Interrelated Control Of Tool And Work-feed Drives Patents (Class 83/298)
  • Patent number: 9596867
    Abstract: An input conveyor, output conveyor, and knife assembly with a blade between the input and output conveyors all reciprocate back and forth as a blade moves perpendicular to the conveyors to cut portioned sized of product, such as ground meat. The cut cycle allows the product feed to keep moving in a continuous manner on conveyors. For ground meat, this system can allow production rates of 150 pieces or more per minute per conveyor line and can improve the accuracy of portioning. The blade is actuated by a profiled cam set that pulls the blade down, and then returns it with a spring to an upper position. The knife assembly can accelerate just after cutting to reduce the potential for sticking to the cut product.

    Abstract: A cut-off machine for cutting off predetermined lengths from a moving length of roll form material such as tubing adapted to be positioned downstream from a source such as a tube mill for receiving a moving length from the mill and severing plural predetermined lengths from the moving length. The machine comprises a plurality of cut-off assemblies which are reciprocated longitudinally of the moving length of material formed by the mill and operated during the movement to sever plural predetermined lengths. The reciprocating and cutting movements are mechanically derived from a motor driven in synchronism with the speed of movement of the moving length. The apparatus includes mechanisms that permit the length of the tubes to be changed while the machine is operating.

  • Patent number: 4852440
    Abstract: An apparatus is of such a structure that it is possible to cut with flying shears, at great cutting accuracy, varying lengths under program control, this apparatus being of a compact construction and operating without mechanical intermediate members to be engaged and disengaged or to be exchanged as is the case with conventional pendulum shears. For this purpose, an eccentric (5) is provided for the oscillating drive of an oscillating yoke (2), as well as for carrying out the cutting stroke on both sides of the yoke (2). This eccentric is coupled with a top cutter bar (4) guided in the oscillating yoke (2) to be movable upwards and downwards, and is driven by controlled drive mechanisms (10) by way of associated gear systems in correspondence with the strip speed and the length of the strip material (6) to be cut off.

  • Patent number: 4809573
    Abstract: A control system is established wherein, when there is a flow of continuous web material (2), an identification phase is provided by increasing the torque signal to a pull roll motor (13) until slippage between the pull roll (12) and continuous web is created at a breakaway torque point, the value of which is measurable. The pull roll motor is then caused to be driven by a signal which creates a motor torque output which is of a value less than the breakaway torque point. Thus, no slippage can occur. As the motor is driven at the lower torque value, a calibration phase is entered wherein an encoder output of the pull roll is properly equated with that of a measuring wheel (9), this phase occuring at a time when there can be no slip between the web-roll interface. The identification-calibration process can be repeated as often as desired.

  • Patent number: 4586412
    Abstract: In a packaging machine of the type in which a "tin-tie" strip is affixed to a bag to allow repeated reclosures of the bag, a machine for cutting a continuous strip of tin-tie material into predetermined lengths and feeding the cut lengths into a bonding station where they are adhesively bonded to the bag proximate its top opening. The machine comprises a frame supporting a pair of electromagnetic clutches, one for selectively coupling a continuously driven shaft to an output shaft to which a tin-tie strip feedwheel is attached and the other for selectively coupling a continuously driven shaft to an output shaft to which a rotary cutting head is secured. Passage of a bag past a sensor triggers the two clutches which function to withdraw a predetermined length of tin-tie material from a supply reel and to sever the strip while feeding the cut length to the bonding station at the same speed as the bag is moving.

  • Patent number: 4497229
    Abstract: A cylindrical, rotating knife is positioned to cut a moving body of flat sheet into predetermined lengths. An electric motor rotates the cylindrical knife. The knife motor is controlled by a system responsive to the travel of the sheet passing under the knife and the rotation of the knife, itself. The two measurements are fed to a control circuit to produce an output analog electrical signal to the knife motor which varies the rotational speed of the knife during the cutting cycle to avoid wastage of the sheet as it is cut.

  • Patent number: 4480456
    Abstract: Cutting of a corrugated fin into predetermined lengths for a radiator in a vehicle. The phase mating is, when the cutter is moved in the direction opposite to the corrugated member, effected at the correcting point where the torque in the cutter is the same as the torque at a cutting point where the corrugated member is moved synchronizingly with the cutter. Thus, automatic phase mating is effected, thereby causing the fin to be cut precisely at a trough of the fin.
