Definitions
- the present invention relates to a hose package arrangement with a hose package for a welding apparatus according to the preamble of claim 1.
- Hose packs of the aforementioned type are used as a transfer device between the handling part of a welding device, ie the so-called welding torch, and the actual welding unit, which essentially serves to generate welding current and to store or connect the welding media, such as the welding wire and the protective gas.
- the hose package as a transfer device is primarily the task to ensure the power and media supply over the distance to the welding unit without affecting the handling of the welding torch.
- Hose package on the one hand must not hinder the complex kinematics of the superimposed movements of the Roboterarmglieder and on the other hand, the mechanical loads of the hose assembly occurring in connection with the movement of the robot arm should be as low as possible in order to minimize wear as possible.

- the channel wall of the guide channel has a spiral spring arrangement with at least one spiral spring winding.
- the guide channel is thus designed to be sufficiently torsionally rigid in order to largely prevent harmful loading of the outer insulation or of the conductor arrangement by torsional stresses.
- the support structure has a tubular support which is provided with a torsion-resistant reinforcement.
- the carrier essentially has the task of forming the reinforcement into a tubular wall.
- the carrier can be formed from a plastic tube.
- the one torsionally rigid envelope in the form of a mesh or network, for example of a metal or a sufficiently rigid, in particular pressure-resistant non-metallic material having.

- the spiral spring arrangement itself as an electrical conductor arrangement to allow a minimized configuration of the hose package to a minimized diameter of the hose package.
- the hose package is axially displaced in one of force introduction devices.
- limited transmission portion of the coil spring assembly in the relaxed state an annular gap between the coil spring assembly and a channel wall of a receiving channel is formed, not only a relief of the insulation of a torsional strain, so reducing the torsional stress can be achieved, but depending on the dimensions of the annular gap in the maximum case complete decoupling the insulation tube from the recorded by the coil spring assembly torsional load.
- the channel wall is formed by the conductor arrangement.
- an insulating cover of the spiral spring arrangement or an insulating lining of the conductor arrangement is provided in the annular gap.
- the hose pack is provided at its wire feed end with a connecting piece which serves both for power transmission and for introducing force between the welding unit or the wire feed device and the hose package.
- a connecting piece which serves both for power transmission and for introducing force between the welding unit or the wire feed device and the hose package.
- the hose assembly according to the invention has the features of claim 1 1.
- the hose package arrangement according to the invention is provided at its wire feed end with a coupling device which has a plug part formed by the connecting piece, which can be rotated in a fixed manner. standing socket part is added for connection to a wire feeder. Due to the coupling device, which is arranged at the wire feed end, so the end of the hose assembly, which is remote from the robot wrist, results in a heat dissipation from the robot wrist obstructing, defined by the coupling device heat transfer resistance only at the end of a defined by the hose package heat transfer path, so that a significant improved heat dissipation of the heat generated at the welding torch is possible than when installing a rotary joint in the area of the robot wrist.
- the socket part has a housing part designed as an electrical conductor arrangement, which has a coupling element in an annular gap formed between the plug part and a sleeve receptacle, which serves both as a radial bearing and for current transmission, then in cooperation with the plug part in the area of the rotary coupling realized particularly good heat transfer.
- FIG. 1 shows a welding robot with a hose package arrangement arranged on the robot arm
- FIG. 2 the hose package arrangement used on the welding robot shown in FIG. 1 in a detail view
- FIG. 3 the hose package arrangement shown in Figure 2 in a partial sectional view along section line III - III. 4 shows an enlarged illustration of a distal connection end corresponding to section IV of the hose package arrangement shown in FIG. 3;
- FIG. 5 shows an enlarged view of a proximal connection end corresponding to section V of FIG.
- FIG. 1 shows a welding robot 10 with a body part 12, which can be pivoted about a vertical axis 1 1, on which an articulated arm 13 is arranged.
- a robot wrist 17 pivotable about a wrist axis 16 which hingedly connects a burner base 18 of a welding torch 19 to the lower arm member 15.
- a hose package 21 is connected, which extends from the connecting element 20 and the burner base 18 to a formed at a proximal end 31 of the hose package 21 coupling device 22, the connection the hose package is used on a wire feed device 23 designed here as a wire feed case.
- Hose packet 21 and the coupling device 22 formed hose assembly 24 connected indirectly via a connecting element 25 to the wire feeder 23.
- FIG. 2 shows the hose package arrangement 24 with the connection element 20 arranged at the distal end 14, which in the present case is referred to as
- Sensor device is formed, which has a force sensor not shown here, to initiate a collision of the welding torch 19 with a workpiece, a suitable evasive movement of the welding robot 10. Notwithstanding the illustration of the hose However, ket onion 24 in Fig. 2, it is also possible to connect the distal end 14 of the hose assembly 21 directly to the burner base 18.
- the hose package assembly 24 shown in FIG. 2 is used to supply power and media to the welding torch 19 and, as shown in FIG. 3, has a guide channel 26 in the hose assembly 21, which is primarily used to carry one from the wire feed device 23 into one Burner head 27 (Fig. 1) of the welding torch 19 promoted, not shown here welding wire and also serves to promote a protective gas.
- the hose package assembly 24 shown in Fig. 2 here a hose package 21 enveloping the conduit 28, which serves to guide electrical signal lines 29 or media lines not shown here, for example, for the guidance of cooling water.
- FIG. 3 shows a connection end 30 formed at the distal end 14 of the hose package 21 and a connection end 32 formed at a proximal end 31 of the hose package 21, which are arranged on both sides of a transfer section 52 of the hose package 21, in a sectional view.
- a channel wall 33 of the guide channel 26 is defined by the coaxial arrangement of two spiral spring coils 34, 35 which together form a coil spring assembly 36.
- the spiral spring windings 34, 35 are provided with opposite sense of winding in relation to a guide channel axis 37, so that a support structure which is sufficiently torsionally rigid in both rotational angle directions can be realized.
- the spiral spring arrangement 36 or the outer spiral spring winding 35 is provided with a hose cover 40 formed from an insulating material, wherein the spiral spring arrangement 36 is arranged in a receiving channel 54 whose channel wall 55 is formed by the conductor arrangement 21.
