Abstract:
An endless conveyor for receiving, conveying in a conveying direction and delivering rotation-symmetrical products. The conveyor is provided with at least a single endless transport element, as well as with a number of transverse elements extending perpendicularly to the conveying direction. At least a single hourglass-shaped roller is provided on each transverse element, wherein the rollers form a corresponding at least single row and wherein between each two successive rollers in a row there is a conveying position for a product. The conveyor includes a lay-on portion and a successive downstream portion which are situated in different planes, the angle between these planes being greater than 180° as measured from above.
Abstract:
An apparatus for transferring products, such as fruit, onto, and supplying the same to, a conveyor, preferably a roller conveyor. The apparatus is provided with two flat endless conveyor belts positioned obliquely relative to a vertical plane, continuous in the conveying direction, functioning as a V-channel. The endless conveyor belts first extend substantially parallel to the conveyor in the conveying direction, wherein from a well-defined location, the endless conveyor belts bear off the conveyor and continue at different angles relative to the conveying direction, with the conveyor belts diverging mutually. The apparatus accommodates a stream of food products, such as fruit, with greatly varying sizes, to be transferred gradually and in the proper sequential order onto the conveyor, thereby considerably reducing injuries to the food product during transfer.
Abstract:
The present invention relates to a system for determining characteristics of products of generally unequal size, e.g. apples, which are conveyed on product carriers, such as rollers of a conveying apparatus, and pass the system, the system comprising a detection device, arranged at some distance from the products, having a transmitter section and a receiver section, as well as a signal processing unit for processing signals to and from the system, including the signals of the receiver section for determining the characteristics, the system further comprising: a sensor which, prior to the passage of a product, scans the size of each passing product and produces a corresponding scanning signal, and a displacement device, for positioning, in accordance with each scanning signal, at least the receiver section of the detection device at a well-defined distance during the passage of each product. With such a system, in an advantageous manner, on-line, characteristics such as firmness and sugar content of fruits can be determined. These characteristics can be used real-time as a selection criterion during sorting of large amounts of fruits.
Abstract:
A gripper for lifting a stack (30) of boxes, trays or such substantially rectangular articles, the gripper being provided with a gripper frame (11, 12; 51, 52) and two flat gripper leaves (21) which are movably connected to the gripper frame (11, 12; 51, 52) so as to be movable from an open position to a closed position, the gripper leaves (21) being substantially flat and each being provided near a lower end thereof with a carry strip (20, 22), which carrying strip (20, 22) is hingedly connected to the gripper leaves (21) so as to be movable from a release position in which the carrying strip (20, 22) extends in the same plane as the associated gripper leaf (21) to a carrying position in which the carrying strip (20, 22) is substantially perpendicular to the gripper leaf (21) and is located between both griper leaves (21), the gripper being provided with control means (14–19, 23) for controlling the gripper leaves (21) and the carrying strips (20, 22).
Abstract:
An apparatus for transferring separate products, such as eggs and fruit, from a feed conveyor to a packaging apparatus includes a feed conveyor provided with at least one row of product holders, a receiving conveyor provided with brushes for receiving the products discharged from the feed conveyor and a feed-through conveyor connecting to the receiving conveyor for further conveying the products to a packaging apparatus. The apparatus is provided with electrically operable discharge members disposed above the feed conveyor. The fall trajectory of the articles discharged from the feed conveyor is such that the articles end up at substantially the same landing location on the receiving conveyor, independently of the speed of travel of the feed conveyor at the moment of discharge.
Abstract:
An apparatus for transferring eggs from a first roller conveyor (1) to a second conveyor (2), with an orienting operation taking place during the transfer, so that the eggs on the second conveyor (2) are all oriented with their points to one side, the rollers (3) of the first roller conveyor being substantially hourglass-shaped and comprising a roller center part (3a) which is substantially cylindrical, the apparatus comprising pre-orienting devices (4) for bringing the eggs on the first roller conveyor (1) into a pre-oriented position (A), the apparatus being provided with a transfer conveyor (5) having grippers (6) which are each adapted to pick up an egg from the pre-oriented position (A), the grippers (6) being adapted to bring the eggs into an aligned position (C) and to transfer the eggs from the aligned position (C) to the second conveyor (2).
Abstract:
A probe for an egg-testing device includes a probe tube with an annular magnet disposed at a bottom end thereof. In the probe tube, a spherical excitation member is magnetically retained by the annular magnet. The probe is axially movable in a metal tube around which a bobbin is wound. In a rest position, the probe is retained by the magnetic attractive force between the metal tube and the annular magnet. The probe is brought into an operating position by an excitation pulse supplied to the bobbin, which pulse is provided by a control unit, taking into account the diameter of an egg to be tested and the conveying speed of a conveyor.
Abstract:
A method and apparatus for releasing articles from holders mounted on a conveyor travelling at varying speeds, the varying ballistic trajectory of the released articles being automatically compensated for, depending on the speed of the conveyor, by shifting the discharge locations of the article holders. One or more adjacent ones of the releasing members for each delivery station, arranged side by side in the direction of travel of the conveyor, are fixed against movement in the direction of movement of the conveyor.
Abstract:
A transfer system for providing faster and increased volume processing of eggs having an overhead positioned egg conveyor. A rotating brush wheel positioned underneath the conveyor receives eggs and includes a first and second pluralities of bristles having, respectively, lesser and greater stiffness. An egg receiving reservoir exhibits a receiving lane positioned underneath and in alignment with the brush wheel for receiving and redirecting the eggs in a lane dedicated fashion to a subsequent egg handling operation. A plurality of spool bars are arranged in parallel extending and spaced apart fashion and defining a number of individual egg conveying lanes and each further include first and second spool bar portions secured in end-to-end fashion to establish an overall dimension. First and second drive supports are arranged at opposite ends of the spool bar portions, a third drive support arranged within the egg transfer mechanism and supporting opposing and intermediate engaging ends of each pair of spool bar portions. The intermediate drive support prevents sagging of the intermediate ends of the spool bar portions.
Abstract:
A vision system incorporated into an item of egg handling equipment, the system incorporating software control for detecting at least one of color shades and defects on both brown and white eggs. An enclosure incorporates a plurality of high resolution producing cameras, these communicating via cable with a switch to a remote vision PC system. A non-linear shaped diffuser is mounted along an open facing bottom of the enclosure for facilitating uniform lighting throughout an open interior of the enclosure associated with the cameras. The cameras are operable to produce multiple, high resolution images of each of a plurality of eggs continuously transported along the associated egg handling equipment, for classifying types of defects that are allowable and those that must be rejected, as well as assisting in the segregating of the eggs into more consistent shaded groups for eventual packaging.
