The Customer and his Requirements

There is an old German saying which translates like this: "He who wants honey, must suffer the humming of the bees." Indeed - for one kilogram of honey bees must 'visit' 3.5 million blossoms thereby covering a distance equal to two and a half times the circumference of the earth.

The natural product collected in this way has been used as food and sweetener since the Stone Age and in excess of this is utilized for medical purposes in naturopathy. As a long-established family company from Bremen, Walter Lang Honigimport GmbH has been importing honey from all five continents of the earth since 1895. The product range of the company comprises far more than 50 different kinds of honey as well as various specialities made from honey which are further processed in varying charges. Here, the infinitely selectable filling quantities reach from the 50 g up to the 500 g standard jar via different squeezer bottles up to larger packages. In order to meet the varying customer requirements the company has opted for a new production line which is well able to efficiently fill, label and package different jar sizes using the Kawasaki robot technology.

The Production Flow
Once the cleaned wide neck jars, which are stacked on a Euro pallet in layers, have been brought to the site, they are depalletized by a 4-axis articulated robot type ZD-250S.

Kawasaki robots of the Z series dispose of various arm lengths and handle loads of up to 300 kg. Thanks to their long reach and their small blind angle, these robots can cover a wide workspace. Their small footprint, integrated air pipes as well as their uncomplicated and fast retooling make the robots of this series the perfect depalletizers.

depalletized by a 4-axis articulated robot type ZD-250SAfter having removed the slip sheet, the robot - equipped with a suction plate - is positioned and adjusted above the jars. Thanks to the automatic measurement and adaptation to the pre-programmed pick-up position, the jars are precisely sucked and transferred to the deposit position of the jar table. Now, the jars are singled from four to one track before a conveyor belt feeds them towards the filling station.

Before the filling process, the jar is turned upside down by a turnover device and blown out with high pressure in order to remove potential contaminations. Following the filling process, the jar is lidded and then fed through an automatic labelling system.

Packaging stationThe packages may be as versatile as the contents of the jars themselves. Whether discounter, the demanding food retail industry or the organic retail sales - every customer gets the packaging he desires. For this purpose, a pre-defined tray is folded, glued and made available to accommodate the products. The filled and labelled jars are singled on the conveyor belt depending on the desired number of pieces. Then, a placing robot feeds the 6 or 12 units to the tray prepared.

The placing robot is a 6-axis Kawasaki articulated robot type FS 030L which sucks the jars and carries them from the belt into the provided packaging. Kawasaki robots of the F series with a load carrying capacity of up to 60 kg are the perfect choice if fast handling is important in order to reduce production cycle times.

High speeds, a light and slim arm design as well as a long reach of up to 2,100 mm count among the further advantages of the Kawasaki F series. Short retooling times, high flexibility and an enormous production speed of 20 trays (with 6 units each) per minute grant an efficient flow of the entire honey production.
