Definitions

  • the invention relates to a device for opening postal envelopes each consisting of a body and a flap connected by a fold, the flap being folded against the body when the envelope is to be opened.
  • This type of device is generally incorporated in a mail processing machine, realizing: loading, then closing, then franking of envelopes. It must open envelopes at a high rate, adapted to that of loading. Its operation must be very reliable, even in the presence of envelopes with small defects such as accidental sticking points between the flap and the body of an envelope, to avoid jamming requiring the machine to stop and intervention of an operator.
  • This device has several drawbacks.
  • the movement of each envelope is discontinuous since it arrives horizontally and departs vertically.
  • the operation of the rollers is itself discontinuous.
  • One of them is mounted on a pivoting arm having a rest position in which the rollers are spaced to allow the arrival of an envelope; and a working position, in which the rollers are clamped and rotate to drive the envelope.
  • this known device is sensitive to the presence of accidental bonding points between the flap and the body of an envelope.
  • the scraper is inserted between the flap and the body of the envelope, there is a risk of tearing the flap, and therefore of jamming.
  • This device needs to be adjusted for each type of casing, because the position of the casing relative to the scraper must be such that the scraper fits securely under the flap, and such that the rollers can tighten the envelope without tightening the flap. If the envelope is smaller, the two rollers may no longer be able to extract it from the chute. If the envelope is larger, the end of the flap may protrude beyond the end of the scraper. In this case, the scraper can never be inserted between the flap and the body of the envelope. The position of the end of the scraper must also be adjusted according to the thickness of the envelopes to be opened. The proper functioning of this known device therefore requires precise adjustments, depending on the dimensions of the envelopes and their flaps.
  • the object of the invention is to propose a device which does not have the drawbacks of this known device.
  • the device thus characterized has a particularly low probability of stuffing because the point of contact of the edge of the flap with the cone moves both on the cone and on the edge of the flap as the envelope is drawn into the device. The contact point moves towards the base of the cone and towards the tip of the flap. As this movement progresses, the flap is separated from the body by the cone. There is no collision.
  • the cone being in contact with the body of the envelope according to one of its generatrices, and being free in rotation, it rolls on this surface, since the envelope moves under the action of the roller d 'training.
  • This rolling movement has the effect of reducing the resistance encountered by the body of the envelope in contact with the cone.
  • the rotation of the cone facilitates the insertion of the cone into the space between the body and the flap, because it increases the relative speed of the surface of the cone relative to the flap, on the contact points of the cone and of the flap. This increase in relative speed reduces the sliding friction of the cone on the surface of the flap, and facilitates the breaking of the accidental bonding points, which clearly reduces the risks of jamming.
  • the axis of rotation of the cone is inclined relative to a plane orthogonal to the plane of the envelope when it is introduced into the device, so that the cone fits into the space created between the flap and the body by presenting its base more than its top.
  • the device thus characterized makes it possible to further reduce the risks of jamming.
  • the radius of curvature of the cone at the point of contact with the flap is increased by the inclination.
  • the displacement of the cone relative to the envelope creates forces directed towards the fold and does not create forces directed in the direction opposite to the fold. So it creates forces that tend to open the flap but do not tend to tear the flap at the fold.
  • the means for spreading further comprise a movable support, provided with a spring, for supporting the cone by applying to it a force directed towards the drive roller, so that during the interval between two openings envelope the cone is brought into contact with the drive roller and is rotated by friction on this roller.
  • the drive roller has, in the area where it is in contact with the cone, a section made of a wear-resistant material.
  • the device thus characterized rotates the cone, during the interval between two envelope openings, which allows the cone to already have a rotational movement when it comes into contact with the body and the flap of an envelope .
  • the cone thus has a greater speed of rotation than if it were provided only by friction on the body of the envelope.
  • An increase in the relative speed of the cone relative to the flap reduces the frictional force on the contact points of the cone and the flap and, therefore, further reduces the risk of jamming.
  • Figure 1 illustrates the arrival of an envelope to be opened and a first step of the opening consisting of arching the body 1 of the envelope, without arching the flap 2, to create a space 9 between the body 1 and the flap 2.
  • the envelope is brought into the device, in a direction represented by the arrow 13, by a transfer device not shown, comprising a chute 4 in the shape of a U.
  • the envelope slides in the chute 4 along the fold 8 connecting the flap 2 to the body 1.
  • the body 1 is inserted between a drive roller 11 and a counter roller 12.
  • the drive roller 11 is driven by a motor not shown, around an axis of rotation E which is parallel to the plane of the body 1 and orthogonal to the fold 8.
  • the drive roller 11 rolls on the side of the envelope where the flap 2 is not folded back.
  • the counter-roller 12 rolls on the side where the flap 2 is folded, without rolling on the latter. .
  • the drive roller 11 has a length such that it rolls over a major part of the surface of the envelope, but not on the region close to the fold 8.
  • the counter-roller 12 is located near the end of the roll 11 which is furthest from the region of the fold 8.
  • a crazy roller 5 is located opposite the drive roller 11, near its end closest to the fold 8, but the roller 11 is not long enough to be able to touch the roller 5.
  • the roller 5 has a edge which rolls on the flap 2 parallel to the fold 8 and near this fold 8.
  • the roller 5 has an axis of rotation G which is parallel to the axis of rotation E of the drive roller 11.
  • the diameter of the roller 5 is such that the edge enters the cylindrical volume defined by the straight lines generating the drive roller 11, so that an envelope passing between the drive roller 11 and the roller 5 is not pinched between them but is arched by the end of the roller 11 and by the roller 5 , around an axis approximately parallel to the fold 8.
  • the body 1 undergoes this bending because it is retained by the counter-roller 12.
  • the flap 2 is not retained by the counter-roller 12, it remains approximately flat , therefore a space 9 is created between the body and the flap 2.
  • the flap 2 therefore undergoes an opening beginning according to the arrow 3.
  • the counter-roller 12 is free to rotate about an axis F which is slightly inclined relative to the axis E of the roller 11, in the direction of movement of the casing, so that the counter-roller 12 exerts on the body 1 a force tending to bring it closer to the idler roller (5).
  • the edge of the roller 5 has two parts: a frusto-conical part 6 and a cylindrical part 7. The frusto-conical part 6 is closest to the roller 11.
  • This shape of the edge of the roller 5 allows an envelope to be put back in place under the action of the force exerted by the counter roller 12 in the direction of the roller 5, if the casing moves away from the bottom of the chute 4 and rises on the frustoconical part 6 of the roller 5 instead of remaining in contact with the cylindrical part 7 of its song.
  • FIG. 2 illustrates a second step in the operation of this same exemplary embodiment, by not representing all the parts for greater clarity.
  • the counter-roller 12 and the chute 4 are not shown.
  • FIG. 2 represents: a cone 20, intended to perfect the opening of the envelope; a first guide 31 in the form of an angle iron, and a second guide 30 in the form of a pin, intended to guide an envelope leaving the device, keeping it open at right angles.
  • the section of the cone 20 through a plane passing through its axis of symmetry C is a triangle having, at the top of the cone, an angle of approximately 30 °.
  • the cone 20 has a vertex 21 which is rounded and which is directed towards the fold 8.
  • the cone 20 is free to rotate about its axis of symmetry C. It is located opposite the drive roller 11, and rolls on the face of the body 1 of the envelope, where the flap 2 is folded back. It is in contact with the body 1 along one of the generatrices of this cone. The friction of the body 1 on the cone 20 causes the latter to rotate. On the other hand, as will appear below, the cone 20 is also rotated, in the same direction, by friction on the drive roller 11 during the interval between the openings of two successive envelopes.
  • the cone 20 enters the space 9 created between the flap 2 and the body 1 by the arching of the body 1 during the first operating step.
  • the cone 20 pushes back the flap 2 by rotating it around the fold 8, according to arrow 3.
  • the opening movement is very gradual because the point of contact of the cone 20 with the edge of the flap 2 moves along this edge .
  • the flap 2 always has a triangle or trapezoid shape, therefore the edge of the flap 2 has a linear shape inclined relative to the fold 8. Because of the inclination of this shape, the contact point moves to the surface of the cone 20 as it approaches its base, as the contact point approaches the top of the flap.
  • the diameter of the cone 20 increasing towards its base, the cone 20 therefore spreads more and more the edge of the flap 2 relative to the body 1, smoothly.
  • the axis of symmetry and rotation C makes an angle of about 17 °, with respect to an oxz plane orthogonal to the plane of the envelope when it is brought into the device, so that the cone 20 is inserted into the space 9 presenting its base more before its summit 21 , vis-à-vis the space 9.
  • the radius of curvature of the cone 20 at the point of contact with the flap 2 is greater, which reduces the pressure on these contact points and therefore reduces the risk of tearing.
  • the frictional force of the cone 20 on the flap 2 tends to move the latter in the direction of the roller 5, while, if the inclination of the cone 20 was reversed, that is to say if the cone 20 was inserted in the space 9 with the apex 21 in front, the friction of the cone 20 on the flap 2 would tend to move the flap 2 away from the roller 5 by pulling on the fold 8 and could therefore cause a tear in the flap 2 in some cases where the flap would resist opening due to incidental sticking points.
  • the axis C of symmetry and rotation of the cone 20 is inclined about 17 ° relative to a plane oyz coincident with the plane of the envelope when it is brought into the device. This inclination makes it possible to make the cone 20 tangent to the body 1 of the envelope according to one of the generatrices of the cone 20, in order to press the cone 20 as far as possible against the body 1. It therefore has the maximum chance of fitting into space 9 created by bending.
  • the end of the guides 31 and 30 is close to the cone 20, so that they take over from the cone 20 to keep the envelope open.
  • the guide 31 is formed by two walls constituting an angle, so that its concave part can match the convex part of a right angle formed by the body 1 and the flap 2 of the open envelope.
  • the guide 30 has the shape of a spindle consisting of a cylindrical rod terminated by a rounded conical tip 32, to penetrate into the space 9 following the cone 20 and maintain the opening obtained by the cone 20. This opening is close to 90 °, relative to the body 1.
  • the body 1 of the envelope slides between a wall of the guide 31 and the guide 30; while the flap 2 slides between the other wall of the guide 31, and the guide 30.
  • the guide 31 and the guide 30 guide the envelope in translation, while keeping it open, in a direction represented by the arrow 19 and which is orthogonal to the axis of rotation E of the drive roller 11.
  • this direction is in the extension of the guide direction of the chute 4 at the entrance to the device, this latter direction being represented by the arrow 13.
  • FIG. 3 represents a more detailed front view of this exemplary embodiment, with all the parts and an envelope which is about to be opened.
  • the envelope is brought in the direction of translation represented by the arrow 13, along the chute 4, by means of two drive rollers 50 and 51, driven by a motor not shown.
  • one of the sides of the chute 4, the side located closest to the drive roller 11, has an enlarged surface near the roller 11 to constitute a deflector 47.
  • This deflector 47 guides the face of the envelope, where the flap 2 is not folded, so that it is tangent to the surface of the roller 11.
  • the other flank ends in a sharp cut 48, a little before the roller 11 so as not to hinder the opening of the flap 2 of an envelope.
  • the drive roller 11 consists of three superimposed parts having the same diameter: a rubber part 26, because it is located opposite the counter-roller 12 and it must adhere to each envelope to train him; a part 27 made of a wear-resistant material, situated opposite the base of the cone 20, this base rubbing against the part 27 during the interval separating two envelope openings; and a part 28 of aluminum treated to be hard on the surface, this part 28 having only a role of guiding the envelope.
  • the end of the drive roller 11, on the side of the idler roller 5, has a flat face 33 secured to a drive shaft 29.
  • This flat face 33 is at a certain distance from the flat face of the roller 5 most close, which allows the body 1 and the flap of the envelope to pass between the roller 5 and the roller 11, without being tight, but by arching the body 1.
  • the counter-roller 12 is supported by an arm 44 pivoting around a fixed axis 43 which is a cylinder whose axis of symmetry is parallel to the axis E of the roller 11.
  • the arm 44 applies the counter-roller 12 in direction of the part 26 of the roller 11, under the action of a pin spring 42 having one end in abutment on a lug of the arm 44, and another end in abutment on a fixed arm 40.
  • the cone 20 is supported by an arm 45 also pivoting about the fixed axis 43.
  • the arm 45 applies the cone 20 in the direction of the part 27 of the drive roller 11, under the action of a pin spring 41 having one end in abutment on a lug of the arm 45, and another end abutment on the fixed arm 40.
  • the height of the arms 44 and 45, and associated springs 41 and 42, is such that these elements do not hinder the passage of the tip of the flap 2 during the opening of the envelope.
  • This figure also shows the inclination, of approximately 17 °, of the axis C of the cone 20 relative to a plane orthogonal to the plane of the envelope, when it is brought into the device.
  • FIG. 4 represents a top view of this exemplary embodiment, with all of its parts, but without an envelope.
  • the arm 44 is separated so that the counter-roller 12 does not impede the visibility of the cone 20 and the roller 5.
  • the drive rollers 50 and 51 are arranged symmetrically with respect to the chute 4 located at the entrance to the device.
  • the guides 30 and 31 are located in the extension of the chute 4.
  • FIG. 4 shows the relative arrangement of the axes C, E, G respectively of the cone, of the drive roller 11, and of the idler roller 5. It appears that the axis C of the cone 20 and the axis G of the roller 5 are located on either side of a plane perpendicular to the plane of an envelope brought into the device, and passing through the axis E of the drive roller 11. During normal operation of the device, the arm 44 carrying the counter -roll 12 is brought towards the roller 11 by the spring 41. The axis F of the counter-roller 12 then occupies a position which is represented by the point F 'in FIG. 4, and which is located in the plane of the arm 44 .
  • this point F ' is located near the axis C of the cone 20, that is to say on the same side as the axis C with respect to a plane orthogonal to the plane of the envelope and passing through the axis E.
  • This arrangement of the axis of rotation G of the idler 5, and of the axis of rotation E of the drive roller 11 has the effect of slightly arching the body of an envelope around the axis E. This bending facilitates the creation of the space 9, shown in the previous figures, between the flap 2 and the body 1 of an envelope.
  • Figure 5 shows a side view of this embodiment, more detailed, with a section along the view direction VV.
  • the envelope is represented at the moment when the cone 20 enters the space 9 created between the body 1 and the flap 2 by the bending which the idler roller 5 collaborates with the drive roller 11.
  • the envelope is driven in the direction indicated by arrow 13, that is to say moving away from the observer.
  • This figure also shows the bending produced by the counter-roller 12, the drive roller 11 and the roller 5, bending which appears in particular on the top of the figure: part of the body 1 is not perpendicular to the plane of the figure because of this bending around the axis E of the roller 11.
  • the flap 2 has a triangular shape.
  • the edge of the flap 2 is in contact with the cone 20 at a contact point 52.
  • the point 52 moves both on the cone 20 and on the edge of the flap 2 as the envelope is driven in the device.
  • Point 52 moves towards the tip of the flap 2 and it moves towards the base of the cone 20.
  • the flap 2 is moved away from the body 1 by the cone 20 without it there is the slightest collision during this movement. There is therefore very little risk of tearing.
  • the region of the cone 20 located near the drive roller 11 includes a generator 49 which is tangent to the surface of the body 1.
  • the cone 20 shaves the surface of the body 1 and has all the chances of entering the space 9 between the flap 2 and the body 1.
