FLOW RACK STORAGE SYSTEM

The present invention relates to a flow rack system, in which the goods to be stored are housed on roller bases in shelves equipped with rails are. Used to empty such systems or to remove a loaded castor base from the shelf one conveyor vehicles, e.g. forklifts, passing through the Drive through the rows of shelves and their lifting fork in front of the desired Shelf from which a loaded castor base is removed is to be positioned. On the forklift of the forklift there is a movable grapnel pick-up device attached, which enables the pulling out of a castor base.

Because the individual shelves have sloping rails are provided, on which the trolleys run, there must be Ansäiäge at the end of the shelves that can be driven over the end of the rail and thus a falling out of the castor base reliably prevent from the shelf. On the other hand, it is easy to see that the attacks are a removal make the roller base from the shelf more difficult, especially since it is desirable that the stops are rigid and not ■ to be swiveled away. So you can't avoid the Removal of the castor base to lift it over the stops when removing it.

The applicant has already proposed to use a device which has two inside the rails of the shelf in the Has rollers arranged in the area of the stops, which are free on a common shaft in planes parallel to the rails are rotatably arranged, wherein the two shaft ends are mounted in lateral link guides, which allow a parallel displacement enable the shaft while lifting the rollers at the same time. With this solution, however, you cannot come without the conveyor vehicle attached ram, which the parallel displacement of the shaft in the link guides when the conveyor vehicle is coupled cause.

A similar solution that the applicant has already proposed has, and which is a bit simpler and also cheaper, provides that on the transfer device, namely on the shelf opening facing end of the same rollers are attached, which are freely rotatable on a to the displacement direction of the takeover

device vertical shaft are mounted, the ends of which protrude beyond the rollers and form guide pins that are in the area The guideways attached to the shelf opening work together and thus raise the roller bases beyond the stops enable.

It is the aim of the present invention to overcome the problem of lifting a caster base outlined above the attacks can also be solved in a much simpler way, without any additional moving parts being provided that could give rise to disruptions.

The invention is based on a flow rack storage system type mentioned at the beginning, with a along the removal

ssite of the shelves movable, with a takeover device equipped conveyor vehicle for emptying the shelves, in the area of the rail end there are stops preventing it from being driven over, against which one is in front the wheels of the roller bases lying cross brace of the same rests. Such a system is characterized according to the invention characterized in that the stops are attached set back by a certain amount relative to the rail end, and that the end piece of both rails is provided with a hump-like elevation beyond the stop.

An embodiment of the invention will be described in more detail below explained. On the accompanying drawings show:

3-7 schematic side views of the shelf compartment end and of the transfer device in different phases of the removal of a loaded castor base.

From Fig.l is the basic structure of a flow rack visible in the detail. There is a storage rack, which is used to hold trolleys loaded with goods 1 2 is determined. The frame has vertical support beams 3, which are used to support horizontally extending Cross members 4 are used. On the cross members 4 are rails 5 which have a slight slope in the direction of the arrow P, so that the roller bases 2 endeavor to automatically move towards the removal opening of the shelf compartment located on the left in FIG roll. Stops, which will be discussed in more detail below, prevent the end of the rail from being driven over.

There is a conveyor vehicle along the removal openings of the shelves, For example, a forklift truck, movable, of which only the upper part of its mast is shown in Fig.l is. This carries a height-adjustable platform 8,

709824/030 5 - * -

on which a transfer device is mounted. This owns a laterally displaceable part 9, which is attached to the shelf exit standing roller base is slidable.

The more detailed formation of the rail track in the shelf can be seen from Fig. 2, in which, however, only the removal-side end of the same is shown. Laterally against the outside of the two rails 5 and 5 ¹ , a stop, generally designated 10, is attached. Each of the stops 10 has an upwardly projecting part 11 beyond the surface of the rail 5 or 5 ', which part 12 is attached to a carrier running parallel to the Schiaae. The latter is mounted in a sleeve 13, whereby means can be provided which, within certain limits, allow resilient displacement of the part 12 with respect to the sleeve 13 in order to dampen a shock caused by a rolling base on the stop part 11.

The stops 10 are set back by a certain amount compared to the end of the rails 5 and 5 '. Beyond the stop part 11, the end of each rail 5 or 5 ^{1 is provided} with a hump-like elevation 14.

3 to 7 is a schematic side view of the end of the rail track of a shelf as well as a takeover device located in front of it. On the rails 5 are a number of roller bases 3 with a load 1 are loaded. In the illustrated embodiment

709824/0305 - 5 -

the roller bases 3 have a load-bearing platform 3 ′ which is stranded with four rollers 15. These are set back with respect to the end faces 3 ^{11 of} the platform 3 ¹ / and on the end face 3 ^{11 of} the platform 3 ^{1 of} each roller base there is a cross member 16 which protrudes downwards.

The transfer device has a schematically indicated frame 17 on which the displaceable part 9 is mounted. from the latter, only the most essential part, namely an endlessly revolving conveyor belt 18, is shown.

In the situation according to FIG. 3, the conveyor vehicle has just finished created in front of the shelf and the movable part 9 with the conveyor belt 18 -was between the rails under the front part of the roller stand ready at the shelf opening 3 inserted. The caster base 3 rests with its front cross member 16 against the stop part 11. According to Fig. 4 The castor base 3 with its front cross member 16 now becomes lifted over the stop part 11 by lifting the entire takeover device slightly. The actuation then takes place of the conveyor belt 18, so that the roller base 3, which now rests on the conveyor belt 18 with its traverse 16, extends pulled out of the shelf. The rear wheels 15 roll while doing this on the rails 5. This phase is shown in Fig. 5. It can also be seen there that the rear wheel 15 is now approaching the stop part 11, so that it will soon be blocked the pull-out movement by hitting the rear cross-member of the roller base 3 on the stop part 11 would be expected.

_ 6 709824/030 5

The purpose of the hump-like elevation 14 at the end of the ski 5 or 5 ¹ is to prevent this. As can be seen from FIG. 6, the rear wheel 15 comes into the area of the elevation 14 shortly before the cross member 16 comes to rest against the stop part 11. By further pulling out the castor base 3, the rear wheel 15 runs onto the elevation 14, so that the cross member 16 is guided over the stop part 11 (dashed lines in FIG. 6). Now the roller base 3 can be pulled further onto the take-over device without hindrance, the rear cross member 16 also coming to rest on the conveyor belt 18 after the rear wheel 15 has completely passed over the elevation 14. This can be lowered again, for example in order to take up a second roller base 3 directly afterwards. After one or two roller bases 3 have been loaded onto the transfer device, its displaceable part 9 is retracted again and the conveyor vehicle can transport away the transferred loads.

It is essential that the elevation 14 protrudes over the surface of the rails 5 or 5 ¹ by an amount which is greater than the effective part of the stop 11. It should also be noted that the arrangement of the stop part 11 opposite the elevation 14 with the Distance between cross member 16 and wheel 15 corresponds. If these conditions are met, the takeover of a caster base can take place in the simplest and fastest way without any additional moving parts, be it on the shelf or on the takeover device, being required.
