Description

Technical Field

[0001] The invention relates to a winding machine. The winding machine comprises a main shaft. The main shaft can be rotated by an electric motor. A winding sleeve can be arranged on the main shaft, and the winding sleeve is fixed to the main shaft in a non-rotatable manner by suitable fixing means. When the motor drives the winding sleeve via the main shaft, a winding product (especially a tape, a thread, a yarn or a wire) can be wound onto a bobbin. The winding machine comprises a transverse mechanism carrier. The transverse mechanism carrier carries a transverse guide rail, which is used to guide the product to be wound to the winding sleeve. The transverse guide rail moves back and forth in an axial direction of the winding sleeve in a swinging manner and is parallel to the winding sleeve so as to position the winding product on the winding sleeve. The number of rotations of the main shaft is coordinated with the movement pattern and movement speed of the transverse guide rail so as to form a desired winding pattern on the winding sleeve, thereby producing a well-formed bobbin. The winding machine comprises a pressure roller and a machine housing. The pressure roller can also be called a contact roller or a pressure holding roller. The transverse mechanism carrier is supported by the machine housing so as to be rotatable around a pivot axis. The transverse mechanism carrier supports the pressure roller so that it rotates around the rotation axis. The pressure roller is used to establish rolling contact with the outer surface of the winding wound on the winding sleeve. In the contact area between the pressure roller and the outer periphery of the winding, the wound product is positioned and pressed on the winding. The transverse mechanism carrier and the pressure roller are pressed onto the winding by weight (for example, their own weight) and / or the friction reaction force of the actuator and / or the brake device, resisting the movement of the pressure roller as the diameter of the winding increases. During the winding process, when the diameter of the winding increases, the transverse mechanism carrier rotates around the pivot axis.

[0002] Furthermore, the invention relates to a winding device, a transverse mechanism carrier stop device and a method for operating a winding machine. Background Art

[0003] The applicant sells a winding machine "stacoFIL 200XE". In this winding machine, the pressure roller neither contacts the winding sleeve nor the initially established winding on the winding sleeve. On the contrary, at the beginning of the winding process, the transverse mechanism carrier is supported by the stop element. The position of the stop element makes the transverse mechanism carrier located at the starting pivot angle. The purpose of selecting the starting pivot angle is to establish a defined gap (particularly 0.8 mm to 1 mm) between the empty winding sleeve and the pressure roller. The winding process starts in the above-mentioned defined gap so that the first winding is positioned on the winding sleeve, and the pressure roller does not contact the winding sleeve and the first winding wound thereon. In the first stage of the winding process, the gap between the pressure roller and the outer surface of the established winding gradually decreases. When the gap is reduced to zero, the pressure roller contacts the outer surface of the winding. In the second stage of the winding process, the diameter of the winding increases further, and the transverse mechanism carrier is no longer supported by the stop element. Conversely, as the diameter of the winding increases, the transverse mechanism carrier moves away from the stop element and the pivot angle of the transverse mechanism carrier also increases starting from the starting pivot angle.

[0004] In the applicant's " The "stacoFIL 200XE" instruction manual contains instructions on how to position the stop element for limiting the starting pivot angle of the transverse mechanism carrier. The stop element is implemented as a screw that is tightened on a bracket held by the machine housing. The screw includes an end with a buffer element, on which the transverse mechanism carrier is supported in the first winding process stage. In order to adjust the position of the stop element and adjust the starting pivot angle, the operator must have access to the screw, which is indeed difficult to access (this is also the case in other prior art devices / winding machines) and must have access to the front side of the screw in order to be able to manually turn the screw (i.e. change the screw-in angle of the screw so that it enters the desired new position) and move the front end of the screw in a linear direction parallel to the front side of the machine housing. Summary of the invention

[0005] The object of the present invention is to provide a winding machine which is improved in particular in the following aspects:

[0006] - simplify operations, and / or

[0007] - operational safety, and / or

[0008] - the number of components, and / or

[0009] -Compact design.

[0010] Furthermore, it is an object of the present invention to propose an improved method for operating a winding machine and an improved winding device.

[0011] Solution

[0012] According to the invention, the object of the invention is solved by the features of the independent claim. Further preferred embodiments according to the invention are described in the dependent claims.

[0013] The object of the present invention is solved by a winding machine comprising a motor actuated by a switching mechanism. The brake device applies a braking torque around the pivot axis to the transverse mechanism carrier. The present invention proposes that the switching mechanism for activating the motor of the drive spindle is actuated by the brake device. The switching mechanism can be the only switching mechanism for actuating the motor, or at least one additional switching mechanism can also be present. At the beginning of the winding process, the brake device is released. In this case, the actuation of the release brake device can be used to automatically actuate the switching mechanism for the motor. Since the actuation of the motor when the brake device is not released can be avoided, the safety of this embodiment is improved. In any process stage of the winding machine or device, in particular after replacing the fully wound winding sleeve (bobbin) with a new winding sleeve, and / or after a fault occurs during the winding process, such as a yarn break or an undesirable winding is corrected, the automatic actuation of the motor after the brake device is released is beneficial. In the case where the winding machine needs to be started, such as after the first installation of the machine or device, or after maintenance work, this device is particularly desirable. However, the brake device can also be used in a multifunctional manner, thereby simplifying the design of the winding machine and making its structure more compact. For example, a first actuation mode may result in a change in the braking torque of the brake device. In a second actuation mode (different from the first actuation mode), the application of the brake device is not changed but remains unchanged (in particular, the brake remains released). In the second actuation mode, only the switching mechanism may be actuated. The brake device may include a manual actuation element that can be actuated by an operator. When actuated by the operator, the element may move along different degrees of freedom or different parts of a linear, curved or pivoting motion path of the respective actuation mode.

[0014] The brake device can be actuated in various ways. In one embodiment of the invention, the brake device is a manually actuable brake device. In one embodiment, the manual brake device includes a manually actuated element. In this case, the switch mechanism can sense the position of the manually actuated element. For this purpose, at least one sensor element is preferably provided. The position of the manually actuated element can be an absolute position. However, in another embodiment of the invention, the switch mechanism senses the position of the manually actuated element relative to the transverse mechanism carrier.

[0015] For example, the switch mechanism may comprise two sensor elements. One of the sensor elements may be arranged in or on the manual actuation element, while the other of the sensor elements may be appropriately positioned in or on the transverse mechanism carrier. The sensor elements are arranged so that the distance between the sensor elements changes when the manual actuation element moves. The two sensor elements may form a mechanical switch, and the switch state changes when a specific distance between the sensor elements is reached or exceeded. The sensor element may be a sensor that continuously measures the distance and / or a sensor based on any other sensor principle. The displacement measured by the sensor element may be a translational displacement, a rotational displacement or any other displacement, for example, along a curved path.

[0016] In one embodiment, the manual actuation element is a manual actuation lever.

[0017] The switch mechanism may include any type of sensor for sensing the relative position of the manual actuating element and the transverse mechanism carrier. According to a simple embodiment of the invention, the sensor is a Hall sensor. The Hall sensor is based on the Hall sensor effect and can detect the presence and magnitude of a magnetic field. The output voltage of the Hall sensor is proportional to the strength of the detected magnetic field. There are Hall sensors on the market for detecting displacement or rotation angle, where the Hall sensor can be combined with threshold detection and used as a binary switch. If a Hall sensor is used, the manual actuating element or the transverse mechanism carrier should hold a permanent magnet. If the permanent magnet is located in or on the manual actuating element, the transverse mechanism carrier includes a sensor element for sensing the magnetic field generated by the permanent magnet. Another alternative is that the magnet can of course be installed in or on the transverse mechanism carrier, and the manual actuating element carries the sensor element.

[0018] However, any type of sensor including an inductive sensor may be used instead of the Hall sensor.

[0019] The signal of the sensor can be processed in a continuous manner or in a binary manner, with the two binary switching states being defined by threshold values. In this case, the drive of the motor can be triggered by any value or result of the switch mechanism or the sensor. Thus, the motor can be switched according to any braking torque of the brake device. In one embodiment of the invention, the two functions of the brake device (i.e., providing the braking torque on the one hand and triggering the motor to drive the spindle on the other hand) are separated: the manual actuating element comprises an actuation area defined by the stroke or movement path of the manual actuating element. One embodiment of the invention proposes that the actuation area comprises a first actuation sub-area, in which the position of the manual actuating element is related to the generated braking torque. Thus, in the first actuation sub-area, the operator can determine the required braking torque by / when actuating the manual actuating element. In a second actuation sub-area that does not overlap with the first actuation sub-area, the braking torque is constant and / or zero. In the second actuation sub-area, a change in the position of the manual actuating element switches the switch mechanism, thereby triggering the operation of the motor for driving the spindle.

[0020] A particular aspect of the invention is based on the following discovery: On prior art winding machines, it is cumbersome and time-consuming for the operator to adjust the starting pivot angle of the lateral mechanism carrier. First, in order to make a large adjustment to the starting pivot angle, it may be necessary to rotate the stop screw multiple 360°. In addition, in order to achieve a small change, the operator must carefully operate and control the starting pivot angle, which requires repeatedly changing the rotation angle of the screw and checking the resulting starting pivot angle. The inspection may include measuring the gap between the pressure roller and the outer surface of the winding sleeve. The accuracy of the gap at the beginning of the winding process depends on the operator's carefulness. If operated with caution as required, the working time of one operator per winding machine to adjust the stop screw exceeds 30 seconds. In actual operation, the operator often skips the adjustment process in order to save time. As a result, the stop screw in the same position is used for different winding processes and / or winding sleeves of different diameters. This results in insufficient screw-in angle (screw-in angle) of the stop screw, too small a gap, or even no gap at all. This leads to defects, even damage, and in any case to out-of-roundness of the winding sleeve, which in turn leads to undesirable deviations of the pressure rollers, the carrier of the transverse mechanism and the bearings used to support the pressure rollers. In addition, at the beginning of the winding process, the wound product only covers a partial area of ​​the winding sleeve. If the gap between the pressure roller and the surface of the winding material is too small or even absent, irregular, undesirable deviations of the pressure roller, the machine housing and the associated bearings are inevitable. On the other hand, if the gap is too large due to insufficient screw-in angle of the stop screw, the first winding process stage takes longer than required, so that for a considerable period of time the winding material is wound without any contact pressure from the pressure roller, resulting in an undesirable winding pattern and a significant reduction in the quality of the produced wire bobbins.

[0021] According to the above conclusions, the present invention proposes that the stop element comprises a stop element profile. The stop element profile has at least two stop element profile segments. The stop element profile segments define different starting pivot angles of the transverse mechanism carrier. In this way, the gap between the pressure roller and the winding sleeve and the winding material can be changed conveniently and flexibly.

[0022] According to the invention, the stop element can be supported so as to be movable into different positions. This movement is not a spiral movement like the spiral stop elements known from the prior art. Instead, the movement of the stop element is a translational movement or a rotational movement. In different positions in which the stop element can be moved, different stop element profile segments can be activated in order to determine the corresponding starting pivot angle in said different positions. In this way, a specific starting pivot angle can be set by simple operation.

[0023] By designing one of the stop element profiles, for example two stop element profile segments, different starting pivot angles can be precisely defined. The operator does not have to adjust the spiral stop device used in the prior art winding machine. Instead, the operator only has to move the stop element to different positions to activate the stop element profile segments. According to the invention, activating the stop element profile segment particularly means moving the stop element profile segment to a position in which this particular stop element profile segment defines the starting pivot angle, which is provided by the contact of the stop element profile segment with the mating stop element.

[0024] In the framework of the invention, the stop element profile segment is used to support any counter-stop element connected (directly or indirectly) to the transverse mechanism carrier, so that the contact of the counter-stop element with one of the stop element profile segments defines the starting pivot angle of the transverse mechanism carrier. In one embodiment, the transverse mechanism carrier comprises a counter-stop element, which is supported by one of the stop element profile segments at the beginning of the winding process.

[0025] The stop element profile and the stop element profile segment can have any shape and curvature. In general, the surface normal of at least one stop element profile segment in the contact area with the mating stop element can be inclined with the direction of movement of the mating stop element (and therefore with the contact force applied by the mating stop element). However, in one embodiment of the present invention, the surface normal is parallel to the direction of movement of the mating stop element held by the transverse mechanism carrier. In this case, the direction of movement of the mating stop element can be tangent to the pivot axis of the transverse mechanism carrier at the position of the mating stop element. In this orientation of at least one stop element profile segment, the contact force applied by the mating stop element is completely supported by the normal force of the stop element profile segment, and any tilt may lead to an undesirable downward force. Any downward force generated in the contact area will cause the stop element to deviate from its position, which may require additional fixing forces or fixing mechanisms to ensure that the stop element does not deviate from its position.

[0026] The stop element may be moved by any mechanism, actuator or motor to activate different stop element profile segments.In one embodiment of the invention, the stop element is a manually movable stop element.

[0027] The stop element can have any degree of freedom. For example, the stop element can be moved in a translational degree of freedom to activate different stop element contour segments. However, in a preferred embodiment of the present invention, the stop element is a rotatable stop element of unlimited design form.

[0028] According to one embodiment of the invention, the rotatable stop element comprises a cam disc. The radially outer surface of the cam disc forms a stop element profile having at least two stop element profile segments. In this case, the radii of the at least two stop element profile segments relative to the axis of rotation of the cam disc are different. Using a cam disc to provide the stop element profile is a very simple but reliable solution for providing stop element profile segments.

[0029] In a particular embodiment of the winding machine of the present invention, the stop element comprises a manual operating wheel, which the operator can grasp and turn. In addition, the stop element also comprises the above-mentioned cam disc. The manual operating wheel is connected to the cam disc by an axis so that the cam disc rotates together with the manual operating wheel. In this case, the manual operating wheel and the cam disc can be arranged on different sides of the machine housing. In this case, the axis passes through the machine housing. The axis can be supported in the machine housing or supported by the machine housing. A sliding bearing or a rolling bearing can be provided to support the rotation of the axis. The bearing can be installed in the machine housing. In this case, the manual operating wheel can be arranged on the front side of the winding machine (preferably on the same side as the lateral mechanism carrier, the pressure roller and the main shaft). For this embodiment, the operator can easily access the manual operating wheel. The cam disc is preferably arranged on the back side of the machine housing. Therefore, the operator cannot see the cam disc, and the operator does not have the risk of injury when operating the machine, for example, his / her fingers are caught between the cam disc and the stop element and injured. In addition, the cam disc and / or the matching stop element can also be prevented from interfering with the winding product.

[0030] It is not necessary to fix a specific position of the stop element at which the corresponding stop element profile segment cooperates with the counterpart stop element. However, the specific position can be fixed by any means or measures, such as by friction forces to counteract any movement of the stop element. In one embodiment of the invention, the winding machine comprises a latching device for fixing the position of the stop element.

[0031] The latching device can be implemented as a locking device for preventing any movement of the stop element (under force in the movement direction of the stop element). The locking device can preferably be unlocked by additionally unlocking the locking element.

[0032] However, the latching device can also be a snap-in connection device, which fixes the stop element and prevents it from moving when the force applied in the direction of movement is below a threshold force. When the force applied to the stop element exceeds the threshold, the snap-in connection device automatically leaves the fixed position without any additional measures. The snap-in connection device can include a snap-in spherical object (ball) or a pin, which is pressed into the snap-in groove or recess by a snap-in spring. In this case, the snap-in groove or recess has an inclined edge, which can generate a force component of the force applied by the operator, which force component can counteract the force of the snap-in spring.

[0033] The position of the stop element profile may be linearly related to the movement of the stop element. In the case of a rotating cam disc, the outer radius of the cam disc along the periphery (or at least the corresponding position along the periphery) may increase linearly as a function of the circumferential angle. However, any other shape of the stop element profile and any other dependency may also be used.

[0034] The stop element can be adjusted in sections and steps according to a special stop element contour or continuously.

[0035] In one embodiment of the invention, the stop element or cam disc comprises a position indicator. The position indicator can indicate, for example, the relative distance of the pressure roller to the axis of rotation of the main shaft. In one or more other embodiments, the position indicator can indicate the position of the stop element associated with a winding sleeve of a specific type or outer diameter. According to a non-limiting example, the winding machine can be used for specific winding sleeves with diameters of 38 mm, 40 mm, 42 mm, 45 mm, 47 mm and 49 mm. In this case, the position indicator can indicate the position of the manually operated wheel or cam disc, which defines the clearance required when using the above-mentioned specific winding sleeve diameter.

[0036] The mating stop element may be rigidly coupled and fixed to the transverse mechanism carrier in any manner and design.

[0037] According to one embodiment of the winding machine of the present invention, the winding machine includes a braking device. When the braking device is actuated and in an applied state, the braking torque generated by the braking device supports the transverse mechanism carrier on the machine housing. In this case, the braking device can be actuated by an actuating shaft. The actuating shaft can be supported by the transverse mechanism carrier for rotation. The rotation of the actuating shaft can drive the brake element to rotate, and can increase the contact force between the brake element and the matching brake element held by the machine housing, thereby generating a braking torque. In this case, the actuating shaft can carry or contain the matching brake element. In the simplest case, one end of the actuating shaft constitutes a matching brake element, which is used to support the transverse mechanism carrier on the corresponding brake element profile segment. In this case, the actuating shaft can be used in a multifunctional manner, thereby reducing costs and the design is also very compact.

[0038] Another solution to the purpose of the present invention is a method for operating the above-mentioned winding machine. The method of the present invention is based on the idea of ​​starting the winding process by the actuation of a brake device. The method proposes that the actuation of the brake device is caused by the operation of a manually actuated brake device, in particular by the actuation of a manually actuated element. In one embodiment of the method, a switch mechanism senses the position of the manually actuated element and / or a switch mechanism senses the position of the manually actuated element relative to a transverse mechanism carrier. For example, a manually actuated element implemented as a manually actuated rod can be used. Preferably, according to the method of the present invention, the switch mechanism includes a Hall sensor for sensing the actuation of the brake device. In one embodiment of the method, the manually actuated element includes an actuation area, and the actuation area includes a first actuation sub-area and a second actuation sub-area. In the first actuation sub-area, the position of the manually actuated element is related to the braking torque generated. In the second actuation sub-area, the braking torque is constant and / or zero and will not be changed by the actuation of the manually actuated element. In the second actuation sub-area, the change in the position of the manually actuated element preferably switches the switch mechanism.

[0039] One embodiment of the method comprises the following steps:

[0040] - Pivoting the transverse mechanism carrier about the pivot axis to an alternative pivot angle. Preferably, at the alternative pivot angle, the pressure roller held by the transverse mechanism carrier is at a maximum distance from the main shaft. At the alternative pivot angle, the finished wound bobbin can be removed from the main shaft. At this stage, the drive device for rotating the main shaft is not activated and the main shaft is stationary. In another alternative case, for example after installation of a machine or an equipment, or after maintenance work, there may be no winding sleeve arranged on the main shaft. In this case, the pressure roller may remain at a position close to or at a medium distance from the main shaft. In order to start the winding process, that is, the method of the present invention, the transverse mechanism carrier is pivoted about the pivot axis to the replacement pivot angle.

[0041] -The operator selects a stop element profile segment from at least two stop element profile segments. When making the selection, the operator can use a position indicator on the stop element or on the cam disk. The operator selects the position indicator or the stop element profile segment specifically for a specific winding process or a specific winding sleeve. For different (variable) winding processes or different wound products, the gap at the start of the winding process is different and therefore different stop element profile segments may be required. Alternatively or additionally, the use of winding sleeves of different diameters may require the use of different corresponding stop element profile segments. The operator selects the appropriate stop element profile segment to determine the corresponding required gap.

[0042] - moving the locking element into a position in which the selected locking element contour section becomes active, ie becomes active by contact of the selected locking element contour section with a counter locking element held by the transverse mechanism carrier.

[0043] - Before or after these steps, the operator arranges the winding sleeve on the spindle; in particular, the specific winding sleeve associated with the selected stop element profile segment is selected. In practice, for simpler handling of the machine, the stop element profile segment can be selected to correspond to the winding sleeve.

[0044] The transverse mechanism carrier pivots about the pivot axis from the replacement pivot angle to the starting pivot angle. The starting pivot angle is defined by the stop element, in particular by the contact of a mating stop element held by the transverse mechanism carrier with a selected stop element profile segment. When the transverse mechanism carrier is rotated to the starting pivot angle defined by the stop element profile segment, the pressure roller forms a defined gap with the outer surface of the winding sleeve arranged on the spindle.

[0045] -Then the winding process begins. In the first winding process stage, the transverse mechanism carrier is supported by the stop element. In the first winding process stage, the outer diameter of the winding created on the winding sleeve increases, and the gap between the pressure roller and the outer surface of the winding is reduced to zero. In the subsequent second winding process stage, the outer diameter of the winding increases further (in a continuous manner). The transverse mechanism carrier is no longer supported by the stop element. On the contrary, the transverse mechanism carrier moves away from the stop element, in particular toward the stop element. Therefore, in the first winding process stage, the pressure roller will not apply a contact force to the outer surface of the winding, while in the second winding process stage, the pressure roller will compress the winding and press the wound product to the outer surface of the winding.

[0046] In a specific embodiment of the method of the present invention, the winding process, in particular the first winding process stage and the driving operation of the motor driving the main shaft are initiated by actuating the braking device (see the above description of the manually actuated braking device, the manual actuating element, the switch mechanism for sensing the position of the manual actuating element and the position of the manual actuating element relative to the transverse mechanism carrier, the embodiment of the manual actuating element as a manual actuating rod, the use of a Hall sensor, and the actuating area of ​​the manual actuating element including a first actuating sub-area and a second actuating sub-area).

[0047] It will be appreciated that a winding machine designed according to the invention may be arranged on a winding machine installation having a plurality of winding machines designed according to the invention, for example arranged in series.

[0048] Another solution to the object of the invention is a winding installation comprising a plurality of winding machines which can be operated simultaneously to wind a plurality of reels or bobbins.

[0065] Figure 1 The winding machine 1 is shown in a three-dimensional top view. The winding machine 1 comprises a stationary machine housing 2 for supporting components of the winding machine 1 and comprises in particular frames, struts, housing plates, cover plates and / or decorative elements.

[0066] The transverse mechanism carrier 3 is supported by the machine housing 2 so as to be pivotable about a pivot axis. The transverse mechanism carrier 3 supports a transverse guide 5. The transverse guide 5 guides the wound product to perform an oscillating transverse movement 6 during the winding process.

[0067] The transverse mechanism carrier 3 supports the pressure roller 7 so that it can rotate about an axis of rotation 8 .

[0068] The spindle 9 is driven by a motor (not shown) to rotate about a spindle axis 10, which is oriented parallel to the transverse movement 6 and the pivot axis 4. A winding sleeve 11 is arranged on the spindle 9. The winding sleeve 11 is fixed to the spindle 9 non-rotatably by one of the fixing mechanisms known in the art, in particular a stretching mechanism. The wound product, in particular a wound yarn, a wound thread or a wound tape, is positioned on the outer surface of the winding sleeve 11 by means of the transverse guides 5 and the pressure rollers 7, so that the winding is built up on the winding sleeve 11. Due to the contact forces between the pressure rollers 7 and the outer surface of the winding during the winding process, the pivot angle 12 of the transverse mechanism carrier 3 about the pivot axis 4 increases with increasing winding diameter.

[0069] The winding machine 1 comprises a brake device 13. The brake device 13 comprises a manual actuation element 14, which is implemented here as a manual actuation lever 15. The manual actuation element 14 is fixedly connected to a first end of a brake actuation shaft 16. The second end of the brake actuation shaft 16 is fixedly connected to a brake actuation element 17, which is implemented here as a brake actuation lever 18, at the outer end of which a brake pad 19 is arranged (see Figure 4 ). A manual actuation element 14 is arranged at the front side of the transverse mechanism carrier 3. A brake actuation shaft 16 extends through the transverse mechanism carrier 3, and the transverse mechanism carrier 3 supports the brake actuation shaft 16 so that it rotates about an actuation axis 20. The actuation axis 20 is oriented parallel to the pivot axis 4 and is arranged offset from the pivot axis 4. A brake actuation element 17 is arranged at the rear side of the transverse mechanism carrier 3, between the transverse mechanism carrier 3 and the machine housing 2.

[0070] The machine housing 2 carries a brake ring segment 21. The brake ring segment 21 provides a brake surface 22, which, in the applied state of the brake device 13, comes into frictional contact with the brake pad 19. The operator can cause a rotational movement of the actuation shaft by actuating the manual actuation lever 15, thereby causing a pivoting movement of the brake actuation lever 18. Due to the misalignment of the pivot axis 4 and the actuation axis 20 and / or the misalignment of the center of the cylindrical brake surface 22, pivoting the manual actuation lever 15 from a release position in which the brake pad 19 is not in contact with the brake surface 22 to an applied position in which the brake pad 19 is pressed against the brake surface 22 leads to an actuation of the brake device 13 and the creation of a braking force, thereby leading to the generation of a braking torque.

[0071] The minimum pivot angle 12 of the transverse mechanism carrier 3, i.e. the starting pivot angle 39, is determined by the transverse mechanism carrier stop device 23 (see Figure 2 The transverse mechanism carrier stop device 23 comprises a stop element 24 which can be fixed on the machine housing 2 in a selected operating state and a mating stop element 25 which is held by the transverse mechanism carrier 3. At the starting pivot angle 39, the mating stop element 25 abuts against the stop element 24.

[0072] The locking element 24 is designed as a cam disk 26 (see Figure 3 ). To change the operating state of the cam disc 26, the cam disc 26 can be rotated about the rotation axis 27 of the transverse mechanism carrier stop device 23. The cam disc 26 has a radial outer surface that provides a stop element profile 28. The stop element profile 28 includes a plurality of stop element profile segments 29a, 29b, ... The stop element profile segments 29 have different radii relative to the rotation axis 27. For the illustrated embodiment, the stop element profile 28 additionally has a wave-shaped curvature, so that the stop element profile segments 29 are all arranged in the troughs, so that adjacent stop element profile segments 29 are separated from each other by the ridges of the waves.

[0073] Here, the stop element 25 is implemented as a journal of the second end of the brake actuating shaft 16. For the embodiment shown, the cam disc 26 is arranged on the rear side of the machine housing 2, and the journal 30 extends through the strip hole 31 of the machine housing 2 to the rear side of the machine housing 2. The strip hole 31 is arc-shaped, and the center of the semicircular longitudinal axis of the arc is located on the pivot axis 4. The shaft diameter 30 is supported by one of the selected stop element profile segments 29. Changing the selected stop element profile segment 29 in which the journal 30 is located will result in a change in the starting pivot angle 39. In this position, the selected stop element profile segment 29 can act within a suitable (stop) angle relative to the transverse mechanism carrier 3, corresponding to the diameter of the winding sleeve 11 used.

[0074] Figures 5 to 10 Different operating states of the winding machine 1 are shown. Fig.11 Refer to the principle block diagram Figures 5 to 10 The diagram and operating states illustrate the operating method of the winding machine 1:

[0075] In method step 32, the transverse mechanism carrier 3 is pivoted about the pivot axis 4 to an alternative pivot angle 33, at which the pressure roller 7 is at a maximum distance from the spindle 9. The brake device 13 is in the applied state. In this operating state of the winding machine 1, the finished bobbin can be removed from the spindle.

[0076] In method step 34 , a new winding sleeve 11 is positioned on the spindle 9 and fixed to the spindle 9 by suitable fixing means in order to transfer future rotational movements of the spindle 9 to the winding sleeve 11 .

[0077] In method step 35, the transverse mechanism carrier stop 23 is adjusted according to the specific type of winding sleeve 11 used. Figure 5 In the example shown, the outer diameter of the particular winding sleeve 11 is 47 mm. In order to make the required adjustment, the cam disc 26 needs to be rotated so that the operator can see the indicator 46 (here the indicator "47") through the strip hole 31. In this position of the cam disc 26, the stop element contour segment 29j is arranged in the center of the strip hole 31. The rotation of the cam disc 26 can be achieved by the operator by turning the manual operating wheel 37 on the front side of the machine housing 2.

[0078] In the next method step 38, the brake device 13 is released and the operator pivots the transverse mechanism carrier 3 from the replacement pivot angle 33 to the starting pivot angle 39, such as Figure 6 When the initial pivot angle 39 is reached, the journal 30 contacts the stop element contour segment 29j, thereby generating a stop so that the pivot angle 12 cannot be further reduced. At the initial pivot angle 39, a gap 40 is formed between the outer surface of the winding sleeve 11 and the pressure roller 7.

[0079] In the next method step 41, the winding material is transferred to the main shaft 9 or the winding sleeve 11 and fixed thereto. The brake can be released and the main shaft 9 and the winding sleeve 11 can be rotated together by starting the motor (see Figure 7 ). The first winding process stage begins. In the first winding process stage, the winding product is wound on the winding sleeve 11, thereby forming a first winding. The gap 40 gradually decreases. At the end of the first winding process stage, the outer surface of the winding contacts the pressure roller 7 (see Figure 8 ).

[0080] Due to this contact, the contact force between the journal 30 and the stop element profile segment 29j is reduced, so that the first winding process phase ends and the second winding process phase begins. In the second winding process phase, the outer diameter of the winding material increases further, so that the contact force exerted on the pressure roller 7 biases the transverse mechanism carrier 3 so that the pivot angle 12 increases. Fig. 9 and Fig.10 As shown, the pivot angle 12 is further increased until the second winding process phase is completed (see Fig.10 ), the bobbin winding is completed.

[0081] Figures 12 to 15 The design of the transverse mechanism carrier stop 23 and the design of the latch 42 that secures the transverse mechanism carrier stop 23 in a selected position are shown in more detail. Fig.13 , Fig.15 These are explained in detail in XIII and XV of the .

[0082] The stop element 24 comprises a manually operated wheel 37, which can be pushed axially by an operator and rotated about the axis of rotation 27. The manually operated wheel 37 is fixedly connected to the cam disc via a shaft 43 (extending through the machine housing 2). On the side facing the rear side of the machine housing 2, the cam disc 26 comprises a protrusion 44. The machine housing 2 has corresponding recesses 45a, 45b... The recesses 45a, 45b... are arranged in the circumferential direction about the axis of rotation 27 at positions corresponding to the ideal rotation position of the stop element 24, in which position the selected stop element profile segment 29 interacts with the journal 30. Fig.13 In the embodiment of the present invention, the user pushes the stop element 24 against the bias of the spring 46, so that the protrusion 44 moves out of the recess 45. In this way, the operator can rotate the stop element 24 to select different operating states. When the axial force is released from the manual operating wheel 37, the protrusion 24 enters one of the recesses 45 due to the force applied by the spring 46 (see Fig.15 ).

[0083] If the contact surface of the protrusion 44 and the recess 45 is perpendicular to the circumferential direction of the rotation axis 27, the manual operating wheel 37 must be pushed axially of the rotation axis 27 to allow the stop element 24 to rotate. In this case, according to the above definition, the latch device 42 is a locking device.

[0084] Conversely, when the contact surface is tilted, any rotational torque applied by the user to the manual operating wheel 37 will generate a downward force, biasing the spring 46 in the compression direction. Therefore, by determining the tilt angle, the radius of the protrusion 44 relative to the rotation axis 27, and the stiffness of the spring 46, the rotational torque that the operator must apply to change the rotation angle of the stop element 24 and release the protrusion 44 from the recess 45j can be designed. In this case, according to the above definition, the latch device 42 belongs to a snap-in connection device.

[0085] The switch mechanism 47 actuated by the brake device 13 can trigger the driving operation of the motor to rotate the main shaft 9 together with the winding sleeve 11. According to the embodiment shown, the switch mechanism 47 includes a sensor 48. The sensor 48 includes sensor elements 49 and 50. The sensor element 49 is attached to the manual actuation lever 15, while the sensor element 50 is attached to the transverse mechanism carrier 3 (see Figure 3 , 5 , 8, 9 and 10). The sensor may be implemented as a Hall sensor 51 or the like. In this case, one of the sensor elements 49, 50 is a permanent magnet, and the other of the sensor elements 50, 49 is a circuit that senses the magnetic field of the permanent magnet.

[0086] As from Figure 6 to Figure 7 It can be seen from the change that when the starting pivot angle 39 of the lateral mechanism carrier 3 is triggered, the manual actuating lever 15 can be moved from the applied state ( Figure 6 ) is pivoted to the release state with the brake device 13 (see Figure 7 ) corresponding to the position. In this way, the distance between the sensor elements 49, 50 is shortened. If the control unit controlling the motor detects that the distance between the sensor elements 49, 50 is less than the threshold value, this detection result can be used to trigger the motor to start, thereby starting the first winding process stage.

[0087] The braking device 13 is preferably always applied for creating a braking torque (also during the winding process), except during the time when the transverse mechanism carrier 3 is manipulated to change its pivot angle about the pivot axis 4 .

[0088] The applicant's European patent EP2436632B1 discloses a winding material suction gun, which can be used to collect and transfer continuous winding materials, in particular continuously wound yarns or thread-like objects, that is, from a first (completely wound) spindle, winding sleeve and / or bobbin on a winding station of a winding machine to a second (empty) spindle and / or winding sleeve on a second winding station of the winding machine. During the winding process, the winding material suction gun is parked (in particular placed or stored) in a holding device arranged close to the winding machine. The disclosure of patent EP2436632B1 particularly relates to:

[0089] - Suction gun for winding material,

[0090] - holding device,

[0091] - conveying the winding material using a winding material suction gun, and

[0092] - Different method steps for continuing the winding process after transfer.

[0093] This patent application refers to these contents.

[0094] In one embodiment of the invention, the actuation of the motor driving the spindle is not only dependent on the actuation of the brake device. To actuate the motor, a winding material suction gun and a holding device, such as the device described in EP2436632B1, can be used, in particular when the machine / device is in operation and running and the completed (wound) bobbin is to be replaced by a winding sleeve of the yarn to be wound. As soon as the corresponding gun is removed from the holding device, the motor for the spindle can be actuated. The holding device and / or the winding material suction gun may include a sensor for sensing the presence or removal of the winding material suction gun in the holding device. The signal of the sensor is transmitted to the control device of the (driving spindle) motor. In this case, the motor is actuated by the switching mechanism only when the brake device is actuated and when the above-mentioned sensor sends a signal that the winding material suction gun is removed or has been removed from the holding device.

[0095] In another embodiment in which no winding material suction gun and associated holding device are used, the winding machine may (alternatively or additionally) comprise an additional manual switch, for example on the front side of the machine frame or even on the transverse mechanism support, for actuating the motor to drive the spindle and / or deactivating the motor, so that by manually actuating the additional manual switch by the user, the actuation of the braking device to switch the motor on and off can be bypassed.

[0096] However, in general, whether it is to start the winding process of the machine / equipment, and / or replace the winding sleeve to produce a new bobbin, and / or correct an erroneous winding or a winding process failure (for example, due to yarn breakage or undesired winding) during the winding process, the brake device (preferably a manual actuation device) and / or the switch mechanism are used to actuate the motor for the main shaft. It goes without saying that in the opposite case, the operation of the brake device connected to the switch mechanism is also the same, that is, the brake device, when operated (by an operator), slows down / stops the motor driving the main shaft by actuating the switch mechanism, which can be completed at any process stage of the winding machine and / or equipment, that is, to achieve the purpose just mentioned.
