Description
- The present disclosure relates to a device for processing threads or yarns of textile fibers and, in particular, for controlling and optimizing the processes of working threads or yarns of textile fibers, as well as a device for weighing at least one feeder spool of a thread or of a yarn.
- In the textile industry, various types of devices are known and widely used for processing and/or treating threads or yarns.
- A major problem common to all devices for processing threads or yarns, such as straight or circular knitting machines, is the problem of correctly identifying the amount by weight of threads or yarns of the various different types necessary, i.e. used, for the production of a certain quantity of textile products (be they socks, sheets, sweaters etc.).
- Nowadays, to perform the estimate of the amount by weight of threads or yarns necessary for the mass production of a certain number of textile products, a “sampling” is carried out.
- Firstly a weighing scales is used to weigh the weight of all the spools of the yarns necessary to weave such products.
- Then the spools are positioned on the corresponding supports, the threads of each spool are connected to the straight frame or to the circular machine, and a preset number of products are produced (for example one hundred).
- At this point, after stopping the machine, the spools are weighed again, after cutting the threads and tying the ends of the thread remaining in the machine to a retaining area.
- In this manner, it can be more or less correctly estimated how much thread from each spool has been used to make such preset number of products.
- From the foregoing, it clearly emerges how laborious such method is, even if no problems arise while carrying out the sampling operations.
- However, it is found that very often, during the sampling operations, the threads can break or defects can be present in the finished products.
- This means it is necessary to carry out the entire estimation process again.
- However, very often, in order to save time the operation is simply resumed, making the machine complete the number of products envisaged.
- This inevitably results in an approximation of the estimate with consequent errors, which may be considerable, in the evaluation and purchase of the amount of yarns necessary for the mass production.
- Furthermore, during production it is also extremely important to be able to verify, in real time, whether the thread used up for each product corresponds to the expectations arrived at in the estimation phase, not least in order to have control over the amount of thread or yarn purchased and consumed.
- The aim of the present disclosure is to make available a device for processing threads or yarns of textile fibers that is capable of reducing, or at least drastically limiting, the above mentioned drawbacks.
- Within this aim, the present disclosure provides a device for processing threads or yarns of textile fibers that makes it possible to estimate and control extremely reliably the amount by weight of yarns necessary for the mass production of a textile product.
- The present disclosure also makes available a device for processing threads or yarn and/or a device for weighing feeder spools that makes it possible to check, continually and continuously, the actual consumption of thread or of yarn during the mass production of textile products.
- The present disclosure devises a device for processing threads or yarns of textile fibers that has a low production cost so as to make its use advantageous from an economic viewpoint as well.
- This aim and these and other advantages which will become better apparent hereinafter are achieved by providing a device for processing threads or yarns of textile fibers according to
claim 1. - Further characteristics and advantages of the disclosure will become better apparent from the description of some preferred but not exclusive embodiments of a device for processing threads or yarns of textile fibers which are illustrated by way of non-limiting example in the accompanying drawings wherein:
-
FIG. 1 is a schematic side view of a textile machine; -

accelerometer 18 is adapted to detect the weight of thefeeder spool 3 that is associated with the supportingbody 19. - Preferably, the supporting
body 19 has an elongated shape along a main direction and is associated, at the other end with respect to theengagement portion 19 a, with anexciter 19 b, for example of the mechanical type or of the magnetic type, which is capable of making the measurement of the change in weight by theaccelerometer 18 more precise. - According to a further aspect of the present disclosure, the
