Definitions

  • the invention relates to a device for transporting separated sections of an endless record carrier from a writing mechanism according to the preamble of claim 1.
  • a device of this type is known from IBM Technical Disclosure Bulletin Vol. 14, No. 12, May 1972, pages 3751 and 3752.
  • the separated sections are grasped by means of their own transport device and transported away to the side.
  • the transport device is driven by a complicated mechanical transmission mechanism from the continuously rotating drive shaft of the writing mechanism.
  • a device for transporting sections of a record carrier from a writing mechanism which comprises a cutting unit for separating the sections from the record carrier, which in a cutting stroke and a return stroke transverse to the transport direction of the record carrier across its width is movable.
  • the cited document contains no information as to how the separated sections can be transported or output after the cutting process.
  • DE-A-35 22 022 shows a printing unit with a knife connected downstream of the printing area and several pairs of discharge rollers for the paper sections.
  • the type of knife is not described in detail. This document does not indicate whether the drives for knives and conveyor roller pairs work together.
  • DE-A-32 02 264 shows a paper cutting device in which a cylindrical rotary knife which extends over the entire printer width is moved with the same drive motor as the paper transport roller. The knife is driven in one direction of rotation and the transport roller in the opposite direction of rotation. A freewheel is assigned to both drives.
  • the invention has for its object to provide a device of the type mentioned, in which the separated sections can be automatically removed from the writing mechanism with simple means.
  • This arrangement has two major advantages. On the one hand, no separate drive motor is required for the transport of the separated sections. Rather, the movement of the cutting unit on its return stroke is used to move the transport elements and, through them, the separated sections. On the other hand, there is no need to control the drive for the transport elements. These are inevitably only moved when the cutting process has ended and the separated section can thus be removed from the writing mechanism without problems.
  • Such a coupling of the transport elements to the cutting unit can be achieved in a simple manner in that the gear arrangement comprises a one-way clutch, for example a freewheel.
  • the gear arrangement comprises a one-way clutch, for example a freewheel.
  • the transport elements can be permanently connected to the cutting unit.
  • the freewheel With a suitable installation of the freewheel, the movement of the cutting unit is not transmitted to the transport elements during the cutting stroke of the cutting unit, while on the return stroke the freewheel blocks and transmits the movement of the cutting unit to the transport elements.
  • the coupling between the cutting unit and the transport elements is possible in a simple manner in that the cutting unit comprises a support for a knife which is displaceably guided transversely to the transport direction and which is connected to the one-way clutch by a cable pull which at least partially wraps around a drive element of the one-way clutch.
  • a tension spring can be arranged in the cable pull, which ensures suitable pretensioning of the cable pull even without complex adjustment of the pretension.
  • the transport elements are expediently formed by transport rollers which can be driven in opposite directions and which act in pairs and which form a roll nip for the separated sections of the recording medium.
  • one of the transport rollers of the or each pair of rollers is mounted on a rocker arm which is pivotably mounted about a pivot axis parallel to the roller axis and is pretensioned into its position remote from the other transport roller.
  • Means are provided, which are the transport rollers of the pair of rollers to move towards each other when driven by the cutting unit. As long as the transport rollers are not driven, they are lifted from each other so that the section to be separated can be inserted between the transport rollers without friction. If the transport rollers are to be driven on the return stroke of the cutting unit, the transport roller mounted on the rocker arm is pressed against the stationary transport roller by pivoting the rocker arm. As a result, the section to be separated is gripped and advanced by the transport rollers.
  • the gear arrangement comprises an intermediate gear arranged coaxially to the pivot axis of the rocker, which meshes on the one hand with a gear which is non-rotatable with an output element of the one-way clutch and on the other hand with a gear which is non-rotatable is connected to the shaft of the transport roller mounted in the rocker arm and is intended for engagement with a same gearwheel seated on the shaft of the other transport roller.
  • the rocker arm By rotating the idler gear, which is constantly in engagement with the gear wheel, which is connected in a rotationally fixed manner to the transport roller mounted on the rocker arm, the rocker arm is first pivoted until the transport roller mounted in it on the other transport roller or on the one between the two Roller lying section abuts. Since the rocker can no longer deflect, the torque of the idler gear is transferred to the transport rollers, which eject the cut section.
  • the single figure shows a perspective schematic representation of the transport device according to the invention.
  • a guide rod 10 can be seen, which is held in a frame, not shown, of a writing mechanism, for example a receipt printer, and extends transversely to the transport direction indicated by the arrow A for a recording medium.
  • the print head and other parts of the writing mechanism are not shown.
  • they can be designed in the form shown in German Offenlegungsschrift 23 43 858.
  • a knife carriage 12 is slidably mounted on which a roller knife, not shown, is mounted.
  • a thin rope 14 is suspended on the knife carriage 12, which is guided over three deflection rollers 16, 18, 20 and with a plurality of windings loops around a cylindrical sleeve-shaped drive element 22 of a freewheel, generally designated 24.
  • a tension spring 26 is arranged between the one end of the cable and the knife carrier 12.
  • a transport device is used to advance the separated section 28 of an endless record carrier, which is otherwise not shown. It comprises lower transport rollers 32, the sit rotatably on a stationary shaft 34 which carries a gear 36 at one of its ends. With these lower transport rollers 32, two upper transport rollers 38 cooperate, which are non-rotatably seated on a shaft 40, which is rotatably mounted in a rocker 42 and carries a gearwheel 44 at one end which is intended for engagement with the gearwheel 36.
  • the rocker 42 is pivotable about a pivot shaft 46 parallel to the shafts 34, 40 and is mounted thereon with friction in the frame of the writing mechanism and is biased by a tension spring 48 into a position in which the upper transport rollers 38 are separated from the lower transport rollers 32 are lifted off. In this position, the section 28 to be separated can be inserted into the gap between the lower and upper transport rollers 32 and 38 without hindrance.
  • the pivot shaft 46 carries at one end an intermediate gear 50 which is in constant engagement with the gear 44 on the upper transport roller shaft 40 and also constantly meshes with a gear 52 which sits on the output shaft 54 of the freewheel 24.
  • the gears 44, 50 and 52 remain in constant engagement with one another in this arrangement even when the rocker 42 is pivoted.
  • the gears 44 and 36 on the transport roller shafts have the same diameter. The diameters of their pitch circles correspond to the outside diameters of the rollers 32 and 38, respectively.
  • the print head After completion of a printing process, during which the knife carriage 12 is in a rest position to the right in the figure, outside the path of movement of the print head, the print head, not shown, extends beyond the end of its normal path of movement and is thereby automatically coupled to the knife carriage 12. In an opposite movement, it then drags the knife carriage in a cutting stroke in the direction of arrow B across the record carrier, the roller knife (not shown) separating the printed section 28 from the record carrier. During this movement, the sleeve 22 of the freewheel 24 is freely rotated in the direction of arrow C via the cable 14. The output shaft 54 is not moved, so that the transport device 30 remains at rest.
  • the sleeve 22 of the freewheel 24 is moved by the cable 14 in the direction of arrow D. In this position, the freewheel 24 locks, so that the rotational movement of the sleeve 22 is transmitted to the output shaft 54 of the freewheel 24.
  • the rotational movement of the output shaft 54 is transmitted via the gear 52 to the intermediate gear 50 and from there to the gear 44.
  • the rocker 42 which has been raised by the tension spring 48, is initially pivoted downward until the upper transport rollers 38 rest on the severed section 28 and press it against the lower transport rollers 32.
  • the gears 44 and 36 come into engagement with one another so that the lower transport rollers and the upper transport rollers are driven at the same speed but in opposite directions and transport the separated section detected between them in the direction of arrow A out of the writing mechanism.
