Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvements in elevator parking devices, and particularly to measures for positioning a swivel platform on which pallets are placed.

(Prior Art) Conventionally, as an elevator type parking device, as disclosed in, for example, Japanese Patent Application Laid-open No. 62-268475, a plurality of parking shelves for storing vehicles together with vehicle loading pallets are installed inside a parking tower. are arranged in layers in the vertical direction, and in a pit below the hoistway extending in the vertical direction formed on the side thereof, a turning device is installed that turns the vehicle at a predetermined angle in a horizontal plane together with the pallet in preparation for loading and unloading the vehicle. What is known is what is known. In this turning device, when a pallet is turned in preparation for loading and unloading a vehicle at 0, the pallet is transferred from the lifting table to the turning table of the turning device by lowering the lifting table, and then the lifting table is further lowered. Is the above-mentioned swivel table designed to rotate in the retracted state?
Boat fishing. In this case, by locating the upper surface of the vehicle entry portion of the pallet on the swivel base and the upper surface of the boarding deck on substantially the same plane, vehicles can be smoothly transferred between the two when entering and exiting the warehouse.

However, in the above-mentioned swivel device, the swivel base only rotates in a horizontal plane in preparation for loading and unloading, so if the top surface of the vehicle entrance portion of the pallet and the top surface of the loading deck are positioned on approximately the same plane as described above, Since the side part of the pallet is generally set higher than the vehicle entry area, there is a problem in that the difference in level between the upper surface of the pallet side part and the upper surface of the boarding deck becomes large, making it difficult to get on and off the vehicle.

Therefore, recently, a swivel device that has an elevating function added to the above-mentioned swivel function, that is, a swivel table on which a pallet is placed, an elevating support table that supports the swivel table and raises and lowers it, and a swivel device that raises and lowers the swivel table horizontally on the lifting support table. A swivel device has been developed that includes a swivel actuating means for swiveling the device, and a lifting device for raising and lowering the lifting support. In addition, in the type with this lifting function, the lifting and lowering movement of the swivel table avoids interference with the lifting table, and the top surface of the side of the swivel table/paddle and the top surface of the boarding deck are approximately on the same plane. can be positioned above.

(Problem to be Solved by the Invention) By the way, in an elevator type parking device equipped with a turning device configured as described above, there is a cross-feeding device that cross-feeds Nocle/Soto between a lifting platform and a parking shelf when entering and exiting a garage. In some cases, a traveling rail on which the wheels of the barre-soto are mounted and which allows the pallet to travel in the direction of transport is provided on the lifting platform side. In this case, to explain taking out of a vehicle as an example, first, a pallet is transferred from a predetermined parking shelf onto a lifting platform via the above-mentioned cross-feeding device and traveling rail. At this time, the wheels of the pallet engage with the running rails, and the engagement bins on the cross-feeding device engage with the engagement grooves of the guide plate of the nodelet, positioning the pallet in the front-back and left-right directions. . Next, the pallet is placed on the turning table of the turning device by the lowering operation of the lifting table. Thereafter, this pallet gutter is lifted by the lifting operation of the swivel table, and the engagement with the traversing device and the traveling rail is released.

Thereafter, the pallet is rotated by a predetermined angle by the rotation operation of the swivel table, and then engaged with the traversing device and the running rail again.

However, for example, if the swivel base is slightly inclined with respect to the horizontal plane, the load on the swivel device fluctuates depending on the weight and position of the vehicle mounted on the pallet, or the swivel stop position of the swivel base changes due to play in the swivel device. If such fluctuation occurs, a situation may occur where the engagement between the wheels and the running rail and the engagement between the engagement pin and the engagement groove of the guide plate are not performed properly as described above, and in this case, the vehicle You will no longer be able to issue the item.

The same thing can be said when warehousing.

The present invention has been made in view of the above, and its purpose is to regulate the rotation of the swivel base by utilizing the descending movement of the swivel base in preparation for loading and unloading the swivel base, so that the swivel base can be operated normally. The objective is to ensure that the vehicle is positioned at the turning position.

It is arranged to engage with the positioning member.

(Function) With the above configuration, in the present invention, for example, when leaving a warehouse, a pallet on which a vehicle is mounted is transferred from a predetermined parking shelf to a pallet on a lifting platform via a cross-feeding device and a running rail, and After the table is placed on the turning table of the turning means by the subsequent lowering movement of the table, it is lifted by the raising movement of the turning table.

As a result, the engagement between each wheel of the pallet and the running rail and the engagement between the engagement pin on the side of the traversing device and the engagement groove on the guide plate of the pallet are temporarily released, and the pallet is moved at a predetermined angle in the horizontal plane. be turned around.

Thereafter, due to the downward movement of the swivel table, each wheel of the pallet is engaged with the traveling rail again, and the engagement pin on the side of the traversing device is engaged with the engagement groove of the guide plate of the pallet, and the pallet is Positioning is performed in the front-back and left-right directions. At the same time, the positioning pin on the rotating base side or the positioning member on the stationary side is engaged.

For this reason, for example, if the swivel table is slightly inclined with respect to the horizontal plane, if the load on the swivel device fluctuates depending on the type plate and position of the vehicle mounted on the pallet, or if the swivel device is loose, the swivel table will not rotate properly. Even if the stop position fluctuates, the position is corrected by the engagement between the positioning pin and the positioning member, and the swivel base is reliably positioned at the normal swivel position.
