Definitions

  • This invention relates generally to the refurbishment of pile carpet, especially carpet tiles, to provide extended wear life without a detrimental affect on the surrounding due to a reduced aesthetic effect by the existing pile carpet due to dirt and/or matting of the pile on the face of the tile.
  • US-A-4926520 discloses a method to refurbish pile carpet products such as a carpet tile by a scrubbing action caused by a scrubbing device as well as by projecting a stream of cleaning and rinsing fluid against the pile product to clean the dirt from the product and allowing the product to dry after the cleaning thereof.
  • FR-A-2 583 075 discloses a process for painting a pile carpet which can be preceded by a cleaning step using a fluid under high pressure.
  • pile carpet tiles 10 are refurbished.
  • the invention is directed in general to pile carpet, cut or loop, but is primarily directed to carpet tiles since these are used in commercial establishments and generally receive more wear due to traffic by pedestrians thereon and therefore tend to mat and get dirty quicker than residential carpet.
  • the carpet tiles are usually in 45.72 cm (18") squares and have pile yarns, cut or loop, like that shown in US Patent No 4,371,576.
  • the carpet tiles 10 are treated on co-operating conveyors 12 and 14 but, obviously, one continuous conveyor could be used, if desired.
  • a source of high pressure cleaning liquid or water generally designated 16, whereat liquid, such as water, is supplied at a pressure within the range of 13.79-137.9 kNm -2 (200-2000 psig), preferably 20.68-82.74 kNm -2 (300-1200 psig).
  • liquid such as water
  • the liquid is supplied at a pressure of about 55.16 kNm -2 (800 psig) from the nozzles 18 and impinges on the carpet tile.
  • an elongated slot can be used rather than the disclosed nozzles 18 so long as the liquid pressure is maintained in the desired range.
  • the high pressure liquid from the jets clean the dirt from the surface and between the yarn 20 of the carpet tile while at the same time removing the twist from the yarn and causing them to upright themselves.
  • From the high pressure water source 16 the carpet tiles pass under a vacuum extractor 22 to remove water therefrom.
  • Also located under the conveyor 12 is a water sump collector 24 to recover the water from the water source 16.
  • the carpet tiles 10 can be over-printed or brightened by a dye machine 30 prior to being collected on a pallet 32.
  • the dye machine can be of any suitable type but is preferably a computer controlled jet type as that shown and disclosed in US Patent No 4,993,242.
  • the above description is directed to a cut pile carpet but obviously the above system can be employed to clean and de-mat a loop pile carpet tile.
  • One approach includes cutting of the loops in the loop pile product and then treating it as a cut pile carpet tile as described above.
  • Another approach is to pass the loop pile carpet tile under the high pressure water source as described above but pivot the shear 26, as shown, upwards away from the conveyor 14 as it passes downstream.
  • a plurality of slats 34 are connected to the conveyor 12 and/or 14.
  • a chambered guide bar 36 mounted on both sides of the conveyor guides the carpet tile into position under the water source 16 as the slats 34 pass under the guide bars.
  • the slots 34 and the guide bar 36 serve the further function of maintaining the fibres on the edges of the tile in an upright condition as the liquid impinges thereon so that further operations downstream will treat them as well as the other yarn in the body of the tile. This prevents the edge fibres from being bent over and giving a ragged appearance to the carpet tile after cleaning thereof.
  • Fig 2 depicts an overall view of the apparatus to apply high pressure water to the carpet tiles, which is depicted as numeral 16, which is characterized in more detail in Figs 3 and 4.
  • Pump 36 is used to pump, via suitable conduits 38 and 40, a working fluid such as water from a suitable source of supply 42 through an appropriate filter 44 to a high pressure supply duct 46, which in turn supplies water at a suitable dynamic pressure (eg between 13.79 and 137.9 kNm -2 (200 psig and 2000 psig)) to the apparatus 16.
  • a suitable dynamic pressure eg between 13.79 and 137.9 kNm -2 (200 psig and 2000 psig)
  • the high pressure water source 16 is comprised of three basic structures: a high pressure supply gallery assembly 48 (which is mounted in operable association with the high pressure supply duct 46), slotted chamber assembly 50 and clamping assembly 52.
  • Supply assembly 48 constitutes an "L"-shaped member, into one leg of which is machined a uniform notch 56 which extends, uninterrupted, along the entire length of the apparatus 16.
  • a rectangular uniform notch 58 which is in the other vertical leg of the "L"-shaped member 54 and adjacent to the high pressure supply duct 46.
  • a series of uniformly spaced supply passages 60 are drilled through the rectangular uniform notch 58 and extend to the corresponding side wall of notch 56, whereby notch 56 may be supplied with high pressure water from high pressure supply duct 46, the side of which may be milled, drilled, and connected to notch 58 which is along the side wall 62 of the assembly 54.
  • Slotted chamber assembly 50 is comprised of dual elongate "U"-shaped members 63, 65 having a rectangular cross-section therebetween.
  • the upper "U"-shaped member 63 has a series of machined closely spaced slots which form the nozzle 18, each having a width approximately equal to the width of the desired high velocity treatment stream.
  • grooved chamber assembly 50 is positioned, via clamping assembly 52, within supply gallery 54 so that its rectangular cross-section communicates via parallel spaced holes 60 to notch 56 which thereby forms both an upper and lower high pressure distribution reservoirs, respectively, so that fluid enters from a supply duct 46 and then into a high pressure distribution reservoir formed by notch 58.
  • the water then travels via supply passages 60 into a lower high pressure distribution reservoir formed by notch 56 and then goes through holes 70 into an upper high pressure distribution chamber 72 formed by dual elongate "U"-shaped members 63 and 65. Water then flows through slots 18 towards the carpet tile 10.
  • Clamping assembly 52 is provided along its length with jacking screws 78 as well as bolts 80 which serve to securely attach clamping assembly 52 to supply gallery assembly 48.
  • the high pressure water source 16 is connected to the high pressure supply gallery assembly 48 by means of bolts 82 and 84 respectively.
  • bolts 82 and 84 There are a series of bolts 86 which connect the lower "U"-shaped member 65 with the upper "U"-shaped member 63.
  • the means of eliminating dirt and mats from the carpet tiles involves the nozzles 18.
  • the nozzles between one lateral edge of the member 63 are at an angle from the vertical axis of the member 63.
  • the angle deviation from the vertical axis of the member 63 that provides good results is five degrees.
  • This angle can vary widely, with the optimal deviation angle depending on the type of fabric utilized.
