Definitions

  • the present invention relates to a device for attaching a thread to a workstation of a textile machine with a suction nozzle for picking up a thread end of the thread from a bobbin, the suction nozzle having a suction port, a suction channel and an inlet opening for the thread.
  • the device furthermore has a feed member arranged movably opposite the suction nozzle for forming a thread loop from the thread end picked up by the suction nozzle.
  • the feeder element has a cover element for closing the inlet opening of the suction nozzle and a thread guide element and is between a first position in which the thread guide element is located within the suction channel and the cover element closes the inlet opening of the suction nozzle, and a second position in which the thread guide element is located is located outside the suction channel and the cover element exposes the inlet opening of the suction nozzle, movable back and forth.
  • the DE 3 515 765 A1 shows a suction nozzle which is arranged in a movable maintenance device. After the thread has been successfully sucked in, the suction nozzle is removed a little from the bobbin surface so that the sucked-in thread is stretched between the suction nozzle and the bobbin is. Subsequently, a feeder element, which is also arranged in the movable maintenance device, is fed to the thread, which grabs the tensioned thread and transfers it to another handling element, forming a thread loop.
  • each of the work stations has its own suction nozzle.
  • Such a textile machine is in the EP 1 283 288 A2 described.
  • a pivotably mounted suction nozzle is provided at each of the workplaces, which picks up the thread from the bobbin surface in a first position and, after the thread end has been successfully sucked in, is pivoted into a second position in order to deliver the sucked-in thread end to other handling elements at the workstation.
  • the swiveling suction nozzle has a comparatively large space requirement and is structurally complex.
  • a textile machine with a workplace-specific suction nozzle which is fixedly arranged at the workplace, has also become known.
  • the stationary suction nozzle is assigned a movable feed element.
  • the feeder organ has a thread guide area which is already introduced into a suction channel of the suction nozzle before the thread end is sucked in, so that the thread end simultaneously enters the thread guide area of the feeder organ when it is sucked into the suction nozzle.
  • the feeder element can be pivoted in order to deliver the thread end to the further handling element while forming a thread loop.
  • the suction nozzle has an inlet opening for the thread guiding area of the feeder element and for leading the sucked thread out of the suction nozzle. During the search for the thread end on the bobbin surface, this inlet opening must be sealed.
  • the feeder organ has a cover element.
  • the object of the present invention is to propose a device for attaching a thread which enables a reliable sealing of the inlet opening of the suction nozzle during the thread search.
  • a device for attaching a thread to a work station of a textile machine has a suction nozzle for picking up a thread end of the thread from a bobbin, the suction nozzle having a suction port, a suction channel and an inlet opening for the thread. Furthermore, the device has a feeder element arranged movably opposite the suction nozzle for forming a thread loop from the thread end taken up by the suction nozzle, the feeder element having a cover element for closing the inlet opening of the suction nozzle and a thread guide element.
  • the feeder element is between a first position in which the thread guide element is located inside the suction channel and the cover element closes the inlet opening of the suction nozzle, and a second position in which the thread guide element is located outside the suction channel and the cover element releases the inlet opening of the suction nozzle and moveable.
  • the thread guide element has an open contour.
  • the cover element is only slightly stiffened by the thread guide element. This increases the flexibility of the cover element so that it can better adapt to the surface of the suction nozzle in the area of the inlet opening. In particular, the areas of the cover element which are not connected to the thread guide element can thereby adapt particularly well to the contour of the inlet opening and seal it off better. At the same time will Due to the open contour of the thread guide element, the flow inside the suction nozzle is less impaired, which supports the safe suction of the thread end and leads to reduced energy consumption. In addition, compared to a thread guide element with a closed contour, in particular when manufacturing the thread guide elements from a sheet metal material, a material saving can be achieved.
  • the cover element consists of a plastic material.
  • the cover element can be designed to be particularly flexible, so that it can also adapt particularly well to the contour of the suction nozzle and thus better seal the inlet opening.
  • the suction nozzle is made of a harder material than the cover element or the cover element is made of a softer material than the suction nozzle, so that solely due to the negative pressure prevailing in the suction nozzle, which draws the softer cover element towards the suction nozzle sealing can be improved.
  • the cover element is also bent in its longitudinal direction.
  • the longitudinal direction of the inlet opening is understood to mean the direction of the largest dimension of the inlet opening.
  • the longitudinal direction of the cover element is understood to mean the direction of the largest dimension of the cover element. Due to the curved contour, the sealing can be further improved, in particular in the area of the two longitudinal ends of the cover element or in the area of the two longitudinal ends of the inlet opening.
  • the inlet opening of the suction nozzle and the cover element each have at least one, preferably at least one each have two mutually opposite, beveled edges, which each form a sealing surface.
  • at least the two edges of the inlet opening and the cover element running in the longitudinal direction of the inlet opening are beveled, in the case of a rectangular inlet opening particularly preferably all four edges delimiting the inlet opening.
  • the cover element is provided with a sealing lip on its side facing the thread guide element, ie on the side facing the suction channel of the suction nozzle in the first position of the feeder element.
  • the sealing lip is preferably made from a flexible plastic material.
  • the sealing lip advantageously enables sealing even in the case of an uneven sealing gap between the suction nozzle and the cover element.
  • a silicone material or an elastomer material, for example, can be used as the flexible plastic material.
  • the cover element has at least one holding element, preferably several holding elements spaced apart from one another, on its side facing the thread guide element.
  • the sealing lip is only pushed onto the holding element or the holding elements. Because the sealing lip is only loosely attached, it is also slightly sucked in during the suction of the thread end by the negative pressure in the suction nozzle, which leads to an improved sealing effect. A self-sealing construction of the cover element is thus achieved.
  • the thread guide element is attached to the cover element off-center with respect to the longitudinal direction of the cover element, in particular on or in the region of a longitudinal end of the cover element.
  • the sealing in a central area of the cover element between the two longitudinal ends is hereby facilitated, in particular with a curved cover element and a curved contour of the suction nozzle.
  • the thread guide element consists of a sheet metal material, in particular a stainless steel sheet material or an aluminum sheet material.
  • the thread guide element can be produced in a particularly simple manner by punching or laser cutting.
  • the fiber guiding element is made entirely or partially (i.e. one or more sections of the fiber guiding element) from a ceramic material.
  • a ceramic material For example, it would be conceivable to manufacture the fiber guiding element or corresponding sections thereof by a 3D printing process and then to provide them with a ceramic layer by sintering.
  • the thread guide element is provided with a coating and / or is polished.
  • a thread guide element made of sheet aluminum material can be provided with an aluminum oxide layer, or a thread guide element made of sheet steel material can be provided with a DLC (diamond-like carbon) coating.
  • the thread guide element is provided with a friction-reducing coating. In this way, on the one hand, damage to the thread can be avoided. Furthermore, wear of the thread guide element can be counteracted by friction-reducing, but wear-resistant coatings. It is therefore also advantageous if the thread guide element is polished is. This also makes it possible to reduce the coefficient of friction of the thread guide element and thus also wear thereof.
  • the thread guide element has at least one first thread guide edge with a first fixing contour for a piece of thread to be removed and at least one second thread guide edge with a second fixing contour for a piece of thread to be attached.
