DETACHABLE MAGNET HOLDER
|Abstract||The invention relates to a universally applicable detachable magnet holder with a fixed magnet and an opposite-lying magnet which can rotate about a point of rotation and which is provided with magnet pole surfaces, wherein each magnet pole surface comprises at least two poles which, when closed, attract each other and which, when open, repel each other once the rotatable magnet has been rotated by means of an actuation device. According to the invention, a distance element (7), made of a non-ferromagnetic material, is fixed to one of the magnet pole surfaces, whereby the bearing surface on the opposite magnet pole surface is a maximum 1/3 of the surface and a centering engaging device (10a, 10b; 11) is arranged in the vicinity of the magnet poles in order to receive magnetic sheer forces.|

3. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed : -
The invention relates to a bearing, especially a printing machine bearing.
The bearings of printing machines are components under high load, whose wear and tear status or expected working life and their maintenance depend on conditions, under which the bearings are operated. Thus, for example, vibration stresses, radial forces acting on the bearings, bearing temperatures and bearing rollovers have influence on the maintenance intervals for the bearing as well as wear and tear status and thereby the working life of the same. So far from the state of technology no bearing is known, which would provide clue regarding the wear and tear condition of the same. Therefore, normally bearings are serviced or even replaced in certain intervals as a routine, whereby bearings are serviced or replaced either too early or too late. In case of bearings serviced or replaced too early, the same could have been used longer based on their wear and tear condition, whereby increased costs are incurred. If bearings are serviced or replaced too late, then due defects unscheduled downtimes of the printing machine are caused, which lead to production failure and cost escalations.
Considering the above situation the present invention is based on the problem to develop a new kind of bearing. This problem is resolved through a bearing according to claim 1. The invention based bearing covers an especially active RFID (Radio Frequency Identification) device, which on the one hand is writeable and on the other hand readable, wherein the RFID device in first operating mode, i.e. in a receiving mode, receives bearing data and saves it, and wherein the RFID device in second operating mode, i.e. in a transmission mode, transmits the data recorded and saved in the first operating mode.
In the sense of the present invention a bearing is suggested, which covers an RFID device. The RFID device receives in first operating mode bearing data and saves it. In second operating mode the RFID device transmits the saved bearing data. The invention suggests a bearing, in which case bearing data about the stress on the
bearing and thereby the wear and tear condition of the same can be automatically saved and read in the RFID device. Hereby, stress conditions as well as wear and tear conditions of bearings can be precisely monitored, so that bearings - dependent of their wear and tear condition - can be serviced or replaced at the right time. Hereby cost advantages emerge,
For this purpose in preferred manner an active RFID is used, however, for a query regarding current operating parameter also a passive RFID is also possible, that means an RFID, which takes over energy required for obtaining and transmitting the data from the HF field of the querying read device.
Further developments of the invention emerge from the sub-claims followed by the description below. Design examples of the invention, without restricting to these, are explained in more details on the basis of drawing. It shows as follows:
A schematic representation of an invention based bearing.
Fig. 1 shows on high schematic basis a bearing 10 for a printing machine, wherein the bearing 10 covers an RFID device 11. RFID is the acronym for Radio Frequency Identification. The RFID device 11, here, is designed as active device, which has its own voltage supply or power supply by means of a battery, and which on the one hand can receive and store data and on other hand can transmit data.
In the sense of the present invention the RFID device 11 of the bearing 10 can be operated in two operating modes, namely in first operating mode, in which the RFID device 11 receives and stores bearing data measured by sensors 12,13,14,15 and 16 and in second operating mode, in which the RFID device 11 transmits previously stored data. The first operating mode is also known as receiving mode and the second operating mode as transmission mode.
The bearing data, which is received and stored in the first operating mode of the RFID device 11, can be momentary values of the bearing data. Therefore, in the shown design example of the Fig. 1 the sensor 12 provides temperature values of the bearing. The sensor 13 provides speed values, the sensor 14 force values, preferably radial force values, and the sensor 15 frequency values of vibration conditions of the bearing. These momentary values are transmitted by the sensors 12 to 16 and are received and stored by the RFID device 11.
Besides, such momentary values in the first operating mode also cumulative and integrated bearing parameters about the operation of the bearing can be received and stored: wherein in the shown design example the sensor 16 measures respective rollover values of the bearing 10 and transmits these, which are in turn again received and stored by the RFID device 11.
In the sense of the present invention it can be provided that the RFID device 11 in regular time gaps or intervals receives and stored bearing data from the sensors 12 to 16. Further, it can be provided that the RFID device 11 depending on the operating condition of the bearing especially dependent of the operating condition of a printing machine, in which the bearing is used, changes over to the first operating mode and then receives bearing data from the sensors 12 to 16 and saves the same.
In the sense of the present invention it can also be foreseen that the RFID device 11 over a certain time interval continuously receives bearing data measured and transmitted by the sensors 12 to 16 and stores it.
In the sense of the present invention, according to it a bearing 10 is suggested, which has an RFID device 11 for receiving and storing of bearing data. Sensors 12 to 16 allocated to the bearing 10 measure the bearing data and transmit the same to the RFID device 11.
With the help of a reading device 17 the data stored in the RFID device 11 of the bearing 10 can be read. For this purpose, the RFID device 11 in the second operating mode transmits the previously received and transmitted bearing data to the reading device 17. The transmission of the bearing data stored in the RFID device 11 by the RFID device 11 can be initiated here by the reading device 17.
During the time when the RFID device 11 serves neither in the first operating mode to receive and store bearing data nor in the second operating mode to transmit it, the RFID device 11 is preferably in a standby mode to save energy.
I CLAIM :
1. Bearing, especially of a printing machine, with an especially active RFID (Radio Frequency Identification) device (11), which is on the one hand writeable and on the other hand readable, wherein the RFID device (11) in first operating mode, namely in a receiving mode, receive and store bearing data, and wherein the RFID device in second operating mode, namely in a transmission mode, sends data received and stored in the first operating mode.
2. Bearing as per claim 1 characterized by the fact that the RFID device (11) in the first operating mode receives momentary values of bearing parameters as bearing data, especially temperature values and/or speed values and/or force values and/or frequency values.
3. Bearing as per claim 1 or 2 characterized by the fact that the RFID device (11) in the first operating mode receives as bearing data the bearing parameters cumulated or integrated over the operation of the bearing, especially rollover values.
4. Bearing as per one or several of the claims 1 to 3 characterized by the fact that the RFID device (11) depending on the operating condition of the bearing, especially that of printing machine, changes over to the first operating mode and receives and stores bearing data.
