Definitions
- the invention relates to a metering pump for supplying a thread fixing fluid for fixing a thread end to a spool package and an associated winding device for winding a synthetic thread with the metering pump.
- thread produced from a polymer melt is drawn off and treated and then wound into a spool.
- the spool is used to collect and store the thread and is then fed into a further processing process. To ensure that the extrusion and production of the thread can take place continuously in the melt spinning process, the thread is continuously wound into spools without any major interruptions.
- winding machines are used that have two winding spindles projecting from a rotatably mounted spool turret.
- the winding spindles can be alternately moved into a winding position and a removal position by rotating the spool turret.
- the thread In the winding position, the thread is wound onto the respective winding spindle to form the bobbin. As soon as the bobbin has a predefined final diameter, the bobbin is called a full bobbin or bobbin package.
- the winding spindle is guided into the removal position with the full bobbin. In this state, the thread is wound around the circumference of the bobbin to form a final winding and is then caught and separated by the other winding spindle, which is moved into the winding position.
- the thread is then wound into a new spool on the other spool spindle.
- the full bobbin held by the winding spindle in the removal position is removed from the winding spindle after braking until the winding spindle comes to a standstill and is fed to a further processing process.
- a loose thread end that occurs on the final winding must remain as close to the circumference of the bobbin as possible in order to avoid any unwanted desired unwindings during the removal of the full bobbin from the winding spindle and during transport.
- thread fixing devices In order to fix the loose thread end to the full bobbin when changing the bobbin, thread fixing devices are known which can be used with a winding device of this type.
- DE 44 13 885 A1 and WO 2022/023051 disclose corresponding thread fixing devices, wherein the loose thread end can be fixed to the final winding of the thread by supplying a thread fixing fluid.
- the thread can be moistened before cutting to ensure that the thread adheres as closely as possible to the circumference of the full spool.
- the thread fixing device can optionally have a pressure roller that is placed around the circumference of the full bobbin. What is relevant here is that the corresponding thread fixing fluid is supplied to the thread fixing devices in sufficient quantity and precisely. The quantity of thread fixing fluid must be supplied to the thread fixing devices in sufficient quantity and promptly.
- a metering pump for supplying a thread fluid for fixing a thread end of a synthetic thread to a spool package from a winding device for winding the synthetic thread, with a first piston in a fluid pump housing for conveying the thread fixing fluid and a second piston in a drive medium pump housing for driving the first piston.
- the first piston is mounted to the second piston by means of a common piston rod.
- the design of the dosing pump with a first and a second piston with a common piston rod is economical in production and effective in pumping.
- the fluid pump housing has a first piston chamber for conveying the thread fluid. This offers the advantage that a precise metering of an associated thread fixing fluid is possible in the first piston chamber and, in addition, a separation from the associated drive medium for driving the metering pump is possible.
- the first piston chamber has on the one hand a fluid channel for metering the thread fluid and on the other hand Above the fluid channel there is a piston rod bore for guiding the piston rod.
- the drive medium pump housing has a second piston chamber for driving the second piston.
- the separation of the dosing pump into a fluid pump housing and a drive media housing enables precise control of the quantity of the thread fixing fluid and also precise control of the thread fixing fluid delivered via the fluid pump housing.
- the quantity of the thread fixing fluid and the conveying speed and flow rate of the thread fixing fluid can be precisely regulated and controlled.
- This can be controlled and regulated with appropriate motive medium storage and/or pressure controls that can be coupled to the motive medium pump housing.
- the second piston chamber has, on the one hand, a first drive medium supply channel for supplying a first drive medium to the second piston on the one hand and, on the other hand, opposite the first drive medium supply channel, a second drive medium supply channel for supplying a second drive medium to the second piston on the other hand.
- a corresponding regulation or control system for the drive medium supply can also be switched on.
- the fluid housing and the drive medium pump housing have a common piston rod bore.
- the piston rod bore connects the first piston chamber with the second piston chamber in such a way that the piston rod can be moved at least partially from the first piston chamber into the second piston chamber and vice versa.
- the fluid pump housing has a check valve on or near a fluid supply channel for supplying the thread fixing fluid into the fluid pump housing.
- the fluid outlet of the first piston chamber of the fluid pump housing has a check valve and/or the first piston chamber and/or the second piston chamber has a vent.
- the number of dosing pumps corresponds to the number of winding points at which a free thread end is to be fixed to a final winding of a bobbin package.
- each winding point at which a thread is wound on the winding device can be safely supplied with a thread fixing fluid.
- the thread fixing fluid comprises a liquid, in particular water and/or a preparation agent
- the propellant comprises a gas, in particular compressed air
- the fluid pump housing is coupled to a pressure dispenser for providing the driving medium and the driving medium pump housing is coupled to a fluid dispenser for storing the thread fixing fluid.
- a high-quality supply of the thread fixing fluid in the desired amount for each winding point can be carried out promptly and safely without too much thread fixing fluid being provided and wasted when fixing the loose thread to the bobbin package.
- the dosing pump, the pressure dispenser and/or the fluid dispenser are coupled to a control of a winding device for winding a synthetic thread.
- a winding device for winding a synthetic thread with a metering pump is provided with a traversing device for traversing the synthetic thread onto a winding spindle on a winding station to form a winding package and an alternating cutting device for severing the synthetic thread and a fluid application device for applying a thread fixing fluid, wherein the thread fixing fluid is supplied by means of the metering pump in a predetermined quantity.
- the dosing pump can be used to safely and reliably supply a thread fixing fluid to the winding package in sufficient quantities and in a timely manner through the drive agent feed. This ensures that a loose thread can be safely fixed to the winding package at any time when the winding package is removed.
- the winding device has a plurality of winding stations, each winding station being assigned a metering pump.
