AUTOMATIC FORMER MODEL E-7 FOR THE FOLDING AND GLUING OF CORRUGATED BOARD TRAYS WITH REINFORCED CORNER POSTS-WITH OR WITHOUT TOP FLAPS

Picture of a E-7 with ES stacker (option & reference)

CYCLE DESCRIPTION
A single blank is picked by means of suction caps from a magazine where the cardboard sheets lie horizontally.
After the blank is place onto the main transport chain, datum lugs fitted on the chain transport the blank to the forming stations. At this point glue is applied and the corner flap is mechanically pre-folded at a 90 degree angle.
By means of a special dedicated system developed by SMI PAK, the blank stops in the final folding and pressing station where the forming of the corner posts is completed accordingly to standard shapes and sizes that can be erected on the machine.
From here, the partially formed blank is transferred to the forming area after further glue lines have been applied.
Next, the blank is placed precisely into position under the press/mandrel, which completes the construction of the tray inside the forming station.
The individual trays then fall through the forming station onto a conveyor belt below which transports them to the SMI PAK ES stacker(optional).
MAIN FEATURES OF THE MACHINE
Robust frame in welded and painted steel.
High capacity horizontal blank magazine.
Easy adjustments of blanks supports in the magazine by means of platform escales.
The blank is picked from the magazine by suction cups, driven by Venturi meter generated vacuum( one Venturi system for each vacuum cup).
The adjustment of suction cups positioning accordingly to blank dimensions is highly accessible and can be accomplished from the outside of the machine.
Top moving blank guiding system allowing to run bending cardboard sheet.
Extra blank transport system combing motor-driven and skate wheels together, which allows to run thin and light cardboard sheets.
Mechanical corner pre-folding system by means of flap lifting devices.
Transport system of the cardboard sheets by means of a specifically designed motor driven transport chain with datum lugs and frequency inverter, which allow to vary production speed at any time. The main feature of this transport chain is the possibility to stop the blank to allow an accurate forming of the corners despite the continuous constant speed.
The position of the chain can be adjusted so that the position of corner pressing devices will not change.
Corner folding units, one on each side of the machine, composed of one pneumatic folding device for open corners, or two folding devices for closed corners(option).
Corner pressing units, one on each side of the machine. Adjustments can be carried out through hand wheels with platform e indicators. The change over from open to “L” shaped corner type is very easy and intuitive. Changeover parts not required.
Lifting system of the pressing units grants an easy removal of cardboard sheets in case of need, or in the event of a maintenance service or cleaning of the machine. In compliance with the related safety rules, the system is equipped with a mechanical lock which protects the machine operator from harm.
Press unit for the forming of the trays, operated by the vertical movement of the mandrel. The mandrel size depends on the size of the tray to be erected.
Tray forming station equipped with hoppers and pneumatic devices for the folding of top and side flaps. This station also features tray stopping units, as well as devices granting a correct ejection of the tray.
The machine also features:
Fast changeover system thanks to hand wheels with platform e indicators. Quick replacing of the mandrel, when necessary for the change over.
Two fold adjustment of side blank guides: this system is both present under the magazine and in the forming area, thus allowing independent adjustments of the guides at the front and at the back of the machine. This helps compensate any possible width variation of the blanks after the forming of corners.
Adjustments are carried out by means of screws and platform e counters.
Hot-melt gluing system. The basic configuration is composed of a tank/pump unit, 4 pipes and 4 spraying heads.
Reinforced supports for the spraying heads, so as to assure the precision of the glue lines.
Transparent mechacrylate safety interlock guards with aluminum frame. In particular, the micro switches on the side guards are mechanically locked until the corner pressing unit is completely lifted.
Switchboard
HMI with user friendly interface with touch screen panel for an easy access to all machine data(i.e. processed format, machine status and fault listing). Storage capacity: 100 programs.
The machine is supplied with the touch screen panel positioned as standard, yet it can be placed on the opposite side on request.
Painting: frame RAL 2004; panels RAL 7035;
Machine designed and manufactured according to the related CE safety rules 2006/42/CE(2004/108/CE et 2006/95/CE)
