A press machine includes a first rotary shaft which rotates in synchronism with a press crankshaft, a second rotary shaft which is coaxial with the first shaft and which has a drive cam for actuating a knock-out pin, and a clutch for connecting and disconnecting the first and second shafts. Knock-out timing is adjusted by releasing the clutch to separate the shafts and rotating one of the shafts through a predetermined angle relative to the other to produce a predetermined rotational phase difference between them. In the preferred embodiments, the second shaft is axially aligned with the first shaft, and is rotatable but axially immovable with respect to the press frame. A driving gear and a driven gear are provided between adjacent portions of the first and second shafts. The second shaft has a bore in which a lightweight, axially movable shaft is mounted. This movable shaft carries at one end a connector gear which is engageable with the driving and driven gears between the first and second shafts and which, together with the driving and driven gears form the clutch. A connector is provided for engaging the clutch and a separator is provided for disengaging clutch. The first and second shafts are separated by displacing the movable shaft and the connecting gear therewith with the use of the separator to disconnect the driving gear from the driven gear.

A pressure transducer which produces an output capacitance signal which is unaffected by temperature or mechanical distortion. A sensing chamber is provided at the center of a pressure sensor body with the sensing chamber being filled with a sealed liquid. A moving electrode of a cantilever structure is disposed in the sensing chamber and a through hole extends from the sensing chamber to at least one side of the pressure sensor body. A pressure receiving element is disposed on at least one side of the pressure sensor body and a rod couples the pressure receiving element and the moving electrode through the through hole. Two fixed electrodes of a cantilever structure are disposed opposite the moving electrode to form first and second variable capacitance elements together with the moving electrode.

摘要:
A device for controlling the interval between articles on a belt conveyer which includes forming the conveyer with a plurality of spaced belts, gates beneath the belts and movable upwardly between the belts and a control device for controlling the gates to regulate the intervals between articles carried by the conveyer. gates lift the articles from the belts and periodically redeposit them on the belts in response to a signal generator resulting in the release of uniformly spaced articles. The circuit further includes an article sensor for each gate and a further emergency sensor detecting an additional article when the system is already filled to capacity causing interruption of the motion of the belts.
