Operation

Figure 2.19

Figure 2.20

Refer to Figures 2.19 and 2.20 for information

on this page.

Initial Procedures

1. Set the Take-up Reel Adjust control to 0

(fully CCW).

2. Turn the TM-300 main power switch ON.

3. Perform the Taping Assembly Setup pro-

cedures described in this manual.

4. Set the Counter Module Preset and Pres-

cale values.

5. Set the sealer controls at the appropriate

levels. Wait for the temperature controls

to stabilize near their set temperature.

To move the cover tape in relation to the car-

rier, loosen the knob on cover tape guide #3

and pull the guide slightly away from the

adjustment dial so the dial will turn freely.

Turning the dial clockwise will move the cover

tape closer to the sprocket holes on the inside

edge of the carrier (ten divisions on the dial

will move the tape .005 inches).

Turning the dial counter-clockwise will move

the cover tape closer to the outside edge of

the carrier (ten divisions on the dial will move

the tape .005 inches).

Push the tape guide back against the dial after

the adjustment has been made and tighten

the knob. Run the tape out again until the

cover tape stops shifting and check the align-

ment. Repeat this procedure until the proper

alignment has been achieved.

Peel Force

In most taping applications a peel force test is

needed to determine the seal characteristics.

Take as many peel force tests as are needed,

while adjusting the sealer controls, to obtain

the desired seal.

Placing Parts

Starting with the left-most pocket, place a part

in each empty pocket for the full length of the

loading track. Close the parts cover (Fig.2.2,

Ref. Q) if desired. Press on the foot switch to

advance the carrier tape through the taping

assembly. Stop the tape advance prior to an

empty pocket reaching carrier tape guide #2

and refill the carrier tape in the loading track.

Repeat until the trailer has advanced to a posi-

tion where the end of the sealed tape reaches

the take-up reel and attach it to the inside hub

of the reel. Adjust the take-up reel tension with

just enough tension to wrap the tape on the

take-up reel. DO NOT APPLY EXCESSIVE

TENSION. Use only enough tension to wrap

the tape. Adjust tension as needed as parts

are added. Continue taping parts until the

counter module reaches its Preset value and

stops the tape advance.

To End Taping

Preset

When the End Count value on the counter

module is reached, the TM-300 will stop. The

last part to pass under carrier tape guide #2

will be the last part counted. Any additional

parts in the loading track must be removed.

Reset

Press the RST button on the counter module to

enable taping of the leader.

Leader

Seal the desired number of empty pockets.

When the last sealed empty pocket has

cleared the drive sprocket, cut the tape just to

the left of the sprocket.

Operation (cont.)

To Begin Taping

Leader/Trailer

Before beginning a production reel, you must

decide how long the trailer and the leader

need to be.

Trailer - The strip of empty pockets needed

at the end of the reel.

Leader - The strip of empty pockets needed

at the beginning of the reel to feed into a

pick and place machine.

The trailer of each reel is taped first. After the

cover tape alignment and any peel force tests

are completed, run out enough sealed empty

pockets to make the trailer. After the trailer is

taped, check the counter display to ensure it

reads 0. If not, press the counter module

RESET button.

Tape Alignment

To ensure an accurate count, the first pocket

in the loading track (left-most) must be a full

pocket. That is, the left-most edge of the

pocket must be aligned with the right edge of

carrier tape guide #2 (Fig. 2.2, Ref. R). If a full

pocket is not showing, lift the carrier tape free

of the drive sprocket and move it back until a

full pocket is showing, then engage the carrier

tape on the drive sprocket at that point.

Counter Enable

Verify that the COUNTER ENABLE SWITCH

is UP and that the counter has been reset.

Maintenance

Figure 2.21

Seal Assembly

DO NOT TOUCH THE HEAT SHOE ASSEM-

BLY WHEN IT IS HOT! IT WILL STAY HOT

ENOUGH TO BURN FINGERS SEVERAL

MINUTES AFTER THE SEALER HAS BEEN

TURNED OFF!

Heat Sealer

Heat sealer maintenance consists mainly of

cleaning built-up residues from the heat

shoes. These residues occur due to a mixture

of dust, tape debris, and cover tape adhesive

which accumulate during taping. Remove the

two bottom screws holding the heat shield to

the sealer. Be careful not to lose the O-rings

which are under the head of these screws and

between the heat shield and the anvil.

Remove the two bolts which hold the anvil to

the sealer assembly. Remove the anvil by

sliding it to one side.

*CAUTION* - DO NOT USE ALCOHOL ON A

HOT SEALER.

Clean the residues from the heat shoes by

using a plastic or brass brush soaked in alco-

hol. DO NOT USE A STEEL BRISTLED

BRUSH. If there are some tough spots, such

as melted plastic, which do not want to come

clean, the sealer can be heated by plugging it

into the taping machine, and then scraped

with the handle of a wood brush or some other

wooden implement.

Alignment

If the seal becomes uneven, where one end of

the heat shoe seems to be striking harder than

the other, DO NOT DISASSEMBLE THE HEAT

SHOE ASSEMBLY. To realign the heat shoes

the sealer must be sent back to the factory.

O-Rings

There are five O-rings between the sealer

assembly and the seal assembly up-right which

provide a seal between the two for the air pres-

sure that drives the sealer. When changing

sealer assemblies, check that these O-rings are

in place and not damaged. When replacing,

place a small amount of adhesive, such as

super glue, on the O-ring before inserting into

the recess. Make sure that the airway is not

blocked.

Tape Path

Loading Track

Occasionally, when the machine is stripped and

cover tape guide #3 is removed, brush the dust

and debris from the track with a small, stiff bris-

tled paint brush.

Cover Tape Guide #3

This may become coated with adhesive and dirt

during taping. It is important to keep the tape

groove clean for proper alignment of the cover

tape. Clean the tape groove with alcohol and a

cotton swab whenever it appears dirty.

Encoder Wheel

The slotted wheel and adjacent sensors may

become covered in dust and debris which may

cause erroneous counting. Brush these off with

a stiff bristled brush whenever they appear dirty.

Air Pressure Regulator

Inspect the air regulator for moisture accumula-

tion (see page 22). Check periodically depend-

ing on air quality and press the petcock on the

bottom of regulator to release the fluid if mois-

ture is present.
