  • the applicant wanted to improve the loading mechanism in order to avoid incorrect handling of the thumbwheel which may cause re-entry of material in the device and jamming thereof.
  • the requester wanted to create a control of the mechanism and the distribution of the material to prevent the device from being shut down by a jam causing obstruction and stopping operation of it.
  • the loading wheel is arranged with a non-return device, of the freewheeling type, allowing the exit of the material out of the apparatus in normal operation and according to a appropriate direction of rotation on the one hand, and on the other hand by disconnecting said freewheel of the thumbwheel during its reverse rotation, causing the removal of the displacement of the material inside of the device.
  • the dispensing device is referenced as a whole by (A) and comprises, in known manner, a wall fixing housing (1) with a bottom wall (1a), two lateral flanges (1b), an inclined base wall (1c) and a cover (2).
  • the lateral flanges receive the axes with free rotation (3a) of a drum (3) including a cutting blade (4a) of the device cup (4) which is integrated in said drum and capable of movement movement outside the drum thanks to a mechanism loading including an eccentric, a return and launch spring associated with one of the flanges (1b) of the casing.
  • said drum (3) is associated with a safety roller (8) arranged in the part bottom of the device at the outlet of the casing, by being connected to each other by a transmission belt (7) penetrating into fitted grooves (3c) - (8a) on the drum and on the safety roller.
  • This belt (7) ensures in particular the guiding of the material towards the exit of the device.
  • the reel of material (B) is mounted between the fixed flanges of the device or flanges tilting as described in the previous patents of the applicant.
  • the cutting mechanism known per se comprises a blade (4a) associated with an articulated blade holder (4b) which allows it to exit the drum in the rear part of the device during the pulling effect of the end of the strip of material by the user.
  • This traction exerted which can vary depending on the force exerted by the user, can cause a return effect of the drum then causing the formation of a loop of material.
  • the device includes a device charging device ensuring the drum rotation control.
  • This device comprises a profiled plate (10) which is mounted pivoting on one of the flanges (1b) of the housing.
  • This profiled plate (10) has a tubular seat (10a) which is capable of engaging around a bearing (12) formed directly on said flange (1b), and allowing itself the insertion of the end (3a) of the axis of the drum (3) above.
  • This profiled plate (10) also has a flat part in the form of angular sector (10b) of the order of 70 to 100 ° and located perpendicular to the axis of the drum, to come opposite the flange or lateral flank (3d) of this latest.
  • the number of dwellings (10c) is at least two with three protruding shapes (10d) distributed over the corresponding area of the sector aforementioned angular.
  • the depth of said housings is such that it allows inserting and holding the above-mentioned means (13) in position.
  • Said sector (10b) is also arranged, in its upper part (10e) with a projection advantageously additional in curvilinear and coaxial arc within reach tubular (10a) formed on the aforementioned part (10).
  • This arch-shaped projection presents a song (10f) whose function will appear later.
  • the device's charging mechanism includes a set of pinions which are shown in particular in FIG. 2 of the drawings.
  • a wheel (20) of loading is thus mounted on an axis (21) integral with the flange of the device.
  • This wheel is shouldered and has a first crown (20a) which is likely to spill out of the device significantly to allow its manipulation by the operator.
  • This wheel includes axially a second ring (20b) of smaller diameter which cooperates with an intermediate pinion (22) mounted on a rotating pin (23) on the flange (1b), said intermediate pinion (23) cooperating with a toothed crown (24) mounted at the end of the axis (3a) of the drum (3).
  • the loading wheel comprises a non-return device (DA) fitted from the crowns (20a) and (20b). More particularly, the first ring (20a) of the wheel (20) is fitted on its interior side with a cylindrical seat (20c) on the edge of which are arranged projections (20d) four in number by example, and thus arranged radially around said bearing. These projections (20d) are thus profiled with a hook end (20e) forming a stop, with a face (20h) perpendicular to the span (20c). The projections present a ramp (20f) which is established between the base or generator of the span and the protruding end of the hook part.
  • DA non-return device
  • Each of said ramps does not lead directly to the right side (20h) of the hook part of so as to define a support zone (25) receiving a means of ball type bearing (26). Additionally, is formed on the face inner receiving of the wheel, a recess (27) allowing position and center the corresponding ball. So in this embodiment, the crown (20a) receives four projections and therefore four balls.
  • the second ring (20b) is associated and freely mounted on the ring (20a).
  • the crown (20b) has a central opening (201) engaging on the bearing surface (20c) and the corresponding projecting zones (20d), so as to be able to rotate freely relative to the crown (20a).
  • this ring (20b) has internally a profiled cavity (20m) which is capable of coming to engage around the bearing surface (20c), projections (20d) and balls (26).
  • Said cavity (20m) is thus internally profiled to constitute a raceway for the balls, allowing during the drive of the wheel, either their exhaust to operate in freewheeling mode in correspondence with a return movement of the wheel, or in causing the abutment of the balls against the projecting faces (20h) and hooks, during the rotation of the wheel in the right direction, in view of the exit of the strip of material.
  • said cavity (20m) has ramps (20n) extending outward and opening into a hollow housing (20p) receiving the balls.
  • Said crown (20b) is in turn mounted on an axis integral with a flange (1b) of the device.
  • the non-return device incorporated in the thumbwheel (20) composed of the crowns (20a) (20b), allows the actuation of the latter in the right direction the exit of the strip of material. outside the device with the meshes as provided in patent FR 00 03748.
  • the freewheel thus constituted by the specific arrangement of crowns (20a) and (20b) suppress any action of return of the band of material inside the dispenser.
  • the proposed solution is therefore simple and brings a real advantage in reducing the risk of jamming inside the device, and therefore reducing maintenance checks.
