Definitions
- the present invention relates to a method and an arrangement for the sorting of refuse sacks according to the pre-characterising clause of claim 1 and claim 4 respectively.
- SE 507257 discloses a method of the aforementioned type. According to the method each refuse sack is assigned a predetermined means of identification, such as colour coding, for each refuse fraction, by means of which sacks are sorted. The refuse sacks are transported along a conveyor and are sorted by successively identifying and separating each refuse sack having a predetermined means of identification.
- SE 517 667 discloses a method of sorting for identifying sacks having a means of identification, but in contrast to the aforementioned method it is refuse sacks not having a predetermined means of identification that are separated out. In the sorting of refuse sacks provided with means of identification, there is a general desire to achieve a greater number of unadulterated fractions of refuse sacks, low energy consumption and low costs.
- the object of the present invention is to provide a method that is improved in the aforementioned respects.
- a further object of the invention is to provide an arrangement for performing the method according to the invention. This is achieved by an arrangement having the characteristics specified in claim 4.
- the invention affords lower sorting-related costs and lower energy consumption. Furthermore, the sorting can be performed with few errors, which is important in obtaining unadulterated fractions, which is in turn important for processable fractions, as in the manufacture of biogas, composts and in other material recycling.
- Fig. 1 in a schematic plan view from above shows an example of an arrangement for carrying out the sorting of two selected fractions of refuse sacks according to a known method
- Fig. 2 similarly shows an example of an arrangement for carrying out sortings of two selected fractions of refuse sacks according to the present invention with the same degree of adulteration of the residual fraction and essentially the same capacity.
- Figs. 3 and 4 show two comparative examples of the sorting of five selected fractions of refuse sacks according to a known method and according to the present invention, it being possible here also to carry out the sorting with the same degree of adulteration of the residual fraction and essentially the same capacity.
- the sacks provided with red (R) colour coding are identified and separated at the first three sorting stations 4a-6a, 4b-6b, 4c-6c and thereafter the sacks provided with green (G) colour coding are identified and separated at the three succeeding sorting stations 7a-9a, 7b-9b, 7c-9c.
- R red
- G green
- Separating sacks identifiable by the same colour at multiple succeeding sorting stations in this way naturally increases the capacity but primarily improves the unadulterated nature of the unseparated residual fraction, that is to say the sacks which have not been identified at any earlier sorting station.
- the sacks provided with red (R), green (G), blue (B) orange (O) and grey (GR) colour coding are identified and separated in such a way that on each sorting conveyor 3a-3c the sacks provided with red (R) colour coding are separated from the other sacks at the first two sorting stations 4a-4c, 5a-5c, and sacks provided with green (G) colour coding are then separated at the two succeeding sorting stations 7a-7c, 8a-8c.
- Refuse sacks with blue (B), orange (O) or grey (GR) colour coding are identified and separated at the three succeeding sorting stations 1 la-11-c, 12a- 12c, 13a-13c. In this example, therefore, 21 sorting stations are needed.
- a sorting according to the invention of five differently colour-coded, randomly distributed refuse sacks the refuse sacks are placed and transported as illustrated in Fig. 4.
- the first four sorting stations 4a-4c, 5a-5c, 7a-7c, 8a-8c produce a separation of sacks provided with red (R) and green (G) colour coding.
- a final sorting station (14a-14c) for each conveyor 3a-3c sacks provided with blue (B), orange (O) or grey (GR) colour coding are simultaneously identified and separated onto yet another sorting conveyor 15.
- sacks provided with blue (B), orange (O) or grey (GR) colour coding are identified and separated onto yet another sorting conveyor 15.
- three successively arranged sorting stations 16, 17, 18 in which sacks provided with blue (B), orange (O) or grey (GR) colour coding are identified and separated.
- the degree of adulteration achieved corresponds to that obtained in the example of the prior art, but is achieved with a smaller number of sorting stations, that is, in this example, 18 stations.
