  • Patent number: 8925434
    Abstract: A tablet splitting apparatus capable of reducing fluctuations in weight of split tablet pieces even with simple advanceable-retractable blades is provided. A holding mechanism holds a tablet to be split at a cutting position. In reducing the gap between a pair of opposed blades, which are advanced and retracted with respect to the cutting position, to cut the tablet, the holding mechanism continuously holds the tablet until the tablet is caught between the pair of opposed blades of a cutting mechanism. After the tablet is caught between the pair of opposed blades, the holding mechanism release the tablet and only the pair of opposed blades hold the tablet. The opposed blades are caused to cut into the tablet after the holding mechanism releases the tablet, preventing a crack caused in the tablet ahead of the opposed blades from being curved or increased.

    Abstract: A food processing apparatus for conveying food items such as carrots and the like to a cutter comprises a conveyor having a plurality of pockets for receiving the food items. The conveyor moves in a conveyor direction to the cutter for topping, tailing, or cutting the food items. A stationary feed chute is disposed adjacent a side of the conveyor for transferring the food items to the conveyor. The apparatus is disposed at a compound angle measured from the horizontal plane such that the food items are transferred from the feed chute to the conveyor by gravity. Food items which are not received into the pockets of the conveyor are carried by their momentum of feed to fall off from the conveyor by gravity in a direction away from the cutter, and are collected for return to the feed chute. This decreases the amount of misfed food items from reaching the cutter and the amount of uncut or improperly cut food items at the output of the cutter.

    Abstract: In a cutting system and method for cutting pattern pieces from flexible sheet material, after the cutting the cut pattern pieces are separated from the waste material by moving the material forwardly to a separating station at which the waste material is pulled from one point to another so as to be tensioned and constrained to move along one path to one delivery station, while cut pattern pieces are not similarly pulled or tensioned but instead are allowed to move by gravity to a different path leading to another delivery station. An associated means, such as a roll with a resilient outer surface or a plurality of plungers, applies forces to the material to aid gravity in the separation of the pattern pieces by tending to push such pieces from the waste material. The material may also be vibrated to assist in the dislodgment of the pattern pieces from the waste material.

The inspection station utilizes a raster scan television camera and output signals therefrom are used to actuate one of a plurality of cutting devices in order to sever from the articles those portions containing blemishes. The severed portions containing blemishes are thereafter separated from the remainder of the articles by either a screen or by air jets.

  • Patent number: 4576071
    Abstract: The food product sensor and trimmer apparatus and method may be used to detect and remove defects from french fried potato strips or other elongated food products as they are conveyed in separate channels on a conveyor belt. Such apparatus comprises a defect sensor for each channel including a plurality of light detectors which detect two different wavelength light bands, such as visible light and infrared light, reflected from the surface of the food product to determine the length of the product, the size of the defect and the position of the defect on the product. Visible light and near infrared light are reflected from the product and sensed by different detectors and the ratio of detected visible light to infrared light determined to detect defects and locate them relative to the opposite ends of the product.

  • Patent number: 4515050
    Abstract: Sheet metal plates are automatically fed for processing to a computerized numerically controlled sheet shear arrangement by means of the feeding apparatus. This feeding apparatus comprises a feeding bar arranged parallel to the cutting blades of the sheet shear arrangement and movable perpendicular thereto. Elevationally displaceable or movable holding elements are arranged on opposite sides of the feeding bar. On the side of the cutting blades the holding elements retain a first sheet metal plate intended to be cut and on the opposite side grip a second sheet metal plate which has been elevated by suction elements. During the cutting operation performed upon the first sheet metal plate the second sheet metal plate is drawn to a working table within an overlapping time interval and placed upon the working table.

  • Patent number: 4512227
    Abstract: Automatic shearing apparatus is provided which includes a shear provided with a shearing blade, a feeding unit for feeding sheet metal to the shear, and at least one movable carrier arranged downstream of the shearing blade. The movable carrier is controlled to receive and store the sheared pieces and then to return them to the feeding unit or, selectively, to cause the sheared pieces to reach a controlling device for sending to a piece discharge area. The feeding unit can be a manipulator, with rectilinear motion perpendicular to the shearing blade, and a rotator, both located upstream of the shearing blade. The manipulator and rotator function to receive, rotate and feed the metal sheets to be sheared, as well as to receive, rotate and refeed to the shear the sheared pieces returned by the movable carrier.

    Abstract: The apparatus forms upon a pallet an orderly arrangement of stacks of sheet metal sections or cuttings at predetermined places with the aid of supporting rake means and abutment means following sheet metal shears. Scrap metal cuttings obtained by trimming or at the end of a sheet metal plate are received by a separate waste scrap metal collecting means positioned beneath a sheet metal feeding or infeed table and movable below the sheet metal shears. The sheet metal sections or cuttings are caught and entrained by automatically controlled catching means, such as an entrainment bracket, disposed at the supporting rake means, so as to be able to be moved horizontally in order that large accelerations and velocities can be achieved during the stacking of the sheet metal sections or cuttings.
