Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention provides a method for connecting a large number of bogie supports movably supported by endless guide rails provided along a horizontal circulation path to endless guide rails stretched along the horizontal circulation path. This invention relates to rotating shelves for carts connected to each other by a shaped drive chain.

0002

[Prior Art] This type of rotary shelf for carts is used to store and manage loaded hand carts for transporting loads, and each cart supporting platform that moves in circulation The truck is equipped with a truck support section that slopes upward to prevent the truck from sliding down by itself.

[0003] In the conventional rotary rack for carts of this type, as described in, for example, Japanese Utility Model Application No. 1-126315, the upper end of the rear vertical wall of the approximately L-shaped cart support A member to which a wheel or roller that engages with the guide rail is pivotally supported and a drive chain is connected is fixedly and protrusively provided at the lower end of the guide rail.

0004

[Problems to be Solved by the Invention] In the conventional configuration as described above, a pair of upper and lower endless guide rails is attached to the frame located inside the horizontal circulation path of the bogie support, and an endless drive chain is stretched. However, if this frame and numerous trolley supports are to be transported separately and then integrated at the installation site, each trolley support must be engaged with the guide rail at the installation site, and the tension has already been removed. Each truck support must be connected to the installed drive chain at equal intervals, which requires a great deal of effort and time to assemble at the installation site. Therefore, in the past, the whole frame had to be assembled at a factory and then transported to the installation site, and it was very costly to transport and install a large shelf with trolley supports that protruded from both the front and rear sides of the frame and from both ends in the length direction. There was a drawback that it took a while.

[0005]Furthermore, when the cart support stand configured in a substantially right-angled L shape is supported by the guide rail, the cart support part of the cart support stand engages with the guide rail so as to be tilted upward at a predetermined angle. When the members on which the wheels and rollers are pivotally supported and to which the drive chain is coupled are fixedly protruding from the upper and lower ends of the rear vertical wall of the truck support, these members and the rear vertical wall of the truck support It is necessary to weld the two parts with a predetermined angle between them, which also has the disadvantage that it takes a lot of effort to assemble the trolley support.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention provides a rotary shelf for a cart as described above, in which the cart support base is connected to the endless guide rail. a substantially vertical moving frame supported by and connected to the endless drive chain; a vertical wall section detachably attached to the front side of the moving frame; and a trolley support extending forward at right angles from the lower end of the vertical wall section. and a substantially L-shaped support body consisting of a support base body, the support base body attachment seat provided at the lower front side of the movable frame protruding forward beyond the support base body attachment seat provided at the front upper part of the movable frame. The present invention proposes a rotary shelf for a trolley, which is configured such that the trolley support section is inclined upward and forward when the vertical wall section of the support main body is attached.
