Benefits of technology
"The invention relates to a banding machine that can automatically change bands without interrupting production. The machine detects the end of the band from the first reel and retracts the rest of the band. The machine then inserts the new band into the machine and measures the length of the band to ensure the first loop is formed correctly. The machine has two reels that can be controlled in a programmed manner, and the bands are advanced and retracted using driving rollers and sensors. The machine can also have a sensor to detect the band end and a reference sensor for band insertion. The technical effects of the invention include improved efficiency and accuracy in banding, reduced downtime for maintenance, and improved safety."
Problems solved by technology
Despite the progress in automation and improvements to the individual components, continuous production is always interrupted when the reel from which the band has been unwound has to be changed.
A supervisor has to be temporarily present at a certain banding machine at a certain point in time, which, in addition to the actual interruption to operation, gives rise to additional costs.

Embodiment Construction
[0020]FIG. 1 shows a banding machine 10 with a height-adjustable undercarriage 12 on arrestable wheels 14. A cross-strap 16 of the undercarriage 12 has arranged on it a rear band reel 18 (which cannot be seen) and a coaxial, front band reel 20. Each of the axially displaceable reels 18, 20 has a likewise displaceable band store 24, 25, via which a band 22 is unwound. The band stores 24, 25 each comprise, in the present case, three stationary deflecting rollers 26 and three deflecting rollers 30 which are mounted on a tensioned, pivotable lever 28. In the case of loops being formed very quickly, the band stores 24, 25 serve as a reserve; and the lever 28 is raised. According to a variant which is not illustrated, the band store may also be designed as a magazine.
[0021]The band reel 20 with the band store 24 is in the operating position; the band reel 18 (not visible) with a corresponding band store 24 (not visible either) is in the reserve position. Each of these two displaceable ban...

Abstract
A method and to a device for banding a stack of products which are to be stacked. A band is unwound from a store roll of a band machine and a loop is formed for the stack of products which is to be stacked, by a band insertion / withdrawal unit. After the free end of the band is fixed in a return device and the band is pulled to the stack of products which is to be stacked, the free end is stuck or welded and the pulled loop is cut. In a program-controlled, continuous process and prior to changing the band, the end of the band of a first band roll is detected and the remainder of the band is retracted. Then, the band threaded into the band store of a second complete band roll is inserted into the band insertion / withdrawal unit (39) and the band continuous with delay. The end of the totally automatic band exchange is optically and / or acoustically displayed and the roll can change without pressure.
Description
BACKGROUND OF THE INVENTION[0001]The invention relates to a method of, and an apparatus for, banding a stack of articles, in which a band is unwound from a reel, with a band store, of a banding machine, a loop for the stack of articles is formed by means of a band-insertion / band-retraction unit and, once the free band end has been clamped in place in a return movement, is drawn against the stack of articles, the free end is adhesively bonded or welded and the secured loop is severed.[0002]In a banding machine, a band-like sheet or film made of paper, plastic or a composite material is guided as a loop around the stack of articles in a band guide which forms the outer boundary. This band guide is designed as an open or closed infeed arch, depending on the stiffness of the bands and on the dimensions and usage of the banded stack. For soft bands, numerous means are known for holding up the band during and after passage through the arch; it is always necessary, however, to ensure free ...
