Description

The invention relates to a spinning bobbin carrier for a twisting machine, in particular a ring twisting machine, with a receiving body rotatably mounted about a carrier axis with a receiving area for arranging a spinning bobbin on the receiving body. Furthermore, the invention relates to a twisting machine, in particular a ring twisting machine, with at least one spool bobbin. Finally, the invention relates to a method for using a spool bobbin.

Spinning reel carriers are in a variety of configurations from the prior art, for example from the publication CN 204 369 314 U , are known and are used to rotatably support a spinning bobbin with thread or filament to be twisted. For this purpose, the standardized spinning bobbin is typically arranged on the spinning bobbin carrier and held in a stable and secure manner by the spinning bobbin carrier during use.

However, spinning bobbins are also used which are smaller and, in particular, shorter in the axial direction of the rotatable mounting of the spinning bobbin carrier, as a result of which the spinning bobbin can be displaced in this axial direction. However, this means that the exact position of the spinning bobbin is no longer determined, making controlled and safe use impossible. The operation of a twisting machine having the spinning bobbin can be impaired, up to a blocking of the spinning bobbin, whereby the thread or the filament breaks and the operation is interrupted.

The invention is therefore based on the object of providing a spool bobbin which can be operated safely and reliably even with non-standardized spinning bobbins of different lengths.

The object is achieved according to the invention by a spinning bobbin support according to claim 1, a twisting machine according to claim 12 and a method according to claim 13. Advantageous developments of the invention are specified in the dependent claims.

The spinning reel carrier according to the invention for a twisting machine, in particular a ring twisting machine, has a receiving body rotatably mounted about a carrier axis with a receiving area for arranging a spinning bobbin on the receiving body, wherein at least one stop between the use position and a retracting position is adjustably arranged in the receiving area such that in the use position of the receiving area is shortened in the axial direction of the carrier axis for the adapted take-up of a shortened spinning bobbin and in the lowering position a regular spinning bobbin can be arranged in the receiving area so as to project beyond the stop.

Furthermore, the invention relates to a twisting machine, in particular a ring twisting machine, which has at least one spinning bobbin according to the invention.

Finally, the invention relates to a method for using a spinning bobbin carrier for a twisting machine, with a receiving body rotatably mounted about a carrier axis with a receiving region for arranging a spinning bobbin on the receiving body and at least one stop arranged in the receiving region such that it can be adjusted between a use position and a lowering position such that in the use position the receiving area is shortened to suitably accommodate a shortened spinning bobbin and in the lowering position a regular spinning bobbin can be arranged in the receiving area so as to project beyond the stop, the method first determining the length of a spinning bobbin to be pushed onto the receiving body and checking whether the spinning bobbin corresponds to an intended, standardized length. If the spinning bobbin corresponds to a standardized length, all stops are moved into the lowering position and if the spinning bobbin is shorter than a standardized spinning bobbin, a single stop is pulled out to adapt the receiving area of the receiving body to the length of the spinning bobbin. Finally, the spinning bobbin is pushed onto the take-up body.

The inventor has recognized that a stop is helpful in any case for the secure arrangement and guidance of a spinning bobbin on the spool bobbin. So far, this could not be used with shorter spinning bobbins, because otherwise the shortened spinning bobbin would no longer be centered at the desired position. As an alternative, the user used self-designed and provisional spacers, which, however, also did not guarantee satisfactory results and also had to be adapted to the respective spinning bobbin. The arrangement of at least one further stop in the receiving area, on the other hand, enables a particularly simple and stable fixing of the shorter spinning bobbin, with it still advantageously being possible to produce the spinning bobbin carrier inexpensively. In addition, it is advantageous if the at least one stop can be actuated without a tool, as a result of which a particularly simple and rapid adaptation of the spool bobbin to the spool to be used is possible. In particular when using several stops, one A large number of non-standardized spinning bobbins of different lengths can be used safely and reliably by means of the spool bobbin.

A spool bobbin is initially understood to mean any device which is provided for receiving a spinning bobbin and for unwinding the bobbin or for providing the thread, filament or the like located on the spinning bobbin. In this case, at least part of the spool bobbin is arranged in the interior of the spinning bobbin or the spool is arranged over part of the spinning bobbin carrier. Such a spool bobbin is also often referred to with the English name "Creel Basket" and is used in particular for glass filament yarns. In particular, there is at least one spool bobbin and, with particular preference, a plurality of spool bobbins are simultaneously arranged on a twisting machine. Such a twisting machine can in principle be any machine processing threads, twists, filaments or the like, the twisting machine preferably being a ring twisting machine, in particular a high-performance ring twisting machine, or a cabling machine.

A spinning bobbin can be any bobbin on which a thread, a thread, a filament or the like made of fiber material, wire, glass, plastic or a composite material is wound for further processing. The spinning bobbin is therefore preferably a yarn or thread carrier. Any winding can be present. The spinning bobbin also preferably has a conical or cylindrical shape, and particularly preferably the thread or the like is wound on the outside of the spinning bobbin. Furthermore, the spinning bobbin preferably has a cylindrical opening for arrangement on the receiving area of the spool bobbin.

The receiving body can in principle be formed as a one-piece component or as an assembly of several components. The receiving body with the receiving area is provided for the rolling unwinding of the spinning bobbin, the spinning bobbin being able to be arranged at least in sections, preferably completely, on the receiving body, in particular in the receiving area. The receiving body particularly preferably has a receiving surface in the receiving area for at least partial contact with a spinning bobbin.

Basically, the receiving body is rotatable about a carrier axis. The receiving body is preferably fixed rotatably by means of the carrier axis. The carrier axis is arranged in the center of the spool bobbin or in the center of the receiving area in order to enable positioning and holding of a tubular or cylindrical spool in particular during rotation. The carrier axis can be both an axis formed as a component and only a geometric axis, while the rotatability can be provided by other components that are not arranged axially or through the geometric axis. However, the carrier axis is preferably formed as a component running along the geometric axis of rotation, this component also having further functions and in particular being able to form the base body of a multi-piece receiving body.

The stop can initially be any component or mechanism that is intended to be brought into contact with a spinning bobbin and, in particular, a displacement of the spinning bobbin on the receiving body along the carrier axis, ie in the axial direction, to prevent. Although the stop can be formed from any material, the stop and in particular each stop of the spool bobbin is preferably formed from the same material as the receiving body and / or from a plastic. In order to enable particularly simple manufacture and to ensure the greatest possible durability and the lowest possible susceptibility to errors, the stop is preferably formed in one piece.

The spool bobbin particularly preferably has a plurality of stops, all stops preferably being identical to one another and particularly preferably having an identical shape, size, length and / or an identical material. In principle, a plurality of stops or even groups of a plurality of stops can be arranged over the circumference of the receiving body, in particular in the receiving region, and particularly preferably in each case in the same position with respect to an axial direction of the carrier axis.

According to the invention, the at least one stop between an in-use position and a retracted position is adjustable, particularly preferably displaceable. In the use position, the stop protrudes from the surface of the take-up body in the take-up area, so that the stop shortens the maximum length of the take-up area, which is provided for a standardized spinning bobbin, and thus a shorter spinning bobbin compared to the standardized spinning bobbin can now be safely arranged in the receiving area .

In the retracted position, the at least one stop is lowered to such an extent that the stop no longer shortens the receiving area and, accordingly, a spinning bobbin can be arranged so as to project above the lowered stop on the receiving body in the receiving area. A superior arrangement is understood to mean that the spinning bobbin is above that in the receiving area arranged and located in the retracted stop, ie that the stop is preferably located together with a portion of the receiving body in the interior of the spinning bobbin.

A preferred embodiment of the spool bobbin according to the invention provides that the receiving area is delimited at one end of the receiving body by a fixed end stop, and the at least one displaceable stop is arranged such that it forms a new end stop of the shortened receiving area in the use position, which makes it easier The length of the receiving area can be adapted to the length of the spinning bobbin. The at least one stop is preferably arranged in front of the end stop in a direction in which a spinning spool is pushed onto the receiving area of the receiving body. Furthermore, the end stop, which delimits the largest possible receiving area, is not a movable stop or one that can be brought into a retracted position, but a fixed stop.

In a preferred development of the spool bobbin according to the invention, a plurality of stops, in particular at the same distance from one another, are arranged in the receiving area of the receiving body, as a result of which the length of the receiving area can be easily adapted to spinning bobbins of different lengths. In addition, it is also conceivable to arrange the stops at a distance from one another or at positions which correspond to the known lengths of spinning bobbins, so that a particularly precise adaptation to different spinning bobbins is achieved. Between one and ten stops, particularly preferably between two and eight stops, very particularly preferably between four and six stops and particularly preferably exactly five stops are preferably arranged on the receiving body and / or in a group of stops. The receiving body can have several groups of stops, which are then particularly preferably arranged on the receiving body parallel to one another and / or along the circumference. In principle, any number of stops is conceivable, which in particular can extend over the entire length of the receiving area and / or of the receiving body.

According to an advantageous embodiment of the spool bobbin according to the invention, a plurality of stops are arranged one behind the other in the receiving area in the axial direction of the carrier axis, so that adaptation to different lengths of the spool bobbins is particularly easy, in particular if all the stops to be moved or all the stops of a group in a particularly advantageous embodiment are in a line are arranged on the surface of the receiving body. The stops are in particular arranged coaxially or at the same distance from the carrier axis.

Also preferred is an embodiment of the spool bobbin according to the invention in which each stop has a stop surface which can be brought into contact with the spool bobbin to be arranged in the receiving area, which is particularly preferably planar and / or extends radially and tangentially to the carrier axis, as a result of which a particularly stable, flat contact and thus a good protection against axial displacement of the spinning bobbin on the receiving body is achieved. Furthermore, the stop surface preferably extends over the entire height of one side of the stop protruding from the receiving body and / or over the entire width of one side of the stop.

In an advantageous embodiment of the spool reel carrier according to the invention, all stops in the retracted position are completely lowered into or below the surface of the receiving body in the receiving area, as a result of which a spinning bobbin can be pushed onto the receiving area of the receiving body particularly easily and unhindered by the stops. The stops can particularly preferably be countersunk flush with the surface of the receiving body, in particular in such a way that neither a depression or opening is created nor a part of the stop remains protruding, so that there is no accumulation of material in front of or in the opening for the stops.

In principle, the at least one displaceable stop can be fixed as desired in the use position and in the retracted position. This can be done, for example, positively and / or non-positively. However, an embodiment of the spool bobbin according to the invention is preferred in which each stop can be locked in the use position and / or in the retracted position, as a result of which the stop can be fixed in a particularly simple manner on the one hand in the respective position, in particular without tools, and on the other hand also particularly easily again can be brought out of this position to adjust the stop or stops.

For this purpose, the stop also preferably has a latching element at an end opposite the receiving region and the receiving body has at least one, preferably two latching element receptacles, by means of which the stop can be fixed in the use position and / or the retracted position. The locking element can be formed in any way. The latching element is preferably formed in one piece with the stop, and particularly preferably the latching element is a nose molded onto the stop. Farther preferably the latching element and particularly preferably the end of the stop with the latching element is prestressed towards the latching element receptacles, the prestressed area of the stop also being particularly preferably formed in one piece with the latching element and / or the remaining part of the stop. The latching element receptacles corresponding to the latching elements can likewise be formed as desired, the latching element receptacles preferably being formed as recesses and / or in one piece with a part of the receiving body. Both latching element receptacles are also preferably arranged one above the other in the receiving body.

In a likewise preferred embodiment of the spool bobbin according to the invention, the stop completely penetrates the part of the receiving body surrounding the stop, so that the latching element of the stop in the retracted position latches with a lower edge of the receiving body or the underside of the receiving body forms the latching element receptacle in this area, whereby an even more simpler construction is possible. In the case of such a receiving body which is open towards the retracted position in the region of the stop, however, it is preferred that the stop, in particular in a form-fitting manner, prevents it from moving beyond the retracted position, i.e. towards the inside of the receiving body.

According to an advantageous development of the coil carrier according to the invention, the at least one stop is arranged in a guide which is displaceable radially to the carrier axis, the guide preferably comprising at least one guide groove arranged in the receiving body and a corresponding guide web of the stop, as a result of which a secure adjustment is achieved in a simple manner. The stop preferably has a constant cross-sectional area in the direction of displacement at least in the section that can be arranged within a part of the receiving body, and the cross-sectional area of the opening of the receiving body for the stop is essentially adapted to the shape or cross-sectional area of the stop.

In a preferred embodiment of the spool bobbin according to the invention, a motorized individual drive of the spool bobbin is provided, by means of which the receptacle body can be rotated with the at least one stop around or by means of the carrier axis, whereby individual control of the spool bobbin carrier is possible in a particularly simple manner and the rotational speed of the Receiving body can be adapted to the spool arranged thereon and its length and diameter.

Likewise preferred is a design of the spool bobbin according to the invention in which the receiving body has a plurality of clamping bodies which are distributed uniformly around the circumference and arranged on a base body, the clamping bodies being movable in the radial direction in order to be able to hold a spinning bobbin in a force-fitting manner, and preferably the at least one stop , in particular all the stops, is arranged on a clamping body. The stops are particularly preferably arranged directly on the clamping body.

Alternatively, the at least one stop, preferably a part of a plurality of stops and particularly preferably all stops, can also be arranged on the base body and in particular between two clamping elements. The at least one stop, particularly preferably all stops, is then preferably arranged in such a way that the stop in the use position in every possible position of the clamping bodies in the receiving area projects beyond the surface of the clamping bodies, so that a spinning bobbin always with the stop regardless of the adjustment position of the clamping bodies and in particular its stop surface can be brought into contact.

Finally, a preferred embodiment of the spool bobbin according to the invention provides that all the stops have a different color and are particularly preferably made of a different colored material, in particular plastic, in order to achieve a better distinguishability of the stops and increased security against incorrect operation.

An advantageous development of the method for using a spool bobbin provides that the stop to be brought into the use position is selected from a plurality of stops such that the length of the receiving region shortened by the stop corresponds to the length of the spinning bobbin to be arranged on the receiving body. Additionally or alternatively, the stop to be brought into the use position can also be selected such that the center of the shortened spinning bobbin is arranged in the center of the unabridged receiving area.

An embodiment of the spool bobbin according to the invention is explained in more detail below with reference to the drawings. The figures show:

• 1 a spinning bobbin according to the invention,
• 1a 1 shows a perspective view of a section of a spinning bobbin carrier with five stops in a retracted position,
• 1b a perspective view of the in 1a illustrated section of the spool bobbin with one of the five stops in a use position, and
• 2nd a side section through the spool bobbin in the area of the stops.

At one in 1 illustrated spool bobbin 1 for a high-performance ring twisting machine, which in 1a is shown in sections, is a receiving body 2nd arranged rotatably about a carrier axis, in order thereby from one in a receiving area 3rd of the receiving body 2nd arranged spool to be able to feed a thread from the spool to the high-performance ring twisting machine. The spider bobbin 1 has an electromotive drive unit that the receiving body 2nd can rotate over the carrier axis.

The receiving body 2nd has a base body comprising the support axis 12 as well as several to the outer periphery of the receiving body 2nd evenly distributed sprags 13 on, with the sprags 13 in relation to the carrier axis radially from the base body 12 are movable to one in the recording area 3rd on the receiving body 2nd to be able to positively set the slid spinning spool. Each of the sprags 13 has a fixed end stop at one end 5 on the the end of the recording area 3rd in the direction in which a spinning bobbin is on the take-up body 2nd is postponed, limited. The length of the capture area 3rd corresponds to the length of a standardized spinning bobbin and the fixed end stops 5 have the function of a defined and repeatable arrangement of a spinning bobbin on the spool bobbin 1 to enable.

In order to be able to also fix spinning bobbins, which are shorter than a standardized spinning bobbin, safely and in a defined location, there are on the receiving body 2nd , especially on a clamp body 13 , several other attacks 4th arranged. The individual attacks 4th are at a constant distance from each other and extend on the surface of the clamping body 13 in an axial direction or coaxial to the carrier axis and along the length of the receiving area 3rd .

If a standardized, long spinning bobbin is used, all further stops are located 4th in a retracted position (see 1a) , in which the further attacks 4th flush with the surface of the receptacle 2nd are sunk so that the spinning bobbin is above the stops 4th or this is outstanding in the entire recording area 3rd can be arranged. The other attacks 4th are, however, slidably arranged independently of each other and can each be in a use position from the surface 7 of the receiving body 2nd be pulled out (see 1b) , so that in the push-on direction of the spinning bobbin onto the take-up body 2nd or in the recording area 3rd first stop in the use position 4th forms the new end stop, since the spinning bobbin does not go all the way to the fixed end stop 5 can be moved. Each stop points to this 4th a flat stop surface 6 on.

To the respective stop 4th To be able to set in the retracted position and in the use position, each stop 4th on the lower one, always inside the receiving body 2nd located end 8th a nose as a locking element 8th on, which is biased such that this in the retracted position and in the use position with a locking element receptacle 10a , b on the receiving body 2nd engaged (see 2nd ). Here is the locking element receptacle 10a for the use position as a recess in the receiving body 2nd , especially in the sprag 13 , educated. As a locking element holder 10b the underside of the receiving body serves for the retracted position 2nd in the area of the attack 4th .

Every stop 4th is in an opening of the receiving body 2nd , in particular the sprag 13 , arranged, which has a cross section corresponding to the cross section of the stop, so that the stop 4th is guided continuously through the opening during the displacement from the retracted position into the use position and back, the stop being improved to improve the guidance 4th a boardwalk 11 having.

To prevent the attack 4th beyond the retracted position further into the receiving body 2nd inside and under the surface 7 of the receiving body 2nd can be pushed, each stop points 4th an upper end surface 14 on that is larger than the cross-sectional area of the rest of the stop 4th so that it matches the surface 7 or a corresponding depression in the surface 7 of the sprag 13 comes into contact and prevents further movement.
