Definitions

  • the invention relates to a train according to the preamble of claim 1.
  • Tractors of the generic type are used in fiber lines between individual processing stations application. By driven rollers around which the filaments bundled into cables are guided, the necessary to promote the filaments tensile forces are applied.
  • the invention is therefore based on a train for the transport of filaments, in particular carbon filaments, consisting of a number of driven rollers around which the filaments are guided, wherein one of the rollers cooperates with an employee counter-roller and the filaments run through the nip formed in this way.
  • the filaments are endless fibers. A strand or a bundle of filaments forms a cable.
  • Object of the present invention is to improve a generic device.
  • rollers and their drive are accommodated in a transportable frame unit.
  • the train may be equipped with a different number of driven rollers.
  • the entry and exit serving rollers are not driven.
  • the driven rollers are driven according to a preferred embodiment of the invention by a drive via a traction means (chain).
  • the drive further includes the electrical control and the power supply, so that the train of the invention after the mechanical installation only needs to be connected to the network and connected to the control of the fiber line.
  • the preferably mounted on top of the frame drive does not hinder accessibility to the individual rollers of the train.
  • the driven rollers can each be assigned a single motor, so that the rollers can be driven separately from each other. Also, in this case, the individual motors can be controlled separately. The motors can be controlled, for example, by controlling the torques of the respective motors.
  • the non-driven rollers of the inlet and / or outlet are preferably arranged in height adjustable on the frame, so that the height of the cable run can be adjusted. This is particularly advantageous when the train according to the invention is upstream or downstream of a furnace and the filaments combined into cables are in particular carbon filaments. Such devices usually have very narrow input gaps for the cables to be treated, by the adjustability of the cable run can be made to adapt to the particular circumstances.
  • a further embodiment of the invention provides that the non-driven input and / or output roller is coupled to a measuring system for detecting the tension present in the incoming or outgoing cable. This is done for example by a load cell, which is mounted between the frame and the storage of the respective roller.
  • a measuring system designed in this way allows the force exerted by the cable on the roller to be taken into account
  • Running directions are determined in the cable traction. These values are used to monitor the operation and in particular to avoid too high voltages during the startup of the system, since here the system parts connected in series are to be operated in a coordinated manner with respect to each other in their speed. This has the advantage that filmmentrisse be avoided.
  • At least one of the driven pull rolls is at least partially connected, that is to say provided with a cover surrounding the roll surface at least in a partial circumferential region.
  • a draw roller is a roller of the train.
  • the cup-shaped covers serve to protect people and prevent hazards due to incoming column, especially in the area between the running on a draw roller cable and the corresponding rotating roller surface.
  • the cover is preferably associated in the partial circumference of the roller surface of the tension roller, around which the filaments bundled in cables are not wound in normal operation.
  • normal operation means that there is no Filamentriss.
  • the torn off filaments wrap around the roll (s) and, in this case, also the partial circumference of the roll surface of the roll is wrapped with the cables in which the cover is arranged.
  • a further embodiment of the invention provides a remedy, which provides a running in the axial direction of the respective roller and parallel to this guide for a cutting device.
  • the leadership is designed so that the Cutting device by means of the guide to the roll surface of the roll guide and / or preferably in the axial direction along the roll surface of the roll is feasible.
  • the cutting device is, for example, a knife attached to an extension, which is pulled by the operator along the guide over the roll surface of the roll.
  • the cutting device is moved manually.
  • the cutting device can also be actuated automatically.
  • a drive for example an electrically driven drive, which has a cutting device, e.g. a knife, moved by means of the guide to the roll surface and / or preferably moved in the axial direction along the roll surface.
  • the electric drive can be actuated for example by an operator as soon as the operator determines that it has come to a winding.
  • this guide if it is formed in the form of a slot in a roll 29alenden the cover.
  • the drive is arranged in an upper part of the frame unit.
  • the drive is coupled via a traction means with the driven tension rollers.
  • the traction means is designed as a chain and the tension rollers are driven by sprockets wrapped around the chain.
  • At least one of the draw rollers is associated with a extending over its length and a partial circumference covering part cover.
  • At least one of the tension rollers is associated with an axially extending guide for a cutting device.
  • the guide is designed such that the cutting device by means of the guide to the roll surface and / or preferably in the axial direction ent ⁇ long the roll surface of the tension roller is feasible.
  • the guide is formed by a running in the axial direction of the draw roller gap of the partial cover.
  • the train has at least one of the inlet and / or outlet of the cable ⁇ nende, non-driven inlet and / or outlet roller.
  • the inlet and / or outlet roller is mounted in height adjustable on the frame unit.
  • the inlet and / or outlet roller is mounted on the frame unit via a force measuring system.
  • FIG. 2 shows the course of the cables
  • FIG. 3 shows the drive of the rollers
  • FIG. 4 shows a further embodiment of the train according to the invention
  • FIG. 5 shows a side view of the train of FIG. 4,
  • FIG. 6 shows a partial cover according to the invention of a draw roller
  • FIG. 7 shows a side view of the draw roller with partial cover from FIG. 6.
  • Figure 1 shows a train according to the invention in a perspective view.
  • a common and consisting of four vertical posts together with cross members frame G carries each a non-driven inlet and outlet roller EW, AW and three driven tension rollers ZI, Z2, Z3.
  • the middle of the tension rollers Z2 cooperates with a counter roller GW, which is adjustably mounted at its two ends and is adjustable relative to the tension roller Z2.
  • the adjustment of the counter roll GW to the tension roller Z2 is done by motor or pneumatically by an associated drive GAl, GA2, which engage the bearings of the counter roll GW and thus enables an exact parallel position of the rollers GW, Z2.
  • the filaments F preferably carbon filaments, which are bundled into cables, run into the pulling mechanism via an inlet roller EW.
  • FIG. 2 shows the arrangement of the rollers EW, ZI, Z2, Z3, GE, AW; the conveying direction of the filaments F is indicated by the arrows. This also applies to the other figures.
  • the incoming on the top of the inlet roller EW filaments F are deflected by the inlet roller EW down and run around the first, lying below draw roller ZI. From there, the filaments F bundled into cables run to the above lying draw roller Z2 and through the gap formed with the counter roll GW.
  • the filaments F bundled into cables now run down again to the third drawing roller Z3 and then to the outlet roller AW located at the same height as the inlet roller EW. About this exit roller AW leave the bundled to cables filaments F the train again.
  • the wrapping of the inlet and outlet rollers EW, AW through the filaments F bundled into cables is less than 90 °.
  • the looping of the draw rollers ZI, Z2, Z3 through the bundled filaments F is substantially 180 °. This results in a good transmission of the drive torque of the rollers ZI, Z2, Z3 on the bundled filaments F.
