Definitions
- the invention relates to a method for sorting textile articles according to the preamble of claim 1 (see WO-A-03031291 ).
- Clothing, flat linen and other textile articles are sorted for different purposes.
- items of laundry washed in commercial laundries, in particular items of clothing are sorted according to their nature, the recipients and / or the order of delivery to customers.
- the laundry items accumulate in laundries in batches, always sorting the entire batch.
- the problem is sorting larger batches. Such batches can contain up to 1,000 items of laundry or other textile items.
- the sorting of such large batches has proven to be difficult, because the laundry items or the like are transported on transporting hangers hanging on oblique rails. This according to the principle of gravity promotion taking place the hanging on transporting objects is due to the friction between the hanger hooks of the transport bracket and the rails limited to up to 50 pieces of clothing per rail. If there are more carrying straps with garments hanging from them on a rail, they can no longer be moved by gravity feed. Therefore, it is not yet possible to sort complete larger batches with reasonable effort.
- a sorting device for sorting textile articles which has a plurality of storage paths.
- the batch of items to be sorted is first divided into sub-batches and there is a pre-sorting according to belonging to the respective sub-batch items.
- the batch size is limited to the number of storage lanes. Larger batches require a corresponding number of storage lanes.
- the invention is based on the object of providing methods for sorting textile articles, in particular items of clothing, whereby even large batches can be sorted completely.
- a method for achieving this object comprises the measures of claim 1. Due to the fact that the respective charge is first divided into partial batches and a pre-sorting of the items belonging to the respective partial batch is carried out, the quantity of items to be sorted in the storage lanes becomes smaller, as a result of which the storage lanes no longer have to pick up items despite large batches conditionally along the rail of each storage lane are further transportable by gravity. The natural limits of the absorption capacity of the storage lanes are not exceeded by the prior division of the batch in partial batches, which can be sorted by the inventive process objects even large batches. By sorting the articles by retracting several times into the storage lanes, the length and the number of storage lanes can be changed as required. For large batches, it is not necessary to have such a large number of storage lanes that the items can be sorted by a single entry into the respective storage lane. In particular, the storage tracks can be made shorter thereby.
- each partial batch contains only those items that must be present after sorting in the same. It can be done by a complete sorting of the items in the respective sub-batch. The result is that after sorting the items each partial batch by stacking the partial batches a total sorted batch arises. For this purpose, it is preferably provided that after the sorting of all partial batches these are strung together in a specific sequence, so that from the individual partial batches a total sorted batch arises.
- a preferred embodiment of the method provides that the partial batches are sorted at least partially in parallel. For example, all sub-batches successively go through a first sorting process and then every other sorting process. It is also conceivable to sort the partial batches simultaneously (in parallel) in parallel juxtaposed sorting devices for each partial batch. The sorted part batches are then slotted out of the individual sorting devices in the order that results in a total sorted batch.
- At least one presorting of the objects takes place before they are retracted for the last time in the presorted state into the storage path for final sorting.
- the at least one pre-sorting it is possible to sort a respective laundry batch, even if it has a relatively large number of articles, on the basis of the number of storage lanes and their length-taking algorithms by repeatedly passing through the storage lanes. If, due to the number of items in the batch, a one-time presorting is not sufficient, a corresponding pre-sorting procedure can be performed with a corresponding algorithm, followed by final sorting. According to this procedure, the sorting takes place in successive steps up to the final sorting.
- the sorting of the objects in several successive steps takes place with a suitable algorithm.
- the order in which the objects are to be sorted is first determined based on the data stored in each item of information. Accordingly, the items are at least fictitious numbered and sorted sequentially based on this numbering. The number of the respective item is divided by the number of memory tracks integer. After the resulting integer remainder of the objects are distributed to the storage lane, by each one storage lane is provided for the same remainder and in the respective storage lane objects with the same remainder and in a storage lane objects are retracted without rest. This is a pre-sorting.
- the presorted objects are then moved out of the storage lane, wherein the storage lanes are emptied successively, so that all objects the storage lane gradually into leave the presorted order.
- the presorted in a storage path objects are distributed to all memory lanes, in such a way that the numbers of objects that are not integer divisible by the number of memory lanes are rounded up, so that they are integer divisible by the number of memory lanes.
- the items are stored in the memory lane corresponding to the consecutive numbering of all memory lanes, the respective memory lane with the sequence number and all numbers, the simple and multiple addition of the Number of storage lanes corresponds, can be sorted.
- the items can be sorted into the storage path in their sequence, with the entire batch being sorted if the storage paths leave objects one after the other according to the numbering of the storage path.
- the sorted items are then ready to ship.
- each storage lane is formed of a plurality of juxtaposed, preferably parallel storage lane sections. This makes it possible to shorten the storage lanes. Therefore, each storage lane can accommodate a number of items that could not slip along the rail of a single longer storage lane.
- the storage path sections increase the total storage capacity of the storage path, wherein the storage path sections of each storage path represent a single storage path in terms of sorting.
- each storage lane being provided for articles with different sorting criteria, and objects of the storage lane sections of each storage lane being taken up with the same sorting criteria.
- the memory track sections of each memory track be merged, in particular at the beginning and at the end of each memory track section.
- the objects are first retracted into a storage path section of the respective storage path and only when this storage path section is full, the following items, which are intended for the same storage lane retracted into the next storage lane section.
- the objects are in the storage path sections of each storage lane in the intended order, wherein by successively emptying the storage lane sections the objects of all Memory track sections of the same memory lane in the desired order (consecutively) get.
- garments 10 hanging on transport bars are sorted.
- the garments 10 are symbolically represented by a circle with a number to illustrate the sorting process.
- the sorting will not be based on numbers, but due to other sorting criteria, such as type of garments, the customer who owns the laundry items and / or the order in which the garments are unloaded from a truck at the customer.
- the corresponding information is stored on suitable media associated with the garments 10. *** " The sort order is determined based on this data. This sequence, in the embodiment shown, corresponds to the consecutive numbers 1 to 64 associated with the garments 10 symbolized by circles.
- These 64 garments 10 present a batch which is sorted for delivery, for example by loading a truck for delivery of washed garments 10 in a corresponding sequence, which corresponds to the order in which the vehicle drives the customers.
- a batch has far more items of clothing 10 than the garments 10 indicated in the figures to illustrate the method.
- the invention makes it possible to sort a batch of about 1,000 items of clothing 10.
- the in the Fig. 1 to 3 The sorting system shown has a sorting device 11, a transport path 12 and a circumferential, endless collecting track 13.
- the sorting device 11 shown has four parallel storage trays 14. All storage trays 14 are the same length. In the storage lanes are inclined, preferably straight rails on which the transport bracket on which hang the garments 10, can slide down without drive.
- the preferably identically formed storage lanes 14 thereby constitute gravity conveyors.
- the sorting device 11 has a much larger number of storage trays 14. The number of storage trays 14 depends on how large the maximum batch to be sorted is. Up to 20 storage lanes 14 can be provided.
- the ready-for-clothing items 10 from, for example, a laundry are transported in unsorted order along the transport path 12 to the higher-lying input ends 15 of the storage lanes 14.
- the garments 10 are directed to the storage path 14 provided for the respective sorting criterion.
- the output ends 16 are located at the input ends 15 opposite, deeper ends of the storage lanes 14.
- From the output ends 16 of the storage lanes 14 enter the garments 10 with their transport brackets on the circumferential collection track 13.
- the garments hanging on transporting hangers 10 can be guided via a connecting track 17 to the beginning of the transporting track 12, whereby the garments 10 can be transported from the transporting track 12 back to the input ends 15 of the storage trays 14.
- the collecting track 13 is associated with a second connecting track 18, with which the garments 10 can be handed over after the end sorting with the transport straps to a lying behind the storage lanes 14 sections of the transport path 12. From here, the sorted garments 10 in a in the Fig. 3 shown holding loop 19, from where the garments 10 are loaded in the desired order, for example, in a truck, which then brings the garments 10 to the respective customers.
- the invention provides for sorting the garments 10 hanging on the transporting stirrups by repeated retraction into the storage trays 14. The garments thus pass through the storage path 14 of the sorting device 11 several times.
- At least one pre-sorting is initially performed. Between the individual sorting operations arrive all garments 10, preferably all garments 10 a batch, from the output ends 16 of the storage lanes 14 on the circumferential collection track 13, from where the garments 10th get back to the transport path 12 via the connecting web 17, which threads the garments 10 again targeted via the input ends 15 in one of the storage lanes 14.
- the sorting of the garments 10 in several passes through the sorting device 11, so at least one pre-sorting and the subsequent end sorting of the garments 10, is computer-controlled with a specific algorithm. This algorithm also determines how many passes the garments 10 of the respective lot through the sorter 11 require. In the embodiment shown, where 64 garments 11 with four parallel storage trays 14 are to be sorted, three passes are required, ie a two-fold presorting and a final sorting. Depending on the number of garments 10 of the batch to be sorted and the number of storage lanes 14 less than three or more than three passes may be required.
- the first presorting is in the Fig. 1 shown. Accordingly, in the transport direction 20 of the transport path 12 first storage lane 14 (in the Fig. 1 to 3 the right memory track 14) retracted, whose number according to the order of final sorting divided by the number of memory track 14, ie in the illustrated embodiment with only four memory lanes 14 divided by "4", gives a remainder of "1". For example, if the laundry 61 is divided by "4", then this gives 15 and the remainder "1". Accordingly, in the transport direction 20 subsequent second storage lane 14 garments 10 are retracted, the serial number divided by "4" results in a remainder of "2". In the third storage lane 14 only those items of clothing 10 are retracted, the rest of which is "3". In the last storage path 14 seen in the transport direction 20, garments 10 are retracted, which are evenly divisible by "4", that is, the remainder is "0".
- the garments 10 slide automatically with the hanging on the storage lanes 14 transport brackets on the storage lanes 14 to the output ends 16. After presorting according to the Fig. 1 The garments 10 of the storage lanes 14 are gradually introduced into the collection track 13. First of all Garments 10 of the first storage lane 14 of the collecting track 13 and then supplied all garments 10 of the second, third and finally the fourth storage lane 14. About the connecting web 17, the garments 10 are transported with their transport brackets back to the input ends 15 of the storage lanes 14. Then the garments 10 coming from the respective storage lane 14 are distributed to the four storage lanes 14. This is done according to the following algorithm:
- the numeral of the garment 10 is rounded up to a number divisible by "4".
- the garment 10 numbered “61” is rounded up by the number "3" to "64", which, divided by "4", gives the value "16”.
- All garments 10 which after the split in the manner described above give a value which is “1” and each value added by "4" and a multiple of "4", for example "5", "9” and “13” , are introduced into the first storage lane 14.
- Garments 10 whose number is rounded up with “2” to be divided by "4" in integer, and the numbers “2", “2” plus “4" and “2” and a multiple of "4", ie “6", "10” and “14” are sorted into the second memory track 14.
- clothing items 10 are used which after rounding their number by “1” and dividing by “4" have the value "3" and “3” plus “4" and a multiple thereof, which enter the third memory track 14 and Garments 10 which are integer divisible by "4" without rounding and then have the value "4" or a multiple thereof, which are sorted into the fourth storage lane 14.
- the garments are on the four storage lanes 14 in the in Fig. 2 shown order.
- the garments 10 are then again promoted to the collection track 13, again in turn all garments 10 from the first storage lane 14 and then all garments 10 each successive storage lane 14.
- the garments 10 are distributed from the first storage lane 14 on the four storage lanes 14. Due to the two presortings, this distribution can be such that of the total of sixteen garments 10 of the first storage lane 14 after the second presorting the four first Garments 10 each storage lane 14 result.
- the first four items of clothing 10 are fed to each storage lane 14 from the second presorting of the first storage lane 14 and the remaining items of clothing 10 are distributed to the second to fourth storage lanes 14.
- the items of clothing 10 from the second, the third and the fourth storage path of the second pre-sorting are moved. After the garments 10 of all four storage lanes 14 have been distributed to the four storage lanes 14, the final sorting has taken place. This shows the Fig. 3 ,
- first all garments 10 of the first storage lane 14 are introduced into the collection lane 13 and then all the lumps 10 of the subsequent second, third and fourth storage lanes 14. This brings all the clothing items 10 into the correct one Order in the Fig. 3 is symbolized by numbers. From the collecting track 13, the sorted items of clothing 10 reach the holding pattern 19 via the connecting line 18. The items of clothing 10 are gradually removed from the holding pattern 19 and, for example, loaded onto a truck.
- the Fig. 4 shows an embodiment of the invention, which differs from the previous embodiment only in that each of the four memory lanes 14 has two memory track sections 21, 22. In the embodiment of Fig. 4 these run parallel. This makes it possible to reduce the number of consecutively arranged garments 10 per storage track section 21, 22. This leads to large batches of up to 1,000 pieces of clothing 10 that on each storage track section 21, 22 only so many transporting hanger with garments hanging thereon 10 must be arranged one behind the other that they can all slide down by gravity on the inclined storage track sections 21, 22.
- the first half of the clothing pieces 10 on each storage path 14 are directed into the first storage path section 21 and the second half into the second storage path section 22.
- the removal of the clothing items 10 from the storage path sections 21 and 22 are in the same order of retraction.
- the garments 10 are first moved out of the storage path section 21 and then out of the storage path section 22, after which the garments 10 of the entire storage path 14 have the intended order, in the embodiment of Fig. 4 the sorted sequence is analogous to Fig. 3 ,
- the batch of garments is divided, for example, in two partial batches.
- the partial batches are first formed by sorting the first 500 items of clothing into a first portion batch and the second 500 items of clothing into the second portion batch.
- Each partial batch is then sorted by itself, in principle according to the previously in connection with the embodiment of Fig. 1 to 3 described algorithms, wherein the number of memory track 10 may be correspondingly larger than "4". If there are two parallel groups of storage lanes, the sorting of each partial lot can be parallel. It is also conceivable to use the same storage lanes to make the individual sorting operations with the partial batches alternately.
- a first pre-sorting then takes place first with the first partial charge and then with the second partial charge. Subsequently, the next pre-sorting of the first partial batch and then the second partial batch and finally the final sorting of the first partial batch and then the second partial batch.
- the partial batch which is not involved in the current sorting is temporarily stored in the collecting track, wherein, if appropriate, several collecting tracks can also be provided for this exemplary embodiment.

Description
Die Erfindung betrifft ein Verfahren zum Sortieren textiler Gegenstände gemäß dem Oberbegriff des Anspruchs 1 (siehe
Problematisch ist es, größere Chargen zu sortieren. Solche Chargen können bis zu 1.000 Wäschestücke oder andere textile Gegenstände aufweisen. Die Sortierung solcher großen Chargen hat sich bisher als schwierig erwiesen, weil die Wäschestücke oder dergleichen an Transportbügeln hängend an schrägen Schienen weitertransportiert werden. Dieser nach dem Prinzip der Schwerkraftförderung erfolgende Weitertransport der an Transportbügeln hängenden Gegenstände ist aufgrund der Reibung zwischen den Bügelhaken der Transportbügel und den Schienen beschränkt auf bis zu 50 Bekleidungsstücke pro Schiene. Befinden sich mehr Transportbügel mit daran hängenden Bekleidungsstücken auf einer Schiene, können diese durch eine Schwerkraftförderung nicht mehr weiterbewegt werden. Deswegen ist es bislang nicht möglich, komplette größere Chargen mit vertretbarem Aufwand zu sortieren.The problem is sorting larger batches. Such batches can contain up to 1,000 items of laundry or other textile items. The sorting of such large batches has proven to be difficult, because the laundry items or the like are transported on transporting hangers hanging on oblique rails. This according to the principle of gravity promotion taking place the hanging on transporting objects is due to the friction between the hanger hooks of the transport bracket and the rails limited to up to 50 pieces of clothing per rail.

Der Erfindung liegt nun die Aufgabe zugrunde, Verfahren zum Sortieren textiler Gegenstände, insbesondere Bekleidungsstücke, zu schaffen, womit auch große Chargen vollständig sortiert werden können.The invention is based on the object of providing methods for sorting textile articles, in particular items of clothing, whereby even large batches can be sorted completely.
Ein Verfahren zur Lösung dieser Aufgabe weist die Maßnahmen des Anspruchs 1 auf. Dadurch, dass die jeweilige Charge zunächst in Teilchargen geteilt wird und dabei eine Vorsortierung der zur jeweiligen Teilcharge gehörenden Gegenstände vorgenommen wird, wird die in den Speicherbahnen zu sortierende Menge der Gegenstände geringer, wodurch die Speicherbahnen trotz großer Chargen nicht mehr Gegenstände aufnehmen müssen, als physikalisch bedingt längs der Schiene jeder Speicherbahn durch Schwerkraftförderung weitertransportierbar sind. Die natürlichen Grenzen der Aufnahmekapazität der Speicherbahnen werden so durch die vorherige Aufteilung der Charge in Teilchargen nicht überschritten, wodurch nach dem erfindungsgemäßen Verfahren Gegenstände selbst großer Chargen sortiert werden können. Indem die Gegenstände durch mehrmaliges Einfahren in die Speicherbahnen sortiert werden, können die Länge und die Anzahl der Speicherbahnen den Anforderungen entsprechend verändert werden. Bei großen Chargen braucht keine so große Anzahl von Speicherbahnen vorhanden zu sein, dass durch einmaliges Einfahren in die jeweilige Speicherbahn die Gegenstände sortiert werden können. Insbesondere können die Speicherbahnen dadurch kürzer ausgebildet werden.A method for achieving this object comprises the measures of
Eine bevorzugte Weiterbildung des Verfahrens sieht es vor, dass jede Teilcharge nur solche Gegenstände enthält, die nach dem Sortieren in derselben vorhanden sein müssen. Es kann dadurch eine lückenlose Sortierung der Gegenstände in der jeweiligen Teilcharge erfolgen. Die Folge ist, dass nach dem Sortieren der Gegenstände jeder Teilcharge durch Aneinanderreihen der Teilchargen eine insgesamt sortierte Charge entsteht. Dazu ist es vorzugsweise vorgesehen, dass nach dem Sortieren aller Teilchargen diese in einer gezielten Aufeinanderfolge aneinandergereiht werden, so dass aus den einzeln Teilchargen eine insgesamt sortierte Charge entsteht.A preferred embodiment of the method provides that each partial batch contains only those items that must be present after sorting in the same. It can be done by a complete sorting of the items in the respective sub-batch. The result is that after sorting the items each partial batch by stacking the partial batches a total sorted batch arises. For this purpose, it is preferably provided that after the sorting of all partial batches these are strung together in a specific sequence, so that from the individual partial batches a total sorted batch arises.
Eine bevorzugte Ausgestaltung des Verfahrens sieht es vor, dass die Teilchargen mindestens teilweise parallel sortiert werden. Beispielsweise durchlaufen alle Teilchargen nacheinander einen ersten Sortiervorgang und dann jeden weiteren Sortiervorgang. Es ist auch denkbar, die Teilchargen gleichzeitig (parallel) zu sortieren in parallel nebeneinander angeordneten Sortiervorrichtungen fĂĽr jede Teilcharge. Die sortierten Teilchargen werden dann aus den einzelnen Sortiervorrichtungen in der Reihenfolge aufgeschleust, die eine insgesamt sortierte Charge ergibt.A preferred embodiment of the method provides that the partial batches are sorted at least partially in parallel. For example, all sub-batches successively go through a first sorting process and then every other sorting process. It is also conceivable to sort the partial batches simultaneously (in parallel) in parallel juxtaposed sorting devices for each partial batch. The sorted part batches are then slotted out of the individual sorting devices in the order that results in a total sorted batch.
Bevorzugt erfolgt mindestens eine Vorsortierung der Gegenstände, bevor diese im vorsortierten Zustand letztmalig in die Speicherbahn zum Endsortieren eingefahren werden. Infolge der mindestens einen Vorsortierung kann anhand von die Anzahl der Speicherbahnen und ihre Länge berücksichtigenden Algorithmen durch mehrmaliges Durchlaufen der Speicherbahnen eine jeweilige Wäschecharge, auch wenn diese eine relativ große Anzahl von Gegenständen aufweist, sortiert werden. Wenn aufgrund der Anzahl der Gegenstände der Charge eine einmalige Vorsortierung nicht ausreicht, kann mit einem entsprechenden Algorithmus eine mehrmalige Vorsortierung und anschließend die Endsortierung vorgenommen werden. Gemäß dieser Vorgehensweise erfolgt die Sortierung in aufeinanderfolgenden Schritten bis hin zur Endsortierung.Preferably, at least one presorting of the objects takes place before they are retracted for the last time in the presorted state into the storage path for final sorting. As a result of the at least one pre-sorting, it is possible to sort a respective laundry batch, even if it has a relatively large number of articles, on the basis of the number of storage lanes and their length-taking algorithms by repeatedly passing through the storage lanes. If, due to the number of items in the batch, a one-time presorting is not sufficient, a corresponding pre-sorting procedure can be performed with a corresponding algorithm, followed by final sorting. According to this procedure, the sorting takes place in successive steps up to the final sorting.
Die Sortierung der Gegenstände in mehreren aufeinanderfolgenden Schritten erfolgt mit einem geeigneten Algorithmus. Dazu wird zunächst anhand der Daten, die in jedem Gegenstand zugeordneten Informationsträgern abgespeichert sind, die Reihenfolge, wonach die Gegenstände sortiert werden sollen, festgelegt. Dementsprechend werden die Gegenstände zumindest fiktiv nummeriert und anhand dieser Nummerierung fortlaufend sortiert. Dabei wird die Nummer des jeweiligen Gegenstands durch die Anzahl der Speicherbahnen ganzzahlig geteilt. Nach dem sich dabei ergebenden ganzzahligen Rest werden die Gegenstände auf die Speicherbahn verteilt, indem jeweils eine Speicherbahn für den gleichen Rest vorgesehen ist und in die jeweilige Speicherbahn Gegenstände mit gleichem Rest und in eine Speicherbahn Gegenstände ohne Rest eingefahren werden. Dabei kommt eine Vorsortierung zustande. Die vorsortierten Gegenstände werden anschließend aus der Speicherbahn herausgefahren, wobei die Speicherbahnen nacheinander entleert werden, so dass alle Gegenstände die Speicherbahn nach und nach in der vorsortierten Reihenfolge verlassen. Anschließend werden die in einer Speicherbahn vorsortierten Gegenstände auf alle Speicherbahnen verteilt, und zwar so, dass die Nummern der Gegenstände, die nicht ganzzahlig durch die Anzahl der Speicherbahnen teilbar sind, aufgerundet werden, damit sie durch die Anzahl der Speicherbahnen ganzzahlig teilbar sind. Nachdem die gegebenenfalls aufgerundeten Nummern der Gegenstände durch die Anzahl der Speicherbahnen geteilt ist, werden die Gegenstände in diejenige Speicherbahn abgelegt, die der fortlaufenden Nummerierung aller Speicherbahnen entspricht, wobei die jeweilige Speicherbahn mit der laufenden Nummer und allen Nummern, die der einfachen und mehrfachen Hinzuaddierung der Anzahl der Speicherbahnen entspricht, einsortiert werden. Es sind dann in einem nächsten Speichervorgang die Gegenstände in ihrer Reihenfolge in die Speicherbahn einsortierbar, wobei die ganze Charge sortiert ist, wenn die Speicherbahnen Gegenstände nacheinander entsprechend der Nummerierung die Speicherbahn verlassen. Die sortierten Gegenstände sind dann versandbereit.The sorting of the objects in several successive steps takes place with a suitable algorithm. For this purpose, the order in which the objects are to be sorted is first determined based on the data stored in each item of information. Accordingly, the items are at least fictitious numbered and sorted sequentially based on this numbering. The number of the respective item is divided by the number of memory tracks integer. After the resulting integer remainder of the objects are distributed to the storage lane, by each one storage lane is provided for the same remainder and in the respective storage lane objects with the same remainder and in a storage lane objects are retracted without rest. This is a pre-sorting. The presorted objects are then moved out of the storage lane, wherein the storage lanes are emptied successively, so that all objects the storage lane gradually into leave the presorted order. Subsequently, the presorted in a storage path objects are distributed to all memory lanes, in such a way that the numbers of objects that are not integer divisible by the number of memory lanes are rounded up, so that they are integer divisible by the number of memory lanes. After the possibly rounded up numbers of the items is divided by the number of storage lanes, the items are stored in the memory lane corresponding to the consecutive numbering of all memory lanes, the respective memory lane with the sequence number and all numbers, the simple and multiple addition of the Number of storage lanes corresponds, can be sorted. Then, in a next storage process, the items can be sorted into the storage path in their sequence, with the entire batch being sorted if the storage paths leave objects one after the other according to the numbering of the storage path. The sorted items are then ready to ship.
Bei einer bevorzugten Weiterbildung des zuvor beschriebenen Verfahrens ist es vorgesehen, die Gegenstände in mehreren Speicherbahnen unterzubringen, wobei jede Speicherbahn aus mehreren nebeneinanderliegenden, vorzugsweise parallelen Speicherbahnabschnitten gebildet wird. Dadurch ist es möglich, die Speicherbahnen zu verkürzen. Deswegen kann jede Speicherbahn eine solche Anzahl von Gegenständen aufnehmen, die auf der Schiene einer einzelnen längeren Speicherbahn nicht entlangrutschen könnten. Durch die Speicherbahnabschnitte wird die Gesamtaufnahmekapazität der Speicherbahn vergrößert, wobei die Speicherbahnabschnitte jeder Speicherbahn sortiertechnisch eine einzige Speicherbahn darstellen.In a preferred embodiment of the method described above, it is provided to accommodate the objects in a plurality of storage lanes, wherein each storage lane is formed of a plurality of juxtaposed, preferably parallel storage lane sections. This makes it possible to shorten the storage lanes. Therefore, each storage lane can accommodate a number of items that could not slip along the rail of a single longer storage lane. The storage path sections increase the total storage capacity of the storage path, wherein the storage path sections of each storage path represent a single storage path in terms of sorting.
Bevorzugt ist es vorgesehen, alle Gegenstände einer Charge auf mehreren Speicherbahnen sortiert zu verteilen, wobei jede Speicherbahn für Gegenstände mit anderen Sortierkriterien vorgesehen wird und von den Speicherbahnabschnitten jeder Speicherbahn Gegenstände mit gleichen Sortierkriterien aufgenommen werden. Dazu ist es bevorzugt vorgesehen, dass die Speicherbahnabschnitte jeder Speicherbahn zusammengeführt werden, und zwar insbesondere am Anfang und am Ende jedes Speicherbahnabschnitts.It is preferably provided to distribute all articles of a batch sorted on several storage lanes, each storage lane being provided for articles with different sorting criteria, and objects of the storage lane sections of each storage lane being taken up with the same sorting criteria. For this purpose, it is preferably provided that the memory track sections of each memory track be merged, in particular at the beginning and at the end of each memory track section.
Gemäß einer bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens werden die Gegenstände zunächst in einen Speicherbahnabschnitt der jeweiligen Speicherbahn eingefahren und erst wenn dieser Speicherbahnabschnitt voll ist, die folgenden Gegenstände, die für die gleiche Speicherbahn bestimmt sind, in den nächsten Speicherbahnabschnitt eingefahren. Dadurch befinden sich die Gegenstände in den Speicherbahnabschnitten jeder Speicherbahn in der vorgesehenen Reihenfolge, wobei durch nacheinander erfolgendes Leeren der Speicherbahnabschnitte die Gegenstände von allen Speicherbahnabschnitten der gleichen Speicherbahn in die gewünschte Reihenfolge (hintereinander) gelangen.According to a preferred embodiment of the method according to the invention, the objects are first retracted into a storage path section of the respective storage path and only when this storage path section is full, the following items, which are intended for the same storage lane retracted into the next storage lane section. As a result, the objects are in the storage path sections of each storage lane in the intended order, wherein by successively emptying the storage lane sections the objects of all Memory track sections of the same memory lane in the desired order (consecutively) get.

Die Erfindung wird nachfolgend anhand der in den Figuren vereinfacht dargestellten Sortieranlagen erläutert. In den gezeigten Ausführungsbeispielen werden an Transportbügeln hängende Bekleidungsstücke 10 sortiert. Die Bekleidungsstücke 10 sind symbolisch dargestellt durch einen Kreis mit einer Nummer zur Verdeutlichung des Sortiervorgangs. In der Regel wird die Sortierung aber nicht anhand von Nummern erfolgen, sondern aufgrund anderer Sortierkriterien, beispielsweise Art der Wäschestücke, den Kunden, denen die Wäschestücke gehören und/oder die Reihenfolge, in der die Bekleidungsstücke aus einem Lkw beim Kunden entladen werden. Die entsprechenden Informationen sind auf geeigneten Datenträgern gespeichert, die den Bekleidungsstücken 10 zugeordnet sind. Anhand dieser Daten wird die Sortierreihenfolge festgelegt. Diese Reihenfolge entspricht im gezeigten Ausführungsbeispiel den den mit Kreisen symbolisierten Bekleidungsstücken 10 zugeordneten fortlaufenden Ziffern 1 bis 64. Diese 64 Bekleidungsstücke 10 stellen eine Charge da, die sortiert zur Auslieferung gelangt, indem beispielsweise ein Lkw zur Auslieferung gewaschener Bekleidungsstücke 10 in entsprechender Reihenfolge beladen wird, die der Reihenfolge entspricht, in der das Fahrzeug die Kunden anfährt. In der Praxis verfügt eine Charge über weitaus mehr Bekleidungsstücke 10 als die in den Figuren zur Verdeutlichung des Verfahrens angedeuteten Bekleidungsstücke 10. Die Erfindung ermöglicht es, eine Charge mit etwa 1.000 Bekleidungsstücken 10 zu sortieren.The invention will be explained below with reference to the sorting systems shown in simplified form in the figures. In the exemplary embodiments shown,
Die in den
Die versandbereiten Bekleidungsstücke 10 aus beispielsweise einer Wäscherei werden in unsortierter Reihenfolge längs der Transportbahn 12 zu den höherliegenden Eingangsenden 15 der Speicherbahnen 14 transportiert. Von der Transportbahn 12 werden die Bekleidungsstücke 10 auf die für das jeweilige Sortierkriterium vorgesehene Speicherbahn 14 geleitet. Durch die Speicherbahnen 14 rutschen die an Transportbügeln hängenden Bekleidungsstücke 10 selbsttätig (schwerkraftbedingt) zu den tieferliegenden Ausgangsenden 16. Die Ausgangsenden 16 befinden sich an den Eingangsenden 15 gegenüberliegenden, tieferliegenden Enden der Speicherbahnen 14. Von den Ausgangsenden 16 der Speicherbahnen 14 gelangen die Bekleidungsstücke 10 mit ihren Transportbügeln auf die umlaufende Sammelbahn 13. Diese hinsichtlich des Verlaufs in den
Die Erfindung sieht es vor, die an den Transportbügeln hängenden Bekleidungsstücke 10 durch mehrmaliges Einfahren in die Speicherbahnen 14 zu sortieren. Die Bekleidungsstücke durchlaufen dadurch die Speicherbahn 14 der Sortiereinrichtung 11 mehrfach.The invention provides for sorting the
Dazu wird zunächst mindestens eine Vorsortierung vorgenommen. Beim letzten Durchlauf der Speicherbahnen 14 erfolgt eine Endsortierung der Bekleidungsstücke 10. Zwischen den einzelnen Sortiervorgängen gelangen alle Bekleidungsstücke 10, und zwar vorzugsweise alle Bekleidungsstücke 10 einer Charge, von den Ausgangsenden 16 der Speicherbahnen 14 auf die umlaufende Sammelbahn 13, von wo aus die Bekleidungsstücke 10 über die Verbindungsbahn 17 wieder zur Transportbahn 12 gelangen, die die Bekleidungsstücke 10 erneut über die Eingangsenden 15 gezielt in eine der Speicherbahnen 14 einfädelt.For this purpose, at least one pre-sorting is initially performed. Between the individual sorting operations arrive all
Das Sortieren der Bekleidungsstücke 10 in mehreren Durchläufen durch die Sortiereinrichtung 11, also das mindestens einmalige Vorsortieren und das anschließende Endsortieren der Bekleidungsstücke 10, erfolgt rechnergesteuert mit einem bestimmten Algorithmus. Dieser Algorithmus legt auch fest, wie viele Durchläufe die Bekleidungsstücke 10 der jeweiligen Charge durch die Sortiereinrichtung 11 erfordern. Im gezeigten Ausführungsbeispiel, wo 64 Bekleidungsstücke 11 mit vier parallelen Speicherbahnen 14 zu sortieren sind, sind drei Durchläufe erforderlich, also ein zweimaliges Vorsortieren und ein Endsortieren. Je nach Anzahl der Bekleidungsstücke 10 der zu sortierenden Charge und die Anzahl der Speicherbahnen 14 können weniger als drei oder auch mehr als drei Durchläufe erforderlich sein.The sorting of the
Die erste Vorsortierung ist in der
Die Bekleidungsstücke 10 rutschen mit dem auf den Speicherbahnen 14 hängenden Transportbügeln selbsttätig auf den Speicherbahnen 14 zu den Ausgangsenden 16. Nach der Vorsortierung gemäß der
Es wird die Ziffer des Bekleidungsstücks 10 aufgerundet auf eine durch "4" teilbare Zahl. Beispielsweise wird das Bekleidungsstück 10 mit der Nummer "61" um die Zahl "3" aufgerundet auf "64", was durch "4" geteilt den Wert "16" ergibt. Alle Bekleidungsstücke 10, die in der vorstehend beschriebenen Weise nach der Teilung einen Wert ergeben, der "1" und jeweils um "4" und ein Mehrfaches von "4" hinzuaddierten Wert ist, beispielsweise "5", "9" und "13", werden in die erste Speicherbahn 14 eingeschleust. Bekleidungsstücke 10, deren Nummer mit "2" aufgerundet wird, um durch "4" ganzzahlig geteilt werden zu können, und die Zahl "2", "2" plus "4" und "2" und ein Mehrfaches von "4", also "6", "10" und "14" ergeben, werden in die zweite Speicherbahn 14 einsortiert. Genauso wird mit Bekleidungsstücken 10 verfahren, die nach dem Aufrunden ihrer Nummer um "1" und Teilen durch "4" den Wert "3" und "3" plus "4" und ein Mehrfaches hiervon haben, die in die dritte Speicherbahn 14 gelangen und Bekleidungsstücke 10, die ohne Aufzurunden ganzzahlig durch "4" teilbar sind und dann den Wert "4" oder ein Mehrfaches davon haben, die in die vierte Speicherbahn 14 einsortiert werden.The numeral of the
Nachdem alle Bekleidungsstücke 10 von der ersten Speicherbahn 14 der ersten Vorsortierung auf die vier Speicherbahnen 14 verteilt sind, werden dahin die Bekleidungsstücke 10 aus der zweiten, dann der dritten und schließlich der vierten Speicherbahn 14 aus der ersten Vorsortierung auf die Speicherbahnen 14 gleichmäßig verteilt.After all
Nach der zweiten Vorsortierung befinden sich die BekleidungsstĂĽcke auf den vier Speicherbahnen 14 in der in der
Infolge der beiden zuvor beschriebenen Vorsortierungen werden die BekleidungsstĂĽcke 10 aus der ersten Speicherbahn 14 verteilt auf die vier Speicherbahnen 14. Aufgrund der beiden Vorsortierungen kann diese Verteilung so erfolgen, dass von den insgesamt sechzehn BekleidungsstĂĽcken 10 der ersten Speicherbahn 14 nach der zweiten Vorsortierung die vier ersten BekleidungsstĂĽcke 10 jeder Speicherbahn 14 ergeben. Dabei werden die ersten vier BekleidungsstĂĽcke 10 jeder Speicherbahn 14 aus der zweiten Vorsortierung der ersten Speicherbahn 14 zugefĂĽhrt und die ĂĽbrigen BekleidungsstĂĽcke 10 auf die zweite bis vierte Speicherbahn 14 verteilt. Genauso wird mit den BekleidungsstĂĽcken 10 aus der zweiten, der dritten und der vierten Speicherbahn der zweiten Vorsortierung verfahren. Nachdem die BekleidungsstĂĽcke 10 aller vier Speicherbahnen 14 auf die vier Speicherbahnen 14 verteilt worden sind, ist die Endsortierung erfolgt. Dies zeigt die
Nachdem die Endsortierung der Bekleidungsstücke 10 in jeder Speicherbahn 14 erfolgt ist, werden zunächst alle Bekleidungsstücke 10 der ersten Speicherbahn 14 in die Sammelbahn 13 eingeschleust und anschließend alle Bekleidungsstücke 10 der nachfolgenden zweiten, dritten und vierten Speicherbahn 14. Dadurch gelangen alle Bekleidungsstücke 10 in die richtige Reihenfolge, die in der
Die
Bei der Teilung der jeweiligen Speicherbahn 14 in zwei Speicherbahnabschnitte 21, 22 wird die erste Hälfte der Bekleidungsstücke 10 auf jeder Speicherbahn 14 in den ersten Speicherbahnabschnitt 21 geleitet und die zweite Hälfte in den zweiten Speicherbahnabschnitt 22. Das Herausfahren der Bekleidungsstücke 10 aus den Speicherbahnabschnitten 21 und 22 erfolgt in der gleichen Reihenfolge des Einfahrens. Im gezeigten Ausführungsbeispiel werden die Bekleidungsstücke 10 erst aus dem Speicherbahnabschnitt 21 und dann aus dem Speicherbahnabschnitt 22 herausgefahren, wonach die Bekleidungsstücke 10 der gesamten Speicherbahn 14 die vorgesehene Reihenfolge aufweisen, und zwar im Ausführungsbeispiel der
Es ist ein nicht gezeigtes Ausführungsbeispiel der Erfindung denkbar, bei der die Charge der Bekleidungsstücke aufgeteilt wird, beispielsweise in zwei Teilchargen. Wenn beispielsweise 1.000 Bekleidungsstücke zu sortieren sind, werden zunächst die Teilchargen gebildet, durch Sortierung der ersten 500 Bekleidungsstücke in eine erste Teilcharge und die zweiten 500 Bekleidungsstücke in die zweite Teilcharge. Jede Teilcharge wird dann für sich sortiert, und zwar im Prinzip nach den zuvor im Zusammenhang mit dem Ausführungsbeispiel der
