Definitions

  • the invention relates to a splicing head for a splicing device, a splicing device with at least one splicing head, and a method for splicing yarn with a splicing head.
  • Splicers are commonly used to join threads, yarn, or similar materials.
  • compressed air splicers compressed air is applied to the yarn, particularly to the ends of the yarn, to swirl them, causing the filaments of the yarns to open and intertwine with each other. This makes it easy to connect yarns. It is particularly important for a clean connection between the yarns that the yarn ends are spliced well, otherwise they can get caught on eyelets.
  • the thread splicing device for splicing with a splicing head according to the preamble of claim 1 is known.
  • the thread splicing device includes a splicing channel, a spring wire for clamping the thread and a loop puller for pulling thread ends into the splicing channel.
  • a splicing head for a splicing device for a splicing device, a splicing device with at least one splicing head, and a method for splicing yarn with a splicing head according to the independent claims.
  • a splicing 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 splicing head so that it can be operated independently, so that the clamping device can be actuated before or after the splicing chamber is closed.
  • the splicing head comprises at least one pull-in element for ensuring that the yarn ends are arranged in the splicing chamber, in particular for pulling the yarn ends into the splicing chamber.
  • the yarn ends are often slightly longer or approximately the same length as the splicing chamber and are therefore not completely arranged in the splicing chamber. This means they are not sufficiently exposed to the splicing medium, such as compressed air or water jets.
  • the feed element can ensure that the yarn ends are tightened and are completely in the splicing chamber after readjustment. This makes it easier for the yarn ends to be spliced.
  • the feed element is designed such that the distance from an entrance of the yarn into a splice chamber to one Clamping element of a clamping device is extended and/or extendable. 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 feed element can be movable in the splicing chamber, so that the yarn can be brought into a curved configuration by acting on a surface of the 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 splicing chamber can be designed to be extendable and/or displaceable, in particular the splicing chamber can comprise splicing chamber sections, the splicing chamber sections being displaceable in the thread guiding direction so that at least one yarn end is completely located in the splicing chamber section.
  • the thread guide direction is the direction along which the thread is inserted into the splice head.
  • the splicing head preferably comprises further, in particular two further, clamping devices.
  • the clamping devices are preferably arranged in the thread guiding direction before and after the splice chamber sections.
  • at least one of the further clamping devices is arranged on the splicing head in a pivotable and/or displaceable manner, preferably displaceable in the thread guiding direction,
  • the retraction 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 together.
  • the clamping devices can each comprise at least two, preferably three, clamping elements.
  • the clamping device may include two single-sided clamping elements and a 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.
  • 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 splicing head is made possible. If at least one feed element is an element independent of the clamping device, the feed can be adjusted independently of the clamping device.
  • Each splice chamber section can include at least one nozzle for introducing a fluid, in particular compressed air and/or water jet.
  • the splicing head can have at least one fluid supply, in particular the nozzles of both splicing chamber sections can be connected and/or connectable to the same fluid supply.

  • the splicing 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 splicing chamber.
  • the cutting elements make it possible to easily remove yarn ends.
  • the clamping device 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 clamping the yarn.

  • the clamping device can comprise at least one, preferably two, extending elements.
  • the clamping device can include pneumatic and/or hydraulic cylinders.

In the open position, the first or second clamping element may be in an extended position. In a closed position, the yarns are clamped between the clamping elements. In the closed position, both clamping elements can be in an extended position, in particular one clamping element can be in a semi-extended position.
  • one clamping element In a feed position, the yarn ends are drawn into the splice chambers.
  • one clamping element In the retracted position, one clamping element can be in a retracted position and the other in particular in a fully extended position.
