Encoder DMP Options

Techcon Systems can offer the TS5000DMP-DCX with an encoder fitted to the

DC motor. This configuration is available with a right hand side door opening.

Due to machine integration restrictions, the encoder option is available with the

flexibility of 3 encoder positions:

For spare parts, technical drawings, dimensional drawings, wiring diagrams or

encoder information, relating to the encoder valve option, please contact Techcon

Systems.

2. UNPACKING AND INSPECTION

Carefully unpack the valve and examine the items contained in the carton.

These will include:

 Valve assembly

 Valve bracket and syringe bracket

 Sample syringe kit and tip kit

 Sample DMP feed screw/chamber (1 each of 6, 8 and 16-pitch)

 User guide

Inspect the unit for any damaged which may have occurred in transit. If such

damage has occurred, notify the carrier at once. Claim for damage must be made

by the consignee to the carrier, and should be reported to the manufacturer.

3. DESCRIPTION

The TS5000DMP-DCX Series Rotary Microvalve takes a revolutionary unique

approach to solving some of the most difficult dispensing problems. Two-

component fluids present a significant dispensing challenge, and the possibility of

destroying precision valve components, upon premature curing. Highly abrasive

fluids eventually decrease accuracy that is followed by total valve failure. With

the patented Disposable Material Path (DMP) Rotary Microvalve from Techcon

Systems, those concerns are erased.

A precision molded feed screw and chamber is captured in a “clamshell” design

valve housing. Inexpensive disposable feed screw and chamber components may

be changed quickly and easily. Cleanup is reduced to simply changing out the

disposable material path. An inexpensive stock of disposable valve components

replaces an inventory of back up valves.

The accuracy of the TS5000DMP-DCX valve meets the needs of users previously

constrained to lower accuracy of time/pressure dispensing. It also meets the

maintenance cost targets of users previously relegated to recurring, maintenance of

non-disposable path valves. Current TS5000 Rotary Microvalve customers may

find the accuracy of the TS5000DMP-DCX valve meet their current accuracy

specifications.

4. THEORY OF OPERATION (refer to figure 1.0)

The TS5000DMP-DCX Series Rotary Microvalve dispenses fluid with a positive

displacement action using a rotary feed screw principle. Fluid is held in a feed

reservoir (2), normally a syringe barrel or cartridge, under a positive head of air,

between 1 to 20 psi (0.07 to 1.38bar), depending upon the viscosity of the fluid.

The positive air pressure, supplied by the air line (1), forces the fluid out of the

syringe barrel (2) into the material feed path (3) then to the feed screw chamber

(5). Fluid flows from this point (5) to the dispense point (4) and is controlled by

the feed screw rotation in the feed direction. The feed screw is driven by the DC

motor (6). Applying a DC voltage signal to the DC motor (6), will rotate the feed

screw and the fluid will be forced out the dispense tip (4). The actual fluid

deposited is dependent upon adhesion of the dispensed fluid to the substrate.

Shearing of the fluid is achieved by reverse Z-motion (tip retraction). When the

motor stops, the unit remains in position for a fraction of a second (dwell) to allow

the last drop of fluid to flow out of the dispense tip. After the dwell period, the

automation equipment moves the TS5000DMP-DCX valve to the next position.
