Slitting With Batch Coding Machine – RK HSI-320

It is a label finishing machine for die cut self-adhesive label rolls that combines three operations. The bottom 24" table is made for fixing a batch coding unit, which prints batch, date or MRP data on each label as the web passes. The coding unit is not supplied with the machine; the customer fits their own, or RK can fit one at extra charge. The web then goes through a slitting unit with both rotary and normal shear blades and is rewound on an up and down rewinding system, on 1", 1.5" or 3" cores up to 300 mm diameter, with a Panasonic sensor counting labels.

Above the coding table is a 24" inspection table where the operator checks the coded labels, and a missing label detection system that stops the machine and positions the gap on the table whenever a label is missing in a single or double up layout. The unwinding unit takes rolls up to 600 mm diameter on a 3" manual shaft, with mechanical brake tension and an imported ultrasonic web guide. Two 1 HP AC motors on individual Schneider variable frequency drives, a Schneider PLC and a full touch HMI screen control the machine.

Batch Coding on the Same Pass as Slitting

The 24" bottom table is built for fixing a batch coding unit. Batch number, MFG/EXP date and MRP are printed on the label roll while it is being slit and rewound, so the coding step does not need a separate machine or a second handling of the roll. The coding unit is not supplied with the machine; the customer fits their own, or RK can fit one at extra charge.

Inspection Table to Verify Every Code

The 24" top inspection table gives the operator a clear view of the coded labels as they pass, so a faint, smudged or misplaced code is spotted on the machine rather than at the customer.

Missing Label Detection

A sensor reads the die cut gap. If a label is missing, in single or double ups, the machine stops and positions the gap on the inspection table for correction. Rolls go to the applicator complete.

Rotary and Shear Blade Slitting

Both slitting attachments are fitted, covering paper and film label stocks, and an air blower system collects the trim.

Up and Down Rewinding on 1", 1.5" and 3" Cores

Two rewinding positions wind the slit rolls up to 300 mm diameter. The core size is selected on the touch screen, and the rewinding direction can be switched between forward and reverse to suit the customer's labelling machine.

Label Counter With Auto Stop

A Panasonic label counting sensor and a meter counter stop the machine at the set count, so every coded roll leaves with the exact number of labels.

Schneider PLC and Touch Screen Control

The machine is controlled by a Schneider PLC, with a full touch HMI screen. Both 1 HP motors have their own Schneider variable frequency drive.

Single Phase Power

Power consumption is 2 HP single phase, so the machine can be installed in a small packaging or label unit without a three phase supply.

The pre-printed label roll is mounted on the 3" manual shaft of the unwinding unit. A mechanical brake holds the unwind tension and the ultrasonic web guide keeps the web running straight, which matters for coding because the print position on every label depends on it. The web passes over the batch coding unit fixed on the bottom table, which prints the batch, date or MRP on each label, and then across the top inspection table where the operator checks the codes. If the missing label sensor finds a gap, the machine stops with the gap on the table.

After inspection the web goes through the nip roll and slitting unit. Rotary or shear blades cut it into the finished widths and the air blower removes the trim. The slit rolls wind on the up and down rewinding shafts, on the core selected on the touch screen, with a mechanical clutch holding the rewind tension. The Panasonic sensor counts labels and the PLC stops the machine at the set quantity, so the operator removes a coded, slit, counted roll and starts the next.

• Pharma labels – batch number, MFG/EXP and MRP coding on every label roll, with missing label check, before dispatch.
• Food and beverage labels – date and MRP coding on pre-printed rolls for bottles, jars and pouches.
• Cosmetics and personal care – batch coding on small label rolls slit to the applicator width.
• Label converters – offering coded, slit and counted rolls as a finished product to packaging customers.
• Contract packers – re-slitting and coding supplier labels to fit their own labelling machines.

The HSI-320 runs die cut self-adhesive label rolls with a gap between labels, up to 320 mm wide, on paper, thermal and synthetic film label stocks. The coding result depends on the label surface and the coding unit chosen, so tell RK the label material, the data to be printed and the layout (single or double up) when you enquire.

RK Label Printing Machinery Pvt. Ltd. has manufactured label printing and converting machinery in Ahmedabad, Gujarat since 1995, operates three manufacturing units and supplies customers in 23+ countries. RK builds batch coding machines, slitters and inspection machines in the same range, so on the HSI-320 the coding table, missing label detection and slitting are engineered together. Installation and operator training are done at your site by RK engineers.

• Coding only or coding plus slitting: if the rolls are already at final width, RK's roll to roll batch coding machine may be enough; if they need slitting too, the HSI-320 does both in one pass.
• Data to print: batch, MFG/EXP, MRP – confirm the coding unit type for your label material.
• Label layout: single or double up, die cut with a gap, for the missing label detection.
• Cores and rolls: rewind up to 300 mm diameter on 1", 1.5" or 3" cores; unwind up to 600 mm.
• Output: 100 m/min mechanical speed; actual output depends on label size and coding.
• Power: 2 HP single phase.

The price of the HSI-320 depends on whether RK fits a batch coding unit on the bottom table (extra charge), slitting blade sets, rewinding shafts and options. RK quotes ex-works Ahmedabad with GST at 18% applicable; engineer travel and stay for installation and training at your site are borne by the customer. Send RK your label sizes, materials, coding data and monthly volume for a configured quotation.
