תקציר מנהלים Our aluminum profile wrapping line feeds timber spacer blocks to the top and bottom of each bundle, then spiral wraps the bundle with stretch film. The PLC sets the number of blocks from the bundle length. The line takes bundles from 70 to 300 mm high, 450 mm wide and 5,650 to 6,500 mm long, and one operator feeds the profiles.

איך הקו עובד

In this video, our line wraps flat aluminum profile bundles in blue stretch film. The bundles run on a conveyor through the ring of the horizontal wrapper. The line has three stations:

Infeed roller table. Powered rollers carry the bundle. Centering rollers keep the profiles in the middle of the table before the wrapper.
Spacer feeder. The feeder places timber blocks on the top and bottom of the bundle. Photocells detect the bundle, and the PLC controls each step.
Spiral wrapper. The ring starts automatically and wraps the bundle and blocks together with stretch film.

Bundle size window

פרמטר	טווח
גובה הצרור	70–300 מ"מ
רוחב הצרור	450 mm (specified width for this line)
אורך החבילה	5,650–6,500 מ"מ

We build three standard lengths: 5,650 mm, 6,000 mm and 6,500 mm. The top feeding height adjusts to the bundle height. The rollers in the wrapper open and close automatically, so bundles of different sizes pass through without stopping the machine.

Planning the spacer blocks

The blocks keep space between stacked bundles for forklift tines and slings, and protect the profiles. The PLC sets the number of blocks from the selected bundle length and the set block quantity. A simple way to plan:

Choose the spacing. For example, an illustrative spacing of 1,500 mm.
Count the positions. For a 6,000 mm bundle: 6,000 ÷ 1,500 + 1 = 5 positions along the length.
Count the blocks. With blocks on the top and bottom, that is 5 × 2 = 10 blocks per bundle.

The blocks are stored at the side of the machine and fed automatically. An automatic device integrated with the wrapper applies blocks under the bundle during wrapping, at the final stage. The finished bundle is stable and compact.

Wrapping the bundle

סרט צילום. The spiral wrapper uses 25 micron stretch film.
חומרים. Our aluminum wrappers can also apply PE, knit belt or VCI paper.
חֲפִיפָה. Adjustable from 10% to 90%, to save material or seal the pack.
Speeds. Inverters change the wrapping and conveying speed. The ring runs at 30–60 r/min.
גְזִירָה. The blade cuts the material at the end of each cycle.
Fault stop. If the film tears, the machine stops and alarms.

Changing a film roll takes less than one minute.

Ring speed, line speed and overlap

The bundle moves through the ring while the ring turns. How far it moves in one turn sets the overlap. Our aluminum wrapper has a wrapping speed of 2–16 m/min and a ring speed of 30–60 r/min:

Fastest setting. At 16 m/min and 60 r/min, the bundle moves 16,000 ÷ 60 = about 267 mm per turn.
Slowest setting. At 2 m/min and 30 r/min, it moves 2,000 ÷ 30 = about 67 mm per turn.

Compare this advance with the width of your film on the bundle. If the advance is close to the film width, the overlap is low. For a high overlap, we run a slower line speed or a faster ring. We set both with you from your film, the overlap you need and your bundles per hour.

שאלות נפוצות בנושא הנדסה

Q: What bundle sizes does the line take? A: 70–300 mm high, 450 mm wide and 5,650–6,500 mm long.

Q: How many spacer blocks does a bundle get? A: The PLC sets it from the bundle length and the block quantity you choose. At an illustrative 1,500 mm spacing, a 6,000 mm bundle gets 10 blocks, top and bottom.

Q: Does the feeder place blocks under the bundle too? A: Yes. Blocks go on the top and bottom, and a device integrated with the wrapper applies blocks under the bundle during wrapping, at the final stage.

Q: How do line speed and ring speed affect the overlap? A: The bundle advance per ring turn sets it. At 16 m/min and 60 r/min, the advance is about 267 mm per turn. At 2 m/min and 30 r/min, it is about 67 mm, which gives a much higher overlap.

Q: How many operators are needed? A: One person, to feed the profile bundles.
