Definitions

  • the present invention relates to an opening apparatus for a waste container.
  • containers for waste bags comprising opening apparatuses which pass from a closing position to an opening position by means of a pedal connected to leverage systems. Pressing the pedal, the opening apparatus passes from the closing position to the opening position in which a user can throw a waste bag inside a chamber of the container through an opening of the opening apparatus.
  • containers comprising opening apparatuses mounted with containers and comprising a prehensile lever to be raised by hand to open an inlet opening towards the chamber of the container.
  • EP0893368A1 discloses an opening apparatus for waste bags comprising an opening shell that pass from an open to a close position and an opening apparatus of a waste container with a drawer of cylindrical shape and a tilting wall, that opens towards the container when the drawer is closed, to enlarge the dropping opening, wherein the tilting wall is connected to the drawer and operated by a bar, connected to a second bar, that rotates with the drawer.
  • the opening apparatus during a passage between a closing position to an opening position leaves an opening in the chamber of the container open, allowing the wrong insertion of waste bags.
  • the insertion of waste bags through the opening of the opening apparatus causes the bags to fall one on top of the other creating a pyramid of bags.
  • the pyramid-arranged bags do not homogeneously fill the chamber of the container, preventing the use of all the space available in the chamber.
  • the pyramid of bags can come into conflict with opening and closing mechanisms of the opening apparatus, leaving the container jammed in an intermediate position, or jammed in the opening or closing position.
  • the opening and closing mechanisms of the container are energy-inefficient and consume electric batteries in a short time.
  • the object of the present invention is to provide an opening apparatus separably mountable with a waste container which overcomes the disadvantages set forth above and which functions without jamming, which is solid, safe and which allows predetermining a defined volume of waste to be thrown through it preventing the delivery of higher volumes of waste than allowed, which in the closing position has no access openings, nor even partial, which allows passing from a closing position to an opening position without any contact with parts of the human body and only if there is an identification of a user authorized to throw waste bags, which is energy efficient, which consumes little electric battery, which cooperates with the elements of the opening apparatus according to claim 1.
  • this object is achieved with an opening apparatus separably mountable with a waste container according to claim 1.

  • the lid 102 can also comprise only an openable flap 111, 112.
  • the container 100 comprises an opening apparatus 10 which is separably mountable with the container 100 and is adapted to pass from a closing position which does not provides any access openings to the containment chamber 103 to an opening position which provides at least an access opening to the containment chamber 103.
  • the opening apparatus 10 is separably mountable with at least one of the two side flaps 111, 112 of the lid 102 of the box-like body 101 of the container 100.

If the tilting wall 70 were not there, the waste bag would first fall into the chamber 103 without acquiring sufficient kinetic energy to be pushed towards the walls of the containment chamber 103.
  • the thrust given to the waste bag by the tilting wall 70 advantageously allows preventing the opening apparatus 10 from being jammed, that no pyramid of waste is formed under the drop point of the waste bag, that the containment chamber 103 for waste of the container 100 is filled homogeneously and as effectively as possible.
  • the lack of the tilting wall 70 would cause the waste bag to fall by gravity immediately under the predefined chamber 35 for housing waste forming a pyramid of waste bags.

  • the guide element 20 stops its rotation motion when an upper portion 22 of the guide element 20 abuts against a stop element 122 of the cap 12 of the coupling body 11.
  • the stop 122 removes a degree of freedom when the tilting wall 70 is in the closing position otherwise the friction on the guide element 20 could cause the tilting wall 70 to rub on the drawer 30, which the curvilinear shape of the guide slot 26 advantageously avoids, advantageously preserving the elements of the opening apparatus 10 for a longer time.
  • the second elastic recall element 52 avoids vibrations and favours the sliding of the drawer 30 and of the pin 36 inside the guide slot 26.

  • the cam 204 pushes the bracket 202 in such a way as to pass the bracket 202 from the engagement position with the first tooth 221 to the multiplicity of engagement positions between the first tooth 221 and the second tooth 222 of the toothed flange 201 as shown in figure 12 .
  • the motor 205 continues to rotate the cam 204 until the bracket 202 passes to the disengaged position from the toothed flange 201 as shown in figures 13 and 14 .
  • the toothed flange 201 is free to rotate and causes the drawer 30 to rotate in the angular opening position and the opening apparatus 10 in the opening position.
  • the cam 204 pushes the switch 206 causing the motor 205 to switch off.
  • the third elastic element 224 is in the tension position.
  • the pedal 80 is lowered by pulling the pulling cable 81 and passing the opening apparatus 10 from the opening position to the closing position.
  • the closing position of the opening apparatus 10 corresponds to the engagement position of the bracket with the first tooth 221 of the toothed flange 201.
  • the control unit is mounted inside a metal box 300 of the opening apparatus 10.
  • the control unit comprises at least one memory and a processor adapted to control at least the motor 205.
  • the metal box 300 mounts five antennas electrically connected to the control unit which is in communication with a control unit or with vehicles or with other control units of other containers.
  • the control unit advantageously allows preventing the five antennas from interfering with each other and with other radio communication systems.
  • the five antennas can allow LTE, 3G, 4G, LoRaWAN, WI-FI, radio, RFID tag readers, GPS communication.
  • the control unit is adapted to read the position of the drawer 30 by means of the magnetic elements of the toothed flange 201 or other angular position sensors.
  • the opening apparatus 10 also comprises a position detector, for example a GPS, for communicating the position of the container 100.
  • a position detector for example a GPS
  • control unit It is possible to communicate with the control unit to transmit information or receive information to and from the container 100 by programming the control unit remotely or closely. For example, from the remote operating centre it is possible to control all the control units of the opening apparatuses 10 by commanding to remain in the opening position or to remain in the closing position.
  • the lever 45, the first elastic recall element 51, the lock 200 and the leverage system 85 with pedal 80 cooperate synergistically with the tilting wall 70 with the spacing bar 90 and the guide element 20 of the opening apparatus 10 so as to make the push movement of the waste bag more effective and efficient by avoiding the creation of a pyramid of waste and that the opening apparatus 10 works without jamming, which is solid, safe and that allows predetermining a defined volume of waste to be thrown through it, preventing deliveries of volumes of waste higher than allowed, which allows passing from the closing position to an opening position without any contact with parts of the human body and only if there is an identification of a user enabled to throw waste bags, which is energy efficient, who consumes little electric battery.
  • the opening apparatus 10 allows achieving the requirements and objectives required by the current Emilia Romagna Regional Law relating to the Punctual Fee, the so-called TCP.
  • the TCP aims at monitoring the number of deliveries of each user, in this case limited to a maximum of 30 litres of volume for each delivery, in order to be able to apply a tax proportional to the actual annual uses of the deliverer.
  • an alternative guide element 20 comprises a second slot 28 on the upper portion 22 of the guide element 20.
  • the drawer 30 comprises a further pin 37 adapted to engage inside the second slot 28 of the guide element 20.
  • the further pin 37 enters the second slot 28 by pushing the guide element 20 to rotate about the fourth rotation axis identified by point 25 causing the tilting wall 70 to open even more by snap fitting.
  • the tilting wall 70 integrally mounts a push element 77.
  • the push element 77 is a wall which protrudes the upper portion 71 of the tilting wall towards the chamber 35. As shown in figures 18 and 19 in the opening position of the opening apparatus 10 the push element 77 does not interfere with the waste bag and follows the curvilinear shape of the tilting wall 70.
  • the push element 77 follows the transverse section with circular-sector shape of the drawer 30, so that during the rotation of the drawer 30 from the opening position to the closing position of the opening apparatus 10 the push element does not interfere with the drawer 30.
  • the push element 77 which protrudes towards the front wall 31 like a hook advantageously allows pushing towards the rear wall 32 a possible wet or humid waste bag that has adhered to the front wall 31 allowing to increase the kinetic energy of the waste bag pushed towards the containment chamber 103.
  • the same effect of increasing the thrust energy by the push element 77 occurs with the side walls 33, as well as with the front wall 31.
  • the drawer 30 also comprises two internal draft walls 38 arranged coupling with the side walls 33.
  • the volume of the chamber 35 of the drawer 30 for containing the waste bag is restricted by the two internal draft walls 38.
  • Each internal draft wall 38 has a shape that follows that of the respective side wall 33.
  • a rear portion 382 of each of the internal draft walls 38 mates with a rear side of the side wall 33 and with sides of the rear wall 32.
  • the internal draft wall 38 gradually moves away from the corresponding side wall 33.
  • the internal draft wall 38 at rest forms a draft angle ⁇ with the respective side wall 33 which is comprised between 2 and 15 sexagesimal degrees, where the draft angle ⁇ is measured in projection on a geometric plane which passes through the ends of the two radial walls 31 and 32 as shown in figure 22 .
  • the internal draft walls 38 are elastic in that they are connected to the drawer 30 only on the side mating between the rear wall 32 and the rear portion 382 of the internal draft wall 38, that is, each internal draft wall 38 can oscillate about the draft angle ⁇ passing from a position of maximum approach with the respective side wall 33 to a position of maximum distance from the respective side wall 33.
  • the internal draft walls 38 allow reducing an engagement angle between the waste bag and chamber 35 with respect to the direction of discharge of the waste inside the chamber 103, reducing the friction between the bag and the walls of the chamber 35 and even more avoiding that a wet or humid waste bag can adhere to the walls of chamber 35.
  • the internal draft walls 38 reduce the inlet opening of the waste bag from the front wall part 31 with respect to the outlet opening of the waste bag from the rear wall part 32.
  • the internal draft walls 38 are also fixed to the front wall 31 so that the internal draft walls 38 are rigidly connected to both the front wall 31 and the rear wall 32.
  • the internal draft walls 38 do not oscillate about the draft angle ⁇ .
  • This alternative is advantageous in that it is provided that the curvilinear flaps of the side walls 33 close with the curvilinear side flaps of the internal draft walls 38 so as to completely close every possible interspace between the walls 33 and 38 so that no interspaces accessible from the outside are formed or where dirt accumulates.
  • an internal face of the front wall 31 of the drawer 30 comprises at least two first strips 39 parallel to each other which rise from the surface of the internal face of the front wall 31.
  • the presence of the first strips 39 allows increasing the friction between a waste bag, even wet or humid, which would otherwise get stuck between an edge of the cap 12 and the edge of the front wall 31 of the drawer 30, due to the centrifugal force following the rotation of the drawer 30 in the passage from the opening position to the closing position.
  • the present of the first strips 39 advantageously allows during the introduction of the waste bag by the user not to slide the bag out of the chamber 35 of the drawer 30 since the first strips 39 are arranged horizontally, i.e. parallel to the rotation axis of the drawer 30.
  • the rear wall 32 is provided to comprise a multiplicity of second strips 34.
  • the second strips 34 are arranged parallel to each other and rise from the surface of an internal face of the rear wall 32.
  • the second strips 32 are arranged vertically, i.e. perpendicular to the rotation axis of the drawer 30, so that when the opening apparatus 10 is in the closing position and the drawer 30 is rotated towards the inside of the containment chamber 103, the second strips 34 reduce the adhesion of a waste bag to the rear wall 32 by not decreasing the kinetic thrust.
  • the presence of the second strips 34 advantageously allows not to reduce the thrust of kinetic energy even of a bag of wet or humid waste.
  • the second strips 34 also have a trapezoidal shape, that is, they comprise a first portion 341 close to the internal face of the front wall 31 and a second portion 342 on the opposite side towards the containment chamber 103, wherein the first portion 341 is more raised from the internal face of the rear wall 32 with respect to the second portion 342, so as to facilitate the sliding of the waste bag by increasing an emptying angle.
  • first portion 341 and the second portion 342 are raised with the same height measure with respect to the internal face of the rear wall 32.
  • the second strips 34 can be U-shaped folded sheets which rise from the internal face of the rear wall 32.
  • the latter alternative allows decreasing the adhesion surface of the bag to the rear wall 32 of the drawer 30.
