Definitions

  • the invention relates to the field of shoe handling and washing systems, in particular for use at locations where a high level of hygiene or cleanliness is required, for example operating rooms of hospitals or clean rooms.
  • a disadvantage here is that the entire process is laborious, time-consuming and costly. Not only the transportation requires a lot of time, also multiple manual manipulations of the shoes are necessary, including sorting them out by the pair and correct size, and placing them in the shoe cabinets. Furthermore it is not possible to perform a disinfection step in the tumbler washing machines.
  • washing machines only offer space for washing a truly limited number of for example five pairs of shoes at a time. Furthermore the entire handling and washing process still is laborious, time-consuming and costly.
  • JP-H-11244218 shows a shoe washing apparatus which can wash large numbers of shoes continuously.
  • the apparatus comprises a conveying track that extends substantially horizontally and along which shoe holding units can be transported.
  • a number of treatment units are provided.
  • a preliminary washing unit, a washing unit, a rinsing unit, a dehydration unit and a drying unit are provided.
  • the shoes can be thoroughly cleaned and dried afterwards.
  • a disadvantage with this known apparatus is that it requires a large floor space, making it unattractive to be used in for example a hospital. Furthermore it is disadvantageous that the apparatus is expensive to manufacture.
  • KR20030086121 shows an automatic shoe cleaning apparatus in which a lower horizontal band conveyor is provided that is placed in its entirety inside a big bathtub that is filled with washing liquid. Directly above the band conveyor a number of rotating brushes is provided. Shoes placed on top of the band conveyor can be transported from left to right through the bathtub while getting brushed clean. In order to prevent the shoes from floating upwards, an upper horizontal band conveyor is provided that has downwardly extending arms for keeping the shoes pushed downwards against the band conveyor surface during their movement along the brushes from left to right. For this the driving of the upper and lower band conveyors needs to be accurately tuned.
  • a disadvantage here is that the apparatus is difficult and expensive to manufacture. Furthermore shoes still need to be transported towards the apparatus, which together with the sorting of the shoes makes it laborious. It is difficult to load shoes between the arms and the lower band conveyor. During loading and unloading of the shoes, washing liquid is likely to escape from the bathtub.
  • JP 2000-139811 shows a footwear washing machine according to the preamble of claim 1.
  • This known machine comprises an upright positioned endless loop conveyor track along which shoe racks get moved. Along a lower part of the track a washing space is provided. Along an upper part of the track a drying space is provided. Between those spaces an opening-and-closing opening/mouth is provided along the track.
  • a disadvantage here is that the logistics and handling of the shoes is still laborious, time-consuming and costly. After being used the shoes need to collected at the work floor, from where they are transported towards the footwear washing machine. There they get placed by a dedicated operator in the racks of the washing machine. In order for the operator to be able to do this as quickly as possible, the opening-and closing opening/mouth is dimensioned such large that about twelve shoe racks at a same time can be loaded with shoes, six racks at a left and six racks at a right side of the track. As soon as all those twelve racks have been loaded, the operator has the conveyor move new sets of empty racks in front of the opening/mouth. As soon as the entire machine is thus loaded with shoes, the operator can press a start button for starting a washing cycle.
  • the shoes After having been washed and dried in the footwear washing machine, the shoes need to be taken out of the machine, and get transported back to the work floor where they can be used again.
  • the shoes In for example a hospital the shoes, after having been washed in a professional laundry or in an internal laundry department of the hospital, then are transported back to the work floor where they are manually placed and stored in shoe cabinets such that the personnel can take out their correct size at any desired moment.
  • the shoes then need to be sorted out by the pair unless they have been kept united during the entire transportation and washing steps. Regardless of this, the entire process requires a lot of transportation time, and also needs multiple manual manipulations of the shoes, including sorting or keeping them by the pair and correct size, and placing them in the shoe cabinets.
  • the present invention aims to overcome those disadvantages at least partly or to provide a useful alternative solution.
  • it aims to provide a compact and economic shoe handling and washing system that can be easily placed at a work floor such that users themselves can place their pair of shoes directly into the system for getting washed.
  • the system comprises a plurality of shoe carrier elements, a conveyor for moving the plurality of shoe carrier elements along a track, at least one loading and/or unloading station arranged next to the track for loading shoes to and/or unloading shoes from the shoe carrier elements, and a washing unit positioned next to the track.
  • the washing unit comprises a bowl that is fillable with a cleaning liquid.
  • the track is an endless loop with vertical leg sections connected to each other by an upper and lower bend section, wherein the bowl is positioned at the lower bend section such that shoes that are carried by the shoe carrier elements get moved through the bowl by movement of the shoe carrier elements along the lower bend section.
  • a housing is provided which covers at least a front side of the system. Preferably the entire system gets covered by the housing for forming a protective cabinet around it. In the housing an inlet and/or outlet opening is provided at the loading and/or unloading station.
  • a door is provided in the housing at the inlet and/or outlet opening, which door is movable between an open and closed position.
  • a respective one of the shoe carrier elements is accessible through the inlet and/or outlet opening for a user when the conveyor has stopped the shoe carrier elements from moving along the track.
  • a control unit is provided for locking the door in its closed position during movements of the shoe carrier elements along the track.
  • the control unit is also used to have the conveyor halt a respective one of the shoe carrier elements in front of the inlet and/or outlet opening during a stop, wherein the control unit is designed to only allow the door to be unlocked during such a stop.
  • the control unit is connected to a user interface for controlling a moving/stopping of the conveyor and locking/unlocking of the door in dependence of a user specific code, such that the user specific code corresponds to or gets to correspond to a specific one of the shoe carrier elements getting halted by the conveyor in front of the inlet and/or outlet opening.
  • the invention thus makes it possible for users to themselves directly place shoes into the system after he or she has worn them, and users themselves can directly take shoes out of the system again after a washing cycle has been performed when he or she needs a clean pair again.
  • the shoe handling and washing system thus can easily be placed at or near a work floor itself where the shoes are actually used and put on and off by users. It is even possible to keep the shoes stored inside the system according to the invention after they have been washed. Thus it is possible to get the shoes cleaned without having to transport them towards and back from an external or internal laundry or the like.
  • the system for the first time makes it possible to truly integrate a handling and washing of shoes right there where a starting and finishing of a work process takes place.
  • the handling and washing system forms a logistic system that regulates and controls individual pairs of shoes during loading, washing, and unloading.
  • the housing helps to prevent all the different and unexperienced individual users from getting injured during operation of the system, also helps to keep the shoes that are stored therein clean after a washing cycle has been performed thereto, and helps to prevent unauthorized use or theft of the shoes.
  • the shoe handling and washing system for example can get to learn which pair of shoe carrier elements gets to correspond to a certain user specific code, such that during unloading after a washing cycle has been performed, the same user can automatically be given access to his or her own pair of shoes by having that pair of shoe carrier elements getting halted in front of the door when that user specific code is held in front of or entered into the user interface.
  • the shoe handling and washing system in addition or in the alternative can also get to learn which pair of shoe carrier elements gets to correspond to a certain size and/or type of shoes, such that during unloading after a washing cycle has been performed, users can automatically be given access to a size and/or type of shoes that corresponds to their own size and/or type by having a pair of shoe carrier elements getting halted in front of the door that corresponds thereto when a user specific code is held in front of or entered into the user interface.
  • the inlet and/or outlet opening can be given all kinds of shapes and dimensions, but preferably is dimensioned such that each time the conveyor is halted only one pair of shoe carrier elements at a time gets accessible for the user to be loaded and/or unloaded via the inlet and/or outlet opening after the door is unlocked and opened.
  • the invention makes it possible to build the system compact and economic. It even makes it possible for the shoes to get moved through the bowl with cleaning liquid multiple times during a washing cycle over and over again without having to be unloaded and loaded again.
  • the shoes when arriving at the lower bend section, get moved into the cleaning liquid with which the bowl is filled, then get forcedly moved along the bend section through this cleaning liquid, and then get moved upwards out of the cleaning liquid again.
  • the shoes then get moved upwards along one of the leg sections, along the upper bend section and downwards along the other leg section. During this movement all the cleaning liquid that then drips of the shoes advantageously falls downwards back into the bowl.
  • Left and right ones of each pair of shoes can be equipped with electronically or optically recognizable identifiers, like for example RFID-chips. Those identifiers then can include a unique code for that shoe, but for example also information about the shoe being a left or right one, the type and age of the shoe, and/or the size of the shoes. Readers for electronically or optically reading/scanning those identifiers, like for example RFID-readers, can be provided on the system, for example located at or near the inlet and/or outlet opening, such that the identifiers can automatically be read when a pair of shoes is loaded onto a specific pair of shoe carrier elements and/or when a pair of shoes is unloaded from that specific pair of shoe carrier elements.
  • Those readers can be connected to and controlled by the control unit.
  • writers for electronically or optically writing/rewriting those identifiers like for example RFID-writers, can also be provided on the system, for example located at or near the inlet and/or outlet opening, such that the identifiers can automatically be (re)written when a pair of shoes is loaded onto a specific pair of shoe carrier elements and/or when a pair of shoes is unloaded from that specific pair of shoe carrier elements.
  • Those writers can be connected to and controlled by the control unit.
  • a user then may announce himself at the user interface and indicate that he wants to take out a pair of shoes of a certain size and/or type.
  • the control unit's software then may steer the user to the outlet opening and have the conveyor halt a specific pair of shoe carrier elements with shoes of the aimed size and/or type behind that outlet opening. Subsequently the control unit may allow the door to automatically or manually be unlocked and opened during such a stop.
  • each individual user can simply go towards the handling and washing system where the user may find an already opened inlet opening or where the user may request the control unit, via the interface, to open the inlet opening such that the user can place the pair of shoes on the specific pair of shoe carrier elements that is waiting behind the inlet opening.
  • the shoes then automatically may have their identifiers read and the control unit may link them to that specific pair of shoe carrier elements they are placed upon.
  • the control unit then may allow the door to automatically or manually be closed and locked again and have the conveyor halt another specific empty pair of shoe carrier elements behind the inlet opening. This procedure can be repeated for other users. As soon as all or a sufficient number of the shoe carrier elements thus has been filled with used shoes, or when a timer gives a signal, the control unit can all by itself start a washing cycle.
  • control unit can also be used to monitor aging and history of the shoes and/or user behaviour information like frequency and time span of being taken out by a specific user. Data coming out of this monitoring then for example can be used for having the interface indicate that a certain pair of shoes needs to be thrown away, inspected, have maintenance performed thereto, etc.
  • the washing unit comprises a fluid inlet for filling the bowl with a cleaning liquid like a washing, disinfection or rinsing liquid, and a fluid outlet for draining the bowl therefrom.
  • the inlet for example can be connected via a controllable valve and/or pumping unit to one or more reservoirs that are filled with specific cleaning liquids or cleaning liquid concentrates.
  • the inlet can also be connected via a controllable valve and/or pumping unit to a water supply system.
  • the concentrate can be mixed inside the bowl with the cleaning liquid concentrate.
  • the outlet for example can be connected via a controllable valve or pumping unit to a drain or sewer.
  • a heating element can be provided for heating up the cleaning liquid filled therein. This may help to improve the washing result.
  • the bowl can be filled with cleaning liquid.
  • the washing cycle can be performed during which the conveyor moves the shoes at for example a constant speed along the track during a predetermined time period or for a predetermined number of full turns along the track.
  • the bowl can be successively filled and emptied with for example a washing liquid, a disinfection liquid and/or a rinsing liquid.
  • the conveyor can be temporarily stopped if desired.
  • the bowl is drained empty via the outlet.
  • the shoes can be given time to dry. If desired (hot) drying air can be fed into the system for this via suitable nozzles. During this drying the conveyor may or may not continue to move the shoe carrier elements along the track. After the shoes have sufficiently dried, the shoes can be unloaded from the shoe carrier elements.
  • the shoe carrier elements preferably are movable along the track such that when moved downwards along one of the leg sections, shoes that are loaded onto them are held with their soles down, in particular with their noses pointing slanting downwards, and such that when moved upwards along the other one of the leg sections, the shoes are held with their soles up, in particular with their noses pointing slanting upwards.
  • This positioning helps in a thorough cleaning of the shoes.
  • the shoes are automatically turned upside down. This helps the cleaning liquid to easily flow out of the insides of the shoes when coming out of the bowl.
  • the control unit can also be designed to, for example if it detects that a certain percentage of shoe carrier elements has gotten loaded with shoes, automatically start a washing cycle. During this washing cycle, the control unit can first have the door locked, then have the bowl filled with cleaning liquid, and then have the conveyor move the loaded shoes at a constant speed along the track including through the cleaning liquid in the bowl. After the washing cycle has ended the control unit can then have the bowl emptied and after the shoes have been given enough time to dry, have the door freed for unlocking.
  • Each shoe carrier element may comprise a releasable shoe clamp for fixating a shoe loaded onto it.
  • each shoe carrier element may comprise a nose supporting portion over which a nose of a shoe is positionable.
  • the conveyor may comprise a drivable flexible pulling organ, in particular a chain, to which the shoe carrier elements are connected one behind the other at fixed intervals.
  • the pulling organ can be run over guiding wheels, in particular toothed wheels, that are provided at the bend sections.
  • a controllable drive unit can be provided for driving the pulling organ.
  • Each shoe carrier element can be fixedly connected to this pulling organ.
  • each shoe carrier element gets hingedly connected to the pulling organ whereas a supporting arm that is also hingedly connected to the pulling organ is hingedly connected to each shoe carrier element.
  • a triangular support connection is provided that is well able to deal with all the forces during movement along the track while at the same time offering sufficient flexibility for the shoe carrier elements to be moved along the bend sections.
  • the invention also relates to a use of the shoe handling and washing system according to claim as well as to a method for operating the shoe handling and washing system according to claims 14-15.
  • the shoe handling and storage system has been indicated with the reference numeral 1.
  • the system 1 comprises an upright positioned housing 2 with a front wall 3.
  • An inlet/outlet opening 4 is provided in the front wall 3.
  • An operable door 6 is provided which can be moved between a closed position ( fig. 1 ) and an open position ( fig. 6 ).
  • the door 6 here is formed by a flexible plate that is connected to a piston-cylinder organ 7 that is controllable by a control unit C (not shown) for having the door 6 moved along guides 8 between its closed position ( fig. 8a ) and its open position ( fig. 8b ).
  • the housing 1 encloses a space inside which two endless chain conveyors 10 are provided next to each other which each run over an upper toothed wheel 11 and a lower toothed wheel 12.
  • the wheels are rotatable in bearings 11', 12' that are connected to side walls 13 of the housing 1.
  • the upper wheels 11 together are drivable in rotation by means of a drive unit D (only shown in fig. 9 ), for example an electromotor, that is controllable by the control unit C.
  • the chain conveyors 10 run along their wheels 11, 12 while following an endless loop-shaped track.
  • This track defines a front vertical leg section 14 and a back vertical leg section 15 that are connected to each other by an upper bend section 16 and a lower bend section 17.
  • Linear guides 18 are provided along the vertical leg sections 14, 15 which delimit the chain conveyors 10 sideways. See fig. 5 .
  • the upper and lower bend sections 16, 17 are defined by outer circumferences of the toothed wheels 11, 12.
  • Shoe carrier elements 20, here twenty-five in total, are connected one behind the other at fixed intervals to distinctive links of each of the chain conveyors 10 such that they are equally divided along the chain conveyor 10 and each project (radially) outwardly therefrom.
  • Each shoe carrier element 20 comprises a nose supporting portion 21 over which a nose of a shoe 22 can be placed. See also fig. 5 and 7 .
  • Each shoe carrier element 20 further comprises a releasable shoe clamp 23 that is designed to automatically grip behind a heel portion of a shoe 22 as soon as that shoe 22 is slid far enough over the nose supporting portion 21.
  • the nose supporting portion 21 is hingedly connected to the chain conveyor 10.
  • the clamp 23 is hingedly connected to the nose supporting portion 21.
  • a supporting arm 25 is provided that with one end is hingedly connected to the chain conveyor 10 and with another end to the nose supporting portion 21.
  • a spacing of a few links of the chain conveyor 10 is left free between the hinge connections of the nose supporting portion 21 and the supporting arm 25 to the chain conveyor 10.
  • the adjacent pairs of shoe carrier elements 20 have the pairs of shoes 22 move along with the chain conveyors 10 along the track such that when moved downwards along the back vertical leg section 15, the pairs of shoes 22 are held with their soles up while their noses point slanting downwards, and such that when moved upwards along the front vertical leg section 14, the pairs of shoes 22 are held with their soles down while their noses point slanting upwards.
  • the chain conveyors 10 When driven by the drive unit D, the chain conveyors 10 take along the plurality of shoe carrier elements 20 to move along the loop-shaped track. With this the pairs of shoe carrier elements 20 during their upwards travel along the front vertical leg section 14 also get moved along the inlet/outlet opening 4.
  • the chain conveyor 10 can each time be halted with a particular empty pair of the shoe carrier elements 20 in line with the inlet/outlet opening 4, by means of having the control unit C stop the drive unit D as soon as this aligned position is achieved. In the open position of the door 6, an operator or user then can manually place a pair of shoes 22 onto that particular pair of shoe carrier elements 20.
