Abstract
An object is to supply a fixed amount of oil determined in advance. In the present invention, a lubricating device that supplies oil to each sliding device of a printing machine includes a lubricating section and a metered valve. The lubricating section ejects oil in an oil reservoir section into a piping when lubrication is performed. The metered valve is configured to eject oil accumulated in an ejection side cylinder chamber from an ejection opening by oil pressure from the oil ejected into the piping. The oil ejected into the piping is accumulated in a supply side cylinder chamber. When a lubricating pump is stopped and depressurized, the oil accumulated in the supply side cylinder chamber moves to the ejection side cylinder chamber.
Claims13
A lubricating device that supplies oil to each sliding device of a printing machine, comprising:
- a lubricating unit that ejects oil from an oil reservoir into a piping when lubrication is performed;
- and
- a metered valve that ejects a fixed amount of oil onto a sliding unit to be lubricated by oil pressure of the oil ejected into the piping.
A lubricating method comprising the steps of:
- counting an actual elapsed operation time during which a printing machine is printing;
- comparing an actual elapsed printing time and an optimal lubrication time set in advance;
- and
- giving a notification when the actual elapsed printing time exceeds the optimal lubrication time.
A lubricating method comprising the steps of:
- counting an actual elapsed operation time during which a printing machine is printing;
- comparing an actual elapsed printing time and a critical time set in advance;
- and
- forcibly supplying a fixed amount of oil after the printing machine stops printing, when the actual elapsed printing time exceeds the critical time.
