Carpet tamping machine

The invention relates to a device for the mechanical cleaning of carpets.

Carpet tamping is an unpleasant cleaning step due to dust and pregnancy, but there is no market available for the machine tumbling of household rugs. WO 01/93739 AI deals with industrial carpet cleaning but is not applicable to cleaning small individual carpets. The device according to ES 2016512 is intended for cleaning car mats. The need for them is slightly different than for ordinary household rugs. This machine focuses on machine-brushing the carpet and has the effect of manual tamping. Especially for rotary brushes, long fibrous debris such as hair and animal hair is trapped in the brush. In this case, brushes must be cleaned frequently, especially before cleaning delicate carpets. In addition, a wet brush will pick up a variety of dirt, and if the brush itself is not thoroughly cleaned continuously, highly discolored water-soluble contaminants may copy the color defects every ... round on the carpet. For example, in an ES 2016512 "·: brush, the brush is not cleaned except by '' spraying the water from which the water flows to the same place as the treated carpet.

The object of the invention is a mechanical carpet cleaning machine which is both simple and easy to use and furthermore the cleaning is carried out in a closed and ventilated interior of the machine, whereby '·' · makes sense in common areas of, for example, This is possible with the device according to the invention, since cleaning requires only the user to start the machine, place the mat on the inlet and light braking during the cleaning. It is also possible to fit 2 114993 fans, which automatically takes care of the cleanliness of the entire working environment. Heavier debris that does not escape due to ventilation can be removed from the unit via a bottom hatch. In addition, the bottom can be shaped like a funnel and arranged on the bottom of the funnel with a Vacuum Cleaner, so that the average user does not have to worry about a dirt problem other than removing debris that has fallen during the carpet importing and feeding step. The property's cleaner will clean the fan and vacuum filters at regular intervals. However, this automatic debris removal from the bottom of the device is, in a way, an additional feature to the actual killing and increases the cost of purchasing and operating the device.

A version of the device according to the invention will now be described with reference to the accompanying drawings. As regards the features of the invention, reference is made to the claims.

Fig. 1 illustrates the principle of a cleaning operation in which carpet 1 passes along a support grate 2 in direction A and simultaneously rotates the main axis 3 in a mechanical direction underneath the grid. The main axis 3 is provided with tamping elements 4 having: or tangent arc. At the moment shown in Figure 1, the rollers 5 do not support the mat 1, but the one on the left is approaching it. By adapting the main axis • »

\ 3 radius of rotation, tangent arc C, and tangent arc C

distance of the highest point from the upper surface of the grid 2 to a suitable mutual relationship, the stroke rate of roll 5 relative to the mat 1 is obtained to correspond to manual trapping, i.e. local and instantaneous acceleration of roll 5 resulting from manual trapping is obtained. In a stroke arranged in this manner, the tip 5 travels several · centimeters along the surface of the carpet 1 during each stroke. If the tip of the tamping element 4 is fixed relative to the main axis 3 it causes excessive wear on the mat 1 due to friction and 114993 3 at the same time tends to move the mat 1 too fast in direction A through the device; 1 and therefore does not cause substantial wear. At the same time, the traction in direction A is reduced to a suitable light feed for passing the mat 1 through the device. In principle, roller 5 could be a narrow circular brush that freely rotates the carpet quite efficiently, but especially in devices intended for shared use, the problem of transferring hairs and hair from one brush to another becomes problematic. To be effective, the acceleration caused by the impact of the roller 5 on the carpet 1 is so great that the carpet 1 cannot return to the grate 2 by the action of the earth alone, and not even! on the tangent arc C, before the next roll 5 comes up from the grille 2, but the next stroke passes, and in the subsequent stroke, the carpet 1 is only slightly inside the tangent arc C, so that the carpet 1 appears to float above the colored tips 5.

To overcome this problem, resilient stops 6 are placed above the tangential arc C, which return the carpet 1 close to the grate 2 before the next stroke.

; * Figure 2 shows the situation of Figure 1 with the main axis rotated '90 °. Carpet 1 has struck the elastic stops. The elastic stop 6 may be, for example, a long-brushed brush or a rubber sheet of about 2mm thick and about 30-70mm high. The problem with the brush is again * · "'that it retains in itself dirt that comes off occasionally, so the rubber plate gives a smoother finish. The carpet 1 can also be prevented from swinging with a lid close enough to the tangent arc C.

; . Figure 3 shows the cleaning of the working environment. It has a tamping element according to Fig. 1 · positioned inside the housing 10 so that the cover 11 covers the entire tamping event, but 114993 4 allows the carpet to pass from the slot 12 into the device and from the slot 13. The lower surface is closed by a sliding door 14 for removing debris, this open door is indicated by a dashed line. The fan, which is not shown in the figure, is removed come off the fine dust rejected by beating the upper surface of the mat 1 through the suction opening 15 in accordance with the arrow D. This creates a vacuum inside the device. The replacement air enters the device as shown by the arrows E through the carpet passages 12 and 13, so that no dust enters the work space. For cold seasons, some of the ventilation air can be returned to the inside of the machine after the dust has been removed. This takes place preferably in the direction of arrow E to the mat above the one, and on the opposite side of the suction device, wherein the dust transfer is enhanced leveidenkin a top inlet with the mats. When the home carpets has once tapped, opens the door 14 and brush debris from the trough in the direction of the arrow F in the trash. At this point, brushing does not substantially raise the dust because of the i! During the ventilation, the finest dust has been removed and the debris and the remaining dust are partially bound to each other. From an environmental point of view, this is a quite functional entity compared to handheld outdoor killing, since in outdoor killing, a small amount of almost invisible fine dust is transported over a large area along with the wind, and larger dust and coarse debris remain in the immediate vicinity of the killing site. The swab itself is essentially airborne • 'and finally the whole area remains dirty.

'·' In the device according to the invention, coarse dust and debris are easily trapped within the machine on a tray 14 and · '; is disposable, and the smallest amount of fine dust is removed from the inside of the device through the suction openings 15 through the ventilation air either out or ·., depending on the conditions, allowing the operator to work in the fresh air and the carpet to be ventilated. The filter is not shown in the figure.

To demonstrate the simplicity of operation, the hardware option shown in Figure 3 according to the invention can be done! The following is a summary: The user only needs to turn the unit on by pressing button 16, whereupon the tamping unit will start to rotate and the ventilation will start and remain active. The mats are then fed one by one from aperture 12 and lightly braked, depending on the dirtiness of the carpet, and the cleaned carpets are rolled out for removal. Finally, the device is stopped by the button 17. The bottom hatch 14 is opened dotted line position shown in Figure 3 and sweeping debris from the trough formed by the door in accordance with the arrow F. The door 14 is finally closed, leaving the device ready for the next user.
