  • the conveying device for the individual ammunition parts is implemented by means of a coherent conveyor chain, which basically moves the individual ammunition parts between the stations at a constant and equal conveying speed and comes to a standstill once per cycle.
  • the positioning with regard to the individual production stations occurs due to the arrangement of the holding device for the ammunition parts in the conveyor chain.
  • the connected conveyor chain only requires one positioning per cycle. However, this means that only a single cyclic movement profile can be processed, which means that all production stations have to be approached at the same time.
  • the proposed system must be aligned and calibrated very precisely, which makes operation susceptible to failure. Furthermore, the fixed and clearly defined arrangement of the processing stations increases the space required and the flexibility of the machine. This ultimately has a negative impact on the machine-dependent general manufacturing costs. There is also a need to process more ammunition parts in a shorter time (increase production capacity).
  • the speed of the conveyor chain can be increased in the known approach. However, due to the faster starting and stopping of the conveyor chain, the loads in the individual bearings increase disproportionately, which leads to increased wear on the machine, especially its moving parts. In addition, the faster movement of the conveyor chain increases the susceptibility of the entire system to errors in terms of feeding, which leads to increased rejects. This reduces overall plant effectiveness despite higher production capacity.

According to the invention, a high degree of flexibility is achieved in a simple manner by means of the movable mounting of the ammunition part holder relative to the carrier base. Due to the movability of the material holder, it is possible to bring it into the optimal orientation during the different processing steps or in the different processing stations.
