The JK824 is our largest slotting machine developed from years of research

and experience in the manufacturing of PVC slotting machines. The JK824 was designed with

a combination of all the innovative ideas we have developed, resulting in a machine proven to be

the most versatile, highly productive, and simple to setup and operate.

The pipe is rotated or indexed by a 1 3/4 HP air motor gear drive system capable of over 1500 inch lbs

of torque. The indexing row stop is controlled by a proximity switch that senses pins on the indexer plate

directly mounted on the 1 1/4" indexer shaft. The indexer can be set for 2, 4, 6, 8, 10, 12, or 14 rows

of slots. Another efficiency feature is the air operated inside pipe holder. The pipe holders will clamp either

plain end or bell end. This unit is equipped with a safety switch not allowing start, if the inside

pipe holder is not engaged.

Because slotter shafts and indexer shaft maintain the same center line 49" from the floor, the lower pipe

support must be raised and lowered to accommodate the different pipe diameters of 8" through 24".

This is achieved by the adjustable center pipe support mounted in the middle of the main frame rail.

The pipe support is raised and lowered by three vertical jacks connected together. Pipe to be slotted

is very easily moved up to ID pipe holder on indexer by series of nylon roller mounted on top of support.

Air Gear Motor for Manual Travel of Slotting Assembly

When the machine is operating in automatic mode, the slotting assembly  will slot, then index the pipe

and travel in the direction towards the indexer end of main frame. At completion of screen the machine will

automatically stop. Slotting assembly must then be returned to opposite end of main frame for the next screen.

This operation is done with the air gear motor manual travel system. Switching for this system is located on

control panel and can be operated in both directions. Automatic stops located on both ends of machine.

Machine is equipped with a 5 HP 3 phase direct drive dust collection blower. Vacuum hoses are directly

mounted to special built fixture surrounding saws on slotter shafts. The fixtures are designed to retract as

saws penetrate pipe allowing a high volume of air to move over saws for cooling and dust extraction.

Dust can then be blown through hose or duct into a collection hopper supplied by customer.

Automated mechanical movements are done by air cylinders, air motor, and air brakes. This method of

automation has proven to be dependable and low maintenance.

Air supply to the machine must maintain 140 PSI at 10 CFM.

The automatic system is controlled by an Omron CPM1 PLC, control input signals come from proximity

switches positioned throughout the machine. Output signals from PLC then go to 24 Volt DC air valves and

control relays. The machine requires one input power supply, either 240 Volt 3 phase or 440 Volt 3 phase.

Control circuit is transformed down to 110 Volt AC and 24 Volt DC.

30 Amp draw at 440 volt 3 phase, 55 Amp draw at 240 volt 3 phase
