Voolikurullide mähkimine ja kinnitamine: lahendused tööstusele

Kokkuvõte

Hose coil wrapping and strapping starts with the coil itself: our automatic coiler counts the hose length, cuts it, winds it into a tight coil and straps it so it can be handled. This machine coils and straps; film wrapping, where needed, is a separate station downstream. The FCL range covers pipe OD from 4 to 63 mm, with coil OD up to 1,600 mm. A worked example sizes a 50 m coil of 32 mm double-wall corrugated hose.

Sisukord

Why corrugated hose is coiled and strapped

Double-wall corrugated hose and conduit leave the extruder as one endless length. Loose lengths kink, tangle and take floor space. A coil of fixed length, held by straps, stacks on a pallet and is easy to count at dispatch.

Hand coiling also caps the line speed. Once the extruder runs faster than two operators can wind, an automatic coiler takes over.

The yellow and white hose coiler

Our yellow and white coiler winds green corrugated hose onto a rotating former. A guide arm moves back and forth across the former, so each turn lies next to the one before it and the layers build evenly. When the coil is full the former stops and the operator steps in to check the finished coil. The control panel with its run and fault lamps sits at the side of the frame.

How one coil is made

The PLC runs the same sequence on every coil:

  1. Count. A meter counts the hose length as it enters the former.
  2. Tuul. The former turns while the guide arm traverses, laying the hose in even layers.
  3. Lõika. Määratud pikkuses lõigatakse voolik läbi.
  4. Rihm. The coil is tied at one or more points so it holds its shape.
  5. Tühjendamine. The coil is pushed or lifted off automatically and the former is ready for the next one. The operator only steps in for checks with the former stopped.

Coil length, number of straps and coil size are set in the PLC, so a size change is a recipe change plus the former setting.

FCL coiler data

Data from our hose coiling and strapping machine page for small pipe (FCL400 ID and OD as confirmed by our engineering team):

MUDEL torude OD coil ID Coil OD (max) Coil width (max)
FCL100 4–12 mm 150 mm 300 mm 150 mm
FCL200 8–28 mm 200–400 mm 650 mm 200 mm
FCL400 6–25 mm 300–500 mm 1,200 mm (OD range 680–1,200 mm) 250 mm
FCL600 8–28 mm 380–600 mm 1,050 mm 300 mm
FCL800 12–32 mm 490–860 mm 1,200 mm 350 mm
FCL1000 20–63 mm 600–1,300 mm 1,600 mm 400 mm

The larger models come with one or two coil heads. With two heads, one coil winds while the other is strapped and unloaded. For bigger pipe, the FPCL frames take 40–180 mm OD and coils up to 4,000 mm OD.

Worked example: 50 m of 32 mm hose

Illustrative order: double-wall corrugated hose, OD 32 mm, 50 m per coil, coil ID 600 mm, coil width 300 mm.

Mudel. 32 mm is the top of the FCL800 band (12–32 mm), and 600 mm ID sits inside 490–860 mm. Width 300 mm is under the 350 mm limit.

Pöördeid kihi kohta. 300 mm ÷ 32 mm ≈ 9 turns.

Length per layer. Each layer’s mean diameter is ID + OD × (2n − 1):

kiht Keskmine läbimõõt Length (9 turns × π × D) Jooksev kogusumma
1 632 mm 17.9 m 17.9 m
2 696 mm 19.7 m 37.6 m
3 760 mm 21.5 m 59.1 m

50 m ends in the third layer, so the coil OD is about 600 + 2 × 3 × 32 = 792 mm, well under the 1,200 mm FCL800 maximum.

Tsükkel. Winding time is coil length ÷ line speed. At a line speed of v m/min, one coil takes 50 ÷ v minutes. The cut, strap and discharge time has to fit inside that window on a single head. If it does not, we add an accumulator between the extruder and the coiler, or use a two-head coiler. We confirm the machine-side times at quote.

Kaasaost. Send the hose OD, the length per coil and the target ID and width. Corrugated hose packs less densely than smooth pipe, so we confirm the final OD with a trial wind.

Coiling, strapping and film wrapping

The coiler shown here coils and straps. Many hose makers stop there. Where the coil must stay clean, or is sold to retail, the strapped coil goes on to a hose coil wrapper that spirals stretch film through the eye. We build both stations and can link them with a conveyor, so one operator runs the whole cell.

Valiku kontroll-leht: mida meile saata

  1. Hose or pipe type (single or double wall), OD and material.
  2. Length per coil, coil ID and maximum width or OD.
  3. Number of straps and strap type (PP strap is common; tell us if you use another).
  4. Extruder line speed.
  5. Whether you also need film wrapping or labels.
  6. Destination country, for the CE file and voltage.

Ohutus: EN 415-10 ja ISO 12100

We build the coiler to EN 415-10 for packaging machines, with a risk assessment to ISO 12100. The main hazards are the turning former, the traversing guide arm, the cutter and the strapping head. Guard doors are interlocked, so the former stops when a door opens. Coil checks are made only with the former stopped, as the operator does once a coil is complete.

Inseneri KKK

Q: Does this machine wrap the coil in film? A: It coils and straps. Film wrapping is a separate station that we add after the coiler when you need it.

Q: Can one coiler run 8 mm and 50 mm hose? A: Not on one model. 8 mm sits in the FCL200 or FCL600 band and 50 mm in the FCL1000 band. A wide mix needs two machines or a custom frame.

Q: How exact is the coil length? A: The length counter stops and cuts the hose at the set length. The tolerance depends on the hose and line speed, and we confirm it at quote.

Q: Which standard do you use for CE? A: EN 415-10 with an ISO 12100 risk assessment.
