Definitions

  • the invention relates to a storage container for pulverulent material which is transported to a storage container with the aid of a conveying device, in particular for the supply of toner powder from a storage container into the developer station in a non-mechanical printing or copying device.
  • Non-mechanical printing or ropier devices can work, for example, according to the electrophotographic or electrographic process.
  • charge images of the characters to be printed or copied are generated on a recording medium or an intermediate medium, for example a drum, on a semiconductor layer made of photoelectric or dielectric material.
  • These charge images must be developed for visualization. To do this, they are replaced by an Ent winder station, which also contains the toner powder.
  • the toner powder is brought close to the charge images, for example with the aid of magnetic brushes, and merges with them at the points where the charge images are present on the recording medium or intermediate carrier.
  • These powder images are then either fixed directly or, if an intermediate carrier is used, they are transferred to a recording medium, for example a paper web, and only then fixed.
  • toner powder When operating such a printing or copying device, toner powder is thus constantly consumed in the developer station. It must therefore be constantly replenished. It must be taken into account that the toner powder, a powdered plastic, is difficult to pour, is not free-flowing and easily clumps.
  • the object on which the invention is based is to specify a storage container for powdered material which is transported to a consumption container with the aid of a conveying device, in which the powdery material is prevented from clumping and which is also of simple construction.
  • This object is achieved in that the storage container consists of a round part and a further part starting from the round part, and in that a device with a peeling wire is arranged in the round part, through which the powdery material can be removed from the housing wall of the storage container .
  • the further part of the storage container is a uniformly tapering part starting from the round part.
  • the other part thus has inclined walls which prevent the powdery material from adhering to this area.
  • a simple construction of the device with the peeling wire is obtained if it consists of an axis rotatably arranged in the storage container, which has a side part adjacent to each longitudinal wall of the container, and of at least one peeling wire which is arranged between the two side parts.
  • the housing of the storage container consists of a round part RT and a further part starting from the round part.
  • the other part tapers evenly starting from the round part RT.
  • a filling opening OF for the powdery material e.g. Toner powder provided.
  • This filling opening OF can be covered during operation. This is not shown in the figure.
  • the end of the round part RT facing away from the further part WT likewise contains an opening T0 at which a delivery pipe FR is arranged.
  • This conveyor pipe FR can be screwed onto the round part RT, but it can also be part of the housing of the storage container.
  • a conveyor spiral SP can be arranged in the conveyor tube FR.
  • a device is provided in the round part RT of the storage container, which with a peeling wire DR is provided. It consists of a rotatably arranged axis AC, which contains disc-shaped, side panels SE adjacent to the front and rear walls LW of the storage container.
  • the peeling wires DR are arranged between the side parts.
  • the skewed wires DR lie in such a way that, when the axis AC rotates, they run in the vicinity of the housing wall of the storage container.
  • the AC axis is driven by a motor MO, which can simultaneously drive the conveyor spiral.
  • the storage container is usually made of powdery material, e.g. Toner powder, filled.
  • the storage container can be filled with powdery material up to the marking MK.
  • the further transport of the powdery material to a consumption container is carried out by the conveyor device with the conveyor spiral SP. Since the powdery material has very poor pouring properties and very readily adheres to the housing wall, the powdery material does not slip down to the conveyor pipe FR despite being transported further through the conveyor device. To prevent this, the device is rotated with a peeling wire DR. With the peeling wire DR, the powdery material is easily removed from the housing wall and the powdery material is loosened. As a result, it slides on to the conveyor pipe FR.
  • powdery material e.g. Toner powder
