Mechanický naklápěč cívek s přizpůsobeným servisem

Shrnutí

A mechanical coil tilter (coil upender) reorients heavy wire or slit coils between vertical (eye-to-sky) and horizontal (eye-to-wall) orientations using a rigid electromechanical gear-drive instead of hydraulic cylinders. Powered by an inverter-controlled motor and a self-locking worm reduction mechanism, the machine eliminates oil leakage hazards and resists gravitational back-driving during mid-cycle power disruptions. While standard FPCT models handle rated capacities from 3 t to 10 t, engineering customization adapts the V-deck cradles, contact linings, drive capacities, and conveying automation directly to your plant geometry and coil dimensions.

A standard off-the-shelf tilter handles regular master coils, but non-standard package dimensions, slit coils on pallets, finished copper coils with delicate surfaces, and automated packing cell interfaces demand bespoke engineering. Designing the machine around actual coil parameters ensures load stability and continuous cycle safety across all operations.

Proč mechanický pohon

Industrial heavy-duty coil tilting typically relies on either electromechanical gearing or hydraulic power units. Mechanical drive units offer distinct operational benefits for clean manufacturing and continuous handling lines:

  • Inherently self-locking mechanics: The drive unit integrates a high-efficiency motor paired with a heavy-duty helical-worm reducer. Due to the lead angle characteristics of the worm gearing, the drive mechanism physically resists back-driving. In the event of a total line electrical failure, the cradle remains securely locked at its instantaneous angle without mechanical drift.
  • Fail-safe dynamic braking: The system utilizes an electromagnetic motor brake arrangement configured for asymmetric and eccentric load profiles, ensuring positive positioning across 0° to 90° transitions.
  • Elimination of hydraulic failure points: Without hydraulic pumps, valves, cylinders, or high-pressure flexible hoses, facilities avoid oil leakage risks, seasonal viscosity fluctuations, fluid disposal costs, and routine seal replacements. This makes mechanical tilting ideal for paper, film, and high-purity metal facilities.
  • Smooth velocity profiles: Variable Frequency Drive (VFD) inverter control modulates motor acceleration and deceleration ramps. This provides soft-start and soft-stop kinetics that minimize structural shock on the machine base and eliminate slip marking on wrapped products.

Standardní modely mechanických naklápěčů cívek

The standard FPCT series provides verified structural frames for standard industrial loads. Custom-engineered machinery uses these field-proven platforms as base kinematic envelopes:

Model Maximální kapacita výkon motoru Operating speed (90° cycle) napájení
FPCT-03 3 t 1.3 kW 50–90 s AC 380V / 50Hz (or custom)
FPCT-05 5 t 2.0 kW 50–90 s AC 380V / 50Hz (or custom)
FPCT-10 10 t 2.5 kW 60–90 s AC 380V / 50Hz (or custom)

Note: Drive motor power and cycle profiles correspond directly to rated maximum loads. Working platform dimensions, clearance radius, and reinforced substructures are adapted to specific coil OD, ID, and axial width requirements.

Co přizpůsobujeme

Customized service bridges the standard mechanical frame and the site’s handling reality:

  • Cradle and platform: symmetrical 90° V-deck for cylindrical coils, or asymmetric decks (flat side for palletised coils, V-deck for bare slit coils). PU or cast-nylon wear pads protect coated, polished or wrapped surfaces.
  • Turning geometry: 90° upending as standard, or continuous 180° rollover frames for mould and die work.
  • Infeed and outfeed: flat base for forklift loading, counterbalanced cutouts for crane C-hooks or coil grabs, or motorised rollers and walking-beam tables built into the platform.
  • Ovládání: standalone push-button console with dual-hand control, or PLC integration with a fieldbus handshake for automated lines.
  • Stopa: low-profile frame for surface mounting without a civil pit, or a reinforced frame for an existing pit.

Jak funguje přizpůsobený design

Custom machines are developed through a fixed sequence:

  1. Sběr dat: you send coil weight, OD/ID/width ranges, turn direction and floor plan constraints.
  2. Velikost: engineers calculate the centre of gravity through the turn, pick the base frame (FPCT-03, FPCT-05 or FPCT-10) and set the reduction gearing.
  3. Drawing approval: a 2D general arrangement and 3D model show platform cutouts, crane clearances, anchor points and electrical ratings.
  4. Build and load test: the frame is welded and machined, then tested at full load with brake-stop checks under an unbalanced load.
  5. Odeslání: the machine ships assembled with maintenance manuals and electrical schematics.

To ensure exact mechanical and drive sizing for your inquiry, compile the following specifications:

Safety engineering: EN 415-10 and ISO 12100

Heavy coil handling introduces extreme mechanical inertia risks during rotational reorientation. When integrated into packaging and handling lines, our coil tilters comply with European standard EN-415 10 (Safety of packaging machines: General requirements), with systematic risk reduction designed under ISO 12100 zásady:

  • Redundant motion limiting: Heavy-duty electromechanical limit switches backed by rigid physical displacement hard stops limit cradle movement to exactly 90°.
  • Anti-drop integrity: Geared worm drives prevent sudden back-driving during emergency stops or supply drop-outs.
  • Control reliability: emergency-stop circuits drop motor power through redundant contactors; perimeter fencing, sensing devices and floor mats are specified by the cell hazard evaluation.
  • Kontroly kvality: machines are built under the manufacturer’s ISO 9001 quality system, with CE marking where the destination market requires it.

Často kladené otázky k inženýrství

Q: When should an engineer specify a mechanical tilter over a hydraulic tilter? A: Mechanical tilters are preferred for capacities up to 10 t where clean operation is required (avoiding oil leak risks near wrapped goods or clean production floors) and where cycle repeatability, low cold-weather maintenance, and electrical self-locking are essential. Hydraulic tilters are typically reserved for extreme capacities above 20 t.

Q: How does the mechanical unit maintain position during an electrical blackout? A: Safety is ensured via mechanical worm gearing that naturally resists counter-rotation under reverse torque, combined with a spring-actuated, power-off dynamic brake fitted to the motor shaft.

Q: Can platforms be designed to handle both strapped master coils and palletized cut coils? A: Yes. We regularly supply combined deck platforms featuring a 90° V-profile on one face to centralize round coils, and a reinforced flat deck on the perpendicular face to hold pallets without damaging wood runners.

Q: What standard warranty covers the equipment? A: Machines are supported by a two-year structural and mechanical drive warranty.
