Definitions

  • the object of the invention relates to the technical sector of devices for distributing lengths of material wound on reels.
  • the invention applies to devices for dispensing paper, wadding and similar wiping materials.
  • the Applicant has created and developed various distributing and cutting devices which are widely used.
  • These devices are not limited to the type according to which the roll of material in service is mounted to rotate freely on a support, by being applied under pressure directly to a drum with non-slip surface, so that by simple manual traction on the strip of material overflowing under the device, a strip is distributed and automatically cut, the length of which is substantially equal to the circumference of the drum.
  • This cutting is carried out by a serrated cutting device associated with the drum and protruding from the drum when it is rotated by traction on the material, so as to penetrate the material thus stretched on either side of the cutting device.
  • the launched drum After cutting, the launched drum returns to its initial position through the action of different complementary members and a new strip of material overflows from the device.
  • a device has been described in particular in French Patent 2,332,215 and its Certificate of Addition 2,340,887. Improvements have been described in European Patent 157,713 and in French Patent Applications 85.19447, 85.02873, 86.18497, 87.14068 in the name of the Applicant.
  • this type of device mainly comprises, from a casing (not shown), a base plate (A) for wall mounting with wings (A1 - A2) receiving a drum (B ) in which is articulated at the side walls, a cutting blade holder (C) which is connected to means external to the drum to be controlled for cutting during the rotation of the latter.
  • a roller (F) of wiping material is mounted on a support bracket (G) articulated on the base plate and held resiliently in contact with the drum, the periphery of which is arranged to prevent slipping during traction on the overflowing strip. (F1).
  • the drum (B) is rotated and the cutting blade holder (C) associated with the control means, describes a curved path which makes it pass from a retracted position in the drum to an exit position (by a radial slot (B1) of the drum) where the serrated blade which is inclined in two orthogonal directions, can gradually penetrate into the material stretched on both sides 'other and thus detach a strip of length corresponding to the diameter and the circumference of the drum that by the combined action of penetration and rotation.
  • the drum which is connected on one side to an eccentric and spring lever mechanism, must return to the initial or armed position with a new strip of material overflowing under the ready device to be drawn, and with no possibility of going back.
  • a part (J) called a parachute is freely articulated around a bearing secured to a wing of the base plate.
  • This parachute carries at its upper part and opposite the drum, a pawl (L) articulated elastically at (L1) to be constantly applied at its free end to a stop (J1) of the parachute.
  • the wall of the drum carries, near its periphery, a projection (B2) which is positioned and profiled to pass above the stop (J1) and raise the pawl (L) when, after cutting the material, the drum is launched by the eccentric lever. As soon as the projection (B2) has escaped the pawl, the latter falls back into abutment on the stop (J1).
  • provision has been made to keep this movable stopper in the high position, despite its natural tendency to fall back when the drum approaches the zone where it must stop. so that said stop is pressed against the stop (J1) of the parachute which then oscillates against a spring (N) before returning by a projection (J2) in abutment against a stopper (A3) of the 'wing (A2).
  • a ramp (J3) judiciously oriented, dimensioned and associated with the parachute to force the movable stop to go up, or a lever freely articulated inside the drum in a point substantially diametrically opposite the point of articulation of the movable stop and suitably sized to be naturally under said movable stop, thereby retaining it in the high position so that it ensures the stop of the drum, when the drum is at the end stroke, while said lever retracts automatically under the effect of the movable stop rising when it comes into contact with the stop (J1), thereby allowing the movable stop (M) to return by gravity to the low position for reset the device.
  • a ramp (J3) judiciously oriented, dimensioned and associated with the parachute to force the movable stop to go up
  • a lever freely articulated inside the drum in a point substantially diametrically opposite the point of articulation of the movable stop and suitably sized to be naturally under said movable stop, thereby retaining it in the high
  • This type of device gives users complete satisfaction, in particular by its simplicity of use and its reliability.
  • This device is essentially suitable for dispensing lengths of strips of predetermined cut materials which correspond very substantially to a tensile force on the strip of pulled paper causing the rotation of the drum on one revolution at each operating cycle.
  • the dimensions of the cut paper strips are therefore related to the diameter and the circumference of the corresponding drum.
  • the devices of the aforementioned type allow the distribution of paper lengths of approximately 33 cm.
  • the Applicant then focused on the study and the arrangement of the current cutting device inside the drum, without necessarily causing a variation in the diameter and the circumference of the drum of the device. as currently used.
  • the apparatus for distributing and simultaneously cutting rolled up strips of material of the type comprising a roll of material mounted for free rotation on a wall support, applied under pressure to a drum with a non-slip surface, said hollow drum internally receiving a serrated cutting device associated with the drum and cooperating with means external to the drum to protrude therefrom in an arc, when the drum is driven in rotation by traction on the material, penetrating in the latter which is stretched on either side of the cutting device, said drum, after launching, returning to the initial position by complementary members such as a parachute, ratchet, stop arranged on the drum and on the wall support, l being remarkable in that the drum is arranged with at least two slots, to receive and allow the movement of at least two devices s closely associated cutting and likely to be actuated successively to alternately allow the partial overflow of their associated cutting blade, each cutting device being associated with a guide roller capable of cooperating with a profiled cam mounted on the axis of the drum , and
  • Figure 1 is a side view of the material distribution and cutting apparatus according to the invention, seen from one side.
  • Figure 2 is a view of the apparatus according to Figure 1, seen from the other side.
  • Figure 3 is a sectional view of the drum arranged according to the invention.
  • FIG. 4 is a view with partial section of the drum according to the arrow F1 in FIG. 3.
  • FIG. 5 is a side view of the drum according to arrow F2 in FIG. 3.
  • FIGS 6 and 7 show the operation of the improved cutting device according to the invention.
  • the internally hollow drum (B) is arranged to receive two cutting devices (C1 and C2) closely associated with each other arranged in opposition inside the drum, and capable of being actuated. successively to alternately allow the partial overflow of their associated cutting blade.
  • Each cutting device comprises in known manner a blade holder (C) receiving a serrated blade (1), said blade holder having at its base a rod (2) or bar passing through the drum (B) being suitably guided, l 'one end of the articulation bar of the blade holders receives a guide roller (3) capable of cooperating with a profiled cam (4) mounted on the axis of the drum.
  • this fixed cam (4) is arranged with a specific profile adapted to allow the successive and continuous actuation of the two blade holders (C1 - C2), and in fact the production of two cuts. It should be considered beforehand that each roller associated with a blade holder is in continuous and regular contact with the cam, the two rollers being simply placed at different places of the cam, according to a continuous path, their position being established to correspond to the successive actuation of each blade and blade holder associated to penetrate successively drawn strips of paper.
  • This cam (4) thus has a profile comprising the following zones:
  • This first zone extends in its upper part with a flared shape forming a hollow (4.2), oriented internally in the cam capable of forming a hollow and forming a seat for the reception of the successive rollers (3).
  • the cutting blade gradually enters the paper strip.
  • This hollow shape (4.2) is then extended by a third zone having a broad curvilinear and flared profile (4.3) corresponding to the finish of the cut as it appears in the drawings, located opposite the zone (4.1).
  • the cam has a rectilinear profile (4.4) making it possible to join the aforementioned zones (4.3 and 4.1).
  • the insertion into the drum of the two aforementioned cutting devices thus makes it possible to generate, from the rotation of the drum on a single turn, the actuation of said cutting devices and thus the production of two sections of strips of material.
  • the drum thus comprises two diametrically opposite slots for the passage cutting blades and, on the other hand, and advantageously, it is arranged on their peripheral periphery two rough zones (5) constituted by pieces of EMERI canvas or the like, capable of being in contact with the distribution service roller strips of paper ensuring a perfect hold of it.
  • each of the half-parts of the drum has an involute corresponding to the length of the strip of cut material of reduced dimensions such as for example 23 cm.
  • Another characteristic of the invention resides in a complementary function provided by each of the cutting blades successively when the latter does not carry out the operation of slicing a length of strip of paper. More precisely, with reference to FIG. 6, it can be seen that the first cutting blade (C1) (arranged on the right while looking at the drawing) performs the operation of cutting a piece of strip (M1) of material, separating from the following length (M2) resting on the drum on the upper half-periphery of the drum. At this instant, the first roller (3.1) is located on the profiled part (4.3) of the cam and the blade (C1) has largely penetrated into the paper strip.
  • the other cutting blade (C2) is still substantially re-entrant in the drum and its associated roller (3.2) is located on the area (4.2) of the cam (4), when the first cutting is finished.
  • a complementary rotation of the drum thus brings about a deeper engagement of the first blade in the drawn strip of paper (M1), while the second blade (C2) then gradually penetrates into the consecutive strip of paper (M2).
  • the action of the first cutting blade (C1) nevertheless reveals, between the two parts of paper strip adjacent to the cutting location, one or two connection points resulting from the specific profile of the blade teeth, as described in a previous Applicant's Patent.
  • the action of the next blade (C2) in the consecutive strip of paper (M2) thus provides an additional function when the cam (3.2) is in the "hollow” part (4.2) of the cam, a function which is to ensuring a holding effect of the paper strip thereby causing the initial piece of strip (M1) to be tensioned and thereby causing it to be torn off.
  • doubling the cutting device does not only result in multiplying the strips of cut paper, but said blades successively provide, depending on the rotation of the drum, a complementary effect of retaining the strip of next paper, thus ensuring better quality of the cut.
  • Another advantage of such an embodiment also lies in a better balancing of the mass of the drum by a homogeneous distribution of the cutting devices.
  • the invention advantageously makes it possible, from the design of a drum of standardized dimensions, to distribute variable lengths of strip of paper. From a predetermined diameter and circumference of the drum corresponding to the cutting at one time of a strip of paper, it is possible, by doubling the cutting device under the conditions indicated above, to ensure a distribution of strip of paper of reduced length thus generating a substantial saving in the use and distribution of the strips of wiping material. The device then has greater autonomy.
  • the profile of the cam is thus judiciously determined to ensure with great reliability the successive interventions of the cutting blades of the two cutting devices.
  • the invention also makes it possible to eliminate the eccentric and spring lever as used previously and this thanks to the complementary function exerted by the second blade of the complementary cutting device.
  • the drum with three cutting devices arranged angularly at 120 ° each in the drum and cooperating with a cam path of the type from that described above or substantially arranged by providing a so-called “active” zone ensuring the penetration of two cutting blades at different locations in the drawn strips of paper, and a so-called “passive” zone where the third cutting blade does not exert no intervention in the paper strip.
