The new series of monoblock semi-automatic and automatic shrinkwrappers with sealing bar BP are extremely versatile: they can pack various products, such as glass and PET bottles, cans, boxes, trays, jars, cartons of different sizes in a wide range of pack collations.
They can be used in several industry segments, such as beverages, food, chemicals, wine and spirits, cosmetics, detergents, wood, textile, graphic etc.
The BP series allows SMIPACK to meet a wide variety of customers’ demands and to ensure a very good quality/price ratio.
Motorized upper and lower film unwinding
Pneumatic product pusher, activated by two buttons
Included: feet for the machine fastening, press rod to stop products, cooling fan at the tunnel outlet
Pneumatic sealing bar
Pneumatic film cut by cold blade
Sealing bar equipped with safety sensors
Rollers are positioned on the upper and lower unwinders to make the reels easier to load
Metric graduation based film reels centering system
FLXMOD® electronic control system working by means of a 4.3″ graphic LCD rotating control panel, equipped with PLC
Power and control section made up of:
IN/OUT (Input/Output) command modules with 16 digital inputs/outputs
Analog inputs command modules
Thermocouple reading control modules
Such system allows a simple and accurate control of all current operations, that is:
storing of 20 different working cycles
speed adjustment of the shrinkwrapper and tunnel conveyors by means of an inverter
Tunnel air flow adjustable by means of independent deflectors
Tunnel conveyor equipped with heat-resistant glass fibre bars (SMI patent) which ensures that:
the conveyor stiffness grants stability to the products passing through, for a compact and well-shrunk pack
the conveyor can bear a product weight up to 30 kilos
the conveyor bars never get rusted, as it happens when using traditional metallic conveyors
the maintenance is easy and low-cost, thanks to the possibility of replacing just the worn out bars
Modularity and excellent price/quality ratios are the main features characterizing the manual, semiautomatic and fully automatic sealers of the FP series. All the models of this range can indeed be supplied with or without shrink tunnel.
The INOX version machines are ideal to satisfy the exigencies of the food industry (meat, frozen food, fish, cheese, chocolate, etc.), and are characterized by a stainless steel frame (AISI 304) and the conveyor complying with the FDA, UE and USDA standards, concerning products in direct contact with food.
Compared to the traditional L-sealing hood packers, the FP series provides higher outputs as well as the possibility of using Polyethylene film, besides the traditional shrink films, and includes different models for outputs ranging up to 3000 packs/hour.
Manual sealing system
Double hood hold-down electromagnet, that highly reduces the pressure of the operator on the sealing arm so as to ensure a better sealing
Pack deviation device
PTFE-coated sealing blade
Closed-circuit liquid cooling of the sealing bars
Viewer of the coolant level
Working height of the sealer and of the tunnel adjustable by means of an external crank
Mobile product-holding plate, loose from the film reel support to allow a better adjustment of the film to the pack size
Automatic pack discharge by means of a motorized conveyor
Flextron® control system equipped with:
Alphanumeric LCD control panel provided with a 16-bit microprocessor card and solid state relays
Modular power section, separated from the control panel and characterized by:
longer-lasting solid state relays providing easier maintenance
in case of failure, possibility of replacing just the damaged module, without losing the data stored in the memory
This system allows a simple and precise control of all the machine operations, such as:
number of packs produced by an electronic pack counter
adjustment of the sealing temperature
pack discharge speed
delay in the opening of the sealing arm
possibility of scheduling up to 10 different work cycles, thus resulting in increased productivity and simplified use
Gramegna offers a wide range of sleeve wrappers combined with heat-shrinking ovens. Whether you need a semi-automatic machine with a pedal-operated pusher or a fully automatic machine to be integrated on the line, Gramegna offers multiple solutions for any kind of application. Furthermore, with the HS90° series, the products can enter the machine perpendicularly, thereby forming product compositions in preset sequences. For applications that require very high speeds, extra features such as the lane diverter, the systems designed to insert a flap or a tray before the heat-shrinking stage, Gramegna offers its lines from the R700 and WRAPJET range. These solutions can be customised for each application and any kind of product.
