Definitions

  • the invention relates to a device for the metered dispensing of single or multi-component adhesive, sealing, filling or leveling compounds, with an axially displaceable squeezing piston which has a piston rod provided with tooth pegs of a certain pitch, one by means of a feed device by a certain stroke operable transport catch engaging in the toothed catches of the piston rod and a holding catch also engaging in the toothed catches of the piston rod.
  • the invention has for its object to provide a device that enables contamination-preventing delivery of mass.
  • this is achieved in that the distance between the transport peg and the holding peg measured parallel to the feed direction is smaller than an integer multiple of the division when the transport peg is actuated.
  • the arrangement according to the invention prevents the retaining catch from engaging at the end of the transport stroke.
  • the ejection piston can thus be pulled back a certain distance until the holding catch engages, and the overpressure in the cartridge in the process be dismantled. This pressure reduction therefore takes place automatically after each piston stroke.
  • the stroke of the transport peg is adjustable.
  • the stroke is adjusted by one division of the tooth catches on the piston rod.
  • the stroke of the transport catch can be changed, for example, by adjusting a stop.
  • the path allowing the masses to relax is specified by determining the distance between the transport peg and the holding peg measured parallel to the feed direction when the transport peg is actuated.
  • the stroke and the distance between the transport peg and the holding peg when the transport peg is not actuated are thus always adjusted by the same amount. As a result, the distance between the transport peg and the holding peg remains constant when the transport peg is actuated.
  • the transport peg and the holding peg can in principle be designed as desired.
  • the transport catch and / or the holding catch can be designed as radially displaceable pawls which can be acted upon by a spring element. Due to the radial displaceability of the detents, the distance between the detents measured during insertion and Disengage not changed.
  • compression springs can be used as spring elements.
  • a radially resilient ring spring is particularly space-saving.
  • the pressure medium can be supplied, for example, from a compressed air network.
  • a compressed air network When using the device, for example in construction site operation, the independence of the device from supply networks is required.
  • the pressure medium is expediently contained in a cartridge arranged in the device.
  • compressed compressed air, CO 2 or another gas can be used as the pressure medium.
  • the cartridge can be integrated in the device or can be designed as a separate, replaceable part.
  • a cylinder 7 is arranged on the shaft 3a of the guide part 3.
  • a piston 8 is guided axially displaceably in the cylinder 7 and on the shaft 3a.
  • the piston 8 is sealed off from the shaft 3a and the cylinder 7 by two sealing rings 9, 10.
  • Two opposing transport pegs 11 are arranged in the piston 8.
  • the transport catches 11 protrude through slots 3b of the guide part 3 and are brought into engagement with the tooth catches 4b of the piston rod 4a by means of an annular spring 12.
  • a compression spring 13 brings the piston 8 into the starting position shown.
  • the cylinder 7 is axially displaceable on the shaft 3a. By moving the cylinder 7, the stroke of the piston 8 is changed.
  • a set screw 14, which can be loosened and tightened through an opening 1d in the housing 1, is used to lock the cylinder 7 in a specific position.
  • a cartridge 15 is arranged in the handle lc.
  • the cartridge 15 contains a pressure medium, for example compressed air or CC 2 .
  • the cartridge 15 is held in the handle 1 c by a closure cap, denoted overall by 16, and a union screw 17.
  • the closure cap 16 has a mandrel 16a and a head 16b protruding beyond the coupling screw.
  • the closure cap 16 can be displaced in the handle lc to a limited extent and is sealed by a sealing ring 18. After inserting a new cartridge 15, this is opened by a blow on the projecting head 16b of the closure cap 16 through the mandrel 16a.
  • the closing cap 16 is then brought back into the position shown by the pressure medium flowing out.
  • the pressure medium enters the space surrounding the cartridge 15 and from there through a bore le to a pressure relief valve.
  • the pressure relief valve consists of a slide, generally designated 19, a compression spring 20 and a locking screw 21.
  • the slide 19 is pressed to the left by the compression spring 20, so that a transverse bore 19a in the slide 19 comes to coincide with the bore le.
  • the pressure medium can thus flow through the bore le and the transverse bore 19a.
  • the slide 19 is acted upon by the pressure building up on the left side of the slide 19 and is thereby pressed against the compression spring 20.
  • the slide 19 is moved to the right into the position shown and the hole le is closed. If the pressure drops, the slide is pushed back to the left by the compression spring 20 and the bore le is opened.
  • the pressure after the pressure relief valve can thus be kept largely constant. From the pressure relief valve, the pressure medium reduced to a certain pressure passes through a channel lf to a discharge valve.
  • the dispensing valve consists of a plunger, designated overall by 22, and a spring 23.
  • the plunger 22 is provided with an annular groove 22a.
  • a pusher 24 arranged on the handle lc is actuated, the plunger 22 is displaced to the right against the force of the spring 23.
  • the annular groove 22a thereby reaches the region of the channel 1f.
  • the pressure medium can thus continue to flow and passes through a pipe 25 into the cylinder 7, where the piston 8 acts and is shifted to the left against the force of the spring 13.
  • the ejection piston 4 together with the base 2b is likewise displaced to the left by the transport catches 11 which engage with the piston rod 4a, and a certain amount of mass is displaced from the cartridge 2 through the mouthpiece 2a.
  • the plunger 22 returns to the position shown.
  • the pressure medium still contained in the cylinder 7 passes through a bore 22b and a vent lg in the housing 1 to the outside.
  • the piston 8 can thus be returned to the starting position by the compression spring 13.
  • Due to the transport catches 11 which are in engagement with the tooth catches 4b of the piston rod 4a the squeeze-out piston 4 is likewise carried along until the retaining catch 5 engages in the next tooth catch 4b.
  • the partial retraction of the ejection piston 4 reduces the pressure in the cartridge 2 and prevents further mass flow out of the mouthpiece 2a.
  • the squeezing piston 4 is rotated through 90 °.
  • the holding button 5 and the transport pegs 11 get into the groove 4c of the piston rod e a.
  • the squeeze-out piston 4 can then be pushed back into the rearmost starting position without hindrance.
  • the device is ready again.
  • the union screw 17 must be unscrewed.
  • the sealing ring 18 is disengaged from the sealing seat before the cap screw 17 is completely unscrewed. This means that the pressure that is still present can be safely reduced. After inserting a new cartridge 15, this is in turn opened by striking the head 16b of the closure cap 16.
  • FIG. 2 shows, arranged at a distance from one another, the holding button 5 and one Transport peg 11.
  • the distance measured parallel to the feed direction is denoted by b.
  • the piston 8 When the piston 8 is actuated, it is moved together with the transport catch 11 by the stroke h relative to the guide part 3. After an empty travel 1, the piston rod 4a is also taken along.
  • the stroke h changes. However, only the free travel 1 changes for the time being.
  • a change in the advance of the piston rod 4a is only achieved when the free travel 1 becomes greater than a pitch t of the toothed catches 4b of the piston rod 4a. In practice, this means that the transport catch 11 comes into engagement with the next tooth catch 4b of the piston rod 4a.
  • FIG. 3 shows the position of the holding catch 5 and the transport catch 11 when the transport catch 11 is actuated.
  • the distance a between the holding catch 5 and the transport catch 11 is less than an integer multiple of the division t of the tooth catches 4b.
  • the holding button 5 is therefore not yet fully engaged.
  • the piston rod 4b is taken along the path s until the holding peg 5 is engaged.
  • the partial retraction of the piston rod 4a causes the described pressure reduction in the cartridge 2.
  • the path s remains constant regardless of the adjustment of the stroke. The relaxation remains the same.
