Description

one

The invention relates to storage equipment for industrial warehousing and relates to devices for loading and unloading shelves of warehouses.

The known devices for loading and unloading shelves of a warehouse, containing a horizontally movable frame with vertical guides and a lifting load gripper in the form of a comb located along the shelves, have high productivity and have a number of other obvious advantages.

one.

However, in such devices either there is no possibility of servicing the racks located on either side of the device, or the space necessary for moving the supporting beam of the railing disappears between the shelves of the racks. Loss in height reduces storage capacity and results in poor utilization of storage space.

A device is known for loading and unloading racks, comprising a frame that is movable in a horizontal plane and has vertical guides, in which a horizontal beam in a vertical plane is movably mounted and a beam with console support arms 2 mounted on it.

A disadvantage of the known device is the impossibility of selectively stacking loads on racks or selectively removing loads from racks.

The aim of the invention is the expansion of technological capabilities by providing selective stacking of goods on the racks and selective removal of goods from the racks.

This is achieved in that the load-carrying strips are fixed on the beam by means of hinges with the possibility of rotation in the vertical plane relative to the beam on which the fixings are mounted for interacting with the said load-carrying strips. At the same time, at least one plank has a socket for interaction with a clamp, and the hinges for fastening the planks are located in the places of installation parallel to the beam, and the angle of rotation of the planks is 90 °.

FIG. 1 shows a general view of the described device; in fig. 2 - view A of FIG. one; in fig. 3 is a section BB of FIG. one; in fig. 4 shows a section bb of FIG. one.

The device includes a frame 1 with vertical guides 2 mounted on the frame, moving in a horizontal direction relative to shelves 3 for storing loads and placed with aisles between adjacent shelves to enable them to be serviced by the said device.

In vertical guides, a lifting cargo grip 4 is mounted in the form of a comb located along the racks and made rotatable around its longitudinal axis.

Drive 5 for lifting grip and drive 6 for moving the device are mounted on frame 1.

Cargo capture contains a beam 7, on which are mounted the hinged axles 8 with cargo-carrying strips 9 fixed on them. The hinged axles are installed in places of cargo laying parallel to the beam 7 with the possibility of rotation relative to the beam by 90 °.

The beam is rotated around its longitudinal axis from the actuator 10. One of the fixed-n '-Each axis 8 of the slats has slots 11 for engagement with a clamp 12 mounted on the beam. The clamp is pressed to the bar 9 by the spring 13 and is outputted from the sockets 11 by means of an electromagnet 14.

The extreme positions of the load carrying slats are limited by the stops 15. Freights are delivered to the warehouse by the live rolls 16.

The device works as follows.

On the roller table 16, which supplies the goods to the warehouse, a set of loads is accumulated. Depending on which side of the rack is to be loaded, the empty grip 4 removes the latches 12 from the slots AND of the load-carrying strips 9, and the bars, under the action of their own weight, rotate 90 ° relative to the beam as it rotates in the direction of the loading racking shelf to the stop 15. Capture It descends slightly below the level of the rollers mounted on the frame of the roller table by means of the uprights, the load carrying Ilanks are pushed under the weights and removed from the roller table. The gripper with weights rises to its highest position and is installed in the envelope of the frame 1 of the device.

The device moves to the loading rack, lowers the grip to the level of the given rus, enters the racking into the rack at the level of the specified rus, and lowers the weights on the racking shelf. The empty grab is then removed from the rack, and the device returns to the roller table for the next set of loads. Unloading the racks is done in reverse order of loading.

When selectively laying cargo device works as follows.

According to a given program, only those electromagnets 14 are included, whose location on the gripper corresponds to the empty places on the shelf of the rack. When the beam 7 is rotated around the longitudinal axis, said electromagnets pull the latches from the sockets of the load-carrying strips, which, under the action of their own weight, remain in a horizontal position. The remaining load-carrying strips held by the latches are rotated with the beam to a vertical position. On the roller table 16, for example, loads are accumulated with the help of cut-offs. So

This means that the arrangement of these goods corresponds to the empty places on the shelf of the rack. The horizontally supported load carrying gripping bars are inserted under these weights, removed them and loaded into the rack in the same manner as described above.

If necessary, the selective removal of goods from the shelf shelves according to a given program due to the rotation of the beam

the gripping and turning on of electromagnets of given clamps are set to horizontal horizontal position in the direction of the unloaded shelving shelf certain load-carrying gripping bars. I will eat

goods from the shelf and their laying on the roller table are made similar to loading, but in reverse order. Thus, the device can not only carry out batch stacking of uniform or heterogeneous goods in the racks, but also carries out their selective stacking or removal from the shelves for shipment from the warehouse in accordance with the received order.

In this case, the device can produce the specified operations both with single loads and with sets of loads.

The options described above for the construction of devices are preferable for practical application. However, there may be other design options. For example, the device may be of the portal, bridge, suspension or floor type. The frame of the device can have movement both across, and along racks. Vertical guides can be made telescopic or folding according to the type of Jürnberg scissors. Load plates may have different

the configuration adapted to the form of cargo or the design of shelves of shelving. However, all of these options are not beyond the scope of the application and the claims.

The device can be used for servicing both stationary and mobile racks in warehouses with any assortment of packaged cargoes, as well as in warehouses of long loads.
