Definitions

  • the present invention relates to a device for handling harness elements such as a drawing-in machine and a method for handling harness elements.
  • a drawing-in machine is understood to be a machine for drawing threads or warp threads into harness elements, which can be divided into various functional units and has corresponding devices and sub-devices. These are, for example, devices for providing strands and lamellas into which threads are to be drawn. In these provisioning devices, the harness elements are suspended from one another on rail-like guides, as is generally the case, for example, also in their distribution or in weaving. Furthermore, a device for holding a reed is required "on the input side". As a central device, a drawing-in machine has a drawing-in device that guides threads, for example, through reed, heddle, lamella and through components of a crosshair.
  • the pulled-in lamellas and strands must be removed from the vicinity of the pull-in device on the "dismantling side" in order to prevent backflow.
  • strands and lamellas are mainly transported quickly over short distances in order to achieve a high number of cycles when pulling in.
  • the harness elements After being pulled in, the harness elements must be pushed over mostly long rail-like guides. This removal takes place at a predominantly slow speed, but relatively long distances have to be covered for the harness elements. This is typically 2 to 3 m, but sometimes up to 6 m is required.
  • lamellae and strands have to be transported away in parallel in devices arranged next to one another.
  • the present invention is primarily concerned with the transport of the harness elements from a supply device via the pull-in device to the receiving device.
  • the invention is advantageously concerned with a module for transporting stranded wires, but lamellae are not excluded.
  • the DE69008100T2 describes a drawing-in machine that guides strands on track-shaped rails and transports and positions them using various pushers or slides.
  • a selection for the transport direction for pushing the harness element onto a predetermined heald frame is optionally made by means of a rotatable rail.
  • a plunger is guided along the rotatable rail by means of complex guides, which are subject to high wear.
  • the WO9205303A1 discloses a drawing-in machine in which numerous holding means for stranded wires are mounted on a carrier at regular intervals. After being separated, a strand remains on the same holding means until it is pulled in until it is pushed off. This procedure is intended to increase the reliability of the drawing-in machine and to enable a modular structure. Each rail on which a strand could be repelled is assigned an individually controlled actuator for pushing off.
  • the object of the present invention is to provide a device for handling harness elements and a method for handling harness elements which offers the highest possible reliability and yet a simple structure when handling the harness elements.
  • the device according to the invention for handling harness elements has a first holding element.
  • the first holding element is designed to be moved cyclically between a supply device and a receiving device.
  • the first holding element is arranged on a carrier device.
  • a repelling element for repelling a harness element from the holding element onto a sub-device of the receiving device is also arranged on the carrier device.
  • the first holding element is preferably set up to carry out its cyclical movement in a plane on which an axis is perpendicular.
  • the repelling element By integrating a repelling element in a carrier device of a holding element, the repelling element can throw off a harness element arranged on the holding element with high reliability. At the same time, the integration enables a simple construction of the device with a small number of actuators to be switched.
  • the holding element can be designed in the shape of a pin or a rod.
  • the holding element can be designed to be inserted into an end eyelet of a harness element, in particular a Braid to intervene.
  • the holding element can have a longitudinal extension which is at least sufficient to be able to securely receive a harness element while observing all tolerances.
  • the holding element can consist of a steel in order not to wear out quickly through contact with the harness elements.
  • a provision device can have one or more rail-like sub-devices in order to provide harness elements for their collection.
  • the provision device can have one or more compartment devices for separating woven harness elements.
  • the provision device can be a partial device of a strand module.
  • a carrier device can serve, among other things, to initiate the movement of the holding element in that the carrier device is operatively connected to an actuator.
  • the carrier device can advantageously be arranged to be rotatable about an axis.
  • the trajectory of the cyclical movement of the first holding element can follow a circular path that encloses a circular area and an axis can be determined by the perpendicular to the circular area.
  • the carrier device can be driven by an electric motor. In the case of several carrier devices, each carrier device can be assigned a separate electric motor.
  • the repelling element can be arranged so as to be movable relative to the carrier device by a mechanical actuator arranged on the carrier device.
  • the repelling element can comprise a biasing element which is arranged such that the repelling element can be displaced by means of the biasing element from a stationary device element in relation to the carrier device into a retracted position when the carrier device is moved past the fixed device element.
  • a mechanical tension is built up in the mechanical actuator when the carrier device is moved past the stationary device element.
  • the repelling element can comprise a mechanical actuator which is formed by a spring.
  • the spring can, for example, be pretensioned relative to the stationary device element by the movements of the carrier device which are necessary anyway.
  • the repelling element can be arranged on the carrier device such that it can be locked in a retracted position.
  • the repelling element is preferably automatically locked during pretensioning, for example by means of a mechanical form fit which engages when the repelling element reaches its retracted position.
  • the fixed device element can preferably be a contact surface for a prestressing element of the carrier device, the distance of which increases or decreases with respect to a common axis, in order to deflect the prestressing element in the radial direction when it moves past and thus a mechanical actuator , preferably a tension spring or a compression spring.
  • the prestressing element can be made in one piece with the repelling element or can be arranged immovably on the repelling element.
  • the carrier device can have an unlocking element which is set up in such a way that when the unlocking element is displaced relative to the carrier device, the push-off element is unlocked and can perform a push-off movement driven by the mechanical actuator.
  • the unlocking element is preferably arranged on the carrier device, pretensioned by a spring, in order to automatically lock the repelling element by means of a form fit when the repelling element is driven into a retracted position by the pretensioning element.
  • An unlocking device element can be arranged in such a way that the displacement of the unlocking element of the carrier device can be provided by the unlocking device element which is arranged to be movable in the direction of the axis relative to the carrier device.
  • the unlocking device element can furthermore be set up in such a way that the unlocking element of a carrier device which is arranged on any partial device of the receiving device can be displaced.
  • a form fit that has come about during pretensioning is canceled and the repelling element is thus unlocked and driven out by the tension in the mechanical actuator.
  • the unlocking device element is advantageously simultaneously effective for carrier devices that are arranged on any part of a handling device such as the receiving device, which in turn keeps the number of components small and thus promotes economy and reliability. In the case of carrier devices rotating about a common axis, this can be set up in such a way that the unlocking device element has an angular extent in the direction of rotation of the carrier device so that an unlocking element of a carrier device can be detected at any possible angular position of the carrier device.
  • Such an unlocking device element can extend in an arc shape and in particular in a circular arc shape.
  • Such an unlocking device element can in relation act on an axis at a radial distance which corresponds to the radial distance of the unlocking element from a center of rotation of the carrier device.
  • the unlocking device element preferably acts in a direction parallel to the axis.
  • the unlocking device element acts preferably on the carrier device from the side which is opposite to the direction of a harness element held on the carrier device.
  • a stop element can be arranged on the carrier device, which is directed in the opposite direction to the repelling movement of the repelling element in the area of its extended end position.
  • the stop element is also set up to be able to push back the push-off element from the extended end position of its push-off movement.
  • the stop element can prevent the repelling element from coming back into contact with harness elements that have already been repelled. In this way, the reliability can be increased again.
  • a spring can preferably be assigned to the stop element, which spring is compressed by the impacting repelling element and displaced back from its end position by a force driven by the spring.
  • the repulsion element can be displaced back from its end position by a maximum of 10% or 20% of its distance of the repulsion movement.
  • a supplementary holding element can be assigned to the first holding element at a distance along the axis.
  • the first holding element and / or the supplementary holding element can be movably arranged on a carrier device in order to be able to hold a harness element under tensile stress between the first holding element and the supplementary holding element. In this way, disruptive movements of the harness element between the holding elements are at least partially suppressed and the reliability of the device is increased.
  • Said axial distance is adjustable and can be adapted to the length of a harness element.
  • a movable holding element is preferably arranged on a carrier device in such a way that the harness element is pretensioned when no external force is applied.
  • a relaxation device element can preferably be arranged on the device in order to be able to act on the supplementary holding element or a relaxation pressure element assigned to the holding element with a displacement.
  • the shift is preferably parallel to the direction of the axis.
  • a supplementary holding element movably arranged on the carrier device can be arranged on the carrier device so as to be pivotable about a bearing axis of the holding element.
  • the relaxation device element like the unlocking device element, can have an angular extent, so that a holding element on each sub-device of the receiving device can be subjected to a displacement.
  • An additional, equal-acting expansion device element can also be assigned to the supply device.
  • the relaxation device element and the unlocking device element can be formed in one piece on the receiving device, which in turn reduces the number of parts and increases reliability. In any case, the relaxation device element preferably acts before the unlocking device element.
  • the device according to the invention can in particular be a module such as a stranded wire module of a modular drawing-in machine.
  • the module can preferably be separated mechanically as well as electrically from the drawing-in machine without the function of other modules being impaired.
  • the module can perform its functions when other modules are deactivated or even dismantled.
  • the supply device of the strand module can have one or more sub-devices at which the holding element can take over a strand from a supply.
  • the holding element can move a harness element such as a heald to various handling devices. This can be a retraction device, a measuring device, a marking device, an ejection device, a receiving device or others.
  • a pull-in device can be used to pull a yarn into a thread eye of a strand.
  • strands can be classified according to their quality and, if necessary, labeled accordingly (labeling device) or sorted out (ejection device).
  • labeling device labeled accordingly
  • ejection device ejection device
  • strands into which a yarn has been drawn are repelled onto one of mostly several individual sub-devices of a receiving device.

  • the receiving device can be a partial device of a drawing-in machine.
  • the receiving device can be a partial device of a crockery cart.
  • a first holding element moves cyclically between a supply device and a receiving device.
  • the first holding element leads his cyclic movement in a plane on which one axis is perpendicular.
  • the first holding element is arranged on a carrier device.
  • a repelling element which is also arranged on the carrier device pushes a harness element which is arranged on the holding element onto a partial device of the receiving device.
  • the simultaneous movement of the holding element with the harness element and the push-off element enables a particularly reliable push-off of the harness element with a particularly simple structure that comprises few parts that can be controlled.
  • a push-off cannot fail because the holding means does not correctly position the harness element in front of a push-off element assigned to a partial device of a receiving device or because a corresponding push-off element is not correctly activated.
  • the first holding element preferably moves on a circular path which encloses a circular area and an axis is determined by the perpendicular to the circular area.
  • the carrier device of the first holding element can move past a stationary device element in order to displace the repelling element relative to the carrier device.
  • An unlocking device element can move in the direction of the axis relative to the carrier device arranged on a partial device of the receiving device and move an unlocking element arranged on the carrier device relative to the carrier device, so that the push-off element moves a harness element arranged on the holding element onto a partial device of the Receiving device repels.
