Definitions

  • the invention relates to an unloading and separating device for sacks from a feed container fed by means of a pallet lifting device or similar lifting elements through disordered piles to an integrated or assigned bag cutting and emptying machine.
  • DE-GM 83 22 350.9 has disclosed a bag separation device for dissolving a pile formed from individual containers into an orderly, rectified and approximately equally spaced sack sequence.
  • This document provides for the unordered bag feeding in a reactor equipped in the conveying direction with Bodenhubtisch hopper before, the gradually the bags in the height of an A bquekante zoom leads, from which it is lifted by a correspondingly arranged on this excavation roller and arranged on a plurality of rising behind the other belt conveyor, the bandwidth of the corresponds to twice the length of the bag.
  • a further belt conveyor which only has a useful width corresponding to the sack width, and which is delimited in the transfer area by a trough wall, is assigned to these conveyors at right angles to the sack length, so that the sacks are pulled off the leading end conveyor and thereby rectified,
  • the lifting floor After the lifting floor has been emptied, it must first be brought into its lower starting position in order to be able to initiate a subsequent loading by the forklift.
  • the disadvantage is the need to equip the feed container with a lifting table leading upwards at irregular intervals, which must be moved to a new delivery height when the discharge edge of the container is not occupied, controlled by a mechanical or optical scanning device.
  • the excavation roller has continuous excavation elements which extend over its length, so that, as a rule, at least two bags are placed on the subsequent belt combination without any loss in distance between the bags
  • the system is not suitable for dissolving a disorganized pile.
  • Depalletizing systems of the type described there enable the individual containers to be dispensed at any controllable subsequent intervals from the layer layer of the pallet to be emptied and, if the layer has been cleared, the individual containers of the subsequent layer layer placed in the dispensing position can be quickly fixed in place.
  • the pallet is placed in a tilting device equipped with a lifting floor.
  • the timing of the delivery and the change in the height of the lifting floor can be controlled by a program control.
  • the conveying members and a bag lifting roller known per se which can be emitted to the bag cutting device, are designed and arranged for the multi-row feeding of bags into the bag cutting and emptying machine, that here the distance of the bag sequence of each row in an approximately by the radian of the circumferential pitch of the lifting bars offset by a pitch angle and the course of the approximately parallel series formation can be determined by the longitudinal division of the lifting bars arranged in sections on the circumference of the bag lifting roller, and the position of the bags in relation to the transport direction - in some cases relative to this - can be different, and that the circular knife of the bag cutting device can be divided into four pairs coaxially aligned, separately drivable shafts are each arranged in a predetermined number in the axial direction so that each sack - regardless of its orientation - can be cut several times and via a transfer chute to separate the empty sack material from the bulk material and the oversize part of a sieve drum known per se with an outlet collecting box and Vi
  • the multi-row design of the bag cutting device for the occasional simultaneous cutting of several bags enables a substantial increase in throughput
  • the multi-section conveyor section - as the first link - having a scraper conveyor with intermediate floor provided with lifting elements, and the like Scraper conveyor virtually forms the bottom of the feed container which remains stationary in its position.
  • the parallel row formation is determined by the longitudinal division of the lifting bars arranged in sections on the bag lifting roller, axially parallel, and the spacing of the bag sequence of each row in a given by the radians of the circumferential pitch of the lifting bars offset by a pitch angle.
  • the conveyor section has an ascending scraper conveyor provided with lifting elements, which is equipped with an intermediate floor arranged between the upper and lower run, which forms the support for the circumferential lifting elements, and that in the discharge area of the scraper conveyor a sacking roller directed towards the bag inclined runway is arranged.
  • the scraper conveyor is designed as a chain push conveyor, the lifting elements being made of profiled hardwood and sliding over the intermediate floor.
  • the different materials for the mezzanine which usually has a metallic base and the hardwood lift bars, reduce friction losses.
  • a light barrier is arranged as a control element in the transfer area of the sacks to the sack lifting roller so that when the radiation path is interrupted by the sack lifting roller loaded with bags, the scraper conveyor drive stops for as long until the bag lifting roller is free for a new assignment for further delivery.
  • a sliding plate for guiding the bulk material which has escaped from damaged bags is designed to open into the upper outlet area of the screening drum on the task-side rear wall of the task container.
  • the sieve drum is mounted in an at least partially constructed as a drum housing, wherein the support frame is connected to the main frame of the machine frame, and that the two inlet and outlet-side limitations of the drum housing are further components of the feed container and the discharge chute for the empty bag material including the entire housing.
  • the sack cutting device is connected with its transfer chute to the overall housing, so that the overall machine is one unit.
  • a longitudinal wall of the entire housing leading into the feed container is inclined over a partial length to the scraper conveyor, and that one for receiving a dust filter on the opposite longitudinal wall of the entire housing funnel-shaped extension is provided.
  • the inclined design of a longitudinal wall of the entire housing facilitates the transfer and detection of the individual bags by the scraper conveyor.
  • the funnel-shaped extension formed on the opposite longitudinal wall is only necessary if a separate dedusting filter is arranged,
  • the device can be connected to a central aspirate and the return of the separated material to the device does not appear to be necessary, the intended funnel-shaped expansion of the housing is unnecessary.
  • a simplifying modification of the device for fabric bags provides that the function of the excavation roller is taken over by drivers on the lifting bars of the scraper conveyor, which are arranged laterally offset from bar to bar.
  • the feed container 5 to be unloaded by an unloading and separating device 10 from the sacks 11 introduced as a disorganized pile is formed downwards, virtually forming the bottom, by means of a lifting device 13 and intermediate bottom 14, which enables the juxtaposition of several sacks 11 over its width.
  • the lifting elements 13 can be formed from profiled hardwood.
  • the chain pusher conveyor 12.1 leads to a discharge path 15 arranged in its delivery area, which is either designed as a chute - or, as shown here as a roller conveyor 15.1 - to a sack lifting roller 16, which in turn feeds the sacks 11 in multiple rows to the sack cutting device 17 connected to the feed container 5.
  • a light barrier 18.1 arranged in the transfer area 12.2 of the chain pusher conveyor 12.1 to the roller conveyor 15.1 gives an impulse for stopping the drive of the chain pusher conveyor 12.1, this being maintained until the bag excavating roller 16 for further occupancy with bags 11 is free.
  • a slide plate 5.3 leads from the rear wall 5.2 on the task side to guide the bulk material 11.2 emerging from damaged bags 11 into the upper outlet region of the sieve drum 21.
  • bag lifting roller 16 it should be noted in detail that these are divided over their length and circumference into three sections 16.2, each offset by 120 °, by means of the lifting bars 16.1, so that the bags 11 can be placed at least in a partially offset sequence of the connected bag cutting device 17 .
  • a dust escaping inhibitory skirt 12.3 is provided between the blind lifting roller 16 and the release area of 12.2 Kettenschubfö l dercrs 12.1 .
  • this provides the arrangement of two axially spaced 18 in the sack 11 reduced by the average incision depth, paired, each diametrically driven and equipped with two circular knives 19 knife combinations 19.1, the distance 20.1 of the coaxial aligned shafts 20 arranged circular knife 19 to each other is selected so that - regardless of the direction of the bag 11 - in practice each sack 11 is cut at least twice.
  • a resilient pad 17.2 compensates at least for the reduced thickness of the bag 11 to the extent that at least the upper circular knives 19 open the bag 11 sufficiently for further emptying into the sieve drum 21.
  • the bag cutting device 17 is designed in its lower region as a transfer chute 17.1 into the sieve drum 21.
  • the sieve drum 21 is supported in an at least partially designed as a drum housing 2 support frame 2.1, which in turn is connected to the main frame 1 of the machine frame.
  • the inlet and outlet-side boundaries 3/4 of this housing 2, which is ultimately part of a, the. Task container 5 including the entire housing 6, is a geared motor 22 on the inlet side as a drive motor for the sieve drum 21, and the bearing 23, each by a shaft 24 connected drum drive or support rollers 25, with corresponding bearings 23.1 being assigned to the outlet-side boundary 4 of the drum housing 2.
  • the discharge chute 7 for the empty sack material 11.1 is connected to the drum housing 2 - and also as a component of the overall housing 6.
  • the bulk material 11.2 emerging from the sieve drum 21 is connected via an outlet collecting box 21.1 to a resiliently suspended vibrating screen 21.2 equipped with vibrator 21.3, the outlet collecting box 21.1 and the vibrating screen 21.2 being sealed from one another by a resilient bellows 21.4.
  • the oversize particles 11.3 separated by the vibrating sieve 21.2 which generally has a mesh size of 10 mm, or the coarser impurities, are removed by a separate discharge 21.5, while the actual sieve bottom of the vibrating sieve 21.2 via a chute 21.6 and an outlet 21.7 Bulk material 11.2 leads to further processing.
  • Positions 21.5 and 21.7 are each provided with a movable sleeve 21.8 and 21.9.
  • the bags 11 are laterally fed into the feed container 5 via its inclined wall 5.2, while a funnel-shaped extension 8 of the entire housing 6 is provided on the opposite side for receiving a dedusting filter 26.
  • the dedusting filter 26 is only required if the product dust is to be returned to the main material flow. In the case of dedusting by central aspiration, only the lateral arrangement of a dust extraction connection 27 on the overall housing 6 is necessary.
