Definitions

  • the invention relates to the technical field of simple winding or trancanning around spools of strips of material, for example rubbery, such as rubber used for the manufacture of a tire.
  • the term “gum” is understood to mean a rubber-based paste used in the manufacture of a tire.
  • This rubber-based paste can incorporate a reinforcing element, such as fabric, rope or cable, or any other component or structural element.
  • the invention finds an advantageous application in the continuous winding of strips around reels, from a web.
  • the device comprises means for cutting the strip when the first reel is full, so as to transfer and then attach a free end of the strip to the second reel.
  • the device is stopped and the strip is cut. An operator must then transfer and then manually reattach the free end of the strip to the second spool, disassemble the formed spool and replace it with a new empty spool. Then the device is restarted.
  • the loss of time is significant when it comes to changing the coil and restarting the winding around a new coil.
  • the current configuration also has other drawbacks, in particular related to the various handling of the coils, to the storage and conservation of the coils, to the loss of efficiency linked to the shutdown of the device, etc.
  • operator must perform several operations requiring the handling of heavy objects. Of course, it can replace only one coil at a time, which further increases the downtime in the event that several coils are formed and need to be replaced. The operator must handle the coils near other rotating coils, which presents a risk to work safety.
  • Requirement FR 2 969 133 A1 describes a device for winding a strip according to the preamble of claim 1.
  • One of the aims of the invention is therefore to provide a device making it possible to minimize the time for transferring the winding of a strip from a full reel, to a new empty reel, also to minimize the time. stopping the device, and automating the process of winding and transferring a strip to the new empty spool.
  • This object is achieved by the characteristics of a device for winding a strip according to claim 1.
  • the invention makes it possible to achieve a significant saving in time thanks to the two reels used alternately, to the arm tilting automatically from one reel to the other, and to the means for automatically attaching the strip to the empty reel.
  • a full reel is evacuated and replaced by an empty reel, in masked time during the winding of the strip on the other reel.
  • the operation of transferring the strip to the empty spool and reattaching it to the latter is performed automatically, without the intervention of an operator.
  • the process is remarkable in that after cutting, the free end of the strip is transferred to the second reel by an automatically controlled rocking arm.
  • the invention relates to a device (S) and a method for winding a strip (7), successively on a first reel (1) then on a second reel (2).
  • the latter comprises two coils (1, 2) for winding the strip (7).
  • Each coil is installed on a respective axis (13, 14).
  • the strip (7) is shown being wound around the first spool (1).
  • the direction of its rotation is represented by the arrow F1, the arrow F2 showing the direction of the rotation of the second coil (2).
  • the device also comprises an arm (4) mounted to pivot about a pivot axis between the coils (1, 2), and provided at its end with guide means (5) and means (20) for blocking the strip ( 7) for winding around the coils (1, 2).
  • the arm (4) is advantageously movable parallel to the pivot axis. Its mobility is achieved by mounting on a rail (17) allowing reciprocating back-and-forth movement along the coils (1,2).
  • a trancanning of the strip (7) that is to say to wind the strip (7) in an orderly manner around the coils (1, 2), turn by turn and layer by layer.
  • the guide means (5) and the locking means (20) are positioned at one end of the pivoting arm (4), opposite the pivot axis.
  • Said guide means (5) consist of two rollers (5a, 5b) between which the strip (7) runs, and having a spacing to allow the strip (7) to travel.
  • the rollers (5a, 5b) are spaced apart allowing the strip (7) to travel while being guided by said rollers (5a, 5b).
  • the device (S) advantageously comprises a control system (not shown) for detecting that the diameter of the wound strip (3) reaches a predefined threshold.
  • a control system for detecting that the diameter of the wound strip (3) reaches a predefined threshold.
  • other criteria can be used, such as for example the winding time. So the transfer from the strip (7) to the second spool (2) is started and its next phase is shown on the Figure 2 .
  • the arm (4) has rotated around its axis of rotation to move away from the reel (1) in order to prepare the operation for cutting the strip (7).
  • the arm (4) comprises a slide (6) movable radially relative to the pivot axis and movable along the arm (4), for example by a jack (16), to adopt a cutting position.
  • the slide (6) exceeds the guide means (5) and the locking means (20) along the arm (4) and offsets the strip (7) radially relative to the pivot axis.
  • the strip (7) is offset by means of a finger of a pair of fingers (6a) which the slide (6) presents, lifting the strip during sliding.
  • the two fingers (6a) have a variable spacing so that, after displacement of the strip (7), the two fingers are brought together to tighten the strip (7).
  • the strip (7) is held by the locking means (20) upstream of the rollers (5a, 5b) and by the fingers (6a) downstream of the rollers (5a, 5b).
  • the locking means (20) comprise two pneumatic or mechanical clamping fingers the spacing of which is reduced in order to clamp and lock the strip (7).
  • the arm (4) is then moved along the rail (17) to be placed in vis-à-vis the cutting means, constituted for example by scissors (8).
  • the scissors (8) can be mobile to cut the strip (7) offset.
  • the arm (4) moves away from the scissors (8), and further pivots around its axis of rotation to approach the second spool (2) and achieve the transfer.
  • the strip (7) is still held by the clamping fingers (20), and the slide (6) for its part returns to the rest position.
  • the winding of the first coil is continued for at least one turn to finish the winding and press the remaining end of the strip.
  • the pivot axis of the arm (4) is located between the coils (1, 2) so that the arm can pivot, according to a transfer operation of a free end of a strip, previously cut, from the first coil to the second coil.
  • the device (S) also comprises means for guiding the free end of the strip (7), consisting of a roller (10) rotated and installed on the end of a support (9).
  • the assembly is secured to a jack (15) allowing the roller (10) to approach or move away from the second coil (2).
  • the arm (4) and the support (9) approach the second spool (2).
  • the adjustable groove (18) constitutes means for automatically attaching the free end of the strip (7) to the second spool (2).
  • the roller (10) has a plurality of strands in the manner of a brush to facilitate guiding of the strip (7) in the groove (18).
  • the groove (18) has an adjustable width, thanks to a movable part (12) which is able to approach a fixed part (11) to tighten the free end of the strip (7).
  • the mobile part (12) and the fixed part (11) can be produced by two flanges.
  • the locking means (20) are moved apart to allow the movement and guidance of the strip (7).
  • the second coil (2) is then driven in rotation to start the winding operation, as shown in the figure. Figure 4 .
  • the arm (4) moves again along the rail (17) to face the second coil (2) and perform the simple winding operation or trancanning.
  • the first formed coil (1) can then be removed, manually or preferably by an automatic system, and in masked time when winding the strip (7) around the second coil (2).
  • the invention makes it possible to minimize the time for transferring the winding of a strip from a full reel, to a new empty reel, also to minimize the downtime of the device, and automate the winding process.
  • the invention makes it possible to implement a method for winding a strip that is simple, fast and secure.
