DEVICE FOR WASHING OF CARPETS
Tlle object of the invention is a device for washing of carpets, in particular Eibre carpets, to which device belong rolls, supported on which the carpet is arranged to be conveyed within the device, to which rolls belong a supporting roll to support the carpet during the washing process and a rinsing roll, located at a distance from the supporting roll, to support the carpet during the rinsing process.
To the carpets made of ar~ificial and natural fibres belong a relatively stiff bottom layer made of rubber or corres-ponding material and a fibre layer fixed to the bottom layer. These carpets cannot be washed in normal washing machines due to their stiff bottom structure. The problem is the washing of the big carpets efficiently and at low costs. Nowadays the carpets are generally washed by hand using auxiliary equipment, whereby the costs are high.
Washing contrivances have been developed, in which the carpets are cleaned through conveying them supported on rolls e.g. in different kinds of washing basins and by br~lshing them during the process in order to remove the dirt. The brushing, however, wears and tears to a great extent the carpets and the time of usage for them is shortened. With the help of the present washing devices the carpets cannot be washed efficiently.
The aim of thè invention is to bring forth a washing device, which eliminates the disadvantages in the present washing contrivances for carpets. In particular the aim with the invention is to bring forward a device for the washing of carpets, by means of which the carpets made of artifi-cial and natural fibres can be washed efEiciently and at low costs. The aim of the invention is additionally to bring forth a device for washing of the carpets, which is easy to use and dependable in operation.
~ZS~380 The aim of the invention is reached by means oE the deviee, which mainly is characterized in that, what in presented in claims.
In the device according to the invention between the supporting roll and the rinsing roll a washing and rinsing apparatus is placed, which is arranged to flush under pressure being liquid detergent on the surface of the earpet loeated on the supporting roll and liquid scavenging agent on the surface of the carpet loeated on the rinsing roll. Hereby the earpet is washed efficiently, because the detergent and the scavenging agent can be flushed on the surface of the earpet at a high pressure, favourably at a pressure of 100 kp/cm , whereby an effieient eleaning aetion is reached. The device is simple and efficient and the pressure of the detergent and scavenging agent flushes can be regulated to conform with the dirtness and the quality of the earpet. The washing and the rinsing apparatus being loeated elose to the supporting and rinsing rolls the jets are pointed at the earpet eonveyed between the rolls. The earpet is in a bent position, whereby the gaps between the fibres are opened and a good eleaning effeet is aehieved. In addition eomes, that the deviee in aeeordance with the invention is simple to manufaeture and to operate.
In the following the invention is explained in detail by referring to the attached drawing, whieh illustrates a deviee in one application of the invention BRIEF DESCRIPTION OF THE Rl~WING5 Fig. 1 is a schematie side elevationa] view, partly in eross-seetion and partly broken away for clarity, illustra~ing a device for washing earpets formed in aeeordance with the present invention;

Fig. 2 is a schematic perspective view illustrating a device for washing carpets formed in accordance with the present invention mounted in a carpet wasning apparatus;
Fig. 3 (with Fig. 1) is a schematic side elevational view showing the placement of rolls in accordance with the present invention and the direction of feed of the carpet therethrough;
Fig. 4 is a perspective schematic view, partly broken away or clarity of a tubular contrivance having several jets formed in accordance with the presen-t invention; and Fig. 5 is a schematic side elevational view, partly in cross-section, illustrating the washing and rinsing apparatus in relation to the supporting roll and rinsing roll of the present inventionO
To the application illustrated in the picture belongs a feeding roll 1 placed in the front part of the device for the purpose of feeding the carpet into the device, a next to the feeding roll placed supporting roll 2 to support the carpet during the washing, an at a distance from the 2n supporting roll placed turning roll 3, an at a distance from the turning roll and close to the supporting roll placed rinsing roll 4 to support the carpet during the rinsing and the next to the rinsing roll movable placed drying roll 5 for drying of the carpet. The rolls are preferably mounted within an apparatus as shown for example in Fig. 2. The carpet is fed into the device with the side to be washed downwards and is directed by adjustable guiding supports (not visible in Fig. 1) from the feeding roll to the supporting roll and from there over the turning roll to the rinsing roll, from where the carpet is directed through the drying roll out of the device (see Figs. 1 and 3). In the application presented ~2S~33~
the feeding roll~ the supporting roll, the rinsing roll and the drying roll are located mainly in the sa~e line at a short distance from the adjacent rolls. The turning roll is placed at a distance from the supporting roll and the rinsing roll outside the line formed by the rolls. The rolls can of course in other applications be placed in some other way, whereby e.g. the distances between the rolls may vary.
To the device illustrated on the picture belongs a washing and rinsing apparatus 6 placed between the supporting roll and the rinsing roll. To the washing and rinsing apparatus belongs in the presented application the body 6, which is arranged movable in the cross direction in regard of the rolls and the carpet. To the apparatus belongs the partition wall 11 placed between the supporting roll and the rinsing roll and the body 6 is arranged to be movable supported on the partition wall resting on a support made in the lower part of the partition wall. The washing and rinsing apparatus is moved back and forth in the cross direction and the motion direction of the apparatus is changed at the turning points, which are adjustable according to the width of the carpet, in a known way by means of difEerent width tracers.
As can be seen in Fiys. 4 and 5, for example jets 7 and 8, are located on both sides of the washing and rinsing apparatus and pointed at the supporting roll and the rinsing roll. To the apparatus hoses are led, by means which from the jets 7 the deteryent on the surface oE the carpet to be cleaned and from the jets 8 the scavenging agent on the surface of the carpet is flushed. The pressure of the jet flush is steplessly adjustable and the pressure being over 100 kp/cm~ the carpet is cleaned efficiently.
~'~S838 5-~
When feeding the dirty carpet into the device the carpet is washed by means of the washing je'cs in a bent position supported by the supporting roll, whereby the raising tracks between the fibres are opened and the carpet is efficiently cleaned (see Figs. 1 and 3 and 5 in particular). With the help of the turning roll the carpet is turned in such a way, that at the rinsing roll the fibre surface of the carpet is in the direction to the rinsing jets. The scavenging agent flushed from the rinsing jets is washing the detergent efficiently away.
To the device belongs further a drying contrivance 9 placed close to the drying roll for drying of the carpet coming from the rolls. The drying contrivance can be compressed air operated or eOg. a suction drier. The drying contriv-ance makes the action of the drying roll more efficient and it is not necessary from the point of view of the operation of the device.
In a second application to the device in accordance with the invention belongs a detergent basin 12 located near the feeding roll, whereat the carpet to be cleaned is arranged to be transferred through the detergent basin prior to the supporting roll. Particularly when washing very dirty carpets this kind of a pre-washing and soaking is necessary.
The form and function of the washing and rinsing apparatus can vary in other applications of the invention~ The washing and rinsing apparatus is in an application of the invention arranged to extend tubeformed (Figs. ~ and 5) in the cross direction of the carpet for the width of the carpet and the rolls, for example along element 13. In this case to the apparatus belong several, at a distance from each other placed jets on both sides of the body. In ~S~3380 5a this application as well as in the earlier presented applications the washing and rinsing apparatus is located between the supporting roll and the rinsing roll mainly at an equally long distance from the rolls.
In one application of the invention the jet or the jets are arranged in a known way revolving in regard of their a~es, whereby an equal dispersion of the liquid is achieved and as a consequence of this a more uniform washing result.
The invention is not limited to the presented applications, but it can vary within the range of the claims.
