Definitions

  • the invention relates to a conveyor with metering pumps for the removal of materials from containers, in particular for 2-component systems, which are powered by an air motor is drivable with one arranged in a pump cylinder and movable back and forth by means of a piston rod Piston and suction and connected to the pump cylinder Output lines, with one at each pump cylinder end Intake and outlet line is connected, one in each inlet and outlet line in the same flow direction Acting check valve is switched on, the intake lines and output lines in the flow direction connected before or after the check valves are and the air motor with its drive piston in axial Extension of the piston rod of the metering pump arranged is.
  • the invention has for its object a conveyor with dosing pumps, especially for the promotion of two or more components, so that they form one simple to set up and therefore inexpensive to manufacture is subject to little wear and tear others easy to assemble and disassemble.
  • a metering pump designed according to the invention is thus the piston rod of the pump cylinder directly with the piston rod connected to the air motor so that forces from the air motor introduced into the dosing pump without any tilting moment will.
  • the housing of the air motor is rigid with that Housing of the metering pump connected so that the piston rods of air motor and metering pump are coaxial.
  • the packs are subject to less wear.
  • connection holes are formed directly in the plates, whereby advantageously also the check valves directly attached to the plates.
  • the plates themselves are through Tie rods connected together so that the exchange of the Pump cylinders, pistons as well as packings by disassembly only fewer parts can be reached.
  • the check valves are advantageously arranged so that these are parallel to each other, with corresponding Arrangement of the metering pump unit is achieved close the check valves solely due to gravity. This has the advantage that additional springs etc. can be dispensed with.
  • An embodiment of the invention is based on the drawing described below, which is a metering pump unit, partly in section, shows.
  • the dosing pump unit shown in the drawing is used for conveying two material components in containers 1, 2 are delivered. One is placed in each of these containers Line 32, each in two suction lines 3, 4th divides. These suction lines 3, 4 are with the metering pump unit 5 connected.
  • Each metering pump unit is formed from two plates 6, 7, which are connected by tie rods 8. Between the plates 6, 7, a pump cylinder 9 is clamped and sealed against the plates 6, 7 by means of seals 10. A piston 11 is arranged in the pump cylinder, on both sides each has a piston rod 12, 13.
  • the piston rod 12 or 13 of the metering pump 5 is directly connected to the piston rod 23 of an air motor 24.
  • This air motor is formed by two plates 25, 26 between which a cylinder 27 is clamped.
  • the Plates 25, 26 are connected to one another by tension rods 28.
  • the plates 21 and 26 of the air motor are via spacer elements 31 rigid with the plates 6, 7 of the metering pump 5 connected.
  • the air motor reverses itself, i. H. when the respective end position of the piston 29 is reached a two-way valve 30 switched accordingly.
  • the dosing pump works as follows.
  • the piston 11 is off the position shown moved to the left, so via the suction line 3 and the check valve 16 material conveyed from the container 1, 2. That in the pump cylinder 9 located material is to the left via the bore 14, the Check valve 16 pushed into the outlet line 20, 22, the check valve 15 a return flow of the material prevented in the container 1.
  • the piston 11 has the left one End position reached, this is achieved by the air motor 24 moved in the opposite direction, then via the suction lines 4 and the check valve 15 material from the Container 1, 2 is sucked.
