Definitions

  • the present invention relates to a varnish feeding apparatus for a varnish pouring machine, which includes a pouring vessel with a nozzle, and a conveyor passing a work piece below the nozzle of said pouring vessel.
  • the primary feature of the arrangement according to the present invention consists in that the supply from the pump to the pouring vessel is passed through a control valve and a filter, while the rate of supply is adapted to be varied with the aid of a by-pass line by-passing said filter and leading from the pressure side of the pump to its suction side. In this way, the pump delivery can remain constant.
  • the arrangement according to the invention also includes deviating plates or the like to prevent the formation of foam in the varnish while it is being poured upon the work piece.
  • the arrangement shown therein comprises a varnish tank 1, from which the varnish passes through a pipe 2 to a pump 3, e.g. a gear pump, and hence through the pipe lines 4 and 5 to a filter-box 6 with a filter screen 7, through the latter and through pipe lines 8 and 9 into the pouring vessel 10.
  • the varnish 12 flows through a nozzle 11 at the bottom portion of vessel 10 upon a work piece 13 which is passed below the nozzle 11 by means of a conveyor belt 14.
  • the excess varnish 12a flows from the work piece 13 into a collector trough 15 and through an outlet pipe 15a thereof back into the varnish tank 1.
  • Branching off from pipe 4 is a by-pass cricuit comprising pipe lines 16 and 17 with a valve 18.
  • the said by-pass circuit by-passes the filter-box 6 and leads into the supply line 2 which latter leads to the suction side of pump 3.
  • a valve 19 Arranged in pipe 5 is a valve 19 by means of which the supply from the pressure side of pump 3 through line 5 to the filter box 6 can be varied. Said valve 19 may also for certain purposes referred to below be closed whenever necessary.
  • Communicating with pipe 16 is a discharge pipe 20 comprising a valve 21 and being connected to a hose 22.
  • the bypass pipe lines 16, 17 convey a portion of the varnish supplied by pump 3 back into the suction line 2.
  • the valves 18 and 19 the rate of supply of varnish to the pouring vessel 10 can be accurately adjusted, while the pump delivery remains constant.
  • the pouring vessel 10 is provided with a venting valve 23.
  • valve 23 For purposes of cleaning the pipes and containers, the valve 23 is opened first and the pump 3 is stopped so that the varnish of the pouring vessel will flow into the collector trough 15 and from there into the varnish tank 1.
  • the valve 21 which is normally closed is then opened while the valves 18 and 19 are closed and pump 3 remains in operation. In this way, the tank 1 is emptied through pipes 16 and 20 and hose 22 into a container not shown.
  • valve 18 is opened so that the by-pass circuits 16, 17 will likewise drain. Opening of the small venting valve 24 will also allow draining of the pipe 9,
  • a solvent is poured into the varnish tank 1, and the motor M is started again, whereupon the solvent is discharged through hose 22 in the manner described above while simultaneously a cleaning of the circuit and parts therein will be effected.
  • a second cleaning cycle for the vessels and pipe lines is then performed with a fresh solvent likewise in the manner described.
  • the solvent used in the first cleaning cycle contains much varnish and can again be used for diluting the varnish.
  • the second solvent is preserved and may be employed for performing the above mentioned first cleaning cycle when another cleaning operation of the arrangement is required.
  • the pouring vessel 10 has arranged therein deviating plate means such as a plate 25 which deflects the varnish flow entering through pipe 9 toward the walls of the vessel 10 in order to cause the varnish to flow along the walls of container 16.
  • deviating plate means such as a plate 25 which deflects the varnish flow entering through pipe 9 toward the walls of the vessel 10 in order to cause the varnish to flow along the walls of container 16.
  • the collector trough 15 may have similar plates 26 arranged therein which will prevent the varnish draining from the work piece from freely dropping into the trough.
  • tank 1 is advantageously provided with deviating plate means 27, 28 for deflecting the varnish supplied thereto toward the tank wall.
  • a reservoir adapted to receive and store varnish, said reservoir being provided with a discharge opening; a gear pump having a pressure side and a. suction side, first conduit means leading from the discharge opening of said reservoir to the suction side of said pump, a varnish feed-' ing vessel closed at the top and having a discharge slot at its bottom for discharging varnish upon a work piece passing therebelow, second conduit means leading from the pressure side of said pump to said feeding vessel for conveying varnish thereto from the pressure side of said pump, third conduit means interconnecting said discharge opening and the pressure side of said pump for causing varnish delivered by said pump to by-pass said second conduit means, and valve means arranged in at least one of said second and third conduit means and operable to control and vary the rate of supply of varnish through said second conduit means to said varnish feeding vessel.
