Definitions

  • the invention relates to a winder with a thread laying device.
  • the thread laying device has a housing, in which a drivable having an endless thread groove Reverse thread shaft is rotatably mounted.
  • a traverse guide has a basic body, one in the thread groove of the reverse thread shaft engaging boat and a thread guide.
  • the traverse thread guide is axial due to the reverse thread shaft Direction reciprocally driven, the housing a has slot-shaped opening through which the thread guide of the Traversing thread guide from the housing of the thread laying device protrudes.
  • Such a winding machine is preferably around a winding machine for winding a continuously thread running onto a bobbin. However, it can also be another design of a winding machine.
  • a winding machine of the type described in the opening paragraph is known from DE 195 36 761 A1 .
  • the bobbin winder has a thread laying device with a housing in which a drivable reversible thread shaft having an endless thread groove is rotatably mounted.
  • a traversing thread guide has a base body, a shuttle engaging in the thread groove of the reversing thread shaft and a thread guide. The traversing thread guide is driven back and forth in the axial direction by the reversing thread shaft, and the housing has a slot-shaped opening through which the thread guide of the traversing thread guide protrudes from the housing.
  • the traversing thread guide For the radial guidance of the traversing thread guide, its base body is connected to two spaced guide rods 5 which extend parallel to the axis of the reversing thread shaft, the base body having two circular bores through which the cylindrical guide rods extend.
  • the guide rods extend over the entire length of the reverse thread shaft or the area of the reverse thread shaft in which the endless thread groove is present.
  • the guide rods must run exactly parallel.
  • the separate guide rods have to be manufactured, hardened and ground precisely. When installing the guide rods, make sure that they are aligned exactly.
  • the winding machine has a thread laying device with a housing, a reversing thread shaft and a traversing thread guide.
  • Two parallel guide rails are provided on the housing and are in contact with the base body of the traversing thread guide in such a way that it is guided radially.
  • the guide rails must be manufactured separately, hardened and ground in the contact area with the base body of the traversing thread guide. Then the guide rails are screwed to the housing, for which purpose a corresponding milling is attached to the housing. The milling causes a structural weakening of the housing.
  • the processing of the guide rails is relatively complex and expensive.
  • the invention has for its object to provide a winder to provide a thread laying device in which the radial guiding of the traversing thread guide inexpensively and with few components is realized.
  • the traversing thread guide is guided radially no longer outside the housing or in the Area of the slot-shaped opening of the housing, but in Realized inside the housing on the reverse thread shaft.

This means that the guide bush in connection with the Basic body of the traversing thread guide the entire scope of Reverse thread shaft encloses. This has the advantage that a secure radial guidance of the traversing thread guide on the Circumferential surface of the reverse thread shaft is guaranteed.
  • the guide bush or the base body the traversing thread guide has a bore into which the boat is inserted so that it is free in the hole is rotatable. The free rotation of the boat must be guaranteed so that it does not destroy the boat Driving through the reversal of the thread groove of the reverse thread shaft can come.
  • the guide bushing can also partially extend along its circumference be open.
  • the guide bush must do this be closed at least so far that they are in the radial direction is not removable from the reverse thread shaft, so that the radial Securing the traversing thread guide is always guaranteed.
  • the not completely closed Training the guide bush has the advantage that the mass or the weight of the guide bush and the entire traversing thread guide is reduced.
  • the inner surface to be machined the guide bush is smaller than that of a closed one Guide bush, which increases the grinding effort further reduced. It is to reduce the mass of the guide bush also possible to make radial bores or the like in this.
  • the reverse thread shaft can have a plurality of endless thread grooves have, each with a traversing thread guide is drivable.
  • the thread grooves are axially spaced, so that the traversing thread guide is also axially spaced move.
  • the traversing thread guides can do this be inserted in the thread grooves that they are always in move the same distance from each other.
  • the traverse guide can also be moved out of phase with each other.
  • Two thread guides arranged offset by 180 ° can be provided his.
  • the housing then has two 180 ° offset slit-shaped openings. That way you can Two thread guides are used to separate the thread on two Wind up spools.
  • the traversing thread guide can have a cover that is under Formation of an air gap is connected to the base body, with a sealing tape for sealing the slit-shaped Opening of the housing extends through the air gap.
  • a sealing tape for sealing the slit-shaped Opening of the housing extends through the air gap.
  • the energy consumption of the Dishwasher rises with that caused by the pollution increasing friction. There is a risk that the traverse guide gets stuck and damaged in these dirt particles becomes. For example, cause such pollution a destruction of the traversing guide.
