תחנת רולר לאריזת סלילים גדולים עם כיסוי ורצועות פלדה

תקציר מנהלים Big export coils are often too large or too few to justify a full automatic packing line. A roller station turns the coil on two driven rollers so a small crew can cover and strap it in one place. On the station in our video, the crew wraps the coil in protective material, covers its outside with a לוח מתכת ו רצועות the pack together. The station replaces crane turning between steps, which is the slow and risky part of manual coil packing.

מה עושה תחנת הגלילים

We build the station as a heavy base with two parallel coil turning rollers, and the coil lies eye-horizontal across them. When the rollers turn, the coil turns with them, so every part of its outside comes round to the packer.

The crew turns the coil in short steps, so it stops where the next joint or strap goes. That one motion does the job a crane would otherwise do several times per coil: turning the coil to reach the next section of wrap, the next sheet joint or the next strap position.

Because the coil only rolls in place, it never leaves the station during packing. It arrives by crane or coil car, is packed, and leaves fully strapped.

The packing sequence

Our video shows the whole packing process on one station:

שלב מה קורה למה
1 Coil set on the rollers One handling move in, none during packing
2 Protective wrap around the coil Keeps moisture and dirt off the steel surface
3 Steel sheet covering around the outside Takes knocks from slings, forks and other coils
4 חָסוּן וְגָבוֹהָ Holds the cover tight and keeps the coil from opening
5 Coil lifted off Packed coil goes to storage or loading

The rollers turn the coil between steps 2 and 4, so the crew works from one side of the station. The protective layer goes on first because it must sit directly on the steel; the sheet goes over it, and the straps go over both.

Why a steel sheet cover

Film and paper protect the surface but not the shape. A big coil is lifted by sling or C-hook, set down on hard floors and stowed against other coils in a ship’s hold. Each contact concentrates on the outer laps, and a dented outer lap is scrap for the customer.

A steel sheet wrapped around the outside spreads those contacts over a wide area and stops them reaching the coil. The straps then pull the sheet tight against the protective wrap, so the cover cannot slide or flap open in transit.

Cutting sheet and straps to length

The crew cuts the sheet and straps before the coil arrives, so the lengths are worth working out once per coil size. Illustrative example for a coil of 1,800 mm OD, 610 mm ID and 1,500 mm width:

פריט נוסחה ערך
Outer circumference π × OD על XNXX m
Steel sheet length Circumference + overlap at the joint about 5.65 m plus overlap
Circumferential strap π × OD + joint allowance about 5.65 m plus joint
Radial strap through the eye 2 × width + (OD − ID) + joint allowance about 4.19 m plus joint

Radial straps run through the eye and around the coil wall, so they hold the laps together. Circumferential straps run around the outside and hold the sheet cover closed. A heavy export coil usually gets both.

Roller station or packing line

בחרו מתי
תחנת רולר Few big coils per shift, many sizes, export packs with steel sheet covers
קו אריזה אוטומטי Steady coil flow, repeat sizes, wrapping and strapping done by machine

A roller station is a low-cost start: it removes the crane from the packing steps without changing how the crew packs. When the coil count grows, the same coil sizes can move to an automatic line with an orbital wrapper, strapping machine and downender.

Safety on a roller station

The danger points are the nips where the coil meets the rollers, and the coil itself if it rolls off. Keep hands and tools away from the roller nips while the coil turns, and stop the rollers before fitting a strap. The coil must sit centred between the rollers, so that its weight stays between them.

התקנים החלים תלויים בשוק היעד. עבור שווקי CE, ISO 12100 קובע את שיטת הערכת הסיכונים ו-EN 415-10 קובע דרישות כלליות למכונות אריזה.

Selection checklist for a coil roller station

  • Heaviest coil and its OD, ID and width.
  • סלילים למשמרת.
  • Pack spec: protective wrap, steel sheet cover, edge protection.
  • Radial and circumferential straps per coil.
  • How coils arrive and leave: crane or coil car.
  • Floor space around the station for the crew.
  • Later move to an automatic line, if planned.

שאלות נפוצות בנושא הנדסה

Q: What does a roller station do in coil packing? A: It turns the coil on two rollers so the crew can wrap, cover and strap it without a crane turning it between steps.

Q: Why cover a coil with steel sheet? A: The sheet spreads knocks from slings, forks and other coils, so the outer laps are not dented in transit.

Q: How long should the steel sheet be? A: The coil circumference, π × OD, plus an overlap at the joint. A 1,800 mm OD coil needs about 5.65 m plus overlap.

Q: Which straps go on a big coil? A: Radial straps through the eye hold the laps together, and circumferential straps hold the sheet cover closed.

Q: When should I move to an automatic line? A: When coil flow is steady and sizes repeat, so wrapping and strapping can be done by machine.
