    专利说明:

    The invention relates to a drafting system for a spinning preparation machine, in particular for a route, carding or comber, according to the preamble of claim 1.
    In a known device (DE 19 548 840 A) the drafting system is loaded during operation, i. Upper and lower rollers and intermediate sliver touch each other under pressure. These are placed on the top rollers pressure medium, which in turn are attached to the pressure arms. The pressure arms are pulled by means of a locking device in the direction of the drafting, so that the upper rollers are pressed onto their associated lower rollers. The locking device has two loading hooks, each pressure arm is assigned a load hook. The loading hooks engage a pin per pressure arm, whereby a tensile force exerted on the load hooks is transmitted to the associated pressure arm. Upon release of the pressure arms by the locking device of the loading hook, after he no longer exerts tensile force on the pressure arm, pivots away from the bolt so that now the pressure arms are wegschwenkbar. The pressure arms exert no more power on the drafting rollers. The load of the rollers is now still by the weight. The locking device, which allows to press and lock the pressure arms with the upper rollers on the lower rollers, consists of a locking element, which acts on a control element and causes the loading hook from its open position to its closed position passes. The bolt is always positioned in the same position in the closed state of the drafting system. This causes the pressure means exert a predetermined force on the drafting cylinder via an adjustment. The magnitude of the force applied by the control does not affect the force with which the top rollers are pressed against the bottom rollers. The position of the load hook and thus also the pressure arms is always the same in the closed position. The control consists of a pneumatic cylinder, which is connected to a control valve. The control valve in turn is controlled by a controller. In this device is located transversely to the fiber material flow direction (sliver running direction) a rod around which grip the spring and simultaneously pneumatically operated load hooks. The known device is complex in terms of investment. The load hooks on the one hand and the pressure arms on the other hand, each having its own pivot point are rotated in opposite directions. A disadvantage is that the drafting system is initially unlocked with a separate locking device, wherein in a first operation, the loading hooks - seen in the direction of fiber travel - are rotated counterclockwise. After unlocking the pressure arms are then separately and separately manually pivoted away in a second operation in a clockwise direction.
    The invention is therefore an object of the invention to provide a device of the type described above, which avoids the disadvantages mentioned, which allows in particular a structurally simple way the operation when unlocking / opening or closing / locking with a single hand.
    The solution of this object is achieved according to the invention by a drafting system with the features of independent claim 1.
    The dependent claims have advantageous developments of the invention drafting the subject.
    Another embodiment of the inventive device is characterized in that at least two unlocking or locking devices are provided which are actuated by the same handle.
    The invention will be explained in more detail with reference to exemplary embodiments illustrated in the drawings.
    It shows:<Tb> FIG. 1 <SEP> schematically side view of the inventive drafting system of a route,<Tb> FIG. 2 <SEP> a pressure arm according to section I-I according to FIG. 1 in the unlocked and opened (swung-open) position,<Tb> FIG. 3a to 3d <SEP> the locking device in the locked closed position (FIGS. 3a, 3c) and in the unlocked open position (FIGS. 3b, 3d) and<Tb> FIG. 4 <SEP> the unlocking or locking device in combination with the opening and closing device.
    According to Fig. 1, a drafting system S, e.g. Trützschler track TD 08, available. The drafting system S is designed as a 4-over-3 drafting system, that is, it consists of three lower rollers I, II, III (I output lower roller, II middle lower roller, III input lower roller) and four top rollers 1, 2, 3rd 4. In the drafting system S, the warp of the fiber structure 5 takes place from several slivers. The delay is composed of pre-delay and main delay. The pairs of rollers 4 / llI and 3 / II form the Vorverzugsfeld, and the roller pairs 3 / II and 1.2 / I form the main drafting field. The output lower roller I is driven by the main motor (not shown) and thus determines the delivery speed. The input and middle bottom rollers III and II are driven by a control motor (not shown). The top rollers 1 to 4 are pressed by pressure elements 91 to 94 (loading device) in pivotable about pivot bearing arms 11a to 11 d (see Fig. 2) against the lower rollers I, II, III and obtained via friction thus their drive. The direction of rotation of the rollers I, II, III; 1, 2, 3, 4 is indicated by curved arrows. The fiber structure 5, which consists of a plurality of slivers, runs in the direction A. The lower rollers I, II, III are mounted in punches 16a, 16b (see Fig. 2), which are arranged on the machine frame 17.
    2, the upper roller 4 is associated with the portal-shaped pressure arm 11a, which consists of two lateral pneumatic cylinders 9a1 and 9a2 (pressure elements), a common support element 12a, two holding elements 13a1 and 13a2 and two intermediate elements 14a1 and 14a2. The pressure arm 11a is pivoted together with the top roller 4 about a pivot bearing 10 which is attached to the punch 16a. The cover elements 13a1 and 13a2 are - seen in side view - angular (rectangular), wherein the one angle arm of the cover 13a1 each rotatably mounted in the region of its free end on the pivot bearing 10. The other angle arm of the cover 13a2 has in the region of its free end on a part of a locking device 15, the Schliesserklinke 21 with a fixedly mounted on the machine frame 17 pin 22 in and out of engagement (see Fig. 3a to 3d). The pressure arm 11a is shown in the unlocked and opened position.
    According to FIGS. 3a to 3d, the locking mechanism 15 consists of a Öffnerklinke 20, a Schliesserklinke 21 and a stationary pin 22. The Öffnerklinke 20 and the Schliesserklinke 21 are substantially formed as a double lever, each about a hinge 23 and 24 are rotatable. Furthermore, there is a handle 33 (see Fig. 4) which applies a force P in the direction of the arrow B to the one lever arm 201 of the open pawl 20. The Öffnerklinke 20 is rotatably mounted about the pivot bearing 23, the Schliessklinke 21 is rotatably mounted about the pivot bearing 24. Between the opener pawl 20 and the closing latch 21, a tension spring 25 acts (see Fig. 3c, 3d). The tension spring 25 engages with its one end to a projection 26 on the lever arm 202 of the Öffnerklinke 20 and with its other end to a lug 27 on the lever arm 212 of the Schliesserklinke 21 at. With 28 a stop is called.
    The lock is shown in Figs. 3a, 3c in the closed state. The lock is released by applying the force P to the opener pawl 20 in the direction B indicated in FIG. 3a. This is done by tilting the handle 33 forward. As a result, the opener pawl 20 according to FIG. 3 c is rotated in the counterclockwise direction according to arrow C about the pivot joint 23. The nose at the end portion of the lever arm 202 of the Öffnerklinke 20 slides from a recess 21 at the end portion 212 of the Schliessklinke 21 and the tension spring 25 rotates the Schliesserklinke 21 when opening the drafting system S (or the pressure arms 91 to 94) in the counterclockwise direction as indicated by arrow D and provides the bolt 22 free (Fig. 3b, 3d). A further recess 21 in the latch latch 21 moves away from the bolt 22. After unlocking and when opening the drafting system S, the Öffnerklinke 20 and the Schliesserklinke 21 in the direction of arrows E and F are shifted upward (Fig. 3d ). The contour of the recess 21 has a certain pressure point effect.
    For closing and locking the operation described with reference to FIGS. 3a to 3d runs in the reverse order. Starting from the unlocked and opened position shown in FIGS. 3b, 3d, the unlocking or locking device 15 is transferred into the locked closed position shown in FIGS. 3a, 3c. Here, the Öffnerklinke 20 and the Schliesserklinke 21 are displaced in the direction opposite to the arrows E and F shown in Fig. 3d down.
    According to Fig. 4, an opening and closing device 29 is present, which cooperates with the ent or locking device 15 in combination. On the portal arm 14a2ist outside a pivot bearing 30 is mounted, on each of which one end of two rigidly interconnected lever arms 31, 32 of a double lever-type link device is pivotally articulated. At the other ends of the lever arms 31 and 32, a handle 33 and a bolt 34 are mounted. When the handle 33 is pushed up in the direction of the arrow I, the bolt 34 is moved in the direction of the arrow L and presses the open pawl 20 (see Fig. 3d), whereby unlocking occurs. At the same time, the entire pressure arm 11a is rotated about the pivot bearing 10 in the direction of the arrow H by the movement of the handle 33 in the direction I, so that the pressure device or the drafting system S is opened (see FIG.
    The hinges 23 and 24 are mounted (not shown) on the portal arm 14a2. Because of this connection, when opening by the movement of the handle 33 in the direction of arrow I together (mechanically coupled) of the pressure arm 14a pivoted in the direction H and the unlocking or locking device 15 is displaced in the direction of E and F. In a corresponding manner when closing by the movement of the handle 33 in the direction of arrow K together (mechanically coupled) of the pressure arm 14a pivoted in direction G and the unlocking or locking device 15 is displaced in the direction opposite to the arrows E and F.
    Further developments and advantages of the device according to the invention are:Height adjustment of upper part of drafting body to lower part possible by means of lockable boltsMechanics can be taken up with, structurally also possible that this remains belowopener pawl can be omitted if hook solution is used; Actuator unlocks only a rotatably mounted hook, which is sprungSolution with / without overtravel (positive and frictional / frictional connection)Possibility of an emergency release is given; if the actuator fails, the opening pawl can be rotated by means of a screwdriver or the like from the locking latchSafety ensured by monitoring the closing edge by means of a proximity switch.
