Definitions

  • such an operation splicing can be performed at a frequency which can be very variable and which depends on the length of material stored on a winding and the speed of production of a processing facility.
  • the operation of splicing is carried out by means of adhesive tapes placed on either side of the junction area.
  • the new roller is put in rotation with a tangential speed substantially equal to the speed of unwinding of the fabric when the butt joint is to be made.
  • a knife is used which is fixed beforehand the end of the material carried by the new roller and which, practically simultaneously with the joining operation, cuts the material of the roll exhausted so that it can then be evacuated.
  • the knife supports an adhesive tape allowing the junction between the two strips of material, the FR 2 130 876 describing an improvement to such a technology which allows apply a junction tape on the upper and possibly lower side an end-to-end junction made between two fabrics during the course of the process.
  • the method according to the invention makes it possible to carry out very compact installations, occupying a very small floor area.
  • the splicing is carried out so that the edges of the two ends of material are superimposed and arranged in the extension one of the other, which causes very great resistance at the junction area.
  • the invention therefore relates to a method of splicing between a strip material taken from a roller and feeding a processing line for said material and the start of a second roller intended for continue feeding after exhaustion of the first without stopping said line transformation.
  • This process meets the specifications of claim 1.
  • the operator can therefore ensure the preparation of the end of the replacement roller safely and in masked time, from simple way, since it suffices to position said end on the ramp suction of the press assembly, the joining operation being in turn performed automatically without the presence of the operator, without stopping production line which is supplied during this operational phase by the reserve of material provided downstream from the feeding station.
  • the invention also relates to an installation for setting up work of such a process.
  • This installation complies with Features of claim 2.
  • the feeding station is arranged, considering the position of the operator relative to the vertical frame at the rear of the joining assembly.
  • This feeding station includes means to automatically remove the empty roller and replace it with the new full roller.
  • the installation according to the invention has two joining assemblies as defined above, spaced from each other, and which define between them a work area for the operator, each vertical frame supporting the lower detour cylinder as well as a press comprising the support table movable between two positions, one horizontal for placing the end of the material carried by the new roller the other in contact with the transverse bearing surface of said joining sets.
  • the positioning of the material in a vertical plane passing through the lower detour cylinder and the bearing surface transverse is obtained by means of a movable assembly (carriage) upper part of the frame between the two work stations, said assembly comprising a detour element and the means for cutting the material taken from the roller in exhaustion route in order to be able to carry out the joining operation properly called.
  • the material supply can be obtained directly from rollers arranged on each side of the frames vertical, said rollers possibly being supported by carriages allowing their handling.
  • bearing surfaces can be flat, they can possibly be in the form of cylinders mounted free in rotation.
  • the operator can safely prepare the establishment of the primer of the material coming from the roll intended to be substituted for that in the process of exhaustion, the actual splicing operation being carried out automatically after the operator has left the area of job.
  • the invention therefore aims to solve the problem of carrying out splicing (connection) between the end of a feed roller (R1) of a line transformation of a material in the form of a strip (1) with the beginning of the material, also designated by the reference (1) of a new roller (R2), without stopping the material transformation line (1).
  • a splicing station designated by the general reference (2), essentially consisting of a vertical frame on the outside of which the material supply source (roller R1), the other side of which constitutes a operator workstation.
  • This frame supports two return cylinders (3,4), spaced from each other and which define a vertical passage for the material (1) in look at the work area.
  • the means of splicing mounted on said vertical frame, comprise means designated by the general reference (5) to stop the advance of the material (1) in the area vertical presentation between the cylinders (3,4) and, upstream of these means (5), a cutting assembly (6) intended to cut the material (1) originating of the roller (R1) being exhausted in order to carry out splicing.
  • the actual joining assembly is, in turn, constituted by a "Press" which, according to the invention, includes a table or ramp pivoting (7), able to take two positions, one horizontal such that shown in Figures 1 and 2 allowing the establishment and positioning of the end (8) of the material (1) coming from the new roller (B2), and the other, in look of a vertical support surface (9) arranged transversely to the strip of material (1), behind the latter, in the area between the first return cylinder (3) and the cutting means (6).
  • a Press which, according to the invention, includes a table or ramp pivoting (7), able to take two positions, one horizontal such that shown in Figures 1 and 2 allowing the establishment and positioning of the end (8) of the material (1) coming from the new roller (B2), and the other, in look of a vertical support surface (9) arranged transversely to the strip of material (1), behind the latter, in the area between the first return cylinder (3) and the cutting means (6).
  • the ramp or table (7) is advantageously a suction ramp which allows to maintain the end of the material (1) coming from the roller (R2). Possibly, the maintenance of the material could be ensured by other means equivalents, such as for example pinching.
  • the operator When this end is positioned, the operator relates to its surface a double-sided adhesive strip or a fusible strip.
  • this positioning of the material is produced by associating with the cylinder (4) a pressing assembly comprising a cylinder (10) capable of being rotated by a motor (11).
  • the material (1) is pinched against the cylinder (4) by means of a cylinder bringing the cylinder (10) into contact with the cylinder (4). Just do turn the cylinder (10) so that the cut end is positioned opposite the bearing surface (9).
  • the support surface (9) is associated with a heating pad.
  • the set (7,9) is subject to pressure, pressure communicated for example by any means suitable, such as a hydraulic flange acting over the entire support length.
  • these locking means can consist of two elements (13) in the form of stirrups which ensure the maintenance of the assembly (7.9) constituting the press.
  • the exhausted roller (R1) on which the material has been returned cut located below the knife (6) is evacuated and the new roller (R2) is positioned for normal feeding.
  • the operator can therefore bring a new roll and prepare a new one. connection phase.
  • Figure 2 illustrates in more detail the structure of a feed station of the material, equipped with a joining assembly according to the invention such that described previously and illustrated by figure 1.
  • the vertical frame supporting all of the means constituting the joining station is mounted on a main frame (20) which supports the material supply roller (R1).
  • the course of this roll is obtained by means of a motor (21). It could however be considered ensure the unrolling of the material by simple traction on the latter, the roller being then mounted free to rotate on a suitable support.
  • Such an operation is carried out for example by means of a swivel assembly (22) controlled by a jack (23) which transfers the exhausted tube to an evacuation zone carried for example by the carriage (24) which ensures the positioning of the new roller (R2).
  • this new roller (R2) is therefore brought by a operator by means of a carriage and, after joining operation, it is brought in drive position by the motor (21) by means of a lifting assembly (25) movable along the frame (20).
  • Figures 3 to 9 illustrate a second embodiment of a installation according to the invention, showing all the phases of the splicing on such an installation.
  • the installation according to the invention comprises two joining assemblies (A, B) arranged opposite one another and defining between them a work area for the operator.
  • the material supply (1) is obtained from two rollers (R1, R2) arranged on each side of the vertical frames supporting the means of splicing.
  • Such a design is particularly suitable when one is faced with joining operations close together, in particular in the case of heavy products, such as materials intended to produce articles molded or shaped which can weigh over one hundred grams per meter square, which therefore limits the length of the product stored in the form winding.
  • each vertical frame supports a cylinder detour (3) for the material and the press assembly consists on the one hand by a suction table (7) for positioning the end (8) of the material supported by the roller intended to be substituted for that in process exhaustion, and, on the other hand, a transverse bearing surface (9).
  • the positioning of the material in a vertical plane passing through the lower detour cylinder (3) and the bearing surface transverse (9), is obtained by means of a partially movable assembly high of the frame between the two workstations (A, B).
  • This carriage-shaped assembly (30) comprises a detour roller (31), and also supports the cutting means (6) of the material taken from the roller (R1) being exhausted in order to be able to carry out the splicing operation proper.
  • Such a cutting means is for example constituted by a pivoting knife, or by a cutter or any other equivalent cutting means.
  • the material that feeds the installation of transformation comes from the roller (R1), the carriage (30) being therefore located on the side left of the installation.
  • the operator prepares the primer (8) of the material (1) carried by the roller (R2) by positioning its end on the suction table (7) of the station (B).
  • the table is tipped over support (7) which bears against the transverse bearing surface (9), which allows the joining operation to be carried out.
  • a new roller (R1) can then be brought in ( Figure 6) and the operator can then proceed on the station (A) to the establishment of the end of the material of this roller for subsequent joining.
  • FIG. 9 illustrates a variant of an installation as described previously and illustrated by Figures 3 to 8.
  • the pivoting table (7) has, at its end, on its entire length, a cylinder (40) mounted free to rotate.
  • the transverse bearing surface (9) also consists of a idler cylinder mounted free in rotation and against which the cylinder (40) of the table.
  • the cutting means are constituted by a cutter, and this in a manner similar to the knife described and illustrated by figures 1 and 2.
  • such structure has the advantage of allowing the sticky element to be laminated and a restart of the line even before returning the swivel table to position horizontal to make a new preparation. This therefore results in a gain of time.
  • the table or pivoting ramp can be associated with means allowing its realignment of automatically with the end of the new material roll.
