Vertical Strapping Machine 9460TL
Automated Compression Strapping machine
SECTION 1
Strapping Machine
9460TL Strapping Machine Comprising:
This high-performance automatic vertical strapping machine to strap loads (with or without pallets) can be integrated in driven or non-driven packing lines. The strapping unit moves down by dual chains to the top edge of the pack. Strap feed in each strapping position ensures high throughput for min. and max. pack heights.
The unit consists of the following elements.
Machine elements and strapping arch
Heavy duty folded sheet metal uprights with upper frame structurally integrated with base for greater stability built from structural steel.
Vertical movement of the strapping head
The vertical movement of the carriage containing the strapping heads, is achieved through a gear motor / dual chain combination controlled by a variable speed inverter. A sensor detects the height of the pallet (arrival of the lifting frame/strapping head on the pallet during move down) to switch from fast to slow (positioning) speed. The adjustable lifting frame guide rollers with low-wear Vulkolan coating ensure quiet running in the precisely folded running surfaces in the machine columns.
2 x Strapping head GS-41 N
In unique quick exchange configuration provided by heavy duty industrial electrical and mechanical quick-releases.
Ø Three versions of the strapping head are available for different applications with optimal strap feed, take up, and tensioning speed. Maximum strap tension reserves up to 4000 N guarantees a high life time and high reliability of the strapping head.
Ø Low maintenance vibro-welding unit guarantees constant sealing. The strength of PP and PET plastic straps is therefore ensured.
Ø Separate drive sections for fast strap transport and powerful tensioning.
Ø Additional electronic strap circulation control.
Ø Accurate tension alignment of the strap.
Ø Precise and quick adjustment by automatic strap feeding unit.
Floating strapping heads
For an optimal strap tension spreading around the four sides of the product to be strapped, the machine is equipped with floating strapping heads, max. stroke 75 mm.
Automatic strap insert
The beginning of a new coil of strapping material is simply inserted in the easy access strap pipe, located outside of the strapping head. By pushing a push button, the strap insert cycle is then automatically completed.
Twin strap tracks and telescopic strapping arches
In order to shorten the strapping cycle for shorter loads, a telescopic feature reduces the height of the strapping arch when the lifting frame/strapping heads are automatically lowered towards the load. In the process, this feature reduces the amount of strapping material that needs to be fed and taken up. Precision extruded aluminium guides with spring-loaded gates (flaps) provide high feed speed and precise positioning of the strap on the load.
Controls
Control desk built according to VDE 0113 Part 1 and EN 60204-1, using the highest quality components, of generally accepted brands. The control desk is a stand alone type, with a standard cable length of 5m; it is equipped with an Allen Bradley PLC and MMI, with integrated machine efficiency indication. It also comprises of an emergency switch and a potentiometer for strap tension adjustment. Start of strapping cycle via push button or volt-free contact.
2 off Strap dispensers
Coils of PET or PP with a core diameter of ø405 mm can be fitted to these high speed dispensers, with pulley block accumulation system and electrical brake.
Standard surface finish :
Strapping head : RAL 7001 - silver grey (not painted, metal finish)
Machine parts : RAL 7016 - anthracite grey
Moving parts: RAL 7040 - window grey
Control panels : RAL 7035 - light grey

Description of Operation
Automatic Operation
Ø The operator starts the system and sets the required tension.
Ø The product is automatically driven into position.
Ø The head moves down to the top of the pallet.
Ø The telescopic lances are driven through the openings in the base of the pallet and engage in the opposite side of the strap track.
Ø The straps are tensioned around the pack to the pre-determined tension.
Ø The machine then welds and cuts the straps, achieving a weld joint efficiency of approximately 80% of the parent strap.
Ø The strap is automatically pushed around the machine’s arches and back into the heads, where it is gripped.
Ø The heads then lift off the pallet to allow the pallet to be rotated 90 degrees and at the same time lifted to the next strap position.
Ø The head moves down to the top of the pallet.
Ø The telescopic lances are driven under the pallet, through the openings in the turntable and engage in the opposite side of the strap track.
Ø The straps are tensioned around the pack to the pre-determined tension.
Ø The machine then welds and cuts the straps, achieving a weld joint efficiency of approximately 80% of the parent strap.
Ø The strap is automatically pushed around the machine’s arches and back into the heads, where it is gripped.
Ø The heads then lift off the pallet to allow the pallet to be rotated 90 degrees back to the home position and at the same time lowered to the bottom position.
Ø The pallet is driven forward to the last strapping position.
Ø The heads moves down to the top of the pallet.
Ø A single telescopic lance is driven through the openings in the base of the pallet and engages in the opposite side of the strap track.
Ø The strap is tensioned around the pack to the pre-determined tension.
Ø The machine then welds and cuts the strap, achieving a weld joint efficiency of approximately 80% of the parent strap.
Ø The strap is automatically pushed around the machine’s arches and back into the heads, where it is gripped.
The heads lift up and the product is automatically driven out of the machine
