Definitions

  • the present invention relates to a brush pressure system for a cleaning or sweeping machine particularly such as is used for cleaning or sweeping the floor space of commercial and industrial premises or for example supermarket floors or railway station or airport concourses.
  • Such machines may be so-called pedestrian operated, i.e. Controlled by a pedestrian operator or alternatively may be ride-on machines.
  • WO-A-95/13737 discloses a surface working apparatus in which the employment of the aforementioned floating head system allows for a readily controllable range of operating pressures but which, is compared with the present invention, has a disadvantageously limited range or application pressures particularly towards the lower end of the range.
  • the applicant has now developed a substantial improvement to the control system which allows it to operate more effectively, particularly over low ranges of pressures such as around and below the pressure corresponding to the weight of the brush head itself, and to provide an effective and efficient suspension system which allows for a floating head system over a wide range of pressures.
  • a brush pressure control system for a cleaning, sweeping or scrubbing machine comprising a machine frame supporting:
  • a linkage is provided between the frame and the brush head, and this may be a parallelogram linkage, to keep the brush head suitably and horizontally positioned.
  • means for measuring the wear of the brushes of the brush head and for displaying the wear on an operator console may comprise a potentiometer registering the amount of movement of the balance arm as the actuator raises or lowers the brush head.
  • the potentiometer registers this change as a change in electrical resistance and this is related to the brush wear.
  • brushes typically have a bristle length of 2 inches (4.8cm) when new and can operate effectively even when the bristle length is worn down to only 1 ⁇ 2 inch (1.2cm).
  • the preferred embodiment also provides for a control circuit which is arranged to momentarily pause the actuator at the time at which load sensors register a positive pressure on the brush head, i.e. when the brushes touch the floor.
  • the circuitry measures the position of the potentiometer during this pause and compares it with the previously measured value stored in the circuit and/or to the value measured or preset when the brushes were new, i.e. with calibration values.
  • Electronics such as a microprocessor then uses this information to calculate the relative wear on the brushes and to display the information on a display on the control panel of the machine, e.g.
  • an LED display which may show brush wear as a percentage of either original or remaining bristle length, or indicate a value calculated as corresponding to the actual remaining bristle length or simply provide a high, medium or low indication. At a particularly low value the indicator can be made to flash.
  • the brush assembly comprises two spring tubes 1, containing springs 2.
  • the right hand tube 1 in the Figure is shown in cut-away to illustrate spring 2.
  • Each spring is fixed at one end to the upper end of the tubes at 3 and at the other end to a spring rod 4 which slides through an aperture 5 into the respective spring tube 1.
  • the spring rods 4 are connected together by a bolt 6 and are fixed via assembly 7 to the brush support plate 8 to which brush head or heads 27 are connected.
  • the tubes 1 are prevented from rotating or skewing by a steadying plate 9.
  • An actuator 10 is secured to a bulkhead of a cleaning machine.
  • Actuator 10 drives actuator rod 12 which is shown in substantially closed up position in the Figure.
  • the actuator rod 12 is fixed by a pin 13 to actuator plate 14 which is clamped to both spring tubes 1 by clamping bolts 15.
  • the spring tubes 1 move downwards and the springs 2 are compressed causing a higher pressure to be exerted on the brush head assembly whilst still providing suspension to accommodate uneven floors and brush wear.
  • the effective spring lengths, in an uncompressed state are around 15 inches (38.1cm) and this is particularly suitable for a 26/32 inch (66/81.3cm) brush pressure system.
  • Such an arrangement can provide a range of 0 to 4501b (0 to 204.1 kg) pressure in a loaded pedestrian cleaning machine fitted with apparatus according to the invention, compared to the maximum 2001b (90.7 kg) pressure available using known apparatus.
  • biasing means could be used.
  • a torsion spring has the advantage of taking up less vertical space in a cleaning machine.
  • a torsion spring generally has a low spring rate which is particularly suitable for this purpose.
  • Gas struts or hydraulic or pneumatic systems could also be used.
  • the pressure can be further adjusted by changing the springs for different length ones or different strengths the clamping position of the spring tubes can be altered. However these changes require a service engineer.
  • the system is particularly adjustable since the actuator can be stopped anywhere in its stroke.
  • brush support plate 8 will be attached to a pair of circular or elliptical brushes rotating in a plane generally parallel to the floor (or surface to be cleaned or swept or scrubbed).
  • up to four brushes are in use in some cleaning machines and the apparatus of the invention could be used to control all such four brushes together or alternatively individually (in which case separate actuators would be used for each).
  • a cylindrical brush head could equally easily be controlled mounted on the brush support plate 8 or alternatively controlled at each end of its shaft by respective separate assemblies according to Figure 1.
  • a strain gauged beam 20 which may be used to measure the brush pressure is located under the spring tube clamp plate 18.
  • FIG 2 the brush assembly of Figure 1 is shown mounted in a pedestrian cleaning apparatus. Like parts are indicated by like reference numerals and a pair of spring tubes 1 are attached to actuator rod 12 by actuator plate 14.
  • the actuator 10 is fixed by tie bar 15 to the apparatus frame 16.
  • a second pivoted mounting 17 connects the assembly 7 and brush support plate 8 to frame 16.
  • the brushes themselves are not shown in Figure 2 but are mounted below the support plate 8 behind the protective flange 17 and are driven by scrub brush motors 18 (one of which is shown in Figure 2).
  • Figure 2 also illustrates the relative positions of the water tank or tanks 19, the batter pack 20 for driving the scrub motors 18 together with the transverse drive of the cleaning apparatus.
  • the direction of transverse drive is controlled by a handle 21.
  • a squeegee 22 has suction applied via vacuum motor 23.
  • a brush head pressure control panel 24 is provided within the operator's view.
  • the position of the brush head 27 relative to the floor to be cleaned is controlled by electric or hydraulic actuator 10 lifting or lowering the brush head via an actuator rod which compresses springs in spring tube 1.
  • actuator 10 lifting or lowering the brush head via an actuator rod which compresses springs in spring tube 1.
  • Other resilient means such as a gas strut may be used for applying pressure to the brush head against the floor and of course other means may be used to control the position of the brush head such as hydraulic or pneumatic means. Details of the actuator 10 has been described above.
  • a pressure sensor is located at one of the positions labelled 4 though it may be positioned anywhere in the cylinder or in the arm or in the bottom of the actuator. In use this sensor monitors the pressure applied by the brush to the floor and generates a signal 25.
  • the pressure sensor may be a strain gauge 20 on actuator plate 14 as shown in Figure 1 or a piezoelectric sensor or position sensor.
  • the secure pin (11 in Figure 1) which connects the assembly to the apparatus frame, may be used as a shear gauge to measure pressure.
  • Amplifier 26 converts this pressure signal 25 to a value usable in the subsequent circuitry.
  • the control panel 24 is provided within sight of an operator. It has a pressure select knob 28 by which the operator can pre-select a particular pressure.
  • a rocker switch 29 lifts or lowers the brush head 27 relative to the floor depending on the switch position.
  • a digital display 30 illustrates the pressure of the brush head 27 on the floor, as measured by the pressure sensor.
  • a processor 31 compares the measured pressure signal with the operator selected pressure and generates a control signal accordingly to control (as necessary) the actuator to make the measured pressure substantially the same as the selected pressure.
  • This processor may be of simple construction such as comprising an electronic comparator and amplifier circuit, or it may comprise a standard CPU unit in chip form.
  • Power for the electronic components is supplied by the on-board battery 12 or by alternative low power battery sources.
  • Figure 4 shows the brush head with planetary brushes for scrubbing, cleaning, polishing or sweeping a floor surface mounted via the actuator 10 (only one arm of which is shown) to the machine frame, specifically to the actuator support bracket 30.
  • the brush head is raised and lowered as indicated by arrow 31 by a screw jack-mounted on the actuator 10.
  • the motors for driving the brushes are mounted on the brush head but are not shown in Figure 3.
  • the water tanks for the machine, mounted on the frame, or chassis are also omitted in Figure 3 to more clearly show the other parts of the device.
  • a balance beam 32 is mounted by pivot bearing 33 to one end of a pivot support 34, the other end of which is connected to the frame.
  • the beam 32 is also connected to actuator arm 1 and on the other side of the pivot bearing 33 to a counterweight 35 corresponding to the weight of the brush head.
  • the opposite end of beam 32 is linked to the brush head by a turnbuckle linkage adjuster 36, which is used to adjust the counterbalance for brushes of different length, for example to prevent jamming of the brushes against the floor.
  • a potentiometer 37 for measuring brush wear is connected between the balance beam 32 and the pivot support 34.
  • a drive wheel 39 for the machine is shown: usually one such wheel is positioned at each corner of the chassis or frame.
  • the path of movement of the counterweight is shown in dotted outline, as the brushes are raised by the lower line and as they are lowered by the upper line.
  • the balance beam 32 rotates about pivot bearing 33 and the counterweight 35 swings upwardly.
  • the change in position of the balance beam 32 causes a corresponding change in the position of the wiper of the potentiometer and 37 thus the measured resistance changes.
  • a load sensor (not shown in Figure 4) detects the position at which the brushes touch the floor, i.e. a positive pressure is registered and pauses the actuator momentarily for the potentiometer measurement at that position to be recorded.
  • the actuator then continues to drive the brush head down onto the floor until the desired pressure on the floor is attained.
  • the counterweight counteracts the weight of the brush head and allows a very low range of brush pressures to be selected, much lower than was hitherto attainable, for example less than 100lbs/in 2 (70.3 g/cm 2 ). This range is used for light cleaning or polishing or for cleaning fragile or specialist floor surfaces.
  • Comparison of readings on the potentiometer as the brushes contact the floor is a measure of the amount of wear on the brushes and can be used to provide an indication of such on a display panel of the operator's console.

Abstract

Cette invention concerne un dispositif de régulation de la pression de la brosse d'une machine à nettoyer, balayer ou récurer comportant un bâti de support d'une tête de brossage (8), un actionneur (10), fixé entre le bâti et la tête de brossage, qui permet de lever ou d'abaisser la tête de brossage, un balancier allongé (32) fixé au bâti (30) de manière à pouvoir pivoter et relié à une extrémité de l'actionneur de façon à pouvoir bouger avec celui-ci, et pourvu en son autre extrémité d'un contrepoids (35). Le dispositif (24) de régulation de la pression est particulièrement utile aux machines actionnées par un opérateur en position debout mais peut également convenir aux machines sur lesquelles l'opérateur est monté. Le perfectionnement permet au système de fonctionner plus efficacement en particulier dans une gamme de pressions peu élevées telles que celle correspondant au poids de la brosse seule et il permet en outre d'utiliser un dispositif à tête flottante avec une gamme étendue de pressions. Le contrepoids (35) correspond avantageusement au poids de la tête de brossage (8) et on peut équiper le dispositif d'une articulation en parallélogramme (38) entre le bâti et la tête de brossage de façon à maintenir la tête de brossage dans une position généralement horizontale. Un potentiomètre peut enregistrer le déplacement du balancier lorsque la tête de brossage est soulevée ou abaissée de manière à fournir une indication relative à l'usure de la brosse.
