Definitions

  • the invention relates to the storage of a rubber strip around a product reel that is adapted to be continuously wound and unwound.
  • the invention relates to a device that effects winding processes, the device being part of an installation for the manufacture of tires.
  • rubber strips are intended to be stored by being wound around a product reel that is rotatably mounted relative to a frame of a rubber strip dispensing installation (or "dispensing installation"). Such an installation is used to deposit locally a semi-finished product such as rubber strips on a tire being assembled.
  • a rubber strip (or "product") that is wound in a winding process by a dispensing installation contains a conventional rubber mixture for the manufacture of tires.
  • a rubber from such a strip is generally uncured and therefore has a high level of adhesion. Therefore, when the strip is wrapped on itself in a product reel, it is difficult to unwind the strip without damaging it. Since uncured rubber is a relatively adhesive material, it is recommended to place the rubber strip on a weakly adhesive liner strip to facilitate its subsequent unwinding from the product reel. As the rubber strip is unwound from the product reel, so too is the liner strip.
  • the rubber strip dispensing installation prefferably includes a second reel (a winding reel) carried by the frame for winding the liner strip as the rubber strip is unwound.
  • a second reel a winding reel
  • the full product reel and the empty liner winding reel are first removed. Then a new empty product reel and a new full liner winding reel are placed on the installation.

  • the liner strip when the liner strip is wound onto a winding reel, the liner is wound in a spiral from the part of the liner with the smallest width to the part of the liner with the largest width.
  • the liner and the winding reel can be fitted with so-called "Velcro®” strips, assuring fixation by simple contact and allowing release by sufficient force and in the correct pulling direction. It is noted that the part of this "Velcro®" strip attached to the winding reel provides a clearly visible reference point for the operator to easily identify the starting point of winding on the winding reel.
  • Velcro® strips can also be used, these strips being disposed on one hand on an extension of the liner beyond a surface supporting a rubber strip, and on the other hand, on the back of the liner and back a distance of one turn, so that the "Velcro®” strips overlap at the end of the winding process. It is also possible to ensure that the liner is longer than one turn, so that the last turn of the winding protects the exposed surface of the rubber strip (see US patent 5,641,132).

  • the fixed and sliding deflection rollers 120,122 ensure the predetermined position required to convey the liner 400.
  • the winding process of the invention further includes a step of conveying the rigid support 402 toward the product reel 200.
  • This step includes a step of forming a loop 404' in the liner 400 that allows the rigid support to be released.
  • the product reel 200 and the winding reel 104 continue to rotate in opposite directions (see arrows R and S, respectively, in Figure 14).
  • the actuator V2 is activated to move the swing arm 108 from the retracted position to the application position and the head 110 pivots toward the attachment position.
  • the platform 124 remains near the lower end 126a of the path 126 so that the deflection rollers 120,122 manage the predetermined position of the liner 400 (the precise position of the platform 124 being adjustable according to the diameter of the product reel 200).
  • the liner 400 is well obtained from the winding reel 104.
  • the product reel 200 and the winding reel 104 continue to rotate until the loop 404' disappears.
  • the rigid support 402 is separated from the product reel 200, and the liner 400 is wound onto the product reel 200.
  • the conveyance of the rigid support 402 facilitates the feeding of the product reel 200 while the sliding deflection roller 122 retains the liner 400.
  • the winding process of the invention further includes a step of closing the product reel 200.
  • the product reel 200 and the winding reel 104 continue to rotate in opposite directions (see respective arrows T and U in Figure 15).
  • the head 110 pivots toward the attachment position so that the upper roller 110a conveys the rigid support 402 toward the product reel 200.
  • the rotation of the product reel 200 ensures the complete separation of the liner 400 from the rigid support 402.
  • the swing arm 108 maintains the head 110 in the attachment position so that the upper roller 110a engages the product reel 200, thus ensuring the closure of the rubber strip.
  • the product reel 200 is filled with product, and the swing arm 108 returns to the retracted position.
  • the device 100 is put on standby in order to resume the winding process again, realizing a reduction in the tire manufacturing cycle time.
  • the two embodiments of the device 100 manage well the predetermined position of the liner 400 in relation to the deflection rollers 120, 122 during the winding process. It is understood that the pre-determined position of the liner 400 in relation to the deflection rollers 120, 122 is maintained for the duration of an ongoing winding process.
  • the winding processes of the invention can be controlled by PLC control and can include pre programming of management information.
  • a process setting can be defined using the properties of the rubber strip 300 and the liner 400.
  • a process setting can be defined using the parameters of the product reel 200 and the winding reel 104.
  • a monitoring system could be set up for all embodiments of the installation 10. At least part of the monitoring system may be provided in a portable device such as a mobile network device (e.g., cell phone, laptop computer, network- attached portable device(s) (including “augmented reality” and/or “virtual reality” devices, network-attached portable clothing and/or any combination and/or equivalent)).
  • a mobile network device e.g., cell phone, laptop computer, network- attached portable device(s) (including “augmented reality” and/or “virtual reality” devices, network-attached portable clothing and/or any combination and/or equivalent)).
  • the device 100 and/or the installation 10 may receive voice commands or other audio data representing, for example, the current state of a process in progress compared to the planned state.
  • the response may be generated in audible, visual, tactile (e.g., using a haptic interface) and/or virtual and/or augmented form.
  • a winding process may include a step of training the device 100 and/or the installation 10 (or training a system that incorporates the device and/or the installation) to recognize characteristics representative of the rubber strip 300 and the liner 400 (e.g., length and width and tensile strength values) and to make comparisons with expected values.
  • This step may include a step of training the device 100 and/or the installation 10 (or training a system that incorporates the device and/or the installation) to recognize non-equivalence between the values being compared.
  • Each training step includes a classification generated by self-learning means.
  • This classification may include, without limitation, the parameters of the materials used in the rubber strip 300 and the liner 400, the duration of the winding cycles and the values expected at the end of a current cycle (for example, the value of a quantity of the liner 400 recovered by the winding reel, etc.).
  • the terms “at least one” and “one or more” are used interchangeably. Ranges that are presented as “between a and b" include the values "a" and "b".
