DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a yarn supply device group for attaching to a textile machine, in particular a ring knitting machine with electrically controllable switching or actuating elements in every supply device which are connected in a signal-transmitting circuit to a central control mechanism by a bunch of lines common to all devices.
BACKGROUND OF THE INVENTION
From European Patent Application No. 801 067 19 (corresponds to U.S. Pat. No. 4,386,508) is known to construct a bunch of lines as a flat multi-conductor cable, in which at least as many conductors or wires are arranged side-by-side as there are supply devices in the supply device group. Since for example fourteen or more supply devices can be associated with one knitting machine, and since for every supply device, if necessary, several lines or wires in the bunch of lines are needed, the bunch of lines has considerable dimensions and is difficult to store, due to extremely cramped space conditions. Furthermore, the function-correct connection and "marking" of the supply devices, prior to the first use of the textile machine or after rearrangement or the connecting or "marking" of one or several exchanged supply devices, is extremely expensive. It is namely necessary that an operator manually and suitably position one or several contact pins inside of the supply device, so that the suitable circuit connections between the switching or actuating elements and the central control mechanism are formed. This manual "marking" in addition is time-consuming and causes an undesirably long stand-still time for the textile machine.
The basis of the invention is the technical problem of how to construct a yarn supply device group of the above-identified type so that the structural provisions for connecting the supply devices to the central control mechanism are considerably reduced and so that mainly the adjusting or "marking" of the supply devices in the supply device group is simplified and can be carried out more quickly.
SUMMARY OF THE INVENTION
The set problem is solved inventively by providing a yarn supply device group in which each supply device has an electronic switching arrangement which contains a writable and readable memory associated with the switching or actuating devices, which can be supplied with a unique address from the central control mechanism and which, after having been supplied with the address, can be controlled by being addressed, wherein the switching arrangements of all supply devices are connected in the same manner to the bunch of lines.
In this construction, due to the electronic switching arrangement, to which can be fed an address from the central control mechanism, a manual marking of each supply device is not necessary. As soon as operation starts, the central control mechanism supplies an address to each electronic switching arrangement, under which address then during operation each supply device can be controlled individually. This means that the supply devices of the group need only be fixed mechanically without "marking" and that then the textile machine is immediately ready for operation. A further, important advantage consists in the bunch of lines containing only a small number of lines, since all supply devices are connected in the same manner to the same lines, so that the connection can be carried out relatively simply and the structural parts and the space for storing the bunch of lines is considerably reduced, because it is no longer necessary to select for each supply device a specific line or lines. The bunch of lines can be integrated structurally without any difficulties into the supply device group or the storing of the group, so that little space is needed for the bunch of lines and it no longer hangs around interferingly between the individual supply devices and the central control mechanism. The standstill times of the textile machine, prior to starting operation, after breakdowns in operation, after change-over operations during which, if necessary, individual supply dev
