Shrnutí

Big hose, corrugated hose, wire-reinforced hose and HDPE pipe come off the extruder as one continuous length. An automatic coiling and strapping machine measures the length, winds it into a tight coil, cuts it and straps it, and a coil wrapper can then cover it in film. This page explains how the line runs, which coil sizes it handles, how many straps to use, and how to work out the length per coil.

The coiler combines a servo-driven expandable reel, a strapping head and an HMI panel on one frame. Red corrugated hose builds up on an expandable reel with steel spokes, and an orange strapping head waits beside the reel to strap the finished coil.

Aplikace

Produktový vývoj	Na čem záleží
Corrugated hose and conduit	springy, needs a reel that holds the shape until strapped
Hose with steel wire	stiff, needs more coiling torque and firm straps
HDPE, PERT, PEX and PE pipe	long lengths, tidy layers, cut to exact length
Garden and suction hose	consumer packs, often wrapped after strapping

How the line operates

Length set: the length per coil is entered on the HMI; an encoder measures the pipe as it runs.
Navíjení: the servo-driven reel winds the pipe in even layers, matched to the extruder speed.
Řezání: at the set length the pipe is cut and the tail held.
Otáčení: the coil is turned through 180° to the strapping position.
Páskování: 4 or 6 straps are applied around the coil.
Vykládka: the reel arms collapse and the coil is released.
Wrapping (option): the coil moves to an eye-through coil wrapper, where a film ring passes through the coil eye and covers the coil all round, over the straps.

Coil and pipe sizes

From our FCL-800 automatic pipe coiler:

Potrubní OD	ID Coil	Výška cívky	Coil OD
5 – 16 mm	200 – 300 mm	80 – 200 mm	500 – 800 mm
10 – 20 mm	250 – 500 mm	100 – 300 mm	500 – 800 mm
15 – 30 mm	300 – 600 mm	100 – 300 mm	500 – 800 mm

Coiling speed is up to 80 m per minute. Our HDPE coiler for 20–32 mm pipe runs on HMI, PLC, servo and encoder control at less than 3 kW, AC 220 V 50 Hz, with 0.5 MPa air at less than 1.0 m³/h, in a 4,500 × 2,200 × 2,100 mm footprint. Larger corrugated and wire hose is sized per project.

Length per coil

Turns per layer = coil height ÷ pipe OD. Layers = (coil OD − coil ID) ÷ 2 ÷ pipe OD. Length ≈ 3.14 × mean diameter × total turns. For 30 mm hose in a coil of ID 500, OD 800 and height 300 mm (example only):

Kontrola	Výpočet	Výsledek
Otáčky na vrstvu	300 ÷ 30	10
Vrstvy	(800 − 500) ÷ 2 ÷ 30	5
Celkový počet otáček	× 10 5	50
Délka	3.14 × 0.65 m × 50	o 102 m
Winding time at 80 m/min	102 ÷ 80	asi 1.3 min

Corrugated hose does not pack as tightly as smooth pipe, so check real length on a trial coil.

How many straps

4 straps: light, smooth coils that hold their shape.
6 straps: springy corrugated or heavy wire hose, and coils that are stacked high.

Strap material and tension are set to the hose, so the strap does not crush thin-wall corrugations.

Adding film wrapping

After strapping, a coil wrapping machine passes film through the coil eye and around it. Wrapping keeps out dust, holds labels and gives retail packs a clean finish. For pipe going straight to a building site, strapping alone is often enough.

Bezpečnost

The line is designed to EN ISO 12100:2010 for risk assessment, EN 415-10 for packaging machine safety and EN 60204-1 for electrical equipment. The turning reel, the cutter and the strapping head are the main hazards, so they are guarded with an emergency stop at the panel.

Často kladené otázky k inženýrství

Q: Can it coil corrugated hose? A: Yes. Coil size and strap count are set for the springiness of the hose.

Q: How fast does it coil? A: Up to 80 m per minute on the FCL-800.

Q: How many straps per coil? A: 4 for smooth coils that hold their shape, 6 for springy corrugated or heavy wire hose and for coils stacked high.

Q: Can it run online with the extruder? A: Yes, length is measured by encoder and coiling follows the line speed.
