Vertical Strapper L-LV
Code: 580000003Product detailed description
Automatic Vertical Strapping Without Moving the Pallet
VERTICAL STRAPPER L-LV is a fully automatic mobile strapping machine designed for the vertical securing of heavy pallets, bundles and bulky industrial products using PP or PET strapping. Its design is based on the Vertical Strapper L model and is enhanced with a motorised travel system that moves the entire machine along the pallet.
Thanks to this design, the pallet can remain in a single position throughout the entire process. The machine automatically moves between programmed strapping positions and can apply two, three or more vertical straps at the required spacing without repeatedly moving the heavy product.
Motorised Travel of the Entire Machine
The main advantage of the VERTICAL STRAPPER L-LV is its motorised travel system. Once the pallet has stopped in the working position, the machine automatically moves along the product between the individual programmed strapping positions.
This solution is particularly suitable for very heavy pallets, concrete products, paving blocks, building blocks, prefabricated components and other products where repeatedly moving the pallet between individual strapping cycles would be technically or economically inefficient.
Open Frame with Motorised Bayonet
The machine uses an open strapping frame with a motorised bayonet. The bayonet automatically extends through the pallet opening and creates a precise path for guiding the strap.
The entire process is fully automatic without manual operator intervention – from detecting the correct product position and feeding and tensioning the strap to creating a strong joint.
Tensioning Force 100 – 4,500 N
The SIAT GS41 strapping head enables the tensioning force to be adjusted within a range of 100 – 4,500 N. The value can be adapted to the weight, stability and characteristics of the specific product.
Once the strap has been fed around the load, the system tensions it and subsequently creates a friction-welded joint. No metal seals or additional joining materials are therefore required.
Precise Strapping at Programmed Positions
The motorised travel system allows the machine to move between precisely defined working positions. Strap application accuracy reaches up to ± 0.5 mm, ensuring high repeatability of the strapping process.
The number of straps and the spacing between them are configured according to the specific product and required strapping sequence.
2 + 2 Cross-Strapping
VERTICAL STRAPPER L-LV can be combined with a turntable. This configuration enables fully automatic 2 + 2 cross-strapping without the need for a second strapping machine.
PP or PET Strapping
The machine operates with PP or PET strapping in widths of 12, 16 or 19 mm. The appropriate strap type is selected according to the weight, stability and handling requirements of the product.
- PP strapping – an economical and flexible solution for lighter and medium-duty products.
- PET strapping – a strong solution for heavy pallets and products exposed to high dynamic loads.
Automatic Operating Cycle
Once the product stops in the strapping position, sensors confirm its correct position and the machine receives a signal from the higher-level control system. The motorised bayonet extends through the pallet opening and prepares the path for the strap.
The strap is then automatically fed, tensioned to the preset force and joined by the SIAT GS41 strapping head using friction welding. Once strapping is complete, the entire machine moves automatically to the next programmed position and the process is repeated.
SIEMENS S7-1200 Control System
The machine's automatic process is controlled by an industrial SIEMENS S7-1200 control system. This enables the machine to be integrated into the higher-level control system of a production or packaging line and its operation to be coordinated with conveyors and other technological equipment.
Custom Configuration According to the Production Line
The motorised travel length, strapping frame dimensions, bayonet, number of strapping positions and overall workstation configuration are designed individually according to the specific application.
Configuration Options
- Second strapping head for applying two straps in a single operating cycle
- Upper press with a pressing force of up to 2 t
- Automatic protective corner applicator
- Motorised travel system with custom travel length and working positions
- Automatic product centring
- Turntable for 2 + 2 cross-strapping
- Product identification using barcodes or QR codes
- Automatic operating programme change
- Custom colour finish according to RAL
Complete Integration into the Production Line
VERTICAL STRAPPER L-LV can be supplied as part of a complete automated workstation including the motorised travel system, roller or chain conveyors, turntable, upper press, protective corner applicator, safety fencing and communication with a higher-level PLC.
The solution can include analysis of the production and packaging process, workstation design, conveyor system manufacture, safety systems, electrical and software integration, installation, testing and operator training.
