Definitions

  • the invention relates to the technical sector of dispensing devices for wiping paper such as fleece, for hand towel applications, toilet paper, wiping and cleaning in general.
  • the applicant has already developed numerous devices of this type for the aforementioned applications. These devices are of the type comprising a casing (1) with protective cover (2), said casing being arranged to receive internally a drum (3) arranged for positioning and operation of a cutting device (4).
  • a pressing element takes support on the drum, while the coil (B) of wound material is mounted on a reel holder allowing the distribution of the strip of material to the drum for cutting, after manual traction by the operator leaving the housing. Alternatively, the coil can be supported directly on the drum.
  • an appliance wiping paper tape dispenser including a tape spool of paper, a pressure roller coming into contact with the strip on the reel, and a drum with a knife to cut the strip.
  • the roller presser is articulated and pivoted by two tilting levers to come in permanent and pressurized contact with the coil by defining a distance between the stressing zones defined by the contact reel / pressure roller on the one hand, and drum / cutting blade outlet on the other hand, of the order of 25 to 50 cm.
  • the outlet of the cutting blade (4a) near the roller support presser and drum (about two to four centimeters) promotes formation of folds in the strip of material due to a lack of tension between the aforementioned support and the penetration of the blade into the material, so that the cut is not always clean and straightforward.
  • This drawback is found currently in both cases where the dispensing apparatus includes a reel of material in direct contact with the drum, or when the device dispenser includes a roll of suspended material without contact with the drum, but this contact being ensured by the pressure roller pressing on the receiving drum of the cutting device.
  • dispensers as described according to the prior art.
  • the distribution of the tape of material is braked as a result of the direct pressing of the pressure roller on the drum in particular, when the blade passes through the housing area blade exit hollow, but also in the case of a deformed drum allowing format adjustment.
  • the aim sought after according to the invention was to design a new device wiping material distributor which overcomes these drawbacks.
  • the solution provided consists in a total reconsideration of the dispensing apparatus in order to respond to the problems raised.
  • the material dispensing device is of the type comprising a casing, a cover, a drum, a cutting blade integrated into the drum, means for launching and drum recall including an eccentric and a spring for launching and reminder arranged from a lateral side of the drum, lateral flanges of the housing arranged to support the material reel, a pressure roller being capable of ensuring a pressure of the strip of material at a location given in addition to a second pressure zone defined towards the zone cutting the strip of material at the drum, the pressure roller being mounted articulated and pivotable by two tilting levers to come in permanent and pressurized contact with the material reel, defining a distance between the stressing zones defined by the coil / pressure roller contact on the one hand, and drum / blade outlet section on the other hand, of the order of 25 to 50 cm, characterized in that the two levers (9-10) are uncoupled from each other and their pivoting is independent, so that the pressure roller (8) can tilt be performed with variations of each of said levers, allowing to
  • the dispensing device referenced as a whole by the reference (A) 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-3b) of a drum (3) including a cutting blade (4a) of the cut judiciously arranged with a rack assembly (not shown) to be retracted into the drum at rest and to exit the drum for cutting the material pulled manually under the device, according to the teaching of French patents n ° 2332215 and 2779050.
  • the axis (3a) on one side of the drum cooperates with an operating button (5) accessible from the side for loading, while the other axis (3b) cooperates with an eccentric lever (6) for launching the drum which is connected by a spring (6a) associated with the flange (1b).
  • the dispensing device is arranged in the manner next.
  • the side flanges (1b) between which the drum is mounted, are extend to the top of the device to allow reception of two end pieces (7) rotatably mounted on supports (7a) integral with the part upper (1b1) of the aforementioned flanges. These tips (7) adapt to inside the material reel core.
  • the two side flanges (1b) have a capacity of separation by elastic deformation to allow insertion of the material reel (B).
  • each flange (1b) externally presents a gripping dish (1b2) allowing the operator to set them aside appreciably for the introduction and placement of the coil of material.
  • the said sear dishes are in contact with the inner walls of the hood when it is put on, so that the cover provides a support and tightening function for the flanges (1b) to better resistance of the mechanisms and components of the device.
  • a pressure roller (8) which is mounted articulated and pivoting backwards, being in contact permanent and under pressure with the material reel (B).
  • the flanges (1b) are arranged on their bitter song with a curvilinear shape (1b3) forming a guide ramp and thus allowing movement towards the rear of said pressure roller (8).
  • said pressure roller (8) comprises a longitudinal axis (8.a) whose ends (8a1-8a2) take support on the curvilinear edge (1b3) respective of the flanges (1b), overflowing substantially of these to be engaged in hook parts (9a-10a) arranged on two tilting levers (9-10) arranged on the side and other of each aforementioned flange (1b), outside the receiving volume drum, pressure roller, and loading spool.
  • Both levers (9-10) are respectively articulated at their base (9b-10b) on an axis pivot (11-12) arranged in the lower part of the flanges (1b).
  • Each lever (9-10) is associated with a return spring (13-14), one of which end (13a - 14a) is in a fixed position on the abovementioned flanges (1b) and the other end (13b-14b) on the lever (9-10).
  • the two levers (9-10) are only not coupled together so that the pivoting of the pressure roller (8) can be carried out with differentiated tilting of the two levers.
  • the pressure roller can be located with a longitudinal axis (x-x) not parallel to the longitudinal axis (y-y) of the coil (B), or of the axis longitudinal (z-z) of the underlying drum (3). This differentiation allows advantageously to marry all the imperfections of form if there are the reel of wound material thus allowing constant pressure of the pressure roller on the material reel whatever the existing deformations of the coil.
  • the maximum travel of the pressure roller (8) depending on the diameter of the wiping reel can bring it towards the bottom wall (1a) of the device, thus ensuring an angular movement which can be around 70 to 90 °.
  • one of the ends (8a) of the axis of the pressure roller (8) comprises a first deflection pulley (15) located on the inner side of the device with respect to the facing flange (1b).
  • This first pulley is capable of receiving and guiding a second belt (16) which is also guided on a second pulley (17) mounted in overflow of the drum axis (3).
  • This second pulley (17) is located thus in the radial extension of the first pulley (15) of the roller presser (8).
  • a third return pulley (18) is arranged at the rear of the device in the same plane as the previous two (16-17). This third pulley (18) is fixed to free rotation in the rear part of the flange facing, support for the spool, the drum and the pressure roller.
  • This third pulley (18) has the function of retaining the tension regular on this second guide belt (16) during the spacing towards the rear of the pressure roller due to the diameter of the spool, avoiding any rupture of the belt.
  • the two levers (9-10) are mated.
  • the maximum travel of the pressure roller (8) remains the same than that described in the first implementation. It is the same in the arrangement of the pressure roller with the various aforementioned pulleys.
  • the roller presser (8) is substantially removed from the drum (3) and thus of the contact zone of the strip of material on the drum at the place of cutting by the cutting device.
  • the distance thus obtained is variable depending on the diameter of the material reel. This distance is of the order of 25 to 50 cm depending on the diameter of said reel of material.
  • the band of material which is therefore tensioned between the different points of contacts (A1-A2) defined on the one hand by the contact (A1) coil-roller presser on the one hand, and contact (A2) drum - cutting blade outlet on the other part, is much more important than before and we see that there is no longer a zone of folds of the material as encountered previously. Said tension distance thus obtained is greater than more than one revolution of the reel when it is full.
  • a deflection roller (19) is mounted free rotating at the front of the device between the front ends (1b4) of the flanges (1b). This roller is without contact with the drum (3) and it simply allows the guiding and returning the strip of material to the drum and device for chopped off.
  • Said deflection roller (19) has a central notch (19a) allowing the passage of a third transmission belt (20) which will be specified later. On either side of this central notch (19a) are arranged smooth areas (19b) for supporting the strip of material.
  • the position of this deflection roller (19) between the flanges (1b) of the housing can be set variable in two or more zones (21a-21b) by openings made on said flanges (1b) and making it possible to distance or to bring this return roller closer to the drum (3) depending, for example of the diameter of said drum.
  • a fourth pulley (22) is disposed in the bottom of the housing while being held by a support (23) integral with the bottom face (1a) of the casing.
  • This fourth pulley (22) is located in the axial extension (P-P) on the one hand of the slot central (3c) arranged on the drum and on the other hand of the notch (19a) formed on the deflection roller (19).
  • the third belt (20) of transmission which connects the deflection roller (19) to the fourth pulley (22) considered causes it to pass over the drum (3)
  • the upper strand (20a) of the belt (20) is above the drum and without contact with this one.
  • the lower strand (20b) of the belt (20) is obliged to partially penetrate the central slot (3c) formed on the drum (3) at about an angle between 100 and 130 ° in depending on the diameter of the pulley (22).
  • the strip of material from the spool (B) is thus guided in coming towards the front of the device by the deflection roller (19) and entering the gap between said deflection roller (19) and the drum (3), the strip of material then passes under the lower strand (20b) of the third transmission belt while being firmly supported on the drum (3).
  • the lower strand (20b) of said third belt therefore comes to bear in the central slot (3c) of the drum while being in contact with the underlying belt called first belt (C1) which connects the drum (3) with the lower safety roller (RS) located near the exit slot material out of the device.
  • the support (23) of the fourth pulley (22) has a curvilinear edge (23a) facing the drum to be concentric with the periphery of the drum, and thus accompany the band material to the device outlet.
  • the distance of tensioning the strip of material pulled between the first contact (A1) resulting from the pressing of the pressure roller on the material reel and the second contact (A2) resulting from the output of the cutting blade from the drum reveals a distance greater than 25 cm, up to 50 cm when the coil is full, either in conditions far superior to art prior.
  • the pressure roller (8) is fitted internally with a specific additional tensioning mechanism.
  • the roller presser is fitted at one end with a span (8b) of larger diameter reduced likely to authorize the engagement of a telescopic axis (24) whose the end (24a) engages in the notch of the rocking lever (9).
  • the spacing of the flanges (1b) allows the disengagement of the roller presser with respect to the telescopic axis.
  • the other end of the roller presser internally has a cylindrical cavity (8c) allowing partial engagement of a nozzle (25). This tip has one end (25a) cooperating and attaching to the corresponding tilting lever (10).
  • the first pulley (15) is arranged on this inner side endpiece, for allow the reception of the second transmission belt as indicated previously.
  • Said nozzle (25) has at its end a flange (25b) arranged with a projecting element (25c) forming a stop. Said collar (25b) by this stopper comes opposite the transverse face (8d) of the pressure roller (8) also fitted with a projecting shape (8e) constituting a stop. Said end piece (25) extends into the recess (8c) of the pressure roller by a cylindrical bearing surface (25d) which is capable of coming to bear and slight contact in the bottom of said obviously.
  • a return spring (26) is arranged on the cylindrical seat (8d) with a first end (26a) integral with the outer flange (25b) and a second end (26b) secured in the bottom of the recess.
  • said voltage said mechanism is arranged to have an effect multiplier.
  • This specific implementation is then illustrated in Figures 6 and 7. More specifically, said pressure roller is arranged at a end (28a) with a long shoulder span capable of receiving a ring (29) forming a sleeve whose end (29a) is likely to engage in a hook shape of the tilting (9) of the pressure roller.
  • the other end of the roller presser has a shoulder of great length (28b) capable of to receive the tensioning reduction mechanism.
  • the very long litter receives a first ring (30) or internally indented end piece forming a housing for the receiving a return spring (31).
  • This ring has a scope in projection (30a) on one of its lateral faces, facing the support zone of the material on the pressure roller.
  • This surface projection is likely to follow the peripheral contour of a flange (28c) formed on the part fixed the range of the pressure roller.
  • a fixed protrusion point or stop (28d) is arranged on said flange, also allowing the anchoring of a end of the return spring (31).
  • the other end of said return spring of the first ring is integral with the aforementioned long, fixed span.
  • a sheath (32) Adjacent to positioning of said first ring, a sheath (32) is provided with a collar (32a) passing through the first ring and against which comes also in support a second ring (33) capable of being put in rotation against a second elastic return means (34).
  • This second ring or end piece is arranged at the end of a support sleeve (35) which in turn has, in opposition, a pulley (35a) receiving the transmission belt (C2), associated with the device drum distributor.
  • This second ring has a stop projection (33a) and is set in motion during rotation of the drum against its elastic return means, one end of which is fixed to the bottom of the ring and the other end at a fixed point of projection (32b), formed on the collar (32a) of the sleeve (32).
  • This secondary projection point (32b) is advantageously offset angular with respect to the fixed point of projection (28d) of the first flange.
  • the angular differential is advantageously a few degrees between 5 ° and 10 ° for example. It can be different depending on the amplitude you want give to the tensioning mechanism.
  • Said secondary projection is mounted integral with the support of the first ring to then allow the training of this one in the conditions set out below.
  • This reduction mechanism can include two rings in the above example, but if necessary, depending on the nature of the material distributed, the pressure roller can be arranged with one or several complementary rings.
  • the device includes a front flap fixed front (27) which is snapped onto the lower part of the flanges (1b) of the housing, in appropriate openings (1b6)
  • a protective plate (28) is also positioned between the part front of the flanges (1b) of the device through an opening (1b7) appropriate. This protective plate extends to the back of the device to separate the receiving area of the drum and the second pulley from the material reel and pressure roller receiving area.
  • This plate (28) thus has projections (28a) on its rear edge (28b) which snaps into openings (1a2) arranged on one side and on the other side of the support (23) of the fourth pulley (22).
  • the plaque presents also on its longitudinal edge (28c) before projecting fingers (28d) which penetrate into openings (1b8) formed between the flanges.
  • This protective plate (28) has a notch (28e) for the passage of the third transmission belt.
  • the drum is arranged in any known manner with a device for retractable serrated cut, as described in the previous patents of applicant, and in particular in patent FR 2332215.
  • the dispensing device thus described according to the invention has many advantages.
  • Another advantage lies in the better guiding and holding of the strip of material on the drum to the cutting area.
  • the material strip is in effect maintained by the lower strand (20b) of the third belt according to a large angular distance during rotation of the drum before the exit of the cutting blade. There is therefore no possibility of shifting the strip of material.
  • the deflection roller can be placed at an adjustable distance from the drum to take account of particular characteristics of this drum. It can indeed be a drum with variable diameter depending on its ability to act as format selector.
  • the drum can be simple that is to say without function selective format but with a different diameter.
  • said pressure roller can incidentally provide another advantage when installing the new material reel. Account given its weight, the pressure roller due to its elastic mounting and tilting towards the rear of the device can constitute a counterweight for relieve the operator when placing the spool.
  • the material dispensing apparatus offers an operation very flexible and noiseless. Its construction is simple. It also allows a cut of wiping material of any kind.
  • the characteristics of the device in its application have been exposed to wiping hands by providing for the positioning of the mechanisms frontal and parallel situation with respect to the bottom face of the casing.
  • the dispensing device can be used also in its application of toilet paper distribution.
  • the different mechanisms are oriented in one position perpendicular to the bottom face of the housing.
  • Two flanges identical to those (1b) described are arranged parallel to the bottom face of the housing. It is simply added a complementary fixing wall for the positioning of the support (23) of the fourth pulley receiving the third transmission belt.
  • the shape of the drum can be arbitrary since there is no more support and contact with the loading reel or with the roller presser on the drum.
  • the installation of the cover tends by its contact with the protruding dishes flanges to ensure perfect maintenance of the mechanisms and components of the device. Removing or opening the cover allows the operator to grasp the protruding dishes by causing the elastic spacing of the flanges (1b) to allow reloading of a new reel of material.
