Definitions

  • the present invention relates to a can changer for a spinning preparation machine, preferably for a draw frame, carding machine or comber, for moving spinning cans, the can changer comprising at least one first driver and a second driver upstream of the first driver in a predetermined transport direction of the spinning cans, the first The driver and the second driver are mounted on a movably guided support structure of the can changer, the support structure together with the first driver and the second driver using a drive in the transport direction mentioned from a first position to a second position and from there back to the first Position are movable, the drivers are designed to be able to move a spinning can in the transport direction during the movement from the first position to the second position, and wherein at least the first driver is movable on the supporting structure is stored in such a way that it can move relative to the supporting structure from a basic position.
  • a spinning preparation machine preferably in the form of a draw frame, card or combing machine, and a method for changing a spinning can on a spinning preparation machine with the aid of a can changer
  • the can changer comprising at least a first driver and a second driver upstream of the first driver in a predetermined transport direction , wherein the first driver and the second driver are mounted on a movably guided support structure of the can changer, the support structure together with the first driver and the second driver in the mentioned transport direction with the aid of a drive from a first position are moved into a second position and from there back into the first position, the drivers moving a spinning can in the transport direction during the movement from the first position to the second position, and wherein at least the first driver is movably mounted on the support structure, that it can be moved relative to the supporting structure from a basic position.
  • Generic can changers are known in the prior art. They are used to move spinning cans during a change process. Spinning cans are moved from a waiting position to a filling position of the spinning preparation machine. As a rule, the spinning preparation machine has a sliver tray in the area of the filling position, with the aid of which a sliver is deposited in a spinning can.
  • the sliver is, for example in the case of a draw frame, a sliver that has been distorted by a drafting device of the draw frame.
  • the spinning preparation machine can also have several waiting positions and / or filling positions. This is the case, for example, with so-called double-head draw frames, in which two drafting systems are arranged next to one another. Each drafting system is assigned a filling position with a corresponding band storage in the form of a turntable, which in turn is supplied with a sliver by its own drafting system.
  • the sliver can which is currently in the filling position, has been filled to a defined degree with the sliver, it is necessary to remove the filled sliver can from the filling position and at the same time to move an empty sliver can from the waiting position to the filling position ,
  • the object of the present invention is to propose a can changer which has a corresponding displacement of filled and empty Spinning cans causes and takes up a relatively small amount of space.
  • the can changer according to the invention now comprises a first driver and a second driver, both drivers being designed to displace a spinning can each time the respective driver is moved together with the supporting structure to which it is attached.
  • the support structure comprises, for example, a slide, preferably displaceable in the horizontal direction, on which the first and the second driver are mounted. Both drivers are preferably pivotable about a pivot axis, the pivot axes preferably running vertically.
  • the carrier is an empty spinning can in front of the first carrier and a filled can in front of the second carrier, a movement of the support structure from a first position to a second position causes a movement of both carriers and thus a movement of the spinning cans mentioned the transport direction mentioned.
  • the direction of transport is, moreover, the direction of movement of an empty spinning can from a designated waiting position to a defined filling position.
  • the empty spinning can can be moved by the first carrier from the waiting position to the filling position, the first carrier moving from its first position to its second Position moved.
  • the full spinning can is moved by the second driver from the filling position to a removal position, which is preferably located outside the spinning preparation machine. This is done by moving the second driver from its first position to its second position.
  • the support structure is moved again into said first position, in which the two drivers also each take their first position.
  • the first driver can move back into its first position without risk of collision with a spinning can, since at this point in time there is no spinning can at the waiting position mentioned.
  • the second driver in the area of the filling position has to be moved past the previously moved empty spinning can without moving the spinning can.
  • the second driver can be moved relative to the support structure.
  • the second driver is preferably mounted on the support structure so as to be pivotable about a pivot axis. If the support structure is now moved from its second position back to the first position counter to the transport direction, the second driver also moves from its second position to the first position. Due to the relative mobility between the second driver and the support structure, the latter can avoid the spinning can that is currently at the filling position during its movement. The second driver can thus be moved past the spinning can mentioned. In this case, the second driver and thus also the support structure must be moved into a third position, which, viewed in the direction of transport, are each in front of the respective first position.
  • the support structure In order to enable this movement of the second driver, the support structure must be moved correspondingly far against the transport direction. This in turn would have the consequence that the first driver would also be together would be moved with the support structure to a third position, in which it is located in the direction of transport before its first position. In this case, however, the first driver would have an additional space requirement in the opposite direction of transport.
  • the first driver can first be moved from its second position against the transport direction into a third position before it returns to its first position.
  • the can changer also comprises a stop, which is placed in such a way that the first driver comes into contact with the stop when it moves into the third position and is thereby moved relative to the supporting structure.
  • the stop thus represents a limitation for the movement of the first driver, which means that the first driver can move less far against the direction of transport than if the stop were not present. As a result, the distance that the first driver travels between the individual positions in the transport direction during its movement is reduced compared to the case in which there would be no stop.
  • the stop comprises one or more components which, for example, project upward from a base of the can changer. If the first driver now moves from its second position towards its third position, the first driver comes into contact with the stop after a certain movement and is thereby moved relative to the supporting structure.
  • the stop should be arranged in such a way that it comes into contact with that third of the first driver that is furthest away from the support structure, in particular from a pivot axis of the first driver.
  • the first driver is mounted on the support structure via a pivot axis in such a way that it is pivoted about it relative to the carrier when it comes into contact with the stop.
  • the support structure is in this case mounted on a guide, along which the support structure is moved from its second position against the transport direction into the third position. During this movement, the first driver comes into contact with the stop. From this point in time, the first driver is pivoted about the pivot axis until the support structure has reached its third position.
  • the support structure is then moved back to its first position (with the movement taking place in the transport direction), the first driver being pivoted in a pivoting direction opposite to the pivoting direction in which the first driver is pivoted when the support structure is moved from its second Position is moved to its third position.
  • the first driver is first moved in a first direction and then in an opposite second direction, preferably pivoted.
  • the can changer comprises a floor plan, the first driver being in a plan view of the can changer in each of its positions within the floor plan or protruding horizontally by a maximum of 20 cm, preferably by a maximum of 10 cm ,
  • the floor plan is the boundary surface that the can changer occupies in a top view when the two drivers are each in their first position.
  • the stop now ensures that the first driver is always within the above-mentioned floor plan or that it only towers over the above-mentioned maximum amount.
  • the space requirement of the can changer becomes hereby reduced compared to an identically designed can changer, in which there is no corresponding stop.
  • the stop is part of a base of the can changer or is attached to it.
  • the can changer preferably comprises a base area in the form of one or more plate-shaped surface sections, by means of which it can be placed on a base, for example a hall floor of a spinning mill.
  • the stop is, for example, an increase in the base area, the amount of which is dimensioned such that the first driver can come into contact with the stop as described above.
  • the stop is preferably arranged in the transport direction before the filling position. Furthermore, the stop should be designed as a stationary and rigid unit.
  • the first driver in its third position is pivoted further than its basic position than in its first and / or second position.
  • the first driver always assumes the same position with respect to the support structure when it moves from the first position into the second position. If the first driver is finally moved from the second position into its first position and from there into its third position, it is pivoted about the pivot axis.
  • the pivot angle by which the first driver is pivoted is preferably greatest when the first driver is in its third position.
  • the basic position of the first driver is moreover the position relative to the supporting structure which the first driver assumes when it is in its first position.
  • first driver and the second driver each have a contact section for contacting a spinning can.
  • the contact section can be a rotatable roller, for example, which is located at one end of the respective driver.
  • the drivers can be designed as driver arms, the respective first end of which comprises the contact section and the respective second end of which is mounted on the support structure.
  • the contact section is preferably arranged at the end of the corresponding driver facing away from the support structure.
  • the contact sections of the two drivers are always at a certain distance from one another.
  • the minimum distance between the two contact sections is preferably the smallest when the first driver and the second driver are each in their third position. It is also advantageous if the distance mentioned remains constant during the movement of the two drivers from their respective first to their respective second position.
  • the change in the distance is preferably brought about in that the first driver is moved, in particular pivoted, in the direction of the second driver when the support structure is moved into its third position.
  • the support structure can be moved back and forth between the individual positions with the aid of the drive mentioned, which is preferably part of the can changer, along a, preferably linear, guide.
  • the guide can, for example, comprise a guide rail in which the support structure is movably mounted in the horizontal direction.
  • the movement can in turn be carried out with the aid of a belt or chain drive, the chain or belt being connected to the drive (for example an electric motor).
  • the drive for example an electric motor
  • the second driver is also movably mounted on the support structure in such a way that, starting from a basic position, it is movable relative to the support structure. Storage can over in each case a pivot axis or a guide take place, via which the respective drivers can be moved relative to the support structure.
  • both the first driver and the second driver should be connected to at least one energy store, the energy store exerting a force on the respective driver, which ensures that the respective driver is in its basic position when there is no additional force on it is exercised.
  • the energy accumulator is preferably a spring element, for example in the form of a tension or compression spring or a compressed air cylinder. The energy accumulator ensures that the respective driver is in its first position.
  • the first driver can be moved against the force of the energy accumulator when it comes into contact with the stop and the support structure continues to move against the transport direction.
  • the second driver can be moved against the force of the energy store if it comes into contact with a spinning can in the region of the filling position while the support structure moves from the second position against the transport direction.
  • the invention also relates to a spinning preparation machine, preferably in the form of a draw frame, card or combing machine, the spinning preparation machine being characterized in that it comprises one or more jug changers arranged adjacent to one another in accordance with the previous or following description.
  • the spinning preparation machine is preferably designed as a double-head draw frame, which comprises two adjacent drafting systems and two belt depositors (for example in the form of depositing plates known from the prior art), one strip depositing device being assigned to a drafting arrangement.
  • Each filling position is preferably assigned its own support structure, which in each case comprises at least a first driver and a second driver.
  • the can changer comprises at least a first and a second driver, the two drivers being moved from a first position to a second position during the can changing process.
  • the first driver moves an empty spinning can from a waiting position and in the transport direction mentioned to a filling position.
  • a filled jug is moved from the filling position to a removal position in the transport direction.
  • the displacement of the spinning cans and / or the movement of the first and second driver as well as the support structure should take place in a linear direction.
  • the two drivers are also moved at the same time, whereby they can in particular have been fastened to a lonely support structure which is correspondingly moved with the aid of a drive.
  • a lonely support structure which is correspondingly moved with the aid of a drive.
  • At least the first driver after moving a spinning can starting from its second position against the direction of transport is first moved to a third position and thereby comes into contact with a stop. This leads to the first driver being moved relative to the supporting structure.
  • the stop causes the first driver to move, in particular pivot, from the contact with the stop relative to the support structure.
  • the relative position of the first driver with respect to the support structure changes as soon as the first driver with the Stop comes into contact. From this moment on, the linear movement of the first driver is preferably converted into a pivoting movement, so that the first driver is pivoted relative to the support structure.
  • the section of the first driver that comes into contact with the stop is no longer moved against the direction of transport from the contact with the stop, so that the space requirement in this direction is less than in a comparable spinning preparation machine in which there is no stop ,
  • the first driver is pivoted relative to the carrier about a pivot axis when it comes into contact with the stop.
  • the pivoting process preferably takes place about a vertically running pivot axis.
  • the basic position is preferably achieved by an energy accumulator which is connected to the supporting structure. After taking the basic position, an empty spinning can again be moved into the waiting position area and then moved into the filling position area with the help of the first driver.
  • the first position of the support structure lies, moreover, in the direction of transport between its second position and its third position. It is particularly advantageous if the first driver is moved, preferably pivoted, from its second position to its third position in a first direction of movement in the course of its movement. The movement is preferably carried out with reference to the support structure in the direction of transport. If the first driver is moved, preferably pivoted, from its third position into its first position in a second direction of movement with respect to the support structure in the course of its movement, this movement takes place in a direction opposite to the first direction of movement.
  • the first driver is moved, preferably pivoted, against a force of an energy accumulator in the first direction of movement and with the force of the energy accumulator in the second direction of movement.
  • the energy accumulator thus ensures that the first driver always assumes its basic position when it is not in contact with the stop.
  • pivot axis is moved against the transport direction and in particular in the horizontal direction when the first driver is moved from its second position, preferably via its first position, to its third position.
  • the pivot axis is preferably part of the support structure and is moved with it when the support structure moves from the second position to the third position.
  • Figure 1 shows a section of a spinning preparation machine according to the invention in the form of a draw frame.
  • the route includes, among others, in Figure 1 Components not shown, at least one drafting device 2 with a plurality of drafting device rollers 17, with the aid of which a sliver 15 fed to the drafting device 2 can be made uniform in terms of its thickness.
  • the sliver 15 is deposited in a spinning can 8 arranged below the drafting device 2 via a depositing device, which is preferably provided as a depositing plate 18.
  • This spinning can 8 is in a filling position of a can changer 1 during the depositing process.
  • FIGS Figures 2 to 6 The top view of a corresponding can changer 1 is, for example, in FIGS Figures 2 to 6 shown (the drafting system 2 and the storage plate 18 are not shown in these figures for reasons of clarity).
  • the can changer 1 comprises a first driver 3 and a second driver 5, both of which are mounted on a common support structure 6.
  • the support structure 6 is in turn mounted in a guide 12 and can be moved back and forth along the guide 12 with the aid of a drive.
  • Figure 2 now shows a state in which the in Figure 1 Spinning can 8 shown on its filling position up to a predetermined level with the sliver 15 was filled from the drafting system 2. Furthermore, an empty spinning can 8 is placed in the can changer 1, which is in a waiting position, which is located in a predetermined transport direction T before said filling position.
  • the support structure 6 must now be moved back to its first position.
  • the support structure 6, as in Figure 4 shown moved against the transport direction T.
  • the second driver 5 is mounted on the support structure 6 via a pivot axis 10, it can deflect when it passes the spinning can 8 located on the filling position, so that this spinning can 8 does not have to be moved.
  • the second driver 5 preferably has a contact section 11 in the form of a roller (the first driver 3 can of course also have a corresponding contact section 11).
  • an energy accumulator 4 for example a tension spring
  • the invention now provides a stop 9 with which the first driver 3 comes into contact when the support structure 6 moves from its second position into its third position.
  • the third position of the support structure 6 is in Figure 5 shown.
  • the first driver 3 is pivoted in this position relative to the support structure 6 in the transport direction T. This leads to the minimum distance A between the two contact sections 11 of the first driver 3 and the second driver 5 (see Figure 5 ) occupies a minimum amount in the third position of the support structure 6.
  • a new empty spinning can 8 can be pushed to the waiting position, while the spinning can 8 can be filled with fiber sliver 15 in the filling position.
  • a corresponding force accumulator 4 (not shown) is preferably also assigned to the first driver 3.
  • FIG Figures 7 and 8th An alternative embodiment of the can changer 1 according to the invention is shown in FIG Figures 7 and 8th , As a comparison of these figures shows, here the first driver 3 is not pivotally mounted about a pivot axis 10. Rather, the support structure 6 comprises a driver guide 12, in which the first driver 3 can be moved relative to the support structure 6 in the transport direction T and also counter to the transport direction T. That way too can be avoided by the contact of the first driver 3 and the stop 9 that the first driver 3 must be moved against the transport direction T over the floor plan of the can changer 1. The space requirement of the can changer 1 is thus also less in this case than in the case in which there is no stop 9.
