- the apparatus according to the invention is suitable for the distribution and cutting of wiping materials of all suitable materials, cellulose wadding, crepe paper and the like, being intended mainly for wiping hands, in semi operation - Automatic or automatic, and has a common arrangement, at the level of the drum, of the blade device for cutting the strip of material treated, as well as in the particular path of the blade for cutting the paper.
- the dispensing device is illustrated in FIG. 1 and is referenced as a whole by (1). It includes restrictively six parts constituting all of the components and mechanisms necessary for its operation.
- the apparatus firstly comprises a casing (2), molded in plastic material, capable of receiving a reel (3) for supplying wiping materials, a drum (4) supporting the blade (5), as well that a means (6) ensuring, on the one hand, the supply of the paper strip to the drum, and on the other hand, the tensioning of the paper.
- the movements of displacement of the blade towards the drum, with a view to cutting the paper are obtained by a rack means (7), positioned fixedly on one of the wings (2.1) of the casing (2).
- a protective cover (8) protects the aforementioned mechanisms and the strip of paper on reel, intended to be distributed.
- the protective cover is positioned by a labeling on the casing and their junction makes it possible to define, in the lower part, a longitudinal slot for the passage of the paper.
- the six aforementioned means are integrated into each other by simple labeling, to the exclusion of any connecting means of the screw or other type.
- the casing (2) is made in one piece, made of plastic, and comprises a bottom plate (2.2) having lateral wings (2.1a - 2.1b) profiled to form, in their upper part, triangular projections (2.3) having opposite and directly formed end caps (2.4), cylindrical, allowing the assembly of the material reel (3).
- the latter comprises, in known manner, an inner cylinder or sleeve (3.1) capable of coming to engage at its ends on said free-mounting end pieces. Said wings have a slight flexibility to allow mounting of the coil.
- reinforcement ribs (2.5) formed between the end pieces and the bottom plate (2.2) of the casing, these ribs making it possible to maintain and maintain good positioning of the turns between them of the coil.
- the bottom plate has, in its upper part, a profiled hook (2.6) or equivalent means, intended to snap onto the cover, to ensure closure of the assembly, this being supplemented by any additional locking means if necessary.
- the bottom plate has a cutout (2.7) allowing, if necessary, access to the interior of the mechanisms.
- the lower part (2.1c) of the wings of the casing extends forwards over a wide depth, thus corresponding very substantially to the width of the device.
- These wings are arranged with a plurality of holes to allow, on the one hand the positioning of the drum associated with the cutting device, of centering studs, of the fixed-position rack means (7), and on the other hand of the means ( 6) supply of the strip of materials and tensioning thereof.
- said lower part of the wings of the casing has a cutting line (2.1 d) to give flexibility, on the one hand, to the mounting of the means (6) and above all to allow a slight deformation to accompany the tensioning movements. and press the paper onto the drum.
- the casing has, in addition, a horizontal wall capable of receiving directly formed a hoop (2.8) in the form of a swan neck disposed in the middle part of the apparatus facing the drum and authorizing the guiding of the drawn strip of paper.
- the guide arch (2.8) formed on the casing has at the end a yoke shape (2.8.1) which is capable of engaging around the median disc (6.3) formed on the means (6) for feeding the drum. .
- This arrangement makes it possible to control the position of the supply means (6) relative to the drum so that the respective discs are perfectly facing and in support of each other.
- the horizontal wall has, on the outside, a rounded longitudinal border (2.9), facilitating the guiding of the paper at its exit, and disposed opposite a similar rounded longitudinal border (8.1) formed on the cover in the lower part of the protective cover.
- the drum (4) is made as a single piece of plastic material and advantageously comprises a shaft (4.1) whose ends (4.2), forming a finger, engage in the openings made opposite the aforementioned wings of the casing.
- This drum comprises a small diameter shaft around which is disposed and regularly distributed a plurality of adjacent and parallel discs (4.3) identified successively from right to left by looking at the drawings by (4.3.1, 4.3.2, 4.3.3, 4.3 .4, 4.3.5, 4.3.6, 4.3.7).
- the discs (4.3.2, 4.3.3, 4.3.4, 4.3.5, 4.3.6) have the same configuration and have on their periphery a profiled notch (4.4), capable of constituting the housing of the cutting blade ( 5) as will be explained later.
- the disc (4.3.1) is full and advantageously has a notch on its periphery (4.3.1 a), and is capable of ensuring the drive in rotation of the drum under the action of the means (6) which will be described thereafter.
- the front end disc (4.3.1) further comprises a hole (4.3.1b) allowing the engagement and centering of one end of the axis of the blade (5).
- the rear end disc (4.3.7) comprises a hole (4.3.7a), near its periphery, allowing the positioning and centering of the other end of the blade.
- the rear end disc (4.3.7) is particular in that it comprises an inner peripheral flange, disposed opposite the adjacent intermediate disc (4.3.6), this flange (4.5) defining an interior recess or chamber (4.5.1) for the.
- This flange also has a cut section (4.5.2) in the same plane as the notches (4.4) used to house the blade to facilitate molding of the assembly, said cut section allowing, transversely, according to a given sector, access to the interior of the aforementioned room, under the conditions set out below.
- Said chamber allows the positioning of the rack means (7) which is established in the form of a crown (7.1) adjusting, with play, in said chamber.
- This crown has, on the outside, two studs or projections (7.1.1 - 7.1.2) for centering, preferably of different diameter, to engage in the openings formed for this purpose, on the inner wing opposite the casing, to ensure easy installation and control in position.
- the other face of the crown is shaped with a semi-circular boss (7.2) extending with a plurality of teeth (7.3) forming a rack.
- the first three teeth (7.3.a) are of constant profile while the other four following (7.3.b) are of progressive profile to subsequently cause the movements of the cutting blade.
- the last tooth of the rack has a greater height than the others to allow the escape of the cutting blade and good penetration into the paper strip. This last tooth also constitutes, as will be explained below, a non-return stop means when the cutting blade has escaped from the assembly.
- teeth (7.3) of the rack thus produced, to follow the periphery of the boss (7.2) for a new operating cycle, and represent itself towards the first tooth formed on the boss (7.2).
- This last tooth of greater height offers another advantage which is to break the paper by orienting the blade more deeply.
- the blade (5) is made of one-piece plastic material and comprises a support rod (5.1), the ends of which form a finger (5.2), engage on the end discs of the aforementioned drum.
- the teeth (5.3) of the cutting part forming the blade (5) are formed in one piece with the support rod. These teeth have a profile in successive triangulation, and have a conformation not smooth, but curved downward to facilitate the attack of the strip of material to be cut. As a result, their underside has a concavity, capable of forming a seat (5.4) and a support zone for the part of cut material, as it appears in the drawings.
- the teeth of the blade are smooth or sawtooth.
- the blade has at its end, which is capable of facing the rack means (7), a piece forming a heel (9) profiled.
- the latter has a rear part (9-.1) in triangulation, with a rounded joining angle (9.2) and two curvilinear edges (9.3 - 9.4) opening towards the widest part of said heel which is shaped with a plurality of teeth (9.5) forming a rack, said teeth being arranged in progressive separation with respect to the axis of the blade, the leading tooth (9.5.1) being of greater height to ensure engagement.
- This piece forming a heel is integral with the axis of the blade, but in an eccentric position, so as to cause the angular pivoting of the blade and of the part itself according to a limited position.
- This pivoting allows the teeth of the blade to be housed inside the cavities formed on the intermediate discs of the drum, in a maximum fold-back position, said blade being in a plane below the generatrix defined by the discs of the drum.
- the external overflow of the teeth of the blade is limited by the abutment of the teeth with respect to said notches.
- the rack formed on the heel associated with the blade is capable of cooperating with the fixed rack formed on the means (7) to cause, under given conditions, the displacement and the exit of the cutting blade.
- the first meshing teeth correspond to the phase of the greatest effort when the teeth of the blade penetrate the paper. After the paper has been penetrated, the cutting edge begins and the effort becomes less. The cutting speed is accelerated by pulling on the paper, and a greater reduction is obtained by the fact that the teeth are larger, which allows faster cutting.
- Said means is formed, during the production of the disc concerned, and is in the form of a flexible tongue, free at one end, this tongue forming a cam and coming by elastic relaxation in slight external overflow relative to the periphery of the disc .
- This tongue is located opposite the axis of rotation of the blade and intended to come to a stop on the stop (10) formed on the horizontal wall of the casing.
- the advantage of such a complementary non-return stop lies essentially in the case where, by appropriate manipulations of the manipulator, the paper would be torn before cutting.
- This means (6) comprises a shaft (6.1) having at each of its ends centering fingers (6.2) for snapping between the lateral wings of the casing of the device. On this shaft, is arranged a plurality of discs or washers (6.3), the assembly being a single piece of plastic.
- the number of discs or washers is twice the number of intermediate discs formed on the drum.
- a certain number of discs (6.3a) will come in support on the intermediate discs (4.3.2 - 4.3.3 - 4.3.4 - 4.3.5 - 4.3.6) formed on the drum, while the other intermediate discs (6.3. b) will be located in an intermediate plane between two discs (6.3.1) formed on the drum.
- the assembly will contribute to ensuring a tensioning of the paper.
- the tree (6.1) can be solid or otherwise lightened.
- the means (6) has, at one end which is opposite the rack device, a disc (6.4) of larger dimension, forming a handwheel.
- This disc (6.4) is capable of being positioned between the end disc of the drum and the wing opposite the casing.
- This flywheel disc advantageously has a notch on its periphery (6.4.1).
- the flywheel (6.4) has adjacent to its internal face, a notched cylindrical shoulder (6.4.2) of complementary diameter identical to those formed along the shaft (6.1) to bear on the first disc produced on the drum, in order to ensure, after manual intervention on the handwheel, the rotation of the drum.
- the handwheel, after labeling and mounting the protective cover (8) extends substantially beyond the latter to be pushed manually by the operator.
- the wall casing (2) has, on its horizontal wall, near the lateral wing, opposite the rack means, a profiled stop (10), with a curvilinear profile forming a ramp, against which will come in support the profiled heel (9), associated with the blade (5) and support for the teeth (9.3) of the rack.
- This stop (10) intervenes to cause, after the cutting operation and disengagement of the racks therebetween, the reintegration of the cutting blade into the notches, formed on the intermediate discs of the drum.
- said stop causes the blade to tilt according to the arrow (F2) in a direction opposite 0 to the direction of rotation of the drum by causing it to be stored in the aforementioned notches.
- This complementary disc (11) has the function of acting as a stop and guide, if for any reason, the blade is in an exit position, relative to its recesses in the housing on the drum. The rotation of the drum will cause the heel piece (9) to stop by one of its curvilinear parts, against the aforementioned disc (11).
- the boss (7.2) formed on the rack means (7) has an external offset (7.4) which constitutes a stop means 0 and blocking in the heel position (9) associated with the blade causing during the return of the blade blocking it in the aforementioned notches of the drum.
- the protective cover (8) has, in the lower part of its wings, openings allowing it to be snapped onto the wings of the support casing using the fingers or projections (12) for centering and positioning.
- Said casing is, moreover, shaped in its bottom part with a wall (8.2) capable of coming opposite the horizontal bottom wall of the casing, but leaving a space or slot to allow the paper to exit the device. .
- the front of the protective cover has a vertical slot (8.3)
- the bottom part of the protective cover has a plurality of parallel projections (8.4) formed as a single piece and obtained during the molding of the cover, 2 these projections being intended to come opposite the intermediate discs of the drum, penetrating substantially into the recesses (5.5) of the blade, during rotation of the drum, and thus in the bottom portions of the teeth of the cutting blade.
- the main purpose of these projections is to ensure better guidance of the material drawn.
- recesses (5.5) have been formed on the blade support rod to allow proper operation of the assembly. It is therefore necessary to describe the operation of the semi-automatic device, with particular reference to Figures 4 to 7 of the drawings.
- the device being loaded with a reel of material mounted on the end caps, on the lateral wings of the casing, the device is loaded beforehand.
- the operator presents the free end of the reel of material between the means (6) and the drum (4) and manipulates, for a few degrees, the handwheel so to cause the strip of material to be drawn between the drum and the means (6) and its exit from the rear of the device, without, however, opening and leaving the latter through the appropriate slot.
- the strip of material is kept in tension by the plurality of discs formed on the drum and on the means (6).
- the one-piece swan neck arch, formed on the housing ensures, as a complement, if necessary, the guiding of the paper.
- the operational cutting phase is as follows.
- the end of the paper strip is still located inside the machine in an area corresponding to the rear of the drum towards the swan neck part.
- the operator manually turns the handwheel, in the direction according to the arrow (F), which causes, by the rotation of the means (6), the rotational drive, in an opposite direction of the drum, in the direction of inside the housing.
- the blade is placed inside the notches, leaving a space of a few millimeters relative to the fictitious generator formed by the intermediate discs of the drum before opening.
- the progressive rotation will allow the presentation of the first respective teeth formed on the rack associated with the blade and the fixed rack of the means (7).
- the end of the strip of material comes out of the slot formed on the device, and can be grasped by the user. The latter then pulls causing the drum to rotate, thereby ensuring the continuity of the cutting operation.
- the blade by the teeth of the two racks, will be pivoted to exit and cut the strip of paper, as a result of the teeth of profile progressive.
- the teeth come out at the rear of the device and the strip of material will be torn gradually, the blade pivoting in the notch formed between the intermediate discs of the drum.
- the total output of the blade will correspond to the exhaust and meshing of the last two teeth with the racks, the last tooth formed on the fixed rack causing the maximum output of the blade.
- the reentry of the blade is then effected by the abutment and contact of the piece forming the heel of the blade with the curvilinear stop fixed on the bottom wall of the casing.
- This curvilinear part forming a ramp causes, by an opposite effect, the tilting and re-entry of the blade into the notches formed on the discs of the drum.
- the pivoting of the blade ipso facto causing that of the piece forming the heel, the latter is tilted without making contact with the fixed position disc of the means (7).
- the continuous rotation of the drum then brings said heel piece into contact with the abutment disc formed at the end of the means ( 6), which in turn causes the blade to be withdrawn and reinserted into its housing defined by the notches on the intermediate discs.
- the maintenance and blocking in position of the blade in the notches in the second phase of the operating cycle of the drum return corresponding to the intervention of the curvilinear stop (10), are obtained by blocking said blade to the using the additional shoulder formed on the boss (7.2) which causes the blade to be retained in the notches of the drum. Unlocking takes place when the heel (9) associated with the blade takes up a new position for presenting its teeth with those formed on the means (7).
- the semi-automatic device thus described, comprises a limited number of parts, six as indicated above, but each having multiple functions as it appeared in the description.
- the casing (2) is arranged with a hinged cover (8) whose inner face (8.1) is arranged with an overhanging projection (8.2) established in a perpendicular plane, said projection being disposed horizontally at a level such that it comes opposite the zone of engagement of the paper between the means (6) and the drum (4).
- the purpose of this projection is to guide and present the first strip of material to be distributed during loading, to facilitate its introduction between the pressing means (6) and the drum (4). Said projection therefore comes to be flush with the space formed, at the introduction of the paper between the means (6) and the drum (4).
- This arrangement is particularly practical and does not generate any additional manufacturing costs when the cover is produced.
- the prior exit from the strip of wiping material must be able to be carried out, in an easy manner, over a few centimeters, this in the case where the user cannot handle by the hand the handwheel.
- the handwheel (6.4) of the aforementioned type projecting from the outside of the cover has a cross shape (6.5) or any other polygonal section having an alternation of cavities (6.6) with protruding shapes. These cavities are such that they allow the positioning of the forearm of the user who can, then, by a lowering movement, cause the rotation of the steering wheel and therefore of the associated drum, ensuring the exit of the strip of material, for later grabbing by hands by the user.
- the engagement of the drum with the means (6) is effected by two serrated discs formed respectively at the ends of the drum (4) and of the means (6), as illustrated in FIG. 19.
- the two discs are arranged at one end of the body of the device, as described in the initial patent application.
- one (35) of the teeth is longer than the others to provide a counter-support zone.
- the cam ensures, by the fact of complete rotation of the drum, the lifting of the operating means.
- a device is used, referenced as a whole by (40) intended to allow the paper strip to be taken out of the device beforehand, with a view to gripping and pulling it by the user.
- This device is profiled, bent with two branches, formed as a single piece having a part forming a lever (41) projecting outside the device, to be manipulated by the operator, and extending by an arm (42) inside. of the device, to ensure the partial rotation of the drum, according to a determined sector to allow the exit over a few centimeters of the paper strip.
- Said arm (42) is located in a plane parallel to said lever, and is arranged at its end with a form in a serrated sector (42.1) capable of cooperating with a rack (44) disposed on the axis of the drum (4) receiving the cutting tool.
- a gap (45) allowing the passage of the corresponding side wall of the casing (8), the latter having , at the rear, a passage opening (46) of the bent part of the device.
- Said lever (41) has, in its rear part, a perpendicular extension forming an elbow (43.1), substantially horizontal, with itself a vertical extension (43.2) defining, by an appropriate shape, the articulation zone (43.3) of the device. More specifically, this articulation zone is arranged with two opposite centering studs (43.4) capable of engaging in openings formed on the one hand in the lower part of the side wall of the corresponding casing, and on the other hand, on an attached flange (47), disposed opposite, to form a fork shape allowing the articulation of the aforementioned device.
- the arm part is established from this articulation zone and extends forward in the same plane as the lever.
- the end of the arm thus has a serrated angular sector, with several teeth (42.3) of equal toothing, as well as with an end tooth (42.4) situated in the same plane as the above-mentioned ramp part.
- a rib (42.2) of great length disposed in a plane inclined with respect to the aforementioned serrated sector.
- This ribbing defines, on its front part, a ramp shape capable of cooperating, as will be described later, with a cam shape disposed on the axis of the drum.
- the angular position of the ribbing, relative to the teeth, is judiciously established to allow, after the exit for a few centimeters from the strip of paper, the lifting of the lever.
- the arm part In its thickness, the arm part has a lightening opening (42.5).
- the drum has, from its axis of rotation, overflowing, the aforementioned cam (48), as well as a rack (44) comprising several teeth.
- Said cam has a particular profile with a flattened "S" shape. This is defined with a first semi-circular half-part (48.1) against which the above-mentioned rack is positioned, and a second semi-elliptical part (48.2) arranged opposite.
- the junction of the two circular and elliptical half parts with respect to each other is established with a straight profile (48.3) on one side and a curved profile (48.4) forming a ramp on the other side.
- the shape of this cam thus defines a particular path which cooperates with the aforementioned rib (42.2), under the following operating conditions, with reference to FIGS. 21 to 26.
- the wiping roller apparatus being loaded, the device is in the rest position, that is to say that the lever (41) is in the horizontal position so that it can be manipulated by an operator.
- the wiping paper has not come out.
- the rack (44) mounted on the axis of the drum meshes with the first teeth of the serrated sector of the arm (42), while the profiled cam (48) in "S” is located in a plane oriented downwards, the shapes in "S” being substantially vertical.
- the ramp part (42.2) of the arm projecting at the end, forming a spout (42.6), is raised upwards in the position of maximum distance from the profile of the cam.
- the "S" shaped cam fixedly mounted on the drum has taken on a new orientation corresponding to the partial rotation of the drum, and is situated in a plane such that the rib part of the spout arm comes to bear on the part curvilinear (48.4) of the ramp.
- the teeth of the rack and the toothed sector formed on the arm are no longer engaged.
- the user has shown the traction of the strip of outgoing material.
- This traction will cause the complementary rotation of the drum, and therefore the overflow of the paper strip.
- the fixed cam (48) mounted on the axis of the drum will pivot according to the arrow (F2) and cause, due to its curvilinear profile, by constant support on the spout (42.6), the lifting of the device constituted by the arm (42) and the lever (41).
- the rack part (44) and the toothed sector of the arm are distant from each other, which thus allows, by a release, the easy lifting of the arm-lever assembly.
- FIG. 24 there is shown the position of the device comprising the arm and the lever in their respective position relative to the profiled cam and rack arranged on the axis of the drum.
- This representation corresponds to the moment of cutting of the paper strip by the cutting device introduced and positioned in the drum, as described above.
- the lever part (41) is raised to the maximum and the arm part (42) comes into contact with a stop (49) fixed on the side wall of the casing to limit its movement.
- the cam (48) profiled in "S” then has a position substantially horizontal, and the rectilinear part is also horizontal.
- the first teeth of the rack and the toothed sector of the arm are opposite each other ready to mesh.
- the lever At the end of traction and after cutting the paper strip, the lever returns to its initial position as illustrated in FIG. 2, the rack and the toothed sector being engaged. When passing into this rest position, the start of meshing of the teeth of the rack with the toothed sector of the arm is obtained.
- the implementation of this device is particularly advantageous in that it simplifies the assembly of the assembly.
- the operation of the device including the lever is easy to implement.
- the means (6) for feeding the strip of material to the drum (4), and which is illustrated in particular in FIGS. 27 and 32, making it possible to improve the distribution of the strip of material, whatever the directions of traction at the end of the strip by the user.
- the means (6) comprising a shaft (6.1) and a plurality of discs (6.3) intended to be in relation to the discs (4.3) formed on the drum, is established to offer a certain flexibility by deformation by report to said drum, and secondly by ensuring successive styling of the strip of material when it is in contact between the means (6) and the drum (4) during dispensing.
- the complementary discs (6.5) are provided on either side of discs (6.3) to have complementary discs (6.5) which have a diameter (D1) substantially greater than the diameter (D2) of the discs (6.3).
- D1 substantially greater than the diameter (D2) of the discs (6.3).
- the complementary discs (6.5) have a slight tendency to penetrate the material in the intervals formed between the successive discs of the drum creating styling ( Figure 27) or successive undulations resulting in better tensioning of the paper transversely to facilitate cutting.
- the complementary discs (6.5) have a smaller width than that of the discs (6.3).
- the discs (6.3) of the means (6) for feeding the paper strip of the material are produced with a decreasing diameter from the central central disc, at an angulation ⁇ identical on each side.
- This reduction in diameter of the various discs (6.3) is achieved by a tapering of a few tenths of a millimeter from the diameter of the consecutive discs.
- the means (6) which is snapped between the lateral wings of the casing can thus be substantially flexed during assembly, although the discs in relation to each other with the drum remain in contact.
- the drum (4) can itself, on its shaft between certain discs (4.3), be fitted with notches or weakening zones (4.6), preferably obtained by a reduction in diameter to allow it to offer a certain flexibility in combination with that obtained by the above-mentioned means (6). Thanks to these particular arrangements, a flexible mounting of the means (6) on the drum (4) and better paper tension for cutting.
- peripheral surfaces of the discs (4.3) can be fitted with gripping zones (4.7).
- the device can be arranged on some of the discs of the drum, and / or of the pressing means (6), rods damping in elastomer or equivalent allowing smooth operation of the apparatus.
