Sonderhoff at Fakuma14: to Present SMART - DM 402 Dispensing Cell for Gasketing, Glueing & Potting

At the 2014 Fakuma trade fair, Sonderhoff Engineering presents the new SMART - DM 402 dispensing cell for gasketing, glueing and potting. The dispensing cell has a new, more compact and fully modular design and is equipped with new built-in safety technology. With the help of standardized individual modules, the dispensing cell may now be adapted to different production concepts in a more flexible way.

In order to further improve the complex, fine-tuned interaction between the dosing machine and the linear robot, several modifications were performed to the SMART - DM 402 dispensing cell.

The mixing and dosing area as well as the linear robot are compactly located on a common base frame of the dispensing cell. Thanks to standardized individual modules, the SMART dispensing cell has a simple and modular design. It has large, rectangular openings close to the lift gates at the front and on the sides as well as inspection windows which can be inserted individually. Thanks to the modularity of the SMART dispensing cell, subsequent modifications due to changed production concepts can be realized quickly and with less planning effort. When it comes to frequently changing applications and part quantities, different modules can easily be attached to the cell body. Unobstructed access to the dispensing cell for maintenance and cleaning purposes is ensured by opening the maintenance door at an angle of 180° over the full height. If, for example, the rinsing containers below the mixing and dosing level must be emptied, this can be done in a user-friendly manner by means of a telescopic drawer.

Easy access to the dispensing cell is also given by the removable cell roof. Without the roof, depending on the adjustable setting of the mounting feet, the cell has a height of 2.20 m. This is of particular importance for ocean transports in maritime containers where the door opening has a height of 2.28 m according to ISO standard.

High user friendliness of the SMART - DM 402 dispensing cell

A better ease of use is achieved by improved accessibility to the mixing and dosing area in the cell. The lockable enclosed machine parametrization with the peripheral system devices is directly located at the rear wall of the cell. The controllers are still located in a separate control parametrization. A separate supply level in the cell floor ensures a protected guidance of the electric and pneumatic lines. The hose guide of the individual material components from the dosing pumps to the mixing head has also been improved.

The machine operator has enough space in front of the dispensing cell in order to easily insert the part. Feeding the dispensing cell with parts for applying foam gaskets, glues or potting compounds is done in a user-friendly manner by means of an automatic rotary indexing table with a 180° partitioning for an insertion and a work position which change within 1.5 seconds. Access to the insertion area on the rotary indexing table at the cell is secured by a light grid.

As an alternative to the rotary indexing table, there is a version where the parts are directly inserted on a worktop into the cell. In this case, a lift gate is att
