Definitions

  • the invention relates to a fabric laying machine for applying layers of fabric to a cutting table with a horizontally movable carriage and an unwinding station in which there is a bale formed from a rolled-up fabric web, which is set in rotation by means of two synchronously driven wheels, the Bale of fabric rests on the wheels in its lower area.
  • a fabric laying machine of the generic type is known. Its basic structure consists of two horizontal cylinders mounted on a carriage and arranged parallel to each other, which rotate synchronously be transferred. Since the lower area of the rolled-up fabric bale rests on the cylinders, it is also rotated so that a fabric web is unwound. It is then laterally deflected by one of the cylinders and usually another roller and leaves the carriage laterally next to the axis of the fabric bale.
  • a disadvantage is that, especially in the case of an almost unwrapped bale of fabric, the non-positive connection to the rollers is impaired by slippage due to the low pressure force, so that the fabric is not unwound at the same speed at all times and a uniform, tension-free placement on the cutting table is not guaranteed .
  • EP-A 0 200 604 describes a fabric laying machine in which a mobile carriage is fastened to a cutting table and carries the horizontally running axis of a bale of fabric which is rotatably mounted on the end face.
  • the bale is pressed against the bearing on the carriage by a belt which is driven by two wheels with parallel axes arranged vertically one above the other and set in rotation in such a way that the material is unrolled, sinks vertically downwards by gravity and lies down on the cutting table during a horizontal movement of the carriage.
  • the wheels are firmly attached to the carriage, while the bale of fabric is reduced by a diameter due to its unwinding Cylinder laterally shifted and pressed against the belt.
  • this fabric-laying machine in addition to the cost-intensive cylinder for lateral displacement of the fabric bale, it is to be regarded as disadvantageous that the front-side storage requires a not inconsiderable effort when changing the fabric bale.
  • the invention has taken on the task of further developing the fabric laying machines of the generic type in such a way that the fabric web can be applied to the cutting table without tension and in particular also in several layers.
  • the object is achieved in that the circumference of the fabric bale is detected from above by rollers located on swivel arms and that the fabric web unwound from the fabric bale separates directly in the vertical direction downward from the carriage and leaves the carriage below the axis of the fabric bale.
  • the main idea of the invention is that after unwinding, the fabric is moved immediately, ie without deflection on driven transport rollers and only under the influence of gravity in the vertical direction down to the cutting table and deposited there due to the horizontal movement of the carriage.
  • the handling takes place solely by rotating the fabric bales and without pulling the fabric web (with the exception of gravity) in the direction of movement. It hits the cutting table at a right angle.
  • the fabric bale is gripped and unwound by means of driven wheels acting on its circumference. Their peripheral speed corresponds exactly to the translational speed of the fabric web currently being processed. The radius or its change are then meaningless.
  • Another advantage of this embodiment is that the change of the bales of fabric can be carried out much faster, since none Frontal engagement of claws in the fabric bale and no more engagement is necessary. The bale is now still scissor-like.
  • the bale of fabric lies on the two driven wheels in the lower area and is gripped from above, also on the circumference, by rollers located on swivel arms.
  • the fabric web is guided past a cutting device immediately before leaving the laying machine.
  • a cutting device immediately before leaving the laying machine.
  • the intended length of the fabric is reached, it can be cut off without interrupting the translatory movement of the carriage.
  • the known fabric laying machines cut the fabric in the laid-on state, so that the machine has to go beyond the cutting line and later have to move back again.
  • An embodiment with a clamping device before and / or after the cutting device is preferred, by means of which the fabric web can be spatially fixed during the cutting process. Otherwise, when using elastic fabrics - this includes e.g. Jersey, stretch fabric - due to the tension occurring during the cutting process, cut inaccuracies result.
  • the device according to the invention allows work without the use of a catcher.
  • the head of the unwinding station be folded up so that a direct grasping of the bales of material presented in a magazine is possible by opening the wheels attacking the circumference. In this way, a quick change can be implemented.
  • an optical sensor for detecting the edge of the fabric is provided, by means of which the markings located there can be detected.
  • the machine then automatically recognizes the weaving errors and can be controlled in a way that avoids corresponding quality defects in the finished product. This saves the surveillance person who is customary in the prior art and serves to control the quality of the fabric that is laid.
  • the carriage (1) represents a frame-like construction which on its underside can be moved horizontally on wheels (3) on rails (4) which are attached laterally on the edge of a cutting table (not shown).
  • the carriage (1) serves to support the unwinding station (2), to shift it horizontally and to create a space between the cutting table and the unwinding station (2) in which the individual layers of fabric can be successively placed on top of one another.
  • the unwinding station (2) consists of a foot (5) resting on the carriage (1) from above as well as a head (7) which adjoins upwards via a folding axis (6) running perpendicular to the plane of the drawing and which thus pivots to the left can be.
  • the bale of fabric (10) lies in the lower area on two driven wheels (11) and is by above, also on the circumference, of rollers (13) located on swivel arms (12).
  • the swivel arms (12) move towards the center of the fabric bale (10) and are opened in the manner indicated when the fabric bale (10) is replaced.
  • the fabric web unwound from the fabric bale (10) which first runs over part of the circumference of one of the wheels (11) and then in the vertical direction down to the cutting table located at the level of the running rail (4) and not recognizable here emotional.
  • the wheels (11) are connected to a drive (14) via belts.
  • the task of the turntable (8) is to create the possibility of pairing the pivoting of the fabric bale (10) located in the unwinding station (2) by 180 degrees around a pivot axis running in the plane of the drawing.
