Definitions

  • the present invention relates to a warping device with a warping drum, a thread sheet feed path and a cross-laying device, which has a shedding device in the thread sheet feed path and a cross-cord insertion device with which a cross-cord can be inserted into a compartment formed by a divided thread sheet, wherein a first cross-cord joining device is arranged laterally next to the thread sheet path on one side.
  • the present invention relates to a method for producing a crosshair in a sheet of thread that is wound onto a warping drum, in which a first compartment is formed by dividing the sheet of thread, a first cross cord is inserted into the first compartment by a cross cord insertion device, a second compartment is formed by dividing the sheet of thread, a second cross cord is inserted into the second compartment by the cross cord insertion device, and the cross cords are connected to one another next to the sheet of thread.
  • Such a warping device and such a method are known from EP 1 143 052 A1 known.
  • An insertion element which has two guide arms, is moved with one end through a compartment and connected to the other guide arm on the other side of the thread sheet.
  • a cross cord can then be sucked through the two guide arms so that a loop of the cross cord is formed around part of the thread sheet.
  • the ends of the loop are then connected to one another by a knotting device.
  • a thread sheet When warping threads into a warp, a thread sheet is usually formed by pulling a certain number of threads simultaneously from spools arranged in a creel. These threads are guided through a reed and, if necessary, further reeds and are thereby wound in a certain The threads arranged in this way are wound onto the warping drum. At predetermined intervals, usually every 500 to 2000 m along the length of the thread sheet, a cross hair is inserted into the thread sheet. To do this, a first compartment is formed by, for example, lifting every second thread of the thread sheet so that the alternating threads lying next to each other are a certain distance apart in a direction perpendicular to the thread sheet. A cross cord is inserted into this first compartment.
  • a second compartment is then formed by lifting the threads that were not previously lifted, while the previously lifted threads are left in their unlifted position.
  • a cross cord is again inserted into this second compartment. The two cross cords are connected to one another in order to fix the threads in the thread sheet against one another.
  • the warping drum When creating the crosshairs, the warping drum must be stopped. The warping process must be interrupted. The time needed to create the crosshairs is not available for winding, i.e. the actual creation of the warp.
  • the invention is based on the object of enabling a high productivity of the warping machine.
  • This object is achieved in a warping device of the type mentioned above in that a second cross-cord joining device is arranged on the opposite side of the thread sheet path.
  • the cross cord joining device can automate the joining of the cross cords after they have been inserted, so that the entire creation of the cross hairs in the thread sheet can be automated.
  • the cross cord or cross cords are automatically inserted into the compartments in the thread sheet and, after they have been guided through the thread sheet, are also automatically joined together. It is therefore no longer necessary for an operator to be available to carry out the joining.
  • the cross cord joining device is designed as a cross cord knotting device.
  • the cross cord knotting device can knot the cross cords together so that a reliable connection can be created between the cross cords.
  • a position of the cross-cord joining device can be adjusted in a direction perpendicular to a thread sheet running direction in the thread sheet path.
  • the position of the cross-cord joining device can therefore be adapted to the width of the thread sheet. This allows the consumption of the material used for the cross-cord to be kept low.
  • the cross-cord only needs to be made slightly longer than the width of the thread sheet.
  • the cross-cord joining device can be positioned using a thread edge detection device. This also allows the positioning of the cross-cord joining device to be automated. Adjustment work can be carried out quickly and, above all, precisely.
  • the cross-cord insertion device has a first gripper that can be inserted into the compartment from a first side, and a second gripper that can be inserted into the compartment from a second side opposite the first side.
  • the cross cord insertion device can have a blowing device and/or a suction device.
  • the cross cord can then be transported through the compartment with the aid of air.
  • a cross cord holding device is arranged on at least one side of the thread sheet path, which has two clamping devices on a carrier which can be rotated about an axis which is arranged between these clamping devices.
  • the operation of such a cross cord holding device can be described, for example, as follows: a cross cord is pulled from a spool and inserted into the two clamping devices. The section of the cross cord located between the two clamping devices is then acted upon to insert the cross cord into the compartment. In the first half of the movement, the clamping device adjacent to the spool is released. The other clamping device is held in place.
  • the clamping device arranged adjacent to the spool is activated and then holds the cross cord while the other clamping device is released so that the free end of the cross cord can be guided through the compartment.
  • the cross cord As soon as the cross cord has been guided through the thread sheet, it is severed on the side of the clamping device facing away from the spool. If the carrier is then turned by 180°, the starting position described above is restored. The holding of the cross cord can then also be automated.
  • the position of the cross cord holding device is adjustable in a direction perpendicular to a thread sheet running direction in the thread sheet path.
  • the cross cord holding device can then also be adjusted to the width of the thread sheet.
  • the cross cord knotting device has a thread gripper which can be rotated around a sleeve and which acts on the end sections of the cross cord to be knotted, the sleeve having a longitudinal slot and a suction pipe arranged in the sleeve which creates a negative pressure in the region of the longitudinal slot. and which can be moved.
  • the thread gripper guides the ends of the two cross cords to be knotted around the sleeve.
  • the suction tube sucks these ends through the longitudinal slot and, as the suction tube moves, it pulls these ends through the loop that has been formed around the sleeve. This creates a knot.
  • the warping drum is connected to a control device that also controls the cross-laying device, whereby the control device stops the warping drum at different angular positions during different cross-cord insertion processes.
  • a control device that also controls the cross-laying device, whereby the control device stops the warping drum at different angular positions during different cross-cord insertion processes.
  • This avoids accumulations of cross-cords on the winding drum at integer multiples of a wrap angle of 360°. Such accumulations would, for example, lead to increased imbalance and thus impair the winding speed. This also helps to keep productivity high.
  • the invention is also achieved by a method of the type mentioned at the outset in that the cross cords are connected to one another by a first cross cord joining device on one side of the thread group and by a second cross cord joining device on the opposite side of the thread group.
  • a cross cord knotting device is used as the cross cord joining device. This allows the connection between the cross cords to be made as a knot. A knot is a reliable connection.
  • one position of the cross cord joining device is adapted to the width of the thread sheet. This keeps the consumption of material used for the cross cords to a minimum, which has a positive effect on costs.
  • a thread sheet edge is detected by a thread sheet edge detection device and the position of the cross cord joining device is set based on an output signal from the thread sheet edge detection device.
  • the adjustment of the cross cord joining device to the corresponding width of the thread sheet can also be automated in this way.
  • the warping drum is stopped at different angular positions to create crosshairs. This avoids accumulations of crosshairs on the warping drum at integer multiples of a wrap angle of 360°.
