Definitions
- the present invention relates to a method according to the pre-characterising clause of claim 1.
- the present invention also relates to an arrangement according to the pre-characterising clause of claim 3.
- Sorting at source therefore generates various fractions, which are often transported together to a sorting plant for sorting in a waste sorting arrangement. It is important, in the case of a waste sorting arrangement, that this has the capacity to separate and sort out the various types of fractions sorted at source, and that this sorting is performed with as few errors as possible. It is also advantageous if such a waste sorting arrangement is designed so that it can be readily expanded to include more types of waste fractions.
- An arrangement for sorting sacks is already disclosed, for example, by SE 9401754-8.
- This document discloses an arrangement for sorting differently coloured waste sacks, which occur in random distributions and contain different types of waste sorted at source.
- This arrangement comprises sorting stations, which by means of a colour analysis described in SE 9500165-7 identify and then separate waste sacks of a predetermined colour, which are conveyed on a conveyor belt.
- the arrangement does not comprise any control mechanism after sorting to ensure that separation has been performed correctly, that is to say that only waste sacks of the predetermined colour have been sorted out.
- the object of the present invention is to provide greater sorting accuracy in the sorting of waste sacks. This is achieved by a method which has the characteristics specified in the characterising part of claim 1. An arrangement for performing the method has the characteristics specified in the characterising part of claim 3.
- 1 denotes a load hopper intended for unsorted waste sacks, the hopper being connected to a slatted conveyor 2 for conveying waste sacks to a distributing conveyor 3.
- 4 denotes an acceleration bar, which receives waste sacks from the distributing conveyor 3 and is designed to separate the waste sacks from one another so that they are placed on a first conveyor belt 5 at a certain interval from one another.
- a first sorting arrangement 6 is arranged along the first conveyor belt 5 and is designed to sort out waste sacks of a predetermined colour.
- Waste sacks of different colours contain different types of refuse sorted at source and in the load hopper 1 the differently coloured waste sacks occur in random distributions.
- the waste sacks must be placed on the first conveyor belt 5, which conveys the waste sacks for sorting in the first sorting arrangement 6.
- the waste sacks must be placed on the first conveyor 5 in such a way that two sacks do not end up alongside one another or on top of one another.
- the waste sacks from the load hopper 1 are conveyed to the distributing conveyor by the slatted conveyor 2.
- the distributing conveyor 3 distributes the waste sacks to the acceleration bar 2, which must ensure that two sacks do not lie too close or on top of on another on the first conveyor belt 5.
- the waste sacks should be spaced at an interval of at least 0.5 m from one another on the first conveyor belt 5.
- the sorting arrangement 6 uses sensors to detect when waste sacks of a predetermined colour on the first conveyor belt 5 reach and pass a certain position in the first sorting arrangement 6, and then actuates elements for removing the sack from the first conveyor belt 5. In this sorting, however, it may happen that a waste sack of a colour other than the predetermined colour is removed from the first conveyor belt 5. This occurs, despite the use of the acceleration bar 4, due to the fact that sacks lie too close to one another, so that a sack with a colour other than the predetermined colour is caught up with a sack of the predetermined colour when the later is separated out.
- a second conveyor belt 7 is arranged beneath the first sorting arrangement 6 and a second sorting arrangement 8 is arranged along the second conveyor belt 7.
- 9 denotes a third conveyor belt, which is arranged beneath the second sorting arrangement 8 and is connected to the load hopper 1.
- the second conveyor belt 7 is designed to receive all sacks separated out by the first sorting arrangement 6 and to convey these to the second sorting arrangement 8, which is designed to enhance the sorting accuracy by sorting waste sacks of different colours.
- the second sorting arrangement 8 functions in a manner known in the art and is designed to identify and separate the sacks incorrectly sorted out by the sorting arrangement 6, that is to say to separate the sacks on the second conveyor belt that are of a colour other than the predetermined colour, to which the first sorting arrangement is sensitive.
- the second sorting arrangement 8 must therefore be sensitive to all colours other than the colour to which the first sorting arrangement 6 is sensitive.
- the sacks sorted out by the second sorting arrangement 8 are received by the third conveyor belt 9, which conveys the sacks incorrectly sorted out by the first sorting arrangement 6 back to the load hopper 1.
- the returned sacks can then be conveyed to the first sorting arrangement 6 again for renewed sorting.
- an arrangement according to the invention may comprise more than one first conveyor belt 5, which increases the sorting capacity, and more than one first sorting arrangement 6, which increases the number of different types of waste that can be sorted out.
- the embodiment shown in Figure 1 comprises two parallel first conveyor belts 5 and two first sorting arrangements 6 and 6' along each of the first conveyor belts 5.
- the sorting along the two conveyor belts 5 is preferably structured identically, that is to say the two first sorting arrangements 6 are both sensitive to the same predetermined colour and the two first sorting arrangements 6' are both sensitive to the same predetermined colour.
- Running under the two first sorting arrangements 6 is a second conveyor belt 7, which receives sacks moved from the two first conveyor belts 5.
- a second conveyor belt 7 similarly runs beneath both of the first sorting arrangements 6'.
- a second sorting arrangement 8 and 8' respectively is designed to sort out the sacks incorrectly sorted out from the first sorting arrangements 6 and 6' and to increase the sorting accuracy.
