Definitions

  • the invention relates to an element for supplying spray material to a spray gun, in which the parts surrounding and guiding the spray means comprise a tank, a spray nozzle including a nozzle needle and a connecting channel in a web between the tank and the spray nozzle.
  • the inventors have set themselves the task of creating an element of the type described in the introduction, which is suitable for filling and packaging with conventional devices. This object is achieved in that a tight seat is provided at the entrance of the connecting channel, to which the tank can be connected as an exchangeable unit after opening its lid.
  • the tank can be designed as a simple conventional cylindrical can, for example with a diameter of 84 mm and a height of 130 mm, as is customary for paint cans.
  • the spray nozzle and the connecting channel with the seat for the tank at the entrance of the connecting channel are designed as a foot-shaped body which can be inserted into a slip shoe-shaped seat of the gun body.
  • a foot which is separate from the tank, can be used regularly over a longer working period if it is carried out without substantial interruption, so that this foot is used in conjunction with a whole series of paint cans which are also to be disposed of after use and thus the entire cost of the replacement be reduced from element and foot.
  • the foot is preferably provided with a funnel-shaped or cup-shaped upper part, with which it is put over the opened paint can from top to bottom after the correct dose of hardening agent has been introduced into the opened paint can and mixed thoroughly.
  • the dose of hardener required for each paint can can be supplied in a small chamber, for example in the form of a can cap, which is attached to the bottom or the lid.
  • the foot may be made of plastic, while the paint can is conventional, e.g. made of metallic material.
  • the needle of the spray nozzle can be secured in the closed position, for example by a bolt, in such a way that the nozzle is only opened after the foot has been inserted and in the rhythm of the spraying work.
  • the spray gun shown in the drawing and the element are used to apply hardening, flowable substances (spray media), in particular a mixture of plastic and a plastic hardener on surfaces by means of a spray nozzle 6, which has a tank 3 for the spray medium and a feed line 4 on the handle 5 of the gun body can be connected to a compressed air source.
  • the spray head 2 - cf. in particular Fig. 6 - contains a nozzle 6, the outlet opening voltage 7 locked at rest by the tip of a nozzle needle 8 and opened by withdrawing the needle.
  • 1 channels are provided in the gun body, which open into a distribution chamber 10 of the spray head 2 which encloses the front end of the nozzle 6.
  • This distribution chamber is formed by the front of the gun body and a screw flap 11 with a central bore, which forms an annular opening with the nozzle end to produce a concentric atomizer for the spray.
  • the omnidirectional jet produced in this way can be shaped by auxiliary jets inclined towards one another from two sides to form a flat jet with more or less great extent in a plane perpendicular to the plane of the drawing with an adjustable inclination to the plane of symmetry.
  • the screw cap is provided with auxiliary channels directed from two sides against the omnidirectional jet.
  • a spring 18 presses on the pin head via a pin 19.
  • the nozzle needle 8 By pivoting a lever 20 in the direction of the arrow about an axis 21 and pivoting a driving fork 22 which is coupled to it and engages on the back of the needle head 10, the nozzle needle 8 can be retracted against the spring 18 and thereby the nozzle outlet opening 7 of the spray can can be released.
  • a needle valve in the connecting channel from the feed line 4 to the spray head 2 is also opened, preferably with a certain advance, so that the compressed air flow starts even before the spray nozzle opens.
  • the spring 18 and the bolt 19 are arranged in a special housing part, the so-called closure cap 24, which can be folded down and which can be pulled off and folded down on a rod 25 with limit stop from the front housing part or gun body 1.
  • the cap is provided with a handle 27.
  • the closure cap 24 is secured in its working position by a stretch connection with plug pins 28 which engage in holes in the gun body 1 and a locking with a clamping lever 29.
  • the construction corresponds to that of conventional spray guns (see e.g. DE 2 412 743).
  • the entirety of the parts enclosing and guiding the spray medium, consisting of the tank container 3, the spray nozzle 6 including the nozzle needle 8 and a connecting channel 30 in a web 33 between the reservoir 3 and the spray nozzle 6 is designed to be easily replaceable as an element.
  • the gun body 1 is provided with a slip shoe-shaped seat 32 for the element 31, and the transition from the tank 3 to the spray nozzle 6 is designed as a foot 33 (with sole and heel 35) which can be inserted into the seat 32.
  • a pin 36 of the closure cap 24 engaging in the heel 35 serves to secure this foot in the working position.
  • nozzle 6 and web 33 with connecting channel 30 are made in one piece.
  • the nozzle needle 8 is - fixed in the closed position, but retractable when used - in the nozzle 6. After the work is finished, the element 31 is thrown away, possibly also returned to the supplier for cleaning and reuse.
  • the tank 3 for the plastic K is provided with a small chamber 59 for the hardener to be introduced into the plastic before use.
  • the tank also contains a mixer 46/47 for plastic K and hardener H, consisting of a perforated disc 46 with a shaft 47.
  • the nozzle needle is provided with a piston 50 which, in the rest position, closes the connecting channel 30 between the tank 3 and the spray can 6 and, in the retracted working position, keeps the passage opening provided for the rear of the nozzle needle closed to the outside.
  • the spray nozzle 6 is provided on the outside with a frontal collar with which it abuts against a stop with the gun body 1.
  • the tank 3 is a commercially available cylindrical can with a lid 61 and a bottom 62.
  • This can is filled with paint, in particular plastic paint (without hardening agent), and is introduced as a separate insert into a sealing seat 60 of the gun.
  • This seat 60 is located at the entrance of the connecting channel 30, which together with the spray nozzle 6 and its needle 8 forms the foot.
  • the foot at the entrance of the connecting channel 30 is provided with a funnel-shaped cup 58, which, when placed upside down, is placed on the open tank from top to bottom.
  • the hardening agent is introduced into the paint can by emptying the tube 64.
  • the mixer handle (not shown in the drawing) is inserted, and after tearing the tear seam 70 in the flange 68, the mixture of paint and hardener is applied by and caused movement of the mixer.
  • the bottom is curved inwards so that the end of the shaft does not protrude beyond the flat boundary surface of the cylindrical box.
  • Fig. 5 shows an embodiment with a mixer, which is provided with a separate shaft (not shown in the drawing), the introduced through an insertion 77 with tear seam 78 and can be coupled to the perforated disc 46 in the bowl 58.
  • FIG. 5 also show means for locking the needle 8 in the nozzle 6 in its closed position, for example by a bolt 76a in FIG. 5 on the underside of the perforated disk 46, which engages in the groove 75 of the needle 8.
  • the bolt 76b is connected to a lever arm 82 which protrudes from the nozzle body and is released when the element 31 is inserted, so that it releases the nozzle needle for actuation with reciprocation under the influence of the spring 18 of the gun.
  • a bolt 76c is attached to a lever arm-like projection 83, which is released to release nozzle needle 8 by a pin 36 of the cap 24.
  • paint cans of other designs especially of the lid and bottom, such as. B. with a lid 61, which, as shown in FIGS. 11 and 12, are provided with a ring pull closure 67.
  • the foot 33 could also be firmly integrated into the gun body, as in multi-colored spray guns.
