Plant sleeving machine with NEFF spindle lifting element and connecting shafts

For our customer Crea-Tech we deliverd this height adjustment of a sleeve machine for plants. This will place the plant in a plastic protective cover.

The height of the rotation plate is adjusted depending on the length of the cover and the height of the plant. The height adjustment is equipped with 4 NEFF spindle lifting elements with trapezoidal spindle and are connected to connecting shafts so that it can be controlled by 1 motor.

An optional Trio Scara Robot can place the plants from the rotation carousel onto a conveyor belt.
