Definitions

  • the invention relates to a device for transporting a winding shaft in a fleece winder from a waiting position to a start-up position and from this to a winding position of the fleece winder, as well as a fleece winder equipped therewith.
  • Fleece winder per se are known. They serve to wind a fleece coming out of a card, for example, onto a winding shaft. For this purpose, empty winding shafts are placed in a magazine of the fleece winder and gradually brought into a waiting position.
  • the waiting position serves, on the one hand, to separate the winding shaft from the other winding shafts and, on the other hand, to set it in rotation before the actual winding process begins.
  • it is provided to convey the winding shaft from the waiting position to a winding position in which the winding shaft to be wound comes into frictional contact with a contact roller on which the fleece runs in the area of the fleece.
  • JP H03 177253 A discloses a winder in which an empty winding shaft is moved along a horizontally extending running surface in the winding-on position between two rollers.
  • the object of the invention is therefore to improve the safety of a fleece winder when conveying the winding shaft from the waiting position to the starting position.
  • a fleece winder which has a holding section, a transport section and a guide section.
  • the holding section is designed to receive a winding shaft.
  • the guide section has a running surface which essentially points away from a floor on which the fleece winder is set up and is designed to take up the weight of the winding shaft.
  • the transport section and guide section are also designed to move the winding shaft from the holding section on the running surface in the direction of a winding-on position in which the web winder is set up to wind the winding shaft with a web located on a contact roller of the web winder.
  • the weight of the winding shaft rests on the guide section during the entire process. This has the advantage that the elements gripping the winding shaft have to apply significantly less gripping force. In addition, the winding shaft cannot fall off in the event of a malfunction, which improves safety in particular for an operator.
  • the winding shaft is guided near the running surface, where near means a range of a few millimeters or even below a millimeter.
  • the transport section has to take up the weight of the winding shaft, but a malfunction does not lead to the winding shaft that may come loose in an uncontrolled manner or cause damage to the fleece winder.
  • the low height of fall means that there is hardly any risk of damage to the running surface.
  • the winding shaft cannot leave the gap between the transport section and the running surface, so that it can continue to be exclusively in the area of the transport section.
  • the distance between the running surface and the holding section preferably first increases in the direction of the winding position and then decreases again.
  • the travel path of the winding shaft, along which the winding shaft can roll away in the event of a malfunction and possible loosening of the gripping device that is intended to grip the winding shaft, is thus virtually halved. This reduces the final speed of the winding shaft and thus also improves operational safety.
  • the running surface preferably runs continuously. This means that there are hardly any vibrations on the web winder while the winding shaft is being transported.
  • the running surface seen transversely to the direction of movement of the winding shaft, is preferably designed as a circular arc or elliptical. These are particularly well-suited tread shapes, in particular to keep the acceleration and final speed of a winding shaft loosening within limits.
  • the guide section can be part of a frame wall of the web winder. This therefore takes on a double function and, in addition to maintaining the number of parts, enables constant external dimensions of the web winder, at least in terms of width and length.
  • the fleece winder can have a sensor system. This is set up to detect when the winding shaft is in the holding section or in the starting position. This enables the web winder to be controlled, for example to initiate the application and / or separation of the web when the winding shaft is in the winding-on position.
  • the sensor system can be of an optical, magnetic and / or mechanical nature. It can therefore be optimized to the respective requirements.
  • each of the aforementioned fleece winders can have a locking section. This is designed to attack the winding shaft from a side facing away from the contact roller. It is also attached to a movement section which is set up to move the locking section in the direction of the contact roller. Accordingly, it can be sufficient to only move the movement section in order to move the winding shaft from the waiting position into the winding-on position. This leads to a very simple and inexpensive structure.
  • the movement section preferably has a linear guide by means of which the locking section is guided along its movement.
  • the linear guide enables the use of a pneumatic drive.
  • the movement section preferably comprises a pivotably mounted lever. This is arranged rotatably around an axis of the contact roller.
  • the fleece winder is set up to coordinate the movements of the lever and the locking section in such a way that the winding shaft is safely carried along by the locking section during its movement to the winding position. In particular with an initially rising running surface, this makes it possible not to let the pressure of the winding shaft on the running surface become too great, which is beneficial to operational safety.
  • Each of the aforementioned locking sections can be designed to grip the winding shaft in such a way that it cannot fall out. This increases the security that the winding shaft cannot easily loosen even in the event of a malfunction.
  • the guide section can be at least partially relieved of its weight by slightly lifting the winding shaft, for example within a few millimeters while the winding shaft is being conveyed.
  • the holding section, transport section and guide section can each be provided in duplicate, specifically on opposite sides of the fleece winder. This enables the winding shaft to be conveyed by means of its ends.
  • the area for receiving the fleece is therefore not subject to any mechanical stress from the conveyance and can be optimized for the winding up of the fleece.
  • a method for operating one of the aforementioned fleece winder first has a step of engaging the winding shaft located in the holding section at least from a side facing away from the contact roller of the fleece winder by means of a locking section of the fleece winder. Subsequently, within the scope of the method, the locking section is moved in the direction of the contact roller by means of the moving section of the fleece winder. Furthermore, there is a step of detecting the presence of a state in which the winding shaft has reached the winding-on position. If this state is detected, the movement section is stopped.
  • the invention offers a very simple method for conveying a winding shaft from the waiting position to the winding-on position.
  • Figure 1 shows a fleece winder 1 according to an embodiment of the invention.
  • the constituents that are not essential to the invention are not explained further.
  • the fleece winder 1 essentially comprises two frame walls 20, which are combined to form a frame via connectors (not designated), which receives or holds all other functional elements of the fleece winder 1.
  • the frame walls 20 have a magazine 2 in which there are unmarked winding shafts (here: two).
  • the fleece winder 1 comprises a recess on each frame wall 20 which defines a waiting position 3 for a winding shaft 7. Since the winding shafts are held on both sides by a respective frame wall 20, a waiting position 3 is thus implemented by means of the two frame walls 20.
  • the frame walls 20 thus form a holding section for a winding shaft 7 by means of the waiting position.
  • the winding shaft 7 arranged therein is set in rotation by means of a turning section 11.
  • the turning section 11 makes contact with the area of the winding shaft which is used to receive fleece.
  • the entire winding shaft 7 is set in rotation but only its winding section, which is arranged in the center here and which forms the actual winding surface on the circumferential side.
  • a first transport section 9 is provided.
  • the fleece winder 1 has a start-up position 4 which is located in a kink area, seen along the axis of rotation of the contact roller 8 of the fleece winder 1, between the frame wall 20 and a contact roller 8.
  • the contact roller 8 leads the incoming fleece to the winding shaft to be wound in a known manner.
  • a separating section 12 which comprises a cutting section not further designated here.
  • the fleece winder 1 has a winding position 5, which is implemented by means of a section between the frame wall 20 and the contact roller 8 arranged here on the left. In this position 5, the corresponding winding shaft, which has already picked up fleece in the winding-on position 4, is finally wound.
  • a locking and movement section 100 is used, which thus forms a second transport section.
  • the fleece is separated by means of the separating section 12, and the wound winding shaft is moved into an ejection position 6 of the fleece winder 1 by means of a winding and push-out section 10.
  • Each frame wall 20 has an upwardly pointing running or guide surface 21, which extends mainly from the waiting position 3 to the winding position 4.
  • Figure 2 shows the fleece winder 1 with regard to its locking and movement section 100.
  • the locking and movement section 100 preferably comprises elements on both outer sides of the frame walls 20 which serve to move the winding shaft 7 from the starting position 3 to the starting position 4.
  • These elements each include a belt 113 that is looped around an associated pair of pulleys 116, 119. By rotating An associated swivel part 120 is rotated with the respective belt pulley 116, which is not visible here.
  • a connecting shaft 114 is provided to movably connect both pulleys 119, of which only the front one is visible.
  • the connecting shaft 114 is received in a freely rotatable manner in the frame walls 20 by means of pivot bearings 22, passing through both frame walls 20.
  • a drive section 30 is provided, by means of a motor 31 and here a gear 32 via a belt 33, to drive a belt pulley 34 which is preferably arranged coaxially to the respective belt pulley 116 and which is arranged non-rotatably relative to the contact roller 8, but freely rotatable with respect to the belt pulley 116.
  • FIG. 3 shows the web winder 1 with regard to its locking and movement section 100 from FIG Figure 1 The rear side and without the drive section 30. As a result, the adjacent belt pulley 116 located behind it in the direction of the contact roller 8 becomes visible. As can be seen, the arrangement is essentially the same as on the front side of the fleece winder 1 in FIG Figure 2 .
  • a drive section 110 which, in the example shown, has a motor 111 with a gear 112. Via the transmission 112, the motor 111 is able to set the associated lower deflecting pulley 119 in rotation, around which the belt 113 is looped. Via the connection to the connecting shaft 114, the motor 111 is thus able to drive the in Figure 2 locking and moving section 100 shown to also set in motion.
  • the drive section 110 is preferably fastened to the frame wall 20 shown here by means of a fastening element 101.
  • the locking and movement section 100 comprises two pivoting parts 120, which are arranged in a rotationally fixed manner with respect to a respective belt pulley 116.
  • Belt pulley 116 and pivot part 120 can just as easily be formed in one piece with one another.
  • Figure 4 is again a representation of Figure 2 in greater detail and without the contact roller drive section 30. It can be seen here that a tensioning roller 117 is preferably provided in order to put the belt 113 under the necessary pretension.
  • Figure 5 includes two enlarged views of Figure 4 .
  • the belt pulley 116 and the pivoting part 120 are fastened to one another by means of fastening elements 118 such as screws.
  • a pneumatic cylinder 121 together with a linear guide 123 is attached to the pivoting part 120.
  • the linear guide 123 translates a slide 122 from right to left and back.
  • a locking section 130 is in turn fastened to the slide 122.
  • the locking section 130 comprises a pneumatic cylinder 131, which is attached to the slide 122 in a pivot-articulated manner with one end facing away from its piston 132.
  • the free end of the piston 132 of the pneumatic cylinder 131 is in turn fastened in a pivot-joint manner to a locking lever 133, which in turn is also pivot-jointly fastened on the slide 122.
  • the pneumatic cylinder 131 By moving out the piston 132, the pneumatic cylinder 131 is able to move the pivot lever 133 in the direction of the winding shaft 7, so that it is held by means of the locking section 130.
  • the pneumatic cylinder 121 is able to move the slide 122 along the linear guide 123 via its piston (not shown here).
  • the belt 113 is moved by means of the drive section 110, which is not visible here, in such a way that the belt pulley 116 is rotated here counterclockwise.
  • the arrangement of pivoting part 120, pneumatic cylinder 121, linear guide 123 and locking section 130 is now rotated with it.
  • the locking section 130 initially rotates about the axis of rotation of the contact roller 8.
  • the carriage 122 In order to keep or guide the winding shaft 7 in contact with or very close to the running surface 21 of the frame wall 20, when pivoting by means of the pneumatic cylinder 121 or by retracting its piston, the carriage 122 is gradually moved in the direction of the axis of rotation of the pivoting part 120 along the Guide 123 moves. Near means preferably in the millimeter range or below.
  • Figure 6 shows one to Figure 5 Similar view of the fleece winder 1 when the winding shaft 7 is in the start-up position 4.
  • the fleece is transferred from the contact roller 8 to the winding shaft 7 by means of a known frictional connection between the winding shaft 7 and the contact roller 8, and the winding shaft 7 is thus wound on.
  • the pivoting part 120 is according to FIG Figure 6 turned further counterclockwise towards winding position 5. In the context of the linear guide 123, care is now taken to ensure that the winding shaft 7 is constantly in contact with the contact roller 8.
  • the locking section 130 releases the winding shaft 7 again and the pivoting part 120 is rotated back in the opposite direction, i.e. clockwise according to FIG. 6, to take over the next winding shaft in waiting position 3 when the winding shaft 7, which is now in the winding position 5, is almost fully wound and the fleece is to be transferred to a new winding shaft 7.
  • the running or guide surface 21 advantageously runs continuously and is preferably formed in the shape of a circumferential line of a circle or an ellipse. In any case, it reduces its distance from the floor on which the fleece winder is set up, at least in the direction of waiting position 3 or starting position 4.
