5-feed lidder for containers in various format
Machine frame made of robust, square-profile welded stainless steel tubing. Singling unit with five individual stations, at which lids are ACTIVELY separated. The lid stacks are conducted through hoppers made from Ø 15 mm round corrugated steel. Lids are gathered from five hopper stacks simultaneously. This is accomplished by vacuum suction using compressed air according to the injector principle. Vacuum cups are integrated in the required format. A horizontal pivot positions the separated lids over the sealed containers, a function accomplished via a powered servo motor unit which swivels through 140 °. The lids are then pneumatically pressed onto the available containers.
The sealed containers are continuously delivered to the lidder in an aligned orientation. The lidding station platforms are at the same height as the feeding conveyor belt. Format rings whose contour matches the sealed seam of the containers are mounted below the platforms. Once the containers are on the platform, they are lowered pneumatically via guide cylinders. The travel of the guide cylinder is deduced from the height of the container.
Pushing along the belt system towards the lidding station, and down again on the discharge conveyor belt, is achieved via motor-driven racks
The spacing between feed belt, lidding station and the discharge belt is 125 mm in each case (the cylinder travel).
The space between individual lidding stations is 150 mm
Control: Siemens S7, TIA Portal.
Cables and hoses in the mesh cable channel made from stainless steel.
Pneumatics are installed in a control cabinet underneath the machine.
Protective covers: robust, bevelled, laser-cut sections in a makrolon frame.
The protective covers are secured by magnetic switches.
The entire system can be moved along on four castors with brakes.
System length: approx. 1500 mm
System width: approx. 850 mm, plus approx. 150 mm hopper overhang
Total height: approx. 1,950 mm
