  • Patent number: 4114489
    Abstract: A control arrangement for a dividing apparatus for dividing or cutting continuously fed strip stock of variable thickness. The dividing apparatus includes a drive arrangement for driving a cutting unit in a horizontal and vertical direction with an arrangement being provided for vertically adjusting the height of the cutting unit. A control arrangement is provided which includes a measuring device arranged in the dividing apparatus at a position upstream of the cutting unit, as viewed in the feed direction of the strip stock, with the measuring device dividing an output signal indicative of the measured thickness of the strip stock, which output signal is directed to control elements so as to correlate the speed of the drive arrangement and adjust the height of the cutting unit between minimum and maximum values in correspondence with the measure thickness of the strip stock.

  • Patent number: 4067458
    Abstract: Apparatus for the unstacking and transportation of blanks into a subsequently arranged operating chamber of a processing machine, wherein the blanks are transferred from a stack of blanks, by hoisting devices, especially suction bridges, includes a suspended conveyor which conveys the blanks by way of a double-blank control device to a centering station. From the centering station, the blanks, centered in their position, are transferrable into the operating chamber, optionally by way of an intermediate station. At least two stacks of blanks are disposed in series in the conveying direction of the blanks on at least two elevator carts movable at right angles to the conveying direction. Each elevator cart is associated with a separately operable suspended conveyor with associated hoisting units. A further, continuously driven suspended conveyor is provided downstream of the double blank control device which conveyor spans a double-blank depositing unit and terminates over the zone of the centering station.

  • Patent number: 4062213
    Abstract: A control system for controlling operating steps of a press including a coded pulse generator for providing a coded pulse output in dependence upon the position of a drive shaft of a press drive and a signal generator responsive to the stroke rate of the press for providing an output signal proportional to the stroke rate of the press. A summing unit receives the coded pulse output from the coded pulse generator and the output signal of the signal generator for providing a corrected coded pulse output. A decoding unit is provided for decoding the corrected coded pulse output of the summing unit and for supplying a decoded pulse output to a pulse distributor which provides an output on at least one of a plurality of output paths in accordance with the decoded output of the decoding unit. At least one regulating member for controlling an operating step is coupled to the pulse distributor for receiving an output therefrom in accordance with the position of the drive shaft and the stroke rate of the press.

  • Patent number: 4037730
    Abstract: A press line having a transfer system for transferring workpieces from a processing station of one press to a processing station of a subsequent press. The transfer system includes a track extending over the entire interspace between the two successive presses and a single transfer slide mounted for horizontal movement along the track. At least one pair of grippers pointing in opposite directions is mounted on the slide and a single storage station is provided between the two successive presses with a drive being provided which controls the movement of the slide in accordance with the travel path thereof.

  • Patent number: 4013002
    Abstract: A process and apparatus for the positive actuation of a weight compensating mechanism for a ram of a press accommodating a tool set. The process includes the detecting of at least one condition indicative of the changing of a tool set of the press, preventing working operation of the press in response to such detected condition, and then initiating operation of the weight compensating mechanism. The process also includes the enabling of the working operation of the press upon completion of the weight compensating operation. The apparatus for carrying out the process includes at least one signal generator for providing an output indicative of the changing of a tool set, a device for preventing working operation of the press in response to the detection of such condition and a control arrangement for initiating operation of the weight compensating mechanism in accordance with sensed conditions of the press.

  • Patent number: 4011809
    Abstract: A press having mechanical drive elements acting on the ram through at least one pressure cushion serving as a hydraulic overload safety device, at least one cylinder-piston unit operating under the effect of a compressed fluid for counterbalancing the weight of the ram associated with an upper die of the press, and a control system for adjusting fluid pressure in the cylinder-piston unit to a value for counterbalancing the weight. The control system includes a pressure relief valve and a pressure meter associated with the pressure cushion wherein the meter detects the pressure in the pressure cushion in a measuring range including a predetermined value. An actuating member serves for initiating a counterbalancing operation which includes operation of the pressure relief valve and control of supply and discharge valves for supplying and discharging fluid to and/or from the cylinder-piston unit.

  • Patent number: 3982454
    Abstract: Apparatus for the control and regulation of the cutting interval for a strip advanced by a roll feed device and of the synchronism of a cutting mechanism effecting the cutting operation with the strip material during the cutting step. A common main drive serves for effecting movements of the cutting mechanism and of the strip material along its travel path and an auxiliary drive is effective on movements of one of the cutting mechanism and the strip material by way of a superposed gear system.
