Abstract
A bag manufacturing system has at least one tube forming device which forms a tube and separates the tube into tube pieces, and at least one bottom forming device which provides the tube pieces with a bottom and thus forms the bags. The system has a storage device for storing the tube pieces on at least two levels. At least two charging and removing devices are provided with which the tube pieces can be supplied to and/or removed from at least two different points of the levels of the storage device.
Claims15
A bag manufacturing system comprising:
- at least one tube forming device, which forms a tube and then separates the tube into tube pieces;
- at least one bottom forming device, which provides the tube pieces as to form bags;
- a storage device that stores the tube pieces on at least two tiers in a stack having a first side and a second side;
- and
- at least a first loading and unloading device and a second loading and unloading device that supply the tube pieces to and remove the tub pieces from at least a first point at the first side of the at least two-tiered stack and a second point at the second side of the at least two-tiered stack of the storage device,
- the first loading and unloading device and the second loading and unloading device each including a lifting table that (i) moves vertically to access the tiers of the stack and (ii) has associated therewith a conveyor belt that transports the tube pieces in a transport direction,
- with the first loading and unloading device supplying the tube pieces to the first point at a same time that the second loading and unloading device is removing the tube pieces from the second point.
