Fanuc Robot Handles Special Brick Variants

Wienerberger UK has engineered an automated system for handling special brick variants in partnership with Fanuc Robotics UK. The system uses a Fanuc Robotics M710-iC six axes robot to pick up green bricks from an input conveyor and positions them onto a ceramic pallet where they remain until fired.

Bricks are handled separately with a 'suits-all' vacuum gripper solution, a vision system and bespoke palletising software. Single or double bricks enter the system on a conveyor and their precise position is identified by a vision system using Fanuc Robotics IR-Vision integrated software. The M710-iC robot is fitted with a single vacuum gripper that orientates itself to information fed by the vision system and picks up the brick.

The control panel has PC and Human Machine Interfaces (HMI) that allow the shape to be drawn, edited and dimensions to be input. From this information the software defines where the gripper locates the brick, where to place the brick and how to orientate each layer to complete a 950 x 950 x 1,000mm pallet. A robot has been used to draw the sander across each layer as it is completed.

The level of sand dispensed is controlled by the speed, height and tilt of the dispenser as the robot passes it over the bricks. The ceramic pallet is positioned on a rotary table that removes the pallet to an unloading area and positions a new pallet so that uninterrupted production can continue.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
