Definitions

  • a dispenser for textile hand towelling web which includes a motor driven dispensing roller for withdrawing fresh hand towelling from a supply and dispensing this fresh hand towelling, and a motor operated retracting device for drawing used towelling into the housing of the dispenser.
  • the retracting device is also operable in a reverse direction for dispensing used towelling from the housing.
  • a braking flap is provided which is adjustable between an effective position in which it serves to smooth and tension the used hand towelling travelling to the retracting device, and an ineffective position in which it is released from the used towelling.
  • a programming control arrangement controls the operation of the two motor drives as follows.
  • a first part length of fresh hand towelling is dispensed by the dispensing roller.
  • a dog or cam coupled to the dispensing roller shifts an adjusting thrust rod which in turn moves the braking flap into its ineffective position.
  • the retracting device is operated in said reverse direction for dispensing a length of used hand towelling.
  • the dispensing roller dispenses a second part length of fresh hand towelling and restores the braking flap to its effective position.
  • the two motor drives are then held at rest for a predetermined period during which the user can dry his hands on the loop of towelling now hanging out of the housing.
  • the retracting device is operated for drawing the used hand towelling into the housing.
  • the retracting device may be temporarily stopped under overload, but the programme end can only be reached and a new operation started when at least a predetermined length of used hand towelling has been drawn in and the hand towelling has thereafter been tautened.
  • a dispenser for hand towelling webs which includes a reel of fresh hand towelling and a reel of used hand towelling, that the hand towelling shall be held in a taut condition over the underside of the housing when the parts are at rest in a condition ready for use.
  • Dispensers for hand towelling webs of this nature are known.
  • this flap shall be taken out of the path of the hand towelling when dispensing is required so that it does not interfere with the operation.
  • roller for the issuing of fresh hand towelling and a retracting device for the dispensing and retracting of used hand towelling by electric motor means.
  • the object of the present invention is to-provide a dispenser for hand towelling webs with simple and reliable control means for the driving motors and for the adjustment of a hand towelling braking flap.
  • the subject of this invention is a textile hand towelling web dispenser comprising a housing to accommodate a supply of fresh hand towelling from which hand towelling can be withdrawn and dispensed from the housing through the agency of a gnotor driven dispensing roller, and comprising a retracting device, likewise motor operated, for drawing used towelling into the housing, this retracting device also being operable in a reverse direction to dispense used hand towelling from the housing, including a flap for braking the hand towelling arranged to bear yieldably against hand towelling travelling to the retracting device, to divert this and to smooth and tension it, and an adjusting member which is operable to move the hand towelling braking flap out of the way of the hand towelling for the dispensing of used hand towelling and to bring it into an inactive position, characterised by a dog coupled to the dispensing roller for operating the adjusting member and a programming control arrangement with means,
  • FIG. 1 is a diagrammatic side view of a hand towelling dispenser with the side wall of the housing omitted
  • FIG. 2 is a block diagram of a control arrangement of the dispenser and FIG. 3 is a diagram to explain the operation of a switch-operating drum of the control arrangement.
  • the textile hand towelling dispenser which is illustrated in FIG. 1 comprises a housing with a rear wall I which, for example, may be fastened to the wall of a toilet, a housing'top 2, and a housing bottom 3 which is of dished form and which accommodates a fresh supply of hand towelling in the form of a reel 4.
  • the web of fresh hand towelling from the reel 4 can be dispensed from the housing through the agency ofa dispensing roller 6.
  • the path of this towelling is depicted by a chain dotted line 8.
  • the dispensing roller 6 can be driven from an electric motor 10, which has been omitted from FIG. 1 and is merely shown diagrammatically in FIG. 2, through a worm wheel 15.
  • a reel 9 of used hand towelling is disposed above and in contact with the retracting roller 7 and is impelled by this roller to draw used hand towelling into the housing and wind it up.
  • the worm wheel 21 carries a dog 22 which cooperates with a switch 23 (see also FIG. 2) and operates this once per rotation of roller 7.
  • a programming wheel 17 is coupled with the worm wheel 15 of the dispensing roller 6 through a pinion 16 with a transmission ratio of 1 z 2.5, and this wheel 17 has two dogs 18 and 19 cooperating with a switch 20 (see also FIG. 2).
  • the programming wheel 17 has an eccentric cam or dog 26 which cooperates with the leading end of a thrust rod 27 mounted for horizontal displacement on the mounting plate 5.
  • the rear end of the thrust rod 27 cooperates with an arm 29 mounted on the pivot shaft of a hand towelling braking flap 28. This flap presses against the used hand towelling, as it runs to the reel 9, between two projections 31 and 32 provided on the rear wall of the housing, under the action of a draw spring which engages the arm 29,
  • the hand towelling dispenser illustrated in FIG. 1 has a control arrangement which is diagrammatically illustrated in FIG. 2.
  • This arrangement has ten control switches S1 to S10 which are operated by a rotable drum 35 provided with cams.
  • This drum has twelve different angular positions (spaced from one another by 30) and can be brought successively into these positions by a stepping motor 36.
  • FIG. 3 shows which of the switches S1 to S10 are held closed by the cams in the different angular positions of the drum 35.
  • the stepping motor can be brought into operation through various control circuits, one of which contains a delay device 37 and another a manually operable switching de vice 38.
  • the control arrangement includes, in addition to the switches 20 and 23 mentioned above, a switch 39 which is operated by a dog on the thrust rod 27 (FIG. 1) when this is pushed rearwards by cam 26, and a switch 41 which is operated by an arm connected to the braking flap 28 when this flap is forced out by taut hand towelling between the projections 31 and 32 against the action of spring 30.
  • This switching device 38 is for example a lightresponsive unit, a proximity or contact switch, a press button or the like, and it is operated by a new user (or simply by the approach of the latter) to bring about the dispensing of hand towelling.
  • the operation of the switch-on device 38 brings into action the stepping motor 36 which turns the cam drum 35 into position 30.
  • switch 23 which, fed through switch S5, delivers a switch-on signal to the stepping motor 36.
  • the delay device 37 gives a signal to the stepping motor 36 and this turns the cam drum35 into position In position 180 the switch S1 again gives a signal to the delay device 37, and the second half of the use per-' iod then follows after which the drum is turned into the 210 position.
  • switches 85 and S9 are closed.
  • Switch S9 causes negative tension to be applied to the retracting motor 11 with the result that this i i turns the retracting roller 7 in the draw-in direction (wind up) to reel up used hand towelling on reel 9."
  • the dog 22 operates switch 23 and this, fed through closed switchSS, imparts a switch-on signal to the stepping motor 35.
  • switch S2 therefore cannot be closed and the switching device 38 cannot be activated. Activation of the dispensing motor is thus inhibited until a predetermined length of used handtowelling (corresponding to four rotations of' the draw-in roller 7, about 8/9 length of the previously dispensed handtowelling) has been drawn in and until thereafter the switch 41 operated by the tautened handtowelling emits a switch-on signal through switch S10.
  • a predetermined length of used handtowelling corresponding to four rotations of' the draw-in roller 7, about 8/9 length of the previously dispensed handtowelling
  • Switch S8 which remains closed in all positions of the cam roller 35 other than 0,only has the function when the dispenser is opened, to move on the cam drum 35 to the 0 position independently of the then prevailing phase of the programme, this in conjunction with a cover switch (not shown).
  • a dispenser for textile hand towelling web comprising:
  • a housing adapted to accommodate a supply of fresh hand towelling
  • a dispensing roller and means for driving said dispensing roller in order to withdraw hand towelling from said supply and to dispense this hand towelling from said housing
  • retracting device and means for driving said retracting device in order to draw used hand towelling into said housing, said retracting device also being operable in a reverse direction to dispense used hand towelling from said housing,
  • a towelling braking flap arranged to bear yieldably against said hand towelling running to said retracting device, to divert this hand towelling so as to smooth and tension it
  • an adjusting member which is operable to move said hand towelling braking flap out of the way of the hand towelling into an ineffective position for the dispensing of used hand towelling
  • a programming control arrangement including:
