AS 4024.3406:2018 Safety of machinery
3.2.7.3  Film removing machines
Film removing machines remove the fim from palletised or unpalletised product. Usually the fim is cut vertically by a cutting device and then removed by low pressure. Mostly a product centralising assembly is used to hold the product. The machine is usually loaded automatically by a pallet conveyor which usually comprises an integrated lifting platform.
The principle components are: cutting device, film removing assembly, flm repository, conveyor with lifting platform.
4 List of hazards on pallet wrapping machines
4.1 General
This clause lists all the significant hazards, hazardous situations and events that can be found on typical pallet wrapping machines including integrated transport, feed and discharge devices.
Before using this standard, the manufacturer shall establish that the hazards on his machine correspond to the hazards described in this standard.
If the manufacturer identifies hazards that are not listed in this clause, he shall assess these hazards by using the principles detailed in EN ISO 12100.
The hazards on a specific machine can vary depending on its working principle; the type, size and mass of the product; the packaging material; auxiliary equipment attached to the machine and the environment in which the machine is used.
The hazards which occur on most pallet wrapping machines are listed in 4.2 and the hazards which are specific to particular types of pallet wrapping machines are listed in 4.3 to 4.5.
4.2.1.1 Moving parts
Pallet wrapping machines may incorporate moving parts which present a variety of mechanical hazards including crushing, shearing， cutting, entanglement, friction and drawing-in. Some of these hazards may persist after the power supply has been cut off due to stored energy.
4.2.1.2 Pneumatic and hydraulic equipment
Pneumatic and hydraulic equipment presents crushing, shearing, ejection of parts and injection of fluids hazards. Stored energy in pneumatic or hydraulic systems may cause mechanisms to move unexpectedly even when power supplies are disconnected. In addition hydraulic oil and pneumatic lubricating oil present a potential fire hazard and can contaminate agri-foodstuffs.
4.2.1.3 Slip, trip and fall hazards
Slip accidents can occur if liquids or solids from the machine e.g. lubricants, packaging materials or the product, spill onto traffic routes, work stations or means of access around the machine.
Trip accidents may occur if parts of the machine protrude beyond the machine frame at low level, or if cables and pipes associated with the machine are incorrectly installed.
Falls may occur if people climb or stand on parts of the machine above floor level, e.g. for magazine loading,size changing, maintenance or cleaning.
