism 122. The movable pulleys 125A and 125B are formed to have the same diameter, and are connected to the distal end portion (lifter 127) of the piston rod 121P that protrudes downward from the cylinder 121S of the gas spring 121 whose base end portion is mounted in the upper portion of the strut 1 to exert traction, and rotate about a common rotation shaft 15 (rotation axis R15) extending in the width direction (lateral direction Y) of the strut 1, as shown in fig. 7 a. The diameters of the fixed pulleys 123 and 124 are different from each other, and as shown in fig. 6, the fixed pulleys are fixed to the inside of the strut 1 at positions higher than the cylinder 121S, and rotate about the rotation shaft 14 (rotation axis R14) extending in the width direction of the strut 1 (see fig. 5). The wire rope 126 is a single rope, and is wound around each of the movable pulleys 125A and 125B and each of the fixed pulleys 123 and 124 alternately one turn.

Specifically, as shown in fig. 5 to 7, one end 126A (starting end: see fig. 6) of the wire rope 126 is hooked and fixed to the wire rope fixing portion 16 (one end of the shaft portion) provided at an upper position in the strut 1, and from this hooked position, the wire rope is wound around one movable pulley 125A attached to the front end portion (lifter 127) side of the piston rod 121P, and from this movable pulley 125A, the wire rope is wound around the fixed pulley 123 disposed on the base end portion side of the cylinder 121S and the other movable pulley 125B disposed on the front end portion (lifter 127) side of the piston rod 121P, and further wound around the remaining fixed pulley 124 attached to the base end portion side of the cylinder 121S. That is, the wire rope 126 is wound around the movable pulley 125A, the fixed pulley 123 (intermediate fixed pulley), the movable pulley 125B, and the fixed pulley 124 (end fixed pulley) in this order from the hooked end 126A (start end).

The other end 126B (terminal end: see fig. 5) of the wire rope 126 is directly or indirectly connected to the hoist frame 100. Thereby, the lifting carriage 105 is lowered by the retraction (contraction) of the piston rod 121P, and raised by the projection (extension). The other end 126B of the wire rope 126 is directly connected to the lifting carriage 105. Since the crane 100 is integrally assembled to the crane carriage 105, the other end 126B of the wire rope 126 may be directly connected to the crane 100.

In this way, by forming the rope transmission mechanism 122 using the movable pulley 125A, the movable pulley 125B, the fixed pulley 123, the fixed pulley 124, and the wire rope 126, a free space is created in the lower side of the inside of the strut 1. The free space is effectively utilized by the chain transmission mechanism.

As shown in fig. 4, the elevation drive unit 110 includes: an upper limit switch 171 as an upper position detection unit that detects that the lift 100 is present at an upper layer (a predetermined upper position); and a lower limit switch 172 as lower position detection means for detecting that the lift 100 is located at a lower layer (predetermined lower position) below the upper layer. These limit switches 171 and 172 are connected to the control unit 500 (502) (see fig. 16), and when the lift 100 is driven upward by the lift driving unit 110, the control unit 500 stops the lift driving unit 110 from driving upward when the lift 100 is detected by the upper limit switch 171 as the upper position arrival detecting unit. Similarly, when the lift 100 is driven downward by the lift driving unit 110, if the lift 100 is detected by the lower limit switch 172, which is a lower position arrival detecting unit, the control unit 500 stops the lift driving unit 110 from driving downward.

As shown in fig. 3, the vertical two-story parking facility 1000 includes a detection means 3 (see fig. 14), and the detection means 3 is disposed on the ground surface E (reference surface) in order to set a guard area D for each of the cranes 100, the guard area D having a width extending from the pillar 1 supporting the crane 100 at least in the lateral direction Y of the adjacent pillar 1 in a plan view and extending from the fixed rail 2 to one side in the longitudinal direction X, and the detection means 3 detecting the presence of the carriages 200 in each guard area D. Each of the detecting units 3 is connected to the control unit 500 (502) (see fig. 16), and when any one of the detecting units 3 detects the presence of the carriage 200 in the corresponding guard region D, the control unit 500 always outputs a drive stop command to the lift driving unit 110 that drives the lift 100 corresponding to the detecting unit 3, regardless of whether or not the bicycle BCL is mounted.

The detection unit 3 here includes a rod-shaped or plate-shaped detection member 30 (area sensor) disposed on the ground surface E (reference surface) in parallel to the fixed rail 2 across the entire width of the lateral direction Y of the guard area D in a plan view, and detects the presence or absence of the carriage 200 by contact with the detection member 30. Further, the detection member 30 supports the lateral Y sliding of the carriage 200 from the lower side together with the fixed rail 2, and detects whether or not the carriage 200 is present by the upward and downward movement (upward and downward movement based on the load) associated with the passage of the carriage 200, irrespective of whether or not the bicycle BCL is mounted.

Specifically, as shown in fig. 8, the detection unit 3 includes the above-described detection member 30 (area sensor), and includes the base member 39, the swing arm 33, the sensor urging member 38, and the detection portion 34, and the area sensor 30 constitutes a main portion of the detection unit 3.

The detection member 30 is formed in a reverse groove shape with an open lower surface and extends in the lateral direction Y, and both ends 30S, 30S thereof are formed as curved portions that descend toward the outside. Thereby, the detection member upper surface 30a is formed at both ends 30S, 30S thereof as an inclined surface that descends outward. The base member 39 is positioned below the detection member 30, is formed in a groove shape with an open upper surface, extends in the same direction (lateral direction Y) as the detection member 30, and is fixed to the ground surface E. The swinging arm 33 connects the detection member 30 to the base member 39 so as to be capable of reciprocating swinging (in the Q1 direction in fig. 8) from the initial position along a predetermined swinging locus (a rotation locus) on one side (the right side in fig. 8) toward the lateral direction Y and below, so that the detection member 30 moves downward, and the pair of swinging arms 33 and 33 arranged obliquely constitute a parallel crank mechanism.

The detection member 30 and the base member 39 have a swing range defining unit 35 and a swing range defining unit 36 that define the swingable range of the detection member 30. The swing range defining portion 35 is a lower limit defining portion 35 (wall portion) that is raised from a plurality of portions in the longitudinal direction of the bottom wall portion of the groove-shaped base member 39, and further lowering of the detection member 30 is restricted at a position (swing lower limit position) where the upper ends thereof contact the lower surface of the detection member 30. The swing range defining portion 36 is an upper limit defining portion 36 (wall portion) that descends from a bottom wall portion (top wall portion) of the reverse groove-shaped detecting member 30, and further movement of the detecting member 30 to the other side (left side in fig. 8) in the transverse direction Y, that is, further elevation of the detecting member 30 is restricted at a position (swing upper limit position) that contacts a protruding contact portion 36t (here, a bolt member that penetrates the lower limit defining portion 36) protruding from the lower limit defining portion 35 (wall portion) in the transverse direction Y.

The sensor urging member 38 is coupled to both the detection member 30 and the base member 39, and urges the detection member 30 upward with respect to the base member 39 at all times, and holds the detection member at the swing upper limit position (initial position). The sensor urging member 38 always urges the detection member 30 in the swingable range upward and holds the detection member 30 at the predetermined upper limit position as long as no downward external force acts on the detection member 30. The sensor biasing member 38 here uses a tension coil spring.

The detection unit 34 is a sensor that detects the lowering of the detection member 30. The detection unit 34 is a limit switch for detecting that the switch knob 34P is pushed downward, and is connected to the control unit 500 to output the detection result to the control unit 500.

Each of the detecting members 30 herein has a length (for example, 1300 mm) of a lateral width (mainly, a width slightly wider than a width of a handlebar) of the bicycle. The column 1 and the lifter 100 are arranged at the center position of the detecting member 30 in the lateral direction Y, and the guard region D is set within the length range of the detecting member 30 including immediately below the lifter 100 in the lateral direction Y. Here, the respective lifters 100 protrude in the same direction as the longitudinal direction X from the struts 1 aligned in the lateral direction Y, and the guard region D of each lifter 100 is set so that the struts 1 and lifters 100 are arranged more densely in the lateral direction Y and overlap each other in a plan view between adjacent struts 1.

Specifically, as shown in fig. 3, the detecting member 30 includes: a plurality of first detecting members 31 arranged in a straight line along the lateral direction Y at a first position in the longitudinal direction X of the lifter 100; and a plurality of second detecting members 32 arranged in a straight line in the lateral direction Y at a second position different from the first position. The corresponding column 1 and the lifter 100 of each first detection member 31 are located at the center position in the longitudinal direction (the lateral direction Y) thereof, and a warning region D1 as a warning region D is formed directly below the lifter 100 and on both sides of the lateral direction Y. Each second detecting member 32 is also located at the center of the corresponding column 1 and the corresponding crane 100 in the longitudinal direction (the lateral direction Y), and forms a warning region D2 as a warning region D immediately below the crane 100 and on both sides of the lateral direction Y. The pillars 1 and the lifters 100 are arranged at equal intervals so that the pillars and lifters corresponding to the first detection member 30 and the pillars and lifters corresponding to the second detection member 32 are alternately arranged in the lateral direction Y, and the pillars 1 and lifters 100 adjacent to each other in the lateral direction Y are set so as to overlap with each other in the guard areas D1 and D2.

The carriage 200 is configured such that a carriage corresponding to the first detection member 31 and a carriage corresponding to the second detection member 32 are alternately arranged in the lateral direction Y, and rollers 7 rolling in the longitudinal direction (lateral direction Y) of the respective detection members 31, 32 are assembled on the lower side of the carriage. The detection member 30 is pressed downward by the roller 7. The detection members 30, 30 adjacent to each other in the lateral direction Y are disposed with a gap having a width slightly wider than that of one roller 7 interposed therebetween, and both the detection members 30, 30 adjacent to each other are prevented from being pressed down by the roller 7 at the same time.

As described above, the detection units 3 (area sensors) of the present embodiment are arranged in parallel in two rows as shown in fig. 2 and 3, corresponding to any one of the groups of the column 1 and the crane 100. The number of the struts 1, the lifters 100, and the carriages 200, the arrangement intervals of the struts 1 and the lifters 100, the length of the fixed rail 2, the length of the detection units 3, and the like are adjusted so that at most only one detection unit 3 is in a non-detection state no matter how the carriages 200 are moved along the fixed rail 2. That is, in the up-and-down two-layer parking facility 1000 of the present embodiment, only one lift 100 is configured to be able to be lifted and lowered, and the plurality of lifts 100 cannot be moved at the same time.

As shown in fig. 1, the two-story parking facility 1000 includes a sensing unit 150 on the bottom surface of each of the racks 100, and the sensing unit 150 senses that the rack 100 is in contact with an obstacle W (see fig. 15) located below the rack 100. When the sensing unit 150 corresponding to the descending crane 100 is in contact with the obstacle during the descending operation, the control unit 500 outputs the ascending drive command to the ascending/descending drive unit 110 corresponding to the descending crane 100 regardless of whether the bicycle BCL is mounted.

As shown in fig. 9 to 11, the sensing unit 150 includes a sensing member 151 (rod-like sensor), a boom 152 for swinging the sensing member 151, and a sensing unit 153 for sensing a rise associated with the swinging of the sensing member 151, and the rod-like sensor 151 in contact functions as a main part of the sensing unit 150.

The sensing member 151 is formed in a groove shape with an open upper surface and extends in the longitudinal direction X of the lifter 100. The suspension arm 152 is connected to the sensing member 151 with respect to the crane 100 so as to be capable of reciprocating (in the Q2 direction in fig. 10) along a predetermined swing locus (rotation locus) on one side (front side: left side in fig. 10) and above (upper side in fig. 10) in the longitudinal direction X, so that the sensing member 151 moves downward from the initial position, and the pair of suspension arms 152 and 152 arranged obliquely constitute a parallel crank mechanism.

A foot operation pedal 154 is assembled to the other end (rear end) of the sensing member 151 in the longitudinal direction X, and a swing restricting portion 154b that defines a swing lower limit position of the sensing member 151 is provided to the foot operation pedal 154. Specifically, the foot pedal 154 includes a mounting portion 154b, and the mounting portion 154b extends in a plate shape from the back side of the foot pedal 154a toward the front in the longitudinal direction X (leftward in fig. 10) with respect to the rearward facing foot pedal surface 154 a. The swing lower limit of the sensing member 151 is a position where the sensing member 151 is placed on the placement portion 154b. On the other hand, the swing upper limit of the sensing member 151 is a position where the sensing member 151 contacts the lifter 100. The sensing member 151 is held at the swing lower limit position (initial position) by its own weight as long as no upward external force acts.

The sensing unit 153 is a sensor that senses the rise of the sensing member 151. The sensing unit 153 is a limit switch for detecting that the switch knob 153P (here, the foot operation pedal 154) is pushed forward in the longitudinal direction X (left side in fig. 9 and 10), and outputs a detection result (sensing result) to the control unit 500. When the sensing portion 153 senses a rise accompanied by the swing of the sensing member 151, the control unit 500 outputs a rise driving instruction to the corresponding rise and fall driving unit 110.

The foot operation pedal 154 is provided so that the switch button 153P of the detection unit 34 is pushed in by a lifting operation of pushing in from the rear to the front in the longitudinal direction X (from the right to the left in fig. 9 and 10), and the foot operation pedal 154 constitutes a lifting operation unit 164 (operation means, lifting operation means) together with the detection unit 34. The detection unit 34 is connected to the control unit 500 (see fig. 16), and outputs an operation result (sensing result) to the control unit 500. When the lift 100 is lifted, the operator performs a pushing operation (lifting operation) on the foot operation pedal 154 of the lift 100, and the sensing unit 153 senses the operation on the foot operation pedal 154, and the control unit 500 outputs a lifting drive command to the corresponding lifting drive unit 110.

Each of the lifters 100 includes: a display unit 161 for displaying whether or not the corresponding lift driving unit 110 can be driven based on an operation of an operator; and an operation unit 162 operable by an operator when the display unit 161 displays that the elevation driving unit 110 can be driven. When the control unit 500 outputs the drive stop instruction to the elevation drive unit 110, the corresponding display unit 161 displays that the operator cannot operate and the corresponding operation unit 162 cannot operate, and when the detection units 3 detect that the carriage 200 is not present, the corresponding display unit 161 displays that the operator can operate.

The display unit 161 and the operation unit 162 are provided at the rear end (right end in fig. 9 and 10) of the lifter 100 in the longitudinal direction X as the illuminated push button 160 having the functions of both.

The illuminated button 160 is provided on a guardrail frame 170 provided at the rear end portion of the lifter 100 in the longitudinal direction X, has a light source such as an LED inside, and has a green light (green light emitting portion) as a display unit 161 capable of emitting light on the operation surface. At the same time, the illuminated button 160 also functions as a lowering operation unit (operation unit, lowering operation unit) as an operation unit 162 for lowering the lift 100, and is connected to the control unit 500 (see fig. 16). When the elevation driving unit 110 can be driven, the control unit 500 turns on the corresponding illuminated button 160, and displays that the operator can perform the lowering operation of the illuminated button 160. On the other hand, when the control unit 500 outputs the drive stop instruction to the elevation drive unit 110, the corresponding illuminated button 160 is turned off, and the operator is displayed that the operator cannot perform the lowering operation on the illuminated button 160.

When any one of the detecting units 3 detects the presence of the carriage 200 in the corresponding guard region D, a drive stop command for the lift driving unit 110 is output to the lift driving unit 110 of the lift 100 corresponding to the detecting unit.

When a plurality of illuminated buttons 160 (display means 161) are simultaneously displayed so that the operator can operate (in this case, are simultaneously lit), the control means 500 outputs a drive command only to the lift drive means 110 corresponding to the illuminated button 160 (operation means 162) that was operated first by the operator. Thus, in the upper and lower two-layer parking facility 1000, only one of the plurality of lifters 100 can be lifted and lowered, and the remaining lifters 100 cannot be lifted and lowered.

The basic operation of the lifter 100 of the present embodiment will be described below.

< The lift 100 is located at the lower level: FIG. 12-

The lifting frame 100 is held to stop at the lower position.

The upper limit switch 171 is off, and the lower limit switch 172 is on.

Since the lower limit switch 172 is turned on, the control unit 500 turns off the illuminated button 160, and the lowering operation is disabled.

< Lifting frame 100 up: FIG. 12-FIG. 13 ]

When the foot operation pedal 154 (the raising operation unit 164) is operated (the raising operation), the control unit 500 outputs a raising drive command to the corresponding raising/lowering drive unit 110 to raise the corresponding lifting/lowering rack 100.

During the ascent, limit switches 171 and 172 are turned off.

For the lifting frame 100 during the lifting, the control unit 500 turns on the illuminated button 160 to enable the lowering operation. But the illuminated button 160 of the other lifter 100 is turned off and the lowering operation cannot be performed.

During the ascent, the illuminated button 160 may be set to a different illumination state (for example, flashing) to indicate that the lift 100 is in the ascent and descent.

As the upper limit switch 171 turns on (reaches the upper position), the control unit 500 stops driving the electric motor 111, and the lifter 100 is in the stop-hold state.

< The lift 100 is located at the upper level: FIG. 13>

The lifting frame 100 is held to stop at the upper position.

The upper limit switch 171 is on, and the lower limit switch 172 is off.

When the detecting means 3 (area sensor) and the sensing means 150 (rod sensor) are turned off, the control means 500 turns on the illuminated button 160 to enable the lowering operation.

When either one of the detecting means 3 (area sensor) and the sensing means 150 (rod sensor) is turned on, the control means 500 turns off the illuminated button 160, and the lowering operation is disabled.

< Lowering of the lift 100: FIG. 13-FIG. 12 ]

When the illuminated button 160 (lowering operation unit) is operated (lowering operation), the control unit 500 outputs a lowering driving command to the corresponding lowering driving unit 110 to lower the corresponding lifting frame 100.

During the descent, limit switches 171, 172 are opened.

For the lifting frame 100 during the lowering, the control unit 500 turns on the illuminated button 160 to enable the lowering operation.

During the descent, the illuminated button 160 may be set to a different illumination state (for example, flashing) to indicate that the lift 100 is in the process of ascending and descending.

As the lower limit switch 172 turns on (reaches the lower position), the control unit 500 stops driving the electric motor 111, and the lifter 100 is in the stop-hold state.

< Detection unit 3 is on during descent of the lift 100: FIG. 14>

The control unit 500 stops driving the electric motor 111, and the lift 100 is in a stop-hold state.

The control unit 500 turns off the illuminated button 160, and makes the lowering operation impossible.

The control unit 500 sets the foot operation pedal 154 (the raising operation portion 164) to be unable to perform the raising operation.

All the lifting frames 100 except the descending lifting frame 100 remain in the stopped state (lifting prohibition state). Their illuminated buttons 160 also remain extinguished and cannot be lowered. The foot pedal 154 is also kept in a state where the ascending operation is disabled.

By returning the detection means 3 (area sensor) to off, the control means 500 turns on the illuminated button 160 to enable the lowering operation. The foot operation pedal 154 becomes also capable of a lifting operation.

< Sense unit 150 is on during descent of the lift 100: FIG. 15 ]

The control unit 500 drives the electric motor 111 upward, and lifts the lift 100.

The sensing unit 150 (rod-like sensor) becomes off (continues to rise) due to the rise of the lift 100.

By turning off the sensing means 150, the control means 500 turns on the illuminated button 160, and enables the lowering operation.

The operation of the entire upper and lower two-tier parking facility 1000 according to the present embodiment will be described below with reference to flowcharts shown in fig. 17 to 20.

As shown in fig. 17, the main control unit 501 first operates the reset switch 503 (start switch: see fig. 16), and in M0, outputs an execution instruction of the initialization control S0 to all the individual control units 502. Each individual control unit 502 that has received the execution instruction of the initialization control S0 executes the initialization control in S0.

The reset switch 503 may be a push switch or the like provided at a position within the upper and lower two-layer parking facility 1000, or may be a switch that can be remotely operated from the outside of the upper and lower two-layer parking facility 1000.

Specifically, as shown in fig. 18, each individual control unit 502 sets the lighting flag BF (green light flag) of the lighting button 160 (green light) to 0 to turn off the lighting button 160 (the corresponding lifter 100 is not shown to be lifted) in S01, sets both the lowering switch flag DF and the lifting switch flag UF to 0 to turn off the lighting button 160 constituting the lowering operation unit and the sensing unit 154 constituting the lifting operation unit in S02, and sets both the motor lowering flag MDF and the motor lifting flag MUF of the electric motor 111 to 0 to hold the lifter 100 in a stopped state in S03. Each individual control unit 502 after finishing the initialization control S0 transmits the execution result of the initialization control S0 to the main control unit 501 in S00 of fig. 17.

As shown in fig. 17, 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 instruction of the safety confirmation control S1 to all individual control units 502 in M1. The individual control unit 502 that has received the execution instruction of the safety confirmation control S1 executes the safety confirmation control in S1.

Specifically, as shown in fig. 19, each individual control unit 502 determines in S11 whether or not the detection unit 34 of the detection unit 3 (area sensor) is on. When the detection unit 34 is on, each individual control unit 502 sets the lighting flag BF (green light flag) to 0 (turn-off lighting type 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 (green light flag) to 1 in S12 to light the illuminated button 160 (can perform the lowering operation). Next, each individual control unit 502 determines in S13 whether or not the illuminated button 160 (down switch) is off. When the illuminated button 160 (down switch) is on, each individual control section 502 sets the down switch flag DF to 1 and the up switch flag UF to 0 in S14, ending the safety confirmation control. On the other hand, when the illuminated button 160 (down switch) is turned off, each individual control unit 502 sets the down switch flag DF to 0 in S15, and determines whether or not the sensing unit 153 (up switch) of the sensing unit 150 (rod sensor) is turned on in S16. When the sensing unit 153 (the rising switch) is turned on, each individual control unit 502 sets the rising switch flag UF to 1 in S17, and ends the safety confirmation control. On the other hand, when the sensing unit 153 (the rising switch) is turned off, each individual control unit 502 sets the rising switch flag UF to 0 in S18, and ends the safety confirmation control. Each individual control unit 502 after the completion of 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. 17.

As shown in fig. 17, the main control unit 501 that receives the execution result of the safety confirmation control S1 from each individual control unit 502 determines, in M2, the individual control unit 502 that either one of the two conditions that the lighting flag BF (green light flag) is 1 and the down switch flag DF is 1 or that the lighting flag BF (green light flag) is 1 and the up switch flag UF is 1 is the first, and outputs the execution instruction of the up-down drive control S2 only to the determined individual control unit 502. The individual control unit 502 that has received the execution instruction of the lift drive control S2 executes the lift drive control in S2.

Specifically, as shown in fig. 20, the individual control unit 502 that has received the execution instruction of the elevation drive control S2 first determines in S21 whether or not the lighting flag BF (green light flag) is 1 and the descent switch flag DF is 1. When the lighting flag BF (green light flag) is 1 and the lowering switch flag DF is 1, the individual control unit 502 sets the motor lowering flag MDF to 1 in S22, and causes the electric motor 111 to output a predetermined driving force for lowering the lift 100.

On the other hand, the individual control unit 502 determines in S23 whether the detection unit 34 of the detection unit 3 (area sensor) is on, and determines in S24 whether the sensing unit 153 (rising switch) of the sensing unit 150 (rod sensor) is on. As long as both are disconnected, the individual control unit 502 continues the lowering of the lift 100. When the lowering is completed after the lifter 100 reaches the predetermined lower position and the lower limit switch 172 (lower limit switch) is turned on (S25/yes), the individual control unit 502 sets the motor lowering flag MDF to 0 to stop the lowering drive of the electric motor 111, sets the lifter 100 to the stop holding state, and sets the lighting flag BF (green light flag) to 0 to turn off the illuminated button 160 in S26.

When the sensing unit 153 (the ascent switch) of the sensing unit 150 (the rod-like sensor) turns on during the descent of the lift 100, the individual control unit 502 proceeds to S28, and the lift 100 is moved from descent to ascent. The processing after S28 will be described later.

On the other hand, in S21, if the lighting flag BF (green light flag) is not 1 and the down switch flag DF is 1, the individual control unit 502 determines in S27 whether the lighting flag BF (green light flag) is 1 and the up switch flag UF is 1. When the light-up flag BF (green light flag) is 1 and the up switch flag UF is 1, the individual control unit 502 proceeds to S28.

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

In addition, the individual control unit 502 determines in S29 whether or not the detection unit 34 of the detection unit 3 (area sensor) is on, and if it is off, the lifting of the crane 100 is continued. When the lift 100 reaches the predetermined upper level and the upper limit switch 171 (upper limit switch) is turned on (S30/yes), the individual control unit 502 sets the motor up flag MUF to 0 to stop the lifting drive of the electric motor 111 in S31, sets the lift 100 to the stop holding state, and sets the lighting flag BF (green light flag) to 0 to turn off the illuminated button 160.

Incidentally, when the detection section 34 of the detection unit 3 (area sensor) becomes on during the descent (S23) or ascent (S29) of the lifter 100, the individual control section 502 sets the motor descent flag MDF and the motor ascent flag MUF to 0 to stop driving the electric motor 111 in S32, puts the lifter 100 in a stop holding state, and sets the lighting flag BF (green light flag) to 0 to turn off the illuminated button 160 (green light). In addition, the individual control unit 502 may output a predetermined alarm sound or warning sound from an alarm output unit, not shown, in S33.

On the other hand, in S27, when the lighting flag BF (green light flag) is not 1 and the up-switch flag UF is 1, the individual control unit 502 ends the up-down drive control.

The individual control unit 502 after finishing the lift drive control S2 transmits the execution result of the lift drive control S2 to the main control unit 501 in S20 of fig. 17. Each individual control unit 502 returns to S0 and executes the initialization control again.

When the detection unit 34 of the detection unit 3 (area sensor) is turned on and the crane 100 is stopped in the immediately preceding lifting drive control S2 (fig. 20), and the individual control units 502 return to S0 and execute the safety confirmation control S1 (fig. 17) again from the initialization control S0 (fig. 17), if the detection unit 34 of the detection unit 3 (area sensor) is turned off (S11/N) in the safety confirmation control S1 (fig. 19), the individual control units 502 set the lighting flag BF (green light flag) to 1 and light the lighting button 160 in S12, and the lifting operation and the lowering operation (S12) of the crane 100 being stopped can be performed. That is, in the lifting drive control S2 (fig. 20), even if the detection unit 34 of the detection unit 3 (area sensor) is turned on and the lifting frame 100 is stopped, the lifting operation and the lowering operation of the stopped lifting frame 100 can be performed as long as the self-recovery to the state in which the detection unit 34 is turned off is possible.

The first embodiment of the present utility model has been described above, but this is merely an example, and the present utility model is not limited thereto, and various modifications such as addition and omission can be made based on the knowledge of those skilled in the art without departing from the gist of the present utility model.

Hereinafter, embodiments different from the above-described embodiments and modifications of these embodiments will be described. The same reference numerals are given to the portions having functions common to those of the above embodiments, and detailed description thereof is omitted. The above-described embodiments, the following modifications, and other embodiments can be appropriately combined and implemented within a range where technical contradiction does not occur.

The fixed rails 2 may be provided two (a pair) on one side with respect to the arrangement direction (the lateral direction Y) of the struts 1. In this case, two casters 9 and 9 are provided for each carriage 200 corresponding to the two fixed rails 2 and 2. As shown in fig. 21, for example, one or two (one in fig. 21) fixing rails 2 may be provided on each side of the column of the strut 1. In fig. 21, the lifters 100 are alternately arranged apart from each other in the direction of arrangement of the struts 1 (the lateral direction Y).

Each carriage 200 may be provided with a wheel-moving carriage mounted so as to be movable from one side (rear side) to the other side (front side) in the longitudinal direction X while holding a preceding wheel (for example, front wheel) that is a wheel of the bicycle BCL that is guided from the doorway 4, and the bicycle BCL can be more easily carried into the carriage 200 by the wheel-moving carriage.

The drive source of the elevation drive unit 110 may use a hydraulic cylinder, a pneumatic cylinder, or the like instead of the electric motor 111.

The ascending and biasing force generation source of the biasing unit 120 may be a constant load spring, a weight, or the like, instead of the gas spring 121.

The detection means 3 may be a non-contact type (light, ultrasonic wave, electromagnetic wave, or the like) obstacle detection means instead of the mechanical type described above.

In the embodiment described above, in the upper and lower two-story parking facility 1000, only one of the plurality of the lifters 100 can be lifted and lowered, and the remaining lifters 100 cannot be lifted and lowered, which can also be achieved by control. In this case, the control unit 500 is configured to output a drive command only to the lift drive unit 110 corresponding to the illuminated button 160 (operation unit 162) operated first by the operator when the plurality of illuminated buttons 160 (display unit 161) simultaneously display that the operator can operate (in this case, are simultaneously lit).

Specifically, the processing of M2 in the various controls of fig. 22 is changed as follows. That is, in M2, the main control unit 501 determines the single control unit 502 that either has the first established condition that the lighting flag BF (green light flag) is 1 and the down switch flag DF is 1, or that the lighting flag BF (green light flag) is 1 and the up switch flag UF is 1, and outputs the execution instruction of the up-down drive control S2 only to the determined single control unit 502. Then, only the individual control section 502 that received the execution instruction executes the lift drive control in S2. In addition, in M3, the main control unit 501 outputs an execution instruction of the initialization control S0 to the individual control units 502 other than the individual control unit 502 that has outputted the execution instruction of the lift drive control S2. The transmission of the execution result of the lifting drive control of S20 is performed only by the individual control unit 502 that has received the execution instruction of the lifting drive control S2, and the subsequent processing is the same as in the above-described embodiment.

The up-and-down two-layer parking facility of the present utility model can be applied to outdoor parking places such as on sidewalks and in parks, indoor parking places such as in high-level apartments and public houses, and underground parking places such as buildings and subways.
