    The invention relates to textile engineering, in particular, to a device for separating a piece of fabric from a stack and transporting it to a receiving base.
    The purpose of the invention is povyenie reliability of the device.
    FIG. 1 schematically shows the main stages of transporting pieces of fabric; in fig. 2 - the device, a general view in axonometry; in fig. 3 is a section, A-A in FIG. 2; in fig. 4- the same, provided that two pieces of fabric are transported using the proposed device.
    The device has a supporting element 1 of a cylindrical phogm fixed to the shaft 2. The corresponding ends of the shaft 2 are supported on the lateral guides 3, the supporting element I. The means for providing the translational and rotational movements of the supporting element can be made in the form of teeth, resulting in rotation of the supporting element 1 is accompanied by its movement along the guides (Fig. 1). The support 4 is intended for raising and lowering relative to the guides 3, for example, under the action of a hydraulic cylinder 5. On the support 4 there are 4

    A stack of 6 pieces of fabric is laid. The support 4 has a fixed stop with which the end of the stack 6 interacts to ensure that the pieces of fabric are longitudinally positioned relative to the guides 3. The stationary plate 8 covers the end of the stack of fabric pieces near the end stop 7, so that when the support 4 rises under the deist - by twisting the cylinder 5, the end part of the upper piece of fabric is pressed down to the plate 8. The plate 8 is located at a predetermined distance below the level of the guides 3, so that regardless of the height of the stack 6, the upper piece of fabric from report card will always move in the same position relative to the guide nndih 3 every time, when the support 4 is raised.
    Friction 9 is mounted in the supporting cylindrical element 1 for rotation around its axis, which is parallel to the shaft 2. The diameter of the friction roller 9 and the position of its axis are chosen such that the surface of the roller slightly protrudes beyond the peripheral surface of the non-existing cylindrical element. Thus, when a stack of 6 pieces of fabric is in a raised position and the carrier 1 is positioned with the friction roller 9 vertically below the axis of the carrier, the surface of the friction roller 9 will be pressed against the upper piece of fabric in the stack 6 (Fig. 1) .
    In the sector of the cylinder {), the surface of the carrier 1 is filled with holes - perforations 10. The latter are located along the entire length of the core 1 of the core surface and usually take an arc of 90. This perforation 10 of the surface of the carrier element communicates with the chamber 11 inside the cylindrical carrier 1 which is connected to the vacuum source. Thus, by creating a layer of tissue in the dilution chamber 11, which is located on the perforation sector 10 of the surface of the carrier element, it will be kept on it until a vacuum is maintained in the chamber 11.
    At some distance from the support 4 along the guides 3 there is a receiving base 12 of a piece of cloth having a flat upper surface 13

    perforated. The perforated top surface 13 of the receiving base 12 communicates with the chamber 14 located under it, which is connected to a vacuum source, so that a piece of fabric placed on the surface 13 will be held on it when a vacuum is created in the chamber 14. The receiving base 12 may be part of a machine that performs an operation on a piece of cloth, or. it may be an intermediate device, such as a conveyor, on which a piece of cloth is first placed and prepared before being transferred to the machine.
    Bearing Element 1 is rigidly fixed on the shaft 2, at the ends of which sprockets 15 can be fixed. Each of the guides 3 has a longitudinal groove 16 in which the cable 17 with the corresponding sprockets 15 is located. The base of each groove contains a chain 17, with which the corresponding asterisk 15 interacts, so that the slippage between the asterisks 15 and the guides 3 is eliminated by itself (Fig. 2).
    The shaft 2 is connected to the end of the stem 18 of a double-acting hydraulic cylinder (not shown). This cylinder is mounted on the frame of the machine to which the rails 3 are attached. Thus, when the cylinder is actuated, the stars J5 move along the rails and the supporting element I rotates.
    The roller 9 is mounted in bearings 19, mounted on the respective end plates 20 of the carrier element 1. At one end of the roller 9 there is a lever 21 fixedly attached to it. The double-acting hydraulic cylinder 22 is connected at one end with lever 21 and the other with bracket 2.3 attached to end plate 20. Actuation of irylinder 22 ensures partial rotation of roller 9 around its axis, which is parallel to axis of shaft 2 and bearing member 1. The working medium of the cylinder 22 is supplied through the respective pipelines 24, passing through the cavity a shaft a 2,
    A strap 25 is attached to the supporting cylindrical element 1 parallel to the roller 9. The edge of the latter is located on some rails:

    from roller 9 to form a gap 26 (Fig. 3). The gap 26 has counter-lying parallel edges that are spaced apart from each other so that the fold of fabric fed into it as the roller 9 is rotated is caught between the bar and the roller. The surface of the roller 9 has freak1471945

    slippage between the roller and the upper piece of fabric in the stack 6, when the roller rotates, is in contact with the stack 6. The friction material also contributes to the capture of the fold of fabric fed into the gap 26.
    The peripheral walls 27 of the supporting member 1, located between the ends: - the plates 20 have a tsipindric form, but not around the whole circumference. Radial walls 28 extend from the respective edges of the peripheral wall to shaft 2 to form chamber P. Peripheral wall 27 is provided with perforations, the location and size of which is selected depending on the piece of fabric being transported and its type. In chamber 11, a vacuum can be selectively created a piece of fabric wound around the peripheral wall, during the movement of the carrier from the place where the piece of fabric is taken from the stack 6, to the place where it is laid on the receiving base 12.
    The receiving base 12 of FIG. (2 and 4) It is a belt conveyor 29 which tracks the section 30 of the upper leg, supported by rollers 31 and 32, which is flat and located between the guides 3 and parallel to them. This flat section 30 of the transporter is in the path of movement of the non-bearing element 1 when the sprockets 15 move along the guides 3, and the support element 1 can be mounted over the flat part 30 of the conveyor belt and transfer the carrier-side fabric to the exporter.
    Under the flat section 20 of the belt conveyor there is a box 33, which is open at the top and connected by a lang 34 to a source of discharge. The belt conveyor is made of an air-permeable material and it contacts with the upper front edge of the box 33. When the box 33 communicates with a vacuum source,

    The device works as follows.
    When the carrier 1 is placed on (Fig. 1) by a friction roller 9 projecting at its lower point, the support 4 with the stack of 6 pieces of fabric rises, with the result that the upper piece of fabric in the stack 6 is pressed against the plate 8 and the friction roller 9, 20 the latter is then partially rotated counterclockwise (Fig.). When the roller 9 is rotated, the front edge of the upper piece of fabric comes out from under the plate 8 and on the opposite side of the roller 9 forms a fold.
    This crease extends into the gap 26 between the surface of the roller 9 and the longitudinal edge of the peripheral surface of the carrier, located directly next to the roller 9. The width of this gap is chosen depending on the transported fabric, so that when the fabric debugging is pushed into the gap is caused by the friction roller 9, then a sufficient grip of the fabric takes place to hold it in this position, while the remaining part, the piece of fabric, is wrapped around the supporting element 1.
    As soon as the frontmost part of the piece of fabric is held in the gap with the help of the friction roller 9, the carrying cylindrical element 1 begins to rotate clockwise, (Fig. I), as a result, it will move along the guides 3 and simultaneously roll along the surface of the upper piece the fabric in the stack 6. Since the front edge is captured by the carrier element, its rotation leads to winding the remaining piece of fabric around the tipping.). surface of carrier 1. The location of the perforated section of the zipindric surface of the carrier relative to roller 9 is such that when the upper piece of fabric is wound around the carrier, then at least
    40
    45
    714719458
    the rear end of the piece of fabric is in contact with the perforated section of the cylindrical surface of the carrier.
    While a piece of fabric is smeared around the carrier element, a vacuum is created in chamber 11, under the action of which the piece of fabric is forcibly held in contact with the surface of the carrier element. Thus, at least two opposite ends of the piece of fabric are firmly held on the carrier element, i.e. one end is a roller 9, and the other is an image that can increase the end — a perforated section on the productivity of the device, the surface of a cylindrical carrier 1.
    As a result, the rolling motion along the guides of the carrier element 20 is in a position above the receiving base 12. The distance between the support 4 and the receiving base 12 is chosen such that when the carrier element rotates so that the rear end of the piece of fabric is at the lowest point on the supporting element, this end of the piece of fabric is clockwise to remove it from the gap and lay it on the surface 13 of the receiving base in a flat state.
     The carrier 1 now continues to rotate counterclockwise in order to return to the desired position above the stacker 6 in order to prepare for the seizure of the next piece of fabric that is the upper one in the stack 6.
