Definitions

  • the invention relates to a method for monitoring and / or regulating the fabric tension of fabric webs processed on a reel-nibbling machine, the napping machine having coating and / or counter-coating rollers on the jacket of the cylinder that act on the fabric with coating and / or counter-coating energy.
  • the invention relates to a reel-up machine for carrying out the method according to the invention with coating and / or counter-coating rollers mounted on the jacket of the reel, a feed roller at the goods inlet and a take-off roller at the goods outlet.
  • double-acting brushing machines are generally used, the brushing rollers arranged on the jacket of the reel as coating and counter-coating rollers with wire-cladding are trained.
  • the wires of the line rollers generally point in the direction in which the goods travel over the reel, and the wires of the counter-line rollers point in the opposite direction.
  • the goods are effectively roughened by an alternating arrangement of line and counter-roller, ie the fibers are lifted off the base of the fabric.
  • a relaxation of the goods occurs between a line and a counter-roller and tension of the goods between a counter-line and a line roller.
  • Optimal processing of goods on reel-to-reel machines therefore depends on the amount of line and counter-stroke energy as well as the overall tension on the reel. Even for trained and experienced specialists, it is difficult Always find the optimal processing parameters, especially if goods with different properties are to be processed one after the other.
  • the invention is therefore based on the object of specifying a method with which the monitoring and / or regulation of the fabric tension can be automated in order to optimize the processing. Furthermore, a reel-up machine is to be specified for carrying out this method, in which the goods are automatically kept in the optimum tension in each case and are supplied with optimal stroke and / or counter-stroke energy, but which is nevertheless simple in construction and therefore economical.
  • the method according to the invention is characterized in that for a specific product, a specific target voltage value at the goods inlet and at the goods outlet of the grooving machine, which ensures an optimal distribution of the goods tension on the drum, is set such that the goods tension is preferably measured continuously on the entry and exit sides during operation, checked and the voltage values are compared with each other, and that in the event of a deviation from the predetermined voltages, the respective deviating voltage is automatically reset to the predetermined target value.
  • the invention is thus based on the knowledge that only from the comparison of the two product tension states before and after the reel, clear statements can be made about all the individual parameters that are important for processing, so that the respective deviating tension is preferably automatically set to the desired value by an electronic process computer can be.
  • a reel-up machine for carrying out the method according to the invention is characterized in that a measuring device measuring the fabric tension is arranged at the goods inlet and at the goods outlet. These measuring devices are connected to an electronic process computer which compares the existing product tension conditions with one another and automatically sets the required compensation voltage on the basis of this comparison.
  • a reel-up machine consists of a reel 1, the casing of which is formed in a manner known per se from conventional-type roughening rollers, namely from coating rollers S and counter-coating rollers G.
  • the line rollers S and the counter-line rollers G apply a line and / or counter-line energy to a product 2 to be roughened, the course of which is shown by a chain line.
  • a driven feed roller 4 is arranged at the goods inlet 3 and a likewise driven take-off roller 6 is arranged at the goods outlet 5.
  • a measuring device measuring the tension of the goods is arranged according to the invention at the goods inlet 3 and at the goods outlet 5.
  • the main elements of these measuring devices are two dancer rollers 7, 8 which are arranged between the feed roller 4 and the drum 1 on the one hand and between the drum 1 and the take-off roller 6 on the other hand.
  • the dancer rollers 7, 8 are looped around by the goods 2.
  • the dancer rollers 7, 8 are movable in a direction perpendicular to their axes of rotation and in the direction of the loops of the web 2 they form, in particular by means of pivot levers 13, 14. Two lateral pivot levers are provided for each dancer roller 7, 8.
  • any change in the fabric tension is measured both at the goods inlet 3 and at the goods outlet 5 based on the position of the dancer rollers 7, 8, for which purpose each dancer roller 7, 8 is connected according to the invention to a linear actual value sensor 15, 16 that detects its position.
  • These actual value transmitters 15, 16 can be, for example, conventional immersion potentiometers or similar measuring devices which convert a linear change in position into electrical output signals.
  • the dancer rollers 7, 8 act against at least one pressure element 17, 18 that generates a preselectable preload. 2, two pressure elements 17 a, 17 b; 18 a, 18 b provided. In this way, a target product tension can be selected.
  • the pressure elements 17, 18 are preferably designed as pneumatic piston-cylinder units, the amount of the preload being adjustable in the range from 0 to 300 N.
  • the dancer rollers 7, 8 thus do not actively provide for a fabric tension, but act as passive measuring devices moved by the fabric by tension or relaxation.
  • a separate drive in particular in each case a variable-speed DC motor 21, 22, 23, 24, 25, is provided for driving the drum 1, the line rollers S, the counter-coating rollers G, the feed roller 4 and the take-off roller 6.
  • a separate drive in particular in each case a variable-speed DC motor 21, 22, 23, 24, 25, is provided for driving the drum 1, the line rollers S, the counter-coating rollers G, the feed roller 4 and the take-off roller 6.
  • the linear actual value transmitters 15, 16, the pressure elements 17, 18 and the motors 21 to 25 are connected to an electronic process computer 26.
  • An input device 27 is connected to the process computer 26 for inputting target values for adaptation to different materials.
  • the electronic process computer 26 receives from the linear actual value transmitters 15, 16 electrical actual value signals which are proportional to the product tension present in each case.
  • the computer 26 compares these values and uses them to calculate the voltage compensation required in each case, which is subsequently set by optimally adjusting the speed of all the individual drives.
  • Fig. 3 it is shown that the fabric tension at both the goods inlet 3 and the goods outlet 5 is too low, so that both dancer rollers 7, 8 due to the prestressed pressure elements 17, 18 have extended the goods loop.
  • the positions of the dancer rollers 7, 8 shown are passed on to the process computer by the linear actual value transmitters (not shown). This is programmed so that in this case it increases the speed of the take-off roller 6, whereby the goods as a whole are stretched.
  • Fig. 5 shows a state in which the coating energy is too high in relation to the counter-coating energy, since the goods 2 are transported too strongly by the drum 1, so that the goods are stretched at the goods inlet 3 by the high tension of the drum 1 and at the goods outlet 5 is relaxed.
  • the computer causes a reduction in the stroke energy, i.e. a speed reduction of the drive motor 22 of the line rollers S.
  • the invention is in no way limited to the exemplary embodiment shown. So it is entirely within the scope of the invention to measure the tension of the web with equivalent means, such as. B. with strain gauges, hydraulic or pneumatic pressure measurements or the like.
  • the dancer rollers 7, 8 can also be linear, ie without a pivot lever, be movably stored. It is also possible to dispense entirely with dancer rollers and to measure the fabric tension only by suitable means, for example pressure gauges, in the deflection rollers 11, 12.
  • suitable means for example pressure gauges, in the deflection rollers 11, 12.
  • the training with the dancer rollers 7, 8 has the advantage that a pretension can be adjusted to adapt to different materials to be processed.
