Abstract
A conveyor for moving successively a plurality of articles, typically cards, in flat horizontal position, longitudinally along a horizontal bed, comprises a plurality of chamfered rollers rotating at uniform speed on vertical axes, disposed in two laterally spaced lines extending along the bed, with the rollers of each line rotating in a direction opposite to that of the rollers of the other line, all the rollers making propelling contact with the edge margins of the cards, and all mounted in modules adapted to be spliced endwise to each other, and all geared together in groups individually driven directly by a single power source.
Claims8
A conveyor for moving a plurality of articles including cards successively in flat horizontal position comprising
- a plurality of supporting structures each comprising an inverted channel the web of which provides a longitudinally elongated bed,
- a plurality of rollers mounted in each supporting structure along said bed for rotation on vertical axes in two longitudinally extending lines laterally spaced apart,
- each roller having a peripherally chamfered end portion and an axially spaced drive-receiving portion,
- power means including an electric motor carried by each supporting structure connected to the drive-receiving portions of the rollers for rotating the rollers of the two lines in opposite directions,
- whereby each supporting structure and its supported elements comprise a complete conveyor module,
- means splicing the modules endwise to each other to form a continuous conveyor,
- gearing traversing said splicing means connecting the rollers of contiguous modules to each other for insuring uniform rotation of all the rollers of the conveyor,
- said splicing means comprising a short upright channel having its upturned flanges bolted to the downturned flanges of adjacent supporting structure channels, and
- legs having their tops bearing the webs of the splicing means channels, thereby supporting the entire conveyor,
- whereby rotation of the rollers causes cards having their longitudinal edge margins seated in the chamfers of the rollers to be propelled along the bed.
A conveyor for moving a plurality of articles including cards successively in flat horizontal position comprising
- a supporting structure providing a longitudinally elongated bed,
- a plurality of rollers mounted in said supporting structure along said bed for rotation on vertical axes in two longitudinally extending lines laterally spaced apart,
- each roller having a peripherally chamfered end portion and an axially spaced drive-receiving gear,
- a plurality of idler pinions pintled in the supporting structure adjacent to each of said longitudinal lines,
- each idler pinion being meshed with two adjacent gears in the line,
- power means comprising an electric motor having a drive shaft carried by the supporting structure,
- first drive gearing connecting said motor drive shaft with a roller gear in one of said lines for rotation in one direction, and
- second drive gearing connecting said motor drive shaft with a roller gear in the other of said lines for rotation in the opposite direction,
- whereby rotation of the rollers causes cards having their longitudinal edge margins seated in the chamfers of the rollers to be propelled along the bed.
A conveyor for moving a plurality of articles including cards successively in flat horizontal position comprising
- a supporting structure providing a longitudinally elongated bed,
- a plurality of rollers mounted in said supporting structure along said bed for rotation on vertical axes in two longitudinally extending lines laterally spaced apart,
- each roller having a peripherally chamfered end portion and an axially spaced drive-receiving pulley,
- an endless belt trained over the sides of the pulleys in both lines to rotate the pulleys of the lines in opposite directions,
- power means comprising an electric motor having a drive shaft carried by the supporting structure, and
- transmission means connecting the motor to said pulleys,
- whereby rotation of the rollers causes cards having their longitudinal edge margins seated in the chamfers of the rollers to be propelled along the bed.
- the drive-receiving rollers of an aliquot number of the rollers in each line being connected together to form a single train of rollers to rotate in the same direction,
- an electric motor carried by the supporting structure,
- and transmission means connecting the motor to said trains for rotating the rollers of the two lines in opposite directions to move said cards along the bed,
- said transmission means comprising a direct drive from said motor output to the center of each train for driving an equal number of rollers in each direction along the bed.
A conveyor for moving a plurality of cards successively in flat horizontal position comprising
- a supporting structure providing a longitudinally elongated bed,
- a plurality of rollers mounted in said supporting structure along said bed for rotation on vertical axes in two longitudinally extending lines laterally spaced apart,
- said rollers having upper end portions adapted to engage the side edges of cards to be moved along the bed, and having drive-receiving lower end portions,
