Abstract:
Disclosed is a paper feeding device (10) comprising a storage surface (14) for a stack of papers (12), with a leading edge (14a), a trailing edge (14b), and a first and a second side edge (14c, 14d). The surface (14) is adapted to be moved vertically. The device further comprises a vacuum feeder (16) for feeding papers from their position on the storage surface(14) and imparting on an uppermost sheet of paper (12a) a horizontal displacement, and a blower arrangement (18, 20) adapted to provide a curtain of air separating the uppermost sheet of paper (12a) from the rest of the stack of papers. The blower arrangement comprises side blower units (18) adapted to provide an air flow directed towards the leading edge (14a) of the storage surface (14).
Abstract:
A paper feeding device (10) comprises a storage surface (14) for a stack of papers (12) and being adapted to be move vertically between a first, lower end position and a second, upper end position, and a feeding roll (16) for feeding papers from their position on the storage surface (14) and imparting an uppermost sheet of paper (12a) a horizontal displacement. A first mounting device (20) comprises a first vertically movable, preferably pivotable housing (22) adapted to mount or suspend a first end of the feeding roll (16), and a second mounting device (40) comprises a second vertically movable, preferably pivotable housing (42) adapted to mount or suspend a second end of the feeding roll (16) opposite to the first end of the feeding roll. By providing the first and second housings pivotable independently of each other and an intermediate axle (26), the feeding roll adapts to a non-uniform stack of papers, improving the reliability of the feeding.
Abstract:
A sheet feeding roller (101) which feeds a sheet S stacked on a sheet supporting plate (110) capable of being lifted and lowered is swingably supported at a swing end of a sheet feeding roller supporting arm (104) which is arranged swingablyin an up-and-down direction and a roller biasing member (103) applies a force to the sheet feeding roller supporting arm (104) in a direction that the sheet feeding roller (101) is pressed to sheets S stacked on a sheet stack tray (61). A swing fulcrum (104a) is arranged in arange between a tangential line of the sheet feeding roller (101) at the upstreammost pressing position against the sheet feeding direction and a tangential line of the sheet feeding roller (101) at the downstreammost pressing position out of pressing positions where the sheet feeding roller (101) is pressed to the sheets as being varied inaccordance with a sheet stacking state of the sheets.
Abstract:
Настоящее изобретение относится к системам выдачи торговых автоматов. Устройство предназначено для выдачи товара или элемента товара в качестве приложения к покупке, например, выдача упаковки. Технический результат состоит в простоте конструкции устройства, возможности выдачи пользователю товара или элемента товара, как приложение к товару любой формы, в т.ч. отличной от формы товара, реализуемого в торговом автомате. Заявленный технический результат достигается за счет того, что система выдачи в торговом автомате товара или приложения к товару состоит из вращающегося элемента произвольной геометрической формы, выполненного с возможностью сдвигать товар и/или отдельные элементы товара внутри торгового автомата или для выдачи пользователю исключительно за счёт силы трения, возникающей между внешней поверхностью барабана и поверхностью товара и/или отдельных элементов товара.
Abstract:
In one embodiment of the present invention, an apparatus for lifting an object includes a rotational axis (59) that has a first lead screw (520) threaded in a first direction, a second lead screw (524) threaded in a second direction, and a coupler (522) that couples the first lead screw (520) and the second lead screw (524). A first lifting arm (506) has first and second members that move in a first plane that is substantially parallel to the rotational axis, and a second lifting arm (514) has first and second members that move in a second plane that is substantially parallel to the rotational axis. A first transverse member (532) is coupled to the first lead screw (520), and a second transverse member (540) is coupled to the second lead screw (524). Rotation of the rotational axis (519) in a first direction raises the first (506) and second lifting arms (514), and rotation of the rotational axis in a second direction lowers the first and second lifting arms.
Abstract:
The sheet capacity of a pivoting feed head is combined with a complimentary pivoting design for the paper tray lift, such that a large total capacity of sheets is attained within a compact space, while allowing the lifting mechanisms to be located outside of the perimeter of the paper tray.
Abstract:
In an example implementation, an example printer system includes a lift, an indicator, a trigger, and a reset mechanism. In an example implementation, a lift is orientable by an amount of media when adjacent to the lift and a trigger has a first portion engageable with the lift at a first orientation of the lift. In an example implementation, the trigger causes the indicator to move towards a first location relative to an aperture defined by an exterior surface in response to engagement with the lift. In an example, the reset mechanism has a first portion engageable with the lift at a second orientation of the lift and the reset mechanism causes movement of the indicator away from the first location in response to engagement with the lift.
