Conveyor system and method for transferring stacks of paper or the like to a discharge conveyor
InactiveUS6942087B2Improve the conveyor system andGreat operating flexibilityFunction indicatorsCharge manipulationEngineeringPaper sheet
The conveyor system (11) is used for transferring rows or large cycles (66) of sheet stacks (12) from the stacking station (20) of a paper converting machine, e.g. a small format cross-cutter to several parallel-running discharge conveyor belts (24, 25). For this purpose grippers or tongs (48) are provided, which are guided on gripper supports (39) and which can draw the stacks (12) from stacking station (20) via conveyor belts (24, 25). For each stacking position (21) there are two grippers (48, 48a), which in each case alternatively grip and transfer a stack, whilst the other gripper performs the return movement and passes into its waiting position upstream of the stacking station.

Automatic music playing apparatus and computer program therefor
An external storage device stores automatic music playing data files, each file including data of a progression of musical notes constituting a performance of a music piece, and registration data files, each file including data of a set of parameters to determine the conditions for the performance of the music piece. While an automatic music playing data file of a piece of music and registration data files are loaded into a working memory and are being processed to play the current piece of music automatically, the next automatic music playing data file of the next piece of music to be played and the registration data files to be used next are prefetched from the external storage device into an internal storage device temporarily to be prepared for being transferred to the working memory for the successive automatic music playing after the automatic playing of the current music piece is over. Thus, dead time between the adjacent pieces of automatically played music and delay in effectuating the registrations will be avoided.
