Definitions
- the invention relates to a device for shredding document material, which has a rotating cutting roller with at least one row of teeth formed from teeth of different tooth heights and a firmly supported toothed bar which interacts with the cutting roller and is profiled in accordance with the teeth of the cutting roller.
- Document material is understood to mean all types of documents made of film, sheet and ribbon material.
- the material can also be different and e.g. Paper, plastic or the like include.
- Plastic tapes of all kinds play an important role as document material today, e.g. Magnetic tapes, microfilm tapes and the like.
- the document material mentioned occurs in significant quantities in different places and has to be used for different reasons,. e.g. in terms of secrecy or removal due to aging and obsolescence. Here, however, it is necessary that the destruction takes place in such a way that no information can be extracted from the document material, even if it would fall into unauthorized and unauthorized hands.
- a particularly reliable impossibility of extracting information from document material is that To make document material to be destroyed unusable by breaking it down into extremely small parts.
- Various designs are known for this purpose, which break down the document material into more or less small parts.
- a high-speed rotor is used, which is equipped with one or two rows of teeth, which interact with a fixed toothed rack.
- the teeth of one row of teeth are alternately designed with different tooth heights.
- the toothed rack is also crenellated according to this tooth sequence. So that a uniform shredding of the document material is achieved, a feed pad is provided, on which a feed roller is arranged.
- the tooth height of the small teeth measured from the tooth base on the circumference of the roller body, is equal to or less than the difference between the tooth heights of a larger and smaller tooth.
- the cutting roller 1 shown in FIG. 1 is a schematic illustration, since an accurate graphic representation is not possible in view of the small tooth height.
- the cutting roller 1 has, see Fig. 2, a number Rows of teeth extending axially across the width of the cutting roller 1, of which two rows of teeth 2, 3 are shown in FIG.
- the rows of teeth 2 and 3 are composed of teeth, of which a larger tooth 4 is followed by a smaller tooth 5, which is followed by a larger tooth 4.
- the larger teeth 4 of all rows of teeth 2, 3 form protruding sections 6 on cutting roller 1, while the smaller teeth 5 of all rows of teeth 2, 3 form recessed sections 7 on cutting drum 1.
- the tooth height, see FIG. 2, of the larger teeth 4 is denoted by a and the tooth height of the smaller teeth 5 by b.
- This equation states that the difference in the tooth heights of the larger and smaller teeth 4, 5 must be greater than the tooth height of the smaller tooth 5. If this condition is observed on the cutting roller 1, the undesirable case of the formation of long stripes cannot occur, even if the feed is not set correctly or is not working properly.
- This condition can also be represented as the ratio between the tooth heights of the two teeth 4, 5, which according to the above statements must be at least 2.0. Appropriate values of this ratio are between 2.1 and 3.5.
- the cutting roller 1 is supported in two bearing blocks 11, 12 by means of roller bearings 9, 10.
- the two bearing blocks 11, 12 are connected to one another by a toothed strip 13, which has a profile which corresponds to that of the protruding and recessed parts 6, 7 of the cutting roller 1 Right.
- the toothed rack 13 can be adjusted in its distance from the cutting roller 1.
- FIGS. 1 and 2 are not a dimensionally correct representation, it should be mentioned that the tooth height of the larger teeth 4 is chosen to be less than 1 mm. Accordingly, the difference A is of the order of a few tenths of a millimeter.
- the speed of the cutting roller 1 can be chosen small, e.g. less than 250 rpm, but preferably less than 150 rpm. The low speed also means that the power for driving the cutting roller 1 is small and is less than 100-200 watts. Nevertheless, the performance of a cutting roller 1 designed in this way is very high and comparable to the performance of known designs which, however, require a performance which is at least a power of ten higher.
- FIGS. 1 and 2 schematically shows a machine for shredding document material, which is equipped with a cutting roller 1 according to FIGS. 1 and 2.
- the machine consists essentially of three parts, a shredding part I, a collecting part II and a ventilation part III.
- the shredding part I which is shown in section, has a cutting roller 1, which is arranged at the end of a practically vertical feed nip 14 through which the document material is introduced. In this case, the document material is fed through its own weight. In spite of the lack of a feed device, a perfect comminution of the material is achieved since the material is arranged on the roller body of the cutting roller 1 Teeth 4, 5 have the tooth heights according to the invention.
- the toothed rack 13 is arranged at the end of the feed gap 14.
- the cutting roller 1 is driven by a drive motor 15, for example a gear motor, via an enveloping drive 16, for example a toothed belt drive.
- the shredded material is collected in a bag 17 arranged in the collecting part II.
- a fan arranged in the ventilation part III generates a suction flow through which the shredded document material reliably reaches the sack 17.
- the machine can be provided with castors so that it can be used in different places.
- parts I - III of the machine can be arranged in another way, e.g. lying.
- a feed device can also be provided in the gap 14, in particular when the gap 14 is not arranged vertically, but rather at an angle or horizontally. It is essential, however, that in any case the cutting roller 1 is designed in the manner described in order to take advantage of such a machine, i.e. low drive power, low speeds of the cutting roller 1 with a correspondingly low noise level and reliable shredding of the document material into the smallest fragments.
- the cutting roller 1 can expediently be produced from a single hardened piece of material.
- the walls of the machine according to FIG. 3 can expediently be made of light metal or plastic.
