    • 专利摘要:
    A device to perform the cutting of weft threads in shuttleless looms provided with grippers for carrying the weft threads, in which a cutting blade arranged substantially perpendicular to the weft threads co-operates with a counter blade in respect to which it is operated under the control of cam means. In a first embodiment the blade is perpendicular and in a second embodiment it is parallel to the working path of the grippers.

    专利说明:

    The invention relates to the textile industry, namely, devices for cutting a weft yarn to an shuttleless loom.
    A device for cutting a weft yarn to a shuttleless loom is known; it contains a movable and fixed knife / installed parallel to the direction of movement of the weft thread plotters and a movable knife cam drive pi
    A disadvantage of the known device is the low reliability of its operation, due to the location of the cutting edge of the movable knife.
    The purpose of the invention is to increase reliability.
    This goal is achieved in that the B device for cutting the weft yarn to an shuttleless loom containing movable and stationary knives mounted parallel to the direction of movement of the weft yarn plotters and the movable knife cam lobe, the cutting edge of the movable knife located in a plane parallel to the plane of movement of the plotters, and set at an angle to the direction of movement of the plotters.
    FIG. 1 and 2 are isometric. device mounted on the machine; in fig. 3 movable knife.
    A device 1 for cutting the weft yarn is mounted on the supply side of the shuttleless loom with a continuous power supply with the weft threads after the selector 2 and the feeding 3 devices.
    The device 1 for cutting the weft yarn consists of a lever 4 pivotally mounted on axis 5. A lever 4 is rigidly attached to the lever 4 with a hook 7 mounted on it to grip the thread, the lower part of which is a fixed knife 8. On the free end of the lever 4 on axis 9 is mounted roller 10, placed in the groove 11 of the slot cam 12 mounted on the drive shaft 13. In the hole of the lever 4, axis 14 is freely mounted, at one end of which the holder 15 of the movable knife 16 is rigidly fixed. At the other end of the axis 14 is a bracket one 7, a carrying roller 18, a contact with a working surface 19 of an end cam 20. There is a protrusion 21 on the working surface 19 of the cam.
    On the axis 14 between the bracket 17 and the lever 4, a return spring 22 is installed. To increase the reliability of cutting the weft yarn, the cutting edge 23 of the movable knife 16 is angled to the direction of movement of the plotter 24 in a plane parallel to the plane of movement of the plotter.
    The device works as follows.
    The weft thread, selected by the selective 2 and captured by the feeding device 3, is inserted by the plotter 24 of the weft thread into the shed of the loom.
    The device in the drawings is shown in a lowered position so that the hook 7 guides and holds the weft yarn to be laid with its notch. At the stage immediately following the stage shown in FIG. 1, the cam 20, with its protrusion 21, fastens onto the roller 18, causing the axis 14 to rotate and, accordingly, lowering the movable knife 16. The cutting edge of the movable knife 16 slides along the side surface of the stationary knife 8 and, interacting with its cutting edge, cuts the weft thread .
    Immediately before the thread is cut, the plotter is moved in the direction of § 3 to a position sufficient for reliably inserting the thread into the seam of the plotter. Thus, thread trimming is performed only after the thread has been inserted and supported by the rounded portion of the hook 7, which eliminates the possibility of thread trimming before or simultaneously with the thread insertion.
    The slot cam 12 provides for raising and lowering the yoke hook onto the path of movement of the weft thread.
    Using cam control to rotate the device in tse; scrap and. The rolling knife allows you to accurately calculate working cycles, which ensures high reliability of operation. .
    In addition, the proposed device is distinguished by its simplicity of design and adjustment.
