Definitions

  • the present invention relates to a splicer for splicing yarn and a method for producing a splicer.
  • Splicing devices are known from the prior art. Splicers are commonly used to join threads, yarn or similar materials. In compressed air splicers, 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 yarn separate, become entangled and knotted together. This makes it easy to combine yarns.
  • a splicer which is composed of many different components such as a housing, a line and a splicing chamber.
  • a splicer which comprises a housing in which two holes have been drilled. A line was inserted into the holes.
  • the splicer for splicing yarn comprises a valve block for regulating a fluid flow and one or more line elements, in particular tube elements, for transporting fluids, in particular compressed air.
  • Pipe elements can be all types of tubes or pipes, i.e. hollow bodies.
  • the walls of these hollow bodies can be at least partially hollow cylindrical in shape.
  • the valve block includes a valve block housing with a valve block housing shell.
  • the valve block housing cover includes the interior of the valve block housing.
  • the one or more line elements are arranged continuously in the interior of the valve block housing.
  • continuous means that all openings and the walls of the element are arranged in the interior of the valve block housing.
  • Pipe elements only open onto the housing shell if the function of the splicer does this required. Pipe elements that do not lead to the housing shell are called inner pipe elements here. Pipe elements with at least one opening that open on the valve block housing shell are called outer pipe elements in the present case.
  • the openings of line elements can open into other line elements, in actuator elements or other elements such as nozzles or valves.
  • the openings of the line elements can open into functional elements such as flaps or similar elements, which openably close or reduce the opening.
  • Two line elements such as an outer and an inner line element can be connected to one another.
  • the line elements can have different sizes, in particular different diameters.
  • the line elements are designed in such a way that they ensure the fluid flow within the valve block housing.
  • the fluid supply connection is connected to an actuator element connection for an actuator element, for example for applying compressed air to yarn, by the line element or elements.
  • Actuator elements can include knives, flaps, clamping elements or air supply openings.
  • valve block housing is manufactured in one piece with the line element (s). This does not rule out the possibility that other elements such as valves can be inserted into the valve block housing.
  • Such a splicer is handy, light and tight.
  • Such a splicer can be used to connect all types of threads, yarns, cables or similar materials. These preferably consist of artificial fibers (plastics such as PE, PP, etc.). But you can also use natural fibers (cotton, wool, Bast, etc.) or mixed fibers. In the present case, the term "yarn" is used for all of these types of spliceable materials.
  • the line elements are preferably designed for the transport of compressed air. However, they can also be designed to transport other types of fluids. In the present case, fluids mean both gases and liquids.
  • valve block housing and the line elements are particularly preferably made of plastic such as acrylates or polymers (PLA, PS, PP, nylon, etc.).
  • plastic such as acrylates or polymers (PLA, PS, PP, nylon, etc.).
  • synthetic resins such as epoxy resins, ceramics / glass or metals such as copper, iron, steel etc. or a combination of different materials can also be used.
  • the valve block housing is preferably enclosed by an outer housing.
  • the valve block housing can include openings for fastening the outer housing.
  • the outer housing can be detachably connected to the valve block housing.
  • An outer casing stabilizes and protects the inside.
  • the outer housing can be ergonomically adapted to one hand. This simplifies operation by a user.
  • the outer housing can be made by injection molding.
  • the valve block housing preferably has at least one connection interface for fastening a splice head.
  • the valve block housing is particularly preferably connected fixedly or detachably to a splice head.
  • a splice head as part of the valve block housing enables a simple and compact design of the splicer.
  • the splicer comprises at least one nozzle for applying the fluid flow to the yarn.
  • the nozzle or nozzles are arranged on and / or in a splice chamber.
  • the fluid flow can be applied precisely through a nozzle.
  • the flexible arrangement of the nozzle or nozzles enables precise alignment and thus a good and stable splice.
  • the line elements can comprise at least one outer line element with at least one opening on the valve block housing shell and / or one inner line element without an opening on the valve block housing shell.
  • a line connection of a fluid supply connection to an actuator element connection is possible simply and efficiently by external line elements. This also enables easy ventilation of the line elements or removal of existing waste materials such as fibers or dust. The flow of fluid through inner line elements is efficient because the pressure loss is low.
  • the splicer can comprise at least one control element, in particular a valve, for controlling the fluid flow.
  • the at least one control element is connected to other control elements, regulating elements or actuator elements via line elements.
  • Control elements regulate whether and / or where the fluid can flow through.
  • the splicer can comprise three control elements. This makes it easier to control the fluid flow.
  • the control elements can be inserted or used in the valve block housing. This enables simple and quick maintenance or repair.
  • the splicer in particular the valve block housing, can comprise at least one support element for supporting at least one line element and / or a control element. This enables a simple and compact construction of the splicer.
  • the support element or elements can be connected to the outer shell of the splicer or to the valve block housing shell or be connectable, in particular be made in one piece with the outer shell or with the valve block housing shell. This makes the arrangement stable and compact.
  • One or more outer and / or inner line elements can comprise one or more curved sections.
  • a line element with at least one bend section By manufacturing a line element with at least one bend section, a compact structure of the lines and thus a good utilization of the interior of the valve block housing and a compact structure of the line network is possible.
  • the outer and / or inner line elements are made in one piece with one or more curved sections.
  • At least one line element can be arranged at least partially parallel to another line element. This leads to a simple and compact line network.

  • the duration of this controlled sequence can be changed by the regulator by increasing or decreasing the flow of the fluid.
  • the fluid flow can be automatically switched on by a time switching element when the splice chamber is sealed and / or switched off when a certain time has passed. This can ensure, for example, that the compressed air cartridge is emptied less quickly.
