Valve Control

Extend Valve’s Life.  Valve Control for Liquid Filler or Nitrogen dosing.

Air Cylinders and cam driven filler valves are difficult to changeover and have little or no adjustability during the actual filling process. Spring return slamming of the valve reduces valve life.

Valves, whether liquid filler or nitrogen dosing, have spring return that closes the valve in case of air/power loss. This spring force is lighter on gas valves like nitrogen dosing where the forces to overcome them are more within range of SMAC actuators. Liquid valves springs can have higher forces, especially if they are used to fill high viscous material like syrups. These high viscous materials require much higher spring forces to close them. The downside to using a spring return is that the associated slamming of the valve close prematurely wears out the valve sealing surfaces and reduces the life expectancy of these expensive valves. SMAC actuators can gently control this closing and extend the valve’s life.

High Speed Precision Multi-Axis for Pick and Place

SMAC has developed a unique solution for what is believed to be the fastest and most precise three axis pick and place system in the world today.

A solution was needed for a multi-national Japanese manufacturer of luxury goods who were required to both significantly increase product output and improve the flexibility of the manufacturing process.

This highly innovative solution was custom designed by SMAC’s design engineering team in Carlsbad, California, USA. The customer was supplied with a completely pre-assembled, individual parts handling solution. It was designed to be quickly retrofitted into the existing production system within the customer’s factory. One of the key features of the SMAC Moving Coil Actuator solution is that by design it has inherent positioning and feedback capability, a closed loop system that ensures no external sensors or switches are required. This dramatically reduces the amount of external wiring required and facilitates both quick installation and 100% diagnostic feedback and data. The solution was rigorously tested in advance of delivery and ready to install as a turnkey unit. The pick and place system integrated two Multipole Moving Coil Actuators (MCA) one of which was a two axis rotary unit. The Y axis unit, part number MLA15-50 had a stroke of 50mm and the Z unit, part number MLRA15-30, has a stroke of 30mm and an in-built rotary axis of 180 degrees. Due to the exceptionally high speeds and high duty cycle air cooling was used to keep the temperature of the actuators constant. The electronic actuators achieve an exceptionally high degree of speed, accuracy and repeatability by the use of specially designed internal components and SMAC’s high performance electronics. C-sleeve linear guides deliver exceptionally high life expectancy, and a high resolution encoder is integrated into an optimized size footprint. The SMAC system is complemented by four high speed Galil electronic controllers which were incorporated into the solution.

The new system enables perfect quality and allows production times to be tripled. It also enabled the customer to increase manufacturing throughput and flexibility by rapidly switching to new parts for different products quickly. Previously, manual machine change over of parts was required. The SMAC solution reduced existing cycle times from 900 milliseconds to 300 milliseconds while being operated 24/7. It is now believed that the SMAC solution sets a new benchmark as the fastest and most accurate pick and place machine automation system in the world. Because it is SMAC proprietary technology, it can be freely used for other customers and other applications. It is ideally suited for the handling of any micro-components where fracturing and damage occurs during the production process when using conventional solutions such as pneumatic devices, ball screw and servo systems. It is particularly suited to SMT and chip placing applications.

Electric Actuators Replace Pneumatics for Testing

SMAC electric actuators (Moving Coil Technology) are replacing conventional pneumatics in standard QC and Switch Test applications due to the high degree of precise force control and programmability.

Major global manufacturers of mobile phones are replacing their in-house pneumatic production and test systems with SMAC electric actuator systems. The major reason for the change is the precise force control which allows the testing of different parts of the phone key pad with different forces, extremely difficult and costly to do with old fashioned pneumatic devices. Also, highly accurate positioning control within 20 microns is possible, and the unique SMAC electric actuator solution also delivers a more compact and neater solution with lower installation, maintenance and running costs.

The SMAC electric actuator systems provide 100% feedback and data provision for the manufacturer’s QC checking, SPC and quality systems. This in-line testing significantly improved quality, reduced waste and increased efficiency during production.

Volumetric Filling Machines

Improve Filling, Reliability and Accuracy
Improving machine throughput

The flexibility offered by the servo based Exlar actuator offers you the ability to manipulate flow rates or volume instantaneously, without setting any switches or changing out any cams. Container size, volume, or liquid changes are simple to obtain – just enter a new setting in the operator interface panel, or have a PLC do the changes. Operate independent lanes or synchronize all the pumps together. The GSX Series provides a wash-down compatible, sealed design in a compact package. Replacing the cams or fluid power cylinders can be an easy retrofit resulting in better performance, less maintenance and longer life of your machine. Exlar actuators are being used to pump many products including milk, fruit juice, gelatin, yogurt, pudding, pet food, soup, and cake batter. Even paint, lip stick, grease and solvents are being pumped.

Replace the cams or air cylinders in your volumetric filling machine with an Exlar actuator and you will see precise volume control and an accurate fill rate! With an Exlar GSX Series actuator operating the piston pump, users are achieving better than 0.1% fill accuracy.

Heart Valve Material Testing

A medical device manufacturer needed to test a heart valve material for long term fatigue. They wanted to duplicate the heart beat profile to simulate actual conditions.

Because SMAC actuators can be programmed to develop the heart beat motion profile, they were a perfect choice for the application. By measuring the force used to stretch the material to the prescribed length, the gradual degradation of the material could be continuously monitored.

Key Operational Details:
Each finger is driven by an independent linear actuator
Each finger is programmable in position and force

SMAC Advantages:

  • Independently operated fingers means that parts need not be precisely centered
  • Complicated motion profiles can be generated to accurately simulate heartbeats.
  • Force can be monitored, so as the material degrades the resulting change in force as the material is exercised can be used to indicate a failure mode without stopping the test.

Bottle Filling Line Rejection System

This application rejects bottles or cans from a filling line.

The level of liquid in the bottle determines if it is accepted or rejected. This is sensed as the bottle passes through an inspection process upstream from the actuator station. If it fails this test a signal is given to the SMAC controller to perform a cycle. There is a delay between the bottle being sensed and the signal being given, which is controlled by a PLC on the line.

There are two routines programmed into the unit. The first (program “A”) is a two-stage move consisting of a slow move out to an interrupt position, followed by a fast out and retract move. The second (program “B”) is a simple out and retract, for high speed applications. There are three “A” profiles set in the controller and one “B” profile, along with an edit routine for each. The three different “A” profiles are selected using input channels, the program has to be stopped and MS240 typed to run profile “B.” There are a number of registers used to store the three positions (start, interrupt, final) and two accelerations (initial, final). Editing is done through an OMRON PLC using the RS232. All setup is by touch screen via RS232 to the controller. The operator sets the profile needed. The LAL90-50 actuator and LAC1 controller sit inside a stainless steel box. This is necessary as the unit will be in an environment that will be washed down regularly. The rod exits the box through a 10mm wiper seal. The cable from the actuator will have the 25-pin D-type connector replaced by a 15-pin connector and will plug directly into the controller.

The SMAC system improves upon the previous method because: – The previous system was pneumatic, and if the cylinder did not reject any bottles for several hours and then had to reject one, static friction in the seals would cause the first cycle to be slow and ejector could be hit by the next bottle in the line. – The profile can be changed for different bottle shapes. Slow approach then high speed means bottles do not fall over, an important factor for high-cost liquid bottling. This could not be done with the previous system. – Out and back movements in 50ms means the actuator is suitable for lines up to 1,200 bottles per minute, good for filling glass bottles. (Cans run about 2,200 per minute and are usually split into two inspection lines of 1,100 per minute each.)

Better Control of the Welding Process

Application
Machine for automated production of blood bags

Colpitt has traditionally used pneumatic or hydro-pneumatic cylinders to control the movements of their blood bag welding machines. However, they were not able to control the process as precisely as this application required. Colpitt was looking to switch to an electric servo system which could control all the motion for this process through PLC programming providing better control of the welding process.

GSX40 and GSX50 servo actuators were used in this application offering Colpitt the ability to manipulate motion parameters instantaneously, via an operator interface panel, eliminating the need for setting switches or changing offsets. This allowed Colpitt to achieve a quick transfer motion combined with a controlled low speed move for pressing at the end of each move. Not only did this help Colpitt maintain a high cycle rate, it also allowed them to achieve the accurate pressing control that their application requires. The integrated nature of the GSX servo actuator allows both force and speed to be set very precisely resulting in an accurate and easily controlled process.
