Definitions
- the invention relates to a singeing machine of the type corresponding to the preamble of claim 1.
- the working speed ie the speed at which the yarn strands are conveyed in the longitudinal direction through the singe burner, is in the order of magnitude of 300 to 1000 m / min. Singeing is mostly used for yarns with fine hairs protruding from their surface, for example, yarns made from natural fibers or spun yarns. Protruding from the yarn surface The hairs are burned off or melt or bake together to form particles that initially have the speed of the yarn strands and move with them in the same direction.
- the invention is therefore based on the object of improving the operation of a generic singeing machine.
- the basic idea expressed here is to remove the moving particles so that they can no longer impact and bake on, but can be collected and disposed of in a manner that is harmful to the operation of the singeing machine. This can be implemented in the manner set out in claim 3.
- the particles of material that have been seared in the scorching torch like the individual strand of yarn itself, must be passed through the air for a period of time without contact, so that the particles and the yarn surface are solidified by cooling to such an extent that there is no longer any stickiness, i.e. there is no longer a tendency to bake or cake.
- the particles do not have to become completely hard, but should no longer show any tendency on their surface to adhere to an adjacent surface or an adjacent particle.
- a device which catches the particles flying along with the yarn strand in a kind of spray jet in such a way that they can be removed from the machine without covering the machine from the inside and gluing guide elements.
- the device can comprise an open container into which the particles moving with the yarn can fly.
- This container has an opening cross section for each yarn strand or each group of yarn strands which is sufficient to accommodate the entirety of the flying particles which have been seared.
- the singe burner as it were, in an upper "corner" of the housing of the singeing machine and the diagonal guidance of the yarn strands in the housing cross section allow a maximum cooling distance to be accommodated in a housing of a certain size.
- the inclined yarn strand guide already leads to a first separation of the entrained, sunk particles from the yarn strands, because the particles cover a parabolic trajectory under gravity.
- the opening of the container must extend over the entire area in which the flying or falling particles can arrive. A filled container can be quickly replaced with an empty container while the singeing machine is in operation.
- the end of the cooling section is formed by deflecting rollers, on which the yarn strand or the yarn strands are deflected into an upward stretch in order to be able to get out of the area of the opening of the container and be passed on.
- the deflection at the deflection rollers takes place at an acute angle. Particles still adhering to the yarn are thrown off by this abrupt change in direction and also get into the container.
- a noticeable after-cooling takes place in the upward stretch, so that the yarn strands can cool down further until they are conveyed to a downstream unit.
- a length of the upward path of one third to two thirds of the length of the cooling path is mentioned in claim 7.
- the inclination angle of the thread strand or the thread strands in the cooling section depends on the structural conditions. According to claim 10, it should be 45 ° to 75 °.
- the deflection rollers provided for each individual yarn strand at the end of the cooling section and also at the end of the upward section should be in the contact area of the yarn strand, eg. B. in the reason of an existing guide groove, diameter of about 15 to 30 mm (claim 11), whereby the deflection rollers at yarn speeds of 300 to 1000 m / min receive very high speeds in the order of approximately 5,000 to 20,000 min "1 , which means that any particles that tend to stick will be thrown off and the deflection rollers can be kept clean in this way.
- the configuration according to claim 12 is recommended. In this way, the supports have moved out of the area of the yarn and the cut particles.
- Claims 13 to 16 represent constructive configurations of the deflection rollers and their shafts.
- the flame gases can be led out of the housing of the singeing machine.
- the flame gases have a tendency to rise due to their temperature, towards the suction device. Together with the fact that the seared particles fall down under the effect of gravity, this promotes the separation of the flame gases from the seared particles.
- a spray device in the area of the cooling section, by means of which a fluid medium can be sprayed onto the running yarn strand.
- the fluid medium can be air, water or the like and support cooling.
- the subject of claim 19, namely the regulation of the scorching effect by means of a temperature measurement, contributes in the sense of an optimal separation of the entrained silted particles, insofar as in this way any excessive temperature rise above the value necessary for the singeing is avoided and the cooling section actually cools down to sufficient to solidify the particles.
- Fig. 1 shows a side view of the singeing machine according to the invention
- FIG. 2 shows a view according to FIG. 1 from the left on a reduced scale
- 3 shows a perspective detail from the area of the deflection rollers
- the singeing machine designated as a whole in FIG. 1 comprises a machine housing 1 in which, in the exemplary embodiment shown, six adjacent burner units 2 are accommodated, which are indicated in FIG. 2 only by their center lines.
- Each burner unit has a singe burner 10, in which, in the exemplary embodiment, four yarn strands 3 lying one above the other are seared.
- the singe burner can e.g. B. in the manner described in EP 814 185 A2.
- the yarn skeins are brought up at 4 and deflected obliquely downwards in the interior of the machine housing 1 at 5 by corresponding deflection rollers, not shown in detail.
- the yarn strands 3 then pass the gas-heated singe burner 10 lying one above the other in a plane, the gas flames being generated at the end 6 of the singe burner 10 and having a flame direction extending parallel to the conveying direction 7 of the yarn strands 3.
- the flame gases exit at the end 8 opposite the inlet end 6 together with the yarn strands 3 in the direction 7 from the singe burner 10.
- the singe burner 10 of each burner unit 2 is arranged in the area of the upper right corner of the housing cross section shown in FIG. 1, which essentially has the shape of an upright rectangle.
- the conveying direction 7 extends obliquely downwards, that is to say approximately diagonally to the housing cross section shown, up to deflection rollers 9, which are only indicated in FIG. 1 and are only indicated in FIG. 1, and shown in detail in FIGS. 3 and 4 from the upper pulleys 5 to to the lower guide rollers 9 straight and non-contact running yarn strands 3 with the horizontal an angle 11 of about 60 °.
- the deflection rollers 9 deflect upwards at an acute angle 12 up to the upper deflection rollers 13, at which the yarn strands 3 are led out of the housing 1 in the direction of the arrow 14.
- the yarn strands 3 cover a cooling section 15 up to the deflection rollers 9, which in a specific exemplary embodiment has a length of approximately 1.40 m.
- the cooling section 15 is followed by an upward section 16, which in the exemplary embodiment is approximately half as long.
- the skeins of thread 3 consist of a thermoplastic spun-fiber carpet yarn, on the surface of which unshaved fine hairs protrude, which cause a very annoying lint formation when the carpet is finished and also when it is subsequently used.
- the above hairs are burned or melted when passing through the singe burner 10, in which the temperature is very high, and fly along with the yarn strands 3 in the direction 7.
- the seared particles are still sticky-plastic, but cool down on the cooling section 15 to such an extent that they lose their stickiness at least on the surface and no longer have the tendency to fall on an impact surface or another particle cling to.
- the sump 20 also detects sunk particles which are thrown off the deflection rollers 9 for the respective thread strand and which have a diameter of only 15 to 30 mm and which still adhere to the surface of the thread strand.
- the collecting container 20 can be pulled out of the machine housing and emptied in the direction of arrow 18 during the operation of the singeing machine 100 and emptied or can be replaced by an empty container.
- the essential thing about the guidance of the yarn strands 3 following the singe burner 10 is that the yarn strands 3 and the entrained particles entrained with them are directed into the container 20 and cannot adhere to the housing wall or guide elements for the yarn strands 3.
- a suction device 21 is provided in the form of a roof-shaped collecting element 22 which extends across the cooling sections 15 of the burner units 2 and which exits from the singe burner 10 in the direction 7 via a fan 23 (FIG. 2) and after leaving of the singe burner 10 sucks up moving flame gases and removes them from the interior of the machine housing 1.
- the blower 23 is mounted on the top of the machine housing 1 in the embodiment, as is a blower 24 which supplies the six singe burners 10 with combustion air via a line 25.
- Fig. 3 the area of the lower guide rollers 9 is shown separately again.
- the shafts 27 of the deflection rollers 9 extend 4 apparent form. They have a V-shaped circumferential groove 28, in the base of which a guide groove 31 is worked out for the respective skein 3.
- the V-shape of the circumferential groove 28 helps to guide the sunk particles away from the yarn strand 3.
- a separate deflection roller 9 is provided for each strand of yarn 3, the shafts 27 of which in the exemplary embodiment in FIG. 4 are mounted on bearings 29 in the side support plates 26.
- the distance 30 from the guide groove 31 in the axial direction of the shaft 27 to the respective bearings 29 is at least 5 cm, so that the bearings 29 remain out of the area of the yarn strands 3 and the sunk particles moving with them.
- the diameter 32 of the guide groove 31 is about 15 to 30 mm, so that the guide rollers 9 rotate at the usual conveying speeds of the yarn strands 3 in the order of 300 to 1000 m / min at a speed of about 5,000 to 20,000 min "1 , which is sufficient in order, for example, to prepare ready-to-stick particles cut off from the respective skein 3 so that the deflection rollers 9 experience a self-cleaning effect in this way.
- FIG. 5 An alternative embodiment is shown in FIG. 5.
- the shaft 27 'does not rotate with this.
- the deflection roller 9 ' is mounted on bearings 29' on the fixed shaft 27 '.
- the deflection roller 9 ' also has a circumferential groove 28 with a guide groove 31. The dimensions correspond to those in FIG. 4.
- a spray device 19 is provided in the area of the cooling section 15, from which a water mist or cooling air can be directed onto the running yarn strands 3 to support cooling.
- a temperature transducer 33 is provided, which detects the temperature of the emerging yarn strands 3 or the escaping flame gases and whose signal is fed via line 34 to a regulator 35 which regulates the internal burner pressure and thus the singeing effect.
