MACHINE TOOL

Abstract

In order to provide an operating method for a machine tool and to propose a system which enables the monitoring of the installation, position and the like of tools in a respective machine without the need for major construction work, the disclosure proposes a system for assigning tools mounted on rams to an installation position on a machine, which consists of a writable RFID chip with a transponder, memory and passive digital inputs positioned on the ram, and an electrically switchable contact panel positioned at a connection position of the machine, whereby the contacts of the contact panel can make contact with the digital inputs and the RFID chip transmits at least one identifier and the assignment of the digital inputs during a query process.

Claims

1-14. (canceled)

15. A system for assigning tools mounted on rams to an installation position in a machine, comprising: a RFID chip, which is arranged on a ram, which is writeable, which has a transponder, which has a memory, which has passive digital inputs, and an electrically switchable contact panel, with contacts, which is arranged on a tool holder of the machine, wherein the contacts of the contact panel can be contacted to the digital inputs of the RFID chip, and the RFID chip transmits at least one identifier and the assignment of the digital inputs during a query process.

16. The system according to claim 15, wherein the digital inputs are contacted directly at the contact panel of the machine if the ram is mounted as intended.

17. The system according to claim 15, wherein the contact panel arranged at the connection position of the machine shows four contacts, each of which can be contacted with a digital input of the RFID chip.

18. The system according to claim 15, wherein the RFID chip includes information on the tool.

19. The system according to claim 15, wherein this is realised in a deep rolling machine.

20. The system according to claim 19, wherein the ram is designed as tool heads, i.e. as a deep rolling head and as a support roller head of the deep rolling machine.

21. A method for operating a system for assigning tools mounted on rams to an installation position in a machine, comprising: arranging a ram having an RFID chip which is writeable with information on the tool, and which has a transponder and a memory, wherein passive digital inputs of the RFID chip make contact with a contact panel on the machine which is located at a connection position of the machine, whereby at least one identifier and the assignment of the digital inputs are transmitted by the RFID chip during a query process.

22. The method according to claim 21, wherein RFID chips are arranged in a deep rolling head as well as in a support roller head of a deep rolling machine and that the machine has contact panels at all connection points.

23. The method according to claim 21, wherein the installation position of a tool head is inferred from the information transmitted by the RFID chip about the wiring of the inputs of the RFID chip.

24. The method according to claim 21, wherein the tool is inferred from the information transmitted by the RFID chip about its description.

25. The method according to claim 21, wherein the information transmitted by the RFID chips is evaluated for component monitoring.

DETAILED DESCRIPTION

[0041] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0042] The FIGS. 1 and 2 show an example of an arrangement on a machine. In the illustrated design example, the tool holder 1 and the tool holder 2 of a machine are equipped with rams 3 and 4, which in turn carry the tools 5. In the illustrated design example, these are rollers for rolling.

[0043] Contact area 6 is arranged between the tool holder 1 and the ram 3, in which a contact panel is located on the tool holder side and an RFID chip with a corresponding contact panel is located on the ram. The same applies to the contact area 7 between the tool holder 2 and the ram 4.

[0044] In the illustrated design example, however, the tool holder 2 has a special feature in that a receptacle adapter 8 is arranged between the actual ram 4 and the tool holder 2. Adapter 8 is in contact with tool holder 2 via the contact panel 7, and adapter 8 in turn is in contact with the actual ram 4 via the contact area 9, with the RFID chip and the contact panel on the machine located in contact area 8.

[0045] FIG. 3 shows an example of a contact panel 10, which in the illustrated design example has a base contact 11 and switchable contacts 12. The base contact 11 can be connected to the four switchable contacts 12 shown in any combination. The RFID chip can switch to an electrical voltage or earth (ground) via the base contact 11. By making contact with the contact panel, the RFID chip can now determine the combination of circuitry of the switchable contact panels and deduce the position in accordance with the disclosure.

[0046] FIG. 4 shows a special arrangement of an RFID chip on the ram. Shown is the ram 13, which is the same as ram 3. However, only two contact panels 10 and 17 are provided in contact area 14, which are in contact with each other. The contact panel 17 is in turn connected to the RFID chip 16 via a wire 15. This design can be applied anywhere in the contact areas, in order, for example, to be able to select a safe placement for the RFID chip.

[0047] The described design examples are for explanatory purposes and are not restrictive.

[0048] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are inter-changeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
