Description

Technical area

The invention relates to a device for clearing used trays, which are provided with crockery, cutlery, glasses, food waste, etc., and / or for the elimination of residual dirt from trolley. In large kitchens, canteens or in dining car or aircraft used trays are inserted into trolleys one above the other in individual compartments and stored until the trays used are a cleaning supplied.

State of the art

Out DE 10 2006 039 434 A1 is a fixing device for transport vehicles of transport containers in cleaning systems known. The in passenger aircraft, canteens, etc. z. B. used dolly or transport containers generally include a number of subjects in which the trays are prefabricated with pre-portioned food or drinks and optionally, such. B. on long-haul flights, reheated and then transported by means of the trolley (trolleys) or transport container through the passenger cabin or the central aisle of a railway car. The individual subjects are successively emptied.

In such trolleys (trolleys) or transport containers and the used dishes, used glasses and possibly trays, cutlery and the like are given back and transported away.

When unloading an aircraft or when unloading a railway car or when rolling out of transport containers from canteens after returning the used dishes, the used trolleys or transport containers after removal of the used dishes, cutlery used or the like, a cleaning supplied so that these can be used again as soon as possible. A manual cleaning of used, food or beverage residues containing mobile trolleys or transport container is too time-consuming, so they are cleaned in cleaning equipment.

Prerequisite for effective cleaning of the interior of the trolley (trolleys) or transport container is a previous clearing step, during which the previously occupied with the trays with food waste, cutlery and the like to be cleaned interior spaces of the trolley (trolleys) or transport containers are cleared. This is currently done either manually and is associated with a fairly high staff costs, and this work is ergonomically considered to be tiring, since it is associated with a relatively frequent stooping. There are also semi-automatic or fully automatic Wagenausräumer in which the individual trays are pulled out of the car one after the other. The previously known systems therefore work relatively slowly and often not sufficiently trouble-free.

Disclosure of the invention

The invention has for its object to provide a tray transport car, are taken in the trays are substantially stacked in individual compartments, in one operation and clear a cleaning device, such. B. a Abräumband supply.

According to the invention, this object is solved by the features of patent claim 1.

The device proposed according to the invention comprises a frame construction, to which trolleys to be cleared are brought up in a stack-receiving carriage manually or else via a conveyor system. The trolleys, in which the trays are received in stack form, occupy a tray scavenging position relative to the frame construction of the scrapping device proposed according to the invention. So z. B. are to be cleared tray trolley pushed onto a conveyor belt and spent by this in the Ausräumposition.

The inventively proposed Ausräumvorrichtung comprises a gripper mechanism. The gripper mechanism is movable in a separate, movable within the frame construction frame construction. Corresponding to the number of trays arranged in stack form in the tray transport carriage, the gripping mechanism likewise comprises a plurality of movable gripping devices arranged in stack form. These drive - preferably with open grippers - in a likewise arranged in the frame construction of the invention invented clearing device, but vertically movable transport device. This vertically movable transport device is a temporary storage. The grippers pass through receiving rails of the vertically movable transport device (temporary storage) until they face the individual trays arranged in stack form in the tray transport carriage. In this state, the grippers are open. The opening path that the grippers pass from their closed position to their open position is on the order of about three tray thicknesses, so that in In one operation up to three empty, stacked trays can be gripped by a gripper.

Since the gripper mechanism moves in the horizontal direction on the tray dolly and in stack form, d. H. In individual floors arranged one above the other arranged gripper is in the approached to the tray transport vehicle state each of the arranged in the tray transport trolley to be cleared trays an open gripper opposite.

Arrived at the individual trays, the grippers are closed. Then the gripper mechanism moves in toto, d. H. simultaneously, so that each trapped by a single gripper tray or three superimposed empty trays are retracted in the horizontal direction in the vertically movable transport device (buffer). This means that the tray trolley is emptied in one operation. When driving back the retracting in the horizontal direction in the frame structure gripper mechanism and reaching the end position of the gripper with respect to the movable in the vertical direction transport device (buffer), the trays in the individual transport planes of the transport device (cache), open the gripper and finally drives the complete gripper mechanism back to its original position, in which the grippers remain open.

Subsequently, the now loaded with the cleared trays transport device (cache) moves in a vertical upward direction.

If the transport device (intermediate store), which can be moved in the vertical direction, has reached its maximum lifting position, i. H. if it has reached its Ausschiebeposition, moves this within the frame structure of the excavator in the horizontal direction in front of a Tablettausschiebeeinrichtung. In the Ausschiebeposition a series of trays is pushed by the Tablettausschiebeeinrichtung in a feed of a Tablettabräumbandes. This is done within a movement.

As soon as the trays are pushed out of the transport device (intermediate store) located in the push-out position, which can be moved in the vertical direction, the tray puller moves back into its rest position.

Now the trays are separated, which, for example, by means of a lift, such. B. can be done by means of a paternoster, deposited on a Tablettabräumband and transported away on the Tablettabräumband. As soon as an activation of a parking space on the tray removal belt has taken place, the process is repeated until the tray storage of the elevator is completely emptied.

After the individual trays have been placed on the tray removal belt, the trays are continuously conveyed away by this, so that finally all tablets originally contained in the tray transport car of the cleaning device, in particular a continuous dishwasher or the like, can be supplied.

After all trays have been cleared from a tray trolley in a discharge cycle - as described above - the cleared tray trolley automatically moves on a parking space and arrives at a Schmutzschmutzausräumstation. Arranged essentially on a plane takes place in a Restschmutzausräumposition a tendency to empty the cleared cleaned tray trolley to z. B. 5 ° in the direction of the stationary frame construction. About stripping elements, which are arranged extendable and retractable, residual dirt, cutlery or food particles from the individual levels or the guide rails for the trays serving elements of the tray transport car are pulled out. To clean the floor, a transversely movable residual dirt evacuator moves from the frame construction laterally into the tray transport trolley. The emptied and freed of residual debris tray transport carriage remains in the inclination, which may be 5 ° or slightly more, and is supplied in the inclined position remaining of a tray carwash washing system and leaves the actual Tablettausräumvorrichtung.

By inventively proposed device for clearing tray trolley or trolley (trolleys), as used in passenger aircraft or railroad cars or the like, it is possible to clear the trolley quickly and reliably, so that they can be fed to a machine cleaning. In addition to the fully automatic clearing of said tray transport car by the inventively proposed device, a pre-cleaning of the tray transport car is possible after they are cleared. This can be done in parallel to the separation of the previously cleared from the tray trolley trays. The inventively proposed device also allows a continuous loading of a Geschirrabnahmestation and subsequently a continuous dishwasher with emptied or empty trays, so that a continuous process can be established, within which no manual intervention - unless it There are problems with separation - more is needed. In addition, the simultaneous removal of all trays does not result in excessive waiting times for possible operators who provide or pick up the tray transport cars at the clearing station.

2 shows that the clearing and separating device 10 a transverse side 28 has, compared to the long side 26 as shown in 1 builds shorter. The frame construction 12 includes in addition to a in 2 only schematically indicated operating unit 150 a gripper mechanism 52 , The gripper mechanism 52 includes a number of single grippers 54 which are arranged stacked in a substantially vertical direction one above the other. The division in which the single gripper 54 in the vertical direction within the movable gripper mechanism 52 are arranged, corresponds substantially to the pitch of slide rails 20 to be cleared tray trolley 16 , 2 shows that the frame construction 12 the inventively proposed evacuation and separation device 10 In addition, a vertically movable transport device 60 (Latch) comprises, in the manner of a lift, such. B. a paternoster. The vertically movable transport device 60 (Latch) is in the vertical and horizontal directions within the frame construction 12 movable. The vertically movable transport device 60 (Buffer) comprises a number of receiving rails 62 , which also essentially correspond to the vertical division, in which the single gripper 54 within the feed direction 58 movable gripper mechanism 52 are arranged. The division of the arrangement of the single gripper 54 the gripper mechanism 52 in the vertical direction corresponds to the pitch of the arrangement of the receiving rails 62 the vertically movable transport device 60 (Buffer), which in turn the vertically extending division of the slide rails 20 the tray trolley to be cleared 16 equivalent.

As the representation of 2 can be further removed, is the gripper mechanism 52 in the feed direction 58 traversable. The gripper mechanism 52 is powered by a feed drive 68 in the feed direction 58 and driven in the return direction. From the illustration according to 2 it appears that in the in 2 illustrated rest position of the gripper mechanism 52 the individual grippers 54 all an open position 56 accept.

2 further shows that on the input page 50 the tray dolly 16 on the conveyor level 14 has arrived. The tray transporter 16 includes in its slide rails 20 stacked trays arranged one above the other 64 , On each of the trays 64 on the slide rails 20 in the walls 22 the tray dolly 16 rest, there are dishes, cutlery, leftovers, indicated in the illustration according to 2 by reference numerals 66 , As shown in the illustration 2 In addition, the individual trays are 64 into the slide rails 20 of the tray car 16 more or less deeply inserted. This means that these too - as in 2 shown - can survive to the front, ie not necessarily on the rear wall 22 of the tray car 16 issue.

3 shows that the gripper mechanism is extended in the feed direction from its rest position in the direction of the trays located in the tray transport carts.

As the view is correct 3 can be seen, moves within the frame construction 12 the inventively proposed evacuation and separation device 10 recorded gripper mechanism 52 in the feed direction 58 towards the tray dolly 16 , In this are - more or less deep along the slide rails - trays 64 on which crockery, cutlery and leftovers as well as waste such. As napkins or the like are received, taken in substantially stack form. The gripper mechanism 52 drives in its entirety - driven by the feed drive 68 in the feed direction 58 - on the tray transport car 16 to. The single gripper 54 the gripper mechanism 52 are in their open position 56 , As 3 shows moves the gripper mechanism 52 parallel to the transverse side 28 the frame construction 12 the inventively proposed evacuation and separation device 10 by the transport device movable in the vertical direction 60 (Buffer). As 3 shows comprises the transport device 60 (Latch), which has moved to its lower stroke position, a number of receiving rails 62 , on the one hand to the division of the slide rails 20 in the vertical direction of the tray transport vehicle 16 correspond and on the other hand to the division of the arranged in the vertical direction single gripper 54 the gripper mechanism 52 correspond.

3 shows that the gripper mechanism 52 in toto - the vertically movable transport device 60 (Latch) happened - to the front of the tray car 16 moved up. The in their open position 56 driven single gripper 54 enclose in the 3 position shown an edge of a tablet 64 , on the crockery, cutlery, leftovers or napkins and the like, indicated by reference numerals 66 , are indicated. In this regard, it should be noted that by the in its open position 56 driven single gripper 54 the gripper mechanism 52 Also up to three superimposed trays 64 can be overlapped when closing the respective single gripper 54 can also be taken.

3 shows that the feed drive 68 for the gripper mechanism 52 in toto with this facial expression in the feed direction 58 (compare illustration according to 2 ) can be moved. A reset drive for the gripper mechanism 52 is with reference numerals 69 designated.

In the illustration according to 3 is the gripper mechanism 52 - The individual floor-shaped superposed single gripper 54 comprising - to the front of the trays 64 in the tray cart 16 be transported, moved up.

The representation according to 4 It can be seen that the clearing and separating device 10 in the state shown there, the edges of trays 64 through in open position 56 single gripper 54 grasps. The single gripper 54 the gripper mechanism 52 are - as in 4 indicated - from their open position 55 simultaneously in their closed position 72 transferred. In the closed position 72 have the single gripper 54 the gripper mechanism 52 either the edge of a single tray 64 taken or a number of superimposed trays 64 seized or no tray 64 taken because in the corresponding vertical position no tray 64 into the slide rails 20 of the tray car 16 was inserted.

4 further shows that the single gripper 54 the gripper mechanism 52 the individual trays 64 in the slide rails 20 of the tray car 16 are included, can take in any insertion position, as in the feed direction 58 moving gripper mechanism 52 when approaching the individual in the slide rails 20 arranged trays 64 these in the slide rails 20 of the tray car 16 shifts until this on the back panel of the tray car 16 issue. Then those in the slide rails 20 of the tray car 16 stacked trays in stacked form 64 all simultaneously by the Einzelgreifer 54 the gripper mechanism 52 be taken as soon as the individual grabs 54 from her open position 56 in their closed position 71 be transferred.

The representation according to 5 can be seen how the from the slide rails of the tray transport car 16 conveyed trays are transferred into the vertically movable transport device.

The representation according to 5 can be seen that the gripper mechanism 52 a return movement 74 which takes place through the closed individual gripper 54 grabbed trays including dishes, cutlery, etc., see position 66 , in the superposed receiving rails arranged 62 the transport device movable in the vertical direction 60 (Temporary storage) are transferred. The in the sidewalls 22 of the tray car 16 provided slide rails 20 are visible depending on the feed in the return movement 74 located single gripper 54 , During the return movement 74 the tray truck remains 16 in its rest position along the long side 26 the frame construction 12 The inventively proposed Ausräumvorrichtung 10 , With reference number 150 is in the illustration according to 5 an operating unit, ie a keyboard or a touch screen or the like. 5 further shows that the vertically movable transport device 60 (Buffer) is in its lowered position, ie in the vertical direction exactly assumes a position in which the slide rails 20 the side walls 22 parallel, ie lying in a plane with the mounting rails 62 the vertically movable transport device 60 (Temporary storage) are aligned. Thus, a transfer of dishes, cutlery and the like, compare position 66 provided trays 64 in the receiving rails 62 the vertically movable transport device 60 (Intermediate) disability-free possible and without any items during the transfer from the tray dolly 16 in the vertically movable transport device 60 (Cache) fall to the ground or the movement of the single gripper 54 that the return movement 74 run simultaneously, possibly obstruct. The tray transporter 16 is located during the in 5 illustrated transfer of trays 64 braked and secured against rolling on the conveyor plane 14 , In 5 only schematically indicated are successively through the trays 64 released slide rails 20 to recognize. In addition, the tray dolly includes 16 a floor 18 as well as by reference numerals 22 indicated side walls, in which in turn the slide rails 20 are included. By means of the return drive 69 becomes the gripper mechanism 52 returned to its rest position and thereby leads the return movement 74 out.

6 It can be seen that all trays previously in the tray transport car 16 were stored, now in the vertically movable transport device 60 (Temporary storage) are transferred. From the illustration according to 6 also shows that at this time all trays 64 completely from the mounting rails 62 the vertically movable transport device 60 (Buffer) are included, the single gripper 54 the gripper mechanism 52 open and the gripper mechanism 52 through the feed drive 68 successively the return movement 74 performs until the gripper mechanism 52 in toto has reached its resting position again. The rest position of the gripper mechanism 52 is by reference numerals 78 , see. Representation according to 7 , designated.

From the illustration according to 6 it turns out that the tray dolly 16 now completely cleared, the vertically movable transport device 60 (Cache) all trays 64 receives the single gripper during the further execution of the return movement 74 her open position 56 accept and as shown in 6 not yet completely the resting position 78 is reached.

From the illustration according to 7 shows that the gripper mechanism 52 in their resting position 78 is transferred. The feed drive 68 and the one above the other in a stacked single gripper 54 the gripper mechanism 52 are on a parallel to the transverse side 28 the frame construction 12 recorded movable carriage and in the illustration according to 7 in the resting position 78 by a distance from the edge of the vertically movable transport device 60 (Cache) reset.

This is necessary to ensure that at a by reference numerals 80 indicated lifting movement of the vertically movable transport device 60 (Buffer) whose Auffahrbewegung is not hindered.

The empty tray dolly 16 can now from the Ausräumposition on the conveyor plane 14 be removed and the next, to be cleared tray trolley 16 opposite the long side 26 the frame construction 12 be positioned. Also the gripper mechanism 52 or the single gripper 54 are in their open position 56 and are ready for the next clean-up cycle.

As shown in the illustration 7 it can be seen, which interferes with the trays 64 loaded, movable in vertical direction transport device 60 (Temporary storage) by means of the drive 30.1 to the top and transported in individual subjects stockpiled trays 64 including dishes, cutlery, dishes, etc. placed on it in a separating position.

The representation according to 8th is a view of the within the frame construction in the vertical direction raised, vertically movable transport device and the separating device can be seen.

8th shows that in the longitudinal direction, ie parallel to the longitudinal side 26 the frame construction 12 shown, movable in the vertical direction transport device 60 (Buffer) builds deeper than from the views of the input pages according to the 2 to 7 evident. From the representation of the long side according to 8th shows that the vertically movable transport device 60 (Cache) a number of bins 92 . 94 . 96 having. 8th shows that according to the loading of the likewise three compartments having tray trolley 16 also empty positions 88 in which there are no trays loaded with cutlery, crockery and leftovers 64 have been inserted.

The representation according to 8th It can be seen that the vertically movable transport device 60 (Cache) in their three partitions 92 . 94 . 96 on the there on the side walls facing each other receiving rails 62 , the trays 64 contains.

8th shows that moved to its vertical position, vertically movable transport device 60 a horizontal movement 86 executes and within the frame construction 10 on the separating device 32 drives, serves the drive 30.2 ,

This is the lifting movement 80 passing through, in the vertical direction movable transport device 60 (Cache) on rails 82 , which are parallel to each other in the frame construction 12 are provided, in the direction of the arrow 86 method. In order to enable this method, the transport device movable in the vertical direction has 60 (Buffer) in its upper part a number of roles 84 on to the by the arrow 86 according to the 8th indicated to be able to accomplish in a horizontal direction displacement operation.

8th shows the separating device 32 in her side view. The subjects 92 . 94 . 96 having, in the vertical direction movable transport device 60 (Cache) is still next to this and does not obscure this. The separating device 32 includes a drive, see position 42 , as well as a number of endless links 36 at which projections 38 or the like may be attached. The two in the vertically extending columns of the singulator 32 provided endless members 36 be through the drive 42 operated synchronously in relation to each other, so that one between the protrusions 38 or support rails that extend into the drawing plane, to this recorded tray 64 always horizontal and not tilted. Furthermore, from the illustration according to 8th that the singulation device 32 a settling area 35 as well as a conveyor belt 34 for isolated trays 64 includes. The conveyor belt 34 is by the at the bottom of the separating device 32 provided drive 40 driven.

The moving in its vertical position, vertically movable transport device 60 (Cache) is made from the in 8th shown position according to the arrow 86 within a horizontal plane in front of the singulation device 32 the inventively proposed evacuation and separation device 10 hazards.

This condition is in 9 played.

In comparison to their position according to 8th is the vertically movable transport device 60 (Cache) with its first compartment 92 before in the drawing plane according to 9 behind this separating device lying 32 hazards. In this position are the in the individual subjects 92 . 94 . 96 on the existing mounting rails there 62 recorded trays 64 according to the drawing level 9 in the separating device 32 transferred. This happens successively with each of the subjects 92 . 94 . 96 , To each of the subjects 92 . 94 . 96 in which the trays 64 are arranged one above the other, in front of the separating device 32 to position, is the horizontal movement 86 the vertically movable transport device 60 required. The drive is used for this purpose 30.2 ,

The representation according to 9 It can be seen that in the state shown there, the first compartment 92 the vertically movable transport device 60 (Cache) exactly opposite the stationary in the frame construction 12 the clearing and separating device 10 arranged singulation device 32 located.

10 shows how the trays, which are stored in the vertically movable transport device, are transferred to the singulator. For this purpose, the stationary includes in the frame construction 12 recorded singulation device 32 a pusher 102 , The pusher 102 may be formed in a particularly simple and advantageous configuration as a longitudinally extending bar, as a tube or as a profile. This offers the advantage that in a lateral, ie horizontal movement of the pusher 102 a variety of trays 64 can be ejected automatically at the same time.

As the figure according to 10 can be removed, moves the elongated ejector 102 according to the arrow 104 in Ausschieberichtung and thus clears the vertically movable transport device 60 (Cache) empty. This means that when inserting the pusher 102 and its method in the Ausschichtungichtung 104 , all in the mounting rails 62 the vertically movable transport device 60 (Temporary storage) stored tablets at the same time from the receiving rails 62 pushed out and in a plane in the separating device 32 be transferred. The separating device 32 includes a number of the endless members already mentioned several times 36 recorded projections 38 or longitudinal rails, so that from the receiving rails 62 the vertically movable transport device 60 through the pusher 102 pushed out trays 64 from the singulator 32 be recorded. The separating device 32 in turn has the drive 42 over which the endless members 36 be synchronized with each other, so that when switching on the drive 42 the trays 62 towards the settling area 35 transported in an elevator-like manner, ie in the direction of the settling surface 35 be encouraged. In the downward movement of the endless members 36 recorded projections 38 These run on both sides of the conveyor belt 34 over and put a tray 64 on this. By the orbital movement of the endless members 36 within the columns of the separating device arranged parallel to one another 32 these are transported empty on the outside upwards.

10 shows the device for clearing and separating 10 from their transverse side 28 ago. The vertically movable to the drawing plane, vertically movable transport device 60 is on the rails 82 through the roles 84 movably received, so that each of the subjects 92 . 94 . 96 the movable transport device 60 (See illustration according to the 8th and 9 ) in front of the separating device 32 can be driven. About the then each activated pusher 102 become the in the individual subjects 92 . 94 . 96 the vertically movable transport device 60 stockpiled trays 64 at the same time from the receiving rails 62 pushed out and into the separating device 32 transferred

11 shows that the pusher 102 a return movement 108 performs. The pusher 102 has a substantially elongated appearance and is dimensioned so that this - in relation to its vertical longitudinal extent - all receiving rails 62 the vertically movable transport device 60 Overflowed (cache), ie all in these stockpiled trays can slide out.

11 It can also be seen that the vertically movable transport device 60 (Cache) in the upper area the rollers 84 having, with which the vertically movable transport device 60 (Cache) on the rails 82 Is mounted movable in the horizontal direction. The horizontal mobility of the vertically movable transport device 60 (Cache) within the frame construction 12 ensures that all subjects 92 . 94 . 96 before the separating device 32 can be driven.

The representation according to 12 it can be seen that after emptying the receiving rails 62 the vertically movable transport device 60 (Buffer) through the pusher 102 the trays 64 in the direction of the contact surface 65 be encouraged. This drives the drive 42 the endless members 36 synchronously such that the trays 64 standing on protrusions 68 or are included in the drawing plane extending rails are deposited on this and by this in the in the conveyor belt level 112 extending conveyor belt 34 towards the output side 100 the inventively proposed device for clearing and separating flat objects are promoted. The feed of the endless links 36 ie the continuous or discontinuous lowering of the trays 64 in the separating device 32 are received by reference numerals 110 indicated. The separating device 32 and the associated conveyor belt 34 are stationary in the frame construction 12 the device for clearing and separating 10 as proposed according to the invention, during a movement of the vertically movable transport device 60 (Buffer) both in the vertical and in the horizontal, ie in the plane of the representation according to 12 is possible, so all subjects 92 . 94 . 96 the vertically movable transport device 60 (Temporary storage) each with the separating device 32 aligned.

The representation according to 13 it can be seen that the feed 110 , ie the synchronous drive of the endless members 36 That causes the individual in the protrusions 38 or receiving rails of the separating device 32 supported tablets 64 towards the conveyor belt level 112 be encouraged.

As in particular the representation according to 15 can be removed, for this purpose, the cleared tray trolley 130 around a tilt angle 138 inclined. The angle of inclination is in the order of between 0 and 15 ° and is dependent on the width of the conveyor track 14 , the height of the tray dolly 16 as well as other parameters. From the illustration according to 15 it turns out that those in the funding level 14 along the long side 26 the frame construction 12 promoted tray trolley 130 who have a passion 136 have been adopted to improve the stability of hooks or the like on a surface of the frame structure 12 be supported. The representation according to 15 In addition, it can be seen that the slide rails 20 the cleared tray trolley 130 are empty and a transversely movable Schmutzschmutzausräumer 140 the floor 18 the cleared tray trolley 130 is cleaned. This may have the appearance of a slider or a broom and serves on the floor 18 remaining leftovers, dirt, cutlery or napkins and the like from the cleared trolley 130 to remove. The fact that the cleared tray trolley 130 the inclination 136 in terms of the frame construction 12 ingest, improves the removal of on the ground 18 remaining residual dirt. From the final cleaning of the cleaned tray trolley 130 in the residual dirt clearing position 134 remain in the inventively proposed device for clearing and separating 10 proceeding process steps with regard to the promotion of the trays, their reloading and their expulsion and their subsequent separation in the separating device 32 unaffected.
