Definitions
- the invention relates to a yarn joining device according to the preamble of claim 1.
- Thread connecting devices for example for the pneumatic splicing of two thread ends, have long been known, in particular in connection with reciprocating machines, and have been described in detail in numerous patent applications in various embodiments.
- the yarn ends to be joined are prepared before the actual splicing process, that is, at least partially freed from their yarn rotation.
- the preparation of the thread ends for the splicing process can be done either pneumatically via so-called thread end-Auflöserschreibchen or mechanically, for example, by two opposing friction plates.
- Fadensleiißvorraumen in which the preparation of the yarn ends via two oppositely driven friction plates are known for example from DE 30 29 452 C2.
- a splicing prism is also positioned between the friction disks which pneumatically connects the yarn ends mechanically prepared by the friction disks.
- the pneumatically operated splicing prism in the region of its splice channel in addition to the usual splicing holes still additional holes that can be acted upon by negative pressure and serve to fix the thread ends in the splice.
- the preparation of the yarn ends can be carried out either pneumatically by yarn end dissolution tubes or mechanically by two friction disks driven in opposite directions.
- DE 30 29 452 C2 nor EP 1 302 428 A1 contains any information on how the friction disks are fixed in the yarn splicing apparatus.
- EP 0 140 412 B1 describes thread-connecting devices in which the thread ends are acted upon by two friction disks which can be driven in opposite directions so that the yarn ends are twisted together.
- the friction discs of these known thread connecting devices are both rotatable and limited tiltably mounted in receiving elements of the thread connecting device. That is, the friction discs are each supported by a plurality of coil springs on an associated rotary part, which in turn is arranged in each case in a bearing housing of the thread connecting device.
- the relevant thread connecting device Since the friction plates are barely accessible to a change of the friction plates, the relevant thread connecting device must first be removed from the cheese and then partially disassembled.
- the present invention seeks to provide a equipped with friction discs thread connecting device whose friction plates are easily replaceable if necessary.
- the inventive construction of a thread connecting device with friction plates which are easily accessible and tool-less attached to mounting rings of the thread connecting device and removable mounted so that a change of the friction, which are known to be subject to wear, at any time, without the thread connecting device previously removed from the textile machine
- it has the advantage that no special knowledge or special tools are required for installing or removing these wearing parts.
- worn friction plates can be removed by the regular operating staff of the textile machine in the shortest possible time easily removed and replaced at any time by new friction discs.
- the friction discs are thereby frictionally fixed to the receiving rings by permanent magnet inserts (claim 2).
- the permanent magnet inserts correspond with bearing rings of the friction disks, which are made of a ferromagnetic material, such as steel.
- each of the receiving rings has at least one Reibusionnmit choir corresponding to a recess on a bearing ring of the friction plates and at least one fixed in a bore of the receiving ring permanent magnet insert.
- Such trained receiving rings which in turn are rotatably mounted in the Fadensleiißvorraum ensure that the friction discs are fixed in a form-fitting and magnetically secure fixed.
- each of the receiving rings has two diametrically arranged Reibusionnmit counseling and that in each of the receiving rings two likewise diametrically arranged bores for receiving permanent magnet sets are embedded.
- the friction disc which is made of a ferromagnetic material is ensured by such an arrangement that not only a uniform distribution of forces in the torque introduction is achieved during operation, but it is also a uniform fixation the friction discs secured to the receiving ring.
- the friction disc has a bearing ring made of a ferromagnetic material and a preferably made of a plastic friction lining, which is fixed inextricably on Lagering.
- the bearing ring made of a ferromagnetic material, preferably made of steel, allows in a simple manner a secure, if necessary, but easily releasable fixation of the friction discs on the receiving rings, while the plastic material of the friction ensures that the thread ends by the opposing friction discs reliably from their Garnwindung can be exempted.
- the plastic material of the friction linings is formed so that the thread ends are taken when rotating the friction plates and rolled about its longitudinal axis. In this way, the thread ends, depending on the direction of rotation, either de-twisted or provided with a new yarn twist.
- the friction lining in the bearing ring is either fixed by adhesive bonding or secured by vulcanization.

- FIG. 3 is an exploded view of the yarn splicing apparatus of FIG. 2,
- FIG 1 in front view schematically a generally designated by the reference numeral 1 cross-winding textile machine producing, in the embodiment, a cross-winding machine, shown.
- Such automatic packages 1 usually have between their (not shown) Endgestellen a plurality of similar jobs 2 on which, as known and therefore not further explained, spinning cops 9, which were produced for example on a ring spinning machine, are rewound to large-volume cheeses 15.
- these cheeses 15 are transferred by means of an automatically operating service unit, preferably a (not shown) cheese change on a machine-length cheese package conveyor 21 and transported to a machine loading side arranged Spulenverladestation or the like.
- an automatically operating service unit preferably a (not shown) cheese change on a machine-length cheese package conveyor 21 and transported to a machine loading side arranged Spulenverladestation or the like.
- Such automatic packages 1 usually also have a logistics device in the form of a bobbin and tube transport system 3, in which, on transport plates 8 in vertical alignment, spin cops 9, or empty tubes rotate.
- a logistics device in the form of a bobbin and tube transport system 3, in which, on transport plates 8 in vertical alignment, spin cops 9, or empty tubes rotate.
- this coil and sleeve transport system 3 only the Kopszu slaughterhouse 4, the reversibly driven storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the sleeve return path 7 are shown in Figure 1.
- Such automatic packages 1 usually have a (not shown) central control unit, which is connected via a machine bus both with the workstation computers 29 of the individual winding units 2 and with a control device of the service unit.
- the delivered spinning cops 9 are rewound in the Abspul einen AS, which are each located in the region of the transverse transport lines 6 at the winding units 2, to large-volume cheeses 15.
- the individual winding units have for this purpose, as known and therefore only hinted at various facilities that ensure proper operation of these jobs.
- the thread connecting device designed as a pneumatic thread splicing device 10 is preferably set back slightly with respect to the regular yarn path and, as indicated for example in FIG. 3, has a centrally arranged, axially displaceably mounted, pneumatically actuable splicing prism 11 for connecting two yarn ends 31. 32 and friction plates 16, 17 for mechanical processing of the thread ends 31, 32.
- Such job sites 2 usually also have other, not shown, facilities, such as a thread tensioner, a thread cleaner, a waxing device, a thread cutting device, a yarn tension sensor and a lower thread sensor.
- facilities such as a thread tensioner, a thread cleaner, a waxing device, a thread cutting device, a yarn tension sensor and a lower thread sensor.
- winding devices 24 have inter alia a coil frame 28 which is movably mounted about a pivot axis 22 and has means for rotatably supporting a cheese package.
- the cross-wound bobbin 15 which is freely rotatably mounted in the creel 28, rests with its surface on a bobbin drive drum 14 and is taken along by it by way of frictional engagement.
- the thread splicing device 10 according to the invention is in the
- FIG. 2 shows the yarn splicing apparatus 10 in a perspective view from the front
- Fadensverlißvoroplasty 10 in the form of an exploded view shows.
- each receiving ring 19 preferably has two diametrically arranged Reibusionmitcret 23 A, 23 B and two likewise diametrically arranged holes 27.
- holes 27 In the holes 27 while permanent magnet inserts 26 A, 26 B are set, which correspond to the bearing rings 30 of the friction plates 16, 17.
- the bearing rings 30 of the friction discs 16, 17 are made of a ferromagnetic material, preferably made of steel, and have recesses 34A, 34B, which, as shown for example in Figure 5, in the assembled state, the Reiblationnmitivity 23A, 23B of the receiving ring 19 overlap ,
- each set a friction lining 33, which is preferably made of a plastic material.
- the material of the friction linings 33 is preferably chosen so that when the friction discs 16, 17 at the thread ends 31, 32, depending on the direction of rotation of the friction discs 16, 17, the thread ends 31, 32 can either be de-twisted or that new spin on the Yarn ends 31, 32 is applied.
- the friction discs 16, 17 of the thread connecting device 10 of the relevant job 2 may for example be worn or dirty and should therefore be replaced or cleaned.
- the friction discs do not necessarily have one
- Friction lining is set, but the friction disc can also consist directly of one or more plastics, in / a recessed steel insert is inserted.
- a clip connection may be provided.
- clips which are preferably arranged on the receiving rings, overlap the friction disks or their bearing ring positioned in the working position.
- friction discs could also be secured by spring rings on the receiving rings of the thread connecting device.
- the spring washers must in this case only be designed so that they can be adjusted by hand.
- the contour of the bearing ring of the friction discs and the shape of the receiving ring can be matched directly to one another so that they fit into each other and are positively fixed by rotation, for example.
- Essential in the sense of the general inventive concept is merely that the friction discs on receiving rings of the thread connecting device easily accessible and without tools are switched on and interchangeably mounted so that a change of the friction plates even with built-in thread connecting device for staff is possible, which does not have special expertise.
