Description

  The present invention relates to a mechanical parking lot that introduces a vehicle that has entered a passenger compartment into a storage shelf, and an attachment device used in the mechanical parking lot.

  In city centers with high population density, complex commercial facilities, and housing complexes, mechanical parking lots that use multiple storage shelves to increase parking efficiency are often used. A mechanical parking lot generally includes a passenger compartment for a driver to get on or off the vehicle, and a storage shelf provided on the ground or underground. In a mechanical parking lot, a vehicle is moved between a passenger compartment and a storage shelf by a lifting device such as an elevator.

  If the vehicle parked in the passenger compartment to park in the mechanical parking lot is too large or if the vehicle is parked at a side, the vehicle may interfere with the surroundings when entering the hoistway from the passenger compartment. Therefore, an out-of-door sensor for detecting whether or not the vehicle has stopped outside the normal accommodation area is usually provided in the passenger compartment of the mechanical parking lot.

  For example, Patent Document 1 proposes that a laser sensor of a type that emits laser light and receives the reflected light is provided in the passenger compartment. This type of laser sensor is advantageous in that the protrusion can be detected on the surface as compared with the transmission type sensor.

JP 2010-255377 A

  Usually, a laser sensor as described in Patent Document 1 is attached to a passenger compartment through a bracket. Various types of brackets are provided by, for example, laser sensor vendors. Many of such brackets have an adjustment mechanism that can tilt the laser light irradiation surface. On the other hand, there is often no adjustment mechanism for the position of the irradiation surface, and it is assumed that the irradiation surface is arranged at a desired position by moving the entire laser sensor and bracket.

  For example, in an application in which a laser sensor is used as a human sensor in a factory, the position of the irradiation surface is generally not required to be so high. Therefore, the above-mentioned brackets provided by the vendor can be used sufficiently.

  However, when the laser sensor is used as a protrusion sensor in a passenger parking area of a mechanical parking lot, alignment of the irradiation surface is important, and the accuracy required for the position of the irradiation surface is relatively high. The operation of realizing such high accuracy by moving the entire laser sensor and the bracket is not easy, and it takes time to adjust the position of the irradiation surface.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a sensor mounting technique capable of shortening the time for adjusting the position of the detection surface of the protrusion sensor in a mechanical parking lot.

  One embodiment of the present invention relates to a mechanical parking lot. This mechanical parking lot is a mechanical parking lot that introduces a vehicle that has entered the passenger compartment into the storage shelf, and a first detection device that detects the protrusion of the vehicle that has entered the passenger compartment from the detection surface is to be attached. A second support portion attached to the passenger compartment, acting on the first support portion so as to be positioned within a predetermined first error range along a crossing direction in which the detection surface intersects the detection surface; By changing the relative position in the intersecting direction of the first support portion and the second support portion, the detection surface is positioned in the second error range smaller than the first error range along the intersecting direction. And a translation mechanism that translates in the crossing direction.

  According to this aspect, the detection surface can be positioned in stages.

  Another aspect of the present invention is an attachment device. This attachment device is an attachment device that is attached to an entry / exit room of a mechanical parking lot that introduces a vehicle that has entered the entrance / exit to the storage shelf, and detects a protrusion of the vehicle that has entered the entrance / exit from the detection surface. A first support portion to be attached to the passenger compartment, and a first attachment portion that acts on the first support portion so that the detection surface is positioned within a predetermined first error range along a crossing direction intersecting the detection surface. The detection surface is positioned within the second error range smaller than the first error range along the intersecting direction by changing the relative position in the intersecting direction between the two support portions and the first support portion and the second support portion. A translation mechanism that translates the detection surface in the intersecting direction.

  It should be noted that any combination of the above-described constituent elements and those obtained by replacing the constituent elements and expressions of the present invention with each other among apparatuses, methods, systems, etc. are also effective as an aspect of the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, the time of position adjustment of the detection surface of a protrusion sensor can be shortened in a mechanical parking lot.

  Hereinafter, the same or equivalent components and members shown in the respective drawings are denoted by the same reference numerals, and repeated descriptions thereof are omitted as appropriate. In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. Also, in the drawings, some of the members that are not important for describing the embodiment are omitted.

  The mechanical parking lot which concerns on embodiment introduces vehicles, such as a car which entered the passenger compartment, to a storage shelf. This mechanical parking lot has an overhang sensor that detects when a vehicle protrudes from a normal accommodation area when guiding a vehicle entering the passenger compartment and when entering a stopped vehicle. The protrusion sensor is an optical detection device that scans the detection surface with a laser beam and receives reflected light from a portion of the vehicle protruding from the detection surface. The protrusion sensor is attached to a predetermined position in the passenger compartment through a bracket, that is, an attachment device.

  The bracket intersects a part of the passenger compartment, for example, a passenger compartment side support plate attached to the frame, a sensor side support plate to which the protrusion sensor is attached, and a detection surface of the passenger compartment side support plate and the sensor side support plate. A push-bolt type parallel movement mechanism that changes a relative position in a direction, for example, an orthogonal direction orthogonal to the detection surface. When the worker positions the detection surface so as to coincide with, for example, the boundary surface of the accommodation area at the time of installation or maintenance of the mechanical parking lot, the worker first attaches the passenger compartment support plate to the passenger compartment frame. At this time, the operator loosens or tightens the fastening means such as bolts and nuts that secure the frame and the passenger compartment side support plate, thereby moving the overhang sensor and the entire bracket with respect to the frame to roughly position the detection surface. To do.

  Next, the operator finely adjusts the position of the detection surface in the orthogonal direction by moving the sensor-side support plate along the orthogonal direction with respect to the passenger compartment support plate using the push bolt of the parallel movement mechanism. By enabling two-stage adjustment of coarse adjustment and fine adjustment in this way, alignment in the orthogonal direction of the detection surface becomes easier and work time can be shortened. According to the test conducted by the present inventors, when the bracket according to the embodiment was not used, it took 2 to 3 hours to align the detection surface of one protrusion sensor, but the bracket according to the embodiment was used. In this case, the time required for alignment was 20 to 30 minutes.

  FIG. 1 is a front view of a mechanical parking lot 10 according to an embodiment. FIG. 2 is a plan view of the 2F storage shelf 14.

The four masts 90, the lifting device 94, the left protrusion sensor 36, the right protrusion sensor 38, and the bracket 46 are provided. The left protrusion sensor 36, the right protrusion sensor 38, and the bracket 46 will be described later with reference to FIG.

  The pallet 32 is a flat plate member, and the upper surface on which the vehicle is mounted, that is, the vehicle mounting surface is substantially rectangular. The mechanical parking lot 10 is a pallet type parking lot using a pallet 32. The pallet-type mechanical parking lot 10 uses a lifting device 94 to lift and lower the pallet 32 on which the vehicle 20 is mounted, or uses the first transfer device 56 and the second transfer device 58. The vehicle 20 is parked on the storage shelf by moving the pallet 32 in the surface direction.

  Each of the 2F storage shelf 14, the 3F storage shelf 16, and the 4F storage shelf 18 includes 10 parking spaces. These ten parking spaces are arranged in a matrix of 5 rows and 2 columns when viewed in plan. Each parking space is configured to accommodate the pallet 32. The parking space is one parking area (one unit of parking) in the parking room where the vehicle 20 can be parked together with the pallet.

  The boarding / alighting room 12 is provided on the first floor of the building 24. The passenger compartment 12 is provided at the lower end of the hoistway 96, that is, on the ground surface side. The passenger compartment 12 and the hoistway 96 are connected via a communication hole 26 that is large enough to allow the pallet 32 to pass therethrough. The hoistway 96 is provided along the vertical direction (z direction in the figure). The hoistway 96 communicates with each of the 2F storage shelf 14, the 3F storage shelf 16, and the 4F storage shelf 18. Therefore, each storage shelf and the passenger compartment are connected by the hoistway 96.

  When viewed in plan, the substantially rectangular lift frame 88 is supported by the four masts 90 so as to be movable up and down. A first transfer device 56 is mounted on the upper part of the lift frame 88. The lifting device 94 is installed under the floor of the passenger compartment 12 and lifts the lift frame 88 along the hoistway 96. The lift frame 88, the four masts 90, and the lifting device 94 include four lift frames described in Japanese Patent Application Laid-Open Nos. 2009-197417 and 2008-261159 previously filed by the present applicant. The mast and the lifting device can be applied respectively.

  A pallet 32 is mounted on the top of the first transfer device 56. The first transfer device 56 is configured to be able to move the pallet 32 in one direction (the x direction in the figure). The second transfer device 58 is provided in each parking space, and moves the pallet 32 in the x direction and the y direction across the parking space. The y direction is a direction orthogonal to both the x direction and the z direction. A fall prevention roller 38 is installed between the parking space and the parking space to support the pallet 32 when the pallet 32 moves across the parking space. For example, a transport device described in Japanese Patent Publication No. 7-29681 filed earlier by the present applicant can be applied to the second transfer device 58.

  FIG. 3 is a plan view of the passenger compartment 12. 4 is a cross-sectional perspective view taken along line AA of FIG. In order to make the description clearer, the display of the mast 90, the first transfer device 56, the lift frame 88, and the lifting device 94 is omitted in FIGS. FIG. 3 shows a state in which the pallet 32 is called into the passenger compartment 12 before the vehicle enters the passenger compartment 12. The passenger compartment 12 is substantially rectangular in plan view, and hereinafter, the x direction is the left-right direction and the y direction is the front-rear direction. The front-rear direction is a direction in which the vehicle 20 enters the passenger compartment 12 from the outside.

  The sensor frame 34 is a square pipe extending in the left-right direction, and one end is fixed to the left wall of the passenger compartment 12 and the other end is fixed to the right wall of the passenger compartment 12. The sensor frame 34 is provided on the side opposite to the vehicle entrance 44 of the passenger compartment 12 and on the ceiling side. The left protrusion sensor 36 is attached to the sensor frame 34 via a bracket 46. The right protrusion sensor 38 is attached to the sensor frame 34 via a bracket (not shown) similar to the bracket 46.

  The left protrusion sensor 36 is an optical detection device that detects the protrusion of the vehicle 20 that has entered the passenger compartment 12 from the left detection surface 50, a light projecting unit (not shown) that emits laser light of a predetermined wavelength, and its wavelength. A light receiving unit (not shown) configured to detect light of an equivalent wavelength. The light projecting section emits laser light in the left detection surface 50 parallel to the yz plane. The light projecting unit scans the entire left detection surface 50 with the laser light by rotating the path of the laser light around the x axis. The left detection surface 50 is provided along the left end of the pallet 32. The orthogonal direction orthogonal to the left detection surface 50 is the left-right direction.

  Consider a case in which a part of the vehicle 20 that enters the passenger compartment 12 and stops on the pallet 32 protrudes from the left detection surface 50, that is, crosses the left detection surface 50. The light projecting portion of the left protrusion sensor 36 scans the left detection surface 50 with laser light. A part of such laser light is reflected by a part of the vehicle 20 that protrudes. Part of the reflected laser light returns to the left protrusion sensor 36. The light receiving part of the left protrusion sensor 36 detects the reflected light returning in this way, and the left protrusion sensor 36 transmits a detection result to a control device (not shown). The control device may limit movement of the vehicle from the passenger compartment 12 to the storage shelf when the left protrusion sensor 36 detects reflected light.

  The right protrusion sensor 38 is configured in the same manner as the left protrusion sensor 36. A region sandwiched between the left detection surface 50 of the left protrusion sensor 36 and the right detection surface 64 of the right protrusion sensor 38 is an accommodation region 48. In other words, the storage area 48 is set based on the size of the pallet 32. The left detection surface 50 is positioned by the bracket 46 so as to form the left side surface of the accommodation region 48. By a similar bracket (not shown), the right detection surface 64 is positioned to form the right side surface of the receiving area 48. In order to prevent the vehicle 20 from protruding more reliably, the accommodation area 48 may be set smaller than the size of the pallet 32.

The sixth bolt 146 is screwed into the screw hole of the first bolt seat 142. By tightening the tenth nut 148 against the first bolt seat 142, the position of the sixth bolt 146 in the front-rear direction is fixed. The same applies to the seventh bolt 150, the eleventh nut 152, and the second bolt seat 144.

  The first flat head screw 206 and the second flat head screw 208 respectively fix the first protrusion 160 and the second protrusion 190 to the left and right of the surface of the plate portion 108a opposite to the left protrusion sensor 36 by screwing. The first protrusion 160 and the second protrusion 190 are both washers. The first protrusion 160 and the second protrusion 190 are fitted in the first guide groove 162 and the second guide groove 188 of the first intermediate plate 106 so as to be slidable in the left-right direction. The first protrusion 160 abuts against the screw tip of the fifth bolt 140 together with the right side surface 108 b of the second intermediate plate 108. The second protrusion 190 contacts the screw tip of the fourteenth bolt 192 together with the left side surface of the second intermediate plate 108.

  The sensor-side support plate 110 includes a plate portion 110a, a bolt contact portion 110b provided on the right side of the plate portion 110a, and a screw shaft 166 erected in the vertical direction substantially at the center of the plate portion 110a.

  One end of the screw shaft 166 is fixed to the plate portion 110a by welding, and the other end side is loosely fitted in an opening (not shown) provided at substantially the center of the second intermediate plate 108. By tightening or loosening the thirteenth nut 164 that is screwed onto the screw shaft 166, the sensor-side support plate 110 may be fixed to the second intermediate plate 108 or rotated around the screw shaft 166. it can. In particular, when the thirteenth nut 164 is tightened with a predetermined torque, the second intermediate plate 108 and the sensor-side support plate 110 are temporarily fixed. In this temporarily fixed state, the sensor side support plate 110 is fixed to the second intermediate plate 108 unless the sixth bolt 146 and the seventh bolt 150 that are push bolts are turned. When the sixth bolt 146 and the seventh bolt 150 are turned, the sensor side support plate 110 rotates around the screw shaft 166 with respect to the second intermediate plate 108.

Screwed together. The same applies to the fifteenth opening 238 and the sixteenth opening 240 provided in the plate portion 110a of the sensor side support plate 110. The left protrusion sensor 36 is attached to the sensor side support plate 110 by four bolts including the tenth bolt 176 and the eleventh bolt 178.

  When positioning the left detection surface 50 along the left-right direction, the operator first loosens the first fastening means and the second fastening means, and moves the left protrusion sensor 36 and the entire bracket 46 along the sensor frame 34. When the operator determines that the left detection surface 50 is adjusted to a desired position in the left-right direction, the first fastening means and the second fastening means are fastened, and the left protrusion sensor 36 and the entire bracket 46 are fixed to the sensor frame 34. To do. Here, since the operator directly moves the entire left protrusion sensor 36 and the bracket 46 by hand, the positioning accuracy is not high, and the left detection surface 50 is within a relatively large first error range from a desired position. That is, at this stage, even if the error is relatively large, it is allowed, so that the work can be advanced quickly.

  Next, the operator temporarily fixes the second intermediate plate 108 to the first intermediate plate 106 by tightening four nuts including the twelfth nut 158 and the eighteenth nut 186 with a predetermined torque. The operator changes the relative position in the left-right direction between the second intermediate plate 108 and the first intermediate plate 106 in the temporarily fixed state by turning the fifth bolt 140 and the fourteenth bolt 192. When this relative position changes, the left detection surface 50 translates in the left-right direction. When the operator determines that the left detection surface 50 is adjusted to a desired position in the left-right direction by such parallel movement, the operator tightens the four nuts including the twelfth nut 158 and the eighteenth nut 186 to tighten the second intermediate plate 108. Is fixed to the first intermediate plate 106. Since the positioning of the left detection surface 50 here is performed by a push bolt method, the positioning accuracy is higher than when the operator moves it directly by hand. That is, the left detection surface 50 is within the second error range smaller than the first error range from the desired position.

  From the viewpoint of positioning the left detection surface 50 along the left-right direction, the second intermediate plate 108 and the sensor-side support plate 110 may be combined to serve as a first support portion to which the left protrusion sensor 36 should be attached. The loading / unloading chamber side support plate 104 and the first intermediate plate 106 are attached to the loading / unloading chamber 12 that acts on the first support portion so that the left detection surface 50 is positioned within the first error range along the left-right direction. It is good also as a 2nd support part. First intermediate plate 106, fifth bolt 140, ninth nut 138, first protrusion 160, fourteenth bolt 192, nineteenth nut 194, second protrusion 190, eighth bolt 156, twelfth nut 158, thirteenth By combining the bolt 184 and the 18th nut 186 and changing the relative position in the left-right direction of the first support portion and the second support portion, the left detection surface 50 is within the second error range along the left-right direction. A translation mechanism that translates the left detection surface 50 in the left-right direction so as to be positioned may be used. In this case, the eighth bolt 156, the twelfth nut 158, the thirteenth bolt 184, the eighteenth nut 186, and the first intermediate plate 106 are combined to temporarily fix the first support portion to the second support portion. It is good. In addition, the fifth bolt 140, the ninth nut 138, the first projecting portion 160, the fourteenth bolt 192, the nineteenth nut 194, and the second projecting portion 190 are combined, and the first is temporarily fixed by the temporary fixing portion. It is good also as a moving part which moves a support part along the left-right direction with respect to a 2nd support part.

  When positioning the left detection surface 50 along the vertical direction, a fourth nut 126 and a fifth nut 128 that are screwed to the third bolt 122, and a seventh nut 134 and an eighth nut that are screwed to the fourth bolt 130. 136, the 15th nut 172 and the 16th nut 174 screwed to the ninth bolt 168, and the same two nuts screwed to the 18th bolt 204 are shifted by the same amount, so that the first intermediate The plate 106 is translated in the vertical direction.

  When the left detection surface 50 is positioned around an axis along the left-right direction or the front-rear direction, the fourth nut 126, the fifth nut 128, and the fourth bolt 130 screwed to the third bolt 122 are screwed. 7 nut 134 and 8th nut 136, 15th nut 172 and 16th nut 174 screwed to 9th bolt 168, and the same two nuts screwed to 18th bolt 204 by different amounts By shifting, the first intermediate plate 106 is rotated around an axis along the left-right direction or the front-rear direction.

  When positioning the left detection surface 50 about the axis along the vertical direction, the operator temporarily fixes the sensor-side support plate 110 to the second intermediate plate 108 by tightening the thirteenth nut 164 with a predetermined torque. . The operator rotates the sensor-side support plate 110 in the temporarily fixed state by rotating the sixth bolt 146 and the seventh bolt 150 around the screw shaft 166 with respect to the second intermediate plate 108. When the sensor-side support plate 110 rotates in this way, the left detection surface 50 also rotates around the screw shaft 166. When the operator determines that the left detection surface 50 is adjusted to a desired angular position around the screw shaft 166 by such rotation, the 13th nut 164 is tightened and the sensor side support plate 110 is moved to the second intermediate plate 108. Fix against.

  FIG. 11 is an explanatory diagram for explaining positioning of the left detection surface 50 along the left-right direction. FIG. 11 corresponds to the case where the left detection surface 50 is viewed from the vertical direction. A solid line indicates the left detection surface 50, and a broken line indicates a desired position 70 in the left-right direction (x direction) of the left detection surface 50. The distance between the broken line and the two-dot chain line indicates the first error range 72, and the distance between the broken line and the one-dot chain line indicates the second error range 74.

Operation | movement of the mechanical parking lot 10 comprised as mentioned above is demonstrated.
When the vehicle 20 enters the mechanical parking lot 10, the driver or the clerk stops the vehicle 20 on the pallet 32 called in the passenger compartment 12. The driver or the clerk gets off after stopping, and inputs an entry instruction to a control device (not shown) provided in the passenger compartment 12. Here, the left protrusion sensor 36 and the right protrusion sensor 38 are used until the vehicle 20 enters the vehicle entrance 44 and stops on the pallet 32, and after the warehousing instruction is issued until the pallet 32 actually starts moving. In the meantime, when the light receiving unit detects the reflected light, a signal for notifying the protrusion is transmitted to the control device. When the control device receives such a signal, the control device warns the driver or the staff through the display means such as a vehicle guide light.

  According to the mechanical parking lot 10 according to the present embodiment, in addition to the adjustment by moving the left protrusion sensor 36 and the entire bracket 46, the left side detection surface 50 of the left protrusion sensor 36 is positioned in the left-right direction. Adjustment is also performed by changing the relative position of the plate 110 and the passenger compartment support plate 104 in the left-right direction. The accuracy of the latter adjustment is higher than the accuracy of the former adjustment. Thus, by introducing the positioning mechanism by the relative motion between the members of the bracket 46, the left detection surface 50 can be positioned more easily and accurately in a short time.

  Further, in the mechanical parking lot 10 according to the present embodiment, in addition to the position adjustment of the left detection surface 50, the angle of the left detection surface 50 around the three axes can be finely adjusted. Thereby, the freedom degree of adjustment of the left detection surface 50 by the bracket 46 increases.

  The configuration and operation of the mechanical parking lot 10 according to the embodiment have been described above.
