Syringe-Feeder: Function

As fundamental basis there are two possibilities:
a) The hanging disposable syringes come directly from the assembling line. Via 2 parallel running conveying belts they are transported into a magazine of the basic feeder

b) The disposable syringes to be packed are fed into the storage hopper manually. Via a conveying belt, the syringes get transferred into a centrifuge, where after they will be separated and fed into 2 rotating shafts which brings them into a hanging position and gives them to 2 parallel running conveying belts. They transport the syringes into a magazine of the basic feeder.

The syringes are taken out of this magazine by a link chain. This link chain is specially dimensioned to allow accurate loading of the syringes as this corresponds to the distance of the formed packages in the packing machine. The conveying belts and the magazine are also designed to operate as a buffer, they supervise that at all times enough syringes are in store for one cycle of the link chain.
Corresponding with being loaded out of the magazine, the syringes are counted and if necessary checked for missing needles and their protection caps. When all syringes with needles are present, the suction arm which is located above the syringes, comes down, sucks them up, lifts, swivels around over the forms, lowers and interrupts the vacuum for unloading. At this moment, the opposite suction arm is now in position and ready for the next cycle to begin.
Adjacent to the swivelling, the link chain is brought forward, releasing the appropriate number of syringes for the next cycle.
Should one of the needles or one of the protection caps be missing, the swivel arm is blocked and a new impulse is given to the link chain which will execute this cycle and reloads again. This ensures that only the complete syringes are transported to the packing machine. An "attendance control" at this point is therefore not required.
