Title: Sheet discharge device of rotary print-folding machine
Inventor: ABE KATSUHITO
IPC: B65H29/60
Filed: 1991-09-30
Abstract: PURPOSE:To provide a sheet discharge device of a rotary printfolding machine capable of switching a transport path for a folded sheet in a single action and thereby, simplifies an operation and prevents a faulty action from occurring. CONSTITUTION:The elevation of a shaft 16 to be set by the vertical movement of an am 20 is converted to a rotary motion of a shaft 16 required for the parking and storage of a stopper 15. The subject device is composed mainly of a lever 30, a rotary cylinder 31 and a fixed pin 32. The vertical movement of the arm 20 results in an elevation difference between the fixed pin 32 and the shaft 16, and the lever 30 slides in the interior of a rotary cylinder 31 centered around the fixed pin 32, rotating the shaft 16 fixed by a clamp bolt 33 to the shaft 16. Thus the stopper 15 protrudes from a transport part and becomes parked from the path. Subsequently, the frequency of manual operation is reduced and the operating efficiency is increased. In addition, the failure to operate the stopper no longer occurs and the disorder of the device due to a faulty operation can be prevented from occurring.

Filed: 1993-09-13
Abstract: PURPOSE:To obtain the positioning accuracy which surpasses the working accuracy of V-grooves and core pins by holding the core pins with the V-grooves molded in a lower metal mold and the plane of an upper metal mold and clamping the upper and lower metal molds to each other to cause slight deformation with each other. CONSTITUTION:The core pins 3a to 3d are placed in the V-grooves 21 of the lower metal mold 2 and the upper metal mold 1 is mated thereon from above. While spacings C1, C4 of 3a, 3d making three-point contact are zero, there are spacings C2, C3 respectively in the core pins 3b, 3c. The core pins 3a to 3d are deformed with each other by the pin contact planes of the V-grooves 21 and the metal mold 1 and all the spacings are made zero, i.e., a state approximate to tight contact if the spacings CA, CB of the upper and lower metal molds are made zero by clamping the upper metal mold 1. The deformation is confined within the elastic threshold in Hertz contact, i.e., within a size range where the core pins completely restore the original shape when the metal molds are opened after mold clamping. The absorption of the errors in the diameters of the core pins and the sizes of the V-grooves is possible according to this method.
