Definitions

  • the invention relates to a textile machine that produces take-up packages.
  • sensor devices that monitor the most varied operational or process states.
  • pneumatic, electropneumatic or electromagnetic sensor devices are known in this regard.
  • devices are controlled that, for example, initiate a package lifting device, the clamping of a yarn, a yarn cut or the stopping of a spindle.
  • pilot valve between the sensor device and the device to be controlled, which in turn is designed, for example, mechanically as a push button valve or pneumatic actuating valve, is also known.
  • the presence of the yarn is monitored by a mechanical element positioned by the yarn. If there is a yarn break, the mechanical element falls around an axis of rotation due to its own weight, and thus operates the switch pin of a pilot valve.
  • the pilot valve is connected to a control valve, which controls a pneumatic actor, in this example the package lifting device.
  • the control valves that have been previously used in textile machines that produce take-up packages have a so-called membrane sealing ball design.
  • a sealing ball is connected with a membrane via a plunger.
  • the membrane is located between a front and a rear chamber. Air streams into the rear chamber via a main line and, where applicable, a fixed throttle valve. This deforms the membrane towards the front and the plunger closes the front seal seat in the valve housing with the attached sealing ball.
  • the membrane with the attached plunger and the sealing ball is, however, a complex component in terms of production technology, for which it is difficult to adhere to the required tolerances. This creates the risk that an undefined state of uncertainty occurs during operation, resulting in the membrane fluttering.
  • the sealing ball then is not positioned in a defined way at the relevant seal seat, and lasting leaks occur via the ventilation hole. In addition, the sealing ball is periodically put under stress.
  • the invention comprises a textile machine that produces take-up packages with control valves.
  • One aspect of the present invention therefore comprises a textile machine that produces take-up packages with control valves, whereby the control valves each have a valve body, a piston and a plunger, whereby the plunger comprises a front seal seat and a rear seal seat as well as seals, with which outlets, such as a main line, a pilot line, a connection and at least one vent are alternately sealable in the valve body, and the piston has a piston seal that separates two air circuits from each other.
  • the textile machine that produces take-up packages is also characterized in that there are contact surfaces in the valve body at which the corresponding surfaces of the front and rear seal seats of the plunger can be brought abutment.
  • the path of the plunger with respect to the relevant seal is restricted in the sealed surface.
  • the maximum deformation of the seals can be specified in advance through the defined deformation limitation of the seals and the seals cannot slide too far into the sealing gap. This guarantees a long lifespan for the seals.
  • control valves can be practically and economically produced.
  • material influences above all are not so significant and disruptive to functionality, as is the case with the membrane sealing ball design.
  • this type of seal seat is sufficiently durable for the expected number of switch cycles with a textile machine that produces take-up packages.
  • the maximum piston path is designed as a short-stroke piston with two conical seal seats, a compact structure of the control valve is maintained, whereby the piston path is advantageously designed between 0.8 mm and 5 mm.
  • control valves in a textile machine that produces take-up packages can result in an economical and compact textile machine being offered without having to accept impacts on quality during the manufacture of take-up packages due to errors in functioning of the control valve. For example, if a take-up package was not taken up by the drive roller following a yarn break, it remains on the drive roller and is driven at a diameter that can lead to yarn damage. This type of design does not lead to any increased maintenance costs or an increased need for repairs either.
  • the surfaces corresponding to the seals are designed in a conical shape.
  • the piston and the plunger are designed in two pieces.
  • connection between the two parts is secure and can be done using a thread.
  • the two parts can also be connected via press fit or with an adhesive bond. In principle, all joining techniques are possible in the context of the invention that allow for a stable connection of the piston with the plunger.
  • a supporting element is present that is positioned so that the piston is secured on the plunger and the piston seal is affixable to the piston.
  • the piston seal is manufactured without a nut, because the supporting element affixes the piston seal, the mounting of the piston seal is simplified.
  • the piston seal is positioned at the piston and affixed to it via the supporting element, while previously assembly had to be done in a very painstaking manner in order to ensure functionality.
  • the attachment of the piston seal to the piston can moreover be done without tools and the risk that the seal surface of the piston will be damaged is eliminated.
  • the supporting element ensures a constant secure fit of the piston seal on the piston including during use in the textile machine.
  • the supporting element secures the piston on the plunger, so that during the entire lifetime a defined positioning of the piston on the plunger and consequently the error-free functioning of the control valve are ensured.
  • a connection designed as a bottleneck is integrated into the plunger between the main line and the pilot line.
  • the air can flow from the main line to the rear chamber or pilot line.
  • the bottleneck can be integrated into the plunger through a separate fixed throttle.
  • a bore hole can preferably be present in the plunger into which a separate fixed throttle is set.
  • the seals are designed as O-rings.
  • O-rings are economical and can be acquired as standard products.
  • the supporting element can be attached to the plunger without destruction and can be detached.
  • the supporting element can, for example, after the piston that has the piston seal has been put on, with a plunger and a nut that has been moulded into the plunger, be pushed into the nut from the side like a lock washer and snaps into place there. This not only makes the assembly of the piston seal simpler as already described, but also makes disassembly easier. Replacing the piston seal is thus possible without using tools, without the risk that the sealed surface of the piston becomes damaged when removing the piston seal.
  • control valve is designed as a single or multiple unit.
  • the control valve can be constructed in either an individual design or a multiple design, for example a double design. Depending on the area of application, the control valve can be designed according to requirements in the context of the invention. In this case, two positions or workstations on the textile machine are controlled by one control valve that is designed in a double design. A multiple or double design is essentially more economical to produce.
  • FIG. 1 is a schematic representation of a control valve with closed front valve seat
  • FIG. 2 is a schematic representation of a control valve with closed rear valve seat
  • FIG. 3 is a schematic representation of an embodiment example of a supporting element according to the invention.
  • FIG. 4 a schematic representation of a part of the plunger with the piston and supporting element positioned next to it.
  • FIG. 1 as an example a schematic view of the structure of a control valve 1 with closed front seal seat 5 is shown.
  • the control valve 1 comprises a valve body 2 as well as a piston 3 and a plunger 4 .
  • a piston seal 8 separates the two air circuits or the front chamber 17 and the rear chamber 18 .
  • a supporting element 10 is in turn positioned below the piston seal 8 .
  • the piston seal 8 is affixed to the piston 3 .
  • valve body 2 (divided into three in this embodiment example) has contact surfaces 11 , at the corresponding surfaces 12 , that are designed at the front and rear seal seats 5 , 6 of the plunger 4 , that can be transported to the system.
  • the axis bore hole or the small diameter is designed in such a way as regards flow technology that a throttle function is enabled.
  • the piston 3 pushes into the front position due to the large rear effective area and seals the conical front seal seat 5 by means of a seal 9 , designed in this embodiment example as an O-ring.
  • the corresponding surfaces 12 of the front seal seat 5 are transported to the system at the contact surfaces 11 in the valve body, so that the O-ring of the front seal seat 5 is subject to a defined maximum deformation and cannot be squeezed into the seal seat.
  • connection 16 to which, for example, a simple pneumatic cylinder is connected and the pneumatic cylinder can travel into its operating position via a vent 15 .
  • FIG. 2 shows the control valve 1 with closed rear seal seat 6 .
  • a fixed throttle 13 is attached to the plunger 4 , through which air streams into the rear chamber 18 .
  • the control valve 1 should be switched.
  • the pre-control line 19 is released, i.e. opened, at the control valve 1 via a (not shown) pre-control valve.
  • the pressure in the rear chamber 18 reduces, because more air flows out than can flow in via the fixed throttle 13 into the plunger 4 , which means that the piston 3 moves to the rear, the conical front seal seat 5 opens, releases the path of the main air through the front chamber 17 to the connection 16 to the pneumatic cylinder and the piston 3 moves against the (also conical) rear seal seat 6 , causing the entry to the vent 15 to close.
  • the corresponding surfaces 12 of the rear seal seat 6 are transported to the system at the contact surfaces 11 in the valve body 2 , so that the O-ring of the rear seal seat 6 is subject to a defined maximum deformation and cannot be squeezed into the seal seat.
  • FIG. 3 shows an example of a supporting element 10 according to the invention.
  • the supporting element 10 is designed as a clamp here, that can be pushed into a corresponding nut 7 of the plunger 4 .
  • the piston seal 8 can be attached easily and without a tool to the piston 3 .
  • the piston 3 is secured to the plunger 4 through the supporting element 10 .
  • FIG. 4 shows a schematic representation of a part of the plunger 4 with the piston 3 positioned next to it.
  • the piston seal 8 is positioned below the piston 3 .
  • the supporting element 10 is latched onto a nut 7 , that is present in the plunger 4 , which ensures on the one hand the proper positioning of the piston 3 at the plunger 4 , and on the other hand attaches the piston seal 8 to the piston 3 .
