Abstract
In an apparatus for separating valved sacks which are, with the aid of holding bands, coiled in an overlapping formation as a reel and for feeding the separated sacks to a filling machine, a stand for rotatably mounting the reel is provided with a frame carrying a guide roller at each end. An endless driven belt passed over the guide rollers presses against the reel periphery to turn the reel and unwind the overlapping sacks and their holding bands. The holding bands are coiled on spools of the frame while the overlapping sacks are fed to a conveyor which moves faster than the endless belt so as to separate the successive sacks from the overlapping formation.
Claims26
Apparatus for separating valved sacks stored in overlapping formation on reels and supplying same to means for conveying them to filling machines, the improvement comprising:
- a stand provided with bearings for receiving the reel, the stand comprising a frame carrying rollers at opposite ends, that a driven endless belt passes over the rollers and the frame can be applied to the reel or the reel to the frame so that the endless belt presses on the reel periphery for driving same, and that the stand is provided with spools for coiling the holding bands that are pulled off together with the overlapping sacks during unreeling thereof and with a supply belt downstream of the endless reel-driving belt for transporting the overlapping valved sacks, the supply belt being followed by conveyor means which separate the overlapping valved sacks and successively lead same at a faster speed to the means for conveying them to the filling machine.
In an apparatus for unreeling and separating valved sacks stored in overlapping formation on a reel by means of a holding band and supplying same to means for conveying them to a filling machine, the improvement comprising:
- stand means provided with bearings for receiving a reel, the stand means comprising a frame carrying rollers at opposite ends;
- a driven endless belt passing over the rollers and the frame;
- movement means for relatively moving the frame and the reel so that the driven endless belt means presses on the reel periphery for driving same;
- a spool for coiling the holding band that is pulled off from the real together with the overlapping sacks during unreeling thereof;
- and belt means positioned downstream of the driven endless belt for transporting the unreeled overlapping valved sacks to separate the overlapping valved sacks and successively lead same at a faster speed to the means for conveying them to the filling machine.
