Definitions

  • the innovation relates to a storage container for toner concentrate for use in an electrophoretic development device for developing, for example, electrographically, electrophotographically or electroradiographically recorded charge patterns.
  • fresh toner After toner has been consumed during the development process by being attached to the charge image to be developed, fresh toner must be metered in continuously or at certain time intervals in order to keep the concentration of the toner in the developer mixture constant.
  • the toner is usually metered in via a storage container from which the toner is mixed into the developer mixture.
  • the innovation is based on the task of designing a storage container with simple means in such a way that sedimentation of toner in the storage container is avoided in a simple manner and that opening and closing of the storage container can nevertheless take place easily and unimpeded.
  • a closure cap for the opening of the storage container, which in turn has an opening that can be closed by a valve, a shaft is rotatably mounted in the closure cap, one end of which protrudes into the interior of the storage container and the other end of which can be driven from outside the closed storage container is, and in the interior of the reservoir an impeller is provided which is attached to the shaft and the wings of which are pivotable from a plane substantially perpendicular to the shaft in a direction substantially parallel to the shaft.
  • the impeller can be driven in rotation, so that the T onerkonzentrat mixed in the reservoir and sedimentation can be avoided by toner.
  • the wings of the impeller collapse, so that they can be easily pulled out of the storage container through the neck of the preferably bottle-shaped storage container.
  • the storage container is shown in its functional position, in which the opening of the storage container points downward, so that the toner concentrate located in the storage container can flow out of the bottle under the effect of its gravity.
  • the storage container comprises a bottle-shaped storage cartridge 1, which can be closed by a screw-on cap 2.
  • the closure cap 2 has a tubular connection piece 3, the two openings of which can be alternately closed by the sealing cones 4, 5 of a double-cone valve.
  • a pipe section 6 connects the two sealing cones 4 and 5 to one another.
  • a guide cross 7 running radially to the axis of the pipe section 6 is attached to the pipe section 6 and ensures the centering of the double-cone valve.
  • a drive shaft 8 is guided on the one hand within the pipe section 6 and furthermore via a support cone 9 which is integrally formed on the inside of the closure cap.
  • the support cone 9 has openings 9 a in order to let the concentrate inside the storage container pass through.
  • a helical spring (14) tensioned between the supporting cone 9 and the sealing cone 4 ensures that the sealing cone 4 is in the sealing position in the absence of other forces.
  • a cylindrical bearing block 10 is attached at the upper end of the shaft 8.
  • two grooves 11 parallel to each other and to the shaft 8 are formed.
  • the ends of two mixing blades 12 and 13 protrude near the axis, which extend over one, extend into these grooves
  • Bearing pin 14 are pivotally mounted on the bearing block 11.
  • the two mixing blades 12 and 13, are freely pivotable between two end positions. In the operating position they are in the solid line position shown in the figure, the lower edges 12 a, 13 a of M in the respective lower face 11 resting ischeriel a of the grooves. 11
  • the other end position, shown in broken lines in the figure, is defined by the abutment of the two edges 12 b and 13 b (not shown in the figure) with the lower groove surface 11 a.
  • the two mixing blades 12 and 13 In the operating position of the storage container shown in the figure, in which the closure cap is at the bottom, the two mixing blades 12 and 13 automatically fold into their expanded position under their own weight. If the closure cap is now screwed on in any position of the storage container and removed from the cartridge 1, the mixing blades also fold up automatically so that they can be removed from the cartridge without further ado.
