A movable contact element for a pressing device for pressing meat products, in particular frozen and/or partly frozen meat products, preferably fresh meat products and/or bacon, comprises a base part; an attachment part; a transverse sliding part; and a height part that are connected to one another at respective connection points and that form a contact surface for a product at one side of the contact element during the pressing. The contact surface has an effective length along a first direction of extent and an effective width along a second direction of extent perpendicular to the first direction of extent, with the effective length and the effective width of the contact surface being variable.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

A work station for a packaging machine comprises a tool structure and a tool movable relative to the tool structure by means of a drive. The drive comprises at least one countermagnet which is operatively connectable to an electromagnet and movable relative to the electromagnet. The drive further comprises a mechanism by means of which the movement of the tool is unidirectionally coupled to the relative movement of the countermagnet relative to the electromagnet.

The present invention provides a linear motor device that can reduce a variation in thrust caused by a variation in attractive force. The linear motor device includes a linear motor 1 and a control section 30 that controls the linear motor 1. The linear motor 1 includes a magnet member 2 composed of permanent magnets having respective N poles and S poles alternately arranged in an axial direction, and a coil member 3 which is located orthogonally to the axial direction with respect to the magnet member 2 and through which the magnet member 2 is movable in the axial direction relative to the coil member 3. The control section 30 controls current conducted through the coil member 3 so that a moving one of the magnet member 2 and the coil member 3 reciprocates within a use range L corresponding to a part of a pitch p between the magnetic poles N and S in the magnet member 2.

The present invention provides a linear motor mounted press machine which uses a boosting mechanism to enable machining with a greater press tonnage using a press driving source with relatively low power and which, for machining with a smaller press tonnage, enables efficient high-speed machining. A linear motor mounted press machine includes a boosting mechanism 10 having an output portion that performs a rectilinear reciprocating operation, a first linear motor 11 coupled to an output portion of the boosting mechanism 10, a second linear motor 12 having an output shaft that drives a press tool 6 forward and backward, and a coupling switching mechanism 13. The coupling switching mechanism 13 releasably couples the output shaft of the second linear motor 12 to the output portion of the boosting mechanism 10. The boosting mechanism 10 is a toggle type link mechanism or the like. A servo motor and a crank mechanism or the like may be used in place of the first linear motor 11.

One of the key features of the present invention is the use of a electrical conduit arrangement that allows for the tailoring of the magnetic field so as to provide for the greater amount of force to be brought to bear generally in the center of the work force area. The present invention provides for such capability by providing for a single central current conduit for forming longitudinally extending work pieces. The present invention also provides for the splitting, and/or direction (or curvature) reversal, of the electrical current pulse one or more times to likewise tailor the magnetic field of the work-coil or forming actuator.

An electromagnetically-driven punch press having adjustable anti-skid supports for the ball bearings and ball cages of the ball-bearing bushings which carry the movable tool for preventing downward skidding of these balls and their cages when the moving tool punches down against the work material. Adjustable resilient cushioning arrests tool travel for minimizing "tool whip" and tool wear at the end of the work stroke.
摘要:
An electromagnetically-driven punch press has an electromagnetic drive thrust motor comprising a fan-cooled solenoid winding and movable armature mounted in elevated location for isolating the magnetic circuit from the tooling to avoid tool magnetization and isolating winding heat from tooling for stabilizing tool dimensions. Stroke length, "open" height and "shut" height are conveniently adjustable; and tool performance is optimized by adjusting armature-thrust versus travel. Four-way access to tooling enables convenient material feeding and handling, including multi-direction or multi-layer feed. Scrap pieces are freely downwardly ejected. Multiple electromagnetic drives are mountable side-by-side at the same elevation, or they are stackable at multiple levels for increased power or for tailoring force-versus-distance relative to materials being worked. Materials-handling and/or tool-handling robots or pneumatic actuators can be installed on an elevated platform. The electromagnetic drive is removable and interchangeable among multiple die sets for easy tooling change-over among various production runs. Thus, "tooling set-up" by skilled machinist need be performed only once for each die set until worn dies require sharpening. A resilient upwardly biased shuttle pole-piece boosts available energy by extending upwardly into the winding opening. Ball-bearing bushings carry the movable tool and anti-skid supports prevent ball bearings and their cages from skidding downwardly when the moving tool impacts against the work material. Adjustable resilient cushioning arrests tool travel for minimizing "tool whip" and tool wear at the end of the work stroke.
