Definitions

  • the invention relates to a device for oiling strip-shaped or tabular sheets with a plurality of nozzles distributed transversely to the conveying direction of the sheets, which are connected to the pressure line of piston pumps which can be driven as a function of the conveying speed of the sheets, the suction lines of which are fed via a feed pump to an oil reservoir stay in contact.
  • the feed pump must be switched off during operation of the vacuum pump, which entails the risk that air will accumulate in the suction spaces of the feed pump.
  • This fact does not play a special role in the known oiling device, because the uniform oil distribution on the oiled sheets is to be ensured via the application rollers, so that irregularities in the oil supply are compensated to a certain extent. Due to the use of application rollers, the achievable uniformity of the applied oil film remains limited.
  • the changeover of the oiling machine to a different type of oil is complex because of the necessary suction of the previously used oil.
  • the invention is therefore based on the object of providing a device for oiling sheet-like or sheet-like sheets, which not only ensures a particularly thin and uniform oil film on the sheet surface, but also allows rapid changeover from one type of oil to another.
  • the invention achieves the object in that at least one further oil storage container is provided, to which a separate feed pump is assigned, that the feed pumps assigned to the storage containers are selectively connected to the suction lines of the piston pumps or to a return line by means of a switch can be connected to the associated storage container and that each storage container has a heater.
  • the heater associated with each reservoir also allows the oil temperature to be selected as a function of the type of oil, so that spray conditions which are the same for different types of oil are also achieved with regard to the oil viscosity.
  • the illustrated device for oiling sheet-like or tabular sheets has a housing 1 which forms a spray chamber 2 through which the sheet to be oiled passes.
  • nozzles 4 which are combined to form spray bars 3 and are arranged transversely to the direction of passage of the sheets, are provided and are connected to the pressure lines 5 of piston pumps 6.
  • the arrangement is such that the piston pumps 6, which are combined in sets in a common pump housing, are each connected to their own nozzle 4, so that it is ensured that each nozzle actually sprays the same amount of oil with each working stroke of the piston pumps.
  • the drive motor 7 for the piston pumps 6 must be controlled as a function of the throughput speed of the metal strips.
  • the oil supply to the piston pumps 6 takes place via a changeover switch 8, which optionally connects the suction lines 9 of the piston pumps 6 to one of two oil reservoirs 10 and 11. These oil reservoirs 10 and 11 are each provided with a separate feed pump 12 which is connected to the changeover switch 8 via a downstream filter 13. Depending on the position of the changeover switch 8, the piston pumps 6 are therefore supplied with oil via the corresponding feed pump 12 either from the storage container 10 or from the storage container 11.
  • the switch 8 causes the feed pump 12, which is not connected to the piston pumps 6, i.e. the feed pump of the storage container 11 in the switch position shown, to pump the oil from the associated container in the circuit via a return line 14, which leads to air accumulations in the suction chamber of the pump 12 or prevented in the downstream filter 13.
  • the switch 8 is switched over, the piston pumps 6 can consequently be supplied with the oil from the other container undisturbed.
  • the storage containers 10 and 11 are each provided with a heater 15, which ensure a corresponding oil temperature.
  • the oil is fed into the storage containers 10 and 11 via feed lines 16 which open into a prechamber 17 of the storage containers 10 and 11.
  • the oil pumped into the pre-chamber 17 passes through a curved overflow 18, which, like the pre-chamber 17, serves to separate oil contamination, into the actual reservoir chamber 19, in which the oil level is regulated by two floats 20, which feed fresh oil into the pre-chamber 17 taxes.
  • the excess oil collecting in a floor pan 21 of the spray chamber 2 is returned via a line 22 with the aid of the switch 8 to the storage container 10 or 11 in use, the branch lines 22a and 22b of the line 22 in the prechamber 17 of the respective storage container 10 or 11 open to ensure dirt separation.
  • the piston pump sets combined in common housings are drive-connected to one another via couplings 24, so that the drive of these piston pumps can be switched off, which, of course, with a constant delivery capacity of the feed pumps 12 results in a larger amount of excess oil which is returned via the excess line 23.
