  • Patent number: 9643232
    Abstract: A servo press line operation method operates a servo press line in which a servo press and a servo transfer device are disposed in a workpiece transfer direction. The servo press line operation method includes causing a transfer controller to receive a master signal that causes the servo transfer device to make a motion in synchronization with the servo press, the transfer controller controlling a motor of the servo transfer device using a motor instruction, causing the transfer controller to determine whether or not an abnormality in the master signal has occurred, and causing the transfer controller to generate the motor instruction based on a stop signal that stops the motor of the servo transfer device, instead of the master signal, when the transfer controller has determined that an abnormality in the master signal has occurred.

  • Patent number: 9426113
    Abstract: A device can process commands from a remote device that manages the local device over a content centric network. During operation, the device can receive an Interest for managing a device resource, such that the Interest's name includes a name or a name prefix associated with the device resource, and includes a command for managing the resource. If the device determines that the name prefix corresponds to the local device, the device analyzes the Interest's command to determine a device resource and performs the resource-managing operation on the device resource. If the name prefix does not correspond to the local device, the device performs a longest-prefix-matching lookup using the Interest's name prefix to determine a destination for the Interest. If the Interest's destination corresponds to a component of the local device, the device forwards the Interest to the component or a local agent for the component.

  • Patent number: 8074810
    Abstract: Apparatus and methods provide individual blades driven by drives configured to reduce a tendency of sludge to be moved in an undesired return direction. Drive configurations apply “pull” and “pull” forces that only pull on tensile structures, avoiding a need in actual commercial practice for use of extra structural drive members having high resistance to both tension and compressive forces exerted parallel to a sludge movement direction. Each of two separate tensile structures carries one blade, or a separate set of blades, with blade(s) of one structure adjacent to, and alternating with, blade(s) of the other structure. Embodiments move sludge from a corner of a basin and across a floor of the basin. The reduced tendency of sludge movement in the return direction results from moving one tensile structure and blade(s) in the sludge movement direction as the other tensile structure and adjacent opposed blade(s) move in the return direction.

  • Patent number: 7159438
    Abstract: A transfer press provided with a transfer device, having transfer units provided with cross members (37) for which the length is shorter than the width of a tool. The transfer units (29 to 32) are arranged completely between the processing stations or stages, are mounted on the crown or head piece, and are not provided with elements extending beside the tools or between supports of adjacent processing or press stations. Thus, the full width spanned by the press supports can be used for the tools. In addition, tools can be used which are provided with guides, effective between the upper tool and the lower tool, particularly in the side region. The work pieces are handled solely by means of the openings, freed by the tools and pointing counter to the transporting device, wherein no element of the transfer device extends past the side limits of the tool.

  • Patent number: 7051864
    Abstract: A roller-guided feeding device includes guiding rollers, an arm which is movable relative to the guiding rollers between initial and working position that are remote from and closer to the guiding rollers, respectively, and which has a feed-in roller, a pneumatic cylinder, and a piston rod connected to a piston in the cylinder. The piston rod is moved as a result of a difference in pressures in the cylinder so as to turn the arm. A servo valve member is disposed to control air flow into the cylinder so as to hold the feed-in roller at the working position and the initial position in response to a work signal from a sensor member and a start signal from a manually-operated actuator, respectively. In response to a pausing signal from the sensor member, the feed-in roller is held at a pausing position to serve as another initial position in a subsequent cutting operation.

  • Patent number: 6729617
    Abstract: A device for conveying flat objects in series and edge-on, in which the flat objects (12) are moved in a conveying direction (D), while at the same time being separated each from the next by a spacing which is normally constant, has a synchronization system (2) capable of compensating for any variations in spacing between two consecutive objects. The system includes two parallel rows (3, 4) of driven wheels (3A-4C) made of elastically deformable elastomer and between which each object is gripped and moved in the conveying direction. Each wheel has a rotation spindle (6), the position of which is fixed, and the wheels are rotated by a motorization system which is controlled to accelerate and/or retard the movement of each object between the two rows of wheels on the basis of a detection whether the front edge of the object has been early or late in passing a determined position upstream of the two rows of wheels compared with a time reference indicating the spacing between objects.

  • Patent number: 6701769
    Abstract: Short lift beam is employed for each transfer area, the lift beam is driven by a compact servomotor for transferring the workpieces, and the carrier is driven by the linear motor being integral therewith. Therefore, consumption of electric power can be reduced significantly, thereby promoting energy saving. The control may be performed depending on the die employed in each workstation by controlling the motion of the lift beam or the carrier at each transfer area arbitrarily by the controller. Consequently, drive with interference between the workpieces and the dies eliminated can be realized irrespective of the size or other element of the dies, thereby increasing design freedom of the die.
