The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

In one embodiment of the present invention, a cleaning member 90 is attached to the surface of a cleaning member attaching part 10. The cleaning member attaching part 10 has a main body 20, a cleaning liquid introduction part 30 extending inside the main body 20, and a plurality of cleaning liquid supply holes 40 communicating with the cleaning liquid introduction part 30. The cleaning liquid introduction part 30 is configured such that cleaning liquid flows in from a first end part 11 side, and an area proportion of the cleaning liquid supply holes 40 in a second region located on a second end part 12 side opposite to the first end part 11 to a surface of the main body 20 is larger than the area proportion of the cleaning liquid supply holes 40 in a first region located on the first end part 11 side to the surface of the main body 20.

A vehicle wash system includes a vehicle treatment area and an overhead frame portion supporting a rotational brush that is translatable relative to a vehicle disposed within the vehicle treatment area. The brush may rotate in the same rotational direction during a first translation direction and a second translation direction of the brush along the vehicle. During one direction of translation, the brush rotates at a first rotational speed, and in the opposite direction of translation, the brush rotates at increased rotational speed. The system may include a pair of side brushes, with the brushes rotating in opposite rotational directions, but maintaining their rotational directions during both directions of translation.

Automatic emitter point cleaners are disclosed. An automatic emitter point cleaning system includes: a fan configured to direct a stream of air through an air path; a point emitter configured to produce at least one of positive ions or negative ions within or proximate to the air path; a brush; a first gear coupled to the brush and configured to move the brush into contact with the point emitter; a second gear to engage the first gear; and a motor to actuate the second gear such that the second gear actuates the first gear to move the brush past the point emitter.

A cleaning brush comprising a carrier and a cleaning unit is provided. The cleaning unit comprises a plurality of cleaning beans set on a surface of the carrier in a spiral arrangement. A spiral coiling around the carrier from an end of the carrier to the other end is formed. A spiral curve path is formed to coil the carrier circumferentially by extendedly arranging the cleaning beans. Hence, the present invention uses the cleaning beans of the cleaning unit to be set on surface of the carrier. On rotating in a fixed direction, the spiral cleaning unit generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream. Thus, dirt can be removed more easily than by using a traditional matrix cleaning device.

The invention relates to a cleaning apparatus (10) for functionally regenerating a brush (20) which can be used for washing a flexographic plate; in particular, the apparatus is configured to regenerate a brush (20) comprising a cylindrical core (5) about which a channel (4) supporting filaments (3) is fixed according to a spiral shape. The apparatus comprises a frame defining a rotation axis (100) for the brush and a motorized assembly, which can be operatively connected to an end of said cylindrical core (5) of the brush (20) to rotate it about the rotation axis (100). The apparatus (10) further comprises a cleaning unit (30) comprising a carriage (31), movable along a rectilinear guide (32) and a tool (33) provided with an end (33A) adapted to penetrate into the spaces defined between the turns of the spiral to detach the polymer and monomer residues hardened in said spaces as a result of the use of said brush for said washing.

A spherical object cleaning system includes a cleaning apparatus for cleaning a spherical object. This cleaning apparatus includes a first member having a first surface, and a second member having a second surface facing the first surface. The first surface and the second surface are sandwiching surfaces sandwiching the spherical object. The first surface and the second surface are configured to be rotatable relative to each other. This cleaning apparatus further includes an introduction portion configured to introduce the spherical object into a space between the first surface and the second surface, and a discharge portion configured to discharge the spherical object from the space. One of the first surface and the second surface is provided with a spiral groove configured to guide the spherical object from the introduction portion to the discharge portion.

A self-cleaning device of the present disclosure includes: a cleaning member configured to clean a cleaning tool that cleans a substrate; and an injection unit configured to inject a liquid toward the cleaning member or the cleaning tool. The cleaning member has a cleaning surface that cleans the cleaning tool when the cleaning tool is pressed thereagainst, and the cleaning surface is inclined with respect to a horizontal plane.

A cleaning tool attachment reduces the amount of foreign matter or cleaning liquid remaining on a workpiece. The cleaning tool attachment includes a housing, a first shaft integrally connectable to a main spindle, a second shaft having an axial direction different from an axial direction of the first shaft, a plurality of tool mounting shafts having an axial direction parallel to the axial direction of the second shaft, a rotation axis conversion gear mechanism arranged in the housing, and a synchronous rotation mechanism arranged in the housing. The synchronous rotation mechanism transmits a driving force of the second shaft to the plurality of tool mounting shafts, and rotates the plurality of tool mounting shafts at the same rotational speed and with synchronous phase angles.

A wire cleaning apparatus and method is provided, in which a wire cleaning apparatus includes a passive brush mechanism comprising a helical brush, the helical structure having a helical axis substantially coincident with path of a wire passing through the wire cleaning apparatus. The helical brush includes a plurality of first bristles generally oriented inwardly from the helical structure toward the wire, and the helical brush may be compressed or extended to adjust the inner diameter of the helical brush. The wire cleaning apparatus further comprises an active brush mechanism disposed around the wire and configured to rotate around the wire. The active brush mechanism comprises at least one cylindrical brush having a plurality of second bristles disposed on a cylindrical surface such that one or more of the plurality of second bristles impinge upon the wire. The at least one cylindrical brush having a cylindrical axis about which the at least one cylindrical brush is configured to rotate relative to the active brush mechanism.
