    A method and apparatus for transferring a limp fabric piece (6) wherein the fabric piece (6) is deposited on a low frictional plate (7) supported by a movable carriage (not shown) mounted on wheels (10). The carriage is then moved to a position (2) beneath a frictional gripping device (9) which is then lowered onto the fabric piece (6). The carriage with the low frictional plate (7) is then withdrawn from beneath the gripping device (9) and returned to its original position (1) leaving the gripping device (9) in frictional engagement with the fabric piece (6).

    专利说明:

    The invention relates to the clothing industry, in particular, to a method for moving a piece of soft fabric and a device for carrying it out.
    The aim of the invention is to increase productivity.
    FIG. 1 shows a diagram of a method for transmitting a soft tissue piece in three stages from position I to position II; in fig. 2 - a device for transferring soft tissue; in fig. 3 shows a variant of the friction engagement device at various stages before and at the time of contact with the piece of fabric.
    The method is carried out as follows.
    A piece of fabric 1 is fed by an appropriate device to the upward moving lower friction surface of platform 2. Platform 2 is made rigid, preferably made of metal, for example aluminum, the working surface of the platform being polished,
    so she had a low coefficient of friction. The platform has a means for its reciprocating movement and is equipped with a large number of wheels.
    3 that move along two rails
    4, extending to the position located by the substructure 5, along which the piece of fabric will move, subject to various manufacturing processes to sew. In position II, platform 2 is positioned so that a piece of fabric 1 is directly below the friction surface 6 to grip a piece of fabric 1 in order to ensure further advancement. The frame 5 has two notches (not shown) through which free access to the wheels 3 is provided. The upper surface of the frame 5 also has a relatively low coefficient of friction and is best done in the form of polished metal or use one of the well-known polished sheets for this with

    corresponding laminate. When platform 2 reaches position II, it will be placed on the flat part of village 5 and can freely slide along it.
    The platform 2 supported by the carriage has means for its reciprocating movement between positions I and II. The carriage movement can be carried out using a pneumatic piston cylinder, whose operation is adjusted so that the reciprocating movement of the platform 2 between positions I and II is in time dependence with other operations of the sewing machine.
    The device also contains a receiving device 6 comprising two flat elements placed one above the other, one of which has a friction surface to grip the fabric, and the other is the working surface of the frame 5. The receiving device can be moved by clamps 7 mounted by means of levers 8 connected to an executive mechanism 9. The position of the clamps 7 is oriented relative to the receiving device by means of pins 10. A conveyor system 12 is mounted on the frame 11.
    The device works as follows.
    Initially a piece of cloth is placed on platform 7 with an appropriate fixture. In addition, on the platform 2, two pieces of fabric previously superimposed on each other can be successively arranged. After that, the platform 2 supported by the carriage moves away from position I and moves to position II by means of a pneumatic cylinder. After occupying the platform 2 with a fixed or stationary position in position II, the receiving device 6 is lowered onto the piece of fabric 1 (Fig. 3).
    The friction receiving device 6 can be raised and lowered by means of two clamps 7 mounted on lever 8, both clamps 7 and lever 8 being actuated to perform a clamping unclamping movement as well as an up and down movement using a pneumatic actuator. mechanism 9 mounted on the frame 10.
    The frame 10 also supports the conveyor system 12, by means of which a large number of friction receiving devices 6 are transferred to the clamps 7 for subsequent lowering them onto a piece of fabric 1 in position II,
    FIG. The position of the receiving device 6 is shown before the moment of its engagement with the clip 7 above the piece of cloth 1. In FIG. 36, the moment when the receiving device is clamped by the clips 7 but not yet lowered onto the piece of cloth is shown, and in FIG. Zg is the moment of engagement of the receiving device 6 with a piece of cloth which is currently supported by the bed 5
    after lowering the receiving device 6.
    The receiving device 6 has a friction surface to grip a piece of fabric, and this surface has the configuration of a piece of fabric 1. Moreover, the perimeter contour of the friction receiving device 6 is designed to copy the general outline of the perimeter of the piece of fabric and that only a relatively small part of the fabric outside the area or contact area of the friction surface of the receiving device (Fig. 3). The required degree of frictional clamping force between the friction surface of the receiving device 6 and the surface of the piece of fabric 1 can be achieved by coating or applying to the friction surface an appropriate material, which will be
    provide a high coefficient of friction. The most suitable material for this case is ordinary abrasive sheet material - sandpaper.
    The degree of frictional pressing force between the friction material and the fabric is such that the operation of the pneumatic cylinder, which is connected to the supported carriage of the platform 2, with
    the purpose of pushing this platform 2 in the direction from position II to position I will force it to slip out from under the piece of fabric 1, so that this piece of fabric 1 will gradually move along the frame
    5 until the fabric is fully located on it. Now the platform 2 supported by the carriage returns to position I as a result of the corresponding action or actuation of the pneumatic cylinder and is set to the ready state for receiving the next piece of fabric 1.
    Receiver 6 can be held in contact with a piece of cloth, and
    by moving the receiving device 2 in an appropriate manner along the frame 5, it will move the piece of fabric 1 along any previously prescribed route, which in
    ultimately determined by the movement of the receiving device 6.
