Abstract

This tube has a tubular body (1) for positioning on any of the output spindles of continuous spinning machines, and a chip (2), which may be pre-recorded or remotely recordable, attached to the tubular body (1) for containing information enabling the tube to be identified or the position occupied by that tube in the spinning machine to be ascertained. The chip (2) may be attached to the outer surface of the tubular body (1) or inserted into the material of which the tubular body (1) is made.

Description

DESCRIPTION

TUBE FOR YARN WINDING IN CONTINUOUS SPINNING MACHINES

OBJECT OF THE INVENTION

The invention relates to a tube for winding the yarn produced by continuous spinning machines of the kind that have a tubular body positioned over one of the output

■ spindles of said continuous spinning machines and on which the yarn is wound.

BACKGROUND OF THE INVENTION

Continuous spinning machines have a number of spindles or spikes over which a tube or bobbin is positioned and on which the yarn produced by the machine is wound. When a tube has collected a pre-established volume of yarn, the yarn-bearing tube is taken away from its spindle and on to the next phase in the process, which may be winding, weaving, storage, laboratory work etc. These tubes or bobbins are all the same, and so it is difficult or even impossible subsequently to ascertain at which spindle they were loaded with^' yarn.

Not being able to ascertain the source spindle is a problem at present: if a manufacturing problem is detected in the yarn on a particular tube, the machine and the machine part involved ' in the manufacture of the yarn cannot be traced, and consequently the machine cannot be adjusted to prevent it from continuing to produce defective yarn.

Thus, arranging stringent and effective quality control poses great problems, since the exact point of manufacture of yarns that are subsequently found to be defective is not known.

DESCRIPTION OF THE INVENTION To remedy these problems, the tube of this invention for winding yarn in continuous spinning machines was conceived, since it affords constructional features that are intended to facilitate the location of the spindle from which the yarn was wound onto the tube, thus ensuring effective assistance in quality control. The tube is of the kind comprising a tubular body for positioning over one of the output spindles of continuous spinning machines and having the yarn produced by the machine wound onto it.

According to this invention, the tube has a chip attached to the tubular body, which is for containing information enabling the source position to be ascertained at any time, i.e. the position occupied by that tube in the spinning machine during the process of winding the yarn onto the tube . This chip may be attached to the outer surface of the tubular body, using an adhesive for example, or it may be inserted into the material of which the tubular body is made. However, as long as the chip remains operational in the tubular body for which it is destined, how it is attached to that body is of no significance.

This chip may be re-recordable by remote control in such a way that the information on the position occupied by the tube in the machine, the date and time of production of the yarn wound onto it and any other data of interest may be recorded in the chip when the yarn-bearing tube is removed from the spinning machine, the information then remaining in that chip when the tube has left the machine.

Thus the information recorded in the re-recordable chip .at the output from the spinning machine enables the source machine, the spindle at which the tube was positioned, the yarn-manufacturing shift and time, and any other information deemed pertinent and recorded in the chip, to be ascertained at the winding stage, in the laboratory or elsewhere. In this way, any quality problem encountered in the yarn can be suitably remedied by performing the adjustment required in the spinning machine, since the production line responsible for the defective yarn is known for certain.

Optionally, the chip attached to the tube can be a pre-recorded chip, in which case it would feature a number or code enabling the tube to be identified at any time. In this case, the arrangement would be that computer equipment would cross-link the identification number of the chip to the information required (the source spindle, the date and time of manufacture of the yarn etc.), the cross-linking information being stored in the computer equipment rather than in the chip .

Under this option, the information does not have to be re-recorded in the chip, since the information, together with the number or code identifying the chip (and thus the tube) is recorded in said computer equipment, which means that this solution is more advantageous in economic terms .

DESCRIPTION OF THE DRAWINGS

To supplement the description now being given, and in order to facilitate understanding of the characteristics of the invention, a set of drawings is attached to this specification showing the following and illustrating, but not restricting, the invention:

- Figure 1 shows a perspective view of a tube for winding yarn in continuous spinning machines, with the chip appearing attached to the outside of the tubular body.

- Figure 2 shows a sectional elevation view of a tube with the chip inserted in the material of which the tube is made .

PREFERENTIAL EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the tube for winding yarn in continuous spinning machines comprises a tubular body (1) to which a pre-recorded or remotely re-recordable chip (2) is attached. Figure 1 shows an embodiment in which the chip (2) is attached to the outer surface of the tubular body (1) , while in the example of embodiment shown in Figure 2 the chip (2) is inserted in the material of which the tubular body (1) is made, forming a single unit with it.

If the chip (2) is pre-recorded, it will contain an identifying number or code, while if it is remotely re- recordable, it will contain, on being removed from the spinning machine, information on the position the tube had occupied in that spinning machine or any other information concerning the manufacture of the yarn wound onto the tube concerned, this information remaining in the chip (2) when, the tube is removed from its position in the spinning machine . Thus the information contained in the chip (2) , whether pre-recorded or remotely re-recordable, will enable the tube source information to be obtained. If the chip is pre-recorded, said information will be obtained from the computer equipment that cross-links the chip's pre-recorded code to the source information, while if a re-recordable chip is used, the information will be obtained directly from the chip (2 ) .

Having provided sufficient description of the nature of the invention, and an example of preferential embodiment, it is stated to all effects and purposes that the materials, form, size and arrangement of the elements described may be modified provided that such modification does not alter the essential characteristics of the invention, which are claimed hereunder.
