Definitions

  • the invention relates to a splicing head for a splicing device, a splicing device with at least one splicing head, a method for splicing yarn with a splicing head and a computer program product.
  • Splicing devices are commonly used to join threads, yarn or similar materials.
  • compressed air splicing devices compressed air is applied to the yarn, in particular to the ends of the yarn, in order to swirl them, as a result of which the filaments of the yarns open and intertwine with one another. This makes it easy to connect yarns. For a clean connection between the yarns, it is particularly important that the yarn ends are spliced well, otherwise they could get caught in eyelets.
  • the object of the invention is to eliminate these and other disadvantages of the prior art and, in particular, to provide a splice head, a splicing device with splice heads and a computer program product which ensure that yarn ends are well integrated by the splicing process.
  • a splice head for a splicing device for a splicing device, a splicing device with at least one splice head, a method for splicing yarn with a splice head and a computer program product according to the independent claims.
  • a splice head for a splicing device comprising a splicing chamber and a clamping device for clamping yarns.
  • the clamping device is arranged between two sections of the splice chamber.
  • the clamping device is arranged on the splice head so that it can be operated independently, so that the clamping device can be operated before or after the splice chamber is closed.
  • the splice head comprises at least one pull-in element to ensure that the yarn ends are arranged in the splice chamber, in particular for pulling the yarn ends into the splice chamber.
  • a problem with being able to splice the yarn ends well is that the yarn ends after being cut are often a little longer or about the same length as the splice chamber and are therefore not arranged entirely in the splice chamber. They are not sufficiently exposed to the splicing medium, for example compressed air or water jets.
  • the draw-in element can ensure that the yarn ends are drawn in and that they are completely in the splice chamber after readjustment. This makes it easier to splice the yarn ends.
  • the draw-in element is preferably designed such that the distance from an entrance of the yarn into a splicing chamber to a clamping element of a clamping device is lengthened and / or can be lengthened. This can be achieved in particular by guiding the yarn over a surface or over a body or by moving or extending the splice chamber in the direction of the entrance for the yarn.
  • the draw-in element can be movable in the splice chamber so that the yarn can be brought into a curved configuration by impinging on a surface of the element element and thus has a longer path from the entrance of the yarn to the clamping element.
  • the splice chamber can be displaceable.
  • at least one cutting element can be arranged within a splice chamber, preferably in a splice chamber section, in particular in a wall of a splice chamber or a splice chamber section.
  • the splice chamber can be designed to be extendable and / or displaceable, in particular the splice chamber can comprise splice chamber sections, the splice chamber sections being displaceable in the thread guiding direction so that at least one end of the yarn is completely in the splice chamber section.
  • the thread feed direction is the direction along which the thread is fed into the splice head.
  • the splice head preferably comprises further, in particular two further, clamping devices.
  • the clamping devices are preferably arranged upstream and downstream of the splice chamber sections in the thread guiding direction.
  • at least one of the further clamping devices is pivotably and / or displaceably arranged on the splice head, preferably displaceable in the thread guiding direction, particularly preferably the draw-in device is part of the further clamping devices.
  • the clamping devices can be designed so that only one yarn can be clamped individually or both individually and / or both can be clamped together.
  • the clamping devices can each comprise at least two, preferably three, clamping elements.
  • the clamping device can comprise two single-sided clamping elements and one versatile clamping element.
  • a one-sided clamping element has a single clamping surface.
  • a versatile clamping element has more than one clamping surface.
  • the one-sided clamping elements can be arranged on the splice head in such a way that they enable clamping with one surface of a versatile clamping element each.
  • the at least one pull-in element can be part of the clamping device and / or at least one pull-in element can be an element that is independent of the clamping device. If at least one pull-in element is part of the clamping device, a simple construction of the splice head is made possible. If at least one pull-in element is an element that is independent of the clamping device, the pull-in can be adjusted independently of the clamping device.
  • Each splice chamber section can comprise at least one nozzle for introducing a fluid, in particular compressed air and / or a water jet.
  • the splice head can have at least one fluid supply, in particular the nozzles of both splice chamber sections can be connected and / or can be connected to the same fluid supply.
  • the splice chamber sections can be designed as separate chambers and / or as part of a larger splice chamber.
  • Such a splice head can be used to connect all kinds of threads, yarns, cables or similar materials. These can consist of artificial fibers (plastics such as PE, PP, etc.), natural fibers (cotton, wool, bast, etc.) or mixed fibers.
  • the splice head according to the invention is particularly advantageously suitable for splicing threads with large diameters, in particular made of aramid, carbon or glass. These materials can include monofilaments or multifilaments. The term “yarn” is used here for all of these types of splicable materials.
  • the splice head preferably comprises two cutting elements for cutting the yarns.
  • the cutting elements are arranged in particular in the thread guiding direction before the first and after the second section of the splice chamber.
  • the cutting elements allow thread ends to be easily removed.
  • the clamping device preferably comprises a first and a second clamping element.
  • the clamping elements include clamping surfaces.
  • the clamping device defines a distance between the clamping surfaces in an open position so that a tension can be applied to the yarns when the yarn is clamped. The distance is designed in particular so that the yarn ends can be drawn in by at least 5% and preferably at least 10% of the length of the splice chamber.
  • the clamping device can comprise at least one, preferably two, extending elements.
  • the clamping device can be pneumatic and / or hydraulic cylinders include.
  • a clamping device can comprise three positions: an open position, a closed position and a retracted position. In the open position, the yarns are not clamped by the clamping device.

  • the clamping device comprises only two positions, one open and one closed.
  • the clamping surfaces comprise rough and / or adhesive surfaces to prevent the yarns from sliding.
  • a silicone clamping surface is used as the adhesive surface. Due to the flexibility of silicone, there is a good clamping effect. This can be a coating or the body with the clamping surface is made in one piece from silicone.
  • the clamping device preferably comprises pneumatic and / or hydraulic and / or electronic movement elements for actuating at least one clamping element.
