Definitions

  • the invention relates to a reel for an elongated, flexible element, especially for a hose, cable, rope or the like, with a rotatable drum for rolling up or Unroll the element with a return device for turning the drum in the winding or unwinding direction and with an automatic brake to stop the by Return device caused roll-up or roll-off in a predetermined rotational position of the drum in which the element is rolled up to a defined remaining length or is unrolled, with the brake rotating around the drum
  • Retractor for an elongated, flexible braking element comprises, in several turns around a lateral surface the drum is wound, one end of which has a circumference connected to the drum and is dimensioned such that the When the predetermined rotational position is reached by a Tractive force in the braking element is forcibly stopped.
  • NORFI has the most advanced program Anlagentechnik "(1991) is a hose reel for Exhaust gas extraction systems known.
  • the well-known hose reel has a drum for the hose.
  • the drum is made by an electric motor, which is designed as a brake motor is.
  • the free end of the hose can be used with a suitable one Connect the grommet to an exhaust pipe of a motor vehicle.
  • the other end of the hose is fixed with a hollow axis of the Drum connected.
  • Nozzle with rotary coupling can exhaust the exhaust gas over a suitable blowers are vacuumed and disposed of.
  • the drive is also other hose reels for the above Purpose known in which a return device with a spring is provided.
  • the spring is thereby during the Unrolling the hose tensioned and with the hose unrolled locked by means of a lock.
  • To rewind the The lock is released and the tensioned spring drives the drum so that the hose is completely or is rolled up to a certain remaining length.
  • Such reels are also used by electrical devices, for example vacuum cleaners, ago known in which the power cord in this way and can be rolled up and down again.
  • the stopping the drum generally causes the hose or the cable is passed through an opening whose diameter only slightly larger than that of the hose or cable is.
  • the larger grommet or the larger plug or one for this purpose keep the sleeve pushed onto the hose then hang on this opening so that the effect the return device, i.e. the reeling movement of the drum, is suddenly stopped.
  • the known devices therefore have the disadvantage that that when the predetermined rotational position or end position is reached the drum a very high and sudden pull on the hose or the cable is exercised. This can take longer Operation lead to damage, for example Tear off electrical contacts in the transition from the cable to the plug or cracks on the grommet, from which exhaust gas escapes could.
  • US-A-1 453 999 is a reel-up known for an air hose, as it is at petrol stations or the like. is used for inflating pneumatic tires of motor vehicles.
  • the air hose is wound on a drum, whereby one end of the air hose over the drum shaft to a stationary one Compressed air connection can be supplied. The other, free end of the air hose can be unwound from the drum.
  • the drum is provided with a return spring so that the unwound air hose after completion of the inflation process can be automatically rewound on the drum.
  • a braking device is provided.
  • the Braking device includes a chain running on a peripheral surface smaller diameter of the drum assembly is wound. One end of the chain is struck on the peripheral surface.
  • the other end of the chain is led away from the peripheral surface, namely to the free end of a piston rod of a piston-cylinder arrangement, whose cylinders are fixed with the reel connected is.
  • the length of the chain is such that the Chain at the end of the winding process for the air hose is fully wound up and shortly before the end of constructively possible winding the piston from the Tried to pull out the cylinder. This way the end will be the winding process for the air hose due to the damping effect the piston-cylinder arrangement braked.
  • the known arrangement has the disadvantage that numerous complex Components are required, in particular a piston-cylinder arrangement. It also requires a considerable amount Installation space.
  • the invention is based on the object, one To further develop reels of the type mentioned at the beginning that the process with extremely simple and failure-prone means the stopping of the drum is controlled so that in itself known the delay in stopping the drum can be adjusted and the wear of those involved Elements is kept low. In this way e.g. at the Use in exhaust gas extraction systems of the very expensive because it is resistant to high temperatures Exhaust extraction system hose protected and the lifespan of the reel can be significantly extended.
  • the fact that an intervention for the expiry of Braking process exists, the described "whip effect" can be avoided by braking the drum so is carefully adjusted so that the free end of the hose or cable moves only slightly when the drum is stopped.
  • This object is achieved in that the Brake element in sections, in particular with one turn lifted from the lateral surface and around a fixed deflection point is led.
  • the invention has the advantage that a very compact Construction arises because the entire brake is made up of only one multiple coiled rope, tape or the like.
  • the Rope or the like is only in one place, namely in the area of one Winding, slightly lifted from the drum.
  • the transition from the free rotation of the drum to the braked position inevitably takes place gradually because of the shortening the free path length due to the geometric conditions also gradually takes place. It is therefore already being created then a steady, i.e. gradual braking effect when the rope or the like is inherently inextensible.
  • the arrangement is therefore extreme simple, not susceptible to faults and simple even when worn Exchange funds and without higher costs.
  • This measure has the advantage that the drum is adjustable Way can be braked even softer because when reached the predetermined rotational end position of the train in the elongated, flexible braking element further delayed to one Stopping the drum leads.
  • the Brake element a substantially inextensible cord or the like. and includes a spring switched into the cord.
  • This measure has the advantage that a mechanical one hand highly stable element such as a cord, a wire, a rope or Like. Can be used, but on the other hand, the desired Elasticity is represented by a spring, the spring characteristic can be selected in a wide range.
  • the spring is raised Section of the braking element is arranged when the drum is in the predetermined rotational position.
  • This measure has the advantage that the spring is free Can stretch and relax.
  • the Deflection point a fixed role.
  • This measure has the advantage that the braking element is practical can be guided around the deflection point without wear.
  • the braking element at the deflection point Includes angles between 50 ° and 100 ° of the lateral surface.
  • the braking element is with both The ends are attached to an attachment point on the outer surface.
  • This measure has the advantage that the braking element as a whole is easily accessible and therefore also easy when needed can be exchanged.
  • both are Fastened ends at the same attachment point.
  • This measure has the advantage that only one Attachment point is required. This will do the assembly simplified and a cheaper production is possible.
  • this is Brake element with one end at a first attachment point on the lateral surface and with its other end on a second Attachment point of an auxiliary drum struck, which in Depending on the drum is rotatable.
  • This measure has the advantage that the braking element on the Drum or the auxiliary drum each only unwound and each just being wound up.
  • This measure has the advantage that the braking element is safe is guided on the lateral surface and in the deflection point and itself cannot tangle due to the effective tension.
  • exemplary embodiments of the invention are preferred where the outer surface is also the roll-up surface for the Element is.
  • This measure also has the advantage of being particularly simple Construction because the rolling surface for the element, i.e. the Hose, the cable or the like. Is present anyway and therefore no separate components are required, though the braking element is wound onto this rolling surface.
  • hose reel designates a hose reel, as a whole it is used in exhaust gas extraction systems.
  • Such facilities are usually in manufacturing, assembly or operating halls provided in which there are motor vehicles with the engine running are located.
