An image forming apparatus includes a density sensing portion, a cleaning portion, and a control portion. The density sensing portion includes a substrate and a sensor package and outputs a sensing value related to a toner density of a toner image formed on an outer circumferential surface of an image carrier. The control portion performs control so that, when the cleaning portion performs cleaning of a sensing surface, a brush is moved to a cleaning position where the brush contacts the sensing surface. The control portion also performs control so that, when the cleaning portion does not perform the cleaning of the sensing surface, the brush is moved to a retracted position where the brush does not contact the sensor package and the substrate.

A cleaning device cleans a surface of a sheet conveyance member which conveys a sheet in an image forming apparatus that executes image forming processing using a recording material, the surface carrying a solid substance that originates from the recording material and that adheres to the surface. The cleaning device includes a cleaning member including a contact surface configured to come in contact with the surface of the sheet conveyance member. The contact surface is an irregular surface rougher than the surface of the sheet conveyance member. At cleaning of the surface, the cleaning member makes a relative movement to the surface of the sheet conveyance member. The irregular surface is an irregular surface configured to take away the solid substance adhering to the surface of the sheet conveyance member when the cleaning member makes the relative movement.

A cleaning device includes a separation and contact mechanism that separates a web from a conveyance roller and brings the web into contact with the conveyance roller, and a controller. The controller includes a conveyed sheet number determination unit and a separation and contact control unit. The conveyed sheet number determination unit monitors a conveyed sheet number of both-surface image forming sheets where image forming processing is applied to both a first surface and a second surface with respect to the sheets conveyed by the conveyance roller, and determines whether or not a cumulative value of the conveyed sheet number has reached a predetermined threshold value. The separation and contact control unit controls the separation and contact mechanism so as to allow the web to be pressed to the conveyance roller by a pressing roller when the cumulative value of the conveyed sheet number has reached the threshold value.

A cleaning device includes a cleaning unit, a movement mechanism, and a positioning portion. The cleaning unit includes a cleaning part that has a contact surface extending along an axial direction of a conveyance roller and cleans the conveyance roller, and a cleaning housing that supports the cleaning part. The movement mechanism moves the cleaning unit between a cleaning position and a mounting and removing position. The movement mechanism allows the cleaning part to be brought into contact with the conveyance roller at the cleaning position, allows the cleaning part to be disposed below the conveyance roller in a separated manner at the mounting and removing position and allows the cleaning unit to be mounted on or removed from the apparatus body. The positioning portion restricts a relative position between the cleaning part and the conveyance roller by being brought into contact with the cleaning unit.

The cleaning device includes a cleaning unit. The cleaning unit includes a cleaning part having a contact surface brought into contact with a surface of a conveyance roller to clean the surface of the conveyance roller, and a housing that supports the cleaning part. The cleaning part includes a web of a strip shape, the web forming the contact surface that comes in contact with the conveyance roller, a pressing roller that presses the web against the conveyance roller, a feed-out roller that feeds out the web so as to cause a part of the web that comes in contact with the conveyance roller to shift, and a take-up roller that takes up the web. The housing has an opening that receives foreign matter dropping from the vicinity of a nip portion formed between the pressing roller and the conveyance roller.

A delivery head for a dispensing machine for delivering fluid products, including: a tubular casing having a vertical longitudinal axis, a plurality of nozzles carried by the tubular casing and having respective outlet openings with axes parallel to the vertical longitudinal axis, and a cleaning device for automatically cleaning the nozzles, having a plurality of scraper tubes associated with respective nozzles, movable in the a direction of the vertical longitudinal axis between a raised position and a lowered position, and vice versa, and having respective lower ends that clean the nozzles during a stroke from the raised position to the lowered position.

A cleaning device includes a cleaning unit and a movement mechanism. The cleaning unit includes: a cleaning part that has a contact surface extending along an axial direction of the conveyance roller and cleans the surface of the conveyance roller by bringing the contact surface into contact with the surface of the conveyance roller from below, and a cleaning housing that supports the cleaning part. The movement mechanism moves the cleaning unit between a cleaning position and a mounting and removing position below the cleaning position. The movement mechanism allows the cleaning part to be brought into contact with the conveyance roller at the cleaning position, allows the cleaning part to be disposed below the conveyance roller in a separated manner at the mounting and removing position and allows the cleaning unit to be mounted on or to be removed from an apparatus body.

A cleaning system for a solar panel is provided. The cleaning system comprises: i) a frame moveable in a transverse direction over the solar panel, the frame having edges oriented in the transverse direction; a brush assembly positioned within the frame and moveable in a longitudinal direction including a plurality brush holders arranged within the frame, with each brush holder being adapted to interchangeably receive a brush for cleaning the solar panel; and a liquid spray arrangement including nozzles arranged one or more rows for spraying at least one of water and a water detergent mix onto the solar panel. The liquid spray arrangement includes nozzles positioned near at least one of the transverse edges of the frame for spraying the water detergent mix onto a longitudinal end of the brush assembly.

The present invention is an automated wind turbine servicing system that includes a rover, and uses an active electro-mechanical gripping roller system to attach to the horizontally positioned airfoil and navigate along it in order to clean, inspect, service (paint, remove material or repair), or otherwise maintain the wind turbine airfoil. An electromechanical compression system adapts to various turbine airfoil profiles so that it can be used to service many different types of wind turbines. The rover operates on a horizontal airfoil rather than a vertical airfoil to utilize gravity and prevent movement along the chord of the airfoil. Once secured to the airfoil, the rover activates a drive system that propels the rover along the airfoil as it travels along the upper edge, using wind pressure, the rover wheels' frictional adherence to the airfoil, and gravity to assist in coupling the rover to the airfoil. The rover, which preferably includes a robotic arm, is able to utilize multiple tools to perform various tasks such as inspecting, cleaning, sanding, repairing, painting and laying leading edge protection tape as well as vortex generators on the surface of the airfoil.
