APPARATUS FOR RECEIVING ARTICLES, STORING THEM AFTER PROCESSING AND SUBSEQUENTLY RE-ISSUING THEM AND A METHOD OF OPERATING SUCH APPARATUS

Abstract: Carrying devices (11) carrying processed articles are stored at coded processed-article storage locations (10) and unloaded article carriers are stored at unloaded-carrier storage locations (13). A customer's token is scanned and an unloaded article carrier is taken from its storage location (13) and delivered to him by transport means (18 to 20), he arranges for his article for processing to be carried away by the article carrier and a computer records a newly created relationship between his token and the article carrier. After processing, his article is stored at a selected processed-article storage location (10) and a computer records a newly created relationship between his token and the selected storage location. When the customer re-presents his token, the processed article is taken from the selected storage location and delivered to the customer by the transport means (18 to 20). Before the unloaded article carrier is taken from its unloaded-­ carrier storage location (13), the computer may record a newly created relationship between the article carrier and the storage location.

Description: It is already known to provide apparatus for use in conjunction with processing establishments, such as laundries and dry-cleaning works, or in conjunction with collection and distribution centres for such establishments, whereby a customer can deposit articles to be processed, for example garments to be laundered, at a time when the processing establishment or collection and distribution centre is closed and no attendant is present, and can later collect the articles after processing of them, again when the processing establishment or collection and distribution centre is closed and no attendant is present; for example see United Kingdom Patent Specifications Nos. 1107988, 1317306, 1423135, 1604040 and 2080264. It is common for there to be N article-storage locations in the apparatus to receive articles from N or fewer customers, so that each customer has allocated to him one or more specific article-storage locations, to receive carriers destined to receive articles to be processed from that customer only and later to receive processed articles awaiting collection by that customer only. The result is that, at any one time, at many of the article-storage locations there are merely carriers awaiting use and, for dealing with a certain number of customers, there must be more storage locations, and the apparatus must in consequence be larger and more expensive, than is necessitated by the number of articles received for processing. It is also common for there to be N article carriers to receive articles from N or fewer customers, so that each customer has allocated to him one or more specific article carriers, to receive articles to be processed from that customer only, before transfer of the articles with the carrier or carriers to the processing point, and/or to receive processed articles awaiting collection by that customer only before transfer of the articles with the article carrier or carriers to a re-issue location. The result is that at any one time many of the article carriers are not in use and in consequence more of them must be provided than is necessitated by the number of articles received for processing. United Kingdom Patent Specification No. 2080264 discloses several forms of apparatus in which articles are received, stored after processing and subsequently re-issued, the apparatus comprising a reception location, a reissue location, a number of unloaded-carrier storage locations, a number of article carriers, a number of processed-article storage locations, transport means for transporting the articles and control means whereby when a customer presents a suitable information-bearing device this is automatically scanned and a suitable unloaded article carrier is automatically taken from an unloaded-carrier storage location by the transport means and delivered to the reception location at which the customer may arrange for his article or articles to be carried by the article carrier before it is automatically carried away by the transport means, and information relating his information-bearing device to the article carrier is automatically stored, and, after his article or articles has or have been processed and after it or they has or have been delivered to storage means selected from the processed-article storage locations, the article or articles is or are automatically delivered by the transport means to the re-issue location, at which the customer may retrieve it or them, when a suitable information-bearing device is presented. In a form of such apparatus described as prior art in Specification No. 2080264 the processed-article storage locations serve also as unloaded-carrier storage locations and the customer uses either a "standard card" or a "specific golden key card". Each such card is preallocated a storage location, which is always the same for that card, and so numerous storage locations are unused for long periods. In the form of such apparatus described in Specification No. 2080264 in relation to Figures 7 and 8, again the processed-article storage locations serve also as unloaded-carrier storage locations but here the apparatus may be operated by a standard card (which is not returned to the customer when his processed articles are collected by him) or a "specific golden key card" (which is so returned) or a "random golden key card" (which is so returned). The random golden key card is not initially associated with any particular storage location but when the customer presents it to a card reader in attempting to deposit articles for processing, the apparatus finds a storage location that is vacant, i.e. neither permanently allocated to a "standard card" or a "specific golden key card" nor temporarily allocated to another "random golden key card", and then correlates the number of that storage location with the number of the "random golden key card", whereupon that storage location is temporarily allocated to that card and remains so allocated until the customer's articles have been processed and delivered to him. Whilst such apparatus can considerably reduce the number of storage locations which are required, especially if not many "specific golden key cards" are issued, it remains a disadvantage that each storage location is allocated to a particular customer, and cannot be used by any other person, at least for the whole of the time between his depositing the articles for processing and his collecting the processed articles, including the often long time when the articles are at, or on the way to or from, the plant where the processing occurs. It is an object of the invention to reduce still further the number of storage locations which are required. According to a first aspect of the invention, there is provided apparatus as defined in claim 1. According to a second aspect of the invention, there is provided apparatus as defined in claim 2. The apparatus may be constructed to receive, for example, articles, for example garments, for dry-cleaning and/or articles for laundering and/or articles, for example shoes, for repair or other processing, for example films for developing and printing. The re-issue location may be also the reception location and the information-bearing device which is used to retrieve the processed article or articles may be the same information-bearing device as is used to obtain the unloaded article carrier and it may be scanned for retrieval of the article or articles by the same scanning means as is used to scan it on initially depositing the article or articles for processing. Preferably, the apparatus is constructed to respond to any one of a range of information-bearing devices including credit cards such as "Access", "Visa", "American Express" which are registered Trade Marks or Service Marks, etc., and preferably also including credit cards or tokens issued by the owners of the apparatus or by the dry-cleaners and/or launderers or other processors of the articles. In contrast to all the forms of apparatus disclosed in Specification No. 2080264, in the apparatus according to the first and second aspects of the present invention, the processed-article storage locations, which may for example be rings on which wire clothes hangers are suspended, do not serve also as unloaded-carrier storage locations; the latter may, for example, be tubes. The article carriers are preferably bags and/or boxes. According to third and fourth aspects of the invention, there is provided a method according to claim 5 and a method according to claim 10, respectively. Examples in accordance with the invention are described below with reference to the accompanying drawings, in which:- Figures 1A, 1B, 1C and 1D show diagrammatic plan views of four possible arrangements of part of an apparatus for receiving from a customer articles for processing, storing them after processing and returning them from store to the customer, Figure 2 shows a perspective view of storage means in the apparatus, Figure 3 shows a view of part of the storage means, as seen when looking in the direction of the arrow III in Figure 2, Figure 4 shows a detail of Figure 3, and Figure 5 shows another part of the storage means, as seen when looking in the direction of the arrow V in Figure 2. Each of the arrangements shown in Figures 1A, 1B, 1C and 1D includes a part 1 containing control equipment to which a service engineer has access when a door 2 is opened. On the side of the part 1 at which the door 2 is situated there is a slot into which a customer can insert an information-bearing device which identifies him, prior to depositing at part 3 of the apparatus, at its front, i.e. at the side thereof which is shown lowermost in each of Figures 1A, 1B, 1C and 1D, articles to be processed, for example garments to be dry-cleaned. Subsequently, after processing of the articles, he may insert the same information-bearing device or another information-bearing device in the same or another slot at the part 1 and retrieve his articles from the front of the same part 3 of the apparatus. The part 3 of the apparatus has a door 3A which automatically slides to the left, as indicated by the arrows, to permit articles to be inserted into or taken from the part 3 and which automatically slides to the right subsequently. The part 3 has doors 4 communicating with a storage zone 5 in which there are two parallel rails 6 from which cleaned articles 7 are suspended. Figures 1A and 1B show these parts 1 to 6 on the left side and on the right side, respectively, of a wall 8, with the door 2 in each case near the wall 8, whereas Figures 1C and 1D show the parts 1 to 6 on opposite sides of a wall 8 but here the part 1 is brought forward with respect to the remainder of the apparatus and its door 2 is on its side which is furthest from the wall 8. The parts 1 and 3 are two separate metal-framed compartments which can be installed in a variety of relative positions to best suit the requirements at the site. Referring now to Figures 2 and 3, each rail 6 provides a number of storage locations for cleaned articles. Each storage location is afforded by a ring 10 supported by a carrier 9, made of wire, which is received in a respective slot in the rail, the rings 10 being capable of receiving the hooks on conventional wire clothes hangers 11, as shown in Figure 4 of United Kingdom Patent Specification No. 2080264. Beside each storage location is a unique bar code identifying that storage location. Above one of the rails 6 there are a number of tubes 13 arranged in three rows for receiving rolled-up empty bags (referred to below as "deposit bags") with devices 14, e.g. handles, shown in Figure 4, on the bags which are engaged by a pick-off device when bags are to be withdrawn from the tubes. The tubes rest on shelves 13A on which there are bar codes 13B designating the different storage locations for empty bags. Above the other rail 6 there are rows of parcel bags or boxes 15 on shelves 15C, the bags or boxes having handles 15A, to be engaged by a pick-off device, when the bags or boxes are to be removed from compartments 15B formed by the shelves 15C and partitions 15D. The shelves 15C are formed with notches 15E which receive the handles 15A and the shelves have bar codes 15F in the notches to identify the storage locations for the bags or boxes 15. Above a central walkway 16 between the rails 6 there is a gantry 17 which can be moved to and fro along a line parallel to the rails 6. Suspended from the gantry 17 is a pick-off mechanism which includes a part 18 which can be turned about a vertical axis and an arm 19 which is attached to the rotatable part 18 and carries at opposite ends two pick-off devices 20 and 21, which can be moved in both directions parallel to the arm 19. The pick-off device 20 is so constructed that it can be used to pull a bag from a selected one of the tubes 13, or a bag or box from one of the shelves 15C, and the pick-off device 21 is so constructed, for example as shown in Figure 4 of Specification No. 2080264, that it can pick off a selected hanger 11, carrying cleaned garments surrounded by a polythene cover bag 22, from a selected one of the rails 6. For this purpose, the parts 18 to 21 can be raised and lowered as required. The picked-off bag, box or hanger is conveyed by the gantry into the part 3 of the apparatus. As the gantry approaches, the doors 4 automatically open to admit it to the part 3 and the doors 4 then close and remain closed, with the gantry in the part 3, until the gantry is about to return from the part 3 to the storage zone 5. The door 3A can be open only when the doors 4 are closed. As Figure 3 shows, there are groups of storage locations, on rails 6, assigned to receive small, medium and large articles or groups of articles. If desired, there could be two or more rails 6 above one another, especially in a part of the apparatus destined to receive short articles. The deposit bags have zip fasteners at their fronts and there are far more of them than there are tubes 13 to contain them, for example 500 deposit bags to 100 tubes 13. There are a number of possible methods in which the apparatus described can be used in conjunction with a computer. METHOD A 1. Before a customer arrives an operative has already put empty deposit bags, with bar-coded tags on them, at randomly chosen vacant bag storage locations, i.e. in empty tubes 13, and on each occasion he has scanned a bar code on or beside the tube in question and the bar code of the bag tag and the computer has recorded the signal so obtained so that it "knows" which bag tag is at which storage location and which storage locations are vacant. 2. A customer arrives and inserts a credit card, a card reader in the apparatus inspects it and, if it finds it satisfactory, instructs the customer to key in his telephone number, at a first keypad at the front of the part 1, near the above-mentioned slot, which he does, and then he presses an "enter" button. On a second keypad, he inserts, when instructed by the apparatus, details of articles being deposited for dry-cleaning. This may, for example, involve pressing twice a button marked "trousers" and once a button marked "dress", if he has two pairs of trousers and one dress to be cleaned. He also looks at a display of individual prices charged and of the total charge and presses a "total" button if satisfied or a "cancel" button if not. The computer prepares a printed record of the transaction, which is issued to the customer, and determines from the list of articles an appropriate bag size. A suitable bag is pulled out of its tube 13 and delivered to the customer by the gantry at part 3 of the apparatus. 3. The computer records the credit card number, the number of the empty bag storage location (tube 13) from which the bag was taken and the (different) bag tag number. An operative can now immediately put another empty bag, with another bag tag on it, in the same storage location, ready to be used by another customer. 4. When the first bag arrives at the part 3 of the apparatus, the door 3A opens and the first customer puts the articles to be cleaned into the bag and closes the bag with the zip fastener and the door 3A closes and the bag is automatically taken away by the gantry to a soiled articles storage area, for example the floor of the storage zone 5. The printed record is issued to the customer before the door 3A closes. 5. Each article is then marked to identify it with the number of the bar-coded tag on the bag from which it was taken and the bag tag is detached from the bag. The bag then has a fresh tag applied to it and it is rolled up and inserted in an empty tube 13. 6. The marked articles taken from the bags are periodically taken away manually, cleaned and then returned to the illustrated apparatus, with the bag tag numbers still on them and the bag tags themselves travel with them, since each of them is attached after the cleaning process to the article or one of the articles associated with that bag tag. 7. The articles are checked against a printed record of the contents of the bags both before cleaning them and after their return to the illustrated apparatus after cleaning. An operative decides which of a number of vacant cleaned-article storage locations (on the rails 6) is to receive the article or articles bearing one bag tag number, the choice of storage location being to some extent random but always to best suit the articles to be stored, and he uses a sensor to scan the bag tag number on the bag tag and the bar code associated with the selected cleaned-article storage location and the computer then "knows" that the article or articles has or have been returned and it stores the information relating the bag tag number to the storage location bar code. The bar coded bag tag is then no longer needed for the transaction in question and it is eventually used again for another customer or the same customer. The computer records the cleaned-article storage location in association with the bag tag number and credit card number and this information is printed. Then the information about the bag tag number is erased from the computer so that it therefore only records the credit card number in relation to the cleaned article storage location. 8. Upon re-presentation of the credit card, the cleaned article or articles is or are picked off from the appropriate one of the rails 6 and returned by the gantry to the part 3 of the apparatus, where the customer can receive it or them and take it or them away. This is the end of METHOD A When the empty bags, with bag tags attached to them, are inserted in vacant tubes 13, the operator could, on each occasion, scan the tube number and then the bag tag number, using a pen-type bar code scanner linked directly or indirectly to the memory of the computer. A similar scanner is used for each scanning operation. The computer is programmed to reject signals resulting from incomplete codes. If the articles originally deposited by the customer are too numerous to be accommodated at a single cleaned-article storage location, they may be stored at two or more such locations, in which case by appropriate scanning of the storage location numbers and of the bag tag numbers on the bag tags, there will be provided for the computer an indication of the appropriate storage location numbers. The computer has at all times a record of what tubes 13 are vacant and at what cleaned-article storage locations there are cleaned articles awaiting collection, also the numbers of the credit cards of their owners. If a customer comes for his articles before they are ready for collection, the computer can at once inform him that they are not ready, without instructing the pick-off mechanism to try to remove the cleaned articles from the rails 6. METHOD B Empty deposit bags are bar-coded, either directly or by having bar-coded tags attached to them, or code transmitters are attached to them. When they are inserted in the tubes 13 they are not scanned but information about which tubes 13 contain bags is given to and recorded at the computer. The steps of METHOD A, part 2 are performed, the bag called for by the customer being taken from the next tube in a pre-set sequence of the tubes. The steps of METHOD A, part 4 are performed. Each bag on its way to, at, or on its way from the part 3 of the apparatus is automatically scanned by a scanner, or the customer uses a pen-type bar scanner to scan it, and in either case there are transmitted to the computer the bag number and the number of the customer's credit card, which are correlated at the computer. After arrival of the bag in the storage zone 5, the steps of METHOD A, parts 5 to 8 are performed if bag tags are employed and analogous steps are performed if bag tags are not employed. METHOD C Bags are taken from the tubes 13, which do not have to be numbered, in predetermined sequence and at that stage the bags are not numbered, although they do bear an indication of the identity of the apparatus from which they come. The steps of METHOD A, parts 2 and 4 are performed and shortly before an empty bag arrives at the part 3 of the apparatus, or whilst the bag is there, the computer assigns a bag number to it. The computer records the bag number and the credit card number and prints and issues to the customer not the printed record mentioned above but a receipt, in duplicate, for the articles recorded by the customer as having been put in the bag, the receipt bearing the assigned bag number, and the customer is required to put one of the two copies of the receipt in the bag, whereby the customer applies the bag number to the bag, before the bag is automatically carried away. Thereafter steps analogous to METHOD A, parts 5 to 8 are performed. In all three methods there is no correlation, prior to the articles being returned to the apparatus after cleaning, between the customer's credit card number and the cleaned-article storage location or locations at which his cleaned article or articles is or are stored. This correlation is set up only when his article or articles is or are allotted a cleaned-article storage location or two or more such locations and it ceases to exist when he has collected his cleaned article or articles. METHODS A, B and C have been described in relation to dry-cleaning only, for simplicity, but in addition to, or instead of, articles for dry-cleaning, a customer could deposit articles for laundering and/or articles, for example shoes, for repair or other processing. Articles which have been laundered could be stored on hangers on the rails 6, or on similar rails, and shoes which have been repaired could be stored in the bags or boxes 15. It is possible for the storage arrangement on each side of the central walkway 16 to be divided into a number of bays, for example bay 1 being what is shown in Figure 3, bay 2 being to the right of it, bay 3 being to the right of that and so on. It is possible for there to be in each bay two, three or more tiers of article-storage means, for example a lower rail 6, a middle rail 6 directly above it and an upper rail 6 directly above that, with suitable spaces between the rails so that garments may be hung from them. Upon a customer returning to the apparatus to collect his article or articles, a main computer could check the customer's credit card number against its memory of assigned article-storage positions and instruct a microprocessor which operates the gantry as to the sequence of operations necessary to retrieve the required article or articles. If, for example, there were only one article to be retrieved, this one hanging from the central rail in bay 2 of a three-tier storage arrangement, the gantry could proceed in a direction parallel to the rails 6 until it reaches a vertical rail adjacent to bay 2. Then the gantry would stop and the pick-off mechanism carried by it would engage a vertical guide member and descend to the required level. Once this level was reached, as sensed by sensors carried by the pick-off mechanism, the pick-off mechanism would disengage from the vertical guide member and engage a horizontal guide rail and then the gantry would proceed, again in a direction parallel to the rails 6, along the bay 2 until the pick-off sensors command it to slow and eventually stop at the required position. During the final stage of its travel, the pick-off mechanism could be turned if necessary by rotation of the part 18. When the required pick-off device is in the appropriate position, it is displaced to the left or to the right (considering Figure 2) to pick-off the required clothes hanger or box. If the customer's credit card number has been correlated to two or more article-storage positions, for example one for dry-cleaned articles, one for laundered articles and another for a pair of shoes which have been repaired, the apparatus could be instructed to select the shortest item first and when the pick-off device 20 or 21 has withdrawn with it to its rest position (shown in Figure 2) the part 18 could be rotated to deliver the picked-off item onto an order accumulation rail carried by the gantry. Then in a similar way the next shortest item could be picked-off and put on the order accumulation rail carried by the gantry and finally the longest item and only then will the gantry be displaced to the part 3 of the apparatus In a case where the illustrated apparatus is located within a dry-cleaning establishment, it may be desirable to extend the storage rails 6 into the dry-cleaning establishment and have there a second location at which articles to be processed can be deposited and/or from which processed articles can be collected, so that customers who prefer to deposit and/or collect articles during normal business hours and to deal with the staff there, rather than with automatic apparatus, can do so at the same time as other customers are depositing and/or collecting articles at the apparatus which is shown in the drawings. Then there could be a second gantry to serve the second deposit and/or re-issue location.
