Definitions

  • the invention relates to a device for monitoring the supply of writing fluid in a storage container for an ink writing device which changes its storage volume in accordance with the consumption of writing fluid, in which the storage container is arranged on a writing carriage which can be moved along a guide.
  • a writing head which is moved along a recording medium, is generally supplied with writing liquid from an ink supply container by means of a motor device. If this ink supply container is arranged integrated in a writing head, visual monitoring of the ink supply in the container is not possible. Constant monitoring of the ink supply is particularly necessary when using writing devices in telex and data traffic.
  • DE-A-26 17 730 describes a device for monitoring the ink supply in ink writing devices.
  • electrodes are available that make it possible to interrogate the liquid level electrically.
  • DE-B-2610 518 describes an ink reservoir for ink writing devices which is held interchangeably and which has a device in the form of a stamp which makes it possible to briefly increase the pressure in the ink reservoir.
  • Such a brief increase in ink pressure is in ink writing devices, e.g. Piezoelectrically operated writing nozzles contain necessary to remove any trapped air from the supply system due to the physical principle used when commissioning such an ink writing device or when the ink reservoir is replaced.
  • the object of the invention is to provide a device of the type mentioned at the outset for ink writing devices and the like, which is simple and reliable, and which includes a simple and inexpensive design of the ink reservoir.
  • the storage container has a plunger which is supported on the storage volume and protrudes from the housing cover of the storage container as a function of the changing storage volume, and in that a stationary, the plunger sensing device is provided.
  • the sensing device consists of a fork-shaped switching rocker which can be pivoted against a spring force, with a slide piece formed thereon and a run-up slope for the housing cover, and a push-button lever for the plunger, which actuates an electrical switch and is arranged perpendicularly to this slide piece against spring force.
  • the device for increasing the pressure which is necessary per se in the writing devices of the type mentioned at the same time for scanning the ink supply.
  • the plunger of the ink bottle which is arranged on the movable writing mechanism, moves against a frame-fixed switch for scanning. This makes it possible to monitor both the presence of an ink bottle and the ink supply with just one decision criterion.
  • the main advantages are that no additional electrical connections have to be made to the carriage and that it is no longer necessary to conduct contacts inside the ink bottle.
  • the entire device is extremely inexpensive and reliable. If, in addition, according to a development of the invention, the plunger is provided with markings, the change in the ink supply can be observed directly.
  • an ink supply bottle 3 is arranged on a writing carriage 2 provided with a writing head 1.
  • the writing carriage 2 is thereby moved line by line along guides 4 via an electromotive drive device, not shown here.
  • the ink supply bottle 3 itself consists of a cylindrical housing made of plastic material with an inserted plastic ink bag on which a plunger 5 rests.
  • This plunger 5 essentially has two functions: on the one hand, it serves as a pressure plunger, for example to briefly increase the pressure in the ink system when the ink bottle is replaced, in order to prevent air from entering the ink supply system to remove, on the other hand also as a display means for the ink supply in the ink supply bottle 3.
  • the plunger lowers from an initial state (FIG. 1), in which the distance a) from the cover 6 the ink supply bottle 3 protrudes until it reaches a level (FIG. 3) at which the supply volume of the ink supply bottle 3 has decreased to a minimum volume.
  • the plunger 5 In order to be able to determine the remaining supply visually without electronic aids, it is possible to provide the plunger 5 with colored markings so that the supply state of the ink supply bottle 3 can be determined immediately when the ink supply bottle is unscrewed.
  • the plunger is scanned via an infrared light barrier or the like.
