Definitions

  • the invention relates to a method for the heat treatment of a textile web in a tensioning machine, according to the preamble of claim 1, and to a tensioning machine for the heat treatment of a textile web, according to the preamble of claim 14.
  • the material webs to be treated are grasped at their two longitudinal edges by suitable holding means (clips or needle bars) which are fastened to two tensioning or transport chains, so that the material webs are then heat-treated in the wide state and with continuous transport can be.
  • the two transport chains are guided in guide rails at a corresponding transverse distance from one another in the region of the longitudinal edges of the web.
  • the object of the invention is to develop a method and a device according to the generic terms of claims 1 and 14 in such a way that, in the sense of a continuously constant product quality, misorientations of the product web (in particular strong deflection movements of the product web in the direction of the one and / or other side) can be recognized and corrected as reliably as possible.
  • the material web is continuously electronically monitored for deflection on at least one side with the aid of light transmitters and light receivers. If a predetermined size of this deflection of the web is exceeded, a control intervention is then carried out in such a way that at least one bent web section is at least approximately returned to a middle web transport level, that is to say at least to a middle position that is safe for the respective heat treatment.
  • a middle web transport level that is to say at least to a middle position that is safe for the respective heat treatment.
  • the web is monitored for its deflection on both sides by the light beams emitted by the light transmitters being directed or sent essentially in the longitudinal direction through the tensioning machine, the light beams on one side of the web approximately in the transport direction and on the other web side opposite to the direction of transport of the web are sent through the tensioner.
  • the light transmitter and light receiver can be arranged outside the tensioning machine, which is particularly important in the case of high-temperature tensioning machine designs such as dryers and / or fixing machines;
  • An area can be used to send the light rays (in the form of light barriers or light curtains) be selected over the width of the web, in which chain guide rails for the transport chains or the like cannot penetrate, the monitoring of the web or web orientations according to the invention can thus remain unaffected in every phase; In this way, deflections to different sides of the web, i.e.
  • the light beams directed opposite each other in the longitudinal direction of the tensioning machine on both sides of the web also lead to the advantage that the light transmitter (s) on one side of the web does not also affect the light receiver (s) on the other side of the web.
  • two light barriers e.g. laser light barriers
  • the smallest possible treatment width or working width can generally be set (for example of about 600 mm) via spindles or similar devices.
  • the procedure is now further such that the light rays are each approximately diagonal with respect to the limited longitudinal center section and - in consideration of the web surface - the light rays on one side of the web align with the light rays on the other side of the Cross the material web (in the sense of intersecting diagonal beams).
  • the heat treatment of the material web is generally carried out by inflating tempered gases, preferably warm or hot air, by means of nozzles arranged above and below the material web or material web transport plane (as is known per se). It is now advantageous if the corrective control intervention for returning excessively bent web sections by changing the gas flow, in particular with regard to the amount of gas from the nozzles, takes place on at least one web side such that the web sides is transported contact-free to the upper and lower nozzles.
  • tempered gases preferably warm or hot air
  • the web may occasionally flutter for a short period of time without a corrective control intervention having to be brought about as a result. Only if the interruption of the light beams or light barriers lasts too long within a certain period of time must a corrective control intervention take place. Accordingly, it is expedient if this corrective control intervention is carried out only after a certain time delay has elapsed, which can preferably be set by means of appropriate timing elements or the like. In practice this can e.g. look so that it is observed via a timer whether in a certain time period, e.g. There has been an interruption of the respective light beam in the last three seconds, more than one second. If this is the case, a corrective control intervention can be carried out for the relevant web side.
  • various measures with regard to the corrective control intervention could be carried out in a tensioning machine (including, for example, corresponding readjustments of the web or working width). According to the invention, however, it is considered to be particularly advantageous if, in the case of a corrective control intervention, the amount of gas / air to be applied to one side of the web is increased and, in adaptation, the amount of gas / air to be applied to the opposite side of the web is reduced.
  • the gas or air quantities to be applied to both sides of the material web are each reduced in an adjustable manner. This can be the case, for example, in the case of strong fluttering of the material web, in which the material web comes into contact with the opposing nozzle surfaces, so that the view of the light rays is temporarily prevented on both the one side and the other side of the material web.
  • the method according to the invention can further be developed in such a way that an interruption of the light beam triggers at least one optical and / or acoustic display for excessive deflection of the web.
  • an interruption of the light beam as a signal for excessive deflection of the material web can also be fed to an electronic control device which controls the corrective control intervention.
  • a quality-assuring system can be created as a whole, which can, without the intervention of operators, ensure that contacts of the material web with the nozzle surfaces are largely excluded or immediately corrected if such contacts occur at all.
  • this tensioning machine can largely be an otherwise conventionally designed tensioning machine, it is simplified so much in the present drawing for the sake of simplicity that only that parts which are essential to explain the features essential to the invention - essentially only schematically - are indicated.
  • the tensioning machine 1 illustrated in the drawing is designed for heat treatment, in particular for drying and / or fixing, a textile fabric web 2, it being particularly suitable for carrying out the method according to the invention described above. During this heat treatment, the web 2 is continuously (continuously) transported through the tensioning machine 1 in the wide-stretched state.
  • the tensioning machine 1 contains in the usual way a machine housing 3, which can be divided in its longitudinal direction into several treatment zones and has a web inlet 4 at its one end and a web outlet 5 at its other end - each approximately in the form of a transverse slot.
  • the material web 2 is thus transported through the tensioning machine 1 in the longitudinal direction during the heat treatment in the direction of the arrows 6 (FIG. 1).
  • two tensioning or transport chains 7, 8, indicated only schematically, are provided in the usual way, which are equipped with tension clips or needle bars in such a way that the web 2 detects at its two longitudinal edges 2a and 2b and can be held.
  • Nozzle devices for example in the form of nozzle boxes 10, are provided on at least one side of the web transport plane 9 and at a suitable distance from the latter Inflating tempered gases, in particular warm air, arranged on the web side facing them.
  • such nozzle boxes are arranged on both sides of the web 2 or the web transport plane 9, with these nozzle boxes 10 including blowers 11 for generating air circulation and at least regulating flaps 12, 13 in order to warm air in a required, adjustable or to be able to supply a controllable amount.
  • the upper and lower nozzles or nozzle boxes 10 which belong together, for example in a treatment field of the tensioning machine 1, are each supplied with treatment air by a common blower 11.
  • the corrective control intervention for returning the material web is carried out by changing the gas quantity delivery of at least one blower, for example by changing the speed of the corresponding blower as a function of a material web contact on the corresponding nozzle boxes.
  • the speeds of both fans, i.e. for the upper and lower nozzles can be changed or adjusted in different sizes.
  • the electronic control device 20 is connected to the nozzle devices described above. According to the representation in Figure 2, this connection is between dash-dotted control lines between the control flaps 12 and 13 of the nozzle boxes 10 and the control device 20; An additional possibility of this control connection would also be that the drive device of the blower 11 is connected to the control device 20 with respect to a speed control.
  • control connection is such that, in the event of a corrective control intervention, the amount of air inflatable through the selected nozzles / nozzle boxes 10 onto at least one web side is changed such that the web 2 can be returned to the area of the web transport level 9.
  • the arrangement of the blower 11 preferably sets the upper air (amount of air to the upper nozzle box 10), that is, in order to be able to achieve the same amount of treatment air on the top and bottom of the web, the air supply must generally be provided Top be throttled a little. If more air should escape on the underside of the web than on the top, then the air supply to the top must be throttled a little more.
  • the first light transmitter 14 is located on one, upper side of the web transport plane 9, directly in front of the slit-shaped web run-in 4, while the cooperating first light transmitter 16 is located on the outside immediately in front of the slit-shaped web run-out 5; in contrast, the second light transmitter 15 is located outside the machine housing 3 directly in front of the web exit and the cooperating second light receiver is located directly in front of the web inlet 4.
  • the tensioning machine 1 can be set to different web widths and thus to different working widths, it is expedient to do this also in the arrangement of the transmitter-receiver pairs 14, 16 and 15 To consider 17.
  • One of these transmitter-receiver pairs is arranged on each side of the web transport plane in a relatively narrow longitudinal center section 21, the width b of which is limited by the smallest possible web width or working width of the tensioning machine 1.
  • This arrangement is also such that - viewed in the top view of the web surface (as shown in Fig.1) - the light beams or light barriers 18, 19 with respect to the longitudinal center section 21 each diagonally (but essentially in the longitudinal direction of the Machine), with the light barriers on one side of the web cross the light barriers on the other side of the web, as can be seen in Fig. 1.
  • the light beams (light barriers 18, 19) on both sides of the web are thus directed towards each other.
  • the tensioning machine 1 designed in the manner described above is thus designed in an extremely advantageous manner so that it can be operated in the sense of a continuously constant product quality according to the inventive method explained in detail above. Quality-reducing contacts of the web 2 during their treatment in the tensioning machine 1 can thus be largely avoided.
