Definitions

  • ABSTRACT Chamber-defining means define a closed chamber, a sealing inlet to and a sealing outlet from said chamber.
  • Stock-feeding means are provided for continuously moving stock to be oiled through said inlet, chamber, and outlet along a predetermined path.
  • a row of nozzles open in said chamber and are spaced apart transversely to said path and directed toward said path and operable to discharge an oil-air mixture toward said path.
  • Each of said nozzles comprises a needle, which is displaceable to vary the rate at which said oil-air mixture is discharged from said nozzle.
  • An oil conduit and a compressed-air conduit are connected to said nozzles.
  • An automatic control system is provided to control the rate at which said oil-air mixture is discharged from said nozzles in proportion to the speed of travel of said stock in said chamber.
  • Said control system comprises a sensing roller engageable with said stock and adapted to be driven thereby at a speed which is proportional to said speed of travel, a tachogenerator arranged to be driven by said sensing roller and to produce an output signal representative of said speed of travel, an actuator, a controller arranged to receive said output signal and to control the operation of said actuator in response to said output signal, and a linkage operatively connecting said actuator to said needles and arranged to displace said needles in response to a change of said speed of travel resulting in an operation of said actuator.
  • This invention relates to apparatus for oiling continuously moved stock, particularly sheet metal in the form of strip, plate or sheet, which apparatus comprises a closed chamber, which has a sealing inlet and a sealing outlet for the stock, a plurality of nozzles disposed in said chamber and spaced apart transversely to the direction of travel of the stock and connected to an oil conduit and to a compressed-air conduit, said nozzles being arranged in rows above and/or below the stock and serving to blow an oil-air mixture onto the stock, and each nozzle comprising an adjustable nozzle needle for controlling the rate of flow of oil and compressed air through the nozzle.
  • Another apparatus which comprises nozzles that are disposed in a closed chamber and blow an oil-air mixture onto the strip metal moving through the chamber and through inlet and outlet openings thereof.
  • the apparatus has the disadvantage that the resulting oil mist, which emerges from each nozzle in the form of a spray cone hardly permits of a change of the thickness of the oil film in dependence on the speed of travel although it enables the application of a highly uniform oil film to the strip metal.
  • nozzles such as are employed in commercially available spray guns because they are troublefree in operation and do not require special maintenace.
  • the rate of flow of oil and compressed air through each nozzle is controlled by an adjustable nozzle needle, which inherently does not involve any difficulty.
  • an adjustable nozzle needle which inherently does not involve any difficulty.
  • the adjustment of the individual nozzle needles takes excessively long time. Besides, the adjustment must be carried out by hand so that a nonuniform oil film will be applied to the stock.
  • the above-mentioned object is substantially accomplished according to the invention in that the nozzle needles of the nozzles of one row are adjustable in unison by a lever system or the like, which is operatively connected to an actuator, and a freely rotatable roller engageable with the stock drives a tachogenerator, which is connected to a controller, which controls the operation of the actuator in response to changes of the speed of travel.
  • the rate of oil sprayed by the nozzles can be controlled with relatively simple means so as to ensure the formation of a uniform oil film having a constant thickness on the stock.
  • the controller Upon an increase of the speed of travel, the controller energizes the actuator for an adjustment of the lever system so as to open the nozzles. Oil and compressed air at a higher rate are then blownonto the stock moving at a higher speed so that the thickness in which the oil film is applied is maintained constant.
  • the lever system Upon a decrease of the speed of travel, the lever system is operated by the actuator to move the nozzle needles in the opposite direction so that oil at a lower rate is blown onto the stock.
  • the lever system or the like comprises an actuating lever, which is freely rotatably mounted on a shaft, which is operable to adjust the nozzle needles of a row of nozzles in unison, and another lever, which is secured to the shaft for rotation therewith, is connected to the actuating lever by detent means permitting of an angular adjustment of the two levers relative to each other.
  • the lever system is connected to a shaft, by which the nozzle needles of a row of nozzles are adjusted in unison.
  • the actuator is not connected directly to the shaft but to an actuating lever, which can be fixed in any of several positions relative to the lever which is secured to the shaft.
  • the detent means provided for this purpose enable a basic setting of the nozzles.
  • the detent means comprise a toothed element, which is firmly connected to or formed by the actuating lever, and a springloaded pin or the like, which is engageable with any of the gaps between the teeth of said toothed element and mounted in the lever which is secured to the shaft.
  • FIG. 1 is a diagrammatical sectional view taken on a line extending in the longitudinal direction of the stock and shows apparatus according to the invention for oiling continuously moving stock.
  • FIG. 2 is a side elevation showing the apparatus and FIG. 3 is a sectional view taken on line IIIIII of FIG. 1.
  • a metal strip 4 is moved through a closed chamber 1 and through an inlet 2 to said chamber and an outlet 3 from said chamber.
  • Two pairs of rollers 5 and 6 are disposed in the chamber and operable to move the strip. These pairs of rollers can be adjusted in height for an adjustment of the roller nip to the thickness of the strip.
  • Two rows of nozzles 7 and 8 are disposed above and below the strip 4, respectively. The nozzles of each row are connected to a common oil conduit 9 and a common compressed air conduit 10.
  • the rate of flow is adjustable by means of nozzle needles 11, which are adjustable by means of forked levers 14, which are clamped to respective shafts 12 and 13.
  • the shafts 13 and 12 are rotatably mounted in the chamber 1.
  • a lever 15 is secured to the shaft 12 for rotation therewith.
  • a spring-loaded detent pin 16 is mounted on the lever 15.
  • An actuating lever 17 is rotatably mounted on the shaft 12 and provided with a toothed segment 18, which is engaged by the detent pin 16 to inter
  • a tachogenerator is driven by a freely rotatable roller 19 engaging the strip 4 and is connected to a controller 21, which switches an actuator 22 in response to changes of the seed of the strip.
  • the displaceable screw 23 of the actuator 22 is articulatedly connected to the actuating lever 17.
  • the tachogenerator 20 and the controller 21 switch the actuator 22 so that the actuating lever 17 is pivotally moved by the detent means 16, 18 to the lever 15 and the latter is secured to the shaft 12 for rotation therewith, the shaft 12 is rotated at the same time and the nozzle needles 11 are uniformly adjusted by the forked levers 14.
  • the shaft 13 carries a lever 24, which is operatively connected to the lever 15 by a link 25.
  • the basic setting of the nozzles 7 and 8 will provide for the desired thickness of the oil film formed on the stock.
  • the detent means are disengaged and the levers 15 and 17 rotated relative to each other.
  • the detent pin mounted on the lever 15 snaps into the appropriate tooth gap of the toothed segment 18 so that the lever 15 is fixed in position relative to the lever 17.
  • This setting results also in the setting of the nozzles below the strip because the two shafts 12 and 13 are operatively connected by the link 25.
  • a change of the speed of the strip 4 during the operation of the apparatus results in an energization of the actuator 22 so that its screw 23 imparts to the actuating lever 17 a pivotal movement in a direction to increase the rate at which oil is sprayed by the nozzles onto the strip. Oil at a higher rate is now blown onto the strip moved at a higher speed so that the thickness of the oil film is maintained constant.
