The side rotation belt rotates the product as the label is dispensed and pressed onto the item.
Method:
The side-rotation belt solution is ideal if your production process requires high output and where moderate precision is sufficient.
The high output is achievable by quickly guiding items past the dispenser. By rotating the products between two points, the accuracy is moderate (but still very, very good).
To allow time to dispense the labels onto the products, these are initially separated.
Next, the items are caught by the side-rotation belts – while a label is dispensed at the same instant, in sync between product and application belt, thereby wrapping the label around the item.
Depending on the task, we recommend solutions with one side-rotation belt and a fixed counter-pressure plate or with two side-rotation belts.
The advantage of two side-rotation belts is that the speed can be adjusted to enable the labels to be oriented when the items are released by the belts. This might be significant if you want your products subsequently to be uniformly positioned with the label facing the same direction in a carton, for instance.
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:
- Q format set that enables you to change between item types and label dimensions quickly and easily
- A queue monitor, which prevents the system from advancing items if a bottleneck develops on the belt, while sending a stop signal to the filler machine, for instance, at the same time
- 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
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.
