LIFTING FRAME

assassssasssasssa

for picking up and transporting roller bows with stored goods.

The innovation relates to a so-called lifting frame, which is connected to two Ketzen a commercial crane is hung and on the lower side member has a number of powered takeover devices - and over one Shelf storage is lowered from above into shelf aisles to be there in defined heights - predeterminable numbers of roller bows contained therein To move piece goods horizontally, ie. for example for outsourcing from the shelf into the lifting frame to move them together to your raising the lifting frame and moving the crane to any point bring off the shelf.

Conversely, for example, for storage - other Rollbugeln with stored goods - taken from other locations outside of the bearing in the lifting frame, pulled up and moved with the crane _v to be lowered in a specific aisle at a preselected seat and pushed there by the lifting frame in the shelf «

»I.

The intended purpose of the innovation is to use only one lifting frame -

all spaces in a ragal complex and all designated spaces outside to be able to approach the racking system and any number of different

Rolling bracket groups with general cargo contained therein - only through a horozontal «

move - ON = resp. OUTSOURCING and in-house - without a

Moving - to be carried below the crane runway, e.g. to feed machines. I.

The lifting frame is a horizontal frame with the upper longitudinal members on | two fixed - or mobile electric hoists of a single girder crane bridge - respectively. | to an electric hoist with two ropes, a special mobile trolley on one ^! Double-girder crane bridge, possibly equipped with an additional slewing ring, or the lifting carriage itself is a storage and retrieval unit moving on the floor or on the shelf.

An essential feature of the Hubrahmsns is the closed, sometimes also open at the top, stiffened in the corners frame, with two suspension devices in the upper longitudinal beam, respectively. in the lateral guide beams, as well as the paired upper and lower guides on all sides - and the horizontal lifting frame girders that are fixed to the lower side girder and arranged perpendicular to it with the driven take-over devices on both sides, as well as the hooks additionally built into the lower side girder for attaching loads.
With larger lifting frames, this is also designed as a double frame.

In comparison to the present innovation, for some time now -

in particular - long goods storage - known in which a storage and retrieval unit moves on top of a cantilever racking system and can lower a guided lifting beam with two telescopic forks into the rack aisles.

With this type of storage - cassettes - are required for the recording

of the stored goods, which in some cases also have to be self-supporting, if the shelf stands are only available on the two outer sides of the shelving system

The main disadvantages of this Lagsrsystemes are the numerous and expensive cassettes and the required complicated and very expensive shelf operator with the lifting beam and the also very expensive telescopic fork ^ as well as the necessity that each cassette to be picked up only go under, -lifted - and only then can be withdrawn. When dispensing a cassette, the process is reversed and therefore requires a large amount of additional -

common control commands.

Another disadvantage is that the cassette dimensions have the greatest length and

limit the largest width and the maximum weight of the stored goods and that e.g. no longer; Parts can be included in the warehouse.

In addition, the storage and retrieval system moving on the shelf cannot be used in an external location

be approached. Additional, expensive ones are required to reach these areas and complex facilities such as cranes, shuttle cars, roller conveyors, etc.

often with additional personnel costs - required.

The function of the innovation is to nätee-r on the basis of exemplary embodiments

be explained.

In the drawings the features of the innovation are shown schematically,

In Fig. 1 and in Fig. 2 - is in a front view and in a section of the shelf aisle seen from - and in Fig. 3 and in Fig. 4 - is in the associated Floor plan and in section - a lifting frame shown as an example and in a simplified manner.

With 1 are the lower longitudinal members, with 2 are the vertical guides. Beams, with 3 are the upper longitudinal beams and with 4,4a are the Designated corner plates. In general, steel profiles, respectively. Light metal profiles, occasionally also folded sheet metal profiles - to a bend = and torsion-resistant frame composed. Usually the frame as a lifting frame is welded as a steel structure as a whole, with greater lengths Non-drawn control pulses apply. For larger material lengths and unit weights, the lifting frame is manufactured as a double edge and is also shown in the following drawings as a double frame. In the embodiment of the single frame, there are the lower longitudinal members and the upper longitudinal members 2 - from only one torsion-resistant profile and are not shown separately.

On the lower longitudinal members 1 are in the shelf division t perpendicular to it horizontal lifting frame girders 5 are firmly attached still intermediate carrier, respectively. Intermediate pieces 23 installed.

In Fig 5 it is shown that the length of the lifting frame support 5 of the shelf aisles « Width - b - and thus the longest roll bar 9 used in the shelving system - corresponds.

In Fig. 1, in Fig. 2 and in Fig. 4, the suspension of the lifting frame is schematic via for example - two pulleys 39 are shown. A 2/2 reeving is achieved, with half the rope forces and lifting speed = a sensitive approach ■ position - allow. In this case two pulleys * are attached to the upper longitudinal member 3 - as far out as possible - Pairs of supports 40 are used and a rope pulley 39 with roller bearings is inserted between them and held with a rope claw bolt 41.

-In the example shown, the two hoisting ropes 36 are each from one

Elsktrossilzug 42 with two speeds over the pulleys 39 - to

guided by a rope fixed point 45, and is also shown in FIG.

According to Fig. 1 and Fig. 2, in this embodiment, the two electrical

. ••, matt λ ·. a a '.: _#

Cable pulls 42 on both sides of a single girder crane bridge 43 laterally attached and not movable. Of course, both of them can Electric wire rope hoists, for example, can also be moved as lower flange trolleys.

On the crane bridge girder 43, respectively. on a frame for movable cats, According to Fig. 1 and Fig. 2 - a vertical guide profile is firmly attached to the outside, in which the lifting frame is guided in the uppermost position and is secured against rocking.

When the crane and the trolleys are moved, these guide profiles 44 Brought with little play over the guide profiles on the shelf and represent a direct extension of the guides when they match, so that is always between two guides when lowering the lifting frame.

In a special case in Fig. 1 and Fig. 2 in any application = Example shown that the lifting frame in the guide profiles 44 - up to both sides of the crane girder can reach - 45 and 46 * and almost Can extend over the span of the crane bridge, the electric cable = Trains are firmly built on the crane bridge.

In other applications, not shown, shorter lifting frames any two cats can be struck and moved.

Likewise, lifting frames (not shown) can be attached to a special trolley with a Electric hoist can be hung on two ropes, which may have an additional rotating device.

In the right cold of Fig 2 - is an alternative for another Application shown that it is often useful to jack up the crane bridge so that the drawn-in lifting frame above the crane runway girders 46! lies.

In Fig. 2 is at the same time a schematic for another application example also shown that in, respectively. A number of hooks 37 are permanently installed between the lower longitudinal members 1, for example by means of brackets 36 and do not protrude under the side members.

For another application example, round iron hooks 37 a - directly in the binding plates 24 - welded in.

A lifting frame equipped with hooks can be removed from the shelf use it like a standard lifting beam.

In Fig. 3 is a plan view of the lower longitudinal member 1 - simplified the structure of the transfer devices is shown, which is based on the detailed drawing will be described later.

The number of takeover units is based on the shelf and the largest storage length 1. The clear height h of the lifting frame is determined by the

highest roll bar to be taken up.

In FIGS. 5 to 9 it is shown by way of example that the lifting frame supports 5

with a small gap on the shelf supports 6 of the same type vertically are passed and in the height correspondence a suitable extension of the beams 5 and 6 - represent.

In Fig S it is clearly explained that the shelf supports 6 and 6 ^{1 of} the opposite -

shelf sides do not have to be at the same height because the transfer devices in the lifting frame for the control pages links 6 and

Right 6 * are driven separately. In Fig. 5 it is also shown that in random order one after the other

from the left side of the rule - flat and long roll bars 9 - and from the right

Shelf side -high and short Hollbügel 9 * are included in the lifting frame,

where any intermediate mass of the roll bar dimensions within a

Shelf systems can also be implemented. Only if the heights of the supports 5 and 6 are exactly the same as in Fig. 9 -

reach the Kettenrrdtnöhfner θ of the driver chain 7 during a movement Rollbar carrier 10 and can therefore din rollbar 9 from the shelf «

Pull the beams 6 onto the lifting frame beams 5 in the direction of the arrow.

In Fig. 7 and Fig θ is on a larger scale in cross section and in the associated Floor plan shown as an example that basically the roll bars 9 and 9 *, which are opposite in the Hegel, are pushed in offset by 180 °, This means that the roll bar drivers 10 and 10 * are on different sides.

The right and left side of the shelf is served independently of one another with its own driver chain 7 or 7 * bB, whereby, according to the drawing, the front driver chains 7 only take up the left roll bar 9 and the rear driver chains 7 ¹ only take up the right roll bar 9 ·.

The drive motors 13 and 13 'act independently of one another on the drivers « Chains 7 and 7 *. Switching on the drive motors 13 and 13 'at the same time is prevented and monitored by the electrical control.

On the lower side member 1 of the lifting frame are according to the clear width - 1 - a number of such similar takeover devices in analog Shelf clearances - t - available.

So that, in the generalized sense of the innovation, it is possible to use any preselectable number of roll bars 9 at the same time - each driver chain 7 or 7 * is, for example, driven with an individual drive 13 or 13 '.
The same purpose can, as indicated schematically in Fig. Β right - with

a continuous shaft 15 * and the electromagnet clutches built on it 16 'Reach via the drive sprockets 12 *. In the Fig are drawn to the right and left of the lower longitudinal beam 1 - alternatively both drive options - left with single drive and right with continuous drive Shaft and a motor. In a practical use case it will be from case to case Case decided which type of drive is more suitable. In the latter case, on both sides of the lower longitudinal girder 1 - one continuous on each side Shaft fastened with pillow block bearings and each with a drive motor 13a, 13a each via a drive chain 14, 14 '- driven.

Depending on the application, the drive sprockets 12 and 12 'can also be used. Put them together in groups and drive them together. Switchable solenoid clutches are used as shaft couplings.

According to the principle of innovation, predetermined numbers of roll bars 9 as an example taken from the left shelf side drawn in Pig 9, ie. with the transfer devices - carrier chains 7 on the lifting frame carrier S to be pulled. For this purpose, the corresponding drive sprockets 12 - (according to FIG. 7) are switched on at the same time, that is to say driven. The first following chain drivers θ come when moving in the direction of the arrow behind the roll bar driver 10 and begin the roll bar 9 to the lifting frame to pull. The chain pulleys 11 are pre-built so that the ascending Chain driver θ produces the largest possible horizontal component, ie. that he is only in the last third of the chain pulley 11 at the Rollbugelmitnahmi 10 bumps.

In Fig. 10 is a front view analogous to Fig. 9 - on the lifting frame. Carrier 5 is shown in simplified form that only the driven driver chains 7

the roll bar driver 10 can take up, whereas the stationary ones second driver chains 7 * on the other side the horizontal movement do not interfere with the roll bar 9.

In the rest position, all driver chains 7 and 7 * are in that position

held, in which there are no 8 or 8 * chain drivers on the front-mounted

Chain steering wheels 11 and 11 * are located, which are used in the vertical process of the Lifting frame against the Rollbugelmitnehmer 10 and 10 'could hit. The drive motors are in a defined position (not shown)

13 and 13 * stopped so that all chain drivers 8 and 6 * are always are in a very specific starting position, thus at the same time and to evenly pick up the corresponding rollbar carriers «

The deflection sprockets 11 are with roller bearings 18 and bearing bolts 17 the

into the chain wheel carrier 25 according to FIG. 10, which is firmly attached to the longitudinal member 1 firmly inserted, respectively. shrink wrapped.

.. B} .tt .r β -.:- η

In Fig. 11 is an example in a cross section through the lifting frame

shown that the recorded Rollbügal 9, respectively. groups from coming to a standstill in the central position on the lifting frame.

Dia roll bars, for example, have a on the inner underside Scarf ta .oppan 19 in the middle of the fiollbügals 9. In the lifting frame support 5

A limit switch 2o is built in, which in the movement of the Rollbügais from

Switching knobs 19 is actuated to switch off the drive motor 13 or 13 '. The limit switch So has two cold points and is therefore independent of

the direction of movement of the rollbar.

In the same FIG. 11 it is also shown how each roll bar 9 in the lifting frame between two chain drivers θ and θ a and the roll bracket drivers 1o and 1ob is held with little play.

The number and distribution of the chain drivers θ on the driver chains 7 takes place differently from case to case and is the respective roll bar ■ Adjusted lengths in a specific rack warehouse.

According to the innovation, roll bars of different lengths can be installed in the lifting frame can be recorded in groups. In the case of short stored goods, several groups of roller brackets can be pulled into the lifting frame next to one another. Used in this way, roll brackets with storage contents can be placed next to one another in the Pick up the lifting frame in order to only then move to a storage location outside the control room and then all of the roller bars in the lifting frame together deliver at the same time. Conversely, the lifting frame can be loaded with different goods for storage, which are then distributed on the shelf. Universal application is thus possible in the sense of the innovation, and given. For example, long goods can be picked up with the same lifting frame which fills the entire length of the lifting frame and lies on many roll bars. In the other extreme case, they are in the same Hubrahman for example - pool pallets with stored goods have been drawn in close to one another, “oak is stored anywhere on the GUICVl) shelf, or handled in some other way will*

Roller brackets with plates and roller brackets with tall items can also be used in one and the same lifting frame are included.

In the same application example, FIG. 12 shows the delivery state of one of the Roll bar 9 from the lifting frame support 5 to the one on the right in the drawing Shelf support 6 * or. to a similar carrier of an outdoor system. In the sequence of movements shown, the first chain driver 8 goes under the front roll bracket driver 10 on the chain pulley 11 a after down away. The chain driver B b next but one moves to the rear one

Rollbügelmitnahmgr 10 b and takes over the further transport.

In FIG. 13, the step-by-step limit switch-off is for the same exemplary embodiment of the drive flotor 13 - after the release of the Rollbügiil 9 from Lifting frame support 5 - on the support 6 · - shown in simplified form. At the ends of the roll bar 9, a further switching edge 19 b is attached, for example on the inner underside.

During the illustrated movement in the direction of the arrow to the right, the Switching knob 19 b on the front limit switch built into the lifting frame support 5 21, the drive motor 13 - for example by a pole change, or another shutdown switches to a lower speed and thus moves the roller bar in the fine input - until the switching edge 19 b the second limit switch 22 is actuated, which switches off the drive motor 13 and immediately a differentiated chain return transport in the opposite direction of rotation until the rest position of the chain driver B performs to there to be stopped by another limit switch.

In the drawings 3ind simplified - mechanical limit switches - shown. In some cases, non-contact limit switches, initiators, light barriers, etc. are also used. used.

The delivery of roll bar groups 9 with the same driver chains 7 in the

other direction to the LEFT - takes place analogously in the manner described and

Way, only the anti-life blower gets 13 βΐηβ a different direction of rotation. Similarly, according to FIG. 7 and FIG. 8, the roller bar groups 9

from the illustrated left shelf support 6 with the other driver chains 7 picked up and released again in a corresponding direction.

The limit switches 21 and 22 are on both sides of the lifting frame support 5

appropriate.

In Fig. 14 (14 a) to Fig. 17 (17 a) are two views in some Embodiments of various chain drivers B a to B d shown in simplified form, which have a one-sided structure as a common feature - outside above - have.

In Fig. 14 (14 a) each chain driver B a is formed from a number of commercially available rectangular driver plates by layering and is assembled and riveted to form a package using commercially available rivets of a duplex chain. This version has the advantage of being cheap too because no special parts are used.

In Fig. 15 (15 a), the chain drivers B b are steel angles with a * Upper horizontally lying thighs and are called normal outer limbs

riveted into the driver chain 7 '\ 7'). The WinkBl is made of folded sheet steel in the same thickness as the chain links or made of drawn steel «* profiles with a reinforced horizontal leg.

In Fig. 16 (i6 a) the chain drivers are 8c steel U-profiles with two vertical flanges and are like normal links in the Driver chains riveted together. The U-profile is made of folded sheet steel in the material thickness of the chain links, or made of drawn steel profiles with reinforced vertical flanges.

According to Fig. 17 (17 a), the chain drivers are 8 d - high rectangular plates roughly in the form of Fig. 14, riveted in as normal chain links, to which previously a steel U-profile with vertical flanges and horizontal Bridge was firmly applied. In place of this U-profile, a high plate made of solid material is put on, for example - riveted.

In any exemplary embodiment, the statically load-bearing steel structure of the lifting beam girders 5 on the side girder 1 of the lifting frame is shown schematically in a cross section, in this example the lower side girder 1 consisting of a rectangular box girder profile. For structural reasons, e.g. in order to create more space for the driver chains 7 and 7 ', it is often expedient - to insert intermediate supports 23 or short spacers 23 a firmly between the lifting frame supports and the lower longitudinal support 1. For double frame vertical tie plates 24 are, BEZW between the lower longitudinal girders ~. 1 Non-marked outcrossings welded in for stiffening.

In Fig. 19 and in Fig. 20, for the same embodiment example, in a cross Section and in the associated front view (section) - the structure of the

pre-built deflection sprockets 11 shown in simplified form.

On the side members 1 - or on the side members ,, 1 of the lifting frame- become

both sides of the lifting frame support 5 - so-called chain wheel support 25 put on, depending on the requirement - flat iron - angle - or U-profiles sindι in which at the outer ends the deflection sprockets 11 with welded laying bolts 17 are held. (*> · "·) Ti ^. 1«)

Further deflection sprockets 11 u - or the drive sprockets 12 are as Tensioning wheels for the driver chains 7 and 7 'carried out. Chain guide strips 26 are used to support the driver chains 7 and 7 '

for example with stud bolts 27 on the sprocket carrier 25 adjustable attached.

In Fig. 21 to Fig. 24 is for an application example with a double frame and in two views and two straightening - a lifting frame corner in principle

To this end, the guide beams 2 - and 2 are vertically attached to the lower side members 1 on it the upper longitudinal members 3 with the corner plates 4 and 4 a combined to form a bending and torsion-resistant double frame, sometimes together = · Welded between and on the guide beams 2 are additional cross members built-in. Further connections in the lower and upper longitudinal members are made with the binding plates 24 and 24 a - approximately at the same distance as the lifting frame members 5. The guide beams 2 are extended beyond the height of the upper longitudinal beams 3, by larger distances in the guides and thus smaller ones Get executives.

All guide rollers 29 are ball bearings and are, for example, with Eccentric bolt 3o readjusted. The roller blocks 31 are adjusted 32 with pressure screws. The guide units are placed on a further transverse profile 33 and

easily interchangeable as a whole.

In Fig. 25 is shown in another embodiment that instead of the upper longitudinal member 3 - between the hanging boxes 4B - one or more Tie rods 47 are used. In the example, a tie rod 47 is passed through the suspension box 48 and is attached to a normal crane hook there. This solution is ideal if the lifting frame should not be permanently attached to the crane.

In Fig. 26 and Fig. 27 it is shown in another application example that the Pulleys 39 are installed within the guide support 2. In this case, the upper longitudinal beams are omitted and the lifting frame therefore becomes one after open at the top - U-shaped frame.

In the same example it is shown according to FIG. 27 that the

Guide rails 29 are set to the outside that this example lead directly in the vertical girders of a shelf construction.
