Abstract

In a glass sheet processing/handling machine, at least one electric motor for powering a respective movable member is powered by a drive having a direct power device connected to an industrial electric power mains; and a rechargeable power device alternative to the direct power device and having a storage block for storing energy produced by the electric motor when decelerating the relative movable member.

Claims

1. ) A glass sheet processing/handling machine, the machine comprising at least one movable member movable according to a given law of motion, depending on the process to be performed and/or the type of sheet for handling;

an electric motor for powering said movable member; and

a drive for driving said electric motor and connectable to an industrial electric power mains;

said drive comprising a first direct power device comprising an alternating-direct voltage converter block connectable to said industrial electric power mains, a direct-current power line connected to said converter block, a power-up circuit, and a direct-alternating voltage converter block connected directly to said direct-current power line on one side, and to said electric motor on the other;

the machine being characterized in that said drive also comprises a rechargeable power device for powering said electric motor, and comprising a storage block for storing energy produced by said electric motor when braking, and interface means connected electrically to said direct-current power line and to said storage block.

2. ) A machine as claimed in claim 1, characterized in that said rechargeable power device also comprises precharging means for precharging said storage block and connected to said industrial electric power mains.

3. ) A machine as claimed in claim 1, characterized in that said rechargeable power device also comprises discharging means for discharging said storage block.

4. ) A machine as claimed in claim 2, characterized in that said rechargeable power device also comprises a further alternating-direct voltage converter block connected to said storage block by said precharging means, and to said industrial electric power mains, in parallel with said converter block.

5. ) A machine as claimed in claim 1, characterized in that said rechargeable power device is connected to said direct-current power line by two first connecting terminals;

and in that two second connecting terminals, separate from, and connected to the direct-current power line in parallel with, said first connecting terminals, are provided to connect alternative auxiliary circuits to said rechargeable power device.

6. ) A machine as claimed in claim 1, characterized in that said storage block is a direct-voltage-powered capacitor block.
