Definitions

  • the invention relates to a device for cutting powdery to granular and / or granular or flaky sacks containing paper, plastic, jute or the like, and for loosening up and separating the goods from or from the sack or its parts, Consisting of a feeder housing with a cutting device, a sieve drum arranged in a housing with separate outlets for the bag parts, the material to be emptied, and occasionally for oversize particles to be separated.
  • DE-AS 1 209 951 discloses a sack tearing and emptying device in which the filled sack is comminuted and fed via a chute to a screening device with which the sack contents are separated and screened from the sack material.
  • the device is characterized in that in a so-called «knife roller housing ⁇ side by side and in parallel, two counter-rotating knife rollers arranged on the circumference with radial knives are arranged in such a way that the knives mesh with one another.
  • An essentially horizontally mounted sieve drum which widens conically in the direction of the outlet, is provided as the sieve device in order to be able to achieve good conveying conditions within the drum without special design of the drum internals, which are otherwise only given when the drum is inclined.
  • the cut sacks are fed into a discharge chute over the enlarged area of the drum, while the sieve below the sieve screw is picked up by a collecting screw and pulled off from it, for example by a pneumatic conveying device.
  • a disadvantage of this device is that the sacks are inserted between the counter-rotating knife rollers practically without an upstream, separate rectification, so that the sack does not always get optimally aligned between the knife rollers.
  • the knife rollers which provide a plurality of knife stars standing gap after gap, shred the sacks into pieces of uncontrolled size with predominantly torn edges.
  • a particular problem is for all cutting devices, the knives of which are to cut into the sack from approximately the same depth from above and below, if the sack is damaged during transport to the device by external influences, so that the volume, in particular the thickness of the sack, is reduced and a so-called "duffel bag" arises.
  • the object of this invention to name a device of the type described at the outset, which prevents the bags from tearing into pieces of undefined size, and into cut parts which are essentially size-determined by the knife and bag guide, also in the case of Less filling separates, the device should enable a practically complete separation of the material to be emptied from the bag parts and, moreover, a uniform discharge of the separated material, mainly over the first third of the sieve drum.
  • the solution to this problem provides that in the feed housing the bottom of a guide chute provided with openings for the knives is pivotable about an axis fixed on the inlet side, the load-dependent position of which is inclined in the direction of the feed area of the knives by at least one support directly or indirectly on the feed housing , resilient element is determined so that - regardless of the weight or the thickness of the sack dependent on it - the inclination of the bottom is set for a practically equal depth of penetration of the knives arranged at the top and bottom of the sack, the knives being paired coaxially and peripherally facing each other, are arranged in the feed housing, and that in the discharge direction of the sieve drum, at least this is provided over one part of its length, starting from the feed side, with one or more storage ring (s).
  • the proposed paired coaxial and peripheral knife arrangement ensures, in conjunction with the directional chute, the separation of the sack into strips of essentially constant size, the omission of the known “gap-to-gap arrangement of the knives substantially reducing the forces acting perpendicular to the sack passage direction, which leads to smooth cut limits instead of the annoying tear edges.
  • the provided retaining rings enable the setting of a practically continuous discharge of material over the first third of the length of the sieve drum.
  • the resilient element For the design and selection of the resilient element, it is provided that its spring characteristic is adjustable and that the resilient element can be designed as a gas and / or oil pressure spring or the like.
  • the knife shafts carrying the knives are mounted in pairs in opposite directions in the housing in fixedly assigned guides and a knife is interchangeably fixed by the knife holder on each emerging shaft end, that the bearing of each knife shaft in the exit region from the guide forming a support sleeve Double roller bearings ensure that the end region of the shafts is connected to a conical, in the region of the smaller diameter, each with a clamping sleeve that converts into a thread, and that this sleeve has two interlocking clamping plates with passages corresponding to the clamping sleeve, including the interposed knife, that can be pushed on and are assigned fixable by the clamping nut.
  • This design enables a simple change of the individual knives, which are preferably designed so that they are ground on one side in a conical shape, the flat side being aligned with the flat side of the opposite knife, and that the periphery of the knife is designed with wavy cuts.
  • the number of cuts and their shape are ultimately determined by the goods stored in the bag.
  • the shaft grindings have the advantage that the knife disks with the same diameter can be exchanged in the coaxial direction or can be exchanged parallel to the axis between the shaft ends, offset in a cross.
  • Each knife shaft is usually driven by a separate motor.
  • the region of the drum equipped with these extends at least over 60% of the drum length or over the entire drum length, and that the inside diameter of one or more baffle rings (s) each with a removable, overlapping ring can be assembled from elastic material.
  • the rings made of elastic material are essentially rubber rings, although other elastomers can also be selected on a case-by-case basis, depending on the material to be emptied.
  • the elastic rings help to protect the goods or vice versa to protect the storage rings, depending on the physical properties of the goods to be discharged from the screening drum.
  • a plurality of driver hooks distributed on the inner circumference and generally arranged in a row and inclined in the outlet direction are arranged in the drum, the driver hooks preferably being angled in their central region by approximately 10 ° and their tips are aligned almost concentrically to the base of the drum.
  • the proposed arrangement and design of the catch hook thus ensures a repeatedly repeated safe grasping and lifting of the sack strips and their turning during their passage through the sieve drum and thus their optimal emptying before their task into the discharge chute provided for them.
  • the feed housing be designed in its outlet area as an input guide which opens into the sieve drum and can be locked in its end region by a pendulum apron.
  • a pair of rollers arranged in front of the guide chute for the sack guide and dividing the material content is provided, the rollers of which can be driven separately, at least the peripheral speed of a roller being adjustable so that the rollers are at a distance from one another in parallel by at least one displaceable arrangement of a roller are variably adjustable, and that the actuators for the position-changeable fixing in the event of an overload release an additional load-dependent buffer path.
  • a significantly improved disintegration of the agglomerated material is achieved by setting different circumferential speeds of the rollers and the associated "grinding" of the material, whereby the possibility of premature tearing of the bag sets limits when setting differential speeds.
  • Actuators that enable the roller spacing to be set secure the rollers, their arrangement and their drives from being destroyed by the buffer path that becomes effective in the event of an overload.
  • the separate drive of the rollers is carried out by a motor or a gearbox with corresponding drives and that at least one drive is assigned a gear member that can change the speed.
  • a slide is provided as a support for the roller, which can be displaced parallel to the axis, which is movably arranged between two legs of a U-shaped support frame by actuators actuated by pressure medium, and that in the region of the connecting web of the two parallel leg planes of the Support frame, fixed in position, the second roller is arranged.
  • driver elements are round bars, which are offset by 180 ° in some cases, arranged in the direction of rotation inclined blow bars.
  • a modification of the device dispenses with the flat oversize separating sieve which is generally customary in these devices.
  • This amendment provides that a cylindrical sieve with a smaller mesh size is arranged concentrically at a distance from the inner sieve drum around the sieve drum, the sieve being transferred, at least on the outlet side, into a closed length range as a discharge zone with an axially parallel outlet for the oversize grain.
  • the outer sieve be assembled from a plurality of individually exchangeable sieve fields which form circular sections in their cross-section and are supported by a support structure.
  • the sacks to be emptied are fed into the sack cutting area 1 'by the conveyor 1.

  • the load-dependent inclination of the bottom 51 is determined by at least one resilient element, which in the case of this example is designed as a gas pressure spring 53, the spring characteristic being set such that, with a lower weight of the sack, e.g. B. by a damage-induced partial emptying, the sack so far that practically the same depth of penetration by the knife arranged above and below 2 is given.
  • the sack is roughly divided into thirds when sliced open, depending on the distance mentioned.
  • a part of the originally sacked goods directly hits the input guide 7 forming part of the feed housing 3, while the rest of the goods remaining in the sack parts or mixed with them are fed into the screening drum 8.
  • a slightly overlapping and automatically returning pendulum apron 9 is provided in the outlet area of the input guide 7.
  • the empty sack material including the remaining or adhering material in the sieve drum 8 is subjected to a lively movement in the sieve drum 8 by means described later and is thereby cleaned of the material, the drum being designed so that the emptied, cleaned sack material is over the empty bag chute 15 opens into the empty bag outlet 15 '.

  • the retaining rings 12 have the purpose of preventing the goods from being shot through and of the bag material passing quickly through the sieve drum 8, so that the main discharge of the goods to be separated takes place in the front region of the drum and in the rear, ie. H. An intensive residual emptying takes place in the end area.
  • the screening drum 8 there are multiple, distributed on the inner circumference, arranged in rows, inclined obliquely in the discharge direction catch hooks 11 which grip the bag parts, lift them up and let them fall back onto the drum base.
