Definitions

  • the present invention concerns a strapping system to be used in wrapping machines, and more particularly it concerns a system for the driving, tightening and welding of a tape or strap, on a product to be wrapped.
  • Such a strapping station essentially consists of a fixed bow, within which a strap is made to run to form a wrapper around the load, which is then tightened on the load and welded at the overlapping ends.
  • Strapping machines of this type have a relatively low operating frequency, due to the load stopping time, which is necessary for accomplishing the strapping.
  • step strappers have also already been suggested.
  • the strap wrapper extends on a plane longitudinally arranged to the load advancement direction and, rather, it is precisely the load which intercepts the strap and cooperates with the wrapping operation.
  • step strappers are well-suited for the wrapping of cardboard boxes.
  • cardboard boxes are piled in a certain number in their folded status and naturally tend to expand elastically, increasing pile volume. This natural expansion causes tensioning of the wrapping strap even in case it was not perfectly stretched upon application thereof.
  • the present invention hence aims at solving the problem of performing, in a particularly effective and controlled way, the step strapping of piles of folded cardboard boxes (or similar loads) while they advance along a conveyor. Moreover, it aims at improving the welding system of the strap edges, if they are made of plastic material, in any strapping machine and, in particular, in a step strapping machine.
  • the strapping system according to the present invention is applied along the path of a load conveyor (comprising for example also a series of motor-driven cylinders) of which, in the drawings, only a sliding plate T is shown.
  • This system essentially comprises three units, arranged below the plane of conveyor T and called main assembly 1, abutment assembly 2 and locking and welding assembly 3.
  • a strap supply assembly 4 is provided which, as will be shown in the following, is vertically mobile, from a home position above the plane of conveyor T to a work position below the same.
  • Main assembly 1 consists of a castle framework 11, whereon a pressure countercursor 12 is firstly mounted, by means of a pair of arms 13 forming an articulated parallelogramm, which allows a slight, springy vertical/horizontal translation movement thereof in opposition to elastic means (not shown).
  • Castle framework 11 is slidingly mounted on rail B and has a spur 11a, arranged at a lower level with respect to appendix 12, provided with a wedge-shaped edge, the usefulness whereof will be obvious further on.
  • Countercursor 12 extends backwards (with reference to the direction of advancement of a load, indicated by arrow F in fig. 2 ) with an elongated appendix 12a, ending with a bevelled wedge-shaped edge.
  • Stop notch 16 belongs to a small plate which ends at the front with a bevelled wedge-shaped edge 17a.
  • abutment bracket 17 With abutment bracket 17 there is associated a small unit, rotatable about a vertical axis 18b, which carries a knife 18 and a gripping arm 18a provided with a notch-shaped appendix 18c.
  • Abutment assembly 2 is instead mounted on a saddle 21, slidably mounted on a rail B.
  • Saddle 21 carries, on one side, in a lower position (i.e. at a height suitable for cooperating with notch 16) and more backwards with respect to direction F, a pressure roller arm 22 and, in a higher position (i.e. just below countercursor 12) and more forward, a thrust arm 23.
  • Locking and welding assembly 3 also consists of a saddle 31, slidably mounted on rail B, carrying a heated wedge-shaped element 34 mounted oscillating by means of a pair of arms 33 forming an articulated parallelogramm (in a way equivalent to countercursors 12 on assembly 11).
  • This welding member as it will be better highlighted also further on, has a shape and a way of operation disclosed in more general terms further on in the specification.
  • Strap supply assembly 4 essentially consists of a vertically slidable post 41, which carries a transmission pulley 42 of strap R coming from a supply bobbin (not shown).
  • the drawing does not even show the vertical moving system of post 41, since it is an arrangement fully within the reach of a person skilled in the field and which in any case is not part, per se, of the present invention.
  • figure 1 shows the strapping system in a home position, waiting for a load P (for example a pile of folded up cardboard boxes) arrives along conveyor plane T to be wrapped by wrapping strap R.
  • the initial end of strap R is, in this position, tightened between stopping notch 16 and pressure roller arm 22 of saddle 21.
  • Figures 2 and 2a show a load P which, moving along conveyor plane T in the direction of arrow F, meets strap R and drags it to the position shown, while it begins to wrap load P.
  • the load it is preferable for the load to be pushed onto plane T by a pusher device: this ensures that the load has overcome the positions established during strapping and, at the same time, makes very quick movements (as a matter of fact, the entire strapping cycle, must occur in an extremely short time, of the order of the second).
  • assemblies 1, 2 and 3 are still in the position of figs. 1, 1a ; one can see, however, that strap R, in addition to extending across load P, bends forward, enters slit T 1 of plate T and also adheres to assembly 1, and in particular to abutting plate 17.
  • Fig. 3 shows, on one side, that load P has advanced further and, on the other side, that arm 14 has performed a rotation (clockwise with respect to fig. 3a ) so as to bring the notch 14a thereof in contact with abutting plate 17, thereby tightening between the two another portion of strap R.
  • strap R is tightened and blocked also in a higher position than the initial tightening position (i.e. between 16 and 22).
  • FIGS. 4 and 4a show that load P has advanced further and at the same time saddle 2 has moved backwards, in the direction of arrow F', so as to release the lower end of strap R, following the mutual moving away of stopping notch 16 and pressure roller arm 22.
  • the strap end is now retained only between notch 14a and abutment 17.
  • FIGS 5 and 5a show that load P has advanced further, until it has overcome the vertical alignment with assembly 4 and released the window T2 of plate T.
  • the unwinding of strap R is preferably suitably clutch-operated, so as to impart a tension suitable for compressing the load: the pile of folded up cardboard boxes hence compresses elastically.
  • Figures 6 and 6a show that - the other parts remaining stationary - saddle 2 has again moved forward (arrow F) to perform two actions: on one side, the thrusting action of arm 23, which pushes the free end of strap R above stopping notch 16 and below appendix 12a and, on the other side, the gripping action by pressure roller arm 22, which grips strap R in a position below the plane of conveyor T and downstream of assembly 4 and begins to drag it towards stopping notch 16.
  • FIGS 7 and 7a show the completion of the function of saddle 2 which, coming even further forward (arrow F) has led strap R to wrap load P nearly entirely.
  • the two strap portions are now fastened, on one side, between abutment plate 17 and botch 14a and on the other side, between stopping notch 16 and pressure roller arm 22.
  • Figures 8 and 8a show a further step of the strapping process according to the invention, consisting in the cutting of the strap portion R which is still connected to the vertical translation assembly 4.
  • Arm 18a has been rotated counterclockwise (according to fig. 8a ) about pin 18b, to bring knife 18 to cut the strap and bring the notch-shaped appendix thereof 18c to grip the strap edge which is released by the cut and to tighten it against the rear side (with respect to direction F) of notch 14a.
  • notch 18c is arranged above the operation plane of blade 18, which cuts strap R in the proximity of the gripping point between arm 22 and notch 16.
  • strap R ends, also in the rear part thereof, with a free edge below the gripping point between notch 18c and notch 14a, as visible in fig. 9 .
  • Figures 9 and 9a show that the operation of cutting strap R has been performed, knife 18 being in an end-stop position ( fig. 9a ), while notch 18c keeps the tightening thereof against notch 14a. From fig. 9 it is evident also an initial step of forward movement of assembly 3, to bring wedge-shaped cursor 34 closer to the free rear edge of the strap.
  • cursor 34 is suitably heated (although a temperature of about 80°C is sufficient to cause the melting of the plastic material, it is preferable to overheat the cursor to about 280-300°C to ensure the necessary heat supply even at the high operation speeds required by the apparatus), each portion of plastic strap which comes in contact therewith is softened accordingly up to a weldable condition.
  • it hence embeds electric heating resistances, apt to increase the temperature thereof, at least at the time when the strap welding must be performed, to a melting temperature of the plastic material making up the strap being used.
  • the head end of cursor 34 is wedge-shaped, with an opposite and complementary inclination to the one of end 12a whereon the front edge of the strap lies.
  • the elastic suspension mounting of cursor 34 and of countercursor 12 cooperates to allow also a vertical pressure.
  • This joint effect of pressure and heating acts in an optimal way to soften the surface layer of the rear edge of the strap, for the purpose of a subsequent welding thereof to the front edge.
  • the upward thrust is obtained especially by the engagement of bevelled edge 16a with bevelled spur 11a, which translate the horizontal translation movement of assembly 1 into a vertical pressure.
  • Figures 12 and 12a show a step wherein saddle 3 with corresponding cursor 34 is brought backwards again (arrow F') into its initial home position, leaving free the space for the upward return of assembly 4.
  • Figures 13 and 13a show a further step, wherein assembly 4 is by now well above the plane of conveyor T and of the top of load P; at the same time arm 18a has returned backwards (clockwise rotation in fig. 13a ), into the position in which notch 18c moves away from notch 14a, so as to release the strap wrap in this position.
  • arm 14 is also caused to rotate in a counterclockwise direction, to remove notch 14c from the by now welded wrapper of strap R, so as to release load P and allow the continuation of the travel thereof along conveyor T.
  • Figures 14 and 15 show, in top plan and side elevation views, respectively, a diagram of the motorisation and motion transmission to the driving members of the strapping system, and precisely to assemblies 1, 2, 3 and 4 described above.
  • a motor 5 actuates, through a motion transmission comprising also a reducer 6, a shaft 7, whereon multiple cams 8 are keyed on.
  • Each of these cams in turn acts, through a follower lever 9, on a tie-rod 10; of course there are provided as many cams as the tie-rods are, i.e. the operating assemblies actuated by these tie-rods.
  • FIG. 15 shows diagrammatically a tie-rod 10b for controlling, the movements of abutment assembly 2 and a tie-rod 10c for controlling the movements of welding assembly 3, while the control tie-rod of main assembly 1 is not visible.
  • tie-rod 10d for controlling the oscillation of arm 14 with notch 14a
  • tie-rod 10e for controlling the oscillation of arm 18a with knife 18 and notch 18c.
  • the individual assemblies are rotatably mounted on suitable bearings/brass or slidingly on linear guiding rods/rails.
  • This motorisation has the advantage of great construction simplicity and at the same time of a great operation simplicity, since it is possible - through the design of the cam profile and of the keying angle thereof on shaft 7 - to obtain a perfect synchronisation, stable over time, of the different driven assemblies.
  • Reduction assembly 6 preferably comprises also a clutch to be able to determine at least two steps of variable slackness of shaft 7. In particular, it is necessary to determine a more or less pronounced slackness between one load and the other (depending on the distance between loads) and between the beginning and the end of the strapping step of each load (depending on the length thereof).
  • the operation steps of the clutch can be determined by the signal issued by a photocell detecting the passage of the front and rear sides of each load as it progresses on conveyor T.
  • Strap tape R coming from a bobbin (not shown), can be wound around load P in the way shown above, or in any known way.
  • Strap tape R comes from the lower part of the load and is made to run through a first gripping element 101 before running around load C. The end edge of the strap is then again guided horizontally, made to run through a second gripping member 102 and then halted against the remaining strap portion, in correspondence of point A.
  • the welding device provides that in the proximity of halting point A there is arranged a mobile pressure roller 103, which has the double function of accompanying the strap inside first gripping member 101, as well as pushing the strap during the welding work step.
  • pressure roller 103 is preferably rotatably mounted on a displacement body 103a, which is in turn slidably mounted on a rail 104 and actuated by a linear actuator 105.
  • displacement body 103a, or the same pressure roller 103 is mounted elastically pushed towards the load resting plane - i.e. it is pushed upwards, in the representation of the drawings - so as to be able to impart a significant elastic thrust against the strap during the welding step.
  • Rail 104 is aligned with the sliding plane of the strap, i.e. the plane whereon the strap wrapper is formed. Therefore, the displacements guided by rail 104 are parallel to the development plane of the strap tape.
  • displacement body 103a also has a sliding channel for strap R, which is substantially orthogonal to the displacement direction of body 103a.
  • the cooperating surfaces of guide G and of displacement body 103a are shaped as a cutting edge, so that a mutual displacement of these two members leads to cut off strap R.
  • a preferably wedge-shaped heating blade 106 is provided, also slidingly mounted on rail 104.
  • wedge-shaped blade 106 can translate on rail 104 through the action of an actuator 107 which acts on a blade-carrying slide 106a.
  • Blade 106 as already mentioned above, is floatingly mounted on blade-carrying slide 106a, i.e. partly free to oscillate elastically in an orthogonal direction to rail 104.
  • blade 106 - as diagrammatically shown in fig. 16 - is articulated with a parallelogramm system articulated to blade-carrying slide 106a, with the arrangement of elastic dampening members.
  • the front portion of wedge-shaped blade 106 is maintained at the desired welding temperature (for example between 280 and 300°C) and is intended to wedge in between the front flap of the strap (i.e. the free flap) and the tail portion of the strap lying on cylinder 103, in the proximity of the contact point with the front flap.
  • desired welding temperature for example between 280 and 300°C
  • heating blade 106 due to the mounting on rail 104, is itself apt to perform a displacement substantially aligned with the lying plane of the strap wrapper, i.e. parallel to the longitudinal axis of the front flap of the strap.
  • a plastic strap R removed from a respective bobbin, is introduced or launched in the direction of arrow V along the sliding channel found in fixed body G and in displacement body 103a.
  • the front flap of strap R follows the wrapper around load P, running on cylinder 103 and through the two gripping members 101 and 102, until it ends in A in contact with the tail portion of the strap.
  • the second gripping member 102 is raised to retain strap R.
  • the strap is then retrieved and tensioned, pulling the tail portion ( fig. 18 ), until tightening the strap wrapper around load P with the desired tension.
  • the first gripping member 101 is raised and blocks the strap immediately downstream of pressure roller 103 ( fig. 19 ).
  • displacement body 103a is made to progress ( fig. 20 ) by actuator 105, until it cuts the strap in correspondence of the sliding plane: between entrance 103a' and fixed body G.
  • the pressure roller simultaneously progresses, distancing itself from first gripper 101 and moving the tail of strap R closer to heating blade 106.
  • actuator 107 can cause heating blade 106 to progress towards pressure roller 103, bringing blade 106 from the home position shown in fig. 16 to the work position of fig. 20 .
  • pressure roller 103 In its feed movement, pressure roller 103 not only brings the tail strap in contact with the heating blade, but pushes said blade in the same direction. In actual fact, thanks to the specific mounting arrangement of blade 106 on slide 106a, cooperation with pressure roller 103 also leads to a lifting of blade 106, which hence comes in contact also with the overlying front portion of the strap.
  • the contact of the heating blade with the two strap portions causes the local softening or melting of the two opposite surfaces of the two front and tail flaps of strap R.
  • the heating blade progressively moves backwards along the same longitudinal axis of the strap tape, softening a long portion - which can be defined as desired - of the two strap flaps.
  • pressure roller 103 simultaneously, immediately compresses the two strap flaps with one another, softened by the previous passing of heating blade 106.
  • the softening action is hence continuous along the longitudinal development of the strap and the pressure action immediately follows the heating action, without time for any local cooling.
  • the advancing of body 103a can end when a sufficiently long portion of the two strap flaps has been wielded. If one intends to cause the entire tail to adhere to the front flap, it is necessary for the advancing travel to be at least equal to the development of the strap path existing between point of contact A and the entrance of cutting edge 103a'.
  • a welding device and relative welding method is provided which is extremely efficient, because it allows to join two flaps of plastic strap along a significant length, which can be defined according to requirements. Therefore, even in case of use of polyester, it is possible to operate at temperatures of about 300°C - without producing noxious vapours - because the smaller adhesion of the joining surfaces is offset by the wide welding surface, so as to ensure in any case high mechanical resistance.
