Additional Fixtures, Loading and Unloading Systems

An important function after the machining process is the in-loading and/or loading of the machine carriers and/or work pieces. The retraction (raising) of the upper working wheel by a small distance plays an important role in ensuring the efficient and safe loading and unloading of the machine.

It is necessary to lower the outer pin ring to allow the loading and unloading procedure with the loading/unloading table and the carriers. This forces the user to engage the carriers carefully into the mesh of the gears when inserting them.

Thanks to the position control of the center drive and the appropriate partial lowering of the outer pin or toothed ring, it is possible to load and unload both manually and automatically. This function can also be combined so that you load on one side and unload on the other.

To allow the machines to achieve their full efficiency, it is necessary to pay more and more attention to all of the related circumstances. The machine manufacturers are being encouraged to produce integral solutions, for instance to automate the working process, cleaning, checking, packaging , etc.

Fixtures of all kinda, such as the loading and unloading table (figure 10, 11, 36), are well-known. They allow you to load the the work pieces into the carriers while the machine is running.

In the same way, “tricky” work pieces can be placed carefully into cleaning cages, etc. after unloading.

The loading/unloading of the cages into the machine is carried out semi-automatically (Figure 36). As the cages always have the same outer dimensions, there is no need to change any settings when changing the product. This makes this type of automation extremely successful even in small series with a wide product range.
