In order to prepare a fiber package holder, which can also be operated safely and reliably with non-standard spinning bobbins of different lengths, it is planned to install at least one limiter between the application position and the lowering position in the receiving area with a possibility of movement so that the receiving area in the application position is shortened for the respective reception of a shortened spinning bobbin, and in the lowering position a standard spinning bobbin can be located in the receiving area above the limiter. The invention further relates to a twisting machine, in particular a ring twister, with at least one fiber package holder and a method of using the fiber package holder.

Description

The invention relates to a fiber package holder for a twister, in particular a ring twister, with a receptacle rotatable about a support axis, with a receiving area for fitting a spinning bobbin on the reel. The invention further relates to a twister, in particular a ring twister, with at least one fiber pack holder. Finally, the invention relates to a method of using a fiber package holder.

Fiber pack holders in modern technologies can have various designs, for example, they are presented in the publication CN 204369314 U, and are used to install a spinning spool with a twisted thread or filament with the possibility of rotation. For this, standard spinning spools are usually located on the fiber package holder and, thanks to the use of the fiber package holder, remain stable and reliable.

However, smaller spinning spools are also used which are shorter in the axial direction of rotation of the fiber package holder, which results in the spinning spool being displaced in this axial direction. Because of this, it is not possible to determine the exact location of the spinning bobbin, making controlled and safe use impossible. This can impair the operation of a twister having a fiber pack-holder, and also lead to blockage of the spinning spool, as a result of which the threads or filament break and the production process is interrupted.

Therefore, the aim of the present invention was to provide such a fiber package holder, which can also be safely and reliably used for non-standard and different length spinning spools.

The task according to the invention is solved by means of the fiber package holder according to claim 1, the twisting machine according to claim 11, and also the method according to claim 13. Preferred additional embodiments of the invention are given in dependent claims.

The fiber package holder according to the invention for a twister, in particular a ring twister, comprises a mounted, rotatable receiver having a receiving area for accommodating a spinning spool on the receiver, wherein at least one stopper is installed between the application position and the lowering position in the receiving area. movable in such a way that in the position of application the receiving area is made shortened for the corresponding reception of a shortened spinning coil, and in the position of lowering the limiter, the receiving area is made with the possibility of placing a standard spinning coil over the limiter, and the limiter at the end opposite the receiving area contains a lock, and the receptacle comprises two latch mounts with which the stopper is fixed in an application position and a lowering position.

The invention further relates to a twister, in particular a ring twister, which comprises at least one fiber package holder according to the invention.

Finally, the invention relates to a method of using a fiber package holder according to the invention for a twister, which comprises a receiver mounted, rotatable about a main axis, having a receiving area for accommodating a spinning bobbin on the receiver, and also at least movable between an application position and a lowering position, a limiter located in the receiving area, so that in the application position the receiving area is shortened for the corresponding reception of a shortened spinning bobbin, and in the lowering position in the receiving area, the standard spinning bobbin is arranged to be positioned above the limiter, and the method includes the steps of determining the length of the spinning bobbin that is shifted to the receiver, and checking that the length of the spinning spool matches the prescribed standard length. If the spinning bobbin corresponds to the standard length, then all the stops are moved towards the drop position, and if the spinning bobbin used is shorter than the standard spinning bobbin, then separate stops are removed to match the receiving area of the receiver to the length of the spinning bobbin. Then the spinning bobbin is shifted towards the receiver.

The inventor is aware that for the safe installation and operation of the spinning bobbin on the fiber package holder, there is a limiter for each use. Up to this point, the pack holder could not be used with a shorter spinning bobbin, since previously a short spinning bobbin could not be centered in the desired position. Alternatively, self-created temporary spacers were used, which, however, did not guarantee satisfactory results, and furthermore, these spacers had to be individually adjusted to the respective spinning bobbin. The placement of at least another limiter in the receiving area, on the contrary, contributes to a particularly simple and stable fixation of the short spinning bobbin, while still being advantageous is the possibility of cheaper production of the fiber package holder. Furthermore, it is advantageous if the at least one limiter can be actuated without the use of additional tools, whereby the fiber package holder can be fitted particularly easily and quickly to the spinning spool being used. It is particularly advantageous that, by using several limiters, a large number of non-standard spinning bobbins and bobbins of different lengths can be reliably and safely handled by means of a fiber package holder.

A fiber package holder is to be understood to mean any device which is intended to receive a spinning bobbin and also to wind up the bobbin or thread, filament or the like which is on the spinning bobbin. In this case, at least part of the fiber package holder is located inside the spinning bobbin or the spinning bobbin is located above a part of the fiber package holder. Such a fiber package holder is also often referred to by the English name Creel Basket, and is therefore particularly preferably used for glass fiber filament. Particularly preferably, at least one fiber package holder and particularly preferably several fiber package holders are simultaneously arranged on the twister. Such a twister can in principle mean any machine processing fibres, twisted yarns, filaments, etc., where the twister preferably means a ring twister, in particular a high performance ring twister or cord machine.

The spinning bobbin can be any bobbin on which a thread, twisted thread or filament of fibrous material, synthetic monofilament, glass, plastic or non-woven material is wound for further processing. Preferably, the spinning spool is also a filament or fiber holder. Winding can be any. Also preferably, the spinning bobbin has a conical or cylindrical shape, and a thread or the like is particularly preferred. wound on the outside of the spinning spool. Further, the spinning bobbin preferably has a cylindrical opening for accommodating the fiber package holder in the receiving area.

The receiver can in principle be made in the form of a whole element or in the form of a structural group of several elements. In this case, the receiver has a receiving area for winding the spinning bobbin by rotation, the spinning bobbin being at least partially, preferably completely, located on the receiver, particularly preferably in the receiving area. Particularly preferably, the receptacle in the receiving area has a receptacle surface at least partially against the spinning bobbin.

In principle, the receiver rotates around the main axis. Preferably, the receiver is rotatably mounted with a main axis. In this case, the main axis is mounted centrally in the fiber package holder or centrally inside the receiving area, for positioning and fixing the tubular or cylindrical spinning bobbin during rotation. The main axis can be made both as an element forming the axis and as a geometric axis, while other elements that do not lie on the same axis or pass through the geometric axis can contribute to the rotation. Preferably, however, the main axis is in the form of an element located along the geometrical axis of rotation, this element also having other functions and particularly preferably being one of the main elements of the multi-part receiver.

The terminator can first of all mean any element or any mechanism designed to be connected to the spinning bobbin, and in this case it is particularly preferred to prevent the spinning bobbin from moving along the main axis of the receiver, i.e. in the axial direction. Although the stopper may be made of any material, the stopper, particularly preferably any stopper of the fiber package holder, is made of the same material as the receptacle and/or of plastic. In order to be particularly easy to manufacture and to ensure maximum strength and minimum susceptibility to failure, the stopper is one-piece.

Particularly preferably, the fiber package holder has a plurality of stops, with all of the stops preferably having an identical structure and particularly preferably the same shape, size, length and/or made of the same material. In principle, several stops or even groups of several stops can be located around the perimeter of the receiver, in particular in the reception area, and particularly preferably in the same position relative to the axial direction of the main axis.

According to the invention, at least one stopper is located between the application position and the lowering position in a movable, particularly preferably movable manner. In the application position, the stopper protrudes above the receiver surface in the receiving area, thus the stopper reduces the maximum length of the receiving area provided for a standard spinning bobbin, and therefore a shorter bobbin can be located in the receiving area compared to a standard spinning bobbin.

In the lowering position, at least one stopper is located below, so that the stopper does not shorten the receiving area, and accordingly the spinning bobbin can protrude above the lowered stopper on the receiver in the receiving area. By protruding arrangement is meant such an arrangement in which the spinning bobbin is located above the stopper, which is in the receiving area in the lowering position, i.e. the limiter is preferably located inside the spinning spool together with the receiver section.

A preferred embodiment of the fiber package holder according to the invention is one in which the receiving area at the end of the receiver is limited by a strong end barrier.

- 2 039792 limit of movement, and at least one movable stop is located in such a way that it forms a new end stop of movement of the shortened receiving area in the application position, due to which it is quite simple to match the length of the receiving area with the length of the spinning bobbin. In this case, at least one limiter can preferably be located in the direction in which the spinning bobbin can move on the receiving area of the receiver, in front of the end limiter. Further, in the case of an end limit stop, which is limited by the maximum receiving area, it is not a displaceable or driven to the lowering position, but a fixed stop.

In a preferred further embodiment of the fiber package holder according to the invention, several stops are arranged at equal distances from each other in the receiving area of the receiver, which makes it easy to match the length of the receiving area with spinning bobbins of different lengths. In addition, the limiters can also be placed at different distances from each other or at different positions, which correspond to the length of the spinning bobbin, so that particularly precise matching with different spinning bobbin can be obtained. Preferably, 1-10 stops are arranged, particularly preferably 2-8 stops, very preferably 4-6 stops, and particularly preferably 5 stops per receiver and/or group of stops. In this case, the receiver may comprise several groups of limiters, which are particularly preferably located on the receiver parallel to each other and/or around the perimeter. There may be any number of delimiters, which may also be located along the entire length of the receiving area and/or receiver.

According to a preferred embodiment of the fiber package holder according to the invention, several stops are arranged one after the other in the axial direction of the main axis in the receiving area, so that different lengths of the spinning bobbins can be adapted particularly easily, in particular if all movable stops or all stops of a group in the preferred embodiment are arranged on the same line on the surface of the receiver. In this case, the limiters can particularly preferably be arranged coaxially or at the same distance from the main axis.

A further preferred embodiment of the fiber package holder according to the invention is one in which each stopper comprises a spinning bobbin located in the receiving area and in contact in the receiving area with a surface of the stopper, which is particularly preferably flat and/or located radially and tangentially to the main axis, with with which it is possible to obtain a particularly stable, planar device, thus preventing axial displacement of the spinning bobbin on the receiver. Further, the surface of the limiter extends over the height of the side of the limiter protruding from the receiver and/or over the entire width of the side of the limiter.

In a preferred embodiment of the fiber package holder according to the invention, all stops in the lowering position are completely lowered into or below the surface of the receptacle in the receiving area, whereby the spinning bobbin can protrude above the receiving area of the receptacle particularly easily and without interference from the stopper. Particularly preferably, the stops fit snugly against the surface of the receptacle and can be lowered, in particular, in such a way that neither a recess nor an opening is formed, only a part of the stopper protrudes outwards, thus no material is collected in front of the opening or in the opening for the stopper.

In principle, the shifting limiter can be set in any way in the application position and in the lowering position. For example, this may be done by kinematic closure and/or dynamically coupled. However, the fiber package holder according to the invention should preferably observe a dwell time each time the stopper is lowered into the application position and/or into the lowering position, whereby it is particularly easy to place the stopper, on the one hand, in the appropriate position, in particular without the use of equipment, and on the other hand side, it is also particularly easy to pull it out of this position again to adjust the stop or stops.

To this end, the stopper preferably further comprises a latch at the end opposite the receiving area, and the receiver comprises at least one, preferably two latch holders, with which the stopper is firmly fixed in the application position and/or the lowering position. In this case, the latch can be made in any way. Preferably, the latch is a one-piece element with a stopper, and particularly preferably, the latch is a stopper tip. Further preferably, the retainer and particularly preferably the end of the retainer with the retainer are displaced towards the retainer receptacles, wherein also the displacement area of the retainer is particularly preferably integral with the retainer and/or the remainder of the restrictor. The receptacles corresponding to the latch can also be made in any way, the receptacles for the latch being preferably made in the form of recesses and/or in one piece with a part of the receiver. It is also preferred that both retainer receptacles are positioned one above the other in the receptacle.

Thus, in a preferred embodiment of the fiber package holder according to the invention, the stopper extends completely through the part of the receptacle around the stopper, so that the stopper latch is retained in its lowering position by the bottom edge of the receptacle, or the underside of the receptacle forms in this area a receptacle for the retainer, thus simplifying the design. With such a receiver directed towards the lowering position, open in the region of the limiter, it is preferable that the limiter, in particular with a kinematic lock, is protected from leaving the lowering position, i.e. towards the inside of the receiver.

According to a preferred further embodiment of the package holder according to the invention, at least one stopper is movable and is located radially to the main axis, the guides preferably comprising at least one guide groove located in the receiver and one corresponding guide link of the stopper, whereby a reliable adjustment can be carried out very easily. . At the same time, the restrictor, at least preferably in the shear direction, at least in the area located inside the part of the receiver, has a constant cross-sectional area, and the cross-sectional area of the opening of the receiver for the restrictor basically matches the shape or cross-sectional area of the restrictor.

In a preferred embodiment of the fiber package holder according to the invention, a motorized individual drive of the fiber package holder is provided, with which the receptacle, at least with a limiter, rotates around or with the help of a main axis, whereby it is particularly easy to individually adjust the fiber package holder and adjust the speed of rotation of the receiver with the spinning coil located on it and its length and diameter.

Also in a preferred embodiment of the fiber package holder according to the invention, the receptacle comprises a plurality of clamping elements, evenly distributed around the perimeter, located on the main element, the clamping elements being movable in the radial direction, for holding the spinning spool in a dynamically coupled manner, and preferably at least one limiter, particularly preferably all limiters are located on the clamping elements. In this case, the limiters are particularly preferably located directly on the clamping elements.

Alternatively, at least one stopper, preferably part of several stoppers, and especially preferably all of the stoppers, can also be located on the base element, and in this case particularly preferably between two clamping elements. In this case, at least one stop, especially preferably all stops, is designed in such a way that the stop in the application position in each possible position of the clamping elements in the receiving area protrudes above the surface of the clamping elements, so that the spinning bobbin, regardless of the installation position of the clamping elements, can always be connected. with the limiter, and in particular with the surface of the limiter.

Finally, a preferred embodiment of the fiber package holder according to the invention provides that all stops are of a different color and are particularly preferably made of materials of different colors, particularly preferably of plastic, in order to better distinguish the stops and to protect against operational errors.

A preferred additional embodiment of the method for using a fiber package holder provides that a limiter is selected from several stops to be placed in the application position in such a way that the length of the receiving area, shortened by the stop, corresponds to the length of the spinning spool located on the receiver. Also additionally or alternatively, it is possible to choose a stopper placed in the application position in such a way that the center of the shortened spinning bobbin is located in the middle of the unshortened receiving area.

An example of a fiber package holder according to the invention is shown in more detail below with the help of the drawings. Figures show:

fig. 1a is a perspective view of a section of a fiber package holder with five stops in a lowering position;

fig. 1b is a perspective view of a section of the fiber package holder of figure 1a with five stops in the application position;

fig. 2 - side section through the fiber pack holder in the region of the limiter.

In the shown in FIG. 1 of the fiber pack holder 1 of the high-performance ring twister, which is partially shown in FIG. 1a, one receptacle 2 can be rotated about a main axis in order to be able to lead the yarn from the spinning spool located in the receptacle 2 area 3 to a high-performance ring twister. At the same time, the pack holder 1 for the fiber contains an electromotive unified drive unit, which can rotate the receiver 2 over the main axis.

The receiver 2 contains the main element 12 containing the main axis, as well as several evenly distributed clamping elements 13 located along the outer perimeter of the receiver 2, the clamping elements 13 being movable relative to the main axis, radially to the main element 12, for dynamically connected fixation of the spinning coil in the area 4 039792 reception with receiver 2. Each clamping element 13 contains at the end a fixed end limit stop 5 of movement, which limits the end of the reception area 3 in the direction in which the spinning bobbin moves towards the receiver 2. The length of the reception area 3 corresponds to the length of the standard spinning bobbin, and the function of the fixed travel end stops 5 is a defined and repeatable positioning of the spinning bobbin on the fiber pack holder 1.

Also, for the safe placement of spinning bobbins, which are shorter than standard bobbins, in a certain place, on the receiver 2, in particular on the clamping element 13, several other stops 4 are located. The individual stops 4 are at a constant distance from each other and are located on the surface of the clamping element 13 in the axial direction or coaxial to the main axis and along the length of the receiving region 3.

If a standard, long spinning bobbin is used, then all the other stops 4 are in a lowering position (see Fig. 1a) in which the other stops 4 are lowered directly into the receptacle 2, so that the spinning bobbin can be positioned above the stops 4 or protrude over the entire area 3 doses. However, the other stops 4 are movably independent of one another and can accordingly protrude from the application position from the surface 7 of the receptacle 2 (see FIG. 1b), thus the first stop 4 which is in the application position when the spinning bobbin is shifted towards the receptacle 2 or to the receiving area 3 forms a new end stop, since the spinning bobbin cannot extend beyond the fixed end stop 5. To do this, each limiter 4 has a flat surface 6 of the limiter.

In order to fix the respective limiter 4 in the lowering position and in the application position, each limiter 4 at the lower end located inside the receptacle 2 contains a tip as a retainer 9, which is pre-displaced in such a way that it is connected to the receiving devices in the lowering position and in the application position 10a, b for the latch in the receiver 2 (see Fig. 2). In this case, the holders 10a for the latch for the application position are made in the form of a recess in the receiver 2, in particular in the clamping element 13. The holder 10b for the latch for the lowering position is the lower side of the receiver 2 in the region of the limiter 4.

Each stopper 4 is located in an opening of the receiver 2, particularly preferably of the clamping element 13, which has a cross section corresponding to the cross section of the stopper, so that the stopper 4, during displacement from the lowering position to the application position and back, passes through the hole, and to improve the guidance of the stopper 4 contains the guide link 11.

In order to prevent subsequent movement of the stopper 4 from the lowering position further inside the receptacle 2 and below the surface 7 of the receptacle 2, each stopper 4 has an upper protective surface 14 that is larger than the cross-sectional area of the remaining parts of the stopper 4, so that it comes into contact with the surface 7 or a corresponding recess in surface 7 of the clamping element 13 and prevents subsequent shift.

In order to better distinguish the stops 4 from each other, preferably all the stops 4 have different colors, most preferably the colors of the stops 4 correspond to the colors of the materials of the respective and suitable spinning bobbins.
