Definitions

  • the invention is based on a method and a device for detecting the material and the filling state of empties containers in reverse vending machines.
  • Empties reverse vending machines serve to receive individual empty containers, especially bottles or cans, and issue a deposit to the user depending on the characteristics of the entered empty containers.
  • Empties reverse vending machines are known from the prior art record the individual empty containers in either horizontal or vertical orientation and determine the characteristic features of the individual empty containers in this position by means of a detection device. Characteristic features include, for example, the shape, the material, the filling state or filling level, a barcode and a DPG logo recognition.
  • the fill level or fill level of an empties container depends on whether the empties container is completely emptied or still has a content. If an empty container is completely or partially filled, it will be rejected by the reverse vending machine and returned to the customer.
  • empties container The material of an empties container is crucial for the further processing and processing of the empties container in the reverse vending machine.
  • the empties containers are therefore supplied to different other stations depending on their material. Leegut proofer made of glass are used several times and therefore collected. Some plastic or metal empty containers are disposable containers. They are therefore often pressed or crushed.
  • the WO 2006/080851 A1 are reverse vending machines, which are equipped to determine the material and the filling state of an empty container with a balance. Based on this balance, the weight of the empty container is as accurate as possible certainly.
  • reverse vending machines are known, which have a metal sensor or metal detector to separate cans or other containers made of metal from other empty containers. Such reverse vending machines have the disadvantage that they are complicated and expensive to manufacture due to the necessary components for determining the material and the filling state.
  • the invention has for its object to provide a method and apparatus for detecting the material and the filling state of empties containers in reverse vending machines are available that allow the determination of the material and the filling state of the empty containers with less effort, the device to produce cost is and is not prone to wear.
  • the object is achieved by a method having the features of claim 1 and a device having the features of claim 9.
  • the method is characterized in that it is only checked whether the weight of an empties container is below a predetermined weight threshold, and whether upon irradiation of an empty container with light of a certain wavelength range, a transmission of light through the empties container is detected. From the results of the review of the two criteria can be concluded whether it is an empty or filled empty container, and whether the empty container, if empty, made of glass, metal or plastic. Further criteria do not need to be examined.
  • the device according to the invention is equipped with a pressure sensor and a transmitted light sensor. Additional sensors or detectors are not necessary.
  • the pressure sensor it is checked whether the pressure exerted by the empty container on the pressure sensor pressure, which depends on the weight of the empty container, is smaller than a predetermined threshold.
  • the pressure threshold is the corresponding weight threshold assigned. If the weight is below the threshold, it is assumed that the empty container is empty and made of metal or plastic. If the weight coincides with the threshold or is greater than the threshold, it is assumed that the empty container is at least partially filled with a content or made of glass. If the container is made of glass, it can be empty or full. To further differentiate the result of the transillumination sensor is used.
  • the transmitted light sensor detects the transmission of light through the empty container.
  • the transmission and absorption of light depends on the material. Each material has a specific light absorption and light transmission for specific wavelength ranges.
  • Each empty container is irradiated by means of a lighting device with light of a certain wavelength range.
  • the transmitted light sensor detects the light after passing through the empties container. If a transmission is detected, it is assumed that the empty container is empty and made of glass or transparent plastic. If no transmission or only low transmission is detected, then it is assumed that the empty container is made of metal and / or at least partially filled with content.
  • the method according to the invention it is checked whether the light after transmission through an empty container is below a predetermined transmission threshold. If the intensity of the light after passing through the empties container is less than the transmission threshold, it is assumed that the light is predominantly absorbed or reflected by the empty container or its contents.
  • the threshold is determined depending on the typical materials of the empty containers.
  • the illumination device emits monochromatic light. In this way, the transmission of the light to the material of the empty container can be closed particularly accurately.
  • the empty containers are irradiated over a distance by means of the illumination device with light that corresponds to its height or part of its height in the erected state of the empty container. Furthermore, the transmittance of the light is examined on a corresponding path by means of the transillumination sensor. In this way, it can be determined up to what amount the empty container is filled with a content, typically liquid type.
  • the illumination device has a plurality of light sources arranged side by side in at least one row. These may, for example, be light-emitting diodes. These are also suitable for generating a narrowband light.
  • the transmitted light sensor has at least one light sensor, which detects the light emitted by the illumination device after transmission through an empty container.
  • the light sensor may be, for example, a CCD camera or a photodiode.
  • the CCD camera or several adjacently arranged photodiodes allow a spatially resolved evaluation of the light to be evaluated. It is too Note that the measurement is not distorted by stray light or light from other sources.
  • this is equipped with a conveyor belt to receive the empties container in a vertical orientation and to transport to the pressure sensor and the transmitted light sensor.
  • the conveyor belt can be part of a transport device of a reverse vending machine with which the device according to the invention is equipped.
  • the illumination device and the transmitted light sensor are arranged laterally on the conveyor belt.
  • the illumination device is located on one side and the transmitted light sensor on the opposite side of the conveyor belt.
  • the verification of the transmission can take place during the transport of the empties container.
  • the pressure sensor is arranged directly below the conveyor belt.
  • the verification of the pressure exerted by the empty container on the pressure sensor pressure can take place during the transport of the empty container on the conveyor belt.
  • the process of checking the material and the filling state of the empty container is thus integrated into the transport process. The check can be carried out in one pass, which leads to an acceleration of the procedure.
  • FIG. 1 shows a device with a conveyor belt 1 and a pressure sensor 2 in a side view.
  • the transport direction of the conveyor belt 1 is indicated by arrows 3.
  • On the conveyor belt 1 is an empty container 4.
  • the empty container 4 has arrived directly above the pressure sensor, so that the pressure exerted by the empty container 4 on the pressure sensor pressure can be evaluated.
  • FIG. 2 is the device according to FIG. 1 shown in a view in the transport direction 3. From this illustration, the arrangement of the illumination device 5 and the transmitted light sensor 6 can be seen.
  • the transmitted light sensor 6 detects the light emitted by the illumination device 5 and neither absorbed nor reflected by the empty container 4 light.
