Definitions

  • the present invention relates to a winding device for film tape cassettes for writing utensils, with an unwinding, a winding and a brake to achieve a constant tension in the tape in the writing zone.
  • Cassettes for coated film tapes have been used in writing instruments of all kinds, e.g. As typewriters, teleprinters, data printers, etc., found widespread use because they allow a clean, quick and easy replacement of the used tapes.
  • the desire to be able to write as many characters as possible with a tape before the cassette had to be replaced was opposed from the beginning to the need to produce cassettes of small dimensions and light weight.
  • Smaller-sized cassettes were developed from the originally relatively large tape cassettes. The more compact the machine is built, the more compact the film tape cassette should be. So far two solutions have been proposed for this purpose.
  • the first solution which has become known from US Pat. No. 4,010,839, provides for the unwind to be held on a stationary axis from which the tape unwinds.
  • the take-up side of the cassette is designed such that the pivot point of the take-up shifts with increasing diameter of the latter, so that the axis moves towards the center of the cassette with the aid of a pivoting lever.
  • the second solution which has become known from US Pat. No. 853,704, proposes that only the reel alone is rotatably supported on a carrier and can be moved together with it.
  • a tape cassette for a pre-winding drive device and a rewinding output device has become known from DE-OS 1 574 439 and the associated parallel application US Pat Cassette body are arranged, which is provided in its ceiling and bottom with arcuate longitudinal guide slots, engage in the spindles for the spools and connecting links which support the spool spindles in such a way that with the same amount of tape wound on the two spools, the spools at a distance from each other can be held, which is slightly larger than twice the radius of the tape winding on each reel, so that the reels can be moved together along the guide slots.
  • the longitudinal dimension of this cassette therefore only needs to be about 4 times the winding radius.
  • Disadvantages are the complex, drive mechanisms required outside the cassette. It is also a magnetic tape cassette for television or sound recording, so that the problem of keeping the tape tension constant in the writing zone does not occur here.
  • the tape runs at a constant speed, without prejudice to the changes in the tape lengths on the reels, because a roller that drives the pre-winding reel is held in contact with the circumference of the tape reel on the pre-winding reel. Therefore, no friction clutch is required with this arrangement (page 11, penultimate line of DE-OS 1 574 439).
  • this embodiment has the disadvantage that with decreasing radius of the unwinding spool, the force of the pressure spring and thus the tape tension in the writing zone increases, which leads to a different typeface since the drive pinion cannot avoid greater slippage with an increased drive force.
  • the invention is therefore based on the object to avoid the above disadvantages and to provide a winding device for tape cassettes for writing utensils, with an unwinder, a winder and a brake to achieve a constant tension in the tape in the writing zone.
  • This object is achieved in that the winding and unwinding on 2 axes of a carrier are arranged in parallel and at a fixed distance from one another and can be moved together, and in that means are provided for the pressing force and the rotary movement from the drive wheel to the winding and the sliding movement on the Transfer carrier.
  • the brake is a wrap-around brake acting on the unwind, which is provided with a lock.
  • the type of wrap brake shown always generates an essentially constant braking torque as after the unwinding state of the unwinding.
  • the looping brake therefore moves with the two spool pins, so to speak, and is therefore able to apply an almost constant braking torque to the unwind, regardless of the cassette housing.
  • the two axes are fixed vertically and parallel on a support and in one in the bottom and / or cover of the Cassette housing arranged in the longitudinal direction guide (slot, groove or the like), wherein means are provided to move the carrier in operation in this groove.
  • the two axes are arranged on a pivotable carrier.
  • a pivotable carrier For example
  • the carrier 3a has vertical axes 3b and 3c, which, for. B. is made in metal die casting or plastic injection molding. Both axes are equipped with a 3d guide pin at their upper end.
  • the carrier 3a is slidably guided in a guide in the bottom of the cassette housing.
  • a mounting pin 3e for a tension spring 4 is attached to the carrier. Via this tension spring 4, the carrier 3a is pressed together with the axles 3b and 3c and the reel 6 or the reel 7 against a drive wheel 3 during operation. As the diameter of the reel 6 increases, the carrier is moved in the longitudinal direction in the direction of the arrow. With the help of the two guide pins 3d, which lie in a longitudinal slot 12 in the cover 2 of the cassette housing 1 and with the carrier 3a guided thereby, the two axes 3b and 3c are guided exactly in the vertical position and the desired winding is thus achieved.
  • the comprehensive wrap brake 8 is also shifted. This brake ensures the uniform tension of the writing tape 9 in the area of the writing zone 10, which is required to achieve a perfect typeface.
  • a fuse 11 prevents z. B. a plate twisting the wrap.
  • the carrier is advanced, for example, with the aid of a return spring (4), which develops the required forces.
  • a return spring (4) which develops the required forces.
  • a compression spring or another means can be used to press the carrier against a drive wheel driving the reel, which can be toothed, corded or made grippy in some other known manner.
  • the axis of the unwinding unwind is now towards the wall of the cassette, i.e. moved outwards, while at the same time and to the same extent the axis of the ever-increasing rewinder moves towards the center of the cassette. This simultaneous shift requires a significantly smaller cassette area than in the previous systems.
  • the distance between the axes must be adjusted to the size of the unwinding diameter so that the two coils can never touch.
  • the carrier 3a executes a pivoting movement and does not require a longitudinal guide in the housing and / or cover.
  • the take-up brake consists of a spring element 8, which acts axially on the take-off 7 and is supported on the inclined counter bearing 13, whereby a braking force which decreases as the carrier 3a is displaced is achieved.
  • the counter bearing 13 is provided with a step 15 on the inclined surface 14 equipped, which enables the axially acting braking force of the spring element 8 is canceled there when the carrier 3a is moved.
  • the winding device according to the invention is suitable for all common belt types and sizes; z. B. commercially available tapes are used, which can be described on one or more levels.
