Definitions

  • the invention relates to a device for winding a web onto a winding core, with two winding rollers, between which the web to be wound is fed through to the winding core.
  • the invention is based on the object of creating a device with which the start of a web of material can be wound up onto a winding core automatically, that is to say without any manual work. Feeding the web, introducing the web between the winding rollers, core formation and further winding should therefore take place completely automatically without manual labor, with the core forming and winding in one direction or the other, for example with the visible side facing inwards or outwards, being possible.
  • the material web is thus automatically fed into the winding rollers in the manner of a rising dock from bottom to top and introduced into the winding area.
  • the winding area forms a closed space above the winding rollers, which, together with the winding auxiliary device, completely surround the winding core, so that a winding start is formed in a simple and completely automatic manner and further winding is possible.
  • one or the other side of the web can optionally be wound inwards or outwards on the winding core.
  • the winding core can not be fed by hand but automatically and inserted into the area above the winding rollers, which means that not only the winding process itself, but also its new beginning can be fully automated with each new winding core.
  • the device according to the invention essentially has a memory for winding cores and a swivel arm for transferring the winding cores from the memory to the winding area.
  • a swivel arm for transferring the winding cores from the memory to the winding area.
  • a material web W to be wound is fed to the winding device via a conveyor.
  • the conveyor consists of three deflecting rollers 1a, over which a conveyor belt 1 runs.
  • the supply of the web W is more or less horizontal, while the continuation of the web W to the actual winding device is essentially vertical from bottom to top.
  • the deflector immediately upstream of the winding device is lifted roller la arranged a stationary support roller 2.
  • the web W is passed between these two latter rollers.
  • the conveyor belt 1 is synchronous, ie with. driven at the same speed as the entire rewinder.
  • the deflection roller 1a located on the inlet side is movably mounted and spring-loaded via a pendulum rocker. It is supported against a spring 3.
  • two winding rollers 5 and 6 are arranged side by side, between which there is a distance or gap A through which the web W runs upwards.
  • the winding rollers 5 and 6 are driven in the same direction of rotation, so that there is an opposite movement of the surfaces of the two winding rollers 5 and 6 on both sides of the gap A.
  • the direction of rotation of both winding rollers 5 and 6 is reversible in order to enable winding of the material web W onto a winding core 16 above the winding rollers 5 and 6 in both directions of rotation. It is thereby achieved that on the winding core 16 either the side lying at the top of the web W or the bottom, with a floor covering or carpet z.
  • B. the pile side or the bottom can be wound inwards or outwards.
  • a special insertion control enables the counter-rotation of the winding rollers 5, 6 with the conveying direction upwards, so that goods can also be transported upwards with a strong swirl.
  • the left winding roller 5 is mounted in a fixed position, while the right winding roller 6 is mounted with its axis between the positions 6a and 6b to be horizontally displaceable.
  • the left winding roller 5 can also be mounted displaceably in the lateral direction.
  • This displaceability of one or both winding rollers 5, 6 serves to have a narrow gap or distance A between the two winding rollers when inserting the beginning of the web W, so that the ascending web of goods does not tip over but is stabilized in its upward direction of movement. If, on the other hand, after some time of winding the material web W onto the winding core 16, the diameter of the winding becomes larger, it is advantageous to increase the distance A between the winding rollers 5 and 6, i.e.
  • guide plates 4 are provided in this area, between which the web W is led upwards into the gap A.
  • 4 air nozzles 41 and 42 are provided in the area of the guide plates, which blow an air flow into the gap A from bottom to top. These air nozzles are preferably provided in the guide plates 4.
  • the air nozzles 41 and 4'2 can be controlled alternately or alternately, so that the air stream emerging from at least one of the nozzles causes the beginning of the web W to be applied to one of the two winding rollers 5 or 6, in the exemplary embodiment shown to the right winding roller 6 Depending on the desired winding direction of the web W on the winding core 16, an air cushion is thus built up below this winding core 16 on one side of the web, which determines the winding direction.
  • the illustrated embodiment offers a particularly simple and expedient construction, in which air nozzles 41 and 42 are provided only below the gap A at the upper ends of the guide plates 4.
  • a friction-increasing coating can be applied in a known manner, which improves the entrainment of the web W.
  • the support of the winding process by the air flow is only effective when the winding roller 6 is in the position 6a, that is, with a narrow gap A. This is only so wide that the web W is guided by the winding rollers running in opposite directions in the area of the gap A. 5 and 6 is not affected. In this case, the air support presses the web W onto the roll circumference of the winding roller 6 that runs upward. As a result, the area Z in the gusset above the gap A, which cannot be further controlled, becomes the smallest, so that the web W cannot become entangled in an uncontrolled manner.
  • a winding auxiliary device for winding is arranged above the winding rollers 5 and 6.
  • This consists of three auxiliary rollers 7 which are connected to one another by means of a plurality of conveyor belts 8 distributed over their width.
  • the axes of the three auxiliary rollers 7 form a triangle, preferably an isosceles triangle.
  • the active parts of the winding members (auxiliary rollers 7 and conveyor belts 8) are thus roof-shaped over the winding rollers 5 and 6.
  • the winding auxiliary device with the winding rollers 7 and the conveyor belts 8 can be moved up and down in the direction of arrow 13 with respect to the winding rollers 5 and 6 .
  • the winding auxiliary device 7, 8 is slidably mounted in a frame, not shown, with a corresponding lateral guide.
  • this device (auxiliary rollers 7, belts 8) is supported against a spring 12 which constantly exerts pressure on the device downwards.
  • the winding auxiliary device Before the winding process begins, the winding auxiliary device is in the upper starting position. Before the beginning of the web W between the winding rollers 5 and 6 rises up through the gap A, a winding core 16 is inserted in the position 15a or 15b over these winding rollers 5, 6.
  • the winding core 16 comes, for example, from a memory 21, 21a (FIG. 2).
  • the winding core 16 is in the position 15a or 15b left or right above the trough or the gusset Z between the winding rollers 5 and 6, so that the beginning of the web can be guided upwards in the desired manner.
  • the top of the incoming web W is to be wound on the winding core 16 inwards.
  • the winding core is therefore initially in the position 15a on the left above the winding roller 5.
  • the air nozzles 41 and 42 are controlled so that the beginning of the web W lies to the right against the winding roller 6 and from there to a height of approximately 70 ° the horizontal is taken up.
  • the device is stopped in this position.
  • the winding core 16 is transferred from the position 15a to the central position above the gusset Z, as will be described below.
  • the surface of the winding core 16 thus comes into contact with the top or outside of the beginning of the web W to be wound inwards.
  • the winding auxiliary device with the auxiliary rollers 7 and the conveyor belts 8 is lowered onto the winding core 16. After the drive has been switched on, the start of the web W, carried along by the conveyor belts 8, automatically runs around the winding core 16, so that the winding process is initiated.
  • the three auxiliary rollers 7 with the conveyor belts 8 have the same peripheral speed as the winding rollers 5 and 6. Also the three deflecting rollers 1a, the conveyor belt 1 and the support roller 2 of the feed conveyor have the same peripheral speed, so that a synchronous winding of the web W is possible without slippage . The web W is thus frictionally wound on the winding core 16.
  • the diameter of the wound roll gradually increases, so that the winding auxiliary device with the auxiliary rollers 7 and the conveyor belts 8 is pressed upwards against the spring 12.
  • the arrangement can be such that a contact is actuated after only a few revolutions of the winding core 16, when the beginning of the winding has sufficiently tightened on the winding core 16, which causes the winding auxiliary device 7, 8 to automatically return upwards to the starting position .
  • the further winding up to the desired thickness of the goods roll or up to the desired length of the web wound, the removal of the finished winding then takes place with the winding auxiliary device 7, 8 raised, so that this does not hinder the actual winding process and the removal of the winding.
  • a contact can also be actuated which moves the winding roller 6 from the position 6a to the position 6b, so that the distance between the winding rollers 5 and 6 increases and the material web W can be wound without a sharp deflection onto the winding, which increases in diameter.
  • a storage container for winding cores 16 is located above the winding device, of which essentially only the two winding rollers 5 and 6 are shown.
  • the storage container consists of two separate stores 21 and 21a, which are arranged next to one another.
  • a plurality of separate stores can be provided for winding cores 16 with different lengths and / or different diameters.
  • Each store 21, 21a has a lower outlet opening 27, 27a. Through this individual winding cores 16 can emerge downwards.
  • a retaining member 22, 22a for the winding cores 16 is provided at the outlet openings 27, 27a.
  • the retaining member 22, 22a can, for. B. have the shape of a cross slide closing the outlet openings 27, 27a.
  • the retention members 22, 22a can be controlled separately from each other to release the associated outlet opening 27, 27a.
  • a pivot arm 23 which can be pivoted about a horizontal pivot axis 24, which extends laterally above the winding rollers 5 and 6 parallel to the winding rollers 5 and 6, is arranged underneath the stores 21, 21a as an essential part of the device.
  • the winding arm 23 carries a funnel-shaped receptacle 30 for an individual winding core 16.
  • the pivot arm 23 can be pivoted about the pivot axis 24 into a vertical position in such a way that its receptacle 30 passes under one of the outlet openings 27, 27a.
  • a winding core 16 falls out of the respective memory 21, 21a into the receptacle 30.
  • the retaining element 22, 22a locks the outlet opening 27, 27a again immediately.
  • the swivel arm 23 or its receptacle 30 has a lateral passage opening 31 for the winding cores 16.
  • This passage opening 31 is controlled by a control element 26, for example a slide. In the position shown, the control member 26 locks the passage opening 31 so that the winding core 16 cannot fall out.
  • the pivot arm 23 with its pivot axis 24, z. B. along a rail, not shown, in a direction transverse to the axis of the winding rollers 5 and 6 laterally displaceable.
  • the pivot axis 24 can be locked in three displacement positions a, b and c.
  • the position b corresponds to the position in which a winding core 16 is released to the winding rollers 5 and 6 by the horizontally positioned swivel arm 23.
  • a winding core 16 is received from the right-hand memory 21a in the position. B and a winding core 16 from the left-hand memory 21 in the position a.
  • the vertical swivel arm 23 could have a winding core from a third , record undrawn memory.
  • Fig. 2 shows that the pivot arm 23 carries on its right and lower side two rows of scraping members 28 and 28a, which are designed here as brushes. These brushes protrude from the horizontal position of the swivel arm 23 this down against the winding rollers 5 and 6.
  • the scraping elements or brushes extend perpendicular to the plane of the drawing over a length which corresponds to the greatest width of the material web to be wound up with the aid of the winding rollers 5 and 6.
  • the scraping elements or brushes 28, 28a are arranged in a row on both sides of the passage opening 31.
  • the scraping elements or brushes 28, 28a serve to press the beginning of the web running upwards between the winding rollers 5 and 6 in the desired direction and position at the beginning of the winding process and to hold it until it is carried along by the winding device.
  • the material web is to be wound around the winding core 16 counterclockwise, the beginning of the material web runs in on the path 11 between the winding rollers 5 and 6.
  • the swivel arm 23, which had previously received a winding core 16, is shifted into position a.
  • the receptacle 30 with the winding core 16 is now located above the left winding roller 5.
  • the right scraping element 28a thus comes to rest on the winding roller 5. If the swivel arm 23 is now moved from the position a to the position b, the free upper end of the web is gripped by the right scraping element 28a and pressed against the right winding roller 6.
  • the winding core 16 is released via the control member 26 and falls down into the gusset between the winding rollers 5 and 6, whereby it bears directly on the winding roller 5 and on the winding roller 6 via the intermediate beginning of the web.
  • the swivel arm 23 is now pivoted into the vertical position, and the winding auxiliary device 7, 8 is lowered in order to wind the beginning of the web onto the winding core 16.
  • the winding device described can be used wherever webs have to be wound or rewound, for. B. in carpets, weaving mills and similar companies.
  • the use of the device for unwinding certain lengths of a material web from a supply and for winding up these measured lengths (coupons) on a winding core is particularly advantageous.
  • the device can also be used to advantage in trade.
