Automatic cover opening and closing station ( DOS )

Operating principle

Cover-opening process:

The cover opening device automatically brings the galvanizing drum up to the loading and unloading position, positions itself in the initial position and is then fine-positioned.

When the positioning process described above is complete, the actual cover opening process begins.

It operates as follows:

When the lifting cylinder is extended, the cover-opening tools are positioned at an angle and they grip the cover toggle recesses. The design of the gripping tools ensures smooth gripping of the toggle on the one hand and reliable holding of the cover in the cover opening device on the other.

The cover opening tools are connected by a flat bar, and this ensures that the angle of inclination of the individual tools is identical at all times.

When the cover has been lifted by the opening device, the device returns to the initial position with the cover. The drum can now be loaded and/or unloaded without obstruction. The simple design of this loading and unloading station reduces the number of movements to a minimum. This results in a number of crucial advantages in relation to cost-effectiveness, reliability and service life.

Cover-closing process:

The cover is closed in the same way as it is opened but in reverse order. The device always returns the cover reliably and precisely to the drum opening.

The DOS station can be adjusted in line with the conditions in an existing plant !
