Retrofits Required To Comply With ANSI / SPI B151.21 2000 - Injection Blow Molding Machines - Safety Requirements for Manufacture, Care, and Use
In order to assess the appropriate package of retrofits for your IBS Injection Blow Molding Machine, please provide your local Uniloy Milacron Parts Sales Representative with the following information:
Machine Serial Number
Machine Model Number
Type of Existing Safety Cage (2 door, 5 door (Gull wing) or other)
Type of Existing Mechanical Safety Stops (above table, below table, or none)
Diameter of Existing 4 Tie Bars (2 blow clamp and 2 injection clamp)
Existing Control Voltage (24V or 110V)
Type of Existing Hydraulic System (flat tank or dual manifold)
Extruded Aluminum Safety Cage Assembly
This item is required for all machines built prior to 1979 because it replaces the previous one piece, air operated cage. Fabricated with an extruded aluminum frame and lexan panels, this new style cage is designed to have a high strength to weight ratio.
This mechanical safety retrofit adds an air cylinder to each re-designed shoe. The position of each shoe is monitored (retract or engage). When the cylinder is energized it retracts the shoe and when it is de-energized the shoe is engaged for safe access. The shoes have been redesigned so that they can engage in an increased range of the mold close portion.
This electrical safety retrofit adds key coded, 3 contact safety switches (2 switches per door) to both the main cage/doors and operator access cage. These switches provide the inputs required to electrically and hydraulically interlock and monitor the status of these doors.
The blocking spool is monitored for correct positioning when one or both of the access doors are opened and closed. Should the spool not move to the "blocked" position when an access door is opened, an electrical signal is sent to the control outputs and shuts off the hydraulic pump motor preventing further clamp movement.
This retrofit assembly provides an interface for defined mechanical, electrical and hydraulic safeties to the machine controller on injection blow molding machinery.
