Definitions

  • the invention relates to a fabric laying machine for zigzag laying a fabric web with a fabric web guide, comprising a fabric web output guided at a predetermined height above a layer package made of fabric layers, from which the fabric web falls freely when laid and merges into the top fabric layer via a bend, as well as one of the fabric web output associated cutter.
  • Such a fabric laying machine is known from DE-A-32 18 484
  • the problem constantly arises that after laying out a fabric layer and cutting off the fabric web, due to an inherent curvature of the fabric web, both one end of the fabric layer laid out and one end of the fabric web still present in the fabric laying machine, in particular in the area of the The fabric dispenser bends, which leads to problems when it is newly created, since this causes the fabric web to curl or at least forms folds, so that the fabric layer package in the area of the edges running transversely to the laying direction does not show any precisely laid out fabric layers with overlapping cut edges, but at least wrinkled in this area designed and can therefore only be used to a limited extent for later processing.
  • the invention is therefore based on the object of improving a fabric laying machine of the type described at the outset in such a way that the fabric layers can be laid out precisely in the region of the edges of the layer package.
  • a fabric guiding surface which deflects the fabric web freely falling from the fabric web delivery is provided underneath the fabric web delivery and between the stack of layers and the web guiding surface can be moved in front of the fabric web delivery by a movement relative to the web delivery in the laying direction and opposite thereto.
  • the invention thus creates the possibility of deflecting a fabric web depending on the web output with a curved area adjoining the cut edges in such a way that the cut edge is congruent with the edge of the layer package on which it is to be applied, and / or an end of the uppermost layer of fabric that arises when the free-falling fabric web is cut off and that protrudes upward from the fabric layer package due to the inherent curvature.
  • a particularly effective way of designing the fabric web guide surface is that it deflects the freely falling fabric web in the opposite direction to the laying direction.
  • Such a fabric guide surface is used in particular to deflect one end of a fabric web still present in the fabric laying machine.
  • an embodiment of the fabric guiding surface is advantageous, in which the fabric guiding surface spreads out a freely falling end of the fabric layer in the laying direction.
  • the fabric guiding surface could be designed in the most varied of ways. For example, it would be possible to arrange the fabric web guide surface as a rotating part, which takes the fabric web hanging onto it by its rotation.
  • the fabric guiding surface can move on a wide variety of geometric paths in this area.
  • two fabric guiding surfaces are provided which deflect the freely falling fabric web in opposite directions.
  • either one or the other web guide surface can be brought into its effective position before the web delivery, so that when laying in one direction one web guide surface and when laying in the other direction the other web guide surface in Use is.
  • the two fabric web guide surfaces could in principle be provided on different machine parts. It would be possible, for example, to arrange each fabric guide surface on a bar, the bar in each case being brought into its effective position which has the corresponding fabric guide surface.
  • a solution is structurally simpler in which the fabric guiding surfaces are arranged on a fabric guiding element, so that this fabric guiding element only has to be movably arranged for changing from the effective position of one fabric guiding surface to the effective position of the other fabric guiding surface.
  • both fabric web guiding surfaces are arranged on a fabric web guiding element, these could for example be arranged relative to one another in such a way that they form a funnel leading to a funnel opening.
  • the fabric guiding element has fabric guiding surfaces which form a wedge surface with its tip facing the fabric web output, so that the two fabric guiding surfaces are thus arranged in a roof shape.
  • a further advantageous embodiment of the invention provides that the fabric guide element has fabric guide surfaces which deflect a free-falling end of the fabric web opposite to a laying direction with a partial area and spread a free-falling end of the uppermost fabric layer with another partial area when laying in the opposite laying direction.
  • the fabric guiding element can be moved with each guiding surface over the fabric web output, so that the mobility of the fabric guiding element has no effect on the travel paths of the fabric-laying machine according to the invention, but the fabric guiding element in the solution according to the invention independently a path required for deflecting the freely falling fabric can be moved.
  • the fabric guide element can be moved by a drive.
  • the fabric guide element should also be guided accordingly on the fabric laying machine.
  • the easiest way to solve this in terms of design is that the opposite ends of the fabric guide element are each slidably mounted on longitudinal guides.
  • the exemplary embodiments described above do not specify how the material web output itself should look like.
  • the material web output has a material web clamping device.
  • the jaws are designed as side parts of an inlet funnel in which the freely falling fabric can be inserted very easily .
  • control positions the fabric guide element in advance when laying out a bend in the fabric sheet.
  • the fabric guide element can be positioned so that it supports the bend with a fabric guide surface when laid out.
  • control positions the fabric guide element when it is applied to the edge of the layer package and restarting the fabric laying machine so that a front cut edge with a fabric guide surface is guided to an edge of the layer package, so that, despite a bend, the area of the fabric web adjoining the cut edge has no possibility of rolling up or wrinkling.
  • An additional possibility of using the fabric guide element according to the invention provides a control which positions it in such a way that it supports the fabric sheet during cutting, so that the fabric sheet cannot fall freely after the cut, but rests on the fabric guide element and then completely on it Layer package can be designed.
  • the advantage according to the invention can also be achieved in that the control positions the fabric guiding element in such a way that it follows the bending when laid out.
  • this arrangement of the fabric guiding element creates the possibility that the control moves the fabric guiding element in such a way that it passes under the fabric web when it is placed on the edge of the layer package, that is to say that initially the fabric web hangs freely from the fabric web output, due to the curvature of the fabric web is curved, and that the fabric guiding element then moves against this hanging fabric web and is moved so far that the fabric web is pulled over this fabric guiding element and thus bent and laid out in the direction of the edge of the layer package, so that the fabric web with its cutting edge is congruent on the edge of the layer package.
  • a control is useful which moves the fabric guide element in such a way that it spreads out the cut fabric sheet at the edge of the layer package.
  • This can also be achieved, in particular, with a fabric guide element arranged after the bend when laying, since this is only cut in after cutting Laying direction must be moved further and thereby has the possibility of completely spreading out the uppermost layer of fabric which projects upwards due to its curvature towards the edge of the layer package.
  • a first exemplary embodiment of a fabric laying machine according to the invention designated as a whole by 10, comprises a laying carriage 12 which can be moved in the laying direction 16 on a laying table 14.
  • a fabric web 24 is drawn off from a fabric roll 20 rotatably held on a top of the laying car 18 by means of a fabric web guide, designated as a whole as 22, and fed to a laying unit, designated as a whole as 26, according to a speed of the laying car 12 in the laying direction 16, which aggregate 24 defines the fabric web 24 as a single fabric layer comprehensive layer package 30 designs.
  • the fabric web guide 22 comprises a plurality of deflection rollers 32 to 40, via which the fabric web 24 is guided to a presetting roller 42, the presetting roller 42 being driven synchronously with the speed of the laying carriage 12.
  • the laying unit 26 is held in a height-displaceable manner on the laying carriage 12 and is always guided at a constant distance from the uppermost layer of fabric 28 of the layer package 30.
  • the laying unit 26 comprises two pivot plates 46 and 48 which are arranged symmetrically to a fold plane 44 defined by the fabric web 24 falling from the feed roller 42 and which extend across the entire web 24 and which are parallel to the Fall plane 44 and axes 52 and 54 running parallel to a layer plane 50 defined by the top fabric web 28 and arranged approximately in the middle of the pivot plate 46 and 48 from an open position oriented approximately parallel to the fall plane - shown in dashed lines in FIG. 2 - into a closed position - Drawn solid in Fig.
  • the swivel plates 46 and 48 are preferably provided with clamping jaws 60 and 62, respectively, with which the fabric web 24 can be clamped in the closed position of the swivel plates 46 and 48, in particular around the fabric web 24 below the clamping jaws 60 and 62 , cut off on the side facing the layer plane 50.
  • the pivot plates 46 and 48 are preferably mounted by means of stud bolts 66 and 68, which are arranged on a housing 64 of the laying unit coaxially with the axes 52 and 54 and which engage in bearing plates 70 and 72 held on the respective pivot plates 46 and 48.
  • Knife wheel 76 can be rotated about an axis 80 aligned parallel to the plane of the case 44 and perpendicular to the plane of the layer 50 and, with its outer sharpened circumferential area, reaches the fabric web 24 lying in the plane of the case 44 substantially immediately below the closed clamping jaws 60 and 62.
  • the entire cutting unit 74 can be moved along a rail 82 across the entire width of the fabric web 24 and beyond it, so that the cutting unit 74 can be positioned laterally outside the swivel plates 46 and 48 in the rest position.
  • the two swivel plates 46 and 48 also serve as a fabric web output when the fabric web 24 is placed, the fabric web 24 being swiveled down from the specification roller 42 down to the height of the jaws 60 by the swivel plates 46 and 48 or 62 is held in case level 44.
  • This is achieved by pivoting the front pivoting plate 46 or 48 in the laying direction 16 into its open position so that the bend 84, which runs in the form of a bend 84 opposite to the respective laying direction 16, passes from the fold plane 44 into the layer plane 50 bears on the clamping jaws 60 or 62 of the pivot plate 46 or 48, which is at the rear in the laying direction.
  • the laying unit 26 is guided on the laying carriage 12 such that the clamping jaws 60 and 62 are always at a constant height H above the layer plane 50 in their closed position.
  • a fabric web guide element 86 is provided in the manner according to the invention, which is both parallel to the case level 44 and at a constant distance A parallel to the layer plane 50 across the entire width of the fabric web 24 and also the width the pivot plates 46 and 48 extend in that direction.
  • This fabric guiding element 86 has two wedge-shaped fabric guiding surfaces 88 and 90, each oriented at the same angle of inclination to the plane 50, with a tip 92 of the wedge facing the clamping jaws 60 and 62, so that both fabric guiding surfaces 88 and 90 form inclined planes which the fabric web 24 can slide down in the direction of the layer plane 50 under the influence of gravity.
  • the fabric guide element 86 is made from a wedge-shaped bar.
  • This fabric web guide element 86 is now displaceable parallel to the layer plane 50 in the laying direction 16, so that it is dotted in FIG. 2 from a right extreme position lying in FIG. 2 to the right of the case level 44 - indicated by dash-dotted lines - into a left extreme position to the left of the case level 44 indicated - can be moved back and forth.
  • a guide bar 98 and 100 is held on both side walls 94 and 96 of the housing 64 of the laying unit 26, which run parallel to the laying direction 16 and which likewise runs parallel to the layer plane 50.

  • This layout to the left with the support of the fabric guide element 86 has the advantage that the extent and position of the bend is largely defined, so that the fabric web 24 can be laid out at a uniform speed in the top fabric layer 28 and there are no inaccuracies that would occur without that Fabric web guide element 86 could occur by varying the arc length of the bend 84.
  • the fabric web guide element is removed from it Move left laying position I, shown in dashed lines in FIG. 5, to its left cutting position II, in which tip 92 lies to the right of fall plane 44.
