Definitions

  • the present invention relates to a can changer for a spinning preparation machine, preferably for a track, carding machine or comber, wherein the can changer has at least two Kannengreif drivenen, each with a jug between a first position and a second position can be brought, each Kannengreif featured a stop surface for the jug and a relative to the stop surface movably mounted retaining element. Furthermore, a method for changing cans on a spinning preparation machine, preferably a line, carding machine or comber, with the aid of a can changer is proposed with which the cans are spent during the can change between a first position and a second position.
  • Dual head sections are known in which two cans stand next to one another and are pushed by a cross strut under the drafting systems from one waiting position to the next or to the respective filling position, the cross strut being connected to respective chain drives on both sides.
  • the DE 31 33 438 A1 a double head section, wherein the means for replacing the cans are adapted to move the empty cans in a straight line against the working direction of the stretching heads in the filling stations and the filled cans in the same direction in adjacent removal stations. From the unloading stations, the cans are finally ejected transversely to the working direction on both sides of the route.
  • the object of the present invention is therefore to provide an improved changing device and a corresponding can change method, wherein it should be ensured that the cans are securely held during their movement without disturbing guide rails and can be quickly removed after the change process again from the changing device.
  • each holding element can be fixed by means of an actuating device between a closed position in which a jug can be fixed by means of the holding element and the associated abutment surface of the respective jug gripping device, and an open position in which no fixing of the jug takes place.
  • the can changer preferably comprises two can-gripping devices with the aid of which two cans can be moved simultaneously between said positions as required.
  • the cans Due to the active fixation, in particular by positive locking, the cans can therefore also be guided on a circular path, so that the can changer can preferably be used in connection with so-called double-head sections, which are capable of using two drafting two stretched fiber strands to create in parallel.
  • the fiber strands are in turn deposited simultaneously in two cans, so that it is particularly advantageous in this case if two cans can be changed at the same time.
  • the holding elements may in this case be designed tiltable, rotatable or displaceable relative to the respective stop surfaces. In any case, it should be ensured that the cans in the open position of the respective holding element can be introduced into or removed from the can changer, while they are fixed in the closed position thereof relative to the can changer.
  • the can changer comprises a rotatable by means of a drive turnstile with a plurality of rotating arms, which extend radially outwardly starting from a rotation axis of the turnstile, wherein the stop surfaces and the holding elements are formed by portions of the rotating arms.
  • Such an embodiment allows the fixing of a jug between two rotating arms. If a double-head section is used, it would be conceivable, for example, to equip the turnstile with four rotating arms so that two cans in the region of the filling positions of the line and two cans can be fixed on corresponding empty can places.
  • a rigid or rotatable with the turnstile platform can be placed, which can be arranged, for example sunk in a foundation.
  • the foundation for example, a hall floor supporting the multi-head section, is in this case just in the platform (which may be formed, for example, by a flat, in particular disc-shaped pad) over.
  • the cans can be moved in this case without much effort in the area of the rotating platform or the hub, without causing corresponding unevenness or sloping ramps would have to be overcome.
  • the rotating arms has an end region facing away from the axis of rotation in the radial direction, in each of which an actuating device is arranged.
  • the actuating device with the aid of which the respective holding elements can be moved between their open and closed positions, are thus easily accessible from the outside. They can therefore be operated manually by the operator of the corresponding spinning preparation machine without the risk of injury threatens.
  • the holding elements of two adjacent Can gripping devices are movable by a common actuator. This allows a particularly fast opening or closing of two holding elements by a single movement.
  • the holding elements can be arranged, for example, on both sides of the actuating device in order to ensure an equilibrium of forces when closing or opening the holding elements.
  • the turnstile has at least one actuating device and two retaining elements, wherein the retaining elements are movably mounted in opposite directions with respect to the actuating device and each form a can gripping device with the abutment surfaces formed by the corresponding adjacent pivot arms.
  • the turnstile has four pivot arms, then in this case two of the pivot arms would each have one actuator and two support members aligned in opposite directions, while the pivot arms between those pivot arms would provide only the corresponding stop surfaces. If now the turnstile is always rotated by 180 ° when changing cans, an actuating device is accessible from a single point, so that the operation of the same is simplified.
  • the holding elements and the associated actuating element are arranged in the radial end region of a corresponding rotary arm in order to ensure the above-mentioned accessibility.
  • the holding elements are movably mounted around a respective pivot bearing of a rotary arm.
  • the respective rotary bearings it is conceivable, for example, for the respective rotary bearings to have corresponding axes of rotation which run vertically.
  • the holding elements can be tilted or rotated in this case in the horizontal direction about the associated axes, so that a closing or opening of the holding elements is made possible by a simple mechanism.
  • the actuating device comprises an actuating element with the aid of which a force can be transmitted to at least one holding element, by means of which it can be moved between its open position and its closed position.
  • the actuating element may in this case be designed, for example, as a lever to be operated manually.
  • cables, gears or other power transmission mechanisms are conceivable, with the help of which the necessary movement of the holding elements can be achieved.
  • the actuating element is in operative connection with at least one retaining element via a lever device.
  • the holding elements can thus be moved in principle from any point, as long as they are connected via corresponding coupling members, such as the said lever devices, be in operative connection with the actuator.
  • the lever means may be installed such that a tilting or rotational movement of the actuating element can be converted into a corresponding, usually linear movement of the retaining element.
  • the actuating device has a sliding element with the aid of which a movement of the actuating element to the lever device and from the lever device to the retaining element is transferable.
  • the sliding element, z. B. in the form of a sliding block, for example, can be performed on or in an associated guide.
  • the actuating device With the sliding element, the actuating device finally has a movable on a predetermined path intermediate element, in turn, the one or more holding element (s) and a corresponding actuator can be connected.
  • the sliding element thus prevents the retaining element can be brought into a position which would oppose the desired fixation of a pot.
  • frictional forces existing by the sliding element are kept as low as possible during the movement of the holding element.
  • the lever device has a dead center, which can be overcome by moving the actuating element. If, for example, by a correspondingly fixed jug, a force exerted on the retaining element before the dead center is overcome, the force causes an opening of the retaining element. However, if the dead center is overcome, the said force causes the holding element to be moved in the direction of its closed position or held there. Inadvertent opening of the retaining element is excluded in this case.
  • the actuating device comprises a foot pedal with the aid of which the retaining element can be moved between its open position and its closed position.
  • the actuator can in this case easily by the operator of the spinning preparation machine be actuated, the necessary effort can be easily generated by the foot control.
  • the foot pedal can z. B. by said lever means with the or the holding element (s) to be connected to ensure the necessary force transmission.
  • the actuating device comprises a drive unit which can be activated, in particular by means of a control device, for example in the form of a pneumatic cylinder, by means of which the retaining element can be moved between its open position and its closed position.
  • the holding elements can be moved automatically in this case between its open and its closed position, the operation can be done depending on the parameters of the spinning preparation machine. If this signals, for example, that the cans placed at the filling positions are sufficiently filled, the command from the control unit to the drive unit can be made to set the can changer in motion to remove the full cans and to provide the filling positions with empty cans.
  • the actuating device comprises a sensor, for example in the form of a contact sensor, for monitoring the position of the holding element.
  • a sensor for example in the form of a contact sensor
  • contact sensors are conceivable which monitor a contact between a movable section of the holding element to be monitored and a correspondingly rigid counterpart, for example the rotating arm of a turnstile.
  • the associated control unit may finally be programmed so that a movement of the can changer is only possible if the corresponding sensor signals that the holding element is in its closed position. A movement of cans without prior fixation is thereby reliably prevented.
  • the can changer according to the invention with a safety device which prevents or only permits unintentional rotation of the can changer in the case in which one or more of the can stands in the area of can catching devices empty (ie without jug) is. In this way it can be prevented that there is injury, in particular bruising, of an operator who is staying during the change process in the area of one of the lack of can accessible can stands.
  • a possible embodiment provides in this case to equip the can changer with one or more sensors, which detects the presence of a pot in the region of the respective Canengreif wornen. If the respective sensor detects a lack of one or more cans, the can changer is prevented from pending movement, ie, movement thereof is prevented.
  • the can changer is released again and can be moved again if necessary, for example rotated.
  • the can changer or the textile machine controlling it can additionally be equipped with a switching element (for example a pressure or toggle switch) whose actuation independently controls a movement of the can changer allowed by the signals of the sensor (s). It would also be conceivable to allow the movement not only manually (for example, by decoupling the can changer from a corresponding drive unit or by ignoring the respective sensor signal), but to actively initiate a movement by actuating the switching element.
  • the switching element for example, with the drive device of the can changer or an intermediate control and / or regulating unit, coupled, so that an actuation of the switching element would cause an actuation of the drive device and thus a movement of the can changer.
  • the actuator may also be present independently of the above-mentioned sensor to generally allow operator-initiated movement of the can changer.
  • a method for changing cans on a spinning preparation machine preferably a line, carding machine or comber, proposed by means of a can changer, with which the cans are spent during the can change between a first position and a second position.
  • the inventive method provides that prior to the can change two cans are fixed by means of a common actuating element with respect to the can changer.
  • the operating cost of the can changer significantly reduced, preferably a can changer is used with one or more of the features described above.
  • FIG. 1 schematically shows a Doppelkopfumble in the side view.
  • a fiber composite 17 is removed from each of a plurality of so-called feed cans 16 and fed to the respective drafting system 18, the individual drafting systems 18 of the double-head section being arranged one behind the other with a view of the drawing plane.
  • This also applies to the original cans 16, as per drafting system 18 at least one row of feed cans 16 is present.
  • the drafting system 18 is usually made of three or more pairs of rollers 19, each comprising a lower roller and a top roller and cause by different speeds a delay and thus a homogenization of the fiber composite 17.
  • the drawn fiber material 20 is finally fed by means of a pair of calender rollers 21 to a rotating storage tray 22 and placed in an empty can 1 by this loop.
  • FIG. 2 is a plan view of the output range of a corresponding route shown, wherein the portion of the route, which contains the tray 22 and the tray plates 22 itself are indicated by a dashed line only to allow the view of the underlying areas.
  • the exit area can have a lower platform 23 which is only a few centimeters high, on which four empty cans 1 are placed, the area on which the left cans 1 were parked representing the empty can places.
  • the cans 1 parked to the right are located in the region of the filling places below the storage plates 22 of the double-head section.
  • an inventive can changer is provided.
  • FIGS. 3 to 8 A particularly advantageous embodiment of the can changer according to the invention is in the FIGS. 3 to 8 shown.
  • the illustration of the associated components of the spinning preparation machine (for example the storage tray 22) has been omitted for reasons of clarity. Basically, however, that also in this case, the filling stations are arranged on the right side of said figures and on the left side of the empty can places.
  • FIG. 3 now shows the position of the can changer, which he occupies, for example, at the beginning of the operation of the spinning preparation machine to which no filing of the fiber material 20 takes place.
  • the can changer has a turnstile 5 rotatable about an axis of rotation 7 with four radially extending rotating arms 6.
  • the rotating arms 6 may have a height of a few centimeters and are preferably arranged just above a platform 23 or the ground to give the cans 1 during the can changing operation described below a guide.
  • the shown storage area 26, which preferably has a two-dimensional extent, in the underlying foundation below the hub 5 (for example, a hall floor) flush, so that a smooth transition from the foundation to the shelf 26 is created.
  • a separate platform 23 can be dispensed with (however, as an alternative, a flush transition between the foundation and platform 23 is also possible). Such a transition finally allows a displacement of the cans 1 from the foundation to the shelf 26 or the platform 23 and thus in the can changer and vice versa, without annoying edges or slopes would have to be overcome.
  • FIG. 3 shows the holding elements 3 in its open position, in which the cans 1 can be pushed into the region of the can-gripping devices formed from stop surfaces 2 and holding elements 3.

  • the sliding element 15 is in turn connected by means of two lever devices 10 to two holding elements 3 arranged on both sides of the actuating device 4, so that two holding elements 3 are jointly connected between their respective open position (FIG. FIG. 9 ) and their corresponding closed position ( FIG. 11 ) can be moved.
  • FIGS. 3 to 8 show Figures 12 and 13 a partial section through a rotary arm 6 of a can changer according to the invention. From this it is apparent a possibility to move the already mentioned sliding element 15 such that the holding elements 3 can be moved between their open and their closed position (the hierein and also in FIG. 14 Of course, shown actuator 4 is also on the in the FIGS. 3 to 8 shown can changer transferable).
