Description

[0001] The invention relates to a spindle head and core transport system for a winding machine having several work stations, with a feed section for supplying spinning heads arranged on transport means to the work stations, a return section for transporting the unwound spinning heads from the work stations, several cross-conveyor sections, each assigned to a work station, connecting the feed section and the return section in the area of ​​the work stations with inlet sections adjacent to the feed section, and several independently driven conveyors, each assigned to a work station, for adjusting the transport means between the feed section and the return section. wherein the feed section extends along the cross-transport sections in such a way that the transport means conveyed in the transport direction along the feed section automatically enter transport-free inlet sections.

[0002] Modern winding machines typically have numerous identical workstations where yarn produced, for example, on ring spinning machines, is rewound onto large-volume cross-wound bobbins. To ensure continuous operation of these workstations, a constant supply of spinning heads is necessary. This is achieved using spinning head and bobbin transport systems of the type mentioned earlier, which transport the spinning heads to the workstations and remove the empty spinning heads.

[0003] Such transport systems include, for example, a conveyor belt guided along a track, on which transport elements designed as transport plates with vertically arranged receiving mandrels for holding spinning heads rotate. The spinning heads remain on these receiving mandrels both during feeding and during unwinding and subsequent removal of the unwound spinning heads, i.e., the empty spools.

[0004] The transport system includes, among other things, a feed track and a return track, as well as several cross-transport tracks extending between the feed track and the return track, which are assigned to the individual work stations and within which the spinning heads are arranged in the unwinding position.

[0005] The feed line extends along the entire length of the winding machine and supplies the individual workstations with spinning heads to be unwound. The transverse transport lines ensure the feeding of the spinning heads to the workstations in the unwinding position and enable the return of the unwound spinning heads via the return line, which extends along the workstations of the entire winding machine, analogous to the feed line.

[0006] The feed section extends along the transverse transport sections in such a way that transport vehicles conveyed along the feed section in the direction of transport automatically enter transport vehicle-free entry sections of the individual transverse transport sections. If transport vehicles are already positioned in the entry sections, subsequent transport vehicles are thus moved further along the transport section at these work points. A transport vehicle positioned in the entry section then serves as a guide element for the subsequent transport vehicle and facilitates its onward transport in the direction of transport along the feed section. The transport vehicles therefore always enter the first free entry section of the work points arranged consecutively in the direction of transport.Within the work areas, the transporter serves to adjust the transport means along the transverse transport route, in particular to position the spinning head arranged on the transport means in the unwinding position.

[0007] This design of the spindle head and core transport system does not allow for the selective assignment of individual spindle heads to specific workstations. The forced processing of the spindle heads introduced into the free infeed sections at the individual workstations, as a consequence of the prior art, therefore does not permit, for example, the processing of single-type spindle heads at one or more workstations. Furthermore, the processing of specific spindle head types at designated workstations cannot be carried out using the known spindle head and core transport systems.

[0008] EP4015429A1, prior art according to Article 54(3) EPC, discloses a bobbin changing device for a winding machine, comprising a first bobbin feed path with a spool onto which yarn is wound, the first feed path being shaped to feed a plurality of bobbins to be unwound, and an input disk arranged to interrupt the first feed path and rotatable about a first axis of rotation. The bobbin changing device according to D1 further comprises an output disk rotatable about a second axis of rotation.

[0009] EP2141104A1 discloses a spindle and core transport system for a cross-coil producing textile machine with a plurality of winding stations, wherein the transport system comprises a feed section for spindles arranged on transport plates, a return section for unwound cores, and transverse transport sections arranged between these sections in the area of ​​the winding stations with a predetermined number of waiting positions for spindles arranged on transport plates. The spindles are blocked along the feed section in such a way that additional waiting positions are created on the feed section, which are occupied when the waiting positions on the transverse transport sections are occupied.

[0010] Based on this, the invention aims to provide a spinning head and core transport system that enables the active assignment of individual spinning heads to individual work stations along the winding machine.

[0011] The invention solves the problem by means of a spindle head and sleeve transport system with the features of claim 1. Advantageous further developments of the invention are specified in the dependent claims.

[0012] A characteristic feature of the Spinnkops and sleeve transport system according to the invention is that the conveyor provided for adjusting the transport means between the feed section and the return section is designed in such a way that in a first rest position it releases the inlet section of the transverse transport section relative to the feed section and in a second rest position it blocks the inlet section relative to the feed section in such a way that the transport means are forwarded in the transport direction.

[0013] The basic function of the conveyor is to reposition the transport elements with their attached spinning heads in the area between the feed and return sections. That is, the conveyor moves a transport element located in an infeed section of the transverse transport section into the unwinding position and, after the unwinding process, transfers it from the unwinding position to the return section. According to the invention, the conveyor can be arranged in two rest positions and is designed such that, in the first rest position, it releases an infeed section of the transverse section adjacent to the feed section. This means that a transport element moving along the feed section in the transport direction then automatically enters the released infeed section, from where the conveyor can reposition the transport element within the transverse section.Furthermore, the conveyor is designed in such a way that, in the second rest position, it blocks off the inlet section opposite the feed section, so that, as a result, the inlet section of this cross section is passed by the transport means moving in the transport direction on the feed section, with the conveyor thereby directing the transport means in the transport direction in the second rest position.

[0014] The inventive design of the spinning head and core transport system enables the selective choice of spinning heads to be processed at the individual workstations. The transporter, which can be arranged in the second rest position, allows the transport element to be routed at each workstation even if the infeed section is not occupied by a transport element. This makes it possible to use specific workstations exclusively for processing certain spinning heads, thus enabling the processing of different spinning heads at designated workstations of a winding machine.

[0015] The positioning of the conveyor in its first or second rest position, and thus the selection of the transport units to be picked up with the spinning heads arranged on them, can in principle be carried out in any way. For example, in the case of a regular supply of different spinning heads, the individual conveyors can be positioned accordingly at the individual workstations via a central control unit, thereby ensuring that they are selectively supplied to the individual workstations.

[0016] According to the invention, a first spindle head identification unit connected to a control unit of the conveyor is arranged at each of the work locations for positioning the conveyor in the first or second rest position.

[0017] According to this further development of the invention, the spinning heads approaching the individual work stations were identified via the first spinning head identification unit. If the first spinning head identification unit recognizes that a spinning head approaching along the transport path is not intended for processing at the work station, then the control unit controlling one of the drive units of the conveyor causes the conveyor to be positioned in the second rest position, so that this spinning head passes the corresponding work station and is transported further along the transport path.

[0018] If, however, the first spindle identification unit detects a spindle to be processed at the corresponding workstation, the control unit positions the conveyor in its first rest position, so that the spindle enters the infeed section of the cross-section, from where it can then be moved via the conveyor to the unwinding position. This embodiment of the invention allows for a particularly reliable identification of the spindles assigned to the respective workstations and their corresponding introduction into the workstation.

[0019] According to a particularly advantageous embodiment of the invention, the first spinning head identification units and the conveyors are connected to a central control unit for adjusting the conveyors. In this embodiment, the positioning of the conveyors in the first or second rest position, as well as their subsequent control for moving the spinning head or the transport elements within the transverse path, is carried out via a central control unit of the winding machine. This control unit is designed to control the drives of the individual conveyors depending on the identification data supplied by the first spinning head identification units. The central control unit, the spinning head identification units, and the drive units of the conveyors are interconnected via suitable data lines.The use of a central control unit allows for a particularly reliable selective assignment of the individual spinning heads to the individual work locations.

[0020] The arrangement of the first spindle identification unit at each workstation can, in principle, be arbitrary. However, according to a particularly advantageous embodiment of the invention, it is provided that this unit is arranged in the inlet section, so that the spindles approaching the respective workstations can be detected in a particularly reliable manner, and thus the spindles intended for processing can be identified.

[0021] According to a further embodiment of the invention, a second spindle identification unit is provided, which is arranged in the area of ​​an unwinding position of the workstations. The use of a second spindle identification unit makes it possible to verify the spindles supplied to the workstation, thus ensuring with particular reliability that only those spindles intended for processing at the workstation are processed there. Error detection by the first spindle identification unit can therefore be corrected by the second spindle identification unit, thereby achieving high reliability in the detection of the spindles to be processed.

[0022] Should the second spindle identification unit identify a spindle that is not to be processed, it is possible to transfer this spindle from the transverse transport section back to the feed section using the conveyor. According to a particularly advantageous embodiment of the invention, the control unit and / or the control device is designed to adjust the conveyor both in the direction of the return section and in the direction of the feed section. By adjusting the conveyor in the opposite direction to the return section, it is thus possible to return the spindle that was incorrectly directed to the work area to the feed section, from where it then reaches the work area intended for processing.

[0023] The design of the Spinnkops identification units is generally freely selectable. They preferably feature an RFID reading unit, which enables particularly reliable identification.

[0024] The design of the conveyor is generally freely selectable. However, a particularly advantageous embodiment provides that the conveyor has a transport wheel with at least one, preferably at least three, and particularly preferably six carriers. These carriers have transport pockets open towards the return path in the area of ​​the transverse transport section for receiving the transport elements, in particular guide bases of transport elements designed as transport plates. Designing the conveyor as a transport wheel allows for a particularly simple and compact design, whereby the rotation of the transport wheel, in conjunction with the interaction of the transport pockets with the transport elements, reliably adjusts the transport elements along the transverse transport path. The shape of the transport pockets is adapted to the design of the transport elements and their contact area with the transport pockets.For example, the transport bags can have openings that are adapted to the shape of the guide bases of the transport plates, so that reliable adjustment of the transport means within the transverse distance and, in particular, positioning in the unwinding position is ensured.

[0025] The design of the conveyor such that, in a first rest position, it releases the inlet section relative to the feed path and, in a second rest position, blocks the inlet section relative to the feed path, is generally freely selectable. In the advantageous configuration of the conveyor as a transport wheel, a further development of the invention provides that the drivers on the rear sides opposite the transport pockets have a guide surface that, in the second rest position, limits the feed path in the area of ​​the inlet sections.The backs of the transport bags are therefore not arbitrarily designed, but shaped in such a way that in the second rest position they block off the inlet section and at the same time form a guide surface on which the transport means passing the work site slide and are thus reliably guided past the work site along the transport direction.

[0026] According to a further embodiment of the invention, the transport wheel is designed and / or positioned at the work site such that it is disengaged from a transport means arranged in the unwinding position. This embodiment of the invention ensures that, even if the transport means is moved back into the unwinding position, the spinning head in the unwinding position will not be displaced. Thus, after the spinning head is in the unwinding position, it is possible to accept additional spinning heads and store them as spares at the work site, or to return incorrectly inserted spinning heads to the feed section without changing the position of the spinning head in the unwinding position.

[0027] According to a further embodiment of the invention, an outlet section extending between the unwinding position and the return section is designed such that a transport element arranged in the unwinding position is transferred into the feed section by means of a transport element moved into the unwinding position. This embodiment of the invention ensures in a particularly reliable manner that a transport element with an emptied spinning head is reliably transferred via the conveyor, through the outlet section, and into the return section by means of a subsequent transport element.

[0028] An exemplary embodiment is explained below with reference to the drawings. The drawings show: Fig. 1 a perspective view of a section of a spinning head and sleeve transport system and Fig. 2 a perspective view of a section of the spinning head and sleeve transport system of Figure 1with spinning heads arranged on means of transport.

[0029] In Figure 1 A perspective view shows a section of a spinning head and core transport system 1 of a winding machine (not shown here). The spinning head and core transport system 1 has several workstations 5 assigned to the individual winding stations of the winding machine, at which the spinning head 11 is unwound in an unwinding position 12 and the thread is wound onto a cross-shaped bobbin of the winding station (not shown here).

[0030] To supply the individual workstations 5, the spindle and core transport system 1 has a feed section 3. Along the feed section 3, the spindles 11 are guided past the individual workstations 5 on the transport means 9. The workstations 5 are each bordered by a transverse transport section 6 on the feed section 3 in such a way that transport means 9 moving in the transport direction T on the feed section 3 enter the transverse transport section 6 via a free inlet section 7 of the transverse transport section 6, within which the transport means 9 are repositioned by means of a conveyor designed as a transport wheel 8, in particular transported into the unwinding position 12.

[0031] To reposition the transport means 9 arranged in the transverse transport sections 6, the conveyor, designed as a transport wheel 8, has several carriers 13 by means of which the transport means 9 with their spinning heads 11 arranged on them are moved along the transverse transport section 6. For repositioning the transport means 9, the carriers 13 have transport pockets 14 which have a shape adapted to a guide base 15. The guide base 15 is part of a transport means 9 designed as a transport plate 16 and also serves for the rotatable mounting of the spinning heads 11 on the transport means 9.

[0032] The transport wheel 8 can be arranged in a first and a second rest position. Figure 1The transport wheels 8 are arranged in a second rest position, in which they close the inlet section 7 of the individual transverse transport sections 6, wherein a guide surface 18 arranged on a rear side 17 of the carriers 13 limits the feed section 3 in such a way in the area of ​​the inlet sections 7 that transport means 9 moving in the transport direction T slide off the guide surfaces 18 and are guided past the individual work stations 5, in which the transport wheel 8 is in the second rest position.

[0033] In a first rest position not shown here, the drivers 13 are arranged such that the inlet section 7 is released relative to the feed section 3, so that transport means 9 moving in the transport direction T enter the released inlet sections 7, from where they are then transported by a rotation of the transport wheel 8 to the unwinding position 12.

[0034] The position of the transport wheel 8 in its first or second rest position is determined by individual drives of the individual transport wheels 8, each of which is connected to a central control unit (not shown). The positioning of the transport wheels 8 is achieved via the signal inputs of spindle head identification units (also not shown) connected to the control unit, which detect the spindle head 11 approaching the respective work station 5. Depending on the identification, the control unit then activates the individual drives to position the transport wheel 8 in its first or second rest position.

[0035] If a spinning head 11 intended for processing is identified, the transport wheel 8 is moved into the first rest position, allowing the spinning head 11 to enter the infeed section 7. If, however, the approaching spinning head 11 is not intended for processing at the work station 5, the transport wheel 8 is moved into the second rest position, allowing the spinning head 11 to pass through the work station 5.

[0036] After the unwinding process of the spinning head 11 in the unwinding position 12 is completed, a subsequent transport means 9 with a spinning head 11 is moved by a rotation via the transport wheel 8 in the direction of the transport means 9 which is in the unwinding position 12, whereby in the interaction of the subsequently conveyed transport means 9 the transport means 9 which is in the unwinding position is conveyed via a discharge section 10 onto the return track 4, via which the emptied spinning head 11 is then discharged from the winding machine.
