Definitions
- the invention relates to a spinning system for melt spinning a plurality of threads according to the preamble of claim 1.
- a generic spinning installation is known from EP 0 742 851 B1.
- a plurality of spinnerets are arranged in two parallel rows next to one another for melt spinning a plurality of threads.
- the spinnerets are connected to one or more melt sources, so that a multifilament thread is extruded from each of the spinnerets.
- the spinnerets are arranged inside a heated spinning beam.
- a cooling device with a double cooling shaft is formed below the spinning beam, so that a separate cooling shaft is assigned to each of the rows of nozzles.
- the two cooling shafts interact with a common pressure chamber which is connected to a cooling current source.
- the rows of nozzles are arranged as closely as possible in order to utilize space.
- this poses the problem of the supply of cooling air, since the space available for the pressure chamber formed between the rows of nozzles is correspondingly small.
- the lowest possible flow velocities in the supply channels must be observed for the economical use of air conditioning systems.
- Another object of the invention is to keep a sufficient amount of cooling air from a cooling flow source available in a compact design of the rows of nozzles for cooling the threads.
- a spinning system with the features of the preamble of claim 1 in that the large number of spinnerets of the two rows of spinnerets is divided into several spinning stations along the longitudinal side of the machine, that the spinning stations are each assigned one of several double cooling shafts and that the middle pressure chambers the double cooling shafts are connected to the cooling power source via an air duct arranged on the side next to the machine's long side.
- the invention is distinguished in particular by the fact that the spinnerets are divided into groups by forming a plurality of spinning stations, a double cooling shaft being assigned to each group of spinnerets. This can limit the number of threads that are simultaneously cooled within the double cooling shaft.
- the cooling air supply to all double cooling shafts is ensured via an air duct located to the side of the machine's long side. A supply cross section of the air duct can thus be selected which is independent of the spacing of the rows of nozzles and can be selected exclusively according to the quantity and the permissible pressure drop in the supply system. In this way, low flow velocities of below 10 m / s can advantageously be achieved.
- the spinnerets can be arranged very closely and compactly in the rows of nozzles.
- the pressure chambers are connected to the air duct individually or in groups via cross-pieces.
- the cross connectors are advantageously formed between the spinning stations.
- the cooling shafts of the double cooling shafts each open into a common chute.
- the chutes have a shape that tapers towards the bottom, so that the cross-pieces are preferably arranged between the chutes.
- a thread closure is advantageously achieved before entry into the collecting plane by two separate preparation devices which are assigned to the cooling shafts of the double cooling shafts.
- a further preferred development of the invention is characterized in particular by the fact that the spir locations are divided into groups by forming a plurality of longitudinal modules, each group being kept the same in terms of their arrangement of the spinnerets and temperature of the spinnerets.
- the passage formed between the longitudinal modules means that each longitudinal module can be operated from both longitudinal sides of the machine. In this way, short piecing times in particular at the start of the process or after a process interruption can be achieved, since both an operator can supply the spinnerets of both rows of nozzles of a longitudinal module.
- the longitudinal modules are each formed by a box-shaped nozzle carrier, which is heated by means of a heat transfer medium and is supplied with a heat transfer medium at the end facing the passage, is particularly advantageous for uniform temperature control of the spinnerets in the spinning positions.
- a heat carrier circuit oriented in the longitudinal direction can be implemented in a simple manner by the box-shaped nozzle holder is provided with a slight inclination aligned in the longitudinal side of the machine.
- Another advantage lies in the fact that the free spaces formed by the passages within the spinning system can advantageously be used for the cooling air supply and other supply lines and supply units.
- the threads are brought together in a predetermined sequence in the collecting plane.
- sequences can be formed in which the thread family of one row of nozzles is guided next to the family of threads of the neighboring row of nozzles in the collecting plane.
- the winding device per spinning station is preferably formed by a winding machine with two winding units or respectively winding machines with one winding unit each. This makes it possible to form compact winding units suitable for high winding speeds.
- the thread sheet drawn off after the treatment is divided over the winding units in such a way that the threads of the one row of nozzles and the threads of the other row of nozzles are wound in a predetermined assignment to bobbins.
- the assignment is preferably chosen such that the threads of one of the row of nozzles are all wound onto a winding spindle of one of the winding units.
