WHAT IS MY MACHINE CONCEPT? Jishu Hozen (By Ketan Kumar) 14 It means that everyone carries out Routine Inspection Oiling Parts Replacement Repair Early detection of abnormalities Precision checking of their own equipment
WHY DO MACHINE FAILS?? Jishu Hozen (By Ketan Kumar) 15 Machine fails when they are not taken care of. Just like a human body, we fall ill when we don’t take proper care of our body. Similarly same is for the Machine also.
HOW YOU CAN PREVENT YOUR MACHINE FROM BREAKDOWNS? Jishu Hozen (By Ketan Kumar) 16 Timely cleaning and checking of the machines Knowing about failures before they occur Solving the problems immediately
CHALLANGES Jishu Hozen (By Ketan Kumar) 17
MY MACHINE Jishu Hozen (By Ketan Kumar) 18 In just 3 steps Step-0 Step-1 Step-2 Step-3
ABNORMALITY Jishu Hozen (By Ketan Kumar) 19 Anything that is not in the specifications of the machine manufacturer. Abnormalities:- dirty Loose Hanging Leaking Splashing/spilling Broken Excess length / heat / vibration Unwanted / missing Bent, holes, worn-out Abnormal noise
5. QUALITY DEFECT SOURCES Jishu Hozen (By Ketan Kumar) 29 Abnormality Examples Foreign Matter Dust, Rust, powder, chips, moisture, wire scraps, wood pieces, paper pieces, stones etc. Shock Dropping, Jolting, collision, Vibration etc. Moisture Too little or Too much, infiltration Grain Size Abnormalities in screens, Compressed air separators, centrifugal separators, Concentration Inadequate warming, heating, compounding, mixing, evaporation, stirring etc. Viscosity Inadequate warming, heating, compounding, mixing, evaporation, stirring etc.
5. QUALITY DEFECT SOURCES Jishu Hozen (By Ketan Kumar) 30 FULL OF CHIPS DENTS PROBLEM
6. UNECESSARY & NON URGENT ITEMS Jishu Hozen (By Ketan Kumar) 31 Abnormality Examples Machinery Pumps, fans, compressors, columns, tanks etc. Piping equipment Pipes, hoses, ducts, valves, dampers etc. Measuring instruments Temperatures, pressure gauges, vacuum gauges, ammeters etc. Electrical equipment Wiring, piping, power leads, switches, plugs etc. Jigs & Tools General tools, cutting tools, jigs, molds, dies, frames etc. Spare parts Standby equipment, spares, permanent stocks, auxiliary materials, etc. Makeshift repairs Tape. String, wire, metal plates etc.
6. UNECESSARY & NON URGENT ITEMS Jishu Hozen (By Ketan Kumar) 32 LEAKAGE OF CUTTING OIL UNWANTED AIR PIPE PARTS AFTER INSPECTION
7. UNSAFE PLACES Jishu Hozen (By Ketan Kumar) 33 Abnormality Examples Floors Unevenness, cracked, holes, projections, peeling, wear of steel chucker plates, slipping. Steps Too steep, irregular, slipping, missing handrails, etc. Lights Dim, out of position, dirty or broken covers, no explosion proofing, etc. Rotating machinery Displaced, fallen oil or broken covers, not safe for emergency, missing emergency stop devices Lifting Devices Wires, hooks, brakes and other parts of cranes and hoists etc. Others Special substances, solvents, toxic gases, insulating materials, danger signs, protective clothing etc.
STEPS OF AM Jishu Hozen (By Ketan Kumar) 35 STEP -0 Preparation of Employees Team Formation Arrange Resource for Cleaning STEP -1 Initial cleanup of machines Identify 7 types of abnormalities & Tag it. Capture Pareto of 3 months downtime STEP -2 Take counter measures for the identified tags & Downtime either by restoration or by Kaizen STEP -3 Prepare CLIT standards for the machine Publish near the machine Train the employees for routine verification
STEP O- INITIAL CLEANING Jishu Hozen (By Ketan Kumar) 36 Prepare a Cleaning& Lubrication Map. Arrange tools. Arrange RED & WHITE tags. History of Failures Training on Jishu Hozen (AM) Training on 7 Types of Abnormalities.
STEP 1- INITIAL CLEAN UP Jishu Hozen (By Ketan Kumar) 37 Cleaning is INSPECTION. Use 5 SENSES for cleaning. Find out 7 TYPES OF ABNORMALITIES. Put tags on Abnormalities. Prepare list of UNFULFILLED BASIC CONDITIONS
TAGGING OF ABNORMALITIES Jishu Hozen (By Ketan Kumar) 38 A thorough cleaning will reveal countless problems and conditions that are less satisfactory. We mark it with tags. Attach tags to problems revealed by cleaning / inspecting. Fix the problems right away. Then remove the tags. For a problem that can’t be fixed immediately, draw up a clear plan to remove the tag.
2 TYPES OF TAGS Jishu Hozen (By Ketan Kumar) 39 Red Tag - When abnormalities are to be rectified by maintenance. White Tag- When abnormalities are to be rectified by operators.
STEP 2- ELIMINATE PROBLEM SOURCES & INACCESSIBLE SOURCES Jishu Hozen (By Ketan Kumar) 40 Stop contamination at the source Reduce cleaning and lubrication time Modify equipment to make cleaning and lubrication easier Install covers and inspection windows to make checking easier
