Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a circulating mobile parking device.

(Prior Art) In general, a circulation type mobile parking device has a structure in which a circulation path for circulating a plurality of pallets carrying vehicles and a vehicle loading/unloading section above the circulation path are connected by a lift for raising and lowering the pallets. . For example, in the horizontal circulation movement type, there are two parallel horizontal transfer paths that transport pallets in the horizontal direction, and one end of each horizontal transfer path intersects with the other end of the two horizontal transfer paths. A circulation path for horizontally circulating the pallets is constituted by two vertical transfer paths for vertically transferring the pallets. In addition, in the box-type circulating movement type, there are two horizontal transfer paths that are vertically spaced apart to transfer pallets laterally, and one end of each of these horizontal transfer paths intersects with the other end. A circulation path for vertically circulating the pallets is constituted by two vertical transfer paths for vertically transferring the pallets between the two horizontal transfer paths.

In such a circulating parking system, a turntable is provided in the vehicle loading/unloading section, and a pallet supported by a lift is fitted into a pallet fitting opening provided at the center of the turntable. It is common practice to rotate the device by means of a turntable (see, for example, Japanese Patent Publication No. 63-5539).

Therefore, when entering the warehouse, the driver advances the vehicle from the entrance of the building onto an empty pallet that has been placed in the entrance/exit area using a lift, and when exiting the warehouse, the vehicle is placed in the same position as when entering the building (with the rear of the vehicle facing the entrance/exit). Even if the driver lifts the vehicle into the entry/exit section with the lift, by changing the orientation of the vehicle 180 degrees using the turning means, the driver can take the vehicle out of the entrance while moving the vehicle forward.

Of course, it is also possible to change the direction of the vehicle using the turning means when entering the warehouse and move it to the circulation transfer path using a lift, so that the direction of the vehicle does not change when leaving the warehouse.

In addition, in the above-mentioned horizontal circulation movement type, a lift is provided outside the circulation path to raise and lower the pallets between the loading/unloading section and the circulation path, and this horizontal circulation path is further arranged in multiple layers above and below. However, since it does not have a means to transfer pallets between each layer like the box type 1 circulation type, there is no means for moving pallets between the above-mentioned loading/unloading section and each circulation path. Usually, a lift is installed (for example,
(See Publication No. 3).

On the other hand, in the case of a box-type circulating type, the vertical transfer path at one end is usually extended to the loading/unloading section, and is used for raising and lowering pallets between the loading/unloading section and each layer.

(Problem to be solved by the invention) Incidentally, the above-mentioned vehicle entry/exit area is often provided on the first floor of a building facing the road, but generally the area adjacent to the above entry/exit area on the first floor is a store. It is usually used for highly profitable purposes such as However, in the above-mentioned conventional technology, if an entry/exit section is provided on the first floor,
A large space must be secured there for vehicles to turn around, and even if this first floor is to be used for profitable purposes, there is a problem in that the usable space becomes narrow. Furthermore, the method of turning the vehicle by inserting a pallet into a turntable requires a large turntable, and such turning means increases the manufacturing cost of the parking equipment.

Furthermore, in the case of the horizontal circulation type, since the lift is located outside the circulation path, there is a problem that the space available for parking is narrowed due to the lift, which means that the number of parking spaces is reduced.

Furthermore, in the case of a box-type circulating type, a lift is installed at one end, so in order to transport a pallet located far away from the lift to the lift, it is necessary to repeatedly move the pallet horizontally and vertically. There is a problem that the more pallets are placed on the horizontal transfer path, the longer it takes for vehicles to enter and exit the warehouse.

In other words, the first object of the present invention is to enable pallets to be rotated in a horizontally circulating mobile type without providing a dedicated space in the parking section or loading/unloading section, and to save space within the building. The goal is to increase usage efficiency.

3. The second problem is to increase the efficiency of space utilization within the building while smoothing the lifting and lowering of pallets between each layer and the loading/unloading section when multiple layers of horizontal circulation paths are provided.

Furthermore, the third problem is to shorten the loading and unloading time in the box type circulating type.

(Means for Solving the Problems) To solve the first problem, a lift equipped with a turning means is arranged at an intermediate position in the longitudinal direction of the lateral transfer path.

In that case, the engaging/disengaging means may be constructed of a vertical movement means for vertically moving the pallet to be raised and lowered by a lift (fourth means).

Moreover, the above-mentioned vertical movement means can be constituted by a jack provided on the lateral transfer path (fifth means).

Moreover, the above-mentioned vertical movement means can also be used as a lift (sixth means).

The third problem is addressed by providing the lift at an intermediate position in the longitudinal direction of the lateral transfer path.

That is, the specific means for this purpose is to have a plurality of lateral transfer paths provided vertically at intervals for laterally transferring pallets on which vehicles are placed, and one end and the other end of each lateral transfer path. The parking device is a box-shaped circulation type parking device, which has a circulation path that vertically circulates the pallets, and is composed of two lower transfer paths that intersect with each other and transfer the pallets vertically between the horizontal transfer paths. 0 A pair of horizontal transfer rails provided in each horizontal transfer path and extending in parallel to guide the horizontal transfer of pallets, and a pair of horizontal transfer rails provided in each of the above pallets that engage and connect horizontally adjacent pallets with each other in the horizontal transfer. and a central position determined with a space of at least one pallet between each lateral transfer path corresponding to the upper and lower sides of each circulation path and the upper and lower transfer paths at both ends, and a position above or above the center position. A lift having a lifting platform for raising and lowering pallets between a vehicle loading/unloading section provided below, and a release of the engagement between the pallet located on the lifting path of the lifting platform and the pallets on both sides thereof by the connecting means. The lateral transfer path in which the pallet is lifted and lowered by the above-mentioned lift I. A lateral transfer means for laterally transferring one of the released pallets on both sides toward one of the upper and lower transfer paths so as to leave the lift, and the other pallet of the pallets on both sides. and a lateral transfer means for laterally transferring the pallet on the hoisting path that is engaged with the other pallet by the engaging and disengaging means toward the other vertical transfer path so as to leave the lift; A movable rail formed separately from the horizontal transfer rail is provided at the position where the platform passes, and this movable rail is connected to the horizontal transfer rails before and after it to guide the horizontal transfer of the pallet at the passing position. The recirculating mobile parking device is movable between a support position where the pallet is supported and a retracted position where the platform is separated from the front and rear lateral transfer rails and allows the platform to pass. (Seventh means).

In the means for solving the third problem, the connecting means is

(Eighth means).

Further, the above-mentioned "two-part moving means" can be constituted by a jack provided on the lateral transfer path (ninth means).

Furthermore, the vertical movement means can also be used as a lift (tenth means).

(Function) In the means for solving the first problem (first means), since the lift is provided on the circulation path, there is a lateral protrusion from the circulation path, that is, a lift for lifting and lowering the pallet. The protrusion is eliminated, and the circulation path is formed larger in the limited space by 3.
Increasing the number of vehicles parked in China will become an iiJ function. In this case, the engagement between the pallet to be lifted and lowered and the pallets on both sides thereof by the connecting means can be released by the engaging and disengaging means, so that the pallet can be moved up and down smoothly.

Furthermore, the direction of the vehicle can be changed by turning the pallet on the circulation path, so there is no need to ensure a large turning space in the loading/unloading section. And of the above circulation route.
When turning the pallet in step 2, the pallets on both sides become an obstacle, but in order to deal with this, the engagement of the pallet to be turned and the pallets on both sides by the connecting means is released by the engagement means, and the pallet is rotated. The pallets on both sides are laterally transferred toward the vertical transfer paths at both ends so as to be separated from each other. As a result, empty spaces can be formed on both sides of the pallet to be rotated, and the pallet can be rotated without interference with others.

In this case, if the pallet is rotated at the end of the horizontal transfer path, that is, at the intersection of the horizontal transfer path and the vertical transfer path, there will be an extra turning space to the side of this intersection to allow the pallet to turn. However, in the case of the present invention, the turning position of the pallet is in the middle of the horizontal transfer path, so there is no need to secure the above-mentioned extra space.

In the means for solving the second problem (second means),
Since the lift is arranged in the circulation path, it becomes possible to form a large circulation path in a limited space and increase the number of parking cars, similar to the means for solving the first problem. Then, by releasing the connection between the pallets using the engagement/detachment means, creating an empty space using the lateral transfer means, and moving the movable rail to the retracted position, a space is created at the position where the elevating platform passes vertically. , the pallet can be moved up and down smoothly using a lift without interference with other objects.

In the third means, since the connecting means is constituted by the L-shaped first coupler and the inverted-shaped second coupler, the engaging surfaces of both the couplers are brought into contact with each other. Adjacent pallets can be connected by engaging each other during lateral transfer, and since each coupler is open in both vertical directions, separation due to relative vertical movement of pallets can be avoided. is acceptable. In this connecting means, since the engaging and disengaging means is a vertical moving means, the pallets to be raised and lowered can be moved in the vertical direction by the lift and the pallets can be disengaged from each other.

In the fourth means, the first coupler is provided with an engaging part that projects in one direction in the vertical direction from the L-shaped base, and the second
Since the coupler is provided with an engaging part that protrudes from the inverted-shaped base to the other side in the vertical direction, the engaging surfaces of the engaging parts of both the couplers come into contact with each other, that is, they engage, so that they are mutually connected. Adjacent pallets can be connected to each other by lateral transfer, and since the upper and lower engaging parts of both connectors are open, separation due to relative vertical movement of the pallets is allowed. It is. In this connecting means, since the engaging and disengaging means is a vertically moving means, the pallets to be raised and lowered can be raised by the lift 6 to release the pallets from each other.

In the fifth means, since the vertical movement means is constituted by a jack, the pallet can be moved up and down relatively easily.

In the sixth means, since the vertical movement means is also used as a lift, there is no need for a special vertical movement means.

In the means for solving the third problem (seventh means),
Since the lift is provided in the middle of the lateral transfer path, the distance between the lift and the pallet placed in the lateral transfer path of each layer is shortened. Therefore, the number of repetitions of horizontal transfer and vertical transfer to send the pallet to the lift is reduced, and the lift j.
It is possible to improve the operating efficiency of the vehicle and reduce the time required for vehicles to enter and exit the warehouse.

In the eighth means, the connecting means includes a first connector having an engaging part that projects in one direction in the vertical direction from the tip of the base that projects in the horizontal direction, and a first connector that projects in the horizontal direction from the tip of the base in the vertical direction. and a second coupler having an engaging part protruding from the other side of the pallets, the engaging surfaces of the engaging parts of both couplers are brought into contact with each other to connect horizontally adjacent pallets. In addition, it is possible to allow the pallets to move apart and enter the engaged state due to relative vertical movement of the pallets. In the connecting means, the engaging and disengaging means is constituted by a vertically moving means;
The pallets that should be raised and lowered by the lift can be raised and the pallets can be disengaged from each other.

The operations of the ninth means and tenth means are substantially the same as those of the fifth means and sixth means described above.

(Effect of the invention) According to the means for solving the first problem (first means), in the horizontal circulation mobile parking device, the lift is provided at an intermediate position of the horizontal transfer path, and the lift is provided with a turning means. In order to release the connection between the pallets using the connecting means and move the 8 pallets on both sides of the lift in the direction of separation, it is necessary to provide a space dedicated to raising and lowering the pallets in the parking area where the circulation path is located. As a result, the number of parking spaces can be increased. Furthermore, since the lift can be placed anywhere in the t-open position of the lateral transfer path, the degree of freedom in selecting the placement location of the loading/unloading section is increased. In addition, since it is possible to change the direction of the vehicle and exit the garage without interfering with others on the circulation path, there is no need to provide space for the vehicle to change direction in the entrance/exit section, reducing the space occupied by the entrance/exit section. The space around the parking device can be used effectively, and a large turntable is not required, so the manufacturing cost of the parking device can be reduced accordingly.

According to the means for solving the second problem (second means), since a lift is arranged in the circulation path, it is possible to increase the number of parking cars as well as the arrangement of the loading/unloading section. The degree of freedom in selecting the location is increased, and since the connecting means for releasing the connection between the pallets by the connecting means, the horizontal transfer means, and the movable rail are provided, the lifting platform can be raised and lowered without interference with others.
