Definitions

• the invention relates to a spray gun line connecting device according to the preamble of claim 1.
• Spray guns of this type are used for spray coating objects with liquid paint or liquid paint.
• Spray guns of this type are known for example from EP 1 287 901 Bl.
• a perforated plate can be achieved according to the invention the following advantages: good protection of the hose connection sockets from mechanical damage and dirt; an inexpensive and good seal, preferably by means of O-rings, on the back and on the front of the perforated plate for the supply of liquid paint or liquid paint and one or more air streams from the package of tubes in the robot arm to at least one spray gun, which of the robot arm is worn.
• the perforated plate is achieved in a simple manner an exact positioning of the seals.
• a spray gun or an intermediate body, by means of which the latter one or more spray guns are connectable to the robot arm, may be attached to the robot arm, to the robot flange or to the perforated plate, as appropriate in the practice of the invention.
• the socket collars of hose connection sockets are not provided, as in the prior art, with a polygonal, for example hexagonal, outer circumference, but with a circular outer circumference.
• a polygonal for example hexagonal, outer circumference
• a circular outer circumference As a result, smaller distances between the flange holes and thus between the hoses are possible.
• the circular shape of the bush collar facilitates the installation and removal of the hoses, as the radially protruding bush collar can be positioned in any direction without colliding with adjacent socket collar. This also allows the use of larger dimensional tolerances. 79
• FIG. 1 is a perspective view of an automatic spray gun, which is attached to a robot arm,
• Fig. 2 is an exploded perspective view of the end portion of
• Robot arm with a package of hoses and a perforated plate extending out of it
• FIG. 3 is a perspective front end view of the robot arm with the perforated plate attached thereto, which covers the hose ends pushed back into the robot arm,
• FIG. 4 is a front end view of the robot arm of FIG. 3,
• Fig. 6 shows an end portion of a hose of Fig. 2 with a plugged on him hose connection socket, which is connected to the hose, for example, is clamped to the hose.
• Fig. 1 shows an automatic spray gun 2 for spray coating objects with liquid paint or varnish.
• the spray gun 2 is attached via an intermediate plate 4 to an adapter 6, which has an adapter flange 8.
• the adapter flange 8 is fastened by means of screws (not shown) to a robot flange 10, which may be in one or more parts and is fastened by screws 12 to a tubular end portion of a robot arm 14.

• adapter 6 and intermediate plate 4 only a single intermediate element or both intermediate plate 4 and adapter 6 are omitted and the spray gun 2 are attached directly to the robot flange 10, in which latter case a housing of the spray gun 2 itself serves as an intermediate body between the hoses 20 of the robot arm 14 and the internal lines of the spray gun 2.
• the robot flange 10 is provided with a plurality of flanged holes 30, in each of which a hose connector socket 32 is inserted, which is respectively mated with the hose end of the hoses 20 and each with a radially projecting socket collar 34 at the front Flange surface 36 is present.
• the robot flange 10 may be formed in several parts and, for example, have a one-piece or multi-part flange 10-1 and a flange plate 10-2 fixed to the flange 10-1 and arranged centrally to it.

• the protruding sleeve collars 34 of the hose connectors 32 are in the face bore extension the flange holes 30 are each arranged completely sunk.
• the flange plate 10 has on its forward facing end face a, preferably cylindrical, recess 38 with a forward facing 79
• the socket collars 34 are sunk into the base surface 40, so that they do not protrude from the base to the front, but preferably terminate with it in alignment.
• a perforated plate 42 is arranged in the recess 38, which is preferably aligned with the forwardly facing end face 44 of the flange plate 10-2 in the radial direction.
• the perforated plate 42 extends radially beyond the bushing collars 34 of all the hose connectors 32.
• a plurality of through holes 46 are formed, which communicate with at least some of the flange holes 30 and thus also with the hose channels of the tubes 20, and also with the adjacent ends the holes 26 in the adapter 6 are arranged axially in alignment.

• the seals 48 on the rear side of the plate sealingly abut each other on a front end surface 52 of a hose connection socket 32 or are arranged in the disassembled state of the line connecting device such that they can be applied.
• the seals 50 on the front flange side are each in sealing contact with a rear end wall 54 of the adapter 6 (FIG. 1), each seal 50 sealingly surrounding the bore end of one of the bores 26 formed in the adapter 6.
• the seals 48 and 50 are preferably inserted into annular recesses 49 and 51, respectively, of the perforated plate 42, from which they protrude somewhat axially from the perforated plate 42, at least in the non-assembled state of the line connecting device.
