DESCRIPTION:
BRIEF SUMMARY
The invention concerns a device for storing pallets and removing them from storage that has, first, a number of shelves erected along lanes and consisting of beams on the front and of brackets positioned at intervals one in front of the other and one above the other that engage the bottom of shoulders on the front of the self-supporting pallets that are to be stored and, second, a lifting-and-displacement mechanism that accepts each pallet at the front, travels along a shelf and lifts and displaces the pallet in a lane and stores and removes the pallet.
The utilization of space is of considerable economic significance in storage devices, especially stacked-shelf devices, in which a number of pallets are stored one above another in the shelving. Known devices for storing pallets and removing them from storage actually take up an undesirable amount of space within the shelving at the expense of storage capacity. The lifting-and-displacement mechanism between each pair of shelves in such devices consists of pivoting arms (German AS No. 1 177 553 & German Pat. No. 2 725 789) or of telescoping parts (German OS No. 2 400 871 and German OS No. 2 725 789) that can be moved into the shelving and that underpin the pallet itself. Such a mechanism requires free space for the device for storing pallets and removing them from storage. This space is in addition to the dead space already in existence between the vertically positioned shelving compartments that derives from the path needed to deposit and lift the pallets and includes a margin of safety. Still another component of the lifting-and-displacement mechanism is the carriage that underpins either the pallet or extensions on the front of the pallet. These carriages travel into the shelving along tracks below and projecting beyond the shelf brackets that underpin the pallets (German OS No. 2 324 907). This version of the storage device, which employs standard pallets, also necessitates a free space between the shelving compartments for the pallet-transport carriages. Another embodiment (German OS No. 3 032 050) employs pallets that terminate at a distance from the tracks and have extensions or supports projecting over them. This decreases the amount of space necessary for the device for storing the pallets and removing them from storage to the path traveled by the pallet-transport carriage. The interval between the shelving compartments can accordingly be reduced to the path needed to deposit and lift the pallets, including the margin of safety. Nevertheless, this version still incorporates areas of shelving containing the path traveled by the transport carriage, at the cost of storage capacity. All known devices for storing pallets and removing them from storage are also comparatively difficult to access. This makes them difficult to repair.
The present invention employs the state of the art outlined in the foregoing as a point of departure. The invention is primarily intended to optimize the storage capacity of a device for storing self-supporting pallets in the shelves that are an essential component of the device.
This object is attained in accordance with the invention in a device for storing pallets and removing them from storage that has, first, a number of shelves erected along lanes and consisting of beams on the front and of brackets positioned at intervals one in front of the other and one above the other that engage the bottom of shoulders on the front of the self-supporting pallets that are to be stored and, second, a lifting-and-displacement mechanism that accepts each pallet at the front, travels along a shelf and lifts and displaces the pallet in a lane and stores and removes the pallet in that the device consists of two matching bridges that can be synchronically lifted, each of which leads along a single bracket on the rear of the shelves, which are in the form of extensions and of carriages that can be displaced along the bridges at an angle to the shelves and have a platform that extends out into the storage device, with the projecting length of
