Abstract: Methods are provided for locating 3D rectangular objects on surfaces, each object having substantially the same X, Y and Z dimensions as the other objects on the surface. An image of a surface having objects arranged thereon is obtained. The image includes pixels arranged in rows and columns. As each object has the same Z-dimension, the surface shown in the image is planar. From the image, the X and Y dimensions, and X, Y coordinates of a center for each object are determined. Edge points are detected utilizing gradient evaluation. The X and Y dimensions of the objects are determined by counting the frequency of distances between edge points and X, Y coordinates of the center location for each object is determined by identifying positions in the image that have a concentration of edge points at a distance equivalent to one-half the size (X or Y dimension) of the objects.

Abstract: A method and an apparatus for sorting waste into different waste types. A first division of the waste is effected into at least two waste types in that each waste type is placed in a bag or container (100, 101) which is provided with at least one marking which indicates the waste type for which the bag is intended. The containers are collected and mixed together for transport to a common sorting plant in which the containers pass an identification mechanism (6) establishing, with the aid of the marking on the bag, the type of waste for which the bag is intended. The information is transmitted to a recording and control system (7) which, via a signal transmission device (73) switches a separating mechanism (9) for adjusting the same into a position in which the bag, on its passage of the sorting plant, is brought into a position reserved for that type of waste indicated by the marking on the container.

Abstract: Apparatus and method for performing multiple level sortation operations upon a number of randomly ordered garments. The garments are identified by unique identification data, which can be scanned and entered into a computer. The computer remembers the order in which garment identification data has been. The garments are then transferred in their entered order to a first sortation assembly in which a rotating wheel assembly accepts and selectively releases garments during indexed rotation of the wheel at one of a number of stop points. Each stop point has associated with it a receiving rail, where each rail represents a different group within a first sortation level. The computer recognizes which receiving rail is the correct rail for each garment according to the first sortation criteria and signals the release of the garment at the correct stop point. The garments collected on each receiving rail comprise a group of first sorted garments according to the first sortation criteria.

Abstract: A carton glue monitoring system includes a conveyor moving a plurality of cartons in a first direction. An encoder provides pulses at a rate proportional to conveyor line speed. A glue applicator applies a glue strip having a fluorescent material added thereto to the cartons on the conveyor. A glue check station includes a UV source for illuminating the fluorescent material in the glue and a UV sensor for sensing the fluorescent material. The glue station further includes a glue skip detector and an excess glue detector for generating a glue flag and for holding the glue flag until the carton exits the glue station. A glue shift register includes Y registers and is connected to the UV sensor and the encoder for shifting the glue flag in the Y registers. Y is proportional to the encoder rate and a distance between the rejection marking device and the glue station exit minus the carton length.

Abstract: The invention relates to a method and device for sorting returnable bottles, cans and other returnable packages. In the method, a returnable package is transferred by means of a transferring device to an identification device having a data processing unit and a data storage unit in which data concerning different types of acceptable package forms and/or package colors are preregistered. An identification index corresponding to form/color is given to the identified package and the index is transferred to a pushdown storage of a first sorter located after the identification device, to a first lowermost free storage location of the pushdown storage. The identification index is compared with a specific index related to the sorter. If the identification index corresponds to the specific index of the sorter, a sorting is performed with the sorter and the returnable package is transferred away from a main conveyor.

Abstract: A document dispensing system for dispensing documents or bills from a source to a customer access receptacle or a reject bin depending upon certain characteristics of the bills or the manner in which they are fed. Sensors which are positioned along a dispensing path are sampled to produce first and second states therein in accordance with the presence or absence, respectively, of bills in the dispensing path. The states of the sensors are stored to provide short term and long term histories of the sensors along with a time in transport for each of the bills in the dispensing path. The short and long term histories and the time in transport are utilized for evaluating the status of each of the bills in the dispensing path with regard to predetermined criteria such as, for example, "double thickness", or "bill too long", and for producing a control signal which controls a diverter gate to divert the bills into the access receptacle or reject bin in accordance with the evaluation.

Abstract: A circuit for detecting the color of fruit on a plurality of conveyor paths by measuring the light reflected from the surface of the fruit at a viewing station at each path. The circuitry operates to develop a pair of signals at each of the conveyor paths which signals are provided by measurements of the amount of light reflected from the fruit within two distinct bands of wavelengths of light. These signals are routed, one pair at a time, through a pair of amplifiers and a pair of voltage comparators to develop appropriate discharge signals for each of the conveyor paths. A sequencer controls a pair of switching circuits which direct the signals, one at a time, to the amplifiers. The sequencer also directs any signals from the comparators to driver circuits which provide power to divert cull fruit from each conveyor path.
