Glass Service has developed a stirring mechanism with two movements on both the X and Y axes that greatly reduces the space required for the installation and simplifies any maintenance operation.
This machine is a vertical structure attached to the forehearth steel frame.
An electric motor drives the chuck support arm up and down the structure.
This Y movement is achieved by moving the supporting arm on two parallel reinforced rails with special bearings and reinforced wheels.
The motor and gearbox are located on top of the structure with a chain directly coupled to the chuck holder arm. In the unlikely event of chain breakage the arm cannot fall down due to the special design of the rails.
The chuck support arm can easily slide towards the side of the forehearth on a horizontal arm.
This movement is again operated on two parallel and reinforced rails with special bearings and reinforced wheels whilst power transmission is achieved through a rack and pinion. Each spindle turns on large graphite ball bearings.
Thanks to this innovation the following features can be achieved:
Minimum installation space
Any maintenance operation, both on paddles or motor, is simpler and performed away from the hottest area of the forehearth
The re-positioning of the spindles over the forehearth is very simple and precise.

Installed power for spindle arm raising mechanism
On the top of the chuck holder arm the rotors power transmission group is located.
Rotors are driven by a motor plus its gearbox, allowing a perfect control of the rotation speed. This group is designed to allow, for each rotor, the possibility to rotate in two directions, so that, according to the installation the system can be configured as following:
Optionally an inverter can be used to control the rotation speed.
Each moving part of the machine is fitted with steel guards for safety purposes as well as to protect the mechanisms from dust.
The drive assembly is also cooled and lubricated by means of compressed air.
The machine can support any type of rotor currently available on the market.
The chuck and rotor coupling system is a quick release model.
MAINTENANCE AND REPLACEMENT OF STIRRERS
The maintenance and replacement of the paddles/screws is easily carried out and requires very little space at the side of the forehearth.
The operation sequence for this is as follows:
Step 1 - Working position
Step 4 - Maintenance position
