Definitions

  • the invention relates to a hose reel according to the preamble of claim 1.
  • Hose reels for example, are arranged next to one another in paint shops for winding up several hoses, it being possible for different types of media required for painting to be supplied via the hoses.
  • the hose drum is loaded by a return spring in the winding direction.
  • the return spring is housed in a separate housing. So that the hose drum can be secured against turning back, pawls are provided on it, which can engage in corresponding recesses in locking bodies which are fastened to the housing. Due to the positive rotation lock using the ratchet mechanism, the hose drum can only be secured against rotation in the winding direction in certain positions.
  • the pawls cause considerable Noise.
  • the pawls and the plate-shaped locking body are subject to considerable wear.
  • the pawl mechanism and the separate housing for the return spring lead to a considerable design effort of the hose reel.
  • a roll-up device for cables (DE-A-34 28 412) in which the cable drum is frictionally secured against rotation by means of a brake wedge.
  • the brake wedge engages on a brake ring protruding from the cable drum.
  • the brake wedge is provided on an annular support body, the axis of which is eccentric to the axis of rotation of the cable drum.
  • the cable drum itself is loaded by a return spring in the winding direction.
  • the invention has for its object to design the generic hose reel so that it is compact, ensures low-noise operation and allows any extension length of the hose.
  • the hose drum can be frictionally secured against rotation in the winding direction by means of the brake element and the brake ring.
  • the hose reel can be secured in any desired rotational position.
  • the hose reel can be turned without noise.
  • the braking device is exposed to almost no wear.
  • the brake ring is not only used for The hose drum is secured against rotation, but at the same time also forms a limitation of the receiving space in which the return spring is accommodated. It lies in the area between the brake ring and the axis on which the hose drum is rotatably mounted. No separate housing is therefore necessary for the return spring, as a result of which the structural design of the hose reel according to the invention is extremely small.
  • the hose reel according to FIGS. 1 to 3 has a narrow, rectangular housing 1 in side view with an axis 2, which preferably runs centrally and perpendicular to the housing sides 3 and 4 (FIGS. 1, 2).
  • the flanges 6 form a lateral boundary for the hose 39 when it is wound on the hose drum 5.
  • a brake ring 7 (FIG. 3) projects axially outward over one flange 6 and is connected to the hose drum 5 in a rotationally fixed manner.
  • the hose reel 5 is fastened on a bearing ring 8 (FIG. 2), preferably on that facing away from the housing wall 4 Welded side next to a return spring 9.
  • the bearing ring 8 is seated with the interposition of a bearing 10 on a tapered end section 11 of the axis 2.
  • the bearing 10 is axially secured between a radial flange 12 of the bearing ring 8 and a snap ring 13 arranged in a circumferential groove of the bearing ring 8.
  • the return spring 9 is attached at one end to the axle 2 fixed to the housing. The other spring end is attached to the hose reel 5 or to the brake ring 7.
  • the return spring 9 is designed as a spiral spring, which is tensioned when the hose 39 is unwound and thereby loads the hose drum 5 in the winding direction.
  • a ring housing 14 sits on the axis 2, which is firmly connected to the hose drum 5 and the bearing ring 8 and rotates on the axis 2.
  • An annular channel 19, 21 is sealed with seals 17, 18.
  • Disc-shaped retaining rings 15 and 16 secure the seals 17 and 18 in the axial direction.
  • the axis 2 has a circumferential annular groove 19 which is preferably approximately half the width of its wider axis section 20 which supports the ring housing 14.
  • the annular groove 19 is aligned with an annular groove 21 in the ring housing 14, which together delimit an annular channel through which the hose 39 can be supplied with medium.
  • the hose is attached (in a manner not shown) to the ring housing 14 in such a way that the respective medium passes from the ring housing 14 into the hose.
  • FIG. 2 there is an axial blind hole shown in dashed lines in axis 2 or axis section 20 22 provided. It is connected to the annular channel 19, 21 via a radial bore 23. The medium to be discharged with the hose is supplied via the blind bore 22, the radial bore 23, the ring channel 19, 21 and a further radial bore 24 of the ring housing 14 opening into it.
  • a braking device 26 is arranged adjacent to its narrow housing end wall 25, which has a brake wedge 27 which interacts with the brake ring 7.
  • the braking device 26 has a pneumatic cylinder 28 for unlocking the braking device.
  • a compressed air line 29 opens into the cylinder 28, via which compressed air can be supplied in the direction of the arrow P.
  • a piston 30 of the pneumatic cylinder 28 can cooperate with an adjusting screw 31 of a slide 32, which is supported at its upper end via a compression spring 33 on an upper narrow housing wall 34. With the adjusting screw 31, the position of the brake wedge 27 can be adjusted very precisely so that on the one hand it brakes the hose drum 5 reliably, but on the other hand it can be properly adjusted to its release position with the pneumatic cylinder 28.
  • the brake wedge 27 is fastened to the slide 32 and is guided in its up and down movement in a guide 35 fastened to the housing walls 3, 4.
  • a handle 38 is arranged in the region of its lower end 37 and protrudes outwards through a longitudinal slot (not shown) in the wall 25.
  • the hose drum 5 When unwinding the hose, the hose drum 5 is rotated in the direction of arrow A 'against the force of the return spring 9, which is tensioned here. Since the braking surface 36 of the brake wedge 27 increases in the unwinding direction A ', the brake wedge 27 experiences a force directed against the force of the compression spring 33 as a result of its contact with the brake ring 7 of the hose drum 5. As a result, the hose drum 5 can be easily rotated in the unwinding direction A ', the brake ring 7 sliding along the braking surface 26. As soon as the hose 39 is released, the tensioned return spring 9, which attempts to rotate the hose drum 5 in the winding direction A, takes effect. However, this is prevented by the braking device 27.
  • the brake wedge 27 or the slide 32 is pressed by the spring 33 in Fig. 3 down against the brake ring 7, whereby in conjunction with the in the unwinding direction A 'increasing braking surface 36 prevents further rotation of the hose drum 5 in the winding direction A.
  • the hose 39 can only be rewound onto the hose drum 5 when the braking device 26 is moved from the locking position shown in FIG. 3 into its release position.
  • the slide 32 must be moved in the direction of the arrow P against the force of the compression spring 33, the brake wedge 27 being guided in the guide 35.
  • the tensioned return spring 9 can then rotate the hose reel 5 in the winding direction A, so that the hose 39 is wound onto the hose reel.
  • the slide 32 with the brake wedge 27 can be moved manually into its release position using the handle 38 or by means of the pneumatic cylinder 28. After winding the hose onto the hose drum 5, the handle 38 can be released or the pneumatic cylinder 28 can be vented; the slide 32 is automatically moved under the force of the compression spring 33 in Fig. 3 downward in the direction of arrow P 'in its locking position. Here, the hose drum 5 is held in its respective position, so that the hose remains in its wound position.
  • the hose 39 protrudes through an opening 44 sealed to the outside in the narrow end wall 40 opposite the end wall 25.
  • the housing side wall 3 has an assembly opening 41 through which the respective operator can reach into the housing when assembling the hose reel.
  • a feed line 42 for the medium to be discharged with the hose 39 protrudes into the axle section 20 of the axle 2.
  • the housing is extremely narrow, so that the cable reel takes up little space. This allows several such hose reels with the smallest distance in a row next to each other on a wall or the like. to be assembled.
  • the hose reel is suitable for discharging all types of paint, such as clear coats, water-based paints and other media that can be used in a paint shop, such as fillers, hardeners, spray air, breathing air, thinners and solvents.
  • the hose reel is not only suitable for wall mounting, but also for ceiling and floor mounting. It is also extremely easy to maintain and has the advantage that the hose 39 can be rolled up and down continuously.
  • the hose reel 5 can be braked without impact, which ensures quiet rolling up and unrolling. In particular, this contributes to the fact that the brake wedge 27, when the hose drum 5 rotates - in contrast to a ratchet wheel mechanism as a braking device - does not produce any noise, or at most only a very quiet one.
  • the closed design of the housing 1 has the advantage that the hose drum and the other parts of the device are housed protected from contamination.
