DESCRIPTION:
BRIEF SUMMARY
The invention deals with an identification unit for garbage cans, which can be emptied by means of emptying devices or so-called dumping or tipping into collection vehicles as well as being weighable for determination of the weight of the garbage contained therein respectively before and after the emptying process upon the emptying device or dumping arrangement, wherein the garbage can carries a coded sensor, which can be put into communication with an identification system assigned to the emptying device or the dump on board the collection vehicle.
Methods and devices for determining the weight of garbage, especially household- and industrial garbage have already been proposed for garbage disposal, which not only enable an accurate weight-wise determination of the garbage contained in the respective garbage can but which also permit to assign the garbage quantities concerned to the respective originator and then to assure garbage disposal fee calculation referred to weight.
While namely flat garbage disposal fees do not encourage citizens and plants to reduce the amounts of garbage, a calculation of the garbage disposal fee as a function of weight can have a salutary effect upon the reduction of the generated volumes of garbage.
In particular this method encourages the originator to perform a classification of the generated garbage in such a way, that a separate collection of biological garbage, recycleable garbage and garbage to be dumped on a waste stockpile is performed. If then the fee calculation for the different types of garbage are based on appropriately different fee units, then the actual garbage disposal can be optimized through the garbage disposal fee generated.
A precondition for the smooth handling of garbage disposal in this case is however, that each individual garbage can be equipped with an identification unit, which not only assures a correct assignment to the respective originator, rather in addition also assures that only those garbage cans are always emptied into the collection vehicle, which also comprise the code for the respective type of garbage.
In any case it is of decisive importance, that the identification unit on the garbage can contain an instruction which not only assures smooth communication with the identification system on board of the collection vehicle, rather is also simultaneously rugged in continuous use.
The invention achieves this target definition mainly in that the code sensor is housed in a receptacle of the stiffening collar or dumping engagement grip or part at the garbage can and/or is enclosed on all sides.
The stiffening collar or the dumping engagement grip is an element of the garbage cans necessary for their functioning, because they come into interaction with the emptying devices on board of or dumping arrangements in the collection vehicle. For this purpose stiffening collars or dumping engagement parts or grips are laid out in a rugged and dimensionally stable manner and can therefore be utilized as a permanently secure housing for the code sensor.
Herein it has proved itself, if in the invention the coding sensor is housed in the receptacle so as to be protected from shocks, for instance cushioned or floating or suspended with spacing on all sides from the enclosing walls.
It has also proved itself if the receptacle consists of a pot- or tub-shaped depression molded into the stiffening collar or the dumping engagement part, which is closable by a lid. The receptacle can be molded in this manner simply indeed within or in between the ribbing of the stiffening collar or dumping engagement part in the injection molding die of the garbage can.
The lid serving for closure of the receptacle after insertion of the coding sensor can be fixed at the stiffening collar or the dumping engagement part by welding, bonding, bolting or riveting; and this independently of the circumstance whether the opening of the pot- or tub-shaped molding and with this the lid covering same is located at the bottom side, the top side or at the peripheral side of the stiffening
