Definitions

  • the invention relates to a method for the automatic or semi-automatic separation of matched textile parts, in particular knitted parts, the separation points of which are provided with melt separating threads, in which the textile parts are subjected to a heat treatment, by means of which the melt separating threads are melted, whereby two parallel adjacently matched threads are melted After the melting of the separating thread connecting them, textile parts are completely separated from each other by accelerating the part of the fabric lying in front in the direction of movement of the fabric by pressing a conveyor against the adjacent trailing part of the fabric, the textile parts to be separated being placed on a lower part Conveyor belt are moved under the conveyor.
  • the invention relates to a device for performing this method with an finishing device through which the fitted textile parts pass and in which they are subjected to a heat treatment through which fusible separating filaments can be melted, the finishing device being followed by a separating device which is one with those to be separated Has parts of material that can be brought into contact with a conveyor, under which the parts of the material to be separated can be moved past on a lower conveyor belt.
  • the fabric part located in the direction of movement of the fabric parts at the front is accelerated by pressing a roller device against the adjacent, trailing fabric part, the textile fabric parts to be separated being moved forward with a conveyor belt under the roller device, which consists of two parallel, rotating rollers, the first of which is trailing
  • the roller rotates at a peripheral speed corresponding to the conveyor belt movement speed and the second leading roller rotates at a higher peripheral speed, whereupon both rollers are lowered onto the conveyor belt and briefly pressed onto the textile fabric parts on both sides of the melted separating thread and then raised again after separation of the fabric parts will.
  • both rollers are lowered onto the conveyor belt and briefly pressed onto the textile fabric parts on both sides of the melted separating thread and then raised again after separation of the fabric parts will.
  • two adjacent separating threads are melted. Tied together textile parts until the melted separating thread breaks off.
  • a fabric web consisting of a plurality of fabric parts arranged one behind the other and connected by fusible separating threads is conveyed by a roller-driven conveyor belt into a gap formed by two superimposed rollers and from there reaches the surface of a driven roller , on which the fabric web is acted upon by hot air jets emerging from a heating device, whereupon it reaches the feed nip formed by the roller and a counter roller.
  • the part of the fabric drawn into the nip of the rollers is separated from the subsequent web, then conveyed through the nip and placed on a conveyor belt running under the rollers.
  • the object of the invention is therefore to modify the method of the type mentioned so that not only a perfect separation of rugs, knitted or knitted fabric parts, which are connected with melt separating threads, is achieved after the finishing process, after melting the threads and Separation of the matched parts should also result in a complete evaporation of the thread material, so that there are no longer any material residues at the edges of the fabric part, but this procedure is also carried out in a manner that is more gentle on the product, so that there are no reductions in quality.
  • a device is to be created with which the stated method objectives can be achieved in a less costly manner.
  • the conveyor consists of two upper, one after the other, endless, in the same direction as the lower conveyor belt conveyor belts, of which the front in the direction of movement of the fabric parts, first with the material to be separated in contact entering conveyor belt has a lower speed than the rear conveyor belt, the speed of which corresponds to that of the lower conveyor belt, the melt separation threads of the interconnected, between the upper and the lower conveyor belt parts of fabric clamped under the influence of heat, the more they advance towards the front upper conveyor belt, and finally melted with the separation of the neighboring fabric parts and then gripped by the upper front conveyor belt and from the Separation area are promoted.
  • a device in which the conveyor consists of two upper, endless conveyor belts arranged in a row, which run in the same direction as the lower conveyor belt and of which the parts when entering the device first with the Front conveyor belt coming into contact with fabric parts has a lower movement speed than the rear conveyor belt coming into contact with them after separation of the adjacent fabric parts, the movement speed of which corresponds to that of the lower conveyor belt.
  • the essential idea of the invention thus consists in separating the textile parts connected to one another by melt separating threads when these threads are melted in that shear forces are transmitted between their upper side and their lower side due to the speed difference of the conveyor belt surfaces in contact with these sides, which shear forces are transmitted to the neighboring ones Pull pieces of fabric apart and finally cut through the melted separation threads, after which the parts separated from each other are inevitably pulled out of the separation zone by the upper second conveyor belt running in synchronization with the lower conveyor belt.
  • the knitted, fitted fabric parts which are denoted by 11 in Fig. 2, are provided at the separation points with knitted melt separating threads 10, which are indicated in Fig. 2 as dashed lines.
  • the fabric parts are, for example, trimmings for cardigans and sweaters. These fabric parts pass on the lower conveyor belt 1 in the direction of arrow A in Fig. 1 from left to right and in Fig. 2 from right to left the finishing machine 5, in the upper part 4 of which the two upper conveyor belts 2 and 3 are arranged in series are, which are driven via guide and deflection rollers 7, 8 in the direction of arrows B, D in the same direction with the lower conveyor belt 1, which also runs over 8 deflection and guide rollers in the direction of arrow C.
  • a heat treatment takes place in the finishing device, in which the melt separation threads 10 melt under the action of steam and at least partially evaporate.
  • the steam is removed from the upper part 4 at 9.
  • the cloth parts 11 to be separated are clamped between the opposing endless conveyor belts, the front upper conveyor belt 2 having a lower forward movement speed than the lower conveyor belt 1, while the rear upper conveyor belt 3 has the same forward movement speed like the lower conveyor belt 1.
  • the rear upper conveyor belt 3 is shorter than the front upper conveyor belt. The latter is also provided with a roughened surface, while the surface of the other two conveyor belts 1 and 3 is smooth.
  • the fabric parts 11 connected by the melt separating threads are drawn further apart in the region of the front upper conveyor belt the further they run into the device on the lower conveyor belt 1, whereby after the separation threads have melted, they separate from the subsequent colder ones Detach pieces of fabric. In any case, this is the case before the end of the front upper band 2 is reached.
  • the separated fabric parts are then gripped by the smaller rear upper conveyor belt 3 and inevitably transported out of the separation zone so that they assume the arrangement shown in FIG. 2 on the left side of the upper part 4 on the table 6 of the finishing device 5.
  • the separation process itself hardly differs in terms of the temperature prevailing in the finishing device and the amount of steam required from the usual, normal finishing process, which means that, for example, in the cases where the textile parts consist of acrylic fibers with temperatures slightly above 100 ° C, with polyester fibers with temperatures between 140 and 150 ° C and with mixed fibers with temperatures between the ranges mentioned.
  • the conveyor belt speeds are adjustable, with a speed ratio being set between the front upper conveyor belt 2, which runs at a lower speed than the other two conveyor belts, which have the same speed, the smaller the longer the individual fabric parts, for example is used for sweater and cardigan trimmings with a width of approx. 2 cm at a speed for the lower conveyor belt 1 of 4 m / min. driven while the front upper conveyor belt 2 a belt speed of 3 m / min. has, ie 25% slower.
  • the method described and the device used for its implementation make it possible to achieve a clean separation of successive, matched textile parts, in particular knitted parts, upon complete evaporation of the melt separating threads, without requiring too much process engineering or technical equipment. No melt thread remnants remain on the knitted part edges and the separation process itself does not undesirably change the structural properties of the goods, such as thickness, pattern, position.
