Description

one

The invention relates to warehousing equipment, in particular to devices for loading and unloading racks.

A device for loading and unloading racks is known, which includes stacker cranes with a lifting platform l.

The disadvantage of this device is low productivity due to long runs of stacker cranes.

It is also known a device for loading and unloading racks, containing feed and discharge conveyors, stackers cranes having a vertical frame on which a lifting platform with a load feeding mechanism in the racks and a load from the racks 2 are movably mounted.

The disadvantage of this device is the complexity of the design due to the fact that it is equipped with additional overload mechanisms.

The purpose of the invention is to simplify the design.

This is achieved by the fact that the lifting platform is made in

the form of the rotary section of the roller table, installed with the possibility of combining its longitudinal axis with the longitudinal axis of the conveyors, and the conveyors contain separate kinematically interconnected sections mounted with the possibility of vertical movement, while the frame of each stacker crane is equipped with

0 stops interacting with the mentioned sections of the conveyors.

A device for loading and unloading racks includes conveyors 1 for loading and unloading cargo mounted along racks 2 parallel to the front of the cell racks

0 (Fig. 1) or the end of the aisle racks (Fig. 3), the stackers 3 installed on rails 4, laid on the floor along the shelves 2 and conveyors 1. The stacker 3 includes a vertical frame 5, in the guides which is mounted with the possibility of vertical movement of the lifting platform 7, made in the form of a rotary section of the drive roller 8. In the lower position, the platform 7 is coaxially adjacent to the conveyor 1, and the rollers 9 of the roller table 8 are in the same plane with the carrying rollers 10 of the conveyor 1. The conveyor 1 is made in the form of sections 11, each of which (fig.b) is formed 12 with rollers 10 supported through hinge racks 13 on the base 14 of the conveyor 1. Section 11 is equipped with a spring 15 fixed on the base 14 and the rack 13 and two shoulders lever 16 interacting with the stop 17 mounted on the frame crane stacker 3. The rollers 10 of all sections 11 (FIG. 3) are driven by a reversing drive 18 through chain drives 19. The end of the load-lifting platform 7 adjacent to the racks 2 (Fig.7 and 8) is equipped with a mechanism for feeding and selecting load from the platform to the rack and vice versa, including roller 20, mounted on a folding articulated arm 21 connected to a pneumatic cylinder stem 22. The roller 20 is connected to the roller 9 of the roller table via a chain 23

8 lifting platform 7 and interacts with the load 24 when it is fed or selected from the rack 2.

The device operates as follows: load 24 loaded into a stella 5k 2 along a conveyor 1 podioot on a rotary driving roller table 8 of a lifting platform 7. After that the lifting platform 7 rises to the selected floor of the rack 2, the plane of the rollers 9 of the roller table 8 is aligned with the carrier plane of the floor the rack driving roller 20 through a lever 21, the pneumatic cylinder 22 is inserted into the rack 2, and the load is fed to the rack section. Then the roller 20 is led out of the rack (in Fig. 8 is shown by an arrow), the lifting platform 7 is lowered to its lowest position, the next weight is fed to it through the conveyor 1, and the cycle is repeated.

When unloading the racks, the load-lifting platform 7 of the stacker crane 3 rises to the selected floor of the rack, bearing the plane of the rollers

9 is aligned with the floor plane,

A drive roller 20 is inserted into the rack cell, which, interacting with the load base 24, leads it from the rack to the rotary drive roller table 8 of platform 7, after which the platform is lowered down, carrying the plane of roller 9 of the roller table 8

combined with the carrier plane of the rollers 10 of the conveyor 1, and the load 24 is transferred to the conveyor 1 and further to the place of collection. The peripheral speed of the rotary section rollers 9 is chosen such that the movement time of the load 24 on the roller table 8 is considerably longer than the lifting time of the load-lifting platform 7 to the outermost position of the rack 2. Due to this, the load moves continuously in the process of loading and unloading the racks without jerks, which is important when storing unstable and prone to scattering cargo placed on the pallet. The free movement of the lifting platform 1 and 7 along the conveyor 1 and the constant communication between them during operation of the device is ensured by the vertical movement of the section 11 of the conveyor 1, which is carried out by acting on the stop 17 of the frame 5 on one of the arms of the two shoulders 16.

The proposed device for loading and unloading racks is characterized by simplicity of construction, smaller in size compared with the known device. The use of the invention will reduce the storage area by 35-40%, and the utilization rate of the storage volume to be increased to 0.6. In addition, reliable storage of goods disposed to scattering or fragile products stacked on pallets is ensured.
