Definitions
- the invention relates to a winding machine for winding a continuously starting thread according to the preamble of claim 1 and a method for winding a continuously starting thread according to the preamble of claim 10.
- Such a winding machine and method for winding a thread is known from DE 38 26 130.
- the thread is guided back and forth on a guide ruler with a leading edge by means of a wing traversing device.
- a higher mass distribution of the thread occurs in the area of the stroke reversal, which leads to increased edge formation at the bobbin ends.
- the position of the guide ruler can be changed in such a way that the stroke length of the traversing stroke can be varied.
- the problem arises that the thread with a shorter traversing stroke in the stroke reversal area for a time without guidance.
- the displacement of the guide ruler means that the thread from the leading wing falls off the wing tip before the stroke reversal point is reached.
- the thread is now without a guide until the return wing reaches the thread.
- Such guideless states of the thread lead to an irregular Depositing the thread on the bobbin.
- the thread With wing traversing, the thread is laid along a leading edge within the traversing stroke in order to make the traversing speed more uniform.
- the leading edge is curved in such a way that the thread on the wing is deposited on the spool surface at a predetermined traversing speed.
- the mass distribution of the thread on the bobbin depends on the traversing speed set in each case.
- any profile of the traversing speed can be set within the traversing stroke by changing the shape of the leading edge.
- the particular advantage of the invention is that cylindrical coils with a uniform coil surface can be wound.
- the coils also have a hardness that is uniform over the entire surface of the coil.
- the shape of the leading edge is changed in the central region of the traversing stroke.
- the change in shape of the leading edge is formed by a plurality of guiding rulers arranged in parallel planes, each having a partial leading edge.
- the shape of the leading edge can be changed transversely to the thread guide by a relative movement of the guide rulers.
- the particular advantage of this arrangement is that the mass distribution can be influenced specifically in certain areas of the coil surface independently of other areas of the coil surface.
- the leading edge is formed by overlapping the partial leading edges. Here, the overlap areas always have a continuous transition, so that the thread does not experience any irregularity during the guiding along the leading edge.
- the design of the winding machine according to claim 4 has the advantage that the mass distribution in one half of the coil can be influenced independently of the other half of the coil. This is particularly advantageous, in addition to influencing the mass distribution of the thread, influencing the guiding speed of the thread towards the bobbin end. It is advantageous here if the thread is brought to the reversal point of the stroke at a slower traversing speed, but is then moved away from the bobbin edge again at an increased traversing speed. With this measure, the so-called strikers can be avoided.
- the development according to claim 5 provides that the guidelines are connected to each other in such a way that a common adjustment to change the shape of the leading edge is required. A time-programmed control of the change in shape of the leading edge can thus be carried out. In addition, the essential shape change is achieved in this arrangement in the central region of the traversing stroke.
- Another advantageous embodiment of the on dishwasher provides that the guide lines arranged in parallel planes extend over the entire distance of the traversing stroke.
- the advantage here is that the thread is guided on a conventionally positioned guide ruler. Only in order to even out the mass distribution of the thread, in particular in the central region of the traversing stroke, is a guide ruler arranged in parallel being moved transversely to the thread guide in such a way that the thread is guided on the partial guide edge of the moving guide ruler. Since the guiding rulers extend with their partial guide edges over the entire distance of the traversing stroke, the stroke ends can also be influenced in such a way that the stroke is shortened.
- the development according to claim 8 provides that at least one of the guide rails extends over the entire distance of the traversing stroke and that another of the guide rails is designed to be movable transversely to the thread guide.
- a simple construction is thus realized, in order to be able to carry out, in particular, the balancing of the mass distribution in the middle traversing stroke range at predetermined time intervals.
- the movable guide ruler is moved with its partial guide edge so far into the thread running plane that the partial guide edge of the two rulers intersects at predeterminable transition points.
- the guidance of the thread thus changes in the Transition point from the partial guide edge of a first guide ruler to the partial guide edge of a second guide ruler.
- the overlapping areas ensure a constant course of the thread without a sudden change in direction of the thread.
- the inventive method according to claim 10 is characterized in that the thread can be deposited on the surface of the spool at any guide speed. This enables the mass distribution of the thread on the bobbin surface to be controlled.
- the laws of motion for building a cylindrical coil with straight edges can be optimized in such a way that no so-called strikers occur on the coil edges.
- Fig. 1 is a side view of a dishwasher.
- FIG. 2 Schematic view of a traversing device with two partially overlapping guidelines.
- FIG. 3 +4 Schematic view of a traversing device with two overlapping guidelines.
- a side view of a winding machine is shown.
- the thread 2 runs over a head thread guide 1 to a traversing device.
- the traversing device is designed as wing traversing, as is known from EP 0 114 642 and described in detail there.
- the wing traversing device has the rotors 22 and 23, a wing 7 being arranged on the rotor 22 and a wing 6 being arranged on the rotor 23.
- the rotors 22 and 23 are arranged such that the vanes 6 and 7 rotate in two closely adjacent, mutually parallel planes of rotation.
- the rotors are driven in opposite directions by means of a traversing drive.
- a guide edge 8 is formed on a guide ruler 10.
- a pressure roller 4 is rotatably mounted on another rocker 5 in the machine frame 19.
- the pressure roller 4 rests on the spool surface of the spool 3 with a predetermined contact pressure.
- the coil 3 is formed on a sleeve 15.
- the sleeve 15 is clamped on a winding spindle 16.
- the winding spindle 16 is driven by a spindle motor (not shown).
- the spindle speed is regulated in such a way that the peripheral speed of the coil remains constant during winding. For this purpose, the speed of the pressure roller is measured.
- the thread 2 is supplied without interruption at a constant speed.
- the thread 2 is first passed through the head thread guide 1, which forms the tip of the traversing triangle.
- the thread then enters the wing traversing device.
- the wings 6 and 7, which are driven by the rotors 22 and 23, rotate in different directions of rotation such that the thread 2 is guided on the leading edge 8 of the guide ruler 10, one wing taking over the guidance in one direction and then under the ruler dives while the other wing takes the lead in the other direction and then dips under the ruler.
- the thread on the pressure roller 4 is deflected at more than 90 ° and then wound on the bobbin 3.
- the thread 2 is guided on the partial guide edge 8.1 of a guide ruler 11 and on the partial guide edge 8.2 of a guide ruler 10.
- the guidelines 10 and 11 are arranged in parallel planes to each other.
- the guide rulers 10 and 11 are each fastened to a rotary joint 9.1 and 9.2.
- the guide rulers 10 and 11 overlap in such a way that there is a constant transition between the partial guide edges 8.1 and 8.2.
- the guide lines 10 and 11 are each connected to a pin 12 via a link guide 13.1 and 13.2.
- the pin 12 is movably mounted and coupled to a linear drive 14, so that the pin 12 can be moved substantially perpendicular to the thread guide.
- the shape of the leading edge can be changed in that the pin 12 can be moved between two end stops. Due to the essentially transverse movement of the pin, the guide rulers 10 and 11 are moved relative to one another in such a way that the partial guide edges 8.1 and 8.2 shift essentially perpendicular to the thread running direction.
- the leading edge which is decisive for the traversal is composed of the two partial leading edges 8.1 and 8.2.
- the leading edge can have any shape between the embodiment shown and the Take dashed course of the leading edge in Fig. 1.
- the area of overlap of the partial guide edges 8.1 and 8.2 is designed such that a constant transition between the guide edges 8.1 and 8.2 is ensured in each position of the guide rulers 10 and 11.
- FIG. 3 and 4 show another embodiment of the winding machine according to the invention with a traversing device with a variable leading edge.
- the two guidelines 20 and 21 are arranged in parallel planes to each other.
- the guide ruler 20 has the partial guide edge 8.3.
- the leading edge 8.4 is formed on the guide ruler 21.
- the guide ruler 21 is movably supported relative to the guide ruler 20 and is coupled to a linear drive 14. By means of the linear drive 14, the guide ruler 21 can be displaced in the direction of movement 17 essentially perpendicular to the thread guide and parallel to the guide ruler 10.
- the thread 2 is guided back and forth within the traversing stroke by means of the wings 6 and 7 of the wing traversing from FIG. 1.
- FIG. 3 shows the situation in which the guide ruler 21 is displaced such that the partial guide edges 8.3 and 8.4 do not overlap.
- the thread 2 is only guided on the partial guide edge 8.3 of the guide 20.
- This shape of the leading edge is advantageously such that the traversing speed is reduced in the central region of the traversing stroke compared to the end regions. This increases the mass distribution of the thread on the bobbin to be formed in the central area.
- FIG. 4 shows the situation in which the guide ruler 21 is moved in such a way that the partial guide edges 8.3 and 8.4 each intersect at the intersection points 18.1 and 18.2.
- the thread 2 is within the The traversing stroke is initially guided at the partial guide edge 8.3 of the guide 20.
- the partial guide edge 8.4 of the guide ruler 21 takes over the guidance of the thread until the guide edge 8.4 again dips below the guide edge 8.3 at the intersection 18.2.
- the shape of the leading edge within the traversing stroke is advantageously formed in such a way that the traversing speed is essentially expensive over the entire traversing stroke.
- the combination of the partial guide edge 8.3 and 8.4 causes the thread 2 to be guided essentially with the same guide radius of the wing 6 or the wing 7. Since the guide ruler 21 dips with its partial guide edge 8.4 only in the middle of the traversing stroke in the thread course, the transfer points of the thread between the wings remain unchanged. The traversing stroke is therefore constant during the entire winding.
- the movable guide ruler extends over the entire distance of the traversing stroke and thus also leads to a change in the transfer points in the reversal area of the thread.
- This arrangement is advantageous in order to simultaneously influence the placement of the thread in the bobbin ends.
- the length of the traversing stroke can also be varied.
- both the guide ruler 20 and the guide ruler 21 are designed to be movable. This makes the shape of the leading edge very flexible, which leads to a variety of thread trays.
- the invention In the dishwasher, it is not limited to wing traversing devices, or wing traversing is also detected in which the thread is laid over a traversing stroke by means of a plurality of wings arranged one behind the other. It makes sense that the shape of the leading edge is changed by several parallel and successive rulers.
