    Abstract: Disclosed is a device by which a defective product is removed from a path through which products are continually fed. The device has a feeder feeding products, a sensor detecting defective products, and a remover taking the defective products from the path. The sensor outputs a signal denoting a defect in either the trailing half of a first product or the leading half of an adjacent second product. The remover has a function for obtaining the number which is a quotient obtained by dividing the distance between the sensor and the remover by the length of a normal product. The remover takes out the defective and the adjacent product when the number of products passing the remover is equal to the quotient obtained by the above calculation.

  • Patent number: 4214663
    Abstract: Objects on a delivery conveyor are detected by a photo-detector connected to a multi-bit shift register which is clocked by a pulse generator connected to the delivery conveyor. A NOR gate is connected between two outputs of the shift register and the shift register resets to erase information relating to undersized objects. Another circuit having NAND gates connected to a series of shift register outputs and to a counter connected to the pulse generator determines the presence of objects over a base size. A comparator connected to the counter provides a signal to a microprocessor, connected to the shift register resets, to erase information relating to an oversize object. Another section connected to the intermediate output of the shift register detects the location and length of gaps between adjacent objects. This section provides information to the microprocessor which through its connections to the shift register erases information relating to the leading object if the gap is too small.

Vials are advanced by an in-feed star wheel, a rotating vial deck and an out-feed star wheel having the same number of vial locations and vial orbit speed. Along the vial deck orbit, each vial is successively clamped to a rotatable puck, spun momentarily to swirl the liquid therein, inspected for particulate content, and unclamped. Further rotating decks carry circumferentially arranged television cameras and light sources, respectively. Each camera looks radially inward, axially through an orbiting periscope and then radially outward to inspect a vial.

  • Patent number: 4170306
    Abstract: A control apparatus for processing the electrical signals generated by an optical ratiometric color sorting scanner, said apparatus generating signals to cause the rejection of articles which differ in color and/or size from predetermined limits. In the scanner, two electrical signals are generated which are responsive to two different spectral regions or pass bands of the radiant energy reflected by the product being sorted. These signals are superimposed on a slowly varying signal responsive to the standing background light. The control circuitry processes the signals to delete the standing light signal and spurious noise signals and determines if the ratio between the signals is greater than or less than a predetermined value, or alternatively, determines when the ratio between the signals is not within a predetermined acceptable range and generates a delayed reject signal thereafter. Other circuits provide signals to a meter for displaying the present reject rate and particle feed rate.

  • Patent number: 4147619
    Abstract: Apparatus for sorting items, such as peeled whole potatoes, which, in the absence of abnormalities, exhibit a substantially uniform light reflectivity, includes an illumination chamber through which the items to be sorted are passed successively as a stream. Light sensors are focused on a cross-sectional slice of the illumination chamber through which the items pass, each of these light sensors being focused on only a small portion of the slice. Electronic circuitry in conjunction with the light sensors counts the number of such sensors sensing abnormalities. If the number of sensors sensing abnormalities is greater than a predetermined minimum, a reject signal is produced. If desired, the circuitry may be arranged to also determine whether the number of sensors sensing abnormalities is greater than a predetermined percentage, for example, 50%, of the total number of sensors sensing the item, and thus produce a second reject signal if the abnromalities make up more than the predetermined percentage.

    Abstract: An on-line detector for peach pits and peach pit fragments and the like remaining in peach halves following a pitting operation includes a sealed housing bordered on one side by an inclined view plate disposed between a feeding belt and a take-away belt. A peach half, pit cavity down, is passed by a viewing line above the view plate. Two different wavelengths of light are directed toward the viewing line and are reflected by a passing fruit section toward an array of light sensors. One of the wavelengths of light is controlled in on-off condition by a clock, being turned on during only a portion of each clock cycle. Output from each one in the array of light sensors is sampled during the portion of each clock cycle that the one wavelength is on, and differenced with the light sensor output from that sensor when the other wavelength only is on. Differencing occurs during each clock cycle and a difference output appears only in the presence of a pit or a pit fragment.

  • Patent number: 4132314
    Abstract: Disclosed is apparatus for sorting objects, e.g. tomatoes, according to both size and color. A preferred embodiment can sort the objects into fourteen size/color categories and yet requires only two photodetectors. The objects travel on a conveyor belt past a sensing station having a light source to illuminate an object and a pair of phototransistors for receiving light reflected from the object in two different color bands, e.g. red and green. The phototransistors produce a pair of output electrical signals. An analog divider forms a ratio of the electrical signals and the peak value is stored and compared with preset limits to produce a color category signal. A size category signal is derived on the basis of the time duration of the signal produced by the summation of the phototransistors' signals.
