    In an apparatus for joining textile threads with the aid of compressed air, there is provided a device for checking the tearing strength of the joint zone of the threads before their extraction from the apparatus. The device comprises at least one mobile member arranged to act on the loop formed by the joined threads with a predetermined traction force at an intermediate point between the points at which the threads are locked at the apparatus inlet. Control means are provided which are operated so that they travel through a predetermined outward and return stroke and act on said mobile member by way of a yieldable coupling which is set to yield when the predetermined traction force is exceeded.

    2. The device according to claim 1, about tl and - so that it has two spring-loaded telescopic sleeves and a rod, placed inside the sleeves with the stop dp in cooperation with one of them,
    This invention relates to the splicing of textile yarns using I
    compressed air
    Devices of this type are widely used in recent times and are partially replaced by conventional nodular devices. The advantage of these devices over knotted ones is that the textile yarns are spliced together without forming a knot by simply moving and interpenetrating the fibers under the action of a gust of compressed air fed into the mixing chamber.
    However, splicing textile yarns with compressed air only is a very complicated process. The result of the work is decisive, its influence on the location of the threads to be mixed in the mixing chamber, the length of their free ends, the duration of the impulse to supply air, as well as many other factors. There are also variable factors that are difficult to control, such as the textile characteristics of threads.
    The purpose of the invention is higher reliability of the device.
    On ftdg, a device is schematically shown with connected yarns that are fed from the same side, front view; Fig. 2 is the same, however, the threads are fed from opposite sides; on fig.Z - the device of figure 1, front view; figure 4 is a device according fig.Z, side view. The device dp of connecting textile fabrics by means of compressed air contains a mixing chamber 1 formed in the housing 2, which is open on both sides and in front, where it can be closed tightly with the cap 3, the tube 4, waste
    the control lever is connected to another hub, and the stem is connected to the hook.
    3. The device according to PP.1 and 2, about t - is fueled by the fact that the lever is driven by a cam.

    from the source of compressed air enters chamber 1. It has a cut-off valve 5, which creates a pulse of compressed air, sold to chamber 1 for a predetermined period of time, to connect two threads
    6 and 7 by mixing and weaving their fibers.
    The clamping means 8 and 9 are installed at the places where the threads 6 and 7 to be connected enter the device.
    The difference between the implementation of the devices shown in FIGS. 1. and 2 is that in the first device two strands 6 and 7 enter the body 1 on the same side, so that the clamping means 8 and 9 are located On the same side, while in the device shown in Fig. 2, the threads 6 and 7 enter from opposite sides, therefore the means behind the arms 8 and 9 are also located on opposite sides of the casing.
    FIG. 2 scatum1 represented, a state in which two 1sti b and
    7 are still in the mixing chamber 1, the cat oracle is in front closed with a crinkle, but already interconnected in the zone
    A (this situation occurs immediately after the splicing stage). The threads b and 7 are still clamped in the places where they enter the body using the clamping means 8 and 9. The shut-off valve 5 is closed,
    This moment corresponds to the position before the connected threads exit from the device, in which there is a means for controlling the tensile strength in the zone of the connection of the threads.
    In the present embodiment, this. the tool contains two mobile ka 10 and 1 G. intended for pri-; lagging beyond / .1, anneal force

    To the loop formed by connected joints at two intermediate points located close to the corresponding exit points from the mixing chamber 1, between the entry points to the device where the clamping means 8 and 9 are located, this increasing force tends to disengage the resultant connection.
    Each of the movable elements 10 and 11 is provided with control means (Figures 1 and 2). They are articulated levers 12 and 13, respectively, driven by means that are not shown, turning at a given angle, first in the direction of the arrow and then in the opposite direction. Lever 12 or 13 acts on the corresponding movable element
    10 or 11 is not direct, but through a spring clutch, which is springs 14 and 15, respectively.
    When the levers 12 and 13 rotate in the direction of the arrows, the springs 14 and 15 are loaded and the load is transferred by means of hooks 10 and P to the loop formed by connected threads that are clamped between means 8 and 9. If the connection is between threads 6 and 9 7 good, i.e. if the resistance to the specified pulling force is sufficient, then the elements 10 and 11 remain at rest, and the springs 4 and 5 are simply compressed, so the levers 1Zi and 13 can perform a full stroke outwards. The levers are then returned to their original position, the connection has passed the test. The connected yarns can be exited from the device with the certainty that the splicing zone A could withstand the action of a given pulling neck.
    If the connection between threads 6 and 7. is of poor quality, then elements 10 and
    11 under the action of the springs 14 and 15 begin to move in the direction of the arrows, the threads 6 and 7 in the zone A of the splicing process are broken. The stroke of the elements 10 and 11, which they make under the action of the rotation of the levers 12 and 13 is such that the defective connection is broken, i.e. The threads 6 and 7 are separated from each other, thus preventing the possibility of being removed from the device by certain 74 74
    honest compound. In this case, the connection must be repeated. One of the variants of the device is shown in FIG. 3 and 4.
    5 The device also contains a mixing chamber 1, located in the housing 2, and a cover 3.
    The tube supplying compressed air to chamber 1 as well as the shut-off valve 10 are not shown. Means 8 and 9 are available for strands 6 and 7 at the points where they enter the device.
    On the device’s case there are pins 16 and 17 on its two sides, around which the articulated levers 18 and 19 turn, respectively, on the inserts 20 and 21, on the other ends of the levers there are coraciform parts 22 and 23, which correspond to the form 20 of the case, in the initial position, in a plane parallel to the plane of the levers 18 and 19 on the inserts 20 and 21, the levers -24 and 25 are mounted, which are hinged on the pins 26 and 27, 5 connected to the forked ends 28 and 29 of the rods, 30 and 31. These rods are equipped with two sleeves 32, 33 and 34, 35, respectively, they can telescopic Skis move relative to each other under the action of springs 36 and 3: 7, respectively. The outer sleeve 32, 33 is adjacent to the forked end 28, 29, respectively, of the stem 30, 31. In the rods 30 and 31 there are central longitudinal through slots 38 and 39, and at the ends opposite to the forked ends, stoppers 40 and 41 are installed. Heads 42 and The 43 levers 44 and 45 are attached to a common shaft 46 mounted rotatably in the device case, with the heads inserted in slots 38 and 39, and the heads 42 and 43 are located between the inner sleeve 33, 5 and 35, respectively, and the stopper 40, 41, respectively. to her stock 30, 31.
    The lever 47 is attached to the shaft 46 on one side of the device (FIG. 4); at its end there is a roller 48, which is inserted into a profiled cam groove 49, which is made at the end of a disk 50 rigidly fixed on the drive shaft 51 of the device; 5, the shaft rotates the direction of the arrow in FIG. 4,
    The profiled groove 49 has the shape of a circle 52 over
    five
    a certain sector, then has a descending part 53, behind which there is a part 54 raising to the level of a circle.
    When the roller 48 of the lever 47 is in part of the profile 52 in the form of circumference, the levers 44 and 45 are rotated to the position shown in Fig. 3 and 4. This is the initial position of the control means, which takes place during the complete splicing cycle by the device. In this position, the beak-like parts 22 and 23 are supported against the body 2.
    At the end of the connection cycle, when the crown 3 is still in the closed position, and the elements 8 and 9 are still in the places where they enter the device, the connecting zone A of the two threads 6 and 7 is in the mixing chamber 1, the control device is driven by the roller 48 of the lever 47 enters the descending part 53 of the groove 49, whereby the levers 44 and 45 are forced to rotate counterclockwise (Fig.4), the heads 42 and 43 of the levers. 44 and 45 act on the inner bushings 33 and 35 and push it to the left, with: Kim corresponding to 36 and 37, Next, the force is applied to the forked loops 28 and 29 of the rods 30 and 31, which tend to turn the levers 24 and 25, as well as the levers 18 and 19 in the direction in which the knuckle-winged sections 22 and 23 are retracted from the 7th orbits. Thus, a predetermined force, which tends to break the connection of the threads, is applied to the beams of the 22 and 23 to the connected threads 6 and 7, which come to the side of the coraco-shaped part 22 and 23.
    If zone A of the joint pulls out this pulling force, the beak-shaped parts 22 and 23 supported by strands 7 and 6 pressed against the housing 2 and the rotation of the levers 18, 24 and 19, -25, respectively, does not occur, resulting in rods 30 and 31 with its outer sleeves 32 and 34 are also extended in place. However, levers 44 and 45 can still perform

    6 and 7 are freed from the means of the clamp 8 and 9 and the connected threads impose.
    However, if Zone A is poor in quality and does not withstand the relieving force applied to the connected nitrous beams like 22 and 23, then the levers 18, 24 and 19, 25 correspond to the strength of the levers 44 and 45 and the springs 36 and 37
    20. Begin to rotate, and the coracoid portions 22 and 23 are retracted from the housing 2, with this breaking the joint and separating the two strands 6 and 7.
    25 The turn of the aforementioned levers 18,
    24 and 19, 25, which means that 1 shlyuvovidnyh parts 22 and 23 is such that it ensures the complete separation of two threads 6 and 7 and the uncoupling of the defective
    30 compounds.
    After this, the control means returns to its original position, and the device completes the working cycle, but the threads 6 and 7 are not interconnected between themselves, when they are forced out of the device, therefore all the work on soiling should be repeated.
    The control means provides at least 40 resistance to this tensile force in the thread joining area at the end of the working edge of the device; however, if this resistance is not maintained, the device disengages the defective connection and separates the thread.
    Thus, for control, no additional operations are required, and the control stage is introduced into the operating cycle of the device.

    In the presented embodiments, the specified pull force, at which the control is at rest, is fixed, it is determined by adjusting the springs 36 and 37. If the magnitude of this force is
    If a given rotation by a simple change is necessary to change, then both springs are.
    The inner sleeves 33 and 35 and the compression of the springs 36 and 37. When the roller 48 enters the lifting part 54
    should be replaced. However, it is possible to install a means to control
    tension springs.
