Definitions
- the present invention is referred to as a title indicating a system for regulating the tension of threads or fabrics in textile machines, said machines being the type of which have reels for the supply of thread or for the collection of tissue, means of actuation of the reels and guide rods on which the threads or fabrics rest on their path towards the fabric zone of the machine in the case of the threads, or towards the reels of collection in the case of the fabrics.
- the feeding of threads that come from reels aligned and coupled to drive means responsible for causing the simultaneous rotation of all of them is carried out simultaneously.
- the threads coming from the spools define parallel paths at their entrance to the fabric area of the machine, based on guide rods that determine their trajectory.
- Some of these systems are intended to measure and control the amount of thread removed from the spools, varying the speed of rotation of the spools, for which it is necessary take into account a series of parameters such as the type of stitch that the machine is knitting, the nominal diameter of the reels or the length of thread supplied at each turn of the reel, since this length depends on the amount of thread remaining in Every moment on the reel.
- the tissue from a reel moves frontally against a static blade that cuts it along its longitudinal median plane, obtaining the two pieces mentioned above from the initial fabric. These pieces are separated laterally, resting on guide rods in their trajectory towards drag rollers and reels in which they are finally wound.
- the system object of the present invention presents constructive particularities oriented to solve the problem set forth in the previous section both in regard to the controlled supply of yarn in knitting machines, as well as to the tension of the fabrics in the mentioned cutting machines.
- This system is applicable to those textile machines that have thread reels or fabric pickers, means for driving the reels and guide bars on which the threads or fabrics are supported during their movement, based on the operation of the system in the regulation of the tension of the threads or of the fabric.
- this system contemplates the particularity that at least one of the guide bars of the textile machine is mounted by means of supports on sensors that generate signals proportional to the thrust communicated by the threads or by the fabric to said guide bar; said signals being, therefore, proportional to the tension of the threads or of the tissue to be controlled.
- the aforementioned sensors are related to the means of actuation of the reels through control means that receive the signals coming from the sensors and that generate according to them some control signals of the means of actuation of the reels, with In order to vary its speed of rotation and permanently maintain the tension of the threads or the fabric within the predetermined values.
- This system provides a number of advantages, such as the possibility of easily incorporating it into new machines and used machines, or ensuring, by means of tension control, a uniform collection of the fabric in RASCHEL type double-front fabric cutting machines and a Correct feeding of the threads in knitting machines, without having to take into account other parameters such as the thickness of the thread, the diameter of the spool or the amount of thread remaining in each moment in it.
- the reel drive means can rotate in opposite directions causing, depending on the control signals, the rotation of the reels at a variable speed in a forward direction or in a reverse direction to ensure the maintenance of the tension of the threads of the fabric within the predetermined values during the operation of the machine.
- This feature allows you to automatically adjust the tension of the threads in the weaving machines after it has been stopped for a certain time, so that when you start working the tension of the threads will be correct, avoiding the appearance of the tares that are they usually occur in the tissues when the weaving machine starts working.
- the guide bar supports are arranged radially and in coincidence with the bisector of the angle formed by the threads or the fabric in their support with respect to said guide bar, the thrust communicated by the threads or the fabric to said guide bar being transmitted perpendicularly to the sensors.
- FIG. 1 shows a schematic profile view of the system object of the present invention.
- FIG. 2 shows a schematic profile view of an application of the system object of the invention in a knitting machine by warp.
- FIG. 3 shows a schematic view of the system object of the present invention applied in a RASCHEL fabric cutting machine with double front.
- the system object of this invention contemplates that one of the guide rods (1) of the textile machine, on which the threads or the fabric (2) whose tension is to be regulated is supported, It is mounted by means of supports (3) on sensors (4) that detect the tension of the threads or the fabric (2) depending on the thrust exerted by the guide bar (1) on the sensors (4).
- the sensors (4) are related to the driving means (5) of a reel (6) through control means (7).
- the sensors (4) generate signals proportional to the tension of the threads or the fabric (2) that move on the guide bar (1), while the control means (7) generate, depending on the signals coming from of the sensors
- control signals of the drive means (5) causing the rotation of the spool (6) at a variable speed, in one way or another, in order to keep the tension of the threads or the fabric (2) within predetermined values.
- the system object of the present invention applied to a weaving machine can be observed, being used in this case to regulate the tension of the threads (2) supplied by the spools (6) towards the tissue area, where the needles (8) of the machine are located.
- the system object of the invention is applied on a tissue cutting machine
- RASCHEL of double fronture being mounted the guide bars (1) on the sensors in charge of controlling the actuation means (5) that cause the drag of the tissues (2) and consequently the tension of the same.
