Lareka NP60

Lareka NP60

INFO

The challenge:

In the past year, Lareka has developed a versatile, low-volume wrapping machine (BTB25) for chocolate tablets ranging from 25-250 gr. for artisan chocolatiers. As a specialist in packaging solutions for small chocolates tablets, we have been able to design a similar machine for products ranging from 5-25 gr. This so-called “little brother” of the BTB25 wraps 60 small tablets/min. and is the best solution for chocolate enthusiasts working with low volume, artisan, personalized and high quality products.  

 

Our proposed solution:

Lareka NP60 wrapper:

The NP60 is a single phase tablet packaging machine for small tablets. It has a capacity of 60 tablets/min.

Process specifications (How):

The scope of delivery starts with an in feed conveyor (approx. 1.75m) on which the operator manually slides the chocolates row by row from plates. The infeed conveyor is indexed by a motor (short side leading). When the chocolate reaches the folding position, the machine is triggered to start a new packaging cycle. Both inner layer and outer layer are taken simultaneously, positioned over the tablet and glued. After which the tablet together with the packaging materials are pushed up through the folding box and the four bottom folds are made. Then, the tablet is pushed out (layer of one tablet high) through the output gutter. This is where the scope of delivery ends.

 

The speed is 60 tablets/min.
