Handling system for handling objects in a vehicle, storage device and method for handling objects in a vehicle

Abstract

A handling system for handling objects in a vehicle comprises a storage apparatus that is positionable outside a vehicle cabin, an access device that is positionable in a vehicle cabin, and a transport device for transporting objects between the storage apparatus and the access device. The storage apparatus comprises a storage space and a connection station that is connectable to the transport device, wherein the storage apparatus comprises at least one drive device for moving carriers on which objects to be stored are held. The handling system comprises at least one guiding device that with the drive device guides the carriers on at least one circular path within the storage space. The storage space thus comprises a vertical flat shape that results in a significantly smaller reduction in the available cargo volume in a vehicle, while at the same time maximizing the design space available for passenger seats.

DETAILED DESCRIPTION

(13) The following detailed description is merely exemplary in nature and is not intended to limit the present disclosure or the application and uses of the present disclosure. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

(14) According to FIG. 1 the handling system 2 according to the various teachings of the present disclosure comprises a storage apparatus 4 with a storage space 6 and a planar frame 8, wherein the frame 8 comprises a connection station 12 connected to a transport device 10, by means of which connection station 12 a connection between the storage space 6 and an access device 14 is created.

(15) The special feature of the handling system 2 according to the various teachings of the present disclosure comprises the storage apparatus 4 being designed to move carriers 16, which are designed to carry objects to be stored and to be conveyed, on at least one circular path within the storage space 6. In this arrangement the circular path encompasses a movement of the carriers 16 past the connection station 12 so that the transport device 10 by way of the connection station 12 is generally always in a position to wait for the approach of a predetermined carrier 16 to the connection station 12, and to convey the object situated on the aforesaid to the access device 14, to convey the entire predetermined carrier 16 to the transport device 10, to convey an object from the access device 14 to a predetermined empty or only incompletely taken up predetermined carrier 16, or to convey a predetermined carrier 16 to the storage space 6.

(16) It is understood, for maintaining special energy efficiency on board the vehicle and in order to save resources generally, to carry out rotary movement of the carriers 16 in the storage space 6 typically only at those times when access to objects or carriers 16 within the storage space 6 is to take place.

(17) Generally, the individual carriers 16 comprise a marking means 18 that may be recognized by a mark recognition device 20, wherein the mark recognition device 20 is generally situated in a region adjacent to the connection station 12. Accordingly, if a predetermined carrier 16 that comprises an individual marking means 18 is desired, a common movement of all the carriers within the storage space 6 could be initiated. The mark recognition device 20 would then recognize the approach of the predetermined carrier 16 to the connection station 12 and subsequently initiate deceleration of all the carriers 16 so that the predetermined carrier 16 is positioned directly at the connection station 12. At this point access to the predetermined carrier 16 or to the object situated thereon may then take place, for example, in that the object is removed and is transported to the access device 14, or in that an object coming from the access device 14 is placed on the predetermined carrier 16.

(18) Marking means 18 could, for example, be implemented by means of RFID tags or barcode stickers that may be read by mark recognition devices 20 in the form of RFID reading devices or barcode scanners.

(19) Such a storage apparatus 4 provides an advantage in that the mechanical implementation is considerably simpler than the use of a robot arm or the like, which needs to take objects from a shelf or needs to replace them back on the shelf. Such a robot arm must under any conditions, i.e. even during vibration of the vehicle during its normal operation, be three-dimensionally movable in a precise and reproducible manner. In contrast to this, circular movement of individual carriers 16 may be implemented very easily, and the positioning accuracy may be less than in the case of the above-mentioned robot arms. Furthermore, as a result of the generally exclusively planar movement, the resulting storage device is very flat when compared to storage rack solutions, and may thus be arranged in regions close to the floor or ceiling (crown) of a vehicle, without there being a need to keep free a dedicated storage space in a vehicle.

(20) The carriers 16 may be of any design; for example pallet-like carriers could be used; frame-like carriers that only comprise receiving flanges; box-like elements that are open on one side, or the like.

(21) For better utilization of a surface available as a storage space and for speeding up the possible access to individual carriers 16, it might be advantageous to provide several circular paths in the storage space 6, on which circular paths carriers 16 may run parallel to each other or concurrently. This is shown in FIG. 2.

(22) For reversing the direction, the carriers 16 need not necessarily be rotated by about 180°. Instead it would also be imaginable and sensible to merely deflect the movement path of the carriers 16 while maintaining their orientation.

(23) FIG. 2 shows a multitude of carriers 16 that may be moved in a storage space 22 on several circular paths. The individual circular paths may be implemented by guiding devices and drive devices (neither of them shown in FIG. 2).

(24) FIG. 2 also shows that a connection station 24 communicates with a transport device 26, while at the same time being able to establish contact with any desired carrier 16. By implementing the circular movement in the storage space 22, individual carriers may travel towards the connection station 24, or away from the connection station 24. By means of targeted control of the movement of the individual carriers 16, accordingly a predetermined carrier may reach the connection station 24 in that it is carried along to the connection station 24 in the flow of the other carriers 16.

(25) The exemplary illustration in FIG. 2 with several guide walls 28, 30, 32, 34 and 36, arranged so as to be parallel to each other, makes it possible for several circular tracks to overlap or intersect, which in principle also makes it possible to provide more complex movement tracks. For example, individual carriers 16 could carry out a circular track around the guide wall 36. At the same time, carriers 16 may also move on a circular track around the guide wall 34, which is arranged so as to be adjacent and parallel to the guide wall 36. The carriers 16 that are moved around the guide wall 34 and that at the same time are also adjacent to the guide wall 36 could correspondingly, by alternatingly initiating circular movement tracks around the guide wall 36 and the guide wall 34, in the drawing plane “jump” downwards a row, and in this manner with continuous circular movement around the guide wall 34 ultimately reach the connection station 24 relatively quickly.

(26) In FIG. 2 the individual carriers 16 comprise numbers T1-T50. To illustrate the interaction of the various circular movements, the carrier T7 will be considered in more detail below, which carrier T7 in the drawing is situated at the lower end of the guide wall 28. As a result of clockwise circular movement, the carrier T7, around the guide wall 28, may reach a position at which at present the carrier T16 is positioned, i.e. now at the top of the guide wall 28 to the left of the storage space 22. As soon as this position has been reached, a clockwise circular movement of all the carriers 16 arranged adjacent to the guide wall 30 could take place. Consequently the carrier T7 could reach the position which in the drawing is presently taken up by carrier number T21. This is directly adjacent to the connection station 24 so that a mark recognition device 20 could recognize the marking means 18 of the carrier T7 and could decelerate the movement of the carriers 16 in the storage space 22 in order to cause loading or unloading of this carrier T7.

(27) This shows that storage spaces 22 according to the various teachings of the present disclosure, which are extensive in terms of surface area, may comprise a multitude of carriers 16 that as a result of the circular movement may very easily be moved in front of a loading and unloading station in the form of the connection station 24.

(28) Controlling the movement generally takes place by way of a processing unit comprising a computer program or the like, which processing unit matches the particular requirements of the corresponding storage space 22 so that with a minimum movement sequence each predetermined carrier may be moved to a connection station 24.

(29) The computer program comprises a stop function for the entire system in case of the occurrence of turbulence of a selected magnitude, during which turbulence safe handling is no longer ensured. In addition to this, at the same time instructions could be issued for all the still movable trolleys to be secured at predetermined locations.

(30) Because of the generally flat design of a storage space and a large storage space area that may be accessed by way of one or several circular paths the handling system 2 according to the present disclosure is generally well suited for use in vehicles, as shown in FIG. 3 with reference to a commercial aircraft.

(31) FIGS. 3 and 3a-3d show an aft region 38 of an aircraft, in which, for example, an aircraft galley 40 is arranged immediately in front of a pressure bulkhead 42. This aircraft galley 40 is special in that it comprises only two parking positions 44 in which trolleys may be parked. With the use of the handling system 2 according to the various teachings of the present disclosure it is not necessary to carry an excessive number of trolleys in the aircraft, which trolleys already at the time of delivery comprise food and beverages and in parking positions wait to be used. Instead, FIG. 3 shows the way in which underneath a cabin floor 46 a storage space 48 comprising carriers 16 could be integrated, which carriers 16 reach a transport device 54 by way of a connection station 52, from where they may be moved by means of an access device 56. From the access device 56, objects 50 that are arranged on the carriers 16 may be removed and placed into corresponding trolleys.

(32) If the objects 50 comprise, for example, prepared catering service boxes containing food and beverages on trays, the aforesaid may be moved from the access device 56 to the trolleys, may then be served to passengers, and finally empty catering service boxes comprising waste may be conveyed back to the storage space 48 by way of the access device 56. This obviates the need to provide generous storage spaces in the aircraft galley 40 and the need to provide a multitude of trolleys, and consequently the design space usually taken up by an aircraft galley may be equipped with passenger seats. As a result of this, the seating capacity in the aircraft may be increased, wherein as a result of the very flat design of the storage space 48 no excessive limitation of container storage areas in the cargo hold takes place, or as an alternative, an always adequately dimensioned cargo hold 49 for accommodating baggage, oversize baggage or loose cargo may be provided.

(33) The example of FIGS. 3 and 3a-3d shows a storage space 48 that is similar in design to the storage space in FIG. 2. Due to the width of larger commercial aircraft it would also be imaginable to use wider storage spaces that comprise still further guide walls that allow a still greater number of circular movements.

(34) In order to be able to unblock objects 50 that have accidently become wedged or jammed, an access flap 53, which for example is arranged in the cabin floor 46, could be integrated in the cabin of the vehicle, through which access flap 53 it would be possible to gain direct access to the storage space 48.

(35) The transport device 54 shown in FIGS. 3 and 3a-3d is designed as a vertical transport device. A subsequent access device 56 could be designed in the manner of an elevator opening or lift opening, as diagrammatically shown in FIG. 4.

(36) The access device 56 could, for example, comprise a supporting frame 58 on which a conveyor 60 is arranged. During loading and unloading objects 50, the supporting frame 58 could be made to align, for example, with the connection station 52 of the storage space 48 so that an object 50 could be removed from a carrier 16 and moved onto the supporting frame 58, for example by means of the conveyor 60. As an alternative to this it would also be possible to move the complete carrier 16, including the object 50 situated thereon, onto the supporting frame. FIG. 4 shows the latter case, which means that the entire carrier 16 rests on the supporting frame 58, and, by way of the access device 56, may be brought above the cabin floor 46 of the aircraft where it may be unloaded. Unloading involves, either by means of the exemplary conveyor 60 or manually, removing the carrier 16 from the access device 56 and, for example, inserting it directly into a trolley provided by the access device.

(37) In the exemplary illustration from FIGS. 3 and 4 the transport device 52 is designed as a vertical transport device to which the access device 56 also joins vertically. In order to protect the well, required for this, to the storage space 48 to prevent objects, for example waste, small items and the like, from falling into said well, a closing device 64 is arranged in that location, which closing device 64, for example, closes the well completely in the manner of a roller shutter. Prior to movement of the access device 56 this closing device 64 is opened again, and the supporting frame 58 may be moved in the direction of the storage space 48.

(38) The sidewalls of the vertical transport device 52 comprise vertical guide profiles for accommodating the bearing rollers 68 for safe and reliable up and down movement of the carriers 16.

(39) Guidance of the individual carriers 16 within the handling system 2 according to the various teachings of the present disclosure may be achieved in various ways. Mechanically simple, robust and above-all reliable guiding devices are, of course, generally desirable, because they clearly improve operational safety and reliability while minimizing the danger of a carrier 16 suddenly becoming stuck in the region of the storage apparatus according to the present disclosure and having to be manually freed, or other unforeseen and undesired events occurring. FIG. 5 shows a mechanically generally simple but also very robust and thus reliable guiding device.

(40) FIG. 5 shows a small section of a carrier 16 which carries an object 50. On an outside 66 of the carrier, bearing rollers 68 are arranged that are formed so as to correspond to a guide groove 70. In FIG. 5 the guide groove 70 is shown in profile section; it could extend along a desired length and could extend in a straight or linear manner, or so as to be curved in some sections. By means of such a guide groove 70, because of the flush engagement of the bearing rollers 68, the carrier 16 is guided along a predetermined track so that the drive of the carriers 16 may also be designed so as to be mechanically relatively simple. It is not mandatory for the drive device to be matched to move the driven carrier 16 on a predefined track at the desired precision.

(41) In the example shown the guide groove 70 comprises such a profile that extends from a center axis or symmetry axis 72 towards the outside so that that end of the guide groove 70, which end is opposite a base 74, is wider than the base 74. As a result of this the guide groove 70 provides a funnel effect that is able to receive even relatively imprecisely positioned bearing rollers 68 in order to guide them along the predetermined track while fully receiving them. This effect could be reinforced in that the bearing rollers 68 comprise a matching contour that narrows towards the outside when viewed from the carrier 16.

(42) As shown in FIG. 5, the guide groove 70 may be arranged on a carrier 16 so that, for example, adjacent carriers 16 could be mutually self-guiding. There is a positive side-effect in that carriers 16 moving one behind the other do not require an individual drive, but instead in that a carrier 16 “pushes” one following carrier 16 or several following carriers.

(43) In a manner that differs from the above, FIG. 6 shows that a guide groove 70 could also be arranged on a structural component 76 in order to guide the bearing rollers 68 and thus the carriers 16 along a fixed predetermined track. At the same time, in order to maintain compatibility, the same structural component 76, on a side opposite the guide groove 70, could also comprise a projection 68 by means of which guidance of a carrier 16 could take place, on which projection 68 a guide groove 70 is arranged. The structural component 76 could be designed as one of the guide walls 28, 30, 32, 34 or 36 from FIG. 2. The aforesaid do not extend fully along the entire storage space 22, and consequently in the storage space 22 there are regions in which two carriers 16 could guide themselves relative to each other.

(44) In regions in which a reversal of the direction is to be carried out within the storage space it may at times happen that at certain positions adequate support by a structurally-rigid position underneath the carriers 16 may not be ensured. This may happen where several drive devices are arranged in several rows relative to each other, during changeover from one row to the next row, but at least on diagonally traversed positions no adequate support by the drive devices may be present and a carrier could carry out a tilting movement. This would entail a risk of the object situated on the carrier 16 falling off, or of the carrier 16 tilting.

(45) In FIGS. 7a and 7b longitudinal safety supports in the region of track switches are proposed. The safety supports 78 could, for example, comprise a structural component 80 that is attached in a structurally-rigid manner to a base 82 and on an opposite end to the base 82 a support profile 84 is provided on which a carrier 16 may rest. A simple design of such a safety support 78 could, for example, comprise a support profile made of Teflon or some other similarly suitable material. Likewise, the spherical support 86 shown in FIG. 7b might be advantageous, in which spherical support 86 a sphere 88 is held in a wear-resistant manner, which sphere 88 could support even relatively heavy carriers 16.

(46) FIG. 8 shows a drive device 90 comprising a lateral drive unit 92 and a longitudinal drive unit 94. Both the lateral drive unit 92 and the longitudinal drive unit 94 comprise two motor units 96 in which in each case a friction wheel 98 is driven. In the lateral drive device 92 the rotary movements of the two friction wheels 98 are synchronized by way of a linear movement element 100; the same applies to the longitudinal drive device 94. The lateral and longitudinal drive devices 92 and 94 are controlled independently of each other and are generally operated separately of each other. When this is required, the friction wheels 100 could generally be pivoted or hinged to the transporting carriers 16, and during the switching-off procedure could be pivoted or hinged back. In the region of a track switch with a change in direction of a circular path, for example, a carrier could move to the drive device 90 on a longitudinal path, after which the longitudinal drive unit 94 is switched off and then the lateral drive unit 92 is started up. This means that the corresponding carrier would first carry out a lateral movement and then a vertical movement so that at first the longitudinal drive unit 90 is pivoted to the carrier 16 and could be made to establish frictional contact, followed by the lateral drive unit 92.

(47) Movement of the carrier 16 significantly depends on the design of the drive devices so that a multitude of drive devices 90 would have to be arranged in a storage system according to the various teachings of the present disclosure. It may not be necessary to provide a drive device 90 at every imaginable position across which a carrier 16 moves. However, it generally may be ensured that drive devices are positioned generally at the positions in which the carriers need to carry out a reversal of direction. At the same time it should generally be ensured that at all times a carrier 16 is in full contact with two friction wheels 98, because otherwise a chain of carriers 16 arranged one behind another, which carriers push each other along, may suddenly come to a standstill.

(48) In order to prevent the objects 50, in the case of excessive turbulence, relative movement, oscillation or the like of the vehicle, from lifting from the respective carriers 16, generally above the frame 8, catching profiles 102 are arranged which for example comprise profile bars that have an L-profile and are positioned in such a manner that the outer edges of the respective objects may engage the catching profiles 102, without however jamming and becoming stuck.

(49) FIG. 10 shows a block diagram of the method according to the various teachings of the present disclosure. The method according to the various teachings of the present disclosure for handling objects in a vehicle among other things comprises initiating 104 a movement of carriers in a storage space of a storage apparatus on a first circular path. This may, for example, take place in that in the cabin of the corresponding vehicle, objects are removed from the storage apparatus and are loaded onto trolleys or the like. A carrier on a connection station in the storage space is accessed 106, and this carrier is loaded or unloaded 108. This takes place by conveying an object situated on the carrier, or by conveying the entire carrier, by means of a transport device, between the storage apparatus and an access device. Prior to and after removal or insertion of an object from/in the access device a closing device between the transport device and the access device is activated 110 in order to protect the storage apparatus from any unintended effect as a result of access by foreign objects or the like.

(50) The method according to the various teachings of the present disclosure could, furthermore, comprise the reading of marking means and the stopping 112 of the storage apparatus, for example in the case of considerable movement of the vehicle, when an end position has been reached by a predetermined carrier with an object to be handled, or when a handling process has been completed.

(51) Finally, FIG. 11 shows an aircraft 114 comprising a handling system according to the various teachings of the present disclosure, several access devices 14, and a storage apparatus 4 arranged above a cargo hold. As an alternative or in addition the storage apparatus 4 may also be arranged above the passenger cabin.

(52) While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the present disclosure in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the present disclosure as set forth in the appended claims and their legal equivalents.
