  • Patent number: 10441977
    Abstract: Separation and classification equipment for separating a mixed waste stream into first, second and third fractions. The equipment comprises a feeding member for feeding the waste stream toward a gap and a blower for discharging a stream of air for mixing with the waste stream, as the waste stream falls through the gap. The first fraction falls through the stream of air and collects in a first collection area while the stream of air carries away the second and the third fractions. A rotatable permeable member is arranged to permit the stream of air to pass therethrough and thereby force and retain the third fraction against a surface of the rotatable permeable member and be conveyed, by the rotatable permeable member, toward a third collection area while the second fraction tends to separate, from the rotatable permeable member and the third fraction, and collect in a separate second collection area.

  • Patent number: 9527673
    Abstract: A spiral conveyor and a method for taking up slack in a modular conveyor belt traveling a helical path. The spiral conveyor includes a rotating cylindrical drive drum with parallel drive members extending from the bottom to the top of the drum on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the drum for engaging the inside edges of the belt. A motor-driven take-up shaft and shaft-mounted sprocket set takes up slack in the belt after its release from the drum. To control tension at the discharge of the belt from the drive drum, the take-up motor is normally operated in a closed-loop control mode, but switches to an open-loop constant-speed control mode when the take-up motor stalls.

    Abstract: The present invention provides a plate member conveying apparatus configured such that an occupied area is small, and a plate member is unlikely to be damaged. A plate member conveying apparatus according to the present invention includes a feed device having a conveying portion and a pressurizing portion. The conveying portion includes a belt configured to contact one of surfaces of a plate member in a vertical state to feed the plate member in a conveying direction. The pressurizing portion applies pressure of a fluid to the other surface of the plate member in the vertical state in a direction perpendicular to the surface of the plate member to press the plate member toward the belt. Then, the plate member in the vertical state is conveyed while being held by sandwiching the plate member between the belt of the conveying portion and the fluid of the pressurizing portion.

    Abstract: A pretreated-cardboard stripper that obtains a cardboard item and strips or blanks the cardboard item using laser cutting, die cutting or other techniques. The cardboard item may be a single item or multiple sections that are jointed together. After stripping or blanking, the stripper operates to sort the sections and joints from the waste by a vacuum sorter. The vacuum sorter includes a vacuum chamber with openings along its surface or certain areas of the surface and a peeler. After stripping, the pre-treated cardboard is transferred by the peeler along the surface of the vacuum chamber. The waste of the cardboard (areas between the sections and joints) may be coupled to the vacuum chamber surface while the pre-treated cardboard is being transferred by the peeler along the surface of the vacuum chamber, which has the advantage of operating to disconnect and thus sort the waste from the sections.

    Abstract: A belt conveyor with a surface layer transferred onto its article-carrying or other surface to impart certain effective properties to the surface. The belt conveyor comprises a conveyor belt driven by a belt drive along a belt-conveying path. A transfer element transfers a coating material to a belt surface along a section of the belt-conveying path. Metallic bearing surfaces in contact with the belt surface act as transfer elements from which an oxidizable metal is rubbed by the relative motion of the belt to form a high-friction metallic oxide layer on the belt surface. Another transfer element is realized by an applicator with a reservoir for storing a coating material. The applicator is positioned close to the belt surface to dispense a layer of coating material with properties that mask the inherent surface properties of the belt. In yet another version, the conveyed articles themselves serve as transfer elements.

    Abstract: A process for forming a glass sheet, which is a process for continuously forming a glass sheet, and which comprises a step of introducing a vapor film-forming agent, which is not vapor at least around room temperature and which is vapor at a temperature above the glass transition point of the glass, into a support composed of a structure or a material capable of internally containing liquid, and a step of sliding the support and the glass of which temperature is above the glass transition point against each other via a thin layer of a vaporized vapor film-forming agent.

  • Patent number: 6290453
    Abstract: A unit for feeding flat diecut blanks of wrapping material to a user machine is equipped with a conveyor by which blanks disposed on edge transversely to a given feed direction and ordered in a substantially continuous column are caused to advance along a conveying path extending toward a transfer station where each blank in turn is picked up from the column; the conveyor comprises two sections aligned along the path: the one, an intermittently driven first belt by which the column is advanced toward the transfer station through a step of predetermined length, at a predetermined frequency timed with the operation of a pickup mechanism positioned at the transfer station, the other a continuously driven second belt designed to advance the column toward the first belt at a predetermined velocity.

  • Patent number: 6250472
    Abstract: The present invention includes devices and methods for handling and sorting paper. Devices for accelerating and spreading paper from a paper input to a sensor are disclosed. Operably thin layers of paper are passed through a sensor at cost effective feed rates. One embodiment of the invention includes a spreader positioned to receive paper from the input and an inclined feed section downstream of the spreader. The inclined feed section includes first and second inclined conveyors to further accelerate and spread the paper. A feed accelerator is operably positioned to receive paper from the second inclined conveyor. The feed accelerator further accelerates and separates the paper. The feed accelerator feeds the paper to the sensor which is operably connected to an ejector downstream of the sensor. Targeted paper is ejected from the paper stream and product paper continues downstream to a product conveyor.
