Conveying System between two Machining Processes

MTF Technik - Conveying System between two Machining Processes

Task: Reliable conveying of sensitive plastic parts between processing steps

  • Bullet casings have to be taken from plastic containers to a bunker and feeded to a production machine tailored to demand. The capacity of the bunker has to be 300l

  • Approx. 250 bullet casings have to be processed per minute

  • The production machine is equipped with two centrifugal feeders. Sensors on site detect the filling level. The feeding corresponds to demand

  • After the first production machine the bullit casings shall be feeded to a second machine, optionally they shall be distributed to buffer containers

  • The transport has to be carried out gently: the parts must not be damaged. A dead-lock has to be avoided

  • Interfaces to the production machines have to be processed by the control

  • Since there is lack of space at the machines, passages for the staff has to be available

  • Highest process reliability is important, i.e. no bullet casing may remain on the belts when the batch is changed. The presence of containers has to be detected, a change of container has to confirmed, etc.

Solution: Protected conveyor belt combination with switch and distributor

  • Combination of a GL-conveyor with big stainless steel hopper and a PL-conveyor equippped with a pneumatic junction plate to divide the flow rate to the circular feeders

  • ZL-conveyor with a fixed 75° angle right after the first production machine, equipped with a chute to pass on to a rounder. This chute consists of a special stainless noise suppression sheet with integrated cascades to reduce fall velocity

  • Rounder with polycarbonate cover to direct the parts optionally into the hopper of the second production machine or into the containers

  • The PL und ZL-conveyors are equipped with a hard-wearing polyester belt (MTF-belt no. 12) with extra large cleats. The belt is guided in order to reduce the gap between guiding profile and end of cleat to a minimum

  • The guiding profiles of the conveyors are completely covered with stainless steel. The punts are welded and trimmed to avoid any hems

  • Complex control (model: VIPA, similar to Siemens S7), to control the complete system including the interfaces to the production machines

  • The steep parts of the belts are covered with flexible material above the cleats in order to avoid a backslide of parts

  • All conveyors have a top cover made of polycarbonate
