Definitions

  • the invention relates to a device for depositing a fleece or the like. According to the preamble of the main claim and a method according to the preamble of claim 12.
  • Such fleece tape layers are used, in particular, to lay down nonwovens, fibrous webs, spunbonded fabrics or the like supplied by a card or the like on an outfeed belt moved at a predetermined variable speed.
  • the nonwoven fabric fed by the card is transported on a feed belt driven at a predetermined speed.
  • the nonwoven fabric is usually at least partially transported between two conveyor belts that move at the same speed.
  • These conveyor belts are designed as endless conveyor belts. In order to deposit the fiber fleece as evenly as possible, such fleece belt layers require carriages in which deflection rollers for the conveyor belts are mounted.
  • the sudden change in speed of the wagons can cause an irregular warping of the nonwoven fabric, because of the time-dependent adjustment of the wagon and belt speeds due to the suspension of the frame and the working elements. With a sudden acceleration therefore the fleece cannot immediately follow the conveyor belts.
  • the nonwoven belt layer it is important to control the conveyor belts and carriages relative to one another in such a way that the most uniform possible storage is possible.
  • a nonwoven band layer is known in which the uppercarriage and the laying carriage have a common or separate drive which moves the carriages at different speeds in the opposite direction.
  • the uppercarriage always runs at half the speed of the laying carriage and covers half the distance of the laying carriage.
  • the drive is designed as a servo drive and connected to a freely programmable control. The speed of the cars can thus be changed as desired via their route, the acceleration phases in the reversal points of the travel movement being able to be influenced as desired.
  • the exit speed of the fleece always corresponds to the fleece inlet speed.
  • the invention is based on the object of designing a method for depositing nonwoven tapes or the like and a nonwoven tape layer in such a way that the nonwoven also has a delay (positive delay) at laying speeds below the belt infeed speed and also a compression (negative delay) at laying speeds above the belt infeed speed can be filed.
  • the laying carriage speed can be set to a higher or lower speed relative to the running-in speed of the fleece in order to compress or stretch the fleece when it is laid down. Intermediate values or non-uniform warping or upsetting over the laying width can also be set. In extreme cases, it is also possible to change the fleece exit speed on the laying carriage towards zero. It is important here that the fleece can be deposited with delay even at laying speeds below the strip inlet speed and also with compression at laying speeds above the strip inlet speed.
  • the invention advantageously makes it possible to work with a delay even in the reversal areas in which the laying speed of the laying carriage has to be reduced to zero up to the reversal point and from there must be accelerated again, with even a specific thinning of the fleece in the edge area is achievable, which is advantageous for subsequent processing processes.
  • the coupling of the uppercarriage, the laying carriage and the tensioning carriage via a single force transmission element in connection with two drives acting on the force transmission element advantageously makes it possible to control the movement of the uppercarriage and the laying carriage independently of one another.
  • warpage (or compression) for example of ⁇ 15%, can be set smoothly.
  • the two drives for the uppercarriage and laying carriage travel are controlled by a computer. It is possible to lay the pile without warping, compressed or stretched, depending on the specification, with speed differences between the belt speed and the laying carriage speed.
  • the tensioning carriage always keeps the main conveyor belt tensioned.
  • the tension carriage is brought into its respective position by the power transmission element and therefore does not require a separate drive.
  • a deflection roller arranged in front of and behind the laying carriage is driven for the main conveyor belt.
  • a delay can be set directly on the difference in the peripheral speeds on these deflection rollers.
  • Another exemplary embodiment consists of providing an electronically controlled linear drive for the superstructure and the laying carriage and coupling the uppercarriage, the laying carriage and the tensioning carriage to one another via a single power transmission element.
  • the tensioning carriage consists of two carriage parts arranged at a distance from one another, in each of which a deflection roller for one of the conveyor belts is mounted.
  • One or more intermediate carriages are arranged between the uppercarriage and the laying carriage. These intermediate cars have the The advantage of distributing the decelerations and accelerations over several machine elements.
  • the nonwoven belt layer 1 (FIG. 2) has a feed belt 2, via which a pile or nonwoven 4 or the like of a card arranged in front with a uniform one but variable speed of 1.5 m / s is supplied.
  • a discharge belt 6 is arranged transversely to the conveying direction of the feed belt 2 on deflecting rollers 8, on which is deposited transversely and in a zigzag to the delivery direction.
  • a discharge belt 6 running longitudinally, ie also in the same direction as the feed belt 2 can also be provided.
