Handling systems for the paper industry
Paper handling lines move reels between receiving, production, storage and dispatch. FIMEC SH integrates conveyors, shuttles and gantries with weighing, dimensional inspection and packaging stations.
Reel infeed: diameter
600 to 1,500 mm
Reel infeed: length
1,800 to 2,050 mm
Reel infeed: weight
4 t maximum
Measuring gantry: weighing
Accuracy ±1 kg, subject to measurement conditions
Measuring gantry: diameter
Accuracy ±2 mm, subject to measurement conditions
The reel path through the line
At the infeed, an automatically guided shuttle receives the reel. The placement and weighing gantry checks weight and dimensions before subsequent operations. Conveyors and shuttles connect the stations to storage areas.
A parent reel, a group of smaller reels and a wrapped load have different handling requirements. Each station therefore has its own specifications: the smaller-reel transfer gantry does not share the weighing gantry’s load capacity.
Line functions
Unwrapping: rotation angles
90° and 180°
Unwrapping: rotation time
25 s for 90°
Support rollers
Reel rotation: 10 rpm
Smaller reels: diameter
300 to 1,300 mm
Smaller reels: height
55 to 1,200 mm
Transfer gantry: load
1,500 kg
Transfer gantry: travel speed
50 m/min
Transfer gantry: lifting speed
15 m/min
The infeed and unwrapping stations handle reels from 600 to 1,500 mm in diameter, 1,800 to 2,050 mm long and up to 4 t in the illustrated application.
At unwrapping, the table turns the reel through 90° or 180°. A 90° movement takes 25 s; rotation of the reel on its support rollers is a separate function, rated at 10 rpm.
The stacker crane handles reel entry into and retrieval from the store. For groups of smaller reels, the gantry lifts the load from underneath and holds it during transfer to limit tipping.
Both gantry examples, transfer and placement-weighing, are also described on the handling gantry equipment page.
The wrapper applies film axially and radially, with protection for the reel sides and edges. Labels are applied to the film or inserted beneath its final layers. The reel upender and accumulation conveyor organise discharge.
The tables distinguish the stations in the paper handling application. Weight and diameter accuracy figures relate to the measuring gantry; validation depends on the product and measurement conditions.

Equipment
Industrial handling gantries
The handling gantry picks up a load, transfers it and places it at the required station. FIMEC SH engineers the gripping arrangement, travel distances and movement sequence around product geometry and installation constraints.
