Definitions

  • the present invention relates to mechanisms for delivering pieces of paper or the like material, which are severed from a continuous source of continuous paper band, such as those used, for example, for supplying paper towels for hand drying or cleaning purposes.
  • Mechanisms for delivering pieces of continuous or band paper comprising a pair of mutually tangent pres­sure rollers are well known, wherein a first one of the said rollers is mounted rotating about a fixed axis while the other, second roller, is mounted on an oscillating frame which is spring biased against the first roller, the end of a paper band issuing from a bobbin being caught be­tween both rollers, the mechanism further comprising a locking device associated to the shaft of one of the rol­lers and restricting the length of paper which is delivered each time that a pull is applied to the paper band end, a timing device holding the mechanism locked during a restricted period, and a device operating one of the rollers once a paper band length has been withdrawn, to eject a short band length to make its grasping easier, the ensemble being located within a box provided with a paper outlet opening.
  • a mechanism of the above features makes the sub­ject of the Spanish Utility Model N o 290 203 of which the applicant is the owner.
  • the device automatically supplying a short paper length once a user has taken out the band and detached a length of it corresponding to a towel or the like dose acts directly upon the shaft of one of the band drawing rollers by means of a cam biased by a spring which is released under the control of a timing system and which is loaded through a reducing transmission connected to the shaft of the said roller.
  • a cam biased by a spring which is released under the control of a timing system and which is loaded through a reducing transmission connected to the shaft of the said roller.
  • the triggering of the mechanism supplying the short paper length operates in two steps with a short time period be­tween these latter, which may induce the user to apply a pull on the paper band in order to obtain a new dose, in the wrong timing thus causing the mechanism to become blocked.
  • the device for restricting the length of the delivered paper had provision for delivering paper pieces of different lengths according to the needs of the user.
  • the device for cutting the pulled paper band can also be subject of improvement with a view of simplifying its conformation though with no loss in efficiency.
  • the present invention have been devised to provide higher per­formances of the mechanism.
  • the spring loading cam of the ejector device for delivering the short paper length when the mechanism has been unlocked is mounted fixed on the shaft of a set of sprockets having different diameters and adapted to be selectively engaged by a set of different diameter sprockets secured to the shaft of one of the paper band drawing rollers.
  • the ejector device and the timer winding device which are of a common construction, are mounted on the same shaft of the set of sprockets selec­tively meshing with the sprockets mounted in a position which is displaceable at will on the shaft of one of the paper band drawing rollers.
  • the oscillating sup­port carrying mounted thereon the movable roller is formed with an arcuate gutter or ramp located immediately under the opening through which the paper band coming from the supply bobbin issues, the said gutter or ramp receiving the engagement of one end of springs having their opposite ends anchored in fixed points of the support structure of the mechanism, thus forcing the supported roller to rest onto the other roller.
  • the border of the paper exit opening formed in the enclosure containing the mechanism has a cutting edge, which can be toothed, for cutting the withdrawn paper band.
  • the continuous paper delivery mechanism consists, in the drawings, of two rollers 1,2 trapping a paper band 3 coming from a bobbin 4 located within a container 5, the bottom of which is shaped as a funnel 6, according to a known embodiment.
  • the roller 1 is mounted on an oscillating sup­port 7 provided with wings 8 which are articulated about a shaft 9 mounted on fixed lugs 10.
  • This oscillating support 8 is biased by springs 11 having one end anchored to the fixed lugs 10 and the opposite end resting upon the back of an arcuate gutter or ramp 12 extending upwards of the support, thus forming a guide for the paper band 3 at the outlet of this latter from the funnel 6 (Fig. 3).
  • a conventional escapement device formed of a sprocket 13 against which a tooth 14 impinges under the biasing of a spring 15 to prevent the back motion of the roller 2, is mounted at one end of the shaft 2a of the said roller 2.
  • the opposite end of the shaft 2a has mounted thereon two sprockets 16,17 having different diameters and adapted to mesh selectively and alternatively with two sprockets 18,19 which are fast with a shaft 20 mounted for rotation on a support 21.
  • the same shaft 20 has secured thereon a cam 22 with a spring 23 constituting the automatic feed device of the shaft 2a for the delivery of a short run or length of the band 3.
  • This delivery device is associated, according to a known embodiment, to a timer device formed of two mutually faced suction cups 24,25 of which the cup 24 can be displaced by a movable arm 26 in turn operated by a cam 27 joined to the shaft 20 of the sprockets 18,19.
  • the described mechanism is housed in a pan 28 having an opening 29 for the outlet of the band 3a and formed with a toothed wing 30 for severing the delivered band.
  • toothed cutting edge 30 instead of a cutter blade joined by conventional means to the structure which the mechanism is secured upon, for severing the delivered band run 3a.
  • This cutting edge 30 may be obtained directly integral with the pan 28, or by inserting on this latter a stiffer part, either of plastics or metallic material.
