Definitions

• the invention relates to a tachograph with a flat, parallelepiped-shaped housing and with a registration device provided for the use of diagram disk bundles, in which the individual diagram disks, which are each fastened by means of connecting strips to a base disk and for the passage of a separating knife and the registration organs have a sector-shaped cutout from a chart on the next chart in the chart bundle, are gradually separated from the fixed separating knife from the chart bundle and stacked at a stop, one edge of the section of a chart cooperating with the stop and in which one The stop edge of a diagram disk transported against the stop abuts against the end of the severed connecting strip on the diagram disk side s Diagram disc on the stop is avoided.
• bundles of diagram disks are advantageously used when a process of interest in their context is to be recorded over a longer period of time or if a better resolution of the registrations is to be achieved within a certain temporal registration area than would be possible with a single diagram disk with a relatively narrow registration capacity. Otherwise, the operation of a tachograph is by inserting of diagram slice bundles, which, for example, allow weekly registration, is considerably simplified.
• the uninterrupted registration aimed for with a diagram disk bundle in which the diagram disks are arranged in a staggered manner over a longer period of time is achieved in that the registering elements of the tachograph slide down from a diagram disk to the next diagram chart in the diagram disk bundle after almost one revolution as a result of the sector-shaped sections.
• the further registration is thus carried out without a time offset on a new, as yet unrecorded diagram disc, while the described diagram disc, which is connected by the connecting strip, for example a paper strip, to the last diagram disc or a base disc in the registration process, during the further movement of the diagram disc bundle by means of a cutting knife , which also falls into the section of the described chart and then acts between the described and the next following chart, is separated from the bundle of charts.
• the friction of the separated diagram disc with the remaining and further rotating remaining bundle or with its liner firmly connected to the base disc guides the separated diagram disc against a stationary stop.
• the diagram disks or the diagram disk bundle when they are in the registration position, are arranged essentially horizontally, with the movement of a diagram disk bundle from a removal / Insertion position into the registration position and vice versa by means of a drawer guided in the housing.
• Such a bumping leads to a time delay of the registrations, 1 if the diagram disc bundle is subsequently transported further due to the then increasing transport moment, but can also tear off the diagram disc bundle if the diagram disc gets stuck on the connecting strip, which may not be glued over the entire surface or detached at the edges of the driving means driven by the registration drive and thus interrupt the registration transport of the diagram disk bundle.
• the object of the present invention was therefore to improve the suitability of a tachograph equipped with a drawer for the use of diagram disk bundles as record carriers, in particular to ensure the functional reliability with regard to avoiding a collision of the remaining bundle with a diagram disk separated from the diagram disk bundle, and with means suitable for series production.
• the solution to the problem provides that a spacer provided with a ramp is provided, by means of which the diagram disks separated from the diagram disk bundle and lying against the stop are lifted off the registration level within a certain angular range and that the spacer is in relation to the stop is positioned in such a way that a diagram disk transported against the stop at the end of a registration cycle is raised in such a way that the stop edge of the diagram disk essentially comes into contact with this diagram disk between the connecting strip and the stop edge of a diagram disk abutting the stop.
• Advantageous embodiments of the invention describe the subclaims which are subordinate to claim 1.
• the position of the spacer in relation to the stop assigned to the separated diagram disks, the stroke specified by the spacer and the shape and surface quality of the spacer are selected in such a way that it is ensured that the registrations on the diagram disk still connected to the remaining bundle are offset in time through the impact of this diagram disc on the ramp or due to the braking torque resulting from the friction on the spacer and the connecting strip loaded by pulling the diagram disc not pulling off prematurely or being compressed but rather being cut through correctly by the separating knife and thus timely transport of the The chart is guaranteed until the registration elements slide onto the next chart in the bundle of charts.
• the embodiment in which the spacer is dome-shaped or mushroom-shaped and is attached directly to the separating knife is particularly advantageous in this regard.
• the attachment or formation on the cutting knife is preferably carried out by injection molding; it is also conceivable in the course of the manufacture of the separating knife to mount an individual part serving as a spacer on the separating knife without any appreciable additional outlay. It is also conceivable that the Before the hardening of the cutting knife, the spacer is stamped out of the cutting knife blank. On the other hand, an arrangement or design of the spacer that is independent of the separating knife is possible, for example on the holder of the separating knife or on the registration document assigned to the diagram disk bundles. In this case, training with a resilient holder is also expedient, if appropriate with a certain adjustability of the spacer.
