Definitions

  • the present invention relates to an assembly for washing, drying and polishing cutlery, comprising:
  • Such an assembly is known to the extent that the modules of which it is composed, namely the washing device and the polishing device, are both known modules that are to be found in combination in kitchens, in particular catering kitchens of restaurants, hotels etc. However, in those places they are in every case modules working completely separately from each other. An operative in each case takes cutlery washed with the washing device by hand over to the polishing device for polishing of the cutlery there, so that the cutlery in the end looks sparkling again, and tarnish stains as a result of water that has dried on it are avoided.
  • Such washing devices and polishing devices for treating cutlery in the catering trade have already been known for decades.
  • the object of the present invention is to provide an assembly of the type mentioned at the beginning, in the case of which assembly the cutlery is washed, dried and polished with a minimum of human effort.
  • the abovementioned object is achieved according to the invention by providing an assembly of the type mentioned at the beginning, which according to the invention is characterized in that the washing outlet and polishing inlet can be connected to each other.
  • the washing device and the polishing device in this case remain two separate modules, which is very practical not only for maintenance and repairs, but also for replacement.
  • the outlet of the washing device called the washing outlet
  • the inlet of the polishing device called the polishing inlet
  • the washing outlet has a washing outlet aperture and the polishing inlet has a polishing inlet aperture, and if the washing outlet aperture is provided above the polishing inlet aperture in such a way that the cutlery is conveyed from the washing outlet aperture into the polishing inlet aperture under the influence of gravity.
  • the washing outlet aperture will be situated vertically above the polishing inlet aperture. In this way the cutlery washed and discharged by the washing device can fall directly out of the washing device into the polishing device.
  • a conveyor belt extends between the washing inlet and the washing outlet, in order to convey the cutlery through the washing device, and if washing jets are provided along said conveyor belt for the purpose of washing cutlery passing along the conveyor belt with a jet of washing liquid.
  • washing jets are provided along said conveyor belt for the purpose of washing cutlery passing along the conveyor belt with a jet of washing liquid.
  • the washing inlet opens out above the upstream end of the conveyor belt - at any rate assuming that the conveyor belt is not made unnecessarily long - and if the washing outlet, or at any rate the washing outlet aperture, lies below the downstream end of the conveyor belt. It then becomes possible to place the cutlery on the conveyor belt from the top, or simply to let it fall onto the conveyor belt, and to discharge the cutlery directly at the end of the conveyor belt by way of the washing outlet aperture. Having the washing inlet open out above the conveyor belt also means that the risk of water coming out of the washing device is reduced. This makes it possible to have the washing device operating continuously, or at any rate operating while cutlery to be washed is being fed to the washing device.
  • the conveyor belt comprises a conveyance surface provided with apertures, in particular a perforated conveyance surface.
  • Fixed walls may be provided along the conveyance surface if desired, in order to prevent the cutlery from falling off the conveyor belt, or at any rate off the conveyance surface. These walls can be solid or possibly fully or partially provided with apertures.
  • washing jets and/or rinsing jets are provided above and below the conveyance surface, in order to permit spraying of cutlery lying on the conveyance surface from the top and from the bottom.
  • the conveyor belt can be, for example, a roller conveyor, driven or otherwise.
  • the conveyor belt is, however, of the so-called endless type.
  • the conveyor belt is composed of an endless chain of U-shaped elements.
  • the side legs of the U-shaped elements then form, as it were, the side walls of the conveyor belt that prevent the cutlery from falling off the conveyor belt, and the web of the U-shaped elements that connects said legs to each other then forms the conveyance surface of the conveyor belt.
  • the side walls of the conveyor belt also move along with the cutlery, which reduces the risk of blockages occurring on the conveyor belt because of cutlery becoming jammed between the opposite walls. This is because the walls move along with the conveyor belt, so should cutlery become jammed the jammed piece or pieces of cutlery will simply be conveyed further and will not obstruct other cutlery.
  • the washing device comprises sensors for detecting cutlery, which sensors are connected to switching means that are designed to switch off the washing device, or at any rate to place it in a standby mode if no cutlery has been detected for a predetermined period of time.
  • This predetermined period of time can be, for example, 10 seconds, 30 seconds, 1 minute or more.
  • These switching means will then switch off the conveyor belt and/or the washing jets and/or rinsing jets.
  • the washing liquid and the rinsing liquid will still be kept at temperature, at any rate in the standby mode. It is possible to save energy in this way, and the noise produced by the assembly is also minimized, namely occurs only in those periods when the assembly is actually in use.
  • washing cycle time of the washing device is less than or equal to the polishing cycle time of the polishing device.
  • Washing cycle time in this context is meant in particular to convey the quantity of cutlery that can be processed by the washing device per unit time.
  • Polishing cycle time in this context is meant in particular to convey the quantity of cutlery that can be processed by the polishing device per unit time.
  • the washing device comprises switching means - which, as will be clear, can be controlled by the abovementioned sensors or also otherwise - for switching the washing device on and off, or at any rate for placing the washing device in or taking it out of a standby mode, and if these switching means are further connected to the polishing device in order to switch the latter simultaneously on or off, or to or from the standby mode, possibly with a predetermined delay. In this way it can be ensured that when the washing device is switched on or off the polishing device is also switched on or off respectively. It is then unnecessary to perform two manual switching operations.
  • the present invention can in principle be embodied with various types of washing device, so not just the type that is specifically described above.
  • the type of washing device described above is, however, the preferred embodiment.
  • the same also applies to the type of polishing device.
  • Many polishing devices known from the prior art can be used for the type of polishing device. It is, however, preferable according to the invention to use a specific type of polishing device, as is known, for example, under the brand name Rösler, model CD 8000L.
  • Such a type of polishing device comprises:
  • Such a polishing device is also known from EP 0,882,424. With a suitable choice of the granular material the polishing device can also dry the cutlery. In that case it is possible for the cutlery to be conveyed without any drying at all from the washing device to the polishing device.
  • the invention relates to a washing device intended for an assembly according to the invention.
  • Fig. 1 shows an assembly according to the invention comprising a washing device 1 and a polishing device 2.
  • the washing device 1 is shown with the cover 3 removed.
  • the washing device 1 comprises a superstructure 4 and a substructure 5.
  • the substructure 5 contains systems (not shown) for feeding in washing liquid and spraying liquid, and for storage of such liquids, in addition to other not so special parts for the functioning of such a device.
  • An endless conveyor 5 is accommodated in the superstructure.
  • Said endless conveyor is composed of U-shaped segments, which are connected together to form a chain.
  • One segment is indicated by 6.
  • Each segment consists of two vertical side walls 7 and a bottom 8.
  • the bottom parts 8 are provided with apertures, or if you like perforations.
  • the side walls 7 can, if desired, also be provided with such apertures or perforations, but in this case the side walls 7 are solid in each case.
  • the direction of conveyance of the top part of the endless conveyor 9 is shown by arrow 10.
  • a washing inlet aperture 11 is provided in the cover 3 above the upstream part of the conveyor 5. Dirty cutlery can be placed on the conveyor 5 by way of the washing inlet aperture 11. The conveyor 5 will then convey this cutlery in the direction of arrow 10 past jet means 12 for washing liquid.
  • Said jet means 12 comprise jet pipes provided transversely along the top of the upper part of the conveyor 5 and also transversely along the bottom of the upper part of the conveyor. The top jet pipes 13 are positioned with the jet nozzles directed downwards, and the bottom jet pipes 14 are positioned with the jet nozzles directed upwards.
  • a rinsing assembly 15 with a top jet pipe and a bottom jet pipe is shown downstream of the washing liquid jets 12.
  • the top jet pipe and also the bottom jet pipe of this rinsing assembly have the jet nozzles directed towards the conveyor 5.
  • Downstream of the rinsing means 15 the conveyor 5 is guided over a turning point 16.
  • the washing outlet 17 is provided after the turning point 16.
  • Said washing outlet 17 comprises a guide and has a washing outlet aperture (not shown) on the underside.
  • the washing outlet aperture is situated directly above the polishing inlet aperture of the polishing device 2.
  • Said polishing inlet aperture is provided in the cover 18 of the polishing device 2 and is situated directly above the central pipe part 19 of the vibrating tank 20 provided in the top part of the polishing device 2.
  • the polishing device 2 is of the type with a vibrating tank 20 filled with maize granules 21.
  • a perforated plate 22 is provided, extending helically, in this vibrating tank, which perforated plate in particular makes slightly more than one revolution.
  • the perforations in the helical plate 22 have a diameter that is greater than that of the granular material with which the tank 20 is filled.
  • This granular material in this example consists of maize granules, but it can also be another granular material.
  • Cutlery emptied into the vibrating tank 20 by way of the pipe part 19 will be polished and preferably also dried under the action of the granules 21. If desired, it is possible to dispense with drying means in the washing device. Under the influence of the vibrating action to which the vibrating tank 20 is subjected by vibrating means (not shown) that are known per se, the cutlery moves by itself up along the helical plate 22 towards the polishing outlet 23.
  • a sensor 24 can be provided in the washing device 1, for example at the discharge end of the conveyor 5. It can be seen with this sensor 24 whether cutlery is present on the conveyor 5.
  • This sensor 24 can be connected to switching means, which are designed in such a way that if the sensor 24 has not detected any further cutlery for a period of, for example, 30 seconds, the switching means switch the washing device 1 to a standby mode. In standby mode the washing liquid jets and the rinsing jets will not be operational and the conveyor 5 will also be at a standstill. The systems for maintaining the washing liquid at temperature and otherwise for keeping the washing liquid ready in operational mode will continue to work in the standby mode.
  • This sensor 25 is also connected to switching means for switching the washing device 1 on and off.
  • washing device 1 When the washing device 1 is in the switched-off or standby mode, as soon as this sensor detects that cutlery is passing through washing inlet aperture 11 the washing device will be put into full operation.
  • the polishing device 2 will also be put into operation, possibly with a delay.
  • sensor 25 By connecting sensor 25 to a time counter, said sensor can also be used for switching off the washing device.
  • the washing device will then be switched off as soon as a period of time that is equal to or greater than the preceding cycle time of the washing device has elapsed. In that case it is possible, if desired to dispense with sensor 24.
  • the switching system for placing the washing device 1 in standby mode in the case of the type of polishing device described with reference to the figures will not be connected to the polishing device for placing that polishing device on standby. This is because said polishing device cannot be kept at temperature when in standby mode.
  • a sensor 25 can be provided in a corresponding manner at the washing inlet aperture 11.
