Definitions

  • This invention relates to a method for automatically feeding sheets of filter paper. for example. as in an apparatus for the analysis of substances suspended in water and to a device therefor.
  • a primary object of this invention is to provide a method for feeding individual sheets of paper of any kind and size safely one by one and a device for practic ing said method.
  • Another object of this invention is to provide a paper feeding device so small in size and simple in structure as to be readily incorporated, for example into a known automatic measuring system.
  • the paper feeding device comprises a magazine for storing a stack of paper, a sucker serving to draw up individual sheets of paper one by one from the stack of paper stored in said magazine, a means for blowing air against the paper clinging to said sucker. and a means for driving said sucker so as to transfer the drawn up paper to a required position.
  • the sucker happens to draw up two or more sheets of paper at a time.
  • air of a prescribed pressure is blown against the paper now clinging to the sucker to blow down any extra sheets entrained by the uppermost sheet being transferred. enabling the individual sheets of paper to be transferred one by one to the required position.
  • FIG. 1 is a side view illustrating in outline one preferred embodiment of the paper feeding device according to this invention.
  • FIG. 2 is a top plan view of the embodiment shown in FIG. 1.
  • FIGS. 3 and 4 are cross-sectional views each illustrating a preferred embodiment of the mechanism of this invention for preventing the uppermost sheet of paper from entraining any extra sheets of paper while it is being transferred to said desired position.
  • a dry chamber 1 encases a magazine 2 which holds therein a stack of circular filter paper 6 to be fed.
  • a suitable heating means 3 such as an electric bulb is disposed so as to keep the interior of said chamber at a constant temperature and prevent the stack of filter paper from getting moist.
  • a sustainer 4 which is provided at the forward end thereof with a sucker 5 adapted to suck up the paper.
  • Said sustainer 4 is secured to one end of an arm 7 the other end of which is fastened to a shaft 8.
  • the shaft 8 is driven in a vertical direction by a vertical drive unit 9 and rotated by a rotary unit 10.
  • the sucker 5 is connected to a pump P. so as to draw up the paper.
  • the magazine 2 is provided along the upper edge thereof with a ring-shaped tubular member [2 containing a plurality of orifices I3 for discharging air.
  • This tubular member 12 serves to blow the air supplied from a pump P toward the center of said ring of tubular member [2.
  • the paper feeding device has a construction as described above.
  • the vertical drive unit 9 is set to motion to cause the sucker 5 to descend onto the top of the stack of filter paper 6 held within the magazine 2.
  • the sucker 5 then sucks up the filter paper by virtue of vacuum produced by the pump P
  • the ring of tubular member I2 has an inside diameter large enough to permit passage of the filter paper and is provided on the inside the reof with a plurality of suitably spaced orifices (three orifices in the illustrated embodiment) which serve to discharge the air supplied from the pump P toward the center of the ring of tubular member.
  • the air pressure overcomes the attraction with which the sucker holds the second and following sheets across the uppermost sheet. with the result that such extra sheets are blown down onto the stack. The extra sheets blown down fall back into magazine 2 where they wait to be picked up in turn.
  • the shape of said tubular member I2 may suitably be modified so as to conform to the shape of paper being handled.
  • the ratio of the magnitude of suction by the pump P, to the magnitude of discharge by the pump P: is a critical factor. This ratio must be determined by taking into due consideration the shape and quality of the particular paper to be handled.
  • the filter paper weighs 0.2g per sheet and measures mm in diameter and the sucker has a sucking area of 13.3 mm"
  • the desired effect is obtained by fixing the magnitude of suction through the sucker at Sl/min. and that of discharge through the orifices at ZOl/min, i.e.. at a ratio of l 4.
  • the stack of paper held within the magazine 2 is mounted on a slightly inclined base 16 and the suction face of the sucker is also inclined by the same degree as said inclined base as illustrated in FIG. 4 so that the filter paper is sucked up by the sucker while still in the inclined position.
  • the air discharged through the orifices is blown against the paper in an inclined direction with reference to the direction of the paper, facilitating the sepa ration of extra sheets from the uppermost sheet which is in direct contact with the sucker.
  • the mechanism of the construction described above thus causes the forced current of air to blow down extra sheets adhering to the uppermost sheet, so that only one sheet of paper is allowed to adhere to the sucker.
  • the arm '7 having just one sheet of filter paper held fast by the sucker is revolved and brought to a position di rectly above a weighing plate 14 and then lowered until the filter paper comes into contact with the weighing plate 14 by means of the vertical drive unit 9.
  • the suction pump P is stopped to allow the filter paper to alight on the weighing plate.
  • the suction and the release of filter paper by the sucker may be effected by inserting a solenoid valve 15 in a pipe connecting the suction pump F and the sucker. which solenoid valve is opened and closed as required by means of a timer (not illustrated).
  • This invention as described above, enables the individual sheets ofa stack of paper to be transferred safely one by one by use of a very simple mechanism.
  • the device of this invention therefore, can be incorporated into any system involving the operation of paper feeding, enabling the operation of the system to be fully automated.
  • a method for feeding paper stacked within a magazine comprising:
  • a device for feeding paper comprising in combina tion:
  • a sucker disposed upon elongated support means and above said stack of paper. adapted to draw the uppermost sheet of paper of said paper stack vertically upwardly from said stack in said magazine as a result of vacuum produced within said sucker by means of a suction pump;
  • a device wherein the stack of paper is stored in an inclined position and the sucking face of the sucker is inclined by the same angle as that of the stack of paper.
