Modicon history
Modicon created the first programmable logic controller (PLC) in the United States in 1968. The device’s success gave rise to a global industry that has expanded considerably over the past 30 years. PLCs put intelligence in machines and automated processes used in industry, infrastructure and buildings.
1968 With a core group of engineers, Richard E. Morley founded Bedford Associates and invented the first programmable logic controller or PLC. He established the Modicon company, deriving its name from Modular Digital Control.

1969 Modicon introduced the "084" PLC, so named because it was the 84th project of Bedford Associates.

1973 The "084" was upgraded and re-introduced as the "184". The workforce increased from 80 to 170 employees and sales reached $5 million. Offices were opened in Cleveland, Los Angeles and Rochester. 

1975 Modicon introduced the "284", the first controller with a microprocessor and distributed control and the "384, the first PLC with digitized process algorithms for continuous control.  

Cartesien Robot Palletizer 

Takes part of a new family of manipulators / robots for palletizing, developed to satisfy the hight and medium requeriments of production lines, since 400 to 1200 bags / hour. With the maximum rubustness, efficiency and economy. According to most actual demands of automatization it is intelligent, modular and adjustable to the particular needs of each production line.

In this kind of machine, a the arms are moved through three Cartesian Axles and rotate on vertical axle. The bags are caugh one by one from the rollers conveyor to the designed point by the control program. This process has no limit for the the shape of the bags, the degree to which they are filled, or by the type or nature of the materials.

The utilisation of a PLC control system permits the complete automation of the operating movements and the automatic regulation of the position of the mechanical parts which move the bags and the pallets.

The bag dimensions, the number of bags by layer and the coordinates at which they are to be placed, as well as the pallet dimensions can be recorded in the memory, and all this data can be allocated with a program number.

On simple recall of this program number through the interactive screen allows the change of the memorised pattern and automatic adjustement of the machine. This system simplifies the programming and reduces the configuration time.

The intuitive commands in the tactile screen make easier the programing and adjustment of the robot, also, gives a detailed information of all the incidences with the diagnostics program.

The RC 600 Robot palletizer comes complete with safety devices compliant with current EC standards.
 

TECHNICAL DATA

• Maximum speed: 450 - 750 b/h, depending on the number of bags per layer
• Workable bag weights: from 10 to 50 kg
• Minimum pallet dimensions: 800 x 1200 mm
• Maximum pallet dimensions: 1100 x 1400 mm
• Maximum palletized load height: 1800 mm, including pallet height
• Operating system: PLC
• Power supply: 380 V- 50 Hz / 440 V-60 Hz

OPTIONS

• Stainless steel finish of the trapdoors.
• Parts in contact with the bag (rollers, plates, etc.) in stainless steel.
• Dispenser for placing cardboard sheets on the pallets.
• Possibility of working with pallets higher than 1800 mm.

For non-standard pallet dimensions, the technical feasibility of the plant must be confirmed.

History of Elo

A special thanks goes to Jason Ford of Elo TouchSystems, the company whose founder invented touch screen technology, for providing the following historical information.

In 1971, the first "touch sensor" was developed by Doctor Sam Hurst (founder of  Elographics) while he was an instructor at the University of Kentucky. This sensor called the "Elograph" was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology.

In 1974, the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In 1977, Elographics developed and patented five-wire resistive technology, the most popular touch screen technology in use today. On February 24, 1994, the company officially changed its name from Elographics to Elo TouchSystems.
