SCHNELL BAR WISER TA/22 2024067

· NAME:

MULTIFUNCTION PLANT MOD. “BAR WISER 22 T.A./12”

FUNCTION

‘Bar Wiser 22 T.A./12’ is a twin-head dual-direction stirrup and rebar bender apt to process steel fed in bars. The lower bending unit performs downward bends.

It is driven by digital electric servomotors.

CAPACITY

Bar Diameter Range for double feed: 8-16 mm

Bar Diameter Range for single feed: 8-22 mm.

CONFIGURATION

Clamping unit to extract rebars and lower then to the 2nd bending unit;

additional feed unit to perform downward bends automatically;

bar-holding clamp for downward bends;

12-metre ‘bridge’ collecting bench;

computer with “KS 104” graphic display.

SIZE

1,760 x 5,080 x 3,520 (h) mm

WEIGHT

approximately 9,500 Kg

AVG. CONSUMPTION

Electric power: 8 kW/h

(depending on the diameter of the processed rebar)

Necessity of compressed air: machine working pressure: 7 bar.

EQUIPMENT ON ISSUE

Fixed dual-rebar blade for Ø 10 ÷ 12 mm rebars

Fixed dual-rebar blade for 16 mm rebars

Fixed single-rebar blade for Ø 22 mm rebars

Central bending pins: Ø 32; 50; 70 and 100 mm.

UPPER FEED UNIT

It consists of:

2 units driven by a servomotor, each including 4 rollers (2 motorised rollers and 2 pressure rollers).

The primary feed unit, which is located at the bar feeding point, feeds the rebars into the machine.

The additional feed unit - which is located near the cutting point and is equipped with a measuring roller – checks the rebar position as far as the output point.

A pneumatic pressure system ensures that all rebars are pulled by the feed unit without damaging their outer surface.

Feed speed: 95m/min.

LOWER FEED UNIT

It consists of 4 rollers:

2 motorised rollers

1 pressure roller

1 measuring roller

It is located in the lower processing unit and feeds the rebar to the lower bending head which performs downward bends.

This unit is driven by an electric gearmotor.

CUTTING UNIT

It consists of a fixed blade and a mobile blade which is supported by a stirrup and powered by an electric motor. Fixed blades function as rebar guides and may be replaced within just few seconds.

BENDING UNIT

It consists of a rotating and retractable bending arm driven by an electric motor.

The whole bending unit is lowered or lifted by a pneumatic system thus allowing dual-direction bends.

Bending rate: 840°/sec.

CLAMP

Mobile clamp on 3 axes operated automatically by a pneumatic device which allows:

• Shifting the rebars from the upper to the lower processing unit to perform downward bends;

· Automatically removing any off-cuts which should escape check by the feed unit.

VICE

It consists of a pneumatically driven device designed to clamp the rebars while they are bent downwards by the lower bending unit.

COMPUTER

Industrial computer mod. “KS 104” designed to work in very harsh environments.

It is equipped with a graphic display and manages all the functions performed by the machine including the following:

• Programming any stirrup or shape with up to 30 bends from the control keyboard; programmed shapes are immediately displayed in scale;
• Programming up to 5 different shapes or stirrups on any rebar;
• Storing up to 500 different shapes;
• Programming gradually increasing stirrups;
• Automatic gradual reduction of feed and bending speeds according to the size of the programmed stirrups;
• “Spiral function”: this function allows setting any shape for continuous automatic production avoiding any intervention on the part of the operator;
• 3 standard RS 232 / RS 422 / RS 485 outputs allow connection to a barcode reader and an office computer for remote programming and upload of production data through serial connection;
• Programming the three-armed stirrup collecting robot;
• Adjusting the bending angle without interrupting the working cycle;
• Continuous variation of the bending and feed speeds by means of a potentiometer without interrupting the working cycle;
• Graphic display of the rebar cutting schedule in order to reduce the quantity of off-cuts and to optimise cutting;
• Choosing among 7 different languages;

· Trouble-shooting program to detect any failure.

ADVANTAGES OF “BAR WISER 22 T.A./12”

“Bar Wiser 20 T.A./12” is a highly flexible multifunction plant: the ideal solution for small-medium bar shaping plants and an additional equipment for large rebar processing plants.

“Bar Wiser 20 T.A./12” is a cutting bench + bending robot + stirrup bender all in one. It ensures a high efficiency especially for those customers who mainly manufacture products for housing purposes.

Outstanding features::

• One single operator is needed to operate the machine;
• Automatic manufacture of stirrups and shapes in the 18-20 mm diameter range (not available in coils);
• Reduced overall dimensions compared to an ordinary rebar processing plant;
• Reduced production time: the mobile bar feeding station allows shifting between different diameters in just few seconds;
• High production rate ensured by the equipment’s complete automation and by the optional motorised collector which allows stocking complete bundles;

• Automatic sorting of the processed material by means of an optional collector which allows collecting and classifying rebars and shapes of varying diameters and length;

• Reasonable purchase price.

SCHNELL TECHNOLOGY

Thanks to Schnell’s electric servomotor technology that marked the birth of a new generation of machines - on account of which Schnell is now known world-wide as a genuinely modern company - “Bar Wiser T.A.”, too, can boast the features described below:

• reduced power consumption;
• minimum noise production, thus complying with the regulations on noise levels in work places;
• the equipment is environmentally friendly as it contains no hydraulic circuits or tanks;
• it is extremely reliable and consequently repairs and maintenance are very cheap;
• working tools - such as cutting blades and bending pins - are easily replaced;
• the computer’s Windows interface makes it easy even for inexperienced operators to learn how to use the machine’s specific functions..
