Description

The roller lock that is used for printing machine

Technical field

The present invention relates to a kind of roller lock for printing machine as described in the preamble in claim 1, it comprises and presses down keeper, and the described keeper that presses down radially is fastened on roller in locked position of coupler in the roller lock.

Background technology

In having the printing machine of anilox inking unit (for example at US7, in the printing machine that 607,390B2 describes), adopt anilox roll to carry out the printing ink metering.

For example for cleaning purpose, but the intermediate calender rolls combined pressure is on anilox roll, as described in DE102007001948A1.The intermediate calender rolls of describing in the document is bearing in roller lock, and described roller lock comprises and presses down keeper.

A kind of such roller lock has also been described in DE4243657A1.What describe in the document is, realizes pressing down the kayser of keeper when the roller locking closes by pressing down respective shapes between keeper and bearing body.

The kayser that presses down keeper also can be realized by other means.Two kinds of flexible programs have been described in EP0734857B1.In a flexible program, press down keeper and be provided with the prismatic guider and have ball formula buckling and locking device in another flexible program.

In the prior art disadvantageously, same member is used as in functional unit and presses down keeper and be used as dead bolt.In order to make this member can satisfy it as pressing down the function of keeper and roller being clamped reliably, the spring load of described member must be very large.Only in the situation that spring force is large just can guarantee roller sufficiently is pressed onto roller lock in and be fixed on the there.But large spring load makes operating personnel's release become difficult, and the effect of described release antagonistic spring power is carried out.Therefore, described member can not sufficiently satisfy it as the function of dead bolt.

Summary of the invention

Task of the present invention is, a kind of roller lock is provided, and described roller lock is stationary roll and can simple operations reliably.

Described task solves by the roller lock with claim 1 feature.Roller lock for printing machine of the present invention comprises that one presses down keeper, and the described keeper that presses down radially is fastened on a roller in locked position of coupler in described roller lock.The described keeper that presses down loads by the first spring.In addition, the described keeper that presses down can rotate in described locked position of coupler around an imaginary rotation and is supported.The described keeper that presses down can be locked in described locked position of coupler in addition.Roller of the present invention lock is characterised in that, the described keeper that presses down can be locked in described locked position of coupler and described dead bolt loads by the second spring by a dead bolt.

In roller of the present invention lock, cancelled the functional unit that exists in the prior art and pressed down keeper and dead bolt is two members that differ from one another.By the existence of the second different springs, a spring can design like this, makes it by pressing down keeper stationary roll reliably, and another spring can design like this, easily operates dead bolt when making it guarantee release.
