Definitions

  • the invention concerns a sorting device in accordance with the preamble of claim 1.
  • a sorting device in accordance with the preamble of claim 1.
  • Such a device is known from EP 1785200 .
  • the disadvantage of the known device is that the sorting belt has ridges that makes the belt fairly thick so that it is difficult to fold and guide the belt around the rollers due to the required deformations of the belt, which deformations also lead to undesired wear of the belt.
  • the sorting device is according to claim 1.
  • a simple and thin sorting belt is used to move the sorting tines in and out of the drum so that the sorting tines pick up cardboard pieces from the sorting belt.
  • the invention further concerns an embodiment according to claim 2. This improves the sorting of cardboard pieces from a mixed flow of material.
  • the invention further concerns an embodiment according to claim 3. This makes the sorting device more flexible in handling mixtures of different thickness on the sorting belt.
  • the invention further concerns an embodiment according to claim 4. This improves the removing of the cardboard pieces from the sorting tines as the second drum pushes the cardboard piece in axial direction off the sorting tine.
  • the sorting device 1 as shown in figures 1 and 2 comprises a frame 25 having two sidewalls 14 between which a sorting belt 13 can move in a direction of conveyance 32.
  • the sorting belt 13 runs over a drive pulley 20 and a return pulley 20A and is guided by support rollers 21 between the sidewalls 14 and held taut by the return pulley 20A.
  • a drive 22 drives the sorting belt 13.
  • a supply belt 2 supplies a mixture of paper sheets and cardboard pieces 36 (see figure 2 ) to be sorted to the sorting device 1.
  • the speeds of the supply belt 2 and the sorting belt 13 are selected in such a way that the supply belt 2 deposits most individual paper sheets and cardboard pieces 36 one after the other in a single layer on the sorting belt 13.
  • Document EP 1785200 gives a more detailed description of a similar device and the skilled man can think of many variations of the design of the sorting belt 13 and/or the sorting device 1.
  • sorting tines 3 extend from the outside surface of an inner drum 6 that rotates with an outer drum 5 in a direction of rotation 27.
  • Support rollers 16 support the outer drum 5 and let the outer drum 5 rotate around a top axis of rotation 7.
  • the sorting tines 3 extend from the outside of the inner drum 6 to a maximum radius R from a bottom axis of rotation 8 that is the centre of the inner drum 6 and that is located below the top axis of rotation 7.
  • the sorting belt 13 is supported by a support plate 15 that is resiliently supported by springs 23 that are connected by a bracket 24 to the side walls 14.
  • the support plate 15 supports the sorting belt 13 so that the paper sheets, cardboard pieces 36 and/or the sorting belt 13 will press against the sorting tines 3 and force these to retract in the inner drum 6 over a distance X against the pressure of a spring 31.
  • the spring 31 presses against the sorting tines 3 so that they extend outside the inner drum 6 to the maximum radius R when the sorting belt 13 does not push against them and forces them to retract.
  • the spring 31 is mounted in a holder 30 fixed against the inner surface of the inner drum 6, for instance by welding.
  • the rotation speed of the inner drum 6 and the speed of the sorting belt 13 are synchronized so that the tip of the sorting tines 3 at the radius when the distance X of the retraction has its maximum value, which means the narrowest part of the gap between the inner drum 6 and the sorting belt 13, is approximately equal to the speed of the sorting belt 13.
  • the sorting tines 3 lift cardboard pieces 36 off the sorting belt 13 and deposit the cardboard pieces 36 on a first discharge belt 9 and the paper sheets remain lying on the sorting belt 13 and are conveyed to a second discharge belt 12.
  • guide plates 11 are provided in order to prevent the paper sheets from falling onto the ground.
  • the second discharge belt 12 conveys the paper sheets to a storage place and/or a place where the paper is processed further.
  • cardboard pieces 36 include corrugated cardboard and those types of paper that have increased resistance against tearing, which might include books or a bundle of paper sheets.
  • the inner drum 6, on which the sorting tines 3 are fixed has a smaller diameter than the outer drum 5 rotating with said inner drum 6 and the outer drum 5 has apertures 35 through which the sorting tines 3 project. This causes that at increasing distance from the bottom area of the inner drum 6 the sorting tines 3, while they are at their maximum radius R from the bottom axis of rotation 8, will project increasingly less far outside the outer drum 5 so that the outer drum 5 pushes the cardboard pieces 36 off the sorting tines 3. As a result, the cardboard pieces 36 fall off the sorting tines 3 onto the first discharge belt 9 placed beside the outer drum 5 for that purpose.
  • a guide plate 10 guides the falling pieces of cardboard.
  • the first discharge belt 9 transports the cardboard pieces 36 to a location where they are further processed.
  • Support rollers 16 are provided on the outside of the sidewalls 14 on the frame 25. On these support rollers 16 the outer drum 5 can rotate about a top axis of rotation 7 which is preferably more or less perpendicular to the direction of conveyance 32 of the sorting belt 13.
  • the outer drum 5 is completely open on the inside and has a guide edge 4, as a result of which the outer drum 5 always stays more or less in the same position above the sorting belt 13.
  • the inner drum 6 rests on the bottom part of the outer drum 5, which inner drum 6 rotates with the outer drum 5 around the bottom axis of rotation 8.
  • pressure rollers 17 are provided at the position of the support rollers 16, each pressure roller 17 being fixed by means of springs 18 on a support 19.
  • the springs 18 make some movement of the inner drum 6 and/or the outer drum 5 possible.
  • a support plate 15 supports the sorting belt 13
  • springs 23 mounted upon a support 24 and fixed on the frame 25 resiliently support the support plate 15. Because of the spring-loaded support plate 15 and also because of the possibility of movement of the inner drum 6, the material on the belt conveyor 13 can have a changing thickness without causing any problem.
  • the tip 37 of the sorting tine 3 penetrates the cardboard piece 36 until the tip 37 pushes against the sorting belt 13.
  • the sorting belt 13 then pushes the sorting tine 3 the distance X into the holder 30 against the force of the spring 31.
  • the tip 37 is part of the first sorting tine 3 to penetrate a cardboard piece 36, which means that it is near the front 38 of the cardboard piece 36, the cardboard piece 36 will get the same speed as the tip 37 and slide over the sorting belt 13.
  • Figure 2d shows the situation where the sorting tine 3 has moved further away from the gap and protrudes its maximum length outside the outer drum 5.
  • the distance X is zero.
  • the cardboard piece 36 pulls against the tip 37.
  • the shape of the tip 37 is such that the direction of pulling keeps the cardboard piece 36 fixed on the tip 37 and especially keeps the raised edge 40 fixed against the tip 37.
  • the tip 37 can be partly cylindrical and/or can have a groove 41 as shown in both embodiments of figure 3.
  • the tip 37 of the sorting tine 3 now lifts the front 38 of the cardboard piece 36 from the sorting belt 13 and the rest of the cardboard piece 36 follows. As shown in figure 1 the sorting tines 3 lift the cardboard piece 36 to above the belt 9 and there the outer drum 5 pushes the cardboard piece 36 off the tip 37.
  • the tip 37 pushes against a paper sheet on the sorting belt 13 the tip 37 might create a hole in the paper sheet, but the tip 37 will not get a grip on the paper sheet as the tip 37 will tear the hole in the paper sheet and there will be no raised edge 40 that can hold the paper sheet on the tip 37 of sorting tine 3.
  • the tip 37 will leave paper or other easily tearing material on the sorting belt 13 but it will lift in the way described earlier the difficult tearing cardboard pieces 36 off the sorting belt 13.
  • the cardboard piece 36 can be pushed in other ways form the tip 37, for instance using a comb in case there is no outer drum 5.
  • the inner drum 6 has a central axis that is mounted with spreaders in the inner drum 6 and has bearings in which it rotates. These bearings are so that they make vertical movement of the inner drum 6 possible, so that thick stacks of cardboard pieces 36 can move between the inner drum 6 and the sorting belt 13.
