Definitions

  • the invention relates to a drive device for a type carrier, printhead, magnetic head and similar carriage arrangement which can be displaced along at least one guide rod and can be driven by means of a drive unit, consisting of a drive motor, optionally with a gear, and a drive pulley, via a drive belt or cable is, which is guided over the drive pulley and a deflection pulley arranged in the frame and is attached to the carriage on both sides.
  • a drive unit consisting of a drive motor, optionally with a gear, and a drive pulley, via a drive belt or cable is, which is guided over the drive pulley and a deflection pulley arranged in the frame and is attached to the carriage on both sides.
  • the drive unit is usually mounted in a stationary manner in the frame, and the deflection pulley is guided in a spring-loaded manner in order to generate and maintain the belt or rope tension, which at the same time compensates for expansion of the belt as a result of temperature fluctuations or as a result of longer operating times (see, for example, 4 of US-A-3 496 547).
  • Such compensatory movements take place, for example, in the case of type carrier stop movements or in the case of an uneven magnetic head path, such as occur when driving over journal books, passbooks, etc.
  • the invention has for its object to remedy this situation and to design a drive device of the type described above in such a way that the longitudinal movements of the slide are carried out with significantly increased accuracy of the synchronism and the stepping movements. This object has been achieved with the device according to claim 1.
  • the entire drive unit consisting of the drive motor, which is usually designed as a geared motor, and the drive disk, is arranged as a spring-loaded mass in the direction of movement of the slide, so that all longitudinal interference forces and vibrations of high frequency originating from this unit are reflected in the by spring-drive system formed spring-mass system can react and possibly low-frequency forces are transmitted to the housing via the guide rods.
  • the mass of the drive unit is effective as a damping element, and the slide movement remains unaffected by these interfering forces.
  • all forces occurring in the direction of the slide movement such as belt or rope tension, thrust, acceleration and deceleration of the slide form a closed circuit in the system and are used as reaction forces via the counter bearing of the spring element, i.e. via the guide rod (n ) derived in the frame.
  • the drive unit is either rotatably guided on a guide rod or on two parallel guide rods and is each supported by means of a compression spring against a corresponding stop on the guide rod.
  • a carriage 10 with a magnetic head 12 is guided in a longitudinally displaceable manner on two parallel guide rods 14, 16.
  • the ends of the guide rods 14, 16 are supported on both sides in a frame 18.
  • a drive unit 20 consisting of a geared motor 21 with a drive pulley 22, is used the drive disk 22 and a deflection disk 26 mounted at the opposite end in the frame 18 and fastened at its ends to the carriage 10 so that it forms a closed loop.
  • the geared motor 21 is likewise guided in a longitudinally displaceable manner on the guide rods 14, 16 by means of a motor carriage 28, which is supported by two compression springs 30 against two disks 32 which are fastened on the guide rods 14 and 16, respectively.
  • the compression springs 30 By means of the compression springs 30, the rope 24 is thus kept constantly under a certain tension, and changes in length of the rope 24 due to expansion or temperature fluctuations are automatically compensated in this way.
  • the geared motor 21 can be reversed and, in accordance with the control signals supplied, effects a continuous or step-wise reciprocating movement of the carriage 10 over a predetermined path. Vibrations or similar disturbing forces occurring in the geared motor 21 in the direction of the guide rods 14, 16 are effectively damped by the mass of the drive unit 20 and, unless they are already absorbed by the sprung mass of the drive unit 20, reach the guide rods 14 via the compression springs 30 , 16 and from there directly into the frame 18 without the movement of the carriage 10 being impaired thereby. Since the deflection disk 26 is rigidly mounted in the frame 18, it does not react to transverse forces which act on the carriage 10, for. B.
  • the deflection disk 26 can not impair the synchronism of the carriage feed, but such transverse forces, as far as they are converted into longitudinal forces via the cable 24, are absorbed by the inertia of the geared motor 21.
  • the geared motor 21 guided on the guide rods 14, 16 with respect to the longitudinal vibrations and disturbing forces thus forms an independently oscillating spring-mass system, which ensures a very precise synchronization of the carriage movements.
  • the magnetic head carriage 40 with the magnetic head 42 and the gear motor 51 with the associated drive disk 52 are guided in a longitudinally displaceable manner on two parallel guide rods 44, 46.
  • the guide rods 44, 46 are mounted in side plates 48 of the device.
  • the magnetic head 42 is pivotally mounted by means of bearing pins 42a with locking screws 42b in a head carrier 41, which in turn is pivotably guided in the magnetic head carriage 40 by means of an axis 43.
  • a spring 43a exerts a constant torque on the head support 41, so that the magnetic head 42 bumps when driving over the passbook surface, z. B.
  • a flat cable harness 55 connects the magnetic head carriage 40 to the magnetic head 42 and at the same time acts as a parallel guide for the magnetic head 42 which is pivotably guided in the head carrier 41 (cf. also FIG. 2A). Regardless of the respective pivot position of the head support 41, the magnetic head 42 therefore always maintains its position parallel to the plane of the magnetic strip.
  • Another flat cable harness 57 is used for the electrical connection between the magnetic head carriage 40 and a holder 59 on the geared motor 51, from which in turn corresponding cable connections lead to the machine housing. This cable routing is used so that the entire arrangement shown in FIG. 2 can be replaced as a complete structural unit.
  • a drive unit 50 is arranged, consisting of the geared motor 51 and its drive disk 52. Via the drive disk 52 and a deflection disk 54 mounted in the side plate 48 at the opposite end of the guide bars 44 a rope 56 is guided, the ends of which are attached to the magnetic head carriage 40 and which thus forms a closed loop.
  • the geared motor 51 with the drive disk 52 is guided in a longitudinally displaceable manner on the guide rods 44, 46 by means of a motor carriage 58 and is supported on the guide rods 44, 46 by a spring 60 against a C-disk 62.
  • FIG. 2 shows a ramp surface 66 on which the magnetic head 42 is lifted off the record carrier in the area of the right end position of the magnetic head carriage 40 by means of a roller 68 attached to the head carrier 41, so that the inserted passbook can be removed and a new one inserted.
  • the springs 60 exert a constant force (directed to the right in FIG. 2) on the motor carriage 58 and ensure the constant maintenance of the tension of the rope 56. In addition, changes in length of the rope 56 are automatically compensated for by the springs 60 without the need for readjustment is.
  • the vibrations and other disturbing forces that occur parallel to these during the back and forth movement of the magnetic head carriage 40 along the guide rods 44, 46 in the geared motor 51 are, as has already been described with reference to FIG. 1, already in the region of their origin, namely by spring-loaded mass of the drive unit 50 damped and can therefore not be transferred to the magnetic head carriage 40.
  • the adjustment speed and positioning accuracy of the magnetic head carriage 40 is therefore not affected by this.
  • the occurring longitudinal disturbing forces rather, unless they are already absorbed by the spring mass of the drive unit 50 and the springs 60, as forces of very low frequency via the guide rods 44, 46 and the boards 48 into the frame of the device.
