    one
    The invention relates to the adaptation D | 1I of separating flexible flat materials, in particular, cut garments from piles.
    The aerodynamic effect is known for separation, for example, in DD-PS 72 208. using suction to remove the top flooring from the stack. The force arising from the suction depends on the material, in addition, there is the possibility of undesirable adherence of one or several underlying cut parts. Thus, the required functional reliability is not guaranteed.
    Other devices use a card, for example, DE-OS 1 760616. However, these devices do not prevent sticking of the cut parts of the stack from sticking, and the quick contamination of the surface of the adhering material of the card is not taken into account, which requires constant updating.
    In addition, needles, hooks, or needle bands are used as functional elements to separate parts from the stack. Using needle-like ribbons, for example in DD-PS 104 272 and 603 626, push the two risks that the functional elements are equipped with onto the upper cut-out part, then spread them out, causing the laid material to become tensioned, secured and can be removed. from the stack.
     A similar principle underlies US PS 2,160,437, where bba functional elements are made in the form of a rake with teeth bent upwards.
    A similar solution principle is found in DD-PS .. 116 192, DE-OS 2 002 750, DE-OS 3 407 941 and DE-OS 2 61I.; 739, where needle-like elements puncture the edges of the upper cut piece by rotating needles from the outside or top the part is pierced by a hooked needle that goes to the surface, and the part to be detached from the stack must also be tensioned.
    However, these solutions do not guarantee that subsequent downstream parts will not stick to the top. Therefore, for example in DE-OS 2 160 437, an auxiliary device is additionally used to separate the part from the stack. In addition, a hook-like needle can be used to pierce only on these materials. There is an undesirable gripping of the underlying parts.
    It is known from DE-OS 2 839 257 that the upper part is punctured with vertically set needles, and then it rises, however, there are disadvantages in the reliability of operation.

    DoDD-PS 123 732 tips directed outwardly along the needle are located around the circumference, which is located in the part separated from the stack. Finding the piece between the needles and the material is pressed, and the needles due to the deformation of this area of the material penetrate the cut piece, after which the separation process takes place with the lift.
    Since in this case it is possible to influence only narrowly limited the uppermost part, here too there is the possibility of undesirable adherence of the underlying parts, and it is necessary to take into account the complex construction of this type of design.
    5 It is known that the cut parts are captured only by points. Thus, according to DD-PS 108 708, two needles are attached on the rocking chair and, touching the surface of the material, as if form wrinkles on it, which upon subsequent
     needle crossings are pressed, and the tips of the needles describe the connecting curve, which in turn runs almost horizontally. However, there is no reliable separation of the part from the headquarters, since it is necessary to use an additional stream of compressed air from the nozzle. According to DE-OS 2 401 737, the workpiece is gripped by two clamping jaws, one of them having a thrash. the thorn tip, and the other, respectively, but a Y-shaped notch.
    These technical solutions guarantee reliable removal of parts from the stack, without using additional means to remove the adhering underlying parts of the stack, which leads to additional costs and affects the design of the stack or changes in the shape and position of the parts.
    The aim of the invention is to separate the upper part from the stack of mechanical
    in a manner with minimal technical costs and without additional aids, ensuring reliable separation of each upper cut piece from the stack without affecting the shape and its position, while ensuring automation of the process and, if necessary, automatic processing of the cut pieces of clothing separated from the stack.
    The invention is based on the task
    0 by means of a technically simple device with the aim of overcoming the adhesion force to perform the relative movement of the cut-out part detachable from the stack relative to the underlying part over the entire surface of the material, then remove
    S top part with a stack with the whole plane.
    This is achieved by means of a device in which a connecting element is unwound under a vertical lifting mechanism in a longitudinal section of the shaft. This connecting element may consist of one or several parts. Each end of the connecting element is connected with transversely arranged fixed needle strips, the needle strips along the entire length are equipped with needles, which are directed downwards, but at a large distance but two guides, and with their help, through each drive element. movable needle pin, which is also equipped with downwardly located needles pointing down. These needles, together with each adjacent needle of the fixed needle strip, form an acute angle, and on the movable needle strip there are two shaped-convex groove holes where the guides of the fixed needle strip enter. On the fixed needle strips by means of spacers under both the movable and fixed needle strips, which form the jumper, a pressure plate is attached, having a slotted screw-in. sticks, through which the needles of the fixed bar pass, the tips of which are slightly visible on the back side. In this case, the needles are arranged so that the I1s of the moving bar are at a greater angle than the fixed one.
    The needles of each needle bar are located along one vertical straight line, which corresponds to the longitudinal direction of the needle bar, but they can also be located at an angle in the transverse direction, and in this case the tips of the needles have a longitudinal direction.
    In order to separate the part, the proposed tool is lowered onto the stack by means of a lifting mechanism, with the needles of the fixed needle strip touching the upper part of the surface and fixed in this position. As a result of driving the drive elements, the movable needle strips set in motion and then fall into the longitudinal holes of the corresponding guide and take their final position at the point of the convex groove curve, thus forming a fold on the material.
    Continuing the movement of the needle, the movable needle bar is raised again, and they move towards the tips of the needles of the fixed needle bar, increasing the fold. As a result of the operation of the lifting mechanism, as well as the drive element, the device rises and, as a result of pushing both needle beds, the raised parts are pulled in the transverse direction. As a result, the parts to be separated are reliably interlocked also by C11nmak:) but planes.
    In need of the remaining forces prilig ani inter. loga.h mi completely overcome the tension by 1e 1 st tension. With the new actuation and olfinTHbiM movement of the driving elements of the moving needle pins, the latter return to their original position, which allows the separated part 1 (d) to be placed in the corresponding position of the processing card.
    The effect of section1P1 is based on the fact that the capture of its full detail relative movement doesn’t like the adhesion forces of the underlying detail; 1i.
    This is due to the fact that during the formation of a fold due to the movement of the movable needle bar, when the material is fixed by the needles of the fixed needle bar, an assembly (within the fold formation) and stretch (between the folds) in two longitudinal directions are caused, and at each point a relative movement occurs .
    All known devices for separating parts can capture separated parts only at the edges and as a result, the material is stretched across the entire surface of the part, which is not achieved in the middle of the part, since not all materials are quite flexible. Despite stretching in the middle of the part, relative movement does not occur with respect to the underlying part. Therefore, existing sticking forces are maintained, which inevitably leads to the adhesion of the underlying part to the upper part, with the result that the separation effect is not guaranteed to vaporize this method on automatic flow lines.
    The proposed design allows dense rows of paired needles of both play sticks to be placed, as a result of which relative movement is also achieved with materials that have a weak elastic stretch. The residual force in the middle of the part is eliminated by the subsequent stretching of the part in the transverse direction.
    When separating parts of large size in order to improve stability, it is advisable to use two connecting elements. In addition, one more third needle bed can be added, which should be under the lifting mechanism and in the center of the connecting element. This ensures relative movement in the center of the large part. The position occupied by the middle needle bar during the movement of the connecting elements is not changed, both side needles being removed, as a result of which the part is stretched between the central and side needles.
    For very small narrow parts, the device for separating parts is equipped with only one needle bed, which must be located indirectly by a node with an iodine mechanism.
    On fis. 1 and: the device is in working position, front view; in fig. 2 - one needle bar in an average working position, side view; (() Hf. 3 is a device in plan view; and Fig. 4 is a picture of the movement of needles.
    FIG. 3 depicts the “11” 1 | e elements only above the n) needle bed.
    A single, removable mechanism 1 in the form of a pneumatic cylinder with air ducts 2 a, b through bridge 3 is tically connected with a two-member horizontal connecting element 4.
    The connecting element 4 has one segment 4 a and b, which by means of the driving element 5 in the form of a pneumatic cylinder with air ducts 6 a, b are interconnected so that the connecting element 4 can be lengthened (working position) and shortened again (the initial position ).
    Each of the connecting elements 4 a and b is firmly connected to the side with the inner fixed needle bar 7 of one needle bed, which has needles 8 over its entire length. To the inner fixed needle bar 7, one contoured piece 9 is attached to it, in which as a drive element 10 mounted movably in one pneumatic cylinder with air ducts 1 a, b, which through the fittings 12 are movably connected to each movable outer needle needle bar 13, equipped with evenly spaced needles along its entire length 14 s.
    The needles 8 and 14 are attached to the corresponding needle bars 7 and 13 in such a way that their tips are facing each other, and for this design example, needles 14 are more inclined (at a greater angle) than needles 8, both types of needles stand on the same vertical.
    BneiHHue movable needle-like nlanks 13 have, however, two longitudinal orifices 15 formed along with a convex curve, into which enter one guiding element 16 fitted as an adjusting stud, which are attached to the inner fixed needle-strips 7, besides, they are fastened vertically spacers 17, at one end of which there is a horizontal pressure plate 18 having slots 19, at which needles 8 and 14 engage.
    The detachable connection of the spacers 17 allows the pressure plate 18 to be rearranged upward so that the adaptation of the part separation can be adjusted to different material thicknesses or to separate
    details, betraying the working city of needles 8 and 14.-.
    The start-up of the device, by operating (imitating) 1 fur (ism 1, two-membered connecting element 4 together with needle cases is lowered until the knock of the press plate 18 does not touch the upper cutting part 20 1 the cable, and d1 () Dim is equal to the sum of the height Guitabel and heights
     lifting the detachable part.
    With the help of a push-button contactor or a time relay of the lidding mechanism I, the potential difference in height of the stack and pressure plate 18 is evened out.
    2 as a clamping force limiter. Thus, it is achieved that even after repeatedly separating the part, there is no need to lift the table with the stack of cut parts (not shown) and, despite this, for each separable
    0 parts have the same initial conditions (e.g. clamping force).
    The needles 8 of the inner fixed needle bar 7 are mounted so that they
    - just slightly impose the upper part 20 of the stack through the slots 19 of the pressure plate 18, as a result of which they fix the part at this place. The needles 14 of the outer movable needle bar 13 are mounted so that in their initial position
    0 they had the level of the bottom edge of the G8 pressure plate.
    The actuation of the drive elements 10 in accordance with the convex curve of the longitudinal holes drives the outer needle bars 13,
    5, as a result of which the needles 14 descend and describe the movement curve 22, reaching its highest point at the moment of the peak of the longitudinal mortise hole.
    When this needle 14 captures the top
    d detail 20, slightly piercing the surface of the latter, and form one fold 23 on it. As the external needle-like strips 13 move along to the end of the longitudinal holes 15, the needles 14, in accordance with the movement curve 22, rise again, and
    5, the folds increase, and the tips of the needles 8 and 14 reach their closest approximation.
    At the same time, the upper part 20 itself in the zone of the formed crease, and, ki is collected and a part of the material between the individual folds 23 is tensioned, as a result of which the relative movement of the upper part 20 relative to the area of the remaining cut parts of the stack 21 in this area of material.
    5 Now the drive elements 1 and 5 are activated, the device is raised again, and at the same time due to the resulting elongation of the connecting element 4, the distance between the legs is increased, with the result that the piece 20 nt also bend in the transverse section on the nip type. Due to this, the transiently directed relative movement doesn’t change the last osg; the force of adhesion of the underlying parts (ntlbells, and the part 20 is reliably removed. The removed part can be left unchanged as needed by the iioc.ie.ay.ayKinirii treatment and the new CPG) (-m of the NN elements) And the needles of the strip 13 are returned to the demolition of the initial position and the part 20 is released.
    It is recognized as an invention but the results of the examination, the foundations, by the Office for the invention of the German Democratic Republic.
