Abstract: A packaging machine having at least one working component that is mounted in an adjustable manner relative to a machine frame between a first and a second position, and that incorporates at least one pneumatic unit. A coupling member may be mounted in a tiltable manner relative to an axis, and in one embodiment, the coupling member may connect the pneumatic unit to the working component. The coupling member may be arranged at least in part within a piston of the pneumatic unit and may be mounted in a linearly adjustable manner along the axis.

Abstract: According to various embodiments, the present teachings relate to an alignment device, method, and system for aligning an upper platen of a paperboard press with a lower platen of a paperboard press. The alignment device can comprise a latching collar adapted to be mounted on a lower platen. The latching collar can comprise a central hole and can be adapted to be mounted on or affixed to the lower platen. The latching collar can comprise a locking area. The alignment device can further comprise a plunger unit. The plunger unit can comprise a housing, a securing device attached to the housing, and a plunger configured for reciprocal motion through the housing. The securing device can be adapted to removably secure the housing to a top surface of an upper platen of a paperboard press.

Abstract: A slide of a press machine is driven by composite thrust of thrust of an electric (servo) motor SM (via a screw/nut mechanism from the electric motor) and thrust of hydraulic cylinders SYL1, SYL2 to which pressure oil is supplied from a constant, high pressure source. A slide control device controls the electric motor SM and the hydraulic cylinders SYL1, SYL2, based on a slide position signal and a motor angular velocity signal, and at the same time, makes the hydraulic cylinder SYL1 work as a pump during a period when slide load is small, charging pressure oil to the constant, high pressure source by using the thrust transferred from the electric motor to the hydraulic cylinder SYL1 through the screw/nut mechanism and the slide.

Abstract: The present invention relates to a compress and position apparatus with positioning, orientating functions and providing more uniform pressing force compliantly. The compress and position apparatus comprises a guiding column, a base, a housing, a seat, a annular portion and a pressing plate. The base has a cylinder, a plurality of locating pins and a convex portion. The annular portion has a through hole and a plurality of locating holes. The guiding column and the cylinder are disposed in the housing provided with an opening for the guiding column passing therethrough. The housing is mounted on the base and passed through a through hole of the annular portion and disposed in a cavity of the seat. A plane on the housing abuts a plane on the cavity to prevent the rotation of the housing. The guiding column is combined with the seat. The locating pin is inserted into the locating hole. The pressing plate engages the annular portion. Thus the guiding column is moved up and down by the gas supply device.

Abstract: A rod pressure holding instruction section controls a servo motor to rotate a two-way pump in a counter direction, and to supply hydraulic oil, with pressure which does not exceed pressure from a weight of a ram, to a two-way pump-side piping, increasing pressure. A difference between pressure in a rod-side cylinder chamber-side piping of a speed switching valve and pressure in a two-way pump-side piping of the speed switching valve is decreased, thereby decreasing an impact generated when switching the speed switching valve and stopping the ram at a predetermined position.
