  • Sample collator device with samples gathered on pins
    Patent number: 5181704
    Abstract: A carousel device for collating product samples includes pivoting arms provided with suction cups attached to the ends thereof that swing in a first direction toward adjacent bins until the cups contact and attach to samples stored in the bins. The arms then pivot in the reverse direction to a position in which a hole in the sample is engaged by a pin attached to one of a plurality of trolleys propelled around the carousel and past the arms by a moving chain. The vacuum is released as the trolleys move onward to another set of arms where an additional sample is placed on the pin. The process continues as the trolleys make a complete circuit of the carousel and collect a collated set of each of the samples contained in the bins.
