04 (NW) – Monoblock powder filling

Structure and safety

• Main structure in anodised aluminium profile, completely covered with stainless steel panels.
• Single-motorised infeed and outfeed conveyors: adjustable stainless steel and polyethylene guides. High-density polyethylene bottle transport carousel.
• Bottle sizes up to Ø85 mm, H. 240 mm.
• Safety enclosure in anodised aluminium profile and tempered glass or polycarbonate with mechanical limit switches.
• On-board electrical and control panel in stainless steel.

Dosing system

• Dosing unit with auger, bucket or mixed system, mounted on a column with motorised height adjustment and possibility of rotation outside the bench for disassembly and cleaning.
• Stainless steel hopper with feed opening; powder level control with provision for automatic feeder.
• Electronic dosing control with 256 imp/rev encoder and Siemens high-frequency counter.

Closing unit

• Cap feeder with stainless steel vibrating cup, Ø600 mm, with soundproofing and adjustable pedestal.
• Mechanical or electropneumatic cap positioning unit
• Closing unit for aluminium or plastic caps with adjustable rotation speed and magnetic clutch for closing torque calibration.
• Movement of the locking unit with 2 digitally programmable different speeds

Logic Controls

• Logic control based on Siemens S7 CPU 1200 PLC with special modules for axis control, fast counting and net weight control system.
• Operator interface via Siemens SIMATIC Touch Screen, with alarm list, setup functions and parameter editing.

Checkpoints and alarms

• Minimum and maximum bottle load on the belt (stand by)
• Presence of bottles in dosing (dosing disabled)
• Dust level control in feed hopper (product call – stop after xx seconds)

(OPT.) Net weight System

• No. 2 load cells with a capacity of 500 g and an accuracy of 4000 steps for the entire range, equivalent to 0.1 g.
• Weight control system based on SIEMENS SIVAREX U PLC module with digital filter for vibration compensation: each bottle is weighed before and after filling; the net weight is calculated automatically.
• An automatic calibration and feedback system modifies the dosage settings in order to achieve and maintain weight stability within the set values (EXAMPLE: difference between detected weight and setup value between 0% and ±1.5% OK , tra ±1.5% e ±2.5% autoregolazione dei parametri, differenza maggiore di ±2.5% scarto del prodotto e autoregolazione).
• Electropneumatic system for out-of-tolerance sample rejection management
• All functions controlled from the touch screen operator panel
• Connection to serial printer for reporting and statistics of each batch
