Definitions
- the present invention relates to a spinning machine with a large number of drafting units, each with upper and lower rollers and a loading arm for two adjacent drafting units, on which the upper rollers of the drafting unit are arranged as twin rollers of the two adjacent drafting units, a pair of output rollers, which is driven by an output upper roller and an output lower roller, in particular an output cylinder, is formed and with a pneumatic compression device arranged downstream of the output roller pair of the drafting system for compressing a stretched fiber structure, which has a suction pipe, the suction pipe is wrapped in a sieve element and arranged on a holder, the holder is movably mounted in a bearing and the suction tube is pressed elastically against a roller of the pair of output rollers of the loading arm by means of the holder.
- Spinning machines with a large number of drafting devices, with the top rollers of two adjacent drafting devices being arranged as twin rollers on a loading arm, are sufficiently known in the prior art.
- a corresponding machine is described, for example, in DE 29 822 763 U1.
- the spinning machine disclosed therein has a pneumatic compression device, which is provided with a suction pipe for each drafting device, the suction pipes of two adjacent drafting devices being designed as one structural unit.
- the disadvantage of the proposed machine is that the position and the angle of the suction tube on the respective roller of the pair of output rollers of the adjacent drafting units must be set very precisely in order to achieve a uniform system and to avoid irregular compression of the fiber structure.
- the object of the present invention is therefore to create a spinning machine which is characterized by a reliably uniform compression of the sliver of two adjacent drafting units.
- a spinning machine has a variety of drafting works, each with upper and lower rollers and a loading arm for two adjacent drafting units on which the upper rollers of the drafting unit are arranged as twin rolls of the two adjacent drafting units.
- a pair of output rollers is formed by an output upper roller and an output lower roller, in particular an output cylinder.
- the output roller pair of the drafting system is followed by a pneumatic Verdichtungvor direction for compressing a drawn fiber structure.
- the compression device has a suction pipe that can be aspirated. The suction pipe is wrapped in a sieve element. Fibers from the fiber structure are therefore not sucked in through the suction tube. The fiber structure can be evenly compressed and transported through the nip between the suction tube and the top or bottom exit roller.
- the sieve element is preferably a sieve belt, but can also be a sieve roller.
- the suction pipe is arranged on a holder which is movably mounted in a bearing. By means of the holder, the suction tube is pressed elastically against a roller of the pair of output rollers of the neighboring drafting units.
- two independently movable holders with their suction pipes are arranged on the two adjacent drafting systems of the loading arm.
- Each of the two holders and thus each of the suction tubes can only be moved to one of the adjacent drafting units, in particular only one of the twin rollers of the pair of output rollers of the neighboring drafting units.
- This arrangement of the suction pipe causes that after opening and closing the drafting system, for example by lifting the loading arm, a possible inclined position of one or a plurality of the rollers of the output roller pair can be compensated for by the holder.
- a reliable and uniform compression of the fiber structure, in particular on both of the adjacent drafting units, is thus created.
- the holders cause a defined and uniform positioning, in position and angle, of each of the suction pipes to one of the twin rollers of the pair of output rollers of the neighboring drafting units. This ensures, in particular, that the suction pipe rests evenly on one of the rollers of the pair of output rollers, even if the twin rollers have a different angular offset from one another.
- the holder is mounted in the position slidably, rotatably and / or tiltably. This enables a parallel alignment of the suction tube to the associated roller of the output roller pair even when they are at a great inclination to one another.
- a spring and / or a pneumatic element is arranged on the holder for elastically pressing the suction tube against the associated roller of the pair of output rollers.
- the spring and / or the pneumatic element which is also adjustable in its pressing force in a preferred Ausrete tion, ensures an even loading of the suction tube and thus for a continuous and even compression of the fiber structure.
- the holder is assigned to the loading arm, a twin upper roller axis or a loading unit arranged on the loading arm, the suction pipe being pressed against the output upper roller and / or the output lower roller, in particular the output cylinder, by means of the holder, or if the holder is a Machine frame or a twin lower roll axis is assigned, with the Suction pipe is pressed by means of the holder to the output top roller and / or the output bottom roller, in particular the output cylinder.
- This arrangement ensures that the suction pipe is pressed against the associated roller of the pair of output rollers as high and as constant as possible and thus ensures continuous and uniform compression of the fiber structure.
- the spring and / or the pneumatic element is supported alternately on the loading arm or the machine frame. This enables a simple and inexpensive construction of the spring and / or the pneumatic element.
- the spring and / or the pneumatic-specific element is arranged essentially in the center of the associated roller of the pair of output rollers. In this way, the suction pipe can be pressed onto the associated roller of the pair of output rollers as evenly as possible. This even pressure is particularly important if a particularly good yarn quality is to be produced.
- the spring and / or the pneumatic element is arranged between tween the storage and the suction pipe. In this way, the highest possible and even pressure of the suction pipe against the associated roller of the output roller pair can be achieved with little space requirement.
- a first clamping point is defined by the two rollers of the output roller pair, and a second clamping point is gebil det by one of the two rollers of the output roller pair and the screen element.
- the fiber structure is clamped at these two clamping points and compressed on the suction tube, which causes suction of the fiber structure between the two clamping points.
- the suction pipe is connected to a clamping device for the screen element.
- the sieve element which wraps around the suction pipe, is preferably placed around the suction pipe with a defined clamping force.
- the tensioning device which is arranged on the suction pipe, ensures a defined and uniform pretensioning of the sieve element on the suction pipe.
- a suction tube is arranged on the holder or the suction tube.
- the suction pipe is used to connect the suction pipe to a suction source, which is arranged in the spinning machine.
- At least one elastic connection element in particular at least one bellows, is arranged on the suction pipe for the elastic connection of the suction pipe to the suction pipe and / or to a second, in particular stationary part of a suction pipe.
- a flexible connection with the suction in the machine is necessary in order not to restrict the mobility of the respective holder and thus to ensure the movable delivery to one of the twin rollers of the pair of output rollers of the neighboring drafting works.
- a suction pipe is preferably assigned to each suction pipe of adjacent drafting devices or two adjacent suction pipes open into a common suction pipe, the two suction pipes of neighboring drafting devices being able to be designed separately or connected to one another. Separate suction pipes can thus be vacuumed independently of the neighboring suction pipe. This ensures an individual and, if necessary, individually adjustable suction from the compression device. Alternatively, it can be provided that two adjacent suction pipes lead into a common suction pipe. This results in a simple constructive solution and is in most cases sufficient for a uniform suction of two neighboring drafting systems or compression devices. It also brings advantages if the holder, the storage, the suction tube and / or the suction tube is formed in one piece, in particular from plastic. This enables simple and inexpensive manufacture of the Hal age. In the event of wear and tear, the holder can thus be replaced inexpensively and independently of the neighboring drafting systems. This leads to a constant, optimal compression of the fiber structure.
