UGE048/1103 CSC Combination Puller/Cutter

DANGER: Sharp blades!

Most injuries caused by knife blades occur
when the cutter has been turned off. Handle
blades with care at all times.

● Always wear cut-resistant gloves when the
cutting chamber is open and when handling
blades.

● Always lock out the cutter before opening the
cutting chamber.

● Always wait until the cutter head has stopped
completely before opening the knife guard.

The puller/cutter combo is equipped with sever­al safety devices to ensure safe operation.
Never remove or disable these devices to sus­tain production. Operating without these
devices can cause severe injury.

● When the knife guard is opened, the knife
guard switch stops the cutter and prevents
starting the cutter again.

● Two proximity-type safety switches prevent
operation unless the cutter bushings are in
place.

● The Cutter Stop button activates a circuit that
stops the knife.

WARNING: Improper installation,
operation, or servicing may result in
equipment damage or personal
injury.

This equipment should only be installed,
adjusted, and serviced by qualified technical
personnel who are familiar with the construc­tion, operation, and potential hazards of this
type of machine.

All wiring, disconnects, and fuses should be
installed by qualified electrical technicians in
accordance with electrical codes in your
region. Always maintain a safe ground. Do not
operate the equipment at power levels other
than what is specified on the machine serial
tag and data plate.

CSC Combination Puller/Cutter UGE048/1103

1-4 INTRODUCTION

WARNING: Voltage Hazard

This equipment is powered by one- or three­phase alternating current, as specified on the
machine serial tag and data plate.

A properly-sized conductive ground wire from
the incoming power supply must be connected
to the chassis ground terminal inside the electri­cal enclosure. Improper grounding can result in
severe personal injury and erratic machine
operation.

DANGER: Pinch Hazard!

Never remove or disable safety devices to sus­tain production. Operating without these
devices could lead to hazardous conditions that
can cause severe injury.

● Walk-through style belt guards which protect
from injury, but also allow side entry for ease
of operation. Upper and lower belt guards
independently protect the operator from
being caught in the belts or associated dri­ven sheaves.

● The power cord is attached to the upper
guard by a receptacle on the rear side of the
guard. You must disconnect this power cord
to remove the upper belt guard, ensuring
that the puller will not start if the upper guard
is not in place.

● The flip up safety switch on the discharge
end of the upper belt guard allows operation
only when in the down position. If a finger or
piece of clothing is caught on the upper belt
and drawn in, the guard flips up and immedi­ately shuts off the power to the entire combi­nation puller/cutter.

● The emergency stop (E-stop) button is locat­ed on the control panel on top of the upper
belt guard at the upstream end. Pressing
either of these disconnects power to the
entire unit. The E-stop must be physically
pulled up to reset the switch and start the
combination puller/cutter again.

● When the knife guard is opened, the knife
guard switch stops the cutter.

● Two proximity safety switches prevent cutter
operation unless the cutter bushings are in
place.

● The Stop button on the cutter control acti­vates a circuit that stops the knife.

ATTENTION:

DESCRIPTION

The Conair CSC Combination Puller/Cutter pulls small- to
medium-sized extruded products through sizing and/or cooling
tanks and cuts the product to lengths. Since the puller and cut­ter are mounted on the same chassis, alignment problems are
minimized.

The puller portion's direct AC drive system offers extremely
good speed control, which can be further improved by using
an optional servo motor. Different puller belt materials opti­mize performance with different types of extruded materials.

The cutter portion utilizes a position-controlled servo motor.
CSC units achieve park position repeatability less than 0.1
millisecond.

Combination Puller/Cutter are available in several sizes:

Conair Combination Puller/Cutters can process extrudable
plastics and rubber both on- and off-line. Other extrudable
materials-foods, ceramics, magnets, soaps, etc.-may also be
processed depending on specific application requirements.

Combination puller/cutters are available with different puller
sizes (3, 4 inch widths with traction lengths of 20, 26) and dif­ferent cutting capacities (2, 3, 4, and 5 inches) to suit your
specific needs. The cutter servo motor size and cutter head
material may also be optimized for specific applications.
While the standard orientation is right-to-left, combination
puller cutters can also be made with a left-to-right orientation
(see Specifications, Section 2). (The illustrations in this User
Guide represent the standard right-to left configuration.)

CSC cutters are limited to a specific range of product sizes
based on each unit's cutting capacity. CSC cutters can operate
over a range of speeds (depending on which options are
included.) See Specifications, Section 2.

Different materials, line speeds, temperatures and material
cross-sections can result in different cutting torques. If you are
changing any of these parameters, consult your Conair service
personnel to be sure your equipment can handle the changes.

ESCRIPTION 2-3

TYPICAL
APPLICATIONS

LIMITATIONS

●Because the maximum distance between the puller

and cutter is only six inches, the combination puller/
cutter is not suitable for larger rigid extruded parts.

●The unit is limited by the traction length (the length

over which the extrudate is in contact with the puller
belts), which is fixed for a particular model.

●The outer surface of the puller belt material will

affect performance. Softer (low durometer) materials
provide good 'grab', but will wear more quickly, and
may tear if the belt jams. Harder materials last
longer, but may not grab the extrudate properly.

Contact Conair for specific belt material recommendations for
your product.

CSC Combination Puller/Cutter UGE048/1103

2-4 DESCRIPTION

Extruded material that has been sized and cooled enters the
combination puller cutter from the upstream side. The extru­date passes through and is positioned by guide rollers (Step 1).

Two opposing belts move the extrudate through the puller
(step 2). These belts have grooves that fit the teeth on the
rolls, preventing side-to-side movement. Belt coverings are
available in a variety of materials for your needs. Walk­through style belt guards ensure operator safety while allow­ing access to the belts. The belt speed is controlled by eye­level controls.

One (model 320) or two (models 426) threaded rods control
the distance between the upper and lower belts. On 320 units,
the top and bottom belts open from a common, fixed center.
For 426 units, each belt adjusts independently, allowing the
operator to fine-tune the machine height.

Rubber grommets (320) or a 90-pound die spring (426) allow
the upper belt to 'give' slightly, preventing the puller from
being damaged by small lumps of extrudate or other foreign
objects.

After passing through the belts, the pulled material continues
on to the cutter. The cutter is mounted on linear slides that
allow as much as 6 inches of movement. The cutter can be
moved away from the puller for startup, then moved close to
the puller to enhance delivery to the cutter bushings.

The cutter's servo motor, which is positional control, is direct
coupled to an in-line planetary gear reducer and drives the
cutter head, or on L models (light duty) the cutter head is
attached directly to the servo motor.

The cutting knife, attached to the cutter head, is driven by the
servo motor. Two cutter bushings guide and support both the
extrudate and the cutting knife. The extrudate passed through
the cutter bushings and is cut by the rotating cutter head (step

3). The cutter head is mounted directly to the in-line planetary
gear reducer shaft using a Trantorque coupling device, and
may have as many as one optional blade position.

Cut pieces are collected or carried on to further processing by
an optional conveyor (step 4).

Digital belt gap sensor and readout

This option allows the operator to set a zero point, then mea­sure belt gap (in thousandths) relative to this point.

Pneumatic upper belt actuator

An air cylinder assembly that can raise and lower the upper
belt boom assembly is available on 426 models only. Control
can be either manual or electrical.

Remote belt speed control

This option allows puller speed control by an external source.

Electronic totalizing footage counter

This option allows the operator to view how much product has
passed through the puller based on input from an encoder. The
counter may be zeroed at any time and rescaled as needed.

Velocity servomotor with serial operator interface

The standard AC puller drive can be replaced by a velocity
controlled servomotor for applications requiring extreme accu­racy.

Different reducer ratios

A particular reducer ratio is selected at the time of purchase to
optimize puller performance in a particular speed range.

Cutter Bushing Lubrication

This is a self-contained spray system, which includes a reser­voir and air inlet for operation at 20-30 psig (air source not
included). Aflexible nozzle directs lubricant onto the extru­date as it enters the cutter bushings. This decreases bushing
drag and helps lubricate the blade. This option is particularly
recommended for processing sticky/soft (low durometer)
materials.

Cutter Blade Wipe

The blade wipe system keeps the cutting blade clean by
removing lubricant and particles from the blade. Areservoir
chamber with a flexible drip tube feeds lubricant to a felt pad
sandwiched between two pieces of stainless steel in the lubri­cation tray. The pad wipes and lubricates the knife before each
cut.

End Sense

This option allows the use of an electric eye to produce a cut
signal. Two types of electric eye brackets are included:

● A bracket for cutting parts 3.5-24 inches long. This

bracket is mounted on the bushing holder, and uses a
photo eye positioned above the extrudate for easy setup,
alignment, and adjustment. NOTE: For this bracket and eye
mounting, the part must be rigid enough not to sag or flex
at the cut distance.

● A bracket for cutting parts up to 10 feet long. This

bracket mounts on a discharge conveyor. The electric eye is
a through-beam type and can be adjusted to sense products
that are at least 0.100" high (height of piece above the con­veyor).

Cutting torque upgrades

Several options can be used to increase the cutting torque:

● CSC 3 cutters can be upgraded from a 2.46 HP

(MGE-455) to a 3.75 HP (MGE-490) servo motor. (The
larger servo motor is standard on SCE-4, 5 cutters.)

● The standard aluminum cutter-head can be replaced

with a heavier stainless steel one. When this option is
picked, the maximum number of cuts per minute decreases.
However inertia, and thus cutting torque, is increased sig­nificantly.

Follower Cutting Mode

Follower mode allows the operator to program the desired cut
length and the number of blades. The controller then automati­cally follows the puller and adjusts the speed of the flywheel
to maintain cut length accuracy. This is known as an electron­ic gearlock system. The cut length accuracy is maintained
even if the puller changes speed.

Auto Cutting Mode

Auto Cutting mode allows the operator to program the desired
cut length and the number of blades and desired blade speed.
The controller then automatically follows the encoder and
adjusts the speed of the cutter head to maintain cut length at
desired blade speed. This is known as an electronic gearlock
system. The cut length accuracy is maintained even if the
puller changes speed. A3,000 pulse per revolution encoder is
used for this option with a Quadrature (x-4) mode, giving
12,000 pulses per foot for extreme accuracy and repeatability.

Discharge Conveyor

A discharge conveyor offers support before, during, and after
cutting, and facilitates the removal of cut parts. Discharge
conveyors are available in the following sizes:

● 6 inches wide by 6 feet long

● 6 inches wide by 12 feet long

● 6 inches wide by 16 feet long

Isolation Transformer

The isolation transformer protects sensitive electronics from
incoming power, which helps prevent errors caused by electri­cal noise. It also protects equipment from electrical noise gen­erated by the servo motor and associated amplifier.
NOTE: An isolation transformer will not compensate for a
ground that does not meet code requirements.

Left to Right Machine Operation

This option changes the machine direction from the standard
right to left extrusion flow.

Your Conair sales representative can analyze your needs and
recommend the options that are right for your system.

NOTE: Conair strongly recommends using an
isolation transformer. Ensuring clean and proper
power can help avoid the need for costly service
calls.
