DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat conveyor, and more particularly to a slat conveyor used for transferring vehicles in a mechanical parking lot.

[0002]

2. Description of the Related Art As shown in FIG. 9, a mechanical parking lot is provided with a plurality of parking rooms 60 and a traveling vehicle 62 for transporting a vehicle to be transferred to a predetermined parking room. An entrance / exit port 64 is provided on the exit floor, and an elevator 66 for moving the vehicle up and down is provided on each floor.

The parking rooms 60 are provided in parallel in a vertical direction (left-right direction in the drawing), and a traveling path 68 of a traveling vehicle 62 is provided between the rows of the parking rooms 60. The traveling carriage 62 moves in the vertical direction.

[0004] Each parking room 60, traveling carriage 62, entrance and exit 6
4. The elevator 66 is provided with a slat conveyor 10 for transferring a vehicle, as shown in FIG. The slat conveyor 10 is provided separately with a relatively narrow slat conveyor 10a on which the front wheels of the vehicle are mounted and a relatively wide slat conveyor 10b on which the rear wheels of the vehicle are mounted. Then, these slat conveyors 10 transfer the vehicle in the lateral direction (vertical direction in the figure).

[0005] The slat conveyor has a plurality of slat members mounted in a circulating manner via an attachment between parallel endless chains, and a vehicle is transferred by circulating the endless chains.

[0006] A slat conveyor in a mechanical parking lot transfers a vehicle as an object to be conveyed, so that the load received by the slat member is large, and strength, rigidity, and durability (hereinafter, referred to as strength, etc.) are required. . On the other hand, in the slat conveyor, it is necessary to reduce the turning radius of the slat member at its end in order to smoothly transfer the vehicle to the adjacent slat conveyor, and when a person gets on and off the slat conveyor, For safety reasons, it is necessary to reduce the gap between the slat members. Further, as described above, the mechanical parking lot is provided with a slat conveyor for supporting the front wheels of the vehicle and a slat conveyor for supporting the rear wheels in each of the parking rooms, the traveling trolley, the entrance and exit, and the elevator. In order to attach a large number of slat members to the conveyor, it is necessary to facilitate the work of attaching the slat members to the attachment. Further, in a mechanical parking lot, particularly when a slat conveyor is used for a traveling vehicle and an elevator, it is desired to reduce the weight of the traveling vehicle and the elevator in order to reduce the load of the elevator.

[0007] From these needs, the slat member of the slat conveyor used in the mechanical parking lot has been disclosed in Japanese Unexamined Utility Model Publication No.
As disclosed in Japanese Patent Application Laid-Open No. 101471, there is known one having a groove-shaped cross section. As shown in FIG. 11, the slat member is formed by bending both side edges in the longitudinal direction of the support portion 80 downward to form a leg portion 82 and has a groove shape. A ridge-shaped stiffening portion 84 is formed in the portion.

Further, as disclosed in Japanese Utility Model Laid-Open No. 4-111868, a slat member of a slat conveyor used in a mechanical parking lot is known to have a square tubular cross section. As shown in FIG. 12, this square tubular slat member is provided with a support portion 90 for supporting a vehicle so that adjacent slat members do not interfere with each other at the end of the slat conveyor and reduce the gap between the slat members. And a facing portion 92 having a width narrower than the bearing portion 90 and facing the bearing portion, and an inclined leg 94 continuous between the bearing portion 90 and the facing portion 92.

[0009]

However, the slat members of the slat conveyor used in the mechanical parking lot need only have a vertical strength or the like to support the vehicle. Among the above-described conventional techniques, the groove-shaped slat member in which the leg portions 82 are formed on both side edges of the bearing portion disclosed in Japanese Utility Model Laid-Open No. 4-101471 has a cross-sectional shape that is opened downward. Therefore, the workability of attaching to the attachment is good, but the width becomes wider by the plate thickness of the leg portions 82 formed on both side edges of the support portion 80, and the turning radius at the end of the slat conveyor cannot be reduced. It was large and could not be reduced in weight.

Further, the slat member disclosed in Japanese Utility Model Laid-Open No. 4-111868 and having a trapezoidal cross section has a width corresponding to the plate thickness of the inclined leg portion 94.
The result is similar to that of JP-A-101471, and in addition, a large amount of material for forming the slat member is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a slat conveyor which can be reduced in weight without impairing the strength and the like of a slat member.

Another object of the present invention is to provide a slat conveyor capable of reducing the radius of rotation of the slat member at the end of the slat conveyor and reducing the gap between the slat members. is there.

Still another object of the present invention is to provide a slat conveyor in which the slat member can be easily attached to an attachment.

[0014]

In order to achieve the above object, a slat conveyor according to the present invention is provided in which both ends of a slat member are attached to an attachment provided on a link of an endless chain, and a slat for circulating the endless chain. In the conveyor, the slat member includes a support portion for supporting an object to be transported, a single leg, and a reinforcing portion provided at an end of the leg so as to be parallel to the support portion. The width of the portion is narrower than the width of the support portion.

According to another aspect of the present invention, there is provided a slat conveyor according to the present invention, wherein both ends of a slat member are attached to an attachment provided on a link of an endless chain, and the endless chain is circularly driven. The slat member is characterized in that it has a substantially T-shaped cross section from a support portion for supporting a transferred object and a single leg portion.

The slat member may be formed by notching at least an end of a leg thereof or extending an end of a support portion of the slat member to form an attachment portion to the attachment at the support portion. Further, the support portion of the slat member is extended from the lower end portion of the leg portion, and is inclined from the end portion of the support portion to the lower end portion of the leg portion, and the cut portion is formed so that the leg portion does not interfere with the attachment. It may be formed. Further, the ends of the legs of the slat member may be extended to form attachment portions to the attachment.

It is desirable to fix a nut to the attachment. Further, the slat member is desirably attached to the attachment such that the bearing portion has a height substantially equal to the height of the endless chain.

[0018]

With the above construction, the strength of the slat member is increased in the vertical direction by a single leg. Since the single leg is used, the weight of the slat conveyor can be reduced. In addition, the slat member is provided with a reinforcing portion at the end of the leg portion so as to be parallel to the supporting portion, and the width of the reinforcing portion is made smaller than the width of the supporting portion, or the slat member supports the transferred object. And a single leg, so that the slat member at the end of the slat conveyor can have a small radius of rotation and a small gap between the slat members. Can be.

Since the mounting portion is formed on the support portion or the leg portion and the nut is fixed to the mounting portion, the workability of mounting on the attachment is improved.

[0020]
