The invention relates to a loading system (LS) for an optical machine, that has a carrier (TR), which can be moved in a movement plane (x-y) by way of two linear guide units (LF, LF). At least one holder (H, H, H) for a workpiece, block piece and/or tool is mounted on the carrier, which holder can be moved in a transverse direction (z), which is perpendicular to the movement plane. The linear guide units are designed and arranged in the manner of an H gantry or cross gantry, with two stationary drive motors (AM, AM) for driving a tension element (ZG) in the same direction or in opposite directions, which tension element is movably arranged on the linear guide units in an H shape or cross shape and is fastened to the carrier.

Loading system for an optical machine, in particular for loading and unloading optical workpieces, such as eyeglass lenses, and deblocking apparatus comprising a loading system of this type

A hydraulic arrangement (HA) for an apparatus (AV) for deblocking optical workpieces (L), from associated block pieces (B), includes a nozzle arrangement (DA) for delivery of high pressure jets of pressure means for deblocking the workpiece from the associated block piece at a first pressure and for cleaning the blocked workpiece and/or block piece at least one second pressure which is different from the first pressure. Furthermore, there is a pump device (PE) which applies pressure in a defined manner to the pressure means and conveys it under pressure to the nozzle arrangement. The pump device has at least one high pressure pump (HP, HP) which is drivable by an associated rotary drive (SM, SM), the speed of which is modifiable in order to adjust the first pressure or the second pressure.

Hydraulic arrangement for an apparatus for deblocking workpieces, in particular eyeglass lenses, from associated block pieces

The invention relates to a deblocking device and an associated method for deblocking optical workpieces, for example, eyeglass lenses. The deblocking device has a first moving apparatus for rotating a workpiece blocked on a block piece about a workpiece rotational axis, a nozzle assembly having a nozzle for discharging a high-pressure pressure medium jet in a direction substantially perpendicular to the workpiece rotational axis onto an edge area between the workpiece and block piece, and a second moving apparatus for generating a relative motion between the workpiece and the nozzle along the workpiece rotational axis.
