  • Patent number: 4372183
    Abstract: The coordinate slides of a computer controlled punching and nibbling machine are coupled by resilient elements with respective nuts engaging screws driven by motors controlled by computer programming. The resilient coupling between the slides and the respective nuts permits the motors to run and thereby drive the nuts during periods when the slides are held stationary by engagement of the punching and nibbling tool with a workpiece mounted on the upper slide. As soon as the tool is disengaged from the workpiece, the workpiece is quickly moved to the next position by energy stored in the resilient elements. A sensor between each of the slides and the respective nut senses the displacement of the nut relative to the slide and transmits this information to the computer.

  • Patent number: 4367668
    Abstract: An attachment for circular saws that supports a workpiece for movement past the saw blade. The attachment includes a saw-top plate that is adapted to cover and slide over the saw table surface of the circular saw. A guide on the saw-top plate fits within a groove on the saw table to allow longitudinal translational movement of the attachment. The saw-top plate may be supported on bearing rollers mounted to the saw table. A cut-off guide and a workpiece stop are provided on the saw-top plate that serve to position the workpiece relative to the saw blade. A hold-down device, operating also as a blade guard, is used to hold the workpiece secure on the saw-top plate as it is moved past the blade.

  • Patent number: 4348923
    Abstract: A plurality of frozen fish columns having a rectangular cross section are contained in a corresponding number of transversely aligned and laterally spaced tubes constituting a magazine. The lower ends of the columns rest on pushers which are slidable on a number of plastic anvils or blocks comprising part of a vertically adjustable table assembly. A single-edge blade is advanced and retracted at a 30.degree. angle through the lower ends of the frozen columns to sever portions therefrom having a thickness determined by the vertical adjustment of the table assembly. Pushers, which are synchronized with the blade movement, shove the severed portions from the cutting station beneath the lower ends of the tubes onto a conveyor. By controlling the speed of the conveyor the various severed portions, while still uniformly oriented, are transferred in an appropriately spaced end-to-end relationship to another location for processing.

  • Patent number: 4321847
    Abstract: A continuous cold cut slicing system utilizing a slicing machine having a conveyor which feeds a loaf into engagement with a series of drums located on each side of the slicing machine channel; the drums are driven by a variable speed motor with the rotation of the drums providing a feed mechanism of the product to the slicing blade. A gripper assembly is provided which rides on a guide shaft adjacent the channel with the movement of the gripper in the channel constantly being monitored by an encoder and clutch arrangement connected thereto. As the gripper approaches the knife, the encoder and clutch arrangement provide for a drag on the gripper thereby controlling the feed of the product compensating for pull on the knife. Also, since the encoder and clutch arrangement are constantly monitoring the position of the gripper the exact location of the tail end of the loaf being sliced is readily determinable so that a profile compensation control system may be effectively incorporated into the system.
