Definitions
- the present invention relates to a machine for fitting heat shrinkable plastic sleeves on objects, especially low lying objects section, from a continuous sheath wound flat.
- this type of sleeve fitting machine has a shaping mandrel over which the sheath passes to open, a means of driving the sheath using motorized rollers which cooperate with a part associated with the shaping mandrel for threading on an object the open end of the sheath, and a cutting means intervening between the shaping mandrel and the object for forming a sleeve associated with said object.
- the machines described in aforementioned documents use motorized pressure rollers cooperating with counter rollers carried by the mandrel conformator, the sheath running around the conforming mandrel being pinched between the motorized pressure rollers and the counter-rollers mounted mad on associated axes of the mandrel.
- Document JP-A-1.410.808 thus illustrates a floating mandrel type conformator having, in addition a crazy roller and counter roller arrangement, a window central at the level of which two motorized rollers pinch the walls of the sheath.
- support for floating mandrel remains secured by rollers and counter-rollers provided above on the conformator.
- document US-A-2,765,607 illustrates a mandrel floating which is in two parts connected by rods lateral, forming a central opening in which motorized drive rollers pinch the sheath walls.
- the floating mandrel support is then ensured by a support of a bead of the part flattened upper (forming introductory palette) on the two motorized rollers.
- the invention aims precisely to solve this problem, designing a sleeve fitting machine that is more efficient and does not have the disadvantages supra.
- the object of the invention is therefore to design a sleeve-shrinking machine for plastics on objects from a continuous sheath coiled flat, which is fully compatible with sheaths with small diameters, for example diameters between 5 and 20 mm, while supporting rates high, i.e. well in excess of two hundred sleeves installed per minute, with positional control optimal sleeves placed on objects.
- a plastic sleeve fitting machine heat shrinkable on objects from a sheath continuous wound flat, comprising a shaping mandrel on which the sheath passes to open, a means of training of the sheath using motorized rollers which cooperate with an associated part of the shaping mandrel to put on an object the open end of the sheath, and a cutting means intervening between the shaping mandrel and the object to form a sleeve associated with said object, the shaping mandrel being substantially horizontal and comprising two coaxial torpedoes connected between them by a wired central element, with a torpedo upstream having an upstream end forming a pallet introduction and a downstream end with a smooth double bevel, and a downstream torpedo having an upstream end at double smooth bevel and one downstream end with straight edge adjacent to the cutting means, each torpedo of said mandrel freely resting on an associated V-shaped support, and the means sheath drive
- the introduction palette of the upstream torpedo extends in a plane which is substantially perpendicular to the pinch plane of the continuous sheath between the two rollers.
- This allows a conformation of the sheath around the mandrel which gives said sheath a ace-shaped section of tile at the exit of a mandrel conformator whose downstream torpedo has a substantially section circular, this shape being favorable on the one hand for smooth transfer of the sheath onto an object cylindrical, and on the other hand for the organization of a clean cut without bending the sheath, downstream of the mandrel shaper.
- the upstream torpedo and / or the torpedo downstream has two substantially flat side facets perpendicular to the sheath pinch plane continues between the two rollers.
- These side facets planes reduce the lateral friction of the sheath on the torpedoes of the shaping sleeve, which is particularly favorable when said sheath carries a deposit of varnish or other on its internal wall.
- the aforementioned wire element is a flexible wire anchored at both ends in the torpedoes, one of the anchors being releasable so as to be able to adjust the length of said wire element between said torpedoes.
- This wire element will for example consist of a wire of steel about 1 mm in diameter.
- the smooth double bevels upstream and downstream torpedoes are formed of planar facets inclined arranged symmetrically with respect to a plane median passing through the wire element and tangent to both pinch rollers.
- the smooth double bevel of the upstream torpedo is formed by two inclined planar facets about 30 ° and the two pinch rollers pass tangentially on this double bevel, while the double smooth bevel of the downstream torpedo is formed of two facets more slightly inclined planes.
- the cutting means comprises a blade carried by a horizontal axis rotating arm, and said means is positioned so that his blade shaves the right edge of the end downstream of the downstream torpedo.
- the cutting blade has two straight cutting edges meeting at the level a leading edge, and the two cutting edges are substantially perpendicular, being arranged so that the leading edge contacts the top of the sheath at vicinity of a folding angle thereof resulting from the passage of said sheath on the introduction pallet or between the two pinch rollers.
- the cutting means thus arranged makes it possible to obtain a perfectly clean cut made progressively, without folding the sheath, in a very short time.
- the two pinch rollers are coated with an elastomer on their periphery, and are in contact with each other on either side of their throat device which is trapezoidal in shape and has two facets inclined symmetrically to their plane median, forming a V of approximately 60 ° opening, and the two pinch rollers are chamfered on their edges end.
- the two pinch rollers are mounted on a support frame which can pivot, preferably around a vertical axis, in order to allow a overall lateral clearance of the drive means. A such clearance then allows rapid intervention and easy for cleaning or changing operation sheath format.
- Figures 1 and 2 illustrate a machine 1 of fitting of shrink plastic sleeves on objects from a continuous sheath wound flat, arranged in accordance with the invention.
- This machine has an assembly frame 2 surmounted by a glass compartment 3 in which are arranged all the mechanical organs ensuring the supply of objects, as well as the horizontal transfer of a sheath continuous wound flat with progressive advance for the wrapping of each individual object and the cut of the sheath to form a section of sheath or sleeve.
- a control cabinet 4, supported by a swivel console 5 allows the operator to monitor the different parameters of the laying machine, and possibly modify certain settings of the operating cycle.
- Elongated objects 10 for example pens with draw, arrive by an inlet chute 6 to a double barrel 7 rotated by a motor 8, the double barrel with peripheral notches 9 adapted to support each elongated object at two points 10.
- the object received in two aligned notches 9 of the double barrel 7 then progresses due to the rotation of the double barrel, and arrives at a checkpoint 11 of presence of object (for example ensured by a sensor optical), then at a post 12 which is the post sheath and cutting advance fundamental to define a section of sheath or sleeve covering the object 10.
- the object 10 coated with its sleeve then continues its trajectory circular to reach the level of a lower guide 13 which prevents it from falling, until it reaches a outlet chute 14, arranged here at the axis of the double barrel 7, the object covered with its falling sleeve then on a conveyor 16 which moves horizontally as shown by arrow 200.
- the objects 10 coated with their sleeves which are deposited on the conveyor 16 then pass individually at a shrink tunnel 17 fitted with heating elements (not shown here), for example infrared elements, to shrink each sleeve on the associated object.
- the objects covered with their shrunk sleeve are collected in a bin 18.
- Figure 2 makes it easier to distinguish a sheath continuous 20, wound flat to form a reel of reserve 21 mounted on a fixed support 22, which is unwound of this coil passing over different rollers to arrive at a horizontal transfer station 12 from sheath.
- a sheath drive means 90 with two motorized rollers 25, 26, whose drive is provided by a belt 27 passing around the output shaft of a drive motor 28.
- the sheath is then pinched between the two rollers 25, 26 between two torpedoes constituting the horizontal shaping mandrel.
- Sheath arrives at transfer station 12, after being passed between two guide rollers 29 here with a vertical axis, in a still flattened position, the section of the sheath then extending in a substantially vertical plane.
- a cutting means 30, which will be described in more detail more far away, is arranged at the outlet of this transfer station 12, at in the vicinity of the double barrel 7, in order to cut the end of the sheath threaded on the object, to define a section of sheath or sleeve.
- the sheath drive means 90 and its two motorized rollers 25, 26 are in this case mounted on a frame carrier 23 arranged in the form of a secured turret to a fixed cross member 24, being able to pivot about an axis vertical 19.
- a pivoting mounting allows clearance lateral assembly of the drive means 90. This is very advantageous in practice, because an operator can intervene quickly and easily, thanks to the clear access to the components of the drive means, for an operation cleaning or maintenance, or change of sheath format. Once the operation has been carried out, the operator returns the moving part to its operating position, and the assembly returns directly to the position alignment with the object.
- This pivoting mounting allows, in more possibilities for quick interventions, an achievement very compact means of driving the machine deposit.
- the fitting has a shaping mandrel over which the sheath to open, a means of driving the sheath using motorized rollers which cooperate with a associated part of the shaping mandrel for threading on a object the open end of the sheath, and a cutting means intervening between the shaping mandrel and the barrel support for objects to form a sleeve associated with said object.
- the shaping mandrel 40 of the laying machine according to the invention is however arranged in a very particular as will now be described.
- the shaping mandrel 40 is indeed substantially horizontal (with reference to its axis 100) and has two torpedoes coaxial 41, 42 interconnected by an element wired central 43.
- upstream and downstream are used here by reference to the direction of travel of the sheath, which is shown schematically in Figures 3 and 4 by arrow 101.
- the wire element 43 which is for example constituted by a flexible steel wire about 1 mm in diameter, is anchored at its two ends 52, 53 in the torpedoes 41, 42.
- the end 52 is an end olive which allows an anchoring in abutment by natural wedging, while the end 53 is fixed by an anchor which is releasable.
- the downstream end 45 of the upstream torpedo 41 and the upstream end 46 of the downstream torpedo 42 are shaped to present a smooth double bevel.
- the double bevels noted 48 and 49 of the upstream 41 and downstream 42 torpedoes are formed of inclined plane facets arranged symmetrically relative to a median plane passing through the wire element 43 and tangent to the rollers 25, 26.
- the double smooth bevel 48 of the upstream torpedo is formed by two inclined plane facets, for example by an angle of around 30 °, and the two pinch rollers 25, 26 pass tangentially over this double smooth bevel.
- each torpedo 41, 42 of the shaping mandrel 40 freely rests on an associated V-shaped support 60, the two drive rollers 25, 26 being arranged between these two V-shaped supports.
- the section in Figure 7 and the detail of Figure 8 makes it easier to distinguish one of these supports 60, with its V-shaped facets denoted 60.1 for a perfect axial centering of torpedoes.
- the supports 60 are here supplemented by an upper stop 61 avoiding the torpedo raising 41.
- Figures 7 and 8 also show the presence, on torpedo 41, two flat side facets 58, substantially perpendicular to the pinch plane of the sheath continues between the two rollers 25, 26. These flat side facets 58 prevent support excessive lateral sheath, which is particularly interesting when the sheath is coated with a varnish special or other on its internal face.
- the sheath 20 passing over the insertion pallet 44 is flat, but it opens gradually as it passes on the main part of the upstream torpedo 41 whose section is substantially circular. Although it is not not shown in Figures 7 and 8, the sheath will have in practice a slight bending at the top and bottom of the sheath which results from its initial flattened shape.
- the two adjacent pinch rollers 25, 26 are symmetrically arranged on either side of the element 43 of the horizontal shaping mandrel 40, and each roller 25, 26 has a complementary peripheral groove 65, 66 from that of the other roller 26, 25 in order to form a passage 67 of horizontal axis for said wire element.
- the rollers of adjacent nips 25, 26 also pass in the vicinity smooth bevelled edges of the torpedoes 41, 42, that is to say inclined plane facets 48 of the upstream torpedo 41 and 49 of the downstream torpedo 42.
- rollers 25, 26 The arrangement of the rollers 25, 26 is shown in more detail in Figure 10.
- the rollers 25, 26 are in contact with each other on either side of their peripheral groove 65, 66.
- the two pinch rollers 25, 26 will be coated with an elastomer on their periphery, for example hardness polyurethane adequate.
- the peripheral groove 65, 66 of at least one of the two pinch rollers 25, 26 can be trapezoidal as it is illustrated in Figure 10 (we can of course variant provide a different shape, especially a shape in traditional V).
- These two grooves 65, 66 then have two inclined facets 68, 69, the inclination being symmetrical with respect to the median plane denoted P of the two rollers 25, 26, forming a V of approximately 60 ° opening.
- These facets 68, 69 participate in the overall guidance, and avoid any lateral shift of the traveling sheath which goes on the wire element 43.
- the wired element 43 remains positioned in the median plane P, thanks to the positioning correct torpedoes upstream 41 and downstream 42 forming the horizontal shaping mandrel 40.
- the ace of diamonds form for the section of the sheath 20 is interesting since the quadrilateral thus formed just passes over the section of the object 10 to be coated by sliding lightly on this object. This is favorable for obtaining an axial positioning and very precise transverse of the sleeve on the object. Moreover, when the object covered with its sleeve arrives in the tunnel of withdrawal, the call for withdrawal is limited, in the measurement where the sheath tangents the object to be coated at four lateral zones, the retraction call concerning mainly the four slightly marked edges.
- the circular shape of the outlet section of the downstream torpedo 42 is naturally only an example, and we can provide other specific forms (in square, diamond or ellipse) depending on the shape of the object concerned, in order to make a sheath preform at the output of the conformator which is perfectly adapted to the section of the object. This facilitates precise placement, and allows high installation rates that can exceed two hundred sleeves installed per minute.
- FIG 3 there is also shown a cutting means 30, consisting of a blade 31 mounted on a arm 32 which rotates around a horizontal axis 32 ', in being driven by an associated motor 33.
- the plan noted 50 of passage of the rotating blade 31 will in practice directly adjacent to the right edge 51 of the downstream torpedo 42, which contributes to the development of a precise cut without folding the sheath during this cutting phase.
- the sheath continuous 20 exceeds the right edge 51 of the downstream torpedo 42, to thread onto the object 10 to be coated, and this over a predetermined length in advance (which can even go to the total length of the object).
- the drive of motorized rollers 25, 26 is stopped, and the cutting takes place, at the level of the section 50.
- FIG. 14 makes it possible to clearly distinguish item 10 received in a double notch 9 barrel 7, with the sheath 20 in the shape of an ace of diamonds which covers it.
- the section of sheath thus separated forms a sleeve 80 which is intended to be then retracted on the object 10 at the level of the retraction tunnel 17 of the laying machine.
- the two cutting edges 31.1, 31.2 are preferably substantially perpendicular, and arranged so that the leading edge 31.3 contacts a top of the sheath 20 in the vicinity of an angle folding thereof resulting from the passage of said sheath on the insertion pallet 44 or between the two rollers pinch 25, 26.
- an arrangement has been illustrated. of the two cutting edges 31.1, 31.2, with an attack at the upper folding angle 20 'of the sheath 20, but it stands to reason that one could foresee an attack at another folding angle.
- This arrangement of the edges of cutting edge of the blade 31, allows make an extremely satisfactory cut of the sheath 20 thanks to the blunt effect of the percussion exerted at level of the bending angle 20 ', followed immediately by a section of the upper left edge of the sheath made by the edge 31.1 of the blade, with simultaneously the attack progressive from the upper right edge then from the lower edge straight through the cutting edge 31.2.
