Definitions

  • the invention relates to a device for feeding threads, in particular elastomer threads.
  • the devices are provided on the knitting or knitting machines as separate units and fastened with appropriate clamps to a section of the machine frame provided for this purpose.
  • these devices are supplied as a supplier part and mounted on it. This should be done in the simplest and fastest possible way.
  • a device for feeding elastomeric threads for knitting or warp knitting machines which has a housing to be fastened to a machine frame and enclosing an interior.
  • the housing is penetrated by two drive rollers, which are each arranged horizontally and at a distance parallel to one another. Each drive roller protrudes from the housing at both ends.
  • Rolling bearings for rotatably supporting the drive rollers are provided in the housing.
  • a toothed belt pulley with a vertically oriented axis is used to drive the drive rollers. This works via a bevel gear drive provided in the interior of the housing and a toothed belt on the two drive rollers.
  • the aforementioned toothed belt pulley arranged outside the housing serves to drive the entire device and is connected to a toothed belt which drives the toothed belt pulleys of several devices arranged on the knitting or knitting machine.
  • the housing has lateral flat surfaces with openings through which the drive rollers pass. When installing the device, the drive rollers must be pushed through these openings.
  • a device for feeding elastic yarn threads in which two drive rollers arranged parallel to one another at a distance are each mounted in a solidly shaped holding body via pairs of ball bearings.
  • the thickness of the solid body corresponds approximately to the thickness of two ball bearings lying directly next to each other.
  • Each drive roller is formed in one piece with a toothed belt pulley, which is arranged laterally next to the solid holder.
  • a toothed belt runs over the toothed belt pulleys of both drive rollers and thus serves to drive them.
  • a thread supply device for feeding elastomeric thread which has a two-part housing.
  • the thread feed device two drive rollers protruding from the housing at both ends are provided, which are rotatably mounted in the housing at a distance parallel to one another.
  • each drive roller is provided with a bearing device, a bearing plate and a toothed belt pulley arranged in the immediate vicinity.
  • the housing is divided along a plane on which the drive rollers are perpendicular.
  • One of the two housing parts has two cylindrical receiving pockets which are open on one side and can accommodate the bearing devices seated on the drive rollers.
  • the receiving pockets are provided with three threaded holes on each side for fastening the end shields.
  • a toothed belt for synchronously driving the two drive rollers runs alongside the bearing means over the pulleys.
  • the toothed belt is covered by the other part of the housing, which contains no other bearing means.
  • the receiving pockets for receiving the bearing devices are formed in one piece and must be manufactured accordingly precisely.
  • Thread supply devices are required in large numbers for knitting and warp knitting machines. It is therefore desirable to have the thread supply devices available in the required quality at the cheapest possible price. In addition, it is desirable that the thread supply devices can be assembled and disassembled in the simplest possible way.
  • the device for feeding threads has two bearing rollers, at least one of which is driven.
  • the bearing rollers are arranged at such a distance from one another that the smallest distance between their peripheral surfaces is smaller than the outer diameter of the bobbin tube of the take-off bobbin.
  • the bobbin from which the elastomeric thread is to be pulled, lies on the bearing rollers running in the same direction.
  • the housing By separating the housing into two housing parts along a parting line which runs through the recesses, the housing is divided into at least one upper part and one lower part in the installed position.
  • the bearing rollers can be inserted into the recesses directly from the parting line or provided with bearing means, each of which has an opening accessible from the parting line.
  • the lower housing part in the position of use is designed in such a way that it is possible to insert the bearing rollers with bearing means and with the gear means into the lower housing part with the housing open. This enables assembly, ie assembly of the device by inserting the relevant parts into the lower housing part from the parting line.
  • the lower housing part serves as an assembly aid during assembly. No auxiliary devices for pressing any parts into corresponding receptacles or the like are required.
  • a double-shell design of the housing when separated along a separating joint passing through the openings mentioned also makes it possible to create particularly simple and tolerance-insensitive bearing seats for the bearing means.
  • Corresponding bearing seats are molded in both housing parts.
  • a bearing seat is bounded in part by one housing part and in another part by the other housing part. This makes it possible to clamp the corresponding bearing means between the upper and lower housing parts without the necessary bearing seats having to be manufactured with excessive accuracy. This creates the possibility of manufacturing with tolerances that are not too narrow, which is more cost-effective than manufacturing with very small tolerances. This enables cost advantages.
  • the recess or the bearing seat can be formed by a trough-like recess which has an opening passing through the parting line.
  • the opening of the recess lies in a surface forming the parting line, from which the recess extends into the housing wall.
  • the housing parts are essentially free of undercuts and can be cheaply produced as simple injection molded parts.
  • a simple housing shape is obtained if the parting line lies at least in sections in a plane which is aligned both parallel to the axis of rotation of the first drive roller and parallel to the axis of rotation of the second drive roller.
  • This section lies with the bearing rollers, which enables a clear design of the housing parts, especially in this area.
  • the bearing means accommodated by the housing parts can be protected against contamination by sealing means acting outwards.
  • sealing devices prevent abrasion, dust or lubricant from escaping from the housing and causing contamination, and also prevent dust and contaminants from entering the housing from the outside.
  • the housing can be produced in a simple manner from plastic, in particular as an injection molded part.
  • the accuracy of injection molded housing parts is sufficient for the intended use, so that these parts can be used without reworking thanks to the arrangement of the parting line in the area of the bearing means.
  • the holding devices for holding the bearing means are preferably recesses provided in the housing parts, in which the bearing means are clamped when the housing is closed.
  • the recesses are preferably designed as receiving pockets. These have side walls that fix the bearing means in both axial directions. However, the receiving pockets are accessible from the parting line, so that the bearing means can be simply inserted into the receiving pockets when the device is being assembled.
  • the recesses in the housing parts are preferably designed differently. While the recesses in one half of the housing accommodate the bearing means without play and thus determine their position, the recesses in the other half of the housing can be designed such that the Storage means have some play in the direction of the parting line. However, the depth of the recess or receiving pocket in question is dimensioned such that the bearing means finds its abutment in the recess. It is thereby achieved that the bearing means is firmly seated in the holding device for the bearing means formed by mutually opposite recesses. In addition, however, the connection of the housing parts with a certain tolerance is possible. In any case, they do not have to be positioned exactly in relation to one another, so that dowel pins or other comparable adjustment means can be dispensed with.
  • the mounting of the storage means is particularly insensitive to production tolerances and is secure with regard to the mounting of the storage means if the holding devices are provided with spring means. These keep the bearing means on the housing without play.
  • the spring means can be formed in one piece with the housing part of the same.
  • An embodiment in which the assembly, i.e. the assembly of the device can be carried out particularly easily, has a housing which is designed such that the bearing rollers and the gear means are completely fixed in relation to one another by means of a single housing part. This makes it possible to insert and thus assemble all parts in one housing part during assembly, the device being fully assembled by fitting the second housing part.
  • the device can be designed in this way; that the bearing rollers only protrude from the housing on one side. However, more spools of thread can be picked up and unwound at the same time if the bearing rollers protrude from the housing on both sides.
  • the bearing roller can be formed in one piece or composed of several parts.
  • the bearing roller has a center piece, onto which roller parts are attached on both sides and secured by means of clamping screws.
  • good concentricity of the bearing rollers is easily achieved. This is important for the uniformity of the thread supply.
  • the gear means engages between two bearings that support the bearing roller. This results in a uniform load on the bearings, which enables the device to work precisely.
  • the gear means is preferably a combined gear belt drive.
  • a bevel gear is provided between a drive shaft, which protrudes from the housing at one end and carries a pulley at this end, and a primary shaft rotatably mounted in the housing.
  • This has a bevel gear which is fixedly connected to the drive shaft and which meshes with one of two bevel gears slidably arranged on the primary shaft and fixed by means of clamping screws.
  • the direction of rotation of the primary shaft is possible by selecting the gear meshing with the bevel gear of the drive shaft.
  • a belt serves as the force transmission means between the primary shaft and the first bearing roller lying first of the primary shaft.
  • a round belt, a toothed belt, a flat belt or the like can be used as the belt.
  • tensioning means for maintaining the belt tension are unnecessary.
  • a toothed belt that works without slippage is advantageous, so that the first bearing roller has a defined speed.
  • a second toothed belt can be used as a force transmission means between the first bearing roller and the second bearing roller run. Compared to an embodiment with only one toothed belt running over the primary shaft, the first and the second bearing roller, this has the advantage that larger wrap angles are achieved, so that even with a lower belt tension there is no fear of the bearing rollers skipping and thus not synchronous running.
  • metal or plastic chains can be used for the drive.
  • connection of the housing parts to one another can be brought about, for example, by simple positive locking means. These are screw connections or snap connections. Snap-in connections have the advantage that assembly is particularly simple with a suitable design and that the snap-in means can be formed in one piece with the housing parts.
  • the latching means can be latching tongues or other latching projections provided on a housing part, which engage in corresponding recesses in the respective other housing part.
  • the housing parts can also be cohesive, i.e. can be connected to each other by gluing or welding, resulting in robust housing designs.
  • Sensor means such as switches or the like can be provided on the thread supply device for monitoring the bobbins or the thread path.
  • These sensor means are carried, for example, by a rail provided on the housing, which is provided with holding means for the coils to be unwound.
  • the sensor means are connected via electrical lines to an electrical connection device which is arranged in a fastening device provided for fastening the housing to the machine frame.
  • the electrical lines are formed by metal strips inserted into the housing, for example by molded or otherwise molded Holding knobs are fixed in the housing. The metal strips extend over the parting line, with corresponding resilient contact means being provided in the parting line, which bring about an electrical contact when the housing parts are placed on one another.
  • an adjustable device for axially fixing the coils on the bearing and drive rollers is provided.
  • This is preferably the above-mentioned rail attached to a housing part, on which an optionally lockable rider sits with a sling.
  • the rider is fixed by means of a clamping screw which can also be adjusted while the thread feeding device is in operation.
  • the supply device 1 shows a delivery device 1 for elastomeric yarns, but without a yarn spool to be unwound.
  • the supply device 1 is provided for a knitting or knitting machine to which a plurality of similar supply devices 1 are attached.
  • the supply devices 1 then each take up one or more spools of thread and unwind them at a predetermined speed, so that the elastomeric yarn is fed to the knitting points with constant thread tension.
  • the supply device 1 has a L-shaped housing in plan view with rounded edges, the cross section of which is approximately square with rounded corners.
  • an extension 5 is formed on its shorter leg with a clamp 6 for attachment to a machine frame, not shown.
  • the housing 3 is divided into two at a parting line 8 and has a lower housing part 10 and an upper housing part 11, which are each formed as one-piece plastic injection-molded parts.
  • the parting line 8 lies in a plane which cuts the housing 3 approximately in the middle.
  • at least one housing part 10 can be provided with a sealing means, for example a lip molded in one piece.
  • Two bearing rollers 13, 14; 13 ', 14' which serve to receive and drive the yarn packages to be unwound (FIG. 3).
  • Such a yarn spool is with its peripheral surface on the horizontal in the use position and rotating about an axis of rotation 12, 12 'bearing rollers 13, 14; 13 ', 14' placed such that when the bearing rollers 13, 14; 13 ', 14' rotates about its own coil axis.
  • the distance between the bearing rollers 13, 14 is smaller than the outer diameter of a bobbin carrying the coil. The same applies to the bearing rollers 13 ', 14'.
  • a rail 15 is arranged in the position of use below the housing 3, which is supported by the housing part 10 by means of a holder 17 and which, as can be seen, for example, from FIG. 3, serves to to carry a coil limiter 19.
  • This coil limiter 19 has a slide which can be displaced on the rail 15 and can be locked by means of a clamping screw, for example a knurled screw 20, from which a limiting rod 22 projects approximately at right angles to the rail 15 so far that one lying on the bearing rollers 13, 14 Coil is held in its axial direction. A corresponding tab sits on the section below the bearing rollers 13 ', 14'.
  • the coil limiter 19 enables simple adaptation to different coil widths and numbers.
  • the bearing rollers 13, 14; 13 ', 14' lead through an interior space 23 which is delimited by the housing and can be seen, for example, from FIG. 2 and in which gear means for driving the bearing rollers 13, 14 are arranged.

  • the transmission means 25 used to transmit power from the drive wheel 27 to the bearing rollers 13, 14 and the bearing of the bearing rollers 13, 14; 13 '14' on the housing 3 are shown in Fig. 2.
  • a primary shaft 29 is rotatably mounted in the shorter leg of the interior 23, which is L-shaped like the housing 3, and a Bevel gear 31 carries. As is also apparent from FIG. 4, this is in meshing engagement with a bevel gear 32, which in turn is seated in a rotationally fixed manner on the shaft driven by the drive gear 27.
