Description

() HANDLING PLATE-STACKER

The invention relates to equipment for warehouses, namely to lifting platforms of stacker cranes. Known lifting platform of stacker cranes, containing a frame on which are mounted the guides for pallets, located between the guides of the load gripping conveyor, to which the carriages with lifting grips are attached. P.J. . The lifting platform of the stacker crane is known, comprising a frame on which the pallet guides are mounted, a load gripping conveyor interposed between them, mounted on the longitudinal movable beam relative to the frame from the horizontal displacement mechanism, and load gripping elements attached to the conveyor body 2. A disadvantage of the known construction is its complexity due to the use of a crank-and-crank mechanism associated with an electromagnetic clutch with a drive sprocket Yera as a mechanism for horizontal movement of the conveyor beam, and in connection with this the presence of additional control elements of the mechanism. The purpose of the invention is to simplify the design. The goal is achieved by the fact that the mechanism of horizontal movement of the beam contains fasteners fixed on the conveyor body and placed in the initial position on its upper branch above the load-gripping elements located on the lower branch and stops attached to the frame ends and interacting with the said stops.

Fig. 1 shows schematically a warehouse rack installation, serviced by a stacker crane with a load-lifting platform; Fig.2Gruepodnaya platform overall view; in fig. 3 then. same, in the initial position; Figs, k and 5 are the same, at the time of the capture of the pallet to the platform of the piler; Fig. 6 is the same after the end of hauling the pallet to the stacker site,

The lifting platform of the crane stacker contains frame 1, on which a load-carrying conveyor 2 is mounted with load-gripping elements 3 attached to its traction body and. The stars 5 and 6 of the conveyor 2 are attached to the beam 7 mounted on the frame 1 with the possibility of horizontal movement. The conveyor 2 is equipped with an actuator 8, the horizontal displacement mechanism includes stops 9 and 10 fixed on the conveyor body 2, and stops 11 and 12 fixed on the ends of the frame 1. In the initial position the stops and stops are located respectively on the upper and lower branches of the conveyor 2, the distance between elements 3 and 4 is equal to the distance between the grooves 13 and 1 of the pallet 15 o. The load-lifting platform is mounted with the possibility of vertical displacement 1 / (from the actuator 16 in the guides of the 17 stacker screen 18. The crane-stacker is equipped with a horizon drive 19 cial movement. The pallets 15 are installed in the racks 20. On the frame 1 ustanOEsheny guide 21 for pallets 15, for example rollers.

The site works as follows.

In order to unload the pallet 15 from the rack 20, the stacker crane 18 is moved to the corresponding cell. 8, the initial position (FIG. 3) turns on the actuator 8.

The stop 9, reaching the limiter 11, rests against it and moves the beam 7 to the left (Fig. A). At the same time, the element 3 engages the groove 13 of the pallet 15 and pulls it onto the platform (Fig. 5). At the end

loading the pallet onto the platform (FIG. 6), the stop 9, abutted against the stopper 12, returns the beam with the conveyor 2 to the initial position, and the elements 3 and

 fix the pallet on both sides. Drive 8 is turned off. At the same time, the drive 16 of the vertical movement of the platform and the drive 19 of the horizontal movement of the crane are turned on.

Next, the pallet is transported to the place of unloading at the pick, a table (not shown),. .

When loading the rack cycle is similar.

The invention allows to simplify the design of the load-lifting platform, excluding the additional components of the mechanism for the horizontal movement of the load-lifting conveyor and the additional means of control of this mechanism.
