Description
Technical field
The present invention relates to a kind of sheet feeding unit, sheet feeding-device and imaging device, more than ground of paper that are used for trending towards clinging are mutually supplied with.
Background technology
For example in duplicating machine and the printer, the cutting paper that can supply with continuously is confined to the high-quality paper and the normal paper of copier manufacturer appointment usually at imaging device.Separate and supply with this paper for many, used various friction isolation technics, for example postpone roller isolation technics and separating pad technology.
To introduce below and postpone the roller isolation technics.Pick-up roller contacts with the top side paper of paper buttress.Donor rollers along paper feeding to the downstream that is arranged in pick-up roller.Separate roller contacts with donor rollers, and along being driven with predetermined torque in the opposite direction with paper feeding.In the paper of sending by pick-up roller, have only a piece of paper to pass through folder district between donor rollers and separate roller.Thereby prevent double supply.
In the separating pad technology, friction means presses donor rollers with predetermined pressure, and has only a piece of paper to pass through folder district between them, thereby prevents double supply.
For example, under the situation that postpones the roller isolation technics, consider the friction force between the paper, by moment and the pressure that separate roller suitably is set, can many supply paper.
According to the diversity of recording medium, more and more require on for example very heavy paper, elevated projecting (OHP) paper and fine arts rubber sheet paper, to form image.In addition, according to the needs of ever-increasing colour print, also more and more require to form image on coated paper, this coated paper has coating surface, so that increase whiteness and glossiness.
But, when the resin material that produces electric charge by meeting in dry environment when paper forms (for example OHP paper and fine arts rubber sheet paper), paper surface is because the friction between them and charged gradually in supplying with operating process.Therefore, because coulomb (Coulomb) power, paper clings mutually.Therefore may produce and pick up fault or double supply.
When being coated paper, under the high humility situation, paper may cling mutually.Therefore, in the common separation technology, may produce and pick up fault or double supply.This is because of the friction force of only considering in the common separation technology between paper.
When being above-mentioned special paper, the friction force between paper is equal to or less than the friction force of normal paper.But, at the bonding force that causes owing to the triboelectric charge in dry environment between the resin paper and more much higher than the friction force between the paper at the bonding force under the high humility situation between the coated paper.Therefore, in the common separation technology, these special papers can not be separated.
In order to eliminate the above-mentioned powerful bonding force between the paper, a kind of sheet feeding-device has been proposed, it has the bonding cancellation element of auxiliary air, and the bonding cancellation element of this auxiliary air blows to the paper buttress with air from sidepiece.This sheet feeding-device blows to the paper buttress with air from sidepiece, thereby has eliminated the bonding force between paper in advance.After the bonding force of having eliminated between the paper, pick-up roller is sent paper.The separating part that is arranged in the pick-up roller downstream makes a piece of paper separate with other paper.This device is used for printer industry and some duplicating machine.
Different with the common unit that only uses the friction isolation technics, have the paper that the feedway of the bonding cancellation element of auxiliary air can separate even cling very doughtily, this is because it had eliminated bonding before supplying with.For this supply technology of using the bonding cancellation element of auxiliary air, for example in the open No.11-005643 (corresponding to U.S. Patent No. 6015144) of Jap.P., propose.
Figure 16 has represented to have the example of the sheet feeding-device 155 of the bonding cancellation element of auxiliary air.This sheet feeding-device 155 comprises: supply dish 156, paper S are loaded in this supply dish 156; And sheet feeder spare (not shown), this sheet feeder spare is sent paper from supply dish 156.Sheet feeding-device 155 also comprises the blowning installation 71 as the bonding cancellation element of auxiliary air.Blowning installation 71 blows to air the sidepiece of paper buttress and blows over the top of paper buttress from the direction vertical with the side surface of paper buttress.
Sheet feeding-device 155 also comprises air motion device 157, and this air motion device 157 comprises electric notor 121 and cam disc 123.Motor 121 makes cam disc 123 rotate, so that make blowning installation 71 vertical movements.Like this, air-flow vertical movement.
The open No.2001-48366 of Jap.P. discloses a kind of device, and it comprises the bonding cancellation element of auxiliary heat air, can be by blowing the dry paper by the air of heater heats.This especially can be at the bonding force that weakens under the high humility situation between the coated paper paper.
But, use the above-mentioned sheet feeding-device of bonding cancellation element of auxiliary air or the bonding cancellation element of auxiliary heat air need use for example such device of blowning installation, heating arrangement and electric notor.Therefore, this sheet feeding-device is used for relatively large supply platform (capacity of this supply platform is 2000 to 4000 paper).Therefore, when being used for the such device of duplicating machine for example, this feedway can only be used at a high speed and high-grade model, and bigger supply platform can be installed in above it.
Therefore, this feedway can not be used for relatively low and medium model (bigger supply platform can not be installed in above it) and office with model (its installing space is limited).When these models were used highly bonding paper, paper can not separate, and may produce double supply.
