Description

The invention relates to a winding shaft for use in nonwoven winder and a nonwoven winder provided therefor.

Nonwoven winder are known per se. They serve to wind a fleece, for example coming out of a carding machine, onto a winding shaft. For this purpose, empty winding shafts are automatically wound in succession. This is done by passing incoming nonwoven material around a rotating contact roll. An empty winding shaft, which is provided with an adhesive surface and rotates in the direction opposite to the contact roller, is applied to the contact roller and takes over the nonwoven from the contact roller due to the adhesion action. If the winding shaft is full, a new, empty winding shaft is brought from a magazine to a waiting position, turned on and then applied to the contact roller. At this moment, the still wound on the previous winding shaft fleece in the contact roll is separated. Thus, the web can be removed with the free end of the empty winding shaft due to the adhesion of the contact roller. In this case, the just wound winding shaft is moved to a Ausschubposition. The just-wound winding shaft is moved around the contact roller around in a winding position in which the winding shaft is wound to the end. Ie. Each winding shaft is in succession in one of usually five positions: in the magazine, in the waiting or cranking position, in the winding position, in the winding position and in the ejection position. It is, apart from rotating, subjected to three movements: from the magazine to the waiting position, from the waiting position in Anwickelposition, of the Winding position in winding position and from the winding position in Ausschubposition. The winding shaft is brought by an element in the respective position and handed over until reaching the winding position of a driver element to another quasi. These elements overlap in pairs in the respective common position of the winding shaft, seen in the direction of the axis of rotation. There is a risk that the winding shaft can move in one of the positions and / or when moving between the individual positions along its axis of rotation.

The object of the invention is to remedy this disadvantage as far as possible.

This object is solved by the subject matter of claims 1 and 11. Advantageous developments are specified in the subclaims.

According to the invention, a winding shaft is provided, which is designed to be used in a nonwoven winder for winding a nonwoven. It has a winding section which is designed to receive the nonwoven on an outer peripheral surface when the winding shaft rotates. The outer peripheral surface extends substantially parallel to a rotation axis of the winding shaft. The winding shaft also has a storage section, in or on which the winding section is mounted freely rotatable. The storage section has, seen transversely to the axis of rotation, recesses. These are designed to be received in a magazine and / or a waiting section of the nonwoven winder so that the winding shaft is prevented from moving along its axis of rotation. Ie. The winding shaft itself ensures that it can not move in the direction of the axis of rotation.

Preferably, at least one of the recesses is formed circumferentially. As a result, it is irrelevant in which rotational position about the axis of rotation the winding shaft is arranged in the nonwoven winder.

In both variants, the storage section may further comprise at least one additional recess. This is designed to prevent the winding shaft from moving along its axis of rotation in the winding shaft lock when clamped by means of a winding shaft lock of the nonwoven winder. It is therefore a recess designed for a very specific purpose.

In all of these winding shafts, at least one of the recesses may be formed like a groove. This allows a simple design example of the magazine. In case of doubt, one edge is sufficient to receive the winding shaft at the respective recess in stock.

In each of the aforementioned winding shafts, the storage section may comprise at least one sleeve which receives the winding section at one end freely rotatable. This makes it possible to form the winding shaft as a standard type part and to adapt to the recording only by means of the sleeve to the respective nonwoven winder. A second advantage is that the storage portion performs several functions: preventing movement of the winding shaft along the axis of rotation with respect to the nonwoven winder and freely rotatably receiving the winding portion provided for receiving the nonwoven fabric. The sleeve also makes it possible to limit the wear just on the sleeve due to the storage and movement prevention function. Ie. the rest of the winding shaft is almost wear-free, which helps keep costs low during operation.

Preferably, the storage portion comprises two sleeves which receive the winding portion freely rotatable at both ends. This makes it possible to provide the winding shaft only at their ends with the additional functions, so that a maximum winding width can be realized.

The at least one sleeve can be designed to be open on both sides in the two last-mentioned variants, viewed in the direction of the axis of rotation. This makes it possible to postpone the sleeve to the other winding shaft and replace it if necessary, if it is worn.

In each of the above-mentioned winding shafts, the winding section preferably has a circular cylinder section, seen in cross section, along the axis of rotation, which includes the outer peripheral surface for receiving the nonwoven. This is a particularly suitable form for receiving the fleece.

In each of the aforementioned winding shafts, a wall of one of the at least one recess, viewed transversely to the axis of rotation, may face or face away from the outer peripheral surface for receiving the fleece. In addition, it is formed in the direction of the axis of rotation at least in sections on the winding section to or extending away from it. This allows a simple way the formation of the respective recess.

Each of the aforementioned winding shafts is preferably formed, viewed transversely to the axis of rotation, symmetrical. This makes it possible, especially in the design with two sleeves, the use of identical parts, which helps keep the manufacturing costs low. Another advantage is that the winding shaft can also be rotated 180 °, So there is no faulty operation of the winding shaft or at least reduced.

According to the invention, a nonwoven winder is further provided. This is set up to wind a winding shaft with an incoming fleece. It also has a receiving portion and at least one of the aforementioned winding shafts, which is received in stock in or on the receiving portion with the storage section. The receiving portion includes a magazine configured to receive a plurality of winding shafts and / or a waiting section configured to receive a winding shaft. The waiting section serves to separate a winding shaft from the magazine and to set for winding in rotation.

Preferably, the receiving portion further comprises a winding portion, also designed to receive a winding shaft. The winding section is the area of the nonwoven winder in which the respective winding shaft is wound with the nonwoven.

In the case of both nonwoven winder, the receiving section can have, on two opposite sides of the nonwoven winder, two support edges facing away from a bottom on which the nonwoven winder is mounted, on which the respective winding shaft rests with its storage section. This is a particularly simple and inexpensive to manufacture structure. It can be realized for example by means of an upper edge of a frame wall of the nonwoven winder.

Each of the two support edges is preferably configured to receive the support portion so that the received winding shaft starts to move is prevented along its direction of rotation. Ie. in interaction with the storage section, the winding shaft, in the direction of the axis of rotation or longitudinal extension, held in position.

The obstacle to this movement is preferably carried out by at least one of the two support edges is designed to be positively engaged with an associated support portion of the storage portion of the respective winding shaft. Alternatively or additionally, both support edges may comprise contours in the form of at least one recess or at least one protrusion which are designed such that they engage with corresponding support contours of the support section such that the contours of the support edges have mutually facing and / or facing walls are formed so that they are in the movement path of the respectively associated support contour of the storage section in the direction of the axis of rotation.

FIG. 1 shows a nonwoven winder 1 according to an embodiment of the invention. The components which are immaterial to the invention are not explained further.

The nonwoven winder 1 essentially comprises two frame walls 13, which are combined via unspecified connectors to form a frame which receives or holds all other functional elements of the nonwoven winder 1.

The frame walls 13 have in a right-hand area a magazine 2 in which there are two winding shafts 10.

Furthermore, the nonwoven winder 1 comprises on each frame wall 13 a recess which defines a waiting position 3 for a winding shaft 10. Since the winding shafts 10 are held on both sides by a respective frame wall 13, a waiting position 3 is thus realized by means of the two frame walls 13. The frame walls 13 thus form by means of the waiting position 3 a holding section for a winding shaft 10 to be wound.

In the waiting position 3, the winding shaft 10 arranged therein is set in rotation by means of a clamping portion 11. The Andrehabschnitt 11 contacts the area of the winding shaft 10, which serves to receive fleece. Ie. not the entire winding shaft 10 is set in rotation but only here centrally arranged thus winding section 62, the circumference forms the actual winding surface and is part of a rotary section 60 of the winding shaft.

In order to transfer a winding shaft 10 from the magazine 2 to the waiting position 3, a transport section 8 is provided.

Furthermore, the nonwoven winder 1 has a Anwickelposition 4, which is located in a bending region, as seen along the axis of rotation of a contact roller 7 of the web unwinder 1, between the frame wall 13 and contact roller 7. The contact roller 7 leads in a known manner, the incoming web to the winding shaft 10 to be wound zoom.

For automatically changing the nonwoven fabric from one winding shaft 10 to the next, a separating section 12 is provided.

Furthermore, the nonwoven winder 1 has a winding position 5, which by means of a support element 14 arranged here on the left between the frame wall 13 and Contact roller 7 is realized. In this position 5, the corresponding winding shaft 10, which has already taken up fleece in the Anwickelposition 4, finally wound.

For transporting the winding shaft 10 from the waiting position 3 via the Anwickelposition 4 to the winding position 5, a movement portion 9 and a locking portion 40 are used.

After winding the respective winding shaft 10, the fleece is separated by means of the separating section 12, and the wound winding shaft 10 is moved by means of a winding and Ausschubabschnitts 50 in a Ausschubposition 6 of the nonwoven winder 1.

FIG. 2 shows the nonwoven winder 1 in the context of the winding shafts 10 contacting or attacking elements.

The winding shaft 10 arranged on the right rests on upwardly facing edges 13a of the frame walls 13. Below a transport lever 30 of the transport section 8 not shown is shown. The transport lever 30 causes by means of swinging up first, that the winding shaft 10 is lifted from the frame wall 13 and in the direction of the left end of the transport lever 30, and then by lowering or pivoting back of the transport lever 30, that the winding shaft 10 is pivoted to the waiting position 3.

If the winding shaft 10 is in the waiting position 3, and if it has been turned on, or if it should be turned on, it is gripped by means of the locking section 40 at both ends and by means of the not shown here Moving portion 9 along the frame wall 13 on the Anwickelposition 4 moves to the final winding position 5. In this case, the winding shaft comes to rest on a surface 14 a of the respective support element 14.

After reaching the winding position 5, the locking portion 40 lets go of the winding shaft 10, and a lever 55 of the winding and Ausschubabschnitts 50 of the web winder 1 presses the winding shaft 10 against the contact roller 7 to be finally wound. If the winding shaft 10 is wound, the lever 55 pivots according to FIG. 2 opposite to the clockwise direction and pushes the wound shaft 10 in the direction of Ausschubposition 6 along the support elements 14 shown here away from the contact roller 7.

For reasons of clarity, the contact roller 7 is shown floating in relation to the other nonwoven winder 1. The reason is that the necessary storage and drive elements for the contact roller 7 are required, but not essential to the invention.

FIG. 3 shows a winding shaft 10 located in the magazine 2 of the web unwinder 1.

The winding shaft 10 is shown in the frame in the cutout at one end and lies with a running section 110 here on the corresponding running surface 13a of the frame walls 13. The tread 110 is exemplarily formed as a groove-like and circumferential recess. The running portion 110 in this case has a groove bottom as a running surface 112, which is bordered on both sides by two edges 111. The tread 112 and, by way of example, also the edges 111 are formed as an example circumferential. Thus, it is the winding shaft 10 possible by means of the running portion 110th on the frame wall 13 or its tread 13a or on the tread 14a of the associated support member 14 to roll along. The edges 111 prevent that the winding shaft 10 can move along its axis of rotation.

The running section 110 is formed on a functional element 100. The functional element 100 accommodates a bearing element 61 and a transport element 201 in a freely rotatable manner. The functional element 100 is thus designed as a sleeve-like element which has a passage opening which extends along the axis of rotation of the winding shaft 10.

The storage section 61 is rotatably arranged in the winding element 62 of the winding shaft 10 or formed integrally therewith. Thus, it is the functional element 100 possible to rotate independently of the rotatably received elements 61, 62 and 201 along the frame wall 13 and to roll it.

Thus, it is possible to set the winding element 62, as described above, by means of Andrehabschnitts 11 in rotation, although the functional element 100 is quiet, for example, in Andrehposition 3 on the tread 13a.

FIG. 4 shows a winding shaft 10 located on the transport lever 30 of the nonwoven winder 1.

The winding shaft 10 is by means of a transport section 120 on a corresponding running surface 31 of the transport lever 30. The transport section 120 here also preferably comprises a groove-like recess. The recess has a groove bottom, which serves as a running surface 121 on the running surface 31. The tread 121 is enclosed by facing edges 123 formed on a respective projection 122. The groove base 121 and the projections 122 are preferably formed circumferentially.

The transport lever 30 is preferably formed on its side facing the winding shaft 10 substantially complementary to the transport section 120. Ie. the tread 31 is enclosed on both sides by two edges 32 which extend away from the tread 31 away from one another. The width of the tread 31 is preferably slightly smaller than the width of the tread 121.

This makes it possible, when placing the winding shaft 10 on the transport lever 30 and when driving under the winding shaft 10 by means of the running surface 31 of the transport lever 30 to center the winding shaft 10 on the respective transport lever 30 and thus bring it into the correct position.

FIG. 5 shows a winding shaft 10 gripped by the locking portion 40 of the web unwinder 1.

The locking portion 40 comprises a carriage 42 and a locking lever 43. The carriage 42 is moved by the aforementioned movement portion 9, while the winding shaft 10 is held. The locking lever 43 is pivotally attached to the carriage 42. At its outer, here front end of the locking lever 43 has a roll holder 44. Its roller 41 is freely rotatable about an axis parallel to the axis of rotation of the winding shaft 10 and abuts a locking surface 131 of a locking portion 130 here of the functional element 100.

On the carriage 42, two roller supports 44 are also formed, which are analogous to the roller holder 44 on the locking lever 43 and each carrying a roller 41. Of these two roller holders 44, only the lower one is visible here, the other one is located behind the winding shaft 10.

By means of the three rollers 41, the winding shaft 10 is securely gripped in the region of the functional element 100 by means of the locking surface 131. The locking portion 130 is exemplified as a corner-like recess. The locking surface 131 has a smaller outer diameter than the immediately adjoining region of the functional element 100. The adjoining the locking surface 131 here left edge 132 extends away from the locking surface 131 and preferably also away from a cover member 63. The edge 132 is thus formed as a slope. This allows the rollers 41 to securely reach the locking surface 131 when gripped. The three rollers 41 are preferably arranged uniformly distributed about the winding shaft. Ie. Connecting lines between the centers of rotation of two rollers 41 each to the center of rotation of the gripped winding shaft 10 in pairs form an angle of 62 °.

FIG. 6 shows a located on a frame wall 13 of the web unwinder 1 and in engagement with the lever 55 of the winding and Ausschubabschnitts 50 winding shaft 10 in two views. According to FIG. 6a is the winding shaft 10 in the winding position 5. According FIG. 6b is the winding shaft 10 by means of the winding and Ausschubabschnitts 50 slightly away from the winding position 5 in the direction of not visible here, left arranged Ausschubposition 6 moves.

The winding and Ausschubabschnitt 50 essentially comprises the lever 55, which comprises at its upper, free end here a preferably attached fastening element 52.

On the fastening element 52 are two rollers 51, 51 freely rotatable about an axis parallel to the axis of rotation of the contact roller 7, not shown here. By means of these two rollers 51, 51, the lever 55 is able to urge the winding shaft 10 over a surface 141 of its winding and Ausschubabschnitts 140 in the direction of Ausschubposition 6 here along the surface 14a of the support member 14. The fastening element 52 protrudes somewhat in the direction of the winding shaft 10 in order to prevent the winding shaft from coming off the surface 14a here. As a result, the winding shaft 10 is secured during winding against falling out.

In this case, the lever 55 pivots in FIG. 6a clockwise, and eventually comes in FIG. 6a lower roller 51 with the winding shaft 10 and its surface 141 in contact.

At the same time or on further movement of the winding shaft 10 away from the contact roller 7 or at the end of the winding of the winding shaft 10, the lever 55 comes by means of in FIG. 6b visible, front roller 51 with the edge 141 in contact. By pivoting the lever 55 according to FIG. 6b counterclockwise, the winding shaft 10 is moved over the surface 141 along the support member 14 here to the left. This roller 51 is now also attached via a roller holder 53 to a fastening element 54 which is preferably mounted analogously to the fastening element 52 on the lever 55.

Since the winding shaft 100 is already securely mounted on the frame wall 13 or the support element 14 against movement along its axis of rotation due to the groove-like running section 110, it is sufficient that only the surface 141 is present. Projecting edges are not required.

FIG. 7 shows a voltage applied to the end stop 20 of the web unwinder 1 winding shaft 10. D. h. the winding shaft 10 is in Ausschubposition. 6

In this case, the winding shaft 10 is preferably by means of the surface 141 on a stop element 22 of the end stop 20 at. This also has a fastening element 21 which is fixed to the frame wall 13 and on which the stop element 22 is mounted projecting in the direction of winding shaft 10. The stop element 22 is preferably formed of an elastic or shock-absorbing material.

FIG. 8 shows one end of the winding shaft 10 in the region of one of its two ends in a view transverse to the axis of rotation of the winding shaft 10. This extends horizontally from left to right. The winding element 62 is adjoined by the bearing element 61 inserted therein in a rotationally fixed manner. On this layer element 61, a guide element 160 is placed at its end facing away from the winding element 62. The guide element 160 opens freely rotatable in the functional element 100. In the guide element 160 facing away from the end of the functional element 100, the transport element 201 is freely rotatably inserted. At the end of the transport element 201 facing away from the functional element 100, the cover element 63 adjoins. Alternatively, the elements 61 and 160, 160 and 101 or 63 and 101 may be formed in pairs or integrally with each other.

The invention is not limited to the embodiment described above.

Each type of recess may be replaced by a projection, if the corresponding counter element is consequently designed as a recess or groove.

Each groove-like recess can be realized as a corner-like recess when the corner-like recesses at the opposite ends of the winding shaft 10 facing each other or away from each other.

The edges do not have to be inclined but can also be arranged perpendicular to the respective groove base.

The shape of the recesses or projections may have any other shape, for example in crowned execution.

The variety of elements can be limited. For example, the bearing element 61 and the guide element 160 may be integrally formed.

The recesses can all be formed like a corner, so that in extreme cases, a stair-like structure, seen transversely to the axis of rotation of the winding shaft 10, arises.

Also, individual recesses can take over several functions, so that reduces the number of recesses.

Also, some parts may be integrally formed with each other, such as the winding element and the storage portion 61 with some or all other components included in the functional element 100.

The recesses must be formed only at one end of the winding shaft 10, as may be the case for example for the transport section 120.

As a result, the invention provides an easy-to-install and relatively few-part way of making a winding shaft 10.
