The dispenser is controlled by a servomotor which is synchronised with the conveyor-belt speed.
Method:
We often mount our dispensers in continuation of the customer’s existing production line but they can easily be set up as stand-alone units and be manually operated.
The solution is made up of a conveyor belt and an Elmoprint SDA dispenser. Both components are IP66 rated and sturdily built for non-stop operation. The width and length of belt and dispenser can be adapted to the given task.
The item is scanned while on the conveyor belt, which defines it in relation to the dispenser. This provides an absolutely accurate placement when the dispenser dispenses the label onto the item.
The label dispenser is controlled by a servomotor that is synchronised with the speed of the frequency-controlled conveyor belt.
Control:
The whole process is controlled by a lightning-speed motion controller, whose settings are entered on an HMI touchscreen. The settings for the respective products are saved as recipes, which enables you to manage several types of items on the same line.
The dispenser can be controlled by selecting from external recipes and it can be included in the general line controls for sharing start and stop signals, for instance.
Dispenser advantages:
- Stable and reliable, even in harsh manufacturing environments (IP66 rating)
- Touchscreen for which all user settings are set and saved as recipes
- Two servomotors can be mounted for electronically adjustable web tension for plastic labels. This maintains constant tension on the label roll while taking account of the fact that the backing paper can give way during rapid acceleration
- Simple to operate during format changeover and it manages 99 recipes
- Maximises uptime
- Guarantees high capacity and unparalleled precision
- The equipment handles semi-automatic and fully automatic labelling feed-in so regardless of whether your products are manually placed (such as on a rotary table) or fed onto the belt from a filling machine, the equipment receives the starting signals it needs
Options:
In addition, we advise you to consider whether to supplement your new system with:
- Tip-over protection, which stops the line if a product tips over
- A rejecting unit that rejects items deemed faulty, e.g. if a lid is not correctly attached or if a product is below the minimum weight
- Identifies products than may be incorrectly label, such as if a product is marketed for multiple brands and you want to make sure that the right label is attached to the product
Master/backup:
If you need to be able to replace a label roll while the line keeps running, you can choose a master/backup solution fitted with two identical dispensers. While the roller is being replaced on one dispenser, the other takes over the labelling process.
There are other benefits of having a backup dispenser, because it can ensure that labels are applied to all products, if it detects a label is missing on the label web, for instance. By having fluorescent material in the labels and a luminescence sensor mounted on the machine, the secondary dispenser will apply labels to any items that might have been skipped by the master dispenser.
Combinations:
The machine can combine different solutions so it comprises multiple dispensers to label products from different sides.
- Top
- Bottom
- Side
- Wrap-around
Printing solution:
Another popular solution is to mount a printing solution on the dispenser for printing a date, batch no., list of ingredients, logo or other data on the labels.
