Title : Device for supplying lubrication points on machines with lubricant

The innovation relates to a device for supplying lubrication points on machines with lubricant, preferably on gears of the drive chain of small offset machines.

The problem of an adequate supply of lubricant to gears, bearings, gears, etc. is usually solved in larger machines by having a central Lubricant supply is provided, where the respective consumers are supplied via appropriate lines. In the case of smaller systems or machines, on the other hand, this type of lubricant supply is quite complex Cannot be used for cost reasons.

Therefore, you usually make do with less expensive options, by applying the lubricant by means of a brush or a similar object of application or directly from the lubricant reservoir to the respective point of the Consumer is applied. It is also common to lubricate gears using drip lubrication with a wick oiler.

The former type of manual lubricant supply requires great care and skill, as improper handling can lead to heavy machine contamination. Due to the cumbersome handling, lubrication is often neglected. The consequence of an inadequate or incorrectly applied lubricating film is then often increased wear, for example on the flanks of the gears. For safety reasons, it is ultimately advisable to only use this type of lubricant supply when the machine is at a standstill. f

The wick oiling also mentioned allows only undefined lubrication, which often uses too much or too little lubricant promotes. In addition, only lubricants with a certain viscosity can be used, so that at all Effect of the suction wick can be used «

There is another possibility of lubricant supply ultimately in the use of so-called "automatic lubricators". These usually consist of one closed lubricant container, which has a corresponding Connection thread is screwed on at the consumer and the lubricant is transferred through an internal pressure system continuously delivers to the consumer for a certain period of time. These automatic lubricators are suitable especially for more or less closed lubrication spaces.

The amount of lubricant that flows evenly every day over the specified dispensing period does not take any Consideration of the actually existing, possibly very changing needs. In addition, the submitted The amount of lubricant depends very much on the ambient temperature, so that an undersupply or possible oversupply, at least for a short time, cannot be avoided.

Proceeding from this prior art, the innovation is the task of showing a possibility, in particular to supply the gears of the drive chain in small offset machines with lubricant in such a way that that reliable lubrication can also take place while the machine is running, whereby this should continue to be guaranteed, that the lubricant supply takes place at the desired point, can be aligned according to the actual need can and thus remains independent of temperature fluctuations.

The object is achieved according to the invention by a device with the features of claim 1.

Embodiments are shown in the figures, here

shows:

1 shows the side view of a small offset machine with the lubricant supply according to the innovation and
Fig. 2 shows the upper section of said machine

a modified supply facility.

The essential structural units of the machine shown in FIG. 1 are that made up of the paper sheets 10 to be printed existing system stack 1 with the feed device 2 for the printing unit, an inking unit 3 and a dampening unit 4, which use the application roller 5 to color the plate cylinder 6, which transfers the print image to the blanket cylinder 7, from where it is transferred to the sheet of paper 10 by the pressure of the impression cylinder 8. The following Chain delivery 9 then transports the individual sheet of paper 10 to the delivery stack 11 Control panel 12 attached to the side wall of the machine, the various machine functions are set in motion or controlled.

The individual cylinders and rollers of the entire drive chain are usually driven by helical teeth Gears, which are in contact with one another, arranged on the same shaft of the associated cylinder and are not shown here for the sake of simplicity

25 become.

For their lubricant supply, in one embodiment, the one mounted on the shaft 13 of the rubber cylinder 7 A lubricant reservoir 14 is assigned to a gearwheel. This is by means of a holding device 15 on one side wall 16 attached to the machine. The attachment by retaining clips 17 enables an easy to carry out Replacing the lubricant reservoir 14. The lubricant

outlet opening 18 is on said gear wheel of the drive chain directed in the immediate vicinity of a subsequent meshing point 19 with a further gear.

In order to trigger the lubricant delivery, there is an inside the machine on the side wall 16 in the pivot point 20 rotatably mounted operating lever 21 is provided, its manual to serving end 22 protrudes slightly from the rear boundary of the machine. The operating lever 21 is still provided with a release cam 23, which is responsive to the pressure load release mechanism 24 "of the Acts on the lubricant reservoir. A tension spring 25 and a stop 26 determine the rest position of the operating lever 21.

This means that the lubricant supply can be tailored to the task at hand be done in a safe manner while the machine is running. It always happens in the right place, while the interval between the individual lubrications and their duration can be determined by the operator at his own discretion can be set.

Another embodiment of the device according to the innovation is shown in FIG. With otherwise the same structure, the lubricant reservoir is in this embodiment 14 is associated with an electromagnet 28 fastened to the side wall 16 of the machine by means of a holding device 27. The upper part 29 of the electromagnet, which moves in the direction of the arrow when it is triggered, in turn acts the release mechanism 24 of the lubricant container 14 which reacts to pressure load.

A lead 30 connected to the electromagnet 28 leads to one on the control panel 12 for the machine functions attached switch 31, on the time and duration of the activation of the electromagnet 28 in turn can be controlled manually.

Starting from the basic idea according to the innovation, there is of course the possibility of different types of Lubricant containers such as aerosol cans, grease guns etc. to use. This can of course have the consequence that the various actuating devices for the trigger mechanism 24 must be modified. This is within the scope of the innovation shown.
