Definitions

  • the invention relates to a device for detecting characteristic features of an empty container having at least one planar support element on which the empty container with a lateral surface of the same can be applied to a contact surface of the support element, with a carrier for supporting the empty container and at least one optical sensor for detecting at least a characteristic feature of an empties container and with a transport / sorting device, which transports and sorts the empties container after detecting the at least one feature.
  • the invention relates to a method for detecting characteristic features of an empty container, wherein a lateral surface of the empty container is scanned by means of an optical sensor and wherein the empty container is guided during the scanning under rotation about its longitudinal axis with a lateral surface on a support element.
  • Conventional reverse vending machines have an input module for accepting empties containers, for example bottles and / or beverage cans. From a transport module, the entered empty container is transported to a detection module. In the detection module, the empty container is rotated by means of other drives, so that attached to the empty container identification features, eg. As barcode, deposit and / or other special features can be detected by means of an optical sensor. For determining the identification features, at least one sensor, for example a bar code reader and / or a camera, is arranged on the device. It is also possible to provide a plurality of sensors for determining various features. About another transport module is the empty container from the detection module fed to a sorting module.
  • the empty container is fed to one of several possible conveying elements, which guide the empties to collection stations, depending on the detection features determined by the sensors.
  • the empty container for volume reduction is fed to a compacting module.
  • Such devices are also referred to as crushers.
  • an input module and a transport module for a reverse vending machine are known.
  • the input module has a drainage channel formed from two curved rods, via which the empties container inserted through an input opening in an outer wall of the reverse vending machine is fed to the transport module arranged below the input opening.
  • the input module has guide means which ensure that the empties container is placed upright on the subsequent transport module.
  • the transport module is designed here as a substantially horizontally oriented endless conveyor belt.
  • a detection module for reverse vending machines is known, are scanned in the standing on a conveyor belt conveyed empty containers from an optical sensor.
  • a stationary arranged plate-shaped support member is provided for this purpose, which is aligned perpendicular to the empty container receiving section of the conveyor belt and with the transport direction einschiebt an acute angle.
  • the empty containers supported on the conveyor belt are supported on the stationarily arranged plate during transport. Due to the frictional force acting between the plate and the empty container, the empty container is set in rotation in the transport direction on transport on the conveyor belt.
  • the optical sensor is now arranged and aligned such that it the empty container during its rotation scans on the plate and so fully covers the lateral surface of the empties container. In this way it can be ensured that the barcode, the deposit sign and / or another characteristic feature of the empties container can be reliably identified regardless of its original relative position to the optical sensor.
  • a device for sorting empty containers which are supplied to the device via a transport module.
  • the sorting device Above an endless conveyor belt of the transport module, the sorting device has a drive shaft extending essentially parallel to the transport direction of the empty container.
  • the drive shaft sorting arms are rotatably connected, which include a in the effective range of the sorting device incoming container on both sides with distance.
  • the sorting arms convey the empty container to one side or the other of the conveyor belt.
  • the empty containers can thereby be supplied to one of two predetermined conveying elements. If more than two conveying elements are to be realized, several sorting devices can be arranged one behind the other.
  • a disadvantage of the solutions known from the prior art is that the functions input, transport, detection and sorting are realized by means of separate functional modules.
  • the function modules represent separate units, which are arranged one behind the other and coupled with each other in terms of information technology. Due to this, today's reverse vending machines are relatively large. Furthermore, they are expensive to manufacture and maintain due to the large number of functional modules and relatively error-prone.
  • Object of the present invention is therefore to provide a particularly simple, compact and cost-effective device and a simplified method for the return of empty containers available.
  • the invention is characterized in connection with the preamble of claim 1, characterized in that the carrier is formed by the at least one support member and that the at least one support member is rotatably supported about a substantially horizontal drive axis such that the empty container of a Input position in which the empties container can be placed on the at least one support element, in at least one transfer position, from which the empties container can be transferred to a downstream functional module, can be brought.
  • the particular advantage of the invention is that the support element supports the empty container and at the same time serves as a carrier of the empty container.
  • a separate transport module for carrying and transporting the empties container is not required.
  • the core idea of the invention here is to execute the input module, the recognition module and the transport / sorting module connecting the input module and the recognition module as a functional and structural unit. This reduces the size of the empties reverse vending machine on the one hand. On the other hand, the entire device can be operated with a single drive, resulting in significant cost advantages.
  • the risk of faults and failures is reduced because the number of components is reduced and the data-related coupling of separate functional modules for input, transport and detection of the empty container can be dispensed with.
  • the empties container is guided with its lateral surface rollable on the support element and scanned with rotation about its longitudinal axis of the optical sensor.
  • this allows the lateral surface of the empty container full circumference of be detected by the optical sensor.
  • the characteristic features of the empties container for example its geometry, its surface texture and its optical material properties, as well as a barcode and / or a token, can be read out independently of the orientation of the empties container during the input.
  • the rotation of the empty container about its longitudinal axis can take place without the provision of an additional drive solely due to the rotational movement of the support element, on which the empty container is rolled out with its lateral surface around the drive axis.
  • the support elements can be rotated in the opposite direction.
  • the longitudinal axis of the empty container is oriented parallel to the drive axis in the input position and / or in the transfer position. Due to the parallel arrangement of the longitudinal axis and the drive axle of the empty container rolls in the rotation of the support elements about the drive axis on its lateral surface. Slipping or slipping of the empty container along the support element is avoided.
  • the drive axle of the support element can be oriented in the direction of the user at an angle between 0 and 180 degrees. The preferred orientation of the drive axle depends on the downstream sorting paths, the structure and the placement of the machine.
  • the support element carrying the empty container is arranged in the input position and / or in the transfer position rotated by an acute angle downwards.
  • the acute angle here is greater than 0 ° and less than 45 °.
  • the acute angle is greater than 0 ° and less than 15 °.
  • the empty container is thereby in the input position and / or in the transfer position as a result of acting on him Weight force spent in a defined rest position.
  • the rest position can be realized mechanically here, for example, by a support element itself and by a stationary mounted holding element. Entering empty containers is simplified insofar as the customer does not have to position the empty container exactly. Rather, the container takes its rest position automatically.
  • the transfer of the empty container to a downstream functional module is simplified, since the position of the empty container after detecting the same by the optical sensor is known exactly.
  • the empty container is brought by the weight alone in the input position and / or the transfer position, can also be dispensed with a separate drive, so that the structure of the device further simplifies and the costs are reduced.
  • the empties container can be spent in the input position and / or in the transfer position due to the weight acting on it in a defined rest position by a special geometry and orientation of the support element without a stationary mounted holding element.
  • the support arms of the support elements are aligned symmetrically in the input position for receiving an empty container to a running through the drive axis vertical plane.
  • the support elements can have different geometries.
  • the support element is at least partially planar and / or curved and / or angled formed.
  • a flat support element is advantageous if the empty container with a predetermined Roll rotation speed on the support element and should be moved from the input position to the transfer position.
  • a flat support element is simple and inexpensive to manufacture.
  • a bent and / or angled support member has the advantage that the empty container in the input position and / or in the transfer position and / or the same can be set from the input position to the transfer position at predetermined positions on the support element.
  • This geometry offers at least one possible rest position in the input position and / or forwarding position without the need for additional components.
  • An angled support member makes it possible to tilt a non-circular in cross-section, but for example rectangular empty container by the rotation of the support member about its longitudinal axis and to detect an initially hidden, not detectable by the optical sensor part of the lateral surface.
  • the support element has at least two structurally identical, angularly offset about the drive axis arranged support arms.
  • the support arms protrude radially from the drive axle. Between adjacent support arms, a support angle of equal to or less than 180 ° is included.
  • a support angle of equal to or less than 180 ° is included.
  • three identical support arms can be arranged offset by a same support angle to each other about the drive axis.
  • the three support arms can in this case have an equal radial length.
  • the support element hereby takes the form of a rotor. Each revolution of the rotor, a number corresponding to the number of support arms number of empty containers are inserted into the device, scanned in the same and spent in the forwarding position. This increases the throughput of the device.
  • the support arms form an angled support element with the advantages described.
  • the dimensions of the support elements are selected such that upon rotation of the empty container about the longitudinal axis of its entire surface with at least one, preferably stationary, optical sensor can be scanned.
  • the empty container after the optical scanning a predetermined function modules, for example, for collecting, compacting, onward transport, return or for further processing, are supplied.
  • the support element is rotated at an individually selected rotational speed in and / or counterclockwise about the drive axis.
  • this also integrates the sorting function into the device according to the invention.
  • a separate sorting module can thus be dispensed with as well as on a sorting module and the detection module connecting second transport module.
  • the compact design of the device is thereby further promoted.
  • due to the omission of further drives, guide means or the like the costs and the susceptibility to failure of the device decrease.
  • the dimensions of the support arms of the support member are selected such that the empties container is fully scraperable while rolling it on the contact surface of the support member.
  • two offset from each other optical sensors are provided.
  • the area of the surface of an empties container detected by the sensors is increased.
  • the unrolling of the empty container for detecting the lateral surface, in particular the arranged on the lateral surface characteristic features can thus take place to a lesser extent.
  • On the support elements or rolling empties containers are optically scanned by the two sensors from different directions.
  • the two sensors can be aligned with their optical axes such that at least one first sensor detects the empty containers, in particular in the input position, and at least one second sensor detects the empty containers when unrolling on the support elements and / or in the transfer position.
  • the angle of rotation of the empties container required for complete detection of the lateral surface is reduced compared to a previous solution by the size of the angle between the optical axes of the sensors. Since the angle of rotation of the path of the empty container during unrolling is proportional, thereby reducing the same time the radial length of the support arms and the dimensions of the support member.
  • the device is equipped with a reflector unit which deflects light in the direction of the at least one sensor. This light would not get to the sensor without the reflector unit.
  • the reflector unit thus leads to the sensor not only detecting light reflected directly from the surface of an empties container in the direction of the sensor, but also light which is reflected outside an aperture angle of the sensor centered about the optical axis of the sensor.
  • the sensor can detect, for example, not only the surface facing him an empties container, but also the laterally aligned areas.
  • the reflector unit allows the use of only a single sensor.
  • the reflector unit is introduced into the detection area or the measuring beam of the at least one optical sensor in such a way that the detection area can be divided into partial detection areas or the measurement beam into partial measuring beam, and the empty container can be scanned by at least two detection areas or measuring beam bundles offset by a measuring angle with individual opening angles is.
  • the at least one optical sensor and the reflector unit may be positioned such that the detection area or the measuring beam and / or the partial detection areas or partial measuring beam of the sensor are arranged symmetrically with respect to a plane extending vertically through the drive axis.
  • the reflector unit can have a first reflector arranged symmetrically with respect to this plane, with two reflector segments arranged at an angle to one another, which divide the detection area originating from the optical sensor or the measuring beam into two partial detection areas or partial measuring beam.
  • the reflector unit may have two spaced-apart and second symmetrical to the central plane and the drive axis arranged second reflectors for deflecting the two generated on the first reflector part detection or partial measuring beam in the direction of the support elements.
  • the angle of rotation of the empties container required for the complete detection of the lateral surface is reduced by the size of the angle between the two observation directions or partial measuring beam bundles. Since the angle of rotation of the path of the empty container during unrolling is proportional, thereby reducing both the radial length of the support elements and the dimensions of the support elements at the same time.
  • the dimensions of the support element can be further reduced if there is no requirement for a scan of the complete lateral surface, or if there is a request to the user to align the empties container, for example, such that the empties container with the barcode up in Direction of the sensor is inserted.
  • a reduction in the dimensions of the support element is also possible if the empty container has no barcode, but only a shape recognition is performed. In this case, because of the rotational symmetry of the Empties container this not turned at all. The dimensions of the support element can therefore be reduced to the diameter of the empty container.
  • a distance of the at least one optical sensor from the drive axis is selected such that the measuring beam has a scan field width measured transversely to the center plane in the area of the drive axis which is at least twice as large as the radial length of the at least one support arm.
  • the empty container during its rotation about the longitudinal axis of a single, preferably fixed optical sensor can be detected. If the scan field width of the optical sensor corresponds to twice the radial length of the support arm and the empty container is supported in the input position at a free end of a first support arm and in the transfer position at a free end of the second support arm, the support element has its necessary for complete detection of the empty container minimum diameter.
  • the empty container is detected in the input position and the transfer position of the optical sensor.
  • the position of the empty container, or the position of the support element, during the detection or sorting movement is constantly analyzed. If all required features are detected, the rotational movement, depending on the downstream sorting process, continues to sort, possibly with a correction of the rotational speed continues or immediately interrupted. In this case, at least one change of direction is required for the further sorting movement. This process substantially increases the throughput of the device.
  • the support member can be rotated back and forth or tilted for the detection of the characteristics of the empty container.
  • This is particularly advantageous in a device in which the rest position is ensured by the geometry of the support element in the input position and / or forwarding position.
  • the scanning field of the sensor widens on both sides of the axis of the rest position. If, during the rotation of the support element in one direction, the features are not detected, the direction of rotation can be changed.
  • the empty container in the other part, with respect to the axis of the rest position the scanning field is unrolled and the previously hidden part of the lateral surface is scanned.
  • the invention in connection with the preamble of claim 16 as a method, characterized in that the empty container due to rotation of the support member about a substantially horizontal drive axis automatically from an input position, placed in the empty container on the at least one support element is, comes in one or more forwarding position on which the empty container is handed over to a downstream function module.
  • the particular advantage of the invention is that the rotation of the empty container about its longitudinal axis automatically, that is, without additional drives based solely on the weight acting on the empty container weight. Due to the rotation, another subregion of the lateral surface of the empties container constantly gets into the detection range of the optical sensor. As a result, in the input position, hidden subsections of the outer surface of the empty container, which are not detectable by the optical sensor, can be optically detected during the unwinding from the input position into the transfer position. Accordingly, a barcode or a token is detected by the optical sensor irrespective of the original orientation of the empty container in the input position during the rotation along the support element. By dispensing with separate drives, the detection method is greatly simplified.
