Abstract

The invention relates to a device for the lubrication of rotating, oscillating or translationally moving machine elements in processing machines, in particular printing machines, wherein the machine elements have lubricant users. The object of the invention is to provide a device with which a lubrication of moving machine elements during the machine run is automatically possible. According to the invention, the object is achieved by providing a lubricant dispenser, movably arranged on the moving machine element and temporarily in contact therewith on the movement path, in such a way that the lubricator in one working position automatically transfers lubricant to the lubricant recipient arranged on the moving machine element , Fig. 1 {Printing Machine; Lubrication}

Description

Field of application of the invention

The invention relates to a device for lubricating rotating, oscillating or translationally moving machine element in processing machines, in particular printing machines, wherein the machine elements have lubricant users.

Characteristic of the known state of the art It is known to lubricate moving machine elements at their standstill by hand. This has the disadvantage that the reliable dosage is not guaranteed at the right time for all lubrication points. Out Inadequacy, such as forgetting lube points, confusing or contaminating the lubricant arise

more nights.

Furthermore, the lubrication points are often difficult to access and manual lubrication requires a lot of work,

which ultimately leads to a reduction in productive time.

When manual lubrication is also a danger to the operator by unintentional switching on the machine

or by slipping during handling. Finally, due to lack of lubrication on the product of

Processing machine quality defects occur. Object of the invention

The aim of the invention is to eliminate the manual effort and the threat to the operator when lubricating machine elements.

Explanation of the essence of the invention

The object of the invention is to provide a device with which a lubrication of moving machine elements during machine operation is automatically possible.

According to the invention, this object is achieved in that the mounted on the moving machine element lubricant 3r a movably arranged on the machine frame and with this on the trajectory temporarily in contact lubricator is assigned so that the lubricator automatically passes in a working position lubricants arranged on the moving machine element lubricant user ,

embodiment The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing show Fig. 1: schematic representation of the grease lubrication of rotating machine elements in the starting and working position of the

Lubrication unit Fig. 2: schematic representation of the grease lubrication of rotating machine elements in the reversing position of the lubrication unit.

A rotating machine element 1, the z. B. a sheet guiding cylinder of a sheet-fed rotary offset printing machine, carries on its front side a lubricant holder 2. From the lubricant holder 2 are arranged in the sheet guiding cylinder bearings supplied with lubricant. The lubricant receiver 2 is mounted on a rotatable distributor shaft 3. In the frame 4 of the machine, a holder 6 is rotatably mounted about the frame point 5. In the holder 6 a SchmieiStoffgeber 7 with a piston 8 and a mouthpiece 9 is slidably disposed.

The displacement of the lubricator 7 in the holder 6 takes place in the embodiment with a linkage 10. The drive for the movement of the linkage 10 is not shown in more detail in the drawings. It can be done in a known manner by mechanical, but also by electric or hydraulic drives.

In Fig. 1, the holder 6 is in the starting position. By a spring 11, the holder 6 is pulled to a stop 12. About the lubrication line 13 of the lubricator 7 is filled with lubricant. By means of a switching mechanism, not shown, the linkage 10 is moved and the lubricator 7 in the working position (dash-dotted lines in FIG. 1) brought.

Upon rotation of the Bogenführungszyiinder 1, preferably At creep speed of the machine, enters the Schmlerstoffnohmer 2 on its trajectory with the standing in Arbeltsstellung lubricator 7 through the mouthpiece 9 in contact. Upon further rotation of the Bogenführungszyiinder 1, the holder β is pivoted about the Qeienkpunkt 6 and thereby transferred by displacement of the piston 8 relative to the Schmlorstoffgebor 7 of the lubricant to the Schmiorstoffnehmer 2. In a further rotation of the Bogonführungszylinders 1, the contact between Schmhrstoffnohmer 2 and dom mouthpiece 9 of the Schmiorstoffgebers 7 is repealed (reverse position, Fig. 2), the spring 11 pulls the holder 6 with the Schmierstoffgebor 7 back to the starting position. By Schalton dos Golenkgotriobos 10 of the lubricant Gober 7 is brought out again in soino starting position from the movement path of the Schmlerstoffnohmers 2. A renewed lubricant transfer is reintroduced when the replenished Schmierstoffgebor 7 is driven by the Golonkgetriebes 10 via the switching device in the working position.
