Abstract: The present disclosure concerns a jam detection and safety system for machines prone to jamming, such as a baler. In particular embodiments, the system is implemented in a horizontal baler having a shear bar and a hydraulic ram that advances material being baled past the shear bar into a compression chamber. The system includes a strain gage mounted on the shear bar and a controller that is electrically connected to the strain gage. The controller receives strain signals from the stage gage and compares the strain of the shear bar to a predetermined strain threshold corresponding to a jamming condition. If the strain exceeds the predetermined threshold, the controller automatically deactivates the ram, such as by disconnecting line power from the baler and/or by turning off the control power of the baler.

Furthermore, there is a control unit which stops the working movement in response to the first light barriers. There is also a configuration device, by means of which selected ones from the first light barriers can be deactivated at least for the duration of the working movement.

Abstract: A manually operable press comprises a manually pivotable actuating lever for effecting a forward press stroke and a return stroke of a press slide. A mechanical return stroke interlock inhibits a return movement of the press before the press slide has come to a lower end position of the press stroke. A cam plate within said return stroke interlock is connected for being pivoted together with the actuating lever. The cam plate has a groove-shaped guide cam provided with a plurality of lock protrusions. A spring-biased lock pin runs along the guide cam and is adapted to run freely along the guide ram in an operational direction but is inhibited by the lock protrusions within the guide cam from running in a direction opposite the operational direction. An opening each is provided in the guide cam at the lock protrusions. Unlocking pins are provided in each of the openings.

Abstract: There is disclosed a baler for paper recycling having a control system responsive to switches and digital timers, and an electromagnetic interlock coupling a loading door and a chamber door, said control system including a programmable relay having outputs to motor starter, control valves, and electromagnetic interlock. A mode selection switch enables automatic, manual down, and manual up modes, the latter of which is used to eject a bale. The electromagnetic interlock performs multiple functions reducing the number of components needed in the system, improving reliability and reducing maintenance.

Abstract: A punch and press system includes a low voltage safety circuit and a high voltage control circuit. The high voltage control circuit is further divided into a high voltage low current region and a high voltage high current region. The high voltage low current region is isolated from both the low voltage safety circuit and the high voltage high current region of the control circuit. As the upper tool of the press strikes an object, the object's conductivity will govern whether the press will continue to act on the object. Thus, if the object is conductive, then the upper tool will continue to act on the object. If the object is not conductive, then the upper tool will raise to a neutral position.

In all embodiments, the rotation of the shaft carrying the flywheel due to the inertia of the flywheel is ineffective for driving the plunger and auxiliary function drive arrangements when power to the main drive shaft is cut off.
