Schäfer & Flottmann High Speed Carton Erector Type SFS 350
The innovative design of this high output tray erector was originally developed for the beverage industry but is also suitable for all other applications where a large quantity of pre-formed cartons is filled in the following operation.
All the working sequences are adjusted to ensure that the machine runs smoothly at high speed. The pneumatic movements have been radically eliminated and all the different working sequences are servo driven.
A fundamental characteristic of the machine is the format flexible design, which enables the user to produce an impressively wide range of rectangular, square and octagonal carton formats, as required. Of particular importance are the rapid and easy format changes by means of a spindle adjustment which, as an option, can also be fully automated by a servo drive. Any necessary format parts can also be changed rapidly and safely by means of a quick change attachment system.
The operating principle allows for the folding and gluing of a cardboard blank around a mandrel, using the wrap-around procedure.
The blanks are placed vertically in the magazine and can be loaded during production with the machine running. The blanks are separated and taken by sucking heads, which then place the blanks on the folding mandrel.
After the side flaps have been bent downwards, the blanks are transferred into the first folding station where they are folded into a tube form. The gluing takes place during the transfer. The next step is the closure of the bottom section. During the last working sequence the open carton is evacuated from the machine and transported further in an upright position.
A graphic display informs the operator continually on the actual situation of the machine. The output of the machine depends on the dimensions of the carton. The speed is continuously adjustable up to 60 cartons/strokes per minute.
Advantages at a glance:
