DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method for loading with several layers of goods a storage and transport rack, and respectively for unloading it, wherein goods which arrive on a conveyor are transferred during loading into a rack, for example a cart-rack, and respectively, during unloading, the goods are transferred from it, the rack being fixed to a predetermined station for the duration of the loading or the unloading. The invention also relates to an apparatus for carrying out this method.
There are known apparatus by means of which a cart-rack, for example one for milk cartons, can be loaded in such a way that a quantity of milk cartons which fit on one storage level of the rack and are situated on a suitable flat support or are placed in a separate package are transferred to the storage level by pushing by means of, for example, a hydraulic cylinder. By adjusting either the height position of the rack or the height position of the level on which the goods arrive and from which they are pushed into the rack, the different levels of the rack can be loaded. Thereafter the loaded rack can be rolled away and a new cart-rack can be brought in its place. In the system in question, however, a considerable number of stoppages are caused because the replacing of the cart-rack takes its time and the rest of the system is idle during that time. In addition, applying such a system also to unloading is difficult.
The object of the present invention is to provide a method and apparatus by means of which the above-mentioned problems can be overcome and by means of which not only the loading of a storage and transport rack but also its unloading can be achieved in a manner optimized with respect to the use of time.
For this purpose the invention applies an intermediate storage device which is equipped with a vertical transfer device for receiving the goods in layers and from which then the entire formation of goods can be pushed into the rack at one time. A vertical transfer device of this type is prior known from, for example DE patent application No. 2,131,179. It utilizes in connection with the storage of goods a lifting device moving on rails, in which the layers of goods are stacked one on top of the other and which can then place the entire formation into the appropriate storage rack, or respectively take a formation out of the rack. What is concerned in the present invention is a stationary intermediate storage which can be loaded, or respectively unloaded, while the loaded, or respectively unloaded, rack is being replaced.
The method and apparatus according to the invention are characterized in that the goods are transferred from an intermediate storage by horizontally movable plate-like members that are being pushed in one push, but slightly staggered so that the lowest layer of goods is transferred into the shelf-less rack first.
The invention is described below in greater detail with reference to the accompanying patent drawings, in which
FIG. 1 depicts a simplified side view of an apparatus according to the invention,
FIG. 2 depicts the same apparatus in section A--A of FIG. 1,
FIG. 3 depicts an apparatus according to the invention specifically applied to the unloading of a cart-rack,
FIG. 4 depicts the apparatus according to FIG. 3 in section C--C of FIG. 3,
FIG. 5 depicts section B--B of the intermediate storage apparatus seen in FIGS. 2 and 4,
FIG. 6 depicts an intermediate storage apparatus for goods which are not in packages, and
FIG. 7 depicts the loading stage for such goods, corresponding to FIG. 1.
FIG. 1 depicts an apparatus 1 in which the goods to be loaded, in this case bottles 2 packed into a group, arrive at the loading site on a conveyor 3. The cart-racks 9 to be loaded arrive at the site on a conveyor 10 and stop at the loading place. In the immediate vicinity of the conveyor 3 there is an intermediate storage 4, and those edges of it which are parallel to the travel direction of the conveyor 3 have endless conveyor chains 12, which serve as lifting/lowering devices and in which there are
