Description

Picking vehicle for a storage system and storage system comprising at least one shelf and at least one picking vehicle

The present invention relates to a picking vehicle with a chassis and a body, which has a plurality of receptacles for items. It further relates to a storage system for objects, comprising at least one such picking vehicle and at least one shelf with a plurality of receptacles which serve to store objects and are accessible from an access front, along which an aisle extends, along which the picking vehicle can be moved is.

Picking vehicles and storage systems of the type specified above are used in a large number of different designs in various fields of application. A preferred field of application is the manufacturing industry, such as automobile manufacturing. In this application, the individual components and / or preassembled assemblies for the products (vehicles) to be manufactured are stored on the shelf, and only one specific type of components or assemblies per receptacle. The picking vehicle, which can be moved along the access front of the shelf, is loaded with the combination of components or assemblies specific to the product to be manufactured, which are taken from the correspondingly selected images of the shelf on the access front. The components and assemblies placed on the picking vehicle are then transported to the assembly station for the product to be manufactured.

Since considerable distances often have to be covered both within the warehouse and between the warehouse and the assembly stations, it is economically It is desirable to be able to collect and transport the product-specific components and assemblies of several products to be manufactured on one picking vehicle at a time. Generic order picking vehicles with several receptacles are used for this. However, there is a risk of incorrect loading by placing a part that has been correctly removed from the rack in a wrong receptacle. Such incorrect picking triggers considerable costs for the subsequent correction, the effort being particularly high if an incorrect component is initially installed and later has to be replaced by an appropriate one. Manufacturing errors due to incorrect picking must also be avoided from the point of view of loss of image.

In the light of the problems outlined above, the object of the present invention is to provide a picking vehicle of the type specified at the outset and a storage system comprising this, in which the risk of incorrect picking is reduced.

This object is achieved according to the present invention in that the receptacles of a generic picking vehicle are mounted such that they can be changed in position so that individual receptacles are successively accessible from a predetermined operating position, which can be arranged in particular on a front side of the body of the picking vehicle that has an operating handle. In particular, it can be provided that only one of the receptacles is accessible from the operating position. With such a picking vehicle, it is possible to pick up objects for different products to be manufactured on a single tour without the risk of incorrect assignment of the corresponding objects to the product in question in each case. In this way you can simultaneously - opposite Known picking vehicles with only one receptacle - save considerable distances and - compared to known picking vehicles with several receptacles - save costs for the later correction of incorrect picking.

When passing through the shelves, that of the receptacles in which the object to be removed next from the shelf is to be placed can be automatically brought into the position in which it is accessible from the specified operating position (e.g. via a corresponding opening). In this case, a motor drive is provided for changing the position of the receptacles; and the storage system, of which the corresponding order picking vehicle forms part, is also expediently equipped with a device for detecting the respective position of the order picking vehicle, the drive for changing the position of the receiving containers being controlled using the position data provided by the position detection device ,

Meanwhile, technically simpler picking vehicles without such an automatic selection of the receptacles or automatic change of the position of the receptacles, possibly even with a manual adjustment of the position of the receptacles, can be used appropriately.

According to a preferred development of the order-picking vehicle according to the invention, the individual receptacle containers are suspended in a gondola-like manner on one wheel or two wheels facing one another with an axis of rotation extending horizontally transversely to the direction of movement of the vehicle. According to a possible alternative to this, the receptacles are paternoster-like on two flexible endless lines which are each guided synchronously along a predetermined path. strands (such as link chains) hung. Such order picking vehicles prove to be particularly favorable for use in those storage facilities which are characterized by particularly narrow aisles and in which the predetermined operating position is therefore arranged on an end face of the order picking vehicle. These developments are outstandingly suitable for an automatic change in the position of the receptacle caused by a motor drive.

Another preferred development of the commissioning vehicle according to the invention is characterized in that the receptacles are guided in a drawer-like manner in horizontal guides of the body. In particular, several receptacles can be coupled one behind the other in the direction of displacement and cover devices can be provided, by means of which receptacles are covered, which can be moved beyond a loading position in which they are accessible in order to bring another receptacle into its loading position. This further training is ideally suited for a manual change in the position of the receptacles.

Regardless of the construction, the receptacles of the commissioning vehicle according to the invention are particularly preferably detachably suspended or attached. After they have been loaded as part of the order picking vehicle, they can be removed from the body of the order picking vehicle and remain at the production station, while the order picking vehicle, fitted with new receiving containers, is used again. This saves time and saves the multiple reloading associated with the risk of damage to the objects. The receptacles are preferably equipped with a conventional coding carrier (eg transponder, bar code label or the like) which enables their identification. This allows continuous monitoring Checking the receiving containers in the order picking vehicle in order to identify the receiving container to be loaded in each case and beyond their loading in the order picking vehicle. As an alternative or in addition, the receptacles on the vehicle for the detachably suspended receptacles preferably (also) each have such a coding carrier. In the case of additive coding carriers, this enables reliable control of the correct assignment of a specific receptacle to a specific vehicle-side receptacle.

According to a further preferred development, a reading device is arranged on the order picking vehicle and is connected to a data processing unit of the storage system, of which the order picking vehicle forms a part. This reading device can be used in particular to read identification codes (e.g. transponders) that are attached to the objects with which the order picking vehicle is to be loaded. This enables an immediate check to be made as to whether the objects with which the order picking vehicle is loaded are the correct ones.

With a view to further reducing the risk of incorrect picking, the storage system, of which an order-picking vehicle according to the invention forms part, preferably has an electronic data processing unit which has a data memory for selection data which define a selection of recordings of the shelf and one for optical identification controls the suitable high-light marking device of the recordings of a shelf as a function of the selection data. In this way, the risk that incorrect items are removed from the shelf is significantly reduced.

The luminous marking device for optically marking the individual receptacles on the shelf can be designed in accordance with a prior art known as such be that on the individual shots of the shelf in the area of the access front, suitable lights are provided, which are connected to the data processing unit of the storage system via a wiring, by means of which the person loading the picking vehicle is shown which shots of the shelf they are currently for manufacturing product has to take components or assemblies. In this case, according to a further development, the lights can be switched relative to the shelf as a function of the respective position of the order-picking vehicle, in that the control of the illuminated marking device processes position data that are provided by a position detection device that determines the position of the order-picking vehicle relative to the shelf.

However, the luminous marking device provided for the optical identification of the recordings of a shelf is particularly preferably not arranged on the shelf, but rather on the order picking vehicle according to the invention. With this further development, the flexibility is higher and the installation effort is less than with storage systems with a stationary marking device installed on the shelf. The corresponding storage system for items, comprising at least one order picking vehicle, at least one shelf with a plurality of receptacles, which serve to store items and are accessible from an access front, along which an aisle extends, along which the order picking vehicle can be moved The following features are particularly preferred: - A guiding device extends along the aisle, by means of which the picking vehicle is guided along a defined path that runs parallel to the access front of the shelf; - The storage system has a position detection device for determining position data which the position define the picking vehicle relative to the shelf on; - The electronic data processing unit includes a data memory for arrangement data, which define the spatial arrangement of the individual images of the shelf; - The luminous marking device is arranged on the order picking vehicle and comprises at least one luminous marking unit emitting a light beam, which is controlled by the data processing unit as a function of the position data and the arrangement data selected according to the selection data.

This storage system is characterized in particular by the fact that the or each order-picking vehicle has at least one luminous marking device, by means of which the selected images of the shelf from which objects can be removed are marked. For this purpose, the data processing device, by means of which the luminous marking device is controlled, takes into account, in addition to the selection data relating to the specific selection of recordings, on the one hand the position data which define the position of the picking vehicle in relation to the shelf and on the other hand arrangement data (i.e. coordinates in relation to a predetermined reference point) which defines the spatial position of the individual images of the shelf. It is therefore characteristic of this storage system that it does not have a highlighter device permanently installed on the shelf. This has a decisive impact on the manufacturing costs; because compared to the prior art, this storage system eliminates any effort associated with the installation of a large number of lights on the shelf, including the wiring of the highlighter. Another significant advantage of this storage system is increased flexibility when it comes to dividing the shelves; because as a result of the elimination of the luminaires assigned to the individual images and the corresponding sales The recordings can be freely defined on the shelf without restriction.

According to a preferred development, the luminous marking device comprises a light beam straightening device, by means of which the height and / or the side of the light beam emitted by the luminous marking unit can be changed, based on the chassis of the order picking vehicle. By changing the direction of the light beam to the side, from a single position of the order picking vehicle, several recordings of the shelf arranged side by side can be optically marked one after the other; this saves the person loading the picking vehicle from having to move and reposition it all too often by only small distances along the path. And by changing the direction of the light beam according to the height, the number of highlighter units to be provided on the order picking vehicle can be kept low. Against this background, the light beam straightening device is preferably designed to change the direction of the light beam emitted by the luminous marking unit both in height and in side. However, this is not mandatory. In special applications, it can make sense to restrict the light beam straightening device to a change in the direction of the light beam emitted by the luminous marking unit only in height or only to the side, or to dispense with a light beam straightening device entirely.

If the luminous marking device according to the above statements comprises a light beam directing device, this can be designed in particular to change the spatial position of the luminous marking unit. In order to direct the light beam emitted by the luminous marking unit onto the respectively selected image, the luminous marking unit as a whole is used in this development of the invention. moves, in particular pivoted and / or move along a guide. Such a design of the luminous marking device is by no means mandatory; rather, the light beam straightening device can also comprise, for example, an arlenk unit for variably deflecting the light beam emitted by the luminous marking unit, which itself cannot be moved.

In particular, if the luminous marking device does not comprise a light beam straightening device in the sense described above, the luminous marking device will regularly have a plurality of luminous marking units arranged essentially one above the other, the individual luminous marking units being assigned to different levels of the shelf.

According to another preferred development of the storage system, it is provided that the order-picking vehicle has two light-marking devices, the light-marking units of which emit light beams to different sides of the path of the order-picking vehicle. This is particularly economical if two shelves face each other in such a way that their access fronts point essentially parallel to one another to the same aisle; because on; in this way, the picking vehicle can be loaded with objects from the two adjacent shelves during a single pass through the corresponding aisle.

To determine the position data, a position data transmitter can extend along the path for the order-picking vehicle, the order-picking vehicle being equipped with a position data sensor that interacts with the position data transmitter. However, less effort is required if there is a marker at the entrance of each aisle which, when passing the picking vehicle, resets an odometer on the vehicle side to zero, the current position of the picking vehicle relative to the shelf in the respective aisle being determined by evaluating the data provided by the odometer. Yet other preferred embodiments of the position detection device comprise an (one-dimensionally measuring) optical distance meter or an (two-dimensionally measuring) optical distance scanner, the measuring beam or measuring range of which extends parallel to the access front of the shelf and which determines the distance to a position mark protruding into its measuring region , whereby either the range finder or distance scanner can be fixed (for example on the shelf) and the position mark can be arranged on the order picking vehicle, or vice versa. A particular advantage of these further developments using an optical distance scanner is that the distance scanner can be used for monitoring the access front of the shelf in addition to determining the position data in the sense of EP 994761 B1. Under operating conditions characterized by a relatively large shelf area and a rather small number of order picking vehicles, the use of such a combined storage system with integrated monitoring is particularly pronounced if the optical distance scanner is arranged on the order picking vehicle. In this case, the storage system according to the invention manages with a significantly reduced number of distance scanners compared to a fixed mounting of the distance scanners on the shelves.

According to yet another preferred development, the storage system according to the invention has a positioning aid display device connected to the electronic data processing device, on which positioning aid data is displayed. The positioning aid data is dependent on the position data that are determined by the position detection device and on target position data that are used to mark the respectively selected Define suitable recordings of the shelf suitable positions of the picking vehicle and are stored in a corresponding target position data memory of the data processing device, determined by comparing the relevant data. Using the positioning aid data, the picking vehicle can be brought into the optimal position with little effort. It is particularly advantageous if the positioning aid display device comprises a display arranged on the order picking vehicle.

According to yet another preferred development, the storage system according to the invention is characterized in that an identification unit connected to the electronic data processing unit is provided with a first identification means assigned to the track and a second identification means assigned to the picking vehicle and interacting with the first identification means. This allows monitoring whether the respective picking vehicle is entering the correct aisle in which items are to be picked up; if this is not the case, an acoustic and / or visual alarm can be triggered. The identification means assigned to the path can form a unit with the marker described above, which is preferably arranged at the entrance of each path.

A data communication of the components built on the picking vehicle with the stationary data processing unit of the storage system, which is required in various configurations of the present invention, can take place using conventional wireless transmission standards. Data communication, which is particularly reliable even in an environment with a high potential for disruption, takes place, however, via two grinding rails which extend along the path of the order picking vehicle and associated customers arranged on the order picking vehicle. With regard to the reliability of data communication at low cost The use of a four-pole standard grinding rail unit is particularly favorable, two grinding rails being connected in parallel.

The above-described illuminated marking device arranged on the order picking vehicle can clearly be used with great benefit also in connection with storage systems whose order picking vehicles correspond to the state of the art. Order-picking vehicles without a receptacle that can be changed in position can also advantageously have a vehicle-side highlighter device in the sense described above. For this reason, the applicant reserves the right to claim isolated protection for the equipment of order picking vehicles with a vehicle-mounted highlighter and other such order picking vehicles, regardless of the design of the order picking vehicles, in particular by way of a divisional application.

For the sake of clarity only, it is pointed out that the present invention is in no way restricted to those storage systems in which objects are removed from the shelves on the respective access front. Rather, the present invention relates in the same way to storage systems in which the shelves are loaded from the respective access front. Also for the sake of clarity, it is pointed out that the specific arrangement of the data processing unit is irrelevant to the present invention. The data processing unit will often be part of a central data processing system which controls the entire material logistics, the components attached to the picking vehicles communicating in the usual way with the central, fixed data processing unit; however, the individual picking vehicles can because be equipped with the necessary data processing capacity. Mixed systems are also conceivable in this respect.

In the following the present invention is illustrated in the

10 is a perspective view of a further order picking vehicle according to the present invention.

The storage device illustrated in FIGS. 1 and 2 comprises two shelves 1 with a plurality of receptacles 2 arranged one above the other and next to one another for objects to be stored. Aisle 3 runs between the two shelves 1. The two shelves 1 are set up so that they point to aisle 3 with their respective access front 4. Along the aisle 3 is a picking vehicle 5, which has a chassis 6 and a body 7 with a plurality of receiving containers. nissen 8 for objects, movable. To this extent, the storage system according to FIGS. 1 and 2 corresponds to the well-known prior art, so that further explanations are not required.

A guide device 9 extends along the aisle 3 in the form of a guide rail 10 arranged at the bottom on the access front 4 of the shelves 1. Claws 11, which are arranged on the order-picking vehicle 5, engage in that guide rail 10. The picking vehicle 5 is guided along the aisle 3 by means of the guide device 9 along a defined path B, which extends parallel to the access fronts of the shelves 1.

Two illuminated marking devices 12 are arranged on the order-picking vehicle 5 in the region of the rear side edges. Each luminous marking device 12 comprises six luminous marking units 14 mounted one above the other on a support 13, each corresponding to the level of the receptacles 2 of the shelves 1. The luminous marking units 14 are - in a manner known per se - suitable for emitting light rays 15, the light rays each reflecting the Access opening of a receptacle 2 are directed to mark this for the person 16 loading the picking vehicle. The two luminous marking units 12 are provided for emitting light beams 15 to different sides of the path of the picking vehicle 5.

The luminous marking units 14 are controlled by a data processing unit (not shown), taking into account three data groups, namely selection data which define a specific selection of receptacles 2 of the shelves 1, arrangement data which determine the spatial arrangement (e.g. coordinates) of the individual receptacles 2 of the shelves 1, and position data, which the respective position of the picking vehicle 5 relative to the Define shelves 1. By evaluating this data, of which the selection data and the arrangement data are stored in corresponding memories of the data processing unit, the luminous marking units 14 use a light beam 15 to mark those receptacles 2 from which the operator can remove 16 objects and in a, if necessary, a specific one Has to store receptacles 8 of the picking vehicle 5.

To determine the current position data of the picking vehicle 5, a position data transmitter 17 in the form of a marker 18 is arranged at the entrance of each aisle 3, which is detected contactlessly by a position data sensor 19 on the vehicle as it passes the picking vehicle 5. In this sense, if the position data sensor 19 detects the marker 18, an odometer on the vehicle is set to zero. The position data defining the position of the order-picking vehicle 5 relative to the shelf 1 are determined from the distance covered in the aisle 3 in question relative to the marker and recorded by the vehicle's odometer.

With the marker 18, a first identification means forms a structural unit. Correspondingly, a second identification means forms a structural unit with the position data sensor 19. The two identification means together form an identification unit which is connected to the

Data processing unit is connected and by means of which the entry of a specific picking vehicle 5 into a specific aisle 3 can be monitored.

A positioning aid display device, which comprises a display 20 arranged on the order-picking vehicle 5, is connected to the electronic data processing device. Positioning aid data is shown on the display 20, which the operator 16 at the optimal position. Support the picking vehicle 5. The positioning aid data are determined by comparing the position data explained above with target position data which define the positions of the picking vehicle suitable for marking the respectively selected receptacles 2 of the shelf 1 and are stored in a corresponding position target data memory of the data processing device.

The shelves 1 are equipped with access monitoring in accordance with EP 994761 B1. For this purpose, an optical distance scanner 21 connected to the data processing unit is arranged at the top of the access front 4 of the shelves 1. As an alternative to the above-described position detection by means of the marker 18, the position data sensor 19 and the distance counter, the position data can also be detected by evaluating the position of the position mark 22 attached to the order picking vehicle 5 and protruding into the measuring range of the distance scanner 21 ,

According to FIGS. 3 to 6, the order picking vehicle 5 - shown without a luminous marking device and without a display - comprises a total of six receptacles 8 arranged in three levels one above the other in the form of plastic boxes. The receptacles are each guided in pairs in the structure 7 of the picking trolley in a drawer-like manner in horizontal guides 41. For this purpose, three guide rails 43 are attached to each of the two side frames 42 of the order-picking vehicle, a push frame 44 being slidably guided in each of two opposite guide rails, onto which the two assigned receptacles are removably placed. An operating handle 40 comprising two handles 45 is arranged on one of the two end faces of the order-picking vehicle 5, by which the operating position is defined. In the transport mode shown in FIG. 3, none of the six receptacles 8 is accessible. Rather, the two upper receptacles are covered by a cover plate 46; and the two middle and the two lower receptacles 8 are each covered by the two immediately above receptacles.

FIG. 4 shows the order picking vehicle according to FIG. 3 in a first loading mode, in which the receptacle 8a, which is closest to the operating handle 40 and is rearward in relation to the main direction of travel F, is accessible in the middle level. For this purpose, the associated middle push frame 44a is partially pulled out, namely by the depth of the receptacle 8, from the transport position in the direction of the operating handle into a first loading position. The five other receptacles are still not accessible.

In order to make the receptacle 8b facing away in relation to the main direction of travel F and accessible from the operating handle 40 accessible in the middle plane for loading, the middle push frame 44a is pulled out again by one division in the direction of the operating handle. In this case, a roller blind-like cover device 47 arranged on the push frame 44a is activated by fixing the free end 48 of the cover 50 initially wound on a core 49 via stops 51 to the two side frames 42 and in this way being unwound when the push frame is pulled out further, and that covers rear receptacle 8a. When the push frame is pushed into the body of the picking vehicle, the cover 50 winds up again. The same applies correspondingly to the roller-type covering devices 47 on the two further push frames 44. Suitable locking devices ensure that only one of the push frames can be pulled out of the transport position

Each receptacle is equipped with a coding carrier 37 in the form of a transponder. On the one hand, continuous detection of whether the correct receiving container 8 is in its loading position is made possible by detecting the respective transponder by means of the reading device 52 arranged on the body of the picking vehicle; Furthermore, each receptacle can also be tracked after it has been removed from the picking vehicle 5, i.e. in particular, the correct assignment of the receptacle in question to a specific assembly station can also be monitored. The vehicle-side reading device 52 can also be designed to read coding carriers which are attached to the individual objects to be stored in the respective receptacle 8.

To remove the boxes from the order-picking vehicle 5, the push frames 44, as illustrated in FIG. 6, can be pulled forward out of the body 7 of the order-picking vehicle in the direction of travel F.

As far as the second embodiment of a storage system according to the invention illustrated in FIGS. 7 and 8 and the order picking vehicle 5 'used here according to FIG. 9 are concerned, their basic design features result directly from the above explanations of FIGS. 1 and 2. To avoid repetition, reference is made to the above statements and only the deviations are discussed below.

The picking vehicle 5 'is guided here on two guide devices 9', each of which has a guide rail 10 'arranged at the top of the access front 4 of the shelves 1. include. Claws 11 'engage in the guide rails 10' and are attached to a crossmember 23 which extends across the top of the order-picking vehicle 5 '.

At the end of the crossbeam 23, two optical distance scanners 24 are essentially mounted, the measuring range 25 of which extends parallel to the access front 4 of a shelf 1. Using one of the distance scanners 24, the position of the order-picking vehicle 5 'relative to the shelves 1 is determined, for which purpose a position marker 26 is embedded in the measuring area 25 of the distance scanner in question in the floor of the aisle. In addition, the two distance scanners 24 are used to monitor access to the receptacles 2 of the shelf 1, in particular in the sense of checking whether the selected receptions, each marked by the luminous marking devices 12 ', are being accessed.

The order picking vehicle 5 'used in the embodiment according to FIGS. 7 to 9, like the order picking vehicle 5 according to FIGS. 1 to 6, comprises a chassis 6' and a body 7 '. On the rear end face 27, on which the two luminous marking devices 12 'are also arranged, an operating handle 40 is provided for the operator.

The picking vehicle 5 'has eight receptacles 28 for objects. These gondola-shaped receptacles are guided in a paternoster-like manner in two circular guides 29 lying opposite one another, the center points 30 of which define an axis 31 running transversely to the direction of travel. They are suspended at the end on two link chains 32, which run in synchronism with one another along the circular orbit 33 in the guides 29. A link motor (not shown) acts on the link chains 32 which, controlled by the electronic data processing unit, in each case a selected receptacle in front of the Brings loading and unloading opening 34 which is arranged in the cover 35 provided on the end face 27.

The receptacles 28 are detachably suspended from the link chains 32. For its identification, each receptacle 28 has a coding carrier 37 known as such.

A reader 38 in the form of a transponder reader 39 is arranged on the picking vehicle 5 '.

For the order picking vehicle 5 "according to FIG. 10, there is essentially the same as for the order picking vehicle 5 'according to FIG. 9. However, not eight, but rather five receptacles 28" are provided here, which are made correspondingly larger with the same overall dimensions of the order picking vehicle 5 " Another difference is that the receptacles are detachably suspended from two side wheels 53 which have a star-shaped contour and are rotatably mounted about a horizontal axis 54 which extends transversely to the direction of travel F. On one of the two wheels 53 acts the drive motor 56 forming the adjusting drive 55 for the receptacles 28 ″.

The order picking vehicle 5 "according to FIG. 10 has a cladding, which is not shown for the sake of better representation, which extends over the sides, the rear end face 57, the top side 58 and the front end face 59 of the order picking vehicle and only in the area of the operating handle 40 leaves an access opening to the receptacle 28 ″ located there in each case open. In the area of the front end, the cladding can be opened like a blind in order to be able to remove receptacles from the order-picking vehicle 5 ″ be moved up to a conveyor belt in such a way that the receptacles are automatically placed on a feed table of the conveyor belt when the wheels 53 are turned downwards at the front.
