The invention relates to a method and a device for combining cheese pairs made up of cheeses of different types, in particular cheeses having different yarn lengths, in a cheese-producing textile machine, having a plurality of adjacent winding stations and having a cheese transporter disposed along the machine, the cheese transporter having an end at which the cheeses become disposed for further availability, the cheese transporter including at least one mobile automatic cheese exchanger for removing the cheeses from the winding stations and reading them for further transport.
Cheese pairs are used, for example, as supply coils in yarn combining devices. Twisters, doubling winders and winders cooperating with coil supply creels are considered to be yarn combining devices.
It is possible that the individual coils of cheese pairs do not outwardly differ in appearance. If one yarn winds around another, for example, in the yarn combining device, it is a matter of chance as to which of the two supply coils supplies the core thread and which the cover thread. For this reason, it is impossible from the very start to consider the different yarn lengths during cheese preparation so that as little as possible wasted yarn results when the yarns are combined. If piecing is to be avoided in the course of the combining process, the cheeses of the one type must have a considerably greater yarn length than would be required for a yarn of a predetermined length made from individual threads. In most cases the remaining lengths are no longer usable for a quality product.
It is accordingly an object of the invention to set the conditions for the most error-free and rapid possible formation of cheese pairs of different types.
With the foregoing and other obJects in view, there is provided, in accordance with the invention, a method of combining cheese pairs made up of cheeses of different types in a cheese-producing textile machine having a plurality of adjacent winding stations and a cheese transporter disposed along the machine, the cheese transporter having an end at which the cheeses become disposed for further availability, the cheese transporter including at least one mobile automatic cheese exchanger for removing the cheeses from the winding stations and readying them for further transport, which comprises automatically transferring the cheeses to the cheese transporter in cooperation with the mobile automatic cheese exchanger: after depositing a row of pairwise arranged cheeses on the cheese transporter, setting the cheese transporter into motion only when at least one of the following has been determined by automatic devices: that the winding stations have delivered the cheeses correctly and in the correct amounts, that the predetermined amount of cheese pairs is present, that irregular pairs of cheeses and excess cheeses are identified as such and that the original winding station of irregular cheeses has been identified.
In accordance with another mode of the invention, there is provided a method which includes automatically depositing the cheeses of a first type in a row at spaced distances from one another equal to more than the length of a single cheese, respectively; and subsequently depositing the cheeses of a second type, respectively, into the spaces between the cheeses of the first type.
