(54) LOADING PLACE FOR THE RANA-STABLE L EPA

i

The invention relates to the equipment of warehouses, in particular, to the lifting platforms of stacker cranes.

The known lifting platform of the crane-stacker, containing the load carrier and the carriage with load grippers fl.

This lifting platform requires wide inter-shelving aisles, thereby reducing the area under the storage area.

The known lifting platform of a 1-piler is a stacker, containing cargo along the direction of movement. for horizontal guides, in which a lifting device with levers is installed, and a drive mechanism for the translational movement of the levers and their rotation in the horizontal plane;

However, the width of the known site must be greater than the width of the pallet, which does not allow for savings of W1O of the shadi warehouse.

The aim of the invention is to save warehouse space by reducing the area of rafters.

This is achieved by the fact that the platform is equipped with toothed racks arranged parallel to the direction of shm and the axes of rotation of the levers are kinematically connected with the toothed ribs.

20 of the electromechanical winch 4 and the system of blocks 5. On the platform 3, horizontal guides 6 are fixed, which are located perpendicular to the movement of the crane and taper. On horizontal lines & FLAXI 6 6 is mounted with the possibility of moving on them a load gripping device, made in the form of a movable carriage 7 with two rotary-movable levers 8 mounted on it with roller 9 at the end of each (see Fig. 3, 4). The carriage 7 is set in motion by means of a spindle, Yu, an electric motor 11 and a gearbox 12 (see Fig. 2). The tilting arms 8 at the edge of the ngos positions of the carriage 7 extend beyond the hectares of barites of the lifting and lowering platform 3 towards the racks and ensure the separation of the pallet 13 with the load. The gear rails 14, kinematically connected through the block shifters 15 and the driven gears 16 with the rotary-movable levers 8 (see. Fig. 4), are integrally formed with the horizontal guides b of the lifting and lowering platform. Thus, the carriage 7 can move along the horizontal guides 6 of the pad 3 with simultaneous movement and rotation of the levers 8 (see the trajectory of the rollers in Fig. 3), and the pallet is extended by rotating the arms when the carriage moves carriage stroke. To release the movable carriage 7 from the pallet in the lower part of the frame 1 of the crane-stacker there are stops 17. The crane-stacker is operated manually from the console 18 mounted on the frame. The console has buttons for stacker forward, stacker back, platform up, platform down, carriage to the left, carriage to the right. Crane stacker works as follows. During the cycle, Take the load by a crane stack with platform 3 is the shortest way to move to the desired cell. In order to hook the pallet 13, the electric motor 11 is turned on, and the carriage 7 with 8 is extended along the lead screw 10 to the extreme position. In FIG. 2 shows the position of the pad 3 at the moment of the capture of the pallet with a load from the right stele of the crap. The rollers 9 of the levers 8 are under the groove of the pallet 13. When the platform 3 moves vertically, the rollers 9 catch the pallet 13. The electric motor 11 is turned on, and the carriage moves along the spindle 10 in the opposite direction, pulling the pallet 13 with the load out of the cell. When this block gear 15, rolling on gear racks 14, rotate the driven gear 16. The levers 8, mounted on the shaft of each of the gears 16, make a complex movement: translational together with the carriage 7 from the driving screw 10 and the rotary around its axis. FIG. 6 shows the position of the pad 3 after removing the pallet with a load from the right stage. At the same time, the rollers 9 make a path along the arc of the ABC and .В., And the pallet with a load, when turning the levers 8 with the rollers 9, makes a linear movement from points A and A in the direction of points B and B. The amount of movement of the pallet during the full carriage stroke is equal to carriage stroke plus two lever lengths (at full carriage stroke, the levers turn on). To remove the pallet with the load from the rack cell and further transport it to the unloading point, the carriage 7 stops in an intermediate position B. B. When the pallet is loaded with a load from the left rack, the same operation is performed. If it is necessary to rearrange the pallet from the rack to the left - see figs. 5 and 6) the platform 3, with the pallet 13 removed from the rack, is lowered to the lower position. In this position, the pallet 13 with the load rests on special stops 17. The carriage 7 with levers 8, located below the pallet, moves under the pallet to the right from position B. B. to position A. A. Rollers 9 levers 8, abutted against the right edge of the pulled out pallet, move the pallet to the left rack by moving the carriage 7 to the left. The reverse cycle of the load is performed in reverse order. Commands for raising and lowering the platform 3, moving the carriage to the right and left are given from the console (1eni, and their accuracy is ensured by the operation of end switches or visually. Such a design of the crane-head unit allows the most efficient use of the storage area due to the minimum width aisles equal to the length of the pallet with cargo plus the necessary clearances, while not limited to the operator 5 any special maneuvering. Crane- "1 stacker with a horizontal area This design is reliable in operation, since in the design of the load gripping device all elements are in rigidly fixed guides. In addition, the drive of the gripping device experiences significantly less dynamic loads, since at the beginning and at the end of the movement (near the extreme positions) the pallet the load has a minimum speed equal to almost the speed of movement of the carriage.In the middle of the way the pallet has a maximum speed, which consists of the speed of movement of the carriage and the angular velocity of rotation of the lever s (converted in this design to the translational movement of the pallet). The load platform allows the loading and unloading of pallets of any d41iN. . JO6 invention due to the reduced dimensions of the site, the levers of the load gripping device are fixed on the carriage, and the drive mechanism contains gear racks arranged parallel to it. both guides and kinematically associated with the axes of rotation of the levers.
