Description

    Technical field
  • The invention relates to a device and method for handling at least one hose.
  • Background art
  • A fuel dispensing unit, such as a petrol pump typically comprises a pump part standing on the ground, a display part positioned above the pump part and showing the chosen type of petrol, cash readout, volume readout etc., and a column or frame to which one or more petrol hoses are connected.
  • When the tank of a vehicle is to be filled up, the driver parks the vehicle beside the petrol pump and opens the cover or cap of the petrol tank. The driver then selects the desired type of petrol and places the pump nozzle in the inlet of the vehicle's petrol tank and puts in the desired volume of petrol.
  • A difficulty that may arise in connection with filling-up is that the hose does not reach to the vehicle if parked a distance from the petrol pump. The reason why the vehicle has not been parked sufficiently close to the pump may be difficulty in maneuvering owing to a limited space round the petrol pump. To allow the hose to reach the vehicle, it is usually necessary for the driver to park his vehicle so that the side of the vehicle where the filler cap is positioned faces the petrol pump. It is not always known to a driver of an unfamiliar vehicle whether the filler cap is positioned on the left or right side. This may result in the driver by mistake parking the vehicle on the wrong side of the pump and thus not being able to fill up the tank without moving the vehicle to the other side of the petrol pump since the hose does not reach all the way round the vehicle.
  • One way of facilitating access to the petrol pump is to provide it with a longer hose. This may, however, cause problems since a longer hose may tend to land on the ground when not used and thus get stuck in or be damaged by passing cars or other vehicles. To prevent this, the fuel dispensing unit may be provided with some kind of returning mechanism for the hose.
  • US 6 328 060 discloses a gasoline dispensing unit and method according to which one end of a cord is attached to a dispensing hose to support the hose relative to a dispenser unit during non-use. The other end of the cord is attached to a drum having a tapered outer surface and a continuous spiral groove. When the hose is not in use, the cord is wound on the drum from the largest-diameter drum portion to the smallest-diameter portion. The cord thus unwinds from the drum from its smallest-diameter portion to the largest-diameter portion when the hose is pulled from the housing to provide a mechanical advantage and reduce the required pulling force.
  • GB 782 882 discloses a swinging arm hose retriever for fluid dispensing apparatus. The hose of the fluid dispensing apparatus is retracted by a spring drum which, together with a spring-biased swinging arm, is mounted on a cover replacing the normal cover for the usual aperture in the top of the dispensing cabinet. The cover carries a support from which a spindle and a frame carrying the arm are supported by bearings. A spring connected to a fork pivoted to the spindle biases the arm to its normal position.
  • A problem common for the hose returning devices described above is their size, or their extension within the fuel dispensing unit, which results in bulky and complicated structures.
  • Another problem with the hose returning devices existing of the market today is that the force required for extracting the hose from the hose housing is quite extensive.
  • A device according to the preamble of claim 1 is known from EP 0 647 587 A1 .
  • Summary of the invention
  • It is an object of the present invention to provide an improvement of the dispensing units according to prior art. A particular object is to provide a space efficient device for handling a hose of a fuel dispensing unit.
  • The invention consists of a device according to claim 1.
  • This is advantageous in that an extremely space efficient device for hose handling is provided, which device enables a smooth and flexible handling of the hose. Further, due to the intelligence of the device, the handling of the at least one hose from a customer perspective is highly facilitated.
  • The sensor means comprises a first sensor arranged in the hose storage space and configured to detect the idle position the first hose guiding means, and a second sensor arranged in the hose storage space and configured to detect the working position the first hose guiding means.
  • The control unit may be configured to trigger extraction of the cable element by means of the motor or to trigger a neutral state of the motor when the working position of the first hose guiding means is detected, and to trigger infeed of the cable element by means of the motor when the idle position of the first hose guiding means is detected.
  • The control unit may be configured to trigger extraction of the cable element by means of the motor or to trigger a neutral state of the motor when at least a portion of the first hose guiding means is detected outside of the hose storage space, and to trigger feeding in of the cable element by means of the motor the first hose guiding means is detected inside of the hose storage space.
  • The first hose guiding means may comprise a rocker unit which, to allow pulling out and returning of the hose, is pivotable in relation to the hose storage space about a pivot axis and which comprises a hose supporting part which is arranged at a distance from the pivot axis and adapted to support the hose.
  • The rocker unit may be adapted to be pivoted in the first direction when pulling out the hose and, when returning the hose, be pivoted by a rocker returning means, which applies a returning force on the rocker unit at a distance from the pivot axis in the second direction which is opposite to the first direction.
  • The rocker returning means may comprise a spring element.
  • The first hose guiding means may comprise a rail element to support the hose which, to allow pulling out and returning of the hose, is movable in relation to the hose storage space between in the idle position and the working position.
  • The rail element may be adapted to be moved towards the working position when pulling out the hose and, when returning the hose, be moved towards the idle position.
  • The sensing means may further comprise a further sensor configured to detected movement of the second hose guiding means, and the control unit is configured to stop the motor when the second hose is in a bottom position within the hose storage space.
  • The extraction of the cable element by means of the motor may be conducted for a predetermined length of the cable element.
  • The extraction of the cable element by means of the motor may be based on a motor driving power calculated by the control unit.
  • According to a second aspect, these and other objects are achieved, in full or at least in part, by a fuel dispensing unit for refueling a vehicle, comprising at least one device according the feature described above.
  • According to a third aspect, these and other objects are achieved, in full or at least in part, by a method according to claim 12.
  • Anywhere between one and ten hoses may be handled by the device according to the invention.

The device 9 will now be described in greater detail according to one exemplary embodiment in view of Fig. 3 and 4.
  • Fig. 3 and Fig 4 illustrate the device 9 when in an idle position and when in a working position. The device 9 comprises a first hose guiding means 10 and a second hose hose guiding 11, which are both movable between an idle position and a working position to control extraction and infeed of the at least one fuel hose 7, a sensor means 12 arranged in hose storage space 2, a motor 13 connected to the second hose guiding 11 means through a cable element 14, and a control unit 15 connected to the sensor means 12 and to the motor 13. The control unit 15 is configured to control the motor 13 based on signals relating to the movements of the first hose guiding means 10 and/or the second hose guiding means 11 detected by the sensor means 12.
  • The sensor means 12 comprises a first sensor 16 arranged in the hose storage space 2 and configured to detect the idle position the first hose guiding means 10, and a second sensor 17 arranged in the hose storage space 2 and configured to detect the working position the first hose guiding means 10.
