Description

Modular storage shelving system and load handling vehicle

The invention relates to a modular storage shelving system comprising a plurality of modular shelf units, each of which has a plurality of shelves and shelves offset in the height direction. According to the invention, in the shelves of the shelving units, mutually passing channel structures are provided, which permit the passage of a load-receiving vehicle accommodated in one of the channels between shelves arranged at the same height of different shelving units. The invention further relates to a load-bearing or rail vehicle for receiving in a hollow profile rail, a family of at least two or more in the longitudinal direction one behind the other arranged in a hollow rail rail vehicles and a group of at least two or more arranged in the adjacent hollow rail rail vehicles. Hollow profile rails may also be referred to as channel profiles. They realize a lane for the rail vehicle according to the invention.

A classic logistics warehouse shelving system is described in DE 101 42 395 Ai. Accordingly, there is a storage area of different shelves arranged side by side, wherein between each two rows of shelves a rack aisle is formed. The individual shelves are anchored to the floor and ceiling. On the opposite ends of two opposite shelves transversely extending, suspended from the ceiling rails are provided on which individual vehicles can be moved along a rack aisle. The satellite vehicles of the storage and transport system described in DE 101 42 395 Ai drive in the rails along the front of the shelf and can deliver stored goods transversely to the direction of travel in a shelf or record it. In order to increase the capacity of the storage and transport system, DE 101 42 395 Ai proposes to increase the number of satellite vehicles. In the storage and transport system according to DE 101 42 395 Ai, one third of the surfaces of the storage area remain unusable as a rack aisle for storing stored goods. Increasing the number of satellite vehicles is a very costly approach to Increasing capacity, especially as low utilization of the storage system, many of the vehicles remain unused, but their acquisition costs do not disappear.

It is further an object of the present invention to provide a load-bearing or rail vehicle for receiving in a hollow profile rail of a particular storage shelf system according to the invention, with a simple way to achieve a safe, fast and accurate positioning of cargo.

This object is solved by the subject-matter of claims 1, 15, 20 and 21. According to claim 1 there is provided a modular storage shelving system comprising a plurality of modular shelving units. Each shelf unit of the plurality of modular shelving units has a plurality of shelf legs as well as a plurality of shelves offset from one another in the height direction and supported by the respective shelf legs of the shelf unit. The modular storage rack system is thus composed of a plurality of individual shelving units, each of the shelf units in the vertical direction offset shelves, which are supported by legs of the respective shelf unit. The shelves each have a first channel structure or longitudinal channel structure with at least two in the longitudinal direction, in particular parallel, extending longitudinal channels or channels, which extend continuously from a first, preferably front, shelf bottom edge to an opposite second, preferably rear, shelf bottom side open. The at least two channels are preferably bounded in the transverse direction by webs. The webs define above the channels a footprint for carrying stored goods. Preferably, a single shelf defines each a channel bottom surface in which the bottoms of the channels are arranged, and a set plane in which the footprint is defined by the upper edge of the web, wherein preferably set plane and bottom plane of each tray are arranged parallel to each other.

At least two of the modular shelving units are arranged adjacent one another in the longitudinal direction such that the shelves of the at least two shelf units are arranged in pairs at the same height and their channel structure in particular without interruption merge into each other to allow trespassing a housed in one of the channels load-carrying vehicle between arranged at the same height shelves. In the modular storage rack system, at least two, three, five, ten or more rack units may be disposed immediately adjacent to one another in a first direction or longitudinal direction, which is preferably parallel to the longitudinal direction of the longitudinal channels. In such a pairwise adjacent arrangement of modular shelving units, the shelves of the adjacent shelving units are preferably arranged such that a first shelf in a first shelf unit and a second shelf in a second shelf unit are arranged at the same vertical height. More of each several shelves per shelf unit are preferably also arranged in pairs in parallel at the same height.

In order to increase the capacity of a storage rack system, the number of modular rack units can be increased, which is much less expensive compared to the increase of satellite vehicles or the like. It may be preferred that the modular shelf units can be disassembled into individual parts, for example in the individual shelves, shelf wall and optionally components for cross-stabilization of shelf units, which can save the disassembled set to form a shelf unit to save space.

The use of shelves with a transverse channel structure in addition to a longitudinal channel structure opens up the possibility of a storage shelving system, in which a plurality of modular shelf units blockwise in the longitudinal and transverse directions together adjacent to each other and to access the shelves of each shelf unit at increased speed from four different directions. The use of longitudinal and transverse structures makes it possible to selectively access from the front, back, right or left to the footprint of a shelf of a shelf unit. It should be understood that the terms "front,""rear,""left," and "right" as used herein for simplicity are defined essentially by a freely selectable datum point, such as the (front) end of the storage system, and only the serve a simpler and more easily traceable reference to a first, second, third or fourth direction. Preferably, the longitudinal direction and the transverse direction are oriented perpendicular to each other. It is clear that an arrangement is provided transversely to the longitudinal direction, wherein, for example, transverse direction and longitudinal direction can intersect at an angle other than 90 ⁰ , about 6o ° or 45 ⁰ , respectively. The base of a modular shelf unit can be square or rectangular, in which case preferably transverse and longitudinal intersect perpendicular to each other.

The shelves each have a first channel structure or longitudinal channel structure with at least two in the longitudinal direction, in particular parallel, extending longitudinal channels or channels, which extend continuously from a first, preferably front, shelf bottom side to an opposite second, preferably rear, shelf bottom side open. A longitudinal channel forms a hollow profile rail. The at least two channels are preferably bounded in the transverse direction by webs. In particular, webs above the channels define a footprint for carrying stored goods. Preferably, a single shelf defines each a channel bottom surface in which the bottoms of the channels are arranged, and a set plane in which the footprint is defined by the upper edge of the web, wherein preferably set plane and bottom plane of each tray are arranged parallel to each other.

At least one rack unit may have at least two channels or hollow profiled rails which extend in the longitudinal direction over at least one, preferably at least two, in particular at least ten, longitudinal extension widths of the rail vehicle. Alternatively or additionally, at least two modular shelving units can be arranged adjacent to one another in the longitudinal direction such that shelves of at least two shelving units are arranged in pairs at the same height and their channel structure merge seamlessly, in particular, to transgress a rail vehicle accommodated in one of the channels between at the same height to allow arranged shelves. In such a modular storage racking system, at least two, three, five, ten or more rack units may be disposed immediately adjacent to one another in a first direction or longitudinal direction, which is preferably parallel to the longitudinal direction of the longitudinal channels. Further, each of several shelves per shelf unit are optionally also arranged in pairs in parallel at the same height. In this way, shelf units arranged next to one another can form common shelves and possibly a common channel system. With a preferably modular storage rack system can be arranged between shelves shelves avoided and thus achieve a very high utilization of a given storage area by transport channels are housed in the individual shelves modular storage rack units.

According to one embodiment of a storage rack system, at least one shelf has a second channel structure or transverse channel structure with at least two transversely extending, in particular parallel, transverse channels extending continuously from a third, for example, left, bottom edge side to the opposite fourth open, for example, right shelf edge side open. A transverse channel forms a hollow profile rail. Cross channels and longitudinal channels can realize intersecting hollow profile rails. A storage rack may have one or more rack units whose shelves are partially or all equipped with a transverse channel structure. The use of shelves with a transverse channel structure in addition to a longitudinal channel structure opens up the possibility of accessing individual shelves with increased speed from four different directions. The use of longitudinal and transverse channel structures or hollow profile rails makes it possible to access individual shelves optionally from the front, rear, right or left. It should be understood that the terms "front,""rear,""left," and "right" as used herein for simplicity are essentially defined from a freely selectable reference point, such as a (front) end of the storage system, and only the serve a simpler and more easily traceable reference to a first, second, third or fourth direction. Preferably, the longitudinal direction and the transverse direction are oriented perpendicular to each other. It is clear that an arrangement is provided transversely to the longitudinal direction, wherein, for example, transverse direction and longitudinal direction can intersect at an angle other than 90 ⁰ , about 6o ° or 45 ⁰ , respectively.

A modular storage rack system according to the invention is generally designated by the reference numeral 1 below. A rail vehicle is generally designated by the reference numeral 100 below. Hereinafter, the same or similar reference numerals will be used for the same or similar components.

Figure 1 shows schematically a modular storage rack system 1, which is composed of a longitudinal row in the longitudinal direction L of immediately adjacent to each other and attached shelf units 3 assembled. The shelf units 3 each have a rectangular base and four arranged at the corners of this base shelf legs 31. The legs 31 are connected at the upper end in the vertical direction V by a base plate 33 rigidly. In the lower region of the shelf unit 3, a base-side base plate 33 is provided near the storage hall footprint io, on which the shelf units 3 are anchoring-free. Each shelf unit 3 takes in the execution copies 5 shown in Figure 1 in the height direction staggered shelves 5 on.

If one considers the longitudinal rows 4 as a whole, then five longitudinally continuous levels are formed with respect to the longitudinal row 4 by means of the shelves 5 of the individual shelf units 3. The shelves 5 of the individual shelf units 3 are arranged in the shelf units longitudinal row 4 such that the shelves 5 of any first shelf unit 3 are each arranged at the same height in the vertical direction V as a respective shelf 5 with respect to the first shelf unit 3 in the longitudinal direction immediately before and / or immediately behind arranged second and / or third shelf unit 3. In the in Figure 1 (as in the FIGS. 5a, 5b and 6), the illustrated position of the transfer robot 90 can be used as a reference point with regard to the terms "front", "rear", "left" and "right". The transfer robot 90 is in the front end of the modular storage rack system. 1

In the case of the modular storage rack system 1 according to FIG. 1, in each case two fastening devices offset in the vertical direction V in the form of engagement elements 35a (rear) or 35b (front) are provided on the front side as well as on the rear side of each individual rack unit 3. The engagement elements 35a and 35b are shown larger in the detail view according to FIG. An upper engaging member 35 a, 35 b is provided in the vertical direction V at the level of the upper base plate 33 on the shelf unit 3. Another engagement element 35a or 35b is arranged in the vertical direction V at the middle height of the shelf unit 3.

A front engaging element 35b and a rear engaging element 35a are shown here in simplified form as elongated hook-like strips extending in the transverse direction Q. The front engaging member 35b has a vertical direction V upwardly facing projection and the rear engaging member 35a has a vertical direction V downwardly facing projection. The front (35b) and the rear (35a) engaging elements are complementary in shape to each other, that each shelf unit 3 can be connected to any other shelf unit 3 of the same type, wherein the fasteners 35a, 35b a relative movement of two connected shelf units 3 in the longitudinal direction L play or with little play. In addition to the illustrated form fit in the longitudinal direction L, the fastening devices may be complementary in shape in such a way that they provide a positive connection in the transverse direction Q between two vertically adjacent shelving units 3, which may be free of play or may have slight play, around two shelf units 3 arranged one behind the other in the longitudinal direction L. , which are connected to each other via a fastening device, also to secure a relative movement in the transverse direction Q.

In the detail view of the upper end of a shelf unit 3 shown in FIG. 1 a, a (right-hand) support bar 37 is shown, which together with an unspecified provided opposite (left) support bar, which is attached to the opposite shelf units 3 of the shelf unit, can provide a holder for a shelf 5.

The transfer robot 90 may be configured with a rack 91 configured to lift one or more rack units 3, and a carriage 93 of the transfer robot 90 may be connected to the frame 91 to lift the frame 91 and the rack unit 3 held thereon. It is also conceivable that gripping arms of a transfer robot 90 can grasp a preferably emptied rack unit 3 and can attach it to the frame 91 of the transfer robot 90. The transfer robot 90 can carry on its frame 91 hinged shelf units 3 with it when the wagon 93 the transfer robot 90 go. Thus, a modular storage racking system 1 can be reduced or extended by rack units 3.

In comparison with the modular storage rack system 1 shown in FIG. 1, which comprises only a single row 4 of rack units 3, it is usually possible to provide numerous rows 4 standing next to each other, which will be described in more detail below (FIGS. 5a, 5b and 6) , In order to secure in the transverse direction Q side by side arranged shelf units 3 against a relative movement, further (not shown) fastening means may be arranged on the left and / or right side of the shelf unit 3.

Figure 2 shows two in the longitudinal direction L immediately adjacent to each other arranged shelves 5. A shelf 5 preferably has a width of at least 10 cm and / or at most 200 cm, preferably between 20 cm and 100 cm, in particular for receiving stored goods with a width of about 15 cm. A shelf 5 preferably has a length of at least 10 cm and / or at most 200 cm, preferably between 20 cm and 100 cm, in particular for receiving stored goods with a length of about 50 cm. The two shelves 5 are substantially identical except for the side shelves which are arranged on the rear shelf 5 on the left and on the right and which form a safeguard against falling stored goods 2. Each shelf 5 is integrally formed. Preferably, a shelf 5 can be made as a plastic part, for example as an injection molded part, continuous casting or the like. The shelf 5 has (like the shelf unit 3 shown in FIG. 1) has a rectangular base cross-section which extends in the longitudinal direction L and transverse direction Q. The top of the shelf 5 forms a footprint 50 for storing stored goods 2. For simplicity, stored goods 2 is always shown in the present disclosure as a cube-shaped box. It is, however, clear that in principle any storage product which can differ from a cube in terms of its size, shape etc. can be stored with the modular storage rack system 1 or transported to the rail vehicles 100.

Below the footprint 50 of the shelf 5 includes a plurality (here six, for example) in the transverse direction adjacent, in the longitudinal direction L parallel to each other extending channels 71. Each channel 71 forms a hollow profile rail in which a rail vehicle 100 and load pickup vehicle can be added. Hollow profile rails are shown in the illustrated preferred embodiments by way of example as longitudinal channels 71 with a rectangular cross-section. Other hollow profile rail forms are conceivable.

In the preferred embodiment shown in FIG. 2, the longitudinal channels 71 are complementary to one another. They have a clear width w, which extends between two adjacent cross-sectionally T-shaped struts 73. The left or right outermost strut is L-shaped in cross section. The L- or T-shape of the struts 73 follows from the fact that the struts 73 are provided at its upper end with one or two projections 75, wherein the projections 75, starting from the extending in the vertical direction V struts 73 in the direction of Center of the adjacent longitudinal channel 71 extend. Compared to struts (not shown) without projections, the footprint 50 for stored goods 2 is markedly increased in the struts 73 and protrusions 75 shown here, so that advantageously even small storage goods can be received on the shelf 5 and thus almost the entire width of a shelf can be interspersed in the transverse direction Q with hollow profile rail for receiving rail vehicles 100. The rail vehicles 100 will be discussed in detail below, in particular with reference to FIGS. 3, 3b and 4.

The longitudinal channels 71 of the shelves 5 extend in the longitudinal direction L continuously open from the front shelf bottom side 51 to the rear shelf bottom side 52. The right and left shelf bottom side 53, 54 are in the illustrated in Figure 2 preferred embodiment of shelves 5 by closed, in the longitudinal direction L continuous struts 73 formed. The underside of the shelf 5 is formed as in the transverse direction Q and in the longitudinal direction L flat bottom plate on which drive the vehicle 100 described in more detail below. The longitudinal channels 71 are completely provided along their entire longitudinal extent with a through-opening 77 through which a arranged in a hollow profile rail 71 rail vehicle 100 for lifting and / or dropping on the stored material 2 above the footprint 50 can access. The width of the passage openings 77 in the transverse direction Q is smaller than the inside width w of the longitudinal channels 71.

As an alternative to the compartment floor 5 shown in FIG. 2, which is equipped exclusively with a longitudinal channel structure 7 extending in the longitudinal direction L, it is conceivable to provide a compartment floor 5 with a second channel structure or transverse channel structure (not shown in more detail), comprising the first channel structure 7 crosses. A second channel structure could, for example, extend completely from the left-hand compartment bottom side 53 to the right-hand compartment bottom side 54. The number of channels of a first channel structure and a second channel structure of a shelf may be different or equal. Preferably, the cross-sectional shapes of the longitudinal channels 71 extending in the longitudinal direction L in such a compartmentalized structure are equal to the cross-sectional shape of transversely extending Q transverse channels of a transverse channel structure or a second channel structure (not shown in detail). It is clear that the same applies to transverse channels as to longitudinal channels (taking into account the different orientation).

FIGS. 3a and 3b depict a group 102 in the transverse direction Q of rail vehicles 100 arranged next to one another. For the sake of simplicity, these rail vehicles 100 are shown in FIGS. 3a, 3b (and 4) without hollow profile rails receiving them. The schematically illustrated rail vehicles 100 have an elongated shape, that is, their length 1 in the direction of their direction of travel is greater, preferably more than twice as large as their width b and / or height h.

The rail vehicles 100 comprise a frame in which a traction drive technology is housed, each of the rail vehicle 100 has two drive and / or suspension means 103. In order to move the rail vehicle, at least one drive means 103 is preferably equipped with a drive motor. In the vertical direction V above the travel drive technology, the rail vehicle 100 has an elongated support surface 104, with which the rail vehicle 100 can receive stored goods 2. The height h of the rail vehicle is adjustable by means of a lifting device, so that in a hollow profile rail or a channel 71 on the rail vehicle in a lowered state can take a first, small height, which is less than the distance of the channel or rail bottom to the Footprint 50. Further, a rail vehicle can assume a lifting state in which the height h of the rail vehicle 100 by means of the lifting device (not shown) is increased to a height which is greater than the distance from the footprint 50 to the rail or channel bottom on which the rail vehicle 100 rises.

Preferably, the lifting device comprises a lifting unit, not shown. The lifting device is preferably designed to move the support surface 104 by at least 10 mm and / or less than 100 mm in the vertical direction V, preferably by 25 mm to 50 mm, in particular approximately 30 mm to 40 mm. The lifting device is preferably capable of lifting a load at a weight of more than 10 kg, more than 50 kg, more than 100 kg or even more than 500 kg. For lifting particularly large loads, groups 102 of adjacent rail vehicles 100 can be used. A group 102 includes at least two rail vehicles 100, but may also include more, such as three, four, five or six rail vehicles 100.

The rail vehicles 100 of a group 102 are coupled with each other according to signal transmission in such a way that they are capable of carrying out synchronous movements. For example, a central controller may collectively drive an entire group 102 of rail vehicles 100. It is also conceivable that a rail vehicle 100 of a group 102 of rail vehicles 100 acts as a master unit and communicates directly with the remaining rail vehicles 100 of the group 102 to cause them to perform synchronous movements. Other communication architectures are conceivable. The synchronous movement of grouped rail vehicles 100 may comprise a joint lifting movement for lifting a stored product 2 and / or the joint movement of a stored product 2 in the longitudinal direction L by means of a plurality of rail vehicles 100.

In the rail vehicles 100 shown here by way of example, the support surface 104 is formed as a conveying device, more precisely as a conveyor belt 105. The conveyor belt 105 can rotate in the longitudinal direction L of the rail vehicle 100. The width t of the conveyor is smaller, preferably about half as large as the width b of the slide 100. Since the conveyor has a smaller width t than the frame base 106 of the rail vehicle 100, the support surface 104 can access with the conveyor or the conveyor belt 105 through the passage opening 77 of a channel 71 on an item 2, wherein the passage opening 77 is smaller The width b of the frame base 106 may be substantially the same as the inside width w of the channel 71, which forms the hollow profile rail for the rail vehicle 100. Thus, the clear width w of the channel 71 can be fully utilized to provide the largest possible space for the rail vehicle 100 to accommodate its components, such as motor (s), battery (s), drive technology and lifting device. It can also be advantageous to provide a frame base 106 widened in relation to the through-opening 77 provided for the support surface 104, as a tilt-protection and / or an improved translational guidance for the rail vehicle 100.

Preferably, the cross section of the rail vehicle 100 may be formed in the form of, for example, an inverted "T" in order to fully utilize the available cavity within the hollow profile rail in the raised state of the rail vehicle as far as possible.

FIG. 4 shows two sets 101 of rail vehicles 100 arranged one behind the other in the longitudinal direction L, which form a modular conveying device for transporting stored goods 2. Between the rail vehicles 100 arranged one behind the other in the longitudinal direction L, a distance a can be provided which measures preferably a few millimeters or a few centimeters. The distance a may be formed with regard to the stored goods 2 to be conveyed. With known dimensions of a storage product 2, the distance may be dimensioned smaller, for example, so that it is less than half the length of the stored material 2 in the longitudinal direction L, so that a drop of stored goods 2 can be avoided. A large distance a may be preferred, for example, to bridge over long distances with as few rail vehicles 100 as possible. For a quick and / or safe conveyance, the distance a may be selected to be particularly small, but sufficiently large to prevent a collision of conveyors or conveyor belts 105 in the longitudinal direction L of rail vehicles 100 arranged behind one another.

A family of rail vehicles 100, like a group 102 of rail vehicles 100, can be coupled to one another in signal transmission. several Rakes 101 of rail vehicles 100 can be grouped together.

Figures 5a and 5b show a second embodiment of a modular storage rack system 1 according to a schematic representation in which the individual shelf units 3 are not highlighted in detail for ease of reading the representation. In the embodiments according to FIGS. 5a and 5b, the modular storage rack system 1 comprises three rows of shelves 104 arranged side by side in the transverse direction Q, at the front end of which a transfer robot 90 is arranged to remove stored goods 2 at the end face of the modular storage rack system 1 or leave. For this purpose, the transfer robot 90 has a transfer platform 95. The transfer platform 95 may preferably be formed corresponding to a shelf 5 or at least compatible with a shelf 5. The transfer platform 95 includes a plurality of hollow rails for receiving rail vehicles 100 or other load handling vehicles or devices to permit transfer of stored material 2 between the transfer robot 90 and the modular storage rack system unit. The transfer robot 90 can have a device for moving the transfer platform 95 in the vertical direction V, so that the transfer platform 95 can be brought to the vertical height of the different levels of the front shelf unit 3 of the storage rack system 1.

The modular storage rack system shown as an example in FIGS. 5a and 5b has three floors. It is quite conceivable that different longitudinal rows 104 are designed with different floor configurations. For example, the left two longitudinal rows 104 could each have three floors as shown and the third, right row of shelves could have a different number, for example two or five, floors.

With the carriage 93, the transfer robot 90 is movable in the transverse direction Q in the lane 97 along the end face of the modular storage rack system 1 from a rack unit to the next rack unit or from a rack row 104 to the next rack row 104. In the modular storage rack system 1 according to FIGS. 5a and 5b (and 6), the shelves 5 of the illustrated rack units 3 are each provided with two longitudinal channels 71 for forming hollow profiled rails.

FIG. 5 a shows how stored product 2 is lifted by the transfer platform 95 of the transfer robot 90 with the aid of two rail vehicles 100. The group of two rail vehicles 100 can enter from the transfer platform 95 into the shelves on the top floor of the shelving system 1 in order to drive the stored goods 2 to the storage position shown in FIG. 5b in the longitudinal direction L on the row of shelves 104. There, the rail vehicles 100 can store the stored goods 2. The rail vehicles can drive in the lowered state back to the beginning of the shelf row 104 or in the transfer platform 95.

FIG. 6 shows a four-storey modular storage rack system 1, in which a plurality of rack units 3, which are not shown in detail, can be arranged one above the other in the vertical direction V. The numerous legs of the shelf units 3 of the modular storage rack system 1 are not shown in detail for clarity of illustration. The shelf units are stacked on three floors. Each shelf unit 3 carries three floors of shelves 5. On the front side of the storage system 1, three superimposed lanes 97 are provided in the vertical direction V, which can carry the wagon 93 of a transfer robot 90. The shelf units are grouped into six longitudinal rows 104 arranged directly next to one another.

In the modular storage rack system 1 according to FIG. 6, a group of paired rail vehicles 100 are arranged in two levels of the rack system. Proceeding from the reference position of the transfer robot 90, the upper rail vehicle group 101 conveys stored goods 2 backwards, in the longitudinal direction L away from the transfer robot 90. The lower rail vehicle group 101 conveys stored goods 2 forward, in the direction of the transfer platform 95 of the transfer robot 90 respective conveying direction of the shares 101 is indicated by arrows. If larger quantities of stored goods 2 are to be moved on a floor, the use of a rail 101 of rail vehicles 100 can offer speed advantages compared to transport by means of a non-group of rail vehicles (as shown in FIGS. 5a and 5b). This may be advantageous, for example, if a container arranged relatively far to the rear in a rack is to be picked for picking. contains, but first more forward in the same floor standing container must be removed from the way, for example, to another floor to access the container with the desired shipping.

The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
