Definitions

  • the invention relates to a method for loading and / or unloading laundry machines, in particular washing machines, dryers or the like, according to the preamble of claim 1. Furthermore, the invention relates to a device for loading and / or unloading laundry machines, in particular washing machines, dryers or the like, according to the preamble of claim 8.
  • Laundry machines such as washing machines and dryers in particular, are loaded and / or unloaded with laundry in batches or batches. Each batch of laundry contains a large number of items of laundry that can be treated in the same way.
  • a laundry sack contains an amount of laundry that forms a batch or batch of laundry.
  • the laundry bags are suspended from rails and transported along a conveyor line formed by the rails to the laundry machine to be loaded.
  • the conveyor section can be designed in sections as a downhill conveyor section.
  • the sequence of treatment of the laundry is predetermined by the sequence of the laundry bags containing the laundry along the conveyor line.
  • a selective treatment of the laundry in the laundry bags for example the successive treatment of the same or similar laundry in laundry bags at different points on the conveyor line, is not possible.
  • the further transport of the laundry bags along the rails of the conveying path in particular in areas of non-powered gravity conveying, is subject to interference.
  • the unloading and / or removal of the washed and preferably dried laundry are similarly disadvantageous. So far, this has been done with laundry transport containers or belt conveyors.
  • the invention is based on the object of creating a method and a device for batch-wise loading of laundry machines with laundry and / or for the batch-wise or batch-wise transporting away of the treated laundry, which provides a reliable, in particular failure-prone, and largely arbitrary loading of laundry machines with laundry of different types to be treated and / or allow the treated laundry to be transported away reliably and easily.
  • a method for solving this problem has the measures of claim 1.
  • the laundry is transported to at least one storage device which enables the laundry to be temporarily stored. It is also provided to transport the laundry to be washed specifically from the store to the laundry machine and thereby load it with the desired laundry and / or to transport the laundry unloaded from the laundry machine used for washing or a subsequent laundry machine to another store.
  • the laundry machine can be specifically loaded with laundry from the store arranged in front of it.
  • the at least one storage facility shortens the conveyor routes and is therefore less susceptible to malfunctions.
  • a loading receptacle which transports the laundry to laundry machines.
  • the holding capacity of the loading receptacle or the unloading receptacle is preferably selected such that it can hold such an amount of laundry that corresponds to a batch of laundry or a batch of laundry and is thereby adapted to the loading capacity of the laundry machine. It is also conceivable, however, to form a batch of laundry or a batch of laundry from the laundry of several loading receptacles and to gradually load the laundry machine with several parts of the batch of laundry. If necessary, the unloading receptacle can also have a lower receiving capacity than the loading receptacle.
  • the amount of laundry in the receptacle can differ from the amount of laundry in the loading receptacle.
  • the amount of laundry in the receptacle can be less than the amount of laundry required to form a laundry batch or a laundry batch.
  • the reverse procedure is followed when the treated, preferably washed and dried, laundry is unloaded. During unloading, this laundry is transferred in batches or partially in batches to the unloading receptacle, which reloads the treated laundry into the store for temporary storage.
  • the treated laundry is then deliberately transferred from the store, namely in accordance with the requirements, in batches or batches to a receptacle, which then feeds the laundry for further use.
  • An advantageous embodiment of the method provides for the receptacle loaded with laundry to be transported from a discontinuous conveyor to the store and the laundry to be transported from the store from the loading receptacle with a preferably different discontinuous conveyor to the laundry machine to be loaded.
  • the treated laundry is unloaded from the same laundry machine or another subsequent laundry treatment machine, the treated laundry is loaded in batches into the unloading receptacle, which is transported by another, first discontinuous conveyor to another store.
  • a desired batch of laundry is created from this memory loaded into a receptacle assigned to it, which is transported away by another second discontinuous conveyor.
  • the loading and unloading of the store can take place independently of one another.
  • the order in which the store is loaded with laundry can differ from the order in which the laundry is unloaded from the store. This enables laundry, in particular laundry of a certain type, to be removed from the store in a targeted manner. This results in flexible unloading of the respective laundry machine.
  • the method can be developed in such a way that laundry from the receiving and / or unloading receptacle can be delivered to any of a plurality of storage locations for laundry in the respective store. It is thereby possible to store laundry from the intake or unload intake in any free memory location of the respective memory.
  • the storage locations of the storage tanks can be filled with laundry as required. However, it is also conceivable that such a storage space or storage spaces in which there is not yet a sufficient amount of laundry for a complete batch of laundry can be reloaded, as it were, by transferring laundry of the same type from another receptacle or unloading receptacle to the already partially filled laundry same storage space is dumped.
  • the method can be designed in such a way that electronic navigation devices are assigned to the conveyors, in particular discontinuous conveyors, due to the arbitrary filling of the memory locations without an order system, which preferably deliver the data, in particular position data, each time a respective memory location is filled and / or emptied.
  • This data is stored electronically so that a second conveyor can access this data, preferably position data.
  • a controller can, for example, control the second conveyor, in particular the discontinuous conveyor, for the targeted removal of laundry from a specific storage location. In particular, it is thus possible to remove laundry of the same type from different storage locations one after the other.
  • a weighing device assigns a weighing device to at least one receptacle, the loading receptacle and / or the unloading receptacle.
  • the laundry weight can thus be determined in at least one receptacle, unloading receptacle and / or the loading receptacle.
  • the weight of the laundry delivered to a specific storage location can also be stored, preferably in addition to the data, in particular Coordinates, via the position of the respective memory location. This means that the loading status of each storage location in the respective storage facility is known. It is preferably also known which laundry, preferably type of laundry, is in which storage space and which storage space is empty. It is also possible in this way to refill a storage space that is not yet sufficiently filled for a batch of laundry.
  • a device for solving the aforementioned object has the features of claim 8.
  • this device In front of the laundry machine to be loaded and / or behind the same laundry machine or another laundry machine, this device has one or one memory each with a plurality of memory locations.
  • the receptacle or discharge receptacle containing the laundry can be moved by a conveyor to the store.
  • Another conveyor with a receptacle or with a loading receptacle for laundry from the respective store is provided in order to move the laundry in the loading receptacle to the laundry machine and / or to transport it away from the store in a receptacle.
  • the at least one store with several storage spaces replaces a long conveyor line and leads to a compact, space-saving device.
  • the loading and unloading of the store can take place independently of one another.
  • the device according to the invention thereby creates independent, flexible loading of laundry machines that is not susceptible to failure.
  • the at least one memory has a plurality of identical and / or contiguous memory locations.
  • the storage facility or each storage facility can hold a sufficient amount of laundry to be treated.
  • the same and / or contiguous storage spaces make the device very compact, so that it requires less space than the conventional rail-bound conveyor systems with long conveyor routes.
  • the memory locations are arranged in a grid-like manner, in particular in rows and rows next to one another and / or one behind the other. This leads to the fact that the walls of adjacent storage units are in direct contact with one another and common walls can be present between adjacent storage locations. This results in a connection between the storage locations at the same time.
  • Storage spaces with a square or hexagonal cross-section are particularly advantageous because there are no gaps or free spaces between all adjacent storage spaces. As a result, the entire floor area of the respective storage unit is available for the storage spaces.
  • the cross-sections or base areas of the at least one receptacle of the loading receptacle and / or the unloading receptacle preferably correspond to the base area or the cross-section of each of the identically designed storage locations.
  • the laundry can be reliably and completely loaded into the respective storage location and, conversely, the laundry located there can be completely loaded from the respective storage location into another receptacle or loading receptacle. This means that malfunctions and incorrect loading are ruled out.
  • each of the storage spaces of the at least one storage unit which are designed in the same way, is provided with a base which can be opened to unload the respective storage space.
  • the soil does not necessarily have to be part of the storage tank.
  • the opening process of the bottom can preferably only be released after the receiving and / or loading receptacle for the laundry has moved out of this storage space exactly below the relevant storage space.
  • the bottom remains open only for the duration of the takeover of the laundry items from the storage space. After the laundry has been taken over, it is closed again.
  • the conveyors are provided with controls and data memories according to a particularly advantageous embodiment of the device.
  • the controls have means for determining the position of the storage location at which the respective receptacle and / or unload receptacle has been emptied.
  • the position data can be stored in the data memory and can at least be used by the conveyor, in particular the discontinuous conveyor, with the receptacle or loading receptacle, in order to drive it specifically to such a storage location from which the receptacle or loading receptacle is to be filled with laundry.
  • the storage of the position data in particular also data on the type of laundry, and a corresponding control, preferably of both conveyors, it is known from the respective control which storage space is occupied and which laundry is in the respective occupied storage space.
  • the second conveyor which has the loading receptacle or another receptacle, can then move to a storage location containing such laundry for the targeted picking up of certain laundry and transport the laundry transferred from the storage location to a corresponding loading position on the laundry machine for loading the laundry machine or the treated laundry from its storage location Pick up and transport away the storage for treated laundry in a targeted manner.
  • At least some, preferably all, conveyors of the device are preferably designed as discontinuous conveyors.
  • the conveyors can be discontinuous conveyors of the same principle and / or of the same type. Provision is also preferably made for the discontinuous conveyors to be designed in the manner of a crane, robot or gripper.
  • the discontinuous conveyors especially crane-like discontinuous conveyors, portal cranes, storage cranes, charging cranes or the like can be.
  • Such discontinuous conveyors which are also referred to in technical jargon as "process cranes”, can be programmed with regard to their movement sequences and enable a certain position to be approached exactly. That is why they allow high transport speeds that are greater than with known bag conveyor systems. Above all, the transport routes of the discontinuous conveyor can be shorter than with known bag conveyor systems.
  • the at least one receptacle or the loading receptacle and / or entrant receptacle each represent the load-handling device for the laundry.
  • programmable robots can also be used as discontinuous conveyors. These can be simple robots because the conveyors, in particular continuous conveyors, for the implementation of the invention only have one load-bearing means that can be moved in one plane, preferably a horizontal plane, in two dimensions or in two axes, namely the at least one receptacle, the loading receptacle and / or the unloading receptacle, must have.

  • the load-handling device of the first discontinuous conveyor 32 is designed as an unloading receptacle 41 for the washed and dried laundry from the dryer 25.
  • the load handling device of the second discontinuous conveyor 33 is formed by a receptacle 42.
  • the discharge receptacle 41 and the receptacle 42 are preferably designed as a container. In particular, these are rigid containers.
  • At least the unloading receptacle 41 has a capacity that of the laundry load corresponds to each of which can be dried in a dryer 25.
  • the receptacle 42 preferably has the same capacity. It is conceivable that the unloading receptacle 41 and the receptacle 42 have different capacities, whereby the capacity of the receptacle 42 should expediently correspond to at least the capacity of the respective storage space 31.
  • the discharge receptacle 41 and the receptacle 42 are preferably designed in the same way, in particular have the same cross section. Otherwise, the unloading receptacle 41 and the receptacle 42 correspond to the receptacle 23 and the loading receptacle 24 of the discontinuous conveyors 15 and 16, especially with regard to their shape and possibly also the size Fig. 1 . Reference is made to this.
  • the unloading receptacle 41 and the receptacle 42 are completely open on their upper sides, the discontinuous conveyors 32, 33, in particular their bridges 37 and 38, being designed such that they completely leave the open upper sides of the unloading receptacle 41 and the receptacle 42 free.
  • the undersides of the unloading receptacle 41 and the receptacle 42 are provided with a bottom.
  • the base is designed in such a way that it can be opened for unloading the unloading receptacle 41 and the receptacle 42. This can be done in exactly the same way as above in connection with the receptacle 23 and the loading receptacle 24 in FIG Fig. 1 device shown.
  • the device of the Fig. 2 can also be used for laundry that is not dried in dryers 25. Then the washed laundry coming from the drainage device is first loosened up by a shaker. In particular, laundry cakes coming from a dewatering press are broken up and / or loosened. The unloading receptacle 41 is then charged with the loosened laundry. This can be done directly via the discharge end of the shaker, but also via a conveyor downstream of the shaker.
  • the laundry washed in a respective tunnel washing machine 10, dehydrated and dried in a dryer 25 is unloaded from the respective dryer 25 in batches or batches.
  • the entire laundry load of a respective dryer 25 preferably arrives at the discharge conveyor 28.
  • the laundry load is then preferably completely into the unloading receptacle 41 via the discharge end 30 of the discharge conveyor 28 transferred so that the unloading receptacle 41 is loaded with the laundry load.
  • the unloading receptacle 41 is then moved by the first discontinuous conveyor 32 over any or selected empty storage space 31 of the store 29.
  • the unloading receptacle 41 is preferably moved over such an empty storage space 31 which can be approached in the shortest possible way.
  • the laundry from the unloading receptacle 41 reaches the respective storage space 31 of the store 29 due to gravity, in that the bottom of the unloading receptacle 41 is automatically, in particular mechanically, opened to transfer the laundry from the unloading receptacle 41 into the relevant storage space 31 and again after the unloading receptacle 41 has been emptied is closed.
  • the receptacle 42 is moved by the second discontinuous conveyor 33 for loading the same between the store 29 and the subsequent discharge conveyor 34.
  • the receptacle 42 is first driven in a targeted manner by the second discontinuous conveyor 33 under the desired storage space 31 of the store 29 to be emptied, with the bottom of the receptacle 42 closed.
  • the bottom of the relevant storage space 31 is then opened so that the laundry is removed by gravity the storage space 31 enters the receptacle 42.
  • the laundry is thereby reloaded from the storage space 31 into the receptacle 42.
  • the second discontinuous conveyor 33 moves the receptacle 42 with the laundry located therein, in particular a washed and dried batch of laundry, over the discharge conveyor 34 and the receptacle 42 is emptied above the discharge conveyor 34.
  • the bottom of the receptacle 42 is opened automatically, so that the laundry falls from the receptacle 42 into or onto the discharge conveyor 34 again as a result of gravity. The unloading process of the dryer 25 is thus completed.
  • the storage spaces 31 of the memory 29 can be loaded with washed and dried laundry in a random manner. Then, preferably with a position determining device of the first discontinuous conveyor 32, it is determined via which storage space 31 the unloading receptacle 41 has emptied the laundry. This position is stored in a data memory. The stored position data or, alternatively, a previously defined stored number of the unloading receptacle 41 are made available to the control of the discontinuous conveyors 32 and / or 33 so that they can access them. It is also conceivable that, when the laundry is unloaded into a preferably arbitrary storage space 31, information on the laundry that has been delivered by the unloading receptacle 41 in the relevant storage space 31 is also determined and stored.
  • a common control for both discontinuous conveyors 32 and 33 or, alternatively, separate controls for each discontinuous conveyor 32 and 33, both of which can access the stored data, namely position data and / or the number of the relevant memory location 31, are used to target the receptacle 42 to proceed under that storage space 31 whose laundry, in particular laundry batch, is to be removed from the storage space 31 next and delivered to the delivery conveyor 34.
  • the receptacle 42 which is also provided with a position determination device, moves to that stored position which corresponds to the desired and / or selected memory location 31.
  • the second discontinuous conveyor 33 moves the receptacle 42 over the discharge conveyor 34.
  • the receptacle 42 is then opened, whereby the laundry of the laundry load in the receptacle 42 automatically and completely out of the receptacle 42 reaches the discharge conveyor 34.
  • the Fig. 3 shows a device according to a third embodiment of the invention. This device represents a combination of the devices described above Fig. 1 and 2 represent.
  • a store 13 and two discontinuous conveyors 15 and 16 associated therewith are arranged in front of the conveyor washing machines 10. Behind the conveyor washing machines 10, namely behind the dryers 25 following the conveyor washing machines 10 with the discharge conveyor 28 assigned to them, a further memory 29 is provided, to which two discontinuous conveyors 32 and 33 are also assigned.
  • Untreated laundry in particular dirty laundry, can be temporarily stored in the memory 13 in front of the conveyor-type washing machines 10.
  • treated laundry in the embodiment shown washed, drained and dried laundry, can be temporarily stored behind the dryer 25 in the second memory 29.
  • each store 13 and 29 has two discontinuous conveyors 15 and 16 on the one hand and two discontinuous conveyors 32 and 33 on the other hand are assigned, each memory 13 and 29 can be operated by the discontinuous conveyors 15, 16 or 32, 33 space-saving and individually.
  • the memory 13 is loaded by the respective receptacle 23 of the discontinuous conveyor 15.
  • the store 13, namely its respective storage space 14, is unloaded from the loading receptacle 24 of the discontinuous conveyor 16 and the desired conveyor-type washing machine 10 is loaded with the laundry in the loading receptacle 24.
  • the dried laundry is taken from the respective dryer 25 by an unloading receptacle 41 and reloaded into the desired storage space 31 of the memory 29.
  • a batch of treated laundry can be taken from the receptacle 42 from the storage unit 29, namely from the respective desired storage location 31 thereof.
