A SYSTEM FOR DISPENSING OF GARMENTS
Field of the Invention
The present invention relates to a system for dis¬ pensing of at least one specific clean garment requested by an user. Said system comprises a loading unit, wherein the garments are loaded onto at least one stock conveyor at a predetermined position of the stock conveyor, a reading unit, which is adapted to read a RFID trans¬ ponder, preferably being incorporated in the garments. The system further comprises a control unit, which is adapted to control the location of the specific garments on the stock conveyor at a specific time, a display unit, wherein the user is requesting the garments and which is adapted to communicate with the control unit, and a dis¬ pensing unit, wherein the requested garments are dis- pensed to the user.
Background art
In the prior art dispensing systems according to the one mentioned by way of introduction is known, such as for instance in SE 507 475.
These systems are used in connection with dispensing of clean garments to an user and are often used in larger companies or facilities, wherein hygiene are of great im¬ portance or where the work performed often soils the clothes.
In the known systems the delivery of specific gar¬ ment to an user is carried out by the user identifies himself to the system and then requests a specific piece of garment. The system then processes the request by identifying the specific garment (or the type of garment)
on the stock conveyor and afterwards conveying said gar¬ ment to the dispensing unit. The chosen garment may be placed a great distance from the dispensing unit, where¬ fore it has to be conveyed this long distance to the dis- pensing unit, with the consequence that the user may ex¬ perience a long delivery time.
Furthermore, if more than one garment is chosen or requested by the user this may also extend the delivery time. The consequence is that the known systems often give a bottleneck for delivery due to too slow delivery, i.e. the far distances the specific garments may have to be conveyed before dispensing and can thereby create a queue of users at the system.
Thus, there is a great need for a system which may decrease the delivery time especially when a larger num¬ ber of user shall be processed substantially at the same time.
Summary of the Invention An object of the present invention is to signifi¬ cantly reduce the above disadvantages and drawbacks of the prior art. More specifically, it is an object to pro¬ vide a rapid system for dispensing clean garments to an user. It is also an object of the present invention to provide a system, which remembers the previous choice or use of garments of an user.
Another object of the present invention is to pro¬ vide a system, which enables a little time span for each user.
The above objects, together with numerous other ob¬ jects, advantages and features, which will become evident from the below description, are accomplished by a solu-
tion in accordance with the present invention by the sys¬ tem comprises a delivery conveyor, which is arranged be¬ tween the stock conveyor and the dispensing unit.
Hereby a fast and rapid dispensing system is ob- tained, which essentially decreases the delivery time of the garments. Furthermore, by using the inventive system it is obtained that more users may be handled using the same system. This is especially important where users ar¬ rives within the same working period for shift work. Due to the fact that this system is capable of dispensing garments to a large number of users in a short time this results in fewer systems for one customer, and an essen¬ tial decrease of costs for the companies .
The term "garments" is in this context to be con- strued as being clothes such as trousers, shirts, working coats, boiler suits etc. or flat linen such as linen, towels, bedclothes etc., but also helmets as well as shoes and boots.
In a preferred embodiment according to the inven- tion, the delivery conveyor may at least comprise one waiting position of the garment, one dispensing position of the garment and one empty position. During operation the requested garment is picked from the stock conveyor and placed at the waiting position on the delivery con- veyor. If the dispensing position is empty, the garment is immediately moved from the waiting position to the dispensing position. If the dispensing position is full, the garment on the waiting position stays ready for dis¬ pensing, i.e. being moved to the dispensing position, af- ter the garment at the dispensing position is removed.
When the garment is picked of at the dispensing position, the device which may hold or carry the specific garment, for instance a hanger, is moved to the empty position.
Hereinafter the system chooses the second piece of gar¬ ment on the stock conveyor and place this on the waiting position, which saves considerable time for the user, which requests the second choice of garment. If the gar- ment is not picked of at the dispensing position, the garments from both the dispensing position and the wait¬ ing position are moved back on the stock conveyor after a certain time.
In an expedient embodiment according to the inven- tion, the control unit may comprise a learning module, which is adapted to learn the requests of the users to a specific time so that the learning module controls, i.e. places, the requested garments to be near to the dispens¬ ing unit at a specific time. Hereby is a fast and rapid dispensing system obtained. The learning module of the invention enables that the choice or request of garments is positioned close to the dispensing unit. For instance, pooled garments of each garment-type may be distributed on the stock or delivery conveyor closest to the dispens- ing unit in a distribution depending of the usage of the garment, and personal garments may be moved to the stock or delivery conveyor closest to the dispensing unit at the time when the user normally arrives to pick up his or hers garments. This embodiment of the present invention acts as an accelerator of the dispensing of garments so that an essentially decrease of delivery time of garments is obtained.
According to the invention, the system may comprise a return unit for used or soiled garments, said return unit comprises a further reading unit, which is adapted to read the transponder incorporated in the garments . Hereby is obtained a closed loop system wherein the pro¬ vider of the system may have complete control of the
situation of the garments, i.e. what is dispensed and what is returned and by whom.
Advantageously the control unit may further comprise a storing unit, which is adapted to store the latest re- turn of soiled garments for a specific user. This storing unit according to the invention may communicate with the display unit so that information regarding the latest re¬ turn of the garments appears on the display unit when the user identify himself or herself to the system, whereby said user can approve the displayed information by one action, for instance by "one-touch" on the display, and thereby get the same garments dispensed as he or she re¬ turned. The matter is that the storing unit remembers the latest return of soiled garments for each user. This in- formation appears on the display after the user has iden¬ tified himself, and the user just has to approve this choice with one touch. This embodiment of the present in¬ vention acts as an accelerator of the dispensing of gar¬ ments so that an essentially decrease of delivery time of garments is obtained.
In a preferred embodiment according to the invention the conveyors may be ceiling mounted, so that the loaded garments are conveyed beneath the conveyors. This embodi¬ ment of the conveyor especially enables the possibility for placing the garments on hangers.
According to the invention the RFID transponder, i.e. radio frequency identification, may comprise infor¬ mation regarding the specific garment such as size, spe¬ cific user, etc.

Description of Preferred Embodiments In Fig. 1 the system 1 according to invention is shown schematically. The system 1 comprises a loading unit 2, wherein the garments (not shown) are loaded onto at least one stock conveyor 3 at a predetermined position of the stock conveyor 3. In this embodiment there is only shown one stock conveyor 3, however, a plurality of stock conveyors may be arranged in connection with each other depending on the capacity of the system.
A reading unit 4 is furthermore arranged in the sys¬ tem, said reading unit 4 is adapted to read a RFID trans- ponder (not shown) preferably incorporated in the gar¬ ments. Within the inventive idea the RFID transponder may also be located on a hanger whereupon the garments may be placed or even on the conveyor. After having read the
RFID transponder the reading unit 4 is submitting the in¬ formation to a control unit 5.
On basis of the information submitted from the read¬ ing unit 4 the control unit 5 is adapted to store the location of the specific garments on the stock conveyor 3 at a specific time and thereby control said stock con¬ veyor.
A display unit 6 is also arranged in the system 1. At this display unit 6, the user may request or chose the garments and which is adapted to communicate with the control unit 5. In connection with display unit 6 a card reader may be arranged, whereby the user may identify himself by using their personal card. The display unit 6 may within the inventive idea be a finger-touch screen. Additionally, the system comprises a dispensing unit 7, wherein the requested garments may be dispensed to the user.
According to the present invention the system com¬ prises a further delivery conveyor 8, which is arranged between the stock conveyor 3 and the dispensing unit 7. The delivery conveyor 8 will be described in detail in connection with Figs. 2-5.
According to a preferred embodiment of the invention the control unit 5 may comprise a learning module 9. This learning module 9 is adapted to learn the previous re¬ quests or choices of the users to a specific time so that the learning module 9 controls, i.e. places, the re¬ quested garments to be near to the dispensing unit 7 at a specific time. Hereby is obtained, that the learning module 9 and thereby the system 1 learns and remembers the users preferred choices of garments as well as at what time the specific user normally is picking up his or hers garment. On basis of this information the system
places the garments, which it knows the user normally will request in the near vicinity of the delivery con¬ veyor 8 or even on said conveyor. Thus, the delivery time for a specific user, who have used the system before or who's specific data have been stored in the control unit, will experience a fast and rapid delivery of garments.
Furthermore, the learning unit 6 may over a time pe¬ riod learn the habits of the specific user, i.e. the choices of garments as well as at what time the user nor- mally is collecting the garments so that the system will keep the garments in the vicinity of the dispensing unit 7 in a specific time interval.
According to another embodiment of the invention the system 1 may comprise a return unit 10 for used or soiled garments. Hereinafter, the soiled and used garments may be transported to a laundry for being cleaned and washed.
The return unit 10 comprises a further reading unit 11, which is adapted to read the transponder incorporated in the garments. Said reading unit 11 is adapted to sub- mit the read information to a storing unit 12, which ad¬ vantageously may be a part of the control unit 5. The storing unit 12 is adapted to store the latest return of the soiled garments for a specific user.
In a preferred embodiment of the invention the stor- ing unit 12 communicates with the display unit 6 so that information regarding the latest return of the garments appears on the display unit 6 when the user identify him¬ self or herself to the system 1. Hereby the user may ap¬ prove the displayed information by one action only, for instance a one-touch on a finger-touch screen, and thereby get the same garments dispensed as he or she re¬ turned. Hereby, the user of the system will experience an easy and simple way to choose and request garments, which
method at same time have decreased the delivery time es¬ sentially.
In Fig. 2 one embodiment of the delivery conveyor 8 of the invention is shown in a side view. In this embodi- ment the conveyor 8 is ceiling mounted so that the loaded garments are conveyed beneath the conveyors, for instance on hangers . Within the inventive idea the conveyors may also be belt conveyors which are mounted at the floor, whereby the garments are placed above or on the conveyor. In Fig. 3 the delivery conveyor 8 is shown in a top view. In this embodiment one waiting position 14 of the garment, one dispensing position 15 of the garment and one empty position 16 is shown. In connection with this embodiment a hanger magazine (not shown) may be arranged in connection with the empty position 16 of the delivery conveyor 8. At the hanger magazine the empty hangers 13 are collected in a magazine for return to the laundry.
