First, the first embodiment will be described. In this embodiment, a vehicle carrier 2 is formed with a vehicle storage compartment 2 composed of three-stage vehicle storage decks 31, 32, 33. The elevator shaft is vertically penetrated through the left end portions of the respective storage decks 31 to 33. 30 is formed, and the lifter 1 is vertically movable in the elevator shaft 30. Since the storage deck 31 is provided with a boarding / alighting berth 5 for vehicles as will be described later, this may be particularly referred to as a boarding / alighting / storage deck.

A conveyor 3 is attached to each of the storage decks 31 to 33, and a conveyor 1a is also attached to the floor surface of the lifter 1 so that a vehicle (automobile) 10 can be moved by the conveyors 3 and 1a. ing. The access decks 7, 7 are formed on both left and right sides of the storage deck 31, and the ramps 4, 4 are connected to each of the entry ports 7, 7, and each of the entry ports 7, 7 is further connected.
A conveyor 5a is provided on the boarding and unloading berths 5, 5 adjacent to. The conveyor 5a moves the vehicle 10 that has traveled to the boarding / alighting berth 5, 5 onto the conveyor 1a of the lifter 1 (see FIG. 1,
In FIG. 2, it has a function to move to the left) or to move onto the conveyor 3 on the storage deck 31 (to the right in FIGS. 1 and 2).

Here, if the vehicle storage compartment 2 is constructed as a total frame structure by the pillars 8, the vertical bones 11 and the horizontal bones 12 as shown in FIG. 3, it is not necessary to provide a deck in the vehicle storage compartment. The vertical bones 11, the horizontal bones 12, and the pillars 8 support the lifter 1 and the conveyor 3, and also have a function as an aggregate that maintains the structural strength of the hull. With the above-described configuration, when the vehicle 10 is loaded, the vehicle 10 is self-propelled to the loading / unloading berth 5 of the loading / unloading / storage deck 31 through the ramp 4 through the ramp 4. At the boarding / alighting berth 5, the driver gets out of the vehicle 10 and goes out of the ship through the passage 6.

On the other hand, when it is confirmed that the driver gets out of the vehicle, the conveyor 5a provided on the floor of the boarding berth 5
Is activated and the vehicle is moved to the lifter 1. When the vehicle is loaded onto the lifter 1, the lifter 1 will
Elevate to 32 or 33 and stop. After stopping, the vehicle is moved to the storage compartment 2 by the conveyor 1a and the conveyor 3. When the vehicle is moved to the vehicle storage compartment 2, the lifter 1 returns to the same level as the loading / unloading and storage deck 31 for the next storage operation. When unloading the vehicle, the procedure is the reverse of loading. That is, the vehicle 10 stored in the vehicle storage section 2 is moved to the lifter 1 by the conveyor 3,
Next, the lifter 1 is moved up and down on the deck 31 for loading and unloading. After the lifter 1 stops at the loading / unloading and storage deck 31, the vehicle 10 is moved to the boarding / berthing berth 5 by the conveyor 1a and the conveyor 3 and the driver gets in the vehicle at the boarding / alighting berth 5 and self-propels through the boarding gate 7. It is carried out of the ship through the lamp 4.

When the vehicle is stored in the storage deck 31, the vehicle is moved directly from the boarding / alighting berth 5 to the conveyor 3 on the storage deck 31. Further, when the vehicle is stowed and unloaded, on the stowage decks 31 to 33, the conveyor 3 has the vehicle (1
The vehicle is moved by a distance corresponding to the vehicle width dimension (accurately, slightly larger than the vehicle width) of the vehicle, and the vehicle is stored while being mounted on the conveyor 3. That is, the conveyor 3 has a role of moving the vehicle and is also a storage place of the vehicle. Further, it goes without saying that the vehicle is fixed by the usual fixing means when the vehicle is stored.

Next, an example in which the above-mentioned storage work and loading / unloading work are automated will be described. FIG. 4 shows a system diagram of the automatic storage system, and reference numeral 20 denotes a host computer. The host computer 20 is mounted on each of the computers 23, 23, ... And each lifter for detecting the storage state of each storage deck 31-33 by receiving the signal of the storage detection sensor 24 installed on each storage deck 31-33. A sensor 25 for transmitting a signal indicating that the vehicle has been loaded onto the lifter is connected, and is operated by a signal from the host computer 20 to control the conveyors 1a, 3 and 5a and a controller 21 for the lifter 21. Are connected. The vehicle 10 is loaded into the boarding berth 5 and the driver dismounts and the "START button"
When is pressed, the conveyor 5a on the floor of the boarding / alighting berth 5 is activated, and the vehicle is carried into the lifter 1.

The sensor 25 of each lifter 1 sends a signal to the host computer 20 that the vehicle 10 has been loaded into the lifter 1. Since a storage schedule indicating how many storage decks can be stored in the host computer 20 is input in advance, a signal is sent to the lifter control device 21 according to the schedule, and the lifter 1 moves to the corresponding storage deck. When the lifter 1 reaches the relevant storage deck, the sensor 24 on the storage deck operates and the conveyor control device is activated.
A signal is sent that the vehicle has arrived at 22. After receiving the signal, the conveyor control device 22 is activated, and the conveyor 1a on the floor of the lifter 1 and the conveyor 3 on the storage deck are activated to move the vehicle to the storage deck. A sensor 24 is attached to the entrance of each storage deck, and when the storage is detected, a signal is sent to the computer 23 on each storage deck. The storage condition of the storage deck is recognized by the computer 23, and the information is sent to the host computer 20. In this way, when the automatic storage system as shown in FIG. 4 is added, the storage and loading / unloading of the vehicle can be automated.

As described above, the vehicle storage device of the vehicle carrier of the first embodiment has the following effects. (1) The manpower required for storage is reduced, the storage time is shortened, and the cargo handling efficiency is improved. (2) It is safe because the driver does not go to the storage place. (3) The number of deck vehicles in each storage deck is managed by a computer, so it is easy and accurate. (4) When the vehicle storage compartment has the total frame structure shown in FIG. 3, it is not necessary to provide a deck in the vehicle storage compartment, the weight of the vessel can be reduced, and various performances of the vessel can be improved. (5) The working environment on board is improved because there are no more vehicles to run on board.

Next, a second embodiment will be described. The second embodiment differs from the first embodiment described above in that, in the second embodiment, a vehicle 10 that has traveled on its own from a boarding gate 7 via a ramp 4 gets on and off. This is the point where the storage pallet 13 prepared in the berth 5 is transported to the vehicle storage compartment 2. Therefore, in the case of the second embodiment, as shown in FIGS. 5 and 6, when the vehicle 10 is loaded, the vehicle 10 passes through the ramp 4 and enters the boat through the loading port 7 and is prepared for the boarding / alighting berth 5. It will run to the top of the storage pallet 13 in which it is stored. At this point in time, the driver dismounts from the vehicle and lashes the vehicle onto the storage pallet 13, which differs from the case of the first embodiment. The procedure thereafter is the same as that of the first embodiment.

In addition to the case of the first embodiment, the vehicle 10 that has been carried by the storage pallet 13 to the loading / unloading berth 5 at the loading / unloading berth 5 requires the work of releasing the fastening at the loading / unloading berth 5. It doesn't differ. When the vehicle is stored, the vehicle 10 is stored on the conveyor 3 while being mounted on the storage pallet 13. Further, when the vehicle is stowed and unloaded, the conveyor 3 is moved by a distance corresponding to the lateral width dimension of the stowage pallet 13 (more accurately, a slightly larger dimension).

Next, a procedure for storing the empty storage pallet 13 will be described. As shown in FIG. 8, a storage space 34 for the storage pallet 13 is formed on the upper part of the loading / unloading and storage deck 31. And on the floor of this storage space 34 is a conveyor
15 are provided. On the other hand, as shown in FIGS.
A pallet raising / lowering arm 14 capable of holding the storage pallet 13 from below is provided at the left end of the loading / unloading deck 31 for the lifter 1.
Is disposed adjacent to the elevator shaft 30 of FIG. A pallet moving conveyor 3a is attached to the loading portion of the storage pallet 13 above the arm 14. When the vehicle is loaded, the pallet lifting / lowering arm 14 extends to the storage space 34 (indicated by the dotted line in FIG. 8), and the storage pallet 13 located at the top is placed on the arm 14 by the operation of the conveyor 15.

Then, when the arm 14 descends to the loading / unloading and storage deck 31, the storage pallet placed on the arm 14 is stored.
13 transfers onto the conveyor 3 on the loading / unloading and storage deck 31.
On the other hand, a vehicle that has been self-propelled to the storage pallet in this state gets on and the vehicle is mounted on the storage pallet 13. After that, the storage pallet 13 is moved according to the procedure described above. When loading and unloading the vehicle, the arm 14 is at the position of the loading and unloading berth 5. When the storage pallet 13 equipped with a vehicle moves to the boarding / alighting berth 5 and the vehicle runs away by itself, the arm 14 empties the storage pallet 13 and rises to the height of the pallet storage space 34. When the arm 14 reaches this position, the conveyor 3a on the arm 14 operates to send the storage pallet 13 to the storage space 34. When the system for automating the handling of the storage pallet 13 described above is incorporated into the automatic storage system of FIG. 4 described above, the automation of the entire process becomes possible. According to the second embodiment, in addition to the effects of the first embodiment described above, since the vehicle lashing work can be performed at the boarding / alighting berth, it is necessary for an operator to go out to the storage place and tie up the vehicle as in the conventional case. It is possible to reduce the number of workers and to increase the safety.

Further, a third embodiment will be described. The difference of this embodiment from that of the above-mentioned first embodiment is that in the third embodiment, as shown in FIGS. 10 and 11, a turntable 16 is attached to the boarding / alighting berth 5. It is a point. Therefore, in the case of this embodiment, when the vehicle 10 is loaded, the vehicle 10 travels through the ramp 4 to the turntable 16 through the entrance 7. At this point, the driver exits the vehicle and exits the ship through passage 6. After it is confirmed that the driver gets out of the vehicle, the turntable 16 rotates 90 degrees, and the conveyor 16a provided on the floor of the turntable 16
The conveyor 3 in the vehicle storage compartment 2 and the conveyor 1a in the lifter 1 are aligned with each other, and the vehicle is moved to the lifter 1 by the conveyor 16. When the vehicle 10 is loaded into the lifter 1, the lifter 1 is moved to a predetermined storage deck 32 or
Elevate to 33 and stop. After the stop, vehicle 10 is lifter 1
Is conveyed to the vehicle storage compartment 2 by the floor conveyor 1a and each storage deck conveyor 3. Note that the vehicle 10 is stored in the same direction as the moving direction of the conveyor 3 unlike the above-described embodiments.

When the vehicle is moved to the vehicle storage compartment 2, the lifter 1 returns to the loading / unloading and storage deck 31 for the next storage operation. The procedure for loading the vehicle is the reverse of loading.
That is, the vehicle 10 stored in the vehicle storage compartment 2 is
It is conveyed to the lifter 1 by the conveyor 3. After the vehicle 10 is loaded into the lifter 1, the lifter 1 is used for loading / unloading and storage deck.
Go up and down to 31 and stop. After the lifter 1 is stopped, the vehicle 10 is carried into the turntable 16 by the conveyor 1a.
After loading the vehicle, the turntable 16 rotates 90 degrees, and the vehicle 10 faces the entrance 7. At this time, the driver gets into the vehicle and is carried out of the ship through the ramp 7 from the entrance 7 by self-propelling. Needless to say, also in this embodiment, the storage operation can be completely automated by automatically performing the above-described operations by the computer. According to this embodiment, in addition to the above-mentioned effects in the first and second cases, since the direction of the vehicle can be freely changed by using the turntable, only the forward operation of the vehicle is required for the movement work of the vehicle manually, The effect is that it leads to improvement in efficiency.

Next, a fourth embodiment of the present invention will be described. The difference of this embodiment from the above-mentioned first to third embodiments is that the berth member for getting on and off is configured to be movable, and the driver is unloading when the vehicle is unloading. The point is that the vehicle does not have to enter the ship and can be loaded and unloaded from the mobile berth that has protruded above the quay. That is, in FIGS. 12 to 14, reference numeral 40 indicates a movable boarding / alighting berth that can be horizontally extended in the vessel-side direction.
