Healthcare high-speed wrap-around labeling-by-herma

22 June 2020

With wrap-around labeling of up to 400 products per minute, the HERMA 132M HC labeling machine advances into new dimen-sions. Streamlined for a particularly high cycle rate, the machine is primarily designed for round pharmaceutical products, such as glass vials and the corresponding high batch sizes in the healthcare industry. These also include measures for the optimiza-tion of overall equipment effectiveness, such as innovative rotary tables, electronic position indicators and format sets that can be exchanged without tools for fast format changes, as well as opera-tion of the entire machine, including the camera and printer, via an industrial panel PC (IPC) and thereby for the first time via a single monitor. The operator therefore no longer needs to set up and op-erate the machine and its components via multiple panels. Fur-thermore, the machine already has complete pharmaceutical equipment on board, including a selection of various printing and control systems, an automatic label return with cross check, which

makes the rejection of poor tested labels particularly simple and secure, as well as one of several possible product reject stations. As an alternative to the thermal transfer printer, a hot-foil printer or laser printer can also be integrated.

Rotary table for any format

The wrap-around labeler 132M ensures power with utmost reliabil-ity right from the start. The newly developed rotary table by HER-MA has a magazine holder for complete trays. Quick-change for-mat parts allow the use of various tray sizes and products. With a product blade, the products are pushed out of the tray onto the ta-ble, without an operator needing to reach into the rotating product transport. “This way, we reduce the risk of products falling over on the rotary table and disrupting the process”, says Ulrich Fischer, Head of Product Management at HERMA Labeling Machines. “For the same reason, the rotary table is very smooth-running with low-vibration.” To guarantee the reliable clearance of the table and to ensure the “Line Clearance” requirement, the respective last prod-ucts are conveyed onto the conveyor belt using compressed air. An automatic filling level check helps to prevent that the rotary ta-ble runs empty during production. A protective cover is also op-tionally available for the table, which significantly reduces the noise level especially with glass bottles. The rotary table is availa-ble as an infeed rotary table and as an outfeed rotary table for the machine.

Not just for pharmaceutical products

The high labeling speed and at the same time extreme precision is made possible by the new HERMA 500 applicator in particular. The patented label return with subsequent cross check ensures additional performance enhancement and maximum process reli-ability. With its assistance, incorrect labels remain on the backing paper and are not, as previously, dispensed on a collective label role that reduces output performance. With the new label return,

labels with deficient quality remain on the backing paper. After the completion of the batch, the user can easily unwind the backing paper and analyze and document each incorrect label. The op-tional cross check includes inspection of the successful rejection of the labels out of the process. This way, possible sources of er-ror can be identified more quickly and eliminated efficiently for the further process cycle.

The option of high-speed labeling is not only of benefit for use in healthcare applications. The 132M HC is specifically geared to the requirements of pharmaceutical products; however, it can be easi-ly configured for numerous industry applications - even without printers and control systems.
