Definitions

  • the invention relates to a device for shredding pourable feed material according to the preamble of patent claim 1 and a method for opening such a device according to patent claim 12.
  • Devices of this type belong to the field of mechanical process engineering and are used to convert starting materials into an intermediate or final product of a predetermined shape and size.
  • the aim of the conversion process is to produce a product that is uniform in terms of shape and size within narrow limits. This is achieved, among other things, by arranging a sieve downstream of the shredding zone, the sieve passage of which meets the requirements of the product within the specified tolerances.
  • the shredding operation means that the parts that come into contact with the feed material in particular are exposed to wear and therefore have to be replaced at regular intervals.
  • cleaning, maintenance and repair work is required, all of which require good accessibility to the interior of the device.
  • the resulting downtimes of a device are to a large extent a determining factor in economical shredding operations. It is therefore in the interest of the operators of such devices to be able to carry out such work as quickly and safely as possible.
  • a cutting mill with a rotor is known, the rotor tools of which interact with stator tools arranged stationary on the mill housing to shred the feed material.
  • the rotor is surrounded by a sieve over the lower peripheral section, while the upper peripheral section serves to feed the feed material.
  • the housing merges into a suction trough, the funnel-shaped peripheral walls of which guide the shredded material to the bottom of the trough, where it is removed from the device via a suction line in the air flow.
  • the object of the invention is to ensure optimal accessibility to the interior of the device in order to be able to carry out work on the rotor and sieve efficiently and safely.
  • the invention is based on the basic idea of opening a device according to the invention in two steps.
  • a first step the screen holder is pivoted about a first pivot axis, whereby a partial opening of the device is achieved;
  • a second step the screen holder is pivoted about a second pivot axis until full opening is achieved.
  • the special feature is that the two pivot axes run transversely to each other, which creates kinematic conditions that enable adaptation to existing spatial conditions through a combination of different pivoting movements in different spatial directions.
  • the existing one The space available can be used optimally in this way, with the advantage that the screen holder of devices according to the invention can be swung open further and the rotor inside the device is therefore more accessible.
  • a further advantage of the invention is that even sieves that extend over more than half the circumference of the rotor can be swung open sufficiently to provide the staff with sufficient working space when carrying out the above-mentioned activities.
  • the two pivoting movements can be carried out at least partially simultaneously.
  • the screen holder first pivots about the first axis and then about the second axis, which clearly structures the process sequence and thus simplifies the control of the device.
  • the advantage is that the first pivot axis runs parallel to the rotor axis, so that when the screen holder is pivoted about the first pivot axis, the sieve is lifted evenly perpendicular to the rotor axis, thereby creating more space for pivoting about the second pivot axis.
  • the first pivot axis can be defined, for example, by two points spaced apart from one another, which are formed by a first pivot bearing and a second pivot bearing, both of which are attached to the housing of the cutting mill, preferably on the upper knife bar.
  • the first pivot bearing is designed in such a way that the screen holder can be detached from the pivot bearing.
  • the first pivot bearing can have a bearing pin which is coaxial with the first pivot axis and which engages in a coaxial bore in the screen holder. By pushing the bearing pin back axially, the first pivot bearing is unlocked and the screen holder is released for pivoting about the second pivot axis.
  • the second pivot bearing is preferably such that it enables both the screen holder to pivot about the first pivot axis and the second pivot axis. It therefore has at least two degrees of freedom, which means that the machine design can be simplified due to the dual function of the second pivot bearing.
  • the second pivot joint can be formed by a ball joint, the ball head of which is rigidly attached to the housing of the device in alignment with the first pivot axis and which interacts with a joint socket arranged on the sieve holder.
  • the second pivot axis is also preferably defined by two spaced-apart points, each of which is formed by a pivot bearing, whereby one pivot bearing can be formed by said second pivot bearing with two degrees of freedom and / or the other by a third pivot bearing also with two or three Degrees of freedom, which is explained in more detail below.
  • the second pivot axis is aligned vertically, i.e. following gravity. This prevents the sieve holder from opening automatically and uncontrollably after it has been released from the first pivot bearing, which represented a source of danger for personnel and the device.
  • the two pivot axes are perpendicular to one another;
  • a perpendicular arrangement of the two pivot axes to one another represents a preferred embodiment, since in this way a device according to the invention can be opened very quickly and widely and extremely precisely.
  • first pivot axis and second pivot axis are arranged relative to one another in such a way that they lie in a common plane at least after pivoting about the first pivot axis and thus when the second position is reached.
  • first pivot axis and second pivot axis intersect at a point which preferably coincides with the second pivot bearing. Only when the two pivot axes have assumed this relative position to one another are the kinematic requirements met in order to be able to begin the pivoting process about the second pivot axis.
  • this circumstance can be used to make the process of opening the device safer.
  • the first pivot axis and second pivot axis are spaced apart from one another and therefore do not form an intersection.
  • the second pivot axis is moved relative to the first pivot axis until a common intersection occurs, i.e. the two pivot axes lie in a common plane.
  • the sieve holder cannot be moved around the second pivot axis, so that an automatic locking of the screen holder is achieved, which prevents the pivoting process about the second pivot axis from being carried out unintentionally prematurely.
  • the second pivot axis parallel to the first pivot axis during the pivoting process, i.e. to move it translationally.
  • this is achieved, for example, by the second pivot axis being defined by a third pivot bearing, which, in addition to the pivoting movement about the second pivot axis, has a further degree of freedom, namely a rotational movement through the third pivot bearing about a rotation axis parallel to the first pivot axis.
  • the third pivot bearing also enables the compensation of linear displacements in the direction of the second pivot axis as a third degree of freedom in order to prevent constraints between the pivot drive and the screen holder.
  • This advantage is particularly important in linear drives whose driven part, such as a push rod, does not follow a circular movement around the first pivot axis, but rather moves in a straight line.
  • linear drives are preferred means for pivoting the screen holder about the first pivot axis, since they can be used to easily and sensitively control the pivoting movement.
  • the open side of the screen holder facing the rotor is bounded at the top by an upper edge and at the bottom by a lower edge.
  • the sieve holder connects to the housing of the device with its upper edge, which is assigned to the first pivot axis or the upper knife bar, and its lower edge, which is assigned to the lower knife bar.
  • the upper edge and the lower edge are approximately diametrically opposed to each other with respect to the rotor axis, with the upper edge having a horizontal offset compared to the lower edge.
  • the upper edge and lower edge together define a connection plane which is inclined at an angle ⁇ relative to a vertical, with the advantage that when pivoting about the first pivot axis, the weight of the screen holder supports the pivoting movement.
  • the angle ⁇ is preferably between 10° and 40°, in particular between 20° and 30°.
  • the screen holder is pivoted by a maximum of 30° about the first pivot axis, which results in the opening angle ⁇ between the screen holder and the housing of the device.
  • the resulting geometric conditions make it possible to begin pivoting about the second axis.
  • the extent of the pivot after the first step also determines the inclination of the sieve holder after the second step. From this aspect, further preferred embodiments of the invention provide for the screen holder to be pivoted about the first pivot axis up to a maximum of 40°, in exceptional cases up to a maximum of 60°.
  • the degree of pivoting of the sieve holder about the second pivot axis determines the accessibility to the interior of the device.
  • pivoting by at least 90° is advantageous, preferably by 90° to 180°
  • the vertical distance a of the upper pivot axis to the rotor axis corresponds approximately to the vertical distance b of the rotation axis to the third pivot bearing. This spacing ratio has proven to be extremely favorable when pivoting the screen holder, particularly about the second pivot axis.
  • a device according to the invention in the form of a cutting mill 1 is shown in an operational state, i.e. in a first position with the sieve holder 2 closed.
  • the sieve holder 2 can be swung open from the housing 3 in two steps become.
  • the Fig. 6 to 9 show the partially opened cutting mill 1 in a second position in a state after completion of the first step Fig. 10 to 12 the cutting mill 1 in a third position with the screen holder 2 completely open after completion of the second step.

  • the rotor 7 is driven by a motor 22, which sets the drive shaft 8 in rotation via drive belts (not shown) and a multi-groove pulley (not shown) seated on the drive shaft 8.
  • the cutting mill 1 has a funnel-shaped material inlet 13 upstream of the rotor 7, which is delimited in the axial direction by the transverse walls 4, 4 ', each of which is covered with a wear plate 21 in this area.
