As shown in the figures, the storage system with movably arranged storage parts 1 executed. Here is each of the memory parts 1 each driven by chain drives on both sides. The storage system is designed in particular similar to a paternoster.

The chain drives are operated synchronously and are by means of chain links of the chains 10 the chain drive arranged bolts with the respective chain 10 connected. The bolts are not aligned coaxially, causing a tilting of the storage parts 1 is preventable.

The respective chain 10 is from a particular engine 11 driven, the engines 11 be operated synchronously. Preferably, electric motors are used for this purpose.

By means of the storage parts 1 each different transport goods are receivable, in particular a first cargo 2 , in particular box of the first kind, a second item to be transported 3 , in particular box of the second kind, and / or a third item to be transported 4 , in particular box of the third kind.

The at the memory part 1 transported goods ( 2 . 3 . 4 ) are in rows on the storage section, depending on size and requirement 1 storable around storable.

For storage or retrieval a likewise driven by the chain drive gripper tool is moved to a corresponding position, so that a gripping bar 5 of the gripping tool a transported goods ( 2 . 3 . 4 ) can record or deliver.

The gripping tool and the storage parts 1 are therefore movable on a closed path. For storage or retrieval, the chain drives are stopped.

The gripper bar 5 each has a Transportgutaufnahme 24 on, with which the transported goods ( 2 . 3 . 4 ) are positively accommodated.

For this purpose, the transported goods ( 2 . 3 . 4 ) respective formations on. At the first cargo 2 this shape is designed as a collar edge, especially as a border. The gripper bar 5 is herself or with her transport goods intake 24 Positionable under the collar edge. Thereafter, by moving the chain drives the cargo 2 raised. During storage, the procedure is reversed.

In the second cargo 3 is a recess, in particular in the wall of the cargo 3 arranged blind hole or through hole, shaped, so that the side of the gripper bar 5 arranged Transportgutaufnahme in this recess is at least partially retractable. For retraction, the gripper bar is moved transversely to the direction of the chain drive by the transverse movement is carried out by means of an electric motor-driven spindle drive. After retracting the transport goods intake 24 in the recess of the cargo is by moving the chain drive the cargo 2 raised. During storage, the procedure is reversed.

For storage, the gripper tool must be brought to such a position of the chain drives that the linearly movable gripper bar 5 with her Transortgutaufnahme 24 to the respective transport item ( 2 . 3 . 4 ) is movable towards.

The linear driving of the gripper bar 5 takes place by means of a linear drive. Here, the linear movement is aligned transversely to the conveying direction of the chain drive. However, the transverse direction is perpendicular to the conveying direction of said spindle drive and is in particular directed such that on the provided memory part 1 stored transport goods ( 2 . 3 . 4 ) is receivable.

The linear drive is designed in such a way that that of the gripper bar 5 picked up cargo ( 2 . 3 . 4 ) can be positioned on either side of the gripping tool either on a storage floor of the storage system or alternatively for delivery to a arranged outside of the storage system shelf or to a conveying device, such as roller conveyor unit or assembly line. Preferably, the cargo is stored in a shelf of a mounting island of a manufacturing plant or taken from there.

The linear drive has a cable drive, which on a base plate 32 makes guided gripping bar displaceable. The cable drive is provided on the base plate and has a rope 30 on, that of a drive wheel 31 is driven, which is driven by an electric motor.

Every grab bar 5 is driven by a spindle drive, wherein the respective spindle drive an electric motor 20 which has a spindle 23 which cooperates with a spindle nut 22 which is in a spindle nut receptacle 21 is included. The spindle nut receptacle is along a guide rod 6 traversable. So if the spindle 23 from the electric motor 20 the gripping tool is set in rotary motion, the spindle nut receptacle moves 21 corresponding. With the spindle nut receptacle is the gripper bar 5 movable together with its cable drive.

In this way, the two gripping bars 5 movable relative to each other and a transported goods ( 2 . 3 . 4 ) can be clamped, so non-positively absorbable.

Thus, therefore, the respectively provided cargo ( 2 . 3 . 4 ) non-positively and / or positively received by the gripping tool.

The gripping tool is also a laser scanner 7 arranged, which, in particular in a respective, to the memory part 1 parallel aligned plane that makes the removal of objects determinable. Thus, the removal of stored in a shelf next to each other transport goods ( 2 . 3 . 4 ) and their width as well as the between the adjacent transport goods ( 2 . 3 . 4 ) available clear width determinable.

The guide rods 6 of the gripping tool are aligned in the transverse direction of the conveying direction of the chain conveyor. Thus, the gripping bars are movable in this transverse direction and in particular the relative distance between the two gripping bars 5 mutually reducible.

Perpendicular and in another transverse direction to this are the gripper bars 5 of the gripper tool in each case by the respective cable drive can be moved, ie in particular in the storage system in or out.

In this way, so after reaching a suitable relative positioning between the storage floor 1 and gripping tool the picking or delivering a cargo ( 2 . 3 . 4 ) executable.

Preferably, the storage system is mounted on a vehicle or rack movable on a floor. In particular, an automatically guided vehicle (AGV) or a driverless transport system (FTS) can be provided as a vehicle. Thus, then the storage system is loadable at a first position on the ground and dischargeable at another position. In particular, in a production plant, a shelf of a mounting island can be filled with transport goods ( 2 . 3 . 4 ), which were previously recorded in a separate warehouse warehouse.

In the invention, therefore, a paternoster storage is used as a storage system and the gripping tool as a load change device or load-carrying means. The integration of the gripping tool in the storage system offers a high transport goods capacity in a small space, as well as the ability to carry out bilateral load changes. Due to the special design, a flexible use of each storage shelf is also possible. Each storage floor can be loaded with a large cargo or a large number of small goods - depending on transport dimensions. In this case, the access to each transported goods in the storage is executable at any time.

The overall structure of the invention is based on the principle of a paternoster memory. Due to the two diagonally arranged chain drives of the paternoster, the storage parts, which are each suspended on the chain by means of two bolts, and the equally connected gripping tool can follow a track which is similar to the track of the chain with respect to the bore of the fastening bolt. By running along the gripping tool on the paternoster chains, the stroke of the load change device is integrated in the paternoster drive and thus no additional drive for the stroke is necessary. As a paternoster drive, the two motor gear units are each arranged on the lower sprocket of the respective chain drive.

The attachment of the motor gear units is in each case via an engine mount of the linkage, which is bolted to the profile frame of the linkage. This motor mount and the sprocket bearing plate allow adjustment of the chain tension by moving it on the profile frame.

In addition, each of the upper sprocket of the two chain drives is suspended rotatably mounted with the sprocket bearing plate. The guidance of the tensioned chains by means of four, consisting of two slides chain guides, which are attached via chain guide brackets on the profile frame of the linkage.

On the gripping tool are the gripper bars 5 So, two separately movable telescopic units, which allow the horizontal axis movement of the goods to be transported from the transfer station to its own internal memory part.

To the gripping tool and thus also the two telescoping units with energy supply, two contact lines are attached to the profile frame via two conductor rail holders. Alternatively, however, an inductive energy transfer or the energy transfer via an endlessly circulating drag chain would be realized.

The storage system can be connected to a sufficiently accurate and also narrow driverless transport vehicle (AGV) for operating rack aisles of a warehouse. Here, the two-sided feasible load change, the operation of both shelf pages without turning the AGVs possible. Due to the high design, a load change between, for example, 300 and 1800 mm transfer height take place.

The gripping tool is, apart from the hub, the actual element for load change. The realized here separate connection of the two telescoping units allows the individual loading of the storage floors, ie memory parts. The gripping tool is connected by two bolts through a hole in both guide rod carriers to the Paternoster chain. In addition, the guide rod carriers are used to connect all other components. So are the two guide rods attached to it. On them run the two telescope units by means of compact ball bushings.

At the guide rod carriers, the two motors for driving the spindle drives, so the respective ball screw are also mounted on suitable production parts. These ballscrew spindles are mounted in the two bearing blocks by means of two ball bearings. In these bearing blocks is also ever a clutch for connecting ball screw and motor shaft. When one of the two ballscrews is driven, the corresponding telescoping unit connected via a ball screw nut moves linearly along the ball screw or guide rods. By carrying out this axle with two ballscrew spindles, one for each telescoping unit, the method of the telescoping units is made possible independently of each other. The motors are each controlled by a motor controller. The drag chains serve to guide the power and signal supply lines for the telescoping units. As a power and signal cable, a four-core cable can be used here (2 x power supply 24 V DC and 2 × signal CAN-high / CAN-low).

As explained in the description of the overall structure, two sliding lines are attached to power the gripping tool. The use of inductive energy transfer is alternatively possible. Depending on the ultimate energy transfer, either a transmitter head or sliding contacts are required. If necessary, energy storage can be used to bridge any necessary contact interruption of the sliding contacts. Space for these components was designed with an electronic circuit, which also has a CAN-to-WLAN converter or CAN wireless modules for wireless signal transmission. If required, taking into account other disturbing contours of the construction, further installation space is available for other electrical circuit units.

In order to determine whether a transfer point is free or occupied, for detecting the transported goods, for determining the free distances next to the transported goods and for detecting the transport goods position, the laser scanner is fastened by means of a profile rail holder 7 ,

The telescoping unit is the element that performs the horizontal load change from the transfer station to the internal storage floor. Technically implemented by the Seilzugmechanismusses. By a driven wire rope drum, the wire rope is on the one hand unwound from the drum and on the other hand wound up on the wire drum. Thus, the wire rope of one side shortens while it lengthens on the other. This allows two-sided telescoping. The cable rope, which can be wound up or unwound from the cable drum, is deflected on each side via three pulley elements and finally fastened via a cable tensioning device to the last element of the telescopic guide. The telescopic guide takes over the Transportgutaufnahme 24 the load, ie the cargo ( 2 . 3 . 4 ) on. The transport goods reception 24 is designed so that it can accommodate goods with an accessible edge. In addition, the inclusion of goods is possible, which have the same grip variants, such as EuroBoxes. By the lateral attachment of a Gummireibfläche is also the gripping light cargo ( 2 . 3 . 4 ), such as packaging in the form of cardboard boxes, possible, provided that transmitted by the gripping tool lateral contact force generates sufficient frictional engagement for lifting. The cable tensioning device allows for the release of a screw-nut connection, to which the wire rope is attached, the displacement of the nut in a groove and thus the tensioning of the wire rope. Of the pulley elements are two pieces attached to the central element of the telescopic guide and another two on a spacer element. This spacer element is in turn connected to the carrier plate and thus also to the fixed element of the telescopic guide. At the two upper corners of the support plate two ball bushing holders are attached on both sides, in each of which a compact ball bush is pressed. The compact ball bushings hold in a hole without additional fixation.

Above - in the middle of the carrier plate - the carrier carriage is fixed, in which the ball screw nut sits. In a second hole in the carrier carriage runs with play the ball screw of the other telescoping unit without being connected. The carrier slide is milled out and thus offers the bearing block of the spindle bearing the opportunity to retract it.

The wire rope drum of the telescopic unit is driven by means of a motor gear unit, which in turn is attached to the carrier plate with a motor mount. The motor controller for controlling this drive is the same as the motor controller already used in the spindle drive motors.

In the manufacturing plant according to the invention, a shelf storage is arranged, this being divided into shelves. Each shelf has shelves, each shelf has one or more storage bins.

In the manufacturing plant assembly islands are arranged, each of the assembly islands also has a shelf. For the production of products, goods are taken from the shelf of the assembly island. As soon as a demand for transport goods arises, the vehicle according to the invention, which has the storage system, picks up transport goods in the rack storage and transports them to the shelf of the assembly island.

For this purpose, the information is transmitted to the vehicle, which transported goods must be brought from the shelf storage to the assembly island.

Although the vehicle is also informed on which shelf is to be picked up cargo, but the exact storage space is not communicated. Likewise, as the delivery destination, the shelf of the assembly island or the assembly island is transmitted to the vehicle, but the exact storage space is not communicated.

Thus, the vehicle drives to the shelf warehouse and searches by means of the laser scanner the corresponding shelf for the transported cargo ( 2 . 3 . 4 ). For this purpose, it is determined by means of the laser scanner whether in the sensitive area of the laser scanner the searched barcode is recognizable. If not transported ( 2 . 3 . 4 ) can be found in the sensitive area of the sensor, the vehicle is moved further and thus examined a new area of the sensor. In this way, the sensitive area is gradually moved along a respective shelf and searched for the transported goods. After searching the first shelf, the search is continued in the next shelf and so on.

Alternatively, at each vehicle position, the chain drive is driven so that scanning in the vertical direction is performed first, ie, from bottom to top, and thereafter changes the vehicle position as described

After finding the transported goods ( 2 . 3 . 4 ), the vehicle and the chain drive is moved in such a way that the transported goods can be received by the gripping tool and transported to the assembly island. There, a free storage space is sought for storing the cargo, in turn, each storage space of each shelf is examined, if it is assigned to the barcode and if the storage space is free and large enough, so used for storage of the cargo.

As in 7 . 8th and 9 shown has the memory part 1 a plate 71 with perforated grid, which by means of screws 83 with a housing part 82 are connected. In the holes are bolts 80 introduced, which has a paragraph, so jumped course of the outer diameter.

Contrary to the force transmitted by the cables, spring elements press 184 bolts 18 in the insertion direction from the storage part 1 out. In this case, the spring elements are based 184 on a support section 183 of the memory part.

Thus, each spring element pushes a bolt 184 from the support section 183 path.

Bolts 184 are each from a rope ( 181 . 182 ) to the memory part 1 arranged retractable. The ropes ( 181 . 182 ) via a deflection section 186 to an actuator plate 187 guided. By pressing the actuator plate 187 against the spring force of a spring element 180 become the page ( 181 . 182 ) and thus the bolts to the storage part 1 pulled out, so from the respective chain link of the chain 10 pulled out. The on the same side of the memory part 1 arranged bolts 185 are integrally executable with each other, in particular as a bolt portions of a correspondingly shaped, along the side of the storage part 1 extending plastic injection molded part. Here is the first plastic injection molded part of the rope 181 and the plastic injection molded part associated with the opposite side of the rope 182 connected. In this way, both plastic injection molded parts are the storage part at the same time 1 Towable, so in the direction of the deflection 186 out.

In a further embodiment of the invention, the sprockets 11 the chain drives are on the linkage 9 the bearing system additionally feasible, in particular by means of a corresponding linear guide.

In a further embodiment of the invention, another drive, such as pneumatic drive, electromotive linear drive or hydraulic drive is used instead of the cable drive. Instead of the spindle drive, such a drive can also be used.
