Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical multi-level parking lot.

0002

[Prior Art] A mechanical multi-level parking lot in which cars are transferred between the parking room and the transport machine by exchanging pallets between the parking space and the transport machine is disclosed in Japanese Patent Application Laid-Open No. 140369/1999.
and JP-A-55-111570.

In Japanese Patent Application Laid-Open No. 2-140369, as shown in FIG.
9. A plurality of pallet traversing rollers are arranged in two upper and lower stages 2A and 2B, which are configured to have a length spanning the entire width of the pallet 105, and have the function of supporting the pallet 105 and horizontally traversing the pallet by rotating. . Further, the pallet traversing roller is configured to be able to move back and forth in the axial direction, and when protruding, it can hold the pallet 105 and can traverse the pallet 105.

[0004] Pallet exchange between the carrier 101 and the parking room 109 involves scooping up the pallet in the parking room using the carrier, exchanging the pallet with the pallet in the hoistway on the carrier, and then moving the pallet from above when the carrier lowers. This is done by leaving the pallet that was in the hoistway in the parking lot.

In Japanese Patent Application Laid-Open No. 55-111570, as shown in FIG. 19, a shelf 107b for empty pallets 105b is provided below the parking room 109, and when entering the warehouse, a pallet 105a on which a car is placed is transported by a carrier 101. Insert it into parking lot 109,
After that, the carrier 101 is moved to the empty pallet shelf 107b under the parking room.
The empty pallet 105b on the shelf is taken out to the carrier side, thereby replacing the pallet. When leaving the warehouse, the opposite operation is performed.

[0006] Next, there is Japanese Patent Application Laid-Open No. 55-23207 regarding a pallet turning method. As shown in FIG. 20, this system is equipped with a push-up device 115c for lifting a rotating frame 115d at the entrance/exit of the parking lot, and a pallet 105 for loading a vehicle can be placed in the vehicle storage cage in a rotatable and removable manner. It was placed in And at the parking lot entrance,
The revolving frame is raised and the pallet for loading the vehicle in the vehicle storage cage is delivered to the revolving frame to perform the revolving.

[0007]

[Problem to be solved by the invention] The above-mentioned Japanese Patent Application Laid-Open No. 2-14
In 0369, it is necessary to provide an advance/retreat drive device for the pallet traversing roller, which is the pallet support part, on the carrier.
The structure of the carrier becomes complicated and the weight of the carrier increases.

[0008] Furthermore, since the pallet traversing roller, which is a pallet support portion, is provided on a long carrier extending between the left and right parking rooms, the weight of the carrier becomes even greater. Therefore, the electric power required to drive the lift up and down becomes large, which is not economical.

Furthermore, because the shape of the carrier is long enough to span the left and right parking spaces, and in order to ensure horizontal movement space for the pallets, the pallets are held in the parking spaces using a cantilever-like structure from the opposite side of the parking space. This requires a holding method, which increases the structural weight and is not economical.

[0010] In the parking room, the pallet is lifted once by a carrier and then replaced, so not only the height of the car and the space for two pallets, but also the height to lift once is required for each parking room. , which reduces the vertical accommodation efficiency. Furthermore, in Japanese Patent Laid-Open No. 55-111570, when exchanging pallets, the transfer of a real pallet and the transfer of an empty pallet are carried out separately, which takes time.

Furthermore, in Japanese Patent Application Laid-Open No. 55-23207, a pushing device is required to lift the pallet on which the car is placed when the pallet turns as the car changes direction, and a large driving force is required for the pushing up drive. It becomes necessary.

The present invention was made in order to solve the above-mentioned problems, and it is not necessary for the carrier to span the entire length of the parking room, and there is no need for the carrier to move the pallet support section on the carrier back and forth. To be configured without installing a drive unit on the carrier, to eliminate the need for vertical movement within the parking room when transferring pallets between the parking room and the carrier, and to enable empty pallets and real pallets to be exchanged alternately at the same time. Another object of the present invention is to provide a mechanical multi-story parking lot that requires less driving force to lift a pallet when changing the direction of a car.

[0013]

[Means for Solving the Problems] The mechanical multi-story parking lot of the present invention includes a carrier that is driven up and down in a hoistway provided vertically from the parking lot entrance and exit, and a plurality of floors on both sides of the hoistway. It is a mechanical multilevel parking lot that consists of a parking room and a parking lot where cars are parked on pallets.When a car is parked, the pallet on the carrier carrying the car is exchanged with an empty pallet in the parking room. In a mechanical multi-level parking lot, where the pallet in the parking room containing the car can be exchanged with the empty pallet on the carrier when the car leaves the parking lot,

001
4] The parking room is provided with pallet storage units in two levels, upper and lower, and the carrier is configured with a pair of carrier bodies installed facing each other, and pallet support units are built into these carrier bodies in two levels, upper and lower. , and horizontally transporting the pallet supported by the support part of the carrier to the storage part of the parking room by gripping the gripped part provided at the end of the pallet on the carrier, and vice versa. A horizontal transfer means for horizontally transferring the pallets stored in the storage section of the parking lot to the support section of the carrier is installed in two stages, upper and lower, and is further installed at the parking lot entrance while the carrier is stopped at the parking lot entrance. The present invention is characterized in that a pallet vertical movement means is provided for moving the pallet on the upper pallet support part of the carrier to the lower stage and the pallet on the lower stage pallet support part to the upper stage. In addition, the pallet mounting section is movable up and down, and a pallet turning means is provided at the entrance/exit of the parking lot to turn the pallet on which the car is placed.

[0015]

[Operation] The upper and lower two pallet storage areas in each parking room are designed so that the upper side is used for pallets loaded with cars and the lower side is used for empty pallets, so that pallets are always stored in only one of the upper and lower sides. . In addition, the support parts of the upper and lower stages of the carrier are
The upper side is used for pallets loaded with cars, and the lower side is used exclusively for empty pallets, so that when the carrier is raised or lowered, pallets are loaded only on either the upper or lower side. Then, after the independent operation of warehousing or warehousing is completed, the pallet in the carrier is supported by the upper support portion and placed in a standby state. In addition, if the direction of the vehicle is to be changed when entering or exiting the warehouse, a pallet turning means that moves up and down is provided underground at the parking lot entrance/exit portion of the hoistway.

[0016] In the case of parking, the vehicle drives onto the pallet that is in a standby state supported by the upper support part of the carrier at the parking lot entrance. The table is raised to the position of the pallet supported by the upper support part of the carrier and stopped. Next, the carrier is lowered to a position where it will not interfere with the rotation of the pallet, stopped, and the turntable is rotated.
Turn the car 180 degrees. Next, the carrier is raised, and after the pallet is transferred from the turntable to the upper support portion of the carrier, it is raised to the parking room position. On the other hand, in a parking lot that does not have a pallet turning means, after a car enters the parking lot, the carrier is raised to the position of the parking room where the vehicle is to be parked and then stopped.

Next, the upper horizontal transfer means grabs the gripped portion of the pallet and transfers the pallet loaded with cars to the upper storage section of the parking room for storage, and at the same time, the lower horizontal transfer means transfers the pallet loaded with cars to the upper storage section of the parking room. The grasped portion of an empty pallet stored in the lower storage section of the carrier is grasped and transferred to the lower support section of the carrier for support. In this way, the upper and lower pallets are horizontally moved simultaneously during loading and unloading.

In this state, the carrier is lowered to the parking lot entrance and stopped. Then, the empty pallet supported by the lower support part of the carrier is supported by the upper support part of the carrier by the pallet up-and-down moving means, and placed in a standby state.

On the other hand, in the case of leaving the warehouse, the empty pallet supported by the upper support part of the carrier in a standby state is supported by the pallet up/down moving means to the lower support part of the carrier, and the empty pallet is moved to the parking room at the destination. Raise to position and stop.

Next, the upper horizontal transfer means grabs the gripped portion of the pallet on which the car is loaded and is stored in the upper storage section of the parking room, and transfers it to the upper support section of the carrier to support it;
Further, the lower horizontal transfer means grasps the gripped portion of the empty pallet supported by the lower support portion of the carrier and transfers it to the lower storage portion of the parking room and stores it therein. In this state, the carrier is lowered to the entrance/exit of the parking lot, stopped, and the car is taken out. here,
The direction of the vehicle can be changed by the pallet turning means not when the vehicle enters the warehouse but when the vehicle leaves the warehouse.

[0021]

[Embodiment] First, an outline of the mechanical multi-level parking lot of the present invention will be explained with reference to FIGS. 1 and 2.

The mechanical multilevel parking lot of the present invention includes a carrier 1 that is driven up and down in a hoistway 11 provided vertically from a parking lot entrance/exit portion 12, and a plurality of floors provided on both sides of the hoistway 11. The parking lot 9 is configured to have a parking lot 9 and a parking lot 9, in which cars are placed on pallets 5 and parked. In the standby state, the pallet 5 is supported by the upper support portion of the carrier, and the carrier is stopped at a position where a car can enter at the entrance/exit of the parking lot, and the pallet 5 is in the standby state.

[0023] In addition, if the direction of the car is to be changed when entering or exiting the garage, the parking lot entrance/exit section 1 of the hoistway 11 may be used.
Pallet rotating means 1 (to be described later) that moves up and down underground in No. 2

[0024] Pallet storage sections 10a, 1 are provided in the parking lot 9.
0b are provided in two stages, upper and lower. Further, the carrier 1 is configured with a pair of carrier bodies 1A facing each other, and pallet supporting parts 7a and 7b are built into these carrier bodies 1A in two stages, upper and lower (FIGS. 3 and 4). . Then, the carrier 1 grabs the grasped portion 5c provided at the end of the pallet 5 (FIG. 5), and the pallet 5 supported by the support portion 7 of the carrier is stored in the parking room. A horizontal transfer means 2 for horizontally transferring the pallet 5 stored in the storage section 10 of the parking room to the support section 7 of the carrier is incorporated in two upper and lower stages 2A and 2B. .

In the upper and lower pallet storage sections of each parking room 9, the upper side 10a is used for pallets 5a loaded with cars, and the lower side 10b is used for empty pallets 5b. Keep it stored. In addition, the upper and lower two supporting parts of the carrier 1 are arranged such that the upper side 7a is a pallet 5a loaded with cars, and the lower side 7b is an empty pallet 5b.
It is used so that the pallet 5 is placed only on either the upper or lower side when the carrier 1 is raised or lowered.

[0026] In the case of parking, the parking lot entrance/exit section 12
, the pallet 5 supported by the upper support part 7a of the carrier

The grasped portion of the empty pallet 5b stored in the pallet 5b is grabbed and transferred to the lower support part 7b of the carrier and supported. In this state, the carrier 1 is lowered to the parking lot entrance/exit section 12. Then, the empty pallet 5 supported by the lower support part 7b of the carrier
b is supported on the upper support portion 7a of the carrier by a pallet vertical moving means 8 (described later) and placed in a standby state.

On the other hand, in the case of unloading, the empty pallet 5b supported by the upper support part 7a of the carrier 1 in the standby position is moved to the lower support part 7b of the carrier by the pallet vertical movement means 8. Support it and raise it to the 9th position of the parking lot where you will exit.
make it stop.

Next, the upper horizontal transfer means 2A grabs the gripped portion of the pallet 5a loaded with cars and stored in the upper storage section 10a of the parking room, and transfers it to the upper support section 7a of the carrier for support. Also, the empty pallet 5 supported by the lower horizontal transfer means 2B on the lower support part 7b of the carrier
The gripped portion b is grabbed and transferred to and stored in the lower storage section 10b of the parking room. In this state, move the carrier 1 to the parking lot entrance/exit area 1.
2, stop, and leave the car. Above, we showed an example of changing direction of the car when entering the parking lot, but when leaving the parking lot,
You can also turn the car around. The details of the configuration of each part will be explained below.

First, in the parking room 9, upper and lower pallet storage sections 10a and 10b are provided over almost the entire length of the parking room (FIGS. 2 and 3). The ends of the upper and lower storage sections 10a and 10b are supported by guide rails 4 of the carrier or nearby structural members and pillars 14 of the building. Therefore, it does not have a so-called cantilever structure, and the structural weight can be reduced, which is economical.

Next, the configuration of the carrier 1 will be explained. The carrier 1 is composed of a pair of carrier bodies 1A that are provided facing each other (FIG. 3). The carrier body 1A is suspended by a wire rope or chain 3, guided by a guide member 4 so as not to move horizontally, and driven up and down within the hoistway 11. Furthermore, in this example, the pair of carrier bodies 1A are driven up and down, respectively, but the pair of carrier bodies 1A are connected to each other by a horizontal member so that they can be driven up and down as a unit. You can. Carrier body 1A
Pallet support parts 7a and 7b are incorporated in two stages, upper and lower.

Next, the pallet horizontal transfer means 2, as shown in FIG. 5, grips grasped parts 5c protruding from both ends of the pallet 5 with gripping parts 6 to horizontally transfer the pallet 5. A gripping part 6 for gripping the above-mentioned gripped part 5c is incorporated into the carrier so as to be horizontally movable.

The horizontal transfer means 2 is provided in two stages, upper and lower, with a pallet 2A supported and stored on the upper side and a pallet 2B supported and stored on the lower side, but the structure is the same for the upper and lower. It is.

The gripping portion 6 can be stored within the carrier 1A and can be moved horizontally even in that state. Thereby, even if the pallet 5 is supported within the carrier 1, the gripping part 6 can be moved horizontally without interfering with the gripped part 5c of the pallet and the pallet support roller.

FIG. 5 shows the position of the gripping portion 6 when the pallet is transferred between the carrier 1 and the parking room 9. This figure shows the state in which the parking lot 9 on the right side is put into storage, where the pallet 5a on which a car is placed is supported on the upper support part 7a of the carrier 1, and the empty pallet 5b is placed in the lower storage part 10b of the parking room. Supported.

The upper grip part 6A grips the gripped part 5c at the left end of the pallet, and the lower grip part 6B also grips the gripped part 5c at the left end of the pallet, and mutually move in the direction of the arrow. The pallet 5 is transferred horizontally. In case of goods issue,
The reverse action causes horizontal transfer. Furthermore, when entering and exiting the parking lot on the left side, the positions of the gripping portions 6 that grip the gripped portions 5c of the pallet are opposite to each other. In addition, when the carrier is moved up and down, the gripping part 6 that grips the pallet in the parking room is stored inside the carrier. Next, the pallet turning means 15 is shown in FIG. This is installed when the direction of the vehicle is changed when entering or exiting the garage.

The pallet turning means 15 is installed in the underground part of the parking lot entrance/exit part 12 of the hoistway 11, and is made up of a turntable 15a on which a pallet is placed, and a turning lift drive part 15b that raises/lowers and rotates the turntable. configured. The movement of the pallet turning means 15 when changing the direction of the car 13 at the time of storage will be explained. At the parking lot entrance/exit section 12, the car 13 is driven onto the pallet 5 on the carrier that is in a standby state (a).

Next, the turntable 15a of the pallet turning means 15 is raised by the turning lift drive part 15b to the position of the pallet supported by the upper support part 7a of the carrier, and then stopped (b).

Subsequently, the carrier 1 is lowered to a position where it will not interfere with the pallet 5 even if it turns, and then stopped. Then, the turntable is turned to change the direction of the car by 180 degrees (c).

Next, the carrier 1 is raised, the pallet is transferred from the turntable 15a to the upper support portion 7a of the carrier, and the pallet is lifted to the parking lot 9 position where it is to be stored. On the other hand, after delivering the pallet 5 to the carrier 1, the turntable 15a descends and stops.

[0041] In this way, when the direction of the car is changed, the carrier is lowered and the pallet is rotated, so there is no need to raise the pallet on which the car is mounted using the lifting device of the turning means, and only the empty pallet can be raised. Therefore, the driving force of the lifting device of the turning means can be reduced.

Next, the pallet vertical moving means 8 will be explained. This pallet up/down moving means 8 is installed in a part corresponding to the parking room on the general floor, beside the hoistway at the parking lot entrance/exit part.

First, the first example is shown in FIG. A pallet support portion 8a is provided in a pair of frames 8c similar to the carrier.
, 8b are provided in two stages, upper and lower, respectively, and the upper support part 8
A is provided so as to be able to move forward and backward toward the inside of the parking room. These frames 8c are each driven up and down by cylinders 8d. Further, a pedestal 8e is provided between the pair of frames to temporarily place the pallet 5. And upper and lower pallet support parts 8
One pallet 5 is always placed on either a or 8b, and in a standby state, the pallet is supported by the lower support portion 8b. The movement of this pallet vertical moving means 8 will be explained with reference to FIG.

When moving the pallet 5 supported by the lower support part 8b, which is in the standby position, to the upper support part 8a, first, the upper support part 8a is pulled into the frame 8c, and the frame 8c is lowered. The pallet 5 is placed on the pedestal 8e and stopped at a position where the upper support portion 8a is slightly below the lower surface of the pallet 5 (a).

Next, the upper support part 8a is extended toward the parking room, and in this state, the frame 8c is raised, and the upper support part 8a is extended toward the parking room.
A supports the pallet 5, and the frame is stopped at the raised position (b).

Next, when moving the pallet 5 supported by the upper support part 8a to the lower support part 8b, first,
The frame 8c is lowered, the pallet 5 is placed on the pedestal 8e, and the frame 8c is stopped. Next, the upper support portion 8a is attached to the frame 8c.
The frame 8c is raised, the pallet 5 is supported by the lower support part 8b, and the frame is stopped at the raised position. Finally, the upper support portion 8a is extended toward the parking room.

Here, the frame rising fixed position means that the pallet in the carrier 1 and the pallet in the vertical moving means are at the parking lot entrance 12, and the upper side is the upper side and the lower side is the lower side. The side is the position where it can be transferred at the bottom. Next, a second example of the pallet vertical moving means 8 will be explained with reference to FIG. In this example, the pallet 5 is directly raised and lowered by the cylinder 8d, the frame 8c is fixed, and the frame is omitted, and has the same function as the first example. (a) shows a state in which the pallet 5 is supported by the lower support portion 8b, and (b) shows a state in which the pallet 5 is supported by the cylinder 8d. Next, a third example of the pallet vertical moving means 8 will be explained with reference to FIG.

[0048] This is a structure in which the pallet support part 8f is raised and lowered directly by the cylinder 8d. First, the pallet is transferred by the horizontal transfer means 2 to the carrier at either the upper or lower position, and then, at the other position, the pallet is transferred from the carrier by the horizontal transfer means 2 and supported by the pallet support section 8f. . Next, a fourth example of the pallet vertical moving means 8 is shown in FIG.
1 to 13 will be explained.

[0049] In this case, the upper and lower pallet supporting parts 8a
, 8b are divided, and the pallet support roller portion 5d
The support part supporting the and the adjacent support part are connected,
The structure allows the pallet on the support stand to be moved up and down by rotating while maintaining a horizontal plane, and the left and right rotating parts rotate in opposite directions in synchronization.

Next, referring to FIGS. 14 and 15, a structure in which the pallet rotating means 15 is provided with the function of the pallet vertically moving means 8 will be explained. Therefore, in this case, there is no need to provide a means for moving the pallet up and down next to the hoistway 11 at the parking lot entrance/exit section 12.

In this example, the upper pointing part 7a of the pallet of the carrier 1 is provided so as to be movable toward the inside of the hoistway 11, and the means 16 for driving the pallet back and forth is provided in the parking lot entrance/exit part 12.

The advancing/retracting driving means 16 has a structure as shown in FIG. 17, and a hook fitting 16a provided on the ground side is hooked into a hole 16f in the upper support portion of the pallet of the carrier, and the upper support is supported by a cylinder 16d. drive the parts forward and backward. cylinder 16
The cylinder 16c and the hook fitting 16a are installed in the slide frame 16b. Slide frame 1
6b is guided by a slide rail 16e and driven forward and backward by a cylinder 16d. This advance/retreat drive means 16
is stored in the underground part of the parking lot entrance/exit section 12 (a) when the carrier 1 moves up and down. The operation of this example will be explained with reference to FIG.

Pallet 5 on lower support part 7b of carrier 1
(a) When moving the upper support part 7a of the carrier 1 to the upper support part 7a, the upper support part 7a of the carrier 1 is retracted into the carrier 1 by the advancing/retreating drive means 16 to a position where it does not interfere with the pallet 5, and the upper support part 7a of the carrier 1 is moved by the turning lift means 15b. The table 15a is raised and the pallet 5 is transferred from the lower support part 7b of the carrier 1 to the turntable (b). Next, extend the upper support part 7a of the carrier,
Bring the pallet into a state where it can be supported (c). Finally, the turntable 15a is lowered and the pallet 5 is transferred from the turntable 15a to the upper support section 7a.

[0054] Moving the pallet 5 on the upper support part 7a of the carrier to the lower support part 7b is also carried out in the same way by raising and lowering the turntable 15 and moving the upper support part 7a of the carrier forward and backward. . Further, the direction change of the vehicle is performed in the same manner as in the case of FIG.

In addition, the standby state can be changed to a state where the pallet 5 is not supported by the carrier 1 and the turntable 15 is not supported as shown in FIG.
Even when the pallet 5 is placed on top a, the pallet can be moved up and down and rotated in the same way.

In addition, a plurality of rollers are installed on the supported parts of the front and rear ends of the pallet 5 in order to reduce the resistance when moving between the carrier and the parking room and to cross the gap between the carrier and the parking room. Install.

[0057]

[Effects of the Invention] The mechanical multi-level parking lot of the present invention is as described above, and the horizontal transfer between the pallet carrier and the parking room is carried out between the pallet support part in the carrier and the storage part of the parking room. In between, the upper and lower sides can be moved independently, and since the edges of the pallet are gripped and transferred horizontally, the length of the carrier can be shortened. In this way, the weight of the carrier can be reduced, and the power required to drive the lift up and down can be reduced. In addition, since the upper and lower empty pallets and the pallet on which a car is placed can be replaced at the same time, the operating time can be shortened.

Furthermore, since there is no need to lift the pallet inside the parking room when transferring the pallet between the carrier and the parking room, the height of the parking room can be lowered and the storage efficiency can be increased. By providing the pallet vertical movement means outside the carrier, the structure of the carrier can be simplified.
