Definitions

  • the invention relates to a paper shredder with a rotor which is rotatably mounted in a housing with a filling opening and is equipped with shredding tools and has a horizontal axis and an outlet grate and an outlet opening of the housing associated with the outlet grate, the grate being pivoted sideways about a grate axis running parallel to the rotor axis. It also relates to a method for operating this paper shredder.
  • DE-A-915 520 describes a chopper, namely a crushing mill for chopping field crops.
  • the actual shredding process with this device is not caused by tearing, but by breaking and preferably by grinding the crops, which is the optimal shredding treatment for crops.
  • the good, field crops is fundamentally different from the good "paper” in terms of its specific behavior with regard to crushability and the treatment to be based on it.
  • the purpose of this known proposal is to enlarge the abutment mounting area. By folding in the sieve to be swung out, a screening of the ground material is carried out; if this is not necessary, the sieve remains folded down.
  • the material outlet is not below the rotor, but above the rotor center plane, always directly upstream of the material inlet in the direction of rotor rotation. This means, among other things, that all material that has entered the crushing mill must initially pass through more than half of the treatment path with unchangeably narrow grinding tools in the sense of a grinding process, which already achieves a comparatively fine, constructionally uncontrollable degree of grinding.
  • DE-A-2 516 014 describes a shredding machine which is intended for waste and other waste.
  • the rotor is assigned a grinding path which is not permeable but has ribs running approximately parallel to the rotor axis and a grinding grate which is permeable to comminuted material.
  • the grinding grate which has roughly axis-parallel grate bars, can be moved horizontally out of the lower part of the housing on rails.
  • the grinding track and the grating essentially enclose the lower rotor half in the order specified. While the grinding grate should be approximately the same distance from the impact circle of the rotor tools everywhere, it is provided that the distance between the grinding track and the rotor be made smaller in the direction of rotation of the rotor. If there are hard materials that cannot be shredded in the processed material, the grinding track can be swiveled away from the rotor for a short time.
  • the machine known from DE-A-2 516 014 can also be used for crushing coarse comminution material, such as bulky waste, and even for crushing tough comminution material, such as used tires.
  • the crushing takes place essentially through the impact path, while the grinding grate is completely moved out of the action area of the rotor.
  • the grinding path should be arranged just so far from the impact circle of the rotor that a certain amount of re-crushing is effected but there is no fear of the machine blocking.
  • the grinding track and grinding grate are moved out or swung out of the effective range of the rotor and the rotor tools are only brought into engagement with a tear-off comb or an anvil edge.
  • the direction of rotation of the rotor of the known machine must be reversed.
  • the changeover requires a time-consuming and energy-intensive braking of the fast, e.g. with 1500 revolutions per minute, running rotor. It will also be necessary to switch off the rotor if the grinding grate has been moved out of or into the working position.
  • a major disadvantage of the known machine is that the grating in its position moved out of the operating position hinders the removal of the comminuted material.
  • the first half of the grate in the direction of rotation of the rotor is slightly moved away from the rotor when the machine is in operation, a circularly narrowing working area is created between the rotor and the grate, in which, when the machine is used to shred normal waste or paper, the volume that increases greatly during processing would jam well and jam.
  • the second grate basket half is slightly moved away from the impact circle of the rotor tools, there is an opening wedge between the rotor and grate, but the material running off the first grate does not get into the opening wedge at all, but accumulates in front of the removed second grate.
  • the known machine is therefore unsuitable in its design for shredding garbage, paper and similar light material.
  • Paper shredders must be equally suitable for tearing up individual paper, more or less large bundles, whole files and even goods delivered in bags.
  • the size of the shredding is subject to very different requirements depending on the type of goods entered.
  • a relatively coarse shredding, for example, is sufficient if it is only a question of feeding the paper for further processing. In some cases, smooth paper only needs to be processed to make it pressable.
  • considerable demands are placed on the fineness of the crushing when shredding secret or personal files. The finer the material is to be shredded, the greater the time and energy required for the shredding work. It is therefore of interest to be able to adapt the machine to the respective requirements at short notice and with the rotor running. This is especially true when smaller batches of goods of different types have to be processed one after the other. In order to meet these requirements, three successive shredders have been used in practice up to now, and the processed goods have been processed step by step to the desired final state.
  • the invention has for its object to improve the paper shredder mentioned at the outset so that it can shred comminution material of a changing type to a respectively specified fineness with the cheapest possible efficiency, determined by the expenditure of energy, time and the fineness of the chips and converting the requirements accordingly when the rotor is running or is to be adjusted.
  • the grate consists of two halves divided approximately in the vertical plane of the rotor axis and is arranged below the rotor, that the second grate half in the direction of rotation of the rotor is completely out of the effective range of the rotor tools with the release of a discharge path for approximately tangential or horizontal the comminuted material coming in and ready for use at this point in time is to be pivoted upward, and that the first half of the grate in the direction of rotation of the rotor is to be locked in different pivoting positions relative to the impact circle of the rotor tools.
  • both grate halves are brought into the working position on the impact circle of the rotor tools for fine shredding, that with coarse material and / or coarser tearing, the second grate half is rotated out completely in the direction of rotation and that at even larger pieces of material and / or even less fine tearing the first half of the grate, especially gradually, e.g. is gradually swung away from the impact circle of the rotor tools.
  • the paper shredder with the rotor running - this can have, for example, a run-down time of half an hour - all requirements for fineness of the chips produced, processing time and the lowest possible energy expenditure for different types of paper goods can be adapted in a few simple steps.
  • even smaller batches of different types can be processed economically one after the other.
  • the first half of the rust in the direction of rotation of the rotor must be locked in various swivel positions to the impact circle of the rotor tools.
  • the relative position of counter tools attached to the grate can be adjusted depending on the pivoting position of the grate halves to the impact circle of the rotor tools.
  • the gradual or continuous setting of the first half of the grate in different pivot positions makes it possible to process increasingly coarse material and to achieve increasingly coarse chips.
  • Such an opening wedge is very favorable in the case of paper which increases in volume during processing. If, finally, the first half of the grate was completely swung out of the action area on the impact circle of the rotor tools, there would be practically no tearing effect without switching on additional tools.
  • the machine according to the invention therefore has a tear-off comb or an anvil edge in front of the entrance to the first half of the grate, which can optionally be inserted or pivoted into the effective range of the impact circle of the rotor tools.
  • the paper shredder according to the invention includes a rotor 4 with a horizontal axis 5 which rotates rapidly in operation in a housing 1 with a filling opening 2 and is equipped with shredding tools 3 and which is to be loaded with the material to be shredded, and a two grate halves 6 arranged below the rotor 4 and 7 existing outlet grate and an adjoining outlet opening of the housing 1.
  • the two grate halves 6 and 7 are divided approximately in the vertical plane of the rotor axis 5 and essentially enclose the lower rotor half.
  • the grate halves 6 and 7 can be swiveled out laterally by grate axes 8 and 9 which are horizontally mounted approximately at the height of the rotor axis 5.
  • the second grate half 7 should be raised so far above the above-mentioned horizontal tangent that when the first grate half 6 in use is rotated horizontally by the rotor 4 or the grate half 6, the material does not hit the second grate half 7.
  • the first grate half 6 in the direction of rotation 15, on the other hand, does not need to be swung out as far as the second grate half 7, but only as far as the dash-dotted position, with the aid of its hydraulic arrangement 13 (along the indicated pivot line), since when the first grate half 7 is lifted off, the comminuted material only needs to be swung out the area of the adjacent vertical tangent of the impact circle 16 falls.
  • the in Direction of rotation 15 first grate half 6 in various intermediate positions perform valuable services.
  • further tools for example an anvil flap 19 to be moved in or into the effective range of the impact circle 16, are required for comminuting the material.
  • the material is then comminuted between the rotor tools 3, which are pushed radially outward by centrifugal force, and the anvil edge 20.
  • a hydraulic cylinder arrangement 21 can also be provided to adjust the anvil flap 19.
  • the housing 1 is also made so large in the lower region that the parts which may be swiveled out can be accommodated within the housing and during the Swinging out the operator can not be injured by material thrown from the rotor.
